ABSTRACT:
The present invention is an apparatus for segregating desired parts of predetermined dimension from a jumbled flow of such parts and by-product runners. The apparatus includes structure that defines a path for restricting the jumbled flow to a fixed-flow space along a flow length. The apparatus comprises a three-dimensional array of rotatable pickup fingers substantially filling the fixed-flow space and extending therebeyond. The apparatus further includes a suitable device for continuously moving successive distal portions of the rotatable finger array out of and into the fixed-flow space. The rotatable fingers are spaced apart by distances greater than the predetermined dimensions of the desired parts but less than the longest dimension of the runners, for capturing the runners while allowing the desired parts to pass through the pick-finger array. The apparatus additionally comprises stationary fingers, positioned to intermesh with the rotatable finger array, for causing the desired parts to become separated from the by-product runners. The apparatus further includes additional structure so located and configured as to remove the runners from the rotating fingers during rotation of the finger array and allow the thus-removed runners to be conveyed under the influence of gravity away from the apparatus.
