Abstract

Dieser Farbkasten (1) besitzt eine Farbdosiereinrichtung (4) für eine zonenweise Einstellung des jeweiligen Farbspaltes unter Zwischenschaltung einer elastischen Folie (8). Durch die Drehung der Farbkastenwalze (2), an der die elastische Folie (8) anliegt, tritt an der Folie (8) ein gewisser Verschleiß auf, wodurch ein häufiges Auswechseln derselben erforderlich wird. Um ihre Benutzungsdauer zu verlängern, ist im oberen Bereich des Farbkastens (1) eine Haltevorrichtung (14 bis 20) angebracht, an der die elastische Folie (8) nachstellbar befestigt ist, wobei nach dem Nachstellen jeweils ein neuer, nichtabgenutzter Teil der Folienoberfläche an der Farbkastenwalze (2) anliegt. Das Nachstellen erfolgt in der dargestellten Ausführung durch Drehen der Spannspindel (14), die einen Längsschlitz (15) zum Einhängen der elastischen Folie (8) aufweist.This ink fountain (1) has an ink metering device (4) for zone-by-zone adjustment of the respective ink gap with the interposition of an elastic film (8). As a result of the rotation of the ink fountain roller (2) against which the elastic film (8) rests, a certain amount of wear occurs on the film (8), which necessitates frequent replacement. In order to extend their service life, a holding device (14 to 20) is attached in the upper area of the ink fountain (1), to which the elastic film (8) is adjustably fastened, with a new, unused part of the film surface on each after the readjustment Ink fountain roller (2) rests. The adjustment is carried out in the illustrated embodiment by turning the clamping spindle (14), which has a longitudinal slot (15) for hanging the elastic film (8).

Description

Die Erfindung betrifft einen Farbkasten für Offset- oder Hochdruckmaschinen mit einer Farbdosiereinrichtung, über die in Achsrichtung der Farbkastenwalze zonenweise der jeweilige Farbspalt einstellbar ist, wobei die Farbdosiereinrichtung über eine elastische Folie an die Farbkastenwalze anstellbar und von der am oberen Rand des Farbkastens leicht herausnehmbar befestigten elastischen Folie abgedeckt ist.The invention relates to an ink fountain for offset or high-pressure machines with an ink metering device, by means of which the respective ink gap can be adjusted in zones in the axial direction of the ink fountain roller, the ink metering device being adjustable to the ink fountain roller via an elastic film and fastened by the elastic fastener which can be easily removed from the upper edge of the ink fountain Foil is covered.

Eine bekannte Ausführung (US-PS 2 382 103) verwendet zum Befestigen der Folie am Farbkasten Federspangen, mit denen die Folie am oberen Rand des Farbkastens festgeklemmt wird. Die hier zur Verwendung kommenden Folien sind relativ steif und müssen deshalb der Farbkastenform durch Knicken angepaßt werden. Nach einer gewissen Laufzeit ist die Folie an ihrer Anlagefläche an der Farbkastenwalze abgenutzt und muß ausgetauscht werden. Der durch die Farbkastenwalze eingeschliffene Kreisabschnitt darf nicht ein solches Ausmaß annehmen, daß der vordere Folienbereich abgetrennt würde, weil sonst eine Verschmutzung der Farbdosiereinrichtung einträte. Der Nachteil der bekannten Ausführung ist, daß zum Auswechseln der Folie immer der Farbkasten entleert werden muß und daß jeweils eine neue Folie benötigt wird.A known embodiment (US Pat. No. 2,382,103) uses spring clips to fasten the film to the ink fountain, with which the foil is clamped at the upper edge of the ink fountain. The films used here are relatively stiff and must therefore be adjusted to the shape of the ink fountain by folding them. After a certain period of time, the foil on its contact surface on the ink fountain roller has worn out and must be replaced. The circular section grinded in by the ink fountain roller must not be so large that the front film area would be cut off, because otherwise the ink metering device would become contaminated. The disadvantage of the known design is that the ink fountain must always be emptied to replace the film and that a new film is required in each case.

Aufgabe der Erfindung ist es, einen Farbkasten zu schaffen, bei dem die Benutzungsdauer der Folie verlängert wird und bei dem entsprechend weniger Entleerungen des Farbkastens erforderlich sind.The object of the invention is to provide an ink fountain in which the useful life of the film is extended and in which fewer empties of the ink fountain are required.

Die gestellte Aufgabe wird durch das Kennzeichen des Anspruchs 1 gelöst. Hiermit ist es möglich, die Folie gegenüber der Farbkastenwalze mehrfach zu verschieben und so deren Lebensdauer entsprechend zu verlängern. Nebenarbeiten, wie z. B. das Entleeren des Farbkastens, sind beim Verschieben der Folie nicht erforderlich.The object is achieved by the characterizing part of claim 1. This makes it possible to move the film several times over the ink fountain roller and thus to extend its service life accordingly. Side work, such as B. emptying the ink fountain are not required when moving the film Lich.

Vorteilhafte Ausgestaltungen der Erfindung sind durch die Merkmale der Unteransprüche gekennzeichnet. Es handelt sich jeweils um Lösungen, die das Verschieben der Folie auf einfache und kostengünstige Weise ermöglichen.Advantageous embodiments of the invention are characterized by the features of the subclaims. They are solutions that enable the film to be moved easily and inexpensively.

Ausführungsbeispiele der Erfindung sind in den Zeichnungen schematisch dargestellt.Embodiments of the invention are shown schematically in the drawings.

Es zeigt:

  • Fig. 1 einen Querschnitt durch einen Farbkasten,
  • Fig. 2 einen Teilquerschnitt durch einen Farbkasten,
  • Fig. 3 die Befestigung der elastischen Folie am oberen Rand des Farbkastens,
  • Fig. 4-7 eine elastische Folie mit verschiedenen untergelegten Stäben.
It shows:
  • 1 shows a cross section through an ink fountain,
  • 2 shows a partial cross section through an ink fountain,
  • 3 the fastening of the elastic film at the upper edge of the ink fountain,
  • Fig. 4-7 an elastic film with various underlying bars.

Bei Offset- oder Hochdruckmaschinen ist in bekannter Weise dem Farbkasten 1 eine Farbkastenwalze 2 zugeordnet, zwischen denen in einem keilförmigen Raum die Farbe 3 eingefüllt ist. Diese wird in einem dünnen Farbfilm von der Farbkastenwalze 2 in bekannter Weise über eine Heberwalze den Farbwerkswalzen zugeführt (nicht dargestellt) und von hier wiederum auf den Plattenzylinder übertragen. Der dünne Farbfilm läßt sich über eine Farbdosiereinrichtung 4 den jeweiligen Erfordernissen anpassen (Fig. 1). Zur Reinigung des Farbkastens 1 und der Farbkastenwalze 2 ist dieser abschwenkbar ausgebildet.. Die Länge des Farbkastens 1 und der Walzen wird entsprechend dem zu bedruckenden Papierformat ausgelegt. In bekannter Weise sind der Farbkasten und die Walzen beiderseits in nicht dargestellten Druckwerksseitenwänden gelagert.In offset or high-pressure machines, the ink fountain 1 is assigned a ink fountain roller 2 in a known manner, between which the ink 3 is filled in a wedge-shaped space. This is fed in a thin ink film from the ink fountain roller 2 in a known manner via a lifting roller to the inking unit rollers (not shown) and from there again transferred to the plate cylinder. The thin color film can be adapted to the respective requirements via a color metering device 4 (FIG. 1). To clean the ink fountain 1 and the ink fountain roller 2, the latter is designed to be pivotable. The length of the ink fountain 1 and the rollers is designed according to the paper format to be printed. In a known manner, the ink fountain and the rollers are mounted on both sides in printing unit side walls, not shown.

Die Farbdosiereinrichtung 4 besteht aus zonenbreiten Stellelementen 5, die sich, dicht nebeneinander angeordnet, über die Breite des Farbkastens 1 erstrecken. Die Stellelemente 5 sind zylindrisch ausgebildet und in zonenweise unterteilten Druckleisten 6 gelagert. Hierzu weisen die Druckleisten 6 in ihrem vorderen Bereich Ausnehmungen 7 auf. Sowohl die Stellelemente 5 als auch die Druckleisten 6 sind von einer elastischen Folie 8 abgedeckt. Die Druckfedern 9, die jeder Druckleiste 6 zugeordnet sind, drücken die Stellelemente 5 an die elastische Folie 8 und somit an die Farbkastenwalze 2 an, wobei der gewünschte Farbspalt über die Stellschrauben 10 zonenweise einstellbar ist. Die elastische Folie 8 ist im oberen Bereich des Farbkastens 1 befestigt und reicht normalerweise beiderseits bis unter die Verschlußstücke 11, die den Farbraum seitlich abdichten und über die Schrauben 12 festgeklemmt sind.The ink metering device 4 consists of zone-wide control elements 5 which, arranged closely next to one another, extend across the width of the ink fountain 1. The adjusting elements 5 are cylindrical and are mounted in pressure bars 6 divided into zones. For this purpose, the pressure strips 6 have recesses 7 in their front area. Both the adjusting elements 5 and the pressure strips 6 are covered by an elastic film 8. The compression springs 9, which are assigned to each pressure bar 6, press the actuating elements 5 against the elastic film 8 and thus against the ink fountain roller 2, the desired ink gap being adjustable in zones by means of the adjusting screws 10. The elastic film 8 is fastened in the upper region of the ink fountain 1 and normally extends on both sides to below the closure pieces 11, which seal the ink space laterally and are clamped in place via the screws 12.

Am oberen Rand 13 des Farbkastens 1 ist die elastische Folie 8 leicht herausnehmbar an einer sich über die Länge des Farbkastens erstreckenden Spannspindel 14 eingehängt. Hierzu weist die Spannspindel 14 einen Längsschlitz 15 auf. Über die Schraube 16 und den Hebel 17 läßt sich die Spannspindel 14 verdrehen, wobei sich die Schrauben 16 an den seitlichen Haltern 18 abstützen. Das Lager 19 für die Spannspindel 14 ist über die Schrauben 20 am oberen Rand 13 des Farbkastens 1 befestigt. Beim Verdrehen der Spannspindel 14 wird die elastische Folie 8 tangential zur Farbkastenwalze 2 verschoben, so daß nach dem Verschieben ein neuer, nicht abgenutzter Teil der Folienoberfläche an der Farbkastenwalze 2 anliegt. Der Längsschlitz 15 zum Einhängen der Folie könnte dann die in Figur 1 und 2 strichpunktiert gezeichnete Stellung einnehmen. Beim Verschieben der Folie müssen die Schrauben 12 für die seitlichen Verschlußstücke 11 etwas gelöst und nach dem Verschiebevorgang wieder angezogen werden.At the upper edge 13 of the ink fountain 1, the elastic film 8 is easily removed from a tensioning spindle 14 which extends over the length of the ink fountain. For this purpose, the clamping spindle 14 has a longitudinal slot 15. The clamping spindle 14 can be rotated via the screw 16 and the lever 17, the screws 16 being supported on the lateral holders 18. The bearing 19 for the clamping spindle 14 is fastened to the upper edge 13 of the ink fountain 1 by means of the screws 20. When the tensioning spindle 14 is rotated, the elastic film 8 is displaced tangentially to the ink fountain roller 2, so that after the displacement, a new, not worn part of the film surface rests against the ink fountain roller 2. The longitudinal slot 15 for hanging the film could then assume the position shown in broken lines in FIGS. 1 and 2. When moving the film, the screws 12 for the side closure pieces 11 must be loosened somewhat and tightened again after the displacement process.

In Figur 3 ist eine Ausführung der Erfindung wiedergegeben, bei der die elastische Folie 8 im oberen Bereich des Farbkastens 1 an einer Leiste 21 eingehängt ist. Parallel zu dieser sind weitere Leisten 22 und 23 am Farbkasten befestigt, die sich über die Länge desselben erstrecken. Zum Verschieben der elastischen Folie 8 gegenüber der Farbkastenwalze 2 läßt sich diese z. B. in die Leiste 22 einhängen (strichpunktiert gezeichnet), so daß ein neuer, nicht abgenutzter Teil der Folienoberfläche an der Farbkastenwalze anliegt.FIG. 3 shows an embodiment of the invention in which the elastic film 8 is suspended from a bar 21 in the upper region of the ink fountain 1. Parallel to this, further strips 22 and 23 are attached to the ink fountain, which extend over the length of the same. To move the elastic film 8 relative to the ink fountain roller 2, this can, for. B. hang in the bar 22 (dash-dotted lines), so that a new, not worn part of the film surface rests on the ink fountain roller.

Figur 4 zeigt die in die Leiste 21 eingehängte elastische Folie 8 mit einem untergelegten Stab 24 mit rechteckigem Querschnitt, wobei die längere Kante des Rechtecks senkrecht zur Folie steht, so daß ein größerer Verschiebeweg erreicht wird. In Figur 5 ist der Stab umgelegt, wodurch ein kleinerer Verschiebeweg eingestellt ist. Für den Drucker ist es vorteilhaft, zunächst den kleineren Verschiebeweg durchzuführen.FIG. 4 shows the elastic film 8 suspended in the strip 21 with an underlying rod 24 with a rectangular cross section, the longer edge of the rectangle being perpendicular to the film, so that a larger displacement path is achieved. In Figure 5, the rod is folded, whereby a smaller displacement path is set. It is advantageous for the printer to first carry out the smaller displacement path.

Die gleiche Wirkung läßt sich dadurch erreichen, daß, wie in Figur 6 gezeigt, ein Rundstab 25 mit größerem Durchmesser unter die Folie geschoben ist. Figur 7 zeigt einen Rundstab 26 mit kleinerem Durchmesser, wodurch beliebige Verschiebewege für die Folie erreicht werden können. Alle Stäbe 24, 25, 26 reichen über die Länge des Farbkastens und können zum bequemeren Einschieben in der Mitte geteilt sein, so daß jeweils die halbe Stablänge von einer Farbkastenseite eingeschoben werden muß. Auch hierbei müssen die Schrauben 12 für die Verschlußstücke 11 etwas gelöst und nach dem Verschiebevorgang wieder angezogen werden. Anstelle der Ausführung gemäß Figur 1 und 2 ist es dem Drucker somit möglich, gemäß den Figuren 3 bis 7 durch Unterlegen oder Entfernen von Stäben mit verschiedenen Dicken die elastische Folie 8 tangential zur Farbkastenwalze 2 zu verschieben, so daß auch mit diesen vorteilhaften Ausgestaltungen die Aufgabe der Erfindung gelöst ist.The same effect can be achieved in that, as shown in Figure 6, a round rod 25 with a larger diameter is pushed under the film. Figure 7 shows a round rod 26 with a smaller diameter, whereby any displacement paths for the film can be achieved. All rods 24, 25, 26 extend over the length of the ink fountain and can be divided in the middle for more convenient insertion, so that half the rod length must be inserted from one ink fountain side. Here, too, the screws 12 for the locking pieces 11 have to be loosened somewhat and tightened again after the displacement process. Instead of the embodiment according to FIGS. 1 and 2, it is therefore possible for the printer to move the elastic film 8 tangentially to the ink fountain roller 2 according to FIGS the invention is solved.
