Coin dispenser

The present invention relates to coin dispensing apparatus for feeding the coins to be pending bulk state one by one to the next step.
In particular, the present invention relates to a coin dispensing device that sends out coins made of a relatively soft material to the next process one by one without producing a compression mark.
Furthermore, the present invention relates to a coin dispensing device that does not cause pressure marks on coins and that can reduce energy consumption by reducing resistance during ejection.
The “coin” used in this specification includes Japanese coins, US coins, euro coins, and all other coins, and tokens and medals that are used in a similar manner to coins. Further, the normal rotation of the rotating disk refers to rotation in a direction in which coins can be sent out by rotating the rotating disk.

As a prior art, in a coin hopper having a coin holding bowl and a rotating disk having a first pushing portion and a second pushing portion that are located at the bottom of the holding bowl and push a coin, according to the application of the present applicant, A rotating disk of a coin hopper whose first pushing portion is a pushing roller is known (Patent Document 1).
In detail, the coin is placed in a circular bottom hole of a coin holding container that holds the coins in a loose state, and the outer periphery is positioned on the peripheral edge through a through hole through which the coin can pass from the upper side to the lower side. The coin that has been dropped onto the base through the through-hole by the rotation of a rotating disk having a coin pushing portion comprising a moving portion and an inner pushing portion located on the axial center side, or the inner pushing portion or The guide is arranged in a fixed state with respect to the base after sliding on the base while being pushed along the guide circular hole arranged outside the outer pushing portion by being pushed by the outer pushing portion. 2. Description of the Related Art There is known a coin dispensing device that is adapted to be ejected by a body and a repelling roller that is elastically biased so as to approach the guide body.

Japanese Patent No. 4784805 (paragraph numbers 0006 to 0009, FIGS. 2 to 5)

In the prior art, the outer pushing portion formed on the lower surface of the rotating disk is positioned rearward with respect to the inner pushing portion in the forward rotation direction of the rotating disk. Gives a pressing force against the peripheral surface. In other words, since the coin is pressed against the inner peripheral surface of the guide circular hole, a coin made of a soft material, such as a Japanese one-yen coin, is pressed toward the center from the peripheral surface side, so that the peripheral portion is plastic. Deformation increases the thickness of the peripheral edge, and there is a risk that the automatic processing machine for coins cannot be processed or misidentified.
This problem will be described with reference to a conventional coin dispensing apparatus 10 shown in FIG.

The rotary disk 12 is rotatably disposed in a circular bottom hole 16 of a vertically-oriented cylindrical coin storage container 14 for a 1-yen coin 1C. The rotating disk 12 is rotated counterclockwise at a predetermined speed around the axis SC of the rotating shaft 18, and through holes 20A to 20E having a predetermined diameter are formed at equal intervals on the periphery, and the through holes 20A to 20E are formed. In between, ginkgo leaf-shaped ribs 22A to 22E that expand toward the peripheral side of the rotary disk 12 are formed, and the lower surface of the ribs 22A to 22E pushes the coin C, so that it has a predetermined size downward. Protruding pushers 24A to 24E are formed. The pushing portions 24A to 24E are rotatably arranged in a circular guide hole 28 formed on the upper surface of the flat base 26, and the lower surface thereof has a distance of half or less of the thinnest coin with respect to the base 26. It is rotated. Since the pushing portions 24A to 24E have the same configuration, the pushing portion 24A will be described as a representative. The pushing portion 24A is composed of an inner pushing portion 24i located on the axis SC side and an outer pushing portion 24E located on the peripheral edge side. The outer pushing portion 24E is the inner side in the forward rotation direction of the rotary disk 12. It arrange | positions so that it may be located behind the pushing part 24i. The inner pushing portion 24i is formed integrally with the rotary disk 12 and has a trapezoidal shape when viewed from the back side, and the pushing surface 30 located on the front surface comes into contact with the peripheral surface of the coin C and pushes. The push surface 30 is formed in an arc shape that curves forward in the traveling direction, and the rear surface extends downward from the peripheral surface of the through hole 20B for a predetermined length. The outer pushing portion 24E is constituted by a small-diameter roller 34 that is rotatably supported by a shaft 32 that protrudes downward from the back surface of the rotating disk 12. Accordingly, an arc-shaped outer escape groove 36E is formed between the roller 34 and the inner pushing portion 24i. The gap regulating body 38 located in the central portion surrounding the rotation shaft 18 has a petal shape, and an arc-shaped inner escape groove 36i having a rectangular cross section is formed between the gap regulating body 38 and the inner pushing portion 24i. A part of the peripheral wall of the guide hole 28 is cut off to form an opening 40. A guide roller 42 substantially fixed to the base 26 is disposed on one side of the opening 40, and the guide roller 42 is disposed on the other side. A repelling roller 44 that is elastically biased so as to approach is located. A standard body projecting from the base 26 close to the opening 40 to the moving passage 46 by an amount smaller than the thickness of the 1-yen coin 1C , in this example, a pair of internal standard bodies 48i and an external standard body 48E project.

Next, the operation of this prior art will be described.
The 1-yen coin 1C that has fallen into the through holes 20A to 20E slides on the base 26 while being pushed by the pushing portions 24A to 24E, and the periphery is guided by the inner peripheral surface 50 of the circular guide hole 28 by the rotating disk 12. The moving passage 46 is taken along. The 1-yen coin 1C to be rotated is guided to the opening 40 by being guided in the circumferential direction of the rotary disk 12 and therefore the guide hole 28 by the inner setting body 48i and the outer setting body 48E protruding from the base 26 to the moving passage 46. When the center CC of the coin C is pushed between the guide roller 42 and the flip roller 44 and exceeds the contact point between the coin C and the guide roller 42 and the straight line connecting the contact point with the flip roller 44, the flip roller Bounced by the elasticity of 44.

Therefore, the coin C is normally pushed along the moving passage 46 by the rotating disk 12 while being pushed by the inner pushing portion 24i and guided to the inner peripheral surface 50 of the guide hole 28.
During this rotation, the contact point P1 between the 1-yen coin 1C and the inner pushing portion 24i is closer to the axial center SC than the center CC of the coin C, so the pressing force F from the contact P1 to the center CC of the coin C is F Acts and the peripheral surface is rotated while being pressed against the inner peripheral surface 50 of the guide hole 28 by the component force. The virtual circle IC is a virtual circle centered on the axis SC and having a radius from the axis SC to the contact point P1. As a result, the 1-yen coin 1C is pressed against the inner peripheral surface 50 of the guide hole 28 by the component force, so that the 1-yen coin 1C made of a soft material is compressed by the component force, and is plastically deformed as a result. The thickness of the part may increase. When the 1-yen coin 1C is plastically deformed, it deviates from the normal thickness, which may cause problems in processing in various coin processing machines. For example, in the case of 1-yen coin 1C in Japan, there is a concern that a coin clogging may occur in the 1-yen coin 1C alignment processing device, or it may be identified as a fake coin even though it is a genuine coin.
Further, since the 1-yen coin 1C and the inner peripheral surface 50 of the guide hole 28 or the inner pushing portion 24i are a slip pair, the coin C is between the inner peripheral surface 50 or the inner pushing portion 24i. There was a risk that the peripheral surface could be damaged by the slippage.

The seventh invention is configured as follows.
An outer pushing portion and a shaft that are arranged in a circular bottom hole of a coin holding container for holding coins in a stacked state , and through which the coin can pass from the upper side to the lower side in the peripheral portion, and an outer pushing portion and a shaft that are positioned on the peripheral side on the lower surface The coins dropped onto the base through the through-holes by the rotation of a rotating disk having a coin pushing portion including an inner pushing portion located on the center side, the inner pushing portion or the outer pushing force. The guide body is arranged in a substantially fixed state with respect to the base after being slid along the guide circular hole arranged outside the outer pushing portion by being pushed by the portion. And a coin dispenser that is elastically biased so as to approach the guide body, wherein the inner pushing portion is behind the outer pushing portion in the forward rotation direction of the rotary disk. When placed , A plane facing the circumferential direction of the rotating disk, the outer pressing portion is a roller, and the peripheral surface of the coin is in contact with the inner peripheral surface of the guide circular hole and the roller constituting the outer pressing portion. In this state, the contact point between the outer pressing portion and the peripheral surface of the coin is disposed farther from the axis of the rotating disk than the center of the coin, and further away from the axis sequentially with respect to the roller. And an extruding portion extending rearward in the forward rotation direction of the rotating disk is disposed, and a rear end of the extruding portion in the forward rotation direction is located behind a rear end of the inner pushing portion. The coin dispensing device is located farther from the axis than the rotating roller.

In the first invention, the pushing portion formed on the lower surface of the rotating disk and pushing the coin includes an outer pushing portion located on the peripheral side and an inner pushing portion located on the axial center side. The moving portion is arranged behind the outer pushing portion in the forward rotation direction of the rotary disk, and the rotation is performed in a state where the circumferential surface of the coin is in contact with the inner circumferential surface of the guide circular hole and the outer pushing portion. Since the contact point between the outer pushing portion and the peripheral surface of the coin is located farther from the center of the coin with respect to the axial center of the disc, and the inner pushing body does not contact the coin, On the other hand, a force that pushes from the outer pushing portion toward the axial center of the rotating disk acts. In other words, since the coin receives a force in a direction away from the inner peripheral surface of the guide circular hole, the coin peripheral surface is rotated by the rotating disk while receiving a force separating the inner peripheral surface. Therefore, even if the coin floats from the inner peripheral surface, or even when the peripheral surface of the coin is not separated from the inner peripheral surface, the coin is swung around with a low contact pressure on the inner peripheral surface. There is no plastic deformation. Therefore, there is an advantage that the first object which is the basic object of the present invention can be achieved.

In the second invention, since the main configuration is substantially the same as that of the first invention, there is an advantage that the first object which is the basic object of the present invention can be achieved like the first invention.
Further, in the second invention, since the outer pushing portion is constituted by a roller, the contact between the coin peripheral surface and the outer pushing portion becomes a rolling contact, and it becomes a rolling pair with the coin. Since it is not damaged as much as possible, there is an advantage that the second object which is a subordinate object of the present invention can be achieved.

In the third invention, since the main configuration is substantially the same as that of the second invention, the first object which is the basic object of the present invention and the second object following the same are achieved as in the second invention. There are advantages you can do.
Further, in the third aspect of the invention, there is disposed an extruding portion that sequentially moves away from the axis of the rotating disk with respect to the roller that constitutes the outer pushing portion, and that extends to the rear side in the forward rotation direction of the rotating disk. Therefore, since the push-out part is responsible for the function of pushing the coin between the fixed guide body and the flipping roller, the structure of the roller constituting the outer pushing part can be made relatively low in strength, so that the coin dispensing There is an advantage that the device can be manufactured at low cost and the third object of the present invention can be achieved.

In the fourth invention, since the main configuration is substantially the same as that of the first invention, there is an advantage that the first object which is the basic object of the present invention can be achieved as in the first invention.
Further, since the inner pushing portion is disposed behind the outer pushing portion in the forward rotation direction of the rotating disk and is a plane facing the circumferential direction of the rotating disk, the coin is pushed by the inner pushing portion. In the case of being performed, a force toward the peripheral side of the rotating disk is applied to the center of the coin. Accordingly, since the coin receives a force from the inner pushing portion toward the peripheral side of the rotating disk and a centrifugal force acts on the coin, the coin moves to the peripheral side of the guide circular hole, contacts the inner peripheral surface and is moved by the outer pushing portion. Since it is pushed, it is rotated with the rotating disk while receiving a force toward the axial center of the rotating disk.
Accordingly, since the coin is rotated while receiving the force toward the axial center of the rotating disk while being in contact with the inner peripheral surface of the guide circular hole, in most cases, the guide body and the flip roller are not guided by the setting body. Since it is pushed in between, there is an advantage that the first object, which is the basic object of the present invention, can be further achieved without damaging the coins and without being damaged. Furthermore, since the inner pushing portion is a flat surface, it rolls against the movement with the coin and becomes an even number. Therefore, there is an advantage that the second purpose which is a secondary purpose can be achieved without damaging the coin.

In the fifth invention, since the main configuration is substantially the same as that of the third invention, the first object, the second object, and the third object, which are the basic objects of the present invention, can be achieved in the same manner as the third invention. There are advantages.
Further, since the inner pushing portion is disposed behind the outer pushing portion in the forward rotation direction of the rotating disk and is a plane facing the circumferential direction of the rotating disk, the rotation of the rotating disk with respect to the center of the coin. Gives the force toward the edge. Therefore, the coin receives a force toward the axial center of the rotating disk from the outer pushing part, receives a force toward the peripheral side of the rotating disk from the inner pushing part, and the inner peripheral surface by the outward force and centrifugal force. It is swung around with the rotating disk in contact with the disk.
Therefore, since the coin is rotated while receiving the force from the outer pushing portion toward the axial center of the rotating disk while being in contact with the inner peripheral surface of the guide circular hole, the compression force of the coin is weakened, so that a compression mark may be attached. There is an advantage that the first object which is the basic object of the present invention can be further achieved. Furthermore, since the inner pushing portion is a flat surface, it rolls against the movement with the coin and becomes an even number, so that there is an advantage that the second purpose, which is a secondary purpose, can be achieved without damaging the coin.

In the sixth invention, the main structure is substantially the same as that of the fifth invention, so that the first, second, and third objects, which are the basic objects of the present invention, can be achieved as in the fifth invention. There are advantages.
Further, since the roller constituting the outer pushing portion is sequentially moved away from the axis of the rotating disk and has an extruding portion extending to the rear side in the normal rotation direction of the rotating disk, the coin is fixed in the guide body. Since the push-out portion assumes the function of pushing between the roller and the flipping roller, the structure of the roller constituting the outer pushing portion can be made relatively low in strength, and the coin dispensing device can be manufactured at low cost. There is an advantage that the third object of the present invention can be achieved.

In the seventh invention, the main structure is substantially the same as that of the sixth invention, so that the first object, the second object and the third object which are the basic objects of the present invention are the same as the first invention. There are benefits that can be achieved.
Furthermore, since the rear end of the pushing part in the forward rotation direction is located behind the rear end of the inner pushing part and is located farther from the axis of the rotating disk than the rotating roller, the rotating disk is reversed. In this case, the range in which the coins sent out by the outer pushing portion can be returned into the guide hole is increased, so that when the coin is jammed, there is an advantage that the jam can be eliminated.

The axis CS of the guide circular hole 118 and the axis of the bottom hole 117 of the coin storage container 102 are the same.

Next, the rotating disk 110 will be described mainly with reference to FIGS.
The rotating disk 110 has a function of sorting the coins C one by one and then rotating them together with the rotating disk 110 and further pushing them in the circumferential direction of the rotating disk 110. In the first embodiment, at least the disk A circular disk main body 124, a through hole 126 formed in the eccentric part of the disk main body 124, and a pushing part 128 formed on the back surface.

First, the disk main body 124 will be described.
The disk main body 124 is formed by integral molding of metal or wear-resistant resin or the like, and is fixed to the tip of the rotary shaft 130 that is suspended from the base 106, so that at least the upper part in the thickness direction is a coin retaining portion. The pusher 128 disposed at the bottom hole 117 of the container 102 and rotated at the lower end is rotated at a predetermined speed in the guide circular hole 118. Therefore, the axes of the rotating shaft 130 and the rotating disk 110 also coincide with the axis CS. Further, the inner peripheral surface 120 is located outside the pushing portion 128. Since the rotary shaft 130 is suspended from the base 106, the rotary disk 110 is also tilted forward and rotated in a plane parallel to the base 106. In other words, the base 106 and the rotating disk 110 are arranged in parallel at a predetermined distance D1. The interval D1 is the interval between the back surface 124R of the rotating disk 110 (disk main body 124) and the upper surface of the base 106. The lower end of the pushing portion 128 and the base 106 are not in contact with each other, and the thickest coin expected to be used is When sliding on the base 106, a slight gap is formed between the upper surface and the rear surface 124R of the coin.
Around the rotating shaft 130 on the upper surface side of the disk main body 124, a polygonal pyramid-shaped stirring portion 132 is formed, and the coins C stacked in the coin holding container 102 are stirred when the rotating disk 110 rotates.
A gap restricting portion 134 that protrudes downward in a cylindrical shape is formed around the rotating shaft 130 on the back surface 124R side of the disc body 124, and the lower end of the pushing portion 128 is half the thickness of the thinnest coin with respect to the base 106. It regulates to rotate at the following intervals. In addition, a sheet 136 made of a low friction body can be interposed between the lower end surface of the gap regulating portion 134 and the base 106 to reduce frictional resistance.

Next, the through hole 126 will be described.
In the first embodiment, since six through-holes 126 are formed, for convenience, the numerals 126 are displayed with alphabets A to F, and when individually described, combinations of numerals and alphabets are used. If the individual explanation is unnecessary, only the numeral 126 is used as a generic name, and the same applies to the explanation of other configurations.
The through-hole 126 has a function of stirring the coins C stacked in the coin storage container 102 and dropping them one by one into the through-hole 126, and thereby sorting the coins C one by one. 1, there are six circular through holes 126 </ b> A to 126 </ b> F formed at equal intervals at eccentric positions of the disk main body 124. The diameter of the through holes 126A to 126F may be set to a diameter that allows the coin of the maximum diameter of the target denomination to fall smoothly so as to be capable of dealing with two or more denominations, as in the first embodiment. It is also possible to use a dedicated diameter for the coin C to fall most smoothly and be processed. For example, since the diameter of a 1-yen coin is 20 mm, it is formed to 21.5 mm including 1.5 mm.
When formed in this way, the edge on the rotating shaft 130 side of the through holes 126A to 126F bites into the gap regulating part 134, so that the gap regulating part 134 has a petal shape.
Between the adjacent through holes 126A to 126F, fan-shaped ribs 138 (138A to 138F) that expand toward the periphery are formed.

Next, the pushing portion 128 will be described.
The pushing portion 128 is a ring-shaped coin passage 140 formed between the gap regulating portion 134 and the guide circular hole 118 so that the coin C dropped into the through holes 126A to 126F by the rotation of the rotating disk 110 (FIG. 2). The first embodiment includes a plurality of pushing portions 128A to 128F formed on the lower surfaces of the ribs 138A to 138F. The pushing portions 128A to 128F are protrusions that protrude downward, and the structures of the pushing portions 128A to 128F are all the same, and therefore, the pushing portion 128A will be described as a representative.

The pusher 128A is composed of at least two of an outer pusher 128e and an inner pusher 128i. In other words, the pusher 128A can form an intermediate pusher between the outer pusher 128e and the inner pusher 128i. In this case, the intermediate pusher may be the inner pusher 128i for the outer pusher 128e, and the intermediate pusher may be the outer pusher 128e for the inner pusher 128i. There is.
First, the outer pushing portion 128e will be described.
When the coin C is guided to the inner peripheral surface 120 of the guide circular hole 118, when the outer pressing portion 128e is guided to the inner setting body 112i and the outer setting body 112e, and when being guided by the guide body 114, , Has a function of pushing the coin C.
In the first embodiment, the outer pushing portion 128e is configured by a roller 144A disposed on the lower surface of the rib 138A at a position close to the periphery of the disk main body 124.
The roller 144A is rotatably attached to a fixed shaft 146D that protrudes downward from the disc body 124 in the vicinity of the periphery of the disc body 124. In the first embodiment, the roller 144A is configured such that a bottomed cylindrical roller body 147R is rotatably mounted on a bearing 147B in which a flange 147F is formed at a lower end portion of a screw 145A that passes through the disk main body 124 from the upper side to the lower side. It is comprised by. Therefore, in the first embodiment, the screw 145A is the fixed shaft 146A. However, a commercially available ball bearing can be used instead of the roller body 147R. This is for easy availability and cost reduction.
The outer peripheral surface 148A is a circumferential surface on the front side in the forward rotation direction of the rotating disk 110 of the roller 144A. The diameter of the roller 144A is suitably one fifth to one sixth of the diameter of the largest coin that is expected to be used. The forward rotation direction of the rotating disk 110 refers to the rotating direction of the rotating disk 110 from which the coin C can be paid out.

Next, the inner pushing portion 128i will be described.
The inner pushing portion 128i is a protrusion that protrudes downward from the lower surface of the rib 138A. In the first embodiment, the inner pushing portion 128i has a trapezoidal shape when viewed from the rear side, and the front side in the forward rotation direction of the rotating disk 110 constitutes the inner front surface 154A. The rear side in the rotation direction constitutes the inner rear end 156A. Therefore, an arc-shaped outer relief groove 158A centering on the axis CS of the rotary disk 110 is formed between the roller 144A and the inner pushing portion 128i so that the outer regulator 122e can pass therethrough.
The inner rear end 156A of the inner pushing portion 128i in the forward rotation direction of the rotating disk 110 is preferably formed flush with the periphery of the through hole 126B. This is because the amount of movement of the coin C that has fallen into the through-hole 126B is suppressed as much as possible to prevent the coin C from being ramped up and as a result to prevent unexpected troubles.
Further, the inner front surface 154A is formed so as to be positioned on the rear side in the forward rotation direction of the rotary disk 110 as it is farther from the axis CS. In other words, the outer front surface 148A of the outer pushing portion 128e is disposed in front of the inner front surface 154A of the inner pushing portion 128i in the forward rotation direction of the rotary disk 110. The inner front surface 154A is formed by a flat surface facing the peripheral side of the rotating disk 110.
Here, the outer front surface 148A of the outer pushing portion 128e is positioned in front of the inner front surface 154A of the inner pushing portion 128i in the forward rotation direction of the rotary disk 110, as shown in FIG. When pressed by the roller 144A while being in contact with the inner peripheral surface 120, the contact P1 between the coin C and the outer front surface 148A is positioned forward in the forward rotation direction with respect to the inner front surface 154A, and the inner front surface 154A and the coin C means no contact.
When the coin C is pushed and brought into contact with the roller 144A as the outer pushing portion 128e and the inner peripheral surface 120 of the guide circular hole 118, the axis CS and the roller 144A are centered on the axis CS of the rotating disk 110. and located heart CC in the coin C on the inside (close to the axial center CS side) than the imaginary circle IC to the radial distance between the contact point P1 of the coin C. In other words, the contact point P1 between the outer pushing portion 128e and the peripheral surface of the coin C is located farther from the center CC of the coin C with respect to the axis CS of the rotating disk 110. A pressing force F1 acts on the center CC of the coin C from the contact point P1. Further, since the inner front surface 154A of the inner pushing portion 128i and the coin C are not in contact with each other, the pushing force against the coin C does not act. In other words, when the coin C is pushed by the roller 144A while being in contact with the inner peripheral surface 120, the coin C is pushed through the coin passage 140 while receiving a force toward the axis CS from the roller 144A. The coin C is rotated along the coin passage 140 while receiving a force in a direction away from the inner peripheral surface 120 of the guide circular hole 118.

Next, the gap regulating unit 134 will be described.
The gap regulating portion 134 has a function of positioning the rotary disk 110 at a predetermined interval with respect to the base 106. In the first embodiment, a central downward projection that projects downward on the lower surface of the central portion of the disc body 124. 162. The central downward projection 162 is formed by an outwardly- facing surface formed flush with the periphery of the through-hole 126A and an arc-shaped convex surface 162i positioned below the root of the rib 138A, and is formed in a petal shape as a whole. Yes.
An inner escape groove 168A is formed between the gap regulating portion 134 and the inner pushing portion 128i for allowing the inner regulator 112i to escape.
If the coin C can be rotated without the central downward protrusion 162, the central downward protrusion 162 need not be provided.

Next, the extruding portion 142A will be described.
The push-out portion 142A has a function of pushing the coin C between the guide body 114 and the flip roller 116. In the first embodiment, the push-out portion 142A is a back surface of the disk main body 124 and is a roller 144A in the forward rotation direction of the rotary disk 110. It is formed by a part of the downward projection 166A formed at the rear position, and has a wedge shape in the back view. The end of the protrusion 166A on the side of the through-hole 126A is located at the periphery of the through-hole 126A and constitutes an arcuate outer rear surface 152A. Further, in the first embodiment, the pushing portion projection 166A has a circumferential surface on the roller 144A side that protrudes from the vicinity of the circumferential surface of the roller 144A toward the circumferential edge of the rotating disk 110, and the pushing portion is a curved surface or a straight line that moves away from the axis CS of the rotating disk 110. 142A is formed. In other words, the outer peripheral edge 168A of the extrusion projection 166A is formed in an arc shape centering on the axis CS of the rotating shaft 130, and is a ridge extending in an arc shape along the outer peripheral edge of the corresponding through hole 126A. is there.
The outer rear end 153A, which is the rear end portion in the forward rotation direction of the push-out projection 166A, has a function of pushing the coin C when the rotating disk 110 is reversed. It is formed at the outermost edge and has a pointed shape. This is because the coin C is drawn into the guide circular hole 118 as much as possible.

Next, the setting body 112 will be described with reference to FIGS.
The setting body 112 has a function of guiding the coin C, which is pushed through the coin passage 140 by the pushing portion 128, in the circumferential direction of the rotary disk 110. In the first embodiment, the base 106 And a pair of an inner regulator 112i and an outer regulator 112e that protrude upward. The inner regulating body 112i and the outer regulating body 112e are substantially equally spaced between the gap regulating portion 134 and the guide body 114, and are tangent L (see FIG. 5) between the gap regulating portion 134 and the outer peripheral surface of the guide body 114. 2), and the tip portions thereof can pass through the outer escape groove 158 or the inner escape groove 168, respectively. Since the inner regulator 112i and the outer regulator 112e have the same configuration, the outer regulator 112e will be mainly described as a representative.
The outer setting body 112e is fixed to a free end of a plate spring 170 having one end fixed to the back surface of the base 106, and the plate spring 170 is made of spring steel, a composite structure having spring properties, resin, or the like. .

The plate spring 170 has a square shape in plan view, and is fixed to the back surface of the base 106 by a screw (not shown) that passes through the mounting hole 172 at one end thereof.
A circular first normal body through hole 174 and a second normal body through hole 176 are perforated in the attachment portion 178 at the other end of the leaf spring 170 at a predetermined interval.
A circular first riding auxiliary body through hole 180 and a second riding auxiliary body through hole 182 are arranged on the downstream side in the normal rotation direction of the rotating disk 110 of the first standard body through hole 174 and the second standard body through hole 176, respectively. Has been.

A support plate 184 is fixed to the leaf spring 170 at a predetermined interval in parallel with the attachment portion 178.
In other words, between the first normal body through hole 174 and the second normal body through hole 176 of the leaf spring 170, and between the first ride auxiliary body through hole 180 and the second ride auxiliary body through hole 182. Ategai the support plate 184 to the lower end surface of the spacer 18 6 fixed to the lower surface of the leaf spring 170 are fixed by screwing a screw 189 to the scan spacers 18 6.

  A circular first caulking hole (not shown) and a second caulking hole 199 are perforated in the support plate 184 relative to the first normal body through hole 174 and the second normal body through hole 176, and the first caulking hole is formed in the first caulking hole. The support shaft 190 and the second support shaft 192 are fixed with their lower end portions crimped. The first support shaft 190 and the second support shaft 192 are made of metal, such as stainless steel, and have the same shape.

That is, as shown in FIG. 6B, a large-diameter portion 194 is formed in the middle, and the support plate 184 is sandwiched between the large-diameter portion 194 and the caulked lower end portion, whereby the first support shaft 190 is formed. The second support shaft 192 is fixed to the support plate 184 in a suspended state.
A first setting body 196 and a second setting body 198 are supported on the first support shaft 190 and the second support shaft 192.
In the first embodiment, the first normal body 196 and the second normal body 198 are integrally formed of a soft material than the coin C, for example, a resin superior in mechanical strength and wear resistance, specifically a polyacetal resin. Yes. Further, the first setting body 196 is the first roller 200, and the second setting body 198 is the second roller 202, which can rotate about the vertical axis of the first support shaft 190 or the second support shaft 192, respectively. It is supported. However, the first setting body 196 and the second setting body 198 may be fixed without being rotatable.

In the first embodiment, the first roller 200 and the second roller 202 have an inverted bottomed cylindrical shape, and are respectively covered with the first support shaft 190 or the second support shaft 192. Each of the first roller 200 and the second roller 202 has a large-diameter flange portion 204 having substantially the same diameter as the large-diameter portion 194 at the lower end, and the upper portion is a small-diameter portion 205 having the same diameter.

Further, an inner regulator 112i is configured by covering the first support shaft 190 with the first roller 200, and an outer adjuster 112e is configured by covering the second support shaft 192 with the second roller 202.
As shown in FIG. 6A, when the support plate 184 is fixed to the back surface of the leaf spring 170, a gap is formed between the upper surface of the large-diameter flange portion 204 and the back surface of the leaf spring 170. The first roller 200 and the second roller 202 are restricted from moving in the thrust direction, and thus in the downward direction.
As a result, the first roller 200 and the second roller 202 are supported by the leaf spring 170 so as to be rotatable around the vertical axis and without falling off.

The first mounting hole 206 and the second mounting hole 208 are rectangular and are formed on the downstream side of the support plate 184 in the forward rotation direction of the rotary disk 110 with respect to the first support shaft 190 and the second support shaft 192.
The lower end portions of the rectangles of the first riding assistance body 210 and the second riding assistance body 211 are inserted into the first mounting hole 206 and the second mounting hole 208, respectively.

Since the first riding assistance body 210 and the second riding assistance body 211 have the same structure, the same components are denoted by the same reference numerals as the second riding assistance body 211.
The first riding assistance body 210 and the second riding assistance body 211 are integrally formed of a soft material, such as a resin having a higher mechanical strength and wear resistance than the coin C, specifically, a polyacetal resin. ing. Even if the coin C is pressed against the first riding assistance body 210 or the second riding assistance body 211 with a large force, the first riding assistance body 210 or the second riding assistance body 211 is This is because the coin C is not deformed.

That is, as shown in FIG. 6B, the upper part is a small-diameter cylindrical part 212, the lower part is a large-diameter cylindrical part 214, and a step part 216 is formed at these boundaries.
A rectangular portion 218 is formed by cutting off both sides of the lower end portion of the large-diameter cylindrical portion 214. By inserting the rectangular portion 218 into the first mounting hole 206 and the second mounting hole 208, the first riding assistance body 210 and the second riding assistance body 211 are prevented from rotating. When the support plate 184 is attached to the leaf spring 170, the stepped portion 216 contacts the lower surface of the leaf spring 170, and the first riding assistance body 210 and the second riding assistance body 211 are prevented from coming off.

The top portions 220 of the first riding assistance body 210 and the second riding assistance body 211 are formed in a hemispherical shape. That is, when the leaf spring 170 is fixed to the back surface of the base 106, the top 220 is set so as to slightly protrude from the top surface of the base 106. Specifically, the hemispherical portion constituting the top portion 220 protrudes from the upper surface of the base 106. As a result, when the rotating disk 110 is reversed, the coin C positioned in the through hole 126 rides on the first riding assistance body 210 and the second riding assistance body 211 due to the inclination of the spherical surface, and as a result, the inner regulation The body 112i and the outside body 112e can be overcome. Thereby, the rotating disk 110 can be reversed. In addition, when the top part 220 of the 1st riding assistance body 210 and the 2nd riding assistance body 211 is formed in a slope, when the rotating disk 110 is reversed, the coin C can ride on the said slope. The first roller 200 and the second roller 202 protrude from the upper surface of the base 106 in substantially the same amount as the first riding assistance body 210 and the second riding assistance body 211, respectively.
The interval between the inner setting body 112i and the outer setting body 112e is formed such that the amount of depression of the peripheral surface of the coin C does not drop more than a predetermined amount, and is guided by them and is connected to the inner pushing portion 128i or the outer pushing portion 128e. When pushed, it is configured not to be pressed by a large force against the inner setting body 112i and the outer setting body 112e.

Next, the guide body 114 will be described.
The guide body 114 has a function of guiding the coin C pushed by the pushing portion 128 after the coin C is guided by the setting body 112, and the forward position of the rotary disk 110 in the forward rotation direction at the outlet opening 122. And is attached to the base 106 in a substantially fixed state. In other words, the coin C does not move with the force pushed in the normal state by the pushing unit 128, but is elastically supported so as to retreat when pushed with a larger force. In the first embodiment, the guide body 114 is disposed at a position close to the periphery of the rotating disk 110, but may be positioned below the periphery of the rotating disk 110.

Next, the flip roller 116 will be described.
The flip roller 116 has a function of pinching the coin C between the guide body 114 and flipping it out. In the first embodiment, one end of the flip roller 116 is rotatably supported by a shaft protruding downward from the lower surface of the base 106. The lever 221 is rotatably attached to a support shaft 224 that protrudes upward from the other end of the lever 221 and passes through an arc-shaped elongated hole 222 formed in the base 106 and protrudes toward the upper surface side of the base 106.
In a normal state, the flip roller 116 is kept stationary with a predetermined interval equal to or smaller than the diameter of the coin C with respect to the guide body 114 and is elastically biased toward the guide body 114 side by a spring 225. . When the coin C is pushed between the guide body 114 and the flip roller 116, the flip roller 116 is moved away from the guide body 114 against the spring force of the spring 225, and then the center of the coin C is Immediately after crossing the straight line connecting the contact point between C and the guide body 114 and the contact point between the coin C and the flip roller 116, it is ejected away from the rotary disk 110 by the elastic force urged by the flip roller 116. .

Next, the guide circular hole 118 will be described.
The guide circular hole 118 has a function of guiding the coin C pushed by the pushing portion 128 of the rotating disk 110, specifically, the outer pushing portion 128e, and penetrates the guide body 108 from the upper side to the lower side. The depth of the hole is slightly deeper than the thickness of the thickest coin expected to be used. The diameter of the guide circular hole 118 is substantially the same as the diameter of the rotating disk 110. Therefore, the guide circular hole 118 is a circular hole disposed outside the pushing portion 128.

Next, the outlet opening 122 will be described.
The outlet opening 122 is an opening formed between the left end portion 118L and the right end portion 118R of the guide body 108, and is substantially a space formed between the guide body 114 and the flip roller 116. is there.

Next, the outlet guide body 226 will be described with reference to FIG.
The outlet guide body 226 has a function of guiding the coin C from the guide circular hole 118 to the flip roller 116 side. In the first embodiment, the base 10 between the end of the guide circular hole 118 and the flip roller 116 is provided. 6 is a roller that is rotatably attached to the tip of a fixed shaft 228 that is suspended with respect to 6, and guides the coin C pushed by the outer pushing portion 128e from the inner peripheral surface 120 to the flipping roller 116.

Next, the coin sensor 230 will be described.
The coin sensor 230 has a function of detecting the coin C ejected by the flip roller 116, is arranged in relation to the movement path of the coin C ejected, and can employ a photoelectric sensor, a metal sensor, or the like.

Next, the operation of the first embodiment will be described with reference to FIGS.
Since the coins C retained in the coin retention container 102 are agitated by the rotation of the rotating disk 110 and assume various postures, they fall one by one into the through holes 126 (126A to 126F). The coin C that has fallen into the through-hole 126 is brought into surface contact with the base 106 and is pushed by the roller 144 as the inner pushing portion 128i or the outer pushing portion 128e to be rotated along the coin passage 140.
When the coin C is pushed by the outer front surface 148 of the roller 144, as shown in FIG. 8, the coin C is guided by the inner peripheral surface 120 of the guide circular hole 118, and the inner front surface 154 of the inner pushing portion 128i Does not touch. Therefore, since the contact point P1 between the peripheral surface of the coin C and the roller 144 is located outside the center CC of the coin C (a position far from the axis CS), the coin C has a vector toward the axis CS side. It is swung around in the acted state. In other words, so that the peripheral surface of the coin C is floated from the inner peripheral surface 120 of the guide circular hole 118, in other words, sliding with the contact pressure between the coin C and the inner peripheral surface 120 being smaller than the conventional one. Therefore, the pressure of the coin C is reduced, and the coin C is not plastically deformed.
When the coin C pushed by the roller 144 approaches the outlet opening 122, after being guided by the outlet guide body 226 and contacting the flip roller 116, the coin C is guided by the flip roller 116 and moved to the guide body 114 side. (Figure 9).
Then, the coin C is pushed between the guide body 114 and the flip roller 116, and finally in the process of being pushed by the pushing portion 142, the contact P3 between the coin C and the guide body 114, the coin C and the flip roller 116, The straight line L2 connecting the contact point P4 of the coin C is ejected by the resilience applied to the flip roller 116 immediately after the center CC of the coin C passes (FIG. 10). The coin C ejected is detected by the coin sensor 230 and is used for controlling the number of coins C to be dispensed.

  In some rare cases, the coin C may be pushed only by the inner front surface 154 due to the influence of the coins C stacked in bulk. In this case, since the coin C does not contact the inner peripheral surface 120, plastic deformation does not occur. Further, the coin C is guided by the first roller 200 or the second roller 202, which is the setting body 112 (FIG. 11), pushed between the guide body 114 and the flip roller 116, and is ejected by the flip roller 116 in the same manner as described above. (Figure 10).

When the rotating disk 110 is reversed, for example, when the coin C is sandwiched between the back surface of the rotating disk 110 and the base 106 for some reason and the rotation of the rotating disk 110 stops, the rotating disk 110 rotates in the forward direction. Is stopped and rotated in the reverse direction for a predetermined time. That is, in FIG. 12, when the rotating disk 110 rotates clockwise, the coin C located in the through hole 126 is pushed and rotated by the inner front surface 154 or the outer rear surface 152 of the inner pushing portion 128i. .
In particular, the coin C that is being paid out at the outlet opening 122 is pushed by the outer rear end 153 of the push-out projection 166. By this pushing operation, the coin C having the center CC located on the inner side (axial center CS side) of the rotation trajectory of the outer rear end 153 is pulled into the guide circular hole 118, whereby the rotating disk 110 is continuously reversed. (Figure 12).

  The rotating disk 110 is automatically restarted after the reverse rotation, and the rotating disk 110 is rotated forward and the coin clogging is eliminated, so that the coin C can be continuously paid out.

Next, Embodiment 2 will be described with reference to FIG.
The second embodiment has the same configuration as that of the first embodiment except that the outer pushing portion 128e is a fixed body 232 fixed to the back surface of the rotating disk 110. In the second embodiment, the fixed body 232 is a cylindrical body and is fixed downward on the disk main body 124, and thus on the back surface of the rotating disk 110. In addition to the cylindrical shape, the fixed body 232 may have a flat surface or a pointed shape at the portion that contacts the coin C as in the case of the inner pushing portion 128i. In the forward rotation direction of 110, in the state where the coin C is positioned forward and outside the axis CS of the rotating disk 110, and the coin C is guided to the guide circular hole 118, it is outside the center CC of the coin C. What is necessary is just to satisfy the conditions for forming a contact point with the peripheral surface of the coin C. As long as these conditions are satisfied, the same effects as those of the first embodiment are exhibited. However, in the first embodiment, the coin C and the outer pushing portion 128e are rolling pairs, whereas in the second embodiment. The difference is that it is a slip pair. Note that the protrusion 234 corresponding to the pushing portion protrusion 166 is integrated with the fixed body 232, but can be configured separately from the first embodiment. In addition, the pushing portion 142 is formed in an arc shape in the second embodiment.
