Description

Die Erfindung betrifft eine Luftstrahlwebmaschine mit einer ausserhalb des Webfaches angeordneten Schussfaden­eintragsdüse und einer zwischen ihr und dem Webfach ange­ordneten Schussfadenablenkvorrichtung zum Fernhalten des Schussfadens vom Webfach nach Abgabe eines Signals zum Stillsetzen der Webmaschine infolge einer Störung.The invention relates to an air jet weaving machine with a weft insertion nozzle arranged outside the shed and a weft deflection device arranged between it and the shed for keeping the weft away from the shed after a signal is given to stop the loom as a result of a fault.

Bei einer Ablenkvorrichtung für den Schussfaden wird der Schussfaden pneumatisch oder mechanisch quer zu seiner normalen Laufrichtung in das Webfach seitlich abgelenkt und von einer Saugleitung aufgenommen. Derartige Vor­richtungen sind beispielsweise in der europäischen Patent­anmeldung 0 094 089 beschrieben. Bei Luftstrahlwebma­schinen befindet sich in der Regel auf der Austrittsseite des Schussfadens aus dem Webfach, also auf der der Ein­tragsdüse gegenüberliegenden Seite der Webmaschine, eine Absaugvorrichtung für die abgeschnittenen Enden der Schussfäden. Auf dieser Seite wird aus Platzgründen bei Luftstrahlwebmaschinen normalerweise auch ein Absaug­aggregat angeordnet. Um den Schussfaden von der Ablenk­vorrichtung zu einem Sammelbehälter beim Absaugaggregat zu befördern, ist in der Regel eine Schlauchleitung im Inneren der Webmaschine befestigt. Wenn solche Schlauch­leitungen auch beispielsweise an einem Längsträger des Gestells platzsparend montiert sind, können sie doch bei Reinigungs- oder Unterhaltsarbeiten hinderlich sein.In a deflection device for the weft thread, the weft thread is deflected laterally into the shed pneumatically or mechanically transversely to its normal running direction and is taken up by a suction line. Such devices are described for example in European patent application 0 094 089. In air jet weaving machines there is usually a suction device for the cut ends of the weft threads on the exit side of the weft thread from the shed, that is to say on the side of the weaving machine opposite the insertion nozzle. A suction unit is usually also arranged on this page for space reasons in air jet weaving machines. In order to convey the weft thread from the deflection device to a collecting container in the suction unit, a hose line is generally fastened inside the weaving machine. If such hose lines, for example, on a side member of the frame are mounted in a space-saving manner, as they can be a hindrance when cleaning or maintenance work.

Es ist Aufgabe der vorliegenden Erfindung, eine Trans­portleitung für den abgelenkten Schussfaden einer Luft­webmaschine längs durch die Maschine zu schaffen, die innerhalb der Webbreite der Maschine nicht in Erschei­nung tritt und somit auch bei Unterhaltsarbeiten nicht hinderlich sein kann.It is an object of the present invention to provide a transport line for the deflected weft thread of an air-jet weaving machine lengthways through the machine, which does not appear within the weaving width of the machine and therefore cannot be a hindrance even during maintenance work.

Die Erfindung besteht darin, dass innerhalb der Weblade eine Transportleitung für den abgelenkten Schussfaden untergebracht ist. Da der Schussfaden in Höhe der Ein­tragsdüse bzw. des Riets abgelenkt werden muss, ist es zweck­mässig, die Transportleitung gleich unterhalb des Rietprofils in das Ladenprofil zu legen, in welchem das Riet festge­klemmt ist. Die Herstellung eines solchen Rietprofils mit einem innenliegenden Kanal beispielsweise als Alu­minium bereitet keine Probleme. Ein Rietprofil mit einem innenliegenden geschlossenen Kanal kann zudem den Vorteil haben, dass seine Steifigkeit gegen Torsions- und Biege­deformationen im Vergleich zu einem offenen Rietprofil höher ist. Mit einer Transportleitung gemäss der Erfin­dung wird also einerseits eine separate Leitung einge­spart, andererseits kann die Weblade ohne zusätzliche Masse versteift werden.The invention consists in that a transport line for the deflected weft thread is accommodated within the sley. Since the weft thread must be deflected at the level of the entry nozzle or the reed, it is expedient to place the transport line directly below the reed profile in the shop profile in which the reed is clamped. The production of such a reed profile with an internal channel, for example as aluminum, poses no problems. A reed profile with an internal closed channel can also have the advantage that its stiffness against torsion and bending deformation is higher compared to an open reed profile. With a transport line according to the invention, a separate line is thus saved on the one hand, and on the other hand the sley can be stiffened without additional mass.

Anstatt im Rietprofil könnte der Schussfaden beispiels­weise auch in einer hohlen Antriebswelle der Weblade abgeführt werden.Instead of the reed profile, the weft thread could, for example, also be carried away in a hollow drive shaft of the sley.

Im folgenden wird die Erfindung anhand der Figuren näher beschrieben.

  • Fig. l gibt in einer perspektifischen Darstellung einen Ueberblick über die Ablenkvorrichtung für den Schussfaden und einen Teil einer Weblade mit der Transportleitung gemäss der Erfindung,
  • Fig. 2 zeigt einen schematischen Ueberblick über die Ablenkvorrichtung, die Transportleitung und die Entsorgungsstation für die abgeschnittenen Schuss­fäden,
  • Fig. 3 und 4 zeigen in Aufriss bzw. Grundriss und teil­weise geschnitten eine im Rietprofil integrierte Transportleitung für die abgelenkten Schussfäden.
The invention is described in more detail below with reference to the figures.
  • Fig. 1 gives a perspective view Overview of the deflection device for the weft thread and part of a sley with the transport line according to the invention,
  • 2 shows a schematic overview of the deflection device, the transport line and the disposal station for the cut weft threads,
  • 3 and 4 show in elevation or plan and partially cut a transport line integrated in the reed profile for the deflected weft threads.

In Fig. l ist ein Abschnitt der Weblade l0 in der Nähe der Hauptdüsen 6l bzw. 62 zu sehen. Die Ablenkvorrichtung für den Schussfaden umfasst die von oben auf den Weg des Schussfadens 5 gerichtete Blasdüse 7, den Trichter 23 im Rietprofil 2 und den Fadenführer 90. Im Rietprofil 2 ist das Riet l befestigt, mit dessen Führungskanal l2 der Schussfaden 5 während des Eintrages geführt wird. Der Führungskanal l2 befindet sich während des Schussein­trages in dem durch parallel zum Riet l gespannte Kett­fäden l3 und l4 gebildeten Webfach l5. Unterhalb des Riets ist im Rietprofil der Kanal 22, der als Transportleitung für den Schussfaden nach dem Ablenken dient. Das Rietprofil 2 ist über mehrere Hebel 3 an der Welle 4 der Weblade angeschraubt.A section of the sley 10 in the vicinity of the main nozzles 61 and 62 can be seen in FIG. The deflecting device for the weft thread comprises the blowing nozzle 7 directed from above onto the path of the weft thread 5, the funnel 23 in the reed profile 2 and the thread guide 90. The reed 1 is fastened in the reed profile 2, with the guide channel 12 of which the weft thread 5 is guided during the entry becomes. The guide channel l2 is located during the weft insertion in the shed l5 formed by warp threads l3 and l4 stretched parallel to the reed l. Below the reed is the channel 22 in the reed profile, which serves as a transport line for the weft after deflection. The reed profile 2 is screwed to the shaft 4 of the sley via several levers 3.

Es gibt bei einer Webmaschine verschiedene Arten von Störungen, sei es mechanischer, steuerungstechnischer oder textiltechnischer Art, bei welchen die Webmaschine angehalten werden muss. Da besonders Luftstrahlwebmaschi­nen mit verhältnismässig hoher Drehzahl, z.B. 600 Um­drehungen pro Minute, laufen, können sie nicht abrupt abgebremst werden. In der Regel gelingt es nicht, nach Auftreten einer Störung, die zum automatischen Abstellen einer Luftstrahlwebmaschine führt, die Maschine so schnell stillzusetzen, dass der nachfolgende Schusseintrag ver­hindert wird. Damit vor dem erneuten Starten der Webma­schine durch den Weber möglichst wenig Zeit aufgewandt werden muss, wird der vorbereitete Schuss nach Auftreten des Störungssignals zwar noch ausgelöst, gelangt aber dank des Zusammenwirkens von Blasdüse 7 und Trichter 23 nicht mehr in den Bereich des Riets l. Die jetzt eingeschaltete Blasdüse 7 lenkt die Spitze des Schussfadens 5 in Rich­tung auf die Eintrittsöffnung des Trichters 23, durch den Luft angesaugt wird. Die Saugluft strömt dann mit dem abgelenkten Schussfaden 5 durch den Hohlraum des End­stücks 24, in welchem zur Unterstützung der Saugwirkung am Eintritt in den Trichter 23 ein Injektor 25 angeordnet sein kann, der von der Leitung 26 mit Druckluft versorgt wird. Das Endstück 24 dient, wie in den Figuren 3 und 4 ersichtlich ist, einerseits zur Umlenkung des Fadens in eine Richtung parallel zur Längserstreckung des Rietpro­fils 2 und andererseits zur Abdichtung der Transportlei­tung 22. Auf der rechten Seite in Figur 3 bzw. 4 ist die Transportleitung 22 zum Empfangsstück 30 hin offen, in dessen Saugkanal 32 der abgelenkte Schussfaden 5 nochmals umgelenkt wird. Da das Rietprofil 2 mit dem Riet l und der ganzen Weblade hin- und herbewegt wird, muss die Eintrittsöffnung des Saugkanals 32 so gross gewählt wer­den, dass während des ganzen Bewegungsbereichs der Web­lade die Austrittsöffnung des Kanals 22 in jeder Bewe­gungsphase der Eintrittsöffnung des Saugkanals ohne Querschnittsverengung gegenübersteht. Am Rietprofil 2 muss ein Endstück 27 vorgesehen werden, welches den je­weils nicht vom Austrittsquerschnitt der Transportlei­tung 22 überdeckten Teil der Eintrittsöffnung in den Saugkanal 32 gegen die Umgebungsluft abschirmt. Eine Dichtung 3l zwischen dem Empfangsstück 30 und dem End­stück 27 verhindert das Ansaugen von Falschluft in diesem Bereich. Sie kann beispielsweise aus Plüsch angefertigt sein. In das Empfangsstück 30 kann auch ein Absaug­krümmer 36 gemäss Fig.2 einmünden, mit dem Teile des Schussfadens nach dem Eintrag von dieser Seite der Webla­de aufgenommen werden. Vom Empfangsstück 30 gelangt der abgelenkte Schussfaden durch die Saugleitung 37 in den Sammelbehälter 34, der schliesslich mit einem Gebläse 35 zur Erzeugung des Unterdrucks in den Saugleitungen 22 bis 37 verbunden ist.There are various types of malfunctions in a weaving machine, be it mechanical, control-related or textile-technical in which the weaving machine has to be stopped. Since air jet weaving machines in particular run at a relatively high speed, for example 600 revolutions per minute, they cannot be braked abruptly. As a rule, it does not succeed after Occurrence of a fault, which leads to the automatic shutdown of an air jet weaving machine, to shut the machine down so quickly that the subsequent weft insertion is prevented. So that the weaver has to spend as little time as possible before restarting the weaving machine, the prepared weft is still triggered after the fault signal occurs, but thanks to the interaction of the blowing nozzle 7 and the funnel 23, it no longer reaches the area of the reed 1. The blowing nozzle 7 now switched on directs the tip of the weft thread 5 in the direction of the inlet opening of the funnel 23, through which air is sucked in. The suction air then flows with the deflected weft thread 5 through the cavity of the end piece 24, in which an injector 25, which is supplied by the line 26 with compressed air, can be arranged to support the suction effect at the inlet into the funnel 23. The end piece 24 serves, as can be seen in FIGS. 3 and 4, on the one hand to deflect the thread in a direction parallel to the longitudinal extension of the reed profile 2 and on the other hand to seal the transport line 22. On the right side in FIGS. 3 and 4 is the transport line 22 open to the receiver 30, in whose suction channel 32 the deflected weft thread 5 is deflected again. Since the reed profile 2 is moved back and forth with the reed 1 and the entire sley, the inlet opening of the suction channel 32 must be selected to be large enough that the outlet opening of the channel 22 during the entire movement range of the sley in each movement phase of the inlet opening of the suction channel without narrowing the cross-section faces. An end piece 27 must be provided on the reed section 2, which ends into the part of the inlet opening that is not covered by the outlet cross section of the transport line 22 Shields suction channel 32 from the ambient air. A seal 3l between the receiver 30 and the end piece 27 prevents false air from being drawn in in this area. For example, it can be made of plush. A suction elbow 36 according to FIG. 2 can also open into the receiving piece 30, with which parts of the weft thread are picked up from this side of the sley after the entry. The deflected weft thread passes from the receiver piece 30 through the suction line 37 into the collecting container 34, which is finally connected to a blower 35 for generating the negative pressure in the suction lines 22 to 37.

In Fig. 2 ist ein schematischer Gesamtüberblick über die Ablenkvorrichtung, die Transportleitung und das nachge­schaltete Entsorgungssystem bestehend aus Sammelbehäl­ter 34 und Gebläse 35 gegeben. Zwischen der Hauptdüse 6l und dem Trichter 23 wird der Schussfaden 5 gegen das Ende des Ablenkvorganges über den Fadenführer 90 umge­lenkt, welcher sicherstellt, dass der Schussfaden in der vordersten Stellung der Weblade nach Drehung um Pfeil 4l in Fig. l in die Schere 8 eingeführt und abgeschnitten wird. In dieser Stellung befindet sich die Hauptdüse 6l, durch die der Schussfaden geliefert wird, zusammen mit der zweiten Hauptdüse 62 in der gestrichelten Position 6l′ bzw. 62′ nahe bei der Schere 8. Der Trichter 23 be­findet sich dabei in der Stellung 23′. Mit dem Abschnei­den des Schussfadens ist der Ablenkvorgang beendet.2 shows a schematic overall overview of the deflection device, the transport line and the downstream disposal system consisting of a collecting container 34 and a blower 35. Between the main nozzle 6l and the funnel 23, the weft 5 is deflected towards the end of the deflection process via the thread guide 90, which ensures that the weft thread is inserted into the scissors 8 in the foremost position of the sley after rotation by arrow 4l in FIG is cut off. In this position, the main nozzle 6l, through which the weft thread is supplied, together with the second main nozzle 62 in the dashed position 6l 'or 62' near the scissors 8. The funnel 23 is in the position 23 '. The deflection process ends when the weft thread is cut off.
