Definitions

  • the invention relates to a device for applying a uniformly thin over the working width, laminar flowing on a continuously advancing web liquid film - preferably large working width - and control of this device by a pumped by a timely activated pump liquid, with a diesstechniksverteil excited and a at this provided via a supply line connected to the pump liquid distribution space and an associated, adjoining the liquid distribution space, aligned at an angle to the horizontal guide surface, from the lower edge of the effluent liquid film runs on the web.
  • a device of this kind is e.g. by EP-A-0 472 050 or WO 2004/048671.
  • a uniform order of the dyeing liquor in any desired amount over the working width of the web is ensured with the construction of this device. It is a solution to look for how with this device, a quick change of the dyeing liquor can be achieved with unchanged uniformly advancing web, without too much web length is lost unclean or undyed.
  • the invention has for its object to find a device with which a quick color change is made possible without pivotingthesei whatsoever.
  • the solution found the task is that for which a Vorbewegte web two of these application devices arranged with one pump in the same orientation at a distance one behind the other and the web are assigned, only one of these devices as intended the associated pump is supplied with the application liquid, wherein the pumps of the two devices for conveying the respective application liquid are controlled such that the actual distance between the application devices with respect to the temporally activated order activity is optimized in terms of a shortened empty distance of the web.
  • a liquid collecting tray provided with a drain in both application devices below and above the material web, with the respective liquid collecting tray being arranged in a stationary manner is and whose the lower edge of the guide surface of the application device associated wall is displaced back relative to the plane of the outflowing liquid film.
  • a liquid deflection rail extending over the working width of the application device is arranged to be movable back and forth. With this liquid deflector rail and the associated drip pan, the end or the beginning can be absolutely exact within seconds of the contract.
  • the draining into the drip tray liquid can be reused or eliminated during flushing by means of appropriate valves in the sewer.
  • the color change is optimized to a few cm web length exactly over the web width possible.
  • the two identically formed liquid application devices A and B according to FIG. 1 each consist of an angle-shaped beam 1, whose 90 ° comprehensive overflow weir 2 is oriented upwards.
  • the one obliquely upwards to the overflow weir 2 extending leg is the stowage wall 3, which is followed by the overflow weir 2, the guide surface 4.
  • the liquid film or layer to be applied flows uniformly over this guide surface and flows onto the material web 6 after the lower edge 5 of the guide surface 4 has expired.
  • this liquid storage space 8 is initially limited by the stowage wall 3 and the spaced-apart, parallel counter-stowing wall 9 of the liquid-distributing body.
  • the construction of the storage and remplisstechniksverteilhow may also be constructed differently and is part of the content of the invention, the only essential is that the mecanicschmanende liquid over the guide surface 4 runs and runs from the edge 5 on the web 6.
  • the liquid inlet region is arranged. It consists of a variety of cross through the sosstechniksverteil stresses 7 extending bores, which then have at the lower end of the liquid storage space 9, the liquid inlet openings.
  • a liquid distribution device 10 is arranged, as also described in EP-A-0 472 050. To her the application liquid passes evenly over the working width on the lines 11 of the only indicated, upstream distribution system 12 with a feed pump, not shown.
  • a liquid collecting tray 15 is arranged below the bar-shaped application head 1 with the guide surface 4 and above the web 6 with laterally arranged outside the web width discharge channel 16, in the z. B. the previous color fleet is redirected.
  • the edge 5 'of the liquid collecting trough 15 assigned to the outflow edge 5 ends in front of the level 1 'of the running off of the guide surface 4 liquid film to ensure there unimpeded order. Securing the web 6 of unwanted application causes a over the entire working width extending remplisstechniksumschiene 17 which surrounds the flow edge 5 of the guide surface 4 in accordance with the device B in its cross section.
  • the lower wall 18 of the remplissyersumschiene 17 extends in the case of their function, ie in the advanced state according to B, with its run-off edge 18 'above the drip pan 15, so that over the guide surface 4 finally still running residual paint liquid collected and according to arrow in the tub 15th can be transported.
  • the liquid deflecting rail 17 is fastened to a carrier 19 extending over the working width of the application device and can be moved back and forth by means of pneumatically actuated cylinders 20.
  • a retracted rail 21 along the deflecting rail 17 is stationary when retracted rail 17 according to the device A, so possibly one of the run-off edge 18 'unintentionally dripping on the device A residual liquor for the web 6 can be collected harmless.
  • a catching rail can also be fastened underneath the lower wall 18 of the liquid deflecting rail 17 and thus be movable back and forth.
  • the two application devices A and B are coordinated so controlled by means of electrical impulses for the pumps both applicators and the moving means such as pneumatic cylinder diesstechniksumschschienen taking into account the advance speed of the web, that the not wetted by one of the different contract liquid range of the web is only a few cm.
  • the adjacent application device has a temporally stopped application activity due to the advanced liquid deflection rail 17 (B). It can be prepared for future job performance by flushing and removing the flushing fluid by means of the advanced fluid deflector bar and associated fluid catchment pan, and timely and complete supply of the following application fluid.
