While ensuring the flattening effect, we need to consider reducing the scraping wear of the bent portion on the surface of the sheet. In the embodiment of the invention, the edge is provided with a chamfer having a radius of 0 to 2 mm.

In this embodiment, it is preferable that the radius R of the edge is 0.2 mm.

Referring to FIG. 1 and FIG. 2, in the embodiment of the present invention, the outer channel transmission unit and the inner channel transmission unit are respectively fixed on the side plate 41 and the side plate 42.

Please refer to FIG. 8. FIG. 8 is a schematic diagram showing the internal structure of a financial self-service device according to the present invention. Figure.

An embodiment of a financial self-service device provided by the present invention includes:

The banknote module 101, the upper upper channel module 102, the upper lower channel module 103, the banknote identification module 104, the lower channel module 105, the lower conveying channel, the upper drum type cash box 106, the lower drum type cash box 107, the rear collection box 108 , the front recovery bin 109 and the first embodiment shown in FIGS. 3 to 7 or the second embodiment of FIG. 9 or the third embodiment of FIG. 10 or the fourth embodiment of FIG. Flattening device 110.

Wherein, the sheet flattening device 110 may be connected in parallel with the banknote module dispensing path 101a and/or the sheet flattening device 110 in parallel with the banknote path 105a of the lower conveying path.

The sheet flattening apparatus 110 mentioned in the following with reference to the first embodiment shown in FIGS. 3 to 7 or the second embodiment of FIG. 9 or the third embodiment of FIG. 10 or the fourth embodiment of FIG. 11 Description of the financial self-service device application scenario:

In the first case, when the sheet flattening device 110 is connected in parallel with the banknote module dispensing path 101a, when the banknote passes from the upper drum type box 106 or the lower drum type box 107 through the intermediate straight passage to the lower conveying passage to the upper portion The area is discriminated and counted by the banknote recognition module 104 through the reversing mechanism and judges whether the banknote has a curl condition. If it is a curled banknote, it passes through the upper channel 102, and then passes through the reversing mechanism to the sheet flattening device 110, and finally curls. After the banknote is flattened, the banknotes in the banknote module 101 can be smoothly folded, and the banknotes are not folded due to the curled banknotes. If the identification module 104 determines that no banknotes have passed, the reversing mechanism passes the normal dispensing path 101a to the banknote stacking. The advantage of placing the banknote path at the banknote module 101 is that it does not have any effect on the banknotes during the banknote process.

In the second case, the sheet flattening device 110 can also be connected in parallel to the banknote path 105a of the lower conveying path, when the banknote passes from the upper drum type box 106 or the lower drum type box 107 to the lower conveying passage through the intermediate straight passage. The paper is judged by reading the storage information of the banknote in the cash box, and if it is judged to be a curled banknote, passes through the sheet flattening device 110 through the reversing mechanism, and is flattened to reach the upper region, and the reversing mechanism is passed. The banknote identification module 104 performs screening and counting, and the

upper channel

102b, 102a passes through the reversing mechanism to the banknote opening of the banknote module 101. If it is judged that the banknote that is not curled passes, the reversing mechanism reaches the upper region through the normal banknote path 105a, and is discriminated and counted by the banknote recognition module 104 through the reversing mechanism, and passes through the upper portion. The channel 102 is then fed to the banknote opening of the banknote module 101 via the reversing mechanism. The advantage of placing the banknote at the lower conveying path is that the curled banknote is flattened and then enters the upper zone passage to reduce the banknote rate of the banknote in the upper zone. In addition, during the process of adding money, the banknote passes through the normal banknote path 105a.

It can be concluded from the above technical solution that the present invention provides a sheet flattening device and a financial self-service device, which have the following advantages:

(1), the effect of achieving flattening is good, and the effect of flattening the curling medium is also very good;

(2) The structure is simple and reliable, and the failure rate and card rate are low;

(3) The structure is practical and the manufacturing cost is low.

The above description is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can also make several improvements and retouchings without departing from the principles of the present invention. It should be considered as the scope of protection of the present invention.
