the difference from the embodiment 1 is that in the embodiment 1, the palletizing conveyor and the unstacking conveyor share one traveling trolley 12 to realize the reciprocating motion of the palletizing conveyor and the unstacking conveyor in the left-right direction, in the embodiment, two traveling trolleys are provided, the palletizing conveyor is arranged on one of the two traveling trolleys, and the unstacking conveyor is arranged on the other one of the two traveling trolleys to realize the reciprocating motion of the palletizing conveyor and the unstacking conveyor in the left-right direction.

The specific embodiment of the automatic pocket stacking and unstacking machine of the invention 9:

the difference from embodiment 1 is that in embodiment 1, a first bag arresting device 11 is provided at the rear end of the pallet conveyor 6 to divert bags on the cart conveyor 13 onto the pallet conveyor 6. In this embodiment, the rear end of the stacking conveyor is not provided with the first bag blocking device, but a platform is arranged on the rear side of the cart conveyor, and the platform is provided with a pushing mechanism which pushes the material bag to the stacking conveyor after the material bag is conveyed to a position corresponding to the stacking conveyor, so as to realize the turning of the material bag. The pushing mechanism comprises an air cylinder, a pushing plate is arranged at the driving end of the air cylinder, and the pushing plate pushes the material bag when the driving end extends out.

The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, the scope of the present invention is defined by the appended claims, and all structural changes that can be made by using the contents of the description and the drawings of the present invention are intended to be embraced therein.
