Description
Die Erfindung betrifft eine Vorrichtung zur Korrektur
des Fan-Out-Effektes an Rollenrotationsdruckmaschinen
entsprechend dem Oberbegriff des Anspruches 1.The invention relates to a device for correction
the fan-out effect on web-fed rotary printing presses
according to the preamble of
Durch die DE 295 01 373 U1 ist eine gattungsgemäße
Vorrichtung bekannt, bei welcher zwischen dem zweiten
und dritten Doppeldruckwerk einer vier Doppeldruckwerke
aufweisenden Rotationsdruckmaschine zwei Bildstellrollen
angeordnet sind.
Diese Bildstellrollen sind frei drehbar an schwenkbaren
Hebeln gelagert.From DE 295 01 373 U1 a generic device is known in which two image setting rollers are arranged between the second and third double printing units of a rotary printing press having four double printing units.
These image rollers are freely rotatable on swiveling levers.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Korrektur des Fan-Out-Effektes an Rollenrotationsdruckmaschinen zu schaffen.The invention has for its object a Device for correcting the fan-out effect To create web-fed rotary printing presses.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale
des kennzeichnenden Teils des Anspruches 1 gelöst.This object is achieved by the features
of the characterizing part of
Die durch die Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß der Fan-Out-Effekt insbesondere bei Papierbahnen größerer Breite korrigiert werden kann, wie sie z. B. bei der Herstellung von Telefonbüchern verwendet werden. Durch die voneinander unabhängig an die Papierbahn anstellbaren Stell- und Gegenstellelemente ist es möglich, auch bei einseitig seitlichen Registerabweichungen gezielt Abhilfe zu schaffen.The advantages that can be achieved by the invention exist especially in that the fan-out effect in particular can be corrected for paper webs of greater width, as they e.g. B. in the production of telephone books be used. By being independent of each other the paper web adjustable positioning and Counter elements are possible, even with one-sided lateral register deviations specifically remedy create.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is in the Drawing shown and will be described in more detail below described.

Bei einer Rollenrotationsdruckmaschine ist die
erfindungsgemäße Vorrichtung zur Korrektur des
Fan-Out-Effektes zwischen dem zweiten und dritten
Druckwerk angeordnet. Dazu ist in zwei Seitengestellen
1; 2 auf einer linken Seite 3 einer vorgesehenen
Papierführung für eine die Druckwerke durchlaufenden
Papierbahn 4 eine Schwenkspindel 6 verdrehbar gelagert.
Sie nimmt drehfest eine Mehrzahl n, z. B. vier, jeweils
in einem Abstand a, z. B. einem Viertel einer Breite der
Papierbahn 4, angeordnete Schwenkhebel 11 mit je einem
Stellelement 7 bis 10, z. B. einer Blasdüse oder
Stellrolle auf. Die Schwenkhebel 11 enden in Gabeln 17,
welche jeweils die Stellelemente 7 bis 10 - z. B.
Sellrollen - drehbar aufnehmen. Die Schwenkspindel 6 ist
z. B. mittels eines seitengestellfesten Getriebemotors
12 verdrehbar, so daß die Stellrollen 7 bis 10 von einer
vom Papierweg der Papierbahn 4 nach links entfernten
Ruhestellung B (Fig. 1 und gestrichelte Darstellung
Fig. 2) in eine Arbeitsstellung C (gestrichelte
Darstellungen in Fig. 1 und 2) rechts neben den
Papierweg der Papierbahn 4 bringbar sind.For a web-fed rotary press, that is
Device according to the invention for correcting the
Fan-out effects between the second and third
Printing unit arranged. This is in two
Rechts neben dem vorgesehenen Papierweg der Papierbahn 4
sind eine Mehrzahl m, z. B. drei, in z. B. einem
gleichen Abstand a voneinander beabstandeter
Gegenstellelemente 14 bis 16, z. B. Gegenblasdüsen oder
Gegenstellrollen vorgesehen. Die Gegenstellelemente 14
bis 16 sind axial um einen Betrag kleiner a, z. B. a/2
zu den Stellelementen 7 bis 10 versetzt angeordnet.
Dabei sind die äußeren Gegenstellelemente 14; 16 jeweils
z. B. in einem Abstand a von einer der Seitenkanten 18;
19 der Papierbahn 4 bzw. von den Stirnseiten der
Gummizylinder angeordnet.To the right of the intended paper path of paper web 4
are a plurality m, z. B. three, in z. B. one
same distance a from each
Jede der Gegenstellelemente 14 bis 16 ist von einer
rechts von der Papierbahnführung vorgesehenen
Ruhestellung D ausgehend, einzeln in eine individuelle
Arbeitsstellung E bzw. F bzw. G bringbar. Die
Ruhestellung D kann jeweils rechts neben , auf oder
links neben dem vorgesehenen Papierbahnweg sein. Hierbei
wird schließlich jeweils die rechte Seite 13 der
Papierbahn 4 berührt (Fig. 2). Dazu ist z. B. für das
mittlere Gegenstellelement 15 eine in den
Seitengestellen 1; 2 gelagerte Schwenkspindel 21
vorgesehen, welche drehfest mit einem zweiten Ende eines
für das Gegenstellelement 15 vorgesehenen Schwenkhebels
20 verbunden ist.Each of the
Das jeweils erste Ende jedes Schwenkhebels 20 nimmt
jeweils das Gegenstellelement 14; 15; 16, z. B. als
Stellrolle ausgebildet auf. Die Stellrollen sind z. B.
mittels einer Gabel 17 drehbar gelagert. Die
Schwenkspindel 21 wird z. B. mittels eines
seitengestellfesten Getriebemotors 22 verschwenkbar
angetrieben.
Die rechten Schwenkhebel 20 für die äußeren
Gegenstellelemente 14; 16 sind auf Hohlwellen 23; 24
angeordnet. Die Hohlwellen 23; 24 sind auf der
Schwenkspindel 21 aufgefädelt. Jede Hohlwelle 23; 24 ist
an ihrem seitengestellnahen Ende drehfest mit einem
Zahnrad 26; 27 versehen, was jeweils mit einem Zahnrad
28; 29 eines Antriebsmotors 31; 32 kämmt.The respective first end of each

Die Funktionsweise der erfindungsgemäßen Vorrichtung ist
wie folgt. Wird eine infolge Papierfeuchtigkeit
(Fan-Out-Effekt) verbreiterte Papierbahn 4 in Richtung
der Gummizylinder 33; 34 des nächstfolgenden Druckwerkes
bewegt, so werden die Stellelemente 7 bis 10 mittels des
Getriebemotors 12 aus der Ruhestellung B zur
Arbeitsstellung C in Richtung der theoretischen
Papierbahnführung der Papierbahn 4 verschwenkt, bis die
Papierbahn 4 berührt wird. Die Gegenstellelemente 14 bis
16 werden ebenfalls über die Schwenkspindel 21 bzw. die
Hohlwellen 23; 24 mittels der Motoren 31; 22; 32 von
einer Ruhestellung D in Richtung des vorgesehenen
Papierbahnweges nach links bewegt - z. B. verschwenkt
oder verschoben -, bis die Papierbahn 4 berührt wird,
jeweils in eine Arbeitsstellung E bzw. F bzw. G.
Hierdurch werden in der Papierbahn 4 temporäre
Längsfalten 36 ausgebildet, die von Verschmälerung der
Papierbahn 4 in druckfreien Räumen ausgehen. Durch die
scheinbare Verschmälerung der Papierbahn 4 werden die
Auswirkungen des Fan-Out-Effektes korrigiert.The mode of operation of the device according to the invention is
as follows. Will be due to paper moisture
(Fan-out effect) widened paper web 4 in the direction
the
Bei einer größeren einseitigen seitlichen
Registerabweichung ist es möglich, durch die Wahl der
Tiefe des "Ineinandergreifens" der Gegenstellelemente
14, 15, 16 in den Bereich der Stellelemente 7 bis 10
einen Ausgleich zu schaffen.With a larger one-sided side
It is possible to change the register by choosing the
Depth of the "interlocking" of the
Der Schwenkwinkel der einzelnen Gegenstellelemente 14
bis 16 ist einzeln einstellbar. Es wäre möglich, die
Stellelemente 7 bis 10 einzeln zu verschwenken. Hierzu
wäre die gleiche Einrichtung wie für die
Gegenstellelemente 14 bis 16 vorzusehen.The swivel angle of the
Sämtliche Motoren 12; 22; 31; 32 sind mit ihrem Gehäuse
am Seitengestell 1 oder 2 verdrehfest angeordnet. An
jedem der genannten Motoren 12; 22; 31; 32 kann z. B.
ein nichtdargestellter Drehwinkel-Lagegeber angeordnet
sein, welcher die jeweilige Stellung der zugeordneten
Stellelemente 7 bis 10 bzw. Gegenstellelemente 14 bis 16
an einen Maschinenleitstand meldet.All motors 12; 22; 31; 32 are with their housing
arranged on the

der beschriebenen Schwenkbewegung geschehen. Auch sind
verschiebbare Schlitten, auf denen jeweils die
Stellelemente 7 bis 10 bzw. jeweils die
Gegenstellelemente 14 bis 16 einzeln oder
gemeinsam befestigt sind, geeignet. Der Antrieb der
