Description
Vorrichtung zum Aufbringen der geätzten Rohre auf die Formzylinder von Rotationstiefdruckmaschinen Bei Rotationstiefdruckmaschinen werden als Träger der Ätzungen häufig Kupferrohre oder verkupferte Rohre aus Aluminium, Eisen, Messing o. dgl. verwendet. Zum Aufbringen dieser Rohre auf die Formzylinderkerne werden diese entweder aus der Maschine genommen, oder das Aufbringen geschieht in der Maschine. Falls der Formzylinderkern für diese Arbeit in den Arbeitslagern verbleibt, wird im Seitengestell der Maschine eine Öffnung vorgesehen, durch die das Rohr über den Kern geschoben werden kann. Das Lager des Formzylinderkernes oder eine Zwischenhülse zwischen diesem und dem Seitenteil wird auf dieser Seite entfernt.Device for applying the etched tubes to the forme cylinder Rotogravure printing presses Rotogravure printing presses are used as carriers the etchings are often copper pipes or copper-plated pipes made of aluminum, iron, brass or the like. Used. To apply these tubes to the forme cylinder cores these are either taken out of the machine, or they are applied in the machine. If the forme cylinder core remains in the labor camps for this work, will An opening is provided in the side frame of the machine through which the pipe can be passed over the Core can be pushed. The bearing of the forme cylinder core or an intermediate sleeve between this and the side part is removed on this side.
Das Aufschieben des polierten und geätzten Kupferrohres durch die entstehende Öffnung erfordert immerhin eine gewisse Geschicklichkeit und Sorgfalt der Arbeiter. Verletzungen und mithin Unbrauchbarwerden der Bilder auf den Kupferrohren sind nicht immer zu vermeiden.The sliding of the polished and etched copper pipe through the The resulting opening requires a certain skill and care the worker. Injuries and consequently the pictures on the copper pipes becoming unusable are not always to be avoided.
Durch die Erfindung wird ein leichtes und sicheres Aufbringen der Rohre ohne Beschädigungen oder Klemmungen ermöglicht.The invention makes it easy and safe to apply the Pipes without damage or jamming possible.
In der Zeichnung ist die Erfindung beispielsweise veranschaulicht, und zwar stellen dar: Abb. i einen Längsschnitt durch eine Vorrichtung gemäß der Erfindung und Abb. 2 eine Stirnansicht nach Abb. i.In the drawing, the invention is illustrated, for example, namely show: Fig. i a longitudinal section through a device according to FIG Invention and Fig. 2 is an end view according to Fig. I.
Auf den Formzylinderkern d ist das geätzte Kupferrohr c aufzubringen. Der Formzylinderkern ist mit seinem Lagerzapfen in dem Lager e gelagert, das in dem Tragkörper t ruht, der in Führungens des Maschinenrahmens g in senkrechter Richtung verschiebbar ist. Um das Rohr c aufzubringen, wird der Lagertragkörper t in die in der Zeichnung dargestellte Stellung gesenkt, nachdem der Formzylinderkern d auf der entgegengesetzten Seite gegen Herunterfallen gesichert worden ist. Das Lager e selbst bleibt auf dem Lagerzapfen u des Formzylinderkernes d. Der Lagerzapfen u ist mit einer Bohrung v und dem Gewinde w versehen, in das ein Schraubenbolzen x eingeschraubt werden kann. Dieser trägt die Führungsvorrichtung gemäß der Erfindung, die aus einer Säule a besteht, an der in einigem Abstande voneinander zwei oder mehr Führungsscheiben b1, b2 angebracht sind. Diese haben einen solchen Durchmesser, daß das aufzubringende geätzte Rohr c eine genaue Führung in Richtung der Achse des Formzylinderkernes d erhält und ohne Klernmungen auf diesen aufgeschoben werden kann. Um das Aufschieben des Rohres c auf die Führungsscheiben b1, b2 zu erleichtern, sind diese zweckmäßig an ihren vorderen Kanten konisch oder ballig ausgebildet.The etched copper pipe c is to be applied to the forme cylinder core d. The forme cylinder core is mounted with its bearing journal in the bearing e, which rests in the support body t, which can be displaced in the vertical direction while guiding the machine frame g. In order to apply the tube c, the bearing support body t is lowered into the position shown in the drawing after the forme cylinder core d has been secured against falling on the opposite side. The bearing e itself remains on the bearing journal u of the forme cylinder core d. The bearing journal u is provided with a bore v and the thread w into which a screw bolt x can be screwed. This carries the guide device according to the invention, which consists of a column a on which two or more guide disks b1, b2 are attached at some distance from one another. These have such a diameter that the etched tube c to be applied is guided precisely in the direction of the axis of the forme cylinder core d and can be pushed onto it without jamming. In order to facilitate the sliding of the tube c onto the guide disks b1, b2, these are expediently designed conically or spherically at their front edges.
An Stelle der Führungsscheiben kann naturgemäß auch ein Führungszylinder oderFührungskreuze o. dgl. angebracht werden, die eine sichere Führung des aufzubringenden Rohres in Richtung der Formzylinderachse ermöglichen und zu diesem Zwecke gleich oder etwas kleiner im Durchmesser sein müssen als der Formzylinderkern d.Instead of the guide disks, a guide cylinder can naturally also be used or guide crosses o. the like. Are attached, the safe guidance of the to be applied Allow tube in the direction of the forme cylinder axis and for this purpose the same or must be slightly smaller in diameter than the forme cylinder core d.
Die Vorrichtung läßt' sich leicht an bereits vorhandene Maschinen anpassen. Es ist lediglich erforderlich, daB der Lagerzapfen u mit dem entsprechenden Befestigungsgewinde versehen wird. An Stelle des Gewindes w kann naturgemäß auch eine beliebige andere Befestigungsvorrichtung, beispielsweise ein Bajonettverschluß o. dgl., gewählt werden. Vielfach wird es auch genügen, die Führungsvorrichtung einfach in eine Bohrung des Lagerzapfens ohne eine besondere Befestigungsvorrichtung einzustecken.The device can 'easily be connected to existing machines adjust. It is only necessary that the bearing pin u with the corresponding Fastening thread is provided. Instead of the thread w can of course also any other fastening device, for example a bayonet lock or the like, can be selected. In many cases, the guide device will also suffice simply into a hole in the bearing journal without a special fastening device to plug in.
