Description

  

  Vorrichtung zum Steuern von     Falzklappen,    Punkturen, Falzmessern und     dergl.     für Falzzylinder von Rotationsdruckmaschinen.    Die Erfindung betrifft eine     Vorrichtung     zum Steuern von Falzklappen,     Punkturen,     Falzmessern und dergleichen für Falzzylinder  von Rotationsdruckmaschinen, bei der von  Steuerkurven bewegte Stössel mit unter Fe  derdruck stehenden Hebeln -der Falzklappe  oder dergleichen über verstellbare Anschläge  zusammenarbeiten. Bei bekannten Vorrich  tungen dieser Art wird der Stössel, der den       Falzklappenhebel    steuert, in     achsialer    Rich  tung in einer Gleithülse geführt.

   Beim  Steuern dieses Stössels durch Steuerkurven  treten Stösse in Richtung senkrecht zur Längs  achse des Stössels auf. Diese sind um so stär  ker, je höher die Tourenzahl der Druckma  schine ist. Infolgedessen entstehen starke  Reibungskräfte innerhalb der Führungshülse.  Der Verschleiss ist sehr gross.  



  Mit der Erfindung sollen diese Nachteile  der bekannten Vorrichtung vermieden werden.  Dies wird bei einer Vorrichtung der oben    beschriebenen Art dadurch erreicht, dass die  auf der Steuerkurve laufende Rolle des Stössels  an einem schwingbaren, im Falzzylinder fest  gelagerten Hebel     angelenkt    ist, und dass der  verstellbare Anschlag mit dem Stössel über  ein Kugelgelenk verbunden ist.  



  Die Zeichnung zeigt ein Ausführungsbei  spiel des Erfindungsgegenstandes in     Seiten-          und    Vorderansicht. Es zeigen       Fig.    1 eine Vorderansicht,       Fig.    2 eine Seitenansicht mit hochge  klapptem Steuerarm 11 einer Falzklappe 1.  Die Falzklappe 1 wird in bekannter  Weise durch einen Steuerhebel 2 gesteuert,  der an seinem einen Ende eine Steuerrolle 3  trägt, die auf einer Steuerkurve 4 läuft. Die  Rolle 3 ist an einem schwingbaren; im Falz  zylinder fest gelagerten Hebel     ä        angelenkt.     Das andere Ende des Steuerhebels 2 ist als  Kugel 7 ausgebildet, die in einer mit Aussen  gewinde 8     versehenen    Hülse 9 gelagert ist.

        Diese Hülse 9 ist in den Steuerarm 11 ver  stellbar eingeschraubt, der mit der Falzklappe  1 ein Stück bildet und mit dieser lose dreh  bar auf der     Falzklappenspindel    12 sitzt. Die  Falzklappe 1 ist im übrigen normal ausge  bildet. Sie wird entgegen der Kraft einer  Feder 13 durch die Kurve 4 und Steuer  rolle 3 gesteuert. Der Hub der Falzklappe  lässt sich durch Verstellen der Hülse 9 in  dem Steuerarm<B>11</B> einstellen. Die Erfindung  kann in gleicher Weise zur Steuerung von  Punkturen, Falzmessern und dergleichen an  gewendet werden.



  Device for controlling folding jaws, punctures, folding knives and the like. For folding cylinders of rotary printing machines. The invention relates to a device for controlling folding jaws, punctures, folding knives and the like for folding cylinders of rotary printing presses, in which the plunger moved by control cams with levers under pressure - the folding jaw or the like work together via adjustable stops. In known Vorrich lines of this type, the plunger that controls the jaw lever is guided in the axial direction Rich in a sliding sleeve.

   When controlling this plunger by control cams, shocks occur in the direction perpendicular to the longitudinal axis of the plunger. The higher the number of revolutions of the printing press, the stronger these are. As a result, strong frictional forces arise within the guide sleeve. The wear is very great.



  The invention is intended to avoid these disadvantages of the known device. This is achieved in a device of the type described above in that the roller of the ram running on the cam is articulated to a swingable lever fixedly mounted in the folding cylinder and the adjustable stop is connected to the ram via a ball joint.



  The drawing shows a Ausführungsbei game of the subject invention in side and front view. 1 shows a front view, FIG. 2 shows a side view with the control arm 11 of a folding jaw 1 folded up. The folding jaw 1 is controlled in a known manner by a control lever 2, which carries a control roller 3 at one end, which is on a control cam 4 running. The roller 3 is on a swingable; in the folding cylinder firmly mounted lever articulated. The other end of the control lever 2 is designed as a ball 7 which is mounted in a sleeve 9 provided with an external thread 8.

        This sleeve 9 is screwed ver adjustably into the control arm 11, which forms a piece with the jaw 1 and sits loosely rotating bar on the jaw spindle 12 with this. The jaw 1 is otherwise normal forms. It is controlled against the force of a spring 13 by the curve 4 and 3 control. The stroke of the folding jaw can be adjusted by adjusting the sleeve 9 in the control arm 11. The invention can be used in the same way for controlling punctures, folding knives and the like.
