  The coin bridging phenomenon is considered to occur when a withdrawal process occurs, such as when all collections are instructed, or when there is a discrepancy in the collection operation with the specified amount or number of coins. It occurs on the rear side of the reservoirs 34A to 34F and the overflow reservoir 34G, that is, around the rear wall 38. The coin bridge elimination mechanism 75 of the present embodiment can be set to operate arbitrarily by a control unit (not shown). However, in the case of the above-described total collection or when a count mismatch occurs and a coin is not released for an arbitrary predetermined time, it is automatically set in advance. It is preferable to set it to operate automatically.

  When the drive unit 47 is displaced from the second displacement position, which is the standby position, to the first displacement position, first, the coin bridge cancellation mechanism 75 is arbitrarily preset to a position where the drive motor 59 is arbitrarily set in advance. Drive at a different speed. The third interlocking member 56, the second interlocking member 51, and the first interlocking member 53 operate in conjunction with the drive, and the rotating shaft 45 fixed to one end of the first interlocking member 53 rotates in conjunction with it. Then, the connecting member 49 whose one end is fixed to the rotating shaft 45 is interlocked and rotates about the rotating shaft 45 substantially downward in a side view. In accordance with the displacement of the drive unit 47 to the first displacement position, the arm-like operation is supported from below by the connecting member 49 and is brought into contact with the connecting member 49 by the first biasing member 48. The part 64 moves toward the first operating position. That is, the first arm 46 of the arm-like operating portion 64 is rotated substantially downward in a side view around the rotation shaft 45 in conjunction with the connecting member 49 by the urging force of the first urging member 48. In the process of displacement of the first arm 46, the second arm 65 connected to the first arm 46 by the second urging member 70 is separated from the fixed shaft 71, thereby the second urging member 70. The urging force causes a force to return to a substantially T shape when viewed from the side with the other end of the first arm 46 as the center, and the second arm 65 is substantially on the conveyor belt 35 that is inclined upward toward the front of the machine body. The rotary member 68 comes into contact with the front conveyor belt 35 before returning to the T-shape, and thereafter contacts the conveyor belt 35 until it returns. Therefore, the position arbitrarily set in advance by which the drive motor 59 is driven is located at one end of the second arm 65 even when the second arm 65 has returned to a substantially T shape by the urging force of the second urging member 70. It is preferable that the rotation member 68 provided is set and controlled at a position where it comes into contact with the conveyor belt 35. When coming into contact with the conveyor belt 35, the rotating member 68 is rotated on the conveyor belt 35 by the driving force of the conveyor belt 35.

  When actually removing the coin bridge, the rotating member 68 may abut against a part of the coin bridge, so that the coin bridge may be destroyed and eliminated, or the abutted coin is conveyed on the conveyor belt 35 and the rear part. The coin bridge may be eliminated by using the reaction when riding on the wall 38. Therefore, when the coin bridge eliminating mechanism 75 is operated, it is preferable that the conveying belt 35 is also controlled by a control unit (not shown) so as to repeat forward and reverse rotation. Further, as described above, the rotating member 68 is not limited to a circle but may be a triangle, a quadrangle, a six, or the like as long as it has a cross-sectional shape that can be rotated in accordance with the forward rotation and the reverse rotation of the conveyance belt 35 when contacting the conveyance belt 35. A polygon such as a square may be used, and the material may be a material having a high friction coefficient even if it is not a synthetic rubber. Note that, for example, in the coin processing machine having the withdrawal storage portions 34A to 34F and the overflow storage portion 34G provided in parallel with a plurality of denominations in which the cross-sectional shape of the rotating member 68 is not a circle but a polygonal shape. When the rotating member 68 of the arm-like operation unit 64 contacts and rotates on the conveyor belt 35 in one withdrawal storage unit without accumulated coins, the arm-like operation unit 64 or the conveyor belt 35, and further the side wall 37. The vibration is applied to the peripheral mechanism including the arm-like operation part 64 including the side wall 37 of the other withdrawal storage part adjacent thereto or the rotating member 68, etc. This makes it easier to eliminate the coin bridge in the withdrawal reservoir.

  Here, the drive unit 47 is driven to the first displacement position regardless of whether or not coins are accumulated. When the coins are not actually accumulated, the drive unit 47 is different. As a result, the arm-like operation unit 64 is not displaced to the first operation position, and an overpressure is applied to the conveyance belt 37 that is in contact with the accumulated coins, which may cause damage. In order to prevent this harmful effect, the arm-like operating portion 64 and the drive portion 47 are connected by the first urging member 48, and when contacting the deposited coin, the first urging member 48 is deformed. Avoiding overpressure. That is, even if the drive unit 47 including the connecting member 49 moves to the first displacement position, as shown in FIG. 8, the arm supported rotatably on the rotating shaft 45 and supported by the connecting member 49 from below. After stopping at the position corresponding to the deposited coin C, the slidable operating portion 64 is separated from the connecting member 49 while deforming the first urging member 48, thereby avoiding overpressure on the conveyor belt 37. To do.

  Next, when the drive unit 47 is displaced from the first displacement position to the second displacement position, the drive motor 59 is first driven at a speed arbitrarily set in advance to a position arbitrarily set in advance. The third interlocking member 56, the second interlocking member 51, and the first interlocking member 53 operate in conjunction with the drive, and the rotating shaft 45 fixed to one end of the first interlocking member 53 rotates in conjunction with it. Then, the connecting member 49 whose one end is fixed to the rotating shaft 45 is interlocked and rotates about the rotating shaft 45 substantially upward in a side view. In accordance with the displacement of the drive unit 47 to the second displacement position, the arm-like operation unit 64 is supported by the connecting member 49 from below and is brought into contact with the connecting member 49 by the first biasing member 48. However, it rotates about the rotation shaft 45 in the side view substantially upward and moves toward the second operation position.

  In the process of displacing the first arm 46, as shown in FIG. 2, the other end of the second arm 65 contacts the fixed shaft 71, and the second urging member 70 is centered on the other end of the first arm 46. It rotates approximately 90 degrees against the urging force, and is stored in a substantially straight line in the second operating position, rather than in a substantially T shape in a side view. Thereby, it is suitable without entrainment at the time of conveyance of a deposited coin. In addition, it is still more preferable to attach the board | plate material for prevention of entrapment of a deposited coin to the upper surface of the 2nd arm 65, and the upper surface of the 1st arm 64.

  According to the coin bridge elimination mechanism 75 of the present embodiment described above, the drive unit 41 and the drive unit 41 are utilized by utilizing the open upper space of the withdrawal storage units 34A to 34F and the overflow storage unit 34G. The arm-like motion unit 64 that is linked to the coin eliminates the coin bridge, so that the coin bridging phenomenon of the deposited coins without changing the thickness of the side wall 37 of the withdrawal reservoirs 34A to 34F and the overflow reservoir 34G. Can be reliably solved and the demand for downsizing of coin processing machines can be met.

  Further, the drive unit 41 can be installed without greatly changing the configuration of the withdrawal storage units 34A to 34F and the overflow storage unit 34G, and the demand for downsizing the coin processing machine can be met. .

  In addition, by connecting the drive unit 41 and the arm-like operation unit 64 with the first biasing member 3 represented by a spring, the overload when the arm-like operation unit 64 comes into contact during actual coin accumulation is conveyed. A so-called “escape mechanism” that is not applied to the belt 35 can also be provided. That is, when the drive unit 41 is driven to the first displacement position (the first operation position where the arm-like operation unit 64 is in contact with the transport belt 35) regardless of whether or not coins are accumulated, the coins are actually accumulated. Otherwise, when it is deposited, the arm-like operation part 64 is not displaced by the thickness of the deposited coin, and overpressure is applied to the conveying belt 35 that contacts through the deposited coin, which may cause damage. Absent. In order to prevent the adverse effect, the connecting member 49 of the driving unit 41 receives the arm-like operating part 64 from the lower side, and the connecting member 49 and the arm-like operating part 64 are connected by the first biasing member 48. When contacting the coin, it is avoided by displacing the first urging member 48. In addition, the second displacement position (the second operation position for storing the arm-like operation unit 64) is performed in conjunction with the return operation of the connecting member 49, one end of which is fixed to the rotating shaft 45. The operation unit 64 itself does not need to include a drive unit.

  Further, in the process in which the arm-like operation unit 64 is displaced to the first operation position (a position where the conveyance belt 35 and the tip of the arm-like operation unit 64 abut), the rotating member 68 abuts on the coin bridge and can be eliminated. At the same time, since the rotating member 68 is rotatable, the coin bridge can be eliminated without overloading the coins in contact therewith.

  In addition, when the arm-like operation unit 64 is displaced to the first operation position, even if the rotating member 68 abuts on the conveyance belt 35, the rotation is possible, so that the conveyance belt 35 is overloaded. It can be avoided.

  Further, it becomes possible to expand the movable range of the arm-like operation unit 64, and in particular, a coin processing having a coin depositing unit that employs a conveyor belt 35 that is inclined upward toward either the front or the rear of the coin processing machine. It is effective for the machine. That is, at the second operation position (the storage position of the arm-like operation unit 64), the other end of the second arm 65 contacts the fixed shaft 71, and the second urging member 70 is centered on the other end of the first arm 46. It rotates approximately 90 degrees against the urging force, and is stored in a substantially straight line instead of a substantially T shape in side view. Here, in the process in which the first arm 46 is displaced to the first operation position (a position where the conveying belt 35 and one end of the arm-shaped operation unit 64 abut), a substantially T-shape is generated by the urging force of the second urging member 70. On the conveyor belt 35 having a shape that is inclined upward toward either the front or the rear of the fuselage, either the front or the rear before the second arm 65 returns to a substantially T shape. Then, the rotating member 68 comes into contact with the conveyor belt 35 until it comes back. Therefore, the coin bridge can be reliably eliminated over a wide range.

  Further, in the process in which the arm-like operating portion 64 is displaced to the first operating position, the rotating member 68 having a high friction coefficient can easily come into contact with the deposited coins, and the coin bridge can be eliminated more reliably. The rotating member 68 may be made of a material having a high friction coefficient even if it is not a synthetic rubber.

  Further, in the coin processing machine having the withdrawal storage units 34A to 34F and the overflow storage unit 34G provided in parallel for each denomination, the arm-like operation unit 64 is a single withdrawal storage unit without accumulated coins. When the rotating member 68 is rotated in contact with the conveying belt 35, the rotating member 35 is formed into a polygonal shape, so that the arm-like operation unit 64 or the conveying belt 35 and the peripheral mechanism including the side wall 37 vibrate. This vibration vibrates the arm-like operation part 64 or the rotating member 68 including the side wall 37 of the other storage part for withdrawal, which is adjacent to the other storage part for withdrawal. The coin bridge can be easily eliminated.

  Moreover, by applying to the withdrawal reservoirs 34A to 34F and the overflow reservoir 34G of the coin processor, it is possible to reliably prevent coins from remaining in the withdrawal reservoirs 34A to 34F and the overflow reservoir 34G.

  When there is a count mismatch in the collection operation with total collection, amount, and number specified by the control of the control unit, and coins are not released for an arbitrary predetermined time, the withdrawal storage units 34A to 34F and the overflow storage Coin residual in the part 34G can be reliably prevented.

  In the configuration of the coin bridge eliminating mechanism 75 of the present embodiment, the drive unit 47 is provided behind the rear wall 38 and in the vicinity of the upper portion of the rear wall 38, and one end of the arm-like operation unit 64 is arranged in the vicinity of the upper portion of the rear wall 38. Thus, the other end of the arm-like operating portion 64 is pivoted downward about the rotation shaft 45 in the vicinity of the upper portion of the rear wall 38. The rotation shaft 45 is used for the withdrawal storage portions 34A to 34F and the overflow. The rotating member 68 may be disposed at the upper part near the center of the upper space space of the storing part 34G, and the other end of the arm-like operating part 64 may be arranged. The withdrawal storing parts 34A to 34F and the overflow storing part 34G The arrangement can be appropriately changed depending on the structure.

  In addition, the configuration of the coin bridge elimination mechanism 75 of the present embodiment is not limited to the withdrawal reservation units 34A to 34F and the overflow storage unit 34G, but a temporary storage unit of a denomination that temporarily stores coins selected by denomination. Furthermore, the present invention can be applied to a shared temporary storage unit that is not related to the denomination. For example, if a control that is activated each time the temporary hold is canceled is set, coins remaining in the temporary storage unit can be reliably prevented.
