ABSTRACT:
A conveyor assembly having a spring loaded belt tension roller mounted in slots on the sides of the frame to provide automatic adjustment of an endless belt to maintain optimum tautness. The frame has a relatively low profile with the belt guided by the vertical side rails of the frame in the forward and reverse directions to prevent lateral shifting of the belt, with the side rails connected by coupling bars. The drive roller is mounted on a single roller bearing with the inner race secured to a bolt which is fitted to a keyed hole on the side of the frame with the other end of the drive roller directly coupled to a drive motor. An idler roller mounted in close proximity to the drive roller provides contact of the belt with a substantial portion of the circumference of the drive roller to increase the frictional drive between the drive roller and the conveyor belt. A slide surface on the top of the frame is removable to provide access to the tension roller, drive roller, and idler roller for purposes of threading the tension roller and ease of maintenance of all the rollers.
