Abstract

The free limbs of the levers partly encompass the axle boxes of the plate cylinder, to swing about a bolt near the transition between the rear free limb and the web connecting the two limbs. A knee lever hinge-linked to the other transition point, has its other end against a fixed stop on the side wall, engaged by a pneumatically or hydraulically operated piston acting on the centre of the knee lever. The knee-lever is designed to be self-locking.

Vorrichtung zum Auswechseln der Formzylinder von Rotationstief druckmas chinenDevice for changing the forme cylinder of rotogravure printing machines

Die Erfindung betrifft eine Vorrichtung zum Auswechseln der Formzylinder von Rotationstiefdruckmaschinen.The invention relates to a device for exchanging the forme cylinder of rotogravure printing machines.

Bekanntlich sind die Lagerbuchsen der Formzylinder in sich in Längsrichtung der Seitenwände erstreckenden Schlitzen gelagert und werden zum Auswechseln mit dem Formzylinder auf an diese anschließenden Trägern in Maschinenlängsrichtung entfernt. Da die Lagerbuchsen der Formzylinder in der Betriebs stellung verriegelt sind, kleben sie meist in den Seitenwänden infolge von Fetthaftung oder Farbhaftung fest und sind daher nur mit Hilfswerkzeugen und unter Aufwand von erheblicher Zeit und Kraft entfernbar.It is known that the bearing bushes of the forme cylinders are in themselves in the longitudinal direction the side walls extending slots and are for replacement with the forme cylinder on this adjoining Beams removed in the longitudinal direction of the machine. Since the bushings of the forme cylinders are locked in the operating position, they stick mostly stuck in the side walls as a result of grease adhesion or paint adhesion and are therefore only possible with auxiliary tools and at the expense of Removable after considerable time and effort.

Es ist Aufgabe der Erfindung, die Lagerung der Formzylinderenden derart auszubilden, daß der Ausbau des Formzylinders leicht und ohne Verwendung von besonderen Werkzeugen möglich ist.It is the object of the invention to design the storage of the forme cylinder ends in such a way that the removal of the forme cylinder is easy and is possible without the use of special tools.

Nach der Erfindung wird dies dadurch erreicht, daß in beiden Maschinenseitenwänden im Bereich der Lagerschlitze für die Buchsen desAccording to the invention, this is achieved in that in both machine side walls in the area of the bearing slots for the sockets of the

Formzylinders U-förmige Hebel schwenkbar gelagert sind, deren freie Schenkel die Lagerbuchsen teilweise umfassen. Durch diese Maßnahme wird mit Hilfe eines einzigen Hebelpaares sowohl eine Arretierung als auch das Entfernen des Formzylinders ermöglicht.Form cylinder U-shaped levers are pivotably mounted, the free legs of which partially encompass the bearing bushes. Through this Measure, both locking and removal of the forme cylinder is made possible with the aid of a single pair of levers.

Nach einer bevorzugten Ausführungsform sind die Hebel dabei um einen etwa am Übergang des hinteren freien Schenkels zum die Schenkel verbindenden Steg angebrachten Bolzen schwenkbar, wodurch ein günstiges Hebelverhältnis zum Entfernen des "Zylinders geschaffen wird.According to a preferred embodiment, the levers are around an approximately at the transition from the rear free leg to the leg connecting web attached bolt pivotable, creating a favorable lever ratio for removing the "cylinder created will.

Durch die gelenkige Befestigung eines Kniehebels am anderen Übergang des Hebels, dessen anderes Ende gegen einen festen Anschlag der Seitenwand mittels eines in der Kniehebelmitte einwirkenden pneu« matisch oder hydraulisch betätigten Kolbens anstellbar ist, wird das Einspannen zudem wesentlich vereinfacht und damit die Einspannzeit verkürzt.Through the articulated attachment of a toggle lever to the other transition of the lever, the other end of which is against a firm stop on the side wall by means of a pneumatic lever acting in the middle of the toggle lever automatically or hydraulically operated piston is adjustable, the clamping is also significantly simplified and thus the clamping time shortened.

Die Lagerbuchsen 1 der nicht näher angedeuteten Formzylinder sind in bekannter Weise in Längs schlitzen 2 der beiden Maschinenseitenwände 3 verschiebbar gelagert und mittels tl-förmiger Bügel 4 gehalten. Die Bügel 4 sind dabei um Zapfen 5 schwenkbar, die am Übergang vom einen freien Schenkel 6 des Hebels zum Steg angeordnet sind. Wie aus den Figuren hervorgeht, umfassen die beiden Schenkel 6 und 7 der Bügel 4 die Lagerbuchse 1 der Formzylinder auf der Unterseite teilweise und bestimmen somit ihre eindeutige Lage in den Seitenwänden. Zu diesem Zweck ist am Schenkel 7 des Bügels 4 ein Kniehebelpaar 8 gelenkig befestigt, dessen freies Ende gegen einen festen Anschlag 9 an der Seitenwand bewegbar ist, und zwar durch einen etwa in der Mitte des Kniehebelpaares 8 angreifenden pneumatisch oder hydraulisch betätigten Kolben 10.The bearing bushes 1 of the forme cylinders (not shown in more detail) are in a known manner in the longitudinal slots 2 of the two machine side walls 3 slidably mounted and held by means of tl-shaped bracket 4. The brackets 4 are pivotable about pins 5, which are arranged at the transition from a free leg 6 of the lever to the web. As can be seen from the figures, the two legs comprise 6 and 7 the bracket 4 partially the bearing bush 1 of the forme cylinder on the underside and thus determine their unique position in the side walls. For this purpose, a pair of toggle levers 8 is articulated on the leg 7 of the bracket 4, the free end of which is against a fixed one Stop 9 is movable on the side wall, namely by a pneumatic or hydraulic attacking approximately in the middle of the toggle lever pair 8 actuated piston 10.

In der Betriebs stellung ist der Kolben 10 in seiner äußersten Stellung, so daß der Formzylinder durch den Schenkel 7 verriegelt ist, wie Figur 1 zeigt. Das äußere Ende des Kniehebelpaares liegt gegen den Anschlag an und das Kniehebelpaar 8 selbst ist dann in Übertotpunktlage, bo daß die Bügel 4 praktisch verriegelt sind. Der Schenkel 6 ist in dieser Lage geringfügig von der Lagerbuchse 1 abgehoben.In the operating position, the piston 10 is in its extreme position, so that the forme cylinder is locked by the leg 7, as FIG. 1 shows. The outer end of the pair of toggle levers lies against the stop on and the toggle pair 8 itself is then in over-center position, bo that the bracket 4 are practically locked. The leg 6 is in this Position slightly lifted from the bearing bush 1.

Soll nun der Formzylinder ausgefahren werden, so werden die Kolben 10 durch Druckknopfbetätigung in die innere Stellung gefahren (Figur 2). Das Kniehebelpaar 8 rastet aus und die Bügel 4 schwenken um die Zapfen 5. Dabei hebt der Schenkel 7 von der Lagerbuchse 1 ab, während sich der Schenkel 6 gegen dieselbe anlegt und mit fortschreitender Abwärtsbewegung des Kolbens 10 eine Kraft auf die Lagerbuchsen ausübt, welche diese entgegen der Bearbeitungsrichtung aus den Längsschlitzen 2 bewegt und damit das Auswechseln ermöglicht.If the forme cylinder is now to be extended, the pistons will 10 moved into the inner position by pressing the button (Figure 2). The toggle pair 8 disengages and the bracket 4 pivot around the Pin 5. The leg 7 lifts from the bearing bush 1, while the leg 6 rests against the same and as it progresses Downward movement of the piston 10 exerts a force on the bearing bushes, which force them out of the longitudinal slots counter to the machining direction 2 moves and thus enables replacement.
