Description

Die vorliegende Erfindung betrifft eine Anlage zur Feuchtmittelaufbereitung und zur Temperierung einer Druckmaschine gemäß dem Oberbegriff des Anspruchs 1.The present invention relates to a system for dampening solution preparation and for tempering a printing press according to the preamble of claim 1.

Beim Offsetdruck wird auf die bildfreien Stellen der Druckplatte eine Beschichtung mit farbabstoJ3enden Eigenschaften aufgetragen, bevor die Druckfarbe aufgebracht wird. Während beim sogenannten Wasserlos-Offsetdruck eine Silikonschicht als farbabstoßende Schicht verwendet wird, werden beim Nass-Offsetdruck die bildfreien wasserannehmenden Stellen der Druckplattenoberfläche mit einem Feuchtmittel benetzt. Das Feuchtmittel zirkuliert in einem Feuchtmittel-Kreislauf zwischen dem Feuchtwerk der Druckmaschine und einem Feuchtmittelaufbereitungsgerät, in welchem es behandelt und anschließend wieder dem Feuchtwerk zugeführt wird.In offset printing, a coating with ink-repellent properties is applied to the non-image areas of the printing plate before the printing ink is applied. While in the so-called waterless offset printing a silicone layer is used as an ink-repellent layer, wet-offset printing, the non-image water-absorbing points of the printing plate surface are wetted with a dampening solution. The dampening solution circulates in a dampening solution circuit between the dampening unit of the printing machine and a dampening solution preparation device, in which it is treated and then returned to the dampening unit.

Da für die rheologischen Eigenschaften der Farbe die Temperatur von besonderer Bedeutung ist, kann es ferner notwendig sein, einzelne Baueinheiten der Druckmaschine, d.h., verschiedene Walzen, Walzengruppen oder ganze Farbwerke unterschiedlich zu temperieren. Hierzu dienen Temperiergeräte, die der Druckmaschine über einen entsprechenden Kreislauf Temperiermittel zuführen. Hierbei handelt es sich üblicherweise um einen Regelkreis, in welchem das rücklaufende Temperiermittel durch das Temperiergerät wieder auf die gewünschte Temperatur gebracht wird.Further, since the temperature is of particular importance for the rheological properties of the ink, it may be necessary to temper individual units of the printing machine, i.e., different rolls, groups of rolls or whole inking units differently. Serve this purpose tempering, which supply the press via a corresponding circuit tempering. This is usually a control loop in which the returning temperature control is brought by the temperature control unit back to the desired temperature.

Üblicherweise werden das Feuchtmittelaufbereitungsgerät und das Temperiergerät gemeinsam in das Gehäuse eines Peripheriegerätes integriert, so dass die gesamte Anlage platzsparend aufgestellt werden kann. Die bekannten Temperiergeräte sind relativ einfach konstruiert und umfassen einen gemeinsamen Temperiermittel-Kreislauf für alle Baueinheiten. Eine Einzelzonentemperierung, bei welcher verschiedene Teile der Druckmaschine auf unterschiedlichen Temperaturen gehalten werden, ist hierdurch nicht realisierbar.Typically, the dampening solution processing unit and the temperature control unit are integrated together in the housing of a peripheral device, so that the entire system can be installed to save space. The known temperature control devices are relatively simple in construction and comprise a common temperature control circuit for all units. A single-zone temperature control, in which different parts of the printing press are kept at different temperatures, can not be realized in this way.

Sollen einzelne Farbwerke oder Walzen individuell temperiert werden, muß der Druckmaschine bislang in separates Einzelzonentemperiergerät beigestellt werden, das für jede zu temperierende Baueinheit der Druckmaschine einen eigenen Temperiermittel-Kreislauf zur Verfügung stellt. Dies führt zu Platzproblemen und ist darüber hinaus unwirtschaftlich, da eine verhältnismäßig große Anzahl von Einzelgeräten zum Betrieb der Druckmaschine erforderlich ist. Der Installationsaufwand ist entsprechend hoch.If individual inking units or rollers are to be tempered individually, the printing press must hitherto be provided in a separate single-zone temperature control unit which provides its own temperature control circuit for each unit of the printing press to be tempered. This leads to space problems and is also uneconomical, since a relatively large number of individual devices for the operation of the printing press is required. The installation effort is correspondingly high.

Aufgabe der vorliegenden Erfindung ist es daher, eine Anlage der eingangs genannten Art zu schaffen, durch welche eine individuelle Temperierung verschiedener Baueinheiten einer Druckmaschine platzsparend und mit verhältnismäßig geringem apparativen und wirtschaftlichen Aufwand möglich wird.Object of the present invention is therefore to provide a system of the type mentioned, through which an individual temperature control of various units of a printing press space-saving and with relatively little equipment and economic effort is possible.

Diese Aufgabe wird erfindungsgemäß durch eine Anlage mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a system with the features of claim 1.

Erfindungsgemäß sind die verschieden zu temperierenden Baueinheiten der Druckmaschine durch voneinander getrennte Temperiermittel-Kreisläufe an ein Temperiermodul des Peripheriegerätes angeschlossen, welches dazu vorgesehen ist, die Temperaturen in den einzelnen Kreisläufen individuell zu regeln. Hierdurch wird eine Einzelzonentemperierung möglich, bei welcher beispielsweise verschiedene Farbwerke auf unterschiedlichen Temperaturen gehalten werden, da jedes Farbwerk mit dem Temperiermodul durch einen eigenen Temperiermittel-Kreislauf verbunden wird und auf eine vorbestimmte Temperatur gebracht werden kann. Weitere Temperiergeräte sind, nicht notwendig, so dass die Anlage platzsparend aufgestellt werden kann. Ferner ergeben sich Vorteile bezüglich der Konstruktion des Peripheriegerätes selbst, da beispielsweise ein einziges Kälteaggregat von mehreren Temperiermittel-Kreisläufen genutzt werden kann. Gegenüber dem Betrieb mit mehreren Geräten bietet die erfindungsgemäße Anlage daher wesentliche Vorteile.According to the invention, the components of the printing machine to be tempered differently are connected by separate temperature control circuits to a temperature control module of the peripheral device, which is provided for individually controlling the temperatures in the individual circuits. As a result, a single-zone temperature control is possible in which, for example, different inking units are kept at different temperatures, since each inking unit is connected to the tempering module by its own temperature control circuit and can be brought to a predetermined temperature. Other temperature control units are not necessary, so that the system can be installed to save space. Furthermore, there are advantages in terms of the construction of the peripheral device itself, since, for example, a single cooling unit can be used by several temperature control circuits. Compared to the operation with several devices, the system according to the invention therefore offers significant advantages.

In einer bevorzugten Ausführungsform der Erfindung handelt es sich bei den zu temperierenden Baueinheiten der Druckmaschine um verschiedene Farbwerke.In a preferred embodiment of the invention, the units to be tempered of the printing press are different inking units.

In einer weiteren bevorzugten Ausführungsform sind handelt es sich bei den Baueinheiten um verschiedene Walzen oder Walzengruppen der Druckmaschine.In a further preferred embodiment, the assemblies are different rolls or roll groups of the printing press.

Vorzugsweise umfasst das Peripheriegerät Funktionseinheiten, die vom Feuchtmittelaufbereitungsgerät und vom Temperiergerät gemeinsam genutzt werden.The peripheral device preferably comprises functional units which are shared by the dampening solution processing device and the temperature control device.

Bei diesen gemeinsam vom Feuchtmittelaufbereitungsgerät und vom Temperiergerät genutzten Funktionseinheiten handelt es sich bevorzugt um ein Kälteaggregat und/oder ein Energieversorgungsaggregat.These functional units used jointly by the dampening solution treatment device and the temperature control unit are preferably a refrigeration unit and / or a power supply unit.

Im folgenden wird ein bevorzugtes Ausführungsbeispiel der Erfindung anhand der beigefügten Zeichnung näher erläutert.In the following a preferred embodiment of the invention will be described with reference to the accompanying drawings.

Die einzige Figur zeigt schematisch den Aufbau einer Anlage, die ein Ausführungsbeispiel der vorliegenden Erfindung darstellt.The single figure shows schematically the construction of a plant, which represents an embodiment of the present invention.

Die im oberen Teil der Figur dargestellte und insgesamt mit der Bezugsziffer 10 bezeichnete Druckmaschine umfaßt vier Farbwerke 12,14,16,18, bei denen es sich um Kurzfarbwerke handelt. Jedes der Kurzfarbwerke 12,14,16,18 umfaßt eine Anzahl von Walzen, insbesondere jeweils eine Rasterwalze 20, deren Mantel in Oberflächenkontakt mit einer Auftragswalze 22 steht. Über weitere, nicht weiter bezeichnete Druckwalzen wird die Druckfarbe mittels der Rasterwalze 20 und der Auftragswalze 22 auf die zu bedruckende Oberfläche übertragen.The printing machine shown in the upper part of the figure and generally designated by the reference numeral 10 comprises four inking units 12,14,16,18, which are short inking units. Each of the short inking units 12, 14, 16, 18 comprises a number of rollers, in particular in each case an anilox roller 20, whose casing is in surface contact with an applicator roller 22. About more, not further designated pressure rollers, the ink is transferred by means of the anilox roller 20 and the applicator roller 22 to the surface to be printed.

Die Kurzfarbwerke 12,14,16,18 werden hier im sogenannten Nass-Offsetdruck betrieben, bei welchem die Oberflächen der Druckwalze, die keine Druckfarbe annehmen sollen, mit einem farbabstoßenden Feuchtmittel benetzt werden. Zu diesem Zweck ist jedem Kurzfarbwerk 12,14,16,18 ein Feuchtwerk 24 zugeordnet, welches das Feuchtmittel über eine Walzenanordnung zuführt. Das Feuchtmittel wird den einzelnen Feuchtwerken 24 der Druckmaschine 10 in einem geschlossenen Feuchtmittel-Kreislauf 26 zugeleitet, wie im folgenden noch näher beschrieben werden soll.The short inking units 12,14,16,18 are operated here in the so-called wet offset printing, in which the surfaces of the pressure roller, which should take no ink, are wetted with a ink-repellent dampening solution. For this purpose, a dampening unit 24 is assigned to each short inking unit 12,14,16,18, which supplies the dampening solution via a roller assembly. The dampening solution is fed to the individual dampening units 24 of the printing machine 10 in a closed dampening solution circuit 26, as will be described in more detail below.

Darüber hinaus können die Rasterwalzen 20 und die jeweiligen Auftragswalzen 22 temperiert werden, um die rheologischen Eigenschaften der Druckfarbe und damit die Qualität des Druckergebnisses zu steuern.In addition, the anilox rollers 20 and the respective applicator rollers 22 can be tempered to control the rheological properties of the ink and thus the quality of the printing result.

Zur Versorgung mit Feuchtmittel und zur Temperierung ist der Druckmaschine 10 ein Peripheriegerät 30 zugeordnet, das in der unteren Hälfte der Figur abgebildet ist. Bei diesem Peripheriegerät 30 handelt es sich im wesentlichen um einen Geräteschrank mit einem geschlossenen Gehäuse 32, das an seiner Frontseite Türen 34,36,38 aufweist, durch welche das Innere des Peripheriegeräts 30 zur Bedienung und für Wartungsarbeiten zugänglich ist. In das Peripheriegerät 30 sind auf nicht näher dargestellter Weise ein Feuchtmittelaufbereitungsgerät und ein Temperiergerät integriert.For supply with dampening solution and for temperature control of the printing press 10 is associated with a peripheral device 30, which is shown in the lower half of the figure. In this peripheral device 30 is essentially a cabinet with a closed housing 32 having on its front doors 34,36,38, through which the interior of the peripheral device 30 is accessible for operation and maintenance. In the peripheral device 30, a dampening solution processing device and a temperature control unit are integrated in a manner not shown.

Das Feuchtmittelaufbereitungsgerät ist über den Feuchtmittel-Kreislauf 26 mit den Feuchtwerken 24 der Druckmaschine 10 verbunden. Ein vom Peripheriegerät 30 ausgehender gemeinsamer Feuchtmittel-Vorlauf 40 verzweigt sich in einzelne Feuchtwerks-Zuleitungen 42, die jeweils zu einem Feuchtwerk 24 führen. Das benutzte Feuchtmittel wird von den Feuchtwerken 24 aus durch Feuchtwerks-Rückleitungen 44 abgeführt, die in einen gemeinsamen Feuchtmittel-Rücklauf 46 münden, der an das Peripheriegerät 30 angeschlossen ist und das Feuchtmittel wieder dem Feuchtmittelaufbereitungsgerät zurückführt, wo es für den erneuten Gebrauch aufbereitet wird und wieder in den Vorlauf 40 eingeleitet wird.The dampening solution preparation device is connected via the dampening solution circuit 26 with the dampening units 24 of the printing press 10. A common dampening solution feed 40 emanating from the peripheral device 30 branches into individual dampening unit feed lines 42, which each lead to a dampening unit 24. The dampening solution used is discharged from the dampening units 24 through dampening return lines 44, which open into a common dampening solution return 46, which is connected to the peripheral device 30 and the dampening solution back to the dampening solution processing unit, where it is prepared for reuse and is again introduced into the flow 40.

Sofern die Erfindung auf Geräte mit einer Feuchtmittelverteilung über einen Ejektorblock am Gerät angewendet werden soll, findet eine Verzweigung durch den Ejektorblock statt. Der Anwendung der Erfindung steht damit nichts im Wege.If the invention is to be applied to devices with a dampening solution distribution via an ejector block on the device, a branching takes place through the Ejektorblock. The application of the invention is thus nothing in the way.

In ähnlicher Weise werden die Auftragswalzen 22 der Kurzfarbwerke 12,14,16,18 durch einen gemeinsamen Temperiermittel-Kreislauf 48 mit Temperiermittel versorgt und auf diese Weise auf einer vorbestimmten Temperatur gehalten. Der Temperiermittel-Kreislauf 48 der Auftragswalzen 22 umfaßt einen Temperiermittel-Vorlauf 50, der vom Temperiergerät des Peripheriegerätes 30 ausgeht und sich in einzelne Temperiermittel-Zuleitungen 52 verzweigt, die zu den jeweiligen Auftragswalzen 22 führen.Similarly, the applicator rollers 22 of the short inking units 12,14,16,18 are supplied by a common temperature control circuit 48 with temperature control and kept in this way at a predetermined temperature. The temperature control circuit 48 of the applicator rollers 22 comprises a temperature control flow line 50, which starts from the temperature control unit of the peripheral device 30 and branches into individual temperature control supply lines 52, which lead to the respective applicator rollers 22.

Nach der Temperierung der Auftragswalzen 22 wird das Temperiermittel über Temperiermittel-Rückleitungen 54 abgeführt, die in einen gemeinsamen Temperiermittel-Rücklauf 56 münden, welcher zum Temperiergerät des Peripheriegerätes 30 zurückführt. Das Temperiergerät bringt das Temperiermittel wieder auf die gewünschte Temperatur, so dass es zur erneuten Zuleitung zu den Auftragswalzen 22 zur Verfügung steht.After the tempering of the applicator rollers 22, the temperature control is removed via Temperiermittel return lines 54, which open into a common Temperiermittel return 56, which leads back to the temperature of the peripheral device 30. The tempering brings the temperature control to the desired temperature, so that it is available for re-feeding to the applicator rollers 22.

Insbesondere kann das Temperiergerät eine Regelung umfassen, die unter Messung einer Ist-Temperatur, vorteilhafterweise im Bereich der Auftragswalzen 22, das Temperiermittel wieder auf die gewünschte Soll-Temperatur bringt. Mit Hilfe des Temperiermittel-Kreislaufs 48 lassen sich alle dargestellten Auftragswalzen 22 auf ein gemeinsames Temperaturniveau bringen.In particular, the temperature control device may include a control, which, while measuring an actual temperature, advantageously in the area of the application rollers 22, brings the temperature control means back to the desired desired temperature. With the aid of the temperature control circuit 48, all the applicator rollers 22 shown can be brought to a common temperature level.

Die Rasterwalzen 20 werden ebenfalls temperiert, jedoch abweichend von den Auftragswalzen 22 nicht über einen gemeinsamen Temperiermittel-Kreislauf 48, sondern es wird jede einzelne Rasterwalze 20 über einen individuellen Temperiermittel-Kreislauf 58,60,62,64 versorgt. Jeder einzelne der Temperiermittel-Kreisläufe 58,60,62,64 der Rasterwalzen 20 umfaßt einen Temperiermittel-Vorlauf 66, der vom Temperiergerät des Peripheriegerätes 30 ausgeht und zu der zu temperierenden Rasterwalze 20 führt, sowie einen Rücklauf 68, der das Temperiermittel nach dem Temperiervorgang wieder von der Rasterwalze 20 zum Temperiergerät zurückleitet. Das Temperiergerät ist dazu vorgesehen, das Temperiermittel jedes Temperiermittel-Kreislaufs 58,60,62;64 der Rasterwalzen 20 individuell anhand eines gemessenen IstWertes auf einen Soll-Wert zu regeln, so dass es möglich ist, bei Bedarf verschiedene Rasterwalzen 20 unterschiedlich zu temperieren.The anilox rollers 20 are also tempered, but not deviating from the applicator rollers 22 via a common Temperiermittel circuit 48, but it is supplied to each individual screen roller 20 via an individual temperature control circuit 58,60,62,64. Each of the temperature control circuits 58,60,62,64 of the anilox rollers 20 comprises a tempering agent supply line 66, which starts from the temperature of the peripheral device 30 and leads to the anilox roller 20 to be tempered, and a return 68, the temperature control after the tempering back from the anilox roller 20 to the temperature control device. The tempering device is provided to regulate the temperature control of each temperature control circuit 58,60,62; 64 of the anilox rollers 20 individually based on a measured actual value to a desired value, so that it is possible to temper different anilox rollers 20 different if necessary.

Wenngleich die Temperaturregelung also für jeden der Temperiermittel-Kreisläufe 48,58,60,62,64 separat vorgenommen werden kann, ist es möglich, innerhalb des Peripheriegerätes 30 beispielsweise ein gemeinsames Kälteaggregat für die Wassertemperierung zu nutzen. Ferner können dieses Aggregat sowie weitere Funktionseinheiten des Peripheriegerätes 30 gegebenenfalls mit dem Feuchtmittelaufbereitungsgerät geteilt werden, wie etwa Steuereinheiten, ein Energieversorgungsaggregat und dergleichen mehr. Auf diese Weise ist ein kostengünstiger Aufbau möglich. Durch die Integration der benötigten Geräte in ein einziges Peripheriegerät 30, das der Druckmaschine 10 beizustellen ist, sind der Platzbedarf und der Installationsaufwand gering.Although the temperature control can therefore be carried out separately for each of the temperature control agent circuits 48, 58, 60, 62, 64, it is possible to use within the peripheral device 30, for example, a common cooling unit for water temperature control. Further, this unit as well as other functional units of the peripheral device 30 may optionally be shared with the dampening solution processor, such as control units, a power supply unit, and the like. In this way, a cost-effective design is possible. By integrating the required devices in a single peripheral device 30, which is to provide the printing press 10, the space requirements and installation costs are low.

Mit Hilfe der voneinander getrennten Temperiermittel-Kreisläufe ist es möglich, nicht nur einzelne Walzen der Druckmaschine, sondern auch größere Baueinheiten individuell zu temperieren, so dass eine Einzelzonentemperierung der Druckmaschine 10 möglich ist. Diese Baueinheiten können Gruppen von Walzen oder auch gesamte Farbwerke umfassen.With the help of the separate temperature control circuits, it is possible not only individual rolls of the printing press, but also larger units to temper individually, so that a single-zone temperature control of the printing press 10 is possible.
