The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] See also Figure 1-Figure 3 The present embodiment provides a pallet depalletizing and stacking device, including a driving module 10. The driving module 10 includes a driving motor. The output end of the driving motor is connected to two groups of conveyor belts or chains through structures such as synchronous belts and gears. In the present embodiment, a conveyor belt 11 is used. The two groups of conveyor belts 11 are supported and fixed by a support frame. A support rod with an adjustable length is provided between the two groups of support frames so that there is a certain interval between the two groups of conveyor belts. The interval distance is set according to the size of the pallet and can be sufficient to drive the pallet to move. A depalletizing mechanism 12 and a stacking mechanism 13 are respectively provided at the starting end and the end end of the conveyor belt. The depalletizing mechanism 12 and the stacking mechanism 13 have the same structure. The present embodiment uses the depalletizing mechanism 12 as an example for explanation. The depalletizing mechanism 12 includes four groups of vertical plates 121. Two groups are respectively provided side by side on one side of each conveyor belt. A storage space is formed between the four groups of vertical plates 121 for placing pallets. At the same time, a protective plate 122 is provided on each vertical plate for enclosing the pallet.

[0022] In order to facilitate the stacking and placement of pallets, two sets of protective plates 122 near the starting end of the conveyor belt are rotatably connected to the vertical plate 121 through a hinge. When a pallet needs to be placed, the protective plates 122 are opened, and the protective plates can be closed after placement. At the same time, handles 120 are provided on the above two sets of protective plates 122 for easy opening and closing.

[0023] Since the above two sets of protective plates 122 are in an open and closed state, magnets are respectively provided at corresponding positions on the protective plates 122 and the vertical plates 121. When the protective plates are closed, the magnets are attracted to ensure that the protective plates will not be easily opened, thereby ensuring a smooth destacking process of the pallets.

[0024] A lifting assembly 14 is arranged below the two groups of conveyor belts. The lifting assembly includes a lifting motor 141. The lifting motor 141 is connected to the bottom end of the vertical plate 121 through a mounting plate 142. A screw rod 143 is arranged at the output end of the lifting motor 141. A movable plate 144 is arranged on the screw rod 143. Two groups of guide rods 145 are arranged on the movable plate 144. The top end of the guide rod 145 can move through the mounting plate 142 and is connected to a lifting plate 146. The lifting plate 146 can extend from between the two groups of conveyor belts to the top of the conveyor belts for lifting the pallet.

[0025] In order to locate the height position of the lifting plate 146, a positioning plate 147 is set on the movable plate 144, and a U-shaped switch 148 is respectively set on the lifting motor 141 below and the mounting plate 142 above. When the movable plate 144 moves up and down, the positioning plate 147 stops when it passes the detection position of the U-shaped switch.

[0026] A horizontal plate 123 is arranged between the two groups of vertical plates 121 above each conveyor belt, a supporting cylinder 124 is arranged on the horizontal plate 123, a vertical supporting plate 125 is arranged at the output end of the supporting cylinder 124, two groups of horizontal supporting plates 126 are arranged on the vertical supporting plate 125 at intervals, a linear bearing 127 is arranged on the horizontal plate 123, two groups of guide columns 128 are arranged between the vertical supporting plate 125 and the linear bearing 126, the horizontal support plate 126 is used to support the pallet, and the vertical support plate 125 is used to enclose the pallet from the side.

[0027] A lifting cylinder 15 is arranged under the conveyor belt between the depalletizing mechanism 12 and the stacking mechanism 13, and a lifting plate is arranged at the output end of the lifting cylinder 15. The lifting plate can also be extended upward from between the two sets of conveyor belts to lift the pallet when the pallet moves to the middle position of the conveyor belt.

[0028] It should be noted that each pallet 16 is provided with a rib 161 so that there is a gap between two adjacent pallets when stacking. Multiple layers of pallets are stacked on the destacking mechanism 12, and the bottom is supported by the horizontal support plate 126. When destacking, the lifting motor 141 is started, driving the lifting plate 146 to rise and support the bottom end of the pallet, the support cylinder 124 drives the support plate to retract, and the lifting motor drives the pallet to drop one layer. The horizontal support plate 126 is extended to support the bottom of the second to last pallet below. Then the lifting motor places the bottom pallet on the conveyor belt 11, and then the conveyor belt moves the pallet to the middle position and stops. The lifting cylinder 15 drives the lifting plate to lift the pallet for stacking. After completion, the pallet is put down, and the conveyor belt moves the pallet to the position of the stacking mechanism 13, and stacking is performed using the same principle as the destacking mechanism 12. The action sequence is basically the opposite of the destacking mechanism.

[0029] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
