Abstract
A curve unit for live roller line shaft conveyor systems is described. In a preferred embodiment, the curve unit includes a curve segment with driven rollers powered by a drive disc and a pair of straight segments with driven rollers powered by a pair of drive shafts through the use of elastomeric belts. The unit may be incorporated in a live roller, line shaft conveyor system with all of the driven rollers powered by a single drive motor. Alternatively, the curve unit may be driven by a dedicated drive motor. An annular lip is provided on the disc drive to frictionally engage the bottom surfaces of the conveyor rollers in the curve segment so that rotation of the drive disc about its vertical axis also drives the rollers in the curve segment. The described arrangement of parts provides for synchronous rotation of driven rollers in both the curved segment and the adjoining segments of the curve unit as well as the driven rollers in the conveyor system.
