Description

Die Erfindung betrifft einen Falttürantrieb für eine Falttüranlage mit den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a folding door drive for a folding door system having the features of the preamble of patent claim 1.

In der WO 92 /13 300 A1 wird ein elektrischer Türantrieb beschrieben, welcher unter Anderem auch zum Antrieb einer Falttüranlage verwendbar ist. Falttüranlagen weisen in der Regel mindestens ein um eine ortsfeste Türachse drehbar gelagertes Falttürblatt mit einem ersten Flügel und einem zweiten Flügel, die unmittelbar oder über einen oder mehrere gelenkig miteinander verbundene Flügel gelenkig miteinander verbunden sind, auf, wobei ein erster Flügel eine mit der ortsfesten Türachse koaxiale Türwelle aufweist und ein zweiter Flügel mindestens ein Schiebelager aufweist, das in der Türebene horizontal verschiebbar ist. Der Antrieb weist mindestens zwei elektrische Motoren auf.In the WO 92/13300 A1 an electric door drive is described, which among other things also for driving a folding door system is usable. Falttüranlagen usually have at least one rotatable about a fixed door axis stored folding door leaf with a first wing and a second wing, which are connected directly or via one or more hingedly interconnected wings articulated to each other, wherein a first wing with the stationary Türachse Has coaxial door shaft and a second wing has at least one sliding bearing, which is horizontally displaceable in the door plane. The drive has at least two electric motors.

Die EP 0 947 658 A2 beschreibt einen weiteren, mehrmotorigen Antrieb einer Schiebetüranlage, welcher sich prinzipiell auch zum Antrieb einer Falttüranlage eignet.The EP 0 947 658 A2 describes a further, multi-motor drive a sliding door system, which is in principle also suitable for driving a folding door system.

In der DE 91 05 187 U1 wird ein weiterer, jedoch nur einmotoriger Falttürantrieb beschreiben.In the DE 91 05 187 U1 will describe another, but only single-motor folding door drive.

Den Gegenständen aller drei genannten Druckschriften ist gemeinsam, dass die Motoren jeweils linear verschiebbare Schiebelager, die an den Enden der Hauptschließkanten der Falttürblätter angeordnet sind, antreiben. Bei vollständig geschlossener Tür ist eine Kraftkomponente in Richtung senkrecht zur Türebene erforderlich. Beim Ausführungsbeispiel der DE 91 05 187 U1 wird diese Kraft komponente durch eine Vorrichtung mit Ausstellhebel, der eine Rolle aufweist, eingeleitet. Der Ausstellhebel beaufschlagt das Falttürblatt in Schließstellung senkrecht zur Türebene. Nachteilig bei dieser Lösung ist die aufwendige mechanische Konstruktion und die Gefahr des Verklemmens der Tür in Schließstellung.The objects of all three mentioned publications have in common that the motors respectively linearly displaceable sliding bearings, which are arranged at the ends of the main closing edges of the folding door leaves, drive. When the door is completely closed, a force component in the direction perpendicular to the door level is required. In the embodiment of DE 91 05 187 U1 this force component by a device with release lever, which has a role initiated. The opening lever acts on the folding door leaf in the closed position perpendicular to the door level. A disadvantage of this solution is the complex mechanical construction and the risk of jamming the door in the closed position.

Die DE 44 43 500 A1 beschreibt eine Falttüranlage mit zwei gegenläufigen Falttürblättern, bei welcher die ortsfesten Drehachsen der Falttürblätter angetrieben werden. Ein Antriebsmotor treibt die beiden ortsfesten Drehachsen der Falttürblätter gegenläufig an. Nachteilig ist, dass in Offenstellung der Tür das erforderliche Antriebsmoment sehr hoch ist und stark von den Reibungsverhältnissen der Flügelaufhängung abhängt. Die Gefahr des Verklemmens der Flügel in Offenstellung ist hier sehr groß. Nachteilig ist auch die aufwendige Regelung, da das erforderliche Antriebsmoment sehr stark von dem Drehwinkel der Drehachse der Falttürblätter abhängt und eine Behinderungserkennung beim Offnen bzw. Schließen der Falttür sehr erschwert ist.The DE 44 43 500 A1 describes a folding door system with two opposing folding door leaves, in which the fixed axes of rotation of the folding door leaves are driven. A drive motor drives the two stationary axes of rotation of the folding door leaves in opposite directions. The disadvantage is that in the open position of the door, the required drive torque is very high and strongly depends on the friction conditions of the wing suspension. The risk of jamming the wings in the open position is very large here. Another disadvantage is the complex control, since the required drive torque depends very much on the rotation angle of the axis of rotation of the folding door leaves and a disability detection when opening or closing the folding door is very difficult.

In der US 5,711,112 wird ein weiterer, zweimotoriger Antrieb einer Schiebetüranlage beschrieben, dessen Motoren jeweils linear verschiebbare Schiebelager, die an den Enden der Hauptschließkanten der Schlebetürblätter angeordnet sind, antreiben.In the US 5,711,112 another, twin-motor drive a sliding door system is described, the motors each linearly sliding sliding bearings, which are arranged at the ends of the main closing edges of the Schleucherürblätter drive.

Aufgabe der Erfindung ist es, einen Falttürantrieb zu entwickeln, der einfach aufgebaut ist und eine hohe Betriebssicherheit aufweist.The object of the invention is to develop a folding door drive, which is simple and has a high reliability.

Erfindungsgemäß wird die Aufgabe mit dem Gegenstand des Patentanspruchs 1 gelöst.According to the invention the object is achieved with the subject of claim 1.

Der erste Motor ist zum Antrieb der Türwelle ausgebildet, indem er direkt oder über ein zwischengeschaltetes Getriebe mit der Türwelle drehfest verbunden ist. Der zweite Motor ist zum Antrieb des Schiebelagers ausgebildet, indem er über ein zwischengeschaltetes Getriebe mit dem Schiebelager verbunden ist und das zwischengeschaltete Getriebe zum Umsetzen der rotierenden Antriebsbewegung des zweiten Motors in eine lineare Antriebsbewegung des Schiebelagers ausgebildet ist.The first motor is designed to drive the door shaft by being connected to the door shaft rotatably directly or via an intermediate gearbox. The second motor is designed to drive the sliding bearing by being connected via an intermediate gear to the sliding bearing and the intermediate gear for converting the rotary drive movement of the second motor is formed in a linear drive movement of the sliding bearing.

Der erste Motor ist ein elektrischer Rotationsantrieb mit Gleichstrom- oder Wechselstrornbetrieb, der die Türwelle mit einer gewissen Winkelgeschwindigkeit antreibt. 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. Der zweite Motor beaufschlagt das Falttürblatt mit einem linearen Kraftvektor. Die unterschiedliche Krafteinleitung der Antriebsmotoren ist so ausgebildet, dass der erste Motor in dem Bereich, in dem die Krafteinleitung des zweiten Motors ungünstig ist eine günstige Krafteinleitung aufweist und umgekehrt.The first motor is a DC or AC electric rotary actuator that drives the door shaft at a certain angular velocity. The second motor is a linear actuator that drives the sliding bearings linearly with a certain linear velocity within the door plane. The two motors act on the folding door leaf with two different force introduction vectors. The first motor acts on the folding door leaf with a torque. The second motor acts on the folding door leaf with a linear force vector. The different introduction of force of the drive motors is designed so that the first motor in the region in which the introduction of force of the second motor is unfavorable has a favorable introduction of force and vice versa.

Der zweite Motor ist als herkömmlicher elektrischer Rotationsmotor mit Gleichstrom- oder Wechselstrombetrieb ausgebildet.

The door shaft 24 is fixedly connected to the folding door leaf 2 and rotatably mounted in a stationary door pivot bearing. The door pivot bearing consists of an upper and a lower pivot bearing. The folding door leaf 2 is pivotally mounted on the door shaft 24. In a corresponding manner, the right folding door leaf 3 is pivotally mounted on a door shaft 34. At their front closing edge, the wings 22, 31 are suspended by means of a suspension device 25, 35 on slidably mounted sliding bearings. The sliding bearings are arranged in the upper horizontal frame spar and formed linearly displaceable.

Der Falttürantrieb ist an dem oberen horizontalen Blendrahmen der Falttür angeordnet und weist eine Abdeckung 4 auf. In Figur 2 ist die obere Draufsicht des Falttürantriebs schematisch dargestellt. Der Falttürantrieb 1 weist zwei elektrische Antriebsmotoren 5, 6 auf. Der erste Antriebsmotor 5 ist im mittleren Bereich des Antriebs angeordnet und mit beiden Türwellen der gegenläufigen Falttürblätter 2, 3 über eine zwischengeschaltete Getriebevorrichtung 61 drehfest verbunden. Die Getriebevorrichtung 61 weist zwei gegenläufig miteinander kämmende Zahnräder 63a, 63b auf, die Ihrerseits mit je einem umlaufenden Treibriemen 64a, 64b verbunden sind. Die umlaufenden Treibriemen 64a, 64b werden einerseits von den Zahnrädern 63a, 63b angetrieben und treiben andererseits an den oberen Enden der senkrechten Türwellen angeordnete, mit den Türwellen drehfest verbundene Umlenkrollen 55, 65 an. Die Zahnräder 63a, 63b treiben die umlaufenden Treibriemen 64a, 64b gegenläufig an. Durch diese gegenläufige Bewegung der Treibriemen 64a, 64b werden die Falttürblätter synchron gegenläufig im Öffnungssinn bzw. im Schließsinn betätigt.The folding door drive is arranged on the upper horizontal frame of the folding door and has a cover 4. In FIG. 2 the upper plan view of the Falttürantriebs is shown schematically. The folding door drive 1 has two electric drive motors 5, 6. The first drive motor 5 is arranged in the central region of the drive and rotatably connected with two door shafts of the opposite folding door leaves 2, 3 via an intermediate gear device 61. The gear device 61 has two counter-meshing gears 63a, 63b, which in turn are each connected to a circulating drive belt 64a, 64b. The circulating drive belts 64a, 64b are driven on the one hand by the gears 63a, 63b and drive on the other hand at the upper ends of the vertical door shafts arranged, with the door shafts rotatably connected pulleys 55, 65 at. The gears 63a, 63b drive the circulating drive belts 64a, 64b in opposite directions. By this opposite movement of the drive belt 64a, 64b, the folding door leaves are synchronously operated in opposite directions in the opening direction or in the closing direction.

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 second drive motor 6 is arranged in the edge region of the drive and drives via an intermediate gear 51, the sliding bearings 26, 36 of the two Fold door leaves 2, 3 on. The sliding bearings 26, 36 are mounted linearly displaceable and connected via a preferably adjustable suspension device with the Falttürblättem 2, 3. The sliding bearing 26 of the left folding door leaf 2 is connected via a driver with the one run of the circulating drive belt 52. Accordingly, the sliding bearing of the right folding door leaf 3 is connected via a driver with the other run of the circulating drive belt 52. This ensures the synchronous counter-rotating drive of the folding door leaves. The circulating drive belt 52 has two deflection rollers 56 arranged in the edge region of the drive and is driven by the drive motor 6, which is drive-connected to a deflection roller.

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 motors 5, 6 selectively controls or regulates. The motors 5, 6 are each connected to the control device 7 via separate supply lines. By varying the supply voltage on the supply line of the first motor and / or the second motor, the control device controls the speed and thus the speed of each individual connected motor. The control device is designed to measure the speed and to control the speed of a connected motor via a single two-pole connecting line by the control device measuring and evaluating the commutator fluctuations of the motor on this connecting line. By varying the supply voltage of the engine, the control device increases or decreases the engine speed in accordance with the specification.

Die Geschwindigkeitsvorgabe ergibt sich aus den geometrischen Verhältnissen des Falttürantriebs. In Figur 3 ist der geometrische Aufbau dargestellt. Der erste Motor treibt die Türwelle an und der zweite Motor die Schiebelager bzw. die Rollenwagen. Mit den in Figur 3 gewählten Bezeichnungen ergibt sich folgender mathematischer Zusammenhang zwischen der Winkelgeschwindigkeit der Türwellen und der linearen Geschwindigkeit der Schiebelager: ω = 1 4 L 2 - x 2 v

Figure imgb0001

wobei:

  • ω = Winkelgeschwindigkeit der Türwelle
  • L= Breite eines Flügels
  • x= Position des Schiebelagers
  • ν = Geschwindigkeit des Schiebelagers
The speed specification results from the geometric conditions of the folding door drive. In FIG. 3 the geometric structure is shown. The first motor drives the door shaft and the second motor the sliding bearing or the roller carriage. With the in FIG. 3 The following mathematical relationship between the angular velocity of the door shafts and the linear velocity of the sliding bearing results: ω = 1 4 L 2 - x 2 v
Figure imgb0001

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 slide bearings 26, 36 or the folding door leaves 2, 3 determines the control device 7 by integrating the speed of the slide bearings and / or the door shafts. This path measurement via integration of the speed is naturally flawed due to aufaddierender inaccuracies. To compensate for this error zero position switches are provided as a reference, which are actuated by the folding door leaf in zero position.

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 first motor 5, due to the friction caused by the wing suspension, which in conjunction with the unfavorable force introduction angle of the door shaft 24 results in a very high resistance, has a very high drive torque. The second motor 6 has in Area of the open position of the folding door leaf as a result of the more favorable in this area force via the sliding bearings on a much lower drive torque. In the closed position, the torque ratio of the drive motors is reversed. The first motor 5 has in the region of the closed position due to the lower in this area force application via the door shaft 24, a low drive torque, while the second motor in the closed position due to the linear, the linear drive movement blocking arrangement of the Falttürblatts 2 has a very unfavorable force and consequently must overcome high resistance.

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 Figur 3 beschriebenen geometrischen Verhältnissen der Falttüranlage.Because of the different torque progression or speed profile on the drive motors during the opening or closing movement, the second motor 6, which drives the sliding bearings, is designed mainly as a drive motor and the first motor 5 mainly as a speed sensor in the region of the open position of the folding door. In the closed position, accordingly, the first motor 5, which drives the door shafts, is mainly designed as a drive motor and the second motor mainly as a speed sensor. During the opening or closing movement, the torque and speed ratio of the motors changes continuously according to the specification in FIG. 3 described geometric relationships of the folding door system.

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. Of course, arrangements of greater extent, in particular folding doors and folding walls, are carried out according to the invention.
