ABSTRACT:
A live roll conveyor receives randomly supplied upstanding containers, such as cans, and arrests the leading cans with a pattern stop bar having pockets that arrange a transverse row of cans to receive a next assembled row of cans in nesting relation. When a backlog of alternately offset rows of cans extends upstream of an overhead clamp spaced from the pattern bar, the clamp locks two rows of containers to hold back the further upstream containers, and the pattern stop moves downstream so that one assembled charge of nested containers is moved unitarily downstream by the live rolls. A separator or retaining plate with downturned edge flanges is placed on the charge of cans, the pattern stop is further retracted to expose an underlying guide bar and allow the charge to seat against the guide bar, a gate is lowered to allow lateral discharge of the charge of cans, and a sweep arm pushes the charge to a laterally adjacent container basket of a containerized cooker. By changing the pattern bar and making certain adjustments, a different size of container can be accommodated.
