Description

Apparatus and method for melt spinning, stripping, treating and winding a plurality of synthetic threads

The invention relates to a device for melt-spinning, stripping, treating and winding a plurality of synthetic threads according to the preamble of claim 1 and a method for melt-spinning, stripping, treating and winding a plurality of synthetic threads.

A generic device and a generic method are known for example from DE 44 16 136 Al.

In the known device and the known method, a plurality of spinnerets are held in a series arrangement in a spinning device. Through each of the spinnerets, a plurality of filaments are extruded as a filament and cooled by a cooling device arranged below the spinneret by a cooling medium. After the filaments have cooled, the filament bundle produced per spinneret is joined together by a preparation device. In this case, a cohesion between the filaments to a thread is achieved by a preparation. The threads are drawn off continuously from the spinnerets as a drum stock, by means of a draw-off element arranged below the cooling device, and after a treatment, are wound up into respective bobbins.

Since the guide distance and the treatment distance of the threads at trigger and treatment is substantially smaller than the thread spacing in the spinning device, the threads must be very strongly deflected and brought together in the transition from the spinning device to the trigger member. The deflection of the threads is dependent on the distance of the threads in the spinning device and the number of parallel side by side spun threads. In this case, maximum permissible deflection angles are to be observed, in order not to obtain too large differences in the loop in the thread guide, in particular in the outer threads, which are forcedly frequently lead to physical differences in the threads produced. Derar¬ term allowable deflections in the range of less than 7 ° can be reduced accordingly only by a correspondingly long zone between the spinning device and the trigger member. La practice, however, the smallest possible distance between the convergence points of the filament bundles and the position of the trigger member is desired, so that a Fadenführang with different Um¬ schlingungen when merging the yarn sheet are difficult to avoid. Furthermore, there is the desire to keep the Bau¬ height of the plant limited for cost and handling reasons. However, this causes the problem that the threads are exposed to uneven conditions when entering a treatment device with respect to the thread tension and the thread conclusion.

It is an object of the invention to provide an apparatus and a method for melt spinning, stripping and winding a plurality of synthetic threads of the type mentioned, in which or in which the parallel spun yarns are feasible despite the merging to a narrower thread pitch as possible under uniform conditions ,

It is also an object of the invention to develop a generic device and a generic method in such a way so that even with a Viel¬ number of parallel-spun yarns a thread guide for realizing kom¬ pakter constructions of spinning plants are possible.

A further object of the invention is to realize the smallest possible deflection angle in the transition from a spinning device to a treatment device when using a plurality of spinning nozzles.

The object is achieved by a device for melt spinning,

Stripping, treating and winding a plurality of synthetic threads with the features of claim 1 and by a method for melt spinning, Stripping, treating xmd winding several synthetic threads solved with the features of claim 16.

The invention is characterized in that the merging of the individual spun threads into a common thread group to be treated takes place in several stages. For this purpose, several Abzugsor¬ gane are provided below the cooling device, each of the trigger members is assigned a group of spinnerets. Thus, advantageously, the majority of the spun threads are divided into two or more groups, which are each deducted by separate trigger members. The take-off members cooperate with a downstream treatment member in such a way that, after the groups of threads have been removed, all the threads can be guided together as a group of threads through the treatment member. A significant advantage of the invention is that even with a plurality of simultaneously spun yarns, the distance between the arranged substantially at a height convergence points of the filament bundles and the position of the trigger members can be brought to a technically feasible minimum distance. The point of convergence of a filament bundle is the position in the thread run of a thread, in which the filament bundle are brought together to form the thread. The zone between the convergence points of the FIIa ^'ment flock and the positions of the removal members obliquely through each of the threads, so that this zone is not suitable for collective treatment of the threads and thus may be carried out according to the invention particularly short.

In order to obtain as uniform as possible deflections and wraps within the group of threads, the withdrawal process according to an advantageous development of the invention are preferably arranged symmetrically below the respectively zuge¬ arranged groups of spinnerets.

In a further preferred embodiment of the invention, the threads are after extruding in a common spinning plane and for treatment in a treatment level oriented substantially orthogonal to the spider plane. As a spinning plane in this case the thread running plane is designated, which is predetermined by the spinnerets of the spinning device. The treatment level represents the common threadline of all threads defined by the treatment organ. This results in additional freedom in the arrangement of Ab¬ zugsorgane that can lead the groups of threads either parallel to the spinning plane or parallel to the treatment level or in an intermediate level.

In this case, the take-off members are preferably arranged in front of the treatment members in such a way that each thread can be guided with equal thread turns. This ensures a high degree of uniformity in the production of the synthetic threads.

In order to enable a parallel intake of the groups of threads in the draw-off members, each draw-off member is advantageously provided with a collection thread guide through which the threads can be guided from a pitch of the spinnerets into a preferred narrow guide spacing.

In order for an intensive thread closure to prevail on the thread, in particular for the treatment of the threads, it is proposed according to a preferred development of the invention to arrange a predorting device between the collecting thread guides and the withdrawal members. The preparation application lost due to the deflection or uneven preparation application can thus be compensated or evened out. Likewise, the thread tension is equalized before casserole on the trigger on the parallel threads.

The take-off members are preferably formed by a respective driven godet, the godet drives of the godets being synchronously controllable. In order to avoid any differences in the guidance of the groups of threads 2x1, the godet drives of the godets are advantageously controlled by a group converter.

However, it is also possible that the godets in each case an overroller is zugeord¬ net, so that the threads the godets and the overflow roll umschlin¬ multiple times. This can also be higher take-off forces for stripping the respective groups of threads reach.

The treatment of the yarn bundle which has been brought together after peeling to produce parallel yarns can, alternatively or in combination, be stretching, tanning, tempering or a folding. Preferably, the threads are stretched before winding in different ways, so that as treatment organ to the trigger preferably a driven draw godet for example, for the production of POY yarns or at least one driven godet duo for drawing the threads is arranged.

However, the treatment device can also be formed solely by means of a tangling device which contains a plurality of thread treatment channels with a treatment interval of <10 mm, which leads to correspondingly large occupation densities, particularly in the case of upstream or downstream guides.

Preferably, the Tangeleinrichtung is upstream in the yarn path of the draw godet, so that a favorable for winding the threads thread tension is adjustable and selectable. The arrangement of the tangle device in the yarn path in front of the stretched pallets also has the advantage that in the case of single or multiple looped godets, the protruding lengths remain relatively low due to the small spacing between the threads.

For the production of microfilaments with high uniformity of the physical properties, a cooling device is furthermore proposed which has a blow candle per spinneret. In this case, a radially directed from the inside outward cooling air flow for cooling the annularly guided filament bundle of one of the spinnerets is generated by the blow candles.

In this case, the filament bundle can lead both to a thread or to several threads. For the formation of a plurality of filaments from a filament bundle, preferably a preparation device is used, which has a plurality of preparation thread guides per spinneret. Thus, the annular filament bundle can be converted into several threads.

Some exemplary embodiments of the device according to the invention and the method according to the invention will be described in greater detail below with reference to FIGS. 1 to 3.

They show:

Fig. 3 shows schematically a further embodiment of the device according to the invention

FIG. 1 schematically shows a first exemplary embodiment of a device according to the invention for melt-spinning, stripping, treating and winding up a plurality of synthetic threads. To produce a plurality of threads, the apparatus has a spinning device 1, a cooling device 2 arranged downstream of the spinning device 1 and a winding device 3 provided for winding the threads. The spinning device 1 has a plurality of spinnerets 8.1 to 8.6 arranged parallel to one another. The spinnerets 8.1 to 8.6 are held on the underside of a heatable spinnable bar 7. The spinning beam 7 contains a plurality of spinning pumps and melt distributors, not shown here, which are connected via a melt feed 12 to a melt source, for example an extruder. The spinnerets 8.1 to 8.6 have on their underside an annular arrangement of a plurality of Düseribohrungen through which a plurality of fi laments can be extruded.

Below the spinning device 1, a cooling device 2 is provided, which is formed by a plurality of blow candles 10.1 to 10.6 within a cooling shaft 34. The Blaskerzen 10.1 to 10.6 are centrally associated with the spinnerets 8.1 to 8.6, wherein the extruded through the spinnerets 8.1 to 8.6 filaments as a ring-shaped filament bundle enclose the respectively associated Blaskerzen 10.1 to 10.6 shell-shaped. The undersides of the blow candles 10.1 to 10.6 are connected to a source of cooling air.

Immediately below the cooling device 2, a preparation device 4 is provided which has a plurality of preparation fibers 11.1 to 11.6 associated with the spinnerets 8.1 to 8.6.

Below the preparation device 4 are provided with spaced apart ange¬ arranged Abzugsorgane 5.1 and 5.2. The trigger member 5.1 is in this case formed by a first galette 13.1, which is associated with the spinnerets 8.1, 8.2 and 8.3 in the vertical direction, to subtract a first group of threads 35.1 from the spinning device 1.

The second take-off element 5.2 is formed by a second godet 13.2, which is assigned in the vertical direction to the spinnerets 8.4, 8.5 and 8.6 in order to remove a second group of threads 35.2 from the spinning device 1. The godets

13.1 and 13.2 are driven by the godet drives 14.1 and 14.2. to Control of the godet drives 14.1 and 14.2 is a group converter 15 vorge see.

The trigger member 5.1 is preceded by a first Fadenumlenkstange 16.1, a Sammelfaden- leader 17.1 and a Vortangeleinrichtung 18.1. The second draw-off element 5.2 is associated with a second Fadenumlenkstange 16.2, a Sammelelfadenrαhrer 17.2 and a Vortangeleinrichtung 18.2.

On the side next to the draw-off elements 5.1 and 5.2, a treatment member 6 is provided, which is formed by a main tucking device 21 and draw godet 19. Here, the Haupttangeleinrichtung 21 in the yarn path is directly the

Streckgalette 19 upstream. To the end of the partial looping at the

Streckgalette 19 guided threads a drain guide 22 is provided by which the threads are held at the expiration of the draw godet 19 to a treatment distance. The draw godet 19 is driven by a godet drive 14.3.

Below the treatment member 6, the winding device 3 is arranged. The winding device 3 has in the thread running direction a traversing device 24, a pressure roller 25 and a first winding spindle 26.1. On the winding spindle 26.1, the threads are wound into coils 27. The winding spindle 26.1 is held on a turntable 28 which carries a second winding spindle 26.2 offset by 180 ° relative to the winding spindle 26.1. For thread guidance of the traversing device 24 per thread each a head thread guide 23 upstream.

The device shown in Fig. 1 is particularly suitable to produce so-called POY threads. For this purpose, at each of the spinnerets 8.1 to 8.6, a given polymer melt is extruded into a respective group of filaments 9.1 to 9.6. Each of the filament bundles 9.1 to 9.6 is cooled by a cooling medium flow directed radially from the inside through the blowing candles 10.1 to 10.6 and, after cooling by a respective preparation yarn guide 11.1 to 11.6, is cooled. nem thread together. The threads extruded through the spinnerets 8.1 to 8.3 constitute a first group of threads 35.1, which are pulled off the spinning device 1 by the draw-off element 5.1. The spinnerets 8.4 to 8.6 represent a second group of threads 35.2, which are withdrawn from the spinning device by the second withdrawal element 5.2. The threads of the two groups 35.1 and 35.2 are guided in a common spinning plane during the merger of the filament bundles. In contrast, the yarn bundle 36 formed by all yarns is guided in the treatment member 6 into a treatment plane which is oriented essentially orthogonally to the spinning plane. For this purpose, it is necessary that the threads are rotated from the transition from the spinning device 1 or the preparation device 4 in the treatment member 6 by approximately 90 °.

In order to lead the threads of the first group 35.1 out of the spinning plane, the first take-off element 5.1 is preceded by a thread deflection bar 16.1 and a collecting thread guide 17.1. By means of the collecting yarn guide 17.1, the threads of the first group 35.1 are brought into a guiding distance from a pitch which is defined by the spacing of adjacent spinnerets 8.1 and 8.2. From the collecting thread guide 17.1 to the treatment member 6, the guide distance between the threads remains substantially constant. Before the threads run from the pile thread guide 17.1 onto the first godet 13.1, the individual threads are twisted in the preliminary setting device 18.1. Such a pretanning device is known, for example, from DE 100 23 910 A1, so that reference may be made to the cited document at this point.

In order to guide the second group of threads 35.2 out of the spinning plane, the second thread deflection bar 16.1 and the second group thread guide 17.2 are provided. In this case, the threads of the second group 35.2 are also brought by the collecting thread guide 17.2 from the pitch into a guiding distance. To pull off the two groups of threads 35.1 and 35.2, the godets 13.1 and 13.2 are driven at identical peripheral speeds. For this purpose, the godet drives 14.1 and 14.2 are controlled by a group converter 15.

The threads of both groups 35.1 and 35.2 are deducted by the subsequent treatment organ 6 from the deduction processes 5.1 and 5.2. For this purpose, the draw godet 19 is driven at a circumferential speed, which is preferably somewhat larger than the peripheral speed of the godets 13.1 and 13.2. The threads of the first group 35.1 are guided, after partial looping of the gilette 13.1, directly to the treatment member 6. The second group of threads 35.2, after partial looping of the second godets 13.2 and after partial wrapping of the first godet 13.1, are guided to the treatment member 6, so that after the first godet 13.1 the threads of the first group 35.1 and the second group 35.2 have a common thread group 36 form. The angles of wrap of the threads of the second group 35.2 on the godets 13.2 and 13.1 are equal to the angle of wrap of the first group of threads 35.1 on the godet 13.1. Thus, all threads are guided at entry into the yarn sheet 36 with identical wrap angles.

The threads of the yarn sheet 36 are first vortexed in parallel in the Haupttangeleinrichtung 21 side by side. For this purpose, the Haupttangeleinrichtung 21 a plurality of parallel thread treatment channels, in which a Druck¬ air supply leads to turbulence of the threads. The threads are guided in this case at a treatment distance, which is preferably <10 mm. The treatment distance here can preferably be selected equal to the guide distance, as it sets between the threads on the trigger members 15.1 and 15.2. In parallel run the yarn sheet 36 is guided by the draw godet 19 with Teilum¬ schlingung and spread after passing through the drain thread guide 22 to the individual winding units of the take-up winding device 3. In the winding device 3, the threads of the yarn sheet 36 are wound parallel to each other zxi each a coil 27. For this purpose, the Aufwickelein¬ direction 3 six adjacent winding units, each of the threads is guided over a head thread guide 23, the traversing device 24 and the pressure roller 25 to a coil 27.

The apparatus shown in Fig. 1 for melt spinning, stripping, treating and winding a plurality of synthetic threads is characterized by an extremely compact design with low height. Through the use of several extraction members, the zone between the convergence points of the filament bundles, which are defined by the individual preparation yarn guides 11.1 to 11.6, and the positions of the collecting yarn guides 17.1 and 17.2 can be reduced to a minimum without obtaining undue deflections of the yarn. Despite the division of the threads into several groups for stripping, an advantageous treatment of the threads as a thread group remains. This can be achieved for treatment guide distances between the threads, which allows a compact design of individual units. Guide distances in the range of <10 mm can be realized easily. The symmetrical division and deflection of the threads for stripping also guarantees a uniform quality of all threads.

FIG. 2 shows a further exemplary embodiment of the device according to the invention for carrying out the method according to the invention. The structure and function of the embodiment is substantially identical to the vor¬ described embodiment of FIG. 1, so that reference is made to the preceding description and at this point only the differences will be explained.

In the exemplary embodiment illustrated in FIG. 2, the preparation device 4 has a plurality of preparation fibers associated with the individual spinnerets 8.1 to 8.6. Each of the spinnerets 8.1 to 8.6 are assigned two spaced-apart preparation yarn guides 11.1 and 11.2, so that by one of the spinnerets 8.1 to 8.6 extradierte filament system is guided to two parallel running the threads. Thus, the first group of threads 35.1 is formed by a total of 6 threads which are formed from the filament bundles 9.1, 9.2 and 9.3 of the spinning nozzles 8.1, 8.2 and 8.3. The second group of filaments 35.2 is also formed by six filaments formed from the filament bundles 9.4, 9.5 and 9.6 of the spinnerets 8.4, 8.5 and 8.6.

The two groups of threads 35.1 and 35.2 are subtracted by the take-off members 5.1 and 5.2. In this case, the groups of threads 35.1 and 35.2 are guided by a respective thread deflection rod 16.1 and 16.2 as well as a yarn thread guide 17.1 and 17.2 out of the spinning plane into a treatment plane which is oriented orthogonally to the spinning plane. In this case, the threads of the two groups 35.1 and 35.2 are each brought together to form a partial thread set, with a guide spacing between the individual threads. The godets 13.1 and 13.2 of the take-off members 5.1 and 5.2 and the draw godet 19 of the treatment member 6 are arranged side by side in a thread running plane, wherein the axial Aus¬ direction of the godets 13.1, 13.2 and 19 is parallel to the treatment level. Dar¬ results in an advantageous threadline, which leads to a particularly compact design of the device according to the invention. The godets 13.1 and 13.2 are preceded in each case by a predelivery device 18.1 and 18.2 in the treatment level.

For further explanation of the yarn path and the thread treatment can be taken at this point to the aforementioned embodiment of FIG. 1 reference.

The embodiments according to FIGS. 1 and 2 are particularly suitable for producing textile POY threads. However, the device according to the invention and the method according to the invention are not limited to the production of specific types of yarn. Thus, the device according to the invention and the method according to the invention can be achieved by any configuration of the take-off elements and treatment. lungsorgane for the production of all common textile threads (POY ₅ FDY, HOY) technical threads and BCF threads use. By using a plurality of take-off members for simultaneous removal of a plurality of groups of threads from a spinning device, it is possible to achieve particularly low overall heights of the spinning system. The number of juxtaposed spinnerets in the embodiments shown is exemplary, and could also be formed by eight, ten, twelve, or more spinnerets.

In Fig. 3 is shown as a further embodiment of a device which can be used for the production of fully drawn threads. In order to avoid repetition, only the differences from the aforementioned exemplary embodiments are explained in the following descriptions.

The spinning device 1 has at a spinning beam 7 a total of eight juxtaposed spinnerets 8.1 to 8.8. Each of the spinnerets 8.1 to 8.8 ent holds on its underside a circular array of nozzle bores through which a plurality of filaments are extrudable. Below the spinning device 1, a cooling device 2 with a cooling shaft 34 and egg ner cross-flow blowing, not shown here is arranged. In this case, a directed from the outside across the filament coulters cooling medium flow is generated to cool the filaments.

The preparation device 4 provided underneath the cooling device 2 contains for each of the spinnerets 8.1 to 8.8 in each case one preparation yarn guide 11.1 to 11.8 in order to feed the filament bundles 9.1 to 9.8 into a thread in each case.

Below the preparation device 4, two take-off members 5.1 and 5.2 are arranged, which are each provided with a driven godet 13.1 and 13.2 and with one of the godets 13.1 and 13.2 associated freely rotatable overflow rollers 29.1 and 29.2. The godets 13.1 and 13.2 are each a collection thread guide 17.1 and 17.2 as well as a predelivery device 18.1 and 18.2 upstream. By the Sammelfadenfuhrer 17.1 and 17.2 the threads are divided into two groups 35.1 and 35.2 and deducted via the associated trigger members 5.1 and 5.2 from the spinning device 1. The arrangement of the Sammelfadenfuhrer 17.1 and 17.2 is symmetrical to the associated spinnerets 8.1 to 8.4 and 8.5 to 8.8. For a uniform deflection of the particular outer Fä¬ is achieved. To pull off the threads of the two groups 35.1 and 35.2, the godet drives 14.1 and 14.2 are actuated by a group converter 15 having an identical frequency, so that both godets 13.1 and 13.2 rotate at identical peripheral speeds. The godets 13.1 and 13.2 and the associated overflow rollers 29.1 and 29.2 are repeatedly looped around by the threads.

On the discharge side of the take-off members 5.1 and 5.2, a drain thread guide 32.1 and 32.2 are respectively assigned in order to maintain a guide distance between the threads set during removal. Of the running Faden¬ leaders 22.1 and 22.2, the threads of the two groups 35.1 and 35.2 are merged into a yarn sheet 36. For this purpose, the yarn sheet 36 is guided over the seed thread guide 33, which is connected upstream of a treatment member 6. In this case, the treatment member 6 is formed by a drafting field, each having two stretch-rate ducts 31.1 and 31.2. Each of the stretching godet ducts 31.1 and 31.2 is driven in each case via a drive unit 37.1 and 37.2 each consisting of an electric motor with converter. The drive units 37.1 and 37.2 are connected to a control unit 30, which is also connected to the group converter 15 of the take-off members 5.1 and 5.2. In the treatment member 6, the threads are guided and stretched parallel to one another via the stretch godet ducts 31.1 and 31.2. For this purpose, a speed difference is set between the stretch godet ducts 31.1 and 31.2. The stretching godet ducts 31.1 and 31.2 are each formed on two godets, which are arranged in a plane perpendicular to the plane of the drawing. Therefore, only one of the godets is shown in FIG. After stretching, the threads of the yarn sheet 36 are withdrawn by the winding device 3 and wound into coils 27. For thread guidance, a flow-thread guide 22 is here associated with the last draw-godet duo 31.2, by means of which the threads within the treatment member 6 receive a predefined treatment distance from each other. Subsequently, the threads of the yarn sheet 36 are spread and fed to the winding device via the individual yarn thread guides 23. The winding device 3 is designed identically to the preceding exemplary embodiments, so that a total of 8 threads are wound simultaneously to form coils 27 on a long winding spindle 26.1.

The embodiment of the device according to the invention shown in FIG. 3 for carrying out the method according to the invention is based on the fact that the threads are guided in a thread plane between the spinning and the winding. The spinning plane and the treatment plane lie parallel to one another, so that the winding device 3 is aligned parallel to the spinning nozzle row of the spinning device 1. This embodiment is particularly suitable for the production of FDY threads.
