Abstract
Description
Die vorliegende Erfindung betrifft eine Farbversorgungsvorrichtung für eine Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The The present invention relates to a ink supply device for a printing press according to the generic term of claim 1.
Druckmaschinen, beispielsweise für den Offsetdruck, werden üblicherweise durch Anlagen mit Druckfarbe versorgt, die eine Farbpumpe und einen entsprechenden Pumpenantrieb umfassen. Gewöhnlich werden in diesem Zusammenhang Kolbenpumpen eingesetzt, deren Kolbenstange durch einen Hydraulik- oder Pneumatikzylinder angetrieben wird.Printing machines, for example The offset printing, usually supplied by systems with printing ink, a paint pump and a corresponding Pump drive include. Usually In this context, piston pumps are used whose piston rod is driven by a hydraulic or pneumatic cylinder.
Die
Mit zunehmender Arbeitsgeschwindigkeit und Leistungsfähigkeit moderner Druckmaschinen steigt auch deren Farbverbrauch und damit das Fördervolu men der Farbpumpe. Ferner kann es in Fällen, in denen die Entfernung der Farbgebinde von der Druckmaschine sehr groß ist, erforderlich sein, einen sehr hohen Förderdruck aufzubauen. Aus diesen Gründen besteht ein Bedarf an Zylinderantrieben, die in der Lage sind, eine sehr hohe Antriebskraft aufzuwenden.With increasing work speed and performance Modern printing machines also increase their color consumption and thus the funding volume the color pump. It can also be used in cases where the removal the color pack from the printing press is very large, a very much needed high delivery pressure build. For these reasons There is a need for cylinder drives that are capable of to spend very high upload.
Eine Möglichkeit zur Erreichung dieses Ziels besteht darin, den Antriebszylinder entsprechend zu skalieren, d.h. das Volumen seiner Zylinderkammer zu vergrößern. Dies bringt jedoch verschiedene Nachteile mit sich. Die äußeren Abmessungen des Antriebszylinders werden unverhältnismäßig vergrössert. Ferner ergeben sich Probleme bezüglich der Versorgung mit dem Druckfluid, insbesondere bei Pneumatikzylindern, da ein entsprechend hoher Zuluft-Druck aufgebaut werden muß und der Luftverbrauch ansteigt. Zudem steigen die Kosten für die Konstruktion geeigneter einstufiger Zylinder, die sich an den üblichen Kolbenpumpen zur Farbförderung verwenden lassen.A possibility To achieve this goal is to drive the cylinder to scale accordingly, i. the volume of his cylinder chamber too enlarge. This brings with it several disadvantages. The outer dimensions of the drive cylinder are disproportionately increased. Furthermore arise Problems concerning the Supply of the pressurized fluid, in particular for pneumatic cylinders, because a correspondingly high supply air pressure must be established and the Air consumption increases. In addition, the cost of construction increases suitable single-stage cylinder, which conforms to the usual Use piston pumps for color promotion to let.
Aufgabe der vorliegenden Erfindung ist es daher, eine Farbversorgungsvorrichtung für Druckmaschinen der eingangs genannten Art zu schaffen, deren Antriebskraft sich zur Erhöhung des Fördervolumens sowie des Förderdrucks unter Vermeidung der vorstehend genannten konstruktiven Nachteile steigern lädt.task The present invention is therefore a color supply device for printing machines to create the type mentioned, the driving force itself to increase the volume of funding and the delivery pressure increase while avoiding the above-mentioned structural disadvantages invites.
Diese Aufgabe wird erfindungsgemäß durch eine Farbversorgungsvorrichtung mit den Merkmalen des Anspruchs 1 gelöst.These The object is achieved by a Color supply device with the features of claim 1 solved.
Der Zylinderantrieb der erfindungsgemäßen Farbversorgungsvorrichtung umfaßt mehrere voneinander getrennte Zylinderkammern, von denen jede Kammer einen mit dem hydraulischen oder pneumatischen Druck beaufschlagbaren Antriebskolben enthält, der an der Kolbenstange der Kolbenpumpe angebracht ist. Durch diese Konstruktion läßt sich eine höhere Antriebskraft erreichen, ohne daß ein übermäßiger Vordruck des Druckfluids aufgebaut werden muß oder der Fluidverbrauch übermäßig hoch ist. Zudem halten sich die äußeren Abmessungen eines derartigen Zylinderantriebs in vertretbaren Grenzen.Of the Cylinder drive of the ink supply device according to the invention comprises several separate cylinder chambers, each chamber one acted upon by the hydraulic or pneumatic pressure Contains drive piston, which is attached to the piston rod of the piston pump. Through this Construction can be a higher one Driving force without an excessive pre-pressure of the pressurized fluid must be built or the fluid consumption excessively high is. In addition, keep the outer dimensions such a cylinder drive within reasonable limits.
In einer bevorzugten Ausführungsform umfaßt der Zylinderantrieb mindestens einen Tandemzylinder.In a preferred embodiment comprises the cylinder drive at least one tandem cylinder.
In einer weiteren bevorzugten Ausführungsform umfaßt der Zylinderantrieb mindestens zwei parallel nebeneinander angeordnete Zylinderkammern, die jeweils einen Antriebskolben enthalten.In a further preferred embodiment comprises the cylinder drive at least two parallel juxtaposed Cylinder chambers, each containing a drive piston.
Im folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der beigefügten Zeichnung näher erläutert.in the The following will be a preferred embodiment of the invention based on the attached drawing explained in more detail.
