Abstract

An apparatus for dispensing unpackaged articles includes a guide shaft to carry the articles, a pushing element that advances the plurality of articles along the guide shaft, and a feed screw engagable with the pushing element and driven by a motor. While the articles to be dispensed are moved collectively as a group, the apparatus provides for the controlled dispensing of individual articles. A sensor is provided to identify when an article has been dispensed and to subsequently stop movement of the plurality of articles. Also, an iris including a yieldable opening sized to allow passage therethrough of an article in a staggered manner is provided to facilitate the individual dispensing of articles and to prevent the inadvertent dispensing of articles.
