Abstract
An air retriever, such as a bellows (24) is used in an end effector (18) for lifting work products (22) in prearranged configurations, and delivery to a container (20) in a predetermined pattern. An air flow control valve (50) is positioned in each bellows (24) for individually controlling the flow of air through each bellows so that the bellows in a pick zone may draw air for picking up work products while air flow is not applied to the other bellows out of the pick zone.
