A shaft 14 is inserted in the central portion. In FIG. 1, the shaft 14 includes one paper sheet separating / conveying roll 10, but the number of paper sheet separating / conveying rolls 10 provided on the shaft 14 is not particularly limited, and two or more. It may be.

It is sectional drawing. FIG. 3 is a cross-sectional view of the paper sheet separating and conveying roll according to the first embodiment.

  As shown in FIG. 2, the transport member 11 </ b> A and the transport member 11 </ b> B are made of a ring-shaped rubber elastic body having a through hole at the center. The transport member 11A and the transport member 11B have the same shape (hereinafter referred to as the transport member 11). The conveying member 11 of this embodiment corresponds to a “rubber member”.

  The conveying member 11 has a diameter larger than the diameters of the fixing member 12 and the sandwiching member 13 and protrudes in the radial direction so that paper sheets can be separated and conveyed.

  The fixing member 12 has a disk-shaped main body portion 12a having a smaller diameter than the conveying member 11, and convex portions 12b and convex portions 12c that are provided on both side surfaces of the fixing member 12 and fit into the through holes of the conveying members 11. . Here, the convex portions 12b and 12c correspond to “core portions”, and the main body portion 12a serves as one of the support portions.

  Here, the convex part of the fixing member 12 has a circular shape whose end surface is substantially the same as the through hole of the conveying member 11, preferably a slightly larger diameter than the through hole of the conveying member 11 before fitting.

  And the through-hole is provided in the center of the fixing member 12, and the shaft 14 can be inserted here.

  The sandwiching member 13 </ b> A and the sandwiching member 13 </ b> B are disc-shaped members having the same diameter as the main body portion 12 a of the fixing member 12. The sandwiching member 13A and the sandwiching member 13B have the same shape. (Hereafter, it is set as the clamping member 13). The clamping member 13 of the present embodiment corresponds to the other support portion.

  That is, the fixing member 12 of the present embodiment corresponds to “a member having a support portion that is in close contact with one side surface of the rubber member”, and the clamping member 13 has “a support portion that is in close contact with the other side surface of the rubber member”. They correspond to “members”, and both are positioned by contact between the end surfaces of the convex portions 12 b and 12 c and the side surfaces of the holding member 13, and are fastened and fixed by bolts (not shown).

  Note that the sandwiching member 13A and the sandwiching member 13B sandwich the transport member 11A and the transport member 11B via the fixed member 12. A through hole is provided in the center of the clamping member 13 so that the shaft 14 can be inserted.

  As shown in FIG. 3, the paper sheet separating and conveying roll 10 according to the first embodiment inserts the convex portions 12b and 12c of the fixing member 12 into the through holes of the conveying member 11A and the conveying member 11B described above, and conveys them. The clamping member 13A is fixed to the end surface of the member 11A, and the clamping member 13B is fixed to the end surface of the conveying member 11B.

  As shown in FIG. 3, in the paper sheet separating and conveying roll 10 according to the first embodiment, the one side surface of the conveying member 11A and the fixing member 12 are in close contact with each other, and the other side surface of the conveying member 11A is sandwiched. The member 13A is in close contact. Similarly, the side surface on one side of the transport member 11B and the fixing member 12 are in close contact, and the side surface on the other side of the transport member 11B and the sandwiching member 13B are in close contact. In the paper sheet separating and conveying roll 10, the end surfaces of the convex portions 12b and 12c of the fixing member 12 are in close contact with the end surfaces of the holding member 13A and the holding member 13B, respectively, and the fixing member 12 and the holding member 13A. The clamping member 13B is positioned and fixed with respect to the axial direction. The fixing member 12 and the clamping member 13 are positioned and fixed with respect to the axial direction via the conveying member 11, whereby the axial width of the core portion (the convex portions 12 b and 12 c in the present embodiment) is reduced. And the gap between the opposing end surfaces of the clamping member 13A and the fixing member 12 and the clamping member 13B. Here, the distance between the opposing end surfaces of the fixing member 12 and the sandwiching member 13A and the fixing member 12 and the sandwiching member 13B is equal to or slightly smaller than the width in the axial direction of the transport members 11A and 11B. The transport member 11A and the transport member 11B are clamped and fixed in the axial direction with a predetermined pressure. Thereby, the surface deflection of the conveying member 11 can be suppressed, and the surface deflection of the conveying member having a relatively small axial width but a large radial thickness can also be suitably suppressed. The surface deflection referred to here refers to horizontal deflection of the conveying member, that is, lateral deflection of the separation conveying surface of the conveying member.

In the paper sheet separating and conveying roll 10, the crushing rate of the rubber member (conveying member 11) is preferably 0 to 13%, particularly preferably 2 to 13%. When the crushing rate is within this range, surface fluff can be reduced. The crushing rate here is obtained from the following equation.
[Formula 1]

Moreover, it is preferable that 27% or more of each side surface of the conveying member 11A is covered with the fixing member 12 or the sandwiching member 13A, and the ratio (T ₁ / T) between the radial thickness T ₁ and the axial width W _1. When W ₁ ) is 1.6 or more, it is more preferable that 45% or more of each side surface is covered with the fixing member 12 or the sandwiching member 13A. Each side surface of the conveying member 11A, that is, the side surface in contact with the fixing member 12 and the side surface in contact with the sandwiching member 13A may not be covered in the same ratio, but are preferably the same. Similarly, the transport member 11B preferably has 27% or more of each side surface covered by the fixing member 12 or the sandwiching member 13A. When (T ₁ / W ₁ ) is 1.6 or more, each side surface More preferably, 45% or more is covered with the fixing member 12 or the sandwiching member 13A. In other words, it is preferable that 27% or more of each side surface of the conveyance member 11 (rubber member) is covered with the support portion, and when (T ₁ / W ₁ ) is 1.6 or more, 45% or more is included. It is preferable that it is covered with a support part. This is because the surface flare of the roll for separating and conveying paper sheets is reduced and the transportability is excellent.

  Here, the conveying member 11 is made of a rubber elastic body, and is preferably a rubber elastic body made of a rubber base material having a conveying force. The rubber base material is not particularly limited as long as it is a rubber base material conventionally used for a paper sheet separating and conveying roll, and examples thereof include EPDM, nitrile rubber, and polyurethane. Among these, polyurethane is preferable, and caprolactone-based millable polyurethane is particularly preferable. This is because the surface of the roll for separating and transporting paper sheets can be substantially free from the wear and stickiness associated with the wear, and the transport of paper sheets can be carried out stably over a long period of time. A rubber elastic body is a rubber composition obtained by mixing a rubber base material and a conductivity-imparting material added as necessary, and curing and molding the rubber composition. If necessary, a foaming agent, a foaming aid, and vulcanization An agent, a vulcanization accelerator, a filler and the like are mixed and molded.

  The fixing member 12 and the clamping member 13 are each made of resin or metal. Examples of the resin include ABS resin, POM resin, nylon resin, urethane resin, and epoxy resin, and urethane resin is preferable from the viewpoint of strength. Examples of the metal include stainless steel, aluminum, brass, and copper. When the fixing member 12 and the clamping member 13 are made of resin or metal, respectively, the surface deflection of the conveying member 11 can be suppressed when the conveying member 11 rotates in actual use. This is because resin and metal have a small dimensional change due to temperature and can suitably fix the conveying member 11. The fixing member 12 and the clamping member 13 may be made of the same material or different materials, but are preferably made of the same material from the viewpoint of cost.

The rubber member (conveying member 11) preferably has a ratio (T ₁ / W ₁ ) of the radial thickness T1 to the axial width W1 of 0.5 to 2.3, and more preferably 1 0.0-2.0. When T ₁ / W ₁ is 2.3 or less, the flare in the radial direction of the paper sheet separating and conveying roll is reduced, and the conveying property is excellent. When T ₁ / W ₁ is less than 0.5, there is a possibility that the rubber member may be undulated and uneven in the radial direction when the paper sheet is conveyed.

  In addition, the paper sheet separating and conveying roll 10 is preferably one in which the conveying member 11 is moved in the axial direction together with the holding member 13 and the through hole of the conveying member 11 is press-fitted into the convex portion of the fixed member 12. . Specifically, for example, a flat plate member is brought into contact with the clamping member 13 and a predetermined pressure is applied thereto, whereby the conveyance member 11 is slid in the axial direction together with the clamping member 13, and the through hole of the conveyance member 11 is formed. It is preferable that the convex portion of the fixing member 12 is fitted to the above. Thereby, the fixing member 12 and the clamping member 13A and the clamping member 13B are positioned and fixed with respect to the axial direction with high accuracy. Thereby, it can be set as the paper sheet separation conveyance roll which comprises the conveyance member 11 with a uniform tension ratio over the circumferential direction. In the paper sheet separating and conveying roll, radial deflection and horizontal deflection of the conveying member are suppressed during actual use.

In the paper sheet separating and conveying roll 10, the rubber member (conveying member 11) preferably has a tension ratio of 0 to 7% or less, particularly preferably 1 to 6%. If the tension ratio is larger than 7%, the rubber is distorted, and there is a risk that radial flare and surface flare increase. The tension rate here is calculated | required from a following formula.
[Formula 2]

  Moreover, although the roll 10 for paper sheet separation conveyance changes with roll diameters, for example, it is preferable that surface flare is 0.11 mm or less, and it is further more preferable that it is 0.10 mm or less.

  Hereinafter, the manufacturing method of the roll for paper sheet separation conveyance of Embodiment 1 is demonstrated. 4 to 6 are perspective views of the paper sheet separating and conveying roll according to the first embodiment.

  As shown in FIG. 4A, after forming a cylindrical rubber elastic body having a through hole in the center, the conveying member 11A and the conveying member 11B are formed into a ring shape having a predetermined width by cutting off.

  Further, the sandwiching member 13A and the sandwiching member 13B made of a disk-shaped member having the same diameter as the main body portion 12a of the fixing member 12 as shown in FIG. 4B are made of resin or metal. Although the manufacturing method of the clamping member 13 is not specifically limited, For example, it shape | molds by injection.

The conveying member 11B is press-fitted and fitted into the portion 12c. As a result, the tension of the conveying member 11A and the conveying member 11B fitted to the fixed member 12 is uniform over the circumferential direction. This paper sheet separating and conveying roll is free from radial runout and horizontal runout (surface runout) of the carrying member during use.

  Then, as shown in FIG. 6, although not shown, the clamping member 13A and the convex portion 12b of the fixing member 12, and the clamping member 13B and the convex portion 12c of the fixing member 12 are fastened and fixed by bolts. Thus, the clamping member 13A and the fixing member 12, and the fixing member 12 and the clamping member 13B are positioned and fixed with respect to the axial direction.

  Thereafter, although not shown, a shaft is inserted into the central portion of the paper sheet separating and conveying roll 10.

  Finally, if necessary, the sheet separating and conveying roll 10 is set to a predetermined size by polishing the conveying member 11A and the conveying member 11B around the shaft.

  As described above, the paper sheet separating and conveying roll 10 of the first embodiment is inserted into the rubber member (the conveying member 11A and the conveying member 11B) having a predetermined diameter and having a through hole at the center, and the through hole. A core part (convex part 12b, convex part 12c) and a support part which has a diameter larger than the diameter of the core part and smaller than the diameter of the rubber member and sandwiches the rubber member from both sides; By positioning and fixing a member (fixing member 12) having a support portion in close contact with the side surface and a member (holding member 13) having a support portion in close contact with the other side surface of the rubber member in the axial direction, The horizontal deflection (surface flare) of the rubber member is suppressed, and the transportability is excellent.

  Further, the rubber member (conveying member 11A, conveying member 11B) is moved in the axial direction, and the core portion (convex portion 12b, convex portion 12c) is press-fitted into the through hole, thereby further suppressing the horizontal vibration of the rubber member. In addition, the radial flare is suppressed, and a paper sheet separating and conveying roll excellent in conveying properties is obtained.

  In addition, such a paper sheet separating and conveying roll can easily make the rubber member have a predetermined dimensional accuracy. That is, it can be easily manufactured without using a special processing grindstone, and can be manufactured at low cost.

(Test Example 1): Evaluation of surface flare With a pick gauge, the flare width on the side surface of the conveyance member 11 of the roll for separating and conveying paper sheets of each example and each comparative example, that is, the flread width in the horizontal direction was measured. The results are shown in Tables 1-2.

Moreover, the ratio (in the table, each side surface of the conveying member) that is covered with the support portions (fixing members or clamping members) on the respective side surfaces of the conveying member in the paper sheet separating and conveying rolls of each example and each comparative example. Support ratio) (%), the ratio of the thickness T _{1 in} the radial direction of the conveying member to the width W _{1 in} the axial direction (T ₁ / W ₁ ), the crushing rate (%) of the conveying member, and the tension rate of the conveying member ( %) Are shown in Tables 1-4.

(Summary of results)
As shown in Tables 1 to 4, the rolls for separating and conveying the sheets of Examples 1 to 16 are more flexible than the rolls for separating and conveying the sheets of Comparative Examples 1 to 16 in which a conveying member is inserted later. It turned out that there is a tendency to be small. This is considered to be because the horizontal width of the conveying member is varied by manually inserting the conveying member between the fixing member and the clamping member. From this, it was found that the surface deflection can be suppressed by positioning and fixing the fixing member in close contact with the one side surface of the transport member and the gripping member in close contact with the other side surface. It was found that the rolls for separating and transporting paper sheets of Examples 1 to 16 were excellent in transportability because surface flare was suppressed.

  The rolls for separating and conveying paper sheets of Example 2 and Example 7 in which the supporting rate of the side surface of the conveying member is 27% or more have surface flare of 0.08 mm and 0.10 mm, respectively, and the supporting rate is 18%. Surface flare was significantly suppressed as compared with certain Example 8. From this, it was found that when the support rate of the side surface of the conveying member is 27% or more, surface deflection is further suppressed.

The paper sheet separating and conveying roll of Example 10 in which (T ₁ / W ₁ ) is 0.5 and the paper sheet separating and conveying roll in Example 11 in which (T ₁ / W ₁ ) is 2.2 are as follows: In addition, the rolls for separating and conveying paper sheets of Example 9 and (T ₁ / W ₁ ) having surface flares of 0.10 mm and 0.09 mm and (T ₁ / W ₁ ) of 0.3 are 2. 5, the surface deflection was suppressed more than the paper sheet separating and conveying roll of Example 12. _{Further, (T 1} / _W 1) is sheet separation conveying rollers of Examples 4-6 is 2.1-2.3, the surface deflection was below 0.11 mm. From this, it was found that surface flare is further suppressed when (T ₁ / W ₁ ) is 0.5 to 2.3.

  The rolls for separating and conveying the paper sheets of Examples 4 to 6 and Example 14 in which the crushing rate was 0 to 13% were suppressed in surface flare than Example 13 in which the crushing rate was 16%. From this, it was found that surface flaking is further suppressed by setting the crushing rate to 0 to 13%.

  The roll for separating and conveying the paper sheet of Example 7 having a tension ratio of 3% and the roll for separating and conveying the paper sheet of Example 16 having a tension ratio of 7% both have a surface flare of 0.10 mm. Yes, the surface flare was smaller than that of the roll for separating and conveying paper sheets of Example 15 in which the tension rate was 10%. From this, it was found that when the tension ratio is 7% or less, the surface deflection is further suppressed.
