Abstract

An impeller type banknote separation device includes a conveying impeller configured to separate banknotes, an impeller phase detecting sensor and a banknote conveying mechanism, and further includes at least one U-shaped sensor fixed on the conveying impeller and configured to detect whether a banknote enters the conveying impeller. The U-shaped sensor includes a signal transmitting end and a signal receiving end located at a same side of the conveying impeller, the signal transmitting end and the signal receiving end are spaced from each other with a certain interval and form an open end of the U-shaped sensor. The technical solution of detecting whether the banknote is inserted into the impeller by the U-shaped sensor to control the rotation of the conveying impeller has a higher accuracy compared with the conventional technology.

First claim

The invention claimed is:

1. An impeller type banknote separation device, comprising a conveying impeller configured to separate banknotes, an impeller phase detecting sensor and a banknote conveying mechanism, the conveying impeller having a plurality of blades uniformly distributed in a spiral radial form, wherein the impeller type banknote separation device further comprises at least one U-shaped sensor fixed on the conveying impeller and configured to detect whether a banknote enters the conveying impeller, the U-shaped sensor comprises a signal transmitting end and a signal receiving end located at a same side of the conveying impeller, the signal transmitting end and the signal receiving end are spaced from each other with a certain interval and form an open end of the U-shaped sensor, and the open end of the U-shaped sensor faces to a direction in which the banknote enters the conveying impeller.

2. The impeller type banknote separation device according to claim 1 , wherein two guiding plates are arranged at the open end of the U-shaped sensor, the two guiding plates are spaced from each other with a predetermined distance and are respectively inclined at a predetermined angle to form a groove having a splayed cross-section, the groove having the splayed cross-section comprises a groove opening having a wide opening and a groove bottom having a narrow opening, the groove opening faces to a direction in which the banknote enters the conveying impeller, and the groove bottom faces to the open end of the U-shaped sensor.

3. The impeller type banknote separation device according to claim 1 , wherein the banknote conveying mechanism comprises an O-shaped belt and a belt pulley configured to convey the banknote, and the O-shaped belt and the belt pulley form a banknote conveying passage and are powered by a stepper motor.

4. The impeller type banknote separation device according to claim 3 , wherein a space between extension lines of tangent lines of, the two adjacent blades closest to the banknote conveying passage of the conveying impeller, is an impeller space into which the banknote is insertable, and the impeller space and the banknote conveying passage intersect or overlap with each other to form a closed conveying passage.

5. The impeller type banknote separation device according to claim 4 , wherein the impeller type banknote separation device comprises a pair of conveying impellers coaxially arranged in the banknote conveying passage, and one U-shaped sensor is fixedly mounted on at least one side of each of the pair of conveying impellers.

6. The impeller type banknote separation device according to claim 2 , wherein the banknote conveying mechanism comprises an O-shaped belt and a belt pulley configured to convey the banknote, and the O-shaped belt and the belt pulley form a banknote conveying passage and are powered by a stepper motor.

7. A financial self-service equipment, comprising a banknote-in/out port, a banknote discriminator, a temporary storage area, a deposit box, a circulation banknote box and a banknote conveying passage, wherein at least one of the banknote-in/out port and the temporary storage area is provided with an impeller type banknote separation device comprising a conveying impeller configured to separate banknotes, an impeller phase detecting sensor and a banknote conveying mechanism, the impeller type banknote separation device further comprises at least one U-shaped sensor fixed on the conveying impeller and configured to detect whether a banknote enters the conveying impeller, the U-shaped sensor comprises a signal transmitting end and a signal receiving end located at a same side of the conveying impeller, the signal transmitting end and the signal receiving end are spaced from each other with a certain interval and form an open end of the U-shaped sensor, and the open end of the U-shaped sensor faces to a direction in which the banknote enters the conveying impeller.

8. The financial self-service equipment according to claim 7 , wherein two guiding plates are arranged at the open end of the U-shaped sensor, the two guiding plates are spaced from each other with a predetermined distance and are respectively inclined at a predetermined angle to form a groove having a splayed cross-section, the groove having the splayed cross-section comprises a groove opening having a wide opening and a groove bottom having a narrow opening, the groove opening faces to a direction in which the banknote enters the impeller, and the groove bottom faces to the open end of the U-shaped sensor.

9. The financial self-service equipment according to claim 7 , wherein the banknote conveying mechanism comprises an O-shaped belt and a belt pulley configured to convey the banknote, and the O-shaped belt and the belt pulley form a banknote conveying passage and are powered by a stepper motor.

10. The financial self-service equipment according to claim 9 , wherein a space between extension lines of tangent lines of the two adjacent blades closest to the banknote conveying passage of the conveying impeller, is an impeller space into which the banknote is insertable, and the impeller space and the banknote conveying passage intersect or overlap with each other to form a closed conveying passage.

11. The financial self-service equipment according to claim 10 , wherein the impeller type banknote separation device comprises a pair of conveying impellers coaxially arranged in the banknote conveying passage, and one U-shaped sensor is fixedly mounted on at least one side of each of the pair of conveying impellers.
