Description

Die Erfindung betrifft eine Bogenrotationsdruckmaschine mit Druckeinheiten für den Mehrfarbendruck und wenigstens einer Beschichtungseinheit nach dem Oberbegriff des Hauptanspruches.The invention relates to a sheet-fed rotary printing press with printing units for multicolor printing and at least one coating unit according to the preamble of the main claim.

Eine Bogenrotationsdruckmaschine dieser Art ist aus der EP 0 620 115 B1 bekannt. Zum Inline-Beschichten von Bedruckstoffen sind wenigstens zwei Lakkiereinheiten vorgesehen. Die in Bogenlaufrichtung vorgeordnete Lackiereinheit ist dabei als Flexodruckwerk mit einem eine Hochdruckform tragenden und mit dem bogenführenden Druckzylinder in Kontakt stehenden Formzylinder, einer mit dem Formzylinder in Kontakt stehenden gerasterten Auftragwalze zum Einfärben (Beschichten) und einem anstellbaren Kammerrakel, das mit einer Förderpumpe zur Beschichtungsflüssigkeitszufuhr und einer Saugpumpe zur Beschichtungsflüssigkeitsrückführung verbunden ist, ausgebildet.
Von Nachteil ist hierbei, daß bei erneuten Beschichtungsaufträgen die Druckform auf dem Formzylinder ausgetauscht werden muß und ggf. ist die ursprüngliche Rasterwalze gegen eine Rasterwalze mit abweichendem Schöpfvolumen auszutauschen. Der Wechsel der Druckform ist manuell als auch automatisiert aufwendig zu lösen und darüber hinaus entstehen durch die Umrüstung bedingte Stillstandszeiten an der Druckmaschine. A sheet-fed rotary printing machine of this type is known from EP 0 620 115 B1. At least two coating units are provided for inline coating of printing materials. The coating unit arranged upstream in the sheet running direction is a flexographic printing unit with a forme cylinder carrying a high-pressure form and in contact with the sheet-guiding printing cylinder, a rastered application roller for inking (coating) and an adjustable chamber doctor blade, which is equipped with a feed pump for coating liquid supply and a suction pump for coating liquid return is connected.
The disadvantage here is that the print form on the forme cylinder must be exchanged for renewed coating jobs and, if necessary, the original anilox roller must be exchanged for an anilox roller with a different scooping volume. The change of the printing form is time-consuming to do manually as well as automatically and the changeover also results in downtimes on the printing machine.

Aus der DE 195 03 951 A1 ist ein Verfahren sowie eine Vorrichtung für den Tiefdruck bekannt. Danach sind die Vertiefungen (Näpfchen) einer Tiefdruckrohform als Grundraster gleichmäßig mittels einer verflüssigbaren Substanz durch eine Auftragseinrichtung befüllbar, anschließend ist bildmäßig das Substanzmaterial mittels einer Bildpunkt-Übertragungseinrichtung aus den Vertiefungen abtragbar und die derart bildmäßig gerasterte Tiefdruckform ist mittels eines Einfärbesystems einfärbbar, um danach im Tiefdruck drucken zu können. Nach dem Druckvorgang ist die Tiefdruckform auf die Tiefdruckrohform regenerierbar und die Vertiefungen sind anschließend wieder befüllbar.DE 195 03 951 A1 describes a method and a device for gravure printing known. After that, the depressions (cups) of an intaglio printing blank are as Basic grid evenly using a liquefiable substance through a Application device can be filled, then the substance material is by means of an image a pixel transfer device can be removed from the wells and so rotogravure form, which is screened in an image, can be colored by means of a coloring system then be able to print in gravure. After the printing process is the gravure form can be regenerated to the gravure blank and the recesses are then again fillable.

Gemäß DE 39 06 648 A1 ist ein Auftragwerk für eine Druckmaschine bekannt, das im Offsetdruck, im Tiefdruck oder im Hochdruck einsetzbar ist. Als Auftragwerk weist dieses im Tiefdruck eine in einen Flüssigkeitsbehälter eintauchende Auftragwalze auf, welche die Flüssigkeit über einen gerasterten Formzylinder auf den Druckzylinder 1 aufträgt. Der gerasterte Formzylinder weist keinen Zylinderkanal zur zeitweiligen Aufnahme von Bogenhaltesystemen auf.According to DE 39 06 648 A1 an application unit for a printing press is known, which in Offset printing, in gravure printing or in letterpress printing can be used.

Der Erfindung liegt die Aufgabe zugrunde, eine Bogenrotationsdruckmaschine der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet, die mit ihren Druckeinheiten und insbesondere mit wenigstens einer Beschichtungseinheit, bei der ein Druckformwechsoi hinfällig ist, universeller einsetzbar ist und die Rüstzeiten spürbar reduziert.
Die Aufgabe wird durch die Ausbildungsmerkmale der Patentansprüche 1 und 9 gelöst. Weiterbildungen ergeben sich aus den abhängigen Ansprüchen.The invention has for its object to provide a sheet-fed rotary printing machine of the type described above, which avoids the disadvantages mentioned, which, with its printing units and in particular with at least one coating unit, in which a printing form change is no longer necessary, can be used more universally and the makeready times are noticeably reduced.
The object is achieved by the training features of claims 1 and 9. Further developments result from the dependent claims.

Die erfindungsgemäße Lösung gestattet es, neben der Erstellung eines Mehrfarbendruckes wenigstens eine Inline-Beschichtung auf einen Bedruckstoff aufzubringen. Dabei ist die Inline-Beschichtung neben dem bekannten Einfärben - durch Dosierung der Beschichtungsflüssigkeitsmenge - des Bedruckstoffes als bildmäßige (sujetbedingte) vorzugsweise Inline-Bebilderung mit einer Inline-Beschichtung durchführbar.
Die vorzugsweise mittels Leitstand gesteuerte Bogenrotationsdruckmaschine weist dazu neben den Druckeinheiten wenigstens eine Beschichtungseinheit auf, die zumindest aus einem Bogenführungszylinder, einem Formzylinder sowie einem Dosiersystem mit einer gerasterten Auftragwalze als Tiefdruckrohform oder dem Formzylinder selbst als Tiefdruckrohform gebildet ist. The solution according to the invention allows at least one inline coating to be applied to a printing material in addition to the creation of a multicolor print. In addition to the known inking - by metering the amount of coating liquid - of the printing material, the inline coating can be carried out as imagewise (subject-related), preferably inline imaging with an inline coating.
For this purpose, the sheet-fed rotary printing press, which is preferably controlled by means of a control station, has, in addition to the printing units, at least one coating unit which is formed at least from a sheet guide cylinder, a forme cylinder and a metering system with a rastered application roller as a gravure blank form or the form cylinder itself as a gravure blank form.

Weiterhin gestattet die erfindungsgemäße Lösung eine Inline-Beschichtung in der Beschichtungseinheit und eine Erzeugung der Tiefdruckform auf der Auftragwalze oder dem Formzylinder außerhalb der Bogenrotationsdruckmaschine in einer separaten Einrichtung.
Dabei ist eine derartige separate Einrichtung auch an oder auf einer Druckeinheit und/oder Beschichtungseinheit separat anordbar. Das Wechseln der Auftragwalze oder des Formzylinders zwischen der Beschichtungseinheit und der separaten Einrichtung zur Erzeugung der Tiefdruckform ist manuell oder bevorzugt mittels eines Handhabesystems durchführbar. Alternativ ist dieses Prinzip auf eine Druckeinheit für den Mehrfarbendruck übertragbar, wenn diese Druckeinheit einen Formzylinder als Tiefdruckform (direkter Tiefdruck) oder eine Auftragwalze als Tiefdruckform (indirekter Tiefdruck) aufweist. Die separate Einrichtung zur Erzeugung der Tiefdruckform ist somit auch an oder auf wenigstens einer Druckeinheit für den Mehrfarbendruck anordbar.Furthermore, the solution according to the invention permits inline coating in the coating unit and generation of the rotogravure form on the application roller or the forme cylinder outside the sheet-fed rotary printing press in a separate device.
Such a separate device can also be arranged separately on or on a printing unit and / or coating unit. The change of the application roller or the forme cylinder between the coating unit and the separate device for producing the gravure form can be carried out manually or preferably by means of a handling system. Alternatively, this principle can be transferred to a printing unit for multi-color printing if this printing unit has a form cylinder as a gravure form (direct gravure) or an application roller as a gravure form (indirect gravure). The separate device for producing the rotogravure form can thus also be arranged on or on at least one printing unit for multicolor printing.

Beispielsweise ist oberhalb der Beschichtungseinheit auf dieser die separate Einrichtung zur Erzeugung der Tiefdruckform anordbar. Der separaten Einrichtung ist als Handhabesystem beispielsweise ein Industrieroboter benachbart zugeordnet, welcher die Auftragwalze oder den Formzylinder aus den Halterungen der Beschichtungseinheit entnimmt und der separaten Einrichtung zur Erzeugung der Tiefdruckform zuführt bzw. aus der separaten Einrichtung in die jeweilige Halterung zurückführt.
In einer weiteren Ausbildung ist der separaten Einrichtung zur Erzeugung der Tiefdruckform weiterhin ein Magazin als Walzen/Zylinder-Speicher zugeordnet. Das Handhabesystem entnimmt dabei die Auftragwalze oder den Formzylinder wiederum aus den Halterungen und führt die Auftragwalze oder den Formzylinder dem Magazin zu bzw. aus dem Magazin zur jeweiligen Halterung zurück. Die Erzeugung der Tiefdruckform auf der Auftragwalze oder dem Formzylinder ist dabei im Magazin durch die separate Einrichtung erzielbar. For example, the separate device for producing the rotogravure form can be arranged on the coating unit above it. An industrial robot, for example, is assigned to the separate device as a handling system, which takes the applicator roller or the forme cylinder from the holders of the coating unit and feeds them to the separate device for producing the rotogravure form or returns them from the separate device to the respective holder.
In a further embodiment, the separate device for producing the rotogravure form is also assigned a magazine as a roller / cylinder store. The handling system in turn removes the applicator roller or the forme cylinder from the holders and guides the applicator roller or the forme cylinder to the magazine or back from the magazine to the respective holder. The generation of the gravure form on the applicator roller or the forme cylinder can be achieved in the magazine by the separate device.

Das Magazin ist in einfachster Form auch als Walzen/Zylinder-Halterung für die zeitweilige Aufbewahrung von Auftragwalze und/oder Formzylinder nutzbar. Darüberhinaus ist das Magazin auch für die Aufnahme mehrerer Auftragwalzen und/oder Formzylinder ausführbar. Die Belegung der Speicherplätze (für Walzen /Zylinder) im Magazin und/oder die Aktivierung des Handhabesystems sowie der separaten Einrichtung zur Erzeugung der Tiefdruckform ist bevorzugt von einem gekoppelten Leitstand aus steuerbar. Dabei stellt das Magazin auch eine Walzen/Zylinder-Ordnung her, wie sie an der separaten Einrichtung zur Erzeugung der Tiefdruckform sowie der Aufbewahrungsposition benötigt wird.
Handhabesystem, Magazin und separate Einrichtung sind nicht auf die Zuordnung zu einer Beschichtungseinheit beschränkt, vielmehr ist eine Anordnung dieser Baugruppen auch an oder auf, insbesondere oberhalb wenigstens einer Druckeinheit realisierbar.In its simplest form, the magazine can also be used as a roller / cylinder holder for the temporary storage of application roller and / or forme cylinder. In addition, the magazine can also be designed to hold several applicator rollers and / or form cylinders. The occupancy of the storage spaces (for rollers / cylinders) in the magazine and / or the activation of the handling system and the separate device for generating the rotogravure form can preferably be controlled from a coupled control station. The magazine also produces a roller / cylinder arrangement, as is required on the separate device for producing the gravure form and the storage position.
Handling system, magazine and separate device are not limited to the assignment to a coating unit, but an arrangement of these modules can also be realized on or on, in particular above at least one printing unit.

Als Dosiersystem eignen sich mehrere Ausbildungen. So ist in einer ersten Ausbildung eine Dosierwalze der gerasterten Auftragwalze (als Zweiwalzenwerk) zugeordnet und in den derart gebildeten Walzenspalt wird die Beschichtungsflüssigkeit zugeführt. In einer zweiten Ausbildung ist der gerasterten Auftragwalze ein Kammerrakel zugeordnet, welches mit einem Kreislaufsystem für die Beschichtungsflüssigkeit gekoppelt ist. Schließlich ist in einer dritten Ausbildung zumindest eine Schöpfwalze der gerasterten Auftragwalze zugeordnet. Aus einem Vorratsbehälter wird die Beschichtungsflüssigkeit geschöpft und zum Walzenspalt gefördert.Several training courses are suitable as dosing systems. This is the first training a metering roller assigned to the screened application roller (as a two-roll mill) and the coating liquid is in the nip thus formed fed. In a second embodiment, the screened application roller is a chambered doctor blade assigned, which with a circulation system for the coating liquid is coupled. After all, at least one is in a third training Bucket roller assigned to the screened application roller. From a storage container the coating liquid is scooped and conveyed to the nip.

Die gerasterte Auftragwalze selbst ist als eine Tiedruckrohform mit Vertiefungen (Näpfchen) und Stegen als Grundraster ausgebildet. Mit Bezug auf einen einfachgroßen Formzylinder der Beschichtungseinheit ist diese gerasterte Auftragwalze zumindest im gleichen Durchmesser oder größer ausgebildet. Vorzugsweise für partiell wiederkehrende Druckaufträge ist der Durchmesser der Auftragwalze einem geradzahligen Teil eines einfachgroßen Formzylinders entsprechend ausgebildet.
Der Formzylinder weist einen die Beschichtungsflüssigkeit aufnehmenden Überzug sowie bevorzugt einen Zylinderkanal auf. Im wesentlichen kongruent zum Zylinderkanal des Formzylinders weist die gerasterte Auftragwalze in einem Kreissegment des Teilumfangs eine eben gekrümmte Fläche im Walzenmantel auf, wobei dieser Teilumfang in zwei Ausbildungen ausführbar ist.The screened applicator roller itself is designed as a low-pressure raw form with depressions (cups) and webs as a basic screen. With respect to a single-sized forme cylinder of the coating unit, this rastered application roller is at least of the same diameter or larger. The diameter of the application roller is preferably designed for an even-numbered part of a single-size forme cylinder, preferably for partially recurring print jobs.
The forme cylinder has a coating which receives the coating liquid and preferably a cylinder channel. Essentially congruent to the cylinder channel of the forme cylinder, the rastered applicator roller has a flat curved surface in the roller shell in a circular segment of the partial circumference, this partial circumference being able to be implemented in two configurations.

In erster Ausbildung ist der auf Höhe der Oberkante der Stege liegende Teilumfang eine glatte Fläche (ohne Grundraster) und in zweiter Ausbildung ist das bereits beschriebene Grundrasters vorgesehen, welches zur Erzielung einer ebenen Fläche mit einem Material vollständig gefüllt ist.In the first training, the partial circumference lying at the level of the upper edge of the webs a smooth surface (without basic grid) and in second training that is already described basic grid provided, which to achieve a flat surface is completely filled with a material.

In einer Ausbildung ist der gerasterten Auftragwalze eine Antrageinrichtung zum Befüllen der Vertiefungen des Grundrasters mit einer verflüssigbaren Substanz, eine Abtrageinrichtung zum bildmäßigen (sujetbedingten) Entfernen der Substanz aus der Vertiefungen des Grundrasters und eine Regenerationseinrichtung zum Regenerieren der Tiefdruckform zurück auf das Grundraster (Tiefdruckrohform) zugeordnet. In dieser Ausbildung ist die Beschichtungseinheit für die Inline-Bebilderung sowie Inline-Beschichtung einsetzbar.In an apprenticeship, the screened application roller is an application device for Filling the recesses of the basic grid with a liquefiable substance, a removal device for imagewise (subject-related) removal of the substance from the wells of the basic grid and a regeneration device for Regenerate the rotogravure form back to the basic grid (rotogravure raw form) assigned. In this training, the coating unit for inline imaging and inline coating can be used.

In einer weiteren Ausbildung ist die gerasterte Auftragwalze außerhalb der Beschichtungseinheit mittels o.g. Regenerationseinrichtung, Antrageinrichtung und Abtrageinrichtung entsprechend des Beschichtungssujets bebilderbar und anschließend in die Beschichtungseinheit, dem Formzylinder und Dosiersystem zugeordnet, einsetzbar.In a further embodiment, the rastered application roller is outside the coating unit by means of the above Regeneration facility, application facility and Removal device can be imaged according to the coating subject and then assigned to the coating unit, the forme cylinder and dosing system, used.

Ein erster Vorteil der Erfindung ist darin begründet, daß das Wechseln der Druckformen auf dem Formzylinder bei der Inline-Bebilderung der gerasterten Auftragwalze und anschließender Inline-Beschichtung in der Beschichtungseinheit hinfällig ist. Damit lassen sich Rüstzeiten verkürzen und die Beschichtungseinheit ist universeller einsetzbar. Erfolgt die Bebilderung der gerasterten Auftragwalze außerhalb der Beschichtungseinheit ist insbesondere von Vorteil, daß die Tiefdruckform, ohne Stillstandszeiten der Druckmaschine, erzeugbar ist und anschließend lediglich ein Austausch bzw. Einsetzen der Auftragwalze in den Lagerstellen der Beschichtungseinheit erforderlich ist.A first advantage of the invention is based on the fact that changing the printing forms on the forme cylinder during inline imaging of the rasterized Applicator roller and subsequent inline coating in the coating unit is obsolete. This can shorten set-up times and the coating unit is more universal. Is the image of the rastered application roller outside the coating unit, it is particularly advantageous that the gravure form, can be generated without downtimes of the printing press, and then only an exchange or insertion of the application roller in the bearings the coating unit is required.

Weiterere Vorteile der Erfindung sind darin begründet, daß bei bildmäßiger Beschichtung die Beschichtungsflüssigkeit formatbezogen auf den Bedruckstoff auftragbar ist. Damit ist das Aufbauen von überschüssiger Beschichtungsflüssigkeit an Walzen oder Zylindern vermeidbar. Die gewünschte Bebilderung ist jederzeit regenerierbar. Falls doch die Beschichtungsflüssigkeit aufbaut, z.B. bei schnell aushärtenden Beschichtungsflüssigkeiten, ist diese automatisch entfembar. Ein mögliches Aushärten der Beschichtungsflüssigkeit auf der gerasterten Auftragwalze ist somit durch Freilegen des Grundrasters vermeidbar.
Durch die bildmäßige Beschichtung sind darüber hinaus innerhalb eines Druck-bzw. Beschichtungssujets unterschiedliche Glanzeffekte bzw. Glänzungsgrade erzielbar, z.B. indem partiell unterschiedliche Schichtdicken erzeugt werden. Weiterhin sind beispielsweise gleichmäßige, gestufte und/oder unterschiedliche Beschichtungsdicken sowie Teilbeschichtungen in Umfangs- als auch Querrichtung erzielbar.Further advantages of the invention are based on the fact that, in the case of imagewise coating, the coating liquid can be applied to the printing material in a format-related manner. The build-up of excess coating liquid on rollers or cylinders can thus be avoided. The desired illustration can be regenerated at any time. If the coating liquid builds up, for example in the case of rapidly curing coating liquids, it can be removed automatically. A possible hardening of the coating liquid on the screened application roller can thus be avoided by exposing the basic screen.
Due to the pictorial coating, moreover, within a printing or. Coating subjects can achieve different gloss effects or degrees of gloss, for example by partially producing different layer thicknesses. Furthermore, for example, uniform, stepped and / or different coating thicknesses and partial coatings in the circumferential and transverse directions can be achieved.

Durch den Einsatz von Regenerationseinrichtung, Antrageinrichtung und Abtrageinrichtung sind die Vertiefungen der gerasterten Auftragwalze zumindest periodisch auf das Grundraster (Tiefdruckrohform) zurückführbar.Through the use of regeneration equipment, application equipment and removal equipment are the depressions of the screened application roller at least periodically traceable to the basic grid (gravure blank).

Die Beschichtungseinheit gestattet die Verarbeitung von unterschiedlichen Beschichtungsflüssigkeiten, wie beispielsweise Flexodruckfarbe, pigmenthaltiger Effektdruckfarbe und Dispersionslack, wobei insbesondere Beschichtungsflüssigkeiten auf wässriger Basis Anwendung finden.
Die Beschichtungseinheit ist im direkten oder indirekten Tiefdruck betreibbar. Die Druckeinheiten für den Mehrfarbendruck sind als Offsetdruckwerke und/oder direkte oder indirekte Tiefdruckwerke, vorzugweise Flexodruckwerke, ausgebildet.The coating unit permits the processing of different coating liquids, such as flexographic printing ink, pigment-containing effect printing ink and dispersion varnish, in particular coating liquids on an aqueous basis being used.
The coating unit can be operated in direct or indirect gravure printing. The printing units for multi-color printing are designed as offset printing units and / or direct or indirect gravure printing units, preferably flexographic printing units.

    • eine Antrageinrichtung 19 zum Befüllen der Vertiefungen der Tiefdruckrohform (Grundraster) der Auftragwalze 13 mit einer verflüssigbaren Substanz 25,
    • eine Abtrageinrichtung 20, z.B. ein Laser 27 , zum bildmäßigen Entfernen dieser Substanz 25 aus den Vertiefungen und somit Schaffung der Tiefdruckform, sowie
    • eine Regenerationseinrichtung 18 zum Regenerieren (Löschen der verbliebenen Substanz 25) der Auftragwalze 13 auf die Tiefdruckrohform (Grundraster) mittels Reinigungsfluid 29,
      umfangsseitig zugeordnet.
    In a first embodiment, within at least one coating unit 2, 3 of the application roller 13:
    • an application device 19 for filling the depressions of the gravure blank form (basic grid) of the application roller 13 with a liquefiable substance 25,
    • a removal device 20, for example a laser 27, for imagewise removal of this substance 25 from the depressions and thus creation of the gravure form, and
    • a regeneration device 18 for regenerating (deleting the remaining substance 25) of the application roller 13 onto the gravure blank form (basic grid) by means of cleaning fluid 29,
      assigned to the circumference.

    In zweiter Ausbildung sind außerhalb der Beschichtungseinheit 2 und/oder 3 die Antrageinrichtung 19, die Abtrageinrichtung 20 sowie die Regenerationseinrichtung 18 angeordnet. Die gerasterte Auftragwalze 13 ist dabei außerhalb der jeweiligen Beschichtungseinheit 2,3 bebilderbar und ist anschließend als Tiefdruckform in die Halterungen (Walzenlagerungen) der entsprechenden Beschichtungseinheit 2, 3 einsetzbar.
    Alternativ ist die außerhalb bebilderte Tiefdruckform der gerasterten Auftragwalze 13 als Hülse ausgebildet und ist in Sleeve-Technik auf einen Walzengrundkörper axial aufziehbar bzw. abziehbar. Hierbei ist die Auftragwalze 13 mit Tiefdruckform als Hülse wiederum in die Walzenlagerungen der jeweiligen Beschichtungseinheit 2, 3 einsetzbar oder die Tiefdruckform als Hülse ist innerhalb der Beschichtungseinheit 2,3 auf einen fixierten Walzengrundkörper auf- bzw. abziehbar.    In a second embodiment, the application device 19, the removal device 20 and the regeneration device 18 are arranged outside the coating unit 2 and / or 3. The rastered application roller 13 can be imaged outside the respective coating unit 2, 3 and can then be used as a gravure form in the holders (roller bearings) of the corresponding coating unit 2, 3.
    Alternatively, the gravure form of the screened application roller 13, which is illustrated on the outside, is designed as a sleeve and can be axially pulled up or pulled off on a roller base body using sleeve technology. In this case, the applicator roller 13 with the intaglio printing plate as a sleeve can in turn be inserted into the roller bearings of the respective coating unit 2, 3, or the intaglio printing plate as the sleeve can be pulled up and down on a fixed roller base body within the coating unit 2, 3.

    Alternativ ist auf der Auftragwalze 13 eine bereits bebilderte oder noch zu bebildernde Tiefdruckform als Platte aufspannbar. Dabei ist ein Spannkanal kongruent zum Zylinderkanal 22 des Formzylinders 12 angeordnet und ist abdeckbar, derart, daß die Abdeckung analog zum Kreissegment 23 eine eben gekrümmte Fläche im Walzenmantel ist.

    Die Fig. 3 bis 5 zeigen verschiedene Ausführungen der Dosiersysteme 14, die einzeln den Beschichtungseinheiten 2 und/oder 3 wahlweise zuzuordnen sind. Darüberhinaus eignen sich diese Dosiersysteme 14 auch für den Einsatz in Druckwerken 1 für den Mehrfarbendruck, welche als Flexodruckwerke ausgebildet sind.     Alternatively, an already imaged or still to be imaged intaglio printing plate can be clamped on the application roller 13. Here, a clamping channel is congruent to the cylinder channel 22 of the forme cylinder 12 and can be covered in such a way that the cover is a flat curved surface in the roller shell analogous to the circular segment 23. In one development, the tensioning channel can be filled with the liquefiable substance 25. The substance 25 can be removed again by means of the regeneration device 18.

    Gemäß Fig. 3 ist das Kammerrakel 15 in Kontakt mit der gerasterten Auftragwalze 13 dargestellt. In das Gehäuseinnere des Kammerrakels 15 wird die Beschichtungsflüssigkeit in einem Kreislaufsystem mit geringfügigem Überdruck zu- bzw. abgeführt. Der Formzylinder 12 trägt als kompressiblen Überzug 21 eine elastische vollflächige, vorzugsweise flexible Hochdruckform (ohne Relief). In Drehrichtung 24 der Auftragwalze 13 sind nach der Kontaktstelle mit dem Formzylinder 12 die Regenerationseinrichtung 18, die Antrageinrichtung 19 und die Abtrageinrichtung 20 der Auftragwalze 13 zugeordnet.3, the doctor blade 15 is in contact with the screened application roller 13 shown. The coating liquid is in the interior of the chamber doctor blade 15 in a circulatory system with slight overpressure dissipated. The form cylinder 12 has an elastic cover as a compressible cover 21 full-surface, preferably flexible high-pressure form (without relief). In direction of rotation 24 the application roller 13 are the regeneration device after the contact point with the forme cylinder 12 18, the application device 19 and the removal device 20 assigned to the application roller 13.

    Gemäß Fig.4 ist das Dosiersystem 14 mit der gerasterten Auftragwalze 13 und einer nach dem Quetschwalzenprinzip arbeitenden Dosierwalze 16 gebildet. Das so gebildete Zweiwalzenwerk erhält von oben in den Walzenspalt (Auftragwalze 13 / Dosierwalze 16) die Beschichtungsflüssigkeit zugeführt, wobei stirnseitig überschüssige Beschichtungsflüssigkeit abführbar ist. Der Formzylinder 12 trägt dabei als kompressiblen Überzug 21 eine Flachdruckform, z.B. ein Gummituch, mit noch näher beschriebenen Eigenschaften. Die Anordnung der Regenerationseinrichtung 18, der Antrageinrichtung 19 und der Abtrageinrichtung 20 ist analog zu Fig. 3. Alternativ ist der Dosierwalze 16 auch ein Behälter 31 zuordbar, so daß die Dosierwalze 16 die Funktion einer Schöpfwalze übernimmt. Die Zuführung von Beschichtungsflüssigkeit von oben in den Walzenspalt ist somit hinfällig.According to Figure 4, the metering system 14 with the screened application roller 13 and a metering roller 16 working according to the squeeze roller principle. The the two-roll mill thus formed receives from above into the roll nip (applicator roll 13 / Metering roller 16) fed the coating liquid, with excess on the end face Coating liquid can be removed. The forme cylinder 12 carries as a compressible coating 21 a planographic printing form, e.g. a rubber blanket with still properties described in more detail. The arrangement of the regeneration device 18, the application device 19 and the removal device 20 is analogous to FIG. 3. Alternatively, the metering roller 16 can also be assigned a container 31, so that the metering roller 16 takes over the function of a scoop roller. The supply of coating liquid from above into the nip is therefore no longer necessary.

    Schließlich ist gemäß Fig. 5 ein Dosiersystem 14 dargestellt, welches eine in einen Behälter 31 mit Beschichtungsflüssigkeit eintauchende Schöpfwalze 17 in Kontakt mit der gerasterten Auftragwalze 13 zeigt.

The forme cylinder 12 carries as Coating 21 a printing film.

    Die verwendeten Überzüge 21 sind nicht auf das entsprechende Dosiersystem 14 beschränkt. The coatings 21 used are not based on the corresponding metering system 14 limited.

    Um eine mögliche Rückspaltung von Druckfarbe aus vorgeordneten Druckeinheiten 1 auf den Überzug 21 zu vermeiden bzw. zu reduzieren weist der Überzug 21 die o.g. Druckfarbe abstoßende, jedoch die Beschichtungsflüssigkeit annehmende Eigenschaften auf. Alternativ ist dem Formzylinder 12 mit seinem Überzug 21 eine Waschvorrichtung zum Reinigen des Überzuges 21 zugeordnet. Bevorzugt ist diese Waschvorrichtung eine traversierende Sprühwaschvorrichtung mit Absaugung, die vorzugsweise während des Beschichtungsprozesses den Überzug 21 von rückgespalteter Druckfarbe freihält oder reinigt oder zumindest benetzt.A possible splitting of printing ink from upstream printing units 1 to avoid or reduce the coating 21, the coating 21 has the above-mentioned Ink repellent, but accepting the coating liquid Properties on. Alternatively, the forme cylinder 12 with its coating 21 is one Washer for cleaning the cover 21 assigned. Is preferred this washing device is a traversing spray washing device with suction, preferably coating 21 during the coating process keeps the ink free from back splitting or cleans or at least wets it.

    Innerhalb der Bogenrotationsdruckmaschine ist wenigstens eine Beschichtungseinheit 2 oder 3 mit den Druckeinheiten 1 für den Mehrfarbendruck in Funktionsverbindung. Diese Druckeinheiten 1 sind dabei als Offsetdruckwerke und/oder Flexodruckwerke ausgebildet.
    Daraus ergeben sich folgende Anordnungen:

    • wenigstens eine Beschichtungseinheit 2,3 ist zwischen den Druckeinheiten 1 für den Mehrfarbendruck (Offsetdruckwerke und/oder Flexodruckwerke) anordbar,
    • wenigstens eine Beschichtungseinheit 2,3 ist vor den Druckeinheiten 1 für den Mehrfarbendruck (Offsetdruckwerke und/oder Flexodruckwerke) anordbar, und
    • wenigstens eine Beschichtungseinheit 2,3 ist nach den Druckeinheiten 1 für den Mehrfarbendruck (Offsetdruckwerke und/oder Flexodruckwerke) anordbar.
    Within the sheet-fed rotary printing press, at least one coating unit 2 or 3 is functionally connected to the printing units 1 for multi-color printing. These printing units 1 are designed as offset printing units and / or flexographic printing units.
    This results in the following arrangements:
    • at least one coating unit 2, 3 can be arranged between the printing units 1 for multi-color printing (offset printing units and / or flexographic printing units),
    • at least one coating unit 2, 3 can be arranged in front of the printing units 1 for multi-color printing (offset printing units and / or flexographic printing units), and
    • at least one coating unit 2, 3 can be arranged after the printing units 1 for multi-color printing (offset printing units and / or flexographic printing units).

    In einer nicht gezeigten weiteren Ausbildung ist in das Dosiersystem 14 der Formzylinder 12 als Tiefdruckrohform mit einem Vertiefungen aufweisenden Grundraster integriert. Das Dosiersystem 14 benötigt hierbei keine Auftragwalze 13, sondern ist wahlweise als Kammerrakel 15, Dosierwalze 16 oder Schöpfwalze 17 anstellbar an den Formzylinder 12 ausgebildet.

    Die Wirkungsweise ist im wesentlichen wie folgt: Nach den, vor den oder auch zwischen den Druckeinheiten 1 für den Mehrfarbendruck sind die Beschichtungseinheiten 2,3 einzeln oder mehrfach anordbar. Dies schließt auch Druckeinheiten 1 als Widerdruckwerke und/oder Druckeinheiten 1 mit in Bogenförderrichtung vorgeordneten Wendeeinrichtungen ein. So ist beispielsweise in einer in Bogenförderrichtung dem ersten Druckwerk 1 vorgeordneten Beschichtungseinheit 2 (oder 3) eine vollflächige oder partielle Deckbeschichtung des Bedruckstoffes erzielbar. Bei einer zwischen den Druckwerken 1 angeordneten Beschichtungseinrichtung 2 (oder 3) ist beispielsweise eine vollflächige Deckbeschichtung einer Bedruckstoffseite realisierbar und anschließend ist eine Wendung des Bogens mit anschließender Zuführung in weitere Druckwerke 1 durchführbar. Bei den Druckwerken 1 nachgeordneten Beschichtungseinheiten 2,3 ist beispielsweise in der ersten Beschichtungseinheit 2 eine vollflächige oder partielle Lackierung (mit Dispersionslack auf wäßriger Basis) auf den Bedruckstoff aufbringbar und anschließend ist in der zweiten Beschichtungseinheit 3 eine partielle - in den Dispersionslack schwimmend eingelagerte - weitere Lackierung, z.B. mittels Goldlack, aufbringbar.The mode of operation is essentially as follows: after, before or are between the printing units 1 for multicolor printing Coating units 2, 3 can be arranged individually or several times. This also includes Printing units 1 as counter printing units and / or printing units 1 with in Sheet conveying upstream turning devices. So is for example, in a first printing unit 1 in the sheet conveying direction upstream coating unit 2 (or 3) a full or partial Top coating of the substrate can be achieved. With one between the Printing units 1 arranged coating device 2 (or 3) for example a full-surface top coating of a printing material side realizable and then there is a turn of the bow with subsequent Feeding into further printing units 1 can be carried out. With the printing units 1 subordinate coating units 2, 3 is in the first, for example Coating unit 2 a full-surface or partial coating (with dispersion coating on an aqueous basis) can be applied to the printing material and then is in the second coating unit 3 a partial - in the dispersion paint floating - further painting, e.g. by means of gold lacquer, can be applied.

    Zum Beschichten des Bedruckstoffes erhält das jeweils eingesetzte Dosiersystem 14 die Beschichtungsflüssigkeit zugeführt. Die in der jeweiligen Beschichtungseinheit 2, 3 einzusetzende, gerasterte Auftragwalze 13 wird innerhalb oder außerhalb bebildert. Dabei stellt die - vorzugsweise als Keramikwalze - gerasterte Auftragswalze 13 die Tiefdruckrohform als Grundraster dar.
    Die Bebilderung erfolgt in Drehrichtung 24 der Auftragwalze 13 gem. Fig. 6 in nachstehenden Schritten. An der Antrageinrichtung 19 werden die Vertiefungen der Tiefdruckrohform mit der verflüssigbaren Substanz 25 befüllt. In Drehrichtung 24 weist die Antrageinrichtung 19 Abstreifelemente 26 auf, die die überschüssige Substanz 25 an der Oberfläche der Stege abrakeln. Die Substanz 25 härtet aus. Die Abtrageinrichtung 20 beinhaltet u.a. den Laser 27, der - abhängig vom Beschichtungssujet - aus der Substanz 25 bildmäßig einen Abtrag 30 freilegt, so daß nun die eigentliche Tiefdruckform vorliegt. Diese Tiefdruckform auf der gerasterten Auftragwalze 13 wird anschließend vom Dosiersystem 14 mit Beschichtungsflüssigkeit befüllt, die Beschichtungsflüssigkeit wird mengenmäßig und dem Sujet entsprechend auf den Überzug 21 des Formzylinders 12 übertragen und im Druckspalt auf den auf dem Druckzylinder 10 geführten Bedruckstoff übergeben. Wird die Tiefdruckform nicht mehr benötigt oder ist eine Regenerierung dieser erforderlich, so wird durch die Regenerationseinrichtung 18 ein Reinigungsfluid 29 auf die Substanz 25 aufgebracht, welches die Substanz 25 aus den Vertiefungen durch Absaugen (einschließlich des Reinigungsfluides 29) innerhalb eines Gehäuses 28 entfernt. Die gerasterte Auftragwalze 13 liegt wieder als Tiefdruckrohform vor und kann erneut bebildert werden.     To coat the printing material, the metering system 14 used in each case receives the coating liquid. The screened application roller 13 to be used in the respective coating unit 2, 3 is imaged inside or outside. In this case, the application roller 13, which is rasterized, preferably as a ceramic roller, represents the gravure blank as the basic raster.
    The imaging takes place in the direction of rotation 24 of the application roller 13 according to. Fig. 6 in steps below. At the application device 19, the depressions of the rotogravure blank are filled with the liquefiable substance 25. In the direction of rotation 24, the application device 19 has wiping elements 26 which wipe off the excess substance 25 on the surface of the webs. The substance 25 hardens. The removal device 20 includes, inter alia, the laser 27, which - depending on the coating subject - exposes a removal 30 from the substance 25, so that the actual gravure form is now available. This gravure printing form on the screened application roller 13 is then filled with coating liquid by the metering system 14, the coating liquid is transferred in quantity and in accordance with the subject to the coating 21 of the forme cylinder 12 and transferred in the printing nip to the printing material guided on the printing cylinder 10. If the rotogravure form is no longer required or if it needs to be regenerated, the regeneration device 18 applies a cleaning fluid 29 to the substance 25, which removes the substance 25 from the recesses by suction (including the cleaning fluid 29) within a housing 28. The screened application roller 13 is again in the form of an intaglio printing form and can be imaged again.
