Description

Die Erfindung betrifft einen Druckwerkzylinder mit einer Vorrichtung zur Reduzierung der durch die Kanalüberrollung angeregten Dreh- und Bie- geschwingungen mit mindestens einem im Druckwerkzylinder angeordneten Dämpfungselement, das durch einen an der Innenseite des Mantels des Druckwerkzylinders befestigten Steg durch Stöße beim Oberrollen der Zylinderkanäle angeregt wird.The invention relates to a printing unit cylinder having a device for reducing the excited by the groove roll turning and bending gesc h wingungen with at least one arranged in the printing unit cylinder damping element excited by an attached to the inside of the casing of the printing unit cylinder web by impacts when the upper rollers of the cylinder channels becomes.

Aus dem deutschen Patent 32 30 120 ist ein Druckwerkzylinder bekannt, in dem zur Reduzierung der Biegeschwingungen bei der Kanalüberrollung an der Innenseite des Mantels des Druckwerkzylinders Stege befestigt sind, die den Druckwerkzylinder etwa diametrisch durchsetzen. Ober diese Stege werden die bei der Überrollung der Zylinderkanile auftretenden Schwingungen einem parallel zum Zylinderkanal liegenden Absorberstab zugeführt, der mit einer Dämpfungsmasse umgeben ist. Zur Unterdrückung von Drehschwingungen sind an den Enden des Absorberstabes propellerartig Flügel befestigt. Bei diesem bekannten Druckwerkszylinder werden Schwingungen absorbiert.From the German patent 32 30 120, a printing unit cylinder is known, in which webs are secured to reduce the bending vibrations when the channel is rolled over on the inside of the jacket of the printing unit cylinder, which pass through the printing unit cylinder approximately diametrically. Via these webs, the vibrations that occur when the cylinder channels are rolled over are fed to an absorber rod that is parallel to the cylinder channel and is surrounded by a damping mass. To suppress torsional vibrations, propeller-like wings are attached to the ends of the absorber rod. Vibrations are absorbed in this known printing cylinder.

Aufgabe der Erfindung ist es, einen Druckwerkzylinder der vorangehenden Art so weiterzubilden, daß neben der Vernichtung bzw. Dämpfung von Schwingungen durch Absorbtion zur Unterdrückung der Grundfrequenz für Biege- und Drehschwingungen auch der "elastische Stoß", der beim Oberrollen der Zylinderkanile auftritt, den Dämpfungsmitteln zugeleitet wird. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruchs 1 gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen und aus der Beschreibung in Verbindung mit den Zeichnungen.The object of the invention is to develop a printing unit cylinder of the preceding type so that in addition to the destruction or damping of vibrations by absorption to suppress the fundamental frequency for bending and torsional vibrations, the "elastic shock" that occurs when the cylinder channels roll over, the damping means is forwarded. This object is achieved by applying the features of the characterizing part of claim 1. Further developments result from the subclaims and from the description in connection with the drawings.

In diesen zeigen jeweils schematisch:

  • Fig.l und 2: Längsschnitte durch Druckwerkzylinder mit den erfindungsgemäßen Dämpfungselementen,
  • Fig.3: einen Querschnitt erfindungsgemäßer Dämpfungselemente und
  • Fig.4 ein weiteres Ausführungsbeispiel von erfindungsgemäßen Dämpfungselementen.
Each of these shows schematically:
  • 1 and 2: longitudinal sections through printing unit cylinders with the damping elements according to the invention,
  • 3 shows a cross section of damping elements according to the invention and
  • 4 shows a further embodiment of damping elements according to the invention.

Fig.l zeigt im Längsschnitt einen Druckwerkzylinder mit einem nicht näher dargestellten, in Achsrichtung verlaufenden Kanal, in dem in üblicher Weise Mittel zum Befestigen von Gummitüchern oder Druckplatten positioniert sind. Der in Fig.l dargestellte Druckwerkzylinder umfaßt einen Zylindermantel 1 und Zylinderzapfen 2, 3, über die der dargestellte Druckwerkzylinder in Seitenwänden gelagert werden kann.Fig.l shows in longitudinal section a printing unit cylinder with a channel, not shown, extending in the axial direction, in which means for fastening rubber blankets or printing plates are positioned in the usual manner. The printing unit cylinder shown in Fig.l comprises a cylinder jacket 1 and cylinder pin 2, 3, via which the printing unit cylinder shown can be stored in side walls.

Da in der Mitte der Druckwerkzylinder die Schwingungen am größten sind, wird bei der Ausführungsform gemäß Fig.l ein den Zylinder diametrisch durchsetzender Steg angeordnet, der mit seinen beiden Enden am Zylindermantel 1 befestigt ist. Ober diesen Steg 4 werden bei der Kanalüberrollung auftretende Schwingungen Dämpfungselementen 7 bis 10 vorzugsweise über Arme 5 und 6, die etwa kreuzförmig mit dem Steg 4 verbunden sind, zugeführt. Die Dämpfungselemente bestehen vorzugsweise aus Dreh- und Biegefedern. Wie Fig.l erkennen läßt, sind symmetrisch beiderseits des Obertragungssteges 4 Dämpfungselemente 7, 8 bzw. 9, 10 angeordnet. Diese sind jeweils L-förmig ausgestaltet. An einer Seite ist jeweils ein Schenkel mit dem Ende einer der Arme 5, 6 verbunden, während ein Ende des anderen Schenkels dicht unterhalb des Zylindermantels 1 endet. Dadurch wird erfindungsgemäß eine Stoßstelle 11 zwischen dem jeweiligen Dämpfungselement 7 bis 10 gebildet, wodurch in vorteilhafter Weise der bei der Kanalüberrollung auftretende elastische Stoß über diese Stoßstellen 11 den Dämpfunngselementen in Form von Dreh- und Biegefedern 7 bis 10 zugeleitet werden kann, um insbesondere die erste Schwingung (Grundfrequenz) für Biege- und Drehschwingungen zu dämpfen. Die Dämpfungselemente 7 bis 10 sind in elastischem Material 12 eingebettet.Since the vibrations are greatest in the middle of the printing unit cylinder, in the embodiment in accordance with FIG. Via this web 4, vibrations occurring during the channel rollover are supplied to damping elements 7 to 10, preferably via arms 5 and 6, which are connected to the web 4 in an approximately cross shape. The damping elements preferably consist of torsion and bending springs. As Fig.l shows, 4 damping elements 7, 8 and 9, 10 are arranged symmetrically on both sides of the transfer web. These are each L-shaped. On one side, one leg is connected to the end of one of the arms 5, 6, while one end of the other leg ends just below the cylinder jacket 1. As a result, according to the invention, a joint 11 is formed between the respective damping elements 7 to 10, which advantageously results in the elastic impact that occurs during the channel rollover via these joints 11 and the damping elements in the form of torsion and bending springs 7 to 10 can be supplied, in particular to dampen the first vibration (fundamental frequency) for bending and torsional vibrations. The damping elements 7 to 10 are embedded in elastic material 12.

Erfindungsgemäß bietet somit der in Fig.l dargestellte Druckwerkzylinder die Möglichkeit, bei der Kanalüberrollung auftretende Dreh- und Biegeschwingungen über mit dem Zylindermantel 1 fest verbundene Stege den Dämpfungselementen 7 bis 10 zuzuleiten, so baß diese absorbiert werden und außerdem werden an die Dämpfunselemente 7 bis 10 über die Stoßstellen 11 bei der Kanalüberrollung auftretende elastische Stöße übertragen und gedämpft.According to the invention, the printing unit cylinder shown in FIG. 1 thus offers the possibility of conveying torsional and bending vibrations occurring in the channel rollover to the damping elements 7 to 10 via webs which are firmly connected to the cylinder jacket 1, so that these are absorbed and, in addition, are absorbed by the damping elements 7 to 10 transmitted and damped over the joints 11 occurring in the channel rollover elastic shocks.

Fig.2 zeigt einen Längsschnitt durch einen weiteren Druckwerkzylinder, bei dem die Dämpfungselemente und Übertragungsstege abgewandelt sind. Der in Fig.2 dargestellte Druckwerkzylinder umfaßt einen Zylindermantel 13 und wird über Achszapfen 14 und 15 gelagert. Im Gegensatz zu der Ausführungsform gemäß Fig.l wird hier die Stoßstelle 11 durch einen in der Zylindermitte angeordneten Steg 16 gebildet, der mit seinen beiden Enden dicht unterhalb des Zylindermantels 13 endet. In etwa Kreuzform sind an dem Steg 16 Übertragungsarme 17 und 18 angeordnet, über die die Stöße den Dämpfungselementen 19 bis 22 zugeführt werden. Ähnlich wie bei der Ausführungsform gemäß Fig.l werden auch bei der Ausführungsform gemäß Fig.2 die Arme 17, 18 von den Dämpfungselementen 19 bis 22, die z.B. eine rohrförmige Gestalt aufweisen können, umfaßt. Jedoch ist jeweils ein Schenkel der L-förmigen Dämpfungselemente 19 bis 22 direkt mit dem Zylindermantel 13 verbunden. Dadurch wird zum einen erreicht, daß die gesamte Anordnung in der gewünschten Lage im Inneren des Druckwerkzylinders positioniert wird und zum anderen werden über die mit dem Zylindermantel 13 befestigten Schenkel der Dämpfungselemente 19 bis 22 die bei der Kanalüberrollung auftretenden Schwingungen übertragen.2 shows a longitudinal section through another printing unit cylinder, in which the damping elements and transmission webs are modified. The printing unit cylinder shown in FIG. 2 comprises a cylinder jacket 13 and is supported via axle journals 14 and 15. In contrast to the embodiment according to FIG. 1, the joint 11 is formed here by a web 16 arranged in the middle of the cylinder, which ends at both ends just below the cylinder jacket 13. In approximately cross shape 16 transmission arms 17 and 18 are arranged on the web, via which the shocks are fed to the damping elements 19 to 22. Similar to the embodiment according to Fig. 1, the arms 17, 18 of the damping elements 19 to 22, which e.g. may have a tubular shape. However, one leg of the L-shaped damping elements 19 to 22 is connected directly to the cylinder jacket 13. In this way, on the one hand it is achieved that the entire arrangement is positioned in the desired position inside the printing unit cylinder and, on the other hand, the vibrations occurring when the channel is overrun are transmitted via the legs of the damping elements 19 to 22 which are fastened to the cylinder jacket 13.

Eine besonders vorteilhafte Konstruktion zeigt die Schnittdarstellung gemäß Fig.3. Vom Zylindermantel 23 umgeben sind Dämpfungselemente 24 und 25 vorzugsweise in der Mitte positioniert, auf denen mindestens eine Stoßübertragungsscheibe 26 angeordnet ist. Die Stoßübertragungsscheibe 26 weist Ausnehmungen 27, 28 auf, in die mit dem Zylindermantel 23 verbundene Obertragungsstücke 29 ragen. Dadurch werden Stoßstellen 11 gebildet, die sowohl Radialstöße als auch Drehstöße aufnehmen bzw. übertragen können. Seitlich des Dbertragungsstückes 29 liegen die Stoßstellen 11 zur Obertragung von Drehstößen, während in Richtung Druckzylindermitte die Radialstoßübertragung erfolgt. Es versteht sich, daß auch den Dämpfungselementen 25 über Stege die Schwingungen zugeführt werden, die direkt vom Zylindermantel abgenommen werden.The sectional view according to FIG. 3 shows a particularly advantageous construction. Damping elements 24 and 25 are preferably surrounded by the cylinder jacket 23, on which at least one shock transmission disk 26 is arranged. The shock transmission disc 26 has recesses 27, 28 into which the transmission elements 29 connected to the cylinder jacket 23 protrude. As a result, joints 11 are formed, which can absorb or transmit both radial impacts and torsional impacts. To the side of the transmission piece 29 are the joints 11 for the transmission of rotary shocks, while the radial shock transmission takes place in the direction of the pressure cylinder center. It goes without saying that the damping elements 25 are also fed with vibrations via webs, which are taken directly from the cylinder jacket.

Letztlich zeigt Fig.4 eine weitere Variante des erfindungsgemäßen Druckwerkzylinders, bestehend aus einem Zylindermantel 30 und Achszapfen 31, 32. Mit dem Zylindermantel 30 verbunden ist ein 0bertragungssteg 33, an dem jeweils an einer Seite Dbertragungsarme 34, 35 befestigt sind, über die den Dämpfungselementen 36 bis 39 direkt vom Zylindermantel 30 Schwingungen zugeführt werden. Zusätzlich werden durch Stoßaufnahmestücke 40 bis 43, die mit den Dämpfungselementen 36 bis 39 verbunden sind, Stoßstellen 11 gebildet, über die vorteilhaft über den gleichen Pfad 33 zugeführte elastische Stöße bei der Kanalüberrollung übertragen und in das System aus den Dämpfungselementen 36 bis 39 zugeleitet werden.Finally, FIG. 4 shows a further variant of the printing unit cylinder according to the invention, consisting of a cylinder jacket 30 and axle journal 31, 32. Connected to the cylinder jacket 30 is a transmission web 33, to which transmission arms 34, 35 are fastened on one side, via which the damping elements 36 to 39 30 vibrations are fed directly from the cylinder jacket. In addition, butt joints 11 are formed by shock absorbing pieces 40 to 43, which are connected to the damping elements 36 to 39, via which elastic shocks, advantageously supplied via the same path 33, are transmitted during the channel rollover and are fed into the system from the damping elements 36 to 39.

Die Einleitung der Anregung erfolgt vorzugsweise in Zylindermitte, die Stoßstellen sind vorzugsweise in Nähe der Mitte aber auch beliebig anzuordnen.The excitation is preferably initiated in the middle of the cylinder, but the joints are preferably to be arranged in the vicinity of the center, however, as desired.

Die Erfindung bietet somit die Möglichkeit, Absorber in Kombination mit Mitteln zur Aufnahme und Dämpfung des "elastischen Stoßes" von Biege-und Drehschwingungen anzuwenden bzw. zu nutzen, wobei jeweils die Absorber vorzugsweise in der Zylindermitte, wo der größte Ausschlag erfolgt, angeordnet sind und auch der" elastische Stoß" in der Zylindermitte dem Dämpfungssystem zugeleitet werden kann. Außerdem können, wie durch das Bezugszeichen 12 in Fig.l angedeutet, bei allen Ausführungsformen die Dämpfungselemente in Dämpfungsmaterialien, beispielsweise aufgeschäumte, elastische Materialien, eingebettet sein.The invention thus offers the possibility of using or using absorbers in combination with means for absorbing and damping the "elastic shock" of bending and torsional vibrations, the absorbers preferably being arranged in the middle of the cylinder, where the greatest deflection occurs also the "elastic shock" in the middle of the cylinder can be fed to the damping system. In addition, as indicated by reference number 12 in FIG. 1, the damping elements can be embedded in damping materials, for example foamed elastic materials, in all embodiments.
