Description

Die Erfindung betrifft eine Vorrichtung zum Einführen des Fadens in den Fangschlitz einer leeren Spulenhülse gemäss Oberbegriff des Patentanspruches 1.The invention relates to a device for inserting the thread into the catch slot of an empty bobbin tube according to the preamble of claim 1.

Bei Spulenautomaten, an denen die Spulen auf einem drehbaren Re­volver gelagert sind, muss der zulaufende Faden ohne Unterbre­chung von der vollen Spule zum Fangschlitz einer leeren Hülse überführt und vom Fangschlitz erfasst werden, bevor eine Tren­nung des Fadens von der vollen Spule erfolgt. Der zulaufende Fa­den wird beim Spulvorgang vom Fadenführer direkt oder über die Treibwalze indirekt der Spulenoberfläche zugeleitet. Beim Wech­selvorgang, d.h. beim Drehen des Revolvers, gelangt die leere Spulenhülse in diesen Fadenlauf. Durch eine axiale Verschiebung des die Spulenhülse tragenden Spulendornes oder der vollen Packung wird bei herkömmlichen Spulautomaten der Fangschlitz auf der Spulenhülse in den Fadenlauf geführt, so dass der Faden im Fangschlitz eingeklemmt und von der leeren Spulenhülse mitgeris­sen wird. Gleichzeitig wird der Faden zwischen der neuen Hülse und der vollen Spule durchgetrennt.In automatic bobbins on which the bobbins are mounted on a rotating turret, the incoming thread must be transferred from the full bobbin to the catch slot of an empty tube without interruption and be caught by the catch slot before the thread is separated from the full bobbin. The incoming thread is fed directly to the bobbin surface by the thread guide or indirectly via the drive roller during the winding process. When changing, i.e. When turning the revolver, the empty bobbin tube gets into this thread run. By means of an axial displacement of the bobbin mandrel carrying the bobbin tube or the full pack, the catch slot on the bobbin tube is guided into the thread path in conventional automatic winding machines, so that the thread is clamped in the catch slot and entrained by the empty bobbin tube. At the same time, the thread between the new tube and the full bobbin is cut.

Diese bekannte Vorrichtung ermöglicht eine einwandfreie Faden­übernahme. Sie hat jedoch den Nachteil, dass insbesondere bei Spulautomaten mit Spulendornen für mehrere Spulen eine sehr grosse Masse kurzfristig beschleunigt werden muss, um die axiale Verschiebung durchzuführen. Der technische Aufwand für die Ver­schiebbarkeit des Dornes ist sehr hoch und schlägt sich folglich in den Herstellungskosten negativ nieder.This known device enables perfect thread takeover. However, it has the disadvantage that, particularly in the case of automatic winding machines with spindles for a plurality of spools, a very large mass must be accelerated in the short term in order to carry out the axial displacement. The technical effort required to move the mandrel is very high and consequently has a negative impact on the manufacturing costs.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, eine Vorrichtung zu schaffen, welche einen Fa­denwechsel von der vollen Spule zur leeren Hülse ohne Axialver­schiebung des Dornes ermöglicht.
Eine weitere Aufgabe der Erfindung besteht darin, die Wulstbil­dung auf der vollen Spulenoberfläche während des Einlegens des zulaufenden Fadens in den Fangschlitz weiterzuführen, bzw. den während des Spulenwechsels kontinuierlich zu laufenden Fadens zur Bildung des Wulstes zu verwenden.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of creating a device which enables a thread change from the full bobbin to the empty tube without axial displacement of the mandrel.
A further object of the invention is to continue the bead formation on the full bobbin surface while the incoming thread is being inserted into the catch slot, or to use the thread that is continuously running during the bobbin change to form the bead.

Es gelingt mit der erfindungsgemässen Vorrichtung, den zulaufen­den Faden innerhalb einer einer im wesentlichen senkrecht zur Drehachse der Spulendorne verlaufenden Ebene über der leeren Hülse zum Fangschlitz zu verschieben und gleichzeitig den noch zur vollen Spule zur Wulstbildung laufenden Faden axial unver­schiebbar zu halten.
Der zulaufende Faden kann von der Vorrichtung axial zweimal über den Fangschlitz geführt werden, so dass sichergestellt ist, dass der Faden, wenn dieser beim ersten Ueberlaufen des Fangschlitzes ausnahmsweise nicht erfasst wird, beim zweiten Ueberlauf ge­klemmt und mitgerissen wird.With the device according to the invention, it is possible to move the incoming thread within a plane that is essentially perpendicular to the axis of rotation of the bobbin spindles above the empty sleeve to the catch slot and at the same time to keep the thread that is still running to the full bobbin to form a bead axially immovable.
The incoming thread can be guided twice axially over the catch slot by the device, so that it is ensured that the thread, if it is exceptionally not detected when the catch slot overflows for the first time, is clamped and entrained in the second overflow.

Anhand zweier Ausführungsbeispiele wird die Erfindung näher er­läutert. Es zeigen:

  • Figur 1 eine schematische Darstellung eines Spulautomaten mit vier Spulen,
  • Figur 2 eine perspektivische Darstellung der fliegenden Enden der beiden Spulendorne (ausschnittsweise),
  • Figur 3 eine Ansicht des Fadenleitbleches von unten (im Bereich des Mitnehmers aufgeschnitten),
  • Figur 4 eine Ansicht des Fadenleitbleches in Figur 3 aus Rich­tung Pfeil 8 (teilweise aufgeschitten) und
  • Figur 5 eine schematische Darstellung des Fadenlaufes beim Spu­lenwechselvorgang.
The invention is explained in more detail using two exemplary embodiments. Show it:
  • FIG. 1 shows a schematic illustration of an automatic winder with four bobbins,
  • FIG. 2 shows a perspective illustration of the flying ends of the two coil mandrels (in sections),
  • Figure 3 is a view of the thread guide plate from below (in the area of the driver cut open),
  • Figure 4 is a view of the thread guide plate in Figure 3 from the direction of arrow 8 (partially cut) and
  • Figure 5 is a schematic representation of the thread path during the bobbin changing process.

In Figur 1 ist ein Spulautomat mit zwei auf einem Revolver ge­lagerten Spulendornen 3 und 5, einer Fadenverlegevorrichtung 7 bekannter Bauweise sowie das Maschinengehäuse 9 gezeigt, welches die Antriebsmotoren für die Spulendorne 3,5, die Verlegevorrich­tung 7 und die übrigen Aggregate sowie Teile der Steuerung ent­hält. Der die beiden Spulendorne 3 und 5 tragende Revolver ist nicht dargestellt und weist eine bekannte Bauweise auf. Die bei­den Spulendorne 3 und 5 sind fliegend gelagert, wodurch eine Be­schickung mit leeren Hülsen 11 bzw. Entnahme der vollen Garnspu­len 13 von Hand oder durch einen automatischen Doffer erfolgen kann.In Figure 1, an automatic winder with two spools 3 and 5 mounted on a turret, a thread laying device 7 of known construction and the machine housing 9 is shown, which contains the drive motors for the winding mandrel 3, 5, laying device 7 and the other units and parts of the control . The turret carrying the two mandrels 3 and 5 is not shown and has a known construction. The two spools 3 and 5 are overhung, which means that empty tubes 11 can be loaded or the full spools 13 can be removed by hand or by an automatic doffer.

Oberhalb der in den Figuren 1,2 und 5 durch Drehen des Revolvers nach oben geschwenkten Spulendorne 3 mit der leeren Hülse 11 ist ein Fadenführerblech 15 angeordnet, welches während des Spulen­wechselvorganges den zulaufenden Faden 17 aus dem in Figur 2 in gebrochenen Linien gezeigten Fadenlauf X, welcher in einer zu den Drehachsen A und C der Spulendorne 3 und 5 senkrecht stehen­den imaginären Ebene verläuft, in Richtung des Pfeiles D in einen die Fadenübernahme durch die leere Spule 11 ermöglichenden Fadenlauf Y ausgelenkt wird. Zum Uebernehmen des Fadens 17 ist in der Hülse 11 ein umlaufender Fadenfangschlitz 19 angebracht. Der Faden 17 wird nach dem Drehen des Revolvers durch die leere Hülse 11 aus dem gestreckten Fadenlauf Y ausgelenkt und um­schlingt die Mantelfläche der Hülse 11 in einen begrenzten Win­kelbereich.
Ein Fadenleitblech 21 ist an dem die Fadenverlegevorrichtung 7 aufnehmenden Gehäuse 23 schwenk- oder verschiebbar gelagert, derart, dass dessen vordere Kante 25 den Faden 17 zwischen den beiden Spulendornen 3 und 5 aus lenkt. In Figur 5 ist in strich­punktierter Linie der Fadenlauf beim Einschwenken des Fadenleit­bleches 21 und in ausgezogener Linie nach dem Zurückziehen dar­ gestellt. Am Fadenleitblech ist ein im wesentlichen v-förmiger Einschnitt 27 angebracht, bei dem der eine Schenkel als bogen­förmige Kurve 29 ausgebildet ist. Die Ausbildung der Kurve 29 wird anhand der Figur 3 näher erläutert. Auf der bogenförmigen Seite des Einschnittes 27 ist im Fadenleitblech 21 ein senkrecht zu dessen Vorderkante 25 verschiebbar angeordneter Fadenmitneh­mer 31 eingesetzt. Der Fadenmitnehmer 31 ist an einem in einer Nut 33 geführten Gleiter 35 befestigt und weist einen Mitnehmer­haken 36 auf, welcher unter einem Winkel von weniger als 90° zur Unterfläche des Fadenleitbleches 21 steht und vom Einschnitt 27 wegweist.A thread guide plate 15 is arranged above the bobbin mandrel 3 with the empty sleeve 11, which is pivoted upward by rotating the revolver, and which during the bobbin changing process removes the incoming thread 17 from the thread path X shown in broken lines in FIG. 2, which runs in an imaginary plane perpendicular to the axes of rotation A and C of the bobbin mandrels 3 and 5, is deflected in the direction of the arrow D into a yarn path Y which enables the yarn to be taken over by the empty bobbin 11. To take over the thread 17, a circumferential thread catch slot 19 is provided in the sleeve 11. After turning the revolver, the thread 17 is deflected by the empty sleeve 11 out of the stretched yarn path Y and wraps around the outer surface of the sleeve 11 in a limited angular range.
A thread guide plate 21 is pivotally or displaceably mounted on the housing 23 accommodating the thread laying device 7 such that its front edge 25 deflects the thread 17 between the two bobbin spindles 3 and 5. In FIG. 5, the thread run is shown in dash-dotted line when the thread guide plate 21 is pivoted in and in a solid line after the retraction posed. An essentially V-shaped incision 27 is made on the thread guide plate, in which one leg is designed as an arcuate curve 29. The formation of curve 29 is explained in more detail with reference to FIG. 3. On the arc-shaped side of the incision 27, a thread driver 31 is inserted in the thread guide plate 21 and is displaceable perpendicularly to its front edge 25. The thread driver 31 is fastened to a slider 35 guided in a groove 33 and has a driver hook 36 which is at an angle of less than 90 ° to the lower surface of the thread guide plate 21 and points away from the incision 27.

Das Fadenleitblech 21 besteht aus zwei in geringem Abstand zu­einander angeordneten, ein Kastenprofil bildenden Blechteilen 37 und 39 (Figuren 3 und 4). Im untenliegenden Blechteil 37 ist die Nut 33 eingelassen, welche zur Führung des Gleiters 35 dient. Der Gleiter 35 kann T-förmig ausgebildet sein (Fig. 4); oder es können am Gleiter 35 zwei die Nut 33 durchdringende Führungsbol­zen 41 angebracht sein, von denen der eine als Fadenmitnehmerha­ken 36 ausgebildet sein kann.
Am Gleiter 35 ist ein Kabel oder ein Seil 43 befestigt, das zu einer Umlenkrolle 45 führt, welche im Bereich der hinteren Kante 47 im Innern des Fadenleitbleches 21 angeordnet ist. Von der Rolle 45 führt das Seil 43 entweder zu einer Zugeinrichtung oder endet ausserhalb des Fadenleitbleches 21 z.B. in einer von Hand ergreifbaren Schlaufe 49. Ein auf einer Achse E schwenkbar be­festigter Betätigungshebel 51 steht in Anlage mit dem rücksei­tigen Ende des Gleiters 35 und wird mittels einer Feder 53 an diesen angepresst.The thread guide plate 21 consists of two sheet metal parts 37 and 39 which are arranged at a short distance from one another and form a box profile (FIGS. 3 and 4). In the underlying sheet metal part 37, the groove 33 is inserted, which serves to guide the slider 35. The slider 35 can be T-shaped (Fig. 4); or two guide bolts 41 penetrating the groove 33 can be attached to the slider 35, one of which can be designed as a thread driver hook 36.
A cable or rope 43 is attached to the slider 35, which leads to a deflection roller 45 which is arranged in the area of the rear edge 47 inside the thread guide plate 21. From the pulley 45, the cable 43 either leads to a pulling device or ends outside the thread guide plate 21, for example in a loop 49 which can be gripped by hand. An actuating lever 51 which is pivotably mounted on an axis E is in contact with the rear end of the slider 35 and is by means of a Spring 53 pressed against this.

Im folgenden wird anhand der Figuren 2,3 und 5 die Funktions­weise der Vorrichtung näher erläutert.
Nach Erreichen des vorgegebenen Durchmessers wird die volle Spu­le 13 und die leere Hülse durch den Revolver um ca. 180° ge­schwenkt. Dabei gelangt die Oberfläche der leeren Hülse 11 in Kontakt mit dem Faden 17, der noch der vollen Spule 13 zugeführt wird. Damit dort ein Fadenwulst 55 gebildet werden kann, hält das in den Fadenlauf Y eingeschwenkte Fadenführerblech 15 den Faden 17 axial unverrückbar fest. Gleichzeitig oder kurz danach wird das Fadenleitblech 21 vorgeschoben oder geschwenkt, derart, dass dessen Vorderkante 25 den Faden 17 zwischen der Oberfläche der Hülse 11 und der vollen Spule 13 aus lenkt. Durch eine axiale Verschiebung des Fadenführerbleches 15 in Richtung des Pfeiles D gelangt der Faden 17 unter den Fadenmitnehmerhaken 36 und wird von diesem weiterhin derart geführt, dass der dem Fadenwulst zu­laufende Faden 17 in der imaginären, senkrecht zur Achse C ste­hende Ebene verläuft.
Damit der zulaufende Faden 17 vom Fadenfangschlitz 19 auf der leeren Hülse 11 erfasst werden kann, wird das Fadenleitblech 15 so weit axial nach rechts geschoben, bis dessen Führungsschlitz 16 in der Ebene durch den Fadenfangschlitz 19 zu liegen kommt. Gleichzeitig mit der Verschiebung des Fadenführerbleches 15 wird der Fadenmitnehmer 31 durch das Seil 43 unter dem Fadenleitblech 21 in Richtung des Pfeiles F zurückgezogen. Dabei gleitet der zulaufende Faden 17, der an der Kante 25 umgelenkt wird, über die Kurve 29 in den Grund 59 des Einschnittes 27. Der Grund 59 des Einschnittes 27 befindet sich in etwa in der Ebene durch den Fadenfangschlitz 19.
Während des Zurückziehens des Fadenmitnehmers 31 geht die Bil­dung des Fadenwulstes 55 auf der vollen Hülse 13 ungestört wei­ter, da der zulaufende Faden 17, obwohl dieser durch die Kurve nach rechts ausgelenkt worden ist, vom Fadenmitnehmerhaken 36 stets in der imaginären Ebene durch den Fadenwulst 55 gehalten wird.
In einer besonders vorteilhaften Ausgestaltung der Erfindung ist die Kurve 29 gemäss Figur 3 derart ausgebildet, dass der Faden 17 beim Zurückziehen des Fadenmitnehmers 31 den Fadenfangschlitz 19 zweimal überquert, d.h. dass der Scheitel 5 der Kurve 29 jen­seits der Ebene P durch den Fadenfangschlitz 19 liegt. Die Be­tätigung des Fadenmitnehmers 31 kann durch Ziehen von Hand an der Schlaufe 49 erfolgen; oder es kann ein elektrischer Antrieb für den Zug am Seil 43 vorgesehen werden. Beim Ziehen am Seil 43 wird die Feder 53 gespannt, welche nach Loslassen des Seiles 43 den Fadenmitnehmer 31 in die Ausgangsposition zurückfahren lässt.
Sobald der Faden über den Fadenfangschlitz 19 geführt wird, wird er von diesem festgeklemmt und auf der Hülse 11 aufgewickelt. Dabei reisst der zur vollen Spule 13 führende Fadenabschnitt von selbst, oder er wird mit einer entsprechenden Schneidvorrichtung getrennt. Sobald der Faden 19 vom Fangschlitz 19 erfasst worden ist, kann das Fadenführerblech 15 in die Ausgangslage zurückkeh­ren und den Faden 17 an die Fadenverlegevorrichtung 7 über­geben.The mode of operation of the device is explained in more detail below with reference to FIGS. 2, 3 and 5.
After the predetermined diameter has been reached, the full spool 13 and the empty sleeve are pivoted by the turret by approximately 180 °. The surface of the empty sleeve 11 comes into contact with the thread 17, which is still fed to the full bobbin 13. So that a thread bead 55 can be formed there, the thread guide plate 15 pivoted into the thread path Y holds the thread Thread 17 axially immovably tight. Simultaneously or shortly thereafter, the thread guide plate 21 is advanced or pivoted in such a way that its front edge 25 deflects the thread 17 between the surface of the sleeve 11 and the full bobbin 13. Through an axial displacement of the thread guide plate 15 in the direction of arrow D, the thread 17 passes under the thread driver hook 36 and is guided by it in such a way that the thread 17 running towards the thread bead runs in the imaginary plane perpendicular to the axis C.
So that the incoming thread 17 can be gripped by the thread catch slot 19 on the empty sleeve 11, the thread guide plate 15 is pushed axially to the right until its guide slot 16 comes to lie in the plane through the thread catch slot 19. Simultaneously with the displacement of the thread guide plate 15, the thread driver 31 is pulled back by the rope 43 under the thread guide plate 21 in the direction of the arrow F. The incoming thread 17, which is deflected at the edge 25, slides over the curve 29 into the bottom 59 of the incision 27. The bottom 59 of the incision 27 is located approximately in the plane through the thread catching slot 19.
During the retraction of the thread driver 31, the formation of the thread bead 55 on the full sleeve 13 continues undisturbed, since the incoming thread 17, although this has been deflected to the right by the curve, is always held in the imaginary plane by the thread bead 55 by the thread driver hook 36 becomes.
In a particularly advantageous embodiment of the invention, the curve 29 according to FIG. 3 is designed such that the thread 17 crosses the thread catch slot 19 twice when the thread driver 31 is withdrawn, ie the vertex 5 of the curve 29 lies beyond the plane P through the thread catch slot 19. The thread driver 31 can be actuated by pulling the loop 49 by hand; or an electric drive for the pull on the rope 43 can be provided. When pulling the rope 43, the spring 53 is tensioned, which after the rope 43 has been released lets the thread driver 31 return to the starting position.
As soon as the thread is passed over the thread catch slot 19, he clamped by this and wound on the sleeve 11. The thread section leading to the full bobbin 13 tears by itself, or it is separated with a corresponding cutting device. As soon as the thread 19 has been caught by the catch slot 19, the thread guide plate 15 can return to the starting position and transfer the thread 17 to the thread laying device 7.

Die Erfindung ist am Beispiel eines Fadenmitnehmers 31 und eines Einschnittes 27 beschrieben worden. Selbstverständlich weist ein Spulautomat 1 mit mehreren nebeneinander angeordneten Spulen 13 eine entsprechende Anzahl von Mitnehmern 31 und Einschnitten 27 auf.The invention has been described using the example of a thread driver 31 and an incision 27. Of course, an automatic winder 1 with a plurality of coils 13 arranged next to one another has a corresponding number of drivers 31 and cuts 27.

Die Erfindung bezieht sich daher auf ein Wechselsystem für eine Fadenpositionierung bei Spulern während des Wechselvorgangs bei einem Spulautomaten, bei dem zwei Spulendorne gelagert und antreibbar sind, bei denen nach dem Aufbaueiner vollen Packung ein Wechsel stattfindet, wobei der aufzuspulende Faden von der vollen Packung auf den Fangschlitz einer Leerhülse umgeleitet wird.The invention therefore relates to a changing system for thread positioning in bobbins during the changing process in an automatic winder, in which two bobbins are stored and can be driven, in which a change takes place after the construction of a full package, the thread to be wound from the full package to the Catch slot of an empty tube is redirected.

In der vorliegenden Erfindung sind zur Umlenkung des Fadens zwei Führungsmittel vorgesehen, wobei ein Führungsmittel axial verschiebbar ist und das zweite Führungsmittel den Faden über eine Kurvenbahn in Verbindung mit einem geeigneten Zugmittel in Bezug auf die Spulendornachse axial verlagert. In einer weiteren Ausgestaltung des Anmeldungsgegenstandes ist vorgesehen, dass ein Abhebeblech vorgesehen ist, das den Faden aus einer Changiervorrichtung entfernt, wobei der Faden vom Schiebeblech durch Axialverschiebung positionierbar ist.In the present invention, two guide means are provided for deflecting the thread, one guide means being axially displaceable and the second guide means displacing the thread axially with respect to the bobbin mandrel axis in connection with a suitable traction means. In a further embodiment of the subject of the application it is provided that a lifting plate is provided which removes the thread from a traversing device, the thread being positionable by axial displacement from the sliding plate.

Beim Anmeldungsgegenstand ist das Wechselblech mit Rückzugshaken ausgerüstet, durch die der Faden über eine Kurvenbahn lenkbar it. Durch die Umlenkung einerseits über das Schiebeblech und andererseits über das Wechselblech lässt sich dadurch vermeiden, dass man aufwendige Vorrichtungen zur Erzeugung einer Relativbewegung der Spulendorne einsetzen muss. Eine besonders konstruktiv einfache Lösung besteht darin, dass die Rückzugshaken über einen Seilzug betätigbar sind. Andererseits wäre es aber auch denkbar, dass diese Haken über motorische Antriebe in Bewegung versetzt werden.In the subject of the application, the interchangeable plate is equipped with a retraction hook, through which the thread can be steered via a curved path. The deflection on the one hand over the sliding plate and on the other hand over the interchangeable plate makes it possible to avoid the need to use complex devices for producing a relative movement of the coil mandrels. A particularly structurally simple solution is that the retraction hooks can be actuated via a cable pull. On the other hand, it would also be conceivable for these hooks to be set in motion by means of motor drives.

Beim Anmeldungsgegenstand übernimmt das Wechselblech eine zweite Funktion: Nach der Revolverdrehung kann das Wechselblech zwischen der vollen Packung und der neuen Packung positioniert werden, so dass weitestgehend ausgeschlossen ist, dass das abgetrennte Fadenende in die neue laufende Packung eingespult wird.With the subject of the application, the interchangeable plate takes on a second function: after the turret has been rotated, the interchangeable plate can be positioned between the full pack and the new pack, so that it is largely excluded that the separated thread end is wound into the new, running pack.
