Definitions

  • a pneumatic pressure system for the Doctor blade component is a pneumatically pressurizable Pressure hose held on the doctor blade and presses the Squeegee component against the work surface.
  • the pressure hose can Irregularities, especially those irregularities that occur on the Deflection of the doctor blade base is based, partially compensate. It has however, it has been shown in practice that such a pneumatic hose is a allows certain uniformity of the dash cross profile, but this is insufficient.
  • the pneumatic hose especially guides due to its Material inhomogeneity and its comparatively rough Manufacturing tolerances to new irregularities with relatively large ones tip-shaped deviations.
  • the tub-like character of the Dash cross profile cannot be completely compensated.
  • the compensation system acting on the doctor blade carrier is the high one Effort both for the components of the compensation system as well must be operated for its control. So first of all Straightness deviations of the doctor blade carrier can be measured. This is usually done using a laser measurement, which is very is expensive. The measurement results obtained by laser technology must then be converted into control signals that the temperature of the in the Circulations of water circulating water or the pressure in the Regulate pressure hoses. This is comparatively complicated Control algorithms required. Finally, the component expense for the control loop with the water circuits or the pressure hoses considerably.
  • the invention is therefore based on the technical problem of a Setup of the type mentioned at the beginning with less effort compensate for undesired deformations of the doctor blade carrier and an im to be able to achieve a substantially uniform dash cross profile.
  • the invention provides that the in the force flow path between the squeegee carrier and the squeegee component arranged part of the compensation device is designed to Deformations of the doctor blade carrier relative to the work surface in this way compensate for that between the squeegee surface and the work surface effective pressing force essentially unaffected by these Deformations.
  • the invention represents a departure from that in the prior art prevailing principle, the undesirable deformations of the To compensate for the squeegee carrier by targeted counter-deformation.
  • she makes take advantage of the knowledge that for a uniform line cross profile like also for a uniform line length profile (i.e. the profile of the line thickness in the longitudinal or moving direction of the work surface] a constant Pressing force between the doctor surface and the work surface is essential.

  • a piston-cylinder arrangement provides a structurally simple design of a compensation unit represents approximately constant size pressure area.
  • the piston can basically be a sliding seal in the Cylinder housing guided piston, the piston immediately the Pressure chamber limited and with its pressure chamber facing Piston side forms the pressure area. Because of the lesser However, friction loss is preferred in a solution where the power unit one held all around on the edge of the cylinder housing Compensation membrane, which in the cavity, the pressure chamber fluid-tight compartment and with its side facing the pressure chamber Pressure area forms. The at least one piston then stands up the side of the membrane facing away from the pressure chamber with this one force-transmitting system contact.
  • the membrane solution is so far advantageous as the membrane for hermetic sealing of the Pressure chamber ensures that it is maintenance-free and does not require any lubrication. Furthermore, the stick-slip effect known from pistons with a sliding seal avoided. Finally, the membrane solution is characterized by a low wear and a long service life.
  • the cylinder housing is expediently attached to the doctor carrier be formed, wherein the at least one piston for common Displacement movement is coupled to the doctor blade component. Since the Doctor blade component usually wears out comparatively quickly and must be replaced accordingly frequently, it is appropriate to To produce pistons as a separate component from the doctor blade component, which is mechanically detachably coupled to the doctor blade component, is in particular in contact with the doctor blade component. The Squeegee component can then be replaced without the Need to replace pistons.
  • a particularly smooth and low-loss compensation unit results itself when the power transmission piston on the cylinder housing in is essentially unguided, but in a position-stabilizing, in particular positive connection with the doctor blade component. Any Frictional losses that occur between the piston and the cylinder housing mechanical frictional contact could be avoided.

  • the pressure in the Pressure chamber is the same at all points. Therefore acts on the membrane Every point of the pressure chamber the same pressure, which is why over the entire Width of the working area the same pressure between the squeegee area and the work surface is created.
  • a targeted cross-profiling of the Line width of the applied medium by a targeted local Change the pressure between the squeegee surface and the work surface could be achieved is not by pressure variations in the pressure chamber possible.
  • a longitudinal profile is of course possible by the Pressure in the pressure chamber, for example, depending on the measured Line width of a previously painted part of the work surface in the desired Way is varied.
  • Another preferred development of the invention provides that along The width of the work surface spreads several pressure chambers with one each in particular circular compensation membrane are provided and that at least one piston is in contact with each compensation membrane stands. If in this training at least in part of the Pressure chambers, especially in all pressure chambers, independently a predetermined pressure can be set from each other, is also a Cross-profiling of the line thickness of the medium possible.

  • the squeegee 17 is subject to operational deformations, which are mainly caused by Temperature differences between its the work surface 3 facing Side and its side facing away from the work surface 3 become. The cause of these temperature differences is that in a Coating in a plant for the production of paper or cardboard webs coating medium to be applied is relatively warm and so that of the work surface 3 facing side of the doctor bar 17 of the coating medium radiated heat is exposed and warms up more than that Back of the doctor bar 17. The result is that the doctor bar 17 bends towards the work surface 3 in its longitudinal center.
