Description
Die vorliegende Erfindung betrifft eine Anordnung mit wenigstens einer bewegbaren Schublade, mit wenigstens einer Antriebseinheit und mit wenigstens einer Regeleinrichtung zur Regelung der wenigstens einen Antriebseinheit.The present invention relates to an arrangement with at least one movable drawer, with at least one drive unit and with at least one control device for controlling the at least one drive unit.
Derartige Anordnungen sind grundsätzlich bereits bekannt. Die
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Anordnung zu schaffen, die ein intuitives Bedienen einer durch eine Antriebseinheit angetriebenen bewegbaren Schublade ermöglicht.Object of the present invention is to provide a generic arrangement that allows intuitive operation of a driven by a drive unit movable drawer.
Dies wird erfindungsgemäß dadurch erreicht, dass die Anordnung wenigstens eine, vorzugsweise analoge, Beschleunigungsmesseinrichtung aufweist, wobei die wenigstens eine Beschleunigungsmesseinrichtung ein für durch von außen an die bewegbare Schublade angelegte Kräfte verursachte Beschleunigungen charakteristisches Beschleunigungssignal erzeugt, welches der wenigstens einen Regeleinrichtung zuführbar ist.This is inventively achieved in that the arrangement comprises at least one, preferably analog, acceleration measuring device, wherein the at least one acceleration measuring device generates a for acceleration caused by externally applied to the movable drawer forces accelerations characteristic acceleration signal which is the at least one control device can be fed.
Technisch vorteilhaft ist daran, dass bei der erfindungsgemäßen Anordnung keinerlei Betätigungselemente zur Auslösung der Antriebseinheit für die bewegbaren Schubladen mehr vorgesehen sind. Wirtschaftlich vorteilhaft ist daran, dass eine größere Akzeptanz der erfindungsgemäßen Anordnung am Markt zu erwarten ist.Technically advantageous is that in the arrangement according to the invention no actuating elements for triggering the drive unit for the movable drawers are provided more. Economically advantageous is that a greater acceptance of the arrangement according to the invention is expected on the market.
Es ist nicht von Bedeutung ob die Beschleunigung direkt gemessen oder aus anderen gemessenen Größen errechnet wird. In diesem Sinne stellt auch eine Einrichtung zur Positionsbestimmung der bewegbaren Schublade zusammen mit einer Uhr eine Beschleunigungsmesseinrichtung dar. In diesem Fall kann aus der in einer gewissen Zeitspanne zurückgelegten Strecke die Geschwindigkeit und aus der Änderung der Geschwindigkeit die Beschleunigung bestimmt werden.It does not matter if the acceleration is measured directly or calculated from other measured quantities. In this sense, a device for determining the position of the movable drawer together with a clock is also an acceleration measuring device. In this case, the speed can be determined from the distance traveled in a certain period of time and the acceleration from the change in the speed.
Erfindungsgemäß genügt aber bereits das Erkennen der Tatsache, dass eine Beschleunigung der bewegbaren Schublade erfolgt ist, unabhängig vom Betrag oder der Richtung der Beschleunigung.According to the invention, however, it is sufficient to recognize the fact that an acceleration of the movable drawer has taken place, regardless of the magnitude or the direction of the acceleration.
Günstigerweise ist in einer Ausführungsform der Erfindung vorgesehen, dass die wenigstens eine Antriebseinheit einen elektrischen Motor umfasst. Derartige elektrische Motoren sind in Kleinstbauweise kommerziell erhältlich und garantieren bei geringem Strombedarf einen problemlosen Betrieb.Conveniently, in one embodiment of the invention, it is provided that the at least one drive unit comprises an electric motor. Such electric motors are commercially available in miniature construction and guarantee trouble-free operation with low power consumption.
Eine besonders vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, dass das Beschleunigungssignal Informationen über den Betrag und/oder über die Richtung, vorzugsweise über die Richtungskomponente parallel zur Auszugsrichtung der bewegbaren Schublade der durch von außen an die bewegbare Schublade angelegten Kräfte verursachten Beschleunigung beinhaltet. Damit kann die Beschleunigungsmesseinrichtung der Regeleinrichtung Informationen darüber zur Verfügung stellen, in welche Richtung die Betätigung der Schublade erfolgen soll. Erhält die Regeleinrichtung beispielsweise von der Beschleunigungsmesseinrichtung das Signal einer vorliegenden Zugbeschleunigung, kann sie der Antriebseinheit sofort einen Steuerbefehl zum Bewegen des bewegbaren Möbelteils in Richtung der gemessenen Zugbeschleunigung zusenden. Dabei spielt es an und für sich keine Rolle, in welchem Öffnungszustand sich die Schublade zum Zeitpunkt der externen Betätigung befindet. Günstigerweise ist aber vorgesehen, dass in einem gewissen Bereich vor der geöffneten sowie der geschlossenen Endlage der bewegbaren Schublade keine angetriebene Bewegung der Schublade mehr erfolgt, um eine Beschädigung der Schublade bzw. der erfindungsgemäßen Anordnung zu verhindern. Dazu ist es vorteilhaft, dass die Anordnung mindestens eine Positionsmesseinrichtung aufweist, welche ein für den Öffnungszustand der bewegbaren Schublade charakteristisches und der Regeleinrichtung zuführbares Positionssignal erzeugt. So kann die Regeleinrichtung zu jeder Zeit erkennen, ob sich die bewegbare Schublade in der Nähe einer der Endlagen befindet.A particularly advantageous embodiment of the invention results from the fact that the acceleration signal includes information about the amount and / or the direction, preferably via the direction component parallel to the extension direction of the movable drawer caused by externally applied to the movable drawer forces acceleration. Thus, the acceleration measuring device of the control device can provide information about the direction in which the operation of the drawer is to take place. Receives the control device, for example, the acceleration measuring device, the signal of a present train acceleration, it can send the drive unit immediately a control command for moving the movable furniture part in the direction of the measured train acceleration. It does not matter in which opening state the drawer is at the time of external actuation. Conveniently, however, provided that in a certain range before the open and the closed end position of the movable drawer no driven movement of the drawer takes place more to prevent damage to the drawer or the inventive arrangement. For this it is advantageous that the Arrangement comprises at least one position measuring device which generates a characteristic of the opening state of the movable drawer and the control device feedable position signal. Thus, the controller can detect at any time, whether the movable drawer is located near one of the end positions.
Vorteilhafterweise beinhaltet das Beschleunigungssignal, das von der Beschleunigungsmesseinrichtung an die Regeleinrichtung ergeht, auch Informationen über den Betrag der vom Benutzer ausgeübten Beschleunigung der bewegbaren Schublade. Aus einem großen Betrag der Beschleunigung kann beispielsweise geschlossen werden, dass ein rasches Öffnen bzw. Schließen gewünscht wird, wodurch die Regeleinheit die Antriebseinheit der Situation entsprechend betätigen kann.Advantageously, the acceleration signal applied by the accelerometer to the controller also includes information about the amount of user-applied acceleration of the movable drawer. For example, it can be concluded from a large amount of acceleration that a rapid opening or closing is desired, whereby the control unit can actuate the drive unit according to the situation.
Eine vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, dass die Antriebseinheit die bewegbare Schublade über eine vorgegebene Zeitspanne annähernd gleichmäßig beschleunigt. Dadurch, dass die Beschleunigung der bewegbaren Schublade nur über eine vorgegebene Zeitspanne erfolgt, wird für den Benutzer die Illusion einer nicht angetriebenen Schublade aufrechterhalten. Nach Ablauf der Zeitspanne wird die bewegbare Schublade durch die systembedingte Reibung abgebremst, ganz so, als ob keine Antriebseinheit vorhanden wäre. Es könnte allerdings auch vorgesehen sein, dass nach der Beschleunigungszeitspanne eine geringere Beschleunigung zum Ausgleich der durch die Reibung verursachten Bremsung aufrechterhalten wird. Dadurch wird der Eindruck einer nicht angetriebenen Schublade aufrechterhalten, das beispielsweise besonders reibungsarm gelagert ist. Alternativ oder ergänzend kann auch vorgesehen sein, dass die Antriebseinheit die bewegbare Schublade nur über einen vorgebbaren bzw, vorgegebenen Teilweg, dessen Länge kleiner ist als die Länge des Gesamtweges zwischen der geschlossenen und der geöffneten Endlage der bewegbaren Schublade, beschleunigt. Dadurch, dass die Antriebseinheit nicht über den gesamten Öffnungsweg aktiv ist, wird die angestrebte Unsichtbarkeit der Technik beibehalten.An advantageous embodiment of the invention results from the fact that the drive unit accelerates the movable drawer approximately uniformly over a predetermined period of time. Characterized in that the acceleration of the movable drawer takes place only over a predetermined period of time, the illusion of a non-driven drawer is maintained for the user. After the expiry of the period, the movable drawer is slowed down by the system-related friction, as if no drive unit were present. However, it could also be provided that after the acceleration period, a lower acceleration to compensate for the friction caused by the braking is maintained. As a result, the impression of a non-driven drawer is maintained, which is stored, for example, very low friction. Alternatively or additionally, it can also be provided that the drive unit accelerates the movable drawer only via a predefinable or predetermined partial path whose length is smaller than the length of the total path between the closed and the open end position of the movable drawer. The fact that the drive unit is not active over the entire opening path, the desired invisibility of the technology is maintained.
Es kann auch vorgesehen sein, dass die Bewegung der bewegbaren Schublade durch die Antriebseinheit unabhängig vom Betrag der Zug- oder Druckbeschleunigung ist. Dadurch entscheidet allein der Benutzer durch den Betrag seiner Kraftaufwendung, wie schnell die Bewegung der bewegbaren Schublade erfolgen soll, wobei von der Antriebseinheit immer dieselbe unterstützende Beschleunigung erfolgt.It can also be provided that the movement of the movable drawer by the drive unit is independent of the amount of tensile or compressive acceleration. As a result, the user alone decides, by the amount of his effort, how quickly the movement of the movable drawer should take place, with the same assisting acceleration always taking place by the drive unit.
Eine besonders vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, dass die Regeleinrichtung eine Istwertberechnungseinrichtung aufweist, welche aus dem von der Positionsmesseinrichtung erzeugten Positionssignal, die momentane Istposition und/oder die momentane Istgeschwindigkeit des bewegbaren Möbelteils berechnet. Durch die Kenntnis der momentanen Position und Geschwindigkeit der bewegbaren Schublade ist es möglich, auf definierten Teilstrecken, beispielsweise in der Nähe der Endlagen der bewegbaren Schublade, durch die Antriebseinheit eine Beschleunigung derart vorzunehmen, dass die bewegbare Schublade in der jeweiligen Endlage zum Stillstand kommt.A particularly advantageous embodiment of the invention results from the fact that the control device has an actual value calculation device, which calculates from the position signal generated by the position measuring device, the instantaneous actual position and / or the instantaneous actual speed of the movable furniture part. By knowing the current position and speed of the movable drawer, it is possible to perform on defined sections, for example in the vicinity of the end positions of the movable drawer, by the drive unit, an acceleration such that the movable drawer comes to a standstill in the respective end position.
Bei der Erfindung ist vorgesehen, dass die bewegbare Schublade bewegbar an seitlich innerhalb der Anordnung angeordneten Zargen gelagert ist. Derartige Zargen, die für sich genommen Stand der Technik sind, erlauben die reibungsarme und sichere Lagerung der bewegbaren Schublade in der erfindungsgemäßen Anordnung.In the invention, it is provided that the movable drawer is movably mounted on frames arranged laterally within the arrangement. Such frames, which are state of the art in their own right, allow the low-friction and secure mounting of the movable drawer in the arrangement according to the invention.
Bei der Erfindung ist auch vorgesehen, dass die Antriebseinheit an einer Zarge angebracht ist. Dadurch kann beispielsweise für jedes bewegbare Schublade eine eigene Antriebseinheit zur Verfügung gestellt werden.In the invention it is also provided that the drive unit is attached to a frame. As a result, for example, a separate drive unit can be provided for each movable drawer.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass die Antriebseinheit in ständiger Verbindung mit der bewegbaren Schublade steht. Dadurch ist die Beschleunigung der bewegbaren Schublade durch die Antriebseinheit unabhängig von der momentanen Lage der bewegbaren Schublade in Bezug auf die erfindungsgemäße Anordnung möglich. Dafür bietet sich beispielsweise an, dass die Antriebseinheit über wenigstens ein Seil oder einen Riemen, vorzugsweise Zahnriemen, oder über ein in eine Zahnstange eingreifendes Zahnrad in ständiger Verbindung mit der bewegbaren Schublade steht. Die Verwendung eines Zahnriemens garantiert dabei die schlupffreie Verbindung zwischen der bewegbaren Schublade und der Antriebseinheit. Die Kraftausübung kann beispielsweise dadurch erfolgen, dass der Riemen über wenigstens zwei Rollen läuft, die an einer seitlichen Zarge angeordnet sind. Natürlich können auch beide seitlichen Zargen mit wenigstens zwei Rollen ausgeführt sein, über die jeweils ein Riemen zur Kraftübertragung geführt wird. Natürlich wäre auch die Verwendung eines Seils ohne Schlupf möglich, wenn auf der angetriebenen Rolle beide Seilenden fixiert sind und somit gleichzeitig das eine Seilende abgewickelt und das andere Seilende aufgewickelt wird.In a further advantageous embodiment of the invention it is provided that the drive unit is in constant communication with the movable drawer. As a result, the acceleration of the movable drawer by the drive unit is independent of the current position of the movable drawer with respect to the invention Arrangement possible. For example, it is advisable for the drive unit to be in constant communication with the movable drawer via at least one cable or a belt, preferably a toothed belt, or via a toothed wheel engaging in a toothed rack. The use of a toothed belt guarantees the slip-free connection between the movable drawer and the drive unit. The exercise of force can for example take place in that the belt runs over at least two rollers, which are arranged on a side frame. Of course, both side frames can be designed with at least two rollers, over each of which a belt is guided for power transmission. Of course, the use of a rope without slippage would be possible if both ends of the rope are fixed on the driven roller and thus at the same time one end of the rope unwound and the other end of the rope is wound up.
Ab einer gewissen Breite der bewegbaren Schublade ist es vorteilhaft, dass wenigstens zwei an unterschiedlichen Zargen angeordnete Rollen über eine Verbindungswelle miteinander in - vorzugsweise starrer - Verbindung stehen und so durch die Antriebseinheit bewegbar sind.From a certain width of the movable drawer, it is advantageous that at least two rollers arranged on different frames are connected to one another via a connecting shaft - preferably a rigid connection - and thus are movable by the drive unit.
Eine weitere vorteilhafte Ausführungsform der Erfindung ergibt sich dadurch, dass wenigstens eine Rolle an wenigstens einer Zarge durch die Antriebseinheit antreibbar ist. Dies gestattet eine verlustärmere Kraftübertragung als bei der Zwischenschaltung von Übertragungseinrichtungen zwischen der Antriebseinheit und der bewegbaren Schublade erzielbar wäre.A further advantageous embodiment of the invention results from the fact that at least one roller can be driven by the drive unit on at least one frame. This allows a lower-loss power transmission than would be achievable with the interposition of transmission devices between the drive unit and the movable drawer.
Um eine günstigere Übersetzung der Bewegung der Antriebseinheit auf die bewegbare Schublade zu erzielen, kann vorgesehen sein, dass die wenigstens eine Rolle an wenigstens einer Zarge über ein Getriebe durch die Antriebseinheit antreibbar ist. Bei einer breiten bewegbaren Schublade bietet es sich wieder an, an beiden Enden der Verbindungswelle Getriebe vorzusehen. Bei sehr breiten bewegbaren Schubladen kann auch vorgesehen sein, an beiden Seiten der bewegbaren Schublade Antriebseinheiten anzuordnen, die entweder über eigene Regelungseinrichtungen sowie eine Synchronisierungsvorrichtung verfügen oder von einer gemeinsamen Regelungsvorrichtung angesteuert werden.In order to achieve a more favorable translation of the movement of the drive unit to the movable drawer, it can be provided that the at least one roller is drivable on at least one frame via a transmission by the drive unit. With a wide movable drawer, it is again advisable to provide transmission at both ends of the connecting shaft. For very wide movable drawers can also be provided to arrange on both sides of the movable drawer drive units, which either have their own control devices and a synchronization device or are controlled by a common control device.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung kann vorgesehen sein, dass die Anordnung einen Resolver zur Messung der Position und/oder der Geschwindigkeit und/oder der Beschleunigung der bewegbaren Schublade umfasst, dessen Signale der Regeleinrichtung zuführbar sind. Derartige Resolver sind kommerziell erhältlich und mechanisch sowie thermisch äußerst robust. Ein derartiger Resolver ist nach dem Drehtransformatorprinzip aufgebaut. Handelsübliche Resolver sind häufig mit integrierter Auswerteschaltung erhältlich, sodass deren Signal direkt der Regeleinrichtung zugeführt werden kann.In a further advantageous embodiment of the invention it can be provided that the arrangement comprises a resolver for measuring the position and / or the speed and / or the acceleration of the movable drawer, the signals of which can be supplied to the control device. Such resolvers are commercially available and extremely robust mechanically and thermally. Such a resolver is after the Built rotary transformer principle. Commercially available resolvers are often available with an integrated evaluation circuit, so that their signal can be fed directly to the control device.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung kann vorgesehen sein, dass die Anordnung einen optischen Encoder zur Messung der Position und/oder der Geschwindigkeit und/oder der Beschleunigung des bewegbaren Möbelteils umfasst, dessen Signale der Regeleinrichtung zuführbar sind. Derartige optische oder auch magnetische Encoder stellen eine preisgünstige und häufig auch Raum sparende Alternative zu den Resolvern dar. Dabei garantieren sie immer noch einen für eine erfindungsgemäße Anordnung zufrieden stellenden Winkelauflösungsbereich, beispielsweise von 64 bis 1024 Impulsen/Umdrehung. Gewisse Nachteile bei optischen und magnetischen Encodern ergeben sich aus deren Empfindlichkeit gegenüber mechanischen Vibrationen, Verschmutzungen und dem Fehlen einer absoluten Winkelinformation zum Einschaltzeitpunkt, sodass derartige Encoder nur inkrementale Positionsbestimmungen vornehmen können.In a further advantageous embodiment of the invention can be provided that the arrangement comprises an optical encoder for measuring the position and / or the speed and / or the acceleration of the movable furniture part, the signals of the control device can be fed. Such optical or even magnetic encoders represent an inexpensive and frequently also space-saving alternative to the resolvers. They still guarantee an angular resolution range which is satisfactory for an arrangement according to the invention, for example from 64 to 1024 pulses / revolution. Certain disadvantages with optical and magnetic encoders arise from their sensitivity to mechanical vibrations, contamination and the lack of absolute angle information at the time of switch-on, so that such encoders can only make incremental position determinations.
Bei einer weiteren vorteilhaften Ausführungsform der Erfindung ist vorgesehen, dass die Antriebseinheit einen bürstenlosen Gleichstrommotor umfasst und die Messung der Position und/oder der Geschwindigkeit und/oder der Geschwindigkeit und/oder der Beschleunigung der bewegbaren Schublade direkt über das Kommutatorsignal erfolgt, wobei die derart gewonnenen Signale der Regeleinrichtung zuführbar sind. Häufig sind derartige bürstenlose Motoren mit Hallsensoren ausgeführt kommerziell erhältlich.In a further advantageous embodiment of the invention, it is provided that the drive unit comprises a brushless DC motor and the measurement of the position and / or speed and / or speed and / or acceleration of the movable drawer directly via the commutator signal, wherein the thus obtained Signals of the control device can be fed. Frequently, such brushless motors with Hall sensors are commercially available.
Heutzutage sind bereits elektrische Motoren in Kleinstbauweise erhältlich, bei denen eine elektronische, optische oder magnetische Positionsmesseinrichtung bereits im elektrischen Motor integriert ist, was sowohl Platz als auch Zeit beim Einbau spart.Nowadays, micro-electric motors are already available in which an electronic, optical or magnetic position-measuring device is already integrated in the electric motor, which saves both space and time during installation.
Die vorliegende Erfindung betrifft weiters ein Verfahren zum Bewegen einer in oder an einer Anordnung gelagerten bewegbaren Schublade, insbesondere Schublade, durch eine Antriebseinheit, insbesondere elektrischer Motor, wobei die Anordnung einen Antriebeinheitsregler und eine Positionsmesseinrichtung aufweist, dadurch gekennzeichnet, dass die Positionsmesseinrichtung dem Antriebeinheitsregler Signale zusendet und der Antriebeinheitsregler in Abhängigkeit von diesen Signalen der Antriebseinheit den Befehl zur Beschleunigung der bewegbaren Schublade gibt.The present invention further relates to a method for moving a movable drawer, in particular a drawer, mounted in or on an arrangement by a drive unit, in particular an electric motor, the arrangement having a drive unit controller and a position-measuring device, characterized in that the position-measuring device sends signals to the drive unit controller and the drive unit controller issues the command to accelerate the movable drawer in response to these drive unit signals.
Die Positionsmesseinrichtung stellt dabei, wie bereits ausgeführt, eine besonders einfache Realisierung der Beschleunigungsmesseinrichtung dar.As already mentioned, the position-measuring device represents a particularly simple realization of the acceleration measuring device.
Beispielsweise kann vorgesehen sein, dass die Positionsmesseinrichtung bei einer extern verursachten Änderung des Bewegungszustandes der bewegbaren Schublade ein Signal an den Antriebeinheitsregier sendet und dieser der Antriebseinheit den Befehl zur Beschleunigung der bewegbaren Schublade gibt. Unter Änderung des Bewegungszustandes ist natürlich - wie in der Physik üblich - sowohl das Anfahren der bewegbaren Schublade als auch eine Änderung der Geschwindigkeit einer eine gleichförmige Bewegung ausführenden bewegbaren Schublade zu verstehen.For example, it can be provided that the position-measuring device transmits a signal to the Antriebseinheitsregier at an externally caused change in the state of movement of the movable drawer and this gives the drive unit the command to accelerate the movable drawer. Under changing the state of motion is of course - as usual in physics - both the start of the movable drawer and a change in the speed of a uniform movement exporting movable drawer to understand.
Es kann aber auch vorgesehen sein, dass die Positionsmesseinrichtung nach der Bewegung der bewegbaren Schublade über eine vorgebbare bzw. vorgegebene Strecke ein Signal an den Antriebeinheitsregler sendet und dieser der Antriebseinheit den Befehl zur Beschleunigung der bewegbaren Schublade gibt. Hierbei handelt es sich also um eine reine Wegmessung. Die Antriebseinheit wird aktiviert, sobald die bewegbare Schublade die vorgegebene Strecke zurückgelegt hat. Die Zeit, die es dafür benötigt, spielt keine Rolle.But it can also be provided that the position measuring device sends a signal to the drive unit controller after the movement of the movable drawer over a predetermined or predetermined distance and this gives the drive unit the command to accelerate the movable drawer. This is therefore a pure distance measurement. The drive unit is activated as soon as the movable drawer has covered the specified distance. The time it takes for this does not matter.
Bei diesem Auslösungsverfahren kann vorteilhafterweise weiters vorgesehen sein, dass die von der bewegbaren Schublade zurückzulegende Strecke, nach der die Positionsmesseinrichtung ein Signal an den Antriebeinheitsregler abgibt, je nach Bewegungsrichtung der bewegbaren Schublade unterschiedlich einstellbar bzw. eingestellt ist. Beispielsweise könnte als Aktivierungsweg zur Auslösung einer vom Möbelkorpus weg gerichteten Bewegung ein Weg von 1 Millimeter gewählt werden, während die Auslösung einer zum Möbelkorpus hin gerichteten Bewegung nach einem Weg von 10 Millimetern erfolgt.In this triggering method can advantageously be further provided that the distance to be traveled by the movable drawer, after which the position measuring device outputs a signal to the drive unit controller, depending on the direction of movement of the movable drawer is set or adjusted differently. For example, a path of 1 millimeter could be chosen as the activation path for triggering a movement directed away from the furniture body, while the triggering of a movement directed towards the furniture carcass takes place after a distance of 10 millimeters.
