Description
Die vorliegende Erfindung betrifft eine Ringspinnmaschine, die eine bewegte Ringbank und mindestens einen an der Ringbank angeordneten und einer Arbeitsstelle der Ringspinnmaschine zugeordneten Sensor zur Überwachung eines Fadens aufweist.
Die Ringspinnmaschine umfasst ferner eine Führungseinrichtung mit einem ersten und einem zweiten Führungsmittel zum Heben und Senken der Ringbank. Das erste Führungsmittel ist ortsfest an der Ringspinnmaschine angeordnet und das zweite Führungsmittel ist mit der Ringbank verbunden und bewegt sich beim Heben und Senken der Ringbank relativ zum ersten Führungsmittel. Die vorliegende Erfindung betrifft außerdem ein Verfahren zum Betreiben des Sensors.The present invention relates to a ring spinning machine, which has a moving ring rail and at least one arranged on the ring rail and a workstation of the ring spinning machine associated sensor for monitoring a thread.
The ring spinning machine further comprises a guide device with a first and a second guide means for raising and lowering the ring rail. The first guide means is fixedly arranged on the ring spinning machine and the second guide means is connected to the ring rail and moves when lifting and lowering the ring rail relative to the first guide means. The present invention also relates to a method of operating the sensor.
Die
Wie bereits erwähnt, werden die Signale der Sensoren an eine übergeordnete Steuerung oder Auswerteeinheit weitergegeben. Außerdem müssen die Sensoren mit elektrischer Energie versorgt werden. Dazu ist es erforderlich, Leitungen von der bewegten Ringbank zu den feststehenden Teilen der Maschine zu führen. Die ständige Bewegung stellt eine hohe Beanspruchung für die Leitungen dar. Dies kann letztlich zu einer Schädigung der Leitungen führen.As already mentioned, the signals from the sensors are forwarded to a higher-level control or evaluation unit. In addition, the sensors must be supplied with electrical energy. For this purpose, it is necessary to lead lines from the moving ring rail to the fixed parts of the machine. The constant movement represents a high stress on the lines. This can ultimately lead to damage to the lines.
Es ist daher eine Aufgabe der vorliegenden Erfindung, die elektrische Anbindung des mindestens einen an der bewegten Ringbank angeordneten Sensors an die Ringspinnmaschine zu verbessern.It is therefore an object of the present invention to improve the electrical connection of the at least one arranged on the moving ring rail sensor to the ring spinning machine.
Zur Lösung der Aufgabe wird an dem ersten Führungsmittel eine erste Spule angeordnet, an dem zweiten Führungsmittel ist eine zweite Spule angeordnet, es sind Mittel zur induktiven Übertragung von elektrischer Energie und/oder Daten zwischen der ersten und zweiten Spule vorhanden und der mindestens eine Sensor ist mit der zweiten Spule verbunden.To solve the problem, a first coil is arranged on the first guide means, on the second guide means, a second coil is arranged, there are means for inductive transmission of electrical energy and / or data between the first and second coil and the at least one sensor connected to the second coil.
Durch die Anordnung der beiden Spulen an den Führungsmitteln der Führungseinrichtung der Ringbank kann zwischen den Spulen ein geringer Abstand realisiert werden, so dass eine induktive Übertragung von Energie und Daten leicht realisiert werden kann. Die induktive Übertragung ermöglicht den Verzicht auf bewegte Leitungen und verbessert somit die elektrische Anbindung des mindestens einen an der Ringbank angeordneten Sensors.The arrangement of the two coils on the guide means of the guide device of the ring rail, a small distance can be realized between the coils, so that an inductive transmission of energy and data can be easily realized. The inductive transmission makes it possible to dispense with moving lines and thus improves the electrical connection of the at least one sensor arranged on the ring rail.
Gemäß einer möglichen Ausführung der vorliegenden Erfindung ist eines der beiden Führungsmittel als längeres Führungsmittel und das andere der beiden Führungsmittel als kürzeres Führungsmittel ausgebildet, wobei das kürzere Führungsmittel zum Heben und Senken der Ringbank relativ zum längeren Führungsmittel in Richtung der Längsausdehnung des längeren Führungsmittels bewegt wird. Für diese Ausführungsform gibt es prinzipiell zwei verschiedene Ausführungsmöglichkeiten.According to a possible embodiment of the present invention, one of the two guide means is formed as a longer guide means and the other of the two guide means as a shorter guide means, wherein the shorter guide means for raising and lowering the ring rail is moved relative to the longer guide means in the direction of the longitudinal extent of the longer guide means. In principle, there are two different possible embodiments for this embodiment.
Das erste Führungsmittel kann als längeres Führungsmittel ausgebildet sein und das zweite Führungsmittel dementsprechend als kürzeres Führungsmittel. Das heißt, das längere Führungsmittel ist bei dieser Ausführung ortsfest an der Ringspinnmaschine angeordnet und das kürzere Führungsmittel ist mit der Ringbank verbunden.The first guide means may be formed as a longer guide means and the second guide means accordingly as a shorter guide means. That is, the longer guide means is fixedly arranged on the ring spinning machine in this embodiment, and the shorter guide means is connected to the ring rail.
Alternativ ist das erste Führungsmittel als kürzeres Führungsmittel ausgebildet und das zweite Führungsmittel ist als längeres Führungsmittel ausgebildet. Das heißt, das kürzere Führungsmittel ist bei dieser Ausführung ortsfest an der Ringspinnmaschine angeordnet und das längere Führungsmittel ist mit der Ringbank verbunden.Alternatively, the first guide means is designed as a shorter guide means and the second guide means is designed as a longer guide means. That is, the shorter guide means is fixedly arranged in this embodiment on the ring spinning machine and the longer guide means is connected to the ring rail.
Vorzugsweise erstreckt sich die Spule, die an dem längeren Führungsmittel angeordnet ist, über den Bewegungsbereich des kürzeren Führungsmittels. Dadurch wird erreicht, dass der Abstand der beiden Spulen während der gesamten Hubbewegung gering bleibt. Ein möglichst geringer Abstand vereinfacht die induktive Übertragung.Preferably, the spool located on the longer guide means extends over the range of movement of the shorter guide means. This ensures that the distance between the two coils during the entire stroke remains low. The smallest possible distance simplifies inductive transmission.
Um induktiv elektrische Energie und/oder Daten zwischen der ersten und zweiten Spule zu übertragen, ist die erste Spule vorzugweise mit einer Speiseeinrichtung verbunden, die zur Erzeugung eines hochfrequenten elektromagnetischen Wechselfeldes ausgebildet ist.In order to transmit inductively electrical energy and / or data between the first and second coil, the first coil is preferably connected to a feed device which is designed to generate a high-frequency alternating electromagnetic field.
Gemäß einer vorteilhaften Ausführungsform ist die erste Spule mit einem ersten Modulationsmittel verbunden, das das hochfrequente elektromagnetische Wechselfeld zur Übertragung von Daten moduliert und/oder demoduliert, und die zweite Spule ist mit einem zweiten Modulationsmittel verbunden, das das hochfrequente elektromagnetische Signal zur Übertragung von Daten moduliert und/oder demoduliert.According to an advantageous embodiment, the first coil is connected to a first modulation means which modulates and / or demodulates the high-frequency alternating electromagnetic field for transmitting data, and the second coil is connected to a second modulation means which modulates the high-frequency electromagnetic signal for the transmission of data and / or demodulated.
Vorzugsweise wird das hochfrequente elektromagnetische Wechselfeld zur Übertragung von Daten des Sensors zu einer übergeordneten Steuerung mittels des zweiten Modulationsmittels moduliert und mittels des ersten Modulationsmittels wieder demoduliert. Die Modulation des Wechselfeldes kann dabei beispielsweise durch Feldschwächung erfolgen. Umgekehrt ist es aber auch möglich, Daten von einer übergeordneten Steuerung zu dem Sensor zu übertragen, indem das hochfrequente elektromagnetische Wechselfeld mittels des ersten Modulators moduliert und mittels des zweiten Modulators demoduliert wird.Preferably, the high-frequency electromagnetic alternating field is modulated for transmitting data from the sensor to a higher-level controller by means of the second modulation means and demodulated again by means of the first modulation means. The modulation of the alternating field can be done for example by field weakening. Conversely, it is also possible to transmit data from a higher-level controller to the sensor by modulating the high-frequency alternating electromagnetic field by means of the first modulator and demodulating it by means of the second modulator.
Das längere Führungsmittel kann als Stange und das kürzere Führungsmittel als die Stange umgebende Hülse ausgebildet sein. Es besteht die Möglichkeit, die Stange ortsfest an der Ringpinnmaschine anzuordnen und die Hülse mit der Ringbank zu verbinden. Die Hülse wird dann beim Heben und Senken der Ringbank entlang der Stange bewegt. Alternativ ist es möglich, die Hülse ortsfest an der Ringspinnmaschine anzuordnen und die Stange mit der Ringbank zu verbinden. Beim Heben und Senken der Ringbank bewegt sich dann die Stange in der Hülse.The longer guide means may be formed as a rod and the shorter guide means as the sleeve surrounding the rod.

Die Windungen der Zylinderspule können dann um die Mantelfläche der Stange gewickelt sein. Alternativ kann die Stange auf der Mantelfläche eine spiralförmige Nut aufweisen, in die die Windungen der Zylinderspule eingelegt sind. Bei letzterer Ausführung ist die Spule besser geschützt vor mechanischen Einwirkungen bei der relativen Bewegung von Stange und Hülse, und die Anordnung weist eine bessere Stabilität auf.According to a particularly advantageous embodiment, the coil, which is arranged on the rod, formed as a cylindrical coil and arranged concentrically about the axis of the rod. The turns of the cylindrical coil can then be wound around the lateral surface of the rod. Alternatively, the rod on the lateral surface may have a spiral groove, in which the turns of the cylindrical coil are inserted. In the latter embodiment, the coil is better protected against mechanical effects of the relative movement of the rod and sleeve, and the arrangement has better stability.
In beiden Fällen können die Windungen der Zylinderspule vergossen werden und die äußere Mantelfläche der Zylinderspule kann eine Teflonbeschichtung aufweisen. Auch auf diese Weise wird die Spule bei der relativen Bewegung von Stange und Hülse geschützt.In both cases, the turns of the cylindrical coil can be cast and the outer surface of the cylindrical coil can have a Teflon coating. Also in this way, the coil is protected in the relative movement of the rod and sleeve.
