Abstract
Apparatus for forming a package containing rows of stacked articles includes a bottom loaded spiral stacker for successively elevating individual articles to be packed, an article conveyor for feeding successive articles to the stacker, a stacking conveyor above the stacker for accumulating stacks of articles formed by the stacker and moving the stacks away from the stacker, a separator conveyor which moves in parallel relation with the stacker conveyor and receives U-shaped separators or partitions, a first transfer mechanism for moving each successive formed stack from the stacking conveyor to the separator conveyor, and a second transfer mechanism for moving successive rows of stacked articles from the separator conveyor to a carton set-up station. The spiral stacker operates in timed relation with the stacking conveyor which operates intermittently to move each successive stack formed by the spiral stacker in a direction away from the spiral stacker.
