Abstract:
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.

Abstract:
A vertical uncoiling apparatus having a frame assembly for supporting a coil of strip material and an accumulator assembly for selectively removing and delivering the strip material to downstream processing equipment. The accumulator assembly is provided with an accumulation loop area defining a substantially S-shaped travel path for the strip material and a feed assembly for removing strip material from the coil of strip material and feed same into the accumulation loop area so that a steady state flow of substantially tension-free strip material can be delivered to downstream processing equipment.

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.
