Description

Die Erfindung betrifft eine Mehrbereichsschalteinrichtung mit einer umlaufenden, in der Drehzahl oder dem Zeitbereich veränderbaren Schaltscheibe, mit auf der Schaltscheibe angeordneten, insbesondere programmierbaren Schaltreiter zur Betätigung einer Schaltanordnung, mit einem umlaufenden Zifferblatt mit einer zeitbereichsbezogenen Skaleneinteilung und mit zwei in der Drehzahl zueinander verschiedener Antriebswellen, die wahlweise mit der Schaltscheibe kuppelbar sind, insbesondere für Zeitschalteinrichtungen.The invention relates to a multi-range switching device with a rotating switching disc that can be changed in terms of speed or time range, with switching tabs arranged on the switching disc, in particular programmable switching tabs for actuating a switching arrangement, with a rotating dial with a time range-related scale division and with two drive shafts that differ in speed from one another, which can optionally be coupled to the switching disc, especially for time switches.

Insbesondere für Zeitschalteinrichtungen, wie Schaltuhren Programmschaltwerke oder Zeitrelais, um nur einige zu nennen, ist es aus anwendungstechnischen, rationellen und wirtschaftlichen Gründen zweckmäßig und vorteilhaft, den jeweiligen anwendungsbedingten Zeitbereich bzw. die Drehzahl einer Schaltscheibe, insbesondere innerhalb des dort üblichen Tages-, Wochen-, Monats- oder Jahresprogrammzeitbereichs anwählen zu können. Dabei soll sichergestellt sein, daß die an derartigen Einrichtungen vorhandenen Mittel und Elemente hierfür ausreichend sind.In particular for time switch devices, such as time switches, program switching mechanisms or time relays, to name just a few, it is expedient and advantageous for application-related, rational and economic reasons to determine the respective application-related time range or the speed of a switching disc, in particular within the daily, weekly, To be able to select the monthly or annual program time range. It should be ensured that the means and elements present in such facilities are sufficient for this.

Es ist bekannt zur Erfüllung dieser Erfordernisse, insbesondere bei einer synchronmotorisch angetriebenen Schaltuhr, mit einem dort vorgesehenen Tages- und Wochenprogrammzeitbereich zwischen dem Antrieb und der Schaltscheibe ein mechanisches Umschaltgetriebe vorzusehen, mit welchem die Drehzahl der Schaltscheibe von 1 U/24h auf 1 U/Woche und umgekehrt verändert werden werden kann. Es ist dort jedoch erforderlich, daß zusätzlich zu dieser Getriebeumschaltung und unabhängig von dieser auf der Schaltscheibe ein Zifferblatt gewechselt d.h. auf den jeweiligen Zeitbereich abgestimmt werden muß (DE-A-2 835 518).It is known to meet these requirements, in particular in the case of a synchronous motor-driven time switch, with a daily and weekly program time range provided there between the drive and the switching disk, to provide a mechanical changeover gear with which the speed of the switching disk from 1 U / 24h to 1 U / week and vice versa can be changed. However, it is necessary there that in addition to this transmission changeover and independently of this, a dial on the switching disc is changed, i.e. must be matched to the respective time range (DE-A-2 835 518).

Diese bekannte Einrichtung ist nicht frei von Bedienungsfehlern, insbesondere durch die dort voneinander getrennte Handhabung von Getriebeumschaltung und Zifferblattwechsel. Außerdem ist es dort relativ kompliziert, wenn eine derart drehzahlumschaltbare Schaltscheibe zusätzlich zu einem, die Tageszeit anzeigenden, Zeigerwerk auf der Schaltuhr eingestellt werden soll.This known device is not free from operating errors, in particular due to the separate handling of gear change and dial change there. In addition, it is relatively complicated there if a switching disk which can be switched over in this way is to be set on the time switch in addition to a pointer mechanism which indicates the time of day.

Bei den, aus der DE-A-3 002 570 und der EP-A-0 051 262 (Stand der Technik gemäß Ast 54 (3) EPUe) bekanntgewordenen Ausführungen werden die vorgenannten Erfordernisse dadurch gelöst, daß eine einstückige Schaltscheibe auf der einen Seite als Tagesprogrammschaltscheibe und auf der anderen Seite als Wochenprogrammscheibe ausgebildet ist, und daß zum Wechseln des Zeitbereichs oder der Drehzahl die Schaltscheibe von der Schaltuhr abgenommen und umgewendet d.h. umgesteckt wird. Zum Eingriff mit dem Antrieb sind auf der Schaltscheibe, auf jeder Seite, entsprechende Zahnkränze vorgesehen, die mit einem Ritzel des Antriebs jeweils in Eingriff gebracht werden. Dabei ist der Zahnkranz für den Tages-Zeitbereich auf der Seite der Skaleneinteilung für den Wochen-Zeitbereich und der Zahnkranz für den Wochen-Zeitbereich ist auf der Seite der Skaleneinteilung für den Tages-Zeitbereich.In the versions known from DE-A-3 002 570 and EP-A-0 051 262 (state of the art according to branch 54 (3) EPUe), the aforementioned requirements are met in that a one-piece switching disc on one side is designed as a daily program switching disk and on the other side as a weekly program disk, and that the switching disk is removed from the time switch and turned over to change the time range or the speed, ie is repositioned. For engagement with the drive, corresponding gear rings are provided on the switching disk on each side, which are each brought into engagement with a pinion of the drive. The ring gear for the day-time range is on the scale division for the weekly time range and the ring gear for the weekly time range is on the scale division for the day-time range.

Diese Einrichtung erfüllt wohl die angestrebten Erfordernisse im wesentlichen, doch ist auch hier die Einstellung des jeweiligen Zeitbereichs, insbesondere zu einem die Tageszeit anzeigenden Zeigerwerk, bedingt durch die Zahnteilung der jeweiligen Zahnkränze zum zentralen Ritzel des Antriebs nicht einfach. Ausserdem muß dort die Schaltscheibe in ihrer justierten Lage zu einer Schaltanordnung verändert werden, was von Nachteil ist.This device probably fulfills the desired requirements essentially, but here too the setting of the respective time range, in particular for a pointer indicating the time of day, is not easy due to the tooth division of the respective ring gear to the central pinion of the drive. In addition, the switch position there must be changed in its adjusted position to a switching arrangement, which is a disadvantage.

Der Erfindung liegt die Aufgabe zugrunde, eine Mehrbereichsschalteinrichtung zu schaffen, bei der die Drehzahl einer Schaltscheibe und die entsprechende Zifferblattanzeige und Skaleneinteilung einfach und unverwechselbar genau gewechselt werden kann, ohne daß dabei die Schaltscheibe in ihrer örtlichen Lage, hinsichtlich ihres Eingriffsbereichs zu einer Schaltanordnung verändert werden muß. Außerdem soll sichergestellt sein, daß durch den Wechsel der Drehzahl bzw. des Zeitbereichs eine genaue und klar bezogene Einstellung zu einem vorgesehenen oder vorhandenen, analog anzeigenden Zeigerwerk gewährleistet ist.The invention has for its object to provide a multi-range switching device in which the speed of a switching disc and the corresponding dial display and scale division can be easily and unmistakably changed without changing the switching disc in its local position, with respect to its range of engagement to a switching arrangement got to. In addition, it should be ensured that the change in the speed or the time range ensures an accurate and clearly related setting to an intended or existing, analog indicating pointer mechanism.

Diese Aufgabe wird mit den Merkmalen im kennzeichnenden Teil des Patentanspruchs 1 gelöst.This object is achieved with the features in the characterizing part of patent claim 1.

Die in der Drehzahl zueinander verschiedenen Antriebswellen sind dort von einem zentralen Antrieb über entsprechende Getriebestufen in bekannter Weise abgezweigt.

In den Figuren sind gleiche oder einander entsprechende Bauteile mit gleichen Bezugszeichen versehen.In the figures, the same or corresponding components are the same Provide reference numerals.

Die in den Figuren 1 bis 3 dargestellte Einrichtung besteht im einzelnen aus einer Schaltscheibe 1, die auf einem drehharen, rohrartigen Lagerbolzen 3, nicht ortsveränderlich, angeordnet ist. 2 zeigt Schaltreiter, die schaltprogrammkonform am Umfang der Schaltscheibe 1 vorgesehen sind, und die mittels Schaltnacken 4, eine ortsfeste Schaltanorenung 5 betätigen.The device shown in Figures 1 to 3 consists in detail of a switching disc 1, which is arranged on a rotatable, tubular bearing pin 3, not moving. 2 shows shift tabs, which are provided in accordance with the shift program on the circumference of the shift disk 1 and which actuate a stationary shift arrangement 5 by means of shift necks 4.

Koaxial zum Lagerbolzen 3 sind zwei Antrieberohre 8 und 7 vorgesehen, die in der Drehzehl zueinander verschieden sind, und die, von einem nicht höher dargestellten, zentralen Antrieb, einem Synchronmotor, oder einem quertzgesteuerten Motor oder einem sonstigen geregelten Motor, über entsprechende Getriebestufen abgezweigt angetrieben sind Das Antriebsrohr 6 kann dort 1 U/24h und des Antriebsrohr 7 kann dort 1 U/Woche machen. Stirnseitig sind dort beide Antriebsrohre mit nockenartigen Kupplungsstücken 8 und 9 versehen.Coaxial to the bearing pin 3, two drive tubes 8 and 7 are provided, which are different from each other in the rotational speed, and which are driven in a branched manner by appropriate gear stages, from a central drive (not shown), a synchronous motor, or a cross-controlled motor or another regulated motor are the drive tube 6 there 1 U / 24h and the drive tube 7 there 1 U / week. On the face side, both drive tubes are provided with cam-like coupling pieces 8 and 9.

In der vorliegenden Ausführung steht das Kupplungsstück 8 des Antriebsrohren 6 in Eingrff mit einem enteprechend radial verlaufenden lückenartigen Kopplungsstück 10 an der Uniterseite 11 des Zifferblattes 12, der eigentlichen Kupplung zwischen dem Antrieb und der Schaltscheibe 1. Das Zifferblatt 12 ist mit der Schaltscheibe 1 über ein Kupplungsloch 13 am Zifferblatt 12, des mit einem entsprechenden Kupplungszapfen 14 an der Schaltscheibe 1 in Eingriff steht, gekuppelt. Die Schaltscheibe 1 macht bei dieser Kupplungskonstellation demnach 1 U/24h. Auf der Oberseite 15 des Zifferblattes 12 ist demnach eine 24h-Skaleneinteilung vorgesehen, wie in einer der folgenden Figuren noch näher sichtbaher ist.In the present embodiment, the coupling piece 8 of the drive tubes 6 engages with a corresponding radially extending gap-like coupling piece 10 on the lower side 11 of the dial 12, the actual coupling between the drive and the switching disk 1. The dial 12 is connected to the switching disk 1 via a Coupling hole 13 on the dial 12, which is engaged with a corresponding coupling pin 14 on the switching disc 1, coupled. The switching disc 1 makes 1 U / 24h in this clutch constellation. Accordingly, a 24-hour scale division is provided on the top 15 of the dial 12, as is more closely visible in one of the following figures.

Soll die Drehzahn der Schaltscheihe 1 nun auf 1 U/Woche umgeändert werden, dann wird zunächst die axialwirkende Begrenzungsmutter 1b auf dem ortsfesten Gewindebolzen 17 gelöst, das kupplungsartige Zifferblatt 12 wird von der Schaltscheibe 1 abgenommen und umgewendet und mit der Schaltscheibe 1, über das Kupplungsloch 13 und den Kupplungszapfen 14, wieder in Eingriff gebracht. Auf der bisherigen Oberseite 15 angeordnete lückenartige Kupplungsstücke 18, entsprechend radial angeordnet kommen nunmehr mit dem Antriebsrohr 7, mit den dort vorgesehenen Kupplungsstücken 9 in Eingriff. Die Begrenzungsmutter 18 wird wieder befestigt. Die Schaltscheibe 1 macht nunmehr bei dieser Kupplungskonstellation 1 U/Woche. auf der nunmehrigen Oberseite, der bisherigen Unterseite 11 ist eine Wochen-Skaleneinteilung vorgesehen.If the rotary tooth of the switching disc 1 is now to be changed to 1 rev / week, then the axially acting limiting nut 1b is first loosened on the fixed threaded bolt 17, the clutch-like dial 12 is removed from the indexing disc 1 and turned over and with the indexing disc 1 via the coupling hole 13 and the coupling pin 14, brought back into engagement. Gap-like coupling pieces 18 arranged on the previous upper side 15, correspondingly arranged radially, now come into engagement with the drive tube 7 with the coupling pieces 9 provided there. The limiting nut 18 is reattached. The switching disc 1 now makes 1 U / week in this clutch constellation. on the now upper side, the previous lower side 11, a weekly scale is provided.

Bei einer derartigen Einrichtung kann die Drehzahl einfach, unverwechselbar und sicher geändert werden, indem einfach das Zifferblatt 12 umgewendet wird, wobei dort auf jeder der beiden Oberflächen eine, der Drehzahl oder dem Zeitbereich einer Schaltscheibe 1 entsprechende Skaleneinteilung 19 für 1 U/24h, wie die Fig 2 zeigt, oder 1 U/Woche, wie die Fig. 3 zeigt. Außerdem ist dort immer eine definierte Lagenfixierung der Schaltscheibe 1 sowohl zum Zifferblatt 12 oder zum Antrieb, bzw. zu einem analoganzeigenden Zeigerwerk, gemäß der Darstellung in der Fig.3, gegeben, da nur eine einzige Kupplungsmölichkeit - Kupplungszapfen 14 zu Kupplungsloch 13 - pro 360° Umfang der Schaltscheibe 1 und des Zifferblattes 12 vorgesehen sind. Einstellfehler der Schaltscheibe 1 und/oder des Zifferblattes 12 zu einem Zeigerwerk 20 sind demnach ausgeschlossen. Eine definierte Lagensicherung ist damit gewährleistet.In such a device, the speed can be changed easily, unmistakably and safely, simply by turning the dial 12, there on each of the two surfaces a scale 19 corresponding to the speed or the time range of a switching disc 1 for 1 U / 24h, such as FIG. 2 shows, or 1 U / week, as FIG. 3 shows. In addition, there is always a defined position fixation of the switching disc 1 both to the dial 12 or to the drive, or to an analog indicating pointer, as shown in FIG. 3, since only a single coupling possibility - coupling pin 14 to coupling hole 13 - per 360 ° Scope of the switching disc 1 and the dial 12 are provided. Setting errors of the switching disc 1 and / or the dial 12 to a pointer 20 are therefore excluded. A defined position assurance is guaranteed.

Das analoganzeigende Zeigerwerk 20 ist dort vorteilhaft koaxial zur Schaltscheibe 1 und zum Zifferblatt 12 angeordnet. Das Zeigerwerk 20 kann unmittelbar mit dem zentralen Antrieb oder einem der Antriebsrohre 6 oder 7 in Eingriff stehen. Wird dort des Zeigerwerk 20 eingestellt drehen sich demnach auch die Schaltscheibe 1 mit dem Zifferblatt 12 und umgekehrt.The analog display pointer mechanism 20 is advantageously arranged coaxially with the switching disk 1 and the dial 12. The pointer mechanism 20 can directly engage the central drive or one of the drive tubes 6 or 7. If the pointer mechanism 20 is set there, the switching disc 1 with the dial 12 also rotates and vice versa.

Die in der Fig. 4 und 5 dargestellte Einrichtung besteht im einzelnen aus der Schaltscheibe 1, die wiederum auf einem drehbaren, rohrartigen Lagerbolzen 3, nicht ortsveränderlich, angeordnet ist. 2 bezeichnet wiederum Schaltreiter und 5 zeigt eine ortsfeste Schaltanordnung. Zur Kupplung der Schaltscheibe 1 mit dem Antrieb, insbesondere den hierfür vorgesehenen Gatrieberädern, oder -ritzel 21 und 22, ist dort die eigentliche Kupplung, das Zifferblatt 12, auf der Unterseite 11 und auf der Oberseite 15 jeweils mit einem einseitig gelagerten Zahnkranz 23 und 24 versehen. Beide Zahnkränze 23 und 24, die auf dem Zifferblatt 12 zueinander koaxial angeordnet sind, sind mit dem Zifferblatt 12 einstückig verbunden. Die Kupplung des Zifferblattes 12 mit der Schaltscheibe 1 erfolgt dort wiederum über das Kupplungsloch 13 und den Kupplungszapfen 14, die miteinander in Eingriff stehen.The device shown in FIGS. 4 and 5 consists in detail of the switching disc 1, which in turn is arranged on a rotatable, tubular bearing pin 3, not changing its position. 2 in turn designates switching tabs and FIG. 5 shows a fixed switching arrangement. For coupling the switching disc 1 to the drive, in particular the gear wheels or pinions 21 and 22 provided therefor, there is the actual coupling, the dial 12, on the underside 11 and on the top side 15, each with a gear ring 23 and 24 mounted on one side Mistake. Both sprockets 23 and 24, which are arranged coaxially on the dial 12, are integrally connected to the dial 12. The coupling of the dial 12 with the switching disc 1 takes place there again via the coupling hole 13 and the coupling pin 14, which are in engagement with one another.

In der gezeichneten Darstellung der Fig. 4 steht des Getrieberad 21 mit dem Zahnkranz 23 in Eingriff. Dieses Eingriffsverhältnis kann an der Schaltscheibe einer Drehzahl oder einem Zeitbereich von 1 U/24h entsprechen. Zwischen dem Getrieberad 21 und dem Zahnkrenz 23 kann insbesondere ein Übersetzungsverhältnis von 1:1 vorhanden sein. Auf der Oberseite 15 des Zifferblattes 12 ist gemäß der vorgenannten Drehzahl der Schaltscheibe 1 eine 24-stündige Skaleneinteilung 19 vorgesehen, wie die Fig. 5 näher zeigt. 16 bezeichnet wieder eine axial wirkende Begrenzungsmutter auf dem Gewindebolzen 17. Die Begrenzungsmutter 16 kann dort derart gestaltet sein, daß sie den jeweiligen Zahnkranz 23, 24 hutartig abdeckt.4, the gear wheel 21 engages with the ring gear 23. This engagement ratio on the switching disc can correspond to a speed or a time range of 1 U / 24h. A gear ratio of 1: 1 can in particular be present between the gear wheel 21 and the gear rim 23. On the top 15 of the dial 12, a 24-hour scale 19 is provided according to the aforementioned speed of the switching disc 1, as shown in FIG. 5. 16 again designates an axially acting limiting nut on the threaded bolt 17. The limiting nut 16 can there be designed such that it covers the respective ring gear 23, 24 like a hat.

Zur Änderung der Drehzahl oder des Zeitbereiches der Schaltscheibe 1 wird wiederum die Begrenzungsmutter 16 zunächst gelöst, das Zifferblatt 12 von der Schaltscheibe 1 abgenommen und umgewendet und wieder auf die Schaltscheibe 1 aufgesetzt und mit dieser über das Kupplungsloch 13 und den Kupplungszapfen 14 gekuppelt. Gleichzeitig mit dem Aufstecken des Zifferblattes 12 auf die Schaltscheibe 1 kam der Zahnkranz 24 mit dem Getrieberitzel 22 in Eingriff. Die Übersetzung des Getrieberitzels zum Zahnkranz 24 beträgt dort insbesondere 1:7, entsprechend einer Drehzahl oder einem Zeitbereich der Schaltscheibe 1 von 1 U/Woche. Das Getrieberad 21 und das Getrieberitzel 22 können dort auf einer gemeinsamen Antriebswelle angeordnet sein. Auf der nunmehrigen Oberseite des Zifferblattes, der bisherigen Unterseite 11, ist eine Wochen-Skaleneinteilung vorgesehen.To change the speed or the time range of the switching disc 1, the limiting nut 16 is again first loosened, the dial 12 is removed from the switching disc 1 and turned over and put back on the switching disc 1 and with it via the coupling hole 13 and Coupling pin 14 coupled. Simultaneously with the mounting of the dial 12 on the switching disc 1, the ring gear 24 came into engagement with the gear pinion 22. The translation of the gear pinion to the ring gear 24 there is in particular 1: 7, corresponding to a speed or a time range of the switching disc 1 of 1 U / week. The gear wheel 21 and the gear pinion 22 can be arranged there on a common drive shaft. On the now top of the dial, the previous underside 11, a weekly scale is provided.
