Description

Die Erfindung betrifft ein\ Verfahren zum dosierten Aufbringen von Flüssigkeiten auf Materialbahnen gemäß dem Oberbegriff des Anspruchs 1 und eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a \ method for metered Applying liquids to material webs according to the preamble of claim 1 and a device to carry out the procedure.

Bekannte Verfahren in der Druckindustrie verwenden, insbesondere beim Offset- oder beim Tiefdruck, zum Aufbringen der Druckflüssigkeit Walzenwerke. Nachteilig ist dabei, daß teuere Ausrüstungen benötigt werden und ein hoher Reinigungsaufwand des Druckwerkes notwendig ist, wenn zum Beispiel ein Farbenwechsel erfolgen soll. Es treten hohe Materialverluste in den Walzenwerken und in den Wannen und ein großer Verschleiß der Walzenwerke auf.Use known processes in the printing industry especially in offset or gravure printing Application of the hydraulic fluid roller mills. adversely is that expensive equipment is needed and a high cleaning effort of the printing unit is necessary is, for example, if you want to change colors. There are high material losses in the roller mills and in the tubs and great wear on the roller mills on.

Zum Beschichten von ebenen Trägerschichten sind des weiteren allgemeine Sprühverfahren bekannt. Sprühverfahren weisen insbesondere den Nachteil einer hohen Umweltbelastung durch das offene System auf.For coating flat carrier layers are the known other general spraying methods. Spray processes have the disadvantage of one in particular high environmental impact due to the open system.

In der US 53 36 534 wird ein Verfahren zum Beschichten von Materialbahnen beschrieben, gemäß dem die Beschichtungsgeschwindigkeit durch Einwirkung von Ultraschall erhöht werden kann. Die Beschallung erfolgt auf die freie Oberfläche der Materialbahn von einem beabstandeten Horn aus. Dieses Verfahren ist uneffektiv, da die Einwirkung der Schallwellen über die Luft nicht zu der erwünschten Wirkung eines dosierten Auftrags von Flüssigkeiten führen kann.In US 53 36 534 a method for coating described by material webs according to which the Coating speed by exposure to Ultrasound can be increased. The sonication takes place on the free surface of the material web from one spaced horn. This procedure is ineffective since the effect of the sound waves over the Air does not deliver the desired effect of a metered dose Application of liquids can result.

In der WO-A-93/07969 wird ein Verfahren zum dosierten Aufbringen von Flüssigkeiten auf Materialbahnen beschrieben, um die Eigenschaften der aufgebrachten Beschichtung zu verbessern.WO-A-93/07969 describes a method for metering Applying liquids to material webs described the properties of the applied To improve coating.

Aufgabe der Erfindung ist es, die Nachteile des Standes der Technik zu beseitigen und ein Verfahren und eine Vorrichtung zum dosierten Aufbringen von Flüssigkeiten auf Materialbahnen zu entwickeln, mit denen eine homogene Beschichtung und eine minimale Umweltbelastung gewährleistet sind.The object of the invention is to overcome the disadvantages of the prior art to eliminate technology and a process and a Device for the dosed application of liquids to develop on material webs with which one homogeneous coating and minimal environmental impact are guaranteed.

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1 und des Anspruches 7. Die zu beschichtende Materialbahn wird mittels Druckluft oder mittels einer elastisch mitlaufenden Walze auf die Oberfläche eines Ultraschall-Schwingungssystems gedrückt und über die Oberfläche derart geführt, daß im Takt der angelegten Arbeitsfrequenz ein sich periodisch öffnender Spalt zwischen der Materialbahn und der Oberfläche des Schwingungssystems erzeugt wird, über den die Flüssigkeit auf die Materialbahn aufgebracht wird.The solution to this problem results from the features of claim 1 and claim 7. Die zu coating material web is by means of compressed air or by means of an elastically rotating roller on the Surface of an ultrasonic vibration system pressed and guided over the surface such that in Clock of the applied working frequency periodically opening gap between the material web and the Surface of the vibration system is generated over which the liquid applied to the material web becomes.

Durch die Anwendung von Ultraschall werden ein Verfahren und eine Vorrichtung aufgezeigt, mit denen eine gleichmäßige Dosierung und eine homogene Beschichtung gewährleistet werden und mit denen, infolge des geschlossenen Systems und der damit verbundenen geringen Materialverluste, keine oder eine geringfügige Umweltbelastung besteht.Through the application of ultrasound Method and an apparatus are shown with which an even dosage and a homogeneous Coating are guaranteed and with those as a result of the closed system and thus associated low material losses, none or one there is a slight environmental impact.

Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Advantageous embodiments of the invention are in the Subclaims specified.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles einer Vorrichtung zur Durchführung des Verfahrens näher erläutert. Es zeigen:

Fig. 1 :
eine Prinzipdarstellung der Vorrichtung zur Durchführung des Verfahrens nach der Erfindung in Schnittdarstellung und
Fig. 2 :

The invention is explained in more detail below with reference to an embodiment of an apparatus for carrying out the method shown in the drawing. Show it:
Fig. 1:
a schematic representation of the device for performing the method according to the invention in a sectional view and
Fig. 2:
the schematic side view in partial sectional view of the device of FIG. 1 (partially).

Die Vorrichtung nach den Fig. 1 und 2 wird aus einem Ultraschall-Schwingungssystem (Sonotrode) 1 gebildet, in welches eine Zuführung 2 für eine Flüssigkeit, hier zum Beispiel für einen Lack, vorgesehen ist. Oberhalb der Sonotrode 1 ist ein Luftkanal 3 zur Einleitung von Druckluft angeordnet.1 and 2 is made from a Ultrasonic vibration system (sonotrode) 1 formed, in which a feed 2 for a liquid, here for example for a lacquer. Above the sonotrode 1 is an air duct 3 for the introduction of Compressed air arranged.

Die zu beschichtende Materialbahn, hier zum Beispiel eine Folienbahn 4, wird über die Oberfläche der Sonotrode 1 geführt (Fig. 1).The material web to be coated, for example here a film web 4, is on the surface of the Sonotrode 1 performed (Fig. 1).

Die Sonotrode 1 besteht aus einer Ultraschall-Leiste, die beispielsweise aus einer Vielzahl parallel arbeitender Schallwandler aufgebaut ist, welche gemeinsam den Schwingungsbalken phasengleich anregen, aber voneinander gegen Querschwingen entkoppelt sind.The sonotrode 1 consists of an ultrasound bar, which for example consist of a large number in parallel working transducer is built, which together excite the vibration beam in phase, but are decoupled from each other against transverse swinging.

In einer anderen Ausführungsform könnte die Sonotrode auch aus einem Querschwinger gebildet sein.In another embodiment, the sonotrode could also be formed from a transverse oscillator.

Die Sonotrode 1 schwingt über die gesamte Arbeitsbreite mit exakt gleicher Amplitude A, Frequenz und Phasenlage.The sonotrode 1 swings over the entire working width with exactly the same amplitude A, frequency and Phasing.

Die zu beschichtende Folienbahn 4 wird mittels des mit Überdruck beauflagten Luftschachtes 3 auf die Oberfläche der Sonotrode 1 angedrückt. Anstelle von Druckluft kann auch eine elastisch mitlaufende Walze oder ein ähnliches Mittel verwendet werden, um die Folie 4 mit einer definierten Andruckkraft über die Sonotrode 1 zu führen. Es kann auch alleine durch die Wahl der Folienbahnspannung die notwendige Andruckkraft erreicht werden.The film web 4 to be coated is by means of Overpressure of the duct 3 applied to the surface the sonotrode 1 is pressed. Instead of Compressed air can also be an elastically rotating roller or a similar agent can be used to control the Slide 4 with a defined pressure force over the Lead sonotrode 1. It can also be done by the Choice of film tension the necessary pressure can be achieved.

Da die Folienbahn 1 infolge der Trägheit der durch die angelegte Schwingungsfrequenz erzeugten Beschleunigung der Sonotrode 1 nicht folgen kann, entsteht über der gesamten Breite der Folienbahn 4 ein Spalt 5, der sich mit der eingestellten Arbeitsfrequenz der Sonotrode 1 periodisch öffnet. Die Spaltgröße entspricht annähernd der Größe der eingestellten Amplitude A. Über den Spalt 5 wird der Lack gleichmäßig auf die Folienbahn 4 verteilt. Die Sonotrode 1 schwingt senkrecht zur Ebene der Folienbahn 4.Since the film web 1 due to the inertia of the applied vibration frequency generated acceleration the sonotrode 1 cannot follow, arises over the entire width of the film web 4, a gap 5, which is with the set working frequency of the sonotrode 1 periodically opens. The gap size corresponds approximately the size of the set amplitude A. About the The gap 5 is evenly applied to the film 4 distributed. The sonotrode 1 swings perpendicular to the plane the film web 4.

Die Folienbahn 4 wird über eine Abrundung 6 auf die Sonotrode 1 geführt und über eine Abrißkante 7 von dort abgeleitet. Die Abrundung 6 und die Abrißkante 7 sind hier in die Sonotrode 1 integriert, beide Führungsmittel können jedoch auch separat ausgeführt werden.The film web 4 is rounded to 6 Sonotrode 1 out and over a tear-off edge 7 by derived there. The rounding 6 and the tear-off edge 7 are integrated in the sonotrode 1, both guide means can also run separately become.

Die Abrundung 6 wird mit einem Einlaufwinkel α und die Abrißkante 7 mit einem Auslaufwinkel β gebildet, wobei die Bedingung gilt α < β.The rounding 6 is α and the tear-off edge 7 is formed with an outlet angle β, where the condition applies α <β.

Die Lackmenge wird durch eine nicht dargestellte Dosierpumpe in Abhängigkeit von der Durchlaufgeschwindigkeit der Folienbahn 4 eingestellt, so daß die Lackmenge exakt pro m2 Folienbahn 4 bestimmt ist.The amount of paint is adjusted by a metering pump, not shown, as a function of the throughput speed of the film web 4, so that the amount of paint is determined exactly per m 2 of film web 4.

In der Fig. 2 ist schematisch dargestellt, wie die schwingungsentkoppelte Lackzufuhr über den Kanal 2 in der Sonotrode 1 erfolgen kann. Die Druckluftleitung 3 ist an die Breite der Folienbahn 4 anpaßbar gestaltet.In Fig. 2 is shown schematically how the Vibration-decoupled paint supply via channel 2 in the sonotrode 1 can take place. The compressed air line 3 is designed to be adaptable to the width of the film web 4.

Die Lackzufuhr kann auch durch verstellbare und arretierbare Randabdecksegmente (nicht dargestellt) mit einer Schwingungsentkopplung an den Zuführungsrohren erfolgen anstelle der gezeigten Lackzufuhr durch die Sonotrode 1 hindurch.The paint supply can also be adjusted and lockable edge cover segments (not shown) with a vibration decoupling on the feed pipes take place instead of the paint supply shown through the sonotrode 1.

Zur homogenen Beschichtung einer ebenen Fläche oder einer Materialbahn mit einer Flüssigkeit ist es auch denkbar, die Sonotrode 1 mit den Zuführungen für die Flüssigkeit und dem Andruckmittel zu bewegen. For homogeneous coating of a flat surface or it is also a material web with a liquid conceivable, the sonotrode 1 with the feeds for the Liquid and the pressure medium to move.
