Description

Die Erfindung betrifft eine Walze für eine Rotationsdruckmaschine gemäß dem Oberbegriff des Anspruches 1.The invention relates to a roller for a Rotary printing machine according to the preamble of Claim 1.

Der Erfindung liegt die Aufgabe zugrunde, eine Walze für eine Rotationsdruckmaschine zu schaffen.The invention has for its object a roller for to create a rotary printing press.

Die FR 25 27 988 und die EP 00 87 730 A1 beschreiben eine Walze mit einer durchgehenden feststehenden Achse. Diese Achse ist an beiden Enden des Ballens mit schwenkbaren Exzenterbuchsen versehen, auf denen der Ballen drehbar gelagert ist.FR 25 27 988 and EP 00 87 730 A1 describe a roller with a continuous fixed axis. This axis is at both ends of the bale provided pivotable eccentric bushings on which the Bale is rotatably mounted.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teiles des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1 solved.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß mittels an der Walze integrierten Einstellvorrichtungen eine Lage einer Drehachse eines Walzenballens bezüglich der Zapfen veränderbar ist. In einfacher Weise erfolgt dies mittels einer Exzenterverstellung.
Somit können Zapfen der Walze bereits außerhalb der Maschine auf einen gewünschten Achsabstand zu einer benachbarten Walze voreingestellt werden.The advantages achievable with the invention consist in particular in that a position of an axis of rotation of a roll barrel with respect to the pins can be changed by means of adjusting devices integrated on the roll. This is done in a simple manner by means of an eccentric adjustment.
Thus, the journal of the roller can already be preset outside the machine to a desired center distance from an adjacent roller.

Die erfindungsgemäße Walze ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.The roller according to the invention is in the drawing shown and is described in more detail below.

Eine Walze 1, insbesondere für ein Farb- oder Feuchtwerk einer Rotationsdruckmaschine, besteht im wesentlichen aus einem Walzenballen 5 und mit Einstellvorrichtungen 4 versehenen Zapfen 6. Der Walzenballen 5 kann beispielsweise ein mit einer Beschichtung 3 versehenes Rohr 2 aufweisen. Die Beschichtung 3 kann beispielsweise aus einem Elastomer, einem Kunststoff, einer Keramik oder einer metallischen Schicht bestehen oder sogar ganz entfallen. Die Zapfen 6 mit den dazugehörigen Einstellvorrichtungen 4 sind an beiden Enden der Walze 1 vorgesehen. Zur Vereinfachung wird im folgenden nur ein Ende der Walze 1 beschrieben.A roller 1, in particular for an inking or dampening unit a rotary printing press, consists essentially from a roll bale 5 and with adjusting devices 4 provided pin 6. The roll barrel 5 can for example one with a coating 3 Have tube 2. The coating 3 can for example made of an elastomer, a plastic, a ceramic or a metallic layer or even entirely omitted. The pin 6 with the associated Adjustment devices 4 are on both Provided ends of the roller 1. To simplify the following only one end of the roller 1 described.

Mittels der Einstellvorrichtung 4 ist eine Mantelfläche 7 , d.h. der Walzenballen 5, der Walze 1 exzentrisch zum Zapfen 6 der Walze 1 einstellbar gelagert.
Der Zapfen 6 dient zur Lagerung der Walze 1 an einer Innenseite 8 eines Seitengestelles 9 der Rotationsdruckmaschine und wird im vorliegenden Beispiel von einer Lagerstelle, beispielsweise einem angedeuteten Lagerhebel 11 aufgenommen. Dazu weist der Lagerhebel 11 einen Bolzen 12 mit einem Ansatz 13 auf. Dieser Ansatz 13 kann in radialer Richtung mit einer gewölbten Fläche, die auf einen Radius des Zapfens 6 angepaßt ist, oder mit einer ebenen Fläche 14 versehen sein. In dieser Fläche 14 ist eine Gewindebohrung 16 eingebracht, in die eine durch eine radiale Bohrung 17 des Zapfens 6 reichende Gewindeschraube 18 eingreift. Somit ist ein erstes Ende des Zapfens 6 mittels der Gewindeschraube 18 nicht drehbar mit dem Lagerhebel 11 verbunden. Nach Lösen dieser Gewindeschraube 18 kann die Walze 1 entnommen werden. Der Walzenballen 5, die Einstellvorrichtungen 4 und die Zapfen 6 bilden eine Einheit und sind gemeinsam aus den Lagerstellen ohne Demontage in einzelne Baugruppen entnehmbar.
Ein zweites Ende des Zapfens 6 ist mit der Einstellvorrichtung 4 verbunden. Diese Einstellvorrichtung ist beispielsweise als Schneckenradgetriebe ausgebildet. Dazu weist das zweite Ende des Zapfens 6 ein konzentrisch zum Zapfen befindliches Schneckenrad 19 auf. Dieses Schneckenrad 19 ist spielfrei drehbar, aber in axialer Richtung durch einen Sicherungsring 21 gesichert, nicht verschiebbar in einer auf das Schneckenrad 19 angepaßten, axialen Bohrung 22 einer Scheibe 23 gelagert. In dieser Scheibe 23 ist tangential, die erste Bohrung 22 schneidend, eine zweite Bohrung 24 vorgesehen. Diese Bohrung 24 nimmt eine mit dem Schneckenrad 19 zusammenwirkende Schnecke 26 auf. Eine Verzahnung 20 der Schnecke 19 greift in eine Verzahnung 25 des Schneckenrades 26 ein. Die Schnecke 26 ist drehbar, aber in Längsrichtung der Bohrung 24 nicht verschiebbar mittels zweier Buchsen 27 und zweier Sicherungsringe 28 in der Bohrung 24 gelagert. An beiden Enden der Schnecke 26 ist jeweils ein Innensechskant 29 für ein Werkzeug zum Einleiten einer Drehbewegung vorgesehen.By means of the adjusting device 4, a lateral surface 7, ie the roller bale 5, of the roller 1 is adjustably mounted eccentrically to the pin 6 of the roller 1.
The pin 6 is used to mount the roller 1 on an inner side 8 of a side frame 9 of the rotary printing press and in the present example is received by a bearing point, for example an indicated bearing lever 11. For this purpose, the bearing lever 11 has a bolt 12 with a shoulder 13. This extension 13 can be provided in the radial direction with a curved surface, which is adapted to a radius of the pin 6, or with a flat surface 14. In this surface 14, a threaded bore 16 is made, into which a threaded screw 18 engages through a radial bore 17 of the pin 6. Thus, a first end of the pin 6 is non-rotatably connected to the bearing lever 11 by means of the threaded screw 18. After loosening this screw 18, the roller 1 can be removed. The roller bale 5, the adjusting devices 4 and the pin 6 form a unit and can be removed together from the bearing points without disassembly into individual assemblies.
A second end of the pin 6 is connected to the adjusting device 4. This setting device is designed, for example, as a worm gear. For this purpose, the second end of the pin 6 has a worm wheel 19 which is concentric with the pin. This worm wheel 19 can be rotated without play, but is secured in the axial direction by a retaining ring 21, and is not displaceably mounted in an axial bore 22 of a disk 23 which is adapted to the worm wheel 19. A second bore 24 is provided tangentially in this disk 23, intersecting the first bore 22. This bore 24 receives a worm 26 cooperating with the worm wheel 19. A toothing 20 of the worm 19 engages in a toothing 25 of the worm wheel 26. The screw 26 is rotatable, but cannot be displaced in the longitudinal direction of the bore 24 by means of two bushes 27 and two locking rings 28 in the bore 24. At both ends of the screw 26, an internal hexagon 29 is provided for a tool for initiating a rotary movement.

An einer der gegenüber der Bohrung 22 liegenden Stirnseite 31 der Scheibe 23 ist ein Bolzen 32 exzentrisch zur Bohrung 22 und damit exzentrisch zum Zapfen 6 starr befestigt. Eine Exzentrizität 33 beträgt beispielsweise 5 mm. Dieser Bolzen 32 ist bezüglich des Rohres 2 der Walze 1 drehbar gelagert. Dazu sind beispielsweise zwei Wälzlager 34 vorgesehen, die mittels Sicherungsringe 36 den Bolzen 32 drehbar in einer fest mit dem Rohr 2 verbundenen Buchse 37 in axialer Richtung unverschiebbar halten.
Die Scheibe 23 kann mit einem Bund 38 versehen sein, auf dem eine Skala angebracht ist. Mit diesem Bund kann ein auf dem Zapfen 6 ortsfest befestigter, als Scheibe ausgebildeter Zeiger 39 vorgesehen sein.On one of the end faces 31 of the disk 23 lying opposite the bore 22, a bolt 32 is rigidly fixed eccentrically to the bore 22 and thus eccentrically to the pin 6. An eccentricity 33 is 5 mm, for example. This pin 32 is rotatably mounted with respect to the tube 2 of the roller 1. For this purpose, two roller bearings 34 are provided, for example, which, by means of retaining rings 36, hold the bolt 32 rotatably in the axial direction in a bush 37 which is fixedly connected to the tube 2.
The disk 23 can be provided with a collar 38 on which a scale is attached. This collar can be used to provide a pointer 39, which is fixed on the pin 6 and is designed as a disk.

Der Zapfen 6 ist somit zum Rohr 2 und damit zum Walzenballen 5 der Walze 1 unter Zwischenschaltung einer Einstellvorrichtung 4 exzentrisch angeordnet und der Walzenballen 2 ist drehbar zum Zapfen 6 gelagert.The pin 6 is thus to the tube 2 and thus Roll bale 5 of the roller 1 with the interposition of a Adjustment device 4 arranged eccentrically and the Roll bale 2 is rotatably mounted to the pin 6.

Die Funktionsweise der erfindungsgemäßen Walze 1 ist folgendermaßen:The operation of the roller 1 according to the invention is as follows:

Zur Veränderung eines Achsabstandes a beispielsweise zwischen der erfindungsgemäßen Walze 1 und einer zweiten Walze 41 wird mittels eines Werkzeuges die Schnecke 26 gedreht. Durch das Zusammenwirken der Schnecke 26 mit dem Schneckenrad 19 des bezüglich des Seitengestells 9 drehfest befestigten Zapfens 6 schwenkt sich die Scheibe 23 zentrisch zum Zapfen 6 und der exzentrisch an der Scheibe 23 befestigte Bolzen 32 ändert seine Lage bezüglich des Zapfens 6. Somit wird eine Lage einer von dem Bolzen 32 festgelegten Drehachse 42 des Walzenballens 5 der Walze 1 bezüglich einer Längsachse 43 des Zapfens 6 und damit der Achsabstand a zwischen den beiden Walzen 1 und 41 verändert.For changing a center distance a, for example between the roller 1 according to the invention and a second Roller 41 becomes worm 26 by means of a tool turned. By the cooperation of the screw 26 with the worm wheel 19 with respect to the side frame 9 rotatably fixed pin 6 pivots the disc 23 centered on the pin 6 and the eccentric on the Washer 23 attached bolt 32 changes its position with respect to the pin 6. Thus, one layer becomes one of the pin 32 fixed axis of rotation 42 of the Roll bale 5 of the roll 1 with respect to a longitudinal axis 43 of the pin 6 and thus the center distance a between the two rollers 1 and 41 changed.

Anstelle der im Ausführungsbeispiel beschriebenen Einstellvorrichtung 4 ist es auch möglich die Scheibe 23 an dem Zapfen 6 anzubringen. Der Bolzen 32 ist dann mit dem Schneckenrad 19 versehen, das dann exzentrisch zum Bolzen 32 angeordnet ist. Bei dieser Ausführung ist dann die Lage der Schnecke 26 fest, da die Scheibe 23 nicht schwenkt.Instead of the one described in the exemplary embodiment Adjustment device 4, it is also possible for the disk 23 to attach to the pin 6. The bolt 32 is then with the worm wheel 19, which is then eccentric to Bolt 32 is arranged. With this version is then the position of the screw 26 fixed, since the disk 23 is not pivots.

Auch ist es möglich den Bolzen 32 nicht im Rohr 2 der Walze 1 zu lagern, sondern den Bolzen 32 mit dem Rohr 2 zu verbinden und eine Lagerung in der Scheibe 23 exzentrisch zum Zapfen 6 anzuordnen.It is also possible not to use the bolt 32 in the tube 2 To store roller 1, but the bolt 32 with the tube 2nd to connect and storage in the disc 23rd to be arranged eccentrically to the pin 6.

Die Einstellvorrichtung 4 kann auch anstelle von Schnecke 26 und Schneckenrad 19 ein Zahnrad und eine damit zusammenwirkende Zahnstange aufweisen. The adjusting device 4 can also be used instead of Worm 26 and worm wheel 19 a gear and one have interacting rack.

Ebenso kann der Zapfen 6 in radialer Richtung mit einer Aussparung versehen sein, in der eine Nuß eingreift. Diese Nuß kann dann mittels einer Gewindespindel tangential zum Zapfen 6 verschiebbar sein und so eine relative Schwenkbewegung zwischen dem Zapfen 6 und dem Bolzen 32 erzeugen. Likewise, the pin 6 in the radial direction with a Be provided recess in which a nut engages. This nut can then by means of a threaded spindle be tangential to the pin 6 and so one relative pivoting movement between the pin 6 and the Generate bolt 32.
