Description

STAND DER TECHNIKSTATE OF THE ART

Die Erfindung betrifft eine elektrische Antriebsvorrichtung für Verdunkelungs- oder Beschattungsvorrichtungen in oder an Gebäuden, wie Rolläden, Jalousien, Rollos, Markisen, Lamellenvorhänge od.dgl., nach der Gattung des Hauptanspruchs.The invention relates to an electric drive device for blackout or shading devices in or on buildings, such as blinds, blinds, Roller blinds, awnings, slatted curtains or the like., According to Genus of the main claim.

Aus der DE 44 20 980 C2 oder der DE 29722936 U1 sind elektrische Antriebsvorrichtung dieser Gattung mit einer Gurtwickelvorrichtung für den Gurt eines Rolladens bekannt. Diese bekannten Antriebsvorrichtungen können in einer Mauerausnehmung anstelle eines handbetriebenen Gurtwicklers eingebaut werden, was sehr kleine Gehäusebauformen erforderlich macht. Demzufolge sollten auch die übrigen Komponenten möglichst klein sein, insbesondere auch der als Elektromotor ausgebildete Antriebsmotor.From DE 44 20 980 C2 or DE 29722936 U1 are electric drive device of this type with a Belt winding device for the belt of a roller shutter known. These known drive devices can in a wall recess instead of a hand-operated one Gurtwicklers are installed, resulting in very small housing designs required. Accordingly, should also the remaining components should be as small as possible, in particular also designed as an electric motor drive motor.

Aus der DE 38 34 643 A geht eine elektrische Antriebsvorrichtung für Vertikaltore hervor, bei der als Motor ein Gleichstrommotor verwendet wird, der hinsichtlich Drehzahl und Drehmoment in weiten Bereichen regelbar ist. Eine Bedienungs- und/oder Einstellmöglichkeit des Motors ist jedoch nicht vorgesehen.From DE 38 34 643 A is an electric drive device for vertical doors, when used as a motor a DC motor is used, with regard to Speed and torque adjustable in wide ranges is. An operating and / or adjustment of the Motors is not provided.

Aus der EP-A-0 808 986 ist eine Steuerung für Antriebe von Toren bekannt mit Mitteln zur Veränderung des Drehmomentes des Antriebsmotors während des Ablaufes oder des Anhebens des Tores, wobei das Drehmoment des Antriebsmotors in Abhängigkeit vom Drehmomentbedarf des Tores gesteuert wird. Damit werden eine schonende Betriebsweise und ein automatisches Stoppen an Hindernissen erreicht.From EP-A-0 808 986 there is a control for drives known by gates with means of altering the Torque of the drive motor during the process or raising the door, wherein the torque of the Drive motor depending on the torque requirement of Tores is controlled. This will be a gentle operation and an automatic stop on obstacles reached.

Eine Verdunkelungsvorrichtung mit einem Rolladen, der mittels eines Elektromotors auf- und abwickelbar ist, geht ferner aus der EP-A-0 092 118 hervor.A darkening device with a roller shutter, the can be wound up and unwound by means of an electric motor, is further apparent from EP-A-0 092 118.

Auch bei anderen bekannten elektrischen Antriebsvorrichtungen, beispielsweise Rohrmotoren oder Antriebsmotoren für Rollos oder Markisen, besteht die Forderung nach einer möglichst kompakten und kleinvolumigen Bauweise, um beispielsweise Wickelwellen mit kleinem Durchmesser verwenden zu können oder damit die elektrische Antriebsvorrichtung optisch nicht störend in Erscheinung tritt.Also in other known electric drive devices, For example, tubular motors or drive motors for blinds or awnings, there is the requirement after a compact and small-volume construction, for example, winding shafts with a small Diameter to use or so the electrical Drive device visually not disturbing in appearance occurs.

Um trotz der kleinen Bauform von Elektromotoren die zur Bewegung der Verdunkelungs- oder Beschattungsvorrichtung erforderlichen Kräfte aufbringen zu können, werden Kleinmotoren mit hoher Drehzahl und entsprechend Untersetzungsgetriebe mit grosser Untersetzung verwendet. Durch diese hohen Drehzahlen mit Getriebeuntersetzung verursachen die sich bewegenden Komponenten abhängig von der Art des Mauerwerks und der Befestigung im oder am Mauerwerk störende Geräusche, die sich durch Körperund Luftschall im Gebäude verbreiten und insbesondere während der Nachtruhe unerwünscht sind. Unabhängig vom Schallpegel werden die mit hohen Drehzahlen verbundenen Frequenzen subjektiv meistens als störend empfunden.In spite of the small design of electric motors to the Movement of the dimming or shading device be able to raise the necessary forces Small motors with high speed and corresponding reduction gear used with large reduction. Due to these high speeds with gear reduction cause the moving components to be dependent on the type of masonry and the attachment in or on the masonry disturbing noises, which are due to Körperund Airborne sound spread in the building and in particular during sleep are unwanted. Independent of Sound levels are those associated with high speeds Frequently subjectively perceived frequencies as annoying.

VORTEILE DER ERFINDUNGADVANTAGES OF THE INVENTION

Die erfindungsgemässe elektrische Antriebsvorrichtung mit den kennzeichnenden Merkmalen des Hauptanspruchs hat den Vorteil, dass die Drehzahl des in der Antriebsvorrichtung vorhandenen Elektromotors entsprechend den individuellen Gegebenheiten in den meisten Fällen herabgesetzt werden kann, wobei immer noch eine ausreichende Antriebsleistung vorhanden ist. Die Elektromotoren müssen nämlich so ausgelegt werden, dass sie auch bei ungünstigsten Verhältnissen noch eine ausreichende Antriebsleistung zur Verfügung stellen können, beispielsweise für sehr grossflächige Rolläden aus schwerem Material, wie Holz oder Metall. Häufig benötigen auch ältere Rolläden, die mit einer Antriebsvorrichtung nachgerüstet werden, eine besonders hohe Antriebsleistung, da sie neben ihrer grossen Masse häufig auch noch schwergängig sind. Wenn nun eine solche für ungünstigste Verhältnisse ausgelegte Antriebsvorrichtung für einen kleinen, leichtgewichtigen und leichtgängigen Rolladen eingesetzt wird, so kann die Antriebsleistung erfindungsgemäss durch Drehzahlreduzierung wesentlich herabgesetzt werden, wobei dann immer noch eine ausreichende Antriebsleistung zur Verfügung steht. Diese Absenkung der Drehzahl führt zur angestrebten Geräuschreduzierung. Die Herabsetzung der Drehzahl kann somit individuell in Abhängigkeit der vorgenommenen Gegebenheiten erfolgen, so dass jeweils eine maximale Geräuschreduzierung erreicht werden kann. Die infolge der Herabsetzung der Drehzahl reduzierte Antriebsleistung führt zusätzlich auch zu einer Energieeinsparung, was sich vor allem bei Batteriebetrieb oder Solarbetrieb als besonders vorteilhaft erweist. Neben der Geräuschreduzierung durch geringere Motor- und Getriebegeräusche werden auch durch die langsameren Bewegungen die Geräusche der Verdunkelungseinrichtung oder Beschattungsvorrichtung selbst reduziert. Damit verbunden ist ein auch ein schonenderer Betrieb der sich bewegenden Komponenten und eine entsprechend längere Lebensdauer.The inventive electric drive device with the characterizing features of the main claim has the advantage that the speed of the in the drive device existing electric motor according to the individual circumstances in most cases reduced can still be a sufficient Drive power is available. The electric motors must be designed so that they too in unfavorable conditions still sufficient Drive power can provide, for example for very large blinds made of heavy Material, such as wood or metal. Often need also older blinds, with a drive device be retrofitted, a particularly high drive power, because they often also in addition to their large mass are still difficult. If now such a worst case Conditions designed drive device for a small, lightweight and smooth-running Roller shutters is used, so the drive power According to the invention by speed reduction essential be reduced, and then still sufficient Drive power is available. This lowering The speed leads to the desired noise reduction. The reduction of the speed can thus individually depending on the circumstances done so that each one maximum noise reduction can be achieved. The result of the reduction the speed reduced drive power leads In addition to energy savings, which is especially with battery operation or solar operation as special proves advantageous. In addition to the noise reduction due to lower engine and transmission noise also by the slower movements the noises the dimming device or shading device even reduced. Related to this is also a more gentle operation of the moving components and a correspondingly longer life.

Durch die in den Unteransprüchen aufgeführten Massnahmen sind vorteilhafte Weiterbildungen und Verbesserungen der im Hauptanspruch angegebenen Antriebsvorrichtung möglich.By the measures listed in the dependent claims are advantageous developments and improvements the drive device specified in the main claim possible.

Die Bedienungs- und/oder Einstellmittel sind mindestens teilweise zur Vorgabe wenigstens einer gewünschten Drehzahl, insbesondere eines Drehzahl-Sollwerts, ausgebildet, so dass dieser sehr schnell und einfach vorgewählt und auch verändert werden kann, um beispielsweise eine weitere Drehzahlabsenkung zu testen oder bei einer erfolgten zu starken Drehzahlabsenkung diese wieder nach oben zu korrigieren. Die Bedienungs- und/oder Einstellmittel weisen dabei zweckmässigerweise eine Tastatur und/oder einen Drehsteller auf.The operating and / or adjusting means are at least partly to specify at least one desired Speed, in particular a speed setpoint formed, making it very quick and easy to select and also can be changed, for example to test another speed reduction or at a Too strong speed reduction made this again to correct upward. The operating and / or adjusting means have expediently a keyboard and / or a turntable on.

Die Antriebsvorrichtung bzw. ein darin enthaltener Mikrorechner weist vorzugsweise nichtflüchtige Speichermittel zur Speicherung wenigstens eines vorgegebenen Drehzahl-Sollwerts auf.The drive device or a microcomputer contained therein preferably has non-volatile storage means for storing at least one predetermined Speed setpoint.

Zur Erfassung des Drehzahl-Istwerts für die Drehzahlregelung ist zweckmässigerweise ein Drehzahlsensor an der Motorwelle an einem Getrieberad des Untersetzungsgetriebes oder an einer Wickelvorrichtung, beispielsweise für ein Gurtband, angeordnet. Alternativ hierzu kann der Drehzahl-Istwert auch über Messmittel für den Motorstrom durch Auswertemittel erfasst werden.For recording the speed feedback value for the speed control is expediently a speed sensor on the Motor shaft on a gear wheel of the reduction gear or on a winding device, for example for a webbing, arranged. Alternatively, it can the actual speed also via measuring device for the motor current be detected by evaluation.

Es hat sich weiterhin als vorteilhaft erwiesen, für unterschiedliche Betriebszustände und/oder Zeiten unterschiedliche Drehzahl-Sollwerte vorzugeben. Beispielsweise ist bei einem Rolladen die erforderliche Leistung beim Aufwickeln erheblich grösser als beim Abwickeln. It has also proven to be beneficial for different Operating conditions and / or times different Specify speed setpoints. For example is the required power for a roller shutter when winding much larger than when unwinding.

Entsprechend können für diese beiden Betriebszustände unterschiedliche Drehzahl-Sollwerte vorgegeben werden, das heisst, das Abwickeln erfolgt dann bei geringerer Drehzahl und entsprechend stärkerer Geräuschreduzierung. Eine weitere Möglichkeit besteht darin, beispielsweise bei Nacht oder während anderer Ruhezeiten die maximal mögliche Drehzahlreduzierung vorzunehmen, während in anderen Zeiten, zu denen die Geräusche keine so grosse Rolle spielen, eine höhere Drehzahl vorgegeben wird.Accordingly, for these two operating states different speed setpoints are specified, that is, the unwinding then takes place at lesser Speed and correspondingly greater noise reduction. Another possibility is, for example at night or during other rest periods to make the maximum possible speed reduction, while in other times, to which the noises play such a big role, given a higher speed becomes.

Die Regelungs- oder Steuereinrichtung für die Drehzahl ist zweckmässigerweise in der ohnehin vorhandenen allgemeinen Steuerelektronik für die elektrische Antriebsvorrichtung integriert. Da eine Drehzahlerfassung auch bei bekannten Antriebsvorrichtungen bereits vorhanden ist, kann im Falle der Ausführung durch einen Mikrorechner die Erfindung allein durch zusätzliche Programmierung realisiert werden, ohne dass die Hardware verändert werden müsste.The regulation or control device for the speed is conveniently in the already existing general Control electronics for the electric drive device integrated. As a speed detection also already present in known drive devices is, in the case of execution by a microcomputer the invention alone by additional programming be realized without changing the hardware would have to be.

ZEICHNUNGDRAWING

Ein Ausführungsbeispiel der Erfindung ist in.der Zeichnung dargestellt und in der nachfolgenden Beschreibung näher erläutert. Die einzige Figur zeigt eine vereinfachte Blockdarstellung einer elektrischen Antriebsvorrichtung für einen Rolladen als Ausführungsbeispiel der Erfindung. An embodiment of the invention is in.der drawing shown and in the following description explained in more detail. The single figure shows a simplified Block diagram of an electric drive device for a roller shutter as an embodiment of Invention.

BESCHREIBUNG DES AUSFÜHRUNGSBEISPIELSDESCRIPTION OF THE EMBODIMENT

Die einzige Figur zeigt eine elektrische Antriebsvorrichtung für einen schematisch dargestellten Rolladen, bei dem ein Rolladenpanzer 10 auf einer Wickelwelle 11 auf- und abwickelbar ist. Ein in einem Gehäuse 12 angeordneter elektrischer Antriebsmotor 13 treibt über ein untersetzungsgetriebe 14 die Wickelwelle 11 an, beispielsweise mittels eines Gurts 15. Das Gehäuse 12 kann beispielsweise gemäss dem eingangs angegebenen Stand der Technik ausgebildet sein, das heisst, es kann zumindest teilweise in eine Mauerausnehmung anstelle eines handbetriebenen Gurtwicklers eingebaut werden, wobei ein die Mauerausnehmung überdeckender flacher Gehäusebereich mit der Mauer verschraubt wird. Ein mit der Wickelwelle 11 in Wirkverbindung stehender Gurt mündet im Gehäuse 12 und wird dort mittels einer nicht dargestellten Gurthaspel auf- und abgewickelt. Der mit der Gurthaspel versehene Gehäusebereich greift dabei üblicherweise in die Mauerausnehmung ein.The single figure shows an electric drive device for a shutter, shown schematically, in which a roller shutter 10 on a winding shaft 11th can be wound up and unwound. An arranged in a housing 12 Electric drive motor 13 drives over reduction gear 14, the winding shaft 11, for example by means of a belt 15. The housing 12 can for example, according to the above-mentioned state be formed of technology, that is, it can at least partly in a wall recess instead of a hand-operated Gurtwicklers be incorporated, wherein a flat housing area covering the wall recess is bolted to the wall. One with the winding shaft 11 operatively connected belt opens in the housing 12 and is there by means of a not shown Gurthaspel up and unwound. The one with the Gurthaspel provided housing area engages usually in the wall recess.

Das Gehäuse enthält weiterhin eine Motorsteuerelektronik 16, die beispielsweise als Mikrorechner ausgebildet ist oder einen solchen enthält. Zur Bedienung dient ein Bedien- und Anzeigefeld 17, das aussen am Gehäuse angeordnet und von dort aus bedienbar bzw. ablesbar ist. Das Anzeigefeld kann dabei als Display oder Leuchtdiodenanordnung ausgebildet sein oder bei einer einfachen Ausführung auch entfallen. Das Bedienfeld besitzt mehrere Bedientasten, kann jedoch alternativ oder zusätzlich auch einen Drehsteller besitzen.The housing also contains motor control electronics 16, for example, designed as a microcomputer is or contains such. For operation serves a Control and display panel 17, the outside of the housing and from there is operable or readable. The display panel can be used as a display or LED array be educated or in a simple Design also omitted. The control panel has several control buttons, but may alternatively or additionally also own a turntable.

In der Motorsteuerelektronik 16 ist eine Drehzahlregelungseinrichtung 18 integriert. Mittels des Bedien- und Anzeigefelds 17 kann ein Drehzahl-Sollwert in einen nichtflüchtigen Speicher 19 der Motorsteuerelektronik 16 eingegeben werden. Der Drehzahl-Istwert wird mittels einer Drehzahlerfassungseinrichtung 20 erfasst und der Drehzahlregelungseinrichtung 18 zugeführt. Die Drehzahlerfassung kann dabei optisch, induktiv oder mittels Hall-Effekt an der Motorwelle, einem Getriebezahnrad des Untersetzungsgetriebes 14, der Abtriebswelle oder der Gurthaspel erfolgen. Alternativ hierzu kann auch der Motorstrom des Antriebsmotors 13 gemessen und daraus die Drehzahl anhand einer in der Motorsteuerelektronik 16 gespeicherten Motorkennlinie bestimmt werden.In the engine control electronics 16 is a speed control device 18 integrated. By means of the operating and Display field 17 can be a speed setpoint in a nonvolatile memory 19 of the engine control electronics 16 are entered. The actual speed value is determined by a speed detection device 20 detected and the Speed control device 18 supplied. The speed detection can be optical, inductive or by means of Hall effect on the motor shaft, a transmission gear the reduction gear 14, the output shaft or the belt reel done. Alternatively, you can the motor current of the drive motor 13 measured and therefrom the speed based on a in the engine control electronics 16 stored motor characteristic can be determined.

Derartige elektrische Antriebsvorrichtungen müssen für maximal auftretende Kräfte und Belastungen ausgelegt sein, das heisst für sehr schwere, grossflächige und schwergängige Rolläden oder andere Verdunkelungs- oder Beschattungsvorrichtungen. Wird die Antriebsvorrichtung nun beispielsweise für einen kleinen, leichten und leichtgängigen Rollladen eingesetzt, so ist die Antriebsvorrichtung leistungsmässig überdimensioniert. Um die maximal mögliche Leistung abzugeben und gleichzeitig eine kleine Bauweise realisieren zu können, werden üblicherweise Kleinmotoren mit sehr hoher Drehzahl und Untersetzungsgetriebe mit grossem Untersetzungsverhältnis eingesetzt. Diese Drehzahlen verursachen Lärmbelästigungen durch Körper- und Luftschall im Gebäude, beispielsweise über den Kontakt mit dem Mauerwerk, Halteschrauben im Mauerwerk oder Schallabstrahlungen in den Raum. Diese Lärmbelästigung kann nun durch Absenken der Drehzahl des Antriebsmotors 13 abgesenkt werden. Die Drehzahl kann dabei so weit abgesenkt werden, bis gerade noch die erforderliche Leistung abgegeben werden kann. Dies kann versuchsweise erfolgen, durch nacheinander erfolgende Eingaben verschiedener Drehzahl-Sollwerte in den Speicher 19. Der Auf- und Abwickelvorgang verlangsamt sich dadurch zwar, jedoch kann dies nach individuellen Bedürfnissen oder Empfindungen mehr oder weniger in Kauf genommen werden. Jedenfalls ist eine beliebige individuelle Anpassung an die jeweiligen Leistungserfordernisse möglich.Such electrical drive devices must be for designed maximum forces and loads be, that means for very heavy, large and large stiff blinds or other blackout or blinds Shading devices. Will the drive device now for example for a small, light and smooth-running shutters used, so is the drive device in terms of performance oversized. Around to give the maximum possible performance and at the same time to be able to realize a small construction usually small engines with very high speed and Reduction gearbox with large reduction ratio used. These speeds cause noise pollution through body and airborne sound in the building, for example about contact with the masonry, retaining screws in the masonry or sound radiation in the Room. This noise pollution can now be reduced by lowering the Speed of the drive motor 13 are lowered. The Speed can be lowered so far, until just still the required power will be delivered can. This can be done tentatively, by successive successive inputs of various speed setpoints in the memory 19. The winding and unwinding process This slows down, but it can according to individual needs or sensations more or less. Anyway Any individual adaptation to the respective Performance requirements possible.

Bei komfortableren Ausführungen können auch mehrere verschiedene Drehzahl-Sollwerte in den Speicher 19 eingegeben werden, die für verschiedene Betriebszustände wirksam sind. So wird beispielsweise für den Abwickelvorgang eines Rolladenpanzers wesentlich weniger Leistung benötigt als für den Aufwickelvorgang. Für den Abwickelvorgang kann daher ein wesentlich niedrigerer Drehzahl-Sollwert vorgegeben werden gegenüber einem Drehzahl-Sollwert für den Aufwickelvorgang. Weiterhin kann während der Nacht oder anderer Ruhezeiten ein gerade noch vertretbarer, sehr niedriger Drehzahl-Sollwert vorgegeben werden, um eine möglichst grosse Geräuschminderung zu erzielen, wobei eine sehr langsame Bewegung in Kauf genommen wird. Dagegen kann für die übrigen Zeiten ein höherer Drehzahl-Sollwert vorgegeben werden, um bei etwas höherer Geräuschbelastung schnellere Bewegungen des Rolladenpanzers zu erzielen.In more comfortable versions can also several various speed setpoints entered into the memory 19 which are for different operating conditions are effective. For example, for the unwinding process a roller shutter tank significantly less power needed as for the winding process. For the Unwinding can therefore be much lower Speed setpoint are given to a Speed setpoint for the rewinding process. Farther can be just during the night or other rest periods still acceptable, very low speed setpoint be given to the largest possible To achieve noise reduction, being a very slow Movement is accepted. On the other hand, for the remaining times specified a higher speed setpoint be faster at slightly higher noise levels To achieve movements of the roller shutter.

In einer einfacheren Ausführung kann anstelle einer Drehzahlregelungseinrichtung eine einfachere Steuereinrichtung treten, wobei die Drehzahl beispielsweise mittels eines Drehstellers eingestellt wird.In a simpler version, instead of a Speed control device a simpler control device occur, wherein the speed, for example by means of a turntable is set.

Die Erfindung ist selbstverständlich nicht auf die Anwendung für Rolläden beschränkt, sondern entsprechende Antriebsvorrichtungen können auch für andere Verdunkelungs- oder Beschattungsvorrichtungen in oder an Gebäuden eingesetzt werden, wie Jalousien, Rollos, Markisen, Lamellenvorhänge od.dgl.Of course, the invention is not limited to the application limited for blinds, but appropriate Drive devices can also be used for other dimming or shading devices in or on buildings be used, such as blinds, roller blinds, awnings, Louvre curtains or the like.
