Description

Die vorliegende Erfindung befasst sich mit einer Sonnenschutzanlage mit einem verstellbaren Behang mit einem Primärantrieb und einem Sekundärantrieb sowie Steuermitteln, die den aktivierten Motor wenigstens in einer eingefahrenen Endstellung des Behangs abschalten.The present invention relates to a sunshade system with an adjustable curtain with a prime mover and a secondary drive and control means that switch off the activated motor at least in a retracted end position of the curtain.

Sonnenschutzanlagen mit zwei Antrieben werden vor allem dort eingesetzt, wo es im Notfall wichtig sein kann, eine verschattete Fenster- oder Türöffnung schnell freizugeben, um beispielsweise einen Fluchtweg zu ermöglichen. Derartige Sonnenschutzanlagen sind beispielsweise aus der DE 200 05 567 U1 oder auch der DE 10 2008 030 483 A1 bekannt, wobei entsprechend der Sekundärantrieb dafür ausgelegt ist, den Behang auf besonders rasche Weise raffen zu können.Sun protection systems with two drives are mainly used where it may be important in an emergency to quickly release a shaded window or door opening, for example, to enable an escape route. Such sun protection systems are for example from the DE 200 05 567 U1 or even the DE 10 2008 030 483 A1 known, in accordance with the secondary drive is designed to be able to gather the curtain in a particularly rapid manner.

Problematisch ist, dass nicht nur der Primärantrieb zum Bewerkstelligen des Verstellen des Behangs im normalen Betrieb sondern auch der Sekundärantrieb über eine zuverlässige Abschaltung wenigstens in der eingefahrenen Endlage verfügen muss, damit der Behang nach einer Notraffung unbeschädigt bleibt und weiterverwendet werden kann. Üblich sind dabei Lösungen, bei denen beide Antriebe jeweils eine eigene Endlageneinheit oder einen eigenen Messwertgeber aufweisen, um die Abschaltpunkte jedes Antriebes zuverlässig zu erfassen und den Antrieb in der richtigen Position abschalten zu können.The problem is that not only the prime mover to make the adjustment of the blind in normal operation but also the secondary drive must have a reliable shutdown at least in the retracted end position so that the curtain remains undamaged after a NENNIFRUNG and can be reused. Common are solutions in which both drives each have their own Endlageneinheit or a separate transmitter to reliably detect the shutdown of each drive and disable the drive in the correct position can.

Hierbei ist problematisch, dass je nach eingesetztem Antrieb technisch bedingt keine Messwertgeber oder auch keine Endlageneinheiten eingesetzt werden können, so dass ein entsprechend hoher Aufwand vorzusehen ist. Es sind auch bereits Lösungen bekannt, bei denen die Abschaltung über eine Drehmomentabschaltung ein einzelner mechanischer Endschalter die sichere Abschaltung beider Antriebe bewerkstelligt, wobei beispielsweise der eingefahrene Behang beim Erreichen seiner Endlage diesen Schalter mechanisch betätigt. Nachteilig bei dieser Lösung ist, dass ein sehr hoher Schaltungsaufwand zu betreiben ist, um beispielsweise dann die Motoren sicher abschalten zu können, wenn völlig unterschiedliche Antriebskonzepte zum Einsatz kommen, beispielsweise ein Wechselstrommotor als Primärantrieb und ein Gleichstrommotor für die Notraffung. Letzteres ist ein durchaus üblicher Fall, da man bestrebt ist, auch die Stromversorgung des Sekundärmotors unabhängig zu gestalten und beispielsweise ein Akkumulator vorgesehen ist, der die Stromversorgung des Sekundärmotors übernimmt.In this case, it is problematic that, depending on the drive used, no transmitters or no end position units can be used for technical reasons, so that a correspondingly high outlay must be provided. There are already known solutions in which the shutdown via a torque shutdown a single mechanical limit switch safe shutdown accomplished both drives, for example, the retracted blinds mechanically actuated when reaching its end position this switch. A disadvantage of this solution is that a very high circuit complexity is to operate, for example, then safely shut off the engines can, if completely different drive concepts are used, for example, an AC motor as a prime mover and a DC motor for emergency recovery. The latter is a very common case, since one endeavors to make the power supply of the secondary motor independently and, for example, an accumulator is provided which takes over the power supply of the secondary motor.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Sonnenschutzanlage zu schaffen, die eine sichere Abschaltung beider Antriebe bei vertretbarem Aufwand ermöglicht.The object of the present invention is to provide a sunshade system that allows safe shutdown of both drives with reasonable effort.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Steuermittel einen gemeinsamen Messwertaufnehmer zur Erfassung der Lageänderung des Behanges und eine Auswerteinheit aufweisen, die die absolute Behangstellung unabhängig von dem aktivierten Motor ermittelt und wenigstens in der eingefahrenen Endstellung die Motorsteuerung wenigstens des aktivierten Sekundärantriebes abschaltet.According to the invention the object is achieved in that the control means have a common transducer for detecting the change in position of the curtain and an evaluation, which determines the absolute Behangstellung independent of the activated motor and at least in the retracted end position, the engine control at least the activated secondary drive off.

Durch die erfindungsgemäße Lösung der Schaffung einer der Motorsteuerung übergeordneten Auswerteinheit können beide Motorsteuerungen auf die ermittelten Daten zurückgreifen. Der Messwertgeber kann bei dieser Lösung unabhängig von den Antrieben an jeder Stelle der Anlage montiert sein, an welcher ein bei der Verstellung des Behangs bewegtes Teil vorgesehen ist. Die in der Regel berührungslos arbeitenden Messwertgeber sind wartungsfrei und unterliegen keinem mechanischen Verschleiß, wie dies beispielsweise bei mechanischen Endschaltern der Fall ist. Die erfasste Iststellung des Behanges erfolgt völlig unabhängig von der Aktivierung des Sekundärantriebes, was z. B. dann wichtig ist, wenn die Notraffung aus einer teilweise ausgefahrenen Stellung erfolgt.As a result of the inventive solution of providing an evaluation unit which is the parent of the engine control unit, both engine control units can resort to the determined data. The transmitter can be mounted in this solution, regardless of the drives at each point of the system on which a moving in the adjustment of the blind part is provided. The normally non-contact transducers are maintenance-free and subject to no mechanical wear, as is the case, for example, with mechanical limit switches. The detected actual position of the curtain is completely independent of the activation of the secondary drive, which z. B. is important when the emergency raking takes place from a partially extended position.

Durch die Ermittlung der Absolutstellung des Behangs bietet die erfindungsgemäße Lösung in einer Weiterbildung den Vorteil, dass die Auswerteinheit den Verstellbereich zwischen einer eingefahrenen und der ausgefahrenen Endlage des Behangs begrenzen kann, ohne dass hierzu ein Mehraufwand an Teilen erforderlich wäre.By determining the absolute position of the curtain, the solution according to the invention offers the advantage, in a further development, that the evaluation unit can limit the adjustment range between a retracted and extended end position of the curtain, without the additional expenditure of parts being required for this purpose.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass die Auswerteinheit eine Bremsposition kurz vor Erreichen einer Endlage des Behanges ermittelt und den aktivierten Motor verlangsamt oder abbremst.In a further preferred embodiment of the invention, it is provided that the evaluation unit determines a braking position shortly before reaching an end position of the curtain and slows down or decelerates the activated motor.

Eine derartige Funktion ist insbesondere bei einer Notraffung von Vorteil, weil dort der Behang auf eine hohe Geschwindigkeit beschleunigt wird und im Falle einer Abschaltung erst in der Endlage die hohe kinetische Energie der Behangteile beim Erreichen eines mechanischen Anschlages Teile des Behanges beschädigen oder zerstören kann. Die Bremsposition kann beispielsweise so gewählt werden, dass im Falle einer Notraffung der Fluchtweg schon frei ist, wobei insbesondere beim aktiven Erzeugen eines Bremsmomentes in dem Sekundärmotor oder auch in dem Primärmotor die Behanggeschwindigkeit gezielt verlangsamt werden kann. Die Motorsteuerung des Primärmotors und/oder des Sekundärmotors kann mit der Auswerteinheit vernetzt sein, um weitergehende Steueroptionen zu erreichen, grundsätzlich ist es aber auch möglich, lediglich die Standardsteuerungen der Motoren durch das Signal der Auswerteinheit zu beeinflussen.Such a function is particularly advantageous in emergency roping, because there the curtain is accelerated to a high speed and in the event of a shutdown only in the end position, the high kinetic energy of Behangteile damage or destroy parts of the curtain when reaching a mechanical stop. The braking position can be selected, for example, so that in the case of a emergency raid the escape route is already free, which can be specifically slowed down especially when actively generating a braking torque in the secondary motor or in the primary motor. The engine control of the primary engine and / or the secondary engine can be networked with the evaluation unit in order to achieve more extensive control options, but in principle it is also possible to influence only the standard controls of the motors by the signal of the evaluation unit.

In einer weiteren bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass der Primär- und der Sekundärmotor getrennte Stromversorgungen besitzen. In der Regel wird man für die Versorgung des Primärmotors das Haushaltsstromnetz verwenden, d. h. eine landestypische Wechselspannung. Für den Sekundärmotor ist es insbesondere im Hinblick auf einen möglichen Einsatz in einer Notfallsituation vorteilhaft, wenn er über eine vom Haushaltsstromnetz autarke Stromversorgung verfügt, beispielsweise über einen Akkumulator, der ihn mit Gleichstrom speist.In a further preferred embodiment of the invention it is provided that the primary and the secondary motor have separate power supplies. In general, you will use the household power grid for the supply of the primary engine, d. H. a country-specific AC voltage. For the secondary engine, it is particularly advantageous in view of a possible use in an emergency situation, if it has a self-sufficient from the household power supply power, for example, via an accumulator that feeds him with DC.

Zur Vereinfachung der Steuerung kann es zweckmäßig sein, dass der Primärmotor über einen eigenen Endschalter verfügt, der im Normalbetrieb für die Abschaltung der Verfahrbewegung in der eingefahrenen Endlage des Behanges sorgt. Beim langsamen Verstellen des Primärantriebes sind auch die kinetischen Kräfte in der Regel unbedenklich, so dass eine Bremsposition meist nicht ermittelt werden muss. Unabhängig davon bleibt, dass der Messwertgeber auch Verfahrbewegungen durch den Primärantrieb registriert und im Bedarfsfall die absolute Behangstellung dem Sekundärantrieb zur Verfügung stellt, um eine gezielte Abschaltung in der Endlage zu ermöglichen.To simplify the control, it may be appropriate that the primary motor has its own limit switch, which ensures the shutdown of the movement in the retracted end position of the curtain in normal operation. When slowly adjusting the primary drive and the kinetic forces are generally harmless, so that a braking position usually does not need to be determined. Regardless of this, the transmitter also records traversing movements by the primary drive and, if necessary, provides the absolute shutter position to the secondary drive in order to enable targeted shutdown in the end position.

Grundsätzlich ist die Art und Weise, wie die beiden Antriebe auf die Aufzugsvorrichtung der Sonnenschutzanlage wirken frei und von der Art der Sonnenschutzanlage und der Antriebe abhängig. Beide Antriebe können auf eine gemeinsame Antriebswelle wirken, wobei vorzugsweise der Primärantrieb und / oder der Sekundärantrieb über ein Differentialgetriebe oder alternativ über eine elektrisch schaltbare Kupplung mit der Antriebswelle des Primärantriebes gekoppelt ist, um dafür zu sorgen, dass im Normalbetrieb der Sekundärantrieb von der Antriebswelle entkoppelt ist und nicht mit dieser rotiert.Basically, the way in which the two drives act on the elevator device of the sunshade system is free and dependent on the type of sun shading system and the drives. Both drives can act on a common drive shaft, wherein preferably the primary drive and / or the secondary drive is coupled via a differential gear or alternatively via an electrically switchable coupling with the drive shaft of the prime mover to ensure that decoupled from the drive shaft in normal operation of the secondary drive is and not rotated with this.

Häufig sind derartige Sonnenschutzanlagen mit einer Notraffvorrichtung als Raffstoreanlagen ausgebildet, bei welchen der Behang aus einem raffbaren Lamellenpaket mit einer Endschiene besteht, an welcher Aufzugsbänder oder -schnüre festgelegt sind, die auf Wickelrollen in einer Oberschiene der Sonnenschutzanlage aufwickelbar sind.Often, such sun protection systems are designed with a Notraffvorrichtung as external venetian blinds, in which the curtain consists of a gatherable plate pack with a end rail on which elevator belts or cords are fixed, which are wound on bobbins in an upper rail of the sunshade.

Die Abbildungen zeigen eine als Raffstore ausgebildete Sonnenschutzanlage 10 mit einer Oberschiene 12, in welcher ein Primär- oder Hauptantrieb 14 und ein Sekundärantrieb 16 sowie weitere Antriebselemente vorgesehen sind, auf die später noch näher eingegangen wird. Die Antriebe wirken über eine gemeinsame Antriebswelle 18 auf kombinierte Aufzugs-Wendelager 20, die zum einen auf Leiterkordeln 22, an denen Lamellen 24 eines Lamellenbehangs 26 aufgehängt sind, um deren Neigung verstellen zu können, und zum anderen auf Aufzugsbänder 28 wirken, die auf Wickelrollen in den Aufzugsvorrichtungen 20 aufwickelbar sind und durch Öffnungen 30 in den Lamellen 24 bis zu einer Endschiene 32 verlaufen, an welcher sie festgelegt sind.The figures show a trained as Raffstore sun protection system 10 with an upper rail 12, in which a primary or main drive 14 and a secondary drive 16 and other drive elements are provided, which will be discussed in more detail later. The drives act on a common drive shaft 18 on combined elevator coil bearings 20, which on the one hand on conductor cords 22, in which slats 24 a Lamellenbehangs 26 are suspended to adjust their inclination, and on the other lift belts 28 act on bobbins can be wound in the elevator devices 20 and extend through openings 30 in the blades 24 to a end rail 32 to which they are fixed.

Im Normalbetrieb werden die Aufzugslager ausschließlich durch den Primärantrieb 14 verstellt, der beispielsweise über eine Steuerung 34 angesteuert wird. Der Primärantrieb 14 kann über eine integrierte Endabschaltung verfügen, die ihn unabhängig von weiteren Einrichtungen zur Erfassung der Behangposition des Behanges 26 in dessen Endlagen abschaltet.In normal operation, the elevator bearings are adjusted exclusively by the primary drive 14, which is controlled for example via a controller 34. The prime mover 14 may have an integrated limit stop that makes it independent switches off further devices for detecting the Behangposition of the curtain 26 in its end positions.

Der Primärantrieb 14 wirkt unmittelbar auf die Aufzugslager 20, d. h. seine Antriebswelle 18 ist starr mit diesen gekoppelt.The primary drive 14 acts directly on the elevator bearings 20, d. H. its drive shaft 18 is rigidly coupled thereto.

In einem Notfall ist eine Notraffung des Behangs 26 gewünscht, um eine von diesem verschattete Fenster- oder Türfläche schnell freigeben zu können. Hierzu ist der Sekundärantrieb 16 vorgesehen, der über eine durch das zwischen den beiden Antrieben 14, 16 liegende Aufzugs-Wendelager 20 verlaufende Antriebswelle mit einem Differential 36 gekoppelt ist. Dieses Differential 36 vermeidet, dass im Normalbetrieb der Sekundärantrieb 16 bei einem Verstellen des Behangs 26 bewegt wird. Gleichzeitig ermöglicht es aber bei einem Einschalten des Sekundärantriebes 16, das letztere mit der Antriebswelle 18 gekoppelt wird und damit unabhängig von einem Einschalten des Primärantriebes 14 den Behang mit erhöhter Geschwindigkeit raffen kann, z. B. auch wenn der Primärantrieb gerade aktiv ist.In an emergency, a Notraffung the curtain 26 is desired to quickly release a shaded from this window or door area can. For this purpose, the secondary drive 16 is provided which is coupled to a differential 36 via a drive shaft extending through the intermediate drive shaft 20 located between the two drives 14, 16. This differential 36 avoids that the secondary drive 16 is moved during an adjustment of the curtain 26 in normal operation. At the same time, however, it makes it possible at a turn on the secondary drive 16, the latter is coupled to the drive shaft 18 and thus irrespective of switching on the prime mover 14 can catch the curtain with increased speed, z. B. even if the prime mover is currently active.

Da der Sekundärantrieb 16 im Normalfall deaktiviert ist, und lediglich durch das Betätigen eines Auslösetasters, beispielsweise auch eines Auslösetasters 38 für einen Feueralarm aktiviert wird, ist es notwendig, die Einholbewegung des Behanges rechtzeitig zu stoppen, da insbesondere wegen dessen hoher Geschwindigkeit bei einem unkontrollierten Anschlag an der Oberschiene 12 eine Beschädigung oder Zerstörung des Behanges 26 zu befürchten wäre. Hierzu ist im Bereich des Aufzugs-/ Wendelagers 20 zwischen den beiden Antrieben 14, 16 ein Messwertgeber vorgesehen, der jederzeit, d. h. auch bei nicht aktiviertem Sekundärantrieb 16 die Absolutstellung des Behangs anhand der Bewegungen der Aufzugsvorrichtung 20 erfasst und mittels der Steuerung 34 die Absolutposition des Behangs 26 errechnet. Aufgrund dieses jederzeit vorliegenden Absolutwertes kann der Sekundärantrieb 16 dann beim Erreichen der Endanschlagposition gestoppt werden, unabhängig davon, ob die Notraffung aus einer voll ausgefahrenen Endstellung oder einer Zwischenstellung erfolgt ist. Weiterhin ist vorgesehen, dass die Steuerung 34 eine Bremsposition kurz vor Erreichen der oberen Endstellung des Behanges 26 ermittelt und beim Passieren dieser Bremsposition den Sekundärmotor 16 bereits abschaltet oder mithilfe dessen gezielt ein Bremsmoment aufbaut, um die Verstellbewegung des Lamellenbehangs 26 zu verlangsamen und diesen dann schonend in seine Endposition zu bewegen. Dadurch wird verhindert, dass trotz eines Abschaltens des Antriebes in der Endposition die hohe kinetische Energie der Behangteile für Beschädigungen sorgt.Since the secondary drive 16 is normally disabled, and is activated only by pressing a trigger button, for example, a trigger button 38 for a fire alarm, it is necessary to stop the Einholbewegung the curtain in time, especially because of its high speed at an uncontrolled stop at the top rail 12 would be a damage or destruction of the curtain 26 to be feared. For this purpose, a transducer is provided in the area of the elevator / turning bearing 20 between the two drives 14, 16, which detects the absolute position of the curtain on the basis of the movements of the elevator device 20 at any time, ie even with not activated secondary drive 16 and the absolute position of the Behangs 26 calculated. Because of this absolute value at any time can the secondary drive 16 are then stopped when reaching the end stop position, regardless of whether the emergency reaming has taken place from a fully extended end position or an intermediate position. Furthermore, it is provided that the controller 34 determines a braking position shortly before reaching the upper end position of the curtain 26 and the secondary motor 16 already shuts off when passing this braking position or by means of which selectively builds a braking torque to slow the adjustment of the Lamellenbehangs 26 and then gently to move to its final position. This prevents that, despite a shutdown of the drive in the final position, the high kinetic energy of the Behangteile ensures damage.

Prinzipiell kann der Messwertgeber zur Bestimmung der Relativbewegungen des Behangs und damit auch dessen Absolutstellung mithilfe der Steuerung 34 an verschiedenen Anlagenteilen angeordnet sein, die im Regelbetrieb bei einer Verstellung der Ausfahrlänge des Behangs 26 bewegt werden. Insbesondere kann dies auch die Antriebswelle 18 oder ein Teil des Primärantriebes 14 sein.In principle, the sensor for determining the relative movements of the curtain and thus also its absolute position can be arranged with the aid of the control 34 at different plant parts, which are moved during normal operation with an adjustment of the extension length of the curtain 26. In particular, this may also be the drive shaft 18 or a part of the primary drive 14.

Die beschriebene Kombination aus Antrieben in Verbindung mit einer von diesen unabhängigen Erfassung mittels eines Messwertgebers ist auch nicht auf Raffstoren beschränkt, sondern kann in gleicher Weise auch bei Fallmarkisen oder Rollos eingesetzt werden, sofern ein zweiter Antrieb zum Einsatz kommt.The described combination of drives in conjunction with one of these independent detection by means of a transmitter is not limited to external venetian blinds, but can be used in the same way in case of awnings or blinds, if a second drive is used.
