Description

The present invention relates to a coin denomination discriminating apparatus that discriminates one denomination of a plurality of coins received in a rose state one by one.
Specifically, the present invention relates to a coin denomination discriminating apparatus that accurately discriminates the denominations of a plurality of coins received in a rose state.
More specifically, the present invention relates to a coin denomination device that discriminates a plurality of coin denominations received in a rose state one by one according to diameter, material, and thickness.
Furthermore, the present invention relates to a coin depositing / withdrawing apparatus that holds accepted coins of a plurality of denominations in a holding unit for each denomination and pays out a predetermined number of coins of a predetermined denomination in response to a command from a related device. .
The present invention also relates to a small coin deposit / withdrawal apparatus suitable for installation under or next to a POS register.
The “coin” used in this specification includes currency coins, tokens, medals, and the like, and the shape includes a circle and a polygon.

As a first conventional technique, coins are locked one by one by pins protruding on a turntable that rotates in a hopper and sent out to a coin transport path, and in the middle of being transported by pins of a coin transport means in this coin transport path After determining the denomination from the diameter acquired by the coin diameter detection unit, by operating the coin pushing member based on the timing detection means arranged immediately before the coin storage unit of the denomination in the coin transport path and the determination denomination It is known to drop a coin of a predetermined denomination into a corresponding coin storage unit (see, for example, Patent Document 1).

As a second prior art, a resin wiper is rotatably provided between a base case made of a plastic molded product and a lid, and a detection coil is disposed on each of the base case and the lid, and the central portion from the outer peripheral side of the wiper. It is known that data relating to the material and diameter of a metal medal is acquired by the detection coil by pressing the medal against the reference surface of the wiper with a guide piece having an arcuate guide portion toward the surface (for example, Patent Document 2).

Japanese Patent No. 2769410 (Fig. 1-5, pages 2-4) Japanese Patent No. 3198288 (Fig. 1-5, pages 1 to 3)

In the first prior art, since coins are sorted by denomination only by the diameter from the coin diameter detecting device, there is a problem that the accuracy of denomination sorting is low.
In other words, when coins are identified only by diameter, if the diameters are the same, they are identified as genuine coins regardless of the material and thickness, and it is determined that the denomination is equivalent to the diameter. There was a problem that could not be done.
Moreover, in the said prior art, the coin diameter detection apparatus is comprised by the optical sensor.
The reason for this is that a metal chain is used as the coin transfer means, so when using a magnetic sensor that is mainly used for coin denomination, the magnetic sensor is affected by the chain and makes a highly accurate determination. This is because there is a problem that cannot be done.

In the second prior art, when the processing speed of coin discrimination is increased, the medal is elastically pressed from the outer periphery to the center of rotation, so that the medal may be separated from the reference plane by centrifugal force, and high accuracy detection is possible. There is a fear that it cannot be done.
Further, when coins having different diameters are used, there is a problem that the accuracy of diameter detection is low because the guide portion of the medal is arcuate.
In other words, when different types of coins having different diameters are discriminated, there is a risk of erroneous determination.

A first object of the present invention is to provide a coin denomination discriminating apparatus that can accurately discriminate denominations of multi-denomination coins.
The second object of the present invention is to provide a coin denomination discriminating apparatus that has high coin discrimination accuracy and is suitable for a small coin depositing apparatus.

In order to achieve this object, the denomination device for coins according to the invention of claim 1 is configured as follows.

A rotating body having a coin receiving portion, a magnetic sensor relatively disposed on one side of the moving passage of the coin receiving portion and on the opposite side of the moving passage, and a reference guide for guiding coins disposed on the outer periphery of the moving passage. That it contains a denomination discriminating device of a coin, characterized in.

In this configuration, the coins received in a loose state are received one by one in a semicircular receiving portion constituted by a concave portion of the plate whose upper surface and peripheral surface are released by the rotation of the rotating plate and the extruded body. The accepted coin is sent out in the circumferential direction of the rotating plate by the movement of the extruded body. The fed coins are received one by one in the concave coin receiving portion of the rotating body rotated in conjunction with the rotating plate, and are moved through the moving path by the rotation of the rotating body. In the process of moving through the movement path, the coins located in the coin receiving part pass between the magnetic sensors disposed relatively on one side and the opposite side of the movement path.

Since the magnetic sensor is disposed on one side and the other side of the coin, the characteristics of the metal coin can be obtained with high accuracy.
Further, for the coins moved by the rotating body, data for determination is acquired by the magnetic sensor while being guided by the reference guide located on the outer periphery of the rotating body.
Thereby, since the coin is guided while being pressed against the reference guide by centrifugal force, even if the rotational speed of the rotating body is increased, in other words, even when the coin discrimination speed is improved, Never leave the reference guide.
Therefore, since the positional relationship between the magnetic sensor for collecting the coin discrimination data guided by the reference guide and the coin of the predetermined denomination is the same, the data obtained from the magnetic sensor is highly accurate and the discrimination accuracy is increased. There are advantages.

The invention according to claim 2 is a denomination discriminating apparatus that acquires data for denomination discrimination while moving coins received in a loose state one by one to a predetermined position, and the rotating plate is configured to receive the coins one by one. The receiving part has a receiving part, and the receiving part has a recess and an extruded body formed on a plate fixed on a rotating disk, and has a circumferential surface and an upper surface opened to hold a coin in the receiving part. And separating and feeding the extruded body toward the circumferential surface side to push the extruded body from the circumferential surface side opening in the circumferential direction of the rotating plate, and the outer peripheral side of the rotating plate A receiving body that receives and guides coins sent out from the receiving portion by the pusher, and a coin receiving portion that has an opening on the peripheral side, and is rotated in synchronization with the rotating plate. Body and guided by the receiver In order to guide the coins received and moved by the coin receiving portion of the rotating body, a reference guide having a linear guide portion disposed on the outer periphery of the rotating body and the coin receiving portion are received. And a denomination device for coin denomination, comprising: a magnetic sensor disposed on one side of the movement path of the coin guided by the linear guide part and on the opposite side of the one side. It is.

In this configuration, the coins received in a loose state are received one by one in the receiving portion formed by the concave portion of the plate and the extruded body whose upper surface and peripheral surface are released by the rotation of the rotating plate. The accepted coin is sent out in the circumferential direction of the rotating plate by the movement of the extruded body. The fed coins are guided by the receiving body, received one by one in the concave coin receiving portion of the rotating body rotated in conjunction with the rotating plate, and moved while being guided by the reference guide by the rotation of the rotating body. In the process of guiding the coins to the straight guide part, the coins located in the coin receiving part pass between magnetic sensors that are relatively arranged on one side and the opposite side. Since the magnetic sensor is disposed on one side and the other side of the coin, the characteristics of the metal coin can be obtained with high accuracy.
Further, the coin is brought into close contact with the linear reference guide portion by centrifugal force, and is guided along its peripheral surface to move linearly. Therefore, since the magnetic sensor is arranged relative to the reference guide portion, it is only necessary to arrange the magnetic sensor with respect to the coin that moves linearly, and it is possible to accurately detect the diameters of coins of a plurality of denominations. Can do.

This example accepts coins of 8 denominations of 2 euros, 1 euro, 50 cents, 20 cents, 10 cents, 5 cents, 2 cents and 1 cent, which are European Community currencies, and holds them for each denomination. This is an example of using a coin denomination device of a coin depositing / dispensing device that dispenses a predetermined number of coins of a predetermined denomination based on a payout instruction.
However, it can also be used for a coin deposit machine that accepts coins of multiple denominations and holds them for each denomination.
An outline of the coin depositing and dispensing apparatus 100 will be described with reference to FIG.
The coin deposit / withdrawal device 100 includes a deposit amount regulating device 102, a separation / delivery device 104, a denomination discriminating device 106, a transport device 108, a sorting unit 110, a holding unit 112, and a withdrawal device 114.

First, the deposit amount regulating apparatus 102 will be described.
The deposit amount regulating device 102 has a function of sending coins of a plurality of denominations inserted into the insertion port 120 in a loose state to the separation and delivery device 104 in the next process within a range not exceeding a predetermined amount per unit time.
Specifically, it includes a deposit flat belt 122, a break roller 124, and an electric motor 126 that drives the deposit flat belt 122.
The deposit flat belt 122 has a width of about twice the maximum coin diameter, is stretched between a pair of rollers, and is slightly inclined upward.

The deposit flat belt 122 is movable in the forward direction in which the coins are conveyed forward by the electric motor 126 and in the reverse direction in which the coins are returned.
The crushing roller 124 is disposed above the intermediate portion of the deposit flat belt 122 with a gap about three times that of the thinnest coin between the flat belt 122.
When the deposit flat belt 122 travels in the transport direction, the crushing roller 124 rotates in the direction opposite to the travel direction of the deposit flat belt 122, and when the deposit flat belt 122 moves in the return direction, It is comprised so that it may become.

However, when the deposit flat belt 122 moves in the return direction, it may be rotated so that the lower surface of the breaking roller 124 returns in the same direction.
As a result, when three or more thinnest coins overlap on the flat belt 122 and arrive at the breaking roller 124, the uppermost coin is moved back in the return direction by the breaking roller 124, and a large amount of coins are separated at once. The delivery device 104 is restricted so as not to fall.

A photoelectric sensor 128, which is a deposit detection device, is arranged so that the optical axis crosses slightly above the deposit flat belt 122 below the slot 120.
When the optical axis of the photoelectric sensor 128 is interrupted, it is considered that a coin has been inserted, and the motor 126 is driven to move the deposit flat belt 122 in the deposit direction.
Further, when a full sensor of the separation and delivery device 104 described later detects a full state, the motor 126 is stopped.
Therefore, the separation and delivery device 104 can receive the coins of the full amount or more from the deposit amount regulating device 102, and can stably send out the coins one by one.
Note that the deposit detection device can also detect by a magnetic sensor installed under the deposit flat belt 122.

Next, the separation / delivery device 104 will be described.
The separation / delivery device 104 has a function of separating coins of a plurality of denominations received from the deposit amount regulation device 102 in a loose state one by one and sending them to the next process.
The separation / delivery device 104 is disposed below the deposit amount regulating device 102 and includes a rotating plate 130, a holding bowl 132, a receiving body 134, and a full sensor 136 as shown in FIGS.

The rotating plate 130 has a receiving portion 138 that receives coins one by one, is inclined at a predetermined angle, and is rotated at a predetermined speed.
In this receiving portion 138, a Y-shaped plate 146 having three concave portions 142 formed at equal intervals on the upper surface of the rotating disc 140 is fixed concentrically with the disc 140.
Note that when the diameter of the disc 140 is increased, the number of the receiving portions 138 can be 4 or more, and when the diameter of the disc 140 is reduced, the number of the receiving portions 138 can be 2 or less.

However, increasing the diameter of the disc 140 is not preferable because it leads to an increase in the size of the coin deposit / withdrawal device 100. If the number of receiving portions 138 is less than 3, the number of coins sent out per unit time is reduced. Since it takes time to deposit coins, the number of receiving units 138 is most preferably three.
In addition, an extruded body 148 that pivots is disposed on one side of the recess 142.
In other words, a substantially semicircular receiving portion 138 is formed by the extruded body 148 and the concave portion 142.

The receiving unit 138 is set to a size that cannot accept two coins having the smallest diameter and that accepts only one coin having the largest diameter.
The extrudate 148 is normally positioned at a position close to one side of the recess 142 so as to form a receiving portion 138, and when it is pivoted to move to a predetermined position, the held coin is disc-shaped. Sends out in 140 circumferential directions.
The movement of the extruded body 148 is preferably performed by a groove cam or the like using the rotational movement of the disc 140.

The receiving part 138 of the rotating plate 130 receives the coins held in a separated state in the lower part facing the holding bowl 132 one by one, and the extruded body 148 receives the coins of the receiving part 138 at a predetermined position above the rotation center. Extruded in the circumferential direction and delivered to the knife-shaped receiver 134.
As shown in FIG. 4, the rotating plate 130 passes through a driven gear 158 formed on the lower peripheral surface of the disc 140 by a gear 154 that is rotated through a speed reducer 152 by an electric motor 150 arranged on the side. It is rotated at a predetermined speed.

The full sensor 136 has a function of outputting a full signal when the amount of coins in the storage bowl 132 exceeds a predetermined amount, and is, for example, a transmissive photoelectric sensor.
When the amount of coins in the storage bowl 132 is larger than a predetermined amount, the effect of coin agitation by the Y-shaped plate 146 and the extruded body 148 is reduced, so that the disadvantage of reducing the coin receiving efficiency to the receiving unit 138 is solved. It is.
When the full sensor 136 outputs a full signal, the electric motor 126 is stopped, and the supply of coins from the deposit amount regulating apparatus 102 is stopped.
When the full sensor 136 stops outputting a full signal, the electric motor 126 is restarted and the coins on the deposit flat belt 122 are supplied to the holding bowl 132.

Next, the denomination discriminating apparatus 106 will be described with reference to FIGS.
The denomination discriminating device 106 has a function of discriminating the authenticity and denomination of the coins sent out one by one from the separation and delivery device 104.
The denomination discriminating device 106 has a function of discriminating the authenticity and denomination of coins based on the detection data acquired from the magnetic sensor 160.
Specifically, it has a function of discriminating the authenticity and denomination of a coin based on detection data from a coin material sensor 162, a thickness sensor 164, and a diameter sensor 166.
The denomination discriminating apparatus 106 uses a signal from a material sensor 162, a thickness sensor 164, and a diameter sensor 166 composed of a coil and a ferrite core having a predetermined shape to discriminate the authenticity and denomination of coins.

The denomination discriminating apparatus 106 includes a magnetic sensor 160, a slide base 170 disposed in the same plane as the upper surface of the disc 140, a rotating body 172 for feeding coins, and a reference guide 174.
First, the slide base 170 will be described.
The slide base 170 is disposed to be inclined on the upper surface of the base 178, and has a function of guiding one surface of the coin pushed by the rotating body 172.
The slide base 170 is a bottom surface of a circular hole 180 formed on the top surface of a flat base 178 formed of a nonmagnetic material, for example, resin, and the surface thereof is planar.
However, it is possible to reduce the sliding resistance of the coin by providing the slide base 170 with a ridge extending in the coin moving direction.

Next, the rotating body 172 will be described.
The rotating body 172 has a function of moving the coins received from the sending / separating device 104 and passing the magnetic sensor 160 part by one.
Furthermore, the rotator 172 delivers the coin that has passed through the magnetic sensor 160 to the transport device 108.
The rotating body 172 is formed of a non-magnetic material, for example, resin, is fixed to a rotating shaft 182 protruding at the center of the circular hole 180, is parallel to the slide base 170, and is rotatable in a close plane. is there.
The rotating body 172 forms a coin receiving portion 185 by three pushing levers 184 arranged at the same number of intervals as the receiving portion 138, and has a Y shape.

Next, the reference guide 174 will be described.
The reference guide 174 has a function of linearly guiding coins passing relative to the magnetic sensor 160 and making the position of the denominated coin relative to the magnetic sensor 160 constant.
The reference guide 174 has an arcuate portion 186 formed following the receiving body 134 and a linear guide portion 188 formed following the arcuate portion 186. The reference guide 174 is located on the outer periphery of the rotation path of the rotating body 172, and is a pushing lever. The coin pushed by 184 is guided.
The reference guide 174 is preferably molded from polyoxymethylene, which is a resin with excellent wear resistance in order to guide coins.
Further, the reference guide 174 can be formed integrally with the slide base 170 in order to improve manufacturing efficiency and accuracy.

Next, the magnetic sensor 160 will be described.
The magnetic sensor 160 has a function of acquiring data for determining the authenticity and denomination of a coin guided by the reference guide 174.
The magnetic sensor 160 is disposed above and below a coin movement path 190 that is moved by the pushing lever 184 while being guided by the reference guide 174.

The magnetic sensor 160 includes a diameter sensor 166, a thickness sensor 164, and a material sensor 162.
The diameter sensor 166 has a function of acquiring data relating to the diameter of the coin moved by the rotating body 172.
Euro coins are 8 denominations, and 2 euro coins with the maximum diameter is about twice the minimum 1 cent, so it is difficult to obtain highly accurate data with only one diameter sensor.
Therefore, in this embodiment, it is constituted by a plurality of diameter sensors.
Specifically, the first diameter sensor 192, the second diameter sensor 194, and the third diameter sensor 196 are configured.

As shown in FIGS. 5 and 6, the material sensor 162, the thickness sensor 164, and the second diameter sensor 194 include a cylindrical central tube 198 and a center of a core 202 made of ferrite having a substantially cylindrical outer wall 200 surrounding the outer periphery. The magnetic sensor is configured by winding a coil 204 around a cylinder 198.
The magnetic sensor can be composed of a coil, a core, a high-frequency application circuit, etc., so it can obtain highly accurate data, but it is highly available and inexpensive. Suitable for equipment.

As shown in FIG. 5, the first diameter sensor 192 and the third diameter sensor 196 are formed in a substantially rectangular shape having an outer wall from which the outer wall 200 corresponding to the cylindrical central tube 198 and the straight guide portion 188 is removed. Yes.
This is because the rectangular shape allows the first diameter sensor 192 and the third diameter sensor 196 to be arranged close to each other, and data for highly accurate discrimination can be obtained.

Each of the magnetic sensors 162, 164, 192, 194, and 196 is fixed by an adhesive or the like by fitting the hole of the central cylinder 198 with a cylindrical positioning pin 206 protruding from the back surface of the slide base 170.
Since the position of the sensor is determined by the positioning pin 206 and the hole of the central cylinder 198, there is an advantage that the position of the sensor can be easily and accurately positioned.

The thickness sensor 164 and the second diameter sensor 194 are disposed in the immediate vicinity of the receiving body 134 and are disposed on the first straight line L1 orthogonal to the straight guide portion 188.
The thickness sensor 164 is disposed near the reference guide 174, and the end surface of the central cylinder 198 faces the coin surface of all denominations.
The second diameter sensor 194 is disposed so as to be opposed to about a quarter of the maximum diameter 2 euro coin, and is disposed at a position facing substantially the entire surface of the distinguishable maximum diameter coin.
The material sensor 162 is disposed on the line L2 downstream of the straight line L1 and substantially orthogonal to the straight guide part 188.
The first diameter sensor 192 and the third diameter sensor 196 are disposed on the third straight line L3 that is immediately downstream of the second straight line L2 and substantially orthogonal to the straight guide portion 188.

The extension line of the coin push-out portion 206 of the push lever 184 of the rotating body 172 is set to intersect at an acute angle until the maximum diameter portion of the coin faces the material sensor 162, the first diameter sensor 192, and the third diameter sensor 196. It is.
The material sensor 162 is disposed in the immediate vicinity of the reference guide 174, and the end surface of the central cylinder 198 faces the surface of all denomination coins.
The first diameter sensor 192 is disposed so as to be slightly opposed to the upper part of the minimum diameter one-cent coin guided by the linear guide 188.
The third diameter sensor 196 is arranged so that the lower half of the magnetic sensor 196 faces the upper end portion of the 2 euro coin when the maximum diameter 2 euro coin faces.

The thickness sensor 164, the material sensor 162, the first diameter sensor 192, the second diameter sensor 194, and the third diameter sensor 196 are each composed of a pair of sensors disposed above and below the coin movement path 190.
One of the pair of sensors is fixed to the back surface of the slide base 170, and the other is fixed to the upper cover 208.

Next, the upper cover 208 will be described.
The upper cover 208 is pivotally attached to a shaft 210 disposed above the separation delivery device 104 and to the side of the circular hole 180.
The upper cover 208 has a trapezoidal shape in plan view, and the lower surface 212 is flat, and a part thereof is positioned in surface contact with the upper surface of the reference guide 174.
In other words, the distance between the slide base 170 and the lower surface 212 is kept parallel at a small interval by the surface contact between the lower surface 212 of the upper cover 208 and the upper surface of the reference guide 174.
The interval between the slide base 170 and the lower surface 212 is set by adding a margin to the maximum thickness of the coins to be handled.
The upper cover 208 is fixed by the hook 214 while being in surface contact with the upper surface of the reference guide 174.

Therefore, in the denomination discriminating apparatus 106, the coin is pushed by the pushing lever 184 through the thin moving passage 190 defined by the slide base 170, the lower surface 212 and the reference guide 174.
The thickness of the pushing lever 184 is slightly smaller than the distance between the slide base 170 and the lower surface 212, and slightly thicker than the thickness of the maximum thickness coin.
This is for improving strength and wear resistance and facilitating production.
A gear 216 is fixed to a lower end portion of the rotating shaft 182 that penetrates the slide base 170 and meshes with the driven gear 158.

The gear ratio of the driven gear 158 and the gear 216 is 1: 1, and the pushing lever 184 pushes the received coin immediately after the pusher 148 pushes the coin outward of the receiving portion 138 and delivers it to the receiving member 134. Timing is set to push.

Next, the timing sensor 176 will be described.
The signal output from the timing sensor 176 every time the pushing lever 184 passes is used as an association signal for storing the authenticity of coins and the discrimination information of the denomination determined based on the data detected by the magnetic sensor 160. It is done.
The timing sensor 176 is fixed to the base 178.
In the embodiment, the timing sensor 176 is a reflective photoelectric sensor, and outputs an “H” push lever timing signal when opposed to the push lever 184, and outputs an “L” signal when not opposed.

Next, the conveying device 108 will be described.
The transport device 108 has a function of transporting the coins whose authenticity and denomination have been determined to the sorting unit 110.
The transfer device 108 includes an endless transfer body 220 that moves in the same plane in one direction, and one surface of a coin that is pushed by the endless transfer body 220 slides, and a slide that is positioned in the same plane that includes the slide base 170. A plate 224 and a straight guide rail 226 for guiding the peripheral surface of the coin are included.
In other words, the slide plate 224 is inclined at the same angle as the slide base 170.
This inclination angle is preferably about 45 degrees in order to reduce the size of the coin depositing and dispensing apparatus 100 as a whole.

First, the endless transport body 220 will be described.
In the present embodiment, the endless transport body 220 is a chain 232 that is stretched between the first sprocket 228 and the second sprocket 230 that are arranged at a predetermined interval.
The chain 232 is installed in the shape of a flat running track, and the first sprocket 228 is arranged immediately on the side of the rotating body 172 of the denomination determining device 106.
The chain 232 is preferably a metal chain in terms of durability and cost, but can be made of resin.
Push pins 234 are fixed to the side surface of the chain 232 at a predetermined interval.

A plurality of push pins 234 are attached to the chain 232 at intervals corresponding to the intervals of the push lever 184.
A driven gear 238 is fixed to a lower portion of the shaft 236 to which the first sprocket 228 is fixed, and meshes with a gear 216 that drives the rotating body 172.
The gear ratio between the gear 238 and the gear 216 is 1: 3.
In other words, the push lever 184 and the push pin 234 are linked in a predetermined relationship.
Specifically, the coin pushed to the transfer path 240 of the push pin 234 by the push lever 184 is set to be pushed by the push pin 234 immediately.

Next, the guide rail 226 will be described.
The guide rail 226 has a function of guiding the circumferential surface of the coin so that the coin pushed by the push pin 234 moves on the transfer path 240.
The guide rail 226 is disposed along and slightly below the upper chain of the running track shape.
The guide rail 226 protrudes from the slide plate 224 in a direction orthogonal to the maximum thickness of the handling coin.
Therefore, the lower surface of the coin pushed by the push pin 234 is guided by the slide plate 224, and the lower peripheral surface thereof is guided by the guide rail 226.
As will be described later, the guide rail 226 in this embodiment also serves as a selection unit.

Next, the selection unit 110 will be described.
The sorting unit 110 has a function of dropping coins into predetermined sorting holes for each denomination.
The sorting unit 110 includes an upper sorting unit 250 disposed along the guide rail 226 on the upper side of the guide rail 226, and a lower sorting unit 252 disposed on the lower side along the guide rail 226.

In the upper sorting section 250, a 2 cent sorting hole 254, a 5 cent sorting hole 256, a 10 cent sorting hole 258, a 20 cent sorting hole 260, and an overflow sorting hole 262 are arranged in this order in the traveling direction of the transport device.
In the lower sorting section 252, a reject sorting hole 264, a 1 cent sorting hole 266, a 2 euro sorting hole 268, a 50 cent sorting hole 270 and a 1 euro sorting hole 272 are arranged in order in the traveling direction of the transport device 108. .
In this way, when the upper sorting unit 250 and the lower sorting unit 252 of the transport device 108 are arranged, since the coins can be distributed to the upper side and the lower side at the same place of the transport device 108, the coin transport distance can be shortened, The deposit / withdrawal apparatus 100 can be miniaturized.

In each of the coin sorting holes 254, 256, 258, 260, 264, 266, 268, 270 and 272, an electrically operated gate device (not shown) is arranged.
In the present embodiment, the gate device of the selection holes 264, 266, 268, 270 and 272 also serves as the guide rail 226.
That is, the guide rail 226 includes a fixed guide 274 fixed between the sorting holes 264, 266, 268, 270, and 272, and a movable guide 276 of the gate that is electrically moved, and usually has a linear shape. ing.
When the coins to be conveyed are dropped into the sorting holes 264, 266, 268, 270 and 272, the movable guide 276 is moved from the normal position so that the transferred coin is not guided to the movable guide 276. In this case, it falls into a predetermined sorting hole.

Next, the gate timing sensors 280, 282, 284, 286, 288 and 290 will be described.
The gate timing sensors 280, 282, 284, 286, 288, and 290 have a function of detecting coins that are moved along the transfer path 240 by the transfer device 108.
A first timing sensor 280 is disposed in the passage cover 292 facing the sorting passage 240 guided by the guide rail 226, immediately before the 2-cent sorting hole 254 and the reject sorting hole 264.
A second timing sensor 282 for the 5 cent sorting hole 256 and the 1 cent sorting hole 266 is disposed immediately before the 5 cent sorting hole 256.

A third timing sensor 284 for the 10 cent sorting hole 258 and the 2 euro sorting hole 268 is disposed immediately before the 10 cent sorting hole 258.
A fourth timing sensor 286 for the 20 cent sorting hole 260 and the 50 cent sorting hole 270 is disposed immediately before the 20 cent sorting hole 260.
A fifth timing sensor 288 for the 1 euro sorting hole 272 is arranged immediately before the 1 euro sorting hole 272.
An overflow arrival sensor 290 is disposed immediately before the overflow selection hole 262.
The overflow sorting hole 262 is formed to have a size that allows the largest coin to be used to fall, so that the coin holding unit 112 overflows the coin of a predetermined denomination, and no gate is disposed.

The gate devices facing the respective coin sorting holes 254, 256, 258, 260, 264, 266, 268, 270 and 272 are a first timing sensor 280, a second timing sensor 282, a third timing sensor 284, and a fourth timing sensor. 286, the fifth timing sensor 288, the timing sensor 176, and the magnetic sensor 160 are selectively opened and closed based on the authenticity and denomination determined by the data.
As a result, the coins conveyed by the conveying device 108 are dropped into a predetermined sorting hole for each denomination.

Next, the coin holding unit 112 will be described.
The coin holding unit 112 has a function of holding the coins sorted by denomination in the sorting unit 110 for each denomination.
In the present embodiment, the coin holding unit 110 is arranged with a coin hopper 310 that pays out coins one by one by a rotating disk (not shown) below the sorting unit 110 for each denomination to the upper sorting unit 250 and the lower sorting unit 252. It is configured by arranging in two rows relative to each other.
Each coin hopper is displayed with a symbol 310 added to the symbol for each denomination.

Next, the dispensing device 114 will be described.
The dispensing device 114 has a function of conveying coins paid out from the coin hopper for each denomination to the dispensing tray 320.
In the present embodiment, the dispensing device 114 is a flat belt 330 disposed between two rows of coin hopper rows.
The flat belt 330 is selectively driven by the electric motor 332 so that the upper surface moves toward the dispensing tray 320.
Coins conveyed by the flat belt 330 are supplied into the dispensing tray 320.

Next, the operation of this embodiment will be described.
When coins of multiple denominations are thrown into the slot 120, the thrown coins fall on the deposit flat belt 122.
Thereby, since the optical axis of the photoelectric sensor 128 is blocked by the inserted coin, a deposit detection signal is output, and the motor 126 is rotated by the deposit detection signal.
Accordingly, since the upper surface of the deposit flat belt 122 moves toward the separation / delivery device 104, the coin falls from the end of the deposit flat belt 122 and falls into the holding bowl 132 of the separation / delivery device 104.

When coins are stacked and conveyed, the crushing roller 124 is reversed so that the lower surface of the roller 124 moves in the opposite direction to the upper surface of the deposit flat belt 122, so that the accumulated coins are advanced by the crushing roller 124. Stopped and dropped.
The dropped coins are again conveyed to the separation / delivery device 104 in the same manner as described above as the deposit flat belt 122 advances.
When the deposit sensor 128 no longer detects coins, the motor 126 is stopped, and the driving of the deposit flat belt 122 is stopped.

Further, the motor 150 is rotated by the deposit detection signal of the photoelectric sensor 128, and the gear 154 starts rotating at a predetermined speed via the speed reducer 152.
Therefore, the driven gear 158 meshing with the gear 154 is rotated, and the disc 140 is rotated counterclockwise in FIG.
Further, the gear 216 that meshes with the rotation of the driven gear 158 rotates in synchronization with the clockwise direction.
That is, the rotating body 172 rotates in the clockwise direction in FIG. 5 in conjunction with the disc 140 at a transmission ratio of 1: 1.
Further, since the driven gear 238 is rotated by the gear 216, the first sprocket 228 is rotated counterclockwise in FIG.
As a result, the chain 232 is circulated counterclockwise.

Therefore, the coins that fall into the storage bowl 132 are stirred by the plate 146 and the extruded body 148 and can be changed in various postures.
In the process of changing the posture, only one coin is accepted by each receiving unit 138.
That is, one surface of the coin is positioned in the receiving portion 138 in a state where it is in surface contact with the disc 140 and is pushed by a part of the side surface of the plate 146 to move with the rotation of the disc 140.

Immediately after the receiving part 138 passes through the uppermost position, the extruded body 148 pivots counterclockwise and moves in the circumferential direction of the disc 140.
Thereby, the coin located in the receiving part 138 is extruded by the extrusion body 148 to the circumferential direction of a disc.
Immediately after being guided by the receiving body 134, the pushed-out coin is pushed by the pushing lever 184 of the rotating body 172 that rotates in conjunction with the disc 140.

When the amount of coins falling on the storage bowl 132 is a predetermined amount or more, a full signal is output from the full sensor 136.
By this full signal, the motor 126 is stopped even if the photoelectric sensor 128 detects the inserted coin, and the coin is prevented from being excessively inserted into the separation and delivery device 104.
If the coins in the holding bowl 132 are sent out by the rotation of the rotating plate 130, the full signal is not output from the full sensor 136, and the photoelectric sensor 128 is outputting the deposit signal, the motor 126 is restarted, Coins on the belt 122 are supplied to the separation / delivery device 104.

The coin pushed by the pushing lever 184 moves through the movement path 190 while its one surface is in contact with the slide base 170.
At this time, the coin is subjected to a force pushed in the circumferential direction because the pushing portion 206 is at an acute angle with respect to the reference guide 174, and the coin circumferential surface is brought into the linear guide portion 188 of the reference guide 174 by the centrifugal force of the coin itself. Move while being pressed.
In this movement process, first, the upper and lower surfaces of the coin face the upper and lower thickness sensors 164.
At the same time, small-diameter coins such as 1 cent are not opposed, but middle and large-diameter coins such as 50 cents and 2 euro coins are opposed to the upper and lower second diameter sensors 194 at the top of the coins.

The coins to be pushed next face the upper and lower material sensors 162 on the entire upper and lower surfaces, and with a slight delay, face the entire upper surface or one surface of the upper and lower first diameter sensors 192 and the upper and lower third diameter sensors 196.
Accordingly, the output of the coil of the thickness sensor 164 changes under the influence of the thickness of the coin, and the coils of the second diameter sensor 194, the first diameter sensor 192, and the third diameter sensor 196 have a relative area to the coin. The output changes under the influence, and the output of the material sensor 162 changes under the influence of the material of the coin.

Therefore, by comparing the outputs of these sensors 162, 164, 192, 194 and 196 with the reference values, the authenticity and denomination of each coin can be determined.
In particular, since the coin is always guided by the straight guide portion 188 of the reference guide 174, the relative position between the coin and each sensor is the same every time.
In other words, since the sampling data of coins of the same denomination are the same, it is possible to determine with high accuracy.
In addition, since the slide base 170, the rotating body 172, and the upper cover 208 are all made of a non-magnetic material, the magnetic flux generated by the coils of each sensor is not affected by these. The output of is affected.
Accordingly, since the quality of the sampling data is also high, it is possible to make a highly accurate discrimination.

As shown in FIG. 7, immediately after the maximum diameter portion of the coin is opposed to the first diameter sensor 192 and the third diameter sensor 196, a discrimination circuit (not shown) outputs the first denomination signal D1.
When coins are continuously determined, the second denomination signal D2 is output, and thereafter the denomination signal is output in the same manner.
Immediately after the first denomination signal D1 is output, the timing sensor 176 detects one pushing lever 184 and outputs a timing signal T1 of “H”.
The first denomination signal D1 is stored in the control device in association with the timing signal T1.

After facing the material sensor 162, the coin is pushed out by the pushing lever 184 into the movement path 240 of the pushing pin 234 of the transport device 108.
The coin is pushed by the push pin 234 moved by the chain 232 immediately after being pushed out into the moving passage 240.
As a result, the coin is transferred through the movement path 240 while the circumferential surface thereof is guided by the guide rail 226 and is in surface contact with the slide plate 224.

In the middle of the transfer of the coins 240, the first timing sensor 280 and the second timing sensor are based on the denominations stored in association with the timing signals T1, T2,. Based on the timing signals from 282, third timing sensor 284, fourth timing sensor 286 and fifth timing sensor 288, the gate device corresponding to each sorting hole is actuated, and a coin of a predetermined denomination falls into a predetermined sorting hole. Is done.

Specifically, in the case of a false coin, the first timing sensor 280 detects the leading edge of the coin and outputs a reject position signal P1 immediately after the first timing signal T1 is output as shown in FIG. The gate of the reject selection hole 264 is opened for a predetermined time by using the falling signal of the signal P1 as a trigger.
As a result, the false coins moved along the guide rail 226 are not guided by the movable guide 276, and thus fall into the reject sorting hole 264, guided by a chute (not shown), and dropped onto the flat belt 330, and the photoelectric sensor 128 is deposited. It is returned to the withdrawal tray 320 by the flat belt 330 that is activated by the signal and is moving.

When the determined denomination is a 2-cent coin, the gate of the sorting hole 254 is opened for a predetermined time based on the position signal output from the first timing sensor 280.
Accordingly, the 2-cent coin moved while being guided by the guide rail 226 falls into the sorting hole 254, and is then guided by a chute (not shown) and held in the 2-cent hopper 310-2C.

When the determined denomination is a 5-cent coin, the gate of the sorting hole 256 is opened for a predetermined time based on the position signal output from the second timing sensor 282.
Therefore, the 5-cent coin moved while being guided by the guide rail 226 falls into the sorting hole 256, is guided by a chute (not shown), and is held in the 5-cent hopper 310-5C.

When the determined denomination is 1 cent coin, the gate of the sorting hole 266 is opened for a predetermined time based on the position signal output from the second timing sensor 282.
Therefore, the 1-cent coin that is moved while being guided by the guide rail 226 falls into the sorting hole 266, is guided by a chute (not shown), and is held by the 1-cent hopper 310-1C.

When the determined denomination is a 10 cent coin, the gate of the sorting hole 258 is opened for a predetermined time based on the position signal output from the third timing sensor 284.
Therefore, the 10-cent coin moved while being guided by the guide rail 226 falls into the sorting hole 258, is guided by a chute (not shown), and is held by the 10-cent hopper 310-10C.

When the determined denomination is 2 euro coin, the gate of the sorting hole 268 is opened for a predetermined time based on the position signal output from the third timing sensor 284.
Therefore, the 2 euro coin moved while being guided by the guide rail falls to the sorting hole 268, is guided by a chute (not shown), and is held in the 2 euro hopper 310-2E.

When the determined denomination is a 20 cent coin, the gate of the sorting hole 260 is opened for a predetermined time based on the position signal output from the fourth timing sensor 286.
Therefore, the 20-cent coin moved while being guided by the guide rail 226 falls into the sorting hole 260, is guided by a chute (not shown), and is held in the 20-cent hopper 310-20C.

When the determined denomination is a 50 cent coin, the gate of the sorting hole 270 is opened for a predetermined time based on the position signal output from the fourth timing sensor 286.
Therefore, the 50 cent coin moved while being guided by the guide rail 226 falls into the sorting hole 270, is guided by a chute (not shown), and is held by the 50 cent hopper 310-50C.

When the determined denomination is 1 euro coin, the gate of the sorting hole 272 is opened for a predetermined time based on the position signal output from the fifth timing sensor 288.
Therefore, the 1 euro coin moved while being guided by the guide rail 226 falls into the sorting hole 272, and is then guided by a chute (not shown) and held in the 1 euro hopper 310-1E.

When the coin storage amount of any hopper exceeds a predetermined value, in other words, in the overflow state, the gate of the corresponding sorting hole is not opened.
In other words, since it does not fall into any sorting hole, it falls into the overflow sorting port 262 and is held in the overflow hopper 310-OF.

The detection signal of the overflow arrival sensor 290 is used as a signal for confirming that the coin has reached the overflow hopper 310-OF.
Therefore, the coins inserted into the insertion slot 120 are sorted into a predetermined denomination sorting hole based on the denomination determined by the denomination determination device 106.

When a predetermined number of predetermined denominations are withdrawn, first, the motor 332 drives the upper surface of the flat belt 330 to move toward the withdrawal tray 320.
Next, a predetermined number of coins are paid out from a hopper of a predetermined denomination and sent out to a withdrawal tray 320 by a flat belt 330.
