Description
Die Erfindung betrifft eine Kammerrakel eines mit einer Rasterwalze versehenen Farbwerkes einer Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a chambered doctor blade of an inking unit of a rotary printing press provided with an anilox roller according to the preamble of
Aus der EP 04 38 731 A2 ist eine Kammerrakel bekannt. Eine Farbkammer der Kammerrakel wird stirnseitig mittels Seitenbacken abgedichtet. Diese Seitenbacken sind jeweils mit einem an eine Rasterwalze anstellbaren Dichtungsmittel versehen, das einer Krümmung einer Mantelfläche der Rasterwalze angepaßt ist. Diese Dichtungsmittel sind aus elastischem Material und an ihrer Berührfläche zur Mantelfläche der Rasterwalze mit einem reibungsarmen Werkstoff beschichtet.A chambered doctor blade is known from EP 04 38 731 A2. An ink chamber of the chamber doctor blade is sealed on the front side by means of side jaws. These side jaws are each provided with a sealant which can be adjusted to an anilox roller and which is adapted to a curvature of a lateral surface of the anilox roller. These sealants are made of elastic material and are coated with a low-friction material on their contact surface with the outer surface of the anilox roller.
Nachteilig ist hierbei, daß Beschichtungsmaßnahmen notwendig sind, um eine reibungsarme Kontaktfläche der Dichtungsmittel zur Rasterwalze zu erhalten.The disadvantage here is that coating measures are necessary in order to obtain a low-friction contact surface of the sealing means with the anilox roller.
Die US 51 50 651 A zeigt eine gattungsgemäße Kammerrakel, deren Farbkammer mittels Seitenbacken abgedichtet wird. Diese Seitenbacken sind mit als Schmiertaschen wirkenden Vertiefungen versehen.US 51 50 651 A shows a generic doctor blade, the ink chamber of which is sealed by means of side jaws. These side jaws are provided with depressions which act as lubrication pockets.
Der Erfindung liegt die Aufgabe zugrunde, eine Kammerrakel eines mit einer Rasterwalze versehenen Farbwerkes einer Rotationsdruckmaschine zu schaffen, wobei stirnseitige Seitenbacken der Kammerrakel mit einer Dichtungsfläche gegen eine Mantelfläche einer Rasterwalze gedrückt werden und bei drehender Rasterwalze Festkörperreibung zwischen Seitenbacken und Rasterwalze vermieden wird.The invention has for its object to provide a chamber doctor blade of an inking unit provided with an anilox roller of a rotary printing press, wherein the side side jaws of the chamber doctor blade are pressed with a sealing surface against a lateral surface of an anilox roller and while rotating Anilox roller Solid friction between side jaws and anilox roller is avoided.
Diese Aufgabe wird erfindungsgemäß durch eine Kammerrakel mit den Merkmalen des kennzeichnenden Teiles des Anspruches 1 gelöst.This object is achieved by a chambered doctor blade with the features of the characterizing part of
In vorteilhafter Weise wird durch die erfindungsgemäße Kammerrakel Reibung minimiert, wodurch nur noch geringe Wärmeentwicklung entsteht. Hiermit wird ein Verschleiß von Seitenbacken als auch einer Mantelfläche einer Rasterwalze minimiert, wodurch eine höhere Standzeit erfolgt und Maschinenstillstandszeiten vermieden werden.
In besonders vorteilhafter Weise wird durch die geringe Wärmeentwicklung eine Gasblasenbildung im Bereich der Seitenbacken verhindert, was zu einer verbesserten Farbführung der Rasterwalze führt und somit die Druckqualität steigert.
Im Vergleich zum Stand der Technik sind keine aufwendigen Gleitbeläge notwendig.
Durch den selbsttätig entstehenden minimalen Spalt tritt nur eine minimale Farbmenge aus der Kammerrakel aus, wodurch Wulstbildung und somit Spritzen der Rasterwalze weitgehend vermieden wird.Friction is advantageously minimized by the chambered doctor blade according to the invention, as a result of which only little heat is generated. This minimizes wear on the side jaws as well as on the outer surface of an anilox roller, which results in a longer service life and machine downtimes are avoided.
In a particularly advantageous manner, the low heat development prevents gas bubbles from forming in the area of the side jaws, which leads to improved ink guidance of the anilox roller and thus increases the print quality.
Compared to the prior art, no elaborate sliding linings are necessary.
Due to the automatically generated minimal gap, only a minimal amount of ink emerges from the chamber doctor blade, which largely prevents the formation of beads and thus splashing of the anilox roller.
Die erfindungsgemäße Kammerrakel ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The chambered doctor blade according to the invention is shown in the drawing and is described in more detail below.

Eine Kammerrakel 1 wirkt mit einer Rasterwalze 2 eines Kurzfarbwerkes zusammen. Die Kammerrakel 1 erstreckt sich axial parallel zur Rasterwalze 2. Über einer Länge der Rasterwalze 2 können mehrere, nebeneinander angeordnete Kammerrakel 1, beispielsweise zwei sich jeweils über halbe Rasterwalzenlänge erstreckende Kammerrakel 1 vorgesehen sein. Es können aber auch beispielsweise druckplattenbreite Kammerrakel 1 vorgesehen sein, um auf der Rasterwalze 2 mehrere Farben zu verwenden oder die Farbzufuhr zonenweise abzustellen. Die Kammerrakel 1 besteht im wesentlichen aus einem Grundkörper 3, einem Arbeitsrakelblatt 4, einem Schließrakelblatt 6 und einem rechten bzw. linken Seitenbacken 7, 8. Der Grundkörper 3 ist mit einer Vertiefung 11 versehen und dessen walzennahe Enden 11, 12 weisen bezüglich einer radialen Richtung der Rasterwalze 2 geneigte Befestigungsflächen 13, 14 auf. Zwischen diesen Befestigungsflächen 13, 14 und Befestigungsleisten 16, 17 werden das Arbeitsrakelblatt 4 bzw. das Schließrakelblatt 6 beispielsweise mittels Schrauben eingespannt. Der Grundkörper 3 kann wie im dargestellten Beispiel einstückig oder aber auch mehrteilig, z. B. in axialer Richtung zweigeteilt, ausgebildet sein. An axial begrenzenden Stirnflächen 18, 19 des Grundkörpers 3 sind die Seitenbacken 7, 8 angeordnet, wobei diese jeweils an ihrer der Rasterwalze 2 zugewandten Dichtfläche 21 eine Krümmung der Rasterwalze 2 aufweisen.
Die Seitenbacken 7, 8, Arbeits-, Schließrakelblatt 4, 6 und die Vertiefung 9 des Grundkörpers 3 begrenzen somit eine Farbkammer 22 des Kammerrakels 1.
Im Bereich dieser Farbkammer 22 ist eine innere Stirnfläche 23, 24 des jeweiligen Seitenbackens 7, 8 mit einer in Richtung Farbkammer 22 weisenden Öffnung 26 versehen, und die Dichtfläche 21 der Seitenbacken 7, 8 weist eine als Schmier- und Dichttasche wirkende Vertiefung 27 auf. Die Öffnung 26 und die Vertiefung 27 sind miteinander verbunden.
In einem ersten Ausführungsbeispiel (Fig. 1 und Fig. 2) ist ein Einschnitt 28, 29 durch die Dichtfläche 21 vorgesehen, der gleichzeitig als Vertiefung 27 und Öffnung 26 dient. Dieser Einschnitt 28, 29 ist U-förmig ausgebildet, mit einer Breite b28, z. B. 0,25 mm, und einer Tiefe t28, z. B. 14 mm, und erstreckt sich über die gesamte Breite b7 der Seitenbacken 7, 8. Zudem kann der Einschnitt 28, 29 mit der der Farbkammer 22 zugewandten Stirnfläche 23, 24 des Seitenbackens 7, 8 einen in Drehrichtung weisenden Öffnungswinkel Alpha, z. B. 45°, einschließen.A
The
In the area of this
In a first exemplary embodiment (FIGS. 1 and 2), an
Bei einem zweiten Ausführungsbeispiel (Fig. 3 und Fig. 4) ist die Vertiefung 27 als kegelförmige Bohrung 31 ausgebildet, die zentrisch bezüglich der Breite der Dichtfläche 21 liegt und deren maximaler Durchmesser d31, z. B. kleiner als die Breite b7 der Seitenbacken 7, 8 ist. Die als Bohrung 32 ausgebildete Öffnung 26 mündet im Bereich der Kegelspitze der Bohrung 31 und verbindet somit die Bohrung 31 mit der Farbkammer 22.
Als Vertiefung 27 eignen sich natürlich auch andere Formen, z. B. quaderförmige Vertiefungen oder in Drehrichtung keilförmige zulaufende Flächen, die sowohl zu den inneren und äußeren Stirnflächen 23, 24, 33, 34 der Seitenbacken 7, 8 begrenzt oder offen ausgebildet sein können. Zudem können entlang der Dichtfläche 21 auch mehrere dieser Vertiefungen 27 und Öffnungen 26 angebracht sein.In a second embodiment (Fig. 3 and Fig. 4), the
As a
Weiterhin sind die Seitenbacken 7, 8 an ihren äußeren, der Farbkammer 22 abgewandten Stirnflächen 33, 34 mit Abstreifern 36, 37 versehen, die über die äußere Stirnfläche 33, 34 der Seitenbacken 7, 8 keilförmig in Drehrichtung der Rasterwalze 2 hinaus wirken. Im vorliegenden Beispiel verläuft am einlaufenden Ende des jeweiligen Seitenbackens 7, 8 ein Einschnitt 38 der Tiefe t38 und Breite b38 unterhalb und annähernd parallel zur Dichtfläche 21. Entlang dieses Einschnittes 38 wird der Abstreifer 36, 37 durch Abbiegen eines Teils der Seitenbacken 7, 8 nach außen, d. h. der Farbkammer 22 abgewandten Richtung derart abgebogen, daß eine Innenfläche 39, 41 des Abstreifers 36, 37 über die äußere Stirnfläche 34, 36 der Seitenbacken 7, 8 in einem Überstand ü, z. B. 3 mm, hinausragt. Somit bildet der Abstreifer 36, 37 bezüglich der inneren Stirnfläche 23, 24 der Seitenbacken 7, 8 eine keilförmige Verjüngung.Furthermore, the
Die Funktionsweise der Kammerrakel 1 ist folgendermaßen: Durch nicht dargestellte Haltevorrichtung wird das Kammerrakel 1 an die Rasterwalze 2 angedrückt, so daß die Dichtflächen 21 der Seitenbacken 7, 8 und vorgespanntes Arbeits- bzw. Schließrakelblatt 4, 6 an einer Mantelfläche 42 der Rasterwalze 2 anliegt. Der so gebildeten Farbkammer 22 wird über nicht dargestellte Öffnungen Farbe zu- bzw. abgeführt. Die in der Farbkammer 22 befindliche Farbe strömt durch die Öffnung 26 der Stirnfläche 23, 24 der Seitenbacken 7, 8 in die Vertiefung 27 der Dichtfläche 21. Durch die Drehung der Rasterwalze 2 wird die Farbe außerhalb der Vertiefung 27 in einen sich bildenden Spalt zwischen Dichtfläche 21 und Rasterwalze 2 transportiert. Die Vertiefung 27 bildet somit eine Schmiertasche eines hydrodynamischen, bzw. wenn die Farbkammer 22 mit Überdruck betrieben wird, eines hydrostatischen Gleitlagers, wobei die Farbe als Schmiermittel dient.
Tritt Farbe außerhalb der äußeren Stirnfläche 33, 34 der Seitenbacken 7, 8 aus dem Spalt zwischen Rasterwalze 2 und Dichtfläche 21 aus, sammelt sich diese als Wulst auf der Rasterwalze 2 und wird mittels des Abstreifers 37, 37 zu den inneren Stirnflächen 23, 24 der Seitenbacken 7, 8 transportiert. Entlang dieser Stirnflächen 23, 24 wird diese ausgetretene Farbe zu einem nicht dargestellten Farbtrichter bzw. Rücklaufbehälter gefördert.The operation of the
