Abstract

PURPOSE:To efficiently smooth creases by detecting the number of creases and the size on a paper money by an angle sensor and changing the amount of moisture to be applied to the paper money and the pressure of a creases smoothing roller corresponding to the state. CONSTITUTION:For the paper money conveyed by a conveying roller 1, the state of creases is detected by an angle sensor 2 provided in the middle of a conveying path 6. Namely, a contactor 11 of the angle sensor is raised only for a moving amount C according to creases 10a of a paper money 10 and a rotary shaft 12 is turned only at an angle theta so as to detect the size of the creases 10a on the paper money 10. Corresponding to the state of creases detected by the angle sensor, the suitable amount of moisture is applied from a steam generation part 3 to the paper money and upper and lower creases smoothing rollers 4a and 4b press the paper money vertically so as to smooth the creases. Thus, the creases of the paper money can be efficiently smoothed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a banknote wrinkle removal device used in an automated device handling banknotes, such as a cash transaction machine.

[Conventional technology]

Conventional automated devices that handle banknotes, such as cash transaction machines, are not equipped with special equipment for smoothing out wrinkles from the banknotes they handle, and old, wrinkled banknotes are manually smoothed out.

[Problem to be solved by the invention]

As mentioned above, conventional automated equipment for handling banknotes requires manual work to remove wrinkles from the banknotes, which is equipped with a special device for removing wrinkles from the banknotes.
Depending on the number and size of wrinkles, that is, the condition of the wrinkles, the banknotes may stop during the conveyance path, resulting in the banknotes being torn, causing errors in counting the number of banknotes, and making it difficult to recognize the banknotes. It has the disadvantage of being

[Means to solve the problem]

The banknote wrinkle removal device of the present invention is installed at the entrance of an automated device, detects wrinkles in banknotes, and smoothes out the wrinkles using steam and rollers, thereby achieving processing capabilities such as banknote conveyance, banknote counting, and banknote recognition. This makes it possible to improve both reliability and reliability.

That is, the bill wrinkle removal device of the present invention includes an angle sensor provided in the middle of a bill conveyance path, and a state in which the number and size of wrinkles on a bill conveyed on the bill conveyance path detected by the angle sensor is memorized. a detection unit, a control unit that controls operations of the steam generation unit and the roller elevation control unit based on information from the state detection unit, and the steam generation that is controlled by the control unit and applies an appropriate amount of moisture to the banknote. at least one pair of wrinkle smoothing rollers that rotate while pressing the bill from above and below, which has been given an appropriate amount of moisture by the steam generating section; and an elevating mechanism for raising and lowering one of the at least one pair of wrinkle smoothing rollers. and the roller elevation control section that is controlled by the control section to control the operation of the elevation section.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention.

In FIG. 1, banknotes are conveyed from a banknote entrance direction (arrow A) to a banknote exit direction (arrow B) by rotation of a banknote transport roller (conveyance roller) 1. The route is a banknote conveyance path (conveyance path) 6 indicated by a broken line. The state of wrinkles in the banknotes conveyed by the conveyance roller 1 is detected by an angle sensor 2 provided in the middle of the conveyance path 6. A method for detecting the state of wrinkles using the angle sensor 2 will be described later.

An appropriate amount of moisture is applied to the banknote from the steam generator 3 according to the state of wrinkles detected by the angle sensor 2. The reason why moisture is applied to the banknote is to loosen the paper fibers of the banknote and improve the effect of removing wrinkles when the wrinkles are removed by the wrinkle removing rollers 4a and 4b.

Next, the banknote is pressed from above and below by upper and lower wrinkle removing rollers 4a and 4b to remove wrinkles. Here, in order to efficiently smooth out the wrinkles, the lower roller 4b is raised by the lifting section 5 in accordance with the state of the wrinkles. As a result, the pressing forces of the upper wrinkle smoothing roller 4a and the lower wrinkle smoothing roller 4b are both increased, thereby increasing the wrinkle smoothing effect.

FIG. 2 is a functional block diagram of the embodiment of FIG. 12.

In FIG. 2, the angle sensor 2 detects the state of wrinkles on the banknote and stores the number and size of the wrinkles in a built-in state storage section 7. The control section 8 controls the operations of the steam generation section 3 and the roller elevation control section 9 based on information from the state storage section 7 . The steam generating section 3 adds moisture to the bill, and the roller elevation control section 9 raises the elevating section 5 that raises and lowers the wrinkle removing roller 4b, and the wrinkle removing rollers 4a and 4b are raised.
Increase the pressing force.

FIG. 3 is a front view showing the operation of detecting the wrinkled state of a banknote by the angle sensor of the embodiment shown in FIG. 1, in which (a) shows a case where the banknote has no wrinkles, and (b) shows a case where the banknote has wrinkles.

In FIG. 3, the contact 1 of the angle sensor is the rotating shaft 12.
and are connected by an arm 13. The contact 11 is a banknote 1
It increases by the amount of movement C due to the wrinkle 10a of 0. As a result, the rotating shaft 12 rotates by an angle θ. The size of the wrinkle 10a on the banknote 10 is detected based on this rotation angle.

〔Effect of the invention〕

As explained above, the bill wrinkle removal device of the present invention detects the number and size of wrinkles on a bill using an angle sensor, and in other words, the condition of the wrinkles on the bill, and applies moisture to the bill in accordance with the condition. By changing the amount of wrinkles and the pressing force of the wrinkle smoothing roller, wrinkles can be effectively smoothed out.
