Abstract

The invention relates to a coating device, which in addition to a rotary screen (2) comprises a central feed bore (3) for feeding coating material into the interior of the rotary screen and a squeegee (4). The device is also provided with an insert (7) inside the rotary screen of the coating device, said insert reducing the free volume inside the rotary screen (2) by at least 50 %. This permits an advantageous reduction of the quantity of required surplus material, thus producing a significant cost-saving, in particular for small coating surfaces or small numbers of substrates to be coated.

Description

Beschreibung description
Beschichtungsvorrichtungcoater
Die Erfindung betrifft eine Beschichtungsvorrichtung, insbesondere für die Beschichtung eines Substrates mit Katalysatormaterial .The invention relates to a coating device, in particular for coating a substrate with catalyst material.
Stand der TechnikState of the art
Für die Beschichtung von Bauteilen oder Membranen mit Katalysatormaterial sind zahlreiche Verfahren und Vorrichtungen aus der Literatur bekannt . Dazu zählen das Sprühverfahren, das Rakelverfahren, oder auch der Sieb- druck.Numerous methods and devices are known from the literature for coating components or membranes with catalyst material. These include the spraying process, the doctor blade process or screen printing.
Beim letztgenannten wird die Beschichtungsmasse, insbesondere ein Katalysatormaterial, mit Hilfe eines Abstreifers durch ein feinmaschiges Sieb auf das Bauteil, bzw. die Membran gedrückt. Als Druckform dienen Siebgewebe aus Metall-, Textil- oder Kunststoff den. Der Vorteil beim Siebdruck liegt in der hohen Schichtstärke, die aufgebracht werden kann. Man unterscheidet bei Siebdruck zwischen dem Flachsiebdruck und dem Rotati- onssiebdruck.In the latter case, the coating composition, in particular a catalyst material, is pressed onto the component or the membrane through a fine-meshed sieve with the aid of a scraper. Screen fabrics made of metal, textile or plastic serve as the printing form. The advantage of screen printing is the high layer thickness that can be applied. In screen printing, a distinction is made between flat screen printing and rotary screen printing.
Beim Flachsiebdruck wird die Druckform durch einen mit einem Gewebe bespannten Rahmen gebildet . Das Bauteil wird unter den Rahmen gebracht, bedruckt und weiter transportiert.In flat screen printing, the printing form is formed by a frame covered with a fabric. The component is placed under the frame, printed and transported on.
Beim Rotationssiebdruck wird häufig ein Edelstahlgewebe eingesetzt, welches zu einem Hohlzylinder geformt wird. Im Innenraum des Zylinders sind Zuführungen für die Beschichtungsmasse und die Rakel (Abstreifer) angeordnet. Aufgrund des rotativen Aufbaus ist ein kontinuierlicher Druckprozeß möglich.Stainless steel mesh is often used for rotary screen printing, which is formed into a hollow cylinder. In the interior of the cylinder, feeds for the coating compound and the doctor blade (wiper) are arranged. Due to the rotary structure, a continuous printing process is possible.
In einem zylindrischen Rotationssieb wird das Beschich- tungsmaterial typischerweise durch eine Zuführung über eine seitliche Bohrung oder einen zentralen Zuführungskanal zentral zugeführt. Durch die Rotation des Siebes während des Betriebs sammelt sich das Beschichtungsma- terial vor dem Abstreifer. Um eine lückenhafte Beschichtung durch die Siebporen auf das Substrat ausschließen zu können, muß immer ein Überschuß an Be- schichtungsmaterial vor dem Abstreifer vorhanden sein. Typischerweise rollt sich das Beschichtungsmaterial an dem Abstreifer hoch und fällt vor dem Abstreifer wieder auf das Sieb zurück. Das bedeutet, dass ein Teil des Beschichtungsmaterials immer als ein vorsorglich überschüssiger Anteil während des Verfahrens eingesetzt werden muß, der nicht zur eigentlichen Beschichtung zur Verfügung steht. Dieser Anteil ist um so ungünstiger, je dünner die aufzutragende Schicht und/oder je kleiner die zu beschichtende Fläche pro Substrat oder Bauteil und Verfahrensschritt ist.In a cylindrical rotary screen, the coating material is typically fed centrally through a feed via a lateral bore or a central feed channel. As the screen rotates during operation, the coating material collects in front of the scraper. In order to be able to rule out a patchy coating through the screen pores on the substrate, there must always be an excess of coating material in front of the stripper. Typically, the coating material rolls up on the stripper and falls back onto the screen in front of the stripper. This means that part of the coating material must always be used as a precautionary excess during the process, which is not available for the actual coating. This proportion is all the more unfavorable the thinner the layer to be applied and / or the smaller the area to be coated per substrate or component and process step.
Dies bedeutet insgesamt, dass die Menge an Beschichtungsmaterial in dem Rotationssieb regelmäßig größer ist, als die aufzutragende Menge. Als Folge wird dadurch mehr Beschichtungsmaterial eingesetzt, als für die eigentliche Beschichtung notwendig wäre. Dies führt insbesondere bei teuren Beschichtungsmaterialien zu einem nachteilig hohen Kostenaufwand des Verfahrens. Aufgabe und LösungOverall, this means that the amount of coating material in the rotary screen is regularly larger than the amount to be applied. As a result, more coating material is used than would be necessary for the actual coating. This leads to a disadvantageously high cost of the method, in particular in the case of expensive coating materials. Task and solution
Aufgabe der Erfindung ist es, eine Beschichtungsvorrichtung zu schaffen, bei der selbst kleinste Mengen an Beschichtungsmaterial effektiv aufgetragen werden und damit Kosten eingespart werden können.The object of the invention is to provide a coating device in which even the smallest amounts of coating material are effectively applied and thus costs can be saved.
Die Aufgabe wird gelöst durch eine Vorrichtung mit den Merkmalen des Hauptanspruchs . Vorteilhafte Ausführungsformen der Erfindung sind den darauf rückbezogenen Un- teransprüchen zu entnehmen.The object is achieved by a device with the features of the main claim. Advantageous embodiments of the invention can be found in the subclaims which refer back to it.
Gegenstand der ErfindungSubject of the invention
Die erfindungsgemäße Beschichtungsvorrichtung weist einThe coating device according to the invention has
Rotationssieb, eine zentrale Zuführungsbohrung zur Zu- führung von Beschichtungsmaterial ins Innere des Rotationssiebes, sowie einen Abstreifer auf. Weiterhin umfaßt die Beschichtungsvorrichtung einen Einsatz innerhalb des Rotationssiebes, welches das freie Volumen innerhalb des Rotationssiebes um wenigstens 50 % ver- ringert . Vorteilhaft wird das Leervolumen sogar um mehr als 80 % verringert. Durch die Reduktion des Leervolumens innerhalb des Rotationssiebes wird dasjenige Volumen an Beschichtungsmaterial verringert, welches die vollständige Beschichtung vor dem Abstreifer sicher- stellt (vorsorglich, überflüssiges Volumen) . DieserRotary screen, a central feed hole for feeding coating material into the interior of the rotary screen, and a scraper. Furthermore, the coating device comprises an insert within the rotary screen, which reduces the free volume within the rotary screen by at least 50%. The empty volume is advantageously even reduced by more than 80%. By reducing the empty volume within the rotary screen, the volume of coating material that ensures the complete coating in front of the scraper is reduced (precautionary, unnecessary volume). This
Effekt ist um so größer, je geringer das verbleibende Leervolumen ausfällt. Insbesondere ist das Leervolumen vor dem Abstreifer (bezogen auf den Betrieb des Rotationssiebes) zu verringern.The smaller the remaining empty volume, the greater the effect. In particular, the empty volume in front of the scraper (based on the operation of the rotary screen) must be reduced.
Dazu eignet sich einerseits ein ebenfalls zylindrischer Einsatz, der zentral innerhalb des Rotationssiebes an- geordnet ist. Die Zuführung des Beschichtungsmaterials erfolgt über eine Zuführungsbohrung, bzw. einen zentralen Zuführungskanal, an die sich ein weiterer Kanal anschließt. Durch diesen weiteren Kanal wird das Be- schichtungsmaterial direkt an das Sieb herangeführt . Vorteilhaft ist der weitere Kanal derart angebracht, dass er das Beschichtungsmaterial dem Sieb in der Nähe des Abstreifers zuführt. Auf diese Weise gelangt das Beschichtungsmaterial während des Betriebs der Be- Schichtungsvorrichtung direkt vor dem Abstreifer an das Sieb. Damit reduziert sich das Leervolumen, welches von dem vorsorglich eingebrachten Beschichtungsmaterial eingenommen wird, vorteilhaft nur noch auf den weiteren Kanal und den Bereich direkt vor dem Abstreifer.On the one hand, a likewise cylindrical insert is suitable for this, which is positioned centrally within the rotary screen. is ordered. The coating material is supplied via a feed bore or a central feed channel, which is followed by a further channel. The coating material is fed directly to the screen through this additional channel. The further channel is advantageously attached in such a way that it feeds the coating material to the sieve in the vicinity of the scraper. In this way, the coating material reaches the screen directly in front of the stripper during operation of the coating device. The empty volume which is taken up by the coating material introduced as a precaution is thus advantageously only reduced to the further channel and the area directly in front of the scraper.
In einer vorteilhaften Ausführungsform der Beschichtungsvorrichtung ist diese mit einer zusätzlichen Um- mantelung des Rotationssiebes ausgestattet . Das eingesetzte Beschichtungsmaterial enthält regelmäßig Lö- sungsmittel, die eine Verarbeitung des Beschichtungsmaterials erst ermöglichen. Während des Betriebes der Beschichtung tritt eine Verdunstung des Lösungsmittels ein, die eine weitere Verarbeitung zunächst erschwert und dann verhindert .In an advantageous embodiment of the coating device, it is equipped with an additional sheathing of the rotary screen. The coating material used regularly contains solvents that only make it possible to process the coating material. During the operation of the coating, evaporation of the solvent occurs, which initially makes further processing difficult and then prevents it.
Die erfindungsgemäße Ummantelung des Rotationssiebes verringert das freie Volumen außerhalb der Beschichtungsvorrichtung derart, daß die Verdunstung des Lösungsmittels verringert und damit die Verarbeitungszeit des Beschichtungsmaterials, im Vergleich zum Stand der Technik, deutlich verlängert werden kann. Spezieller BeschreibungsteilThe casing of the rotary screen according to the invention reduces the free volume outside the coating device in such a way that the evaporation of the solvent is reduced and the processing time of the coating material can thus be significantly extended compared to the prior art. Special description part
Nachfolgend wird der Gegenstand der Erfindung anhand von Figuren näher erläutert, ohne daß der Gegenstand der Erfindung dadurch beschränkt wird. Es zeigen Figur 1 : Querschnitt durch eine Rotationssiebtrommel gemäß dem Stand der Technik Figur 2 : Querschnitt durch eine erfindungsgemäße AusführungsformThe subject matter of the invention is explained in more detail below with reference to figures, without the subject matter of the invention being restricted thereby. FIG. 1 shows a cross section through a rotary screen drum according to the prior art. FIG. 2 shows a cross section through an embodiment according to the invention

Die Figur 1 zeigt eine Rotationssiebtrommel, wie sie im Stand der Technik zu finden ist, im Querschnitt. Das äußere rotierende Sieb (2) wird über die zu beschichtende Folie, Schicht (1) etc. geführt. Die mitlaufende Gegenwalze (5) verhindert das Durchbiegen der Folie während der Beschichtung. Das Material zur Beschichtung wird durch eine zentrale Öffnung (3) , bzw. einen Kanal in die Rotationssiebtrommel eingeführt. Ein gewisser Überschuß an Material sammelt sich während der Beschichtung im Inneren des Siebes vor dem Rakel (4) , und gewährleistet, eine gleichbleibende und vollständige Beschichtung. Nachteilig muß dieser Überschuß auch bei kleinen Beschichtungsflachen erfolgen.FIG. 1 shows a rotary sieve drum, as can be found in the prior art, in cross section. The outer rotating sieve (2) is passed over the film, layer (1) etc. to be coated. The counter roller (5) prevents the film from bending during coating. The material for coating is introduced through a central opening (3) or a channel into the rotary screen drum. A certain excess of material collects during the coating inside the screen in front of the doctor blade (4), and ensures a constant and complete coating. This excess must also be disadvantageous small coating areas.
In der Figur 2 ist eine Ausführungsform der Erfindung dargestellt. Zusätzlich zu den Komponenten, die schon aus dem Stand der Technik bekannt sind, umfaßt die Siebtrommel einen zylindrischen Einsatz (7) , der im Inneren der Siebtrommel, zentriert angebracht ist. Die Zuführung (3a) des Beschichtungsmaterials erfolgt über einen zentralen Kanal (3) durch den Einsatz hindurch bis zur Peripherie des Siebes. Der Kanal kann dabei sowohl als rohrförmiger Kanal als auch als Spalt über die gesamte Breite der Siebtrommel ausgestaltet sein. Vorteilhaft verbleibt nur ein geringes Volumen zwischen dem Einsatz (7) , dem Sieb (2) und dem Rakel (4) , so dass schon ein geringer Überschuss an Beschichtungsmaterial zu einer vollständigen und gleichmäßigen Beschichtung führen. Die Zuführung des Beschichtungsmaterials kann daher sehr dosiert erfolgen und für einen Beschichtungsvorgang insgesamt minimiert werden. FIG. 2 shows an embodiment of the invention. In addition to the components which are already known from the prior art, the screening drum comprises a cylindrical insert (7) which is mounted in the center of the inside of the screening drum. The coating material is fed (3a) via a central channel (3) through the insert to the periphery of the screen. The channel can be configured both as a tubular channel and as a gap over the entire width of the screening drum. Advantageously, only a small volume remains between the insert (7), the screen (2) and the doctor blade (4), so that even a small excess of coating material leads to a complete and uniform coating. The supply of the coating material can therefore take place in a very metered manner and can be minimized overall for a coating process.
