ABSTRACT:
The present invention is an apparatus for segregating desired articles of predetermined dimensions from a jumbled flow of such articles and unwanted pieces longer than the predetermined dimensions. The apparatus includes structure, tilted relative to the horizontal, that restricts the jumbled flow to a fixed-flow space whereby the jumbled flow is caused to flow along a flow path. The apparatus comprises a three-dimensional array of rotatable pickup fingers substantially filling the fixed-flow space and extending therebeyond. The apparatus includes a biasing element that co-acts with the rotatable pickup fingers to retain an unwanted piece removed from the jumbled flow by the pickup fingers. The apparatus further includes a suitable drive mechanism for continuously moving successive distal portions of the rotatable finger array out of and into the fixed-flow space, for bringing the unwanted pieces into biasing engagement with the biasing element, and for causing the thus-engaged unwanted pieces to be removed from the fixed-flow space.
