Ein Zylinder 1 einer Rotationsdruckmaschine ist zur
Aufnahme von biegsamen Platten 2 mit axial verlaufenden,
sich von einer Mantelfläche 3 des Zylinders 1 in ein
Inneres des Zylinders 1 erstreckenden
Schlitzbefestigungen 4 versehen. Bei der Platte 2 einer
Dicke d2, z. B. 0,3 mm, handelt es sich vorzugsweise um
Druckplatten, es können aber auch beispielsweise Platten
2 mit aufgebrachten Gummitüchern verwendet werden. Die
Platte 2 ist am Anfang 6 und am Ende 7 jeweils
mit einer Einhängeabkantung 8, 9 versehen. Die
Einhängeabkantungen 8, 9 werden von jeweils einem
Einhängeschenkel 11, 12, der mit der planliegenden
Platte 2 einen Winkel Alpha, z. B. 45°, am Anfang 6
und einen Winkel Beta, z. B. 135°, am Ende 7
einschließt, gebildet. Der Winkel Alpha
am Anfang 6 ist spitz, während der Winkel Beta am
Ende 7 stumpf ist.A
Die Schlitzbefestigung 4 ist im vorliegenden Beispiel
als ein axial verlaufender, sich über eine Länge des
Zylinders 1 erstreckender, von der Mantelfläche 3 des
Zylinders 1 in das Innere des Zylinders 1 ragender
Schlitz ausgeführt, dessen Breite b4 mindestens der
doppelten Dicke d2 der Platte 2 entspricht und somit die
Einhängeabkantungen 8, 9 am Anfang 6 und Ende
7 der Platte 2 gemeinsam aufnimmt.
Natürlich ist es auch möglich Schlitzbefestigungen 4 zu
verwenden, die für Anfang 6 und Ende 7
getrennt sind. Auch können zur Aufnahme mehrerer Platten
2 am Umfang bzw. entlang der Länge des Zylinders 1
mehrere Schlitzbefestigungen 4 vorgesehen sein.
Die Schlitzbefestigung 4 ist unter einem Winkel Gamma,
z. B. 45°, zur Tangente der Mantelfläche 3 des Zylinders
1 geneigt. Die Winkel Alpha und Beta der
Einhängeabkantungen 8, 9 der Platte 2 sind dem Winkel
Gamma der Schlitzbefestigung 4 angepaßt.The
Dem Zylinder 1 ist eine Vorrichtung 13 für die
Einhängeabkantung 7 der Platte 2 am Ende 7
zugeordnet. Diese Vorrichtung 13 besteht im
wesentlichen aus einer mit einer Leitfläche 14
versehenen Traverse 16, einem Zuführschlitten 17 und
einem Einführschieber 18. Die Leitfläche 14 ist als
ebene Platte ausgebildet, deren erste Richtung sich
axial entlang der Länge des Zylinders 1 und deren zweite
Richtung sich radial bezüglich des Zylinders 1
erstreckt. Entlang dieser ebenen Leitfläche 14, d. h. in
radialer Richtung bezüglich des Zylinders 1 ist der
Zuführschlitten 17 bewegbar angeordnet. Der
Zuführschlitten 17 weist eine zweite, ebene Leitfläche
19 auf, deren erste Richtung sich ebenfalls axial
entlang der Länge des Zylinders 1 und deren zweite
Richtung parallel zur Lage der Schlitzbefestigung 4 des
in Einführstellung "E" positionierten Zylinders 1
verläuft. Entlang dieser Leitfläche 19 des
Zuführschlittens 17 ist der Einführschieber 18 bewegbar
angeordnet. Dieser Einführschieber 18 ist als
planparallele Platte ausgeführt, dessen dem Zylinder 1
zugewandte Stirnseite 21, beispielsweise unter 45°,
abgeschrägt ausgebildet ist, so daß die Stirnseite 21
annähernd senkrecht zur Leitfläche 14 des
Zylinderschlittens 17 steht. Der Einführschieber 18 ist
in Richtung Leitfläche 14 bewegbar bis die Stirnseite 21
des Einführschiebers 18 die Leitfläche 19 des
Zuführschlittens 17 erreicht.
Die Bewegungen von Zuführschlitten 17 und
Einführschieber 18 können beispielsweise mittels nicht
dargestellter Pneumatikzylinder ausgeführt werden.
Die gesamte Vorrichtung 13 kann aus einer
zylindernahen Arbeitsstellung (Fig. 2 - 5) in eine
zylinderferne Ruhestellung (Fig. 1) gebracht werden.
Hierzu können gestellfeste, nicht dargestellte
Linearführungen vorgesehen sein, auf denen die
Vorrichtung mittels Stellantriebe, z. B.
Pneumatikzylinder, bewegbar angeordnet ist.The
The movements of the
Weiterhin ist dem Zylinder 1 ein radial bewegbarer,
ansonsten gestellfester Rastbolzen 22 zugeordnet, um
eine exakte Einführstellung "E" des Zylinders 1 zu
gewährleisten. Der Rastbolzen 22 ist an seinem dem
Zylinder 1 zugewandten Ende 23 konisch ausgebildet.
Dieses konische Ende 23 wirkt mit einer ebenfalls
konischen, dem Ende des Rastbolzen angepaßten Aussparung
24 am Zylinder 1 zusammen. Der Rastbolzen 22 kann
beispielsweise an der Traverse 16 der Vorrichtung
13 befestigt sein. Durch die Bewegung der
Vorrichtung 13 von der Ruhestellung in die
Arbeitsstellung greift der Rastbolzen 22 in die
außerhalb der Plattenbreite befindlichen Aussparung 24
des Zylinders 1 ein und bestimmt somit die
Einführstellung "E" des Zylinders 1 exakt.Furthermore, the
Oberhalb der Vorrichtung 13 ist eine sich axial
entlang des Zylinders 1 erstreckende, drehbare
Andrückwalze 26 angeordnet. Diese Andrückwalze 26 ist an
die Mantelfläche 3 an- und abstellbar ausgeführt, wobei
die An- und Abstellbewegung, z. B. mittels
Pneumatikzylinder, erfolgt. Die Andrückwalze 26 kann mit
einer weichen Beschichtung, z. B. Gummi, versehen und
ein- oder mehrteilig ausgeführt sein. Anstelle der
Andrückwalze 26 können aber auch andere Andrück- bzw.
Halteelemente verwendet werden. Above the
Der Montagevorgang der Platte 2 verläuft folgendermaßen:
Der Zylinder 1 wird in eine Montagestellung positioniert
(Fig. 1). Hier hakt, z. B. ein Bediener oder eine
Vorrichtung die Einhängeabkantung 8 am Anfang 6 in
die Schlitzbefestigung ein und der Zylinder 1 beginnt in
Produktionsrichtung "P" zu drehen. Der Zylinder 1 wirkt
beispielsweise mit einem zweiten Zylinder 27, z. B.
einem Gummizylinder, zusammen, wobei der Zylinder 27 die
Platte 2 auf dem Zylinder 1 aufwalzt. Die Platte 2
kann aber auch von der Andrückwalze 26 auf dem
Zylinder 1 aufgewalzt werden. Der Zylinder 1
dreht bis die Einführstellung "E" erreicht ist und
stoppt. Dabei wird die Andrückwalze 26 angestellt und
preßt somit die Platte 2 auf dem Zylinder 1 an. Zur
exakten Positionierung des Zylinders 1 wird nun der
Rastbolzen 22 in die Aussparung 24 des Zylinders 1
gebracht und ist somit genau justiert. Dies kann wie im
vorliegenden Ausführungsbeispiel mit der Bewegung der
Vorrichtung 13 von ihrer Ruhe- in ihre
Arbeitsstellung erfolgen. Die beiden Bewegungen können
aber auch unabhängig voneinander ausgeführt werden.
Die Vorrichtung 13 steht nun mit ihrer Leitfläche
14 im Bereich der Schlitzbefestigung 4 unmittelbar und
radial vor der Mantelfläche 3 des Zylinders 1.The assembly process of
Ein nicht aufgewalztes Ende 7 der Platte 2 steht nun
infolge Eigenspannung der Platte 2 von einer Ablöselinie
25 zwischen Platte 2 und Andrückwalze 26 tangential ab,
wobei die Andrückwalze 26 derart angeordnet ist, daß die
Einhängeabkantung 9 am Ende 7 von der Vorrichtung 13
erfaßt werden kann.A
Auch ist es möglich die Andrückwalze 26 entfallen zu
lassen, wobei dann die Ablöselinie 25 vom zweiten
Zylinder 27 bestimmt wird.
Zum Erfassen der Einhängeabkantung 9 am Ende 7 der
Platte 2 von der Vorrichtung 13 kann die Vorrichtung 13
auch, z. B. mittels einer Schwenkbewegung von dem
Zylinder 1, auf das Ende 7 der Platte 2 zubewegt werden.
Nach dem Erfassen des Endes 7 der Platte 2 kann auch die
Vorrichtung 13 in einer weiteren, nicht dargestellten
Ausführungsvariante zusammen mit dem erfaßten Ende 7 der
Platte 2 in den Bereich der Schlitzbefestigung 4 bewegt
werden.
Der Zuführschlitten 17 wird nun in Richtung
Schlitzbefestigung 4 bewegt, wobei der Einhängeschenkel
12 der Einhängeabkantung 9 entlang der Leitfläche 14
geführt wird. Hierdurch wird der freie Teil der Platte 2
zwischen der Andrückwalze 26 und dem Zuführschlitten 17
bogenförmig vorgespannt, so daß dieser nur im Bereich
der Andrückwalze 26 und der Schlitzbefestigung 4 am
Zylinder 1 anliegt.
Somit wird ein Abstand von Ablöselinie 25 der
Andrückwalze 26 bis Ende des Einhängeschenkels 12 der
Einhängeabkantung 9 verkürzt. Die "verkürzende"
Verformung der Platte 2 erfolgt vorzugsweise elastisch.
Eine Sehnenlänge l1 zwischen Ablöselinie 25 und Ende des
Einhängeschenkels 12 der Platte 2 am Ende 7 wird einer
Sehnenlänge l2 zwischen Ablöselinie 25 und
Schlitzbefestigung 4 angepaßt. Der Einhängeschenkel 12
der Einhängeabkantung 9 steht im Bereich der
Schlitzbefestigung 4 auf Höhe der Mantelfläche 3 des
Zylinders 1.It is also possible to omit the
