[0041] The working principle and process of this utility model:

[0042] First, the lateral telescopic cylinder 8 and the rear telescopic cylinder 10 extend simultaneously, driving the lateral limit plates 9 and the rear limit plates 11 to move inward. The door opening telescopic cylinder 13 then extends and pushes the front movable door 14 to rotate until it fits with the two lateral limit plates 9, thus forming a movable box structure. The grabbing conveyor 5 delivers the pallet to be carried to the bottom of the movable box structure.

[0043] The packaging bag conveyor 1 delivers the packaged packaging bags to the end position, and then the palletizing robot 3 is started, driving the box clamp 4 to move above the packaging bags, and opening and closing the telescopic cylinder 405 to open the clamp and clamp the packaging bags, and then the internal longitudinal telescopic cylinder 403 extends, driving the longitudinal pressing plate 404 to press the packaging bags to ensure stability during the grasping process. The extended clamping claw 402 can increase the stroke of the clamp to meet the requirements of palletizing, and on the other hand, increase its opening width when clamping, so that packaging bags of different widths can be clamped, which has strong applicability; the packaging bags are placed on the pallet, and multiple packaging bags are stacked in the movable box structure in sequence according to the set stacking shape;

[0044] After the whole pallet is stacked, the door telescopic cylinder 13 is retracted, driving the front movable door 14 to open outwards, and there is no obstruction in front of the pallet. At the same time, the lateral telescopic cylinder 8 and the rear telescopic cylinder 10 are retracted, driving the lateral limit plates 9 and the rear limit plates 11 to leave the surface of the stacked packaging bags. Then the bag grabbing conveyor 5 is started to convey the stacked pallet forward as a whole, completing the palletizing operation.

[0045] According to the designed stacking height, the number of movable box structures can be increased and controlled synchronously to perform stacking, which has a wide range of applications.
