Abstract
An accumulating conveyor includes a frame having generally parallel sides with a plurality of load-carrying rollers rotatably mounted between the frame sides. A plurality of lifting rollers are rotatably mounted between the frame sides beneath the load-carrying rollers. A drive belt extends between the load-carrying rollers and the lifting rollers for rotating the load-carrying rollers in response to the lifting rollers lifting the belt into engagement with the load-carrying rollers. A plurality of sensing roller assemblies are mounted on selected, spaced load-carrying rollers. The sensing roller assemblies each include a carriage pivotally mounted on the axis of a load-carrying roller, a sensing roller mounted on the carriage on one side of the axis and a counterbalance roller heavier than the sensing roller mounted on the opposite side of the axis. The counterbalance roller is effective to bias the sensing roller into the path of movement of articles moving along the conveyor. The sensing roller assembly is operatively associated with actuator means for deactivating the drive to load-carrying rollers upstream of the sensing roller assembly when an article depresses the sensing roller.
