Abstract

A printing method using at least one transfer roller, whose roller surface is charged with a coating material, for example a toner. The coating material is directly or indirectly transferred from the transfer roller to a support surface of a transfer element, before being transferred at least partially from the transfer element to a workpiece to be coated. According to this invention, the transfer element has a stretching element which forms the support surface and the support surface is stretched in the direction of the surface by a stretching device. This ensures that this method can also be used to easily coat 3-dimensional surfaces which are curved in space.

Es ist Aufgabe der Erfindung, eine Beschichtungsvorrichtung, bzw. ein Beschichtungsverfahren zu schaffen, mit dem insbesondere auch drei-dimensional im Raum gewöbite Flächen auf einfache Weise beschichtet werden können.It is an object of the invention to provide a coating device or a To create coating processes with which in particular also three-dimensional surfaces that are curved in the room can be coated in a simple manner.

Diese Aufgabe wird durch eine Druckvorrichtung gemäß Anspruch 1 und ein Druckverfahren gemäß Anspruch 8 gelöst.This task will solved by a printing device according to claim 1 and a printing method according to claim 8.

Das Dehnelement kann mittels der Dehnvorrichtung derart verformt werden, dass es sich an die Kontur der zu bedruckenden Fläche anpaßt. Auf diese Weise lassen sich auch komplexe Verläufe von dreidimensional ausgeformten Fächen auf einfache Weise bedrucken. The expansion element can be deformed by means of the expansion device in such a way that it adapts to the contour of the surface to be printed. Leave this way complex courses from three-dimensionally shaped areas to simple ones Print wise.

Beispielsweise eignet sich das Druckverfahren bzw. die Druckvorrichtung zum Bedrucken von, aus der Ebene heraus verformten Glas-, Glaskeramik-, Keramikoder Kunststoff-Werkstücken. Insbesondere 3D-verformte Teile aus oben genannten Werkstoffen lassen sich derzeit nicht ohne Weiteres mit den bisher üblichen Siebdrucktechniken kostengünstig bedrucken. Mit dem Druckverfahren bzw. der Druckvorrichtung lassen sich 3D-verformte Glasscheiben, z. B. gewölbte Backofenfrontscheiben, Glas-Bedienpanel, Möbelglastüren oder gewölbtes Architekturglas, 3D-verformte Glaskeramik-Kochflächen mit beispielweise tieferliegenden Kochbereichen oder aus der Ebene heraus verformte, höher liegende Bedienbereiche, sowie gewölbte Glaskeramik-Kaminsichtscheiben, 3D-verformte Keramikteile, beispielsweise Geschirrteile, wie Teller und Schüsseln und 3D-verformte Kunststoffoberflächen bedrucken.For example, the printing method or the printing device is suitable for Printing of glass, glass ceramic, ceramic or deformed out of the plane Plastic workpieces. In particular 3D deformed parts from above The materials mentioned cannot currently be easily used with the previous ones Print conventional screen printing techniques inexpensively.

Gemäß einer bevorzugten Ausgestaltungsvariante der Erfindung ist es vorgesehen, dass das Übertragungselement als endlos umlaufendes Band ausgebildet ist, das entlang seiner Längserstreckung zumindest bereichsweise mit Dehnelementen bestückt ist oder das selbst als Dehnelement ausgebildet ist.According to a preferred embodiment variant of the invention, it is provided that that the transmission element is designed as an endlessly circulating band is that along its longitudinal extent at least in regions Expansion elements is equipped or that is itself designed as an expansion element.

Das Endlosband ermöglicht eine fortlaufende, wirtschaftliche Beschichtung von Werkstücken. Hierbei kann es insbesondere vorgesehen sein, dass das Übertragungselement als Gummiband ausgebildet ist.The endless belt enables a continuous, economical coating of Workpieces. It can in particular be provided that the transmission element is designed as a rubber band.

Die Druckvorrichtung kann beispielsweise dergestalt sein, dass die Dehnvorrichtung einen Stempel aufweist, dass der Stempel eine Stempelfläche aufweist, die an die zu bedruckende Druckfläche des Werkstückes angepaßt ausgebildet ist, und dass die Trägerfläche des Dehnelementes aus ihrer gestreckten Ausgangslage mittels des Stempels auf die Druckfläche aufpressbar ist. Hierbei dehnt der Stempel das Dehnelement. Es ist jedoch auch denkbar, dass die Trägerfläche des Dehnelementes unter Zuhilfenahme von Druckluft oder unter Vakuumeinfluss auf das Werkstück aufgedrückt wird.The printing device can, for example, be such that the stretching device has a stamp, that the stamp has a stamp surface, which is adapted to the printing surface of the workpiece to be printed, and that the support surface of the expansion element from its extended starting position can be pressed onto the printing surface by means of the stamp. Here, the Stamp the expansion element. However, it is also conceivable that the carrier surface of the Expansion element with the aid of compressed air or under the influence of vacuum the workpiece is pressed on.

Um eine Beschädigung von empfindlichen Werkstücken, insbesondere von sprödbrüchigen Glas-, Glaskeramik- oder Keramik-Werkstücken während des Druckvorgangs zu verhindern, kann es vorgesehen sein, dass die Stempelfläche des Stempels von einem elastischen, nachgiebigen Material gebildet ist.In order to damage sensitive workpieces, in particular brittle fragile glass, glass ceramic or ceramic workpieces during the To prevent printing, it can be provided that the stamp surface the stamp is formed from an elastic, resilient material.

Damit zwischen zwei Druckvorgängen kein Beschichtungsmaterial verschleppt wird, ist es vorgesehen, dass dem Übertragungselement eine Reinigungsvorrichtung zugeordnet ist, mittels der die Trägerfläche des Dehnelementes nach Beendigung des Druckvorgangs reinigbar ist.So that no coating material is carried over between two printing processes is provided that the transmission element is a cleaning device is assigned by means of which the support surface of the expansion element Completion of the printing process is cleanable.

Denkbar ist es auch, dass die Trägerfläche des Dehnelementes mit einer Silikonbeschichtung versehen ist oder von einem Silikongummi gebildet ist. Eine solche Oberflächengestaltung verhindert, dass nach dem Druckvorgang Beschichtungsmaterial an der Trägerfläche haften bleibt.It is also conceivable that the support surface of the expansion element with a Silicone coating is provided or is formed by a silicone rubber. A Such surface design prevents coating material after the printing process sticks to the support surface.

Wenn der Druckvorrichtung fortlaufend, beispielsweise von einem Förderband, Werkstücke zugeführt werden, dann kann das Druckverfahren derart konzipiert sein, dass das als Endlosband umlaufende Übertragungselement an der Dehnvorrichtung vorbeigeführt wird, und dass das Endlosband während der Dehnung der Trägerfläche und der Durchführung des Druckvorganges angehalten wird. Gleichzeitig mit der Taktung des Endlosbandes muß auch das Förderband angehalten werden.If the printing device continues, for example from a conveyor belt, Workpieces are fed, then the printing process can be designed in this way be that the transmission element rotating as an endless belt on the stretching device is passed, and that the endless belt while stretching the support surface and the execution of the printing process is stopped. At the same time as the endless belt is clocked, the conveyor belt must also be stopped.

Ein kontinuierlicher Fertigungsprozeß läßt sich dann erreichen, wenn vorgesehen ist, dass das als Endlosband umlaufende Übertragungselement an der Dehnvorichtung vorbeiführbar ist, dass während der Dehnung der Trägerfläche und der Durchführung des Druckvorganges die Dehnvorrichtung und gleichzeitig das Werkstück mit dem Endlosband mitgeführt werden.A continuous manufacturing process can be achieved if provided is that the circulating transmission element on the stretching device can be passed that during the expansion of the support surface and Execution of the printing process, the stretching device and at the same time Workpiece with the endless belt.

Die Erfindung ist außerdem dadurch gekennzeichnet, dass der Dehnvorrichtung eine Korona zugeordnet ist, die die Übertragung des Beschichtungsmaterials auf die zu bedruckende Druckfläche des Werkstückes bewirkt oder unterstützt.The invention is also characterized in that that the stretching device is associated with a corona that the Transfer of the coating material to the printing surface of the Workpiece causes or supports.

Während des Betriebes der Druckvorrichtung wird die Übertragungswalze 24 mit den Tonerteilchen 27 beschichtet. Gegebenfalls werden auch die Übertragungswalzen 28 mit farbigen Tonerteilchen beschichtet. Die Übertragungswalzen 24 und 28 drehen sich im Uhrzeigersinn. Die Transportwalzen 21 hingegen drehen sich gegen den Uhrzeigersinn. Dementsprechend wird der auflaufende Trum 22.2 von rechts nach links an den Übertragungswalzen 24 und 28 vorbeigeführt. Die Umlaufgeschwindigkeit des Gummibandes 22 und der Oberfläche der Übertragungswalzen 24 und 28 ist aufeinander abgestimmt. Zur Übertragung der Farbpartikel 27 werden Koronen 35 verwendet. Diese übertragen die Farbpartikel 27 auf den auflaufenden Trum 22.2 des Gummibandes 22. Die Farbpartikel 27 werden auf dem Gummiband 22 an der linken Transportwalze 21 vorbeitransportiert und gelangen dann in den Bereich des ablaufenden Trummes 22.1. Wenn die Farbpartikel 27, die beispielsweise ein Motiv gestalten, unterhalb der Dehnvorrichtung 30 angelangt sind, wird die Transportwalze 21 gestoppt. Dann kann der Stempel 33 in Richtung auf die Werkstücke 11 mittels des Antriebes 31 verfahren werden. Dabei dehnt sich das Gummiband 22 und legt sich an die Stempelfläche 34 an. Der Stempel 33 drückt dann das Gummiband 22 auf die Druckfläche 12 auf. Vorteilhafterweise kann der Stempel 33 gleichzeitig auch mit einer Heizvorrichtung versehen sein, die eine Fixierung der Farbpartikel 27 auf der Werkstückoberfläche erreicht.During the operation of the printing device, the transfer roller 24 is with coated the toner particles 27. If necessary, the transfer rollers 28 coated with colored toner particles. The transfer rollers 24 and 28 rotate clockwise. The transport rollers 21, however rotate counterclockwise. Accordingly, the accumulating Run 22.2 from right to left past the transfer rollers 24 and 28. The rotational speed of the rubber band 22 and the surface of the Transfer rollers 24 and 28 are coordinated. To transfer the Color particles 27, corones 35 are used. These transfer the color particles 27 on the run-up strand 22.2 of the rubber band 22. The color particles 27 are transported past the left transport roller 21 on the rubber band 22 and then get into the area of the running run 22.1. If the Color particles 27, for example, design a motif below the Stretching device 30 have arrived, the transport roller 21 is stopped. Then can the punch 33 in the direction of the workpieces 11 by means of the drive 31st be moved. The rubber band 22 expands and lies against the Stamp area 34. The stamp 33 then presses the rubber band 22 on the Printing area 12 on. Advantageously, the stamp 33 can also be used at the same time be provided with a heating device which fixes the color particles 27 on the Workpiece surface reached.

Nach Beendigung der Übertragung der Farbpartikel 27 wird der Stempel 33 wieder in seine obere Ausgangsstellung zurückgefahren. Das Gummiband 22 kann dann weiter gedreht werden, wozu die Transportwalze 21 gedreht wird.After the transfer of the color particles 27 has ended, the stamp 33 becomes again retracted to its upper starting position. The rubber band 22 can then can be rotated further, for which purpose the transport roller 21 is rotated.

Gleichzeitig fährt auch die Transportvorrichtung 10 und stellt das nächste Werkstück 11 unter die Dehnvorrichtung 30. Das mit dem Druck 13 versehene Werkstück 11 wird aus dem Wirkungsbereich der Druckvorrichtung heraustransportiert.At the same time, the transport device 10 also moves and sets the next one Workpiece 11 under the stretching device 30. The one provided with the pressure 13 Workpiece 11 is transported out of the effective range of the printing device.

Um zu verhindern, dass Tonerteilchen 27, die nicht auf das Werkstück 11 übertragen wurden und dementsprechend noch an dem Gummiband 22 anhaften, verschleppt werden, wird die Reinigungsvorrichtung 23 eingesetzt. Die Reinigungsvorrichtung 23 kann beispielweise eine beheizte Walze sein, die auf dem Gummiband 22 abrollt. Der beheizten Walze ist ihrerseits wieder eine Bürste zugeordnet, die die Tonerteilchen 27 abnimmt. Um ein Verschlepen von Tonerteilchen 27 sicher zu verhindern, kann das Gummiband 22 auch an seiner Trägerfläche mit einer Silikonbeschichtung versehen sein. Denkbar ist es auch, eine Schicht auf Silikongummi auf das Gummiband 22 aufzubringen.To prevent toner particles 27 that are not on the workpiece 11 have been transferred and accordingly still adhere to the rubber band 22, are carried away, the cleaning device 23 is used. The Cleaning device 23 can be, for example, a heated roller that is on the rubber band 22 rolls. The heated roller is in turn a brush assigned, which decreases the toner particles 27. A carryover of toner particles To safely prevent 27, the rubber band 22 can also on his Carrier surface with a silicone coating. It is also conceivable apply a layer of silicone rubber to the rubber band 22.
