Description of the Related Art Conventionally, a banknote depositing / dispensing machine provided in an automatic teller machine is a deposit / withdrawal unit that serves as a bill insertion / reception port, a discrimination unit that discriminates a denomination or authenticity of a bill, and a bill temporarily. It is comprised by the temporary storage part to accommodate, the several banknote cassette which stores a banknote for every denomination, the conveyance path etc. which connect these.

The conveyance path that connects each part has a branch point, and a switch for switching the conveyance direction is provided at this branch point. The banknote depositing / dispensing machine can control the switching operation of the switching unit to switch the conveyance direction of the banknote at the branch point.

Here, the switch 100 will be described with reference to FIGS. 9A and 9B. As shown in FIG. 9A, the switch 100 includes a shaft 101 that is rotatably supported and orthogonal to a conveyance path (not shown), and a plurality of blade portions 102 (102A to 102C) fixed to the shaft 101. ).

Each of the blade portions 102 (102A to 102C) includes a cylindrical base portion 103 that covers the outer periphery of the shaft 101, and a plurality of blades 104 that protrude from the outer periphery of the base portion 103 at a predetermined interval. Overall, it has a comb-like shape like a fork.

In the switch 100, one end portion of the shaft 101 is connected to the rotation shaft 107 of the drive unit 106 via the coupling 105, and the shaft 101 is rotated as the rotation shaft 107 of the drive unit 106 rotates. Rotate.

Then, the bill depositing / dispensing machine switches the conveyance direction at the branch point by rotating the shaft 101 of the switching device 100 in one direction and the other direction to change the rotation position of the blade portion 102 (102A to 102C).

As shown in FIGS. 9A and 9B, the shaft 101 and the coupling 105 of the switch 100 are fixed by a fixing pin 110, and the coupling 105 and the rotating shaft 107 of the driving unit 106 are fixed by a screw 111. .

Specifically, the shaft 101 of the switch 100 is provided with a pin hole 112 for driving the fixing pin 110 at one end on the coupling 105 side so as to penetrate in a direction perpendicular to the central axis of the shaft 101. Yes.

The coupling 105 has a cylindrical shaft side half portion 105A in which a shaft hole 113 for fitting the shaft 101 is formed along the central axis, and a rotation shaft for fitting the rotation shaft 107 of the drive unit 106. The use hole 114 is configured by a cylindrical rotary shaft side half portion 105B formed along the central axis.

Here, in order to fix the shaft 101 of the switch 100 to the coupling 105, first, one end of the shaft 100 is fitted into the shaft hole 113 of the coupling 105, and the pin hole 112 of the shaft 100 and the shaft side are inserted. The positions of the

pin holes

112 and 115 are aligned so that the pin hole 115 of the half body 105A communicates with each other to form one communication hole.

Then, a fixed pin 110 having a diameter slightly smaller than that of the communication hole and having the same length as that of the communication hole is driven into one communication hole in which the

pin holes

112 and 115 communicate with each other. Thereby, the shaft 101 and the coupling 105 are fixed in a connected state. Such a fixing method using a pin is common and well known (see, for example, Japanese Patent Application Laid-Open No. 11-175803).

In order to fix the coupling 105 to the rotation shaft 107 of the drive unit 106, first, the rotation shaft 107 of the drive unit 106 is fitted into the rotation shaft hole 114 of the coupling 105, and the screw hole 116 of the coupling 105 is inserted.

[1-3. Configuration of switcher]
Next, the configuration of the switch 30 provided at the branch point of the transport path 26 will be described with reference to FIGS. 3 to 5A to 5C. The transport path 26 has a plurality of branch points, and a switch 30 is provided at each of the branch points. Since the basic configuration of the switch 30 is the same, an example is given here. As an example, a description will be given of the switch 30 provided at a branch point located at a connection portion between the conveyance path 26G and the conveyance path 26J.

As shown in FIG. 3, the conveyance path 26G extending in the front-rear direction is formed by a plurality of belts Bt and rollers Rr, and the conveyance path 26J extending in the vertical direction is formed by a plurality of rollers Rr.

Further, a switch 30 for switching the transport direction is provided at a branch point located at a connection portion between the transport path 26G and the transport path 26J.

As shown in FIG. 4 in addition to FIG. 3, the switcher 30 includes a shaft 31 that is rotatably supported and orthogonal to the conveyance paths 26 </ b> G and 26 </ b> J, and a plurality (for example, three) fixed to the shaft 31. ) Blade portion 32 (32A to 32C).

Each of the blade portions 32A to 32C includes a cylindrical base portion 33 that covers the outer periphery of the shaft 31, and a plurality of blades 34 that protrude from the outer periphery of the base portion 33 with a predetermined interval. It has a comb-like shape like a fork.

As shown in FIG. 5A, in the switch 30, one end portion of the shaft 31 is connected to the rotation shaft 37 of the drive unit 36 via the coupling 35, and the rotation shaft 37 of the drive unit 36 rotates. Accordingly, the shaft 31 rotates.

And as shown in FIG. 3, the banknote depositing / withdrawing machine 10 rotates the shaft 31 of the switching device 30 in one direction and the other direction to change the rotation position of the blade portion 32, thereby changing the conveyance direction at the branch point. Switch.

Actually, when the switch 30 is at the rotational position indicated by the solid line in FIG. 3, the conveyance direction at the branching point of the bill BL that is conveyed from the front through the conveyance path 26G is lower (that is, perpendicular to the conveyance path 26G (ie, Direction of the transport path 26J). On the other hand, when in the rotational position indicated by the dotted line in FIG. 3, the conveyance direction at the branching point of the banknote BL conveyed from the front through the conveyance path 26G is the rear along the conveyance path 26G.

Thereby, when the switching device 30 is in the rotation position indicated by the solid line in FIG. 3, the banknote BL conveyed from the front of the branch location through the conveyance path 26G is a conveyance route orthogonal to the conveyance path 26G at the branch location. It is guided to 26J, and is conveyed downward through the conveyance path 26J.

On the other hand, when the switching device 30 is at the rotational position indicated by the dotted line in FIG. 3, the bill BL conveyed from the front of the branch location through the conveyance path 26G passes through the branch location as it is and passes through the conveyance path 26G. It is conveyed backward.

The banknote depositing / dispensing machine 10 switches the conveyance direction of the banknote BL by operating the switch 30 in this way.

Here, the connection mechanism that connects the switch 30, the coupling 35, and the rotation shaft 37 of the drive unit 36 will be described in detail. As shown in FIGS. 5A and 5B, the shaft 31 and the coupling 35 of the switcher 30 are fixed by a cylindrical fixing pin 40, and the coupling 35 and the rotating shaft 37 of the drive unit 36 are fixed by a screw 41. ing.

Specifically, the shaft 31 of the switch 30 is provided with a pin hole 42 for driving the fixing pin 40 at one end on the coupling 35 side so as to penetrate in a direction perpendicular to the central axis of the shaft 31. Yes.

The coupling 35 has a cylindrical shaft side half portion 35A in which a shaft hole 43 for fitting the shaft 31 is formed along the central axis, and a rotation shaft for fitting the rotation shaft 37 of the drive portion 36. The hole 44 is constituted by a cylindrical rotating shaft side half portion 35B formed along the central axis.

A pin hole 45 for driving the fixing pin 40 passes through the shaft side half 35A of the coupling 35 in a direction perpendicular to the central axis through the shaft hole 43 of the shaft side half 35A. Is provided. Further, a screw hole 46 is provided in the rotation shaft side half portion 35B of the coupling 35 so as to pass through the rotation shaft hole 44 of the rotation shaft side half portion 35B and in a direction perpendicular to the central axis. Yes.

A screw hole 47 is provided in the rotating shaft 37 of the driving unit 36 so as to penetrate in a direction orthogonal to the central axis of the rotating shaft 37.

Here, in order to fix the shaft 31 of the switch 30 to the coupling 35, first, one end portion of the shaft 31 is fitted and connected to the shaft hole 43 of the coupling 35, and the pin hole 42 of the shaft 31 is connected. The positions of the pin holes 42 and 45 are adjusted so that the pin hole 45 of the shaft-side half portion 35A communicates with each other to form one communication hole.

Then, a fixed pin 40 having a diameter slightly smaller than the communication hole and having the same length as that of the communication hole is driven into a single communication hole in which the pin holes 42 and 45 communicate with each other. Thereby, the shaft 31 and the coupling 35 are fixed in a connected state.

The pin hole 45 of the coupling 35 may have an outer end portion slightly wider than the other portion, for example, as shown in FIG. The same applies to the pin hole 42 of the shaft 31.

In order to fix the coupling 35 to the rotation shaft 37 of the drive unit 36, first, the rotation shaft 37 of the drive unit 36 is fitted and connected to the rotation shaft hole 44 of the coupling 35, and the screw of the coupling 35 is connected. The positions of the screw holes 46 and 47 are aligned so that the hole 46 and the screw hole 47 of the rotating shaft 37 communicate with each other to form one screw hole.

Then, the screw 41 is inserted while being rotated into one screw hole formed by communicating the screw holes 46 and 47. Thereby, the coupling 35 and the rotating shaft 37 are fixed in a connected state.

By doing so, the shaft 31 of the switch 30 and the rotating shaft 37 of the drive unit 36 are coupled via the coupling 35.

By the way, if the shaft 31 and the coupling 35 of the switching device 30 are simply fixed with the fixing pin 40, as described above, while the switching device 30 is rotated many times in one direction and the other direction, There is a risk that the fixing pin 40 will loosen and fall off.

Therefore, in the present embodiment, as shown in FIG. 5A, of the three blade portions 32A to 32C fixed to the shaft 31, the base portion 33 of the blade portion 32C closest to the coupling 35 is replaced by the coupling 35. The shaft side half body part 35A is extended to cover the mouth of the pin hole 45 of the shaft side half body part 35A in which the fixing pin 40 is inserted by the extension part 33x of the base part 33.

By doing so, as shown in FIG. 5B, the fixing pin 40 is confined inside the extension portion 33 x of the base portion 33, and is fixed and held in the pin holes 42 and 45. Thereby, even if the switch 30 is repeatedly rotated in one direction and the other direction, the fixing pin 40 does not loosen and fall off.

In addition, in the present embodiment, as a manufacturing procedure of the switch 30, the shaft 31 and the coupling 35 are first connected and fixed by the fixing pin 40. Next, the shaft 31 and the coupling 35 fixed by the fixing pin 40 are fixed to the die of the blade portion 32 (32A to 32C), and the resin that becomes the blade portion 32 (32A to 32C) is fixed to the die. The shaft 31, the coupling 35, and the blade portion 32 (32A to 32C) are integrally molded.

By manufacturing the switch 30 in this manner, as shown in FIG. 5B, a gap (backlash) is generated between the pin holes 42 and 45 of the shaft 31 and the coupling 35 and the fixing pin 40 due to manufacturing errors and the like. Even if a gap occurs, the resin that becomes the base portion 33 of the blade portion 32C flows into the gap (back), and the gap (back) is filled with the resin, and is fixed to the pin holes 42 and 45 of the shaft 31 and the coupling 35. The rattling between the pins 40 can be prevented.

[1-4. Summary and Effect]
As described so far, in the banknote depositing / dispensing machine 10, the shaft 31 of the switch 30 is connected to the rotating shaft 37 of the drive unit 36 via the coupling 35. Moreover, in the banknote depositing / dispensing machine 10, the shaft 31 and the coupling 35 of the switch 30 are fixed by the fixing pin 40 inserted in the pin holes 42 and 45 orthogonal to the axial direction.

In addition, in the banknote depositing / dispensing machine 10, the base portion 33 of the blade portion 32C fixed to the shaft 31 of the switch 30 is extended to the coupling 35, and the pin hole 45 of the coupling 35 into which the fixing pin 40 is inserted. To cover. By doing so, the fixing pin 40 is fixedly held in the pin holes 42 and 45, and it can be prevented that the fixing pin 40 loosens and falls off due to the rotation of the shaft 31.

Further, in the banknote depositing / dispensing machine 10, the shaft 31 and the coupling 35 are fixed by the fixing pin 40, and then the resin to be the blade portion 32 (32A to 32C) is poured into the mold and solidified to thereby form the shaft 31. The coupling 35 and the blade portion 32 (32A to 32C) are integrally molded. By doing so, the resin of the blade part 32C flows into the gap (back) between the pin holes 42 and 45 of the shaft 31 and the coupling 35 and the fixing pin 40, and this gap (back) is filled with the resin. The play between the pin holes 42 and 45 of the shaft 31 and the coupling 35 and the fixing pin 40 can be prevented.

Furthermore, by preventing such rattling, the rotation of the rotation shaft 37 of the drive unit 36 can be smoothly transmitted to the shaft 31 and the shaft 31 can be smoothly rotated. In addition, by preventing backlash, the shaft 31 can be prevented from being damaged, and the life of the switch 30 can be increased as compared with the conventional one.

Can be reduced.

[3. Third Embodiment]
Next, a third embodiment will be described. The third embodiment is an embodiment in which the configuration of the connection portion between the switch 30 and the coupling 35 (that is, the configuration of the connection mechanism) is different from the first and second embodiments.

7A and 7B show a configuration of a connection portion between the switch 30 and the coupling 35 according to the third embodiment. In the third embodiment, as in the first embodiment, the shaft 31 and the coupling 35 of the switch 30 are fixed by the fixing pin 60, and the rotation shaft 37 of the coupling 35 and the drive unit 36 is screwed 41.

In addition, in the third embodiment, a hollow fixing pin 60 is used instead of the fixing pin 40. When the shaft 31, the coupling 35, and the blade portion 32 (32A to 32C) are integrally molded, the resin that becomes the blade portion 32C is poured into the fixing pin 60, and the inside of the fixing pin 60 is made of resin. The resin was allowed to solidify in the filled state.

Thereby, the fixing pin 60 is more securely fixed and held in the pin holes 42 and 45. In addition, since the resin that has entered the inside of the fixing pin 60 serves as a cushion, the fixing pin 40 can be prevented from being broken or damaged by a force added when the shaft 31 is rotated.

[4. Other Embodiments]
[4-1. Other Embodiment 1]
In the second embodiment described above, the pin hole 45 of the coupling 35 into which the fixing pin 40 is inserted is covered by the pin drop prevention member 50 provided separately from the blade portion 32.

Here, when the fixing pin 40 is replaced with the hollow fixing pin 60 as in the third embodiment and the pin drop prevention member 50 is molded, the resin that becomes the pin drop prevention member 50 is replaced with the fixing pin 60. The fixing pin 60 may be solidified in a state where the inside of the fixing pin 60 is filled with resin.

Further, in this case, instead of the cylindrical pin removal preventing member 50, as shown in FIGS. 8A and 8B, two disk-shaped

lid portions

70A and 70B having a size capable of covering the pin hole 45 are provided. You may make it use the pin drop prevention member 70 which has.

The pin dropout prevention member 70 includes a resin lid portion 70A that covers one mouth of the pin hole 45 of the coupling 35 and a resin lid portion 70B that covers the other mouth inside the fixing pin 60. It is connected by the resin 70C which has been poured and solidified.

This pin drop prevention member 70 is also formed by pouring the resin that becomes the pin drop prevention member 70 into the fixed pin 60 when the shaft 31, the coupling 35, and the pin drop prevention member 70 are integrally formed.

Such a pin drop prevention member 70 can prevent pin drop and can be molded with a smaller amount of resin as compared with the second embodiment, so that the cost can be further reduced.

[4-2. Other Embodiment 2]
Furthermore, in the above-described first to third embodiments, the application to the coupling mechanism that couples the shaft 31 of the switch 30 and the coupling 35 as the coupling portion has been described. However, the embodiment is not limited to this, and can be applied to a connection mechanism other than the connection mechanism that connects the shaft 31 and the coupling 35 of the switch 30 as long as the connection mechanism connects the shaft and the connecting portion.

For example, as another embodiment, the present invention can be applied to a coupling mechanism that couples a roller shaft and a coupling.

Furthermore, the present invention is not limited to this, and the rotary shaft 37 of the drive unit 36 can be used as a connecting portion, and the rotary shaft 37 can be directly connected to the shaft 31 without using the coupling 35.

In this case, for example, the rotation shaft 37 of the drive unit 36 is made thicker than the shaft 31, a shaft hole is formed on the rotation shaft 37 side, and the shaft 31 is inserted into the shaft hole and fixed by the fixing pin 40. And the shaft 31 is made thicker than the rotation shaft 37 of the drive unit 36, a rotation shaft hole is formed on the shaft 31 side, the rotation shaft 37 is inserted into the rotation shaft hole, and a fixed pin The method of connecting by fixing with 40 is considered.

In either method, as in the first to third embodiments, pin removal can be prevented by providing a member that covers the pin hole into which the fixing pin 40 is inserted.

However, in practice, the banknote depositing and dispensing machine 10 often uses a ready-made drive unit 36, and in this case, it is difficult to process the rotating shaft 37 of the drive unit 36.

Therefore, in this case, of the two connecting methods described above, the shaft 31 is made thicker than the rotation shaft 37 of the drive unit 36, a rotation shaft hole is formed on the shaft 31 side, and the rotation shaft is formed in the rotation shaft hole. A method of connecting by inserting 37 and fixing with the fixing pin 40 is adopted.

On the other hand, the shaft 31 should be as thin as possible within the range that the strength allows in consideration of downsizing of the switch 30 or the like, but when the connecting method of connecting the shaft 31 thicker than the rotating shaft 37 is adopted, It cannot be made thinner than the rotating shaft 37 of the drive unit 36.

Therefore, for example, it is conceivable that only one end portion of the shaft 31 on the rotating shaft side is thicker than the rotating shaft 37 and the shaft 31 is processed so that the other portion is as thin as possible. It will take.

Therefore, when the drive unit 36 is an off-the-shelf product and the shaft 31 is desired to be as thin as possible, the shaft 31 and the rotary shaft 37 of the drive unit 36 are arranged as in the first to third embodiments described above. It is realistic and desirable that the coupling 35 is interposed.

The shaft and the coupling 35 are integrally molded so as to be poured into a gap (backlash) between 42 and 45 and the fixing pin 40.

However, the embodiment is not limited to this, and the pin drop prevention member 50 may not be integrally formed with the shaft 31 and the coupling 35. For example, a cylindrical pin drop prevention member (not shown) having an inner diameter slightly smaller than the outer diameter of the shaft side half portion 35A of the coupling 35 is separately molded from resin and fixed to the coupling 35. It may be inserted from the other end portion side of the shaft 31 and fitted into a position covering the pin hole 45 of the coupling 35.

Further, the pin drop prevention member is not limited to resin and may be made of other materials such as metal. The same applies to the blade portion 32 of the switch 30.
