Description

Die Erfindung betrifft einen Sammelzylinder für Punkturfalzapparate von Rotationsdruckmaschinen gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to a collecting cylinder for pin folder of rotary printing presses according to the preamble of claim 1.

Im Durchmesser veränderbare Sammelzylinder sind in verschiedenen Ausführungen allgemein bekannt. Sie sind für die Papierzugregelung bei verschieden dicken Sammelprodukten notwendig.Diameter-adjustable collecting cylinders are generally known in various designs. They are necessary for the paper tension control for collectors' products of different thicknesses.

Sammelzylinder mit von Punkturträger zu Punkturträger reichenden Umfangselementen sind sowohl durch die DE-PS 16 11 330 als auch durch die CH-PS 417 646 bekannt geworden. Die Verstellung der Umfangselemente erfolgt jedoch weder bei der einen noch bei der andern Ausführung über Exzenterwellen.Collection cylinders with circumferential elements extending from puncture carriers to puncture carriers are known both from DE-PS 16 11 330 and from CH-PS 417 646. However, the circumferential elements are not adjusted either with eccentric shafts in either one or the other.

Eine dem Oberbegriff entsprechende Ausführung ist aber aus der Praxis bekannt. Hier werden die Umfangselemente gruppenweise an ihren beiden Enden auf Exzenterwellen gelagert, durch welche eine radiale Verstellung der Umfangselemente ermöglicht wird. Damit diese Verstellung bei jeder Umfangselementgruppe immer gleichzeitig erfolgt, trägt jede Exzenterwelle ein Ritzel, das mit einem zentrisch zum Sammelzylinder drehbar gelagerten Stirnrad im Eingriff steht (siehe auch DE-PS 20 40 494). Durch Verändern der Winkellage dieses Stirnrades zum Sammelzylinder wird somit zwangsläufig auch die radiale Lage der Umfangssegmente und dadurch der aktive Durchmesser des Sammelzylinders verändert.An embodiment corresponding to the preamble is known from practice. Here, the peripheral elements are mounted in groups at their two ends on eccentric shafts, by means of which a radial adjustment of the peripheral elements is made possible. So that this adjustment is always carried out at the same time for each circumferential element group, each eccentric shaft has a pinion which is in engagement with a spur gear which is rotatably mounted centrally to the collecting cylinder (see also DE-PS 20 40 494). By changing the angular position of this spur gear relative to the collecting cylinder, the radial position of the peripheral segments and thus the active diameter of the collecting cylinder are inevitably changed.

Die obenerwähnten Ausführungen haben den Nachteil, dass die Umfangssegmente die Zugänglichkeit zu den Innenteilen des Sammelzylinders sehr erschweren oder sogar verhindern, so dass sie z.B. zum Auswechseln von Falzmessern vorerst aus dem ohnehin im Falzapparat nur bedingt zugänglichen Sammelzylinder ausgebaut werden müssen, wobei bei der Wiedermontage sehr genau auf die Exzenterwellenstellung geachtet werden muss.The above-mentioned designs have the disadvantage that the peripheral segments make access to the inner parts of the collecting cylinder very difficult or even impossible, so that they e.g. For the replacement of folding knives, the collecting cylinder, which is only partially accessible in the folder, has to be removed for the time being, with very careful attention being paid to the eccentric shaft position during reassembly.

Ein weiterer Nachteil weist die erwähnte Zahnradverbindung auf, die bei lang dauernder gleicher Einstellung des Sammelzylinderdurchmessers durch Papierstaub etc. derart verschmutzt werden kann, dass sie bei einer nachfolgenden Verstellung zum Klemmen kommt.Another disadvantage has the gear connection mentioned, which can be soiled by paper dust etc. if the same setting of the collecting cylinder diameter is maintained over a long period of time, so that it comes to a jam during a subsequent adjustment.

Der Erfindung liegt die Aufgabe zugrunde, einen die aufgeführten Nachteile vermeidenden Sammelzylinder zu schaffen.The invention has for its object to provide a collection cylinder avoiding the disadvantages listed.

Die Aufgabe wird erfindungsgemäss dadurch gelöst, dass mindestens eine Exzenterwelle jeder Umfangssegmentgruppe radial ausschwenkbar im Sammelzylinderkörper gelagert ist.The object is achieved according to the invention in that at least one eccentric shaft of each circumferential segment group is mounted in the collecting cylinder body so that it can be swung out radially.

Durch die erfindungsgemässe Massnahme können die Innenteile des Sammelzylinders praktisch frei zugänglich gemacht werden. Eine weitere Massnahme erlaubt das Ausschwenken irgendeiner Umfangselementgruppe, ohne dass dabei der Stellantrieb ihrer Exzenterwellen gelöst werden muss.The measures according to the invention make the inner parts of the collecting cylinder practically freely accessible. Another measure allows any circumferential element group to be swung out without having to release the actuator of their eccentric shafts.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es zeigt:

Fig. 2

Fig. 3
eine Ansicht eines Sammelzylinders mit einem Schnitt durch eine ausschwenkbar gelagerte Exzenterwelle
Ein Sammelzylinder 1 ist mit in bekannter Weise gesteuerten Punkturen 2 und Falzmessern 3 ausgerüstet. Am Umfang des Sammelzylinders 1 sind jeweils zwischen zwei Punkturträgern 4 gruppenweise im Abstand nebeneinander liegende Umfangssegmente 5 angeordnet, die an ihren beiden Enden auf Exzenterwellen 6 gelagert sind. Mindestens eine Exzenterwelle 6 jeder Umfangssegmentgruppe 5' ist beidseitig in Lagern 7 geführt, die in Schlitzen 8 positionsgerecht fixierbar, z.B. durch Schrauben 9 oder andere bekannte Mittel, untergebracht sind. Durch das Lösen dieser Fixierungen ist jede dermassen gelagerte Exzenterwelle 6 und damit ihre zugehörige Umfangssegmentgruppe 5 von Hand radial ausschwenkbar.In the drawing, an embodiment of the invention is shown. It shows:
Fig. 1
a cross section through a collecting cylinder with a pivoted peripheral element group
Fig. 2
the actuator side of a collection cylinder
Fig. 3
a view of a collecting cylinder with a section through a pivotally mounted eccentric shaft
A collecting cylinder 1 is equipped with punctures 2 and folding knives 3 controlled in a known manner. On the circumference of the collecting cylinder 1, circumferential segments 5 are arranged in groups at a distance from one another between two puncture carriers 4 and are supported on eccentric shafts 6 at their two ends. At least one eccentric shaft 6 of each circumferential segment group 5 'is guided on both sides in bearings 7 which can be fixed in position 8 in slots 8, for example by screws 9 or other known means. By releasing these fixings, each eccentric shaft 6 mounted in this way and thus its associated circumferential segment group 5 can be swung out radially by hand.

Auf dem einen Ende jeder Exzenterwelle 6 ist ein Stellhebel 10 fest montiert, der mittels einer Schubstange 11 gelenkig mit einer Stellscheibe 12 verbunden ist. Die Stellscheibe 12 ihrerseits ist zentrisch zum Sammelzylinder 1, z.B. auf der Sammelzylinderachse 13 verdrehbar gelagert und entweder mit einer nicht gezeichneten, bekannten mechanischen Fernverstellung verbunden oder, bei einer einfachen Ausführung für Handverstellung, mit einer geeigneten Fixiervorrichtung versehen.On one end of each eccentric shaft 6, an adjusting lever 10 is fixedly mounted, which is connected in an articulated manner to an adjusting disk 12 by means of a push rod 11. The adjusting disc 12 is in turn centered on the collecting cylinder 1, e.g. mounted rotatably on the collecting cylinder axis 13 and either connected to a known mechanical remote adjustment (not shown) or, in the case of a simple version for manual adjustment, provided with a suitable fixing device.

Zum Zweck der Handverstellung ist das andere Ende jeder Exzenterwelle 6 beispielsweise mit einem Sechskant 14 oder dgl. versehen, auf das ein übliches Drehwerkzeug aufsteckbar ist.For the purpose of manual adjustment, the other end of each eccentric shaft 6 is provided, for example, with a hexagon 14 or the like, onto which a conventional turning tool can be attached.
