Druckmittelzylinderanordnung mit Positionssensoren für die Positionserfassung der KolbenstellungPressure cylinder arrangement with position sensors for the position detection of the piston position
Die Erfindung betrifft eine Drackmittelzylinderanordnung mit Positionssensoren für die Positionserfassung der Kolbenstellung mit mindestens einem analogen Positionssensor, und mit mindestens einem Druckmittelzylinder, in dem ein axial geführter Kolben angeordnet ist, mit dem eine Kolbenstange koaxial verbunden ist, die durch einen mit Dichtungen versehenen Gehäusedeckel aus dem Zylindergehäuse hinausragt, und mit mindestens einem elektromagnetischen Ventil, das mit mindestens einer Signalleitung mit mindestens einem Programmiergerät verbunden ist, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a drainage medium cylinder arrangement with position sensors for the position detection of the piston position with at least one analog position sensor, and with at least one pressure medium cylinder, in which an axially guided piston is arranged, to which a piston rod is coaxially connected, which is provided by a seal provided with seals Housing cover protrudes from the cylinder housing, and with at least one electromagnetic valve, which is connected to at least one signal line with at least one programming device, according to the preamble of claim 1.
Aus der DE 198 27 765 C2 ist bereits eine derartige Positionserfassung der Kolbenstellung bekannt.One such is already known from DE 198 27 765 C2 Position detection of the piston position known.
Die D ckmittelzylinderanordnung mit Positionserfassung der Kolbenstellung in diesem Beispiel umfasst einen Sensor und eine Befestigung. Die Befestigung weist ein proximales Ende auf, das an einem Zylinderrohr anliegt, um die Position der Befestigung festzulegen. Das proximale Ende weist eine erste Befestigungsnut auf, in welche eine Zugstange eingesetzt ist, und erste Stellschrauben zum Befestigen der eingesetzten Zugstange an der Befestigung. Andererseits ist in dem Spitzenabschnitt eine zweite Befestigungsnut ausgebildet, und der Sensor kann in dieser Nut derart angebracht werden, dass die Position des Sensors in axialer Richtung des Zylinderrohres einstellbar ist. Die Befestigung kann in unabhängiger Weise in dem korrekten Winkel an der Zugstange angebracht werden, indem die Befestigung an der Zugstange befestigt wird, während der Spitzenabschnitt der Befestigung an dem Zylinderrohr anliegt. Damit kann der Sensor in unabhängiger Weise an der an der Zugstange fixiert werden, wodurch der Befestigungsvorgang vereinfacht wird. Außerdem kann der Sensor beim Ersatz oder zum Einstellen seiner Position in unabhängiger Weise installiert bzw. entfernt werden, ohne die Befestigung zu lösen, wodurch die Wartung vereinfacht wird.The medium cylinder arrangement with position detection of the piston position in this example comprises a sensor and a fastening. The attachment has a proximal end that abuts a cylinder barrel to determine the position of the attachment. The proximal end has a first fastening groove, into which a pull rod is inserted, and first set screws for fastening the inserted pull rod to the fastening. On the other hand, a second fastening groove is formed in the tip section, and the sensor can be mounted in this groove in such a way that the position of the sensor can be adjusted in the axial direction of the cylinder tube. The attachment can be independently attached to the tie rod at the correct angle by attaching the attachment to the tie rod while the tip portion of the attachment is against the cylinder barrel. This allows the sensor to be fixed independently on the pull rod, which simplifies the fastening process. In addition, when replacing or adjusting its position, the sensor can be installed or removed independently without loosening the attachment, which simplifies maintenance.
Der Sensor kann unter Nerwendung einer zweiten Stellschraube an einer beliebigen Position in der Befestigungsnut verankert werden. Die zweite Stellschraube und die ersten Stellschrauben für die Befestigung können in derselben Richtung vorgesehen sein, so dass sie von derselben Richtung unter Nerwendung eines Werkzeuges gedreht werden können. Diese Konfiguration vermeidet Arbeitsräume in zwei Richtungen, wodurch die oben beschriebenen Vorgänge unter Nerwendung des Werkzeugs zuverlässig auch bei kleinen Arbeitsräumen durchgeführt werden können. Die Befestigungsnut hat vorzugsweise einen Querschnitt aufweisen, der so geformt ist, dass sie Νuteribreite, während der Sensor eine Bereite aufweist, kleiner ist als die innere Νutbreite der Befestigungsvorrichtungsnut aber größer als die Νufbreite der Öffnung. Somit wird beim Drehen der zweiten Stellschraube, zur Herstellung des Reibschlusses zwischen der Spitze der Schraube und demΝutenboden der Befestigungsnut der Sensor von die Öffnung der Befestigungsnut gepresst, um eine feste Halterung herzustellen.The sensor can be anchored at any position in the mounting groove using a second set screw. The second set screw and the first set screws for attachment may be provided in the same direction so that they can be rotated from the same direction using a tool. This configuration avoids work spaces in two directions, whereby the operations described above can be reliably performed even in small work spaces using the tool. The fastening groove preferably has a cross section which is shaped such that it is uter-wide, while the sensor has a width, is smaller than the inner outer width of the fastening device groove but larger than the outer width of the opening. Thus, when the second adjusting screw is turned, the sensor is pressed from the opening of the fastening groove in order to produce the frictional connection between the tip of the screw and the bottom of the fastening groove, in order to produce a fixed holder.
Nachteilig ist bei der bekannten Druckmittelzylinderanordnung jedoch, dass ein Zugang für die Sensoreinstellung bei der Montage beachtet werden muss.A disadvantage of the known pressure medium cylinder arrangement, however, is that access for the sensor setting during assembly must be taken into account.
Bei Sensoreinstellungsarbeiten an der D clαnittelzylinderanordnung, die im Inneren einer Maschine eingebaut sind, bedeutet dies ein zusätzlicher Aufwand beim Ausbau und Wiedereinbau der Druckmittelzylinderanordnung.In the case of sensor adjustment work on the cylinder cylinder arrangement which is installed inside a machine, this means an additional outlay in the removal and reinstallation of the pressure cylinder arrangement.
Die Aufgäbe der Erfindung ist es daher, eine SensoreinstellungsmögUchkeit ohne die Notwendigkeit zum Zugang zu der Druckrrjjttelzylinderanordnung zu schaffen.It is therefore the object of the invention to provide a sensor adjustment facility without the need to access the printing cylinder assembly.
Die Aufgabe wird ausgehend von einer Druckmittelzylinderanordnung mit Positionssensoren für die Positionserfassung der Kolbenstellung gemäß dem Oberbegriff des Anspruchs 1 in Verbindung mit dessen kennzeichnenden Merkmalen gelöst. Die nachfolgenden Unteransprüche geben vorteilhafte Weiterbildungen der Erfindung wieder.The object is achieved on the basis of a pressure medium cylinder arrangement with position sensors for detecting the position of the piston position in accordance with the preamble of claim 1 in conjunction with its characterizing features. The following subclaims represent advantageous developments of the invention.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Positionssensor die Anschlagposition des Kolbens erfasst und über eine Signalleitung an ein Programmiergerät weiterleitet, das wiederum die aktuelle Anschlagposition des Kolbens in einen nicht flüchtigen Speicher des Positionssensors hineinspeichert.The object is achieved in that the position sensor detects the stop position of the piston and via a signal line to a programming device forwards, which in turn stores the current stop position of the piston in a non-volatile memory of the position sensor.
Diese Lösung hat den Vorteil, dass die Positionserfassung der Kolbenstellung über eine Ferneinstellung durchgeführt werden kann, welche einen direkten Zugang zur Dmckrnittelzylinderanordnung überflüssig macht und somit kann die aufwändige Aus- und Einbauarbeit der Drackmittelzylinderanordnung erspart bleiben.This solution has the advantage that the position detection of the piston position can be carried out via a remote setting, which makes direct access to the pressure cylinder arrangement superfluous, and thus the time-consuming removal and installation work of the pressure medium cylinder arrangement can be spared.
Weiterhin wird die Größe des Positionssensors durch den Einsatz eines EPROM's recht klein gehalten, so dass die Gesamtgröße der Positionserfassungsvorrichtung minimal ist.Furthermore, the size of the position sensor is kept quite small by the use of an EPROM, so that the overall size of the position detection device is minimal.
Ein Vorteil der Erfindung ist, dass auch ein mobiles Position-SET-Modul als Alternative zu einem ortsfesten Programmiergerät - das vorzugsweise eine SPS (speiche rograrnmierbare Steuerung) ist - zum Einsatz kommen kann. Hierbei fährt der Kolben zunächst in die gewünschte Position, wonach über einen Taster des Position-SET-Moduls diese Position übernommen wird.An advantage of the invention is that a mobile position SET module can also be used as an alternative to a stationary programming device - which is preferably a PLC (programmable logic controller). Here, the piston first moves to the desired position, after which this position is adopted via a button on the Position SET module.
Weitere die Erfindung verbessernde Maßnahmen gehen aus den Unteransprüchen hervor oder werden nachstehend gemeinsam mit der Beschreibung eines bevorzugten Ausführungsbeispiels der Erfindung anhand der Figuren näher dargestellt. Es zeigt:Further measures improving the invention emerge from the subclaims or are described in more detail below together with the description of a preferred exemplary embodiment of the invention with reference to the figures.
