Description
Technical Field
[0001] The utility model relates to the technical field of warehouse logistics, in particular to a pallet transport device. Background Art
[0002] In the modern warehousing and logistics system, pallets are generally pulled by ground cows, so that the pallets drive the goods above to move within the factory. After the goods are taken out, the empty pallets are pulled to the AGV trolley stop, the pallets are transferred to the AGV trolley, and the AGV trolley transports the pallets to the pallet lifting device. The pallet lifting device stacks all the empty pallets together to avoid occupying space in the factory. The stacked empty pallets will be uniformly moved by forklifts and transported to the designated location.
[0003] The existing technology uses manual operation on the ground bull, which has two sets of arms. The two sets of arms on the ground bull need to be docked on both sides of the AGV cart, but the docking position of the arms on both sides is different from the AGV cart each time, which will make the placement position of the pallet on the AGV cart different each time. Therefore, the position of the pallet carried by the AGV cart will change each time, and the distance between each set of pallets and the brackets of the lifting devices on both sides is different, resulting in that during the stacking process of the pallets, the placement positions of all pallets are staggered with each other, resulting in multiple groups of pallets being prone to shaking after being stacked up and down, and the stacked pallets will tip over when transported by forklifts. At the same time, the AGV cart will also deviate from the target driving trajectory during transportation, which will aggravate the error in the placement position of the stacked pallets in the lifting device and increase the amplitude of shaking.

[0014] Beneficial effect: The position of the pallet on the fork is adjusted by the push plate on the limiting body. Since the push plates on both sides move the same distance each time, the distances between the two sides of the pallet and the limiting body will be the same after the pallet is pushed by the push plates, so that each time the pallet is transported between the limiting bodies, the axis of the pallet coincides with the axis of symmetry formed by the limiting bodies on both sides after adjustment, and the pallet enters the guide plate of the lifting body under the drive of the fork. Since the fork moves in a straight line, the pallet will not move perpendicular to the length direction of the fork, so each time the pallet will be placed on the same position on the guide plate by the fork, and the distances between the two sides of the pallet and the bracket are the same. When the pallets are stacked by the lifting body, since the distances between the two sides of each group of pallets and the bracket are the same, the stacked pallets coincide with each other in the projection perpendicular to the ground, thereby reducing the amplitude of the shaking of the pallets after stacking.

A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0026] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0027] Under the existing technology, since there will be a deviation between the position where the AGV is manually parked and the position of the pallets on the AGV, the position of the pallets on the AGV will be inconsistent. When the pallets are finally transported to the lifting device, the stacked pallets will be staggered with each other, causing the stacked pallets to shake.
[0028] In order to solve the above problems, Figures 1 to 7As shown, the utility model provides a pallet transport device, including a limiting body 1, a transport body 2 and a lifting body 3, the transport body 2 includes a workbench 21 and a fork 22, the fork 22 is slidably installed on the workbench 21, the fork 22 reciprocates along its own length direction, along the length direction of the fork 22, one end of the fork 22 is installed with the limiting body 1, the other end of the fork 22 is installed with the lifting body 3, the fork 22 is plugged into the bottom of the pallet 4; the transport body 2 of the utility model is a two-way fork 22, and its structure is the prior art and is not repeated here, wherein the fork 22 is responsible for transporting the pallet 4 on one side of the limiting body 1 to the lifting body 3, to realize the transfer of the pallet 4, so that the pallet 4 can move along a straight line.
[0029] The positioning body 1 of the utility model includes two groups, a pallet 4 is placed between the positioning bodies 1, a fork 22 moves between the positioning bodies 1, and the fork 22 abuts against the bottom surface of the pallet 4. The positioning body 1 includes a support frame 11, a telescopic member, and a push plate 13. The support frame 11 is equipped with a telescopic member, and the push plate 13 abuts against the side of the pallet 4. The telescopic member drives the push plate 13 to move perpendicularly to the length direction of the fork 22, and the two groups of push plates 13 move the same distance. The AGV trolley will transport the pallet 4 between the positioning bodies 1, and then transport the pallet 4 to the lifting body 3 through the fork 22. Since the push plates 13 on both sides move toward each other at the same time and move the same distance, they will not stop until all the push plates 13 on both sides are in contact with the pallet 4. The position of the pallet 4 can be corrected by the push plates 13 on both sides, so that the axis of the pallet 4 moves to coincide with the symmetry axis of the two groups of positioning bodies 1. By moving the pallet 4 by the push plate 13, the deviation of each group of pallets 4 received by the AGV trolley from the ground bull can be corrected, so that the axis of each group of pallets 4 after receiving the push plate 13 is coincident with the symmetry axis, and the fork 22 moves the pallet 4 into the lifting body 3 along the symmetry axis in sequence, and finally the pallets 4 are stacked in sequence by the lifting body 3. At this time, the axis of the stacked pallets 4 still coincides with the symmetry axis, so that the stacked pallets 4 overlap in the projection perpendicular to the ground, reducing misalignment and reducing the amplitude of the shaking of the stacked pallets 4. The limiting body 1, the transport body 2 and the lifting body 3 of the utility model are placed in sequence, which can save space and enable the pallets 4 to be quickly stacked.
[0030] The lifting body 3 of the utility model includes a fixed frame, and brackets 31 are installed on both sides of the fixed frame. Lifting plates 32 are slidably installed on the brackets 31, and guide plates 33 are installed between the lifting plates 32. The fork 22 moves to the guide plates 33 between the lifting plates 32, and the guide plates 33 abut against the bottom surface of the pallet 4. The lifting plate 32 moves perpendicular to the ground. Whenever a new pallet 4 enters onto the guide plates 33, the lifting plate 32 will drop, so that after the new pallet 4 enters between the brackets 31, the new pallet 4 can be placed on the upper side of the previous group of pallets 4, and the pallets 4 are stacked by placing the new pallets 4 on top of the previous pallet 4 in sequence. Finally, after a certain number of pallets 4 are placed, the pallet 4 is removed from the lifting body 3 by a forklift and transported.
[0031] The telescopic member of the utility model includes an electric cylinder 12, which is fixed on the support frame 11, and a telescopic rod is slidably installed in the electric cylinder 12. The electric cylinder 12 pushes the telescopic rod to move back and forth along its own axis. The telescopic rod is connected to the push plate 13, and the telescopic rod is perpendicular to the length direction of the fork 22. When the AGV trolley reaches between the limit bodies 1, the electric cylinder 12 is started, pushing the telescopic rod to extend, so that the push plate 13 abuts against the two sides of the pallet 4, eliminating the position deviation of the pallet 4 and reducing the shaking amplitude of the stacked pallets 4.
[0032] The telescopic member of the present utility model also includes a fixed frame 14, which is fixedly connected to the telescopic rod. The cross-section of the fixed frame 14 is U-shaped, and the notch of the fixed frame 14 faces the tray 4. The push plate 13 is fixed in the groove body of the fixed frame 14 through a spring 15. An adjusting hole 141 is formed on the fixed frame 14, and a threaded sleeve 161 is formed on the limit plate 16. The threaded sleeve 161 is inserted into the adjusting hole 141, and the limit plate 16 is fixed in the fixed frame 14. A moving rod 17 is inserted in the spring 15, and a thread is formed on the moving rod 17. One end of the moving rod 17 abuts against the push plate 13, and the other end is screwed into the threaded sleeve 161.
[0033] By rotating the moving rod 17, the moving rod 17 can be moved back and forth along its own axis, thereby driving the push plate 13 to move relative to the fixed frame 14. By adjusting the relative distance between the push plate 13 and the fixed frame 14, the spacing between the two groups of push plates 13 can be adjusted to adapt to trays 4 of different sizes. The limit assembly of the utility model can adjust the position of trays 4 of different sizes, and the adaptability is higher.
[0034] The forks 22 include two groups, and two groups of grooves 41 are usually formed on the bottom surface of the pallet 4. The forks 22 are inserted into the bottom surfaces of the grooves 41, and the forks 22 correspond to the grooves 41 one by one. The grooves 41 of the pallet 4 are overlapped on the forks 22. After the AGV trolley transports the pallet 4 to between the limit assemblies, the forks 22 can move to one side of the limit assemblies and be inserted into the above-mentioned grooves 41. When the push plate 13 completes the adjustment of the pallet 4, the forks 22 will lift the pallet 4 and drive the pallet 4 to move into the lifting body 3.
[0035] The fork 22 of the utility model is provided with a sliding seat 23 under it, and the fork 22 slides on the sliding seat 23, and the workbench 21 is provided with a lifting cylinder, and the lifting cylinder pushes the sliding seat 23 to move perpendicular to the ground, so that the fork 22 can have the ability to move perpendicular to the ground, so that the placement of the limiting body 1 and the lifting body 3 can be more free, and after the fork 22 receives the pallet 4 from the AGV trolley, the fork 22 is lifted to facilitate the transportation of the pallet 4 to the lifting body 3, so that the pallet 4 can be stacked, and by placing the transport body 2 between the limiting body 1 and the lifting body 3, the pallet transport device of the utility model can be placed at any position in the factory, and the transport body 2, the limiting body 1 and the lifting body 3 are placed adjacent to each other to save space.
[0036] The lifting body 3 also includes a boosting component, which includes a guide roller 34 and a first motor. The first motor drives the guide roller 34 to rotate. The guide roller 34 is installed between the lifting body 3 and the transport body 2, and the guide roller 34 abuts against the upper surface of the pallet 4.
[0037] The guide roller 34 of the utility model rotates, and the pallet 4 on the fork 22 can be pushed from the fork 22 to the guide plate 33. The guide plate 33 is equipped with rollers, and the rollers can drive the pallet 4 to move to a fixed position, and then the rollers stop rotating to prevent the next group of pallets 4 from sliding when moving to the upper side of the previous pallet 4, and to prevent the new pallet 4 from being unable to move to the specified position. Since the previous group of pallets 4 is fixed on the rollers, the new pallet 4 will move to the specified position under the push of the guide roller 34. The guide roller 34 can make the pallet 4 move more quickly. After the pallet 4 on the fork 22 is pushed out by the guide roller 34, it will move back to the limit assembly.
[0038] A second motor and a driving wheel 35 are installed in the lifting body 3 of the utility model. The second motor drives the driving wheel 35 to rotate. The driving wheel 35 is installed on both sides of the lifting plate 32. Two groups of right-angle beams 311 perpendicular to the ground are formed in each group of brackets 31. The driving wheel 35 is pressed on the right-angle beam 311, and the driving wheel 35 and the right-angle beam 311 correspond one to one.
[0039] The driving wheel 35 rotates on the support beam to move along the length direction of the right-angle beam 311. After placing a new pallet 4, the driving wheel 35 moves downward to leave a receiving position for the next group of pallets 4, so that the pallets 4 can be stacked on the lifting assembly. The guide plate 33 has a moving space for the forklift arm to move the upper side of the guide plate 33 from the bottom of the guide plate 33 to lift the pallet 4.
