Definitions
- the present invention relates to an apparatus and a method for curtain coating (English Curtain Coating) for applying thin films on moving substrates.
- the invention relates to a device for guiding the side of coating curtains and a method for using this device.
- Such devices are used for example in the coating of paper, adhesive tapes or even in the coating of photographic films.
- a corresponding coating liquid for example a solvent or else a dispersion or solution
- a corresponding coating head By means of a correspondingly shaped casting gap or a corresponding pouring lip, the coating liquid is formed into a free-falling curtain, which impinges on a substrate moving transversely to the direction of fall of the curtain.
- Typical speeds for the movement of the substrate are for example in the paper coating in the range of a few 100 m / min.
- a curtain holder is known in which the edges of the curtain are stabilized by means of threads or wires. Through a construction of different pulleys moves at each edge of the curtain, a corresponding thread or wire in the direction of the curtain to which the curtain adheres.
- the device described in GB 2 021 001 A is technically very complicated.
- the stability of the described curtain holder suffers from the fact that the speed of the thread or wire is not optimally adapted to the falling speed of the curtain at every point, as a result of which instabilities can occur.
- Another way of stabilizing the edges of the curtains is to provide rigid curtain holders which are wetted with an auxiliary liquid.
- the auxiliary liquid can partially move with the freely falling curtain and thus compensates for the difference in speed between the rigid curtain holder and the free-falling curtain.
- Such systems are described for example in EP 0 737 521 A2.
- the supply of an auxiliary liquid to the surface of a curtain holder is effected by a porous plate whose thickness may have a gradient, so that the auxiliary liquid moves in the optimum case at the same speed in the direction of fall as the edges of the curtain.
- a disadvantage of the devices and methods described, however, is that, especially when using solutions and dispersions, the guide surfaces of the curtain hangers are easily contaminated or the porous materials are easily clogged by the coating liquids used. This requires complex cleaning steps and requires high maintenance times of the system. The operating time between required maintenance and cleaning operations decreases with the age of the curtain holder, since the porous materials can never be completely cleaned. Furthermore, as a result of local blockage of the porous surface, local overdosing of auxiliary liquid occurs. In addition, the porous materials used typically have a high surface area. surface roughness and thus a high flow resistance. Furthermore, the mitge ⁇ introduced auxiliary liquid films are often comparatively wide with several 10 mm compared to the typical thicknesses of 0.3 mm of the coating curtains.
- auxiliary liquid at the lower end of the curtain holder is often not completely sucked off, which can lead to inhomogeneities in the film thickness (bead formation) of the coated substrates in the edge region.
- EP 0 740 197 A1 describes a device in which a film of an auxiliary liquid is applied to the surface of a side guide by means of a horizontal dosing slot perpendicular to the curtain, which is aligned with the edge of the side guide
- the liquid film may be limited in its width.
- the device described in EP 0 740 197 A 1 has the disadvantage that, in particular shortly below the pouring lip for supplying the auxiliary liquid to the side guide device, turbulences occur in the auxiliary liquid film, which are caused in particular by the auxiliary liquid being perpendicular to the
- Drop direction of the curtain is fed to the surface of the side guides to be finally deflected there by 90 °.
- the curtain producer can be, for example, a commercially available nozzle of a commercial curtain coater, for example a simple nozzle or even a cascade nozzle for producing a liquid curtain consisting of several individual layers.
- curtain producers with simple casting devices with one or more pouring lips are also conceivable. In this case, it is assumed that the fluid curtain produced falls essentially vertically in the vertical direction.
- the side guide device has a side guide body with a guide surface.
- This side guide body can in particular directly or indirectly via an intermediate piece (for example, a separating plate) connected to the curtain generator, spielmik be screwed.
- the separating plate or intermediate piece forms part of the entire lateral guiding device.
- the side guide body and the separating plate may for example be wholly or partly made of aluminum, stainless steel, treated steel (eg chromium-plated or nickel-plated steel, etc.) or plastic or consist of different materials.
- a side guide groove is embedded in the guide surface of the side guide body. This side guide groove extends substantially vertically when the side guide device is used for stabilizing a freely falling coating curtain.
- the lateral guide groove has at least two partial regions, a calming bridge and a guide route arranged below the calming section.
- an auxiliary liquid inlet for introducing an auxiliary liquid is introduced into the side guide groove in the side guide body, wherein the auxiliary liquid inlet o is disposed above the calming section.
- a liquid drain is furthermore provided in the side guide body. The stabilization of the coating curtain takes place in that auxiliary liquid flows in a vertical direction through the side guide groove, the auxiliary liquid being in contact with the liquid, freely falling coating curtain.
- An essential feature of the present invention is that the auxiliary liquid in the flow region of the side guide groove no longer has any or only slight horizontal components.
- the movement of the auxiliary liquid thus takes place virtually completely parallel to the movement of the coating curtain, which additionally reduces the likelihood of the coating curtain tearing off from the auxiliary liquid.
- An essential component of the invention is therefore the aforementioned calming section, which serves to transfer the flow of the auxiliary liquid after it has been introduced into the flow region via the auxiliary liquid inlet from a turbulent flow into a laminar flow in the vertical direction.
- the coating curtain is out of contact with the auxiliary liquid to prevent transfer of transverse components of the auxiliary liquid velocity which may still be within the settling section to the coating curtain, thus further increasing the likelihood of the coating curtain tearing off to verrin ⁇ like.
- the auxiliary liquid inlet may have a bore running essentially perpendicular to the guide surface, via which auxiliary liquid is introduced into the lateral guide groove in the horizontal direction, in order then to be deflected there by 90 °.
- all the velocity components or pulse components of the auxiliary liquid are then gradually degraded perpendicular to the guide surface, and the movement of the auxiliary liquid is converted into a laminar flow in the vertical direction.
- the side guide device additionally has a separating device which completely or partially separates the auxiliary liquid in the settling section from the coating curtain or the coating liquid.
- This separating device may for example be a separating plate, which covers the cornering groove in the area of the calming section and the side guide device of the Curtain generator separates.
- the calming section should have a length of more than 3 mm, preferably a length of 5 to 7 mm.
- a compulsory mixing section can additionally be provided in the lateral guide groove, in particular between the calming section and the guide track.
- the forced mixing section should be arranged between the calming section and the guide track.
- the auxiliary liquid is in contact with the coating liquid when passing through the forced-circulation section before the coating liquid has left the curtain generator.
- the side guide device has a device for fastening the side guide device to the curtain generator, for example a simple device for screwing, in particular corresponding bores or threaded bores. It is then possible to use a commercially available curtain generator with a nozzle, wherein the side guide device is attached to the curtain applicator such that the auxiliary liquid is already in contact with the coating liquid before it has reached the nozzle tip of the curtain generator.
- the side guide device can form a wall of the curtain generator.
- the forced mixing between auxiliary liquid and coating liquid takes place over a length of 0.5 to 3 mm.
- the compulsory mixing can be carried out in such a way that the side guide device is fastened to a wall of the curtain generator via a separating device, in particular a separating plate.
- the separating plate separates the auxiliary liquid in the settling section from the coating liquid in the area of the settling section.
- the separating plate can then have a mixing slot in the region of the forced mixing section, within which a forced mixing between the auxiliary liquid in the forced mixing section and the coating liquid in the curtain generator can take place.
- the side guide device can be designed such that the at least one liquid drain has a suction gap, which opens onto the guide surface. In particular, this suction gap can be connected to a vacuum device for suction of the auxiliary liquid.
- This suction gap optimally opens at an angle other than 90 ° to the guide surface.
- angles in the range of 30 to 88 ° of the suction gap to the guide surface preferably even in a range of 40 to 75 ° and very particularly preferably in a range of 50 ° to 70 °, have proved to be particularly advantageous.
- the suction gap optimally has a width between 0.5 and 3 mm, preferably in the range between 1 and 2 mm and very particularly preferably a width of 1.3 to 1.6 mm, in particular of 1.5 mm.
- the lateral guide groove can in principle have any desired cross-section, that is to say in particular a rectangular, oval, round or V-shaped cross section.
- the side guide groove should in particular have a width of 0.5 to 1.5 mm, preferably in the range of 1 mm. This ensures that the consumption of auxiliary liquid, which in particular can be water, is minimized.
- the width of the side guide groove is just large enough to detect the thickness of the coating curtain, as well as minor variations (such as air movement) of the coating curtain.
- the auxiliary liquid is usually contaminated with coating liquid after passing through the guide section, the auxiliary liquid frequently has to be introduced into a wastewater system or a simple waste system from the environment protection is not possible.
- the proposed arrangement has the advantage over the arrangements described in the prior art that the need for auxiliary fluid is minimized.
- the lateral guide groove should have at least one point a depth of 0.5 to 1.5 mm, preferably in the range of 1 mm. In the case of many auxiliary liquids, for example in the case of water, this depth ensures that an adaptation of the vertical speed of the auxiliary liquid in the side guide groove from 0 (directly on the wall of the groove) up to the free fall speed, which also corresponds to the speed of the Coating curtain largely corresponds, can take place.
- the depth of the lateral guide groove can vary over the entire course of the lateral guide groove. Thus, it has proved to be advantageous if the depth of the side guide groove in the vertical flow region has a gradient region in which the depth of the side guide groove increases continuously downwards.
- the surface of the side guide device is at least partially reduced, in particular in the flow region, by suitable mechanical measures to a roughness of not more than 100 ⁇ m, preferably even between 25 and 75 ⁇ m.
- suitable measures include, for example, polishing processes or corresponding production processes which produce a low surface roughness, such as, for example, eroding. This ensures that the turbulence caused in the surface vortex and thus velocity components perpendicular to the direction of flow (ie in the horizontal direction) are minimized.
- the coating curtain is advantageous to introduce the coating curtain as far as possible to the substrate to be coated.
- continuous substrates for example paper webs or plastic webs. These are typically fed to the coating curtain via roller or shaft systems.
- the surface to be coated below the curtain generator is curved.
- the side guide device has a lower edge or surface, which extends completely or partially angled relative to the horizontal and / or at least partially has a concave course.
- a concave course is to be understood, for example, as a round milled-in area, the radius of this milled-in area ideally being adapted to the radius of curvature of the substrate to be coated at the point of impact of the coating projection.
- a curtain coater is proposed, in which a 10% substitutionsvor ⁇ direction is integrated according to one of the embodiments described above. Furthermore, a method for coating substrates by means of a curtain coating process is proposed in which at least one coating curtain is stabilized by at least one lateral guiding device according to the invention.

- the So ⁇ guide body 110 has a substantially rectangular mounting portion 112, by means of which the side guide body 110 can be attached to the coating head (see below, Figure 6).
- bores 114 through which the side guide body 110 can be fastened to the coating head by means of screws, are embedded in the fastening region 112 (see below, FIG. 6).
- the screw heads are sunk in the mounting portion 112.
- the attachment region 112 has a ventilation bore 116, which, with the side guide device fastened to the coating head, corresponds to a ventilation region of the coating head and allows pressure equalization to take place in the coating head.
- a substantially trapezoidal transition region 118 follows the attachment region 112 downwards, ie in the direction of the coating curtain, followed by an elongated guide element 120 brought in.
- a sawing or eroding method is particularly suitable.
- the lateral guide groove 122 has a rectangular cross section with a depth d (see FIG. 2 and FIG. 4) of 1 mm and a width b (see FIG. 1 and FIG. 3) of likewise 1 mm.
- the depth d is constant over the entire region of the lateral guide groove 122.
- the depth d can also increase downwards, ie in the direction of fall of the coating curtain.
- FIG. 2B An example of such an embodiment is shown in FIG. 2B.
- the depth d of the lateral guide groove 122 increases linearly towards the bottom.
- the lateral guide groove 122 has a depth di of 1 mm, immediately above the liquid flow outlet 142 a depth d 2 of 2 mm. In this way, a greater penetration of the coating curtain into the side guide groove 122 is ensured in the direction of fall (ie downward in FIG. 2B), which results in a more intensive and reliable downward stabilization.
- Various manufacturing processes for the production of the lateral guide groove 122 are conceivable. Depending on the chosen manufacturing process, there is additionally an additional post-treatment step by means of which the roughness of the side walls of the side guide groove 122 is reduced (see above).

- the supply bore 124 has a connection region 127 with a thread, via which, for example, a supply hose (not shown) can be connected to the supply bore 124.
- the feed bore 124 has a flow region 128 which ends immediately above the SoWestangsnut 122 in the guide surface 126.
- Auxiliary liquid, for example water, is deflected by 90 ° at the end of the flow region 128, in order then to move in a vertical direction through the lateral guide groove 122.
- the dashed contour 132 designates the boundary line above which in the assembled state (see, for example, FIG. 6 below) the attachment region 112 and (partially) the transition region 118 are covered by a separating plate (510).
- the boundary line 132 of the separating plate (510) has a mixing slot 134 in the form of a downwardly open U. Accordingly, the S.angs 122 is divided into three areas (see Figure 1):
- first region 136 immediately adjacent to the feed bore 124, which extends from the lower edge of the feed bore 124 to the upper edge of the mixing slot 134 and has a length of approximately 5 mm,
- a second region 138 (forced mixing section) which extends within the mixing slot 134 and has a length of about 2 mm
- a third region 140 (guide path) which comprises the remaining region of the lateral guide groove 122 and extends below the forced mixing section 138 as far as a liquid outlet 142.
- the auxiliary liquid As described above, the division of the side guide groove 122 into the three areas of stabilization of the curtain.
- the auxiliary liquid after being introduced through the feed bore 124 and corresponding deflection by 90 °, is first calmed in its flow. In this case, all speed components of the auxiliary liquid perpendicular to the guide surface 126 are eliminated and the flow is converted into a laminar flow in the vertical direction by the side guide groove 122.
- the auxiliary liquid Within the forced mixing section 138, the auxiliary liquid first comes in contact with the coating liquid and mixes with it. However, this takes place in an area within which the coating liquid has not yet left the coating head. Within the forced mixing section 138, possible turbulences resulting from the mixing of the two liquids are also compensated.
- the lower end of the guide element 120 is shown as cutout A or B in FIGS. 3 (A) and 4 (B), FIG. 4 not showing the variant embodiment of the side guide body 110 with a constant depth d of the side guide groove 122 according to FIG the alternative embodiment according to FIG. 2b represents.
- the lower surface 144 of the side guide device 110 does not run parallel to the horizontal but has both in the drawing plane according to FIG. 1 (front view, inclination angle ⁇ ) and in the plane of the drawing of FIG. 2 (side view, inclination angle ⁇ ). each at an angle different from 90 ° to the vertical. These angles serve a different purpose.
- the inclination angle ⁇ has an amount of 85 °, so that the surface 144 is tilted in the drawing plane according to Figure 1 by 5 ° to the horizontal.
- a round milling of the surface 144 may also take place, for example to bring the surface 144 as close as possible to a curved substrate surface (for example a substrate on a roll).
- the different inclination ⁇ in the plane of the drawing according to FIG. 2 serves the purpose of preventing capillary action when the lower surface 144 of the side-guiding body 110 is brought close to a substrate surface. If the surface 144 formed just to the substrate, as approaching a substrate surface could form a narrow cavity with parallel side walls, which attracts coating liquid of the curtain by the capillary action, whereby the coating would be smeared at the edges. In this embodiment, an angle ⁇ of 80 ° is used, so that the surface 144 is thus inclined in the drawing plane according to Figure 2 by 10 ° to the horizontal.
- the liquid outlet 142 has a gap 146 (see FIGS. 3 and 4) which opens onto the guide surface 126 at an angle ⁇ different from 90 ° (see FIG. 4).

- the side guide device 608 ie the side guide element 110 and the separating plate 510, is fastened to the coating head 610 as a side wall, so that the side guide device 608 functions as a wall element of the coating head 610 and closes off the gap 612.
- the coating head 610 produces a curtain 618 of coating liquid which falls vertically downward from the nozzle tip 614.
