Definitions

  • the invention relates to a method and a device for applying a cooperating with a rotationally driven goods guide roller, rotatably mounted pressure roller.
  • thermoplastic film e.g. Air pockets between the fabric guide roller and the pressure roller can be avoided by pressing on the line-shaped casserole of the film on the guide roller equipped with a rubberized roll shell pressure roller.
  • the pressing must be done across the width of the film, namely on the casserole of the cloth guide roller linear and with a nearly constant pressure level of the pressure roller.
  • the deflection of the roller increases and on the other hand, the applied contact force causes the linear contact of the rollers over the fabric width lost goes, that is the rollers have contact only in the region of their ends, while in the central region no contact force is achieved.
  • a further increase in the contact pressure leads to no better result, rather still to an increase in the gap between the rollers.
  • the object of the present invention is therefore to provide a device with which a simultaneous contact contact is ensured on the entire roll width when applying a pressure roller to a goods guide roller, wherein a predetermined desired contact pressure between the guide roller and the pressure roller neither during the application process, is exceeded during further operation.
  • a method is provided, according to which a first, double-acting piston-cylinder unit, the pressure roller in the direction of the goods guide roller shifts to the end stop of the first piston-cylinder unit.
  • the end stop of the first piston-cylinder unit is adjusted so that the pressure roller is axially parallel to the goods guide roller with a predetermined residual stroke.
  • a second piston-cylinder unit At the end stop of the piston of the first piston-cylinder unit acts a second piston-cylinder unit, which is operatively connected via a lever with the first piston-cylinder unit, advantageously as a shock absorber.
  • the pressure P1 for acting on the first piston-cylinder unit is set so high that the applied cylinder force of the first piston-cylinder unit is greater than the force of the acting via the lever second piston-cylinder unit.
  • the first piston-cylinder unit thus acts as a rigid connection during the following process steps.
  • the second piston-cylinder unit is pressurized P2.
  • the second piston-cylinder unit now performs, via the force-enhancing lever and acting on the first piston-cylinder unit, the remaining stroke.
  • the axis parallelism is maintained. This results in a simultaneous contact over the entire roll width.
  • the pressure P2 is adjusted so that the desired contact pressure between the rollers results.
  • the lever with a power amplifying ratio allows a correspondingly small dimensions of the second piston-cylinder unit with correspondingly small cylinder volume and small frictional forces of the gaskets. This results in two advantages.
  • the residual stroke is performed on both lateral bearings of the pressure roller almost simultaneously and at a uniform speed, because the cylinder volume is small and thus the reaction time of the piston-cylinder unit is short.
  • the axis parallelism is maintained during the rest of the stroke and the almost simultaneous touch contact over the entire roll width is guaranteed. This avoids an adverse effect on the quality of the goods that would occur in the case of one-sided contact.
  • the solution according to the invention advantageously achieves a narrow, nearly constant contact force of a pressure roller on a guide roller over the length of the rollers while avoiding trapped air between the roller surface and the web, and further experiences the surface of the guided over the guide roller product no qualitative impairments.
  • the second piston-cylinder unit retracts and thus acts at the end stop of the first piston-cylinder unit advantageous as a damper. After reaching the end stop of the first piston-cylinder unit, the second piston-cylinder unit is extended. Thereafter, the device is ready to start again for the next startup.
  • a device for carrying out the method according to claim 4, a device is provided, according to which a pressure roller is rotatably mounted in spaced apart support arms, which are rigidly connected to the guide carriage at least one fixed linear guide, each arm at least one first piston-cylinder unit effective is.
  • the first piston-cylinder unit is pressurized by a pressure source via a first pressure regulating valve, a first control valve and compressed air via compressed lines.
  • the first piston-cylinder unit establishes an operative connection between the support arms and a lever pivotable about an installation-fixed pivot point, the free end of which is operatively connected to the piston rod of a second piston-cylinder unit.
  • a Cylinder of the second piston-cylinder unit is operatively connected to a plant-fixed point.
  • the second piston-cylinder unit is pressurized by the pressure source via the first pressure regulating valve, via a second pressure regulating valve, via a second control valve and via pressure lines with compressed air.
  • the first and the second control valve is signal transmitting connected to the electronic control of the system.
  • two position switches at the end positions of the pistons are arranged on the first and on the second piston-cylinder unit, which are signal-transmitting connected to the electronic control of the system.
  • a first double-acting piston-cylinder unit 7 is provided for applying a pressure roller 4 to a rotationally driven goods guide roller 3, which is operatively connected via a lever 9 with a second double-acting piston-cylinder unit 8.
  • the pressure roller 4 is mounted laterally in a support arm 6, which is rigidly connected to the guide carriage 5a of a linear guide 5.
  • a device 1 is shown in each case.
  • the first piston-cylinder unit 7 must be completely retracted. This is signaled to the controller 10 by the position switch 7a via the signal line 7c.
  • the second piston-cylinder unit 8 must be fully extended. This is signaled to the controller by the position switch 8b via the signal line 8d.
  • the controller 10 sends a signal via the signal line 11 b to a first control valve 11.
  • the control valve 11 is actuated and the first piston-cylinder unit 7 is supplied via the pressure line 19b with compressed air.
  • the required compressed air flows from the pressure source 15 via the pressure lines 16, 17, 19 and 19b in the first piston-cylinder unit 7.
  • the pressure P1 for acting on the first piston-cylinder unit 7 is set to a first pressure control valve 13.
  • the first piston-cylinder unit 7 extends and shifts the pressure roller 4 in the direction of the goods guide roller 3 to the end stop of the first piston-cylinder unit.
  • the second piston-cylinder unit 8 acts as a shock absorber.
  • the position switch 7b outputs via the control line 7d a signal to the controller 10 as soon as the first piston-cylinder unit 7 is fully extended.
  • the controller 10 then outputs a signal to a second control valve 12 via the control line 12a.
  • the control valve 12 is actuated and a second piston-cylinder unit 8 is supplied via the pressure line 18 a with compressed air.
  • the required compressed air flows from the pressure source 15 via the pressure lines 16, 17, 18 and 18 a in the first piston-cylinder unit 7.
  • the pressure P2 for acting on the second piston-cylinder unit 8 is set to a second pressure control valve 14.
  • the second piston-cylinder unit 8 retracts and moves via the lever 9 and the rigidly extended first piston-cylinder unit 7, the pressure roller 4 in the direction of the goods guide roller 3, to contact exists.
  • the position switch 8a sends the controller 10 via the control line 8c the signal "second piston-cylinder unit retracted". Thus, the operating position of the pressure roller is registered in the controller.
  • the pressure P2 is adjusted so that the desired contact pressure between the rollers results.
  • the pressure P1 is higher than the pressure P2. This ensures that the extended piston-cylinder unit 7 acts like a rigid connection in operation and only the pressure P2 determines the contact pressure between the rollers.
  • the controller 10 receives the signal to drive away the pressure roller 4 from the operator of the system, then the controller sends a signal via the signal line 11a to the control valve 11.
  • the control valve 11 is actuated and compressed air is applied to the first piston-cylinder unit 7, that the piston retracts and the pressure roller 4 moves away from the goods guide roller 3.
  • the second piston-cylinder unit 8 acts as a shock absorber.
  • the position switch 7a outputs via the control line 7c a signal to the controller 10, as soon as the first piston-cylinder unit 7 is fully retracted.
  • the controller 10 then outputs a signal to the second control valve 12 via the control line 12b.
  • the control valve 12 is actuated and the second piston-cylinder unit 8 is pressurized via the pressure line 18b in such a way that the piston extends.
