By placing the stacked pallets 6 on the first conveyor line 1, the reversing device 11 sends the stacked pallets on the first conveyor line 1 to the transition conveyor line 5, and the transition conveyor line 5 transfers the stacked pallets 6 to the top of the lifting device 4, so that the stacked pallets 6 are lifted by the lifting device 4, and the stacked pallets on the lifting device 4 are sent to the second conveyor line 2 by the destacking device 3, and the stacked pallets 6 are separated, so that the second conveyor line 2 outputs the separated pallets 6 one by one.
[0028] Reference Figure 1 As shown, further, a guiding device 51 is provided on the transition conveyor line 5, and the guiding device 51 includes a centering guide plate. The centering guide plates are a pair and are respectively fixed on the sides of the transition conveyor line 5, and the centering guide plates are in an "eight" shape. When the pallets 6 stacked on the first conveyor line 1 enter the transition conveyor line 5, the pallets 6 on the transition conveyor line 5 are transported in the center under the guiding action of the centering guide plate, so as to prevent the pallets 6 stacked on the transition conveyor line 5 from deviating from the center position during the transportation process and affecting the subsequent destacking work.
[0029] Reference Figures 1 - 3 As shown, the depalletizing device 3 includes a depalletizing platform 31, a clamping depalletizing mechanism 32, a walking mechanism 33, and a depalletizing frame 35. The transition conveyor line 5 is arranged in the depalletizing frame 35. The depalletizing platform 31 is horizontally slidably arranged above the transition conveyor line 5.

The upper part of the jacking block 42 is rotatably provided with rollers that slide in the groove seats 412. When the transition conveyor line 5 transports the stacked pallets to the top of the jacking device 4, the jacking drive device drives the jacking block 42 to rotate counterclockwise, thereby linking the jacking seat 411 to rise and expose the surface of the transition conveyor line 5, thereby lifting the pallet 6 on the transition conveyor line 5, so that the clamping and destacking mechanism 32 can better clamp the stacked pallets.
[0031] In addition, the lifting platform in this embodiment is not limited to the lifting method using a motor or a cam, but may also be lifted by a cylinder, a push rod, or the like.
[0032] Reference Figure 3 , Figure 5 , Figure 6 As shown, specifically, the clamping and destacking mechanism 32 includes a clamping base 321, a destacking roller 322, and a clamping drive device 323. The clamping base 321 is slidably arranged on the bottom surface of the destacking platform 31, and the destacking roller 322 is rotatably arranged at the lower part of the clamping base 321. The clamping drive device 323 is fixedly installed on the destacking platform 31. In this embodiment, the clamping drive device 323 preferably adopts an electric push rod, and its telescopic end is connected to the clamping base 321 through a joint bearing, so that when the jacking device 4 lifts the stacked pallet 6 upward, the clamping drive device 323 drives the stacking pallet 6 to move upward. The clamping base 321 drives the destacking roller 322 to move similarly, so that the destacking roller 322 is used to clamp the top edge of the topmost pallet for clamping, and a destacking drive device is fixedly installed on one side of the clamping base 321. The destacking drive device preferably adopts a servo motor, and the destacking drive device is connected to the destacking roller 322 through transmission, so that the destacking roller 322 is driven to rotate through the destacking drive device, and in this embodiment, electromagnetic braking is adopted between the destacking drive device and the destacking roller 322, so as to prevent the destacking roller from rotating due to the action of external force during the process of clamping the pallet.
[0033] A guide plate 325 is provided on the inner side of the clamping base 321, so that after the destacking roller 322 clamps the stacked pallet 6, it can use the guide plate 325 to align with the stacked pallet to prevent the stacked pallet from tilting during the clamping process and affecting the normal separation of the pallets. In this embodiment, the guide plate 325 is preferably made of nylon plate to improve the wear resistance of the guide plate.
[0034] Refer to Figure 1 and Figure 4 As shown, further, the traveling mechanism 33 includes a plurality of traveling wheels 331 and a traveling driving device 332. Mounting plates 311 are respectively arranged on both sides of the palletizing and depalletizing platform 31. The plurality of traveling wheels 331 are rotatably arranged on the mounting plates 311 of the palletizing and depalletizing platform 31. In this embodiment, the traveling wheels 331 are arranged up and down respectively, so that the traveling wheel 342 is in sliding fit with the palletizing and depalletizing rack 35. The traveling driving device 332 is fixedly installed on the palletizing and depalletizing rack 35. In this embodiment, the traveling driving device 332 preferably adopts an electric push rod, and its telescopic end is connected to the palletizing and depalletizing platform 31 through a spherical plain bearing. The palletizing and depalletizing platform 31 is driven by the traveling driving device 332 to move on the palletizing and depalletizing rack 35, so as to move the pallet on the transfer conveyor line 5 above the second conveyor line 2.
[0035] Refer to Figure 2 As shown, in this embodiment, a positioning and monitoring module 52 is arranged on the side of the second conveyor line 2 adjacent to the transfer conveyor line 5. In this embodiment, the positioning and monitoring module 52 preferably adopts a photoelectric sensor. After the pallet on the depalletizing device 3 is detected by the positioning and monitoring module 52 to reach above the second conveyor line 2, the depalletizing mechanism 33 immediately separates the stacked pallets, so as to ensure the accuracy of depalletizing.
[0036] Refer to Figure 3 and Figure 5 As shown, further, a depalletizing part is arranged on the depalletizing roller 322. The depalletizing part includes a plurality of claw hooks 324. The plurality of claw hooks 324 are arranged equidistantly along the circumferential direction on the circumferential wall of the depalletizing roller 322, and the overall shape of the claw hook 324 is an inverted "L" shape. Therefore, when the rotation driving device drives the depalletizing roller 322 to rotate, the claw hooks 324 of the depalletizing roller 322 act on the top edge of the pallet 6, separating the bottommost pallet 6 from the stacked pallets 6. The separated pallet 6 falls onto the second conveyor line 2, and the second conveyor line 2 conveys the single pallet 6 to the designated station. By repeating the above actions, the stacked pallets are separated into single pallets one by one, greatly improving the work efficiency and reducing the labor cost.
[0037] Refer to Figure 1 and Figure 2As shown, in this embodiment, a height limiting device 12 is provided on the first conveyor line 1. The height limiting device 12 includes a limiting cross beam 121 and a height monitoring module 122. The limiting cross beam 121 is erected above the first conveyor line 1. The height monitoring module 122 is a pair and is respectively arranged on both sides of the limiting cross beam 121. In this embodiment, the height monitoring module 122 preferably adopts a photoelectric sensor. When the height of the pallet stack exceeds the height between the limiting cross beam 121 and the first conveyor line 1, the pallet stack exceeding the limited height is limited by the limiting cross beam 121 so that it cannot continue to be conveyed forward. At the same time, the height monitoring module 122 detects that the pallet stack exceeds the limited height, and thus feeds this information back to the system to remind the staff and avoid the high height of the pallet stack colliding with the unstacking platform, resulting in damage to the pallet.
