Abstract

1. Drive means for actuating doors or gates (1) with a polyphase a.c. motor (4, 5, 6) wherein a sensor device (11) for influencing the drive means is provided in the region of the door or gate and the motor (4, 5, 6) can be regulated as regards its rotational speed or torque by altering the magnitude and/or phase of the voltage and/or current in at least one winding (6) fed separately from the others from the power circuit, characterised in that at least one sensor designed as a temperature sensor is provided at a point shielded from the wind, and at least one further sensor, likewise designed as a temperature sensor (11), is provided at a point in the region of the door or gate exposed to the wind, and that the motor (4, 5, 6) can be adjusted as regards its rotational speed according to a signal formed from the difference in the signals from the temperature sensors.

Description

Die Erfindung betrifft einen Antrieb zum Betätigen von Türen oder Toren mit einem Mehrphasen-Wechselstrommotor, wobei im Tür- oder Torbereich eine Sensoreinrichtung zur Beeinflussung des Antriebs vorgesehen ist, und der Motor durch Ändern von Größe oder/und Phase der Spannung oder/und des Stroms in mindestens einer, getrennt von den anderen aus dem Netz gespeisten Wicklung in seiner Drehzahl oder/und seinem Drehmoment regelbar ist.The invention relates to a drive for actuating doors or gates with a multi-phase AC motor, a sensor device for influencing the drive being provided in the door or gate area, and the motor by changing the size or / and phase of the voltage and / or the current in at least one, separately from the other windings fed from the network, its speed and / or its torque can be regulated.

Eine solche Anordnung ist beispielsweise aus der DE-A 2 405 281 bekannt. Hier sind als Sensoren Endschalter und insbesondere ein Betätigungsschalter in Form einer Lichtschranke oder Kontaktmatte vorgesehen, die bei Betätigung jeweils unterschiedliche Drehzahl bzw. Drehrichtung des Motors auslösen. Die Änderung der Drehzahl erfolgt bei dem dort dargestellten Ausführungsbeispiel durch Zuführung von Gleich-oder Wechselstromanteilen im Sternpunkt eines drei Wicklungen aufweisenden Elektromotors.Such an arrangement is known for example from DE-A 2 405 281. Here, limit switches and in particular an actuation switch in the form of a light barrier or contact mat are provided as sensors, which trigger different speeds or directions of rotation of the motor when actuated. In the exemplary embodiment shown there, the speed is changed by supplying direct or alternating current components in the star point of an electric motor having three windings.

Bei einem solchen automatischen Torantrieb, der unter normalen Verhältnissen gut arbeitet, ergeben sich jedoch Schwierigkeiten, wenn ein starker Winddruck auf dem Tor lastet, so daß dessen Bewegung, je nachdem ob der Wind ihr entgegenwirkt oder sie unterstützt, in unerwünschter Weise zu langsam oder zu schnell erfolgt.In such an automatic door operator, which works well under normal conditions, difficulties arise when a strong wind pressure is on the door, so that its movement, depending on whether the wind counteracts it or supports it, undesirably too slow or too done quickly.

Aufgabe der Erfindung ist es daher, einen Antrieb zu schaffen, mit dem unabhängig von dem auf der Tür oder dem Tor lastenden Winddruck und dem dadurch bewirkten, mehr oder weniger großen, schwankenden Torwiderstand dennoch das Öffnen und Schließen des Tores mit stets gleichbleibender Geschwindigkeit bei allen Bewegungsphasen ausgeführt werden kann.The object of the invention is therefore to provide a drive with which, regardless of the wind pressure on the door or the gate and the resulting, more or less large, fluctuating gate resistance, the opening and closing of the gate with constant speed at all Movement phases can be carried out.

Die Lösung dieser Aufgabe besteht darin, daß mindestens ein als Temperaturfühler ausgebildeter Sensor an einer windgeschützten Stelle und mindestens ein weiterer, ebenfalls als Temperaturfühler ausgebildeter Sensor an einer dem Wind ausgesetzten Stelle im Torbereich vorgesehen ist, und daß der Motor (4, 5, 6) in Abhängigkeit von einem aus der Differenz der Signale der Temperaturfühler gebildeten Signal in seiner Drehzahl regelbar ist.The solution to this problem is that at least one sensor designed as a temperature sensor is provided at a location protected from the wind and at least one further sensor also designed as a temperature sensor is provided at a location in the gate area exposed to the wind, and that the motor (4, 5, 6) its speed can be regulated as a function of a signal formed from the difference between the signals of the temperature sensors.

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 einer Temperaturmessung an einer windgeschützten und an einer dem Wind ausgesetzten Stelle zurückgeführt. An der dem Wind ausgesetzten 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.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 location which is protected from the wind and at a point 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.

Die Erfindung ist in der Zeichnung beispielsweise und schematisch dargestellt. Es zeigen :

  • Figur 1 eine Ansicht eines Schiebetores und
  • Figur 2 eine Motorschaltung.
The invention is shown in the drawing, for example and schematically. Show it :
  • Figure 1 is a view of a sliding gate and
  • Figure 2 shows a motor circuit.

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 in Serienschaltung aus zwei Phasen des Drehstromnetzes gespeist werden, während der dritten Wicklung 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 fed in series from two phases of the three-phase network, during 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.

Bei diesem Ausführungsbeispiel 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.In this exemplary embodiment, the size (including the sign) and / or phase of the voltage or of the current which is fed 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.

Bei der dargestellten Anordnung ist an einer dem Wind ausgesetzten Stelle oberhalb des Tores ein Temperaturfühler 11 vorgesehen, dessen Ausgangssignal ebenso wie das eines weiteren, an einer windgeschützten Stelle angeordneten und daher hier nicht näher dargestellten Temperaturfühlers zu einem der Eingänge 12 der Steuer-und Regeleinrichtung 9 geführt ist. Hierbei besteht die Möglichkeit, weitere temperaturabhängige Sensoren noch an anderen Stellen, beispielsweise an der Schließkante 10 des Tores 1, vorzusehen, falls unterschiedliche Windeinflüsse an den verschiedenen Stellen herrschen. Aus den unterschiedlichen Differenzen der Sensorsignale, die den Eingängen 12 zugeführt werden, werden die Steuerbefehle für die Einstellung der Stromversorgung 7 abgeleitet. Durch Eingabe entsprechender Bewegungsprogramme in die Steuer- und Regeleinrichtung 9 beim Ansprechen verschiedener Sensoren und beim Auftreten verschiedener, auch unterschiedlich großer Sensorsignale wird es möglich, verschiedene, für den jeweiligen Fall gewünschte Bewegungen des Tores 1 zu erzielen.In the arrangement shown, a temperature sensor 11 is provided at a location exposed to the wind above the gate, the output signal of which, like that of a further temperature sensor arranged at a wind-protected location and therefore not shown here, to one of the inputs 12 of the control and regulating device 9 is led. It is possible to provide further temperature-dependent sensors at other points, for example on the closing edge 10 of the gate 1, if there are different wind influences at the different points. The control commands for setting the power supply 7 are derived from the different differences in the sensor signals that are fed to the inputs 12. By entering appropriate movement programs in the control and regulating device 9 when different sensors respond and when different sensor signals of different sizes occur, it is possible to achieve different movements of the gate 1 desired for the respective case.
