Description
【0001】[0001]
この考案は、印刷機の版胴に関するものである。 The present invention relates to a plate cylinder of a printing machine.
【0002】[0002]
版胴に対する印刷版の取付けには、両面粘着テープを用いて版胴に全面接着す る方法や、版胴の外周に設けた溝内にクランプを取付け、そのクランプによって 版胴の周囲に巻付けられた印刷版の両端部を挾持する方法が従来から知られてい る。 To attach the printing plate to the plate cylinder, double-sided adhesive tape is used to adhere the entire surface to the plate cylinder, or a clamp is installed in the groove provided on the outer periphery of the plate cylinder, and the clamp wraps around the plate cylinder. A method of holding both ends of a printing plate thus prepared is conventionally known.
【0003】[0003]
ところで、いずれの方法も印刷版の取付け、取外しが困難であって、印刷版の 交換に非常に手間がかかると共に、取外しの際に印刷版を損傷させることが多く 、また、装着した印刷版のねじれ調整にも手間がかかる問題がある。 By the way, with either method, it is difficult to attach and detach the printing plate, and it takes a lot of time to replace the printing plate, and it often damages the printing plate when detaching it. There is also a problem that it takes time to adjust the twist.
【0004】 この考案は、上記の従来の問題点を解決し、印刷版の交換およびねじれ調整が 容易に行なえる版胴を提供することを技術的課題としている。This invention has a technical problem to solve the above-mentioned conventional problems and to provide a plate cylinder that allows easy exchange of a printing plate and adjustment of twist.
【0005】[0005]
上記の課題を解決するために、この考案においては、内部が中空とされた円筒 形胴体の外周全体に多数の吸引孔を均一に形成し、胴体の両端部に設けられた版 胴軸の一方に胴体内部に吸引力を付与する吸引通路を設けた構成を採用したので ある。 In order to solve the above-mentioned problems, in the present invention, a large number of suction holes are uniformly formed on the entire outer periphery of a hollow cylindrical body, and one of the plate cylinder shafts provided at both ends of the cylinder is provided. This is because a suction passage is provided inside the body to apply suction force.
【0006】[0006]
上記の構成から成る版胴に印刷版を取付けるには、版胴の周囲に印刷版を巻付 け、吸引通路に吸引力を付与し、吸引孔の全体に吸引力を付与して印刷版を吸着 する。 To attach the printing plate to the plate cylinder configured as described above, wrap the printing plate around the plate cylinder, apply suction force to the suction passage, and apply suction force to the entire suction hole to form the printing plate. Adsorb.
【0007】[0007]
以下、この考案の実施例を添付図面に基づいて説明する。 An embodiment of the present invention will be described below with reference to the accompanying drawings.
【0008】 図1および図2に示すように、内部が中空とされた円筒形の胴体1は両端に版 胴軸2a、2bを有し、その版胴軸2a、2bが印刷機のサイドフレーム3で回 転自在に支持されている。As shown in FIGS. 1 and 2, a cylindrical body 1 having a hollow inside has plate cylinder shafts 2a and 2b at both ends, and the plate cylinder shafts 2a and 2b are side frames of a printing machine. It is rotatably supported at 3.
【0009】 胴体1の外周には外径面から内径面に貫通する多数の吸引孔4が均一に形成さ れている。また、胴体1の一方の版胴軸2bには軸方向に延びる吸引通路5が設 けられ、その吸引通路5は版胴軸2bの軸端面で開口している。A large number of suction holes 4 are uniformly formed on the outer periphery of the body 1 so as to penetrate from the outer diameter surface to the inner diameter surface. A suction passage 5 extending in the axial direction is provided on one plate cylinder shaft 2b of the body 1, and the suction passage 5 is open at the shaft end surface of the plate cylinder shaft 2b.
【0010】 上記版胴軸2bの端部には軸受6を介してホースジョイント7が回転自在に取 付けられ、そのホースジョイント7に吸引ホース8が接続されている。A hose joint 7 is rotatably attached to the end of the plate cylinder shaft 2b via a bearing 6, and a suction hose 8 is connected to the hose joint 7.
【0011】 実施例で示す版胴は上記の構造から成り、その版胴に対する印刷版の取付けに 際しては、図3に示すように、胴体1の外周に印刷版Aを巻付けてから吸引通路 5に吸引力を付与するか、あるいは、吸引通路5に吸引力を付与する状態で胴体 1の外周に印刷版Aを巻付ける。The plate cylinder shown in the embodiment has the above-mentioned structure, and when mounting the printing plate on the plate cylinder, the printing plate A is wound around the outer periphery of the body 1 as shown in FIG. The printing plate A is wound around the outer periphery of the body 1 while applying suction force to the suction passage 5 or while applying suction force to the suction passage 5.
【0012】 ここで、印刷版Aは、胴体1の吸引孔4の全体を覆うことができる大きさとさ れている。Here, the printing plate A is sized so as to cover the entire suction hole 4 of the body 1.
【0013】 上記の印刷版Aを胴体1に巻付けた状態において、吸引通路5に吸引力を付与 すると、その吸引力は各吸引孔4に作用するため、印刷版Aは吸着され、胴体1 の外周に巻付けた状態に保持される。When a suction force is applied to the suction passage 5 in a state where the printing plate A is wound around the body 1, the suction force acts on each suction hole 4, so that the printing plate A is sucked and the body 1 It is kept wound around the outer periphery of the.
【0014】 印刷版Aのねじれ調整に際しては、吸引孔4に対する吸引力を弱め、あるいは 吸引を解除した状態で印刷版Aを手動で移動させる。When adjusting the twist of the printing plate A, the suction force on the suction holes 4 is weakened, or the printing plate A is manually moved in a state where the suction is released.
【0015】[0015]
以上のように、この考案に係る版胴においては、吸引孔に付与する吸引力によ って印刷版を吸着するようにしたから、印刷版の取付け、取外しが容易であり、 印刷版の交換作業を短時間に能率よく行なうことができると共に、印刷版を損傷 させることなく取外すことができる。 As described above, in the plate cylinder according to the present invention, the printing plate is attracted by the suction force applied to the suction hole, so that the printing plate can be easily attached and detached, and the printing plate can be replaced. Work can be done efficiently in a short time, and the printing plate can be removed without damaging it.
【0016】 また、吸引孔に対する吸引力を弱め、あるいは吸引を解除することによって印 刷版を版胴の外周に沿って移動させることができるため、印刷版のねじれ調整も 容易である。Further, since the printing plate can be moved along the outer periphery of the plate cylinder by weakening the suction force to the suction hole or releasing the suction, it is easy to adjust the twist of the printing plate.
【0017】 さらに、多数の吸引孔を胴体の全体にわたって均一に形成したので、印刷版の 内面全体が胴体の外周に密着する取付け状態を得ることができ、きわめて精度の 高い印刷を行なうことができる。Furthermore, since a large number of suction holes are formed uniformly over the entire body, it is possible to obtain a mounting state in which the entire inner surface of the printing plate is in close contact with the outer periphery of the body, and printing with extremely high accuracy can be performed. .
【0018】 また、印刷版の長さが胴体の外径面の周長より短かい場合は、連続紙に印刷さ れる図柄の間隔が大きくなるが、本願の場合、胴体の外径面の周長に等しい印刷 版を用いることができるため、図柄間の間隔が小さい印刷が可能となる。Further, when the length of the printing plate is shorter than the circumference of the outer diameter surface of the body, the interval between the patterns printed on the continuous paper becomes large, but in the case of the present application, the circumference of the outer diameter surface of the body is large. Since a printing plate equal to the length can be used, it is possible to print with a small space between patterns.
