Description

Die Erfindung betrifft eine Vorrichtung zur Nachbehandlung Inline lackierter Druckbogen innerhalb der Druckmaschine. The invention relates to an apparatus for after-treatment in-line painted printed sheets within the printing machine.

Zur Lackierung von Druckbogen in Bogenoffsetdruckmaschinen sind derzeit umstellbare Feucht-Lackierwerke und separate Lackierdruckwerke (Lacktürme) eingesetzt. For the coating of printed sheets in sheet-fed offset presses are currently convertible wet coating units and separate Lackierdruckwerke (coaters) are used. Diese Einrichtungen ermöglichen Glanzlackierungen von genannten Druckbogen und Teilflächen im Inline-Prozeß, sowohl mit einer von beiden Einrichtungen, als auch mit beiden Einrichtungen hintereinander. These devices enable gloss finishes of said printing sheets and partial areas in an inline process, both with one of the two devices, as well as with the two devices in series.

Um ein Ablegen im Stapel zu vermeiden sind diesen Lackiereinrichtungen entsprechende Trockenstrecken nachgeordnet. A drop in the stack to avoid this painting facilities are subordinate corresponding drying sections. Einer der wesentlichsten Gründe für die Lackierung von Druckprodukten ist neben dem Oberflächenschutz und der Scheuerfestigkeit die Erzeugung eines glänzenden Aussehens. One of the main reasons for the finishing of printed products is adjacent to the surface protection and abrasion resistance generating a shiny appearance. Der Grad des Glanzes ist dabei von den Lackeigenschaften, dem Bedruckstoff und der Lackschichtdicke abhängig. The degree of gloss is dependent on the coating properties, the substrate and the coating layer 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 the repeated doping in the printing press to the degree of gloss limits for inline coating, which are mostly due to the surface roughness of the coated printed product.

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. Especially with high quality standards is the inline coating technology for this reason does not apply, but it makes a separate operation in the form of painting or smoothing outside the printing press required.

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 to provide an apparatus for after-treatment in-line painted sheet, whereby a gloss enhancing smoothing within the printing machine is achieved.

Gelöst wird die Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1. The object is achieved by the characterizing features of claim 1.

Die Erfindung soll nachfolgend anhand eines Ausführungsbeispieles näher erläutert werden. The invention will be explained in more detail using an exemplary embodiment.

In der zugehörigen Zeichnung zeigt In the accompanying drawings shows

Fig. 1 eine schematische Darstellung einer Druckmaschine mit separater Lackiereinrichtung und Kalandrierwerk Fig. 1 is a schematic representation of a printing machine with a separate painting facility and Kalandrierwerk

Fig. 2 eine Darstellung gemäß Fig. 1 mit zum Kalandrierwerk umgerüsteter Lackiereinrichtung. Fig. 2 is an illustration of FIG. 1 with the Kalandrierwerk retrofitted painting device.

Die Fig. 1 zeigt die letzten drei Aggregate einer Mehrfarben-Bogenrotationsdruckmaschine, bestehend aus umstellbarem Druck-Lackierwerk 1 , separatem Lackierwerk 2 und Kalandrierwerk 3 . 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 Diese einzelnen Aggregate sind über die Druckzylinder 4 und die Übergabetrommeln 5 untereinander, bis hin zur Auslage, verbunden. These individual units are connected via the impression cylinder 4 and the transfer drums 5 with each other, up to the display.

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 inking system schematically illustrated 6 as well as the convertible wet coating unit 7 are provided on the plate cylinder 8 and the blanket cylinder 9 with the impression cylinder 4 of the printing coating unit 1 in physical contact.

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 impression cylinder 4 of the coating unit 2 is a varnish printing cylinder 10 downstream of which a lacquer application roller 11, a suction roller 12 and a metering roller can be engaged. 13

Im auslaufenden Walzenspalt zwischen Druckzylinder 4 und Gummizylinder 9 sowie Lackformzylinder 10 sind jeweils allgemein bekannte Trockner 14 angestellt. In the outgoing nip between the impression cylinder 4 and the blanket cylinder 9, and coating form cylinders 10 are generally known dryer 14 are employed.

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

Auf den Kalandrierzylinder 15 ist eine Glättplatte 16 mit sehr glatter Oberfläche, z. In the calendering cylinder 15 is a screed plate 16 having a very smooth surface such. B. Chrom aufgespannt. B. Chromium clamped. Zusätzlich ist die Glättplatte 16 mit einer lackabweisenden Schicht belegt, um das Risiko des Lackaufreißens möglichst gering zu halten, auch bei unvollständig angetrocknetem Lack. In addition, the screed plate 16 is covered with a varnish-repellent layer in order to minimize the risk of Lackaufreißens low as possible, even with incomplete dried-coating.

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. Upstream of the inlet zone pressure cylinder 4 - calendering cylinder 15 spray nozzles are additionally arranged 17 to the screed plate 16 may optionally be sprayed with release agent having an oleophilic character and evaporates without residue. Mit dieser Maßnahme soll ein Ankleben der Lackschicht an der Glättplatte 16 vermieden werden. This measure adhesion of the coating layer is to be avoided on the smoothing plate 16th

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. With this additional Kalandrierwerk 3 highest quality standards in respect is suited to the finished surface of the printed product within a machine the run, as in this aggregate smoothed the coating layer by pressing pressure, and thus the gloss effect is achieved.

Ableitend von dieser Maschinenkonfiguration mit doppelter Lackiermöglichkeit, dh 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. Furthermore, there is the possibility to provide the lacquer application roller 11 also during the calendering of the paint or calendering cylinder 15 and starting from the oleophilic scoop roller 12 release agent on the calendering cylinder 15, to be transmitted to prevent sticking of the arc. In diesem Fall können die Sprühdüsen 17 selbstverständlich entfallen. In this case, the spray nozzles can be dispensed 17 course.

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 to print within a machine run by the print sheet in multicolor printing, varnishing or twice and to smooth by calendering, so that a surface decoration is achieved that meets the highest standards of quality.
