Description

TECHNICAL FIELD The present invention relates to a coin feeding device for feeding coins one by one and a coin processing device provided with the coin feeding device.

Commonly, circulating currency issued by a nation includes coins of multiple denominations. Coins differ in diameter, thickness, material, and design for each denomination, so that anyone can easily identify the denomination. Since each denomination has different characteristics, it is also possible to identify the denomination by machine. However, it is conceivable that an erroneous identification is made in an exceptional state such as two coins overlapping each other. Therefore, it is necessary to separate the coins one by one, convey them to the identification device, and identify the denomination of each coin.

For example, as a coin feeding device for feeding coins in a storage container one by one, a coin feeding device disclosed in Japanese Patent Application Laid-Open No. 2011-165003 is known.

Such a coin dispensing device has a two-stage process. First, a step of separating and sending out a plurality of coins in the storage container one by one, and then a step of identifying the denomination of the coins that are conveyed one by one. Further, if a step of sorting the identified coins by denomination and storing them is provided in the subsequent stage of the coin sending device, the coin processing device can be obtained.

This coin delivery device has a disc arranged obliquely. A storage container for temporarily storing coins is arranged in the lower portion of the disc. Rotate the disc and pick up the coins in the storage container one by one. The disk is provided with a recess for receiving one coin. By passing the disc through the storage container, only one coin accumulated in the storage container enters the recess and is conveyed. The upper part of the disk is equipped with a mechanism for transferring coins to the next process. The coins held in the recesses are conveyed above the disk and passed one by one to the next process. In the next step, multiple sensors are arranged to detect characteristics such as coin size and material. A sensor detects the characteristics of the coin and identifies the denomination of the coin. Thus, the coin sending device can take out one coin from a plurality of coins, send the coins one by one to the next process, and identify the denomination of the coin.

Also, in the coin processing device, after identification, the coin is transferred to the next process. In the next process, the coins are conveyed by the belt in a state where they are sorted one by one. A slide is arranged for each denomination in the middle of the transport path. Each slide is connected to a coin hopper arranged for each denomination. Each slide also has a mechanism for selectively transferring coins from the belt to the slide. As a result, the coin whose denomination has been identified is dropped onto the slide of the corresponding denomination during transportation. The coins dropped on the slide slide down to the storage container of the coin hopper by denomination and are stored therein.

The coin hopper can discharge a desired number of coins. An example of a coin processing device is an automatic change machine. The automatic change machine calculates the denomination and number of coins to be discharged according to the amount of change, controls the coin hopper corresponding to each denomination, and discharges the required number of coins.

JP 2011-165003 A

A coin processing apparatus must separate and identify all coins one by one from a container in which a plurality of coins with different diameters and thicknesses for different denominations are stored, and send them to the next process.

In addition, users of coin processing devices such as automatic change dispensers and money changers desire to shorten the waiting time from the start to the end of processing. Therefore, a coin sending device, a coin processing device, and a device capable of handling a plurality of coins at once are desired.

For example, when the coins stored in the storage container are separated and identified one by one, the processing speed can be improved by increasing the number of revolutions of the disk that separates the coins.

On the other hand, however, when a coin hits a disk or wheel that rotates at high speed, it may spring up vigorously and move in an unexpected direction. If the passing position or speed of the coin is out of the expected range in the area where the coin's features are detected, the coin's features cannot be detected accurately, resulting in erroneous judgments and malfunctions.

The present invention provides a coin feeding device and a coin processing device capable of suitably controlling the movement of a coin and conveying it at a suitable position and at a suitable moving speed even within the coin detection range even if the processing speed is improved.

The coin delivery device of the present invention comprises a wheel for receiving the coins delivered one by one from a storage container for storing coins and for transporting the coins; a sensor for identifying the denomination of the coin; and a guide section for guiding the coin pushed by the wheel to move on the surface of the base to an identification section where the sensor is arranged. , further comprising a guide member for guiding the coin moving on the surface of the base by the wheel toward the guide portion, the guide member provided facing the surface of the base. The coin is pushed toward the base by the thin plate and pushed by the wheel to move toward the guide section . The thin plate is inclined with respect to the surface of the base so that the distance from the thin plate is narrower on the side closer to the guide portion than on the side farther from the guide portion; a portion of the lamella is in contact; or the lamella is arranged at an angle to the surface of the base such that the side of the wheel in the direction of rotation approaches the surface of the base; A pin for changing the course of the coin that has passed through the unit to the next process is arranged in the moving range of the wheel of the base, and the wheel has a recess opening toward the base, and the wheel is When rotating, the pin passes through the recess so that the wheel rotates without coming into contact with the pin, and the coin comes into contact with the pin to change course and move by the wheel. is characterized by canceling the

A coin processing apparatus according to the present invention comprises the above-described coin sending device, storage means for storing the coins whose denominations have been identified for each denomination, discharge means for discharging the coins one by one from the storage means, characterized by having

According to the present invention, even if a plurality of coins are inserted from the coin slot at the same time, the coins can be preferably separated one by one and the denominations of the coins can be identified.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Each drawing is merely a schematic representation to the extent that the present invention can be fully understood. Accordingly, the present invention is not limited to the illustrated examples only. Moreover, in each figure, the same code|symbol is attached|subjected about a common component and a similar component, and those overlapping description is abbreviate|omitted.

First, the coin processing device will be described with reference to FIG. FIG. 1 is a perspective view of a coin processing device. Commonly used coins consist of multiple denominations. Coins have different elements such as size, material, and design for each denomination. The coin processing device can identify coins and sort them by denomination for storage. Also, the stored coins can be paid out.

The coin processing device 1 inserts coins from the slot 3, identifies the denomination inside, and stores the coins by denomination. Also, the stored coins are ejected from the ejection port 6 provided on the bottom side of the coin processing device 1 as needed. The slot 3 has a width that allows at least two coins to be stacked in the thickness direction and inserted at the same time. That is, the slot 3, which is a coin slot, can be inserted into the slot 3 in a state in which two or more coins are piled up in the thickness direction. It is preferable that there is an opening into which about 2 to 10 coins can be piled up. This is because if a large number of coins are inserted at once, the user only needs to insert coins once, which is highly convenient. On the other hand, the possibility of contamination by foreign matter increases.

The coin processing device 1 is covered with an exterior 2 . A slot 3 for inserting coins is provided on one surface of the coin processing device 1 . A discharge port 6 is provided on the lower surface of the coin processing device 1 where the insertion port 3 is provided. In addition, the coin processing device 1 is provided with a first maintenance door 4 and a second maintenance door 5, so that internal mechanisms and the like can be maintained without removing the exterior 2. FIG. Each door is provided with a lock device, and maintenance can be performed by a person with a key.

Next, the internal structure of the coin processing device 1 will be described with reference to FIGS. 2 and 3. FIG. FIG. 2 is a perspective view of the coin processing device with the exterior removed and viewed from the first direction. FIG. 3 is a perspective view of the coin processing device with the exterior removed and viewed from the second direction.

The coin processing device 1 includes a storage container 13 that temporarily stores coins inserted from the slot 3 . A lower portion of the storage container 13 is opened at a portion corresponding to the disk of the separating portion 11 . Coins are separated one by one by the disk and sent to the discriminating section 12 . In the discriminating section 12, the coins are sent one by one by the wheel 14.例文帳に追加The denomination of the coins sent one by one is identified when passing through the identification sensor section 20 . The identification sensor unit 20 has a plurality of sensors and detects features such as the material and size of the coin. The detected information is acquired by control means (not shown), and the denomination and authenticity are determined.

In the transfer section 15, the coins are transferred from the identification section 12 to the sorting section of the next process. In the sorting section, a sorting belt 21 is arranged movably along rails 23 . A plurality of conveying pins 22 are provided on the sorting belt 21 . The conveying pin 22 moves along with the movement of the sorting belt 21 , pushes the coins 10 one by one, and moves them along the rail 23 . A single coin 10 is conveyed between the conveying pins 22 .

The coin 10 is fed out from the identifying section 12 so that only one coin 10 is inserted between the conveying pins 22.例文帳に追加The wheel 14 of the identification unit 12 and the distribution belt 21 rotate so that the delivery timing matches. Bars 24 are provided on slides 25 provided corresponding to denominations. Whether the coin 10 is dropped onto the slide 25 or moved along the rail 23 is controlled depending on the state of the bar 24 . Movement of the bar 24 is controlled by control means (not shown).

When the coin 10 reaches the position of the slide 25 that matches the denomination, the state of the bar 24 is changed and the coin 10 falls onto the slide 25.例文帳に追加The coin 10 dropped onto the slide 25 is guided by the passage 26 and stored in the coin hopper 30 of the corresponding denomination. In this example, four coin hoppers 30 are arranged side by side.

The coin hopper 30 has an opening at the top, and the coin 10 guided by the passage 26 is stored in the coin storage container of the coin hopper 30. - 特許庁The coin storage container can also be said to be storage means for storing coins. The coin hopper 30 discharges the coins 10 contained in the coin storage container one by one from the payout portion 31 onto the payout belt 28 . The payout belt 28 is a free belt and is rotated to carry the coin 10 to the outlet 6. - 特許庁The coin hopper 30 can also be said to be a discharging means for discharging the stored coins 10 one by one.

The right end slide 25 in the drawing is connected to the reject passage 27 . The coin 10 dropped onto the slide 25 is discharged to the discharge port 6 through the reject passage 27. - 特許庁The slide 25 at the right end is dropped based on the identification result of the identification unit 12, and the coin judged not to be a depositable coin is dropped. For example, coins without coin hoppers 30 of corresponding denominations, counterfeits, and medals that are not coins.

The cutout portion 19 is a cutout provided below the insertion port 3 of the coin processing device 1 and forms the discharge port 6 together with the exterior 2 .

A magnet 29 is provided in the passage between the inlet 3 and the storage container 13 . This magnet attracts objects containing ferromagnetic components such as iron. As a result, it is possible to prevent foreign matter including iron, such as screws, from entering the storage container 13 .

Also, the opening/closing portion for removing foreign matter includes a first flap 17 and a second flap 16 . The first flap 17 and the second flap 16 move away from each other and open to drop the foreign matter inside to the foreign matter guide portion 18 . Foreign matter is discharged to the discharge port 6 .

The payout belt 28 carries the coins 10 discharged from the coin hopper 30 and rotates in the direction of the discharge port 6 . Then, the coin 10 falls from the end of the payout belt 28 to the discharge port 6. - 特許庁

Driving parts such as the separation unit 11, the identification unit 12, the sensor of the identification sensor unit 20, the sorting unit, the coin hopper, the payout belt, and the opening/closing unit are controlled by control means (not shown). A separation unit 11 separates the coins 10 one by one and sends them to an identification unit 12.例文帳に追加The identification unit 12 determines the denomination of each coin 10 and sends it to the sorting unit. In the sorting section, the coins 10 are conveyed by the sorting belt 21 . When the coin 10 reaches the slide 25 of the corresponding denomination during transportation, the bar 24 is driven and dropped onto the slide 25 . The dropped coins 10 are stored in the coin hopper 30 by denomination. The coin hopper 30 discharges the required number of coins 10 onto the payout belt 28 by the control means, drives the payout belt 28 , and discharges the coins from the discharge port 6 .

When there is foreign matter, the first flap 17 and the second flap 16 are driven to drop the foreign matter from the storage container 13 to the foreign matter guide portion 18 . Foreign matter is discharged to the discharge port 6 . At this time, the foreign matter attracted by the magnet 29 falls to the foreign matter guide portion 18 as the distance between the foreign matter and the magnet 29 increases due to the movement of the second flap 16 .

Next, movement of the coin 10 between the separating section 11 and the identifying section 12 will be described. FIG. 4 is a diagram for explaining an overview of coin movement of the coin sending device.

The separation section 11 and the identification section 12 are arranged in the frame 41 . The disc 44 rotates around a disc rotating shaft 45 . Wheel 14 rotates about wheel rotation axis 48 . The wheel 14 has four arms, and each arm pushes and conveys the coin 10 . The disk 44 has four openings 46, and the coins 10 are put into the openings 46 and conveyed. A wall portion 40 is provided outside the disk 44 and the wheel 14 to prevent the coin 10 from moving outward.

The disk rotating shaft 45 and the wheel rotating shaft 48 are rotated by a motor (not shown). A gear train (not shown) connects the motor and the disk rotating shaft 45 . Further, the motor and the wheel rotating shaft 48 are connected by a train wheel (not shown). The motor and gear train constitute a drive that rotates the disk 44 and wheel 14 .

The holding base 43 of the separating section 11 forms a flat bottom surface on which the coin 10 is placed and held. The receiving base 47 of the identification portion 12 forms a flat bottom surface that holds the coin 10 . A wheel 14 is rotatably arranged to face the receiving base 47 . The holding base 43 and the receiving base 47 are arranged without a step, and can be brought into contact with the obverse or reverse side of the coin 10 and slidably moved.

The identification sensor section 20 is divided into a part of the receiving base 47 and a part facing it so as to sandwich the coin 10 .

The disk 44 is provided with a plurality of equiangular openings 46, four here. Coins 10 held by openings 46 are passed between the arms of corresponding wheels 14 . Here, an example in which the disc 44 is provided with the opening 46 is described, but a recess opening on the outer peripheral side or a mechanism for holding the coin 10 by providing a protrusion on the disc may be used.

A pin is provided at a portion for transferring the coin 10 from the disk 44 to the wheel 14. - 特許庁This pin allows the coin 10 moved by the rotation of the disk 44 to be turned in the direction of the wheel 14 . The direction of rotation of the disk 44 and the wheel 14 are opposite to each other, and they rotate together.

The identification sensor section 20 is provided with a guide section 42 along which the coin 10 is linearly moved. The guide section 42 guides the coin 10 to the identification sensor section 20 . Coins come in various sizes and shapes, and in order to detect and compare their characteristics, it is desirable to measure the characteristics of the coin 10 under constant conditions. In order to detect the features of the coin 10 under certain conditions, it is desirable to detect them at as equal positions as possible. Therefore, the coin 10 is moved along the guide portion 42 . The side surface of the coin 10 is brought into contact with the guide portion 42 and moved. While the coin 10 is moving along the guide portion 42, various detections are performed in the area of the identification sensor portion 20, and information on which the denomination is determined is acquired by a control means (not shown). The denomination is determined by the control means based on the acquired information.

The receiving base 47 is provided so as to be inclined with respect to the vertical direction. For example, it is inclined at an angle of 30 to 60 degrees, in this example 45 degrees. In FIG. 4, when the right direction of the paper surface is the X direction and the upward direction is the Y direction, the surface of the guide portion 42 that guides the coin 10 is inclined in the Y direction as it goes in the -X direction. . On the paper surface, the coin 10 is linearly guided in the upper left direction by the guide portion 42 . Gravity acts on the coin 10 in the depth direction and downward direction (-Y direction) of the paper surface, and the coin 10 slides on the receiving base 47 .

After being detected by the identification sensor unit 20 , the coin 10 is pushed by the wheel 14 to move and passed between the conveying pins 22 of the sorting belt 21 . After that, the coin 10 moves along the rail 23 while being pushed by the transport pin 22 .

Like the receiving base 47, the holding base 43 is arranged so as to be inclined with respect to the vertical direction. The holding base 43 is higher on the wheel 14 side and lower on the opposite side. A first flap 17 is provided on part of the lower side of the holding base 43 . The first flap 17 normally slides the coin 10 like the holding base 43 . A rotation shaft is arranged along the center side edge of the disk 44 of the first flap 17 . By rotating the first flap 17 in the rotating direction of the rotating shaft, the opening of the holding base 43 can be opened and closed. When removing the foreign matter, the first flap 17 is opened in the direction away from the disc 44 . Foreign matter in the opening 46 can be dropped into the foreign matter guide portion 18 by opening the first flap.

When the disk 44 and the wheel 14 rotate slowly, the coin 10 moves along the guide portion 42 while being pushed by the wheel 14 . However, as the speed of the disk 44 and the wheel 14 increases, when the wheel 14 and the coin 10 come into contact, the bounce becomes uncontrollable. For example, like the coin 49 indicated by the dotted line, it bounces around without moving along the guide section 42, and the detection value of the identification sensor section 20 indicates an abnormal value. Also, when the coins 10 are transferred to the next process, there is a problem that the coins cannot be transferred between the transfer pins 22 one by one. In addition, when the coin 10 is transported, the transport pin 22 flips the coin 10 up and moves violently between the transport pins 22, causing a problem that the coin 10 cannot be dropped onto the slide 25. - 特許庁It is necessary to eliminate such problems when conveying at high speed.

Next, the coin sending device will be described with reference to FIG. FIG. 5 is a perspective view of the main parts of the coin feeding device as viewed from above.

The separating unit 11 separates the coins in the storage container 13 one by one and delivers them to the identifying unit 12 . Coins inserted from the slot 3 can drop into a storage container 13 and be stored. A second flap 16 is arranged on a part of the storage container 13, and this part opens and closes. If foreign matter is mixed in, the foreign matter can be removed from the upper and lower sides of the disk 44 by opening the second flap 16 and the first flap 17 in directions away from each other.

The cover 32 is a cover that covers the upper portion of the wheel 14, and can prevent coins from flying out, and can protect the driving portion from foreign matter such as dust.

A magnet 29 is placed in the reservoir 13 between the coin slot 3 and the disc 44 . The magnet 29 attracts foreign matter including ferromagnetic substances such as iron. Foreign matter is prevented from entering the storage container 13. - 特許庁

Next, movement of coins in the separating section 11 and the identifying section 12 will be described. FIG. 6 is a first diagram for explaining the movement of coins of the coin sending device.

A lamella 50 is provided to prevent the coin 10 from being struck and bounced by the wheel 14 as it travels over the receiving base 47 . The thin plate 50 is a flexible resin sheet. For example, holding one end of the thin plate 50 and pressing the other end against a flat surface bends the thin plate 50 . The thin plate 50 is fixed to the base 52 by the fixing portion 51 . The thin plate 50 is inclined with respect to the receiving base 47 . The distance of the lamina 50 to the receiving base 47 varies from place to place. The thin plate 50 is arranged so that the distance to the receiving base 47 is shorter on the side closer to the guide portion 42 than on the farther side. That is, the gap formed by the thin plate 50 and the receiving base 47 is arranged so that the guide portion 42 side is narrower than the rotation center side of the wheel 14 . When the guide portion 42 side of the thin plate 50 is between the arms of the wheel 14 , the guide portion 42 side of the thin plate 50 contacts the receiving base 47 and the opposite side rides on the wheel 14 . In addition, the edge of the thin plate 50 including the front end on the center side of the wheel 14 always rides on the wheel 14 . For example, when the wheel 14 is reversed for maintenance work or the like, since the tip of the thin plate 50 is above the wheel 14, it can be prevented from entering below the wheel 14. - 特許庁Also, the spacing between the thin plate 50 and the receiving base 47 is arranged differently depending on the location. By changing this interval, the pressing force to the coin 10 can be changed. By changing the pressing force applied to the coin 10 depending on the location, the coin 10 can be easily moved in the direction of the guide portion 42.例文帳に追加The thin plate 50 can also be said to be a guide member that guides the coin 10 .

Also, a control pin 53 is provided so that the coin 10 is transferred between the transfer pins 22 . The control pin 53 prevents the coin 10 from being carried by the wheel 14.例文帳に追加That is, when the coin 10 comes into contact with the control pin 53, the coin 10 changes its course, is released from movement by the wheel 14, and is guided to the next process. The wheel 14 is provided with a concave portion which is open on the side of the receiving base 47 at a portion corresponding to the control pin 53 . The recess in the rotating wheel 14 causes the wheel 14 to rotate without contacting the control pin 53 . This is nothing other than that the control pin 53 is provided in the moving range of the wheel 14 of the receiving base 47 . The coins 10 are guided by the control pins 53 to the sorting section, which is the next step. The control pin 53 is arranged at a portion facing the rotating wheel 14 . Also, the control pin 53 is arranged closer to the center of the wheel 14 so that the smallest coin to be used is not caught between the control pin 53 and the wheel 14 .

The base 52 faces the receiving base 47 and is spaced apart. Wheel 14 can pass between base 52 and receiving base 47 without contact. When the wheel 14 comes into contact with the coin 10, even if the coin 10 bounces, the movement in the thickness direction is restricted by the base 52. - 特許庁

The thin plate 50 abuts the coin 10 and the wheel 14 . When the coin 10 passes between the thin plate 50 and the receiving base 47, the coin 10 moves toward the guide portion 42. - 特許庁Also, the coin 10 is pushed by the arm of the wheel 14 to move. It moves along the guide portion 42 at the rotational speed of the wheel 14, that is, under constant conditions. As a result, the coin 10 can be preferably detected by the identification sensor section 20 .

FIG. 6 shows a state in which the coin 10 is about to be delivered from the disk 44 to the wheel 14. As shown in FIG. It is just before the wheel 14 comes into contact with the coin 10 . The subsequent state will be described with reference to FIG. FIG. 7 is a second diagram for explaining the movement of coins of the coin sending device.

The state in which the wheel 14 contacts the coin 10 is the coin 54 indicated by the dashed line. The coin 54 is in strong contact with the wheel 14 and hits the side wall and the base 52 while moving toward the center of the wheel 14 instead of toward the guide portion 42 as shown by the dashed line of the coin 55 . showing. Even in such a case, the coin 55 indicated by the dashed line enters under the thin plate 50 and its movement is restricted. That is, the thin plate 50 reduces the moving speed of the coin 55 indicated by the dashed line. sometimes stop. The thin plate 50 is arranged with a wider interval to the receiving base 47 on the fixing portion 51 side than on the rotating direction side of the wheel 14 . Since the receiving base 47 is arranged to be inclined with respect to the vertical direction, downward force is always applied to the coin 55, causing the coin 55 to slide down. The coin 10 enters the gap between the thin plate 50 and the receiving base 47 and is restrained from moving, and is moved toward the guide portion 42 by gravity and the rotational force of the wheel 14 .

Also, the coin 56 indicated by the dashed line, which has been conveyed earlier, is pushed by the wheel 14 and comes into contact with the control pin 53, is guided in the direction of the coin 57 indicated by the solid line, that is, toward the sorting section, and is conveyed. It is passed between pins 22 .

A continuation of the state shown in FIG. 7 will be described with reference to FIG. FIG. 8 is a third diagram for explaining the movement of coins of the coin sending device.

A coin 58 indicated by a dashed line is restrained in its moving direction and moving speed by the thin plate 50, pushed by the wheel 14, and guided toward the guide portion 42. As shown in FIG. Then, it moves in the area of the identification sensor section 20 while being in contact with the guide section 42 . As a result, the coin 58 moves along the guide portion 42 at a speed corresponding to the angular speed of the wheel 14 . In other words, the sensor can detect different characteristics individually while moving from a predetermined position at a predetermined speed.

A continuation of the state shown in FIG. 8 will be described with reference to FIG. FIG. 9 is a fourth diagram for explaining the movement of coins of the coin sending device.

The coin 59 guided toward the guide portion 42 by the thin plate 50 and the wheel 14 moves while contacting the guide portion 42 . The thin plate 50 covers a range of about 1/2 of the moving distance of the coin 59 above the area of the identification sensor section 20 . The thin plate 50 can be used to suppress ricocheting caused by contact between the wheel 14 and the coin at an early stage. At least before the coin enters the area of the identification sensor portion 20, it is preferable that the thin plate 50 starts restraining the movement. Also in the area of the identification sensor section 20, it is preferable that the thin plate 50 suppresses the movement of the coin. Further, even if the movement of the coin is not restricted in the entire area of the identification sensor section 20, once the movement of the coin is restricted in a part of the area at the beginning, the coin can be moved together with the wheel 14. .

The thin plate 50 is provided in a direction in which the extension line of the edge 60 on the tip side intersects the guide portion 42 . The first corner 63 of the thin plate 50 is located ahead of the second corner 62 in the coin traveling direction. Also, the first corner 63 is positioned to abut against the wheel 14 . The second corner 62 is spaced from the guide portion 42 and is positioned to substantially overlap the end of the wheel 14 . When the coin 59 contacts the thin plate 50 , the side of the coin 59 farther from the guide portion 42 contacts the thin plate 50 for a longer period of time than the side closer to the guide portion 42 . In addition, since the edge 60 on the tip side of the thin plate 50 is arranged so as to be inclined with respect to the guide portion 42, when the wheel 14 is reversely rotated during maintenance or the like, the edge 60 on the tip side will not move toward the wheel 14. can be prevented from entering under the When the wheel 14 is reversely rotated, the wheel 14 moves while changing the contact position with the edge 60 on the leading end side. At this time, the abutment position moves from the center side of the wheel 14 of the edge 60 on the tip side toward the guide portion 42 side. The wheel 14 is provided with four arms, and the sides between them are formed by a combination of curved surfaces arranged roughly in an arc. Depending on the angle of arrangement, the tip of the arm of the wheel 14 may come into contact with the central portion of the edge 60 on the tip side first. When this happens, the thin plate 50 may get stuck under the wheel 14 . In order to prevent this, thin plates 50 are arranged corresponding to the shape of the wheel 14 .

The proximal side 61 of the lamina 50 is positioned further from the receiving base 47 than the distal edge 60 . As the coin progresses, the pressing force is gradually increased to control the direction of movement. Between the arms of the wheel 14, the thin plate 50 is arranged such that a portion of the tip side of the thin plate 50 is in contact with the receiving base 47 if the coin 10 is not present.

The thin plate 50 is arranged so that the second corner 62 side hits the coin more strongly than the first corner 63 side. Also, the thin plate 50 is a sheet made of resin and is flexible. The thin plate 50 bends when it comes into contact with the wheel 14 or the coin. Also, the surface of the thin plate 50 is flat so that the coin can slide easily.

The thickness of the wheel 14 is formed thicker than the thickness of the coin. Assuming that the receiving base 47 of the wheel 14 is the back side and the opposite side thereof is the front side, the side surface of the portion of the wheel 14 that pushes the coin is an inclined surface that gradually protrudes in the advancing direction from the back side to the front side. As a result, the wheel 14 can slide the coin obliquely while pressing it toward the receiving base 47 .

The coin is conveyed by the wheel 14 while being given a different pressing force depending on the location in the thickness direction of the thin plate 50 , and finally moves while being in contact with the guide portion 42 . The coin will slide or roll. Coins with different diameters are used, but coins of any diameter can be restrained from moving by the thin plate 50 and can be conveyed favorably.

Next, the control of the coin moving direction by the thin plate 50 will be described. FIG. 10 is a schematic diagram for explaining the operation of the thin plate and the operation of the coin. The thin plate that suppresses the movement of the coin will be described as a rectangular shape so as to facilitate the description.

A description will be given of the states at a plurality of contact positions between the wheel and the coin. At the first contact position 70, the second contact position 71, the third contact position 72, and the fourth contact position 73, the coin moves to the first coin position 75 and the second coin position 73, respectively. Position 76 , third coin position 77 and fourth coin position 78 . The coin is restrained from moving by the thin plate 50 and guided toward the guide portion 42 . Then, in the section 74, the coin moves while being in contact with the guide portion 42. As shown in FIG. A section 74 is a section in which the feature of the coin is detected by the sensor. At least a part of the section 74 is configured to cover a part of the thin plate 50 . Once the coin moves along the guide portion 42 while being restrained by the thin plate 50, it is also affected by gravity and moves along the guide portion 42 as it is.

The section 74 is a section shorter than the total length of the guide portion 42 . In other words, the identification sensor section 20 is arranged in a part of the section guided by the guide section 42 . Also, at both ends of the section 74, dashed-dotted lines perpendicular to the guide portion 42 are shown along the receiving base. At least the center of rotation of the wheel is included in the area sandwiched by the dashed-dotted lines. By arranging in this way, the section 74 includes a portion where the tangential direction of the track of the tip of the wheel is parallel to the edge of the guide portion 42 . As a result, the coin can be moved along the guide portion 42 by the wheel at the farthest position from the center of rotation of the wheel. The speed can be kept as constant as possible. In the section 74, the coin can be moved at a speed based on the position of the guide portion 42 and the rotational speed of the wheel.

At the first coin position 75 , the tip of the coin abuts the base end side 61 of the thin plate 50 to restrain the movement of the coin 10 . In that state, the coin is pushed by the wheel 14 and moves. In the second coin position 76 it is pushed by the wheel 14 while being constrained by the lamella 50 . At this time, the gap between the thin plate 50 and the receiving base 47 becomes narrower as it progresses, thereby suppressing the violent movement of the coins. The coin can be easily controlled by the wheel 14, and the coin can be easily moved in the arrow 79 direction. The more the coin is pushed deeper into the thin plate 50, the more force acts in the direction of the arrow 79. The distance between the first corner 63 side, the second corner 62 side, the base end side 61, and the tip end side edge 60 of the thin plate 50 with respect to the receiving base 47 allows the coin pushed by the wheel 14 to move toward the guide portion 42. is preferably set as follows.

Furthermore, when a coin is pushed by the wheel 14, it abuts against the guide portion 42 as in the third coin position 77. As shown in FIG. After that, even if the coin is separated from the thin plate 50 , it moves toward the fourth coin position 78 while being in contact with the guide portion 42 .

FIG. 11 is a schematic diagram illustrating another example of the thin plate. The thin plate 81 is provided with a plurality of projections 82 on the side of the receiving base 47 . The convex portion 82 consists of a gentle slope that gradually rises in the direction of the guide portion 42 and a steep slope that lowers. The coin 10 is moved by the wheel 14 while pressing the thin plate 81 toward the receiving base 47 side. As the distance from the guide portion 42 increases, the pressing force against the coin 10 increases. The coin 10 can easily move in the direction of the guide portion 42 , that is, in the direction indicated by the arrow 83 , due to the step of the convex portion 82 , but is difficult to move in the opposite direction.

Further, by making the side farther from the guide portion 42 stronger as indicated by arrow 84 and weakening the side closer to the guide portion 42 as indicated by arrow 85 , it becomes easier to move in the direction indicated by arrow 83 . This is the same even when there is no convex portion.

By arranging the thin plate 81 so as to be inclined with respect to the receiving base 47, the pressing force of the thin plate 81 to the coin 10 is made different depending on the location, thereby controlling the movement of the coin 10.例文帳に追加Further, the movement of the coin 10 may be controlled by providing a guiding means such as a protrusion 82, a groove, or a key-like object on the surface. Alternatively, the pressing force may be controlled by gradually or stepwise changing the thickness of the thin plate 81 toward the guide portion 42 side. Even if these are used in combination, it is possible to control the coin so that it is easy to move in the direction of the arrow 83, but difficult to move in the opposite direction.
