<p>A feed-in can conveyor receives a bank of multiple rows of cans from a first work station, such as a can washing apparatus, and conveys them in inverted position, that is, with the open ends of the cans facing down and the closed bottom ends facing up, under a perforated endless can-carrying and can-uprighting conveyor belt which works over the peripheral surface of a rotary foraminous metal cylinder or drum. Vacuum is applied from a vacuum chamber or housing, and a first vacuum control device, to the perforated endless conveyor belt which lifts the cans off the feed-in can conveyor belt and the perforated endless conveyor belt "grabs" and holds the cans as they are carried by the perforated endless can-carrying and can-uprighting conveyor belt, with the closed bottoms of the cans disposed against the perforated endless conveyor belt, around approximately half of the peripheral surface or circumference of an air-permeable rotary foraminous metal drum or cylinder until they reach the top of the drum of cylinder where the vacuum from the vacuum chamber or housing, acting through a second and upper vacuum control device and the perforated endless conveyor belt, is cut off and the cans are delivered in upright position to a take-away or delivery conveyor by which they may be transported to a second work station, such as a printing and labeling apparatus, or the like.</p> |
