Abstract

The ink box comprises an ink controlled feed device which comprises several zone-side controlled feed components tightly arranged next to one another. The controlled feed components have support and controlled feed areas, the support areas permanently directly or indirectly locating under spring pressure on an ink box roller. By rotation of the controlled feed components the controlled feed areas are adjustable to different ink gap thicknesses. The controlled feed components (11) commencing in the area of the ink thickness 0 have a flattening (20) which runs as a secant and in the area of the ink gap thickness 0 forms a wipe-off edge. The flattening extends over the length of the controlled feed area (18). The support areas (17) locating directly or indirectly on the ink box roller (4) have a radius r of approximately 3 mm.

Description

Die Erfindung bezieht sich auf einen Farbkasten für Rotationsdruckmaschinen mit einer Farbdosiereinrichtung, die aus einer Vielzahl von dicht nebeneinander angeordneten zonenbreiten Dosierelementen besteht, die Stütz- und Dosierbereiche aufweisen und deren Stützbereiche unter Federdruck an einer Farbkastenwalze ständig direkt oder indirekt anliegen, wobei durch Verdrehen der Dosierelemente die Dosierbereiche auf unterschiedliche Farbspaltdicken einstellbar sind.The invention relates to an ink fountain for rotary printing presses with a Color metering device, which consists of a large number of closely arranged zone-wide metering elements, which have support and metering areas and their Support areas under spring pressure on an ink fountain roller, either directly or indirectly are applied, the metering areas being opened by rotating the metering elements different ink gap thicknesses can be set.

Die DE 29 23 678 C2 zeigt eine derartige Ausgestaltung eines Farbkastens, bei der die Entstehung von farbfreien Streifen auf der Farbkastenwalze aufgrund der ständigen Anlage der Stützbereiche verhindert werden soll. Hierzu ist jedem Dosierelement ein Dosiermesser zugeordnet, das über die Lange des Dosierelements reicht. Hiermit soll ein axiales Ausbreiten der Farbe nach dem Dosierbereich erreicht werden, so daß diese über die gesamte Zonenbreite gleichmäßig verteilt ist. Bei dieser bekannten Lösung stehen die Dosierelemente unter einem konstanten Federdruck, der beim Betrieb der Maschine, d. h. bei einer Drehbewegung der Farbkastenwalze, zu einem Verschleiß der die Dosierelemente abdeckenden Folie führen kann. Der Federdruck ist hierbei so bemessen, daß er den durch die Drehbewegung der Farbkastenwalze auftretenden hydrodynamischen Druck überwindet und eine sichere direkte oder indirekte Anlage der Dosierelemente an der Mantelfläche der Farbkastenwalze gewährleistet.DE 29 23 678 C2 shows such an embodiment of a color box, in which the Formation of color-free stripes on the ink fountain roller due to the constant Creation of the support areas should be prevented. For this purpose, each dosing element is one Assigned metering knife, which extends over the length of the metering element. Hereby a axial spreading of the color can be achieved according to the metering range, so that this over the entire zone width is evenly distributed. In this known solution, the Dosing elements under a constant spring pressure, which during operation of the machine, d. H. when the ink fountain roller rotates, the wear of the Dosing elements covering foil can lead. The spring pressure is dimensioned here that he the hydrodynamic occurring by the rotation of the ink fountain roller Pressure overcomes and a safe direct or indirect installation of the dosing elements the outer surface of the ink fountain roller guaranteed.

Ausgehend von diesem Stand der Technik ist es die Aufgabe vorliegender Erfindung, die hydrodynamischen Kräfte bzw. den Federdruck auf die Dosierelemente und damit Verschleiß und Wärmeentwicklung zu verringern.Based on this prior art, it is the object of the present invention that hydrodynamic forces or the spring pressure on the dosing elements and thus Reduce wear and heat generation.

Gemäß der Erfindung wird die Aufgabe dadurch gelöst, daß die Dosierelemente beginnend im Bereich der Farbspaltdicke 0 eine Abflachung aufweisen, die als Sekante verläuft und im Bereich der Farbspaltdicke 0 eine Abstreifkante bildet. Mit dieser Abstreifkante wird erreicht, daß der auftretenden hydrodynamische Druck wesentlich geringer ist und daß dem gemäß der benötigte Federdruck reduziert werden kann. Hierdurch lassen sich Verschleißerscheinungen an der Folie minimieren und gleichzeitig wird eine wesentlich geringere Wärmeentwicklung im Bereich der Farbe erreicht.According to the invention the object is achieved in that the metering elements have a flattening beginning in the area of the ink gap thickness 0, which is called the secant runs and forms a scraping edge in the area of the ink gap thickness 0. With this Scraper edge is achieved that the occurring hydrodynamic pressure significantly is lower and that can be reduced according to the required spring pressure. This minimizes signs of wear on the film and at the same time a significantly lower heat development in the area of the color is achieved.

Eine vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß sich die Abflachung über die Länge des Dosierbereichs erstreckt. Hierdurch wird bei Null-Stellung eines Dosierelements der hydrodynamische Druck nicht erhöht.An advantageous embodiment of the invention is characterized in that the Flattening extends over the length of the dosing area. This will help The zero position of a dosing element does not increase the hydrodynamic pressure.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß die direkt oder indirekt an der Farbkastenwalze anliegenden Stützbereiche einen Radius von etwa 3 mm aufweisen. Durch diesen geringen Radius wird die Keilwirkung zwischen Dosierelement und Mantelfläche der Farbkastenwalze verringert, so daß auch gleichzeitig der hydrodynamische Druck abgebaut werden kann. Auch hiermit läßt sich der Federdruck und somit der Verschleiß an der Folie reduzieren.A further advantageous embodiment of the invention is characterized in that the support areas directly or indirectly on the ink fountain roller a radius of about 3 mm. Due to this small radius, the wedge effect between Dosing element and lateral surface of the ink fountain roller reduced, so that at the same time the hydrodynamic pressure can be reduced. With this, too Reduce spring pressure and thus wear on the film.

It shows:
Fig. 1
a cross section through an ink fountain with ink fountain roller,
Fig. 2
an enlarged section of the color metering device.

Der Farbkasten 1 nach Fig. 1 besteht im wesentlichen aus einer Bodenplatte 2 und den Seitenwänden 3, die den Farbraum stirnseitig abschließen. Der Farbkasten 1 ist einer Farbkastenwalze 4 zugeordnet, die die benötigte Farbmenge dem Farbwerk der Rotationsdruckmaschine zuführt. Oberhalb der Bodenplatte 2 sind nebeneinander Druckleisten 5 vorgesehen, an denen die Farbdosiereinrichtung 6 angeordnet ist. Die Druckleisten 5 und die Farbdosiereinrichtungen 6 sind in dichter Folge über die Länge des Farbkastens 1 nebeneinander angeordnet. Hierbei stützen sich die Druckleisten 5 an Druckfedern 7 ab und werden von Schrauben 8 lose gehalten. Die Druckleisten 5 und die Farbdosiereinrichtungen 6 sind von einer Folie 9 abgedeckt, die ein Verschmutzen durch die Druckfarbe 10 verhindert.1 consists essentially of a base plate 2 and the Side walls 3 which close off the color space at the end. The ink fountain 1 is one Ink fountain roller 4 assigned that the required amount of ink to the inking unit Rotary press feeds. Above the base plate 2 are next to each other Pressure bars 5 are provided, on which the ink metering device 6 is arranged. The Pressure bars 5 and the ink metering devices 6 are in close succession over the length of the Color box 1 arranged side by side. The pressure bars 5 are supported here Compression springs 7 and are held loose by screws 8. The pressure bars 5 and the Ink metering devices 6 are covered by a film 9 which is contaminated by the ink 10 prevented.

Die Farbdosiereinrichtung 6 besteht aus einer Vielzahl von dicht nebeneinander angeordneten zonenbreiten Dosierelementen 11, die jeweils über einen Stellarm 12, einem Lenker 13 und einer Stellmutter 14 verschwenkt werden können. Die Stellmutter 14 läßt sich über eine Stellschraube 15 in Langsrichtung bewegen, wobei der Antrieb der Stellschraube über einen Stellmotor 16 erfolgt.The color metering device 6 consists of a large number of closely adjacent one another arranged zone-wide metering elements 11, each via an actuating arm 12, a Handlebar 13 and an adjusting nut 14 can be pivoted. The adjusting nut 14 leaves move about a set screw 15 in the longitudinal direction, the drive of the Set screw via an actuator 16 is carried out.

Jedes Dosierelement 11 weist im gezeigten Ausführungsbeispiel an seinem Umfang z. B. zwei schmale Stützbereiche 17 auf, zwischen denen ein exzentrisch verlaufender Dosierbereich 18 vorgesehen ist. Durch Verdrehen des Dosierelements 11 im Uhrzeigersinn gemäß Fig. 2, entsteht ein größer werdender Spalt zwischen Stützbereich 17 und Dosierbereich 18, in den sich die elastische Folie einlegt, so daß beim Drehen der Farbkastenwalze 4 auf deren Mantelfläche 19 ein Farbstreifen entsprechender Dicke und Breite entsteht. Über diese Farbspaltdicke läßt sich somit die in das Farbwerk zu transportierende Farbe zonenweise einstellen.In the exemplary embodiment shown, each metering element 11 has z. B. two narrow support areas 17, between which an eccentric Dosing area 18 is provided. By rotating the metering element 11 in Clockwise according to Fig. 2, there is an increasing gap between Support area 17 and metering area 18, in which the elastic film is inserted, so that at Rotating the ink fountain roller 4 on its outer surface 19 corresponding to a color strip Thickness and width arise. About this ink gap thickness can thus in the inking unit Adjust the color to be transported zone by zone.

Im gezeigten Ausfürungsbeispiel gemäß Fig. 2 ist das Dosierelement 11 in seiner Null-Stellung wiedergegeben, d. h. Stützbereich 17 und Dosierbereich 18 befinden sich auf einer Ebene, so daß kein Farbspalt vorhanden ist. In dieser Stellung ist der hydrodynamische Druck der Farbe 10 am höchsten. Gemäß der vorliegenden Erfindung ist in diesem Bereich eine Abflachung 20 vorgesehen, die als Sekante unter einem bestimmten Winkel α verläuft. Hierdurch bildet sich am Dosierelement 11, im Bereich der Farbspaltdicke 0 eine Abstreifkante 21, über die sich die elastische Folie 9 legt. Durch die Abstreifkante 21 wird die Farbe restlos von der Mantelfläche 19 der Farbkastenwalze 4 entfernt, ohne daß ein hoher Staudruck der Druckfarbe 10 entstehen kann. Hierdurch ist es möglich, die Druckfeder 7 entsprechend auszulegen, so daß der Federdruck auf das Dosierelement 11 und somit gegen die Mantelfläche 19 der Farbkastenwalze 4 verringert wird.In the exemplary embodiment shown in FIG. 2, the metering element 11 is in its Played zero position, d. H. Support area 17 and metering area 18 are located on one level so that there is no color gap. In this position the Color 10 hydrodynamic pressure highest. According to the present invention a flattening 20 is provided in this area, which as a secant under a certain angle α. This forms on the dosing element 11 in the area the ink gap thickness 0 a wiping edge 21 over which the elastic film 9 is placed. By the scraper edge 21 is the color of the outer surface 19 of the Ink fountain roller 4 removed without a high back pressure of the printing ink 10 can. This makes it possible to design the compression spring 7 accordingly, so that the Spring pressure on the metering element 11 and thus against the lateral surface 19 of the Ink fountain roller 4 is reduced.

Als Ausgestaltungsvariante kann sich die Abflachung 20 über die Länge des Dosierbereichs 18 erstrecken, so daß die Stützbereiche kreisförmig ausgebildet sein können. Weiterhin ist es möglich, den Staudruck der Druckfarbe 10 dadurch zu reduzieren, daß das Dosierelement 11 so ausgebildet wird, daß die direkt oder indirekt an der Farbkastenwalze 4 anliegenden Stützbereiche 17 einen Radius r von etwa 3 mm aufweisen. Auch hierdurch läßt sich der Stauwinkel für die Druckfarbe 10 verringern, so daß der Anstelldruck an die Mantelfläche 19 der Farbkastenwalze 4 vermindert wird und ein Verschleiß der Folie 9 bzw. eine Erwärmung reduziert werden kann. As a design variant, the flattening 20 can extend over the length of the Dosing area 18 extend so that the support areas are circular can. It is also possible to thereby increase the back pressure of the printing ink 10 reduce that the metering element 11 is designed so that the directly or indirectly the ink fountain roller 4 adjacent support areas 17 a radius r of about 3 mm exhibit. This also makes it possible to reduce the jamming angle for the printing ink 10, so that the contact pressure on the lateral surface 19 of the ink fountain roller 4 is reduced and wear of the film 9 or heating can be reduced.
