Abstract
Abstract High speed feeding, counting, orienting and storing of small parts such as ammunition, candy, pills, machine screws, nuts, miniature containers and the like. The articles are radially distributed upon a rotating planar surface having an axis; the articles are then advanced upon a plurality of peripherally spaced spindles or rollers which extend radially outwardly from the axis. The articles are then discharged from the spindles. The spindles may be of the idler or power driven type enabling the sorting of heavy parts. For example, the spindles may be rotated at a speed proportional to the rotational speed of the inner axis, such that the high surface speed of the individual rollers will enhance discharge, alternatively, the rollers may be rotated at a speed lower than the rotational speed of the inner axis which will enhance radial distribution prior to discharge.
