Die Erfindung soll an einem Ausführungsbeispiel näher erläutert werden. Dabei zeigen:

Fig. 1
eine Bogenrotationsdruckmaschine mit Offsetdruckwerken und einem zwischen zwei Lackwerken angeordneten Trocknersystem
Fig. 2
ein Trocknersystem mit zwei benachbarten Trocknereinheiten gemäß Fig.1.
The invention will be explained in more detail using an exemplary embodiment. Showing:
Fig. 1
a sheet-fed rotary printing press with offset printing units and a drying system arranged between two coating units
Fig. 2

Eine Mehrfarbenoffsetrotationsdruckmaschine besteht aus mehreren Druckwerken 1, welche jeweils einen Plattenzylinder 8, einen Gummituchzylinder 9 sowie einen Druckzylinder 11 als Bogenführungszylinder aufweisen. Jedem Plattenzylinder 8 ist zumindestens ein nicht näher beschriebenes Farbwerk, gegebenenfalls ein Feuchtwerk zugeordnet.A multi-color offset rotary printing machine consists of a plurality of printing units 1, which each have a plate cylinder 8, a blanket cylinder 9 and a printing cylinder 11 as a sheet guiding cylinder. Each plate cylinder 8 is at least one inking unit not described in detail, optionally associated with a dampening unit.

In Förderrichtung 17 der bogenförmige Bedruckstoffe ist ein erstes Lackwerk 2 dem letzten Druckwerk 1 nachgeordnet. Ein derartiges Lackwerk 2 weist einen Formzylinder 12 und ein zugeordnetes Dosiersystem 13, beispielsweise gebildet aus einem Kammerrakel und einer gerasterten Auftragwalze, und einen Druckzylinder 11 als Bogenführungszylinder auf.In the conveying direction 17 of the sheet-shaped substrates, a first coating unit 2 is arranged downstream of the last printing unit 1. Such a coating unit 2 has a forme cylinder 12 and an associated metering system 13, for example formed from a chambered doctor blade and a screened applicator roller, and a printing cylinder 11 as a sheet guiding cylinder.

Dem ersten Lackwerk 2 folgen in Förderrichtung 17 zwei modular aufgebaute Trocknereinheiten 4. Jede Trocknereinheit 4 besteht u.a. aus zwei Bogenführungszylindern, welche im vorliegenden Beispiel aus einem Transferzylinder 10 und einem Druckzylinder 11 gebildet sind.The first coating unit 2 is followed in the conveying direction 17 by two modular dryer units 4. Each dryer unit 4 is u.a. from two sheet guiding cylinders, which are formed in the present example from a transfer cylinder 10 and a printing cylinder 11.

In Förderrichtung 17 ist der zweiten Trocknereinheit 4 ein zweites Lackwerk 3 nachgeordnet. Das Lackwerk 3 ist analog zum Lackwerk 2 aufgebaut. Jedem Druckzylinder 11 im Druckwerk 1 sowie den Lackwerken 2, 3 ist jeweils ein Transferzylinder 10 als Bogenführungszylinder vorgeordnet. Bezogen auf einen einfachgroßen Formzylinder 12 bzw. Gummituchzylinder 9 (Eintourenwelle) sind alle (einschließlich die der Trocknereinheiten 4) Bogenführungszylinder, Transferzylinder 10 und Druckzylinder 11, doppeltgroß ausgebildet.In the conveying direction 17 of the second dryer unit 4, a second coating unit 3 is arranged downstream. The coating unit 3 is constructed analogously to the coating unit 2. Each printing cylinder 11 in the printing unit 1 and the coating units 2, 3 is preceded in each case by a transfer cylinder 10 as a sheet guiding cylinder. Related to one single-size form cylinder 12 or blanket cylinder 9 (single-turn shaft) are all (including the dryer units 4) sheet guiding cylinder, transfer cylinder 10 and impression cylinder 11, double-sized.

Dem Lackwerk 3 folgt ein nachgeordneter Ausleger 5 mit einem endlos umlaufenden Fördersystem 7, welches die bogenförmigen Bedruckstoffe vom Lackwerk 3 abfördert und auf einem Auslegerstapel 6 ablegt.The coating unit 3 is followed by a downstream boom 5 with an endlessly circulating conveyor system 7, which abfördert the sheet-shaped substrates from the coating unit 3 and stores on a delivery stack 6.

Die in Förderrichtung 17 erste Trocknereinheit 4 weist eine oberhalb des Druckzylinder 11 angeordnete Leiteinrichtung 16 zur Unterstützung der Führung des auf dem Druckzylinder 11 im Greiferschluß fixierten bogenförmigen Bedruckstoffes auf. Beispielsweise ist die Leiteinrichtung 16 durch Leitbügel oder ein Leitblech mit entsprechendem Lochbild oder einer Gitterstruktur ausgebildet. Dem Druckzylinder 11 als Bogenführungszylinder ist oberhalb der Leiteinrichtung 16 eine Trocknervorrichtung 15 innerhalb der ersten Trocknereinheit 4 zugeordnet.The first dryer unit 4 in the conveying direction 17 has a guide device 16 arranged above the printing cylinder 11 for assisting the guidance of the sheet-shaped printing material fixed on the printing cylinder 11 in the gripper closure. For example, the guide 16 is formed by guide bar or baffle with a corresponding hole pattern or a grid structure. The printing cylinder 11 as a sheet guiding cylinder is assigned a drying device 15 within the first dryer unit 4 above the guide 16.

Dieser Trocknervorrichtung 15 ist bei Bedarf in Förderrichtung 17 eine vorzugsweise über die Breite des Druckzylinders 11 sich erstreckende Abschotteinrichtung 14 vorgeordnet.If necessary, this drying device 15 is preceded in the conveying direction 17 by a screeding device 14 which preferably extends over the width of the printing cylinder 11.

Dem Druckzylinder 11 der ersten Trocknereinheit 4 folgt in Förderrichtung 17 die zweite Trocknereinheit 4, welche wiederum einen Transferzylinder 10 und einen nachgeordneten Druckzylinder 11 als Bogenführungszylinder aufweist. Oberhalb dieses Druckzylinders 11 ist eine Leiteinrichtung 16 analog zur ersten Trocknereinheit 4 angeordnet. Oberhalb der Leiteinrichtung 16 ist wiederum einer Trocknervorrichtung 15 dem Druckzylinder 11 in einem definierten Abstand benachbart zugeordnet.The printing cylinder 11 of the first dryer unit 4 is followed in the conveying direction 17 by the second dryer unit 4, which in turn has a transfer cylinder 10 and a downstream printing cylinder 11 as a sheet guiding cylinder. Above this pressure cylinder 11, a guide 16 is arranged analogously to the first dryer unit 4. Above the guide 16, in turn, a drying device 15 is associated with the printing cylinder 11 adjacent to a defined distance.

Dieser Trocknervorrichtung 15 ist bei Bedarf eine vorzugsweise über die Breite des Druckzylinders 11 sich erstreckende Abschotteinrichtung 14 in Förderrichtung 17 nachgeordnet.If necessary, this drying device 15 is followed by a scraper device 14 which preferably extends over the width of the printing cylinder 11 in the conveying direction 17.

Die Verarbeitungstemperaturen in den Trocknereinheiten 4 selbst und den benachbarten Lackwerken 2, 3 sind funktionsstabil. Die Abschotteinrichtungen 14 bilden somit eine Luftabschottung bzw. eine Luftsperre aus. Eine Anordnung der Abschotteinrichtung 14 ist dabei in unmittelbarer Nachbarschaft zu den Trocknervorrichtungen 15 (Figur 2, zweite Trocknereinheit 4) oder in einem definierten Abstand zu den Trocknervorrichtungen 15 (Figur 2, erste Trocknereinheit 4) realisierbar.The processing temperatures in the dryer units 4 themselves and the adjacent coating units 2, 3 are functionally stable. The Abschotteinrichtungen 14 thus form a Luftabschottung or an air lock. An arrangement of the Abschotteinrichtung 14 is in the immediate vicinity of the dryer devices 15 (Figure 2, second dryer unit 4) or at a defined distance from the dryer devices 15 (Figure 2, first dryer unit 4) realized.
