Object of the Invention (Field of Industrial Application) The present invention provides a drying device for evaporating a solvent from an ink film in an offset rotary printing press that prints on a strip of paper using heat set ink, and a drying device for evaporating a solvent from an ink film, and It is related to a cooling device that cools the strip-shaped printed material that has passed through the device.

の要望も高まって印刷速度はますます高速化している。(Prior Art) A rotary offset press has higher productivity and labor savings than a sheet-fed printing press, and is capable of printing a large amount of paper on a thin web in a short prepress preparation time. Due to its characteristics, offset rotary printing has recently been increasingly adopted, and demands for improved characteristics have also increased, resulting in increasingly faster printing speeds.

されたインキ皮膜中から溶剤を蒸発させることで乾燥を
行なっている。Heatset inks are used in rotary offset printing. Heat set ink consists of a coloring material such as a pigment and a vehicle such as a resin or a solvent, and is dried by evaporating the solvent from the printed ink film.

に持って行くのである。For this reason, as shown in Figure 3, strip-shaped printed matter (9
) is used, which is a drying oven αυ that blows hot air on the
Immediately after passing through the drying oven αυ, the printed material strip (9) is still at a high temperature, and the resin in the printed ink film is still softened, so it has not reached the so-called set state. After passing through the drying oven aυ, the strip of paper is then wrapped around a water-cooled cooling cylinder (121) to cool it to near room temperature and brought to a so-called "set" state where no ink sticks to it even when touched. be.

び冷却シリンダα２の上面を覆うフード０東を設けて吸
引排出するのが普通である。In the evaporation process in the drying oven aυ, it is not necessary to evaporate all of the solvent, and approximately half of the solvent remains in the ink film. Since the paper strip leaving the drying oven is usually at a high temperature of 100° C. or higher, the solvent in the ink film has a high vapor pressure and continues to evaporate outside the drying oven. Since the ambient temperature outside the drying oven is lower than inside the oven, the vaporized solvent is cooled and becomes colored mist. If left as is, the inside of the printing chamber will become contaminated, so it is common practice to provide a hood 0 east that covers the top surface of the strip-shaped printed material (9) and the cooling cylinder α2 to suck and discharge the printed material.
（解決しようとする問題）
上述の帯状印刷物の上面及び下面には、紙面に密着して

層から外周の雰囲気へ溶剤ミストの拡散が行なわれるの
である。(Problem to be Solved) A boundary layer exists on the upper and lower surfaces of the above-mentioned strip-shaped printed matter in close contact with the paper surface. Since the paper strip is still at a high temperature, solvent vapor continues to enter the boundary layer from the ink film on the surface of the paper strip, and the boundary layer contains a high concentration of solvent vapor in the gas phase and solvent in the form of a mist. The solvent mist is diffused from the boundary layer into the surrounding atmosphere.
これら境界層内の溶剤蒸気は冷却されて液化すれば、帯
状紙が多孔質であるため毛管現象により、帯状紙に付着
した分は再び吸収される。When the solvent vapor in these boundary layers is cooled and liquefied, the amount adhering to the paper strip is absorbed again by capillary action since the paper strip is porous.
従来の印刷速度においては冷却シリンダαのによって帯
状印刷物が冷却されると、境界層の溶剤も冷却吸収され
、インキ皮膜中の樹脂も冷えて粘度を増して固化し、「
セット」が成立して来た。At conventional printing speeds, when the printed strip is cooled by the cooling cylinder α, the solvent in the boundary layer is also cooled and absorbed, and the resin in the ink film also cools, increases its viscosity, and solidifies.
A set was established.
しかるに近時印刷速度の上昇につれて状況は変って来た
のである。However, as printing speeds have increased in recent years, the situation has changed.
１）速度が速くなったために帯状印刷物が乾燥炉を出て
冷却シリンダに接するまでの時間が短かくなり、そのた
め帯状紙の空冷による温度降下が少なく、乾燥炉を出た
あとも溶剤の蒸発が強く持続される。1) Due to the increased speed, the time it takes for the strip of printed matter to leave the drying oven and come into contact with the cooling cylinder is shortened, so there is less temperature drop due to air cooling of the strip, and the solvent evaporates even after leaving the drying oven. Strongly sustained.
２）単位時間当りの印刷量が多いため、単位時間当りの
溶剤蒸発量も多くなっている。2) Since the amount of printing per unit time is large, the amount of solvent evaporated per unit time is also large.
３）帯状印刷物の下面及び冷却シリンダ上面の接触点に
到るまでの境界層は、質量と速度とを持っていて、その
運動量によって接点以後の両者（帯状印刷物と冷却シリ

（９）は張力によって発生する冷却シリンダα２への接
触圧を持っており、進入しようとする空気を押し戻す作
用をもっている。3) The boundary layer up to the point of contact between the lower surface of the strip-shaped printed material and the upper surface of the cooling cylinder has mass and velocity, and due to its momentum, it tends to enter between the two (the strip-shaped printed material and the cooling cylinder) after the contact point. On the other hand, the strip-shaped printed matter (9) has a contact pressure against the cooling cylinder α2 generated by tension, and has the effect of pushing back the air that is about to enter.
高速になると運動量が増加して空気層が両者の間に進入
する「クサビ効果」が高くなるのに対して、帯状印刷物
の接触圧は遠心力によって減少する。As the speed increases, the momentum increases and the "wedge effect" in which an air layer enters between the two becomes stronger, while the contact pressure of the printed strip decreases due to centrifugal force.
などの理由により冷却シリンダαりと帯状印刷物（９）
との間に多量の溶剤蒸気を含んだ空気層が存在するに到
る。このため、
（１）帯状印刷物は不良導体の空気層の存在のために冷
却効果が減少する。Due to reasons such as cooling cylinder α and band-shaped printed matter (9)
An air layer containing a large amount of solvent vapor exists between the two. For this reason, (1) the cooling effect of printed strips is reduced due to the presence of air layers of poor conductors;
（２）上記空気層の冷却シリンダに接触する側は冷える
ので、溶剤蒸気は液化してシリンダ表面に付着する。(2) Since the side of the air layer that contacts the cooling cylinder cools, the solvent vapor liquefies and adheres to the cylinder surface.
（３）冷却シリンダ表面に付着し蓄積した溶剤は帯状印
刷物のインキ皮膜を溶解して印刷品質を劣化させる。(3) The solvent that adheres to and accumulates on the surface of the cooling cylinder dissolves the ink film of the strip-shaped printed matter and deteriorates the printing quality.
すなわち、乾燥炉では必要な溶剤蒸発量を維持している
にも拘らず、見掛は上乾燥が良゛くないという問題を発
生している。That is, although the drying oven maintains the necessary amount of solvent evaporation, the problem arises that the drying is apparently not good.
上記の問題点を解決するための方策として（１）乾燥炉
を大きく設計して問題を解決する方法はあるが、コスト
の面で不適当であることはいうまでもない。As a method for solving the above problems, there is a method (1) of designing a large drying oven to solve the problem, but it goes without saying that this is inappropriate in terms of cost.
（ｌり帯状印刷物と冷却シリンダの接触点近傍を真空化

気量の絶対量を制限する。これもコスト面で不当である
。(The vicinity of the contact point between the strip-shaped printed matter and the cooling cylinder is placed in a vacuum atmosphere to limit the absolute amount of air that enters due to the "wedge effect.") This is also unreasonable in terms of cost.

。(Operation of the present invention) Since the present invention has the above-described configuration, by blowing cold air on the upper and lower surfaces of the high-temperature printed strip after exiting the drying oven, the boundary layer on the upper and lower surfaces of the printed strip is stripped off, and the boundary layer is removed.

剤蒸気やミストを除去することができる。C. Effects of the Invention According to the present invention: 1) By blowing cold air from the nozzle onto the strip-shaped printed material, most of the boundary layer containing solvent vapor can be stripped off, and much of the solvent vapor and mist can be removed.

く抑制する。2) Blowing high-speed cold air onto the printed strip also promotes material transfer from the printed strip.
The solvent, which has a high vapor pressure in the area hit by the cold air, is evaporated and the latent heat of evaporation cools the strip-shaped printed matter.In addition to the temperature drop due to heat transfer from the cold air, subsequent evaporation of the solvent is greatly suppressed.
３）従来帯状印刷物の下側には溶剤ミストが停滞する傾

炉内を冷やすという悪影響をも防ぐことができる。5) The direction of the cold air blown from the nozzle onto the strip of printed matter is diagonally between the upstream direction and the outer edge direction of the strip of paper running, and the boundary layer of the strip of printed material is traveling downstream, so scavenging The direction of the cooled air is almost perpendicular to the traveling direction of the belt-shaped printed matter, which is the combination of both, and is directed toward the outer edge. Therefore, it is possible to provide a scavenging air suction chamber in a place where it does not interfere with the running of the strip-shaped printed matter, and if the scavenging air is directed upstream, it is possible to prevent the negative effect of being sucked into the drying oven and cooling the inside of the drying oven. I can do it.
