[0058] The utility model adopts automatic palletizing to replace the manual box moving and palletizing process, improves work efficiency, reduces labor input, and reduces the labor intensity of operators. At the same time, it can meet the palletizing work of various finished box specifications. The control system pre-inputs different finished box size data into the system. When changing the brand, you only need to select the brand on the human-machine interface to adapt to complete the automatic palletizing function of the cigarette pieces, and it has a buffer work area. When switching between full pallets and empty pallets, it will not affect the blockage of the front-end finished box. The structure design of the utility model is compact, innovative, easy to repair and maintain, and occupies a small area. Compared with the articulated robot, the investment is low, which reduces the investment cost. The finished product palletizing area and the auxiliary matching tray and handling area have been planned in the system to reduce the overlap of the cross-operation areas of the two process operations, thereby improving the work efficiency of the finished product box palletizing.
