Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coin dispensing device, and more particularly to a coin dispensing device of the type that dispenses coins by utilizing the centrifugal force of a rotating disk.

[Prior art and its problems]

Conventionally, a coin dispensing device using the above-mentioned rotating disk includes a rotating disk, a coin passage extending around the periphery of the rotating disk, and a coin passage provided above the rotating disk from the periphery to the entrance of the coin passage. A thickness regulating member is provided to regulate the thickness direction of the coins. The thickness regulating member is installed at a position slightly higher than the thickness of the coins to be processed, so that only one coin can enter under the thickness regulating member and reach the coin passage, and two coins are piled up and placed in the coin passage. Its role is to prevent entry. The coin passage is used as a coin counting passage or a sorting passage for sorting coins by type depending on the purpose of use, and is used as a coin counting machine or a coin sorting machine.

However, the thickness of the coins to be processed differs depending on the denomination, and in extreme cases, thicker denomination coins are more than twice as thick as thinner denomination coins, so the thickness is extremely large. It is impossible to count or sort different coins in a mixed state with the above-mentioned coin dispensing device. This is because the thickness regulating member facing the rotating disk must be set at a sufficient height to allow thick coins to pass through, so thin coins may enter in two layers, or the thickness regulating member may pass through. This is because it gets stuck between it and the top surface of the rotating disk. Therefore, the conventional coin dispensing device of this type can only be used for counting or sorting coins of similar denominations in thickness, and has the disadvantage that its range of use is severely limited. Furthermore, even when counting single denomination coins, if deformed coins or other thick coins were mixed in, these coins would jam under the thickness regulating member, causing processing problems. .

As described above, the conventional coin dispensing device using a rotating disk has a fatal defect in that it cannot avoid the trouble of coin jamming because it is equipped with a thickness regulating member.

In order to solve these problems, the inventors of the present invention have devised a device disclosed in Japanese Patent Application Laid-Open No. 58-94081. This device eliminates the need for the conventional thickness regulating member, and forms the surface of the rotating disk so that the second surface portion on the outer side in the radial direction is raised one step higher than the first surface portion extending over a predetermined radial area from the center of rotation. The height of the coin is lower than the thickness of the coin to be processed, and the boundary wall formed between the first surface part and the second surface part which is one step higher than the first surface part is used as the thickness regulating part. It is. That is, due to this boundary wall, only the first layer of coins remains on the first surface, and the second and higher layers of coins are transferred onto the second surface, thereby forming a single layer.

The coins that were further regulated by the boundary wall were the first
The coins are fed into the coin passageway facing the surface and transported out. In addition, the coins transferred to the second surface side are again placed on the first surface side.
returned to the surface.

In this way, according to the above device, it is possible to form a single layer without using a thickness regulating member, and it is possible to solve the problems caused by using a thickness regulating member, but there are other problems as described below. It was found that this occurs as follows.

That is, in the above device, since the boundary wall between the first surface portion and the second surface portion of the rotating disk is used as the thickness regulating portion, the coin passage can jump from the first surface portion to the boundary wall and the second surface portion. direction, i.e. the first
It is formed diagonally upward from the surface. Further, above the starting end of this coin path, rollers for holding and transporting coins, a pulley for a transport belt, etc. are provided.

Therefore, when the coins layered on the boundary wall move from the first surface to the bottom of the coin passage, the coin surface changes diagonally upward in an unstable state, and when the coin changes its posture, the rollers and the transfer If there is even a slight delay in the timing when the pulley or the like of the belt holds the coin, the coin and the next coin may be caught together, causing a coin jam in that area. Another problem is that the higher the speed at which the rotary disk and the rollers move the conveyor, such as a pulley, the more frequently coins jam, making it impossible to improve coin processing efficiency.

[Purpose of the invention]

The present invention has been made with the aim of improving the above-mentioned problems of the prior art, and allows coins to be made into a single layer without providing a thickness regulating member, and does not cause coin jams. A coin dispensing device is provided.

[Summary of the invention]

In order to achieve the above object, the coin dispensing device according to the present invention includes a rotating disk that moves supplied coins to the periphery by centrifugal force, and a mechanism that is located along the periphery of the rotating disk and is kept in a fixed state at least during operation. A thickness regulating wall supported on the stand side and having a height lower than the thickness of the coins to be processed from the surface of the disk to allow the second layer of coins to overflow, and a thickness regulating wall portion that allows the first layer of coins to be placed outside the periphery of the rotating disk. a fixed wall having a notch for ejecting coins in the direction; and a passage bottom surface provided facing the notch of the fixed wall and substantially flush with the surface of the rotating disk, and receiving coins released from the notch. It is characterized by comprising a coin passage for conveying coins, and a coin recirculation means for receiving coins that have passed through the thickness regulating wall portion of the fixed wall and sending them back onto the rotating disk.

[Embodiments of the invention]

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 shows the external appearance of an embodiment of the present invention, FIG. 2 shows the main parts, FIG. 3 shows the same plane, and FIG. 4 shows the same longitudinal section. The center portion of the disc 1 has a gentle conical shape, and the center portion of the disk 1 is fixed to a central shaft 3 that is rotatably supported on the machine stand 2 side.

Referring to FIG. 4, an annular fixed wall 4 supported by a machine base 2 is disposed around the periphery of the rotary disk 1. As shown in FIG. The fixed wall 4 in this embodiment is formed by standing up on the circumference of a disc-shaped dish-shaped part, and this dish-shaped part 4A
A lower part of a boss portion 4B protruding from the lower surface of the center thereof is fixed to the machine base 2, and the central shaft 3 is rotatably supported at the center of the boss portion 4B via bearings 5, 5.

As shown in FIG.
A thickness regulating wall portion 6 in which the three-circumferential region
The regions Y and Z from the entrance of the coin passage 7 arranged in the tangential direction of the rotating disk 1 to the downstream side in the rotational direction of the first disk 1 are the notches 8 and 9.
It is said that

In particular, the fixed wall portion of the notch 8 in region Y where the notch 8A is formed is formed lower than the upper surface of the rotating disk 1 by the thickness of the passage bottom plate 7A forming the passage bottom of the coin passage 7. When the starting end portion of the passage bottom plate 7A is positioned on the upper surface, the upper surface of the passage bottom plate 7A becomes substantially flush with the upper surface of the rotary disk 1. In addition, the fixed wall portion where the notch portion 8B is formed is flush with or slightly lower than the upper surface of the rotary disk 1 and the upper surface of the passage bottom plate 7A, so that coins that have not been fed into the entrance of the coin passage 1 are directed outward. It is designed to be released. The portion of the fixed wall 4 in which the notch 9 is formed in the remaining region Z is an inclined surface that slopes upward from the outside to the inside, as shown in FIG.

The role of this inclined surface is to guide the guide 20, which will be described later.
I will mention this when explaining.

A discharge notch 7C is formed between the terminal end 6B of the thickness regulating wall 6, which is the starting end of the notch portion 8A, and the starting end of the passage side plate 7B on the coin feeding direction side by the rotating disk 1 of the coin passage 7. When coins trying to enter the entrance of the coin passage 7 are stopped at the entrance, some of the coins are ejected outward from the ejection notch 7C in front of the entrance of the coin passage 7, Coin jams caused by coins stagnation at the entrance are prevented.

An outer disk 10 is provided on the outer circumference of the fixed wall 4 and constitutes a coin circulation means for circulating the coins C onto the rotating disk 1. This outer wheel disc 10
is placed in an inclined position so that the starting end 6A side of the regulating wall portion 6 of the fixed wall 4 is high and the ending end 6B side thereof is low, and the low part of the outer ring disc 10 (the part on the ending end 6B side) is located below the coin passage 7. Furthermore, a support member 1 is supported on the outer periphery of the boss portion 4B of the fixed wall 4 via bearings 11, 11.
The supporting member 12 and the outer ring plate 10 are combined. In this example, the high part of the outer ring disc 10 (the part on the side of the starting end 6A) is located at a slightly higher position than the terminal end 9B forming part of the notch 9 of the fixed wall 4 and the upper surface of the rotating disc 1. The lower position may be used as long as it does not interfere with the feeding of coins from the disk 10 to the rotating disk 1.

The outer circumferential edge of the outer ring plate 10 is supported by a plurality of support plates 15, 15... provided upright on the machine stand 2 side, and guide rollers 16, 16... (in this embodiment) are arranged annularly on the outer circumferential edge. In the example, it is installed at four locations every 90 degrees) and can be rotated. Therefore, after adjusting the degree of inclination of the outer race disk 10 with respect to the support member 12, the degree of inclination of the outer race disk 10 is determined by pinching and holding the peripheral edge of the outer race disk 10 with each guide roller 16, 16, .

Further, referring to FIGS. 2 and 3, a peripheral wall 1 with a constant radius is supported around the outer race disk 10 by support plates 15 and 15' (see FIGS. 1 and 4).
7 is provided, and following this peripheral wall 17, the notch 9
A guiding wall 18 is formed extending in an arc from near the starting end 9A of the area Z toward the ending end 9B to near the center in the radial direction on the outer ring disc 10. A guide member 19 is connected to the guide member 19 having a height that allows the guide member to climb over the layers. The other end of the guide member 19 is fixed near the end 9B of the notch 9 forming portion of the fixed wall 4, and the guide wall 18 and the guide member 19 constitute a guide guide 20.

Note that the guiding guide 20 may be configured only of the high guiding wall 18 so that the coins on the outer wheel disk 10 are always fed into the rotating disk 1. However, if the amount fed is large, the coins may not be reliably stacked until they reach the entrance of the coin passage 7. Therefore, in this example, the guide member 19 feeds the thinnest coins C up to the second layer into the rotating disk 1, and the coins from the third layer and above are returned onto the outer disk 10, thereby reducing the amount of coins fed into the rotating disk 1. I'm trying to be controlled.

The guidance guide 20 extends inward in the radial direction on the outer race disk 10 in an arc shape from near the starting end 9A of the notch 9 toward the ending end 9B, so that the guiding wall 1
The distance between the guiding member 8 and the notch 9 forming portion of the fixed wall 4 becomes narrower in the direction of rotation of the outer race disk 9. As a result, the outer circumferential side coins on the outer ring disc 9 and the coins on the inner side are moved to the guide wall 18.
Alternatively, it is assumed that clogging occurs between the guide member 19 and the portion of the fixed wall 4 where the notch 9 is formed. Therefore, by forming the portion of the fixed wall 4 where the notch 9 is formed into an inclined surface, coin jamming can be eliminated and coins can be smoothly fed into the rotating disk 1.

As shown in FIG. 4, the transmission system of the driving force to the rotating disc 1 and the outer disc 10 is a helical gear of a transmission shaft 22 which is supported on the machine base 2 and whose rotation is transmitted from a motor (not shown) through a pulley 21. 23 is the central axis 3
It meshes with the upper gear 24 to impart rotation to the center shaft 3, and from another gear 25 on the center shaft 3 toward the gear 26 fixed to the outer periphery of the boss portion of the support member 12. Rotation is applied through intermediate gears 27 and 28 that are pivotally supported on the machine base 2. Note that 29 is a pulley for imparting rotation to a sorting disk 30 (shown in the first diagram) that sorts the coins C sent out from the coin passage 7 by denomination.

Through the above mechanism, the circumferential speed of the outer circumferential edge of the rotating disk 1 is rotated at a circumferential speed that is equal to or faster than the circumferential speed of the inner circumferential edge of the outer disk 10 (near the fixed wall 4), and the coins on the outer disk 10 are is arranged so that it smoothly slides onto the rotating disk 1.

As schematically shown in FIG. 1, the coin passage 7 includes a passage bottom plate 7A provided on the same surface as the upper surface of the rotary disk 1, and an entrance portion of the passage bottom plate 7A (between the passage bottom plate 7A and the rotary disk 1). Coin gripping roller 31 provided on the boundary portion of each upper surface) and a transfer belt 3 disposed on the downstream side of this gripping roller 31
2, and discriminators 33, 33 are installed at appropriate locations on the coin passage 7 to determine the authenticity and denomination of the coin.
(a magnetic sensor in the embodiment) is provided.

The shaft 34 of the gripping roller 31 is connected to the machine base 2.
A bracket 36B is fixed to the side of the support structure 36A, which can be opened around a support shaft (not shown).
The pulley 35 of the transfer belt 32
A, 35A... and each presser roller 35B, 35B between each pulley 35A, 35A is attached to the side of the passage 7 side of the support structure 36A provided on the machine base 2 side by a plurality of fixing bars 36C, 36C... The pulleys 35A, 35A... of the transfer belt 32 and the respective presser rollers 35B, 35B... are pivotally supported between the two frame bodies 36D, 36D, which are fixed together. spring 37 to be inserted;
37... biased downward (toward the passage bottom plate 7A side), and can be moved up and down separately. The lower end of the peripheral surface of the gripping roller 31, each pulley 35A, 35A..., each presser roller 35B, 35B
...However, the lower surface of the transfer belt 32, whose height position is determined, is located at a height smaller than the thickness of the thinnest coin with respect to the upper surface of the rotary disk 1 and the upper surface of the passage bottom plate 7A, and the height position is determined according to the thickness of the coin. It is designed to rise to the thickness height.

The rotational speed of the gripping roller 31 is automatically changed according to the thickness of the coin C held in its grip, in order to maintain an appropriate feeding interval between coins when transferring them to the transfer belt 32 regardless of the difference in diameter of the coin C. The automatic transmission mechanism 38 is equipped with an automatic transmission mechanism 38. That is, when the coin C is thick, it is regarded as a large-diameter coin and the number of revolutions is increased, and when the coin C is thin, the number of revolutions is reduced and sent out.

A specific example thereof is as shown in FIG.
is supported by a horizontal shaft 40 in a direction perpendicular to the shaft 34, and supports the gripping roller 31 so as to be movable in the direction of arrow P, and a variable speed roller 41 bulging in an arc shape is fixed to the other end of this shaft 34. There is. Further, another shaft 42 is provided on the shaft support piece 36E to which the support structure 36A is fixed, and a piece 43 inserted therein is swingably supported by a horizontal shaft 44 in a direction perpendicular to the shaft 42. The shaft 42 has the speed change roller 4
The speed change roller 41 is moved so that a part of the speed change roller 41 is in contact with the circumferential surface of
Tapered roller 4 having a taper in the opposite direction to
A pulley 46 to which rotation is transmitted is fixed to the other end of the shaft 42.

An elastic ring 47 made of a spring, rubber, or the like is wound around one end of the speed change roller 41 and the tapered roller 45 so that the two rollers 41 and 45 are always in contact with each other. Due to the elastic force of the elastic ring 47 and the keeping of the rollers 41 and 45 in contact, a counterclockwise rotational force is applied to the grip roller 31 around the shaft 40, but it is not fixed to the piece 39. Due to the contact with the stoppers 39a and 39b, the gripping roller 31 is positioned at a height lower than the thickness of the thinnest coin.

Therefore, if the coin C that enters under the gripping roller 31 is thick, the gripping roller 31 will be pushed up significantly, so the contact point between the speed change roller 41 and the taper roller 45 will shift to the left in the figure, and the taper roller The large diameter side of 45 is the speed change roller 4
1 and the rotation is transmitted to the gripping roller 31 at increased speed. In the case of thin coins,
On the contrary, the amount of push up of the gripping roller 31 is small;
The small diameter side of the tapered roller 45 and the large diameter side of the speed change roller 41 come into contact, and rotation is transmitted to the gripping roller 31 at a reduced speed.

Since the sorting disk 30 is not directly related to the present invention, detailed description thereof will be omitted. In FIG. 1, 48 is a level detection switch for keeping the amount of coins on the outer ring disc 10 at an appropriate level, 49 is its operating rod, and 5
0 is a coin supply disk whose rotation is controlled by the switch 48.

In the above embodiment, the circumferential speed near the outer peripheral edge of the rotating disk 1 is v ₁ , and the circumferential speed of the gripping roller 31 is V ₂ x (the value of v ₂ x changes depending on the thickness of the coin). If the peripheral speed of the transfer belt 32 is v ₃ , then v ₃
The velocity relationship is ＞v ₁ ＞v ₂ x. As a result, the coin about to be sent out from the rotary disk 1 is gated by the gripping roller 31 and transferred to the transfer belt at the circumferential speed v2x of the gripping roller 31.
Sent to the 2nd side. Due to the gate action of the gripping roller 31, when subsequent coins are stagnant at the entrance of the coin passage 7, some of the coins are ejected from the ejection notch 7C and the notch portion 8B, and the coins at the entrance are ejected. stagnation will be resolved.

The distance between the gripping roller 31 and the pulley 35A at the starting end of the transfer belt 32 is approximately 20 mm in this embodiment, and for coins with a diameter of 20 mm or more, the leading edge of the coin is at the position of the pulley 35A at the starting end. While the coin is gripped under the transfer belt 32, the trailing edge of the coin is gripped by the gripping roller 31. In this state, the coin is transported at the peripheral speed v ₂ x of the gripping roller 31, and only after the trailing edge of the coin comes off the gripping roller 31 is the coin transported at the peripheral speed v ₃ of the transfer verna 32. In other words, while the coin is being held by the gripping roller 31, even if a part of it is in contact with the rotating disk 1 or the transfer belt 32, the coin is fed by the diameter of the coin at the circumferential speed v ₂ x of the gripping roller 31. Since the circumferential speed v ₂ x of this gripping roller 31 is changed according to the coin thickness, which is proportional to the coin diameter, the distance between the centers of the coins fed between the transfer belts 32 is independent of the coin diameter. A certain size or more is guaranteed. This center distance dimension is
A sorting disk 3 that rotates continuously at the same speed as the transfer belt 32
Coin receiving recesses 30a, 30 formed at 0
The pitch size of the coin receiving recesses 30a is the same or larger, and prevents two coins from entering one of the coin receiving recesses 30a at the same time. However, it is not always necessary to insert coins one by one into the recesses 30a, 30a, .

Next, the operation of the above embodiment will be explained.

The coins C supplied onto the outer wheel disk 10 through the supply disk 50 are sent by the rotation of the outer wheel disk 10 in the direction of the arrow, and are brought toward the rotating disk 1 side along the guide wall 18. At this time, coins within the second layer of the thinnest coins are sent onto the rotating disk 1 from the inclined surface 9 of the fixed wall 4 along the guiding member 19. Further, the thinnest coins in the third layer and above are returned to the outer wheel disk 10 by passing over the guiding member 19.

The coin C that has entered the rotating disk 1 moves along the inner circumference of the fixed wall 4 due to centrifugal force, and the coins in the second and higher layers are sent out onto the outer disk 10 again in the area XX of the regulating wall 6. Only the first layer coins enter the coin passage 7 through the cutout portion 8A corresponding to the entrance of the coin passage 7.

When several coins are stuck at the entrance of this coin passage 7, some of those coins are removed from the ejection notch 7C.
Coins that are ejected into the outer wheel disk 10 and that have passed through the coin passage 7 without entering the entrance are stored in the notch portion 8B.
Alternatively, the amount of coins sent from the notch 9 to the outer disc 10 and existing at the entrance of the coin passage 7 is reduced, and the coins are smoothly fed into the coin passage 7.

The upper surface of the coin entering the coin passage 7 is pressed by the gripping roller 31, and as described above, the coin is transferred to the transfer belt 32 by the disc drive of the gripping roller 31.
Coins that are sent to the side and enter the lower surface of the transfer belt 32 are sent downstream due to friction with the belt 32.

On the other hand, from the regulating wall portion 6 of the rotating disk 1 to the outer ring disk 10
The coins from the second layer or higher that have overflowed upward and the coins ejected from the ejection notch 7C, the notch portion 8B, and the notch portion 9 reach the guide wall 18 again by the rotation of the outer wheel disc 10, and are again guided by the guide member 19. It is fed onto the rotating disk 1. As a result, rotating disk 1
Approximately equal amounts of coins are always dispersed on the upper and outer discs 10 to ensure delivery to the coin passage 7.

When the amount of coins on the outer wheel disk 10 increases and the coin amount detection switch 48 is activated, the supply disk 50 stops and the supply of coins is cut off, and a certain amount of coins are transferred to the rotating disk 1.
and on the outer race disk 10.

Coins sent through the coin passage 7 and determined to be genuine coins by the discriminators 33, 33 are fed onto a sorting disk 30, where they are sorted by denomination. Note that this denomination-based sorting means may have any other suitable structure.

In this embodiment, the starting end of the passage bottom plate 7A is located on the portion of the fixed wall 4 where the notch portion 8A is formed, but the top surface of the portion where the notch portion 8A is formed is made to be approximately the same plane as the top surface of the rotary disk 1, and this notch portion The upper surface of the 8A forming portion may also be used as the passage bottom plate. Further, the coins on the supply disk 50 may be directly supplied to the rotating disk 1.

6 to 8 show a second embodiment of the present invention, FIG. 6 is a plan view of the embodiment, and FIG.
The figure shows a longitudinal sectional view of the same, and FIG. 8 shows an external perspective view.
In explaining this embodiment, the same reference numerals are used for parts having the same functions as those in the first embodiment.

In FIG. 7, a rotary disk 1 is fixed to a central shaft 3 which is rotatably supported by a machine stand 2, and a rotary disk 1 is rotatably supported at the lower part of the rotary disk 1 by a bearing 51 relative to the central shaft 3. The dish-shaped portion 4A is located,
A fixed wall 4 is provided in a predetermined peripheral area (angular area of approximately 250 degrees) of this dish-shaped portion 4A. A thickness regulating wall portion 6 is formed on the upper surface of the fixed wall 4 and projects upward by a dimension smaller than the thickness of the thinnest coin C to be processed with respect to the upper surface of the rotary disk 1. The remaining region (approximately 110 degree angle region) of the peripheral edge of the dish-shaped portion 4A where the fixed wall 4 is not formed is a cutout portion 8 (see FIGS. 6 and 8). The central shaft 3 is rotated by the rotation of the motor M being transmitted by a rotation transmission mechanism 52 consisting of a pulley, a group of belts, and gears.

In FIGS. 6 and 8, the entrance of the coin passage 7 is located in the notch 8, and in particular, a part of the starting edge of the passage bottom plate 7A is shaped like an arc and is aligned with the periphery of the rotating disk 1. The upper surface is fixed to the machine base 2 so as to be substantially flush with the upper surface of the rotary disk 1. A passage side plate 7B regulating one side of the coin passage 7 is formed from the starting end position of the passage bottom plate 7A toward the downstream side of the passage, and is fixed to the upper surface of the bottom plate 7A. The other aisle side plate 7 that regulates the other side of the aisle
D has a starting end at a position where the width of the passage bottom plate 7A changes from a narrow portion to a wide width portion, is formed toward the downstream side of the passage, and is fixed to the upper surface of the passage bottom plate 7A. The top of the rotating disk 1 located at the entrance of the coin passage 7 and the coin passage 7
Midway position (end position of narrow width part of passage bottom plate 7A)
There is a pulley 35A at the start end and a pulley 35 at the end
A is provided, and a transfer belt 32 is wound between both pulleys. Further, intermediate pulleys 35A, 35A, . . . are provided at appropriate locations between both pulleys. All of these pulleys 35A, 35A, . . . are independently and individually biased downward by springs, and are supported by the support structure 36A so as to be movable up and down. As a result, the lower surface of the transfer belt 32 is placed at a height smaller than the thickness of the coin above the upper surface of the rotary disk 1 and the upper surface of the passage bottom plate 7A, and is raised to the height of the coin thickness when a coin is held in the mouth.

Following this transfer belt 32, there is provided a pulley 35' and a transfer belt 32' around which the starting end is wound.
Discriminators 33, 33 (magnetic sensors in this embodiment) for determining the authenticity and denomination of coins are provided in the installation area of the transfer belt 32'.

In order to feed each coin into the discriminators 33, 33 with sufficient space between them, a rotating disk 1
The peripheral speed of the transfer belt 32, the circumferential speed of the transfer belt 32', and the circumferential speed of the transfer belt 32' are set to increase in this order. The coin passage 7 of this discriminator 33, 33
On the downstream side, a coin sorting section is provided that sorts coins based on the discrimination results of a discriminator (not shown).

Since the fixed wall 4 is supported by a bearing 51 with respect to the central shaft 3, when the rotary disk 1 and the central shaft 3 rotate together, the bearing 51 also rotates accordingly, and as a result, the fixed wall 4 also rotates accordingly. However, when the pin 4C fixed to the fixed wall 4 comes into contact with the stopper 53 on the lower surface of the starting end of the passage bottom plate 7A, the rotation of the fixed wall 4 is stopped and the position is fixed, and the coins are not transferred to the coin passage 7 by the rotating disk 1. The fixed state is maintained during transmission. The reason why the fixed wall 4 is supported by the bearing 51 with respect to the central shaft 3 is to facilitate removal of coins jammed at the entrance of the coin passage 7 or the like. To remove the coin passage 7, the fixed wall 4 is rotated counterclockwise in FIGS. 6 and 8 to widen the gap between the starting end of the passage side plate 7B and the fixed wall 4. The jammed coins at the entrance are dropped onto a collecting disk 10' which will be described later.
The counterclockwise rotation of the fixed wall 4 is stopped by the fixed wall 4 coming into contact with and being locked to a guide plate 54, which will be described later.

The collection disk 10' is fixed to the central shaft 3 at a lower position than the rotating disk 1, and collects coins discharged from the rotating disk 1 over the fixed wall 4 and the side of the passage bottom plate 7A while passing through the coin passage 7. Coins that fall out of the coin passage 7, and coins that reach the notch 8 without being fed into the entrance of the coin passage 7, fall onto the collecting disk 10' and are discharged. The peripheral wall 17 is left with an opening 17A so that the coins on the collecting disk 10' are not ejected outward.
is formed. Also, coins on the rotating disk 1 near the notch 8 are always fed into the collecting disk 10', and coins on the collecting disk 10' near the opening 17A are always removed from the opening 17A. A guide plate 54 is provided to ensure that the liquid is ejected in the same direction.

A chute 55 is provided with its upper end facing the opening 17A at the peripheral edge of the collection disk 10'.
The lower part of the hopper part 56 forms a part of the bottom part of the hopper part 56. Further, between the starting end of the passage side plate 7D and the peripheral wall 17 on the side of the passage bottom plate 7A, there is a space between the passage bottom plate 7A and the peripheral wall 17.
A guiding guide 57 for guiding coins falling from the side of A to a chute 55 is fixed. This hopper section 56 is used to input and store coins brought in by the machine operator from elsewhere (referred to as original coins), and since the hopper section 56 is also equipped with a chute 55, the collection disk can be opened at 10 degrees. The ejected coins (returning coins in the original filling coins) are also stored in the hopper section 56 together with the original filling coins.

A replenishment conveyor 58 is provided in the hopper section 56 diagonally upward from the bottom thereof, and coins are cut into pieces by a large number of protrusions (not shown) formed on the surface of the replenishment conveyor 58 and transported upward. It is then led out and replenished through the chute 59 to the center of the rotating disk 1. A spiral guide wall 60 is provided on the rotating disk 1 and is fixed to a support arm 61 fixed to the machine base 2 so as to face close to the upper surface of the disk 1. Then, by the chute 59, the rotating disk 1
The coins supplied to the rotating disk 1 are guided to the periphery of the rotating disk 1 by the centrifugal force of the rotating disk 1 and the guide wall 60.

Next, the operation of the above embodiment will be explained.

When the machine operator inserts the original coins into the hopper section 56 and presses the start button of the machine, the coins in the hopper section 56 are transferred upward by the supply conveyor 58 and led out to the center of the rotating disk 1 through the chute 59 to be supplied. Ru. The coins supplied to the center of the rotating disk 1 are moved outward by the centrifugal force of the rotating disk 1, and are guided by the guide wall 60 to reach the fixed wall 4. At this point, the fixed wall 4 is in a fixed state where the pin 4C is in contact with the stopper 53, and the first layer of coins is regulated and guided by the fixed wall 4 and reaches the entrance of the coin passage 7, where it reaches the starting end. The coin is held under the transfer belt 32 of the pulley 35A and fed into the coin passage 7. Among the coins sent into the coin passage 7, coins in an unstable position with a part of the starting end resting on the passage bottom plate 7A are directly passed through the collecting disk 10' or the guiding guide 57 while being transferred through the passage 7. It is discharged to the chute 55. The coins in a stable posture transferred through the coin passage 7 are spaced apart when being transferred from the transfer belt 32 to the transfer belt 32', and when they pass through the discriminators 33, 33, the authenticity and denomination are discriminated. The coins are then sent to the coin sorting department, where they are sorted by denomination.

Further, coins that have passed from the rotary disk 1 into the coin passage 7 without being sent into the coin passage 7 are regulated by the guide plate 54 and fall from the notch 8 onto the collection disk 10'.

The coins of the second and higher layers guided by the guiding wall 60 and reaching the fixed wall 4 by the centrifugal force of the rotating disk 1 pass over the fixed wall 4 and fall onto the collecting disk 10'. Since this collection disk 10' rotates integrally with the rotating disk 1, the coins discharged onto this disk 10' are moved to the peripheral edge by centrifugal force, and
7, passes through the lower part of the coin passage 7, and is discharged from the opening 17A to the chute 55.

Among the coins on the collection disc 10' (coins from the second layer or higher that have crossed the fixed wall 4 and coins that have fallen from the side of the passageway 7 to the collection disc 10'), the coins that have reached the guide plate 54 are also It is deflected by the guide plate 54 and is forcibly discharged from the opening 17A by the centrifugal force of the collecting disk 10'. In this way, the collection disk 10'
All coins ejected upwards and guidance guide 5
The coins discharged through 7 are sent to the hopper section 56 through the chute 55, and then transferred to the supply conveyor 5.
8. It is sent onto the rotating disk 1 again through the chute 59.

This embodiment is largely different from the first embodiment in that the coin recirculation means includes a collection disk 10', a peripheral wall 17,
guide plate 54, chute 55, hopper part 56,
It is constituted by a conveyor 58 and a chute 59, and the fixed wall 4 can rotate around the periphery of the rotary disk 1 within a predetermined angle range, and remains in a fixed state during operation.

Therefore, the present invention is not limited to the first and second embodiments, for example, the fixed wall 4 of the first embodiment is also rotatable in the direction in which the discharge notch 7C widens at the periphery of the rotating disk 1, so that the discharge notch 7C is expanded during operation. The discharge notch 7C of the first embodiment is rotated in the direction in which the discharge notch 7C is narrowed.
It may be set to a fixed state when it is moved to position C. Further, in the first embodiment, the notch 8
B. A notch 9 is formed to release coins that have passed the entrance of the coin passage 7 into the outer wheel disc 10, but there is also a thickness regulating wall 6 in this area with a height lower than the thickness of the coins to be processed. may be formed. Alternatively, in order to leave all the coins in the rotating disk 1, it may be a fixed wall with a height that the coins cannot jump over.

Furthermore, although the guide member 19 of the first embodiment is set to a height that allows it to pass over the third or higher layer of the thinnest coin, it is not limited to this.
This guide member 19 depends on whether the amount of coins sent from the rotating disk 1 to the rotary disk 1 is set to be large or small.
The height may be arbitrarily selected.

〔Effect of the invention〕

As explained above, the coin dispensing device according to the present invention includes a rotating disk that moves supplied coins to the periphery by centrifugal force, and a machine that is located along the periphery of the rotating disk and is kept in a fixed state at least during operation. a thickness regulating wall that is supported on the side and whose height from the surface of the disk is lower than the thickness of the coins to be processed and allows the second layer of coins to overflow; a fixed wall having a notch for ejecting coins to the fixed wall; and a passage bottom surface provided facing the notch of the fixed wall and substantially flush with the surface of the rotating disk, and for receiving coins released from the notch. By adopting a configuration that includes a coin passage for conveying and a coin recirculation means that receives coins that have passed through the thickness regulating wall portion of the fixed wall and sends them back onto the rotating disk, this configuration is essential in conventional devices of this type. It is now possible to send coins with extremely different thicknesses from a mixed state to a layered state into a coin passage, which was impossible with the coin thickness regulating member that was used as a member. Compared to a system in which a rotating disk having two surfaces is used and the stepped portion of both surfaces is used as a boundary wall to regulate the thickness, there is no need to provide a coin passage diagonally upward from the first surface. , the surface of the rotating disk and the bottom of the coin passage can be made almost flush, which allows the coins to be stably fed into the coin passage in a constant posture, which eliminates the problem that occurs with the above conventional configuration. This eliminates the problem of coins flying around and jamming coins, and has various effects such as increasing processing speed and efficiency.
