Description

The invention relates to a device for the indirect or direct application of a liquid or pasty application medium to a movable material web, comprising a functional unit with an applicator and a device for metering application medium and a functional unit at least indirectly supporting carrying unit.

Devices for direct or indirect application of a liquid or pasty application medium are exemplary in the publications EP 0 846 804 B1 and EP 07 81 608 A2 described.

From the publication EP 0 846 804 B1 In this case, a device is known in which at least one elongated functional unit in direct contact with the application medium and an elongate support element carrying the at least one functional unit are provided. Since the application medium pumped by the device is usually heated as a result of the flow through various device components and by circulation devices or by the action of extra heating means, there are significant temperature differences between the application medium, heated by the application medium portions of the functional unit and the colder support element, which are reflected in changes in length, which are exposed depending on the connection between the support unit and functional unit very high voltages. The deformations also lead to an impairment of the order. To avoid the at least one functional unit is connected to the support member via a plurality of individual spaced-apart webs, a thermal shielding of the functional unit and the support member against each other and a Allow compensation of thermally induced relative changes in length between the functional unit and the support element. Due to the thermal decoupling of support unit and functional unit, the different length expansions of these and their consequences can be largely avoided, however, in devices for applying liquid or pasty application medium with an applicator and one of these functionally downstream equalization device, which is mounted on the applicator after as observed before severe deformation of individual components, in particular the equalization device, which can lead to a delay or to bending in relation to the surface to be coated, unless appropriate countermeasures are taken. The deformations can be considered in the longitudinal direction of the applicator lead to considerable inaccuracies in the order or make a constant readjustment or a complicated deflection compensation system required.

From the publication EP 0 781 608 A2 a device for applying application medium is previously known, in which means are also provided in the connection between the support unit and the functional unit, which allow a relative movement between them, in particular under the influence of thermal expansion. Again, by analogy with this, that the different thermal expansions in embodiments of the functional unit of a plurality of individual components are not excludable.

The invention is therefore based on the object, a device for direct or indirect application of application medium of the type mentioned in such a way that deflections within the functional unit as a result of different changes in length and changes over the longitudinal extension of the functional unit considered as simple as possible and avoided changing constraints on a job process are customizable to achieve high quality job results.

The solution according to the invention is characterized by the features of claim 1. Advantageous embodiments are described in the subclaims.

A device according to the invention for the indirect or direct application of application medium to a movable material web, comprising a functional unit with an application device and a device for metering application medium and a carrying unit which is at least indirectly the functional unit, is characterized in that means for thermal decoupling between the application device and the device for metering application medium are provided.

On the one hand, the solution according to the invention enables a desired thermal shielding between the application device, in particular the application media supply and the device for metering application medium, whereby the length changes caused by these can be compensated in a simple manner and, furthermore, optimum functioning of the entire functional unit can be guaranteed can.

In the context of the invention, a functional unit is understood to mean any application concept-specific device which comes into direct contact with the latter for the processing and manipulation or manipulation of the application medium and / or the order produced with the application medium. This comprises at least one application device and a device for metering the application medium, which can be designed as a separate structural unit or else can be part of the application device. For example, these may include pre-and end metering devices, such as a free-jet applicator, including paint distribution tube, supply channels, and applicator nozzle. Application work with a coating chamber, so-called "Short Dwell Time Applicators" (SDTA), "Long Dwell Time Applicators (LDTA)", leveling or Fertigdosiereinrichtungen with one or more Squeegee elements. The functional unit may further comprise various assemblies or individual parts to ensure, if necessary, replacement or maintenance of these components, in particular the parts exposed to high wear.

Application device is understood to mean a device which makes possible an application of media to the surface to be coated. This generally includes an application media supply and an applicator chamber or nozzle coupled thereto.

The inventors have recognized that a separation of the application medium contacting parts of the application medium supply and the device for metering application medium and the provision of the thermal shield between these components, which are connected via a rule formed by the rib-shaped elements Längenauspehnungskompensationseinrichtungen that in conventional devices occurring adverse deflection phenomena can be effectively minimized in a simple manner or even completely avoided.

The thermal decoupling thereby prevents heat transfer from the application device, in particular the application media supply to the device for metering application medium and thus a conditional by differently tempered areas deformation of these components themselves, while the designated means these preferably firmly connect with each other, but at the same time an unhindered linear expansion of these allows both relative to each other, so that a deformation caused due to the heated coating medium does not transfer to the means for metering. As a result, the device on the one hand can be made very dimensionally stable in terms of its operation and works very precisely even without further additional measures. The use of relatively complex and expensive deflection compensation systems is generally superfluous. these can be additionally used, but considerably reduced in size and simplified in terms of the required deflection compensation requirement.

Another advantage of the solution according to the invention is that different materials and materials can be selected between the individual elements of the functional unit. In this case, for example, special materials can be used for the parts contacting the application medium.

Furthermore, a separate production between the metering device and the application device is conceivable, wherein the individual components can now be provided in a standardized construction.

The thermal decoupling can be done directly between the applicator and the device for metering or indirectly. In the first case, the means for thermal decoupling between application device and means for metering are arranged. The connection of the functional unit can then be done by connecting the applicator or the device for metering application medium with the support unit. The first option offers the advantage of a more compact design. In the second case, the connection of the device for metering application medium and the Aufragseinrichtung takes place each directly to the support unit, free of a connection with each other and the thermal decoupling via the connection between the support unit and functional unit, in particular the applicator and the device for metering application medium. The means for thermal decoupling of application device and device for metering application medium are formed by the means for thermal decoupling of support unit and functional unit.

Furthermore, in both cases it is possible to use the means solely by the provided additional intermediate elements, preferably in the form of rib-shaped elements or webs and the enclosable between them Form air layer. In this case, the means are formed directly by the connecting elements, which are further designed and configured to compensate for a deformation, in particular length extension of the connecting elements. Furthermore, it is possible to integrate insulation material specifically in the connections between applicator device and device for metering. In particular, insulation layers on the individual components of the application device and / or the device for metering are conceivable.

The thermal insulation layer may be air, a coating applied to the respective elements that can be coupled to one another via the rib-shaped elements-application device and device for metering-or separate elements with insulating properties that are integrated into the connection. The design of the insulation layer is preferably adapted to the respective geometry of the mutually associated connection surfaces of the functional unit and of the support element, wherein the insulation layer can also assume sealing functions.

When using a gaseous medium, in particular air as a thermal insulation layer, it is advantageous if it is moved, for example by means of a blower, whereby the shielding effect is improved and also an additional cooling effect can be achieved.

The connection between the application device and the device for metering preferably takes place detachably, so that they can be easily separated from one another for maintenance purposes or for exchange with other elements, in particular during wear. Furthermore, this also makes it possible to couple different components and different designs of applicators and metering units with each other. The connections are non-positive or positive.

According to an advantageous embodiment, the individual components in the connection can also be designed and arranged to be movable relative to one another be, which allows for easier compensation of manufacturing tolerances and an adjustment in positioning their position to each other.

In a particularly advantageous embodiment, the inventive solution for a functional unit from an application device with a job media supply and at least one application nozzle and a leveling device, which is arranged separately from the actual application nozzle used. The leveling device is preferably a doctor element which extends in the width direction of the surface to be coated. The thermal decoupling is preferably carried out between the doctor blade associated Rakelhalterung and the order medium supply the applicator, wherein the applicator is used simultaneously with for clamping the doctor element.

In an advantageous further development, furthermore, a thermal decoupling between the functional unit, in particular the application device and the support unit, is provided. The same advantages apply.

To illustrate the individual directions coordinate systems are shown in the individual figures, the X direction corresponds to the longitudinal direction and in the installed position usually the machine direction. The Y-direction corresponds in installed position of the illustrated elements of the width direction and thus the direction transverse to the longitudinal direction, while the Z direction describes the height direction.

The FIG. 1 illustrates in a simplified schematic representation of the structure of an inventively designed device 1 for direct or indirect application of a liquid or pasty application medium 2 on a movable, in particular moving material M. The material web M is preferably in the form of a fibrous web, in particular as a paper or board web. The device 1 comprises a preferably multi-part functional unit 4 which is supported on a support unit 3, in particular in the form of an elongate support beam. This usually comprises at least one application device 5 with a coating medium supply 6 and a Depending on the design, the device 7 for metering application medium 2, which is also referred to as a metering device, either an integral part of the application device 5 or as a separate component within the functional unit 4 in the form of a gleichmäßigungs- or Equalizing present. The order of the coating medium 2 takes place either indirectly on a carrier surface 9 formed by a counter-roller 8, from which the order then takes place on the material web M, or directly on the supported by the counter-roller 8 web M. The direction of rotation of the counter-roller 8 is in the drawing illustrates by means of an arrow. According to the invention, means 10 for thermal decoupling of application device 5, in particular application media supply 6, and device 7 for metering application medium 2 are provided. These are arranged directly between the Aufragseinrichtung 5 and the device 7 for metering application medium 2. Furthermore, means 11 for thermal decoupling of the functional unit 4 and the carrying unit 3 are provided in the illustrated case. The applicator 5 is exemplified as a nozzle applicator comprising at least one over the width of the material to be coated web M or the support surface 9 extending applicator, here denoted by 12, which is coupled to the order media supply 6, which at least one, preferably over the entire Width of the material web to be coated M extending distribution channel 13 includes, which is coupled to the respective application nozzle 12. The exit from the application nozzle 12 takes place on the support surface 9 or supported by this material web M. The application device 5 downstream in the functional direction is the device 7 for metering the application medium 2, here in the form of a leveling device 14, extending over the entire width of the support surface 9 extends. The leveling device 14 comprises a doctor element 15, which is mounted in a doctor blade holder 16. The squeegee holder 16 comprises means 17 for fixing the squeegee element 15, in particular for clamping, and further means for positioning and for generating a corresponding pressing force against the mating surface in the form of a pressing device 19 for realizing a corresponding metering gap 18. Doctor blade element 15 and blade holder 16 thereby form a structural unit, which is designed in several parts. The pressing device 19 preferably comprises a pressing element 20 which extends across the width and generates a constant or variable pressing force acting on the doctor element 15 and positions it relative to the support surface 9 and holds it in this position. About the positioning of the doctor element 15 relative to the support surface 9 of the metering gap 18 is set in width and thus the corresponding layer thickness of the application medium 2. The individual elements of the equalizer 14, in particular the means for clamping 17 and the pressing device 19 are formed in several parts. In the case shown, the doctor element 15 is clamped by the means 17 for attachment between the application nozzle 12 and the doctor blade holder 16. This is realized by way of example by generating a corresponding clamping force. The pressing device 20 comprises in the simplest case, a pressing element, which is also mounted in the doctor blade holder 16. In the illustrated case, this example comprises a pressure bar 21, on which an elastic element 22 is mounted, which is effective with its directed to the doctor element 15 surface at this. The pressure bar 21 is mounted movably in the longitudinal direction relative to the doctor element 15 and thus enables the adjustment of the corresponding metering gap 18. The means 10 for thermal decoupling between the device 7 for metering application medium 2 and the application medium supply 6, in particular the application device 5, include illustrated case web or rib-shaped elements 23, in particular a plurality of in the longitudinal direction of the functional unit 4, which corresponds to installation position of the width direction of the device 1 and thus Y-direction, spaced from each other arranged rib-shaped elements 23, at both ends of each device 7 and the application medium supply 6, in particular the application device 5, are arranged. Furthermore, this can be used to attach the device 7 for metering application medium 2 to the actual application device 5. The rib-shaped elements 23 are formed in the illustrated case such that these with their vertical Direction top end portion 24 are connected to the doctor blade holder 16 of the device 7 for metering application medium 2 and further in a vertically lower end portion with the actual application device 5 and the Auftragmediumzufuhr 6, in particular the application nozzle 12. The rib-shaped elements 23 are formed such that these are suitable to be coupled to the application nozzle 12 at at least two locations or articulation areas, a first articulation area 25.1 and a second articulation area 25.2, wherein between the two articulation areas 25.1 and 25.2, which are preferably arranged offset from one another in the vertical direction, the central distribution channel 13 is arranged. In this case, the rib-shaped elements 23 enclose the element receiving the distributor channel 13 at least by a partial region of its outer circumference. Furthermore, means 11 for thermal decoupling between the support unit 3 and the functional unit 4 are provided. These are likewise a plurality of rib-shaped elements 26 which are arranged at a spacing from one another transversely to the longitudinal direction and which are connected in each case to the carrying unit 3 and the functional unit 4 in their end regions, in which case the connection with the application device 5 or the application medium feed 6 takes place. The rib-shaped elements 26, which can also be referred to as webs, take over the thermal decoupling of the functional unit 4 from the support unit 3 and also the rib-shaped elements 23 thermal decoupling of the device 7 for metering application medium from the application medium supply 6 and the actual application device 5 in Form of the application nozzle 12. These allow a thermal shielding of the individual functional units or elements against each other and a compensation of thermally induced relative changes in length. The thermal shield can be further improved by at least one thermal insulation layer, which is preferably formed from air, wherein the individual rib-shaped elements 23 and 26, so to speak, bridge the thermal insulation layer. The connections between the means 10 for thermal decoupling between the means 7 for metering of application medium 2 and the order media supply 6 and the Application device 5 is preferably detachable. This possibility offers the advantage of a corresponding adjustability of the position assignment to one another. However, it is also conceivable compounds in non-detachable form, for example cohesive compounds in the form of welded joints. The connection may also be made in releasable connection with mobility within the connection in at least one direction.

According to a particularly advantageous embodiment, the elements coupled to one another via the means 10, in particular the means 7 for metering application medium 2 and the application medium supply 6-containing elements, in particular the applicator 5, are made of materials which have the same or substantially the same coefficient of thermal expansion.

Recognizable in FIG. 1 is also a Auftragmediumauffangeinrichtung 31, which serves to collect and remove excess application medium 2.

The FIG. 2a illustrates a section of an embodiment according to FIG. 1 in which only the already known from the prior art thermal separation between the support unit 3 and the functional unit 4 is shown. Visible here is the support element, in particular the support beam of the support unit 3 and a part of the functional unit 4, in particular the application medium supply 6 and the application nozzle 12, which form the application device 5. The support beam of the support unit 3 is preferably formed as a hollow cylindrical element, on the outer circumference 27 over a portion of its extension in the circumferential direction, the means 11 for thermal decoupling between support unit 3 and functional unit 4 are hinged or connected to the support unit 3. In the case shown, the individual rib-shaped elements or webs 26 extend with their end portion facing the support unit 3 over a portion of the outer periphery 27 in the circumferential direction of the supporting beam of the support unit 3, wherein the articulation in a closed hinge region in the circumferential direction or as in the FIG. 2a shown at two circumferentially spaced hinge portions 29.1 and 29.2 takes place. By analogy with this, the end region facing the application device 5 is likewise articulated or connected to the application device 5 in two articulation regions 28.1 and 28.2. The individual articulation areas 29.1 and 29.2 and 28.1 and 28.2 are arranged spaced apart from each other in the vertical and / or horizontal direction. This results in a higher stability. The arrangement of the articulation areas 25.1 and 25.2 takes place in such a way that, based on this nozzle design and the application medium supply 6, it enables optimum optimal support of the application device 5.

In contrast, illustrates the FIG. 2b based on a section according to FIG. 2a an illustration of the means 10 for thermal decoupling between the applicator 5 of the functional unit 4 and the means 7 for metering application medium, in particular the actual doctor blade holder 16. Also here this preferably comprises rib-shaped elements 23 which are formed as webs or connecting webs, and the doctor blade holder 16 and thus connect the device 7 for metering application medium with the actual application device 5. The connection takes place here in the two articulation areas 25.1 and 25.2, which are arranged offset from one another in the vertical direction. The individual rib-shaped elements 23 are guided in the circumferential direction around the application medium supply 6, in particular the central distribution channel 13.

The rib-shaped elements 23 and 26 are arranged offset to one another over the longitudinal extension of the functional unit 4. The individual rib-shaped elements 26, 23 can be arranged in the width direction of the device 1 either parallel to one another or at an angle to one another. Preferably, parallel arrangements are chosen to achieve optimum strength evenly across the width of the device 1. The rib-shaped elements 23 and 26 can also be profiled to ensure the support function.

The in the FIGS. 1 and 2 illustrated embodiments in the device 1 for direct or indirect application of coating medium 2 on a movable material web M are characterized here by a functional separation of applicator 5 and means 7 for metering application medium by the means 7 for metering the applicator 5 is functionally downstream and is arranged separately from this, but elements of the actual applicator 5 can be used to attach the device 7 for metering application medium, in particular for example for mounting. By analogy, the said embodiment can also be used for functional units 4, in which the device 7 for metering application medium 7 with the applicator 5 forms a structural unit, in particular in the formation of applicators 5 in the form of so-called free-jet nozzles, in which the order directly on the support surface 9 or supported by this material web M occurs. Such an embodiment is exemplary in the FIG. 3 played. In this it can be seen that here only the metering device in the form of the device 7 is formed by an element 30 of the application nozzle 12, in particular an outlet gap forming area, the change in position relative to the other elements of the application nozzle 12 has an altered outlet cross-section of this and in connection therewith with other exit parameters for the application medium 2 allows a dosage. An additional leveling device 14 is not provided here.

In all embodiments, preferably the support unit 3 is formed of a carbon fiber reinforced plastic.

Not shown, but also possible, is the provision of special thermal insulation layers in the connections between application device 5 and device 7 for metering and functional unit 4 and support unit. 3

The FIG. 4 illustrates an alternative connection of the functional unit 4 to the support unit 3. Again, the application device 5 and the device 7 for metering application medium in the form of a homogenizing device 14, as in FIG. 1 described run and connected to each other via rib-shaped elements 23, which form the means 10 for thermal decoupling between application device 5 and means 7 for metering application medium. The connection between the functional unit 4 and the support unit 3 via other rib-shaped elements 26, which are also part of the means 11 for thermal decoupling between support unit 3 and functional unit 4. In this case, however, the connection of the application device 5 takes place via the coupling with the device 7, in particular the metering device on the support unit 3. A direct connection between the application device 5 and support unit 3 is not provided. The connection between the applicator 5 and the support unit 3 is thus indirectly via the connection of the device 7 for metering application medium with the support unit 3. The function of thermal decoupling can be taken directly from each of the individual rib-shaped elements 23 and 26. The connections between the individual rib-shaped elements 23, 26 and the connecting elements can be non-positive or positive or cohesive. Furthermore, this can be carried out detachably or permanently. Within the connections, an insulating layer may be provided or formed by the rib-shaped elements themselves.

The FIGS. 5a and 5b illustrate with reference to two views of a further embodiment in which the applicator 5 are connected by means of individual rib-shaped elements 23 and the device 7 via further rib-shaped elements 32 to the support unit 3, wherein there is no direct connection between applicator 5 and device 7. In the FIGS. 5a and 5b For this purpose, the individual connections are shown in different parallel sectional planes. In this case, preferably, the arrangement of the rib-shaped elements 26 and 32 in the longitudinal direction of the support unit 3, which the direction of extension of the longitudinal axis of the support unit and thus the Y-direction in Mounting position corresponds to alternate. In this case, a symmetrical arrangement is preferably selected with respect to the center of the longitudinal axis of the support unit 3. The distances between the individual rib-shaped elements 23 and 32 can vary or, preferably, be kept constant in order to realize equal force ratios over the longitudinal extent along the longitudinal axis of the carrying unit 3.

The individual rib-shaped elements 26 and 32 are part of the means 11 for thermal decoupling of support unit 3 and functional unit 4 and thus also the means 10 for thermal decoupling of application device 5 and device 7 for dosing.

The solution according to the invention is not limited to the exemplary embodiments illustrated in the figures. These are merely for the general explanation of the basic idea of the invention. Within the scope of protection, the device according to the invention may also assume other than the above-described embodiments. The device may have features that represent a combination of the respective individual features of the claims. Furthermore, deviating shapes for the individual functional elements can be selected with regard to the geometric configuration. Likewise, the thermal insulation layer may have another, preferably the respective geometry of the functional unit 4, the support unit 3 and the connecting device adapted design or it may also be a different type of thermal decoupling be selected, for example by specially used materials.
