Description
Die Erfindung betrifft eine Rasterwalze innerhalb eines Auftragswerkes einer Rotationsdruckmaschine nach dem Oberbegriff des Hauptanspruches.The invention relates to an anilox roller within an application unit of a rotary printing press according to the preamble of the main claim.
Eine Rasterwalze, auch Näpfchenwalze genannt, dieser Art ist aus der DE 39 38 449 C2 bekannt, welche auf dem Zylinder- oder Walzenkern eine poröse, volumenveränderbare Zwischenschicht aufweist. Auf dieser Zwischenschicht ist eine Schicht mit temperaturabhängigem Formgedächnis angeordnet. Diese Ausbildung dient der Veränderung der Dosiermenge von Farbe als verwendetes flüssiges Medium, indem in der Schicht unter thermischer Einwirkung die Form der Näpfchen verändert bzw. völlig beseitigt wird.An anilox roller, also called a cup roller, of this type is known from DE 39 38 449 C2 known, which on the cylinder or roller core a porous, volume-changeable Has intermediate layer. On this intermediate layer is a layer with a temperature-dependent Shape memory arranged. This training serves to change the dosing quantity of color as the liquid medium used, in the layer under thermal Action changes the shape of the wells or is completely eliminated.
Aus der DE 44 08 615 C2 ist weiterhin eine Näpfchenwalze in einem Auftragswerk bekannt, deren Grundkörper eine konzentrisch angeordnete Schicht aus einem piezoelektrischen Material trägt und auf der wiederum eine elektrisch leitfähige Oberflächenschicht konzentrisch angeordnet ist. Grundkörper und Oberflächenschicht sind schaltungstechnisch mit einer einstellbaren Spannungsquelle verbunden. Durch Zuschalten einer Spannung wird unter Ausnutzung der Elektrostriktion bzw. des inversen piezoelektrischen Effektes eine Kompression oder eine Dilatation des Näpfchenvolumes bewirkt.From DE 44 08 615 C2 a well roller in an application unit is also known, whose main body is a concentrically arranged layer made of a piezoelectric Material carries and on the in turn an electrically conductive surface layer is arranged concentrically. The basic body and surface layer are circuitry-related connected to an adjustable voltage source. By switching on a voltage is using the electrostriction or the inverse piezoelectric effect causes compression or dilation of the well volume.
Die aufgeführten Rasterwalzen besitzen in ihrem Aufnahmevolumen veränderbare Näpfchen.The listed anilox rollers have changeable cups in their receiving volume.
Aus der EP 0 190 390 B1 ist eine weitere Rasterwalze als Dosierwalze bekannt, die auf einem Stahlkern eine Rasterstruktur mit einer ersten Beschichtung (oleophiles/hydrophobes Material, z.B. Kupfer) und einer zweiten äußeren Beschichtung in Form einer mikroporösen Keramik besitzt. From EP 0 190 390 B1 a further anilox roller is known as a metering roller, which is based on a steel core a grid structure with a first coating (oleophilic / hydrophobic Material, e.g. Copper) and a second outer coating in the form of a microporous Owns ceramics.
Nachteilig bei dieser Ausführung ist, daß das Volumen der Näpfchen nicht mehr veränderbar ist. Das durch die Herstellung (z.B. Ätzen, Gravieren) einmal erzeugte Raster ist auf Form und Größe der Näpfchen festgelegt. Dies ist bei Verarbeitung von flüssigen Medien mit unterschiedlicher Viskosität oder bestimmten chemischen Zusammensetzungen von Nachteil. Eine Veränderung der Dosiermenge ist abhängig vom zuverarbeitenden flüssigen Medium nur durch einen Austausch der Rasterwalzen durch eine neue Rasterwalze mit anderer Struktur bzw. anderen Eigenschaften möglich. Ein Walzentausch ist jedoch aufwendig, da Stillstandzeiten entstehen.A disadvantage of this design is that the volume of the cells can no longer be changed is. The grid created once by the production (e.g. etching, engraving) is open The shape and size of the cells are determined. This is when processing liquid media with different viscosity or certain chemical compositions of Disadvantage. A change in the dosage depends on the liquid to be processed Medium only by replacing the anilox rollers with a new anilox roller other structure or other properties possible. However, changing the rollers is complex, because downtimes arise.
Der Erfindung liegt die Aufgabe zugrunde, eine Rasterwalze mit Näpfchen (Vertiefungen) und Stegen (Erhöhungen) in einem Auftragswerk so auszubilden, daß die Menge des aufzunehmenden flüssigen Mediums beeinflußbar ist.The invention has for its object to provide an anilox roller with cups (depressions) and webs (increases) in a commissioned work so that the amount of the to be included liquid medium can be influenced.
Erfindungsgemäß wird die Aufgabe durch die im Hauptanspruch aufgeführten Merkmale gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention the object is achieved by the features listed in the main claim solved. Further training results from the subclaims.
Mit der erfindungsgemäßen Lösung ist die universelle Verarbeitung von flüssigen Medien mit unterschiedlicher Viskosität und insbesondere eine exakte Dosierung der Flüssigkeitsmenge möglich. Die Rasterwalze ist innerhalb eines Auftragswerkes in einer Rotationsdruckmaschine in Verbindung mit einem Dosiersystem, z.B. einer Kammerakel oder einer weiteren Walze (Zwei- Walzenwerk), einsetzbar. Sie gestattet die Verarbeitung von flüssigen Medien, wie beispielsweise Flexodruckfarbe, pigmenthaltiger Effektdruckfarbe und Dispersionslack, wobei insbesondere Medien auf Wasserbasis Verwendung finden. Die Näpfchen der Oberfläche der Rasterwalze sind mit einem Füllstoffverschließbar, überschüssiger Füllstoff ist abrakelbar und die Näpfchen sind vollständig oder teilweise in ihrem Aufnahmevolumen freilegbar. Diese Rasterwalze ist sowohl in Druckwerken als auch in Weiterverarbeitungseinheiten zur Druckveredelung, z.B. in Lackiereinheiten, einsetzbar. Mögliche, durch Walzenwechsel bedingte, Stillstandszeiten werden reduziert, da ein Austausch von Rasterwalzen mit größerer oder kleinerer Struktur bzw. anderen Eigenschaften hinfällig ist. With the solution according to the invention is the universal processing of liquid media with different viscosity and in particular an exact dosage of the amount of liquid possible. The anilox roller is within a job in a rotary printing press in connection with a dosing system, e.g. a chamber oracle additional roller (two-roller mill), can be used. It allows the processing of liquid Media such as flexographic printing ink, pigment-containing effect printing ink and Dispersion varnish, with water-based media in particular being used. The Cups on the surface of the anilox roller can be closed with a filler, excess Filler can be scraped off and the cells are completely or partially in their Exposure volume exposed. This anilox roller is used both in printing units and in Processing units for print finishing, e.g. Can be used in painting units. Possible downtimes due to roller changes are reduced because of an exchange of anilox rollers with a larger or smaller structure or other properties is obsolete.

festgelegte Grundraster 7 der Rasterwalze 3 wird nach Kontakt mit dem Formzylinder 2
von dem in dem Näpfchen 5 möglicherweise noch anhaftenden Bestandteilen des flüssigen
Mediums in einer Regenerationseinrichtung 8 gereinigt, so daß die Rasterwalze 3 auf ihr
Grundraster 7 zurückgeführt wird. Während der Rotation der Rasterwalze 3 werden an der
nachgeordneten Antragseinrichtung 9 die Näpfchen 5 befüllt und gleichzeitig werden die
Stege 6 vorzugsweise durch ein Rakel abgestriffen. In Drehrichtung der Rasterwalze 3 folgt
danach die Abtragseinrichtung 10, welche die Tiefe der Näpfchen 5 auf einen vorgestimmten
Wert freilegt. Dazu wird ein Teil der befüllten Substanz 11 aus den Näpfchen 5 wieder
entfernt, so daß die Volumina der Näpfchen 5 in ihrem Aufnamevermögen begrenzt sind.
Erreicht die Rasterwalze 3 das Dosiersystem 4, so wird in den freigelegten Bereichen der
Näpfchen 5 das zuverarbeitende Medium aufgenommen und als Tropfen 13 an den Formzylinder
2 übertragen.
