Description

Die Erfindung betrifft einen Zylinder einer Rotationsdruckmaschine bestehend aus einem Zylinderballen mit lösbar verbundenen Lagerzapfen gemäß dem Oberbegriff des Anspruches 1.The invention relates to a cylinder of a rotary printing press consisting of a cylinder barrel with a detachably connected bearing journal according to the preamble of claim 1.

Die DE 30 42 170 A1 zeigt einen Zylinder, dessen Lagerzapfen direkt an seinen Ballen angeschraubt sind.DE 30 42 170 A1 shows a cylinder, the journal of which is screwed directly onto its bale.

Aus der US 35 81 659 A und der FR 12 75 904 sind Zylinder bekannt, deren Zapfen lösbar befestigt sind und die nach dem Lösen der Zapfen eine plane Stirnfläche aufweisen.From US 35 81 659 A and FR 12 75 904 cylinders are known, the pins are releasably attached and which have a flat end face after loosening the pin.

Die DE-PS 8 00 932 beschreibt einen Kalander mit herausnehmbaren Walzen. Die Walzen sind mit abnehmbaren Zapfen versehen, wobei die Zapfen eine konische Vertiefung und ein Ballen konische Wellenstümpfe aufweisen.DE-PS 8 00 932 describes a calender with removable rollers. The rollers are provided with removable pins, the pins having a conical recess and a ball of conical shaft ends.

Nachteilig ist hierbei, daß zumindest ein Zapfen weit axial verschiebbar im Gestell angeordnet ist.The disadvantage here is that at least one pin is arranged axially displaceable in the frame.

Der Erfindung liegt die Aufgabe zugrunde, einen aus Zylinderballen und daran angeflanschten Lagerzapfen bestehenden Zylinder einer Rotationsdruckmaschine zu schaffen, bei dem der Zylinderballen von den Lagerzapfen getrennt werden kann und ein Lagerzapfen axial nur minimal bewegt wird.The invention has for its object to provide a cylinder consisting of a cylinder ball and flanged bearing journal of a rotary printing press, in which the cylinder ball can be separated from the journal and a journal is axially moved only minimally.

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.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß bei dem erfindungsgemäßen Zylinder die Lagerzapfen annähernd ortsfest in den Gestellen bei Entnahme des Zylinderballens verbleiben. Der Aufbau der Lagerungen in den Gestellen wird somit einfach und kostengünstig.
Der Abstand zwischen den Gestellen kann minimiert werden, da kein Raum für den axialen Versatz der Lagerzapfen berücksichtigt werden muß. Somit wird die Steifigkeit des gesamten Zylinders erhöht, was eine verbesserte Druckqualität zu Folge hat.
Durch die lösbare Flanschverbindung ist während des Betriebes der Zylinderballen fest mit den Lagerzapfen verbunden, wodurch im Vergleich zum Stand der Technik keine zusätzlichen Axialkräfte auf die Zylinderlagerungen auftreten.
Sind die Flansche als Schmitzringe ausgeführt, können beim erfindungsgemäßen Zylinder "Hülsen" trotz dieser vorhandenen Schmitzringe in einfacher Weise montiert werden.
Durch gleichzeitige Verwendung von Hülsen und Schmitzringen wird ein extrem ruhiger Lauf der Rotationsdruckmaschine erreicht, wodurch höchste Druckqualität erzielt wird.
Eine hochgenaue Zentrierung von Lagerzapfen und Zylinderballen wird durch zusammenwirkende Konen ermöglicht.The advantages that can be achieved with the invention exist in particular in that in the cylinder according to the invention the journals remain approximately stationary in the frames when the cylinder barrel is removed. The structure of the bearings in the racks is thus simple and inexpensive.
The distance between the frames can be minimized since no space has to be taken into account for the axial offset of the bearing pins. This increases the rigidity of the entire cylinder, which results in improved print quality.
Due to the detachable flange connection, the cylinder barrel is firmly connected to the bearing journal during operation, which means that no additional axial forces occur on the cylinder bearings in comparison to the prior art.
If the flanges are made as bearer rings, "sleeves" can be installed in a simple manner in spite of these bearer rings in the cylinder according to the invention.
The simultaneous use of sleeves and bearer rings ensures that the rotary printing press runs extremely smoothly, thereby achieving the highest print quality.
A highly precise centering of the bearing journal and cylinder barrel is made possible by interacting cones.

Ein Zylinder 1 einer Rotationsdruckmaschine besteht im wesentlichen aus einem Zylinderballen 2, an dessen Stirnseiten 3, 4 jeweils ein abnehmbarer Lagerzapfen 6, 7 befestigt ist. Mittels dieser Lagerzapfen 6, 7 ist der Zylinder 1 um eine Drehachse 8 drehbar in Gestellen 9, 11 gelagert.
An diesen Lagerzapfen 6, 7 ist jeweils ein z. B. als Schmitzring 12 ausgeführter Flansch angeformt und an einer dem Zylinderballen 2 zugewandten Stirnseite 13 mit einer konischen Vertiefung 14 versehen. Diese konische Vertiefung 14 liegt konzentrisch zur Drehachse 8 des Zylinders 1. Der Zylinderballen 2 kann beispielsweise als Gummizylinder ausgeführt sein. Hierzu kann eine Mantelfläche 16 des Zylinderballens 2 mit einer endlosen Gummibeschichtung 17 versehen sein. Diese Gummibeschichtung 17 kann auf die Mantelfläche 16 aufvulkanisiert, geklebt oder beispielsweise als hülsenförmiges Rohr, ein sogenannter Sleeve, aufgebracht sein. Der Schmitzring 12 ist mit mehreren am Umfang verteilten Bohrung 18 versehen, durch die Schrauben 19 reichen, die mit Gewindebohrungen 21 des Zylinderballens 2 zusammenwirken. Dadurch ist der jeweilige Lagerzapfen 6, 7 mit dem Zylinderballen 2 verschraubt.A cylinder 1 of a rotary printing press essentially consists of a cylinder barrel 2, on the end faces 3, 4 of which a removable bearing journal 6, 7 is fastened. By means of these journals 6, 7, the cylinder 1 is mounted in frames 9, 11 so as to be rotatable about an axis of rotation 8.
On these journals 6, 7 is a z. B. formed as a bearer ring 12 flange and provided on a cylinder ball 2 facing end face 13 with a conical recess 14. This conical recess 14 is concentric with the axis of rotation 8 of the cylinder 1. The cylinder barrel 2 can be designed, for example, as a rubber cylinder. For this purpose, an outer surface 16 of the cylinder barrel 2 can be provided with an endless rubber coating 17. This rubber coating 17 can be vulcanized onto the outer surface 16, glued or applied, for example, as a sleeve-shaped tube, a so-called sleeve be. The bearer ring 12 is provided with a plurality of holes 18 distributed around the circumference, through which screws 19 extend, which interact with threaded holes 21 of the cylinder barrel 2. As a result, the respective bearing journal 6, 7 is screwed to the cylinder barrel 2.

In dem Zylinderballen 2 ist mindestens eine Zentrier- und Lösevorrichtung 22 angeordnet. Diese Zentrier- und Lösevorrichtung 22 besteht im wesentlichen aus zwei Zapfen 23, einer Druckfeder 24 und mindestens einem Stellmittel 26. Die Zapfen 23 sind in einer sich axial erstreckenden Bohrung 27 des Zylinderballens 2 konzentrisch und axial verschiebbar bezüglich der Drehachse 8 des Zylinders 1 gelagert. An einem den Lagerzapfen 6, 7 zugewandten Ende sind die ansonsten zylindrischen Zapfen 23 mit einem konischen Ende 28 versehen. Dieses konische Ende 28 und die konische Vertiefung 14 sind aufeinander angepaßt. Am gegenüberliegenden, zweiten Ende 29 des Zapfens 23 greift die Druckfeder 24 an, die sich gegen eine in der Bohrung 27 des Zylinderballens 2 befindlichen Anschlagscheibe 31 abstützt. Zusätzlich ist in dieses zweite Ende 29 des Zapfens 23 eine Gewindebohrung 32 eingebracht, in die eine mit einem Bund 33 versehene Zugschraube 34 eingreift, wobei sich der Bund 33 ebenfalls an der Anschlagscheibe 31 abgestützt. Diese Zugschraube 34 kann mittels eines Antriebes, z. B. Pneumatikmotor betätigt werden, oder wie im vorliegenden, ersten Ausführungsbeispiel mit einem Innensechskant 36 versehen sein. Zur Betätigung der Zugschraube 34 ist der verdrehgesicherte Zapfen 23 und sind die Lagerzapfen 6, 7 mit einer durchgehenden Bohrung 37 versehen.At least one centering and releasing device 22 is arranged in the cylinder barrel 2. This centering and releasing device 22 essentially consists of two pins 23, a compression spring 24 and at least one adjusting means 26. The pins 23 are mounted concentrically and axially displaceably with respect to the axis of rotation 8 of the cylinder 1 in an axially extending bore 27 of the cylinder barrel 2. The otherwise cylindrical pins 23 are provided with a conical end 28 at one end facing the bearing pins 6, 7. This conical end 28 and the conical recess 14 are adapted to one another. The compression spring 24, which is supported against a stop disk 31 located in the bore 27 of the cylinder barrel 2, engages at the opposite, second end 29 of the pin 23. In addition, a threaded bore 32 is made in this second end 29 of the pin 23, into which a tension screw 34 provided with a collar 33 engages, the collar 33 also being supported on the stop disk 31. This lag screw 34 can by means of a drive, for. B. pneumatic motor operated, or as in the present, first embodiment with a Hexagon socket 36 may be provided. To actuate the tension screw 34 is the non-rotating pin 23 and the bearing pins 6, 7 are provided with a continuous bore 37.

Natürlich ist es auch möglich die Anschlagscheibe 31 entfallen zu lassen und die beiden gegenüberliegenden Zapfen 23 mittels einer gemeinsamen Druckfeder 24 und einer gemeinsamen Gewindespindel, die dann ein Rechts- und ein Linksgewinde aufweist, zu verbinden.Of course, it is also possible to omit the stop disk 31 and to connect the two opposite pins 23 by means of a common compression spring 24 and a common threaded spindle, which then has a right-hand and a left-hand thread.

In einem zweiten Ausführungsbeispiel ist der Zapfen 23 als mit einem Druckmittel beaufschlagbarer Kolben ausgeführt. Hierzu ist beispielsweise das konische Ende 28 des Zapfens 23 mit einem kleineren Durchmesser als die Bohrung 27 des Zylinderballens 2 abgesetzt. Der Zylinderballen 2 ist stirnseitig mit einer dem abgesetzten Ende 28 des Zentierbolzens 23 anpaßten, mit einer Dichtung 38 versehenen Abdeckscheibe 39 verschlossen. Somit wird zwischen dem abgesetzten Ende 28 des Zapfens 23 und der Abdeckscheibe 39 eine Druckkammer 41 gebildet. Diese Druckkammer 41 ist mittels eines Kanales 42 mit einer im Zylinderballen 2 befindlichen Anschlußöffnung 43 verbunden.In a second exemplary embodiment, the pin 23 is designed as a piston which can be acted upon by a pressure medium. For this purpose, for example, the conical end 28 of the pin 23 is offset with a smaller diameter than the bore 27 of the cylinder barrel 2. The cylinder barrel 2 is closed at the end with a cover plate 39 which is adapted to the offset end 28 of the centering bolt 23 and is provided with a seal 38. A pressure chamber 41 is thus formed between the stepped end 28 of the pin 23 and the cover plate 39. This pressure chamber 41 is connected by means of a channel 42 to a connection opening 43 located in the cylinder barrel 2.

Ebenso ist es denkbar beide Zapfen 23 mittels eines gemeinsamen, druckmittelbaufschlagbaren Arbeitszylinder zu koppeln und somit auf die im Zylinderballen 2 eingearbeitete Druckkammern 41 zu verzichten.It is also conceivable to couple both pins 23 by means of a common working cylinder which can be pressurized with pressure medium and thus to the cylinder cylinder 2 to dispense with incorporated pressure chambers 41.

Zur Entnahme des Zylinderballens 2 aus der Rotationsdruckmaschine werden die die Schmitzringe 12 und den Zylinderballen 2 verbindende Schrauben 19 gelöst. Hierzu können beispielsweise in den Gestellen 9, 11 nichtdargestellte Öffnungen vorgesehen sein. Durch die Druckfeder 24 werden die Schmitzringe 12 bzw. ein Schmitzring 12 und der Zylinderballen 2 um einen kleinen Weg axial verschoben. Die Größe dieses Weges ergibt sich aus einem Axialspiel der Lagerungen der Lagerzapfen 6, 7 im Gestell 9, 11. Im ersten Ausführungsbeispiel wird mittels eines durch die jeweilige Bohrung 37 von Lagerzapfen 6, 7 und Zapfen 23 reichenden Werkzeuges die jeweilige Zugschraube 34 betätigt und die Zapfen 23 axial von den Schmitzringen 12 weg in ein Inneres des Zylinderballens 2 gezogen bis die konischen Enden 28 zumindest mit den Stirnseiten 3, 4 des Zylinderballens 2 deckungsgleich sind. Der Zylinderballen 2 kann nun aus zwischen den in den Gestellen 9, 11 verbleibenden Lagerzapfen 6, 7 entnommen werden.To remove the cylinder barrel 2 from the rotary printing machine, the screws 19 connecting the bearer rings 12 and the cylinder barrel 2 are loosened. For this purpose, openings (not shown) can be provided in the frames 9, 11, for example. The bearer rings 12 or a bearer ring 12 and the cylinder barrel 2 are axially displaced a small distance by the compression spring 24. The size of this path results from an axial play of the bearings of the journals 6, 7 in the frame 9, 11. In the first exemplary embodiment, the respective tension screw 34 is actuated by means of a tool reaching through the respective bore 37 of journals 6, 7 and journals 23 and the Pin 23 is pulled axially away from the bearer rings 12 into an interior of the cylinder barrel 2 until the conical ends 28 are at least congruent with the end faces 3, 4 of the cylinder barrel 2. The cylinder barrel 2 can now be removed from between the journals 6, 7 remaining in the frames 9, 11.

Im zweiten Ausführungsbeispiel werden zur Bewegung der Zapfen 23 in das Innere des Zylinderballens 2 die Anschlußöffnungen 43 mit einer Druckmittelquelle verbunden. Somit wird die jeweilige Druckkammer 41 mit Druckmittel beaufschlagt und die benötigte Axialbewegung der Zapfen 23 erzeugt.In the second exemplary embodiment, the connection openings 43 are connected to a pressure medium source for moving the pins 23 into the interior of the cylinder barrel 2. Thus, the respective pressure chamber 41 is pressurized and the required axial movement of the pins 23 is generated.
