Abstract

Successive pairs of rollers in a plurality of juxtaposed continuous feed chain conveyors receive articles, such as fruits and vegetables at an upstream portion of a sorting conveyor system and by movement of the rollers between inclined walls, position the articles in succession so as to pass the same through color sortors and, then, below pneumatic rollers to deposit them into successive cups of a sorting conveyor system. Excess articles on the feed conveyors are released near the downstream end of the feed conveyors and are returned to their upstream end for reprocessing. Adjustable synchronizing linkage tie the two systems together and permit the relative adjustment of the positions of the cups with respect to the positions of the rollers. Spinning of the rollers is accomplished by the rollers riding in the through assemblies for the upper flights of the feed conveyors. Rails lift the rollers when they are not to spin. The color sortor examines the articles as they are spun by the rollers. The cups form a part of a soring conveyor system for dropping the articles according to prescribed color and/or weight.
