Description

  The present invention relates to a coin processing device that pays out coins one by one.

  For example, in a vending machine or a ticket vending machine, a plurality of coins can be put in a lump, and the coins that are put in a lump are received in a coin lump-in part, and coins are separated and fed one by one in this coin lump-in part. There is a configuration in which coins fed out one by one are identified by a coin identifying unit.

  In the conventional coin batch input unit, coins that have been batch input are received on a conveyor belt, the coins are transported by the conveyor belt, and the passage of overlapping coins is restricted by a reverse roller disposed opposite to the conveyor belt. By doing so, there is a configuration for paying out coins one by one (for example, see Patent Document 1). In general, the reverse rotation roller has a curved surface with no irregularities, and the thickness of two thinnest coins larger than the thickest coin among the coins to be processed between the conveyor belt and the conveyor belt. A smaller interval allows for the passage of coins one by one.

  In addition, there is a configuration in which coins that have been put together are received in a rotating disk, and the coins are separated and fed one by one by the rotation of the rotating disk (for example, see Patent Document 2).

In addition, the coin identification unit used in vending machines, ticket vending machines, etc., will require a certain amount of time to identify the coin, so it will be rejected if the interval between coins to be sent is not more than 0.5 seconds, for example. It has become. Therefore, in addition to providing rollers and shutters in the passage through which the inserted coins pass, sensors are provided on the upstream and downstream sides of the rollers and shutters, and the rollers are rotated and stopped based on the detection of these sensors. In addition, there is a configuration in which a shutter is opened and closed, and coins that are continuously inserted are sent to a coin identifying unit at a predetermined interval (see, for example, Patent Document 3). However, this configuration requires a sensor and a control unit that controls driving of the roller and the shutter, which is expensive.

And an open position detecting sensor 62 such as a photo interrupter having a light receiving portion.

  Below the open area of the passage plate 42, a reject passage 63 is formed which receives clogged coins or foreign matter released downward by opening the passage plate 42 and guides it to the return port 16.

  Further, the reverse rotation roller 39 is disposed to face the center of the passage surface 47 of the passage plate 42. That is, the rotation shaft 66 of the reverse roller motor 65 as the reverse roller driving unit attached to the other side surface of the side plate 33 of the frame 30 is projected from one side surface of the side plate 33 of the frame 30 to the upper region of the passage plate 42. A reverse rotation roller 39 is attached to the rotation shaft 66. Then, by driving the reverse roller motor 65, the reverse surface is rotated so that the peripheral surface of the reverse roller 39 facing the passage plate 42 rotates in a direction opposite to the coin feeding direction.

  The reverse roller 39 is made of metal, has a thickness dimension in the passage width direction smaller than the diameter dimension of the coin, and a large protrusion 67 having a large protruding dimension on the peripheral surface and a plurality of small protrusions having a protruding dimension smaller than the large protrusion 67. 68 are projected at predetermined intervals. The large protrusions 67 and the small protrusions 68 have a substantially triangular shape, and the top is formed flat. In this example, the two large protrusions 67 are two, and one small protrusion 68 is located at a relatively close position. Projected. That is, one small protrusion 68 is positioned between one of the two large protrusions 67, and a plurality of small protrusions 68 are positioned between the other of the two large protrusions 67. The distance between the two large protrusions 67 of the reverse rotation roller 39 is determined by the rotation speed of the reverse rotation roller 39, and if the rotation speed is too low, the effect of breaking the coins is reduced. It is preferable to set the speed.

  As shown in FIG. 3 (b), the distance L1 between the large protrusion 67 of the reverse rotation roller 39 and the passage surface 47 of the passage plate 42 at a fixed position is the coin to be processed ( However, it is set to be smaller than the thickness of the thinnest coin. As shown in FIG. 3A, the distance L2 between the small protrusion 68 of the reverse rotation roller 39 and the passage surface 47 of the passage plate 42 located at a fixed position is the thickness of the thickest coin among the coins to be processed. It is set to be smaller than the thickness of two of the thinnest coins. As shown in FIG. 3 (c), when a coin is strongly bitten between the large protrusion 67 of the reverse rotation roller 39 and the passage surface 47 of the passage plate 42 located at a fixed position, the passage plate 42 With the shaft as a fulcrum, it is configured to oscillate downward against the urging force of the spring 50 so that the distance from the reverse rotation roller 39 is increased.

  As shown in FIGS. 4 to 7, the feeding mechanism 40 includes a pair of cam rollers 70 and 71 coaxially attached to the rotation shaft 66 on both sides of the reverse rotation roller 39, and the rotation of the cam rollers 70 and 71. A pair of leaf springs 72 and 73 that open and close between the passage surface 47 of the passage plate 42 are provided.

  The pair of cam rollers 70 and 71 use the same parts, and are attached to the rotary shaft 66 so that the attachment positions differ by 180 °.

  Of the pair of leaf springs 72, 73, one leaf spring (first leaf spring) 72 is a leaf spring for holding down the coin next to the coin to be fed, and the other leaf spring (second leaf spring) 73. Is a regulating leaf spring that regulates coin feeding at regular intervals.

  Each of the leaf springs 72 and 73 is formed of a leaf spring material and is disposed along the coin feeding direction in the upper region of the coin passage 38 on both sides of the reverse rotation roller 39. The base end on the upstream side in the coin feeding direction Are attached to the guide plate 43 on the upstream side with screws 76, and elasticity is given upward so that the intermediate portion always abuts against the lower surface of each cam roller 70, 71. ing.

  The distal ends of the leaf springs 72 and 73 on the downstream side in the coin feeding direction are extended so that the other leaf spring 73 is longer than the one leaf spring 72, and a presser portion 77 and a restricting portion 78 are provided at the respective distal ends. Each is bent downward. The presser portion 77 and the restricting portion 78 can be advanced and retracted into the coin passage 38 through the opening 79 formed in the downstream guide plate 44 by the rotation of the cam rollers 70 and 71. That is, the holding portion 77 can be moved back and forth between the advance position in contact with the passage surface 47 of the passage plate 42 and the retracted position that allows passage of coins, and the restricting portion 78 is more than the passage surface 47 of the passage plate 42. Also, it is possible to move forward and backward between an advance position that advances to the lower side and a retreat position that allows passage of coins. The passage plate 42 is formed with a notch 80 that avoids interference with the restricting portion 78. Each position, that is, the interval between the presser portion 77 and the restricting portion 78 is set on the coin surface of the next coin that is in contact with the restricted coin while the restricting portion 78 restricts one coin. The holding portion 77 has a dimensional relationship that can be pressed by contact.

  Further, as shown in FIG. 2 and FIG. 7, when a coin inserted from the coin insertion slot 15 reaches the position of the reverse rotation roller 39, a light projecting unit and a light receiving unit that are shielded by the coin and detect the coin are provided. A first sensor 82 such as a photo interrupter is provided. A second sensor 83 such as a photo interrupter having a light projecting unit and a light receiving unit that are shielded by the coins that are fed out and is detected by the coins that are fed out is disposed at the exit of the coin passage 38 that feeds the coins to the coin identification unit 26. Yes.

  Further, the coin processing device 14 includes a control unit (not shown) that controls the coin processing device 14. The control unit has a function of driving the reverse roller motor 65 when the first sensor 82 detects a coin, and stopping the reverse roller motor 65 when a predetermined time elapses after no coin is detected. If the second sensor 83 does not detect the coin for a certain period of time while detecting the coin, it is determined that there is a coin jam or foreign matter mixed in front of the coin passage 38 or the reverse rotation roller 39, and the passage plate 42 is opened by the opening mechanism 53. Automatically opens downward and returns coins and foreign matter to the return port 16, and when the second sensor 83 detects a coin and a predetermined time has elapsed, a coin jam has occurred on the coin identification unit 26 side. A function to judge that an error has occurred, and when the passage plate 42 is opened, if the opening position detection sensor 62 does not detect the opening of the passage plate 42, it is judged that something is caught and the passage plate 42 is once closed. Lito several times to open again Is i, or as a last resort if the ability to error notification, upon opening of the passage plate 42, and has a function of stopping a predetermined time passage plate 42 in consideration of the drop time of the coin and foreign matter in the open position.

  Next, the operation of the coin processing device 14 will be described.

  The coins inserted into the coin insertion slot 15 are fed into the coin passage 38 and reach the position of the reverse rotation roller 39 due to the inclination of the passage surface 47 of the passage plate 42. When the first sensor 82 detects that the coin has reached the position of the reverse roller 39, the reverse roller motor 65 is driven to rotate the reverse roller 39.

  The reverse rotation roller 39 rotates while the large protrusion 67 and the small protrusion 68 sequentially face the passage surface 47 of the passage plate 42, but during the period in which the small protrusion 68 of the reverse rotation roller 39 faces the passage surface 47 of the passage plate 42, Coins pass one by one under the reverse roller 39.

  Further, as shown in FIG. 1 (a), the coin C2 located on the coin C1 advances further downstream than the coin C1 located on the passage plate 42 side, and between the reverse rotation roller 39 and the passage plate 42. When a coin enters in a wedge shape, it is difficult to break the coin with the small protrusion 68 of the reverse rotation roller 39 even if the reverse rotation roller 39 is rotating, but the coin is broken by the action of the large protrusion 67 of the reverse rotation roller 39. Can pass under the reverse rotation roller 39 one by one. That is, as shown in FIGS. 1B and 1C, when the large protrusion 67 of the reverse rotation roller 39 rotates to the position of the coin C2, the large protrusion 67 scoops up the coin C2 and moves it upstream. Meanwhile, the coin C1 moves to the downstream side of the coin C2, and can pass through the lower side of the reverse rotation roller 39 in order from the coin C1 located on the passage surface side. Moreover, as shown in FIG. 1 (d), when the large projection 67 is removed from the coin C2, the coin C2 tries to return to the original position again. The large protrusion 67 scoops up the coin C2 and moves it upstream, while the coin C1 moves further downstream than the coin C2, and the lower side of the reverse roller 39 is surely placed in order from the coin located on the passage surface side. Can be passed.

  Thus, the coins are guided in the coin feeding direction by the inclination of the passage surface 47 of the passage plate 42, and the coins are separated and passed one by one by the reverse rotation roller 39 arranged oppositely on the passage surface 47 of the passage plate 42. In addition, the large protrusion 67 and the small protrusion 68 provided on the peripheral surface of the reverse rotation roller 39 allow the coin to enter the wedge shape between the reverse rotation roller 39 and the passage surface 47, Can be separated and passed one by one, and there is no need to use a conveyor belt, a rotating disk, etc., and it can be made small and inexpensive.

  Moreover, since the large protrusions 67 are provided at two locations on the peripheral surface of the reverse rotation roller 39, even if there is a possibility that the coins that have been collapsed by only one large protrusion 67 may return to the posture before they collapse again, the second The large protrusion 67 of the coin can surely break the coin.

  Furthermore, since the reverse roller 39 is made of metal, it is superior in durability and cost compared to the case where it is used for general rubber, and even if the reverse roller 39 is made of metal, the large protrusion 67 is small. By providing the projections 68, the coins can be reliably separated and fed out one by one.

  In addition, when the coin passes through the lower side of the reverse rotation roller 39, if the large protrusion 67 of the reverse rotation roller 39 comes into contact with the coin surface of the coin, the reverse roller motor 65 is generally overloaded. As shown in FIG. 3 (c), a coin is sandwiched between the large protrusion 67 of the reverse rotation roller 39 and the passage plate 42 so that a load exceeding a predetermined value is applied to the passage plate 42. Since the passage plate 42 moves from a fixed position in the direction in which the gap with the reverse rotation roller 39 is increased against the urging by the spring 50, the coin can be prevented from being caught.

  Further, coins that have passed under the reverse rotation roller 39 are fed one by one by a feeding mechanism 40 with a certain interval. That is, as shown in FIG. 5 (a), the cam roller 70 moves the pressing portion 77 of the first leaf spring 72 to abut against the passage plate 42, and the lower portion of the reverse rotation roller 39 is moved to the pressing portion 77. The passed coin C11 comes into contact and stops. The cam roller 71 moves the restricting portion 78 of the second leaf spring 73 to close the coin passage 38.

  As shown in FIG. 5B, when the cam rollers 70 and 71 rotate, the presser portion 77 of the first leaf spring 72 moves away from the passage plate 42 and the coin C11 held by the presser portion 77 is moved. Moves in the coin feeding direction and stops by abutting against the restricting portion 78 of the second leaf spring 73 in a state of closing the coin passage 38, and the subsequent coin C12 abuts on this coin C11.

  As shown in FIG. 5 (c), the pressing portion 77 of the first plate spring 72 moves toward the passage plate 42 by the rotation of the cam roller 70, and the pressing portion 77 is a regulating portion of the second plate spring 73. It abuts against the coin surface of the second coin C12 following the first coin C11 that abuts against 78 and holds the coin C12 sandwiched between the passage plates 42.

  As shown in FIG. 5 (d), the second leaf spring 73 moves away from the passage plate 42, only the first coin C11 moves in the coin feeding direction, and the second coin C12 is held. Maintain state.

  Thereafter, as shown in FIG. 5A, the restricting portion 78 of the second leaf spring 73 moves to a state in which the coin passage 38 is closed.

  In this way, the first leaf spring 72 and the second leaf spring 73 of the feeding mechanism 40 alternately open and close the coin passage 38, and the coins that have passed one by one under the reverse rotation roller 39 are spaced at regular intervals. The coins can be fed out in the coin feeding direction, so that the coins can be reliably processed by the coin identifying unit 26 which is a post-processing step.

  In this feeding mechanism 40, the leaf springs 72, 73 open and close between the passage surface 47 of the passage plate 42 in accordance with the rotation of the cam rollers 70, 71 provided coaxially with the reverse rotation roller 39, so that a coin is fixed. The feeding mechanism 40 can be fed at intervals, and no special electrical equipment or control for adjusting the feeding interval is required, and the feeding mechanism 40 can be configured simply and inexpensively.

  Further, when both the first sensor 82 and the second sensor 83 no longer detect coins, the reverse roller motor 65 is stopped when a predetermined time has elapsed.

  As shown in FIG. 2 (a), if the second sensor 83 does not detect the coin for a certain period of time while the first sensor 82 detects the coin, the coin path as shown in FIG. 2 (b). It is determined that coins are jammed or foreign matter is mixed in front of 38 or the reverse roller 39, the passage plate 42 is automatically opened downward by the opening mechanism 53, and coins and foreign matter are automatically returned to the return port 16 through the reject passage 63. When the passage plate 42 is opened, the passage plate 42 is stopped at the open position for a predetermined time in consideration of the falling time of coins and foreign matters. After the coins and foreign matter are returned, the passage plate 42 is returned to the original fixed position.

  When the passage plate 42 is opened, if the opening position detection sensor 62 does not detect the opening of the passage plate 42, it is judged that something is caught and the passage plate 42 is temporarily closed and then retried several times. If it still does not work, an error is reported.

  If the second sensor 83 detects a coin and a predetermined time has elapsed, it is determined that a coin jam has occurred on the coin identification unit 26 side, and an error is notified.

  The number of the large protrusions 67 of the reverse rotation roller 39 may be one, but if it is two as described above, the coin can be broken down more reliably. Further, depending on the relationship between the rotation speed and the diameter of the reverse rotation roller 39, etc. There may be more than two.
