Abstract: Apparatus for sorting articles having a roller conveyor for moving articles through an inspection region where they are scanned by a camera. From the scans, the position of boundaries of the articles is determined so that the existence and location of the articles can be identified. Color counts, representative of the color of the articles are made from the scans and are correlated with the appropriate article identified. Load cells produce weight information which is similarly correlated with the appropriate articles. The information is fed to a processor which is arranged to track the articles through the inspection region and is arranged to route the articles differently in accordance with the color counts and/or weight information correlated therewith.

Abstract: Apparatus for transporting articles (32) includes a plurality of spaced, substantially parallel axles (4) coupled for movement by an endless chain drive. Each axle (4) extends substantially transversely to the direction of movement and has a number of carriages (2) coupled thereto. The carriages (2) are spaced along, and pivotably mounted on the respective axle (4). Each carriage (2) has a skid member (10) supporting two pairs of wheels, the first pair of wheels being carried by the respective axle (4). The articles are supported on the wheels (6,8) as the carriages are pulled along on their skid members (10) over an appropriate support. If it is required to inspect the articles, the wheels are brought into contact with elongate support members (20, 22) so that they are rotated and thereby rotate the article carried thereby. Deposit of an article is achieved by removing support from the respective carriages (2) so that the carriage pivots relative to said axle (4).

Abstract: The invention is a device for sorting food products such as vegetables or fruit in accordance with their size, weight, and color or the presence of defects on them. In accordance with the device of the invention, a conveyor in the form of a plurality of rotatable rollers is employed for supporting the articles to be inspected and sorted. The articles are passed through an inspection zone where the articles are scanned in accordance with the sorting criteria of the apparatus. The articles are then sorted in accordance with in response to the determinations made at the inspection zone.

Abstract: A method and apparatus for cutting dark portions such as blemishes from articles such as potato stick. In order to detect the blemishes the articles are conveyed through an inspection station by a conveyor having a plurality of rollers arranged perpendicular to the direction of conveyor. The rollers are rotated thereby rotating the articles as they are conveyed through the inspection station so that each side of the articles may be inspected. The inspection station utilizes a raster scan television camera and output signals therefrom are used to actuate one of a plurality of cutting devices in order to sever from the articles those portions containing blemishes. The severed portions containing blemishes are thereafter separated from the remainder of the articles by either a screen or by air jets.
