Definitions
- the invention relates to a coating device the corresponding to the preamble of claim 1 Art.
- Such coating devices are used to a thin coating applied to a running web spread evenly.
- "goods web” web-shaped substrates of all types should be understood, e.g. Paper and cardboard webs, nonwovens, woven or others textile webs, plastic or metal foils.
- To the Uniformity of the "stroke” often become very high Requirements. This is especially true in the paper area the case because different across the width of the web Strengths of the coating are reflected in the quality of the Paper and its further processability, in particular makes its printability noticeable. This is made more difficult Uniformity of the coating due to the large width of paper webs of 8 and more meters.
- the invention is therefore based on the object Generic coating device with regard to the improve achievable uniformity of the stroke.
- the support structure supporting the squeegee is thus like a hydraulically internally supported roller formed at which, however, is not the roller or doctor tube turns. But it is an exact influence of the Position of the doctor blade edge relative to that clinging to the roller Railway possible. For example, with the large latitudes of paper webs lead even the slightest Contact pressure of a squeegee edge and especially the dead weight the squeegee and the roller to deviations in shape the roller from a straight cylinder. It happens not even on straightness. Decisive for one uniform coating thickness over the web width optimal active adaptation to the course of the substrate, i.e. generally the course of the support a web through a roller. This is through appropriate Actuation of the hydraulic support device can be brought about.
- a pair of rollers emerges from Wo 82/00165, bei which is the support of a tubular roller, axially seen, is located in the same place as the center of the camp a counter roller.

- the hydraulic support device can be in the Claim 2 described be designed.
- the opposing support devices result a double-sided, vibration-damped support of the Doctor tube, the deflection due to the pressure difference is determined.
- the effective level should be the level of the system pressure be the squeegee when interacting with a Counter roll generally the plane of connection of the axes the counter roll and the doctor tube.
- the squeegee also experiences driving forces through the web, that stress the doctor tube perpendicular to the active plane. Such forces can be designed Claim 3 can be counteracted.
- the fluid pressure medium can be tempered, i.e. heatable or be coolable, so that the squeegee certain temperature can be granted (claim 4).
- the hydraulic support device can in a first Possible version designed according to claim 6 be.
- the feed lines are useful according to claim 10 educated.
- the modulus of elasticity is mostly fixed because both the roller as well as the doctor tube made of steel.
- the area moment of inertia but is due to appropriate design, i.e. Dimensioning the cross sections depending on their radial position, changeable.
- Claim 11 it is possible to change the nip force with an adjustment of the pressure of the fluid Medium, i.e. oil or compressed air, without the gap height at the squeegee edge suffering as a result.
- the one set via an appropriate facility Gap remains over its length or over its extent across the track.
- the feature of claim 12 ensures flawless radial positioning of the doctor tube against the Roller.
- the positioning can be adjusted according to claim 13 be made.
- the thickness of the applied Coating measured continuously and the gap height through a drive controlled and by a closed-loop control a desired value of the thickness automatically be respected. It is not excluded the real one Raki as a separate part on the outer circumference of the Attach doctor blade tube.
- the doctor blade is connected in one piece to the doctor tube, what, for example, by machining the Scope of the doctor tube according to claim 16 can be realized and executed in detail according to claim 17 or 18 can be.
- the coating device designated 100 as a whole in FIG. 1 includes two side roll stands 1,2, in which a roller 3 on its roll neck 3 'in lateral Bearings 4 is mounted, the center planes in the roller axis W vertical planes 5 and 6 are located.
- the Roller 3 is with its pin 3 'on the left in Fig. 1 Side at 3 "laterally above the roller stand 1 and there has a wedge 23 arranged in a groove, the can serve as a drive connection.
- the bearings 4 are in Bearing bodies 7 arranged in a to the roller axis W vertical plane have an approximately square plan (Fig. 2).
- the bearing body 7 lies against an upper one horizontal boundary 8 of a rectangular section of the machine stand 1 or 2, the opposite has a horizontal boundary surface 9.
- On this Boundary surface 9 is a pneumatic pressure element 11, which from below against the bearing body 12 a acts as a whole with 13 designated doctor tube.
- the doctor tube 13 extends across the width of the Material web 10 and beyond into the roll stand 1,2 where it is held in the bearing bodies 12.
- the doctor tube 13 is penetrated lengthwise by a carrier 14, the all-round distance to the inner circumference 15 of the doctor tube 13 leaves and at the ends via ball bearing 16 is mounted on the inner circumference of the doctor tube 13.

- Hose 50 there is a corresponding one on the opposite side Hose 50 arranged, the via a feed line 54 the fluid pressure medium can be filled.
- the hoses 40.50 each take a circumferential angle of about 90 °. The resulting, force acting against the roller 3 results from the pressure difference in the hoses 40.50.
- the doctor tube 13 has a relatively large wall thickness and is on the Roller 3 facing side by from opposite Sides of the connection plane E of the axes of the Roller 3 and the doctor tube 13 perpendicular to this in the same Flat routings 37, 38 flattened in such a way that in between a web 39 remains, which is parallel extends to plane E and squeegee 60 with the squeegee edge 45 forms.
- the millings 37, 38 with the web 39 are on the two opposite sides of the Doctor tube 13 formed symmetrically, so that the doctor tube 13 rotated by 180 ° and operated in both positions can be.
- the course can be the knife edge 45 by appropriate pressurization adjust the hoses 40.50 so that they are the course of the opposite surface line of the roller 3 adapts optimally. If the pressure changes, the remains Get customization. This allows on the web 10, the runs between the roller 3 and the doctor edge 45, produces a particularly uniform coating thickness will.
- FIG. 5 is a modified coating device 200 more schematically shown, in which a roller 3rd cooperates with a non-rotatable doctor tube 113, at which is working with a fluid pressure medium Support device by a part-cylindrical shell Longitudinal chamber 140 is formed.
- the longitudinal chamber 140 will through to both sides of the effective level, i.e. on both sides the axes of the doctor tube 113 and the roller 3 connecting plane E, longitudinal seals attached to the carrier 114 104.105 and at the ends of the work area end cross seals 106, 107 of the doctor tube 113 divided.
- the seals lie on the inner circumference 115 of the doctor tube 113.
- the longitudinal chamber 140 is on the Located side of the doctor blade gap 102 and forms a pressure chamber, which with the inner circumference 115 of the doctor tube 113 uniform force per unit length over the working range supported upwards. This is supposed to be due to the hatching Representation to be indicated.
- the fluid Print medium is in the form of a line 144 Longitudinal bore of the carrier 114 and a connecting bore the right end of the longitudinal chamber 140 in FIG and at the left end of the longitudinal chamber 140 in FIG. 5 line 154 drained again. It can be in the longitudinal chamber 140 by throttling one in line 154 arranged valve 155 maintain a desired pressure will.
- doctor blade 160 It may be necessary to temper the doctor blade 160 generally to heat. This can be done in the way happen that the fluid acting in the longitudinal chamber 140 Pressure medium, usually a hydraulic oil, from a reservoir 120 removed by means of a pump 121 and by a heat exchanger 122 is passed before it over the Line 144 enters the roller. That tempered, mostly heated pressure medium is at the other end of the roller line 154 removed again and thus circulated, maintaining pressure through valve 155 becomes. The heat of the temperature-controlled pressure medium is transferred to the Inner circumference 115 of the doctor tube 113 and in this way the doctor blade 160 transferred.
- Pressure medium usually a hydraulic oil
- Fig. 7 is one with respect to the support device another modified coating device 300 is shown, which partially corresponds to the coating device 200 and of which only the doctor tube 113 is shown.
- FIG. 7 instead of one Longitudinal chamber running across the width of the work area 140 as in the coating device 200 are shown in FIG. 7 many piston-like pistons lined up one behind the other Support elements 240 on the side facing the roller 3 in radial cylindrical recesses 241 in the embodiment Bores of the crosshead 114 performed the with its top 242 against the inner circumference 115 of the Apply doctor tube 113.
- the number can also be larger or smaller.
- the Support elements 240 can be individually, in groups or together via a feed arrangement running in the crosshead 114 243 can be supplied with hydraulic pressure medium.
- the lead arrangement 243 is only schematically shown by a single dashed line is shown. If the Support elements 240 not together with hydraulic fluid are supplied, the supply arrangement consists of a corresponding to the number of groups or support elements 240 Number of individual lines.
- the individual support elements 240 can be acted upon desired support profile can be set, which is not a constant supporting force per Unit of length includes, as in the longitudinal chamber 140 5 is the case.
- a particular advantage of the coating device 300 with the lined up support elements 240 are able to the support area in the width direction of the web adjust their width by outside the web width located support elements 240 can be switched off. This is symbolized in Fig. 7 that the outside of the Material width across four supporting elements connecting lines have not up to the line arrangement Reach 243 as shown at 240 '.
- the support elements 240 are closed cylindrical Pistons, which are supported on the pressure pad, which by the cylinder chamber formed in the recess 241 244 existing print medium is formed.
- the Crosshead 114 bends under the line load of the support elements 240 something down as shown in FIG. 7. Thereby the cylindrical recesses 241 deform somewhat. So there must be some play or with piston rings or other seals worked on the support members 240 will. These seals do not become hermetically sealed be so that some leakage fluid on the support elements 240 exits through the end cross seals 245 axially outwardly sealed support element area itself accumulates and discharged via lines, not shown becomes.
- the temperature control of the doctor blade 160 can also Coating device 300 via a line 144 in one Heat exchanger 122 tempered heat transfer medium the space between the inner circumference 115 of the doctor tube 113 and the carrier 114, as shown in FIG. 7 and 8 is indicated by the dashed lines.
- Fig. 9 is a modified coating device 400 shown, based on the principle of the pressure pad Coating device 100 is based. That facing the roller 3 The pressure pad 40 places the squeegee 160 against the roller 3. In operation, when the roller 3 rotates in the direction of the arrow, there is a line force K perpendicular to the doctor blade 160 to the plane E, the doctor tube 113 parallel to the web strives to take along and it without special measures is able to bend.
- an additional Pressure pad 70 is provided, which is perpendicular to the plane E acts and stabilizes the doctor tube 113 against the force K. and holds straight.
- the doctor tube is also 113 relatively thick-walled. Its size is approximately up to Middle, axially parallel, flat cutouts 138 are attached, their middle to the milled 138 vertical boundary surfaces the actual ones Form doctor blades 160.
- the roller 3 and the doctor tube 13, 113 are in the Practice carried out so that the product of area moment of inertia and modulus of elasticity at every point of the roller 3 and of the doctor tube 13, 113 along its axes constant and at the roller 3 and the doctor tube 13, 113 is the same. Thereby can also in the case of changes to the doctor tube 13, 113 in Line gap acting line force while adjusting the pressure in the support device the gap height h on the doctor blade 160 be maintained evenly across the working width.
