ABSTRACT:
The disclosure describes an improved apparatus for orienting and feeding light weight articles, such as, empty plastic bottles. The apparatus includes a hopper for receiving and holding randomly positioned articles. A rotatable drum has a portion portioned below the hopper for receiving articles from the hopper. The drum has its axis of rotation offset from the vertical and rotates about its axis of rotation. A stationary shelf is positioned adjacent to the drum. A longitudinal conveyor is positioned adjacent to the drum for receiving articles from the drum. The improvement includes a plurality of removable chutes defining a portion of the drum. Each of the chutes intermittently communicates with the hopper for receiving articles of a given size from the hopper. The stationary shelf cooperates with each of the chutes for retaining articles in each of the chutes for a prescribed arc of rotation of the drum. A lock releasably holds the chutes in a selected position relative to the hopper. Release of the lock allows the chutes to be quickly removed and replaced by chutes of another size to handle articles of another size. The number of chutes of each size can be quickly varied to effect maximum efficiency of each of several different sizes of chutes.
