Description
Die Erfindung betrifft ein Verfahren zum Einfärben einer Rasterwalze einer Rotationsdruckmaschine entsprechend dem Anspruch 1.The invention relates to a method for inking an anilox roller Rotary printing machine according to claim 1.
Durch die EP 06 63 293 A1 ist eine Vorrichtung zur
Einfärbung einer Rasterwalze bekannt, bei welcher in
einer vollgefüllten Farbkammer mit kreisförmigem
Querschnitt Druckfarbe um eine parallel zur Rasterwalze
verlaufende Längsachse rotiert.
Es sind eine negativ angestellte Arbeitsrakel und eine
positiv angestellte Schließrakel vorgesehen.EP 06 63 293 A1 discloses a device for inking an anilox roller, in which printing ink rotates in a fully filled ink chamber with a circular cross section about a longitudinal axis running parallel to the anilox roller.
A negative squeegee and a positive squeegee are provided.
Es ist eine vorgeformte Farbkammer erforderlich, in welche Druckfarbe hineingepumpt wird.A preformed ink chamber is required in which ink is pumped into it.
Die US 15 68 299 A beschreibt einen Farbkasten mit zwei zueinander in Umfangsrichtung einer Dosierwalze beabstandeten Farbmessern. Mittels eines einstellbaren Abstandes der Farbmesser zur Dosierwalze wird eine zu übertragende Farbschichtdicke festgelegt.US 15 68 299 A describes a paint box with two to each other in the circumferential direction of a metering roller spaced color knives. By means of an adjustable The distance between the ink knife and the metering roller becomes one transferring ink layer thickness set.
Die US 37 30 089 A zeigt einen Farbkasten, in dem sich während des Laufes eine Druckfarbenrolle ausbildet. Zum Dosieren der Druckfarbe ist ein Farbmesser zu einer Dosierwalze beabstandet. The US 37 30 089 A shows a paint box in which forms an ink roller during the run. To the Dosing the ink is one color meter at a time Metering roller spaced.
Der Erfindung liegt die Aufgabe zugrunde, ein Farbwerk zum Einfärben einer Rasterwalze in einer Rotationsdruckmaschine mit hochviskoser Druckfarbe zu schaffen.The invention has for its object an inking unit for coloring one To create anilox roller in a rotary printing machine with highly viscous printing ink.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruches 1 gelöst.This object is achieved by the features of claim 1 solved.
Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß wenig Druckfarbe in Umlauf ist, was bei einer Reinigung des Farbkastens und einem Druckfarbenwechsel von Vorteil ist. Infolge Fehlens einer besonders geformten Farbkammer bildet sich die rotierende Farbrolle oder Druckfarbenrolle ungestört und gleichmäßig aus, was ebenfalls zu einer gleichmäßigen und intensiven Einfärbung der Walze führt.The advantages that can be achieved with the invention exist especially in that there is little ink in circulation, what about cleaning the ink fountain and a Ink change is an advantage. As a result of absence A specially shaped ink chamber forms the rotating ink roller or ink roller undisturbed and even from what also to an even and intense The roller is colored.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die einzige Zeichnung zeigt einen Querschnitt durch eine schematische Darstellung eines auf einer Walze aufgesetzten Farbkastens mit zwei Rakeln.An embodiment of the invention is in the Drawing shown and will be described in more detail below described. The only drawing shows one Cross section through a schematic representation of a ink fountain with two mounted on a roller Squeegees.
Ein oben offener Farbkasten 1 hat eine linke und eine rechte Seitenwand 2; 3 sowie zwei der Peripherie 11 einer angetriebenen Walze 4 angepaßte abdichtende Stirnwände 6; 7. Der Farbkasten 1 erstreckt sich über die gesamte Länge der Walze 4, die als Rasterwalze ausgebildet ist, Unten an den Seitenwänden 2; 3 sind eine an die Walze 4 negativ angestellte Arbeitsrakel 8 sowie eine Schließrakel 9 auswechselbar angebracht.An ink fountain 1 open at the top has left and one right side wall 2; 3 and two of the periphery 11 a driven roller 4 adapted sealing End walls 6; 7. The ink fountain 1 extends over the entire length of the roller 4, the anilox roller is formed, at the bottom of the side walls 2; 3rd are a negative to the roller 4 Working squeegee 8 and a closing squeegee 9 interchangeable appropriate.
Im Farbkasten 1 befindet sich hochviskose Druckfarbe,
welche während des Maschinenlaufes eine sich in
horizontaler Richtung A bewegbare, im Uhrzeigersinn B
rotierende Farbrolle 12 ausbildet. Entsprechend der
Drehrichtung der Walze 4, z. B. im Gegenuhrzeigersinn C,
liegt die Farbrolle 12 sowohl auf einem Teil der
Oberfläche 11 der Walze 4 als auch auf einer
Arbeitsfläche 13 der Arbeitsrakel 8 sowie einer die
Farbrolle 12 in Produktionsrichtung C der Walze 4
begrenzenden Leitfläche 14 an.Ink box 1 contains highly viscous printing ink,
which one during the machine run

Die Leitfläche 14 wird z. B. von der Innenseite der
linken Seitenwand 2 gebildet und verläuft zur
Arbeitsfläche 13 der Arbeitsrakel 8 in einem stumpfen
Winkel Alpha, vorzugsweise von 110° bis 130°.The

sowie der Länge der Arbeitsrakel 8 gebildet.The working
Es ist auch möglich, die Walze 4 in
Uhrzeigerdrehrichtung laufen zu lassen, so daß die Rakel
9 zur Arbeitsrakel und die Rakel 8 zur Schließrakel wird
und die Farbrolle 12 an der Rakel 9 sowie an der
Innenfläche der rechten Seitenwand 3, einer Leitfläche
16 anliegt.It is also possible to roll 4 in
Let the clockwise rotation run so that the squeegee
9 becomes the working squeegee and the squeegee 8 becomes the closing squeegee
and the
Der Farbkasten 1 ist zwischen dem I. und II. oder im I.
oder im II. Quadranten eines durch die Rotationsachse 17
der Walze 4 verlaufenden rechtwinkligen
Koordinatensystems an der Peripherie 11 des Farbkastens
4 angeordnet.The ink fountain 1 is between the 1st and 2nd or 1st
or in the II. quadrant one through the axis of
Nach einer anderen Ausführungsvariante ist es möglich, je nach Drehrichtung der Walze 4, z. B. in Richtung C, nur eine Rakel, d. h. die negativ angestellte Arbeitsrakel 8 sowie zwei Stirnwände 6; 7 zu verwenden. Die Rakel 8 kann dabei je je nach Höhe des Betrages des Winkels alpha mit einer Seitenwand 2 zusammenwirken. According to another variant, it is possible to depending on the direction of rotation of the roller 4, z. B. towards C, only one squeegee, d. H. the negatively employed Squeegee 8 and two end walls 6; 7 to use. The doctor blade 8 can, depending on the amount of the Angle alpha cooperate with a side wall 2.
Liegt der Winkel Alpha im Bereich von 180°, so befindet
sich die Arbeitsfläche 13 sowie die Leitfläche 14 in
derselben Ebene und können somit auch eindeutig
ausgeführt werden.If the angle alpha is in the range of 180 °, it is located
