Abstract

The invention relates to a bearing for a printing unit cylinder of a web-fed rotary printing machine, having an exchangeable jacket (2) which, for this purpose, can be pulled axially from the cylinder (1). An auxiliary device which supports the cylinder on one side during the jacket change is intended to retain said cylinder all-around, but not contact it during the printing operation. For this purpose, a slide (10, 21), which is arranged displaceably in the frame, supports the journal (3, 41) and partially surrounds it in a recess (15), can be engaged in each case on the journal (3, 41) by means of an eccentric (18, 23, 38) outside and/or inside the machine side wall (5) bearing the journal (3, 41) of the cylinder (1). <IMAGE>

Description

Die Erfindung betrifft eine Lagerung für einen Druckwerkzylinder einer Rollenrotationsdruckmaschine gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a bearing for a printing couple cylinder of a web-fed rotary printing press according to the preamble of patent claim 1.

Eine derartige Lagerung eines Zylinders wird in der DE-OS 27 24 653 vorgestellt. Danach wird für den Wechsel des Mantels des Zylinders letzterer einseitig gehalten, indem am aus der Maschinenseitenwand herausragenden Zapfen ein Arbeitszylinder angreift. Auf dem Zapfen ist hierfür, auf einem Wälzlager gelagert, ein Gelenkkopf angeordnet, an dem der Arbeitszylinder angelenkt ist.Such storage of a cylinder is presented in DE-OS 27 24 653. Then the cylinder is held on one side for changing the jacket of the cylinder by a working cylinder engaging on the pin protruding from the side wall of the machine. For this purpose, a joint head, on which the working cylinder is articulated, is arranged on the journal and is mounted on a roller bearing.

Bei dieser Vorrichtung ist von Nachteil, daß der Arbeitszylinder auch im Betrieb des Zylinders mit dessen Zapfen in Verbindung steht. Rundlauffehler des Zapfens verursachen dabei ständige Reibung zwischen der Kolbenstange und der Stopfbuchse des Arbeitszylinders, was zu Ausfällen des Arbeitszylinders und Stillstandszeiten der Druckmaschine führt. Weiterhin wird der Druckwerkzylinder nur in der Zugrichtung des Arbeitszylinders fixiert, wodurch der Mantel nur erschwert und unter der Gefahr seiner Beschädigung durch die Öffnung der Seitenwand geführt werden kann. Außerdem legt die einseitige Fixierung des Druckwerkzylinders die Lagerung seines Zapfens in einem Pendellager nahe.A disadvantage of this device is that the working cylinder is connected to its journal even during operation of the cylinder. The runout of the pin causes constant friction between the piston rod and the stuffing box of the working cylinder, which leads to failures of the working cylinder and downtimes of the printing press. Furthermore, the printing unit cylinder is only fixed in the pulling direction of the working cylinder, as a result of which the jacket can only be guided through the opening in the side wall with difficulty and with the risk of damage. In addition, the one-sided fixation of the printing unit cylinder suggests the storage of its journal in a self-aligning bearing.

Der Erfindung liegt die Aufgabe zugrunde, bei einer Lagerung für einen Druckwerkzylinder einer Rollenrotationsdruckmaschine mit einer Hilfsvorrichtung zum einseitigen Halten des Zylinders, der einen auswechselbaren, hierzu seitlich durch eine Öffnung einer Maschinenseitenwand schiebbaren Mantel trägt, die Hilfsvorrichtung so zu gestalten, daß sie den Druckwerkzylinder umfassend arretiert und im Druckbetrieb nicht berührt.The invention is based on the object, in a bearing for a printing unit cylinder of a web-fed rotary printing press with an auxiliary device for holding the cylinder on one side, which carries an exchangeable jacket which can be pushed laterally through an opening in a machine side wall, to design the auxiliary device such that it comprises the printing unit cylinder locked and not touched during printing.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß an den in der anderen Maschinenseitenwand gelagerten Zapfen des Zylinders außerhalb und/oder innerhalb dieser Maschinenseitenwand je ein im Gestell verschiebbar gelagerter, den Zapfen stützender und in einer Ausnehmung teilweise umfassender Schlitten mittels eines Exzenters anstellbar ist. Mit dem bzw. den Schlitten wird der Zylinder zuverlässig allseitig gehalten. Dadurch sind die Voraussetzungen für einen schonenden Wechsel des Zylindermantels und die Vermeidung von Kantenpressung des Lagers des Zylinders gegeben. Letzteres ermöglicht den Verzicht auf ein Pendellager. Bei der Anordnung von Schlitten beiderseits der Maschinenseitenwand wird außerdem die Kraft auf das Lager beim Wechseln des Zylindermantels niedriger gehalten. Die Hilfsvorrichtung steht im Druckbetrieb nicht mit dem Druckwerkzylinder in Kontakt und ist somit keinem erhöhten, Maschinenstillstände verursachenden Verschleiß unterworfen.According to the invention the object is achieved in that on the journals of the cylinder mounted in the other side wall of the machine outside and / or within this side wall of the machine one slidably mounted in the frame, supporting the tenon and partially encompassing a carriage by means of an eccentric. The cylinder (s) hold the cylinder reliably on all sides. This provides the prerequisites for a gentle change of the cylinder jacket and the avoidance of edge pressure on the bearing of the cylinder. The latter makes it possible to dispense with a self-aligning bearing. With the arrangement of slides on both sides of the machine side wall, the force on the bearing is also at Changing the cylinder jacket kept lower. The auxiliary device is not in contact with the printing unit cylinder during printing operation and is therefore not subject to increased wear which causes machine downtimes.

Der Schlitten ist vorteilhaft verschiebbar, wenn er erfindungsgemäß quer zu seiner Bewegungsrichtung ein Langloch aufweist, in das der exzentrische Zapfen eines Exzenterbolzens eingreift, oder von einer sich im Gestell abstützenden Feder beaufschlagt wird und sich kraftschlüssig auf einem Exzenterbolzen abstützt.The slide is advantageously displaceable if, according to the invention, it has an elongated hole transverse to its direction of movement, into which the eccentric pin of an eccentric pin engages, or is acted upon by a spring which is supported in the frame and is non-positively supported on an eccentric pin.

Die Exzenterverstellung ist vorteilhaft ausführbar, wenn erfindungsgemäß an dem Exzenter ein Arbeitszylinder angreift.The eccentric adjustment can advantageously be carried out if, according to the invention, a working cylinder acts on the eccentric.

Figur 1 zeigt einen Zylinder 1, beispielsweise einen Form- oder Übertragungszylinder einer Offset-Rotationsdruckmaschine, der einen auswechselbaren Mantel 2 trägt. Die Zapfen 3; 4 des Zylinders 1 sind in den Maschinenseitenwänden 5; 6 gelagert. Dabei wird das Lager des Zapfens 4 in einem nicht dargestellten Wandstück beherbergt, das entfernbar ist und so eine Öffnung 7 in der Maschinenseitenwand 6 freigibt. Der Zapfen 3 wird in einem Lager 8 aufgenommen. Er ragt aus der Maschinenseitenwand 5 heraus und trägt ein Zahnrad 9. An der Innenseite der Maschinenseitenwand 5 ist unterhalb des Zapfens 3 ein Schlitten 10 angeordnet. Er wird zwischen vier in die Maschinenseitenwand 5 eingeschraubten Bundschrauben 11 bis 14 geradlinig geführt (Fig. 2). An der oberen Stirnseite weist der Schlitten 10 eine Ausnehmung 15 auf. Weiterhin trägt er quer zur Schieberichtung ein Langloch 16, in das der exzentrische Zapfen 17 eines in der Mashinenseitenwand 5 gelagerten Exzenterbolzens 18 eingreift (Fig. 3). Auf letzterem ist ein Hebel 19 geklemmt, an dem ein sich drehbar im Gestell abstützender Arbeitszylinder 20 angreift. Analog dazu ist über dem aus der Maschinenseitenwand 5 herausragenden Teil des Zapfens 3 ein weiterer Schlitten 21 angeordnet. Er ist schiebbar an der Außenseite der Maschinenseitenwand 5 befestigt. Im Unterschied zum Schlitten 10 ist lediglich zur Überbrückung des durch das Zahnrad 9 bedingten größeren Abstandes zur Wand, nicht dargestellt, eine Konsole zwischengelagert. Mit dem in Figur 1 schematisch gezeigten Langloch 22 arbeitet ein Exzenterbolzen 23 zusammen, an dem unter Zwischenschaltung eines Hebels 24 ein Arbeitszylinder 25 angreift.FIG. 1 shows a cylinder 1, for example a form or transfer cylinder of an offset rotary printing press, which carries an exchangeable jacket 2. The pin 3; 4 of the cylinder 1 are in the machine side walls 5; 6 stored. The bearing of the pin 4 is housed in a wall piece, not shown, which is removable and thus opens an opening 7 in the machine side wall 6. The pin 3 is received in a bearing 8. It protrudes from the machine side wall 5 and carries a gear wheel 9. A slide 10 is arranged on the inside of the machine side wall 5 below the pin 3. It is guided in a straight line between four collar screws 11 to 14 screwed into the machine side wall 5 (FIG. 2). The carriage 10 has a recess 15 on the upper end face. Furthermore, it bears an elongated hole 16 transversely to the sliding direction, into which the eccentric pin 17 of an eccentric pin 18 mounted in the machine side wall 5 engages (FIG. 3). On the latter, a lever 19 is clamped, on which a working cylinder 20, which is rotatably supported in the frame, engages. Analogously, a further slide 21 is arranged above the part of the pin 3 protruding from the machine side wall 5. It is slidably attached to the outside of the machine side wall 5. In contrast to the carriage 10, a bracket is only temporarily stored in order to bridge the greater distance to the wall, not shown, caused by the gear wheel 9. An eccentric bolt 23 cooperates with the elongated hole 22 shown schematically in FIG. 1, on which a working cylinder 25 engages with the interposition of a lever 24.

Zum Wechseln des Mantels 2 wird dieser axial von dem Zylinder 1 durch die Öffnung 7 der Maschinenseitenwand 6 aus der Druckmaschine bewegt. Dazu werden vor der Freigabe der Öffnung 7 die Schlitten 10 und 21 mittels der Arbeitszylinder 20 und 25 in die in Figur 1 gezeichnete Stellung geschoben. Hierdurch wird der Zylinder 1 einseitig in seiner im Druckbetrieb eingenommenen Lage gehalten. Diese Position ist durch Variieren der Endlage der Exzenterbolzen 18 bzw. 23 justierbar. Dies wird durch Veränderung der Einschraubtiefe der Kolbenstange des Arbeitszylinders in den auf ihr montierten Gabelkopf, in Figur 2 in den Gabelkopf 26, bewerkstelligt. Für den Druckbetrieb des Zylinders 1 werden die Schlitten 10 und 21 durch Umsteuern der Arbeitszylinder 20 und 25 vom Zapfen 3 abgefahren.To change the jacket 2, it is axially removed from the cylinder 1 moved through the opening 7 of the machine side wall 6 from the printing press. For this purpose, before the opening 7 is released, the slides 10 and 21 are pushed into the position shown in FIG. 1 by means of the working cylinders 20 and 25. As a result, the cylinder 1 is held on one side in its position assumed in the printing operation. This position can be adjusted by varying the end position of the eccentric bolts 18 or 23. This is accomplished by changing the screwing depth of the piston rod of the working cylinder into the fork head mounted on it, in FIG. 2 into the fork head 26. For the printing operation of the cylinder 1, the slides 10 and 21 are moved from the pin 3 by reversing the working cylinders 20 and 25.

Eine weitere Ausgestaltung eines Schlittens ist in den Figuren 4 und 5 dargestellt. In diesem Falle weist der Schlitten 27 drei in seiner Schieberichtung verlaufende Langlöcher 28 bis 30 auf, in denen er mit Zapfenschrauben 31 bis 33 an der Maschinenseitenwand 34 befestigt ist. Zu letzterer wird der Schlitten 27 mit Distanzhülsen 35; 36 auf Abstand gehalten (Figur 5). Von einer Druckfeder 37 belastet stützt sich der Schlitten 27 auf einem in der Maschinenseitenwand 34 gelagerten Exzenterbolzen 38 ab. Letzterer trägt einen Hebel 39, an dem ein Arbeitszylinder mit seinem Gabelkopf 40 angelenkt ist.Another embodiment of a carriage is shown in FIGS. 4 and 5. In this case, the carriage 27 has three elongated holes 28 to 30 running in its sliding direction, in which it is fastened to the machine side wall 34 with tenon screws 31 to 33. For the latter, the carriage 27 with spacers 35; 36 kept at a distance (Figure 5). Loaded by a compression spring 37, the slide 27 is supported on an eccentric bolt 38 mounted in the machine side wall 34. The latter carries a lever 39 on which a working cylinder is articulated with its fork head 40.

Gleichermaßen wie der Schlitten 10 stützt der Schlitten 27 den Zapfen 41 eines Druckwerkzylinders, wenn dessen Mantel gewechselt werden soll. Im Druckbetrieb wird durch Umsteuern des Arbeitszylinders der Exzenterbolzen 38 verdreht, und die Druckfeder 37 bewegt den Schlitten 27 von dem Zapfen 41 weg.In the same way as the slide 10, the slide 27 supports the pin 41 of a printing unit cylinder when its jacket is to be changed. In printing operation, the eccentric pin 38 is rotated by reversing the working cylinder, and the compression spring 37 moves the carriage 27 away from the pin 41.

Die Erfindung wurde unter Anwendung zweier Schlitten beiderseits der Maschinenseitenwand beschrieben. Ebenfalls zum Gegenstand der Erfindung gehörig kann das Stützen des Zylinders auch nur mit einem außerhalb oder innerhalb der Maschinenseitenwand angeordneten Schlitten erfolgen.The invention has been described using two slides on either side of the machine side wall. Also part of the subject matter of the invention, the cylinder can also be supported only with a slide arranged outside or inside the machine side wall.
