Description

Technical Field

[0001] The present invention belongs to the technical field of plastic pallet processing, and specifically relates to a plastic pallet stacking and transferring device. Background Art

[0002] A plastic pallet is a logistics unit used in conjunction with logistics equipment such as forklifts and shelves. It can be used to store, load, and transport goods. It is one of the essential logistics equipment in modern logistics warehousing. After the plastic pallets are produced, they generally need to be stacked first and then transferred. The stacked plastic pallets form a compact whole, which is more convenient for transportation.

[0003] The patent with the publication number CN220282582U discloses a plastic pallet stacking and transferring device, including a mounting frame. A moving mechanism is arranged at the bottom of the mounting frame, and a lifting mechanism is arranged on the inner wall of the mounting frame. The lifting mechanism includes a mounting slide rail, a lead screw, a sliding seat, and a placing plate. A positioning mechanism is arranged on the side wall of the placing plate, and a pushing mechanism is arranged on the side wall of the sliding seat. By providing a lifting mechanism, the device is moved to the discharging position of the plastic pallets through the moving mechanism. The motor cooperates with the lead screw to drive the sliding seat to move up and down, and then drives the placing plate to move, moving the placing plate to a suitable height. The plastic pallets are stacked and placed on the placing plate. The plastic pallets are positioned and clamped through the positioning mechanism, and can be adaptively placed and stacked according to plastic pallets of different sizes, avoiding the unstable situation of the stacked plastic pallets during transfer, enabling the device to stably complete the transfer task, and improving the practicability of the device.

[0004] However, the above technical solution still has the following deficiencies in the actual application process:

[0005] When it is necessary to unload the stacked plastic pallets, the plastic pallets are pushed out of the device through a push plate to achieve the unloading operation. However, in some cases, it is necessary to divide the stacked plastic pallets into several batches and unload them to different positions to meet the actual warehousing needs. When all the stacked plastic pallets are pushed down by the push plate at once, this demand cannot be met. Moreover, during the stacking and transferring process of the plastic pallets, if it is found that a certain plastic pallet is damaged or deformed, etc., in order to ensure the stability of the placement of the remaining plastic pallets, it is necessary to take out the damaged or deformed plastic pallet and replace or repair it. When the damaged or deformed plastic pallet is between multiple plastic pallets, it is not easy to take it out, thereby affecting the stability of the placement of the remaining plastic pallets.

[0006] Therefore, the present invention provides a plastic pallet stacking and transferring device. Summary of the Invention

[0019] The beneficial effects of the present invention are as follows:

[0020] 1. For a plastic pallet stacking and transferring device of the present invention, the plastic pallets to be transferred are stacked on the discharging plate, and the height of the discharging plate can be adjusted by using a scissor lifting mechanism to more conveniently place the plastic pallets. Then, the first bidirectional threaded rod is rotated by the fifth motor, and the second bidirectional threaded rod is rotated by the fourth motor to adjust the distance between multiple limiting plates, so that the inner included angle of the limiting plates can fit with the four corners of the plastic pallet to clamp the plastic pallet. Then, the plastic pallet is transferred to a specified position by using the moving wheels, thereby ensuring the stability of the plastic pallet during the transfer process and preventing it from shifting and slipping.

[0021] 2. A plastic pallet stacking and transferring device according to the present invention utilizes an adjustable separation mechanism to divide plastic pallets into upper and lower parts according to the number of plastic pallets to be unloaded. The upper part of the plastic pallets is placed on the second pallet, and the lower part of the plastic pallets is placed on the unloading plate. At this time, the unloading plate and the second pallet are respectively driven to rotate, so that the plastic pallets on the unloading plate and the second pallet slide down in batches, thereby realizing the control of the single unloading quantity. Moreover, when it is necessary to increase the number of batches, after the plastic pallets on the unloading plate are unloaded, the unloading plate can be driven to rise to receive the plastic pallets on the second pallet, and then the second pallet is driven to move out from the gaps between the plastic pallets, so that multiple plastic pallets are again placed on the unloading plate. By repeating the above operations and dividing the plastic pallets on the unloading plate into upper and lower parts again, the plastic pallets can be placed in different unloading positions in multiple times, thus meeting different warehousing requirements. And when a certain plastic pallet is squeezed and deformed during the transfer of plastic pallets and needs to be taken out and replaced, first repeat the above operations to divide the plastic pallets into upper and lower parts, lower the unloading plate to align the first pallet with the gaps of the upper-layer plastic pallets of the plastic pallet to be taken out, then drive the first pallet to extend into the gaps and drive the first pallet to rise again, so as to separate the plastic pallet to be taken out from the other plastic pallets. At this time, drive the second displacement plate to rotate, and the plastic pallet can slide out and be replaced, and then the plastic pallet is reset, thus avoiding the situation that the stability of the stacking of the other plastic pallets is affected due to the plastic pallet being squeezed and deformed and being difficult to take out.

On one side of the left end surface of the second displacement plate 38, a sixth motor 31 is fixedly connected.

[0043] On one side of the rear end face of the lifting plate 24, a first electric push rod 27 is fixedly connected. The piston end of the first electric push rod 27 is fixedly connected to one side of the rear end face of the first fixing plate 16.

[0044] On one side of the lower end face of the placing plate 3, a hydraulic cylinder 37 is rotatably arranged. The piston end of the hydraulic cylinder 37 is rotatably connected to one side of the bottom of the unloading plate 4.

[0045] Specifically, when the existing plastic pallet stacking and transferring device is in use, when it is necessary to unload the stacked plastic pallets, a push plate is used to push the plastic pallets out of the device to achieve the unloading operation. However, in some cases, it is necessary to divide the stacked plastic pallets into several batches and unload them to different positions to meet the actual warehousing requirements. When all the stacked plastic pallets are pushed down by the push plate at once, this demand cannot be met. Moreover, during the stacking and transferring process of plastic pallets, if it is found that a certain plastic pallet is damaged or deformed, etc., in order to ensure the stability of the rest of the stacked plastic pallets, it is necessary to take out the damaged or deformed plastic pallet and replace or repair it. When the damaged or deformed plastic pallet is between multiple plastic pallets, it is not easy to take it out, which will affect the stability of the rest of the stacked plastic pallets;

[0046] Therefore, to solve the above problems, when this embodiment is in use, when it is necessary to unload the plastic pallets on the unloading plate 4, the plurality of limiting plates 2 can be driven to move away from the plastic pallets, and then the hydraulic cylinder 37 is used to drive the unloading plate 4 to rotate, so that the rear end thereof is lifted. At this time, the plurality of plastic pallets on the unloading plate 4 will slide forward and fall to the designated unloading position, thus realizing the automatic unloading of the plastic pallets;

[0047] When it is necessary to unload plastic pallets in batches, according to the number of plastic pallets to be unloaded, the scissor lift mechanism 5 is used to drive the unloading plate 4 to rise. Since there are multiple support legs at the bottom of the plastic pallet, the gaps between the support legs are applicable to the operations of various equipment such as hydraulic trucks and forklifts. According to the position of the gaps, the motor six 31 is used to drive the bidirectional threaded rod four 29 to rotate, adjust the distance between the two trays two 28, so that the two trays two 28 can be aligned with the gaps. Then, the electric push rod two 34 is used to drive the tray two 28 to extend into the gaps, and the upper end surface of the tray two 28 is attached to the bottom of the plastic pallet. Then, the scissor lift mechanism 5 is driven to lower the plastic pallet. At this time, the plastic pallet is divided into two parts, the upper part of the plastic pallet is placed on the tray two 28, and the lower part of the plastic pallet is placed on the unloading plate 4. At this time, the unloading plate 4 is driven to rotate, so that the plastic pallet on the unloading plate 4 slides off, and the control of the unloading quantity can be realized. By driving the displacement plate two 38 to rotate with the motor seven 33, the tray two 28 can be tilted, so that the plastic pallet above it slides off, and unloading is realized again. At this time, the plastic pallet is only unloaded in two batches. When it is necessary to increase the number of batches, after the plastic pallet on the unloading plate 4 is unloaded, the unloading plate 4 can be driven to rise to receive the plastic pallet on the tray two 28. Then, the tray two 28 is driven to move out of the gap of the plastic pallet, so that multiple plastic pallets are placed on the unloading plate 4 again. Repeat the above operations, and divide the plastic pallet on the unloading plate 4 into two parts again, so that the plastic pallet can be placed in different unloading positions in batches, thus meeting different warehousing requirements;

[0048] When a certain plastic pallet is squeezed and deformed during the transfer process of the plastic pallet and needs to be taken out and replaced, first repeat the above operations to divide the plastic pallet into two parts, and the plastic pallet to be replaced is at the bottom layer of the upper part. The unloading plate 4 descends, and then the motor one 8 is used to drive the threaded rod 10 to rotate, so that the lifting plate 24 descends, and the motor two 13 is used to drive the bidirectional threaded rod one 14 to rotate, adjust the distance between the two trays one 11, so that the tray one 11 is aligned with the gap of the upper plastic pallet of the plastic pallet to be taken out. Then, the electric push rod one 27 is used to drive the tray one 11 to extend into the gap, and the tray one 11 is driven to rise again, so that the plastic pallet to be taken out can be separated from the other plastic pallets. At this time, by driving the displacement plate two 38 to rotate with the motor seven 33, the plastic pallet can slide out and be replaced, and then the plastic pallet is reset; thus avoiding the situation that the plastic pallet is squeezed and deformed and is not easy to take out, which affects the stacking stability of the other plastic pallets.

[0049] Working principle: Stack the plastic pallets to be transferred on the discharge plate 4. Moreover, the scissor lift mechanism 5 can be used to adjust the height of the discharge plate 4 to facilitate the placement of plastic pallets more conveniently. Then, the motor five 23 drives the bidirectional threaded rod three 21 to rotate, and the motor four 18 drives the bidirectional threaded rod two 19 to rotate to adjust the distance between multiple limit plates 2, so that the inner angles of the limit plates 2 can fit with the four corners of the plastic pallet to clamp the plastic pallet. Then, the mobile wheels 36 are used to transfer the plastic pallet to the designated position, thus ensuring the stability of the plastic pallet during the transfer process and preventing it from shifting and slipping easily. When it is necessary to unload the plastic pallets on the discharge plate 4, the multiple limit plates 2 can be driven away from the plastic pallet, and then the hydraulic cylinder 37 is used to drive the discharge plate 4 to rotate, raising its rear end. At this time, the multiple plastic pallets on the discharge plate 4 will slide forward and fall to the designated unloading position, thus realizing the automatic unloading of the plastic pallets; when it is necessary to unload the plastic pallets in batches, according to the number of plastic pallets to be unloaded, the scissor lift mechanism 5 is used to drive the discharge plate 4 to rise. Since the plastic pallet has multiple support legs at the bottom, the gaps between the support legs are suitable for the operation of various equipment such as hydraulic trucks and forklifts. That is, according to the position of the gaps, the motor six 31 drives the bidirectional threaded rod four 29 to rotate to adjust the distance between the two support plates two 28, so that the two support plates two 28 can be aligned with the gaps. Then, the electric push rod two 34 is used to drive the support plate two 28 to extend into the gaps, and the upper end surface of the support plate two 28 fits with the bottom of the plastic pallet. Then, the scissor lift mechanism 5 is driven to drive the plastic pallet to descend. At this time, the plastic pallet is divided into two parts, the upper part of the plastic pallet is placed on the support plate two 28, and the lower part of the plastic pallet is placed on the discharge plate 4. At this time, the discharge plate 4 is driven to rotate, and the plastic pallets on the discharge plate 4 will slide, thus realizing the control of the unloading quantity. By driving the displacement plate two 38 to rotate with the motor seven 33, the support plate two 28 can be tilted to make the plastic pallet above it slide, realizing unloading again. At this time, the plastic pallet is only unloaded in two batches. When it is necessary to increase the number of batching times, after the plastic pallets on the discharge plate 4 are unloaded, the discharge plate 4 can be driven to rise to receive the plastic pallets on the support plate two 28. Then, the support plate two 28 is driven to move out of the gap of the plastic pallet, so that the multiple plastic pallets are placed on the discharge plate 4 again. Repeat the above operation to divide the plastic pallets on the discharge plate 4 into two parts again, and the plastic pallets can be placed in different unloading positions in batches, thus meeting different warehousing requirements;When a plastic pallet is squeezed and deformed during the transfer process and needs to be taken out and replaced, first repeat the above operations to divide the plastic pallets into upper and lower parts, and the plastic pallet to be replaced is at the bottom layer of the upper part. The unloading plate 4 descends, and then the motor 1 8 drives the threaded rod 10 to rotate, causing the lifting plate 24 to descend. The motor 2 13 drives the bidirectional threaded rod 1 14 to rotate to adjust the distance between the two support plates 1 11, so that the support plate 1 11 aligns with the gap of the upper plastic pallet of the plastic pallet to be taken out. Then, the electric push rod 1 27 drives the support plate 1 11 to extend into the gap, and the support plate 1 11 is driven to rise again, so that the plastic pallet to be taken out can be separated from the other plastic pallets. At this time, the motor 7 33 drives the displacement plate 2 38 to rotate, so that the plastic pallet can slide out and be replaced, and then the plastic pallet is reset; thus avoiding the situation that the stacking stability of the other plastic pallets is affected because the plastic pallet is squeezed and deformed and is not easy to take out.
