Description
Vorrichtung zum An- und Abstellen eines Druckwerkszylinders, insbesondere des Druckzylinders einer Rotationstiefdruckmaschine Die Erfindung betrifft eine Vorrichtung zum An-und Abstellen eines Druckwerkszylinders, insbesondere des Druckzylinders einer Rotationstiefdruckmaschine gegenüber der Zwischenwalze, mittels die beiden Enden des Zylindermantels stützender, durch Druckluftbetätigung verdrehbarer Exzenter.Device for switching a printing unit cylinder on and off, in particular of the printing cylinder of a rotogravure printing machine The invention relates to a Device for switching a printing unit cylinder on and off, in particular the printing cylinder a rotogravure printing machine opposite the intermediate roller, by means of the two Eccentric supports the ends of the cylinder jacket and can be rotated by compressed air.
Es ist bekannt, die Druckzylinder beidseitig in Exzenterbüchsen zu lagern und durch Verdrehen derselben, beispielsweise mittels von Druckluft betätigter Hebel, den Abstand zu benachbarten Walzen einzustellen. Eine derartige Verstellung zu beiden Seiten ist jedoch nur für das Drucken über die ganze Breite, hingegen nicht für das Bedrucken einer halbbreiten Bahn geeignet, weil dabei die Gefahr der Kantenpressung u. a. infolge einer geringen Durchbiegung des Druckzylinders besteht.It is known to close the pressure cylinder in eccentric sleeves on both sides store and actuated by rotating the same, for example by means of compressed air Lever to adjust the distance to adjacent rollers. Such an adjustment however, on both sides is only for printing across the entire width, however not suitable for printing on a half-width web because there is a risk of Edge pressure, etc. as a result of a slight deflection of the printing cylinder.
Ferner ist es bekannt, die beiden Enden eines Druckwerkszylinders gemeinsam oder ein Zylinderende für sich einzustellen. Mit diesen bekannten Vorrichtungen ist es jedoch nicht möglich, jedes Zylinderende für sich unabhängig vom anderen zu verstellen.It is also known that the two ends of a printing unit cylinder together or set one end of the cylinder separately. With these known devices However, it is not possible for each cylinder end to be independent of the other to adjust.
Um diesen Mangel zu beheben und einen gleichmäßigen Druck auch über eine halbbreite Papierbahn zu gewährleisten, sind erfindungsgemäß bei einer Vorrichtung der eingangs erwähnten Art die beiden Exzenter von der Bedienungsseite der Maschine aus einzeln oder mittels einer Verriegelung gemeinsam verdrehbar.To remedy this deficiency and apply an even pressure as well To ensure a half-width paper web are according to the invention in a device of the type mentioned above, the two eccentrics from the operator side of the machine can be rotated individually or together by means of a lock.
Durch diese Maßnahme in Verbindung mit der Anordnung der beiden mit Druckluft gesteuerten Betätigungseinrichtungen auf der einen Maschinenseite wird eine Deformation des Druckzylinders über seine Länge bzw. ein Kippen desselben verhindert und die genau parallele Einstellung auch bei halber Druckbreite zur anliegenden Walze ermöglicht.By this measure in conjunction with the arrangement of the two with Compressed air controlled actuators on one side of the machine prevents deformation of the printing cylinder over its length or tilting of the same and the exactly parallel setting even at half the print width to the adjacent one Roller enables.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Längsschnitt und in Stirnansicht gezeigt.In the drawing, an embodiment of the invention is in longitudinal section and shown in front view.
Der Druckzylinder 1 ist in der einen Seitenwand 2 (Bedienungsseite) auf einer Exzenterbuchse 3 mit Rollenlagem 4 gelagert. Die Umfangsverstellung der Exzenterbuchse 3 geschieht durch einen durch Druckluft betätigten Kolben 5, welcher auf einen Hebel 6 an der Buchse 3 einwirkt. Achsparallel innerhalb der Buchse 3 ist der Zapfen 7 einer Exzenterwelle 8 angeordnet, deren anderes Ende in einem Kugellager 9 in der Seitenwand 10 gelagert ist. Auf der Exzenterwelle 8 ist am der Seitenwand 10 zugekehrten Ende ein Rollenlager 11 für die Lagerung des Mantels des Druckzylinders 1 vorgesehen. Der Zapfen 7 ist mit einem Hebel 12 versehen, der ebenfalls mit einem von Druckluft steuerbaren Kolben 13 verbunden ist. Beim Bedrucken einer ganzen Bahn werden die Kolben 5 und 13 einzeln betätigt und demnach auch die Exzenter 3 und 8 einzeln verstellt. Soll hingegen nur eine halbbreite Bahn bedruckt werden, so werden die beiden Hebel 6 und 12 durch einen achsparallelen Bolzen 14 miteinander verriegelt. Werden nun die beiden Kolben 5 und 13 mit Druckluft beaufschlagt, so erfolgt ein gemeinsames Verdrehen der Exzenter bis zum Anliegen in der zu bedruckenden Hälfte. Ein Kippen des Druckzylinders durch ohne die Verriegelung zwangläufiges Weiterdrehen des Exzenters unter dem Luftdruck auf der nicht zu bedruckenden Hälfte wird damit verhindert. Nach Lösen des Bolzens 14 kann die Vorrichtung wieder für den Druck auf der vollen Breite benutzt werden.The printing cylinder 1 is mounted in one side wall 2 (operating side) on an eccentric bushing 3 with roller bearings 4. The circumferential displacement of the eccentric bush 3 is done by a switch actuated by compressed air piston 5, which acts on a lever 6 on the socket. 3 The pin 7 of an eccentric shaft 8 is arranged axially parallel within the bush 3 , the other end of which is supported in a ball bearing 9 in the side wall 10 . On the eccentric shaft 8 , at the end facing the side wall 10 , a roller bearing 11 is provided for mounting the jacket of the printing cylinder 1 . The pin 7 is provided with a lever 12 which is also connected to a piston 13 controllable by compressed air. When printing an entire web, the pistons 5 and 13 are actuated individually and, accordingly, the eccentrics 3 and 8 are also adjusted individually. If, on the other hand, only a half-width web is to be printed, the two levers 6 and 12 are locked to one another by an axially parallel bolt 14. If the two pistons 5 and 13 are now pressurized with compressed air, the eccentrics are rotated together until they are in contact with the half to be printed. A tilting of the printing cylinder by inevitably continuing to rotate the eccentric without the locking mechanism under the air pressure on the half that is not to be printed is thus prevented. After loosening the bolt 14, the device can be used again for printing over the full width.
Die erfindungsgemäße Anordnung der Exzenterbuchsen und der Verstellvorrichtungen ermöglicht gleichzeitig die Anbringung eines gemeinsamen Wicklerschalters, der die Maschine bei Stoppern selbsttätig abstellt und einer Einrichtung zum selbsttätigen Richtigstellen der Zwischenwalze und des Druckzylinders zum jeweils verwendeten Formzylinder.The inventive arrangement of the eccentric bushings and the adjustment devices at the same time enables the attachment of a common winder switch that controls the Machine stops automatically in the event of stoppers and a device for automatic Correcting the intermediate roller and the printing cylinder for each used Forme cylinder.
