Abstract

A conveying system includes a first continuous belt supported horizontally at two ends by a pair of rollers. A plurality of balls are mounted to the belt for rotation. A second conveyor belt is positioned within the space between the rollers defined by the upper and lower portions of the first belt such that the upper surface of the second belt contacts the balls of the first belt. As the two belts are rotated, articles may be conveyed by the first belt and rotation of the balls by the second belt causes the articles to move diagonally over the upper surface of the first belt whereupon they may be justified to one side or the other of the belt.

Claims

1. A conveying system comprising:

a first continuous belt supported at two ends by a pair of rollers, said belt defining an upwardly facing belt surface and a downwardly facing belt surface with a space therebetween;

a plurality of balls mounted to said belt for rotation; and

means positioned within said space for rotating said balls from the underside of said upwardly facing belt surface.

2. The conveying system of claim 1 wherein said means for rotating said balls includes a second continuous belt.

3. The conveying system of claim 2 wherein said first an second belts are coupled together by a gear system and driven simultaneously by a single driving member.

4. The conveying system of claim 1 wherein said rollers are provided with channels for receiving said balls when said belts pass around said rollers.

5. The conveying system of claim 2 wherein said second belt is mounted for movement in a direction transverse to said first belt.

6. The conveying system of claim 2 wherein said first and second belts are coupled together so as to be driven by a common motor.

7. The conveying system of claim 2 wherein said first and second belts are driven independently.
