  As shown in FIGS. 7 to 9, the winding needle position adjusting unit 73 is provided so as to extend along a vertical direction with a drive motor 73a configured by a stepping motor and the like, a gear 73b rotated by the drive motor 73a, and the like. And a rack 73c having a plurality of teeth meshing with the teeth of the gear 73b, and a moving member 73d to which the drive motor 73a is attached and movable along the vertical direction. A winding member 71 provided with an upper winding needle 71a is attached to the member 73d. Here, the drive motor 73a is rotatable in both forward and reverse directions. When the gear 73b is rotated by the drive motor 73a, the gear 73b is perpendicular to the rack portion 73c because the teeth of the gear 73b and the teeth of the rack portion 73c extending in the vertical direction mesh with each other. It moves relative to the direction. As a result, the moving member 73d to which the drive motor 73a is attached moves relative to the support member 72a to which the rack portion 73c is attached, so that the moving member 73d is attached to the moving member 73d. The winding needle 71a of the upper winding member 71 is moved in the stacking direction of the stacked coins (that is, the vertical direction in FIGS. 7 to 9) with respect to the support member 72a.

  The moving member 73d is provided with a fixed position detection sensor 79 such as a photo interrupter for detecting whether or not the upper winding needle 71a is located at a predetermined reference position.

In the fixed position detection sensor 79 having such a configuration, when the light emitted from the light emitting element is blocked by the detection plate 72g and is not received by the light receiving element, the upper winding needle 71a is positioned at a predetermined reference position. Is detected.

  Further, in the present embodiment, when the upper and lower end portions of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound and fixed to the upper and lower end portions of the accumulated coin by the respective winding needles 71a, the winding needle position adjustment is performed. The winding needle 71a of the upper winding member 71 may be moved by the portion 73 in the stacking direction of the accumulated coins (more specifically, the upward direction in the vertical direction) with respect to the support member 72a. In this case, the movement displacement amount of the upper winding needle 71a is determined by the movement displacement amount of the support member 72a by the winding needle driving unit 72 (that is, the downward movement displacement amount of the support member 72a) and the winding needle. This is the vector sum of the adjustment movement displacement amount of the upper winding needle 71a relative to the support member 72a by the position adjustment unit 73 (that is, the upward movement displacement amount of the upper winding needle 71a relative to the support member 72a). That is, when the adjustment movement displacement amount of the upper winding needle 71a relative to the support member 72a by the winding needle position adjustment unit 73 is larger than the movement displacement amount of the support member 72a by the winding needle drive unit 72, the accumulated coins In contrast, the upper winding needle 71a moves in the direction of separating. In addition, the adjustment movement displacement amount of the upper winding needle 71a relative to the support member 72a by the winding needle position adjustment unit 73 is substantially the same as the movement displacement amount of the support member 72a by the winding needle drive unit 72. The upper winding needle 71a does not move with respect to the accumulated coins. Further, when the adjustment movement displacement amount of the upper winding needle 71a relative to the support member 72a by the winding needle position adjustment unit 73 is smaller than the movement displacement amount of the support member 72a by the winding needle drive unit 72, the accumulated coins The upper winding needle 71a moves in a direction approaching.

  In the present embodiment, the coin packaging unit 90 according to the present invention is configured by combining the packaging unit 60 and the winding mechanism 70 described above.

  Next, it is pulled out from the mounting unit 80 to which a packaging medium roll wound with a packaging medium such as a wrapping paper or a packaging film to be sent to the packaging unit 60 is mounted, or from the packaging medium roll mounted to the mounting unit 80 A configuration of a mechanism or the like for sending the packaging medium to the packaging unit 60 will be described with reference to FIGS. 3 and 4. 3 and 4, the packaging medium roll is indicated by the reference symbol R, and the packaging medium drawn from the packaging medium roll is indicated by the reference symbol P.

  As described above, the mounting portion 80 is provided with the columnar support member 81 extending in the vertical direction, and the packaging medium roll is formed by passing the hollow portion of the core of the packaging medium roll through the support member 81. It is attached to the attachment portion 80. Further, the packaging medium drawn out from the packaging medium roll mounted on the mounting unit 80 is guided to the packaging region 61 of the packaging unit 60 by the packaging medium guide member 88 through between the pair of guide rollers 82 and 84.

A cutting member 86 made of, for example, a cutter or the like is provided, and the cutting medium 86 allows the packaging medium to be sent to the packaging region 61 of the packaging unit 60 to have a predetermined length. It is supposed to be disconnected. Further, as shown in FIGS. 2 to 4, in the vicinity of the packaging area 61 of the packaging unit 60, a packaging medium for guiding the packaging medium sent from the packaging medium guiding member 88 to the packaging area 61 of the packaging unit 60. A guide member 64 is provided.

  FIG. 10 is a functional block diagram showing the configuration of the control system of the coin wrapping machine 10 according to the present embodiment. The coin wrapping machine 10 according to the present embodiment has a control unit 200 that controls each component of the coin wrapping machine 10. Specifically, the control unit 200 includes a coin storage unit 29, a feeding unit 30, a transport unit 40, a drive motor 63, a cam shaft drive motor 75, a denomination switching cam shaft drive motor 78, a drive motor 82p, and a drive motor 73a. The fixed position detection sensor 79, the fixed position detection sensor 59i, the identification sensor 45, the counting sensor 46, the stopper 47, the operation display unit 100, the storage unit 202, and the like are connected to each other. And the control part 200 is used for the coin storage part 29, the feeding part 30, the conveyance part 40, the drive motor 63, the cam shaft drive motor 75, the denomination switching cam shaft drive motor 78, the drive motor 82p, the drive motor 73a, the stopper 47, etc. These components are controlled by sending command signals. Also, information related to detection results by the fixed position detection sensor 79, fixed position detection sensor 59i, identification sensor 45, counting sensor 46, and the like is sent to the control unit 200.

  As shown in FIG. 10, a denomination setting unit 210, a contact detection unit 212, and a winding needle movement amount setting unit 214 are connected to the control unit 200. The denomination setting unit 210 is configured to set the denomination of coins to be packaged by the packaging unit 60 based on information input from the operation display unit 100 by the operator. Further, when the contact detection means 212 winds and fixes the upper and lower end portions of the wrapping medium wound around the accumulated coins in the wrapping portion 60 to the upper and lower end portions of the accumulated coins by the respective winding needles 71 a, It detects that it contacted the end face of the accumulation coin. The winding needle movement amount setting unit 214 sets a second distance (described later) relating to the movement amount of the winding needle 71a in the stacking direction of the stacked coins. Details of the functions of the denomination setting unit 210, the contact detection means 212, and the winding needle movement amount setting unit 214 will be described later.

  In the present embodiment, the control unit 200, the storage unit 202, the denomination setting unit 210, the contact detection unit 212, and the winding needle movement amount setting unit 214 are included in the coin packaging unit 90. Also good.

  Next, the operation of the coin wrapping machine 10 having such a configuration, specifically, a coin wrapping method by the coin wrapping machine 10 will be described. In addition, operation | movement of the coin packaging machine 10 as shown below is performed because the control part 200 controls each structural member of the coin packaging machine 10. FIG.

  In the coin wrapping machine 10 according to the present embodiment, the denomination of the coin to be wrapped by the wrapping unit 60 is set in advance in the control unit 200. Can be changed by the operation display unit 100. At this time, the denomination setting unit 210 sets the denomination of the coin to be packaged by the packaging unit 60 based on the information input from the operation display unit 100 by the operator. When the denomination setting unit 210 sets the denomination of the coin to be wrapped by the packaging unit 60, the denomination switching cam shaft 77 is set by the denomination setting cam 210 by the denomination switching cam shaft drive motor 78. It can be rotated by the amount of rotation corresponding to the denomination. Thus, the positions of the packaging rollers 62b and 62c are automatically changed, and the distance between the fixed guide 36 and the movable guide 38 is automatically adjusted.

  In the present embodiment, based on the denomination set by the denomination setting unit 210, the position of the upper winding needle 71a is automatically adjusted by the winding needle position adjusting unit 73 along the stacking direction of the accumulated coins. Adjusted. Specifically, as described above, when the gear 73b is rotated by the drive motor 73a by the rotation amount corresponding to the denomination set by the denomination setting unit 210, the upper winding with respect to the support member 72a is performed. The needle 71a moves by an amount corresponding to the denomination set by the denomination setting unit 210. More specifically, in the present embodiment, this is detected by the fixed position detection sensor 79 when the upper winding needle 71a is located at a predetermined reference position. Then, the winding needle position adjusting unit 73 has a packaging unit in the stacking direction of the stacked coins from a predetermined reference position such that the upper winding needle 71a with respect to the support member 72a is detected by the fixed position detection sensor 79. 60 is moved to a position separated by a first distance corresponding to the denomination of the coin to be wrapped. In addition, such a 1st distance is set corresponding to each denomination of the coin which should be packaged by the packaging part 60, and respond | corresponds to the denomination of the coin which should be packaged by the packaging part 60, and the said denomination. The first distance is associated with and stored in the storage unit 202. Thus, when the position of the upper winding needle 71a is automatically adjusted along the stacking direction of the accumulated coins by the winding needle position adjusting unit 73, each winding needle 71a stacks the upper and lower ends of the packaging medium. It is possible to prevent the surface of the coin from being damaged, the cutting phenomenon of the packaging medium, or the insufficient winding of the packaging medium from occurring when the coin is completely wound on the upper and lower ends.

  Further, in the present embodiment, the second distance related to the moving amount of the winding needle 71a in the stacking direction of the stacked coins may be set by the winding needle moving amount setting unit 214. Here, the second distance is to correct individual variations (machine difference) of the coin wrapping machine 10. The operator can input the second distance relating to the individual variations of the coin wrapping machine 10 through the operation display unit 100, and the winding needle movement amount setting unit 214 can display the operation by the operator. Based on the information input by the unit 100, the second distance related to the amount of movement of the winding needle 71a in the stacking direction of the stacked coins is set. In this case, the winding needle position adjusting unit 73 is configured to stack the accumulated coins from a predetermined reference position such that the upper winding needle 71a with respect to the support member 72a is detected by the fixed position detection sensor 79. In FIG. 2, the first distance corresponding to the denomination of the coin to be packaged by the packaging unit 60 and the second distance set by the entrainment needle movement amount setting unit 214 are moved to a position separated by a total distance. According to such a technical matter, the position of the upper winding needle 71 a can be adjusted more finely by the winding needle position adjusting unit 73.

  After the position of the upper winding needle 71a is adjusted along the stacking direction of the stacked coins by the winding needle position adjusting unit 73, the operator inserts coins into the coin receiving area of the coin receiving unit 22 of the coin inserting mechanism 20. When the coin receiver 22 is moved to the coin feed position by grasping and lifting a handle (not shown) provided at the right end of the coin receiver 22, the coin receiver 22 is accumulated on the bottom surface of the coin receiver 22. The coins that are present are sent from the coin receiving portion 22 to the inside of the housing 12 by its own weight. Coins sent from the coin receiving part 22 to the inside of the housing 12 are stored in the coin storage part 29, and sent from the coin storage part 29 to the feeding part 30 by several to several tens. Coins received on the rotating disk 32 of the feeding unit 30 are fed one by one to the transport path 42 of the transport unit 40 by the feeding unit 30. Then, in the stacking unit 50, the coins sent to the stacking region 51 of the stacking unit 50 from the transport path 42 of the transporting unit 40 are already stacked in the stacking region 51 so as to be stacked. The coins are sequentially accumulated from the lower side to the upper side by dragging them into the lower side of the coins. When coins corresponding to the number of packaging units are accumulated in the accumulating unit 50, the accumulated coins are raised to a predetermined packaging position in the packaging unit 60 by the accumulated coin transport unit 59. Moreover, when the coins for the number of packaging units are stacked in the stacking unit 50, the transport of coins by the transport unit 40 is temporarily stopped.

  Here, in the coin wrapping machine 10 according to the present embodiment, the number of coins sent from the transport path 42 of the transport unit 40 to the stacking unit 50 is counted by the count sensor 46, and the number of coins counted by the count sensor 46 is calculated. Every time the predetermined number is reached, several to several tens of coins are sent from the coin storage unit 29 to the feeding unit 30. According to such a method, it is not necessary to install a residual detection sensor such as a photo interrupter for detecting coins remaining in the feeding unit 30 in the feeding unit 30, and the manufacturing cost of the coin packaging machine 10 is reduced. Will be able to.

  When the accumulated coins are conveyed from the accumulation unit 50 to the packaging unit 60, the accumulated coins are collected in the packaging unit 60 by sending the packaging medium drawn from the packaging medium roll attached to the attachment unit 80 to the packaging region 61 of the packaging unit 60. Wrap the wrapping media around. Specifically, in the packaging unit 60, the cam shaft 74 rotates once every time one wrapping coin is produced, and is accumulated by the three packaging rollers 62a, 62b, and 62c during one rotation of the cam shaft 74. While the coins are sandwiched and rotated, the packaging medium drawn out of the packaging medium roll and cut into a predetermined length by the cutting member 86 is collected by the packaging medium guide member 64 with the three packaging rollers 62a, 62b, 62c and the accumulated coins. Supply between. When the packaging medium is supplied to the packaging region 61 of the packaging unit 60, the winding needle 71 a of the winding mechanism 70 is located at a retracted position so as to retract from the packaging region 61 of the packaging unit 60.

  After that, as shown in FIG. 4, the winding needle 71 a of the winding mechanism 70 is moved to an advance position that advances into the packaging region 61 of the packaging unit 60. After the winding needle 71a of the winding mechanism 70 moves to the advanced position where it advances into the packaging area 61 of the packaging unit 60, the upper and lower ends of the packaging medium wound around the circumferential surface of the accumulated coins are wound up by the winding mechanism 70. The pair of upper and lower winding needles 71a are wound around the upper and lower end faces of the accumulated coin and fixed. When the winding operation of both the upper and lower end surfaces of such an accumulated coin is completed, the pair of upper and lower winding needles 71a are retracted to the initial position, and then the three packaging rollers 62a, 62b, 62c are opened to wrap the coins. Is discharged downward and stored in a wrapping coin storage box provided below the stacking unit 50.

  When the three wrapping rollers 62a, 62b, 62c are opened to release the wrapping coins downward and are stored in the wrapping coin storage box provided below the stacking unit 50, the coin pressing member 59c is at the lowest position. The coin holding member 59c is detected by the fixed position detection sensor 59i. When the coin holding member 59c is detected by the fixed position detection sensor 59i, after a predetermined time has elapsed, a shutter (not shown) for throwing the wrapping coins downward is closed and the coins by the transport unit 40 are removed. The conveyance is resumed.

  Here, conventionally, when three wrapping rollers 62a, 62b, and 62c are opened to release the wrapping coins downward and are stored in a wrapping coin storage box provided below the stacking unit 50, After a predetermined time elapses after the wrapping rollers 62a, 62b, and 62c are opened, a shutter (not shown) for throwing the wrapping coins downward is closed and the transporting unit 40 transports the coins. It was supposed to be resumed. However, in such a method, it is impossible to track the movement of the wrapping coins that are thrown downward, so that the time between the opening of the three wrapping rollers 62a, 62b, and 62c and the closing of the shutter is as follows. There is a problem that it is necessary to have a margin and this time becomes long. On the other hand, in this embodiment, since the fixed position detection sensor 59i that detects the coin pressing member 59c is provided when the coin pressing member 59c is positioned at the lowest position, the packaging to be thrown out downward is provided. The movement of the coin can be tracked. Therefore, after a predetermined time has elapsed after the coin pressing member 59c is detected by the fixed position detection sensor 59i, a shutter for throwing out the wrapping coin downward. Close (not shown). As a result, the time until the shutter is closed can be shortened, so that the timing at which the coin for creating the next wrapping coin is transported by the transport unit 40 can be advanced.

Further, in the present embodiment, when the upper and lower ends of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound and fixed to the upper and lower end portions of the accumulated coin by the respective winding needles 71a, at a predetermined timing, The upper winding needle 71 a may be automatically adjusted by the winding needle position adjusting unit 73 in the direction opposite to the direction in which each winding needle 71 a is moved by the winding needle driving unit 72. . That is, when the upper and lower ends of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound and fixed on the upper and lower ends of the accumulated coin by the respective winding needles 71a, the winding needle position adjusting unit is at a predetermined timing. 73, the winding needle 71a of the upper winding member 71 may be moved in the stacking direction of the accumulated coins (more specifically, upward in the vertical direction) with respect to the support member 72a. Here, the predetermined timing is a timing before the timing at which each winding needle 71a becomes the amount of movement displacement to be brought into contact with the end face of the accumulated coin. At a predetermined timing, the amount of movement displacement of the upper winding needle 71a is the amount of movement displacement of the support member 72a by the winding needle driving unit 72 (that is, the amount of downward movement displacement of the support member 72a), The vector sum of the adjustment movement displacement amount of the upper winding needle 71a relative to the support member 72a by the winding needle position adjustment unit 73 (that is, the adjustment movement displacement amount of the upper winding needle 71a relative to the support member 72a) Become. According to such a technical matter, when the upper and lower ends of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound around and fixed to the upper and lower ends of the accumulated coin, the upper winding needle 71a is fixed. It becomes possible to prevent contact with the upper end surface of the accumulated coins. Such technical matters will be described with reference to FIGS. Note that in FIG. 11 through FIG. 13, shows where the upper end of the packaging medium wound stacked coins is fixed by caught in the upper end surface of the stacked coins by the upper winding needle 71a by the reference numeral P _1.

FIG. 11 is a side view showing a state when the upper winding needle 71a contacts the upper end surface of the accumulated coin in the winding mechanism 70 shown in FIG. When the upper winding needle 71a comes into contact with the upper end surface of the accumulated coins, as shown in FIG. 13, when the accumulated coins are rotated by the packaging rollers 62a, 62b, 62c of the packaging unit 60, rotation of the top layer of coins (indicated by reference character C ₁ in FIG. 13) is stopped by the upper winding needle 71a, Thus, the second and subsequent coin from the top and uppermost coin in the stack of coins In some cases, the wrapping medium may be cut (a so-called cut-off phenomenon occurs). In order to prevent such a phenomenon from occurring, at a timing (that is, the above-described predetermined timing) before the timing at which each of the winding needles 71a becomes the amount of movement displacement to be brought into contact with the end face of the accumulated coin, As indicated by an arrow in FIG. 12, the upper winding needle 71a is moved by the winding needle position adjusting unit 73 in a direction away from the upper end surface of the accumulated coins. In this case, the upper winding needle 71a is moved by the winding needle driving unit 72 in a direction approaching the upper end surface of the accumulated coins (that is, the downward direction in FIG. 12). 73, by moving the upper winding needle 71a away from the upper end surface of the accumulated coin, the movement displacement amount of the upper winding needle 71a is the movement displacement amount of the support member 72a by the winding needle drive unit 72. (That is, the downward movement displacement amount of the support member 72a) and the adjustment movement displacement amount of the upper winding needle 71a relative to the support member 72a by the winding needle position adjustment unit 73 (that is, the upper winding amount relative to the support member 72a) The upper and lower end portions of the wrapping medium wound around the stacked coins at the upper and lower ends of the accumulated coins by the respective winding needles 71a. Upper winding needle 71a even when the finished winding each end will not contact the upper end surface of the stacked coins. As a result, it is possible to prevent the packaging medium from being cut between the uppermost coin and the second and subsequent coins in the accumulated coin.

  Next, the timing at which the upper winding needle 71a is automatically adjusted by the winding needle position adjusting unit 73 (that is, the predetermined timing described above) will be described in more detail. In the coin wrapping machine 10 of the present embodiment, when the upper and lower ends of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound and fixed to the upper and lower end portions of the accumulated coin by the respective winding needles 71a, the winding is wound. Contact detecting means 212 for detecting that the needle 71a is in contact with the end face of the accumulated coin is provided. The storage unit 202 also includes a denomination of coins to be packaged by the packaging unit 60, timings at which the respective winding needles 71a come into contact with the end surfaces of the accumulated coins detected by the contact detection means 212, and driving of the winding needles. The movement displacement amount of each winding needle 71a by the unit 72 and the adjustment movement displacement amount of the upper winding needle 71a by the winding needle position adjustment unit 73 are stored in association with each other. Then, the predetermined timing is that each winding needle 71a detected by the contact detection means 212, which is stored in the storage unit 202, corresponding to the denomination of the coin to be packed by the packing unit 60 is placed on the end face of the accumulated coins. It is determined based on the contact timing, the movement displacement amount of each winding needle 71a by the winding needle driving unit 72, and the adjustment movement displacement amount of the upper winding needle 71a by the winding needle position adjusting unit 73.

  More specifically, the contact detection means 212 detects information related to the timing at which each winding needle 71a contacts the end face of the accumulated coins for all denominations of the coins to be packed by the packaging unit 60 by a prior test. The information is acquired in advance based on the result, and the acquired information is stored in the storage unit 202. In addition, the rotation angle of the cam shaft driving motor 75 that drives the winding needle drive unit 72 configured by, for example, a stepping motor or the like is used as information related to the timing at which each winding needle 71a contacts the end face of the accumulated coin. It has become. In addition, information relating to the movement displacement amount of each winding needle 71a by the winding needle drive unit 72 and the adjustment movement displacement amount of the upper winding needle 71a by the winding needle position adjustment unit 73 is acquired in advance by a test. The acquired information is stored in the storage unit 202. For each denomination, the timing (specifically, for example, the rotation angle of the camshaft drive motor 75) at which the upper winding needle 71a reaches a position spaced apart from the upper end surface of the accumulated coin by a predetermined distance, The timing at which each winding needle 71a detected by the contact detection means 212 contacts the end face of the accumulated coin, the amount of movement displacement of each winding needle 71a by the winding needle driving unit 72, and the winding needle stored in the storage unit 202 This is calculated based on the amount of adjustment movement displacement of the upper winding needle 71a by the position adjustment unit 73. The timing calculated in this way is the predetermined timing.

  The contact detection means 212 has a moving amount of the winding needle 71a when the upper and lower ends of the wrapping medium wound around the accumulated coin in the packaging unit 60 are respectively wound and fixed on the upper and lower ends of the accumulated coin by the respective winding needles 71a. When the change does not occur, it is detected that the winding needle 71a contacts the end face of the accumulated coin. More specifically, the contact detection means 212 includes an optical sensor or a switch such as a photo interrupter that detects that the winding needle 71a has come into contact with the end face of the accumulated coin. It is detected that the needle 71a has come into contact with the end face of the accumulated coin. The contact detection unit 212 is not limited to an optical sensor or a switch. For example, when a current is passed between the pair of upper and lower winding needles 71a and each winding needle 71a comes into contact with the end face of the accumulated coins, the current flows between these winding needles 71a and the accumulated coins. The contact detecting means 212 may detect that the needle 71a is in contact with the end face of the accumulated coin.

  Further, as the contact detection means 212, a detection sensor 74g such as a photo interrupter that detects whether or not the upper arm 72b is in contact with the pushing roller 74e provided at the tip of the upper lever 74b may be used. . The configuration of such a detection sensor 74g will be described with reference to FIGS.

  As shown in FIGS. 14 and 15, the upper lever 74b is provided with a detection sensor 74g such as a photo interrupter for detecting the detection plate 72f attached to the upper arm 72b. Here, as shown in FIG. 14, when the upper arm 72b is in contact with the pushing roller 74e provided at the tip of the upper lever 74b, that is, the upper winding needle 71a is When separated from the end face, the optical axis between the light emitting element and the light receiving element in the detection sensor 74g is blocked by the detected plate 72f. On the other hand, as shown in FIG. 15, when the upper arm 72b is separated from the pushing roller 74e provided at the tip of the upper lever 74b, that is, the upper winding needle 71a is the upper end surface of the accumulated coins. Since the detection sensor 74g attached to the upper lever 74b is also spaced downward from the upper arm 72b, the contact between the light-emitting element and the light-receiving element in the detection sensor 74g. The optical axis is not blocked by the detected plate 72f, so that the light emitted from the light emitting element can be received by the light receiving element. In this way, whether or not the upper arm 72b is in contact with the pushing roller 74e provided at the tip of the upper lever 74b, that is, whether or not the upper winding needle 71a is in contact with the upper end surface of the accumulated coins. Whether or not can be detected by the detection sensor 74g.

  Here, when the upper winding needle 71a is spaced upward from the upper end surface of the accumulated coins, a pair of upper and lower arms is provided by a spring (not shown) provided on each of the upper and lower pairs of arms 72b. Since 72b is urged in a direction approaching each other, the upper arm 72b is urged downward in FIG. 14 to come into contact with a pushing roller 74e provided at the tip of the upper lever 74b. . In this case, the detection sensor 74g is in a light shielding state. On the other hand, when the upper winding needle 71a is in contact with the upper end surface of the accumulated coin, the upper arm 72b is attached downward by a spring (not shown) provided on each of the pair of upper and lower arms 72b. Even if the upper arm 72b is pressed, the upper arm 72b does not move further downward from the state shown in FIG. 15 because the upper winding needle 71a is in contact with the upper end surface of the accumulated coins. This prevents contact with the pressing roller 74e provided at the tip of the lever 74b. In this case, the detection sensor 74g is in a translucent state. Thus, when the detection sensor 74g is used as the contact detection means 212, the upper winding needle 71a is in contact with the upper end surface of the accumulated coins depending on whether or not the detection sensor 74g is in a light shielding state. It becomes possible to determine whether or not.

  Further, in the present embodiment, when the upper and lower end portions of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound and fixed to the upper and lower end portions of the accumulated coin by the respective winding needles 71a, the upper winding needles If the contact detection means 212 does not detect that 71a has contacted the end face of the accumulated coins at the second predetermined timing, whether the accumulated coins to be packaged by the packaging unit 60 have not reached the predetermined number or the packaging unit The control unit 200 may determine that the length in the stacking direction of the stacked coins to be packaged by 60 is smaller than a predetermined length. Here, the second predetermined timing is that each winding needle 71a should contact the end face of the accumulated coins when the length of the accumulated coins in the accumulation direction is a predetermined length, which is stored in the storage unit 202. The timing is the same as or later than the timing of the displacement amount. In addition, the second predetermined timing is the information stored in the storage unit 202 (specifically, each winding needle 71a associated with the denomination of the coin to be wrapped by the packaging unit 60 is the accumulated coin). The timing of contact with the end face, the amount of movement displacement of each winding needle 71a by the winding needle drive unit 72, and the amount of adjustment movement displacement of the upper winding needle 71a by the winding needle position adjustment unit 73). ing.

More specifically, for example, the rotation angle of the camshaft drive motor 75 as a parameter for managing timing is θ, and a predetermined number (N) of wrapping coins are created, and the upper winding needle 71a is created. N data is collected at the timing of contact with the upper end surface of the accumulated coins (rotation angle θ of the camshaft drive motor 75). The timing at which the upper winding needle 71a contacts the upper end surface of the accumulated coin is affected by the amount of adjustment movement displacement of the upper winding needle 71a by the winding needle position adjusting unit 73. For example, the adjustment movement displacement amount = 0. Then, θ, which is the collected timing data (rotation angle) for N, is statistically processed, and an average value M and a standard deviation σ are calculated. Thereafter, the second predetermined timing θ2 is calculated by the following equation (1).
θ2 = M + (X × σ) + α (1)
However, X is a numerical value related to the reliability of how many times the standard deviation is 1, 2, 3, etc., and α is a constant. Then, θ2 calculated by the above formula (1) may be set as the second predetermined timing when the adjustment movement displacement amount of the upper winding needle 71a by the winding needle position adjusting unit 73 = 0. Data of θ2 in which the adjustment movement displacement amount is changed in the same manner is collected and stored in the storage unit 202, and the movement displacement amount of each winding needle 71 a by the winding needle driving unit 72 and the winding needle position adjusting unit 73. The actual second predetermined timing may be determined in a timely manner based on the amount of adjustment movement displacement of the upper winding needle 71a.

  When the number of accumulated coins to be packaged by the packaging unit 60 has not reached the predetermined number or the length of the accumulated coins to be packaged by the packaging unit 60 is smaller than the predetermined length, the contact detection means The timing at which each winding needle 71a comes into contact with the end face of the accumulated coin, detected by 212, is such that each winding needle 71a comes into contact with the end face of the accumulated coin when the length of the accumulated coin in the accumulation direction is a predetermined length. It will be later than the right timing. Therefore, when the length of the stacked coins in the stacking direction is a predetermined length, the second predetermined timing is the same timing as or later than the timing at which each winding needle 71a should contact the end face of the stacked coins. When the contact detection means 212 does not detect that the upper winding needle 71a has contacted the end face of the accumulated coin at the timing, the distance between the pair of winding needles 71a at the second predetermined timing is the packaging portion. 60, it is considered that the accumulated coins to be packaged by the packaging unit 60 have not reached a predetermined number or are packed by the packaging unit 60. The control unit 200 determines that the length in the accumulation direction of the power accumulation coins is smaller than a predetermined length.

  Further, in the present embodiment, when the upper and lower end portions of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound and fixed to the upper and lower end portions of the accumulated coin by the respective winding needles 71a, the upper winding needles are fixed. If it is detected by the contact detection means 212 at the third predetermined timing that the 71a has come into contact with the end face of the accumulated coins, whether the accumulated coins to be packed by the packaging unit 60 are larger than the predetermined number or the packaging unit The control unit 200 determines that the length in the stacking direction of the stacked coins to be packed in 60 is larger than a predetermined length. Here, the third predetermined timing is a timing that is stored in the storage unit 202 and that is before the timing at which each of the winding needles 71a becomes the amount of movement displacement that should contact the end face of the accumulated coin. In addition, the third predetermined timing is the information stored in the storage unit 202 (specifically, each winding needle 71a associated with the denomination of the coin to be packaged by the packaging unit 60 is the accumulated coin). The timing of contact with the end face, the amount of movement displacement of each winding needle 71a by the winding needle drive unit 72, and the amount of adjustment movement displacement of the upper winding needle 71a by the winding needle position adjustment unit 73). ing.

More specifically, the average value M and the standard deviation σ of the rotation angle of the camshaft drive motor 75 are calculated in the same manner as the second predetermined timing. Thereafter, a third predetermined timing θ3 is calculated by the following equation (2).
θ3 = M− (X × σ) −β Expression (2)
However, X is a numerical value related to the reliability of how many times the standard deviation is 1, 2, 3, etc., and β is a constant. Then, θ3 calculated by the above equation (2) may be the third predetermined timing when the adjustment movement displacement amount of the upper winding needle 71a by the winding needle position adjusting unit 73 = 0. Data of θ3 in which the adjustment movement displacement amount is changed in the same manner is collected and stored in the storage unit 202, and the movement displacement amount of each winding needle 71a by the winding needle driving unit 72 and the winding needle position adjusting unit 73. The actual third predetermined timing may be determined in a timely manner based on the adjustment movement displacement amount of the upper winding needle 71a.

  When the number of accumulated coins to be packaged by the packaging unit 60 is larger than a predetermined number, or when the length of the accumulated coins to be packaged by the packaging unit 60 is larger than the predetermined length, the contact detection unit 212. The timing at which each winding needle 71a comes into contact with the end surface of the accumulated coin, detected by the above, should be in contact with the end surface of the accumulated coin when the length in the stacking direction of the accumulated coin is a predetermined length. It will be earlier than the timing. For this reason, when the length of the stacked coins in the stacking direction is a predetermined length, at the third predetermined timing, which is a timing before each winding needle 71a should contact the end surface of the stacked coins, When the contact detecting means 212 detects that the winding needle 71a is in contact with the end face of the accumulated coins, the number of accumulated coins to be wrapped by the packaging unit 60 is greater than a predetermined number or the packaging unit 60 The control unit 200 determines that the length in the stacking direction of the stacked coins to be packaged is greater than a predetermined length.

  In the above description, the position of the upper winding needle 71a of the pair of upper and lower winding needles 71a is automatically adjusted by the winding needle position adjusting unit 73 along the stacking direction of the accumulated coins. Yes. Here, in the present embodiment, when the packaging medium drawn out from the packaging medium roll attached to the attachment unit 80 is sent to the packaging unit 60, the lower end position thereof is substantially the same regardless of the size of the packaging medium. ing. For this reason, it is not necessary to adjust the position of the lower winding needle 71a even if the size of the packaging medium is changed by changing the denomination of the coin to be packaged by the packaging unit 60. However, in the coin wrapping unit 90 of the present embodiment, the position of the upper winding needle 71a of the pair of upper and lower winding needles 71a is automatically adjusted by the winding needle position adjusting unit 73 along the stacking direction of the accumulated coins. It is not limited to such an embodiment. As the coin packaging unit 90 of the present embodiment, the position of the upper winding needle 71a and the position of the lower winding needle 71a are automatically adjusted by the winding needle position adjusting unit 73 along the stacking direction of the stacked coins. Such a mode may be used. As still another example, only the position of the lower winding needle 71a of the pair of upper and lower winding needles 71a is automatically adjusted by the winding needle position adjusting unit 73 along the stacking direction of the stacked coins. The thing of an aspect may be used.

  According to the coin wrapping unit 90 of the present embodiment configured as described above and the coin wrapping machine 10 provided with such a coin wrapping unit 90, the winding mechanism 70 includes a pair of upper and lower winding needles 71a, The winding needle drive unit 72 that can move the pair of upper and lower winding needles 71a toward and away from each other and the position of at least one of the pair of upper and lower winding needles 71a are integrated. And a winding needle position adjusting unit 73 that automatically adjusts along the coin accumulation direction. In this case, by automatically adjusting the position of at least one of the upper and lower winding needles 71a along the stacking direction of the stacked coins by the winding needle position adjusting unit 73, the winding needle is adjusted. When 71a finishes winding the upper and lower ends of the packaging medium around the upper and lower ends of the accumulated coin, the surface of the coin may be damaged, the packaging medium may be cut, or the packaging medium may be insufficiently wound. Can be suppressed.

  More specifically, conventionally, when changing the denomination of a coin to be packed by a packing unit in a coin wrapping machine, the roll of the packaging medium is changed and the upper winding of the pair of upper and lower winding needles is changed. The position of the needle was manually adjusted by the operator. However, in this case, there is a problem that it takes time and effort to change the denomination of the coin to be packaged. In addition, when changing the denomination of the coin to be packaged, the operator may forget to adjust the position of the upper winding needle among the pair of upper and lower winding needles even if the roll of the packaging medium is replaced. there were. In such a case, when the winding needle finishes winding the upper and lower end portions of the packaging medium to the upper and lower end portions of the accumulated coin, the surface of the coin is damaged by the contact of the winding needle with the surface of the coin. Or a wrapping medium cutting phenomenon (so-called end cutting) due to the stoppage of coin rotation, or insufficient wrapping of the wrapping medium due to insufficient stroke of the winding needle. On the other hand, in the coin wrapping unit 90 of the present embodiment, the position of at least one of the upper and lower winding needles 71a is set by the winding needle position adjusting unit 73 along the stacking direction of the accumulated coins. By adjusting automatically, such problems of the prior art can be solved.

  Moreover, in the coin wrapping unit 90 of the present embodiment, as described above, the denomination setting unit 210 that sets the denomination of the coin to be wrapped by the wrapping unit 60 is provided, and the winding needle position adjustment is performed. Based on the denomination set by the denomination setting unit 210, the unit 73 automatically adjusts the position of at least one of the upper and lower winding needles 71a along the stacking direction of the stacked coins. It is like that.

  Further, in the coin wrapping unit 90 of the present embodiment, as described above, the upper and lower ends of the wrapping medium wound around the accumulated coins in the wrapping unit 60 are moved up and down by the respective winding needles 71a of the winding mechanism 70. When each of the winding needles 71a is moved by the winding needle driving unit 72 at a predetermined timing when it is wound and fixed at both ends, the movement displacement of at least one of the winding needles 71a. Is automatically adjusted by the winding needle position adjusting unit 73. Here, the predetermined timing is a timing before the timing at which each winding needle 71a becomes the amount of movement displacement to be brought into contact with the end face of the accumulated coin. In addition, when the upper and lower end portions of the wrapping medium wound around the accumulated coins in the wrapping portion 60 are respectively wound around the upper and lower end portions of the accumulated coins by the respective winding needles 71a in the coin wrapping unit 90 of the present embodiment. Contact detecting means 212 is provided for detecting that the winding needle 71a contacts the end face of the accumulated coin. In addition, the denomination of the coin to be packaged by the packaging unit 60, the timing at which each winding needle 71a is in contact with the end face of the accumulated coin, detected by the contact detection means 212, and the winding needle by the winding needle driving unit 72 The movement displacement amount of 71a and the adjustment movement displacement amount of the winding needle 71a by the winding needle position adjusting unit 73 are stored in association with the storage unit 202, and the predetermined timing is determined by the packaging unit 60. Corresponding to the denomination of the coin to be wrapped, the timing at which each of the winding needles 71a detected by the contact detection means 212, which is stored in the storage unit 202, comes into contact with the end face of the accumulated coins, by the winding needle driving unit 72 The movement displacement amount of the winding needle 71a and the adjustment movement displacement amount of the winding needle 71a by the winding needle position adjusting unit 73 are determined.

  Here, the contact detection means 212 is configured so that the upper and lower end portions of the wrapping medium wound around the accumulated coin in the wrapping portion 60 are respectively wound on and fixed to the upper and lower end portions of the accumulated coin by the respective winding needles 71a. When the amount of movement does not change, it is detected that the winding needle 71a has come into contact with the end face of the accumulated coin. More specifically, the contact detection means 212 may include an optical sensor or a switch that detects that the winding needle 71a has contacted the end face of the accumulated coin. Further, the contact detecting means 212 is configured such that when the winding needle 71a comes into contact with the end face of the accumulated coin and a current flows between the winding needle 71a and the accumulated coin, the winding needle 71a is brought into contact with the end face of the accumulated coin. You may come to detect having contacted.

  Moreover, in the coin wrapping unit 90 of the present embodiment, as described above, the upper and lower ends of the wrapping medium wound around the accumulated coins in the wrapping portion 60 are respectively wound on the upper and lower ends of the accumulated coins by the respective winding needles 71a. When the contact detection means 212 does not detect that the winding needle 71a has contacted the end face of the accumulated coins at the second predetermined timing, the accumulated coins to be packaged by the packaging unit 60 are predetermined. It is determined that the number has not reached the number or the length in the stacking direction of the stacked coins to be packed by the packing unit 60 is smaller than a predetermined length. In this case, the second predetermined timing is a timing at which each of the winding needles 71a becomes a movement displacement amount to be brought into contact with the end face of the accumulated coin or a timing after that. Further, the second predetermined timing is determined based on information stored in the storage unit 202. According to such technical matters, the accumulated coins to be packaged by the packaging unit 60 have not reached a predetermined number, or the length of the accumulated coins to be packaged by the packaging unit 60 is a predetermined length. It is possible to automatically determine that the size is smaller than the above.

  Moreover, in the coin wrapping unit 90 of the present embodiment, as described above, the upper and lower ends of the wrapping medium wound around the accumulated coins in the wrapping portion 60 are respectively wound on the upper and lower ends of the accumulated coins by the respective winding needles 71a. When the contact detecting means 212 detects that the winding needle 71a contacts the end face of the accumulated coins at the third predetermined timing, the accumulated coins to be packaged by the packaging unit 60 are predetermined. Or the length of the accumulated coins to be packaged by the packaging unit 60 is determined to be larger than a predetermined length. In this case, the third predetermined timing is a timing before the timing at which each winding needle 71a becomes the amount of movement displacement to be brought into contact with the end face of the accumulated coin. Further, the third predetermined timing is determined based on information stored in the storage unit 202. According to such technical matters, the number of accumulated coins to be packaged by the packaging unit 60 is greater than the predetermined number, or the length of the accumulated coins to be packaged by the packaging unit 60 is longer than the predetermined length. Can be automatically determined to be large.

  The coin wrapping machine 10 according to the present embodiment and the coin wrapping unit 90 provided in such a coin wrapping machine 10 are not limited to the above-described aspects, and various changes can be made.

  For example, if at least the packaging unit 60 and the winding mechanism 70 are provided as the coin packaging unit 90 according to the present embodiment, installation of the coin insertion mechanism 20, the feeding unit 30, the transport unit 40, the mounting unit 80, and the like is omitted. You may come to be.

  Further, the winding needle position adjusting unit 73 is not limited to the one shown in FIGS. 7 to 9.
