Device for transporting banknotes in a cash dispenser
View Patent ↗In the case of an apparatus for transporting banknotes, within an automated teller machine, between at least one banknote cassette, for storing banknotes which are to be dispensed, and a dispensing location or between the latter and a receiving container for banknotes which have been drawn back, comprising a bundle-transporting section which is located between the dispensing location and a collecting location, at which banknotes which have been removed individually from the banknote cassette are collected into a bundle, and has two belt drives, a bundle of banknotes being gripped, and transported, between the mutually parallel endless belts of the belt drives, said endless belts circulating in the same direction in each case over a drive roller, and also has a drive arrangement for driving the belt drives, characterized in that the belt drives can be driven at different speeds at least in the direction from the dispensing location to the receiving container.
1. An apparatus for transporting banknotes, within an automated teller machine, between at least one banknote cassette, for storing banknotes which are to be dispensed, and a dispensing location or between the latter and a receiving container for banknotes which have been drawn back, comprising a bundle-transporting section which is located between the dispensing location and a collecting location, at which banknotes which have been removed individually from the banknote cassette are collected into a bundle, and has first and second belt drives, a bundle of banknotes being gripped, and transported, between mutually parallel endless belts of the first and second belt drives, said endless belts circulating in the same direction in each case over a drive roller, and also has a drive arrangement for driving the first and second belt drives, wherein the first and second belt drives can be driven at different speeds at least in the direction from the dispensing location to the receiving container and wherein, the drive roller of a first belt drive and a parallel intermediate shaft of a third belt drive are coupled in a rotationally fixed manner to a motor.
2. The apparatus as claimed in claim 1 , wherein the drive arrangement, for each belt drive, has a dedicated motor, of which at least one can be controlled in terms of speed.
3. The apparatus as claimed in claim 1 , wherein the first and second belt drives can be driven by a common motor, and in that one of the first and second belt drives can be coupled to the motor in one transporting direction via a first gear train and in the other transporting direction via a second gear train with a different transmission from the first gear train.
4. The apparatus as claimed in claim 3 , wherein the drive roller of the second belt drive is in torque-transmitting connection with the drive roller of the first belt drive via a first one-way clutch and with the intermediate shaft via a second one-way clutch, of which the direction of action is oriented counter to that of the first one-way clutch.
5. The apparatus as claimed in claim 4 , wherein one of the one-way clutches is a latching freewheel.
6. The apparatus as claimed in claim 4 , wherein one of the one-way clutches is a clamping-body freewheel.
7. The apparatus as claimed in claim 5 , wherein the other one-way clutch is a slip clutch.
8. The apparatus as claimed in claim 4 , wherein the two one-way clutches are vibratory-spring clutches which are controlled by friction clutches with a low torque.
9. The apparatus as claimed in claim 1 , wherein the bundle-transporting section is coupled to a second transporting section comprising two belt drives, an endless belt of one belt drive being guided over the first drive roller and the endless belt of the second belt drive being guided over a drive roller which is seated on the intermediate shaft.
10. The apparatus as claimed in claim 9 , wherein the second transporting section connects the bundle-transporting section to the collecting location and, via a diverter, to the receiving container.
