Abstract: An accumulator for storing rows of articles thereon includes a frame having upper and lower shafts rotatably supported thereon. A plurality of sprockets are mounted on each of the upper and lower shafts for rotation therewith. Each of the sprockets defines a radius. An electric motor is provided for selectively rotating the shafts and the sprockets mounted thereon. A plurality of roller chains are mounted on associated pairs of the upper and lower sprockets for movement when the shafts and sprockets are rotated. Each of the roller chains includes a plurality of spaced apart pins. A plurality of link are carried on each of the roller chains for movement therewith. Each of the links has a pair of apertures formed therethrough and a pair of arcuate slots formed therethrough. The apertures and the slots having respective first edges which define a straight line and respective second edges which define a radius.

Abstract: A guide system for packages on a conveyor system includes a generally linear guide member. The guide member aligns the packages as they move along the conveyor system. A generally linear control member is connected to the guide member and lies generally parallel thereto. The control member can be rotated around its longitudinal axis to move the guide member in a generally arcuate path. This causes adjustment of the guide member to accommodate different sizes of packages.

Abstract: A drive system for a curved, live roller conveyor comprised of two groups of rollers is disclosed. The drive system includes separate drives, one for each group of rollers and a common power source for rotatably driving each of the separate drives. Each roller group drive includes a pair of parallel arranged drive shafts which drive corresponding individual rollers through an elastomeric belt entrained about pulleys affixed to the drive shaft and the rollers.
