更にダンサローラ 5に対し、 ダンサローラが中立位置になる よ う機械的に保持するダンサロ—ラス ト ッパ— 10をダンサロ 一 ラ 5に設け、 印刷ュニッ ト 6の胴の着脱を検知する胴着脱検知 器 11を印刷ュニッ ト 6に設け、 ダンサロ 一ラス ト ツバ一 10の O N— O F Fを制御するダンサロ一ラス ト ッパー制御装置 12を設 けてある。  In addition, a dancer roller stopper 10 that mechanically holds the dancer roller 5 at the neutral position with respect to the dancer roller 5 is provided on the dancer roller 5, and a cylinder attachment / detachment detector that detects attachment / detachment of the cylinder of the print unit 6. 11 is provided on the printing unit 6, and a dancer-stopper control device 12 for controlling ON-OFF of the dancer-last stopper 10 is provided.
このよ うな装置において、 リ ールスタ ン ド 1に装着された走 行紙 2は各ガイ ドロ一ラ 3に案内されて、 イ ンフィ ー ドドラグ 口一ラ 4に至り、 更にイ ンフィ ードドラグロ一ラ 4を ?1り、 ダ ンサローラ 5を経由して印刷ュニッ ト 6に導かれる。  In such a device, the running paper 2 attached to the reel stand 1 is guided to each guide roller 3 to reach the infeed drag opening roller 4 and further to the infeed drag roller 4. Then, it is guided to the printing unit 6 via the dancer roller 5.
印刷ュニッ ト 6の胴入れ前には、 胴の脱信号を胴着脱検知器 11が検知し、 この脱信号により、 ダンサローラス ト ッパー制御 装置 12、 ダンサロ—ラス ト ッパー 10を作動させて、 ダンサロ一 ラ 5を中立位置に保持する。 Before the printing unit 6 is inserted into the cylinder, the cylinder removal signal is detected by the cylinder attachment / detachment detector 11, and the release signal is used to control the dancer roller stopper. Operate the device 12, the dancer stopper 10, and hold the dancer roller 5 in the neutral position.
次に印刷ュニッ ト 6が胴入れされると、 胴着脱検知器 11によ り胴の着信号をダンサロ—ラス ト ッパ—制御装置 12へ供給し、 ダンサロ一ラス ト ッパー 10の固定を解除する。  Next, when the printing unit 6 is inserted into the cylinder, the cylinder attachment / detachment detector 11 supplies a cylinder arrival signal to the dancer-last stopper control device 12 to release the fixing of the dancer-last stopper 10. I do.
なお、 胴入れ前及び後ともダンサローラ位置検出器 7、 変速 比制御装置 8、 変速機 9によりダンサロ—ラ 5が常に中立位置 となるよ うにイ ンフィ ードドラグロ—ラ 4の変速比制御を行な 以上説明したよ う 、 本発明はダンサローラ位置検出器と ド ラグ口—ラ変速機と変速比制御装置とよりなるダンサローラ方 式イ ンフィ ード張力制御装置を備えた輪転印刷機において、 ダ ンサ口一ラス ト ッパーと、 印刷ュニッ トの胴着脱検知器と、 月同 着脱検知器の着信号によりスト ツ —の解除をまた該胴着脱検 知器の脱信号を受けるとス ト ッパーをダンサロ一ラにかけて、 上記ダンサローラの位置制御を行う ダンサ π —ラス ト ッパー制 御装置を備えて、 前記の作用が行なわれるため、 胴入れと同時 にダンサローラの負荷が走行紙に伝わり、 しかも急激なダンサ 口ーラの位置の変動がないため刷り出し時の走行紙のテンショ ンが安定し、 刷り出し時の走行紙の蛇行、 あるいは断裁狂い等. の障害が鍪減し、 刷り出し時の損紙を大幅に減少できる効果が ある。  Note that the gear ratio control of the infeed drag roller 4 is performed by the dancer roller position detector 7, the gear ratio control device 8, and the transmission 9 so that the dancer roller 5 is always at the neutral position before and after the cylinder insertion. As described above, the present invention relates to a rotary printing press provided with a dancer roller type inflation tension control device including a dancer roller position detector, a drag port transmission, and a gear ratio control device. The stopper is released by the arrival signal of the cylinder, detachment detector of the printing unit, and the monthly detachment detector, and the stopper is released by the dancer controller when the cylinder detachment detector receives a signal from the cylinder attachment / detachment detector. And a dancer π—last stopper control device for controlling the position of the dancer roller during the period above, so that the above-mentioned action is performed, so that the load of the dancer roller is transmitted to the running paper at the same time as the cylinder is inserted. In addition, since there is no sudden change in the position of the dancer opening roller, the tension of the traveling paper at the time of printing is stabilized, and the obstacles such as meandering of the traveling paper at the time of printing or cutting errors are reduced. This has the effect of greatly reducing the number of waste sheets during printing.
