In the above-mentioned device, the deficiencies of the conventional swing method and roller-based tucking method are overcome, and the opening of the impression cylinder is located on the paper-holding side, and is elastically biased by a spring to move toward the paper-holding side. The front plate, which is supported in a horizontal manner, is configured to be able to move vertically and adjust tilting by horizontally moving slide plates with operating surfaces arranged on the operation side and the non-operation side by rotation of an eccentric slide pin. This is the earlier application proposed by the applicant.

The device configured as described above is effective in that it has a simple structure and can easily and accurately perform vertical parallel fine movement and oblique image adjustment. Setting of the state in which the opening edge of the impression cylinder is parallel to the opening edge of the impression cylinder is performed by turning the eccentric slide pin, but due to the accumulation of errors in each component, the eccentric slide pin is The eccentric center position is deviated from the center position, and therefore, the amount of movement of the front cover from the reference position is uneven in the vertical direction, and the amount of oblique image adjustment is limited.

In other words, according to the above-mentioned device, the front stopper is tilted through the slide plate by the eccentric slide pin, but the total tilt amount is determined by the eccentricity of the eccentric slide pin and the inclination angle of the operating surface on the slide plate. Therefore, in order to effectively use the oblique movement and ensure the maximum amount of oblique image adjustment, the front cover must be at the reference position at the eccentric center position of the eccentric slide pin. . The present invention is an improvement on the device of the above-mentioned earlier application, focusing on the fact that by doing so, the front support can be moved equally back and forth with respect to the reference position.

That is, the present invention facilitates the setting of the reference position of the front piece, and with the eccentric slide pin set at the eccentric center position, the front piece is moved in the left and right direction by rotation of the eccentric fulcrum pin, and the front piece is slid. By changing the relative position of the front pad to the plate and adjusting the vertical position of the front pad to obtain a parallel position, the eccentric amount of the eccentric slide pin can be used as the maximum amount of adjustment. The present invention provides an impression cylinder front register and oblique image fine adjustment device which is capable of immediately estimating the front cover movement amount from the eccentric position of the eccentric slide pin, and improves operability.

To explain the actual printing state in detail in this state, first, the first color is printed, then the printing paper is loaded on the paper feed table, the plate is replaced with the second color, and several sheets are printed. At this time, if both the lateral and front registers are good, you can continue printing as is, but the more printing accuracy is required, the more registration from the second color is necessary, so parallel fine movement and diagonal fine movement are necessary. Adjustments will be required.

Assuming that the entire printing paper 11 is parallel and shifted in the direction in which you want it to move forward, the adjustment at this time is to rotate one eccentric slide pin 13 clockwise and the other eccentric slide pin 13' counterclockwise by the same amount. When rotated, the slide plates 24 and 24' slide inward, so that the front cover 16 slightly moves toward the paper-holding end D side of the impression cylinder.

次に画像を斜めに調整する場合について述べ

When you want to adjust the operating side A of the printing paper 11 to advance and the counter-operating side B to retard, rotate one eccentric slide pin 13' to the left, and rotate the other eccentric slide pin 13 to the left to move the front stopper 16. becomes oblique. Therefore, oblique images of printed images are possible.

As explained above, according to the impression cylinder front register and oblique image fine adjustment device in an offset printing press according to the present invention, the impression cylinder 1 can be operated by arbitrarily rotating the eccentric slide pins 13 and 13' in the left and right directions. By sliding the slide plates 24, 24' provided on the side A and the non-operating side B, the front cover 16 is moved to the paper holding side of the impression cylinder 1 using its inclined operating surfaces 24a, 24'a. In this device, the front plate 16 is moved along the axis of the impression cylinder 1 by rotation of the eccentric fulcrum pin 30, and is configured to perform vertical parallel fine movement and oblique image adjustment by arbitrarily finely moving the paper in the direction A and the bottom side B of holding the paper in its mouth and diagonally. The eccentric slide pin 13 , 13' are set at the eccentric center position, the eccentric fulcrum pin 30 can be rotated to change the relative position of the front plate 16 with respect to the slide plates 24, 24' to obtain a parallel position. The reference position of the front plate 16 for holding the paper 11 parallel to the impression cylinder 1 can be easily set, and the eccentricity of the eccentric slide pins 13, 13' can be adjusted to the maximum. Since the amount of movement of the front stopper 16 can be estimated immediately from the eccentric position of the eccentric slide pins 13, 13', the adjustment device is easy to assemble and has excellent adjustment and operability. It has a positive effect.
