Abstract: A conveyor system includes an accumulation conveyor that is particularly useful in a location outbound of a sortation spur in combination with a receiving conveyor which receives products from the accumulation conveyor at a generally constant rate. The accumulation conveyor includes a plurality of powered rollers that are selectively actuatable in groups of tandemly arranged zones in order to convey product to the receiving conveyor. A product sensor associated with each zone senses the presence of product in that zone, and a control that is responsive to the product sensor actuates all of the rollers associated with zones upstream of any sensor that is not sensing product in order to transport product to the receiving conveyor without singulation, yet provide an accumulation capability.

Abstract: A flowsplitting conveyor device for controlling a load imposed on a conveyor utilizes a load allocating device which is capable of dividing a incoming load between two receiving conveyors for the purpose of balancing the load between the two receiving conveyors or it can be used to allocate the entire load to either one of the receiving conveyors.

Abstract: The specification discloses a split-cam conveyor roller assembly including a pair of eccentric rollers rotatable relative one another between transportation and accumulation positions. A pin fixed in one roller is received within a circumferential slot in the other roller. A magnet is fixed at one end of the slot, and the pin is made of a ferrous material to aid in retaining the rollers in the transportation position.

Abstract: The operating characteristics of a diverter having a driven article conveying surface of parallel tubes on which article diverting shoes are caused to move across progressively because of contract between a depending drive pin on each shoe and a laterally inclined rail beneath the conveying surface by changing the shape of the rail contacting roller on the pin so that a downward force vector is created tending to hold the shoe down. Also, the shoe is supported on three rollers instead of two to prevent the tendency of the shoe to pivot about one tube due to article resistance to lateral movement. The design of the openings in the shoe through which the tubes pass are such that the shoe will not become bound between two tubes which are not entirely straight.
