Description

  The present invention relates to a coin deposit / withdrawal mechanism incorporated in an automatic cash transaction apparatus, a ticket vending machine, or the like, and more particularly to a coin deposit / withdrawal mechanism and an automatic transaction machine used when batch coin processing is required.

  As a structural example of the coin deposit / withdrawal mechanism, the coin receiving port is provided with a concave rotating drum, and when a driving load is applied to the driving gear when this rotational drive is applied, the lever provided on the rotating spindle is moved to the coin receiving port. A load to push the rotating drum back in the counter-rotating direction is applied, and the rotating drum is vibrated by the movement to push it back, and the coins in the rotating drum are vibrated. There has been proposed a coin processing device that reliably discharges coins that may remain due to this vibration (see, for example, Patent Document 1).

  In addition, a vibrating means is formed that vibrates in conjunction with opening and closing of the discharge opening shutter that opens and closes the discharge opening, and the vibration is applied to the coins in the replenishment coin storage portion so that the coins slide down. Yes. Thus, a circulation type coin depositing / dispensing machine has been proposed in which the coins in the replenishment coin storage section are inclined downward to the discharge port to prevent the coins from remaining (see, for example, Patent Document 2).

JP 7-320112 A JP 2006-209345 A

  These are provided with a deposit / withdrawal port that allows a plurality of coins to be inserted at a time and a collective coin process to dispense a plurality of coins at a time. The deposit / withdrawal port has a semicircular tray that is suitable for batch-collecting a plurality of coins on the inner bottom surface. Then, a plurality of coins inserted into the deposit / withdrawal port and a plurality of coins to be dispensed are collected on the bottom surface of the tray, and the presence or absence of coins is detected by the detection means in a state where these coins are collected on the bottom surface of the recess of the tray. It has the composition to do. Thereby, the remaining coins remaining due to poor coin uptake during the deposit process or the coins that the end user forgot to collect during the withdrawal process are detected.

  However, collecting the coins on the bottom of the saucer is expected to cause the coins to slide down the surface of the saucer due to its own weight.If the inclination angle of the saucer is slow or the surface of the saucer is stained with coin powder, friction force If it grows, the coin may not slide down. In addition, when a scratched coin, a deformed coin, a wet coin, or the like is inserted, the frictional force changes with the surface of the tray and may not slide down.

  For this reason, although it is the structure which vibrates a saucer or strikes the saucer itself and makes a coin slide down, in order to vibrate the whole saucer, the vibration mechanism itself became a complicated structure and was expensive. This type of vibration generating structure vibrates a fixed object that is hard to vibrate from the beginning, so depending on the degree of contact, it may give a large impact, generate excessive strong vibration and high noise, or contact that only gives a slight impact. It sometimes caused defects.

  Therefore, it is necessary to set the positional relationship between the side to be vibrated and the side to which vibration is applied with high accuracy. For this reason, position adjustment according to the dimensional error for each device is required when setting vibration application. Position adjustment was difficult and skill was required. For example, it may be possible to strike a rotating drum or a saucer that is a vibration object by rotating a rotating body having an uneven surface on the outer circumference or an eccentric rotating body. Becomes difficult. In particular, when the rotating body stops, depending on the stop position, the outer peripheral surface convex portion of the rotating body may stop rotating at a position where it is in strong contact with the opposing vibrating object, in which case the rotational resistance increases. There is a risk of non-rotating.

  In addition, when setting is changed to a vibration amount according to a denomination coin with a different weight such as a 1-yen coin or a 500-yen coin, a high-accuracy position adjustment is required each time, and a desired vibration amount is required. It has a problem that it cannot be switched easily.

  Therefore, the present invention provides a highly reliable coin deposit / withdrawal mechanism and automatic transaction machine that can simplify the vibration imparting structure and can efficiently transmit the optimum vibration to the coins by the contact action of the impeller that expands and contracts. With the goal.

  The present invention includes a concave holding space for temporarily holding a deposit coin inserted from a deposit / withdrawal port and a withdrawal coin to be paid out from the deposit / withdrawal port, and a bottom surface through which the holding space and the inside of the apparatus below the holding space are passed. A concave holding wall provided with an opening, and a receiving tray that moves to a closed position that closes a bottom opening of the concave holding wall and a retreat position that retreats from the closed position and opens the bottom opening, When the tray is moved to the closed position, the coin is prevented from falling from within the holding space, and when the tray is moved to the retracted position, the coin in the holding space is moved to the bottom opening. A coin depositing / withdrawing mechanism that is dropped from the inside of the apparatus and taken into the apparatus, and is formed independently on a part of the concave holding wall, and is provided on the coin non-contact surface side of the independent holding wall. The one holding wall is supported in a freely swinging manner by the portion. A rotating shaft is installed at a position facing the moving wall and the oscillating wall. The rotating shaft is provided on the rotating shaft, and is substantially from a state in which the rotating shaft contracts around the rotating shaft by a centrifugal force generated by the rotation of the rotating shaft. An impeller having one or more flexible wings extending in a radial state; and a drive mechanism for rotating the impeller to rotate the impeller, wherein the swinging of the impeller while the tip of the impeller is rotating The impeller is arranged at a position where the wall is hit intermittently.

  According to the present invention, the structure for imparting optimal vibration to the coin is simplified to reduce the cost, and by using the impeller which expands and contracts, the vibration is efficiently transmitted to the coin, and the coin is reliably transmitted to the bottom surface of the tray. It is possible to provide a highly reliable coin deposit / withdrawal mechanism and automatic transaction machine that can be slid down.

  An embodiment of the present invention will be described below with reference to the drawings.

  The drawings show a coin deposit / withdrawal mechanism that is configured in an automatic teller machine (ATM) that is installed in a financial institution such as a bank and performs deposit transactions and withdrawal transactions.

  FIG. 1 shows a schematic perspective view of an ATM. This ATM is a main control for controlling various transactions and processing of the main body 1, the bill depositing / dispensing mechanism 10, the coin depositing / dispensing mechanism 11, the card statement slip mechanism 12, the passbook mechanism 13, the operation screen 6 and the ATM. Unit 15 and a line connection unit (not shown) that communicates with the host computer of the host.

When a user makes a transaction, a transaction card such as a magnetic card is inserted into the card insertion slot 4 to confirm the identity, and a transaction type such as deposit / withdrawal is selected on the operation screen 6 on which the user performs an input operation.
Here, when the user selects a deposit transaction, a bill to be deposited into the bill insertion slot 2 is inserted. Also, coins to be deposited into the coin slot 3 are inserted.

  The banknote deposit / withdrawal mechanism 10 receives a banknote inserted into the banknote slot 2 and performs identification, counting, and temporary storage. The coin deposit / withdrawal mechanism 11 accepts coins inserted into the coin slot 3 and performs identification, counting, and temporary storage. The user confirms the counting result corresponding to the transaction type of the bill / coin used for the transaction, and confirms the display information displayed on the operation screen 6. When the transaction is established, the banknote deposit / withdrawal mechanism 10 and the coin deposit / withdrawal mechanism 11 store the temporarily stored cash in the storage unit in the apparatus.

  In addition, when the user selects a withdrawal transaction, the main control unit 15 pays out a predetermined number corresponding to the money type of the bill / coin corresponding to the amount requested by the user. 10. Instruct the coin deposit / withdrawal mechanism 11. In the banknote deposit / withdrawal mechanism 10, a predetermined number of sheets instructed from the main control unit 15 are fed out from the banknote storage unit and dispensed to the bill insertion slot 2. Similarly, in the coin deposit / withdrawal mechanism 11, a predetermined number of coins instructed from the main control unit 15 are fed out from the coin storage unit and dispensed to the coin insertion slot 3. In addition, when the user inserts a passbook into the passbook insertion slot 5 in the deposit / withdrawal transaction, the passbook mechanism 13 writes the transaction contents that the user has transacted into the passbook, and then returns it to the user.

Next, the internal structure of the coin deposit / withdrawal mechanism 11 will be described with reference to FIG.
The coin depositing / dispensing mechanism 11 includes a shutter unit 301, an entry / exit unit 302, a feeding unit 303, a determination unit 304, a sorting and conveying unit 305, a temporary holding unit 306, an upper feeding and conveying unit 307, a denomination storing unit 308, and a lower feeding and conveying unit. 309, a coin cassette 310, a batch storage unit 311, a reject transport unit 312, a reject collection box 313, and a coin control unit 71 (see FIG. 7).

  The shutter unit 301 is opened when delivering a coin when a user inserts a coin for a deposit transaction and when a user pays a coin for a withdrawal transaction, and the shutter 301 is closed in other cases to ensure sealing. The entrance / exit section 302 accumulates a plurality of coins in a tray 330 and delivers them to the user. Further, after a plurality of coins input by the user are received by the receiving tray 330, the receiving tray 330 is rotated and dropped to the feeding section 303 directly below the receiving tray 330, and the received coins are collected in a lump. The feeding unit 303 drives the feeding belt 331 with the coins accumulated on the upper surface of the feeding belt 331, separates and feeds the coins one by one by the reverse rotation roller 332, and conveys them to the determination unit 304. The discriminating unit 304 discriminates the authenticity / denomination of the coins conveyed one by one from the feeding unit 303 and conveys them to the sorting and conveying unit 305.

The distribution transport unit 305 distributes coins to the temporary storage unit 306, the denomination storage unit 308, and the reject transport unit 312 according to the determination result of the determination unit 304.
The temporary storage unit 306 temporarily stores the coins determined to be normal by the determination unit 305, and sends them out to the upper feeding / conveying unit 307 as needed, such as a return request.

  The denomination storage unit 308 is a storage unit divided into denominations, and stores coins arranged in these denominations. Further, based on a feeding instruction from the coin control unit 71 (see FIG. 7), a predetermined number of sheets are fed from the denomination storing unit 308 to each denomination and conveyed to the upper feeding and conveying unit 307. In the upper feeding and conveying unit 307, a plurality of coins are separated one by one and conveyed to the inlet / outlet unit 302 for delivery.

  When the coins can no longer be stored in the denomination storage unit 308, the collective storage unit 311 stores the surplus coins in the collective storage unit 311 without dividing the denominations. Further, coins stored in the collective storage unit 311 are sent out to the denomination storage unit 308 via the lower feeding / conveying unit 309 in response to an insufficient number of coins stored in the denomination storage unit 308.

  The coin cassette 310 is attached to and detached from the coin deposit / withdrawal mechanism 11 by an attendant, and is provided for loading coins into the coin deposit / withdrawal mechanism 11. When the coins stored in the coin cassette 310 are stored in the denomination storing unit 308, the coins are guided to the inlet / outlet unit 302 via the lower feeding / conveying unit 309 and the upper feeding / conveying unit 307, and thereby the feeding route serving as a depositing path The information is guided to the denomination storage unit 308 via the unit 303, the determination unit 304, and the distribution transport unit 305. Further, when the clerk collects the coins in the coin deposit / withdrawal mechanism 11, the coins stored in the denomination storage unit 308 and the collective storage unit 311 are stored in the coin cassette 310 and recovered.

  The lower feeding / conveying unit 309 has a function of separating coins fed from the batch storage unit 311 and the coin cassette 310 one by one and conveying them to the upper feeding / conveying unit 307.

  The reject transport unit 312 transports the coin from the sorting transport unit 305 to the upper feed transport unit 307 and returns it to the entrance / exit unit 302 when there is a coin that is determined to be defective or not normal by the determination unit 304. I have to.

Next, main coin processing operations of the coin deposit / withdrawal mechanism 11 will be described.
In the deposit transaction, a plurality of coins mixed with denominations by the user are inserted into the entrance / exit section 302. In the entrance / exit section 302, the tray 330 is rotated and the accumulated coins are dropped to the feeding section 303 below and delivered.

  The feeding unit 303 rotates the feeding belt 331, feeds coins one by one by the reverse rotation roller 332, and conveys all coins to the determination unit 304. The determination unit 304 determines the authenticity / denomination of the coins that have been conveyed one by one, and conveys the determined true coins to the subsequent distribution conveyance unit 305.

  According to the determination result of the determination unit 304, the distribution transfer unit 305 transfers the coins determined to be normal to the temporary holding unit 306, and transfers the coins determined to be not normal to the reject transfer unit 312. The coins that are determined to be not normal pass through the reject transport unit 312 and are transported to the entrance / exit unit 302 by the upper feed transport unit 307 and returned to the user. A processing operation based on such a determination result is performed on all the coins that have been input, and the count result of the accepted appropriate coins is transmitted to the main control unit 15. As a result, the main control unit 15 displays the deposit count result on the operation screen 6, and when the user views the deposit count result and performs a confirmation operation on the operation screen 6, the main control unit 15 executes the storing operation of the deposited coin and executes the storing operation. The deposit transaction ends.

  For the coins temporarily held by the temporary holding unit 306, the coins are collectively delivered to the upper feeding and conveying unit 307, and then coins are fed one by one from the upper feeding and conveying unit 307 to the entrance / exit unit 302. And carry. In the entrance / exit part 302, the coins sent from the upper feeding / conveying part 307 are not collected, but dropped directly below and delivered to the feeding part 303.

  The feeding unit 303 rotates the feeding belt 331 to convey the coins one by one to the determination unit 304, and the determination unit 304 determines the authenticity / denomination, and the normality is determined according to the determination result of the determination unit 304. The sorting and conveying unit 305 distributes the coins to the denomination storing units of the denomination storing unit 308.

  By repeating such processing operations, all the coins temporarily held in the temporary holding unit 306 are stored by dividing them into denominations. When the user performs a return operation on the operation screen 6, the coin of the temporary storage unit 306 is sent to the entrance / exit unit 302 and returned to the user. On the other hand, the coin determined to be not normal passes through the reject transport unit 312 and is transported to the reject collection box 313.

  In the withdrawal transaction, after the withdrawal request amount input by the user on the operation screen 6 is paid out from the denomination storage unit 308 by the number of coins of each denomination corresponding to the amount, and then conveyed to the upper delivery conveyance unit 307 Then, coins are fed one by one from the upper feeding / conveying section 307 to the feeding / outlet section 302. Then, when all the coins of the designated amount are conveyed to the entrance / exit part 302 and accumulated, the shutter part 301 is opened so that the user can take out all the coins, and the coins are accumulated in the entry / exit part 302. Coins can be removed. And it confirms that the coin withdrawn by the user was taken out, and closes the deposit / withdrawal port shutter, thereby completing the one withdrawal transaction.

Next, a coin loading process and a coin collecting process of the coin deposit / withdrawal mechanism 11 will be described.
In the coin storing / dispensing mechanism 11, the coin cassette 310 containing a large number of coins is loaded into the coin depositing / dispensing mechanism 11. Coin feeding is started from the coin cassette 310. First, coins are sent one by one from the coin cassette 310 to the lower feeding / conveying section 309 and transferred, and then one coin is conveyed from the lower feeding / conveying section 309 one by one to the upper upper feeding / conveying section 307.

  The upper feeding / conveying unit 307 conveys the coins sent one by one to the inlet / outlet unit 302, and sends out the coins guided to the inlet / outlet unit 302 from the feeding unit 303 to the determination unit 304.

  The discrimination unit 304 discriminates the authenticity / denomination of the coin, and then conveys the discriminated coin to the sorting conveyance path 305. In the sorting and conveying unit 305, the coins discriminated according to the discrimination result of the discriminating unit 304 at the preceding stage are guided to the denomination storage unit 308 and stored in the denomination to complete the loading.

  Conversely, when collecting coins from the inside of the coin deposit / withdrawal mechanism 11, all coins stored in the denomination storage unit 308 are fed out and transported to the upper feed transport unit 307. The upper feeding / conveying unit 307 feeds coins one by one from this to the inlet / outlet unit 302, conveys the coins from the inlet / outlet unit 302 to the feeding unit 303 and the discriminating unit 304, and then receives the coins from the start end side of the sorting / conveying unit 305. The paper is guided to the reject transport unit 312 and passes from the reject transport unit 312 through a transport path (not shown) to the coin cassette 310 to collect all coins.

Next, the structure of the entrance / exit part 302 of the coin depositing / withdrawing mechanism 11 is demonstrated with reference to FIGS.
3 shows an enlarged view of the main part of the entrance / exit part 302, FIG. 4 shows an enlarged view of the main part showing a state where the impeller 103 of the tray vibration mechanism 340 has stopped rotating, and FIG. FIG. 6 is an enlarged view of a main part showing a state in which the diaphragm 100 is rotated in the clockwise direction, and FIG. 6 is an enlarged view of a main part in a state in which the diaphragm 100 is rotated in the counterclockwise direction under the beating action of the impeller 103. Show.

  The entrance / exit section 302 includes a concave holding wall 320, a tray 330, a coin detection sensor S, and a tray vibration mechanism 340.

  The concave holding wall 320 has a concave shape that allows the user to insert and remove coins from above. The concave holding wall 320 has a large-diameter opening that communicates with a deposit / withdrawal port 301a (see FIG. 2) whose upper side is opened and closed by the shutter unit 301, and deposit coins inserted from the deposit / withdrawal port 301a. And a concave holding space 321 for collecting the withdrawal coins withdrawn from the deposit / withdrawal port 301a. A bottom opening 322 for dropping coins is opened at the center of the bottom of the holding space 321, and the coins are dropped from the bottom opening 322 and taken into the feeding portion 303 inside the apparatus that leads to the bottom. ing.

  In addition, the concave holding wall 320 is a rocking wall on a part of the rear holding wall 324 (right side in FIG. 3) of the holding space 321 that is an operation position far from the user side, that is, the user side when using the transaction. The vibration plate 100 is supported so as to freely swing.

  On the other hand, the surrounding holding walls other than the rear holding wall 324, in particular, the front holding wall 323 (left side in FIG. 3) on the front side of the user when using the transaction is curved and curved in a concave shape from the upper side to the lower side. A circular arc wall is formed, and coins slide down along the inner surface of the circular arc wall. Further, when a plurality of coins are grasped and taken out from the holding space 321 of the concave holding wall 320 with one hand, a circle considering the movement of the fingertip when the coin is held and the contact with the inner surface of the front holding wall 323. It has an arc-shaped arc wall that is easy to take out.

  In this way, the concave holding wall 320 is formed in an annular shape centering on the axis of the concave holding wall 320, and the rear holding wall 324 is notched at a part of its middle height position so as to be fed upward. A connection port 325 for receiving the coins transported from the transport unit 307 into the concave holding wall 320 is opened. Furthermore, the bottom opening 322 of the concave holding wall 320 is configured to be opened and closed by a tray 330 described later.

  The above-described saucer 330 rotates between the upper position U and the lower position D within the holding space 321 of the concave holding wall 320, and the saucer 330 rotates and moves to the lower position D of the holding space 321. 330 closes the bottom opening 322, and when the tray 330 rotates to the upper position U of the holding space 321 (shown in phantom line in FIG. 3), the bottom opening that the tray 330 has been closed until then The part 322 is configured to be opened.

  Thereby, when the tray 330 stops rotating at the lower closed position, the bottom opening 322 is closed, and the state where the coins accumulated in the concave holding wall 320 are regulated to fall is maintained. On the other hand, when the tray 330 reverses from the lower closed position and stops rotating at the upper retracted position, the bottom opening 322 is opened and the coin in the concave holding wall 320 is dropped from the bottom opening 322. Is taken into the inside of the apparatus below.

  That is, the tray 330 is rotated 180 degrees in the vertical position and stopped, and the coins are put in and out by the vertical rotation stop position of the tray 330. At this time, if the pan 330 is a rotary type, the pan 330 rotates around the shaft center, so that the movement is stable, and the pan 330 rotates in the rotation region of the pan 330, resulting in a compact structure. Moreover, it can be set as the structure without the clearance gap which a foreign material etc. cannot pinch easily.

  Further, since the tray 330 rotates in the concave holding wall 320, it is formed in an arc shape along its curvature, and when it stops rotating at the lower position D, it is in a concave state suitable for coin accumulation and waits. . Coins are accumulated on the upper surface of the arc-shaped tray 330.

  The coin detection sensor S is a sensor that detects the presence or absence of coins in the concave holding wall 320, and the coins are slid down and accumulated on the concave upper surface of the tray 330 that is the lowest position in the concave holding wall 320. Therefore, a plurality of photoelectric detection type sensors are arranged along the arcuate upper surface of the tray 330.

  The coins that have slid down along the slopes of the front holding wall 323, the rear holding wall 324, and the diaphragm 100 are accumulated on the upper surface of the tray 330. The accumulated coins are detected by the coin detection sensor S. FIG. 3 shows a state where three sensors detect one coin C.

  The saucer vibration mechanism 340 includes a vibration plate 100, a rotation support shaft 101, a lever portion 102, an impeller 103, a return spring 104, and vibration amount restriction portions 105a and 105b.

  The diaphragm 100 is disposed on the rear holding wall 324 between the connection port 325 at the above-described intermediate height position on the concave holding wall 320 and the bottom surface opening 322. At this time, the diaphragm 100 is one in which one holding wall of the same shape is independently arranged in a circular or square space in which a part of the rear holding wall 324 is cut out. As shown in FIG. 4, the diaphragm 100 has a central portion on the lower surface side that is the non-coin surface side of the diaphragm 100, and is freely pivoted on a pivotal support shaft 101 supported by another member (not shown). It is supported. The rotation support shaft 101 is provided as a swing support portion, and the vibration plate 100 is rotated forward and backward to generate vibration toward the upper surface side, which is the coin contact surface side, around the rotation support shaft 101. It is pivotally supported by a small amount of rotation.

  Further, a U-shaped lever portion 102 that protrudes at right angles to the tilt direction of the diaphragm 100 is projected from the lower surface side central portion of the diaphragm 100. The lever portion 102 is configured to vibrate upon receiving a beating action at the time of rotational contact when an impeller 103 described later rotates. In consideration of the contact property with the impeller 103, the lever portion 102 protrudes obliquely downward sufficiently long, is provided in a wide width where rotation contact is easily obtained, or other parts are attached to the impeller 103. It is good to make it the shape from which contact of this is obtained appropriately.

  Further, since the diaphragm 100 is pivotally supported by the pivot support shaft 101 at the lower surface side center, the diaphragm 100 has the largest amount of rotation at both ends and the least amount of rotation at the center. For this reason, the central part of the diaphragm 100 has a shape in which the central part of the diaphragm 100 protrudes in a gentle arc shape obliquely upward so that coins can easily slide down. Thereby, even if it is the upper surface side center part of the diaphragm 100, it becomes easy to slip a coin. Therefore, the upper surface of the diaphragm 100 has a shape that allows coins to easily slide down at any position.

  The return spring 104 can be composed of a small coil spring or the like. The upper end of the return spring 104 is connected to the lower surface of the lower side of the diaphragm 100, the lower end is connected to another member (not shown), and the lower side of the diaphragm 100 is biased to be pulled to the non-coin contact surface (lower surface) side. is doing. This urging direction is opposite to the direction of receiving the rotational contact action of the impeller 103, which will be described later, and serves to return the diaphragm 100 to its original position.

  The vibration amount restricting portions 105 a and 105 b are provided to face the upper and lower end portions of the vibration plate 100 in order to restrict the vibration amount of the vibration plate 100. First, the upper part of the vibration plate 100 is configured such that an upper vibration amount regulating portion 105a is provided in a position near the lower surface side of the upper part.

  As a result, when the diaphragm 100 is pivoted about the pivot support shaft 101, the upper lower surface of the diaphragm 100 comes into contact with the upper vibration amount regulating portion 105a. At this time, the amount of rotation of the diaphragm 100 when the upper side rotates downward is regulated.

  Further, a lower vibration amount regulating portion 105b formed at a position opposed to the rear holding wall 324 opposite to the lower end portion is provided opposite to the lower portion of the diaphragm 100. Thereby, when the diaphragm 100 rotates about the rotation support shaft 101, the lower end portion of the diaphragm 100 contacts the lower vibration amount regulating portion 105b. At this time, the amount of rotation of the diaphragm 100 when the lower side rotates downward is regulated.

  As a result, when the diaphragm 100 is rotated about the rotation support shaft 101, the upper and lower ends of the diaphragm 100 are alternately turned by a slight amount of rotation by the upper vibration amount restriction portion 105a and the lower vibration amount restriction portion 105b. Therefore, the range of the rotation amount of the diaphragm 100 is alternately repeated to be small, and a slight vibration is generated.

  In addition, the diaphragm 100 biases the lower side of the diaphragm 100 obliquely downward by the return spring 104, and always presses the lower end portion of the diaphragm 100 against the lower vibration amount regulating portion 105b of the rear holding wall 324 so as to be stationary. ing. For this reason, the diaphragm 100 is maintained so as to be supported at the initial vibration reference position.

  The impeller 103 is provided on a rotating shaft 106 installed at a position facing the upper lower surface side of the diaphragm 100. The rotating shaft 106 is supported by another member and is provided with a periphery extending from a contracted state around the rotating shaft 106 to a substantially radial state by centrifugal force generated as the rotating shaft 106 rotates as shown in FIG. It is configured with three flexible wings 103a equally divided in the direction.

  The rotating shaft 106 rotates the impeller 103 at a desired speed by a driving mechanism (not shown) that rotates the rotational driving force of the impeller driving motor M3 (see FIG. 7) by decelerating the rotating driving force with a reduction gear. By controlling the output of the impeller drive motor M3, the impeller 103 can be arbitrarily rotated or stopped. Further, the rotating shaft 106 is installed in parallel with the rotating support shaft 101, and when the impeller 103 on the rotating shaft 106 stops rotating, the blade 103a contracts on the rotating shaft 106 as shown in FIG. Although it is in a contracted and contracted state, as shown in FIGS. 5 and 6, the wing 103 a continues to rotate in a state of being expanded by centrifugal force. At this time, the impeller 103 is arranged at a position where the three blade tips of the impeller 103 intermittently strike the tip of the lever portion 102 during rotation.

  That is, the blade 103a of the impeller 103 is in a small diameter state contracted along the rotation shaft 106 when the rotation is stopped. Then, only when the impeller 103 rotates, the blade 103a is in a large-diameter state that spreads radially. Therefore, the impeller 103 changes greatly in the radial direction depending on when it rotates and when it stops. When the impeller 103 stops rotating, the blade 103a does not contact the diaphragm 100 because of its small diameter. Therefore, the impeller 103 can be attached with a sufficient attachment interval corresponding to the amount of change in which the wing 103a changes in the radial direction. Therefore, the setting of the attachment position of the impeller 103 is not subject to high-precision restrictions, and the impeller 103 can be easily attached.

  Furthermore, it is suitable for the impeller 103 to use a flexible material such as a rubber material. Thereby, the impulsive sound when the impeller 103 strikes the diaphragm 100 is absorbed, and quietness is obtained. That is, when the impeller 103 strikes the diaphragm 100 and gives an impact, even if the wing 103a hits the diaphragm 100 a lot, it flexes and touches softly, and even if it hits a little, a light and constant impact force is given to the diaphragm 100. Vibration can be generated. Furthermore, since the impeller 103 rotates around one point of the central rotation shaft 106, the movement is stable, the impeller 103 is small and can be arranged in a small space, and the structure for continuously generating minute vibrations by rotation is simple. Therefore, it can be configured at a low cost.

  Further, since the impeller 103 can be configured by disposing an impeller drive motor M3 dedicated to the impeller independent of the conveyance drive system for feeding coins, it can be handled without interfering with the conveyance drive system. For example, when performing clerk processing for coin clogging, internal inspection, etc., the structure is separated when the unit operated by the clerk is opened, so that it becomes easy to handle. Further, the impeller 103 can directly apply vibration to the diaphragm 100 with a simple structure, and the vibration can surely slide the coin down to the bottom surface of the concave holding wall 320.

  In particular, when the impeller 103 strikes the diaphragm 100, the wing 103 a that spreads with the rotation of the impeller 103 begins to strike the lower end side of the lever portion 102 as shown in FIG. 5. In this case, the diaphragm 100 that is integrated and fixed with the lever portion 102 tries to rotate clockwise so as to move away from the restriction position of the lower vibration amount restriction portion 105 b against the urging force of the return spring 104. At this time, the upper and lower surfaces of the diaphragm 100 are in contact with the upper vibration amount restricting portion 105a to be restricted in rotation.

  Thereafter, the impeller 103 further rotates and is separated from the lever portion 102 struck by the impeller blade 103a, so that the diaphragm 100 is returned to its original position by the urging force of the return spring 104 as shown in FIG. I will try. At this time, the diaphragm 100 starts to rotate counterclockwise. Such a right rotation and left rotation of the diaphragm 100 are repeated every time the blade 103 a of the impeller 103 is struck, so that vibration is generated in the diaphragm 100. Based on the occurrence of this vibration, the coins in the inlet / outlet portion 302 are prevented from remaining.

  FIG. 7 shows a control circuit block diagram of the inlet / outlet section 302 provided in the coin deposit / withdrawal mechanism 11. The CPU 71 follows the coin deposit / withdrawal program stored in the ROM 72, the coin detection sensor S, the operation screen 6, and the impeller rotation speed. The adjustment unit 74, the deposit / withdrawal port shutter drive motor M1, the tray drive motor M2, the impeller drive motor M3, and the like are controlled, and the control data is stored in the RAM 73 so as to be readable.

  The CPU 71 detects and confirms the acceptance / removal state of coins, the presence / absence of coins, and the like based on a detection signal of a coin detection sensor S provided as a detection means. Further, when the CPU 71 detects that a foreign object other than coins has been erroneously inserted based on the detection signal of the coin detection sensor S, the CPU 71 provides guidance output of the erroneous insertion information via the operation screen 6 or the voice guidance unit.

  Further, the CPU 71 rotates the impeller 103 to generate vibration after the coin detection sensor S detects withdrawal of the dispensed coin in the concave holding wall 320. Thus, the presence or absence of unremoved coins in the concave holding wall 320 is confirmed and managed by the main control unit 15 having a control function as unremoved confirmation means.

  In addition, the CPU 71 rotates the impeller 103 to generate vibrations after detecting that a tray detection sensor (not shown) has been retracted to a position above the tray 330 in the concave holding wall 320. Thereby, the main control part 15 which has a control function as a non-capture confirmation means confirms and manages the presence or absence of the non-capture of the deposit coin in the concave holding wall 320.

  The CPU 71 drives the deposit / withdrawal port shutter drive motor M1 to open / close the deposit / withdrawal port 301a based on the processing procedure of the deposit / withdrawal transaction. Moreover, based on the control signal of CPU71, the saucer drive motor M2 is driven and the saucer 330 is moved to a closed position and an open position. Further, the CPU 71 is configured to variably control the output of the impeller drive motor M3 to the set rotational speed based on the adjustment signal from the impeller rotational speed adjustment unit 74.

  For example, as shown in FIG. 8, when making a deposit or withdrawal transaction, the vibration according to the denomination coin to be traded by driving the impeller drive motor M <b> 3 is given to the diaphragm 100 to form the concave holding wall 320. It can be set so that all coins deposited and withdrawn can be reliably slid onto the tray 330. These coins have different weights depending on the denomination and have different natural frequencies depending on the denomination. Therefore, it is possible to set an optimum capture condition by giving a vibration corresponding to the money type in consideration of the natural frequency corresponding to the money type.

  Specifically, in the case of a domestic coin, if it is light like a 1-yen coin (1 gram), the impeller 103 is adjusted by adjusting the frequency of the impeller drive motor M3 so as to obtain an optimum vibration applied to the light weight coin. Set the rotation speed of to low. Thereby, the fine vibration most suitable for sliding the 1-yen coin to the diaphragm 100 can be given.

  In case of moderate weight such as 5 yen, 10 yen, 50 yen, 100 yen coin (3.7 to 4.8 grams), impeller drive motor so as to achieve optimum vibration given to medium amount coin The rotation speed of the impeller 103 is set to a medium speed by adjusting the frequency of M3. Thereby, the low vibration most suitable for making the diaphragm 100 slide down a medium amount coin can be given.

  When there is a weight such as a 500-yen coin (7 grams), the rotation speed of the impeller 103 is set to a high speed by adjusting the frequency of the impeller drive motor M3 so as to obtain an optimum vibration applied to the heavy coin. Thereby, it is possible to give the vibration plate 100 high vibration that is most suitable for sliding heavy coins.

  Further, as shown in FIG. 9, when the impeller 103 is rotated, the rubber impeller 103 rotates and strikes the metal diaphragm 100. The impact sound is small due to the nature of contact, and it rotates silently and does not generate harsh sounds. Therefore, while the user is trading, the impeller 103 is rotated to a low speed at which quiet noise can be surely obtained, and coins are deposited and withdrawn, and when the user ends the transaction, the impeller 103 is rotated at a high speed. It is better to execute high-speed capture processing. Thereby, it can operate | move in the state which suppressed the harsh sound as much as possible during the transaction.

Next, the operation of the tray vibration mechanism 340 will be described with reference to FIGS.
4 shows a state in which the impeller 103 is stopped, and the diaphragm 100 is pulled in the direction of the arrow X by the urging force of the return spring 104, and the lower end portion of the diaphragm 100 is the lower vibration amount regulating portion 105b of the rear holding wall 324. It is pressed against and is stationary. When the impeller 103 rotates in a state where the vibration of the diaphragm 100 is on standby, the wing 103a gradually spreads by centrifugal force, and eventually becomes a large diameter state where the lever portion 102 of the diaphragm 100 is hit as shown in FIG. Hits the lever portion 102. The diaphragm 100 rotates rightward in the direction of the arrow Y in the figure by the impact force when hit, but the rotation of the diaphragm 100 is restricted by the upper vibration amount restricting portion 105a of the rear holding wall 324, and the rotation operation is stopped.

  Thereafter, when the blade 103a of the impeller 103 is separated from the lever portion 102 of the diaphragm 100 as shown in FIG. 6, the diaphragm 100 is rotated counterclockwise in the direction of the arrow X in the figure by the urging force of the return spring 104, and again the rear holding wall. It stops in a state where it is pressed against the lower vibration amount regulating portion 105b of 324.

  Further, when the next wing 103a hits the lever portion 102, the diaphragm 100 again rotates clockwise in the arrow Y direction (FIG. 5). The vibration plate 100 vibrates by repeating such rotation operations of the right rotation and the left rotation of the vibration plate 100.

  Due to this vibration, the coin C in contact with the upper surface of the diaphragm 100 jumps up and tilts. The coin slides down the surface of the diaphragm 100 due to the vibration at this time. Further, even if the friction coefficient of the surface of the diaphragm 100 changes due to coin powder or dust on the surface of the diaphragm 100, the coin is surely slid down the surface of the diaphragm 100 and guided to the tray 330. Then, the coin that has slipped down on the tray 330 is detected by the coin detection sensor S.

Furthermore, the vibration generation timing of the tray vibration mechanism 340 will be described.
When the CPU 71 receives a predetermined amount withdrawal instruction from the main control unit 15, in the coin deposit / withdrawal mechanism 11, the CPU 71 accumulates coins of the amount requested for withdrawal in the tray 330, opens the shutter unit 301, and performs transaction. Wait for withdrawal of withdrawal coins by the user (end user). When the coin detection sensor S detects the withdrawal of the coin, the tray vibration mechanism 340 is driven for a predetermined time, and when the coin remains, the remaining coin is slid down on the tray 330. When the coin detection sensor S detects the slipped coin, the end user is notified that there is a coin left, and the end user is prompted to remove the remaining coin.

  Even if the tray vibration mechanism 340 is driven for a predetermined time, if the coin detection sensor S does not detect the remaining coin, it is determined that there is no remaining coin, and the dispensing operation is terminated. Further, while the shutter unit 301 is opened and waiting for the end user to remove the coins, it may be considered that the tray vibrating mechanism 340 is operated so that no residual coins are generated.

  When the CPU 71 receives a deposit processing instruction from the main control unit 15, the coin deposit / withdrawal mechanism 11 opens the shutter unit 301 and waits for coins to be inserted by the end user. When coins are inserted, the shutter 301 is closed, the tray 330 is inverted to open the bottom opening 322, and the coin is dropped from the bottom opening 322 to the lower feeding part 303. Thereafter, the tray 330 is rotated again to return to the original position where the bottom opening 322 is closed.

  At this time, the CPU 71 operates the tray vibration mechanism 340 for a predetermined time, and when coins remain, the residual coins are dropped onto the tray 330. When the coin detection sensor S detects the presence of residual coins, the CPU 71 reverses the tray 330 again to drop the residual coins to the feeding unit 303.

  If the coin detection sensor S does not detect the remaining coins even if the tray vibration mechanism 340 is operated for a predetermined time, it is determined that there is no remaining coins, and all the coins are stored in the temporary storage unit 306 and the depositing operation is finished. To do.

  It is also possible to operate the tray vibration mechanism 340 in the middle of the operation of opening the tray 330, to vibrate a plurality of coins, and to loosen the accumulated coins to encourage the coins to fall. Furthermore, when the coin control is received from the main control unit 15 after waiting for the end user to insert coins during the deposit process, but the coin detection sensor S cannot detect the coins, the tray vibration mechanism 340 is operated for a predetermined time. If the coin detection sensor S cannot detect the coin, it is determined that no coin has been inserted, and the depositing operation is terminated. When the coin detection sensor S detects a coin, it is determined that a deposit coin has been inserted and a deposit process is performed.

  As described above, during the coin processing, the tray vibration mechanism 340 is operated for a predetermined time to confirm that no coin remains reliably. Furthermore, although the installation place of the saucer vibration mechanism 340 has shown the example installed in the rear part holding wall 324 side as shown in FIGS. 3-6, it is not restricted to this, It can also be arranged and comprised in another installation place. Is possible.

  For example, as shown in FIG. 10, not only the tray holding mechanism 340 is provided on the rear holding wall 324 but also the tray holding mechanism 341 having the same function is provided on the front holding wall 323 so that It can also arrange | position so that a vibration may be given to a coin in the front-back position. In this case, the vibration applying region in the concave holding wall 320 is increased, and the generation of residual coins can be prevented more reliably.

  In addition, as shown in FIG. 11, the tray vibration mechanism 341 may be disposed only on the front holding wall 323 side, and vibration may be applied only on the front holding wall 323 side.

  Further, the rotation fulcrum 101 of the diaphragm 100 is not limited to the vicinity of the center of the diaphragm 100 but may be provided on the end side of the diaphragm 100.

  The diaphragm 100 is not limited to a rotary type that generates vibration by repeating forward rotation and reverse rotation, but the rotary shaft 106 of the diaphragm 100 is slidably supported and slidable in the vibration direction. Thus, the vibration plate 100 may be configured to generate vibration.

  Furthermore, the receiving tray 330 may be configured to move the bottom opening 322 to a position where the bottom opening 322 can be opened and closed, and is not limited to the rotary type, and may be moved in the left-right direction to open and close the bottom opening 322 in a sliding manner.

  In addition, the size of the impeller 103 is waiting in a state where the wings 103a contract in the rotation stopped state and face the lever portion 102 in a non-contact state, and the wings 103a spread when the impeller 103 rotates. As long as the position hits the lever portion 102, any distance relationship may be used. For this reason, the installation position of the impeller 103 does not require high-accuracy attachment, and is not subject to the restriction of being set with high accuracy at the time of attachment. Further, the wing 103a can be configured to rotate and come into direct contact with the diaphragm 100 instead of the lever portion 102.

  Further, the rotational speed of the impeller 103 can be arbitrarily changed by changing the frequency of the impeller driving motor M3 described above, and the vibration frequency of the diaphragm 100 can be arbitrarily set and changed by changing the rotational speed. Therefore, it is possible to increase the processing speed of each coin by giving an optimum vibration according to the denominated coin including the foreign currency.

  Furthermore, the number of blades 103a of the impeller 103 is not limited as long as it is one or more. In particular, since the wing 103a formed of a rubber material or the like is flexible and can be taken long, various vibration generation patterns can be obtained depending on the shape of the wing 103a. That is, the vibration generating operation by the impeller 103 can generate a desired vibration by changing the number of the wings 103a, the weight of the wings 103a, the shape of the wings 103a, and the like.

  FIG. 12 shows an example of an impeller 103 with improved durability and quietness. This impeller 103 uses two hollow wings 103a, and the tip side of the wing 103a is wide and thick. As a result, a sufficient strength can be obtained on the tip side of the wing 103a that is in rotational contact, and thus durability is increased. In addition, by forming the wing itself hollow, it has a shape that is highly elastic and easily deforms and absorbs the impact of the wing itself. In addition, the generation of vibration force can be adjusted not only by the rotation speed but also by the shape and weight of each wing 103a.

  As described above, the impeller 103 that vibrates the diaphragm 100 is in a contracted state in which the wing 103a is contracted and folded when the rotation is stopped. When the impeller 103 rotates, the wing 103a is expanded in the radial direction by centrifugal force, and the wing 103a of the impeller 103 intermittently strikes the lever portion 102 opposed in the radial direction to vibrate the diaphragm 100. This is a configuration to be granted.

  Particularly, in the impeller 103, the wing 103a greatly changes in the radial direction depending on the rotation and the stop, and it becomes possible to select a free attachment interval according to the amount of change. For this reason, the setting of the attachment position of the impeller 103 is not subject to high-precision restrictions, and the impeller 103 can be easily attached. In addition, since the impeller 103 is made of a flexible material such as a rubber material, the impact sound is small even when it is struck, and quietness can be obtained. For this reason, no disturbing sound is generated during the transaction. Furthermore, since the impeller 103 is a rotating structure that effectively uses the radial space, the impeller 103 is small and can be arranged in a small space. Further, since the structure for stably generating fine vibration can be simply obtained, the impeller 103 can be configured at low cost.

  The present invention can be applied to all automatic transaction machines that collectively process coins and coins.
