Description

Eine Aufspulmaschine nach dem Oberbegriff ist bekannt durch die EP-A 0 114 642.A winding machine according to the preamble is known from EP-A 0 114 642.

Bei Aufspulmaschinen mit Flügelchangierung besteht das Problem, daß nicht nur die Winkelgeschwindigkeit, sondern auch die Drehlage der Flügel relativ zueinander genau aufeinander abgestimmt sein muß, um die sichere Fadenübergabe an den Hubenden zu gewährleisten. Selbst bei genauer Einjustierung der Flügelsteme relativ zu ihren Achsen beobachtet man jedoch Störungen des Spulenaufbaus insbesondere bei feinen Fäden und Chemiefasern.In winding machines with wing traversing, there is the problem that not only the angular velocity, but also the rotational position of the wings relative to one another must be precisely coordinated with one another in order to ensure the safe thread transfer at the stroke ends. Even with precise adjustment of the wing stems relative to their axes, however, disturbances in the bobbin build-up can be observed, particularly with fine threads and man-made fibers.

Aufgabe der Erfindung ist es, diese Störungen zu vermeiden. Dies geschieht dadurch, daß das Zahnspiel der Getriebeverbindung beseitigt wird, indem die Hauptwelle eines Flügelsterns sowie die Vorgelegewelle in Exzenterbuchsen gelagert und die Exzenterbuchsen relativ zum Gehäuse verstellbar sind.The object of the invention is to avoid these disorders. This is done in that the tooth play of the gear connection is eliminated by the main shaft of a wing star and the countershaft being mounted in eccentric bushings and the eccentric bushings being adjustable relative to the housing.

Diese Aufgabe wird bei einer Aufspulmaschine nach dem Oberbegriff durch die Maßnahmen des Kennzeichens des Anspruchs 1 gelöst.This object is achieved in a winding machine according to the preamble by the measures of the characterizing part of claim 1.

Durch Verdrehen der Exzenterbuchsen relativ zueinander wird bei der Montage des Getriebes zunächst die Getriebeeinheit so eingestellt, daß kein Zahnspiel mehr besteht. Sodann werden die Flügelsteme auf die entsprechenden Wellen derart montiert, daß die Flügel sich zu genau festgelegten Winkelabständen treffen.By turning the eccentric bushes relative to each other, the gear unit is set so that there is no more tooth play when assembling the gear unit. Then the wing stems are mounted on the corresponding shafts in such a way that the wings meet at precisely defined angular distances.

Die spielfreie Einstellung wird dadurch erleichtert, daß die Exzentrizität der Exzenterbuchsen ungleich ist, vorzugsweise im Verhältnis 1:2 ungleich. Dadurch kann die beim Verdrehen ihres Exzenters hervorgerufene Radialverstellung der einen Welle durch Verdrehen des Exzenters der anderen Welle eingeholt und ausgeglichen werden.The play-free adjustment is facilitated in that the eccentricity of the eccentric bushings is unequal, preferably unequal in a ratio of 1: 2. As a result, the radial adjustment of one shaft caused by rotating its eccentric can be obtained and compensated for by rotating the eccentric of the other shaft.

Die Ausrichtung der Flügelchangierung in der Aufspulmaschine wird dadurch erleichtert, daß das Getriebegehäuse in der Aufspulmaschine so befestigt wird, daß es um die Achse des Hohlrades herum verdrehbar und stufenlos feststellbar ist. Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels beschrieben.The alignment of the wing traversing in the winding machine is facilitated in that the gear housing is fastened in the winding machine in such a way that it can be rotated around the axis of the ring gear and is infinitely lockable. The invention is described below using an exemplary embodiment.

  • 1 shows the top view of the rotary planes of a traversing device;
  • Figure 2 shows the normal section - schematically - through a winding machine.
  • Fig. 3 shows the gear unit according to this invention.

Die in Fig. 2 im Querschnitt durch eine Changierung dargestellte Spulmaschine weist als wesentliche Bestandteile die Spulspindel 1 und die Changiereinrichtung 2 auf. Durch einen nicht dargestellten, mit der Spulspindel 1 verbundenen Motor wird die Spulspindel mit Drehrichtung 4 angetrieben. Auf der Spulspindel ist eine Hülse 5 fluchtend aufgespannt. Auf der Hülse 5 wird eine Kreuzspule 6 aus einem aus senkrechter Richtung anlaufenden Faden 3 gebildet. Einer Spulspindel können typischerweise drei oder vier oder sechs oder acht Fäden parallel zueinander zulaufen und zu einer entsprechenden Anzahl von Spulen 6 aufgespult werden. Jede Changiereinrichtung besteht aus mehreren umlaufenden Flügeln 7 und 8, die in zwei Drehebenen I und ll angeordnet sind. Vor diesen Flügeln liegt ein Leitlineal 9, an dem der Faden während seiner Changierung entlanggleitet. Es sei erwähnt, daß das Leitlineal auch auf der anderen Seite der Fadenlaufebene (gestrichelt eingezeichnet) liegen kann.The winding machine shown in cross-section in FIG. 2 by a traversing has as essential components the winding spindle 1 and the traversing device 2. The winding spindle is driven in the direction of rotation 4 by a motor, not shown, connected to the winding spindle 1. On the winding spindle, a sleeve 5 is clamped in alignment. On the sleeve 5, a cheese 6 is formed from a thread 3 starting from the vertical direction. A winding spindle can typically run three or four or six or eight threads parallel to one another and wound onto a corresponding number of bobbins 6. Each traversing device consists of several circumferential wings 7 and 8, which are arranged in two planes of rotation I and II. In front of these wings is a guide ruler 9, along which the thread slides as it traverses. It should be mentioned that the guideline can also lie on the other side of the thread running plane (shown in broken lines).

Die Drehebenen I, II und die Ebene 111, in der das Leitlineal 9 angeordnet ist, sind derart geneigt, daß die Drehebenen mit der durch Pfeil 10 angezeigten Fadenzulaufrichtung einen Winkel alpha zwischen 45 und 70° bilden.The rotation planes I, II and the plane 111, in which the guide rule 9 is arranged, are inclined such that the rotation planes form an angle alpha between 45 and 70 ° with the thread feed direction indicated by arrow 10.

Dadurch wird erreicht, daß sich unterhalb der Drehebene II eine Leitwalze 11 mit sehr geringem Abstand anbringen läßt. Der Faden wird in Kontakt mit dieser Leitwalze auf die jeweilige Spule 6 geführt. Dabei liegt die Leitwalze 11 in Umfangskontakt an der Spule 6. Die Leitwalze 11 kann jedoch auch einen geringen Abstand zu der Oberfläche der Spulse haben und drehend angetrieben sein.This ensures that a guide roller 11 can be attached at a very short distance below the plane of rotation II. The thread is guided onto the respective bobbin 6 in contact with this guide roller. The guide roller 11 is in circumferential contact with the coil 6. However, the guide roller 11 can also be at a short distance from the surface of the coils and be driven to rotate.

Die Flügelsteme 7 der Changiereinrichtung, die in der Drehebene I rotieren, sitzen an der Welle 15. Die Flügelsterne 8, die in der Drehebene II rotieren, sitzen an der Hohlwelle 16. Die Hohlwelle 16 ist, wie sich aus Fig. 1, 2 und 3 ergibt, exzentrisch zu der Welle 15 gelagert mit Exzentrizität E.The wing stems 7 of the traversing device, which rotate in the plane of rotation I, sit on the shaft 15. The wing stars 8, which rotate in the plane of rotation II, sit on the hollow shaft 16. The hollow shaft 16 is, as can be seen in FIGS. 1, 2 and 3 results eccentrically to the shaft 15 with eccentricity E.

Wie sich weiterhin aus Fig. 1 ergibt, weist jeder Flügelstern drei Flügel 7 bzw. 8 auf, die mit gleichem Winkelabstand von 120° zueinander versetzt sind. Zwei miteinander zusammenwirkende Flügelsteme mit ihren Flügeln 7 bzw. 8 bilden daher einen Hubbereich H längs des Leitlineals 9. Der Hubbereich erstreckt sich über einen Zentrierwinkel von im wesentlichen 60°.As can further be seen from FIG. 1, each wing star has three wings 7 and 8, which are offset from one another by the same angular distance of 120 °. Two interacting wing systems with their wings 7 and 8 therefore form a stroke area H along the guide ruler 9. The stroke area extends over a centering angle of essentially 60 °.

Für einen exakten Spulenaufbau ist es nun zum einen erforderlich, daß die relative Phasenlage der Flügelsteme so eingestellt ist, daß sich die Flügel 7, 8, die die Hin- und Herführung des Fadens durchführen, sich stets genau auf diesen 60°-Linien treffen. Bekanntlich ist die exakte Fadenübergabe an den Hubumkehrpunkten ein wesentliches Kriterium dafür, daß die entstehenden zylindrischen Spulen keine verdickten Kanten aufweisen. Andererseits hängt das exakte Funktionieren der Changiereinrichtung davon ab, daß die beiden Flügelsterne genau symmetrisch zu dem Leitlineal 9 ausgerichtet sind. Auch hierdurch wird die genaue Fadenübergabe beeinflußt.For an exact bobbin construction it is now necessary, on the one hand, that the relative phase position of the wing systems is set such that the wings 7, 8, which carry out the back and forth of the thread, always meet exactly on these 60 ° lines. As is known, the exact thread transfer at the stroke reversal points is an essential criterion for ensuring that the cylindrical bobbins that are formed do not have any thickened edges. On the other hand, the exact functioning of the traversing device depends on the two wing stars being aligned exactly symmetrically to the guide ruler 9. This also influences the exact thread transfer.

Das in Fig. 3 dargestellte Getriebe ist nun so eingerichtet, daß diese Einstellungen problemlos durchgeführt werden können. Dabei ist das Getriebe als Raueinheit ausgeführt, die einfach in das Gehäuse 74 der Spulmaschine ein- und ausgebaut werden kann.The transmission shown in Fig. 3 is now set up so that these settings can be made easily. The gear unit is designed as a roughing unit that can be easily installed and removed in the housing 74 of the winding machine.

Die Baueinheit nach Fig. 3 weist zum einen den Gehäusetopf 65 auf, der in der Aufsicht rund oder oval bzw. elliptisch ist, wobei die Hauptachse in Richtung der Exzentrizität zwischen der Hohlwelle 16 und der Welle 15 liegt. In dem Gehäusetopf 65 ist die Welle 15 der Flügel 8 drehbar gelagert. In einem ebenfalls zu der Baueinheit gehörenden Gehäusedeckel 67 ist die Hohlwelle 16 der Flügel 7 gelagert. Deckel 67 und Gehäusetopf 65 werden bei der Montage fest miteinander verschraubt. Die Hohlwelle besitzt einen Innenzahnradkranz 68, der außen eine Lauffläche 72 bzw. Verzahnung für einen Zahnradeingriff bzw. Verzahnung für einen Zahnriemeneingriff besitzt. Der Zahnradkrang 68 wird im dargestellten Fall durch Treibriemen 73 angetrieben, wozu der Gehäusetopf 65 eine entsprechende Aussparung 75 aufweist. Die Drehbewegung der Hohlwelle 16 mit dem Zahnradkranz 68 wird über Zahnrad 69, die ebenfalls in dem Gehäusetopf 65 drehbar gelagerte Vorgelegewelle 66 sowie die Zahnräder 70 und 71 auf die Welle 15 derart übertragen, daß die Welle 15 im entgegengesetzten Drehsinn, jedoch mit gleicher Drehzahl rotiert.3 has, on the one hand, the housing pot 65, which is round or oval or elliptical in plan view, the main axis in FIG Direction of eccentricity is between the hollow shaft 16 and the shaft 15. The shaft 15 of the vanes 8 is rotatably mounted in the housing pot 65. The hollow shaft 16 of the vanes 7 is mounted in a housing cover 67 which also belongs to the structural unit. Cover 67 and housing pot 65 are firmly screwed together during assembly. The hollow shaft has an internal gear rim 68, which has a tread 72 on the outside or toothing for a toothed wheel engagement or toothing for a toothed belt engagement. The gear ring 68 is driven in the case shown by drive belts 73, for which purpose the housing pot 65 has a corresponding recess 75. The rotational movement of the hollow shaft 16 with the gear rim 68 is transmitted via gear 69, the countershaft 66, which is also rotatably mounted in the housing pot 65, and the gear wheels 70 and 71 to the shaft 15 such that the shaft 15 rotates in the opposite direction of rotation, but at the same speed .

Die Welle 15 ist in einer Exzenterbuchse 76, die Vorgelegewelle 66 in einer Exzenterbuchse 77 gelagert. Bei diesen Exzenterbuchsen liegt der Außenmantel exzentrisch zur Innenbohrung. Die Exzentrizität liegt in der Größenordnung von ca. 0,5 mm, und zwar ist die Exzentrizität der Exzenterbuchse 76 der Welle 15 doppelt so groß wie die Exzentrizität der Exzenterbuchse 77, und zwar aus folgenden Gründen : Bei der Montage wird die Baueinheit zunächst ohne die Flügel montiert. Sodann wird die Exzenterbuchse 77 mit einem Spezialschlüssel durch die Aussparung 75 so weit verdreht, daß das Zahnspiel zwischen dem Innenzahnrad 68 (d. h. der Hohlwelle 16) und dem Zahnrad 69 (d. h. der Vorgelegewelle 66) beseitigt wird. Hierdurch hat sich das Zahnspiel zwischen den Zahnrädern 70 und 71 der Welle 15 vergrößert. Um dieses Zahnspiel zu eliminieren, wird nunmehr die Exzenterbuchse 76 ebenfalls durch Aussparung 75 so weit verdreht, bis auch das Zahnspiel zwischen den Zahnrädern 70, 71, d. h. zwischen der Vorgelegewelle 66 und der Welle 15 beseitigt ist. Durch Festdrehen der Schrauben 78, 79 werden die Exzenterbuchsen 76, 77 unverdrehbar im Gehäuse festgestellt. Nunmehr läuft die Getriebeeinheit spielfrei. Die Flügelsteme können in der vorgegebenen Phasenlage montiert werden. Zur Ausrichtung der Flügelsterne auf das Leitlineal 9 sind Langlöcher 80, 81 in dem Deckel 67 der Baueinheit vorgesehen. Damit wird erreicht, daß die Baueinheit so in dem Gestell 74 der Spulmaschine montiert werden kann, daß die Verbindungslinie durch die Achsen der Welle 15 einerseits und der Hohlwelle 16 andererseits genau parallel zu den Endpunkten des Leitlineals 9 liegt. Hierbei muß man sich erinnern, daß diese Verbindungslinie zunächst durch Verdrehen der Exzenterbuchsen 76 und 77 verändert wurde. Der Mittelpunkt der Langlöcher liegt dabei in der Achse der Hohlwelle 16, die ihre Lage durch das Verdrehen der Exzenterbuchsen 76, 77 nicht verändert hat.The shaft 15 is mounted in an eccentric bushing 76, the countershaft 66 in an eccentric bushing 77. The outer jacket of these eccentric bushes is eccentric to the inner bore. The eccentricity is of the order of magnitude of approx.0.5 mm, namely the eccentricity of the eccentric bushing 76 of the shaft 15 is twice as large as the eccentricity of the eccentric bushing 77, for the following reasons: during assembly, the assembly is initially without the Wing mounted. The eccentric bushing 77 is then rotated with a special key through the recess 75 so that the tooth play between the internal gear 68 (i.e. the hollow shaft 16) and the gear 69 (i.e. the countershaft 66) is eliminated. As a result, the backlash between the gears 70 and 71 of the shaft 15 has increased. To eliminate this backlash, the eccentric bushing 76 is now also rotated through the recess 75 until the backlash between the gears 70, 71, i. H. between the countershaft 66 and the shaft 15 is eliminated. By tightening the screws 78, 79, the eccentric bushes 76, 77 are fixed in the housing in a non-rotatable manner. The gear unit now runs without play. The wing stems can be installed in the specified phase. To align the wing stars with the guide ruler 9, elongated holes 80, 81 are provided in the cover 67 of the assembly. This ensures that the assembly can be mounted in the frame 74 of the winding machine so that the connecting line through the axes of the shaft 15 on the one hand and the hollow shaft 16 on the other hand is exactly parallel to the end points of the guide rule 9. It must be remembered that this connecting line was first changed by turning the eccentric bushings 76 and 77. The center point of the elongated holes lies in the axis of the hollow shaft 16, which has not changed its position due to the rotation of the eccentric bushings 76, 77.
