Description

Es' ist-bei Registriereinrichtungen bekannt, 'ein' Papierband über Walzen laufen zu lassen, bei denen diese Walzen in irgendeiner Form, z. B. durch einen Motor, angetrieben. werden. Bei diesen Einrichtungen muß der Papierbogen gespannt sein, ein Zerreißen aber verhindert werden, anderseits muß eine möglichst leichte Auswechselung des Papierbandes ermöglicht werden. Beiden bekannten Einrichtungen dieser Art hat man -das Ende des Papierbandes in einen Schlitz der Walze einsgespannt. Schwierig ist nachher bei Herausnahme der Walze aus der Vorrichtung das Hinausziehen dier Wälze aus,der Papierrolle. Besonders wenn man, um das Papierband an der Walze festzuhalten, beim Einspannen .das Ende des Papierbandes gegen spitze Vorsprünge in der Walze bzw. im Schlitz der Walze preßt.It is known from registration devices to have a 'tape' of paper over it To run rollers, in which these rollers in some form, z. B. by a motor driven. will. With these facilities, the sheet of paper must be stretched but tearing must be prevented, on the other hand it must be as light as possible Exchange of the paper tape are made possible. Both known bodies In this way, the end of the paper tape was clamped into a slot in the roller. It is difficult to pull it out afterwards when the roller is removed from the device the roll out, the roll of paper. Especially when you get to the paper tape on the roller to hold on when clamping .the end of the paper tape against pointed protrusions presses in the roller or in the slot of the roller.

Gemäß der Erfindung wird nun ,die Anordnung so getroffen, daß an der Walze, auf welche das Papierband aufgerollt wird, verstellbare Nocken vorgesehen sind, derart"daß, sobald die Walze aus der Papierrolle herausgezogen werden soll, erst die Nocken, die das Ende des Papierbandes festklem= men, außer .Eingriff gebracht werden. Gleichzeitig -kann man durch Verstellender Nocken denen, Querschnitt der Walze verändern, so daß sie sich leichter aus der Papierrolle herausziehen: läßt.According to the invention, the arrangement is made so that on the Roller on which the paper tape is rolled up, adjustable cams are provided are such "that as soon as the roller is to be pulled out of the paper roll, only the cams that clamp the end of the paper tape, except .Eingriff brought will. At the same time, you can adjust the cams, the cross-section of the Change the roller so that it can be pulled out of the paper roll more easily.

Der Erfindungsgegenstand ist in den Figuren beispielsweise erläutert.The subject matter of the invention is explained in the figures, for example.

In Fig. i und 2 ist i eine Hülse, die zweckmäZi@gerweise einen Schlitz 2 aufweist, dessen Größe beim Hineinschieben einer Walze 3 vergrößert werden kann. Im Inneren der Hülse sind federnde Spitzen 4 angebracht, die durch öffnun gen der Hülse i hindurchragen können. Wird die Walze 3i in die Hülse i eingeschoben, so wird nicht nur der Schlitz 2 vergrößert, sondern es werden auch die Spitzen 4 nach außen .gedrängt. Rollt man nun das Ende des Papierbandes auf die Hülse i auf, so drücken sich die Spitzen 4 in das Papierbands ein und, halten-dieses. fest. Nach Aufspulen des Papierbandes auf die Hülsen, soll nun :die Hülse herausgezogen werden; dies :geschieht dadurch, saß .die Walze 3 aus .der Hülse herausgezogen wird. Die federnden Spitzen 4 treten zurück, so saß sie völlig in der Hülse verschwinden. Der Schlitz 2 und damit der Durchmesser der Hülse i verringert sich, und -die Hülse i kann nunmehr aus der Papierrolle herausgezogen werden.In Fig. I and 2, i is a sleeve, which expediently has a slot 2, the size of which can be increased when a roller 3 is pushed in. Inside the sleeve resilient tips 4 are attached, the gene by the opening Sleeve i can protrude. If the roller 3i is pushed into the sleeve i, so not only is the slot 2 enlarged, but the tips 4 also become larger outside. If you now roll the end of the paper tape onto the sleeve i, so the tips 4 press themselves into the paper tape and hold it. fixed. To When winding the paper tape onto the tubes, you should now: pull out the tube; this: happens because the roller 3 sat .the sleeve is pulled out. the resilient tips 4 step back, so they sat completely disappear in the sleeve. The slot 2 and thus the diameter of the sleeve i is reduced, and the sleeve i can now be pulled out of the paper roll.

Die Fig. 3 bis 5 zeigen ein anderes Ausführungsbeispiel. Hierbei ist eine Walze vorgesehen, die aus zwei Teilen 5 und, @6) besteht. Die beiden Teile sind bei 7 gelenkig miteinander verbunden. In dem Teil 5 der Walze ist eine Welle 8 vorgesehen, auf welcher sieh ,ein Nockenhebel9, befindet. Durch Drehender Welle 81 mittels -des Hebels 12 kann man .den Nocken 9 in den Schlitz io eintreten lassen oder aus diesem herausziehen. Wird das Ende i i .des Papierbandes in den Schlitz io eingelegt, wobeider Nocken 9 die Lage einnimmt, wie in Fig. 3 angedeutet, so ist .das Papierband unverschiebbar befestigt. Zweckmäßig werden: mehrere Nocken 9 vorgesehen, wie die Fig.4 zeigt. Ist nun das Papierband auf die Walze aufgespult, so werden durch.Drehen der Welle 8 die Nocken g aus. dem Schlitz io bewegt, und .das Papierband wird frei-.gegeben. Wählt man den Schlitz io, entsprechend groß, so kann durch Gegeneinamderbewegen der beiden Teile 5 und 6, wie aus Fig. 5 ersichtlich, der Querschnitt der Walze verringert werden, so @daß das Herausziehen .der Walze noch erleichtert wird. Zweckmäßig sieht man jedoch. Anschlagflächen 13 vor, gegen die das Teil 6 der Walze stößt und die so bemessen sind,'daß bei Verringerung .des Durchmessers- der Walze dennoch der Schlitz io in solcher Breite bestehenbleibt, daß das Ende des Papierbandes herausgezogen werden kann.FIGS. 3 to 5 show another embodiment. Here, a roller is provided which consists of two parts 5 and @ 6). The two parts are articulated to one another at 7. In the part 5 of the roller a shaft 8 is provided on which you see a cam lever 9 is located. By rotating the shaft 81 by means of the lever 12, one can let the cam 9 enter the slot or pull it out of it. If the end ii. Of the paper tape is inserted into the slot io, with the cam 9 assuming the position as indicated in Fig. 3, then the paper tape is fixed in such a way that it cannot be displaced. The following are expedient: several cams 9 are provided, as FIG. 4 shows. If the paper tape is now wound onto the roller, the cams g are turned off by rotating the shaft 8. the slot io moved, and .the paper tape is released. If the slot is selected to be appropriately large, the cross-section of the roller can be reduced by moving the two parts 5 and 6 against one another, as can be seen from FIG. 5, so that pulling out the roller is made even easier. However, it is useful to see. Stop surfaces 13 against which the part 6 of the roller strikes and which are dimensioned so that when the diameter of the roller is reduced, the slot still remains so wide that the end of the paper tape can be pulled out.
