A dampening water circulation system for printing that simplifies the return water equipment from the saucer provided on the plate cylinder side, avoids clogging, and allows smooth return flow without causing foaming. The aim is to provide equipment.

して印刷を行わせるものである。(Prior art) In offset printing, etc., an ink roll and a dampening water roll are arranged on the printing plate cylinder roll, and the dampening water roll is supplied with dampening water from a saucer via a water source roll and an intermediate roll. The ink is supplied to an appropriate amount using the dampening water roll, and printing is performed using the plate cylinder roll while transferring and supplying ink from the ink roll under water supply conditions from the dampening water roll. In other words, the ink is transferred and deposited under conditions where areas where ink should not be deposited are moistened with dampening water, thereby eliminating the deposition of oil-based ink and creating a proper ink deposition state for printing. It is something that allows people to do this.

水循環室に受けることが示されている。 However, in the past, dampening water as described above was returned by gravity from a water boat, for example, as disclosed in Utility Application No. 59-81560 (Utility Model Application No. 1986-194525) and Japanese Patent Application No. 1986-1945.
-157360 shows that unused water from a water boat attached to a water fountain roller is received by a pipe into a dampening water circulation chamber.

管路内における閉塞をなからしめる。 However, the above-mentioned dampening water is usually mixed with etchant and other additives, and when attempting to return such dampening water from the above-mentioned saucer to the adjustment tank under natural flow, clogging is likely to occur. . That is, generally, a large number of the above-mentioned saucers (water vessels), such as 5 to 6, are provided on the side of the dampening water roll, and each return pipe from them is bent accordingly to reach the adjustment tank. 10 to 20 in any case.
It has to be necessarily a small diameter of about mm,
In addition, each tray is contaminated with paper dust and other substances from the plate cylinder of the printed matter, and such reflux water can cause solid matter to adhere to the inner surface of the narrow and curved return pipe, causing a blockage. expensive. Therefore, instead of the conventional gravity flow method using a simple reflux pipe, in recent years, a pump has been used to suck and recirculate the reflux water from the saucer, or as in Japanese Patent Application Laid-Open No. 78414/1983, an ejector has been used to collect water from the saucer. It has been proposed to provide forced reflux to the regulating tank. That is, stable reflux is achieved by forced reflux, and blockages in the reflux pipe are eliminated.

難い。(Problems to be solved by the invention) In the case of the above-mentioned conventional water cannons that simply allow the water to flow back down naturally, a large number of relatively small-diameter, curved pipes from each water canister are installed in a row to reach the adjustment tank. In addition, it is difficult to smoothly circulate dampening water that has increased under recent high-speed printing press operating conditions. It is also difficult to put it into practical use.

りが乱れざるを得ないことになる。 In addition, if the water in the saucer is refluxed using a pump or an ejector as described above, not only will an extra pump and motor be required, but dampening water will flow inside the reflux pipe. flowing rapidly,
In particular, since the dampening water mixes with air and flows, the dampening water foams or the surface of the dampening water in the saucer becomes undulating. The amount of dampening water applied varies in the water source roll that contacts the water surface and applies water to the plate cylinder portion. Fluctuations in the amount of dampening water applied by the water base roll inevitably cause unevenness in the supply of dampening water to the plate cylinder, making it impossible to maintain the desired balance between dampening water and ink on the plate cylinder. As a result, the print finish is inevitably disturbed.

において起泡することとなる。 In addition, as mentioned above, the return dampening water pumped by the pump or ejector will also cause foaming in the adjustment tank, creating conditions that are likely to cause foaming at the very least. The dampening water under easy conditions is sent to the receiving tray on the printing press side by a pump, and foams in the receiving tray on the side of the printing press.
従つてこのような場合には消泡剤などを添加し

コストが高くなり、しかも好ましい印刷仕上がり
を得難いこととなる。 Therefore, in such a case, it may be possible to add an antifoaming agent or the like to prevent foaming on the surface of the dampening water in the saucer as described above, and to suppress ripples.
Naturally, the addition of such an antifoaming agent increases costs, and what is undesirable is that the antifoaming agent component added in this manner does not reach the plate cylinder through the dampening water. It is clear that the antifoaming agent component acts as an emulsifier for the ink on the plate cylinder and emulsifies fine ink adhering to the plate cylinder, thereby deteriorating the adhesion of the ink to the printing paper surface and the finish of printing. That is, the running cost for printing becomes high, and moreover, it becomes difficult to obtain a desirable print finish.

あつても閉塞を生ずることがない。(Function) By receiving the return water from the saucer into the return water chamber through the gravity flow pipe, the gravity flow pipe becomes short and small to the return water chamber provided along the arrangement direction of each saucer, and the overall equipment is improved. and without the need for force means such as pumps or ejectors,
Easily removed from the saucer due to natural gravity conditions. That is, the distance to reach this water chamber is relatively short and can be made straight, so even if it is a natural flow, no blockage will occur.
上記のように自然流下で受皿内の湿し水が抜き

及ぶことを完全に防止する。 The dampening water received in the water chamber forms a free water surface in the water chamber, and even if the free water surface formed in this way is pumped and returned to the adjustment tank, there will be pulsations or waves due to the forced force of the pump. Other influences are effectively absorbed on the free water surface and are completely prevented from reaching the dampening water in the saucer.

し、良好な印刷仕上がりを得しめる。 By eliminating undulations and foaming in the saucer, the use of antifoaming agents is eliminated, and the influence of the antifoaming agent components on the plate cylinder, that is, the emulsification of ink, is eliminated, resulting in a good print finish. .
