ABSTRACT:
An improved downstacker assembly in which paperboard blanks, received from a die cutter station, are passed sequentially through a trim removal station, a feed station, a stacker assembly partially disposed in a pit, and a stack retrieval assembly. The stacker assembly is disposed in a drop chute beneath a vacuum conveyor assembly which drops the blanks from the feed station into the drop chute, assisted by an impacting assembly which selectively separates the blanks therefrom. The stacking blanks are tamped against flexible curtains on a descending elevator assembly. A stack staging assembly serves as a temporary cradle to catch the falling blanks once a predetermined stack height is achieved until the stacks can be removed via a stack retrieval assembly.
