Definitions

  • the invention relates to a metering device according to the preamble of claim 1.
  • a metering device is known from DE-C-28 51 015.
  • Figure 1 the pressure tube pressing the doctor rod is arranged inside the doctor bed.
  • the doctor bed is mounted in a sliding guide of the doctor bed holder.
  • this requires a relatively high level of effort, both in terms of construction and material.
  • the object of the invention is to address a metering device in such a way that a transition between the doctor blade rod and doctor blade is possible in a simple manner, without modification, in particular if a profiled strip and the doctor blade are to be provided with a press hose for pressing the doctor blade.
  • the pressure hose for the doctor rod or the doctor bed in the profile strip, which also carries the tip part at one end for pressing on the doctor blade. This results in an offset line of force between the force of the profile bar, which on the tip part on the Scraper blade acts and the force of the pressure hose, which acts on the doctor bed or on the doctor rod.
  • An angle between these two directions of force is particularly favorable, the line of action of the pressure tube preferably passing exactly through the central axis of the doctor rod and deviating only slightly from the radial of the counter roller passing through the line of contact of the doctor rod with the counter roller.
  • the metering device can preferably be arranged in one of the lower quadrants of the counter roll.
  • FIGS. 1-7 each representing variants in principle in a side view, only doctor blade and press hose and possibly - if illustrated - the profile adjustment device of the coating blade, then including profile strip, are shown in section.
  • a coating device or dosing device is sketched in principle as a whole system.
  • the web of material is guided in the cutout of the metering device or counter roller shown by the counter roller W along the doctor bed 11 which holds the doctor rod 2, which is designed here as a doctor blade rod, and already carries the coating composition.
  • the doctor bed is fixed in a holder or clamp 18, 18 'by means of a slide 17 via a leaf spring 16 holding it.
  • the doctor bed is pressed by means of pressure hose 13 in the direction of the counter roll W, which is held in an extension 14 'of the profile bar 14.
  • the profile bar 14 is in turn slidably mounted in a guide 19.
  • the movement of the web or the counter roller W is indicated by the arrow p, the movement of the profile strip by the double arrow u and the movement of the slide 17 by the double arrow v.
  • the direction of force of the pressure hose 13 extends obliquely to the direction of force of the profile strip including its tip part 15 - which is given by the double arrow u.
  • the tube force is aligned here so that it runs through the center line of the doctor blade rod 2 and deviates only slightly from the radial line drawn on the counter roller W in the line of contact of the doctor blade rod 2.
  • the metering device is preferably pivoted by means of the support arms 71 of the doctor bar 72, which carries the metering device with a swivel radius of at least 500 mm and by means of hydraulic lifting mechanisms 73 (see FIG. 6).
  • the tip part 25 of the profile strip 24 is arranged at a greater distance from the clamping 28 at 28 'and 34 than the pressure hose 23, which in turn is here in an extension 24 'the profile bar 24 is held.
  • the rod holder 21 consists of the doctor bed 22 and the plate-shaped holding part 26 formed integrally therewith. This holding part is offset or cranked with respect to the rear wall 37 of the doctor bed, insofar as it is present in the area of the doctor rod 2. It is offset by at least its own wall thickness so that the tip part 25 of the profile strip 24 does not abut the doctor bed.
  • the angular assignment of the force lines of the press hose 23 and the profile strip 24 or their tip part 25 is given, as in the case of FIG. 1.
  • a sliding guide 29 is provided for the profile strip 24.
  • the doctor bed is fixed here via a clamping lug 34, its holding plate 26 and a further pressure hose 30.
  • the adjustment device for the profile strip 24 is indicated here with the screw 31 and can be designed similarly to US Pat. No. 2,695,004.
  • the arrangement according to FIG. 4 also essentially shows the doctor bed design 41 corresponding to FIG. 3, here with the clamping at 48 and 48 '.
  • the pressure hose 43 for the doctor rod 2 is held in the doctor bed 42. It is pressed on via an extension part 44 'of the profiled strip 44 which has the tip part 45 for the coating blade 5.
  • the coating blade 5 is indicated here, as in FIG. 3, by the dash-dotted line at 5.
  • the offset of the holding plate 46 of the doctor bed is dimensioned sufficiently large so that the front edge of the tip part 45 does not touch the doctor bed.
  • Figure 5 shows the similar again and usual parts like the other figures, in particular the doctor bed 51 according to FIG. 1 with the leaf spring 56 holding it in the clamping 58 and 58 'via pressure hose 57.
  • the leaf spring is clamped in an extension 52 of the doctor bed, which is by means of the extension 60 of the Profile bar 54 held pressure hose 53 is pressed against the web.
  • the guide for the profile part 54 having the tip part 55 for the coating blade 5 is designated 59.
  • the solution chosen here is to make the leaf spring 56 holding the doctor bed quite short, so that the tip part 55 of the profile strip 54 is further away from the clamping 58, 58 'than that Pressure hose 53 and the doctor bed is arranged. This results in a very favorable position of the coating blade 5 on the web pressing profile strip 54 and its tip part 55.
  • the adjustment of the profile strip is similar to that already explained in FIG. 3. However, this is only one embodiment, for example, but it can also be used in the other figures.
  • FIG. 1 An arrangement for the so-called bent-blade driving style is shown in FIG. This allows the advantages that both the pressure hose and the profile strip have to be complemented.
  • the profile bar has the advantage of a better or more precise cross-profile control, while the pressure hose is relatively insensitive to errors in the paper and an uneven ink supply.
  • the main advantage of this arrangement is, however, that the contact pressure can initially be applied in its basic setting by the relatively rigid profile strip 61, while by means of the hose pressure uninfluenced by other, restricting parameters, the final pressing of the blade can be achieved uniformly over the web width or roller length. Overall, this results in a relatively simple, not very complex construction, which is suitable for retrofitting older systems.
  • the arrangement is such that the extension 6 4 of the pressure or profile strip 61 holding the pressure hose 63 is provided in the area of the same which is distant from the clamping area 66 of the coating blade 66 provided with the pressure hose 67.
  • the center plane M of the pressing force of the pressure hose 63 can either run in the direction of a radial plane of the counter-roller W or parallel to such a center plane R at a short distance of at most 8 mm.
  • the distribution of the contact forces between the profile strip 61 and the pressure hose 63 can take place approximately in a ratio of 2: 1 in order to have a sufficiently large control range for the contact pressure of the pressure hose 63, but of course there can also be considerable deviations from this.
