Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a winding machine for winding a continuously tapered thread-like Spulguts to wind on sleeves with two winding spindles with fixed spindle axes and a removable device. Furthermore, the invention relates to a method for operating a winder when changing the winding process from a winding spindle to another winding spindle.

STATE OF THE ART

Spooled goods such as threads or similar elongate goods such as yarns, wires or ribbons can be continuously supplied by extrusion, spinning or rewinding. By means of winding machines the Spulgut is wound in particular on a sleeve to form a coil for the purpose of forming a coil. In this context, a "continuously" supplied winding material is understood as meaning a provision of a product to be taken in a length which is greater than at least the length of the product to be spooled on a single spool. The finished wound coils can be used for further processing with a decrease in the package or for transport.

In known winding machines, the incoming winding material is fed via one or more fixed or movable rollers of a traversing unit, which has a traversing yarn guide, which performs a traversing movement in a traversing direction which is (largely) oriented parallel to a winding spindle. By a suitable choice of the drive speed or the drive speed curve of the winding spindle itself or a Reibwalzenantriebs the Spool on the one hand and the traversing movement of the traversing yarn guide on the other hand, as well as the stroke of the traversing yarn guide can arbitrary laying patterns, a fixing and / or a reserve winding, a Hubatmung u. Ä. During the installation process be brought about. Modern winding machines have at least two alternately used winding stations, on each of which successively or alternately a coil can be wound. A problem in the continuous supply of Spulguts is the automated continuous change from a winding station with a finished wound coil (hereinafter also "first winding station") to another winding station, in which a winding process to be initiated (hereinafter also "second winding station") , This automated change requires a transfer of Spulguts from the first winding station to the second winding station, the separation of the Spulguts and the trapping and holding the thread end in the region of the second winding station, so that the thread with the onset of winding process "slipping".

Not generic winding machines, eg. According to DE 102 23 484 B4 . DE 10 2006 054 980 B4 such as DE 26 43 271 A1 , have a rotatable turret with which a plurality of winding spindles are rotated together about a turret axis which is oriented parallel to the spindle axes of the winding spindles. On a turret principle based winder require in addition to the drive of the traversing unit, the traversing yarn guide and the winding spindles in addition to the drive of the turret, so that such winder basically mean increased construction and control effort. On the other hand, the non-generic winding machines in Revolverbauart bring the possibility to bring the Spulgut for cutting the Spulguts when changing the winding station in response to the rotational movement of the revolver in operative connection with a separator in the form of a knife by suitable control of the rotational movement of the revolver, see. for example. DE 26 43 271 A1 , Such a possibility of controlling the separation process is not given for winding machines with winding spindles with fixed spindle axes.

By contrast, the spindle axes are arranged stationary in generic winding machines. WO 2008/020070 A1 discloses such a generic winding machine with two separately driven winding spindles, which have fixed, parallel to each other oriented spindle axes. The winding spindles are driven in opposite directions of rotation. A laying of the thread via a traversing unit, in which with respect to a stationary guide a traversing yarn guide can perform a traversing movement parallel to the spindle axes. A supply of Spulguts via one with two fixed and a movable Deflection roller formed dancer control, wherein a drive of a drive unit for the winding spindles takes place in dependence on a deflection of the dancer roll. If a first bobbin is finished wound in a first winding station, the bobbin has to be severed manually and manually wrapped three to five times around a sleeve in the area of the other winding station. Such manual operations are labor-intensive and can pose a risk of injury.

US 5,522,560 discloses a winding machine with two coaxial with each other arranged winding stations. For a change of the winding station finds both a separately controlled and moving transfer element as well as a separately driven and moved knife for separating the Spulguts use.

EP 0 018 577 discloses a winding machine with two winding stations, in which a transfer of Spulguts carried by a separately driven and moving transport device to a deflection hook, which is arranged in the region of the spindle axis of a coil to be wound. The spindle has a gripping device, via which the Spulgut is fed from the Umlenkhaken a sleeve of the coil. The traversing unit used in this publication possesses only one degree of freedom for carrying out the traversing movement of the traversing thread guide.

DE 20 37 282 C3 discloses a winding machine for a wire as Spulgut. Here has a traversing device both a degree of freedom for a traversing movement parallel to the spindle axes and a degree of freedom transverse to the spindle axes in order to transfer the Spulgut from a first winding station to a second winding station. The trapping of Spulguts by a clamping and cutting device requires additional control measures, namely, according to one embodiment, the extension of bolts or castors to deflect the Spulgut in the direction of the clamping or cutting device. Alternatively or cumulatively, the document discloses the equipment of the winding spindles with a degree of freedom of movement in the direction of the spindle axes, so that catching can take place by an axial displacement of the winding spindles.

DE 37 34 478 C2 discloses the use of a movable via a solenoid movable cutting blade, which cuts through the Spulgut when changing the winding station.

OBJECT OF THE INVENTION

The invention has for its object to provide a winder with spindles with stationary spindle axes, in which the automated change of the winding station is simplified with continuously supplied Spulgut taking into account the process reliability. Furthermore, the invention has for its object to propose a respect to the construction and control effort improved method for operating a winder.

SOLUTION

The object of the invention is achieved with a winder with the features of independent claim 1. A further solution of the problem underlying the invention is given by a method having the features of independent claim 13. Further embodiments of such a method according to the invention will become apparent according to the features of the dependent claims 13 to 17.

DESCRIPTION OF THE INVENTION

In the winding machine according to the invention two driven winding spindles are used. Here, the drive of the winding spindles can be done independently or together. Possible is the direct driving of the winding spindles via at least one drive unit, possibly with the interposition of a gear unit, or the indirect driving of the winding spindles or spools via a rubbing roller o. Ä. The winding spindles have fixed and parallel spindle axes which span a Spulspindelebene. It is understood that the winding machine can also have more than two driven winding spindles, which can then be arranged distributed in a common Spulspindelebene or any other way, with two spindle axes each form a Spulspindelebene.

Furthermore, a traversing device is provided according to the invention. This has a freely positionable traversing yarn guide, which is movable in a (approximately) oriented parallel to the spindle axes traversing relative to the spindle axes. This is a first degree of freedom for a movement of the traversing yarn guide - and thus of this guided Spulguts - given. In addition, the traversing device - and with this the traversing yarn guide - transversely to the spindle axes in a direction of movement movable, whereby a second degree of freedom is formed. Here, the second degree of freedom may be a linear or a curved degree of freedom. With the two degrees of freedom a free positioning of the traversing thread guide is given and allows a complex movement of the traversing thread guide in the plane defined by the traversing direction and the traversing plane depending on the control of the traversing device and the traversing thread guide.

• Führung des Spulguts weg von einer ersten, vollständig gewickelten Spule;
• Umlenkung des Spulguts zwischen den beiden Spulstationen;
• Vermeidung, dass ein von der fertig gewickelten Spule weg geführtes Spulgut wieder von dieser Spule gefangen wird;
• Trennung des Spulguts nach oder während des Wechsels von einer fertig gewickelten Spule in einer ersten Spulstation zu einer leeren Spule in einer zweiten Spulstation;
• Umlenken, Verschieben oder Halten des Spulguts derart, dass dieses von einer zu bewickelnden Spule im Bereich einer zweiten Spulstation, der Spulspindel oder zugeordneten Bauelementen gefangen werden kann.

In addition, a change device is provided according to the invention, which finds use in the course of the change of the winding station. Only a few exemplary (alternative or cumulative) functions of such a changer are as follows:

• Guiding the package away from a first, fully wound package;
• Deflection of the material to be spooled between the two winding stations;
• Avoiding that a product being led away from the finished wound reel is again caught by this reel;
• Separating the product to be spooled after or during the change from a fully wound bobbin in a first winding station to an empty bobbin in a second winding station;
• Deflecting, moving or holding the Spulguts such that it can be caught by a coil to be wound in the region of a second winding station, the winding spindle or associated components.

According to the invention, this changing device can not be moved in a controlled manner, so that it is not assigned an actuator. In the simplest case, the changing device is arranged stationary. It is also possible that the changing device is elastically held by the winder or is passively movable.

• eines Aktuators für eine Bewegung einer Wechseleinrichtung,
• eine Ansteuerung einer Transporteinrichtung für den Faden bei dem Wechsel der Spulstation,
• eines Fanghaken u. ä.

gemäß dem Stand der Technik vermieden werden, so dass im einfachsten Fall durch reine Bewegungssteuerung von Changiereinrichtung und Changierfadenführer (u. U. mit geeigneter ergänzender Ansteuerung der Drehbewegung der Spulspindeln) der Transfer von der fertig gewickelten Spule in einer ersten Spulstation zu der noch zu wickelnden Spule in einer zweiten Spulstation bewerkstelligt werden kann. Hierdurch sinken der Bauaufwand, die Bau- und Montagekosten und der Steuerungsaufwand, während gleichzeitig die Prozesssicherheit erhöht werden kann. Andererseits können die Freiheitsgrade der Changiereinrichtung und des Changierfadenführers multifunktional genutzt werden, nämlich einerseits während des Wickelvorgangs einer Spule und andererseits für den Transfer des Spulguts zwischen den Spulstationen.Finally, according to the invention, a control device is provided, which also means a distributed control device formed with two or more control units. The control device is suitably designed and responsible for the fact that the winding material for changing the winding station is "picked up" by a fully wound coil on the first winding spindle, is brought into operative connection with the changing device, where this is deflected, and an empty sleeve on one second winding spindle or one of the second winding spindle associated holding, catching or clamping device is supplied. For this purpose, the control device coordinates the movement of both the traversing device transverse to the spindle axes as well as the traversing yarn guide parallel to the spindle axes. Thus, according to the invention, the mandatory requirement

• an actuator for a movement of a changing device,
• a control of a transport device for the thread during the change of the winding station,
• a fishing hook u. ä.

According to the prior art, so that in the simplest case by pure motion control of traversing and traversing yarn guide (u., With suitable complementary control of the rotational movement of the winding spindles) of the transfer from the finished wound coil in a first winding station to be wound yet Spool can be accomplished in a second winding station. This reduces the construction costs, the construction and assembly costs and the control effort, while at the same time process reliability can be increased. On the other hand, the degrees of freedom of the traversing device and the traversing yarn guide can be used multifunctional, namely on the one hand during the winding process of a coil and on the other hand for the transfer of Spulguts between the winding stations.

According to a further proposal of the invention, the changing device is arranged in projection in the Spulspindelebene between the spindle axes, but in the direction of the spindle axes in front of or behind the sleeves. This has the advantage that the changing device does not interfere with the winding process, but only in interaction with the Spulgut occurs when the traversing yarn guide is placed specifically outside of the gap between the two coils.

In a further embodiment of the invention, the said degrees of freedom of traversing device and traversing yarn guide are used to bring under suitable control by the control device of the traversing yarn behind the changing device in a catching position. In this catching position, the path of the product to be spooled between the changing device and the traversing yarn guide passes through a catching area of the holding, catching or clamping device, so that the material to be taken up can be caught in the region of the second winding station. While it is quite possible that the Spulgut is caught by the holding, catching or clamping device (hereinafter also "catcher") at the time at which the traversing yarn guide reaches the catch position, even after the traversing yarn guide has reached the catching position Delayed movement of the catching device in Direction of the Spulguts done, for example by the catcher is rotated with the winding spindle in the direction of Spulguts.

In a further embodiment of the winding machine according to the invention the Spulgut between the finished wound coil and the empty coil in a first approximation in projection in the Spulspindelebene is guided V-shaped. In this case, the changer is located at the vertex of the V. About this V-shaped guidance of the Spulguts the Spulgut between the winding stations can be led out of the space between the two coils.

• Für die Abnahme des Spulguts von der fertig gewickelten Spule kann es von Vorteil sein, wenn die erste Umlenkfläche nicht weit vor oder hinter dem Zwischenraum zwischen den beiden Spulen angeordnet ist. Grund hierfür ist einerseits, dass mit einer Vergrößerung des Abstands von dem Zwischenraum der Winkel des Spulguts bei der Entnahme zur Umfangrichtung der fertige gewickelten Spule zunimmt, so dass sich der Verlegewinkel der letzten Wicklung auf der Spule verändern kann. Gravierender ist aber, dass mit einer Vergrößerung des Abstands der ersten Umlenkfläche von dem genannten Zwischenraum die Gefahr steigt, dass ein Spulgut, sei es vor oder nach der Durchtrennung desselben im Rahmen des Wechsels der Spulstation, wieder von der ersten Spule gefangen wird und/oder ein unerwünschtes Aufwickeln des Spulguts auf der der Spule abgewandten Seite eines Flansches von der Spulspindel der ersten Spulstation erfolgen kann.
• Andererseits kann es für das Fangen des Spulguts durch die leere Spule im Bereich der zweiten Spulstation erforderlich sein, dass die zweite Umlenkfläche, über die vorgegeben wird, wie weit das Spulgut nach außen verlagert wird und in den Fangbereich der Fangeinrichtung gelangt, einen Mindestabstand in Richtung der Spindelachsen von dem Zwischenraum zwischen den Spulen hat.

While it is possible, for example, in a simple embodiment, that the changing device is designed as a simple deflecting bolt or deflection roller, so that a deflection surface is given in accordance with a circular arc, the invention proposes in a further embodiment, that the changing device has two deflection surfaces over which the Spulgut is deflected in opposite directions. Here, the deflection surfaces are offset from one another in the direction of the spindle axes. The invention has recognized that such a configuration can be advantageous for a variety of reasons:

• For the removal of the Spulguts of the finished wound coil, it may be advantageous if the first deflection is not far in front of or behind the gap between the two coils. The reason for this is on the one hand that with an increase in the distance from the intermediate space of the angle of the Spulguts at the removal to the circumferential direction of the finished wound coil increases, so that the laying angle of the last winding on the coil can change. But more serious is that with an increase in the distance of the first deflection of the said gap increases the risk that a Spulgut, be it before or after the separation of the same as part of the change of the winding station, again caught by the first coil and / or An unwanted winding of the Spulguts on the side facing away from the coil of a flange of the winding spindle of the first winding station can take place.
• On the other hand, it may be necessary for catching the Spulguts by the empty bobbin in the region of the second winding station that the second deflection over which is given, how far the Spulgut is displaced outwards and in the capture area of the Catching device has a minimum distance in the direction of the spindle axes of the space between the coils has.

These requirements can be taken into account by the embodiment according to the invention with two deflection surfaces arranged offset from each other.

Basically, a severing of the Spulguts after catching the same in the region of the second winding station in any known manner and at any location is possible. For a further embodiment of the invention, an automatic separation of the Spulguts in the area of the changing device, so that changing device and separator are arranged spatially compact.

While it is quite possible that the separator is movable, possibly controlled by an actuator, the separator is stationary in a further embodiment of the invention. It is also possible that the separating device is an integral part of the changing device, whereby a particularly compact design is created.

For a particularly simple structural design of the changing device, this is formed with two rods which are oriented at an acute angle to each other. For example, this acute angle is 10 ° to 30 °. The Spulgut is introduced into the intermediate space formed between the two rods and threaded therethrough, which takes place by controlling the traversing device and the traversing yarn guide according to said two degrees of freedom by the control device. In this case, partial jacket surfaces of the two rods can each form the aforementioned two deflection surfaces with the resulting advantages, whereby the offset of the two deflection surfaces can be predetermined via the alignment of the two rods and the diameter thereof. On the arrangement of the two rods at an acute angle, the process reliability of the winding machine according to the invention can be further increased, since the V-shaped rods can form a kind of insertion aid.

In a further embodiment of this solution, the separation device in a region of the rods, in which the distance between the rods is reduced from each other, arranged so that the Spulgut on the V-shaped rods "funnel-like" the separator can be supplied, which is beneficial to process safety ,

Is the Spulgut with the changing device in operative connection, fed to the first winding station and u. U. already caught by the capture device of the second winding station, the Spulgut must be severed, including a relative movement between the separator and the Spulgut must be brought about. While this u. U. according to the prior art can be brought about by an actuated actuated movement of the separator, an advantageous solution according to the invention is that the relative movement is caused by the rotation of the catcher of the second winding station with the rotation of the winding spindle. Thus, so to speak, the catching device in the course of rotation of the winding spindle, in particular for a defined angle of rotation or rotation angle range, the tensioned Spulgut on the separator until the Spulgut is severed. Thus, the capture device is designed multifunctional, since this not only serves to hold, catching and / or clamping the Spulguts, but is responsible without the need for additional measures for effecting the separation process, including the already existing rotational movement of the winding spindle can be used.

In a method according to the invention, the control effort and u. U. also the construction cost can be reduced by the Spulgut by exclusive control of the traversing device, the traversing yarn guide and / or the drive of the winding spindles after completion of a winding on a first winding spindle in the region of a first winding station of this winding on the changing device in the region of the second Winding spindle is brought. With the two degrees of freedom of the traversing device and the traversing yarn guide, the required complex movement of the traversing yarn guide and the material to be taken up can be brought about without additional actuators, catching elements, transport elements and the like. Ä. Are required. In addition, u. U. also the cutting of the Spulguts exclusively by controlling the traversing device, the traversing yarn guide and / or the drive of the winding spindles.

In a further embodiment of this method according to the invention, after the completion of the first winding, the control of the traversing yarn guide is such that the traversing yarn guide is moved in traversing direction in front of or behind the first winding, so that the winding material can come into operative connection with the changing device. Following this, the control of the traversing yarn guide takes place in such a way that the traversing yarn guide is moved back in traversing direction. During this changing direction of movement of the traversing yarn guide, the traversing device is controlled in a traversing direction, ie transverse to the traversing direction of the traversing yarn guide such that the traversing yarn guide is moved from a surrounding area of the first winding spindles into the surrounding area of the second winding spindle. By controlling the traversing yarn guide and traversing device can thus u. U. required complex movement are generated, during which the Spulgut is "picked up" of the full roll, can interact with the changing device and the second winding station is supplied with an empty bobbin.

A further embodiment of the method according to the invention pays particular attention to the holding, catching and / or clamping of the product to be spooled with or after movement thereof into the region of the second winding station: for this purpose a holding, catching or clamping device is rotated with the second winding spindle. The operative connection between the Spulgut and the holding, catching or clamping device is brought about by a rotation of the same takes place to a predetermined angle of rotation or angle of rotation range. At the same time or offset in time, the traversing yarn guide is moved into a position, so that the winding material extending between the changing device and the traversing yarn guide is arranged in a catching area of the holding, catching or clamping device.

In a further embodiment of the invention, separate actuators and their control for a severing of the Spulguts can be avoided. This is done by causing a relative movement between a stationary separating device and the Spulgut for severing the Spulguts exclusively by the rotational movement of the winding spindle.

Advantageous developments of the invention will become apparent from the claims, the description and the drawings.

DESCRIPTION OF THE FIGURES

The schematic figures show a winding machine 1 with a vertically oriented base plate 2, which is arranged stationary and the support or storage of other components of the winder 1 is used. In the case of horizontal orientation (and thus vertical alignment with the base plate 2), two parallel winding spindles 3, 4 are rotationally driven by drive units (not shown) directly or indirectly about their spindle axes 5, 6. In each case at least one sleeve flange 7, 8 is a one-piece or multi-piece non-rotatable component of the winding spindle 3, 4. In the region of the radially outer circumferential surfaces of the sleeve flanges 7, 8 is a clamping, catching or holding device 9, 10 (hereinafter also "catcher "), which is thus also rotated with the rotation of the winding spindles 3, 4. Sleeves 11, 12 are respectively attached to the winding spindles 3, 4 with the possibility of transmitting the drive movement of the winding spindles 3, 4 on the sleeves 11, 12th

Displaceable in a traversing direction 13 a traversing device 14 is guided relative to the base plate 2. In this case, the travel direction 13, as in Fig. 1 shown to be a translational degree of freedom. It is also possible that it is a curved degree of freedom. In any case, the direction of travel 13 is oriented transversely to the spindle axes 5, 6. For the movement of the traversing device 14 in the direction of travel 13 is controlled by a control device not shown, also not shown actuator responsible, in which it is an arbitrary actuator, such as an electric Actuator, a hydraulic actuator or the like can act. The thus moved traversing device 14 is formed with a guide unit or rail 15 which extends substantially parallel to the spindle axes 5, 6. Opposite the guide unit 15 is via a further, controlled by the control device and not shown actuator a traversing yarn guide 16 in a traversing direction 17, which is oriented parallel to the spindle axes 5, 6, movable. The traversing direction 17 and the vertically oriented for this direction of travel 13 allow for the illustrated translational degree of freedom of the traversing device 14 relative to the base plate 2 any movement of the traversing yarn guide 17 in a plane parallel to the plane according to Fig. 2 is oriented, with any curve of the movement depending on the actuation of the actuators by the controller. About the iridescent in traversing direction 17 movement is carried out the continuous laying of a Spulguts 18 on the sleeve 11 in the region of a first winding station 19 and after a change to a second winding station 20 on the sleeve 12. A continuous supply of Spulguts 18 takes place for the illustrated embodiment an example fixed roller 21 and the traversing yarn guide 16 to be wound coil, so the sleeve 11, 12 or an already partially wound winding 22, 23. A guide and limitation of the winding 22, 23 can be done by the sleeve flanges 7, 8.

The inventive winding machine 1 has a changing device 24. For the illustrated embodiment, the changing device 24 is formed with a deflection device 25 and a separator 26 as a structural unit. The deflection device 25 is formed with two rods 27, 28, which in the plane according to Fig. 1 V-shaped and whose longitudinal axes form an acute angle 29. The acute angle 29 is preferably 10 ° to 30 °. The V-shaped deflection device 25 is open in the direction of the traversing device 17 and the traversing yarn guide 16. In the connecting region of the two legs of the V, ie in the lower end region of the rods 27, 28, the separating device 26 is arranged, which is formed in the simplest case in the form of a cutting blade, the blade facing up and between the two rods 27, 28 in parallel according to the drawing level Fig. 1 extends. In Fig. 2 It can be seen that the V-shaped arranged rods 27, 28 span a plane which is oriented parallel to the base plate 2. Here, this plane corresponds approximately to the plane in which the two sleeve flanges 7, 8 are arranged. The changing device 24 is arranged centrally between the two spindle axes 3, 4. The spindle axes 3, 4 clamp a winding spindle plane 30. The traversing device 14 with traversing yarn guide 16 is slightly, for example with a distance of 0.5 cm, 2 cm, 4 cm or 8 cm, above the changing device 24. The upper end portion of the rods 27, 28 corresponds approximately to the highest position in which the catching devices 9, 10 with rotation of the winding spindles third , 4 can be spent. The reference numerals for the previously described components are only in the Fig. 1 and 2 shown. With the Fig. 1 to 12 are shown with pairs of a front view (odd figure numbers) and an associated plan view (even figure numbers) six process steps for a change of the winding operation from the first winding station 19 to the second winding station 20th

Fig. 1 and 2 show the end of the winding process of a coil in the region of the first winding station 19 with the completion of the roll 22. Here, the finishing of the roll 22 depending on the weight of Spulguts, be determined by a detected length of the Spulguts in the winding 22 or timed.

For the next step proceeds according to 3 and 4 First, the traversing device 14 in the direction of travel 13 such that the traversing yarn guide is located centrally between the spindle axes 3, 4. At the same time or subsequently, the traversing yarn guide travels in the traversing direction 17 along the guide unit 15 in traversing direction 17 in the direction of the base plate 2 and the changing device 24, until the in Fig. 4 apparent position is reached, in which the traversing yarn guide 16 is in viewing direction of the base plate in the direction of traversing 17 in front of the coils, the sleeve flanges 7, 8 and the changing device 24. Since the traversing yarn guide 16 is arranged above the changing device 24, it can pass through the changing device 24. During this movement, the Spulgut extends from the bottom of the coil up to the traversing yarn guide, with increasing movement of the traversing yarn guide 16 in the direction of the base plate, the Spulgut can continue to enter from above into the V-shaped deflector 25. Thus, the Spulgut 18 is "threaded" in the changing device 24, between the two rods 27, 28. In Fig. 4 can be seen that the first winding station 19 facing rod 27 finally comes to rest on the Spulgut 18 with a deflection 31, in the region of which a deflection of the Spulguts comes, namely in the direction of the first winding station away a deflection in the counterclockwise direction Fig. 4 , With movement of the traversing yarn guide 16 in the traversing direction of the deflection 31 moves u. U. in the direction of the longitudinal axis of the rod 27 down. In 3 and 4 is the traversing yarn guide 16 centrally between the two spindle axes 3, 4 in an end position in Traversing direction 17, which is located furthest in front of the coils and closest to the base plate 2.

In the next step, the traversing yarn guide is not moved in traversing 17. Rather, a movement of the traversing device 14 takes place in the direction of travel 13 with a sense of direction away from the first winding station until the in FIGS. 5 and 6 shown position of the traversing yarn guide 16 is reached. In this comes the Spulgut with the deflector 25 (also) in operative connection with a deflection region 32, in which the Spulgut 18 in the direction of the first winding station 19 away in the illustration according to Fig. 6 can be deflected clockwise. By said movement in the direction of travel 13, the winding material 18 in the deflection device 25 moves even further downwards in the direction of the separating device 26, although a residual distance between the separating device 26 and the winding material 18 remains (cf. Fig. 3 and 5 ).

In a next process step (cf. FIGS. 7 and 8 ), the traversing yarn guide 16 is brought into a catching position 33, which is predetermined such that a region 34 of the Spulguts 18 extending between the changing device 24 and the traversing yarn guide 16, with a small distance 35, for example, 0.5 cm, to the lateral surface of the sleeve flange 8 extends past. This is the case with a rotation angle 36 of the sleeve flange 8, which correlates approximately with a 10 o'clock position for the illustrated embodiment. If now takes place a common rotational movement of the winding spindle 4 with sleeve flange 8 and catcher 10, the catcher 10 also moves to the angle 36. Upon reaching the angle 36, the catcher 10 can catch, clamp and / or hold the Spulgut. With subsequent further movement of winding spindle 4, sleeve flange 8 and catcher 10 takes the catcher 10 the Spulgut with down (see. FIGS. 9 and 10 ). While previously the Spulgut 18 still had a (small) distance from the separator 26, the movement of the Spulguts down with the catcher 10 causes the Spulgut 18 is pulled against the separator 26. With sufficient clamping force of the Spulguts 18 and increasing movement of the catcher 10 down it comes to severing the Spulguts 18 through the separator 26. The severing of the Spulguts takes place at a second angle of rotation 37. After severing the Spulguts 18 is the vacant end of the Spulguts 18 but still held by the catcher 9. With further drive of the winding spindle 4 with associated components and suitable traversing movement of the Changierfadenführers 16 can then take place a winding of the roll 23 in the region of the second winding station 20 (see. FIGS. 11 and 12 ).

It will be apparent to those skilled in the art that a change from a second winding station 20 to a third winding station, not shown, may occur accordingly. Also possible is a return to the first winding station 19, when the winding 23 is completed in the region of the second winding station 20 and the coil is removed with the finished winding 22 in the first winding station 19 and replaced by a new empty sleeve 11. For the illustrated embodiment, the winding spindles 3, 4 are driven in opposite directions, wherein in the region of the winding spindle 3, a supply of Spulguts 18 takes place in the region of the bottom, while this is done for the winding spindle 4 in the region of the top.

In particular in Fig. 10 the function of the deflection regions 31, 32 can be seen: the deflection region 31 of the rod 27 facing the first winding station 19 should be arranged so far in the direction of the gap between the two coils and away from the base plate 2 that the deflection region 31 ensures that that the laying angle of the Spulguts 18 is not changed undesirable in the last winding. On the other hand, the deflection area 31 ensures that no undesired interaction between the winding material 18 and the sleeve flange 7 occurs or that the winding material 18 is caught by the catching device 9 in the region of the first winding station 19 in an undesired manner. On the other hand, during the catching of the winder 18 by the capture device 10, the deflection region 32 provides a local boundary condition for the region 34, which must be displaced so far in the direction of the base plate 2 that the winder 18 in the region 34 is sufficiently close to the sleeve flange 8 can be passed so that the catcher 10 can catch the Spulgut. In order to fulfill these two tasks of the deflection regions 31, 32, a suitable dimensioning of the diameters of the rods 27, 28 may be required. It is also possible that the arrangement of the deflecting device 25 from the horizontal arrangement in Fig. 10 is rotated counterclockwise, whereby the distance of the deflection region 31 is increased by the base plate 2, while the distance of the deflection region 32 is reduced by the base plate 2. But this is u. U. disadvantageous if a return change from the second winding station 20 to the first winding station 19 should be made. For example, in such a case, two deflection devices 25 and 25a, which are each formed with a pair of rods 27, 28, 27a, 28a, may be arranged one behind the other in traversing direction 17. In this case takes place for a change from the first winding station 19 to the second winding station 20, a deflection in a deflection region 31 of the rod 27 of the first deflection device 25, while the deflection region 32a is formed by the rod 28a of the second deflection device 25a. For the return change from the second winding station 20 to the first winding station 19, the other rods 27a, 28 of the pairs of deflection devices 25, 25a then form the deflection regions 31a, 32.

The person skilled in the art will recognize that various possibilities of movement for the traversing yarn guide 16 within the scope of the invention are possible during the change. The only factor is that during the change by the traversing yarn guide 16, the Spulgut 18 is brought into operative connection with the changing device 24, in particular the Spulgut 18 is threaded through the deflection device 25. For this purpose, the traversing yarn guide 16 must be in the end position according to Fig. 4 be spent, for which the traversing yarn guide 16 is located on the side facing away from the bobbins of the changing device 24 when viewed in the direction of the traversing 17. For example, a movement of the traversing yarn guide 16 can take place in accordance with a V, wherein the tip of the V is the aforementioned end position of the traversing yarn guide 16. The two legs of the V can have different angles to the traversing direction 17 and also be formed arbitrarily curved.

The rods 27, 28 may be optimized for contact with the Spulgut 18 and a sliding relative movement, for example with a corresponding sliding coating. It is also possible that the rods 27, 28 are formed with rotatably mounted sleeves.

The catching devices 9, 10 may have an elastic element, via which a clamping of the Spulguts 18 can take place. The sleeve flanges 7, 8 have a diameter which is preferably slightly larger than the maximum diameter of the thread winding 22, 23 to be created, so that the catching devices 9, 10 are arranged at a diameter which is only slightly larger than that of the to be created Wraps 22,23.

In an alternative embodiment, the first according to Fig. 8 Rather, the traversing yarn guide 16 is here moved in the direction of the base plate remote stroke end and moved the traversing device 14 in the position for later winding the empty sleeve 12. In this position can also upon rotation of the winding spindle 4 with catching device 10, the winding material is not yet caught by the catching device 10. By a subsequent lifting movement of the traversing yarn guide 16 in the direction of traversing 17 on the base plate 2 can then specifically 18 to be approximated to the sleeve flange 8 until the winding material 18 is located in a diameter range corresponding to the capture area 38 of the capture device 10. If the catcher 10 once caught the Spulgut 18, there is an accelerated decrease of Spulgut 18 of the traversing yarn according to the speed profile of the winding spindle 4. If the speed of the winding spindle 4 is not regulated down or can not be done down regulation to a sufficient extent, can compensate in the short term take place by controlling the traversing yarn guide 16 in traversing 17th

After severing the Spulguts 18 in the region of the separator 26, the coil is braked in the region of the first winding station 19 and brought to a standstill, so that a change is possible against an empty shell.

The sleeve flanges 7, 8 may be arranged at a distance 39, for example of at least 3, 5 or 10 cm from the base plate 2 spaced to provide sufficient space for movement of the traversing yarn guide 16 behind the changing device 24 with the associated introduction of the Spulguts18 of at the top of the changer 24.

It is also possible that the traversing device 14 has a further actuated actuated degree of freedom, which is oriented vertically to the direction of travel 13 and the traversing direction 17.
