Description

  The present invention relates to a coin stacking apparatus that stacks coins.

  In a coin wrapping machine that forms wrapping coins, coins are stacked by a coin stacking device, and stacked coins stacked by a predetermined number of times are packed by this coin stacking device.

  In the conventional coin stacking device, coins that have been transported horizontally one by one by the transport unit are received and stacked in the stacking unit. This stacking section has a stacking support section that moves in the vertical direction, and the stacking space that is formed above the stacking support section or the coin that is supported by this stacking support section. And stacked on the stacking support. Furthermore, the stacking support unit descends by a preset lowering amount in synchronization with the coin feeding from the transport unit so that the upper surface of the uppermost coin on the stacking support unit is always at the same height. In other words, the stacking space is always a certain size.

In addition, when a lot of thick coins are stacked in the stacking part or when the stacking part is clogged and the stacking space becomes narrow, the transporting part of the transporting part arranged above the stacking part Is pushed upward, and an abnormal stacking in the stacking portion is detected by detecting the pushing up of the conveying parts. When a stacking abnormality is detected, the stacking support part is lowered more than usual, and the upper space (stacking space) of coins is increased to eliminate the stacking abnormality (for example, Patent Documents). 1).

The transport unit 20 and the stacking unit 21 constitute a coin stacking device 23 that stacks coins.

  The wrapping section 22 includes three wrapping rollers 25. The stacked coins 16 stacked in the stacking section 21 are arranged between the wrapping rollers 25, sandwiched and rotated, and the wrapping paper 16 having a predetermined length is stacked. Wrapping around the circumferential surface of the stacked coins, the upper and lower ends of the wrapping paper 16 are wound around the upper and lower end surfaces of the stacked coins with a pair of upper and lower winding needles 26, and wrapping coins are created. The created wrapping coin is discharged downward and thrown out to the wrapping coin dispensing unit 15.

  In order to feed the wrapping paper 16 having a predetermined length, a paper feed roller 27 for feeding the wrapping paper 16 and a cutter 28 for cutting the wrapping paper 16 into a predetermined length are provided.

  Next, as illustrated in FIGS. 1 to 3, the transport unit 20 includes a transport path 31 that transports coins (indicated by reference numeral C in FIG. 1) in a single row state. The conveyance path 31 is formed on the passage bottom plate 32 between passage side plates 33 and 34 disposed on both sides of the passage bottom plate 32 so as to be movable in the passage width direction. The upper portion of the stacked portion 21 is disposed at the end of the transport path 31 on the downstream side in the transport direction. The positions of the passage side plates 33 and 34 are adjusted so as to change the passage width according to the setting of denominations to be packaged.

  Above the transport path 31, a transport belt 35 that transports coins in the transport path 31 toward the stacking portion 21 on the downstream side in the transport direction is disposed. Although only the conveyance belt 35 on the downstream side in the conveyance direction of the conveyance path 31 is shown in the figure, a conveyance belt (not shown) is also disposed on the upstream side in the conveyance direction. The conveyor belt 35 is an endless belt having a flat outer peripheral surface and is wound around a plurality of pulleys (only the pulley 36 on the downstream side in the conveyance direction) rotatably supported above the passage bottom plate 32. Has been.

  The pulley 36 on the downstream side in the transport direction is disposed above the stacking portion 21. The pulley 36 is rotatably supported by a shaft 37. The shaft 37 is attached to an end portion of a support plate 38. The support plate 38 is supported by a support shaft 39 so as to be swingable. Not attached to the frame side. Accordingly, the pulley 36 is supported so as to be swingable in the vertical direction with the support shaft 39 as a fulcrum.

  Although not shown in the transport path 31, an identification unit for identifying coins to be transported, a stopper for stopping coins following a predetermined number of packaging unit coins stacked in the stacking unit 21, and a packaging denomination There are provided a discharge port for removing coins having a smaller diameter, a count sensor for counting the number of coins sent from the transport unit 20 to the stacking unit 21, and the like.

  Next, the stacking unit 21 has a space 41 for receiving coins transported by the transporting unit 20 from above and stacking a predetermined number of packaging units. In this space portion 41, a pair of stacked belts 42 are respectively arranged on both sides of the space portion 41 corresponding to the direction orthogonal to the direction in which coins are conveyed from the conveying portion 20, and the coins are conveyed from the conveying portion 20. A first guide 43 and a second guide 44 are respectively arranged on both sides of the space 41 corresponding to the direction. The first guide 43 is disposed on the transport unit 20 side, and the second guide 44 is disposed on the opposite side of the transport unit 20. Therefore, a coin stacking space 41 is formed between the pair of stacked belts 42 and the first guide 43 and the second guide 44.

  The pair of stacked belts 42 are respectively stretched between the upper and lower pulleys 46, and are opposed to each other with a gap slightly wider than the diameter of coins to be wrapped on the belt surface. Stack support portions 47 are respectively attached to the surfaces of the pair of stack belts 42. On the upper surface of the stacking support portion 47, a stacking support surface 48 for supporting coins is formed. The stacking support surface 48 is formed on an inclined surface in which the first guide 43 side descends and the second guide 44 side rises so as to incline downward at a predetermined inclination angle toward the transport unit 20 side. . Then, on the stacking support portion 47 of the pair of stacking belts 42, the lowest coins stacked in the space 41 are placed in a state where the first guide 43 side is under the coin inclination, The coins are stacked in an inclined state so that the second guide 44 side is above the inclination of the coins.

  The pair of stacked belts 42 are rotated in conjunction with each other so that opposing surfaces of the pair of stacked belts 42 are directed in the same direction by driving of a stacking motor (see FIG. 5). Then, an accumulation space 49 having an appropriate size is formed between the stacking support portion 47 and the coins supported by the stacking support portion 47 and the conveyor belt 35. The coins sent out from the transport unit 20 are accepted and can be stacked. Each time the coins fed from the transport unit 20 are received and stacked one by one in the stacking space 49, the stacking support unit 47 of the pair of stacking belts 42 is lowered by driving the stacking motor. By descending by an amount, a stacking space 49 of an appropriate size is always formed so that coins can be stacked.

  The first guide 43 is formed of a plate that is long in the vertical direction along the space 41. At the upper end of the first guide 43, a guide roller 51 for guiding coins fed from the transport unit 20 to the upper portion of the space 41 is rotatably disposed.

  Further, the second guide 44 is formed to be long in the vertical direction along the space portion 41. A stopper body 53 is disposed above the second guide 44. The upper portion of the stopper body 53 is disposed above the space portion 41, and the lower portion of the stopper body 53 is disposed in the space portion 41.

  Above the stopper body 53, a stopper 54 that opposes the end of the transport section 20 above the space section 41 of the stacking section 21 and prevents the coins transported by the transport section 20 from popping out and dropping into the space section 41. Is formed. The stopper 54 is inclined so that the upper side approaches the center side of the space 41 and the lower side is separated from the space 41 in the outer diameter direction.

  The pair of stacked belts 42, the first guide 43, the second guide 44, the stopper body 53, and the like can be adjusted to move to positions corresponding to the denominations to be packaged by an adjusting mechanism (not shown). It is supported. With this adjustment mechanism, the opposing distance between the pair of stacked belts 42 is adjusted around the central axis of the space portion 41, and the stacked belts in a direction orthogonal to the opposing direction of the pair of stacked belts 42 The positions of 42, the first guide 43, the second guide 44, and the stopper body 53 are adjusted.

  Further, a detection mechanism 60 is disposed on the side of the pulley 36 of the transport belt 35 for detecting clogging of coins in the stacked portion 21 or for correcting the upper surface position of stacked coins in the stacked portion 21. . The detection mechanism 60 includes a detection lever 61, and a support shaft attached to a frame (not shown) at a base end of the detection lever 61 at an upper position upstream of the conveyance unit 20 in the conveyance direction from the position of the stacking unit 21. 62 is swingably supported. The front end side of the detection lever 61 is disposed above the stacking portion 21 at the side position of the pulley 36 of the transport belt 35. Accordingly, the detection lever 61 is disposed obliquely along the transport direction of the transport unit 20 from the proximal end to the distal end side. Further, a hole 63 that avoids interference with the shaft 37 of the pulley 36 is formed on the distal end side of the detection lever 61. Therefore, the pulley 36 and the detection lever 61 can swing independently.

  The lowering position of the tip of the detection lever 61 is a position spaced a predetermined distance from the upper surface of the passage bottom plate 32 of the transport path 31 and is regulated at a position above the peripheral surfaces of the pulley 36 and the transport belt 35. The interval is such that coins that are normally received by the stacking unit 21 from the transport unit 20 or coins that have bounced slightly do not touch or push up the detection lever 61 and are clogged in the stacking unit 21. Alternatively, the dimension is set such that the detection lever 61 is pushed up with the coins received in the stacking unit 21 from the transport unit 20 because the stacking space 49 on the uppermost coin of the stacking unit 21 is reduced. The detection lever 61 has a position where the lowering is restricted as a fixed position. From this fixed position, the detection lever 61 can swing upward with the support shaft 62 as a fulcrum, and is directed toward the fixed position by a biasing means such as a spring (not shown). It is energized.

  A detection unit (see FIG. 5) such as a switch or a sensor that detects that the detection lever 61 has swung upward from a fixed position is provided.

  Next, FIG. 5 shows a block diagram of the coin stacking device 23.

  Connected to the control unit 71 of the coin stacking device 23 is a conveyance motor 72 that rotates the conveyance belt 35 in the conveyance unit 20, a stopper drive unit 73 that drives a stopper, and a sensor 74 that includes an identification unit and a count sensor. In addition, in the stacking unit 21, a stacking motor 75 such as a stepping motor that rotationally drives the stacking belt, a detection unit 76 of the detection mechanism 60, and the like are connected, and a storage unit 77 that stores various data. Is connected.

  Then, the control unit 71 corrects the correction unit 78 so that the stacking support unit 47 is lowered by a predetermined correction lowering amount when the detection unit 76 of the detection mechanism 60 is turned on (detection of pushing up of the detection lever 61). And the function of the detection means 79 for detecting the width of the stacking space 49 of the stacking section 21. Data such as the number of corrections by the correction means 78 is stored in the storage unit 77.

  The detection means 79 detects the width of the stacking space by the number of corrections made during the stacking of a predetermined number of packaging unit coins.

  Further, the control unit 71 sets a lowering amount for lowering the stacking support unit 47 based on the size of the stacking space 49 detected in the past predetermined period detected by the detection unit 79, and puts coins into the stacking unit 21. The stacking support portion 47 has a function of lowering by a set lowering amount every time stacking is performed. That is, when it is detected that the stacking space 49 is wide in the past predetermined period, the lowering amount of the stacking support part 47 is set to be small, and it is detected that the stacking space 49 is narrow in the past predetermined period. If so, the descending amount of the stacking support portion 47 is set to be large.

  Next, the operation of the first embodiment will be described.

  First, the overall operation of the coin wrapping machine will be described.

  By setting the denomination to be packaged by the operation unit 14 of the coin wrapping machine, the transport unit 20, the stacking unit 21, and the packaging unit 22 are automatically adjusted according to the set denomination. That is, in the transport unit 20, the passage width between the passage side plates 33 and 34 is adjusted. In the stacking portion 21, the facing distance between the pair of stacking belts 42 is adjusted, and the stacking belt 42, the first guide 43, the first guide 43 in the direction orthogonal to the direction in which the pair of stacking belts 42 face each other is adjusted. The positions of the second guide 44 and the stopper body 53 are adjusted. In the packaging unit 22, the interval between the packaging rollers 25, the position of the winding needle 26, and the like are adjusted.

  Coins loaded in the hopper 12 of the coin wrapping machine are fed from the supply disk 18 to the feeding disk 19, and the coins are fed one by one from the feeding disk 19 to the transport unit 20.

  In the transport unit 20, the coins fed out from the feeding disk 19 are received between the passage side plates 33 and 34 on the passage bottom plate 32 of the conveyance path 31, and a conveyance belt (not shown) disposed on the upstream side in the conveyance direction and the conveyance The sheet is conveyed to the downstream side in the conveying direction by the conveying belt 35 disposed on the downstream side in the direction. Coins in the middle of conveyance are identified by the identification unit, and the coins sent out from the end of the conveyance unit 20 to the stacking unit 21 are counted by a count sensor.

  Coins fed from the end of the transport unit 20 are sequentially stacked in the stacking unit 21. When it is detected by the count sensor of the transport unit 20 that coins for a predetermined number of packaging units have been sent out, the subsequent coins are stopped by a stopper, and coins for a predetermined number of packaging units are stacked on the stacking unit 21.

  After the coins for the number of packaging units have been stacked on the stacking part 21, the stopper body 53 is moved in the outer diameter direction away from the space part 41, and then the stacking support part 47 is lowered to stack the stacked coins. Lower and transfer to the packaging unit 22 side.

  The wrapping unit 22 receives the stacked coins from the stacking unit 21, places the stacked coins between the three wrapping rollers 25, sandwiches and rotates them, and rotates the wrapping paper 16 of a predetermined length around the stacked coins. Wrapping around the surface, the upper and lower ends of the wrapping paper 16 are wound around the upper and lower end surfaces of the stacked coins with a pair of upper and lower wrapping needles 26, and wrapping coins are created.

  Next, the operation of the coin stacking device 23 will be described.

  First, the standard stacking operation will be described with reference to the flowchart of FIG.

  Prior to stacking of coins in the stacking section 21, the stacking support section 47 is arranged so that the stacking space 49 has an appropriate size.

  The coins fed from the transport unit 20 to the stacking space 49 are slidably in contact with the stacking support surface 48 of the stacking support unit 47 if the first stack is caused by the force from above by the transport belt 35 of the transporting unit 20. In the second and subsequent stacks, the top surface of the stacked coins is brought into contact with the stopper body 53 while sliding, and falls in the stacking space 49 without jumping out from the stacking section 21, and the stacking of the stacking support section 47 It is placed on the support surface 48 or the upper surface of the stacked coin. The coins placed on the stacking support surface 48 of the stacking support unit 47 or the top surface of the stacking coin are moved toward the transport unit 20 by the inclination of the stacking support surface 48 of the stacking support unit 47 or the top surface of the stacking coin. It tilts downward and is shifted to the guide roller 51 and the first guide 43.

  Each time coins are detected by the count sensor of the transport unit 20 and coins are stacked on the stacking unit 21 (step 1), the stacking motors 75 are driven to rotate the pair of stacking belts 42. The product support unit 47 is lowered by a preset lowering amount (step 2), and an appropriate size for stacking the next coin on the uppermost coin stacked on the stack support unit 47 is set. An accumulation space 49 is formed. For example, when the stacking support unit 47 is lowered by 0.25 mm by driving one pulse of the stacking motor 75 as a stepping motor, the descending amount of the stacking support unit 47 is 6 pulses of the stacking motor 75. By driving, the stacking support portion 47 is lowered by 1.5 mm. In this case, when 50 coins are stacked as one stacked coin (wrapped coin), the stack supporting portion 47 is lowered by 75 mm by driving 300 pulses of the stacking motor 75. Become.

  When coins are stacked on the stacking unit 21, it is determined whether the detection lever 61 is pushed up and the detection unit 76 is turned on (step 3). For example, when the stacking space 49 on the uppermost coin becomes narrow due to variations in the thickness of coins stacked on the stacking unit 21, the detection lever 61 is pushed up by the coins received from the transport unit 20 into the stacking unit 21. It will be. When the detection lever 61 is pushed up and the detection unit 76 is turned on, the stacking motors 75 are driven to rotate the pair of stacking belts 42 so that the stacking support unit 47 is set for a preset correction lowering amount. Is lowered (step 4), and correction for expanding the accumulation space 49 is performed. For example, when the stacking support part 47 is lowered by 0.25 mm by driving the accumulation motor 75 by one pulse, the correction support part 47 is driven by one pulse of the stacking motor 75. Lower by 0.25 mm.

  Thereafter, the coins sequentially fed out from the transport unit 20 are stacked on the stacking support unit 47 while repeating the above-described operation until, for example, 50 sheets of stacked coins are stacked (step 5). The storage unit 77 stores the number of corrections performed during the stacking of one coin.

  Subsequently, with respect to the setting of the descending amount of the stacking support portion 47 by the control unit 71, refer to the explanatory diagram of the relationship between the width of the stacking space in FIG. 7 and the coins entering the stacking space, and the flowchart in FIG. explain.

  As shown in FIG. 7 (a), when the stacking space 49 is narrow, the coins fed into the stacking space 49 from the transport unit 20 are caught by the pattern on the upper surface of the stacking coins, so that the stacking is disturbed. In addition, as shown in FIG. 7 (c), when the stacking space 49 is large, the coins fed into the stacking space 49 from the transport unit 20 enter the stacking space 49 straight and the opposite side Therefore, the stacking is likely to be disturbed and the coins are likely to stand up. Therefore, in any case, the coins may not be stacked normally without being disturbed. Therefore, in order to normally accumulate coins without being disturbed, it is necessary to appropriately maintain the area of the accumulation space 49 as shown in FIG. 7 (b).

  Then, in order to keep the stacking space 49 appropriately, the lowering amount of the stacking support part 47 is set as follows. Here, it is assumed that 50 sheets are stacked as one stacked coin, and the driving of the stacking motor 75 as a stepping motor is set to a standard value of 300 pulses / 50 sheets.

  Based on the data of the number of corrections for the last 10 stacked coins out of the data of the number of corrections for each previously stacked coin stored in the storage unit 77 by the detection means 79 of the control unit 71 (step 11). Then, it is determined whether the number of corrections in the average of the stacked coins is within a range of, for example, 10 to 39 as a predetermined range, or more or less, and the width of the stacked space 49 is detected (step 12).

  If the number of corrections is in the range of 10 to 39 with an average of one stacked coin, it is detected that the size of the stacked space 49 is appropriate. In this case, the descending amount of the stacking support portion 47 is set to a standard value (step 13). That is, the driving of the stacking motor 75 is set to a standard value of 300 pulses / 50 sheets.

  If the number of corrections is 40 times or more that is out of the range of 10 to 39 on the average of one stacked coin (step 14), it is detected that the stacked space 49 is narrow. In this case, correction is set so that the descending amount of the stacking support portion 47 is larger than the standard value (step 15). That is, the driving of the stacking motor 75 is set to +4 pulses as a standard value, and is set to 304 pulses / 50 sheets.

  If the number of corrections is 9 times or less that is out of the range of 10 to 39 on the average of one stacked coin, it is detected that the stacked space 49 is wide. In this case, correction setting is made so that the descending amount of the stacking support portion 47 is less than the standard value (step 16). That is, the driving of the stacking motor 75 is set to -4 pulses as a standard value and set to 296 pulses / 50 sheets.

  As described above, the coin stacking device 23 can set an appropriate lowering amount for lowering the stacking support portion 47 based on the size of the stacking space 49 in the past predetermined period. The coins entering the stacking space 49 from the transport unit 20 can be normally stacked.

  That is, when it is detected that the stacking space 49 is narrow in the past predetermined period, the stacking space 49 can be widened by setting the descending amount of the stacking support part 47 to be large. Can be appropriately sized. In addition, when it is detected that the stacking space 49 is wide in the past predetermined period, the stacking space 49 can be narrowed by setting the lowering amount of the stacking support portion 47 to be small. Can be appropriately sized.

  In addition, when it is detected that the detection lever 61 of the detection mechanism 60 is pushed up with coins stacked on the stacking portion 21, the stacking support portion 47 is corrected to be lowered by a predetermined correction lowering amount. Since the width of the stacking space 49 can be detected by the number of corrections during the stacking of a predetermined number of coins, the stacking of stacked coins can be performed without using a special mechanism for detection. Stack height can be detected.

  In addition, when it is detected that the stacking space 49 is wide in the past predetermined period, the lowering amount of the stacking support part 47 is not limited to be set to be small, and the lowering amount of the stacking support part 47 is set to 0 for the predetermined period. In this case, the coin space 49 can be narrowed by stacking coins within the predetermined period, and the stack space can be appropriately widened.

  In addition, when it is detected that the stacking space is wide in the past predetermined period, instead of setting the lowering amount of the stacking support part 47 to be small, the stacking support part 47 may be raised. In this case, the stacking space 49 can be narrowed immediately, and the stacking space 49 can be appropriately widened.

  In addition, since the data of the number of corrections is not accumulated at the start of operation, the lowering amount of the stacking support part 47 is set to a standard value (300 pulses / 50 sheets). However, in a predetermined period at the start of the operation, The lowering amount of the stacking support portion 47 may be set to a value (for example, 295 pulses / 50 sheets) smaller than the standard value (300 pulses / 50 sheets). As a result, the stacking space 49 becomes a descending amount that becomes narrower, prevents the stacking space 49 from widening and prevents the stacking abnormality, and accumulates data of the number of corrections. It can be corrected to an appropriate size.

  In addition, the past predetermined period is set to 10 stacked coins, and the descent amount of the stacked support portion 47 is set based on the correction number data for the 10 stacked coins. It is also possible to set the period of time as small as one or ten sheets, and to set the descending amount of the stacking support portion 47 based on the data of the number of corrections in these periods.

  For example, FIG. 9 shows an example in which the descending amount of the stacking support part 47 is set based on the data of the correction number of past 10 stacked coins.

  Based on the correction number data for the last 10 stacked coins among the past correction number data stored in the storage unit 77 by the detection means 79 of the control unit 71 (step 21), It is determined whether the number of corrections for 10 stacked coins is within a range of, for example, 2 to 8 or more or less, as a predetermined range, and the width of the stacked space 49 is detected (step 22).

  If there are 10 stacked coins and the number of corrections is in the range of 2 to 8, it is detected that the size of the stacked space 49 is appropriate. In this case, the descending amount of the stacking support portion 47 is set to a standard value (step 23). That is, the driving of the stacking motor 75 is set to 60 pulses / 10 sheets, which is a standard value, for example.

  If the number of corrections is 10 or more and 10 or more times out of the range of 2 to 8 (step 24), it is detected that the stacking space 49 is narrow. In this case, correction is set so that the descending amount of the stacking support portion 47 is larger than the standard value (step 25). That is, the driving of the stacking motor 75 is set to +1 pulse as a standard value, and is set to 61 pulses / 10 sheets.

  If the number of corrections is 10 times or less when the number of corrections is 10 or less and outside the range of 2 to 8, the stacking space 49 is detected to be wide. In this case, correction is set so that the descending amount of the stacking support portion 47 is less than the standard value (step 26). That is, the driving of the stacking motor 75 is set to −1 pulse as a standard value and set to 59 pulses / 10 sheets.

  As described above, by detecting the size of the stacking space 49 with the data of the correction number of the relatively small number of coins, it is possible to quickly cope with the change of the stacking space 49.

  Note that the detection means for detecting the width of the stacking space 49 is not limited to detecting from the data of the number of corrections, and the width of the stacking space 49 is directly detected by an optical sensor or an image sensor. May be.

  Next, FIG. 10 shows a second embodiment.

  In the first embodiment, the lowering amount of the stacking support portion 47 is set based on the size of the stacking space 49. In the second embodiment, a predetermined number of stacked coins are stacked. The stack height is detected, and the descending amount of the stack support portion 47 is set based on the stack height.

  The detection means 79 of the control unit 71 stacks a predetermined number of coins on the stacking support unit 47, and then pushes up the detection lever 61 to raise the stacking support unit 47 until the detection unit 76 detects it. Based on the raised position of the support portion 47, the stacked height L of the stacked coins is detected.

  That is, after a predetermined number of coins are stacked on the stacking support portion 47, the stacking support portion 47 is raised from that position. As the stacking support portion 47 is raised, the detection lever 61 is pushed up on the upper surface of the stacked coins, and the detection unit 76 detects it. Since the position of the stacking support part 47 can be grasped by the number of pulses given to the stacking motor 75, the stacking of stacked coins is based on the position of the stacking support part 47 raised to the position detected by the detection unit 76. The height L can be detected.

  If the detected stacking height L of the stacked coins is within a predetermined range, it can be determined that the stacking space 49 has an appropriate size, the descending amount of the stacking support portion 47 is set to a standard value, If the stacking height L of the detected stacked coins is shorter than the predetermined range, it can be determined that the stacking space 49 is wide, the descending amount of the stacking support portion 47 is set to be smaller than the standard value, If the stacked height L of the stacked coins is longer than the predetermined range, it can be determined that the stacked space 49 is narrow, and the descending amount of the stacked support portion 47 is set to be larger than the standard value.

  As described above, the coin stacking device 23 can set an appropriate lowering amount for lowering the stacking support portion 47 based on the stacking height L of the stacked coins, so that the stacking space 49 can be appropriately expanded. The coins entering the stacking space 49 from the transport unit 20 can be normally stacked.

  In addition, the stacked height of stacked coins can be detected using the existing detection mechanism 60 without using a special mechanism for detection.

  Next, FIG. 11 shows a third embodiment.

  In the second embodiment, in order to detect the stacking height L of the stacked coins, the upper and lower ends of the wrapping paper 16 are stacked with the upper and lower winding needles 26 in the stacking section 21 and the packaging section 22. The stacking height L of the stacked coins may be detected by the width of the upper and lower winding needles 26 when caulking to the end face of the coin.

  When the upper and lower ends of the wrapping paper 16 are caulked to the end face of the stacked coins with the upper and lower wrapping needles 26, the upper and lower wrapping needles 26 are in positions that are separated from the wrapping paper 16 in the vertical direction. The upper and lower ends of the wrapping paper 16 are caulked against the end surfaces of the stacked coins by approaching each other from the position. By detecting the width when the upper and lower winding needles 26 are closest to each other by a detection unit (not shown), the stacked height L of the stacked coins can be detected.

  In this way, in the coin stacking device 23, the stacked coins have the same width as the upper and lower winding needles 26 when the upper and lower ends of the wrapping paper 16 are crimped to the end surfaces of the stacked coins 26 with the upper and lower winding needles 26. Since the stacking height L can be detected, the stacking height of the stacked coins can be detected using the existing mechanism of the packaging portion 22 without using a special mechanism for detection.

  In addition, as a detection means for detecting the stacked height of stacked coins, the stacked coin stacked height may be directly detected by an optical sensor or an image sensor.

  The present invention is used for a coin stacking device such as a coin wrapping machine.
