Abstract

PROBLEM TO BE SOLVED: To increase a range of diameters of coins that can be dispensed in a coin dispensing device which can dispense the coins with diameters within a predetermined range without requiring any kind of adjustments such as exchanging of components.SOLUTION: Coins drop into through holes one by one when a rotary disk rotates in a normal direction and are sorted. The coin is pushed by a pushing body on a lower surface and also guided by a circular coin guiding wall of a housing hole, and thereafter, is guided by an outlet rotary body forming an outlet guide along the circumferential direction of the rotary disk toward a flicking unit to be flicked out by a flick out roller. When the coin gets jammed, the rotary disk is rotated in a reverse direction and the coin pushed by a rear tip end of the pushing body is guided by the circular peripheral surface of the outlet rotary body. Because of a shape of the circular peripheral surface, a pressing force by a pressing body and a reaction force from the outlet rotary body form a large angle, and this causes the coin to move back into the housing hole and allows the continuous reverse rotation, and clears the coin jam.

The present invention relates to a coin dispensing device that can dispense coins having different diameters one by one.
In particular, the present invention relates to a coin dispensing device that can dispense coins having widely different diameters one by one.
Furthermore, the present invention relates to an inexpensive coin dispensing device capable of dispensing coins having widely different diameters one by one.
The “coin” used in this specification includes a coin as a currency and a token as a substitute coin such as a medal.

Conventionally, when a large number of coins held in a loose state in a holding bowl are dispensed one by one using a rotating disk arranged in the bottom hole of the holding bowl, the coins are rarely used as a rotating disk and a holding bowl or a rotating disk and a base. A coin jam occurs that stops the rotation of the rotating disk, so that the coin jam is automatically resolved. The disc has been reversed.
There has also been proposed a coin dispensing apparatus that can dispense coins having a diameter in a predetermined range without changing parts and adjusting the position.
As shown in FIG. 13 (only necessary codes are shown) as a conventional technique for reversing the rotating disk when coins with a diameter within a predetermined range are generated and a coin jam occurs, a fixed base plate (2) that forms the surface of the mounting base (1) And a rear curve interposed between the coin receiving holes (9) adjacent to each other from the back surface of the disk rotor body (6) having a plurality of coin receiving holes (9) opened in an overall radial symmetrical distribution type. Similarly, a coin-carrying perforated disk rotor (D) provided with a wing (11) and a reversible motor (4) for rotating the perforated disk rotor attached to the back surface of the base plate (2). A coin receiving hopper (H) which is detachably attached to the surface of the base plate (2) and surrounds the peripheral edge of the perforated disc rotor (D); A coin outlet (17) cut out as a constant opening width (W1) in a part facing the coin conveyance path (G) by the rotation of the perforated disk rotor (D) in the container hopper (H); A coin payout passage (21) shaped in a tunnel shape directly connected to the coin outlet (17) of the coin receiving hopper (H) by a coin count sensor cradle (M) attached and fixed to the surface of the base plate (2). ) And the coin outlet (17) and the coin payout passage (21) facing each other, the perforated disk rotor (D) is placed so as to face the downstream side in the forward direction of rotation (F). The above-mentioned perforated disclosure between the separated roller (36) and the coin outlet (17) and the coin payout passage (21) facing each other. -(D) is installed so as to face the upstream side in the forward direction (F) in which it rotates forward and the opening width (W2) facing the separate roller (36) is kept narrower than the diameter of the smallest coin (Cs). The coin payout roller (35) biased in this way and the surface of the base plate (2) protrude from the surface of the perforated disk rotor (D) to the coin transport path (G), and the coin (Cl) ( And a coin receiving hole (17) for guiding Cs) from the coin outlet (17) toward the coin payout passage (21), and a coin receiving hole of the disc rotor body (6) from the coin receiving hopper (H). The coin (Cl) (Cs) received in (9) is pushed forward and carried by the rear curved blade (11) of the perforated disk rotor (D) rotated forward in one direction (F). And, in the hopper coin payout device for paying out the coins outlet from (17) to the coin payout passage (21),
The smallest coin (Cs) pushed forward in one direction (F) by the backward curved blade (11) of the positively rotating perforated disk rotor (D) is now the front convex curved surface (12f) of the rear curved blade (11). And the discharge roller (35) and the upstream opening edge of the coin outlet (17) at the first to third contacts (P1), (P2), and (P3). The virtual straight line (ZZ) connecting P1) and (P2) is biased outward by a fixed distance (L1) from the center (O) of the smallest coin (Cs).

The first contact point (P1) of the payout roller (35) and the upstream opening edge of the coin outlet (17) at the first to third contacts (P1) (P2) (P3). , And the rotation circle trajectory of is biased outward by a certain distance (L2) from the center (O) of the smallest coin (Cs),
Moreover, the opening width (W3) facing the third contact (P3) forming the upstream opening edge of the coin outlet (17) and the separation roller (36) located on the downstream side is the maximum coin (Cl). To be wider than the diameter,
The upstream opening edge of the coin outlet (17) is shaped as a coin guide wall surface (58) formed of a smooth concave curve or straight line until it circumscribes the circular inner peripheral surface of the coin receiving hopper (H). A featured hopper type coin payout device is known (see Patent Document 1).

Japanese Patent No. 4343199 (FIGS. 1 to 6, paragraph numbers 0025 to 0053)

In the prior art described above, in order to guide the minimum coin Cs so as to be scraped into the circular coin transport path G when the perforated disc rotor D rotates in the reverse direction, the minimum coin Cs is used as the contacts P1 to P1. In the case of contact with P3, the center o of the minimum coin Cs is biased outward by a certain distance L2 from the rotation circle locus of the contact P1, in other words, the center o of the minimum coin Cs is more than the rotation circle locus of the contact P1. Since it is indispensable to be shaped as a coin guiding wall surface 58 that is located inward by a certain distance L2 and is formed of a smooth concave curve or a straight line until it circumscribes the circular inner peripheral surface of the coin receiving hopper, at least constant There is a problem that the diameter of the smallest applicable coin is narrowed by the distance L2 and the applicable coin range is narrow.
This is because the resultant force F3 of the pressing force F1 acting on the minimum coin center o from the rear concave curved surface 12r and the reaction force F2 from the coin guiding surface 58 slides (frictions) between the minimum coin Cs and the coin guiding surface 58. This is because it is necessary to overcome the resistance R, so that a resultant force F3 of a predetermined value or more is obtained.
Therefore, since the diameter of the minimum coin Cs is always a diameter obtained by adding the fixed distance L2, there is a problem that the application range of the coin diameter is limited.

A first object of the present invention is to provide a coin dispensing device having a wide application range of coin diameters.
The second object of the present invention is that it is not necessary to add the fixed distance L2, in other words, the case where the center of the coin is located outside the rotation circle locus of the first contact P1 of the backward curved wing. It is also to provide a coin dispensing device that can reverse the rotating disk. In other words, even if the center of the coin is located outside the rotation circle locus of the first contact P1, a coin dispensing device that can return the coin into the storage hole by reversing the rotating disk is provided. That is.
The third object of the present invention is inexpensive and stores coins when the rotating disk is reversed even when the center of the coin is located outside the rotational circle locus of the first contact P1 of the backward curved wing. It is to provide a coin dispensing device that can be returned to the inside of a hole.

In order to achieve this object, the first invention according to claim 1 is configured as follows.
A coin is dropped into a through hole formed in an eccentric position of a rotating disk rotating in a circular storage hole, and the coin is pushed by a pushing front surface of a pushing body extending in a circumferential direction of the rotating disk below the rotating disk. While pushing the coin guide wall of the storage hole while moving it on the base, the pusher of the pusher is pushed while guiding the coin guide wall to the outlet guide extending in the circumferential direction of the rotating disk following the coin guide wall. After being pushed by the moving front surface, it is ejected by a fixed body and an ejection roller elastically biased so as to approach the fixed body, and the coin is pushed by the back surface of the pushing body when the rotating disk is reversed. In the coin dispensing apparatus which is guided along the outlet guide and then returned to the storage hole, the outlet guide has an outlet whose circular peripheral surface is rotatable about an axis. A coin dispensing apparatus characterized by being configured by rolling bodies.

According to a second aspect of the present invention, a coin is dropped into a through-hole formed at an eccentric position of a rotating disk that rotates in a circular storage hole, and a push extending in the circumferential direction of the rotating disk is provided below the rotating disk. An outlet extending in the circumferential direction of the rotating disk following the coin guide wall at the coin outlet while being guided by the coin guide wall of the storage hole while being pushed by the pushing front surface of the moving body. After being pushed by the pushing front surface of the pushing body while being guided by a guide, the pushing body is ejected by a fixed body and a spring roller elastically biased so as to approach the stationary body, and when the rotating disk is reversed, the pushing body In the coin dispensing device adapted to push the coin by the back surface and guide it along the exit guide, and then return it to the storage hole,
A coin dispensing device characterized in that the exit guide is constituted by a roller.

According to a third aspect of the present invention, a coin is dropped into a through hole formed at an eccentric position of a rotating disk that rotates in a circular storage hole, and a pressing member that extends in the circumferential direction of the rotating disk below the rotating disk. An outlet extending in the circumferential direction of the rotating disk following the coin guide wall at the coin outlet while being guided by the coin guide wall of the storage hole while being pushed by the pushing front surface of the moving body. After being pushed by the pushing front surface of the pusher while being guided by a guide, the pusher is ejected by an ejection roller elastically biased so as to approach the fixed body and the fixed body), and when the rotary disk is reversed, the pusher is pushed. In the coin dispensing device adapted to push the coin by the back surface of the moving body and guide it along the exit guide, and then return the coin into the storage hole.
When the coin with the smallest diameter comes into contact with the back surface, the ejecting roller, and the outlet guide during the reverse rotation of the rotating disk, the center of the coin with the smallest diameter is the back surface of the back surface with respect to the rotational axis of the rotating disk. It is a coin dispensing device characterized in that it is located outside the reverse trajectory of the tip.

In the first invention, when the rotating disk rotates normally, the coin is guided by the circular peripheral surface of the outlet rotating body constituting the outlet guide in the process of being slid on the base by being pushed by the pushing front surface of the pushing body. Then, it is pushed in the circumferential direction of the rotating disk, pushed between the fixed body and the ejecting roller, and finally ejected by the ejecting roller.
When the rotating disk is reversed, the coin is pushed by the back surface of the pushing body and pressed against the ejecting roller and the exit rotating body. Therefore, the return force acting in the storage hole is exerted by the resultant force of the pressing force on the center of the coin and the reaction force from the outlet rotating body. In this case, since the outlet rotating body has a circular peripheral surface, the angle formed by the pressing force and the reaction force is larger than that when the outlet guide is a continuous arc-shaped or straight outlet guide. In other words, the resultant force acting as a return force is greater than that of a continuous arcuate or straight outlet guide. Furthermore, since the exit rotating body rotates, the coin and the circular circumferential surface are in rolling contact with each other, and the movement resistance of the coin is extremely small. As a result, even when the center of the coin is located outside the reverse trajectory of the back surface of the pusher, the coin can be returned into the storage hole. In other words, even when the center of the coin is located outside the reverse trajectory of the back surface of the pusher, the rotating disk can be reversed while rotating the coin, so that there is an advantage that the range of applicable coins can be expanded.
Furthermore, since the relationship between the coin and the outlet guide is a rolling contact, the payout resistance is reduced and the coin can be paid out smoothly.

In the second invention, when the rotating disk rotates normally, the coin is guided by the circular peripheral surface of the outlet rotating body constituting the outlet guide in the process of being slid on the base by being pushed by the pushing front surface of the pushing body. Then, it is pushed in the circumferential direction of the rotating disk, pushed between the fixed body and the ejecting roller, and finally ejected by the ejecting roller.
When the rotating disk is reversed, the coin is pushed by the back surface of the pushing body and pressed against the ejecting roller and the exit rotating body. Therefore, the return force acting in the storage hole is exerted by the resultant force of the pressing force on the center of the coin and the reaction force from the outlet rotating body. In this case, since the outlet rotating body has a circular circumferential surface, the angle formed by the pressing force and the reaction force is larger than that when the outlet guide is a continuous arcuate or straight outlet guide. In other words, the resultant force acting as a return force is greater than that of a continuous arcuate or straight outlet guide. Furthermore, since the exit rotating body rotates, the coin and the circular circumferential surface are in rolling contact with each other, and the movement resistance of the coin is extremely small. As a result, even when the center of the coin is located outside the reverse trajectory of the back surface of the pusher, the coin can be returned into the storage hole. In other words, even when the center of the coin is positioned outside the reverse trajectory of the back surface of the pusher, the rotating disk can be reversed while the coin is rotated, so there is an advantage that the range of applicable coins can be expanded.
Furthermore, since the relationship between the coin and the outlet guide is a rolling contact, the payout resistance is reduced and the coin can be paid out smoothly.
Further, since the outlet rotating body is a roller, there is an advantage that it can be manufactured at low cost by using a roller that is generally sold.

In the third invention, when the rotating disk rotates in the forward direction, the coin is guided by the circular peripheral surface of the outlet rotating body constituting the outlet guide in the process of being pushed by the pressing front surface of the pressing body and sliding on the base. Then, it is pushed in the circumferential direction of the rotating disk, pushed between the fixed body and the ejecting roller, and finally ejected by the ejecting roller.
When the rotating disk is reversed, the coin having the smallest diameter is pushed by the back surface of the pushing body and is pressed against the ejecting roller and the exit rotating body. Therefore, a return force acting toward the inside of the storage hole is exerted by the pressing force on the center of the coin with the smallest diameter and the resultant force of the reaction force from the outlet rotating body. In this case, since the outlet rotating body has a circular circumferential surface, the angle formed by the pressing force and the reaction force is larger than that when the outlet guide is a continuous arcuate or straight outlet guide. In other words, the resultant force acting as a return force is greater than that of a continuous arcuate or straight outlet guide. Furthermore, since the exit rotor rotates, the minimum diameter coin and the circular circumferential surface are in rolling contact, and the movement resistance of the minimum diameter coin is extremely small. As a result, even when the center of the minimum diameter coin is located outside the reverse trajectory of the back surface of the pusher, the minimum diameter coin can be returned into the storage hole. In other words, even when the center of the minimum diameter coin is located outside the reverse trajectory of the back surface of the pusher, the rotating disk can be reversed while rotating the minimum diameter coin, so that the range of applicable coins can be expanded. There is.
Furthermore, since the relationship between the coin and the outlet guide is a rolling contact, the payout resistance is reduced and the coin can be paid out smoothly.

  The best mode of the coin dispensing device according to the present invention is to drop a coin into a through hole formed at an eccentric position of a rotating disk rotating in a circular storage hole, and extend in the circumferential direction of the rotating disk below the rotating disk. An outlet extending in the circumferential direction of the rotary disk following the coin guide wall at the outlet while moving the coin on the base while guiding the coin to the coin guide wall of the storage hole while pushing the coin by the pushing front surface of the pusher After being pushed by the pushing front surface of the pushing body while being guided by a guide, the pushing body is ejected by a fixed body and a spring roller elastically biased so as to approach the stationary body, and when the rotating disk is reversed, the pushing body A coin dispensing device in which the coin is pushed by the back surface thereof and guided along the outlet guide and then returned to the storage hole. And the center of the minimum diameter coin is the rotation axis of the rotary disk when the minimum diameter coin comes into contact with the back surface, the ejection roller, and the roller at the time of reverse rotation of the rotary disk. On the other hand, the coin dispensing device is located outside the reverse trajectory of the back surface.

For convenience of explanation, except for the case of describing a coin of a specific denomination, the coin C is used as a generic name, and the minimum diameter coin SC is a 1-yen coin 1C, and therefore will be described as a “1-yen coin 1C”.

  As shown in FIG. 1, the coin dispensing device 100 has a function of separating 1-yen coins 1C to 500-yen coins 500C stacked one by one and then ejecting them one by one. , Frame 102, base 104, holding bowl 106, rotating disk 108, coin guide wall 110, restriction pin 112, outlet guide 114, fixed body 118 constituting the ejecting device 116 and flipping roller 120, coin detecting device 122, and A coin exit 123 is provided. The frame 102, the base 104, the holding bowl 106, the rotating disk 108, the coin guide wall 110, the regulation pin 112, the fixed body 118 constituting the ejecting device 116, the flip roller 120, the coin detecting device 122, and the coin outlet 123. Is a conventionally known structure, and the present invention relates to the structure of the outlet guide 114.

First, the frame 102 will be described mainly with reference to FIG.
The frame 102 has a function to which functional parts such as the base 104 and the storage bowl 106 are attached. In this embodiment, the frame 102 is made of sheet metal and has a hollow rectangular box shape.
The upper surface opening of the frame 102 is covered with a base 104.
A reverse gear is attached to the back surface of the base 104, and an electric motor 124 capable of rotating forward and backward is fixed. Its output shaft 126 protrudes above the base 104 through a circular through hole 128 formed in the base 104. Yes. When a coin jam occurs, the electric motor 124 is reversed for a predetermined time and a predetermined number of times, which contributes to the automatic release of the coin jam.
The base 104 is horizontally disposed in the present embodiment, but may be inclined.

Next, the base 104 will be described mainly with reference to FIG.
The base 104 has a function that the upper surface of the coin C is pushed and moved by the rotary disk 108, and is a flat plate made of stainless steel or wear-resistant resin, and the upper surface is formed with a predetermined flatness. Yes.
Further, a peripheral surface guide plate 130 having a predetermined thickness forming the coin guide wall 110 is closely fixed to the upper surface of the base 104.
Therefore, the base 104 can be replaced with another mechanism having a similar function.

Next, the storage bowl 106 will be described mainly with reference to FIG.
The holding bowl 106 has a function of holding a large number of coins C in a stacked state. In this embodiment, the holding bowl 106 is a resin-made generally vertical cylinder, and the inside of the cylinder extends in the vertical direction. The holding unit 132 is configured. The coin retaining part 132 is formed in a bottom hole 134 in which the horizontal section of the upper part 106A is rectangular and the horizontal section of the lower part 106U is circular, and the intermediate part 106M between the upper part 106A and the lower part 106U is inclined so that the coin C can slide down It is formed on the wall.
At the lower end of the storage bowl 106, a mounting portion 135 that protrudes in the lateral direction is formed in a bowl shape. By using this mounting portion 135, the storage bowl 106 is fixed to the base 104, specifically, the circumferential guide plate 130. .
Therefore, the storage bowl 106 can be changed to another device having a similar function.

Next, the rotating disk 108 will be described mainly with reference to FIGS.
The rotating disk 108 is rotated at a predetermined speed, stirs the coin C in the storage bowl 106, pushes the coin C that has fallen into the through-hole 136 formed at the eccentric position, and rotates the coin C. When a jam occurs, it has the function of reversing and eliminating the coin jam.
In this embodiment, the rotating disk 108 is disposed in the bottom hole 134 of the holding bowl 106 and is fixed in a counterclockwise direction in FIG. 2 when the coin C is dispensed by a DC electric motor 124 fixed to the back side of the base 104. When a coin jam occurs, it is rotated in the reverse clockwise direction at a predetermined speed.
The rotating disk 108 has a polygonal pyramid-shaped stirring portion 138 in the center, and agitates the coin C by rotating in the bottom hole 134 to help the coin C fall into the through hole 136.
The rotating disk 108 has a pusher 142 on the back surface of each rib 140 between the through holes 136.
The pusher 142 rotates and moves within the accommodation hole 144 of the circumferential guide plate 130 having a predetermined thickness that is closely fixed to the upper surface of the base 104, and the push front 147 rotates as shown in FIG. The disc 108 is curved so as to recede from the rotation axis RA side to the peripheral side toward the rear side in the rotation direction. More specifically, the pusher 142 is constituted by a first pusher 142A close to the rotation axis RA side and a second pusher 142B close to the peripheral side, and a first restricting pin 112A and a second restricting pin described later. An arcuate first relief groove 148A is formed on the rotation axis RA side of the first pusher 142A so that 112B can pass through, and a second escape groove 148B is formed between the first pusher 142A and the second pusher 142B. ing. The front surface of the first pusher 142A is the first push front surface 147A, and the front surface of the second pusher 142B is the second push front surface 147B.
Therefore, the coin C that has fallen into the through hole 136 is supported by being in surface contact with the base 104, and is pushed by the first pusher 142A by the rotation of the rotary disk 108 while being guided by the coin guide wall 110 of the storage hole 144. Then, the moving path MP is rotated along with the rotating disk 108. Next, when the coin C reaches a predetermined position in the outlet passage 152, the second pushing body 142B is pushed and pushed while being guided by the outlet guide 114 and the ejecting roller 120 and ejecting device 116. Move to.
On the other hand, the coin C that is moved by the rotating disk 108 without being guided by the coin guide wall 110 protrudes from the base 104, and the first restriction pin 112A and the second restriction pin 112A, which will be described later, are positioned in the movement path MP of the coin C. It is forcibly guided by the regulating pin 112B in the circumferential direction of the rotary disk 108, in other words, upward in FIG.
When a coin jam occurs, the rotating disk 108 is reversed. By this reverse rotation, the back end 150E of the back surface 150 of the second pusher 142B pushes the peripheral surface of the coin C and moves it in the direction opposite to that during forward rotation.

Next, the coin guide wall 110 will be described mainly with reference to FIGS.
The coin guide wall 110 has a function of guiding the peripheral surface of the coin C that is rotated by the rotating disk 108, and in this embodiment, is formed in a rectangular shape substantially the same as the base 104, and has a predetermined thickness, specifically Is the inner wall surface of the substantially circular storage hole 144 formed in the circumferential guide plate 130 having a thickness slightly larger than the thickness of the thickest coin C among the coins C to be handled. A storage hole outlet 154 is formed. In other words, the coin guide wall 110 is C-shaped, and the storage hole outlet 154 is formed about 1.5 times the diameter of the largest diameter coin. Specifically, the storage hole outlet 154 is a slit-shaped opening formed by the upstream end 110E and the downstream end 110L of the coin guide wall 110.
The peripheral surface guide plate 130 is tightly fixed to the upper surface of the base 104, and the lower surface of the attachment portion 135 of the storage bowl 106 is detachably fixed to the upper surface of the peripheral surface guide plate 130. In this state, the rotation axis RA and the axis of the bottom hole 134 and the storage hole 144 are arranged so as to coincide with each other. In other words, the axis in which the rotary disk 108, the bottom hole 134, and the storage hole 144 are suspended is the same. The diameter of the rotating disk 108 is slightly larger than the diameter of the storage hole 144, and the storage hole 144 is configured to be covered from above by the rotating disk 108. further. The peripheral end of the rotary disk 108 of the pusher 142 is formed to have a slightly smaller diameter than the storage hole 144 so as to rotate in the storage hole 144.
The coin C that has fallen into the through-hole 136 is guided by the coin guide wall 110 while being pushed by the pusher 142 in a state where the lower surface is supported by the base 104 as described above, and is moved through the movement path MP. . In other words, the movement path MP has a generally circular ring shape.
Therefore, the peripheral surface guide plate 130 only needs to have a function of guiding the coin C so that the coin C is guided by the coin guide wall 110 and moves along the movement path MP.
Note that the base 104 and the circumferential guide plate 130 can be formed integrally.

Next, the regulation pin 112 will be described mainly with reference to FIG.
The restricting pin 112 has a function to guide the coin C rotated by the rotating disk 108 to the circumferential direction of the rotating disk 108, in other words, to the storage hole outlet 154 side, and when the rotating disk 108 is reversed, The coin C is pushed downward by the coin C pushed by the back surface 150 of the moving body 142 and has a function of allowing the coin C to move in the reverse direction in the moving path MP. In this embodiment, the coin C elastically protrudes from the upper surface of the base 104. The first restriction pin 112A and the second restriction pin 112B are configured. However, the regulation pin 112 is not necessarily required when the coin C is directed toward the storage hole outlet 154 by centrifugal force, and can be installed as appropriate. In the present embodiment, the restriction pin 112 is arranged just in case.
The first restricting pin 112A and the second restricting pin 112B are cylindrical bodies that are erected and fixed to the other end of a leaf spring (not shown) whose one end is fixed to the back surface of the base 104, and the head of the cylindrical body. Protrudes from the through-hole formed in the base 104 onto the base 104, but protrudes to the extent that it does not hit the back surface of the rotating disk 108, and its head is moved by the coin C that is pushed in the reverse direction through the moving path MP. Inclined inclined surfaces 156 (first inclined surface 156A and second inclined surface 156B) are formed so that a component force pushed into the base 104 acts. For example, the invention disclosed in Utility Model Registration No. 2594435 is adopted as the shape of the head.
In the present embodiment, as shown in FIG. 10, the first extended line EA of the first inclined surface 156A and the second extended line EB of the second inclined surface 156B are formed so as to intersect at an obtuse angle Z. . When the coin C (one-yen coin 1C in the embodiment) is swung in the reverse direction by the back surface 150 of the pusher 142 when the rotary disk 108 is rotated in reverse, and is in contact with the second inclined surface 156B, the axis line with respect to the one-yen coin 1C As a result, the 1-yen coin 1C comes into contact with the first inclined surface 156A and the second inclined surface 156B, and then the first restriction pin 112A and the second one formed with them are applied. By continuously pushing down the regulation pin 112B, the rotating disk 108 is continuously reversed. When the bisector BIS of the obtuse angle Z intersects the straight line FL passing through the axis RA at a right angle, the center 1CC of the 1-yen coin 1C is located on the bisector BIS near the intersection. (It is the same for other denominations). By forming in this way, even when the coin C is in contact with the first inclined surface 156A or the second inclined surface 156B, the component C acting on the first inclined surface 156A or the second inclined surface 156B that is in contact with the coin C is used. Since both the first inclined surface 156A and the second inclined surface 156B are in contact with each other almost uniformly and a large force does not act on a part of the peripheral surface of the coin C, there is an advantage that the coin C is not damaged.
Therefore, when the coin C is pushed by the pusher 142 and collides with the first restricting pin 112A and the second restricting pin 112B during the normal rotation of the rotating disk 108, the coin C is pushed by the pusher 142 and the first restricting pin. Guided by 112A and the second restricting pin 112B and guided toward the storage hole outlet 154. When the rotating disk 108 is reversed, the coin C pushed by the back surface 150 of the pusher 142 is such that the first inclined surface 156A of the head of the first restriction pin 112A and the second restriction pin 112 and the second inclination. Since the surface 156B is pushed, a downward force acts on the first restriction pin 112A and the second restriction pin 112B and is moved into the base 104, so that the coin C is pushed by the back surface 150 of the pusher 142. The movement path MP is continuously moved in the direction opposite to the normal rotation direction.

Next, the outlet passage 152 will be described mainly with reference to FIG.
The outlet passage 152 is a passage through which the coin C moving from the storage hole outlet 154 can move to the coin outlet 123 described later, and is continuously formed downstream of the storage hole outlet 154. Therefore, the exit passage 152 does not need to be formed in a channel shape surrounded on three sides or a rectangular shape surrounded on all sides, and it is sufficient to guide at least the lower surface of the coin C. In this embodiment, the upper surface of the base 104 is used. Consists of.
Accordingly, the coin C that has moved from the storage hole outlet 154 is discharged from the coin outlet 123 described later through the outlet passage 152.

Next, the outlet guide 114 will be described mainly with reference to FIG.
The outlet guide 114 has a function of guiding the coin C toward the ejecting device 116 when the rotating disk 108 is rotated forward, and guiding the coin C back to the receiving hole 144 when the rotating disk 108 is reversed. A circular peripheral surface 160 positioned on the side of the upstream end 110E side of the hole outlet 154 is constituted by an outlet rotating body 162 that can rotate around the second axis RB. The outlet rotating body 162 uses a roller 164 in this embodiment, and more specifically, a small commercially available ball bearing. The roller 164 may be a roller bearing or a bush, but since a commercially available ball bearing is a mass-produced product, there is an advantage that the apparatus can be configured at low cost. When a ball bearing is used for the roller 164, the outer race corresponds to the roller 164, and the inner race is fixed to the first support shaft 158 or attached so as not to fall off.
In this embodiment, the roller 164 is rotatably mounted on the upper portion of the first support shaft 158 that is suspended from the base 104. Therefore, the outer peripheral surface of the roller 164 is a circular peripheral surface 160.
The outlet rotating body 162 is intermediate between the upstream end portion 110E of the coin guide wall 110 and the flipping roller 120, and is disposed on the side of the outlet passage 152, and is a flipping roller 120 positioned at a standby position SP described later. And a predetermined distance away from the first straight line L1 connecting the upstream end 110E. Specifically, the first peripheral line L1 and the circular peripheral surface 160 of the outlet rotator 162 are arranged at a distance of a half of the diameter of the outlet rotator 162 in the shortest distance. The position of the exit rotating body 162 is determined by the target minimum diameter coin, which is a 1-yen coin 1C in this embodiment, being pushed by the rotating disk 108, and hence the back end 150E of the pushing body 142, so that the standby position SP. The center 1CC of the 1-yen coin 1C is located outside the reverse trajectory CCL drawn by the back surface tip 150E when it is in contact with the flip roller 120 and the exit rotating body 162 (FIG. 11). The diameter of the outlet rotor 162 is comprehensively determined in consideration of the allowable dimensions of the apparatus, the applicable range of the diameter of the coin C, and the like, but the target from the 1-yen coin 1C to the 500-yen coin 500C in the present embodiment. In this case, 7 to 8 mm is preferable. Further, the position is preferably arranged at a position closer to the upstream end 110E than the intermediate point M between the upstream end 110E and the flip roller 120. The reason for this is that the coin C falls into the first gap 166 between the upstream end 110E and the outlet rotator 162 and the second gap 168 between the outlet rotator 162 and the flip roller 120. If it is large, coin jam may occur, and if it is small, the coin range on the small diameter side that can be paid out is limited. The drop amount of the 1-yen coin 1C in the first gap 166 is an allowable range of about one fifth of the radius of the 1-yen coin 1C. This is because if the 1-yen coin 1C falls more than this, the 1-yen coin 1C cannot move smoothly, and there is a possibility that a press mark may remain on the aluminum 1-yen coin 1C.

As shown in FIG. 5, when the rotating disk 108 rotates forward, the 1-yen coin 1C is pressed against the outlet rotating body 162 and the flip roller 120 by the second pusher 142B, and pushes from the second pusher 142B toward the coin center 1CC. The force F21 and the reaction force F22 directed from the flip roller 120 toward the coin center 1CC are pushed toward the fixed body 118, which will be described later, and pushed between the fixed body 118 and the flip roller 120 (FIG. 6). It is kicked out by the flip roller 120. The point of whether or not the 1-yen coin 1C is paid out at the time of forward rotation is that the 1-yen coin 1C is pushed by the outlet rotating body 162 from the pushing body 142 toward the coin center 1CC and the reaction force F22 from the flip roller 120. The resultant force F23 is directed toward the fixed body 118, and the resultant force F23 is set so as to be guided to a position where the resultant force F23 exceeds a resistance force such as the rotational resistance of the flip roller 120. By setting in this way, even a 1-yen coin 1C can be paid out smoothly without being damaged.
Further, when the rotating disk 108 rotates in the reverse direction, as shown in FIG. 11, a pressing force F11 directed toward the center 1CC of the 1-yen coin 1C from the pushing body 142, specifically, the back end 150E of the second pushing body 142B, and the exit rotating body The resultant force F13 with the reaction force F12 from the 162 toward the center 1CC of the 1-yen coin 1C is directed to the storage hole 144 side and is guided to a position exceeding the resistance force such as the rotational resistance of the outlet rotating body 162. Thus, the rotating disk 108 can rotate the 1-yen coin 1C in the reverse direction. With this setting, even if the coin center 1CC of the 1-yen coin 1C is located outside the reverse trajectory CCL of the back end 150E of the pusher 142, the 1-yen coin 1C can be returned into the storage hole 144. The rotating disk 108 can be continuously reversed, and the coin jam can be effectively eliminated.
As a result, since the coin center 1CC of the 1-yen coin 1C is positioned outside the reverse trajectory CCL, even a coin C having a smaller diameter can be rotated at the time of reversal, and there is an advantage that the applicable range of the coin diameter is widened.

Next, the ejecting device 116 will be described mainly with reference to FIGS.
The ejecting device 116 has a function of ejecting the coin C pushed in the circumferential direction of the rotary disk 108 by the second pushing front surface 147B of the pushing body 142 by the resilient force of the elastic body, and is fixed in this embodiment. A body 118 and a flip roller 120 are included.

First, the fixed body 118 will be described.
The fixed body 118 receives the coin C pushed by the pushing body 142 and pushed out to the storage hole outlet 154, and guides it in the circumferential direction of the rotating disk 108, in other words, defines one side of the outlet passage 152. It has a function, and is constituted by a fixed roller 170 and a fixed guide 171 in this embodiment.
The fixing roller 170 is not completely fixed, and is preferably set so as to be able to move slightly and buffer the excessive force when an excessive force is applied as described later. This is to improve the durability of the device. The fixed roller 170 does not need to be a roller, and may be a plate formed integrally with the fixed guide 171. For example, a part of the peripheral surface guide plate 130 may be an arc-shaped peripheral surface corresponding to the fixed roller 170, and the fixed guide 171 may be formed subsequently. Therefore, the fixed body 118 can be changed to another device having the same function.
In this embodiment, the fixed roller 170 protrudes upward from a first lever 174 that is instructed to rotate freely by a second support shaft 172 that protrudes downward on the back surface side of the base 104, and has a through-hole ( The roller 178 is a ball bearing 178 that is rotatably supported at the tip of a third support shaft 176 that passes through (not shown) and is located on the upper surface side of the base 104. The first lever 174 is urged in the clockwise direction in FIGS. 2 and 4 by the elastic force of the elastic body, in this embodiment, the first spring 180, to the position in FIG. 2, that is, the downstream end 110L of the storage hole 144. At a position adjacent to the first lever 174, the first lever 174 is locked by the first stopper 182 and kept stationary.
In this stationary position, the inner peripheral surface of the ball bearing 178 is disposed on the virtual circle of the storage hole 144 so that the peripheral surface of the ball bearing 178 forms a part of the inner surface of the storage hole 144.
The first spring 180 is not normally moved when the coin C collides, but when a force larger than usual is applied, its resilient force is set so as to slightly move away. This is because even a slight escape movement can buffer the overload caused by the coin C, which contributes to the improvement of the durability of the apparatus.

Next, the fixed guide 171 will be described.
The fixed guide 171 has a function of guiding the coin C guided by the fixed roller 170 in a predetermined direction, and a function of finally ejecting the coin C with the flip roller 120. A first straight portion 184, a curved portion 186, and a second straight portion 188 are formed in this order from the fixed roller 170 side.
The first straight portion 184 has an extension line EL that is tangent to the fixed roller 170, and further extends from the end of the coin guide wall 110, so that the tangent line CL to the fixed roller 170 forms an acute angle close to 90 degrees. Is formed.
The second straight portion 188 is formed in parallel with a perpendicular line VL (referred to as a perpendicular line for convenience) passing through the rotation axis RA in FIG.
The curved portion 186 is formed in an arc that smoothly connects the first straight portion 184 and the second straight portion 188.
The second straight line portion 188 that determines the final payout direction of the coin C is appropriately determined according to the payout direction of the coin C, and may not be parallel to the perpendicular line VL or may be a curved line.
In this embodiment, the fixed guide 171 is configured separately from the base 104 and the peripheral surface guide plate 130, but can be configured integrally with one or both of them.

Next, the flip roller 120 will be described mainly with reference to FIG.
The flip roller 120 is pushed by the exit passage 152 and has a function of flipping out coins C guided partially or entirely by the fixed guide 171. In the present embodiment, the flip roller 120 protrudes downward from the back surface of the base 104. Fixed upward from the end of the second lever 192, a part of which is rotatably supported by the support shaft 190, and penetrating through an arc-shaped slot 194 formed in the base 104 in an arc shape around the fourth support shaft 190. The roller is rotatably attached to the upper end portion of the fifth support shaft 196 projecting upward from the base 104, and is a ball bearing 197 in this embodiment.
Therefore, the flip roller 120 can be changed to another device having a similar function.
The second lever 192 is formed by a second spring 202 having an end locked to a first locking portion 198 formed at a part thereof and a second locking portion 200 protruding downward from the base 104.
Due to the second stopper 204 that is elastically biased toward the fixed body 118 and protrudes downward from the back surface of the base 104, the linear distance L between the fixed body 118 and the flip roller 120 is set to It is locked to rest at a position slightly smaller than the minimum diameter. More specifically, the shortest distance L between the fixed roller 170 and the flip roller 120 forms an entry gap 206 that is slightly smaller than the diameter of the 1-yen coin 1C.
Accordingly, the center 1CC of the 1-yen coin 1C pushed by the pusher 142 connects the contact PA between the fixed roller 170 and the 1-yen coin 1C and the contact PB between the flip roller 120 and the peripheral surface of the 1-yen coin 1C. Immediately after crossing the straight line DL, the flipping roller 120 starts to be ejected by the resilient force of the second spring 202, and finally the 1-yen coin 1C straddles between the first linear portion 184 and the fixed roller 170. In the supported state, it is ejected by the flip roller 120 in a direction parallel to the first straight portion 184. The flipped coin C is gently changed in direction by the bending portion 186, and then linearly guided by the second straight portion 188, and is released in a direction parallel to the perpendicular VL.

  In addition, the 1-yen coin 1C is guided to the exit rotary body 162 by the normal rotation of the rotary disk 108, and is pushed by the pushing force F21 by the second pushing body 142B, and by the reaction force F22 from the flip roller 120. By the resultant force F23, the 1-yen coin 1C is guided to the fixed body 118 side, and a part of the 1-yen coin 1C advances to the entry gap 206. When the rotating disk 108 further rotates forward, the coin C is pushed into the entry gap 206 by the pushing force of the second pusher 142B (FIG. 6), so the flip roller 120 is fixed against the spring force of the second spring 202. It is moved away from the roller 170. More specifically, when the entrance gap 206 is widened and the center 1CC of the 1-yen coin 1C passes through the straight line DL connecting the contact PA and the contact PB (FIG. 7), the ejecting force by the second spring 202 is 1 yen. Since it acts on the coin 1C, it starts to be ejected, and finally it is ejected by the ejecting roller 120 immediately after part of the end 182E of the first linear portion 184 and the fixed roller 170 come into contact with each other. The ejected coin C is paid out in a direction parallel to the perpendicular line VL while being guided by the fixed guide 171. In the middle of the payout, the coin C is detected by the coin detection device 122.

Next, the coin detection device 122 will be described.
The coin detecting device 122 has a function of detecting the coin C ejected by the ejecting device 116, and in this embodiment, a magnetic metal sensor 208 is used. Therefore, the coin detection device 122 can be changed to another device having the same function, for example, a photoelectric sensor, a mechanical sensor, or the like.
In the present embodiment, the coin detection device 122 is disposed relative to the outlet passage 152 on the side of the second linear portion 188, but can be disposed downstream of the coin outlet 123.

Finally, the coin outlet 123 will be described with reference to FIG.
The coin outlet 123 has a function of delivering the coin C from the base 104, and is not particularly required to be configured as a slit-shaped passage or the like, and is configured at the downstream end of the outlet passage 152 in this embodiment. In other words, the end of the base 104 facing the outlet passage 152 is the coin outlet 123.

Next, the operation of the coin dispensing apparatus 100 will be described with reference to FIGS.
When paying out coins with a diameter in a predetermined range with one device without changing parts or adjusting the position, the smallest diameter coin SC is the most problematic, so a 1-yen coin 1C will be described as an example.
Further, since the operation is different between the case where the coin 1C moves along the coin guide wall 110 of the storage hole 144 and the case where the coin C is guided and paid out by the regulation pin 112, each case will be described separately.

First, a case where the 1-yen coin 1C moves along the coin guide wall 110 will be described.
The coin C in the storage bowl 106 falls into the through hole 136 by the rotation of the rotary disk 108, and the front or back surface thereof is supported by being in surface contact with the base 104, and is pushed by the first pusher 142A. At the same time, it is moved to the storage hole outlet 154 side while being guided by the coin guide wall 110 as the peripheral wall of the storage hole 144 (FIG. 3).
The coin C that has reached the storage hole outlet 154 falls into the first gap 166 from the upstream end 110E and is supported by the circular circumferential surface 160 of the outlet rotating body 162 to prevent further depression, and then the circular circumferential surface. After being guided by 160 and slightly moving toward the entry gap 206, it falls into the second gap 168, and then comes into contact with and guides the flip roller 120 located at the standby position SP (FIG. 5).
When the 1-yen coin 1C comes into contact with the second pushing front surface 147B, the circular circumferential surface 160 and the flip roller 120 of the second pushing body 142B, as described above, the center of the coin of the 1-yen coin 1C from the second pushing front surface 147B. Since the resultant force F23 of the pressing force F21 toward 1CC and the reaction force F22 from the flip roller 120 is directed to the fixed roller 170 side, the 1-yen coin 1C is guided to the arcuate peripheral surface of the flip roller 120 toward the entry gap 206 side. It moves toward and is located in the entrance gap 206 (FIGS. 5 and 6).
With the further rotation of the rotating disk 108, the 1-yen coin 1C is pushed into the entry gap 206 by the second pushing front surface 147B, and is thus moved in the circumferential direction of the rotating disk 108 along the arcuate circumferential surface of the fixed roller 170. Therefore, the flip roller 120 is rotated clockwise in FIG. 2, and the entry gap 206 is further expanded.
The 1-yen coin 1C is further moved in the circumferential direction of the rotating disk 108, and a straight line connecting the contact point PA between the circumferential surface and the fixed roller 170 and the setting roller PB of the flip roller 120 and the circumferential surface of the 1-yen coin 1C. Immediately after the center 1CC of the 1-yen coin 1C passes through L, it receives a repelling force from the repelling roller 120 (FIG. 7).
Next, in a state where the circumferential surface of the 1-yen coin 1C is in contact with the end 182E of the first linear portion 184 and the fixed roller 170, the flip roller 120 pushes the circumferential surface of the 1-yen coin 1C by the spring force of the spring 202. Then, it flips out toward the curved portion 186 (FIG. 8).
The flipped 1-yen coin 1C is guided by the curved portion 186, and then is guided by the second straight portion 188 and jumps out from the coin outlet 123 in a direction parallel to the perpendicular VL (FIG. 9).

Next, a case where the 1-yen coin 1C is guided by the regulation pins 112A and 112B and pushed into the entry gap 206 without being guided by the coin guide wall 110 will be described.
In this case, the 1-yen coin 1C does not come into contact with the exit rotating body 162, but travels in the entry gap 206 and then flips in a state of being in contact with the tip 182E of the first straight portion 184 and the fixed roller 170 as described above. Played by the roller 120.

Next, a case where the rotating disk 108 is reversed to eliminate coin jam will be described.
In this case, there is a problem in that the normal rotation of the rotating disk 108 stops at the phase where the 1-yen coin 1C is pushed into the entry gap 206, and this situation will be described as a starting point.
When the rotary disk 108 starts reverse rotation, the second pusher 142B rotates clockwise in FIG. 10, and the 1-yen coin 1C is not pushed by the second push front face 147B. The flip roller 120 is rotated counterclockwise by the force and returns to the standby position SP (FIG. 10). As a result, the 1-yen coin 1C is returned to the storage hole 144 side, and temporarily stops at a position corresponding to the standby position SP of the flip roller 120.
By further reverse rotation of the rotating disk 108, the 1-yen coin 1C is pushed rightward in FIG. 10 by the back end 150E of the second pusher 142B. At this time, the back end 150E contacts at one point on the peripheral surface of the 1-yen coin 1C and is pushed by the pressing force F41, and the reaction force F41 is generated from the flip roller 120. Therefore, the resultant force F43 is 1-yen coin 1C. Therefore, the 1-yen coin 1C is laterally pushed and pushed toward the storage hole 144, in other words, pushed toward the second gap 168.
Then, as shown in FIG. 11, when the 1-yen coin 1C comes into contact with the ejecting roller 120 and the outlet rotating body 162, the pressing force F11 by the back end 150E is applied to the repelling roller 120 by the fourth support shaft 190 and the fifth Since it acts from a lateral direction substantially perpendicular to the straight line FL connecting the support shaft 196, the ejecting roller 120 remains stationary.
From the exit rotor 162, a reaction force F12 equivalent to the pressing force F11 acts on the coin center 1CC of the 1-yen coin 1C. Since the resultant force F13 of the pressing force F11 and the reaction force F12 is directed to the storage hole 144, the 1-yen coin 1C is guided to the peripheral surface of the outlet rotating body 162 by the further reverse rotation of the rotating disk 108, and the first gap portion 166. Is reached, is guided by the upstream end portion 110E, is returned into the storage hole 144, and is moved along the coin guide wall 110.
Note that the coin C positioned downstream of the first restriction pin 112A and the second restriction pin 112B is the first inclined face 156A and the second inclined face 156B at the tips of the first restricting pin 112A and the second restricting pin 112B. , The rotary disk 108 is continuously rotated. Therefore, the rotating disk 108 can be reversed at an angle sufficient to eliminate the coin jam, and the coin jam can be eliminated.
