Is adsorbed to one weir plate adsorption part (55) of the original roller (3) and the ink fountain forming surface (37a) corresponding to this, and then another damp plate (53) is similarly attached to the original roller (53 It is adsorbed to the other weir plate adsorbing part (55) of 3) and the ink fountain forming surface (37a) corresponding thereto.
- the ink supply device (86) moves away from the container holding device (77) and moves above the ink fountain (1). Then, while only the original roller (3) is rotated and all the ink transfer rollers (15) are switched to the rear end position, the ink replenishing device (86) is moved back and forth back and forth while moving the ink fountain to a certain level. Supply ink in (1). At this time, the ink level in the ink fountain (1) is lowered so that a small amount of ink is collected only in a small part near the ink passage (52).
- the kneading roller (4) and other rollers are also rotated to control the switching of the position of the ink transfer roller (15). Ink is supplied to the printing surface and printing is performed.
- the ink supply device (86) is moved left and right while ink is supplied into the ink fountain (1), thereby keeping the ink level in the ink fountain (1) almost constant. Thus, a small amount of ink should be collected only in a small part near the ink passage (52).
- an abnormality in the switching of the position of the ink transfer roller (15) is detected by the output of the position switching detection sensor (102), an alarm is issued and the operation is stopped.
- the setup change operation is performed as follows, for example.
- the ink supply device (86) moves to the front of the original container holding device (77) of the container storage section (66), and then moves to the rear, and the container holding device. Return the ink container (65) to (77).
- the ink supply device (86) stops at a position where the held container (65) is located directly above the bottom receiving portion (78) of the original container holding device (77).
- Figure 8 (a) shows such a situation.
- the container holding device (77) is stopped at the lower end position.
- the ink supply device (86) is stopped, the container holding device (77) is raised to the upper end position.
- the container (65) is lifted by the bottom receiving portion (78) of the container holding device (77), so that the pair of ink holding members (93) is opened and the ink holding member (93) is opened.
- the replenishing device (86) moves forward and leaves the container holding device (77).
- the ink fountain forming surface adsorption part (53a) of the dam plate (53) is disengaged from the ink fountain forming surface (37a), and the dam plate (53) It rotates counterclockwise with the original roller (3) while adsorbed to the original roller (3), but immediately hits the cover (110) and is stopped. Further, when the ink fountain member (2) further rotates, the barrier plate (53) rotates around the contact portion with the cover (110), and the ink original roller adsorbing portion (53b) becomes the original roller. Outer surface of (3) The ink fountain member (2) stops with the weir plate (53) resting on and resting on both the ink fountain member (2) and the original roller (3).
- the dam plate holding member (91) of the dam plate changer (85) holds the dam plate (53) in the opposite direction, and the ink fountain member (2) and the original roller ( After removing from 3) and moving to the second mounting table (61), similarly remove the other weir plate (53) and transfer to the second mounting table (61).
- the ink transferred to the ink transfer roller (15) is transferred to the kneading roller (4) and other rollers by the rotation of the kneading roller (4), and these rollers (15) (4) Less ink remains on the outer surface.
- the ink transfer roller (15), the kneading roller (4) and other rollers are automatically cleaned as before.
- the cleaning liquid for automatic cleaning is transferred from the kneading roller (4) side to the original roller (4). It is possible to move to 3) and clean the outer surface of the original roller (3) automatically.
- the sheet moving device (40) removes the predetermined length from the sheet roll (49).
- the sheet (39) is fed out and scraped off to the scraping member (50).
- the ink fountain member (2) is positioned at the working position for the next printing and stopped.
- the partial force of the used sheet (39) that adheres to the ink fountain forming surface (37a) and has old ink adhered during printing moves to a position off the S ink fountain forming surface (37).
- the partial force of the new sheet (39) before use is in close contact with the S ink fountain forming surface (37).
- FIG. 12 shows a modified example of the ink fountain member.
- the ink fountain member (104) has, for example, a quadrangular prism shape with a square cross section and is 90 degrees apart. It is positioned at the four working positions and fixed at each working position.
- the four sides around the ink fountain member (104) are the ink fountain forming surfaces (105a) (105b) (105c) (105d), and each ink forming surface (105a) to (105d) is counterclockwise.
- the ridge line at the end of the ink becomes the ink passage forming portions (106a) (106b) (106c) (106d) corresponding to the ink forming surfaces (105a) to (105d).
- FIG. 13 shows another modification of the ink fountain member.
- the ink fountain member (107) has, for example, a triangular prism shape with a right-angled cross section, and is positioned and fixed only at one working position.
- the rear surface of the ink fountain member (107) is the ink fountain forming surface (108), and the ridge line force at the rear end (lower end) of the ink fountain forming surface (108) It has become.
- the ink fountain member (107) is rotated counterclockwise from the working position, and is returned to the working position after the barrier plate (53) is removed as described above. It has become like that.
- the overall configuration of the ink supply device of the printing press and the configuration of each unit are not limited to those of the above-described embodiment, and can be changed as appropriate.
- the present invention is suitable for use in an ink transfer division roller unit and a printing machine.
- the ink transfer dividing roller unit and the printing machine according to the present invention it is possible to detect an abnormality in switching the position of the ink transfer roller and to prevent the occurrence of the abnormality.
