A 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 a pair of twin blank striker assemblies which selectively separate the blank therefrom. The stacking blanks are tamped using a semiflexible tamper plate assembly 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 the stack retrieval assembly. A dunnage holding assembly provides multiple-tier load forming as the stacks are discharged from the downstacker assembly. |
