Definitions

  • the invention relates to a method and a device for regulating the contact pressure in a contact roller that is rotatably mounted and cooperates with a rotary driven material guide roller.
  • the invention further relates to a piston-cylinder unit for regulating the contact pressure in a cooperating with a rotary driven goods guide roller
  • thermoplastic film e.g. Air pockets between the fabric guide roller and the pressure roller are avoided by pressing a pressure roller equipped with a rubberized roller jacket on the linear run-up of the film onto the fabric guide roller.
  • the pressing must take place across the width of the film, namely linearly at the run-up of the goods guide roller and with an almost constant pressure level of the pressure roller.
  • the deflection of the roller increases with increasing bearing distance and, on the other hand, the applied pressing force leads to the linear contact of the rollers being lost across the width of the goods goes, ie the rollers only have contact in the area of their ends, while no contact pressure is achieved in the middle area.
  • a further increase in the contact pressure does not lead to a better result, but rather to an increase in the gap between the rollers.
  • Peripheral speed is slightly higher than in the non-domed area.
  • negative Influences in particular on the surface and the structure of a thermoplastic film in particular, are not thereby excluded.
  • Piston of the piston-cylinder unit be about 160 mm.

  • a force of the stationary pressing force F M of the pressing roller opposed to a stationary, pressurizable pressure body is effective to obtain the desired pressing force F ⁇ .
  • the pressure body is a pressure cushion known per se, which is connected to the control or regulating device in which the size of the contact pressure F ⁇ is stored as the desired value.
  • the pressure body is further connected to means known per se, which exert a force opposing the actual contact pressure F A ⁇ via a corresponding pressurization in order to obtain the desired contact pressure F M.
  • At least one piston-cylinder unit is provided, in particular for regulating the contact pressure in a contact roller interacting with a rotary driven material guide roller, an elastic body which can be pressurized being arranged between the piston-side cylinder cover of the working cylinder and its articulation point of the cylinder opposite the piston rod articulation point exerts a force opposing the actual contact pressure F A ⁇ of the contact roller to maintain the target contact pressure F A2 on the piston-cylinder unit.

  • Figure 2 shows a piston-cylinder unit with an integral pressure pad as an alternative solution to the device shown in Figure 1.
  • the schematically illustrated device 1 of a treatment plant for a web of goods 2 comprises a rotary driven goods guide roller 3 and a pressure roller 5 which can be brought into and out of contact with the goods guide roller 3 by means of a piston-cylinder unit 4 mounted pivot lever 6 rotatably held.
  • the piston rod 9 of the piston-cylinder unit 4 is articulated on a bracket 8 at each roller-side end of the pivoting lever.
  • the end of the piston-cylinder unit facing away from the piston rod 9 is arranged in a machine-fixed manner.
  • the other free end of the pivot lever 6 is operatively connected to a fixed pressure body 10, which is a pressure cushion known per se, via a push rod 12 preferably mounted in a slide bearing 11.

If the pressure force F A1 obtained thereby or the actual contact pressure P1 built up in the cylinder is greater than the target pressure force FA ⁇ or greater than the target pressure pressure P2 which is generated in FIG the pressure applied to the pressure body 10 is a counterforce to the actual contact pressure F A ⁇ . This counterforce is then effective on the free end of the pivot lever 6 via the push rod 12, whereby the desired target contact force F A2 is established.

Abstract

L'invention vise à empêcher le dépassement d'une force d'application prescrite prédéfinie d'un cylindre de pression qui peut être appliqué sur un cylindre de guidage de produit au moyen d'au moins un groupe cylindre-piston à fonctionnement pneumatique. A cet effet, le dispositif selon l'invention pour réguler la force d'application du cylindre de pression comprend des leviers pivotants (6) à deux bras, placés à distance l'un de l'autre et tournant autour d'un pivot commun (7). Le cylindre de pression (5) est logé mobile en rotation à une extrémité des leviers pivotants et au moins un groupe cylindre-piston (4) agit sur les leviers pivotants (6) afin de mettre le cylindre de pression (5) en contact avec le cylindre de guidage de produit (3) ou d'empêcher ce contact. Une force, opposée à la force d'application du cylindre de pression (5), d'un corps de pression stationnaire (10) pouvant être mis sous pression agit sur l'autre extrémité du levier pivotant (6) pour limiter l'intensité de la force d'application.
