Der zweite Motor ist ein Linearantrieb, der die Schiebelager linear mit einer gewissen linearen Geschwindigkeit innerhalb der Türebene antreibt. Die beiden Motoren beaufschlagen das Falttürblatt mit zwei unterschiedlichen Krafteinleitungsvektoren. Der erste Motor beaufschlagt das Falttürblatt mit einem Drehmoment.

Also, the first motor in the region of the closed position and / or the second motor in the region of the open position has a favorable drive torque. In these areas, the control device may be designed to detect an obstacle and / or a blockage of the folding door leaf by the control device measuring and / or evaluating a nominal deviation of the drive speed and / or the current consumption of the respective drive motor which mainly drives the folding door leaf in the area and or comparing the values of the motors against each other.
In einer besonders vorteilhaften Ausführung ist vorgesehen, dass die beiden Antriebsmotoren redundant ausgebildet sind. Bei Ausfall eines der Antriebsmotoren ist der andere Motor bzw. sind die anderen Motoren so ausgebildet, dass die Falttüre noch automatisch angetrieben zum Öffnen bzw. Schließen betätigbar ist.In a particularly advantageous embodiment, it is provided that the two drive motors are designed to be redundant. In case of failure of one of the drive motors of the other motor or the other motors are designed so that the folding door is still driven automatically open or close actuated.

Der Falttürantrieb ist an dem oberen horizontalen Blendrahmen der Falttür angeordnet und weist eine Abdeckung 4 auf. In
Der zweite Antriebsmotor 6 ist im Randbereich des Antriebs angeordnet und treibt über ein zwischengeschaltetes Getriebe 51 die Schiebelager 26, 36 der beiden Falttürblätter 2, 3 an. Die Schiebelager 26, 36 sind linear verschiebbar gelagert und über eine vorzugsweise justierbare Aufhängevorrichtung mit den Falttürblättem 2, 3 verbunden. Das Schiebelager 26 des linken Falttürblatts 2 ist über einen Mitnehmer mit dem einen Trum des umlaufenden Treibriemens 52 verbunden. Entsprechend ist das Schiebelager des rechten Falttürblatts 3 über einen Mitnehmer mit dem anderen Trum des umlaufenden Treibriemens 52 verbunden. So wird der synchron gegenläufige Antrieb der Falttürblatter sichergestellt. Der umlaufende Treibriemen 52 weist zwei im Randbereich des Antriebs angeordnete Umlenkrollen 56 auf und wird von dem Antriebsmotor 6, der mit einer Umlenkrolle antriebsverbunden ist, angetrieben.The
Die Antriebsmotoren sind elektrisch mit einer gemeinsamen Steuerungseinrichtung 7 verbunden. Die Steuerungseinrichtung 7 weist einen Mikroprozessor sowie mehrere Ein- und/oder Ausgänge auf und steuert den Öffnungs- und Schließvorgang des Falttürantriebs, indem sie die Motoren 5, 6 gezielt steuert bzw. regelt. Die Motoren 5, 6 sind jeweils über separate Versorgungsleitungen mit der Steuerungseinrichtung 7 verbunden. Durch das Variieren der Versorgungsspannung auf der Versorgungsleitung des ersten Motors und/oder des zweiten Motors steuert die Steuerungseinrichtung die Drehzahl und somit die Geschwindigkeit jedes einzelnen angeschlossenen Motors. Die Steuerungseinrichtung ist zum Messen der Geschwindigkeit und zum Steuern der Geschwindigkeit eines angeschlossenen Motors über eine einzige zweipolige Verbindungsleitung ausgebildet, indem die Steuerungseinrichtung die Kommutatorschwankungen des Motors auf dieser Verbindungsleitung misst und auswertet. Durch Variation der Versorgungsspannung des Motors erhöht oder erniedrigt die Steuerungseinrichtung die Motordrehzahl entsprechend der Vorgabe.The drive motors are electrically connected to a common control device 7. The control device 7 has a microprocessor and a plurality of inputs and / or outputs and controls the opening and closing operation of the Falttürantriebs by the
Die Geschwindigkeitsvorgabe ergibt sich aus den geometrischen Verhältnissen des Falttürantriebs. In
wobei:
- ω = Winkelgeschwindigkeit der Türwelle
- L= Breite eines Flügels
- x= Position des Schiebelagers
- ν = Geschwindigkeit des Schiebelagers
in which:
- ω = angular velocity of the door shaft
- L = width of a grand piano
- x = position of the sliding bearing
- ν = speed of the sliding bearing
Die Steuerungseinrichtung 7 ist als elektrisches Getriebe ausgebildet, indem sie die Geschwindigkeiten der Motoren entsprechend der obigen Formel in Abhängigkeit der Position der Schiebelager und/oder der Öffnungs bzw. Schließstellung des Falttürblatts stufenlos steuert.The control device 7 is designed as an electric transmission by continuously controlling the speeds of the motors according to the above formula, depending on the position of the slide bearings and / or the opening or closing position of the folding door leaf.
Die Position der Schiebelager 26, 36 bzw. der Falttürblätter 2, 3 ermittelt die Steuerungseinrichtung 7 durch Integration der Geschwindigkeit der Schiebelager und/oder der Türwellen. Diese Wegmessung über Integration der Geschwindigkeit ist aufgrund sich aufaddierender Ungenauigkeiten naturgemäß fehlerbehaftet. Zur Kompensation dieses Fehlers sind Nulllagenschalter als Referenz vorgesehen, die von dem Falttürblatt in Nulllage betätigt werden.The position of the
Die Steuerungseinrichtung 7 ist zum Erkennen eines Hindernisses ausgebildet, indem sie eine, z.B. infolge einer Blockade der Falttür durch ein Hindernis hervorgerufene Abweichung der Geschwindigkeit eines oder mehrerer an die Steuerung angeschlossener Motoren detektiert. Zusätzlich dazu oder alternativ dazu kann die Steuerungseinrichtung 7 zur Hinderniserkennung durch Messen der Stromaufnahme der angeschlossenen Motoren ausgebildet sein. Bei einer infolge einer Blockade der Falttür unzulässig hohen Stromaufnahme eines oder mehrerer angeschlossener Motoren, erkennt die Steuerungseinrichtung ein Hindernis und leitet ein Hindernisprogramm ein, z.B. eine Reversierung des Falttürantriebs.The control device 7 is designed to detect an obstacle by using a, e.g. detected as a result of a blockage of the folding door caused by an obstacle deviation of the speed of one or more connected to the controller motors. In addition or alternatively, the control device 7 may be designed to detect obstacles by measuring the current consumption of the connected motors. In the event of an inadmissibly high current consumption of one or more connected motors due to a blockage of the folding door, the control device recognizes an obstacle and initiates an obstacle program, e.g. a reversal of the folding door drive.
Im Bereich der Offenstellung des Falttürblatts weist der erste Motor 5, infolge der durch die Flügelaufhängung hervorgerufenen Reibung, die im Zusammenspiel mit dem ungünstigen Krafteinleitungswinkel der Türwelle 24 einen sehr großen Widerstand ergibt, ein sehr hohes Antriebsmoment auf. Der zweite Motor 6 weist im Bereich der Offenstellung des Falttürblatts infolge der in diesem Bereich günstigeren Krafteinleitung über die Schiebelager ein sehr viel geringeres Antriebsmoment auf. Im Bereich der Schließstellung kehrt sich das Momentenverhältnis der Antriebsmotoren um. Der erste Motor 5 weist im Bereich der Schließstellung infolge der in diesem Bereich günstigeren Krafteinleitung über die Türwelle 24 ein geringes Antriebsmoment auf, während der zweite Motor im Bereich der Schließstellung aufgrund der linearen, die lineare Antriebsbewegung sperrenden Anordnung des Falttürblatts 2 eine sehr ungünstige Krafteinleitung hat und demzufolge hohen Widerstand überwinden muss.In the area of the open position of the folding door leaf, the
Aufgrund des bei der Öffnungs- bzw. Schließbewegung unterschiedlichen Momentenverlaufs bzw. Geschwindigkeitsverlaufs an den Antriebsmotoren ist im Bereich der Offenstellung der Falttüre der zweite Motor 6, der die Schiebelager antreibt, hauptsächlich als Antriebsmotor und der erste Motor 5 hauptsächlich als Geschwindigkeitssensor ausgebildet. Im Bereich der Schließstellung ist dementsprechend der erste Motor 5, der die Türwellen antreibt, hauptsächlich als Antriebsmotor und der zweite Motor hauptsächlich als Geschwindigkeitssensor ausgebildet. Während der Öffnungs- bzw. Schließbewegung ändert sich das Momenten- und Drehzahlverhältnis der Motoren stufenlos nach Vorgabe der in
Die Steuerungseinrichtung 7 ermittelt diesen Verlauf selbsttätig, indem Sie bei Bedarf, z.B. bei Wartung oder Inbetriebnahme eine Lernfahrt durchführen kann und dabei die entsprechenden Parameter misst und in einem nichtflüchtigen Speicher speichert.The control device 7 determines this course automatically by, if necessary, e.g. During maintenance or commissioning, you can carry out a learning run and measure the corresponding parameters and save them in a non-volatile memory.
In der vorangehenden Beschreibung sowie in den nachfolgende Ansprüchen ist von einem Falttürantrieb die Rede. Selbstverständlich können auch Anordnungen größerer Erstreckung, insbesondere Falttore und Faltwände, erfindungsgemäß ausgeführt werden.In the foregoing description and in the following claims is a folding door drive the speech.
