BELT CONVEYORS WITH RETRACTABLE WALL SEGMENTS

摘要

A conveyor having a conveyor belt with wall segments that pivot between a retracted position below the conveying surface of the belt and an extended position above the conveying surface. When extended, the wall segments form a wall along the length of a portion of the belt to prevent conveyed articles from moving laterally past. The retractable wall segments are cam- or spring-actuated. Diverting conveyors using the retractable wall segments in an oblique-roller conveyor belt are useful as sorters or switches.
