Description

Beschreibungdescription
Modulare DruckeinheitModular printing unit
Die Erfindung betrifft eine Druckeinheit zum Bedrucken von Bahnen.The invention relates to a printing unit for printing webs.
Es ist die Aufgabe der Erfindung, eine Druckeinheit zu schaffen, welche mit möglichst geringem baulichen Aufwand und hoher Flexibilität ausgeführt ist.It is the object of the invention to create a printing unit which is designed with the least possible construction effort and high flexibility.
Die Aufgabe wird erfindungsgemäß mit den Merkmalen des Patentanspruchs 1 gelöst.The object is achieved with the features of claim 1.
Die modulare Druckeinheit besteht in vorteilhafter Weise aus drei Hauptgruppen:The modular printing unit advantageously consists of three main groups:
• einem Rahmen, der die tragende Funktion übernimmt sowie alle Installationen und Bedienelemente aufnimmt, alternativ kann auch ein rahmenartig ausgestaltetes Gestell verwendet werden,A frame that takes on the load-bearing function and accommodates all installations and controls, alternatively a frame designed like a frame can also be used,
• im Rahmen oder Gestell gelagerte formatunabhängige "Untereinheiten", welche die zum Druckprozess notwendigen Hilfsbaugruppen enthalten. Beim heute üblichen Offsetverfahren sind dies hauptsächlich Färb- und Feuchtwerke,• Format-independent "sub-units" stored in the frame or frame, which contain the auxiliary modules required for the printing process. In today's usual offset process, these are mainly inking and dampening units,
• mindestens eine als "Riegel" ausgestaltete Traverse, welche im Rahmen angeordnet ist oder beidseitig mit dem Gestell verbunden ist und in denen die zum Drucken notwendigen Hauptbaugruppen - beim Offsetdruck Platten- und Gummizylinder - gelagert sind.• At least one crossbar designed as a "bar", which is arranged in the frame or is connected on both sides to the frame and in which the main assemblies required for printing - in offset printing plate and rubber cylinders - are stored.
Zusätzlich können Zusatzausrüstungen wie z. B. Plattenbeladsysteme oder digitale Bebilderungen (Direktbebilderung) in der Traverse gelagert sein.In addition, additional equipment such. B. plate loading systems or digital images (direct images) can be stored in the traverse.
Jede Traverse ist mit einer oder zwei Schwingen für die sogenannten Druckwerke ausgestattet, um die Gummizylinder zu verschwenken. Ein großer Vorteil dieses Systems ist die Unabhängigkeit vom Druckverfahren, so dass Anpassungen an künftige Neuerungen durch Tausch der entsprechenden Baugruppen zu jeder Zeit möglich sind. Auch die prinzipielle Änderung oder Anpassung an andere Druckverfahren wie auch alle Spielarten des Offsetdrucks können abgedeckt werden. Durch die entsprechende Anpassung der Untereinheiten und/oder der Traverse kann die Druckeinheit aus- oder umgerüstet werden zu Anilox, wasserlosem Offsetdruck, Tiefdruck oder jedem künftig entwickelten Druckverfahren mit dessen Voraussetzungen.Each traverse is equipped with one or two rockers for the so-called printing units in order to pivot the rubber cylinders. A major advantage of this system is the independence from the printing process, so that adjustments to future innovations can be made at any time by exchanging the corresponding modules. The basic change or adaptation to other printing processes as well as all varieties of offset printing can be covered. By adapting the subunits and / or the traverse accordingly, the printing unit can be upgraded or converted to anilox, waterless offset printing, gravure printing or any printing process developed in the future with its requirements.
Eine als H- Druckeinheit ausgestaltete modulare Druckeinheit kann mit 1, 2, 3, 4 oder mehr Druckstellen, eine als I-Druckeinheit ausgestaltete modulare Druckeinheit mit 1 , 2 oder mehr Druckstellen ausgestattet werden. In I-Bauweise können dadurch auch Eindruckwerke gebaut werden. Die Untereinheiten der modularen Druckeinheit sind dazu vormontiert und werden im Rahmen angedockt.A modular printing unit designed as an H printing unit can be equipped with 1, 2, 3, 4 or more printing points, and a modular printing unit configured as an I printing unit can be equipped with 1, 2 or more printing points. Imprints can also be built in I construction. The sub-units of the modular printing unit are preassembled and docked in the frame.
Das Verhältnis der in der Traverse gelagerten Plattenzylinder zu Gummizylinder kann x:x oder x:y (für y > x) betragen, vorteilhafter Weise aber 1 :1 , 1 :2 und 2:2. Genauso vorstellbar sind jedoch auch 2:3, 3:3 usw.The ratio of the plate cylinders to blanket cylinders mounted in the crossbeam can be x: x or x: y (for y> x), but advantageously 1: 1, 1: 2 and 2: 2. However, 2: 3, 3: 3, etc. are equally conceivable.
Der Wandanteil für Färb- und Feuchtwerke ist getrennt vom Wandanteil für Plattenzylinder und Gummizylinder und wird hier "Untereinheit" genannt. Das Farbwerk kann alternativ 1 , 2, 3 oder 4 und mehr Farbauftragwalzen enthalten sowie beliebig viele Reibzylinder. Das Feuchtwerk kann alternativ 1 oder 2 Feuchtmittelübertragungswalzen enthalten sowie beliebig viele Reibzylinder. Farb- und Feuchtwerke können auch mit einer oder mehrer "Koppelwalzen" für indirekte Feuchtung verbunden werden.The wall portion for inking and dampening units is separate from the wall portion for plate cylinders and blanket cylinders and is called "subunit" here. The inking unit can alternatively contain 1, 2, 3 or 4 and more inking rollers as well as any number of distribution cylinders. The dampening unit can alternatively contain 1 or 2 dampening solution transfer rollers as well as any number of distribution cylinders. Ink and dampening systems can also be connected to one or more "coupling rollers" for indirect dampening.
Der Gummizylinder wird für gute Zugänglichkeit (z.B. Tausch des Gummizylinderüberzugs, Entfernen eines Wicklers) mittels der in der Traverse angeordneten Schwinge herausgeschwenkt, der Drehpunkt dazu liegt in vorteilhafter Weise auf Mitte Plattenzylinder. Translatorische Bewegungen sind nicht zwingend notwendig, es besteht aber die Möglichkeit die in der Traverse angeordneten Gegendruck-, Gummi- und Plattenzylinder in translatorischer Richtung zueinander zu verschieben. Die Untereinheiten sind in modularer Bauweise ausgeführt, welche in vorteilhafter Weise identisch aufgebaut sind, wobei diese hauptsächlich Färb- und Feuchtwerke aufnehmen. Durch den identischen Aufbau der Untereinheiten können diese in vorteilhafter Weise mit gleichen Abmessungen ausgestaltet werden, was die Austauschbarkeit verbessert und die Herstellungskosten minimiert.The rubber cylinder is swiveled out for good accessibility (eg replacement of the rubber cylinder cover, removal of a winder) by means of the rocker arranged in the crossmember, the fulcrum advantageously lies on the middle of the plate cylinder. Translatory movements are not absolutely necessary, but there is the possibility of shifting the counter-pressure, rubber and plate cylinders arranged in the traverse in the translational direction. The subunits are designed in a modular design, which are advantageously constructed identically, these mainly taking up dyeing and dampening units. Due to the identical structure of the subunits, they can advantageously be designed with the same dimensions, which improves interchangeability and minimizes production costs.
Daraus lassen sich bei identischen UntereinheitenThis can be used for identical subunits
a) H-Druckeinheiten mit identischer Höhe und gegebenenfalls formatabhängig unterschiedlicher Breite mit waagrechter Traverse sowie b) I-Druckeinheiten mit identischer Breite und gegebenenfalls formatabhängig unterschiedlicher Höhe mit senkrechter Traverse ableiten.a) Derive H-printing units with identical height and, if applicable, format-dependent different widths with horizontal traverse as well as b) I-printing units with identical width and possibly format-dependent, different height with vertical traverse.
Durch die Kombination einer oberen linken und unteren rechten in Modulbauweise ausgeführten Untereinheit lässt sich eine I-Druckeinheit für eine Links- Rechts- Maschine bauen, durch die Kombination einer oberen rechten und unteren linken in Modulbauweise ausgeführten Untereinheit lässt sich eine I-Druckeinheit für eine Rechts- Links-Maschine bauen.By combining an upper left and lower right modular unit, an I-printing unit for a left-right machine can be built, and by combining an upper right and lower left modular unit, an I-printing unit can be built for a right - Build left machine.
Die Zylinder für Plattenzylinder und Gummizylinder können in der Traverse gestreckt - d.h. in einer Linie - , geschränkt in jedwede Richtung oder winklig zueinander angeordnet sein.The cylinders for plate cylinders and blanket cylinders can be stretched in the traverse - i.e. in a line -, set in any direction or at an angle to each other.
Die modulare Druckeinheit kann mit verschiedenen Antriebsarten ausgerüstet sein:The modular printing unit can be equipped with different drive types:
• H-Antrieb für den gleichzeitigen Antrieb von vier Druckwerken, integriert im Rahmen• H drive for the simultaneous drive of four printing units, integrated in the frame
• Brückenantrieb für den gleichzeitigen Antrieb von zwei Druckwerken, integriert in der Traverse, vorteilhafter Weise auf Mitte Plattenzylinder positioniert und den Gummizylinder über Antriebselemente antreibend• Bridge drive for the simultaneous drive of two printing units, integrated in the traverse, advantageously positioned in the middle of the plate cylinder and driving the rubber cylinder via drive elements
• Einzelantrieb für jedes Druckwerk, integriert in der Traverse, vorteilhafter Weise auf Mitte Plattenzylinder positioniert und den Gummizylinder über Antriebselemente antreiben, oder integriert in der jeweiligen Untereinheit. Für die Druckan- und Druckabstellung sind Plattenzylinder und Gummizylinder über Exzenter zueinander beweglich.• Individual drive for each printing unit, integrated in the traverse, advantageously positioned in the middle of the plate cylinder and driving the rubber cylinder via drive elements, or integrated in the respective subunit. The plate cylinder and blanket cylinder can be moved relative to each other via eccentrics for printing on and off.
Die Rahmen, Traversen und Schwingen sind konstruktiv einfach und dadurch kostengünstig erstellbar. So sind beispielsweise die Traversen mit handelsüblichen Profilen realisierbar. Auch zeichnen sich die mittels des Rahmens, der Traversen und der Schwingen ausgestalteten Druckeinheiten durch eine gewichtsreduzierte, kompakte und platzsparende Bauweise aus.The frames, trusses and swing arms are structurally simple and therefore inexpensive to produce. For example, the trusses can be realized with commercially available profiles. The printing units designed by means of the frame, the traverses and the rockers are also characterized by a weight-reduced, compact and space-saving design.
So ist mit ein und derselben Druckeinheit wahlweise im Tiefdruck- oder Offsetdruckverfahren druckbar, wobei die Maschine einfach durch die Modulbauweise und den Austausch der mit den entsprechenden Zylindern bestückten Traverse und Austausch der entsprechenden modulartigen Untereinheiten von dem einen auf das andere Verfahren umbaubar ist. Auch können beide Druckverfahren gleichzeitig zur Anwendung kommen. Darüber hinaus kann beispielsweise das eine Druckverfahren für den Schöndruck und das andere Druckverfahren für den Widerdruck angewandt werden. Der Druckmaschinenhersteller kann die Maschinen für beide Verfahren gleichartig aus gleichen Bauteilen erstellen, was eine kostengünstige Fertigung ermöglicht. Auch sind die Druckeinrichtungen im Format variabel ausführbar, d. h. sie können einfach auf andere Formate, also andere Durchmesser der Druckwerkzylinder und Abschnittlängen, umgerüstet werden. Weiterhin ist die Druckeinheit schnell auf verschiedene Produktionsvarianten umstellbar. Darüber hinaus kann die Druckeinheit auch in eine Lackiereinrichtung oder zumindest entweder für den Schöndruck oder für den Widerdruck als Lackierwerk umgerüstet werden.For example, one and the same printing unit can be used for rotogravure or offset printing, whereby the machine can be converted from one process to the other simply by the modular design and the exchange of the traverse equipped with the corresponding cylinders and replacement of the corresponding modular subunits. Both printing processes can also be used simultaneously. In addition, for example, one printing process can be used for straight printing and the other printing process for reverse printing. The printing press manufacturer can create the machines for both processes in the same way from the same components, which enables cost-effective production. The printing devices are also variable in format, i. H. they can easily be converted to other formats, i.e. different diameters of the printing unit cylinders and section lengths. Furthermore, the printing unit can be quickly converted to different production variants. In addition, the printing unit can also be converted into a coating device or at least either for face printing or for reverse printing as a coating unit.
Bedeutungsvoll ist, dass eine Druckeinheit in Modulbauweise zum Bedrucken von Bahnen geschaffen wird, die ein Gestell aufweist, das an beiden Stirnseiten (Antriebs- und Bedienseite) mit mindestens einer Traverse versehen ist, wobei in den Traversen Druckzylinder gelagert sind, derart dass eine Baueinheit aus Traversen und Druckzylindern komplett aus dem Gestell heraus- und hereinnehmbar ist.It is important that a printing unit in modular design for printing webs is created, which has a frame that is provided on both end faces (drive and operating side) with at least one cross member, with pressure cylinders being mounted in the cross members, such that a structural unit is made up of Trusses and pressure cylinders are completely removable and removable from the frame.

Sie können, nicht näher dargestellt, in der Traverse 3; 4 geschränkt in jedwede Richtung oder winklig zueinander angeordnet sein. Jedes Druckwerk 5 bis 8 bzw. jeder Plattenzylinder 9 bis 12 steht mit einer modulartig aufgebauten Untereinheit 17 bis 20 in Verbindung, wobei die Untereinheit 17 bis 20 zwischen der jeweiligen Traverse 3; 4 und dem Gestell 2 angeordnet ist. In den Untereinheiten 17 bis 20 sind, nicht näher dargestellt, Färb- und Feuchtwerke integriert. Die derart mit vier Druckwerken 5 bis 8 ausgestaltete Druckeinheit 1 stellt eine sogenannte H-Druckeinheit mit vier Druckstellen dar, wobei eine zu bedruckende Bahn 29 zwischen den Gummizylindern 13 bis 16 hindurchgeführt ist. Die Druckwerke 5 bis 8 bedrucken die Bahn 29 beidseitig. Alternativ kann der Gummizylinder 13; 15 oder der Gummizylinder 14; 16 als Gegendruckzylinder 50 ausgestaltet sein, wobei der jeweilige Formzylinder 9 bis 12 zum nun als Gegendruckzylinder 42 ausgeführten Gummizylinder 13 bis 16 entfällt. Somit wird die Bahn 29 einseitig bedruckt.FIG. 1 shows a printing unit 1 of a web-fed rotary printing press consisting of a frame 2 constructed in the manner of a frame with two cross members 3 to be connected to it on both sides; 4, wherein in the trusses 3; 4 two printing units 5 to 8 with plate cylinders 9 to 12 and blanket cylinders 13 to 16 are arranged and the cross members 3; 4 are arranged horizontally in frame 2.

Blechprofilen.Sheet metal profiles.
Die Druckzylinder 9 bis 16 sind für die Druckan- /Druckabstellung über als Exzenter ausgestaltete Lagerstellen zueinander beweglich.The printing cylinders 9 to 16 can be moved relative to one another for the printing on / printing off via bearing points designed as eccentrics.
Figur 2 zeigt einen Antrieb 30 des Druckwerkes 5. Der Antrieb 30 besteht aus einem Antriebsmotor 31, der über eine Kupplung 32 mit dem Plattenzylinder 9 in Antriebsverbindung steht. Der Plattenzylinder 9 ist mit dem Gummizylinder 13 über an ihren Achsen 25; 35 angeordneten Zahnrädern 33; 34 verbunden. Der Antriebsmotor 31 ist an einer mit der Traverse 3 verbundenen Konsole 36 angeordnet. Auf der Achse 25 des Plattenzylinders 9 ist die Schwinge 21 gelagert, welche mittels eines an der Konsole 36 befestigten und mit einem an der Schwinge 21 angeordneten Zahnsegmentes 37 im Eingriff befindlichen Ausschwenkmotors 38 um die Achse 25 verschwenkt werden kann. Vor dem Verschwenken muss eine Verriegelungseinrichtung 39 gelöst werden, welche bei Druckbetrieb die Schwinge 21 mit der Konsole 36 in arretierender Weise verbindet. Es versteht sich von selbst, dass die Traverse 3 entlang des Verschwenkweges der Achse 35 des Gummizylinders 13 mit einer Aussparung 40 ausgestaltet ist. Nicht näher dargestellt kann die Schwinge 21 auch mittels eines druckmittelbetriebenen Arbeitszylinders anstatt mittels des Ausschwenkmotors verschwenkt werden.FIG. 2 shows a drive 30 of the printing unit 5. The drive 30 consists of a drive motor 31 which is in drive connection with the plate cylinder 9 via a coupling 32. The plate cylinder 9 is with the rubber cylinder 13 on their axes 25; 35 arranged gears 33; 34 connected. The drive motor 31 is arranged on a bracket 36 connected to the cross member 3. On the axis 25 of the plate cylinder 9, the rocker 21 is mounted, which can be pivoted about the axis 25 by means of a pivoting motor 38 which is fastened to the bracket 36 and is in engagement with a toothed segment 37 arranged on the rocker 21. Before pivoting, a locking device 39 must be released, which connects the rocker 21 to the bracket 36 in a locking manner during printing operation. It goes without saying that the crossmember 3 is provided with a cutout 40 along the pivoting path of the axis 35 of the rubber cylinder 13. Not shown in detail, the rocker 21 can also be pivoted by means of a pressure medium-operated working cylinder instead of by means of the swing-out motor.
