First Claim
1. A package singulation conveyor, comprising:
- a conveying surface traveling in a particular direction; and
a diverting surface having at least a portion extending above said conveying surface and traveling upwardly and away from said conveying surface in a direction generally normal to said particular direction;
wherein packages traveling along said conveying surface having a portion extending to said diverting surface will be diverted from said conveying surface by said diverting surface, and wherein said diverting surface is defined by a rotating cylinder, wherein said rotating cylinder is inclined with an end upstream with respect to said particular direction being lower than an opposite end thereof.

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. Each of the conveying surfaces may be defined by the upper surfaces of a plurality of powered rollers or traveling belts. Clusters of articles tend to recirculate around the recirculation bed and the first conveying surface and provide contact accumulation thereon as individual articles of the cluster are pulled away along the first conveying surface. An output section diverts packages having a width transverse the direction of conveyor travel which is greater than a particular dimension, rotates diverted packages, and returns the rotated packages to the conveyor.

5. A method of removing from a conveying surface side-by-side packages and any package having a lateral dimension with respect to the direction of travel of said conveying surface which exceeds a particular dimension, comprising:
-
providing a vertical guide surface adjacent one side of the conveying surface and a diverting device laterally spaced from said guide surface a distance substantially equal to the greatest lateral package dimension transverse the direction of travel of the conveying surface that is to travel downstream of the conveying surface, said diverting surface including at least a portion extending above said conveying surface;
conveying packages along the conveying surface;
diverting off the conveying surface any packages having any portion contacting said diverting device; and
rotating packages diverted from the conveying surface and returning the rotated packages to the conveying surface. - View Dependent Claims (6, 7, 14)

8. A method of conveying packages along a conveying surface, comprising:
-
providing a conveying surface and a diverting device;
conveying packages along the conveying surface and diverting from said conveying surface with said diverting device each package having a lateral dimension transverse the direction of travel of said conveying surface which is greater than or equal to a particular dimension, said diverting surface including a driven surface having at least a portion extending above said conveying surface; and
rotating packages removed from the conveying surface and returning the rotated packages to the conveying surface downstream of said diverting device.

16. A package singulation conveyor comprising:
-
a conveying surface traveling in a particular direction;
a diverting surface having at least a portion extending above said conveying surface and traveling upwardly and away from said conveying surface in a direction generally normal to said particular direction;
wherein packages traveling along said conveying surface having a portion extending to said diverting surface will be diverted from said conveying surface by said diverting surface, and wherein said diverting surface is defined by a rotating cylinder; and
a rotating device rotating the diverted packages and returning the rotated packages to the conveying surface, wherein said rotating device comprises a radial belt turn conveyor. - View Dependent Claims (19, 20, 21)
