Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Einführen von mindestens zwei Fäden und dergleichen in eine Spulvorrichtung

  • mit einer der Anzahl Fäden entsprechenden Anzahl axial nebeneinander angeordneten Changiervorrichtungen und
  • einer gleichen Anzahl sich auf einem Spulendorn befindlichen Spulenhülsen mit je einem Fadenfangmittel, z. B. einem Fangschlitz sowie
  • mit einer ersten Fadenführungsleiste oberhalb der Changiervorrichtungen, welche die Fäden beim Einführen ausser Eingriff mit diesen hält, und
  • pro Faden einem sich unterhalb der Changiervorrichtung befindlichen Fadenführer, welcher aus einer Ausgangslage am äusseren Ende des Spulendorns in einer Bewegungsrichtung parallel zum Spulendorn in eine innere Lage verschiebbar ist, in welcher der Faden vor das entsprechende Fadenfangmittel gebracht wird und welcher in dieser inneren Lage zum Versetzen der Fäden aus der Lage vor den Fadenfangmitteln in die Fangmittel schwenkbar ist.
The invention relates to a device for inserting at least two threads and the like into a winding device
  • with a number corresponding to the number of threads axially arranged traversing devices and
  • an equal number of bobbin tubes located on a spool, each with a thread catcher, e.g. B. a catch slot as well
  • with a first thread guide bar above the traversing devices, which keeps the threads out of engagement with them during insertion, and
  • per thread one thread guide located below the traversing device, which can be moved from a starting position at the outer end of the spool mandrel in a direction of movement parallel to the spool mandrel into an inner position in which the thread is brought in front of the corresponding thread catcher and which in this inner position is displaced the threads can be pivoted from the position in front of the thread catching means into the catching means.

Das Nebeneinanderreihen und doppelstöckige Aufeinanderstellen von Spulmaschinen einerseits und das mehrfädige Aufspulen andererseits sowie der Bedarf, alle Fäden gefahrlos und gleichzeitig allen Spulenhülsen zu übergeben, um gleichmässige Spulengewichte zu erhalten, verlangte einen Ersatz der manuellen Einzelfadenübergabe.The side-by-side and two-tier stacking of winding machines on the one hand and the multi-thread winding on the other hand as well as the need to hand over all threads safely and at the same time to all bobbin tubes in order to obtain uniform bobbin weights required a replacement of the manual single-thread transfer.

Aus der deutschen Offenlegungsschrift 26 27 643 ist eine Vorrichtung gemäss dem Oberbegriff des Patentanspruchs 1 bekannt.A device according to the preamble of claim 1 is known from German Offenlegungsschrift 26 27 643.

In dieser Vorrichtung werden die von einer Fadenführung oder einem Lieferwerk angelieferten Fäden mittels einer manuellen Fadenabsaugvorrichtung übernommen, anschliessend an einer Fadenleitstange stirnseitig vor der Spulvorrichtung mittels Führungskerben gemeinsam als Bündel, jedoch getrennt voneinander geführt. Anschliessend werden bei gleichzeitigem Bewegen der Fäden durch den Einführungsspalt der Spulvorrichtung, diese mittels längs der Tragachse der Spulenhülsen bewegbaren, die Fäden übernehmenden Fadenösen, voneinander auf einen, dem der in einer Reihe angeordneten Spulenhülsen entsprechenden Abstand vor diese gebracht.In this device, the threads supplied by a thread guide or a delivery system are taken over by means of a manual thread suction device, then on a thread guide rod on the front side of the winding device by means of guide notches together as a bundle, but guided separately from one another. Subsequently, when the threads are simultaneously moved through the insertion gap of the winding device, these are moved from one another to the one corresponding to the distance corresponding to the arranged in a row of bobbin tubes by means of the thread eyelets movable along the supporting axis of the bobbin tubes.

Anschliessend wird ein die Fadenösen tragender Schwenkbalken für das gleichzeitige Einlegen der Fäden in die Fangschlitze der Hülsen gegen, respektive unter die Spulenhülsen geschwenkt.Subsequently, a swivel bar carrying the thread eyelets is pivoted against or under the bobbin sleeves for the simultaneous insertion of the threads into the catch slots of the sleeves.

Gleichzeitig mit dem Bewegen der Fadenösen werden die Fäden aus den Führungskerben der Fadenleitstange gehoben, damit sie sich frei der Fadenleitstange entlang in die der Fadenspannung entsprechende Lage begeben können.Simultaneously with the movement of the thread eyelets, the threads are lifted out of the guide notches of the thread guide rod so that they can move freely along the thread guide rod into the position corresponding to the thread tension.

Das Bewegen der Fadenösen geschieht durch verschiebbare, die Fadenösen tragende Scheiben, die auf einer drehbaren Gewindespindel gelagert sind. Eine der Scheiben ist mit einem Innengewinde versehen und wird als Mutter (im weiteren Mutterscheibe genannt) von der sich drehenden Gewindespindel bewegt. Die übrigen Scheiben sind auf der Spindel gleitend verschiebbar angeordnet und untereinander durch Mitnehmerstangen verbunden.The thread eyelets are moved by displaceable disks which carry the thread eyelets and are mounted on a rotatable threaded spindle. One of the washers is provided with an internal thread and is moved as a nut (hereinafter referred to as the nut washer) by the rotating threaded spindle. The remaining disks are slidably arranged on the spindle and connected to one another by driver rods.

Die Nachteile der Vorrichtung liegen darin, dass die mögliche Ungenauigkeit der Scheibenrespektive der Fadenpositionen vor dem entsprechenden Fangschlitz durch eine zusätzliche Bewegung parallel zur Achse des Spulendornes kompensiert werden muss, um sicher zu sein, dass jeder Faden auch wirklich vom Fangschlitz erfasst wird. Die mögliche Ungenauigkeit entsteht einerseits durch die ungenaue Positionierung der Mutterscheibe durch den Drehzahlauslauf der motorgetriebenen Spindel und andererseits durch die Möglichkeit, dass die Reibung zwischen Mitnehmerstange und Scheibe grösser sein kann als zwischen Spindel und Scheibe.The disadvantages of the device are that the possible inaccuracy of the disk perspective of the thread positions in front of the corresponding catch slot has to be compensated for by an additional movement parallel to the axis of the bobbin mandrel in order to be sure that each thread is actually caught by the catch slot. The possible inaccuracy arises on the one hand from the imprecise positioning of the nut washer due to the speed of the motor-driven spindle and on the other hand from the possibility that the friction between the drive rod and the washer can be greater than that between the spindle and the washer.

Durch diesen Umstand entsteht auch der nachteilige Verfahrensschritt, dass die Fäden über die Positionen der Fangschlitze in Achsrichtung hinausbewegt und gemeinsam wieder zurückgeführt werden müssen, um sicher zu sein, dass die Fäden von den Fangschlitzen erfasst werden.This circumstance also creates the disadvantageous process step that the threads have to be moved beyond the positions of the catch slots in the axial direction and must be returned together to be sure that the threads are caught by the catch slots.

Diese Nachteile zu beheben ist Aufgabe der Erfindung. Die Erfindung, wie sie in Anspruch 1 gekennzeichnet ist, löst die Aufgabe derart,

  • dass die Fäden dadurch ausser Eingriff mit den Changiervorrichtungen gehalten werden, dass die erste Fadenführungsleiste aus einer Ruheposition in eine Arbeitsposition bewegbar ist,
  • dass unterhalb der ersten Führungsleiste eine zweite, mit Führungskerben versehene, aus einer Ruheposition in eine Arbeitsposition bewegbare Fadenführungsleiste vorgesehen ist, deren Anzahl Kerben der Anzahl aufzuwindender Fäden entspricht und bei welcher der gegenseitige Abstand (A) der Kerben den Abständen zwischen den Fadenfangmitteln entspricht,
  • dass ausserdem die Mittel für das Bewegen der ersten und zweiten Fadenführungsleiste und der Fadenführer derart gesteuert sind, dass vor dem Bewegen der Fadenführer aus der Ausgangslage gegen die innere Lage die erste Fadenführungsleiste aus der Ruhe- in die Arbeitsposition bewegt und anschliessend beim Bewegen der Fadenführer gegen die innere Lage die zweite Fadenführungsleiste dann aus der Ausgangsposition in die Arbeitsposition sowie die erste Fadenführungsleiste zurück in die Ruheposition bewegt wird, nachdem die Fadenführer so weit gegen die innere Lage bewegt wurden, dass jeder Faden von der entsprechenden Kerbe erfasst wurde, sowie dass, nachdem die Fäden von den .Fadenfangmittel übernommen wurden, die zweite Fadenführungsleiste derart eine Bewegung parallel zur Spulendornachse und zurück in die Ruheposition durchführt, dass die Fäden von der Changiervorrichtung erfasst werden,
  • dass im weiteren die Fadenführer je am freien Ende einer Fadenführerstange vorgesehen sind,
  • dass die Fadenführerstangen je an einem Trägerelement befestigt sind, welches gleitbar, aber verdrehfest und auf einer drehbaren Welle angeordnet ist, und
  • dass die Trägerelemente untereinander durch mit Anschlägen versehene Mitnehmerstangen verbunden sind, wobei eine genaue Positionierung dadurch erreicht wird, dass das der Lagerseite des Spulendornes nächstliegende innerste Trägerelement mittels eines Pneumatikzylinders antreibbar und zur Positionierung des ersten Trägerelementes ein Anschlag vorgesehen ist.
To solve these disadvantages is the object of the invention. The invention, as characterized in claim 1, achieves the object in such a way
  • that the threads are kept out of engagement with the traversing devices in that the first thread guide bar can be moved from a rest position into a working position,
  • that a second thread guide strip, provided with guide notches and movable from a rest position into a working position, is provided below the first guide strip, the number of notches of which corresponds to the number of threads to be wound and in which the mutual spacing (A) of the notches corresponds to the distances between the thread catching means,
  • that the means for moving the first and second thread guide strips and the thread guide are controlled in such a way that before the thread guide moves from the starting position against the inner position, the first thread guide strip moves from the rest position into the working position and then against when the thread guide is moved the inner layer, the second thread guide bar is then moved from the starting position into the working position and the first thread guide bar back to the rest position after the thread guides have been moved so far against the inner layer that each thread has been caught by the corresponding notch, and after that the threads have been taken over by the thread catching means, the second thread guide strip executes a movement parallel to the spool mandrel axis and back to the rest position such that the threads are gripped by the traversing device,
  • that the thread guides are always free End of a thread guide rod are provided,
  • that the thread guide rods are each fastened to a carrier element which is slidable but non-rotatable and arranged on a rotatable shaft, and
  • that the carrier elements are connected to one another by driver rods provided with stops, an exact positioning being achieved in that the innermost carrier element closest to the bearing side of the coil mandrel can be driven by means of a pneumatic cylinder and a stop is provided for positioning the first carrier element.

Weitere vorteilhafte Ausführungsformen der Erfindung sind in den weiteren Ansprüchen enthalten.Further advantageous embodiments of the invention are contained in the further claims.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass die Fäden zur Uebernahme durch die Fangschlitze der Spulenhülsen auf einfachere Weise genau und relativ zur axialen Richtung der Spulenhülsen stillstehend vor die Fangschlitze gebracht werden.The advantages achieved by the invention are essentially to be seen in the fact that the threads to be taken over by the catch slots of the bobbin tubes are brought in a simple manner precisely and relative to the axial direction of the bobbin tubes in a stationary manner in front of the catch slots.

The spool mandrel 4 can be moved from a moved-away position (rest position) (FIG. 1) to a raised position (working position) and back.

In der hochgefahrenen Position des Spulendornes liegen auf diesem festklemmbare Spulenhülsen 5 an der Reibwalze 3 an und erhalten dadurch die gewünschte Drehzahl und Drehrichtung. An den Spulenhülsen 5 ist je ein Fangschlitz 6 zum Festklemmen eines darin gefangenen Fadens 64a-d vorgesehen.In the raised position of the spool, these clampable spool sleeves 5 rest on the friction roller 3 and thereby obtain the desired speed and direction of rotation. A catch slot 6 is provided on the bobbin tubes 5 for clamping a thread 64a-d caught therein.

The tension spring 13 is between a support part 7a and the guide bar 8 clamped. The piston head 14 of the piston 11 bears against the end face 15 of the guide bar 8.

Unterhalb der Führungsleiste 8 ist eine zweite Führungsleiste 16 mittels eines am Supportteil 7b befestigten Lagerbocks 17 und einer darin dreh-und verschiebbar gelagerten sowie mit der Führungsleiste 8 verbundenen Welle 22 schwenk-und verschiebbar gelagert.Below the guide bar 8, a second guide bar 16 is pivotally and slidably mounted by means of a bearing block 17 fastened to the support part 7b and a shaft 22 which is rotatably and displaceably mounted therein and which is connected to the guide bar 8.

Die kombinierte Schwenk- und Verschiebebewegung, respektive Drallbewegung der Führungsleiste 16 wird durch die Drallbewegung einer mit der Welle 22 fest verbundenen Nutenwalze 20 ermöglicht, bei der ein mit einem Supportteil 7c verbundener Nutenstein 24 in eine Nute 23 der Nutenwalze 20 greift.The combined pivoting and shifting movement, or swirl movement of the guide bar 16 is made possible by the swirl movement of a grooved roller 20 firmly connected to the shaft 22, in which a sliding block 24 connected to a support part 7c engages in a groove 23 of the grooved roller 20.

Die Drallbewegung der Führungsleiste 16 aus einer Arbeitsposition (Fig. 4) in eine Ausgangsposition R (Fig. 4) entsteht durch die Spannkraft einer sich zwischen Lagerbock 17 und Nutenwalze 20 befindlichen Feder 21.The swirl movement of the guide bar 16 from a working position (FIG. 4) into an initial position R (FIG. 4) is caused by the tensioning force of a spring 21 located between the bearing block 17 and the grooved roller 20.

Die Drallbewegung der Führungsleiste 16 in umgekehrter Richtung, d. h. aus der Ruheposition in die Arbeitsposition, entsteht durch die Kraft eines Pneumatik-Kolbens 18, dessen Zylinder 19 am Support 7 befestigt (nicht gezeigt) ist.The swirl movement of the guide bar 16 in the reverse direction, i. H. from the rest position into the working position, is created by the force of a pneumatic piston 18, the cylinder 19 of which is attached to the support 7 (not shown).

Dementsprechend macht die Führungsleiste 16 beim Wechsel aus der Arbeitsposition in die Ruheposition eine Rückwärtsbewegung in Richtung Pneumatik-Zylinder 19.Accordingly, the guide bar 16 makes a backward movement in the direction of the pneumatic cylinder 19 when changing from the working position to the rest position.

Der Kolbenkopf 26 liegt an einer der Feder 21 gegenüberliegenden Stirnseite 25 der Nutenwalze 20 an.The piston head 26 rests on an end face 25 of the grooved roller 20 opposite the spring 21.

Die Fadenführungsleiste 16 hat in gleichen Abständen A vier Führungskerben 27a, 27b, 27c und 27d. Diese Abstände entsprechen den gegenseitigen Abständen der Fangschlitze 6 der auf dem Spulendorn 4 festgeklemmten Hülsen 5.The thread guide bar 16 has four guide notches 27a, 27b, 27c and 27d at equal intervals A. These distances correspond to the mutual distances between the catch slots 6 of the sleeves 5 clamped on the mandrel 4.

Unterhalb der beiden Führungsleisten sind die an sich im allgemeinen bekannten Changiervorrichtungen 28 (Fig. 4, in Fig. 2 andeutungsweise gezeigt) mit den Changierfadenführern 29 (Fig. 4), die in ihrem Changierbereich in an sich bekannter Weise den Faden für die Wickelbildung auf der Spulenhülse hin- und herführen, angeordnet.Below the two guide strips are the generally known traversing devices 28 (FIG. 4, shown in FIG. 2) with the traversing thread guides 29 (FIG. 4), which in their traversing area in a manner known per se are the thread for winding formation the coil sleeve back and forth, arranged.

Unterhalb dieser Changiervorrichtung 28 ist im weiteren eine Fadenführer-Verschiebe- und Schwenkvorrichtung 30 (Fig. 6) vorgesehen. Diese Vorrichtung 30 umfasst eine Welle 31, die einerseits in einem im Gehäuseteil 1a eingelassenen Lager 32 und in einem im Supportteil 7d eingelassenen Lager 33 drehbar gelagert ist.Below this traversing device 28, a thread guide displacement and swiveling device 30 (FIG. 6) is also provided. This device 30 comprises a shaft 31 which is rotatably supported on the one hand in a bearing 32 embedded in the housing part 1a and in a bearing 33 recessed in the support part 7d.

Um ein axiales Verschieben der Welle 31 zu vermeiden, ist die Welle 31 mit einem am Lager 32 stirnseitig anliegenden Bund 34 und das Lager 33 mit einem an der Welle 31 stirnseitig anliegenden Lagerdeckel 35 versehen.In order to avoid an axial displacement of the shaft 31, the shaft 31 is provided with a collar 34 abutting the end face of the bearing 32 and the bearing 33 is provided with a bearing cover 35 abutting the end face of the shaft 31.

Auf der Welle 31 sind gleitend Trägerelemente 36a bis 36d vorgesehen.Carrier elements 36a to 36d are slidably provided on the shaft 31.

In eine Vertiefung 37 des Trägerelementes 36a greift ein Mitnehmer 38 eines Pneumatik-Kolbens 39, dessen Zylinder 40 fest mit dem Gehäuseteil 1a verbunden ist. Im weiteren ist eine Mitnehmerstange 41 mit dem Trägerelement 36a fest und mit dem Trägerelement 36b reibschlüssig verbunden. Das Trägerelement 36c hat ebenfalls eine damit fest und mit dem Trägerelement 360 reibschlüssig verbundene Mitnehmerstange 42. Ausserdem ist eine mit dem Trägerelement 36d fest verbundene Mitnehmerstange 43 reibschlüssig mit dem Trägerelement 36c verbunden. Unter « reibschlüssig verbunden soll eine Gleitreibung von grosser Toleranz verstanden werden.A driver 38 of a pneumatic piston 39, the cylinder 40 of which is firmly connected to the housing part 1a, engages in a recess 37 of the carrier element 36a. In addition, a driver rod 41 is fixed to the carrier element 36a and connected to the carrier element 36b in a friction-locked manner. The carrier element 36c likewise has a driver rod 42 which is fixedly connected to it and frictionally connected to the carrier element 360. In addition, a driver rod 43 which is fixedly connected to the carrier element 36d is frictionally connected to the carrier element 36c. “Frictional connection” should be understood to mean sliding friction of great tolerance.

Je eine Fadenführerstange 44 ist am entsprechenden Trägerelement 36a, 36b, 36c und 36d befestigt und trägt je einen Fadenführer 45 (Fig. 4, 6 und 12).Each thread guide rod 44 is fastened to the corresponding carrier element 36a, 36b, 36c and 36d and carries a thread guide 45 (FIGS. 4, 6 and 12).

Beim Fadenführer 45 bildet eine Fadenleitkante 46 mit einer zweiten Fadenleitkante 46a eines Fingers 47 eine Führungskerbe 67 mit einem Winkel a von 90°; während bei einem Fadenführer 48 (Fig. 13), der als Variante für die Fadenführer 45 gewählt werden kann, die Führungskerbe 67 einen Winkel 9 von weniger als 90°, z. B. von 60°, aufweist. Die Anwendung dieser Variante wird später erwähnt.In the thread guide 45, a thread guide edge 46 with a second thread guide edge 46a of a finger 47 forms a guide notch 67 with an angle a of 90 °; while with a thread guide 48 (FIG. 13), which can be selected as a variant for the thread guide 45, the guide notch 67 has an angle 9 of less than 90 °, e.g. B. of 60 °. The use of this variant will be mentioned later.

Die Trägerelemente 36a bis 36d, die Fadenführerstangen 44 und die Fadenführer 45 bilden zusammen die Fadenführerelemente 51a, 51b, 51c und 51d.The carrier elements 36a to 36d, the thread guide rods 44 and the thread guide 45 together form the thread guide elements 51a, 51b, 51c and 51d.

Im weiteren hat die Welle 31 eine Längsnut 49 zur reibschlüssigen Aufnahme der in den entsprechenden Trägerelementen 36a, 36b, 36c und 36d befestigten Nutensteine 50. Dadurch werden die Fadenführerelemente 51a-d beim Drehen der Welle 31 geschwenkt.Furthermore, the shaft 31 has a longitudinal groove 49 for frictionally receiving the slot nuts 50 fastened in the corresponding carrier elements 36a, 36b, 36c and 36d. As a result, the thread guide elements 51a-d are pivoted when the shaft 31 is rotated.

Weiter ist ein Gleitbolzen 52 (Fig. 6) im Supportteil 7d befestigt und dient zur reibschlüssigen Aufnahme eines Mitnehmers 53, der seinerseits reibschlüssig in eine Nute 54 des Trägerelementes 36d greift. Ein Anschlag 55 am Ende des Gleitbolzens 52 dient mit Hilfe des Mitnehmers 53 zur Begrenzung der axialen Bewegung des Trägerelementes 36d. Im weiteren ist eine Zugfeder 56 zwischen dem Supporteil 7d und dem Mitnehmer 53 eingespannt.Furthermore, a slide pin 52 (FIG. 6) is fastened in the support part 7d and serves for frictionally receiving a driver 53, which in turn engages in a groove 54 of the carrier element 36d with a friction fit. A stop 55 at the end of the sliding bolt 52 is used with the aid of the driver 53 to limit the axial movement of the carrier element 36d. Furthermore, a tension spring 56 is clamped between the support part 7d and the driver 53.

Zum Drehen der Welle 31 dient ein Kurbeltrieb (Fig. 6 und 11), bestehend aus einem an einem Gehäuseteil 1 b schwenkbar angeordneten zweistufigen (nicht gezeigt) Pneumatik-Zylinder 58, einem Gelenkbolzen 60 für die Kraftübertragung zwischen einem am Kolbenende befestigten Gelenkteil 61 und einem am Wellenende 62 der Welle 31 befestigten Gelenkteil 63.A crank mechanism (FIGS. 6 and 11) is used to rotate the shaft 31, consisting of a two-stage pneumatic cylinder 58 (not shown) pivotably arranged on a housing part 1b, a hinge pin 60 for the power transmission between a hinge part 61 and fixed to the piston end a joint part 63 fastened to the shaft end 62 of the shaft 31.

Das Einführen von Fäden 64a, 64b, 64c und 64d in die Spulvorrichtung 2 ist anhand der Fig. 1 und 4 gezeigt und geschieht folgendermassen :The introduction of threads 64a, 64b, 64c and 64d into the winding device 2 is shown with reference to FIGS. 1 and 4 and takes place as follows:

1. Phase1st phase

Von Fadenführern 65 oder einem Lieferwerk (nicht gezeigt) herkommende Fäden 64a-d (Fig. 1) werden mittels einer sogenannten Saugpistole 66 oder einer funktionell äquivalenten Saugvorrichtung, z. B. einer automatischen Saugvorrichtung (nicht gezeigt) angesaugt, an die in Arbeitsposition gebrachte (in Fig. 4 mit ausgezogener Linie gezeigt) erste Fadenführungsleiste 8 und in die Fadenführer 45, respektive Führungskerben 67, geführt.Threads 64a-d (FIG. 1) coming from thread guides 65 or a delivery mechanism (not shown) are so-called by means of a so-called suction gun 66 or a functionally equivalent suction device, e.g. B. an automatic suction device (not shown), to the brought into the working position (shown in Fig. 4 with a solid line) first thread guide 8 and in the thread guide 45, respectively guide notches 67, out.

Die Fadenführer 65 bilden den Scheitelpunkt des Changierdreiecks und sind im wesentlichen senkrecht über der Mitte des Changierbereiches jeder Spulenhülse 5 angeordnet, wie es in Fig. 1 andeutungsweise an einer Hülse mit dem Bereich C gezeigt ist.The thread guides 65 form the apex of the traversing triangle and are arranged essentially perpendicularly above the center of the traversing area of each bobbin tube 5, as is indicated in FIG. 1 on a tube with the area C.

Vor dem manuellen Einführen der Fäden 64a bis 64d in die entsprechenden Fadenführer 45 wurden die Fadenführerelemente 51a bis 51d d mittels der ersten Stufe des Pneumatik-Zylinders 58, aus einer Ausgangsposition D in eine Fadenaufnahmeposition E geschwenkt (Fig. 4 und 6).Before the manual introduction of the threads 64a to 64d into the corresponding thread guide 45, the thread guide elements 51a to 51d d were pivoted from an initial position D into a thread take-up position E by means of the first stage of the pneumatic cylinder 58 (FIGS. 4 and 6).

Die Fäden liegen in dieser ersten Einführphase, wie in den Fig. 2 und 5 sowie in Fig. 4 mit ausgezogener Linie gezeigt, an der Führungsleiste 8, jedoch noch nicht an der ebenfalls bereits in die Arbeitsposition (in Fig. 4 dargestellt) gebrachten zweiten Fadenführungsleiste 16 an. Ausserdem sind in dieser Phase die Fäden, wie in Fig. 4 mit ausgezogener Linie dargestellt, von den Changierfadenführern 29 nicht erfassbar und liegen im Raum zwischen der Fadenführungsleiste 8 und den Fadenführern 45 frei gespannt.In this first insertion phase, as shown in FIGS. 2 and 5 and in FIG. 4 with a solid line, the threads lie on the guide bar 8, but not yet on the second one, which has also already been brought into the working position (shown in FIG. 4) Thread guide bar 16. In addition, in this phase, the threads, as shown in FIG. 4 with a solid line, cannot be detected by the traversing thread guides 29 and are freely tensioned in the space between the thread guide bar 8 and the thread guides 45.

2. Phase2nd phase

Aus Fig. 1, 2 und 5 ist ersichtlich, dass der Faden 64a, beim Verteilen der Fäden vor die entsprechenden Fangschlitze 6, erst dann der zweiten Fadenführungsleiste 16 übergeben werden darf, wenn er sich in der Position zwischen den Führungskerben 27b und 27a (Fig. 5) befindet. Aus diesem Grunde ist die zweite Phase, nämlich das Verteilen der Fäden 64a bis 64d vor die Fangschlitze 6 wie folgt gesteuert :

  • Auf Knopfdruck (nicht gezeigt) beginnt der Pneumatik-Zylinder 40 (Fig. 6) den Kolben 39 und damit die Fadenführungselemente 51a-d aus der in Fig. 1 gezeigten Ausgangslage in die in Fig. 3 gezeigte Lage zu verschieben. Etwas verzogert dazu wird durch Entlastung des Zylinders 12 (Fig. 5) die erste Fadenführungsleiste 8 mittels der Zugfeder 13 in Richtung 9b zurück in die Ausgangsposition B versetzt, so dass die Fäden 64a bis 64d auf der zweiten Führungsleiste 16 zur Anlage kommen. Dabei wird jeder Faden auf seinem noch auf dieser Führungsleiste zurückzulegenden Weg in der entsprechenden Führungskerbe 27a bis 27d angehalten, d. h. der Faden 64a in der Kerbe 27a, der Faden 64b in der Kerbe 27b, etc.
1, 2 and 5 it can be seen that the thread 64a, when distributing the threads in front of the corresponding catch slots 6, may only be transferred to the second thread guide strip 16 when it is in the position between the guide notches 27b and 27a (FIG 5). For this reason, the second phase, namely the distribution of the threads 64a to 64d in front of the catch slots 6, is controlled as follows:
  • At the push of a button (not shown), the pneumatic cylinder 40 (FIG. 6) begins to move the piston 39 and thus the thread guide elements 51a-d from the initial position shown in FIG. 1 to the position shown in FIG. 3. Slightly delayed to this end, by relieving the load on the cylinder 12 (FIG. 5), the first thread guide bar 8 is moved back in the direction 9b into the starting position B by means of the tension spring 13, so that the threads 64a to 64d come to rest on the second guide bar 16. Each thread is stopped on its path still to be covered on this guide bar in the corresponding guide notch 27a to 27d, ie the thread 64a in the notch 27a, the thread 64b in the notch 27b, etc.

Am Ende dieser zweiten Phase liegen die Fäden 64a-d wie in Fig. 3 gezeigt und in Fig. 4 mit gestrichelter Linie dargestellt innerhalb der Spulvorrichtung zwischen den Kerben 27a-d und den Fadenführern 45 frei gespannt neben dem Changierbereich C sowie genau vor den entsprechenden Fangschlitzen 6 und im wesentlichen parallel zu diesen.At the end of this second phase, the threads 64a-d, as shown in FIG. 3 and shown in FIG. 4 with a broken line, lie freely tensioned within the winding device between the notches 27a-d and the thread guides 45 next to the traversing area C and exactly in front of the corresponding ones Catch slots 6 and substantially parallel to them.

Die genaue Lage der Fäden vor den entsprechenden Fangschlitzen 6 ist durch die genaue Lage der Fadenführer 45 gewährleistet, deren Weg durch den Anschlag 53 sowie durch die an den Mitnehmerstangen 41, 42 und 43 vorgesehenen, an den Trägerelementen 36b und 36c anliegenden Anschlägen 41 a, 42a respektive 43a genau begrenzt ist.The exact position of the threads in front of the corresponding catch slots 6 is ensured by the exact position of the thread guides 45, their path through the stop 53 and through the stops 41 a provided on the driving rods 41, 42 and 43 and resting on the carrier elements 36b and 36c. 42a or 43a is precisely limited.

Ausserdem hält die Feder 56 das Trägerelement 36d so lange zurück, bis die anderen drei Trägerelemente ihre durch die Anschläge 41a, 42a, respektive 43a, gegebenen Abstände untereinander erreicht haben. Auf diese Weise gleitet der noch an der Leiste 8 anliegende Faden 64d auch dann noch nicht über die Kerbe 27d hinweg, wenn z. B. die Reibung zwischen Trägerelement und Mitnehmerstange grösser wäre als zwischen Trägerelement und Welle 31.In addition, the spring 56 retains the carrier element 36d until the other three carrier elements have reached their spacing from one another given by the stops 41a, 42a or 43a. In this way, the thread 64d still resting on the bar 8 does not slide over the notch 27d even when e.g. B. the friction between the carrier element and the driving rod would be greater than between the carrier element and the shaft 31.

3. Phase3rd phase

In dieser Phase wird mittels der zweiten Stufe des Pneumatik-Zylinders 58 die Welle 31 gedreht und damit die Fadenführerelemente 51a-d gemeinsam in die mit F bezeichnete Position geschwenkt. Dadurch gelangen die Fäden 64a-d in die entsprechenden Fangschlitze 6 und werden von der Saugpistole 66 abgerissen, so dass die Windungen sich zu bilden beginnen.In this phase, the shaft 31 is rotated by means of the second stage of the pneumatic cylinder 58 and thus the thread guide elements 51a-d are pivoted together into the position denoted by F. As a result, the threads 64a-d get into the corresponding catch slots 6 and are torn off by the suction gun 66, so that the windings begin to form.

Nach dem Erreichen der Position F durch die Fadenführungselemente 51 wird der Pneumatik-Zylinder 19 entlastet, so dass die Feder 21 die Nutenwalze 20 und damit die zweite Fadenführungsleiste 16 zurück in die Ausgangsposition R versetzt. Dabei wird die Führungsleiste 16 mittels der genannten Drallbewegung aus dem Fadenlauf weggeschwenkt. Während dieser Drallbewegung werden die Fäden durch die Kerben 27a-d derart geführt, dass zwischen Fangschlitz 6 und Changierbereich C einige Reservewindungen gelegt werden. Am Ende der Drallbewegung sind die Fäden 64 frei zwischen den Fadenführern 65 und den Hülsen 5 gespannt, streben infolge dieser Fadenspannung in den Changierbereich C, und werden durch die Changierfadenführer 29 erfasst. Mit dem Erfassen der Fäden durch die Changierfadenführer 29 beginnt der normale Aufwindvorgang.After the position F is reached by the thread guide elements 51, the pneumatic cylinder 19 is relieved, so that the spring 21 moves the grooved roller 20 and thus the second thread guide strip 16 back to the starting position R. The guide bar 16 is pivoted away from the thread path by means of the swirl movement mentioned. During this twisting movement, the threads are guided through the notches 27a-d in such a way that some reserve turns are placed between the catch slot 6 and the traversing area C. At the end of the twisting movement, the threads 64 are stretched freely between the thread guides 65 and the sleeves 5, strive as a result of this thread tension in the traversing area C, and are gripped by the traversing thread guides 29. When the threads are gripped by the traversing thread guides 29, the normal winding process begins.

Eine weitere Ausgestaltung der Erfindung besteht darin, dass eine Fadenumlenkung 69 derart angeordnet ist (in Fig. 1 und 3 gestrichelt angedeutet), dass darin gebündelte und an der ersten Fadenführungsleiste 8, wie in Fig. 1 gezeigt, geführte Fäden 64a-d von den Fadenführern 45, beim Schwenken aus der Position D (Fig. 4) in die Position E erfasst werden.A further embodiment of the invention consists in that a thread deflection 69 is arranged (indicated by dashed lines in FIGS. 1 and 3) in such a way that threads 64a-d, bundled therein and guided on the first thread guide strip 8, as shown in FIG Thread guides 45 are detected when swiveling from position D (FIG. 4) to position E.

Diese Ausführung bietet den Vorteil, dass die Fäden 64 nicht einzeln von Hand in die entsprechenden Fadenführer 45 gelegt werden müssen, was eine weitere Vereinfachung des Verfahrens und eine weitere Zeitersparnis ergibt.This embodiment offers the advantage that the threads 64 do not have to be placed individually in the corresponding thread guides 45 by hand, which results in a further simplification of the method and a further time saving.

Das beschriebene Verfahren sowie die Vorrichtung ist ebenfalls für andere Fadenfangvorrichtungen anwendbar, die neben den Hülsen, z. B. am Spulendorn selbst, vorgesehen sind. Solche Vorrichtungen ersetzen die genannten Fangschlitze 6.The method described and the device can also be used for other thread catching devices which, in addition to the sleeves, e.g. B. on the mandrel itself are provided. Such devices replace the catch slots 6 mentioned.

Ein solcher Spulendorn ist z. B. aus der US-PS-4 106 711 und der GB-PS-1 562 548 bekannt.Such a mandrel is z. B. from US-PS-4 106 711 and GB-PS-1 562 548 known.

Die dritte Phase geht mit dem in den genannten Patentschriften gezeigten Spulendorn mit der konischen Fadenleitfläche 11 und den Zähnen 12 wie folgt vor sich :

  • Die Fadenführungselemente 51a-d bringen den entsprechenden Faden 64a-d beim Schwenken in die Position F an die entsprechende Fläche 11. Durch die bestehende, von der Saugpistole erzeugte Fadenspannung gleitet der Faden auf der Fläche 11 in den Bereich der Zähne 12 und wird, wie in den Patentschriften beschrieben, erfasst und abgeschnitten.
The third phase proceeds as follows with the bobbin mandrel with the conical thread guiding surface 11 and the teeth 12 shown in the aforementioned patents:
  • The thread guide elements 51a-d bring the corresponding thread 64a-d to the corresponding surface 11 when pivoted into the position F. Due to the existing thread tension generated by the suction gun, the thread slides on the surface 11 into the area of the teeth 12 and becomes like described, recorded and cut off in the patent specifications.

Die Lage einer Fläche 11 entlang des Spulendornes entspricht im wesentlichen der Lage eines Fangschlitzes 6.The position of a surface 11 along the coil mandrel essentially corresponds to the position of a catch slot 6.
