Description

Die Erfindung betrifft einen Druckmaschinenzylinder gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a printing press cylinder according to the preamble of patent claim 1.

Bekannt ist, daß besonders bei schlanken Zylindern der Kanalschlag zu niederfrequenten Schwingungen in radialer Richtung anregt. Weiterhin wird durch die bei der Drehbewegung ausscherenden Massen eine Drehwinkelverlagerung eingeleitet, welche zu Unruhe im Antrieb führen. Eine Verstärkung des Trägheitsmomentes der Zylinder zur Verbesserung der Steifigkeit führt nicht immer zum gewünschten Erfolg, weil die damit verbundene Vergrößerung der trägen Masse die Schwingungsfrequenz und die Amplitude nicht entscheidend verbessert.It is known that the channel impact excites low-frequency vibrations in the radial direction, particularly in the case of slim cylinders. Furthermore, a shift in the angle of rotation is initiated by the masses sheared during the rotary movement, which lead to unrest in the drive. An increase in the moment of inertia of the cylinders to improve the rigidity does not always lead to the desired success because the associated increase in the inertial mass does not decisively improve the oscillation frequency and the amplitude.

Gemäß DE-OS 30 12 060 sind schwingungsunempfindliche Zylinder für Druckmaschinen bekannt, die mehrstückig aufgebaut sind und bei denen Materialien verschiedener physikalischer Eigenschaften zur Schwingungsdämpfung verwendet werden.According to DE-OS 30 12 060 vibration-insensitive cylinders for printing machines are known, which are constructed in several pieces and in which materials of different physical properties are used to dampen vibrations.

Nachteilig bei diesem Zylinder ist, daß ein mehrstückiger Aufbau einen hohen Fertigungs- und Montageaufwand erfordert. Außerdem addieren sich bei einem mehrteiligen Aufbau die Fertigungstoleranzen. Durch den Einsatz von Materialien mit verschiedenen physikalischen Eigenschaften kann es bei Temperaturveränderungen vorkommen, daß sich die Zylinder in ihrer Form verziehen. Nachteilig ist ebenfalls, daß die zwischen den Kontaktflächen der einzelnen Bauteile vorgesehenen schwingungsdämpfenden Materialien sich auf die Formstabilität des Zylinders auswirken können.The disadvantage of this cylinder is that a multi-piece structure requires a high manufacturing and assembly costs. In addition, the manufacturing tolerances add up in a multi-part construction. By using materials with different physical Properties can occur when the temperature changes that the cylinder warp in shape. Another disadvantage is that the vibration-damping materials provided between the contact surfaces of the individual components can affect the dimensional stability of the cylinder.

Gemäß EP 01 03 101 ist eine Vorrichtung zur Reduzierung der durch die Kanalüberrollung in einem Druckwerkzylinder angeregten Biegeschwingungen bekannt, welcher mit Dämpfungsmasse gefüllt ist, im Inneren elastische Achsen angeordnet sind mit einer Zusatzmasse und daß diese Zusatzmasse außermittig angebracht ist und in Berührung mit dem Mantel steht.According to EP 01 03 101, a device for reducing the bending vibrations excited by the channel rollover in a printing unit cylinder is known, which is filled with damping mass, inside elastic axes are arranged with an additional mass and that this additional mass is attached eccentrically and is in contact with the jacket .

Nachteilig bei dieser Vorrichtung ist, daß die Zusatzmasse nicht zentrisch zur Mittelachse des Zylinders angeordnet ist, so daß ein Gegengewicht bzw. ein Auswuchten erforderlich ist. Weiterhin berührt die Zusatzmasse in einem Punkt den Zylindermantel, was insofern von Nachteil ist, als daß beim Auftreten von Schwingungen eine ständige mechanische Beanspruchung des Zylindermantels und der Zusatzmasse an immer der gleichen Stelle erfolgt, was zur Abflachung oder Ermüdung der Materialien und zum Verlust des Dämpfungseffektes führen kann. Ein mehrteiliger Aufbau erfordert ebenfalls einen hohen Fertigungs- und Montageaufwand.A disadvantage of this device is that the additional mass is not arranged centrally to the central axis of the cylinder, so that a counterweight or balancing is required. Furthermore, the additional mass touches the cylinder jacket at one point, which is disadvantageous in that, when vibrations occur, the cylinder jacket and the additional mass are always subjected to the same mechanical stress, which leads to flattening or fatigue of the materials and loss of the damping effect can lead. A multi-part structure also requires a lot of manufacturing and assembly work.

Weiterhin ist gemäß EP 01 03 102 eine weitere Variante der o. g. Vorrichtung bekannt geworden, welche an der Innenseite des Mantels des Druckwerkzylinders ein die Schwingungen übertragender Steg befestigt ist, der mit einem im Zylinderkanal liegenden Absorberstab verbunden ist. Der Absorberstab besitzt Zusatzmassen und ist in der Dämpfungsmasse eingebettet. Auch hier tritt neben den bereits schon genannten Nachteilen insbesondere der Nachteil ein, daß ein mehrteiliger Aufbau einen hohen Fertigungs- und Montageaufwand erfordert.Furthermore, according to EP 01 03 102, a further variant of the above-mentioned device has become known, which is based on the On the inside of the jacket of the printing unit cylinder, a web that transmits the vibrations is attached, which is connected to an absorber rod located in the cylinder channel. The absorber rod has additional masses and is embedded in the damping mass. Here too, in addition to the disadvantages already mentioned, there is in particular the disadvantage that a multi-part construction requires high outlay in terms of production and assembly.

Der Erfindung liegt die Aufgabe zugrunde, einen Druckmaschinenzylinder mit Schwingungsdämpfung zu schaffen, welcher kostengünstig mit hoher Präzision herstellbar ist, dabei gute Dämpfungseigenschaften aufweist und einer Durchbiegung des Zylinders infolge Eigengewicht entgegenwirkt.The invention has for its object to provide a printing press cylinder with vibration damping, which is inexpensive to manufacture with high precision, has good damping properties and counteracts bending of the cylinder due to its own weight.

Erfindungsgemäß wird diese Aufgabe durch die Merkmale des kennzeichnenden Teils des Anspruches 1 gelöst.According to the invention, this object is achieved by the features of the characterizing part of claim 1.

Die Vorteile der Erfindung bestehen insbesondere darin, daß der im Zylinderraum befindliche Kern eine Gegenmasse zum Zylindermantel bildet und das schwingungsdämpfende Material die Schwingungen umwandelt bzw. die Resonanzschwingungen so verstimmt, daß diese Schwingungen unschädlich werden. Durch die einteilig gegossene Ausführung des Druckmaschinenzylinders werden bei niedrigen Herstellungskosten geringe Fertigungstoleranzen ermöglicht. Durch die Anordnung eines koaxial um den Kern verlaufenden ringförmigen Steges, der mit dem Zylindermantel in Verbindung steht, wird eine axiale Durchbiegung des Druckmaschinenzylinders, insbesondere bei schlanken Zylindern, vermieden.The advantages of the invention are in particular that the core located in the cylinder space forms a countermass to the cylinder jacket and the vibration-damping material converts the vibrations or detunes the resonance vibrations so that these vibrations become harmless. The one-piece cast design of the printing press cylinder enables low manufacturing tolerances at low manufacturing costs. The arrangement of an annular web which runs coaxially around the core and which is connected to the cylinder jacket, axial deflection of the printing press cylinder, in particular in the case of slim cylinders, is avoided.

Durch die Anordnung von Kugeln bzw. vormontierten Kugelbehältern im Inneren des Druckmaschinenzylinders wird sowohl eine Gegenmasse zum Zylindermantel gebildet, als auch gleichzeitig ein schwingungsdämpfendes Material geschaffen. Bei der Verwendung von Kugelbehältern können dieselben unmittelbar in der Nähe der Stelle angebracht werden, an welcher die Schwingungen abgeleitet werden.The arrangement of balls or preassembled ball containers in the interior of the printing press cylinder not only forms a countermass to the cylinder jacket, but also creates a vibration-damping material. When using spherical containers, they can be attached directly in the vicinity of the point at which the vibrations are dissipated.

Die Erfindung soll nachstehend an mehreren Ausführungsbeispielen erläutert werden. Die zugehörigen Zeichnungen zeigen in

Fig. 1 zeigt einen Längsschnitt durch einen erfindungsgemäßen Druckmaschinenzylinder 1 dargestellt, jedoch ohne einen Kanal und ohne Greifereinrichtung. Die üblicherweise in einem oder mehreren Kanälen 32 angeordneten Einrichtung, wie Platten- oder Gummituchspann- oder Greifereinrichtungen werden auch bei den folgenden Ausführungsvarianten generell nicht dargestellt. Die Zylinderkanäle sind in Fig. 2 dargestellt. Der Druckmaschinenzylinder 1 besteht aus einem einteiligen rotationssymmetrischen Gußkörper, welcher den Zylindermantel 2 und zwei Stirnseiten 3; 4 umfaßt.Fig. 1 shows a longitudinal section through a printing press cylinder 1 according to the invention, but without a channel and without a gripper device. The device usually arranged in one or more channels 32, such as plate or blanket tensioning or gripping devices, is also generally not shown in the following embodiment variants. The cylinder channels are in FIG. 2 shown. The printing press cylinder 1 consists of a one-piece rotationally symmetrical cast body, which the cylinder jacket 2 and two end faces 3; 4 includes.

Die Fig. 1 zeigt im Längsschnitt eine erfindungsgemäße Lösung für einen einteiligen Druckmaschinenzylinder 1 mit Schwingungsdämpfung. Der Zylindermantel 2 ist mit den Stirnseiten 3; 4 und die Stirnseiten 3; 4 sind mit den in axialer Richtung verlaufenden Achszapfen 12; 13 fest verbunden. In dem Raum, der von dem Zylindermantel 2 und den Stirnseiten 3; 4 des Druckmaschinenzylinders 1 gebildet wird, sind Kugeln 37 eingefüllt. Die Kugeln 37 besitzen vorzugsweise einen Durchmesser von 2,5 bis 3 mm und sollten aus Stahl sein. Die Kugeln 37 können durch die Einfüllöffnungen 26 eingebracht werden. Die Kugeln 37 dienen sowohl als Kern als auch als schwingungsdämpfendes Material. Das Verdichten der Kugeln 37 kann durch Rütteln erfolgen. Zusätzlich kann noch eine Vorspann-Einrichtung im Inneren des Druckmaschinenzylinders 1 angeordnet sein, welche die Kugeln 37 im Bedarfsfalle weiter verdichtet. Der Zylinder kann aber auch mehrteilig ausgeführt sein.1 shows in longitudinal section a solution according to the invention for a one-piece printing press cylinder 1 with vibration damping. The cylinder jacket 2 is with the end faces 3; 4 and the end faces 3; 4 are with the axles extending in the axial direction 12; 13 firmly connected. In the space from the cylinder jacket 2 and the end faces 3; 4 of the printing press cylinder 1 is formed, balls 37 are filled. The balls 37 preferably have a diameter of 2.5 to 3 mm and should be made of steel. The balls 37 can be introduced through the filling openings 26. The balls 37 serve both as a core and as a vibration-damping material. The balls 37 can be compacted by shaking. In addition, a pretensioning device can be arranged in the interior of the printing press cylinder 1, which further compresses the balls 37 if necessary. The cylinder can also be made in several parts.

Durch den Kanalschlag wird der Zylindermantel 2 zu Schwingungen angeregt. Diese Schwingungen werden auf die an der Innenseite des Zylindermantels 2 anliegenden Kugeln 37 übertragen. Durch die verlustbehafteten Stoß- und Bewegungsvorgänge der aneinanderliegenden Kugeln 37 nehmen die Schwingungen mehr und mehr ab. Die Dämpfungswirkung kann noch erhöht werden, wenn zusätzlich noch viskose Dämpfungsanteile, wie Öle oder Fette verwendet werden.The cylinder jacket 2 is excited to vibrate by the channel blow. These vibrations are transmitted to the balls 37 abutting the inside of the cylinder jacket 2. The vibrations decrease more and more due to the lossy impact and movement processes of the adjacent balls 37. The damping effect can be increased if additional still viscous damping components such as oils or greases are used.

Gemäß Fig. 2 ist mit dem Querschnitt durch einen Druckmaschinenzylinder eine Ausführungsvariante nach Fig. 1 gezeigt. Der Zylindermantel 2 ist mit Zylinderkanälen 32 dargestellt. Der Druckmaschinenzylinder 1 ist gemäß Fig. 7 ausgeführt, mit der Besonderheit, daß nicht der gesamte Innenraum, der durch den Zylindermantel 2 und die Stirnseiten 3; 4 begrenzt ist, mit Kugeln 37 ausgefüllt ist, sondern daß zwei mit Kugeln gefüllte Behälter 38 in axialer Richtung 6 in der Nähe der Zylinderkanäle 32 an der Innenseite des Zylindermantels 2 angebracht sind. Der Zylinderkanal ist der Bereich, in dem die Schwingungen erzeugt werden. Es können ein oder mehrere Kugelbehälter montiert sein. Vorteilhaft ist es auch, mehrere Kugelbehälter so anzubringen, daß ein zusätzliches Auswuchten entfallen kann. Zweckmäßig ist, Stahlkugeln mit einem Durchmesser von 2,5 bis 3 mm einzusetzen.According to FIG. 2, an embodiment variant according to FIG. 1 is shown with the cross section through a printing press cylinder. The cylinder jacket 2 is shown with cylinder channels 32. The printing press cylinder 1 is designed according to FIG. 7, with the special feature that not the entire interior space, which is caused by the cylinder jacket 2 and the end faces 3; 4 is limited, filled with balls 37, but that two containers 38 filled with balls are attached in the axial direction 6 in the vicinity of the cylinder channels 32 on the inside of the cylinder jacket 2. The cylinder channel is the area in which the vibrations are generated. One or more ball containers can be installed. It is also advantageous to attach several ball containers so that additional balancing can be omitted. It is advisable to use steel balls with a diameter of 2.5 to 3 mm.

Der Druckmaschinenzylinder kann einteilig oder auch mehrteilig aufgebaut sein. Er muß eine stirnseitige Öffnung zum Einbringen und Montieren der Kugelbehälter besitzen.The printing press cylinder can be constructed in one part or in several parts. It must have an opening at the front for inserting and mounting the ball container.

Die gefüllten Kugelbehälter werden durch die stirnseitigen Öffnungen im Druckmaschinenzylinder so angebracht, daß diese mit einer Fläche am inneren Zylindermantel fest anliegen.
