本発明は、サイズ交換式輪転機における天地見当設定方
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for setting vertical register in a size-changeable rotary press.
輪転印刷機において、印刷サイズ及びミシン目加工、折
り加工寸法が固定のものは、印刷その他のユニットの天
地見当は１つということになり、一度設定すれば各仕事
毎の初期設定は不要である。しかし交換サイズ式のもの
は、例えば印刷部では版胴その他を交換するため、各版
胴毎の位相が狂ってしまう。これを位相が合ったところ
で各版胴を交換するのは大変な作業となる。In rotary printing presses, if the printing size, perforation processing, and folding processing dimensions are fixed, there is only one vertical orientation for printing and other units, and once set, there is no need to make initial settings for each job. . However, in the exchangeable size type, for example, in the printing section, plate cylinders and other parts are replaced, so the phase of each plate cylinder becomes out of alignment. It is a difficult task to replace each plate cylinder once the phases match.
このため従来は実際に印刷し、基準となる絵柄を順次合

この天地見当合わせは版胴を交換するたびに行なわなけ
ればならず、しかも試削を必要とするため各仕事毎に上
記天地方向の見当合わせに多大の時間を要するという問
題があった。For this reason, conventionally, the vertical register of each pattern was matched by actually printing and aligning the reference patterns one after another.
This vertical registration must be performed every time the plate cylinder is replaced, and trial cutting is required, which poses a problem in that it takes a great deal of time to perform the vertical registration for each job.

2+... is detected, and then the paper path length Ll+L2+... from the reference point of the rotary unit on the reference side to the reference point of the rotary unit on each vertical registration side and the phase difference length lI+1 are detected.
Calculate the difference between 2+..., l B2 +..., and divide the paper path difference LI+I4+... by the circumferential length l of the 6th cylinder. Since it is corrected through a mechanism, the phase difference between the reference point of the rotary unit on the reference side and the reference point of the other rotary unit that requires vertical registration can be adjusted in pulse terms using a proximity switch, etc. By detecting this and performing the above calculations using a CPU, etc., it is possible to automatically perform vertical registration with respect to the reference rotary part, and correction can be made by simply rotating each rotary part once or twice. Compared to the conventional method of printing, processing, and matching each other, there is no paper loss, and the work time can be greatly reduced.
