Description

Die Erfindung betrifft eine Vorrichtung zum Ankuppeln eines entnehmbaren Zylinders einer Rotationsdruckmaschine an ein Antriebsrad gemäß dem Oberbegriff des Anspruches 1.The invention relates to a device for coupling a removable cylinder of a rotary printing press to a drive wheel according to the preamble of claim 1.

Das DE-GM 19 83 546 zeigt einen entnehmbaren Formzylinder, dessen Zapfen mit Lagerungen versehen ist. Diese Lagerungen werden von verdrehbaren Lagerbuchsen mit einem exzentrischen Ausschnitt aufgenommen, die in einem Gestell angeordnet sind. An einem Lagerzapfen ist stirnseitig ein Antriebsrad mittels einer Kupplung drehsteif befestigt.DE-GM 19 83 546 shows a removable forme cylinder, the pin of which is provided with bearings. These bearings are received by rotatable bearing bushes with an eccentric cutout, which are arranged in a frame. A drive wheel is attached to a bearing journal on the end by means of a torsionally rigid coupling.

Das DE GM 18 58 031 stellt eine Vorrichtung zum Ankuppeln eines entnehmbaren Zylinders dar, wobei mittels einer schaltbaren Kupplung und einer Schaltwelle Zylinderzapfen und Antriebsrad verbindbar sind.DE GM 18 58 031 represents a device for coupling a removable cylinder, cylinder pin and drive wheel being connectable by means of a switchable coupling and a selector shaft.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Ankuppeln eines entnehmbaren Zylinders, dessen Zylinderzapfen mit Lagerungen versehen sind, spielfrei an ein Antriebsrad zu schaffen, bei der das Antriebsrad zur Entnahme des Zylinders ortsfest im Gestell verbleibend angeordnet ist.The invention has for its object to provide a device for coupling a removable cylinder, the cylinder pin are provided with bearings, free of play to a drive wheel, in which the drive wheel for removing the cylinder is arranged stationary in the frame.

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.

Für Antriebsräder von Rotationsdruckmaschine werden hochgenaue Zahnräder verwendet. Um präzise Laufeigenschaften zu erhalten, muß die Aufnahme des Antriebsrades genaue Form- und Lagetoleranzen erfüllen. Diese Eigenschaften verschlechtern sich durch ständige Montage und Demontage des Antriebsrades. Somit gewährleistet ein ortsfestes Antriebsrad gute Laufeigenschaften. Zudem ist das Antriebsrad des Zylinders häufig ein Zwischenrad eines Getriebes, so daß auch bei entnommenen Zylinder (z. B. für eine neue Beschichtung) der erfindungsgemäßen Vorrichtung das Getriebe voll funktionsfähig bleibt.High-precision gears are used for drive wheels of rotary printing presses. To be precise In order to maintain running properties, the mounting of the drive wheel must meet exact shape and position tolerances. These properties deteriorate due to constant assembly and disassembly of the drive wheel. Thus, a stationary drive wheel ensures good running properties. In addition, the drive wheel of the cylinder is often an intermediate wheel of a transmission, so that the transmission remains fully functional even when the cylinder is removed (e.g. for a new coating) of the device according to the invention.

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

Ein Zylinder 1 einer Rotationsdruckmaschine ist an seinen Zylinderzapfen 2 mit einer Lagerung 3 versehen. Diese Lagerung 3 ist in einer Lageraufnahme 4 angeordnet, wobei die Lageraufnahme 4 aus zwei voneinander trennbaren Halbschalen 6, 7 besteht und an einer Stirnseite 8 einer mit einer Bohrung 9 versehenen Lagerbuchse 11 befestigt ist. Somit ist der Zylinder 1 bezüglich seiner Drehachse 12 konzentrisch drehbar. Die Lagerbuchse 11 ist in einem Gestell 13 axial unbeweglich angeordnet und kann exzentrisch sowie schwenkbar ausgeführt sein. Dadurch kann ein Abstand zu einem benachbarten, nicht dargestellten Zylinder verändert werden. Die Bohrung 9 der Lagerbuchse 11 weist eine weitere Lagerung 14 konzentrisch bezüglich der Drehachse 12 zur drehbaren, axial festen Aufnahme einer Hohlwelle 16 auf. Diese Hohlwelle 16 ist an ihrem zylinderfernen Ende 17 mit einem Antriebsrad 18 verbunden, während eine Bohrung 19 der Hohlwelle 16 an ihrem zylindernahen Ende 21 mit einer formschlüssigen, in axialer Richtung Versatz ausgleichenden Kupplung 22 versehen ist. Diese Kupplung 22 verbindet die Hohlwelle 16 und eine Schaltwelle 23 drehsteif miteinander. Diese Schaltwelle 23 ist in der Hohlwelle 16 axial verschiebbar und konzentrisch bezüglich der Drehachse 12 gelagert. Ein zylindernahes Ende 24 der Schaltwelle 23 ist mit einer ersten Kupplungshälfte 26 einer formschlüssigen, schaltbaren Kupplung 27 versehen. Diese Kupplung 27 verbindet die Schaltwelle 23 mit dem Zylinder 1, an dessen Zylinderzapfen 2 eine zweite Kupplungshälfte 28 der Kupplung 27 befestigt ist, drehsteif. Ein zylinderfernes Ende 24 der Schaltwelle 23 ist mittels einer Lagerung 31 mit einer in axialer Richtung gestellfesten Stelleinrichtung, z. B. Pneumatikzylinder 32, der eine Stellbewegung in axialer Richtung ausführt, zug- und drucksteif in axialer Richtung verbunden.A cylinder 1 of a rotary printing press is provided with a bearing 3 on its cylinder journal 2. This bearing 3 is arranged in a bearing receptacle 4, the bearing receptacle 4 consisting of two separable half-shells 6, 7 and being fastened to an end face 8 of a bearing bush 11 provided with a bore 9. The cylinder 1 can thus be rotated concentrically with respect to its axis of rotation 12. The bearing bush 11 is axially immovable in a frame 13 and can be made eccentric and pivotable. This allows a distance to an adjacent cylinder, not shown, to be changed. The bore 9 of the bearing bush 11 has a further bearing 14 concentric with respect to the axis of rotation 12 for the rotatable, axially fixed reception of a Hollow shaft 16. This hollow shaft 16 is connected at its end 17 remote from the cylinder to a drive wheel 18, while a bore 19 of the hollow shaft 16 is provided at its end 21 near the cylinder with a form-fitting coupling 22 which compensates for an offset in the axial direction. This clutch 22 connects the hollow shaft 16 and a shift shaft 23 to each other in a torsionally rigid manner. This control shaft 23 is axially displaceable in the hollow shaft 16 and is mounted concentrically with respect to the axis of rotation 12. An end 24 of the selector shaft 23 near the cylinder is provided with a first coupling half 26 of a form-fit, switchable coupling 27. This clutch 27 connects the selector shaft 23 to the cylinder 1, on the cylinder pin 2 of which a second clutch half 28 of the clutch 27 is fastened in a torsionally rigid manner. A remote end 24 of the control shaft 23 is by means of a bearing 31 with an axially fixed actuator, z. B. pneumatic cylinder 32, which performs an actuating movement in the axial direction, tensile and compression-resistant in the axial direction.

Im vorliegenden Beispiel ist die Hohlwelle 16 und Schaltwelle 23 verbindende Kupplung 22 als spielfreie Zahnkupplung ausgeführt. Die Bohrung 19 der Hohlwelle 16 ist mit einer Innenverzahnung 33 ausgestattet, während die Schaltwelle 23 mit zwei Außenverzahnungen 34, 36 versehen ist, wobei eine Scheibe mit der ersten Außenverzahnung 34 in Umfangsrichtung gegenüber der zweiten Außenverzahnung 36
verdrehbar und klemmbar angeordnet ist. Zur Herausnahme des Zahnspiels zwischen Außenverzahnungen 34, 36 und Innenverzahnung 33 wird während der Montage die erste Außenverzahnung 34 gegenüber der zweiten Außenverzahnung 36 verdreht und in dieser Stellung, z. B. mittels Klemmschrauben gesichert.
Anstelle der hier verwendeten Zahnkupplung kann selbstverständlich auch eine Keilwellenverbindung, eine Paßfederverbindungen oder eine Polygonverbindung verwendet werden.In the present example, the clutch 22 connecting the hollow shaft 16 and shift shaft 23 is designed as a backlash-free tooth clutch. The bore 19 of the hollow shaft 16 is provided with an internal toothing 33, while the selector shaft 23 is provided with two external toothings 34, 36, a disk having the first external toothing 34 in the circumferential direction with respect to the second external toothing 36
is arranged rotatable and clampable. To remove the backlash between external teeth 34, 36 and internal teeth 33, the first external teeth 34 are rotated relative to the second external teeth 36 during assembly and in this position, for. B. secured by means of clamping screws.
Instead of the tooth coupling used here, a spline connection, a feather key connection or a polygon connection can of course also be used.

Die Kupplung 27 zwischen Schaltwelle 23 und Zylinderzapfen 2 ist im Ausführungsbeispiel eine Zahnkupplung mit Stirnkerbverzahnung, d. h. die beiden Kupplungshälften 26, 28 sind mit aufeinander angepaßten Stirnkerbverzahnungen versehen, die durch den Pneumatikzylinder 32 mittels der Schaltwelle 23 aufeinander gepreßt bzw. voneinander getrennt werden können.The clutch 27 between the control shaft 23 and the cylinder pin 2 is a toothed coupling with spur toothing in the exemplary embodiment, i. H. the two coupling halves 26, 28 are provided with matched spur toothing, which can be pressed or separated from one another by the pneumatic cylinder 32 by means of the switching shaft 23.

Die Funktionsweise der erfindungsgemäßen Vorrichtung ist folgendermaßen:
Im Betriebszustand ist der Pneumatikzylinder 32 in seine zylindernahe Stellung ausgefahren, wodurch auch die Schaltwelle 23 in ihrer zylindernahen Stellung ist und somit die Kupplung 27 eingekuppelt ist, d. h. die beiden Stirnkerbverzahnungen der Kupplungshälften 26, 28 sind aufeinandergepreßt. Die Kupplung 27 überträgt ein Drehmoment in Umfangsrichtung von der Schaltwelle 26 auf den Zylinderzapfen 2 spielfrei. Mittels der zweiten Kupplung 22 wird von dem Antriebsrad 18 an die Schaltwelle 23 über die Hohlwelle 16 das Drehmoment übertragen. Das Antriebsrad 18 dreht die in der nichtdrehenden Lagerbuchse 11 gelagerte Hohlwelle 16 mit der Drehmoment übertragenden Kupplung 22. Diese überträgt die Drehbewegung an die Schaltwelle 23, welche die Drehbewegung wiederum mittels der Kupplung 27 an den Zylinder 1 weitergibt.
Am zylinderfernen Ende 24 der Schaltwelle 23 wird die drehende Schaltwelle 23 mittels der Lagerung 31 vom nichtdrehenden Pneumatikzylinder 32 bezüglich der Drehbewegung entkoppelt.
Zum Auswechseln des Zylinders 1 wird der Pneumatikzylinder 32 betätigt, wodurch die Schaltwelle 23 in ihre zylinderferne Position gebracht wird. Hierdurch wird die Kupplung 27 entkuppelt, d. h die beiden Kupplungshälften 28, 29 werden voneinander getrennt. Der Schaltweg der Kupplung 27 muß dabei so groß sein, daß die beiden Kupplungshälften 28, 29 senkrecht zur Drehachse 12 aneinander vorbeibewegt werden können.
Die beiden Halbschalen 6, 7 der Lageraufnahme 4 werden voneinander gelöst, so daß der Zylinder 1 mit der daran verbleibenden Lagerung 3 entnommen werden kann. Dabei verbleibt die Kupplungshälfte 28 der Kupplung 27 am Zylinderzapfen 2 des Zylinders 1, weswegen Kupplungshälfte 28 und geöffnete Halbschale 6 so ausgebildet sind, daß die geöffnete Halbschale 6 axial in zylinderabweisender Richtung Raum zur Entnahme der Kupplungshälfte 28 frei gibt.
Der Zylinderzapfen 2 kann aber auch mit einer Bohrung bzw. Senkung zur Aufnahme der Kupplungshälfte 28 innerhalb des Zylinderzapfens 2 versehen sein und so unterhalb der Lagerung 3 liegen.The operation of the device according to the invention is as follows:
In the operating state, the pneumatic cylinder 32 is extended into its position close to the cylinder, as a result of which the selector shaft 23 is in its position close to the cylinder and thus the clutch 27 is engaged, ie the two spur toothings of the clutch halves 26, 28 are pressed together. The clutch 27 transmits a torque in the circumferential direction from the selector shaft 26 the cylinder pin 2 without play. The torque is transmitted from the drive wheel 18 to the selector shaft 23 via the hollow shaft 16 by means of the second clutch 22. The drive wheel 18 rotates the hollow shaft 16, which is mounted in the non-rotating bearing bush 11, with the torque-transmitting clutch 22. This transmits the rotary movement to the selector shaft 23, which in turn transmits the rotary movement to the cylinder 1 by means of the clutch 27.
At the end 24 of the selector shaft 23 remote from the cylinder, the rotating selector shaft 23 is decoupled from the non-rotating pneumatic cylinder 32 with respect to the rotary movement by means of the bearing 31.
To replace the cylinder 1, the pneumatic cylinder 32 is actuated, as a result of which the selector shaft 23 is brought into its position remote from the cylinder. As a result, the clutch 27 is disengaged, d. h the two coupling halves 28, 29 are separated from each other. The switching path of the clutch 27 must be so large that the two coupling halves 28, 29 can be moved past one another perpendicular to the axis of rotation 12.
The two half-shells 6, 7 of the bearing holder 4 are detached from one another so that the cylinder 1 with the bearing 3 remaining thereon can be removed. The coupling half 28 of the coupling 27 remains on the cylinder journal 2 of the cylinder 1, which is why the coupling half 28 and the open half-shell 6 are designed such that the opened half-shell 6 is axial in the cylinder-repellent direction there is space for removing the coupling half 28.
The cylinder journal 2 can, however, also be provided with a bore or countersink for receiving the coupling half 28 within the cylinder journal 2 and thus lie below the bearing 3.
