Description
Die vorliegende Erfindung betrifft eine Einrichtung zur Ueberwachung der Schussfäden an einer Rundwebmaschine, welche von der jeweiligen Spule der im Webfach entlang einer vom Rundriet gebildeten Kreisbahn umlaufenden Webschützen abgewickelt und an den Geweberand des erzeugten Schlauchgeweoes abgegeben werden, wobei Abtastmittel den jeweiligen Schussfaden überwachen, um bei einem Schussfadenfehler ein elektrisches Regelsignal zu erzeugen und mit einem vom abgezogenen Schußfaden gegen die Wirkung von federartigen Rückstellmitteln ausgelenkten Schwenkhebel.The present invention relates to a device for monitoring the weft threads on a circular loom, which of the respective coil of the Shed along a circular path formed by Rundriet Wrapped around and around delivered the fabric edge of the tube fabric produced be scanning means, the respective Monitor weft yarn to make a weft error to generate an electrical control signal and with one of the withdrawn weft against the effect deflected by spring-like return means Pivoting lever.
Es sind allgemein Rundwebmaschinen bekannt, bei welchen eine Mehrzahl Teilschäfte kreisförmig um das Rundriet der Maschine herum angeordnet sind und je eine Mehrzahl innere und äussere Weblitzen zur Führung jeweils eines Teils der zwei ringsumverteilten Kettfadenscharen tragen, denen zur Bildung des Web- bzw. Wanderfaches über die umlaufende Hauptwelle eine gegenläufige auf- und niedergehende Wechselbewegung erteilt wird. Die im Rundriet von der Hauptwelle umlaufend angetriebenen Webschützen tragen dabei den, von der betreffenden mitgeführten Spule abzuziehenden Schussfaden kontinuierlich in das Wanderfach ein. Das so erzeugte Schlauchgewebe wird dann abgezogen und flach zusammengelegt aufgewickelt.There are generally circular looms known in which a plurality of partial shanks circular the Rundriet the machine are arranged around and depending a plurality of inner and outer healds for guidance in each case a part of the two round-distributed Kettfadenscharen which contribute to the formation of the web or Wanderfaches about the main revolving wave one opposing up and down alternating movement is granted. The in Rundriet of the main shaft circulating driven weavers wear it the deducted from the relevant entrained coil Weft continuously in the walking compartment one. The tubular fabric thus produced is then peeled off and wound up folded flat.
Dabei ist es wesentlich, das ordnungsgemässe Vorhandensein der von den Spulen der umlaufenden Schützen abgezogenen Schussfäden sorgfältigst zu überwachen, um bei einem Schussfadenfehler, etwa durch Schussfadenbruch oder Erschöpfung der Schussfadenspule, die Maschine zur Vermeidung von Webfehler entsprechend ansteuern, beispielsweise sofort abstellen zu können.It is essential to the proper existence that of the coils of the revolving Carefully protect withdrawn weft threads monitor to get at a weft error, about by weft breakage or exhaustion of the Weft bobbin, the machine to avoid Actively control web errors, for example immediately to be able to turn off.
Bekannte Einrichtungen dieser Art verwenden hierfür u.a. photooptische Signalgeber, bei denen die Fotozelle durch eine in den Lichtstrahl einschwenkende Reflexfläche aktiviert wird. Diese Lichtschranken können aber den heutigen Anforderungen, insbesondere auch im Hinblick auf die wesentlich erhöhten Umlaufgeschwindigkeiten der Webschützen und die Erzeugung präziser Steuersignale, nicht mehr genügen. Lichtschranken sind dabei von je her anfällig auf Fremdlichteinwirkungen, verstauben schnell und lassen eine Verarbeitung von Reflexbändchen wegen "Erblinden" nicht zu.Known devices of this type use for this purpose et al Photo-optical signal transmitter in which the photocell by a reflection in the light beam reflecting surface is activated. These photocells can but today's requirements, especially in view of the significantly increased rotational speeds the web shooter and the generation precise control signals, not enough. light barriers are always susceptible to extraneous light effects, dust quickly and leave a processing of reflex ribbons because of "blindness" not to.
Die AT 387 797 offenbart einen Schußfadenwächter für eine Rundwebmaschine, bei der ein Reflektor auf einer durch den Schußfaden ausgelenkten Fadenführerstange angeordnet ist. Im normalen Betrieb befindet sich der Reflektor außerhalb des Strahlenwegs eines Lichtsenders. Reißt der Schußfaden, so bewegt sich die Fadenführerstange in eine Endlage, in der sich der Reflektor im Strahlenweg des Lichtsenders befindet und die Lichtstrahlen zu einem Lichtempfänger reflektiert, der daraufhin ein Signal abgibt, das zum Anhalten des Webstuhls führt.AT 387 797 discloses a weft detector for a circular loom with a reflector on a deflected by the weft thread guide rod is arranged.

If the weft tears, then the weft moves Thread guide rod in an end position, in which the reflector located in the beam path of the light emitter and reflects the light rays to a light receiver, which then emits a signal to stop the Loom leads.
Aus der CH-A-489 641 ist eine Vorrichtung bekannt, die ais Schußfadenwächter in einem Webstuhl verwendet werden kann, bestehend aus einem fixen Teil, in dem ein beweglicher Teil geführt wird, der in eine abwecnselnde Translationsbewegung versetzt werden kann. Auf dem fixen Teil ist ein Dauermagnet oder ein Elektromagnet, der durch Gleich- oder Wechselstrom gesbeist wird, vorgesehen der im Betrieb in einer Spule im beweglichen Teil eine Spannung induziert. Die Spule ist über einen Schalter mit einer weiteren Spule verbunden, die bei geschlossenem Schalter in einer vierten Spule am fixen Teil eine Spannung induziert, aus der erkannt werden kann, ob der Schalter geschlossen ist oder nicht. Der Schalter am beweglichen Teil kann in einem Webstuhl in Abhängigkeit eines gerissenen Fadens durch kapazitive oder induktive Kopplung angesteuert werden, wobei im letzteren Fall ein auf einem Fallbügel, der nur durch den durchlaufenden Schußfaden in gehobener Stellung gehalten wird, montierter Magnet den Schalter schließt, wenn der Fallbügel bei gerissenem Faden herunterfällt.From CH-A-489 641 a device is known, The ais weft keeper used in a loom can be made up of a fixed part, in where a moving part is led into a descent Translation movement to be offset can. On the fixed part is a permanent magnet or a Electromagnet powered by DC or AC is provided, provided in operation in a coil induces a voltage in the moving part. The sink is connected via a switch to another coil, with the switch closed in a fourth Coil on the fixed part induces a voltage from the It can be detected whether the switch is closed or not. The switch on the moving part can in a loom depending on a torn thread triggered by capacitive or inductive coupling be in the latter case, one on one Fall bar, the only through the continuous weft is held in a raised position, mounted Magnet closes the switch when the fall bar comes on torn thread falls down.
