Abstract

In a spinning-winding machine in which the continuously fed thread is wound on by means of a traversing thread guide to form a bobbin and during the bobbin change is clamped and cut off in a clamping and cutting zone next to the tube, the traversing thread guide guides the thread from the spooling region to the clamping and cutting zone, and then back again into the spooling region. For this purpose, the traversing thread guide is fastened displaceably on the thread-guide rod and is displaced by means of a displacement means to the cutting and clamping device. The invention allows trouble-free bobbin change even at high spooling speeds. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Spulenwechsel an einer Spinn-Spulmaschine, bei der der angelieferte Faden mittels eines sich in einem Spulbereich bewegenden Chan­gierfadenführers zu einer Spule aufgewickelt und nach dem Auswechseln einer vollen Spule gegen eine leere Hülse in einer Klemm- und Schneidzone seitlich neben der Hülse festgeklemmt und abgeschnitten wird. Die Erfindung be­trifft ferner eine Vorrichtung zum Durchführen des Ver­fahrens.The invention relates to a method for changing bobbins on a spinning bobbin winder, in which the delivered thread is wound into a bobbin by means of a traversing thread guide moving in a bobbin area and after the replacement of a full bobbin with an empty tube in a clamping and cutting zone to the side of the Sleeve is clamped and cut off. The invention further relates to an apparatus for performing the method.

Zur Durchführung des Spulenwechsels wurde bereits vorge­schlagen, die Arbeitsgeschwindigkeit der Spinnmaschine herabzusetzen, den Changierfadenführer in seiner linken Endstellung stillzusetzen und eine in einen Hülsenträger eingelegte leere Hülse, die zuvor durch Verschwenken des Hülsenträgers in unmittelbare Nähe der vollen Spule gebracht wurde, nach dem Auswurf der vollen Spule aus dem Spulenträger an die Wickelwelle anzudrücken (DE-OS 2.503.545). Der Faden wird dann durch ein Fadenablenk­blech neben die linke Stirnseite der Hülse gedrückt, wo er in den Wirkbereich eines Messers kommt und beim Schließen des Spulenträgers zwischen dem Hülsenteller und der Hülse festgeklemmt wird. Durch die Drehbewegung der Hülse wird schließlich das die Hülse mit der freige­setzten vollen Spule verbundene Fadenstück am Messer abgerissen.To carry out the bobbin change, it has already been proposed to reduce the working speed of the spinning machine, to stop the traversing thread guide in its left end position and to insert an empty tube inserted into a tube carrier, which was previously brought into close proximity to the full bobbin by pivoting the tube carrier after the ejection of the full one Press the bobbin out of the bobbin onto the winding shaft (DE-OS 2.503.545). The thread is then pressed through a thread deflector next to the left end of the sleeve, where it comes into the effective range of a knife and is clamped between the sleeve plate and the sleeve when closing the bobbin. By rotating the sleeve, the piece of thread connected to the sleeve with the released full bobbin is finally torn off on the knife.

Nachteilig bei diesem Verfahren ist, daß es für hohe Spulgeschwindigkeiten nicht geeignet und auch nur dann anwendbar ist, wenn alle Spulen der Maschine gleichzeitig gewechselt werden.A disadvantage of this method is that it is not suitable for high winding speeds and can only be used if all the bobbins of the machine are changed at the same time.

Nach einem anderen bekannten Vorschlag wird der von der Vorrichtung kontinuierlich weitergelieferte Faden vor dem Spulenwechsel oberhalb der Abzugswalzen durchgetrennt und in eine Schwenkdüse eingeführt, durch deren Verschwen­kung der Faden nach dem Austausch der vollen Spule gegen eine leere Hülse und bei noch nicht vollständig ge­schlossenem Spulenhalter in den Spalt zwischen der Hülse und dem Zentrierkopf des Spulenhalters gelangt (DE-OS 2.312.609). Dort oder auch innerhalb des Zentrierkopfes selbst wird der Faden beim Schließen des Spulenhalters festgeklemmt und durch eine an der Mündung der Schwenk­düse befestigte Schere abgetrennt. Zum Bilden einer Faden­reserve auf der Hülse wird der Faden durch einen Leit­draht aus dem Bereich des Changierfadenführers fernge­halten. Nach Fertigstellung der Fadenreserve neben der eigentlichen Spulenwicklung wird der Faden vom Leitdraht heruntergedrückt, so daß er vom Changierfadenführer er­faßt und dem Spulenaufbau entsprechend verlegt werden kann.According to another known proposal, the thread continuously supplied by the device is cut through before the bobbin change above the take-off rollers and introduced into a swivel nozzle, by pivoting the thread after replacing the full bobbin with an empty tube and with the bobbin holder not yet fully closed Gap between the sleeve and the centering head of the coil holder reaches (DE-OS 2.312.609). There, or within the centering head itself, the thread is clamped when the bobbin holder is closed and separated by a pair of scissors attached to the mouth of the swivel nozzle. To form a thread reserve on the sleeve, the thread is kept away from the area of the traversing thread guide by a guide wire. After completion of the thread reserve next to the actual bobbin winding, the thread is pressed down by the guide wire, so that it can be gripped by the traversing thread guide and laid according to the bobbin structure.

Auch diese Handhabung des Fadens ist für hohe Maschinen­geschwindigkeiten nicht geeignet, bei denen insbesondere auch die Gefahr besteht, daß der Faden vom Changierfaden­führer nicht erfaßt wird.This handling of the thread is also not suitable for high machine speeds at which there is in particular the risk that the thread will not be caught by the traversing thread guide.

Aufgabe der vorliegenden Erfindung ist es, die Nachteile der bekannten Vorschläge zu vermeiden und ein Verfahren zum Führen und Trennen eines Fadens und eine Vorrichtung dafür zu schaffen, die es ermöglichen, den Spulenwechsel auch bei hohen Spulgeschwindigkeiten störungsfrei durch­zuführen.The object of the present invention is to avoid the disadvantages of the known proposals and to provide a method for guiding and separating a thread and a device therefor, which make it possible to carry out the bobbin change without problems even at high bobbin speeds.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Changierfadenführer den Faden aus dem Spulbereich bis in die Klemm- und Schneidzone und danach wieder zu­rück in den Spulbereich führt.The object is achieved in that the traversing thread guide leads the thread from the winding area into the clamping and cutting zone and then back into the winding area.

Um Fadenabschläge von der Spule zu verhindern, wird der Faden bei seiner Überführung in die Klemm- und Schneid­zone senkrecht zur Spulenachse ausgelenkt. Zweckmäßig bringt der Changierfadenführer den Faden in der Klemm- und Schneidzone vor die Mündung eines Saugrohres, durch das hindurch der von der Spinnvorrichtung kontinuierlich weitergelieferte Faden abgesaugt werden kann.In order to prevent thread strikes from the bobbin, the thread is deflected perpendicularly to the bobbin axis when it is transferred to the clamping and cutting zone. The traversing thread guide expediently brings the thread in the clamping and cutting zone in front of the mouth of a suction pipe, through which the thread continuously supplied by the spinning device can be sucked off.

Das Aufwickeln einer Fadenreserve ohne zusätzliche Hilfs­mittel wird dadurch ermöglicht, daß der Changierfadenfüh­rer zum Bilden einer Fadenreservewicklung neben dem Spul­bereich hin- und herbewegt wird. Vorzugsweise wird der Faden nach dem Auswechseln der Spule gegen eine leere Hülse zuerst geschnitten und dann geklemmt, wobei die Klemmung zweckmäßig solange aufrechterhalten wird, bis die Fadenreserve aufgewickelt ist.The winding of a thread reserve without additional aids is made possible in that the traversing thread guide is moved back and forth to form a thread reserve winding next to the winding area. Preferably, the thread is first cut and then clamped after the bobbin is replaced with an empty tube, the clamping advantageously being maintained until the thread reserve is wound up.

Die Vorrichtung zum Durchführen des Verfahrens ist da­durch gekennzeichnet, daß der Changierfadenführer lösbar auf der Fadenführerstange befestigt und ihm ein Verschie­bemittel zugeordnet ist, das ihn mit dem in ihm geführten Faden auf der Fadenführerstange zur Schneid- und Klemm­vorrichtung verschiebt. Eine besonders leichte und schnel­ le Abkopplung und Verschiebung des Changierfadenführers wird dadurch ermöglicht, daß der Changierfadenführer durch einen auf der Fadenführerstange angeordneten Permanentmagneten in der Spinnstellung gehalten ist. Die Rückstellung des Changier­fadenführers zum Bilden der Fadenreserve auf der Hülse er­folgt auf einfache Weise durch eine Druckfeder.The device for performing the method is characterized in that the traversing thread guide is releasably attached to the thread guide rod and a displacement means is assigned to it, which moves it with the thread guided in it on the thread guide rod to the cutting and clamping device. A particularly light and fast Decoupling and displacement of the traversing thread guide is made possible in that the traversing thread guide is held in the spinning position by a permanent magnet arranged on the thread guide rod. The traversing thread guide is reset to form the thread reserve on the sleeve in a simple manner by means of a compression spring.

In einer zweckmäßigen Weiterbildung der Vorrichtung ist das Verschiebemittel auf einer Gewindespindel angeordnet. Deren Umdrehung in der einen oder anderen Richtung wird durch einen umsteuerbaren Motor sichergestellt. Die Schneid- und Klemmvorrichtung ist in einer raumsparenden Anordnung einem Spulteller zugeordnet und bildet mit diesem eine Bauein­heit. Die Schneid- und Klemmvorrichtung wird dadurch weiter optimiert, daß sie einen Bolzen enthält, der in einer durch eine Ringnut angeschnittenen Bohrung quer zur Fadenlaufrich­tung verschiebbar und mit einer eine Nut begrenzenden Schneidkante und Klemmkante versehen ist, die in Fadenlauf­richtung hintereinander angeordnet sind und mit einer durch den Anschnitt der Bohrung gebildeten Kante als Gegenelement zusammenwirken. Dadurch wird ein rascher und definierter Schnitt sowie ein sicheres Festklemmen des Fadens erreicht. Zweckmäßig sind die Schneidkante und die Klemmkante nachein­ander dem Gegenelement zustellbar. Das Absaugen des Fadens ermöglicht ein in der radialen Ebene der Ringnut schwenkbar gelagertes Saugrohr, das auch den Faden in die Schneid- und Klemmvorrichtung einlegt. Eine in den der Schneid- und Klemmeinrichtung benachbarten Endbereich der Spule schwenkbar gelagerte Fadenumlenkgabel verhindert, daß beim Herausschie­ben des Changierfadenführers mit dem Faden aus dem Spulbe­reich Fadenwicklungen von der Spule abfallen.In an expedient development of the device, the displacement means is arranged on a threaded spindle. Their rotation in one direction or the other is ensured by a reversible motor. The cutting and clamping device is assigned to a spool plate in a space-saving arrangement and forms a structural unit with the latter. The cutting and clamping device is further optimized in that it contains a bolt which is displaceable transversely to the thread running direction in a bore cut through an annular groove and is provided with a groove-defining cutting edge and clamping edge which are arranged one behind the other in the thread running direction and with one through the cut of the hole formed edge cooperate as a counter element. This ensures a quick and defined cut as well as a secure clamping of the thread. The cutting edge and the clamping edge are expediently deliverable to the counter element one after the other. The suction of the thread enables a suction tube which is pivotably mounted in the radial plane of the ring groove and which also inserts the thread into the cutting and clamping device. A thread deflecting fork pivotally mounted in the end region of the bobbin adjacent to the cutting and clamping device prevents thread windings from falling off the bobbin when the traversing thread guide is pushed out with the thread from the winding region.

Die Spulenhülse 2 ist beidseitig in einem Spulenhalter (nicht gezeigt) gehalten, an dessen Haltearmen Spulenteller 22 drehbar gelagert sind, die jeweils mit einer Zentrier­schulter in die Hülsenenden eingreifen. Die Spulenhülse 2 bzw. Spule 21 wird von einer Treibtrommel 3 angetrieben, gegen die sie gedrückt wird.The thread continuously supplied by the spinning device is wound up by means of a traversing thread guide 1 on a bobbin tube 2 in a cross winding to form a bobbin 21. The spool sleeve 2 is held on both sides in a spool holder (not shown), on the holding arms of which spool plates 22 are rotatably mounted, each of which engages with a centering shoulder in the sleeve ends.

Dabei wird ein Kippen des Changierfadenführers 1 um die Achse der Fadenführerstange 11 durch eine Führungsstan­ge 13 verhindert, auf der der Changierfadenführer 1 gleitet. Die Endstellung 1ʹ wird durch einen ortsfesten Anschlag 43 und eine Druckfeder 44 begrenzt, die auf der Führungs­stange 13 gehalten und am Anschlag 43 befestigt ist.The traversing thread guide 1 is assigned a displacement means 4 which is mounted on a threaded spindle 41. The threaded spindle 41 can be driven by a reversible motor 42. By means of the displacement means 4, the traversing thread guide 1, as will be described in more detail, can be moved on the thread guide rod 11 in the direction of a sleeve end and beyond this into an end position 1ʹ. Tilting of the traversing thread guide 1 about the axis of the thread guide rod 11 is prevented by a guide rod 13 on which the traversing thread guide 1 slides. The end position 1ʹ is limited by a fixed stop 43 and a compression spring 44, which is held on the guide rod 13 and attached to the stop 43.

In der Endstellung 1ʹ befindet sich der Changierfadenfüh­rer 1 in einem Bereich, in dem der von der Spinnvorrichtung kontinuierlich weitergelieferte Faden beim Spulenwechsel geklemmt und abgeschnitten wird. Die hierfür benötigte Klemm- und Schneidvorrichtung 5 bildet in dem gezeigten und bevor­zugten Ausführungsbeispiel mit dem Spulenteller 22 eine Baueinheit 6 und enthält einen Bolzen 51, der mit geringem Spiel in einer Bohrung 7 gelagert ist, die durch eine in der Baueinheit 6 vorgesehene Ringnut 61 angeschnitten ist (Fig. 3). Der Bolzen 51 ist mit einer Nut 52 versehen, die in bezug auf die Ringnut 61 in der Baueinheit 6 geneigt angeord­net ist, und in der Bohrung quer zur Fadenlaufrichtung ver­schiebbar.In the end position 1ʹ, the traversing thread guide 1 is located in an area in which the thread continuously supplied by the spinning device is clamped and cut off when the bobbin is changed. The clamping and cutting device 5 required for this forms in the preferred embodiment shown and with the bobbin 22 a unit 6 and contains a bolt 51 which is mounted with little play in a bore 7 which is cut by an annular groove 61 provided in the unit 6 is (Fig. 3). The bolt 51 is provided with a groove 52, which is arranged inclined with respect to the annular groove 61 in the structural unit 6, and is displaceable in the bore transverse to the thread running direction.

In der Ausgangsstellung des Bolzens 51 liegen die Nut 52 und die Ringnut 61 in der gleichen Rotationsebene. Der Bol­zen 51 ragt in radialer Richtung mit seiner Nut 52 über den Grund der Ringnut 61 hinaus, so daß der zulaufende Fa­den in der Nut 52 plaziert werden kann. Die Nut 52 wird durch eine Schneidkante 53 und eine Klemmkante 54 begrenzt, die in Fadenlaufrichtung hintereinander angeordnet sind. Der Bolzen 51 ist aus seiner in Figur 3 gezeigten Ausgangsstellung quer zur Ringnut 61 und der Fadenlaufrichtung in Richtung zur Spule 21 soweit verschiebbar, daß die Schneidkante 53 und die Klemmkante 54 der Nut 52 in Funktionskontakt mit der als Gegenelement wirkenden, freiliegenden Kante 71 der Bohrung 7 kommen.In the starting position of the bolt 51, the groove 52 and the annular groove 61 lie in the same plane of rotation. The bolt 51 protrudes in the radial direction with its groove 52 beyond the base of the annular groove 61, so that the tapering thread can be placed in the groove 52. The groove 52 is delimited by a cutting edge 53 and a clamping edge 54, which are arranged one behind the other in the thread running direction. The bolt 51 can be displaced from its initial position shown in FIG. 3 transversely to the annular groove 61 and the thread running direction in the direction of the bobbin 21 such that the cutting edge 53 and the clamping edge 54 of the groove 52 are in functional contact with the exposed edge 71 of the bore, which acts as a counter element 7 come.

Die Verschiebung des Bolzens 51 wird durch eine Druckstan­ge 62 bewirkt, deren keilförmig ausgebildetes Ende an einem an der Stirnseite des Bauteiles 6 herausragenden Fortsatz 55 des Bolzens 51 angreift. Eine Abflachung 56 am Fortsatz 55 sichert den Bolzen 51 gegen Verdrehung (Figur 4). Die Druckstange 62 ist an einem Ende eines zweiarmigen Hebels 63 angeordnet, der mittels eines doppelt wirkenden Hubmagneten 64 um eine Achse 65 schwenkbar ist. Das andere freie Ende des Hebels 63 trägt eine Rolle 66. Die Rückstellung des Bolzens 52 in die Ausgangsstellung erfolgt durch eine Druckfeder 72.The displacement of the bolt 51 is effected by a push rod 62, the wedge-shaped end of which engages on an extension 55 of the bolt 51 which projects on the end face of the component 6. A flattened portion 56 on the extension 55 secures the bolt 51 against rotation (FIG. 4). The push rod 62 is arranged at one end of a two-armed lever 63 which can be pivoted about an axis 65 by means of a double-acting lifting magnet 64. The other free end of the lever 63 carries a roller 66. The return of the bolt 52 to the starting position is carried out by a compression spring 72.

In der Klemm- und Schneidzone des Fadens sind ferner eine Fadenumlenkgabel 8 und ein Saugrohr 9 angeordnet (Figuren 1 und 2). Die Fadenumlenkgabel 8 ist um eine in Nähe der Stirnseite der Spule 21 und senkrecht zur Hülsenachse lie­gende Schwenkachse aus einer Ruhestellung unterhalb des auf die Spule 21 auflaufenden Fadens in den Fadenlaufweg schwenkbar. Das Saugrohr 9 ist um eine parallel zur Hülsen­achse angeordnete Achse 91 aus einer im wesentlichen hori­zontalen Fadenaufnahmestellung 9ʹ unterhalb der Ringnut 61 nach aufwärts in eine Stellung hinterhalb der Ringnut 61 schwenkbar.In the clamping and cutting zone of the thread, a thread deflection fork 8 and a suction pipe 9 are also arranged (FIGS. 1 and 2). The thread deflecting fork 8 can be pivoted about a pivot axis lying near the end face of the spool 21 and perpendicular to the sleeve axis from a rest position below the thread running onto the spool 21 into the thread path. The suction pipe 9 can be pivoted about an axis 91 arranged parallel to the sleeve axis from an essentially horizontal thread take-up position 9ʹ below the annular groove 61 to a position behind the annular groove 61.

Die Arbeitsweise der Vorrichtung ist folgende:The device works as follows:

Im laufenden Betrieb ist der Changierfadenführer 1 an den Permanentmagneten 12 angekoppelt und wird durch die Faden­führerstange 11 im Spulenbildungsbereich hin- und herbe­wegt. Nach Fertigstellung der Spule 21 - evtl. nach Still­setzen der Spule, Durchführung einer Wartungsarbeit an einer dieser Spulstelle zugeordneten Spinnstelle und erneutem Anspinnen des Fadens - wird die Spule 21 soweit angehoben, daß sie den Kontakt mit der Treibtrommel 3 verliert, und der umsteuerbare Motor 42 aktiviert, der die Gewindespindel 41 in Drehung setzt. Dadurch wird das durch eine Auflaufschräge 45 (Fig. 2) in die Stellung 4ʹ verschwenkte Verschiebemittel 4 in Richtung des Pfeiles P zum ortsfesten Anschlag 43 bewegt, wobei es den Changierfadenführer 1 vom Permanentmagneten 12 abdrückt und ihn mit dem im Fadenführer verbleibenden Faden auf der Fadenführerstange 11 über das Hülsenende hinaus in die Stellung 1ʹ in der Fadenklemm- und -schneidzone ver­schiebt. In dieser Stellung 1ʹ drückt der Changierfadenführer 1 die Feder 44 zusammen. Die Schwenkung des Verschiebemittels 4 in die Stellung 4ʹ erfolgt selbstverständlich dann, wenn sich der Changierfadenführer 1 in bezug auf die Verschiebe­richtung P vor dem Verschiebemittel 4 befindet. Um Fadenab­schläge von der Spule 21 beim Verschieben des Changierfaden­führers 1 über das Spulenende hinaus zu verhindern, wird vor oder gleichzeitig mit Beginn der Verschiebung die Fadenführer­gabel 8 in den Fadenweg geschwenkt. Der Faden legt sich in die Gabel 8 und ist so gegen ein Abrutschen von der Spule 21 gesichert.During operation, the traversing thread guide 1 is coupled to the permanent magnet 12 and is moved back and forth in the bobbin formation area by the thread guide rod 11. After completion of the bobbin 21 - possibly after the bobbin has been stopped, maintenance work has been carried out on a spinning station assigned to this bobbin and the thread is spun again - the bobbin 21 is raised to such an extent that it loses contact with the drive drum 3 and the reversible motor 42 activated, which sets the threaded spindle 41 in rotation. Characterized that by a ramp 45 (Fig. 2) in the position 4ʹ pivoted displacement means 4 is moved in the direction of arrow P to the fixed stop 43, it pushes the traversing thread guide 1 from the permanent magnet 12 and it with the thread remaining in the thread guide on the thread guide rod 11 moves beyond the end of the sleeve into position 1ʹ in the thread clamping and cutting zone. In this position 1ʹ the traversing thread guide 1 compresses the spring 44. The pivoting of the displacement means 4 in the position 4ʹ takes place, of course, when the traversing thread guide 1 is in front of the displacement means 4 in relation to the displacement direction P. In order to prevent thread strikes from the bobbin 21 when the traversing thread guide 1 is moved beyond the end of the bobbin, the thread guide fork 8 is pivoted into the thread path before or simultaneously with the start of the displacement. The thread lies in the fork 8 and is thus secured against slipping off the bobbin 21.

In der Endstellung 1ʹ befindet sich der Changierfadenführer 1 mit dem Faden dicht vor der Mündung des Saugrohres 9, das in die Stellung 9ʹ geschwenkt wurde. Der von der Spinn­vorrichtung bei stillstehender Spule 21 kontinuierlich weiter­gelieferte Faden wird in Form einer Schlaufe in das Saug­rohr 9 eingesaugt und durch eine nicht gezeigte Schneid­ vorrichtung, die zweckmäßig im Saugrohr 9 angeordnet ist, von der Spule 21 abgetrennt. Die Spule 21 wird nun gegen eine leere Spulenhülse ausgewechselt und diese an der Treib­trommel 3 zur Anlage gebracht.In the end position 1ʹ is the traversing thread guide 1 with the thread close to the mouth of the suction pipe 9, which has been pivoted into the position 9ʹ. The thread continuously supplied by the spinning device when the bobbin 21 is at a standstill is sucked into the suction tube 9 in the form of a loop and is cut by a not shown device, which is suitably arranged in the intake manifold 9, separated from the coil 21. The coil 21 is now exchanged for an empty bobbin tube and this is brought into contact with the drive drum 3.

Nach dem Aufsetzen der Spulenhülse auf die Treibtrommel 3 wird das Saugrohr 9 mit dem ständig abgesaugten Faden wieder aus der Ansaugstellung 9ʹ in die Ausgangsstellung zurück­geschwenkt (Figur 2). Durch diese Schwenkbewegung gelangt der Faden im Abschnitt zwischen dem Changierfadenführer 1 und der Mündung des Saugrohres 9 in die Ringnut 61 der mit der Spulenhülse umlaufenden Baueinheit 6 und schließ­lich in die Nut 52 des Bolzens 51 der Klemm- und Schneid­vorrichtung 5. Sobald der Faden in der Nut 52 liegt, wird der Bolzen 51 mittels der Druckstange 62 in der Bohrung 7 verschoben und der Faden durch die gegen den Rand 71 der Bohrung stoßende Schneidkante 53 abgeschnitten und durch die Klemmkante 54 festgeklemmt. Um die Verschiebung des Bolzens 51 genau zu dem Zeitpunkt zu bewirken, an dem sich der Faden in der Nut 52 befindet, wird die Stellung der Schneid- und Klemmeinrichtung 5 durch einen Initiator (nicht gezeigt) abgefragt und die Betätigung der Druckstange 62 nach einer von der Umfangsgeschwindigkeit des Bauteiles 6 anhängigen Zeit durch einen Zeitschalter (nicht gezeigt) ausgelöst. Der Bolzen 51 wird duruch eine Sperre in Form eines durch eine Feder 57 belasteten Schiebers 58 an der Rückbewe­gung in die Ruhestellung gehindert, so daß der Faden geklemmt bleibt (Fig. 5). Die Feder 57 drückt den Schieber 58 radial nach außen, wobei er in eine Nut 59 im Fortsatz 55 des Bol­zens 51 einrastet und aus dem Bauteil 6 herausragt.After the bobbin tube has been placed on the drive drum 3, the suction tube 9 is pivoted back with the thread continuously sucked out of the suction position 9 'into the starting position (FIG. 2). This pivoting movement of the thread in the section between the traversing thread guide 1 and the mouth of the suction tube 9 into the annular groove 61 of the assembly 6 rotating with the bobbin tube and finally into the groove 52 of the bolt 51 of the clamping and cutting device 5. As soon as the thread in the Groove 52 lies, the bolt 51 is moved by means of the push rod 62 in the bore 7 and the thread is cut by the cutting edge 53 abutting against the edge 71 of the bore and clamped by the clamping edge 54. In order to effect the displacement of the bolt 51 exactly at the point in time at which the thread is in the groove 52, the position of the cutting and clamping device 5 is queried by an initiator (not shown) and the actuation of the push rod 62 after one of the peripheral speed of the component 6 pending time triggered by a timer (not shown). The bolt 51 is prevented from moving back into the rest position by a lock in the form of a slide 58 loaded by a spring 57, so that the thread remains clamped (FIG. 5). The spring 57 presses the slide 58 radially outwards, wherein it engages in a groove 59 in the extension 55 of the bolt 51 and protrudes from the component 6.

Gleichzeitig mit dem Festklemmen des Fadens wird der die Gewindespindel 41 antreibende Motor 42 umgesteuert, so daß sich das Verschiebemittel 4 entgegen der Richtung des Pfei­les P zurückbewegt. Dabei drückt die Druckfeder 44 den Chan­gierfadenführer 1 ebenfalls in diese Richtung, der damit den Faden in den Spulbereich, zunächst jedoch in die radiale Ebene der Fadenreservebildung auf der Spulenhülse 2 zurück­führt. Die Fadenreserve wird zweckmäßig in der Weise ge­bildet, daß ein Längsstück des geklemmt gehaltenen Fadens außerhalb des Spulbereiches von der Reservewicklung über­wunden wird. Hierzu wird der die Gewindespindel 41 antrei­bende Motor 42 entsprechend umgesteuert.Simultaneously with the clamping of the thread, the motor 42 driving the threaded spindle 41 is reversed so that the displacement means 4 moves back against the direction of the arrow P. The compression spring 44 also presses the traversing thread guide 1 in this direction, which thus returns the thread into the winding area, but initially into the radial plane of the thread reserve formation on the bobbin tube 2. The thread reserve is expediently formed in such a way that a longitudinal piece of the thread held clamped is overcome by the reserve winding outside the winding area. For this purpose, the motor 42 driving the threaded spindle 41 is reversed accordingly.

Nach Fertigstellung der Reservewicklung schwenkt der Hub­magnet 64 den Hebel 63 um die Achse 65 in die in Fig. 4 gezeigte Lage, in der die Rolle 66 den Schieber 58 wieder entgegen der Kraft der Feder 57 in seine Ruhestellung zurück­drückt. Die Klemmung des Fadens im Bauteil 6 ist damit auf­gehoben und die Fadenführergabel 8 wird in ihre Ruhestellung zurückgeschwenkt. Ebenso wird das Verschiebemittel 4 vom Changierfadenführer 1 weg in die Ruhestellung geschwenkt. Die Verschwenkung erfolgt zweckmäßig, wenn sich der auf der Fadenführerstange 11 befestigte Permanentmagnet 12 dem Chan­gierfadenführer 1 nähert. Der Changierfadenführer koppelt, unterstützt durch die Rückstellkraft der Druckfeder 44, am Permanentmagneten 12 an und die Spulenbildung beginnt.After completion of the reserve winding, the lifting magnet 64 pivots the lever 63 about the axis 65 into the position shown in FIG. 4, in which the roller 66 pushes the slide 58 back into its rest position against the force of the spring 57. The clamping of the thread in component 6 is thus released and the thread guide fork 8 is pivoted back into its rest position. Likewise, the displacement means 4 is pivoted away from the traversing thread guide 1 into the rest position. The pivoting is expedient when the permanent magnet 12 fastened on the thread guide rod 11 approaches the traversing thread guide 1. The traversing thread guide, supported by the restoring force of the compression spring 44, couples to the permanent magnet 12 and the bobbin formation begins.
