Abstract

A cylinder unit is provided for a web-fed printing press. The unit includes first and second cylinders which form printing gaps with a common first counterpressure cylinder. Third and fourth cylinders are provided which form printing gaps with a common second counterpressure cylinder. The four cylinders and the two counterpressure cylinders are cylinders of a single H-shaped cylinder bridge. The second and third cylinders are spaced from one another at such a distance that a web can run in between these two cylinders in their printing-on positions at the respective counterpressure cylinders and can run out after wrapping around the two counterpressure cylinders. The first and fourth cylinders are spaced so close to one another that they can be reversed from a printing-on position against their respective counterpressure cylinder into printing-on position in relation to one another.

Description

Die Erfindung betrifft eine Zylindereinheit für eine Rollenrotationsdruckmaschine.The invention relates to a cylinder unit for a web-fed rotary printing press.

Die Erfindung hat es sich zur Aufgabe gemacht. die Flexibilität einer Zylindereinheit in Bezug auf die Bildung von Druckspalten für eine zu bedruckende Bahn zu erhöhen.The invention has set itself the task. the flexibility of a cylinder unit in Increase in relation to the formation of printing gaps for a web to be printed.

Diese Aufgabe wird durch den Gegenstand von Schutzanspruch 1 gelöst.This object is achieved by the subject matter of protection claim 1.

Die Erfindung geht von einer Zylindereinheit aus, deren Zylinder eine H-förmige Zylinderbrücke mit vier Farbe auf eine Bahn übertragenden Zylindern und zwei zentralen Gegendruckzylindern für diese vier Farbübertragungszylinder aus. Je zwei der vier Farbübertragungszylinder der H-Zylinderbrücke sind je in eine Druck-An-Stellung zu einem gemeinsamen Gegendruckzylinder schwenkbar.The invention is based on a cylinder unit whose cylinder is H-shaped Cylinder bridge with four colors on a web transferring cylinders and two central ones Impression cylinders for these four ink transfer cylinders. Two of the four Ink transfer cylinders of the H-cylinder bridge are each in a print-on position to one common impression cylinder swiveling.

Nach der Erfindung sind zwei der vier Farbübertragungszylinder aus einer Druck-An-Stellung zu ihrem jeweiligen zentralen Gegendruckzylinder in eine Druck-An-Stellung zueinander umsteuerbar. Die beiden anderen Farbübertragungszylinder sind soweit voneinander beabstandet, dass zwischen ihnen eine zu bedruckende Bahn ungehindert einlaufen und nach Umschlingen beider Gegendruckzylinder wieder auslaufen kann. Durch diese unsymmetrische Anordnung der vier Farbübertragungszylinder zu den beiden zentralen Gegendruckzylindern der H-Brücke wird ein Höchstmaß an Flexibilität hinsichtlich der Bildung von Druckstellen erzielt.According to the invention, two of the four ink transfer cylinders are from a print-on position to their respective central impression cylinder in a print-on position reversible to each other. The other two ink transfer cylinders are ready spaced from each other that between them a web to be printed is unimpeded run in and run out again after wrapping both impression cylinders. By this asymmetrical arrangement of the four ink transfer cylinders to the two central ones Counter pressure cylinders of the H-bridge will offer maximum flexibility in terms of Formation of pressure points achieved.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels beschrieben.The invention is described below using a preferred exemplary embodiment described.

Die Figur zeigt eine H-förmige Zylindereinheit einer Rollenrotationsdruckmaschine. Die Zylindereinheit weist vier Zylinder 1, 2, 3 und 4 auf, die Farbe auf eine Bahn B1 und/oder B2 übertragen. Diese vier Farbübertragungszylinder 1 bis 4 bilden je einen Druckspalt und insgesamt vier Druckspalte mit zwei zentralen Gegendruckzylindern 5 und 6. Im Ausführungsbeispiel handelt es sich bei den vier Farbübertragungszylindern 1 bis 4 um Gummituchzylinder, während die zentralen Gegendruckzylinder 5 und 6 als Stahlzylinder ausgebildet sind. Jedem der vier Farbübertragungszylinder 1 bis 4 ist jeweils ein Plattenzylinder 8 in an sich bekannter Weise zugeordnet. Die dargestellte Zylindereinheit wird im allgemeinen als 10-Zylindereinheit bezeichnet.The figure shows an H-shaped cylinder unit of a web-fed rotary printing press. The cylinder unit has four cylinders 1, 2, 3 and 4, which transfer color to a web B 1 and / or B 2 . These four ink transfer cylinders 1 to 4 each form a printing nip and a total of four printing nips with two central impression cylinders 5 and 6. In the exemplary embodiment, the four ink transfer cylinders 1 to 4 are blanket cylinders, while the central impression cylinders 5 and 6 are designed as steel cylinders. A plate cylinder 8 is assigned to each of the four ink transfer cylinders 1 to 4 in a manner known per se. The cylinder unit shown is generally referred to as a 10-cylinder unit.

Die Anordnung der Farbübertragungszylinder 1 bis 4 sowie deren Plattenzylinder 8 ist symmetrisch zu einer gedachten Mittelsenkrechten zur Verbindungslinie der Drehachsen der beiden zentralen Gegendruckzylinder 5 und 6. Die Anordnung der Farbübertragungszylinder 1 bis 4 ist jedoch nicht symmetrisch bezüglich dieser Verbindungslinie zwischen den Drehachsen der beiden Gegendruckzylinder 5 und 6. Die beiden Farbübertragungszylinder 2 und 3, die zu einer Seite dieser Verbindungslinie angeordnet sind, weisen zueinander einen größeren Abstand auf als die beiden zur anderen Seite dieser Verbindungslinie angeordneten Farbübertragungszylinder 1 und 4.The arrangement of the ink transfer cylinders 1 to 4 and their plate cylinder 8 is symmetrical to an imaginary perpendicular to the connecting line of the axes of rotation of the two central impression cylinders 5 and 6. The arrangement of the ink transfer cylinders 1 to 4 is however not symmetrical with respect to this connecting line between the Axes of rotation of the two impression cylinders 5 and 6. The two ink transfer cylinders 2 and 3, which are arranged on one side of this connecting line, face each other a greater distance than the two to the other side of this connecting line arranged ink transfer cylinders 1 and 4.

Der lichte Abstand zwischen den beiden Farbübertragungszylindern 2 und 3 ist so groß, dass eine Bahn B1 durch den Raum zwischen diesen beiden Zylindern geführt. in einem ersten Druckspalt zwischen dem Farbübertragungszylinder 2 und dem Gegendruckzylinder 5 bedruckt, den Gegendruckzylinder 5 und den Gegendruckzylinder 6 hintereinander umschlingend weitergeführt und in einem weiteren Druckspalt, der durch den Farbübertragungszylinder 3 und dessen Gegendruckzylinder 6 gebildet wird, nochmals bedruckt und zwischen den Farbübertragungszylindern 2 und 3 hindurch ungehindert, im Ausführungsbeispiel parallel zum Bahneinlauf, auslaufen kann. Im Zwischenraum zwischen den beiden Farbübertragungszylindern 2 und 3 sind zwei Umlenkrollen 11 und 12 angeordnet, um die die Bahn B1 vor und nach dem Umschlingen der beiden Gegendruckzylinder 5 und 6 umgelenkt wird.The clear distance between the two ink transfer cylinders 2 and 3 is so large that a web B 1 runs through the space between these two cylinders. printed in a first printing nip between the ink transfer cylinder 2 and the impression cylinder 5, looping the impression cylinder 5 and the impression cylinder 6 one after the other and printed again in a further printing gap, which is formed by the ink transfer cylinder 3 and its impression cylinder 6, and between the ink transfer cylinders 2 and 3 can run through unhindered, in the exemplary embodiment parallel to the web inlet. In the space between the two ink transfer cylinders 2 and 3, two deflection rollers 11 and 12 are arranged, around which the web B 1 is deflected before and after the two impression cylinders 5 and 6 are looped around.

Die im Ausführungsbeispiel oberen Farbübertragungszylinder 1 und 4 befinden sich ebenfalls je in einer Druck-An-Stellung gegen ihren Gegendruckzylinder 5 bzw. 6. Die Bahn B1 wird in der gezeigten Zylinderstellung einseitig vierfach bedruckt. Vorteil der erfindungsgemäßen Zylinderanordnung in dieser Stellung der Farbübertragungszylinder 1 bis 4 ist, dass keiner der vier druckenden Zylinder 1 bis 4 von der Bahn B1 umschlungen wird. Die Bahn B1 umschlingt die beiden Gegendruckzylinder 5 und 6 und verläuft tangential zu jedem der vier Farbübertragungszylinder 1 bis 4. Jeder dieser vier Farbübertragungszylinder 1 bis 4 kann daher selbst bei laufender Bahn B1, d.h. während einer Produktion, im Ausführungsbeispiel einer 4,0-Produktion, durch Abschwenken von seinem jeweiligen Gegendruckzylinder 5 bzw. 6 aus der Produktion genommen werden. Im umgekehrten Fall gilt dies auch für ein Zuschwenken.The upper ink transfer cylinders 1 and 4 in the exemplary embodiment are also each in a print-on position against their impression cylinder 5 or 6. The web B 1 is four-sided printed in the cylinder position shown. The advantage of the cylinder arrangement according to the invention in this position of the ink transfer cylinders 1 to 4 is that none of the four printing cylinders 1 to 4 is wrapped in the web B 1 . The web B 1 wraps around the two impression cylinders 5 and 6 and extends tangentially to each of the four ink transfer cylinders 1 to 4. Each of these four ink transfer cylinders 1 to 4 can therefore even with web B 1 running, ie during production, in the exemplary embodiment a 4.0 -Production, can be taken out of production by swiveling its respective impression cylinder 5 or 6. In the opposite case, this also applies to swiveling.

Während die im Ausführungsbeispiel beiden unteren Farbübertragungszylinder 2 und 3 durch Abschwenken produktionslos werden, sind die beiden im Ausführungsbeispiel oberen Farbübertragungszylinder 1 und 4 jedoch so eng zueinander beabstandet, dass sie aus ihrer Druck-An-Stellung gegen ihren jeweiligen Gegendruckzylindern 5 bzw. 6 in eine Druck-An-Stellung zueinander durch Abschwenken von den Gegendruckzylinder 5 und 6 und Zuschwenken aufeinander zu umsteuerbar sind. Die letztgenannte, alternative Druck-An-Stellung der beiden Farbübertragungszylinder 1 und 4 ist in der Figur in gestrichelten Linien dargestellt. In dieser alternativen Druck-An-Stellung sind die beiden Farbübertragungszylinder mit 1' und 4' bezeichnet. In der Stellung 1'/4' kann beispielsweise. wie in der Figur dargestellt, eine zweite B2 durch die beiden Farbübertragungszylinder 1 und 4 beidseitig je einfarbig bedruckt werden. In der Figur angedeutet ist somit eine zweibahnige Produktion. While the two lower ink transfer cylinders 2 and 3 in the exemplary embodiment become production-free by swiveling, the two upper ink transfer cylinders 1 and 4 in the exemplary embodiment are spaced so closely to one another that they move from their print-on position against their respective counter-pressure cylinders 5 and 6 into one Pressure-on position to one another can be reversed by swiveling counter-pressure cylinders 5 and 6 and swiveling towards one another. The latter, alternative print-on position of the two ink transfer cylinders 1 and 4 is shown in the figure in dashed lines. In this alternative print-on position, the two ink transfer cylinders are designated 1 'and 4'. In position 1 '/ 4', for example. As shown in the figure, a second B 2 can be printed on both sides in one color by the two ink transfer cylinders 1 and 4. A two-lane production is thus indicated in the figure.

Dabei wird die Bahn B1 durch die beiden Farbübertragungszylinder 2 und 3 hintereinander einseitig zweifarbig bedruckt, während die Bahn B2 durch die beiden Farbübertragungszylinder 1 und 4 beidseitig, je einfarbig bedruckt wird.The web B 1 is printed in two colors on one side by the two ink transfer cylinders 2 and 3, while the web B 2 is printed on both sides by the two ink transfer cylinders 1 and 4, in each case in one color.

Die erfindungsgemäße Anordnung ist nicht nur besonders flexibel im Hinblick auf die realisierbaren alternativen Produktionsmöglichkeiten, sondern baut zudem besonders platzsparend. Gegenüber einer H-Brücke mit zwei zentralen Gegendruckzylindern, die symmetrisch sowohl bezüglich der Verbindungslinie zwischen den Drehachsen der beiden Gegendruckzylinder 5 und 6 als auch bezüglich der Mittelsenkrechten zu dieser Verbindungslinie ist, wird durch die erfindungsgemäß nicht symmetrische Anordnung Bauhöhe eingespart durch die flachbauende obere V-Brücke der beiden Farbübertragungszylinder 1 und 4 sowie deren Plattenzylinder 8. Wegen des engeren Abstands der beiden oberen Farbübertragungszylinder baut die obere V-Brücke bei gleicher Baubreite flacher als die untere N-Brücke der 10-Zylindereinheit. Gleichzeitig werden die Vorteile der umschlingungsfreien Bahnführung - umschlingungsfrei auch in Bezug auf die beiden enger beabstandeten Farbübertragungszylinder - erhalten. Durch die umschlingungsfreie Bahnführung wird nämlich das Zu- und Abschwenken von Farbübertragungszylindern bei laufender Produktion vereinfacht, da das Zu- und Abschwenken von Zylindern nicht zu Bahnschwingungen führt, die in Bezug auf die Produktionsqualität nicht tolerierbar wären. Insbesondere wird durch das Zu- und Abschwenken, d.h. durch das Umbilden von Druckspalten bzw. Druckstellen der Weg der Bahn nicht verändert.The arrangement according to the invention is not only particularly flexible with regard to the feasible alternative production options, but also builds special space-saving. Opposite an H-bridge with two central impression cylinders, the symmetrical both with respect to the connecting line between the axes of rotation of the two Impression cylinders 5 and 6 as well as with respect to the perpendicular to this Connection line is due to the non-symmetrical arrangement according to the invention Construction height saved by the flat top V-bridge of the two ink transfer cylinders 1 and 4 and their plate cylinder 8. Because of the closer distance between the two upper ink transfer cylinder builds the upper V-bridge flatter than the same width the lower N-bridge of the 10-cylinder unit. At the same time, the advantages of wrap-free web guide - wrap-free also in relation to the two tighter spaced ink transfer cylinder - obtained. Because of the loop-free Web guiding is the pivoting in and out of ink transfer cylinders ongoing production is simplified because the swiveling in and out of cylinders does not close Path vibrations that would be intolerable in terms of production quality. In particular, by swiveling in and out, i.e. by remodeling Pressure gaps or pressure points did not change the path of the web.

Ein bevorzugtes Antriebskonzept ist in der Figur ebenfalls dargestellt. Zwischen den Farbübertragungszylindern 1 bis 4 und dem Gegendruckzylinder 5 und 6 untereinander besteht keine formschlüssige Antriebsverbindung. Die Zylinder 1 bis 6 stehen allenfalls über die Bahn bzw. über Schmitzringe in Reibverbindung. Jeder der Zylinder 1 bis 6 wird durch einen eigenen Motor 7 angetrieben. Die Kraftübertragung erfolgt von jedem der Motoren 7 über jeweils ein Getriebe 9, vorzugsweise ein Zahnriemen, unmittelbar auf die Zylinder 1 bis 6. Die nachgeordneten Plattenzylinder 8 sind formschlüssig mit ihren jeweiligen Farbübertragungszylindern 1 bis 4 zum damit gemeinsamen Antrieb gekoppelt. Alternativ könnten die Motoren 7 statt der Farbübertragungszylinder 1 bis 4 jeweils deren zugeordneten Plattenzylinder 8 ebenfalls unmittelbar über ein Getriebe, vorzugsweise ebenfalls ein Zahnriemen antreiben, und die Farbübertragungszylinder 1 bis 4 würden in diesem Fall im Schlepp je ihres Plattenzylinders 8 mitangetrieben werden. Ebenso könnten auch die beiden Gegendruckzylinder 5 und 6 antriebsseitig je mit einem der Farbübertragungszylinder zum damit gemeinsamen Antrieb formschlüssig gekoppelt sein. Bevorzugt wird jedoch wegen des erleichterten Zu- und Abschwenkens der Farbübertragungszylinder die in der Figur gezeigte Konfiguration mit den eigenangetriebenen Gegendruckzylindern 5 und 6.A preferred drive concept is also shown in the figure. Between Ink transfer cylinders 1 to 4 and the impression cylinders 5 and 6 with each other there is no positive drive connection. The cylinders 1 to 6 protrude at most the web or via bearer rings in friction connection. Each of cylinders 1 through 6 is through own motor 7 driven. The power transmission takes place from each of the motors 7 via a gear 9, preferably a toothed belt, directly to the cylinder 1 to 6. The downstream plate cylinders 8 are form-fitting with their respective ink transfer cylinders 1 to 4 coupled to the common drive. Alternatively could the motors 7 instead of the ink transfer cylinders 1 to 4 each assigned to them Plate cylinder 8 also directly via a gear, preferably also a Drive toothed belt, and the ink transfer cylinders 1 to 4 would in this case Towing each of their plate cylinder 8 are driven. The two could as well Impression cylinders 5 and 6 on the drive side each with one of the ink transfer cylinders thus joint drive can be positively coupled. However, is preferred because of facilitated pivoting in and out of the ink transfer cylinder shown in the figure Configuration with the self-propelled impression cylinders 5 and 6.
