Definitions

  • the invention relates to a method for determining the web tension or the web tension in a printing substrate according to the preamble of claim 1. Furthermore, the invention relates to a device for determining the web tension or the web tension in a printing material according to the preamble of claim. 2
  • a printing material web to be printed is usually taken from a stocking roll held ready in the area of a roll changer, transported for printing by printing units and fed to a folder for further processing.
  • the transport of the printing material web through the web-fed rotary printing machine serve so-called draw rolls as well as so-called web guide rolls.
  • Pull rollers are driven by the same associated drives.
  • Web guiding rollers are not assigned any drives. Rather, web guide rollers are dragged by friction of the printing material web.
  • the web train is a force, wherein a web tension is then determined from the web train when it is divided by the width of the web to be recovered.
  • each position of the transport path of the printing material, for which the web tension or the web must be determined each associated with a device which provides a signal which a conclusion on the prevailing at the respective position web tension or the At the respective position prevailing train allows. If it is therefore necessary, as seen in the transport direction of the printing material at a position downstream of a tension roller and at a position upstream of a tension roller to determine the web tension or the web tension, so each of these two positions is associated with such a device and thus measuring point. This is complicated and expensive.
  • the present invention is based on the problem to provide a novel method and a novel device for determining the web tension or of the web tension in a printing material web.
  • the web tension prevailing at a second position along the transport path of the printing material web or the web tension prevailing at the second position are calculated, namely from the web tension prevailing at the first position or from the web tension prevailing at the first position and from forces acting on the first position at least one driven roller and / or at least one towed roller, which is arranged along the transport path of the printing material between the first position and the second position, enter in the printing material web.
  • the present invention it is proposed for the first time to mathematically determine the web tension prevailing at a position along a transport path of the printing material web or the web train prevailing at this position, based on the web tension or the web tension prevailing at another position along the transport path the other position prevailing Web tension and based on forces that enter at least one driven roller and / or at least one towed roller, which is arranged along the transport path between these two positions in the printing material web.
  • Fig. 1 schematically shows a section of a transport path of a printing substrate 10 by a web-fed rotary printing press, wherein in the section of the transport path shown a driven by a drive 11 roller 12, which is also referred to as a tension roller is positioned.
  • a tension roller which is also referred to as a tension roller is positioned.
  • the tension roller 12 can have a promoting or braking effect and register corresponding forces in the printing material web 10.
  • towed rollers 13 are further arranged, wherein the towed rollers 13 are so-called web guide rollers.
  • the web guide rollers 13 are driven by friction entrained by the printing substrate 10 and also contribute forces in the printing material 10 a.
  • a device 16 is arranged at each of these two positions 14 and 15, each of which supplies a signal which makes it possible to draw conclusions about the web tension prevailing at the respective position 14, 15 or the web tension prevailing at the respective position 14, 15.
  • These devices 16 are in particular measuring rollers.
  • Fig. 2 shows a section of a transport path of a printing material web 20 by a web-fed rotary printing press, wherein in the region of this section again a driven by a drive 21 roller 22 is arranged.
  • the roller 22 is therefore again a draw roller.
  • rollers 23 are arranged along the transport path of the printing material web, which are dragged by friction of the printing material web 10.
  • the rollers 23 are again web guide rollers.
  • Fig. 2 shall be determined for two positions 24, 25 along the transport path of the printing material web through the web-fed rotary printing press the respectively prevailing in the substrate web tension or the prevailing web tension.
  • a device 26 which provides a signal which allows a conclusion about the prevailing at the first position 24 web tension or prevailing at this position 24 web tension.
  • the device 26 is preferably a measuring roller.
  • the device 26 may also be a dancer roller or a dancer roller.
  • the web tension prevailing at the second position, namely at the position 25, of the transport path or the web tension prevailing at the position 25 is calculated according to the invention, namely from the web tension prevailing at the first position 24 or from the web tension prevailing at the position 24 and from the forces which enter the rollers 22, 23 in the printing material, which are arranged along the transport path of the printing material between the two positions 24 and 25.
  • the position for which the web tension or the web tension is determined by calculation, seen in the transport direction of the printing material downstream of the position is arranged, for which the web tension or the web train by means of a device determined by measurement becomes.
  • more than two rollers are positioned between the two positions 24, 25.
  • the web tension or the web tension is calculated for the position 25, taking into account the measured in the position 24 by means of the device 26 web tension or the train and on the basis of the forces which between the two Positions 24, 25 arranged rollers 22, 23 enter into the printing substrate 20.
  • the force introduced by a driven roller or tension roller 22 into the printing material web 20 can be detected via the power consumption of the drive 21 of the draw roller 22.
  • the power consumption of the drive 21 is proportional to the torque at the tension roller 22 and thus proportional to the introduced from the tension roller 22 in the printing material 20 force.
  • the characteristics of the drive 21 the drive ratio between the drive 21 and the tension roller 22 and the diameter of the tension roller 22 can therefore be derived from the tension roller 22 introduced into the printing material 20 force.
  • the torque intrinsic demand of the draw roller 22, which results from bearing friction and possibly coupling losses, is taken into account. This torque demand of the tension roller can be determined either mathematically or metrologically in advance.
  • the forces introduced by the towed web guide rollers 23 into the printing material web 20 are, in particular, forces as a result of the torque intrinsic requirement of the web guide rollers, which results in particular from the bearing friction of the web guide rollers. These can also be determined in advance by calculation or metrology.
