Description

Die Erfindung betrifft einen Antrieb zum Betätigen von Türen oder Toren mit einem als Drehfeldmagnetmotor ausgebildeten Antrieb, wobei im Tür- oder Torbereich eine Sensoreinrichtung zur Beeinflussung des Antriebs vorgesehen ist.The invention relates to a drive for actuating doors or gates with a drive designed as a rotating field magnet motor, a sensor device for influencing the drive being provided in the door or gate area.

bei bekannten Tür- oder Torantrieben dieser Art kann beim Schließen des Tores durch die Sensoreinrichtung, meist eine Lichtschranke, beim Auftreten einer Störung, z.B. bei einer Unterbrechung der Lichtschranke, der Torantrieb angehalten oder in seiner Richtung umgekehrt und denn angehalten werden, bis die Störung verschwunden ist und noch anschließend eine gewisse Zeit abgelaufen ist. Alsdann wird der Antrieb wieder in Schließrichtung umgekehrt und das Tor geschlossen. Die das Tor beim Öffnen oder Schließen treibende Kraft bleibt hierbei weitgehend gleich. Sie ändert lediglich ihre Richtung.in known door or gate drives of this type, when the gate is closed by the sensor device, usually a light barrier, when a fault occurs, e.g. in the event of an interruption in the light barrier, the door drive is stopped or reversed in its direction and then stopped until the fault has disappeared and a certain time has passed. The drive is then reversed in the closing direction and the gate closed. The force driving the gate when opening or closing remains largely the same. It just changes direction.

Eine solche Einrichtung erweist sich jedoch als unzulänglich in anderen Situationen, wenn beispielsweise bei Feuergefahr oder einem ähnlichen Notfall aufgrund feuerpolizeilicher Vorschriften das Tor möglichst rasch mit hoher Schließkrgft (etwa 150 N) geschlossen werden soll, andererseits aber aufgrund von Unfallverhütungsvorschriften auch in einem solchen Fall noch verhindert werden muß, daß hierbei zwischen Tor- und Torrahmen eingeklemmte Objekte oder garPersonen verletzt werden. In diesem Fall ist es äußerst unerwünscht, wenn nach Entfernung des klemmenden Hindernisses das Tor bzw. sein Antrieb 'noch für die Dauer der sonst üblichen Sicherheitszeit bei geöffnetem Zustand angehalten wird. Auch versagen die vorbekannten sensorgesteuerten Torantriebe, wenn der Torwiderstand sich ändert, beispielsweise bei starkem Winddruck gegen das Tor vorübergehend sehr groß wird.However, such a device proves to be inadequate in other situations, for example if the door is to be closed as quickly as possible with a high closing force (approx. 150 N) in the event of a fire or a similar emergency due to fire regulations, but on the other hand still in such a case due to accident prevention regulations It must be prevented that objects or even people caught between the goal and goal frames are injured. In this case it is extremely undesirable if, after the jamming obstacle has been removed, the gate or its drive is still stopped for the duration of the otherwise usual safety time in the open state. The previously known sensor control also fail door drives if the door resistance changes, for example temporarily becomes very large when there is strong wind pressure against the door.

Der Erfindung liegt daher die Aufgabe zugrunde, den Torantrieb durch einfache Maßnahmen an die verschiedensten, denkbaren Belastungssituationen bei verschiednen Toren und Torwiderständen anzupassen, um sowohl das vorerwähnte Problem des möglichst raschen Schließens im Notfall bei größtmöglicher Sicherheit für in diesem Fall eventuell zwischen Tor und Torrahmen eingeklemmte Personen oder Objekte, als Dauch das Problem des Winddrucks, der das Öffnen und Schließen des Tores sehr erschwert, zu bewältigen.The invention is therefore the object of the door drive by simple measures to the most varied, conceivable load situations at various d nen gates and Torwiderständen adapt to both the aforementioned problem of the quickest possible closing in an emergency with the greatest possible security for in this case, possibly between gate and People or objects trapped in the gate frame to tackle the problem of wind pressure, which makes opening and closing the gate very difficult.

Die erfindungsgemäße Lösung dieser Aufgabe besteht darin, daß der für den Torantrieb vorgesehene Drehfeldmagnetmotor durch Ändern von Größe (einschl. des Vorzeichens) oder/und Phase der Spannung oder/ und des Stroms der einen, getrennt von den anderen aus dem Netz gespeisten Wicklung in seiner Drehzahl oder/und seinem Drehmoment regelbar ist.The solution to this problem according to the invention is that the rotary magnetic motor provided for the door drive by changing the size (including the sign) and / or phase of the voltage and / or the current of the one, separately from the other, fed from the network in its winding Speed or / and its torque is adjustable.

brehfeldmagnetmotore sind an sich bekannt. Bei ihnen werden zwei der drei Wicklungen, die auch mehrpolig ausgeführt werden können, in Serie geschaltet und in dieser Serienschaltung aus zwei Phasen des Drehstromnetzes gespeist, während die dritte separat von den beiden anderen aus der dritten Phase gespeist wird. Ihre Verwendung als TorAntrieb erfolgt hauptsächlich deswegen, weil bei ihnen die Stromaufnahme bei Stillstand nahezu gleich groß ist wie bei voller Drehzahl. Eine Regelung solcher Torantriebe ist bisher nicht durchgeführt worden, da die bisher hierfür bekannten Mittel, wie z.B. Regeltransformatoren, zu aufwendig und teurer als der Antriebsmotor sind. Durch die einfache und leichte erfindungsgemäße Art der Regelung des Antriebsmotors, bei der nur die Speisung einer einzigen der drei Motorwicklungen entsprechend beeinflußt werden muß, ergeben sich für den Antrieb stufenlose, beliebige Bewegungsmöglichkeiten.magnetic field motors are known per se. With them, two of the three windings, which can also be designed with multiple poles, are connected in series and fed in this series connection from two phases of the three-phase network, while the third is fed separately from the other two from the third phase. They are mainly used as gate drives because their power consumption at standstill is almost the same as at full speed. Regulation of such door drives has not been carried out to date, since the means known hitherto for this purpose, such as regulating transformers, are too complex and expensive than the drive motor. Due to the simple and easy way of regulating the drive motor according to the invention, in which only the supply of a single one of the three motors windings must be influenced accordingly, there are stepless, arbitrary movement possibilities for the drive.

Im Rahmen der Erfindung ist vorgesehen, daß die Sensoreinrichtung durch mehrere an verschiedenen Stellen vorgesehene Sensoren gebildet ist. Durch verschiedene Sensoren verschiedener Art an verschiedenen Stellen können mit Hilfe an sich bekannter Steuer- und Reglereinrichtungen und Mittel der elektronischen Rechnertechnik verschiedene gewünschte Bewegungen des Antriebs nach einem vorher festgelegten Programm ausgelöst werden. So ist der Motor je nach Sensor oder/und je nach Größe des vom Sensor abgeleiteten Signals auf verschiedene Drehzahlen bzw.Drehmomente regelbar.In the context of the invention it is provided that the sensor device is formed by several sensors provided at different locations. Various desired movements of the drive can be triggered according to a predetermined program by means of various sensors of different types at different locations with the aid of control and regulating devices known per se and means of electronic computer technology. Depending on the sensor and / or the size of the signal derived from the sensor, the motor can be regulated to different speeds or torques.

Bei einem Ausführungsbeispiel der Erfindung ist die Sensoreinrichtung durch druckabhängige, vorzugsweise im Bereich der Schließkante des Tores angeordnete Sensoren gebildet. Hierdurch besteht die Möglichkeit, im Notfall, wenn das Tor rasch geschlossen werden muß, beim Einklemmen eines Hindernisses zwischen Schließkante und Torrahmen das Tor anzuhalten oder zurückzuführen, aber auf jeden Fall beim Verschwinden des Hindernisses sofort und ohne Verzögerung die Schließbewegung fortzusetzen. Insbesondere kann die Regelung der Motordrehzahl in Abhängigkeit von der Größe des Druckes erfolgen,-beispielsweise proportional zu dem auf den oder die Sensoren ausgeübten Druck. Auch kann der Antrieb beispielsweise bei nur geringem Druck angehalten oder nur in seiner Bewegung oder seiner Schließkraft verändert werden und bei großem Druck kurzzeitig zurückgefahren werden, je nachdem für eine solche Situation vorgesehenen und vorher der Steuer-und Regeleinrichtung eingegebenen Programm. Gemäß einer besonderen Ausführungsform der Erfindung sind die druckabhängigen Sensoren hinter mindestens einer, vorzugsweise federnd gelagerten AndrUckleiste oder dgl. an der Schließkante des Tores oder der Türe angeordnet.In one embodiment of the invention, the sensor device is formed by pressure-dependent sensors, preferably arranged in the region of the closing edge of the door. This makes it possible, in an emergency, if the door has to be closed quickly, to stop or return the door when an obstacle is caught between the closing edge and the door frame, but in any case to continue the closing movement immediately and without delay when the obstacle disappears. In particular, the engine speed can be regulated as a function of the size of the pressure, for example proportional to the pressure exerted on the sensor or sensors. The drive can also be stopped, for example, at only a low pressure, or its movement or its closing force can only be changed and briefly retracted at high pressure, depending on the program provided for such a situation and previously entered into the control and regulating device. According to a special embodiment of the invention, the pressure-dependent sensors are arranged behind at least one, preferably resiliently mounted pressure strip or the like on the closing edge of the gate or door.

Um unabhängig von dem auf der Tür oder dem Tor lastenden Winddruck und dem dadurch bewirkten mehr oder minder großen, schwankenden Torwiderstand dennoch das Öffnen und Schließen des Tores mit stets gleichbleibender Geschwindigkeit ausführen zu können, ist in Weiterbildung der Erfindung vorgesehen, daß mindestens ein als Temperaturfühler ausgebildeter Sensor an einer windgeschützten Stelle und mindestens ein weiterer, ebenfalls als Temperaturfühler ausgebildeter Sensor an einer den Wind ausgesetzten Stelle im Torbereich vorgesehen ist und daß der Motor in Abhängigkeit von einem aus der Differenz der Signale der Temperaturfühler gebildeten Signal in seiner Leistung regelbar ist. Durch die Erfindung wird also der Winddruck festgestellt und in Abhängigkeit von diesem dem Motor zur Überwindung des hierdurch bewirkten Widerstands jeweils eine entsprechend große, für gleichmäßiges Öffnen und Schließen erforderliche Leistung zugeführt. Erfindungsgemäß wird hierbei die Winddruckmessung auf eine Temperaturmessung an einer windgeschützten und an einer dem Wind ausgesetzten Stelle zurückgeführt. An der dem Wind ausgestzten Stelle, wo die Luftbewegung herrscht, zeigt der Temperaturfühler eine geringere Temperatur an, als an der windgeschützten Stelle. Es wird also die Temperaturdifferenz an diesen beiden Stellen gemessen und aus der Temperaturdifferenz, die ein Maß für den Winddruck ist, dann eine Regelgröße für den Motor abgeleitet.In order to be able to carry out the opening and closing of the gate at a constant speed regardless of the wind pressure on the door or the gate and the resulting greater or lesser fluctuating gate resistance, a further development of the invention provides that at least one as a temperature sensor trained sensor at a wind-protected location and at least one further sensor, also designed as a temperature sensor, is provided at a location exposed to the wind in the gate area and that the motor's output can be regulated as a function of a signal formed from the difference between the signals of the temperature sensors. The invention therefore determines the wind pressure and, depending on this, supplies the motor with a correspondingly large power required for uniform opening and closing in order to overcome the resistance caused thereby. According to the invention, the wind pressure measurement is here traced back to a temperature measurement at a wind-protected location and at a location exposed to the wind. At the point exposed to the wind where there is air movement, the temperature sensor indicates a lower temperature than at the point protected from the wind. The temperature difference at these two points is measured and a control variable for the motor is then derived from the temperature difference, which is a measure of the wind pressure.

The invention is shown schematically in the drawing, for example. Show it:
  • 1: a view of a sliding gate,
  • Fig. 2: the circuit of a three-phase magnetic motor and
  • Fig. 3: an enlarged view of pressure sensors at the gate closing edge.

Figur 1 zeigt ein Beispiel eines Schiebetores 1, das an einem Torrahmen 2 beispielsweise mittels eines Seilzuges 3 in bekannter Weise durch einen nicht näher ausgeführten Antriebsmechanismus bewegt wird.Figure 1 shows an example of a sliding gate 1, which is moved on a goal frame 2, for example by means of a cable 3 in a known manner by a drive mechanism not shown.

Als Motor für den Antrieb des Tores 1 ist ein Drehfeldmagnetmotor vorgesehen, von dessen drei Wicklungen 4, 5 und 6, die auch mehrpolig ausgeführt sein können, zwei Wicklungen, nämlich 4 und 5, hintereinander geschaltet sind und in dieser Serienschaltung aus zwei Phasen des Drehstromnetzes gespeist werden, während der dritten Wickiung 6 separat und unabhängig von den beiden anderen die elektrische Energie aus der dritten Phase des Drehstromnetzes über eine Stromversorgungsschaltung 7 zugeführt wird.As a motor for driving the gate 1, a three-phase magnetic motor is provided, of whose three windings 4, 5 and 6, which can also be multi-pole, two windings, namely 4 and 5, are connected in series and in this series connection of two phases of the three-phase network be fed, while the third winding 6 separately and independently of the other two, the electrical energy from the third phase of the three-phase network is supplied via a power supply circuit 7.

Erfindungsgemäß sind Größe (einschl. des Vorzeichens) und/oder Phase der Spannung bzw. des Stroms, welcher der Wicklung 6 durch die Stromversorgungsschaltung 7 zugeführt wird, veränderbar, wodurch gewünschte Drehzahlen oder/und Drehmomente des Motors erzielt werden können. Die erforderlichen Signale zur Einstellung eines gewünschten Strom- bzw. Spannungsverlaufs in der Wicklung 6 erhält die Stromversorgung 7 über eine Steuerleitung 8 aus der Steuer- und Regeleinrichtung 9.According to the invention, the size (including the sign) and / or phase of the voltage or of the current which is supplied to the winding 6 by the power supply circuit 7 can be changed, as a result of which desired engine speeds and / or torques can be achieved. The power supply 7 receives the necessary signals for setting a desired current or voltage profile in the winding 6 via a control line 8 from the control and regulating device 9.

Um beispielsweise beim raschen Schließen des Tores 1 in einem Notfall (Ausbruch von Feuer) ein Einklemmen von Personen zu verhindern, sind an der Schließkante 10 des Tores 1 druckabhängige Sensoren 11 vorgesehen, die über eine oder mehrere davor angeordnete, hierdurch Federn 14 abgestützte Andrückleisten 12 (Figur 3) betätigbar sind. Die Sensoren können beliebiger Art sein, beispielsweise hydraulische Druckgeber, deren Kolben einen Schalter oder ein Potentiometer betätigt, aus dessen Stellung ein Signal abgeleitet wird, das einem der Eingänge 13 der Steuer- und Regeleinrichtung 9 zugeführt wird.In order, for example, to prevent people from getting caught in the event of an emergency (fire breaking out) when the door 1 closes quickly, pressure-dependent sensors 11 are provided on the closing edge 10 of the door 1, which are arranged via one or more pressure bars 12 arranged in front of it and thereby supported by springs 14 (Figure 3) can be actuated. The sensors can be of any type, for example hydraulic pressure transmitters, the pistons of which actuate a switch or a potentiometer, from the position of which a signal is derived which is fed to one of the inputs 13 of the control and regulating device 9.

Wird beispielsweise bei Feuergefahr (die z.B. durch einen Rouchmelder oder dgl. einem der Eingänge der Steuer- und Regeleinrichtung 9 angezeigt worden ist und über die Leitung 8 ein Stellsignal zum raschen Schließen des Tores ausgelöst hat) während des Schließens ein Hindernis an der Schließkante 10 eingeklemmt, bevor das Tor seine Endstellung erreicht hat, so wird durch den oder die hierdurch betätigten Druckgeber 11 ein entsprechendes Signal an einen oder mehrere der Eingänge 13 geliefert, das ein entsprechendes Stellsignal am Ausgang der Steuer- und Regeleinrichtung 9 bewirkt. Dieses löst ein für diesen Notfall gewünschtes Drehzahl- bzw. Drehmomentverhalten des Antriebsmotors und damit eine gewünschte Bewegung des Tores hinsichtlich Geschwindigkeit und Schließkraft aus.For example, if there is a risk of fire (caused, for example, by a smoke alarm or the like. One of the inputs of the control and regulating device 9 has been displayed and has triggered an actuating signal via line 8 for the rapid closing of the door), an obstacle being clamped on the closing edge 10 during the closing before the door has reached its end position, so a corresponding signal is delivered to one or more of the inputs 13 by the pressure transmitter (s) actuated thereby, which causes a corresponding actuating signal at the output of the control and regulating device 9. This triggers a desired speed or torque behavior of the drive motor for this emergency and thus a desired movement of the door with regard to speed and closing force.

Durch entsprechende, vorher der Einrichtung 9 eingegebene Programme können je nach Art oder Zahl des oder der jeweils betätigten Sensoren oder je nach der jeweiligen Sensorsignalgröße verschiedene Bewegungsmögliehkeiten des Tores vorgesehen werden. beispielsweise kann bei geringem Druck an der Schließkante (kleines Sensorsignal) das Tor nur kurz angehalten und dann weiter in die Schließstellung, eventuell mit verminderter Schließkraft, gefahren werden. Beim Auftreten eines stärkeren Drucks kann ein kurzes Zurückfahren und dann eine erneute Schließbewegung vorgesehen sein.By means of corresponding programs previously entered into the device 9, different movement possibilities of the gate can be provided depending on the type or number of the sensor or sensors actuated or on the respective sensor signal size. For example, at low pressure at the closing edge (small sensor signal), the door can only be stopped briefly and then moved to the closed position, possibly with reduced closing force. If a higher pressure occurs, a brief retraction and then a new closing movement can be provided.

An die Eingänge 13 der Steuer- und Regeleinrichtung 9 können verschiedenartige Sensoren angeschaltet sein. So können beispielsweise einem Eingang das oder die Signale eines oder mehrerer Druckgeber zugeführt werden, einem anderen das Ausgangssignal einer Lichtschranke und einem weiteren etwa die Differenz aus dem Signal eines an der Oberseite des Tores 2 angeordneten, dem Wind ausgesetzten Temperaturfühler 15 und dem Signal eines nicht näher dargestellten, an einer windgeschützten Stelle vorgesehenen zweiten Temperaturfühlers, wie oben bereits beschrieben.Various types of sensors can be connected to the inputs 13 of the control and regulating device 9. For example, the input or signals of one or more pressure transmitters can be supplied to an input, another the output signal of a light barrier and another approximately the difference between the signal of a temperature sensor 15 arranged on the top of the gate 2 and exposed to the wind and the signal one not shown in more detail, provided at a wind-protected location second temperature sensor, as already described above.

Durch die einfache erfindungsgemäße Regelung durch Ändern von Größe oder/und Phase des Stroms bzw. der Spannung der einen Wicklung des Motors wird es also möglich, durch Eingabe entsprechender Bewegungsprogramme in die Steuer- und Regieinrichtung 9 beim Ansprechen verschiedener Sensoren und beim Auftreten verschiedener, auch unterschiedlich großer Sensorsignale verschiedene, für den jeweiligen Fall gewünschte Bewegungen des Tores 1 zu erzielen.The simple control according to the invention by changing the size or / and phase of the current or the voltage of the one winding of the motor thus makes it possible, by inputting appropriate movement programs into the control and regulating device 9 when different sensors respond and when different ones occur sensor signals of different sizes to achieve different movements of the gate 1 desired for the respective case.

Im einfachsten Fall kann durch Umkehr der Phase des Stroms in der Wicklung 6 die Drehrichtung des Motors und damit die Bewegungsrichtung des Antriebs umgekehrt werden. Durch Verändern der Größe des Stroms kann die Drehzahl von einem Maximalwert bis auf Null heruntergeregelt werden.In the simplest case, the direction of rotation of the motor and thus the direction of movement of the drive can be reversed by reversing the phase of the current in the winding 6. By changing the size of the current, the speed can be reduced from a maximum value to zero.
