Abstract
This invention relates to a roller assembly for a power free triple conveyor having an overload release device which includes a sprocket mounted on a shaft through a bearing, a roller separately formed and freely rotated on the sprocket, a plurality of springs resiliently installed within the holes of the roller, a pair of friction plates and snap ring located adjacent to the roller, and a guide rail fixed at the upper portion of the frame. The conveyor can reduce noise and vibration between the drive members in an un-manned robot environment, and transport products quickly and accurately.
