When one material dividing part 6 is matched with the stacking device 3 for unloading operation, the other material dividing part 6 can be matched with the package issuing device 1 for feeding operation; the stacking device 3 can be moved to the designated drop position driven by the stacking adjustment device 8. Specifically, the head used for unloading on the market is often fixed to the gantry 12, but when the truck is parked, there is often a certain amount of offset, which is prone to inaccurate drop when stacking, and it is easy to fall to the side of the carriage or outside the carriage.
