Description

Die Erfindung betrifft eine Spulmaschine für automatischen Spulenwechsel gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a winder for automatic bobbin changing according to the preamble of patent claim 1.

Bei einer Spulmaschine dieser Gattung, die durch die DE-AS 2 733 120 bekanntgeworden ist, sind zum Ausheben und Verlegen des Fadens beim Spulenwechsel oberhalb und unterhalb der Position des mit der neuen Hülse bestückten Spanndorns Fanghaken vorgesehen, die um annähernd senkrechte Achsen schwenkbar sind. Die Praxis hat gezeigt, daß dabei insbesondere infolge des Durchschwingens der Fanghaken die Fadenführung nicht genügend exakt ist. Daher ist nicht immer gewährleistet, daß auf der neuen Hülse das abgeschnittene Fadenende vom Anknotwickel überspult wird. Es hängt daher gelegentlich frei heraus und kann sich beim Spulenausstoß verfangen. Es kommt auch vor, daß derFaden beim Umlegen auf die neue Hülse seitlich von der vollen Hülse abgleitet.In a winding machine of this type, which has become known from DE-AS 2 733 120, hooks are provided for lifting and laying the thread when changing the bobbin above and below the position of the mandrel equipped with the new sleeve, which hooks can be pivoted about approximately vertical axes. Practice has shown that the thread guide is not sufficiently precise, particularly as a result of the catch hooks swinging through. Therefore, it is not always guaranteed that the cut end of thread will be spooled by the knot wrap on the new tube. It occasionally hangs freely and can get caught when the spool is ejected. It also happens that the thread slides laterally from the full tube when it is folded over onto the new tube.

Der Erfindung liegt die Aufgabe zugrunde, eine Spulmaschine gemäß dem Oberbegriff des Patentanspruchs 1 so zu verbessern, daß beim Spulenwechsel eine absolut exakte Fadenführung gewährleistet ist. Dadurch sollen die angegebenen unerwünschten Effekte vermieden werden.The invention has for its object to improve a winder according to the preamble of claim 1 so that an absolutely exact thread guidance is guaranteed when changing the bobbin. This is intended to avoid the specified undesirable effects.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale gelöst.This object is achieved by the features specified in the characterizing part of patent claim 1.

Die Ansprüche 2 und 3 beinhalten vorteilhafte konstruktive Ausgestaltungen der Erfindung.Claims 2 and 3 contain advantageous constructive refinements of the invention.

Die Zeichnung dient zur Erläuterung der Erfindung anhand eines vereinfacht dargestellten Ausführungsbeispiels.

  • Fig. 1 zeigt eine Seitenansicht einer Spulmaschine gemäß der Erfindung;
  • Fig. 2 zeigt eine Ansicht des Schlittens aus einer um 90° gedrehten Richtung, wobei die nicht erfindungswesentlichen Bauteile zur Verbesserung der Übersichtlichkeit weggelassen wurden.
The drawing serves to explain the invention with reference to an embodiment shown in simplified form.
  • Fig. 1 shows a side view of a winding machine according to the invention;
  • Fig. 2 shows a view of the carriage from a direction rotated by 90 °, wherein the components not essential to the invention have been omitted to improve clarity.

Die Spulmaschine besteht, wie bekannt, aus einem Gehäuse 1, einen an dem Gehäuse 1 um seine Achse 2 drehbar gelagerten Spulenrevolver 3 und einem Schlitten 4, der zwecks Anpassung an den jeweiligen Spulendurchmesser rechtwinklig zur Achse 2 hin und her beweglich ist, wie durch den Doppelpfeil 5 angedeutet.As is known, the winding machine consists of a housing 1, a coil turret 3 which is rotatably mounted on the housing 1 about its axis 2, and a slide 4 which can be moved back and forth at right angles to the axis 2 for adaptation to the respective coil diameter, as by the Double arrow 5 indicated.

Der Spulenrevolver 3 ist mit zwei einander diametral gegenüberliegenden Spanndornen 6, 7 bestückt, die zur Aufnahme von Spulenhülsen dienen. An dem der Lagerung benachbarten Ende der Spanndorne 6, 7 sind zwei einander diametral gegenüberliegende, hakenartig geformte Messer 8, 9 angebracht, die über den Rand der aufgesteckten Hülse 10 greifen. Dabei bildet die Messerhalterung den Anschlag für die Hülse 10. Der Einfachheit halber wurde für die Zeichnung ein Ausführungsbeispiel ausgewählt, bei dem auf jedem Spanndorn nur eine einzige Hülse bzw. Spule sitzt. Selbstverständlich ist es auch möglich, pro Spanndorn mehrere Hülsen nebeneinander unterzubringen. Entsprechend der vorgesehenen Zahl der Hülsen sind dann längs des Spanndorns mehrere Messer angebracht, die beim Spulenwechsel, wie in der bereits genannten DE-AS 2 733 120 beschrieben, in das Innere des Spanndorns 6, versenkbar sind.The coil turret 3 is equipped with two diametrically opposed mandrels 6, 7, which serve to receive coil sleeves. At the end of the mandrels 6, 7 adjacent to the bearing, two diametrically opposed, hook-shaped knives 8, 9 are attached, which grip over the edge of the attached sleeve 10. The knife holder forms the stop for the sleeve 10. For the sake of simplicity, an embodiment was selected for the drawing in which only a single sleeve or coil is seated on each mandrel. Of course, it is also possible to accommodate several sleeves next to each other for each mandrel. According to the intended number of sleeves, several knives are then attached along the mandrel, which can be lowered into the interior of the mandrel 6 when changing the spool, as described in DE-AS 2 733 120 already mentioned.

Auf dem Schlitten 4 ist über einer Andrückrolle 11 eine Changiereinrichtung 12 mit einem Changierfadenführer 13 angeordnet. Der Changierbereich ist durch die in Fig. erkennbaren strichpunktierten Linien 14, 15 begrenzt. Wie bekannt, endet der Changierbereich insbesondere an der dem Gehäuse 1 zugekehrten Seite in einem gewissen Abstand vom Rand der aufgesteckten Hülse 10. Der nicht von der Changierung überstrichene Endbereich der Hülse, d. h. der Bereich zwischen der Ebene der Messer 8, 9 und dem benachbarten Ende des Changierbereiches ist der sogenannte Anknotwickelbereich 16.A traversing device 12 with a traversing thread guide 13 is arranged on the carriage 4 above a pressure roller 11. The traversing range is limited by the dash-dotted lines 14, 15 shown in FIG. As is known, the traversing area ends, in particular on the side facing the housing 1, at a certain distance from the edge of the attached sleeve 10. H. the area between the level of the knives 8, 9 and the adjacent end of the traversing area is the so-called knot winding area 16.

Über dem Schlitten 4 ist in der Mitte des Changierbereiches ein feststehender Fadenführer, z. B. eine Öse, angebracht, der in der Zeichnung nicht dargestellt ist, da er relativ hoch liegt. Der Faden wird also bei dem dargestellten Ausführungsbeispiel von oben zugeführt. Selbstverständlich ist die Erfindung ebensogut auch bei Spulautomaten anwendbar, bei denen der Faden z. B. seitlich zuläuft. Zur Vereinfachung der Aus drucksweise wird in dieser Beschreibung und in den Patentansprüchen stets die Richtung, aus der der Faden einläuft, als »oben« bezeichnet. In dem entsprechenden Sinne sind auch die Worte »unten«, »über« usw. zu verstehen.Above the carriage 4 in the middle of the traversing area is a fixed thread guide, e.g. B. an eyelet attached, which is not shown in the drawing, since it is relatively high. The thread is thus fed from above in the illustrated embodiment. Of course, the invention is equally applicable to automatic winding machines in which the thread z. B. runs laterally. To simplify the printout, the direction from which the thread runs in is always referred to as "above" in this description and in the patent claims. In the corresponding sense, the words "below", "above" etc. are also to be understood.

An jeder Seite des Schlittens 4 ist eine annähernd senkrecht stehende Leiste 17 angebracht. In diesen beiden seitlichen Leisten sind zwei runde Führungsstangen 18, 19 gelagert, die eine oberhalb der Ebene der Achse des ihr zugekehrten Spanndorns 6, die andere unterhalb dieser Ebene. Mit den beiden Führungsstangen 18, 19 sind Bleche 20, 21 durch seitliche Halteplatten 22, 23 fest verbunden. Die Bleche 20, 21 greifen in der in Fig. 1 mit durchgezogenen Linien dargestellten, annähernd horizontalen Eingriffsstellung zangenartig, jedoch mit Abstand, um den mit einer leeren Hülse 10 bestückten Spanndorn 6.An approximately vertical bar 17 is attached to each side of the slide 4. Two round guide rods 18, 19 are mounted in these two lateral strips, one above the plane of the axis of the mandrel 6 facing it and the other below this plane. With the two guide rods 18, 19 sheets 20, 21 are firmly connected by lateral holding plates 22, 23. In the approximately horizontal engagement position shown in solid lines in FIG. 1, the sheets 20, 21 grip like pliers, but at a distance around the mandrel 6 equipped with an empty sleeve 10.

Die Halteplatten 22, 23 sind miteinander durch eine angelenkte Koppelstange 24 verbunden, und zwar so, daß das Gelenk 25 an der oberen Halteplatte 22 auf der einen Seite der durch die beiden Stangenachsen definierten Ebene liegt, das Gelenk 26 an der unteren Halteplatte 23 jedoch auf der anderen Seite dieser Ebene. Außerdem greift an der Halteplatte 22 der Kolben eines Zylinders 27 an, der an der Grundplatte des Schlittens 4 angelenkt ist. Durch Betätigung des Zylinders 27 lassen sich die beiden Bleche 20, 21 gleichzeitig in die mit strichpunktierten Linien angedeuteten, nahezu senkrechten Stellungen 20a, 21 a, zurückschwenken.The holding plates 22, 23 are connected to one another by an articulated coupling rod 24 in such a way that the joint 25 on the upper holding plate 22 lies on one side of the plane defined by the two rod axes, but the joint 26 on the lower holding plate 23 the other side of this level. In addition, the piston of a cylinder 27, which is articulated on the base plate of the slide 4, acts on the holding plate 22. By actuating the cylinder 27, the two sheets 20, 21 can simultaneously be pivoted back into the almost vertical positions 20a, 21a, indicated by dash-dotted lines.

Die Vorderkante 28 des oberen Bleches 20, das sich im wesentlichen über die ganze Länge des Spanndorns 6 erstreckt, verläuft parallel zu der Achse des Spanndorns 6. In der Eingriffsstellung liegt sie etwa in der Mitte über der Verbindungslinie zwischen dem Changierfadenführer 13 und der Achse des Spanndorns 6. Sie ist etwa in der Mitte des Anknotwickelbereichs 16 mit einem hakenartig vorspringenden Anschlag 29 versehen.The front edge 28 of the upper plate 20, which extends essentially over the entire length of the mandrel 6, runs parallel to the axis of the mandrel 6. In the engaged position, it lies approximately in the middle above the connecting line between the traversing thread guide 13 and the axis of the mandrel 6. It is provided with a hook-like projecting stop 29 approximately in the middle of the knot winding area 16.

Die Vorderkante 30 des unteren Bleches 21 verläuft ebenfalls parallel zur Achse des Spanndorns 6. Sie liegt etwa in der dem Schlitten 4 abgewandten senkrechten Tangentialebene des Spanndorns 6. Sie ist ebenfalls mit einem hakenartig vorspringenden Anschlag 31 versehen, der jedoch im Changierbereich liegt, und zwar nicht weit von der Mitte.The front edge 30 of the lower plate 21 also runs parallel to the axis of the mandrel 6. It lies approximately in the vertical tangential plane of the mandrel 6 facing away from the carriage 4. It is also provided with a hook-like projecting stop 31, which, however, lies in the traversing area, specifically not far from the middle.

Zwischen den beiden Stangen 18, 19 ist ein Zylinder 32 mit einer Kolbenstange 33 angeordnet, die eine Traverse 34 trägt. Auf den beiden zu den Stangen 18,19 reichenden Enden der Traverse 34 sind je zwei Ringe 35, 36, 37, 38 befestigt, der eine 35, 37 auf der einen Seite der Traverse, der andere 36, 38 auf der anderen Seite. Die Ringe sitzen auf den Stangen 18, 19 und sind relativ zu diesen in Längsrichtung beweglich, jedoch unverdrehbar.Between the two rods 18, 19 there is a cylinder 32 with a piston rod 33 which carries a cross member 34. Two rings 35, 36, 37, 38 are fastened to each of the two ends of the crossmember 34 reaching the rods 18, 19, one 35, 37 on one side of the crossmember, the other 36, 38 on the other side. The rings sit on the rods 18, 19 and are movable relative to them in the longitudinal direction, but non-rotatable.

An dem Ring 36, der auf der oberen Stange 18 in Fig. 2 rechts von der Traverse 34 sitzt, ist ein Finger 39 befestigt. In ähnlicher Weise ist auf dem Ring 37, der auf der unteren Stange 19 in Fig. 2 links von der Traverse, d. h. also schräg versetzt zu dem Finger 39, sitzt, ein Finger 40 befestigt. Die Finger 39, 40 sind rechtwinklig zu den Stangen 18, 19 angeordnet, erstrecken sich in der Eingriffsstellung annähernd waagerecht vom Schlitten 4 in Richtung auf den Revolver 3 und reichen mit ihren freien Enden bis über die Kanten 28, 30 hinaus. Beim Zurückschwenken der Bleche 20, 21 in die Ruhelage 20a, 21 a behalten die Finger 39, 40 wegen ihrer relativ zu den Stangen 18, 19 unverdrehbaren Anordnung ihre relative Lage zu den Blechen 20, 21 bei, d. h. die freien Enden der Finger 39, 40, insbesondere das des oberen Fingers, befinden sich in kurzem Abstand vor den Kanten 28, 30.A finger 39 is attached to the ring 36, which sits on the upper rod 18 in FIG. 2 to the right of the cross member 34. Similarly, on the ring 37 which is on the lower rod 19 in Fig. 2 to the left of the crossbar, i. H. that is, at an angle to the finger 39, is seated, a finger 40 is attached. The fingers 39, 40 are arranged at right angles to the rods 18, 19, extend in the engagement position approximately horizontally from the slide 4 in the direction of the turret 3 and extend with their free ends beyond the edges 28, 30. When the sheets 20, 21 are pivoted back into the rest position 20a, 21a, the fingers 39, 40 maintain their relative position to the sheets 20, 21 because of their non-rotatable arrangement relative to the rods 18, 19. H. the free ends of the fingers 39, 40, in particular that of the upper finger, are located a short distance from the edges 28, 30.

Im normalen Wickelbetrieb sind die Bleche 20, 21 und die Finger 39, 40 in der zurückgeklappten Stellung, in der sie keine Funktion haben. Wie in Fig. 2 mit strichpunktierten Linien angedeutet, sind dabei die Finger 39, 40 über die Mitte des Changierbereiches hinaus zurückgefahren. Wenn die im Betrieb in Fig. 1 links befindliche Spule voll ist, schwenkt der Revolver 3 in Richtung des Pfeiles 41 um 180°, so daß die volle Spule nach rechts gelangt. Sie ist in dieser Stellung durch die Kreislinie 42 angedeutet. Der Schlitten 4 bewegt sich in Richtung auf die noch leere Spulenhülse 10 des anderen Spanndorns, der jetzt in die Betriebsstellung eingeschwenkt ist. Der um die leere Hülse 10 herumgeführte Faden 43 wird zunächst noch weiter bei weiterlaufender Changierung auf die volle Spule gewickelt. Dann klappen die Bleche 20, 21 und die mit ihnen verbundenen Finger 39, 40 in die Eingriffsstellung. Das obere Blech 20 berührt mit seiner als Führungsschiene ausgebildeten Vorderkante 28 den Faden 43 und hebt ihn aus dem-Changierfadenführer 13. Infolgedessen bewegt sich der Faden - gleichgültig an welcher Stelle er aus dem Changierfadenführer ausgehoben worden ist - zur Mitte des Changierbereiches hin. Die Vorderkante 30 des unteren Bleches 21 berührt ebenfalls den Faden. Durch Beaufschlagung des Zylinders 32 bewegen sich die Finger 39, 40 aus ihrer Ruhestellung synchron in Richtung auf das Ende der Hülse 10, an dem die Messer 8, angeordnet sind. Dadurch wird der Faden 43 an den Führungsschienen 28, 30 entlanggeführt. Der obere Finger 39 fährt bis zu dem Anschlag 29. Der Faden ist bei dieser Stellung mit geringem Spielraum in einer engen Öffnung exakt geführt. Infolge der versetzten Anordnung der Finger 39, 40 fährt der untere Finger 40 etwas weiter, und zwar bis über die Messer 8, 9 und das Ende der Hülse 10 hinaus. Das um die Hülse 10 herumgeführte Fadenstück läuft daher schräg zum Rand der Hülse. Dabei liegt es im oberen Bereich auf der Hülse auf und geht im unteren Bereich über den Hülsenrand hinaus, wobei es die Ebene durchdringt, in der die Messer 8, 9 umlaufen. Dabei wird durch den Anschlag 31 des unteren Bleches 21 der Faden 43 in sicherem Abstand von der Kante der vollen Spule 42 gehalten, so daß er keinenfalls von der Kante abrutschen kann.In normal winding operation, the sheets 20, 21 and the fingers 39, 40 are in the folded-back position in which they have no function. As indicated by dash-dotted lines in FIG. 2, the fingers 39, 40 are moved back beyond the center of the traversing area. When the spool on the left in operation in FIG. 1 is full, the turret 3 pivots through 180 ° in the direction of arrow 41, so that the full spool reaches the right. In this position it is indicated by the circular line 42. The carriage 4 moves in the direction of the still empty spool sleeve 10 of the other mandrel, which is now pivoted into the operating position. The thread 43 which is guided around the empty tube 10 is initially wound even further as the traversing continues on the full bobbin. Then the sheets 20, 21 and the fingers 39, 40 connected to them fold into the engagement position. The upper plate 20 touches the thread 43 with its front edge 28, which is designed as a guide rail, and lifts it out of the traversing thread guide 13. As a result, the thread moves to the center of the traversing region, irrespective of the point at which it was lifted out of the traversing thread guide. The front edge 30 of the lower plate 21 also touches the thread. By acting on the cylinder 32, the fingers 39, 40 move synchronously from their rest position towards the end of the sleeve 10 at which the knives 8 are arranged. As a result, the thread 43 is guided along the guide rails 28, 30. The upper finger 39 moves up to the stop 29. In this position, the thread is guided precisely in a narrow opening with little play. As a result of the offset arrangement of the fingers 39, 40, the lower finger 40 moves somewhat further, namely beyond the knives 8, 9 and beyond the end of the sleeve 10. The piece of thread guided around the sleeve 10 therefore runs obliquely to the edge of the sleeve. It lies on the sleeve in the upper area and extends beyond the sleeve edge in the lower area, penetrating the plane in which the knives 8, 9 rotate. In this case, the thread 43 is held at a safe distance from the edge of the full bobbin 42 by the stop 31 of the lower plate 21, so that it cannot slip off the edge under any circumstances.

Sobald der Faden, wie soeben beschrieben, schräg über den Rand der Hülse 10 läuft, wird er von einem der umlaufenden Messer 8, 9 erfaßt und durchgeschnitten.As soon as the thread, as just described, runs obliquely over the edge of the sleeve 10, it is gripped by one of the rotating knives 8, 9 and cut through.

Die Finger 39, 40 verbleiben zunächst noch in der vorgeschobenen Stellung. Dabei bildet der nachkommende Faden auf der Hülse 10 eine kleine Wicklung, die sich auf das abgeschnittene Fadenende legt. Nach einer vorgegebenen Zeit, d. h. nachdem die für die Anknotwicklung erforderliche Anzahl von Windungen gebildet worden ist, klappen die Bleche 20, 21 zurück. Dann fahren die Finger 39, 40 in die Ruhestellung zurück. Der Faden bewegt sich nun zunächst frei in Richtung auf die Mitte des Changierbereiches und wird dabei von dem Changierfadenführer 13 erfaßt. Dann beginnt der Aufbau einer neuen Spule.The fingers 39, 40 initially remain in the advanced position. The following thread forms a small winding on the sleeve 10, which lies on the cut end of the thread. After a predetermined time, i.e. H. after the number of turns required for the knot winding has been formed, the sheets 20, 21 fold back. Then the fingers 39, 40 move back into the rest position. The thread now moves freely towards the center of the traversing area and is gripped by the traversing thread guide 13. Then the construction of a new coil begins.
