ABSTRACT:
A conveyor system for retaining a box thereon includes a conveyor assembly slidably adjustable on a frame. The conveyor assembly includes a first set of rollers rotationally mounted on a support rail attached to the conveyor assembly. A corresponding second set of rollers are rotationally mounted to another support rail parallel and spaced apart from the first support rail and fixedly attached to the frame. The rotational axis of each of the rollers is angled forward in the direction of operative travel of the conveyor belt and box. In operation, the angled rollers snugly engage the box and urge the box against the conveyor belt when the box is translated thereby. The distance between the two sets of rollers is adjusted by sliding adjustment of the conveyor assembly with respect to the frame, thus providing for expedited set up of the conveyor system to handle boxes of different widths. A second embodiment is presented wherein the first set of rollers is connected to at least one spring cylinder that biases the first set of rollers toward the second set of rollers.
