Abstract
A conveying apparatus for moving articles such as pallets in a plurality of directions. The article is supported, at least partially, by a plurality of rollers mounted along parallel chains. The rollers are free to rotate, and are mounted to the chains with their axis of rotation approximately 45 degrees from the longitudinal axis of the chain. By selecting the chain to be driven, and its direction, the article can be moved longitudinally, laterally, or at approximately 45 degree angles to the longitudinal axis of the chains. The article can also be rotated clockwise or counter-clockwise in the area of the conveying system where sections of longitudinal chain terminate, and the next section of longitudinal chain starts, due to the perpendicular axis of rotation of rollers in adjacent chains.
