PATENTAMT.PATENT OFFICE.
Der Gegenstand vorliegender Erfindung bezieht sich auf eine Vorrichtung zum Befestigen von Papphülsen auf einer kegelförmigen Spulmaschinenspindel. Es wird durch ihn in neuer Weise die zum Halten der Hülse dienende Klaue zwangläufig bewegt, so daß ihre erforderliche Lageveränderung sowohl beim Spannen wie beim Entspannen unbedingt. vor sich gehen muß undThe subject matter of the present invention relates to a device for fastening of cardboard tubes on a conical winding machine spindle. Through him it becomes in a new way that it is held the sleeve serving claw inevitably moves, so that their required change in position both when tightening and when relaxing. must go on and
ίο ein zeitweiliges Versagen derselben ausgeschlossen ist. ίο a temporary failure of the same is excluded.
Die Erfindung ist in beiliegender Zeichnung durch ein Ausführungsbeispiel veranschaulicht: The invention is illustrated in the accompanying drawing by means of an exemplary embodiment:
iS Die Spindel α trägt einen zweckmäßig aus Holz hergestellten Kegel b, welcher mittels eines auf das Ende des Spindelhalses aufgeschraubten Gewindestückes c gegen den tellerförmigen Bund a} der Spindel gepreßt und dadurch festgehalten wird. In Längsnuten des Spindelhalses α liegt die als zweischenklige Feder o. dgl. ausgebildete Spannklaue d, deren gezahnte Spannbacken e in Schlitz-Öffnungen des Kegels b geführt sind. Ein nach außen gehender Zapfen / der Spannklaue trägt ein auf ihm drehbar befestigtes Gewindestück g, dessen Gewinde mit demjenigen der feststehenden Büchse c in Eingriff steht. Je nach der Drehrichtung des Gewindestückes g wird die Spannklaue d in Richtung der Pfeile 1 oder 2 verschoben, wobei deren Spannbacken e in der Pfeilrichtung 3 bezw. 4 zu bewegen sind, um ein Festspannen bezw. Loslassen der Papphülse i zu bewirken. Diese Bewegungen werden dadurch zwangläufig herbeigeführt, daß die Klauen beim Spannen (Pfeilrichtung 1 und 3) auf der kegelförmigen Verstärkung der Spindel-Λ aufsteigen und infolgedessen auseinandergetrieben werden, beim Entspannen aber (Pfeilrichtung 2 und 4) die federnden Schenkel d an die Ecken b1 des Kegels b treffen, welche diese einwärts drängen, so daß die Backen e dann zum Loslassen der Papphülse gezwungen sind. In beschriebener Art erfolgt demnach immer eine zwangläufige Bewegung der Spannklaue, zufolge welcher sowohl ein sicheres Festhalten der zu bewickelnden Hülse, als auch ein sicheres Loslassen der Hülse nach vollendeter Bewickelung erreicht wird. iS The spindle α carries a cone b, suitably made of wood, which is pressed against the plate-shaped collar a} of the spindle by means of a threaded piece c screwed onto the end of the spindle neck and is thereby held in place. The clamping claw d, designed as a two-legged spring or the like, lies in longitudinal grooves of the spindle neck α , the toothed clamping jaws e of which are guided in slot openings in the cone b. An outwardly extending pin / the clamping claw carries a threaded piece g rotatably fastened on it, the thread of which engages with that of the fixed sleeve c . Depending on the direction of rotation of the threaded piece g , the clamping claw d is displaced in the direction of arrows 1 or 2, with their clamping jaws e in the direction of arrow 3 respectively. 4 are to be moved to bezw a clamping. Letting go of the cardboard sleeve i to effect. These movements are inevitably brought about by the fact that the claws rise up on the conical reinforcement of the spindle Λ when tensioning (arrow direction 1 and 3) and are consequently driven apart, but when relaxing (arrow direction 2 and 4) the resilient legs d to the corners b 1 of the cone b , which urge it inwards, so that the jaws e are then forced to let go of the cardboard tube. In the manner described, there is always an inevitable movement of the clamping claw, as a result of which both a secure holding of the sleeve to be wound and a reliable release of the sleeve after the winding has been completed is achieved.
Anstatt der Klaue mit federnden Schenkeln könnte man auch eine solche mit beispielsweise in Scharnieren drehbaren Schenkeln verwenden. Instead of the claw with resilient legs, one could also have one with, for example use hinged legs.
