Description

Die Erfindung bezieht sich auf eine Vorrichtung zum An- und Abstellen der Farbauftragwalzen gemäss dem Oberbegriff des Anspruches 1.The invention relates to a device for starting and stopping the inking rollers according to the preamble of claim 1.

Eine bekannte Ausführung dieser Art (DE-A 1 949092) offenbart ein Farbwerk mit drei Farbauftragwalzen, mit einer Lagerung auf Hebeln, die an den Seitengestellen befestigt sind. Den Lagerhebeln sind jeweils Stellhebel zugeordnet, die untereinander in Wirkverbindung stehen. Zum An- und Abstellen der Walzen ist beiderseits auf dem Lager des Plattenzylinders eine Nockenscheibe vorgesehen, auf der eine Rolle, die an einem der Steuerhebel befestigt ist, abrollt. Durch gleichzeitiges Verdrehen der beiden Nokkenscheiben auf jeder Maschinenseite können die Farbauftragwalzen an- oder abgestellt werden. Um jedoch eine Anlage der Rolle an der Nockenscheibe bzw. der Steuerhebel aneinander zu gewährleisten, werden mehrere Zugfedern benötigt, die die auf beiden Maschinenseiten vorgesehenen Steuerhebel in Anlage bringen.A known embodiment of this type (DE-A 1 949092) discloses an inking unit with three inking rollers, with a bearing on levers which are attached to the side frames. The bearing levers are each assigned actuating levers that are operatively connected to one another. To turn the rollers on and off, a cam disk is provided on both sides on the bearing of the plate cylinder, on which a roller that is attached to one of the control levers rolls. The inking rollers can be switched on or off by simultaneously turning the two cam discs on each side of the machine. However, in order to ensure that the roller abuts against the cam disk or the control lever, several tension springs are required which bring the control lever provided on both machine sides into contact.

Der Nachteil der bekannten Ausführung ist im wesentlichen in der instabilen Lagerung der Farbauftragwalze zu sehen. Rollen diese in ihrer angestellten Position auf der Druckplatte ab, so können z. B. beim Durchgang des Zylinderkanals Schläge entstehen, die zu Schwingungen der Walzen bzw. der Walzenlagerungen führen, so dass beim Aufsetzen der einzelnen Farbauftragwalzen auf die Druckplatte eine Beeinträchtigung der Einfärbung derselben eintreten kann. Insbesondere bei schnellaufenden Maschinen kann dies zu Walzenstreifen führen, die die Herstellung von hochwertigen Druckarbeiten unmöglich machen.The disadvantage of the known design is essentially to be seen in the unstable mounting of the inking roller. Roll these in their employed position on the pressure plate, so z. B. in the passage of the cylinder channel blows occur which lead to vibrations of the rollers or the roller bearings, so that when the individual inking rollers are placed on the printing plate, an impairment of the inking thereof can occur. In the case of high-speed machines in particular, this can lead to roller strips which make it impossible to produce high-quality printing work.

Die US-A 3538849 zeigt ein Farbwerk mit vier Farbauftragwalzen, die an beiden Maschinenseitengestellen auf Lagerhebeln gelagert sind, die schwenkbar auf den Lagerungen der nächstliegenden Reibwalzen angeordnet sind und Laschen zum An- und Abstellen der Farbauftragwalzen aufweisen. An den Laschen sind jeweils Stäbe befestigt, die mit nicht dargestellten Federn oder Druckmittelzylindern zusammenwirken. Nachdem somit für jeden Lagerhebel ein eigenes Stellmittel vorgesehen ist, ist ein gleichmässiges Anstellen der Auftragwalzen bei dieser Ausführung nicht gewährleistet, so dass auch die Einfärbung der Druckform nicht optimal ist.The US-A 3538849 shows an inking unit with four inking rollers, which are mounted on both machine side frames on bearing levers, which are pivotally arranged on the bearings of the nearest friction rollers and have tabs for turning the inking rollers on and off. Bars are attached to the tabs, which cooperate with springs or pressure medium cylinders, not shown. Since a separate adjusting means is thus provided for each bearing lever, a uniform setting of the application rollers cannot be guaranteed in this embodiment, so that the inking of the printing form is also not optimal.

Ausgehend von diesem Stand der Technik ist es Aufgabe der Erfindung, eine Lagerung und An-und Abstellung der Farbauftragwalzen, insbesondere bei einem Vier-Auftragwalzen-Farbwerk, zu schaffen, die eine gleichmässige und optimale Einfärbung der Druckform gewährleistet.Starting from this prior art, it is an object of the invention to provide storage and activation and deactivation of the inking rollers, in particular in a four-roller inking unit, which ensures uniform and optimal inking of the printing form.

Die Aufgabe wird mit den kennzeichnenden Merkmalen des Anspruches 1 gelöst. Mit dieser Lösung wird eine schwingungsfreie An- und Abstellung der Farbauftragwalzen erreicht, die ein gleichmässiges Anstellen derselben bei vorteilhafter Kraftverteilung in den Stellmitteln gewährleistet und auch über eine Fernbedienung betätigbar ist. Die Weiterbildung gemäss Anspruch 2 ermöglicht eine starre Anlage der Lagerhebel der Farbauftragwalzen, insbesondere in der angestellten Stellung, so dass Schwingungen vermieden werden, und eine feinfühlige Einstellung auch während des Maschinenlaufes möglich ist. Mit Anspruch 3 wird das Abstellen der Farbauftragwalzen dahingehend verbessert, dass für weitere an diesen anliegenden Farbwerkswalzen keine separate Steuerung benötigt wird.The object is achieved with the characterizing features of claim 1. With this solution, a vibration-free turning on and turning off of the inking rollers is achieved, which ensures a uniform turning of the same with an advantageous force distribution in the actuating means and can also be operated via a remote control. The development according to claim 2 enables a rigid contact of the bearing levers of the inking rollers, in particular in the employed position, so that vibrations are avoided and a sensitive adjustment is also possible while the machine is running. With claim 3, the parking of the inking rollers is improved in such a way that no separate control is required for further inking unit rollers resting on them.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt. Es zeigt:

  • Fig. eine Seitenansicht eines Farbwerks,
  • Fig. 2 einen Teilquerschnitt.
An embodiment of the invention is shown schematically in the drawings. It shows:
  • 1 shows a side view of an inking unit,
  • Fig. 2 shows a partial cross section.

Das in der Zeichnung wiedergegebene Ausführungsbeispiel bezieht sich auf ein Offsetdruckwerk mit einem Plattenzylinder 1 und einem Gummizylinder 2 in der bekannten Ausführung. Zur Ausführung von hochwertigen Druckarbeiten sind dem Plattenzylinder vier Farbauftragwalzen 3,4,5,6 zugeordnet, die um zwei Reibwalzen 7, 8 schwenkbar gelagert sind. Die Reibwalzen 7, 8 werden von einem nicht dargestellten Farbwerksantrieb mit Maschinengeschwindigkeit angetrieben. In bekannter Weise werden die Reibwalzen 7, 8 über eine Vielzahl Farbwerkswalzen 9 von einer Farbdosiereinrichtung 10 mit einer bestimmten Farbmenge versorgt.The embodiment shown in the drawing relates to an offset printing unit with a plate cylinder 1 and a blanket cylinder 2 in the known embodiment. In order to carry out high-quality printing work, four inking rollers 3, 4, 5, 6 are assigned to the plate cylinder and are pivotably mounted about two distribution rollers 7, 8. The friction rollers 7, 8 are driven by an inking mechanism drive, not shown, at machine speed. In a known manner, the friction rollers 7, 8 are supplied with a certain amount of ink by a dye metering device 10 via a plurality of inking unit rollers 9.

Die Farbauftragwalzen 3-6 sind in Lagerhebeln 11-14 gelagert, die um die Lagerungen 15 der nächstliegenden Reibwalze 7, 8 schwenkbar angeordnet sind. Jeweils zwei Lagerhebel 11, 12 bzw. 13, 14, die an beiden Maschinenseitengestellen vorgesehen sind, werden über Laschen 16-19 mit je einem Steuerhebel 20, 21 verbunden. Die Laschen sind hierbei über Bolzen 22 an Nokken 23 befestigt, die jeweils an den Lagerhebeln 11-14 vorgesehen sind. Auch die Verbindung mit den Steuerhebeln 20, 21 erfolgt über Bolzen 24. Die Steuerhebel 20, 21 selbst sind über Stehbolzen 25 am Maschinenseitengestell 26 befestigt (Figur 2). Zwischen beiden Steuerhebeln 20, 21 ist ein Ausgleichsteg 27 vorgesehen, der über Stehbolzen 28 mit den der Lagerung der Steuerhebel an den Stehbolzen 25 gegenüberliegenden Enden verbunden ist. An diesem Ausgleichsteg 27 greift über einen Gelenkkörper 29 die Kolbenstange 30 eines Stellzylinders 31 an. Dieser wiederum ist über einen Lagerkörper 32 am Maschinenseitengestell 26 abgestützt.The inking rollers 3-6 are mounted in bearing levers 11-14, which are arranged pivotably about the bearings 15 of the closest distributor roller 7, 8. Two bearing levers 11, 12 and 13, 14, respectively, which are provided on both machine side frames, are each connected to a control lever 20, 21 via tabs 16-19. The tabs are fastened here via bolts 22 to cams 23, which are each provided on the bearing levers 11-14. The connection to the control levers 20, 21 also takes place via bolts 24. The control levers 20, 21 themselves are fastened to the machine side frame 26 by means of stud bolts 25 (FIG. 2). Between the two control levers 20, 21, a compensating web 27 is provided, which is connected via stud bolts 28 to the ends opposite the bearing of the control levers on the stud bolts 25. The piston rod 30 of an actuating cylinder 31 acts on this compensating web 27 via a joint body 29. This in turn is supported on the machine side frame 26 via a bearing body 32.

Durch Betätigen des Stellzylinders 31 wird zum Anstellen der Auftragwalzen 3-6 der Ausgleichsteg 27 nach unten gedrückt, so dass die beiden Steuerhebel 20, 21 kniehebelartig bewegt werden. Hierbei drücken diese über die Bolzen 24 und die Laschen 16-19 die Lagerhebel 11-14 nach unten, so dass die Auftragwalzen 3-6 mit dem Plattenzylinder 1 in Kontakt kommen. Die Anstellbewegung wird hierbei über exzentrische Anschläge 33 begrenzt, an die sich die Ausnehmungen 34 in den Lagerhebeln 11-14 anlegen. Durch Verdrehen der Anschläge 33 über nicht dargestellte Stellspindeln lässt sich somit die Anstellkraft der Auftragwalzen 3-B an die Druckplatte des Plattenzylinders 1 feinfühlig einstellen. Bei Beaufschlagung des Stellzylinders 31 in umgekehrter Richtung erfolgt der entgegengesetzte Bewegungsablauf der einzelnen Stellmittel, wobei auch in der abgestellten Position die Lagerhebel 11-14 mit ihren Ausnehmungen 34 an den Anschlägen 33 anliegen.By actuating the actuating cylinder 31, the compensating web 27 is pressed downwards to set the application rollers 3-6, so that the two control levers 20, 21 are moved in the manner of a toggle lever. Here, they press the bearing levers 11-14 downward via the bolts 24 and the brackets 16-19, so that the application rollers 3-6 come into contact with the plate cylinder 1. The positioning movement is limited here by eccentric stops 33, against which the recesses 34 in the bearing levers 11-14 bear. By turning the stops 33 via adjusting spindles, not shown, the adjustment can thus be made using the application rollers 3-B on the pressure plate of the plate cylinder 1 adjust sensitively. When the actuating cylinder 31 is acted on in the opposite direction, the opposite movement sequence of the individual actuating means takes place, the bearing levers 11-14 also resting with their recesses 34 on the stops 33 in the parked position.

In vorteilhafter Ausgestaltung der Erfindung ist die an den Farbauftragwalzen 4, 5 anliegende Farbwerkswalze 35 über Gleitstücke 36 verschiebbar gelagert, so dass sie der An- und Abstellbewegung der Farbauftragwalzen ohne eigene Stellmittel folgen kann.In an advantageous embodiment of the invention, the inking unit roller 35 abutting the inking rollers 4, 5 is slidably mounted via sliding pieces 36, so that it can follow the on and off movement of the inking rollers without their own adjusting means.

Wie aus Figur 2 ersichtlich ist der Gelenkkörper 29 über einen Zapfen 37 mit dem Ausgleichsteg 27 verbunden. Auch ist bei dieser Figur dargestellt, dass die Auftragwalzen 3-6 über Lager 38 in den Lagerhebeln 11 bis 14 vorzugsweise auswechselbar gelagert sind.As can be seen from FIG. 2, the joint body 29 is connected to the compensating web 27 via a pin 37. This figure also shows that the application rollers 3-6 are preferably interchangeably mounted via bearings 38 in the bearing levers 11 to 14.
