As shown in FIGS. 1 and 5, the coin transport mechanism includes an endless belt 332, a pulley 331, and a motor (not shown).

When the shutter 342 is opened by the solenoid 341, the coin K falls from the transport passage 33 and is stored in the first chamber 1Aa of the coin storage / withdrawal device 1A.

[Explanation of the transport mechanism of the hopper 32]
The hopper 32 will be described with reference to FIGS. 2 and 3 (a) to 6. FIG. 2 is a perspective view showing a part of the configuration of the coin transport device 30. FIG. 3A is a diagram showing a state in which coin K is flowing backward. FIG. 3B is a diagram showing a state in which the coin K has slipped through. FIG. 4 is a plan sectional view showing the configuration of the change deposit / withdrawal machine 100. FIG. 5 is a cross-sectional view showing the configuration of the hopper 32 and the transport passage 33. FIG. 6 is a cross-sectional view showing the configuration of the transport passage 33.

As shown in FIGS. 2, 4, and 5, the hopper 32 has a rotating disk-shaped passage. The coin K is conveyed into the hopper 32 from the transfer passage 311 or the transfer passage 312 by the endless belt. The hopper 32 rotates the coin K clockwise by the rotating plate 321 provided at the bottom of the passage and conveys the coin K to the pair of conveying rollers 351 and the conveying roller 352.

More specifically, the coin K conveyed in the hopper 32 moves toward the peripheral wall portion 322 by receiving centrifugal force when it is rotated clockwise by the rotating plate 321.

The rotating plate 321 is provided with a plurality of small holes, and the rotation speed is adjusted because the coin K is rotated clockwise at high speed and moved to the peripheral wall portion 322 by centrifugal force.

The peripheral wall portion 322 is formed in an annular shape. The peripheral wall portion 322 is provided with a discharge port 323 for discharging coins K. A rotating plate 321 is provided below the peripheral wall portion 322.

The coin K rotated by the rotating plate 321 receives centrifugal force and is discharged from the discharge port 323 toward the pair of transport rollers 351 and 352. The discharge port 323 is a gap formed between the edge portion of the rotating plate 321 and the lower end portion of the peripheral wall portion 322.

The coin K discharged from the discharge port 323 is sandwiched between the pair of transport rollers 351 and the transport rollers 352 and carried into the transport passage 33 at a transport speed Vr.

The coin K is driven by the transport roller 351 and the transport roller 352 follows the movement of the coin K. Both the transfer roller 351 and the transfer roller 352 may be driven.

The transfer roller 352 is pressed against the transfer roller 351 by a leaf spring (not shown). When the coin K is inserted between the pair of transfer rollers 351 and the transfer roller 352, the thickness of the coin K causes the transfer roller 352 to be pushed away from the transfer roller 351 against the urging force of the leaf spring.

The transport speed Vc of the endless belt 332 is larger than the transport speed Vr in the transport direction X by the transport rollers 351 and the transport rollers 352 (Vc> Vr).

By doing so, the adjacent coins K1 and K2 are appropriately spaced to prevent the coins K1 and K2 from approaching each other, and the coin identification unit 20 facilitates the identification of the coins K1 and K2. ..

Further, by avoiding the collision of the coin K1 with the coin K2 due to slipping through, the backflow of the coin K1 can be prevented.

As shown in FIGS. 5 and 6, the coin K carried into the transport passage 33 is placed on the first chamber 1Aa of the coin storage / withdrawal device 1A via two endless belts 332 combined up and down. It is carried to and stored in the corresponding room.

In order to increase the processing speed of the coin K, it is desirable to increase the rotation speed of the rotary plate 321. However, when the rotation speed of the rotary plate 321 is increased, the coin K is directed toward the transfer roller 351 and the transfer roller 352 by centrifugal force. The sliding transport speed Vb also increases.

However, when the momentum (momentum) of the coin K sliding toward the transport roller 351 and the transport roller 352 increases and the coin K vigorously collides with the transport roller 351 and the transport roller 352, the coin K vigorously collides with the transport roller 351 and the transport roller 352. Coin K may be bounced off without engaging.

In particular, when the drive mechanism of the transport roller 352 cannot be provided due to space limitations, the transport roller 352 only follows the movement of the coin K and cannot directly pull in the coin K.

As a result, as shown in FIG. 3A, the coin K may not mesh with the transport roller 352 and may hit the edge of the transport roller 352 and be bounced off, so that the backflow of the coin K is likely to occur.

Further, a thick coin K such as a 500-yen coin is not only difficult to be pinched by the transport roller 351 and the transport roller 352, but is also separately being transported in front of the transport roller 351 and the transport roller 352 and the coin K by centrifugal force. Since the momentum of sliding toward the coin is large, the backflow of the coin K at the time of such a collision is particularly likely to occur.

Here, if the rotational speed of the rotating plate 321 is reduced to reduce the centrifugal force generated in the coin K, the transport speed Vb at which the coin K slides toward the transport roller 351 and the transport roller 352 also decreases, and the coin K is transported. It is possible to ensure that the rollers 351 and the transfer rollers 352 mesh with each other.

However, if the rotation speed of the rotating plate 321 is lowered, the processing speed of the coin K becomes slow.

On the other hand, as shown in FIG. 3B, by widening the distance between the transfer roller 351 and the transfer roller 352, a thick coin K such as a 500-yen coin also meshes between the transfer roller 351 and the transfer roller 352. It can be made easier.

However, when the distance between the transfer roller 351 and the transfer roller 352 is widened, a thin coin K1 such as a 1-yen coin may vigorously slide between the transfer roller 351 and the transfer roller 352 and slip through.

When such a slip-through of the coin K1 occurs, the coin K1 may approach another coin K2 being transported in the transport passage 33. When the coins K1 and K2 are close to each other in the coin identification unit 20, it becomes difficult to identify them. Therefore, the coins K1 and K2 may not be properly distributed to the coin storage chamber according to the type. is there.

Since the conditions under which backflow and proximity of coin K occur greatly differ depending on the thickness of coin K, the thickness from 1-yen coin to 500-yen coin can be adjusted by simply adjusting the distance between the transport roller 351 and the transport roller 352. It was difficult to prevent backflow and proximity to all coins K with different values.

Under these circumstances, the impact of the collision of the coin K with the transport roller 351 and the transport roller 352 without reducing the rotation speed of the rotating plate 321 or widening the distance between the transport roller 351 and the transport roller 352, or There has been a demand for a new mechanism for alleviating the impact caused by a collision with another coin being carried in front of the coin K and preventing the backflow of the coin K due to these collisions.

[Structure of sheet 37]
Next, the coin transfer device 30 will be further described with reference to FIGS. 7 to 9. 7 and 9 are plan views showing the coin transport device 30. FIG. 8 is a perspective view showing the coin transport device 30.

As shown in FIGS. 7 and 8, the coin transfer device 30 further includes a transfer speed suppressing unit. The transport speed suppressing unit includes the bracket 36 and the seat 37.

The bracket 36 supports the seat 37. The bracket 36 is made of, for example, resin or metal. The bracket 36 has a shape in which a substantially plate-shaped member is bent or curved substantially vertically. The bracket 36 is bent or curved in a substantially L shape according to the inclination angle θ (see FIG. 9) of the seat 37. The bracket 36 is an example of an interposing member of the present invention.

The bracket 36 includes a first portion 36a and a second portion 36b. Each of the first portion 36a and the second portion 36b is a substantially plate-shaped member.

The first portion 36a is provided along the outer peripheral surface 322a of the peripheral wall portion 322 and is fixed to the outer peripheral surface 322a of the peripheral wall portion 322. The second portion 36b is connected to the first portion 36a and projects outward from the outer peripheral surface 322a of the peripheral wall portion 322 in the radial direction of the peripheral wall portion 322.

The sheet 37 suppresses the transport speed of the coin K. As the material of the sheet 37, for example, a material having elasticity or flexibility such as PET or rubber is used. Further, by using a material having a small friction coefficient such as a polyslider (registered trademark) sheet as the material of the sheet 37, when the coin K passes through the sheet 37, the lower end portion 37b of the sheet 37 (FIG. 12 (a)). Since the load applied to (see) can be reduced, the life of the sheet 37 can be extended.

The seat 37 is fixed to the second portion 36b of the bracket 36. The lower end 37b of the seat 37 projects downward from the second portion 36b of the bracket 36. The lower end portion 37b of the sheet 37 is arranged downstream (immediately downstream) of the discharge port 323.

When the sheet 37 is adhered and fixed to the second portion 36b, the entire entire surface of the sheet 37 facing the second portion 36b (the portion facing the second portion 36b) may be adhered to the second portion 36b. As a result, the sheet 37 can be stably fixed to the second portion 36b. Further, only the upper portion of the facing portion of the sheet 37 may be adhered to the second portion 36b, and the lower portion of the facing portion may not be adhered to the second portion 36b. As a result, the deformable region of the sheet 37 can be increased, and the transport speed of the coin K can be effectively suppressed.

When the rotating plate 321 rotates in the forward direction, the coin K located inside the peripheral wall portion 322 is discharged to the outside of the peripheral wall portion 322 via the discharge port 323 by centrifugal force. Forward rotation indicates that, in FIG. 7, the rotating plate 321 rotates in the forward rotation direction Y1 (clockwise). The inside of the peripheral wall portion 322 shows a space surrounded by the inner peripheral surface 322b of the peripheral wall portion 322.

The sheet 37 is arranged outside the peripheral wall portion 322. The sheet 37 is not provided along the outer peripheral surface 322a of the peripheral wall portion 322, but is inclined with respect to the outer peripheral surface 322a of the peripheral wall portion 322.

A transport surface 38 is arranged between the discharge port 323 and the transport rollers (convey roller 351 and transport roller 352).

The coin K discharged to the outside of the peripheral wall portion 322 through the discharge port 323 by centrifugal force slides on the transport surface 38 and is sent to the transport rollers (convey roller 351 and transport roller 352).

The lower end portion 37b of the sheet 37 is located on the movement path of the coin K discharged from the discharge port 323 by centrifugal force. That is, the lower end portion 37b of the sheet 37 is located between the discharge port 323 and the transfer roller (convey roller 351 and transfer roller 352).

The sheet 37 is arranged above the transport surface 38. There is a gap S between the lower end portion 37b of the sheet 37 and the transport surface 38. The vertical dimension of the gap S is smaller than the thickness of the coin K.

In FIG. 9, the rotation axis Z indicates the rotation axis of the rotation plate 321. The rotating plate 321 rotates about the rotation axis Z.

As shown in FIG. 9, the sheet 37 has a sheet surface 37a. The seat surface 37a is a surface of the seat 37 that is fixed to the second portion 36b of the bracket 36 and is opposite to the side.

The seat 37 is inclined with respect to the tangent line L of the peripheral wall portion 322 when viewed from the axial direction of the rotation axis Z. The axial direction of the rotating shaft Z is the extending direction of the rotating shaft Z. In this embodiment, the rotation axis Z extends in the depth direction of the drawing of FIG. The tangent line L is a virtual tangent line formed on the peripheral wall portion 322 when viewed from the axial direction of the rotation axis Z, and the portion of the discharge port 323 on the downstream side in the normal rotation direction Y1 (the coin K in the discharge port 323 is Pass through the discharged part).

In FIG. 9, the inclination angle θ indicates the inclination angle of the sheet 37 with respect to the tangent line L. The inclination angle θ is preferably 45 ° or more and 135 ° or less. The inclination angle θ is more preferably 90 °.

A procedure for the coin transporting device 30 to eject coins K through the ejection port 323 will be described with reference to FIGS. 10 to 14 (b).

FIG. 10 is a diagram showing a state in which the coin K is moving inside the peripheral wall portion 322. FIG. 11 is a diagram showing a state in which the coin K is discharged from the inside of the peripheral wall portion 322 to the outside of the peripheral wall portion 322 via the discharge port 323. FIG. 12A is a view of the sheet 37 shown in FIG. 11 as viewed from the direction of arrow R. The arrow R direction is a direction perpendicular to the tangent line L when viewed from the axial direction of the rotation axis Z (see FIG. 9). FIG. 12B is a plan view of the state shown in FIG. 12A. FIG. 13 is a diagram showing a state in which the coin K protruding from the discharge port 323 to the outside of the peripheral wall portion 322 is returned to the inside of the peripheral wall portion 322. FIG. 14A is a view of the sheet 37 shown in FIG. 13 as viewed from the direction of arrow R. FIG. 14B is a plan view of the state shown in FIG. 14A.

As shown in FIG. 10, when the rotating plate 321 rotates in the forward direction (rotates in the forward rotation direction Y1), the coin K located inside the peripheral wall portion 322 is positive while being along the inner peripheral surface 322b of the peripheral wall portion 322 due to centrifugal force. It moves in the rotation direction Y1. The forward rotation direction Y1 indicates the rotation direction of the rotating plate 321 when the coin K is discharged from the inside of the peripheral wall portion 322 to the outside of the peripheral wall portion 322 via the discharge port 323.

As shown in FIGS. 11, 12 (a), and 12 (b), when the coin K reaches the discharge port 323, it is discharged from the inside of the peripheral wall portion 322 by the centrifugal force generated by the rotation of the rotating plate 321. It is discharged to the outside of the peripheral wall portion 322 via the outlet 323.

When the coin K is ejected from the discharge port 323, the upper surface of the coin K touches the lower end portion 37b of the sheet 37. At this time, the lower end portion 37b of the sheet 37 bends in one side U1 (discharge direction) of the thickness direction U of the sheet 37. As a result, the sheet 37 gives the coin K an urging force in the direction opposite to the ejection direction (return direction) of the coin K, so that the momentum in the ejection direction of the coin K is suppressed. The discharge direction of the coin K is the moving direction of the coin K when the coin K is discharged from the discharge port 323 by the centrifugal force due to the rotation of the rotating plate 321. The thickness direction U is a direction perpendicular to the seat surface 37a. The one side U1 is in substantially the same direction as the discharge direction of the coin K from the discharge port 323.

A thin coin K such as a 1-yen coin has less bending of the sheet 37 when passing through the discharge port 323 than a thick coin K such as a 500-yen coin. Therefore, a thicker coin K is given a stronger urging force, whereas a thinner coin K is given a weaker urging force.

In general, the thicker the coin K, the stronger the momentum obtained by the centrifugal force, and the stronger the impact due to the collision with the transport rollers 351 and 352 and the impact due to the collision with another coin K being transported in front of the coin K. In addition, backflow of coin K is likely to occur due to these collisions. Therefore, by adjusting the length of the sheet 37 so that the sheet 37 gives the coin K an appropriate urging force according to the thickness of the coin K, the transfer roller 351 and the transfer roller 352 and the coin K can be brought into contact with each other. The impact generated by the collision can be mitigated. Further, the impact generated between the coins K due to the collision with another coin K being conveyed in front of the coin K can be alleviated. As a result, the coin K can be smoothly discharged. Further, it is possible to effectively prevent the backflow of the coin K due to the collision.

As shown in FIGS. 13, 14 (a), and 14 (b), when the coin K stays in the discharge port 323, the coin K cannot be smoothly sent to the transfer roller 351 and the transfer roller 352, so that the coin can be stored. There is a possibility that the coin K cannot be smoothly supplied to the corresponding room of the withdrawal device 1 (see FIG. 1). In this case, the rotating plate 321 is rotated in the reverse direction (rotated in the reverse rotation direction Y2). The reverse rotation direction Y2 is the direction opposite to the forward rotation direction Y1 (see FIG. 11).

When the rotating plate 321 rotates in the reverse direction, of the coins K protruding from the discharge port 323 to the outside of the peripheral wall portion 322, the portion remaining inside the peripheral wall portion 322 has a frictional force (in the reverse rotation direction Y2 from the rotating plate 321). Receives static friction force). Therefore, the coin K protruding from the discharge port 323 to the outside of the peripheral wall portion 322 can be rotated together with the rotating plate 321 in the reverse rotation direction Y2 and returned to the inside of the peripheral wall portion 322. As a result, the state in which the coin K is retained in the discharge port 323 can be eliminated.

Next, with reference to FIGS. 15 to 18 (b), a procedure in which the conventional coin transport device G discharges the coin K through the discharge port G3 will be described.

As shown in FIG. 15, the coin transport device G includes a peripheral wall portion G1 corresponding to the peripheral wall portion 322 of the present embodiment, a rotating plate G2 corresponding to the rotating plate 321 of the present embodiment, and an discharge port 323 of the present embodiment. It is provided with a discharge port G3 corresponding to. Further, the sheet H corresponds to the sheet H of the present embodiment.

FIG. 15 is a diagram showing a state in which the coin K is discharged from the inside of the peripheral wall portion G1 to the outside of the peripheral wall portion G1 via the discharge port G3. FIG. 16A is a view of the sheet H shown in FIG. 15 as viewed from the direction of arrow R1. The arrow R1 direction corresponds to the arrow R direction of the present embodiment. The tangent line L1 corresponds to the tangent line L of the present embodiment. FIG. 16B is a plan view of the state shown in FIG. 16A. FIG. 17 is a diagram showing a state in which the coin K protruding from the discharge port G3 to the outside of the peripheral wall portion G1 is returned to the inside of the peripheral wall portion G1. FIG. 18A is a view of the sheet H shown in FIG. 17 as viewed from the direction of arrow R1. FIG. 18B is a plan view of the state shown in FIG. 18A.

As shown in FIGS. 15, 16 (a) and 16 (b), the sheet H is fixed to the outer peripheral surface of the peripheral wall portion G1 so as to be inclined with respect to the outer peripheral surface of the peripheral wall portion G1. Instead, it is provided along the outer peripheral surface of the peripheral wall portion G1. The sheet H is not inclined with respect to the tangent line L1 when viewed from the axial direction of the rotation axis of the rotary plate G2, and is provided so as to substantially follow the tangent line L1.

When the coin K is ejected from the discharge port G3, the coin K does not face the seat surface H1 of the seat H, but faces the thickness portion H2 which is a portion constituting the thickness of the seat H.

The sheet H is fixed to the outer peripheral surface of the peripheral wall portion G1 and is provided along the outer peripheral surface of the peripheral wall portion G1. The sheet H is not inclined with respect to the tangent line L1 when viewed from the axial direction of the rotation axis of the rotary plate G2, and is provided so as to substantially follow the tangent line L1.

When the coin K is ejected from the discharge port G3, the upper surface of the coin K touches the lower end portion H3 of the sheet H. At this time, the coin K comes into contact with the thick portion H2 of the sheet H. As a result, the lower end portion H3 of the sheet H is bent in one side W1 (discharge direction) of the surface direction W of the sheet H. As a result, the sheet H gives the coin K an urging force in the direction opposite to the discharge direction (return direction) of the coin K, so that the momentum in the discharge direction of the coin K is suppressed. The surface direction W is a direction parallel to the sheet surface H1 and a direction perpendicular to the thickness direction of the sheet H. The one side W1 is in substantially the same direction as the discharge direction of the coin K from the discharge port G3.

As shown in FIGS. 17, 18 (a), and 18 (b), when the coin K stays in the discharge port G3, the rotating plate G2 is rotated in the reverse direction in order to eliminate the retention of the coin K.

With reference to FIGS. 14 (a) to 18 (b), the coin transport device 30 of the present embodiment is compared with the conventional coin transport device G.

As shown in FIGS. 14 (a), 14 (b) and 15, the rotating plate 321 rotates in the reverse direction, so that the coin K protruding from the discharge port 323 to the outside of the peripheral wall portion 322 moves into the peripheral wall portion 322. When returning, the lower end portion 37b of the sheet 37 comes into contact with the sheet surface 37a instead of the thick portion 37c of the sheet 37. As a result, the lower end portion 37b of the sheet 37 bends in the other side U2 (return direction) of the thickness direction U. As a result, since the sheet 37 gives the coin K an urging force F1 in the discharge direction, the momentum of the coin K in the backflow direction (the direction of returning to the inside of the peripheral wall portion 322) is suppressed.

As shown in FIGS. 17, 18 (a), and 18 (b), the coin K protruding from the discharge port G3 to the outside of the peripheral wall portion G1 is inside the peripheral wall portion G1 due to the reverse rotation of the rotating plate G2. When returning to, the lower end portion H3 of the sheet H comes into contact with the thick portion H2 of the sheet H instead of the sheet surface H1. As a result, the lower end portion H3 of the sheet H bends in the other side W2 (return direction) of the surface direction W. As a result, since the sheet H applies the urging force F2 to the coin K in the discharge direction, the momentum in the return direction (the direction in which the coin K returns to the inside of the peripheral wall portion G1) is suppressed.

Generally, the sheet 37 is more easily bent and has a smaller elastic modulus in the thickness direction U (see FIG. 14A) than in the surface direction W (see FIG. 16A). As a result, the urging force F1 which is the restoring force in the thickness direction U becomes smaller than the urging force F2 which is the restoring force in the plane direction W (F1 <F2). Therefore, the coin carrier 30 of the present embodiment has a urging force that hinders the process of returning the coin K when the process of returning the coin K to the inside of the peripheral wall portion 322 is performed, as compared with the conventional coin carrier G. Can be suppressed. As a result, the coin transport device 30 of the present embodiment can smoothly return the coin K to the inside of the peripheral wall portion 322 as compared with the conventional coin transport device G, so that the coin K stays in the discharge port 323. The condition can be effectively resolved.

As described above with reference to FIGS. 1 to 18 (b), the sheet 37 is inclined with respect to the outer peripheral surface 322 a of the peripheral wall portion 322 (see FIG. 8). As a result, as shown in FIGS. 13, 14 (a), and 14 (b), when the coin K is returned to the inside of the peripheral wall portion 322, the coin K is not on the thick portion 37c of the sheet 37 but on the seat surface 37a. Can be contacted. That is, the coin K can be brought into contact with the sheet surface 37a, which is the one that easily bends among the thick portion 37c and the sheet surface 37a. As a result, the increase in the urging force F1 can be suppressed, so that the coin K can be smoothly returned to the inside of the peripheral wall portion 322.
