Description

  The present invention relates to a coin processing device and a coin processing method for processing coins.

  2. Description of the Related Art Conventionally, there is a coin processing machine that conveys coins while pressing the coins onto a conveyance path by a conveyance belt.

  When the coins are conveyed while being pressed onto the conveyance path, coins may generate coin dust due to friction between the conveyed coins and the conveyance path. For example, when processing a large amount of 1-yen coins, the coins are conveyed in the same manner as other denominations, so that a large amount of coin dust is likely to be generated. There is a problem that sticking occurs.

  Therefore, there is a coin processing machine in which the height of the entire conveying belt with respect to the conveying path is changed according to the type of coins to be conveyed. For example, when a 1-yen coin is conveyed, the pressing of the 1-yen coin by the conveyor belt is suppressed. Thereby, friction between the coin and the transport path is reduced, and seizure is reduced.

  When the transport surface of the transport path is made of sheet metal, surface treatment for preventing image sticking is performed. Thereby, friction between the coin and the transport path is reduced, and seizure is reduced.

  In addition, coins conveyed along the conveyance path are identified by the identification unit. In recent years, in order to more accurately identify coins, a two-dimensional image of the entire coin being conveyed has come to be collected. Therefore, a glass surface of an image sensor larger than the maximum diameter of coins is provided on a part of the conveyance surface of the conveyance path where the identification unit is arranged, and an image of the entire coin to be conveyed is collected.

  However, as described above, the surface of the transfer path made of sheet metal can be subjected to surface treatment for preventing image sticking, but the glass surface is not subjected to surface treatment for preventing image sticking. Furthermore, despite the fact that the surface of the glass is not subjected to surface treatment for preventing seizure, the coin is pressed with the same pressing force as the transfer surface of the sheet metal subjected to the surface treatment for preventing seizure. Being transported above. For this reason, when a coin conveyed while being pressed by the conveyance path passes over the glass surface of the identification unit, the friction between the coin and the glass surface generates coin powder from the coin, causing a problem of seizure.

Pass over 56. When the branch roller 57 is eccentrically rotated and moves below the branch hole 56, the other side of the coin conveyed along the guide member 32 on the other side is dropped into the branch hole 56 and branched.

  Further, the delivery section 16 has a delivery port 59 opened in the bottom plate 30 and a delivery guide 60 for guiding coins transported to the end of the transport path 26 to the delivery port 59.

  A count sensor unit 61 that counts coins sent from the sending unit 16 is disposed upstream of the sending unit 16 in the transport direction.

  Next, FIGS. 2 and 3 show the vicinity of the identification unit 13 of the transport path 26. FIG.

  Above the glass plate 45 of the identification unit 13, a pressing unit 28 that presses the transport belt 35 (35a) so that the transport belt 35 (35a) comes into contact with coins (indicated by C in FIG. 3) is arranged. . In the present embodiment, two pressing portions 28 are provided, but one pressing portion 28 may be provided, or three or more pressing portions 28 may be provided.

  The pressing portion 28 has a pressing pulley 39. The pressing pulley 39 is rotatably supported at one end of a pulley shaft 64. The other end of the pulley shaft 64 is supported by a pulley support 65. The pulley support 65 is swingably supported by a support shaft 67 inserted into a support hole 66 of the pulley support 65. The support shaft 67 is attached to an attachment portion 68 which is a part of the structure of the coin processing device 10 installed above one side of the transport path 26. The mounting position of the support shaft 67 with respect to the mounting portion 68 can be changed in the vertical direction. FIG. 3 shows a state in which the support shaft 67 is mounted at a position above the mounting portion 68. The pulley support 65 is urged downward by an elastic member 69. The elastic member 69 includes, for example, a coil spring, a torsion spring, a plate spring, and rubber. At the lower part of the pulley support 65, a lowering restricting portion 70 for restricting the swinging lowering position of the pulley supporter 65 that can be swung is protruded. Note that, similarly to the pressing unit 28 of the identification unit 13, a pressing unit 28 other than the identification unit 13 may be configured.

  When the coin denomination to be processed by the coin processing device 10 is a denomination that is liable to burn on the transport surface 33, the attachment 73 is used for the pressing portion 28 of the identification unit 13. A denomination that easily causes seizure on the transport surface 33 is, for example, a 1-yen coin made of aluminum.

  The attachment 73 includes a setting section 74 and a regulating section 75 integrally.

  The setting unit 74 determines that the pressing strength of the pressing unit 28 on the transport belt 35 (35a) by the pressing unit 28 on the identifying unit 13 (including the identifying surface 48 and the second transport surface 33b) is other than the identifying unit 13 (other than the identifying surface 48). And the first transport surface 33a other than the second transport surface 33b) is set to be smaller than the pressing strength of the transport belt 35 (35a, 35b) by the pressing portion 28. It should be noted that the small pressing strength of the conveying belt 35 (35a, 35b) by the pressing unit 28 includes the case where the pressing itself is not performed. No pressing itself includes the case where the conveyor belt 35 (35a) does not come into contact with coins.

  In other words, the setting unit 74 sets the transport unit 27 so that the pressing mode for pressing coins differs depending on the material of the transport surface 33. The transport surface 33 is made of a different material. The transport surface 33 is provided with a surface treatment for anti-seizure, the identification surface 44 of the image sensor unit 42 of the identification unit 13, and the identification surface 48 of the magnetic sensor unit 41 ( Etc.). Further, the material of the transfer surface 33 is the material of the surface treatment when the surface treatment is performed.

  The regulating unit 75 regulates the position of the coin in the width direction by making the passage width of the transport path 26 in the identifying unit 13 narrower than the passage width of the transport path 26 before and after the identifying unit 13 in the transport direction.

  The attachment 73 is detachably attached to the transport path 26. The attachment 73 is mounted on the guide member 32 on the other side. On the upper surface of the guide member 32 on the other side, there is provided a concave portion 76 in which an attachment 73 is disposed. The attachment 73 is disposed in the concave portion 76 and fixed to the guide member 32 on the other side with a plurality of screws 77.

  On the upper surface of the attachment 73, a regulating surface portion 78 with which the lowering regulating portion 70 of the pulley support 65 contacts is formed. The lowering position of the pressing pulley 39 is restricted via the pulley support 65 by the contact of the lowering restricting portion 70 with the restricting surface portion 78. The regulating surface 78 regulates the lowering position of the pressing pulley 39 of the identification unit 13 at a position higher than the lowering position of the pressing pulley 39 other than the identification unit 13. Accordingly, the pressing strength of the conveying belt 35 (35a) by the pressing pulley 39 of the identification unit 13 is smaller than the pressing strength of the conveying belt 35 (35a) by the pressing pulley 39 other than the identification unit 13. Therefore, the setting section 74 includes the restriction surface section 78.

  On the side portion of the attachment 73, a width approaching protrusion 79 is provided to protrude from the guide edge 32a of the guide member 32 on the other side toward the inside of the transport path 26, that is, toward the guide member 31 on one side. The width-shifting projection 79 is provided with a width-shifting guide portion 80 projecting obliquely into the transport path 26 from the guide edge 32a of the guide member 32 on the other side on the upstream side in the transport direction. Guide portion 81 substantially in parallel with the guide edge 31a of one guide member 31 on the downstream side in the direction, and the guide member 32 on the other side from within the transport path 26 in the transport direction downstream of the parallel guide portion 81. It has an evacuation guide section 82 inclined toward the guide edge 32a. This width approaching projection 79 regulates the passage width of the conveyance path 26 in the identification unit 13 to be narrower than the passage width of the conveyance path 26 before and after the identification unit 13 in the conveyance direction, thereby regulating the position of the coin in the width direction. Part 75.

  Next, the processing operation of the coin processing device 10 will be described.

  First, the overall processing operation of the coin processing device 10 will be described with reference to FIG.

  Coins inserted from the hopper above the supply disk 20 are received on the supply disk 20.

  By the start of the processing by the coin processing device 10, the supply disk 20 and the feeding disk 21 rotate, and the respective conveyor belts 35a and 35b rotate.

  The rotation of the supply disk 20 supplies the received coins to the payout disk 21. The rotation of the feeding disk 21 feeds the received coins one by one to the transport path 26.

  In the transport path 26, coins fed one by one from the feeding disk are gripped below the first transport belt 35a, and the coins are transported downstream in the transport direction while being pressed against the transport surface 33 of the transport path 26. I do. In the first transport path section 26a, the coins on the transport surface 33 are transported to the one side by the relative relationship between the direction in which the guide edge 31a of the one guide member 31 extends and the direction in which the first transport belt 35a is stretched. The sheet is conveyed while being shifted to the guide member 31.

  The coin transported by the first transport belt 35a is identified by the identification unit 13. The identification unit 13 magnetically detects the material of the coin when the coin passes through the position of the magnetic sensor unit 41, and photographs the coin with the image sensor 46 when the coin passes through the position of the image sensor unit 42. The image of the coin captured by the image sensor 46 is checked by a not-shown arithmetic unit for any abnormality such as engraving.

  The coin identified as normal by the identification unit 13, that is, the coin identified as not a rejected coin, passes through the first branching unit 14 and is transferred from the first transport path unit 26 a to the second transport path unit 26 b. Conveyed. A rejected coin determined to be unrecognizable by the identification unit 13 is branched off from the transport path 26 by the first branching unit 14. At this time, only the reject coin is branched at the first branching unit 14.

  In the second transport path section 26b, coins fed one by one from the first transport path section 26a are gripped below the second transport belt 35b, and the coins are pressed against the transport surface 33 of the transport path 26. While transporting it downstream in the transport direction. In the second transport path section 26a, coins on the transport surface 33 are transported to the other side from the relative relationship between the direction in which the guide edge 32a of the guide member 32 on the other side extends and the direction in which the second transport belt 35b is stretched. The sheet is conveyed while being shifted to the guide member 32.

  The coin determined by the identification unit 13 to have no abnormality in the marking on the coin surface or the like passes through the second branching unit 15, is counted by the count sensor unit 61, and is sent out from the sending unit 16. Further, the abnormal coin determined by the identification unit 13 to be abnormal in the marking on the coin surface or the like is branched off from the transport path 26 by the second branching unit 15.

  Thus, the coin processing device 10 identifies the inserted coin, counts only normal coins, and sends out the coins.

  Next, a description will be given of a case in which, for example, a 1-yen coin, which is a denomination that is likely to cause burning of a coin being conveyed, is processed.

  When a large number of such coins are continuously conveyed and processed, the seizure of the coins on the conveying surface 33 is likely to occur.

  By applying a surface treatment for anti-seizure of coins at places where the transport surface 33 is made of sheet metal, seizure of coins can be reduced.

  In the identification unit 13, the glass plate 45 of the image sensor unit 42 is used as a part of the transfer surface 33, but this glass plate 45 cannot be subjected to a surface treatment for seizure resistance. Therefore, the seizure of coins on the glass plate 45 is likely to occur.

  Here, in FIG. 5, the pressing strength of the first conveying belt 35a by the pressing unit 28 on the glass plate 45 is different from that of the first conveying belt 35a (or the second conveying belt 35a) by the pressing unit 28 other than the glass plate 45. A comparative example in the case where the pressing strength of the conveyor belt 35b) is equal to the pressing strength is shown. Note that the support shaft 67 is mounted at a lower position with respect to the mounting portion 68 (the mounting position of the support shaft 67 with respect to the mounting portion 68 may be the same position as in the present embodiment shown in FIG. 3), and is lowered. The restricting portion 70 contacts the upper surface of the guide member 32 on the other side. Therefore, as compared with the present embodiment shown in FIG. 3, the lowering position of the pressing pulley 39 is lower, the pressing strength of the first conveyor belt 35a by the pressing pulley 39 is stronger, and coins are removed by the first conveyor belt 35a. The pressing force pressing on the glass plate 45 is strong. In the case of this comparative example, since the pressing force of the coin on the glass plate 45 is large, the frictional force between the glass plate 45 and the coin is large, the coin is shaved by the friction, and metal powder is generated. The phenomenon of burning of coins on the glass plate 45 is likely to occur due to frictional heat generated in the process.

  On the other hand, as shown in FIGS. 2 and 3, in the present embodiment, the setting portion 74 of the attachment 73 reduces the pressing strength of the first conveying belt 35 a by the pressing portion 28 on the glass plate 45, It is set to be smaller than the pressing strength of the first transport belt 35a (or the second transport belt 35b) by the pressing unit 28 other than on the glass plate 45. In this case, since the pressing force of the coin on the glass plate 45 is reduced, the frictional force between the glass plate 45 and the coin is small, the generation of metal powder of the coin due to friction is reduced, and the frictional heat generated by the friction is reduced. This reduces the burning of coins on the glass plate 45.

  In the first transport path portion 26a of the transport path 26, the coins are transported in a state where the coins are shifted to the one guide member 31 with the guide edge 31a of the one guide member 31 as a reference edge. Thus, the discriminated coin in a fixed state can be stably identified by the identification unit 13. However, in order to reduce the seizure of coins during transportation, the pressing force of the coins on the glass plate 45 is reduced, and there is a possibility that the coins cannot be reliably biased to the guide member 31 on one side. is there. Accordingly, as shown in FIGS. 2 to 4, the passage width of the transport path 26 at the identification unit 13 is made smaller than the passage width of the transport path 26 before and after the identification unit 13 in the transport direction by the regulating unit 75 of the attachment 73. To regulate the position of the coin in the width direction. As a result, the coins are conveyed in a state where the coins are shifted to the guide member 31 on one side, and the coins in the fixed state that have been shifted can be stably identified by the identification unit 13.

  As described above, according to the coin processing apparatus 10 of the present embodiment, the pressing strength of the pressing unit 28 of the discriminating unit 13 by the pressing unit 28 by the setting unit 74 increases the pressing strength of the pressing unit 28 other than the discriminating unit 13. Since the pressing strength is set to be smaller than the pressing strength of the transport unit 27, the seizure of coins during transport can be reduced. Similarly, according to the coin processing method of the present embodiment, the pressing strength of the transport unit 27 by the pressing unit 28 in the identification unit 13 is greater than the pressing strength of the transport unit 27 by the pressing unit 28 other than the identification unit 13. Is also set to be small, so that seizure of coins during transportation by the identification unit 13 can be reduced.

  Further, according to the coin processing apparatus 10 of the present embodiment, the setting unit 74 sets the transport unit 27 so that the pressing manner of pressing the coins is different depending on the material of the transport surface 33. Can reduce image sticking. Similarly, according to the coin processing method of the present embodiment, the pressing mode of the transfer unit 27 that presses the coins is made different depending on the material of the transfer surface 33, so that seizure of coins during transfer can be reduced. This makes it possible to reduce the friction of the coin against the glass when coins pass through the transfer surface 33 made of a different material from the other transfer surface 33 such as the transfer surface 33 made of glass, and to burn the coin during transfer. Sticking can be reduced.

  Also, when the transport surface 33 has an identification surface 48 for acquiring information for identifying coins by the identification unit 13, the setting unit 74 sets the pressing strength of the transport unit 27 by the pressing unit 28 on the identification surface 48, Since the setting is made so as to be smaller than the pressing strength of the transport portion 27 by the pressing portion 28 on the transport surface 33 other than the identification surface 48, the seizure of coins during transport on the identification surface 48 can be reduced.

  If the identification surface 48 is glass, surface treatment for seizure resistance cannot be performed, but seizure of coins being conveyed on the identification surface 48 can be reduced.

  When the transfer surface 33 has a first transfer surface 33a that has been subjected to a surface treatment for seizure resistance and a second transfer surface 33b that has not been subjected to the surface treatment for seizure resistance, the setting unit 74 determines Since the pressing strength of the transport unit 27 by the pressing unit 28 on the second transport surface 33b is set to be smaller than the pressing strength of the transport unit 27 by the pressing unit 28 on the first transport surface 33a, the second The burning of coins during transportation on the transportation surface 33b of the coin can be reduced.

  Further, the regulating unit 75 regulates the position of the coin in the width direction of the coin by making the passage width of the transport path 26 in the identification unit 13 narrower than the passage width of the transport path 26 in the transport direction of the identification unit 13 before and after. Even if the pressing strength of the transport unit 27 by the pressing unit 28 decreases, the coin can be transported at a predetermined position in the width direction of the transport path 26.

  The restricting portion 75 may be provided integrally with the attachment 73, may be formed of a single bracket or guide member, or may be a roller that can rotate around an axis perpendicular to the transport surface 33.

  Further, since the attachment 73 has the setting section 74 and the regulating section 75, the setting of the pressing strength of the conveying section 27 by the pressing section 28 and the regulation of the coin in the width direction of the coin can be performed at a time with one attachment 73. .

  Further, since the attachment 73 is detachable from the transport path 26, it is possible to cope with a change in a denomination to be processed by the coin processing device 10. Thus, in the case of the coin processing apparatus 10 that processes a denomination other than a denomination that is likely to cause seizure of coins being conveyed, the attachment 73 does not have to be attached. In this case, the pressing force of the coin on the glass plate 45 increases, and the coin being transported can be more stably identified.

  The setting unit 74 does not use the attachment 73, and by setting the pressing unit 28 at a higher position with respect to the conveying surface 33, the pressing strength of the conveying unit 27 by the pressing unit 28 in the identification unit 13 is: The conveying unit 27 is set so as to be smaller than the pressing strength of the conveying unit 27 by the pressing unit 28 other than the identification unit 13, or the conveying unit 27 is set so that the pressing mode of pressing coins differs depending on the material of the conveying surface 33. You may do so. Therefore, although the setting section 74 and the regulating section 75 are provided integrally by the attachment 73 in the present embodiment, they may be provided separately.

  Next, FIG. 6 shows a second embodiment.

  The pressing pulleys 39, which are all the pressing portions 28, are supported so as to be movable in the vertical direction, and are urged toward the transport surface 33 by the elastic members 69. The elastic member 69 biases the pressing pulley 39, which is the pressing unit 28, at a position other than the identification portion 13 (including the first transport surface 33a other than the identification surface 48 and the second transport surface 33b). And a second elastic member 69b for urging the pressing pulley 39, which is the pressing unit 28, with the identification unit 13 (including the identification surface 48 and the second transport surface 33b).

  The setting section 74 sets the pressing strength of the pressing section 28 on the transport section 27 by the urging force of the elastic members 69 (69a, 69b). That is, the urging force of the second elastic member 69b is set smaller than the urging force of the first elastic member 69a. The setting of the urging force may be performed by using elastic members 69a and 69b having different elastic coefficients and shapes, or by setting different mounting positions so that the same elastic members 69a and 69b are used but the urging forces are different. You may.

  In this way, by setting the pressing strength of the pressing unit 28 to the transport unit 27 by the urging force of the elastic members 69 (69a, 69b), seizure of coins during transport can be reduced.

  In each of the above embodiments, in addition to reducing the pressing force of the coin on the identification surface 48 on the glass plate 45 of the image sensor unit 42, the pressing force of the coin on the identification surface 44 of the magnetic sensor unit 41 is reduced. Is also good. Since the identification surface 44 of the magnetic sensor unit 41 is formed of a non-magnetic material such as zirconia, it is configured as a second transfer surface 33b that is not subjected to a surface treatment for seizure resistance.

  Further, the coin processing device 10 is not limited to being used for a coin counter that counts only a predetermined denomination, but may be used for a coin counter that counts a plurality of denominations. Further, the coin processing device is not limited to a coin counter, and may be used for a coin depositing machine, a coin depositing / dispensing machine, a coin wrapping machine, or the like.
