  The wrapping paper supply unit 12 includes a roll support unit 16 that rotatably supports the wrapping paper roll S1. The wrapping paper roll S1 is formed in a roll shape by winding a long sheet of wrapping paper S made of paper or a resin film. The wrapping paper supply unit 12 has a first insertion guide plate 21 and a second insertion guide plate 22 on the side of the roll support unit 16.

  Further, the wrapping paper supply unit 12 has a paper feed roller 23 and an auxiliary roller mechanism 24 on the opposite side of the first insertion guide plate 21 and the second insertion guide plate 22 from the roll support unit 16. The auxiliary roller mechanism 24 includes an arm 26 that rotates around a shaft portion 25, an auxiliary roller 27 that is rotatably supported at the tip of the arm 26, and a spring member 28 that biases the arm 26. . The spring member 28 urges the arm 26 so as to press the auxiliary roller 27 against the paper feed roller 23.

  The wrapping paper S fed out from the wrapping paper roll S1 is inserted between the first insertion guide plate 21 and the second insertion guide plate 22 and sandwiched between the paper feed roller 23 and the auxiliary roller 27. The paper feed roller 23 and the auxiliary roller 27 pull out the wrapping paper S from the wrapping paper roll S1 supported by the roll support portion 16 and send it out toward the wrapping portion 13 as a supply destination.

  The wrapping paper supply unit 12 includes a first supply guide plate 31 disposed on the paper feed roller 23 side, and a curved second supply guide disposed on the opposite side of the first supply guide plate 31 from the paper feed roller 23. It has the board 32 and the 3rd supply guide plate 33 provided in parallel by the edge part on the opposite side to the 1st supply guide plate 31 of the 2nd supply guide plate 32. As shown in FIG.

  The wrapping paper S sent out from the paper feed roller 23 and the auxiliary roller 27 as described above is guided in a curved shape by the first supply guide plate 31 and the second supply guide plate 32, and the second supply guide plate 32 and the second supply guide plate 32. 3 is further fed toward the packaging unit 13 through the space between the three supply guide plates 33. The wrapping paper supply unit 12 has a cutter 35. When the wrapping paper S is drawn into the wrapping unit 13 with the paper feed roller 23 stopped, the wrapping paper S comes into contact with the cutter 35 and is cut.

  The packaging unit 13 is the same as the conventional one having three packaging rollers 37, 37, 37 along the vertical direction. In the wrapping unit 13, the unillustrated stacked coins stacked in the vertical direction are disposed between the packing rollers 37, 37, 37, and the stacked coins are sandwiched between both sides in the stacking direction as shown in FIG. It is sandwiched between the members 38 and 38. The wrapping paper 13 is supplied to the wrapping section 13 from the wrapping paper supply section 12 shown in FIG. The wrapping unit 13 rotates the wrapping rollers 37, 37, 37 while sandwiching the wrapping paper S with the accumulated coins so as to wind the wrapping paper S around the circumferential surface of the accumulated coins, and a pair of upper and lower clamping claws shown in FIG. 39 and 39 crimp the upper and lower ends of the wrapping paper S. Thus, the packaging part 13 produces the wrapping coin C formed by winding the wrapping paper S around the circumferential surface of the accumulated coins.

  The packaging unit 13 includes, for example, an interval detection sensor 40 that detects the interval between the holding members 38, 38, and the control device 15 determines whether the detection result of the interval detection sensor 40 and the reference thickness of the coin type are Detects excess or deficiency of coins. And the control apparatus 15 determines with the packaging coin C with excess and deficiency being abnormal, and determines with the packaging coin C without the excess and deficiency of coins being normal.

  The lower part of the wrapping coin handling machine 11 is guided by a guide 45 that guides the falling movement of the wrapping coins C produced one by one in the wrapping part 13 and fed out from the wrapping part 13 by gravity, and the guide 45. An accommodating portion 46 that accommodates the wrapping coin C so as to be removable from the machine and a printing device 47 that performs printing on the wrapping coin C being conveyed from the packaging portion 13 toward the accommodating portion 46 by a guide 45 are provided. .

  The guide 45 has an upstream guide portion 50 disposed on the upstream side in the transport direction of the wrapping coin C (hereinafter referred to as upstream in the transport direction), that is, on the packaging portion 13 side, and a downstream side in the transport direction of the wrapping coin C (hereinafter referred to as transport). A downstream guide portion 51 disposed on the housing portion 46 side.

  As shown in FIG. 3, the upstream guide portion 50 includes a pair of flat plate-like upstream side wall portions 52 and 53 that are vertically arranged and parallel to each other, and lower end edges of the pair of upstream side wall portions 52 and 53. 4 has a pair of plate-like upstream bottom portions 54 and 55 shown in FIG. 4 that extend so as to be close to each other and are connected to end edges on the extending tip side. The pair of upstream bottom portions 54 and 55 have a V-shaped cross section so as to be positioned on the lower side as they are closer to each other, and both are inclined so as to be positioned on the lower side. Here, assuming that the direction connecting the upstream side wall portions 52 and 53 is the width direction of the guide 45 (hereinafter referred to as the guide width direction), the upstream bottom portions 54 and 55 are such that the boundary line O is the center in the guide width direction. And parallel to the upstream side wall portions 52 and 53. The upstream bottom portions 54 and 55 are parallel to the surface orthogonal to the upstream side wall portions 52 and 53 and have the same inclination angle with respect to the surface including the boundary line O.

  Since the upstream side bottom portions 54 and 55 have such a shape, the upstream side guide portion 50 causes the cylindrical wrapping coin C to be brought into line contact with both the upstream side bottom portions 54 and 55 by gravity and upstream. It is closest to the boundary line O (center in the guide width direction) of the side bottom portions 54 and 55, and the posture is set along the extending direction (conveying direction) of the boundary line O. And the upstream guide part 50 is guided so that the wrapping coin C may move in the extending direction of the boundary line O in this state.

  The downstream side guide part 51 extends vertically so as to be close to each other from the downstream side wall parts 56, 57 that are erected vertically and are parallel to each other, and the lower end edge parts of the downstream side wall parts 56, 57. Downstream end portions 58 and 59 where the end edges are connected to each other, and an end wall portion 60 erected vertically and positioned on the most downstream side in the transport direction.

  The downstream side wall 56 is shorter in the transport direction than the downstream side wall 57. The downstream side wall portion 56 is arranged on the same plane as the one upstream side wall portion 52 and is continuous with the one upstream side wall portion 52. The downstream side wall 57 is arranged in the same plane as the other upstream side wall 53, and is continuous with the other upstream side wall 53.

  The downstream bottom 58 extending from the lower end edge of the downstream side wall 56 is continuous with one upstream bottom 54, and the downstream bottom 59 extending from the lower end edge of the downstream side wall 57 is the other bottom The upstream bottom 55 is continuous. The downstream bottom 58 is shorter in the transport direction than the downstream bottom 59. The downstream bottoms 58 and 59 have a V-shaped cross section so that the range in the transport direction connected to each other is located on the lower side toward the close side, and both have a constant height in the transport direction. That is, when viewed from the side in the horizontal direction, the upstream guide portion 50 as a whole is inclined with respect to the horizontal, and the downstream guide portion 51 is disposed horizontally as a whole.

  The end wall portion 60 extends perpendicularly to the downstream side wall portion 57. Since the downstream side wall portion 56 and the downstream side bottom portion 58 are shorter than the downstream side wall portion 57 and the downstream side bottom portion 59, the guide 45 is opened at a side end orthogonal to the conveyance direction at the end portion on the downstream side in the conveyance direction. A discharge port 61 is formed. The downstream bottom 59 is inclined toward the discharge port 61 so as to be positioned on the lower side toward the discharge port 61, and the wrapping coins C that have come into contact with the end wall 60 and stopped are shown in FIG. It discharges | emits toward the accommodating part 46 shown. The guide 45 releases the coins fed out from the packaging unit 13 from the discharge port 61 in a time shorter than the time interval for feeding out the packaging coins C from the packaging unit 13.

  As shown in FIG. 3, the printing device 47 is guided by a guide 45, and a camera 65 (imaging means) that captures an image of the wrapping coin C that is moving down the upstream guide portion 50, and is guided by the guide 45 and upstream thereof. A printing apparatus main body 66 (non-contact printing means) that performs non-contact printing on the wrapping coin C that is falling and moving the side guide portion 50 is provided. The printer main body 66 is disposed downstream of the camera 65 in the transport direction.

  The printing apparatus main body 66 includes a rotation drive mechanism 73 having a rotation motor 70 (rotation drive means) and a support 72 connected to the rotation shaft 71, and a print head 74 rotatably supported by the support 72. And a tilt drive mechanism 75 (tilt drive means) for rotating the print head 74 with respect to the support 72.

  The rotation motor 70 of the rotation drive mechanism 73 is fixed to the machine body side of the wrapping coin handling machine 11, the rotation shaft 71 is directed to the upstream guide portion 50, and the rotation center axis of the rotation shaft 71 is set to the upstream bottom portion 54, The posture is arranged in a vertical plane while being orthogonal to 55 boundary lines O.

  The support body 72 is disposed between the rotary motor 70 and the upstream guide unit 50, and is fixed to the rotary shaft 71 of the rotary motor 70. Therefore, in other words, the rotary motor 70 rotates the support 72. The support 72 has a box shape that accommodates the print head 74. The print head 74 performs printing by spraying ink onto the wrapping coin C. The print head 74 is disposed on the support 72 so that the discharge portion 77 that discharges ink faces the upstream bottom portions 54 and 55 of the upstream guide portion 50, and the support 72 is provided on the rotation shaft 78 of the discharge portion 77. It is connected to be tiltable. In other words, the support 72 supports the print head 74 in a tiltable manner. The rotational axis 78 of the rotational shaft 78 is parallel to the boundary line O of the upstream bottom portions 54 and 55. The print head 74 is provided with an engagement shaft 79 in parallel with the rotation shaft 78 on the side opposite to the discharge portion 77. The rotation shaft 78 and the engagement shaft 79 are provided on the same side of the print head 74 on the downstream side in the transport direction. For example, the discharge unit 77 does not move with respect to the print head 74, and performs printing by simultaneously ejecting ink from appropriate ones of a large number of dot discharge ports arranged in a grid pattern.

  The tilt drive mechanism 75 is provided in the support 72, and includes a tilt motor 81 and an arm 83 that connects the rotation shaft 82 to the engagement shaft 79. The tilt motor 81 is disposed between the print head 74 in the support 72 and the rotary motor 70 and is fixed to the support 72. In the tilting motor 81, the rotation shaft 82 is disposed on the downstream side in the transport direction, and the rotation center axis thereof is parallel to the rotation center axis of the rotation shaft 78. One end side of the arm 83 is fixed to the rotation shaft 82 of the tilting motor 81, and the other end side is rotatably engaged with the engagement shaft 79.

  The tilt drive mechanism 75 swings the arm 83 when the tilt motor 81 rotates the rotary shaft 82, thereby tilting the print head 74 about the rotary shaft 78. The print head 74 tilts about the rotation center axis of the rotation shaft 78, and the rotation center axis is parallel to the boundary line O. For this reason, the print head 74 can be tilted in a plane orthogonal to the moving direction of the wrapping coin C guided by the guide 45 and moving the upstream guide portion 50.

  When the rotation motor 71 rotates the rotation motor 70, the support body 72 is rotated integrally with the rotation shaft 71. The rotation center axis of the rotation shaft 71 is orthogonal to the boundary line O. Therefore, the print head 74 is rotatable around an axis line disposed in a plane orthogonal to the moving direction of the wrapping coin C guided by the guide 45 and moving the upstream guide portion 50.

  As described above, the print head 74 is capable of changing the posture of the discharge unit 77 and the whole. Here, the state in which the ejection portion 77 of the print head 74 has the position in the guide width direction aligned with the boundary line O and the rotation shaft 78 of the print head 74 is in a posture along the boundary line O is the print head. 74, the tilt drive mechanism 75, the rotation drive mechanism 73, and the printing apparatus main body 66 are in a standby state.

  Next, the control contents of the control device 15 that controls the posture of the print head 74 based on the image data of the camera 65 and causes the printing device main body 66 to print on the wrapping coin C will be described.

  The camera 65 captures an image of the wrapping coin C fed out after wrapping from the wrapping unit 13 while the upstream guide unit 50 is falling. Here, as described above, as shown in FIG. 5 (a), the upstream guide portion 50 causes the cylindrical wrapping coin C to be brought into line contact with both the upstream bottom portions 54 and 55 by gravity, thereby causing the upstream guide portion 50 to move upstream. The position and posture are corrected so as to be closest to the boundary line O of the bottom portions 54 and 55 and to make the posture follow the extending direction of the boundary line O. Then, the upstream guide unit 50 guides the wrapping coin C so as to move in the extending direction of the boundary line O. The wrapping coin C in this state is set to a normal movement state.

  However, depending on the discharge posture and the discharge position from the packaging unit 13, the packaging coin C may not be completely corrected as described above. For example, as shown in FIG. 5B, the wrapping coin C is in line contact with only one upstream bottom 54 of the upstream bottoms 54 and 55, and is not in contact with the other upstream bottom 55. Although it follows the extending direction of the line O, the position in the guide width direction may be shifted to the upstream bottom 54 side. The packaging coin C in this state is set as a first abnormal movement state.

  Or, contrary to the above, as shown in FIG. 5 (c), the wrapping coin C is in line contact with only the other upstream bottom 55 of the upstream bottoms 54, 55, and one upstream bottom Although it does not contact 54 and extends along the extending direction of the boundary line O, the position in the guide width direction may be shifted to the other upstream bottom 55 side. Let the wrapping coin C of this state be a 2nd abnormal movement state.

  Alternatively, as shown in FIG. 6A, the wrapping coin C is in point contact with both the upstream bottom portions 54 and 55, and extends along the extending direction of the boundary line O of the one located at the center in the guide width direction. In some cases, the downstream side is inclined so that the downstream side is positioned closer to the upstream bottom 55 in the guide width direction than the upstream side. The wrapping coin C in this state is set as a third abnormal movement state.

  Or as shown in FIG.6 (b), the wrapping coin C will be in the point-contact state to both the upstream bottom parts 54 and 55, and it follows the extension direction of the boundary line O of what is located in the center of a guide width direction. In some cases, the downstream side is more inclined than the upstream side so as to be positioned on the upstream bottom 54 side in the guide width direction. Let the wrapping coin C of this state be a 4th abnormal movement state.

  Alternatively, as shown in FIG. 6C, the wrapping coin C is in line contact with one upstream bottom 54 of the upstream bottoms 54 and 55 and is in point contact with the other upstream bottom 55, or The upstream bottom portions 54 and 55 are in point contact with each other and are located closer to one upstream bottom portion 54 side than the center in the guide width direction, and the downstream side is not along the extending direction of the boundary line O. There is a case where it is inclined so as to be located closer to the upstream side bottom 55 in the guide width direction than the upstream side. Let the wrapping coin C of this state be a 5th abnormal movement state.

  Alternatively, as shown in FIG. 6 (d), the wrapping coin C is in a point contact with one upstream bottom 54 of the upstream bottoms 54, 55 and in line contact with the other upstream bottom 55, or The upstream side bottom portions 54 and 55 are in point contact with each other and are located closer to the other upstream side bottom portion 55 side than the center in the guide width direction, and the downstream side is not along the extending direction of the boundary line O. There is a case where it is inclined with respect to the upstream side so as to be positioned on the upstream side bottom 54 side in the guide width direction. Let the packaging coin C of this state be a 6th abnormal movement state.

  The wrapping coin C that moves the guide 45 includes an abnormal wrapping coin C that has an excess or shortage of coins and a normal wrapping coin C that has no excess or shortage of coins. The movement state is classified into seven types, a normal movement state and first to sixth abnormal movement states. The control device 15 moves the upstream guide unit 50 and determines whether the wrapping coin C imaged by the camera 65 is an abnormal or normal wrapping coin C from the wrapping unit 13 and the camera 65. It is grasped based on the time difference with the timing of imaging. Then, the control device 15 detects the drop speed, the drop posture, and the drop position during the drop movement of the upstream guide unit 50 based on the imaging data of the camera 65 for only the normal wrapping coin C. Then, the control device 15 performs printing by controlling the posture of the print head 74 of the printing device main body 66 and the timing of printing based on the detection result of the drop speed, the drop posture, and the drop position. On the other hand, for the abnormal wrapping coin C, the control device 15 does not perform printing by the printing device main body 66.

  Hereinafter, a printing process on a normal wrapping coin C will be described.

  For example, when the wrapping coin C moves in a normal movement state as shown in FIG. 5A, the control device 15 determines whether the wrapping coin C is based on the imaging data of the camera 65 that captured the wrapping coin C. Detecting the falling speed, detecting that the falling posture of the wrapping coin C is along the boundary line O, and further detecting that the falling position of the wrapping coin C coincides with the boundary line O in the guide width direction. become.

  Then, the control device 15 uses the discharge unit 77 at a central position in the length direction of the wrapping coin C, which is calculated from the falling speed of the wrapping coin C after the camera 65 captures an image while the printing device main body 66 is in a standby state. At a timing at which printing can be performed, ink is sprayed from the discharge portion 77 to the opposing packaging coin C to print predetermined printing information on the packaging coin C. Thereby, the printing information is printed in a state where the direction is aligned in the length direction of the wrapping coin C at the center position in the length direction of the wrapping coin C. For example, as shown in FIG. 7, the print information includes the date of printing (in the example shown, “20xxx / xxx / xxx”), and the wrapping coin C is identified from other wrapping coins. Is an identification number (“123456789” in the illustrated example). The denomination and total amount may be included in the print information.

  Further, for example, when the wrapping coin C moves in the first abnormal movement state as shown in FIG. 5B, the control device 15, based on the imaging data of the camera 65 that captured the wrapping coin C, While detecting the falling speed of the wrapping coin C, it is detected that the falling posture of the wrapping coin C is along the boundary line O, and further, the displacement direction of the wrapping coin C relative to the boundary line O in the guide width direction ( The direction of the upstream bottom 54) and the amount of deviation (distance) are detected.

  Then, the control device 15 drives the tilting drive mechanism 75 while the rotation drive mechanism 73 is in the standby state, and the discharge unit 77 is in the same direction as the direction of the wrapping coins C (the direction of the upstream bottom 54). The print head 74 is tilted so that the posture is changed by an amount corresponding to the amount of deviation of the wrapping coin C. In addition, after imaging by the camera 65, the ink is opposed from the ejection unit 77 at a timing at which printing can be performed by the ejection unit 77 at the center position in the length direction of the packaging coin C, which is calculated from the falling speed of the packaging coin C. The wrapping coin C is sprayed to print predetermined printing information on the wrapping coin C. Thereby, the printing information is printed in a state where the direction is aligned in the length direction of the wrapping coin C at the center position in the length direction of the wrapping coin C.

  Further, for example, when the wrapping coin C moves in the second abnormal movement state as shown in FIG. 5C, the control device 15, based on the imaging data of the camera 65 that captured the wrapping coin C, While detecting the falling speed of the wrapping coin C, it is detected that the falling posture of the wrapping coin C is along the boundary line O, and further, the displacement direction of the wrapping coin C relative to the boundary line O in the guide width direction ( The direction of the upstream bottom 55) and the amount of deviation (distance) are detected.

  Then, the control device 15 drives the tilting drive mechanism 75 while the rotation drive mechanism 73 is in the standby state, and the discharge unit 77 is in the same direction as the direction of the wrapping coins C (the direction of the upstream bottom 55). The print head 74 is tilted so that the posture is changed by an amount corresponding to the amount of deviation of the wrapping coin C. In addition, after imaging by the camera 65, the ink is opposed from the ejection unit 77 at a timing at which printing can be performed by the ejection unit 77 at the center position in the length direction of the packaging coin C, which is calculated from the falling speed of the packaging coin C. The wrapping coin C is sprayed to print predetermined printing information on the wrapping coin C. Thereby, the printing information is printed in a state where the direction is aligned in the length direction of the wrapping coin C at the center position in the length direction of the wrapping coin C.

  Further, for example, when the wrapping coin C moves in the third abnormal movement state as shown in FIG. 6A, the control device 15, based on the imaging data of the camera 65 that captured the wrapping coin C, While detecting the falling speed of the wrapping coin C, it is detected that the falling position of the wrapping coin C coincides with the boundary line O and the guide width direction, and further, the inclination direction of the falling posture of the wrapping coin C with respect to the boundary line O ( The direction closer to the upstream bottom 55) and the amount of inclination (angle) are detected on the downstream side.

  Then, the control device 15 drives the rotation drive mechanism 73 while the tilt drive mechanism 75 is in the standby state, and the discharge portion 77 is in the same direction as the tilt direction of the wrapping coin C (the upstream bottom portion 55 is closer to the downstream side). The print head 74 is rotated so that the posture is changed by an inclination amount corresponding to the inclination amount of the wrapping coin C. In addition, after imaging by the camera 65, the ink is opposed from the ejection unit 77 at a timing at which printing can be performed by the ejection unit 77 at the center position in the length direction of the packaging coin C, which is calculated from the falling speed of the packaging coin C. The wrapping coin C is sprayed to print predetermined printing information on the wrapping coin C. Thereby, the printing information is printed in a state where the direction is aligned in the length direction of the wrapping coin C at the center position in the length direction of the wrapping coin C.

  Further, for example, when the wrapping coin C moves in the fourth abnormal movement state as shown in FIG. 6B, the control device 15, based on the imaging data of the camera 65 that captured the wrapping coin C, While detecting the falling speed of the wrapping coin C, it is detected that the falling position of the wrapping coin C coincides with the boundary line O and the guide width direction, and further, the inclination direction of the falling posture of the wrapping coin C with respect to the boundary line O ( The direction closer to the upstream bottom 54 and the amount of inclination (angle) are detected on the downstream side.

  Then, the control device 15 drives the rotation drive mechanism 73 while the tilt drive mechanism 75 is in the standby state, and the discharge unit 77 is in the same direction as the tilt direction of the wrapping coin C (the upstream bottom 54 on the downstream side). The print head 74 is rotated so that the posture is changed by an inclination amount corresponding to the inclination amount of the wrapping coin C. In addition, after imaging by the camera 65, the ink is opposed from the ejection unit 77 at a timing at which printing can be performed by the ejection unit 77 at the center position in the length direction of the packaging coin C, which is calculated from the falling speed of the packaging coin C. The wrapping coin C is sprayed to print predetermined printing information on the wrapping coin C. Thereby, the printing information is printed in a state where the direction is aligned in the length direction of the wrapping coin C at the center position in the length direction of the wrapping coin C.

  Further, for example, when the wrapping coin C moves in the fifth abnormal movement state as shown in FIG. 6C, the control device 15, based on the imaging data of the camera 65 that captured the wrapping coin C, While detecting the falling speed of the wrapping coin C, the shift direction (the direction of the upstream bottom 54) and the shift amount (distance) with respect to the boundary line O of the drop position in the guide width direction of the wrapping coin C are detected. The direction of the inclination with respect to the boundary line O of the falling posture of the coin C (the direction closer to the upstream bottom 55 as the downstream side) and the amount of inclination (angle) are detected.

  Then, the control device 15 drives the tilt drive mechanism 75 so that the discharge unit 77 is in the same direction as the direction of the wrapping coin C shift (the direction of the upstream bottom 54) according to the amount of shift of the wrapping coin C. The print head 74 is tilted so as to change the posture only, and the rotation drive mechanism 73 is driven so that the discharge portion 77 is in the same direction as the inclination of the wrapping coin C (the direction closer to the upstream bottom 55 toward the downstream side). ), The print head 74 is rotated so that the posture is changed by an inclination amount corresponding to the inclination amount of the wrapping coin C. In addition, after imaging by the camera 65, the ink is opposed from the ejection unit 77 at a timing at which printing can be performed by the ejection unit 77 at the center position in the length direction of the packaging coin C, which is calculated from the falling speed of the packaging coin C. The wrapping coin C is sprayed to print predetermined printing information on the wrapping coin C. Thereby, the printing information is printed in a state where the direction is aligned in the length direction of the wrapping coin C at the center position in the length direction of the wrapping coin C.

  Further, for example, when the wrapping coin C moves in the sixth abnormal movement state as shown in FIG. 6D, the control device 15, based on the imaging data of the camera 65 that captured the wrapping coin C, While detecting the falling speed of the wrapping coin C, the shift direction (the direction of the upstream bottom 55) and the shift amount (distance) with respect to the boundary line O of the drop position in the guide width direction of the wrapping coin C are detected. The direction of the inclination with respect to the boundary line O of the falling posture of the coin C (the direction closer to the upstream bottom 54 as the downstream side) and the amount of inclination (angle) are detected.

  Then, the control device 15 drives the tilt drive mechanism 75 so that the discharge portion 77 is in the same direction as the displacement direction of the wrapping coin C (the direction of the upstream bottom 55) according to the displacement amount of the wrapping coin C. The print head 74 is tilted so as to change the posture only, and the rotation drive mechanism 73 is driven, so that the discharge portion 77 is in the same direction as the direction of inclination of the wrapping coin C (the direction closer to the upstream bottom 54 toward the downstream side). ), The print head 74 is rotated so that the posture is changed by an inclination amount corresponding to the inclination amount of the wrapping coin C. In addition, after imaging by the camera 65, the ink is opposed from the ejection unit 77 at a timing at which printing can be performed by the ejection unit 77 at the center position in the length direction of the packaging coin C, which is calculated from the falling speed of the packaging coin C. The wrapping coin C is sprayed to print predetermined printing information on the wrapping coin C. Thereby, the printing information is printed in a state where the direction is aligned in the length direction of the wrapping coin C at the center position in the length direction of the wrapping coin C.

  According to the wrapping coin handling machine 11 of the present embodiment described above, the control device 15 controls the posture of the print head 74 based on the imaging data of the wrapping coin C moving the guide 45 by the camera 65. Since printing is performed on the wrapping coin C by the printing apparatus main body 66 including the print head 74, printing can be performed in accordance with the posture of the wrapping coin C. Therefore, it can suppress that the printing on the packaging coin C becomes defective. In addition, since the printing is performed directly on the wrapping coin C, the number of times the printed wrapping paper S is wasted as in the case of printing on the wrapping paper S before wrapping can be reduced, and no specially processed expensive wrapping material is required. It becomes. Therefore, the wrapping paper S can be suppressed, and the operation cost can be reduced. In addition, since printing is performed on the wrapping coin C while the guide 45 is moving, it is possible to suppress an increase in transport time without reducing the transport speed of the wrapping coin C.

  Further, the guide 45 guides the wrapping coin C that is dropped and moved, and the camera 65 images the wrapping coin C that is guided by the guide 45 and is dropped and moved as described above. Then, printing is performed on the wrapping coin C which is guided by the guide 45 and is falling and moving. This eliminates the need for a special transport device and can reduce the cost.

  Further, the control device 15 detects the falling speed, the falling posture and the falling position of the wrapping coin C from the imaging data of the camera 65, and based on the detection result of the falling speed, the falling posture and the falling position, the posture of the print head 74 and Control the timing of printing. Therefore, it is possible to print well on the wrapping coins C that are conveyed by conveyance with unstable conveyance speed, conveyance posture, and conveyance position, in which the guide 45 guides the fall.

  Further, since the print head 74 performs printing by spraying ink on the wrapping coin C, the cost can be reduced. Further, suppression of waste of the printed packaging paper S also leads to suppression of waste of ink.

  Further, the print head 74 can be tilted in a plane orthogonal to the moving direction of the wrapping coin C that is guided and moved by the guide 45, and can rotate around an axis line disposed in the plane. The posture of the print head 74 can be made to correspond to the position and posture of the wrapping coin C with a relatively simple operation.

  The tilting drive mechanism 75 tilts the print head 74 with respect to the support 72 to change the printing direction. When the rotation motor 70 of the rotation drive mechanism 73 rotates the support 72, the print head 74 is moved. Rotate to change the print inclination. Therefore, the posture of the print head 74 can be made to correspond to the position and posture of the wrapping coin C with a relatively simple structure.

  In addition, when guiding the movement of the wrapping coin C fed from the wrapping portion 13 for producing the wrapping coin C with the guide 45, the wrapping portion 13 prints on the wrapping paper S before wrapping in order to directly print on the wrapping coin C. Thus, the number of times the printed wrapping paper S before packaging is wasted can be reduced.

  Further, since the control device 15 causes only the normal wrapping coins C to be printed by the printing device main body 66, normality and abnormality can be identified from the presence or absence of printing, and normality and abnormality can be easily identified. Further, the number of times the printed wrapping paper S after packaging is wasted can be reduced.
