Description

[Technical Field]

[0001] The invention relates to a method for producing a winding package with a synthetic yarn according to the preamble of claim 1 and to an apparatus for producing a winding package with a synthetic yarn according to the preamble of claim 10. [Background technology]

[0002] When producing composite yarns, the yarn produced from the polymer melt is drawn and processed before being wound onto a winding package, which serves to store the yarn and then feeds it to further processing processes.

[0003] The winding package includes a tube onto which the composite yarn is wound in a winding device. To allow continuous extrusion and production of the yarn in the melt spinning process, the yarn is wound onto the winding package continuously without any significant interruptions.

[0004] For this purpose, the winding device described above is used, which has two winding spindles cantilevered on a rotatably supported winding turret.

[0005] The winding spindles can be guided alternately into a winding position and an unwinding position by rotation of the winding turret, where the yarn is wound onto the respective winding spindle into a winding package.

[0006] As soon as the winding package has a predetermined final diameter, the winding spindle with the winding package is guided to the unwinding position, where the yarn is wound around the winding package to form the final winding, and then the winding spindle held by the winding position is captured and detached, where the yarn is then wound onto a new winding package.

[0007] The winding package held in the unwinding position is removed from the winding spindle after braking and fed to a further processing process. At this time, it is necessary that the loose yarn end occurring at the final winding portion is adhered to the periphery of the winding package as much as possible, because undesirable unraveling may occur during removal of the winding package from the winding spindle and during transport.

[0008] In order to fasten loose yarn ends of a winding package around the periphery of the winding package precisely when the winding is changed, a winding device of the type mentioned at the outset is known from DE 44 13 885 A1, in which the winding spindle is assigned a yarn fastening application device having a nozzle for wetting the yarn with water or an oil medium.

[0009] During package change, the nozzle is guided toward the yarn wound as the final winding. The yarn is then moistened before being separated, which allows the yarn to adhere as closely as possible to the periphery of the winding package. To support this operation, the yarn fixing and application device may have a pressure roller that contacts the periphery of the winding package. The water or oil to be used must ensure that the loose yarn ends can be properly fixed. Summary of the Invention [Problem to be solved by the invention]

[0010] It is therefore an object of the present invention to provide a method and an apparatus which allow for secure fixation of loose yarn ends in a winding package. [Means for solving the problem]

[0011] As regards the method, this problem is solved according to the invention by a method having the features of claim 1.

[0012] The problem with the device is solved according to the invention by a device having the features of claim 10 .

[0013] According to one aspect of the present invention, there is provided a method for producing a winding package comprising a composite yarn by extruding multiple filaments from a plastic melt, gathering the filaments into a composite yarn, wetting the filaments with a first liquid as they are gathered, drawing the composite yarn using a godet, and winding the composite yarn onto a winding package using a winding device. To remove the winding package from the winding device, a large yarn end of the winding package is secured to the winding package by a second liquid.

[0014] This simultaneously enables secure fixation of loose yarn ends and good oiling of the yarn to be produced before winding with so-called spin finishing, and additionally ensures secure removal and removal of the winding package after winding.

[0015] According to one aspect of the method, the yarn is severed before the winding package is removed, and after the severing, a second liquid is applied to the winding package at the working point.

[0016] This allows both accurate and precise positioning and application of the second liquid on the winding package, which can be performed regularly and at a consistent position, since the second liquid is brought to and applied to the associated final winding of the winding package.

[0017] According to another aspect of the method, the first liquid used to gather the multiple filaments into a yarn is different from the second liquid used to secure the loose yarn ends.

[0018] This offers the advantage that the optimum liquid can be used for oiling and for fixing the thread or loose thread ends.

[0019] According to another aspect of the method, the first liquid used to gather the multiple filaments into a single yarn is the same as the second liquid used to secure the loose yarn ends.

[0020] This provides the advantage of eliminating the need for separate storage of different liquids, which requires additional tanks and / or additional mixing and control of other liquids.

[0021] Furthermore, this configuration offers considerable liquid saving potential, as only one liquid is used both for spin finishing and for fixing the loose yarn ends.

[0022] Another aspect of the method involves providing a continuous supply of a first liquid for use in gathering the multiple filaments into a single yarn, and an intermittent supply of a second liquid for use in securing the loose yarn ends.

[0023] Depending on the method step, it is necessary to further supply the respective liquid at the appropriate point in the process. The first liquid used for consolidating the filaments and for spin finishing must be supplied continuously during the production process of the filaments from the melt and during extrusion, thereby ensuring reliable production. In contrast, the fixation of the loose yarn ends is not carried out continuously, but rather in conjunction with the unwinding process from the winding device. Therefore, the supply of this liquid, also referred to as the second liquid, can be interrupted when fixation of the yarn is not required and is therefore carried out intermittently.

[0024] According to another embodiment of the method, the first and / or second liquid acts as a lubricant, an anti-adhesion agent and / or an anti-static agent. The first or second liquid has a composition that allows the yarn to be fed and unwound or wound without problems. The first liquid is preferably used for spin finishing.

[0025] To this end, the respective liquids act as lubricants to prevent possible friction in the corresponding components of the winding device.Furthermore, it is desirable that the first or second liquid also act as an anti-adhesion agent, thereby preventing adhesion during winding or unwinding.

[0026] Furthermore, the liquid also acts as a static inhibitor which prevents static charging on the yarn, allowing the yarn to be wound or unwound without problems.

[0027] According to another aspect of the method, the first liquid comprises an emulsion comprising water and oil.

[0028] For spin finishes when combining multiple filaments into a single yarn, water-oil emulsions are particularly preferred, particularly as oil-water compositions act as lubricants, anti-adhesion agents, and static suppressants.

[0029] According to another configuration of the method, the second liquid comprises water, a binder, an adhesive, or an emulsion comprising water and oil.

[0030] The second liquid used to fix the loose yarn ends to the winding package should provide particularly good adhesion of the loose yarn ends to the winding package.

[0031] For example, emulsions of water, suitable binders, adhesives and / or first liquids can be used, each of which has its own specific advantages and can be adapted to the appropriate yarn format.

[0032] According to another configuration of the method, the first liquid and / or the second liquid have different compositions depending on the yarn to be produced, in particular IDY, POY, FDY, HOY, BCF.

[0033] IDY (Industrial Yarn) is also called industrial yarn, BCF (Bulk Continuous Filament) is also called carpet yarn, POY (Pre Oriented Yarn) is also called pre-drawn yarn, FDY (Full Drawn Yarn) is also called fully drawn yarn, and HOY (High Oriented Yarn) is also called highly drawn yarn.

[0034] Depending on the yarn type or thread type used, other plastics and plastic compositions are required for the filament melt, which also leads to corresponding differences in count, so that special liquid compositions are required for the use of the spin finish or for fixing the loose yarn ends in the winding package. The count can also affect the required amounts of the respective liquids needed for the spin finish and for fixing the loose yarn ends.

[0035] According to another aspect of the present invention, there is provided an apparatus for producing a winding package with a synthetic yarn, in particular configured for carrying out a method according to at least one of the above-described configurations.

[0036] The apparatus includes a spinning device for extruding multiple filaments from a plastic melt, the filaments being gathered into a single thread using an oil nozzle, wherein the multiple filaments are wetted with a first liquid using the oil nozzle, and a winding device for winding the thread from the spinning device into a winding package, the winding device having a winding spindle and a traverse device for forming the winding package, and a yarn fixing and dispensing device. The first liquid is supplied to the oil nozzle, and the second liquid is supplied to the yarn fixing and application device.

[0037] This device offers the advantage that the best possible liquid is supplied to the spinning unit and the winding unit respectively, and the optimum liquid can be used depending on the yarn to be lubricated or fixed.

[0038] According to one configuration of the device, a first liquid is continuously supplied to the oil nozzle using a first supply line, and a second liquid is intermittently supplied to the yarn fixing application device using a second supply line.

[0039] When extruding a large number of filaments, the formation and production of the filaments is continuous, so the supply of the first liquid must also be continuous, and thread fixation is only necessary after a predetermined winding time, and is therefore interrupted and intermittent.

[0040] Therefore, different supply forms for the first liquid and the second liquid are required for each oil nozzle or thread fixing application device.

[0041] According to another configuration of the device, the first liquid and the second liquid are provided in one common liquid dispenser or in different liquid dispensers of the oil nozzle and / or the thread fixing device.

[0042] This arrangement provides the advantage that only one liquid dispenser needs to be provided if the liquids are the same, whereas the separation into different liquid dispensers prevents undesired mixing of the liquids.

[0043] The method according to the invention and the device according to the invention will now be described in more detail by way of relevant examples with reference to the accompanying drawings. [Brief explanation of the drawings]

[0044] [Figure 1] 1 is a front view schematically illustrating an embodiment of a winding device equipped with a yarn fixing and applying device. [Figure 2] 1 is a side view schematically showing an embodiment of a spinning device equipped with an oil agent nozzle. FIG. [Figure 3] 1 is a flow chart illustrating method steps for manufacturing a winding package with a composite yarn. DETAILED DESCRIPTION OF THE INVENTION

[0045] FIG. 1 shows a front view of an embodiment of a winding device 100 for continuously winding yarns 12.1 to 12.3, and FIG. 2 shows a schematic side view of an embodiment of a spinning device 200.

[0046] The embodiment of the winding device 100 shown in FIG. 1 winds the yarns 12.1 to 12.3 produced by the spinning device 200 onto a winding package 13 at winding points 4.1 to 4.3.

[0047] In the following, the winding points 4.2-4.3 or the associated positions in the spinning device 200 will be described in particular with respect to the winding point 4.1 or the associated position for the yarn 12.1, since these are configured identically.

[0048] 1 and 2 each show a reference coordinate system having X, Y, and Z directions, which makes it possible to clarify the respective viewing directions. In the reference coordinate system XYZ in Fig. 1, the X direction indicates the longitudinal extension direction of the winding device 100, the Y direction indicates the depth extension direction of the winding device 100, and the Z direction indicates the height extension direction of the winding device 100.

[0049] In the reference coordinate system XYZ in FIG. 2, the X direction indicates the longitudinal extension direction of the spinning apparatus 200, the Y direction indicates the depth extension direction of the spinning apparatus 200, and the Z direction indicates the height extension direction of the spinning apparatus 200.

[0050] The winding device 100 is positioned below the spinning device 200 in the Z direction, so that the yarns 12.1 to 12.3 produced by the spinning device 200 can be wound by the winding device 100 at the associated winding points 4.1 to 4.3.

[0051] The winding device 100 shown in FIG. 1 comprises a winding turret 2 which holds two cantilevered rotatably supported winding spindles 3.1, 3.2.

[0052] The winding spindles 3.1, 3.2 are arranged on the winding turret 2 at 180° offset from each other. Spindle motors (not shown) are arranged on the backside of the winding turret 2 for the winding spindles 3.1, 3.2. The winding turret 2 is rotatably supported on the machine frame 1 and connected to a turret drive (not shown). By means of the turret drive, the winding spindles 3.1, 3.2 can be rotated by the winding turret 2 alternately between a winding position and an unwinding position.

[0053] In the unwinding position, the winding spindles 3.1, 3.2 cooperate alternately with the pressure roller 5 and the winding points 4.1 to 4.3. In this example, a total of three winding points 4.1 to 4.3 are arranged next to one another in the X direction on the machine frame. Since the winding points 4.1 to 4.3 are identically constructed, the following description will focus more on the winding point 4.1.

[0054] The winding station 4.1 has a traverse device 8, upstream of which a head yarn guide 11 is arranged for feeding the yarns 12.1-12.3 in the yarn path. Between the traverse device 8 and the winding spindles 3.1, 3.2, the pressure roller 5 is rotatably supported on a roller holder 6. The roller holder 6 is pivotally connected to the machine frame 1. The traverse device 8 has traverse means (not shown in detail) at the associated winding stations 4.1-4.3 for guiding each yarn 12.1-12.3 back and forth so that the yarns 12.1-12.3 are laid around the winding package 13 at the associated winding station 4.1-4.3.

[0055] For this purpose, the traverse device 8 is connected to a traverse drive device 9 (not shown).

[0056] Between the winding spindles 3.1 and 3.2, a change-cutting device 14 is positioned on the machine frame 1, by which the yarn 12 at the winding point 4.1 and the adjacent yarns 12.2-12.3 at the winding points 4.2 and 4.3 are guided and cut during the winding change. In the situation shown in Figure 1, a winding change is performed between the winding spindles 3.1 and 3.2, whereby the winding spindle 3.1 is in the unwinding position with several winding packages 13, and the winding spindle 3.2 is in the winding position for winding a new package. The change-cutting device 14 is pivoted between the winding spindles 3.1 and 3.2 and has already cut off the yarns 12.1-12.3, so that each winding package 13 has a loose yarn end 31.

[0057] Such an exchange disconnecting device 14 is also known from DE 10 2009 007 759 A1, and therefore reference is made to the cited publication in this document and no further explanation is given.

[0058] Next to the change-cutting device 14, a fixed yarn application device 15 is provided, which is held on the side of the machine frame 1.

[0059] 1, the yarn fixing application device 15 has a holder 18 in a fixed position, by means of which the winding package 13 mounted on the respective winding spindle 3.1, 3.2 can be applied with a yarn fixing liquid, also referred to below as second liquid 28, by means of a liquid applicator 19 at an application point WS, which is preferably located at the final winding point 29 of the winding package 13.

[0060] The carrier 18 is held by a pivoting arm 17 which can be guided back and forth by a motion actuator 16 between a rest position and the operating position shown.

[0061] The pivoting arm 17 is pivotably held on the machine frame 1. In the view shown in Fig. 1, the pivoting arm 17 with the holder 18 is in the operating position and secures the loose yarn end 31 to the winding package 13 at the application point WS. The second liquid 28 that secures the loose yarn end 31 to the winding package 13 is prepared in a liquid dispenser 33, which is connected via a first supply line 50 to the holder 18 of the yarn clamping device 15, so that the second liquid 28 can be regularly supplied to the yarn clamping device 15.

[0062] FIG. 1 also shows another embodiment in which the second liquid 28 stored in the liquid dispenser 33 is connected to the oil agent nozzles 42.1 to 42.3 of the spinning apparatus 200 via a third supply line 53, thereby enabling the second liquid 28 for yarn fixation to be supplied to the oil agent nozzles 42.1 to 42.3 as well.

[0063] The third supply line 53 is only necessary if only one liquid dispenser is provided for both the winding device 100 and the spinning device 200 .

[0064] 2 shows a schematic side view of the spinning apparatus 200 in the longitudinal direction X. The spinning apparatus 200 is also shown in two embodiments. The third supply line 53, which supplies the first liquid 27 to the oil nozzles 42.1 to 42.3 for spin finishing, is connected in one embodiment to the liquid dispenser 33 of the winding apparatus 100 and supplies the second liquid 28 to the liquid application device 15.

[0065] In the embodiment shown in FIG. 2, the first supply line 51 is further connected to the oil nozzles 42.1 to 42.3 for applying the first liquid 27 prepared in the liquid dispenser .

[0066] FIG. 2 also shows a third embodiment, in which oil nozzles 42.1-42.3 receive a first liquid 27 for spin finishing and a second liquid for yarn fixation supplied from liquid dispensers 33 and 34.

[0067] The spinning apparatus 200 has a spinning beam 40 having a plurality of spinning nozzle plates 41.1-41.3 for extruding a plastic melt to form filaments 120, and the plastic melt supplied via spinning pumps 44.1-44.3 is extruded through the capillaries of the spinning nozzle plates 41.1-41.3 to form the filaments 120.

[0068] The filaments 120 are gathered into single threads 12.1-12.3 by the respective oil nozzles 42.1-42.3 and guided to the winding device 100 using thread guides 43.1-43.3, which then pull out and guide the threads 12.1-12.3 via the associated withdrawal godets 20.1-20.2.

[0069] The drawing godets 20.1-20.2 may be paired in the case of POY yarns. When producing other yarns such as IDY, FDY, BCF and HOY, additional godets may be required to temperature condition and draw the respective yarns 12.1-12.3.

[0070] A cooling device 45 is also shown for cooling the plastic melt or filament 120, through which cooling air is directed towards the filament, so that the filament can be drawn using godets 20.1-20.2 and has sufficient strength.

[0071] Using the oil agent nozzles 42.1 to 42.3, a large number of filaments 120 are gathered into single threads 12.1 to 12.3, and these threads 12.1 to 12.3 are supplied to the winding device 100 using the respective thread guides 43.1 to 43.3.

[0072] The withdrawal or feeding is carried out towards the winding device by means of godets 20.1-20.2.

[0073] For FDY yarns, an additional godet is required, which can appropriately temperature-condition and stretch the yarn 12.1. The same is true for HOY, IDY, and BCF yarns. Only for POY are two godets 20.1-20.2 sufficient.

[0074] First liquid 27 is supplied from liquid dispenser 34 via first supply pipe 51 to each of oil agent nozzles 42.1 to 42.3.

[0075] In another embodiment, the supply to the oil nozzles 42.1 to 42.3 is carried out exclusively via a supply line 53 connected to the liquid dispenser 33 or the liquid dispenser 34, which prepares the second liquid 28 that is also used for thread fixation using the thread fixation application device 15.

[0076] In the third embodiment, the supply to the oil agent nozzles 42.1 to 42.3 is performed from the liquid dispenser 33 via a third supply line 53 and via a first supply line 51 of the liquid dispenser 34 that prepares the first liquid 27.

[0077] The first liquid 27 and the second liquid 28 can be emulsions or mixtures of equal composition. However, the first liquid 27 and the second liquid 28 can also have different compositions. For example, the first liquid 27 can be an emulsion of water and oil for a spin finish, while the second liquid 27 contains water, a binder, an adhesive, and / or an emulsion for yarn fixation, the emulsion having a different water and oil composition than the first liquid 27.

[0078] Depending on which yarn 12 is to be produced, the respective plastic melts extruded by the spinning nozzle plates 41.1-41.3 are different. The spinning nozzle plates 41.1-41.3 then have different capillary sizes for the respective yarn types. The yarn types can be, for example, IDY, POY, FDY, HOY and / or BCF.

[0079] Each yarn type also has a different yarn count, which requires different liquids to be supplied to the yarns in the oil nozzles 42.1-42.3 and in the yarn fixing and application device 15. This is because different amounts and qualities of liquid should be supplied depending on the yarn type and yarn count, thereby ensuring the desired quality of spin finish in the spinning device 200 and of fixing the loose yarn 31 in the spinning device 100.

[0080] The first liquid 27 is preferably supplied to each of the oil agent nozzles 42.1 to 42.3 continuously.

[0081] For this purpose, a corresponding displacement or pumping device may be provided which serves to continuously supply the first liquid 25 .

[0082] The supply of the second liquid 28 is preferably carried out intermittently via a corresponding pump device controlled or regulated by the control device of the winding device 100, so that the second liquid 28 can be supplied to the yarn fixing application device 15 at the right time and in sufficient amount.

[0083] FIG. 3 shows a schematic flow chart illustrating the main method steps for producing the winding package 13.

[0084] In a first method step S10, a plastic melt is extruded to form a multiplicity of filaments 120 using the spinning nozzle plates 41.1-41.3.

[0085] In a further method step S11, the filaments 120 are gathered into single threads 12.1 to 12.3 by oil nozzles 42.1 to 42.3, respectively, and simultaneously cooled by a cooling device 45.

[0086] Cooling device 45 is preferably a cylindrical housing that at least partially surrounds the width of extruded filament 120 and allows cooling air to be directed towards filament 120 .

[0087] In a further step S12, the yarn is oiled for spin finishing by application of a first liquid 27. This oiling takes place via oil nozzles 42.1-42.3, which preferably contain a first liquid 27, which is supplied from a liquid dispenser 34 via a first supply line 51.

[0088] The supply to the oil nozzles 42.1 to 42.3 can also take place exclusively via the liquid dispenser 33 with the second liquid 28 or in combination.

[0089] In a further step S13, each thread 12.1 to 12.3 is pulled through the godets 20.1 to 20.3 and wound on the associated winding points 4.1 to 4.3 of the winding device 100, respectively.

[0090] In a further step S14, after winding of the yarn onto the winding package 13 has been completed, the yarn is cut off using the exchange cutting device 14, which results in loose yarn ends 31 on the winding package 13. In a next step S15, the loose yarn ends 31 are fixed with the second liquid 28 and / or the first liquid 27 using the yarn fixing application device 15.

[0091] After the loose yarn end 31 has been secured in the winding package 13 and the winding spindles 3.1; 3.2 have been braked accordingly, the finished winding package 13 can be removed in step 16. [Explanation of symbols]
