Abstract
The device has a feed roller with a high friction rubber segment which picks notes one at a time for each roller revolution or cycle. A counter-rotating separator roller normally prevents picking doubles. A cooperative doubles detector detects doubles when picked and returns the doubles to the note supply stack. The picker mechanism has a biasing lever which holds the note stack out of contact with the feed roller against stack pressure until the friction segment is in note separating and picking position.
Claims21
Friction picker mechanism for an ATM paper note dispenser of a type in which notes at the end of a note supply stack normally pressed toward said mechanism are separated and picked one at a time from said stack by associated friction areas of a rotatable feed roller and friction separator means when said roller is driven in note feeding direction by drive means;
- wherein the improvement comprises:
- (a) a rotatable feed roller having a smooth cylindrical surface provided with arcuate rubber friction segment means interrupting said smooth surface;
- (b) rubber friction separator means directed toward and free of contact with said feed roller;
- (c) doubles detector means including note thickness gauging devices located adjacent said separator means and engaged with and actuated by notes as said notes are fed by said feed roller;
- (d) reversible drive means operatively connected with said feed roller which drive means when energized normally drives said feed roller in note feeding direction with said friction segment means engaging and picking stack end notes and driving said notes one at a time successively between said feed roller and said separator means, and then past said thickness gauging devices;
- (e) said friction separator means engaging the inner surfaces of and resisting movement of said notes being fed as said notes are driven between said feed roller and separator means, normally to separate doubles from the end notes being fed;
- (f) said doubles detector means also including sensor means adapted to sense the detection of unseparated doubles by said note thickness gauging devices when doubles are driven past said note thickness gauging devices;
- and
- (g) said sensor means when sensing the detection of doubles reversing said drive means to return said detected doubles back to said stack by reverse feed roller movement, whereupon normal drive means movement of the feed roller in forward note feeding direction is restored and said drive means again is reversed repeatedly until the doubles are separated from the end note being fed, by said back and forward note scrubbing of the doubles between said friction segment means and said friction separator means.
