The direction of the fibers of the wrapping paper supplied by the wrapping paper supply unit 50 may be along the axial direction of the accumulated coins.

  As shown in FIGS. 2 and 3, the wrapping paper supply unit 50 includes a wrapping paper supply roll 51 around which a wrapping wrapping paper is wound, and the wrapping-like packaging unwound from the wrapping paper supply roll 51. The paper passes between the pair of guide rollers 52 and 53 and is guided to the packaging region 41 of the packaging unit 40 by the packaging paper guide member 54. Further, in the vicinity of the wrapping paper guide member 54, a belt-like wrapping paper sent to the wrapping paper guide member 54 from between the pair of guide rollers 52, 53 is set to a predetermined length (specifically, 2 of the accumulated coins). A cutting member 58 made of, for example, a cutter or the like is provided. The cutting member 58 allows the wrapping paper to be sent to the packaging region 41 of the packaging unit 40 to have a predetermined length. It is designed to be disconnected.

  A wrapping paper guide member 55 for guiding the wrapping paper sent from the wrapping paper guide member 54 to the wrapping area 41 of the wrapping section 40 is provided in the vicinity of the wrapping area 41 of the wrapping section 40. The wrapping paper guide member 55 can reciprocate along a horizontal plane. More specifically, the wrapping paper guide member 55 is positioned so as to block a side opening portion of the wrapping region 41 (specifically, a side opening portion between the wrapping roller 42a and the wrapping roller 42b). 2) and a retracted position (see FIG. 3) that retracts from the side opening portion of the packaging area 41 and opens the side opening portion (see FIG. 3), as shown in FIG. In addition, the wrapping paper is guided to the wrapping area 41 when the wrapping paper guide member 55 is located at the advanced position.

  Further, wrapping paper guide members 56a, 56b, and 56c are provided in the vicinity of the wrapping rollers 42a, 42b, and 42c around the wrapping area 41, and the wrapping guided to the wrapping area 41 by the wrapping paper guide member 55. The paper is guided by these wrapping paper guide members 56a, 56b, and 56c so as to be wound around the circumferential surface of the accumulated coins. Here, of the three wrapping paper guide members 56a, 56b, and 56c, the two wrapping paper guide members 56a and 56c are fixed at positions corresponding to the denominations of coins. The wrapping paper guide member 56b located in the open portion can reciprocate along a horizontal plane. More specifically, the wrapping paper guide member 56b is advanced from the side opening portion of the packaging region 41 (see FIG. 2) and retracted from the side opening portion of the packaging region 41. 2 when the wrapping paper guide member 56b is located at the advanced position as shown in FIG. The wrapping paper guided to the wrapping area 41 is guided to be wrapped around the circumferential surface of the accumulated coins by the wrapping paper guide members 56a, 56b, 56c.

  Next, the detail of the structure of the winding mechanism 60 which winds up the upper and lower end parts of the wrapping paper wound around the accumulated coins and crimps the upper and lower end surfaces of the accumulated coins will be described. The winding mechanism 60 includes a pair of upper and lower saddle-shaped winding needles 61 and a winding needle moving means 62 that moves the pair of upper and lower winding needles 61. As shown in FIG. 1, the winding needle moving means 62 has a pair of upper and lower support bodies 62 a that respectively support a pair of upper and lower winding needles 61. The pair of upper and lower support bodies 62a are respectively attached to the tips of a pair of upper and lower arms 62b, and these pair of upper and lower arms 62b are supported so as to be slidable in the vertical direction with respect to the swing frame 62c. Here, the pair of upper and lower arms 62b are biased in a direction approaching each other by, for example, a spring (not shown).

  The swing frame 62c is formed in a substantially U-shape in which the upper and lower edges are bent, and a plurality of slide shafts 62d are attached between the upper and lower edges of the swing frame 62c. A pair of upper and lower arms 62b are attached to these slide shafts 62d so as to be slidable in the vertical direction. The swing frame 62c is supported so as to be horizontally pivotable about a pivot shaft 62e penetrating the upper and lower edges of the swing frame 62c, and a pair of upper and lower windings by, for example, a spring (not shown). The telescoping needle 61 is urged to rotate in a direction approaching the packaging region 41 of the packaging unit 40.

  A cam shaft 64 provided with a pair of upper and lower cams 64a is disposed in the vicinity of the swing frame 62c, and a pair of upper and lower arms 62b are moved in the vertical direction corresponding to each cam 64a. A pair of upper and lower levers 64b is provided. The cam shaft 64 is rotated by a cam shaft driving motor 65 (see FIG. 9) so as to rotate once when one wrapping coin is created in the packaging process. The base end of each lever 64b is pivotally supported by a support shaft 64c that is fixed in position and extends in the horizontal direction, and each lever 64b can swing in the vertical direction about the support shaft 64c. A cam roller 64d that contacts each cam 64a is attached to an intermediate portion of each lever 64b. Further, a push roller 64e that is in contact with each arm 62b is attached to the tip of each lever 64b. In the upper lever 64b of the pair of upper and lower levers 64b, the upper cam roller 64d is in contact with the upper surface of the upper cam 64a, and the upper push roller 64e is in contact with the lower surface of the upper arm 62b. Thus, the lowering of the upper arm 62b biased downward is restricted. On the other hand, in the lower lever 64b of the pair of upper and lower levers 64b, the lower cam roller 64d is brought into contact with the lower surface of the lower cam 64a, and the lower push roller 64e is placed on the upper surface of the lower arm 62b. By abutting, the rise of the lower arm 62b biased upward is restricted. Then, by one rotation of the cam shaft 64 in the packaging process, the pair of upper and lower levers 64b swings as the pair of upper and lower cams 64a rotate. As a result, the pair of upper and lower arms 62b move in the vertical direction, and thus the pair of upper and lower winding needles 61 also move in the vertical direction.

  Further, a cam 64f is attached to the cam shaft 64, and a cam roller 66 (see FIGS. 2 and 3) capable of contacting the cam 64f is attached to the swing frame 62c. When the cam 64f pushes the cam roller 66, the pair of upper and lower winding needles 61 are retracted from the packaging region 41 of the packaging unit 40 as shown in FIG. On the other hand, during the period in which the cam 64f does not push the cam roller 66 during one rotation of the cam shaft 64 in the packaging process, as shown in FIG. 3, the oscillating frame 62c is biased by a spring (not shown) or the like. A pair of upper and lower winding needles 61 advances into the packaging region 41 of the packaging unit 40 and enables the wrapping operation of the wrapping paper.

  The cam shaft 64 controls the operation of each mechanism of the coin wrapping apparatus 10 so as to create one wrapping coin by one rotation. In addition to the cam 64a and the cam 64f described above, for example, A cam for controlling the movement of the wrapping roller 42b, a cam for controlling the movement of the support rod 71 of the stacked coin transport section 70, a cam for controlling the movement of the wrapping paper guide member 55 and the wrapping paper guide member 56b, etc. A plurality of cams are attached.

  A functional block diagram of the coin wrapping apparatus 10 according to the present embodiment is shown in FIG. The coin wrapping apparatus 10 according to the present embodiment has a control unit 90 that controls each component of the coin wrapping apparatus 10. Specifically, the feeding unit 12, the conveying unit 20, the drive motor 48, the wrapping paper supply unit 50, the camshaft drive motor 65, and the like are connected to the control unit 90, and the control unit 90 includes these feeding units. 12, these components are controlled by sending command signals to the transport unit 20, the drive motor 48, the wrapping paper supply unit 50, the camshaft drive motor 65, and the like. In addition, a detection sensor 83, a passage detection sensor S1, and a counting sensor S2 are connected to the control unit 90, and detection information by these sensors is sent to the control unit 90.

  In addition, the stacking failure detection unit 92 is connected to the control unit 90, and the stacking failure detection unit 92 allows the stacked coin transfer unit 70 to transfer the stacked coins from the stacking unit 30 to the packaging unit 40. Based on the position of a specific part of the accumulated coin (specifically, for example, the uppermost coin), it is detected whether or not an accumulation failure has occurred in the accumulated coin formed by the accumulation unit 30. It has become. In addition, as shown in FIG. 7, an accumulation failure occurs in the accumulated coins formed by the accumulation unit 30, as shown in FIG. 7, some coins in the accumulated coins between the support rod 71 and the coin pressing member 74. Can be exemplified as a phenomenon where the camera stands without being in a horizontal state. In addition, the stacking failure of the accumulated coins in the present invention is not limited to the aspect of FIG. A method for detecting whether or not there is a stacking failure of the accumulated coins by the stacking failure detection means 92 will be described later.

  Further, a notification unit 94 is connected to the control unit 90, and when the stacking failure detection means 92 detects that a stacking failure has occurred in the accumulated coins, this is notified by the notification unit 94 to the operator. To be notified. Specifically, for example, the notification unit 94 includes a monitor, and a warning is displayed on the monitor when the stacking defect detection unit 92 detects that stacking defects have occurred in the accumulated coins. Yes. Note that the notification unit 94 is not limited to the one that visually notifies the operator using a monitor, but instead may be configured to notify the operator audibly by voice or the like. As will be described later, if it is detected that an accumulation failure of the accumulated coins has occurred, it is not necessary to display a warning on the monitor if the accumulated coins are rejected.

  Next, the operation of the coin wrapping apparatus 10 having such a configuration, specifically, a coin wrapping method by the coin wrapping apparatus 10 will be described. The operation of the coin wrapping apparatus 10 as described below is performed by the control unit 90 controlling each component of the coin wrapping apparatus 10.

  The loose coins received on the rotating disk 14 of the feeding unit 12 are fed one by one to the transport path 21 of the transport unit 20 by the feeding unit 12. Then, in the stacking unit 30, the coins sent from the transport path 21 of the transport unit 20 to the stacking region 31 of the stacking unit 30 are the lowest layer among a plurality of coins that have already been stacked in the stacking region 31. The coins are sequentially accumulated from the lower side to the upper side. When coins corresponding to the number of packaging units are accumulated in the accumulating unit 30, the accumulated coins are raised to a predetermined packaging position in the packaging unit 40 by the accumulated coin transport unit 70.

  Thereafter, the wrapping paper is supplied to the packaging region 41 of the wrapping unit 40 by the wrapping paper supply unit 50, and the wrapping paper is wound around the accumulated coins in the wrapping unit 40. Specifically, in the packaging unit 40, the cam shaft 64 rotates once every time one wrapping coin is produced, and is accumulated by the three packaging rollers 42a, 42b, and 42c during one rotation of the cam shaft 64. The wrapping paper supplied from the wrapping paper supply roll 51 of the wrapping paper supply unit 50 and cut into a predetermined length by the cutting member 58 is collected with the three wrapping rollers 42a, 42b, and 42c while the coins are sandwiched and rotated. Supply between coins. When the wrapping paper is supplied to the wrapping region 41 of the wrapping unit 40 by the wrapping paper supply unit 50, the wrapping paper guide members 55 and 56b are arranged on the side of the wrapping region 41 of the wrapping unit 40 as shown in FIG. It is located at the advancing position that closes the open side. At this time, the winding needle 61 of the winding mechanism 60 is located at a retracted position so as to retract from the packaging region 41 of the packaging unit 40.

  After that, as shown in FIG. 3, the wrapping paper guide members 55 and 56 b are moved to the retracted position so as to open the side opening portion of the packaging region 41 of the packaging unit 40, and the winding needle 61 of the winding mechanism 60. Is moved to the advance position where it advances into the packaging area 41 of the packaging unit 40. After the winding needle 61 of the winding mechanism 60 moves to the advance position so as to advance into the packaging area 41 of the packaging unit 40, the upper and lower ends of the wrapping paper wound around the circumferential surface of the accumulated coins are wound around the winding mechanism 60. Are wound by a pair of upper and lower winding needles 61 and crimped to both upper and lower end surfaces of the accumulated coin. When the caulking operation of both the upper and lower end surfaces of such an accumulated coin is completed, the pair of upper and lower winding needles 61 are retracted to the initial position, and then the space between the three wrapping rollers 42a, 42b, 42c is opened to remove the wrapping coins. Release downward.

  Further, in the present embodiment, while the accumulated coins are conveyed from the accumulation unit 30 to the packaging unit 40 by the accumulated coin conveyance unit 70, the position of a specific portion of the accumulated coins (specifically, for example, the uppermost coin). Based on the above, the stacking failure detection means 92 detects whether or not stacking failure has occurred in the stacked coins formed by the stacking unit 30. More specifically, the stacking failure detection unit 92 is configured to detect that the uppermost coin of the stacked coins is between the stacking position and the packing position after the stacked coin transport unit 70 starts transporting the stacked coins from the stacking position of the stacking unit 30. On the basis of the amount of movement of the accumulated coins until reaching a predetermined position, it is detected whether or not an accumulation defect has occurred in the accumulated coins. A specific method for detecting the occurrence of stacking failure of stacked coins by the stacking failure detection means 92 will be described below with reference to FIG.

  In FIG. 8, the stacking defect detecting means 92 is a predetermined position (indicated by reference symbol J) of the uppermost coin in the accumulated coins after the accumulated coins begin to be conveyed from the accumulation position of the accumulation unit 30 by the accumulated coin conveyance unit 70. This predetermined position is a position between the stacking position and the packaging position). Based on the movement amount of the stacked coins until reaching the stacking position, it is detected whether or not a stacking defect has occurred in the stacked coins. To do. Here, as shown in FIG. 8A, when no accumulation failure occurs in the accumulated coins formed by the accumulating unit 30, the accumulated coins are accumulated from the accumulation position of the accumulating unit 30 by the accumulated coin transport unit 70. 8 (b), the amount of movement of the accumulated coins from when the first coin is transported until the uppermost coin reaches the predetermined position J becomes K. In the case where stacking failure occurs in the accumulated coins formed by 30, the uppermost coin in the accumulated coins is predetermined after the accumulated coins begin to be conveyed from the accumulation position of the accumulation unit 30 by the accumulated coin conveyance unit 70. The amount of movement of the accumulated coins until reaching the position J is L smaller than K. For this reason, with respect to the coins of each denomination, the uppermost coin in the accumulated coins is moved to the predetermined position J after the accumulated coins in which the accumulation failure has not occurred are started to be conveyed from the accumulation position of the accumulation unit 30 by the accumulated coin conveyance unit 70. The amount of movement of the accumulated coins until reaching the value (the size indicated by the reference symbol K in FIG. 8A) is calculated in advance and set as a threshold value. When it is smaller than the set movement amount threshold, the stacking fault detection means 92 detects that a stacking fault has occurred in the accumulated coins.

  Here, the timing at which the uppermost coin in the accumulated coins conveyed by the accumulated coin conveyance unit 70 reaches the predetermined position indicated by the reference symbol J is based on the detection state of the detection plate 82 by the detection sensor 83. Yes. Specifically, the light emitted from the light emitting element 83a of the detection sensor 83 is blocked by the detection plate 82 provided on the coin pressing member 74 and does not reach the light receiving element 83b, or emitted from the light emitting element 83a. It is detected that the uppermost coin of the accumulated coins has reached the predetermined position J when the received light is blocked by the detection plate 82 and then enters a light-transmitting state again and reaches the light receiving element 83b. It has become. Here, when the denominations of the accumulated coins are 1 yen, 5 yen, and 10 yen, the light emitted from the light emitting element 83a of the detection sensor 83 is shielded by the detection plate 82 provided on the coin pressing member 74. When the light receiving element 83b is not reached, it is detected that the uppermost coin in the accumulated coins has reached the predetermined position J, whereas the denomination of the accumulated coins is 50 yen, 100 In the case of a circle or 500 yen, the light emitted from the light emitting element 83a is blocked by the detection plate 82 and then enters the light transmitting state again and reaches the light receiving element 83b. It is detected that the coin has reached the predetermined position J. Accumulated coins with denominations of 50 yen, 100 yen, and 500 yen are larger in the accumulation direction than accumulated coins with denominations of 1, 5, 10, and 10 yen, so the former is smaller than the latter The predetermined position J is reached by the amount of movement, so it is better to shift the determination timing as to whether or not there is a stacking defect as much as possible. This comes from the shape of the cam 64f before and after reaching the predetermined position J. Specifically, when only 49 sheets of 1 yen, 5 yen, and 10 yen are accumulated (one sheet is insufficient), the camshaft 64 is excessively moved to reach the predetermined position J as compared with the case where 50 sheets are accumulated. Assuming that the amount of rotation is A, when only 49 sheets of 50 yen, 100 yen, and 500 yen are accumulated, the camshaft 64 rotates more by the time it reaches the predetermined position J than when 50 sheets are accumulated. Assuming that the amount of rotation to be moved is B, the relation of A> B is satisfied, that is, the resolution of 1 yen, 5 yen, and 10 yen is higher, so the determination time of 50 yen, 100 yen, and 500 yen Also, it is better to approach the judgment time of 1 yen, 5 yen and 10 yen.

  FIG. 10 is a timing chart showing the transition of the drive state of the camshaft drive motor 65, the detection result of the fixed position detection of the camshaft 64, and the detection result of the accumulation state detection of the accumulated coins in the coin wrapping apparatus 10 shown in FIG. It is. As described above, the support rod 71 that supports the stacked coins formed by the stacking unit 30 from below and pushes it upward is moved up and down in conjunction with the cam shaft 64. The cam shaft 64 is used in the packaging process. Thus, the camshaft drive motor 65 is rotated by the camshaft drive motor 65 so as to rotate once when one wrapping coin is produced. Then, as shown in the timing chart of FIG. 10, when the camshaft drive motor 65 starts to rotate forward from the stopped state, an optical sensor (not shown) that detects the rotation angle of the camshaft 64 changes from the light-shielded state to the light-transmitting state. As a result, the rotation angle of the cam shaft 64 becomes a predetermined magnitude (for example, 20 °), and it is detected that the cam shaft 64 has reached a fixed position (time T0). Further, when the camshaft 64 reaches a fixed position, the accumulated coins formed by the accumulation unit 30 start to rise by the support rod 71 of the accumulation coin transport unit 70.

  As shown in the timing chart of FIG. 10, when the denominations of the accumulated coins formed by the accumulation unit 30 are 1 yen, 5 yen, and 10 yen, light emitted from the light emitting element 83a of the detection sensor 83 is emitted. It is detected that the uppermost coin in the accumulated coins has reached a predetermined position J (see FIG. 8) at time T1 when the light is blocked by the detection plate 82 provided on the coin holding member 74 and does not reach the light receiving element 83b. It has become so. The uppermost coin in the accumulated coins from time T0 when the fixed position detection of the cam shaft 64 is changed from the light shielding state to the light transmitting state until time T1 when the accumulation state detection by the detection sensor 83 is changed from the light transmitting state to the light shielding state. When the movement amount is substantially equal to a preset movement amount threshold, the stacking fault detection means 92 detects that there is no stacking fault in the stacked coins formed by the stacking unit 30. On the other hand, the uppermost coin in the accumulated coins from the time T0 when the fixed position detection of the camshaft 64 is changed from the light shielding state to the light transmitting state to the time T1 when the accumulated state detection by the detection sensor 83 is changed from the light transmitting state to the light shielding state. When the movement amount is smaller or larger than a preset movement amount threshold, the stacking fault detection means 92 detects that a stacking fault has occurred in the stacked coins formed by the stacking unit 30. To do. Note that the movement amount of the uppermost coin in the accumulated coins is detected based on the number of rotation pulses of the camshaft drive motor 65.

  On the other hand, when the denominations of the accumulated coins formed by the accumulation unit 30 are 50 yen, 100 yen, and 500 yen, the light emitted from the light emitting element 83a of the detection sensor 83 is blocked by the detection plate 82. It is detected that the uppermost coin of the accumulated coins has reached a predetermined position J (see FIG. 8) at time T2 when the light is again transmitted and reaches the light receiving element 83b. The uppermost coin in the accumulated coins from time T0 when the fixed position detection of the cam shaft 64 is changed from the light shielding state to the light transmitting state until time T2 when the accumulation state detection by the detection sensor 83 is changed from the light shielding state to the light transmitting state. When the movement amount is substantially equal to a preset movement amount threshold, the stacking fault detection means 92 detects that there is no stacking fault in the stacked coins formed by the stacking unit 30. On the other hand, the uppermost coin in the accumulated coins from time T0 when the fixed position detection of the cam shaft 64 is changed from the light shielding state to the light transmitting state until time T2 when the accumulated state detection by the detection sensor 83 is changed from the light shielding state to the light transmitting state. When the movement amount is smaller or larger than a preset movement amount threshold, the stacking fault detection means 92 detects that a stacking fault has occurred in the stacked coins formed by the stacking unit 30. To do.

  Here, when the stacking failure detection means 92 detects that stacking failure has occurred in the stacked coins formed by the stacking unit 30, as shown in the flowchart of FIG. After stopping from the forward rotation state by applying a brake, the rotation state is reversed, and the camshaft 64 rotates in the reverse direction. As a result, the support rod 71 is lowered, and the accumulated coins supported by the support rod 71 return to the accumulation unit 30. Here, after the accumulated coins are returned to the accumulation unit 30, the accumulated coins may be conveyed again from the accumulation unit 30 to the packaging unit 40 by the accumulation coin conveyance unit 70. That is, in the case of the stacking failure as shown in FIG. 7, the stacking failure may be resolved while the stacked coins are being transported from the stacking unit 30 to the packaging unit 40. Moreover, as another aspect, when the accumulation coin is returned to the accumulation unit 30 after the accumulation defect detection unit 92 detects that the accumulation defect is generated in the accumulation coin formed by the accumulation unit 30. In addition, the accumulated coins returned to the accumulation unit 30 may be discharged downward and rejected by retracting the accumulation roller 36 of the accumulation unit 30 from the lower position of the packaging unit 40. In this case, after the returned accumulated coins are rejected, coins may be accumulated again by the accumulation unit 30.

  According to the coin wrapping apparatus 10 and the coin wrapping method of the present embodiment having the above-described configuration, the stacking failure detection unit 92 is configured to collect the accumulated coins while the accumulated coins are conveyed by the accumulated coin conveyance unit 70. Based on the position of the specific part (specifically, for example, the uppermost coin), it is detected whether or not a stacking defect has occurred in the stacked coins formed by the stacking unit 30. . Here, in the conventional coin wrapping apparatus, since the presence or absence of the stacking failure is detected after the packaging process is performed on the stacked coins by the wrapping unit, On the other hand, when the packaging process is performed, there is a problem that the coins are scattered or jammed. However, the coin wrapping apparatus 10 and the coin wrapping method of the present embodiment can prevent the occurrence of such a problem. it can. Also, compared to a method of detecting whether or not stacking failure has occurred in the accumulated coin by measuring the height of the accumulated coin, the accumulated coin is not moved by the height of the accumulated coin. However, since it is possible to detect whether or not a stacking defect has occurred in the accumulated coins by moving it only slightly, it is possible to detect a stacking defect in the accumulated coins in a shorter time and a stacking unit. It is possible to further reduce the space required for transporting the accumulated coins from 30 to the packaging unit 40 and detecting stacking failure in the accumulated coins.

  Further, in the coin wrapping apparatus 10 of the present embodiment, as described above, the wrapping unit 40 is disposed above the stacking unit 30, and the stacking failure detection unit 92 is connected to the stacking unit by the stacked coin transport unit 70. From when the accumulated coins start to be conveyed from the 30 accumulation positions until the specific portion of the accumulated coins (specifically, for example, the uppermost coin) reaches a predetermined position (a position indicated by reference symbol J in FIG. 8). Based on the amount of movement of the accumulated coins, it is detected whether or not an accumulation defect has occurred in the accumulated coins formed by the accumulation unit 30. Further, in this case, the stacking unit 30 is the lowest coin among the plurality of coins that have already been stacked in the stacking region 31 so as to be stacked in the stacking region 31. The coins are sequentially accumulated from the lower side to the upper side by dragging them into the lower side.

  Further, in the coin wrapping apparatus 10 of the present embodiment, as described above, the coin pressing member 74 that presses the coin on the uppermost layer of the stacked coins formed by the stacking unit 30 from above and the coin pressing member 74 are provided. A detection sensor 83 for detecting the detected plate 82 is provided. Here, the detection sensor 83 functions as a pressing member position detection unit that detects the position of the coin pressing member 74. The stacking failure detection means 92 detects the position of the detection plate 82 provided on the coin pressing member 74 by the detection sensor 83 after the stacked coin transport unit 70 starts transporting the stacked coins from the stacking position of the stacking unit 30. On the basis of the amount of movement of the accumulated coins up to this point, it is detected whether or not an accumulation failure has occurred in the accumulated coins formed by the accumulation unit 30. More specifically, the detection sensor 83 includes a light emitting element 83 a and a light receiving element 83 b, and the detection sensor 83 blocks light emitted from the light emitting element 83 a by a detection plate 82 provided on the coin pressing member 74. When the light does not reach the light receiving element 83b, or when the light emitted from the light emitting element 83a is blocked by the detection plate 82 and enters the light transmitting state again and reaches the light receiving element 83b. The specific part of the accumulated coins (specifically, for example, the uppermost coin) is detected to reach a predetermined position.

  Moreover, in the coin wrapping apparatus 10 of the present embodiment, as described above, the accumulated coin transport unit 70 is detected when the accumulation failure is detected in the accumulation coin by the accumulation failure detection unit 92. In addition, the accumulated coins being conveyed are returned to the accumulation unit 30. In this case, after the accumulated coins are returned to the accumulating unit 30 by the accumulated coin transport unit 70, the returned accumulated coins are excluded, and the accumulating unit 30 accumulates the coins again. Good. Further, after the accumulated coins are returned to the accumulating unit 30 by the accumulated coin conveying unit 70, the accumulated coins may be conveyed again from the accumulating unit 30 to the packaging unit 40 by the accumulated coin conveying unit 70. According to these matters, after eliminating the stacking failure of the stacked coins in the stacking unit 30, the stacked coins in which the stacking failure has not occurred are transported again from the stacking unit 30 to the packaging unit 40. It becomes possible to wrap up the accumulated coins.

  In addition, the coin wrapping apparatus 10 and the coin wrapping method according to the present embodiment are not limited to the above-described aspects, and various changes can be made.

  For example, in the coin wrapping apparatus 10, the packaging unit 40 is not limited to being provided above the stacking unit 30. The packaging unit 40 may be provided below the stacking unit 30. Further, as will be described later, the stacking failure detection means 92 is not during the time when the accumulated coins are conveyed by the accumulated coin conveyance unit 70 but during the time when the accumulated coins are formed by the accumulation unit 30. (Specifically, for example, based on the position of the uppermost coin), when the accumulation coin formed by the accumulation unit 30 detects whether or not a stacking defect has occurred. The stacking unit 30 and the packaging unit 40 may be provided adjacent to each other.

  In addition, the stacking unit 30 lowers the lowermost coin among the plurality of coins that are already stacked in the stacking region 31 so that the rose coins that have been transported to the stacking region 31 in the stacking unit 30 are stacked. However, the present invention is not limited to a configuration in which loose coins are sequentially accumulated from the lower side to the upper side by being pushed in. As another configuration of the stacking unit 30, the coins transported to the stacking region 31 in the stacking unit 30 are placed so as to be stacked on the uppermost coin among the plurality of coins already stacked in the stacking region 31. You may use what you do.

  In addition, the stacking failure detection unit 92 determines whether or not stacking failure has occurred in the stacked coins formed by the stacking unit 30 based on the position of the uppermost coin of the stacked coins as a specific portion of the stacked coins. It is not limited to what detects. That is, the specific part of the accumulated coins that is a reference for detection by the stacking defect detection means 92 is not limited to the uppermost coin, but the lowermost coin, the coin at the center in the vertical direction, or any other arbitrary coin It may be a coin at the position.

  Further, the stacking failure detection means 92 is a movement amount of the accumulated coins from when the accumulated coins start to be conveyed from the accumulation position of the accumulation unit 30 until the detection plate 83 provided on the coin pressing member 74 is detected by the detection sensor 83. It is not limited to what detects the presence or absence of the stacking fault in the said accumulation coin based on. As another aspect of the stacking failure detection means 92, for example, the accumulated coins based on the amount of movement of the accumulated coins until the support rod 71 reaches a predetermined position after the support rod 71 instead of the coin pressing member 74 starts to rise. It may be configured to detect whether or not a stacking fault has occurred.

  In addition, a plurality of different predetermined height levels may be set as the above-mentioned predetermined positions serving as a reference for detection by the stacking fault detection means 92. For example, in the case where two items having different height levels are set as the predetermined positions, a specific portion of the accumulated coins (specifically, for example, the uppermost coin) is set to the height level by the accumulated coin transport unit 70. Even when the stacking failure detection means 92 detects that stacking failure has occurred in the stacked coins when the first predetermined position is relatively small (that is, relatively low), The accumulated coin transport unit 70 continues to raise the packaging unit 40. Then, the specific portion of the accumulated coin has a second predetermined position (that is, the second predetermined position is accumulated higher than the first predetermined position) with a height level larger (that is, relatively higher) than the first predetermined position. When the stacking failure detection means 92 detects that no stacking failure has occurred in the stacked coins, the stacked coins are conveyed to the packaging unit 40. The wrapping unit 40 wraps the wrapping paper. According to such an aspect, even when the accumulated coins have reached the first predetermined position, even when it is detected by the accumulated defect detection means 92 that an accumulated defect has occurred in the accumulated coins, the accumulated coins In such a case, the accumulated coins may not be returned to the accumulating unit 30 once because the accumulation failure of the accumulated coins may be resolved before the first coin is conveyed from the first predetermined position to the second predetermined position. The entire processing time can be shortened by transporting to the packaging unit 40 as it is and packaging with the packaging unit 40. Further, if a stacking failure of the accumulated coins is detected even at the second predetermined position, the accumulated coins are once returned to the accumulating unit 30 and the same process as described above is performed.

  In addition, the stacking defect detection means 92 is not during the time when the accumulated coins are conveyed by the accumulated coin conveyance unit 70 but during the time when the accumulated coins are formed by the accumulation unit 30 (specifically, the specific portion of the accumulated coins (specifically, For example, based on the position of the uppermost coin), it may be detected whether or not a stacking defect has occurred in the stacked coin formed by the stacking unit 30. That is, based on whether or not the position of the coin on the uppermost layer of the accumulated coins in a state before the accumulated coins formed by the accumulating unit 30 are conveyed by the accumulated coin conveying unit 70 is a predetermined position, It may be configured to detect whether or not a stacking failure has occurred in the accumulated coins.

  Specifically, as described above, the stacking unit 30 stacks the loose coins that have been transported to the stacking region 31 of the stacking unit 30 so as to be stacked in the stacking region 31 as described above. The coins are sequentially accumulated from the lower side to the upper side by rolling the lower coins among the plurality of coins, and the accumulated coins formed by the accumulating unit 30 The coin in the uppermost layer is pressed from above by a coin pressing member 74. Then, the stacking defect detection unit 92 generates stacking defects in the stacked coins formed by the stacking unit 30 based on the position of the coin pressing member 74 while the stacked coins are formed by the stacking unit 30. The detection of whether or not there is. More specifically, the coin pressing member 74 is provided with a detection plate 82, and a detection sensor 83 for detecting the detection plate 82 is disposed at a fixed position. In addition, the height level of the detection sensor 83 is provided in the coin pressing member 74 that presses the stacked coins from above when the stacking coins formed by the stacking unit 30 have no stacking defects. The size is set such that the detection sensor 83 detects the detected plate 82 (that is, the detection sensor 83 is in a light-shielding state). Thus, when the detection plate 82 is detected by the detection sensor 83 when the stacked coins are formed by the stacking unit 30, the stacking failure detection means 92 is stacked by the stacking unit 30. When it is detected that no stacking failure has occurred in the coin, and the detection plate 82 is not detected by the detection sensor 83, the stacking failure detection means 92 is provided in the stacked coin formed by the stacking unit 30. It is detected that a stacking fault has occurred. Note that the height level of the detection sensor 83 may be set or changed in advance depending on the denomination of the accumulated coins formed by the accumulation unit 30.

  Even in the coin wrapping apparatus 10 having such an aspect, the accumulated coins are moved as compared with the method of detecting whether or not stacking failure has occurred in the accumulated coins by measuring the height of the accumulated coins. Since it is possible to detect whether or not a stacking failure has occurred in the accumulated coins, it is possible to detect the stacking failure of the stacked coins in a shorter time and from the stacking unit 30 to the packaging unit 40. It is possible to further reduce the space required for transporting the accumulated coins to and detecting the stacking failure in the accumulated coins.

  Further, in the coin wrapping apparatus 10 according to still another modified example, after the accumulated coins are conveyed from the accumulation unit 30 to the packaging unit 40 by the accumulated coin conveyance unit 70, the wrapping paper is sent from the wrapping paper supply unit 50 to the packaging unit 40. Without rotating each packaging roller 42a, 42b, 42c in the packaging part 40, the cam shaft 64 is rotated once by the cam shaft drive motor 65, and only the operation of the winding needle 61 of the winding mechanism 60 is performed. May be allowed to do. Then, after rotating the camshaft 64 once, the stacking roller 36 of the stacking unit 30 and the support rod 71 of the stacked coin transport unit 70 are retracted from the lower position of the packing unit 40 to the side, thereby being in the packing unit 40. The accumulated coins are discharged downward and rejected. When such an operation is performed, the height of the accumulated coins can be measured by operating the winding needle 61 of the winding mechanism 60, for example, coin wrapping for a new type of coin Even when the packaging process is performed by the apparatus 10, the coin packaging apparatus 10 can measure the height of the accumulated coins, and information on the new type of coins (for example, the thickness of the coins). Etc.) can be acquired by the operator.
