Abstract

PROBLEM TO BE SOLVED: To provide a device for adjusting the contact pressure of an intaglio printing press capable of reducing a load on an operator in print preparation, and eliminating the waste of print materials such as paper and ink.SOLUTION: The contact pressure of a wiping roll 20 after it is adjusted in accordance with printing specifications such as a type of ink and a type of a pattern is stored, and when printing is performed in accordance with the same print specifications again, the stored contact pressure of the wiping roll 20 is read and set.

Description

  The present invention relates to a contact pressure adjusting method and a contact pressure adjusting device for an intaglio printing press.

  The wiping device of an intaglio printing machine presses a wiping roll against the intaglio plate mounted on the intaglio cylinder to generate a nip, and rotates in the opposite direction to the intaglio cylinder to scrape off excess ink in the non-image area on the intaglio plate. However, every time a new printing specification (job) such as ink type or pattern type is started, the operator visually confirms the intaglio and adjusts the contact pressure of the wiping roll. The first problem is that printing materials such as paper and ink are wasted.

  In addition, since the surface of the wiping roll of the wiping device is made of resin or rubber, the contact pressure against the intaglio cylinder changes due to wear due to use or expansion due to heat during use. .

  Therefore, conventionally, as disclosed in Patent Document 1, the wiping roll is independently driven by a dedicated motor, and a magnetostriction sensor (torque sensor) is interposed in the rotation drive system via a coupling. By controlling the contact pressure adjustment motor that adjusts the contact pressure of the wiping roll to the intaglio cylinder according to the output of the magnetostrictive sensor, the contact pressure of the wiping roll to the intaglio cylinder is controlled to be always constant. It was.

  However, since the magnetostrictive sensor detects the mechanical distortion of the rotational drive system, the notch portion of each cylinder from the state where the intaglio cylinder surface and the impression cylinder surface are in contact with each other and printing pressure is applied during printing. Is also affected by mechanical vibration when switching to a state where no printing pressure is applied oppositely, and vice versa, that is, noise and other disturbances are also detected. There was a second problem that it was impossible to stably detect changes over time.

  Since the magnetostrictive sensor is provided between the speed reducer connected to the wiping / roll single drive motor and the drive shaft of the wiping / roll, the mechanical vibration affects the second, and the second The problem becomes bigger.

As a result, the burden on the operator for preparing for printing is reduced, and waste of printing materials such as paper and ink can be eliminated.

  Further, the contact pressure (load) of the wiping roll 20 with respect to the intaglio cylinder 17 is converted into the torque value (current value) of the wiping roll drive motor 40 and this is fed back to the wiping roll contact pressure adjusting motor 30. Therefore, the contact pressure can be adjusted automatically and always with high accuracy without being affected by mechanical vibration (disturbance such as noise).

  Further, in this embodiment, since a reduction gear 46 comprising a worm gear mechanism is interposed in the drive system between the wiping / roll driving motor 40 and the wiping / roll 20, mechanical vibration (load fluctuation) is caused by backlash in the reduction gear 46. In particular, since the worm gear mechanism is difficult to transmit mechanical vibration (load fluctuation) from the wiping roll 20 side to the wiping roll drive motor 40 side, the worm gear mechanism is more stable and has a long-term load. There is an advantage that only fluctuations can be detected effectively.

  With the above operation flow, when the intaglio printing press is in steady operation, the wiping roll contact pressure is adjusted so that the wiping roll 20 is always applied to the intaglio cylinder 17 with the optimum contact pressure according to the type of ink and the type of pattern. The motor 30 is driven and controlled.

  As described above, in this embodiment, when the same ink type and pattern type are printed again, the contact pressure of the wiping roll 20 stored in advance corresponding thereto is read and set. As a result, the burden on the operator for preparing for printing is reduced, and waste of printing materials such as paper and ink can be eliminated.

  Further, the contact pressure (load) of the wiping roll 20 with respect to the intaglio cylinder 17 is converted into a torque value (current value) of the wiping roll drive motor 40, and when this torque value exceeds a preset allowable value, wiping is performed. Since the roll contact pressure adjusting motor 30 is driven by a certain amount, the contact pressure can always be adjusted with high accuracy without being affected by mechanical vibration (disturbance such as noise).

  Further, in this embodiment, since a reduction gear 46 comprising a worm gear mechanism is interposed in the drive system between the wiping / roll driving motor 40 and the wiping / roll 20, mechanical vibration (load fluctuation) is caused by backlash in the reduction gear 46. In particular, since the worm gear mechanism is difficult to transmit mechanical vibration (load fluctuation) from the wiping roll 20 side to the wiping roll drive motor 40 side, the worm gear mechanism is more stable and has a long-term load. There is an advantage that only fluctuations can be detected effectively.

  Needless to say, the present invention is not limited to the above embodiments, and various modifications can be made without departing from the scope of the present invention.

  The present invention is applicable to a contact pressure adjusting method and a contact pressure adjusting device for an intaglio printing machine such as an intaglio printing machine.
