ABSTRACT:
An apparatus according to the present invention comprises a lift mechanism provided at the end of an introducing-aligning conveyor mechanism and a shutter mechanism overlying the lift mechanism. A plurality of cases are arranged in alignment on the conveyor mechanism. The cases are pushed up by the lift mechanism and supported by the shutter mechanism. When cases of another set are then aligned on the introducing-aligning conveyor mechanism, the shutter mechanism opens, so that the cases supported thereon fall to be stacked on the second set. The stacked cases are pushed up by the lift mechanism and supported by the shutter mechanism. These processes of operation are repeated so that the cases are stacked in layers.
