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 set 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 eine Farbkastenfolie, die mit Federspangen am oberen Rand des Farbkastens festgeklemmt ist. 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 dadurch die Farbdosierung in den einzelnen Zonen beeinträchtigt wird, oder daß gar 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 version (US-PS 2 382 103) uses an ink fountain film, which is clamped with spring clips on 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 ground in by the ink fountain roller must not assume such an extent that the ink metering in the individual zones is adversely affected, or that even 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.

Aus der CH-PS 383 413 schließlich ist ein Feuchtwerk an Offsetdruckmaschinen bekannt, bei dem eine Textilbahn vorgesehen ist, deren Vorrat auf einer über der Rakel angeordneten Rolle gespeichert und deren verbrauchter, verschmutzter Teil auf einer im Rahmen unterhalb des Rakelkörpers angeordneten Rolle aufgewickelt ist. Dabei besteht aufgrund der Reibkraft des sich drehenden Rotationszylinders die Gefahr des unbeabsichtigten Abrollens des Textilbandes von der Vorratsrolle.Finally, from CH-PS 383 413 a dampening unit on offset printing machines is known, in which a textile web is provided, the supply of which is stored on a roll arranged above the doctor blade and the used, soiled part of which is wound on a roller arranged in the frame below the doctor body. Due to the frictional force of the rotating rotary cylinder, there is a risk of the textile tape unintentionally rolling off the supply roll.

Aufgabe der vorliegenden Erfindung schließlich ist es, eine Möglichkeit aufzuzeigen, wodurch die Nutzungsdauer einer in einem Farbkasten für Offset- oder Hochdruckmaschinen verwendeten und durch die direkte Anlage an der Farbkastenwalze verschleißenden elastischen Folie verlängert werden kann.Finally, it is an object of the present invention to show a possibility whereby the useful life of an elastic film used in an ink fountain for offset or high-pressure machines and which is worn by the direct contact with the ink fountain roller can be extended.

Die gestellte Aufgabe wird durch die Kennzeichen der Ansprüche 1 und 2 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 stated object is achieved by the features of claims 1 and 2. This makes it possible to move the film several times over the ink fountain roller and thus to extend its service life accordingly. Ancillary work, such as emptying the ink fountain is not necessary when moving the film.

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 schernatisch dargestellt.Embodiments of the invention are shown schematically in the drawings.

Es zeigt:

  • Fig. 1 einen Querschnitt durch einem Farbkasten,
  • Fig. 2 einen Teilquerschnitt durch einen Farbkasten,
  • Fig. 3 die Befestigung der elastischen Folie am oberen Rand des Farbkasstens,
  • Fig. 4-7 eine elastische Folie mit verschiedenen unterlegten Stäben.
It shows:
  • 1 shows a cross section through an ink fountain,
  • 2 shows a partial cross section through an ink fountain,
  • 3 the attachment of the elastic film at the top of the ink fountain,
  • Fig. 4-7 is 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 Farbodosiereinrichtung 4 besteht aus zonenbreiten Stellelementen5, 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 abgedecket. Die Druckfedern 9, die jeder Druckleiste 6 zugeordnet, sind, drüchen 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 color 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 control 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 adjusting 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 by means of 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 zu 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 turning the clamping spindle 14, the elastic film 8 is moved tangentially to the ink fountain roller 2, so that after moving a new, not worn part of the Film surface rests on 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 2q 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 2q 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 thereof. To move the elastic film 8 relative to the ink fountain roller 2, this can e.g. 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.

Figure 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 Figure 5 ist der Stab umgelegt, wodurch ein kleinerer Verschiebeweg eingestellt ist. Für den Drucker ist est vorteilahft, zunächst den kleineren Verschiebeweg durchzuführen.Figure 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 has been folded over, which means that 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 Farkkastenseite eingeschoben werden muß. Auch hierbei müssen die Schrauben 12 für die Verschlußstücke 11 etwas gelöst und nach dem Verschiebevorgang wieder angezogen werden. Anstelle der Ausführungen gemäß Figuren 1 bis 3 ist es dem Drucker somit möglich, gemäß den Figuren 4 bis 7 durch Verdrehen um die Längsachse oder durch Unterlegen oder Entfernen von Stäben verschiedener Form und Dicke 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 of the 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 each side of the fountain. 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 embodiments according to FIGS. 1 to 3, it is thus possible for the printer to move the elastic film 8 tangentially to the ink fountain roller 2 according to FIGS. 4 to 7 by rotating about the longitudinal axis or by placing or removing bars of different shape and thickness, so that The object of the invention is also achieved with these advantageous configurations.
