Definitions

  • the present invention relates to a rotary printing press starting device provided with a tension control device in a rotary printing press using an infeed tension control device using a dancer roller system.
  • a tension control device for a rotary printing press using a conventional dancer roller type inflation tension control device includes a running paper 2 mounted on a reel stand 1 and an infeed and a drive. The paper is sent to the printing unit 6 through the dancer rollers 5 via the guide rollers 3 while being pulled by the lug opening 4.
  • the position of the dancer roller 5 is detected by the dancer roller position detector 7, and this position signal is transmitted to the speed ratio control device 8, and the position of the dancer roller 5 is always set to the neutral position by the speed ratio control device 8.
  • a signal to increase or decrease the speed of the infeed drag roller 4 is sent to the infeed drag roller transmission 9 so that the speed of the infeed and lag roller 4 is adjusted to adjust the position of the dancer roller 5. Is controlling.
  • the tension of the traveling paper 2 is small. Does not rise. After that, the speed of the rotary printing press reaches a certain value or more due to the rising acceleration, and the tension of the traveling paper 2 reaches a certain value or more when the cylinder is inserted. Then, the tension control system starts to operate normally, the dancer roller 5 rises, and is held at the neutral position.
  • the tension of the traveling paper 2 becomes unstable, and the traveling paper 2 may meander, or may cause an obstacle such as an irregular cutting, and there is a problem that there is a lot of waste paper at the time of printing.
  • an object of the present invention is to provide a rotary cultivation printing press at start-up
  • An object of the present invention is to provide a starting device for a rotary printing press having a function in which a dancer roller always rises and is maintained at a neutral position without causing the tension of the running paper to become unstable (smaller). This object is achieved, according to the invention, by starting a rotary printing press as claimed in claim 1.
  • a further object of the present invention is to provide a rotary printing press provided with a dancer roller type infinity tension control device comprising a dancer roller position detector, a drag roller transmission and a speed ratio control device.
  • the release of the dancer is stopped again by the arrival / reception signal of the cylinder attachment / detachment detector of the last stopper and the printing unit.
  • a stopper is applied to the dancer roller by a signal from the body attachment / detachment detector.
  • FIG. 1 is a side view showing an embodiment of an apparatus for starting a rotary printing press according to the present invention
  • FIG. 2 is a side view showing a conventional example of a rotary printing press.
  • the dancer roller stopper holds the dancer roller in the neutral position before inserting the print unit, releases the dancer roller after the cylinder is inserted, and keeps the dancer roller always in the neutral position. It controls the rotation speed of one wheel.
  • the starting device of the rotary printing press according to the present invention will be described with reference to an embodiment shown in FIG. 1.
  • 1 is a reel stand
  • 2 is a running paper
  • 3 is a guide roller
  • 4 is an infeed drag roller
  • 5 is A dancer roller
  • 6 is a printing unit
  • 7 is a dancer roller position detector
  • 8 is a gear ratio control device
  • 9 is an infeed drag roller transmission.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a dancer ⁇ —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.
  • 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.
