Description

Die Erfindung betrifft eine Druckeinheit zum Bedrucken von Bahnen.The invention relates to a printing unit for printing webs.

Aus dem Stand der Technik ist die DE 198 33 468 A1 bekannt, die eine Druckeinheit in Modulbauweise zum Bedrucken von Bahnen aufweist.From the prior art is the DE 198 33 468 A1 known, which has a printing unit in modular design for printing on webs.

Es ist Aufgabe der Erfindung, eine Druckeinheit zu schaffen, welche mit möglichst geringem baulichen Aufwand und hoher Flexibilität auskommt.It is an object of the invention to provide a printing unit, which manages with minimal structural complexity and high flexibility.

Die Aufgabe wird erfingdungsgemäß mit dem kennzeichnenden Merkmal des Patentanspruches 1 gelöst. Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.The object is achieved erfingdungsgemäß with the characterizing feature of claim 1. Further advantageous embodiments of the invention are specified in the subclaims.

Die modulare Druckeinheit besteht in vorteilhafter Weise aus drei Hauptgruppen:

  • einem Rahmen, der die tragende Funktion übernimmt sowie alle Installationen und Bedienelemente aufnimmt, alternativ kann auch ein rahmenartig ausgestaltetes Gestell verwendet werden,
  • im Rahmen oder Gestell gelagerte formatunabhängige "Untereinheiten", welche die zum Druckprozess notwendigen Hilfsbaugruppen enthalten. Beim heute üblichen Offsetverfahren sind dies hauptsächlich Farb- und Feuchtwerke,
  • 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.
    Zusätzlich können Zusatzausrüstungen wie z.B. Plattenbeladesysteme oder digitale Bebilderung (Direktbebilderung) in der Traverse gelagert sein.
The modular printing unit advantageously consists of three main groups:
  • a frame that takes over the supporting function and accommodates all installations and operating elements, alternatively, a frame-like designed frame can be used,
  • in the frame or frame stored format-independent "subunits", which contain the necessary for the printing process auxiliary modules. In today's conventional offset process, these are mainly inking and dampening,
  • at least one designed as a "bar" traverse, which is arranged in the frame or is connected to both sides of the frame and in which the necessary for printing main modules - the offset printing plate and blanket cylinder - are stored.
    In addition, additional equipment such as plate loading systems or digital imaging (direct imaging) can be stored in the traverse.

Jede Traverse ist mit einer oder zwei Schwingen für die sogenannten Druckwerke ausgestattet, um die Gummizylinder zu verschwenken.Each truss is equipped with one or two wings for the so-called printing units to pivot the blanket cylinders.

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.A great advantage of this system is the independence of the printing process, so that adaptations to future innovations by exchanging the corresponding assemblies are possible at any time. Also, the principal change or adaptation to other printing methods as well as all varieties of offset printing can be covered. By adapting the sub-units and / or the traverse, the printing unit can be converted or converted to anilox, waterless offset printing, gravure printing or any future developed printing process 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 configured as an H printing unit can be equipped with 1, 2, 3, 4 or more printing areas, a modular printing unit designed as an I printing unit with 1, 2 or more printing sites. In I construction, imprints can also be built. The subunits of the modular printing unit are pre-assembled 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 stored in the traverse to rubber cylinders can be x: x or x: y (for y> x), but advantageously 1: 1, 1: 2 and 2: 2. However, equally conceivable are 2: 3, 3: 3, etc.

Der Wandanteil für Farb- 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 separated from the wall portion for plate cylinder and blanket cylinder and is here called "subunit". The inking unit may alternatively contain 1, 2, 3 or 4 and more inking rollers and 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. Dyeing and dampening units can also be combined with 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.The blanket cylinder is swung out for good accessibility (eg exchange of the rubber cylinder cover, removal of a winder) by means of the arranged in the crossmember swingarm, the fulcrum is located in an advantageous manner on center plate cylinder. Translational movements are not absolutely necessary, but it is possible to move the arranged in the traverse back pressure, rubber and plate cylinder in translational direction to each other.

Die Untereinheiten sind in modularer Bauweise ausgeführt, welche in vorteilhafter Weise identisch aufgebaut sind, wobei diese hauptsächlich Farb- 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 subunits are designed in a modular design, which are constructed identically in an advantageous manner, which absorb mainly dyeing and dampening. Due to the identical structure of the subunits they can be designed in an advantageous manner with the same dimensions, which improves the interchangeability and minimizes the manufacturing cost.

Daraus lassen sich bei identischen Untereinheiten

  1. a) H-Druckeinheiten mit identischer Höhe und gegebenenfalls formatabhängig unterschiedlicher Breite mit waagrechter Traverse sowie
  2. b) I-Druckeinheiten mit identischer Breite und gegebenenfalls formatabhängig unterschiedlicher Höhe mit senkrechter Traverse
ableiten.This can be done with identical subunits
  1. a) H-pressure units with identical height and, where appropriate format dependent different width with horizontal crosshead and
  2. b) I-printing units with identical width and, where appropriate format dependent different height with vertical crosshead
derived.

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.The combination of upper left and lower right modular subassemblies makes it possible to build an I-press unit for a left-right machine, and the combination of upper left and lower left modular subassemblies makes it possible to produce an I-press unit for a right - Build Links 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. in a line -, be set in any direction or at an angle to each other.

Die modulare Druckeinheit kann mit verschiedenen Antriebsarten ausgerüstet sein:

  • H-Antrieb für den gleichzeitigen Antrieb von vier Druckwerken, integriert im Rahmen
  • Brückenantrieb für den gleichzeitigen Antrieb von zwei Druckwerken, integriert in der Traverse, vorteilhafter Weise auf Mitte Plattenzylinder positioniert und den Gummizylinder über Antriebselemente antreibend
  • 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.
The modular printing unit can be equipped with different drive types:
  • H-drive for the simultaneous drive of four printing units, integrated in the frame
  • Bridge drive for the simultaneous drive of two printing units, integrated in the traverse, advantageously positioned on the center plate cylinder and driving the blanket cylinder via drive elements
  • Single drive for each printing unit, integrated in the traverse, advantageously positioned on center plate cylinder and drive the blanket cylinder via drive elements, or integrated in the respective subunit.

Für die Druckan- und Druckabstellung sind Plattenzylinder und Gummizylinder über Exzenter zueinander beweglich.For Druckan- and print shutoff plate cylinder and blanket cylinder via eccentric are mutually movable.

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 are structurally simple and thus inexpensive to build. Thus, for example, the trusses with commercial profiles can be realized. Also, the pressure units designed by means of the frame, the traverses and the wings are 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.Thus, with one and the same printing unit either in the gravure printing or offset printing process printable, the machine is easily convertible by the modular design and replacement of the equipped with the corresponding cylinders Traverse and replacement of the corresponding modular subunits from one to the other method. Also, both printing methods can be used simultaneously. In addition, for example, the one printing method for the Perfecting and the other printing method for the perfecting can be applied. The printing press manufacturer can make the machines for both processes equally from the same components, which enables a cost-effective production. Also, the printing devices in the format are variable executable, d. H. they can easily be converted to other formats, ie different diameters of the printing cylinder and section lengths. Furthermore, the printing unit is quickly convertible to different production variants. In addition, the printing unit can also be converted into a painting or at least either for the Perfecting or for the perfecting as Lackierwerk.

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 significant that a printing unit is created in modular design for printing on webs, which has a frame which is provided on both end sides (drive and operating side) with at least one cross member, wherein in the traverse impression cylinders are mounted, such that a structural unit of Trusses and pressure cylinders completely out of the frame out and ingestable.

Die Traverse 3; 4 ist, nicht näher dargestellt, beidseitig mit dem Gestell 2 verschraubt, so dass beispielsweise ein Austausch der jeweiligen Druckwerke 5 bis 8 schnell bewerkstelligt werden kann.Traverse 3; 4 is, not shown in detail, screwed on both sides with the frame 2, so that, for example, an exchange of the respective printing units 5 to 8 can be accomplished quickly.

Die Traverse 3; 4 besteht beispielsweise aus abgekanteten Blechen oder Blechprofilen.Traverse 3; 4 consists for example of folded sheets or 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 are movable relative to each other for the Druckan- / Druckabstellung designed as an eccentric bearings.

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 connected via a clutch 32 to the plate cylinder 9 in drive connection. The plate cylinder 9 is connected to the blanket cylinder 13 on at their axes 25; 35 arranged gears 33; 34 connected. The drive motor 31 is arranged on a console 36 connected to the crossmember 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 an attached to the bracket 36 and arranged with a arranged on the rocker 21 gear segment 37 Ausschwenkmotors 38. Before pivoting a locking device 39 must be solved, which connects the rocker 21 with the console 36 in a locking manner in printing operation. It goes without saying that the traverse 3 along the Verschwenkweges the axis 35 of the blanket cylinder 13 is configured with a recess 40. Not shown in detail, the rocker 21 can be pivoted by means of a fluid-operated working cylinder instead of means of the Ausschwenkmotors.

Figur 3 zeigt eine Variante zur Figur 2. Der Antriebsmotor 31 treibt hier den Gummizylinder 13 beispielsweise über ein Antriebselement 41, beispielsweise einen Zahnriemen, an. Der Antriebsmotor 31 liegt analog zu Fig. 2 in seiner Position auf Mitte MP des Plattenzylinders 9, damit er beim Ausschwenken des Gummizylinders 13 seine Position nicht ändert. FIG. 3 shows a variant of FIG. 2 , The drive motor 31 drives here the blanket cylinder 13, for example via a drive element 41, for example a Timing belt, on. The drive motor 31 is analogous to Fig. 2 in its position on the center M P of the plate cylinder 9 so that it does not change its position when swinging the rubber cylinder 13.

Figur 4 zeigt eine Druckeinheit 50, welche als I-Druckeinheit ausgestaltet ist. Bei einer I-Druckeinheit 50 ist die Traverse 51 beispielsweise T-förmig ausgestaltet und die Bahn 29 wird in horizontaler Richtung durch die Druckeinheit 50 geführt. Die I-Druckeinheit 50 kann mit 1 oder 2 Druckstellen ausgestattet werden. Somit können in I-Bauweise auch Eindruckwerke gebaut werden. Die Untereinheiten 52; 53 sind dazu analog zu Fig. 1 vormontiert und werden im Gestell 54 angedockt. FIG. 4 shows a printing unit 50, which is designed as an I-printing unit. In an I-pressure unit 50, the cross member 51 is configured, for example, T-shaped and the web 29 is guided in a horizontal direction by the printing unit 50. The I-pressure unit 50 can be equipped with 1 or 2 pressure points. Thus, imprints can be built in I-construction. Subunits 52; 53 are analogous to Fig. 1 pre-assembled and docked in rack 54.

Durch die Kombination eines oberen linken 52 und unteren rechten in Modulbauweise ausgeführten Untereinheit 53 lässt sich eine I-Druckeinheit 50 für eine Links- Rechts-Maschine bauen (siehe Fig. 4, obere Abbildung), durch die Kombination eines oberen rechten 55 und unteren linken in Modulbauweise ausgeführten Untereinheit 56 lässt sich eine I-Druckeinheit 50 für eine Rechts- Links-Maschine bauen (siehe Fig. 4, untere Abbildung).By combining a top left 52 and bottom right modular subassembly 53, an I-pressure unit 50 can be built for a left-right machine (see FIG Fig. 4 , upper figure), by combining a top right 55 and bottom left modular subassembly 56, an I-press unit 50 for a right-left machine can be built (see FIG Fig. 4 , bottom picture).

In Figur 5 sind die Untereinheiten 17 bis 20 gezeigt. Die Untereinheiten 17 bis 20 weisen immer die gleichen Abmessungen auf, wobei die Gestelle 2; 2' in ihrem Format bzw. in ihren Abmessungen unterschiedlich sein können, wobei die Abmessung bzw. das Format der Gestelle 2; 2' von der Anzahl und der Dimension der verwendeten Druckzylinder abhängig ist. Während des Betrachtens der beiden in Figur 5 dargestellten Abbildungen erkennt man die gleich dimensionierten Untereinheiten 17 bis 20, jedoch den mit ΔB dargestellten Formatunterschied der Gestelle 2; 2'.In FIG. 5 subunits 17-20 are shown. The subunits 17 to 20 always have the same dimensions, the racks 2; 2 'in their format or in their dimensions may be different, wherein the size or the format of the frames 2; 2 'is dependent on the number and the dimension of the printing cylinder used. While looking at the two in FIG. 5 Illustrated figures can be seen the same sized subunits 17 to 20, but the format difference of the frames 2 shown with ΔB; 2 '.
