Description
Feststellvorrichtung für den Vorderanschlag an Pappscheren. Feststellvorrichtungen für den Vorderanschlag an Pappscheren, bei denen beide den Vorderanschlag tragenden Zahnstangen durch verschiebbare Glieder mit nur einer Schraube festgeklemmt werden, sind bekannt. Bei diesen bekannten Einrichtungen ist aber außer der Ritzelwelle noch eine zweite Klemmwelle oder Stange notwendig. Da Pappscheren zu den billigen Massenmaschinen gehören, so ist eine Vereinfachung und Verbilligung natürlich von besonderem Wert.Locking device for the front stop on cardboard scissors. Locking devices for the front stop on cardboard scissors, both of which carry the front stop Racks are clamped by sliding links with just one screw, are known. In these known devices, however, apart from the pinion shaft a second clamping shaft or rod is necessary. Because cardboard scissors are the cheap ones If mass machines belong, then a simplification and cheaper is of course of special value.
Die Erfindung sieht eine Feststellvorrichtung vor, bei welcher die Ritzelwelle selbst verschiebbar gelagert ist und einerseits einen festen Bund und anderseits eine achsial zur Ritzelwelle verschiebbare Scheibe trägt, die durch eine Schraube gegen die den Vorderanschlag tragenden Zahnstangen gepreßt werden. Dabei ist zur Vereinfachung die Einrichtung so getroffen, daß das Stellrad selbst als verschiebbare Scheibe ausgebildet ist.The invention provides a locking device in which the Pinion shaft itself is slidably mounted and on the one hand a fixed collar and on the other hand carries an axially displaceable disk to the pinion shaft, which by a Screw against the racks supporting the front stop are pressed. Included is to simplify the device made so that the adjusting wheel itself as slidable disc is formed.
Die Erfindung ist in den Anlagen dargestellt, und zwar ist alles Bekannte, was zum Verständnis der Erfindung nicht erforderlich ist, weggelassen.The invention is shown in the annexes, and everything is known, what is not necessary for understanding the invention is omitted.
Die Abbildung zeigt einen teilweisen Querschnitt durch die Stellvorrichtung.The figure shows a partial cross-section through the adjusting device.
Die Zahnstangen i und 2 tragen in bekannter Weise den nicht gezeichneten Vorderanschlag. Im Maschinengestell 3 ist die Ritzelwelle 4. gelagert und trägt, fest mit derselben verbunden, die Ritzel5 und 6. Mit der Welle q., unter Umständen mit dem Ritzel 6, gleich verbunden ist eine Scheibe 7. Auf der Ritzelwelle 4 achsial verschiebbar ist das Stellrad B. Die an dem Stellrad befindliche Knagge g kuppelt das Handrad mit der entsprechenden Knagge io an dem Ritzel 5, so daß das Stellrad 8 gegen Verdrehen gesichert ist. Mit einer Mutter i i kann das Handrad 8 auf der Welle q. verschoben werden. Bei dieser Verschiebung legt sich die Nabe des Handrades 8 gegen die Zahnstange i. Bei weiterem Anziehen der Mutter i i zieht sich die ganze Ritzelwelle weiter vor, bis sich die Scheibe 7 mit ihrer Seitenfläche gegen die Zahnstange 2, anlegt. Dadurch werden durch Vermittlung der Ritzelwelle q. die beiden Zahnstangen i und 2 gleichzeitig durch das Anziehen der Mutter i i festgeklemmt.The racks i and 2 carry the not shown in a known manner Front stop. The pinion shaft 4 is mounted in the machine frame 3 and carries, firmly connected to the same, the pinions 5 and 6. With the shaft q., under certain circumstances With the pinion 6, a disk 7 is connected in the same way. Axially on the pinion shaft 4 The adjusting wheel B is displaceable. The Knagge g located on the adjusting wheel is coupled the handwheel with the corresponding Knagge io on the pinion 5, so that the adjusting wheel 8 is secured against twisting. With a nut i i the handwheel 8 can be on the Wave q. be moved. With this shift, the hub of the handwheel lies down 8 against the rack i. With further tightening of the nut i i the whole pulls itself Pinion shaft continues until the disc 7 with its side surface against the Rack 2, applies. As a result, through the mediation of the pinion shaft q. the two Racks i and 2 clamped at the same time by tightening nut i i.
Anstatt das Handrad als Klemmscheibe zu benutzen, kann auch das Handrad auf das äußere Ende der Ritzelwelle q. festgemacht werden, während die Mutter und eine besondere Scheibe 8 auf der Welle verschiebbar angeordnet sind. Auch kann unter Umständen die YIutter i i in diesem Fall selbst mit einer großen Nabe versehen werden, so daß sie sich selbst gegen die Zahnstange i anlegt. Die einfachste und billigste Lösung dürfte aber die in der Figur abgebildete Ausführung sein.Instead of using the handwheel as a clamping disc, the handwheel on the outer end of the pinion shaft q. be moored while the mother and a special disc 8 are slidably arranged on the shaft. Also can under In this case, the YIutter i i can itself be provided with a large hub, so that it puts itself against the rack i. The simplest and cheapest However, the solution should be the version shown in the figure.
