Description

Ätz- und Wascheinrichtung für Tiefdruckwalzen. Das aufeinanderfolgende Entwickeln, Ätzen und Waschen der Kupferzylinder für Tiefdruck erfolgt in Trögen, in denen sich die der jeweiligen Arbeitsverrichtung angepaßte Flüssigkeit befindet. Bei dem hohen Eigengewicht der Tiefdruckzylinder ist das Überheben von einem Trog zum anderen selbst dann mit Mühe verbunden, wenn geeignete Hebezeuge zur Verfügung stehen..Etching and washing equipment for gravure rollers. The consecutive Developing, etching and washing of the copper cylinders for gravure printing takes place in troughs, in which the liquid adapted to the respective work is located. With the heavy weight of the gravure cylinders, they are lifted from a trough on the other hand, it is difficult even when suitable lifting equipment is available stand..

Zur Erleichterung und Beschleunigung der Entwicklungs-, Ätz- und Wascharbeit wird der Tiefdruckzylinder gemäß der Erfindung von einem mit Hebevorrichtung versehenen Wagen aufgenommen, der über den nebeneinander oder auch hintereinander ortsfest gelagerten Trögen derart angeordnet ist, daß der Druckzylinder unmittelbar nach Verrichtung der einen Arbeit über den nächstfolgenden Trog gefahren werden kann.To facilitate and accelerate the development, etching and washing work the gravure cylinder according to the invention is provided with a lifting device Car added, which is stationary over the side by side or one behind the other stored troughs is arranged so that the printing cylinder immediately after Performing one work can be driven over the next trough.

Auf der Zeichnung ist die Erfindung in einer beispielsweisen Ausführungsform dargestellt.In the drawing, the invention is in an exemplary embodiment shown.

Es zeigen die Abb. i die Wascheinrichtung im Längsschnitt, Abb.2 einen Querschnitt der Vorrichtung bei gesenktem Zylinder und Abb.3 einen Querschnitt bei gehobenem Zylinder.Fig. I shows the washing device in longitudinal section, Fig.2 shows a Cross-section of the device with the cylinder lowered and Fig. 3 a cross-section at raised cylinder.

Von einem angepaßten Gestell werden die Tröge a, d, a" beispielsweise in Längsrichtung hintereinander gehalten, die beiderseitig von Schienenbahnen b eingeschlossen werden, über denen ein Wagen g fahrbar gehalten wird.The troughs a, d, a "are for example of an adapted frame held one behind the other in the longitudinal direction, both sides of the railways b are included, over which a carriage g is kept mobile.

Der Wagen trägt an beiden Enden für die Aufnahme der Druckzylinderachsen Lagerstellen, die beispielsweise mit Armen h einer Längswelle i verbunden sein können, so daß durch angemessenes Drehen dieser Welle i die Arme la aufwärts oder abwärts geschwungen werden können und so das Ausheben des Druckzylinders k aus dem Trog (Abb. 3) Ader sein Eintauchen in diesen stattfindet (Abb. 2). Die -Verschwenkbarkeit der Arme h kann mittels eines einfachen Handhebels erfolgen, der in seinen beiden Endstellungen festlegbar ist, aber mit Rücksicht auf das hohe Gewicht der Druckzylinder erscheint es vorteilhafter, zum Verschwenken der Arme h eine Schraubenspindel m zu benutzen, mit deren Mutter x ein auf der Welle i befestigter Hebel p in Verbindung steht.The carriage carries bearing points at both ends to accommodate the printing cylinder axes, which can be connected, for example, to arms h of a longitudinal shaft i, so that by rotating this shaft i appropriately, the arms la can be swung up or down, thus lifting the printing cylinder k the trough (Fig. 3) vein is immersed in this takes place (Fig. 2). The pivoting of the arms h can be done by means of a simple hand lever, which can be fixed in its two end positions, but considering the heavy weight of the pressure cylinder, it seems more advantageous to use a screw spindle m with its nut x a to pivot the arms h on the shaft i mounted lever p is connected.

Selbstverständlich- läßt sich die Vorrichtung auch dann in der gleichen Weise verwenden, wenn die Tröge a nebeneinander gelagert werden, nur scheint diese Ausführungsform weniger vorteilhaft, weil die Arbeiten über dem mittleren Trog wegen seiner erschwerten Zugängigkeit in unbequemer Haltung ausgeführt werden müssen.Of course, the device can then also be used in the same way Use wise when the troughs are stored a side by side, this only appears Embodiment less advantageous because the work is due to the middle trough have to be carried out in an uncomfortable position due to its difficult accessibility.

In beiden Fällen kann die Fahrbahn b für den Wagen g so weit über das Traggestell hinaus, verlängert werden, daß sich die fertig bearbeiteten Zylinder durch den Wagen g über ein Fahrgestell bringen lassen, mit dessen Hilfe sie nach der Druckerpresse zu befördern sind.In both cases, the lane b for the car g can be so far over the support frame can be extended so that the finished cylinder can be brought by the carriage g over a chassis, with the help of which they after the printing press.
