Description

The present invention relates to an intaglio printing press for performing intaglio printing on the sheet.

  For example, when intaglio printing is performed with an intaglio printing machine on a sheet of paper that has been offset printed with an offset printing machine, the intaglio printing is aligned (registered) with the offset printing printed on the sheet of paper. Thus, it is necessary to perform intaglio printing on the sheet with an intaglio printing machine.

  With respect to such registration, for example, in Patent Document 1 below, one shaft end of a transfer cylinder that delivers a sheet to the impression cylinder is supported by an eccentric bearing, and the axis of the transfer cylinder is attached to the impression cylinder. By allowing the sheet to be transferred from the transfer cylinder to the impression cylinder by allowing the sheet to be inclined with respect to the axis, the sheet printing can be adjusted in the twist direction with respect to the sheet. A twist adjustment device for the machine is proposed.

  As shown in FIG. 9, the potentiometers 122 and 223 are electrically connected to an input unit of a control device 300 as control means. The output unit of the control device 300 is electrically connected to the motors 116 and 213. A twist adjustment amount input device 301 for inputting an adjustment amount in the twist direction (see FIG. 10A) for the sheet 1 and an adjustment amount in the vertical direction for the sheet 1 (see FIG. 10B) are input to the input unit of the control device 300. ) Is input to the top and bottom adjustment amount input device 302, and the control device 300 is based on the information from the input devices 301 and 302 and the potentiometers 122 and 223. The operation of 213 can be controlled (details will be described later).

  Next, the operation of the intaglio printing press according to this embodiment will be described.

  When the sheet 1 previously offset printed by an offset printing machine or the like is set in the paper feeder 10 and the sheets 1 are fed one by one onto the feeder board 11, the sheet 1 is swung. The device 12 is held by the gripper device of the barrel main body 101 of the twist adjustment barrel 100 and is conveyed while being held on the outer peripheral surface of the barrel main body 101, and the gripper device of the barrel main body 201 of the top and bottom adjustment barrel 200. After being transferred and transported while being held on the outer peripheral surface of the cylinder body 201, it is transferred to the holding claw device of the impression cylinder 21 and held on the outer peripheral surface of the impression cylinder 21. 25 ink is transferred to the ink collecting cylinder 23 via the chablon cylinder 24 and supplied onto the intaglio surface of the plate cylinder 22, and the excess ink is removed by the wiping roller 26. When the sheet 1 passes between the impression cylinder 21 and the plate cylinder 22, the ink is further transferred onto the sheet 1 on which offset printing is performed, and intaglio printing is performed. Is conveyed by the paper discharge chain 32 of the paper discharge device 30 through the paper discharge drum 31 and discharged onto the paper discharge tray 33.

  When the operator visually confirms the sheet 1 on which the intaglio printing is applied to the offset printing in this way, for example, when the intaglio printing is displaced in the twist direction with respect to the offset printing (see FIG. 10A). ), When a twist adjustment amount (for example, +1 mm or the like) for correcting the deviation is input to the twist adjustment amount input device 301, the control device 300 is input based on information from the twist adjustment potentiometer 122. The operation of the twist adjustment motor 116 is controlled so that the eccentric bearing 102 is rotated as described above by the rotation amount of the eccentric bearing 102 corresponding to the twist adjustment amount.

  As a result, the twist adjusting cylinder 100 is oriented so that the cylinder body 101 tilts the axis of the cylinder main body 101 with respect to the axis of the impression cylinder 21, so that the twist is applied to the sheet 1 from the swing device 12. It is received by the holding claw device with an adjustment amount twisted and delivered to the holding claw device of the top and bottom adjustment barrel 200.

  For this reason, the sheet 1 is subjected to intaglio printing by the plate cylinder 22 while being held in a state in which the twist adjustment amount is applied to the gripping claw device of the impression cylinder 21, so that offset printing is performed. The deviation in the twist direction of the intaglio printing with respect to is corrected.

  Further, for example, when the intaglio printing has a deviation in the vertical direction with respect to the offset printing (see FIG. 10B), the vertical adjustment amount input device 302 supplies the vertical adjustment amount (for example, −1 mm) for correcting the deviation. Then, the control device 300 uses the amount of movement in the axial direction of the first helical gear 217 corresponding to the input vertical adjustment amount based on the information from the vertical adjustment potentiometer 223. The operation of the top / bottom adjustment motor 213 is controlled so that one helical gear 217 is moved in the axial direction as described above.

  As a result, the meshing position of the first helical gear 217 with respect to the second helical gear 21 a of the impression cylinder 21 changes, and the trunk main body of the top and bottom adjustment cylinder 200 with respect to the rotational phase of the impression cylinder 21. Since the rotation phase of 201 can be changed so as to be slowed down, the top / bottom adjustment cylinder 200 uses the twist adjustment cylinder 100 to replace the gripper device and receives the sheet 1 received as the top / bottom adjustment amount. It is delivered to the gripper device of the impression cylinder 21 at the timing of the rotation phase.

  Therefore, the intaglio printing is performed on the plate cylinder 22 while the sheet 1 is held in the gripper nail device of the impression cylinder 21 while being shifted by the top and bottom adjustment amount. Deviations in the vertical direction of printing are corrected.

  Therefore, according to the intaglio printing press according to this embodiment, it is possible to easily correct the deviation in the twist direction and the top-down direction with respect to the sheet 1 during intaglio printing.
