Description

Die Erfindung bezieht sich auf eine Walze für ein Farbwerk von Druckmaschinen mit einer drehfest in Lagerungen gelagerten Walzenachse und einem Walzenmantel, der drehbar auf der Walzenachse gelagert ist und so angetrieben wird, daß über Antriebsmittel, die innerhalb des Walzenmantels vorgesehen sind, eine axiale Hubbewegung auf den sich drehenden Walzenmantel übertragene wird.The invention relates to a roller for an inking unit of printing presses with a roller shaft mounted in a rotationally fixed manner in bearings and a roller shell which is rotatably mounted on the roller axis and is driven in such a way that an axial stroke movement occurs via drive means which are provided within the roller shell the rotating roller jacket is transmitted.

Die DE-OS 22 38 481 zeigt einen Antrieb für eine gleichzeitig dreh- sowie hin- und herbewegbare Verreibwalze an Druckmaschinen. Als Antriebsmittel wird hier ein Planetenradgetriebe benutzt, das in Verbindung mit einer Steuerkurve eine axiale Hubbewegung des Walzenmantels erzeugt. Das hier gezeigte Untersetzungsgetriebe weist eine maximale Untersetzung von 1:4 auf, so daß bei vier Umdrehungen der Walze ein Hub von beispielsweise 15 mm ausgeführt wird. Es hat sich aber gezeigt, daß bei Druckmaschinen mit hoher Leistung, z.B. bei 40 000 Plattenzylinderumdrehungen pro Stunde eine derartige Walze im Farbwerk 1 850 Umdrehungen pro Minute ausführen kann. Dies bedeutet, daß in der Minute 460, bzw. in der Sekunde etwa 7,5 Hubbewegungen ausgeführt werden müssen. Diese hohe Frequenz der Walzenbewegung verursacht einen erheblichen Verschleiß in den Antriebsmitteln und erzeugt zusätzlich Schwingungskräfte in der Maschine, die sich negativ auf das Druckergebnis auswirken. Bei der gegebenen Masse einer solchen Walze werden hierdurch die Seitengestelle der Maschine einer erheblichen Schlagbelastung ausgesetzt.DE-OS 22 38 481 shows a drive for a simultaneously rotating and reciprocating distributor roller on printing machines. A planetary gear mechanism is used here as the drive means, which in conjunction with a control cam generates an axial stroke movement of the roller shell. The reduction gear shown here has a maximum reduction of 1: 4, so that a stroke of, for example, 15 mm is carried out at four revolutions of the roller. However, it has been shown that in high-performance printing machines, e.g. at 40,000 plate cylinder revolutions per hour, such a roller can execute 1,850 revolutions per minute in the inking unit. This means that approximately 7.5 lifting movements must be carried out in the minute 460 or in the second. This high frequency of the roller movement causes considerable wear in the drive means and additionally generates vibrating forces in the machine, which have a negative effect on the printing result. Given the mass of such a roller, the side frames of the machine are thereby subjected to a considerable impact load.

Ausgehend von diesem Stand der Technik ist es die Aufgabe der Erfindung, ein Antriebsmittel für eine derartige Walze zu schaffen, mit dem ein wesentlich höheres Untersetzungsverhältnis erreicht wird, so daß die axiale Hubbewegung der Walze auch bei sehr hohen Drehzahlen nicht zu einer schlagförmigen Bewegungsumkehr führt und der Bewegungsablauf der Walze in Axialrichtung wesentlich verlangsamt wird.Based on this prior art, it is the object of the invention to provide a drive means for such a roller with which a much higher one Reduction ratio is reached so that the axial stroke movement of the roller does not lead to a sudden reversal of movement even at very high speeds and the movement of the roller in the axial direction is considerably slowed down.

Gemäß der Erfindung wird die Aufgabe dadurch gelöst, daß als Antriebsmittel eine Schwinge vorgesehen ist, die über einen von dem Walzenmantel angetriebenen Exzenter quer zur Längsachse der Walze eine Pendelbewegung ausführt, daß die Pendelbewegung sodann über einen Freilauf als Drehbewegung auf eine Kurve übertragen wird, die den Walzenmantel bei seiner Drehbewegung axial verschiebt. Mit diesen Antriebsmitteln für die Axialbewegung ist z.B. eine Untersetzung möglich, bei der eine Hubbewegung der Walze bei 31,4 Umdrehungen ausgeführt wird. Hierbei wird ca. eine Verreibebewegung je Sekunde bei 40 000 Zylinderumdrehungen pro Stunde ausgeführt, so daß die Antriebskräfte und somit der Verschleiß sehr gering sein können und hierdurch keinerlei Schwingungen auf die tragenden Teile der Maschine übertragen werden. Bei dieser Lösung können weiterhin robuste Bauteile Verwendung finden, so daß ein störungsfreier Lauf gewährleistet ist und durch die Schwingungsfreiheit die Präzision des Druckvorganges erhöht werden kann.According to the invention the object is achieved in that a rocker is provided as the drive means, which carries out a pendulum movement transversely to the longitudinal axis of the roller via an eccentric driven by the roller shell, that the pendulum movement is then transmitted via a freewheel as a rotary movement to a curve, which axially shifts the roller shell during its rotational movement. With these drive means for the axial movement e.g. a reduction possible, in which a lifting movement of the roller is carried out at 31.4 revolutions. In this case, approximately one rubbing movement per second is carried out at 40,000 cylinder revolutions per hour, so that the driving forces and thus the wear can be very low and as a result no vibrations are transmitted to the load-bearing parts of the machine. With this solution, robust components can continue to be used, so that trouble-free operation is ensured and the precision of the printing process can be increased by the absence of vibrations.

Eine vorteilhafte Ausgestaltung der Erfindung ist im Unteranspruch wiedergegeben. Diese Ausgestaltung der Walze ist dadurch gekennzeichnet, daß die Schwinge auf einem Lagerbolzen pendelnd gelagert ist, der in einem nicht drehenden, auf der Walzenachse befestigten Lagerkörper angeordnet ist, daß die Schwinge zwei sich diametral gegenüberliegende Kugellager trägt, deren Achsen parallel zur Walzenachse verlaufen, die an einer exzentrisch zur Walzenachse im Walzenmantel angeordneten und mit diesem drehenden, als Exzenter wirkenden Abrollfläche anlegen und von dieser eine Pendelbewegung auf die Schwinge übertragen und daß die Pendelbewegung von der Schwinge über einen Verbindungszapfen auf einen drehbar auf der Walzenachse gelagerten Drehkörper übertragen wird, der mit einem Freilauf zusammenwirkt, derart, daß die in einer Drehrichtung erzeugten, impulsförmigen Drehbewegungen eine auf der Walzenachse drehfest gelagerten Kurve mit axialem Hub antreiben, in der Kurvenrollen vorgesehen sind, die den Hub über einen Lagerkörper und ein Kugellager auf den Walzenmantel übertragen.An advantageous embodiment of the invention is given in the subclaim. This configuration of the roller is characterized in that the rocker is pivotally mounted on a bearing pin which is arranged in a non-rotating bearing body fixed on the roller axis, that the rocker carries two diametrically opposed ball bearings, the axes of which run parallel to the roller axis, which on an eccentrically arranged to the roll axis in the roll shell and rotating with this, acting as an eccentric rolling surface and from this a pendulum movement is transmitted to the rocker and that the pendulum movement is transmitted from the rocker via a connecting pin to a rotatably mounted rotating body which interacts with a freewheel, in such a way that the pulsed rotary movements generated in one direction of rotation are one on the roll axis Drive a non-rotatably supported curve with an axial stroke, in which cam rollers are provided, which transmit the stroke to the roller shell via a bearing body and a ball bearing.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen schematisch dargestellt. Es zeigt:

  • Fig. 1 einen Längsschnitt durch die Walze.
  • Fig. 2 einen Querschnitt gemäß 2.2.
An embodiment of the invention is shown schematically in the drawings. It shows:
  • Fig. 1 shows a longitudinal section through the roller.
  • 2 shows a cross section according to 2.2.

Die in Fig. 1 wiedergegebene Walze 1 ist auf einer Walzenachse 2 gelagert, die drehfest in Lagerungen 3 befestigt ist, wobei diese z.B. an einem nicht dargestellten Maschinenseitengestell angeordnet sein können. Der Walzenmantel 4 der Walze 1 ist über Lagerhalter 5, 6 und Nadellager 7 auf der Walzenachse 2 drehbar und längsverschiebbar gelagert. Der Walzenmantel 4 im gezeigten Ausführungsbeispiel kann über Reibschluß von einer benachbarten Walze oder einem Zylinder angetrieben werden.The roller 1 shown in Fig. 1 is mounted on a roller axis 2, which is rotatably fixed in bearings 3, these e.g. can be arranged on a machine side frame, not shown. The roll shell 4 of the roll 1 is rotatably and longitudinally displaceably supported on the roll axis 2 by means of bearing holders 5, 6 and needle bearings 7. The roller shell 4 in the embodiment shown can be driven by friction from an adjacent roller or a cylinder.

Als Antriebsmittel für die axiale Hubbewegung des Walzenmantels 4 ist innerhalb desselben eine Schwinge 8 vorgesehen, die auf einem Lagerbolzen 9 pendelnd gelagert ist. Der Lagerbolzen 9 ist in einem nicht drehenden, auf der Walzenachse 2 befestigen Lagerkörper 10 angeordnet, der z.B. auf der Walzenachse verklemmt sein kann. Im gezeigten Ausführungsbeispiel ist die Schwinge 8 über Nadellager 11 auf dem Lagerbolzen 9 gelagert. An der Schwinge 8 sind diametral gegenüberliegend zwei Kugellager 12 auf Bolzen 13 gelagert, deren Achsen parallel zur Walzenachse 2 verlaufen. Die beiden Kugellager 12 rollen in einem Exzenter 14 ab, der aus einer exzentrisch zur Walzenachse 2 angeordneten Abrollfläche 15 besteht, die im gezeigten Ausführungsbeispiel an einer büchsenförmigen Verlängerung 16 des Lagerhalters 5 vorgesehen ist und die sich gemeinsam mit dem Walzenmantel 4 dreht. Wie in Fig. 2 wiedergegeben beträgt die Pendelbewegung z.B. 2 mm, wenn die Exzentrizität der Abrollfläche 15 1 mm beträgt. In diesem Falle rollen die beiden Kugellager 12 nahezu spielfrei an der Abrollfläche 15 ab und bewegen die Schwinge 8 um den Lagerbolzen 9 herum pendelnd hin und her.As a drive means for the axial lifting movement of the roll shell 4, a rocker 8 is provided within the latter, which is mounted on a bearing pin 9 in an oscillating manner. The bearing pin 9 is arranged in a non-rotating bearing body 10 which is fastened on the roller axis 2 and which can be jammed, for example, on the roller axis. In the exemplary embodiment shown, the rocker 8 is on via needle bearings 11 the bearing pin 9 stored. On the rocker 8 diametrically opposite two ball bearings 12 are mounted on bolts 13, the axes of which run parallel to the roller axis 2. The two ball bearings 12 roll in an eccentric 14 which consists of a rolling surface 15 arranged eccentrically to the roller axis 2, which in the exemplary embodiment shown is provided on a sleeve-shaped extension 16 of the bearing holder 5 and which rotates together with the roller shell 4. As shown in FIG. 2, the pendulum movement is, for example, 2 mm if the eccentricity of the rolling surface 15 is 1 mm. In this case, the two ball bearings 12 roll off the rolling surface 15 almost without play and move the rocker 8 back and forth oscillating around the bearing pin 9.

Gegenüber dem Lagerbolzen 9 ist in der Schwinge 8 ein Verbindungszapfen 17 befestigt, der in einen auf der Walzenachse 2 drehbar gelagerten Drehkörper 18 eingreift. Der Drehkörper 18 ist über Nadellager 19 drehbar gelagert und gegen eine Axialbewegung abgesichert. Auf dem Drehkörper ist ein Freilauf 20 vorgesehen, der als Hülsenfreilauf ausgebildet ist und beiderseits Wälzlager 20a aufweist und der die Drehbewegung in einer Drehrichtung, die von der Schwinge 8 auf den Drehkörper 18 übertragen wird, impulsförmig auf eine Kurve 21 überträgt, die den Freilauf 20 umfaßt. Die Kurve 21 ist über Nadellager 22 ebenfalls auf der Walzenachse 2 drehbar gelagert. Gemeinsam mit dem Drehkörper 18 ist die Kurve 21 über Sicherungsringe 23 axial fixiert. Die Kurvenbahn 24 kann als Sinuskurve ausgebildet sein mit einem Hub von beispielsweise 15 mm. In der Kurvenbahn 24 bewegen sich zwei Kurvenrollen 25, die durch die Form der Kurve eine Axialbewegung übermittelt bekommen.A connecting pin 17 is fastened in the rocker 8 opposite the bearing pin 9 and engages in a rotating body 18 rotatably mounted on the roller axis 2. The rotating body 18 is rotatably supported by needle bearings 19 and secured against axial movement. On the rotating body, a freewheel 20 is provided, which is designed as a sleeve freewheel and has roller bearings 20a on both sides and which transmits the rotational movement in a direction of rotation, which is transmitted from the rocker 8 to the rotating body 18, in a pulse-like manner on a curve 21, which the freewheel 20 includes. The curve 21 is also rotatably mounted on the roller axis 2 via needle bearings 22. Together with the rotating body 18, the curve 21 is axially fixed via locking rings 23. The cam track 24 can be designed as a sine curve with a stroke of 15 mm, for example. Two cam rollers 25 move in the cam track 24 and are given an axial movement by the shape of the cam.

Die beiden Kurvenrollen 25 sind an dem Arm 26 eines Lagerkörpers 27 befestigt, der wiederum über Büchsen 28 längsverschiebbar auf der Walzenachse 2 gelagert ist. Zwischen Lagerkörper 27 und Walzenmantel 4 ist ein Kugellager 29 vorgesehen, das die Hubbewegung von dem Lagerkörper 27 auf den Walzenmantel 4 überträgt. Hierbei ist der Lagerkörper 27 durch ein Gabelstück 30 gegenüber der Walzenachse 2 drehgesichert, wobei das Gabelstück 30 die Längsbewegung des Lagerkörpers 27 zuläßt.The two cam rollers 25 are attached to the arm 26 of a bearing body 27, which in turn is mounted on the roller axis 2 so as to be longitudinally displaceable via bushings 28. Between the bearing body 27 and the roller shell 4, a ball bearing 29 is provided, which transmits the lifting movement from the bearing body 27 to the roller shell 4. Here, the bearing body 27 is secured against rotation by a fork piece 30 with respect to the roller axis 2, the fork piece 30 permitting the longitudinal movement of the bearing body 27.

Durch die exzentrische Ausbildung der Abrollfläche 15 wird die Schwinge 8 um etwa 2 mm sinusförmig in Schwingbewegung versetzt, so daß die auf den Drehkörper 18 übertragene Drehbewegung sehr langsam und stoßfrei erfolgt. Durch die ebenfalls sinusförmig ausgebildete Kurvenbahn 24 ist auch die weitere Übertragung der Bewegung auf den Walzenmantel 4 völlig stoßfrei, so daß dieser eine sehr ruhige Hin- und Herbewegung ausführt. Selbstverständlich kann die Exzentrizität der Abrollfläche 15 und der Hub der Kurvenbahn 24 an die jeweiligen Erfordernisse angepaßt werden.Due to the eccentric design of the rolling surface 15, the rocker 8 is set in a sinusoidal oscillating movement by approximately 2 mm, so that the rotational movement transmitted to the rotating body 18 takes place very slowly and smoothly. Due to the likewise sinusoidal curved path 24, the further transmission of the movement to the roller jacket 4 is completely shock-free, so that the latter performs a very quiet reciprocating movement. Of course, the eccentricity of the rolling surface 15 and the stroke of the cam track 24 can be adapted to the respective requirements.
