Abstract

See full text

A device for handling stacking or removing articles from a stack, has a stacking wheel located between the lifting elements for stacks and a conveyor. When the stacking wheel turns, depending on the direction of its rotation, an article is moved from the conveyor onto the stack in the lifting direction. The stacking wheel bears pairs of holding plates distributed around its periphery; on them swivelling fingers are supported. The swivelling fingers are pressed by springs into their action position in which they project over the facing surfaces of the holding plates and fit into receiving openings of the articles when articles are moved by the stacking wheel. Control plates are assigned to the stacking wheel and engage with their ramp edges the concave, downwardly pointing surface of the swivelling fingers to swivel them into their readiness position which does not project to the inside over the holding plates.
