Abstract: A singulator apparatus and system for use with a product conveying and/or sorting system to place products in a single layer line of such products that are also separated from each other so the products may be more effectively and efficiently sized, inspected, sorted or otherwise processed in the processing area of the conveying and/or sorting system. The singulator apparatus has at least one pair, preferably a plurality, of adjacent cylindrical assemblies that are linearly aligned to be parallel with each other and define a valley between the adjacent cylindrical assemblies. Jumbled products are directed to the valleys from a product transfer area that receives the products. The cylindrical assemblies each have a cylindrical member and a shaft, with the shaft connected to a rotating mechanism that rotates the cylindrical assemblies to singulate and separate the products as they move along the valley between cylindrical assemblies.

Abstract: An apparatus and method for inspecting and sorting articles such as fruit and vegetables in which the articles are presented, on a conveyor, under a viewing device and classified. A take-off position is determined from the classification and the article is removed by means of an independently actuated ejector mechanism.

Abstract: A roller element for a roller assembly used in an endless conveyor system for grading/sorting articles. The roller element has a faceted peripheral edge, each facet being of equal length, with approximately 12 facets per unit. Also, a quick-release roller assembly for use in a similar endless conveyor system includes a steel shaft on which roller elements are mounted. The shaft has a first opening in one end to receive a connecting pin element from a first chain and a second opening in the other end thereof which receives a connecting pin element from a second chain. Bushings are positioned in both of the shaft openings for receiving the connecting pin elements. In the one opening, a spring element is positioned between the bushing and the bottom end of the opening. The shaft has a slot in the side surface of the shaft, opening onto the first end of the shaft.
