Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Einfärben einer Walze an einer Druckmaschine, enthaltend eine Kammerrakel zum Auftragen von Druckfarbe auf eine farbaufnehmende Walze, wobei die Kammerrakel eine sich in axialer Richtung zur farbaufnehmenden Walze erstreckende Farbkammer aufweist, die Farbkammer durch eine Schließrakel sowie durch eine in Bewegungsrichtung der farbaufnehmenden Walze nachfolgende Arbeitsrakel begrenzt ist und die der Farbkammer abgewandte Seite der Arbeitsrakel in Drehrichtung der farbaufnehmende Walze geneigt ist.The The invention relates to a device for coloring a roller on a printing press, containing a chambered doctor blade for applying printing ink to a ink-absorbing roller, wherein the chamber doctor blade in axial Having direction to the ink-receiving roller extending ink chamber, the paint chamber by a closing squeegee as well as by a in Direction of movement of the ink-absorbing roller subsequent work squeegee is limited and the ink chamber side facing away from the work squeegee is inclined in the direction of rotation of the ink-absorbing roller.
Es ist bekannt, Druckfarbe auf Walzen aufzubringen und anschließend mittels einer Rakel von der Walze abzustreifen. Ein weit verbreiteter Einsatzfall ist die Farbversorgung einer Rasterwalze durch eine Kammerrakel, wie es zum Beispiel bei Kurzfarbwerken üblich ist. Während des Betriebes kann sich auf einer der Walze abgewandten Seite der in Rotationsrichtung der Walze nachgeordneten Arbeitsrakel – insbesondere bei Druckfarben hoher Viskosität – Druckfarbe ansammeln. Diese störenden Farbansammlungen können unkontrolliert und zu zufälligen Zeiten auf die bereits abgerakelte Fläche der Walze gelangen und so unerwünschte Farbdichteschwankungen auf dem Bedruckstoff erzeugen.It It is known to apply printing ink on rollers and then by means of a squeegee from the roller strip. A widespread application is the ink supply of an anilox roller by a chambered doctor blade, such as it is common, for example, in short inking. During the Operation can be on a side facing away from the roller in Direction of rotation of the roller downstream working doctor blade - in particular for high viscosity inks - ink accumulate. These disturbing Color accumulations can uncontrolled and at random times on the already doctored area get the roller and so unwanted Create color density fluctuations on the substrate.

Einen
anderen Lösungsansatz
für dieses Problem
zeigt die
Durch die oben genannten Lösungen soll der Aufbau von Farbanhäufungen vermieden werden. Unvermeidlich jedoch ist, dass die Druckfarbe, wenn auch im begrenztem Umfang, über die Mantelfläche der Walze geführt wird. Durch die hohe Umfangsgeschwindigkeit der farbführenden Walzen in modernen Druckmaschinen werden dabei Farbpartikel infolge der Beugung um die Rakelspitze und Farbanhäufung an dieser von der Mantelfläche geschleudert. Es kommt zum Spritzen der Farbe, so dass die benachbarten Walzen und/oder der Bedruckstoff verschmutzt werden.By the above solutions intended to build up color accumulations be avoided. Inevitably, however, is that the printing ink, albeit to a limited extent, over the lateral surface of the Roller guided becomes. Due to the high peripheral speed of the ink-carrying Rolls in modern printing machines are thereby colored particles due to the Diffraction around the squeegee tip and color accumulation thrown at this from the lateral surface. It comes to spraying the paint, leaving the adjacent rollers and / or the printing material are soiled.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zum Einfärben einer Walze über eine Rakel zu entwickeln, durch die Farbanhäufungen nach der Rakel – in Rotationsrichtung der Walze gesehen – vermieden werden und die Druckfarbe zum Verhindern des Spritzens unverzüglich von der Mantelfläche der Walze entfernt werden.Of the Invention is therefore based on the object, a device for dye a roller over to develop a squeegee, by the color accumulations after the squeegee - in the direction of rotation seen the roller - avoided and the ink to prevent splashing immediately the lateral surface the roller are removed.
