ABSTRACT:
A conveyor system of a type having a first pulley disposed for rotation about a first axis and a second pulley disposed for rotation about a second axis substantially parallel to the first axis. The continuous conveyor belt is disposed around the first and second pulleys. The first idler roller rotatably disposed along a third axis is substantially parallel to the first axis and parallel to the first axis is provided for supporting the weight of a conveyor belt and the materials moving thereon, said third axis being fixed with respect to the first axis. A second idler roller is disposed along a fourth axis, the fourth axis being substantially parallel to the first axis. The second roller is disposed below a bottom portion of the fixed axis conveyor belt for supporting the weight of the conveyor belt. An encoder is disposed on the stationary shaft inside one of the idler rollers for monitoring rotation of the idler rollers with respect to the shaft.
