いる。 Traditionally, ink roller cleaning in offset printing presses involves rotating a series of rollers in the inking unit while disconnected from the printing plate and pot rollers.
In this state, spray the cleaning liquid from the nozzle onto the first oscillating roller and the rolling-in side of the kneading roller, and wash each roller surface with the cleaning liquid. This is done by collecting ink and cleaning fluid that have fallen off. Further, a large number of nozzles are arranged along the axial direction of the roller, so that the cleaning liquid is supplied over the entire length of the roller.
［発明が解決しようとする問題点］
この洗浄作業において、供給する洗浄液が多す
ぎると、回転駆動される最初の揺動ローラとつれ
回転する練りローラとの間でスリツプが発生し、
効果的な洗浄が行なえなくなる。そこで、従来は
洗浄液の供給量を少なくして洗浄を行つている。[Problems to be Solved by the Invention] In this cleaning operation, if too much cleaning liquid is supplied, slips will occur between the first swinging roller that is rotationally driven and the kneading roller that rotates with it.
Effective cleaning becomes impossible. Therefore, conventionally, cleaning is performed by reducing the amount of cleaning liquid supplied.
しかし、洗浄液の供給量が少ないと、洗浄効果
が低いことから洗浄に時間が掛る。また、洗浄液
を少なくしたからと言つて必ずしもスリツプの発
生を完全に防止できるものではなく、洗浄の信頼
度も低い。すなわち、印刷機のインキングローラ
のうち、着ローラや練りローラ等は駆動されずに
摩擦力により連れ回りしており、適量のインキが
ローラに着く程度の微妙なタツチ圧としてあるた
め、急に大量の洗浄液がこれらローラに供給され
ると、この液が潤滑剤的な役目になつて摩擦力が
低下してローラスリツプ現象を起こす。 However, if the amount of cleaning liquid supplied is small, the cleaning effect is low and cleaning takes time. Further, even if the amount of cleaning liquid is reduced, it is not necessarily possible to completely prevent the occurrence of slips, and the reliability of cleaning is also low. In other words, among the inking rollers of a printing press, the forming roller, kneading roller, etc. are not driven but are rotated together by frictional force, and there is a slight touch pressure that allows the appropriate amount of ink to land on the rollers, so suddenly When a large amount of cleaning liquid is supplied to these rollers, this liquid acts as a lubricant, reducing the frictional force and causing a roller slip phenomenon.
一方、洗浄液の供給量が一定量以下になると、
ドクターブレードとドクターブレードを当接させ
たローラとの間の摩擦が大きくなりすぎて、ドク
ターブレードおよびローラを損傷させるおそれも
ある。 On the other hand, when the supply amount of cleaning liquid becomes less than a certain amount,
There is also a possibility that the friction between the doctor blade and the roller with which the doctor blade is in contact becomes too large, causing damage to the doctor blade and the roller.

配設されている。[Means for Solving the Problems] The present invention solves the above-mentioned problems, provides a cleaning device with high cleaning efficiency for ink rollers, and prevents damage to the doctor blade and the rollers that come into contact with it. Ink roller cleaning, which involves spraying cleaning liquid from a nozzle onto the rollers near the pot roller of an inking device that has a series of roller groups that receive ink from the pot roller and supplying ink to the plate surface to remove ink that adheres to each roller. The nozzle is arranged so as to be able to reciprocate along the axial direction of the roller, and is equipped with a solenoid valve that can be switched to intermittently inject cleaning liquid during movement, and
The doctor blade is arranged so as to be able to approach and separate from the corresponding roller.
［作用］

とはない。[Function] The present invention provides an ink roller cleaning device for an inking device configured as described above, so that a single reciprocating nozzle is used to spray a plurality of ink rollers along the axial direction of the roller onto at least one roller close to the pot roller. This means that a large amount of cleaning liquid is sprayed locally, making the cleaning efficiency much higher than before, and there are also areas between each roller where there is less cleaning liquid, which causes rotational friction. The force is greater and there is no slippage like in the past.

浄液が達した後に、該ローラの周面にドクターブ
レードが接触するようにしているので、接触時に

濡れた状態にあり、両者の間の摩擦が大きくなり
すぎることはない。 In addition, after the cleaning liquid reaches the roller that the doctor blade contacts, the doctor blade comes into contact with the peripheral surface of the roller, so the area between the doctor blade and the roller is always sufficiently wet when they make contact. , the friction between the two will not become too large.

A nozzle 20 for spraying 9 is provided. Although the cleaning liquid 19 does not necessarily need to be sprayed at the rolled-up portion, it is most effective in this area since the cleaning liquid is diffused to a large extent. As shown in FIG. 2, the nozzle 20 is installed in a movable part 23 that is screwed onto a guide rod 22 having a male thread 21 disposed along the axial direction of the kneading roller 11, and is connected to a movable part 23 through a flexible tube 24. and is connected to the solenoid valve 25. Since the electromagnetic valve 25 supplies the cleaning liquid 19 during the ON operation, the cleaning liquid 19 is injected from the nozzle 20 for this ON operation time (T 1 ). The cleaning liquid supply time (T 1 ) from the nozzle 20 can be adjusted, and the cleaning liquid 1 is intermittently supplied, for example, every T 2 hours.

いる。 Further, a container 27 having a doctor blade 26 is provided as a recovery device for waste liquid (mixed liquid consisting of ink and cleaning liquid) in the cleaning device. This container 27 is moved backward (separated) during printing, but moves forward during the cleaning operation, bringing the doctor blade 26 at the tip into contact with the circumferential surface of the swinging roller 14 that contacts the ink forming roller 16, and shaking the container 27. dynamic roller 1
The waste liquid 28 adhering to the circumferential surface of 4 is removed. Waste liquid 2
8 is housed in the container 27. Note that if the circumferential surface of the swinging roller 14 is not sufficiently wet, the circumferential surface of the swinging roller 14 will be damaged by contact with the doctor blade 26. For this reason, as shown in the timing chart of FIG. 3, the doctor blade 26 completes spraying the cleaning liquid once over the entire length of the rollers, and the cleaning liquid 19 that is sequentially transmitted through each roller.
is operated by a suitable timer mechanism or the like so that it moves forward and contacts the swinging roller 14 after time t 2 when it reaches the circumferential surface of the swinging roller 14 .

During cleaning, the inking device 1 is disconnected from the pot roller 3 and the printing plate 6. Specifically, the calling roller 8 is brought into contact with the swinging roller 7 to break contact with the pot roller 3, and the contact between the plate surface 6 and the inking device 1 is broken by shifting the positions of the ink adhesion rollers 16 to 18. . Thereafter, as shown in the timing chart of FIG. 3, each roller of the inking device 1 is cleaned by operating each part. That is, at the cleaning start time t 0 , each roller of the inking device 1 is rotated for the cleaning processing cycle time (T 4 ).

効率的に行われる。 Further, the solenoid valve 25 is turned on for T 1 hour every time T 2 hours to supply the cleaning liquid 19 to the nozzle 20 . The nozzle 20 injects the cleaning liquid 19 four times during the continuous outward movement of the movable part 23 from A to B. Therefore, the cleaning liquid 19 is sprayed onto four separate areas along the longitudinal direction of the winding portions of the swinging roller 7 and the kneading roller 11. A much larger amount of cleaning liquid 19 is supplied to this cleaning liquid injection region compared to the conventional method, thereby greatly increasing the cleaning efficiency in this supply area. Note that in areas where the cleaning liquid 19 is directly supplied, slipping occurs due to the large amount of cleaning liquid 19, but in other roller areas, cleaning liquid 19 is not directly sprayed, so cleaning liquid flows in from the surrounding area. However, because the amount is small, there is no decrease in the frictional force that would cause slips. Therefore, no slip occurs between the swinging roller 7 and the kneading roller 11, and cleaning is performed efficiently.

Become. On the other hand, since there are parts between the rollers where the amount of cleaning liquid is small and the rotational frictional force is large, even if enough cleaning liquid is supplied to cause slips in some areas, slips do not occur as in the conventional rollers. Therefore, cleaning can be performed efficiently and with high reliability.
