Description

  The present invention relates to a melt spinning apparatus for producing a plurality of multifilament yarns according to the superordinate conceptual part of claim 1.

  The above-described melt spinning apparatus is known from WO 2004/074155.

  In order to produce synthetic yarn, the plurality of melt spinning devices described above are combined in a machine room to form a set of spinning equipment. In this case, a high space utilization rate is desired. The larger the number of melt spinning apparatuses installed, the higher the production output of the spinning equipment. In addition to the mechanical pitch (installation interval) of the melt spinning apparatus, the productivity is mainly determined by the number of yarns that can be manufactured for each melt spinning apparatus. To that extent, there is a demand for forming the melt spinning apparatus as compact as possible and to produce as many yarns as possible.

  In such a type of melt spinning apparatus, a spinning apparatus, a cooling apparatus, a drawing apparatus, and a winding apparatus are arranged one above the other to form a vertical yarn traveling path. A spinning device having a spinning nozzle, a processing device having a plurality of godet units, and a winding device having a plurality of winding points each require different intervals between a plurality of yarns guided in parallel. , Yarn spreading or gathering (ie increasing and decreasing yarn spacing) cannot be avoided. However, it is sought to achieve in the yarn group that each multifilament yarn produced in the melt spinning apparatus has approximately the same properties. Therefore, yarn turning and spreading resulting in different yarn tensions within the multifilament yarn should be avoided as much as possible. Therefore, in the melt spinning apparatus, a turning device and a guide roller oriented in the vertical direction are used when transferring the yarn from the processing device to the winding position of the winding device. As a result, a yarn guide that is as compact as possible can be achieved by a plurality of deflections. However, such a thread guide also generates an undesirable thread tension. In particular, turning in the fixed turning means causes increased yarn wear.

Another melt spinning apparatus is known from WO 2004/0151 73 . In this melt spinning device, the godet of the processing device for drawing and drawing the yarn is oriented transversely with respect to the winding spindle of the winding device. Thereby, a winding apparatus and a processing apparatus can be formed as compact as possible. In this case, however, a single wound godet is preferably used in the stretching device in order to keep the godet within the machine pitch defined by the winding device. Therefore, in the case of a long protruding godet that guides the yarn group by a plurality of windings, it is almost impossible to combine this godet and the winding device to form one structural unit. However, in order to produce a drawn yarn having a large yarn fineness, a godet that is wound a plurality of times is essential in order to guide the yarn and to form a drawing force.

  An object of the present invention is to improve the melt spinning apparatus described at the beginning, and a yarn drawn in a godet unit that is wound a plurality of times can be supplied to a winding portion without spreading as much as possible without damaging the yarn. Is to do so.

  Another object of the present invention is to improve the melt spinning apparatus mentioned at the beginning so that as many as many drawn yarns (FDY) can be produced side by side in parallel.

  In the configuration according to the present invention that solves this problem, the guide godet is oriented laterally in the axial direction with respect to the godet of the godet unit below the stretching device, and the yarn travels in the yarn group during the transition. After 90 ° rotation of the plane, it can be guided by a single partial wrap in the guide godet.

  Preferred embodiments of the invention are defined by the features and combinations of features of the dependent claims.

  In the present invention, since the components that have a significant influence on the depth of the melt spinning apparatus are oriented in the same direction, the machine depth, which is mainly set by the winding apparatus, is the godet of the stretching apparatus. Excellent when used to install units. By rotating the yarn running plane of the yarn group, the yarn group can be supplied directly to a guide godet oriented laterally with respect to the godet of the godet unit provided in the drawing device without turning and spreading. The yarn group is rotated from the yarn traveling plane defined by the drawing device to a new yarn traveling plane defined by the guide godet by an angle in the range of 90 °. In this case, the yarn traveling plane can be understood as a plane drawn by a plurality of yarns guided side by side in parallel. Thereby, the spread of the yarn group for distributing the yarn to the winding position is minimized. The necessary turning can only be performed by rotating turning means such as guide godets.

  In the first embodiment of the present invention, supplying the stretched yarn to the winding position of the winding device is performed by single partial winding of the yarn group in the guide godet. For this purpose, a guide godet is arranged next to the side of the winding site, above the winding spindle. This allows the yarns to be distributed to the individual winding points after they run out of the guide godet.

  As an alternative, a second guide godet directed in the same direction above the winding spindle is arranged correspondingly to the guide godet. This second guide godet is arranged next to the side of the winding location. Thereby, in particular, the winding tension for winding the yarn around the winding position is affected by the driving of these guide godets.

  Furthermore, there is a possibility that the guide section formed between the two guide godets will be used for yarn processing. Therefore, according to another aspect of the present invention, the entanglement device is disposed between both guide godets.

  In order to be able to produce a plurality of yarns simultaneously, in another embodiment of the invention, the winding device is formed by two winding machines arranged side by side, each of these winding machines being It has a plurality of winding points. For this purpose, it is advantageous if the guide godet is held in the middle above the winder. Thereby, the depth of the winding device can be kept relatively small even when the number of yarns is large. For improved yarn guides, the winders are preferably implemented mirror-symmetrically with respect to each other so that the yarn group can be distributed out of the plane of symmetry after running out of the guide godet. it can.

  The distribution and supply of the yarn to the winding part is performed according to an aspect of the present invention in which a plurality of turning rollers are provided between the guide godet and the winding part. Each of these turning rollers is disposed directly upstream of one traverse device at the winding position. Thereby, a thread | yarn can be supplied to a winding location with little thread | wear.

  Regarding the yarn stability when guiding a plurality of yarns as one yarn group, the melt spinning apparatus according to the present invention can be further improved by the following configuration. That is, a guide means is provided between the guide godet and the last godet of the stretching apparatus. By this guide means, the yarn traveling plane of the yarn group is changed by a predetermined angle in the range of 90 °. Thereby, the running of the yarn group from the last godet of the drawing device and the supply of the yarn of the yarn group to the guide godet are remarkably stabilized.

  Another aspect of the present invention is particularly advantageously implemented so that as many yarns as possible can be obtained within the mechanical pitch provided by the spinning nozzle. In this embodiment, the spinning nozzles are each formed as a double nozzle, and two multifilament yarns can be extruded for each spinning nozzle by the double nozzle. Thereby, a large number of yarns can be formed in parallel in the spinning device with a very compact arrangement of the spinning nozzles. Therefore, the row of spinning nozzles is oriented transversely to the axis of the godet unit of the drawing device, and together with the free end of the godet unit and the free end of the take-up spindle of the winding device forms the machine operating side. A possibility arises. In order to stabilize the yarn traveling path, a guide means may be provided between the spinning nozzle and the drawing device. By this guide means, the yarn traveling plane is changed by an angle in the range of 90 °.

  Despite the compact configuration of the spinning device, in order to uniformly cool the individual extruded multifilament yarn, the cooling device for cooling the yarn has a plurality of cooling devices each having a gas permeable cylindrical wall. One embodiment of the present invention having a tube is particularly advantageous. These cooling cylinders are arranged in the blower chamber. Therefore, each yarn of the yarn group can be cooled under substantially the same conditions.

  When the spinning nozzle is configured as a double nozzle, an embodiment of the present invention in which each spinning nozzle is arranged corresponding to one of a plurality of cooling cylinders is advantageously used. In this case, the cooling cylinder is divided into two separate cooling regions. Therefore, a plurality of yarns can be simultaneously extruded and cooled for each spinning nozzle and cooling cylinder.

  The melt spinning apparatus according to the present invention is particularly suitable for producing drawn yarn (FDY).

  The present invention will now be described in detail with reference to several embodiments of a melt spinning apparatus.

1 is a schematic side view showing a first embodiment of a melt spinning apparatus according to the present invention. It is a schematic front view of the aspect shown in FIG. It is a schematic side view which shows another embodiment of the melt spinning apparatus which concerns on this invention. It is a schematic front view which shows another embodiment of the melt spinning apparatus which concerns on this invention.

  1 and 2 schematically show a first embodiment of a melt spinning apparatus according to the present invention from a plurality of viewpoints. FIG. 1 shows a side view of the present embodiment, whereas FIG. 2 shows a front view of the present embodiment. The following description applies to both drawings unless specifically associated with one of the two drawings.

  This embodiment has a spinning device 1, a cooling device 3, a stretching device 4, and a winding device 22. These devices are arranged side by side in the vertical direction, whereby a yarn traveling path mainly oriented in the vertical direction can be obtained.

  The spinning device 1 has a spinning beam 9. The lower surface of the spinning beam 9 supports a plurality of spinning nozzles 2.

  As can be seen from FIG. 2, the spinning beam 9 holds two spinning nozzles 2. These spinning nozzles 2 are respectively formed as double nozzles (Doppelduese) 8.1, 8.2. Each double nozzle 8.1, 8.2 held by the spinning beam 9 is connected to one multi-stage pump 6 via two separate melt lines. The multistage pump 6 is preferably formed as a planetary gear pump. In this case, two separate planetary gear sets are arranged corresponding to each double nozzle 8.1, 8.2. The multistage pump 6 is driven via one pump drive unit 7. In this case, the polymer melt is supplied via the melt supply unit 5 connected to the multistage pump 6.

  A cooling device 3 is provided below the spinning device 1. The cooling device 3 has a blower chamber 10. The blower chamber 10 is connected to an air conditioner (not shown). A plurality of cooling cylinders 11.1, 11.2 are arranged inside the blower chamber 10. The cooling cylinders 11.1 and 11.2 are arranged corresponding to the spinning nozzle 2. Since the cooling cylinders 11.1 and 11.2 each have one gas-permeable cylinder wall, the refrigerant introduced into the blower chamber 10 is uniformly inside the cooling cylinders 11.1 and 11.2. Can flow into.

  As is particularly clear from the drawing of FIG. 2, each cooling cylinder 11.1, 11.2 has one separating wall 12 in the middle region. This separating wall 12 forms two separate cooling zones in the cooling cylinders 11.1 and 11.2. Accordingly, a filament bundle pushed out by one of the double nozzles 8.1 and 8.2 can be introduced into each cooling region.

  The configurations of the blower chamber 10 and the cooling cylinders 11.1, 11.2 are exemplary. Basically, the blower chamber 10 can be formed by an upper chamber and a lower chamber connected to each other via a thin metal plate with holes. In this case, both chambers of the blower chamber are penetrated by one cooling cylinder having a gas-permeable wall in the upper chamber and a closed wall in the lower chamber. The connection with the air conditioner is made through a lower chamber of the air blowing chamber.

  As an alternative, however, the cooling cylinders 11.1, 11.2 can also be formed by a blowing wall oriented laterally with respect to the spinning nozzle 2, so that a cooling air flow directed laterally can be formed. It is.

  As is clear from FIGS. 1 and 2, the cooling cylinders 11.1, 11.2 open into a cooling box 13 that guides the yarn for cooling.

  Since each extruded multifilament yarn is formed by a large number of filament strands, the filaments are collected for each yarn at the outlet of the cooling device 3. For this purpose, a plurality of collective yarn guides 14 and an oil application device 15 as a preparatory process are provided. In this embodiment, the oil agent applicator 15 is shown as a roller type oil agent applicator, for example. However, basically, a pin type oil application device can also be used.

  The drawing device 4 is disposed on the downstream side of the cooling device 3 in order to draw out and draw a plurality of yarns extruded as one yarn group. The stretching device 4 has two godet units 16.1, 16.2 in the present embodiment. These godet units 16.1 and 16.2 are formed in the same manner, and in the present embodiment, include godets 17 that are driven and associated rollers 18 that are rotatably supported. The godet 17 is driven by a godet driving device 31. The yarn is guided as a yarn group 33 with a plurality of windings in the godet units 16.1 and 16.2. In this case, a speed difference is formed between the godets 17 provided in the godet units 16.1 and 16.2, whereby the yarns of the yarn group 33 can be drawn.

  During the transition from the cooling device 3 to the drawing device 4, a first rotation of 90 ° of the yarn travel plane is necessary. This is because the yarn traveling plane drawn by the spinning nozzle extends by being shifted by 90 ° with respect to the yarn traveling plane formed by the godet units 16.1, 16.2. In this case, a plane on which the yarns of the yarn group 33 are guided side by side is called a yarn traveling plane.

  In order to transfer the yarn group 33, a guide means 19 is provided between the oil application device 15 and the first godet 17 of the godet unit 16.1 of the stretching device 4. By this guide means 19, the yarn group can be twisted and at the same time the yarns can be guided against each other with a predetermined processing interval.

  As can be seen from both the drawings of the first embodiment, a guide godet 20.1 is disposed downstream of the stretching device 4. The guide godet 20.1 is arranged on the downstream side of the last godet 17 of the godet unit 16.2, and thereby the yarn group 33 can be pulled out from the godet unit 16.2. For this purpose, the guide godet 20.1 is oriented transversely in the axial direction with respect to the godet 17 of the godet unit 16.2. As a result, the yarn can be guided by a single partial winding in the guide godet 20.1 by the rotation of the yarn travel plane of 90 ° during the transition.

  The guide godet 20.1 is held by the godet support 34. The godet support 34 is supported by the machine frame 30 of the winding device 22. The godet driving unit 31 disposed so as to correspond to the guide godet 20.1 is held on the side of the godet support 34 that is positioned opposite to the guide godet 20.1.

  As can be seen from the drawing of FIG. 1, a second guide godet 20.2 is disposed corresponding to the guide godet 20.1. The second guide godet 20.2 is disposed next to the godet support 34 on the side of a plurality of winding locations 23.1 to 23.4 provided in the winding device 22. An entanglement device 21 is provided between the guide godets 20.1 and 20.2. By this entanglement device 21, the yarns of the yarn group 33 can be processed separately from each other.

  The winding device 22 has a plurality of winding locations 23.1 to 23.4. At these winding points 23.1 to 23.4, a plurality of yarns of the yarn group 33 are wound to form one package 26, respectively. These winding points 23.1 to 23.4 are formed in the same manner, and each have one turning roller 27 and one traverse unit 28. A plurality of packages 26 are in this case wound simultaneously on one winding spindle 24.1 or 24.2. The winding spindles 24.1, 24.2 are projected and held in the winding revolver 25 and are alternately guided to the operation area and the exchange area. In order to lay the yarn of the yarn group 33 on each package 26, a pressing roller 29 is provided. The pressing roller 29 is applied to the peripheral surface of the package 26. The winding revolver 25 and the pressing roller 29 are movably held by the machine frame 30.

  The drive unit of the winding device 22 is not shown in FIGS. This is because such a type of winding device, also called a winding revolver in the industry, is well known. In this case, the godet driving parts 31 of the guide godets 20.1, 20.2 preferably form a control unit that is fed and controlled in common.

  In the embodiment shown in FIGS. 1 and 2, the yarn traveling path of the yarn group 33 is drawn to explain the function. In this case, a number of delicate filament strands are extruded from the polymer melt by both double nozzles 8.1, 8.2. These filament strands are gathered together by cooling and oil application after cooling to form a total of four multifilament yarns. Basically, pre-entanglement of the filaments is performed in addition to the oil agent application, thereby forming a yarn combination necessary for yarn processing.

  Next, the yarn group 33 formed of four yarns is pulled out from the spinning nozzle 2 by the first godet 17 of the godet unit 16.1. In this case, the yarn group is transferred from the first yarn traveling plane drawn by the row of spinning nozzles 2 to the yarn traveling plane shifted by 90 °. The second yarn travel plane is defined by the axial orientation of the first godets 17 of the goded units 16.1, 16.2 oriented transversely to the row of spinning nozzles 2.

  In the drawing device 4, the yarn group 33 is drawn by the speed difference between the godet units 16.1 and 16.2. For this purpose, it is advantageous if the godets 17 of the godet units 16.1, 16.2 are configured to be heated.

  What should be clarified at this point is that the configurations of the godet units 16.1, 16.2 are exemplary. Basically, the godet units 16.1, 16.2 may alternatively be formed by two godets that are driven and have a heated guide outer peripheral surface. In addition, a plurality of godets with associated rollers, a plurality of godets, or a plurality of godet units made up of individual godets can be used.

  After the yarn group 33 is drawn, the yarn group 33 is pulled out by a guide godet 20.1 disposed on the downstream side of the drawing device 4. In this case, the yarn group 33 is guided so as to deviate from the yarn traveling plane defined for processing, and is transferred to a guide plane twisted by 90 °. This guide plane is defined by the axial orientation of the guide godet 20.1. In this case, the guide godet 20.1 is oriented substantially laterally relative to the godet 17 of the godet unit 16.1, 16.2. The yarn path between the godet unit 16.2 and the guide godet 20.1 can advantageously be used for the shrinking process. In this case, the guide godet 20.1 is driven independently of the godet guide 16.2. Further, the guide god 20.1 may be configured to be heated.

  For further processing, the yarn group 33 is fed to the entanglement device 21 held between the guide godets 20.1, 20.2. In this case, the yarn tension for the entanglement of the yarns of the yarn group 33 can be suitably adjusted by the different circumferential speeds of the guide godets 20.1, 20.2. For this purpose, the guide godet 20.2 is driven by the godet driving unit 31. As a result, an independent winding tension in the yarns of the yarn group 33 can be formed.

  Finally, the yarns of the yarn group 33 are distributed to the individual winding points 23.1-23.4 and wound up to form one package 26 each. Based on the same processing by a plurality of soft deflections by the rotating deflection means, each yarn of the yarn group 33 has substantially the same characteristics. As a result, the package 26 can be formed with substantially the same winding tension.

  The number of yarns selected in the embodiment shown in FIGS. 1 and 2 that are simultaneously extruded, drawn, and wound is exemplary. Basically, more than four yarns are usually produced for each melt spinning device of the spinning facility. The number of yarns is not important for the description of the present invention.

  FIG. 3 shows a schematic side view of another embodiment of the melt spinning apparatus according to the invention. Since the present embodiment is almost the same as the embodiment shown in FIG. 1, only the differences will be described in this place, and the above description is referred to for others.

  In the embodiment of the apparatus according to the present invention shown in FIG. 3, the guide means 32 and the guide godet 20 are arranged between the drawing device 4 and the winding device 22 for guiding the yarn group 33. The guide godet 20 is held next to the godet support 34 on the side of the winding locations 23.1 to 23.4. Thereby, the yarn of the yarn group 33 guided by being partially wound around the guide godet 20 can be directly supplied to the winding points 23.1 to 23.4.

  Guide means 32 are provided for twisting the yarn running surface of the yarn group 33 after running from the godet unit 16.2 by 90 °. Thereby, the running of the yarn group in the godet unit 16.2 and the supply of the yarn group to the guide godet 20 can be stabilized by the guide means 32. The yarn group 33 is twisted in a straight yarn traveling path without turning and spreading.

  The function of the embodiment shown in FIG. 3 is the same as the function of the embodiment of FIGS. 1 and 2, so the above description is referred to at this point and will not be further described.

  The diverting means shown in FIG. 3 for transferring the yarn group from the drawing device to the winding device can preferably also be incorporated into the embodiment shown in FIG. Similarly, the embodiment of the melt spinning apparatus shown in FIG. 3 can be practiced without additional guide means.

  FIG. 4 is a front view schematically showing still another embodiment of the melt spinning apparatus according to the present invention. Since this embodiment is almost the same as the above-described embodiment shown in FIG. 3, in order to avoid repetition, only the differences will be described, and the rest will be referred to the above description.

  In the embodiment shown in FIG. 4, the winding device 22 is formed by two winding machines 35.1, 35.2 arranged side by side. The winders 35.1, 35.2 are arranged mirror-symmetrically with respect to each other and have the same structure. Each of the winding machines 35.1, 35.2 has a plurality of winding points 23.1-23.4. The winding device 22 shown in FIG. 3 therefore shows a side view of the winding machines 35.1, 35.2. To that extent, reference is made to the explanation made in FIG.

  Winders 35.1 and 35.2 are driven synchronously. As a result, a plurality of yarns of the yarn group 33 can be wound to form a package. The yarn group 33 is supplied via a guide godet 20 disposed on the upstream side of the winding device 22. For this purpose, the guide godet 20 is held above the winders 35.1, 35.2 in the support frame 37 in the middle of both winders 35.1, 35.2. The guide godet 20 protrudes from the godet support 34 and is driven via an electric motor.

  Since the yarn group is distributed after the yarn of the yarn group 33 from the guide godet 20, the winders 35.1 and 35.2 can wind up the same number of yarns to form a package.

  On the support frame 37, the stretching device 4 is arranged above the winders 35.1, 35.2. The stretching apparatus 4 is also formed by two godet units 16.1 and 16.2 in the present embodiment as well. The godet units 16.1, 16.2 each have two godets 17 to be driven. The godets of the godet units 16.1, 16.2 are preferably driven as godet pairs so that the speed difference between the godet units 16.1, 16.2 is adjusted for the drawing of the yarn. Is possible.

  The axis of the godet 17 of the godet units 16.1, 16.2 is oriented identically to the winding spindles 24.1, 24.2 of the two winding machines 35.1, 35.2. On the other hand, since the guide godet 20 disposed between the godet unit 16.2 and the winding device 22 is oriented sideways, the godet unit 16.2 to the guide godet 20 During the yarn transition, the yarn travel plane of the yarn group is twisted by an angle in the range of 90 °. In this case, another guide means is not provided between the godet unit 16.2 and the guide godet 20.

  In the present embodiment, godet units 16.1 and 16.2 are arranged in one godet box 36.1 and 36.2, respectively. Thus, preferably the heated godet 17 is used in the godet unit 16.1, 16.2, so that it is insulated inside the godet box 36.1, 36.2 for yarn processing. An environment is created.

  The spinning device 1 and the cooling device 3 are formed in the same manner as the embodiment shown in FIGS. In this case, the number of spinning nozzles is doubled. Therefore, a total of four double nozzles 8.1-8.4 are provided. As a result, two yarns can be simultaneously extruded for each spinning nozzle location. For further explanation of this point, reference is made to the above description with respect to FIG.

  Similarly, in the embodiment shown in FIG. 4, the spinning nozzle 2 may be positioned in a row-like arrangement extending laterally with respect to the godet axis of the godet 17. In that case, the yarns of the yarn group 33 are transferred from the spinning plane defined by the nozzles to the processing plane defined by the godet units 16.1, 16.2. In this case, a guide means 19 is provided. As a result, the yarn travel plane of the yarn group is twisted by an angle in the range of 90 °. The guide means 19 is disposed immediately upstream of the stretching device 4. In this case, the plurality of yarns are guided together in parallel as one yarn group.

  Between the drawing device 4 and the spinning device 1, a collecting yarn guide 14 and an oil coating device 15 as a preparation processing device are arranged. As a result, the filament strands extruded for each spinning nozzle are collected to form a plurality of yarns.

  The embodiment illustrated in FIG. 4 provides a particularly compact arrangement for producing a plurality of yarns at one spinning point. The function of the embodiment shown in FIG. 4 is the same as that of the above-described embodiment, and will not be further described here.

  The embodiment shown in FIGS. 1-4 is exemplary in the structure and arrangement of the stretching apparatus. In principle, additional processing steps and processing devices may be incorporated between the spinning device and the winding device.
