Description

Device for stripping and stretching multifilament threads

The invention relates to a device for stripping and stretching multifilament yarns in a melt spinning process according to the preamble of claim 1.

In the production of multifilament yarns in a melt-spinning process, it is known to remove the freshly spun multifilament yarns from the spinning device and, depending on the type of yarn, to carry out a more or less high degree of stretching and any further treatments in order to form the multifilament yarn at the end of the treatment Coil can be wound up. For pulling off and stretching the multifilament threads usually godets are used, which have a driven guide shell, on the circumference of the threads are guided with a Teilumschlingung. Depending on the desired stretching or stretching forces required for drawing, the guide shells of the godets are simply or repeatedly looped around by the thread. In this case, in particular the drawing operation in the multifilament threads is assisted by a temperature control of the threads. In order to heat the multifilament yarns before stretching, systems are generally known in which the heating of the yarns takes place by means of separate heating means or directly by heated guide shells of the godets.

For example, US Pat. No. 5,137,670 discloses a generic device in which a heating means is arranged in the yarn path between two godets. The heating means is designed as a heated plate, is guided at the surface at a small distance from the thread. Here, the thread is tempered by heat exchange in the form of heat convection and heat conduction. For this purpose, the hot plate is heated to a temperature in the range of 250 ⁰ C to 500 ⁰ C. Such systems have the disadvantage that the distance between the thread and the heated plate significantly influences the heat exchange. Thus, the filaments in the yarn composite depending on the location, whether they are facing the heating plate or whether they are located on the opposite side of the thread, uneven tempered.

In order to improve such unevenness in the temperature control of multifilament yarns, systems are known in which the multifilament yarn is tempered with contact on a heated surface. For example, US Pat. No. 5,902,503 discloses a godet in which the guide casing is heated by internal infrared radiation elements. In this case, the energy of the infrared radiation elements is supplied to the guide casing of the godet by electromagnetic waves and heated. To control the temperature of the thread this is performed with several wraps on the circumference of the guide shell, wherein the thread composite formed by a plurality of filaments is spread. In such systems, however, care must be taken to ensure that the surface temperature of the heated surface as possible has the target temperature of the tempered thread in order to avoid material damage. Thus, at high yarn speeds greater heating distances are required to heat the thread. Such heating sections can therefore be realized only by a plurality of wraps with correspondingly long protruding godets.

It is an object of the invention to provide an apparatus for stripping and stretching multifilament yarns of the generic type in which the multifilament yarns can be intensively heated without contact.

Another object of the invention is to provide a generic apparatus for stripping and stretching multifilament yarns in which a plurality of yarns is heated as evenly as possible without contact. This object is achieved in that the heating means are formed by a plurality of juxtaposed elongated heat radiation body, which extend substantially parallel to the guide shells of the godets and which are arranged in the bounded by the taut pieces of thread clearance between the guide shells of godets.

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

The invention is characterized in that a high radiation density of heat rays for heating the filaments can be generated. Thus, the entire gap between the guide shells of the godets can be advantageously used to place several heat radiation body side by side in a confined space. The high integration of heat between the godets leads to a very compact design.

The development of the invention, in which the heat radiation body are formed by infrared radiation body, is characterized by the fact that the energy transport between the heating means and the multifilament yarns takes place exclusively by an electromagnetic wave radiation. This energy transport is independent of the distance and the environment of the multifilament yarn to the heating medium out. In order to obtain a high radiation density in the yarn path between the godets for the heating of the multifilament threads, the infrared radiation bodies are arranged side by side, wherein the infrared radiation body extending parallel to the guide shells of the godets and in the bounded by the taut pieces of thread clearance between the guide shells of the godets are arranged. Thus, the entire interspace between the guide shells of the godets can advantageously be used to generate a high radiation density of infrared rays with a plurality of infrared radiation bodies and thus to heat the group of yarns. Purely physical terms, which generates from US 5,137,670 known heating means in the form of a hot plate with a surface temperature to 500 ⁰ C also to control the temperature of a heat radiation, which, however, are not suitable due to their wavelength multifϊle threads made of a polymeric material. It is known that the absorption for the infrared radiation is greatest for polymer materials in the wavelength range of 2.5 μm to 4 μm. However, such a wave spectrum can be generated without problems by infrared radiation bodies.

In order to be able to realize yarn speeds in the range of above 3,000 m / min in the production of drawn multifilament yarns, according to an advantageous development of the invention, a heating path running through the yarns by the infrared radiation bodies forms a length of at least 500 mm having. Basically, the number and choice of the infrared radiation body can also realize greater lengths in the range of> 800 mm.

In an advantageous development of the invention, in which the infrared radiation bodies can be operated within the heating zone with the same or different jet power, temperature profiles within the heating zone can advantageously be realized. Thus, for example, with different beam powers simple looping of the godets the inlet of the heating section for a higher temperature control of the thread set, which is then reduced by a reduced beam power to the end of the heating section out.

The infrared radiation bodies are preferably formed by heating tubes which are connected to one another to form a heating module and generate heat radiation on two sides, wherein the heating module is arranged in a center plane spanned by the axes of the godets. With multiple wrapping of the guide sheaths, it is thus possible to tie the sheaths between the guide sheaths.

- A - Heat ten pieces of thread on both an upper side and on a bottom through the heating tubes.

Due to low heat-up times and fast switching options, the heating tubes are preferably equipped with a Carbonheizleiter to generate the infrared radiation in the wavelength range of 2 microns to 4 microns. Here, the carbon heater can be heated to a temperature of above 1000 ⁰ C in a few seconds.

In order to be able to guide the multifilament yarns with multiple wrapping in order to be able to produce, for example, higher pull-off forces or stretching forces, it is proposed according to an advantageous development of the invention to drive the guide casing of one of the godets by an electric motor, wherein the guide casing of the associated godet is freely rotatably mounted and opposite the guide shell of the driven godet has a tendency to thread laying.

In this case, the guide casing of the free-running godet in comparison to the guide casing of the driven godet have a smaller or equal diameter.

In principle, however, it is also possible to drive the guide shells of both godets by separate electric motors. Depending on the intended use, the guide sheaths can be operated by the electric motors at the same circumferential speeds or with a speed difference generated between the guide sheaths.

In order to obtain a compact arrangement of the godets and the heating means, in particular, the development of the invention has proved successful, in which rather a godet carrier is provided for holding both godets, which also carries the arranged between the godets heating means. For this purpose, the godet carrier is preferably formed by two longitudinal carriers arranged at a distance from one another, on which the guide shells of both godets are rotatably mounted towards both end faces and which are combined with the heating means to form a godet module. Such godet modules represent an assembly that can be used flexibly in a melt spinning process.

Due to the compact arrangement, such godet modules can preferably be integrated with horizontally aligned arrangement of the godets and the heating means in an upper platform of a winding machine. Thus, compact arrangements in a melt spinning process can be realized, which allows the operability of the winding machine and the godet module from an operating level out.

For stretching the multifilament yarns preferably multiple godets are used, so that a development of the invention provides that the two godets are associated with several other godets, which have between them another heating means. The heating means is also formed by a plurality of juxtaposed infrared radiation body, which extend substantially parallel to the guide shells of the godets and which are arranged in the bounded by the taut pieces of thread space between the guide shells of the godets. In this way, in particular, tempering can also be carried out for so-called relaxation or shrinkage treatment of the threads.

In the case of a plurality of godets and heating means, these are preferably combined as separate godet modules and arranged one above the other in a drawing field.

In order to avoid unwanted environmental influences, such as a climatised air in the hall, when the heating of the threads is possible, the godets and the heating means are preferably located in a heating chamber. assigns. The threads are then fed to and removed from the godets through thread inlets and thread outlets of the heating chamber.

Depending on the melt spinning process and yarn type, the device according to the invention is both suitable for producing so-called preoriented POY yarns or fully drawn FDY yarns. The invention will be explained in more detail below with reference to the attached figures with reference to some embodiments of the device according to the invention.

In Fig. 1 and Fig. 2, a first embodiment of the device according to the invention is shown in several views. In Fig. 1, the device is shown in a cross-sectional view and in Fig. 2 in a plan view. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The embodiment has two galette duo with the godets 1.1 and 1.2 and the underlying godets 1.3 and 1.4. The godet 1.1 has a guide shell 2.1, the projecting rotatable about a godet axis 11.1 is mounted on a godet carrier 4.1. the godet axis 11.1 is rotatably coupled to the guide casing 2.1 and is driven by a godet 14.1.

At a distance from the godet 1.1, the second godet 1.2 is arranged on the godet carrier 4.1. The godet 1.2 has a guide casing 2.2, which is rotatably coupled to the godet axis 11.2. The godet axis 11.2 is freely rotatably mounted with a projecting end in the godet carrier 4.1. The guide casing 2.2 of the godet 1.2 is also provided with a slightly inclined guide casing 2.1 of the godet 1.1 (see Fig. 1), around a guide sheath 2.1 supplied yarn sheet 3 of several synthetic multifϊlen threads in several wraps around the guide shells 2.1 and 2.2.

In the space between the guide shells 2.1 and 2.2, a heating means 5.1 is arranged. The heating means 5.1 is formed by a plurality of infrared radiation bodies 6.1, 6.2, 6.3, 6.4 and 6.5. The infrared radiation body 6.1 to 6.5 are held in a median plane between the guide shells 2.1 and 2.2, which is spanned by the godet axes 11.1 and 11.2.

The infrared radiation bodies 6.1 to 6.5 are of identical construction, so that the structure of the infrared radiation bodies is explained using the example of the infrared radiation body 6.1. The infrared radiation body 6.1 to 6.5 each have a heating tube 8, in which a carbon heater 9 is arranged. The heating tube 8, which is designed as a double tube, has a free end in the region of the projecting end faces of the guide sheaths 2.1 and 2.2. With the opposite end of the heating tube 8 is held on a connection carrier 28 which is fixed to the godet carrier 4.1. About the connection carrier 28 and a line 29, the electrical connection of the heating tube 8 to an electrical supply and control unit, not shown here takes place. The connection carrier 28 holds all the heating tubes 8 of the infrared radiation body 6.1 to 6.5 and forms a Heating module 7, which is held as a unit replaceable on the godet carrier 4.1.

In the heating module 7, the infrared radiation bodies 6.1 to 6.5 are combined to form a heating track. The heating tubes 8 of the infrared radiation bodies 6.1 to 6.5 emit their infrared rays to an upper side 32 and to a lower side 30. The guide shells 2.1 and 2.2 of the godets 1.1 and 1.2, which extend parallel to the infrared radiation bodies 6.1 to 6.5 at the ends of the heating section, are made larger in diameter than the diameters of the heating tubes 8, so that the guide sheaths 2.1 and 2.2 are guided Threads 3 each with the tensioned between the guide shells 2.1 and 2.2 pieces of thread above or below the infrared radiation body 6.1 to 6.5 are performed. In operation, the yarn pieces of the yarn sheet 3 are thus exposed on the top 32 and on the bottom 30 of the infrared radiation. The electromagnetic wave structure generated by the carbon heating conductors 9 in the heating tubes 8 are particularly matched to the polymer material of the thread, so that as many rays as possible are absorbed in the material of the filaments in order to obtain heating of the threads. For this purpose, the infrared radiation generated by the heating tubes 8 preferably has a spectrum of wavelengths in the range of 2 to 4 μm.

The first galette duo with the godets 1.1 and 1.2 is followed by a second galette duo with the godets 1.3 and 1.4. The godets 1.3 and 1.4 are identical to the godets 1.1 and 1.2 formed, wherein the guide sheaths 2.3 and 2.4 are projectingly supported rotatably on a second godet carrier 4.2. The godet 1.3 is driven by a second godet drive (not shown), wherein the peripheral speed of the guide casing 2.3 with respect to the peripheral speed of the guide casing 2.1 of the godet 1.1 is selected to be larger to obtain a draw of the yarn sheet 3 between the godets 1.1 and 1.3. The held on the godet carrier 4.2 second godet 1.4 is freely rotatably mounted with its guide sheath 2.4. For this purpose, the guide casing 2.4 of the godet roller 1.4 has a slight inclination with respect to the guide casing 2.3, in order to be able to lead a multiple looping of the yarn sheet 3 on the godet duo.

The guide sheaths 2.3 and 2.4 are arranged vertically below the guide sheaths 2.1 and 2.2, wherein the godet carriers 4.1 and 4.2 are arranged offset from one another, so that the yarn sheet 3 running from the guide sheath 2.2 at a protruding end of the guide sheath 2.2 directly onto a bearing end of the Leadership Mantle 2.3 hits.

In the space between the guide sheaths 2.3 and 2.4, a second heating means 5.2 is arranged. The heating means 5.2 is identical in construction to the heating means 5.1, so that no further explanation takes place at this point. The infrared radiation body 6.1 to 6.5 of the second heating means 5.2 form a second heating section between the godets 1.3 and 1.4. The infrared radiation body 6.1 to 6.5 are also attached to this as a heating module 7 via a connection carrier 28 to the godet carrier 4.2.

The second heating means 5.2 is located in a median plane between the guide sheaths 2.3 and 2.4, so that the thread pieces of the yarn sheet 3 are guided on an upper side 30 and a bottom side 29 with uniform spacing and without contact with the infrared radiation bodies 6.1 to 6.3.

In the embodiment of the inventive device shown in Fig. 1 and 2, the yarn sheet 3 is stretched between the godets 1.1 and 1.3. For this purpose, the threads of the yarn sheet 3 are first heated by the first heating means 5.1 to a stretching temperature. After stretching is carried out by the second heating means 5.2 between the godets 1.3 and 1.4, an aftertreatment, for example for shrinkage release. In that regard, the apparatus shown in Figs. 1 and 2 is particularly suitable for producing a fully drawn yarn in a melt spinning process.

The structural arrangement of the godets 1.1 to 1.4 and arranged between the godets heating means 5.1 and 5.2 is exemplary. In principle, the leadership coats of a godet can be designed in different sizes or in the same size. Furthermore, the number of infrared radiation bodies, which are arranged parallel to the guide shells, can be freely selected. This heating tubes can be used, which generate only one side of an infrared radiation. Thus, for example, only the thread pieces on the top or only the thread pieces on the underside between the godets can be tempered. In addition, the length of the heating section is selectable. Depending on the number of infrared radiators, the lengths in the range of 500 mm to 1,000 mm or above are possible.

The heating means 5.1 and the godets 1.1 and 1.2 are preferably arranged in a heating chamber, not shown here. This allows the environment to be shielded so that the climatic conditions usually prevailing in a hall have no influence on the heating of the thread.

FIGS. 3 and 4 show a further exemplary embodiment of the device according to the invention in several views. Fig. 3 shows schematically a side view and in Fig. 4, the device is shown in a plan view. Unless an explicit reference is made to one of the figures, the following description applies to both figures.

The embodiment of FIGS. 3 and 4 is substantially identical to the embodiment of FIGS. 1 and 2, so that only the differences will be explained below and otherwise reference is made to the preceding description. In the embodiment illustrated in FIGS. 3 and 4, two godets 1.1 and 1.2 are combined to form a godet module 16. Each of the godets 1.1 and 1.2 has a rotatable guide casing 2.1 and 2.2. The guide casing 2.1 of the godet 1.1 is rotatably connected to a godet axis 11.1, which is mounted to a front side via a rear bearing 13.1 in a side member 10.1 and with a front bearing 12.1 in a second opposite side member 10.2. The godet axle 11.1 is coupled to the rear bearing 13.1 with an electric motor 14.1 for driving the guide casing 2.1. The guide sleeve 2.2 of the godet 1.2 is held freely rotatably on the longitudinal members 10.1 and 10.2 by the bearings 12.2 and 13.2. The guide casing 2.2 is held with a slight slope in relation to the guide casing 2.1 of the godet 1.1, to lead a group of yarn in multiple wrapping can.

In the space formed by the guide sheaths 2.1 and 2.2 on the one hand and by the side members 10.1 and 10.2 on the other hand, the heating means 5.1 is arranged. The heating means 5.1 is identical to the previous embodiment, so that reference is made to the preceding description. Alternatively, however, the heating module 7 formed by the infrared radiation bodies 6.1 to 6.5 can be connected to each of the longitudinal members 10.1 and 10.2.

The exemplary embodiment of the device according to the invention shown in FIGS. 3 and 4 forms a godet module 16, which can be superimposed as one structural unit, preferably several in a melt spinning process, in order to pull and stretch a plurality of mutli-filament yarns. Likewise, such godet modules can be used for the after-treatment of an already drawn thread. It is essential that the group of threads is heated by infrared radiation without contact between the godets.

Such godet modules, as shown in FIGS. 3 and 4, can preferably be combined with winding machines in order to be as compact and as compact as possible. to obtain user-friendly units for the production of melt-spun threads. Thus, an exemplary embodiment of an installation situation of such godet modules is shown in FIG. The godet modules 16.1 and 16.2, which are identical to the exemplary embodiment according to FIGS. 3 and 4, are arranged directly with a module carrier 31 on an upper platform 18 of a winding machine 17. The winding machine 17 has a machine frame 15, which forms the upper plate 18 and which has the furnishings for a total of four winding units 21.1 to 21.4 to simultaneously wind a four-thread set of threads 3 to coil 26. For this purpose, in each winding unit 21.1 to 21.4 a deflection roller 20, a traversing device 23, a extending over all winding points pressure roller 24 and two alternately guided in a winding area winding spindle 22.1 and 22.2 provided on which the coils 26 are wound simultaneously.

In order to guide the winding spindles 22.1 and 22.2 alternately in the winding area, a spool revolver 25 is provided, which leads by rotation, the winding spindles 22.1 and 22.2 alternately from the winding area in a changing area.

In the transition region between the godet modules 16.1 and 16.2, which stretch the threads of the yarn sheet 3 prior to winding, a flow godet 19 is provided, which is held at a front end of the winding machine 17. Here, the yarn sheet 3 is guided over the Ablaufgalette 19 and distributed to the individual guide rollers 20 of the winding units 21.1 to 21.2.

In the exemplary embodiment shown in FIG. 5, the spinning device can be arranged with a spinning shaft directly above the godet modules 16.1 and 16.2, so that a low overall height of the spinning device is achieved. The godet modules 16.1 and 16.2 are attached to one of the side members 10.1 or 10.2 on the module carrier 31, so that the out of a spinning shaft threads of the yarn sheet 3 in a simple manner by a manually guided suction gun on the godets of the godet modules 16.1 and 16.2 can be applied , The Godet modules 16.1 and 16. 2 are usually in a heating chamber (not shown here), which is held on the module carrier 31. The yarn sheet 3 can then feed through Fadenöffhungen in the heating chamber the godet modules 16.1 and 16.2.

The exemplary embodiment illustrated in FIG. 5 is preferably used for the production of fully drawn threads. In principle, however, it is also possible to use the device according to the invention for the production of pre-oriented threads.

Thus, an embodiment of the inventive device is shown in Fig. 6, in which the yarn sheet is guided with a Teilumschlingung to the godets. The embodiment in Fig. 6 is shown schematically in a side view.

On a godet carrier 4, which is similar to the godet carrier of the embodiment of FIG. 1 and FIG. 2, for example, two godets 1.1 and 1.2 are arranged at a distance from each other. The godet 1.1 has a guide casing 2.1 and the godet 1.2 the guide casing 2.2. Both guide shells 2.1 and 2.2 are driven by electric motors, not shown here. In the space between the guide shells 2.1 and 2.2, a heating means 5 is provided, which is formed in total by four infrared radiation body 6.1 to 6.4. The infrared radiation body 6.1 to 6.4 are aligned parallel to the guide shells 2.1 and 2.2 and held as heating tubes 8 to a connection carrier 28. The heating tubes 8 have a radiation outlet facing an upper side 32, so that the yarn section of the yarn sheet 3 stretched between the guide sheaths 2.1 and 2.2 is heated by the infrared radiation of the infrared radiation bodies 6.1 to 6.4.

In order to obtain the necessary looping of the yarn sheet 3 on the godets 1.1 and 1.2 for stripping and drawing, are the leaders covers 2.1 and 2.2 each associated with a deflection roller 27.1 and 27.2, which influence the casserole on the godet 1.1 and the sequence of the galette 1.2 towards higher wrap. The deflection rollers 27.1 and 27.2 are preferably designed to be adjustable, so that the degree of wrap around the godets 1.1 and 1.2 can be selected.

The embodiments of the device according to the invention shown in FIGS. 1 to 6 are characterized in particular by the fact that the guide shells of the godets are unheated. The heating of the threads is contactless exclusively borrowed by an energy transfer in the form of electromagnetic waves. By matching the wavelength of the infrared rays on the thread material and due to the plurality of juxtaposed infrared radiation body, a high radiation density is generated, which leads to intensive heating of the threads even with short heating sections and high thread speeds.

In principle, the embodiments of the device according to the invention shown in FIGS. 1 to 6 can also be used to form the heating means by elongate heat radiation bodies, which have, for example, an electrically heated radiation surface for generating the heat radiation. Such heat radiation body are well known, so that no further explanation takes place at this point. The radiation surfaces, which may be formed for example from a metal, have a high surface temperature of preferably greater than 200 ⁰ C.
