Description

Gegenstand der Erfindung ist eine Rotationsdruckmaschine vorzugsweise für Etikettendruck mit konzentrisch um zwei oder mehrere Gegendruckzylinder angeordneten Druckwerken verschiedener Druckverfahren.The invention relates to a rotary printing press, preferably for label printing with printing units of different printing processes arranged concentrically around two or more impression cylinders.

Zentrale Gegendruckzylinder, um die mehrere Druckwerke angeordnet sind, sind seit Jahrzehnten bekannt.Central impression cylinders around which several printing units are arranged have been known for decades.

Die Vorteile zentraler Gegendruckzylinder für die Anordnung einer Vielzahl von Druckwerken um den Umfang des Gegendruckzylinders haben gegenüber bekannten, nacheinander angeordneten Druckwerken mit je einem, dem Druckwerk zugeordneten Gegendruckzylinder nicht nur den Vorteil kompakter Bauweise, sondern vor allem bei dehnungskritischen Bedruckstoffen den Vorteil, daß der Bedruckstoff während der Bearbeitung durch mehrere, um den Gegendruckzylinder nacheinander angeordnete Druckwerke ständig auf dem Gegendruckzylinder aufliegt. Dadurch wird erreicht, daß regelmässig keine zusätzlichen Regeleinrichtungen, die heute überwiegend elektronisch gesteuert werden, für die Kontrolle der Passergenauigkeit benötigt werden.The advantages of central impression cylinders for the arrangement of a large number of printing units around the circumference of the impression cylinder have not only the advantage of a compact design compared to known, successively arranged printing units, each with an impression cylinder assigned to the printing unit, but above all in the case of stretch-critical substrates that the substrate during processing by a plurality of printing units arranged one after the other around the impression cylinder constantly rests on the impression cylinder. It is thereby achieved that no additional control devices, which are predominantly electronically controlled today, are regularly required for checking the registration accuracy.

Zentrale Gegendruckzylinder mit konzentrisch angeordneten Druckwerken haben dagegen gegenüber horizontal oder vertikal angeordneten Druckwerken mit je einem Gegendruckzylinder den Nachteil, daß durch die notwendige Beschränkung des Durchmessers und damit des Umfanges des Gegendruckzylinders die Anzahl der auf dem Umfang des Gegendruckzylinders angeordneten Druckwerke beschränkt ist. Bei einer beliebigen Vergrösserung des Umfanges eines Gegendruckzylinders sind nicht nur die im oberen Breich angeordneten Druckwerke schlecht zugänglich. Mit der Zunahme des Umfanges wird auch die notwendige Rundheit des Zylinders kostenverhältnismässig nicht mehr beherschbar. Schliesslich ist bei der Anordnung von mehr als vier Druckwerken von Nachteil, daß sich bei im oberen und unteren Bereich des Gegendruckzylinders angeordneten Druckwerken, die notwendigerweise horizontal angeordnet sein müssen, der Andruckwinkel gegenüber der möglichst horizontalen Druckrichtung vergrössert.Central impression cylinders with concentrically arranged printing units, on the other hand, have the disadvantage compared to horizontally or vertically arranged printing units, each with an impression cylinder, that the number of printing units arranged on the circumference of the impression cylinder is limited by the necessary restriction of the diameter and thus the circumference of the impression cylinder. With an arbitrary enlargement of the circumference of an impression cylinder, not only the printing units arranged in the upper area are difficult to access. With the increase in the circumference, the necessary roundness of the cylinder is no longer manageable in terms of cost. Finally, with the arrangement of more than four printing units, it is disadvantageous that in the case of printing units arranged in the upper and lower region of the impression cylinder, which must necessarily be arranged horizontally, the contact angle increases with respect to the printing direction which is as horizontal as possible.

Ein weiterer Nachteil eines zentralen Gegendruckzylinders ist ferner, daß nur Druckverfahren verwendet werden können, denen die Oberfläche des Gegendruckzylinders entspricht.Another disadvantage of a central impression cylinder is that only printing processes can be used which correspond to the surface of the impression cylinder.

Aufgabe der Erfindung ist es, unter Wahrung der Vorteile zentraler Gegendruckzylinder eine Lösung zu finden, die nicht nur die Anordnung von einer gegenüber herkömmlichen Lösungen vermehrten Anzahl von Druckwerken gestattet, sondern auch die Verwendung mehrerer Druckverfahren durch mehrere Druckwerke erlaubt.The object of the invention is to find a solution while preserving the advantages of central impression cylinders, which not only allows the arrangement of an increased number of printing units compared to conventional solutions, but also allows the use of several printing methods by several printing units.

Erfindungsgemäss werden zwei oder mehrere Gegendruckzylinder verwendet, die auf einer einseitig gelagerten Achse angeordnet sind. Zu den Gegendruckzylindern sind in parallelen Ebenen Druckwerke bekannter Art angeordnet. Ferner ist nach dem in Bahnlaufrichtung letzten Druckwerk des ersten Gegendruckzylinders eine BahnversetzVorrichtung angeordnet, durch die die Bahn von dem ersten auf den zweiten Gegendruckzylinder geführt wird.According to the invention, two or more impression cylinders are used, which are arranged on an axle mounted on one side. Printing units of a known type are arranged in parallel planes with the impression cylinders. Furthermore, a web offset device is arranged after the last printing unit of the first impression cylinder in the direction of web travel, through which the web is guided from the first to the second impression cylinder.

Die erfindungsgemässe Anordnung von zwei oder mehreren Gegendruckzylindern auf einer Achse hat zunächst den Vorteil, daß gegenüber bekannten Rotationsdruckmaschinen mit nur einem Gegendruckzylinder der Durchmesser der Gegendruckzylinder auf ein beherrschbares Mass beschränkt und die Anzahl der um den jeweiligen Gegendruckzylinder angeordneten Druckwerke und der zugeordneten Trocknungsvorrichtungen verringert werden kann. Werden bei bekannten Rotationsdruckmaschinen bis zu sechs Druckwerke um einen Gegendruckzylinder angeordnet, so kann bei der erfindungsgemässen Anordnung die Zahl der Druckwerke pro Gegendruckzylinder auf zwei bis vier beschränkt werden. Die hat nicht nur den Vorteil, daß die Bahn-Auflaufstrecke auf dem Gegendruckzylinder so verlängert werden kann, daß sich die Bahn auf dem Gegendruckzylinder stabilisiert hat, bevor sie das erste Druckwerk erreicht, sondern auch den weiteren Vorteil, daß der Abstand zwischen den einzelnen Druckwerken vergrössert werden kann. Damit wird nicht nur die nach jedem Druckwerk notwendige Farbtrocknung optimiert. Es lassen sich auch weniger gross dimensionierte und damit energiesparende-Trocknungseinrichtungen verwenden.The arrangement according to the invention of two or more impression cylinders on one axis initially has the advantage that, compared to known rotary printing presses with only one impression cylinder, the diameter of the impression cylinders is limited to a manageable level and the number of printing units arranged around the respective impression cylinder and the associated drying devices can be reduced . If up to six printing units are arranged around an impression cylinder in known rotary printing presses, the number of printing units per impression cylinder can be limited to two to four in the arrangement according to the invention. This not only has the advantage that the web run-up path on the impression cylinder can be extended so that the web on the impression cylinder has stabilized before it reaches the first printing unit, but also the further advantage that the distance between the individual printing units can be enlarged. This not only optimizes the ink drying required after each printing unit. Less large-sized and thus energy-saving drying devices can also be used.

Die erfindungsgemässe Anordnung hat ferner den Vorteil, daß unterschiedliche Druckverfahren wie Flexodruck und Buchdruck, die eine weiche oder harte Gegendruckzylinder-Oberfläche erfordern, verwendet werden können, in dem die Gegendruckzylinder mit unterschiedlich harten, dem jeweils verwendeten Druckverfahren entsprechenden Manteloberflächen versehen sind.The arrangement according to the invention also has the advantage that different printing methods such as flexographic printing and letterpress, which require a soft or hard impression cylinder surface, can be used in which the impression cylinders are provided with jacket surfaces of different hardness corresponding to the printing method used.

Da bei unterschiedlichen Druckverfahren mit unterschiedlichen Oberflächen des Gegendruckzylinders geringfügige, durch die Oberflächenverformung beim Drucken entstehende Umfangs-Differenzen der Gegendruckzylinder auftreten können, ist es vorteilhaft, die Gegendruckzylinder unabhängig voneinander anzutreiben. So kann beispielsweise bei einem gemeinsamen Antrieb beider Gegendruckzylinder die Umfangsgeschwindigkeit des einen Gegendruckzylinders mittels eines Überlagerungsgetriebes vergrössert werden.Since, with different printing processes with different surfaces of the impression cylinder, slight circumferential differences of the impression cylinders resulting from the surface deformation during printing can occur, it is advantageous to drive the impression cylinders independently of one another. For example, with a common drive of both impression cylinders, the peripheral speed of one impression cylinder can be increased by means of a superposition gear.

Die Gegendruckzylinder können aber auch durch getrennte Einzelantriebe angetrieben werden.The impression cylinders can also be driven by separate individual drives.

Um den Aus- und Einbau eines Gegendruckzylinders mit einer anderen Manteloberfläche zu vermeiden, ist es vorteilhaft Gegendruckzylinder zu verwenden, die mit einer lösbaren Stahlrohrmanschette versehen sind, die ihrerseits eine einem bestimmten Druckverfahren angepasste Oberfläche aufweisen. Vorzugsweise werden solche Manschetten mittels Öldruckverbund auf dem Gegendruckzylinder befestigt.In order to avoid the removal and installation of a counter-pressure cylinder with a different jacket surface, it is advantageous to use counter-pressure cylinders which are provided with a detachable tubular steel sleeve, which in turn have a surface adapted to a specific printing process. Such sleeves are preferably attached to the impression cylinder by means of an oil pressure compound.

Die erfindungsgemässe Bahnversetzvorrichtung besteht aus zwei in bestimmtem Winkel zur Bahnrichtung und in bestimmtem Abstand zueinander angeordneten, fest gelagerten, parallel zueinander angeordneten Rundstäben, wobei zur parallelen Bahnüberführüng der Winkel 45° beträgt und der Abstand der Bahnbreite bzw. der Breite des Gegendruckzylindermantels entspricht.The web transfer device according to the invention consists of two fixed rods which are arranged at a specific angle to the web direction and at a specific distance from one another and are arranged parallel to one another, the angle for the parallel web transfer being 45 ° and the distance corresponding to the web width or the width of the impression cylinder jacket.

Zur weiteren Erläuterung der Erfindung wird auf ein in den Figuren 1 bis 3 dargestelltes Ausführungsbeispiel der Erfindung verwiesen.To further explain the invention, reference is made to an exemplary embodiment of the invention shown in FIGS. 1 to 3.

  • Fig. 3 is a schematic representation of an impression cylinder with a push-fit tubular steel jacket.

Die Rotationsdruckmaschine 1 besteht aus einem die notwendigen Antriebe und Aggregate enthaltenden Gehäuse 4, auf dessen Vorderseite mittig und parallel zueinander zwei Gegendruckzylinder 2 und 3 angeordnet sind. Um die Gegendruckzylinder 2, 3 sind in zwei parallelen Ebenen je vier Druckwerke 5 und 6 sowie nach jedem Druckwerk eine nicht dargestellte Trocknungseinheit angeordnet.The rotary printing press 1 consists of a housing 4 containing the necessary drives and units, on the front side of which two counter-pressure cylinders 2 and 3 are arranged in the center and parallel to one another. Around the impression cylinders 2, 3, four printing units 5 and 6 are arranged in two parallel planes, as well as a drying unit (not shown) after each printing unit.

Die in Figur 2 dargestellte, am unteren Umfang der Gegendruckzylinder 2, 3 angeordnete Bahnversetzvorrichtung 9 besteht aus zwei am Gehäuse 4 der Rotationsdruckmaschine 1 verschiebbar gelagerten Rundstäben 10, deren Abstand zueinander und deren Winkel zu den Gegendruckzylindern 2, 3 verstellbar sind.The web transfer device 9 shown in FIG. 2 and arranged on the lower circumference of the impression cylinders 2, 3 consists of two round bars 10 which are displaceably mounted on the housing 4 of the rotary printing press 1 and whose spacing from one another and their angle to the impression cylinders 2, 3 are adjustable.

Die in Figur 3 dargestellte Manschette 11 besteht aus einem auf den Gegendruckzylinder 2 aufschiebbaren Stahlrohr , dessen Oberfläche 12 aus einem Gummituch besteht. Eine entsprechende Manschette 11 mit harter Oberfläche befindet sich auf dem Gegendruckzylinder 3. Der Durchmesser beider Gegendruckzylinder 2, 3 ist gleich. Verformungen des mit einem Gummituch bezogenen Stahlrohres 11 während des Druckes, die bis zu 5/100 mm betragen können, machen es jedoch notwendig, den Gummituch-Gegendruckzylinder 2 minimal schneller gegenüber dem Gegendruckzylinder 3 anzutreiben, was durch ein auf den gemeinsamen Antrieb der Gegendruckzylinder 2, 3 wirkendes, nicht dargestelltes Überlagerungsgetriebe erreicht wird.The sleeve 11 shown in FIG. 3 consists of a steel tube which can be pushed onto the impression cylinder 2 and whose surface 12 consists of a rubber blanket. A corresponding sleeve 11 with a hard surface is located on the impression cylinder 3. The diameter of both impression cylinders 2, 3 is the same. Deformations of the steel tube 11 covered with a rubber blanket during printing, which can be up to 5/100 mm, make it necessary to drive the rubber blanket impression cylinder 2 minimally faster than the impression cylinder 3, which is due to the joint drive of the impression cylinder 2 , 3 acting superposition gear, not shown, is reached.

Die zu bedruckende Bahn wird über eine Andrückrolle 7 dem Gegendruckzylinder 2 zugeführt, nach dem Umlauf über die Bahnversetzvorrichtung 9 dem Gegendruckzylinder 3 zugeführt und nach dessen Umlauf über die Rolle 8 zur weiteren Bearbeitung mit nicht dargestellten Vorrichtungen abgeführt.The web to be printed is fed to the impression cylinder 2 via a pressure roller 7, fed to the impression cylinder 3 after circulation via the web transfer device 9 and, after its circulation, discharged via the roller 8 for further processing with devices not shown.
