Title:
STACKER WHEEL CONTROL APPARATUS AND METHOD UTILIZING START-STOP SYNCHRONIZATION
Document Type and Number:
WIPO Patent Application WO2001096220
Kind Code:
A3
Abstract:
An inspection and/or processing apparatus for sheets such as banknotes includes a stacker wheel arrangement in which, rather than continuously rotating the stacker wheel (20) and decelerating or accelerating the wheel to adjust the wheel speed in order to cause the grooves (22) to align with the entrance chute at the same time that sheets arrive at the wheel, the stacker wheel is rotated only between sheet arrivals, and only for the purpose of indexing the stacker wheel to a new position at which a sheet can enter the stacker wheel without jamming. Indexing of the stacker wheel follows a predetermined profile, and the stacker wheel held stationary at each predetermined aligned position until a respective individual sheet has entered the stacker wheel.
