ABSTRACT:
A sorting apparatus classifies and discharges articles, such as items of agricultural produce, in accordance with their individual weights. A multichannel conveyor cooperates with a front end singulator which receives the produce from a source of supply and which provides the items in single file to a continuous line of spaced carrying cups moved by the conveyor along each channel. The cups are disposed for movement between an upright article carrying position and a depending discharge position, and they are supported by a rail in each channel. The rail has openings therein at each of a plurality of discharge stations spaced therealong. The cups each pass over a weighing scale aligned with the supporting rail near the front end of each conveyor channel which scale comprises a pivotally mounted bar upon which the cups ride. The bar provides a weight signal when it pivots with the signal determining the position of the cup on the bar when pivoting occurs and thereby being proportional to the weight of the cup and article supported thereby. A fast acting gate is located in each channel at each discharge station. The gate is configured to be either actuated to a discharge position away from the opening, thereby allowing a cup to assume the depending discharge position, or unactuated to thereby bridge the opening and allow the cup to pass and remain in its upright article carrying position.
