ABSTRACT:
A reversible drive system for a conveyor includes a belt, a drive wheel and an idler wheel, where the drive wheel and the idler wheel are mounted for rotation on spaced apart axes to define a nip between the drive wheel and the idler wheel, with the belt being pulled through the nip by the rotation of the drive wheel. Also included is a support on which the drive wheel is mounted, the support being mounted to enable a rocking motion, where rocking the support to cause the support to rotate in a first arcuate direction moves the drive wheel and the idler wheel closer to each other, thereby increasing the pinching on the belt passing through the nip. Increased tension on the belt causes rocking of the support which moves the drive wheel and the idler wheel closer to each other to increase the pinch on the belt. Rocking the support to cause the support to rotate in a second arcuate direction moves the drive wheel and the idler wheel closer to each other, thereby increasing the pinching on the belt passing through the nip, wherein increased tension on the belt causes rocking of the support which moves the drive wheel and the idler wheel closer to each other to increase the pinch on the belt.
