本発明は新聞輪転印刷機における断裁見当制御方法に関
するものである。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a cutting register control method in a newspaper rotary printing press.
（従来の技術）
一般に、新聞輪転印刷機は第３図に示すように、走行線
１０がリールスタンド１１に装着され、その走行紙１０
の一端が複数のガイドローラ１２及びダンサ−ローラ１
３を経由して印刷ユニット１４に供給される。(Prior Art) Generally, in a newspaper rotary printing machine, as shown in FIG. 3, a running line 10 is attached to a reel stand 11, and the running paper 10
One end has a plurality of guide rollers 12 and dancer rollers 1.
3 to the printing unit 14.
そして、この印刷ユニット１４を通過した上記走行紙１

設置されるコンペンセータ１８を経由し、三角板ドラグ
ローラ１９に供給される。Then, the running paper 1 that has passed through this printing unit 14
0 is slit into half width, for example, by the intermediate drag roller 15, and when one of the webs 101 passes through the compensator 16 of the straight section, the other web 102 is installed close to the turner 17 and a part of the turner. It is supplied to a triangular plate drag roller 19 via a compensator 18.
これら各コンペンセータ１６及び１８を経由した上記走

手動式に調整し、断裁見当を制御していた。このため、
その調整作業が非常に煩雑で作業性が悪く、走行紙１０
に多（の損紙を生じる欠点を有するものである。By the way, when controlling the cutting register of the running paper 10 in the above-mentioned conventional newspaper rotary printing machine, the operator visually determines the error (deviation amount) of the cutting register at the outlet of the feeder 22,
The compensators 16 and 18 were manually adjusted in accordance with the amount of deviation to control the cutting register. For this reason,
The adjustment work is very complicated and the workability is poor.
This method has the disadvantage of causing a large amount of waste paper.
また、断裁見当制御を自動化するため、ウェブに特別な

慮を必要としないものである。The marks printed on the web 101 are located at positions as indicated by 42 or 43 in FIG. The figure is an explanatory diagram showing a newspaper, where 41 is the whole newspaper, 42 is a machine number mark, and 43 is a frame line. The machine number mark 42 is originally intended to indicate the number of the printing unit 7 where the page was printed, and the frame line 43 is always printed on any newspaper, and both indicate the number of the printing unit 7 where the page was printed. Therefore, no special consideration is required.
本発明にあっては、これらのマークをマーク検出器３１
の検出対象としようとするものである。In the present invention, these marks are detected by a mark detector 31.
This is the target of detection.
第１図において、走行紙１０は需用２２にて断裁される

操作すれば、断裁見当を一定に保つことができることに
なる。In FIG. 1, the running paper 10 is cut at the cutting edge 22, but since the geometric distance between the cutting edge 22 and the mark detector 31 is constant, the cutting target at the cutting edge 22 changes. Then, the signal detected by the mark detector 31 also changes by the same amount. Therefore, if the compensator 18 is operated via the controller 29 so as to keep the phase difference between the rotation signal of the feeder 22 and the detection signal of the mark detector 31 constant, the cutting register can be kept constant. Become.
なお、第１図においてはウェブ１０１のみを制御する場
合を示したが、全てのウェブを同時に制御することも、
マーク検出器を複数個用いることにより同様に可能とな
