Definitions
- the invention relates to a nozzle-like coating device according to the preamble of claim 1.
- Such a coating device has become known from DE-A-3 446 757. It is a matter of removing the comparatively large excess quantities from the nozzle space without air being drawn in in the region of the overflow bar.
- the invention is therefore based on the object of designing a coating device in accordance with the preamble of claim 1 in such a way that the entire device is as compact as possible, i.e. is designed to be as space-saving as possible, furthermore that the technological requirements for such a nozzle coating device are largely met, in particular with regard to the uniformity of the coat application, and that the coating device is ultimately as simple as possible in construction.
- the coating device is cleverly arranged into a compact unit that takes up as little space as possible, but nevertheless fulfills the functions placed on it perfectly.
- the nozzle-like coating device shown in FIG. 1 has a nozzle space 3. This is limited in the web running direction by an overflow bar 4 on the inlet side and a metering bar 5.
- Spreading material is fed to a distribution pipe 6.
- the distribution pipe 6 has a plurality of outlet openings, not shown here, which are in conductive connection with a feed channel 7, so that coating slip passes through the channel 7 to the nozzle space 3 and thus to the paper web 1.
- Halfway up the feed channel there are stumbling thresholds 7.1, which generate microturbulence in the coating slip.
- a discharge channel 8 establishes a conductive connection with an overflow channel 9.
- At the end of the discharge channel 8 there is an adjustable valve 10 for controlling the overflow quantity.
- a device 11 serves to regulate the deflection compensation.
- the compensation device 11 is designed in the present case according to DE-A-39 25 517. It has a fixed yoke 12, a sleeve 13 which surrounds the yoke 12 and pressure transmission elements 14, in the present case air bellows. When the air bellows 14 are charged with compressed air, the position of the sleeve 13 and thus also that of the metering bar 5 is changed, so that deflection compensation is produced.
- the compensation device 11 can be designed and arranged in such a way that a sufficiently large "inner stroke" is created in order to also set the width of the gap between the edge of the metering strip 5 and the paper web 1. This means that no further facility is required.
- a laser measuring device 15 is provided with which the exact position of the edge of the metering bar 5 can be detected. A signal obtained from this is used to control the compensation device 11.
- the entire coating device can be structurally separated in such a way that the compensation device 11 acts solely on the metering strip 5.
- the coating device can however, they can also be designed so that the compensation device 11 acts on the entire coating device and optionally corrects its deflection, or its distance from the paper web 1.
- discharge channel 8 runs through the entire coating device essentially in a diagonal direction, starting from the edge of metering bar 5 to overflow channel 9.
- the overflow gutter 9 also serves to collect the very large excess from channel 8, as well as the very small overflow that comes from the overflow bar 4. As can be seen, there is a flow body 16 between the supply duct 7 and the discharge duct 8. This is therefore essentially limited by the supply duct 7, the nozzle chamber 3 and the discharge duct 8.
- the entire coating device is designed as a compact structural unit, which is essentially bar-shaped, and in which all functionally important elements are combined.
- the following elements are copied around an imaginary center point: distribution pipe 6, flow body 16, laser measuring device 15, compensation device 11 and overflow channel 9.
- the coating slip has a clear flow direction at every point, that no current crossings occur, and that - except for a small partial flow on the overflow bar 4 - it only flows in the direction of travel when it comes into contact with the paper web. This fulfills an important prerequisite for a clean, high-quality line, regardless of whether the device is used as a pre-metering device or as the only coating device.
- the coating device shown in FIG. 2 also follows the same principles as that according to FIG. 1.
- the elements distribution pipe 6, flow body 16 and compensation device 11 are arranged one behind the other in the web running direction.
- Inlet channel 7 connects distribution pipe 6 to nozzle space 3. It takes a course essentially perpendicular to paper web 1.
- Discharge channel 8 with valve 10 in turn opens on the inlet side of the coating device, ie where the paper web 1 arrives.
- the coating slip thus rises upwards from the distribution pipe in the inlet channel 7, is thereby set to a certain, desired turbulence by trip hazards 7.1, then flows in its main quantity past the discharge channel 8, a smaller subset reaching the discharge channel, continues to reach the nozzle chamber 3. where a smaller part remains on the paper web and emerges through the gap between paper web 1 and overflow bar 5, while the larger part of the coating slip flows completely around the flow body 16 and reaches the discharge channel 8.

Description
Die Erfindung betrifft eine düsenartige Streicheinrichtung gemäß dem Oberbegriff von Anspruch 1.The invention relates to a nozzle-like coating device according to the preamble of claim 1.
Eine solche Streicheinrichtung ist aus DE-A-3 446 757 bekannt geworden. Dabei geht es darum, die vergleichsweise großen Überschußmengen aus dem Düsenraum abzuführen, ohne daß es zum Einziehen von Luft im Bereich der Überlaufleiste kommt.Such a coating device has become known from DE-A-3 446 757. It is a matter of removing the comparatively large excess quantities from the nozzle space without air being drawn in in the region of the overflow bar.

Die Raumverhältnisse sind im allgemeinen beengt. Daher besteht generell das Bedürfnis, Streicheinrichtungen gemäß der eingangs genannten Art möglichst kompakt zu gestalten. Gleichzeitig sind jedoch gewisse technologische Anforderungen zu erfüllen. So sollen beispielsweise die Vorzüge gemäß der Lehre von (1) erhalten bleiben, d.h. ein sogenanntes Skip Coating vermieden werden, d.h. ein Streichen, bei der von Streichmasse völlig unbedeckte Stellen infolge Luftblasen auftreten können. Außerdem soll zu jedem Zeitpunkt ein stets gleichbleibender Spalt im Bereich der Überlaufleiste herrschen, und es soll die Spaltweite gemäß der Lehre von (1) möglichst gering gehalten werden, so daß jedenfalls an dieser Stelle ein ganz kleiner oder überhaupt kein Überlauf vorhanden ist.The space is generally cramped. Therefore, there is generally a need to make coating devices as compact as possible in accordance with the type mentioned at the beginning. At the same time, however, certain technological requirements have to be met. For example, the advantages according to the teaching of (1) are to be retained, that is to say a so-called skip coating is to be avoided, that is to say a coating in which spots which are completely uncovered by coating compound can occur as a result of air bubbles. In addition, there should always be one at all times there is a constant gap in the area of the overflow ledge, and the gap width should be kept as small as possible according to the teaching of (1), so that there is in any case a very small or no overflow at this point.
Der Erfindung liegt somit die Aufgabe zugrunde, eine Streicheinrichtung gemäß dem Oberbegriff von Anspruch 1 derart zu gestalten, daß die gesamte Einrichtung so kompakt wie möglich wird, d.h. möglichst raumsparend gestaltet wird, daß ferner die technologischen Anforderungen an eine solche Düsenstreicheinrichtung weitgehend erfüllt werden, insbesondere bezüglich des Gleichmaßes des Strichauftrages, und daß schließlich die Streicheinrichtung möglichst einfach im Aufbau ist.The invention is therefore based on the object of designing a coating device in accordance with the preamble of claim 1 in such a way that the entire device is as compact as possible, i.e. is designed to be as space-saving as possible, furthermore that the technological requirements for such a nozzle coating device are largely met, in particular with regard to the uniformity of the coat application, and that the coating device is ultimately as simple as possible in construction.
Diese Aufgabe wird durch die kennzeichnenden Merkmale von Anspruch 1 gelöst.This object is solved by the characterizing features of claim 1.
Die darin enthaltenen einzelnen Elemente sind zwar für sich alleine bekannt. Jedoch wird die Streicheinrichtung durch deren geschickte Anordnung zu einer kompakten Baueinheit, die geringstmöglichen Raum beansprucht, aber dennoch die an sie gestellten Funktionen einwandfrei erfüllt.The individual elements contained therein are known on their own. However, the coating device is cleverly arranged into a compact unit that takes up as little space as possible, but nevertheless fulfills the functions placed on it perfectly.
Die Erfindung ist anhand der Zeichnung näher erläutert. Darin sind mehrere Ausführungsbeispiele einer düsenartigen Streicheinrichtung dargestellt, und zwar jeweils in einer Schnittebene, in der die Laufrichtung der Papierbahn liegt, und die zugleich senkrecht zur Papierbahn liegt. Funktionsgleiche Elemente sind mit denselben Bezugszeichen versehen. In allen Figuren umschlingt eine Papierbahn 1 eine in Pfeilrichtung umlaufende Gegenwalze 2.The invention is explained in more detail with reference to the drawing. Several exemplary embodiments of a nozzle-like coating device are shown therein, each in a sectional plane in which the running direction of the paper web lies and which is also perpendicular to the paper web. Functionally identical elements are provided with the same reference symbols. In all the figures, a paper web 1 wraps around a
Die in Fig. 1 dargestellte düsenartige Streicheinrichtung weist einen Düsenraum 3 auf. Dieser ist in Bahnlaufrichtung durch eine einlaufseitige Überlaufleiste 4 und eine Dosierleiste 5 begrenzt. Streichmasse wird einem Verteilrohr 6 zugeführt. Das Verteilrohr 6 hat eine Mehrzahl von hier nicht dargestellten Austrittsöffnungen, die mit einem Zufuhrkanal 7 in leitender Verbindung stehen, so daß Streichmasse durch den Kanal 7 zum Düsenraum 3 und damit an die Papierbahn 1 gelangt. Auf halbem Wege des Zufuhrkanales befinden sich Stolperschwellen 7.1, die eine Mikroturbulenz in der Streichmasse erzeugen. Ein Ableitkanal 8 stellt eine leitende Verbindung mit einer Überlaufrinne 9 her. Am Ende des Ableitkanales 8 befindet sich ein einstellbares Ventil 10 zum Steuern der Überlaufmenge. Eine Einrichtung 11 dient dem Regeln des Durchbiegungsausgleiches. Dabei kommt es insbesondere auf den Durchbiegungsausgleich der Dosierleiste 5 an. Es kann aber auch Einfluß auf die Durchbiegung der gesamten Streicheinrichtung genommen werden. Die Ausgleichseinrichtung 11 ist im vorliegenden Falle gemäß DE-A-39 25 517 gestaltet. Sie weist ein ortsfestes Joch 12 auf, eine Hülse 13, die das Joch 12 umgibt sowie Druckübertragungselemente 14, im vorliegenden Falle Luftbälge. Bei Beschicken der Luftbälge 14 mit Druckluft wird die Position der Hülse 13 und damit auch jene der Dosierleiste 5 verändert, so daß ein Durchbiegungsausgleich hergestellt wird. Gemäß der Erfindung kann die Ausgleichseinrichtung 11 derart gestaltet und angeordnet sein, daß ein genügend großer "innerer Hub" geschaffen wird, um auch die Weite des Spaltes zwischen der Kante der Dosierleiste 5 und der Papierbahn 1 einzustellen. Hierzu bedarf es somit keiner weiteren Einrichtung mehr. Im vorliegenden Falle ist eine Laser-Meßeinrichtung 15 vorgesehen, mit der sich die genaue Position der Kante der Dosierleiste 5 erfassen läßt. Ein hieraus gewonnenes Signal wird dazu verwendet, die Ausgleichseinrichtung 11 zu steuern.The nozzle-like coating device shown in FIG. 1 has a
Konstruktiv kann die gesamte Streicheinrichtung derart getrennt werden, daß die Ausgleichseinrichtung 11 allein aufdie Dosierleiste 5 einwirkt. Die Streicheinrichtung kann jedoch auch so gestaltet werden, daß die Ausgleichseinrichtung 11 auf die gesamte Streicheinrichtung einwirkt und wahlweise deren Durchbiegung korrigiert, oder deren Abstand zur Papierbahn 1.The entire coating device can be structurally separated in such a way that the
Wie man sieht, durchzieht Ableitkanal 8 die gesamte Streicheinrichtung im wesentlichen in diagonaler Richtung, ausgehend von der Kante der Dosierleiste 5 zur Überlaufrinne 9.As can be seen,
Die Überlaufrinne 9 dient gleichzeitig dazu, den sehr großen Überschuß aus Kanal 8 aufzufangen, wie auch den sehr kleinen Überlauf, der von der Überlaufleiste 4 herkommt. Wie man sieht, befindet sich zwischen Zufuhrkanal 7 und Ableitkanal 8 ein Strömungskörper 16. Dieser ist somit im wesentlichen begrenzt von Zufuhrkanal 7, Düsenraum 3 und Ableitkanal 8.The
Wie man weiterhin erkennt, ist die gesamte Streicheinrichtung als kompakte Baueinheit gestaltet, die im wesentlichen balkenförmig ist, und in der sämtliche funktionswichtigen Elemente zusammengefaßt sind. Im vorliegenden Falle sind die folgenden Elemente um einen imaginären Mittelpunkt herumkopiert: Verteilrohr 6, Strömungskörper 16, Laser-Meßeinrichtung 15, Ausgleichseinrichtung 11 und Überlaufrinne 9.As can also be seen, the entire coating device is designed as a compact structural unit, which is essentially bar-shaped, and in which all functionally important elements are combined. In the present case, the following elements are copied around an imaginary center point:
Ein weiterer Vorteil dieser Ausführungsform besteht darin, daß die Streichmasse an jeder Stelle eine eindeutige Strömungsrichtung hat, daß keine Stromkreuzungen auftreten, und daß sie - bis auf einen geringen Teilstrom an der Überlaufleiste 4 - bei Berührung mit der Papierbahn nur in deren Laufrichtung strömt. Damit ist eine wichtige Voraussetzung für einen sauberen, qualitativ hochwertigen Strich erfüllt, und zwar ungeachtet dessen, ob die Einrichtung als Vordosiereinrichtung oder als einzige Streicheinrichtung verwendet wird.Another advantage of this embodiment is that the coating slip has a clear flow direction at every point, that no current crossings occur, and that - except for a small partial flow on the overflow bar 4 - it only flows in the direction of travel when it comes into contact with the paper web. This fulfills an important prerequisite for a clean, high-quality line, regardless of whether the device is used as a pre-metering device or as the only coating device.
Auch die in Fig. 2 dargestellte Streicheinrichtung folgt denselben Prinzipien wie jene gemäß Fig. 1. Wie man sieht, sind die Elemente Verteilrohr 6, Strömungskörper 16 und Ausgleichseinrichtung 11 in Bahnlaufrichtung hintereinander angeordnet. Zulaufkanal 7 verbindet Verteilrohr 6 mit Düsenraum 3. Er nimmt hierbei einen im wesentlichen zur Papierbahn 1 senkrechten Verlauf. Ableitkanal 8 mit Ventil 10 mündet wiederum auf der Einlaufseite der Streicheinrichtung, d.h. dort, wo die Papierbahn 1 einläuft. Die Streichmasse steigt somit vom Verteilrohr im Zulaufkanal 7 nach oben, wird dabei durch Stolperschwellen 7.1 in eine gewisse, erwünschte Turbulenz versetzt, strömt sodann in ihre Hauptmenge an Ableitkanal 8 vorbei, wobei eine kleinere Teilmenge in den Ableitkanal gelangt, gelangt weiterhin zum Düsenraum 3, wo ein kleinerer Teil auf der Papierbahn verbleibt und durch den Spalt zwischen Papierbahn 1 und Überlaufleiste 5 austritt, während der größere Teil der Streichmasse als Überschuß den Strömungskörper 16 völlig umströmt und zum Ableitkanal 8 gelangt.The coating device shown in FIG. 2 also follows the same principles as that according to FIG. 1. As can be seen, the
Fig. 3 veranschaulicht eine weitere Ausführungsform, wobei allerdings eine gewisse Gegenströmung der Streichmasse gegenläufig zur Laufrichtung der Papierbahn 1 stattfindet.3 illustrates a further embodiment, although a certain counterflow of the coating slip takes place in the opposite direction to the running direction of the paper web 1.
