Definitions

  • the invention relates to a thread guide device according to the preamble of claim 1.
  • Such thread guiding devices are known, for example, from German utility model 73 23 026 (867) or German utility model 71 26 191 (815) or German patent 35 16 522 (1408). All these thread guide devices have the disadvantage that the cut - if it succeeds - must be carried out very quickly on the associated cutting device. In any case, there is a risk that the cut end of the thread will burst apart so that it cannot be found again and / or that the individual filaments get into machine parts.
  • the object of the invention is to design the known thread guide device for a running thread so that the thread can be cut by the associated cutting device at any speed and without the risk of the thread end bursting apart.
  • the cutting process should also take place essentially independently of the thread tensile forces and in particular without tensile force peaks.
  • the solution has the advantage that it creates the situation of the static thread cut at the individual thread point. That means: The thread is cut in the same way as you cut a stationary thread by hand with a knife.
  • the movement of the thread in its thread path is accompanied by a relative movement transverse to the thread path.
  • This relative movement can be generated in that the thread is also moved transversely to its path, e.g. in the traversing triangle of a thread running towards a traversing device. Therefore, the thread guide device is particularly suitable for cutting a thread running towards a full bobbin (claim 3).
  • the relative movement transverse to the thread path can also be generated in that the associated cutting device makes a movement transverse to the thread path.
  • Fig. 1 the view is shown, in Fig. 2 the section through a clamping plate 52. It serves to clamp an empty sleeve 20 and is freely rotatable and axially displaceable. The sleeve 20 is between two such clamping plates clamped.
  • the tensioning plate shown in FIG. 1/2 serves at the same time to catch the thread 8.
  • the thread 8 is delivered by a delivery unit (not shown here) and drawn off by a suction gun 53.
  • the clamping plate has an outer edge 54 and an inner edge 55, between which a circumferential groove with a groove base 58 is formed.
  • the inner edge on which one looks in FIG. 1, has a slot 57, which starts from the outer circumference and points secantially against the direction of rotation 56.
  • a cutting device with a knife 34 is attached between the inner and outer edges 54 and 55, respectively.
  • the cutting device is cut in FIGS. 2A, 2B.
  • it has a wedge-shaped knife 34.
  • the knife is attached to one outer edge, for example 54, in such a way that it points into the groove 58 between the inner and the outer edge 54 and 55 and leaves a wedge-shaped gap open to the outer circumference of the clamping plate 52. That end of the knife which faces the groove base 58 formed between the two edges 54, 55 protrudes axially between two guide edges which are parallel to the knife blade and on both sides of the knife blade.
  • the guide edges are formed by two webs 60, 61 which are attached to the opposite edge 55 and fill the groove in a wedge shape from the inside to the outside, the slope being opposite to that of the knife.
  • the webs and knives thus form an open wedge gap.
  • a recess 59 of the inner edge 55 is provided instead.
  • the side edges of this recess run parallel to the knife plane, but in such a way that they maintain a small distance from the knife plane. In this way, the recess 59 forms the guide edges 51 on both sides of the knife 34.
  • the knife 34 and side edges 51 form a wedge gap, which is open to the outer circumference of the clamping plate 52 and narrows towards the bottom 58 of the groove formed between the edges 54 and 55.
  • a thread 8 which is drawn into this wedge gap, is therefore tensioned between the guide edges 51 and the knife edge 36, as shown in FIGS. 4 and 5.
  • the knife 34 and the guide edges 51 are now also aligned such that the knife plane and the guide edges run essentially on an involute to the groove base 58 of the groove formed between the edges 54 and 55. This would be an ideal shape. As can be seen from the drawing, it is sufficient that the course of an involute is approximated. It is not detrimental to the function that the knife is straight and therefore represents the tendon or tangent of an involute.
  • the thread 8 sucked off by the suction gun 53 is placed with a partial wrap on the empty sleeve 20 clamped between the clamping plates 52 and thereby placed over the inner edge 55 of the one clamping plate 52.
  • the thread is gripped by the projecting nose 57a of the slot 57 and drawn out into a loop with two pieces of thread.
  • the thread center facing the suction pistol falls into the groove between the outer edge 54 and the inner edge 55 and partially wraps around the groove base 58.
  • the cutting device 34 is offset against the direction of rotation 56 with respect to the slot 57, namely — as shown in FIG. 1 — by approximately 180 °, the thread center gets into the cutting device 34 after a partial wrap.
  • the thread has a movement component perpendicular to the knife edge. Therefore, it is also avoided that the thread is roughened very much and may adopt a structure similar to the so-called edge crimp.
  • This cutting device creates a very defined, smooth thread end, the retrieval of which makes no difficulties.
  • FIG 3 shows the perspective view of a winding unit 2.
  • the traversing drive and the drive roller required for the winding drive are not shown in this illustration.
  • the thread 8 is wound on the winding tube 20.
  • the winding tube 20 is clamped between two clamping plates 52, which are freely rotatable.
  • the situation is shown here in which the thread of the winding tube 20 rotated in the crawl gear runs in before it is inserted again into the traversing device 10.
  • the thread 8 is guided through the guide fork 16 on the guide arm 15 outside the traversing area to the empty tube 20.
  • the traversing area is predetermined by the slot length 30 of the thread guide or traversing device 10.
  • a suction opening required for sucking off the cut thread is formed by a radial jacket opening 27 in the intake manifold, a deflection rail 17 in the tube longitudinal region of the jacket opening having a recess 28 lying radially above the jacket opening 27, which opening is slot-shaped (29) in the direction of the winding tube 20.
  • the recess surrounds the jacket opening 27 at a distance.
  • This slot-shaped opening serves the purpose of catching the thread approached from the left in the recess 28, so that it always runs in the catching area of the suction opening 27, regardless of any further traversing movement.
  • the catch area of the suction opening must therefore be at least as large as the area of the recess 28 in the deflection rail. The process of ending the winding trip is described below.
  • the suction tube 14 is rotated in the pivoting direction 31 in order to initiate the traversing.
  • the knife 34 fastened to the knife holder 33 is fixedly connected to the suction pipe.
  • the knife has a slit 35 lying in the traversing plane, into which the thread which has been traversed from the left runs.
  • the slit 35 is overlapped in a wedge-shaped manner by the knife edge 36 and thus narrows for the thread that is chucked into it.
  • the thread is pressed against the knife edge, which increases the thread tension. This ensures a safe cutting of the thread.
  • the knife 34 is equipped with a slot 35.
  • Such an arrangement assumes that the thread is always chucked into the slot from one direction. For this reason, the knife has at its end facing away from the slot 35 an overflow edge 37 which pierces the traversing plane at an angle and points essentially in the traversing direction. The overflow edge is easily overrun by the thread, provided that it is being changed from right to left. During the next traverse stroke from left to right, the thread is then shifted into the slot and cut.
  • the slot approaches from the opening to the end of the empty sleeve 20 (deflection of the end towards the coil).
  • the knife 34 can be rotated about an axis of rotation 38 which is attached to the knife holder 33 in such a way that its rear end can be raised or lowered with respect to the traversing plane.
  • the angle between the traversing plane and the slot determines the inclination of the knife.
  • a fastening screw 39 which is guided in a slot which is circular with respect to the axis of rotation 38, is used for precise adjustment of the inclination or inclination.
  • Figures 4 and 5 show details of the execution of the knife.
  • the knife blade is inclined such that the angle between the blade plane and the traversing plane is not 90 °. This angle is labeled "alpha".
  • the blade plane is inclined so that the Knife cutting edge 36 points towards the incoming thread.
  • the angle alpha which is less than 90 °, is behind the blade plane when viewed in the thread running direction.
  • Fig. 5 shows a possible view from above.
  • the knife plate 34.1 is arranged obliquely to the center line 47 of the traversing triangle.
  • the knife plate 34.1 is fastened to the suction pipe with the knife holder 33, which is not shown here.
  • the knife plate 34.1 With respect to the center line 47 of the traversing triangle, the knife plate 34.1 is rotated in such a way that the knife edge 36 approaches the winding tube from the beginning to its end.
  • the angle beta which the knife edge 36 forms with the center line 47 of the traversing triangle, is less than 90 ° behind the knife edge 36 in the running direction of the thread.
  • the thread is traversed in the traversing direction 48 across the knife edge.
  • 4 shows the side view of the traversing plane 50 and the traversing directions 48 are each perpendicular to the sheet plane.
  • the running direction of the thread is shown at 49.
  • the knife blade 34 is fastened to the knife plate 34.1.
  • the knife plate 34.1 and the knife blade 34 do not lie flat against one another, but form a distance between them which prevents the thread from jamming. This also avoids the accumulation of thread residues and fluff.
  • the knife edge penetrates the traversing plane obliquely, so that the thread is further away from the traversing plane while the knife edge is overflowing. It is pulled by the knife edge 36 under the guide edges 51 and additionally tightened. As a result, the wrap angle of the thread on the knife edge 36 increases further, as a result of which the frictional forces between the thread and the looped knife edge continue to increase. This continues until the thread is cut. As a result of the increasing frictional force which the looped knife edge 36 exerts on the thread, the thread pulling force of the thread which is still wound increases, which also favors the separation process.
  • the principle of cutting which is realized by the knife, is that the knife edge 36 is aligned so that the thread or a single thread point that comes into contact with the knife edge 36 does not perform any relative movement transversely to the knife edge 36.
  • the principle also states that when the thread slides on the knife edge it is guided into a wedge gap which the knife edge 36 forms with guide edges 51 lying in front of and / or behind the knife plane.
  • the thread between the guide edges 51 on the one hand and the knife edge 36 on the other hand is increasingly tensioned, so that the thread on the knife edge 36 forms an angle, preferably an increasingly acute angle.
  • the design and alignment of the knife ensure that the thread has essentially no component of motion transverse to the knife edge.
  • the knife is thus equipped and set up so that the cutting process fully corresponds to the way in which you naturally cut a thread with a knife.

Description

Die Erfindung betrifft eine Fadenführungseinrichtung nach dem Oberbegriff des Anspruchs 1.
Solche Fadenführungseinrichtungen sind z.B. bekannt durch das deutsche Gebrauchsmuster 73 23 026 (867) oder das deutsche Gebrauchsmuster 71 26 191 (815) oder das deutsche Patent 35 16 522 (1408). Bei allen diesen Fadenführungseinrichtungen besteht der Nachteil, daß an der zugehörigen Schneidvorrichtung der Schnitt - soll er gelingen - sehr schnell durchgeführt werden muß. In jedem Fall besteht die Gefahr, daß das geschnittene Fadenende auseinanderplatzt, so daß es nicht wiedergefunden werden kann und/oder so daß die einzelnen Filamente in Maschinenteile geraten.The invention relates to a thread guide device according to the preamble of claim 1.
Such thread guiding devices are known, for example, from German utility model 73 23 026 (867) or German utility model 71 26 191 (815) or German patent 35 16 522 (1408). All these thread guide devices have the disadvantage that the cut - if it succeeds - must be carried out very quickly on the associated cutting device. In any case, there is a risk that the cut end of the thread will burst apart so that it cannot be found again and / or that the individual filaments get into machine parts.

Ähnliche Schwierigkeiten sind bei Schneidvorrichtungen zu erwarten, wie sie aus der US-A-4106711 und der AT-A-332263 bekannt sind.Similar difficulties can be expected with cutting devices as are known from US-A-4106711 and AT-A-332263.

Aufgabe der Erfindung ist es, die bekannte Fadenführungseinrichtung für einen laufenden Faden so auszugestalten, daß der Faden von der zugehörigen Schneidvorrichtung mit beliebiger Geschwindigkeit und ohne die Gefahr des Auseinanderplatzens des Fadenendes geschnitten werden kann. Auch soll der Schneidvorgang im wesentlichen unabhängig von den Fadenzugkräften und insbesondere ohne Zugkraftspitzen vonstatten gehen.The object of the invention is to design the known thread guide device for a running thread so that the thread can be cut by the associated cutting device at any speed and without the risk of the thread end bursting apart. The cutting process should also take place essentially independently of the thread tensile forces and in particular without tensile force peaks.

Die Lösung ergibt sich aus dem Kennzeichen des Anspruchs 1.The solution results from the characterizing part of claim 1.

Die Lösung hat den Vorteil, daß durch sie an dem einzelnen Fadenpunkt die Situation des statischen Fadenschnitts entsteht. Das heißt: Der Faden wird so geschnitten, wie man einen stillstehenden Faden von Hand mit einem Messer zerschneidet.The solution has the advantage that it creates the situation of the static thread cut at the individual thread point. That means: The thread is cut in the same way as you cut a stationary thread by hand with a knife.

Wesentlich dabei ist, daß zu der Bewegung des Fadens in seinem Fadenweg eine Relativbewegung quer zum Fadenweg hinzukommt. Diese Relativbewegung kann einmal dadurch erzeugt werden, daß der Faden zusätzlich auch quer zu seinem Weg bewegt wird, wie es z.B. in dem Changierdreieck eines einer Changiereinrichtung zulaufenden Fadens der Fall ist. Daher eignet sich die Fadenführungseinrichtung insbesondere zum Kappen eines einer vollen Spule zulaufenden Fadens (Anspruch 3). Die Relativbewegung quer zum Fadenweg kann aber auch dadurch erzeugt werden, daß die zugehörige Schneidvorrichtung eine Bewegung quer zum Fadenweg macht.It is essential that the movement of the thread in its thread path is accompanied by a relative movement transverse to the thread path. This relative movement can be generated in that the thread is also moved transversely to its path, e.g. in the traversing triangle of a thread running towards a traversing device. Therefore, the thread guide device is particularly suitable for cutting a thread running towards a full bobbin (claim 3). The relative movement transverse to the thread path can also be generated in that the associated cutting device makes a movement transverse to the thread path.

Diese Situation ist z.B. gegeben beim Fangen eines Fadens in einem Spulteller, wie er z.B. in dem deutschen Patent 35 16 522 beschrieben ist. Hier kann die Schneidvorrichtung an der erfindungsgemäßen Fadenführungseinrichtung die dort angegebene Schneidvorrichtung vorteilhaft ersetzen (Anspruch 4).This situation is e.g. given when catching a thread in a reel plate, as e.g. is described in German Patent 35 16 522. Here, the cutting device on the thread guide device according to the invention can advantageously replace the cutting device specified there (claim 4).

Im folgenden wird die Erfindung anhand von zwei Ausführungsbeispielen einer Fadenführungseinrichtung mit jeweils einer Schneidvorrichtung zum Kappen des Fadens, der einer vollen Spule zuläuft, und einer Schneidvorrichtung an einem Spulteller beschrieben.In the following, the invention is described on the basis of two exemplary embodiments of a thread guiding device, each with a cutting device for cutting the thread, which runs into a full bobbin, and a cutting device on a bobbin plate.

In Fig. 1 ist die Ansicht, in Fig. 2 der Schnitt durch einen Spannteller 52 dargestellt. Er dient zum Einspannen einer Leerhülse 20 und ist frei drehbar und axial verschiebbar gelagert. Die Hülse 20 wird zwischen zwei derartigen Spanntellern eingespannt. Der in Fig. 1/2 dargestellte Spannteller dient gleichzeitig zum Fangen des Fadens 8. Der Faden 8 wird durch ein hier nicht dargestelltes Lieferwerk angeliefert und durch eine Saugpistole 53 abgezogen. Der Spannteller weist einen äußeren Rand 54 und einen inneren Rand 55 auf, zwischen denen eine Umfangsnut mit Nutengrund 58 gebildet wird. Der innere Rand, auf welchen man in Fig. 1 blickt, weist einen vom Außenumfang ausgehenden, gegen die Drehrichtung 56 sekantial weisenden Schlitz 57 auf. Gegen die Drehrichtung hierzu versetzt, ist eine Schneideinrichtung mit einem Messer 34 zwischen dem inneren und dem äußeren Rand 54 bzw. 55 angebracht. Die Schneideinrichtung ist in Fig. 2A, 2B geschnitten. Sie weist in beiden dargestellten Ausführungen ein keilförmiges Messer 34 auf. Das Messer ist an dem einen äußeren Rand, z.B. 54 so angebracht, daß es in die Nut 58 zwischen dem inneren und dem äußeren Rand 54 bzw. 55 weist und zum Außenumfang des Spanntellers 52 einen keilförmigen Spalt offen läßt. Dasjenige Ende des Messers, welches dem zwischen den beiden Rändern 54, 55 gebildeten Nutengrund 58 zugewandt ist, ragt axial zwischen zwei Führungskanten, die zu dem Messerblatt parallel und beidseits des Messerblattes liegen. Die Führungskanten werden in der Ausführung nach Fig. 2B durch zwei Stege 60, 61 gebildet, die an dem gegenüberliegenden Rand 55 angebracht sind und die Nut von innen nach außen keilförmig ausfüllen, wobei die Steigung der des Messers entgegengesetzt ist. Stege und Messer bilden also einen nach außen offenen Keilspalt. In der Ausführung nach Fig. 2A ist stattdessen eine Ausnehmung 59 des inneren Randes 55 vorgesehen. Die Seitenkanten dieser Ausnehmung verlaufen parallel zu der Messerebene, jedoch so, daß sie einen geringen Abstand zu der Messerebene einhalten. Auf diese Weise bildet die Ausnehmung 59 die Führungskanten 51 beidseits des Messers 34. Auch hier bilden Messer 34 und Seitenkanten 51 einen Keilspalt, welcher zum Außenumfang des Spanntellers 52 hin offen ist und sich zum Nutengrund 58 der zwischen den Rändern 54 und 55 gebildeten Nut hin verengt. Ein Faden 8, welcher in diesen Keilspalt hineingezogen wird, wird daher zwischen den Führungskanten 51 und der Messerschneide 36 verspannt, wie es in den Figuren 4 und 5 dargestellt ist. Insofern wird auf die nachfolgende Beschreibung zu den Figuren 4 und 5 verwiesen. Das Messer 34 sowie die Führungskanten 51 sind nun außerdem so ausgerichtet, daß die Messerebene und die Führungskanten im wesentlichen auf einer Evolvente zum Nutengrund 58 der zwischen den Rändern 54 und 55 gebildeten Nut verlaufen. Dies wäre eine Idealform. Wie aus der Zeichnung ersichtlich, genügt es, daß der Verlauf einer Evolventen angenähert ist. Es ist für die Funktion unschädlich, daß das Messer gerade ist und insofern die Sehne oder Tangente einer Evolventen darstellt.In Fig. 1 the view is shown, in Fig. 2 the section through a clamping plate 52. It serves to clamp an empty sleeve 20 and is freely rotatable and axially displaceable. The sleeve 20 is between two such clamping plates clamped. The tensioning plate shown in FIG. 1/2 serves at the same time to catch the thread 8. The thread 8 is delivered by a delivery unit (not shown here) and drawn off by a suction gun 53. The clamping plate has an outer edge 54 and an inner edge 55, between which a circumferential groove with a groove base 58 is formed. The inner edge, on which one looks in FIG. 1, has a slot 57, which starts from the outer circumference and points secantially against the direction of rotation 56. Offset from the direction of rotation, a cutting device with a knife 34 is attached between the inner and outer edges 54 and 55, respectively. The cutting device is cut in FIGS. 2A, 2B. In both of the versions shown, it has a wedge-shaped knife 34. The knife is attached to one outer edge, for example 54, in such a way that it points into the groove 58 between the inner and the outer edge 54 and 55 and leaves a wedge-shaped gap open to the outer circumference of the clamping plate 52. That end of the knife which faces the groove base 58 formed between the two edges 54, 55 protrudes axially between two guide edges which are parallel to the knife blade and on both sides of the knife blade. In the embodiment according to FIG. 2B, the guide edges are formed by two webs 60, 61 which are attached to the opposite edge 55 and fill the groove in a wedge shape from the inside to the outside, the slope being opposite to that of the knife. The webs and knives thus form an open wedge gap. In the embodiment according to FIG. 2A, a recess 59 of the inner edge 55 is provided instead. The side edges of this recess run parallel to the knife plane, but in such a way that they maintain a small distance from the knife plane. In this way, the recess 59 forms the guide edges 51 on both sides of the knife 34. Here too, the knife 34 and side edges 51 form a wedge gap, which is open to the outer circumference of the clamping plate 52 and narrows towards the bottom 58 of the groove formed between the edges 54 and 55. A thread 8, which is drawn into this wedge gap, is therefore tensioned between the guide edges 51 and the knife edge 36, as shown in FIGS. 4 and 5. In this respect, reference is made to the following description of FIGS. 4 and 5. The knife 34 and the guide edges 51 are now also aligned such that the knife plane and the guide edges run essentially on an involute to the groove base 58 of the groove formed between the edges 54 and 55. This would be an ideal shape. As can be seen from the drawing, it is sufficient that the course of an involute is approximated. It is not detrimental to the function that the knife is straight and therefore represents the tendon or tangent of an involute.

Zur Funktion:
Der von der Saugpistole 53 abgesaugte Faden 8 wird mit einer teilweisen Umschlingung auf die zwischen den Spanntellern 52 eingespannte Leerhülse 20 gelegt und dabei über den inneren Rand 55 des einen Spanntellers 52 gelegt. Dadurch wird der Faden von der vorspringenden Nase 57a des Schlitzes 57 erfaßt und zu einer Schlaufe mit zwei Fadenstücken ausgezogen. Das zur Saugpistole weisende Fadentrum fällt dabei in die Nut zwischen dem äußeren Rand 54 und dem inneren Rand 55 und umschlingt den Nutengrund 58 teilweise. Da nun die Schneideinrichtung 34 gegen die Drehrichtung 56 gegenüber dem Schlitz 57 versetzt ist, und zwar - wie in Fig. 1 dargestellt - etwa um 180°, gerät das Fadentrum nach einer Teilumschlingung in die Schneideinrichtung 34. Es sei bemerkt, daß infolge der Umschlingungsreibung das Fadentrum wieder aus der Saugpistole 53 herausgezogen wird und daher eine Bewegungsrichtung in der Bewegungsrichtung des Nutengrundes 58 gleich Bewegungsrichtung 56 hat. Da ferner das Messer längs einer Evolventen ausgerichtet ist, ist die Relativbewegung zwischen der Schneideinrichtung 34 und dem Faden auf eine Querbewegung beschränkt. Der Faden führt also keine Bewegung senkrecht zum Messer 36 aus. Bei weiterer Drehung des Spanntellers 52 gerät der Faden mehr und mehr in den Keilspalt, welcher zwischen dem Messer 36 und den Führungskanten 51 gebildet wird. Dabei wird er zunehmend verspannt und schließlich glatt, das heißt: in einer einzigen Radialebene des Fadens zerschnitten.About the function:
The thread 8 sucked off by the suction gun 53 is placed with a partial wrap on the empty sleeve 20 clamped between the clamping plates 52 and thereby placed over the inner edge 55 of the one clamping plate 52. As a result, the thread is gripped by the projecting nose 57a of the slot 57 and drawn out into a loop with two pieces of thread. The thread center facing the suction pistol falls into the groove between the outer edge 54 and the inner edge 55 and partially wraps around the groove base 58. Now that the cutting device 34 is offset against the direction of rotation 56 with respect to the slot 57, namely — as shown in FIG. 1 — by approximately 180 °, the thread center gets into the cutting device 34 after a partial wrap. It should be noted that as a result of the wrap friction the thread center is pulled out of the suction gun 53 again and therefore a direction of movement in the direction of movement of the groove base 58 has the same direction of movement 56. Furthermore, since the knife is aligned along an involute, the relative movement between the cutting device 34 and the thread is limited to a transverse movement. The thread therefore does not move perpendicularly to the knife 36. With further rotation of the tensioning plate 52, the thread gets more and more into the wedge gap which is formed between the knife 36 and the guide edges 51. It becomes increasingly tense and finally smooth, i.e. cut in a single radial plane of the thread.

Bei der Ausbildung und Ausrichtung des Messers nach dieser Erfindung wird vermieden, daß der Faden eine Bewegungskomponente senkrecht zur Messerschneide hat. Daher wird auch vermieden, daß der Faden sehr stark aufgerauht wird und unter Umständen eine der sog. Kantenkräuselung ähnliche Struktur annimmt. Es entsteht also mit dieser Schneideinrichtung ein sehr definiertes glattes Fadenende, dessen Wiederauffinden keine Schwierigkeiten macht.In the formation and alignment of the knife according to this invention, it is avoided that the thread has a movement component perpendicular to the knife edge. Therefore, it is also avoided that the thread is roughened very much and may adopt a structure similar to the so-called edge crimp. This cutting device creates a very defined, smooth thread end, the retrieval of which makes no difficulties.

Der Faden 8 wird auf der Spulhülse 20 aufgewickelt. Die Spulhülse 20 ist zwischen zwei Spanntellern 52, die frei drehbar gelagert sind, eingespannt. Gezeigt ist hier die Situation, in der der Faden der im Kriechgang gedrehten Spulhülse 20 zuläuft, bevor er wieder in die Changiereinrichtung 10 eingelegt wird. Hierzu wird der Faden 8 durch die Führungsgabel 16 am Führungsarm 15 außerhalb des Changierbereichs zur Leerhülse 20 geführt. Der Changierbereich ist durch die Schlitzlänge 30 des Fadenführers bzw. der Changiereinrichtung 10 vorgegeben. Eine zum Absaugen des geschnittenen Fadens erforderliche Saugöffnung wird durch eine radiale Mantelöffnung 27 im Saugrohr gebildet, wobei eine Umlenkschiene 17 im Rohrlängsbereich der Mantelöffnung eine radial über der Mantelöffnung 27 liegende Aussparung 28 aufweist, welche in Richtung zur Spulhülse 20 schlitzförmig (29) geöffnet ist. Die Aussparung umgibt die Mantelöffnung 27 mit Abstand. Diese schlitzförmige Öffnung dient dem Zweck, den von links heranchangierten Faden in der Aussparung 28 einzufangen, so daß er unabhängig von weiterer Changierbewegung stets im Fangbereich der Saugöffnung 27 läuft. Der Fangbereich der Saugöffnung hat daher mindestens so groß zu sein wie der Bereich der Aussparung 28 in der Umlenkschiene.
Im folgenden wird der Vorgang der Beendigung der Spulreise beschrieben.3 shows the perspective view of a winding unit 2. The traversing drive and the drive roller required for the winding drive are not shown in this illustration. The thread 8 is wound on the winding tube 20. The winding tube 20 is clamped between two clamping plates 52, which are freely rotatable. The situation is shown here in which the thread of the winding tube 20 rotated in the crawl gear runs in before it is inserted again into the traversing device 10. For this purpose, the thread 8 is guided through the guide fork 16 on the guide arm 15 outside the traversing area to the empty tube 20. The traversing area is predetermined by the slot length 30 of the thread guide or traversing device 10. A suction opening required for sucking off the cut thread is formed by a radial jacket opening 27 in the intake manifold, a deflection rail 17 in the tube longitudinal region of the jacket opening having a recess 28 lying radially above the jacket opening 27, which opening is slot-shaped (29) in the direction of the winding tube 20. The recess surrounds the jacket opening 27 at a distance. This slot-shaped opening serves the purpose of catching the thread approached from the left in the recess 28, so that it always runs in the catching area of the suction opening 27, regardless of any further traversing movement. The catch area of the suction opening must therefore be at least as large as the area of the recess 28 in the deflection rail.
The process of ending the winding trip is described below.

Am Ende der Spulreise wird das Saugrohr 14 in der Schwenkrichtung 31 gedreht, um das Changierende einzuleiten. Fest mit dem Saugrohr verbunden ist hierzu das an dem Messerhalter 33 befestigte Messer 34. Bezüglich der Einzelheiten für die Ausbildung eines derartigen Messerhalters wird auf die Figuren 4 und 5 verwiesen. Das Messer weist einen in der Changierebene liegenden Schlitz 35 auf, in welchen der von links changierte Faden hineinläuft. Der Schlitz 35 wird von der Messerschneide 36 keilförmig überlappt und verengt sich somit für den hineinchangierten Faden. Infolge der Verengung wird der Faden an die Messerschneide gedrückt, wodurch die Fadenspannung ansteigt. Hierdurch erfolgt ein sicheres Schneiden des Fadens. Da der von links kommende Faden auch von dem Schlitz 29 der Aussparung 28 gefangen wird, befindet er sich mit seinem abgeschnittenen Ende zwangsläufig im Fangbereich der Saugöffnung und wird folglich nach dem Abschneiden durch das Absaugrohr 14 abgesaugt. Eine Besonderheit bei der gezeigten Ausführung besteht darin, daß das Messer 34 mit einem Schlitz 35 ausgestattet ist. Eine derartige Anordnung setzt voraus, daß der Faden stets von einer Richtung in den Schlitz hineinchangiert wird. Aus diesem Grunde trägt das Messer an seinem dem Schlitz 35 abgewandten Ende eine Überlaufkante 37, welche die Changierebene schräg durchstößt und im wesentlichen in Changierrichtung zeigt. Die Überlaufkante wird von dem Faden problemlos überlaufen, sofern er gerade von rechts nach links changiert wird. Während des nächsten Changierhubs von links nach rechts wird der Faden alsdann in den Schlitz hineinchangiert und abgeschnitten. Eine weitere Besonderheit besteht darin, daß sich der Schlitz von der Öffnung bis zum Ende der Leerhülse 20 nähert (Auslenkung des Endes in Richtung zur Spule). Als weitere Besonderheit ist das Messer 34 um eine Drehachse 38, die an dem Messerhalter 33 angebracht ist, derart drehbar, daß es mit seinem hinteren Ende bezüglich der Changierebene angehoben bzw. abgesenkt werden kann. Der Winkel zwischen der Changierebene und dem Schlitz bestimmt die Neigung des Messers. Zur genauen Einstellung der Neigung bzw. Schrägstellung dient eine Befestigungsschraube 39, die in einem bezüglich der Drehachse 38 kreisförmigen Schlitz geführt ist. Infolge der Auslenkung des Endes des Schlitzes in Richtung zur Spule wird eine selbstverstärkende Klemmwirkung des sich verengenden Schlitzes und damit ein sicheres Abschneiden des Fadens hervorgerufen, da der hineinchangierte Faden eine Straffung erfährt. Die Neigung bzw. Schrägstellung bewirkt eine zusätzliche Fadenstraffung während des Überlaufs über die Messerschneide, da der Faden zwangsweise bis zum Schnitt unter seiner Fadenzugkraft über die Changierebene angehoben wird.At the end of the winding cycle, the suction tube 14 is rotated in the pivoting direction 31 in order to initiate the traversing. For this purpose, the knife 34 fastened to the knife holder 33 is fixedly connected to the suction pipe. With regard to the details for the formation of such a knife holder, reference is made to FIGS. 4 and 5. The knife has a slit 35 lying in the traversing plane, into which the thread which has been traversed from the left runs. The slit 35 is overlapped in a wedge-shaped manner by the knife edge 36 and thus narrows for the thread that is chucked into it. As a result of the narrowing, the thread is pressed against the knife edge, which increases the thread tension. This ensures a safe cutting of the thread. Since the thread coming from the left is also caught by the slot 29 of the recess 28, its cut end is inevitably in the catch area of the suction opening and is consequently sucked off by the suction pipe 14 after being cut off. A special feature of the embodiment shown is that the knife 34 is equipped with a slot 35. Such an arrangement assumes that the thread is always chucked into the slot from one direction. For this reason, the knife has at its end facing away from the slot 35 an overflow edge 37 which pierces the traversing plane at an angle and points essentially in the traversing direction. The overflow edge is easily overrun by the thread, provided that it is being changed from right to left. During the next traverse stroke from left to right, the thread is then shifted into the slot and cut. Another peculiarity is that the slot approaches from the opening to the end of the empty sleeve 20 (deflection of the end towards the coil). As a further special feature, the knife 34 can be rotated about an axis of rotation 38 which is attached to the knife holder 33 in such a way that its rear end can be raised or lowered with respect to the traversing plane. The angle between the traversing plane and the slot determines the inclination of the knife. A fastening screw 39, which is guided in a slot which is circular with respect to the axis of rotation 38, is used for precise adjustment of the inclination or inclination. As a result of the deflection of the end of the slot in the direction of the bobbin, a self-reinforcing clamping action of the narrowing slot and thus a safe cutting of the thread is brought about, since the thread that is caught is tightened. The inclination or inclination causes an additional thread tensioning during the overflow over the knife edge, since the thread is forcibly lifted up to the cut under the thread pulling force over the traversing plane.

Die Figuren 4 und 5 zeigen Details zur Ausführung des Messers. In Fig. 4 ist die Messerklinge derart geneigt, daß der Winkel zwischen der Klingenebene und der Changierebene nicht 90° ist. Dieser Winkel ist mit "alpha" bezeichnet. Die Klingenebene ist so geneigt, daß die Messerschneide 36 dem ankommenden Faden entgegenzeigt. Demzufolge liegt der Winkel alpha, der weniger als 90° beträgt, in Fadenlaufrichtung gesehen, hinter der Klingenebene.Figures 4 and 5 show details of the execution of the knife. In Fig. 4 the knife blade is inclined such that the angle between the blade plane and the traversing plane is not 90 °. This angle is labeled "alpha". The blade plane is inclined so that the Knife cutting edge 36 points towards the incoming thread. As a result, the angle alpha, which is less than 90 °, is behind the blade plane when viewed in the thread running direction.

Fig. 5 zeigt eine mögliche Ansicht von oben. Hierbei ist die Messerplatte 34.1 schräg zur Mittellinie 47 des Changierdreiecks angeordnet. Die Messerplatte 34.1 ist mit dem Messerhalter 33, der hier nicht gezeigt ist, an dem Saugrohr befestigt. Bezüglich der Mittellinie 47 des Changierdreiecks ist die Messerplatte 34.1 derart gedreht, daß sich die Messerschneide 36 von Beginn an bis zu ihrem Ende der Spulhülse nähert. Demzufolge ist der Winkel beta, welchen die Messerschneide 36 mit der Mittellinie 47 des Changierdreiecks bildet, in Laufrichtung des Fadens gesehen hinter der Messerschneide 36 kleiner als 90°. In dem gezeigten Fall wird der Faden in der Changierrichtung 48 quer über die Messerschneide changiert.
Abweichend hiervon zeigt Fig. 4 die Seitenansicht der Changierebene 50 und die Changierrichtungen 48 stehen jeweils senkrecht zur Blattebene. Die Laufrichtung des Fadens ist mit 49 gezeigt.Fig. 5 shows a possible view from above. Here, the knife plate 34.1 is arranged obliquely to the center line 47 of the traversing triangle. The knife plate 34.1 is fastened to the suction pipe with the knife holder 33, which is not shown here. With respect to the center line 47 of the traversing triangle, the knife plate 34.1 is rotated in such a way that the knife edge 36 approaches the winding tube from the beginning to its end. As a result, the angle beta, which the knife edge 36 forms with the center line 47 of the traversing triangle, is less than 90 ° behind the knife edge 36 in the running direction of the thread. In the case shown, the thread is traversed in the traversing direction 48 across the knife edge.
4 shows the side view of the traversing plane 50 and the traversing directions 48 are each perpendicular to the sheet plane. The running direction of the thread is shown at 49.

Für die Figuren 4 und 5 gilt gemeinsam: Die Messerklinge 34 ist an der Messerplatte 34.1 befestigt. Die Messerplatte 34.1 und die Messerklinge 34 liegen nicht flächig aneinander, sondern bilden zwischen sich einen Abstand, durch den ein Verklemmen des Fadens verhindert wird. Weiterhin wird hierdurch das Ansammeln von Fadenresten und Flusen vermieden.The following applies to FIGS. 4 and 5: the knife blade 34 is fastened to the knife plate 34.1. The knife plate 34.1 and the knife blade 34 do not lie flat against one another, but form a distance between them which prevents the thread from jamming. This also avoids the accumulation of thread residues and fluff.

Zur Funktion:
Der Faden zieht sich infolge der Changierbewegung unter Selbsthemmung so in die Verengung, daß eine einzige Fadenstelle auf der Messerschneide 36 entlanggleitet.About the function:
As a result of the traversing movement under self-locking, the thread pulls into the constriction in such a way that a single thread point slides along on the knife edge 36.

Die Messerschneide durchstößt die Changierebene schräg, so daß der Faden während des Überlaufen der Messerschneide weiter von der Changierebene entfernt wird. Er wird von der Messerschneide 36 unter die Führungskanten 51 gezogen und zusätzlich gestrafft. Hierdurch wird erreicht, daß der Umschlingungswinkel des Fadens an der Messerschneide 36 weiter zunimmt, wodurch die Reibkräfte zwischen dem Faden und der umschlungenen Messerschneide weiter ansteigen. Dies erfolgt, solange bis der Faden durchgetrennt ist. Infolge der zunehmenden Reibkraft, welche die umschlungene Messerschneide 36 auf den Faden ausübt, nimmt die Fadenzugkraft des weiterhin aufgewickelten Fadens zu, was den Trennvorgang ebenfalls begünstigt.The knife edge penetrates the traversing plane obliquely, so that the thread is further away from the traversing plane while the knife edge is overflowing. It is pulled by the knife edge 36 under the guide edges 51 and additionally tightened. As a result, the wrap angle of the thread on the knife edge 36 increases further, as a result of which the frictional forces between the thread and the looped knife edge continue to increase. This continues until the thread is cut. As a result of the increasing frictional force which the looped knife edge 36 exerts on the thread, the thread pulling force of the thread which is still wound increases, which also favors the separation process.

Das Schneidprinzip, das durch das Messer verwirklicht ist, besteht darin, daß die Messerschneide 36 so ausgerichtet wird, daß der Faden bzw. ein einzelner Fadenpunkt, der mit der Messerschneide 36 in Berührung kommt, keine Relativbewegung quer zur Messerschneide 36 ausführt. Das Prinzip besagt ferner, daß der Faden beim Abgleiten auf der Messerkante in einen Keilspalt geführt wird, welchen die Messerschneide 36 mit vor und/oder hinter der Messerebene liegenden Führungskanten 51 bildet. Dadurch wird der Faden zwischen den Führungskanten 51 einerseits und der Messerschneide 36 andererseits zunehmend verspannt, so daß der Faden auf der Messerschneide 36 einen Winkel, vorzugsweise einen zunehmend spitzer werdenden Winkel bildet. Dabei sorgen Ausbildung und Ausrichtung des Messers dafür, daß der Faden im wesentlichen keine Bewegungskomponente quer zur Messerschneide hat.The principle of cutting, which is realized by the knife, is that the knife edge 36 is aligned so that the thread or a single thread point that comes into contact with the knife edge 36 does not perform any relative movement transversely to the knife edge 36. The principle also states that when the thread slides on the knife edge it is guided into a wedge gap which the knife edge 36 forms with guide edges 51 lying in front of and / or behind the knife plane. As a result, the thread between the guide edges 51 on the one hand and the knife edge 36 on the other hand is increasingly tensioned, so that the thread on the knife edge 36 forms an angle, preferably an increasingly acute angle. The design and alignment of the knife ensure that the thread has essentially no component of motion transverse to the knife edge.

Das Messer ist also so ausgerüstet und eingerichtet, daß der Schneidvorgang vollständig der Art und Weise entspricht, in der man natürlicherweise einen Faden mit einem Messer durchschneidet.The knife is thus equipped and set up so that the cutting process fully corresponds to the way in which you naturally cut a thread with a knife.
