ABSTRACT:
This invention relates to an improved apparatus for orienting and aligning light weight articles, such as, empty light weight plastic bottles. The apparatus includes a hopper for receiving and holding randomly positioned light weight plastic bottles. The hopper is substantially symmetrical about a vertical center axis and includes a conical wall having a center axis coincidental with the center axis of the hopper. The conical wall has its smaller end at the bottom. An upwardly inclined track is fixed to the inside surface of the conical wall. A plurality of pusher bars is mounted within the conical wall and adapted for engagement with light weight plastic bottles on the inclined track for moving the plastic bottles upward along the track. A chute is positionable adjacent to the track for receiving a light weight plastic bottle from the track for orienting the light weight plastic bottle to a position wherein the plastic bottle is in a substantially vertical attitude. The plastic bottle leaves the chute and is delivered to a longitudinal conveyor which carries the plastic bottle away from the chute in a substantially straight line with other plastic bottles.
