Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stationary member and a rotating disk which rotates while being superposed on the bottom surface thereof. The present invention relates to a coin sorting device configured to sort according to a coin.

[0002]

2. Description of the Related Art Various types of coin sorting apparatuses have been proposed which are configured to sort coins sliding on the bottom surface of a fixed disk by rotation of a rotating disk according to the diameter.
In these coin sorting apparatuses, the coins held between the fixed disc and the fixed disc are conveyed in the rotating direction by an elastic member attached to the upper surface of the rotating disc. In addition, coins conveyed in the rotating direction by the rotating disk are selectively guided according to the diameter while sliding on the bottom surface of the fixed disk, and are respectively discharged to the outside of the fixed disk. Therefore, the sorted coins slide in the radial direction while being conveyed in the rotating direction.

[0003]

The above-mentioned conventional coin sorting apparatus has the following problems. First, since the surface side of the elastic member is made of synthetic rubber having relatively low abrasion resistance, such as butyl rubber, for example, a decrease in coin transport force due to abrasion occurs at a relatively early stage. It is difficult to secure the coin sorting operation for a long period of time.

Further, since the surface of the elastic member is a substantially smooth surface, and there is no difference in coin holding force depending on the direction, if an attempt is made to increase the conveying force of the coin in the rotating direction, it is necessary to restrict the coin in the radial direction. There is a trade-off relationship in which the force becomes too large. Therefore, there is a problem in increasing the certainty of the coin sorting operation.

The present invention has been made in consideration of the above-described problems, and an object of the present invention is to provide a coin sorting apparatus capable of ensuring a more reliable coin sorting operation for a long period of time. Aim.

[0021]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 to 15 are views showing one embodiment of a coin sorting apparatus according to the present invention.

[Outline of Overall Structure] As shown in FIGS. 1 and 2, the coin sorting apparatus according to the present embodiment rotates with a fixed disc (fixed member) 1 superposed on the bottom surface of the fixed disc 1. And a rotating disk 2. The fixed disk 1 and the rotating disk 2 are connected to each other by a hinge part a1 (FIG. 1) so as to be freely opened and closed. Also, the hinge part a1
On the opposite side, a lock portion a2 (FIG. 1) for fixing the fixed disk 1 and the rotating disk 2 to each other so as to overlap and fix in a closed state is provided.

The fixed disk 1 has a coin slot 1a at the center. And this coin sorting device has a fixed disk 1
The coin inserted from the coin insertion slot 1a is configured to slide with respect to the bottom surface 1b (FIG. 2) of the fixed disk 1 as the rotating disk 2 rotates. In addition, the fixed disk 1
It has guide means (described later) for selectively guiding coins sliding on the bottom surface 1b according to the diameter.

[Specific Structure of Rotating Disk] The rotating disk 2
As shown in FIGS. 2 and 3, the disk body 22 includes a disk body 22 rotatably supported by a shaft 20, and a disk-shaped elastic member 200 attached to the upper surface of the disk body 22. The elastic member 200 has a thin urethane rubber layer 201 on the upper surface side and a porous elastic material layer 206 provided below the urethane rubber layer 201, as shown in FIGS. The porous elastic material layer 206 has a relatively high resilience (for example, a 25% compressive load of 630 to 950 g / cm).
It is preferably made of about ² ) sponge rubber (foam rubber).

As shown in FIGS. 3 to 5, a plurality of radial grooves 202 are formed on the surface 203 of the urethane rubber layer 201. These radial grooves 202 are formed at intervals I between the grooves 202 on the outer peripheral portion of the elastic member 200 (see FIG. 5).
(B)) is arranged to be smaller than the diameter of the coin having the smallest diameter.

As shown in FIG. 5, a mark 204 having a smaller depth than other portions is provided in a part of the radial groove 202 in the urethane rubber layer 201. For example, the thickness of the urethane rubber layer 201 is about 1 mm, and the depth of the radial groove 202 is D2 in the mark portion 204.
= 0.1 mm, and D1 = 0.3 mm in other portions.

The urethane rubber layer 201 having such a radial groove 202 can be easily manufactured by injection molding by using thermoplastic urethane rubber as a material.

Next, as shown in FIGS. 2 to 4, a disk-shaped metal plate 23 is fixed to the bottom surface of the elastic member 200. The elastic member 200 is detachably attached to the disk main body 22 via the metal plate 23 by four screws 29 (FIGS. 2 and 3). In addition,
The rotary disk 2 has a center hole 200a (FIG. 3) for receiving the head of the screw 29. This center hole 200
a is closed by a conical member 27 for preventing the inserted coins from stagnating in the central portion of the rotating disk 2. Further, screw holes 22 a corresponding to the four screws 29 are formed in the center of the disk main body 22.

The elastic member 200 attached to the disk main body 22 holds coins between the fixed disk 1 and the coin, moves the coin with the rotation of the rotating disk 2, and moves the fixed disk 1.
It is possible to absorb a change in the gap between the coins and the difference in the thickness of the coin due to the denomination (see FIGS. 6, 9 to 11).

As shown in FIG. 1, a motor 25 for rotating the rotating disk 2 is provided. Specifically, a pulley 26 attached to the rotation shaft of the motor 25
And between the outer periphery of the disk body 22 of the rotating disk 2 (FIG. 2)
A drive belt 28 is stretched.

[Specific Structure of Fixed Disk] Next, the fixed disk 1, and particularly the above-mentioned guide means provided on the bottom surface 1b thereof will be described in detail with reference to FIGS.

The guide means has a coin passage 10 formed in a concave shape on the bottom surface 1b of the fixed disk 1. The coin passage 10 extends in a substantially spiral shape while meandering from the coin insertion slot 1a side to the outer peripheral side (counterclockwise in FIG. 7).
The coin passage 10 is divided into a large-diameter coin passage 10a, a medium-diameter coin passage 10b, and a small-diameter coin passage 10c in order from the coin insertion slot 1a. As shown in FIGS. 7 and 8, the large-diameter coin passage 10a has a passage width through which the large-diameter coin C1 can pass, and the middle-diameter coin passage 10b has a passage through which only the middle-diameter coin C2 and the small-diameter coin C3 can pass. The small-diameter coin passage 10c has a width L2 (FIG. 7) through which only the small-diameter coin C3 can pass.

As shown in FIG. 7, the large-diameter coin passage 10a
Is a coin introduction part 11 facing the coin insertion slot 1a, and two stepped parts 12a, 1 formed at an interval downstream thereof.
2b. Among these, the coin introduction part 11 is formed so that the gap between the rotating member 2 and the elastic member 200 is wider than the thickness of the thickest coin. Thus, all coins entered from the coin insertion slot 1a can enter the coin introduction unit 11 by centrifugal force generated by the rotation of the rotating disk 2.

The step portions 12a and 12b intermittently narrow the gap between the large-diameter coin passage 10a and the elastic member 200 of the rotating disk 2 toward the downstream side, thereby eliminating the overlap between coins. Thus, it is intended to ensure the transfer of coins in a single line in the coin passage 10.
Such a state of the coin C is shown in FIG. 9 (cross-sectional view taken along the line XX in FIG. 8 (when the coin passes)).

Incidentally, as shown in FIG.
An overlapping coin return portion 13 facing the coin insertion slot 1a is provided corresponding to a boundary portion between 0a and the medium-diameter coin passage 10b. The overlapping coin return section 13 includes a step 12a,
This is for dealing with coins that have passed while overlapping with 12b, and the upstream side and the downstream side thereof are surrounded by a step 13a and a step 13b, respectively.

The step 13a on the upstream side is formed to be thinner than the thinnest coin (see FIG. 10), and only one of two overlapping coins (coin on the rotating disk 2 side) is inserted into the coin slot 1a. It is made to pass to the side. The downstream step 13b guides coins passing through the upstream step 13a and returns the coins to the coin insertion slot 1a.

Here, the large-diameter coin passage 10a moves toward the outer periphery as it goes downstream (away from the center of the fixed disk 1), so that the outer edges of all coins passing therethrough become the inner peripheral portion 10i-a. The contact is made (see FIG. 8).

Next, as shown in FIGS. 7 and 8, on the outer peripheral side of the medium-diameter coin passage 10b, a large-diameter coin for selectively guiding only the large-diameter coin C1 and discharging it in a substantially tangential direction. A guide part 15a is provided. This large-diameter coin guide 15a
Has a climbing portion 16a and a discharge passage 17a.
The rising portion 16a is located at the boundary between the large-diameter coin passage 10a and the medium-diameter coin passage 10b, and only the large-diameter coin C1 having a diameter larger than the passage width L1 of the medium-diameter coin passage 10b. Are mounted on the outer peripheral side (see FIG. 8 and FIG. 11 (cross-sectional view taken along the line YY in FIG. 8)). Note that a slope 16a '(FIG. 7) for assisting the coins to climb up is provided downstream of the climbing section 16a.

The discharge passage 17a is provided in the
Edge 18 for guiding coins riding on the vehicle in a substantially tangential direction
a, and a discharge port 19a for discharging the guided coin to the outside of the fixed disk 1. In this case, since the outer edges of all the coins are configured to abut on the inner peripheral edge portion 10ia, a medium-diameter coin C2 having a diameter smaller than the passage width L1.
The small-diameter coin C3 passes through the medium-diameter coin passage 10b without climbing on the climbing section 16a.

Next, on the outer peripheral side of the upstream portion of the small-diameter coin passage 10b, there is provided a medium-diameter coin guide portion 15b for selectively guiding only the medium-diameter coin C2 and discharging it in a substantially tangential direction. . The medium-diameter coin guide portion 15b also has a climbing portion 16b and a discharge passage
b.

The climbing portion 16b is located at a boundary between the medium-diameter coin passage 10b and the small-diameter coin passage 10c.
Only the medium-diameter coin C2 having a diameter larger than the passage width L2 of the small-diameter coin passage 10c runs on the outer peripheral side thereof. A slope 16b '(FIG. 7) for assisting the coins to climb up is also provided on the downstream side of the climbing section 16b. Further, the discharge passage 17b is provided with the large-diameter coin guide portion 15
a, as in the discharge passage 17a of FIG.
9b.

Here, the downstream portion of the medium-diameter coin passage 10b also moves toward the outer periphery toward the downstream (away from the center of the fixed disk 1), so that the outer edges of all coins passing therethrough become the inner peripheral portion. 10i-b (see FIG. 8). As a result, the small-diameter coin C3 having a diameter smaller than the passage width L2 passes through the small-diameter coin passage 10c without riding on the climbing portion 16b.

The small-diameter coin passage 10c is directed toward the outer periphery as it goes downstream (once toward the inner periphery side), and selectively guides only the small-diameter coin C3 and discharges it in a substantially tangential direction. As the guide portion 15c (the discharge port 19 thereof)
c).

The coin passage 10 has an inner peripheral edge 10i and an outer peripheral edge 10o with which an outer edge of a coin passing therethrough can contact.
And, as described above, each of the riding portions 6a, 6
On the upstream side of b, as it goes downstream, it moves away from the center of the fixed disk 1 so that the outer edges of all coins become inner peripheral portions 10i-
a, 10i-b. And
The coin passage 10 is located downstream of each of the climbing sections 6a and 6b.
As it goes downstream, it curves so as to approach the center of the fixed disk 1 and has a meandering shape as a whole.

Next, as shown in FIGS. 7 and 8, the fixed disk 1 is provided with foreign matter sorting means 8 provided downstream of the coin passage 10. The coin sorting means 8 is for selectively guiding foreign matter F thinner than the thinnest coin and discharging it to the outside of the fixed disk 1 (see FIG. 8). Examples of such foreign matter F include a wire-made document clip and a stapler (document binding device) needle. As shown in FIGS. 7, 8, and 12 to 15, the foreign matter sorting means 8 has a foreign matter passage 80 branched from the small-diameter coin passage 10c and leading to the outside of the fixed disk 1. A step 82 is provided.

The foreign material passage 80 extends in a direction (tangential direction) substantially perpendicular to the radial direction of the fixed disk 1 at the branch portion thereof, and the small-diameter coin passage 10c is larger than the fixed disk 1
(See FIGS. 7 and 8). In addition, the step portion 82 of the branch portion has a gap (height) between the elastic member 200 of the rotating disk 2 and the size (height) of the thinnest coin (in this case, the small-diameter coin C3) that does not allow the foreign matter F to pass through. Has formed.

As shown in FIGS. 14 and 15, with respect to the foreign matter F having a rounded edge such as a wire-made document clip, even if the foreign matter F is slightly thicker than the gap 84, the elastic member 200 is deformed. In some cases, it can pass through the stepped portion 82. Therefore, the size of the gap 84 is set in consideration of such a case. For example, the size of the gap 84 is set to about 0.8 mm for the thinnest coin C3 having a thickness of 1.2 mm.

[Operation and Effect] Next, the operation and effect of the coin sorting apparatus having the above-described configuration will be described. The operation or action that is clear from the above configuration will be partially omitted or simplified.

First, when performing a normal coin sorting process, the rotating disk 2 rotates clockwise in FIG. And
The coin inserted into the coin insertion slot 1a of the fixed disk 1 enters the coin introduction portion 11 with the rotation of the rotating disk 2, and slides in the coin passage 10 while sliding with respect to the bottom surface 1b of the fixed disk 1. It will be transferred.

Then, of the coins that have reached the climbing portion 16a of the large-diameter coin guide portion 15a through the large-diameter coin passage 10a, only the large-diameter coin C1 that has climbed on the climbing portion 16a passes through the discharge passage 17a. The light is discharged from the discharge port 19a. Other medium and small coins C2 and C3 pass through the medium coin passage 10b as they are.

Next, among the small and medium-sized coins C2 and C3, which have reached the rising portion 16b of the medium-diameter coin guide portion 15b through the medium-diameter coin passage 10b, the medium-sized coin C2 which has climbed onto the rising portion 16b. Only discharge port 1 through discharge passage 17b.
Emitted from 9b. The other small-diameter coin C3 passes through the small-diameter coin passage 10c as it is and is discharged from the discharge port 19c of the small-diameter coin guide 15c.

Also, as shown in FIG.
Since the coin C3 among the small-diameter coin C3 and the foreign matter F passing through 0c cannot pass through the step portion 82 of the branch portion, the coin passage 1
Forcibly guided to the discharge port 19c along 0c. On the other hand, the foreign matter F thinner than the coin C3 advances in the tangential direction by the rotational force and the centrifugal force by the rotating disk 2, and the step 8
2 and enters the foreign object passage 80 and is sorted out from the coin C3. Then, by discharging the selected foreign matter F from the foreign matter passage 80 to the outside of the fixing member 1, such foreign matter F can be collected separately from the coins C1 to C3.

As described above, each coin guide portion 15a-
At 15c, coins are sorted according to the diameter, and the foreign matter F is also sorted by the foreign matter sorting means 8.

Here, the elastic member 200 of the rotating disk 2 in the present embodiment has the urethane rubber layer 201 on the upper surface side, so that the abrasion resistance is improved as compared with the case where another synthetic rubber material or the like is used. Can be. Further, since the plurality of radial grooves 202 formed on the surface 203 of the urethane rubber layer 201 engage with the outer peripheral edge of the coin C (see FIG. 6), the binding force of the coin C in the radial direction of the rotating disk 2 is reduced. It is possible to increase only the conveying force of the coin C in the rotation direction without increasing.

Further, a plurality of radial grooves 2 are formed on the surface 203.
Since the urethane rubber layer 201 is easily deformed by the formation of 02 (see FIG. 6), even when coins having different thicknesses are arranged, they can be reliably held. As described above, according to the present embodiment, a more reliable coin sorting operation can be ensured over a long period of time.

Further, since the distance between the radial grooves 202 on the outer peripheral portion of the elastic member 200 is made smaller than the diameter of the coin having the smallest diameter, even if coins having a small diameter continue in the circumferential direction, all the coins can be connected. By ensuring that coins are always located on the radial groove 202, the above-described effects of the radial groove 202 can be always maintained. In addition, since a part of the radial groove 202 in the urethane rubber layer 201 is provided with the mark part 204 which is shallower than other parts,
When the urethane rubber layer 201 is worn, first the mark 2
Eliminating the groove of FIG. 4 (FIG. 5) can be used as a guide to know the degree of wear and the time of replacement.

Next, the elastic member 200 is made of the urethane rubber layer 2.
By providing the porous elastic material layer 206 underneath 01, the amount of the entire elastic member 200 that can be compressed and deformed can be increased, so that it is possible to flexibly cope with coins of various thicknesses. In addition, by using sponge rubber having particularly high resilience among porous elastic materials as a material of the porous elastic material layer 206, even when coins having different thicknesses are lined up, coins formed by the elastic member 200 can be used. Can be more reliably held.

Further, the elastic member 2 with respect to the disk body 22
Since the mounting of the elastic member 200 can be performed detachably by the screw 29 via the metal plate 23 (see FIG. 3), the replacement of the elastic member 200 can be performed very easily.

[0059]

According to the present invention, since the elastic member of the rotating disk has the urethane rubber layer on the upper surface side, the wear resistance can be improved as compared with the case where another synthetic rubber material or the like is used. . Also, by engaging a plurality of radial grooves formed on the surface of the urethane rubber layer with the outer peripheral edge of the coin,
It is possible to increase only the transport force of coins in the rotating direction without increasing the binding force of the coins in the radial direction of the rotating disk. Furthermore, since a plurality of radial grooves are formed on the surface, the urethane rubber layer is easily deformed, so that even when coins having different thicknesses are arranged, they can be reliably held. By the above,
ADVANTAGE OF THE INVENTION According to this invention, a more reliable coin sorting operation can be ensured over a long period of time.
