Definitions

  • the invention relates to a device for preventing damage to production facilities with rotating cylinders, preferably rubber cylinders of web-fed rotary printing presses, according to the preamble of claim 1.
  • Such a generic device is such. B. become known from DE-PS 5 58 071.
  • a disadvantage of this device is that the conveying speed of the torn paper web is also dependent on the inertial masses of the two rollers involved. Particularly when used after an offset printing unit, it cannot be avoided that the web winds up on the blanket cylinder and printing unit damage can occur.
  • the invention has for its object to provide a device for preventing damage due to web breaks in production units, with which it is possible in a web break between two rotating clamping locations for the web, preferably two pairs of rubber cylinders of two printing units of an offset web-fed rotary printing press, the web transport the subsequent, rotating Clamping location, e.g. B. to design the first pair of rubber cylinders such that winding of the web onto the re-feeding clamping location is avoided.
  • the cylinders 4, 6 are preferably rubber cylinders of the web-fed rotary printing press.
  • Between the two clamping locations 2, 3 there is a web guide roller 9, which has the function of a pull-out roller and z. B. is mounted on a shaft 11. Through this web guide roller 9 and elastic rollers 12 set thereon with a defined force, further clamping locations 13 of the web 1 are formed. At least two, in the example shown three, of these rollers 12 are arranged on the web guide roller 9. Alternatively, a roller can be used instead of the rollers 12.
  • rollers 12 The function of the rollers 12 is described in more detail below using the example of a roller 12.
  • the roller 12 is rotatably attached to a lever 14.
  • This lever 14 is pivotable about a spindle 16 which runs parallel to the web guide roller 9 and is arranged fixed to the frame axially displaceable.
  • the lever 14 can be pivoted away from the web guide roller 9, so that a gap is formed between the roller 12 and web guide roller 9, for. B. to facilitate the retraction of the web 1.
  • the web guide roller 9 can execute a rotating movement on the shaft 11.
  • This shaft 11 is in turn rotatably supported in the frames 18, 19.
  • the shaft 11 is driven by a drive which, in the exemplary embodiment, is formed from a torque-switched clutch 21, an intermediate wheel 22, a cylinder drive wheel 23 and a drive wheel 25.
  • the web guide roller 9 is caused by frictional engagement of the clutch 24 the shaft 11 at a lower speed than that of the web guide roller 9 temporarily driven in the web direction.
  • the speed difference between the shaft 11 and the web guide roller 9 can be in the range from 0.2% to 1.5% and is preset for a selected value. This ensures that the re-conveyed end of the torn web 1 is transported through the web guide roller 9 and pair of cylinders 7, 8 in the direction of the clamping location 13 until the cylinders 7, 8 have come to a standstill.
  • the torque-switched coupling 21 releases the connection between the shaft 11 and the power input z when a defined torque is exceeded.
  • the clutch 21 is a non-positive clutch z. B. disc friction clutch.
  • Fig. 3 shows an embodiment of a directional clutch 24 in the form of a pinch roller freewheel.
  • the driving part 26 which is in the form of a driver star, moves at a lower speed than the driven ring 27 and thus as the web guide roller 9, the pinch rollers 28 are pressed in the direction of the springs 29. If the speed of the driving part 26 is greater than that of the driven ring 27, a wedge surface 31 and the driven ring 27 in connection with the pinch rollers 28 create a frictional connection between the shaft 11 and Web guide roller 9 generated. This is the case when the web speed at the clamping location 13 is lower than at the clamping location 2.
  • the web guide roller 9 can, for example, be mounted on the frames 18, 19 and the coupling 24 can be fastened outside the frame 19 to a shaft end rigidly connected to the web guide roller 9.
  • the drive 22, 23, 25 shown could also be carried out by a speed-controlled drive (electrical, pneumatic, hydraulic), which drives its setpoint z. B. from a coupled with one of the cylinders 7, 8 speed sensor z. B. receives encoder.
  • a speed-controlled drive electrical, pneumatic, hydraulic
