On the other hand, the ink of each inking device 25 is transferred to the first ink collecting cylinder 23 via the chablon cylinder 24 and supplied onto the intaglio surface of the first printing cylinder 22, so that the excess ink is stored. The sheet 1 is removed by the first wiping roller 26, and the sheet 1 passes between the first impression cylinder 21 and the first plate cylinder 22. The above ink is transferred and intaglio printed. That.

  After the intaglio-printed sheet 1 is transferred to the transfer cylinder 34 via the transfer cylinders 31 to 33, the ink printed on the one side is dried by the dryer 61. , The suction drum 41 of the reversing unit 40, the reversing drum 42, and the transfer drum 35 are transferred to the second twist adjusting drum 300, and the second top and bottom adjusting drum 400 is used to transfer the second While being held by the second impression cylinder 51 of the intaglio printing unit 50 so that one surface is directed outward, the ink of each inking device 55 passes through the chablon cylinder 54 and the second ink set. The ink is transferred to the cylinder 53 and supplied onto the intaglio surface of the second plate cylinder 52, the excess ink is removed by the second wiping roller 56, and the sheet 1 is moved to the second pressure. Body 51 and the second edition By passing between the 52, further the ink on one side of the leaf paper 1 is subjected to further intaglio printing is transferred.

  In this way, the sheet 1 that has been further subjected to intaglio printing on one side by the second intaglio printing unit 50 is transferred to the discharge chain 72 via the discharge cylinder 71 of the discharge device 70. The paper is transported while being held by the hooks, and is discharged and stacked on the discharge trays 73A to 73C.

  On the other hand, for example, when performing intaglio printing on one side and the other side of the sheet 1, first, the one side and the other side of the sheet 1 from the transfer cylinder 34 are reversed to The reversing unit 40 is set so as to be transferred to the transfer drum 35.

  Subsequently, as in the case described above, the clutch 556 is turned “ON” so as to connect the gear train 541 and the gear train 545, and the drive motors 542, 548, etc. are operated. Then, a signal is input to the input device 601 to start a printing operation.

  Thus, the sheets 1 on the paper feed tray 11 of the paper feeder 10 are fed one by one onto the feeder board 12 as described above, and the swing device 13 It is transferred to the first twist adjusting cylinder 100 and is transferred to the first impression cylinder 21 of the first intaglio printing unit 20 via the first top and bottom adjusting cylinder 200, with one surface facing outward. In this way, the ink is transferred and intaglio-printed on one side by passing between the first impression cylinder 21 and the first plate cylinder 22, and then transferring the ink. The ink transferred to the transfer cylinder 34 via the cylinders 31 to 33 and printed on one surface is dried by the dryer 61.

  Then, the sheet 1 dried with the ink printed on one side is reversed by the suction cylinder 41 and the reversing cylinder 42 of the reversing unit 40 (specific operation is described in, for example, the above-mentioned patent document). 2), the second pressure is applied to the second twist adjustment cylinder 300 via the transfer cylinder 35, and the second pressure of the second intaglio printing unit 50 via the second top adjustment cylinder 400. The ink is transferred to the other surface by being transported while being held by the cylinder 51 with the other surface facing outward, and passing between the second impression cylinder 51 and the second plate cylinder 52. Intaglio printed.

  In this way, the sheet 1 that has been further intaglio printed on the other surface by the second intaglio printing unit 50 is the discharge cylinder 71 of the discharge device 70 as described above. The paper is held by the hooks of the paper discharge chain 72 and conveyed, and is discharged and stacked on the paper discharge trays 73A to 73C.

  In this way, the operator visually confirms the printing state of the sheet 1 that has been subjected to intaglio printing by the intaglio printing units 20 and 50 and discharged onto the paper discharge trays 73A to 73C of the paper discharge device 70. For example, when the pattern printed by the first intaglio printing unit 20 has a deviation in the twist direction, a twist adjustment amount (for example, +1 mm) for correcting the deviation is input to the input device 601. To enter.

  The control device 600 controls the operation of the first twist adjustment motor 137 of the first twist adjustment cylinder 100 so as to correspond to the input twist adjustment amount based on a command from the input device 601. By swinging the lever 139 via the top 141, the rod 142 pivotally attached to the free end of the lever 139 is advanced and retracted, and the eccentric bearing 136 pivotally attached to the tip thereof is desired. And the shaft center position on one end side of the body main body 124 is moved from the shaft center A to the shaft center B by the eccentric action of the eccentric bearing 136, so that the shaft center of the body main body 124 is inclined. Then, the first intaglio printing unit 20 adjusts the shift of the position of the pattern printed on the sheet 1 by twisting.

  Further, for example, when the pattern of the sheet 1 printed on the intaglio printing by the first intaglio printing unit 20 is shifted in the vertical direction, the vertical adjustment amount for correcting the shift (for example, −1 mm or the like) ) Is input to the input device 601.

  The control device 600 moves the helical gear 200b in the axial direction by the axial movement amount of the helical gear 200b corresponding to the input vertical adjustment amount based on the command from the input device 601. The first top and bottom adjustment motor 291 is controlled to move, and the helical gear 200b is moved relative to the helical gear 21a of the first impression cylinder 21 in the axial direction. By changing the meshing position of the helical gear 21a with respect to the helical gear 200b, the first impression cylinder with respect to the rotational phase in the circumferential direction (vertical direction) of the trunk main body 201 of the first vertical adjustment cylinder 200. 21 is changed, that is, the relative rotational phase of the cylinder body 201 and the first impression cylinder 21 in the circumferential direction (vertical direction) is adjusted.

  As a result, the first impression cylinder 21 replaces the sheet 1 from the gripper device of the first top adjustment cylinder 200 to the gripper device at the timing of the rotational phase that becomes the top and bottom adjustment amount. To receive. For this reason, the sheet 1 is held in the holding claw device of the first impression cylinder 21 while being shifted by the top and bottom adjustment amount, and intaglio printing is performed on the first plate cylinder 22. Therefore, the above-described shift in the position of the pattern printed by the first intaglio printing unit 20 is adjusted upside down.

  On the other hand, for example, when the pattern of the sheet 1 printed on the intaglio printing by the second intaglio printing unit 50 has a deviation in the twist direction, a twist adjustment amount (for example, +2 mm or the like) for correcting the deviation. Is input to the input device 601, the control device 600, based on a command from the input device 601, the second twist adjustment cylinder 300 of the second twist adjustment cylinder 300 so as to correspond to the input twist adjustment amount. By controlling the operation of the twist adjustment motor 337, as in the case of the first twist adjustment cylinder 100, in the second twist adjustment cylinder 300, the axis is inclined to adjust the shift.

  For example, when the pattern of the sheet 1 printed on the intaglio printing by the second intaglio printing unit 50 has a deviation in the vertical direction, the vertical adjustment amount (for example, -2 mm or the like) for correcting the deviation. ) Is input to the input device 601, the control device 600, based on the command from the input device 601, the second top and bottom adjustment cylinder 400 of the second top and bottom adjustment cylinder 400 so as to correspond to the input top and bottom adjustment amount. In the same way as in the case of the first top and bottom adjustment cylinder 200, the rotation adjustment of the second top and bottom adjustment cylinder 400 is performed to adjust the above-mentioned shift.

  In this way, by adjusting the deviation by the adjusting cylinders 100, 200, 300, 400, intaglio printing is performed on the sheet 1 by the first intaglio printing unit 20 and the second intaglio printing unit 50. The position of the pattern can be made as specified.

  In addition, after the above-described printing operation is completed, the intaglio of the plate cylinders 22 and 52 of the intaglio printing units 20 and 50 is replaced, the ink collecting cylinders 23 and 53, the chablon cylinders 24 and 54, etc. are washed. When performing the print preparation work, maintenance inspection work, etc., first, when the input device 601 is operated to disconnect the gear train 541 and the gear train 545, the control device 600 The operation of the clutch 556 is controlled so that the clutch 556 is turned off.

  When the input device 601 is operated so as to operate the first drive motor 542, the control device 600 operates the first drive motor 542. Accordingly, the first drive motor 542 transmits the driving force only to the gear train 541 without transmitting the driving force to the gear train 545, and does not operate the second intaglio printing unit 50. Only the intaglio printing unit 20 is operated.

  On the other hand, when the input device 601 is operated to operate the second drive motor 548, the control device 600 operates the second drive motor 548. As a result, the second drive motor 548 transmits the driving force only to the gear train 545 without transmitting to the gear train 541, and does not operate the first intaglio printing unit 20. Only the intaglio printing unit 50 is operated.

  Here, the first twist adjustment cylinder 100, the first top and bottom adjustment cylinder 200, and the first intaglio printing unit 20 that are rotated by the driving force of the first drive motor 542 via the gear train 541. The first impression cylinder 21, the first plate cylinder 22, the first ink collecting cylinder 23, the chablon cylinder 24, the transfer cylinders 31 to 34, the suction cylinder 41 of the reversing unit 40, the reversal The cylinder 42, the transfer cylinder 35, the second twist adjustment cylinder 300, the second top and bottom adjustment cylinder 300 rotated by the driving force of the second drive motor 548 through the gear train 545, the first The second impression cylinder 51, the second plate cylinder 52, the second ink collecting cylinder 53, the chablon cylinder 54, and the paper discharge cylinder 71 of the second intaglio printing unit 50 have different rotational phases. Although it becomes Since the second twist adjustment cylinder 300 and the second top and bottom adjustment cylinder 400 each have the claw relief mechanism as described above, it is possible to avoid mutual interference (contact etc.). it can.

  As a result, the clutch 556 is turned off, whereby the first intaglio printing unit 20 and the second intaglio printing unit 50 are moved to the first drive motor 542 and the second drive motor 548. Can be operated independently of each other.

  For this reason, the printing preparation work and maintenance inspection of the first intaglio printing unit 20 and the printing preparation work and maintenance inspection work of the second intaglio printing unit 50 are independently and simultaneously performed in parallel. be able to.

  Therefore, according to the intaglio printing press according to the present embodiment, the following effects can be obtained.
