Description

Die Erfindung betrifft eine Liefervorrichtung für laufende Fäden gemäß Gattungsbegriff des Hauptanspruches.The invention relates to a delivery device for running threads according to the preamble of the main claim.

Bei den bekannten Lösungen dieser Art, teilweise auch genannt "Schußfadenspeicher", besteht die Bremsvorrichtung vielfach aus einem Kunststoffring mit einzelnen Fingern, die unter elastischer Vorspannung auf der Trommel anliegen (DE-AS 19 00 619). Beim Abzug des zwischen Ring und Fadenspeichertrommel verlaufenden Fadens wird die Fadenspannung auf einen gleichmäßigen aus dem Anlagedruck der Finger resultierenden Wert gebracht und jeder Finger wird von der Fadenspeichertrommelmantelfläche beim Durchzug des Fadens unter dem Finger hinweg abgehoben, um danach wieder in die Anlagestellung zur Trommel zu treten. Ähnliches hat man auch schon gemacht derart, daß die Finger kammartig von hintereinanderliegenden Ringen ausgehen (DE-OS 25 55 802) und vor allem auch nachstellbar sind hinsichtlich des Anlagedruckes zur Fadenspeichertrommel (EP-OS 340 897). Eingesetzt werden solche Schußfadenspeicher jüngst auch häufig an sogenannten "Düsen-Webmaschinen" (EP-OS 246 182). Diese tragen eine vorbestimmte abgezogene Länge des Fadens als Schußfaden in das Webfach ein. Zur Qualität des Gewebes und vor allem auch zur Minimierung des Schußfadenverlustanteiles ist man dabei bestrebt, die notwendige Länge des abgeschnittenen Schußfadens relativ genau einstellen zu können auf die vom jeweiligen Webfach vorbestimmte Sollänge. Bei der vorbekannten Lösung gemäß der erwähnten EP-OS 246 182 ist man deshalb den Weg gegangen, die Bremskraft der Finger soweit zu steigern, daß bei Bremsstellung kein Abziehen des Fadens mehr erfolgt, andererseits die gesamte Fadenliefervorrichtung der Webmaschine so zuzuordnen, daß eine Abfragung durch Fadensensoren an demjenigen Ende des Webfaches erfolgt, welches der Fadenliefervorrichtung gegenüberliegt. Dies ist aufwendig und verungleichmäßigt schon wegen der Verzögerungszeiten die Abzugsspannung des Fadens. Letzteres beeinträchtigt wiederum die Qualität des Gewebes.In the known solutions of this type, sometimes also called "weft thread storage", the braking device often consists of a plastic ring with individual fingers which rest under elastic tension on the drum (DE-AS 19 00 619). When the thread running between the ring and the thread storage drum is pulled off, the thread tension is brought to a uniform value resulting from the contact pressure of the fingers and each finger is lifted off the surface of the thread storage drum when the thread is pulled under the finger, in order to then return to the contact position with the drum . Similar things have already been done in such a way that the fingers come out like a comb from successive rings (DE-OS 25 55 802) and, above all, can also be adjusted with regard to the contact pressure to the thread storage drum (EP-OS 340 897). Recently, such weft thread stores have also frequently been used on so-called “jet weaving machines” (EP-OS 246 182). These enter a predetermined drawn-off length of the thread as a weft thread in the shed. For the quality of the fabric and, above all, for minimizing the proportion of weft loss, the aim is to be able to set the necessary length of the cut weft relatively precisely to the desired length predetermined by the respective shed. In the previously known solution according to the mentioned EP-OS 246 182, therefore, the way has been taken to increase the braking force of the fingers to such an extent that the thread is no longer pulled off when the brake is in position, and on the other hand to assign the entire thread delivery device to the weaving machine in such a way that it is sensed by Thread sensors take place at that end of the shed which is opposite the thread delivery device. This is complex and uneven even because of the delay times the take-up tension of the thread. The latter in turn affects the quality of the fabric.

Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Liefervorrichtung so auszugestalten, daß in einfachster aber optimaler Weise die Genauigkeit der Länge des abgezogenen Fadens bestimmt werden kann, insbesondere um eine möglichst genaue abzuschneidende Fadenlänge zum Eintrag in das Webfach insbesondere einer DüsenWebmaschine zu erhalten.The object of the present invention is to design a generic delivery device in such a way that the accuracy of the length of the drawn-off thread can be determined in a simple but optimal manner, in particular in order to obtain a thread length that is as precise as possible to be cut in the shed, in particular a jet loom.

Gelöst ist dies durch die im Kennzeichen des Hauptanspruches angegebene Erfindung. Die Unteransprüche stellen vorteilhafte Weiterbildungen dar.This is solved by the invention specified in the characterizing part of the main claim. The subclaims represent advantageous developments.

Zufolge dieser Ausgestaltung ist eine Fadenliefervorrichtung geschaffen, die in optimaler Weise insbesondere einem Düsenwebstuhl zugeordnet werden kann, weil es ermöglicht ist, die Länge des abgezogenen Fadens auf einen solchen Genauigkeitsgrad zu bestimmen, der dem Umfangsabstand zweier benachbarter schaltender Finger entspricht. Wegen der Vielzahl der Finger kann dieser Umfangsabstand außerordentlich klein, die Länge des abgeschnittenen Fadens also außerordnetlich genau bestimmt sein. Die Bewegung jedes Fingers der Bremsvorrichtung wird zur Erzeugung eines Schaltimpulses ausgenutzt. Dieser wird einer Meßvorrichtung zugeleitet. Durch Addition der Schaltimpulse ergibt sich ein Wert, der in direktem Proportionalverhältnis steht zur Länge des abgezogenen Fadens, begründet aus dem Umfangsrichtungs-Abstand zweier schaltender Finger. Als bedeutend hat sich dabei herausgestellt, daß bei einer etwaigen Nachstellbarkeit der Bremskraft selbst insofern eine direkte Abhängigkeit berücksichtigt werden kann zwischen abgezogener Fadenlänge und Fadenabzugsspannung.As a result of this configuration, a thread delivery device is created, which can be optimally assigned to a jet loom in particular, because it makes it possible to determine the length of the thread drawn off to such a degree of accuracy that corresponds to the circumferential distance between two adjacent switching fingers. Because of the large number of fingers, this circumferential distance can be extremely small, so the length of the cut thread can be determined with extraordinary precision. The movement of each finger of the braking device is used to generate a switching pulse. This is fed to a measuring device. Adding the switching impulses results in a value that is directly proportional to the length of the thread being drawn, based on the circumferential direction distance between two switching fingers. It has been found to be important that if the braking force can be readjusted, a direct dependency can be taken into account even between the thread length drawn off and the thread take-up tension.

Der Gegenstand der Erfindung ist auf den beiliegenden Zeichnungen in einem Ausführungsbeispiel dargestellt. Es zeigen:

  • Fig. 1 eine schematische Darstellung der Liefervorrichtung, zugeordnet zum skizzenmäßigen Webfach einer Düsenwebmaschine,
  • Fig. 2 die Liefervorrichtung teilweise im Schnitt dargestellt.
The object of the invention is illustrated in the accompanying drawings in one embodiment. Show it:
  • 1 is a schematic representation of the delivery device, assigned to the sketchy shed of a jet loom,
  • Fig. 2 shows the delivery device partially in section.

Die im Querschnitt kreisförmig gestaltete Fadenspeichertrommel 1 besitzt rückwärtig der zylindrischen Mantelfläche 1' die kegelstumpfförmige Auflauffläche 1". Vor dieser bewegt sich die Fadenführungsöse 2. Durch Relativdrehung der Fadenführungsöse 2 zur Fadenspeichertrommel 1 läuft der Faden F im Bereich der kegelstumpfförmigen Fläche 1" zu. Er zwängt sich in die Winkelkehle 3 ein und schiebt dadurch die jeweils vorher aufgewickelten Fadenlagen dicht an dicht liegend in Richtung des Kopfendes 4 der Fadenspeichertrommel 1.The thread storage drum 1, which is circular in cross section, has the frustoconical run-up surface 1 "behind the cylindrical outer surface 1 '. The thread guide eyelet 2 moves in front of this. The thread F runs in the region of the frustoconical surface 1" by relative rotation of the thread guide eyelet 2 to the thread storage drum 1. It squeezes into the angular groove 3 and thereby pushes the previously wound thread layers close together in the direction of the head end 4 of the thread storage drum 1.

Über das Kopfende 4 vorstehend erstrecken sich die von der Fadenspeichertrommel 1 ausgehenden einzelnen Finger 5. Diese sitzen elektrisch isoliert an einem Isolieraufsatz 6 der Fadenspeichertrommel 1. Sie sind elastisch ausgebildet. Sie legen sich unter federnder Vorspannung, gerichtet in Richtung des Pfeiles x gegen den Ring 7 an. Dieser Ring 7 ist an seiner Unterseite 7' ballig gestaltet. Der Faden F wird durch das Innere des Ringes 7 überkopf von der Fadenspeichertrommel abgezogen, vorzugsweise durch eine Festöse 8 hindurch. Bei diesem Abzug schlupft der Faden jeweils zwischen Ring 7 und Zunge 5 hindurch und hebt die Zunge 5 von der Anlage am Ring 7 ab. Dieses Abheben wird als Kontaktimpuls registriert dadurch, daß von vielen oder allen Zungen 5 je eine Leitung L + wegführt, die innerhalb einer nicht dargestellten Meßvorrichtung einen Stromkreis schließt zu dem am Gegenpol L - liegenden Ring 7.The individual fingers 5 extending from the thread storage drum 1 extend above the head end 4. These sit electrically insulated on an insulating attachment 6 of the thread storage drum 1. They are designed to be elastic. They lay under spring tension, directed in the direction of arrow x against ring 7. This ring 7 is crowned on its underside 7 '. The thread F is pulled overhead from the thread storage drum through the interior of the ring 7, preferably through a fixed eyelet 8. During this withdrawal, the thread slips between ring 7 and tongue 5 and lifts tongue 5 from the contact with ring 7. This lifting is registered as a contact impulse in that a line L + leads away from many or all tongues 5 and closes a circuit within a measuring device (not shown) to the ring 7 on the opposite pole L -.

Die Auswärtsfederung der Finger 5 ist begrenzt durch die Isolierschulter 9 eines Ringkragens 10. Dieser sitzt an den freien Enden der Wand 11 eines Topfes 12, welcher der Fadenspeichertrommel 1 zugeordnet ist. Die Finger 5 sind dabei in ihrer Grundstellung zum freien Ende hin zulaufend leicht konisch ausgerichtet. Sie können anstelle der geradlinigen Erstreckung gemäß Fig. 2 auch leicht schräg gerichtet verlaufen, vorzugsweise entsprechend dem Wandern des Fadenabzugspunktes unter dem Ring 7 hindurch.The outward suspension of the fingers 5 is limited by the insulating shoulder 9 of an annular collar 10. This is located at the free ends of the wall 11 of a pot 12, which is assigned to the thread storage drum 1. The fingers 5 are slightly tapered in their basic position towards the free end. Instead of the straight extension according to FIG. 2, they can also run slightly obliquely, preferably correspondingly the migration of the thread take-off point under the ring 7.

Der Ring 7 sitzt an einem Träger 13 und ist auf diesem längsverschieblich. Durch die Längsverschiebungs-Einstellung kann der wirksame freie Hebelarm H der Finger 5 variiert werden und damit auch die Anlagekraft in Richtung des Pfeiles x und somit darüber hinaus die Bremsung des Fadens beim Abzug.The ring 7 sits on a carrier 13 and is longitudinally displaceable thereon. Due to the longitudinal displacement setting, the effective free lever arm H of the fingers 5 can be varied and thus also the contact force in the direction of the arrow x and thus also the braking of the thread when the trigger is pulled.

Bei der Arbeitsweise der Liefervorrichtung wird der Faden F zunächst in Wickelbewegung, also durch tangentialen Zulauf auf die Fadenspeichertrommel gewickelt und dort gespeichert, bis eine vorgesehene Anzahl von Fadenwindungen vorliegt. Der Sender einer Lichtschranke 14 tastet dabei beispielsweise die Mantelfläche 1' ab. Wird der ihm gegenüberliegende Bereich der vorzugsweise spiegelnden Mantelfläche 1' von Fadenlagen überdeckt, so wird die weitere Fadenzufuhr gesperrt oder durch Verminderung der Aufwickelgeschwindigkeit reduziert. Erfolgt nun ein Abziehen, so wird diese Fläche wieder frei und eine entsprechende Schalteinrichtung steuert oder vergrößert den Fadenzulauf wieder. Während des Betriebes kann man durch Verschieben des Ringes 7 die optimale Fadenabzugsspannung einstellen. Nicht einmal diese Einstellhandhabung würde die Kontaktfunktion der Finger 5 unterbinden. Selbst während Verstellung des Ringes kann man also die angezogene Fadenlänge messen und darüber dann sogar eine integrierende Fadenlänge bekommen, in welche die Spannung schon eingerechnet ist. Auch kann man durch die Verstellung des Ringes 7 unterschiedlichen Fadenmaterialien, sogar bis zur Elastizität eines Fadens, Rechnung tragen.In the mode of operation of the delivery device, the thread F is first wound in a winding movement, that is to say by a tangential feed onto the thread storage drum and stored there until a predetermined number of thread windings is present. The transmitter of a light barrier 14 scans the lateral surface 1 ', for example. If the area of the preferably reflecting outer surface 1 'opposite it is covered by thread layers, the further thread supply is blocked or reduced by reducing the winding speed. If a pull-off now takes place, this area becomes free again and a corresponding switching device controls or increases the thread feed again. During operation, the optimum thread take-off tension can be set by moving the ring 7. Not even this adjustment handling would prevent the contact function of the fingers 5. Even while the ring is being adjusted, you can measure the thread length that has been tightened and then even get an integrating thread length into which the tension is already included. You can also take into account 7 different thread materials, even up to the elasticity of a thread, by adjusting the ring.

Sieht man die Finger 5 nicht an der Trommel vor, sondern beispielsweise am Ring und läßt sie, wie vorbekannt, elastisch auf der Trommelmantelfläche aufliegen, so braucht es sich bei der Fadenspeichertrommel 1 nicht, wie beim Ausführungsbeispiel, um eine still stehende Trommel zu handeln, sondern dann könnte sich zum tangentiaien Zuiauf des Fadens auch die Trommel 1 drehen, in welchem Falle die Fadenführungsöse 2, wie ebenfalls bekannt, still stünde.If the fingers 5 are not provided in front of the drum, but rather, for example, on the ring and, as previously known, they rest resiliently on the drum surface, the thread storage drum 1 does not need to be a stationary drum, as in the exemplary embodiment, but then the drum 1 could also rotate for the tangential feed of the thread, in which case the thread guide eyelet 2, as is also known, would stand still.

Die erfindungsgemäße Liefervorrichtung ist dem Webfach einer insbesondere im Düsenbetrieb mit einer Blasluftdüse (D) arbeitenden Webmaschine derart zugeordnet, daß der abgezogene Faden in das Webfach W eingetragen wird. Diese Webfachlänge bestimmt die Länge des Fadens, der unter vorbestimmter Spannung abgezogen werden muß, wobei nach Abzug dieser Länge durch eine in der Zeichnung symbolisch als Schere versinnbildlichte Schneidvorrichtung S, gesteuert von der Meßeinrichtung der Liefervorrichtung, ein Abschneiden erfolgt.The delivery device according to the invention is assigned to the shed of a weaving machine, in particular in the jet mode with a blown air nozzle (D), in such a way that the thread drawn off is inserted into the shed W. This shed length determines the length of the thread which has to be drawn off under a predetermined tension, after which this length is cut off by a cutting device S symbolized as scissors in the drawing, controlled by the measuring device of the delivery device.

Alle in der Beschreibung und in der Zeichnung dargestellten neuen Merkmale sind erfindungswesentlich, auch soweit sie in den Ansprüchen nicht ausdrücklich beansprucht sind.All new features shown in the description and in the drawing are essential to the invention, even if they are not expressly claimed in the claims.
