Thus, when the suction cup 32 is retracted to the home position after the suction cup 32 is taken out of the package, the suction cup 32 releases the package, and the package falls onto the conveyor belt 42, and the conveyor belt 42 drives the package to be conveyed.

Downstream of the conveyor belt 42 a flattening device 5 is arranged. The flattening device 5 comprises a pressing plate 51, a first rotating shaft 52 is fixed on the bottom surface of the pressing plate 51, the first rotating shaft 52 is located above the conveyor belt 42, and the first rotating shaft 52 is rotatably connected to the frame 1. The bottom end of the pressing plate 51 is inclined to a side away from the package storage rack 2.
