Definitions

  • GB-A-2 053 856 discloses a web tension controller for a web running from a supply roll, in which a roller, which is wrapped by the web deflected by 180 ° from the web running plane, perpendicular to the web running plane through the web train against a predetermined one Force is moved up and down. Depending on the roller position, which changes with the web tension, a brake on the axis of the supply roll is activated in order to achieve a constant tension of the web regardless of the diameter of the stock roll and / or the unwinding speed of the web. A correction of lateral path deviations is not possible with this known path controller.
  • the invention is based on the task of enabling a web guider of the type mentioned at the outset to also regulate lateral web deviations in addition to precisely regulating the web tension in the running web.
  • the brake roller exerts a more or less large braking force on the web of material that wraps around the brake roller, thereby influencing the web tension.
  • the web tension is detected on the measuring roller and in turn serves to actuate the braking device via the controller, so that there is a closed control loop for the size of the web tension.
  • the desired web train can be preselected in the controller using the setpoint adjuster. Since this web tension control only requires the wrapping of the brake roller and the measuring roller, the web tension control according to the invention for the web is very gentle on the edges and the surface, so that even sensitive webs can be controlled with the web guider according to the invention.
  • the measuring roller is elastically resiliently mounted in a force measurement bearing transverse to the roller axis and in this direction the transducers absorb the force resulting from the web train on the measuring roller axis.
  • the transducers are expediently arranged strain gauges on elastic bearing pieces of the measuring roller bearings.
  • the web guider shown in the drawing for a web generally denoted by 1 has guide rollers 2.1, 2.2 which can be freely rotated about parallel axes 3 and over whose lateral surface the web runs.
  • the guide rollers are arranged in a rotating frame 4 which is rotatably mounted on a fixed frame 5 about an imaginary axis 6 and can be rotated about this axis 6 by means of a servomotor 7.
  • the servomotor 7 is depending on the lateral web offset behind the second in the rotating frame 4 guide roller 2.2 by means of one on the lateral course of the web edge or a guide line on the Warehouse responsive storage sensor 8, in the exemplary embodiment, an opto-electrical sensor from an infrared transmitter 8.1 and infrared receiver 8.2 controlled.
  • the rotating frame 4 is mounted on the fixed frame 5 by means of arch guides 4 ', not shown in detail, as described in detail in DE 31 25 852 C1, for example.
  • At least one further deflecting roller 9 with a fixed axis of rotation is arranged in front of and behind the first or last guide roller 2.1, 2.2 of the rotating frame 4.
  • the deflecting rollers 9 therefore do not take part in the adjusting movements of the rotating frame 4. They deflect the web 1 over the guide rollers 2.1, 2.2 of the rotating frame 4 in a direction perpendicular to the guide plane 10 between the two guide rollers.
  • the output signals of the position sensor 8 are converted into control commands for the servomotor 7 of the rotating frame 4 in a known and therefore not shown and explained manner.
  • a brake roller 11 is provided in the rotating frame 4 between the guide rollers 2.1, 2.2 with these guide rollers parallel to the axis and outside of their guide plane 10, which is wrapped around and dragged by the web.
  • the brake roller 11 has a brake device 12 actuated by an actuator, so that depending on the Brake roller 11 braking torque exerted by the braking device 12 of the web train in which the web 1 dragging the brake roller 11 can be influenced.
  • a force measuring device which determines the web train, the measured value signals of which control the actuator of the braking device 12 via a controller 13 with setpoint adjustment.
  • the measured value signals of the measured value sensor 15 are fed to a measuring amplifier 17 with a digital display, to which a regulator unit 18 is connected, which is guided by a setpoint adjuster 19.
  • the controller unit 18 contains amplifier, summing and delay elements and works with its output on the signal converter 16, which is connected with its pneumatic part to a pneumatic supply unit 20 and with its output 21 to the pneumatically actuated disc brake 12.
