Compact article singulation conveyor
First Claim
1. An article singulation conveyor, comprising:
- a receiving portion to which articles are delivered in random order including clusters of side-by-side articles and a discharge portion from which articles are discharged in a single file singulated stream;
a first conveying surface defined by a plurality of generally laterally extending powered rollers that is adapted to transport articles longitudinally from said receiving portion to said discharge portion;
a recirculation bed which removes side-by-side articles from a downstream portion of the first conveying surface to an upstream portion of the first conveying surface, wherein clusters of articles tend to recirculate around said recirculation bed and said first conveying surface as individual articles of the cluster are pulled away along said first conveying surface;
a take-away conveyor at said discharge portion comprising a flow controller controlling relative speed of articles as the articles move in a same direction from said discharged portion.

Abstract
A compact article singulation conveyor includes a receiving portion which receives articles in random order including clusters of side-by-side articles and a discharge portion from which articles are discharged in a single file singulated stream. A first conveying surface transports articles longitudinally from the receiving portion to the discharge portion. A recirculating bed removes side-by-side articles from a downstream portion of the first conveying surface to an upstream portion of the first conveying surface. The recirculating bed may be made up of at least one peel-away conveyor having a second conveying surface adapted to move side-by-side articles laterally off the first conveying surface, at least one coupling conveyor having a third conveying surface adapted to move articles from the second conveying surface upstream and at least one return conveyor having a fourth conveying surface adapted to move articles from the third conveying surface to the first conveying surface. Each of the conveying surfaces may be defined by a plurality of powered rollers. Clusters of articles tend to recirculate around the recirculation bed and the first conveying surface as individual articles of the cluster are pulled away along the first conveying surface. A take-away conveyor at the discharge portion includes a flow controller controlling the flow of articles discharged from the discharge portion.
