System and method for zero defect carton rejection

Abstract

A post compression carton rejection system for receiving cartons in-line from a carton assembly system having a compression conveying section for compressing folded and glued cartons for delivery to a packing system. The post compression carton rejection system comprise a frame adapted to be supported between the compression conveying section and the packing system. An infeed conveyor is mounted to the frame and has an infeed belt for transporting folded and glued cartons from the compression conveying section and an infeed drive for driving the infeed belt. An outfeed conveyor is mounted to the frame between the infeed conveyor and a conveyor exit proximate the packer, in use, and comprises a nose extension conveyor having an outfeed belt including a dump gate controllably retractable at the conveyor exit to selectively dump folded and glued cartons, an outfeed drive for driving the outfeed belt and a dump gate actuator for opening and returning the dump gate. A controller operatively controls the infeed drive, the outfeed drive and the dump gate actuator to selectively create gaps before and after a stream of defective folded and glued cartons and dump the defective folded and glued cartons at the dump gate.
