Description

Die Erfindung betrifft einen Druckwerkszylinder einer Rollenrotationsdruckmaschine gemäß dem Oberbegriff des Anspruchs 1 bzw. 7. Insbesondere betrifft die Erfindung Formzylinder und Übertragungszylinder.The invention relates to a printing unit cylinder Web-fed rotary printing press according to the preamble of claim 1 and 7. In particular, the invention relates to forme cylinders and Transfer cylinder.

Bei Rollenrotationsdruckmaschinen ist zur Erzielung einer guten Druckqualität eine konstante Linienkraft zwischen den die Bahn bedruckenden Zylindern erforderlich. Konstante Anstellkräfte werden auch zwischen dem Formzylinder und dem Übertragungszylinder gefordert. Zur Erfüllung dieser Bedingung muß der Achsabstand zwischen den gegeneinander angestellten Zylindern immer gleich sein. Die Zylinder sind hierfür mit Schmitzringen (z. B. DE-OS 2614792) ausgestattet. Bei Druckwerkszylindern, die mit Druckform- oder Übertragungsformhülsen arbeiten, darf sich an der Seite, an der die Hülse abgezogen oder aufgeschoben wird, kein Schmitzring befinden. Um mit derartigen Zylindern dennoch gute Druckergebnisse zu erzielen, werden an die Zylinderlagerungen, insbesondere hinsichtlich Spielfreiheit, große Anforderungen gestellt. Dies gilt auch für die Wandbüchsen, die die Zylinderlager aufnehmen. Üblicherweise sind diese Buchsen jedoch mit Spiel in der Maschinenseitenwand gelagert, da sie z. B. für die Druckan- und -abstellung verdrehbar sein müssen. Auch die Verschiebbarkeit von Wandbüchsen kann gefordert sein.In web-fed rotary printing presses is a good way to achieve Print quality a constant line force between the Cylinder printing cylinders required. Constant hiring forces are also between the forme cylinder and the transfer cylinder required. To meet this condition, the center distance always be the same between the cylinders positioned against each other. For this purpose the cylinders are fitted with bearer rings (e.g. DE-OS 2614792) fitted. For printing unit cylinders with printing form or Transfer form sleeves may work on the side on which the Sleeve is pulled off or pushed on, there is no bearer ring. In order to achieve good printing results with such cylinders achieve the cylinder bearings, in particular with regard to freedom from play, great demands are made this applies also for the wall liners that accommodate the cylinder bearings. Usually, however, these sockets are with play in the Machine side wall stored, since it z. B. for the Druckan- and - Shutdown must be rotatable. The movability of Wall liners may be required.

Der Erfindung liegt die Aufgabe zugrunde, Druckwerkszylinder zu schaffen, mit denen sich eine gute Druckqualität erzielen läßt.The invention has for its object to printing cylinder create with which a good print quality can be achieved.

Diese Aufgabe wird bei gattungsgemäßen Druckwerkszylindern durch die Anwendung der Merkmale des kennzeichnenden Teils des Patentanspruchs 1 oder 7 gelöst. Die Druckwerkszylinder sind spielfrei bzw. spielarm in bzw. an den Seitenwänden des Druckwerks lagerbar. Sie weisen auch keine in der Seitenwand drehbar oder schiebbar zu lagernden Büchsen auf. Diese Büchsen können deshalb spielfrei in der Wand montiert oder sogar in der Wand geklemmt werden. Insgesamt ist hierdurch eine gute Druckqualität erzielbar. Weiterhin verändern bei einem Hülsenwechsel, d. h. bei einer Freilegung der Lagerung des Druckwerkszylinders, die Exzenter ihre Drehlage nicht, d. h. der Druckwerkszylinder behält bei einem Hülsenwechsel unverändert seine Position bei.This task is performed by the generic printing unit cylinders Application of the features of the characterizing part of the claim 1 or 7 solved. The printing unit cylinders are backlash-free or low-backlash can be stored in or on the side walls of the printing unit. You point also none to be rotated or pushed in the side wall Cans on. These bushes can therefore be used in the wall without play mounted or even clamped in the wall. Overall is good print quality can thereby be achieved. Continue to change at a sleeve change, d. H. when the storage of the Printing unit cylinder, the eccentric not its rotational position, d. H. of the Printing unit cylinder remains unchanged when changing sleeves Position at.

Weitere Vorteile und Merkmale ergeben sich aus den Unteransprüchen in Verbindung mit der Beschreibung.Further advantages and features result from the subclaims in connection with the description.

Die Erfindung soll nachfolgend an einigen Ausführungsbeispielen näher erläutert werden. In den zugehörigen Zeichnungen zeigt:

The invention will be explained in more detail below using a few exemplary embodiments. In the accompanying drawings:
Fig. 1
a transfer cylinder,
Fig. 2
a plate cylinder,
Fig. 3
a detail variant of Fig. 1, in sections.

In Fig. 1 ist als Druckwerkszylinder ein Übertragungszylinder 1 gezeigt, der mit seinen Zapfen 2, 3 in Seitenwänden 4, 5 eines Druckwerkes gelagert ist. Die Lagerung in der Seitenwand 5 wird, da nicht zum Gegenstand der Erfindung gehörig, nicht näher beschrieben. Der Zapfen 2 ist mittelbar in der Seitenwand 4 gelagert. Die Seitenwand 4 weist im Bereich des Zapfens 2 eine Öffnung 6 auf, die mit an der Seitenwand 4 angeordneten, quer zum Zapfen 2 verschiebbaren Schiebern 7, 8 verschlossen bzw. freilegbar ist. Eine Ausführung derartiger Schieber ist beispielsweise in der EP 0 277 545 B1 gezeigt. Eine Führung 9 für den Schieber ist angedeutet. In Fig. 1 is a transfer cylinder 1 as a printing unit cylinder shown, the with its pin 2, 3 in side walls 4, 5 one Printing unit is stored. The storage in the side wall 5 is there not part of the subject of the invention, not described in detail. The pin 2 is mounted indirectly in the side wall 4. The Side wall 4 has an opening 6 in the region of the pin 2, which with arranged on the side wall 4, transversely to the pin 2 Slidable slider 7, 8 is closed or exposed. A Execution of such slide is for example in the EP 0 277 545 B1. A guide 9 for the slide is indicated.

Die Schieber 7, 8 nehmen im gezeichneten geschlossenen Zustand die Lagerung 10 des Zapfens 2 auf. Letztere enthält drei ineinanderliegende Ringe 11, 12, 13, die zueinander selbst gelagert sind. Der innere Ring 11 ist auf dem Zapfen 2 angeordnet und mittels eines zweireihigen Zylinderrollenlagers 14 im Ring 12 gelagert.The slider 7, 8 take in the drawn closed state Storage 10 of the pin 2 on. The latter contains three interlocking rings 11, 12, 13 which are mutually supported themselves are. The inner ring 11 is arranged on the pin 2 and by means of a two-row cylindrical roller bearing 14 stored in the ring 12.

Letzterer wiederum ist mittels eines zweireihigen Nadellagers 15 im Ring 13 gelagert. Zur Lagerung der Ringe 11, 12, 13 ineinander können auch anderweitige Wälzlager oder auch Gleitlager zur Anwendung kommen, jedoch eignen sich Wälzlager recht gut zur Realisierung einer gewünschten spielfreien Lagerung. Der Ring 12 ist exzentrisch ausgebildet und vermag so bei seiner Drehung für die Druckan- und -abstellung des Übertragungszylinders 1 dessen Achse zu verschieben. Hierzu weist der Ring 12 eine zum Außenmantel exzentrische Bohrung 16 auf, in der das Zylinderrollenlager 14 aufgenommen wird. Vorteilhaft ist aber noch zwischen das Zylinderrollenlager 14 und den Ring 12 ein exzentrischer Ring 17 gesetzt, der der Grundeinstellung des Übertragungszylinders 1 dient. Im Ausführungsbeispiel ist der Ring 17 mit Preßsitz in der Bohrung 16 gelagert. Zur Verstellung des Rings 17 wird der Preßsitz mit einem nicht dargestellten Hydraulik-Preßverband aufgehoben. Die Verstellung selbst kann beispielsweise mittels eines dem Fachmann geläufigen Gewindespindeltriebes erfolgen. Der Ring 17 kann auch wälzgelagert im Ring 12 angeordnet sein.The latter is in turn by means of a double row needle bearing 15 in Ring 13 stored. For storing the rings 11, 12, 13 one inside the other can also use other roller bearings or plain bearings Are used, however, rolling bearings are quite suitable Realization of a desired play-free storage. The ring 12 is eccentrically trained and can rotate it for the Printing on and off of the transfer cylinder 1 whose axis move. For this purpose, the ring 12 has an outer jacket eccentric bore 16 in which the cylindrical roller bearing 14 is recorded. But it is still advantageous between that Cylindrical roller bearing 14 and the ring 12 an eccentric ring 17th set, which serves the basic setting of the transfer cylinder 1. In the exemplary embodiment, the ring 17 is press-fit in the bore 16 stored. To adjust the ring 17, the press fit with a Hydraulic press fit, not shown, canceled. The Adjustment itself can be done, for example, by a person skilled in the art common threaded spindle drive. The ring 17 can also Rolling in the ring 12 may be arranged.

Der Ring 12 ist als Büchse 18 ausgeführt. Am Boden der Büchse 18 ist eine Stange 19 befestigt, die wiederum drehbar am Zapfen 2 gelagert ist. Sie trägt hierzu an ihrem Ende zwei Rillenkugellager 20, 21, die in einer Bohrung des Zapfens 2 aufgenommen sind. Statt der Rillenkugellager 20, 21 können auch andere Lager eingesetzt werden, die eine Axialkraft aufnehmen können. In der Büchse 18 ist weiterhin die erste Kupplungshälfte 22 einer Schaltkupplung 23 untergebracht. Die Kupplungshälfte 22 ist gegen die Kraft von Federn, beispeilsweise Tellerfedern 24, die sich am Boden der Büchse 18 abstützen, verschiebbar. Sie ist weiterhin mit einer Paßfeder 25 gegen Verdrehen gesichert. Die erste Kupplungshälfte 22 arbeitet mit einer an der Stirnseite des Zapfens 2 befestigten zweiten Kupplungshälfte 26 zusammen. An ihrem Außenmantel trägt die Kupplungshälfte 22 eine Umfangsnut 27, in die eine in der Büchse 18 gelagerte Schaltgabel 28 mit Gleitsteinen 29 eingreift. An der Schaltgabel 28 ist weiterhin ein Hebel 30 angeordnet, der vom Schieber 7 betätigbar ist.The ring 12 is designed as a sleeve 18. At the bottom of the sleeve 18 is a rod 19 attached, which in turn rotatably mounted on the pin 2 is. For this purpose, it carries two deep groove ball bearings 20, 21 at its end. which are received in a bore of the pin 2. Instead of the Deep groove ball bearings 20, 21 can also be used other bearings that can absorb an axial force. In the box 18 is furthermore the first coupling half 22 of a clutch 23 housed. The coupling half 22 is against the force of springs, for example, disc springs 24, which are at the bottom of the sleeve 18th support, movable. It is still with a parallel key 25 secured against twisting. The first coupling half 22 works with a second attached to the end face of the pin 2 Coupling half 26 together. She wears on her outer jacket Coupling half 22 a circumferential groove 27 into which one in the sleeve 18th stored shift fork 28 engages with sliding blocks 29. At the Shift fork 28 is also a lever 30 which is arranged by the Slider 7 is actuated.

Im Betriebszustand des Übertragungszylinders 1 befinden sich die Schieber 7, 8 in der in Fig. 1 gezeichneten Stellung und klemmen dabei die Lagerung 10 spielfrei am Ring 13. Um eine Gummituchhülse 31 vom Übertragungszylinder 1 herunter oder auf diesen durch die Öffnung 6 der Seitenwand 4 schieben zu können, muß der Zapfen 2 im Bereich der Öffnung 6 freigelegt werden. Hierzu werden die Schieber 7, 8 vom Zapfen 2 weggeschoben. Dabei gibt der Schieber 7 den Hebel 30 mitsamt der Schaltgabel 28 frei, wodurch die Tellerfedern 24 die Kupplungshälfte 22 gegen die Kupplungshälfte 26 drücken und damit die Schaltkupplung 23 einrücken. Die Schaltkupplung 23 ist als Reibungskupplung ausgebildet, d. h. die einander zugewandten Stirnseiten der Kupplungshälften 22, 26 tragen Reibbeläge. Die Schaltkupplung könnte beispielsweise auch als Klauen- oder Zahnkupplung ausgeführt werden. Die eingerückte Schaltkupplung 23 bewirkt, daß sich der exzentrisch ausgebildete Ring 12 beim Wechsel der Gummituchhülse 31, d. h. bei freigelegter Lagerung 10 nicht gegenüber dem Übertragungszylinder 1 verdrehen kann. Letzterer wiederum ist durch den Antrieb drehgesichert, mit dem der Zapfen 3, nicht dargestellt, verbunden ist. Weiterhin greift , nicht dargestellt, am Zapfen 3 eine Vorrichtung an, die den Übertragungszylinder 1 bei freigelegter Lagerung 10 fliegend gelagert in der Schwebe hält. Eine nunmehr über den freigelegten Zapfen 2 wechselbare Gummituchhülse 31 ist strichpunktiert dargestellt. Nach erfolgtem Hülsenwechsel werden die Schieber 7, 8 wieder in die gezeichnete Stellung gefahren. Dabei verändert der Übertragungszylinder dank der unveränderten Position des exzentrisch ausgebildeten Ringes 12 seine Lage nicht. Ebenso kann dadurch beim Schließen des Schiebers 8 ein Stellantrieb 32 für den Ring 12 in letzteren eingekuppelt werden. Die Verstellung des Ringes 12 dient, wie weiter oben bereits ausgeführt, der Druckan-und abstellung. Als Stellantrieb 32 kommt dafür im Ausführungsbeispiel ein entsprechend betätigtes Ritzel 33 zur Anwendung, das in ein Zahnsegment 34 der Büchse 18 eingreift. Die Stange 19 sichert auch die Büchse 18 gegen Verschieben. Zur Sicherung des Ringes 13 gegen Verschieben gegenüber dem Ring 12 im freigelegten Zustand des Lagers 10 ist am Ring 13 ein Mitnahmeblech 35 vorgesehen, das in eine Nut 36 des Ringes 12 eingreift. Die Sicherung könnte aber auch anderweitig erfolgen, beispielsweise dadurch, daß das Nadellager 15 mit axialer Festlegung ausgeführt ist.In the operating state of the transfer cylinder 1 are the Slider 7, 8 in the position shown in Fig. 1 and clamp the bearing 10 free of play on the ring 13. Around a rubber blanket sleeve 31 down from the transfer cylinder 1 or on this through the To be able to push opening 6 of the side wall 4, the pin 2 in Area of the opening 6 are exposed. For this, the slider 7, 8 pushed away from the pin 2. The slider 7 gives the lever 30 together with the shift fork 28 free, whereby the plate springs 24 die Press the coupling half 22 against the coupling half 26 and thus engage the clutch 23. The clutch 23 is as Friction clutch formed, d. H. the facing each other End faces of the coupling halves 22, 26 carry friction linings. The Clutch could also be used as a claw or Tooth coupling are carried out. The engaged clutch 23 causes the eccentrically formed ring 12 when changing the blanket sleeve 31, d. H. with exposed storage 10 not can twist relative to the transfer cylinder 1. The latter in turn is secured against rotation by the drive with which the pin 3, not shown, is connected. Still does not shown, on the pin 3 to a device that the Transfer cylinder 1 flying with exposed storage 10 held in suspension. One now over the exposed Pin 2 changeable rubber blanket sleeve 31 is dash-dotted shown. After the sleeve has been changed, the slides 7, 8 moved back to the drawn position. The changes Transfer cylinder thanks to the unchanged position of the eccentric trained ring 12 its location. It can also be used for Closing the slide 8 an actuator 32 for the ring 12 in the latter are engaged. The adjustment of the ring 12 serves as already explained above, the printing on and off. As Actuator 32 comes in the embodiment accordingly actuated pinion 33 for use, which in a toothed segment 34 of the Bush engages 18. The rod 19 also secures the sleeve 18 against Move. To secure the ring 13 against shifting the ring 12 in the exposed state of the bearing 10 is on the ring 13 Driving plate 35 is provided, which in a groove 36 of the ring 12th intervenes. The backup could also be done in another way, for example, in that the needle bearing 15 with axial fixing is executed.

In Fig. 2 ist als Druckwerkszylinder ein Formzylinder 37 gezeigt, der mit seinen Zapfen 38, 39 in Seitenwänden 40, 41 eines Druckwerkes lagert. Dabei wird die Lagerung 42 des Zapfens 38 von Schiebern 43, 44 aufgenommen, die schiebbar an der Seitenwand 40 angeordnet sind und in der gezeichneten Stellung eine Öffnung 62 der Seitenwand 40 verschließen. Die Lagerung 42 enthält zwei ineinander liegende, zueinander axial verschiebbare Ringe 45, 46. Die Ringe 45, 46 werden im Ausführungsbeispiel von einem zweireihigen Zylinderrollenlager 47 verkörpert. Zum Einsatz könnten aber auch anderweitige Wälzlager ohne axiale Festlegung, z. B. Nadellager, oder auch gleitgelagerte Ringe kommen. Von Vorteil ist bei Wälzlagern deren gute Möglichkeit der Einstellung auf Spielfreiheit. Dies erfolgt beispielsweise durch keglige Ausbildung der Bohrung des Ringes 45 sowie des zugehörigen Sitzes des Zapfens 38 und axiale Verstellung des Ringes 45. Der Ring 46 ist fest in einer Büchse 48 angeordnet. Im Boden der Büchse 48 ist zentrisch zum Mantel der Büchse 48 eine Bohrung angeordnet, durch die verschiebbar eine Stange 49 hindurchgeführt ist. Beiderseits der Bodenbohrung der Büchse 18 befinden sich auf der Stange 49 Druckfedern 50, 51, die sich gegen den Boden der Büchse 48 und Anschläge 52, 53 der Stange 49 abstützen. Die Stange trägt weiterhin zwei Rillenkugellager 54, 55, die in einer Bohrung des Zapfens 38 aufgenommen sind. A forme cylinder 37 is shown in FIG. the one with its pin 38, 39 in side walls 40, 41 Printing unit is stored. The bearing 42 of the pin 38 of Sliders 43, 44 added, which are slidable on the side wall 40 are arranged and in the position shown an opening 62 of the Close side wall 40. The bearing 42 contains two one inside the other lying, axially displaceable rings 45, 46. The rings 45, 46 are in the embodiment of a double row Cylindrical roller bearings 47 embodied. But could also be used other rolling bearings without axial fixation, e.g. B. needle bearings, or come with slide bearing rings. It is an advantage at Rolling bearings whose good possibility of adjusting to freedom from play. This is done, for example, by tapering the bore of the ring 45 and the associated seat of the pin 38 and axial Adjustment of the ring 45. The ring 46 is fixed in a sleeve 48 arranged. In the bottom of the sleeve 48 is the center of the jacket Bush 48 arranged a bore through which a Rod 49 is passed. Both sides of the bottom hole of the Bushing 18 are on the rod 49 compression springs 50, 51 which against the bottom of the sleeve 48 and stops 52, 53 of the rod Support 49. The rod also carries two deep groove ball bearings 54, 55, which are received in a bore of the pin 38.

Die Bedingungen für die Rillenkugellager 54, 55 sind die gleichen, wie die der Rillenkugellager 20, 21 in Fig. 1.The conditions for the deep groove ball bearings 54, 55 are the same, like that of the deep groove ball bearing 20, 21 in FIG. 1.

Im Betriebszustand des Formzylinders 37 nehmen die Schieber 43, 44 die in Fig. 2 gezeichnete Stellung ein und klemmen die Büchse 48 spielfrei. Bei einer axialen Verschiebung des Formzylinders 37 verschiebt sich der Ring 45 gegenüber dem Ring 46, ohne daß die Büchse 48 in der Bohrung 56 der Schieber 43, 44 mitgeführt werden muß. Gleichzeitig wird bei dieser Verschiebung je nach Schieberichtung die Stange 49 im Boden der Büchse 48 verschoben und eine der Federn 50, 51 zusammengedrückt. Für einen Wechsel der Gummituchhülse werden die Schieber 43, 44 vom Zapfen 38 und der Lagerung 42 weggeschoben. Sie geben dabei die Büchse 48 frei, die von der zusammengedrückten Feder 50 oder 51 in ihre Nullage zurückgeschoben wird, wobei sich diese Feder 50 oder 51 entspannt. Bei einer neuerlichen Inbetriebnahme des Formzylinders 37 steht nunmehr wieder der volle Verschiebeweg des Ringes 45 gegenüber dem Ring 46 bzw. der volle Verschiebeweg des Formzylinders 37 zur Verfügung. Dieser Vorteil ist gegeben bei einer spielfreien, wahlweise auch geklemmten Lagerung der Büchse 48 in der Seitenwand. Der Wechsel der Druckformhülse 61, die in Fig. 2 strichpunkiert dargestellt ist, erfolgt in an sich bekannter Weise durch Schieben von dem bzw. auf den Formzylinder 37 durch die freigelegte Öffnung 62 der Seitenwand 40 über den freigelegten Zapfen 38. Der an seinen Zapfen 38 freigelegte Formzylinder 37 wird mittels einer nicht dargestellten Vorrichtung an der Seitenwand 41 fliegend gelagert in der Schwebe gehalten.In the operating state of the forme cylinder 37, the slides 43, 44 take the position shown in Fig. 2 and clamp the sleeve 48th free of play. With an axial displacement of the forme cylinder 37 the ring 45 moves relative to the ring 46 without the Bush 48 are carried in the bore 56 of the slide 43, 44 got to. At the same time, this shift depends on Slide direction, the rod 49 in the bottom of the sleeve 48 and moved one of the springs 50, 51 compressed. For a change of Rubber sleeve, the slide 43, 44 of the pin 38 and the Storage 42 pushed away. You release the sleeve 48, the from the compressed spring 50 or 51 to its zero position is pushed back, this spring 50 or 51 relaxes. When the forme cylinder 37 is started up again now again the full displacement of the ring 45 compared to Ring 46 or the full displacement of the forme cylinder 37 Available. This advantage is given with a backlash-free, optionally also clamped mounting of the sleeve 48 in the side wall. The change of the printing form sleeve 61, which is dash-dotted in FIG. 2 is shown, done in a conventional manner by pushing from or onto the forme cylinder 37 through the exposed opening 62 of the side wall 40 over the exposed pin 38. The on his Pin 38 exposed mold cylinder 37 is not by means of a illustrated device on the side wall 41 overhung in suspended.

Das Lösungsprinzip der Fig. 2 (Anspruch 7) ist beispielsweise auch bei dem Druckwerkszylinder gemäß Fig. 1 anwendbar. So kann die Büchse 18' mit Anschlägen 57, 58 versehen sein, an denen sich Druckfedern 59, 60 abstützen, zwischen denen wiederum der Ring 13' plaziert ist (Fig. 3). Beim Hülsenwechsel, d. h. beim Wegfahren des Schiebers 8' bringen die Federn 59, 60 den Ring 13' wieder in eine Nullage zur Büchse 18', aus der er beim Verschieben der Büchse 18', d. h. bei einem Verschieben des Druckwerkzylinders, geraten war. The solution principle of FIG. 2 (claim 7) is also, for example applicable to the printing unit cylinder according to FIG. 1. So it can Bushing 18 'may be provided with stops 57, 58, against which Support compression springs 59, 60, between which in turn the ring 13 ' is placed (Fig. 3). When changing sleeves, d. H. when moving away Slider 8 'bring the springs 59, 60 back into a ring 13' Zero position to the bush 18 ', from which it moves when the bush 18' is moved, d. H. when moving the printing unit cylinder.

Der äußere Ring kann auch mittelbar, z. B. über einen benachbarten Ring, zum Zapfen in eine Nullstellung gebracht werden, beispeilsweise dadurch, daß der äußere Ring ohne Schiebefreiheitsgrad auf dem benachbarten Ring gelagert ist. An letzterm Ring greift dann die Vorrichtung zur Nulleinstellung an.The outer ring can also be indirect, e.g. B. over an adjacent Ring to be put into a zero position for example in that the outer ring without Freedom of sliding is mounted on the adjacent ring. On the latter ring then attacks the device for zeroing.
