本発明は、交換胴形の輪転印刷機における着ローラ装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a forming roller device in an exchange cylinder type rotary printing press.
高級印刷を行う輪転印刷機には、見当精度を向上するた
めに、版ヒネリ装置が装備されている。これは製版精度
、版の折り曲げ精度などの影響により、版胴への版の取
り付けが、各色の絵柄相互がずれていた場合にこれを修
正する装置であり、その修正の方法としては、多くの機
械では版胴の両端部を支承する軸受部の一方の軸心をず
らすようにした方法を採用している。Rotary printing presses that perform high-grade printing are equipped with a plate twisting device to improve registration accuracy. This is a device that corrects when the patterns of each color are misaligned when the plate is attached to the plate cylinder due to the effects of plate-making accuracy, plate folding accuracy, etc. There are many ways to correct this. The machine uses a method in which the axis of one of the bearings that support both ends of the plate cylinder is shifted.
このような場合、いままで版面に均一に接触していた着
ローラは、版胴にヒネリを加えたことにより、これの片
側が強く接触したり、離れてしまったりする。着ローラ
は通常１つの版胴に２〜４本接触しているが、版胴の軸
心をずらす位置と、版胴上の着ローラの位置により、こ
れの接触の変化量は各着ローラで変わってくる。In such a case, one side of the roller, which had been in uniform contact with the plate surface, may come into strong contact with the plate cylinder or come apart due to the twisting of the plate cylinder. Normally, two to four forming rollers are in contact with one plate cylinder, but depending on the position where the axis of the plate cylinder is shifted and the position of the forming roller on the plate cylinder, the amount of change in contact between each forming roller may vary. It's going to change.
版胴が１種類の固定胴形の場合は、着ローラの付く位置
が常に同じため、版胴と同径のストッパを版胴と一体と
なる部分に取付け、着ローラよりねじ捧を出してそのス
トッパに当て、ねじ捧により版と着ローラの接触圧を調
整するようになっている。If the plate cylinder is a fixed cylinder type, the position of the forming roller is always the same, so a stopper with the same diameter as the plate cylinder is attached to the part that is integrated with the plate cylinder, and the screw thread is extended from the forming roller and then The contact pressure between the plate and the forming roller is adjusted by applying it to a stopper and using a screw.
これにより、版胴のヒネリを行なった場合でも、ストッ
パが版胴と同じ動きをするため、着ローラもストッパを
介して追随し、常に版と着ローラの接触圧は一定とする
ことができる。As a result, even when the plate cylinder twists, the stopper moves in the same way as the plate cylinder, so the forming roller also follows through the stopper, and the contact pressure between the plate and the forming roller can always be kept constant.
一方交換胴形の輪転機では、版の大きさや、位置が、そ

ローラの位置や着ローラレバーの角度が異なり、固定胴
形と同じ様に交換側形てヒネリへの追随を行なっても、
そのサイズ毎の調整を行なわなければならず、そのため
の構成は複雑となり、かつその作用は極めてやっかいで
あった。On the other hand, in an exchangeable cylinder type rotary press, the size and position of the plate differ depending on the size, so when the plate cylinder is replaced, the position of the forming roller and the angle of the forming roller lever will naturally change, just like with a fixed cylinder type. Even if the exchange side shape follows the twist,
Adjustments had to be made for each size, making the configuration complex and its operation extremely troublesome.
本発明は上記のことにかんがみなされたちので、異なる

刷機における着ローラ装置を提供することを目的とする
ものである。Since the present invention has been made in consideration of the above, it is possible to automatically perform the movement of the forming roller to follow the twisting of each plate cylinder even in each plate cylinder in a different exchangeable cylinder unit, and the device is equipped with a cam and a stopper. A forming roller device for a rotary printing press with an exchangeable side type, which can be obtained with a simple configuration, and further enables easy adjustment of the contact pressure of the forming roller against the plate cylinder when replacing the exchangeable cylinder unit, etc. The purpose is to provide the following.

触している着ローラはこのヒネリに追随して移動し、接
触圧か変わることなく版胴に接触される。By eccentrically rotating one of the bearing devices that supports both ends of the plate cylinder, twist is applied to the plate cylinder, and the forming roller in contact with the plate cylinder moves to follow this twist, increasing the contact pressure. It is in contact with the plate cylinder without changing.
