POWERED CONVEYOR BELT TURN

摘要

A powered belt turn (10) for conveying parcels, objects and the like through an arcuate path from an input conveyor (11) to an output conveyor (13). The powered belt turn (10) comprises a frustoconically shaped conveyor belt (15) which is supported for rotation through an arcuate path about angularly displaced end rollers (56). The conveyor belt (15) is selectively and preferentially stiffened by reinforcing stays (40) adapted to the conveyor belt structure. A motor (74) is operatively attached to an end roller causin g the end roller (56) to rotate thereby rotating the conveyor belt (15). The conveyor belt (15) is supported on a belt support plate (28) and maintained in engagement with the end rollers by a belt retainer (12). In a first embodiment, the belt retainer is a sheave belt retainer (12) comprising sheaves (96, 98) adapted to engage an inner edge (36) of the conveyor belt (15) and to urge the conveyor belt (15) into engagement with the end rollers (56).
