Description

Notorischer Antrieb von langsam verlaufenden Umschaltvorgängen In der Meß- und Schalttechnik wird häufig für die Betätigung langsam verlaufender Vorgänge ein motorischer Antrieb von geringer Leistung benötigt. Der rasch laufende Elektromotor ist zum direkten Antrieb hier nicht geeignet und arbeitet jentweder über ein Räderwerk mit entsprechenden Übersetzungen, oder er wirddurch ein geeignetes Schaltwerk von Zeit zu Zeit nur kurzzeitig eingeschaltet. BeideMetho#den erfordern einen verhältnismäßig komplizierten Mechanismus, ein Umstan#d.. der besonders dort Schwierigkeiten bereitet, wo der Antrieb jahrelang ohne Wartung arbeiten soll.Notorious drive for slow switching processes In measurement and switching technology, a low-power motor drive is often required for the actuation of slow processes. The fast-running electric motor is not suitable for direct drive here and either works via a gear train with appropriate gear ratios, or it is only switched on briefly from time to time by a suitable switching mechanism. Both methods require a relatively complex mechanism, a circumstance that is particularly difficult where the drive is to work for years without maintenance.

Es sind bereits Wechselstrommotoren für den Antrieb eines Zeitzählers oder zur Kupplung eines Maximumzählers mit einem Kontaktwerk verwendet worden, und andererseits ist eine Einrichtung bekannt geworden, bei der ein Motor jedesmal nach einer vollen Umdrehung einer durch den Motor angetriebenen Steuerscheibe selbsttätig abgeschaltet wird.There are already AC motors to drive a timer or used to couple a maximum counter with a contact mechanism, and on the other hand, a device has become known in which an engine is every time one full revolution of a control disk driven by the motor is switched off.

Von derartigen Einrichtungen unterscheidet sich der Erfindungsgegenstand einerseits durch das Anwendungsgebiet und andererseits dadurch, daß ein Asynchronmotor, der in an sich bekannter Weise so bemessen ist, daß er sich unter voller Spannung beliebig langsam drehen oder ganz stillstehen kann, dauernd unter Strom steht. Er ist mit einer Hemmung derart verbunden, daß nach elektromagnetischer Auslösung der Hemmung der Motor für kurze Zeit bis zum Wiedereinfallen der Hemmung freigegeben wird.The subject matter of the invention differs from such devices on the one hand by the field of application and on the other hand by the fact that an asynchronous motor, which is measured in a manner known per se so that it is under full tension can turn as slowly as you like or stand still completely, is permanently energized. He is associated with an inhibition in such a way that after electromagnetic release of the Inhibition of the motor is released for a short time until the inhibition is re-applied will.

Zur näheren Erläuterung soll folgendes Beislyiel dienen: Bei einem Registrierinstrument mit Punktaufzeichnung soll der Fallbügel i alle 30 Sekunden den Zeiger 2 auf den Papierstreifen 3 drücken. Diese Betätigung soll durch die Stromirnpulse einer elektrischen Zentraluhr erfolgen, deren Arbeitsinhalt jedoch nicht ausreicht, den Fallbügel zu heben. Es ist daher ein Asynchronmotor vorgesehen, von dem in der Abbildung nur die Welle 4 dargestellt ist, der eine Scheibe 5 in der angegebenen Pfeilrichtun#g zu drehen versucht und hieran durch ein Gesperre 6 gehindert wird. Letzteres wird idurch einen Magneten 7 vom Strom ,der Zentraluhr zeitweise kurz gelöst, der Motor kann dann eine Umdrehung ausführen und wird wieder -,durch das Gesperre6 stillgesetzt. Bei dieser einen Umdrehung betätigt der Motor durch die auf der Scheibe 5 exzentrisch angelenkte Stange 8 den Fallbügel i, Es ist also bei diesem motorischen Antrieb jedes Räder- und Schaltwerk vermieden.The following example should serve for a more detailed explanation: In the case of a recording instrument with point recording, the drop arm i should press the pointer 2 onto the paper strip 3 every 30 seconds. This actuation should be carried out by the current impulses of an electrical central clock, the work content of which, however, is not sufficient to lift the drop bracket. An asynchronous motor is therefore provided, of which only the shaft 4 is shown in the figure, which attempts to rotate a disk 5 in the indicated arrow direction and is prevented from doing so by a locking mechanism 6. The latter is temporarily briefly released from the current by a magnet 7 of the central clock, the motor can then perform one revolution and is stopped again by the locking mechanism6. During this one revolution, the motor actuates the drop bracket i through the rod 8 which is eccentrically articulated on the disk 5.
