Abstract
Description
Die Erfindung betrifft eine Druckmaschine mit einem eine Rakeleinrichtung enthaltenden Farbwerk, bei dem eine Rasterwalze der Rakeleinrichtung zugeordnet istThe The invention relates to a printing press with a squeegee device containing inking, in which associated with an anilox roller of the doctor device is
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.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.

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 Rasterwalze über eine Rakeleinrichtung zu entwickeln, durch die Farbanhäufungen an der Rakel und auf der Rakelwalze nach der Rakel (in Rotationsrichtung der Walze gesehen) vermieden werden und die Druckfarbe zum Verhindern des Spritzens unverzüglich von der Mantelfläche der Rasterwalze entfernt wird.Of the Invention is therefore based on the object, a device for dye an anilox roller over to develop a squeegee device, by the color accumulations on the doctor blade and on the doctor roller after the doctor blade (in the direction of rotation the roller seen) are avoided and the ink to prevent spraying immediately from the lateral surface the anilox roller is removed.
Erfindungsgemäß wird die Aufgabe durch eine Vorrichtung mit den Merkmalen des 1. Anspruchs gelöst.According to the invention Task by a device having the features of the first claim solved.
