Description

Technical Field

[0001] This invention relates to the field of glass edging technology, and particularly to a glass edging machine and a method for grinding the corners of glass. Background Technology

[0002] When processing rectangular glass, double-sided glass edging machines typically require precision grinding of the glass's edges and rounding (R-corners) or chamfering (C-corners) of the four sharp corners. R-corners or C-corners are formed by using a high-speed rotating grinding wheel to perform circular or linear interpolation motions in the glass corner area. This allows the grinding wheel to precisely cut the sharp corners along a preset trajectory, resulting in smooth rounded corners or regular chamfers.

[0003] To ensure the accuracy of the chamfering process, the CNC system must acquire the glass's position information on the conveyor belt in real time and precisely control the timing of the grinding wheel's advance and retraction based on this position signal. The accuracy of the position signal directly affects the chamfering position, size, and final chamfering shape quality.

[0004] Traditional equipment often uses limit switches to detect the glass position. However, limit switches have low detection accuracy and cannot meet the high precision requirements of timing control in R-corner / C-corner machining. Furthermore, limit switches are mechanical structures that rely on springs and contacts to complete their operation; after prolonged use, the springs are prone to fatigue, and the contacts are prone to burning or damage, leading to unstable detection signals or even complete failure, further affecting the reliability and consistency of chamfering.

[0005] Therefore, in practical applications, there is an urgent need for a detection method that can replace limit switches and achieve higher position detection accuracy and reliability to ensure the stability and accuracy of glass rounding or beveling processing. Summary of the Invention

[0006] Firstly, the purpose of this invention is to provide a glass edging machine to solve the problem of low glass edging accuracy.

[0007] Secondly, the purpose of this invention is to provide a method for grinding the corners of glass to solve the problem of low precision in glass corner grinding.

[0008] To solve the above problems, the present invention provides a glass edging machine, including a machine body, a conveying device and a chamfering device on both sides of the machine body, a glass length detection device at the end of the conveying device, a glass position detection device on one side of the chamfering device, and the conveying device, the glass length detection device, the glass position detection device and the chamfering device are all connected to a CNC system; The conveying device is used to convey the glass to be edged, the glass length detection device is used to detect the preset length of the glass along the first direction, the glass position detection device is used to touch the opposite edge of the glass along the second direction and detect the position point data of the opposite edge of the glass, and the chamfering device performs an edge grinding operation on the corner of the glass according to the position point data.

[0009] In some embodiments, the glass position detection device includes a servo motor, a rotating shaft, and a contact block. The servo motor is mounted on the main body of the device, and the contact block is connected to the servo motor via the rotating shaft.

[0010] In some embodiments, the contact block includes an abutting portion and a mounting portion, the abutting portion being used to contact the glass, the mounting portion being connected to the rotating shaft, and a connecting portion being provided between the abutting portion and the mounting portion.

[0011] In some embodiments, the abutment portion includes one or more arcuate protrusions; and / or The side of the connecting part is provided with an arc-shaped groove; and / or The mounting part is provided with a through hole for connecting with the coupling.

[0012] In some embodiments, the material of the contact block is selected from one or more of polyethylene, polyoxymethylene, nylon, or polycarbonate.

[0013] In some embodiments, the glass length detection device includes a limit switch, a swing arm, and a roller. The limit switch is disposed on the main body of the device, and the roller is connected to the limit switch via the swing arm.

[0014] In some embodiments, the conveying device includes a lower synchronous belt and an upper synchronous belt, both of which are disposed on one side of the machine body, with the upper synchronous belt disposed above the lower synchronous belt.

[0015] In some embodiments, the chamfering device includes a drive unit and a grinding wheel, the drive unit being mounted on the machine body and the grinding wheel being connected to the drive unit.

[0016] To solve the above-mentioned technical problems, the present invention also provides a method for grinding the corner of glass, using the aforementioned glass edging machine, the method comprising: The glass length is obtained along the first direction based on the glass length detection device. The glass position detection device touches the opposite edge of the glass along the second direction and obtains the position value of the opposite edge of the glass along the second direction. The chamfering device performs a chamfering operation on the corners of the glass based on the value of the location point.

[0017] In some embodiments, the glass position detection device includes a servo motor, a rotating shaft, and a contact block. The servo motor is mounted on the main body of the device, and the contact block is connected to the servo motor via the rotating shaft.

[0018] In some embodiments, the method includes: The servo motor drives the contact block to rotate to the starting position; The conveying device conveys glass to move along the first direction.

[0022] The following detailed description, in conjunction with the accompanying drawings, will further illustrate the present invention. Detailed Implementation

[0023] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. Several embodiments of the invention are illustrated in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0024] It should be noted that when a component is said to be "fixed to" another component, it can be directly on the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The present invention provides a glass edging machine, including a machine body, a conveying device 4 and a chamfering device 5 on both sides of the machine body, a glass length detection device 2 at the end of the conveying device 4, and a glass position detection device 3 on one side of the chamfering device 5. The conveying device 4, the glass length detection device 2, the glass position detection device 3 and the chamfering device 5 are all connected to a CNC system. The conveying device 4 is used to convey the glass 1 to be edged, the glass length detection device 2 is used to detect the preset length of the glass 1 along the first direction, the glass position detection device 3 is used to touch the opposite edge of the glass 1 along the second direction and detect the position point data of the opposite edge of the glass 1, and the chamfering device 5 performs corner grinding operation on the corner of the glass 1 according to the position point data.

[0027] The glass edging machine provided by this invention detects the length of glass 1 through a glass length detection device 2 and touches two opposing edges of glass 1 through a glass position detection device 3 to detect the position point values ​​of the two opposing edges of glass 1. This allows for accurate determination of the position of glass 1 on the conveying device 4. Furthermore, by touching the two opposing edges of glass 1 through the glass position detection device 3, scratches and other damage to glass 1 are effectively avoided. Consequently, the chamfering device 5 performs an angle grinding operation on glass 1 based on the position point values, resulting in more precise rounded or beveled corners.

[0028] In some embodiments, the first direction is the conveying direction of the glass 1 to be edged, and the second direction is perpendicular to the first direction.

[0029] In some embodiments, the glass 1 to be edged is rectangular, the first direction is the length direction of the glass 1, and the second direction is the width direction of the glass 1; or, the first direction is the width direction of the glass 1, and the second direction is the length direction of the glass 1.

[0030] In some embodiments, the glass position detection device 3 includes a servo motor 31, a rotating shaft 32, and a contact block 33. The servo motor 31 is mounted on the main body 10, and the contact block 33 is connected to the servo motor 31 through the rotating shaft 32.

[0031] It should be noted that in the existing technology, the glass edging machine often uses rollers to convey the glass 1. Due to the gap between the rollers, roller wear and aging, bearings are prone to rust and jamming, or the conveying speed is not synchronized, etc., the processing is unstable, resulting in uneven grinding marks, edge chipping, surface ripples, indentations and scratches, which affect the appearance and strength of the product.

[0032] The glass position detection device 3 of the present invention replaces the roller with a contact block 33 of a specific structure, which can avoid poor detection accuracy caused by roller gaps, bearing rust and jamming, and roller wear. However, using the contact block 33 instead of the roller also has the following problems: when the glass position detection device 3 uses a roller, after detecting the front end of the glass 1, the roller will rotate at a certain angle and roll with the edge of the glass 1 to wait for the tail end to arrive, resulting in a long contact time with the glass 1. If the contact block 33 does the same, it will be prone to wear. Therefore, after detecting the front end of the glass 1, the contact block 33 will rotate at a certain angle and wait for the tail end to arrive without contacting the edge of the glass 1. Because the present invention adds a glass length detection device 2, which can detect the length of the glass 1, the contact block 33 is rotated to the corresponding position when the tail end of the glass 1 is about to arrive. In this way, the contact block 33 only contacts the glass 1 during the detection process, effectively reducing the wear of the contact block 33.

[0033] Furthermore, the specific structure of the contact block 33 is as follows: in some embodiments, the contact block 33 includes an abutting part 340 and a mounting part 341. The abutting part 340 is used to contact the glass 1, the mounting part 341 is connected to the rotating shaft 32, and a connecting part 343 is provided between the abutting part 340 and the mounting part 341.

[0034] In some embodiments, the abutment portion 340 includes one or more arcuate protrusions 34; and / or the side of the connecting portion 343 is provided with an arcuate groove 35; and / or the mounting portion 341 is provided with a through hole 342 for connecting with the rotating shaft 32.

[0035] The contact portion 340 of the contact block 33 is provided with one or more arc-shaped protrusions 34, which can reduce the probability of the glass 1 and the contact block 33 jamming together. Preferably, the contact portion 340 includes two arc-shaped protrusions 34. More preferably, the contact portion 340 includes one arc-shaped protrusion 34. In actual production, when the contact portion 340 includes one arc-shaped protrusion 34, it can greatly reduce the possibility of the glass 1 jamming or being forced together.

[0036] In some implementations, the rotation of the contact block 33 is directly connected to the rotation shaft of the high-precision absolute value servo motor 31. The rotation position or angle is controlled by the servo system, and a zero-point absolute value is set, which is accurate and effective over a long period. Even if zero-point loss occurs, the zero-point position can be quickly determined through normal operation, and the system can return to normal operation after parameter correction and first-piece inspection.

[0037] In some embodiments, the material of the contact block 33 is selected from one or more of polyethylene, polyoxymethylene, nylon, or polycarbonate. Preferably, the material of the contact block 33 is high-density polyethylene, which has an extremely low coefficient of friction with glass 1, good rigidity and suitable hardness, and slides smoothly on the surface of glass 1 without damaging glass 1.

[0038] In some embodiments, the glass length detection device 2 includes a limit switch 21, a swing arm 22, and a roller 23. The limit switch 21 is disposed on the main body 10, and the roller 23 is connected to the limit switch 21 through the swing arm 22.

[0039] In some embodiments, the conveying device 4 includes a lower synchronous belt 41 and an upper synchronous belt 42, both of which are disposed on one side of the machine body 10, with the upper synchronous belt 41 disposed above the lower synchronous belt 42.

[0040] In some embodiments, the chamfering device 5 includes a drive unit 52 and a grinding wheel 51, the drive unit 52 being mounted on the machine body 10, and the grinding wheel 51 being connected to the drive unit.

[0041] To solve the above-mentioned technical problems, the present invention also provides a method for grinding the corner of glass 1, using the glass 1 edge grinding machine described above, the method comprising: The glass length detection device 2 is used to obtain the preset length of glass 1 along the first direction; The glass position detection device 3 touches the opposite edge of the glass 1 along the second direction and obtains the position value of the opposite edge of the glass 1 along the second direction. The chamfering device 5 performs a chamfering operation on the corner of the glass 1 according to the value of the position point.

[0042] The grinding method for the corners of glass 1 provided by this invention is used in the glass 1 edging machine. By detecting the length of glass 1 and touching two opposite edges of glass 1 to obtain position point values, the position of glass 1 on the conveying device 4 is accurately determined, enabling the chamfering device 5 to perform high-precision grinding of the corners. This method not only improves the positioning accuracy and processing consistency of chamfering R-angles or C-angles and effectively avoids scratches on the surface of glass 1, but also improves the reliability and applicability of the system, enabling it to adapt to the automated processing of glass 1 of different specifications, and significantly improving the quality of finished products and the stability of equipment operation.

[0043] In some embodiments, the glass position detection device 3 includes a servo motor 31, a rotating shaft 32, and a contact block 33. The servo motor 31 is mounted on the main body 10, and the contact block 33 is connected to the servo motor 31 through the rotating shaft 32.

[0044] In some embodiments, the method includes: The servo motor drives the contact block 33 to rotate to the starting position; The conveying device 4 conveys the glass 1 to move along the first direction. When the front edge 101 of the glass 1 along the second direction contacts the contact block 33, the contact block 33 swings to the first angle position, and the CNC device records the position value of the front edge 101 of the glass 1. The servo motor drives the collision block 33 to rotate to the avoidance angle position, so that the collision block 33 remains separated from the side of the glass 1; When the glass 1 moves a distance along the first direction to reach the preset length, the servo motor drives the contact block 33 to rotate and contact the rear edge 103 of the glass 1 along the second direction, and continues to swing to the second angle position. The CNC system records the position value of the rear edge 103 of the glass 1. The servo motor drives the contact block 33 to leave the glass 1 and return to the starting position; The chamfering device 5 is used to grind the corners of the glass 1 according to the position values ​​of the front edge 101 and the rear edge 103 of the glass 1.

[0045] It is understood that the front edge 101 and the rear edge 103 of the glass 1 are the opposite edges of the glass 1 along the second direction.

[0046] Example 1 Please see Figures 1 to 8 The figure shows a glass edging machine according to the first embodiment of the present invention, including a machine body 10, a conveying device 4, a glass length detection device 2, a glass position detection device 3, a chamfering device 5, and a CNC system (not shown in the figure).

[0047] The conveying device 4, the glass length detection device 2, the glass position detection device 3, and the chamfering device 5 are each provided in two sets. The two conveying devices 4 and the two glass length detection devices 2 are symmetrically arranged on both sides of the machine body 10. The glass length detection device 2 is located at the end of the conveying device 4. The two glass position detection devices 3 are symmetrically arranged on both sides of the machine body 10. The two chamfering devices 5 are arranged on both sides of the machine body and on one side of the glass position detection device 3. The CNC system is connected to the conveying device 4, the glass length detection device 2, the glass position detection device 3, and the chamfering device 5. The conveying device 4 is used to convey the glass 1 to be edged. The glass length detection device 2 is used to detect the length of the glass 1. The glass position detection device 3 is used to touch the two opposite edges of the glass 1 and detect the position point data of the two opposite edges of the glass 1. The chamfering device 5 is used to perform chamfering or beveling operations on the four corners of the glass 1 according to the position point data.

[0048] Understandably, the conveying device 4 transports the glass 1 to the position of the glass position detection device 3. During this process, when the glass 1 is just transported by the conveying device 4, the glass length detection device 2 detects the length of the glass 1. Then, it touches the front 101 and the rear 103 of the glass 1 at the glass position detection device 3 to obtain the position values ​​of the front 101 and the rear 103 of the glass 1. The chamfering device 5 performs rounding or beveling operations on the four sharp corners of the glass 1 based on the position values ​​of the front 101 and the rear 103.

[0049] It is worth noting that in this embodiment, the two opposite sides along the second direction are the front side 101 and the back side 103, and the two opposite sides along the first direction are the left side 102 and the right side 104.

[0050] Specifically, in this embodiment, both conveying devices 4 include a lower synchronous belt 41 and an upper synchronous belt 42. The lower synchronous belt 41 and the upper synchronous belt 42 are both disposed on one side of the machine body 10, and the upper synchronous belt 42 is disposed above the lower synchronous belt 41.

[0051] It should be noted that both the upper synchronous belt 42 and the lower synchronous belt 41 are precisely driven by motors to ensure that the upper synchronous belt 42 and the lower synchronous belt 41 run synchronously and form a glass 1 clamping surface between the upper synchronous belt 42 and the lower synchronous belt 41. The glass 1 extends a certain distance from the lower synchronous belt 41 and the upper synchronous belt 42 and is clamped, and is continuously conveyed in the conveying direction A at a constant or variable speed. The glass 1 does not stop during operation.

[0052] Specifically, in this embodiment, the two chamfering devices 5 include a drive unit 52 and a grinding wheel 51. The drive unit 52 is mounted on the machine body 10, and the grinding wheel is connected to the output end of the drive unit 52.

[0053] It should be noted that the drive unit 52 drives the grinding wheel 51 to perform rounding or beveling operations on the four corners of the glass 1.

[0054] Specifically, in this embodiment, the two glass length detection devices 2 include a limit switch 21, a swing arm 22, and a roller 23. The limit switch 21 is disposed on the main body 10 and located on one side of the conveying device 4. The roller 23 is connected to the limit switch 21 through the swing arm 22.

[0055] It should be noted that when glass 1 moves along the first direction, the front edge 101 of glass 1 contacts the roller 23 on the limit switch 21. The limit switch 21 actuates, generating a rising edge signal, which is input to the CNC system. When the rear edge 103 of glass 1 leaves the roller 23, the limit switch 21 resets, generating a falling edge signal, which is also input to the CNC system. The CNC system of the equipment obtains the preset length L of glass 1 by synchronously measuring the position of the belt conveyor servo motor 31 between the rising edge signal and the falling edge signal. It should be noted that the preset length L can be a fuzzy length of glass 1.

[0056] Specifically, in this embodiment, the two glass position detection devices 3 include a servo motor 31, a rotating shaft 32, and a contact block 33. The servo motor 31 is mounted on the main body 10 via a bracket, and the contact block 33 is connected to the output end of the servo motor 31 via the rotating shaft 32.

[0057] It should be noted that one end of the rotating shaft 32 is connected to the motor shaft of the servo motor 31, and the other end is connected to the contact block 33. The rotation of the servo motor 31 can drive the contact block 33 to rotate. In the low torque mode of the servo motor 31, the rotation of the contact block 33 can also drive the servo motor 31 to rotate.

[0058] Furthermore, the contact block 33 includes an abutting portion 340 and a mounting portion 341. The abutting portion 340 is used to contact the glass, and the mounting portion 341 is connected to the rotating shaft. A connecting portion 343 is provided between the abutting portion 340 and the mounting portion 341. The abutting portion 340 includes one or more arc-shaped protrusions, and the mounting portion 341 has a through hole 342 for connecting to the connecting shaft 32. In this embodiment, arc-shaped protrusions 34 are symmetrically provided on both sides of one end of the contact block 33. The contact block 33 is made of high-density PE, the distance between the center points of the two arc-shaped protrusions 34 is 60 mm, and the radius of the two protrusions is 13 mm. It is understood that the size of the contact block is not limited to the above-listed dimensions. In other optional embodiments, the material of the contact block is selected from one or more of polyethylene, polyoxymethylene, nylon, or polycarbonate.

[0059] It is worth noting that when performing the corner grinding operation on glass 1, the glass corner grinding method uses the aforementioned glass edging machine, and the method includes the following steps: S1, based on the glass length detection device 2, obtain the preset length of the glass along the first direction; S2, the glass position detection device 3 touches the two opposing edges of the glass 1 along the second direction and obtains the position point values ​​of the two opposing edges of the glass 1 along the second direction. S3, based on the position point values ​​of the two opposing sides, the chamfering device 5 performs rounding or beveling operations on the four sharp corners of the glass; In some implementations, steps S2 and S3 include the following steps: The servo motor drives the contact block to rotate to the starting position; The conveying device conveys glass along the first direction. When the front edge of the glass contacts the contact block, the contact block swings to a first angle position, and the CNC device records the value of the front position point of the glass. The servo motor drives the collision block to rotate to the avoidance angle position, so that the collision block remains separated from the side of the glass; When the glass moves a distance in the first direction to the preset length, the servo motor drives the contact block to rotate and contact the rear of the glass, and continues to swing to the second angle position. The CNC system records the value of the rear position point of the glass. The servo motor drives the contact block to leave the glass and return to the starting position; The chamfering device is used to chamfer or bevel the four corners of the glass according to the front and rear position point values.

[0060] Preferably, steps S2 and S3 include the following steps: The servo motor 31 causes the rotating shaft 32 to rotate, so that the center line a of the contact block 33 forms an angle α1 with the Y axis, which forms the starting position of the contact block 33. When glass 1 is conveyed along the first direction, when the front edge 101 contacts the contact block 33, the rotating shaft 32 swings relative to the starting position by a certain angle, so that the center line a of the contact block 33 forms an angle β1 with the Y axis. At this time, the CNC system of the equipment obtains the position value of the front edge 101 of glass 1 through the synchronous belt conveying servo motor 31. After the servo motor 31 drives the rotating shaft 32 to rotate in the direction of B by a certain angle, the center line a of the contact block 33 forms an angle γ1 with the X-axis. The contact block 33 does not contact the edge of the glass 1 and waits to detect the back edge 103 of the glass 1. From the moment the position value of the front edge 101 of glass 1 is obtained, when the conveying distance of glass 1 on the synchronous belt approaches the preset length L, the servo motor 31 is started, causing the rotating shaft 32 to rotate in the direction B by a certain angle. Then, the contact block 33 contacts the rear edge 103 of glass 1. The rotating shaft 32 continues to rotate, causing the contact block 33 to press against the rear edge 103 of glass 1 and continue rotating in the direction B. After the contact block 33 has rotated by a certain angle, the center line a of the contact block 33 forms an angle δ1 with the Y-axis. At this time, the CNC system of the equipment obtains the position value of the rear edge 103 of glass 1 through the synchronous belt conveyor servo motor 31.

[0061] Then, the servo motor 31 reduces its speed, causing the contact block 33 to disengage from the back 103 of the glass 1.

[0062] Next, the servo motor 31 causes the rotating shaft 32 to rotate in the direction of B or in the opposite direction of B, so that the contact block 33 is reset to the starting position.

[0063] The CNC system of the equipment controls the grinding wheel 51 on the chamfering device 5 to move sequentially based on the obtained position signals of the front 101 and rear 103 of the glass 1, and performs rounding (R-corner) or beveling (C-corner) operations on the four sharp corners of the glass 1.

[0064] Example 2 Please see Figures 9 to 13 The image shows a glass edging machine according to the second embodiment of the present invention, which differs from the glass edging machine in the first embodiment in that: Specifically, in this embodiment, the side of the connecting portion is provided with an arc-shaped groove 35, and the contact block 33 is provided with a protrusion, which is made of high-density PE. The closest edge of the two grooves is 21.9 mm, and the radius of the groove is 66 mm. It is understood that the size of the contact block is not limited to the above-listed dimensions. In other optional embodiments, the material of the contact block is selected from one or more of polyethylene, polyoxymethylene, nylon, or polycarbonate.

[0065] It is worth noting that when performing the corner grinding operation on glass 1, the glass corner grinding method uses the aforementioned glass edging machine, and the method includes the following steps: S1, based on the glass length detection device 2, obtain the preset length of the glass along the first direction; S2, the glass position detection device 3 touches the two opposing edges of the glass 1 along the second direction and obtains the position point values ​​of the two opposing edges of the glass 1 along the second direction. S3, based on the position point values ​​of the two opposing sides, the chamfering device 5 performs rounding or beveling operations on the four sharp corners of the glass; In some implementations, steps S2 and S3 include the following steps: The servo motor drives the contact block to rotate to the starting position; The conveying device conveys glass along the first direction. When the front edge of the glass contacts the contact block, the contact block swings to a first angle position, and the CNC device records the value of the front position point of the glass. The servo motor drives the collision block to rotate to the avoidance angle position, so that the collision block remains separated from the side of the glass; When the glass moves a distance in the first direction to the preset length, the servo motor drives the contact block to rotate and contact the rear of the glass, and continues to swing to the second angle position. The CNC system records the value of the rear position point of the glass. The servo motor drives the contact block to leave the glass and return to the starting position; The chamfering device is used to chamfer or bevel the four corners of the glass according to the front and rear position point values.

[0066] Preferably, steps S2 and S3 include the following steps: The servo motor 31 causes the rotating shaft 32 to rotate, so that the center line a of the contact block 33 forms an angle α2 with the Y axis, which forms the starting position of the contact block 33. When glass 1 is conveyed along the first direction, when the front edge 101 contacts the contact block 33, the rotating shaft 32 swings relative to the starting position by a certain angle, so that the center line a of the contact block 33 forms an angle β2 with the Y axis. At this time, the CNC system of the equipment obtains the position value of the front edge 101 of glass 1 through the synchronous belt conveying servo motor 31. After the servo motor 31 drives the rotating shaft 32 to rotate in the direction of B by a certain angle, the center line a of the contact block 33 forms an angle γ2 with the X-axis. The contact block 33 does not contact the edge of the glass 1 and waits to detect the back edge 103 of the glass 1. From the moment the position value of the front edge 101 of glass 1 is obtained, when the conveying distance of glass 1 on the synchronous belt approaches the preset length L, the servo motor 31 is started, causing the rotating shaft 32 to rotate in the direction B by a certain angle. Then, the contact block 33 contacts the rear edge 103 of glass 1. The rotating shaft 32 continues to rotate, causing the contact block 33 to press against the rear edge 103 of glass 1 and continue rotating in the direction B. After the contact block 33 has rotated by a certain angle, the center line a of the contact block 33 forms an angle δ2 with the Y-axis. At this time, the CNC system of the equipment obtains the position value of the rear edge 103 of glass 1 through the synchronous belt conveyor servo motor 31.

[0067] Then, the servo motor 31 reduces its speed, causing the contact block 33 to disengage from the back 103 of the glass 1.

[0068] Next, the servo motor 31 causes the rotating shaft 32 to rotate in the direction of B or in the opposite direction of B, so that the contact block 33 is reset to the starting position.

[0069] The CNC system of the equipment controls the grinding wheel 51 on the chamfering device 5 to move sequentially based on the obtained position signals of the front 101 and rear 103 of the glass 1, and performs rounding (R-corner) or beveling (C-corner) operations on the four sharp corners of the glass 1.
