Abstract

The present invention relates to a method and a device for supplying pasty printing ink to printing machines. The purpose of this invention is to provide a method and a device for supplying ink according to an improved dosage while minimising cleaning operations. To this end, the quantity of printing ink is divided into a minimal ink quantity (4) and into a quantity of ink to be used (8). The minimal ink quantity (4) is stored in the ink tank (1), while the quantity of ink to be used (8) is directly applied onto the ductor roller (2).

Description

Verfahren und Einrichtung zur FarbzufuhrMethod and device for ink supply
Die Erfindung betrifft ein Verfahren und eine Einrichtung zur Farbzufuhr von pastösen Druckfarben an Druckmaschinen.The invention relates to a method and a device for the ink supply of pasty printing inks on printing presses.
Es sind Farbzuführungen an Druckmaschinen bekannt (DE-PS 30 30 774), die einen Farbkasten, eine Duktorwalze und eine Mehrzahl von längs der Duktorwalze aufeinanderfolgenden, einen veränderlichen Farbspalt bildenden Farbdosierelementen an der Farbkastenunterseite enthalten. Die pastöse Druckfarbe wird dabei in den durch Farbkastenunterseite einschließlich Farbdosierelementen und Duktorwalze gebildeten, offenen, keilförmigen Farbvorratsraum eingefüllt.Ink feeds on printing presses are known (DE-PS 30 30 774), which contain an ink fountain, a duct roller and a plurality of ink metering elements on the underside of the fountain which follow one another along the duct roller and form a variable ink gap. The pasty printing ink is poured into the open, wedge-shaped ink supply space formed by the underside of the ink fountain including ink metering elements and a doctor roller.
Nachteilig ist bei dieser Farbzuführung, daß der Farbvorratsraum sehr groß ist und sich deshalb Schwierigkeiten beim Farbwechsel bzw. beim Reinigen ergeben. Des weiteren ist die Dosierung der Farbzonenmenge nur über die Farbdosierelemente möglich.The disadvantage of this ink supply is that the ink supply space is very large and therefore difficulties arise when changing colors or when cleaning. Furthermore, the dosing of the amount of ink zones is only possible via the ink dosing elements.
Es sind auch Farbzuführeinrichtungen bekannt (DE 43 39 939 C2), bei denen der keilförmigeThere are also ink supply devices known (DE 43 39 939 C2) in which the wedge-shaped
Farbvorratsraum verkleinert und in geschlossener Bauart ausgeführt worden ist.Color storage space has been reduced and carried out in a closed design.
Die Farbzufuhr zu dem verkleinerten und geschlossenen Farbvorratsraum erfolgt unterThe ink supply to the reduced and closed ink supply room takes place under
Druck mittels Farbkartuschen.Printing with color cartridges.
Auch hier sind die Schwierigkeiten beim Reinigen und bei der Dosierung nicht beseitigt.The difficulties with cleaning and dosing have not been eliminated here either.
Aufgabe der Erfindung ist die Schaffung eines Verfahrens und einer Einπchtung zur Farbzufuhr mit verbesserter Dosierung und geringem Reinigungsaufwand.The object of the invention is to provide a method and a Einπchtung for ink supply with improved dosage and low cleaning effort.
Erfindungsgemäß wird die Aufgabe durch die Patentansprüche gelöst.According to the invention the object is solved by the claims.
