Abstract

Apparatus for collecting and storing empty aluminum containers for recycling. The containers are inserted into a chute having a regulating feed mechanism. The cans fall out of this one-by-one into a crushing zone between a reciprocating ram and a stationary platen, and interrupt a sensor beam which initiates the crushing cycle of the ram. After crushing, the cans drop into a container past the outer end of a can stop. The stop is counterbalanced so that empty cans will be retained in the crushing zone for flattening, while partially full containers displace this and fall through. The drive mechanism for the ram is provided by a compound eccentric cam having thrust and retraction faces, and first and second roller followers for engaging these. Preferably, the assembly is mounted in a cabinet for inclusion in a stand of vending machines.
