  • Compact article unscrambler
    Patent number: 6622847
    Abstract: A compact article singulation and accumulation 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 is 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.
