PCT No. PCT/DK95/00416 Sec. 371 Date Apr. 21, 1997 Sec. 102(e) Date Apr. 21, 1997 PCT Filed Oct. 18, 1995 PCT Pub. No. WO96/12664 PCT Pub. Date May 2, 1996In sorter systems of the grader type a selective unloading or throwing out of conveyed objects is effected, from a conveyor (8) to selected receiver stations therealong. Each of these stations is equipped with a receiver bin (10) having a bottom outlet valve (22) and an upper mouthing, which, due to some spreading in the unloading function, should have a certain minimum size. In order to increase the capacity of such a system without prolonging the conveyor, the invention provides for the receiver stations to comprise more than one operative receiver bin or bin section each, which are currently switchable in a controlled manner. Preferably, use is made of a single, fixed container (10) separated in two sections with individual bottom valves, viz, separated by means of a pivot plate (18), which, with a maintained full size of the container mouthing, is pivotable against two opposed container walls for selectively guiding the received articles to the respective two sections, from which the collected article portions may be let out individually.
