Description
【考案の詳細な説明】 (産業上の利用分野) 本考案は、枚葉印刷機の圧胴洗浄装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an impression cylinder cleaning device for a sheet-fed printing press.
(従来の技術) 枚葉印刷機による印刷の場合、印刷に用いられる紙サ
イズは長さ・巾ともに大きいものから小さいものまで各
種あり、これが1台の印刷機に適用される。(Prior Art) In the case of printing by a sheet-fed printing press, there are various paper sizes used for printing, from large to small in both length and width, and this is applied to one printing press.
印刷は、圧胴とゴム胴との間で紙をプレスすることに
より、インキがゴム胴より紙面へと転写されることによ
って行われる。Printing is performed by pressing the paper between the impression cylinder and the blanket cylinder to transfer the ink from the blanket cylinder to the paper surface.
ここで、圧胴の表面積より小さい紙に印刷する場合、
紙面よりはみ出た圧胴表面はゴム胴と直接、当接するこ
ととなり、ここには残インキが付着する。圧胴表面に付
着・堆積した残インキは、次回に大きな紙を印刷すると
き、その裏面(圧胴に接する面)に逆付着し、紙面を汚
すことになる。Here, when printing on paper smaller than the surface area of the impression cylinder,
The surface of the impression cylinder protruding from the surface of the paper comes into direct contact with the blanket cylinder, and residual ink adheres thereto. The residual ink that has adhered to and accumulated on the surface of the impression cylinder is reversely adhered to the back surface (the surface in contact with the impression cylinder) of the large paper next time, and stains the paper surface.
このため、小さいサイズの紙を印刷した後で大きいサ
イズの紙に紙サイズを切替えて印刷するときには、必ず
圧胴表面を清拭し、残インキ(紙粉等を含む。)を除去
しておく必要がある。Therefore, when the small size paper is printed and then the large size paper is printed by switching the paper size, the surface of the impression cylinder must be wiped to remove the residual ink (including paper dust and the like). There is a need.
