に放熱機能を有さないものを使用していた。2. Description of the Related Art In general, a lithographic offset printing machine uses a large number of ink rollers 1 for supplying ink 11 to the plate surface, as shown in FIG.
2, several water rollers 13 and a plate cylinder 14. Blanket body 16. It is composed of an impression cylinder 16. Ink 1
1 is a high viscosity paste-like 2-base ink, which is drawn out little by little by a source roller 17 and transferred to the row of ink rollers 12 by a drawing roller 18 that swings as shown by the arrow. The ink rollers 12 are made up of a combination of metal rolls and rubber rolls, and the ink is subjected to large pressure and shear force between the rollers, and immediately after leaving the rollers, it is torn between the two rollers and gradually The ink is repeatedly transferred to the next roll while being stretched into a uniform thin film, and finally the ink is supplied to the plate cylinder 14. As shown in FIG. 3, the metal ink roller used here does not have a heat dissipation function.
発明が解決しようとする問題点
インキローラでインキが練られる際に、インキローラの
機械エネルギーの一部はインキの熱エネルギーの一部に
変換され、インキの温度は次第に上昇する。Problems to be Solved by the Invention When ink is kneaded with an ink roller, part of the mechanical energy of the ink roller is converted into part of the thermal energy of the ink, and the temperature of the ink gradually increases.
インキの温度が上昇すると、その粘度が減少するととも
に、その流動特性、乾燥特性、皮膜特性が大きく変化す
るため、印刷条件が一定とならず、３ベーノ
印刷物の仕上がりが安定し々かった。As the temperature of the ink increases, its viscosity decreases, and its flow characteristics, drying characteristics, and film characteristics change significantly, so printing conditions are not constant, and the finish of 3-bene prints is unstable.
問題点を解決するための手段
本発明は上記問題点を解決するため、インキローラ内部

イプ作動媒体を充填するものである。Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a cooling water flow path inside the ink roller, and also provides a space between the cooling water flow path and the outer surface of the ink roller. It is used to fill the heat pipe working medium.
作 用
上記した手段により、インキがインキローラで練られる
際に発生する熱は、インキローラ外表面側のヒートパイ
プ作動媒体が蒸発することによって吸熱され、インキの
温度は一定に保持できる。Effect: By the means described above, the heat generated when the ink is kneaded by the ink roller is absorbed by evaporation of the heat pipe working medium on the outer surface of the ink roller, and the temperature of the ink can be kept constant.
実施例 以下に、本発明の一実施例を図面により説明する。Example An embodiment of the present invention will be described below with reference to the drawings.
第１図はインキローラの一部破断斜視図である。FIG. 1 is a partially cutaway perspective view of the ink roller.
インキローラ１の中心部に冷却水流路２が設けられ、イ
ンキローラ１端部の回転軸３の中空部と連通している。A cooling water flow path 2 is provided in the center of the ink roller 1 and communicates with a hollow portion of the rotating shaft 3 at the end of the ink roller 1.

、一定温度に保持された冷却水が循環している。冷却水
流路２とインキローラ外表面部との間に空間４が設けら
れ、空間４内部にヒートパイプ作動媒体６が適当量光て
んされている。The cooling water flow path is piped out to the outside at the end of the rotating shaft 3 through a rotatable seal. Cooling water maintained at a constant temperature is circulated in the cooling water flow path 2 . A space 4 is provided between the cooling water flow path 2 and the outer surface of the ink roller, and a suitable amount of a heat pipe working medium 6 is filled inside the space 4.
今、インキローラが回転し、インキが練られている場合

却水流路２の外壁に凝縮し、冷却水に熱を伝える。Now, when the ink roller is rotating and the ink is being mixed, the temperature of the ink will rise, but the temperature of the outer surface of the ink row 21 that is in contact with the ink will also rise at the same time, and the outer surface of the ink roller in the space 4 will rise. The heat pipe working medium 6 in contact with evaporates. At this time, heat is removed from the outer surface of the ink roller and the ink by the latent heat of evaporation, making it possible to suppress an increase in the temperature of the ink. The evaporated working medium 6 condenses on the outer wall of the cooling water flow path 2 and transfers heat to the cooling water.
冷却水に与えられた熱は、外部へ取りだされる。The heat given to the cooling water is taken out to the outside.
冷却水流路２を流れる冷却水の温度を所定の値に保持す
ることにより、インキローラ外表面部の温度が上昇すれ
ば、作動媒体が蒸発し、インキローラ外表面部とそれに
接するインキの温度を一定に保つことができる。By maintaining the temperature of the cooling water flowing through the cooling water flow path 2 at a predetermined value, when the temperature of the outer surface of the ink roller increases, the working medium evaporates, and the temperature of the outer surface of the ink roller and the ink in contact with it increases. can be kept constant.
６ベー／
作動媒体は、制御したいインキの温度（→蒸発温度）と
インキローラ空間部４の圧力条件によって種々の媒体（
フレオン、水等）が利用できる。6 base / The working medium can be various media (
Freon, water, etc.) can be used.
本発明はインキローラの中に単に冷却水流路を設けて熱
伝導によって熱の伝達を行なわせる場合と較べて、蒸発
及び凝縮熱伝達によるため熱伝達係数が極めて高く、熱
の伝播速度が早くなり、その結果応答性にすぐれた温度
制御を行なうことができる。The present invention uses evaporation and condensation heat transfer, so the heat transfer coefficient is extremely high, and the speed of heat propagation is faster, compared to the case where a cooling water flow path is simply provided in the ink roller and heat is transferred by heat conduction. As a result, temperature control with excellent responsiveness can be performed.
尚、インキローラ空間部の外表面側は、作動媒体を含み
易い多孔質のウィック、あるいはメツシュ等をとりつけ
れば一層効果的である。It is more effective to attach a porous wick or mesh that easily contains the working medium to the outer surface of the ink roller space.
又、本発明を実施したインキローラは、オフセット印刷
機の多数のインキローラ全数に設けることが望ましいが
、一部分のみ設けてもよい。Furthermore, although it is desirable that the ink rollers embodying the present invention be provided in all of the many ink rollers of an offset printing machine, they may be provided in only some of the ink rollers.
発明の効果
本発明によれば、版面へ供給するインキの温度を一定に
することができ、インキの流動特性、乾燥特性、皮膜特
性が一定し、印刷品質の安定化が図れる。Effects of the Invention According to the present invention, the temperature of the ink supplied to the printing plate can be kept constant, the flow characteristics, drying characteristics, and film characteristics of the ink can be kept constant, and printing quality can be stabilized.
