Description

Die Erfindung betrifft eine Vorrichtung zum Auftragen einer Schicht aus einer flüssigen, feinkeramischen Masse auf einen festen, kontinuierlich bewegten Träger.The invention relates to a device for applying a layer of a liquid, fine ceramic mass to a solid, continuously moving carrier.

Der Erfindung liegt die Aufgabe zugrunde, eine derartige Vorrichtung zu schaffen, die einfach aufgebaut und bedienbar ist und mit der eine flüssige, feinkeramische Masse so genau dosiert auf den Träger aufgetragen werden kann, daß sich eine Schicht gleichmäßiger Stärke bildet.The invention has for its object to provide such a device that is simple to set up and operate and with which a liquid, fine-ceramic mass can be applied to the carrier in such precise doses that a layer of uniform thickness is formed.

Erfindungsgemäß wird dies durch Anwendung der im Kennzeichen des Patentanspruchs 1 angegebenen Maßnahmen erreicht.According to the invention this is achieved by applying the measures specified in the characterizing part of patent claim 1.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Unteransprüchen und der Beschreibung eines Ausführungsbeispieles anhand der Zeichnung, die ein Ausführungsbeispiel in einer schematischen Seitenansicht zeigt.Further features and advantages of the invention result from the subclaims and the description of an exemplary embodiment with reference to the drawing, which shows an exemplary embodiment in a schematic side view.

Beim Ausführungsbeispiel ist auf einem Führungstisch 1 ein fester, zu beschichtender Träger 2 geradlinig geführt. Der Träger 2, der beispielsweise aus Stahlblech besteht, wird durch bekannte, nicht dargestellte Mittel kontinuierlich in Richtung des Pfeiles a bewegt. Oberhalb des Führungstisches 2 ist eine Walze 3 angeordnet, in deren Oberfläche 4 in gleichmäßigen Abständen Vertiefungen 5 in Form von achsparallelen Nuten eingeschnitten sind. Anstelle von achsparallelen Nuten als Vertiefungen können auch anders gestaltete Vertiefungen, die in gleichmäßiger Verteilung über den gesamten Umfang der Walze 3 angeordnet sind, Anwendung finden. Die Walze 3 besteht zweckmäßig aus Metall. Vor jedem Ende der Walze 3 ist je eine seitliche Wand 6 angeordnet. Zwischen den beiden Wänden 6 ist eine weitere Wand 7 vorgesehen, die fest an einer Quertraverse 8 angeschlossen ist. Die Wand 7 besteht aus einem elastisch verformbaren Werkstoff, beispielsweise Blech, und erstreckt sich von der Quertraverse 8 ausgehend in Richtung zur Walze 3. Das untere Ende der Wand 7 liegt dabei an der Walze 3 unmittelbar oberhalb des Trägers 2 an. Weiterhin sind mehrere Stellschrauben 9 vorgesehen, die je durch ein Gewinde in der Quertraverse 8 hindurchgeschraubt sind und deren vordere Enden auf den elastischen unteren Abschnitt der Wand 7 wirken.In the exemplary embodiment, a solid support 2 to be coated is guided in a straight line on a guide table 1. The carrier 2, which consists for example of sheet steel, is continuously moved in the direction of arrow a by known means, not shown. Above the guide table 2 there is a roller 3, in the surface 4 of which indentations 5 are cut at regular intervals in the form of axially parallel grooves. Instead of axially parallel grooves as depressions, differently shaped depressions, which are arranged in a uniform distribution over the entire circumference of the roller 3, can also be used. The roller 3 is suitably made of metal. A lateral wall 6 is arranged in front of each end of the roller 3. A further wall 7 is provided between the two walls 6 and is firmly connected to a crossbar 8. The wall 7 consists of an elastically deformable material, for example sheet metal, and extends from the crossmember 8 in the direction of the roller 3. The lower end of the wall 7 lies against the roller 3 directly above the carrier 2. Furthermore, a plurality of set screws 9 are provided, each of which is screwed through a thread in the crossmember 8 and whose front ends act on the elastic lower section of the wall 7.

Die Walze 3 bildet zusammen mit den beiden einander gegenüberliegenden Wänden 6, die abdichtend an der Walze anliegen, und der Wand 7 einen Vorratsraum für die aufzutragende keramische Masse 10. Diese Masse wird über ein oder mehrere Zuführrohre 11 in den Vorratsraum eingebracht, zweckmäßig in der Weise, daß die Oberfläche der flüssigen Masse 10 stets etwa in gleicher Höhe steht.The roller 3 forms together with the two mutually opposite walls 6, which bear sealingly against the roller, and the wall 7 a storage space for the ceramic mass 10 to be applied. This mass is introduced into the storage space via one or more feed pipes 11, expediently in the Way that the surface of the liquid mass 10 is always approximately the same height.

Zum Antrieb der Walze 3 ist ein Elektromotor, beispielsweise ein Gleichstromelektromotor 12 vorgesehen, auf dessen Achse eine Riemenscheibe 13 aufgesetzt ist. Die Riemenscheibe 13 steht über einen Riemen 14, beispielsweise einen Keilriemen, mit einer weiteren Riemenscheibe 15 auf der Achse der Walze 3 in Verbindung.To drive the roller 3, an electric motor, for example a direct current electric motor 12, is provided, on the axis of which a pulley 13 is placed. The pulley 13 is connected via a belt 14, for example a V-belt, to a further pulley 15 on the axis of the roller 3.

Weiterhin ist in Bewegungsrichtung des Trägers 2 hinter der Walze 3 eine Schichtdickenmeßeinrichtung 16 angeordnet, mit der die Dicke der auf den Träger aufgebrachten Schicht gemessen werden kann. Die Schichtdickenmeßeinrichtung 16 gibt die ermittelten Schichtdickenwerte an eine Steuereinrichtung 17, mit der die Drehzahl des Elektromotors 12 geändert werden kann. Die Steuereinrichtung kann jedoch auch auf ein stufenlos regelbares Getriebe wirken.Furthermore, in the direction of movement of the carrier 2, a layer thickness measuring device 16 is arranged behind the roller 3, with which the thickness of the layer applied to the carrier can be measured. The layer thickness measuring device 16 transmits the determined layer thickness values to a control device 17, with which the speed of the electric motor 12 can be changed. However, the control device can also act on a continuously variable transmission.

Im Betrieb der Vorrichtung nehmen die Vertiefungen 5 der in Richtung des Pfeiles b umlaufenden Walze 3 beim Durchlauf durch den Vorratsraum keramische Masse 10 auf. Da die Wand 7 an der Oberfläche 4 der Walze 3 anliegt, kann in einer bestimmten Zeiteinheit nur so viel Masse 10 aus dem Vorratsbehälter zum Träger 2 transportiert werden, wie dem Volumen der in dieser Zeit über den Träger hinweglaufenden Vertiefungen 5 entspricht, so daß sich auch bei sehr dünnflüssiger Masse eine sehr genaue Mengendosierung ergibt. Sobald eine Vertiefung 5 aus dem Bereich der Wand 2 austritt, fließt die hierin enthaltene Masse 10 auf den Träger 2. Hierdurch bilden sich zunächst quer zur Bewegungsrichtung a verlaufende Massestreifen. Infolge der Dünnflüssigkeit der Masse verteilen sich diese Streifen jedoch nach einer kurzen Zeit zu einer gleichmäßigen Schicht 18. Um in möglichst kurzer Zeit eine Schicht gleichmäßiger Dicke zu erreichen, ist es zweckmäßig, die Walze 3 mit einer Oberflächengeschwindigkeit anzutreiben, die über der Vorschubgeschwindigkeit des Trägers 2 liegt. Bei den so eng nebeneinander aufgebrachten Streifen sind die Lücken zwischen den Streifen kleiner und können sich daher schneller auffüllen.During operation of the device, the recesses 5 of the roller 3 rotating in the direction of arrow b absorb ceramic mass 10 as it passes through the storage space. Since the wall 7 abuts the surface 4 of the roller 3, only as much mass 10 can be transported from the storage container to the carrier 2 in a certain time unit as corresponds to the volume of the depressions 5 running over the carrier during this time, so that results in a very precise metering even with a very thin liquid. As soon as a depression 5 emerges from the region of the wall 2, the mass 10 contained therein flows onto the carrier 2. This initially forms mass strips which run transversely to the direction of movement a. As a result of the thin liquid of the mass, however, these strips distribute into a uniform layer 18 after a short time. In order to achieve a layer of uniform thickness in the shortest possible time, it is expedient to apply the roller 3 at a surface speed drive, which is above the feed speed of the carrier 2. With the strips placed so close together, the gaps between the strips are smaller and can therefore fill up faster.

Sollte, beispielsweise infolge Änderungen der Fließfähigkeit der Masse, die auf den Träger aufgebrachte Schicht 18 nicht die gewünschte Dicke haben, so wird dies von der Schichtdickenmeßeinrichtung ermittelt und über die Steuereinrichtung 17 ein Impuls auf den Motor 12 gegeben, der zu einer Änderung der Drehzahl des Motors und damit der Walze 3 führt. Wird die Geschwindigkeit der Walze erhöht, wobei selbstverständlich die Vorschubgeschwindigkeit des Trägers 2 konstant bleibt, so wird pro Zeiteinheit mehr Masse zugeführt, so daß die Dicke der Schicht 18 größer wird. Entsprechend wird durch Verminderung der Drehzahl der Walze 3 weniger Masse auf den Träger 2 aufgebracht. Diese Einrichtung schafft weiterhin die Möglichkeit, durch entsprechende Änderung der Grundeinstellung der Steuereinrichtung 17 unterschiedliche Schichtdicken voreinzustellen.If, for example as a result of changes in the flowability of the mass, the layer 18 applied to the carrier does not have the desired thickness, this is determined by the layer thickness measuring device and a pulse is given to the motor 12 via the control device 17, which leads to a change in the speed of the Motor and thus the roller 3 leads. If the speed of the roller is increased, the feed speed of the carrier 2 naturally remaining constant, more mass is supplied per unit of time, so that the thickness of the layer 18 becomes greater. Accordingly, by reducing the speed of the roller 3, less mass is applied to the carrier 2. This device also makes it possible to preset 17 different layer thicknesses by changing the basic setting of the control device accordingly.

Bei der vorstehend beschriebenen Arbeitsweise dienen die Stellschrauben 9 dazu, die Wand 7 in Anlage an der Oberfläche 4 der Walze 3 zu halten, insbesondere bei einem Abrieb eine Nachstellmöglichkeit zu bieten, wenngleich dies auch dadurch erreichbar ist, daß die Wand unter ihrer Eigenelastizität an der Oberfläche 4 der Walze 3 anliegt.In the above-described mode of operation, the set screws 9 serve to hold the wall 7 in contact with the surface 4 of the roller 3, in particular to offer an adjustment possibility in the event of abrasion, although this can also be achieved in that the wall has its own elasticity on the Surface 4 of the roller 3 abuts.

Sollte die Masse lO stark schmirgelnde Bestandteile enthalten, so ermöglichen es die Stellschrauben 9, einen geringen Spalt zwischen der Oberfläche 4 der Walze 3 und der Wand 7 einzustellen, wodurch der Abrieb an der Berührungsstelle der beiden Teile herabgesetzt werden kann. Die daraus resultierende größere Durchsatzmenge kann über eine Verminderung der Drehzahl der Walze 3 kompensiert werden.If the mass 10 contains heavily abrasive components, the set screws 9 allow a small gap between the surface 4 of the Adjust roller 3 and the wall 7, whereby the abrasion at the point of contact of the two parts can be reduced. The resulting larger throughput can be compensated for by reducing the speed of the roller 3.
