Definitions
- the invention relates to a device for curtain coating a moving substrate, preferably a flexible endlessly conveyed web.
- curtain coating is one of many methods of coating flexible, endless webs with a thin liquid film.
- the method is suitable for applying a layer of a single liquid or simultaneously several layers of different liquids.
- the curtain coating process has been known and researched for many years. For example, a detailed description will be provided Miyamoto and Katagiri, Curtain Coating, in Liquid Film Coating, Chapter 11c, Chapman & Hall, New York 1997 ,
- the curtain is either wider or narrower than the web to be coated. If a liquid curtain is not guided laterally along its fall line, it contracts as a result of surface tension forces. As a result, the control over the width of the curtain and therefore also over the casting width at the point of impact of the curtain on the web to be coated is lost.
- a non-guided curtain in industrial applications is at most interesting if the curtain is much wider than the web to be coated and consists of a single liquid. In this case, the excess liquid can be collected and reused. In all other applications, especially when the curtain is made up of several layers of liquid, it makes sense to vertically guide the curtain on both sides to keep the curtain width constant and liquid losses small. For guided liquid curtains, a boundary system is advantageous.
- a prerequisite for the successful application of the curtain coating process is a stable liquid curtain.
- a sturdy curtain is characterized by robustness against internal and external disturbances, ie it can not be permanently destroyed by the disturbances.
- Theoretical and experimental investigations of the stability of liquid curtains can be found in, for example, Brown, DR, 1961, A study of the behavior of a thin sheet of moving liquid, J. Fluid Mechanics 10, pages 297-305 and Taylor, GI 1959, The dynamics of thin sheets of fluid, Part III: Disintegration of fluid sheets, Proc. Roy. Soc. London A, pages 253-313 ,
- Brown has defined the following stability criterion for liquid curtains: The curtain is stable when the fall velocity is greater than the propagation velocity of curtain disturbances. Under this condition, disturbances can not propagate against the downward falling motion, but are swept down and therefore can tear the curtain at most locally and temporarily, but not catastrophically.
- a slot nozzle or a cascade nozzle, as described by way of example by Miyamoto and Katagiri.
- the curtain forms directly at the outlet of the nozzle slot.
- the liquid flows after exiting the nozzle slot first in the form of a single or multi-layered liquid film on the nozzle surface to the nozzle lip. Only at the nozzle lip, the film flow turns into a curtain flow. So that the film flow on the nozzle surface remains well-defined in its width, it should be guided laterally by means of a nozzle side boundary.
- the wetting line When a free surface liquid is confined laterally by a wall, the wetting line will be either above or below the liquid surface, depending on the wetting properties between liquid and wall material due to capillary forces, with good wetting, such as for example Weinstein, SJ and Palmer, AJ, Capillary hydrodynamics and interfacial phenomena, Chapter 2, in Liquid Film Coating, Chapman & Hall, New York 1997 , describe.
- the shape of the liquid surface therefore changes along the boundary. The changes can be particularly strong as the liquid flows along the side boundary. This is for example from Schweizer, PM, 1988, Visualization of coating flows, J. Fluid Mechanics 193, pp. 285-302 , shown.
- curtain coater and in particular their nozzle side boundaries are, for example, in the DE 30 37 612 C2 and the WO 94/08272 described.
- the falling curve of the curtain is heavily dependent on the type of nozzle used to create the curtain. If a slot die is used, the curtain will fall substantially vertically in the extension of the die slot, especially if the curtain is a single liquid. If, on the other hand, a cascade nozzle is used to generate the curtain, an asymmetrical flow field results in the vicinity of the nozzle lip, which leads to a deflection of the curtain fall curve from the vertical. In particular, the curtain curves below the nozzle lip to the rear, which is called "tea-pot effect" ( Kistler, SF and Scriven, LE, 1994, The tea-pot effect: sheet-forming flows with deflection, wetting and hysteresis, J. Fluid Mechanics 263, pages 19-62 ). When designing the curtain side boundary, this effect should be taken into account.
- the DE 10 2004 016 923 A1 discloses a curtain coater according to the preamble of claim 1.
- the present invention thus avoids problems that arise with only separately adjustable folding devices, since in such a single operation of soabkantungsvoriquesen flow situations can again arise which jeopardize or limit the stability of the coating curtain section.
- the present invention is also envisioned as a method that progressively translates the physical characteristics of the curtain coater described herein to provide optimum coating.
- the soabkantungsvoriques is arranged in the flow of the coating liquid after the nozzle device and in front of the curtain guide structure, and so follows the curtain guide structure functionally the bending device, so that always ensures a sufficient guidance of the curtain and thus the stability is given.
- the The isabkantungsvorraum can be adjustable by means of a rail device, and this rail device can be arranged in particular on the nozzle device. It is possible to connect the Soabkantungsvorides and / or the shape guide structure via a rail attack slidably and lockable with the rail device.
- the adjustability can be ensured in different ways.
- a manual adjustability or displaceability is readily conceivable for such cases, where over a long time a certain width setting for the curtain should be set permanently.
- motor adjustability is suitable for systems which often require different coating widths.
- the soabkantungsvorraum be mechanically or mechanically detectable, depending on the requirements and the frequency of Verstellvortician.
- the side bender may be one having a separating edge and a receiving and discharging device for the folded coating liquid on the outside.
- the nozzle device of the curtain coater may comprise the following components: a nozzle surface inclined to the horizontal; an outlet opening, through which the coating liquid of the nozzle surface is fed so that the Coating liquid forms a downflowing film on the nozzle surface; a nozzle lip forming a downstream end of the nozzle surface; and a nozzle boundary for laterally limiting the film flow.
- a nozzle side boundary adjustable in the width direction, and this adjustability can functionally interact with the adjustability of the side bender / curtain guide structure to optimally shape the mold properties and thus the coating.
- FIG. 1 shows a curtain coater with a nozzle device 4, which is arranged vertically above a roller 3 at a clear distance.
- the roller 3 serves as a deflection device, or more generally as a support device, for a substrate 1 to be coated, which is conveyed in a loop over the roller 3.
- the substrate 1 is an endlessly conveyed, flexible web.
- the nozzle device 4 is a slot nozzle in which separate feeds for several, in the embodiment, two different coating liquids are formed. The feeds converge on a substrate 1 facing the lower end of the nozzle device 4 in a nozzle outlet opening.
- the outlet opening extends slot-shaped transversely to the conveying direction of the substrate 1 over a width which is larger as the coating width to be achieved of the product formed from the substrate 1 and the coating 2. In principle, however, the width of such an outlet opening can also be smaller than the coating width to be achieved.
- the two coating liquids leave the outlet opening of the nozzle device 4 freely falling as a two-layer liquid curtain V.
- the nozzle device 4 is arranged relative to the roller 3 so that the curtain V with a rotation axis of the roller 3 spans a vertical plane when the curtain V is not disturbed ,
- FIG. 2 shows a curtain coater with a nozzle device 4, which is formed as a cascade nozzle. It has a nozzle surface 5 which is inclined to the horizontal, so that a coating liquid supplied to the nozzle surface 5 flows downward on the nozzle surface 5 to a nozzle lip 6 forming the downstream end of the nozzle surface 5 and flowing freely beyond the nozzle lip 6 Curtain V passes.
- the nozzle surface 5 are supplied via outlet openings 7 of the number of outlet openings 7 corresponding to a plurality of different coating liquids which form on the nozzle surface 5 in a known manner a multilayer film flow F, which flows through the nozzle lip 6 in the curtain V.
- the outlet openings 7 are slit-shaped and extend transversely across the width of the nozzle surface 5.
- the nozzle surface 5 is in its, over the outlet openings 7 extending upstream portion plan, d. H. it forms an inclined plane there. In a subsequent downstream portion, the nozzle surface 5 is curved with its inclination gradually increasing to provide a continuous transition to the downstream end of the nozzle lip 6.
- FIG. 3 An overview of a curtain coater according to the invention is the figure 3 as a perspective view.
- the nozzle device 4 is shown as a cascade nozzle, the curtain not being shown here for the sake of clarity.
- the side bending device 11 engages from the left side. It comprises a separating edge 12 which divides the curtain falling from the die lip 6 into two parts, namely a coating curtain part falling right in the drawing to the center of the nozzle surface and a separated curtain part which is located to the left of the edge 12 in the collecting and Drain trough 13 enters and is discharged through the conduit 14.
- FIG. 4 shows the guide 15 of the curtain guide structure 16 more clearly, wherein the guide 15 is designed as a convex guide surface in order to be able to precisely determine the falling line of the curtain, to minimize tension forces in the curtain and to reduce boundary layer effects.
- the side bender 11 and the curtain guide structure 16 are unitarily adjustable in the widthwise direction, and this width adjustability is ensured by a rail 21 attached to the lower inclined surface 8 of the nozzle and in FIGS. 3, 4 and 5 can be seen.
- the soabkantungsvoriques 11 can be adjusted together with the curtain guide structure, whereby the width of the curtain can be adjusted and it is always ensured that the folded curtain residue drained well and the coating curtain are well down to the substrate.
- the rail 21 on the lower nozzle surface 8 carries a guide element 22, which is shown in Figures 3, 4 and 5 as a transparent component.
- the guide element 22 forms, so to speak, the "transition" between the rail 21 and a bracket 25, which is already regarded as a support member on the side of the curtain guide structure 16.
- the guide member 22 is fixed to the rail 21 with individual and spaced-apart countersunk screws 23 (with hexagon head).
- the other components described are best seen in Figure 5.
- the clamp 25 and the handwheel screw 26 engage from above or from below on the guide element 22 and thus provide a firm connection of the support structure 24 with the guide element 22.
- the carrier structure 24 is in turn secured to the curtain guide structure 16 by knurled screws, which can be seen from the outside in FIGS.
- curtain guide structure 16 and, of course, the adjoining side bending device 11 takes place in the following sequence: curtain guiding structure 16 , Carrier structure 24, hand screw 26 and counter clamp 25, guide element 22, fastening screws 23, rail 21 and surface 8 on the nozzle 4.
- the illustrated manner of attachment has the advantage of great flexibility.
- the fastening on the guide element 22 can be easily loosened and tightened again with the hand screw 26 so that an adjustment of the curtain width can be effected in a simple manner.
- the thumbscrews that attach the curtain guide structure 16 to the support structure 24 are also easily releasable, and thus, a simple replacement or removal of the curtain guide structure 16 for cleaning or maintenance purposes.
- FIGS. 3 to 5 makes it possible to carry out the width adjustment of the curtain in a simple and reliable manner, although of course other fastening, connecting and adjusting devices are conceivable in the context of the present invention, for example motor detection and displacement or stepwise Adjustability or provision of stops for special curtain widths to be preset.
