[0005] Patent Document 1: Japanese Patent Application Publication No. 2020-040877 Summary of the invention Technical problem to be solved by the invention

[0006] In addition, a method widely used for grinding the periphery of various glass plates of different shapes as processing objects (chamfering devices) is to process by biting into the side (cylindrical part) of a rotating disc-shaped grinding wheel, relative to a glass plate in which one surface is held by suction with a suction cup. In the grinding process, it is important that the glass plate on the suction surface of the suction cup held by the suction cup does not slip (does not deviate) due to the reaction force generated by "biting". The holding method of the suction cup is to obtain a friction force parallel to the glass surface (holding surface) by the pressure difference between the internal pressure of the suction cup and the external pressure to push the glass surface perpendicular to the holding surface. However, the area for holding the smaller glass for suction is itself smaller, so the friction force that can be obtained is also limited, and the problem of not being able to maintain the processing speed (forced processing causes the glass plate to shift and slip, resulting in the position of the glass plate deviating, so that the periphery cannot be ground into a specified shape as designed).

[0007] The object of the present invention is to provide a grinding system that can firmly fix the main body of a glass plate, and when grinding the periphery of the main body of the glass plate by biting into the side (cylindrical part) of a rotating disc-shaped grinding wheel of a grinding mechanism, it is possible to prevent the main body of the glass plate from sliding sideways (lateral deviation) while grinding the periphery of the main body. In addition, it is possible to provide a grinding system that can maintain the grinding speed and can grind the periphery of the glass plate into a specified shape according to the design. Technical means of solving problems

[0008] The present invention for solving the above-mentioned problems is based on a grinding system, which has: A grinding table is used to place the main body of the glass plate whose edge is broken by a predetermined breaking process; A worktable suction cup of a predetermined area is provided on the grinding worktable to suck and hold the lower surface of the main body of the glass plate; and Grinding mechanism; The peripheral edge of the main body of the glass plate mounted and fixed on the grinding table by the table suction cup is ground by the grinding mechanism.

[0009] The grinding system of the present invention based on the above premise is characterized in that: The grinding system has: A magnet is provided on the table suction cup and is located directly below the lower surface of the main body of the glass plate placed on the grinding table; and A magnetic weight component of a predetermined weight is located on the upper surface side of the main body of the glass plate and is attracted by a magnet; The grinding system includes: A first fixing unit, before the grinding process starts on the periphery of the main body of the glass plate, the table suction cup abuts against the lower surface of the main body of the glass plate and sucks and holds the lower surface of the main body; and The second fixing unit clamps the body portion by using a magnet located directly below the lower surface of the body portion and a magnetic weight member abutting against the upper surface of the body portion and attracted to the magnet before starting to grind the periphery of the body portion of the glass plate.

[0010] As an example of the present invention, a grinding system includes a magnetic weight member holding mechanism located on the upper surface side of a main body of a glass plate, The grinding system has: a first descending unit that, before starting to grind the periphery of the main body of the glass plate, lowers the magnetic hammer member toward the upper surface of the main body while the magnetic hammer member is held by the magnetic hammer member holding mechanism and places the magnetic hammer member just above the magnet in a manner that clamps the main body; and The first ascending unit, before starting to grind the periphery of the main body of the glass plate and after the first descending unit places the magnetic hammer component just above the magnet, releases the holding of the magnetic hammer component by the magnetic hammer component holding mechanism and ascends above the magnetic hammer component.

[0011] As another example of the present invention, the grinding system includes a positioning unit, which moves the magnetic hammer component holding mechanism in the forward and backward direction, and the magnetic hammer component held by the magnetic hammer component holding mechanism is located above the main body of the glass plate and in the center of the main body; In the first descending means, after the magnetic weight member is positioned above the main body of the glass plate and at the center of the main body by the positioning means, the magnetic weight member is descended toward the upper surface of the main body.

[0012] As another example of the present invention, a grinding system comprises: A second descending unit, after the grinding process of the periphery of the main body of the glass plate is completed, the magnetic hammer component holding mechanism descends toward the magnetic hammer component and holds the magnetic hammer component; The second ascending unit, after completing the grinding process on the periphery of the main body of the glass plate and after the magnetic hammer component holding mechanism holds the magnetic hammer component through the second descending unit, causes the magnetic hammer component holding mechanism to ascend upward from the upper surface of the main body of the glass plate while holding the magnetic hammer component, thereby releasing the adsorption of the magnetic hammer component to the magnet.

[0013] As another example of the present invention, the grinding system includes: A glass plate support that can move in the front-rear direction and the up-down direction and can move the main body of the glass plate that has been polished from the polishing workbench to the unloading area; and A bracket suction cup is arranged on the glass plate bracket and is adsorbed on the upper surface of the main body of the glass plate; The magnetic hammer component holding mechanism is provided on the glass plate support.

[0014] As another example of the present invention, the grinding system includes a lifting mechanism, which is disposed on a glass plate support and causes the magnetic hammer component holding mechanism to rise or fall independently; In the second lifting unit, the magnetic hammer component holding mechanism holding the magnetic hammer component is lifted by the lifting mechanism, thereby releasing the attraction of the magnetic hammer component to the magnet; The grinding processing system has a moving unit. In the moving unit, after the magnetic hammer component holding mechanism holding the magnetic hammer component is raised by the lifting mechanism, the glass plate bracket is moved in the front-rear direction so that the bracket suction cup is located above the main body of the glass plate. After the bracket suction cup is located above the main body, the glass plate bracket is lowered so that the bracket suction cup is adsorbed on the upper surface of the main body of the glass plate. After the bracket suction cup is adsorbed on the upper surface of the main body, the glass plate bracket is raised and moved forward at the same time, so that the main body of the glass plate is moved to the unloading area.

[0015] As another example of the present invention, the magnet has an adsorption surface of a predetermined area facing the lower surface of the main body of the glass plate; and the adsorption surface is located at the center of the table suction cup of the predetermined area.

[0016] As another example of the present invention, the magnet is a permanent magnet.

[0017] As another example of the present invention, a permanent magnet is covered with an iron cap to form a yoke for guiding magnetic flux.

[0018] As another example of the present invention, the magnetic weight member is made of any metal of iron, nickel, and cobalt, has a predetermined weight, and has a facing surface of a predetermined area facing the upper surface of the glass plate body. Effects of the Invention

[0019] According to the grinding processing system of the present invention, before the grinding processing of the periphery of the main body of the glass plate begins, the workbench suction cup abuts against and adsorbs the lower surface of the main body of the glass plate to hold the lower surface of the main body, and at the same time, before the grinding processing of the periphery of the main body of the glass plate begins, the main body is clamped by a magnet located directly below the lower surface of the main body and a magnetic hammer component abutting against the upper surface of the main body and adsorbed on the magnet. Therefore, not only is the main body of the glass plate placed and fixed on the grinding processing workbench with the help of the workbench suction cup, but the main body of the glass plate is also clamped with the help of the magnet and the magnetic hammer component adsorbed on the magnet, thereby strengthening the fixation of the main body of the glass plate to the grinding processing workbench. Even if the main body is a relatively small-sized (small-area) glass plate, the main body of the glass plate can be firmly fixed to the grinding processing workbench through the magnet and the magnetic hammer component together with the workbench suction cup. When the side surface (cylindrical part) of the rotating disc-shaped grinding wheel of the grinding mechanism is bitten into the peripheral edge grinding process of the main body of the glass plate, the grinding system can prevent the main body of the glass plate from sliding sideways (lateral deviation) on the grinding workbench, and can grind the peripheral edge of the main body while the main body of the glass plate is securely fixed on the grinding workbench. The grinding system can maintain the grinding speed and can complete the grinding of the glass plate into a specified shape according to the design.

[0020] In the grinding processing system, a magnetic hammer component holding mechanism is included, which is located on one side of the upper surface of the main body of the glass plate. Before the peripheral edge of the main body of the glass plate is ground, the magnetic hammer component is held by the magnetic hammer component holding mechanism, and the magnetic hammer component is placed directly above the magnet, so that the magnetic hammer component is lowered toward the upper surface of the main body and clamps the main body; before the peripheral edge of the main body of the glass plate is ground and after the magnetic hammer component is placed directly above the magnet, the magnetic hammer component holding mechanism releases the holding of the magnetic hammer component and rises above the magnetic hammer component, because the main body of the glass plate is ground at the beginning. Before grinding the periphery of the glass plate, the magnetic hammer component holding mechanism holding the magnetic hammer component descends toward the upper surface of the main body and places the magnetic hammer component directly above the magnet. After the magnetic hammer component is placed directly above the magnet, the magnetic hammer component holding mechanism releases the holding of the magnetic hammer component and rises above the magnetic hammer component, so that the main body of the glass plate can be reliably clamped by the magnet and the magnetic hammer component, and the fixation of the main body of the glass plate to the grinding workbench can be strengthened by the magnet and the magnetic hammer component. Even if the main body is a small-sized (small-area) glass plate, it can be firmly fixed to the grinding workbench. Because the fixation of the main body of the glass plate to the grinding workbench is strengthened by the magnet and the magnetic hammer component, even if the side (cylindrical part) of the rotating disc-shaped grinding wheel of the grinding mechanism bites into the periphery of the main body of the glass plate to grind the periphery of the main body of the glass plate, the main body of the glass plate will not slide sideways (deviate laterally) in the grinding workbench, and the periphery of the main body can be ground while the main body of the glass plate is reliably fixed to the grinding workbench.

[0021] In the grinding system, the magnetic hammer component holding mechanism is moved in the forward and backward directions, and the magnetic hammer component held by the magnetic hammer component holding mechanism is located above the main body of the glass plate and in the center of the main body. After the magnetic hammer component is located above the main body of the glass plate and in the center of the main body, the magnetic hammer component is lowered toward the upper surface of the main body. Because the magnetic hammer component is lowered to the center of the main body, the main body is clamped in the center of the main body by the magnet located just below the lower surface of the main body and the magnetic hammer component abutting against the upper surface of the main body and adsorbed on the magnet. Therefore, the center of the main body of the glass plate can be reliably clamped by the magnet and the magnetic hammer component, and the fixation of the main body of the glass plate to the grinding workbench can be strengthened by the magnet and the magnetic hammer component. Even if the main body is a relatively small-sized (small-area) glass plate, its main body can be firmly fixed to the grinding workbench.

[0022] In the grinding processing system, after the grinding processing of the peripheral edge of the main body of the glass plate is completed, the magnetic hammer component holding mechanism descends toward the magnetic hammer component and holds the magnetic hammer component. After the grinding processing of the peripheral edge of the main body of the glass plate is completed and the magnetic hammer component holding mechanism holds the magnetic hammer component, the magnetic hammer component holding mechanism rises upward from the upper surface of the main body of the glass plate while holding the magnetic hammer component, and releases the adsorption of the magnetic hammer component to the magnet. Because after the grinding processing of the peripheral edge of the main body of the glass plate is completed, the magnetic hammer component holding mechanism descending toward the upper surface of the main body of the glass plate holds the magnetic hammer component, and the magnetic hammer component holding mechanism holding the magnetic hammer component rises upward from the upper surface of the main body, and releases the adsorption of the magnetic hammer component to the magnet, it is possible to reliably release the clamping of the main body of the glass plate by the magnet and the magnetic hammer component, and the main body of the glass plate whose peripheral edge has been ground can be transported to the next unloading area (processing completion area). In the grinding system, after the grinding of the periphery of the main body of the glass plate is completed, the engagement of the magnet and the magnetic hammer component is released to transport the main body of the glass plate to the unloading area, and the main body of the next glass plate that has not been ground is placed and fixed on the grinding workbench, and the periphery of the main body is ground. Therefore, the main body of the glass plate can be continuously ground, and multiple glass plates can be effectively ground.

[0023] The grinding system includes: a glass plate support that can move in the forward and backward directions and the upward and downward directions to move the main body of the glass plate after the grinding process is completed from the grinding process table to the unloading area; a support suction cup arranged on the glass plate support and adsorbed on the upper surface of the main body of the glass plate; a magnetic hammer component holding mechanism arranged on the glass plate support; because before starting to grind the periphery of the main body of the glass plate, the magnetic hammer component holding mechanism arranged on the glass plate support descends toward the upper surface of the main body and places the magnetic hammer component directly above the magnet, and after the magnetic hammer component is placed directly above the magnet, the magnetic hammer component holding mechanism releases the holding of the magnetic hammer component and rises above the magnetic hammer component, so the main body of the glass plate can be reliably clamped by the magnet and the magnetic hammer component, and the fixation of the main body of the glass plate to the grinding process table can be strengthened by the magnet and the magnetic hammer component, and even if the main body is a small-sized (small-area) glass plate, its main body can be firmly fixed to the grinding process table. In the grinding processing system, after the grinding processing of the periphery of the main body of the glass plate is completed, the magnetic hammer component holding mechanism arranged on the glass plate bracket descends toward the upper surface of the main body of the glass plate and holds the magnetic hammer component. After holding the magnetic hammer component, the magnetic hammer component holding mechanism arranged on the glass plate bracket rises upward from the upper surface of the main body of the glass plate to release the adsorption of the magnetic hammer component on the magnet. Therefore, the clamping of the main body of the glass plate by the magnet and the magnetic hammer component can be reliably released, and the main body of the glass plate with the ground periphery can be transported to the next unloading area (processing completion area).

[0024] The grinding processing system includes: a lifting mechanism that is arranged on a glass plate support and causes a magnetic hammer component holding mechanism to rise or fall independently; the magnetic hammer component holding mechanism that holds the magnetic hammer component rises with the help of the lifting mechanism, thereby releasing the magnetic hammer component from adsorbing the magnet; after the magnetic hammer component holding mechanism that holds the magnetic hammer component rises with the help of the lifting mechanism, the glass plate support moves in the forward and backward directions so that the support suction cup is located above the main body of the glass plate, after the support suction cup is located above the main body, the glass plate support descends and the support suction cup is adsorbed on the upper surface of the main body of the glass plate, after the support suction cup is adsorbed on the upper surface of the main body, the glass plate support rises and moves forward at the same time, so that the main body of the glass plate is moved to the unloading area; because the glass plate support moves in a state where the support suction cup is adsorbed on the upper surface of the main body of the glass plate that has been completed with grinding processing, so that the main body of the glass plate that has completed grinding processing at the periphery can be continuously transported to the unloading area (processing completion area).

[0025] The grinding processing system includes: a magnet having an adsorption surface of a specified area opposite to the lower surface of the main body of the glass plate; the adsorption surface is located in the center of the workbench suction cup of the specified area; because not only the main body of the glass plate is placed and fixed on the grinding processing workbench by using the workbench suction cup, but also the main body of the glass plate is clamped by using the adsorption surface of the specified area through the magnet located in the center of the workbench suction cup and the magnetic hammer component adsorbed on the magnet, so the fixation of the main body of the glass plate to the grinding processing workbench can be strengthened by the magnet with the adsorption surface of the specified area and the magnetic hammer component, and the main body of the glass plate can be firmly fixed to the grinding processing workbench by the magnet with the adsorption surface of the specified area and the magnetic hammer component together with the workbench suction cup. When the grinding system grinds the periphery of the main body of a glass plate by biting into the side surface (cylindrical portion) of the rotating disc-shaped grinding wheel of the grinding mechanism, the magnet and magnetic material having an adsorption surface of a specified area together with the worktable suction cup can prevent the main body of the glass plate from sliding sideways (lateral deviation) on the grinding worktable, and can grind the periphery of the main body while the main body of the glass plate is securely fixed on the grinding worktable.

[0026] The grinding system in which the magnet is a permanent magnet is a system in which the main body of the glass plate is not only mounted and fixed on the grinding table by means of the table suction cup, but also the main body of the glass plate is clamped by means of the permanent magnet and the magnetic hammer component adsorbed on the permanent magnet, so that the fixation of the main body of the glass plate to the grinding table can be strengthened by the permanent magnet and the magnetic hammer component, and the main body of the glass plate can be firmly fixed to the grinding table by the permanent magnet and the magnetic hammer component together with the table suction cup. When the grinding system bites the side (cylindrical part) of the rotating disc-shaped grinding wheel of the grinding mechanism to grind the periphery of the main body of the glass plate, the permanent magnet and the magnetic hammer component together with the table suction cup can prevent the main body of the glass plate from sliding sideways (lateral deviation) on the grinding table, and the periphery of the main body can be ground while the main body of the glass plate is reliably fixed to the grinding table.

[0027] In the grinding processing system, the permanent magnet is covered with an iron cap to form a yoke for guiding the magnetic flux. The yoke for guiding the magnetic flux formed on the permanent magnet by the iron cap can increase the adsorption force of the permanent magnet. The main body of the glass plate can be clamped by the permanent magnet covered with the iron cap and the magnetic hammer component adsorbed on the permanent magnet, thereby strengthening the fixation of the main body of the glass plate to the grinding processing workbench. The permanent magnet covered with the iron cap and the magnetic hammer component together with the workbench suction cup can firmly fix the main body of the glass plate to the grinding processing workbench.

[0028] The grinding system includes: a magnetic hammer component made of any one of iron, nickel, and cobalt metals and having a specified weight, and the magnetic hammer component has an opposing surface of a specified area opposing the upper surface of the main body of the glass plate; because the magnetic hammer component is made of any one of iron, nickel, and cobalt metals, the magnetic hammer component is easily adsorbed on a magnet (permanent magnet or electromagnet), and the main body of the glass plate is clamped by using a magnet with an adsorption surface of a specified area located in the center of a suction cup and a magnetic hammer component of a specified weight adsorbed on the magnet. Therefore, the magnet with an adsorption surface of a specified area and the magnetic hammer component of a specified weight made of any one of nickel and cobalt metals can strengthen the fixation of the main body of the glass plate relative to the grinding workbench, and the main body of the glass plate can be firmly fixed to the grinding workbench through the magnet and the magnetic hammer component together with the workbench suction cup. When the grinding system grinds the periphery of the main body of a glass plate by biting into the side surface (cylindrical portion) of the rotating disc-shaped grinding wheel of the grinding mechanism, a magnet having an adsorption surface of a specified area and a magnetic hammer component of a specified weight made of either nickel or cobalt together with a suction cup can prevent the main body of the glass plate from sliding sideways (lateral deviation) on the grinding workbench, and can grind the periphery of the main body of the glass plate while the main body of the glass plate is securely fixed on the grinding workbench.

DETAILED DESCRIPTION

[0030] Referring to the side view of the glass sheet processing system 10 using the breaking system 10a, Figure 1The grinding system (grinding method) of the present invention is described in detail with reference to the accompanying drawings as follows. Figure 2 is a top view of a glass sheet processing system 10 using a grinding device 129 (grinding mechanism), Figure 3 It is a plan view showing an example of glass plates 11a and 11b which are processed by the breaking system 10a (glass plate processing system 10). Figure 3 1 shows the state where the glass plates 11a and 11b are positioned in the loading area 19. Figure 1 to Figure 3 In the figure, the front-back direction (X-axis direction) is indicated by arrow X, the width direction (Y-axis direction) is indicated by arrow Y, and the up-down direction (Z-axis direction) is indicated by arrow Z.

[0031] In the glass plate processing system 10, the glass plates 11a and 11b to be processed (the glass plates 11a and 11b before processing) are as follows: Figure 3 As shown, it has an upper surface 12 of a specified area and a lower surface 13 of a specified area, and has a specified thickness, and its plane shape is formed into a rectangle (quadrilateral) that is longer in the width direction. The glass plates 11a and 11b to be processed have a first side edge 14 (one side edge) and a second side edge 15 (the other side edge) that are separated and opposed in the width direction and extend in the front-to-back direction, a front edge 16 and a rear edge 17 that are separated and opposed in the front-to-back direction and extend in the width direction, and first to fourth corners 18a to 18d. In addition, sometimes the plane shape of the glass plate to be processed is formed into a polygon other than a rectangle (quadrilateral), and sometimes the edges of the glass plate are formed into curved arcs, and the shape of the glass plate includes all shapes.

[0032] The glass plate processing system 10 performs cutting, breaking, and grinding on glass plates 11a and 11b (plate-shaped glass) of different sizes, ranging from a large-sized (large-area) glass plate 11a with a larger area of ​​the upper surface 12 and the lower surface 13 to a small-sized (small-area) glass plate 11b with a smaller area of ​​the upper surface 12 and the lower surface 13. The glass plate processing system 10 is controlled by a controller (control device) (not shown).

[0033] The controller has a central processing unit (CPU or MPU) and memory (main memory and cache memory), and is a computer that works through an independent operating system (virtual OS), with a built-in large-capacity hard disk (large-capacity storage area). The controller is connected to input devices such as keyboards and numeric keypad units (not shown), and output devices such as monitors, displays, and touch panels (not shown).

[0034] In the controller's large-capacity hard disk (large-capacity storage area), the names and product numbers of the glass plates 11a and 11b to be processed, a plurality of coordinate data of the glass plates 11a and 11b that vary depending on the size (area) and shape of the glass plates 11a and 11b to be processed (coordinates of the side edges and the front and rear edges of the glass plates 11a and 11b, coordinates of the first to fourth corners 18a to 18d, coordinates of the center of the glass plates 11a and 11b, etc.), and image data of the glass plates 11a and 11b to be processed (plane image (six-sided image) and stereoscopic image (3D image)) are stored (saved) in a state associated with glass plate identification information (glass plate identification identifier) ​​that identifies the glass plates 11a and 11b. In addition to using the manufacturing serial number and serial number of the glass plates 11a and 11b, the controller may generate a unique identifier that identifies the glass plates 11a and 11b and use the generated identifier as the glass plate identification information.

[0035] The controller uses the coordinate data of the glass plates 11a and 11b stored in the large-capacity hard disk to perform NC control on the cutting device 65 (cutting mechanism), the breaking device 85 (breaking mechanism), and the grinding device 129 (grinding mechanism) described later in the cutting (cutting) processing area 20, the breaking processing in the breaking processing area 21, and the grinding processing in the grinding processing area 22. In the NC control, the controller digitizes the position where the processing (XY plane coordinates) is started and the position where the processing direction is changed according to the coordinates, and digitizes the movement direction, distance, and speed of the two axes of the X axis (front and back direction) and the Y axis (width direction). The signal after the command coordinates and axes are digitized is transmitted (input) to the cutting device 65, the breaking device 85, and the grinding device 129. In the NC control, by repeatedly performing "coordinates → axis → command", the shape to be processed is accurately expressed.

[0036] The glass plate processing system 10 includes: an inlet area 19 (processing start area) into which glass plates 11a and 11b to be processed (before processing) are placed, a carry-out area 23 (processing end area) from which the processed glass plates 11a and 11b are carried out, processing areas 20 to 22 arranged (installed) between the inlet area 19 and the carry-out area 23 for processing the glass plates 11a and 11b, and a conveying mechanism 24 that sequentially conveys the glass plates 11a and 11b to the inlet area 19 and the processing areas 20 to 22 and the carry-out area 23 from the rear (upstream) to the front (downstream) in the front-rear direction and moves the cutting device 65 and the grinding device 129 in the front-rear direction. The processing areas 20 to 22 are separated and opposed in the front-rear direction between the inlet area 19 and the carry-out area 23 and are arranged in the front-rear direction.

[0037] These processing areas 20 to 22 are formed by a cutting processing area 20 located in front of the front-to-back direction (downstream) of the carrying-in area 19 and separated forward by a predetermined dimension from the carrying-in area 19, a breaking processing area 21 located in front of the front-to-back direction (downstream) of the cutting processing area 20 and separated forward by a predetermined dimension from the cutting processing area 20, and a grinding processing area 22 located in front of the front-to-back direction (downstream) of the breaking processing area 21 and separated forward by a predetermined dimension from the breaking processing area 21. The cutting processing area 20, the breaking processing area 21, and the grinding processing area 22 are built on a system table 25 (machine table) formed into a quadrilateral that is long in the front-to-back direction.

[0038] The conveying mechanism 24 includes: a pair of first pillars 26a located at the rear of the system platform 25 and extending in the upward and downward directions, a pair of second pillars 26b located at the front of the system platform 25 and extending in the upward and downward directions, a fixed frame 27 located between the first and second pillars 26a, 26b and extending in the front-to-back direction, a first movable unit 28 (first movable unit) arranged on the side of one side of the fixed frame 27, and a second movable unit 29 (second movable unit) arranged at the lower part of the fixed frame 27.

[0039] The first moving unit 28 moves the cutting device 65 and the grinding device 129 forward and backward in the front-rear direction (X-axis direction) (linear movement). The first moving unit 28 is formed by a first guide frame 30, a pair of first guide rails 31, a first feed screw (ball screw) (not shown), a first running frame 32, a first slider (housing nut) (not shown), a pair of first guide shoes 33, and a first servo motor 34 (see Fig.14 ).

[0040] The first guide frame 30 is provided on the fixed frame 27 and extends in the front-rear direction. The first guide rails 31 are separated and opposed in the up-down direction, connected and fixed to the side of one side of the first guide frame 30 by a predetermined connection unit, and extend in the front-rear direction. The first feed screw (ball screw) is located between the first guide rails 31, rotatably supported by a plurality of bearings (not shown) fixed to the side of one side of the first guide frame 30, and extends in the front-rear direction.

[0041] The first running frame 32 is located on one side of the first guide frame 30 and extends in the front-rear direction. The first sliders (housing nuts) are arranged at predetermined intervals in the front-rear direction, and are connected and fixed to the opposing surface of the first running frame 32 that is opposite to the first guide frame 30 by predetermined connection means. The first guide shoes 33 are separated and opposed in the up-down direction, and are connected and fixed to the opposing surface of the first running frame 32 that is opposite to the first guide frame 30 by predetermined connection means, and extend in the front-rear direction.

[0042] The first servo motor 34 is located at the front end of the first guide frame 30 and is connected to the second support 26b through a bracket. The shaft of the first servo motor 34 is connected and fixed to the other end of the first feed screw. The rotation of the first servo motor 34 drives the first feed screw to rotate, and the rotation of the first feed screw causes the cutting device 65 and the grinding device 129 to move forward and backward (linearly move) in the forward and backward direction (X-axis direction).

[0043] When the shaft of the first servo motor 34 rotates in the counterclockwise direction, the first feed screw rotates in the counterclockwise direction, and the first slider moves from the front to the rear of the first guide frame 30 in the front-to-rear direction by the rotation of the first feed screw in the counterclockwise direction, and the first operating frame 32 moves from the front to the rear of the first guide frame 30 in the front-to-rear direction by the movement of the first slider. Conversely, when the shaft of the first servo motor 34 rotates in the clockwise direction, the first feed screw rotates in the clockwise direction, and the first slider moves from the rear to the front of the first guide frame 30 in the front-to-rear direction by the rotation of the first feed screw in the clockwise direction, and the first operating frame 32 moves from the rear to the front of the first guide frame 30 in the front-to-rear direction by the movement of the first slider.

[0044] The second moving unit 29 moves the first to fourth glass plate brackets 40a to 40d described later forward and backward (linearly). The second moving unit 29 is formed by a second guide frame 35, a pair of second guide rails 36, a second feed screw (ball screw) (not shown), a second running frame 37, a second slider (housing nut) (not shown), a pair of second guide shoes 38, a second servo motor 39, and the first to fourth glass plate brackets 40a to 40d (first to fourth glass plate lifters) (see FIG.

The second guide rails 36 are separated and opposed in the width direction, connected and fixed to the lower part of the second guide frame 35 by a predetermined connection unit, and extend in the front-rear direction. The second feed screw (ball screw) is located between the second guide rails 36, rotatably supported by a plurality of bearings (not shown) fixed to the lower part of the second guide frame 35, and extends in the front-rear direction.

[0046] The second running frame 37 is located at the lower part of the second guide frame 35 and extends in the front-rear direction. The second sliders (housing nuts) are arranged at predetermined intervals in the width direction, connected and fixed to the opposite surface of the second running frame 37 facing the second guide frame 35 by predetermined connection means. The second guide shoes 38 are separated and opposed in the width direction, connected and fixed to the opposite surface of the second running frame 37 facing the second guide frame 35 by predetermined connection means, and extend in the front-rear direction.

[0047] The second servo motor 39 is located at the rear end of the second guide frame 35 and is fixed to the fixed frame 27. The shaft of the second servo motor 39 is connected and fixed to the end of one side of the second feed screw through a timing belt (and / or a gear). The rotation of the second servo motor 39 drives the second feed screw to rotate, and the rotation of the second feed screw causes the first to fourth glass plate brackets 40a to 40d to move forward and backward (linearly move) in the front and rear direction (X-axis direction).

[0048] When the shaft of the second servo motor 39 rotates in the clockwise direction, the second feed screw rotates in the clockwise direction, and the second slider moves from the rear to the front of the second guide frame 35 in the front-to-back direction by the rotation of the second feed screw in the clockwise direction, and the second operating frame 37 (the first to fourth brackets 40a to 40d of the glass plate) moves from the rear to the front of the second guide frame 35 in the front-to-back direction by the movement of the second slider. On the contrary, when the shaft of the second servo motor 39 rotates in the counterclockwise direction, the second feed screw rotates in the counterclockwise direction, and the second slider moves from the front to the rear of the second guide frame 35 in the front-to-back direction by the rotation of the second feed screw in the counterclockwise direction, and the second operating frame 37 (the first to fourth brackets 40a to 40d of the glass plate) moves from the front to the rear of the second guide frame 35 in the front-to-back direction by the movement of the second slider. The control unit for controlling the start and stop, the number of rotations, and the rotation speed of the first and second servo motors 34 and 39 is connected to the controller via an interface (wired or wireless) (not shown).

[0049] The first to fourth glass plate brackets 40a to 40d are installed at the lower part of the second running frame 37, and extend downward from the running frame 37, and are arranged at equal intervals in the front-back direction. The first to fourth glass plate brackets 40a to 40d include: a pad setting plate 41, a bracket suction cup 42 (adsorption pad) provided at the center of the pad setting plate 41 and adsorbing and holding the upper surface 12 of the glass plates 11a and 11b, a vacuum mechanism (air suction device) (air vacuum pump) (not shown) that forms a negative pressure on the bracket suction cup 42 and applies an adsorption force to the bracket suction cup 42, and a bracket lifting mechanism (lifting mechanism) that raises or lowers the pad setting plate 41 (the bracket suction cup 42) in the vertical direction.

[0050] The bracket suction cup 42 (absorption pad) is made of a rubber material such as nitrile rubber or natural rubber, polyurethane rubber, and has a specified area. The bracket lifting mechanism is driven by a servo motor (not shown). The control unit that controls the start and stop of the vacuum mechanism (air vacuum pump) and the pad lifting mechanism (servo motor) is connected to the controller through an interface (wired or wireless) (not shown).

[0051] The first glass plate support 40a moves back and forth between the carrying-in area 19 and the cutting processing area 20, moves forward from the carrying-in area 19 to the cutting processing area 20, and moves backward from the cutting processing area 20 to the carrying-in area 19. In addition, the first glass plate support 40a moves back and forth in the vertical direction (rises or falls) between the carrying-in area 19 and the cutting processing area 20 by the support lifting mechanism. The second glass plate support 40b moves back and forth in the vertical direction between the cutting processing area 20 and the breaking processing area 21, moves forward from the cutting processing area 20 to the breaking processing area 21, and moves backward from the breaking processing area 21 to the cutting processing area 20. In addition, the second glass plate support 40b moves back and forth in the vertical direction (rises or falls) between the cutting processing area 20 and the breaking processing area 21 by the support lifting mechanism.

[0052] The third support 40c of the glass plate moves back and forth between the breaking process area 21 and the grinding process area 22 in the forward and backward direction, moves forward from the breaking process area 21 to the grinding process area 22, and moves backward from the grinding process area 22 to the breaking process area 21. In addition, the third support 40c of the glass plate moves back and forth in the upward and downward direction (rises or falls) between the breaking process area 21 and the grinding process area 22 by the support lifting mechanism. The fourth support 40d of the glass plate moves back and forth in the forward and backward direction between the grinding process area 22 and the unloading area 23, moves forward from the grinding process area 22 to the unloading area 23, and moves backward from the unloading area 23 to the grinding process area 22. In addition, the fourth support 40d of the glass plate moves back and forth in the upward and downward direction (rises or falls) between the grinding process area 22 and the unloading area 23 by the support lifting mechanism.

[0053] Figure 4 4 is a front view showing an example of a fourth glass plate support 40d. Figure 5 4 is a side view showing an example of a fourth glass plate bracket 40d. Figure 6 It is a plan view showing an example of the fourth glass plate holder 40d. Figure 5 The magnetic weight member 47 is shown in a state where it is placed at the center of the main body portion 66a of the glass plates 11a and 11b.

[0054] The fourth support 40d for the glass plate is provided with: a sliding rod 43 located approximately in the center thereof and extending in the front-rear direction; a magnetic hammer component holding mechanism 44 mounted on the sliding rod 43 and slidable (movable) in the front-rear direction; and a lifting mechanism 45 for raising or lowering only the magnetic hammer component holding mechanism 44 in the upward or downward direction. Figure 5 As shown, on the surface of the slide rod 43, a storage 46 extending in the front-rear direction is provided.

[0055] The magnetic hammer component holding mechanism 44 includes: a magnetic hammer component 47; a magnetic hammer component holding suction cup 49 having an adsorption holding surface 48 for adsorbing and holding the magnetic hammer component 47; a vacuum mechanism (air suction device) (air vacuum pump) (not shown) for forming a negative pressure on the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 and exerting an adsorption force on the magnetic hammer component holding suction cup 49; and a clamping mechanism (not shown) for fixing the magnetic hammer component holding mechanism 44 (magnetic hammer component holding suction cup 49) relative to the sliding rod 43 and releasing the fixing of the magnetic hammer component holding mechanism 44 (magnetic hammer component holding suction cup 49) relative to the sliding rod 43. An air cylinder is used in the lifting mechanism 45. A control unit for controlling the start and stop of the magnetic hammer component holding mechanism 44 (air vacuum pump) and the lifting mechanism 45 (air cylinder) is connected to the controller through an interface (wired or wireless) (not shown).

[0056] The magnetic hammer component 47 is a three-dimensional object formed in a hemispherical shape and having a specified volume, and has an adsorption surface 50 that can be detachably adsorbed on the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49, and an opposing surface 51 (pushing surface) located below the adsorption surface 50. The adsorption surface 50 protrudes upward from the opposing surface 51 (pushing surface) to draw an arc. The opposing surface 51 is a circular plane (flat surface) of a specified area that is flat in the horizontal direction. The magnetic hammer component 47 is made of any one of iron, nickel, and cobalt metals and has a specified weight. Approximately the entire area of ​​the adsorption surface 50 of the magnetic hammer component 47 is adsorbed and held on the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49. The weight of the magnetic hammer body 47 is in the range of 120 to 150 g, preferably in the range of 130 to 140 g.

[0057] The magnetic hammer component holding suction cup 49 is made of a rubber material such as nitrile rubber or natural rubber, polyurethane rubber, etc. The adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 protrudes upward to form a hemispherical shape. When the air vacuum pump is started, negative pressure is generated to generate adsorption force, and when the air vacuum pump is stopped, the adsorption force disappears. In the fourth bracket 40d of the glass plate, the handle connected to the clamping mechanism is rotated counterclockwise and the handle 52 is adjusted to the OFF position, which can release the fixation of the magnetic hammer component holding mechanism 44 (magnetic hammer component holding suction cup 49) relative to the sliding rod 43, and the magnetic hammer component holding mechanism 44 can slide (move) forward or backward along the sliding rod 43 in the front and rear direction.

[0058] In the fourth glass plate holder 40d, in order to place the magnetic hammer member 47 at the center of the main body 66a of the glass plates 11a and 11b, the position of the magnetic hammer member holding mechanism 44 (magnetic hammer member holding suction cup 49) relative to the slide rod 43 is adjusted according to the size (area) of the main body 66a of the glass plates 11a and 11b. The handle 52 is adjusted to the OFF position, and the magnetic hammer member holding mechanism 44 (magnetic hammer member holding suction cup 49) is slid (moved) forward or backward in the front-back direction. After the position of the magnetic hammer member holding mechanism 44 relative to the slide rod 43 is determined, the handle 52 is rotated counterclockwise and the handle 52 is adjusted to the ON position, and the magnetic hammer member holding mechanism 44 (magnetic hammer member holding suction cup 49) is fixed relative to the slide rod 43. In addition, once the position of the magnetic hammer member holding mechanism 44 (magnetic hammer member holding suction cup 49) relative to the slide rod 43 is adjusted, it will not be adjusted later unless the size (area) of the main body 66a is changed.

[0059] Figure 7 is a side view of the loading area 19, Figure 8 It is a top view of the loading area 19. Fig. 9 1 is a front view of the carrying-in area 19. The carrying-in area 19 has a carrying-in conveyor 53, a stopper 54 and a roller 55, a pair of roller lifting mechanisms 56, and a moving mechanism 57. The carrying-in area 19 is supported by legs (pillars) extending upward from the floor surface of the system table 25. In the carrying-in area 19, the first positioning unit (first positioning step) and the second positioning unit (second positioning step) are implemented to position the glass plates 11a and 11b moving toward the processing areas 20 to 22.

[0060] A first positioning reference L1 (virtual positioning first reference line) extending in the front-rear direction is set at the side edge portion 58a of one side of the loading area 19, and a second positioning reference L2 (virtual positioning second reference line) extending in the width direction is set. The first positioning reference L1 is a virtual line extending straightly in the front-rear direction based on the outermost edge of the first side edge 14 extending in the front-rear direction in one direction of the width direction of the large-sized (large-area) glass plate 11a (the glass plate 11a processed first) located on the outermost side in the width direction. The outermost edge, for example, is the vertex of the curve located on the outermost side in the width direction when the first side edge 14 (the side edge of one side) of the glass plates 11a and 11b is a curved arc. In addition, when the first side edge 14 (the side edge of one side) of the glass plates 11a and 11b extends straightly in the front-rear direction, the side edge 14 is the outermost edge.

[0061] The outermost edge located on the outermost side in the width direction of the first side edge 14 (the side edge on one side) extending in the front-rear direction in one direction of the width direction of the glass plates 11a and 11b is positioned at the first positioning reference L1. Positioning the outermost edge at the first positioning reference L1 means that, in addition to the case where the outermost edge is completely consistent with the first positioning reference L1, it also includes the case where the outermost edge is located near (close to) the inner side in the width direction of the first positioning reference L1, or the case where the outermost edge is located near (close to) the outer side in the width direction of the first positioning reference L1.

[0062] The front-to-back center O1 (center line L2 that divides the front-to-back dimension of the glass plates 11a and 11b into two and extends in the width direction) of the first side edge 14 (side edge on one side) extending in the front-to-back direction in one direction of the width direction of the glass plates 11a and 11b is positioned at the second positioning reference L2. Positioning the front-to-back center O1 (center line L2) at the second positioning reference L2 means that, in addition to the case where the front-to-back center O1 (center line L2) and the second positioning reference L2 are completely consistent, it also includes the case where the front-to-back center O1 (center line L2) is located near (close to) the front side of the second positioning reference L2 in the front-to-back direction, or the case where the front-to-back center O1 (center line L2) is located near (close to) the rear side of the second positioning reference L2 in the front-to-back direction.

[0063] The controller (glass plate processing system 10) calculates the width dimension of each glass plate 11a, 11b using the coordinate data of each glass plate 11a, 11b stored in the large-capacity hard disk, and determines the first movement dimension (first movement distance) in the width direction for positioning the first side edge 14 (side edge on one side) of the glass plates 11a, 11b at the first positioning reference L1 (virtual positioning first reference line) according to the difference in the calculated width dimension (Y-axis direction) of the glass plates 11a, 11b, and determines the number of rotations of the shaft of the third servo motor 51 described later (the number of rotations of the shaft for moving the glass plates 11a, 11b in the width direction by the first movement dimension (first movement distance)) according to the determined first movement dimension. The controller (glass plate processing system 10) stores (saves) the determined first movement dimension and the determined number of rotations of the shaft of the third servo motor 51 in the large-capacity hard disk in a state associated with the glass plate identification information (glass plate identification identifier) ​​of each glass plate 11a, 11b.

[0064] The controller (glass plate processing system 10) calculates the dimensions of the glass plates 11a and 11b in the front-rear direction (X-axis direction) using the coordinate data of the glass plates 11a and 11b stored in the large-capacity hard disk, and determines the second movement dimension for positioning the center O1 of the side edge 14 of one side of the glass plates 11a and 11b in the front-rear direction behind the second positioning reference L2 (virtual positioning second reference line) of the carrying conveyor 53 according to the difference in the calculated dimensions of the glass plates 11a and 11b in the front-rear direction. The controller (glass plate processing system 10) stores (saves) the determined second movement dimension in the large-capacity hard disk in a state associated with the glass plate identification information (glass plate identification identifier) ​​of each glass plate 11a and 11b.

[0065] The controller (glass plate processing system 10) calculates the moving dimensions (moving distances) of the cutting device 65 and the grinding device 129 in the front-to-back direction based on the calculated dimensions of the front-to-back direction of each glass plate 11a, 11b, and determines the number of rotations of the shaft of the first servo motor 34 (the number of rotations of the shaft that moves the cutting device 65 and the grinding device 129 in the front-to-back direction according to the moving dimensions (moving distance)) based on the calculated moving dimensions. The controller (glass plate processing system 10) stores (saves) the determined moving dimensions and the determined number of rotations of the shaft of the first servo motor 34 in a large-capacity hard disk in a state associated with the glass plate identification information (glass plate identification identifier) ​​of each glass plate 11a, 11b.

[0066] like Figure 7 to Figure 9 As shown, the loading conveyor 53 is a plurality of infinite tracks extending in the front-to-back direction (X direction), and is arranged at predetermined intervals in the width direction (Y direction). The control unit that controls the start and stop of these loading conveyors 53 and the conveying distance is connected to the controller through an interface (wired or wireless) (not shown). These loading conveyors 53 transport the glass plates 11a and 11b from the rear end (loading entrance) of the loading area 19 toward the front end (loading exit) from the rear to the front in the front-to-back direction. The stopper 54 is provided at the front end of the loading area 19 and is arranged at predetermined intervals in the width direction. The stopper 54 abuts against the front end edge 16 of the glass plates 11a and 11b that are moved forward from the rear end to the front end of the loading area 19 by these loading conveyors 53. A contact sensor (not shown) is provided on the stopper 54. The contact sensor is connected to the controller and detects the abutment (contact) of the front edge 16 of the glass plates 11 a and 11 b against the stopper 54 . When the front edge 16 abuts against the stopper 54 , the abutment signal is transmitted to the controller.

[0067] A plurality of these rollers 55 are rotatably mounted on a shaft 59 extending in the front-rear direction, or a plurality of these rollers 55 are mounted on the shaft 59 extending in the front-rear direction and rotate together with the shaft 59. The rollers 55 are arranged between the carrying-in conveyors 53 together with the shafts 59. The rollers 55 are arranged at predetermined intervals in the front-rear direction, and are arranged at predetermined intervals in the width direction. The rollers 55 rotate in the clockwise and counterclockwise directions toward the width direction, and abut against the lower surfaces 13 of the glass plates 11a and 11b, and hold the glass plates 11a and 11b so as to be movable in the width direction. The shafts 59 are mounted on a pedestal located below them through bearings.

[0068] A resistance plate (rubber ring) (not shown) is installed between the roller 55a among these rollers 55 and the shaft 59 to increase the rotational resistance of the roller 55a. The roller 55a increases the resistance with the shaft 59 through the resistance plate (rubber ring). If a rotational force exceeding the rotational resistance is not applied to the roller 55a, the roller 55a will not rotate, and the free rotation of the roller 55a will be blocked by the resistance plate. When the glass plates 11a and 11b are placed on these rollers 55, the free movement of the glass plates 11a and 11b in the width direction is blocked by the roller 55a with large rotational resistance. In addition, it is sufficient to install a resistance plate (rubber ring) between at least one of the rollers 55 and the shaft 59.

[0069] These roller lifting mechanisms 56 are arranged below the pedestal on which the shaft 59 is installed, and are separated and arranged in a predetermined size in the width direction. Air cylinders are used in these roller lifting mechanisms 56, and these shafts 59 and these rollers 55 are lifted and lowered in the vertical direction together with the pedestal through the roller lifting mechanisms 56 (air cylinders). The rising dimension and the falling dimension of the roller lifting mechanisms 56 (air cylinders) are set in advance. The control unit that controls the start and stop of these roller lifting mechanisms 56 (air cylinders) is connected to the controller through an interface (wired or wireless) (not shown). When the control unit of the roller lifting mechanism 56 (air cylinder) receives a lifting signal from the controller, the roller 55 (pedestal and shaft 59) is lifted and lowered by the roller lifting mechanism 56.

[0070] In addition, when the carrying-in conveyor 53 is conveying the glass plates 11a and 11b, the rollers 55 (base and shaft 59) are lowered to the bottom of the carrying-in conveyor 53 by the roller lifting mechanism 56 (cylinder), and the rollers 55 do not contact the lower surface 13 of the glass plates 11a and 11b. When the rollers 55 (base and shaft 59) are raised by the roller lifting mechanism 56 (cylinder), a part of the peripheral edge of the rollers 55 is exposed above the carrying-in conveyor 53, and the glass plates 11a and 11b are lifted to the top of the carrying-in conveyor 53 by the rollers 55.

[0071] The moving mechanism 57 includes: a rod 60 located above these loading conveyors 53 and these rollers 55, a third servo motor 61 arranged (built-in) in the rod 60, a feed screw (feed screw mechanism) (not shown) arranged (built-in) in the rod 60 and connected to the axis of the third servo motor 61, a moving arm 62 extending downward from the rod 60, and an abutment component 63 arranged at the lower end of the moving arm 62.

[0072] The rod 60 is installed behind the first support 26a and extends in the width direction. The movable arm 62 is movably provided on the feed screw, and the feed screw is rotated by the rotation of the shaft of the third servo motor 61, and the movable arm 62 moves linearly in one direction and the other direction in the width direction along the rod 60. As the movable arm 62 moves in the width direction, the contact member 63 moves linearly in one direction and the other direction in the width direction together with the movable arm 62. In a state where the roller 55 raised by the roller lifting mechanism 56 (cylinder) abuts against the lower surface 13 of the glass plates 11a and 11b, the contact member 63 abuts against the other side edge 15 of the glass plates 11a and 11b, so as to push the glass plates 11a and 11b in the width direction in a manner that the glass plates 11a and 11b move in the width direction. The control unit that controls the start and stop of the third servo motor 61 and the number of rotations and the rotation speed is connected to the controller through an interface (wired or wireless) (not shown).

[0074] The cutting processing area 20 includes: a cutting processing workbench 64 (cutting processing table) for placing the glass plates 11a and 11b positioned in the carrying-in area 19, and a cutting device 65 (cutting device) for cutting the edge 66b (peripheral edge) of the glass plates 11a and 11b placed on the cutting processing workbench 64 along an outer shape cutting line K1 (cutting line).

[0075] The cutting workbench 64 is installed on a base rail 67a which is fixed to the floor surface of the system table 25 and is long in the width direction. The cutting workbench 64 is moved in the width direction by the first moving mechanism 68a while the positioned glass plates 11a and 11b are placed thereon. The first moving mechanism 68a is formed by a running guide rail 69a, a feed screw 70a (ball screw), a fourth servo motor 71, a guide shoe 72a, and a slider 73a (housing nut).

[0076] These running rails 69a are arranged on the upper surface of the base rail 67a and extend in the width direction. The feed screw 70a (ball screw) is arranged on the upper surface of the base rail 67a and on the side of the running rail 69a and extends in the width direction. The fourth servo motor 71 is arranged on the base rail 67a and moves the cutting processing table 64 back and forth in the width direction. The other end of the feed screw 70a is connected to the shaft of the fourth servo motor 71.

[0077] The feed screw 70a is rotatably supported by a bearing (not shown) fixed to the base rail 67a. The guide shoe 72a is mounted on the lower surface of the plunge processing table 64 and extends in the width direction. The guide shoe 72a is slidably engaged with the running guide rail 69a. The slider 73a (housing nut) is mounted on the lower surface of the plunge processing table 64 and between the guide shoe 72a. The slider 73a is rotatably screwed to the feed screw 70a.

[0078] When the shaft of the fourth servo motor 71 rotates in the clockwise direction, the feed screw 70a rotates in the clockwise direction. Through the clockwise rotation of the feed screw 70a, the slider 73a moves from the second side edge portion 58b (the other side edge portion) of the cutting-in processing area 20 toward the first side edge portion 58a (the side edge portion of one side), so that the feed screw 70a moves in the width direction. At the same time, through the movement of the slider 73a, the cutting-in processing worktable 64 moves in the width direction from the second side edge portion 58b of the cutting-in processing area 20 toward the first side edge portion 58a. On the contrary, when the shaft of the fourth servo motor 71 rotates in the counterclockwise direction, the feed screw 70a rotates in the counterclockwise direction. Through the counterclockwise rotation of the feed screw 70a, the slider 73a moves from the first side edge 58a (the side edge on one side) of the cutting-in processing area 20 toward the second side edge 58b (the side edge on the other side), so that the feed screw 70a moves in the width direction. At the same time, through the movement of the slider 73a, the cutting-in processing worktable 64 moves in the width direction from the first side edge 58a of the cutting-in processing area 20 toward the second side edge 58b.

[0079] The cutting device 65 includes a cutting fixture 74, a cylinder 75, and a fifth servo motor 76. The cutting fixture 74 is formed by a cutting cutter wheel 77, a cutting cutter support 78 (cutting support), a cutter lifting shaft 79, and a cutter lifting guide 80. The cutting cutter wheel 77 is connected to the cutting cutter support 78 through a bearing (not shown) and is freely rotatable along the axis of the intervening bearing. The cutting cutter wheel 77 forms an outer shape cutting line K1 at the edge 66b (peripheral portion) of the glass plates 11a and 11b.

[0080] The cutting knife support 78 is located directly above the cutting knife wheel 77 and is connected to the cutting knife wheel 77, and supports the cutting knife wheel 77. The cutting knife lifting shaft 79 is located directly above the cutting knife support 78 and is connected to the cutting knife support 78, and supports the cutting knife support 78. The cutting knife lifting guide 80 is located directly above the cutting knife lifting shaft 79 and is connected to the cutting knife lifting shaft 79, and supports the cutting knife lifting shaft 79. The cutting fixture 74 (including the cylinder 75) is located directly above the cylinder 75 and is connected to a support shaft 81 that rotatably supports the cutting fixture 74. The support shaft 81 is mounted on a bracket 82 located directly above it. The bracket 82 (cutting device 65) is connected to the first moving unit 28 of the aforementioned conveying mechanism 24 that moves forward and backward (linearly moves) in the forward and backward direction (X-axis direction).

[0081] The air cylinder 75 is provided just above the cutter lifting shaft 79. The air cylinder 75 raises and lowers (moves up and down) the cutting cutter wheel 77 (cutting cutter support 78) in the vertical direction (Z-axis direction), and when the outer shape cutting line K1 (cutting line) is formed on the edge 66b of the glass plates 11a and 11b, the cutting cutter wheel 77 is lowered toward the upper surface 12 of the glass plates 11a and 11b, and a cutting pressure (a downward pushing force) is applied (applied) to the cutting cutter wheel 77. The shaft of the fifth servo motor 76 is connected to the support shaft 81 through a timing belt 83. The fifth servo motor 76 adjusts the direction of the cutting direction (the angle around the axis perpendicular to the XY plane) of the cutting fixture 74 (cutting cutter wheel 77).

[0082] In the cutting device 65, the control unit of the fifth servo motor 76 rotates the shaft of the motor 76 according to the NC control information transmitted by the controller, and performs NC control on the cutting fixture 74 (cutting cutter wheel 77), and forms (cuts) the outer shape cutting line K1 (cutting line) of the desired shape at the edge 66b (peripheral portion) of the glass plate 11a, 11b according to the NC control. The control unit that controls the start and stop of the fourth and fifth servo motors 71, 76 and the number of rotations and the rotation speed is connected to the controller through an interface (wired or wireless) (not shown).

[0083] Fig.16 FIG. 8 is a top view of the breaking processing table 84. Fig.172 is a side view of the breaking workbench 84. The breaking area 21 includes: a breaking workbench 84 (breaking workbench) on which the glass sheets 11a and 11b positioned in the loading area 19 and cut in the cutting area 20 are placed, and a breaking device 85 (see FIG. 2 ) for breaking the edge 66b (peripheral edge) placed on the breaking workbench 84 and located outside the outer shape cutting line K1 (cutting line) of the glass sheets 11a and 11b. Figure 18 to Figure 24 ), a supporting device 86 for supporting the glass plates 11a and 11b (see Fig.25 , Fig.26 ).

[0084] The breaking table 84 is formed by a belt conveyor 87 running in the width direction (Y-axis direction) and a conveyor drive motor 88 for driving the belt conveyor 87, and is provided on a base fixed to the floor surface of the system table 25. The belt conveyor 87 is formed by a belt 89 extending in the width direction, a plurality of pulleys 90 and rollers 91 supporting the belt 89, and a conveyor frame 92 supporting the belt 89, the pulleys 90, and the rollers 91. The glass plates 11a and 11b after the cutting process are placed on the belt conveyor 87. The belt conveyor 87 conveys the edge 66b of the glass plates 11a and 11b broken by the breaking device 85 to the other side in the width direction (from the first side edge 58a to the second side edge 58b), and discards the broken edge 66b of the glass plates 11a and 11b in a trash box (not shown).

[0085] The shaft of the conveyor drive motor 88 is connected to the pulley 90 through a synchronous belt. The control unit that controls the start and stop of the conveyor drive motor 88 is connected to the controller through an interface (wired or wireless) (not shown). The rotation speed of the shaft of the conveyor drive motor 88 (the running speed of the belt) is set in advance, and the state of the rotation speed (the running speed of the belt) associated with the specific information of the conveyor drive motor 88 is stored (saved) in the large-capacity hard disk of the controller. When the control unit of the conveyor drive motor 88 receives a drive signal from the controller, the conveyor drive motor 88 is driven at a specified number of rotations. When the controller receives a stop signal, the drive of the conveyor drive motor 88 is stopped. When the shaft of the conveyor drive motor 88 rotates in the clockwise direction, the rotation is transmitted to the pulley 90 through the synchronous belt, and the pulley 90 rotates in the clockwise direction. The rotation of the pulley 90 causes the belt 89 to run in the other direction of the width direction.

Fig. 20 is a top view of the breaking device 85, Fig.21 , 22 It is an enlarged front view of the breaking device 85. Fig.23It is a partial cross-sectional side view of the first and second breaking fixtures 94a and 94b. Fig.24 It is a front view of the first and second breaking jigs 94a and 94b. Fig.21 The breaking cutter wheel 103 is shown in a state where the first and second pressing members 105a and 105b are raised. Fig. 22 The breaking cutter wheel 103 is shown in a state where the first and second pressing members 105a and 105b are lowered.

[0087] The breaking device 85 is formed of two first breaking devices 85a and second breaking devices 85b separated in the width direction. The first breaking device 85a is connected to the first guide frame 30, and the second breaking device 85b is connected to the suspension frame 93. The suspension frame 83 is connected to the side of the second guide frame 35. The first breaking device 85a includes: a first breaking fixture 94a (breaking fixture), a sixth servo motor 95 (X-axis servo motor) and an X-axis first actuator 96a, a seventh servo motor 97 (Y-axis servo motor) and a Y-axis first actuator 98a, an X-axis first actuator frame 99a and a Y-axis first actuator frame 99c. The X-axis first actuator frame 99a and the Y-axis first actuator frame 99c are connected in series at one end thereof.

[0088] The second breaking device 85b includes a second breaking jig 94b (breaking jig), an eighth servo motor 100 (X-axis servo motor) and an X-axis second actuator 96b, a ninth servo motor 101 (Y-axis servo motor) and a Y-axis second actuator 98b, a second actuator frame 98b, an X-axis second actuator frame 99b and a Y-axis second actuator frame 99d. The X-axis second actuator frame 99b and the Y-axis second actuator frame 99d are connected in series at one end thereof.

[0089] like Fig.21 , 22 As shown, the first and second breaking clamps 94a, 94b of the first and second breaking devices 85a, 85b are formed by a breaking cutter bracket 102, a breaking cutter wheel 103, a bracket lifting mechanism 104 (first lifting mechanism), a first pushing component 105a that pushes downward the main body 66a of the glass plates 11a, 11b forming the outer shape cutting line K1 (cutting line) and the end tangent line K2 (the glass plates 11a, 11b extending to the inner side of the outer shape cutting line K1), a second pushing component 105b that pushes downward the edge 66b of the glass plates 11a, 11b forming the outer shape cutting line K1 (cutting line) and the end tangent line K2 (the glass plates 11a, 11b extending to the outer side of the outer shape cutting line K1), a first pushing component lifting mechanism 106a (second lifting mechanism), and a second pushing component lifting mechanism 106b (third lifting mechanism).

[0090] The breaking cutter support 102 is located above the breaking cutter wheel 103 and supports the breaking cutter wheel 103. Fig.23 , 24 As shown, the breaking blade holder 102 includes a holder body 107 having a connection portion and a holder head 108 attached to the front end of the holder body 107 .

[0091] The breaking cutter wheel 103 forms (cuts) an end tangent line K2 (scoring line) at the edge 66b of the glass plates 11a and 11b to be processed (the edge 66b of the glass plates 11a and 11b extending to the outside of the outer cut-out line K1). The breaking cutter wheel 103 is rotatably (rollingly) mounted on the front end of the support head 108 via a rolling shaft 111, and its peripheral edge 112 rolls around the rolling shaft 111. The breaking cutter wheel 103's cutting wheel axis O3 extending in the vertical direction is eccentric (deviation) radially outward relative to the cutting knife support center axis O2 extending in the vertical direction of the breaking cutter support 102 (support body 107). The separation dimension S (eccentricity dimension) of the cutting wheel axis O3 in the width direction relative to the cutting knife support center axis O2 is in the range of 0.5 to 2 mm.

[0092] The bracket head 108 is connected to the bracket body 107 through the bearing 110, and is freely rotatable along the axis of the bearing 110 located therebetween, and can rotate 360° in the direction (θ direction) around the cutter bracket center axis O2 of the breaking cutter bracket 102. The bracket head 108 rotates in the clockwise direction and the counterclockwise direction around the cutter bracket center axis O2. The rotation of the bracket head 108 can cause the breaking cutter wheel 103 (breaking cutter wheel 103 having a cutter wheel axis O3 eccentric to the cutter bracket center axis O2) to rotate 360° in the direction around the cutter wheel axis O3 relative to the breaking cutter bracket 102. The breaking cutter wheel 103 rotates in the clockwise direction and the counterclockwise direction around the cutter bracket center axis O2.

[0093] Because the cutting wheel axis O3 of the breaking cutting wheel 103 is radially eccentric to the outside relative to the center axis O2 of the cutting knife holder, when the first and second breaking clamps 94a, 94b (breaking cutting knife holder 102) operate (move) in a specified direction on the upper surface 12 of the glass plates 11a, 11b, the rolling (moving) direction of the peripheral edge 112 of the breaking cutting wheel 103 exerts a caster effect toward the operating (moving) direction (extension direction of the virtual end tangent) of the first and second breaking clamps 94a, 94b (breaking cutting knife holder 102).

[0094] The support lifting mechanism 104 (first lifting mechanism) is provided directly above the support body 107 and is connected to the connection portion 113 of the breaking cutter support 102 (support body 107). The support lifting mechanism 104 is fixed to the bracket 114 by means of a fixing member. The support lifting mechanism 104 (first lifting mechanism) uses an air cylinder. The support lifting mechanism 104 (air cylinder) lifts (moves up and down) the breaking cutter support 102 (breaking cutter wheel 103) of the first and second breaking jigs 94a and 94b in the up-down direction (Z-axis direction). When the edge 66b of the glass plates 11a and 11b is broken, the support lifting mechanism 104 (air cylinder) lowers the breaking cutter wheel 103 toward the upper surface 12 of the glass plates 11a and 11b, and applies (applies) an end cutting pressure (a downward pushing force) to the cutter wheel 103. The rising dimension and the falling dimension of the support device lifting mechanism are set in advance.

[0095] The first pushing member 105a is made of rubber or synthetic resin having rubber elasticity. The first pushing member 105a is located near the outer side of the second pushing member 105b and extends in the peripheral direction of the second pushing member 105b. The first pushing member 105a has a first pushing surface 115a of a predetermined area that abuts against the upper surface 12 of the glass plates 11a and 11b. The first pushing surface 115a is formed into a semicircular ring shape surrounding the second pushing member 105b.

[0096] The first pushing member lifting mechanism 106a (second lifting mechanism) is located on the side of the first pushing member 105a in the width direction and is fixed to the bracket 114 by a fixing member. The first pushing member lifting mechanism 106a (second lifting mechanism) uses a cylinder. The first pushing member lifting mechanism 106a (cylinder) lifts (moves up and down) the first pushing member 105a of the first and second breaking jigs 94a and 94b in the vertical direction (Z-axis direction).

[0097] When the edge 66b of the glass plates 11a and 11b is broken, the first push member lifting mechanism 106a (second lifting mechanism) lowers the first push member 105a toward the upper surface 12 of the glass plates 11a and 11b, and applies (applies) a downward push force to the first push member 105a. The rising dimension and the falling dimension of the first push member 105a are set in advance. The bracket 114 on one side is slidably mounted on the X-axis first actuator frame 99a and the Y-axis first actuator frame 99c.

[0098] The second pushing member 105b is made of rubber or synthetic resin having rubber elasticity.

The second pushing member 105b has a second pushing surface 115b of a predetermined area that abuts against the upper surface 12 of the glass plates 11a and 11b. The second pushing surface 115b is formed into a circular ring shape surrounding the breaking cutter wheel 103. A through hole 116 is formed in the center of the second pushing member 105b in the up-down direction.

[0099] The second pushing member lifting mechanism 106b (third lifting mechanism) is located on the side of the second pushing member 105b in the width direction and is fixed to the bracket 114 by a fixing member. The second pushing member lifting mechanism 106b uses a cylinder. The second pushing member lifting mechanism 106b (cylinder) lifts (moves up and down) the second pushing member 105b of the first and second breaking jigs 94a and 94b in the vertical direction (Z-axis direction). When the edge 66b of the glass plates 11a and 11b is broken, the second pushing member lifting mechanism 106a (third lifting mechanism) lowers the second pushing member 105b toward the upper surface 12 of the glass plates 11a and 11b, and applies (applies) a pushing force downward to the second pushing member 105b. The lifting dimension and the lowering dimension of the second pushing member 105b are set in advance. The bracket 114 on the other side is slidably mounted on the X-axis second actuator frame 99b and the Y-axis second actuator frame 99d. The control unit for controlling the start and stop of the bracket lifting mechanism 104 (first lifting mechanism), the control unit for controlling the start and stop of the first pushing component lifting mechanism 106a (second lifting mechanism), and the control unit for controlling the start and stop of the second pushing component lifting mechanism 106b (third lifting mechanism) are connected to the controller via an interface (wired or wireless) (not shown).

When the shaft of the sixth servo motor 95 rotates in the counterclockwise direction, the screw portion of the X-axis first actuator 96a rotates in the counterclockwise direction. When the screw portion rotates in the counterclockwise direction, the breaking fixture 94a of the first breaking device 85a moves backward along the X-axis first actuator frame 99a in the front-rear direction together with the bracket 114.

When the shaft of the seventh servo motor 97 rotates in the clockwise direction, the screw portion of the Y-axis first actuator 98a rotates in the clockwise direction. When the screw portion rotates in the clockwise direction, the first breaking fixture 94a of the first breaking device 85a moves along the Y-axis first actuator frame 99c toward one side in the width direction together with the bracket 114. When the shaft of the seventh servo motor 97 rotates in the counterclockwise direction, the screw portion of the Y-axis first actuator 98a rotates in the counterclockwise direction. When the screw portion rotates in the counterclockwise direction, the first breaking fixture 94a of the first breaking device 85a moves along the Y-axis first actuator frame 99c toward the other side in the width direction together with the bracket 114. The control unit that controls the start and stop, rotation number, and rotation speed of the sixth and seventh servomotors 95 and 97 is connected to the controller via an interface (wired or wireless) (not shown).

[0102] The eighth servo motor 110 (X-axis servo motor) is arranged on the X-axis second actuator frame 99b, and its shaft is connected to the X-axis second actuator 96b. The X-axis second actuator 96b has a screw portion and a guide portion (not shown). When the shaft of the eighth servo motor 110 rotates in the clockwise direction, the screw portion of the X-axis second actuator 96b rotates in the clockwise direction. When the screw portion rotates in the clockwise direction, the second breaking fixture 94b of the second breaking device 85b moves forward along the X-axis second actuator frame 99b together with the bracket 114 in the front-rear direction. When the shaft of the eighth servo motor 110 rotates in the counterclockwise direction, the screw portion of the X-axis second actuator 96b rotates in the counterclockwise direction. When the screw portion rotates in the counterclockwise direction, the second breaking fixture 94b of the second breaking device 85b moves backward along the X-axis second actuator 89b in the front-rear direction together with the bracket 114.

The second support member lifting mechanism 119 (cylinder) lifts (moves up and down) the second support member 118b of the first and second support devices 86a and 86b in the up-down direction (Z-axis direction). When the edge 66b of the glass plates 11a and 11b is broken, the second support member lifting mechanism 119 (fourth lifting mechanism) lowers the second support member 118b from the lower surface 13 of the glass plates 11a and 11b to form a gap between the lower surface 13 of the glass plates 11a and 11b and the second support surface 127b (a step is formed between the first support surface 127a and the second support surface 127b). The lowering dimension of the second support member 118b is set in advance.

The Y-axis fourth actuator 123b has a screw portion and a guide portion (not shown). When the shaft of the thirteenth servo motor 126 rotates in the clockwise direction, the screw portion of the Y-axis fourth actuator 123b rotates in the clockwise direction. When the screw portion rotates in the clockwise direction, the second support device 86b moves along the Y-axis fourth actuator frame 124d toward one side of the width direction together with the guide frame 117. When the shaft of the thirteenth servo motor 126 rotates in the counterclockwise direction, the screw portion of the Y-axis fourth actuator 123b rotates in the counterclockwise direction. When the screw portion rotates in the counterclockwise direction, the second support device 86b moves along the Y-axis fourth actuator frame 124d toward the other side of the width direction together with the guide frame 117. In addition, the second support device 86b and the second breaking device 85b (second breaking fixture 94b) move synchronously in the front-rear direction and the width direction (horizontal direction). The control unit that controls the start and stop of the twelfth and thirteenth servo motors 125 and 126 and the number of rotations and the rotation speed is connected to the controller through an interface (wired or wireless) (not shown).

[0114] Fig. 27 2 is a front view of a grinding device 129 disclosed as an example and arranged in the grinding processing area 22. Fig.28 It is a side view of the grinding device 129. Fig.29 It is a top view of the grinding device 129. The grinding processing area 22 includes: a grinding processing table 128 (grinding processing table) on which the glass plates 11a and 11b which have been positioned in the carrying-in area 19 and have been cut in the cutting processing area 20 and broken in the breaking processing area 21 are placed, and a grinding device 129 (grinding mechanism) for grinding the edge (peripheral edge) of the main body 66a of the glass plates 11a and 11b placed on the grinding processing table 128.

[0115] The grinding workbench 128 is installed on the base rail 67b which is fixed to the floor surface of the system table 25 and is long in the width direction (refer to Fig.10 The grinding workbench 128 is provided with a workbench suction cup 130 (suction pad) for sucking and holding the glass plates 11a and 11b, a magnet 131 located directly below the workbench suction cup 130, a support column 132 for supporting the workbench suction cup 130, and a vacuum mechanism (air suction device) (air vacuum pump) (not shown) for forming a negative pressure on the workbench suction cup 130 and applying suction force to the workbench suction cup 130. The control unit for controlling the start and stop of the vacuum mechanism is connected to the controller via an interface (wired or wireless) (not shown).

[0116] The workbench suction cup 130 (adsorption pad) is detachably connected and fixed to the upper part of the pillar 132 through a prescribed connection unit. The workbench suction cup 130 is made of a rubber material such as nitrile rubber, natural rubber, polyurethane rubber, etc., and has a prescribed area. The magnet 131 is detachably connected and fixed to the upper part of the pillar 132, that is, the central part of the pillar 132, through a prescribed connection unit. The magnet 131 has an adsorption surface 134 of a prescribed area, and the adsorption surface 134 is located directly below the center 133 of the workbench suction cup 130 of a prescribed area. The adsorption surface 134 is a circular plane (flat surface) that is flat in the horizontal direction.

[0117] In magnet 131, a cylindrical permanent magnet that is longer in the up-down direction is used. The permanent magnet can utilize ferrite magnets, alloy magnets such as aluminum nickel cobalt magnets and iron chromium cobalt magnets, and rare earth magnets such as neodymium magnets and samarium cobalt magnets. Although not shown in the figure, the permanent magnet (magnet 131) is covered with an iron cap to form a yoke for guiding the magnetic flux. The yoke for guiding the magnetic flux is formed on the permanent magnet by the iron cap, thereby increasing the adsorption force of the permanent magnet (magnet 131). It should be noted that the permanent magnet (magnet 131) does not need to be covered with an iron cap, and the permanent magnet (magnet 131) does not need to have a yoke formed thereon.

[0118] The magnet 131 may also be an electromagnet. The electromagnet is covered with an iron cap to form a yoke for guiding the magnetic flux. The iron cap forms a yoke for guiding the magnetic flux on the electromagnet (magnet 131), thereby increasing the adsorption force of the electromagnet (magnet 131). It should be noted that the electromagnet (magnet 131) may not be covered with an iron cap, and the electromagnet (magnet 131) may not have a yoke formed thereon.

[0119] The electromagnet (magnet 131) is powered (energized) by a DC power supply (not shown). The control unit that controls the power supply (energization) of the electromagnet (magnet 131) is connected to the controller through an interface (wired or wireless) (not shown). The support 132 is formed into a cylindrical shape that is long in the vertical direction, and its lower end is detachably connected and fixed to the grinding workbench 128 through a prescribed connection unit. A connection joint 135 (threaded joint) connected to a vacuum mechanism (air suction device) (air vacuum pump) is installed on the upper side of the support 132.

[0120] The grinding table 128 is moved in the width direction by the second moving mechanism 68b while the positioned glass plates 11a and 11b are placed thereon. In addition, as the grinding table 128 moves, the support 132 (table suction cup 130) connected and fixed to the grinding table 128 moves in the width direction. The second moving mechanism 68b is formed by a running guide rail 69b, a feed screw 70b (ball screw), a fourteenth servo motor 136, a guide shoe 72b, and a slider 73b (housing nut).

[0121] These running rails 69b are arranged on the upper surface of the base rail 67b and extend in the width direction. The feed screw 70b (ball screw) is arranged on the upper surface of the base rail 67b and on the side of the running rail 69b and extends in the width direction. The fourteenth servo motor 136 is arranged on the base rail 67b to move the grinding table 128 back and forth in the width direction. The other end of the feed screw 70b is connected to the shaft of the fourteenth servo motor 136.

[0122] The control unit for controlling the start and stop, rotation number, and rotation speed of the fourteenth servo motor 136 is connected to the controller via an interface (wired or wireless) (not shown). When the control unit of the fourteenth servo motor 136 receives a driving signal from the controller, it drives the fourteenth servo motor 136 at a specified rotation number and rotation speed, and when it receives a stop signal from the controller, it stops driving the fourteenth servo motor 136.

[0123] The feed screw 70b is rotatably supported by a bearing (not shown) fixed to the base rail 67b. The guide shoe 72b is mounted on the lower surface of the grinding table 128 and extends in the width direction. The guide shoe 72b is slidably engaged with the running guide rail 69b. The slider 73b (housing nut) is mounted on the lower surface of the grinding table 128 and between the guide shoe 72b. The slider 73b is rotatably screwed to the feed screw 70b.

[0124] When the shaft of the fourteenth servo motor 136 rotates in the clockwise direction, the feed screw 70b rotates in the clockwise direction. Through the clockwise rotation of the feed screw 70b, the slider 73b moves from the side edge 58b on the other side of the grinding processing area 22 toward the side edge 58a on one side, so that the feed screw 70b moves in the width direction. At the same time, through the movement of the slider 73b, the grinding processing worktable 128 (worktable suction cup 130) moves in the width direction from the side edge 58b on the other side of the grinding processing area 22 toward the side edge 58a on one side.

[0125] When the shaft of the fourteenth servo motor 136 rotates in the counterclockwise direction, the feed screw 70b rotates in the counterclockwise direction. Through the counterclockwise rotation of the feed screw 70b, the slider 73b moves from the side edge 58a on one side of the grinding processing area 22 toward the side edge 58b on the other side, so that the feed screw 70b moves in the width direction. At the same time, through the movement of the slider 73b, the grinding processing worktable 128 (worktable suction cup 130) moves in the width direction from the side edge 58a on one side of the grinding processing area 22 toward the side edge 58b on the other side.

[0126] In addition, the fourteenth servo motor 136 is synchronously driven with the fourth servo motor 71 of the cutting process area 20, and synchronously moves from the side edge 58b of the cutting process table 64 on the other side of the cutting process area 20 to the side edge 58a of one side, and the grinding process table 128 moves from the side edge 58b of the grinding process area 22 to the side edge 58a of one side. Alternatively, the cutting process table 64 moves from the side edge 58a of the cutting process area 20 on one side to the side edge 58b of the other side, and the grinding process table 128 (table suction cup 130) moves from the side edge 58a of the grinding process area 22 to the side edge 58b of the other side. The control unit that controls the start and stop of the fourteenth servo motor 136 and the number of rotations and the rotation speed is connected to the controller through an interface (wired or wireless) (not shown).

[0127] The grinding device 129 (grinding mechanism) includes a grinding jig 137, a fifteenth servo motor 138 (grinding Z-axis servo motor), a sixteenth servo motor 139 (elevation servo motor), a seventeenth servo motor 140 (cut-in servo motor), a grinding wheel elevation screw 141, and a grinding wheel cut-in screw 142. The grinding jig 137 is formed of a grinding wheel 143, a grinding support 144, a cover plate 145, and a spindle motor 146. The grinding wheel 143 is formed into a disk shape having a predetermined diameter, and grinds the edge (peripheral edge) of the main body 66a of the glass plates 11a and 11b with its outer peripheral surface.

[0128] The grinding bracket 144 is located directly above the grinding wheel 143 and rotatably supports the grinding wheel 143. The cover plate 145 is located directly below the grinding wheel 143 and covers the entire grinding wheel 143. The cover plate 145 is detachably mounted on the grinding fixture 137. The cover plate 145 is formed with a slit 147 at the edge (peripheral portion) of the main body 66a of the glass plates 11a and 11b for inserting. The spindle motor 146 is located directly above the grinding wheel 143 (grinding bracket 144) and is disposed and accommodated in a motor housing 148. The spindle motor 146 has its shaft connected to the center of the grinding wheel 143. The rotation of the shaft of the spindle motor 146 drives the grinding wheel 143 to rotate.

[0129] The motor housing 148 is fixed to the running frame 32 via a bracket 149. The control unit that controls the start and stop, rotation number, and rotation speed of the spindle motor 146 is connected to the controller via an interface (wired or wireless) (not shown). When the control unit of the spindle motor 146 receives a driving signal from the controller, the spindle motor 146 is driven at a specified rotation number and rotation speed, and when a stop signal is received from the controller, the drive of the spindle motor 146 is stopped.

[0130] The fifteenth servo motor 138 (grinding Z-axis servo motor) is located near the rear of the grinding fixture 137, and is connected and fixed to the running frame 32 via a bracket 149. The shaft of the fifteenth servo motor 138 is connected to the support shaft of the motor housing 148. The fifteenth servo motor 138 finely adjusts the axial position (angle around the axis) of the grinding wheel 143 so that the outer peripheral surface of the grinding wheel 143 abuts against the edge (peripheral portion) of the main body 66a of the glass plates 11a and 11b in parallel.

[0131] The sixteenth servo motor 139 (elevation servo motor) is located near the outer side in the width direction of the motor housing 148 (spindle motor 146), and is connected and fixed to the motor housing 148. The shaft of the sixteenth servo motor 139 is connected to the grinding wheel elevation screw 141, and rotates the grinding wheel elevation screw 141. The sixteenth servo motor 139 moves the grinding wheel 143 (motor housing 148) up and down according to the thickness of the glass plates 11a and 11b, and finely adjusts the height of the grinding wheel 143 in such a way that the height of the grinding wheel 143 is consistent with the height of the edge of the main body 66a of the glass plates 11a and 11b and the outer peripheral surface of the grinding wheel 143 abuts against the edge of the main body 66a of the glass plates 11a and 11b.

[0132] In addition, in the initial setting for starting the processing of the glass plates 11a and 11b, the distance from the mounting reference surface of the grinding wheel 143 to the center of the groove is input to the controller. The controller calculates the number of rotations of the shaft of the sixteenth servo motor 139 based on the input distance, and transmits the calculated number of rotations to the control unit of the sixteenth servo motor 139. The control unit of the sixteenth servo motor 139 rotates the shaft of the sixteenth servo motor 139 at the number of rotations received from the controller. When the shaft of the sixteenth servo motor 139 rotates in the clockwise direction at a predetermined number of rotations, the grinding wheel lifting screw 141 rotates in the clockwise direction and the grinding wheel lifting screw 141 descends, so that the grinding wheel 143 (motor housing 148) descends.

[0133] When the shaft of the sixteenth servo motor 139 rotates in the counterclockwise direction at a predetermined number of rotations, the grinding wheel lifting screw 141 rotates in the counterclockwise direction and causes the grinding wheel lifting screw 141 to rise, thereby raising the grinding wheel 143 (motor housing 148). As long as the thickness of the glass plates 11a and 11b to be processed is the same, the height of the grinding wheel 143 only needs to be finely adjusted once, and no subsequent adjustment is required.

[0134] The seventeenth servo motor 140 (cut-in servo motor) is located just below the sixteenth servo motor 139 (elevation servo motor) and near the outer side of the motor housing 148 (spindle motor 146) in the width direction, and is connected and fixed to the motor housing 148. The shaft of the seventeenth servo motor 140 is connected to the grinding wheel cutting screw 142 and rotates the grinding wheel cutting screw 142. The seventeenth servo motor 140 moves the grinding wheel 143 (motor housing 148) in the width direction according to the diameter of the outer peripheral surface of the grinding wheel 143, and finely adjusts the cutting depth of the grinding wheel 143 so that the outer peripheral surface of the grinding wheel 143 abuts against the edge (peripheral portion) of the main body 66a of the glass plates 11a and 11b. The control unit that controls the start and stop of the fifteenth to seventeenth servo motors 138 to 140 and the number of rotations and the rotation speed is connected to the controller through an interface (wired or wireless) (not shown).

[0135] In addition, in the initial setting for starting the processing of the glass plates 11a and 11b, the diameter of the grinding wheel 143 is input to the controller. The controller calculates the number of rotations of the shaft of the seventeenth servo motor 140 based on the input diameter of the grinding wheel 143, and transmits the calculated number of rotations to the control unit of the seventeenth servo motor 140. The control unit of the seventeenth servo motor 140 rotates the shaft of the seventeenth servo motor 140 at the number of rotations received from the controller. When the shaft of the seventeenth servo motor 140 rotates in the clockwise direction at a predetermined number of rotations, the grinding wheel cutting screw 142 rotates in the clockwise direction and the grinding wheel cutting screw 142 moves to the rear in the front-rear direction, so that the grinding wheel 143 (motor housing 148) moves to the rear in the front-rear direction.

[0136] When the shaft of the seventeenth servo motor 140 rotates in the counterclockwise direction at a predetermined number of rotations, the grinding wheel cutting screw 142 rotates in the counterclockwise direction and moves the grinding wheel cutting screw 142 forward in the front-rear direction, thereby moving the grinding wheel 143 (motor housing 148) forward in the front-rear direction. As long as the diameter (diameter) of the grinding wheel 143 is the same, the fine adjustment of the front-rear direction position of the grinding wheel 143 only needs to be set once, and no subsequent adjustment is required.

[0137] The unloading area 23 is provided with an unloading conveyor 150. The unloading area 23 is supported by a foot (pillar) extending upward from the floor surface of the system table 25. The unloading conveyor 150 is a plurality of infinite tracks extending in the front-rear direction (X direction), and is arranged at predetermined intervals in the width direction (Y direction). A control unit that controls the start and stop of these unloading conveyors 150 and the conveying distance is connected to the controller via an interface (wired or wireless) (not shown). These unloading conveyors 150 convey the glass plates 11a and 11b from the rear end (carrying inlet) of the unloading area 23 toward the front end (carrying outlet) and from the rear to the front in the front-rear direction.

[0138] The following describes an embodiment of processing (cutting, breaking, grinding) of the glass plates 11a and 11b. When processing starts, the first glass plate support 40a stands by above the loading area 19, the second glass plate support 40b stands by above the cutting processing area 20, and the third glass plate support 40c stands by above the breaking processing area 21, and the fourth glass plate support 40d stands by above the grinding processing area 22.

[0139] A plurality of glass plate images are output (displayed) on a monitor or display or a touch panel (output device) connected to the controller. From the plurality of glass plate images output (displayed) on the output device, a certain glass plate 11a or 11b to be processed is clicked (tapped) (selected). When the certain glass plate 11a or 11b is selected, the controller selects an NC control program for processing the glass plate 11a or 11b. The controller outputs (displays) on the output device an input area for the distance from the mounting reference surface of the grinding wheel 143 to the center of the groove, an input area for the dimensions of the glass plates 11a or 11b in the front-to-back direction, and an input area for the diameter of the grinding wheel 143.

[0140] After inputting the distance from the mounting reference surface of the grinding wheel 143 to the center of the groove in the input area, and inputting the diameter in the diameter input area of ​​the grinding wheel 143, the input button output (indicated) on the output device is clicked (tapped). When the distance and diameter are input, the controller drives the sixteenth servo motor 139 to move the grinding wheel 143 (motor housing 148) up and down, and fine-adjusts the height of the grinding wheel 143, and drives the seventeenth servo motor 140 to move the grinding wheel 143 (motor housing 148) in the width direction, and fine-adjusts the position of the grinding wheel 143 in the front-back direction. After these fine adjustments are completed, the controller outputs (indicates) the start processing button on the output device. When the start processing button is clicked (tapped), the processing of the glass plates 11a and 11b starts.

[0141] The selected glass plates 11a and 11b of the processing object (before processing) are carried into the carrying-in area 19. In addition, the first positioning unit (first positioning process) and the second positioning unit (second positioning process) are implemented in the carrying-in area 19. The glass plates 11a and 11b of the processing object are automatically supplied to the carrying-in conveyor 53 of the carrying-in area 19 by an automatic supply device (not shown). In the automatic supply device, a plurality of glass plates 11a and 11b of the processing object having the same area (same size) of the upper surface 12 and the lower surface 13 are stacked in the vertical direction, and the glass plates 11a and 11b are supplied to the carrying-in conveyor 53 one by one by the automatic supply device.

[0142] An example of the positioning procedure of the glass plates 11a and 11b in the loading area 19 is as follows. The controller transmits a conveyance signal (ON signal) to the control unit of the loading conveyor 53, and the control unit of the loading conveyor 53 that receives the conveyance signal (ON signal) drives the loading conveyor 53. The glass plates 11a and 11b loaded into the loading area 19 are placed on the loading conveyor 53 in a state where the lower surface 13 thereof abuts against the loading conveyor 53. The first side edge 14 (the side edge 14 on one side) (including the case where the side edge 14 is curved (arc)) of the glass plates 11a and 11b is aligned with the side edge portion 58a on one side of the loading area 19, and the other side edge 15 thereof is aligned with the other side edge portion 58b on the other side of the loading area 19.

[0143] The glass plates 11a and 11b placed on the loading conveyor 53 are gradually moved forward along the front-rear direction from the rear of the loading area 19 to the front by the loading conveyor 53. The glass plates 11a and 11b move forward from the rear of the loading area 19, and when the front edges 16 of the glass plates 11a and 11b abut against the stopper 54, the contact sensor provided on the stopper 54 detects the abutment of the front edges 16 of the glass plates 11a and 11b against the stopper 54, and transmits a contact (abutment) signal to the controller.

[0144] The controller that has received the contact signal transmits a stop signal (OFF signal) to the control unit of the carry-in conveyor 53, and the control unit of the carry-in conveyor 53 that has received the stop signal (OFF signal) stops driving the carry-in conveyor 53. Next, the controller transmits to the control unit of the carry-in conveyor 53 the second moving dimension of the carry-in conveyor 53 in the front-rear direction for positioning the front-rear center O1 (the center line L2 that divides the front-rear dimension of the glass plates 11a and 11b in two and extends in the width direction) of the first side edge 14 of the glass plates 11a and 11b at the rear of the positioning second reference L2 (virtual positioning second reference line) of the carrying-in area 19, and transmits a retreat signal (ON signal) to the control unit of the carry-in conveyor 53.

[0145] The control unit of the carrying-in conveyor 53 that receives the second moving dimension and the retreat signal (ON signal) drives the carrying-in conveyor 53, and moves the glass plates 11a and 11b to the rear in the front-rear direction by the second moving dimension through the carrying-in conveyor 53. When the carrying-in conveyor 53 moves the glass plates 11a and 11b to the rear in the front-rear direction by the second moving dimension, the front-rear center O1 of one side edge of the width direction of the glass plates 11a and 11b (the center line L2 of the glass plates 11a and 11b) is located at the second positioning reference L2 (the virtual positioning second reference line) of the carrying-in area 19 (the second positioning unit (the second positioning step)).

[0146] After the glass sheets 11a and 11b are moved to the rear by the second moving dimension in the front-rear direction, the controller transmits a stop signal (OFF signal) to the control unit of the carrying-in conveyor 53. The control unit of the carrying-in conveyor 53 that receives the stop signal (OFF signal) stops driving the carrying-in conveyor 53. Next, the controller transmits an ascending signal (ON signal) to the control unit of the roller lifting mechanism 56 (cylinder). The control unit of the roller lifting mechanism 56 that receives the ascending signal (ON signal) ascends the roller lifting mechanism 56 (cylinder). The ascending of the roller lifting mechanism 56 causes the rollers 55 to ascend, and a part of the peripheral edge of the rollers 55 is exposed above the carrying-in conveyor 53. In a state where the ascended rollers 55 abut against the lower surfaces 13 of the glass sheets 11a and 11b, the rollers 55 lift the glass sheets 11a and 11b above the carrying-in conveyor 53.

[0147] After the roller lifting mechanism 56 (cylinder) has finished rising, the controller transmits the rotation number of the third servo motor 61 calculated based on the first moving dimension (first moving distance) in the width direction of the moving mechanism 57 for positioning the first side edge 14 of the glass plates 11a and 11b on the first positioning reference L1 (virtual positioning first reference line) to the control unit of the third servo motor 61, and transmits a positive rotation signal (ON signal) to the control unit of the third servo motor 61. The control unit that receives the rotation number of the third servo motor 61 and the positive rotation signal (ON signal) drives the third servo motor 61 and rotates the shaft of the third servo motor 61 in the clockwise direction at a predetermined rotation number.

[0148] The contact member 63 gradually moves from its movement start point to one side in the width direction together with the moving arm 62 by the feed screw rotating due to the clockwise rotation of the shaft of the third servo motor 61. The contact member 63 moving to one side in the width direction contacts the second side edge 15 (the other side edge) of the glass plates 11a and 11b, and the contact member 63 pushes the second side portion 15 of the glass plates 11a and 11b in the width direction in such a manner that the glass plates 11a and 11b move from the other side in the width direction to one side. The glass plates 11a and 11b pushed by the contact member 63 move from the other side in the width direction to one direction in the width direction on the roller 55, and the outermost edge of the first side edge 14 in the width direction of the glass plates 11a and 11b located at the outermost side in the width direction is located at the first positioning reference L1 (virtual positioning first reference line) in the carrying-in area 19 (first positioning unit (first positioning step)).

[0149] When the movement of the contact member 63 to one side in the width direction is completed and the outermost edge of the first side edge 14 in the width direction of the glass plates 11a and 11b located at the outermost side in the width direction is located at the first positioning reference L1 in the carrying-in area 19, the controller transmits a stop signal (OFF signal) to the control unit of the third servo motor 61. The control unit of the third servo motor 61 that receives the stop signal (OFF signal) stops the driving of the third servo motor 61. After the driving of the third servo motor 61 stops, the controller transmits a reverse rotation signal (ON signal) to the control unit of the third servo motor 61. The control unit of the third servo motor 61 that receives the reverse rotation signal (ON signal) drives the third servo motor 61 and rotates the shaft of the third servo motor 61 in the counterclockwise direction only at a predetermined number of rotations.

[0150] The abutting member 63 gradually moves to the other side of the width direction together with the movable arm 62 by the feed screw rotating due to the counterclockwise rotation of the shaft of the third servo motor 61, and the abutting member 63 returns to the starting point of movement. After the abutting member 63 returns to the starting point of movement, the controller transmits a stop signal (OFF signal) to the control unit of the third servo motor 61, and transmits a descending signal (ON signal) to the control unit of the roller lifting mechanism 56 (cylinder). The control unit of the third servo motor 61 that receives the stop signal (OFF signal) stops the driving of the third servo motor 61, and the control unit of the roller lifting mechanism 56 that receives the descending signal (ON signal) causes these roller lifting mechanisms 56 (cylinder) to descend. When these roller lifting mechanisms 56 descend, the lower surfaces 13 of the glass plates 11a and 11b positioned by the first positioning unit (first positioning process) and the second positioning unit (second positioning process) abut against the conveyor 53.

[0151] The breaking system 10a and the grinding method (glass plate processing system 10) are configured such that the glass plates 11a and 11b are moved from the rear to the front of the carrying area 19 by the carrying conveyor 53. After the front edges 16 of the glass plates 11a and 11b abut against the stopper 54, the carrying conveyor 53 moves the glass plates 11a and 11b to the rear in the front-to-back direction. Therefore, the front-to-back center O1 (the center of the glass plates 11a and 11b) of the first side edges 14 in the width direction of the glass plates 11a and 11b is After the center O1 in the front-rear direction of the side edge 14 of one side in the width direction of the glass plates 11a and 11b (the center line L2 of the glass plates 11a and 11b) is positioned at the second positioning reference L2 in the loading area 19 by the second positioning unit (the second positioning step), the glass plates 11a and 11b are raised together with the roller 55 by the roller lifting mechanism 56 (cylinder). Since the second side edge 15 of the raised glass plates 11a and 11b is moved by the moving mechanism 5 7 is pressed and moved in the width direction so that the outermost edge of the first side edges 14 in the width direction of the glass plates 11a and 11b, which is located at the outermost side in the width direction, is positioned at the first positioning reference L1 in the loading area 19. Therefore, at the position of the front-to-back center O1 (the center line L2 of the glass plate 11a) of the first side edge 14 extending in the front-to-back direction on one side in the width direction of the glass plate 11a processed first, the front-to-back center O1 (the center line L2 of the glass plate 11b) of the first side edge 14 extending in the front-to-back direction on one side in the width direction of the glass plate 11b of different areas of the upper and lower surfaces 12 and 13 processed later can be correctly positioned (aligned), and at the position of the outermost edge of the first side edge 14 extending in the front-to-back direction on one side in the width direction of the glass plate 11a processed first, the outermost edge of the first side edge 14 extending in the front-to-back direction on one side in the width direction of the glass plate 11b of different areas of the upper surface 12 and the lower surface 13 processed later can be correctly positioned (aligned).

[0152] Another example of the positioning procedure of the glass plates 11a and 11b in the carrying-in area 19 is as follows. The controller transmits a forward signal (ON signal) to the control unit of the carrying-in conveyor 53, and the control unit of the carrying-in conveyor 53 that receives the forward signal (ON signal) drives these carrying-in conveyors 53. The glass plates 11a and 11b carried into the carrying-in area 19 are placed on the carrying-in conveyor 53 in a state where the lower surface 13 thereof abuts against the carrying-in conveyor 53. The glass plates 11a and 11b placed on the carrying-in conveyor 53 are gradually moved from the rear (starting position) of the carrying-in area 19 to the front in the front-rear direction by the carrying-in conveyor 53. The glass plates 11a and 11b move from the rear to the front of the loading area 19. When the front end edges 16 of the glass plates 11a and 11b abut the stopper 54, the contact sensor provided on the stopper 54 detects the abutment of the front end edges 16 of the glass plates 11a and 11b against the stopper 54 and transmits a contact signal to the controller.

[0153] The controller that receives the contact signal transmits a stop signal (OFF signal) to the control unit of the transport conveyor 53, and the control unit of the transport conveyor 53 that receives the stop signal (OFF signal) stops driving the transport conveyors 53. Next, the controller transmits an ascending signal (ON signal) to the control unit of the roller lifting mechanism 56 (cylinder). The control unit of the roller lifting mechanism 56 that receives the ascending signal (ON signal) causes the roller lifting mechanism 56 (cylinder) to ascend. The rollers 55 are ascended by the ascending of the roller lifting mechanism 56, and a part of the peripheral edge of the rollers 55 is exposed above the transport conveyors 53. In a state where the ascended rollers 55 abut against the lower surface 13 of the glass plates 11a and 11b, the rollers 55 lift the glass plates 11a and 11b above the transport conveyors 53.

[0154] After the roller lifting mechanism 56 (cylinder) has finished rising, the controller transmits the rotation number of the third servo motor 61 calculated based on the first moving dimension (first moving distance) in the width direction of the moving mechanism 57 for positioning the first side edge 14 of the glass plates 11a and 11b at the first positioning reference L1 (virtual positioning first reference line) to the control unit of the third servo motor 61, and at the same time, transmits a positive rotation signal (ON signal) to the control unit of the third servo motor 61. The control unit of the third servo motor 61, which receives the rotation number and the positive rotation signal (ON signal), drives the third servo motor 61 so that the shaft of the third servo motor 61 rotates in the clockwise direction only at a specified rotation number.

[0155] The contact member 63 gradually moves from its movement start point to one side in the width direction (side portion 58a of the carrying-in area 19) together with the moving arm 62 by the feed screw rotating due to the clockwise rotation of the shaft of the third servo motor 61. The contact member 63 moving to one side in the width direction contacts the second side edge 15 of the glass plates 11a and 11b, and the contact member 63 pushes the second side edge 15 of the glass plates 11a and 11b in the width direction so that the glass plates 11a and 11b move from the other side in the width direction to one side. The glass plates 11a and 11b pushed by the contact member 63 move from the other side in the width direction to one direction in the width direction on the roller 55, and the outermost edge of the first side edge 14 in the width direction of the glass plates 11a and 11b located at the outermost side in the width direction is located at the first positioning reference L1 (virtual positioning first reference line) in the carrying-in area 19 (first positioning unit (first positioning step)).

[0156] When the movement of the contact member 63 to one side in the width direction is completed and the first side edge 14 in the width direction of the glass plates 11a and 11b is located at the first positioning reference L1 in the carrying-in area 19, the controller transmits a stop signal (OFF signal) to the control unit of the third servo motor 61. The control unit of the third servo motor 61, which receives the stop signal (OFF signal), stops the driving of the third servo motor 61. After the driving of the third servo motor 61 stops, the controller transmits a reverse rotation signal (ON signal) to the control unit of the third servo motor 61. The control unit of the third servo motor 61, which receives the reverse rotation signal (ON signal), drives the third servo motor 61 and rotates the shaft of the third servo motor 61 in the counterclockwise direction only at a predetermined number of rotations.

[0157] The feed screw rotates due to the counterclockwise rotation of the shaft of the third servo motor 61, and the contact member 63 gradually moves to the other side in the width direction (the side 58b of the carrying-in area 19) together with the movable arm 62, and the contact member 63 returns to the moving starting point. After the contact member 63 returns to the moving starting point, the controller transmits a stop signal (OFF signal) to the control unit of the third servo motor 61, and transmits a descending signal (ON signal) to the control unit of the roller lifting mechanism 56 (cylinder). The control unit of the third servo motor 61 that receives the stop signal (OFF signal) stops the driving of the third servo motor 61, and the control unit of the roller lifting mechanism 56 that receives the descending signal (ON signal) causes these roller lifting mechanisms 56 (cylinder) to descend. When these roller lifting mechanisms 56 descend, the lower surfaces 13 of the glass plates 11a and 11b abut against the carrying-in conveyor 53.

[0158] After the lower surface 13 of the glass plates 11a and 11b abuts against the loading conveyor 53, the controller transmits the second moving dimension of the loading conveyor 53 in the forward and backward direction to the rear of the second positioning reference L2 (virtual positioning second reference line) of the loading area 19, which is used to position the front-to-back center O1 of the first side edge 14 of the glass plates 11a and 11b, to the control unit of the loading conveyor 53, and at the same time, transmits the conveying signal (ON signal) to the control unit of the loading conveyor 53.

[0159] The control unit of the carrying-in conveyor 53 receiving the second moving dimension and the conveying signal (ON signal) drives the carrying-in conveyor 53, and moves the glass plates 11a and 11b to the rear in the front-rear direction by the second moving dimension through the carrying-in conveyor 53. When the carrying-in conveyor 53 moves the glass plates 11a and 11b to the rear in the front-rear direction by the second moving dimension, the front-rear center O1 of the first side edge 14 in the width direction of the glass plates 11a and 11b (the center line L2 that divides the front-rear dimension of the glass plates 11a and 11b in two and extends in the width direction) is located at the positioning second reference L2 (virtual positioning second reference line) in the carrying-in area 19 (second positioning unit (second positioning step)). After moving the glass plates 11a and 11b to the rear in the front-rear direction by the second moving dimension, the controller transmits a stop signal (OFF signal) to the control unit of the carrying-in conveyor 53, and the control unit of the carrying-in conveyor 53 receiving the stop signal (OFF signal) stops driving the carrying-in conveyor 53. The glass plates 11 a and 11 b are positioned by the first positioning unit (first positioning step) and the second positioning unit (second positioning step).

[0160] The breaking system 10a and the grinding method (glass plate processing system 10) are configured to move the glass plates 11a and 11b from the rear to the front of the carrying area 19 by the carrying conveyor 53. After the front edges 16 of the glass plates 11a and 11b abut against the stopper 54, the glass plates 11a and 11b are raised together with the rollers 55 by the roller lifting mechanism 56 (cylinder), and the second side edges 15 of the raised glass plates 11a and 11b are pushed and moved in the width direction by the moving mechanism 57, and the first side edges 14 in the width direction of the glass plates 11a and 11b are positioned at the middle of the first side edges 14 in the width direction of the glass plates 11a and 11b. The outermost edge of the first side edge 14 in the width direction of the glass plates 11a and 11b is positioned at the first positioning reference L1 in the carrying-in area 19. After the outermost edge of the first side edge 14 in the width direction of the glass plates 11a and 11b located at the outermost edge in the width direction is positioned at the first positioning reference L1 by the first positioning unit (first positioning step), the glass plates 11a and 11b are lowered together with the roller 55 by the roller lifting mechanism 56 (cylinder), and the glass plates 11a and 11b are moved from the rear to the front in the carrying-in area 19 by the carrying-in conveyor 53, and the front end edges 16 of the glass plates 11a and 11b abut against the limit After the positioning device 54 is installed, the glass plates 11a and 11b are moved to the rear in the front-rear direction by the carrying-in conveyor 53, and the front-rear center O1 of the first side edge 14 in the width direction of the glass plates 11a and 11b (the center line L2 of the glass plates 11a and 11b) is positioned at the second positioning reference L2 of the carrying-in area 19. Therefore, at the position of the outermost edge of the first side edge 14 extending in the front-rear direction on one side in the width direction of the glass plate 11a to be processed first, the glass plates 11b having different areas of the upper surface 12 and the lower surface 13 to be processed later are positioned at the outermost edge of the first side edge 14 extending in the front-rear direction on one side in the width direction of the glass plate 11a to be processed first. The outermost edge of the first side edge 14 extending in the front-to-rear direction on one side in the width direction can be correctly positioned (aligned), and at the position of the front-to-rear center O1 (center line L2 of the glass plate 11a) of the first side edge 14 extending in the front-to-rear direction on one side in the width direction of the glass plate 11a processed first, the front-to-rear center O1 (center line L2 of the glass plate 11b) of the side edge 14 extending in the front-to-rear direction on one side in the width direction of the glass plate 11b having upper and lower surfaces 12 and 13 of different sizes that are processed subsequently can be correctly aligned (positioned).

[0161] In the breaking system 10a and the breaking method (glass plate processing system 10), when a large-sized glass plate 11a having a larger area of ​​upper and lower surfaces 12 and 13 and a small-sized glass plate 11b having a smaller area of ​​upper and lower surfaces 12 and 13 than the large-sized glass plate 11a are positioned by a first positioning unit (first positioning step) and a second positioning unit (second positioning step), as shown in FIG. Figure 3As shown, the first side edge 14 (side edge on one side) of the large-sized glass plate 11a extending in the front-rear direction and the first side edge 14 (side edge on one side) of the small-sized glass plate 11b extending in the front-rear direction are located at the first positioning reference L1 (virtual positioning first reference line) of the carrying-in area 19, and the front-rear center O1 of the first side edge 14 extending in the front-rear direction of the large-sized glass plate 11a and the front-rear center O1 of the first side edge 14 extending in the front-rear direction of the small-sized glass plate 11b are located at the second positioning reference L2 (virtual positioning second reference line) of the carrying-in area 19.

[0162] For the large-sized glass plate 11a and the small-sized glass plate 11b positioned by the first positioning unit (first positioning process) and the second positioning unit (second positioning process), the outermost edges of the first side edges 14 of these glass plates 11a and 11b located on the outermost sides in the width direction (the first side edges 14 in the illustrated glass plates 11a and 11b) are aligned with the first positioning datum L1 (virtual positioning first datum line), and the front-to-back centers O1 (the center line L2 that divides the front-to-back dimensions of the glass plates 11a and 11b into two and extends in the width direction) of the first side edges 14 of these glass plates 11a and 11b are aligned with the second positioning datum L2 (virtual positioning second datum line).

[0163] After the glass plates 11a and 11b are positioned by the first positioning unit (first positioning process) and the second positioning unit (second positioning process), the controller transmits a descending signal (ON signal) to the control unit of the lifting mechanism (servo motor) of the first glass plate holder 40a. The control unit of the lifting mechanism (servo motor) that receives the descending signal (ON signal) lowers the holder suction cup 42 (adsorption pad) toward the upper surface 12 of the glass plates 11a and 11b through the lifting mechanism. After the holder suction cup 42 of the first glass plate holder 40a abuts against the upper surface 12 of the glass plates 11a and 11b, the controller transmits a suction signal (ON signal) to the control unit of the vacuum mechanism of the first glass plate holder 40a. The control unit of the vacuum mechanism that receives the suction signal (ON signal) starts the vacuum mechanism.

[0164] By starting the vacuum mechanism, the glass plates 11a and 11b located in the carrying-in area 19 are sucked by the holder suction cup 42. After starting the vacuum mechanism, the controller transmits an ascending signal (ON signal) to the control unit of the pad lifting mechanism (cylinder) of the first glass plate holder 40a. The control unit of the pad lifting mechanism (cylinder) that receives the ascending signal (ON signal) raises the holder suction cup 42 through the pad lifting mechanism. In the carrying-in area 19, the glass plates 11a and 11b positioned by the first positioning unit (first positioning process) and the second positioning unit (second positioning process) are raised together with the holder suction cup 42 in a state of being adsorbed and held on the holder suction cup 42.

[0165] After the holder suction cup 42 (glass plates 11a, 11b) rises, the controller transmits a forward signal (ON signal) to the control unit of the second servo motor 39. The control unit of the second servo motor 39 that receives the forward signal (ON signal) drives the second servo motor 39. Due to the rotation of the shaft of the second servo motor 39, the slider moves from the rear to the front of the second guide frame 35 in the front-to-back direction, so that the first glass plate holder 40a (glass plates 11a, 11b held by the holder suction cup 42 (adsorption pad)) moves from the carrying-in area 19 to the cutting processing area 20 (glass plate moving unit (glass plate moving process)). In addition, due to the movement of the slider, the second to fourth glass plate holders 40b to 40d move forward in the front-to-back direction together with the first glass plate holder 40a.

[0166] After the first glass plate holder 40a moves to the cutting process area 20, the controller transmits a descending signal (ON signal) to the control unit of the pad lifting mechanism (cylinder) of the first glass plate holder 40a. The control unit of the pad lifting mechanism (cylinder) receiving the descending signal (ON signal) lowers the holder suction cup 42 (glass plates 11a, 11b) to the cutting process table 64 of the cutting process area 20 through the pad lifting mechanism. After the glass plates 11a, 11b adsorbed by the holder suction cup 42 of the first glass plate holder 40a abut against the cutting process table 64, the controller transmits a stop signal (OFF signal) to the control unit of the vacuum mechanism of the first glass plate holder 40a. The control unit of the vacuum mechanism receiving the stop signal (OFF signal) stops the start of the vacuum mechanism. Since the vacuum mechanism is stopped, the holder suction cup 42 is released from adsorbing the glass plates 11a, 11b, and the positioned glass plates 11a, 11b are placed on the cutting process table 64.

[0167] Next, the controller transmits an ascending signal (ON signal) to the control unit of the pad lifting mechanism (cylinder) of the first glass plate holder 40a, and the ascending signal causes the first glass plate holder 40a (pad lifting mechanism) to ascend above the cutting processing table 64. After the first glass plate holder 40a ascends, the controller transmits a retreating signal (ON signal) to the control unit of the second servo motor 39, and the rotation of the shaft of the second servo motor 39 causes the first glass plate holder 40a to move from the cutting processing area 20 to the carrying-in area 19, and the first glass plate holder 40a waits above the carrying-in area 19. In addition, together with the first glass plate holder 40a, the second to fourth glass plate holders 40b to 40d also move to the rear in the front-back direction, and the second glass plate holder 40b waits above the cutting processing area 20, the third glass plate holder 40c waits above the breaking processing area 21, and the fourth glass plate holder 40d waits above the grinding processing area 22.

[0168] The procedure for transporting the glass plates 11a and 11b after the cutting process from the cutting process area 20 to the breaking process area 21 (glass plate moving unit (glass plate moving process)) performed by the second glass plate bracket 40b, the procedure for transporting the glass plates 11a and 11b after the breaking process from the breaking process area 21 to the grinding process area 22 (glass plate moving unit (glass plate moving process)) performed by the third glass plate bracket 40c, and the procedure for transporting the glass plates 11a and 11b after the grinding process from the grinding process area 22 to the unloading area 23 (glass plate moving unit (glass plate moving process)) performed by the fourth glass plate bracket 40d are the same as the procedure for transporting the glass plates 11a and 11b from the loading area 19 to the cutting process area 20 performed by the first glass plate bracket 40a, so the description of the transporting procedures performed by the second to fourth glass plate brackets 40b to 40d is omitted.

[0169] After the glass plates 11a and 11b are placed on the cutting processing table 64, the controller transmits a retracting signal (ON signal) to the control unit of the first servo motor 34. The control unit of the first servo motor 34, which receives the retracting signal (ON signal), drives the first servo motor 34. The rotation of the shaft of the first servo motor 34 causes the first slider to move from the front to the rear of the first guide frame 30 in the front-to-rear direction, so that the cutting device 65 moves in the front-to-rear direction in the cutting processing area 20 together with the first operating frame 32, and the cutting device 65 is located outside the first corner 18a (front end edge 16) of the glass plates 11a and 11b in the width direction (cutting processing start position).

[0170] In addition, during the cutting process, although not shown in the figure, the second glass plate holder 40b that moves from the breaking process area 21 to (returns to) the cutting process area 20 is lowered to the cutting process table 64 of the cutting process area 20 by the pad lifting mechanism (cylinder), and the holder suction cup 42 (adsorption pad) of the second glass plate holder 40b abuts against the upper surface 12 of the glass plates 11a and 11b placed on the cutting process table 64, and the vacuum mechanism is started. While the holder suction cup 42 adsorbs the glass plates 11a and 11b, the adsorption pad 42 of the second glass plate holder 40b pushes the glass plates 11a and 11b downward. During the cutting process, the glass plates 11a and 11b are supported by the holder suction cup 42 of the second glass plate holder 40b in a pushed state.

[0171] After the cutting device 65 is located outside the first corner 18a of the glass plates 11a and 11b in the width direction (cutting process start position), the controller transmits a stop signal (OFF signal) to the control unit of the first servo motor 34 and a drive signal (ON signal) to the control unit of the fourth servo motor 71. The control unit of the first servo motor 34 that receives the stop signal (OFF signal) stops the first servo motor 34, and the control unit of the fourth servo motor 71 that receives the drive signal (ON signal) drives the fourth servo motor 71. The slider 73a moves the feed screw 70a from the other side edge 58b of the cutting process area 20 toward the one side edge 58a in the width direction by the rotation of the shaft of the fourth servo motor 71, so that the cutting process table 64 moves from the other side edge 58b of the cutting process area 20 toward the one side edge 58a in the width direction, and the cutting cutter wheel 77 of the cutting device 65 is located at the first corner 18a of the glass plates 11a and 11b.

[0172] After the cutting wheel 77 of the cutting device 65 is located at the first corner 18a of the glass plates 11a, 11b, the controller transmits the drive signal (ON signal) and the NC control signal to the cylinder 75 of the cutting device 65 and the control unit of the fifth servo motor 76, and transmits the retract signal (ON signal) and the NC control signal to the control unit of the first servo motor 34, while transmitting the NC control signal to the control unit of the fourth servo motor 71. The control unit of the cylinder 75, the control unit of the fifth servo motor 76, the control unit of the first servo motor 34, and the control unit of the fourth servo motor 71 of the cutting device 65 which receive the driving signal (ON signal) and the NC control signal, drive the cylinder 75, the fifth servo motor 76, the first servo motor 34, and the fourth servo motor 71, and perform contour control movement based on NC control on the first side edge 14 (first side edge portion) of the glass plates 11a and 11b, and the cutting wheel 77 performs cutting processing on the first side edge 14 (first side edge portion) of the glass plates 11a and 11b (cutting processing unit (cutting processing step)).

[0173] During the cutting process, the control unit of the first servo motor 34 receiving the retreat signal (ON signal) drives the first servo motor 34 to move the cutting device 65 to the rear in the front-rear direction in the cutting process area 20, and the control unit of the fourth servo motor 71 drives the fourth servo motor 71 to move the cutting device 65 back and forth in the width direction in the cutting process area 20. The cutting cutter wheel 77 of the cutting device 65 forms the outer shape cutting line K1 near the first side edge 14 (first side edge portion) of the glass plates 11a and 11b, and moves from the first corner 18a of the glass plates 11a and 11b toward the second corner 18b.

[0174] With the help of the cutting wheel 77 of the cutting device 65, the cutting process near the first side edge 14 (first side edge portion) of the glass plates 11a and 11b is completed. After the cutting wheel 77 is located at the second corner 18b of the glass plates 11a and 11b, the cutting processing workbench 64 moves in the width direction from one side of the side edge portion 58a of the cutting processing area 20 toward the other side of the side edge portion 58b. As the cutting processing workbench 64 moves in the width direction, the cutting wheel 77 performs cutting processing on the rear end edge 17 (rear end edge portion) of the glass plates 11a and 11b (cutting processing unit (cutting processing step)).

[0175] During the cutting process, the control unit of the fourth servo motor 71 drives the fourth servo motor 71 to move the cutting process table 64 in the width direction in the cutting process area 20, and the control unit of the first servo motor 34 drives the first servo motor 34 to move the cutting device 65 back and forth in the front and rear directions in the cutting process area 20. The cutting cutter wheel 77 of the cutting device 65 forms the outer shape cutting line K1 near the rear end edge 17 (rear end edge) of the glass plates 11a and 11b, and moves from the second corner 18b to the third corner 18c of the glass plates 11a and 11b.

[0176] With the help of the cutting wheel 77 of the cutting device 65, the cutting process near the rear end edge 17 (rear end edge portion) of the glass plates 11a and 11b is completed. After the cutting wheel 77 is located at the third corner portion 18c of the glass plates 11a and 11b, the cutting device 65 moves forward in the front-to-rear direction. As the cutting device 65 moves forward in the front-to-rear direction, the cutting wheel 77 performs cutting processing on the second side edge 15 (second side edge portion) of the glass plates 11a and 11b (cutting processing unit (cutting processing step)).

[0177] During the cutting process, the control unit of the first servo motor 34 drives the first servo motor 34 to move the cutting device 65 forward in the front-rear direction in the cutting process area 20, and the control unit of the fourth servo motor 71 drives the fourth servo motor 71 to move the cutting process table 64 back and forth in the width direction in the cutting process area 20. The cutting cutter wheel 77 of the cutting device 65 forms the outer shape cutting line K1 near the second side edge 15 (second side edge portion) of the glass plates 11a and 11b, and moves from the third corner portion 18c to the fourth corner portion 18d of the glass plates 11a and 11b.

[0178] After the cutting process is completed on the second side edge (second side edge portion) of the glass plates 11a and 11b by means of the cutting wheel 77 of the cutting device 65, and the cutting wheel 77 is located at the fourth corner 18d of the glass plates 11a and 11b, the cutting processing workbench 64 moves in the width direction from the side edge 58b of the other side of the cutting processing area 20 toward the side edge 58a of one side. As the cutting processing workbench 64 moves in the width direction, the cutting wheel 77 performs cutting processing on the front end edge 16 (front end edge portion) of the glass plates 11a and 11b (cutting processing unit (cutting processing step)).

[0179] During the cutting process, the control unit of the fourth servo motor 71 drives the fourth servo motor 71 to move the cutting process table 64 in the width direction in the cutting process area 20, and the control unit of the first servo motor 34 drives the first servo motor 34 to move the cutting device 65 back and forth in the front and rear directions in the cutting process area 20. The cutting cutter wheel 77 of the cutting device 65 forms the outer shape cutting line K1 near the front edge 16 (front edge portion) of the glass plates 11a and 11b, and moves from the fourth corner 18d of the glass plates 11a and 11b toward the first corner 18a. When the cutting process of the front edge 16 (front edge portion) of the glass plates 11a and 11b by the cutting cutter wheel 77 of the cutting device 65 is completed, the cutting device 65 moves to the outer side of the first corner 18a (front edge 16) of the glass plates 11a and 11b in the width direction (cutting process start position) and waits.

[0180] In the processing area 20, for example, by the first positioning unit (first positioning process), the outermost edge (the first side edge 14 in the illustrated glass plate 11a) in the width direction of the first side edge 14 extending in the forward and backward directions of the glass plate 11a with a large size (large area) having a large upper surface 12 and a lower surface 13 to be processed first is located at the position (positioning first reference L1 (virtual positioning first reference line)) of the outermost edge in the width direction, so that the glass plate 11b with a small size (small area) having a small upper surface 12 and a lower surface 13 to be processed later is positioned at the outermost edge in the width direction. The outermost edge of the first side edge 14 extending in the front-to-back direction on the first side edge 14 on the first side edge 14 on the second side edge 14 on the second side edge 14 on the second side edge 14 on the outermost side in the width direction (the first side edge 14 in the illustrated glass plate 11b) is positioned (aligned) to position the glass plates 11a and 11b having different areas of the upper surface 12 and the lower surface 13. At the same time, the second positioning unit (second positioning process) is used to align the front-to-back center O1 (the center line L2 that divides the front-to-back dimension of the glass plate 11a in two and extends in the width direction) of the first side edge 14 extending in the front-to-back direction on one side of the width direction of the previously processed large-sized glass plate 11a. The cutting device 65 is configured to be aligned with the position (positioning second reference L2 (virtual positioning second reference line)) of the front-rear direction center O1 (a center line L2 that divides the front-rear direction dimension of the glass plate 11b into two and extends in the width direction) of the first side edge 14 extending in the front-rear direction on one side of the width direction of the glass plate 11b of the small size to be processed later, and after positioning the glass plates 11a and 11b of different areas on the upper surface 12 and the lower surface 13, when the glass plates 11b of different areas to be processed later are cut, the cutting device 65 is configured to be aligned with the side edge 14 of the glass plate 11a of the large size. The moving distance (moving distance of the cutting processing workbench 64 in the width direction) is equal to the moving distance (moving distance of the cutting processing workbench 64 in the width direction) until the cutting device 65 reaches the side edge 14 of the small-sized glass plate 11b. At the same time, the moving distance of the cutting device 65 from the outermost edge (first side edge 14) of the large-sized glass plate 11a to return to the outer side of the glass plate 11a in the width direction is equal to the moving distance of the cutting device 65 from the outermost edge (first side edge 14) of the small-sized glass plate 11b to return to the outer side of the glass plate 11b in the width direction. While the moving distance of the cutting device 65 to reach the outermost edge (side edge 14) of the small-sized glass plate 11b becomes shorter, the moving distance of the cutting device 65 from the outermost edge (side edge 14) of the small-sized glass plate 11b to returning to the outer side in the width direction of the glass plate becomes shorter. While the arrival time (non-processing time) of the cutting device 65 to reach the outermost edge (side edge 14) of the small-sized glass plate 11b is shortened, the return time of the cutting device 65 from the outermost edge (side edge 14) of the small-sized glass plate 11b to returning to the outer side in the width direction of the glass plate is shortened.

[0181] In the breaking system 10a and the breaking processing method (glass plate processing system 10), a first positioning unit (first positioning step) is used to position the outermost edge (the first side edge 14 in the illustrated glass plate 11a) located at the outermost side in the width direction of the first side edge 14 extending in the forward and backward direction on one side of the width direction of the large-sized (large-area) glass plate 11a having a larger area of ​​the upper surface 12 and the lower surface 13 to be processed first (positioning first reference L1 (virtual positioning first reference line)) and the outermost edge (the first side edge 14 in the illustrated glass plate 11a) located at the outermost side in the width direction of the first side edge 14 extending in the forward and backward direction on one side of the width direction of the small-sized (small-area) glass plate 11b having a smaller area of ​​the upper surface 12 and the lower surface 13 to be processed later. The position (positioning first reference L1 (virtual positioning first reference line)) of the first side edge 14 (in the illustrated glass plate 11b, it is the first side edge 14) is aligned, and the glass plates 11a and 11b having different area sizes of the upper surface 12 and the lower surface 13 are positioned. At the same time, through the second positioning unit (second positioning step), the position (positioning second reference L2 (virtual positioning second reference line)) of the front-to-back center O1 (a center line L2 that divides the front-to-back dimension of the glass plate 11a in two and extends in the width direction) of the first side edge 14 extending in the front-to-back direction on one side in the width direction of the large-sized glass plate 11a processed previously is aligned with the front-to-back center O1 (a center line L2 that divides the front-to-back dimension of the glass plate 11a in two and extends in the width direction) of the small-sized glass plate 11b processed subsequently. The position (positioning second reference L2 (virtual positioning second reference line)) of the front-to-back center O1 of the first side edge 14 extending in the front-to-back direction (center line L2 that divides the dimension of the glass plate 11b in the front-to-back direction into two and extends in the width direction) of the glass plate 11a is aligned, and after positioning the glass plates 11a and 11b of different sizes of the upper surface 12 and the lower surface 13, due to the subsequent cutting process of the small-sized glass plate 11b (glass plates 11b of different areas), the moving distance (moving distance of the cutting process workbench 64 in the width direction) until the cutting device 65 reaches the outermost edge (side edge 14) of the large-sized (large-area) glass plate 11a with a larger area of ​​the upper surface 12 and the lower surface 13 is consistent with The moving distance (moving distance of the cutting processing worktable 64 in the width direction) of the cutting device 65 until it reaches the outermost edge (side edge 14) of the small-sized (small-area) glass plate 11b whose upper surface 12 and lower surface 13 are smaller is equal, and at the same time, the moving distance (moving distance of the cutting processing worktable 64 in the width direction) of the cutting device 65 from the outermost edge (side edge 14) of the large-sized glass plate 11a to return to the outer side in the width direction of the glass plate 11a is equal to the moving distance (moving distance of the cutting processing worktable 64 in the width direction) of the cutting device 65 from the outermost edge (side edge 14) of the small-sized glass plate 11b to return to the outer side in the width direction of the glass plate 11b.The moving distance of the cutting device 65 until it reaches the outermost edge (side edge 14) of the small-sized glass plate 11b can be shortened, and the moving distance of the cutting device 65 until it returns from the outermost edge (side edge 14) of the small-sized glass plate 11b to the outer side in the width direction of the glass plate can be shortened. The arrival time (non-processing time) of the cutting device 65 until it reaches the outermost edge (side edge 14) of the small-sized glass plate 11b can be shortened, and the return time of the cutting device 65 until it returns from the outermost edge (side edge 14) of the small-sized glass plate 11b to the outer side in the width direction of the glass plate can be shortened.

[0182] Fig.30 1 is a diagram showing an example of a change in the rotation direction of the break cutter wheel 103. Fig.31 This is a diagram showing another example of changing the rotation direction of the breaking cutter wheel 103. Fig.32 FIG. 2 is a diagram showing another example of changing the rotation direction of the breaking cutter wheel 103. Fig.33 This is a diagram showing an example of a breaking procedure in a breaking process.

[0183] After the cutting process (outline cut line K1) is completed for the edge 66b (peripheral portion) of the glass plates 11a and 11b, the glass plates 11a and 11b after the cutting process are transported from the cutting process area 20 to the breaking process area 21 by the second glass plate support 40b. In the breaking process area 21, the edge 66b extending to the outside of the outline cut line K1 of the glass plates 11a and 11b after the cutting process is cut by the end cut line K2, and the edge 66b of the glass plates 11a and 11b surrounded by the outline cut line K1 and the end cut line K2 is broken.

[0184] In addition, during the breaking process, although not shown in the figure, the third glass plate holder 40c moved from the grinding process area 22 to (returned to) the breaking process area 21 is lowered to the breaking process table 84 of the breaking process area 21 by the pad lifting mechanism (cylinder), and the holder suction cup 42 (adsorption pad) of the third glass plate holder 40c abuts against the upper surface 12 of the glass plates 11a and 11b placed on the breaking process table 84, and the vacuum mechanism is started. While the holder suction cup 42 adsorbs the glass plates 11a and 11b, the holder suction cup 42 of the third glass plate holder 40c pushes the glass plates 11a and 11b downward. During the breaking process, the glass plates 11a and 11b are supported by the holder suction cup 42 of the third glass plate holder 40c under pressure.

[0185] After the cut-in glass plates 11a and 11b are placed on the breaking table 84, the controller transmits a drive signal (ON signal) to the control units of the support lifting mechanism 104, the first pushing member lifting mechanism 106a, the second pushing member lifting mechanism 106b, the sixth servo motor 95 (X-axis servo motor), the seventh servo motor 97 (Y-axis servo motor), the eighth servo motor 100 (X-axis servo motor), and the ninth servo motor 101 (Y-axis servo motor) of the first breaking device 85a and the second breaking device 85b. The control unit of the support lifting mechanism 104, the control units of the first and second pushing member lifting mechanisms 106a and 106b, and the control units of the sixth to ninth servo motors 95, 97, 100, and 101 that receive the drive signal (ON signal) drive the support lifting mechanism 104, the first and second pushing member lifting mechanisms 106a and 106b, and the sixth to ninth servo motors 95, 97, 100, and 101. In addition, the controller transmits instructions (signals) to the bracket lifting mechanism 104 and the first and second pushing part lifting mechanisms 106a, 106b, and the sixth to ninth servo motors 95, 97, 100, 101 in such a manner that the first and second breaking devices 85a, 85b run (move) along a predetermined running trajectory (breaking trajectory) on the upper surface of the glass plates 11a, 11b.

[0186] The first breaking device 85a driven by the bracket lifting mechanism 104, the first and second pushing part lifting mechanisms 106a, 106b, and the sixth to ninth servo motors 95, 97, 100, 101, has a first breaking clamp 94a (breaking clamp) that moves in the front and rear directions and the width direction (oblique direction) through the X-axis first actuator 96a and the Y-axis first actuator 98a. The first breaking clamp 94a is located at the breaking starting position in the first (primary) end tangent forming area on the outside of the first corner 18a in the width direction of the glass plates 11a, 11b.

[0187] The second breaking device 85b is driven by the bracket lifting mechanism 104, the first and second pushing part lifting mechanisms 106a, 106b, and the sixth to ninth servo motors 95, 97, 100, 101. Its second breaking clamp 94b (breaking clamp) is moved in the front and rear directions and the width direction (oblique direction) by the X-axis second actuator 96b and the Y-axis second actuator 98b. The second breaking clamp 94b is located at the first (primary) end tangent forming area outside the fourth corner 18d in the width direction of the glass plates 11a, 11b at the breaking starting position.

[0188] After the first breaking jig 94a of the first breaking device 85a is positioned at the breaking start position (outer side in the width direction) of the first corner portion 18a of the glass plates 11a and 11b, Fig.30As shown by the arrows, the X-axis first actuator 96a and the Y-axis first actuator 98a move in the front-rear direction and the width direction (diagonal direction) to the rotation direction change position near (close to) the outer shape cutting line K1 in the edge 66b of the glass plates 11a and 11b extending outside the outer shape cutting line K1. After the first breaking jig 94a moves to the rotation direction change position near the outer shape cutting line K1, the support lifting mechanism 104 (first lifting mechanism) operates and the breaking cutter support 102 is lowered toward the upper surface 12 of the edge 66b of the glass plates 11a and 11b (support device lowering unit (support device lowering process)).

[0189] After the second breaking jig 94b of the second breaking device 85b is located at the breaking start position (outer side in the width direction) of the fourth corner portion 18d of the glass plates 11a and 11b, Fig.30 As shown by the arrows, the second X-axis actuator 96b and the second Y-axis actuator 98b move in the front-rear direction and the width direction (diagonal direction) to the rotation direction change area near (close to) the outer shape cutting line K1 in the edge 66b of the glass plates 11a and 11b extending to the outside of the outer shape cutting line K1. After the second breaking fixture 94b moves to the rotation direction change area near the outer shape cutting line K1, the support lifting mechanism 104 operates and the breaking cutter support 102 descends toward the upper surface 12 of the edge 66b of the glass plates 11a and 11b (support device descending unit (support device descending process)). In addition, the rotation direction change area may not be near the outer shape cutting line K1, but may be near the periphery of the glass plates 11a and 11b.

[0190] When the breaking cutter support 102 descends, the breaking cutter wheel 103 is exposed downward from the through hole 116 formed in the center of the second pressing member 105b. When the breaking cutter wheel 103 is exposed below the through portion 116, the breaking cutter wheel 103 abuts against the upper surface 12 of the glass plates 11a and 11b in the rotation direction change area with a predetermined pressing force. At this time, the rotation direction of the breaking cutter wheel 103 has not yet been determined, and the peripheral edge 112 of the breaking cutter wheel 103 faces any one of the four directions. The rotation direction of the breaking cutter wheel 103 is not consistent with the extension direction of the virtual end tangent of the edge 66b of the glass plates 11a and 11b.

[0191] The controller transmits an operation signal to the control unit of the sixth and seventh servomotors 95 and 97 in order to make the breaking cutter wheel 103 run (move) in a specified direction. The control unit of the sixth and seventh servomotors 95 and 97, which receives the operation signal, drives the sixth and seventh servomotors 95 and 97. By driving the sixth and seventh servomotors 95 and 97, the first actuator 96a of the X axis and the first actuator 98a of the Y axis operate, and the breaking cutter wheel 103 slightly runs (moves) in a specified direction, so that the breaking cutter wheel 103 exerts a caster effect, and the breaking cutter wheel 103 rotates in the direction around (around the axis) the center axis O2 of the cutter holder (clockwise or counterclockwise), and the rotation (movement) direction of the peripheral edge 112 of the breaking cutter wheel 103 is the running (movement) direction (extension direction of the virtual end tangent) toward the first breaking jig 94a (breaking cutter holder 102) (rotation direction changing unit (rotation direction changing process)).

[0192] The controller transmits an operation signal to the control units of the eighth and ninth servo motors 100 and 101 in order to make the breaking cutter wheel 103 run (move) in a specified direction. The control units of the eighth and ninth servo motors 100 and 101 that receive the operation signal drive the eighth and ninth servo motors 100 and 101. The driving of the eighth and ninth servo motors 100 and 101 causes the second X-axis actuator 96b and the second Y-axis actuator 98b to operate, and the breaking cutter wheel 103 slightly runs (moves) in a specified direction, so that the breaking cutter wheel 103 exerts a caster effect, and the breaking cutter wheel 103 rotates in the direction around (around the axis) the center axis O2 of the cutter holder (clockwise or counterclockwise), and the rotation (movement) direction of the peripheral edge 112 of the breaking cutter wheel 103 is the running (movement) direction (extension direction of the virtual end tangent) toward the second breaking fixture 94b (breaking cutter holder 102) (rotation direction changing unit (rotation direction changing process)). The travel dimension (movement dimension) of the breaking cutter wheel 103 (the first and second breaking jigs 94a and 94b) in a predetermined direction is 0.8 to 4 mm.

[0193] An example of changing the rotation direction of the cutter wheel 103 is as follows: Fig.30 As shown, from the rotation direction change starting point 109a of the side of the virtual end tangent to the rotation direction change end point 109b, the first breaking clamp 94a (breaking clamp) and the second breaking clamp 94b (breaking clamp) operate (move) in a circular shape (semicircular shape), and the periphery 112 of the breaking cutting wheel 103 rotates 180° and draws a circular trajectory (semicircular trajectory). When the periphery 112 of the breaking cutting wheel 103 is located at the starting point of the virtual end tangent (the rotation direction change end point 109b), the rotation (movement) direction of the periphery 112 of the breaking cutting wheel 103 is toward the operation (movement) direction of the first and second breaking clamps 94a, 94b (the extension direction of the virtual end tangent).

[0194] Another example of changing the rotation direction of the cutting wheel 103 is as follows: Fig.31 , 32 As shown, from the starting point of the virtual end tangent (the starting point 109a for changing the rotation direction) toward the starting point of the virtual end tangent (the end point 109b for changing the rotation direction), the first breaking clamp 94a (breaking clamp) and the second breaking clamp 94b (breaking clamp) operate (move) in a circular shape (perfect circle), and the periphery 112 of the breaking cutting wheel 103 rotates 360° and draws a circular trajectory (perfect circle). When the periphery 112 of the breaking cutting wheel 103 is located at the starting point of the virtual end tangent (the end point 109b for changing the rotation direction), the rotation (movement) direction of the periphery 112 of the breaking cutting wheel 103 is toward the operating (movement) direction of the first and second breaking clamps 94a and 94b (the extension direction of the virtual end tangent). Fig.31 In the figure, the starting point of the virtual end tangent (the starting point 109a of the rotation direction change and the end point 109b of the rotation direction change) is located at the tangent point of the circular trajectory (perfect circle) drawn by the first breaking clamp 94a and the second breaking clamp 94b, and the end tangent K2 extends in the connection direction of the circular trajectory (perfect circle). Fig.32 In the figure, the starting point of the virtual end tangent (the starting point 109a of the rotation direction change and the end point 109b of the rotation direction change) is located on the circular trajectory (perfect circle) drawn by the first breaking clamp 94a and the second breaking clamp 94b, and the end tangent K2 extends radially in the circular trajectory (perfect circle).

[0195] In the glass plate processing system 10 (breaking processing method), the first and second breaking fixtures 94a and 94b are parallel to the upper surfaces 12 of the edge 66b of the glass plates 11a and 11b in the rotation direction change area, so that the upper surfaces 12 of the glass plates 11a and 11b slightly move (draw a circular trajectory) in the specified direction. Therefore, the breaking cutter wheel 103 exerts a caster effect, and the rotation (movement) direction of the peripheral edge 112 of the breaking cutter wheel 103 is changed to the running (movement) direction of the first breaking fixture 94a (breaking cutter bracket 102) (the extension direction of the virtual end tangent). At the same time, the rotation (movement) direction of the peripheral edge 112 of the breaking cutter wheel 103 is changed to the running (movement) direction of the second breaking fixture 94b (breaking cutter bracket 102) (the extension direction of the virtual end tangent).

[0196] After the rotation direction of the peripheral edge 112 of the breaking cutter wheel 103 is changed to the running direction of the first and second breaking clamps 94a and 94b (the extension direction of the virtual end tangent) by the rotation direction changing unit (rotation direction changing process) (after the rotation direction of the breaking cutter wheel 103 is the same as the running direction of the first and second breaking clamps 94a and 94b), the first breaking clamp 94a runs in a straight line from the vicinity of the outer shape cutting line K1 of the glass plates 11a and 11b toward the edge of the glass plates 11a and 11b, and the breaking cutter wheel 103 forms an end tangent K2 (scoring line) on the first (initial) end tangent forming area of ​​the edge 66b of the glass plates 11a and 11b along the running direction of the first breaking clamp 94a (end tangent forming unit (end tangent forming process)).

[0197] In the end tangent line forming unit (end tangent line forming process), the first supporting device 86a moves synchronously with the first breaking device 85a, and at the same time, the first and second supporting surfaces 127a and 127b of the first and second supporting parts 118a and 118b support the lower surface 13 of the edge 66b of the glass plate 11a and 11b extending to the outside of the outer shape cutting line K1, and the breaking cutting wheel 103 of the first breaking fixture 94a forms an end tangent line K2 on the edge 66b of the glass plate 11a and 11b.

[0198] Furthermore, the second breaking fixture 94b runs in a straight line from the vicinity of the outer shape cutting line K1 of the glass plates 11a and 11b toward the edge of the glass plates 11a and 11b, and the breaking cutting wheel 103 forms an end tangent line K2 (scoring line) in the first (initial) end tangent line forming area (prescribed area) of the edge 66b of the glass plates 11a and 11b along the running direction of the second breaking fixture 94b (end tangent line forming unit (end tangent line forming process)). In the end tangent line forming unit (end tangent line forming process), the second supporting device 86b moves synchronously with the second breaking device 85b, and at the same time, the first and second supporting surfaces 127a and 127b of the first and second supporting parts 118a and 118b support the lower surface 13 of the edge 66b of the glass plate 11a and 11b extending to the outside of the outer shape cutting line K1, and the breaking cutting wheel 103 of the second breaking fixture 94b forms an end tangent line K2 on the edge 66b of the glass plate 11a and 11b.

[0199] In addition, the first and second breaking devices 85a, 85b and the first and second supporting devices 86a, 86b operate (move) at the same speed. In the end tangent line forming unit (end tangent line forming process), the first and second breaking jigs 94a, 94b may be operated in a straight line from the edge of the glass plate 11a, 11b toward the vicinity of the outer shape cutting line K1 of the glass plate 11a, 11b, and the breaking cutter wheel 103 may form the end tangent line K2 (scoring line) at the edge 66b of the glass plate 11a, 11b. In the breaking system 10a and the grinding processing method (glass plate processing system 10), since the first and second supporting surfaces 127a and 127b of the first and second supporting parts 118a and 118b support the lower surface 13 of the edge 66b of the glass plates 11a and 11b, elastic deformation of the edge 66b can be prevented, and the end tangent K2 can be reliably formed on the edge 66b of the glass plates 11a and 11b while the edge 66b of the glass plates 11a and 11b is maintained horizontally.

[0200] After the first (initial) end tangent line K2 is formed at the edge 66b of the glass plates 11a and 11b, the support lifting mechanism 104 is operated and the breaking cutter support 102 is raised from the edge end of the edge 66b of the glass plates 11a and 11b (support device lifting unit (support device lifting process)). After the breaking cutter support 102 is raised by the support device lifting unit (support device lifting process), the first and second breaking devices 85a and 85b (first and second breaking clamps 94a and 94b) are moved to the first (initial) pressing area by the operation of the first and second X-axis actuators 96a and 96b and the first and second Y-axis actuators 98a and 98b (breaking device moving unit (breaking device moving process)).

[0201] After the first and second breaking devices 85a and 85b are moved to the first (initial) pressing area by the breaking device moving unit (breaking device moving process), Fig.33 As shown, with the aid of the first pushing component lifting mechanism 106a, the first pushing component 105a of the first and second breaking devices 85a and 85b descends in the upward and downward directions, and the first pushing surface 115a of the first pushing component 105a and the first and second supporting surfaces 127a and 127b of the first and second supporting components 118a and 118b clamp the main body 66a and edge 66b of the glass plates 11a and 11b (glass plate clamping unit (glass plate clamping process)).

[0202] In the glass plate clamping unit (glass plate clamping process), when the first pushing component 105a of the first and second breaking devices 85a and 85b are lowered with the help of the first pushing component lifting mechanism 106a (second lifting mechanism), the first pushing surface 115a formed in a semicircular ring shape of the first pushing component 105a abuts against the upper surface 12 of the edge 66b of the glass plates 11a and 11b that cross the outer shape cutting line K1 and extend to the outer side of the outer shape cutting line K1 and the upper surface 12 of the main body 66a of the glass plates 11a and 11b that extend to the inner side of the outer shape cutting line K1.

[0203] In the glass plate clamping unit (glass plate clamping process), when the first and second support members 118a and 118b are raised by means of the second support member lifting mechanism 119, the second support surface 127b formed in an annular shape of the second support member 118b supports the lower surface 13 of the edge 66b of the glass plates 11a and 11b that cross the outer shape cut-out line K1 and extend to the outer side of the outer shape cut-out line K1 and the lower surface 13 of the main body 66a of the glass plates 11a and 11b that extend to the inner side of the outer shape cut-out line K1, and the first support surface 127a formed in a perfect circle of the first support member 118a supports the lower surface 13 of the main body 66a of the glass plates 11a and 11b that extend to the inner side of the outer shape cut-out line K1, and the lower surface 13 of the edge 66b of the glass plates 11a and 11b that extend to the outer side of the outer shape cut-out line K1 is supported near the outer peripheral edge of the first support surface 127a.

[0204] After the first pressing surface 115a of the first pressing member 105a and the first and second supporting surfaces 127a and 127b of the first and second supporting members 118a and 118b clamp the main body 66a and edge 66b of the glass plates 11a and 11b by the glass plate clamping unit (glass plate clamping process), the second supporting member 118b is lowered in the first (initial) pressing area in the vertical direction by the second supporting member lifting mechanism 119 (second supporting member lowering unit (second supporting member lowering process)). When the first supporting member 118a is lowered, a gap is formed between the lower surface 13 of the glass plates 11a and 11b and the second supporting surface 127b (a step is formed between the first supporting surface 127a and the second supporting surface 127b). In addition, the first pressing surface 115a of the first pressing member 105a and the first supporting surface 127a of the first supporting member 118a maintain the clamping of the main body 66a of the glass plates 11a and 11b.

[0205] After the second supporting member 118b is lowered by the second supporting member lowering means (second supporting member lowering step), the first pressing surface 115a of the first pressing member 105a and the first supporting surface 127a of the first supporting member 118a maintain the clamping of the main body 66a of the glass plates 11a and 11b, and at the same time, the second pressing member 105b is lowered in the vertical direction by the second pressing member lifting mechanism 106b, and the second pressing surface 115b formed in an annular shape of the second pressing member 105b abuts against the upper surface 12 of the edge 66b of the glass plates 11a and 11b extending to the outside of the outer shape cutting line K1, and the second pressing surface 115b of the second pressing member 105b presses the edge 66b of the glass plates 11a and 11b extending to the outside of the outer shape cutting line K1 downwardly. The edge 66b is pushed downwardly by the second pressing surface 115b, and the edge 66b is broken (edge ​​breaking means (edge ​​breaking step)). In the edge breaking means (edge ​​breaking step), the main body 66a and the edge 66b of the glass plates 11a and 11b are cut off. The broken (cut off) edges 66b (peripheral edges) of the glass plates 11a and 11b remain on the belt conveyor 87.

[0206] After the edge 66b is broken in the first (initial) pushing area by the edge breaking unit (edge ​​breaking process), the second supporting member 118b is lifted up and down by the second supporting member lifting mechanism 119, the first pushing member 105a is lifted up and down by the first pushing member lifting mechanism 106a, and the second pushing member 105b is lifted up and down by the second pushing member lifting mechanism 106b.

[0207] After the first and second pressing members 105a, 105b and the second supporting member 118b are raised, the first and second breaking devices 85a, 85b are moved to the second (next) end tangent line forming area of ​​the edge 66b of the glass plates 11a, 11b (breaking device moving unit (breaking device moving process)). The first breaking jig 94a is located at the breaking start position of the second (next) end tangent line forming area outside the width direction of the glass plates 11a, 11b, and the second breaking jig 94b is located at the breaking start position of the second (next) end tangent line forming area outside the width direction of the glass plates 11a, 11b. In addition, the first and second supporting devices 86a, 86b are moved synchronously (synchro) with the first and second breaking devices 85a, 85b to the rotation direction change area of ​​the second (next) end tangent line forming area.

[0208] After the first and second breaking devices 85a, 85b move to the rotation direction changing area of ​​the second (next) end tangent line forming area, the bracket lifting mechanism 104 operates and the breaking cutter bracket 102 descends toward the upper surface 12 of the edge 66b of the glass plate 11a, 11b (support device descending unit (support device descending process)), and the breaking cutter wheel 103 abuts against the upper surface 12 of the glass plate 11a, 11b with a specified pushing force.

[0209] After the breaking cutter bracket 102 is lowered (contacted) to the upper surface 12 of the edge 66b of the glass plate 11a, 11b in the second (next) rotation direction change area through the supporting device lowering unit (supporting device lowering process), as described above, the first and second breaking clamps 94a, 94b (breaking clamps) operate (move) in a circular shape, the breaking cutter wheel 103 exerts a caster effect, and the rotation (movement) direction of the peripheral edge 112 of the breaking cutter wheel 103 is toward the operation (movement) direction of the first and second breaking clamps 94a, 94b (breaking cutter bracket 102) (extension direction of the virtual end tangent) (rotation direction changing unit (rotation direction changing process)), the rotation (movement) direction of the peripheral edge 112 of the breaking cutter wheel 103 is changed to the operation direction (extension direction of the virtual end tangent) of the first and second breaking clamps 94a, 94b (breaking cutter bracket 102).

[0210] After the rotation direction of the peripheral edge 112 of the breaking cutter wheel 103 is changed to the running direction of the first and second breaking clamps 94a and 94b (the extension direction of the virtual end tangent) (after the rotation direction of the breaking cutter wheel 103 is the same as the running direction of the first and second breaking clamps 94a and 94b), the first and second breaking clamps 94a and 94b run in a straight line from the vicinity of the outer shape cutting line K1 of the glass plates 11a and 11b toward the edge of the glass plates 11a and 11b, and the breaking cutter wheel 103 forms an end tangent K2 (end tangent forming unit (end tangent forming process)) on the second (next) end tangent forming area (specified area) of the edge 66b of the glass plates 11a and 11b along the running direction of the first and second breaking clamps 94a and 94b.

[0211] After the end cut line K2 is formed in the second (next) end cut line forming area of ​​the edge 66b of the glass plates 11a and 11b, the breaking cutter support 102 is raised from the edge of the glass plates 11a and 11b by the support lifting mechanism 104 (support device lowering unit (support device lowering process)). After the breaking cutter support 102 is raised, the first and second breaking devices 85a and 85b (first and second breaking jigs 94a and 94b) are moved to the second (next) pressing area (breaking device moving unit (breaking device moving process)).

[0212] After the first and second breaking devices 85a and 85b move to the second (next) pushing area, the first pushing parts 105a of the first and second breaking devices 85a and 85b are lowered in the upward and downward directions with the help of the first pushing part lifting mechanism 106a, and the first pushing surface 115a of the first pushing part 105a and the first and second supporting surfaces 127a and 127b of the first and second supporting parts 118a and 118b in the second (next) pushing area clamp the main body 66a and edge 66b of the glass plates 11a and 11b (glass plate clamping unit (glass plate clamping process)).

[0213] After the first pushing surface 115a of the first pushing member 105a and the first and second supporting surfaces 127a, 127b of the first and second supporting members 118a, 118b clamp the main body 66a and edge 66b of the glass plates 11a, 11b, the second supporting member lifting mechanism 119 lowers the second supporting member 118b in the vertical direction in the second (next) pushing area (second supporting member lowering unit (second supporting member lowering process)).

[0214] After the second supporting member 118b is lowered, the first pressing surface 115a of the first pressing member 105a and the first supporting surface 127a of the first supporting member 118a maintain the clamping of the main body 66a of the glass plates 11a and 11b, and the second pressing member lifting mechanism 106b lowers the second pressing member 105b in the vertical direction, and the second pressing surface 115b of the second pressing member 105b in the second (next) pressing area presses the edge 66b of the glass plates 11a and 11b extending to the outside of the outer shape cutting line K1 downward. The edge 66b is broken by the second pressing surface 115b pushing the edge 66b downward (edge ​​breaking unit (edge ​​breaking process)). The broken (cut) edge 66b (peripheral edge) of the glass plates 11a and 11b remains on the belt conveyor 87.

[0215] In the grinding processing system 10a and the grinding processing method (glass plate processing system 10), after the breaking cutter wheel 103 and the first and second pushing members 105a and 105b are raised by the support lifting mechanism 104 and the first and second pushing member lifting mechanisms 106a and 106b, the first and second breaking devices 85a and 85b are moved in the front and rear direction (horizontal direction) and the width direction (horizontal direction) on the upper surface 12 side of the glass plates 11a and 11b (breaking device moving unit (breaking device moving process)), and after the second supporting member 118b is raised by the second supporting member lifting mechanism 119, the first and second breaking devices 85a and 85b are connected to the first and second breaking devices 85a and 85b on the lower surface 13 side of the glass plates 11a and 11b. The breaking devices 85a and 85b move synchronously (synchro) in the front-rear direction (horizontal direction) and the width direction (horizontal direction) (support device moving unit (support device moving process)). After the first and second supporting devices 86a and 86b are moved synchronously with the first and second breaking devices 85a and 85b by means of the breaking device moving unit (breaking device moving process) and the supporting device moving unit (support device moving process), the first breaking device 85a and the first supporting device 86a cooperate with each other, while the second breaking device 85b and the second supporting device 86b cooperate to implement the end tangent line forming unit (end tangent line forming process), the glass plate clamping unit (glass plate clamping process) and the edge breaking unit (edge ​​breaking process).

[0216] By repeating the above-mentioned procedure, all the edge portions 66b of the glass plates 11a and 11b having the end cut lines K2 are broken. Fig.30 In the glass plates 11a and 11b shown, although the first to third end tangent lines K2 are formed by the first breaking fixture 94a and the first to third end tangent lines K2 are formed by the second breaking fixture 94b, the number of end tangent lines K2 is not particularly limited and is determined by the size (area) and thickness of the glass plates 11a and 11b and the shape of the main body of the glass plates 11a and 11b made by the outer cutting line K1.

[0217] After the breaking process is completed and the broken glass plates 11a and 11b are lifted upward by the third glass plate support 40c, the controller transmits a drive signal (ON signal) to the control unit of the conveyor drive motor 88. The control unit of the conveyor drive motor 88 that receives the drive signal (ON signal) drives the belt conveyor 87. The belt conveyor 87 moves from one side to the other side in the width direction. With the movement of the belt conveyor 87 in the width direction, the broken edge 66b (peripheral edge) of the glass plates 11a and 11b remaining on the belt conveyor 87 gradually moves from one side to the other side in the width direction, and the edge 66b falls from the belt conveyor 87 and is stored (discarded) in a trash can (not shown).

[0218] After the breaking process of the glass plates 11a and 11b is completed, the main body 66a of the glass plates 11a and 11b after the breaking process is transported from the breaking process area 21 to the grinding process area 22 by means of the third glass plate support 40c, and the third glass plate support 40c is lowered and the main body 66a of the glass plates 11a and 11b is placed on the grinding process table 128, and the lower surface 13 of the main body 66a abuts against the table suction cup 130 (suction pad). In addition, by starting the air vacuum pump, the magnetic hammer component 47 is sucked and held by the magnetic hammer component holding suction cup 49, and the magnetic hammer component holding mechanism 44 (magnetic hammer component 47) is raised by the lifting mechanism 45. Furthermore, the fourth glass plate support 40d provided with the magnetic hammer component holding suction cup 49 for sucking and holding the magnetic hammer component 47 is located above the unloading area 23.

[0219] After the main body 66a of the glass plates 11a and 11b is placed on the grinding table 128, the controller transmits a drive signal to the control unit of the vacuum mechanism of the grinding table 128. The control unit of the vacuum mechanism that receives the drive signal drives the vacuum mechanism. With the drive of the vacuum mechanism, the main body 66a of the glass plates 11a and 11b is sucked and held by the table suction cup 130 (sucking pad) (grinding table 128) (first fixing unit (first fixing process)).

[0220] After the main body 66a of the glass plates 11a and 11b is sucked and held by the table suction cup 130 (grinding table 128), the controller transmits a stop signal (OFF signal) to the control unit of the vacuum mechanism of the third glass plate holder 40c, and at the same time, transmits an ascending signal (ON signal) to the control unit of the holder lifting mechanism (elevating mechanism). The control unit of the vacuum mechanism of the third glass plate holder 40c, which receives the stop signal (OFF signal), stops the vacuum mechanism and releases the suction of the main body 66a of the glass plates 11a and 11b by the holder suction cup 42. The control unit of the holder lifting mechanism, which receives the ascending signal (ON signal), ascends the pad setting plate 41 (the third glass plate holder 40c).

[0221] Next, the controller transmits a retract signal (ON signal) to the control unit of the second servo motor 39. The control unit of the second servo motor 39, which receives the retract signal (ON signal), drives the second servo motor 39. By the rotation of the shaft of the second servo motor 39, the slider moves in the front-to-rear direction from the front to the rear of the second guide frame 35, thereby the fourth glass plate holder 40d moves from the unloading area 23 to the grinding processing area 22. In addition, the first glass plate holder 40a moves from the cutting processing area 20 to the loading area 19, the second glass plate holder 40b moves from the breaking processing area 21 to the cutting processing area 20, and the third glass plate holder 40c moves from the grinding processing area 22 to the breaking processing area 21.

[0222] When the fourth glass plate support 40d moves toward the grinding processing area 22 and the magnetic hammer component holding mechanism 44 (magnetic hammer component holding suction cup 49) moves to the center of the main body 66a of the glass plates 11a and 11b adsorbed and held by the table suction cup 130, the controller transmits an OFF signal to the control unit of the second servo motor 39. The control unit of the second servo motor 39 that receives the OFF signal stops the second servo motor 39. The magnetic hammer component holding mechanism 44 (the magnetic hammer component 47 adsorbed and held by the magnetic hammer component holding suction cup 49) is positioned directly above the center of the main body 66a (positioning unit (positioning process)).

[0223] After the magnetic hammer component 47 is positioned above the main body 66a and in the center of the main body 66a by the positioning unit, the controller transmits a descending signal (ON signal) to the control unit of the bracket lifting mechanism. The control unit of the bracket lifting mechanism that receives the descending signal (ON signal) lowers the pad setting plate 41 (the fourth bracket 40d of the glass plate). After the pad setting plate 41 is lowered, the controller transmits a descending signal (ON signal) to the control unit of the lifting mechanism 45 (cylinder) provided on the fourth bracket 40d of the glass plate. The control unit of the lifting mechanism 45 that receives the descending signal (ON signal) lowers the magnetic hammer component holding mechanism 44 to the lowest limit with the aid of the lifting mechanism 45. When the magnetic hammer component holding mechanism 44 descends, the magnetic hammer component 47 adsorbed and held by the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 descends toward the central upper surface of the main body 66a of the glass plates 11a, 11b, and the magnetic hammer component 47 is placed directly above the magnet 131 in a manner such that the magnet 131 and the magnetic hammer component 47 clamp the main body 66a (first descending unit (first descending process)).

[0224] When the magnetic hammer component holding mechanism 44 (magnetic hammer component 47) descends and the magnetic hammer component 47 abuts against the central upper surface of the main body 66a, the opposing surface 51 (pushing surface) of the magnetic hammer component 47 is adsorbed on the magnet 131 located directly below the workbench suction cup 130, and the adsorption surface 134 of the magnet 131 located directly below the lower surface 13 of the main body 66a is used to abut against the upper surface 12 of the main body 66a and the opposing surface 51 of the magnetic hammer component 47 adsorbed on the magnet 131 to clamp and fix the main body (second fixing unit (second fixing process)). In addition, when an electromagnet is used as the magnet 131, at the same time as the pad setting plate 41 starts to descend or after the magnetic hammer component 47 abuts against the central upper surface of the main body 66a (before the grinding process of the periphery of the main body 66a of the glass plates 11a and 11b begins), the electromagnet (magnet 131) is energized to generate a magnetic force (energization start unit (energization start process)).

[0225] After the facing surface 51 of the magnetic hammer component 47 is adsorbed on the adsorption surface 134 of the magnet 131 (after the magnetic hammer component 47 is placed directly above the magnet 131), the controller transmits an OFF signal to the control unit of the vacuum mechanism (air vacuum pump) of the magnetic hammer component holding mechanism 44. The control unit of the vacuum mechanism that receives the OFF signal turns off (OFF) the vacuum mechanism, thereby eliminating the adsorption force of the magnetic hammer component holding suction cup 49 and releasing the adsorption of the magnetic hammer component 47 to the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49.

[0226] Next, the controller transmits the rising signal (ON signal) to the control unit of the lifting mechanism 45 (cylinder) provided on the fourth support 40d of the glass plate, and transmits the rising signal (ON signal) to the control unit of the support lifting mechanism. The control unit of the lifting mechanism 45 receiving the rising signal causes the magnetic hammer component holding mechanism 44 to rise to the upper limit (first rising unit) above the magnetic hammer component 47 (from the upper surface 12 of the main body 66a upward) through the lifting mechanism 45. The control unit of the support lifting mechanism receiving the rising signal causes the pad setting plate 41 (the fourth support 40d of the glass plate) to rise through the support lifting mechanism. The magnetic hammer component 47 attracted by the magnet 131 remains on the upper surface 12 of the main body 66a of the glass plates 11a and 11b.

[0227] After the magnetic hammer component holding mechanism 44 is raised above the magnetic hammer component 47 and the pad setting plate 41 (the fourth support 40d of the glass plate) is raised, the controller transmits a retract signal (ON signal) to the control unit of the first servo motor 34. The control unit of the first servo motor 34, which receives the retract signal (ON signal), drives the first servo motor 34. With the rotation of the shaft of the first servo motor 34, the first slider is moved from the front to the rear in the front-to-back direction of the first guide frame 30, thereby the grinding device 129 moves in the rear of the front-to-back direction in the grinding processing area 22 together with the first operating frame 32, and the grinding device 129 is located outside the first corner 18a (front side edge) of the main body 66a of the glass plates 11a and 11b in the width direction (grinding processing start position). In addition, the grinding device 129 and the cutting device 65 move synchronously at the peripheral edge (side edge, front and rear end edge) of the main body 66a of the glass plates 11a and 11b.

[0228] After the grinding device 129 is located outside the first corner 18a of the main body 66a of the glass plates 11a and 11b in the width direction (grinding process start position), the controller transmits a stop signal (OFF signal) to the control unit of the first servo motor 34, and at the same time, transmits a drive signal (ON signal) to the control unit of the fourteenth servo motor 136. The control unit of the first servo motor 34 that receives the stop signal (OFF signal) stops the first servo motor 34, and the control unit of the fourteenth servo motor 136 that receives the drive signal (ON signal) drives the fourteenth servo motor 136. By rotating the shaft of the fourteenth servo motor 136, the slider 73b is moved from the other side edge portion 58b of the grinding process area 22 to the one side edge portion 58a, and the feed screw 70b is moved in the width direction, thereby the grinding process table 128 is moved in the width direction from the side of the other side edge portion 58b of the grinding process area 22 to the side of the one side edge portion 58a, and the grinding wheel 143 of the grinding device 129 is located at the first corner 18a of the main body 66a of the glass plates 11a and 11b. The first corner 18a of the main body 66a of the glass plates 11a and 11b enters the slit 147 of the cover plate 145 of the grinding fixture 137.

[0229] After the grinding wheel 143 of the grinding device 129 is located at the first corner 18a of the glass plates 11a, 11b, the controller transmits the drive signal (ON signal) and the NC control signal to the control unit of the fifteenth to seventeenth servo motors 138 to 140 of the grinding device 129 and the control unit of the spindle motor 146, and transmits the retract signal (ON signal) and the NC control signal to the control unit of the first servo motor 34, and transmits the NC control signal to the control unit of the fourteenth servo motor 136. The control units of the fifteenth to seventeenth servo motors 138 to 140 and the spindle motor 146, the first servo motor 34, and the fourteenth servo motor 136, which receive the drive signal (ON signal) and the NC control signal, drive the fifteenth to seventeenth servo motors 138 to 140, the spindle motor 146, the first servo motor 34, and the fourteenth servo motor 136, and perform NC-controlled contour control movement on the side edge of one side (the side edge of one side) of the main body 66a of the glass plates 11a, 11b, bite into the side surface (cylindrical portion) of the rotating disc-shaped grinding wheel of the grinding wheel 143, and grind the side edge of one side (the side edge of one side) of the main body 66a of the glass plates 11a, 11b (grinding unit (grinding process)).

[0230] During the grinding process (cut-in process), the control unit of the first servo motor 34 receiving the retreat signal (ON signal) drives the first servo motor 34 and moves the grinding device 129 to the rear in the front-rear direction in the grinding process area 22, and the control unit of the fourteenth servo motor 136 drives the fourteenth servo motor 136 to move the grinding device 129 back and forth in the width direction in the grinding process area 22. The grinding wheel 143 of the grinding device 129 grinds the vicinity of one side edge (one side edge portion) of the main body 66a of the glass plates 11a and 11b along the edge (outline cut-out line K1) of the main body 66a of the glass plates 11a and 11b, and moves from the first corner 18a to the second corner 18b of the glass plates 11a and 11b.

[0231] After the grinding process of the side edge (side edge) of one side of the main body 66a of the glass plates 11a and 11b by the grinding wheel 143 of the grinding device 129 is completed and the grinding wheel 143 is located at the second corner 18b of the main body 66a of the glass plates 11a and 11b, the grinding table 128 moves in the width direction from one side of the side edge 58a of the grinding process area 22 toward the other side of the side edge 58b. As the grinding table 128 moves in the width direction, the side surface (cylindrical portion) of the rotating disc-shaped grinding wheel of the grinding wheel 143 is bitten into, and the rear end edge (rear end edge) of the main body 66a of the glass plates 11a and 11b is ground (grinding unit (grinding process)).

[0232] During the grinding process (cut-in process), the control unit of the fourteenth servo motor 136 drives the fourteenth servo motor 136 to move the grinding table 128 in the width direction in the grinding process area 22, and the control unit of the first servo motor 34 drives the first servo motor 34 to move the grinding device 129 back and forth in the grinding process area 22. The grinding wheel 143 of the grinding device 129 grinds the vicinity of the rear end edge (rear end edge) of the main body 66a of the glass plates 11a and 11b along the edge (outline cut-out line K1) of the main body 66a of the glass plates 11a and 11b, and moves from the second corner 18b toward the third corner 18c of the main body 66a of the glass plates 11a and 11b.

[0233] After the grinding process of the rear end edge (rear end edge) of the main body 66a of the glass plates 11a and 11b by the grinding wheel 143 of the grinding device 129 is completed and the grinding wheel 143 is located at the third corner 18c of the main body 66a of the glass plates 11a and 11b, the grinding device 129 moves forward in the front-to-rear direction. As the grinding device 129 moves forward in the front-to-rear direction, the side surface (cylindrical portion) of the rotating disc-shaped grinding wheel of the grinding wheel 143 is bitten into and the second side edge (second side edge) of the main body 66a of the glass plates 11a and 11b is ground (grinding unit (grinding process)).

[0234] During the grinding process (cut-in process), the control unit of the first servo motor 34 drives the first servo motor 34 to move the grinding device 129 forward in the front-rear direction in the grinding process area 22, and the control unit of the fourteenth servo motor 136 drives the fourteenth servo motor 136 to move the grinding process table 128 back and forth in the width direction in the grinding process area 22. The grinding wheel 143 of the grinding device 129 grinds the vicinity of the second side edge (second side edge portion) of the main body portion 66a of the glass plates 11a and 11b along the edge (outline cut-out line K1) of the main body portion 66a of the glass plates 11a and 11b, and moves from the third corner portion 18c toward the fourth corner portion 18d of the main body portion 66a of the glass plates 11a and 11b.

[0235] After the grinding process of the second side edge (second side edge) of the main body 66a of the glass plates 11a and 11b by the grinding wheel 143 of the grinding device 129 is completed and the grinding wheel 143 is located at the fourth corner 18d of the main body 66a of the glass plates 11a and 11b, the grinding processing table 128 moves in the width direction from the side of the side edge 58b on the other side of the grinding processing area 22 toward the side of the side edge 58a on one side. As the grinding processing table 128 moves in the width direction, the side surface (cylindrical portion) of the rotating disc-shaped grinding wheel of the grinding wheel 143 is bitten into, and the front end edge (front end edge) of the main body 66a of the glass plates 11a and 11b is ground (grinding processing unit (grinding processing step)).

[0236] During the grinding process (cut-in process), the control unit of the fourteenth servo motor 136 drives the fourteenth servo motor 136 to move the grinding table 128 in the width direction in the grinding process area 22, and the control unit of the first servo motor 34 drives the first servo motor 34 to move the grinding device 129 back and forth in the grinding process area 22. The grinding wheel 143 of the grinding device 129 grinds the vicinity of the front edge (front edge) of the main body 66a of the glass plates 11a and 11b along the edge (outline cut-out line K1) of the main body 66a of the glass plates 11a and 11b, and moves from the fourth corner 18d of the main body 66a of the glass plates 11a and 11b toward the first corner 18a. When the grinding process performed by the grinding wheel 143 of the grinding device 129 on the front end edge (front end edge) of the main body 66a of the glass plates 11a and 11b is completed, the grinding device 129 moves to the outside in the width direction of the first corner 18a (front end edge) of the main body 66a of the glass plates 11a and 11b (grinding process starting position) and waits.

[0237] In the grinding processing area 22, for example, by means of the first positioning unit (first positioning step), one side in the width direction of the large-sized (large-area) glass plate 11a whose upper surface 12 and lower surface 13 are processed first, is located at the outermost edge in the width direction (the side edge 14 of one side in the glass plate 11a shown in the figure) of the side edge 14 extending in the front-rear direction, so that one side in the width direction of the small-sized (small-area) glass plate 11b whose upper surface 12 and lower surface 13 are processed later, is located at the outermost edge in the width direction (the side edge 14 of one side in the glass plate 11a shown in the figure), and the ... , the outermost edge of the side edge 14 extending in the front-back direction (the side edge 14 on one side in the glass plate 11b shown in the figure) located on the outermost side in the width direction is positioned (aligned) to position the glass plates 11a and 11b having different areas of the upper surface 12 and the lower surface 13, and, by means of the second positioning unit (second positioning step), the position of the front-back center O1 (the center line L2 that divides the front-back dimension of the glass plate 11a into two and extends in the width direction) of the side edge 14 extending in the front-back direction on one side in the width direction of the large-sized glass plate 11a processed previously is aligned. On the second positioning reference L2 (the virtual positioning second reference line), the front-to-back center O1 (the center line L2 that divides the front-to-back dimension of the glass plate 11b into two and extends in the width direction) of the side edge 14 extending in the front-to-back direction on one side of the width direction of the glass plate 11b of the small size to be processed later is positioned (aligned), and after the glass plates 11a and 11b of different areas of the upper surface 12 and the lower surface 13 are positioned, the glass plates 11b of different areas to be processed later are ground, and the movement of the grinding device 129 until it reaches the side edge 14 of the large-sized glass plate 11a The moving distance (the moving distance of the grinding processing worktable 128 in the width direction) is equal to the moving distance (the moving distance of the grinding processing worktable 128 in the width direction) until the grinding device 129 reaches the side edge 14 of the small-sized glass plate 11b, and the moving distance of the grinding device 129 from the outermost edge (side edge 14) of the large-sized glass plate 11a to return to the outer side in the width direction of the glass plate 11a is equal to the moving distance of the grinding device 129 from the outermost edge (side edge 14) of the small-sized glass plate 11b to return to the outer side in the width direction of the glass plate 11b.

[0238] As the moving distance of the grinding device 129 until it reaches the outermost edge (side edge 14) of the small-sized glass plate 11b becomes shorter, the moving distance of the grinding device 129 from the outermost edge (side edge 14) of the small-sized glass plate 11b to returning to the outer side in the width direction of the glass plate becomes shorter. As the arrival time (non-processing time) of the grinding device 129 until it reaches the outermost edge (side edge 14) of the small-sized glass plate 11b becomes shorter, the return time of the grinding device 129 from the outermost edge (side edge 14) of the small-sized glass plate 11b to returning to the outer side in the width direction of the glass plate becomes shorter.

[0239] After the grinding process of the main body 66a of the glass plates 11a and 11b is completed, the controller transmits a descending signal (ON signal) to the control unit of the lifting mechanism 45 (cylinder) provided on the fourth support 40d of the glass plate. The control unit of the lifting mechanism 45 which receives the descending signal (ON signal) causes the magnetic hammer component holding mechanism 44 to descend through the lifting mechanism 45. The magnetic hammer component holding mechanism 44 descends toward the magnetic hammer component 47 remaining on the upper surface 12 of the main body 66a of the glass plates 11a and 11b. When the magnetic hammer component holding mechanism 44 descends to the lowest limit, the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 abuts against the adsorption surface 50 of the magnetic hammer component 47.

[0240] After the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 abuts against the adsorption surface 50 of the magnetic hammer component 47 (after the peripheral grinding process of the main body 66a of the glass plates 11a and 11b is completed), the controller transmits the adsorption signal (ON signal) to the control unit of the vacuum mechanism (air vacuum pump) of the magnetic hammer component holding mechanism 44. The control unit of the vacuum mechanism that receives the adsorption signal (ON signal) turns on (starts) the air vacuum pump. When the air vacuum pump becomes ON, the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 generates negative pressure, the adsorption surface 50 generates adsorption force, and the adsorption surface 50 of the magnetic hammer component 47 is adsorbed and held on the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 (second descending unit (second descending process)).

[0241] After the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 adsorbs and holds the adsorption surface 50 of the magnetic hammer component 47, the controller transmits an ascending signal (ON signal) to the control unit of the lifting mechanism 45. The control unit of the lifting mechanism 45, which receives the ascending signal (ON signal), raises the magnetic hammer component holding mechanism 44 through the lifting mechanism 45. In addition, the adsorption force (output of the air vacuum pump) of the adsorption holding surface 48 is adjusted so that the adsorption force (attractive force) of the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 is greater than the adsorption force of the magnet 131.

[0242] When the magnetic hammer component 47 adsorbed on the adsorption holding surface 48 of the magnetic hammer component holding suction cup 49 is pulled upward by the lifting mechanism 45, the adsorption of the opposing surface 51 of the magnetic hammer component 47 relative to the adsorption surface 134 of the magnet 131 is released, and the magnetic hammer component 47 and the magnetic hammer component holding suction cup 49 gradually rise upward from the upper surface 12 of the main body 66a of the glass plates 11a and 11b in a state where the magnetic hammer component 47 is adsorbed on the adsorption holding surface 48 (second ascending means). In addition, when the magnet 131 is an electromagnet, after the adsorption holding surface 48 of the magnetic hammer component holding mechanism 44 adsorbs and holds the adsorption surface 50 of the magnetic hammer component 47 through the second descending means (second descending process), the energization of the electromagnet is stopped to eliminate the magnetic force of the electromagnet (energization stopping means).

[0243] After the magnetic hammer component holding mechanism 44 rises to the uppermost limit, the controller transmits a forward signal (ON signal) to the control unit of the second servo motor 39. The control unit of the second servo motor 39 that receives the forward signal (ON signal) drives the second servo motor 39. By rotating the shaft of the second servo motor 39, the slider moves from the rear of the second guide frame 35 to the front in the front-rear direction, thereby moving the fourth glass plate bracket 40d to the front in the front-rear direction.

[0244] The fourth glass plate holder 40d moves forward in the front-rear direction, and when the holder suction cup 42 (adsorption pad) moves to the center of the main body 66a of the glass plates 11a and 11b adsorbed and held by the table suction cup 130, the controller transmits a stop signal (OFF signal) to the control unit of the second servo motor 39. The control unit of the second servo motor 39 that receives the stop signal (OFF signal) stops the second servo motor 39. The table suction cup 130 is located directly below the center of the main body 66a.

[0245] After the workbench suction cup 130 is located below the main body 66a and in the center of the main body 66a, the controller transmits a descending signal (ON signal) to the control unit of the bracket lifting mechanism. The control unit of the bracket lifting mechanism, which receives the descending signal (ON signal), lowers the pad setting plate 41 (bracket suction cup 42) of the fourth bracket 40d of the glass plate through the bracket lifting mechanism. After the pad setting plate 41 is lowered and the bracket suction cup 42 abuts against the upper surface 12 in the center of the main body 66a of the glass plates 11a and 11b, the controller transmits a suction signal (ON signal) to the control unit of the vacuum mechanism (air vacuum pump). The control unit of the vacuum mechanism (air vacuum pump) that receives the suction signal (ON signal) starts the air vacuum pump.

[0246] The start of the air vacuum pump adsorbs and holds the upper surface 12 of the main body 66a on the bracket suction cup 42. After the main body 66a of the glass plates 11a and 11b is adsorbed and held by the bracket suction cup 42, the controller transmits a stop signal (OFF signal) to the control unit of the vacuum mechanism that generates negative pressure on the workbench suction cup 130, and transmits an ascending signal (ON signal) to the control unit of the bracket lifting mechanism. The control unit of the vacuum mechanism that receives the stop signal (OFF signal) stops the vacuum mechanism to eliminate the adsorption force of the workbench suction cup 130, and the control unit of the bracket lifting mechanism that receives the ascending signal (ON signal) starts the bracket lifting mechanism to raise the bracket suction cup 42 (the fourth bracket 40d of the glass plate) that adsorbs and holds the main body 66a.

[0247] After the holder suction cup 42 (the fourth holder 40d for the glass plate) rises to the uppermost limit, the controller transmits a forward signal (ON signal) to the control unit of the second servo motor 39. The control unit of the second servo motor 39 that receives the forward signal (ON signal) drives the second servo motor 39. By rotating the shaft of the second servo motor 39, the slider moves from the rear to the front of the second guide frame 35 in the front-rear direction, thereby moving the fourth holder 40d for the glass plate in the front-rear direction toward the unloading area (moving unit (moving process)).

[0248] The fourth glass plate support 40d moves forward in the front-rear direction, and the main body 66a of the glass plates 11a and 11b after the grinding process is transported from the grinding process area 22 to the unloading area 23 by means of the fourth glass plate support 40d. When the main body 66a of the glass plates 11a and 11b is transported to the unloading area, the controller transmits a stop signal (OFF signal) to the control unit of the second servo motor 39. The control unit of the second servo motor 39 that receives the stop signal (OFF signal) stops the second servo motor 39. In the unloading area 23, the main body 66a of the glass plates 11a and 11b that have completed the cutting process, the breaking process, and the grinding process is moved forward from the rear end of the unloading area 23 to the front end by the unloading conveyor 150, and the main body 66a of the glass plates 11a and 11b that have completed each process is unloaded from the unloading area 23.

[0249] In addition, when the main body 66a of the glass plates 11a and 11b that have completed each process is located on the unloading conveyor 150 of the unloading area 23, the main body 66a of the glass plates 11a and 11b that have completed the grinding process is located on the grinding processing table 128 of the grinding processing area 22, the main body 66a of the glass plates 11a and 11b that have completed the breaking process is located on the breaking processing table 84 of the breaking processing area 21, and the glass plates 11a and 11b that have completed the cutting process are located on the cutting processing table 64 of the cutting processing area 20, and the glass plates 11a and 11b before processing that have been positioned by the first positioning unit (first positioning step) and the second positioning unit (second positioning step) are located on the loading conveyor 53 of the loading area 19. In this way, in the breaking system 10a and the grinding processing method (glass plate processing system 10), a plurality of glass plates are sequentially transported from the loading area 19 to the unloading area 23, and the processing of the plurality of glass plates 11a and 11b is continuously performed.

[0250] In the breaking system 10a and the grinding method (glass plate processing system 10), before the grinding process starts on the periphery of the main body 66a of the glass plates 11a and 11b, the table suction cup 130 (adsorption pad) abuts against the lower surface 13 of the main body 66a and adsorbs and holds the lower surface 13 of the main body 66a, and before the grinding process starts on the periphery of the main body 66a of the glass plates 11a and 11b, the main body 66a is clamped and fixed by the magnet 131 (permanent magnet or electromagnet) located just below the lower surface 13 of the main body 66a and the magnetic hammer component 47 abutting against the upper surface 12 of the main body 66a and adsorbed by the magnet 131. Therefore, not only the glass plates 11a and 11b are broken by the table suction cup 130, but also the main body 66a is fixed by the magnet 131 (permanent magnet or electromagnet) located just below the lower surface 13 of the main body 66a and the magnetic hammer component 47 abutting against the upper surface 12 of the main body 66a and adsorbed by the magnet 131. The main body 66a of the glass plates 11a and 11b is placed and fixed on the grinding workbench 128, and the main body 66a of the glass plates 11a and 11b is clamped by a magnet 131 located in the center of the main body 66a and directly below the lower surface 13 of the main body 66a, and a magnetic hammer component 47 abutting against the upper surface 12 of the main body 66a and adsorbed on the magnet 131, so as to strengthen the fixation of the main body 66a of the glass plates 11a and 11b relative to the grinding workbench 128. Even if the main body 66 is a relatively small-sized (small-area) glass plate 11a or 11b, the main body 66a of the glass plates 11a and 11b can be firmly fixed on the grinding workbench 128 by the magnet 131 and the magnetic hammer component 47 together with the workbench suction cup 130.

[0251] In the breaking system 10a and the grinding method (glass plate processing system 10), when the side surface (cylindrical portion) of the rotating disc-shaped grinding wheel 143 of the grinding device 129 (grinding mechanism) is bitten into the peripheral edge grinding of the main body 66a of the glass plates 11a and 11b, the main body 66a of the glass plates 11a and 11b can be prevented from sliding sideways (lateral deviation) on the grinding table 128, and the peripheral edge of the main body 66a can be ground while the main body 66a of the glass plates 11a and 11b is securely fixed on the grinding table 128. The breaking system 10a and the grinding method (glass plate processing system 10) can maintain the grinding speed and can complete the grinding of the glass plates 11a and 11b into a specified shape according to the design.

[0252] In the breaking system 10a and the grinding processing method (glass plate processing system 10), after the grinding processing of the periphery of the main body 66a of the glass plates 11a and 11b is completed, the magnetic hammer component holding mechanism 44 provided on the fourth bracket 40d of the glass plate descends toward the upper surface 12 of the main body 66a of the glass plates 11a and 11b and holds the magnetic hammer component 47. After holding the magnetic hammer component 47, the magnetic hammer component holding mechanism 44 provided on the fourth bracket 40d of the glass plate rises upward from the upper surface 12 of the main body 66a and releases the adsorption of the magnetic hammer component 47 on the magnet 131 (permanent magnet or electromagnet). Therefore, the clamping of the magnet 131 and the magnetic hammer component 47 on the main body 66a of the glass plates 11a and 11b can be reliably released, and the main body 66a of the glass plates 11a and 11b whose periphery has been ground can be transported to the next unloading area 23 (processing completion area).

[0253] In addition, in the case where the magnet 131 is an electromagnet, after the grinding process of the periphery of the main body 66a of the glass plates 11a, 11b is completed and the magnetic hammer component holding mechanism 44 holds the magnetic hammer component 47, the power supply to the electromagnet is stopped to eliminate the magnetic force of the electromagnet, thereby releasing the adsorption of the magnetic hammer component 47 on the electromagnet, and the clamping of the electromagnet and the magnetic hammer component 47 on the main body 66a of the glass plates 11a, 11b can be easily released, and the main body 66a of the glass plates 11a, 11b with the ground periphery can be transported to the next unloading area 23 (processing completion area).

[0254] In the breaking system 10a and the grinding method (glass plate processing system 10), after the grinding of the periphery of the main body 66a of the glass plates 11a and 11b is completed, the engagement between the magnet 131 (permanent magnet or electromagnet) and the magnetic hammer component 47 is released to transport the main body 66a of the glass plates 11a and 11b to the unloading area, and the main body 66a of the next glass plate 11a and 11b that has not been ground is placed and fixed on the grinding workbench 128, and the periphery of the main body 66a is ground. Therefore, the main body 66a of the glass plates 11a and 11b can be continuously ground, and multiple glass plates 11a and 11b can be effectively ground.

[0255] In the breaking system 10a and the grinding method (glass plate processing system 10), the magnetic hammer component 47 is made of any one of the metals such as iron, nickel, and cobalt, so the magnetic hammer component 47 is easily adsorbed on the magnet 131 (permanent magnet or electromagnet), and the main body 66a of the glass plates 11a and 11b is clamped by using the magnet 131 with an adsorption surface 134 of a specified area located in the center 133 of the workbench suction cup 130 and the magnetic hammer component 47 of a specified weight adsorbed on the magnet 131. By using the magnet 131 with an adsorption surface 134 of a specified area and the magnetic hammer component 47 of a specified weight made of any one of the metals such as nickel and cobalt, the fixation of the main body 66a of the glass plates 11a and 11b relative to the grinding workbench 128 can be reliably strengthened.

[0256] In the breaking system 10a and the grinding method (glass plate processing system 10), the breaking cutter wheel 103 which is lowered in the vertical direction by the support lifting mechanism 104 forms the end tangent line K2 on the edge 66b of the glass plates 11a and 11b. After the end tangent line K2 is formed on the edge 66b of the glass plates 11a and 11b, the breaking cutter wheel 103 is raised in the vertical direction by the support lifting mechanism 104, and the first pushing member 105a is lowered in the vertical direction by the first pushing member lifting mechanism 106a, and the upper surface 12 of the edge 66b of the glass plates 11a and 11b extending to the outer side of the outer shape cutting line K1 and the glass plates 11a and 11b extending to the inner side of the outer shape cutting line K1 are moved. The semi-circular first pushing surface 115a of the first pushing member 105a abutted against the upper surface 12 of the main body 66a of the glass plates 11a and 11b and the first and second supporting surfaces 127a and 127b of the first and second supporting members 118a and 118b clamp the main body 66a and the edge 66b of the glass plates 11a and 11b. After the first pushing member 105a and the first and second supporting members 118a and 118b clamp the main body 66a and the edge 66b, the second supporting member lifting mechanism 119 lowers the second supporting member 118b in the vertical direction, and the main body 66a is clamped by the first pushing surface 115a of the first pushing member 105a and the first supporting surface 127a of the first supporting member 118a, and the second pushing member The lifting mechanism 106b causes the second pushing member 105b to descend in the vertical direction, and the second pushing surface 115b of the second pushing member 105b pushes downward the edge 66b of the glass plates 11a and 11b extending to the outside of the outer shape cutting line K1, and breaks the edge 66b, so that the first pushing surface 115a of the first pushing member 105a and the first supporting surface 127a of the first supporting member 118a clamp the main body 66a of the glass plates 11a and 11b, and the first supporting surface 127a of a predetermined area formed in a perfect circle supports the lower surface 13 of the main body 66a of the glass plates 11a and 11b extending to the vicinity of the inner side of the outer shape cutting line K1, and the outer peripheral edge of the first supporting surface 127a supports the main body 66a of the glass plates 11a and 11b extending to the vicinity of the inner side of the outer shape cutting line K1. The lower surface 13 of the edge 66b of the glass plates 11a, 11b near the outer side of the outer shape cut-out line K1 is fixed firmly to the main body 66a of the glass plates 11a, 11b by the first pressing member 105a and the first supporting member 118a. Therefore, even if the second pressing surface 115b of the second pressing member 105b presses downward the edge 66b of the glass plates 11a, 11b extending to the outer side of the outer shape cut-out line K1 so that the pressing force of the second pressing member 105b acts on the edge 66b, elastic deformation of the main body 66a and the edge 66b of the glass plates 11a, 11b extending to the outer side of the outer shape cut-out line K1 can be prevented, and the main body 66a and the edge 66b will not bend upward.The edge 66b of the glass plates 11a and 11b at the outer cut line K1 and the end cut line K2 can be broken smoothly and reliably.

[0257] In the breaking system 10a and the grinding method (glass plate processing system 10), since the breaking cutter wheel 103 has a cutter wheel axis O3 radially outwardly eccentric relative to the cutter support center axis O2 of the breaking cutter support 102 (support body 107), the breaking cutter wheel 103 has a caster effect. Therefore, the first and second breaking fixtures 94a, 94b (breaking fixtures) only need to run (move) in a circular shape from the vicinity of the starting point of the end tangent line K2 and draw a circular trajectory (the breaking fixtures only need to move in a circular shape). The breaking cutter wheel 103 runs (moves) slightly in a specified direction from the vicinity of the starting point of the end tangent K2, and rotates in the direction around (around the axis) the center axis O2 of the cutter bracket. The rolling (rotation) direction of the peripheral edge 112 of the breaking cutter wheel 103 is toward the running (moving) direction of the first and second breaking clamps 94a, 94b (breaking cutter bracket 102) (the extension direction of the virtual end tangent), and the rolling direction of the peripheral edge 112 of the breaking cutter wheel 103 can be quickly and easily changed.

[0258] In the breaking system 10a and the grinding processing method (glass plate processing system 10), in each end tangent forming area of ​​the edge 66b of the glass plates 11a and 11b to be processed, the rolling direction of the peripheral edge 112 of the breaking cutting wheel 103 can be made consistent with the running direction of the first and second breaking fixtures 94a and 94b (breaking fixtures) (the extension direction of the virtual end tangents of the edge 66b of the glass plates 11a and 11b), and the end tangents K2 are placed in these end tangent forming areas, so that multiple end tangents K2 can be efficiently formed in the end tangent forming areas of the edge 66b of the glass plates 11a and 11b in a short time.
