Definitions
- 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.
- the incoming thread 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.
- the empty bobbin tube gets into this thread run.
- GB-A-2015046 has a thread guide rod attached to the turret, which is rotated together with the bobbins when changing the bobbin and gets into the thread path between the empty and full bobbins.
- a slot arranged on the thread guide rod causes a deflection and thus relocation of the incoming thread into the area of the thread catching slot on the empty tube.
- the thread guide rod which is firmly attached to the turret, inevitably enters the thread run when the turret is turned. It is not possible to determine the location, the time and the course of the axial displacement of the thread independently of the angle of rotation of the turret.
- the invention has for its main object to provide a device in which the axial displacement of the thread between the full bobbin and the empty tube to form a thread bead on the full bobbin and for inserting the incoming thread into the catch slot of the empty tube independently of the rotational position of the revolver can take place.
- 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.
- FIG. 1 shows an automatic winder with two winding mandrels 3 and 5 mounted on a turret, a thread laying device 7 of known construction and the machine housing 9, 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 bobbin mandrels 3 and 5 are overhung, which means that empty tubes 11 can be loaded or the full bobbins 13 can be removed by hand or by an automatic doffer.
- a thread guide plate 15 is arranged above the bobbin mandrel 3 with the empty sleeve 11, which is swiveled 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.
- a circumferential thread catch slot 19 is provided in the sleeve 11.
- a thread guide plate 21 is pivotally or displaceably mounted on the housing 23 receiving the thread laying device 7 such that its front edge 25 deflects the thread 17 between the two bobbin spindles 3 and 5.
- FIG. 5 the thread path when the thread guide plate 21 is pivoted in is shown in a dash-dotted line and in a solid line after the retraction.
- 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.
- 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.
- 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).
- 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 roll 45, the rope 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.
- 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.
- 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.
- 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 bottom 59 of the incision 27 is located approximately in the plane through the thread catching slot 19.
- 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.
- 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.
- the spring 53 is tensioned, which after the rope 43 has been released lets the thread driver 31 return to the starting position.
- 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.
- the thread guide plate 15 can return to the starting position and transfer the thread 17 to the thread laying device 7.
- the invention therefore relates to a changing system for thread positioning in bobbins during the changing process in an automatic winder, in which two bobbin spindles 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 onto the Catch slot of an empty tube is redirected.
- 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.
- a lifting plate is provided which removes the thread from a traversing device, the thread being positionable by axial displacement from the sliding plate.
- the interchangeable plate is equipped with retraction hooks through which the thread can be steered via a curved path.
- the deflection, on the one hand, via the sliding plate and, on the other hand, via the interchangeable plate, makes it possible to avoid having 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.
- these hooks are set in motion by means of motor drives.
- 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.

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
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 Drenen des Revolvers, gelangt die leere Spulenhülse in diesen Fadenlauf.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 the turret is thrown, the empty bobbin tube gets into this thread run.
Bei der GB-A-2015046 ist am Revolver eine Garnführungsstange angebracht, die zusammen mit den Spulen beim Spulenwechsel gedreht wird und in den Fadenlauf zwischen der leeren und der vollen Spule gelangt. Ein auf der Fadenführungsstange angeordneter Schlitz bewirkt eine Umlenkung und damit Verlegung des zulaufenden Fadens in den Bereich des Fadenfangschlitzes auf der leeren Hülse.GB-A-2015046 has a thread guide rod attached to the turret, which is rotated together with the bobbins when changing the bobbin and gets into the thread path between the empty and full bobbins. A slot arranged on the thread guide rod causes a deflection and thus relocation of the incoming thread into the area of the thread catching slot on the empty tube.
Der Eintritt der auf dem Revolver fest angebrachten Fadenführerstange in den Fadenlauf erfolgt beim Drehen des Revolvers zwangsläufig. Es ist nicht möglich, den Ort, den Zeitpunkt und den Ablauf des axialen Verschiebens des Fadens unabhängig vom Drehwinkel des Revolvers zu bestimmen.The thread guide rod, which is firmly attached to the turret, inevitably enters the thread run when the turret is turned. It is not possible to determine the location, the time and the course of the axial displacement of the thread independently of the angle of rotation of the turret.
Der Erfindung liegt hauptsächlich die Aufgabe zugrunde, eine Vorrichtung zu schaffen, bei der die axiale Verschiebung des Fadens zwischen der vollen Spule und der leeren Hülse zur Bildung eines Fadenwulstes auf der vollen Spule und zum Einführen des zulaufenden Fadens in den Fangschlitz der leeren Hülse unabhängig von der Drehlage des Revolvers erfolgen kann.The invention has for its main object to provide a device in which the axial displacement of the thread between the full bobbin and the empty tube to form a thread bead on the full bobbin and for inserting the incoming thread into the catch slot of the empty tube independently of the rotational position of the revolver can take place.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruches 1.This object is achieved by the characterizing features of
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.

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.FIG. 1 shows an automatic winder with two
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 dargestellt. 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
A
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

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 S 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.

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
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 bobbin spindles 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 onto 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 ist. Durch die Umlenkung einerseits über das Schiebeblech und andererseits über das Wechselblech lässt sich 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 retraction hooks through which the thread can be steered via a curved path. The deflection, on the one hand, via the sliding plate and, on the other hand, via the interchangeable plate, makes it possible to avoid having 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 that these hooks are 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.
