Abstract
Abstract An apparatus and method are described for packing a plurality of containers in a case at a packing station. The apparatus comprises a plurality of suction cups mounted on vacuum manifolds suspended between two flexible endless transporting chains which are laterally spaced from one another. Containers are deposited on the vacuum cups and a vacuum is applied to the manifolds. The transporting chains are then driven to invert the suction cups and gripped containers. The vacuum is then disabled and the containers are left in cartons located below the transporting chains. Once a vacuum is applied to the manifolds, the transporting chains are driven in response to a drop in pressure in the manifolds so that as soon as all containers are gripped by the suction cups, the pressure drops and the chains are driven. A product retainer which controls the flow of containers to the packing station comprises solenoid-actuated clamping surfaces on both sides of a dead plate and flexible portions of lane dividers separating lanes of conveyed articles. To stop the flow of containers in all lanes, the clamping surfaces press inwardly on containers in outside lanes, and this inward pressure is transmitted across all the lanes via the flexible lane-divider portions.
