The present invention relates to an actuator unit with a basic actuator, an additional actuator and a drive unit,
  • wherein by means of the actuators a useful circuit can be opened and closed and the useful circuit is opened as soon as at least one of the actuators is deactivated,
  • wherein the basic actuator can be activated when properly functioning by supplying electrical energy and can be deactivated by non-supply of electrical energy,
  • wherein the drive unit is supplied with an actual activation state of the basic actuator,
  • wherein the drive unit deactivates the additional actuator when the actual activation state of the basic actuator deviates from a desired activation state of the basic actuator,
  • wherein the additional actuator can be deactivated by supplying electrical energy and the drive unit only deactivates the additional actuator when the actual activation state of the basic actuator deviates from the desired activation state of the basic actuator.

Eine derartige Aktoreinheit ist z. B. aus der WO 96/42098 A oder der DE 29 20188 B2 bekannt.Such an actuator is z. B. from WO 96/42098 A or DE 29 20188 B2.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Aktoreinheit derart auszugestalten, dass auch der Zusatzaktor auf ordnungsgemäßes Funktionieren überprüfbar ist.The object of the present invention is to design an actuator unit in such a way that the additional actuator can also be checked for proper functioning.

Die Aufgabe wird dadurch gelöst, dass der Zusatzaktor durch Zufuhr elektrischer Energie aktivierbar ist und der Ansteuereinheit ein Ist-Aktivierungszustand des Zusatzaktors zugeführt wird.The object is achieved in that the additional actuator can be activated by supplying electrical energy and the drive unit, an actual activation state of the additional actuator is supplied.

Vorzugsweise wird der Ist-Aktivierungszustand des Grundaktors, evtl. auch der Ist-Aktivierungszustand des Zusatzaktors, an eine der Ansteuereinheit übergeordnete Einheit gemeldet.The actual activation state of the basic actuator, possibly also the actual activation state of the additional actuator, is preferably reported to a higher-level unit of the control unit.

Der Grundaktor kann über die Ansteuereinheit aktiviert und deaktiviert werden. Alternativ ist auch eine direkte Ansteuerung des Grundaktors über eine übergeordnete Einheit möglich.The basic actuator can be activated and deactivated via the control unit. Alternatively, a direct control of the basic actuator via a higher-level unit is possible.

Die Ansteuereinheit kann permanent mit elektrischer Energie versorgt werden. Alternativ ist es auch möglich, daß die Ansteuereinheit nur dann mit elektrischer Energie versorgt wird, wenn der Soll-Aktivierungszustand des Grundaktors einem aktivierten Grundaktor entspricht. In diesem Fall muß die Ansteuereinheit bei einer Deaktivierung des Grundaktors über einen Energiepuffer kurzfristig weiter mit Energie versorgt werden. Der Energiepuffer muß dabei selbstverständlich derart ausgelegt sein, daß bei einer Deaktivierung des Grundaktors noch eine Überprüfung des Grundaktors auf Deaktivierung und gegebenenfalls eine Deaktivierung des Zusatzaktors möglich ist.The drive unit can be permanently supplied with electrical energy. Alternatively, it is also possible that the drive unit is supplied with electrical energy only when the desired activation state of the basic actuator corresponds to an activated basic actuator. In this case, the drive unit must be supplied with a deactivation of the basic actuator via an energy buffer in the short term with energy. The energy buffer must of course be designed so that when the basic actuator is deactivated, it is still possible to check the basic actuator for deactivation and possibly deactivate the additional actuator.

Die Aktoreinheit ist besonders kompakt aufgebaut, wenn der Grundaktor, der Zusatzaktor und die Ansteuereinheit in einem gemeinsamen Gehäuse angeordnet sind.The actuator unit has a particularly compact design when the basic actuator, the additional actuator and the drive unit are arranged in a common housing.

Wenn das Gehäuse den Grundaktor, den Zusatzaktor und die Ansteuereinheit in hoher Schutzart abkapselt, ist die Aktoreinheit auch in spritzwasserhaltiger und staubbelasteter Umgebung einsetzbar. "Hohe Schutzart" bedeutet dabei Schutz mindestens nach IP 54, besser nach IP 65, evtl. sogar nach IP 67.If the housing encapsulates the basic actuator, the additional actuator and the control unit in a high degree of protection, the actuator unit can also be used in a splash-containing and dust-laden environment. "High degree of protection" means protection at least to IP 54, better to IP 65, possibly even to IP 67.

Wenn die Aktoreinheit Steckverbinder zum Verbinden des Grundaktors und des Zusatzaktors mit dem Nutzkreis und zum Zuführen elektrischer Energie zum Grundaktor, zum Zusatzaktor und zur Ansteuereinheit aufweist, ist die externe Verdrahtung der Aktoreinheit sehr schnell zu bewerkstelligen. Die Steckverbinder sind vorzugsweise von außerhalb des Gehäuses zugänglich.If the actuator unit has connectors for connecting the basic actuator and the additional actuator to the user circuit and for supplying electrical energy to the basic actuator, to the additional actuator and to the drive unit, the external wiring of the actuator unit can be accomplished very quickly. The connectors are preferably accessible from outside the housing.

Wenn die Steckverbinder Haltevorrichtungen zum Sichern von mit den Steckverbindern verbundenen Gegensteckverbindern und/oder von auf die Steckverbinder aufgesetzten Abdeckungen aufweisen, arbeitet die Aktoreinheit besonders zuverlässig.If the connectors have holding devices for securing mating connectors connected to the connectors and / or covers placed on the connectors, the actuator unit operates particularly reliably.

Weitere Vorteile und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispiels. Dabei zeigen in Prinzipdarstellung dieFurther advantages and details emerge from the following description of an embodiment. This show in a schematic representation of the

FIG 1 und 2 je eine Aktoreinheit.1 and 2 each have an actuator.

Gemäß FIG 1 weist eine Aktoreinheit einen Grundaktor 1, einen Zusatzaktor 2 und eine fehlersichere Ansteuereinheit 3 auf. Mittels der Aktoren 1, 2 ist ein Nutzkreis 4 öffen- und schließbar. Der Nutzkreis 4 wird geöffnet, sobald mindestens einer der Aktoren 1, 2 deaktiviert wird.According to FIG. 1, an actuator unit has a basic actuator 1, an additional actuator 2 and a fail-safe drive unit 3. By means of the actuators 1, 2 is a Nutzkreis 4 can be opened and closed. The user circle 4 is opened as soon as at least one of the actuators 1, 2 is deactivated.

Der Grundaktor 1 ist von einer fehlersicheren Steuerung 5 aus über Relais 6 und Versorgungsleitungen 7 mit elektrischer Energie versorgbar. Bei ordnungsgemäßem Funktionieren des Grundaktors 1 ist dieser durch Zufuhr elektrischer Energie aktivierbar und durch Nichtzufuhr elektrischer Energie deaktivierbar. Der Grundaktor 1 kann z. B. als Schütz bzw. Relais ausgebildet sein.The basic actuator 1 can be supplied with electrical energy from a fail-safe controller 5 via relays 6 and supply lines 7. With proper functioning of the basic actuator 1 this can be activated by supplying electrical energy and deactivated by not supplying electrical energy. The basic actuator 1 may, for. B. be designed as a contactor or relay.

Der Zusatzaktor 2 hingegen ist durch Zufuhr elektrischer Energie deaktivierbar. Z. B. kann der Zusatzaktor 2 als elektrischer Leistungsschalter ausgebildet sein. Der Zusatzaktor 2 ist derart ausgebildet, daß er durch Zufuhr elektrischer Energie auch wieder aktivierbar ist. Dieser ist als bistabiles Element, sozusagen als bistabiler elektrischer Leistungsschalter, ausgebildet.The additional actuator 2, however, can be deactivated by supplying electrical energy. For example, the additional actuator 2 may be formed as an electrical power switch. The additional actuator 2 is designed such that it can also be activated again by supplying electrical energy. This is designed as a bistable element, so to speak as a bistable electrical circuit breaker.

Gemäß FIG 1 ist der Nutzkreis 4 ein elektrischer Nutzkreis. Alternativ könnte der Nutzkreis 4 aber auch ein hydraulischer oder pneumatischer Nutzkreis sein. In diesem Fall wären die Aktoren 1, 2 als als hydraulische bzw. pneumatische Magnetventile ausgebildet.According to FIG 1, the Nutzkreis 4 is an electrical Nutzkreis. Alternatively, the Nutzkreis 4 but could also be a hydraulic or pneumatic circuit. In this case, the actuators 1, 2 would be designed as hydraulic or pneumatic solenoid valves.

Eine an den Versorgungsleitungen 7 anstehende Versorgungsspannung U wird von der Ansteuereinheit 3 abgegriffen. Der Grundaktor 1 wird dadurch auf Zufuhr elektrischer Energie überwacht. Wenn die Versorgungsspannung U eine Grenzspannung überschreitet, ermittelt die Ansteuereinheit 3 als Soll-Aktivierungszustand des Grundaktors 1, daß dieser aktiviert werden soll. Anderenfalls ermittelt die Ansteuereinheit 3 als Soll-Aktivierungszustand des Grundaktors 1 einen deaktivierten Grundaktor 1. Die Ansteuereinheit 3 ermittelt also aus der Zufuhr elektrischer Energie zum Grundaktor 1 den Soll-Aktivierungszustand des Grundaktors 1.A voltage applied to the supply lines 7 supply voltage U is tapped by the drive unit 3. The basic actuator 1 is thereby monitored for the supply of electrical energy. When the supply voltage U exceeds a threshold voltage, the drive unit 3 determines, as the desired activation state of the basic actuator 1, that this should be activated. Otherwise, the drive unit 3 determines the target activation state of the basic actuator 1 as a set activation state of a deactivated basic actuator 1. The drive unit 3 thus determines the desired activation state of the basic actuator 1 from the supply of electrical energy to the basic actuator 1.

Der Ansteuereinheit 3 wird ferner ein Ist-Aktivierungszustand des Grundaktors 1 zugeführt. Dies kann beispielsweise, wie in FIG 1 dargestellt, dadurch geschehen, daß dem Grundaktor 1 ein zwangsgeführter Schalter 8 zugeordnet ist, der zusammen mit der Betätigung des Grundaktors 1 geschaltet wird. Alternativ könnte beispielsweise auch der Schaltzustand des Nutzkreises 4 überwacht werden.The drive unit 3 is further supplied with an actual activation state of the basic actuator 1. This can be done, for example, as shown in FIG 1, characterized in that the basic actuator 1 is assigned a positively driven switch 8, which is connected together with the operation of the basic actuator 1. Alternatively, for example, the switching state of the Nutzkreises 4 could be monitored.

Die Ansteuereinheit 3 vergleicht den Ist-Aktivierungszustand des Grundaktors 1 mit dem Soll-Aktivierungszustand des Grundaktors 1. Weichen die Aktivierungszustände voneinander ab, deaktiviert die Ansteuereinheit 3 den Zusatzaktor 2. Erfindungsgemäß bleibt der Zusatzaktor 2 aber aktiviert, wenn der Grundaktor 1 ordnungsgemäß deaktiviert wird. Der Zusatzaktor 2 wird also nur dann deaktiviert, wenn der Ist-Aktivierungszustand des Grundaktors 1 vom Soll-Aktivierungszustand des Grundaktors 1 abweicht.The activation unit 3 compares the actual activation state of the basic actuator 1 with the desired activation state of the basic actuator 1. If the activation states deviate from one another, the activation unit 3 deactivates the additional actuator 2. According to the invention, the additional actuator 2 remains activated when the basic actuator 1 is properly deactivated. The additional actuator 2 is thus deactivated only when the actual activation state of the basic actuator 1 deviates from the desired activation state of the basic actuator 1.

Gemäß FIG 1 ist dem Zusatzaktor 2 analog zum Grundaktor 1 ein Zusatzschalter 9 zugeordnet, der zusammen mit dem Zusatzaktor 2 geschaltet wird. Der Schaltzustand des Zusatzschalters 9 und damit der Ist-Aktivierungszustand des Zusatzaktors 2 wird ebenfalls der Ansteuereinheit 3 zugeführt. Die Ist-Aktivierungszustände des Grundaktors 1 und des Zusatzaktors 2 können somit, wie in FIG 1 gestrichelt angedeutet, an die fehlersichere Steuerung 5 oder eine andere übergeordnete Einheit 10 gemeldet werden.According to FIG. 1, the additional actuator 2 is assigned, analogously to the basic actuator 1, an additional switch 9 which is switched together with the additional actuator 2. The switching state of the additional switch 9th and thus the actual activation state of the additional actuator 2 is also supplied to the drive unit 3. The actual activation states of the basic actuator 1 and the additional actuator 2 can thus, as indicated by dashed lines in FIG. 1, be reported to the fail-safe controller 5 or another superordinate unit 10.

Gemäß FIG 1 wird der Grundaktor 1 direkt von der sicheren Steuerung 5 aus aktiviert und deaktiviert. Alternativ könnte der Grundaktor 1 aber auch über die Ansteuereinheit 3 aktiviert und deaktiviert werden.According to FIG. 1, the basic actuator 1 is activated and deactivated directly from the safe control 5. Alternatively, the basic actuator 1 could also be activated and deactivated via the drive unit 3.

Gemäß FIG 1 wird die Ansteuereinheit 3 nur dann mit elektrischer Energie versorgt, wenn der Soll-Aktivierungszustand des Grundaktors 1 einem aktivierten Grundaktor 1 entspricht. Daher ist der Ansteuereinheit 3 ein Energiepuffer 12 zugeordnet, z. B. ein Speicherkondensator 12. Mittels des Energiepuffers 12 ist bei einer Deaktivierung des Grundaktors 1 die Ansteuereinheit 3 kurzfristig weiter mit Energie versorgbar. Der Energiepuffer 12 ist dabei derart dimensioniert, daß die Ansteuereinheit 3 bei einer Soll-Deaktivierung des Grundaktors 1 eine Abweichung des Ist-Aktivierungszustands des Grundaktors 1 noch feststellen und den Zusatzaktor 2 deaktivieren kann. Alternativ wäre es aber auch möglich, die Ansteuereinheit 3 über Hilfsanschlüsse permanent mit elektrischer Energie zu versorgen.According to FIG. 1, the drive unit 3 is supplied with electrical energy only when the desired activation state of the basic actuator 1 corresponds to an activated basic actuator 1. Therefore, the drive unit 3 is associated with an energy buffer 12, z. B. a storage capacitor 12. By means of the energy buffer 12, the drive unit 3 is briefly supplied with energy at a deactivation of the basic actuator 1. The energy buffer 12 is dimensioned such that the drive unit 3 still detect a deviation of the actual activation state of the basic actuator 1 at a target deactivation of the basic actuator 1 and can deactivate the additional actuator 2. Alternatively, it would also be possible to supply the drive unit 3 via auxiliary terminals permanently with electrical energy.

Wie aus FIG 1 ferner ersichtlich ist, sind die Aktoren 1, 2 und die Ansteuereinheit 3 in einem gemeinsamen Gehäuse 11 angeordnet. Dadurch ist die Aktoreinheit als Einheit montier- und demontierbar.As is also apparent from FIG. 1, the actuators 1, 2 and the drive unit 3 are arranged in a common housing 11. As a result, the actuator unit can be assembled and disassembled as a unit.

Aufgrund der Eigenüberwachung der Aktoreinheit ist es möglich, die Ansteuerung des Grundaktors 1 durch die Steuerung 5 einkanalig auszugestalten. Dennoch kann die höchste Sicherheitskategorie 4 der Europäischen Norm EN 954-1 eingehalten werden.Due to the self-monitoring of the actuator, it is possible to design the control of the basic actuator 1 by the controller 5 single-channel. Nevertheless, the highest safety category 4 of the European standard EN 954-1 can be complied with.

FIG 2 zeigt nun die mechanisch-konstruktive Ausgestaltung der Aktoreinheit von FIG 1.2 now shows the mechanical construction of the actuator unit of FIG. 1

Gemäß FIG 2 ist das Gehäuse 11 als Gehäuse 11 hoher Schutzart ausgebildet, mittels dessen der Grundaktor 1, der Zusatzaktor 2 und die Ansteuereinheit 3 sowie die Schalter 8, 9 von der Umgebung abkapselt werden. "Hohe Schutzart" bedeutet dabei Schutz mindestens nach Schutzart IP 54, besser nach Schutzart IP 65, evtl. sogar nach Schutzart IP 67.According to FIG 2, the housing 11 is formed as a housing 11 high degree of protection, by means of which the basic actuator 1, the additional actuator 2 and the drive unit 3 and the switches 8, 9 are encapsulated by the environment. "High degree of protection" means protection at least according to degree of protection IP 54, better according to degree of protection IP 65, possibly even according to degree of protection IP 67.

Die Aktoreinheit weist gemäß FIG 3 Steckverbinder 13 bis 15 auf. Die Steckverbinder 13 bis 15 sind von außerhalb des Gehäuses 11 zugänglich. Mittels der Steckverbinder 13 sind der Grundaktor 1 und der Zusatzaktor 2 mit dem Nutzkreis 4 verbindbar. Mittels des Steckverbinders 14 ist dem Grundaktor 1, dem Zusatzaktor 2 und der Ansteuereinheit 3 elektrische Energie zuführbar. Mittels der Steckverbinder 15 sind der Ansteuereinheit 3 weitere Signale, z. B. Notaussignale, zuführbar.The actuator unit has according to FIG 3 connectors 13 to 15. The connectors 13 to 15 are accessible from outside the housing 11. By means of the plug connectors 13, the basic actuator 1 and the additional actuator 2 can be connected to the user circuit 4. By means of the connector 14 is the basic actuator 1, the additional actuator 2 and the drive unit 3 electrical energy supplied. By means of the connector 15 of the drive unit 3 are further signals, z. B. emergency signals, fed.

Den Steckverbindern 13 sind Verriegelungshebel 16 zugeordnet. Dem Steckverbinder 14 sind Gewindebohrungen 17 zugeordnet. Die Steckverbinder 15 sind mit Schraubgewinden 18 versehen. Die Verriegelungshebel 16, die Gewindebohrungen 17 und die Schraubgewinde 18 bilden Haltevorrichtungen 16 bis 18. Mit ihnen sind nicht dargestellte, mit den Steckverbindern 13 bis 15 verbundene Gegensteckverbinder und/oder nicht dargestellte, auf die Steckverbinder 13 bis 15 aufgesetzte Abdeckungen gegen versehentliches Lösen sicherbar.The connectors 13 are assigned locking lever 16. The connector 14 threaded holes 17 are assigned. The connectors 15 are provided with screw threads 18. The locking lever 16, the threaded holes 17 and the screw thread 18 form holding devices 16 to 18. With them are not shown, connected to the connectors 13 to 15 mating connector and / or not shown, on the connectors 13 to 15 patch covers against accidental loosening secured.

Das Versehen des Gehäuses 11 mit den Steckverbindern 13 bis 15 und auch das Zuordnen der Haltevorrichtungen 16 bis 18 zu den Steckverbindern 13 bis 15 ist selbstverständlich unabhängig vom Vorhandensein und von der Ausbildung des Gehäuses 11 als Gehäuse 11 hoher Schutzart möglich.The provision of the housing 11 with the connectors 13 to 15 and also the assignment of the holding devices 16 to 18 to the connectors 13 to 15 is of course possible regardless of the presence and of the formation of the housing 11 as a housing 11 high degree of protection.
