Description

The invention relates to a device for producing a plurality of synthetic threads optionally as monofilaments or composite threads according to the preamble of claim 1.

A generic device is from the DE 10 2009 038 496 A1 known.

The synthetic filaments needed for the textile industry are made, depending on their use, with different devices for melt spinning multifilament yarns. Thus, it is customary in the production of so-called POY yarns (Pre Oriented Yarn) to pull off a yarn sheet after melt spinning through two godets and then to wind it up into coils. The POY yarns are a precursor to a texturing process, which is then preferably carried out with texturing machines.

The synthetic threads, which are suitable for further processing into a flat structure after a melt spinning process, are referred to as so-called FDY threads (Full DrawnYarn). Such threads are stretched after melt spinning at least in a stretching device with multiple godets. In that regard, the devices used for this purpose have a plurality of godets, which pull off, stretch and relax the threads.

Another yarn type required in the textile industry is the so-called effect yarns. Such effect yarns are formed by combining a plurality of yarns having different physical properties. Thus certain yarn effects, such as structural effects, gloss effects or color effects can be generated directly in the melt spinning process, so that these composite threads can be processed directly into textile fabrics. However, the effect yarns are subject to the fashion influences, so that their demand and use is subject to very strong fluctuations.

The known device for producing a plurality of synthetic threads now offers the possibility of optionally producing POY threads, FDY threads or fancy yarns. The POY yarns and FDY yarns are referred to herein as monofilaments, since each of them is formed from a plurality of filaments, all of which have identical physical properties. In contrast, the fancy yarns are referred to herein as composite yarns, since they are formed from at least two different filament bundles in their physical properties.

In order to produce either monofilaments or composite threads, several spinneret groups are used in the known device, which are independently connected to a respective melting source. Each of the spinneret groups is associated with one of two thread-collecting devices which cooperate with godet systems arranged therewith. The godet systems are associated with two separate winding machines with two groups of winding stations. In order to produce either monofilaments or composite threads, conversion measures are required in the known device. Thus, in the production of composite yarns one of the winding machines is implemented such that the yarn sheet of Composite threads can be picked up by a godet system and wound into coils. In addition, a conversion of the godet systems is required in order to produce either monofilaments with a POY property or an FDY property can.

In principle, devices for the production of synthetic threads are known in the prior art, in which the threads are produced from a plurality of spinneret groups. So goes out of the WO 2005 05 22 26 A1 a device in which only monofilaments are produced in large numbers by two spinneret groups. The spinneret groups are associated with a thread-collecting device and a godet system for the production of monofilaments with a POY property. However, this device is completely unsuitable for producing either monofilaments or composite threads.

It is an object of the invention to provide an apparatus for producing a plurality of synthetic threads optionally as monofilaments or composite threads of the generic type, in which no conversion measures of the facilities are required.

Another object of the invention is to provide a device for producing a plurality of synthetic threads, in which a high-flexibility production of monofilaments and composite threads is possible according to need.

This object is achieved in that a common yarn collecting device is arranged in a yarn path between the spinneret groups and the godets, that the yarn collecting device a first Abzugsgalette the godets to form a first vertical Thread running plane and one of the Abzugsgalette the yarn course downstream Führungsgalette or guide roller is assigned to form a further thread running plane.

Advantageous developments of the invention are defined by the features and feature combinations of the respective subclaims.

The invention has the particular advantage that only a thread-collecting device and a godet system is arranged between the spinning device and the take-up device, in order to produce either mono-threads or composite threads with the desired physical properties. The device according to the invention can be produced without conversion measures for producing a plurality of monofilaments having a POY property, monofilaments having an FDY property or composite threads having special effects. By assigning a first withdrawal godet and a downstream Führungsgalette to the yarn collecting device can be used depending on the thread type one of the thread running planes to guide the threads. Thus, depending on the treatment sequence on the godets, the yarn sheets can be introduced into the godet system immediately after the yarn collection device or can only be transferred by a downstream guide godet into a partial area of the godet system. To produce composite threads, the threads are fed to the godet system via both thread running planes. By the godet upstream of the godet gathering a point is also defined, in which all yarn sheets are collectively detected.

In order to avoid the greatest possible deflections when removing and transferring the threads from the spinning device, the device according to the invention is preferably designed such that the withdrawal godet and the downstream Führungsgalette or guide roller is arranged relative to the yarn collecting device, that the clamped yarn running planes between them form an angle in the range of 0 ° - 15 °.

The thread guide of the threads can be advantageously ensured by the configuration of the thread collecting device, which has at least one Kammfadenführer for guiding the threads and a thread cutting device with a Fadenabsaugung. The combed yarn guide allows a guide of a plurality of threads with a predetermined distance between the threads. Thus, the threads can be guided parallel to each other at a small distance in the range of 4 mm to 10 mm together over the godets.

The godets are preferably arranged according to an embodiment of the invention to a yarn path with simple wrap, with more of the Abzugsgalette downstream thread guide godets are held for stretching and guiding the threads laterally next to the thread running planes. This ensures that, depending on the inlet height of the threads, which are defined by the withdrawal godet or the guide godet, the treatment of the threads is carried out differently.

In order to improve the cohesion of the filaments in the monofilaments or the composite threads, the development of the invention is provided in which a swirling device is arranged between two Führungsgaletten having a plurality of treatment channels for selectively swirling monofilaments or composite threads. Such turbulators are preferably held at the end of a godet system to produce the thread closure on the monofilaments or the composite yarns prior to winding.

The extrusion of the threads can be carried out in any manner through a plurality of spinneret groups. The spinneret groups can in this case be formed by a plurality of multiple spinnerets, each with a plurality of melt inlets, which are held in rows on a spinning beam. Such multiple spinnerets have the particular advantage that the threads can be produced side by side in close pitch.

Alternatively, however, it is also possible to arrange the spinnerets of the spinneret groups distributed over several spinnerets, which are held side by side.

In order to be able to wind all monofilaments or all composite threads at the end of the process as required, it is further provided that the winding point groups are distributed on at least two separate winding machines, which face each other mirror-symmetrically and are independently controllable. Thus, for example, the composite threads can preferably be wound up with only one of the winding machines. In the production of monofilaments, however, preferably both winding machines are used to operate the winding head groups.

An extremely compact arrangement of the device can be achieved by the development of the invention, in which the godets are held on a support frame above the winding machine such that the threads in the winding point groups of a front end region of the winding machine can be fed. This eliminates the spreading of the yarn sheet of a treatment distance to a winding distance. The yarn sheet can be advantageous to perform over several pulleys the winding points.

It has been found that the treatment of the monofilaments with FDY characteristic is preferably carried out on non-prepared threads. This allows additional heat energy, which is usually required for heating wetted threads, save. For this case, the development of the invention is particularly preferred in which the thread collecting device is assigned a first preparation station for preparing the threads and in which between the Führungsgaletten a second preparation station for preparing the threads is provided and in which the preparation station are independently controllable. This makes it possible to prepare the threads immediately after the extrusion and before stretching or after stretching or in the two preparation stations. This ensures a high degree of flexibility for producing the threads.

The invention will be explained in more detail below with reference to some embodiments of the device according to the invention with reference to the accompanying figures.

In the FIGS. 1 and 2 a first embodiment of the device according to the invention for producing a plurality of synthetic threads is shown schematically in several views. In FIG. 1 the device is in a cross-sectional view and in FIG. 2 shown in a longitudinal sectional view. In so far as no explicit reference is made to one of the figures, the following description applies to both figures.

The in the FIGS. 1 and 2 The device shown has two groups of spinnerets 2 and 3. The spinneret group 2 and the spinneret group 3 each comprise a total of four separate spinnerets in a row-like arrangement. As in particular from the illustration in FIG. 2 As can be seen, the two spinneret groups 2 and 3 and their spinnerets are formed by multiple spinnerets 4.1 to 4.4. Each of the multiple spinning nozzles 4.1 to 4.4 thus contains in each case a spinneret 2.1 of the spinneret group 2 and a spinneret 3.1 of the spinneret group 3. Such multiple spinnerets 4.1 to 4.4 are distinguished by the fact that two spinnerets are integrated in a nozzle package, which are fed via separate melt inlets.

The multiple spinning nozzles 4.1 to 4.4 with the spinneret groups 2 and 3 are arranged in a spinning beam 1. The spinning beam 1 is designed to be heatable, wherein the spinning beam 1 is preferably connected via an inlet and a drain to a heat transfer circuit. At the top of the spinning beam 1, a driven spinning pump 5 is arranged, which is designed as a multiple pump and is connected via a plurality of distribution lines 7 with the spinnerets 2.1 to 2.4 and 3.1 to 3.4. The spinning pump 5 is connected via a melt inlet 6 with a melt source, e.g. connected to an extruder.

Below the spinner 1 a cooling device 8 is arranged. The cooling device 8 is designed in this embodiment as a so-called Querstromanblasung. For this purpose, a blow chamber 11 with a blown wall 10 facing the extruded filaments is formed laterally of the spinneret groups 2 and 3 below the spinneret. The blow chamber 11 is connected to a source of cooling air and generates via the blowing wall 10 a flowing into a cooling duct 9 cooling air flow. The cooling shaft 9 extends below the spinneret groups 2 and 3.

Below the cooling shaft 9, each spinneret of the spinneret groups 2 and 3 is assigned a thread guide 12 in each case in order to carry out bundling of the extruded filaments per thread.

The yarn guides 12 is associated with a yarn collection device 16 in the yarn path, through which the extruded through the spinnerets threads are brought to a treatment distance from each other. In that regard, takes place between the yarn guides 12 below the cooling shaft 9 and the yarn collection device 16, a deflection of the threads instead. This deflection of the threads allows a common treatment of the threads ever as required, as one thread group or as two separate thread groups with relatively narrow thread pitch between the threads.

In this embodiment, the thread collecting device 16 is formed by a Kammfadenführer 17, each having separate guide grooves for each thread. The combed yarn guide 17 is coupled to a linear drive 18, so that the combed yarn guide 17 can be guided between an operating position and an articulation position. In the deflection position, the comb thread guide 17 cooperates with a thread cutting device 19 and a thread suction device 20. Thus, for example, the entire yarn sheet of the two thread groups can be severed together at a yarn breakage by the thread cutting device 19 and lead over the thread suction 20 to a waste container.

The thread-collecting device 16 is downstream of a godet 21 in the yarn path.

To explain the godet system 21 is in addition to the Figure 3.1 Referred to in the FIG. 1 shown enlarged galette system represents. In that regard, the following description applies to the FIGS. 1 to 3.1 ,

The godet system 21 has, in the direction of yarn travel, a first withdrawal godet 22 which, with the yarn collection device 16, tensions a vertical first yarn path plane 23.1. The withdrawal godet 22 is followed by a plurality of guide godets 24.1, 24.2, 24.3 and 24.4 arranged one below the other. The guide godets 24.1 to 24.4 form a draw zone in the godet system 21, wherein a guide roller 25 is arranged between the guide godets 24.2 and 24.3. The guide godets 24.1 to 24.4 and the guide roller 25 are arranged to form an S-shaped yarn path, so that the yarn sheet on the circumference of the guide godets 24.1 to 24.4 can be guided with simple looping.

In the lower part of the godet system 21, two further guide godets 24.5 and 24.6 are arranged for further yarn guidance. The Abtraggalette 22 downstream Führungsgalette 24.5 is arranged on the godet system 21 such that adjusts a second yarn running plane 23.2 between the yarn collection device 16 and the guide godet 24.5. The second threadline 23.2 is in the FIGS. 1 and Figure 3.1 shown in dashed lines. In the godet system 21, the take-off godet 22 and the downstream guide godet 24.5 are arranged relative to the yarn collecting device 16 such that an angle extends between the yarn running planes 23.1 and 23.2. In Figure 3.1 the angle is shown with the label α.

The thread running planes spanned between the thread collecting device 16 and the withdrawal godet 22 and the guide godet 24.5 are suitable for separating the yarn sheet of both spinneret groups 2 and 3 and for removing them separately. Alternatively, however, it is also possible to guide all the threads of the spinneret groups 2 and 3 together in the thread running plane 23.1 via the take-off godet 22 or together through the thread running plane 23.2 via the guide godet 24.5. In order to obtain the trigger no unwanted deflections on the threads, the arrangement of Abzugsgalette 22 and the Führungsgalette 24.5 relative to the thread collecting device 16 is selected such that extending between the thread running planes 23.1 and 23.2 angle α in the range of 0 ° to 15 ° lies. In that regard, all prepared by the godets 22 and 24.5 Means for the treatment of the threads are used independently of the leadership of the threads in the godet 21.

As in particular from the representations in FIG. 1 and 3.1 As can be seen, a preparation station 13.2 is arranged between the guide godets 24.4 and 24.5. The preparation station 13.2 has a wetting agent 14.2 and a dosing 15.2 to perform wetting in the preparation station 13.2 optionally on the guided between the godets 24.4 and 24.5 threads wetting.

As from the illustrations in FIG. 1 and FIG. 2 shows, the preparation station 13.2 cooperates with a second preparation station 13.1. The preparation station 13.1 is assigned directly to the yarn guides 12 below the cooling shaft 9 in order to wet the freshly extruded filaments after cooling. The preparation station 13.1 likewise has a wetting agent 14.1 and a dosing agent 15.1. The preparation station 13.1 is also designed controllable, so that optionally the threads are wettable after cooling.

As from the representations in the FIGS. 1 . 2 and 3.1 shows, is a last Führungsgalette 24.6 vortexing device 26 upstream. The swirling device 26 has a plurality of treatment channels 27, in each of which a compressed air for swirling the threads can be fed. Such turbulators 26 are well known and will therefore not be further explained at this point. The treatment channels 27 of the swirling devices 26 are designed in such a way that either individual threads or a plurality of threads can be guided therein. Thus, the turbulators 26 can be advantageous to create multiple monofilaments or multiple composite threads.

As from the illustrations in FIG. 1 and FIG. 2 shows, the godets of the godet 21 are arranged on a support plate 29 which is supported on a support frame 28. The support plate 29 is particularly suitable for holding the guide shells 44 of the godets on a front side and the godet drives 45 on a rear side. The usually executed encapsulations of the guide sheaths 44, which are heated and unheated executable, and the encapsulations of the godet drives 45 are not shown here.

Below the godet system 21 two winding machines 30.1 and 30.2 are arranged mirror-symmetrically to one another. The winding machines 30.1 and 30.2 are framed by the support frame 28, wherein the support plate 29 is arranged with the godet system 21 at a front end face of the winding machines 30.1 and 30.2.

The winding machines 30.1 and 30.2 are identically constructed and each contain a winding point group 31 and 32. So is in FIG. 1 the winding point group 31 of the winding machine 30.1 shown. The winding station group comprises a total of four winding points 31.1 to 31.4. The winding stations 31.1 to 31.4 are formed along a winding spindle 33.1. The winding stations 31.1 to 31.4 each have a traversing device 35 and a deflection roller 36 in order to wind the yarns supplied via the deflection roller 36. The threads are deposited in the winding stations 31.1 to 31.4 by a pressure roller 34 on the surfaces of the coils 38. The winding stations 31.1 to 31.4 is associated with a second winding spindle 33.2, wherein both winding spindles 33.1 and 33.2 are held on a winding turret 37. Thus, a continuous winding of the threads in the winding points 31.1 to 31.4 can be realized.

The winding machine 30.2 is formed identically with a second winding point group 32, wherein here also four winding points 32.1 to 32.4 are provided.

It should be noted here that the number of spinnerets and the number of spools per group are exemplary. In principle, more than four threads can be spun as a thread group, stretched and wound up.

This in FIG. 1 and 2 illustrated embodiment of the device according to the invention is shown in an operating situation in which a plurality of monofilaments are produced with an FDY characteristic. For this purpose, the yarns spun by the two spinneret groups 2 and 3 are withdrawn together as a group of yarns through the draw-off godet 22. On the way to the withdrawal godet 22, the bundling is carried out by the yarn guides 12 and the merger through the yarn collecting device 16. The preparation station 13.1 is deactivated, so that the threads are removed in a dry state from the spinnerets of the spinneret groups 2 and 3. The threads, which are identified by the reference numeral 46, are guided in an S-shaped yarn path through the godet system 21, wherein at least the guide godets 24.1 to 24.4 have a heated guide shell. In particular, the guide godets 24.2 and 24.3 are driven at a greater differential speed for drawing the threads.

After stretching, the threads are wetted in the second preparation station 13.2 and then guided via the guide godets 24.5 and 24.6 to the winding point groups 31 and 32. Previously, the threads are individually treated in the swirling device 26, so that in each case a monofilament with FDY properties can be produced from each of the threads extruded through the spinneret groups 2 and 3.

Since the production of composite threads or monofilaments is essentially determined by the treatment of the threads in the godet system, will be described below with reference to the Figures 3.2 and 3.3 the alternative mode of operation of the device according to the invention FIG. 1 and 2 described.

In Figure 3.2 the thread running situation is shown on the godet system 21 when producing a composite thread. In this exemplary embodiment, a first thread group 47.1 is introduced into the godet system 21 via the take-off godet 22 in the first thread running plane 23.1. Thread group 47.1 is stretched in the following guide godets. In contrast, a second thread group 47.2 is introduced in the second thread running plane 23.2 directly from the thread collecting device 16 via the guide godet 24.5 in the godet 21. The threads of the thread group 47.2 thus receive a POY characteristic. At the guide godet 24.5, the second thread group 47.2 is guided together with the already drawn thread group 47.1 in such a way that in each case a thread with an FDY characteristic and a thread with the POY character trait are guided together through a treatment channel 27 of the swirling device 26. The two monofilaments can be combined so advantageous to a composite thread. Thus, the threads of the thread groups 47.1 and 47.2 can be added merge a group of multiple composite threads. The composite threads are then wound into coils in the winding positions of one of the winding setting groups 31 or 32. This is how the in FIG. 1 and 2 used apparatus shown alternative for producing a plurality of composite threads. In this case, the threads of the thread group 47.1 are preferably wetted by the preparation station 13.2 and the threads of the thread group 47.2 preferably by the preparation station 13.1.

The in the FIG. 1 and 2 However, the device shown can also be used alternatively without modifications for the production of monofilaments with a POY characteristic. The thereby adjusting threadline in the godet 21 is shown in FIG Figure 3.3 shown. Here, the threads 46, which are extruded through the spinnerets of the spinneret groups 2 and 3, are guided together in the second thread running plane 23.2 and withdrawn through the guide godet 24.5. After the turbulence of the threads in the swirling device 26, these are guided via the last guide godet 24.6 to the winding points of the winding positioning groups 31 and 32. The last guide godet 24.6 is held in the lower region of the godet system 21 preferably laterally to the winding positions of the winding positioning groups 31 and 32, so that the threads can be distributed substantially from a horizontal distribution plane out on the winding points. The in the FIGS. 1 and 2 illustrated inventive device is designed to be particularly compact and easy to use.

The in the FIGS. 1 and 2 Melt-spinning, stripping and drawing devices as well as the winding of the threads shown are examples. It is essential here that the device for melt spinning has a common thread collection device and a godet system with a godet arrangement which, with the thread collection device, has two thread running planes forms for optional entry into various godet arrangements for the treatment of the threads, are assigned. The godets of the godet system 21 are therefore preferably equipped with individual drives to adjust depending on the application and process certain peripheral speeds can. The guide godets can also be replaced by driven guide rollers, so it is also possible to form the second thread running plane between the thread-collecting device and a driven guide roller.

For melt-spinning the threads, alternatively, an arrangement of the spinning device can be selected, as for example in FIG. 4 is shown. In this example, the spinneret groups 3 and 4 are formed by separate spinnerets 2.1 and 3.1, which are held side by side on a spinning beam 1. Below the spinnerets 3.1 and 2.1, which form on the underside of the spinner 1 in rows to several side by side or offset to each other spinneret groups 2 and 3, a cooling shaft 9 is formed, on both sides in each case a blast wall 10.1 and 10.2, each with a blast chamber 11.1 and 11.2.

Below the cooling shaft 9, the spinnerets 2.1 and 3.1 thread guide 12 and wetting agents 14.1 and 14.2 of the first preparation station 13.1 assigned. The wetting agents 14.1 are assigned to the spinnerets of group 2 and the wetting agents 14.2 to the spinnerets of group 3. The wetting agents 14.1 and 14.2 are connected to separate dosing means 15.1 and 15.2, so that the first preparation station 13.1 can be used selectively to wet a group of threads or both sets of threads.

However, there are also spinning devices possible, as for example in the Figure 5.1 and Figure 5.2 are shown. The Figure 5.1 shows the cross-sectional view and the Figure 5.2 a cross-sectional view of a spinning device, as for example, alternatively in the in FIG. 1 and 2 illustrated device would be used. In this exemplary embodiment, two spinning beams 1.1 and 1.2 are arranged parallel next to one another, each of the spinning beams 1.1 and 1.2 each holding a plurality of spinning nozzles of a spinning nozzle group 2 and 3. Thus, in this embodiment, the spinneret groups 2 are also shown by four spinnerets 2.1, 2.2, 2.3 and 2.4. The arranged below the spinning beam 1.1 and 1.2 cooling device 8 has in this embodiment, each spinneret 2.1 to 2.4 and 3.1 to 3.4 each have a screen cylinder 39 which is disposed in an upper pressure chamber 40. The screen cylinder 39 penetrate the pressure chamber 40 to a bottom, at which a pipe socket 43 each followed the screen cylinders 39. The pipe sockets 43 are embedded in a distribution chamber 41, which is coupled on the one hand via a cooling air connection 42 with a cooling air source and on the other hand has a connection to the pressure chamber 40. In that regard, to cool the extruded filaments, a radially from outside to inside flowing cooling air flow is generated.

The in the Figures 5.1 and 5.2 illustrated cooling device 8 is selected according to the desired yarn type, so that the cooling devices shown in the embodiments are interchangeable.

According to the embodiment Figure 5.1 and Figure 5.2 the yarn guides 18 and the wetting agent 14.1 of the preparation station 13.1 are combined to perform a bundling of the threads. Basically you can However, all variants shown for bundling in the embodiments shown are used alternatively.
