- the left hanging lug 2 is molded directly into the plate cylinder 1, while the right hanging lug 3 is pivotally arranged, for example, on a clamping spindle 19. It is also possible to make both hook-in lugs 2, 3 pivotable. In a tensioned state, the tensioning spindle 19 continuously continues the contour 9 of the plate cylinder 1 with the hanging nose 3.

- a torque is now introduced into the clamping spindle 19 by means of the worm gear 29.
- the bearing surface 24 is pressed onto the support surface 26 and forms a new pivot axis 41.
- the clamping spindle 19 is now lifted off the molding compound 28 about this new pivot axis 41, moved outward in the direction of the contour 6 and pressed with its surface 22 against the support surface 23 of the plate cylinder 1. A clear, splinter-free position of the clamping spindle 19 and the hook-in nose 3 is thus achieved. This second pivoting movement takes place within a play between the clamping spindle 19 and the molding compound 28.
- the hook-in nose 3 can only be supported at its ends in the axial direction in two bearing rings.
- the inside diameter of the bearing rings is somewhat larger than the outside diameter of the clamping spindle 19 stored therein.
- a bearing is provided as a positive guide, which brings the bearing surface 24 of the hooking lug 3 into contact with the support surface 26 of the plate cylinder 1.
- Hanging nose 3 and plate cylinder 1 are with surfaces 22, 24; 23; 26 provided which form a positive guidance. Due to this positive guidance, the hook-in nose 3 is pressed without play out of the channel 11 in the direction of the contour 6 against the plate cylinder 1.

Ein Plattenzylinder 1 einer Rotationsdruckmaschine weist eine linke und rechte Einhängenase 2, 3 auf, die jeweils von Außen- und Innenfläche 4, 6, 7, 8 gebildet werden. Die jeweilige Außenfläche 4, 6 schließt mit der Innenfläche 7, 8 einen spitzwinkligen Öffnungswinkel Alpha von beispielsweise 45° ein und ist an eine Krümmung einer Kontur 9 des Plattenzylinders 1 angepaßt.A
Diese Einhängenasen 2, 3 verlaufen parallel zu einer Drehachse 5 des Plattenzylinders 1 und werden an ihrer Außenfläche 4, 6 von der Kontur 9 des Plattenzylinders 1 begrenzt. Unterhalb der beiden Einhängenasen 2, 3 verläuft ein Kanal 11 axial mit beispielsweise U-förmigen Querschnitt. In diesem Kanal 11 ist eine Dichtung 12, z. B. eine Rundschnur, eingelegt. Eine Druckplatte 13 oder eine Trägerplatte eines Gummituches ist mit ihren abgekanteten Enden 14, 16 in die Einhängenasen 2, 3 eingehängt. Abgekantete Schenkel 17, 18 dieser Enden schließen mit der Druckplatte ebenfalls einen Öffnungswinkel Alpha von beispielsweise 45° ein, der auf die Einhängenasen 2, 3 angepaßt ist. Die linke Einhängenase 2 ist direkt in den Plattenzylinder 1 eingeformt, während die rechte Einhängenase 3 schwenkbar beispielsweise an einer Spannspindel 19 angeordnet ist. Es ist auch möglich beide Einhängenasen 2, 3 schwenkbar auszuführen. In einem Spannendzustand setzt die Spannspindel 19 mit der Einhängenase 3 die Kontur 9 des Plattenzylinders 1 absatzlos, kontinuierlich fort.These hook-in
An die Außenfläche 6 der Einhängenase 3 schließt sich in Richtung Inneres 21 des Plattenzylinders 1 eine Fläche 22 an, die mit der Außenfläche 6 einen Öffnungswinkel Beta, z. B. Beta = 150°, einschließt. Eine auf diese Fläche 22 angepaßte Abstützfläche 23 ist an dem Plattenzylinder 1 in Richtung seines Inneren 21 angeformt. Dieser Fläche 22 annähernd gegenüberliegend ist an einer Unterseite einer Spitze der Einhängenase 3 eine Auflagefläche 24 angeordnet, für die ebenfalls eine an dem Inneren 21 des Plattenzylinders 1 direkt angeformte Abstützfläche 26 vorgesehen ist. Die beiden Abstützflächen 23, 26 verlaufen nicht parallel und schließen vorzugsweise einen Winkel Delta von 15° bis 30° ein, d. h. die beiden Abstützflächen 23, 26 sind nach außen verjüngend zueinander angeordnet. Die Spannspindel 19 ist in einer Zylindergrube 27 in einer gehärteten, schalenförmig ausgebildeten Formmasse 28 schwenkbar um ihre Drehachse 20 gelagert. Die Schwenkbewegung zum Spannen und Entspannen der Druckplatte 13 wird mittels eines an einem stirnseitigen Ende der Spannspindel 19 angeordneten Schneckengetriebes 29 erzeugt. Dieses selbsthemmende Schneckengetriebe 29 besteht im wesentlichen aus einem Zahnsegment 31, einer ersten Schnecke 32, einem Schneckenrad 33 und einer zweiten Schnecke 34. Die erste Schnecke 32 ist gemeinsam mit dem Schneckenrad 33 auf einer drehbar gelagerten Welle 36 befestigt. Diese Welle 36 ist rechtwinklig zur Spannspindel 19 an einer Stirnseite des Plattenzylinders 1 in zwei Lagerungen 37, 38 angeordnet. Die Schnecke 32 dieser Welle 36 greift in das stirnseitig befestigte Zahnsegment 31 der Spannspindel 19 ein, während das Schneckenrad 33 mit der zweiten Schnecke 34 kämmt. Die zweite Schnecke 34 ist im vorliegenden Ausführungsbeispiel mit einem Sechskant 39 zur Einleitung einer Drehbewegung versehen, aber es sind auch andere Stellantriebe, z. B. Schrittmotoren, möglich. Anstelle des Schneckengetriebes 29 sind auch andere Antriebe zur Erzeugung der Schwenkbewegung möglich.On the
Die Funktionsweise der erfindungsgemäßen Vorrichtung ist folgendermaßen:
Die Druckplatte 13 wird mit ihrem abgekanteten Ende 14 zuerst in die feststehende Einhängenase 2 am Druckanfang und z. B. nach einer Umdrehung mit ihrem Ende 16 in die geöffnete, d. h. nach außen geschwenkte Einhängenase 3 am Druckende eingehängt. Es ist aber auch möglich die feststehende Einhängenase 2 am Druckende und die schwenkbare Einhängenase 3 am Druckanfang anzuordnen und somit auch eine Drehrichtungsumkehr des Plattenzylinders 1 zu ermöglichen.The operation of the device according to the invention is as follows:
The
Mittel eines an dem Sechskant 39 angreifenden Werkzeuges wird nun an der zweiten Schnecke 34 gedreht, so daß diese Drehbewegung auf die Welle 36 und schließlich auf das Zahnsegment 31 übertragen wird. Dadurch schwenkt die Spannspindel 19 um ihre Drehachse 20 mit der Einhängenase 3 in Richtung Inneres 21 des Plattenzylinders 1 und spannt die Druckplatte 13. Nachdem der Spannendzustand nahezu erreicht ist, liegt die Auflagefläche 24 der Einhängenase 3 auf der Abstützfläche 26 auf. Über diese Stellung hinaus wird nun mittels des Schneckengetriebes 29 ein Drehmoment in die Spannspindel 19 eingeleitet. Dadurch wird die Auflagefläche 24 auf die Abstützfläche 26 gepreßt und bildet eine neue Schwenkachse 41. Um diese neue Schwenkachse 41 wird nun die Spannspindel 19 von der Formmasse 28 abgehoben, nach außen in Richtung Kontur 6 bewegt und mit ihrer Fläche 22 gegen die Abstützfläche 23 des Plattenzylinders 1 gedrückt. Somit ist eine eindeutige, splelfreie Position der Spannspindel 19 und der Einhängenase 3 erreicht. Diese zweite Schwenkbewegung erfolgt innerhalb eines Spiels zwischen Spannspindel 19 und Formmasse 28.A tool engaging the
Anstelle der Formmasse 28 kann auch eine andere Lagerung für die Einhängenase 3 angeordnet sein. So kann beispielsweise die Einhängenase 3 nur an ihren Enden in axialer Richtung in zwei Lagerringen gelagert sein. Der Innendurchmesser der Lagerringe ist dabei etwas größer als der Außendruchmesser der darin gelagerten Spannspindel 19.Instead of the
In jedem Fall ist eine Lagerung als Zwangsführung vorgesehen, die die Auflagefläche 24 der Einhängenase 3 in Kontakt mit der Abstützfläche 26 des Plattenzylinders 1 bringt.In any case, a bearing is provided as a positive guide, which brings the
Einhängenase 3 und Plattenzylinder 1 sind mit Flächen 22, 24; 23; 26 versehen, die eine Zwangsführung bilden. Durch diese Zwangsführung wird die Einhängenase 3 spielfrei aus dem Kanal 11 heraus in Richtung Kontur 6 gegen den Plattenzylinder 1 gedrückt.Hanging
