Definitions

  • the invention relates to methods for operating a web-fed printing press according to the preamble of claim 1 or 3.
  • DE 100 27 471 A1 is a web-fed rotary printing machine with a printing material retracting feed train and a drawing the drawing substrate pull train known, the feed train and the draw roller each have their own drive each with a drive control, the draw roller is operated torque-controlled or torque-controlled during the printing.
  • DE 199 18 399 A1 is a method for operating a web press removed, wherein a substrate web is fed with an adjustable speed in the web press and wherein the adjustment of this speed is performed in response to a force acting on the substrate web tensile force.
  • the invention has for its object to provide a method for operating a web-fed printing machine, wherein in the printing material to be printed by the web printing machine, a gentle construction of the web tension is possible and a jerky pulling is avoided to be recovered in the web printing press substrate web.
  • the achievable with the present invention consist in particular that, in particular during startup of the web press, ie at its start in the From the web press to be printed substrate web a gentle construction of the web tension is possible and a jerky pulling is avoided to be recovered in the web press substrate for printing. As a result, a web break and a production disruption associated with a web break can be avoided.
  • a temporal behavior when starting the web press is optimized with respect to the collection of the printing material, ie the speed at which the web press pulls the printing material during its run-up is adapted to the determined web tension in the recovered web.
  • the application of the solution found is particularly advantageous if, as a result of a disturbance which relates to the tensile force acting on the printing material web, at least one bag-shaped sagging section has formed in the web printing press along the printing substrate web, d. H. a section in which the web tension has collapsed in the substrate web to be recovered.
  • a disturbance affecting the train of the printing material web can e.g. B. by a power failure, a shutdown of the web press, a malfunction in the printing material web providing roll changer or by a new setting of the infeed controlling unit or the infeed regulating unit with respect to a target value for acting on the substrate traction.
  • the figure shows a highly simplified purely schematic a web press with a printing material 01 retracting feed unit 02 and the printing material 01 pulling pull roller 03, wherein a controllable or controllable drive 04, z. B. an electric motor 04, the tension roller 03 drives, wherein the motor 04 of the tension roller 03 controlling control unit 06 or a motor 04 of the tension roller 03 regulating control unit 06 is provided, wherein a control unit 07 controls the intake 02 or a control unit 07, the feed train 02 regulates.
  • the tension roller 03 acts z. B.
  • the web press is z. B. as a newspaper printing machine, in particular as a web offset printing machine.
  • the printing material web 01 is preferably formed as a paper web 01.
  • the feeder 02 pulls the substrate web 01 z. B. from a reel changer 09, which holds at least one roll of the printing stock, wherein the feed unit 02 unwinds the printing substrate 01 by the tensile force exerted on them by the prepared in the reel changer 09 role of the printing material.
  • the tension roller 03 is preferably arranged in the transport direction of the printing material web 01 according to a printing unit 11 belonging to this web-fed printing press, the printing material web 01 drawn by the draw roller 03 passing through this printing unit 11.
  • the printing unit 11 is z. B. as a multiple pressure points exhibiting printing tower 11 is formed. Downstream of the draw roller 03 in the transport direction of the printing material web 01 is preferably a folding apparatus 12, in which the printed printing material web 01 is separated into individual copies of a printed product.
  • control unit 06 controlling the motor 04 of the tension roller 03 or the control unit 06 controlling the motor 04 of the tension roller 03 detects a measured value MA with respect to a force exerted by this motor 04 acting on the printing substrate 01 as a traction drive torque and this measured value MA the feed unit 02 controlling the control unit 07 or the infeed 02 regulating control unit 07 provides, d. H. leads there. If the motor 04 of the tension roller 03 provides the measurement value MA resulting from the detection of the drive torque acting on the printing material web 01 as a tensile force, this has the advantage that no further sensor system has to be provided for this data acquisition in or on the web press.
  • control unit 06 controlling the motor 04 of the tension roller 03 or the control unit 06 controlling the motor 04 of the tension roller 03 control the measured value MA with respect to the force exerted by the motor 04 on the printing material web 01 acting as traction drive torque of the infeed 02
  • Control unit 07 or the infeed 02 regulating control unit 07 in particular during startup of the web press provides, so in particular the run-up of the web press, d. H. their starting behavior can be controlled or regulated as a function of the measured value MA determined from the detection of the drive torque acting on the printing material web 01 as a tensile force, d. H. the respective peripheral speed of the rotational body involved in the transport of the printing substrate 01, z. B.
  • the feed unit 02 and / or the tension roller 03 before reaching a minimum value for the force exerted by the motor 04 of the tension roller 03, acting on the printing substrate 01 as a tensile drive torque the printing substrate 01 with respect to the otherwise permissible speed reduced speed move in.
  • the printing substrate 01 from the infeed 02 z. B. be drawn with a maximum speed, including a funding of the feed train 02 and / or the tension roller 03 for conveying the printing substrate 01 z. B. be accelerated with respect to their respective rotation of their respective controllable or controllable drive unit to a maximum allowable value.
  • the control unit 07 controlling the intake unit 02 or the control unit 07 regulating the intake unit 02 builds up the web tension in the printing material web 01 to be collected in a steadily increasing manner up to a maximum value.
