Abstract

The sheet material (4) to be coated is fed over the surface of an ultrasound-vibration system (1). The vibration system produces a periodically opening gap (5) between the sheet material and the upper surface of the vibration system. The opening gap is timed with the applied work frequency, and the fluid is applied onto the sheet material through the gap. The sheet material to be coated is pressed by compressed air or an elastic co-rotating roller, onto the ultrasound vibration system. The fluid is applied through the ultrasound vibration system onto the material and the amount of fluid is exactly adjusted by a controlled feed pump, depending upon the throughflow speed of the sheet material.

Description

Die Erfindung bezieht sich auf ein Verfahren zum dosierten Aufbringen von Flüssigkeiten auf Material­ bahnen, insbesondere auf Folien gemäß dem Oberbegriff des Anspruches 1.The invention relates to a method for dosed application of liquids to material webs, especially on foils according to the preamble of claim 1.

Bekannte Verfahren in der Druckindustrie verwenden, insbesondere beim Offset- oder beim Tiefdruck, zum Aufbringen der Druckflüssigkeit Walzenwerke. Use known processes in the printing industry especially in offset or gravure printing Application of the hydraulic fluid roller mills.  

Des weiteren sind zum Beschichten von ebenen Trägerschichten allgemeine Sprühverfahren bekannt.They are also used for coating planes Carrier layers known general spraying methods.

Nachteilig ist es bei der Anwendung des bekannten Standes der Technik zum Beispiel in der Druck­ industrie, 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 Walzen­ werken und in den Wannen und ein großer Verschleiß der Walzenwerke auf.It is disadvantageous when using the known State of the art for example in printing industry that expensive equipment is needed and a high cleaning effort of the printing unit is necessary is, for example, if there is a color change should. There are high material losses in the rollers work and in the tubs and a great wear of the Roller mills.

Sprühverfahren weisen insbesondere den Nachteil einer ungleichmäßigen Beschichtung und einer hohen Umwelt­ belastung durch das offene System auf.Spray processes have the disadvantage of one in particular uneven coating and a high environment load 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 sound system takes place on the free surface of the web of material a spaced horn. This procedure is ineffective since the impact of the sound waves over the air does not produce the desired effect dosed application of liquids.

Es ist daher Aufgabe der vorliegenden Erfindung, diese Nachteile zu beseitigen und ein Verfahren zum dosierten Aufbringen von Flüssigkeiten auf Material­ bahnen zu entwickeln, mit dem eine homogene Beschich­ tung und eine minimale Umweltbelastung gewährleistet sind. It is therefore an object of the present invention To eliminate disadvantages and a method for dosed application of liquids to material to develop webs with a homogeneous coating guarantee and a minimal environmental impact are.  

Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruches 1.The solution to this problem arises from the Features of claim 1.

Durch die direkte Anwendung von Ultraschall wird ein Verfahren aufgezeigt, mit dem eine gleichmäßige Dosierung und eine homogene Beschichtung gewährleistet werden und mit dem infolge des geschlossenen Systems und der damit verbundenen geringen Materialverluste keine oder eine geringfügige Umweltbelastung besteht. Through the direct application of ultrasound, a Process demonstrated using a uniform Dosage and a homogeneous coating guaranteed and with that as a result of the closed system and the associated low material losses there is no or a minor environmental impact.  

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further advantageous embodiments of the invention result from the subclaims.

Die Erfindung ist nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispieles einer Vorrichtung zur Durchführung des Verfahrens näher erläutert. Es zeigen:The invention is based on one in the Drawing shown embodiment of a Device for performing the method closer explained. Show it:

Fig. 1 eine Prinzipdarstellung der Vorrichtung zur Durchführung des Verfahrens nach der Erfindung in Schnittdarstellung und Fig. 1 is a schematic representation of the device for performing the method according to the invention in a sectional view and

Fig. 2 die schematische Seitenansicht in Teilschnittdarstellung der Vorrichtung nach Fig. 1 (teilweise). Fig. 2 shows the schematic side view in partial section of the device according to Fig. 1 (partially).

Die Vorrichtung nach den Fig. 1 und 2 wird aus einem Ultraschall-Schwingungssystem (Sonotrode) 1 gebildet, in welchem 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.The device according to FIGS. 1 and 2 is formed from an ultrasonic vibration system (sonotrode) 1 , in which a feed 2 for a liquid, here for example for a lacquer, is provided. An air duct 3 for introducing compressed air is arranged above the sonotrode 1 .

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, here for example a film web 4 , is guided over the surface of the sonotrode 1 ( FIG. 1).

Die Sonotrode 1 besteht aus einer Ultraschall-Leiste, die beispielsweise aus einer Vielzahl parallel arbeitender Schallwandler aufgebaut ist, welche gemeinsam den Schwigungsbalken phasengleich anregen, aber voneinander gegen Querschwingen entkoppelt sind.The sonotrode 1 consists of an ultrasound bar, which is constructed, for example, from a plurality of sound transducers working in parallel, which together excite the oscillation beam in phase, but are decoupled from one another against transverse vibrations.

Die Sonotrode 1 schwingt über die gesamte Arbeits­ breite 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 phase position.

Die zu beschichtende Folienbahn 4 wird mittels des mit Überdruck beauflagten Luftschachtes 3 auf die Ober­ fläche 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 Andruck­ kraft erreicht werden.The film web 4 to be coated is pressed onto the upper surface of the sonotrode 1 by means of the pressurized air shaft 3 . Instead of compressed air, an elastically rotating roller or a similar means can also be used to guide the film 4 over the sonotrode 1 with a defined pressure force. It can also be achieved by the choice of film web tension, the necessary pressure force.

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 can not follow the acceleration due to inertia generated by the applied vibration frequency of the sonotrode 1, is formed over the entire width of the film web 4, a gap 5, which periodically opens at the set operating frequency of the horn. 1 The gap size corresponds approximately to the size of the set amplitude A. Via the gap 5 , the lacquer is evenly distributed over the film web 4 . The sonotrode 1 swings perpendicular to the plane of 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 Füh­ rungsmittel können jedoch auch separat ausgeführt werden.The film web 4 is guided over a rounding 6 onto the sonotrode 1 and derived from there via a tear-off edge 7 . The rounding 6 and the tear-off edge 7 are integrated here in the sonotrode 1 , but both guide means can also be carried out separately.

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 formed with an entry angle α and the tear-off edge 7 with an exit angle β, the condition being α <β.

Die Lackmenge wird durch eine nicht dargestellte Dosierpumpe in Abhängigkeit von der Durchlaufge­ schwindigkeit 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, depending on the speed of the sheet 4 , so that the amount of paint is determined per m² of sheet 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. FIG. 2 shows schematically how the vibration-decoupled paint supply can take place via the channel 2 in the sonotrode 1 . 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 Zuführungs­ rohren erfolgen anstelle der gezeigten Lackzufuhr durch die Sonotrode 1 hindurch.The paint supply can also be done by adjustable and lockable edge cover segments (not shown) with a vibration decoupling on the feed pipes 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 the homogeneous coating of a flat surface or a material web with a liquid, it is also conceivable to move the sonotrode 1 with the feeds for the liquid and the pressure medium.
