Technical Field

[0001] The present invention relates to the technical field of palletizers, in particular to a plate palletizer. Background Art

[0002] During the production process, composite insulation boards need to be stacked by a palletizer before transportation. Existing palletizers, such as a new L-plate palletizer disclosed in the authorization announcement number CN218402235U, solve the problem in the existing technology that the transfer and stacking of L-plate profiles in today's duct profile production has always been done manually, and the market has not yet adopted mechanical completion. The boom is movably connected to the bottom of the top bracket through a driving component, and the bottom side of the boom is connected to the plate body through a folding and telescopic hanger. Several groups of suction cup assemblies are provided at the bottom of the plate body, and a conveyor rack is provided on one side of the placement table. The L-shaped plate is placed on the top of the conveyor rack, and a conveyor belt is installed at the top center of the placement table, which is convenient for automatically driving the L-shaped plate to move and stack. It saves time and effort and greatly improves the stacking efficiency.

[0003] The existing palletizer transports the plates to one side of the palletizer through a conveyor, and the plates are transported and stacked by the suction cups on the palletizer, which is similar to the above-mentioned existing technology. However, when the plates are transported, multiple plates may be stacked in a small number for transfer. At this time, the suction cups cannot transfer multiple plates at the same time. Some palletizers use clamps to clamp and transfer the plates, but when multiple plates are clamped at the same time, there is a possibility that they may fall. Summary of the Invention

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention sets an arc-shaped support plate by sliding at the lower end of the clamping plate, and sets a conveyor belt on one side of the stacking machine frame. At this time, the fixed plate is controlled to move above the plate, and the clamping plates are located on both sides of the plate. The setting of the conveyor belt is convenient for clamping the plate. During the clamping and transportation process, when a plate falls, it is supported and blocked by the arc-shaped support plate to prevent the plate from falling.

The rectangular rod 18 is slidably connected to the rectangular cylinder 17. A connecting rod 15 is fixedly connected to one side of the lower end of the first support column 16. One end of the connecting rod 15 passes through the second support column 13 and is slidably connected thereto. The external equipment conveys the plate to the two conveyor belts 19 and then clamps it. The two sides of the plate are respectively located on both sides of the two conveyor belts 19, which is convenient for clamping the two sides of the plate by the clamping plate 3. The distance between the two conveyor belts 19 is adjustable, which is suitable for conveying and stacking plates of different widths.

[0028] A groove 11 is provided on the inner side of the splint 3, and a buffer clamp is slidably provided in the groove 11. Connecting grooves 27 communicating with the groove 11 are provided on both sides of the lower end of the fixed plate 6. A detection component is installed on the fixed plate 6, and a telescopic component for controlling the movement of the detection component is slidably provided in the connecting groove 27 and the groove 11. The movement of the buffer clamp is used to control the movement of the buffer clamp. A power component for controlling the movement of the splint 3 is installed on the fixed plate 6. The power component includes a first motor 9 fixedly mounted on the fixed plate 6, and a gear 28 is fixedly mounted on the output end of the first motor 9. A rack 30 meshing with the gear 28 is fixedly mounted on one side of the splint 3. A limiting groove 29 is provided at the lower end of the fixed plate 6, and a limiting block 22 slidably connected to the limiting groove 29 is fixedly connected to the upper end of the splint 3 The lower end of the splint 3 is slidingly provided with an arc-shaped support plate 4, and the lower end of the splint 3 is provided with a slide groove 32 connected to the groove 11.

The fixed plate 6 drives the splint 3 to be located on both sides of the plate. By starting the first motor 9, the splints 3 on both sides are controlled to move to clamp the plate. During the transport and stacking process, when a plate falls, it is supported and blocked by the arc-shaped support plate 4 to prevent the plate from falling. When stacking, the plate at the lower end is squeezed by the plate to move the arc-shaped support plate 4 to prevent the arc-shaped support plate 4 from being clamped between multiple plates during stacking, causing the plate to be skewed.

When the clamping plate 2 is controlled to move to clamp the plate by the clamping plate 3, when the clamping plate 2 first contacts the plate, the position of the plate that is skewed during the transmission process can be corrected, and the detection component includes a transparent cylinder 38 fixedly mounted on the fixed plate 6, a circular shell 37 filled with colored liquid is slidably arranged in the transparent cylinder 38, a color recognition scanner 7 is arranged on one side of the transparent cylinder 38, a controller 8 is fixedly mounted on the fixed plate 6, and the first motor 9, the controller 8 and the color recognition scanner 7 are electrically connected (this setting is a prior art and will not be described in detail here), and the telescopic component includes a toothed roller 25 rotatably mounted in the groove 11 The side wall of the groove 11 is slidingly provided with a second serrated plate 24 that meshes with the tooth roller 25, and a push plate 26 is slidingly provided in the connecting groove 27. A telescopic spring 23 is fixedly provided between the push plate 26 and the connecting groove 27, and the push plate 26 is fixedly connected to the circular shell 37. After correction, the clamping plate 2 clamps multiple plates. During the clamping process, it will push the circular shell 37 filled with colored liquid to move upward. At this time, through the cooperation of the color recognition scanner 7 and the controller 8, the first motor 9 can be controlled to stop working to avoid continuing to control the movement of the two clamping plates 3, causing the plates to be damaged by excessive squeezing. Plates of different widths can be clamped and can be detected to avoid excessive clamping pressure (both color recognition scanners 7 need to scan the circular shell 37 filled with colored liquid before the first motor 9 will be controlled to stop working, because during correction, one side of the clamping plate 2 may first contact the plate and push the plate to move).

[0030] As a further technical solution of the present invention, a spiral groove 36 is provided on the inner wall of the transparent cylinder 38, and a sliding ball 35 slidably connected to the spiral groove 36 is fixedly installed on one side of the circular shell 37. A U-shaped frame 34 is fixedly installed on the upper end of the fixed plate 6. The fixed plate 6 is located on the outside of the transparent cylinder 38 and is slidably connected thereto. In the process of controlling the upward movement of the circular shell 37, the transparent cylinder 38 can be driven to rotate, and the outside of the transparent cylinder 38 is in sliding contact with the U-shaped frame 34. The outside of the transparent cylinder 38 that has been exposed to the outside for a long time can be cleaned to avoid affecting the scanning of the color recognition scanner 7.

[0031] During operation, the self-locking travel wheel 14 is pushed to move in advance according to the width of the plate, the distance between the two conveyor belts 19 is controlled, and then the self-locking travel wheel 14 is self-locked;

[0032] The external equipment transfers the plate to the conveyor belt 19, and the second motor 21 is started to work. The conveyor belt 19 is driven to move and transport the plate through the cooperation of the pulley 20, the rectangular rod 18 and the rectangular cylinder 17. Then the stacker is controlled to work, and the fixed plate 6 is moved to the top of the plate. Then the hydraulic rod 5 is started to move downward, and the fixed plate 6 drives the clamping plate 3 to be located on both sides of the plate.

[0033] Then the first motor 9 is started to drive the gear 28 to rotate, and the gear 28 drives the two racks 30 to move, controlling the two clamping plates 3 to move toward the plate, and the limit block 22 slides in the limit slot 29;

[0034] The clamping plate 3 drives the clamping plate 2 to move and clamp the plate. When the clamping plate 2 first contacts the plate, the position of the plate that is skewed during the transmission process can be corrected. The arc-shaped support plate 4 is located below the plate (when adjusting the distance between the two conveyor belts 19, the two sides of the plate are controlled to be located on both sides of the two conveyor belts 19, respectively, so that the arc-shaped support plate 4 is located below the plate when the clamping plate 3 clamps the two sides of the plate).

[0035] When the clamping plate 2 clamps the plate, it slides in the groove 11, the connecting spring 31 is squeezed, and when the clamping plate 2 drives the first serrated plate 33 to abut against the side wall of the groove 11, the circular shell 37 filled with colored liquid will be controlled to abut against the upper wall of the transparent cylinder 38 (the first serrated plate 33 drives the toothed roller 25 to rotate, the toothed roller 25 drives the second serrated plate 24 to move upward, the second serrated plate 24 pushes the push plate 26 to move upward, the telescopic spring 23 is squeezed, and the push plate 26 pushes the circular shell 37 to move upward. When the two color recognition scanners 7 scan the colored liquid, the first motor 9 will be controlled to stop working to avoid continuing to control the movement of the two clamping plates 3, which will cause the plate to be excessively squeezed and damaged. Plates of different widths can be clamped and can be tested to avoid excessive clamping pressure.

[0036] In the process of controlling the circular housing 37 to move upward, the sliding ball 35 slides in the spiral groove 36, which can drive the transparent cylinder 38 to rotate. The outer side of the transparent cylinder 38 is in sliding contact with the U-shaped frame 34, which can clean the outer side of the transparent cylinder 38 that has been exposed to the outside for a long time, so as to avoid affecting the scanning of the color recognition scanner 7;

[0037] After the plates are clamped, during the transfer and stacking process, if a plate falls, the arc-shaped support plate 4 is used to support and block it to prevent the plate from falling.

[0038] During stacking, the hydraulic rod 5 controls the clamping plate 3 to move downward, and the curved support plate 4 is squeezed by the plate at the lower end to move, so as to avoid the curved support plate 4 being clamped between multiple plates during stacking, causing the plates to skew;

[0039] After stacking, the first motor 9 can also be used to control the movement of the clamping plates 3 on both sides to perform position correction on the stacked plates. During correction, the arc-shaped support plate 4 can slide without affecting the correction result.
