[0026] Embodiment: A product thickness bin automatic blanking machine includes a frame, a glass material taking and handling mechanism 1, a glass positioning and conveying mechanism 2, an empty tray bin 3, a blanking bin 4, an empty tray handling mechanism 5, a glass discharging and handling mechanism 6 and a control system. The at least one empty tray bin 3 and the at least one blanking bin 4 are respectively fixedly installed on the frame. Empty trays can be stacked in the empty tray bin 3 with horizontal direction stopping, and full trays can be stacked in the blanking bin 4 with horizontal direction stopping. The glass material taking and handling mechanism 1 can transport the glass product 7 detected by the glass thickness detector 19 to the corresponding glass positioning and conveying mechanism 2. The glass positioning and conveying mechanism 2 can position and convey forward the glass product 7. The empty tray handling mechanism 5 can transport the empty trays in the empty tray bin to the blanking bin 4. The glass discharging and handling mechanism 6 can transport the glass product 7 at the end of the glass positioning and conveying mechanism 2 to the empty trays in the corresponding blanking bin 4 for storage. The control system is electrically connected and communicates with the glass thickness detector 19. The control system controls the glass material taking and handling mechanism 1 to place glass products 7 with different thicknesses on different glass positioning and conveying mechanisms 2 for conveying according to the detection data of the glass thickness detector 19.

[0027] The glass product 7 is subjected to thickness detection on the glass thickness detector 19. It can be detected one piece at a time or multiple pieces can be detected synchronously. A better solution is to detect four glass products 7 at four positions on the glass thickness detector 19 simultaneously. After the detection of the glass product 7 is completed, the glass product 7 is placed one by one on the glass positioning and conveying mechanism 2 by the glass material taking and handling mechanism 1 according to the detection data of the glass thickness detector 19 for conveying. After the glass products 7 are placed on different glass positioning and conveying mechanisms 2 according to different thickness specifications, the glass products 7 of the same thickness specification are located on the same glass positioning and conveying mechanism 2. When the glass product 7 is conveyed to the end position, the glass discharging and handling mechanism 6 places the glass products 7 on each glass positioning and conveying mechanism 2 into the top trays of different discharging bins 4 for material collection. When the top trays of the discharging bin 4 are filled with glass products 7, the empty tray handling mechanism 5 transports an empty tray from the empty tray bin 3 and places it on the top of the discharging bin 4, thus realizing the full-automatic bin-dividing and discharging operation of the glass product 7 in a cycle. The whole process does not require manual operation, saving labor, and the glass products 7 are accurately classified, avoiding the situation of material mixing. At the same time, without manual operation, it avoids the pollution and damage of the glass products 7. As an optimal solution, a feeding induction device can also be set on the frame to sense whether there is a glass product 7 at a specified position at the end of the glass positioning and conveying mechanism 2 or whether the glass discharging and handling mechanism 6 is carrying a glass product 7, so as to avoid the situation that the glass discharging and handling mechanism 6 fails to carry or there is no material, resulting in cavities on the trays in the discharging bin 4. A detection device can also be set above the discharging bin 4 to detect whether there is a glass product 7 in each cavity of the top tray of the discharging bin 4. The above induction device and detection device can be cameras, which are realized by means of photographing and comparison.

[0028] The glass material taking and handling mechanism 1 includes a three-dimensional space motion mechanism and a first suction cup 8. The first suction cup 8 is installed on the moving end of the three-dimensional space motion mechanism. The three-dimensional space motion mechanism can drive the first suction cup 8 to operate within a set range of three-dimensional space. The first suction cup 8 can negatively pressure adsorb the glass product 7. The control system controls the operation of the three-dimensional space motion mechanism and the negative pressure start and stop of the first suction cup 8. Let the Z direction be the vertical direction, and the X direction and Y direction be two mutually perpendicular directions on the horizontal plane. The three-dimensional space motion mechanism can include a first X-direction track 9, a first Y-direction track 10, a first X-direction slider 11, a first Y-direction slider 12, a first Z-direction slider 13, a first X-direction driving device 14, a first Y-direction driving device 15, and a first Z-direction driving device 16. The first X-direction track is fixedly installed on the machine frame. The first X-direction slider is installed on the first X-direction track so as to be able to slide along the X direction. The first Y-direction track is fixedly installed on the first X-direction slider. The first Y-direction slider is installed on the first Y-direction track so as to be able to slide along the Y direction. The first Z-direction slider is installed on the first Y-direction slider so as to be able to slide longitudinally. The first X-direction driving device, the first Y-direction driving device, and the first Z-direction driving device respectively drive the first X-direction slider, the first Y-direction slider, and the first Z-direction slider to move. Among them, the first X-direction driving device, the first Y-direction driving device, and the first Z-direction driving device can be cylinders or can be a motor driving a lead screw nut mechanism. The first suction cup 8 moves within a three-dimensional space by the movement of the slider in three mutually perpendicular directions. In addition to this structure, it can also be a multi-joint manipulator, or a horizontal rotating arm cooperating with a longitudinal slider, etc., to enable the first suction cup 8 to move to any position within a certain range of three-dimensional space and place the glass product 7 on the corresponding glass positioning and conveying mechanism 2. It is best to install a traceless suction cup sleeve on the suction cup to avoid leaving marks on the surface of the glass product 7.

[0029] Let the X direction and the Y direction be two mutually perpendicular directions on the horizontal plane. The glass material taking and handling mechanism 1 further includes a suction cup variable distance adjusting mechanism. The suction cup variable distance adjusting mechanism includes an X-direction moving member 17 and a Y-direction moving member 18. The X-direction moving member 17 is installed on the moving end of the three-dimensional space motion mechanism so as to be able to telescopically move along the X direction. The Y-direction moving member 18 is installed on the moving end of the X-direction moving member 17 so as to be able to telescopically move along the Y direction. At least two suction cups are respectively fixedly installed at both ends of the Y-direction moving member 18 along the telescopic movement direction. Through the above variable distance adjusting device, the positions of multiple first suction cups 8 on the glass material taking and handling mechanism 1 can be adjusted so that each first suction cup 8 is exactly opposite to the position of each glass product 7 on the glass thickness detector for negative pressure adsorption, avoiding material taking failure. Among them, the X-direction moving member 17 and the Y-direction moving member 18 can be slide table cylinders or can be a motor driving a lead screw nut mechanism, etc.

[0030] The glass positioning and conveying mechanism 2 is a belt 21 conveying mechanism made of polyurethane material. On both sides of the belt 21 in the width direction of the belt 21, there are limit baffles 22 respectively. On the belt 21 of the belt 21 conveying mechanism, there are a number of longitudinal blocks 23 arranged at intervals. A groove-shaped space for placing only one glass product 7 is just formed between the limit baffles 22 on both sides of the belt 21 and the longitudinal blocks 23 arranged at intervals on the belt 21. The surface of the belt 21 made of polyurethane material is smooth and will not damage the glass product 7 or cause scratches on the surface of the glass product 7 due to water distribution during the conveying process. The longitudinal blocks 23 arranged at intervals on the belt 21 realize the zoning of the belt 21 along the conveying direction. Cooperating with the limit baffles 22 on both sides of the belt 21, it realizes the positioning of the glass product 7 in the four directions of front, back, left and right, avoiding the change of the position of the glass product 7 during the conveying process, which is beneficial to accurately placing the glass product 7 into each acupoint of the tray during blanking. Of course, in addition to using the belt 21 conveying mechanism, it can also be conveyed forward by pushing, or there is no conveying, and only different material boxes are set to classify and temporarily store glass products 7 with different thickness specifications.

[0031] Both the empty tray bin 3 and the blanking bin 4 include a tray bottom support, a bottom support lifting drive device 24 and a tray fence 25. The tray fence 25 is fixedly installed on the tray bottom support. A space for stacking and positioning the trays is formed between the tray bottom support and the tray fence 25. The tray bottom support is longitudinally liftably installed on the frame, and the bottom support lifting drive device 24 drives the tray bottom support to lift. Every time an empty tray is taken away from the empty tray bin 3, its bottom support rises by the thickness of one tray. Every time an empty tray is placed in the blanking bin 4, its bottom support drops by the thickness of one tray, so that the empty tray handling mechanism 5 and the glass blanking handling mechanism 6 always take and place materials at a fixed height position, avoiding problems such as interference, collision and drop damage. The tray fence 25 and the tray bottom support work together to limit the stacked trays.

[0032] The tray bottom support includes a lower layer bottom support 26, a telescopic slide rail 27 and an upper layer bottom support 28. The fixed end of the telescopic slide rail 27 is fixedly installed on the lower layer bottom support 26, and the upper layer bottom support 28 is fixedly installed on the movable end of the telescopic slide rail 27. The tray fence 25 is fixedly installed on the upper side bottom support to form a drawer structure. The above structure makes both the empty tray bin 3 and the blanking bin 4 form a drawer structure. By means of pulling, the bin is displaced in the horizontal direction, which is convenient for loading empty trays and unloading full trays, avoiding interference with other mechanisms of the equipment and also avoiding harm to the workers for loading and unloading materials during the operation of the equipment.

[0033] The empty tray bin 3 and the blanking bin 4 are respectively provided with tray sensors 29. The tray sensors 29 can sense the trays at the upper limit positions in the empty tray bin 3 and the blanking bin 4 and transmit signals to the control system. An alarm device 30 is also provided. The control system controls the alarm device 30 to issue a material shortage alarm or a full material alarm according to the signals of the tray sensors 29 in the empty tray bin 3 and the blanking bin 4. The above mechanism realizes the automatic detection and alarm of material shortage in the empty tray bin 3 and full material in the blanking bin 4, facilitating workers to timely understand the tray conditions in the empty tray bin 3 and the blanking bin 4 and load and unload materials in a timely manner.

[0034] The empty tray bin 3 is also provided with a tray positioning and separating mechanism. The tray positioning and separating mechanism includes a separating tray support 31, an L-shaped insert 32 and an insert driving device 33. The separating tray support 31 is fixedly installed on the frame, and at least two separating tray supports 31 are respectively located on two opposite sides of the empty tray bin 3. The L-shaped insert 32 is installed on the separating tray support 31 so as to be able to move forward in the direction of the tray. The horizontal side wall of the L-shaped insert 32 can just be inserted into the gap between the top empty tray and the adjacent empty tray. The longitudinal side wall of the L-shaped insert 32 can stop against the side wall of the empty tray. The insert driving device 33 drives the L-shaped insert 32 to move back and forth, and the control system controls the start and stop of the insert driving device 33. The tray positioning and separating mechanism separates the topmost tray in the empty tray bin 3 from the second-layer tray adjacent thereto, avoiding carrying two empty trays at a time. At the same time, the L-shaped insert 32 also slaps and positions the topmost empty tray left and right to ensure accurate handling.

[0035] The empty tray bin 3 and the blanking bin 4 are arranged at intervals along the Y direction. The empty tray handling mechanism 5 includes a first planar motion mechanism capable of moving along the longitudinal direction and the Y direction, a chuck support 34, a tray chuck 35, and a clamping drive device 36. The chuck support 34 is fixedly installed on the moving end of the first planar motion mechanism. The first planar motion mechanism can drive the chuck support 34 to move on the two-dimensional plane formed by the longitudinal direction and the X direction. The paired tray chucks 35 can be opened and clamped relative to each other along the width direction of the tray to clamp the two opposite side walls of the tray. The clamping drive device 36 drives the tray chucks 35 to perform clamping or loosening movements. The control system controls the movement of the moving end of the first planar motion mechanism and the start and stop of the clamping drive device 36. By the movement of the first planar motion mechanism in the longitudinal direction and the Y direction, the empty trays in the empty tray bin 3 are transported into the blanking bin 4. The tray handling is achieved by clamping with the jaw mechanism. For the solution of synchronously collecting materials into four bins for the glass products 7, it is optimal to arrange two blanking bins 4 and one empty tray bin 3 on each side of the glass positioning and conveying mechanism 2, and collect materials in two directions respectively. The material collection speed is fast, which is beneficial to improving the efficiency of collecting materials into bins for the glass products 7. Among them, the first planar motion mechanism includes a second Y-direction track 37, a second Y-direction slider 38, a second Z-direction slider 39, a first Y-direction drive device 40, and a second Z-direction drive device 41. The second Y-direction track is fixedly installed on the frame. The second Y-direction slider is installed on the second Y-direction track so as to be able to slide along the X direction. The second Z-direction slider is installed on the second Y-direction slider so as to be able to slide along the longitudinal direction. The second Y-direction drive device and the second Z-direction drive device drive the second X-direction slider and the second Z-direction slider to move respectively. Among them, the second Y-direction drive device and the second Z-direction drive device can be cylinders or a motor driving a lead screw-nut mechanism. The movement of the tray chuck 35 on the two-dimensional plane is realized by the movement of the slider in two mutually perpendicular directions. In addition to this structure, it can also be a multi-joint manipulator or a horizontal rotating arm mechanism, etc., to realize the tray chuck 35 transporting the trays in the empty tray bin 3 into the blanking bin 4.

[0036] The blanking bin 4 is located on one or both sides of the conveying end of the glass positioning and conveying mechanism 2 along the X direction. The glass blanking and handling mechanism 6 includes a second planar motion mechanism capable of moving along the longitudinal direction and the X direction, and a second suction cup 42. The second suction cup 42 is fixedly installed on the moving end of the second planar motion mechanism. The second planar motion mechanism can drive the suction cup to move on the two-dimensional plane formed by the longitudinal direction and the Y direction. The second suction cup 42 can suck and hold the glass product 7 at the conveying end of the glass positioning and conveying mechanism 2 under negative pressure. The control system controls the movement of the second planar motion mechanism and the start and stop of the negative pressure of the second suction cup 42. By the movement of the second planar motion mechanism in the longitudinal direction and the X direction, the glass product 7 on the glass positioning and conveying mechanism 2 is transported into the tray cavities of the blanking bin 4. The transportation of the glass product 7 is achieved by the negative pressure suction of the second suction cup 42. For the scheme of synchronously collecting materials into four bins for the four glass products 7, it is optimal to set four glass blanking and handling mechanisms 6, which are respectively used to transport the glass products 7 on different glass positioning and conveying mechanisms 2 to the corresponding blanking bins 4 for positioning. The four glass blanking and handling mechanisms 6 transport synchronously, with a fast transportation speed, which is beneficial to improving the efficiency of collecting materials into bins for the glass product 7. Among them, the second planar motion mechanism includes a second X-direction track 43, a second X-direction slider 44, a third Z-direction slider 45, a second X-direction driving device 46, and a third Z-direction driving device 47. The second X-direction track is fixedly installed on the frame. The second X-direction slider is installed on the second X-direction track so as to be able to slide along the X direction. The third Z-direction slider is installed on the second X-direction slider so as to be able to slide along the longitudinal direction. The second X-direction driving device and the third Z-direction driving device respectively drive the second X-direction slider and the third Z-direction slider to move. Among them, the second X-direction driving device and the third Z-direction driving device can be cylinders or a motor driving a screw-nut mechanism. The movement of the second suction cup 42 on the two-dimensional plane is realized by the movement of the slider in two mutually perpendicular directions. In addition to this structure, it can also be a multi-joint manipulator or a horizontal rotating arm mechanism, etc., to realize that the tray gripper 35 transports the tray in the empty tray bin 3 into the blanking bin 4. It is optimal to install a traceless suction cup sleeve on the second suction cup 42 to avoid leaving marks on the surface of the glass product 7 by the suction cup.
