Description

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

[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. The coin is also provided with a thickness regulating member for regulating the thickness direction of the coin. The thickness regulating member is installed at a position slightly higher than the thickness of the coin to be processed,
It has the function of allowing only one coin to enter under the thickness regulating member and leading to the coin passage, and preventing two coins from entering the coin passage. 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 selection 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 will enter in double stacks, or the thickness regulating member will pass through. This is because it gets stuck between it and the top surface of the rotating disk. Therefore, in this type of conventional coin dispensing device,
It had the disadvantage that it could only be used for counting or sorting coins of denominations of similar thickness, and the range of use was severely limited. Furthermore, even when counting coins of one denomination, if deformed coins or other thick coins are mixed in, these coins can become jammed 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 is left on the first surface portion, and the coins of the second and higher layers are transferred onto the second surface portion, thereby forming a single layer.

The coins that were further regulated by the boundary wall were the first
The coins are sent into the coin passage facing the surface and taken out.
Further, the coins transferred to the second surface portion side are returned to the first surface portion again by a coin guide member provided on the second surface portion. By doing this, the various drawbacks of the conventional method could be overcome to some extent, but the following other problems arose.

That is, the first problem with this device is that
Since the coins transferred onto the second surface are always sent back to the first surface by the coin guiding member,
Coins in the second or higher layer attempting to migrate from the surface part to the second surface part are obstructed by coins returned from the second surface part to the first surface part by the coin regulating member,
There is no smooth transition onto the second surface. Also the second
The coin returned from the surface part to the first surface part is placed on top of the coin that was on the first surface part to form a two-layer coin, and the coin thus formed in two layers is transferred to the second surface part. Before it was finished, I reached the entrance of the coin passage, and 2
Sometimes the coins are fed into the coin passage with their weight intact.
As a result, coins get jammed when the coins are caught under the coin feeding rollers provided at the entrance of the coin passage or the coin transporting belt.

A second problem with the above device is that since the boundary wall between the first surface portion and the second surface portion is used to regulate the thickness, the coin passage is inclined diagonally upward from the first surface portion. This is due to the fact that the In other words, this coin passage is equipped with rollers and transfer belts as described above.
When the coins layered on the boundary wall move from the first surface to the bottom of the coin passage, the coins change their posture diagonally upward in an unstable state, so when changing their posture, the rollers and belts The pulley will get stuck in it. Therefore, if the timing of putting a coin in its mouth is even slightly delayed, both that coin and the next coin will be caught in its mouth at the same time, resulting in a coin jam. In this way the first
There is a problem of coin jamming caused by the bottom surface of the coin passage being inclined with respect to the surface portion.

[Purpose of the invention]

The present invention has been made for the purpose of solving the above-mentioned problems of the prior art. The present invention provides a coin dispensing device that can solve the first and second problems.

[Embodiments of the invention]

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

Figures 1 to 5 are the first embodiment of the present application, and show the first and second embodiments of the invention, and Figures 6 to 11 are the second embodiment of the present invention, and show the first and second embodiments of the invention. , shows an embodiment of only the first invention.

In FIG. 1, the first disk 1 has a gentle conical shape at the center of its upper surface, and the center portion of the first disk 1 is fixed to a central shaft 3 that is rotatably supported on the machine stand 2 side. .

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

As shown in FIG. 2, the fixed wall 4 is approximately 1/2
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 first disc 1 to the downstream side in the rotational direction of the first disc 1 are defined as notches 8 and 9.

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 first 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, this passage bottom plate 7
The top surface of A is almost the same as the top surface of the first disk 1. Furthermore, the fixed wall portion where the notch surround 8B is formed is flush with or slightly lower than the upper surface of the first 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 allow the release of 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 the inclined surface of the notch 9 forming portion will be explained later when the coin guiding member 20 is explained.

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 part of the coin passage 7 stall at the entrance part, some of the coins are ejected outward from the ejection notch 7C before the entrance part of the coin passage 7. This prevents coin jams caused by coins stagnation in the machine.

A second disk 10 is provided on the outer periphery of the fixed wall 4 and constitutes a coin circulation means for circulating the coins C onto the first disk 1. This second disk 1
0 is placed in an inclined position so that the starting end 6A side of the regulating wall 6 of the fixed wall 4 is high and the ending end 6B side is low, and the low part of the second disk 10 (the part on the ending end 6B side) is placed in the coin passage 7. The pins 13 , 13 on the outer periphery of the support member 12 are positioned downward, and are further supported on the outer periphery of the boss portion 4</b>B of the fixed wall 4 via bearings 11 , 11 , and the body portion of the second disk 10 . 1
The support member 12 and the second disk 10 are connected by fitting into elongated holes 14, 14 whose lower ends are open and whose width is slightly larger than the diameter of the pin 13 formed at 0A.

In this example, the high part of the second disk 10 (the part on the starting end 6A side) is located at the terminal end 9 of the notch 9 of the fixed wall 4.
Although it is located at a slightly higher position than the B forming part and the upper surface of the rotating disc 1, it may be located at a lower height as long as it does not hinder coin feeding from the second disc 10 to the first disc 1. These pins 13, 13 and long hole 1
4 and 14 are provided at two symmetrical positions as shown in FIG.
The degree of inclination of the second disc 10 with respect to the support member 12 is adjusted.

The outer periphery of the second disk 10 is supported by a plurality of support plates 15, 15, . 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 second disc 10 with respect to the support member 12, each guide roller 16, 16
The degree of inclination of the second disc 10 is determined by pinching and holding the peripheral edge of the second disc 10.

Around the second disk 10, a support plate 15 and a
5' (see FIGS. 1 and 4) is provided with a circumferential wall 17 of constant radius;
Subsequently, a coin guide member 20 for returning the coin C on the second disk 10 onto the first disk 1 is extended.

The coin guiding member 20 includes a guiding wall 18 that extends in an arc from near the starting end 9A of the region Z of the notch 9 to the near center in the radial direction on the second disk 10 in the direction of the ending end 9B, and It is constituted by a guide portion 19 fixedly positioned between the tip and the vicinity of the end 9B of the notch 9 forming portion of the fixed wall 4. The height of the guide wall 18 is set to be sufficient to prevent coins from flying out to the outside, whereas the guide portion 19 that approaches the periphery of the coin placement surface 1a of the first disk 1 has several layers. In other words, the height of the thinnest coins (e.g. 1 mm) is set so that the coins in the third and higher layers can pass through (e.g. 1.8 mm), and are placed on the first disk 1. The amount of coins sent is controlled.

The coin guide member 20 extends radially inward on the second disk 10 in an arc shape from near the starting end 9A of the notch 9 toward the ending end 9B. Therefore, the guide wall 1
The distance between the guide portion 8 and the guide portion 19 and the portion of the fixed wall 4 where the cutout portion 9 is formed becomes narrower in the direction of rotation of the second disk 10. Therefore, when the outer circumference side coin on the second disk 10 and the inner side coin move side by side, a jam occurs between the guide wall 18 or the guide part 19 and the notch 9 forming part of the fixed wall 4. It is assumed that Therefore, the notch 9 of the fixed wall 4
By forming the formed part into an inclined surface, coin jamming can be eliminated and coins can be smoothly fed into the first disk 1.

The driving force transmission system to the first disk 1 and the second disk 10 is, as shown in FIG. A gear 23 is meshed with a gear 24 on the central shaft 3 to impart rotation to the central shaft 3, and another gear 25 on the central shaft 3 is fixed to the outer periphery of the boss portion of the support member 12. It is designed to be applied to the gear 26 which is rotated through intermediate gears 27 and 28 which are pivotally supported on the machine base 2. Note that 29 is a pulley for imparting rotation to a farewell 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 peripheral edge of the first disk 1 is rotated at a circumferential speed that is equal to or faster than the circumferential speed of the inner circumferential wall (near the fixed wall 4) of the second disk 10, and the second disk 10 The top coin smoothly moves to the first
It is designed to be placed on top of disk 1.

As schematically shown in FIG. 1, the coin passage 7 includes a passage bottom plate 7A provided on almost the same surface as the upper surface of the first disk 1, and a coin gripping roller 31 provided on the entrance of the passage bottom plate 7A. , 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 and the pulleys 35, 35, . ,35
... are suspended by springs 37, 37....

The gripping roller 31 and the transfer belt 32 are positioned at a height smaller than the thickness of the thinnest coin, and are adapted to rise to the thickness height according to the thickness of the coin entering.

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 feed interval between coins when transferring them to the transfer belt 32 due to the difference in diameter of the coin C. The automatic transmission mechanism 38 is equipped with an automatic transmission mechanism 38. That is, coin C
When the coin is thick, it is treated as a large coin and the number of revolutions is increased, and when it is thin, the number of revolutions is lowered and sent out.

In a specific example, as shown in FIG. 5, a piece 39 inserted into the support structure 36 and inserted into the shaft 34 of the roller 31 is supported by a horizontal shaft 40 in a direction perpendicular to the shaft 34. Insertion roller 31
is supported movably in the direction of arrow P, and this shaft 34
A variable speed roller 41 that bulges out in an arc shape is fixed to the other end. Further, another shaft 42 is provided on the support structure 36, and a piece 43 inserted therein is swingably supported by a horizontal shaft 44 in a direction perpendicular to the shaft 42. A tapered roller 45 having a taper in a direction opposite to that of the speed change roller 41 is fixed so as to partially contact the circumferential surface of the speed change roller 41, and 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.

Therefore, if the coin C that enters under the gripping roller 31 is thick, the gripping roller 31 will be pushed up greatly against the elastic force of the elastic ring 47, so the contact point between the speed change roller 41 and the tapered roller 45 will be Moving to the left in the figure, the large diameter side of the tapered roller 45 contacts the small diameter side of the speed change roller 41, increasing the speed and transmitting rotation to the gripping roller 31. In the case of thin coins, on the other hand, the amount of push up of the gripping roller 31 is small, so the small diameter side of the tapered roller 45 and the large diameter side of the variable speed roller 41 contact, and the coin is decelerated to the gripping roller 31. Rotation can be transmitted.

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.

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

The coins C supplied onto the second disk 10 through the supply rotation 50 are sent by the rotation of the second disk 10 in the direction of the arrow, and are sent along the coin guiding member 20 to the first disk.
It is brought to the disk 1 side. For coins that overlap in three or more layers near the first disk 1, the coins in the first or second layer of the lowest layer are moved toward the first disk 1 by the guide part 19, and the coins in the third or higher layer are The coin passes over the guide part 19 and moves onto the second disk 10 again,
The first or second layer of coins is transferred onto the first disk 1. As a result, with respect to the coins fed onto the first disk 1 and moving toward the thickness regulating wall 6, a large amount of coins are not fed into the upper part from the second disk 10 side, and the coin passage 7 The thickness regulating wall portion 6 ensures that the coins are layered in one layer before reaching the entrance. The height of this guide portion 19 is determined by the maximum height (for example, the thinnest coin thickness 1
It is also possible to set the height dimension to 2.8 mm, which allows coins to pass through the fourth layer or higher for millimeter, or to pass through the second or higher layer of the thinnest coins if the main effort is not focused on increasing efficiency. Dimensions (e.g. thinnest coin thickness 1
0.8 mm height). In addition, when the notches 8 and 9 are formed as in this example, and the coins that do not enter the coin passage 7 are released into the second disk 10 in principle, the height of the guide portion 19 should be relatively high. , it is preferable that the size is such that a large amount of coins can be sent.

The first or second layer of coins C gathered by the coin guiding member 20 are sent onto the first disk 1 from the inclined surface 9 of the fixed wall 4.

Coins C that have entered the first disk 1 move along the inner circumference of the fixed wall 4 due to centrifugal force, and coins in the second and higher layers in the area X of the regulating wall 6 are sent out onto the second disk 10 again. Then, only the coins of the first layer enter the coin passage 7 through the notch 8 corresponding to the entrance of 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 rotation 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 part 6 of the first disc 1 to the second disc 1
Coins from the second layer or higher that overflowed to 0 are
The second disk 10 rotates to reach the guiding member 20 again, and is sent onto the first disk 1 again by the guide section 19. As a result, on the first disk 1 and on the second disk
Approximately equal amounts of coins are always dispersed on the disk 10 to ensure delivery to the coin passage 7.

When the amount of coins on the second disk 10 increases and the coin amount detection switch 48 is activated, the supply disk 50 is stopped and the supply of coins is cut off, so that a certain amount of coins remains on the first disks 1 and 10. done to.

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.

Next, a second embodiment will be explained with reference to FIGS. 6 to 11, using the same reference numerals for parts common to those in FIGS. 1 to 5.

The first disk 1 and the second disk 10 in this embodiment
is composed of the same rotating disks 100, the portion corresponding to the first disk 1 is referred to as a first surface portion 1A, and the portion corresponding to the second disk 10 is referred to as a second surface portion 10A, and these first and second surfaces A regulating wall portion 6 is formed at the boundary between portions 1A and 10A. As shown in FIG. 7, the height of the regulating wall portion 6 is formed in a stepped shape that is slightly lower than the thickness of the thinnest coin among the coins to be processed.

The first surface portion 1A has a plurality of grooves 51, 51, 51 having an inverted trapezoidal cross-sectional shape around the central axis 3 as shown in FIG.
is formed in a ring shape.

The coin passage 7 is made up of a coin passage member forming a coin passage surface and a carrier for transporting the coins C. In the illustrated embodiment, the coin passage surface consists of three coin passage members 7A made of plate-like materials, 7A and 7A in parallel, and coins are placed around the rotating disk 100 from the second surface portion 10A on the side surface of the substrate 52, which is fixed to the aircraft body so as to straddle one side of the rotating disk 100. In order to prevent C from flying out, it is fixed by mounting shafts 53, 53, 53 at a plurality of locations (three locations in the figure) in an upwardly inclined position extending outwardly over a peripheral wall 17 that is fixedly provided to prevent C from flying out.

The tips of the coin passage members 7A, 7A, 7A are
As shown in an enlarged view in FIG. 8, it is formed into a pointed shape, and the lower surface of the tip is formed with an edge portion 7A' that fits into the grooves 51, 51, 51, and this edge portion 7A' forms the bottom of the groove 51. The coin passage members 7A, 7A, 7A are fitted from the tangential direction of the grooves 51, 51, 51 so as to be as close as possible to the coin passage members 7A, 7A, 7A, so that the upper surfaces of the tips thereof are smoothly connected to the first surface portion 1A.

A transfer belt 32 is provided on the upper surface of the coin passage member 7A located at the center of the coin passage 7. In this transfer belt 32, a pulley 54 on the rear side of the coin passage 7 is supported by a shaft 55 on the base plate 52, and a motor _M1 is rotatably coupled to this shaft 55, so that the pulley 54 is rotated in the direction of the arrow. The shaft 55 is also movable up and down to follow the thickness of the coin C, although details are not shown, and the vertical position can be adjusted as necessary.

The pulley 56 on the tip side of the coin passage 7 is pivotally supported by the tip of the lower arm portion 57a of an L-shaped arm 57 whose intermediate portion is pivoted to the substrate 52 by a shaft, and the pulley 56 is connected between the upper arm portion 57b and the substrate 52. A tension spring 58 is tensioned therebetween to bias the pulley 56 in the direction of the coin passage member 7A.

Note that on the upper surface of the belt 32 on the lower running side between the pulleys 54 and 56, presser rollers 61 and 62 supported by lower arm portions 59a and 60a of L-shaped arms 59 and 60 similar to those described above are supported by springs 63. ,64
The belt 32 is pressed into contact with the belt 32 by the force applied thereto, thereby preventing the belt 32 from floating up.

The passage width of the coin passage 7 is determined by the arrangement interval of the three coin passage members 7A, 7A, 7A, but both sides are in a free state, and the width between the coin passage members 7A, 7A on both sides is The spacing is configured to approximately match the smallest diameter among the coins to be processed. In this case, one side may be restricted by the substrate 52, and only the other side (rotation center side) may be left in a free state.

The coin guide member 20 is located downstream of the coin passage 7 in the rotational direction of the rotary disk 100, and has a base that smoothly extends to the inner surface of the peripheral wall 17 and gradually extends to the second side.
It is formed in an arc shape that extends diagonally across the surface portion 10A to the vicinity of the regulating wall portion 6, and the portion approaching the first surface portion 1A has a height that allows coins in the upper layer of coins to pass through. It is formed in the guide portion 19 of the side. In this example, the height of the guide portion 10 is 1.8 mm for the thinnest coin thickness of 1 mm,
Coins from the third layer and above pass through, and coins from the first and second layers are guided to the first surface portion 1A.

The lower end of the coin guide member 20 is held close to the upper surface of the second surface portion 10A by a support member 65 fixed to the machine stand 2.

The rear end of the coin passage 7 is connected to a coin counting passage, a coin sorting passage, etc. depending on the purpose of use, or the coin passage 7 itself is provided with a counting or sorting mechanism for use.

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

Coin guide member 20 on rotating disk 100, peripheral wall 1
7. When a coin C is supplied by an appropriate means into the area formed by the support member 65 (indicated by a white arrow), the centrifugal force caused by the rotation of the rotating disk 100 causes the coin C to move in the direction of its outer circumference.

When the coin C hits the coin guide member 20 as the rotating disk 100 rotates, the coin C hits the second surface portion 10A.
However, when approaching the first surface portion 1A, the coins in the third and higher layers are moved toward the second surface portion 10A by centrifugal force due to the guide portion 19, and the coins are further guided into the first surface portion 1A. Alternatively, only the second layer coins are guided to the first surface portion 1A side.

The coin C that has entered the first surface portion 1A in this way is moved toward the outer circumference again by the centrifugal force of the first surface portion 1A, but the coin C that is on the surface portion 1A is Since it hits the stepped regulation wall 6 at the boundary with the second surface 10A, it cannot move to the second surface 10A and moves along the regulation wall 6 as it is. Also, the first surface portion 1A
The top coin C, which is double stacked above, is the 7th coin.
Since it does not hit the regulating wall part 6 as shown in the figure, it moves again onto the second surface part 10A under the action of centrifugal force.

Therefore, within the first surface portion 1A of the rotating disk 100, there are coins C arranged one after another, and two coins C are arranged side by side.
It cannot exist in a state where it becomes heavy.

In this way, as the rotating disk 100 rotates, when the coin C on the first surface portion 1A reaches the tip of the coin passage 7, it moves from the tip of the coin passage members 7A, 7A, 7A onto the coin passage 7 as shown in the eighth figure. The upper surface of the coin is transferred to the belt 32 of the pulley 56 portion, and the coin is conveyed toward the rear on the coin passage members 7A, 7A, 7A. In this case, the arm 57 supporting the pulley 56 is often rotated clockwise against the pulley 58 to accommodate the difference in the thickness of the coin C, so that the coin C is taken in regardless of the difference in thickness, and the subsequent presser roller 61, 62, and pulley 54 are also followed in the same manner.

The coin C on the second surface part 10A is in the coin passage 7
The coins pass under the coin guide member 20 again and are guided onto the first surface portion 1A in the same manner as described above, where they are lined up one by one and sent to the tip of the coin passage 7.

The coin C conveyed through the coin passage 7 is conveyed to the next process with its both ends left as it is, regardless of its outer diameter.

FIG. 10 shows a modification of the present invention. In the case of the above embodiment, the first and second surface portions 1A, 10
Since A is formed of a rotating disk 100 made of the same material, the circumferential speeds of the first and second surface portions 1A and 10A are different, and the circumferential speed of the second surface portion 10A is higher, so that the coin C is inevitably The first,
This is an embodiment in which the second surface portions 1A and 10A are constructed from separate members, and each is rotated at a different number of rotations.

That is, the rotating disk 100 mainly includes the first disk 1 constituting the first surface portion 1A and the second disk 1 mainly forming the first surface portion 1A.
The second disc 10 constitutes the surface portion 10A.

The regulating wall portion 6 in this embodiment is formed near the periphery of the first disk 1 constituting the first surface portion 1A, and outward from the regulating wall portion 6 is the second surface portion 10A of the surface of the second disk 10. are connected on the same plane.

Since the other configurations are the same as those of the previous embodiment, the explanation thereof will be omitted.

By configuring as in the above embodiment, the first
Since the surface portion 1A rotates faster than the second surface portion 10A, too many coins C will not accumulate on the second surface portion 10A.

Regarding the configuration of the rotating disk 100, other modifications as shown in FIGS. 11A to 11E are possible.

That is, FIG. 11A shows the basic configuration example shown in FIG. This is a case where the smoothness of movement in the direction of the regulating wall section 6 on the surface section 1A is increased. In addition, in FIG. 11C, the second surface portion 10A is also formed into a medium-height shape that slopes downward in the outer circumferential direction, so that there is no congestion of coins C near the regulating wall portion 6.

FIG. 11D shows a modification of the rotating disk 100 in the modified embodiment shown in FIG. Regulation wall part 6 on the inner peripheral surface of 10
This is the case when it is made to form. Furthermore, the 11th
In Figure E, a second disk 10 formed in an annular shape is provided on the periphery of the first disk 1 so as to be overlapped, and a regulating wall 6 is formed at the inner peripheral edge of the second disk 10, and the transmission of the disk is controlled between the first and second disks. Gears 77, 78 on the outer peripheral surfaces of 1 and 10
This is a case where a method is adopted based on etc. As in the first embodiment, the height of the guide portion 19 in this embodiment can be set to any value within a range that ensures that the coins are layered in one layer before reaching the entrance of the coin passage 7. Needless to say.

〔Effect of the invention〕

As explained above, the coin dispensing device according to the present invention includes a first disk portion that moves supplied coins to the periphery by centrifugal force, and a coin dispensing device located at the periphery of the coin placement surface of the first disk portion. , a thickness regulating wall portion having a height lower than the thickness of the coin to be processed from the placement surface and allowing coins to pass through the second or higher layer; and a thickness regulating wall portion on the coin placement surface of the first disk portion. a coin passage section that receives and conveys coins; a second disk section that moves coins from a second or higher layer that have passed through the thickness regulating wall; and a coin on the second disk section that returns the coins onto the first disk section. This coin guiding member has a coin guiding member for
The coin guide member is arranged in close proximity to the upper surface of the second disc part so as to diagonally cross the second disc part, and at least a portion of the coin guiding member that approaches the periphery of the coin placement surface of the first disc part is stacked in several layers. Since the guide section is provided with a height that allows the upper layer of coins to pass through, it is possible to reliably feed coins one by one to the coin passage without using a coin thickness regulating member, which was conventionally considered an essential component. Since it does not have a coin thickness regulating member, there are no coin jams due to coins getting caught, and it has various excellent effects such as smooth delivery.
