ABSTRACT:
A block sorting system includes a block transferring apparatus that has a plurality of independently movable opposing pairs of gripping members. The gripping members pick up the row of blocks on a staging conveyor and move the row of blocks laterally to a set of adjacent sorting conveyors. A sensor apparatus measures the length and width of each block in the row of blocks while the row of blocks is laterally translated to the sorting conveyors. The independently controlled gripping members release a first set of blocks having a first length and width onto a first sorting conveyor. The remaining blocks are translated over a second sorting conveyor and a second set of blocks having a second length and width are released onto the second sorting conveyor. Rejected blocks may be translated laterally to a container and released into the container.
