Erfindungsgemäß wird die Aufgabe durch die Ausbildungsmerkmale des Hauptanspruches gelöst. Weiterbildungen ergeben sich aus den Unteransprüchen.According to the invention, the task is based on the training features of the main claim solved. Further training results itself from the subclaims.

Ein erster Vorteil der erfindungsgemäßen Anschlagvorrichtung ist darin begründet, das diese eine einfachen Aufbau hat und manuell oder in Verbindung mit einer Handhabevorrichtung, zum Beispiel einem Industrieroboter, zum Wechseln rotationssymmetrischer Bauteile, insbesondere von Zylindern und/oder Walzen, in einer Druckmaschine einsetzbar ist.A first advantage of the stop device according to the invention is because this is a simple one Has structure and manually or in connection with a handling device, for example an industrial robot, for Changing rotationally symmetrical components, in particular of cylinders and / or rollers, in a printing press can be used.

Von Vorteil ist weiterhin das zwischen dieser Anschlagvorrichtung und einem rotationssymmetrischen Bauteil, welches ausgewechselt werden soll, ein Formschluß erzeugbar ist, der bei Bedarf lösbar ist. Damit ist ein sicheres Anschlagmittel geschaffen, welches eine mögliche Unfall- und Verletzungsgefahr bei einem derartigen Bauteilwechsel spürbar reduziert.Another advantage is that between this stop device and a rotationally symmetrical component, which should be replaced, a positive connection can be generated is that can be solved if necessary. This is a safe one Created sling gear, which a possible accident and risk of injury when changing components noticeably reduced.

Vorteilhaft ist ebenso, das durch den erzielbaren Formschluß von Anschlagvorrichtung und rotationssymmetrischem Bauteil eine Lagesicherung des Bauteiles realisierbar ist und die Rüstzeiten beim Wechsel dieser Bauteile verkürzbar sind. So kann das rotationssymmetrische Bauteil in kurzer Zeit aus Lagerungen der Druckmaschine heraus bzw. von außerhalb in die Druckmaschine hinein transportiert und in Lagerungen eingesetzt werden. Alternativ ist ebenso ein Austausch von rotationssymmetrischen Bauteilen, vorzugsweise untereinander, in Lagerungen von Druckwerk zu Druckwerk bzw. Lackwerk und umgekehrt kurzfristig realisierbar.
Besonders vorteilhaft ist der Einsatz der vorzugsweise automatisiert betreibbaren Anschlagvorrichtung in Verbindung mit einer Handhabevorrichtung. Beispielsweise ist der Wechsel eines rotationssymmetrischen Bauteiles in Verbindung mit einer Handhabevorrichtung, zum Beispiel einem Industrieroboter, Manipulator oder einem Linearsystem, realisierbar, indem an der Handhabevorrichtung zwei synchron bewegliche Anschlagvorrichtungen angeordnet sind, um das rotationssymmetrische Bauteil jeweils endseitig mittels Formschluß sicher aufzunehmen. It is also advantageous that the positional locking of the component can be achieved by the attainable positive locking of the stop device and the rotationally symmetrical component and the set-up times can be shortened when changing these components. In this way, the rotationally symmetrical component can be transported out of the printing press bearings or into the printing press from outside and used in bearings in a short time. Alternatively, an exchange of rotationally symmetrical components, preferably among one another, in bearings from printing unit to printing unit or coating unit and vice versa can also be realized at short notice.
The use of the preferably automatically operated stop device in conjunction with a handling device is particularly advantageous. For example, the replacement of a rotationally symmetrical component in connection with a handling device, for example an industrial robot, manipulator or a linear system, can be implemented by arranging two synchronously movable stop devices on the handling device in order to securely hold the rotationally symmetrical component at the end by positive locking.

Das rotationssymmetrische Bauteil weist dabei an beiden Enden, im Bereich des Zylinderballens bzw. der Zylinderschulter bzw. des Zylinderzapfens entsprechende Öffnungen, bevorzugt Bohrungen, auf, um mit der Anschlagvorrichtung eine lösbar formschlüssige Verbindung zu realisieren.The rotationally symmetrical component faces both Ends, in the area of the cylinder barrel or the cylinder shoulder openings corresponding to the cylinder journal, prefers bores on to with the stop device to realize a detachable positive connection.

Bevorzugt ist das Kraftsystem 9 eine konzentrisch zum Bolzen 10 angeordneten Druckfeder, welche sich im Inneren der Kugeltraghülse 1 abstützt. An seinem oberen Ende ist der Bolzen 10 mit der Betätigungseinrichtung 4 in Funktionsverbindung. Der Betätigungseinrichtung 4 gegenüberliegend ist ein Oberteil 12 an der Kugeltraghülse 1 ortsfest angeordnet. Betätigungseinrichtung 4 und Oberteil 12 weisen bevorzugt Dichtungen 13 und 12 auf, welche den Innenraum der Kugeltraghülse 1 abdichten. Die Zuführleitung 8 mündet in dem von Betätigungseinrichtung 4 und Oberteil 12 gebildeten Bereich des Innenraumes der Kugeltraghülse 1 ein, so dass die zugeführte Energie, z.B. Druckluft, auf die Betätigungseinrichtung 4 wirkt. Dem Oberteil 12 ist ein Sensor 15 zugeordnet, welcher schaltungstechnisch mit einer zentralen Steuerung der Druckmaschine gekoppelt ist und zumindest die Position der Betätigungseinrichtung 4 (mit Bolzen 10) in einer Endlage erfaßt. Bevorzugt ist dabei die Endlage erfassbar, in der der Bolzen 10 die Kugeln 2 in der über den Umfang der Kugeltraghülse 1 hervorstehenden Position fixiert. Within the ball support sleeve 1, a bolt 10 is arranged to be linearly movable. In the upper area, the bolt 10 is functionally connected to the preferably pneumatically activatable actuating device 4.

When the bolt 10 moves the balls 2 over the tapered free rotation 11 lifted on the cylindrical bolt 10 and pushed outwards. The balls 2 are between bolts 10 and the openings arranged in the ball support sleeve 1 self-locking.

Bei Einsatz einer Handhabevorrichtung sind an dieser zwei Anschlagvorichtungen angeordnet, deren Betätigungseinrichtungen synchron aktivierbar sind. Die Anschlagvorrichtungen sind derart angeordnet, dass das auszuwechselnde Bauteil endseitig mit seinen Öffnungen sicher mit der Anschlagvorrichtung lösbar verbindbar ist. Dazu greift bei jeder Anschlagvorrichtung die Kugeltraghülse 1 formschlüssig in die Öffnungen des rotationssymmetrischen Bauteils ein und transportiert das Bauteil in eine freie Lagerung innerhalb eines Druckwerkes oder Lackwerkes und legt es dort ab.When using a handling device there are two Stop devices arranged, their actuators can be activated synchronously. The stop devices are arranged so that the to be replaced Component with its openings securely at the end the stop device is releasably connectable. To grips the ball bearing sleeve 1 for each stop device positively into the openings of the rotationally symmetrical Component and transports the component into a free storage within a printing unit or coating unit and put it there.

Alternativ ist ein rotationssymmetrisches Bauteil endseitig auch manuell mit je einer Anschlagvorrichtung über je eine Kugeltraghülse 1 lösbar verbindbar und ist von einem bzw. mehreren Bediener/Bedienern z.B. zu einer Ablage transportierbar und dort ablegbar. Hierzu umgreift der Bediener den Griff 6 und aktiviert die Betätigungseinrichtung 4. Nach Herstellung des Formschlusses zwischen Kugeltraghülse 1 und der entsprechenden Öffnung im rotationssymmetrischen Bauteil ist das Bauteil aus der Lagerung entnehmbar. Der Griff 6 ist hierbei im Drehgelenk 3 umlegbar, so dass unter Ausnutzung der Abdrückkurve 7 das rotationssymmetrische Bauteil leichter aus der Lagerung entnehmbar ist.
Nach der Ablage des rotationssymmetrischen Bauteiles kann ein weiteres rotationssymmetrisches Bauteil mittels Anschlagvorrichtung formschlüssig aufgenommen werden.
Zur verbesserten Einführung der Kugeltraghülse 1 in eine zugeordnete Öffnung eines rotationssymmetrischen Bauteiles weist diese endseitig eine kegelig oder gekrümmte Einführhilfe 16 auf. Alternatively, a rotationally symmetrical component can also be detachably connected at the end manually with one stop device each via a ball support sleeve 1 and can be transported to a storage area by one or more operators, for example, and stored there. For this purpose, the operator grips the handle 6 and activates the actuating device 4. After the positive connection between the ball bearing sleeve 1 and the corresponding opening in the rotationally symmetrical component, the component can be removed from the storage. The handle 6 can be folded over in the swivel joint 3, so that the rotationally symmetrical component can be more easily removed from the storage by using the push-off curve 7.
After the rotationally symmetrical component has been deposited, a further rotationally symmetrical component can be positively received by means of a stop device.
To improve the insertion of the ball support sleeve 1 into an associated opening of a rotationally symmetrical component, the latter has a conical or curved insertion aid 16 at the end.
