Vorrichtung ein schonendes, verschleißarmes Einkuppeln
während eines steuerbaren Einkuppelvorganges erreicht,
da zwei, sich relativ zueinander drehende
Kupplungsscheiben im Vergleich zum eingekuppelten
Zustand mit reduzierter Kraft aufeinander gepreßt
werden. Die zwei in einem Arbeitszylinder auftretenden
Drücke werden mittels eines Druckschalters gemessen und
zur Anzeige des Kupplungszustandes verwendet. Dieser
Druckschalter kann in der Zuleitung des Arbeitszylinders

Menge von Druckmittel bei geöffneten Steuerventil ins
Freie abführend dosiert und gleichzeitig als Führung für
den Steuerkolben dient.Advantageously, the device according to the invention achieves a gentle, low-wear engagement during a controllable engagement process, since two clutch disks rotating relative to one another are pressed against one another with reduced force compared to the engaged state.

Ein Zylinder einer Rotationsdruckmaschine ist an einem
Zylinderzapfen 1 mittels einer schaltbaren Kupplung 2
mit einem Antriebszahnrad 3 verbindbar. Diese schaltbare
Kupplung 2 besteht aus einer ersten 6 und zweiten 4,
jeweils ringförmigen Kupplungsscheibe, die jeweils an
ihren gegenüberliegenden Planseiten mit einer
Stirnverzahnung 7, 8 versehen sind. Die
Stirnverzahnungen 7, 8 sind derart aufeinander angepaßt,
daß die Kupplung 2 nur in einer einzigen Stellung, in
der die beiden Kupplungsscheiben 4, 6 eindeutig
zueinander stehen, einkuppeln kann, d. h. die Kupplung 2
ist als Eindeutigkeitskupplung ausgeführt. Dazu kann die
eine Kupplungsscheibe 4 mit einem oder mehreren sich von
den übrigen Zähnen der Stirnverzahnung 7, 8
unterscheidenden, beispielsweise breiteren Zahn bzw.
Zähnen und die andere, zugehörige Kupplungsscheibe 6 mit
darauf angepaßten Zahnlücken versehen sein. Eine der
beiden Kupplungsscheiben 4, 6 ist starr mit dem
Zylinderzapfen 1 verbunden. Im vorliegenden Beispiel
sind die linke, einem Zylinderballen nächstliegende
Kupplungsscheibe 4 und ein Zahnrad 9 zum Antrieb
weiterer nichtdargestellter Zylinder oder eines
Farbwerkes mittels einer Paßfeder 11 auf dem
Zylinderzapfen 1 befestigt. Der Zylinder ist mit der
Kupplungsscheibe 4 und dem Zahnrad 9 zur
Seitenregistereinstellung axial verschiebbar.
Die rechte Kupplungsscheibe 6 ist drehsteif, aber axial
verschiebbar mit dem Antriebszahnrad 3 verbunden. Hierzu
weist die Kupplungsscheibe 6 an ihrem Umfang eine
Außenverzahnung 12 mit einer Breite b12, z. B.
b12 = 18 mm, auf, die in eine in das Antriebszahnrad 3
eingebrachte Innenverzahnung 13 mit einer Breite b13,
z. B. b13 = 40 mm, eingreift. Das Antriebszahnrad 3 ist
an einer Nabe 14 befestigt. Diese Nabe 14 weist eine auf
den Zylinderzapfen 1 angepaßte Bohrung 16 auf, so daß
die Nabe 14 mit dem Antriebszahnrad 3 auf dem
Zylinderzapfen 1 drehbar und axial verschiebbar gelagert
ist. Die axiale, zur Umfangsregistereinsteilung dienende
Verschiebung erfolgt mittels einer im Zylinderzapfen 1
gelagerten, mit einer nichtdargestellten
Registereinstelleinrichtung verbundenen, axial
verschiebbaren Spindel 17, die mit dem Antriebszahnrad 3
über eine Scheibe 18 starr verbunden ist.A cylinder of a rotary printing press is on one
Cylinder pin 1 by means of a switchable clutch 2
connectable with a
An dieser Nabe 14 des Antriebszahnrades 3 ist ein
Arbeitszylinder 19 angeflanscht. Der Arbeitszylinder 19
weist einen ringförmigen, axial verschiebbaren Kolben 21
auf, der auf zylinderförmige Druckstücke 22 wirkt. Eine
Mehrzahl, z. B. 8 Stück, dieser Druckstücke 22 sind
gleichmäßig in Umfangsrichtung in Bohrungen 23 der Nabe
14 gelagert und mittels Schrauben 24 mit der rechten
Kupplungsscheibe 6 verbunden. Die Druckstücke 22 sind an
ihrem mit dem Kolben 21 zusammenwirkenden Ende mit einem
Bund 26 versehen. Zwischen diesem Bund 26 und der Nabe
14 sind auf den Druckstücken 22 Druckfedern 27
angeordnet.
Mit dem Arbeitszylinder 19 ist eine Dreheinführung 28
verbunden, die über eine Bohrung 29 einen Zylinderraum
31 mit Druckmittel versorgt. In einer Zuleitung 32 zu
der Dreheinführung 28 ist ein nichtdargestellter, z. B.
elektro-pneumatischer Druckschalter vorgesehen, dessen
Schaltpunkt beispielsweise auf 5 bar eingestellt ist.
Der Zylinderraum 31 ist über eine in den Kolben 21
eingebrachte Bohrung 33 mit einer Leitung 34 verbunden,
die wiederum an ein Steuerventil 36 anschließt. Das
Steuerventil 36 ist fest in der rechten Kupplungsscheibe
6 montiert und wirkt zeitweise mit der linken
Kupplungsscheibe 4 zusammen.
Dieses Steuerventil 36 besteht im wesentlichen aus einem
Gehäuse 37, einem Steuerkolben 38, einer Druckfeder 39
und einer Druckhülse 41. Das Gehäuse 37 ist stirnseitig
mit einer Bohrung 42, an deren einem Ende die Leitung 34
angeschlossen ist und deren zweites Ende eine
konusartige Senkung 43 aufweist, versehen. An diese
Bohrung 42 schließt in Längsrichtung eine zweite,
durchgehende Bohrung 44 mit einem Innendurchmesser d44,
z. B. d44 = 6,5 mm an. In dieser Bohrung 44 ist der
Steuerkolben 38 in Längsrichtung beweglich angeordnet.A working
A rotary lead-in 28 is connected to the working
This
Dieser Steuerkolben 38 weist an seinem ersten Ende einen
konusartigen Dichtkopf 46 auf, wobei dieser konusartige
Dichtkopf 46 mit einer ringförmig umlaufenden Nut 47 zur
Aufnahme eines Dichtringes 48, z. B. eines O-Ringes,
versehen ist. An diesen konusartigen Dichtkopf 46
schließt sich ein Schaft 49 mit einem Durchmesser d49,
z. B. d49 = 3 mm, an, der zur Aufnahme der Druckfeder 39
dient. Diese Druckfeder 39 drückt mit ihrem ersten Ende
gegen eine Unterseite 51 des Dichtkopfes 46 und mit
ihrem zweiten Ende gegen eine obere Stirnfläche 52 der
Druckhülse 41. Die Druckhülse 41 weist eine Bohrung 53
mit einem Durchmesser d53, z. B. d53 = 3,5 mm, in
Längsrichtung verlaufend auf. Die Bohrung 53 der
Druckhülse 41 und der Schaft 49 des Steuerkolbens 38
bilden einen Ringspalt 54. Ein Außendurchmesser
D41, z. B. D41 = 6,4 mm, der Druckhülse 41 ist im
Bereich eines Absatzes 56 auf den Innendurchmesser d44
des Gehäuses 37 derart angepaßt, daß die Druckhülse 41
in Längsrichtung verschiebbar gelagert ist. Mit einer
unteren, als Anschlag dienenden Stirnfläche 57 des
Absatzes 56 wirkt zeitweise eine Stirnfläche 58 einer
Anschlaghülse 59 zusammen, die zum Begrenzen des Weges
der Druckhülse 41 in der Bohrung 44 des Gehäuses 37
befestigt ist. Eine untere Stirnfläche 61 der Druckhülse
41 ragt aus dem Gehäuse 37 heraus. Dieses Steuerventil
36 ist so in der rechten Kupplungsscheibe 6 montiert,
daß im eingekuppelten Zustand die Stirnfläche 61 der
Druckhülse 41 mit der linken Kupplungshälfte 4
zusammenwirkt.This
Die Funktionsweise der erfindungsgemäßen Vorrichtung ist folgendermaßen:The mode of operation of the device according to the invention is as follows:
In einer ausgerückten Stellung der Kupplung 2 ist der
Zylinderraum 31 des Arbeitszylinders 19 nicht mit
Druckmittel beaufschlagt. Dadurch drücken die
Druckfedern 27 über die Druckstücke 22 den Kolben 21
nach rechts und ziehen gleichzeitig die rechte
Kupplungsscheibe 6 entlang der Innenverzahnung 13 des
Antriebsrades 3 aus der Stirnverzahnung 7 der linken
Kupplungsscheibe 4, bis beide Kupplungsscheiben 4, 6
außer Eingriff sind. Dabei gerät die Stirnfläche 61 der
Druckhülse 41 des Steuerventils 36 mit der linken
Kupplungsscheibe 4 außer Kontakt, so daß die Druckhülse
41 von der Druckfeder 39 gegen die Anschlaghülse 59
gedrückt und die Druckfeder 39 entspannt wird.In a disengaged position of the clutch 2
Zum Einkuppeln des Zylinders an das Antriebsrad 3 wird
dem Arbeitszylinder 19 über die Dreheinführung 28
Druckmittel zugeführt. Dieses Druckmittel strömt durch
die Leitung 34 auch zu dem Steuerventil 36 und drückt
durch den sich aufbauenden Druck den konusartigen
Dichtkopf 46 des Steuerkolbens 38 von der konusartigen
Senkung 43 weg, so daß durch sich einen dadurch
ergebenden Ringspalt Druckmittel fließt. Dieses
Druckmittel entweicht durch den Ringspalt 54 von
Steuerkolben 38 und Druckhülse 41 ins Freie. Dieser
Ringspalt 54 und die dem Arbeitszylinder 19 zugeführte
Menge von Druckmittel sind derart aufeinander
abgestimmt, so daß sich ein Druck im Arbeitszylinder 19
aufbaut und die beiden Kupplungsscheiben 4, 6 mittels
der Druckstücke 22 aufeinander gedrückt werden. Eine
Größe des Druckes p1, z. B. p1 = 3,5 bar, ist bei
geöffneten Steuerventil 36 während des
Einkuppelvorganges kleiner als ein Enddruck p2,
z. B. p2 = 6 bar, bei geschlossenen Steuerventil 36,
d.h. im eingekuppelten Zustand. Die Größe des Drucks p1
beträgt vorzugsweise 1/3 bis 2/3 des Enddrucks p2. Dazu
wird die zugeführte Menge des Druckmittels mittels z. B.
einer nichtdargestellten Drossel dosiert.
Der Zylinder wird nun mittels eines nichtdargestellten
Hilfsantriebes gedreht, so daß sich die beiden
aufeinander gepreßten Kupplungsscheiben 4, 6 relativ
zueinander verdrehen. Die Druckhülse 41 des
Steuerventiles 36 berührt dabei nicht die linke
Kupplungsscheibe 4 und das Steuerventil 36 bleibt
geöffnet. Erreichen nun die beiden Kupplungsscheiben 4,
6 ihre eindeutig zugeordnete Stellung, rasten die beiden
Stirnverzahnungen 7, 8 ineinander ein. Die linke
Kupplungsscheibe 4 drückt nun gegen die Druckhülse 41
des Steuerventils 36 und diese wiederum spannt die damit
zusammenwirkende Druckfeder 39. Diese gespannte
Druckfeder 39, deren Druckkraft größer als eine auf den
Steuerkolben 38 wirkende Kraft infolge des Druckmittels
ist, drückt den Steuerkolben 38 gegen die Senkung 43 des
Gehäuses 37 und der Ringspalt zwischen Dichtkopf 46 und
Senkung 43 wird so geschlossen. Das Steuerventil 36 ist
damit geschlossen, es kann kein Druckmittel mehr
entweichen, weswegen sich der Enddruck p2 im
Arbeitszylinder 19 einstellt. Der Druckschalter in der
Zuleitung 32 zu der Dreheinführung 28 schaltet durch den
Druckanstieg und gibt ein elektrisches Signal, das zur
weiteren Maschinensteuerung verwendet wird.In order to couple the cylinder to the
The cylinder is now rotated by means of an auxiliary drive, not shown, so that the two
