ANTI-ROTATION DEVICE AND METHOD OF USE

摘要

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.

1. A device for reducing rotation of an article comprising:
a base; a drive belt connected to the base a torsion element connected to the base, the torsion element disposed in proximity to the drive belt; a rotatable member coupled to the torsion element, the rotatable member rotatable between at least a first position and a second position about an axis which extends through the center of the torsion element; and a revolving member coupled to the rotatable member and configured to revolve about an axis perpendicular to the base; wherein:
when the rotatable member is in the first position, an outer surface of the revolving member is in contact with the drive belt, andwhen the rotatable member is in the second position, the torsion element applies a torque to the revolving member via the rotatable member, and the outer surface of the revolving member is in contact with, and applies a force to, an article which is also in contact with the drive belt.
