Description

Die Erfindung betrifft ein Druckwerk für eine Rollenrotationsdruckmaschine mit mehreren je einen eigenen Antriebsmotor aufweisenden Druckwerkszylindern, die mittels einer Schlittenführung zueinander einstellbar sind.The invention relates to a printing unit for a web-fed rotary printing press with a plurality of printing unit cylinders each having its own drive motor, which can be adjusted to one another by means of a carriage guide.

Aus der deutschen Patentanmeldung 195 34 651.3 ist ein derartiges Druckwerk bekannt, das zwei parallel zu den Stirnflächen der Druckwerkszylinder verlaufende Gestellwände aufweist. Die Druckwerkszylinder sind mit Hülsen unterschiedlichen Durchmessers bestückbar, so dass die Länge des Druckbildes verändert werden kann. Zur Lagerung der Enden eines Druckwerkszylinders ist an den Gestellwänden beiderseits des Druckwerkszylinders je ein Schlitten vorgesehen. Die Schlitten sind mittels mit Druckmittel betriebener Arbeitszylinder verstellbar. Diese Konstruktion weist einen relativ komplizierten Aufbau auf.From the German patent application 195 34 651.3 such a printing unit is known which has two parallel to the end faces of the printing cylinder extending frame walls. The printing cylinder can be equipped with sleeves of different diameters, so that the length of the printed image can be changed. For supporting the ends of a printing cylinder a carriage is provided on the frame walls on both sides of the printing cylinder. The carriages are adjustable by means of working with pressure medium working cylinder. This construction has a relatively complicated structure.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Druckwerk mit einem einfachen, kostengünstigen Aufbau und geringer Breite zu schaffen, bei dem die Übertragung von Schwingungen, die durch einen Druckwerkszylinder angeregt werden, auf andere Druckwerkszylinder über die Mittel zur Einstellung der Schlitten vermieden wird und lange Schlittenführungen für breite Schlitten realisierbar sind.The invention has for its object to provide a generic printing unit with a simple, inexpensive construction and narrow width, in which the transmission of vibrations that are excited by a printing cylinder, on other printing cylinder over the means for adjusting the carriage is avoided and long carriage guides for wide slide can be realized.

Diese Aufgabe wird durch Anwendung der Maßnahmen des Kennzeichens des Anspruchs 1 gelöst.This object is achieved by applying the measures of the characterizing part of claim 1.

Weitere Merkmale und Vorteile ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung.Other features and advantages will become apparent from the dependent claims in conjunction with the description.

Das dargestellte Druckwerk weist eine als Wand oder Fachwerk ausgebildete Tragwand 1 auf, an der gleich ausgebildete Schlitten 2 bis 5 geführt sind. Die gleiche Ausbildung der Schlitten 2 bis 5 bringt eine Herstellungsvereinfachung. Jeder Schlitten 2 bis 5 trägt einen Druckwerkszylinder 6 bis 9 und nimmt einen hier nicht dargestellten Antriebsmotor für seinen Druckwerkszylinder auf. Die Tragwand 1 ist seitlich neben den Stirnseiten 11 der Druckwerkszylinder 6 bis 9 angeordnet. In der parallelen Anmeldung mit dem internen Aktenzeichen PB 04350 sind Antriebsmotoren vorstehend genannter Art dargestellt.The printing unit shown has a trained as a wall or truss supporting wall 1, are guided on the same trained carriages 2 to 5. The same design of the carriage 2 to 5 brings a manufacturing simplification. Each carriage 2 to 5 carries a printing cylinder 6 to 9 and takes a drive motor, not shown here for its printing cylinder on. The support wall 1 is arranged laterally next to the end faces 11 of the printing cylinder 6 to 9. In the parallel application with the internal file number PB 04350 drive motors of the aforementioned type are shown.

Wie insbesondere Figur 2 zeigt, trägt zur Führung des Schlittens 5 eine Wandung 10 der Tragwand 1, die senkrecht zu einer an die Stirnseite 11 des Druckwerkszylinders 9 gelegten, gedachten Ebene verläuft, zwei Führungselemente 12, 13. Die hier schienenförmig ausgebildeten, geraden Führungselemente 12, 13 weisen hier zur Schaffung einer formschlüssigen Schlittenführung einen T-förmigen Querschnitt auf. Das Querhaupt jedes T-förmigen Querschnitts greift in eine entsprechend ausgebildete hinterschnittene Nut 14 am Schlitten 5 ein.As FIG. 2 shows in particular, a wall 10 of the supporting wall 1, which runs perpendicular to an imaginary plane laid on the end face 11 of the printing cylinder 9, carries two guide elements 12, 13 for guiding the carriage 5. The straight guide elements 12, which are rail-shaped here , 13 here have a T-shaped cross-section to create a positive carriage guide. The crosshead of each T-shaped cross-section engages in a correspondingly formed undercut groove 14 on the carriage 5 a.

Parallel zur Wandung 10 ist eine weitere Wandung 15 an der Tragwand 1 vorgesehen, die ebenfalls schienenförmig ausgebildete, gerade Führungselemente 16, 17 T-förmigen Querschnitts trägt. An jeder der beiden Wandungen 10, 15 ist weiterhin für jeden Druckwerkszylinder 6, 8 bzw. 7, 9 eine Gewindespindel 18 bis 21 drehbar, aber axial unverschiebbar gelagert. Die gleich ausgebildeten Führungselemente 12, 13, 16, 17 und die Gewindespindeln 18 bis 21 sind dabei so positioniert, dass die Schlitten 3 und 5 für die Druckwerkszylinder 7 und 9 an der Wandung 11 und die Schlitten 2 und 4 für die Druckwerkszylinder 6 und 8 an der Wandung 15 geführt sind. Die Schlitten miteinander zusammenwirkender, d.h. aufeinander folgender Druckwerkszylinder sind somit jeweils alternierend an den einander gegenüberliegenden Wandungen 10 bzw. 15 angeordnet. In Folge dieser versetzen Anordnung der den Druckwerkszylindern 6 bis 9 zugeordneten Schlitten 2 bis 5 können die Gewindespindeln 18 bis 21 und die Führungselemente, z.B. 12, 13, 16, 17 lang ausgeführt werden. Dies schafft die Möglichkeit, auch die Nuten z.B. 14 mit denen die Schlitten z.B. 5 geführt sind, ebenfalls lang auszubilden. In Folge dieser Ausgestaltung können die Schlitten 2 bis 5 Kräfte und Momente, die im Betrieb auftreten, besser aufnehmen.Parallel to the wall 10, a further wall 15 is provided on the support wall 1, which also carries rail-shaped, straight guide elements 16, 17 carries T-shaped cross-section. On each of the two walls 10, 15 is still a threaded spindle 18 to 21 for each printing cylinder 6, 8 and 7, 9 rotatably mounted, but axially immovable. The identically designed guide elements 12, 13, 16, 17 and the threaded spindles 18 to 21 are positioned so that the carriage 3 and 5 for the printing cylinder 7 and 9 on the wall 11 and the carriage 2 and 4 for the printing cylinder 6 and 8 are guided on the wall 15. The carriages cooperating with each other, i. successive printing cylinder are thus arranged alternately on the opposite walls 10 and 15 respectively. As a result of this offset arrangement of the carriages 2 to 5 associated with the printing couple cylinders 6 to 9, the threaded spindles 18 to 21 and the guide elements, e.g. 12, 13, 16, 17 are executed long. This creates the possibility of even the grooves e.g. 14 with which the carriages e.g. 5 are led, also long form. As a result of this configuration, the carriages 2 to 5 can better absorb forces and moments that occur during operation.

Jede Gewindespindel 18 bis 21 greift in eine in Figur 1 angedeutete, fest in jedem Schlitten 2 bis 5 angeordnete Gewindemutter 18a bis 21a ein. Auf das eine Ende jeder Gewindespindel 18 bis 21 ist fest ein Zahnrad 22 bis 25 aufgesetzt. Jedes Zahnrad steht über ein Vorgelege 26 bis 29 z.B. in Form eines Ketten- oder Riementriebs mit einem weiteren Zahnrad 30 bis 33 in Verbindung, das auf die Abtriebswelle eines an der Tragwand 1 angebrachten Stellmotors 34 bis 37 aufgesetzt ist. Die Stellmotoren sind zweckmäßig als Elektromotoren ausgeführt, die an der Tragwand 1 fest verdrahtet sind. Anstelle eines Kettentriebes könnte, wie erwähnt, auch ein Riementrieb mit Innenverzahnung Verwendung finden.Each threaded spindle 18 to 21 engages in an indicated in Figure 1, fixedly arranged in each carriage 2 to 5 threaded nut 18a to 21a. On the one end of each threaded spindle 18 to 21 is firmly attached to a gear 22 to 25. Each gear is connected via a countershaft 26 to 29, for example in the form of a chain or belt drive with another gear 30 to 33 in connection, which is mounted on the output shaft of a mounted on the support wall 1 servo motor 34 to 37. The actuators are expediently designed as electric motors, which are hardwired to the support wall 1. Instead of a chain drive could, as mentioned, also find a belt drive with internal teeth use.

Figur 1 zeigt die Druckwerkszylinder 6 bis 9 in der Druck-An-Stellung. Zur Druck-Ab-Stellung, in der beispielsweise die Hülsen auf den beiden äußeren, als Formzylinder ausgebildeten Druckwerkszylinder 6 und 9 gewechselt werden können, werden die Druckwerkszylinder 6 und 7 in Figur 1 so nach oben und die Druckwerkszylinder 8 und 9 so nach unten verfahren, dass alle Zylinder voneinander abgehoben sind, wie in Figur 1 mit unterbrochenen Linien angedeutet ist. Durch entsprechende Ansteuerung der Stellmotoren 34 bis 37, die beispielsweise als Schrittmotoren ausgeführt sein können, sind die Druck-An-und-Ab-Stellungen sowie die nachfolgend beschriebenen Positionierungen der Druckwerkszylinder 38 bis 41 bei einem Formatwechsel realisierbar.Figure 1 shows the printing cylinder 6 to 9 in the print-on position. For printing-off position, in which, for example, the sleeves on the two outer, formed as a form cylinder printing cylinders 6 and 9 can be changed, the printing cylinder 6 and 7 in Figure 1 so up and the printing cylinder 8 and 9 so moved down in that all the cylinders are lifted apart from one another, as indicated by broken lines in FIG. By appropriate control of the servomotors 34 to 37, which may be designed, for example, as stepper motors, the pressure on and off positions and the positioning of the printing cylinder 38 to 41 described below can be realized in a format change.

Figur 3 zeigt, dass die Schlitten 2 bis 5 auch mit Druckwerkszylindern 38 bis 41 kleineren Durchmessers bestückt werden können. Die Erfindung bietet daher den weiteren, ganz besonderen Vorteil, dass mit gleich ausgebildeter Tragwand 1 sowie gleich ausgebildeten Schlitten und Schlittenführungen Druckwerke mit Druckwerkszylindern unterschiedlichen Durchmessers ausgeführt werden können.FIG. 3 shows that the carriages 2 to 5 can also be equipped with printing cylinder cylinders 38 to 41 of smaller diameter. The invention therefore offers the further, very particular advantage that printing units with printing cylinder cylinders of different diameters can be designed with the carrier wall 1 of the same design and carriages and slide guides of the same design.

Bei der Ausführung gemäß Figur 4 sind die Führungselemente 53, 54 der beiden Schlitten 42, 43 für die inneren Druckwerkszylinder 44, 45 an einer Wandung 46 und die Führungselemente 55, 56 der beiden Schlitten 47, 48 für die beiden äußeren Druckwerkszylinder 49, 50 an der parallel gegenüberliegenden Wandung 51 einer Tragwand 52 angeordnet. Der Antrieb für die Schlitten 42, 43, 47, 48 ist ebenso wie beim ersten Ausführungsbeispiel ausgeführt und daher nicht mehr dargestellt. Auch bei dieser Ausführungsform besteht die Möglichkeit, in Einstellrichtung lang ausgeführte Schlitten zu verwenden und, wie mit unterbrochenen Linien angedeutet ist, Druckwerkszylinder unterschiedlichen Durchmessers einsetzen zu können. Dabei ist eine Durchmesserveränderung in einem vergleichsweise großen Bereich möglich, ohne die Schlittengröße ändern zu müssen.In the embodiment according to FIG. 4, the guide elements 53, 54 of the two slides 42, 43 for the inner printing cylinder 44, 45 on a wall 46 and the guide elements 55, 56 of the two slides 47, 48 for the two outer printing cylinder 49, 50 at the parallel opposite wall 51 of a support wall 52 is arranged. The drive for the carriage 42, 43, 47, 48 is the same as in the first embodiment and therefore not shown. In this embodiment as well, it is possible to use carriages which are made long in the direction of adjustment and, as indicated by broken lines, to be able to use printing cylinder cylinders of different diameters. In this case, a change in diameter in a relatively large area is possible without having to change the carriage size.

Bei dem in Figur 4 angedeuteten Extremfall müssen die den inneren Druckwerkszylindern 44, 45 zugeordneten Schlitten 42, 43 gegen höhere ausgetauscht werden. Die den äußeren Druckwerkszylindern 49, 50 zugeordneten Schlitten 47, 48 können dagegen beibehalten werden. Auf diese Weise ist sichergestellt, dass den als Formzylinder ausgebildeten äußeren Druckwerkszylindern 49, 50 zugeordnete, bei 57, 58 angedeutete Bebilderungseinrichtungen, deren optische Achse mit der Achse des zugeordneten Formzylinders koplanar sein soll, bezüglich des Abstands von den Führungselementen 55, 56 nicht verstellt werden müssen. Da die Bebilderungseinrichtungen in jedem Fall denselben Abstand von den Führungselementen 55, 56 aufweisen können, können die Bebilderungseinrichtungen 57, 58 stationär angeordnet sein.In the extreme case indicated in FIG. 4, the slides 42, 43 assigned to the inner printing unit cylinders 44, 45 must be exchanged for higher ones. By contrast, the carriages 47, 48 associated with the outer printing unit cylinders 49, 50 can be retained. In this way, it is ensured that the imaging cylinders formed as forme cylinders 49, 50, indicated at 57, 58, whose optical axis should be coplanar with the axis of the associated forme cylinder, are not adjusted with respect to the distance from the guide elements 55, 56 have to. In any case, since the imaging devices may be equidistant from the guide members 55, 56, the imaging devices 57, 58 may be stationary.

Die Bebilderungseinrichtungen können aber auch so verfahrbar sein, dass sie dem jeweils zugeordneten Zylinder entgegenfahren können. Dabei ist zweckmäßig, wenn die Bebilderungseinrichtung bezüglich des zugeordneten Formzylinders 49,50 in dessen Bewegungsrichtung verfahrbar ist. Andererseits ist die Anordnung zweckmäßig so getroffen, dass der Formzylinder 49,50 bezüglich der Bebilderungseinrichtung in dessen Arbeitsrichtung, das heißt Bebilderungsrichtung, verfahrbar ist.However, the imaging devices can also be movable so that they can approach the respective associated cylinder. It is expedient if the imaging device with respect to the associated forme cylinder 49,50 in the direction of movement is movable. On the other hand, the arrangement is suitably made such that the forme cylinder 49, 50 can be moved relative to the imaging device in its working direction, that is to say the direction of the imaging.

Zweckmäßig sind die Bebilderungseinrichtungen 57, 58 hierzu auf den Führungselementen 55, 56 der jeweils zugeordneten Zylinder 49, 50 verfahrbar. Die Führungselemente 55, 56 erstrecken sich hierzu zweckmäßig bis zu den Bebilderungseinrichtungen 57, 58. Es wäre auch denkbar, weitere zum Druck benötigte Zusatz- bzw. Hilfseinrichtungen, wie Farb- und/oder Feuchtwerke ebenso wie oben für die Bebilderungseinrichtungen dargelegt, auf den Führungselementen 55, 56 verfahrbar und somit an den zugeordneten Zylinder heranfahrbar anzuordnen. Selbstverständlich sind den verfahrbaren Hilfs- bzw. Zusatzeinrichtungen geeignete Antriebsmittel in Form von z.B. Stellmotoren zugeordnet.Suitably, the imaging devices 57, 58 for this purpose on the guide elements 55, 56 of the respective associated cylinder 49, 50 movable. The guide elements 55, 56 expediently extend to the imaging devices 57, 58. It would also be conceivable to use additional devices or auxiliary devices required for printing, such as inking and / or dampening units, as explained above for the imaging devices, on the guide elements 55, 56 movable and thus arranged to be approached to the associated cylinder. Of course, the traversable auxiliary means are suitable drive means in the form of e.g. Assigned servomotors.

Dank der Bewegbarkeit der Formzylinder 49, 50 auf die Hilfseinrichtungen, wie hier die Bebilderungseinrichtungen 57, 58, zu und letzterer auf den zugeordneten Formzylinder 49,50 zu, ist eine sehr hohe Format-Variabilität gewährleistet. Bei Bebilderungseinrichtungen 57, 58, wie gezeichnet, erfolgt die gegenseitige Verstellung von Zylinder und Bebilderungseinrichtung in Bebilderungsrichtung, d.h. in Richtung der optischen Achse der Bebilderungseinrichtung. Trotz hoher Format-Variabilität wird jeweils nur ein Führungselement benötigt, auf dem sowohl der Formzylinder 49, 50 als auch die zugeordnete Zusatzeinrichtung verfahrbar sind.Thanks to the mobility of the form cylinder 49, 50 on the auxiliary equipment, such as here the imaging devices 57, 58, and the latter on the associated forme cylinder 49,50, a very high format variability is ensured. In the case of imaging devices 57, 58, as shown, the mutual adjustment of the cylinder and the imaging device takes place in the direction of imaging, i. in the direction of the optical axis of the imaging device. Despite high format variability only one guide element is required in each case, on which both the forme cylinder 49, 50 and the associated additional device are movable.

Bei den oben beschriebenen Ausführungsbeispielen sind die Druckwerkszylinder fliegend gelagert. Sie können aber auch an beiden Enden in je einem Schlitten gelagert sein. Dann ist eine zweite Tragwand vorzusehen, die analog zur Tragwand 1 mit Führungselementen und Gewindespindeln versehen ist. Diese Tragwand kann dann zum Hülsen- oder Zylinderwechsel abklappbar oder in Längsrichtung der Zylinder verfahrbar ausgebildet sein, wie es in der parallelen Anmeldung mit dem internen Aktenzeichen PB 04350 beschrieben ist.In the embodiments described above, the printing unit cylinders are mounted on the fly. But you can also be stored at both ends in a carriage. Then, a second support wall is provided, which is provided analogously to the support wall 1 with guide elements and threaded spindles. This support wall can then be hinged to the sleeve or cylinder change or designed to be movable in the longitudinal direction of the cylinder, as described in the parallel application with the internal file number PB 04350.

Bei den oben beschriebenen Beispielen ist die Bedruckstoffbahn, wie in Figur 4 bei 59 angedeutet ist, etwa horizontal geführt. Die erfindungsgemäßen Druckwerke sind aber durch entsprechend gedrehte Anordnung der Führungselemente um etwa 90° auch für einen vertikalen Lauf der Bahn 59 konzipierbar.In the examples described above, the printing material web, as indicated at 59 in FIG. 4, is guided approximately horizontally. The However, printing units according to the invention are conceivable by appropriately rotated arrangement of the guide elements by about 90 ° for a vertical run of the web 59.
