Is pushed up to a predetermined packaging position of the upper coin packaging part 25. By placing the accumulated coins on the coin placing portion 41, the accumulated coins in the inclined state become horizontal in the coin wrapping portion 25. The position of the accumulated coins raised to the packaging position of the coin wrapping portion 25 by the support rod 40 is such that the center in the vertical direction at the packaging position of the coin wrapping portion 25 coincides with the center in the vertical direction that is the accumulation direction of the accumulated coins. It is stipulated in. Therefore, the accumulated coins are arranged at the packaging position of the coin wrapping portion 25 with reference to the center in the accumulation direction, regardless of the denominations having different lengths in the accumulation direction.

  The accumulation bottom member 30 on which the accumulation roller 36 and the support rod 40 are disposed is supported by the guide member 42 so as to be movable in an oblique direction with respect to the coin C conveying direction and the passage width direction, and is moved by the denomination setting means 18. Thus, the positions of the accumulation roller 36 and the support rod 40 are adjusted to positions corresponding to the packaging denomination.

  As shown in FIGS. 1 to 4, the upper part of the coin accumulating unit 24 has a packaging processing period from the accumulation of the coins C in the coin accumulating unit 24 to the completion of the packaging of the accumulated coins in the coin wrapping unit 25. In addition, except for a predetermined period during the packaging process period, coin support means 44 is provided that presses the upper surface of the coin C and maintains the accumulation state.

  The coin support means 44 has a coin presser 45 that can move in the stacking direction in the coin stacking unit 24 and the coin wrapping unit 25 and that contacts the upper surface of the coin C and presses it downward. The coin presser 45 has a substantially cylindrical shape having a diameter smaller than that of the coin C, and the lower surface includes an inclined portion 46 that presses against the upper surface of the coin C accumulated in an inclined state by the coin accumulating portion 24, and the coin wrapping portion 25. A horizontal portion 47 is formed in contact with and pressed against the coins C stacked horizontally.

  The coin presser 45 is supported by a sliding member 49 via a support member 48 passed between the packaging rollers 27 and 29, and the sliding member 49 is interposed between the top plate 31 and the bottom plate 50 of the coin packaging device 11. A plurality of guide shafts 51 provided in parallel to the axes of the packaging rollers 27, 28 and 29 are attached so as to be slidable in the accumulation direction. Below the sliding member 49, a weight 52 is attached to a plurality of guide shafts 51 so as to be slidable in the vertical direction, and the sliding member 49 and the weight 52 are connected by a spring 53.

  As shown in FIGS. 1 and 2, a detecting means 56 for detecting the stacking height of the coins C from the position in the stacking direction of the coin presser 45 is provided. The detection means 56 includes a potentiometer 58 having a detection shaft 57, and a detection lever 59 attached to the detection shaft 57 of the potentiometer 58 and rotating around the detection shaft 57. An abutting portion 60 is provided in which the upper surface of the sliding member 49 rising integrally with the coin presser portion 45 abuts and is pushed up. The potentiometer 58 outputs a voltage corresponding to the rotation angle of the detection lever 59 and is supported by the bracket 61 at a fixed position with respect to the top plate 31 and the like. A spring 62 is attached between the other end of the detection lever 59 and the bracket 61 so that the contact portion 60 at one end of the detection lever 59 is urged toward the upper surface of the sliding member 49.

  Also, as shown in FIGS. 1 and 2, a packaging sheet supply unit 63 for supplying a packaging sheet P to be wound around the peripheral surface of the supplied accumulated coins between the packaging rollers 27, 28, 29 of the packaging means 26 and the accumulated coins. It has. In this packaging sheet supply unit 63, the packaging sheet P is cut into a predetermined length that wraps around the circumferential surface of the accumulated coins, for example, twice or more, and the center in the width direction (vertical direction) of the packaging sheet P is coin wrapping. The packaging sheet P is supplied so as to coincide with the center in the accumulation direction of the accumulated coins arranged in the portion 25. The width of the wrapping sheet P is, for example, 110 mm, and is formed wider than an accumulation length of 90 mm in which 50 coins of 500 yen having the largest thickness are accumulated. Therefore, the upper and lower ends of the wrapping sheet P wound around the circumferential surface of the accumulated coin protrude from both end surfaces of the accumulated coin, and even in the case of a 500 yen coin having the smallest protruding dimension, (110−90) / 2 = It is about 10 mm.

  Further, as shown in FIGS. 3 and 4, above the coin stacking portion 24 and on the upper side of the coin wrapping portion 25, on the upper surface of the stacked coins disposed at the wrapping position of the coin wrapping portion 25 by the support rod 40. A moving means 65 for moving the coin presser 45 of the coin support means 44 in contact in the up and down direction, which is the stacking direction, is arranged so as to be separated from or contact the upper surface of the stacked coins.

  The moving means 65 has a lever 66, and on the side surface of the lever 66, a push roller 67 is rotatably supported at one end, and a cam roller 68 is rotatably supported at the other end. An intermediate portion of the lever 66 is pivotally supported by an attachment member 69, and the attachment member 69 is fixed to a support shaft 70 provided in parallel with the axes of the packaging rollers 27, 28, and 29. The lever 66 is longer on the side of the pressing roller 67 than the mounting member 69 and has a center of gravity on the side of the pressing roller 67, so that the end of the pressing roller 67 is automatically lowered by gravity. Has been. Alternatively, the lever 66 is biased by a spring so that one end of the lever 66 is lowered.

  The support shaft 70 can rotate integrally with the mounting member 69 and the lever 66 around the shaft, and the pushing roller 67 at one end of the lever 66 can overlap the support member 48 in the vertical direction. It is possible to rotate and move to a position and a retracted position located on the side of the support member 48 without overlapping the support member 48 in the vertical direction. The rotational position of the support shaft 70 is switched by driving means such as a motor or a solenoid (not shown).

  A cam 72 that rotates about a horizontal cam shaft 71 is disposed above the cam roller 68, and the cam roller 68 is in contact with a cam surface 73 that is a peripheral surface of the cam 72. As described above, the cam roller 68 is always in contact with the cam surface 73 of the cam 72 due to the mass balance of the lever 66 or the biasing by the spring. Even if the lever 66 rotates between the operating position and the retracted position, the contact state between the cam roller 68 and the cam 72 is maintained.

  On the cam surface 73 of the cam 72, a fixed position 73a, a first denomination position 73b, a second denomination position 73c, and a third denomination position 73d are formed, and the distance from the cam shaft 71 is set at a fixed position 73a. Is the smallest, and the distance from the cam shaft 71 increases in the order of the first denomination position 73b, the second denomination position 73c, and the third denomination position 73d.

  In the state where the cam roller 68 is in contact with the fixed position 73a of the cam surface 73 of the cam 72, the push roller 67 is the accumulated coin in any denominated accumulated coin disposed at the packaging position of the coin packaging portion 25. Is located at a fixed position lower than the position of the support member 48 with which the coin presser portion 45 is in contact with the upper surface of the roller, so that the push roller 67 is supported by the rotation of the lever 66 by the support shaft 70. It is possible to move between an operating position for entering the lower side of 48 and a retracted position for retracting to the side of the support member 48.

  When the push roller 67 is in the operating position where it enters the lower side of the support member 48, the cam 72 rotates, and is in one of the first denomination position 73b, the second denomination position 73c, and the third denomination position 73d. When the cam roller 68 abuts, the lever 66 swings so that the push roller 67 side of one end rises, and the push roller 67 abuts the lower surface of the support member 48 and the first denomination and the second denomination of the accumulated coins. The coin presser 45 is pushed upward by a distance corresponding to either the denomination or the third denomination, and the coin presser 45 is separated from the upper surface of the accumulated coin by a predetermined distance.

  At this time, the rising distance of the push roller 67 due to the contact between the first denomination position 73b, the second denomination position 73c and the third denomination position 73d of the cam 72 and the cam roller 68 is the first denomination of the accumulated coins. , Respectively corresponding to the second denomination and the third denomination.

  As shown in FIG. 5, the first denomination includes 1 yen, 5 yen and 10 yen in which the thickness of the coin C is 1.5 mm and the accumulation length of 50 coins C is 75 mm. The seeds include 50 yen and 100 yen with a thickness of 1.7 mm and the accumulation length of 50 coins C accumulated to 85 mm, and the third denomination has a thickness of 1.8 mm and 50 coins C accumulated. 500 yen with an integrated length of 90 mm is included.

  As described above, the accumulated coins are arranged at the packaging position of the coin wrapping portion 25 with reference to the center of the accumulation direction regardless of the denominations having different lengths in the accumulation direction. Based on one denomination, the second denomination position is 5 mm higher, which is the difference of the accumulation length / 2 with the first denomination, and the third denomination position is the difference of the accumulation length / 2 with the first denomination. Some 7.5mm higher.

  Therefore, when the accumulated coin is the first denomination, for example, the distance between the pressing roller 67 positioned at a fixed position and the lower surface of the support member 48 is 6 mm, and the coin presser 45 is moved upward from the upper surface of the accumulated coin. Assuming that the cam roller 68 is separated from the fixed position 73a of the cam 72 by the first denomination position 73b, the push roller 67 is lifted by 6 + 3 = 9 mm.

  Similarly, when the accumulated coin is the second denomination, the difference in accumulation length / 2 with respect to the first denomination is 5 mm, so that the second denomination position 73c comes into contact with the cam roller 68 from the fixed position 73a of the cam 72. As a result, the pushing roller 67 rises by 6 + 3 + 5 = 14 mm.

  Similarly, when the accumulated coin is the third denomination, the difference in accumulation length / 2 from the first denomination is 7.5 mm, so that the cam roller 68 has the third denomination position 73d from the fixed position 73a to the cam 72. As a result of the contact, the pushing roller 67 rises by 6 + 3 + 7.5 = 16.5 mm.

  In addition, the distance which separates the coin presser part 45 upward from the upper surface of the stacked coins is not limited to 3 mm, but may be any distance as long as the coin presser part 45 does not contact the upper surface of the stacked coins being packaged. Preferably, the distance from the end face of the accumulated coin to the end of the packaging sheet P wound around the accumulated coin and protruding from the end face of the accumulated coin, that is, (the width of the packaging sheet−the length of the accumulated coin) / 2 or less. By doing so, even if the coin presser part 45 is separated from the upper surface of the accumulated coins during packaging, the end of the packaging sheet P and the coin presser part 45 can prevent the coins from popping out. In addition, the distance by which the coin presser 45 is separated upward from the upper surface of the accumulated coins may be a constant value for all denominations or may be set to a different value for each denomination.

  Moreover, as shown in FIG. 6, the wrapping means 26 is wound around the circumferential surface of the accumulated coins, and the both ends of the packaging sheet P protruding from the end surface of the accumulated coins are wound around the end surfaces of the accumulated coins. Means 80 are provided. The winding means 80 has a pair of winding members 81, and a support portion 82 that supports each of the winding members 81 is supported by a support shaft 83 so as to be slidable in the vertical direction that is the stacking direction. A cam shaft 85 having a plurality of cams 84 attached thereto is rotatably disposed on the side of the support shaft 83, and each winding member 81 is moved in the stacking direction by each arm 86 driven by each cam 84 of the cam shaft 85. To do. One end of each arm 86 is rotatably supported at a fixed position by a shaft 87, the other end is connected to each support portion 82, and an intermediate portion abuts on each cam 84 and is driven.

  Then, one wrapping operation of the packaging sheet P is completed by one rotation of the camshaft 85, and at the initial retracted position, the pair of winding members 81 are located between the three wrapping rollers 27, 28, 29. Is located at a retracted position that is laterally disengaged from each other, and at positions separated from each other in the vertical direction from both ends of the packaging sheet P wound around the accumulated coins. As the camshaft 85 starts to rotate, the pair of winding members 81 moves to the caulking position, which is the upper and lower region of the packaging sheet P wound around the accumulated coins, between the three packaging rollers 27, 28, 29, and the pair of winding members 81 Three wrapping rollers after the pair of wrapping members 81 move up and down after the wrapping member 81 moves close to each other and wraps the wrapping sheet P around the end face of the accumulated coins, and after the wrapping of the wrapping sheet P is completed. It is configured to retreat between 27, 28 and 29 and return to the initial retreat position.

  Further, as shown in FIG. 7, the denomination setting means 18 includes a first adjustment cam 91 that adjusts the position of the movable passage member 16 according to the denomination, and the positions of the accumulation roller 36 and the support rod 40 as denominations. The second adjusting cam 92 that adjusts to the above is provided. Further, the position of the packaging rollers 27 and 28 is also adjusted by the denomination setting means 18 according to the denomination.

  Further, the bottom bottom member 30 below the coin stacking portion 24 and the coin wrapping portion 25 is retracted laterally from the lower position of the coin stacking portion 24 and the coin wrapping portion 25 by the retracting means 95, and the formed wrapping coins and excess or deficiency are formed. It is possible to release the accumulated coins generated in the downward direction. The retracting means 95 includes a retracting motor 96, and the integrated bottom member 30 is moved via the link 97 by driving the retracting motor 96.

  FIG. 8 shows a block diagram of the coin wrapping apparatus 11. The control unit 101 that controls the coin wrapping apparatus 11 inputs signals from the passage detection sensor S1 and the counting sensor S2 of the conveyance path 13, the potentiometer 58 of the detection means 56, and the like, and conveys the rotary disk 12 and the conveyance belt 17 The drive unit 102, the stopper drive unit 103 that drives the stopper 21, the drive unit of each component of the packaging unit 26, the drive unit of each component of the moving unit 65, the retraction motor of the retraction unit 95, and the like are controlled. Further, the control unit 101 has a reference length in the accumulation direction of the denominated coins C corresponding to the output of the potentiometer 58 in order to detect the accumulation height of the coins C from the output of the potentiometer 58 of the detection means 56. A storage unit 104 that stores the reference integrated height is connected.

  The control unit 101 controls the rotation speed of the wrapping rollers 27, 28, 29 of the wrapping means 26, and rotates the wrapping sheet P at a low speed of, for example, about 100 to 200 rpm during the winding operation of the wrapping sheet P around the stacked coins. During the caulking operation of the packaging sheet P by 81, it is rotated at a high speed of, for example, about 2000 rpm, and the rotation speed is continuously switched.

The confirmation of the excess or deficiency of the number of coins is performed at the timing before packaging when the accumulated coins are moved to the packaging position of the coin packaging unit 25, and at the timing after completion of packaging when the packaging of the accumulated coins is completed.

  Next, the operation of the coin wrapping apparatus 11 will be described.

  First, the overall operation of the coin wrapping apparatus 11 will be described. The description of the operation related to the control of the coin support means 44 is omitted in the description of the overall operation and will be described later.

  The denomination to be packaged is set by the denomination setting means 18, and the passage width of the transport passage 13, the positions of the accumulation roller 36 and the support rod 40, and the positions of the packaging rollers 27 and 28 are adjusted.

  First, in the stacking process, among the coins C fed into the rotating disk 12, coins C having a diameter smaller than the coin diameter of the packaging denomination are sent one by one to the conveying path 13 by the centrifugal force due to the rotation of the rotating disk 12, and conveyed. It is conveyed by the belt 17. The coin C having a smaller diameter than the wrapping denomination falls from the exclusion port 19, and only the coin C of the wrapping denomination is transported from the downstream side of the transport path 13 to the coin accumulating unit 24.

  When the coin C conveyed to the coin stacking unit 24 is detected and counted by the counting sensor S2 and a predetermined number of coins C are detected, the passage 21 of the coin C is confirmed by the passage detection sensor S1, and then the stopper 21 is pressed. The coin C following the predetermined number of accumulated coins C is stopped by entering the transport path 13.

  As shown in FIG. 2, in this stacking process, the coin stacking unit 24 pushes the edge portion 38 a of one tooth portion 38 of the stacking roller 36 with the coin C transported from the transport path 13 to stack the stacking roller 36. And the rear end of the coin C in the conveyance direction is raised from the top surface of the passage bottom surface member 14 and the accumulation bottom surface member 30 of the conveyance passage 13 by the gradually increasing portion 38b of the tooth portion 38 in the rotation direction of the accumulation roller 36, Subsequently, the leading end of the coin C to be transported is inserted into the lower side of the lowest coin C in the coin stacking unit 24 to sequentially stack the coins C. At this time, the coin presser 45 is brought into contact with the upper surface of the uppermost coin C and pressed downward to maintain the accumulated state.

  After completing the accumulation of the coins C corresponding to the predetermined number of sheets conveyed from the conveyance passage 13 by the coin accumulating unit 24, the support rod 40 is raised as shown in FIG. Raise to the packaging position. At this time, the coin presser 45 rises integrally with the accumulated coins, and the upper surface of the sliding member 49 of the coin presser 45 comes into contact with the contact 60 of the detection lever 59 of the detection means 56 and pushes it up. Then, the detection shaft 57 of the potentiometer 58 is rotated. The potentiometer 58 outputs a voltage signal corresponding to the rotational position of the detection shaft 57 to the control unit 101.

  The control unit 101 detects the accumulated height of the accumulated coins from the output of the potentiometer 58, and compares the detected accumulated height with the reference accumulated height stored in the storage unit 104 to confirm whether the number of coins is excessive or insufficient.

  If there is an excess or deficiency in the number of coins, the packaging of the accumulated coins is stopped, and after the support rod 40 is lowered, the accumulation bottom member 30 is retracted from the lower part of the coin accumulation unit 24 by the retracting means 95. Then, the accumulated coins are discharged and collected from the lower part of the opened coin accumulation unit 24. Thereafter, the accumulation bottom member 30 is returned to the lower side of the coin accumulation unit 24 by the retracting means 95, and the packaging operation starting from the next coin accumulation is resumed.

  If there is no excess or deficiency in the number of coins in the confirmation before packaging, the packaging process by the packaging means 26 is started. First, in the winding process during the packaging process, the accumulated coins C are sandwiched between the packaging rollers 27, 28, and 29. While rotating at a low speed, the packaging sheet P cut to a predetermined length by the packaging sheet supply unit 63 is supplied between the packaging rollers 27, 28, 29 and the accumulated coins, and the packaging sheet P is placed on the circumferential surface of the accumulated coins. For example, two or more (double) winding is performed. Further, in the caulking process in the packaging process, the accumulated coins are rotated at high speed by the packaging rollers 27, 28, 29, and the both ends of the packaging sheet P protruding from the end surface of the accumulated coins are collected by the pair of winding members 81. It is wound around the end face and caulked to create a wrapping coin called bar metal.

  After the packaging is completed, after the rotation of the packaging rollers 27, 28, 29 is stopped, the control unit 101 uses the coin press part 45 that contacts the upper surface of the packaging coin in the inspection process, as before the packaging. Check if there are too many coins. That is, the control unit 101 detects the accumulated height of the coins C from the output of the potentiometer 58 of the detecting means 56, compares the detected accumulated height with the reference accumulated height stored in the storage unit 104, and determines the number of coins. Check for excess and deficiency.

  If an excess or deficiency in the number of coins is detected during packaging, the packaging operation is stopped, and after the support rod 40 is lowered, the accumulation bottom member 30 is retracted from the lower part of the coin accumulation unit 24 by the retracting means 95. Then, the accumulated coins C in the package are discharged from the lower portion of the opened coin accumulation unit 24 and collected. Thereafter, the accumulation bottom member 30 is returned to the lower side of the coin accumulation unit 24 by the retracting means 95, and the packaging operation starting from the next coin accumulation is resumed.

  If an excess or deficiency is detected in the number of coins after packaging is completed, the support bottom 40 is lowered and then the collecting bottom member 30 is retracted from the lower part of the coin accumulating unit 24 by the retracting means 95 to open the coin accumulating unit opened. The wrapping coins are discharged from the bottom of 24 and collected. Thereafter, the accumulation bottom member 30 is returned to the lower side of the coin accumulation unit 24 by the retracting means 95, and the packaging operation starting from the next coin accumulation is resumed.

  If there is no excess or deficiency in the number of coins in the confirmation after the completion of packaging, the stacking bottom member 30 is retracted from the lower portion of the coin stacking portion 24 by the retracting means 95 after the support rod 40 is lowered, and the coin stacking portion 24 opened. The wrapping coins are discharged from the lower part of the container and sent to a predetermined place for subsequent processing such as storage. Thereafter, the accumulation bottom member 30 is returned to the lower side of the coin accumulation unit 24 by the retracting means 95, and the packaging operation starting from the next coin accumulation is started.

  Next, operations related to the control of the coin support means 44 will be described.

  As shown in FIG. 9, Example 1 and Example 2 are shown as an example of the operation | movement regarding control of the coin support means 44. FIG.

  First, in the first embodiment, during the process of accumulating coins C in the coin accumulating unit 24, the coin presser 45 is brought into contact with the upper surface of the uppermost coin C and pressed downward to maintain the accumulated state of the coins C. In addition, the winding member 81 is located at the retracted position retracted from between the packaging rollers 27, 28, and 29.

  During the wrapping process of the wrapping sheet P following the stacking process, the stacked coins are sandwiched between the packing rollers 27, 28, and 29 and rotated at a low speed, and then wrapped between the packing rollers 27, 28, 29 and the stacked coins. The packaging sheet P cut into a predetermined length is supplied by the sheet supply unit 63, and the packaging sheet P is wound around the circumferential surface of the accumulated coins. During this winding process, the coin presser portion 45 abuts against the upper surface of the accumulated coins and presses downward, preventing the accumulation of the accumulated coins from being disturbed with the winding of the packaging sheet P, and the winding member 81 is located at the retracted position. At this time, the coin presser portion 45 is in contact with the upper surface of the accumulated coins, but the rotational speed of the accumulated coins is low, so the coin presser portion 45 and the upper surface of the accumulated coins rub, but the coin C is damaged. It does not lead to.

  During the caulking process of the packaging sheet P following the winding process, the pair of winding members 81 are moved to the caulking position which is the upper and lower regions of the packaging sheet P wound around the accumulated coins between the packaging rollers 27, 28 and 29. While the accumulated coins are rotated at high speed by the wrapping rollers 27, 28 and 29, the pair of winding members 81 are moved toward each other so that both end portions of the wrapping sheet P protruding from the end surfaces of the accumulated coins are wound on the end surfaces of the accumulated coins. Squeeze. During the caulking process, the coin presser 45 of the coin support means 44 is raised by the moving means 65 and separated from the upper surface of the accumulated coins, so that the coin presser 45 and the upper surface of the accumulated coins rotating at high speed are rubbed. It is possible to prevent and damage the surface of the coin C.

  During the caulking step, the accumulated coins C are firmly clamped by the packaging sheet P wound twice or more (double) in the winding step, and the accumulated state of the accumulated coins is stably held. The upper winding member 81 is located in the upper region facing the upper surface of the accumulated coins, and serves to prevent the coin C from jumping out from the upper end of the packaging sheet P. The coin presser 45 is separated from the end surface of the accumulated coins. The size of the sheet C is smaller than the dimension of the packaging sheet P protruding from the end face of the accumulated coins, that is, (the width of the packaging sheet−the length of the accumulated coins) / 2 or less, and the coin C is prevented from popping out from the upper end of the packaging sheet P. Even if the coin presser 45 is moved away from the upper surface of the accumulated coins, for example, the coin C from the upper end of the packaging sheet P pops out or the accumulation of the coins C is not disturbed. It can occupy the end or involving the upper surface of the stacked coins.

  When the caulking process is completed, the rotation of the packaging rollers 27, 28, 29 and the packaging coins is stopped, and the pair of winding members 81 are retracted from between the packaging rollers 27, 28, 29.

  In the inspection process after the caulking process, the coin holding part 45 of the coin supporting means 44 is lowered by the moving means 65, and the coin holding part 45 is brought into contact with the upper surface of the wrapping coin. Thereby, the control unit 101 detects the accumulated height of the wrapping coins from the output of the potentiometer 58, and compares the detected accumulated height with the reference accumulated height stored in the storage unit 104 to determine whether the number of coins is excessive or insufficient. Check.

  Next, Example 2 will be described. Here, only differences from the first embodiment will be described, but the other points are the same as those of the first embodiment.

  During the period from the start of the winding process of the packaging sheet P to the completion of the caulking process, the coin presser 45 of the coin support means 44 is raised by the moving means 65 and separated from the upper surface of the accumulated coins. Thereby, it is possible to prevent rubbing between the coin pressing portion 45 and the upper surface of the accumulated coin that rotates in both the winding step and the caulking step, and to reliably prevent the surface of the coin C from being damaged.

  In this case, the stacked coins 27 are sandwiched by the three wrapping rollers 27, 28, 29 and are held in a stable stacked state. Therefore, even if the coin presser 45 is separated from the upper surface of the stacked coins, The coins C can be packaged without popping out or disturbing the accumulation of the coins C.

  In the winding process, the accumulated coins are rotated at a low speed by the packaging means 26, and in the caulking process, the accumulated coins by the packaging means 26 are rotated at a high speed. It can be understood that the portion 45 is raised and separated from the upper surface of the accumulated coins. The damage of the coin C due to the contact with the coin presser 45 is more likely to occur when the accumulated coins rotate at a high speed. Therefore, when the accumulated coins rotate at a high speed, the coin retainer 45 is separated from the upper surface of the accumulated coins. The surface of the coin C can be prevented from being damaged.

  Further, in the winding process, the coin holding part 45 of the coin supporting means 44 is moved by the moving means 65 during the period from the time when the first sheet of the packaging sheet P is wound around the circumferential surface of the accumulated coins to the completion of the caulking process. May be raised and separated from the upper surface of the accumulated coins. In this case, packaging can be performed without damaging the surface of the coin C as much as possible while stabilizing the accumulation state of the coin C.

  Alternatively, except at the beginning and end of the caulking process, the coin holding portion 45 of the coin support means 44 is raised by the moving means 65 only during the period when the high speed rotation of the packaging rollers 27, 28, 29 and the accumulated coins is stabilized. Alternatively, the accumulated coins may be separated from the upper surface. In this case, it is possible to reliably prevent the coin C from popping out due to the influence of the rotation of the accumulated coins switching at high speed.

  Thus, in order to move the coin support means 44 away from the end face of the accumulated coins according to a predetermined period according to the processing step during packaging by the packaging means 26 and the rotational speed of the accumulated coins by the packaging means 26, the coin C Coins C can be packaged without damaging the surface as much as possible.

  In particular, in order to separate the coin presser 45 of the coin support means 44 from the end face of the accumulated coins at least for a predetermined period during the caulking process by the winding member 81 or when the rotational speed of the accumulated coins by the packaging means 26 is equal to or higher than a predetermined value. The coin can be wrapped without damaging the surface of the coin C as much as possible.

  Even if the coin holding part 45 of the coin supporting means 44 is separated from the end face of the accumulated coins until the packaging is completed, after the packaging by the packaging means 26 is completed, the coin holding part 45 of the coin supporting means 44 is By making contact with the end face, it is possible to detect the excess or deficiency of coins based on the detection of the detection means 56. Thereby, even if the coin C pops out during packaging, it can be grasped and dealt with that the number of coins is insufficient in the packaging coin.

  In addition, when the rotational speed becomes low just before the caulking process is finished, the coin presser part 45 may be brought into contact again in accordance with the timing at which the rotational speed becomes slow, even before the caulking process is completed.

  The coin wrapping apparatus 11 is not limited to the one that accumulates the coins C in the vertical direction as in the above-described embodiment, but can be applied to one that accumulates in the horizontal direction or in an oblique direction. For this reason, the coin support means 44 is not limited to the one that contacts the upper surface of the accumulated coin or the wrapping coin, but may be any one that contacts the end face of the accumulated coin or the wrapping coin.
