Sensor device in a bank note processing machine
View Patent ↗A sensor device in a banknote processing machine comprising a transport device by means of which banknotes to be processed are transported past the sensor device, a cleaning device that cleans the sensor device or a transparent region of the sensor device, and a control device that controls the components of the banknote processing machine. The sensor device includes means for enlarging the spacing between the transport device and the sensor device. The control device controls the means and the cleaning device in such a way that the spacing between the transport device and the sensor device is enlarged by the means while the cleaning device cleans the sensor device.
1. A sensor device in a bank note processing machine, comprising:
a transport device arranged to transport bank notes to be processed past a sensor device;
a cleaning device arranged to clean the sensor device or a transparent region of the sensor device;
a control device controlling the constituents of the bank note processing machine;
means for enlarging a distance between the transport device and the sensor device,
wherein the control device drives the means and the cleaning device in such a way that the distance between the transport device and the sensor device is enlarged by the means during the cleaning of the sensor device by the cleaning device.
2. The sensor device according to claim 1 , wherein the means move the transport device or belts of the transport device away from the sensor device.
3. The sensor device according to claim 2 , wherein the means are formed by a lifting magnet and a guiding device acting on the belts.
4. The sensor device according to claim 3 , wherein the guiding device is formed by a skid-shaped sheet-metal part.
5. The sensor device according to claim 3 , wherein the guiding device is formed by rolls or rollers.
6. The sensor device according to claim 1 , wherein the means for enlarging the distance between the transport device and the sensor device are arranged on one side of the sensor device, regarded in the transport direction of the transport device.
7. The sensor device according to claim 1 , wherein the means for enlarging the distance between the transport device and the sensor device includes a first actuator arranged on a first side of the sensor device in the transport direction of the transport device and a second actuator arranged on a second side of the sensor device in the transport direction of the transport device.
8. A sensor device in a bank note processing machine, comprising:
a transport device arranged to transport bank notes to be processed past a sensor device;

a control device controlling the constituents of the bank note processing machine;
an enlarging device arranged for enlarging a distance between the transport device and the sensor device, wherein the control device drives the enlarging device and the cleaning device in such a way that the distance between the transport device and the sensor device is enlarged by the enlarging device during the cleaning of the sensor device by the cleaning device.
9. The sensor device according to claim 8 , wherein the enlarging device includes a lifting magnet and a guiding device acting on the belts.
10. A sensor device in a bank note processing machine, comprising:
a transport device arranged to transport bank notes to be processed past a sensor device;
a cleaning device arranged to clean the sensor device or a transparent region of the sensor device;
a control device controlling the constituents of the bank note processing machine;
an actuator configured to enlarge a distance between the transport device and the sensor device,
wherein the control device drives the means and the cleaning device in such a way that the distance between the transport device and the sensor device is enlarged by the means during the cleaning of the sensor device by the cleaning device.
11. The sensor apparatus according to claim 10 , wherein the actuator moves the transport device or belts of the transport device away from the sensor device.
12. The sensor apparatus according to claim 11 , wherein the actuator includes a lifting magnet and a guiding device acting on the belts.
13. The sensor apparatus according to claim 12 , wherein the guiding device is formed by a skid-shaped sheet-metal part.
14. The sensor apparatus according to claim 12 , wherein the guiding device is formed by rolls or rollers.
15. The sensor apparatus according to claim 10 , wherein the actuator is arranged on one side of the sensor device, regarded in the transport direction of the transport device.
16. The sensor apparatus according to claim 10 , wherein the actuator includes a first actuator device arranged on a first side of the sensor device in the transport direction of the transport device and a second actuator device arranged on a second side of the sensor device in the transport direction of the transport device.
