ABSTRACT:
An apparatus is disclosed for automatically stacking and progressively accumulating a plurality of identical articles so that they can be loaded as a unit into a shipping container. The apparatus comprises a pair of indexing chains guided in low-friction tracks on a descending angle and driven by sprockets which are indexed periodically by a rotary drive. A series of trays is supported between the chains, each tray being sized to accommodate a full case load of product. The descending angle of the chains is such that the trays on the upper side of the chains are always arranged horizontally to form descending accumulation stations at levels that are spaced apart by a distance equal to the height of the product. Infeed conveyor belts are located on one or both sides of the accumulation stations for bringing in the articles to be stacked, and a lateral, horizontally directed actuator is provided to transfer them from the conveyor belts to the trays. At the lower end of the chains, each fully accumulated unit of articles is transferred laterally by another actuator to a platform, such as an elevator, for loading into a shipping container.
