Definitions

  • the present invention relates to a device for the lateral guidance of a running material web with a pivoting frame pivotable about an off-center pivot axis and a stationary web cantan run-out sensor at a short distance from the deflection roller remote from the pivot axis for obtaining a position deviation signal of the web running from this deflection roller for one on the Swing drive of the swing frame acting control loop.
  • a device for the lateral guidance of a running material web with a pivoting frame pivotable about an off-center pivot axis and a stationary web cantan run-out sensor at a short distance from the deflection roller remote from the pivot axis for obtaining a position deviation signal of the web running from this deflection roller for one on the Swing drive of the swing frame acting control loop.
  • Such a device is known from the article "Basic Techniques for Controlling Web Position" by Sorsen in "Automation", April 1966, p. 105 ff., Fig. 3 (b).
  • Such devices usually have two of the swing frame deflection rollers and only need one short inlet length because the swivel axis is approximately in the Level of the surface line of the deflection roller near the swivel axis runs on which the incoming material web section runs up, so that this with the corrective swivels only experiences a torsion, but not a lateral offset.
  • a complex solution to this task is to a swivel drive on both sides of the swivel frame to be provided and here to effect a lateral offset to attack, and also close to the drain point of both Deflection rollers to provide a stationary outlet sensor.
  • the Swivel drive on the inlet side in the middle Position locked and the associated web edge sensor switched off while the sensor and the rotary actuator the other side of the swing frame the known scheme effect on the outlet side.
  • This solution is not only because of the need for two rotary actuators expensive, but also because simple and advantageous Positioning and management kinematics of the Swing frame cannot be used as they are from DE-PS 26 35 631 or DE-PS 31 25 852 are known.
  • the swivel frame of sliding guide elements so guided that he only moves around a stationary instantaneous pole as a virtual one Can execute swivel axis.
  • the above invention includes the knowledge that in most cases of use in both directions effective devices for lateral material web guidance one of the running directions is the prevailing one and the regulation for this primary direction should be effective that the incoming web section not subject to lateral displacements and whose control process is based on a lateral position signal, which is a fixed station located near the drain point Web edge sensor generated.
  • a lateral one Relocation of the incoming rail section accepted be, taking yourself to the lateral web guide for this case can operate a controller like it known per se from US 3,411,683 for a running direction is.
  • a controller like it known per se from US 3,411,683 for a running direction.
  • Swivel axis swiveling swivel frame application and the material web runs on the deflection roller remote from the swivel axis on. Your side position is indicated by one with the Inlet sensor connected to the swivel frame.
  • the object of the present invention is therefore to create a device for lateral guidance of a running Web of material while maintaining a simple and proven mechanical design and well-known control quality in one direction and in the other Direction of travel with satisfactory result of the web guiding can be operated.
  • the inlet sensor that is effective in reverse operation is in the simplest training rigid on the swivel frame attached and thus records the changes in the situation the monitored web edge relative to the distance from the swivel axis Side of the swing frame.
  • a hydraulic one or electrical tracking can be used.
  • a virtual connection is also possible, however the web edge sensor is fixed, but be Signal from a signal for the lateral position of the pivot axis distant Side of the swing frame overlaid in the way is that a signal for only the relative changes mentioned is won.
  • the swing frame instead of two deflection rollers also built with only one deflection roller can be, then instead of the swivel axis and deflection roller remote from the swivel axis, the surface lines of the a deflection roller are to be considered, on which the material web runs up or down, i.e. close to the swivel axis and a surface line distant from the swivel axis.
  • the swivel frame can be used instead of two to increase the frictional engagement also three or more deflection rollers exhibit.
  • a swivel frame 8 guided in this way and stored so that it can perform swiveling movements, whose axis 6 extends off-center, approximately in the Level of the section running in the forward mode (arrow V) the material web 12.
  • the swivel drive 9 is indicated as a hydraulic cylinder.
  • Two deflecting rollers 7 and 5 are mounted in the swivel frame 8 and the material web 12 rotates in front of and behind the Deflection rollers of the swivel frame fixed rollers 11 and 4. In forward operation with the direction of travel V is 11 the fixed inlet roller and 4 the fixed one Outlet roller.
  • a web edge sensor 1 attached, which is only in the forward mode is active, i.e. if the section of material monitored by him is the discontinued section, and the therefore represents a leak sensor 1.
  • a web edge sensor 2 is located on a carrier 3 Swing frame 8 held so that it is close to the Fixed roller 4 is located. This sensor is only in reverse operation (Arrow R) active and then monitors the incoming Section of the material web, which is why it is called Inlet sensor 2 is referred to.
  • Arrow R reverse operation
  • the outlet sensor 1 is switched off in reverse operation and the incoming material web section monitoring inlet sensor 2 switched on due to its mechanical connection with the swivel frame 8 whose lateral movements join in and occur in the inlet Lateral deviations recorded before the Reach swing frame 8.
  • the drive 9 becomes like this controlled that the inlet sensor 2 and thus the run-up point on the deflection roller 5 distant from the swivel axis Changes in position of the web edge follows, causing the position error is eliminated without success, i.e. the web edge position is checked behind the swing frame 8. So this operating state is one Control.
  • the swivel drive 9 is in the form of a hydraulic cylinder hinted at; however, it can be an electromechanical Drive or other suitable Find the rotary actuator.
  • the sensors themselves can be of any suitable type be, for example, diode line cameras.
