Patent ID: 8763815

Claim:
A sorting table apparatus comprising: a plurality of grading rolls supported by end supports, said plurality of grading rolls arranged in parallel in succession of each other so as to form a sorting plane; a means for rotatingly driving said plurality of grading rolls in the same direction, said plurality of rolls being arranged so as to define at least one opening between adjacent grading rolls so as to allow only a pass-through and a drop-off of products to be sorted and such that objects of a size larger than the products to be sorted remain on a surface of the sorting plane and removed at a downstream end of the sorting plane; a means for modifying the opening, said end supports being mounted so as to have a limited translation on at least one lateral slide oriented perpendicularly to an axis of the grading rolls; a plurality of elastic elements interposed between said end supports; and a means for activating an approach or a distancing of said end supports and of said plurality of grading rolls supported by said end supports in opposition to a force exerted by said plurality of elastic elements so as to decrease or increase a cross-sectional area of the opening, a displacement in a direction opposite of said end supports and of said plurality of grading rolls being performed by extension or compression of said plurality of elastic elements, said means for rotatingly driving being said lateral slide.
