Description

Die Erfindung bezieht sich auf eine Stellvorrichtung, insbesondere für einen Arbeitstisch, mit wenigstens einem Stelltrieb, dessen mit einem Drehschrittgeber ausgerüsteter elektrischer Antriebsmotor über ein Motorkabel an eine Steuereinrichtung ansteckbar ist, die eine Leistungsstufe für den Antriebsmotor und eine an den Drehschrittgeber angeschlossene Auswerteschaltung für den Stellweg des Stelltriebes mit einem Speicher für vorgegebene Stellwege umfaßt.The invention relates to an adjusting device, in particular for a work table, with at least one actuating drive, which is equipped with a rotary stepper electric drive motor via a motor cable to a control device can be plugged, which is a power stage for the drive motor and an encoder connected to the rotary encoder evaluation for the travel the actuator comprises a memory for predetermined travel.

Um bei verstellbaren Arbeitstischen Beschädigungen zu vermeiden, die durch ein Nichteinhalten vorgegebener Stellwege verursacht werden, werden Stellvorrichtungen eingesetzt, bei denen die Stellwege durch ein Abschalten der elektrischen Antriebsmotoren für die Stelltriebe begrenzt werden. Werden die maximal zulässigen Stellwege nicht durch Endschalter, sondern durch eine entsprechende Vorgabe maximaler Stellwege an die Steuereinrichtung für die Antriebsmotoren bestimmt, indem die jeweiligen Stellwege mit Hilfe eines den Antriebsmotoren zugehörigen Drehschrittgebers in einer angeschlossenen Auswerteschaltung ermittelt und mit den abgespeicherten maximalen Stellwegen verglichen werden, so muß zunächst die Wegerfassung über die Auswerteschaltung durch einen Steuerungsabgleich auf eine bestimmte Ausgangsstellung des Stelltriebes bezogen werden, die auch der Vorgabe der maximal zulässigen Stellwege zugrunde liegt. Dieser Bezug geht allerdings beim Auswechseln eines Antriebsmotors verloren, so daß mit einem Motorwechsel ein Steuerungsabgleich erforderlich wird. Da jedoch die Steuerungseinrichtung nicht zwischen einem Motorwechsel und einem bloßen Abstecken eines Motors oder einem Stromausfall unterscheiden kann, wird aus Sicherheitsgründen nach jeder Stromunterbrechung ein Steuerungsabgleich empfohlen werden.In order to avoid damage in adjustable work tables, which are caused by non-compliance with predetermined travel, actuators are used in which the travel is limited by switching off the electric drive motors for the actuators. If the maximum permissible travel paths are not determined by limit switches, but by a corresponding specification of maximum travel paths to the control device for the drive motors, by determining the respective travel paths with the aid of a rotary stepper associated with the drive motors in a connected evaluation circuit and comparing them with the stored maximum travel ranges must first the displacement detection via the evaluation circuit by a control adjustment to a certain initial position of the actuator are based, which is also the specification of the maximum permissible travel ranges based. However, this reference is lost when replacing a drive motor, so that with a motor change a control balance is required. However, since the controller is not between a change of engine and a mere staking a For reasons of safety, control balancing is recommended after each power interruption.

Zur wirtschaftlichen Herstellung eines aus einem Motor und einem Steuergerät bestehenden elektromechanischen Antriebs ist es bekannt ( DE 296 20 516 U1 ), im Steuergerät die auf unterschiedliche Bautypen des Motors bezogenen Motorkenndaten abzuspeichern und die Motoren mit einer Motorkennung in Form eines Widerstandes im Motorkabel zu versehen, so daß die den Bautypen entsprechenden Motorkenndaten dem jeweiligen Motor zugeordnet werden können. Obwohl mit dieser Maßnahme sich bei einem gleichbleibenden Steuergerät elektromechanische Antriebe mit Motoren unterschiedlichster Bauart in einfacher Weise zusammenstellen lassen, kann mit Hilfe eines solchen Antriebs keine Anregung dafür gegeben werden, wie ein Steuerungsabgleich für durchzuführende Stellwege vorgenommen werden soll.For the economical production of an existing of a motor and a control unit electromechanical drive, it is known ( DE 296 20 516 U1 ), in the control unit to store the engine characteristics related to different types of engine and to provide the engines with a motor identifier in the form of a resistor in the motor cable, so that the engine types corresponding to the types of construction can be assigned to the respective engine. Although this measure can be put together in a simple way with a constant control unit electromechanical drives with motors of different types, no suggestion can be given with the help of such a drive, as a control adjustment is to be made for traversing paths.

Der Erfindung liegt somit die Aufgabe zugrunde, eine Stellvorrichtung der eingangs geschilderten Art, insbesondere für einen Arbeitstisch, so auszugestalten, daß ein Steuerungsabgleich nur dann angezeigt wird, wenn er auch tatsächlich notwendig ist.The invention is therefore based on the object, an adjusting device of the type described above, in particular for a work table in such a way that a control balance is only displayed when it is actually necessary.

Die Erfindung löst die gestellte Aufgabe dadurch, daß das Motorkabel mit einem eine Motorkennung bildenden elektrischen Widerstand versehen ist, daß die Auswerteschaltung eine Meßstufe und einen Speicher für den bei einem Steuerungsabgleich gemessenen Widerstandswert für die Motorkennung aufweist und daß die Steuereinrichtung an eine über eine Vergleicherstufe für den jeweils gemessenen und den abgespeicherten Widerstandswert ansteuerbare Anzeigeeinrichtung für einen notwendigen Steuerungsabgleich angeschlossen ist.The invention solves the problem set by the fact that the motor cable is provided with a motor identifier forming electrical resistance, that the evaluation circuit has a measuring stage and a memory for the measured during a control balance resistance value for the engine identification and in that the control device to a via a comparator stage for the respectively measured and the stored resistance controllable display device is connected for a necessary control adjustment.

Da zufolge dieser Maßnahmen in einfacher Weise eine Motorkennung durch einen elektrischen Widerstand ermöglicht wird, dessen Widerstandswert über die Auswerteschaltung ohne weiteres erfaßt werden kann, kann durch einen Vergleich des jeweils erfaßten Widerstandswertes für die Motorkennung mit einem im Zuge des letzten Steuerungsabgleiches abgespeicherten Widerstandswert in vorteilhafter Weise ein allfälliger Motorwechsel erkannt und angezeigt werden, so daß der Steuerungsabgleich nur nach einem Motorwechsel, nicht aber nach einer bloßen Stromunterbrechung angezeigt wird. Umfaßt die Anzeigeeinrichtung eine Eingabeeinrichtung für einen Steuerungsabgleich, so kann der notwendige Steuerungsabgleich nach seiner Anzeige unmittelbar über die Eingabeeinrichtung durchgeführt werden.Since, according to these measures, a motor identification by an electrical resistance is made possible in a simple manner, the resistance value of which can be readily detected by the evaluation circuit, by comparing the respectively detected resistance value for the motor identification with one in the course of time the last control balance stored resistance value advantageously a possible engine change are detected and displayed, so that the control balance is displayed only after a motor change, but not after a mere power interruption. If the display device comprises an input device for a control adjustment, the necessary control adjustment can be carried out immediately after its display via the input device.

Die Motorkennung durch den hiefür vorgesehenen elektrischen Widerstand des Motorkabels kann außerdem zur Anpassung des Steuerprogramms für die Stellvorrichtung an unterschiedliche Arten von Antriebsmotoren genützt
werden. Zu diesem Zweck kann die Steuereinrichtung einen in Abhängigkeit vom gemessenen Widerstandswert des Motorkabels auslesbaren Programmspeicher für an unterschiedliche Arten von Antriebsmotoren angepaßte Steuerparameter, beispielsweise für Stellwege, aufweisen, so daß beim Einsatz einer entsprechenden Antriebsmotorart die Steuereinrichtung über die Motorkennung automatisch auf die für diese Antriebsmotorart vorgegebenen Steuerparameter abgestimmt werden kann, indem das der Motorkennung zugeordnete Steuerprogramm aus dem Programmspeicher in die Steuereinrichtung geladen wird. Damit wird es möglich, beispielsweise unterschiedliche Drehzahlen, Stellwege oder andere für eine Motorart charakteristische Steuerparameter automatisch steuerungstechnisch zu berücksichtigen.The engine identification by the provided therefor electrical resistance of the motor cable can also be used to adapt the control program for the actuator to different types of drive motors
become. For this purpose the control device can have a program memory which can be read out depending on the measured resistance of the motor cable for control parameters adapted to different types of drive motors, for example for travel paths, so that when a corresponding drive motor type is used, the control device automatically sets the control device via the motor code to the drive motor type Control parameter can be adjusted by the motor identifier associated control program is loaded from the program memory in the control device. This makes it possible to automatically take into account, for example, different speeds, travel ranges or other characteristic of an engine control parameters control technology.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt, und zwar wird eine erfindungsgemäße Stellvorrichtung für einen Arbeitstisch in einem vereinfachten Blockschaltbild gezeigt.In the drawing, the subject invention is illustrated, for example, and that a control device according to the invention for a work table is shown in a simplified block diagram.

Die dargestellte Stellvorrichtung weist einen Stelltrieb 1 beispielsweise zum Einstellen der Tischplatte eines Arbeitstisches der Höhe nach mit einem elektrischen Antriebsmotor 2 auf, der über ein Motorkabel 3 an eine Steuereinrichtung 4 angeschlossen ist, die zu diesem Zweck eine mehrpolige Steckaufnahme 5 für den Kabelstecker 6 besitzt. Die Steuereinrichtung 4 umfaßt eine über eine Versorgungsleitung 7 an ein Stromnetz anschließbare Leistungsstufe 8, die zur Steuerung des Antriebsmotors 2 über eine Steuerstufe 9 beaufschlagt wird. Diese Steuerstufe 9 kann in herkömmlicher Weise über einen Eingang 10 auch von Hand aus oder über eine Fernsteuerung bedient werden.The adjusting device shown has an actuating drive 1, for example, for adjusting the table top of a workbench in height with an electric drive motor 2, which is connected via a motor cable 3 to a control device 4, which has a multi-pin plug receptacle 5 for the cable connector 6 for this purpose. The control device 4 comprises a connectable via a supply line 7 to a power grid power stage 8, which is acted upon to control the drive motor 2 via a control stage 9. This control stage 9 can be operated in a conventional manner via an input 10 also by hand or via a remote control.

Der Antriebsmotor 2 ist mit einem Drehschrittgeber 11 ausgerüstet, dessen Ausgangssignale über das Motorkabel 3 an eine Auswerteschaltung 12 der Steuereinrichtung 4 übertragen werden. Diese Auswerteschaltung 12 erfaßt die jeweiligen Stellwege des Stelltriebes 1 mit Hilfe des Drehschrittgebers 11 des Antriebsmotors 2 und vergleicht sie in herkömmlicher Art mit vorgegebenen maximalen Stellwegen, die in einem Speicher 13 abgespeichert sind. Wird der jeweils abgespeicherte maximale Stellweg erreicht, so wird der Antriebsmotor 2 durch eine entsprechende Beaufschlagung der Leistungsstufe 8 über die Steuerstufe 9 abgeschaltet. Voraussetzung hiefür ist, daß der über den Drehschrittgeber 11 erfaßte Stellweg auf eine Ausgangslage des Stelltriebes 1 bezogen ist, auf der die im Speicher 13 abgespeicherten maximalen Stellwege beruhen. Diese Beziehung wird durch einen üblichen Steuerungsabgleich eingestellt und festgehalten.The drive motor 2 is equipped with a rotary incremental encoder 11 whose output signals are transmitted via the motor cable 3 to an evaluation circuit 12 of the control device 4. This evaluation circuit 12 detects the respective adjustment paths of the actuator 1 by means of the rotary incremental encoder 11 of the drive motor 2 and compares them in a conventional manner with predetermined maximum travel ranges, which are stored in a memory 13. If the respective stored maximum travel is reached, then the drive motor 2 switched off by a corresponding admission of the power level 8 via the control stage 9. Prerequisite for this is that the detected via the rotary incremental encoder 11 is related to a starting position of the actuator 1, based on the stored in the memory 13 maximum travel ranges. This relationship is set and recorded by a common control match.

Durch einen Motorwechsel geht die Bezugnahme des erfaßten Stellweges auf eine bestimmte Ausgangsstellung des Stelltriebes 1 jedoch verloren. Um einen solchen Motorwechsel anzeigen zu können, weist das Motorkabel 3 einen als Kennung für den jeweiligen Antriebsmotor 2 dienenden elektrischen Widerstand 14 auf, der über das Stromkabel 3 an eine Meßstufe 15 der Auswerteschaltung 12 angeschlossen wird. Mit einem Steuerungsabgleich wird der gemessene Wert des Widerstandes 14 als Kennung für den Antriebsmotor 2 in einen Speicher 16 eingelesen, der mit einer Vergleicherstufe 17 verbunden ist. Da diese Vergleicherstufe 17 auch an der Meßstufe 15 angeschlossen ist, kann mit Hilfe der Vergleicherstufe 17 überprüft werden, ob der jeweils gemessene Wert des Widerstandes 14 mit dem im Speicher 16 abgespeicherten Widerstandswert übereinstimmt. Stimmen die gemessenen und die abgespeicherten Widerstandswerte nicht überein, so bedeutet dies einen Motorwechsel, der über die Vergleicherstufe 17 und die Steuerstufe 9 in einer Anzeigeeinrichtung 18 angezeigt wird. Aufgrund dieser Anzeige ist ein Steuerungsabgleich vorzunehmen. Zu diesem Zweck kann die Anzeigeeinrichtung 18 eine Eingabeeinrichtung 19 umfassen, über die der Steuerungsabgleich vorgenommen werden kann, indem beispielsweise der Stelltrieb 1 auf die für die Bestimmung der maximalen Stellwege maßgebende Ausgangsstellung verfahren wird.By changing the engine reference of the detected travel is lost to a certain starting position of the actuator 1 but lost. In order to be able to indicate such a motor change, the motor cable 3 has an electrical resistor 14 serving as an identifier for the respective drive motor 2, which is connected via the power cable 3 to a measuring stage 15 of the evaluation circuit 12. With a control adjustment, the measured value of the resistor 14 is read as an identifier for the drive motor 2 in a memory 16 which is connected to a comparator stage 17. Since this comparator stage 17 is also connected to the measuring stage 15, it can be checked with the aid of the comparator stage 17 whether the respective measured value of the resistor 14 coincides with the resistance value stored in the memory 16. If the measured and the stored resistance values do not match, this means a motor change, which is displayed in a display device 18 via the comparator stage 17 and the control stage 9. Based on this display, a control adjustment is to be made. For this purpose, the display device 18 may include an input device 19, via which the control adjustment can be made, for example, by the actuator 1 is moved to the decisive for the determination of the maximum travel initial position.

Um die Steuereinrichtung 4 für unterschiedliche Arten von Antriebsmotoren 2 einstellen zu können, die beispielsweise unterschiedliche Stellwegvorgaben benötigen, kann die Steuerstufe 9 an einen Programmspeicher 20 für an unterschiedliche Arten von Antriebsmotoren 2 angepaßte Stellwege angeschlossen werden, so daß beim Einsatz einer bestimmten Motorart das für diese Motorart abgespeicherte Steuerprogramm aufgrund der erfaßten Motorkennung über den Widerstand 14 des Motorkabels 3 in die Steuerstufe 9 geladen und der Stellwegvorgabe zugrundegelegt werden kann, was gegebenenfalls das Ablegen geänderter Stellwegwerte in den Speicher 13 einschließt. Innerhalb einer Motorart bleibt dabei die Unterscheidung einzelner Antriebsmotoren über die Motorkennung erhalten. Selbstverständlich ist die Anpassung der Steuereinrichtung nicht auf unterschiedliche Stellwege beschränkt, sonder kann auch für andere Steuerparameter vorgenommen werden.In order to adjust the control device 4 for different types of drive motors 2, for example, require different Stellwegvorgaben, the control stage 9 can be connected to a program memory 20 adapted for different types of drive motors 2 travel ranges, so that when using a certain type of engine for this Motor type stored control program due to the detected engine ID can be loaded via the resistor 14 of the motor cable 3 in the control stage 9 and the Stellwegvorgabe can be based, which optionally includes the storage of changed Stellwegwerte in the memory 13. Within an engine type, the distinction between individual drive motors via the engine identification remains. Of course, the adjustment of the control device is not limited to different travel paths, but can also be made for other control parameters.
