The first transverse member 31 drives the product stacking mechanism 4 to achieve horizontal movement in a first direction. The product stacking mechanism 4 includes a second transverse drive 41 disposed on the transverse plate 32. The output end of the second transverse drive 41 is equipped with a second lifting drive 42, and the output end of the second lifting drive 42 is equipped with a product clamping member 43.

[0044] Working principle:

[0045] The pallet truck loaded with empty trays is placed in the first accommodating area 101 , and the empty pallet truck is placed in the second accommodating area 102 .

[0046] The first lifting member 22 in the first accommodating area 101 moves, driving the first material dividing member 23 to descend, clamping the top empty material tray, and the first lifting member 22 drives the empty material tray to rise above the material tray support member 24. The second telescopic cylinder 241 extends, driving the supporting plate 242 to be placed under the empty material tray, and the first material dividing member 23 releases the empty material tray and places it on the supporting plate 242, thereby realizing automatic separation of the empty material trays.

[0047] The product clamping member 43 clamps the product to be unloaded from the processing equipment at the front end, and the first transverse member 31, the second transverse drive member 41 and the second lifting drive member 42 are activated to move the product clamping member 43 to the top of the stacking position of the material tray, and the rotating cylinder 432 and the second rotating drive member are activated to adjust the angle of the pneumatic clamp 435. The placement angle can be adjusted in various ways according to the clamping state of the product, and it is highly flexible.

[0048] After the tray is full of materials, the tray clamping member 33 descends to clamp the tray, and the first transverse member 31 drives the tray clamping member 33 to move horizontally above the second accommodating area 102. The first material dividing member 23 in the second accommodating area 102 clamps the tray, and the tray clamping member 33 releases the tray. The corresponding first lifting member 22 in the second accommodating area 102 drives the first material dividing member 23 to descend, and places the full tray on the palletizer 5, thereby realizing automatic stacking of the full tray.
