Abstract

Abstract A conveyor system (28-30) includes a track (110) and a conveyor chain (70) for movement along the track. The conveyor chain comprises a plurality of identical links (72) each including a first connection member (74), spaced, parallel, longitudinally extending plates (76) and a second connection member (78). The plates are connected to the connection members for pivotal movement about vertical axes, and the connection member of adjacent links are connected to each other for pivotal movement about horizontal axes thereby accommodating horizontal and vertical flexure of the conveyor chain. The conveyor chain (70) is actuated by a drive mechanism (180) including a drive chain (198) and chain engaging members (206) carried thereby which engage the conveyor chain along an arc having a substantial radius, thereby propelling the conveyor chain through the track (110) without subjecting the conveyor chain to periods of high acceleration.
