  Hereinafter, the detail of each component of such a coin processing unit 10 is demonstrated below.

  As described above, the coin processing unit 10 is provided with the storage unit 20, and one or a plurality of coins input into the machine body through the coin input port 11 are stored in the storage unit 20. Further, the feeding means 22 for feeding coins one by one from the storage unit 20 has a rotating plate 24 extending in a substantially horizontal state, and the rotating plate 24 has a counterclockwise rotation in FIG. It rotates in the direction (arrow direction in FIG. 2). The coins stored in the storage unit 20 are agitated in the storage unit 20 by the rotation of the turntable 24. Further, as shown in FIG. 2 and FIGS. 5 to 9, a rubber member is provided on the surface of the outer peripheral edge region 24 c of the rotating disk 24. The coins stored in the storage unit 20 are moved toward the outer peripheral edge region 24c by the centrifugal force generated by the rotation of the turntable 24, and the friction generated between the rubber member on the surface of the outer peripheral edge region 24c and the coins. It is fed out to the transport unit 40 by force.

  In addition, as shown in FIG. 2, in the vicinity of the turntable 24, feed means 26 for sending coins on the turntable 24 to the transport unit 40 is provided.

Further, in the vicinity of one of the guide members 32 and 33, a restricting means 34 for restricting the operation of feeding coins fed from the rotating disk 24 to the transport unit 40 is provided. The restricting means 34 has a movable member 35 that rotates in both the clockwise and counterclockwise directions in FIG. Here, the movable member 35 permits the stop position for stopping the coin as shown in FIGS. 5 and 6 and the allowance for feeding the coin into the transport unit 40 by the feeding means 26 as shown in FIG. It is movable between positions.

  Further, the movable member 35 is biased by a biasing mechanism 36a such as a torsion spring that biases the movable member 35 so as to be positioned at a stop position as shown in FIG. Is provided. By such an urging mechanism 36a, the movable member 35 is normally maintained at the stop position as shown in FIG. Here, the force applied to the movable member 35 by the urging mechanism 36 a is larger than the coin feeding force by the turntable 24 of the feeding means 22, but the coin is caused by the protrusion 30 provided on the feeding cam 28 of the feeding means 26. It is weaker than the force that is pressed. For this reason, if the coins fed by the turntable 24 of the feeding means 22 only come into contact with the movable member 35, the coins are stopped by the movable member 35 and sent to a circulation belt 42 (described later) of the transport unit 40. There is nothing. On the other hand, when the coin is pushed from behind by the protrusion 30 provided on the feeding cam 28 of the feeding means 26 and the coin comes into contact with the movable member 35, the movable member 35 is pushed by the coin and the shaft 36 is centered. Then, the movable member 35 rotates counterclockwise in FIG. 5 or the like against the biasing mechanism 36a, and rotates to an allowable position as shown in FIG. Details of the coin feeding operation from the turntable 24 to the transport unit 40 by the feeding means 26 will be described later.

  As shown in FIGS. 2 and 5, a feeding detection sensor 38 for detecting coins fed by the rotary disk 24 of the feeding means 22 is provided in the vicinity of the feeding cam 28 of the feeding means 26. That is, when the coin fed out by the turntable 24 of the feeding means 22 reaches the position of the feeding detection sensor 38, this coin is detected by the feeding detection sensor 38.

  FIG. 14 is a schematic diagram showing the configuration of the feeding detection sensor 38. As shown in FIG. 14, the feeding detection sensor 38 has a light emitting part 38e and a light receiving part 38r, and the light emitted from the light emitting part 38e is received by the light receiving part 38r. One of the light emitting part 38e and the light receiving part 38r is provided on the upper side and the other of the light emitting part 38e and the light receiving part 38r is provided on the lower side with respect to the coin passing path in the vicinity of the feeding cam 28 of the feeding means 26. It has been. Thereby, the passage path of the coin is sandwiched between the light emitting section 38e and the light receiving section 38r, and when the coin passes through the passage path, the light emitted from the light emitting section 38e is blocked by the coin and the light receiving section 38r. Will not reach. Accordingly, the feeding detection sensor 38 detects the passage (arrival) of the fed coin.

  Further, as shown in FIG. 5 and the like, a pressing portion 39 is provided in the vicinity of the guide members 32 and 33. Details of the configuration of the pressing portion 39 will be described with reference to FIG. FIG. 10 is a longitudinal sectional view showing the configuration of the pressing portion 39 in the coin processing unit 10 shown in FIG. As shown in FIG. 10, the pressing portion 39 has a pinch ball 39a and a spring member 39b (compression spring) attached to the pinch ball 39a, so that the upper end portion of the spring member 39b is fixed. It has become. More specifically, as shown in FIG. 10, a cover member 24b is provided above the turntable 24 of the feeding means 22, and the pinch balls 39a and the spring members 39b of the pressing portion 39 are provided on the cover member 24b. It is provided so as to pass through the formed through hole. As shown in FIG. 10, when the coin C is not positioned below the pinch ball 39a, the pinch ball 39a floats with a slight gap with respect to the rotating disk 24. On the other hand, when the coin C on the turntable 24 reaches a position below the pinch ball 39a, the coin C is pressed downward by the urging force of the spring member 39b. Specifically, the coin C between the rotating disk 24 and the pinch ball 39a is pressed toward the rotating disk 24 with a force of, for example, about 100 g by the urging force of the spring member 39b. As a result, the frictional force acting between the rubber member provided on the surface of the outer peripheral edge region 24c of the turntable 24 and the coin C increases, and the turntable 24 against the coin C pressed downward by the pinch ball 39a. The feeding force increases.

  The transport unit 40 has a circulation belt 42 (moving member) that circulates in a counterclockwise direction in FIG. Further, as shown in FIGS. 3 and 5 to 9, the circulation belt 42 is provided with projections 44 such as pins at equal intervals, and the coins fed into the transport unit 40 by the feeding means 26 are circulated. By being pushed by each protrusion 44 provided on the belt 42, the sheet is moved one by one along the conveyance path of the conveyance unit 40. As shown in FIG. 2, the circulation belt 42 is stretched around a plurality of pulleys including pulleys 43 and 46, and the pulley is driven by a drive motor (not shown) provided on one of the plurality of pulleys. Is rotated so that the circulation belt 42 circulates in the counterclockwise direction in FIG. 2 (the arrow direction in FIG. 2). The pulley 43 rotates counterclockwise about the shaft 43a. A rotating plate (not shown) is attached to the rotating shaft of the pulley 46, and the rotating phase of the rotating plate is detected by a rotating plate phase detection sensor 48 (see FIG. 4).

  In the present embodiment, a coin feeding device that feeds coins is configured by the storage unit 20, the feeding unit 22, the feeding unit 26, the regulating unit 34, the transport unit 40, and the like of the coin processing unit 10.

  As shown in FIG. 2, the transport unit 40 is provided with an identifying unit 50 that identifies the denomination, authenticity, and correctness of the coins transported by the transport unit 40. In addition, the aspect of the identification part 50 is not limited to such a thing, What is necessary is just to be able to identify at least the denomination of the coin conveyed by the conveyance part 40.

  Further, as shown in FIG. 2, a plurality of sorting means 60 (seven sorting means 60 a to 60 g) are arranged along the transport unit 40, and each sorting means is based on the coin identification result by the identifying unit 50. By 60, coins are sorted into denominations. In addition, as described above, a plurality of storage units 68 are provided corresponding to each distribution unit 60, and the coins distributed by each distribution unit 60 are stored in the corresponding storage unit 68. .

  Details of the configuration of each distribution means 60 will be described with reference to FIGS. 11 and 12. 11 is a configuration diagram showing details of the configuration of the sorting means 60 in the coin processing unit 10 shown in FIG. 2, and FIG. 12 shows the configuration of the pressing portion 66a provided in the vicinity of the sorting means 60a shown in FIG. It is a longitudinal cross-sectional view which shows an effect | action. In FIG. 11, coins are conveyed rightward (in the direction of the arrow in FIG. 11) by the circulation belt 42 of the conveyance unit 40.

  In the following description, the sorting means 60a and 60b among the plurality of sorting means 60 will be described as an example. As shown in FIG. 11, the sorting unit 60 a includes a sorting plate 62 a for closing an opening provided on the transport surface 45 of the transport unit 40, and a coin detection sensor 64 a. When a denomination coin corresponding to the sorting means 60a is detected by the coin detection sensor 64a, the sorting plate 62a is driven, and the sorting plate 62a opens upward from the opening of the transport surface 45 of the transport unit 40. . As a result, the coins conveyed by the projections 44 provided on the circulation belt 42 enter the opening of the conveyance surface 45 and are sent to the storage unit 68 corresponding to the sorting means 60a.

  FIG. 15 is a schematic diagram showing the configuration of the coin detection sensor 64a. As shown in FIG. 15, the coin detection sensor 64a has a light emitting part 64e and a light receiving part 64r, and the light emitted from the light emitting part 64e is received by the light receiving part 64r. Then, one of the light emitting part 64e and the light receiving part 64r is provided on the upper side with respect to a predetermined passing position of coins corresponding to the operating time of the sorting means 60a, and the light emitting part 64e and the light receiving part The other of 64r is provided on the lower side. Thereby, the predetermined passage position of the coin is sandwiched between the light emitting portion 64e and the light receiving portion 64r, and when the coin reaches the passage position, the light emitted from the light emitting portion 64e is blocked by the coin and received. It will not reach the part 64e. Thereby, the coin detection sensor 64a detects that the coin has reached a predetermined passing position.

  Here, the threshold value of the amount of light received by which the light receiving unit 64r of the coin detection sensor 64a of the present embodiment detects “arrival of coin” (identifies “arrival of coin” when the amount of received light is not reached). The light receiving unit 38r of the feeding detection sensor 38 is higher than the threshold value of the received light amount for detecting “passage of coins” (identifying “passage of coins” when the received light amount is not reached). That is, the detection sensitivity of the light receiving unit 64r of the coin detection sensor 64a is higher (easier to detect) than the detection sensitivity of the light receiving unit 38r of the feeding detection sensor 38. Thus, when the feeding detection sensor 38 detects the coin as a coin, it is possible to avoid the problem that the detection target is not detected as a coin in the coin detection sensor 64a (detected as a coin by the feeding detection sensor 38). In this case, it is guaranteed that the detection target is always detected as a coin in the coin detection sensor 64a).

  Further, as shown in FIG. 11, pressing portions 66a and 66b are provided in the vicinity of the distributing means 60a and 60b. Here, the pressing portion 66a corresponding to the sorting means 60a is arranged slightly upstream (left side in FIG. 11) from the coin detection sensor 64a of the sorting means 60a in the coin transport direction. As shown in FIG. 12, the pressing portion 66a has a pinch ball 66p and a spring member 66q (compression spring) attached to the pinch ball 66p, and the upper end portion of the spring member 66q is fixed. It has become so. When no coin is located below the pinch ball 66p, the pinch ball 66p floats with a slight gap with respect to the transport surface 45 of the transport unit 40. On the other hand, when the coin pushed and conveyed by the projection 44 provided on the circulation belt 42 reaches a position below the pinch ball 66p, the pinch ball 66p is pushed up by the coin, and the coin is transferred to the conveyance surface. 45 and the pinch ball 66p. At this time, the coin is pressed downward by the urging force of the spring member 66q.

  By providing such a pressing portion 66a, the following effects can be obtained. That is, as shown in FIG. 12A, the coin C moves integrally with the circulation belt 42 by the frictional force that acts between the circulation belt 42 and the coin C, and the coin C moves to the protrusion 44 of the circulation belt 42. Even if it has preceded from the projection part 44 without being pushed from behind by this, as shown in FIG. 12B, when this coin C comes into contact with the pinch ball 66p of the pressing part 66a, this pinch ball The coin C is stopped by 66p. Then, as shown in FIG. 12 (c), when the projection 44 of the circulation belt 42 catches up with the coin C and the coin C is pushed rightward in FIG. 12 by the projection 44, the coin C causes the pinch ball 66p. Is pushed upward, and the coin C passes through the region between the transport surface 45 and the pinch ball 66p. As described above, since the pressing portion 66a is provided corresponding to the sorting means 60a, when a coin is detected by the coin detection sensor 64a of the sorting means 60a, the coin is pushed by the projection 44 of the circulation belt 42. In this state, the protrusion 44 does not precede. As a result, it is possible to prevent a distribution error by the distribution means 60a.

  Further, as shown in FIG. 2, the coin processing unit 10 is provided with a protrusion detection sensor 52 that detects the presence or absence of each protrusion 44 provided on the circulation belt 42 of the transport unit 40.

  Details of the configuration of the protrusion detection sensor 52 will be described with reference to FIG. 3 is an AA arrow view showing the configuration of the protrusion detection sensor 52 in the coin processing unit 10 shown in FIG. As shown in FIG. 3, the protrusion detection sensor 52 has a light emitting portion 52a and a light receiving portion 52b, and the light emitted from the light emitting portion 52a is received by the light receiving portion 52b. Then, when the circulating belt 42 circulates in the counterclockwise direction in FIG. 2, the protrusion 44 provided on the circulating belt 42 reaches a position between the light emitting portion 52a and the light receiving portion 52b. The light emitted from the light emitting part 52a is blocked by the protrusion 44 and does not reach the light receiving part 52b. Thus, the protrusion detection sensor 52 detects that the protrusion 44 is provided on the circulation belt 42, in other words, that the protrusion 44 is not missing from the circulation belt 42.

  Moreover, in the money depositing / withdrawing machine 1 of this Embodiment, the control part 70 which controls each component of the money depositing / withdrawing machine 1 is provided. In FIG. 4, the functional block diagram of the money depositing and dispensing machine 1 of this Embodiment is shown. As shown in FIG. 4, the control unit 70 includes a feeding unit 22, a feeding unit 26, a transport unit 40, a protrusion detection sensor 52, an identification unit 50, a sorting unit 60, and a rotating plate phase detection sensor 48 of the coin processing unit 10. Etc. are connected. Here, the coin identification information by the identification unit 50 is sent to the control unit 70. Information detected by the protrusion detection sensor 52 and the rotating plate phase detection sensor 48 is also sent to the control unit 70. The control unit 70 sends command signals to the feeding unit 22, the feeding unit 26, the transport unit 40, the sorting unit 60, and the like of the coin processing unit 10 to control these components.

  Further, as shown in FIG. 4, the coin processing unit 10 feeds the coins stored in the storage units 68 from the storage units 68 and conveys them to a position where they can be taken out from the outside of the machine body. The withdrawal means 84 is also connected to the control unit 70. And the control part 70 controls the payment means 84 so that the coin accommodated in each accommodating part 68 may be withdrawn out of the body.

  In addition, although the control part 70 shown in FIG. 4 also controls each component of the banknote processing unit 12, description is abbreviate | omitted here.

  As shown in FIG. 4, a storage unit 72, an operation display unit 74, a printing unit 78, an interface 80, and the like are connected to the control unit 70. The storage unit 72 stores the processing status of money by the coin processing unit 10 and the banknote processing unit 12 of the money depositing / dispensing machine 1, the amount of coins and banknotes stored in the coin processing unit 10 and the banknote processing unit 12, and the like. It has become so.

  Further, in the present embodiment, the storage unit 72 is also configured to store detection information of each protrusion 44 by the protrusion detection sensor 52.

  The operation display unit 74 includes, for example, a touch panel as described above. As shown in FIG. 1, the operation display unit 74 is located above the coin processing unit 10 and the banknote processing unit 12, and the housing of the money depositing and dispensing machine 1. It is provided on the front side. The operator can input various commands to the control unit 70 of the money depositing / dispensing machine 1 through the operation display unit 74. In the operation display unit 74, the processing status of money by the coin processing unit 10 and the banknote processing unit 12 of the money depositing and dispensing machine 1, the amount of coins and banknotes stored in the coin processing unit 10 and the banknote processing unit 12, etc. Is displayed.

  The printing unit 78 includes, for example, a printer and the like, and the processing status of money by the coin processing unit 10 and the banknote processing unit 12 of the money depositing and dispensing machine 1 and the presence of coins and banknotes stored in the coin processing unit 10 and the banknote processing unit 12. It prints high grades. Further, the interface 80 allows the control unit 70 to transmit and receive signals to and from an external device 82 such as a host device.

  Next, the operation of the money depositing / dispensing machine 1 of the present embodiment having such a configuration, particularly the coin processing unit 10 will be described. The operation of the coin processing unit 10 described below is performed by the control unit 70 controlling each component of the coin processing unit 10.

  First, when the operator inserts one or a plurality of coins into the body through the coin insertion slot 11, the inserted coins are stored in the storage unit 20 of the coin processing unit 10. At this time, coins are accumulated on the rotating disk 24 disposed below the storage unit 20. At this time, the turntable 24 is always rotating in the counterclockwise direction in FIG. 2 about the shaft 24a.

  The coins on the turntable 24 move toward the outer peripheral edge region 24c of the turntable 24 by the centrifugal force generated by the rotation of the turntable 24, and the coins moved to the outer peripheral edge region 24c of the turntable 24 are guided members 32, One sheet is fed out through the area between 33. When the feeding detection sensor 38 detects the passage (arrival) of coins, the feeding cam 28 of the feeding means 26 receives the coins fed from the rotating plate 24 and feeds them into the circulation belt 42 of the transport unit 40. Such an operation will be described in detail with reference to FIGS.

  FIG. 5 is a view showing a state when the coin is waiting before the coin is fed into the transport unit 40 by the feeding cam 28 of the feeding means 26. More specifically, the feeding detection sensor 38 detects the passage (arrival) of the coin, and the feeding means until the projection 44 such as a pin provided on the circulation belt 42 in the transport unit 40 reaches a predetermined position. 26, the feeding cam 28 is stopped, and the coins C1, C2, and C3 fed out from the rotary disk 24 of the feeding means 22 are put on standby at the positions shown in FIG. At this time, the coin C1 at the head comes into contact with the movable member 35 of the restricting means 34, and the feeding of the coin C1 to the transport unit 40 is restricted by the movable member 35.

  When the projection 44 provided on the circulation belt 42 in the transport unit 40 reaches a predetermined position, the feed cam 28 rotates in the clockwise direction about the shaft 28a as shown in FIG. As a result, the coins C <b> 1 at the head are pushed from the rear toward the circulation belt 42 of the transport unit 40 by the protrusions 30 provided on the feeding cam 28. At this time, the feeding cam 28 feeds the coin C <b> 1 to the circulation belt 42 of the transport unit 40 against the regulation by the movable member 35 of the regulating means 34. That is, the coin C1 pushed by the protrusion 30 of the feeding cam 28 is pressed against the force of the urging mechanism 36a such as a spring provided on the movable member 35, while pushing the movable member 35, and the circulation belt of the transport unit 40. Move toward 42. As a result, as shown in FIG. 7, the movable member 35 permits the coins to be fed into the transport unit 40 from the stop position (see FIGS. 5 and 6) where the coins are stopped (see FIG. 7). Move to. Then, as shown in FIG. 7, when the coin is delivered to the circulation belt 42 of the transport unit 40, the movable member 35 of the regulating means 34 immediately returns to the stop position by the urging mechanism 36a (see FIG. 8). Accordingly, as shown in FIG. 8, the movable member 35 of the regulating means 34 regulates that the next coin C <b> 2 is fed into the circulation belt 42 of the transport unit 40. Further, when the coin C1 is fed into the circulation belt 42 of the transport unit 40, the feeding cam 28 of the feeding means 26 is stopped again, and the next coin C2 is put on standby. Further, as shown in FIG. 8, the coins C <b> 1 fed from the turntable 24 to the circulation belt 42 of the conveyance unit 40 are pushed by the protrusions 44 provided on the circulation belt 42, and enter the conveyance path of the conveyance unit 40. Will move along.

  If the regulating means 34 is not provided, the following problems may occur. FIG. 9 is a diagram illustrating a coin feeding operation from the turntable 24 of the feeding unit 22 to the transport unit 40 when the regulating unit 34 is not provided. As shown in FIG. 9, when the restricting means 34 is not provided, when the feeding cam 28 of the feeding means 26 starts to rotate from the stopped state, the leading coin C1 is provided on the feeding cam 28. Before being pushed from behind by the projected portion 30b, it is pushed toward the circulation belt 42 of the transport unit 40 by being pushed from behind by the subsequent coin C2. That is, the coin C1 at the head is pushed from the rear by the next coin C2 while contacting the protrusion 30a of the feeding cam 28 in front of the coin C1. Therefore, when the leading coin C1 is fed to the circulation belt 42 of the transport unit 40 by the feeding cam 28 of the feeding means 26, the next coin C2 comes into contact with the leading coin C1 as shown in FIG. However, since it moves toward the circulation belt 42, the next coin C <b> 2 may bite into the gap between the projection 30 b of the feed cam 28 and the guide member 32. In this case, the feeding cam 28 cannot be rotated any more and a mechanical error occurs. On the other hand, when the restricting means 34 is provided as shown in FIGS. 5 to 8, even if the feeding cam 28 of the feeding means 26 starts to rotate from the stopped state, the coin C1 at the head is movable by the restricting means 34. The member 35 restricts the feeding of the transport unit 40 to the circulation belt 42 (see FIG. 5). The coin C1 at the head is not fed from the rear by the projection 30 of the feeding cam 28 and is fed into the circulation belt 42 of the transport unit 40 against the regulation of the regulating means 34. For this reason, the next coin C <b> 2 does not bite into the gap between the protrusion 30 of the feeding cam 28 and the guide member 32.

  As described above, the pressing portion 39 is provided in the vicinity of the guide members 32 and 33. Thus, for example, in the state shown in FIG. 5, the pinch ball 39a of the pressing portion 39 is placed on the next coin C2 following the coin C1 at the head, and the coin C2 is a spring member 39b. Is pressed downward by the urging force (see FIG. 10). Specifically, the coin C2 between the turntable 24 and the pinch ball 39a is pressed toward the turntable 24 with a force of about 100 g, for example, by the biasing force of the spring member 39b. As a result, the frictional force acting between the rubber member provided on the surface of the outer peripheral area 24c of the rotating disk 24 and the coin C2 increases, and the rotating disk 24 against the coin C2 pressed downward by the pinch ball 39a. The feeding force increases. For this reason, when the leading coin C1 is fed into the transport unit 40 by the feeding cam 28 of the feeding means 26, the next coin C2 continues to the leading coin C1 toward the movable member 35 of the regulating means 34. To move. In this way, the next coin C2 is pressed against the rubber member of the turntable 24 by the pressing portion 39 and gripped, so that the next coin C2 is reliably sent to the position of the movable member 35 of the regulating means 34 without stagnation. The feeding efficiency of the coins from the turntable 24 of the feeding means 22 to the transport unit 40 can be increased.

  The coins fed to the transport unit 40 by the feeding means 26 and transported by the transport unit 40 are identified by the identifying unit 50 such as denomination, true / false, and harm. Coins identified by the identification unit 50 are distributed for each denomination by each distribution means 60 based on the identification result by the identification unit 50. Coins sorted by each sorting means 60 are stored in each storage unit 68 for each denomination.

  This operation will be described in more detail. The coins identified by the identification unit 50 are continuously conveyed by the circulation belt 42 of the conveyance unit 40, and the sorting means 60 (for example, corresponding to the denomination of the coins) When the coin is detected by the coin detection sensor 64a of the sorting means 60a), the sorting plate 62a is driven, and the sorting plate 62a opens upward from the opening of the transport surface 45 of the transport unit 40. As a result, the coin enters the opening of the transport surface 45 and falls downward due to its own weight, thereby being sent to the storage unit 68 corresponding to the sorting means 60a.

  Here, since the detection sensitivity of the light receiving unit 64r of the coin detection sensor 64a is sweeter (easier to detect) than the detection sensitivity of the light receiving unit 38r of the feeding detection sensor 38, it is detected as a coin by the feeding detection sensor 38. When it is done, the malfunction that the said detection target is not detected as a coin in the coin detection sensor 64a is avoided. That is, when it is detected as a coin by the feeding detection sensor 38, it is guaranteed that the detection target is always detected as a coin by the coin detection sensor 64a.

  This is effective when, for example, a translucent foreign substance is mixed in the coin processing unit 10.

  For example, some toy coins are translucent resinous (transparent coins), and when such foreign matter is mixed in the coin processing unit 10, the feeding detection sensor 38 which is an optical sensor and The coin detection sensor 64a is more likely to cause erroneous detection. For example, in order to reliably determine that a translucent foreign object has passed (or reached), a light-shielding state is reliably determined. If the coin arrival (or arrival) "is set to a high value, even if a slight shading state occurs due to dust or the like, it may be erroneously detected as" coin passage (or arrival) ". Will increase. On the other hand, if the threshold value of the amount of light received for detecting “the passage (or arrival) of coins” (when “the amount of received light does not reach it”, “recognition (or arrival) of coins” is identified) is set low. In the state where a semi-transparent foreign matter is interposed, it cannot be determined that the light is blocked. Moreover, the trouble that the transparent coin mixed in one of the storage units without being detected at the time of depositing is paid out at the time of withdrawal may occur.

  However, according to the present embodiment, the detection sensitivity of the light receiving unit 64r of the coin detection sensor 64a is sweeter (easier to detect) than the detection sensitivity of the light receiving unit 38r of the feed detection sensor 38, so that the feed detection is performed. When it is detected as a coin by the sensor 38 and sent to the transport unit 40, the detection target is always detected as a coin also in the coin detection sensor 64a. If it is determined or nothing is identified), it is appropriately sorted as reject coins. Therefore, it is appropriately prevented that the “counting error” occurs in the coin processing unit 10.

  Even if a semi-transparent foreign substance tries to pass through the detection position of the feeding detection sensor 38, as described above with reference to FIG. 5, the feeding cam 28 of the feeding means 26 is used unless the feeding detection sensor 38 detects the passage of a coin. Keeps stopped. That is, coins are not fed. Therefore, it is preferable to check whether or not a semi-transparent foreign matter that is not identified as a coin by the feeding detection sensor 38 is blocking the detection position by the feeding detection sensor 38, and further, by the feeding detection sensor 38. When a translucent foreign object that cannot be identified as a coin blocks the detection position of the feeding detection sensor 38, the feeding cam 28 of the feeding means 26 is preferably driven in reverse. Alternatively, when coins are not paid out for a predetermined time, it is determined that a translucent foreign matter that is not determined as a coin by the feed detection sensor 38 is blocking the detection position by the feed detection sensor 38. Alternatively, the feed cam 28 of the feed means 26 may be driven in reverse.

  Further, as described above, the pressing portion 66a is disposed slightly upstream from the coin detection sensor 64a in the coin conveyance direction. As a result, when the coin pushed and conveyed by the projection 44 provided on the circulation belt 42 reaches a position below the pinch ball 66p, the coin pushes the pinch ball 66p upward, and the coin is It passes through the area between the conveyance surface 45 and the pinch ball 66p. At this time, the coin is pressed downward by the urging force of the spring member 66q.

  If such a pressing portion 66a is not provided, the coin is not pushed from the rear by the projection 44 of the circulation belt 42 on the conveyance surface 45 of the conveyance unit 40, but precedes the projection 44. When this happens, the coin is detected earlier than the original by the coin detection sensor 64a, and the timing at which the sorting plate 62a opens upward from the opening of the transport surface 45 of the transport unit 40 is also accelerated. For this reason, another coin in front of this coin may mistakenly enter the opening of the transport surface 45, and a sorting error may occur. On the other hand, when the pressing portion 66a is provided, as shown in FIG. 12A, the coin C is not pushed from behind by the projection 44 of the circulation belt 42 on the conveying surface 45 of the conveying portion 40. Even if the projection 44 is preceded, as shown in FIG. 12B, when the coin C comes into contact with the pinch ball 66p of the pressing portion 66a, the coin C is inserted by the pinch ball 66p. Be stopped. Then, as shown in FIG. 12 (c), when the protrusion 44 of the circulation belt 42 catches up with the coin C and the coin C is pushed rightward in FIG. 12 by the protrusion 44, the coin C causes the pinch ball 66p. Is pushed upward, and the coin C passes through the region between the conveying surface 45 and the pinch ball 66p. For this reason, when a coin is detected by the coin detection sensor 64a of the sorting means 60a, the coin is pushed by the protrusion 44 of the circulation belt 42 and does not precede the protrusion 44. In this way, a sorting error by the sorting means 60a can be prevented.

  Moreover, in the coin processing unit 10 of this Embodiment, the presence or absence of each protrusion part 44 provided in the circulation belt 42 of the conveyance part 40 is detected by the protrusion part detection sensor 52, and the control part 70 is a protrusion part detection sensor. Based on the detection information of each protrusion 44 by 52, the coin feeding operation by the feeding means 26 is controlled. This will be described in detail below.

  As described above, when the circulation belt 42 of the transport unit 40 is circulated in the counterclockwise direction in FIG. 2, the presence or absence of each protrusion 44 provided on the circulation belt 42 is shown in FIG. It is detected by a simple protrusion detection sensor 52. That is, the protrusion detection sensor 52 has a light emitting part 52a and a light receiving part 52b, and the light emitted from the light emitting part 52a is received by the light receiving part 52b, but provided on the circulation belt 42. When the protruding portion 44 reaches a position between the light emitting portion 52a and the light receiving portion 52b, the light emitted from the light emitting portion 52a is blocked by the protruding portion 44 and does not reach the light receiving portion 52b. Thus, the protrusion detection sensor 52 detects that the protrusion 44 is provided on the circulation belt 42, in other words, that the protrusion 44 is not missing from the circulation belt 42.

  Such an operation for detecting the presence or absence of each protrusion 44 in the circulation belt 42 may be performed before the coin processing unit 10 processes a coin, or during the processing of a coin by the coin processing unit 10. May be done. When detecting the presence or absence of each projection 44 in the circulation belt 42 before processing the coins by the coin processing unit 10, the circulation belt 42 is made while moving at a lower speed than when the coins are actually processed. 2 is circulated and moved counterclockwise in FIG. 2, and the presence or absence of each protrusion 44 is detected by the protrusion detection sensor 52 while the circulation belt 42 makes one turn. Information of detection of each protrusion 44 by the protrusion detection sensor 52 is stored in the storage unit 72. The control unit 70 controls the coin feeding operation by the feeding cam 28 of the feeding unit 26 based on the detection information of each protrusion 44 stored in the storage unit 72. Here, when the operation of detecting the presence or absence of each protrusion 44 in the circulation belt 42 is performed before the coin processing unit 10 processes the coin, the movement speed of the circulation belt 42 can be slowed down, so that the protrusion Even if the detection sensor 52 has a relatively low performance, the presence or absence of each protrusion 44 can be reliably detected.

  On the other hand, when detecting the presence / absence of each protrusion 44 in the circulation belt 42 during the processing of coins by the coin processing unit 10, the protrusion detection sensor 52 determines the presence / absence of each protrusion 44 over time. Based on the detection information of each protrusion 44 detected over time, the control unit 70 controls the coin feeding operation by the feeding cam 28 of the feeding unit 26 (in other words, in real time). Even in this case, the detection information of each projection 44 by the projection detection sensor 52 may be stored in the storage unit 72.

  A method of controlling the coin feeding operation by the control unit 70 will be described with reference to FIG.

  FIG. 13 is a time chart showing a detection state by the protrusion detection sensor 52 and the rotating plate phase detection sensor 48 and an operation state of the feeding cam 28 in the coin processing unit 10 shown in FIG. As shown in FIG. 13, when the protrusion 44 of the circulation belt 42 is detected by the protrusion detection sensor 52, the control unit 70 has passed a predetermined time (time indicated by reference symbol A in FIG. 13). After that, the feeding cam 28 of the feeding means 26 is operated from the stopped state, and is rotated in the counterclockwise direction in FIG. Thereby, the coin feeding operation to the circulation belt 42 of the transport unit 40 by the feeding cam 28 is performed. On the other hand, when the projection 44 falls off from the circulation belt 42 and the projection 44 that should originally be is not detected by the projection detection sensor 52, the control unit 70 stops the feeding cam 28 of the feeding means 26. The operation of feeding coins to the transport unit 40 is not performed. If coins are also fed to the part of the circulating belt 42 where the protrusions 44 have fallen off, two coins are chained between the two protrusions 44 that sandwich the part of the falling belts. This is because the coins transported by 42 cannot be properly sorted by the sorting means 60. As described above, when the protrusion 44 is removed from the circulation belt 42 by directly detecting the protrusion 44 of the circulation belt 42 by the protrusion detection sensor 52, the protrusion detected by the protrusion detection sensor 52 is detected. The missing information of the section 44 can be immediately reflected in the operation of the feeding cam 28 of the feeding means 26.

  Further, in the coin processing unit 10 as shown in FIG. 2, the rotational phase of a rotary plate (not shown) attached to the rotary shaft of the pulley 46 that stretches the circulation belt 42 is detected by the rotary plate phase detection sensor 48 (FIG. 4). As shown in FIG. 13, even if the protrusion 44 has fallen off from the circulation belt 42, the detection information by the rotating plate phase detection sensor 48 does not change. For this reason, simply detecting the rotational phase of the rotating plate by the rotating plate phase detection sensor 48 cannot automatically cope with the coin processing unit 10 when the protrusion 44 has fallen off from the circulation belt 42. Since a machine error occurs, it is necessary to stop the entire coin processing unit 10.

  Moreover, in the money depositing and dispensing machine 1 according to the present embodiment, the control unit 70 may serve as an output unit that outputs this information when the projection detection sensor 52 detects the lack of one or more projections 44. It is supposed to function. Information output by the control unit 70 is displayed on the operation display unit 74, printed by the printing unit 78, or transmitted to the external device 82 via the interface 80. When the information output by the control unit 70 is displayed on the operation display unit 74, information indicating that the protrusion 44 is missing while displaying information on the deposit process being executed on the operation display unit 74. By displaying it on a part of the screen of the operation display unit 74, both types of information can be notified to the operator. Moreover, when transmitting the information output by the control part 70 to the external device 82 via the interface 80, this external device 82 is a terminal operated by the administrator in the facility where the money depositing / dispensing machine 1 is installed. It may be a device or a terminal device installed in a maintenance center other than the facility.

  As described above, according to the coin processing unit 10 and the coin processing method of the present embodiment, the operation of feeding the coins fed out by the feeding means 22 (specifically, the rotating disk 24) to the transport unit 40 is regulated. The regulating means 34 (specifically, the movable member 35) and the feeding means 26 (specifically, the feeding cam 28) for receiving the coins fed by the feeding means 22 and feeding them to the transport unit 40 are provided. The feeding means 26 feeds coins to the transport unit 40 against the regulation by the regulating means 34. Thus, even if the feeding cam 28 of the feeding means 26 starts to rotate from the stop state as shown in FIG. 5, the leading coin C1 is fed to the circulation belt 42 of the transport section 40 by the movable member 35 of the regulating means 34. Is regulated. Then, as shown in FIG. 6, the coin C1 at the head is pushed to the circulation belt 42 of the transport unit 40 only when it is pushed from the rear by the protrusion 30 of the feeding cam 28 against the regulation of the regulation means 34. It is sent. For this reason, the next coin C2 does not bite into the gap between the projection 30 of the feeding cam 28 and the guide member 32. In this way, when coins are fed from the storage unit 20 to the transport unit 40, troubles such as coin biting between the feeding cam 28 of the feeding unit 26 and the guide member 32 are prevented. Therefore, the coin feeding speed can be increased.

  Moreover, in the coin processing unit 10 of the present embodiment, the movable member 35 of the restricting means 34 has a stop position (see FIGS. 5 and 6) for stopping the coins, and the coins to the transport unit 40 by the feeding means 26. The movable member 35 is pushed by the coin and allowed from the stop position when coins are fed into the transport unit 40 by the feeding means 26. Move to the position. The movable member 35 is provided with an urging mechanism 36a such as a torsion spring that urges the movable member 35 so that the movable member 35 is positioned at the stop position when no force is applied to the movable member 35.

  Further, in the coin processing unit 10 of the present embodiment, the pressing portion 39 that presses the coin in the vicinity of the outer peripheral edge of the turntable 24 of the feeding means 22 downward toward the turntable 24 is a feed cam 28 of the feed means 26. It is provided in the vicinity. In this case, the pressing unit 39 presses the next coin C2 against the rubber member on the surface of the outer peripheral edge region 24c of the rotating disk 24 to grip it, thereby reliably restricting the next coin C2 without stagnation. Thus, the feeding efficiency of the coins from the rotating disk 24 of the feeding means 22 to the transport unit 40 can be increased.

  Moreover, according to the coin processing unit 10 and the coin processing method of the present embodiment, the protrusion detection sensor that detects the presence or absence of each protrusion 44 such as a pin provided on the circulation belt 42 (moving member) of the transport unit 40. 52 is provided, and the control unit 70 controls the coin feeding operation by the feeding cam 28 of the feeding means 26 based on the detection information of each projection 44 by the projection detection sensor 52. As a result, when the projection 44 falls off from the circulation belt 42 and the projection 44 that should originally be detected is not detected by the projection detection sensor 52, the control unit 70 moves the feeding cam 28 of the feeding means 26. The stop state is maintained, and the coin feeding operation to the transport unit 40 is not performed. As described above, even when the protrusion 44 has fallen off from the circulation belt 42, the coin processing is continued by preventing the coins from being fed by the feeding means 26 to the portion of the circulation belt 42 where the protrusion 44 is missing. Will be able to. For this reason, the conveyance speed of the coin in the conveyance part 40 can be enlarged. In particular, when the protrusion 44 is removed from the circulation belt 42 by directly detecting the protrusion 44 of the circulation belt 42 by the protrusion detection sensor 52, the protrusion 44 detected by the protrusion detection sensor 52. This missing information can be immediately reflected in the operation of the feeding cam 28 of the feeding means 26.

  In the coin processing unit 10 according to the present embodiment, a storage unit 72 that stores detection information of each projection 44 by the projection detection sensor 52 is provided, and the control unit 70 stores each information stored in the storage unit 72. Based on the detection information of the protrusion 44, the coin feeding operation by the feeding means 26 may be controlled.

  Moreover, in the coin processing unit 10 of this Embodiment, before processing a coin by the coin processing unit 10, the protrusion part detection sensor 52 of each protrusion part 44 is moved by moving the circulation belt 42 of the conveyance part 40. The presence or absence may be detected in advance. In this case, when detecting the presence or absence of each protrusion 44 by the protrusion detection sensor 52 in advance, even if the moving speed of the circulation belt 42 is made lower than when coins are actually processed by the coin processing unit 10. Good.

  Alternatively, in the coin processing unit 10 of the present embodiment, when the coin processing unit 10 processes a coin, the protrusion detection sensor 52 determines the presence or absence of each protrusion 44 over time (in other words, in real time). The detection and control unit 70 may control the coin feeding operation by the feeding means 26 based on the detection information of each protrusion 44 detected over time.

  Further, in the coin processing unit 10 of the present embodiment, the control unit 70 functions as an output unit that outputs this information when the projection detection sensor 52 detects the lack of one or more projections 44. It is like that.

  In addition, the coin processing unit 10 and the coin processing method in this Embodiment are not limited to said aspect, A various change can be added.

  For example, as a restricting means for restricting an operation in which the coins fed by the feeding means 22 such as the turntable 24 are sent to the transport unit 40, a movable member 35 as shown in FIG. It is not limited to the thing of such a structure. As a restricting means, any means other than the one shown in the drawings can be used as long as it can stop the coins fed by the rotary disk 24 of the feeding means 22 or can act to resist the movement of the fed coins. The thing of the structure of can be used. For example, as a restricting means, a reverse rotation roller is arranged on the upper surface of the passage between the guide members 32, 33, and the coins fed by the feeding means 22 such as the rotating disk 24 are sent to the transport unit 40 by such a reverse rotation roller. May be restricted.

  Further, the feeding means for feeding coins against the regulation by the regulation means 34 is not limited to the configuration of the feeding cam 28 provided with the three protrusions 30 as shown in FIG. . Any other means than the one shown in the drawings can be used as long as it can receive the coins fed by the feeding means 22 and feed the received coins against the regulation by the regulation means 34 as the feeding means. The thing of the structure of can be used. For example, a feeding roller may be disposed above the conveyance surface, and the feeding roller may be driven intermittently.

  Further, each protrusion 44 provided on the circulation belt 42 of the transport unit 40 is not limited to the pin attached to the circulation belt 42. As another example, each protrusion 44 may be formed integrally with the circulation belt 42, or the protrusion 44 as a plate-like member may be attached to the circulation belt 42.

  Further, in the above-described aspect, an example in which a rotating plate (not shown) is provided on the rotating shaft of the pulley 46 and the phase of the rotating plate is detected by the rotating plate phase detection sensor 48 has been described. Installation of such a rotating plate or rotating plate phase detection sensor 48 may be omitted.

  Further, as the feeding means 22, a configuration other than the rotating disk 24 (for example, a feeding belt) may be used. Further, as the protrusion 44 of the circulation belt 42, a structure in which a pin is erected on the circulation belt 42 may be used. Alternatively, the protrusion 44 may be integrally formed with the circulation belt 42. As another example, an individual protrusion member may be attached to the circulation belt 42 as the protrusion 44 of the circulation belt 42. Further, instead of using the circulation belt 42 as the moving member in the transport unit 40, a chain or other member connected to a plurality of members may be used as the moving member.

  Moreover, as the pressing part 39, you may use things other than the structure containing the pinch ball 39a and the spring member 39b. For example, as the pressing portion 39, a projection made of an elastic member provided on the ceiling surface of the passage may be used. Moreover, you may use things other than the structure containing the pinch ball 66p and the spring member 66q as the pressing parts 66a and 66b. For example, as the pressing portions 66a and 66b, those provided with protrusions made of an elastic member on the ceiling surface of the passage may be used.

  Further, in the coin processing unit 10 of the present embodiment, the detection sensitivity of the light receiving unit 64r of the coin detection sensor 64a is higher (easy to detect) than the detection sensitivity of the light receiving unit 38r of the feeding detection sensor 38. However, there is no difference in the performance of the light receiving unit 64r and the light receiving unit 38r, and the detection sensitivity of the coin detection sensor 64a is made higher than the detection sensitivity of the feeding detection sensor 38 by changing the light emission amounts of the light emitting unit 64e and the light emitting unit 38e. You may keep it.

  Further, as the coin detection sensor 64a and the feeding detection sensor 38, those that realize a predetermined sensitivity difference may be selected and used in advance, but it is preferable to use a sensor capable of adjusting sensitivity for either one or both. . In that case, the sensitivity of each sensor can be appropriately adjusted according to the actual usage situation.

  The invention in which a predetermined sensitivity difference is provided between the coin detection sensor 64a and the feeding detection sensor 38 is also effective in a configuration without the feeding cam 28. For example, as shown in FIG. 16, a feeding belt 91 is used instead of the turntable 24, a stop pin 92 that is solenoid driven instead of the feeding cam 28, and a normal belt 93 instead of the circulating belt 42 with the pin. This is also effective in the provided configuration. In FIG. 16, 94 is a reverse rotation roller. When the fed coin is detected by the feeding detection sensor 38 and a predetermined condition is satisfied, the stop pin 92 is retracted and the coin is fed to the transport unit. When it is identified by the identifying unit 50 and detected by the corresponding coin detection sensor 64a, it is sorted. In addition, since the transparent coin which is not detected by the coin detection sensor 64a is not detected by the feeding detection sensor 38, the stop pin 62 is not retracted and is not sent to the transport unit. In this configuration, “regulatory means” is not provided.

  In addition, it is preferable that a residue detection sensor is provided in a region on the turntable 24 that is a coin accumulation unit. For example, if a residue detection sensor detects the presence of a residue in a situation where coins are not paid out for a predetermined time, only foreign matters that are not identified as coins are present in the area on the rotating disk 24. Means. In that case, it is preferable that abnormality notification is made. As the residue detection sensor, for example, a light-shielding sensor of a type that irradiates light from the side surface (from the radial direction) with respect to a coin passage route may be used. Such a light-shielding sensor can determine the presence of a completely transparent toy coin.

  Moreover, although the above description is made | formed about the money depositing / withdrawing machine 1, the coin processing unit 10 of this Embodiment is applicable also to a coin change machine as shown in FIG. In FIG. 17, the code | symbol 16 has shown the coin payment exit.
