Description
【考案の詳細な説明】 （産業上の利用分野） 本考案は、グラビア印刷機の分野に続し、特にその圧
胴に付着したゴミを取る装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention continues to the field of gravure printing machines, and more particularly to a device for removing dust adhering to the impression cylinder.
（従来の技術） グラビア印刷機にあっては、版胴に対する圧胴の表面
にごみが付着すると、その部分の印刷紙における版胴へ
の圧接に影響を及ぼし、印刷面に好ましくない結果を及
ぼすことがあった。(Prior Art) In a gravure printing machine, when dust adheres to the surface of the impression cylinder with respect to the plate cylinder, it affects the pressure contact of the printing paper to the plate cylinder at that portion, which gives an unfavorable result on the printing surface. There was an occasion.
これがため、従来にあっては、グラビア印刷機の圧胴
にごみが付着した場合、印刷機を止めて清掃していた。For this reason, conventionally, when dust adheres to the impression cylinder of the gravure printing machine, the printing machine is stopped and cleaned.
（考案が解決しようとする問題点） 以上のように、圧胴に付着したごみを除去するため
に、その都度機械を止めていたのでは、手数がかかるば
かりでなく、印刷の始動ごとに印刷が安定した状態に入
るまで、時間がかかり、無駄を生ずることとなった。(Problems to be solved by the invention) As described above, if the machine was stopped each time to remove the dust adhering to the impression cylinder, not only would it be time-consuming, but printing would be performed each time printing was started. It took time and wasted until it entered a stable state.
（問題点を解決するための手段） 本考案は、上記のような点を解決すべく案出されたも
ので、これがため、本考案にあっては、グラビア印刷機
の圧胴に対して、表面に弱粘着性を有するごみ取りロー
ルを、適宜圧接状態に設け、印刷中にあっても、これを
停止することなく、ごみ取りロールを圧胴に接触回転さ
せて、ごみを取るようにしている。(Means for Solving Problems) The present invention has been devised to solve the above-mentioned problems. Therefore, in the present invention, the impression cylinder of the gravure printing machine is A dust removing roll having a weak adhesive property on the surface is appropriately provided in a pressure contact state, and even during printing, the dust removing roll is brought into contact with the impression cylinder to rotate without stopping it to remove dust.
（実施例） 以下、本考案の実施例を図面に基づいて説明する。Embodiment An embodiment of the present invention will be described below with reference to the drawings.
図面において、（ａ）はグラビア印刷機における凹版

（ｃ）は、案内ロール（d1）を経て、版胴（ａ）と圧胴
（ｂ）との間を通って案内ロール（d2）を経て送り出さ
れる。圧胴（ｂ）の外面には、表面に弱粘着性を有する
ごみ取りロール（e1）、（e2）…が接離自在に設けられ
ていて、これは、圧胴（ｂ）の回転にともなって接触回
転するようになっている。In the drawing, (a) is an intaglio plate cylinder in a gravure printing machine, (b) is an impression cylinder in contact with the plate cylinder, and printing paper (c) passes through a guide roll (d 1 ) to form a plate cylinder (a). It is sent out through a guide roll (d 2 ) between the impression cylinder (b). On the outer surface of the impression cylinder (b), dust removal rolls (e 1 ), (e 2 ), etc., which have weak adhesiveness on the surface, are provided so that they can come in contact with and separate from each other. Along with it, it is designed to rotate in contact.
このごみ取りロール（e1）は、１個でも複数であって
もよく、また常に接していて回転していてもよいが、必
要なとき、すなわち、ごみ取りの際にだけ接するように
してもよい。The dust-removing roll (e 1 ) may be a single roll or a plurality of rolls, and may be always in contact with each other and rotating, but may be in contact only when necessary, that is, when removing dust.
さらに、駆動をとって圧胴回転と周速を同じにして接
するときの回転むらをなくすこともよい。Further, it is also possible to eliminate the rotational unevenness when the driving cylinder is driven and the peripheral speed is made the same as that of the impression cylinder so as to make contact.
そのごみ取りロール（e1）の接離も圧胴（ｂ）の半径
方向に直進してもよく、また円弧状に回動して接するよ
うにしてもよい。The dust removing roll (e 1 ) may be moved toward or away from the impression cylinder (b) in a straight line in the radial direction, or may be rotated in an arc shape to be in contact with the dust removal roll (e 1 ).
ごみ取りロール（e1）、（e2）…は、その表面が、ご
み、ほこり等で汚れた場合は、それを圧胴（ｂ）より離

アルコールでごみ等を除去すると、ロールは粘着力が回
復して反復使用することができる。If the surface of the dust removing rolls (e 1 ), (e 2 ) is dirty with dust, dust, etc., remove it from the impression cylinder (b) or remove it from the machine and wash it with water, or By removing dusts and the like with alcohol, the roll recovers its adhesive force and can be used repeatedly.
なお、（f1）、（f2）は印刷紙（ｃ）に接している静
電気除去の刷子である。Note that (f 1 ) and (f 2 ) are brushes for removing static electricity that are in contact with the printing paper (c).
（考案の効果） 本考案は、グラビア印刷機の版胴に対する圧胴の外面
に、表面に弱粘着性を有するごみ取りロールを圧接回転
するようにしたものであるから、グラビア印刷機のよう
な押圧によるインキ付着量が印刷に微妙な影響を与える
ものにあっても、常に圧胴面が清掃された状態にあるの
で、印刷機のインキの付着状態を常に一定にして良好な
印刷をすることができる。(Effects of the Invention) The present invention is configured such that a dust removing roll having a weak adhesive property on the outer surface of the impression cylinder with respect to the plate cylinder of the gravure printing machine is rotated by pressure contact, so that it is pressed like a gravure printing machine. Even if the amount of ink adhered by the machine has a delicate effect on printing, the impression cylinder surface is always cleaned, so it is possible to keep the ink adherence of the printing machine constant and perform good printing. it can.
しかも、ごみ取りに当たって、印刷機を止める必要が
ないから、印刷能力が低下することはない。また構成が
簡単であるから、手数のかからないものである。In addition, it is not necessary to stop the printing machine to remove dust, so that the printing ability does not decrease. Further, since the structure is simple, it does not take much time.
