Abstract
An arrangement for feeding documents piecemeal from a document bundle (9) comprises a banknote separator (200) which includes two mutually biased rollers (4,6) that are driven by a drive motor (1) that also drives a dispensing roller (3) which functions to dispense documents from the bundle. The rollers (4,6) of the roll pair are rotationally coupled together via a freewheeling hub. The second roller (6) does not rotate during dispensing of a document. Upon completion of a dispensing operation, the drive direction of the motor (1) is reversed, so as to bring the second roller (6) to a new angular position.
Claims14
A document dispensing apparatus, comprising:
- a document store having a document exit;
- a feed roller for feeding documents out of the document store through the document exit;
- a separation system including a pair of juxtaposed rollers defining a nip to which documents are fed from the document exit;
- a drive motor coupled to one of the rollers to cause one roller to rotate in a document feed direction, the one roller being drivingly coupled to an other roller of the pair via a one-way transmission such that a drive is communicated to the other roller only when the one roller is driven in a direction opposite to the feed direction;
- and
- a shaft secured to the other roller, the shaft being secured to a housing via a first one-way clutch which prevents rotation of the shaft in the feed direction and a pulley connected to the shaft by a second one-way clutch so that drive an be communicated to the other roller.
A document dispensing apparatus, comprising:
- a document store having a document exit;
- a feed roller for feeding documents out of the document store through the document exit;
- a separation system including a pair of juxtaposed rollers defining a nip to which documents are fed from the document exit;
- a drive motor coupled to one of the rollers to cause one roller to rotate in a document feed direction, the one roller being drivingly coupled to an other roller of the pair via a one-way transmission such that a drive is communicated to the other roller only when the one roller is driven in a direction opposite to the feed direction;
- a conveyor which receives the document passing between the pair of rollers, and which conveys the document at an elevated speed;
- a sensor for detecting the presence of the document at an inlet to the conveyor;
- and
- a control unit, the sensor being adapted to cause the control unit to influence a current supply to the drive motor when detecting a leading edge of said document, so as to reduce braking of the document passing through the roller pair and having entered the conveyor, to a selected level.

- a document store having a document exit;
- a feed roller for feeding documents out of the document store through the document exit;
- a separation system including a pair of juxtaposed rollers defining a nip to which documents are fed from the document exit;
- and
- a drive motor coupled to one of the rollers to cause one roller to rotate in a document feed direction, the one roller being drivingly coupled to an other roller of the pair via a one-way transmission such that a drive is communicated to the other roller only when the one roller is driven in a direction opposite to the feed direction, wherein the one-way transmission includes a pair of mutually engaging gearwheels which are carried coaxially by the respective rollers in the roller pair, and the other roller of said roller pair carries its gearwheel via a freewheeling hub.
