ABSTRACT:
A sorting apparatus for sorting items according to weight or other measurable characteristics. An elongated conveyor feeds the items to be sorted to a combined weighing and conveying mechanism, which after weighing the item, is driven in one direction or another to drop the item weighed onto a uni-directionally driven conveyor. The unidirectionally driven conveyor transports the item it receives and deposits it onto a bi-directionally driven conveyor. The bi-directionally driven conveyor is then driven in the necessary direction to transport the item it receives and to deposit it onto a selected bi-directionally driven conveyor. This bi-directionally driven conveyor, in turn, is selectively driven to cause the item it receives to be deposited into the indicated receiver for items of weight corresponding thereto. Thus, any items deposited onto the combined weighing and conveying mechanism will automatically be transported to the appropriate receiver in accordance with the weight of the items detected by the weighing mechanism. In an alternative embodiment, the bi-directionally driven conveyor is replaced with a bi-directionally driven weigh block. This block is generally square with four concave surfaces and is adapted to receive items from the supply conveyors and to weigh those items and to cause the weigh block to rotate ninety degrees in either one direction or the other depending on the weight of the item, deposits the item weighed onto the appropriate conveyor.
