Abstract
Description
Die Erfindung betrifft eine Druckmaschine mit einem Maschinengestell und mindestens zwei beim Drucken zusammenwirkenden Zylindern, die in einem durch das Maschinengestell gebildeten Gerüst gelagert sind.The invention relates to a printing press with a machine frame and at least two cylinders interacting in printing, in one are stored by the machine frame formed scaffold.
In Druckmaschinen werden die beim Drucken zusammenwirkenden Zylinder üblicherweise an beiden Enden jeweils in einem Seitenteil des Maschinengestells gelagert. So sind beispielsweise bei einer Flexodruckmaschine um einen Gegendruckzylinder herum mehrere Druckwerke mit Druckzylindern angeordnet. Zum Erzielen qualitativ hochwertiger Druckergebnisse ist die genaue Einhaltung eines optimalen Abstandes zwischen dem Gegendruckzylinder und den einzelnen Druckzylindern der Druckwerke notwendig. Eine durch Temperaturschwankungen hervorgerufene Ausdehnung oder Kontraktion des Gegendruckzylinders würde aufgrund des großen Durchmessers des Gegendruckzylinders, der beispielsweise im Bereich von 2m bis 3,5m liegen kann, eine deutliche Beeinträchtigung des Druckbildes ergeben. Aus diesem Grunde wird üblicherweise der Gegendruckzylinder mit einer Flüssigkeitskühlung temperiert, so daß das Außenmaß mit der erforderlichen Genauigkeit eingehalten wird.In printing presses, the cylinders interacting in printing become usually at both ends in each case in a side part of the machine frame stored. For example, a flexographic printing machine is an impression cylinder arranged around several printing units with printing cylinders. To the Achieving high-quality printing results is the strict adherence to one optimal distance between the impression cylinder and the individual Printing cylinders of the printing units necessary. One by temperature fluctuations caused expansion or contraction of the impression cylinder due to the large diameter of the impression cylinder, for example in the range of 2m to 3.5m, a significant impairment of the printed image. For this reason, usually the impression cylinder tempered with a liquid cooling, so that the external dimension is maintained with the required accuracy.
Aus der europäischen Patentschrift EP 0 150 047 der Anmelderin ist das Problem bekannt, daß innerhalb einer kurzen Zeitspanne nach dem Anlauf der Druckmaschine aufgrund von Schwankungen der Temperatur des Maschinengestells trotz eines temperaturstabilisierten Gegendruckzylinders Aussetzer im Druck auftreten. Mit einem linearen thermischen Ausdehnungskoeffizienten für Gußeisen von ca. 9 x 10-6 K-1 ergibt sich bei einer Schwankung der Temperatur des Maschinengestells um 10°C eine Änderung des Abstandes zwischen Druckzylinder und Gegendruckzylinder um einen Betrag von etwa 90 µm bis 160 µm, je nach Durchmesser des Gegendruckzylinders.From the European patent EP 0 150 047 of the applicant, the problem is known that occur within a short period of time after the start of the printing press due to fluctuations in the temperature of the machine frame despite a temperature-stabilized counter pressure cylinder misfires in the print. With a linear coefficient of thermal expansion for cast iron of about 9 x 10 -6 K -1 results in a variation of the temperature of the machine frame by 10 ° C, a change in the distance between the impression cylinder and counter-pressure cylinder by an amount of about 90 microns to 160 microns, depending on the diameter of the impression cylinder.
Zur Lösung dieses Problems schlägt die EP 0 150 047 ein temperaturstabilisiertes Maschinengestell vor. Zu diesem Zweck kann das Druckmaschinengestell etwa mit Wasserkanälen für ein Temperiersystem ausgerüstet sein. Mit einer Temperiereinrichtung mit Flüssigkeitskühlung kann beispielsweise bei einer Schwankung der Umgebungstemperatur im Drucksaal zwischen 15°C und 35°C die Temperaturschwankung des Maschinengestells auf einen Wert von ±1°C oder ±0,5°C begrenzt werden, wodurch die benötigte Maßhaltigkeit des Abstandes zwischen den Zylindern gewährleistet ist.To solve this problem, EP 0 150 047 proposes a temperature-stabilized Machine frame before. For this purpose, the printing press frame be equipped with water channels for a tempering system. With a Tempering device with liquid cooling can, for example, in a Fluctuation of the ambient temperature in the pressroom between 15 ° C and 35 ° C the temperature variation of the machine frame to a value of ± 1 ° C or ± 0.5 ° C, thereby reducing the required dimensional accuracy of the distance is guaranteed between the cylinders.
Aufgabe der Erfindung ist es, eine Druckmaschine der eingangs genannten Art zu schaffen, bei der die für eine optimale Druckqualität notwendige Maßhaltigkeit des Maschinengestells auf einfachere Art und Weise erreicht wird.The object of the invention is a printing press of the type mentioned to create the dimensional accuracy necessary for optimum print quality the machine frame is achieved in a simpler manner.
Diese Aufgabe wird erfindungsgemäß bei einer Druckmaschine der eingangs genannten Art dadurch gelöst, daß das Gerüst aus einem Material besteht, das wenigstens in einer Richtung quer zu den Drehachsen der Zylinder einen linearen thermischen Ausdehnungskoeffizienten kleiner als 2 x 10-6 K-1 hat. Sind die Seitenteile des Maschinengestells überwiegend aus einem solchen Material aufgebaut, so sind die thermischen Ausdehnungskoeffizienten des Materials in den Richtungen quer zu den Drehachsen der Zylinder für die thermische Ausdehnung des Maschinengestells bestimmend. Dadurch sind deutlich größere Temperaturschwankungen, etwa um 4°C, zulässig als beispielsweise bei der Verwendung eines herkömmlichen gußeisernen Maschinengestells, so daß die Temperierung des Maschinengestells vereinfacht wird.This object is achieved in a printing machine of the type mentioned fact that the framework consists of a material which has a linear thermal expansion coefficient at least in one direction transverse to the axes of rotation of the cylinder is less than 2 x 10 -6 K -1 . If the side parts of the machine frame are predominantly made of such a material, the thermal expansion coefficients of the material in the directions transverse to the axes of rotation of the cylinders are decisive for the thermal expansion of the machine frame. As a result, significantly greater temperature fluctuations, for example by 4 ° C, allowed than, for example, when using a conventional cast-iron machine frame, so that the temperature control of the machine frame is simplified.
Auf ein inneres Temperiersystem des Maschinengestells kann ganz verzichtet werden, wenn die Umgebungstemperatur im Drucksaal hinreichend konstant gehalten wird. Je nach Anwendungsfall könnte bei größeren Temperaturschwankungen auch eine stärkere Maßabweichung des Abstandes hinnehmbar sein. In den genannten Fällen kann daher auf ein Temperiersystem mit Flüssigkeitsumlauf durch das Maschinengestell verzichtet werden.An internal tempering system of the machine frame can be completely dispensed with when the ambient temperature in the pressroom is sufficiently constant is held. Depending on the application, could be larger temperature fluctuations also a greater dimensional deviation of the distance be acceptable. In The said cases can therefore on a temperature control system with fluid circulation be dispensed with by the machine frame.
Bevorzugt wird jedoch ein Material verwendet, dessen linearer thermischer Ausdehnungskoeffizient in der jeweiligen genannten Richtung sogar kleiner als 1 x 10-6K-1 ist, besonders bevorzugt jedoch kleiner als 0,5 x 10-6K-1 ist. Je geringer der thermische Ausdehnungskoeffizient ist, desto geringer kann der Temperieraufwand ausfallen und desto höhere Temperaturschwankungen im Drucksaal sind zulässig, um eine hohe Druckqualität zu gewährleisten. Bei einem Wegfall der Flüssigkeitskühlung ergibt sich ein einfacherer Aufbau der Druckmaschine und darüber hinaus eine Energieeinsparung im Betrieb.However, preference is given to using a material whose linear thermal expansion coefficient in the particular direction mentioned is even less than 1.times.10.sup.-6 K.sup.- 1 , but is particularly preferably less than 0.5.times.10.sup.-6 K.sup.- 1 . The lower the coefficient of thermal expansion, the lower the tempering effort can be and the higher the temperature fluctuations in the pressroom are permissible to ensure a high print quality. In the absence of liquid cooling results in a simpler construction of the printing press and beyond an energy saving during operation.
Wenn im folgenden an weiteren Stellen ein bevorzugter Wertebereich kleiner als 2 x 10-6K-1 für lineare thermische Ausdehnungskoeffizienten genannt wird, so gilt auch hier, daß ein Wert kleiner als 1 x 10-6K-1 vorteilhafter ist, und ein Wert kleiner als 0.5 x 10-6K-1 besonders bevorzugt wird. Im allgemeinen ist ein Ausdehnungskoeffizient um so vorteilhafter, je näher er an Null liegt.If a preferred value range below 2 × 10 -6 K -1 for linear thermal expansion coefficients is mentioned below in other places, then it applies here too that a value smaller than 1 × 10 -6 K -1 is more advantageous, and a value smaller than 0.5 x 10 -6 K -1 is particularly preferred. In general, an expansion coefficient is the more advantageous the closer it is to zero.
Vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous embodiments of the invention will become apparent from the dependent claims.
In einer besonders bevorzugten Ausführungsform hat das Gerüst Seitenteile, die Fenster bildende Streben aus einem Material aufweisen, das wenigstens in Richtung der jeweiligen Strebe einen linearen thermischen Ausdehnungskoeffizienten kleiner als 2 x 10-6 K-1 hat. Ein Material mit richtungsabhängigem thermischen Ausdehnungskoeffizienten kann daher besonders vorteilhaft eingesetzt werden; beispielsweise können die Streben aus kohlefaserverstärktem Kunststoff hergestellt sein, bei dem die Fasern jeweils in Längsrichtung der Strebe orientiert sind und von einer Matrix aus Kunststoff umgeben sind. Der lineare thermische Ausdehnungskoeffizient kann dann in Richtung jeder Strebe nahezu Null sein.In a particularly preferred embodiment, the framework has side parts which have window-forming struts made of a material which, at least in the direction of the respective strut, has a linear thermal expansion coefficient of less than 2 × 10 -6 K -1 . A material with directional thermal expansion coefficient can therefore be used particularly advantageously; For example, the struts can be made of carbon fiber reinforced plastic, in which the fibers are each oriented in the longitudinal direction of the strut and are surrounded by a matrix of plastic. The coefficient of linear thermal expansion may then be nearly zero in the direction of each strut.
Da ein thermischer Ausdehnungskoeffizient einer solchermaßen aufgebauten Strebe in Richtung quer zu der Strebe wenig zur thermischen Ausdehnung des Maschinengestells beiträgt, ist für das Maschinengestell der thermische Ausdehnungskoeffizient des Materials in der jeweiligen Richtung der Strebe für die resultierende thermische Ausdehnung entlang einer gedachten Verbindungslinie zweier Zylinder bestimmend.Since a coefficient of thermal expansion of such a constructed Struts in the direction transverse to the strut little to the thermal expansion of the Machine frame contributes, is for the machine frame, the thermal expansion coefficient of the material in the respective direction of the strut for the resulting thermal expansion along an imaginary connecting line determining two cylinders.
Bevorzugt ist das Material des Gerüsts ein Verbundmaterial, insbesondere ein Faserverbundwerkstoff, wobei eine möglichst hohe Festigkeit vorteilhaft ist. Das Verbundmaterial ist bevorzugt kohlefaserhaltiges Material, besonders bevorzugt kohlefaserverstärkter Kunststoff. Dabei können die Kohlefasern eine wie oben beschriebene Orientierung aufweisen.The material of the framework is preferably a composite material, in particular a Fiber composite material, with the highest possible strength is advantageous. The Composite material is preferably carbon fiber-containing material, more preferably Carbon fiber reinforced plastic. The carbon fibers can be one as above have described orientation.
Das Gerüst ist bevorzugt aus einem Kohlefaser-Verbundmaterial, Kohlefasermatten enthaltend, hergestellt.The framework is preferably made of a carbon fiber composite material, carbon fiber mats containing, prepared.
Außer den obengenannten Materialien kann zur Herstellung des Gerüstes auch Polymerbeton oder Mineralguß verwendet werden. Dieser Werkstoff kann bei geeignetem Herstellungsverfahren die notwendigen mechanischen Eigenschaften aufweisen, insbesondere einen, unter Umständen richtungsabhängigen, thermischen Ausdehnungskoeffizienten, der geringer ist als der von Stahl. Es ergeben sich die gleichen Vorteile wie bei der Verwendung der oben genannten Materialien. Es versteht sich, daß weitere geeignete, andere Verbundmaterialien, insbesondere Faserverbundmaterialien, zur Herstellung des Gerüstes verwendet werden können.In addition to the above-mentioned materials can also for the preparation of the framework Polymer concrete or mineral casting can be used. This material may be suitable Manufacturing process the necessary mechanical properties have, in particular one, possibly direction-dependent, thermal Coefficient of expansion, which is lower than that of steel. It revealed the same advantages as when using the above materials. It is understood that other suitable, other composite materials, in particular Fiber composite materials, used for the preparation of the scaffold can.

Figur 1 zeigt eine Teilseitenansicht einer Flexodruckmaschine, Figur 2 zeigt einen
Schnitt längs der Linie II-II in Figur 1. Die Druckmaschine weist ein Gerüst
in Form eines Gestells 10 auf, das zwei Seitenteile 12 und 14 aufweist. In Figur
1 ist nur das Seitenteil 12 zu erkennen. Zwischen den Seitenteilen 12 und 14 ist
ein Gegendruckzylinder 16 gelagert, an dessen Umfang mehrere Farbwerke 18
angeordnet sind. Jedes Farbwerk 18 umfaßt einen Druckzylinder 20 und eine
Auftragwalze 22. Die Seitenteile 12 und 14 weisen jeweils Streben 24 auf, zwischen
denen mehrere Fenster 26 ausgebildet sind. Die Druckzylinder 20 und die
Auftragwalzen 22 sind in Schlitten 28 gelagert, die längs Führungsschienen 30
verfahrbar sind. Die Führungsschienen 30 sind jeweils unterhalb eines zugehörigen
Fensters 26 auf der Innenseite des Seitenteils 12 bzw. 14 angebracht. Der
Gegendruckzylinder 16 weist Achsstummel 32 auf, mit denen er in den Seitenteilen
12 bzw. 14 gelagert ist.Figure 1 shows a partial side view of a flexographic printing machine, Figure 2 shows a

in the form of a
Die Seitenteile 12 und 14 des Gestells 10 sind jeweils als Formteil aus kohlefaserverstärktem
Kunststoff (CFK) hergestellt, indem Kohlefasermatten lagenweise
in eine Form eingelegt und mit Kunststoff vergossen wurden. The
Vorteile der Verwendung von kohlefaserverstärkten Kunststoffen sind ihre niedrige Dichte, ihre hohe Festigkeit und Steifigkeit, ihr geringer thermischer Ausdehnungskoeffizient, der deutlich kleiner als 1 x 10-6K-1 und richtungsabhängig sogar annähernd Null ist, und ferner geringe Herstellungskosten.Advantages of the use of carbon fiber reinforced plastics are their low density, high strength and stiffness, their low thermal expansion coefficient, which is significantly smaller than 1 x 10 -6 K -1 and even approximately zero, and also low manufacturing costs.

Pfeilen den Orientierungen der Kohlefasern entsprechende Richtungen an waagerechten
und senkrechten Streben 24 angegeben, entlang derer der lineare
thermische Ausdehnungskoeffizient des kohlefaserverstärkten Materials annähernd
gleich Null ist. Mit einem strichpunktiertem Pfeil ist die Verbindungslinie
zwischen den Lagerungen des Gegendruckzylinders 16 und eines Druckzylinders

Aufgrund des Aufbaus des Seitenteils 12 mit Fenstern 26 und Streben 24 ergibt
sich in der dargestellten Verbindungsrichtung ein resultierender Ausdehnungskoeffizient,
der im wesentlichen den Ausdehnungskoeffizienten in den mit
durchgezogenen Pfeilen dargestellten Richtungen entspricht. Dadurch kann innerhalb
der Ebene des Seitenteils 12 insgesamt für jede Verbindungsrichtung
zweier Zylinder ein resultierender thermischer Ausdehnungskoeffizient kleiner
oder gleich 0,45 x 10-6 K-1 erreicht werden.Due to the structure of the
So ergibt sich bei einer angenommenen Temperaturschwankung der Umgebungstemperatur im Drucksaal im Bereich von 15°C bis 35°C eine Maßhaltigkeit des Maschinengestells, die der eines auf ±0.5°C temperierten Maschinengestells aus Gußeisen mit einem thermischen Ausdehnungskoeffizienten von 9 x 10-6 K-1 mindestens entspricht. Eine Flüssigkeitstemperierung kann daher entfallen.Thus, assuming a temperature fluctuation of the ambient temperature in the press room in the range of 15 ° C to 35 ° C, a dimensional stability of the machine frame, that of a tempered to ± 0.5 ° C machine frame made of cast iron with a thermal expansion coefficient of 9 x 10 -6 K - 1 at least equal. Liquid temperature control can therefore be omitted.
