Description

Die vorliegende Erfindung betrifft eine Vorrichtung zur Applizierung eines flüssigen und/oder pastösen Beschichtungsstoffs auf Oberflächen von Werkstücken, gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a device for Application of a liquid and / or pasty coating material on surfaces of workpieces, according to the Preamble of claim 1.

Eine Vorrichtung der eingangs genannten Art, die eine Auftragswalze mit einer glatten Außenumfangsfläche, z.B. aus Gummi, zur Applizierung des Beschichtungsstoffs auf die Oberflächen von Werkstücken verwendet, ist aus der DE 83 06 769 U1 bekannt. Vorteilhaft ist bei dieser bekannten Vorrichtung, daß sie in der Lage ist, auch großflächige Werkstücke schnell und gleichmäßig zu beschichten, wobei nur sehr geringe Beschichtungsstoffverluste auftreten. Ein schwerwiegender Nachteil dieser bekannten Vorrichtung liegt aber darin, daß mit ihr wegen der glatten Außenumfangsfläche der Auftragswalze lediglich ebene Oberflächenbereiche beschichtet werden können. Aus diesem Grund kommt es bei profilierten und/oder strukturierten Werkstückoberflächen zu einer unvollständigen Beschichtung, wenn diese mittels einer Auftragswalze bearbeitet werden. In der Praxis werden deshalb Vorrichtungen, die mit einer Auftragswalze arbeiten, nur für die Beschichtung von glattflächigen ebenen Werkstücken eingesetzt. A device of the type mentioned, the one Applicator roll having a smooth outer peripheral surface, e.g. rubber, for application of the coating material The surfaces used by workpieces is out of the DE 83 06 769 U1 known. It is advantageous in this known Device that it is capable, even large-scale To coat workpieces quickly and evenly, whereby only very small coating material losses occur. A serious disadvantage of these known But device is that with her because of the smooth Outer peripheral surface of the applicator roll only level Surface areas can be coated. For this Reason is profiled and / or structured Workpiece surfaces to an incomplete coating, if this works by means of an applicator roll become. In practice, therefore, devices, who work with an applicator roll, just for the Coating of smooth flat workpieces used.

Bei Werkstücken, die eine profilierte und/oder strukturierte Oberfläche aufweisen, müssen andere Beschichtungsverfahren eingesetzt werden, wobei hier in erster Linie Aufspritzen und Aufgießen der Beschichtungsstoffe zu nennen sind. Beim Aufspritzen der Beschichtungsstoffe tritt allerdings der Nachteil auf, daß nur spritzfähige, d.h. relativ dünnflüssige Beschichtungsstoffe eingesetzt werden können und daß außerdem ein relativ großer Teil des verspritzten Beschichtungsstoffs nicht auf das Werkstück gelangt und somit verlorengeht. Beim Aufgießen von Beschichtungsstoffen tritt das Problem auf, eine gleichmäßige Schichtdicke zu erzeugen, was gerade bei profilierten und/oder strukturierten Werkstückoberflächen besonders schwierig wird.For workpieces that have a profiled and / or textured Surface must have other coating methods be used, and here in the first place To call spraying and pouring the coating materials are. When spraying the coating materials occurs however, the disadvantage is that only sprayable, i. relatively low-viscosity coating materials are used and that besides, a relatively large part of the sprayed coating material not on the workpiece gets lost and thus lost. When pouring coating materials the problem occurs, a uniform Layer thickness to produce what just profiled at and / or structured workpiece surfaces especially becomes difficult.

Schließlich ist aus der DE 43 27 421 A1 eine Vorrichtung für die Beschichtung von Werkstücken bekannt, die mit einer Auftragsbürste arbeitet. Die Auftragsbürste ist eine drehantreibbare zylindrische Bürste, die auf ihrem Umfang mit Borsten besetzt ist und die quer zu dem durch die Vorrichtung hindurchlaufenden Werkstück angeordnet ist. Dabei ist die Länge der Auftragsbürste in dieser Richtung mindestens so groß wie die Breite des breitesten zu beschichtenden Werkstücks. Über eine Beschichtungsstoff-Aufgabeeinrichtung wird über die jeweils benötigte oder über die gesamte Länge der Auftragsbürste der Beschichtungsstoff auf deren Borsten aufgegeben. Unter Drehung der Auftragsbürste und gleichzeitigem Durchlauf des Werkstücks durch die Vorrichtung wird dann der Beschichtungsstoff von der Auftragsbürste, genauer von deren Borsten, auf das Werkstück übertragen und dort verstrichen. Alternativ kann bei derartigen Vorrichtungen der Beschichtungsstoff auch vor der Auftragsbürste unmittelbar auf die zu beschichtende Oberfläche aufgegeben, z.B. aufgegossen, werden und anschließend durch die Auftragsbürste bei Vorschub des Werkstücks verteilt und verstrichen werden. Mit einer solchen Vorrichtung lassen sich zwar auch Werkstücke mit profilierter und/oder strukturierter Oberfläche in einem Arbeitsgang beschichten, jedoch wird dabei in den ebenen Oberflächenbereichen des Werkstücks nicht die Beschichtungsqualität wie bei einer Vorrichtung mit einer glatten Auftragswalze erreicht. Nachteilig ist zudem eine Vorrichtung mit Auftragsbürste technisch relativ aufwendig, weil insbesondere die Zuführung und gleichmäßige Aufgabe des Beschichtungsstoffs auf die Auftragsbürste oder die Werkstück-Oberfläche schwierig ist. In der Praxis erfordert eine solche Vorrichtung eine Vielzahl von Pumpen, Leitungen, Ventilen, Düsen und/oder Walzen für die Zuführung, Aufgabe und Verteilung des Beschichtungsstoffs, was zwangsläufig aufgrund der vielen Einzelteile zu einer teuren Konstruktion mit einer erhöhten Stör- und Schadensanfälligkeit führt. Deshalb ist eine intensive Überwachung und Wartung der Vorrichtung erforderlich, um einen zuverlässigen Einsatz mit vertretbar geringem Ausschuß bei den fertig beschichteten Werkstücken zu gewährleisten.Finally, from DE 43 27 421 A1 a device known for the coating of workpieces with an order brush works. The order brush is a rotary drivable cylindrical brush on her Circumference is occupied with bristles and which transversely to the through arranged the device passing workpiece is. The length of the order brush is in this Direction at least as large as the width of the widest to be coated workpiece. About a coating material feeding device will be about the one needed each or over the entire length of the application brush the coating material is applied to the bristles. Under Rotation of the application brush and simultaneous run of the workpiece through the device is then the Coating material from the application brush, more precisely from whose bristles, transferred to the workpiece and there passed. Alternatively, in such devices the coating material also immediately before the application brush abandoned on the surface to be coated, e.g. infused, and then by the order brush distributed at the feed of the workpiece and elapsed become. Leave with such a device Although also workpieces with profiled and / or coated structured surface in one operation, however, it does so in the flat surface areas the workpiece does not like the coating quality in a device with a smooth applicator roll reached. Another disadvantage is a device with application brush technically relatively expensive, because in particular the feeding and even application of the coating material on the application brush or the workpiece surface difficult. In practice, one requires such device a plurality of pumps, lines, Valves, nozzles and / or rollers for the supply, task and distribution of the coating material, which inevitably due to the many items to an expensive construction with an increased susceptibility to malfunction and damage leads. That is why intensive monitoring and Maintenance of the device required to be a reliable Use with justifiable little committee in the to ensure finished coated workpieces.

Für die vorliegende Erfindung stellt sich deshalb die Aufgabe, eine Vorrichtung der eingangs genannten Art zu schaffen, die die oben dargelegten Nachteile vermeidet und mit der insbesondere in einem einzigen Arbeitsgang eine schnelle, gleichmäßige und qualitativ hochwertige Beschichtung von Werkstücken möglich ist, die neben ebenen auch profilierte und/oder strukturierte Oberflächenbereiche aufweisen, wobei gleichzeitig die Vorrichtung einfach aufgebaut und zuverlässig betreibbar sein soll.Therefore, for the present invention, the Task, a device of the type mentioned above which avoids the disadvantages set out above and in particular in a single operation a fast, steady and high quality Coating of workpieces is possible, in addition to level also profiled and / or structured surface areas have at the same time the device designed to be simple and reliable.

Die Lösung dieser Aufgabe gelingt durch eine Vorrichtung der eingangs genannten Art mit den kennzeichnenden Merkmalen des Patentanspruchs 1.The solution to this problem is achieved by a device of the type mentioned above with the characterizing features of claim 1

Mit der erfindungsgemäßen Vorrichtung wird vorteilhaft erreicht, daß in einem Durchlauf Werkstücke mit einem Beschichtungsstoff versehen werden können, die neben ebenen auch profilierte und/oder strukturierte Oberflächenbereiche, die gegen die ebenen Bereiche zurückspringen, aufweisen. Dabei wird der in der Regel den größten Teil der Werkstückoberfläche bildende ebene Oberflächenbereich von der Auftragswalze, also einer Walze mit einer glatten Außenumfangsfläche, mit dem Beschichtungsstoff versehen, was hier eine hohe Oberflächengüte der Beschichtung sicherstellt. Die Oberflächenbereiche, die von der Auftragswalze nicht beschichtbar sind, weil sie beim Vorbeilauf des Werkstücks an der Auftragswalze Abstand von dieser aufweisen, werden im selben Durchlauf von einem oder mehreren zusätzlichen Applikationselementen beschichtet. Dabei nutzen die zusätzlichen Applikationselemente jeweils die Auftragswalze als Einrichtung zur Zuführung des Beschichtungsstoffs. Die Auftragswalze wird, wie üblich, über ihre gesamte Länge mit dem Beschichtungsstoff versehen. Beim Durchlauf des Werkstücks durch die Vorrichtung verbleibt zwangsläufig auf den Umfangsbereichen der Auftragswalze, die nicht mit dem Werkstück in Kontakt kommen, der Beschichtungsstoff in voller Dicke und ist somit in Arbeitsrichtung gesehen hinter dem Kontaktbereich zwischen Auftragswalze und Werkstück noch vorhanden. Diesen verbliebenen Beschichtungsstoff nehmen die Applikationselemente von der Auftragswalze ab und bringen ihn auf die zuvor von der Auftragswalze nicht beschichteten Oberflächenbereiche des Werkstücks. Da die Profilierung und/oder Strukturierung von Werkstücken sehr unterschiedlich sein kann, sind die Applikationselemente in ihrer Positionierung relativ zum Werkstück und auch relativ zur Auftragswalze verstellbar und in einer geeigneten Position feststellbar. Auf diese Weise wird gewährleistet, daß sowohl eine gute Abnahme des Beschichtungsstoffs durch die Applikationselemente von der Auftragswalze als auch eine gute, d.h. insbesondere gleichmäßige Abgabe des Beschichtungsstoff mit einer gewünschten Beschichtungsdicke von den Applikationselementen auf die noch zu beschichtenden Bereiche der Oberfläche des Werkstücks erfolgt. Die zusätzlichen Applikationselemente benötigen vorteilhaft keine eigene Einrichtungen zur Zuführung, Verteilung und Aufgabe von Beschichtungsstoff, was die Vorrichtung insgesamt einfach hält und kostengünstig herstellbar und betreibbar macht. Außerdem besteht die vorteilhafte und wirtschaftliche Möglichkeit, vorhandene Vorrichtungen, die nur mit Auftragswalzen arbeiten, nachträglich mit einem oder mehreren zusätzlichen Applikationselementen der oben beschriebenen Art auszustatten. Hierdurch ist eine Nachrüstung auch von vorhandenen Vorrichtungen mit relativ geringem Aufwand möglich, wodurch das Einsatzspektrum dieser Vorrichtungen wesentlich erweitert werden kann. Bei besonderen, in der Praxis zwar selten aber doch auftretenden Anwendungsfällen, in denen die Werkstück-Oberfläche nicht vollflächig, sondern nur in streifenförmigen Bereichen mit Beschichtungsstoff versehen werden soll, kann die erfindungsgemäße Vorrichtung auch mit von der Werkstück-Oberfläche abgehobener Auftragswalze betrieben werden. In dieser besonderen Betriebsart dient die Auftragswalze lediglich der Zuführung des Beschichtungsstoffs zu den Applikationselementen, die nun allein den Beschichtungsstoff auf die Werkstück-Oberfläche auftragen.With the device according to the invention is advantageous achieved that in a single pass workpieces with a Coating material can be provided next to even profiled and / or structured surface areas, that jump back against the plane areas, exhibit. This is usually the largest Part of the workpiece surface forming flat surface area from the applicator roll, so a roller with a smooth outer circumferential surface, with the coating material provided, which here a high surface quality of Ensures coating. The surface areas that from the applicator roll are not coatable because they when passing the workpiece on the applicator roll distance from this will be in the same run of one or more additional application elements coated. The additional application elements make use of this in each case the applicator roll as an institution for supplying the coating material. The applicator roll is, as usual, over its entire length with the coating material Mistake. During the passage of the workpiece through the device inevitably remains on the peripheral areas the applicator roller, not with the workpiece come in contact, the coating material in full Thickness and is thus seen behind in working direction the contact area between applicator roll and workpiece still there. This remaining coating material take the application elements from the applicator roll from and bring him to the previously from the applicator roll uncoated surface areas of the workpiece. As the profiling and / or structuring of Workpieces can be very different, are the Application elements in their positioning relative to Workpiece and also adjustable relative to the applicator roll and in a suitable position detectable. To this Way, it ensures that both a good decrease of the coating material through the application elements from the applicator roll as well as a good, i. especially uniform delivery of the coating material with a desired coating thickness of the application elements on the areas of the still to be coated Surface of the workpiece is done. The additional application elements advantageously do not need their own Facilities for the supply, distribution and abandonment of Coating material, making the device overall easy holds and cost-effectively manufactured and operable power. In addition, there is the advantageous and economical Possibility to use existing devices with only Application rollers work, with one or later several additional application elements of the above To equip type. This is a retrofit also of existing devices with relatively low Effort possible, whereby the range of application of this Devices can be significantly expanded. at special, although rare in practice but occurring Use cases in which the workpiece surface not over the entire surface, but only in strip-shaped Areas should be provided with coating material, can the device according to the invention also with from the Workpiece surface of lifted applicator roller operated become. In this special mode, the applicator roll is used only the supply of the coating material to the application elements, which now alone the Apply coating material to the workpiece surface.

Bevorzugt ist vorgesehen, daß am Umfang des Applikationselements als Mittel zur Abnahme und Abgabe des Beschichtungsstoffs ein Borstenbesatz und/oder eine Schwamm- oder Filzauflage vorgesehen ist. Die konkrete Auswahl der Mittel zur Abnahme und Abgabe des Beschichtungsstoffs richtet sich nach dem jeweiligen Einsatzfall und insbesondere nach den Eigenschaften des Beschichtungsstoffs und der zu beschichtenden Oberfläche. Da die Applikationselemente innerhalb der Vorrichtung leicht zugänglich sind, können diese auch bei Bedarf komplett ausgetauscht werden. Wenn die Applikationselemente mit auswechselbaren Auflagen oder Besätzen versehen sind, genügt es, letztere auszuwechseln.It is preferably provided that on the circumference of the application element as a means for the removal and release of the coating material a bristle trim and / or a sponge or felt pad is provided. The concrete selection the means for the removal and delivery of the coating material depends on the particular application and in particular according to the properties of the coating material and the surface to be coated. As the application elements within easy reach of the device are, they can also be completely replaced when needed become. If the application elements with interchangeable Pads or trimmings are provided is sufficient to change the latter.

Um die Vorrichtung möglichst flexibel einsetzen und an verschiedene zu beschichtende Werkstücke anpassen zu können, ist vorgesehen, daß die Vorrichtung mehrere nebeneinander angeordnete, einzeln einstellbare Applikationselemente umfaßt. Auf diese Weise können auch Werkstücke mit relativ komplizierter Oberflächenprofilierung oder -strukturierung bearbeitet werden. Auch besteht die Möglichkeit, mehrere schmale Werkstücke, z.B. Leisten oder Profilbretter, parallel durch die Vorrichtung zu führen und zu beschichten, wobei für jedes einzelne der parallel laufenden Werkstücke ein oder mehrere Applikationselemente eingesetzt werden können. Bedarfsweise können auch jeweils nicht benötigte Applikationselemente in eine Ruheposition verfahren werden, in der sie weder mit der Auftragswalze noch mit der Oberfläche des Werkstücks in Kontakt treten.To use the device as flexible as possible and on to adapt different workpieces to be coated, it is envisaged that the device several side by side arranged, individually adjustable application elements includes. In this way, also workpieces with relatively complicated surface profiling or structuring be edited. There is also the possibility several narrow workpieces, e.g. Last or last Profiled boards to pass parallel through the device and to coat, taking for each one of the parallel running workpieces one or more application elements can be used. If necessary, you can also not required application elements in one Rest position in which they are neither with the applicator roll still with the surface of the workpiece contact.

In einer konkreten Ausgestaltung der Vorrichtung wird vorgeschlagen, daß die Applikationselemente an einer gemeinsamen Quertraverse gehaltert sind und daß die Quertraverse insgesamt in einer ersten Richtung in ihrem Abstand relativ zum Werkstück und in einer zweiten Richtung in ihrem Abstand relativ zur Auftragswalze verfahrbar und festlegbar ist. Die Verwendung einer Quertraverse ermöglicht einerseits eine stabile Konstruktion und eine einfache Nachrüstung von vorhandenen, mit einer Auftragswalze arbeitenden Vorrichtungen, und bietet andererseits die Möglichkeit, Grundeinstellungen, die für alle Applikationselemente gemeinsam vorzunehmen sind, einfach und zeitsparend durchzuführen.In a concrete embodiment of the device is proposed that the application elements to a common Cross-beam are supported and that the cross-beam overall in a first direction in their distance relative to the workpiece and in a second direction movable in their distance relative to the applicator roll and is definable. The use of a crossbeam on the one hand allows a stable construction and a simple retrofit of existing, with an applicator roll working devices, and on the other hand offers the possibility of basic settings for all Application elements are common, simple and save time.

Zur Gewährleistung der gewünschten Anpassungsfähigkeit der Vorrichtung an unterschiedliche Werkstücke ist zusätzlich vorzugsweise jedes Applikationselement relativ zur Quertraverse in wenigstens zwei, vorzugsweise in drei Raumkoordinatenrichtungen verstellbar und festlegbar. In einer einfachen Ausführung der Vorrichtung kann die Verstellung und Festlegung der Applikationselemente ganz oder teilweise manuell erfolgen. Darüberhinaus besteht auch die Möglichkeit, für die Verstellung und Festlegung der Applikationselemente Servoeinrichtungen zu nutzen, wie sie aus dem Bereich von Werkzeugmaschinen bekannt sind. Dann besteht auch die Möglichkeit, zur Steuerung der einzelnen Applikationselemente und der Vorrichtung insgesamt eine elektronische Steuereinheit einzusetzen, wie sie beispielsweise von CNC-gesteuerten Werkzeugmaschinen im Prinzip bekannt ist.To ensure the desired adaptability the device to different workpieces is additional preferably each application element relative to the crossbeam in at least two, preferably in three spatial coordinate directions adjustable and definable. In a simple embodiment of the device can the adjustment and definition of the application elements completely or partially done manually.

In the following, embodiments of the device according to the invention will be described. The figures of the drawing show:
FIG. 1
a device in a first embodiment in longitudinal section in a schematic representation,
FIG. 2
the device of Figure 1 in plan view and
FIG. 3
the apparatus in an amended embodiment in an end view, wherein an applicator roll shown in Figure 1 and 2 in Figure 3 is omitted for clarity.

Wie die Figuren 1 und 2 der Zeichnung zeigen, besitzt das hier dargestellte Ausführungsbeispiel einer Vorrichtung 1 zur Applizierung eines flüssigen und/oder pastösen Beschichtungsstoffs auf Oberflächen von Werkstücken 3 drei wesentliche Komponenten, nämlich eine Auftragswalze 2, mehrere zusätzliche Applikationselemente 4 und eine Werkstück-Transporteinrichtung 5. As shown in Figures 1 and 2 of the drawing has the embodiment of a device shown here 1 for the application of a liquid and / or pasty Coating material on surfaces of workpieces 3 three essential components, namely an applicator roll 2, several additional application elements 4 and a workpiece transport 5.

Die Transporteinrichtung 5, die in den Figuren 1 und 2 rein schematisch dargestellt ist, ist von bekannter Bauart und deshalb hier nicht näher zu beschreiben. Mittels dieser Transporteinrichtung 5 können Werkstücke 3, hier z.B. Leisten oder Profilbretter, mit einer in Richtung der Pfeile 30 weisenden Arbeitsrichtung unter der Auftragswalze 2 hindurchgeführt und unterstützt werden. Die Auftragswalze 2 ist quer zur Arbeitsrichtung 30 um eine Drehachse 20 drehbar gelagert. In ihrem zur Einlaufseite der Vorrichtung 1 weisenden Bereich ist parallel zur Auftragswalze 2 in einem geringen, einstellbaren Abstand von dieser eine Dosierwalze 24 angeordnet. Sie dient zur Verteilung des über wenigstens eine Rohrleitung 22 von oben her zuführbaren Beschichtungsstoffs 23 über die gesamte Länge der Auftragswalze 2. Die Dosierwalze 24 erzeugt je nach ihrem Abstand von der Auftragswalze 2 eine vorgebbare Schichtdicke des Beschichtungsstoffs 23 auf dem Umfang der Auftragswalze 2 und bestimmt somit die Stärke des Beschichtungsstoffs 23 auf dem Werkstück 3.The transport device 5, which in the figures 1 and 2 is shown purely schematically, is of known design and therefore not to be described here. through this transport device 5 can workpieces 3, here e.g. Moldings or profile boards, with one in direction the arrows 30 facing working direction under the applicator roll 2 are passed and supported. The Application roller 2 is transverse to the direction of work 30 by one Rotary shaft 20 rotatably mounted. In her to the inlet side the device 1 facing area is parallel to Application roller 2 in a small, adjustable distance arranged by this one metering roller 24. It serves for Distribution of at least one pipe 22 of top coatable coating material 23 over the entire Length of applicator roller 2. The metering roller 24 generates depending on their distance from the applicator roll 2 a predefinable layer thickness of the coating material 23 the scope of the applicator roll 2 and thus determines the Thickness of the coating material 23 on the workpiece 3.

Wie oben erwähnt ist, handelt es sich bei den hier zu beschichtenden Werkstücken 3 um Leisten oder Profilbretter, die hier an ihren Längskanten je einen dünneren, profilierten Randabschnitt aufweisen. Die nach oben weisenden Oberflächenbereiche 33 der Randabschnitte springen gegenüber dem ebenen Haupt-Oberflächenbereich 32 des Werkstücks 3 nach unten zurück, so daß die Rand-Oberflächenbereiche 33 von der Auftragswalze 2 nicht mit Beschichtungsstoff 23 beschichtet werden können.As mentioned above, these are the ones here coating workpieces 3 around strips or profile boards, here at their long edges a thinner, have profiled edge portion.

Auf die ebenen Haupt-Oberflächenbereiche 32 gelangt der Beschichtungsstoff 23 durch Drehung der Auftragswalze 2 im Sinne des Drehpfeils 21 und eine gleichzeitige Linearbewegung der Werkstücke 3 in Arbeitsrichtung 30. Dabei berührt der Umfang der Auftragswalze 2 in seinem unteren Bereich die ebenen Oberflächenbereiche 32 der Werkstücke 3 oder läuft zumindest in einem so geringen Abstand über diese, daß der Beschichtungsstoff 23 auf diese zu beschichtenden ebenen Oberflächenbereiche 32 der Werkstücke 3 übertragen wird.On the flat main surface areas 32 of the arrives Coating material 23 by rotation of the application roller. 2 in the sense of the rotary arrow 21 and a simultaneous linear movement the workpieces 3 in the direction of 30th Dabei touches the circumference of the applicator roll 2 in its lower Area the flat surface areas 32 of the workpieces 3 or overflows at least at such a small distance this, that the coating material 23 to be coated on this planar surface areas 32 of the workpieces 3 is transmitted.

Um dennoch auch die tiefer liegenden Rand-Oberflächenbereiche 33 der Werkstücke 3 in demselben Durchlauf durch die Vorrichtung 1 mit Beschichtungsstoff 23 versehen zu können, ist in Arbeitsrichtung 30 gesehen hinter der Auftragswalze 2 die Anordnung mehrerer Applikationselemente 4 vorgesehen. Bei dem in den Figuren 1 und 2 der Zeichnung dargestellten Ausführungsbeispiel der Vorrichtung 1 bestehen die Applikationselemente 4 jeweils aus einer Scheibe, die auf ihrem Umfang mit einem pinselartigen Borstenbesatz 42 versehen ist. Die Applikationselemente 4 sitzen hier auf einer gemeinsamen Welle 14 und sind um eine Drehachse 40, die hier parallel zur Drehachse 20 der Auftragswalze 2 verläuft, im Sinne des Drehpfeils 41 wahlweise in der einen oder der anderen Drehrichtung drehantreibbar. Hierzu ist z.B. ein in Figur 1 und 2 nicht dargestellter Antriebsmotor vorgesehen. Die Welle 14 und die Applikationselemente 4 sind über geeignete, hier nicht dargestellte Träger gehalten und in ihrer Position relativ zur Auftragswalze 2 und relativ zum Werkstück 3 verstellbar und festlegbar. Die Positionierung der Applikationselemente 4 erfolgt so, daß sie im Betrieb der Vorrichtung 1 von der Auftragswalze 2 den dort verbliebenen Beschichtungsstoff 23 abnehmen, und zwar in den Umfangsbereichen der Auftragswalze 2, die über die tiefer liegenden Oberflächenbereiche 33 des Werkstücks laufen. Der mittels der Applikationselemente 4, hier mittels des daran angebrachten Borstenbesatzes 42 von der Auftragswalze 2 abgenommene Beschichtungsstoff 23 wird durch die Drehung der Applikationselemente 4 nach unten transportiert und auf die zuvor noch nicht durch die Auftragswalze 2 beschichtete, nach unten versetzten Rand-Oberflächenbereiche 33 der Werkstücke 3 übertragen und durch den Borstenbesatz 42 verstrichen und vergleichmäßigt. Dabei werden gleichzeitig auch die in der Figur 1 parallel zur Zeichnungsebene liegenden Kanten zwischen dem Haupt-Oberflächenbereich 32 und den Rand-Oberflächenbereichen 33 der Werkstücke 3 mit Beschichtungsstoff beschichtet. Eigene Mittel zur Zuführung, Abgabe und Verteilung von Beschichtungsstoff auf die einzelnen Applikationselemente 4 benötigt die Vorrichtung 1 vorteilhaft nicht, weil dafür die ohnehin vorhandene Auftragswalze 2 benutzt wird.Nevertheless, also the lower-lying edge surface areas 33 of the workpieces 3 in the same run through the device 1 is provided with coating material 23 can, seen in the direction of work 30 behind the applicator roll 2 the arrangement of several application elements 4 provided.
