Title: Zero back pressure conveyor system

Abstract: A zero back-pressure conveyor system of the type having a continuous transport element for urging articles along a predetermined conveyor path employs a frame that supports the continuous transport element and is formed of first and second side on opposite sides of the continuous transport element. Articles being transported along the conveyor system are supported on wear strips that are fashioned as segments along the conveyor path and are each individually actuatable between distal and proximal positions with respect to the continuous transport element. Preferably, the wear strips are actuated in pairs by operation of an articulated mechanism that precludes tilting of the articles during coupling and decoupling with respect to the continuous transport element. The articulated motion is achieved by operation of a support bar coupled to the associated wear strip, the support bar having at least one pair of pivotally coupled coupling arms. A linear actuator urges the coupling arms to rotate about their respective pivot points. Bar couplers are disposed across the conveyor to insure that pairs of wear strips operate simultaneously to prevent tilting of the articles either longitudinally or transversely with respect to the conveyor path.
