Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum kontinuierlichen Beschichten eines vorwärts bewegten Bahnmaterials mit einem viskosen Medium, insbesondere einem lösemittelhaltigen Lack oder mit einer Klebstofflösung. Die Erfindung bezieht sich insbesondere auf eine Vorrichtung die für das sogenannte "Auffliessen" geeignet ist.The invention relates to a method and an apparatus for the continuous coating of a moving web material with a viscous medium, in particular a solvent-based paint or with an adhesive solution. The invention relates in particular to a device which is suitable for so-called "flow-up".

Aus der DE 25 07 116 ist eine Vorrichtung und ein Verfahren mit einem horizontal angeordneten Mehrwalzen-Auftragswerk und einem in Wirkverbindung stehenden horizontalen Vorratsbehälter bekannt, wobei eine erste Dosierung des Auftragsmediums in einem vertikalen NIP-Walzenspalt mit den horizontal angeordneten in Wirkverbindung stehenden drehbaren Walzen erfolgt.From the DE 25 07 116 a device and a method with a horizontally arranged Mehrwalzen applicator and an operatively connected horizontal reservoir is known, wherein a first metering of the application medium takes place in a vertical NIP nip with the horizontally arranged rotatable rollers operatively connected.

Eine weitere Beschichtungsvorrichtung mit einem vertikal angeordneten NIP-Walzenspalt ist aus der DE 39 06 070 , Figur 3, bekannt.Another coating apparatus with a vertically arranged NIP nip is known from US 5,478,237 DE 39 06 070 , Figure 3, known.

Eine Einrichtung zum Auftragen einer Beschichtungsflüssigkeit auf eine sich bewegende Bahn mit einer in einem Gestell drehbar angeordneten Auftragswalze, einer in Wirkverbindung dazu vertikal angeordneter Vorratskammer für das Beschichtungsmedium und einem Dosierrakel ist aus DE 28 20 249 bekannt.A device for applying a coating liquid to a moving web with a applicator roll rotatably arranged in a frame, a storage chamber for the coating medium arranged vertically in connection therewith and a metering doctor is eliminated DE 28 20 249 known.

Mit den geforderten erhöhten Beschichtungsgeschwindigkeiten hat sich bei den aus dem Stand der Technik bekannten Auftragswerken die Schaumbildung im Auftragswerk, insbesondere im Vorratsbereich des Beschichtungsmediums, als nachteilig erwiesen. Verursacht wird die Schaumbildung durch Lufteinschlüsse durch die erhöhte Umfangsgeschwindigkeit der Auftragswalzen im Auftragsmedium. Die Schaumbildung ist auf dem Beschichtungssubstrat nachteilig als Lufteinschlüsse visuell wahrnehmbar. Weiter ist die Schaumbildung hinderlich beim Regeln des Volumenstroms für das Auftragmedium. Weitere Nachteile der Schaumbildung werden in der DE 28 20 249 beschrieben.With the required increased coating speeds, foaming in the application unit, in particular in the storage area of the coating medium, has proven to be disadvantageous in the case of the application units known from the prior art. Foam formation is caused by air pockets due to the increased peripheral speed of the applicator rollers in the application medium. The foaming is adversely visibly perceptible as air pockets on the coating substrate. Furthermore, foaming is a hindrance in controlling the volume flow for the application medium. Other disadvantages of foam formation are in the DE 28 20 249 described.

Aus der DE 39 24 273 ist eine Leimauftragsvorrichtung mit einer Leimwanne, einer Leimauftragswalze und einer Dosierwalze. Diese beiden Walzen bilden zusammen einen Dosierspalt für den in der Leimwanne befindlichen Leim. Dabei taucht der Oberflächenbereich der Dosierwalze in die Leimwanne ein und kann mit Leim beaufschlagt werden. Die US 4,538,541 beschreibt eine Vorrichtung und ein Verfahren zum Auftragen einer gleichförmigen Flüssigkeitsschicht auf eine Oberfläche. Die Vorrichtung kann zwei Auftragswalzen aufweisen, die miteinander einen NIP-Walzenspalt bilden, der zur Regelung der Auftragsmenge verstellt werden kann.From the DE 39 24 273 is a glue application device with a glue trough, a glue applicator roller and a metering roller. These two rollers together form a metering gap for the glue in the glue trough. The surface area of the metering roller dips into the glue trough and can be exposed to glue. The US 4,538,541 describes an apparatus and method for applying a uniform layer of liquid to a surface. The apparatus may comprise two applicator rollers which together form an NIP nip which can be adjusted to control the amount applied.

Aufgabe der Erfindung ist es, eine Vorrichtung und ein Verfahren zum gleichmäßigen Auftragen eines viskosen Auftragsmediums, insbesondere lösungsmittelhaltige Lacke oder Klebstoffe, auf ein sich bewegendes Trägermaterial zu schaffen, mit denen die Schaumbildung durch Lufteinschlüsse verhindert wird.The object of the invention is to provide a device and a method for uniform application of a viscous coating medium, in particular solvent-containing paints or adhesives, on a moving support material with which the foaming is prevented by air pockets.

Die erfindungsgemäße Vorrichtung besteht aus einer Vorratskammer für das aufzutragende Mittel und wenigstens zwei Walzen, bevorzugt genau zwei Walzen, mit im Wesentlichen parallel verlaufenden Rotationsachsen, wobei die Walzen in die Vorratskammer hineinreichen und zwischen zumindest zwei benachbarten Walzen einen Walzenspalt, bevorzugt einen NIP-Walzenspalt bilden. Der NIP-Walzenspalt unterscheidet sich von einem normalen Walzenspalt dadurch, dass die Größe des Spaltes, gebildet durch den kleinsten Abstand der beiden Oberflächen zweier Walzen zueinander, einstellbar ist. Dies kann dadurch geschehen, dass zum Beispiel eine der Walzen oder zwei bzw. mehrere Walzen verstellbar ist/sind, so dass sich der Abstand zwischen den Rotationsachsen der Walzen verändert.The inventive device consists of a storage chamber for the agent to be applied and at least two rollers, preferably exactly two rollers, with substantially parallel axes of rotation, wherein the rollers extend into the storage chamber and between at least two adjacent rollers form a nip, preferably a NIP nip , The NIP nip differs from a normal nip in that the size of the nip formed by the smallest distance between the two surfaces of two rolls is adjustable. This can be done by, for example, one of the rollers or two or more rollers being adjustable, so that the distance between the axes of rotation of the rollers changes.

Wenigsten eine, bevorzugt alle Walzen sind drehangetrieben. Dabei können die Walzen über einen gemeinsamen Antrieb verfügen oder je einzeln von einem z.B. Elektromotor angetrieben werden, wodurch jede der wenigstens zwei Walzen sich mit einer anderen Geschwindigkeit drehen kann, als jede der anderen. Die Drehrichtung der Walzen kann gleichgerichtet sein, bevorzugt wird allerdings, dass die zwei Walzen, die miteinander den NIP-Walzenspalt bilden, gegenläufig drehen. Die Drehrichtungen sind dabei so gewählt, dass beide den NIP-Walzenspalt bildenden Walzen das Beschichtungsmaterial aus einer Vorratskammer in den NIP-Walzenspalt transportieren. Bevorzugterweise ist dabei eine der beiden Walzen eine Gummiwalze, die andere eine Stahlwalze. Grundsätzlich soll aber nicht ausgeschlossen sein, dass beide Walzen Gummi- bzw. Stahlwalzen oder andere geeignete Walzen sind. Die Rotationsachsen der Walzen liegen in einer bevorzugten Ausführung auf einer Geraden, die weitestgehend senkrecht zu der zu beschichtenden Bahn in dem Bereich steht, wo die Beschichtung stattfindet. Dadurch ergibt sich eine Anordnung der Vorratskammer seitlich der Walzen, sowie eine weitestgehend horizontale Ausrichtung des NIP-Walzenspalts.At least one, preferably all rollers are rotationally driven. In this case, the rollers may have a common drive or be driven individually by an electric motor, for example, whereby each of the at least two rollers can rotate at a different speed than each of the other. The direction of rotation of the rolls may be rectified, but it is preferred that the two rolls forming the NIP nip together rotate in opposite directions. The directions of rotation are chosen so that both rollers forming the NIP nip transport the coating material from a storage chamber into the NIP nip. Preferably, one of the two rollers is a rubber roller, the other a steel roller. In principle, however, it should not be ruled out that both rolls are rubber or steel rolls or other suitable rolls. The axes of rotation of the rollers lie in a preferred embodiment on a straight line which is largely perpendicular to the web to be coated in the area where the coating takes place. This results in an arrangement of the storage chamber side of the rollers, as well as a largely horizontal orientation of the NIP roller gap.

Die stehende vertikal angeordnete Vorratskammer wird auf der einen Längsseite, das heißt der Seite, deren Erstreckung in die Richtung der Geraden verläuft, auf der die Rotationsachsen der Walzen liegen, durch die Walzen, auf der anderen Längsseite durch eine Rückwand, z.B. aus Metall gebildet. Die Kammer weist außerdem Seitenwände, sowie die Ober- und Unterseite der Kammer bildende Wände auf. Die Längserstreckung der Vorratskammer ist kürzer als der Abstand zwischen dem Punkt auf der obersten Walze, in dem die, durch die Rotationsachsen der Walzen gebildete Gerade diese nach oben durchbricht, und dem Punkt auf der untersten Walze, in dem die, durch die Rotationsachsen gebildete Gerade diese nach unten durchbricht. Das heißt mit anderen Worten, die oberste Walze und die unterste Walze stehen in Längsrichtung gesehen über die Vorratskammer hinaus. In einer weniger bevorzugten Ausführungsform kann der Vorratsbehälter auch über die obere und/oder untere Walze hinausragen oder die gleiche vertikale Erstreckung haben, wie die Gesamtheit der Walzen. Die durch die Rotationsachsen gebildete Gerade kann natürlich auch einen beliebigen Neigungswinkel zur Trägerbahn in Bereich der Beschichtung aufweisen, im Extremfall kann sie horizontal angeordnet sein. Im letzteren Fall wäre der NIP-Walzenspalt dann ein vertikaler Spalt und die Vorratskammer wäre oberhalb oder unterhalb der Walzen angeordnet.The standing vertically arranged storage chamber is on the one longitudinal side, that is, the side whose extension extends in the direction of the straight line on which the axes of rotation of the rollers lie, through the rollers, on the other longitudinal side by a rear wall, e.g. made of metal. The chamber also has side walls as well as the top and bottom of the chamber forming walls. The longitudinal extent of the storage chamber is shorter than the distance between the point on the uppermost roll in which the straight line formed by the axes of rotation of the rolls breaks upwards and the point on the lowermost roll in which the straight line formed by the axes of rotation breaks them down. In other words, the top roller and the bottom roller are seen in the longitudinal direction beyond the pantry. In a less preferred embodiment, the reservoir can also protrude beyond the upper and / or lower roll or have the same vertical extent as the entirety of the rolls. Of course, the straight line formed by the axes of rotation can also have an arbitrary angle of inclination to the carrier web in the region of the coating; in an extreme case, it can be arranged horizontally. In the latter case, the NIP nip would then be a vertical gap and the storage chamber would be located above or below the rollers.

Die seitliche Ausdehnung der Vorratskammer, gemeint ist die Ausdehnung in Richtung der Längsachse der Walzen, ist einstellbar. Dadurch kann Trägermaterial verschiedener Breite beschichtet werden, bzw. können verschieden breite Streifen von Beschichtungsmaterial auf ein Trägermaterial aufgebracht werden. Sollen mehrere Streifen von Beschichtungsmaterial nebeneinander auf das Trägermaterial aufgebracht werden, können entweder mehrere schmale Vorratskammern entlang der Zylinder nebeneinander angeordnet sein, oder die Vorratskammer ist in Querrichtung, das heißt entlang der Längsachse der Walzen, in Bereiche unterteilbar, die wahlweise alle oder einzeln mit Beschichtungsmaterial beschickt werden können. Zur Abdichtung weisen die Seitenwände der Vorratskammer zum Beispiel elastische Dichtungen auf, die sie im Bereich der Walzen abdichten. In Richtung der Walzenlängsachse ist die Vorratskammer an der obersten und der untersten Walze mittels zum Beispiel ebenfalls elastischer Dichtungen oder Rakeln abgedichtetThe lateral extent of the storage chamber, meaning the extension in the direction of the longitudinal axis of the rollers, is adjustable. As a result, carrier material of different widths can be coated, or different widths of coating material can be applied to a carrier material. If a plurality of strips of coating material are to be applied next to one another onto the carrier material, either a plurality of narrow storage chambers can be arranged alongside one another along the cylinders, or the storage chamber can be arranged transversely, that is to say along the Longitudinal axis of the rollers, subdivided into areas that can be fed either all or individually with coating material. For sealing, the side walls of the storage chamber, for example, on elastic seals, which seal them in the area of the rollers. In the direction of the roller longitudinal axis, the storage chamber is sealed to the uppermost and the lowermost roller by means of, for example, likewise elastic seals or doctor blades

Das Beschichtungsmaterial wird in die Vorratskammer durch wenigstens einen Einlass zugeführt und durch wenigstens einen Überlauf wieder aus der Vorratskammer befördert. Bevorzugterweise wird dabei das Beschichtungsmaterial kontinuierlich in einer Menge zugeführt, die über der zur Beschichtung benötigten Menge liegt. Ist der Einlass bzw. sind die Einlässe dabei, wie bevorzugt, an oder nahe dem unteren Ende der Vorratskammer angebracht, der Auslass bzw. die Auslässe dagegen am obersten Ende der Vorratskammer, ist die Vorratskammer immer mit Beschichtungsmaterial gefüllt, wodurch die Gefahr von Lufteinschlüssen im Beschichtungsmaterial vermindert wird. Das durch den Überlauf strömende Beschichtungsmaterial wird vorzugsweise aufgefangen und dem Prozess wieder zugeführt.The coating material is fed into the storage chamber through at least one inlet and conveyed out of the storage chamber by at least one overflow. Preferably, the coating material is continuously supplied in an amount which is above the amount required for coating. If the inlet or the inlets are, as preferred, attached to or near the lower end of the storage chamber, the outlet or the outlets on the other hand, at the uppermost end of the storage chamber, the storage chamber is always filled with coating material, whereby the risk of air inclusions Coating material is reduced. The coating material flowing through the overflow is preferably collected and returned to the process.

Zur Übertragung des Beschichtungsmaterials auf das Trägermaterial bildet die oberste der Auftragswalzen mit einer zum Beispiel Gummiwalze, die das Trägermaterial durch die Maschine transportiert, einen weiteren NIP-Walzenspalt. In diesem weiteren NIP-Walzenspalt läuft das Trägermaterial und wird durch die Auftragswalze mit dem Beschichtungsmaterial beschichtet. Zwischen dem NIP-Walzenspalt zur Dosierung des Beschichtungsmaterials und dem weiteren NIP-Walzenspalt ist auf der, der Vorratskammer abgewandten Seite der obersten Auftragswalze eine Rakel angestellt um sicher Lufteinschlüsse im Beschichtungsmaterial zu verhindern.To transfer the coating material to the carrier material, the uppermost of the applicator rolls with a rubber roller, for example, which transports the carrier material through the machine, forms a further NIP nip. In this further NIP nip runs the carrier material and is coated by the applicator roll with the coating material. Between the NIP nip for metering the coating material and the other NIP nip is on the side facing away from the storage chamber side of the top application roller employed a squeegee to safely prevent air pockets in the coating material.

Die Vorratskammer kann abhängig davon, ob es sich um eine Gegenlauf- oder Mitlaufbeschichtung handelt an der einen oder anderen Seite der Auftragswalzen angebracht sein. Unter Gegenlaufbeschichtung versteht man eine Beschichtung des Trägermaterials, bei dem die Auftragswalze entgegen dem Bahnlauf dreht, während im Falle der Mitlaufbeschichtung die Auftragswalze in Richtung des Bahnlaufs dreht.The pantry can be mounted on one side or the other of the applicator rollers, depending on whether it is a countercurrent or countercurrent coating. Countercurrent coating is understood to mean a coating of the carrier material in which the applicator roll rotates counter to the web run, while in the case of the follower coating the applicator roll rotates in the direction of the web run.

Gelöst wird die Aufgabe mit einem Auftragswerk (1; 2) mit horizontalem NIP-Walzenspalt (3.1; 3.2) für die Dosierung des Auftragmediums und einer in Wirkverbindung stehender vertikal angeordneter Vorratskammer (4.1; 4.2) gemäß den Figuren 1; 2. Der horizontale NIP-Walzenspalt (3.1; 3.2) wird zwischen den Auftragswalzen (W1) und (W2) gebildet. In Abhängigkeit einer Gegenlauf- (Fig. 1) oder Mitlauf-Beschichtung (Fig. 2) kann die vertikale Vorratskammer zu der einen oder der anderen Seite der Auftragswalzen (W1, W2) angeordnet werden. Im Gegenlaufverfahren (Fig. 1, Drehrichtung der Walze W2 entgegen dem Bahnlauf) ist in Abhängigkeit der Eigenschaften des Auftragmediums ein Auftragsgewicht zwischen 8 bis 30 und im Mitlaufverfahren (Fig.2) zwischen 3 bis 12 g/m2 nass vorgesehen. Die Umfangsgeschwindigkeit der Gummiwalze (W3) entspricht der Bahngeschwindigkeit, bis etwa 450 m/min. Die Umfangsgeschwindigkeit der Stahlwalze (W2) ist regelbarer von etwa 30 bis 200 % und die Umfangsgeschwindigkeit der Gummiwalze (W1) etwa 5 bis 50 % der Bahngeschwindigkeit. Zur Feineinstellung der Auftragsmenge sind die Umfangsgeschwindigkeiten der Walzen (W1, W2) zueinander verstellbar. Das Zuführvolumen des Auftragmediums zu der Vorratskammer beträgt etwa das 1.5-flache des Verbrauchsvolumens.The object is achieved with a commissioned work (1; 2) with horizontal NIP nip (3.1; 3.2) for the metering of the application medium and a vertically arranged supply chamber (4.1; 4.2) in operative connection according to FIGS Figures 1; 2 , The horizontal NIP nip (3.1; 3.2) is formed between the applicator rolls (W1) and (W2). Depending on a mating ( Fig. 1 ) or tracking coating ( Fig. 2 ), the vertical storage chamber may be arranged to one side or the other of the applicator rollers (W1, W2). In the opposite process ( Fig. 1 , Direction of rotation of the roller W2 against the web run), depending on the properties of the application medium, an order weight between 8 to 30 and in the follow-on process ( Fig.2 ) between 3 to 12 g / m2 wet. The peripheral speed of the rubber roller (W3) corresponds to the web speed, up to about 450 m / min. The peripheral speed of the steel roller (W2) is more controllable from about 30 to 200% and the peripheral speed of the rubber roller (W1) is about 5 to 50% of the web speed. For fine adjustment of the order amount, the peripheral speeds of the rollers (W1, W2) are mutually adjustable. The supply volume of the application medium to the storage chamber is about the 1.5-flat of the consumption volume.

Die Zuführung des Auftragmediums in die Vorratskammer erfolgt etwa horizontal über eine geeignete Zuführleitung am unteren Ende der Vorratskammer. Der Stromverlauf des Auftragmediums in der Vorratskammer ist vertikal von unten noch oben.The supply of the application medium into the storage chamber takes place approximately horizontally via a suitable supply line at the lower end of the storage chamber. The current flow of the application medium in the pantry is vertically from below still up.

Das Beschichtungsmedium auf die Bahn (S) wird im NIP-Walzenspalt zwischen der Walze (W2) und der Walze (W3) übertragen.The coating medium on the web (S) is transferred in the NIP nip between the roll (W2) and the roll (W3).

Die sich gegenläufig drehenden Auftragwalzen (W1, W2) fördern das Auftragsmedium horizontal in den NIP-Walzenspalt. Zur Einstellung der Auftragsmenge sind die Walzen (W1, W2) vertikal zueinander verstellbar. Der Abstand der hinteren vertikalen Abschlusswand der Vorratskammer ist zu den Auftragswalzen (W1, W2) und den Seitenwänden horizontal verstellbar, so dass Volumen in der Vorratskammer geändert werden kann. Zum Abdichten der Vorratskammer (4.1, 4.2) ist am unteren Ende in Wirkverbindung mit der Walze (W1) ein geeignetes Rakel, zum Beispiel ein Messerrakel, vorgesehen. Seitlich, etwa der Beschichtungsbreite entsprechend, ist die Vorratskammer in Wirkverbindung mit den Walzen (W1, W2) mit Seitenwänden abgeschlossen. Für Unterhaltsarbeiten am Auftragswerk (1) lässt sich die gesamte Vorratskammer mit geeigneten Mitteln von den Walzen (W1, W2) wegbewegen.The counter rotating applicator rollers (W1, W2) convey the application medium horizontally into the NIP nip. To set the order quantity, the rollers (W1, W2) are vertically adjustable. The distance of the rear vertical end wall of the storage chamber is horizontally adjustable to the applicator rollers (W1, W2) and the side walls, so that changed volume in the pantry can be. For sealing the storage chamber (4.1, 4.2) is at the lower end in operative connection with the roller (W1), a suitable doctor blade, for example a knife blade provided. Laterally, corresponding approximately to the coating width, the storage chamber is closed in operative connection with the rollers (W1, W2) with side walls. For maintenance work on the commissioned work (1), the entire storage chamber can be moved away from the rollers (W1, W2) by suitable means.

An dem oberen Ende der Vorratskammer (4.1, 4.2) ist ein Überlauf (9) gebildet, über den der im Überschuss zugeführte Volumenstrom an die Rückwand der Vorratskammer abfließen kann. Eine Auffangvorrichtung (5) mit einem Abfluss (6) unterhalb des Auftragwerks (1; 2) nimmt das im Überschuss zugeführte Auftragmedium auf. Zum Schutz des Auftragmediums kann über die vertikale Vorratskammerwand eine äußere Abdeckung angeordnet sein.At the upper end of the storage chamber (4.1, 4.2), an overflow (9) is formed, via which the volume flow supplied in excess can flow to the rear wall of the storage chamber. A collecting device (5) with an outflow (6) below the applicator (1; 2) picks up the application medium supplied in excess. To protect the application medium can be arranged over the vertical pantry wall, an outer cover.

An die den Spalt für das Trägermaterial (S) mitbildenden Auftragswalze (W2) ist auf der von der Vorratskammer (4.1; 4.2) abgewandten Seite ein Rakel (10) angestellt, um noch sicherer Lufteinschlüsse im Beschichtungsmaterial (7) zu verhindern.A doctor blade (10) is set against the applicator roller (W2) forming the gap for the carrier material (S) on the side facing away from the storage chamber (4.1; 4.2) in order to prevent even more sure air inclusions in the coating material (7).
