Description

Die Erfindung betrifft eine Einrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a device according to the preamble of claim 1.

Eine solche Einrichtung ist zum Beispiel aus der US-A-2,651,900 bekannt. Zum Auswechseln einer Bandrolle ist hierbei die Handhabung durch Hinter- und Untergreifen sehr umständlich.Such a device is known for example from US-A-2,651,900. To replace a tape roll, the handling by reaching behind and under is very cumbersome.

Es ist daher Aufgabe der Erfindung, eine gattungsgleiche Einrichtung zu schaffen, die eine einfachere Handhabung ermöglicht.It is therefore an object of the invention to provide a generic device that enables easier handling.

Gelöst wird diese Aufgabe nach dem kennzeichnenden Teil des Anspruchs 1. Weitere Ausbildungen der Erfindung gehen aus den Unteransprüchen hervor.This object is achieved according to the characterizing part of claim 1. Further developments of the invention emerge from the subclaims.

Die Erfindung wird anhand eines Ausführungsbeispiels näher beschrieben.The invention is described in more detail using an exemplary embodiment.

Es zeigt:

Fig. 1
in einer Axialschnittdarstellung eine Einrichtung;
Fig. 2
in einer perspektivischen Darstellung einen Federring (Seegerring) mit Stiften zum Spannen des Rings;
Fig. 3
eine Draufsicht auf die Einrichtung nach der Fig. 1 ohne eine Bandrolle.
It shows:
Fig. 1
a device in an axial section;
Fig. 2
in a perspective view a spring ring (Seegerring) with pins for tensioning the ring;
Fig. 3
a plan view of the device of FIG. 1 without a tape roll.

In der Fig. 1 ist eine Einrichtung 1 zum lösbaren Aufnehmen eines Wickelkerns 2 einer Bandrolle 3 auf einem Dorn 4 mittels einer federbelasteten, manuell zu bedienenden Bandrollenwechseleinrichtung dargestellt, wobei der Dorn 4 auf einem feststehenden Lagerzapfen 5 axial drehbar angeordnet ist. Der Dorn 4 ist mit einer Nabe 6 versehen, die mit einer Scheibe 7 verbunden ist. Zwischen der Nabe 6 und einem Absatz 8 des Dorns 4 ist konzentrisch ein Federring 9 mit einem Axialspiel angeordnet. Im entlasteten Zustand weist der Federring 9 einen größeren Außendurchmesser auf als ein Innendurchmesser des Wickelkerns 2. Durch diese Maßnahme ist der Wickelkern 2 über den Federring 9 mit dem Dorn 4 koaxial drehbar verbunden, wobei der Dorn 4 einen kleineren Durchmesser 11 aufweist als der Innendurchmesser 10 des Wickelkerns 2. Zum Spannen des Federrings 9 zwecks Auswechselns einer Bandrolle 3 ist ein erstes freies Ende 12 des Federrings 9 beweglich mit dem Dorn 4 und ein zweites freies Ende 13 des Federrings 9 mit der Nabe 6 verbunden, wobei der Dorn 4 mit einer Freilaufeinrichtung 14 versehen ist und der Lagerzapfen 5 als eine Freilaufwelle vorgesehen ist. Als Federring 9 ist ein Seegerring 9A mit innerhalb des Außendurchmessers angeordneten Öffnungen 15, 16 vorgesehen, wobei eine Öffnung 15 über einen Stift 17 mit dem Dorn 4 und eine andere Öffnung 16 über einen anderen Stift 18 mit der Nabe 6 verbunden ist. Zwecks besserer Darstellung sind die beiden Stifte 17, 18 diametral gegenüberliegend dargestellt, wobei die richtige Lage aus der Fig. 2 entnehmbar ist, ebenso aus der Draufsicht auf die Einrichtung 1 nach der Fig. 3.1 shows a device 1 for releasably receiving a winding core 2 of a tape roll 3 on a mandrel 4 by means of a spring-loaded, manually operated tape roll changing device, the mandrel 4 being arranged axially rotatably on a fixed bearing journal 5. The mandrel 4 is provided with a hub 6 which is connected to a disk 7. A spring ring 9 with an axial play is arranged concentrically between the hub 6 and a shoulder 8 of the mandrel 4. In the relieved state, the spring ring 9 has a larger outer diameter than an inner diameter of the winding core 2. By this measure, the winding core 2 is rotatably connected to the mandrel 4 via the spring ring 9, the mandrel 4 having a smaller diameter 11 than the inner diameter 10 of the winding core 2. To tension the spring ring 9 for the purpose of replacing a tape roll 3, a first free end 12 of the spring ring 9 is movably connected to the mandrel 4 and a second free end 13 of the spring ring 9 is connected to the hub 6, the mandrel 4 being connected to a freewheel device 14 is provided and the journal 5 is provided as a freewheel shaft. A circlip 9A with openings 15, 16 arranged within the outer diameter is provided as the spring ring 9, one opening 15 being connected to the mandrel 4 via a pin 17 and another opening 16 being connected to the hub 6 via another pin 18. For a better illustration, the two pins 17, 18 are shown diametrically opposite one another, the correct position being evident from FIG. 2, likewise from the top view of the device 1 according to FIG. 3.

Zum Auswechseln einer Bandrolle 3 wird in Richtung eines Pfeils 19 (Fig. 3) die Scheibe 7 gedreht, wobei durch die Freilaufeinrichtung 14 der Dorn 4 am Drehen in dieser Richtung gehindert wird, was zur Folge hat, daß durch die sich in Pfeilrichtung 19 drehende Scheibe 7 die Nabe 6 und damit der Stift 18 derart mitgenommen wird, daß der Seegerring 9A zusammengedrückt wird und dadurch in etwa den Außendurchmesser 11 des Dorns 4 annimmt, wodurch ein Lösen des Wickelkerns 2 möglich ist. Durch diese Einrichtung 1 ist es nunmehr möglich, mit der einen Hand in Pfeilrichtung 19 die Wechseleinrichtung zu bedienen und andererseits mit der anderen Hand den Wickelkern 2 einer leeren Bandrolle 3 zu entnehmen und eine neue Bandrolle 3 mit einem Wickelkern 2 aufzusetzen, ohne daß ein Hinter- oder Untergreifen erforderlich ist. Anstatt am Randbereich der Scheibe 7 die Einrichtung 1 zu betätigen, können griffige Betätigungselemente 20 vorgesehen werden, die vorzugsweise radial am Randbereich der Scheibe 7 angeordnet sind. Die Bandrollenabwickeldrehrichtung ist wegen der Freilaufeinrichtung 14 entgegengesetzt der Pfeilrichtung 19.To replace a tape roll 3, the disc 7 is rotated in the direction of an arrow 19 (FIG. 3), the freewheel device 14 preventing the mandrel 4 from rotating in this direction, with the result that the one rotating in the direction of the arrow 19 Disc 7, the hub 6 and thus the pin 18 are taken along in such a way that the circlip 9A is pressed together and thereby assumes approximately the outer diameter 11 of the mandrel 4, whereby the winding core 2 can be released. Through this device 1 it is now possible to operate the changing device with one hand in the direction of the arrow 19 and, on the other hand, to take the winding core 2 from an empty tape roll 3 with the other hand and to put on a new tape roll 3 with a winding core 2, without having to reach behind or under it. Instead of actuating the device 1 at the edge region of the disc 7, non-slip actuation elements 20 can be provided, which are preferably arranged radially at the edge region of the disc 7. The direction of tape roll unwinding is opposite to the direction of arrow 19 because of the freewheel device 14.

Die beiden Stifte 17, 18 sind radial zur Längsachse des Lagerzapfens 5 angeordnet um eine Unwucht der aufgenommenen Bandrolle 3 zu verhindern.The two pins 17, 18 are arranged radially to the longitudinal axis of the bearing journal 5 in order to prevent the tape roll 3 from being imbalanced.

Die beiden Stifte 17, 18 können wahlweise fest mit dem Seegerring 9A und drehbar mit dem Dorn 4/Nabe 6 verbunden werden oder fest mit dem Dorn 4/Nabe 6 und drehbar mit dem Seegerring 9A.The two pins 17, 18 can either be fixedly connected to the circlip 9A and rotatably to the mandrel 4 / hub 6 or fixedly to the mandrel 4 / hub 6 and rotatably connected to the circlip 9A.

Zum Auswechseln der Einrichtung 1 gegen eine andere Größe ist eine Halteeinrichtung zum axialen Fixieren, zum Beispiel in Form eines Seegerrings 21, vorgesehen.To replace the device 1 with another size, a holding device for axial fixing, for example in the form of a circlip 21, is provided.
