Description

Vorliegende Erfindung betrifft einen Farbkasten einer Druckmaschine und eine Farbkastenwalze für einen solchen Farbkasten.The present invention relates to an ink fountain of a printing machine and an ink fountain roller for such an ink fountain.

Es gibt zwei Typen von Farbkästen. Bei dem einen bilden ein oder mehrere Dosierelemente, z. B. ein Farbmesser oder mehrere Farbschieber, zusammen mit der Farbkastenwalze einen Dosierspalt. Bei dem anderen Typ bildet eine Folie, welche sich zwischen den Dosierelementen und der Farbkastenwalze befindet, zusammen mit letzterer den Dosierspalt. Unabhängig vom Farbkastentyp sind die den Dosierspalt bildenden Bauteile, welche mit der Druckfarbe in Kontakt kommen, bei der Verarbeitung von stark abrasiv wirkenden Druckfarben einem übermäßigen Verschleiß ausgesetzt. Stark abrasiv wirkende Druckfarben sind erfahrungsgemäß UV-Farben, Deckweiß-Farben und Mattlacke. Für die Abrasionswirkung ursächlich ist beispielsweise bei UV-Farben deren Neigung, infolge des im Dosierspalt wirksamen hydrodynamischen Druckes zu polymerisieren und dabei in Partikelform auszuhärten. Die Partikel können derart anwachsen, dass sie sich im Eingang des Dosierspalts zu einer abrasiven Schicht aufstauen.There are two types of color boxes. In one form one or more dosing, z. As a color meter or more color slider, together with the ink fountain roller a metering. In the other type forms a film, which is located between the metering and the ink fountain roller, together with the latter the dosing. Regardless of the color box type, the components forming the metering gap, which come into contact with the printing ink, are exposed to excessive wear during the processing of highly abrasive printing inks. According to experience, highly abrasive printing inks are UV inks, opaque white inks and matt coatings. The cause of the abrasion effect, for example, in the case of UV inks, is their tendency to polymerize as a result of the hydrodynamic pressure effective in the metering gap and to harden in particle form. The particles can grow in such a way that they build up in the entrance of the metering gap to an abrasive layer.

In DE 199 14 179 A1 ist eine Farbkastenfolie mit drahtförmigen Körpern beschrieben, welche den Verschleißwiderstand erhöhen. Bei einem Ausführungsbeispiel dieser Folie sind die drahtförmigen Körper auf einer Trägerlage befestigt und mit einer Decklage abgedeckt, derart, dass zwischen den drahtförmigen Körpern linienförmige Rillen verlaufen.In DE 199 14 179 A1 is described a color box film with wire-shaped bodies, which increase the wear resistance. In one embodiment of this film, the wire-shaped bodies are mounted on a carrier layer and covered with a cover layer, such that line-shaped grooves run between the wire-shaped bodies.

Der Erfindung liegt die Aufgabe zugrunde, einen auch bei Verarbeitung von stark abrasiven Druckfarben hinreichend verschleißbeständigen Farbkasten zu schaffen.The invention has for its object to provide a sufficiently wear-resistant even when processing highly abrasive inks ink fountain.

Diese Aufgabe wird durch einen Farbkasten mit den Merkmalen des Anspruchs 1 gelöst. Der erfindungsgemäße Farbkasten einer Druckmaschine umfasst ein Bauteil mit einer Tragfläche zum Tragen der Druckfarbe und in die Tragfläche eingebrachten Näpfchen.This object is achieved by a paint box with the features of claim 1. The ink fountain according to the invention of a printing machine comprises a component having a support surface for supporting the printing ink and introduced into the support surface wells.

Es hat sich in Versuchen herausgestellt, dass durch die Näpfchen Partikel, wie die erwähnten UV-Farben-Partikel, aus dem Dosierspalt gespült werden. Das den Dosierspalt begrenzende Bauteil, z. B. eine Farbkastenfolie oder ein Dosierelement, ist nicht mehr der Schleifwirkung sich im Dosierspalt stauender Partikel ausgesetzt, wodurch sich die Standzeit verlängert.It has been found in experiments that are flushed through the wells particles, such as the mentioned UV ink particles from the dosing. The dosing gap limiting component, eg. As an ink fountain pen or a metering, is no longer exposed to the abrasive effect in the metering gap jamming particles, thereby extending the life.

Die Öffnung des jeweiligen Näpfchens hat, im Gegensatz zu einer linienförmigen Rille, einen rundum in sich geschlossenen Rand.The opening of the respective cup has, in contrast to a line-shaped groove, a completely self-contained edge.

In den Unteransprüchen sind Weiterbildungen des erfindungsgemäßen Farbkastens genannt.In the dependent claims developments of the ink fountain according to the invention are called.

Bei einer Weiterbildung bildet die Tragfläche zwischen den Näpfchen liegende Stege, die einen höheren Flächenanteil als Näpfchen einnehmen. Demgemäß ist pro Flächeneinheit die Summe der Flächen der Stege größer als die Summe der Fläche der Näpfchen.In a further development, the support surface forms webs lying between the wells, which occupy a higher area proportion than wells. Accordingly, the sum of the areas of the lands per unit area is greater than the sum of the area of the cells.

Bei einer weiteren Weiterbildung weisen die Näpfchen eine Öffnung mit einer Öffnungsweite auf, die weniger als 1 Millimeter beträgt. Bei der Öffnungsweite kann es sich um die Seitenlänge eines Quadrats handeln, wenn das jeweilige Näpfchen die Form einer Hohlpyramide hat und die Öffnung demzufolge quadratisch ist.In a further development, the wells have an opening with an opening width which is less than 1 millimeter. The opening width may be the side length of a square, if the respective well has the shape of a hollow pyramid and the opening is therefore square.

Bei einer weiteren Weiterbildung ist die Öffnung rund und ist die Öffnungsweite ein Durchmesser. Diese Geometrie ist gegeben, wenn das jeweilige Näpfchen die Form einer Kalotte oder eines Hohlkegels hat.In a further development, the opening is round and the opening width is a diameter. This geometry is given if the respective cup has the shape of a dome or a hollow cone.

Bei einer weiteren Weiterbildung weisen die Näpfchen eine Tiefe auf, die höchstens 50 % der Öffnungsweite beträgt. Demgemäß ist das jeweilige Näpfchen höchstens halb so tief wie breit.In a further development, the wells have a depth which is at most 50% of the opening width. Accordingly, the respective well is at most half as deep as it is wide.

Bei einer weiteren Weiterbildung sind die Näpfchen in einem regelmäßigen Raster angeordnet. Beispielsweise können die Näpfchen schachbrettmusterartig angeordnet sein.In a further development, the wells are arranged in a regular grid. For example, the cups may be arranged like a checkerboard pattern.

Bei einer weiteren Weiterbildung ist das die Näpfchenstruktur aufweisende Bauteil eine Farbkastenwalze. Vorzugsweise handelt es sich bei der Farbkastenwalze um eine solche, die periodisch von einer Heberwalze kontaktiert wird.In a further development, the component having the cell structure is an ink fountain roller. Preferably, the ink fountain roller is one which is periodically contacted by a lift roller.

Zur Erfindung gehören auch eine Farbkastenwalze, welche eine Tragfläche zum Tragen der Druckfarbe und in die Tragfläche eingebrachte Näpfchen aufweist, und eine Druckmaschine, welche mit einem erfindungsgemäß oder einer der Weiterbildungen entsprechend ausgebildeten Farbkasten ausgestattet ist.The invention also includes an ink fountain roller having a support surface for supporting the ink and introduced into the support surface wells, and a printing machine, which is equipped with an inventively or one of the developments correspondingly trained ink fountain.

Gemäß einer Weiterbildung der Farbkastenwalze bilden die darin eingebrachten Näpfchen ein regelmäßiges Raster. Abweichend von dieser bevorzugten Weiterbildung können die Näpfchen aber auch in unregelmäßiger bzw. stochastischer Verteilung in die Umfangsoberfläche der Farbkastenwalze eingebracht sein.According to a development of the ink fountain roller, the cups introduced therein form a regular grid. Deviating from this preferred development, however, the wells can also be introduced into the circumferential surface of the ink fountain roller in an irregular or stochastic distribution.

Weitere konstruktiv und funktionell vorteilhafte Weiterbildungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels und der dazugehörigen Zeichnung.Other constructive and functional advantageous developments of the invention will become apparent from the following description of a preferred embodiment and the accompanying drawings.

a color box with a ink fountain roller and
FIG. 2
a surface structure of the ink fountain roller of Figure 1.

Figur 1 zeigt ausschnittsweise eine Druckmaschine 1 zum Bedrucken von Bogen im Offsetdruck. Der Ausschnitt zeigt ein Farbwerk, welches einen Farbkasten 2 mit einer Farbkastenwalze 4 und eine Heberwalze 5 umfasst. Der Farbkasten 2 nimmt einen keilförmigen Vorrat an Druckfarbe 3 auf und ist mit einer Dosiereinrichtung 6 ausgestattet, die in individuell steuerbare Farbzonen über die Druckbreite unterteilt ist. Während des Druckbetriebs legt sich die Heberwalze 5 periodisch an die Farbkastenwalze 4, um von dieser die Druckfarbe abzunehmen. Die Farbkastenwalze 4 ist umfangsseitig mit einer makroskopischen Näpfchenstruktur versehen, die in Figur 2 im vergrößerten Schnitt dargestellt ist.Figure 1 shows a detail of a printing machine 1 for printing sheets in offset printing. The detail shows an inking unit, which comprises a paint box 2 with a ink fountain roller 4 and a lifting roller 5. The ink fountain 2 receives a wedge-shaped supply of printing ink 3 and is equipped with a metering device 6, which is subdivided into individually controllable ink zones over the printing width. During the printing operation, the squeegee roller 5 periodically applies to the ink fountain roller 4 to remove the ink therefrom. The ink fountain roller 4 is circumferentially with a provided macroscopic cell structure, which is shown in Figure 2 in enlarged section.

Figur 2 zeigt, dass die Umfangsfläche der Farbkastenwalze 4 eine Tragfläche 7 bildet, welche aus maschenartig ineinander übergehenden Stegen 8 besteht. In die Umfangsfläche sind entsprechend einem Raster 11 Näpfchen 9 z. B. per Lasergravur eingebracht. Das Raster 11 hat eine Rasterweite entsprechend einem Mittenabstand A der Näpfchen 9. Der Mittenabstand A kann z. B. 400 µm bis 900 µm betragen. Ein von Näpfchen zu Nachbarnäpfchen zu messender Näpfchenabstand S, welcher der Breite der Stege 8 entspricht, kann z. B. 200 µm bis 600 µm betragen. Die Näpfchen 9 haben jeweils eine Öffnung 10, deren Durchmesser D 200 µm bis 300 µm betragen kann. Die Tiefe t des jeweiligen Näpfchens 9 beträgt mindestens 10 µm.Figure 2 shows that the peripheral surface of the ink fountain roller 4 forms a support surface 7, which consists of web-like webs 8 merging into one another. In the peripheral surface 11 cells 9 z. According to a grid. B. introduced by laser engraving. The grid 11 has a grid width corresponding to a center distance A of the wells 9. The center distance A can, for. B. 400 microns to 900 microns. One of cups to Nachbaräpfchen to be measured cell spacing S, which corresponds to the width of the webs 8, z. B. 200 microns to 600 microns. The wells 9 each have an opening 10 whose diameter D may be 200 microns to 300 microns. The depth t of the respective well 9 is at least 10 microns.

Beispielsweise beträgt bei einem ca. 76 % betragenden Trag- oder Flächenanteil der Stege 8 oder Tragfläche 7 der Mittenabstand A ca. 500 µm, der Näpfchenabstand S ca. 280 µm, der Durchmesser D ca. 250 µm, wobei die Tiefe t ca. 15 µm beträgt.For example, with an approximately 76% amount of support or surface portion of the webs 8 or wing 7, the center distance A is about 500 microns, the cell spacing S about 280 microns, the diameter D about 250 microns, wherein the depth t about 15 μm.

Bevorzugt wird eine Variante mit einem ca. 88 % betragenden Trag- oder Flächenanteil der Stege 8 oder Tragfläche 7, wobei der Mittenabstand A ca. 770 µm, der Näpfchenabstand S ca. 560 µm, der Durchmesser D ca. 275 µm und die Tiefe t ca. 15 µm beträgt.Preferably, a variant with an approximately 88% amount of support or surface portion of the webs 8 or wing 7, wherein the center distance A about 770 microns, the cell spacing S about 560 microns, the diameter D about 275 microns and the depth t about 15 microns.

Die in die Farbkastenwalze 4 eingebrachten Näpfchen 9 verhindern ein Zusetzen des zwischen der Farbkastenwalze 4 und der Dosiereinrichtung 6 oder - im Falle einer zwischen der Farbkastenwalze 4 und der Dosiereinrichtung 6 eingefügten Farbkastenfolie - zwischen ebendieser Farbkastenfolie und der Farbkastenwalze 4 vorhandenen Farbspalts durch Schmutz- und Farbpartikel. Die Näpfchen 9 verhindern ein Verklumpen der Druckfarbe 3 im Farbspalt und reduzieren den Verschleiß der Farbkastenwalze 4, welchen die Schmutz-oder Farbpartikel oder -klumpen sonst bewirken würden. Dadurch erhöht sich die Reproduziergenauigkeit der Einstellung der Dosiereinrichtung 6 und werden Qualitätsschwankungen des Druckbilds verringert. Die Farbkastenwalze 4 ist besonders gut für den Fall geeignet, in welchem es sich bei der Druckfarbe 3 um eine UV-Farbe handelt.The introduced into the ink fountain roller 4 cups 9 prevent clogging of between the ink fountain roller 4 and the metering device 6 or - in the case of an inserted between the ink fountain roller 4 and the metering device 6 ink fountain pen - between ebendieser ink fountain film and the ink fountain roller 4 existing color gap by dirt and ink particles , The cups 9 prevent clumping of the ink 3 in the ink gap and reduce the wear of the ink fountain roller 4, which would otherwise cause the dirt or paint particles or lumps. As a result, the reproducibility of the adjustment of the metering device 6 increases and quality fluctuations of the printed image are reduced. The ink fountain roller 4 is particularly well suited to the case where the ink 3 is a UV ink.
