Abstract

The device has two rollers (2, 3) arranged against each other and forming a gap (4) through which a web-like material (1) runs. A trough (5) is formed by the two rollers and two side walls (6, 7) for accommodating a coating mass (8). Two openings (9, 10) are formed in the side walls for transit of the coating mass. The openings are horizontally or vertically arranged in a series or arranged corresponding to dimension of one of the rollers in an arched manner. Height of the coating mass is defined in the trough. Axles of rollers are horizontally arranged.

Description

Die Erfindung betrifft eine Vorrichtung für die Beschichtung von bahnförmigen Materialien umfassend eine erste Walze und eine zweite Walze, die gegeneinander angeordnet sind und einen Spalt bilden, durch den das bahnförmige Material läuft, und einen Trog, der durch die erste Walze, die zweite Walze und zwei Seitenwände gebildet wird, zur Aufnahme einer Beschichtungsmasse.The invention relates to a device for the coating of sheet-like materials comprising a first roller and a second roller, which are arranged against each other and form a gap through which the web-like material passes, and a trough, through the first roller, the second roller and two side walls is formed, for receiving a coating mass.

Eine bekannte Vorrichtung für die Beschichtung besteht aus einer Auftrags- oder Beschichtungswalze und einer Rakel- oder Dosierwalze. Die aufgetragene Menge wird bei dieser Vorrichtung durch den Abstand zwischen den beiden Walzen sowie deren Geschwindigkeiten bestimmt und ist beispielsweise in der DE 39 06070 A1 , speziell Fig 3, Bild c offenbart.A known device for the coating consists of a coating or coating roller and a doctor blade or metering roller. The applied amount is determined in this device by the distance between the two rollers and their speeds and is for example in the DE 39 06070 A1 , especially Fig. 3, picture c discloses.

Ein typisches Anwendungsbeispiel für dieses Walzenauftragsverfahren ist die Herstellung von transdermalen therapeutischen Systemen (TTS). Zu deren Herstellung werden beispielsweise wirkstoffhaltige Lösungen auf Trägerfolien bzw. bahnförmigen Materialien aufgetragen und anschließend weiteren Vorrichtungen wie einem Trockenkanal und/oder Schneidvorrichtungen zugeführt. Andere Anwendungsbeispiele sind die Herstellung von oralen dünnen Filmen oder hochtransparente Beschichtungen, z.B. für die graphische oder elektronische Industrie.A typical application example of this roller application method is the production of transdermal therapeutic systems (TTS). For their preparation, for example, active substance-containing solutions are applied to carrier films or sheet-like materials and then fed to other devices such as a drying channel and / or cutting devices. Other application examples are the preparation of oral thin films or highly transparent coatings, e.g. for the graphic or electronic industry.

Ein Trog zur Aufnahme einer Beschichtungsmasse ist auch beispielsweise aus der DE 16 96 153 bekannt. Dort wird ein Verfahren zum beidseitigen Aufbringen eines Striches auf eine bewegte Papierbahn offenbart, wobei die Papierbahn mittels einer Rakel gegen eine Walzen gedrückt, an der Rakel in einem Winkel von mehr als 5 Grad von der Walze weggebogen wird und zwischen Papierbahn und Rakel ein Streichmassebad gebildet wird.A trough for receiving a coating composition is also for example from the DE 16 96 153 known. There is a method for two-sided application of a Strokes on a moving paper web disclosed, wherein the paper web is pressed by means of a doctor blade against a roll, is bent away at the doctor blade at an angle of more than 5 degrees from the roll and between the paper web and doctor blade a coating compound is formed.

Derartige Vorrichtungen sind auch in DE 38 11 315 C2 und DE 23 14 531 offenbart.Such devices are also in DE 38 11 315 C2 and DE 23 14 531 disclosed.

Die derzeit übliche Praxis die Beschichtungsmassen über Zuführsystem oberhalb des Troges, der durch die gegeneinander stehenden Walzen gebildet wird, einzuleiten, hat je nach reologischen Eigenschaften der Beschichtungsmassen Nachteile, die sich insbesondere in der Gewichtsverteilung des resultierenden Beschichtungsauftrages und in einem inhomogenen Strichbild äußern.The current practice of introducing the coating compositions via the feed system above the trough, which is formed by the rollers standing against each other, has disadvantages, depending on the rheological properties of the coating compositions, which manifest themselves in particular in the weight distribution of the resulting coating application and in an inhomogeneous line pattern.

Im Detail werden die Beschichtungsmassen unter oder über Spiegel eingeleitet, d.h. unterhalb der Oberkante der Beschichtungsmasse oder oberhalb auf die im Trog befindliche Beschichtungsmasse. Für die Einleitung kommen entweder mittig im Auftragswerk angebrachte Rohre / Leitungen oder Vertellersysteme zum Einsatz, aus denen die Beschichtungsmassen mittig einlaufen und dann zum Beispiel durch Prallplatten oder T-Stücke über die Beschichtungsbreite, teilweise mit Hilfe von Dosierschlitzen, im Trog der Vorrichtung bzw. des Auftragswerks verteilt werden.In detail, the coating compositions are introduced under or over mirrors, i. below the upper edge of the coating mass or above on the coating material located in the trough. For the introduction either centrally in the commissioned work tubes / lines or Verteller systems are used, from which the coating masses run in the middle and then, for example, by baffles or tees over the coating width, partially with the help of metering, in the trough of the device or Commissioned work.

Die im Auftragswerk angeordneten Walzen drehen sich typischerweise mit unterschiedlichen Geschwindigkeiten. Eine der beiden Walzen dient als sogenannte Rakelwalze, weil sie gegenläufig gegen das zu beschichtende bahnförmige Material läuft, während die andere Walze, die sogenannte Auftragswalze, sich gleichläufig, d.h. in die gleiche Richtung wie das bahnförmige Material, dreht.The rollers arranged in the applicator typically rotate at different speeds. One of the two rollers serves as a so-called doctor roller, because it runs in opposite directions against the web material to be coated, while the other roller, the so-called application roller, rotates in the same direction, ie in the same direction as the web-shaped material.

Durch die Drehrichtung der Rakelwalze entsteht im Trog eine permanente gegenläufig rotierende Bewegung der Beschichtungsmassen. Diese Rotation wird durch die bekannten Zuführsysteme beeinflusst, die, wie oben beschrieben, über die Breite des Troges an einer oder an mehreren Stelle/-n in die Beschichtungsmasse eintauchen oder an einer oder an mehreren Stelle/-n neue Beschichtungsmasse einbringen. Dabei kann durch die vorhandenen reologischen Eigenschaften das Verhältnis von frisch zufließender Beschichtungsmasse und der bereits im Trog befindlichen Beschichtungsmasse nicht gleichmäßig im Trog verteilt sein. Dafür ist es notwendig den Zufluss der Masse insoweit zuregeln, dass die Menge an zufließender frischer Beschichtungsmasse möglichst gleich dem Verbrauch des Beschichtungsvorganges ist. Dies wird im Allgemeinen durch den Einsatz von Regelventilen bzw. Messsonden, die eventuell vorgeschaltete Fördersysteme regeln, günstig beeinflusst. Weiterhin wird die rollierende Bewegung der Beschichtungsmasse entweder durch die unter dem Spiegel angebrachten Verteilungssysteme oder durch die auf die Oberfläche auflaufende Beschichtungsmasse durchbrochen.Due to the direction of rotation of the doctor roller, a permanent counter-rotating movement of the coating masses arises in the trough. This rotation is influenced by the known delivery systems which, as described above, dive into the coating composition across the width of the trough at one or more locations or introduce new coating material at one or more locations. It can not be evenly distributed in the trough due to the existing rheological properties, the ratio of freshly flowing coating composition and the coating material already in the trough. For this it is necessary to regulate the inflow of the mass to the extent that the amount of incoming fresh coating mass is as equal as possible to the consumption of the coating process. This is generally favorably influenced by the use of control valves or measuring probes, which regulate possibly upstream conveyor systems. Furthermore, the rolling movement of the coating composition is broken either by the distribution systems mounted under the mirror or by the coating material accumulating on the surface.

Bekannte Zuführsysteme unterhalb oder auch oberhalb der Oberkante der Beschichtungsmasse - des Spiegels oder Massespiegels -, die über die Länge des Troges oder auch nur punktuell angeordnet waren, verursachten teilweise ganzflächig ein streifiges Strichbild oder es zeichnete sich bei jeder Massezufuhr optisch inhomogene Flächen auf der beschichteten Bahn ab. Eine ungleichmäßige Gewichtsverteilung über die Bahnbreite wurde ebenfalls festgestellt. Durch die Zuführung über die Länge des Troges oder punktuell von oben war weiterhin eine komplette Abdeckung des Troges nicht möglich.Known feeding systems below or above the upper edge of the coating composition - the mirror or mirror - which were arranged over the length of the trough or even selectively, sometimes caused a stripe-like line pattern over the entire surface or optically inhomogeneous surfaces were formed on the coated web at each mass feed from. Uneven weight distribution across the web width was also noted. Through the supply over the length of the trough or punctually from above a complete coverage of the trough was still not possible.

Bei Einsatz von entflammbaren lösemittelhaltigen Beschichtungsmassen und der dann zu berücksichtigenden Explosions-Schulz-Thematik sind um das Auftragswerk herum geführte permanente Luftströmungen vorgesehen. Diese Luftströmungen gelangen dabei auch auf die Oberfläche der im Trog befindlichen Beschichtungsmasse. Durch die Zuführvorrichtungen kann der Trog nicht vollflächig bzw. voilständig abgedeckt werden, da entsprechende Abdeckungen Durchbrüche für die in den Trog einzufüllende Beschichtungsmasse oder für die Zuführleitungen aufweisen müssen. An den nicht abgedeckten Stellen wird an der Oberfläche der sich im Trog befindlichen Beschichtungsmasse eine Hautbildung begünstigt, weil der auftreffende Luftstrom an diesen nicht abgedeckten Stellen partiell zu einer Verdunstung von in der Beschichtungsmasse vorhandenem Lösungsmittel führt.When using flammable solvent-based coating materials and the then to be considered explosion-Schulz subject matter around the commissioned work around permanent air currents are provided. These Air currents also reach the surface of the coating mass in the trough. By means of the feed devices, the trough can not be covered over the entire surface or completely, since corresponding covers must have openings for the coating mass or the supply lines to be filled into the trough. At the uncovered areas, skinning is favored on the surface of the coating composition in the trough, because the impinging air flow at these uncovered locations leads in part to an evaporation of solvent present in the coating composition.

Der Erfindung liegt daher die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu schaffen, welche die oben beschriebenen Nachteile vermeidet.The invention is therefore an object of the invention to provide a generic device which avoids the disadvantages described above.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass in jeder der Seitenwände mindestens eine Öffnung zur Durchleitung der Beschichtungsmasse ausgebildet ist.This object is achieved in that at least one opening for the passage of the coating composition is formed in each of the side walls.

Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.Embodiments of the invention are specified in the subclaims.

Die Erfindung sieht somit vor, die Beschichtungsmasse seitlich in den Trog einzuleiten. Diese beidseitige Zuführung durch die Seitenwände gewährleistet eine gleichmäßige Einbringung der Beschichtungsmasse in den Trog. Die Rotationsbewegung der Beschichtungsmasse innerhalb der Vorrichtung - des Auftragswerkes - wird nicht durch Einbauten wie Zuleitungen usw. gestört. Daraus ergibt sich eine gleichmäßigere Auftragsgewichtsverteilung sowie ein homogeneres Strichbild.The invention thus provides for introducing the coating material laterally into the trough. This two-sided feed through the side walls ensures a uniform introduction of the coating material in the trough. The rotational movement of the coating material within the device - the commissioned work - is not disturbed by internals such as leads, etc. from that results in a more uniform order weight distribution and a more homogeneous line image.

Zur weiteren Beeinflussung der Zuführung der Beschichtungsmasse können anstelle von einer Öffnung je Seitenwand mehrere Öffnungen pro Seitenwand ausgebildet sein. Diese können horizontal, vertikal oder bogenförmlg eingebracht werden. Hierdurch wird die Zuführung noch gezielter auf die Begebenheiten in der Vorrichtung angepasst.To further influence the feeding of the coating composition, instead of one opening per side wall, a plurality of openings per side wall may be formed. These can be placed horizontally, vertically or arcuately. As a result, the feed is adapted even more targeted to the events in the device.

Beim Einsatz der seitlichen Beschichtungsmassenzufuhr wird ein gleichmäßige Beschichtungsbild mit stark verringerten Strukturen und Streifen erzeugt. Weiterhin kann der Trog an seiner Oberseite komplett abgedeckt werden. Hierdurch wird die Abdunsfiung / Verdunstung des in der Beschichtungsmasse vorhandenen Lösungsmittels bzw. der vorhandenen Lösungsmittel wesentlich verringert.The use of lateral coating material feed produces a uniform coating pattern with greatly reduced textures and streaks. Furthermore, the trough can be completely covered on its top. As a result, the Abdunsfiung / evaporation of the existing solvent in the coating composition or the existing solvent is substantially reduced.

Die bei vorhandenen Vorrichtungen oberhalb des Troges angeordneten Zuleitungsrohre für die Beschichtungsmasse können weiterhin genutzt werden. Diese Zuleitungen erhalten ein zusätzliches T-förmiges Verteilrohr welches über zwei gleichförmige Verteilschläuche mit Schlauchverbindungsstücken verbunden wird, die in den Seitenwänden münden und eine Zuführung der Beschichtungsmasse unterhalb des Massespiegels bei gefülltem Trog vorsieht.The existing at devices above the trough supply pipes for the coating material can continue to be used. These supply lines receive an additional T-shaped distribution pipe which is connected via two uniform distribution hoses with hose connectors, which open in the side walls and provides a supply of the coating material below the level of mass with a filled trough.
