Description

Die Erfindung betrifft eine Vorrichtung zur Nachbehandlung Inline lackierter Druckbogen innerhalb der Druckmaschine.The invention relates to a device for aftertreatment Inline varnished printed sheets inside the press.

Zur Lackierung von Druckbogen in Bogenoffsetdruckmaschinen sind derzeit umstellbare Feucht-Lackierwerke und separate Lackierdruckwerke (Lacktürme) eingesetzt. Diese Einrichtungen ermöglichen Glanzlackierungen von genannten Druckbogen und Teilflächen im Inline-Prozeß, sowohl mit einer von beiden Einrichtungen, als auch mit beiden Einrichtungen hintereinander. For coating printed sheets in sheetfed offset printing machines are currently convertible wet coating units and separate Coating printing units (coating towers) used. These facilities enable gloss varnishing of the printed sheets mentioned and partial areas in the inline process, both with a from both facilities, as well as with both facilities behind each other.  

Um ein Ablegen im Stapel zu vermeiden sind diesen Lackiereinrichtungen entsprechende Trockenstrecken nachgeordnet. Einer der wesentlichsten Gründe für die Lackierung von Druckprodukten ist neben dem Oberflächenschutz und der Scheuerfestigkeit die Erzeugung eines glänzenden Aussehens. Der Grad des Glanzes ist dabei von den Lackeigenschaften, dem Bedruckstoff und der Lackschichtdicke abhängig.In order to avoid placing them in the stack, these are painting facilities corresponding drying sections arranged downstream. One of the main reasons for painting Print products is in addition to the surface protection and Abrasion resistance creating a shiny appearance. The degree of gloss depends on the paint properties, depending on the substrate and the coating thickness.

Trotz des mehrmaligen Lackierens in der Druckmaschine sind bei der Inline Lackierung dem Grad des Glanzes Grenzen gesetzt, die meist in der Oberflächenrauheit des lackierten Druckproduktes begründet sind.Despite repeated painting in the printing press the inline painting limits the degree of gloss, mostly in the surface roughness of the painted Print product are justified.

Besonders bei hohen Qualitätsansprüchen ist die Inline Lackiertechnologie aus diesem Grund nicht anwendbar, sondern es macht sich ein separater Arbeitsgang in Form von Lackieren oder Glätten außerhalb der Druckmaschine erforderlich.The Inline is particularly useful when there are high quality requirements Painting technology is not applicable for this reason, but it makes a separate operation in the form of Painting or smoothing required outside of the press.

Die Aufgabe der Erfindung besteht deshalb darin, eine Vorrichtung zur Nachbehandlung Inline lackierter Druckbogen zu schaffen, womit eine glanzverbessernde Glättung innerhalb der Druckmaschine erreicht wird.The object of the invention is therefore a device for after-treatment inline coated printed sheets create, with which a gloss-improving smoothing within the printing press is reached.

Gelöst wird die Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1. The task is solved by the characteristic features of claim 1.  

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispieles näher erläutert werden.The invention is intended to be explained below using an exemplary embodiment are explained in more detail.

In der zugehörigen Zeichnung zeigtIn the accompanying drawing shows

Fig. 1 eine schematische Darstellung einer Druckmaschine mit separater Lackiereinrichtung und Kalandrierwerk Fig. 1 is a schematic representation of a printing press with a separate coating device and calender

Fig. 2 eine Darstellung gemäß Fig. 1 mit zum Kalandrierwerk umgerüsteter Lackiereinrichtung. FIG. 2 shows an illustration according to FIG. 1 with the coating device converted to the calendering unit.

Die Fig. 1 zeigt die letzten drei Aggregate einer Mehrfarben-Bogenrotationsdruckmaschine, bestehend aus umstellbarem Druck-Lackierwerk 1, separatem Lackierwerk 2 und Kalandrierwerk 3. Diese einzelnen Aggregate sind über die Druckzylinder 4 und die Übergabetrommeln 5 untereinander, bis hin zur Auslage, verbunden. Fig. 1 shows the last three units of a multicolor sheet-fed rotary printing machine, consisting of umstellbarem pressure coating unit 1, a separate coating unit 2 and Kalandrierwerk. 3 These individual units are interconnected via the pressure cylinders 4 and the transfer drums 5 up to the delivery.

Das schematische dargestellte Farbwerk 6 sowie das umstellbare Feucht-Lackierwerk 7 stehen über dem Plattenzylinder 8 und dem Gummizylinder 9 mit dem Druckzylinder 4 des Druck- Lackierwerks 1 in Körperkontakt.The schematically illustrated inking unit 6 and the convertible wet coating unit 7 are in body contact with the printing cylinder 4 of the printing coating unit 1 via the plate cylinder 8 and the rubber cylinder 9 .

Dem Druckzylinder 4 des Lackierwerkes 2 ist ein Lackformzylinder 10 nachgeordnet an dem eine Lackauftragwalze 11, eine Schöpfwalze 12 und eine Dosierwalze 13 anstellbar ist.The printing cylinder 4 of the coating unit 2 is followed by a coating forme cylinder 10 on which a coating roller 11 , a scoop roller 12 and a metering roller 13 can be set.

Im auslaufenden Walzenspalt zwischen Druckzylinder 4 und Gummizylinder 9 sowie Lackformzylinder 10 sind jeweils allgemein bekannte Trockner 14 angestellt.Well-known dryers 14 are employed in each case in the running nip between the pressure cylinder 4 and the blanket cylinder 9 and the coating form cylinder 10 .

Den beiden Aggregaten 1 und 2 ist ein Kalandrierwerk 3 bestehend aus Druckzylinder 4 und Kalandrierzylinder 15 nachgeordnet. A calendering unit 3 consisting of pressure cylinder 4 and calendering cylinder 15 is arranged downstream of the two units 1 and 2 .

Auf den Kalandrierzylinder 15 ist eine Glättplatte 16 mit sehr glatter Oberfläche, z. B. Chrom aufgespannt. Zusätzlich ist die Glättplatte 16 mit einer lackabweisenden Schicht belegt, um das Risiko des Lackaufreißens möglichst gering zu halten, auch bei unvollständig angetrocknetem Lack.On the calendering cylinder 15 is a smoothing plate 16 with a very smooth surface, for. B. chrome. In addition, the smoothing plate 16 is coated with a lacquer-repellent layer in order to keep the risk of lacquer tearing open as low as possible, even when the lacquer is not completely dry.

Vor der Einlaufzone Druckzylinder 4 - Kalandrierzylinder 15 sind zusätzlich Sprühdüsen 17 angeordnet, um die Glättplatte 16 gegebenenfalls mit Trennmittel besprühen zu können, welches einen oleophilen Charakter hat und sich rückstandslos verflüchtigt. Mit dieser Maßnahme soll ein Ankleben der Lackschicht an der Glättplatte 16 vermieden werden.In addition, spray nozzles 17 are arranged in front of the inlet zone of the pressure cylinder 4 - calendering cylinder 15 in order to be able to spray the smoothing plate 16, if necessary, with a release agent which has an oleophilic character and volatilizes without residue. This measure is intended to prevent the lacquer layer from sticking to the smoothing plate 16 .

Mit diesem zusätzlichen Kalandrierwerk 3 wird höchsten Qualitätsansprüchen in Bezug auf die veredelte Oberfläche des Druckproduktes innerhalb eines Maschinendurchlaufes entsprochen, da in diesem Aggregat durch Druckpressung die Lackschicht geglättet und somit die Glanzwirkung erreicht wird.This additional calendering unit 3 meets the highest quality requirements with regard to the finished surface of the printed product within one machine run, since the coating layer is smoothed in this unit by pressure pressing and the gloss effect is thus achieved.

Ableitend von dieser Maschinenkonfiguration mit doppelter Lackiermöglichkeit, d. h. umstellbares Druck-Lackierwerk 1 und nachgeschaltetes Lackierwerk 2 besteht auch die Möglichkeit, gemäß Fig. 2 das nachgeschaltete Lackierwerk 2 zum Kalandrieren zu nutzen, in dem die Lackauftragwalze 11 vom Lackformzylinder 10 abgestellt und dieser als Kalandrierzylinder 15 eingesetzt wird.Deriving from this machine configuration with double coating capability, that is resettable pressure-coating unit 1 and downstream coating unit 2 is also possible, according to FIG. 2, the downstream coating unit 2 to use for calendering in which the lacquer application roller 11 moved away from the coating form cylinders 10 and this as a calendering cylinder 15 is used.

Des weiteren besteht die Möglichkeit, die Lackauftragwalze 11 auch während des Kalandrierens an den Lack- bzw. Kalandrierzylinder 15 anzustellen und ausgehend von der Schöpfwalze 12 oleophiles Trennmittel auf den Kalandrierzylinder 15, zur Verhinderung des Anklebens des Bogens, zu übertragen. In diesem Fall können die Sprühdüsen 17 selbstverständlich entfallen. Furthermore, there is the possibility of also 11 to make the paint applicator roll during calendering to the paint or calendering cylinder 15 and to transmit starting from the pick-up roll 12 oleophilic release agent on the calendering cylinder 15, to prevent sticking of the arc. In this case, the spray nozzles 17 can of course be omitted.

Dadurch ist es möglich geworden, innerhalb eines Maschinendurchlaufes den Druckbogen im Mehrfarbendruck zu bedrucken, ein oder zweimal zu lackieren und durch Kalandrieren zu glätten, so daß eine Oberflächenveredlung erreicht wird, die höchsten Qualitätsansprüchen genügt.This has made it possible within one machine run to print the printing sheet in multi-color printing, to paint once or twice and by calendering to smooth out so that a surface finishing is achieved, the highest quality standards are sufficient.
