Description

The right-hand member of the right-hand carriage for conveying paper sheets

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a right-wing member (wing member) of a right-wing car for conveying a paper sheet (paper wheel transporting wing car) used for conveying paper sheets.

Automatic teller machine, automatic teller machine, change machine, automatic teller machine, etc. are provided with a conveying device for conveying paper sheets, such as banknotes, magnetic cards, tables and the like. In the conveying apparatus, a right-hand carriage for conveying paper sheets is used. A right-hand carriage for conveying a paper sheet is constituted by mounting a plurality of right-handed members radially in a radial direction perpendicular to the rotational axis of a rotatable cylindrical member. Then, the right-handed car for conveying the paper sheet rotates the right-handed member at a high speed to make contact with the paper sheets, and transports the paper sheets by the frictional force at the time of contact.

Since the right-wing members come into contact with paper sheets, plastic deformation occurs due to use for a long period of time, and damage such as abrasion, cracking, cracking, and the like occurs. As the right-handed member undergoes plastic deformation, the contact with the paper sheets becomes insufficient, leading to the cause of conveyance mistakes and the like. Here, a structure has been proposed in which the right-hand member is attached to the cylindrical member by attaching / detaching, and the right-hand member is replaceable. In short, it is required that the right-handed member is capable of suppressing plastic deformation and improving bending durability.

Here, in order to suppress the plastic deformation of the right-handed member and to improve the bending durability, Japanese Unexamined Patent Publication (Kokai) No. H07-338861 proposes a thermosetting urethane formed by a mold and a right-hand member using aramid twisted yarn at the core wire. Patent Document 2 proposes a right-handed member made of a thermosetting polyurethane and a core wire made of nylon. However, even in the right-handed members shown in Patent Documents 1 and 2, the bending durability was not sufficiently satisfied. In order to suppress the plastic deformation of the right-handed member, it is required to have flexibility capable of bending while maintaining the strength by increasing the bending durability. In short, the right-handed member is required to be a plastic-deformed baby, that is, a restorability capable of returning to its original shape while improving bending durability.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a right-handed member of a right-handed car for conveying a paper sheet which suppresses plastic deformation and has improved bending durability and restoration.

In order to solve the above problems, a right-hand member of a right-hand carriage for conveying a paper sheet according to the present invention comprises at least one right-hand member of a right-hand carriage for conveying a paper sheet, And at least a part thereof is buried in the inside of the right leg member main body and is arranged in a plurality of rows in the axial direction of the rotating shaft of the tubular member And a core wire.

In this configuration, at least one right-hand member of the right-hand carriage for conveying the paper sheet is disposed so as to protrude from the outer peripheral surface of the rotatable cylindrical member. The right-hand member of the right-hand carriage for conveying the paper sheet may be conveyed in contact with the paper sheet. The right-hand member of the right-hand carriage for conveying the paper sheet has a right-hand member main body and a core wire. The right-wing member main body is made of a thermosetting polyurethane elastomer. The core wire is made of polyester fiber. At least a part of the core wire is buried in the inside of the right-hand member main body. In addition, a plurality of core wires are arranged side by side in the axial direction of the rotation shaft of the cylinder member.

An elastomer material excellent in elasticity is preferable for the right-wing member main body from the viewpoint of restitution property, and in particular, the thermosetting polyurethane elastomer among the elastomeric materials is excellent in abrasion resistance and elasticity. In addition, the polyester fiber forming the core wire has excellent heat resistance and strength. From the viewpoint of bending durability, polyester fibers, aramid fibers and nylon fibers are preferable for core wire, and polyester fibers which are hard to buckle against plastic deformation are particularly suitable. Since the right-and-left member main body is made of a thermosetting polyurethane elastomer and the core wire is made of polyester fiber, it is possible to reduce the deformation force (compressive force) generated in the core wire at the time of bending and to improve the bending durability and restoration of the right- do. In short, the right-handed member of the right-handed carriage for conveying paper of the present invention can suppress the plastic deformation and improve the bending durability and the stability.

According to another aspect, it is preferable that the right-handed member of the right-hand carriage for conveying the paper sheet of the present invention has the following configuration.

The fineness of the core wire is in the range of 100 to 300 denier. Alternatively, the fineness of the core wires ranges from 120 to 180 denier.

In this configuration, the fineness of the core wire is preferably in the range of 100 to 300 denier. It is preferable that the diameter (core diameter) of the core wire is in the range of 0.10 to 0.19 mm. Further, the fineness of the core wire is more preferably in the range of 120 to 180 denier. In short, the diameter of the core wire is relatively small. When the diameter of the core wire is large, the deformation force (compressive force) inside the core wire (particularly around the outer periphery of the right-hand carriage for conveying the paper sheet) is increased and the buckling and breakage are likely to occur do. Accordingly, by reducing the diameter of the core wire relatively, the deformation force (compressive force) generated inside the core wire at the time of bending can be reduced, and the bending durability is improved. In short, the right-handed member of the right-handed car for conveying paper of this configuration can suppress the plastic deformation, and can further improve the bending durability and the stability.

According to another aspect, it is preferable that the right-handed member of the right-hand carriage for conveying the paper sheet of the present invention has the following configuration.

The right-wing member main body is made of a thermosetting polyurethane elastomer including a plasticizer.

Alternatively, the right-hand member main body is made of a thermosetting polyurethane elastomer containing a plasticizer, and the plasticizer is 20 parts by mass or less based on 100 parts by mass of the thermosetting polyurethane elastomer. Alternatively, the right-hand member main body is made of a thermosetting polyurethane elastomer containing a plasticizer, and the plasticizer is 5 parts by mass or less based on 100 parts by mass of the thermosetting polyurethane elastomer.

In this configuration, the right-hand member main body is made of a thermosetting polyurethane elastomer containing a plasticizer, and the plasticizer is preferably 20 parts by mass or less based on 100 parts by mass of the thermosetting polyurethane elastomer. Further, the right-hand member main body is made of a thermosetting polyurethane elastomer containing a plasticizer, and the plasticizer is more preferably 5 parts by mass or less based on 100 parts by mass of the thermosetting polyurethane elastomer. Further, it is more preferable that the right-wing member main body is made of a thermosetting polyurethane elastomer not containing a plasticizer. Here, when the right-wing member main body contains a large amount of plasticizer, the plasticizer is exuded while repeatedly contacting the right-side member main body in the long-time use, and shifts to the surface of the paper sheet. As a result, the right-side member main body in contact with the paper sheets is plastically deformed, and warpage of the right-side member occurs. Here, by reducing the amount of the plasticizer contained in the right-side member main body or by not including the plasticizer in the right-side member main body, warping of the right-side member is relatively reduced and restoration force is improved. In short, the right-handed member of the right-handed car for conveying paper of this configuration can suppress the plastic deformation, and can further improve the bending durability and the stability.

According to another aspect, it is preferable that the right-handed member of the right-hand carriage for conveying the paper sheet of the present invention has the following configuration.

The core wires are arranged in parallel to each other in the axial direction of the rotation axis so that the intervals of the core wires adjacent to each other are in a range of 0.25 to 0.50 mm. Alternatively, a plurality of the core wires are arranged in parallel in the axial direction of the rotation shaft so that the intervals of the core wires adjacent to each other are in the range of 0.25 to 0.30 mm.

In this configuration, it is preferable that the core wires are arranged in parallel in the axial direction of the rotation axis so that the interval of the core wires adjacent to each other is in the range of 0.25 to 0.50 mm. Alternatively, it is more preferable that the core wires are arranged in parallel in the axial direction of the rotating shaft so that the intervals of the adjacent core wires are in the range of 0.25 to 0.30 mm. When the distance between adjacent core wires is less than 0.25 mm, the number of core wires buried in the right-side member main body becomes large. Then, the rigidity of the right-handed member becomes large, and the flexibility of the right-handed member is reduced. When the distance between the adjacent core wires exceeds 0.50 mm (particularly, 0.30 mm), the number of core wires buried in the right-side member main body decreases. There is a possibility that it is not possible to sufficiently reduce the deformation force generated inside the core wire at the time of bending. Therefore, when the distance between the adjacent core wires is in the range of 0.25 to 0.50 mm (in particular, in the range of 0.25 to 0.30 mm), it is possible to properly maintain the flexibility of the right-handed member. In short, the right-handed member of the right-handed car for conveying paper of this configuration can suppress the plastic deformation, and can further improve the bending durability and the stability.

According to another aspect, it is preferable that the right-handed member of the right-hand carriage for conveying the paper sheet of the present invention has the following configuration.

The right-handed member is disposed so as to protrude from the outer peripheral surface of the cylindrical member along a radial direction perpendicular to the axial direction of the rotation shaft of the cylindrical member, and the core wire is embedded along the radial direction of the rotation shaft of the cylindrical member.

Here, the term " along the radial direction " is not limited to mean parallel to the radial direction. The term " along the radial direction " includes a case of being curved in the radial direction or a case of being inclined at a predetermined angle with respect to a straight line indicating the radial direction.

INDUSTRIAL APPLICABILITY As described above, according to the present invention, it is possible to provide a right-handed member of a right-handed car for conveying a paper sheet, which suppresses plastic deformation and has enhanced bending durability and restoration.

In addition, the cylindrical member 10 may not have the shaft hole 13. That is, the rotary shaft 11 may be integrally formed with the base 12. As described above, the cylindrical member 10 is rotatably formed. That is, the cylindrical member 10 is configured to rotate as the rotary shaft 11 rotates.

The notched portion 14 is formed to open on the upper surface 12a. The cutout portion 14 is formed so as to open on the outer circumferential surface 12c at an upper portion of the outer circumferential surface 12c. The upper portion of the outer circumferential surface 12c is a portion closer to the upper surface 12a than the bottom surface 12b of the outer circumferential surface 12c.

An elastomer material having excellent elasticity is preferable for the right-wing member main body 21 from the viewpoint of restitution property, and in particular, a thermosetting polyurethane elastomer among elastomer materials is excellent in abrasion resistance and elasticity. The polyester fiber forming the core wire 25 is excellent in heat resistance and strength. From the viewpoint of bending durability, polyester fibers, aramid fibers and nylon fibers are preferable for the core wire 25, and polyester fibers which are hard to buckle against plastic deformation are suitable.

Since the right-wing member main body 21 is made of a thermosetting polyurethane elastomer and the core wire 25 is made of polyester fiber, it is possible to reduce the deformation force (compressive force) generated in the core wire 25 at the time of bending, The bending durability and resilience of the right-handed member 20 is improved. In short, it is possible to suppress the plastic deformation of the right-hand member 20 of the right-hand autoclave 1 for conveying paper of the present invention, thereby improving the bending durability and the restoring property.

It should be noted that the fineness of the core wire 25 in the right-hand member 20 of the right-hand carriage 1 for conveying paper of the present embodiment is in the range of 100 to 300 denier. In this case, the diameter of the core wire 25 is preferably in the range of 0.10 to 0.19 mm. Furthermore, the fineness of the core wire 25 is more preferably in the range of 120 to 180 denier. That is, the diameter of the core wire 25 is relatively small. In the case where the diameter of the core wire 25 is large, the deformation force (compressive force) inside the core wire 25 (near the outer circumferential portion) is increased when the diameter of the core wire 25 is small, It becomes easy. Therefore, by making the diameter of the core wire 25 relatively thin, the deformation force (compressive force) generated inside the core wire 25 at the time of bending can be reduced, and the bending durability and the restored phase are improved. In short, the right-handed member 20 of the right-hand autoclave 1 for paper transport of this configuration can suppress the plastic deformation, and can further improve the bending durability and the stability.

In the right-hand member 20 of the right-hand car 1 of the embodiment of the present invention, the right-hand member main body 21 is made of a thermosetting polyurethane elastomer containing a plasticizer, and the plasticizer is a thermosetting polyurethane It is preferably 20 parts by mass or less based on 100 parts by mass of the elastomer. The right-wing member main body 21 is made of a thermosetting polyurethane elastomer containing a plasticizer, and the plasticizer is more preferably 5 parts by mass or less based on 100 parts by mass of the thermosetting polyurethane elastomer. Moreover, the right-wing member main body 21 is preferably made of a thermosetting polyurethane elastomer not containing a plasticizer. Here, when the right-wing member main body 21 contains a large amount of plasticizer, the plasticizer is spouted out during repeated contact of the right-wing member main body 21 with the paper sheets during long- . As a result, the right-wing main body 21 in contact with the paper sheets is plastically deformed, and warpage of the right-wing member 20 occurs. Here, by reducing the amount of the plasticizer contained in the right-hand member main body 21 or by not including the plasticizer in the right-hand member main body 21, the warping of the right-hand member 20 is relatively reduced and the restoring force is improved . In short, the right-handed member 20 of the right-hand autoclave 1 for paper transport of this configuration can suppress the plastic deformation, and can further improve the bending durability and the stability.

Further, the fact that the thermosetting polyurethane elastomer does not include a plasticizer means that the plasticizer is substantially not contained in the thermosetting polyurethane elastomer. Here, the expression " substantially not included " means that it is allowed to include it as an impurity, but not intentionally.

In the right-hand member 20 of the right-hand drive car 1 for transporting paper sheets according to the present embodiment, the core wire 25 is formed such that the distance between the adjacent core wires 25 is in the range of 0.25 to 0.50 mm, It is preferable to arrange a plurality of them in parallel in the axial direction of the main body 11. It is more preferable that a plurality of the core wires 25 are arranged side by side in the axial direction of the rotating shaft 11 so that the distance between the adjacent core wires 25 is in the range of 0.25 to 0.30 mm. When the distance 25 between adjacent core wires is less than 0.25 mm, the number of core wires 25 buried in the right-side body 21 increases. Then, the rigidity of the right-handed member 20 is increased, and the bending property of the right-handed member 20 is reduced. When the distance between adjacent core wires 25 exceeds 0.50 mm (particularly 0.30 mm), the number of core wires 25 buried in the right-side body 21 becomes small. There is a possibility that it is not possible to sufficiently reduce the deformation force generated inside the core wire 25 at the time of bending. Therefore, when the distance between the adjacent core wires 25 is in the range of 0.25 to 0.50 mm (particularly in the range of 0.25 to 0.30 mm), it is possible to maintain the flexibility of the right-handed member 20 properly. In short, the right-handed member 20 of the right-hand autoclave 1 for paper transport of this configuration can suppress the plastic deformation, and can further improve the bending durability and the stability.

The cylindrical member 10 does not need to have the shaft hole 13 for inserting the rotary shaft 11. In short, the cylindrical member 10 may be formed integrally with the rotary shaft 11 and the base portion 12. [

The bending durability test and the stability test were performed on the right-handed member 20 of the right-handed car for conveying the paper of the embodiment and the right-handed member 120 of the paper-

The bending durability test was performed on the right-handed member 20 of the right-handed car for conveying the paper sheets of Examples 1 to 9 and the right-handed member 120 of the paper- In the bending durability test, a testing apparatus 30 as shown in Fig. 4 was used. The bending durability test apparatus 30 is connected to the slide base 32 of the stainless steel plate and the motor 31 via the bar 33. [ The bending durability test apparatus 30 is configured such that the rotation of the motor 31 causes the slide base 32 attached to the bar 33 to move in the order of the arrows shown in Figs.4A and 4B And is configured to reciprocate. Then, the right-handed member 20 of the right-hand carriage of the embodiment of the embodiment and the right-hand member 120 of the right-hand carriage of the comparative example are attached to the fixing member 35. The right-handed member 20 of the right-hand drive car of the embodiment of the embodiment and the right-hand member 120 of the right-hand drive car of the comparative example are in contact with the slide base 32, 4 (a) and 4 (b). By using this test apparatus 30, the right-handed member 20 of the right-handed carriage for conveying the paper of Examples 1 to 9 and the right-handed member 120 of the right-handed carriage for conveying paper of Comparative Examples 1 to 9, One reciprocating motion was performed at one bend, and the reciprocating motion was performed at a speed of 300 bends / minute. Then, when the right-handed member 20 of the right-handed car for conveying the paper of the embodiment and the right-handed member 120 of the right-handed car for conveying the paper of the comparative example in the example after about 170,000 bending and about 170- .

Table 1 shows the test results of the bending durability test of the right-hand member 20 of the right-hand car for conveying the paper of Examples 1 to 9. Table 2 shows the results of the bending durability test of the right-hand member 120 of the right-hand drive for conveying the paper of Comparative Examples 1 to 9. In the bending durability test, the ratio of the reduction of the length of the right-hand member of the right-handed car for conveying the paper sheet and the state of plastic deformation of the right-hand member of the paper- And the presence of plastic deformation of the right-hand member of the right-handed car was determined. In the bending durability test, the length from the center of the cylindrical member 10 in the radial direction perpendicular to the axial direction G of the rotating shaft 11 of the cylindrical member 10 before the bending durability test to the tip of the right- L11 and the apparent length L12 from the center of the cylindrical member 10 to the tip of the right leg member 20 in the radial direction perpendicular to the axial direction of the rotational shaft 11 of the cylindrical member 10 after the bending durability test . Then, the ratio of the difference between the lengths of L11 and L12 was measured as a ratio of the reduction of the length of the right-side member. In the case where there is no decrease in the length of the right-hand member of the right-hand carriage for paper transportation, the plastic deformation is determined to be zero. When the reduction of the length of the right-hand member of the right-handed car for conveying the paper sheet is less than 2% and the state of plastic deformation is curved, the degree of plastic deformation of the right-hand member of the paper- The degree of plastic deformation of the right-hand member of the right-hand side carriage for paper transportation was determined to be B when the reduction of the length of the right-hand member of the right-hand carriage for paper transportation was less than 2% and the state of plastic deformation was refraction. The degree of plastic deformation of the right-hand member of the right-handed vehicle for conveying the paper sheets was judged as C when the reduction of the length of the right-hand member of the right-handed car for conveying the paper sheet was 2% or more and the state of plastic deformation was bending or refraction . The overall evaluation of the bending durability of the right-hand member of the right-hand carriage for paper transportation was determined as follows. In the case where the right-hand member of the right-hand carriage for conveying the paper sheet is not broken or plastically deformed, When the right-hand member of the right-hand carriage for conveying the paper sheet was not broken, but slightly plastic deformation was present, it was O. When the right-hand member of the right-hand carriage for conveying the paper sheet is broken, but the degree of the problem is practically usable, it is?. X was taken when the right-hand member of the right-hand drive for transporting the paper sheet was broken and the breakage was not practically usable.

As shown in Tables 1 and 2, the right-handed member 20 of the right-handed carriage for conveying the paper of Examples 1 to 9, which is a combination of "polyurethane + polyester" The evaluation was ⓞ, O, Δ. In the case of the right-handed member 120 of the right-handed carriage for conveying the paper of Comparative Examples 1 to 9 in which the combination of the material of the main body and the material of the core wire was a combination other than "polyurethane + polyester" In short, the right-handed member 20 of the right-handed carriage for conveying the paper of Examples 1 to 9, in which the combination of the material of the main body and the material of the core wire is a combination of "polyurethane + polyester" It was confirmed that bending durability was superior to that of the right side member 120 of the right side carriage for conveying the paper of.

In addition, the fineness of the core wire was varied in the right-hand member 20 of the right-handed car for conveying the paper of Examples 1 to 9, and the superiority was compared. Comparing the right-handed members 20 of the right-handed car for conveying the paper of Examples 1, 2, 3, 6, and 7 in which the fineness of the core wire was varied, in Examples 1, 2, It is confirmed that the overall evaluation of the right-hand member 20 of the right-handed car for conveying the paper sheets of 3 is ⓞ or O and that the bending durability of the right-hand member 20 of the paper- there was. Since the right-hand member 20 of the right-handed car for conveying the paper of the sixth embodiment is extremely fine with a fineness of 90 deniers of the core wire, rigidity of the right-hand member 20 can not be maintained and is easily broken, It is considered that cracks have occurred. It is considered that the right-handed member 20 of the right-handed car for conveying the paper of the seventh embodiment has a large deformation force in the core wire at the time of bending and a buckling of the core wire because the core wire is thick at 450 denier. In addition, the right-hand member 20 of the right-hand drive for conveying the paper of Example 7 has a thick core wire and a core wire with a period of 0.3 mm. In other words, it was confirmed that when the fineness of the core wire of the right-handed member is reduced, the breakage and plastic deformation are further suppressed.

In addition, among the right-handed members 20 of the right-hand carts for conveying the paper of Examples 1 to 9, the cycle of the core wire was varied and the superiority was compared. Comparing the right-handed members 20 of the right-handed carts for conveying the paper of Examples 1, 4, 5, 8, and 9 in which the periods of the core wires were varied, the results of Examples 1, 4, It is confirmed that the overall evaluation of the right-hand member 20 of the right-handed carriage for conveying the paper sheets is 5 or 0 and the flexural durability is superior to that of the right-hand member 20 of the paper- there was. It is considered that the right-hand member 20 of the right-handed car for conveying the paper of the eighth embodiment has a core wire of 0.2 mm in densification and the bendability of the right-hand member is reduced. Since the right-hand member 20 of the right-handed car for conveying the paper of Example 9 has a widened core wire period of 0.7 mm, the rigidity of the right-handed member can not be maintained and is easily broken, I think. In other words, it was confirmed that when the period of the core wire of the right-handed member is made small, the breakage and the plastic deformation are further suppressed.

In the stability test, the addition amount of the plasticizer was varied to confirm the difference in stability. The stability test was carried out on the right-handed member 20 of the right-handed carriage for conveying the paper sheets of each of Examples 1, 2, 3, 5, and 10 to 15. In the stability test, a test apparatus 40 as shown in Fig. 5 (a) was used. The test apparatus 40 for the stability test is configured to have a motor (not shown). The test apparatus 40 of the stability test is mounted with four right-handed members 20 of the right-handed carriage for conveying the paper sheets according to the first and third embodiments on the cylindrical member 10 rotatably attached to the motor. In the stability test, the right-handed car 1 for conveying the paper sheets of each of Examples 1, 2, 3, 5, and 10 to 15 was rotated at 1000 rpm, and the paper sheets of Examples 1, 2, 3, 5, The right-handed member 20 of the right-handed carriage for flow conveyance is connected to the ordinary paper 41 and brought into contact therewith. 5 (b) is a schematic view showing the shape of the right-hand member 20 before the stability test, and FIG. 5 (c) is a schematic view showing the shape of the right- The length from the center of the cylindrical member 10 to the front end of the right leg member 20 in the radial direction perpendicular to the axial direction G of the rotating shaft 11 of the cylindrical member 10 before the stability test is L1 The apparent length from the center of the cylindrical member 10 to the tip of the right leg member 20 in the radial direction perpendicular to the axial direction of the rotary shaft 11 of the cylindrical member 10 after the stability test is represented by L2 do. Then, the ratio of the difference between the lengths of L1 and L2 was measured as the reduction rate of the tip of the right-wing member (hereinafter referred to as " right-wing member leading end reduction ratio "). Table 3 shows the reduction rates of the right-wing members in the stability tests performed for Examples 1, 2, 3, 5, and 10 to 15, respectively. Table 3 shows the results of the flexural durability test and the stability test.

Fig. 6 shows test results of the restoration test for the right-hand member 20 of the right-hand drive carriage for conveying the paper of Example 1 and Example 12. Fig. Here, the number of passes shown in Fig. 6 is the number of times that the right-handed member 20 contacts ordinary paper. In Fig. 6, the average value of the four right-handed members is shown in the graph as the right-hand member leading end reduction ratio. As shown in Fig. 6, as the number of passes increases, the leading end member leading end decreasing rate becomes larger. This is because the right-wing member 20, which was initially straight, is bent in one direction by plastic deformation (bending deformation) into an arch shape due to abrasion of the tip of the right-wing member 20 and the bending deformation gradually becomes larger Because. Here, the improvement of the restoring force means that the force to return to the original straight shape after the bending deformation increases. That is, the difference between the length before the stability test and the length of the right-hand member 20 after the test becomes small. Therefore, from the test results of the stability test shown in Fig. 6, it can be understood that the right-wing member 20 to which the plasticizer of Example 12 is not added has a smaller tip end reduction ratio of the right wing member 20 to which the plasticizer of Example 1 is added It is understood. From the above, it was confirmed that the restorative force of the right-wing member 20 to which the plasticizer of Example 12 was not added was higher than that of the right-wing member 20 of Example 1. [

As shown in Table 3, the ratio of the right-hand member leading end reduction rate at the time of 50,000,000 passes in each of the measured examples is 2.3% for the right-hand member 20 of the right- The right side member 20 of the right side carriage for sheet conveyance was 1.9%, the right side member 20 of the right side carriage for conveying the sheet of Example 11 was 1.7%, the right side member of the right side carriage for conveying the paper of Example 12 20) was 1.4%. As a result, it can be seen that as the plasticizer is reduced, the tip reduction rate is lowered and the stability is improved while maintaining the bending durability. Likewise, the right-handed member 20 of the right-handed carriage for conveying the paper of Examples 2, 3 and 5, in which the core wires had different degrees of island cycle, It can be seen that, in comparison with the right-handed member 20 of the right-wing car, the tip reduction rate is lowered and the stability is improved.

As described above, according to the examples and the comparative examples of the present invention, the right-side member main body of the right-hand member of the right-hand side of the paper sheet transportation is less likely to undergo plastic deformation than the hydrogenated nitrile rubber (H-NBR) in the thermosetting polyurethane elastomer , It is possible to increase the bending durability. In the case where the right-hand member main body of the right-hand member of the right-hand carriage for paper sheet transportation is made of a thermosetting polyurethane elastomer, the following has been understood. It has been understood that the core wire of the right-handed member can increase the bending durability if it is a polyester fiber, not a nylon fiber or an aramid fiber. It has been understood that the period of the core wire of the right-handed member is 0.25 mm, 0.3 mm or 0.5 mm rather than 0.2 mm or 0.7 mm, which is less likely to undergo plastic deformation and can be improved in bending durability. Moreover, it has been understood that the period of the core wire of the right-handed member is 0.25 mm or 0.3 mm longer than 0.5 mm, which is less likely to be plastic-deformed and capable of improving bending durability. It has been understood that the fineness of the core wire of the right-handed member is not more than 90 denier or 450 denier, and 100 denier, 150 denier and 300 denier are less likely to be plastic-deformed and bend durability can be improved. Moreover, it has been understood that the fineness of the core wire of the right-handed member is not more than 100 denier or 300 denier and 150 denier, and it is possible to increase the durability. The right-side member main body may contain a plasticizer in the thermosetting polyurethane elastomer. However, it is understood that the upper limit of the amount is preferably 20 parts by weight per 100 parts by weight of the thermosetting polyurethane elastomer. Furthermore, it has been understood that the right-wing member main body is improved in restoring force when a thermosetting polyurethane elastomer is not contained in the plasticizer.

Therefore, it is possible to suppress the plastic deformation and increase the bending durability if the right-hand member of the right-handed car for paper transportation is a thermosetting polyurethane elastomer not containing a plasticizer and the core wire of the right- . Further, in order to enhance the bending durability, the core wire has a fineness of 100 to 300 denier (more preferably, 120 to 180 denier) and a core wire period of 0.25 to 0.50 mm (more preferably 0.25 to 0.50 mm) 0.30 mm).

The present application is based on Japanese Patent Application No. 2016-232864, filed on November 30, 2016, and Japanese Patent Application No. 2017-226925, filed November 27, 2017, the contents of which are incorporated herein by reference.

By using the present invention, it is possible to provide a right-handed member of a right-handed car for conveying a paper sheet, which suppresses plastic deformation and has enhanced bending durability.
