Description

  The present invention relates to a coin dispensing device that dispenses a predetermined number of coins.

  Conventionally, POS registers, electronic cash registers, deposit / withdrawal management machines, etc., are used to accurately and quickly deliver cash to and from customers by cashiers at stores and cashiers at financial institutions. Coin handling machines have been developed that can automatically deposit and withdraw coins in response to control signals from the cashier.

  Such a coin processing machine includes a coin storage unit that stores coins by denomination, and a coin dispensing device that pays out coins one by one from each of these coin storage units.

  In the coin dispensing device, the coins are conveyed toward the dispensing outlet by the dispensing belt constituting the bottom surface of the coin storage unit, and an interval through which one coin can pass with respect to the upper surface of the dispensing belt is formed in the area before the dispensing outlet. Then, the coins are made into a single layer state by the reversely arranged reverse rollers, and the width direction intersecting the coin payout direction is set to the width of one coin by the guide members arranged in both side regions of the payout belt. It regulates and pays out coins one by one from the payout opening. Further, when a predetermined number of coins to be paid out are detected by the sensor, the coin stopper prevents passage of the next coin of the predetermined number and pays out the predetermined number of coins.

  The coin stopper is disposed on the dispensing belt at a position close to the guide member on one side, and is provided at the tip of the solenoid plunger. The coin stopper is retracted upward away from the dispensing belt by excitation of the solenoid. The solenoid is de-energized by detecting a predetermined number of coins with a sensor and is lowered by the bias of the spring of the solenoid so as to hit the predetermined number of coin surfaces. The coin moves in the payout direction while sliding against the coin stopper, so that the coin advances from the gap between the predetermined number of coins and the next coin onto the payout belt and blocks the passage of the next coin. (For example, refer to Patent Document 1). Thereby, even when coins are continuously paid out at high speed, only a predetermined number of coins can be reliably paid out.

  By the way, a coin has a peripheral protrusion formed on the peripheral portion of the coin surface, a recess is formed inside the peripheral protrusion, and a coin pattern or the like is formed in the recess, and the peripheral surface protrudes from the coin surface. The part is the most protruding.

  For this reason, when the coin stopper enters the indented portion inside the peripheral protrusion of the coin surface, the coin stopper may be caught by the peripheral protrusion, and the stagnation or clogging of the coin may occur.

Therefore, the diameter of the coin stopper is increased or the shape is long in the direction orthogonal to the coin payout direction (see, for example, Patent Document 2), and the coin stopper is placed on the peripheral protrusion of the coin, The coin stopper is prevented from being caught by the peripheral protrusion.
Utility Model Registration No. 2520891 (Page 4-5, Figure 5-6) JP 2003-272024 A (page 4, FIG. 6)

  However, since the coin stopper must be advanced onto the payout belt through the gap between the guide member on one side and the predetermined number of coins and the next coin, the diameter of the coin stopper is increased or the shape is devised. Even if an attempt is made, it cannot be made sufficient, and it has been difficult to ensure that the coin stopper is placed on the peripheral protrusion of the coin.

  The coin stopper is arranged close to the guide member on one side. Since the solenoid that moves the coin stopper back and forth is rattled due to play of the plunger, the coin stopper is placed between the coin stopper and the one side guide member. There is a case where the peripheral protrusion of the coin surface is sandwiched, and there is a problem that stagnation or clogging of the coin occurs.

  As shown in FIG. 1, on both sides of the payout belt 59, the coins C to be paid out from the payout outlet 62 with the width in the direction intersecting the payout direction being limited to the width of one coin are in a single row state. Guide members 64 and 65 are arranged. These guide members 64 and 65 have guide surfaces 66 and 67 facing each other on the payout belt 59, and the distance between the guide surfaces 66 and 67 facing each other is larger than the diameter of one coin to be processed. The size is smaller than the diameter of two sheets.

  On the end side in the payout direction of the guide members 64, 65, that is, on the front side of the payout port 62, a biasing portion 68 that inclines in a direction from one side of the payout belt 59 toward the other side as it goes in the payout direction of the coin C. , 69 are formed. The one-side guide member 64 of the one-side guide member 64 is disposed on the payout belt 59, and the other guide member 65 of the one-side guide portion 69 is disposed outwardly from the other side of the payout belt 59.

This solenoid 74 allows the passage of the coin C in the payout direction by pulling up the plunger 75 by excitation and retracting the coin stopper 73 upward, and as an urging means (not shown) provided in the solenoid 74 by releasing the excitation. By causing the plunger 75 to protrude downward by the biasing of the spring and the coin stopper 73 to advance onto the payout belt 59, the passage of a predetermined number of coins C in the payout direction can be prevented.

  As shown in FIG. 3, the coin stopper 73 has a circular cross-sectional shape, the tip surface is formed into a flat surface, and the peripheral portion of the tip surface is chamfered. This chamfer dimension is smaller than the thickness of the minimum thickness coin, and the coin stopper 73 can reliably stop the minimum thickness coin.

  As shown in FIG. 1, a guide surface missing portion 76 that is recessed in an arc shape with respect to the guide surface 66 is formed in a part of the offset portion 68 of the guide member 64 on one side. A part of the coin stopper 73 is located outside the guide surface missing portion 76 and is arranged outside the guide surface 66 on one side. The guide surface missing portion 76 is formed in an arcuate recess facing through a predetermined gap that does not interfere with the outer peripheral surface of the coin stopper 73 having a circular cross section.

  The diameter of the coin stopper 73 is generally about 2 mm in order to allow the coin stopper 73 to enter the gap between the guide surface 66 and the coin C before and after the payout direction. In order to allow the coin stopper 73 to enter the gap between the coins C before and after the payout direction, it can be increased to about 4 mm.

  The coin stopper 73 advances to a position past the center of the coin by releasing the excitation of the solenoid 74 when the optical axis 71 of the optical sensor 72 is shielded by the coin C paid out by the payout belt 59. Thus, the positional relationship with the coin detection position by the optical sensor 72 and the timing for releasing the excitation of the solenoid 74 are set.

  As shown in FIGS. 4, 6, and 7, the dispensing transfer means 39 is stretched along the front-rear direction of the machine body 11 at the side of the payout port 62 of all the coin storage and payout portions 38. A coin transport belt 78 is provided, and the coins C paid out from the payout outlet 62 of each coin storage / payout unit 38 are placed on the payout transport belt 78 and transported forward. Above the front end portion of the dispensing transport belt 78 in the coin transport direction, a reverse rotation roller 79 is provided in a manner to form an interval through which only one coin C can pass. The reversing roller 79 rotates in a direction opposite to the coin conveying direction of the dispensing conveying belt 78, and is in an unaligned state on the dispensing conveying belt 78 that is going to be fed forward by the rotation of the dispensing conveying belt 78. Coins C are fed out in a line with one layer.

  At the front end portion of the dispensing conveyor belt 78, a discharge belt 80 for discharging the coin C conveyed by the dispensing conveyor belt 78 to the coin dispensing port 19 is disposed. At the position of the discharge belt 80, a payout detection sensor 81 for detecting the number of coins C to be paid out to the coin dispensing port 19 is disposed.

  By the way, in the coin C, a peripheral protrusion 85 is formed on the peripheral portion of the coin surface 84, an inner recess 86 is formed inside the peripheral protrusion 85, and a coin pattern or the like is formed in the inner recess 86. From the coin surface 84, the peripheral protrusion 85 protrudes most.

  Next, the operation of the coin depositing and dispensing machine will be described.

  First, the depositing process of the coin depositing and dispensing machine will be described (see FIGS. 5 and 6).

  The coin C to be deposited is inserted into the feeding mechanism 31 from the coin slot 14, and a coin detection sensor (not shown) of the feeding mechanism 31 detects that the coin C has been inserted on the feeding belt 43, whereby the feeding mechanism 31 is changed. At the same time, the transfer belt 55 is rotated to start the depositing operation.

  The feeding mechanism 31 aligns the coins C in a single layer and feeds them to the delivery means 37, and the delivery means 37 feeds the coins C one by one into the identification passage 32 and rotates each of the protrusions of the conveyor belt 55. Deliver to 56.

  In the identification passage 32, the coin C is identified by the identification unit 48 while being pushed and conveyed by the protrusion 56 of the conveyance belt 55.

  As a result of the identification, the coin C identified as an appropriate coin is conveyed into the classification passage 34, classified by the denomination classification gate 52 corresponding to the identification result in the identification unit 48, and stored in the coin storage / dispensing unit 38. To do.

  In addition, rejected coins that cannot be identified as a result of identification are rejected by the reject section 49 of the rejection passage 33, and are discharged from the coin dispensing port 19 to the withdrawal tray 18 by the withdrawal transport means 39 and returned.

  Next, a withdrawal process of the coin depositing and dispensing machine will be described (see FIG. 4).

  For example, in accordance with a withdrawal command signal from the POS register, the dispensing belt 59 rotates and the reverse rotation roller 63 rotates in reverse, and the non-aligned coins C on the dispensing belt 59 in each coin storage unit 58 are arranged in a single layer. And move it in the payout direction.

  In the coin storage / dispensing unit 38 of the corresponding denomination, the coin stopper 73 is retracted and the coin C is paid out from the payout outlet 62 to the payout conveying means 39 by the payout belt 59. The coin C to be paid out is detected by the optical sensor 72 and the number of payouts is counted.

  In the coin storage / disposal unit 38 for non-withdrawal denominations and the coin storage / disposal unit 38 for withdrawing denominated denominations, the coin stopper 73 is advanced onto the dispensing belt 59 to dispense coins C. regulate.

  Then, the coin C is dispensed from the coin dispensing port 19 to the dispensing tray 18 by the dispensing conveying means 39. The operation start of the dispensing transport means 39 may be performed simultaneously with the start of the dispensing operation from the coin storage / dispensing unit 38 or after the completion of the dispensing operation from all the coin storage / dispensing units 38.

  Next, a coin dispensing operation from the coin storage / dispensing unit 38 will be described.

  FIG. 2 (a) shows a standby state. In this standby state, the solenoid 74 is turned off, and the coin stopper 73 advances onto the payout belt 59 by the bias of the spring of the solenoid 74 to stop the coin C.

  As shown in FIG. 2 (b), when the dispensing of the coin C is started, the solenoid 74 is turned on and the coin stopper 73 is retracted upward, so that the coin C released from the stopped state by the coin stopper 73 is dispensed by the dispensing belt 59. To move in the payout direction.

  As shown in FIG. 2 (c), when a predetermined number of coins C1 shields the optical axis 71 of the optical sensor 72 in order to pay out a predetermined number of coins C, a solenoid 74 as shown in FIG. 2 (d). Is turned off, and the tip end surface of the coin stopper 73 advances downward by the bias of the spring of the solenoid 74 and comes into contact with the coin surface 84 of the predetermined number of coins C1. At this time, the front end surface of the coin stopper 73 comes into contact with the position of the peripheral protrusion 85 on the coin surface 84 of the predetermined number of coins C1 and past the center of the coin C1.

  Even after the coin stopper 73 contacts the predetermined number of coins C1, the frictional force between the payout belt 59 and the predetermined number of coins C1 is larger than the frictional force between the coin stopper 73 and the predetermined number of coins C1, A predetermined number of coins C1 are moved in the payout direction by the payout belt 59.

  As shown in FIG. 2 (e), when the predetermined number of coins C1 passes and is removed below the coin stopper 73, the coin stopper 73 is placed in the gap between the predetermined number of coins C1 and the next coin C2. The coin stopper 73 advances on the payout belt 59.

  As shown in FIG. 2 (f), the predetermined number of coins C1 are paid out from the payout opening 62, and the next coin C2 of the predetermined number comes into contact with the coin stopper 73 that has advanced on the payout belt 59, so that the payout belt 59 Even if it continues to rotate, the predetermined number of coins C2 are stopped and the payout is restricted.

  Then, a guide surface missing part 76 is formed on the guide surface 66 of the one side guide member 64, and a part of the coin stopper 73 is positioned on the guide surface missing part 76 and arranged outside the one side guide surface 66. Therefore, the coin stopper 73 can always be brought into contact with the peripheral protrusion 85 of the coin C, and the coin stopper 73 does not enter the inner periphery of the peripheral protrusion 85 of the coin C. The peripheral edge projection 85 of the coin C is not sandwiched between the guide member 64 and the coin stopper 73 can be inserted between the predetermined number of coins C and the next coin C. The cross-sectional shape of the coin C can be increased, and the coin stopper 73 can be reliably brought into contact with the peripheral protrusion 85 of the coin C.

  For this reason, the coin stopper 73 can be smoothly dispensed without causing the coin C contacting the coin surface 84 to stagnate or clog, and the next coin C can be stopped reliably.

  Further, since the guide surface 66 of the guide member 64 on one side is inclined toward the other side of the payout belt 59 as it goes in the payout direction of the coin C, the coin C and the coin that are offset by the guide surface 66 on the one side The positional relationship with the stopper 73 becomes constant, and the coin stopper 73 can function reliably.

  Further, since the cross-sectional shape of the coin stopper 73 is circular, positioning in the circumferential direction is unnecessary, and the influence of rattling can be reduced as compared to the case of a shape other than circular. For example, if the coin stopper has a shape that is long in the direction perpendicular to the coin payout direction, positioning in the circumferential direction is necessary, and the coin will be hit by the play of the solenoid plunger that moves the coin stopper back and forth. The contacting coin stopper is rotationally displaced, and the coin cannot be stopped reliably. For this reason, it is necessary to provide another mechanism for preventing the coin stopper from rotating.

  Further, since the coin stopper 73 is advanced on the coin surface 84 of the coin C to be paid out and past the center of the coin C, the load applied to the coin C to be paid out can be reduced, and the coin C can be stagnated or jammed. Can be paid out smoothly.

  Next, FIG. 8 shows a second embodiment.

  A recess 91 is formed at the center of the tip of the coin stopper 73. As a result, the contact area between the front end surface of the coin stopper 73 and the peripheral protrusion 85 of the coin C can be reduced, the load applied to the coin C to be dispensed can be reduced, and the coin C can be smoothly dispensed without stagnation or clogging. be able to.

  A chamfered portion for preventing the coin C from being caught on the coin surface 84 is formed on the outer peripheral edge of the front end surface of the coin stopper 73 and the inner peripheral edge on the recessed portion 91 side.

  In addition, the hollow part 91 may be any of a concave shape or an opening opened up and down.

  Next, FIG. 9 shows a third embodiment, and FIG. 10 shows a fourth embodiment.

  The guide surface 66 of the guide member 64 on one side in the payout direction of the coin C is inclined toward the other side of the payout belt 59 in the payout direction of the coin C as it goes upstream from the payout outlet 62 to the guide surface missing portion 76. Further, the coin C passing through the guide surface missing portion 76 is caught at the downstream side from the guide surface missing portion 76 of the guide surface 66 of the guide surface 66 of the one side guide member 64 in the payout direction of the coin C. Form at no angle.

  For example, as shown in FIG. 9, the downstream side from the guide surface missing part 76 of the guide surface 66 of the guide member 64 on one side in the payout direction of the coin C is the outside of the recess of the guide surface missing part 76 (the back side of the recess). ) To the other side of the payout belt 59 as it goes in the payout direction of the coin C, or as shown in FIG. 10, the guide surface of the guide surface 66 of the guide member 64 on one side in the payout direction of the coin C The downstream side from the missing portion 76 is formed in parallel with the rotation direction of the payout belt 59 from the guide surface missing portion 76.

  In this way, the upstream of the guide surface 66 of the guide member 64 on one side in the payout direction of the coin C from the payout outlet 62 to the guide surface missing portion 76 is directed to the other side of the payout belt 59 as it goes in the payout direction of the coin C. By inclining the coin stopper 73, the positional relationship between the coins and the coin stopper 73 that are offset by the guide surface 66 of the guide member 64 on one side becomes constant, so that the coin stopper 73 can function reliably. In the payout direction, the downstream side of the guide surface 66 of the guide surface 66 of the guide member 64 is different from the angle at which the upstream side is inclined, and the angle at which the coin C passing through the guide surface missing portion 76 is not caught is formed. Therefore, even if the guide surface missing portion 76 is provided in the guide surface 66 on one side, the coin C to be paid out can be smoothly paid out without stagnation or clogging.

  The guide surface missing portion 76 is not limited to the shape recessed from the guide surface 66, but may be formed by an opening that is divided into an upstream side and a downstream side and separated.
