Abstract

(57) [Summary] [Purpose] To prevent dust such as paper dust from adhering to the surface of the roller that constitutes the double feed detection mechanism of a paper sheet counter. [Structure] In the double feed detection mechanism of a paper sheet counting machine, rollers 11 and 12, between which paper sheets 21 pass, are mounted on the surfaces of rollers 11 and 12, which are held by mounting brackets 15 and 16 fixed to the frame of the counting machine. The brushes 22A, 22B come into contact with each other, and dust such as paper powder is prevented from adhering to the surfaces of the rollers 11, 12. One mounting bracket 15A is attached to a lever that rotates to follow the thickness of the paper sheet, and the cleaning means 22A always maintains a constant angle with respect to the roller 11.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is a paper sheet counting machine, especially a double feed (two-sheet feeding) paper sheet counting machine. ) Regarding the detection mechanism.

0002

[Conventional technology]

The double feed detection mechanism of a conventional sheet counting machine is shown in the side view of Figure 3. When paper sheet 21 passes between rollers 11 and 12, roller 11 rises due to its thickness. The detection shaft 14 rotates through the lever 13. The rotation of this detection shaft 14 causes the paper sheet to be detected. Measure the thickness of class 21. In Figure 3, 17 and 18 are belts, and paper sheets 21 are attached to these belts. It is fed out between routes 17 and 18 in the direction of the arrow 1, and in some cases it advances in the direction of the arrow 2. It will be done.

0003 The mechanism for detecting the thickness of paper sheets described above will be explained with reference to the schematic side view of Fig. 4. Then, the shaft of roller 12 is fixed to the frame of the counter, so it is always constant. The shaft of roller 11 is a lever that is used to measure the thickness. 13, the lever 13 is fixed to a rotatable detection shaft, and the position of the roller 11 is varies depending on the thickness of the paper sheet. Paper sheet 21 is passed between rollers 11 and 12 in the direction of arrow 1. When it passes, the detection shaft 14 rotates in the direction of arrow 3 via the lever 13 due to its thickness.

0004 Referring to Figure 5, the angle sensor 19 and amplifier board are directly connected to the detection axis 14. 20 converts the rotation angle of the sensing shaft 14 into a voltage output. For voltage output, paper sheets are banknotes. In this case, each banknote decreases by 0.89V, so one banknote reduces the voltage by 3.0V compared to the reference voltage of 4V. 11V, 2.22V for 2 bills, 1.33V for 3 bills, and can detect up to 3 bills.

[Problem that the idea aims to solve]

If the paper sheet counter shown in Figure 3 is used for a long time, ink on the paper sheets may cause the problem. This may cause paper dust etc. to adhere to the roller, making it impossible to accurately measure the thickness. Ru. Errors in measurement should not be allowed, so check the machine regularly. It is important that no errors occur until inspection, and to do so, There is a need for a means to reliably remove paper dust etc. adhering to the paper. Therefore, this invention can be used to measure the thickness of paper sheets in the paper sheet thickness detection mechanism of a paper sheet counter. To provide a means for preventing dust such as paper powder from adhering to a rotary roller. With the goal.

[0006]

[Means to solve the problem]

The paper sheet counter of the present invention has a double feed detection mechanism of the paper sheet counter. The cleaning means that comes into contact with the surface of the roller through which the paper sheets pass is the frame of the counting machine. It is characterized by being held by a mounting bracket fixed to the The means is attached to a mounting bracket fixed to the lever of the double feed detection mechanism and The cleaning means is characterized in that it rotates together with a lever that rotates according to the thickness of the paper sheet. do.

[0007]

[Effect]

In other words, the present invention maintains constant contact with a pair of rollers used to measure the thickness of paper sheets. A cleaning means is provided to prevent dust such as paper powder from adhering to the roller. of this invention In one embodiment, both cleaning means are fixed to the frame of the counter; in another embodiment, one of the cleaning means is fixed to the frame of the counter; The cleaning means of the roller is fixed to the lever provided for thickness measurement, and the roller is fixed to the lever provided for thickness measurement. When the roller moves, the cleaning means adapts to this movement and is always in contact with the roller. .

[0008]

【Example】

Hereinafter, one embodiment of the present invention will be specifically described with reference to the side view of FIG. In Figure 1 , parts that are the same as those shown in Figure 3 are indicated with the same symbols, and 22A and 22B are clean hands. The brushes are in stages, and 15 and 16 are mounting brackets that hold and fix brushes 22A and 22B respectively. It is.

[0009] In the embodiment shown in Figure 1, both mounting brackets 15 and 16 are both fixed to the frame of the counter. It is worn. Then, the brush 22A fixed to the brush mounting bracket 15 is attached to the roller 11. The brush 22B fixed to the brush mounting bracket 16 is always in contact with the roller 12. When rollers 11 and 12 rotate in this state, brushes 22A and 22B prevent paper dust from adhering to them. , remove any attached paper dust.

0010 In another embodiment of the invention, the mounting bracket 15 of the brush 22A that contacts the roller 11 is A is attached to lever 13, which is a part for measuring thickness. Therefore, brush 22A rotates following the lever 13 and always contacts the roller 11 at a constant angle. Shown in Figure 1 In the embodiment, when the thickness of the paper sheet 21 is large and the rotation of the lever 13 is large, the brush 22A is in a fixed position, so when the lever 13 returns to its original position, the direction of the brush 22A However, the In the second embodiment, the mounting bracket 15A of the brush 22A is fixed to the lever 13, so the brush 22A is fixed to the lever 13. The brush 22A always maintains a constant angle with respect to the roller 11, so the above-mentioned problems do not occur. do not have.

[0011]

[Effect of the idea]

As explained above, according to the present invention, the double feed detection mechanism of the paper sheet counter In this case, the surface of the roller that comes into contact with paper sheets is in constant contact with the cleaning means. This prevents dust such as paper dust from adhering, and even if dust does adhere, it is immediately removed. Since it is removed, it has the effect of preventing errors in measuring the thickness of paper sheets.
