Description

Die Erfindung betrifft ein Verfahren zum Betrieb einer automatischen Karusselltüranlage nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a method for operating an automatic revolving door system according to the preamble of patent claim 1.

Aus der US 4 530 183 ist eine automatische Karusselltüranlage bekannt, die mittels DC-Motor die Karusselltürflügel antreibt und abbremst. Aus der EP 1 223 290 A2 ist eine Drehtüranlage bekannt, deren Bremse so ausgebildet ist, dass die Bremskräfte nicht auf das Getriebe übergeleitet werden und somit neben einem schnellen und sicheren Abbremsen ein langzeit sicherer Betrieb der gesamten Drehtüranlage ermöglicht wird.From the US 4,530,183 an automatic revolving door system is known, which drives and slows down the revolving door panels by means of a DC motor. From the EP 1 223 290 A2 is known a revolving door system, the brake is designed so that the braking forces are not transferred to the transmission and thus in addition to a fast and safe braking a long-term safe operation of the entire revolving door system is possible.

Aus der DE 42 07 705 C1 ist eine automatische Karusselltüranlage mit mehreren um eine zentrale Drehachse gemeinsam drehbar gelagerten Karusselltürflügeln bekannt. Eine Antriebseinrichtung dient zum Antrieb der Karusselltürflügel. Mittels einer Bremseinrichtung ist die Bewegung der Karusselltürflügel abbremsbar. Eine Steuerungseinrichtung dient zur Ansteuerung der Antriebseinrichtung und der Bremseinrichtung. Dadurch, dass die Bremskraft ohne Abstufungen lediglich einund ausschaltbar ist, ist eine Überprüfung der Bremseinrichtung ohne Behinderung der Drehbewegung der Karusselltürflügel nicht möglich. Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Karusselltüranlage derart weiterzuentwickeln, dass eine Überprüfung der Bremseinrichtung ohne Behinderung der Drehbewegung der Karusselltürflügel möglich ist.From the DE 42 07 705 C1 is an automatic revolving door system with several rotatable about a central axis of rotation rotatably mounted revolving door wings known. A drive device serves to drive the revolving door leaf. By means of a braking device, the movement of the revolving door wing can be braked. A control device serves to control the drive device and the braking device. Due to the fact that the braking force can only be switched on and off without gradations, it is not possible to check the braking device without hindering the rotary movement of the revolving door wings. The invention has for its object to further develop a generic revolving door system such that a review of the braking device without obstructing the rotational movement of the revolving door is possible.

Die Aufgabe wird durch die Merkmale des Verfahrensanspruchs 1 gelöst.The object is solved by the features of method claim 1.

Die Unteransprüche bilden vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung.The subclaims form advantageous embodiments of the invention.

Die Steuerungseinrichtung ist so ausgebildet, dass die Prüfung der Bremseinrichtung während der Drehbewegung der Karusselltürflügel durchführbar ist. Dadurch, dass die Bremseinrichtung eine stufenlos verstellbare Bremskraft aufweist, wird die Drehbewegung der Karusselltürflügel durch die Prüfung der Bremseinrichtung nicht oder zumindest nur unwesentlich behindert, Für den Nutzer ist diese Prüfung der Bremse also gar nicht erkennbar, da der Begehkomfort der Karusselltüranlage nicht eingeschränkt wird.The control device is designed so that the test of the braking device during the rotational movement of the revolving door is feasible. Characterized in that the braking device has a continuously adjustable braking force, the rotational movement of the revolving door is not obstructed by the examination of the braking device or at least only slightly, for the user, this test The brake so not recognizable because the comfort of the revolving door is not limited.

Die Bremseinrichtung kann auf einer Abtriebswelle eines Antriebsmotors der Antriebseinrichtung angeordnet sein. Alternativ ist die Anordnung der Bremseinrichtung auf einer Antriebswelle oder Abtriebswelle eines Getriebes der Antriebseinrichtung oder auf der Drehachse der Karusselltüranlage angeordnet ist.The braking device can be arranged on an output shaft of a drive motor of the drive device. Alternatively, the arrangement of the braking device is arranged on a drive shaft or output shaft of a transmission of the drive device or on the axis of rotation of the revolving door system.

Die Bremseinrichtung ist als Scheibenbremse ausgebildet. Hierzu weist sie eine mit einer Welle der Antriebseinrichtung drehfest verbundene Bremsscheibe auf, welche von einem ortsfest an der Antriebseinrichtung montierten Bremssattel umgriffen wird. die im Bremssattel angeordneten Bremsbacken sind von der Steuerungseinrichtung ansteuerbar, wobei sich Scheibenbremsen prinzipiell sehr gut zur stufenlosen Verstellung der Bremskraft eignen.The braking device is designed as a disc brake. For this purpose, it has a rotatably connected to a shaft of the drive means connected to the brake disc, which is encompassed by a fixedly mounted on the drive device caliper. the arranged in the brake caliper brake shoes are controlled by the controller, disc brakes are in principle very well suited for continuous adjustment of the braking force.

Die mittels der Steuerungseinrichtung durchführbare Prüfung der Bremseinrichtung kann folgende Schritte umfassen: Der Antriebsmotor der Antriebseinrichtung wird zuerst auf eine bestimmte, konstante Geschwindigkeit angesteuert, wobei die Bremseinrichtung noch nicht angesteuert ist, und der Motorstrom des Antriebsmotors für diesen Betriebszustand wird gemessen. Danach wird die Bremseinrichtung auf eine relativ geringe Bremskraft, z.B. 20% der Maximalbremskraft, angesteuert, und es wird der Motorstrom des Antriebsmotors für diesen Betriebszustand gemessen. Die Ansteuerung auf diese Prüfbremskraft kann kontinuierlich in Form einer Rampe oder abgestuft erfolgen.The testing of the braking device which can be carried out by means of the control device can comprise the following steps: The drive motor of the drive device is first driven to a specific, constant speed, the braking device not yet being activated, and the motor current of the drive motor for this operating state is measured. Thereafter, the braking device is set to a relatively low braking force, e.g. 20% of the maximum braking force, driven, and it is measured, the motor current of the drive motor for this operating condition. The control of this test brake force can be carried out continuously in the form of a ramp or stepped.

Die Ansteuerung der Bremseinrichtung mit der relativ geringen Bremskraft bewirkt, dass sich die Drehbewegung der Karusselltürflügel nicht nennenswert verlangsamt. Dagegen steigt der Motorstrom des Antriebsmotors mit zunehmender Bremskraft, welcher er entgegenwirken muss, an. Weist die Bremseinrichtung keine oder zumindest verringerte Bremskraft auf, so unterbleibt dieses Ansteigen des Motorstroms trotz angesteuerter Bremseinrichtung.The control of the braking device with the relatively low braking force causes the rotational movement of the revolving door does not slow significantly. In contrast, the motor current of the drive motor increases with increasing braking force, which he must counteract on. Indicates the braking device no or at least reduced braking force, so this increase of the motor current is omitted despite the controlled braking device.

Der bei angesteuerter Bremseinrichtung gemessene Motorstrom kann mit einem in der Steuerungseinrichtung hinterlegten Referenzwert verglichen werden, woraufhin eine Sicherheitsreaktion ausgelöst wird, falls der gemessene Motorstrom den Referenzwert unterschreitet.The motor current measured when the braking device is activated can be compared with a reference value stored in the control device, whereupon a safety reaction is triggered if the measured motor current falls below the reference value.

Alternativ kann der bei angesteuerter Bremseinrichtung gemessene Motorstrom des Antriebsmotors mit dem zuvor gemessenen Motorstrom verglichen werden. Hierzu wird ein auf dem bei nicht angesteuerter Bremseinrichtung gemessenen Motorstrom basierender Abweichungswert berechnet und danach der bei angesteuerter Bremseinrichtung gemessene Motorstrom des Antriebsmotors mit dem Abweichungswert verglichen, woraufhin eine Sicherheitsreaktion ausgelöst wird, falls der bei angesteuerter Bremseinrichtung gemessene Motorstrom den Abweichungswert unterschreitet. Durch diesen Vergleich mit dem zuvor gemessenen Motorstrom können somit auch "schleichende", im Normalbetrieb auftretende Veränderungen des Motorstroms, welche durch Verschleiß oder Verschmutzung von Komponenten der Karusselltüranlage verursacht werden können, berücksichtigt werden.Alternatively, the motor current of the drive motor measured when the braking device is activated can be compared with the previously measured motor current. For this purpose, a deviation value based on the motor current measured on the non-activated braking device is calculated and then the motor current of the drive motor measured with the braking device controlled is compared with the deviation value, whereupon a safety reaction is triggered if the motor current measured in the case of the controlled braking device falls below the deviation value. By this comparison with the previously measured motor current thus "creeping" occurring in normal operation changes in the motor current, which can be caused by wear or contamination of components of the revolving door system, can be considered.

Die genannten Über- bzw. Unterschreitungen der Abweichungswerte bedeuten, dass die Bremseinrichtung keine oder zumindest verminderte Bremskraft hat.The said overshoots or undershoots of the deviation values mean that the braking device has no or at least reduced braking force.

Die Sicherheitsreaktion kann, um den Weiterbetrieb der Karusselltüranlage zu gewährleisten, eine Verringerung der Drehgeschwindigkeit der Karusselltürflügel umfassen, um sicherzustellen, dass die nur noch mit verringerter Bremskraft funktionierende Bremseinrichtung die Karusselltürflügel im Bedarfsfall rechtzeitig zum Stillstand bringen kann.The safety response, to ensure continued operation of the revolving door system, may include reducing the speed of rotation of the revolving door panels to ensure that the braking device, which only operates with reduced braking power, can stop the revolving door panels in a timely manner when needed.

Die Sicherheitsreaktion kann jedoch, insbesondere bei zu geringer oder ganz fehlender Bremskraft, auch eine sofortige Stillsetzung des Antriebsmotors, ggf. in Verbindung mit vollständiger Ansteuerung der Bremseinrichtung, d.h. höchstmöglicher Bremskraft, umfassen.However, the safety reaction can, especially if the braking force is too small or completely absent, also include an immediate stopping of the drive motor, possibly in conjunction with complete control of the braking device, ie the highest possible braking force.

Ferner kann eine optische und/oder akustische Anzeigeeinrichtung vorgesehen sein, mittels welcher der Zustand fehlender oder zumindest verringerter Bremskraft der Bremseinrichtung anzeigbar ist. Über einen drahtgebundenen oder drahtlose Schnittstelle der Steuerungseinrichtung kann dieser Zustand auch an entfernte Einrichtungen, z.B. eine Gebäudeleitzentrale oder einen Servicepartner übermittelt werden.Furthermore, an optical and / or acoustic display device can be provided, by means of which the state of missing or at least reduced braking force of the braking device can be displayed. Through a wired or wireless interface of the controller, this condition may also be transmitted to remote devices, e.g. a building control center or a service partner are transmitted.

Die Abtriebswelle 14 des Getriebes 12, welches in diesem Ausführungsbeispiel als Winkelgetriebe ausgebildet ist, ist koaxial mit der Drehachse 3 der Mittelsäule 4 angeordnet und drehfest mit dieser verbunden. Der Antriebsmotor 9 der Antriebseinrichtung 8 ist mittels einer in dem Aufnahmeraum 6 angeordneten Steuerungseinrichtung 15 über nicht dargestellte, elektrische Signalleitungen ansteuerbar, beispielsweise ausgelöst durch die Betätigung eines nicht dargestellten Programmschalters und/oder durch das Signal eines nicht dargestellten Ansteuersensors.The sectional view of the Fig. 2 schematically shows the drive means 8 of the revolving door system 1. In the area of the rotation axis 3 of the revolving door 2, a bearing 7 are arranged in the receiving space 6 and in the ground, by means of which the center column 4 is rotatably mounted with the connected revolving door 2 wings. To drive the center column 4 with the connected revolving door panels 2, a drive device 8 is arranged in the receiving space 6 of the ceiling construction, which comprises an electric drive motor 9. The output shaft 10 of the drive motor 9 is rotatably connected to the drive shaft 13 of a transmission 12. The output shaft 14 of the transmission 12, which is formed in this embodiment as an angle gear, is arranged coaxially with the axis of rotation 3 of the center column 4 and rotatably connected thereto. The drive motor 9 of the drive device 8 is controlled by means of a arranged in the receiving space 6 control device 15, not shown, electrical signal lines, for example triggered by the operation of a program switch, not shown, and / or by the signal of a drive sensor, not shown.

Zur Abbremsung oder Blockierung der Drehbewegung der Karusselltürflügel 2 ist in dem Aufnahmeraum 6 eine Bremseinrichtung 16 angeordnet, welche mittels der Steuerungseinrichtung 15 über nicht dargestellte, elektrische Signalleitungen ansteuerbar ist. Die Ansteuerung der Bremseinrichtung 16 kann beispielsweise durch das Signal eines nicht dargestellten Sicherheitssensors und/oder durch die Betätigung eines nicht dargestellten Programmschalters erfolgen.To decelerate or block the rotational movement of the revolving door 2, a braking device 16 is arranged in the receiving space 6, which is controlled by the control device 15 via not shown, electrical signal lines. The control of the braking device 16 can be done for example by the signal of a safety sensor, not shown, and / or by the operation of a program switch, not shown.

Die Bremseinrichtung 16 ist als Scheibenbremse mit einem Bremssattel 17, in welchem Bremsbacken angeordnet sind, und einer rotierenden Bremsscheibe 18 ausgebildet, wobei die Bremsscheibe 18 drehfest auf der Abtriebswelle 10 des Antriebsmotors 9 angeordnet ist. In dem Ausführungsbeispiel gemäß Fig. 3 ist die Bremsscheibe 18 der Bremseinrichtung 16, von dem vorausgehenden Ausführungsbeispiel abweichend, drehfest auf einer Abtriebswelle 14 des Getriebes 12 angeordnet.The brake device 16 is designed as a disc brake with a brake caliper 17, in which brake shoes are arranged, and a rotating brake disc 18, wherein the brake disc 18 is arranged rotationally fixed on the output shaft 10 of the drive motor 9. In the embodiment according to Fig. 3 is the brake disc 18 of the brake device 16, deviating from the preceding embodiment, rotatably disposed on an output shaft 14 of the transmission 12.

Die Steuerungseinrichtung 15 ist so ausgebildet, dass die Prüfung der Bremseinrichtung 16 während der Drehbewegung der Karusselltürflügel 2 durchführbar ist. Dadurch, dass die Bremseinrichtung 16 eine stufenlos verstellbare Bremskraft aufweist, wird die Drehbewegung der Karusselltürflügel 2 durch die Prüfung der Bremseinrichtung 16 nicht oder zumindest nur unwesentlich behindert, denn die Ansteuerung der Bremseinrichtung 16 mit einer relativ geringen Bremskraft bewirkt, dass sich die Drehbewegung der Karusselltürflügel 2 nicht nennenswert verlangsamt. Dagegen steigt der Motorstrom des Antriebsmotors 9 mit zunehmender Bremskraft, welcher er entgegenwirken muss, an.The control device 15 is designed so that the test of the braking device 16 during the rotational movement of the revolving door 2 is feasible. Characterized in that the braking device 16 has a continuously adjustable braking force, the rotational movement of the revolving door 2 is not obstructed by the examination of the braking device 16 or at least only slightly, because the activation of the braking device 16 with a relatively low braking force causes the rotational movement of the revolving door 2 does not slow significantly. In contrast, the motor current of the drive motor 9 increases with increasing braking force, which he must counteract on.

Die Prüfung der Bremseinrichtung 16 ist in den Fig. 4 und 5 dargestellt und kann folgende Schritte umfassen:

  • Der Antriebsmotor 9 der Antriebseinrichtung 8 wird zuerst auf eine bestimmte, konstante Geschwindigkeit angesteuert, wobei die Bremseinrichtung 16 noch nicht angesteuert ist, und der Motorstrom IM des Antriebsmotors für diesen Betriebszustand wird gemessen. Danach wird die Bremseinrichtung zum Bremszeitpunkt tB auf eine relativ geringe Bremskraft, z.B. 20% der Maximalbremskraft, angesteuert, und es wird der Motorstrom IM des Antriebsmotors 9 auch für diesen Betriebszustand gemessen. Alternativ zu der dargestellten stufenförmigen Erhöhung der Bremskraft kann diese auch kontinuierlich erhöht werden.
The test of the braking device 16 is in the 4 and 5 and may include the following steps:
  • The drive motor 9 of the drive device 8 is first driven to a specific, constant speed, the brake device 16 is not yet driven, and the motor current I M of the drive motor for this operating state is measured. Thereafter, the braking device at the braking time t B to a relatively low braking force, for example, 20% of the maximum braking force, driven, and it is the motor current I M of the drive motor 9 is also measured for this operating condition. As an alternative to the illustrated stepwise increase in the braking force, this can also be increased continuously.

Zur Auswertung wird der bei angesteuerter Bremseinrichtung 16 gemessene Motorstrom Iist mit einem in der Steuerungseinrichtung hinterlegten Referenzwert IR verglichen. In der Darstellung gemäß Fig. 4a überschreitet der gemessene Motorstrom Iist ab dem Bremszeitpunkt tB den Referenzwert IR deutlich, was durch die Bremskraft der angesteuerten Bremseinrichtung 16 bewirkt wurde; die Bremseinrichtung 16 ist bei diesem Beispiel also funktionsfähig. Dagegen steigt der gemessene Motorstrom Iist in der Darstellung gemäß Fig. 4b ab dem Bremszeitpunkt tB nur langsam an und erreicht den Referenzwert IR nicht; die Bremseinrichtung 16 ist bei diesem Beispiel also nur bedingt funktionsfähig, da sie nicht die volle Bremskraft bewirkt, was beispielsweise durch Verschleiß der Bremseinrichtung 16 bewirkt werden kann.For evaluation, the motor current I measured with controlled braking device 16 is compared with a reference value I R stored in the control device. In the illustration according to Fig. 4a exceeds the measured motor current I is from the braking time t B the reference value I R clearly, which was caused by the braking force of the driven braking device 16; the braking device 16 is therefore functional in this example. In contrast, the measured motor current I is rising in the illustration according to Fig. 4b from the braking time t B only slowly and does not reach the reference value I R ; the braking device 16 is therefore only partially functional in this example, since it does not cause the full braking force, which can be effected for example by wear of the brake device 16.

In der Darstellung gemäß Fig. 5 wird zur Auswertung ein abweichendes Verfahren verwendet: Der bei angesteuerter Bremseinrichtung 16 gemessene Motorstrom Iist des Antriebsmotors 9 wird mit dem zuvor, d.h. ohne Wirkung der Bremseinrichtung 16 gemessenen Motorstrom I0 verglichen. Hierzu wird ein auf dem bei nicht angesteuerter Bremseinrichtung 16 gemessenen Motorstrom I0 basierender Abweichungswert ΔI berechnet und danach der bei angesteuerter Bremseinrichtung 16 gemessene Motorstrom Iist des Antriebsmotors 9 mit dem Abweichungswert ΔI verglichen. In der Darstellung gemäß Fig. 5a überschreitet der gemessene Motorstrom Iist ab dem Bremszeitpunkt tB den Abweichungswert ΔI deutlich, was durch die Bremskraft der angesteuerten Bremseinrichtung 16 bewirkt wurde; die Bremseinrichtung 16 ist bei diesem Beispiel also funktionsfähig. Dagegen steigt der gemessene Motorstrom Iist in der Darstellung gemäß Fig. 5b ab dem Bremszeitpunkt tB nicht an und überschreitet somit den Abweichungswert ΔI nicht; die Bremseinrichtung 16 ist bei diesem Beispiel also nichtfunktionsfähig.In the illustration according to Fig. 5 For example, a different method is used for the evaluation: The motor current I measured when the braking device 16 is driven, of the drive motor 9, is compared with the motor current I 0 previously measured, ie without the action of the braking device 16. For this purpose, a deviation value ΔI based on the motor current I 0 measured when the braking device 16 is not controlled is calculated, and then the motor current I ist of the drive motor 9 measured with the braking device 16 activated is compared with the deviation value ΔI. In the illustration according to Fig. 5a exceeds the measured motor current I t is the offset value B .DELTA.I significantly from the time of braking, which was caused by the braking force of the controlled braking device 16; the braking device 16 is therefore functional in this example. In contrast, the measured motor current I is rising in the illustration according to Fig. 5b from the braking time point t B and thus does not exceed the deviation value ΔI; the braking device 16 is therefore inoperative in this example.

Die Steuerungseinrichtung 15 leitet bei nicht oder nur bedingt funktionsfähiger Bremseinrichtung 16 eine Sicherheitsreaktion, beispielsweise eine Verlangsamung der Drehbewegung der Karusselltürflügel 2 oder eine Stillsetzung der Karusselltüranlage 1 ein.The control device 15 initiates a safety reaction, for example a slowing down of the rotational movement of the revolving door wings 2 or a shutdown of the revolving door system 1, if the braking device 16 is not functional or only partially functional.
