  • Patent number: 6047527
    Abstract: A bag loading apparatus (26) of a packaging system (10) includes a platen (68) having a convex upper surface upon which layers of bags (16) are sequentially placed, with the platen (68) being lowered upon receipt of each layer, until a full stack is supported on the platen (68). The loading apparatus (26) also includes a pivotally mounted pusher plate (98) against which the layered bags (16) are arranged when supported on the platen (68). Furthermore, a shelf (58) is arranged above both the platen (68) and the pusher plate (98) and is preferably pivotally mounted about a common axis with the pusher plate (98). With a stack of bags (16) on the platen (68), the pusher plate (98) accelerates across the platen (68) to shift the bags (16) into an open container (28), with the bags (16) preferably assuming a generally wedge-shape to aid in the loading of the bags (16) into the container (28).
