[0024] The sheet processing apparatus includes a rotating sheet beating body and a sheet processing device according to the present invention. The sheet processing apparatus is a device for processing sheets. The sheet processing apparatus includes a rotating sheet beating body.

[0025] The paper sheet beating rotor is attached to a shaft member and rotates to beat paper sheets, thereby stacking the paper sheets. Paper sheets are, for example, thin, sheet-like or bill-like objects of a standard size, such as banknotes, securities, gift certificates, and ballot papers. Note that the material of paper sheets is not limited to paper. Paper sheet processing devices include, for example, currency deposit / withdrawal machines, securities processing devices, and ballot processing devices.

[0026] In this embodiment, the paper sheet processing device is a currency depositing and dispensing machine used in banks, stores, etc. The currency depositing and dispensing machine is a device into which banknotes (one example of paper sheets) are inserted, accumulates the inserted banknotes inside, and dispenses the banknotes with their front and backs aligned in response to an operator's operation.

[0027] In the following description, the direction of arrow U shown in Figures 1 and 2 will be referred to as "upward," the direction of arrow D as "downward," the direction of arrow F as "forward," and the direction of arrow B as "rearward" with respect to the sheet beating rotor and the sheet processing device. The direction perpendicular to the paper surface in Figures 1 and 2 will be referred to as the "left-right direction."

[0028] [Paper sheet processing device] As shown in Fig. 1, the sheet processing device 1 has a housing 11 having a substantially rectangular parallelepiped shape, and performs processes such as the input and output of banknotes. The sheet processing device 1 includes an input unit 12, an output unit 13, a plurality of stacking units 14 for stacking sheets, a reject unit 15 for stacking rejected sheets, a transport unit 16 for transporting sheets, and a sheet beating rotor 3. The input unit 12 has an input port 12a through which banknotes are input from outside. The output unit 13 has an output port 13a through which sheets are output to the outside.

[0029] The conveying unit 16 has a plurality of belts and rollers, and a motor for driving these, and conveys paper sheets. The conveying unit 16 is connected to the input unit 12. Paper sheets inserted through the input port 12a are conveyed one by one by the conveying unit 16 at predetermined intervals.

[0030] The transport unit 16 is equipped with a recognition unit 16a that recognizes paper sheets. The conveyed paper sheets are recognized by the recognition unit 16a for their denomination, authenticity, fitness, front and back, etc. The recognized paper sheets are transported to a plurality of stacking units 14 connected to the transport unit 16 or to a rejection unit 15 that accumulates rejected sheets. Rejected sheets include paper sheets in poor condition, such as those that are folded or torn.

[0031] The conveying unit 16 is connected to a plurality of stacking units 14. The paper sheets conveyed by the conveying unit 16 are sorted by type and stacked in the stacking units 14. The plurality of stacking units 14 are connected to the dispensing unit 13 via the conveying unit 16.

[0032] As shown in Fig. 2, the dispensing unit 13 is connected to the transport unit 16. The terminal end 16b of the transport unit 16 is located inside the dispensing unit 13. The dispensing unit 13 faces the outside of the housing 11 and includes a dispensing opening 13a and a holding unit 13b that holds paper sheets in a stacked state. The stacked paper sheets 2 are dispensed from the dispensing opening 13a.

[0033] As shown in FIG. 2, the terminal end 16b of the conveying section 16 in the dispensing section 13 is provided with a shaft member 16c extending in the left-right direction of the housing 11 and a sheet beating rotor 3 attached to the outer periphery of the shaft member 16c and rotating clockwise together with the shaft member 16c. Multiple sheet beating rotors 3 are provided at intervals along the direction of extension of the shaft member 16c. A sheet 2 enters the dispensing section 13 from the terminal end 16b of the conveying section 16 and floats above the dispensing section 13 before being stacked. If a subsequent sheet 2 enters the dispensing section 13 while a sheet 2 is falling into the holding section 13b, the sheets come into contact with each other, resulting in stacking problems. The sheet 2 is beaten by the sheet beating rotor 3, causing it to be stacked in the holding section 13b before the subsequent sheet 2 enters the dispensing section 13.

[0034] [Rotating paper sheet beating device] 3, the paper sheet beating rotor 3 is a member that rotates around the rotation axis X to beat paper sheets, and includes a cylindrical base 31 provided along the outer circumferential surface of the shaft member 16c, and a plurality of contact portions 32 that extend in a direction away from the rotation axis X of the shaft member 16c and can come into contact with paper sheets. The paper sheet beating rotor 3 of this embodiment includes eight contact portions 32. The eight contact portions 32 are arranged at equal intervals around the rotation axis X.

[0035] In this embodiment, the base 31 is made of plastic. However, the material of the base 31 is not limited to this and may be rubber or metal. Eight recesses 33 are arranged at equal intervals on the outer peripheral surface of the base 31. The contact portion 32 is formed by bundling a plurality of hair-like members 32a. The hair-like members 32a are planted in the recesses 33 in a bundled state.

[0036] The hair-like members 32a are made of nylon resin, which is inexpensive and has excellent abrasion resistance.

[0037] The diameter of the recess 33 is 16 mm. The diameter of the hair-like members 32a is 0.15 mm or less and 0.07 mm or more. As the diameter of the hair-like members 32a becomes smaller, it becomes more difficult for the sheets to be knocked down. By placing a bundle of small-diameter hair-like members 32a in the recess 33, it becomes easier to knock down the sheets, and the impact sound of hitting the sheets can be reduced, thereby suppressing noise. Furthermore, since the sheet beating rotor 3 is provided in the outlet 13 facing the outside of the housing 11, the impact sound is likely to leak outside the sheet processing device 1 and become noise. According to this embodiment, noise from the sheet processing device 1 can be suppressed.

[0038] [Quietness and accumulation performance of hair-like material] The "quietness performance" and "stacking performance" of the contact portion 32 formed by bundling the hair-like members 32a were evaluated. The quietness performance was evaluated by measuring the volume of the impact sound of the contact portion 32 striking the paper sheets. The stacking performance was evaluated by changing the spacing between paper sheets 2 (inter-note distance) and checking the inter-note distance at which the contact portion 32 could successfully stack the paper sheets 2. The smaller the inter-note distance, the better the stacking performance.

[0039] Four types of contact portion 32 samples were prepared, each with a constant diameter of recess 33 but different diameters and numbers of hair-like members 32a. These will be referred to as samples A, B, C, and D in order of diameter from largest to smallest.

[0040] The diameter of the hair-like members 32a in each sample was 0.15 mm for Sample A, 0.132 mm for Sample B, 0.1 mm for Sample C, and 0.07 mm for Sample D. The number of hair-like members 32a was set so that they would fit in the recessed portion 33: 123 for Sample A, 162 for Sample B, 282 for Sample C, and 535 for Sample D.

[0041] For comparison purposes, a rubber contact portion (conventional product) was prepared that was the same length as each sample and had the same thickness as the recess 33.

[0042] An experimental device simulating the ejection unit 13 of the paper sheet processing apparatus 1 was prepared, and two samples of the same type were placed on the shaft member 16c with a gap between them in the axial direction.

[0043] The noise reduction performance was evaluated as follows. A 20 mm thick sound-absorbing sponge was placed on a wooden desk, and the experimental device was placed on top of the sound-absorbing sponge. A sound-collecting microphone was installed 1 m horizontally away from the shaft member 16c. The experimental device was operated for 5 seconds, and two sheets of paper were stacked and processed in succession. The volume of the impact sound when the two sheets were stacked and held in a stacked state was measured with the sound-collecting microphone. The measurement was performed five times, and the average value was calculated to obtain the measurement result.

[0044] The measurement results for noise reduction are as follows: The rubber contacts are 62.5 dB. Sample A (0.15 mm diameter) is 60.8 dB; Sample B (0.132 mm diameter) is 57.3 dB; Sample C (0.1 mm diameter) is 58.0 dB. Sample D (diameter 0.07 mm) is 56.4 dB.

[0045] The results of the noise reduction measurements confirmed that the smaller the diameter of the hair-like members 32a, the higher the noise reduction performance. In all of Samples A to D, the impact noise was lower than that of the rubber contact portion. Therefore, from the standpoint of noise reduction, it is considered preferable that the diameter of the hair-like members 32a be 0.15 mm or less. Furthermore, it is considered even more preferable that the diameter of the hair-like members 32a be 0.132 mm or less.

[0046] The smaller the diameter of the hairs 32a in the sample, the larger the number of hairs 32a, but the smaller the volume of the impact sound. Therefore, it is recognized that the diameter of the hairs 32a has a greater effect on the volume of the impact sound than the number of hairs 32a.

[0047] The stacking performance was evaluated as follows: The experimental device was operated, and the inter-note distance was changed to check whether the paper sheets 2 could be stacked normally. Four inter-note distances were used: 25 mm, 20 mm, 15 mm, and 10 mm.

[0048] The distance between the bills that allows for the normal stacking of paper sheet 2 is: The rubber contact areas are 25mm and 20mm. Sample A (0.15 mm diameter) is 25 mm, 20 mm, 15 mm, and 10 mm. Sample B (0.132 mm diameter) is 25 mm, 20 mm, 15 mm, and 10 mm. Sample C (0.1 mm diameter) is 25 mm, 20 mm, and 15 mm. Sample D (diameter 0.07 mm) is 25 mm.

[0049] The evaluation results of stacking performance indicate that the smaller the diameter of the hair-like members 32a, the more likely it is that stacking will not proceed normally when the inter-card distance is small. Therefore, it is believed that the larger the diameter of the hair-like members 32a, the better the stacking performance. It was confirmed that Samples A to C had better stacking performance than the rubber contact parts. Furthermore, while the stacking performance of Sample D was inferior to that of the rubber contact parts, it was confirmed that proper stacking was possible when the inter-card distance was 25 mm. Therefore, from the perspective of stacking performance, it is preferable that the diameter of the hair-like members 32a be 0.07 mm or more. Furthermore, it is even more preferable that the diameter of the hair-like members 32a be 0.1 mm or more.

[0050] [Another embodiment] (1) In the above embodiment, an example has been described in which the paper sheet beating rotor 3 has eight contact portions 32, and the eight contact portions 32 are evenly spaced around the rotation axis X. As shown in FIG. 4, the paper sheet beating rotor 3 may have four contact portions 32, and the four contact portions 32 may be evenly spaced around the rotation axis X. The number of contact portions 32 may be approximately 2 to 16 depending on the installation location, etc.

[0051] [Quietness and accumulation performance of hair-like material] The "silence performance" and "accumulation performance" were evaluated under the same conditions as in the above evaluation for the paper sheet beating rotor 3 having four contact portions 32. In this embodiment, the diameter of the recess 33 is 14 mm.

[0052] The measurement results for noise reduction are as follows: The rubber contacts are 71.0 dB. Sample A (0.15 mm diameter) is 59.3 dB; Sample B (0.132 mm diameter) is 55.7 dB; Sample C (0.1 mm diameter) is 55.6 dB; Sample D (diameter 0.07 mm) is 48.3 dB.

[0053] The results of the noise reduction measurements confirmed that the smaller the diameter of the hair-like members 32a, the higher the noise reduction performance. In all of samples A to D, the impact noise was quieter than with the rubber contact parts. In other words, the results were similar to when the number of contact parts 32 was eight.

[0054] From the above evaluation results, even in the case where the number of contact portions 32 is four, it is recognized that from the viewpoint of noise reduction performance, it is preferable that the diameter of the hair-like members 32a is 0.15 mm or less. It is also recognized that it is more preferable that the diameter of the hair-like members 32a is 0.132 mm or less. From the viewpoint of accumulation performance, it is recognized that, as in the case where the number of contact portions 32 is eight, it is preferable that the diameter of the hair-like members 32a is 0.07 mm or more. It is also recognized that it is more preferable that the diameter of the hair-like members 32a is 0.1 mm or more.

[0055] (2) In the above embodiment, an example has been described in which all of the contact portions 32 of the paper sheet beating rotor 3 are configured with hair-like members 32a. The paper sheet beating rotor 3 may have both the contact portions 32 of the hair-like members 32a and contact portions of other shapes (for example, rubber plate-like contact portions). Furthermore, the contact portions 32 of the hair-like members 32a and contact portions of other shapes may be arranged alternately around the rotation center axis X.

[0056] (3) The contact portions 32 do not have to be arranged evenly as long as they are arranged at intervals in the circumferential direction of the rotation center axis X.

[0057] (4) The paper sheet processing device 1 may include a paper sheet beating rotor 3 having a contact portion 32 of a hair-like member 32a and a paper sheet beating rotor 3 having a contact portion of another form, spaced apart in the extension direction of the shaft member 16c.

[0058] (5) The paper sheet beating rotor 3 is provided in the dispensing unit 13 in the above example. The paper sheet beating rotor 3 may be provided in a plurality of stacking units 14 or rejecting units 15 that are not connected to the outside of the housing 11, as long as the stacking units 14 and rejecting units 15 are locations where paper sheets are stacked.

[0059] (6) In the above embodiment, the bristle members 32a are made of nylon resin. However, as long as the impact noise can be reduced, the bristle members 32a may be artificial bristles made of a resin material such as polyacetal resin, polyester, or polyolefin, or natural bristles such as pig bristles. Furthermore, these may be combined. [Industrial Applicability]

[0060] The present invention can be used in a paper sheet beating rotor and a paper sheet processing device used to transport and stack paper sheets. [Explanation of symbols]
