Abstract
A system for cleaning, rinsing, coating and drying cans having a circular side wall and a closed end wall at a high rate of speed as the cans emerge from the apparatus by which they are formed. The system basically comprises a washing stage, at least one rinsing stage and a drying stage, with one or more coating stages provided if desired. Each stage is housed in its respective housing and having a can entrance location and a can exit location, with the exit location of one stage being connected to the entrance location of the next succeeding stage by conveyor means. The stages are of a generally similar construction and basically comprise a carrier assembly disposed within the housing for receipt of the formed cans. The carrier rotates about a main longitudinal axis for carrying the cans from the entrance location to the exit location through a circular orbit and in planetary motion, wherein the cans are rotated about their own longitudinal axis as they orbit about the main longitudinal axis of the housing. Reciprocating spray means are provided to reciprocate into and out of the cans as they orbit to spray the interior of the cans while stationary spray means disposed adjacent to…
