Appl. No.:

16/573887

International Classification:

B65H 3/12
B65H 1/02
B65H 9/16
B65H 3/66
B65H 7/16

Abstract:

A device for reducing rotation of an article during singulation of a stack of articles is disclosed. The device may include a torsion element, a rotatable member configured to rotate about an elongated axis of the torsion element between a first position and a second position, and a revolving member coupled to the rotatable member. An outer surface of the revolving member contacts a drive belt in the first position and an article in the second position. The torsion element exerts torque on the rotatable member when it moves from the first position towards the second position. The torque causes the outer surface of the revolving member to apply a frictional force to the article, thereby minimizing rotation of the article. Systems and methods of singulating articles are also disclosed.
