Abstract
A conveyor assembly that includes a conveyor belt driven by a pinch roller drive assembly. The pinch roller drive assembly includes a pair of pinch rollers that are each rotatably mounted to a support housing. The pinch rollers are supported by a swing arm urged into a bias position by one or more bias springs. The pinch rollers and bias springs are part of a belt tension assembly mounted to the side rails of the conveyor assembly through mounting plates. The belt tension assembly can be pivoted to move the pinch rollers away from the drive roller as desired. In one embodiment, the roller drive assembly is mounted at or near the center of the conveyor assembly and can also support the drive motor. In an alternate embodiment, the pinch roller drive assembly is mounted to one end of the conveyor frame.
