Description

Method and device for producing a grass yarn

The invention relates to a method for producing a grass yarn for use of artificial turf according to the preamble of claim 1 and to an apparatus for producing a grass yarn according to the preamble of claim 10.

In the production of artificial turf so-called grass yarns are used which have a composite of several monofilaments or foil tapes. For this purpose, the grass yarn is preferably processed in a tufting process to an artificial grass carpet. For this it is necessary that the monofilaments or film tapes have sufficient cohesion within the grass yarn.

For example, EP 0 648 868 A1 discloses a process for producing grass yarns in which the monofilaments are first produced in an extrusion process. The grass yarn is then formed by twisting several monofilaments. In the known method, the cohesion of the fiber bundle is achieved by a rotation of several monofilaments, but also lost the desired for an artificial grass band-like structure of the monofilaments and is helical. In addition, a sufficient cohesion of the fiber bundle for the further treatment can only be achieved by a very intensive twisting of the individual monofilaments.

By contrast, EP 1 728 902 discloses a method in which the grass yarn is produced in a process. For this purpose, the composite of filaments after extrusion and drawing is produced by stuffer box crimping. Following this, the grass yarn is wound into a spool. In principle, however, this process also has the disadvantage that kinking of the monofilaments produces kinks in the monofilaments which have a very negative influence on the setting up behavior of the monofilaments in a pile. In addition, a slight cohesion between the individual monofilaments is achieved by the crimping of the monofilaments, which are usually produced in the form of strips.

It is an object of the invention to develop a method for producing a grass yarn for use in artificial turf and a device for producing a grass yarn of the generic type such that the extruded monofilaments or film tapes can be brought together before winding to a safe fiber bundle.

This object is achieved for a method according to the invention in that the fiber bundle is wrapped before winding with a composite thread and that the fiber bundle is wound together with the composite thread to form a coil.

For a device, the object is achieved in that the winding device is preceded by a Umwindeeinrichtung in the yarn path through which a fiber bundle formed from a plurality Monofϊlamenten or film tapes with a composite thread is wrapped.

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

The invention is based on the reservation to combine a discontinuous wrapping process with a continuous extrusion process. For example, from DE 102 60 121 Al a Umwindeprozess is known in which the composite thread is removed from a supply spool. Thus are continuous process interruptions and bobbin replacement are required to complete the wrapping process.

The invention now opposes these reservations and surrounds the fiber bundle formed continuously from a plurality of monofilaments or foil strips immediately before the fiber bundle is wound up.

In order to obtain as few interruptions as possible due to a change of supply bobbin of the composite yarn, the process variant is used with particular preference, in which the composite yarn continuously withdrawn from the supply bobbin and wound around the fiber bundle with a few turns in the range 20 to 70 turns per meter of fiber length , Thus, on the one hand, sufficient cohesion of the monofilaments or film strips within the grass yarn can be produced and, on the other hand, relatively long run times of the supply bobbins can be achieved.

The development of the device according to the invention provides for this purpose a coupled with a controllable drive hollow spindle with a arranged on the circumference of the hollow spindle bobbin holder for receiving the supply spool, wherein the hollow spindle is assigned to an inlet end an inlet yarn guide and at an outlet end an outlet yarn guide for guiding the fiber bundle , Thus, by rotation of the hollow spindle and the bobbin holder in the wrapping device, the desired number of turns per fiber length can be set as a function of the feeding speed of the fiber bundle.

In order to produce a uniform winding of the fiber bundle, the method variant is particularly advantageous, in which the fiber bundle is supplied without slip for the purpose of winding at constant speed and constant yarn tension. The separation and feeding by a godet unit has the particular advantage that the fiber bundle, regardless of the upstream process steps, preferably always on a family of monofilaments or foil tapes can be directed to the Umwindungsprozess under constant conditions. In this case, even different guide lengths in front of the godet unit can advantageously be compensated for voltage differences.

In addition, in order not to obtain any interactions between the upstream treatment steps, such as stretching or relaxing of the monofilaments or foil tapes, the fiber bundle is preferably fed by a driven godet and a filler roll, which are looped around several times by the fiber bundle. This avoids fluctuations in the tension on the fiber bundle during winding. The godet unit is associated with a driven godet and a Beilaufrolle the Umwinde directly on an inlet side.

In order to be able to provide as much as possible of the composite thread within a supply spool, the composite thread is preferably formed from a crimped multifilament thread, which is produced in a melt spinning process from a colored polymer melt and textured in a subsequent process. In addition, the crimped multifilament yarn provides a secure hold and sufficient elasticity to hold the monofϊ parliamente within the grass yarn during further processing.

By a green coloring of the polymer melt for the production of the composite thread and for the production of the Monofϊlamente or film tapes, a color required for the artificial turf can be achieved. The composite thread thus does not appear in the artificial turf.

According to a further advantageous development of the method, the wound fiber bundle is pulled off directly by a winding spindle driven for winding and wound with a winding speed in the range of 50 to 500 m / min to the coil.

- A - During threading, the thread tension is kept at a constant winding level essentially via a dancer arm control of the winding spindle.

In the production of monofilaments, it is common for them to be simultaneously extruded, cooled and drawn in a wide variety. In that regard, the method variant is preferably used, in which the crowd of Monofilamen- te is divided after stretching into a plurality of fiber bundles and the fiber bundles are separated before winding. This allows a plurality of fiber bundles to be wrapped in parallel and wound up into coils.

Alternatively, however, it is also possible to extrude a sheet of a thermoplastic material and cool. The film can then be divided into a crowd of film strips, so as to be able to form a large variety of fiber bundles.

The development of the device according to the invention, in which the Umwindeeinrichtung upstream of a feed side a Fadenabsaugeinrichtung, allows a change of the supply bobbin in the wrapping without the extrusion process of the monofilaments or film strips is interrupted. During the change of the supply spool, the continuous monofilaments or film strips are picked up by the suction device and led to a waste container.

In this case, after the expiry of a feed bobbin, it is advantageously possible to avoid the missing winding of the fiber bundle by monitoring the supplied composite yarn with a sensor. In the event that the sensor signals a thread break or a missing composite thread, the winding process can be interrupted directly and the monofilaments or film strips or the fiber bundle is severed and taken over by the upstream suction device. In order to wrap and coil a multiplicity of fiber bundles parallel next to one another and wind up, according to an advantageous development of the device according to the invention, the wrapping device is formed by a plurality of separate wrapping stations to which several separate winding stations of the winding device are assigned, each winding station being assigned a separate galette unit. This makes it possible to produce a large amount of grass yarn in an extrusion process. By the godet units, a separation of the plurality of fiber bundles is possible, wherein the number of fiber bundles is equal to the number of godet units.

This arrangement is particularly suitable for drawing the fiber bundles directly from a common godet delivery unit, which serves, for example, for drawing a crowd of monofilaments or foil tapes. The different lengths of guide tracks that arise between the wrapping stations and the godet delivery unit remain without any influence on the wrapping process.

The method according to the invention and the device according to the invention will be described in more detail below with reference to an exemplary embodiment of the device according to the invention.

In Fig. 1, the embodiment in an overall view, in Fig. 2 in a plan view of the wrapping device and winding device and in Fig. 3 in a partial view of the Umwindungsstationen and Aufspulstationen shown schematically. The following description applies to all figures, insofar as no explicit reference is made to one of the figures.

In Fig. 1, the embodiment of the device according to the invention is shown in an overall view. The exemplary embodiment has a melt spinning device 1 in order to extrude a thermoplastic material into a multiplicity of monofilaments. For this purpose, the melt spinning device 1 has an extruder 2 and a spinner head 3 connected to the extruder 2.

The melt spinning device 1 is associated with a cooling device 4. The cooling device 4 is formed in this embodiment by a cooling bath 5, which is assigned directly to the spinning head 3 of the melt spinning device 1.

To deduct and stretch the monofilaments several godets 7.1 and 7.2 are arranged one behind the other. The godet delivery 7.1 and 7.2 have a plurality of driven godets 8, on the circumference of the monofilaments 6 are guided in parallel run side by side with simple wrap.

Between the cooling device 4 and the first godet delivery 7.1 a plurality of deflection rollers 9 are provided, at the periphery of the monofilaments 6 are guided with simple wrap. The deflection rollers 9 are arranged downstream of the cooling device 4 in order to strip off the cooling liquid of the cooling bath 5 adhering to the monofilaments 6. Between the Godet 7.1 and 7.2 a heater 10 is arranged. The heater 10 is in This exemplary embodiment is formed by a convection oven 40, in which the monofilaments 6 are heated to a draw temperature. To stretch the monofilaments, the godets 8 of the godet delivery units 7.1 and 7.2 are driven at a speed difference.

After stretching, the monofilaments 6 are combined in groups into fiber bundles and fed to a wrapping device 13 and a winding device 14. One wrapping station and one winding station are provided per fiber bundle, wherein the wrapping stations and the winding stations are formed together on a frame wall 39. Thus, a first fiber bundle 12.1 is fed to a first winding station 13.1 and then wound up by the winding station 14.1 into a coil. Accordingly, the fiber bundle 12.2 a second Umwindungsstation 13.2 and a second Aufspulstation 14.2 assigned, etc.

In Fig. 2 is a plan view of the wrapping device 13 and winding device 14 is shown, wherein the monofilaments 6 are divided into a total of five fiber bundles 12.1 to 12.5. Each fiber bundle 12.1 to 12.5 contains five monofilaments in this embodiment. The monofilaments 6 are performed at the end of the last godet 8 of the godet delivery 7.2 on the guide rail 11 and divided into the fiber bundles 12.1 to 12.5. The fiber bundles 12.1 to 12.5 are separated and wound in the wrapping device 13 each with a composite thread and then wound in a winding device 14 to form a coil. For this purpose, the wrapping device 13 has a total of five wrapping stations 13.1 to 13.5. The winding stations 13.1 to 13.5 are each followed by a winding station 14.1 to 14.5 of the winding device 14. The winding stations 13.1 to 13.5 and the winding stations 14.1 to 14.5 are arranged side by side on a frame wall 39.

For further explanation of the wrapping device 13 and of the winding device 14, FIG. 3 shows a view of the first wrapping station 13.1 and the first winding station 13.1. 10 winding station 14.1 shown schematically in a view. The Umwin- ding stations 13.1 to 13.5 and the Aufspulstationen 14.1 to 14.5 are identical, so that only the Umwindestation 13.1 and Aufspulstation 14.11 will be described below.

The Umwindungsstation 13.1 of the Umwindungseinrichtung 13 has a hollow spindle 18 which carries a coil holder 19 on the circumference. On the coil holder 19, a feed coil 20 is arranged. The hollow spindle 18 is coupled to a spindle drive 23, which drives the hollow spindle 18 and the coil holder 19 with the supply spool 20 to rotate. At a lower inlet end, the hollow spindle 18 is associated with an inlet yarn guide 27 and at an outlet end with an outlet yarn guide 30. The inlet yarn guide 27 and the outlet yarn guide 30 guide the fiber bundle 12. 1 through the hollow spindle 18.

On the outlet side of the hollow spindle 18, a composite thread 21 drawn off from the supply bobbin 20 is fed into the fiber bundle 12.1 and continuously wound around the fiber bundle 12.1 by rotation of the supply bobbin 20 through the hollow spindle 18 and the bobbin holder 19.

On the inlet side of the hollow spindle 18, a godet unit 15 is provided, which is formed from a driven godet 15.1 and a freely rotatable Beilaufrolle 15.2. The godet 15.1 is driven by a godet motor 15.3, which is arranged on the back of the frame wall 39 (see Fig. 2).

Between the godet unit 15 and the Umwindungsstation 13.1 a Fadenabsaugeinrichtung 16 is arranged. The Fadenabsaugeinrichtung 16 contains not shown here means for separating and sucking the fiber bundle 12.1. The Fadenabsaugeinrichtung 16 can be activated via a control device not shown here, which is connected to a sensor device 22. The sensor device 22 is arranged on the outlet side of the hollow spindle 18 and monitors the inlet of the composite thread 21 to the fiber bundle 12.1. For In the event that the supply spool 20 is completely removed, the absence of the composite yarn 21 is detected via the sensor device 22 and reported to the control device. Thereupon, the thread extraction device 16 can be activated, so that the continuously supplied fiber bundle 12.1 can be sucked off and guided to a waste container.

On the discharge side of the Umwindestation 13.1 the winding station 14.1 is arranged. The winding station 14.1 has a coil carrier 32, which is coupled to a coil drive 34. At the bobbin 32, a coil 33 is gewek disgusted. The bobbin 32 is assigned a pressure roller 37 and a traversing device 36 in the yarn path. For this purpose, the pressure roller 37 is held on a movable roller carrier 41 and contacts the wound coil 33 with contact.

In the yarn path of the traversing device 36 is assigned a Tänzerarmregeleinrichtung 35, which supplies the fiber bundle 12.1 via a loop between two yarn guides 38.2 and 38.3. The Tänzerarmregeleinrichtung 35 is coupled to the coil drive 34, so that the fiber bundle 12.1 is wound with substantially constant Aufwickelspannung to the coil 33.

In this embodiment, the bobbin 32 is formed by a winding spindle, on the circumference of a sleeve for receiving the coil 33 is tensioned. In principle, however, it is also possible to form the coil carrier 32 by clamping plates, which hold a winding tube between them.

In order to guide the fiber bundle 12.1 through the hollow spindle 18 at the beginning of the process or after a change of the supply bobbin 20 in the winding station 13, an injector device 24 is provided on the inlet side of the hollow spindle 18, which generates an air flow for sucking and threading the fiber bundle. In this case, the inlet yarn guide 27 is designed to be pivotable, so that the fiber bundle via a manually guided suction gun directly to the through Injector 24 formed suction opening can be kept. For this purpose, the inlet yarn guide 27 can be pivoted laterally into a contact position adjacent to the hollow spindle 18. The application position of the inlet yarn guide 27 is shown in dashed lines.

On the outlet side of the hollow spindle 18, a suction nozzle 31 is arranged, which is held in axial extension to the hollow spindle 18. At the suction nozzle 31, a suction flow can be generated, which receives the end of the fiber bundle 12.1 threaded through on the outlet side of the hollow spindle 18. Thus, the fiber bundle 12.1 in the section between the hollow spindle 18 and the suction nozzle 31 can again take over a manual suction gun and insert in the subsequent take-up device.

In the embodiments illustrated in FIGS. 1 to 3, a grass yarn is produced, which is used in a further processing process for producing an artificial turf. For this purpose, a thermoplastic material in the form of granules of, for example, PP or LLDPE or HDPE or PA is fed to the extruder. In the extruder, the material is extruded to a preferably colored polymer melt. The polymer melt could thus obtain a green color, which is produced either by additives or by colored granules. The polymer melt is extruded via the spinning head 3 into a plurality of monofilaments 6. The monofilaments 6 occur after the extrusion for cooling in the cooling bath 5. The monofilaments 6 are withdrawn together by a first godet delivery 7.1 with several godets 8. To strip off the remaining cooling liquid, the monofilaments 6 are guided over a plurality of deflection rollers 9.

For stretching between the godet supplies 7.1 and 7.2, the monofilaments 6 are heated in the heater 10 to a stretching temperature. In this embodiment, the heating is carried out by a hot air of the Um- However, there is also the possibility of carrying out the heating of monofϊ parliament 6 by means of hot water.

After stretching, the Monofϊlamente 6 are merged into several fiber bundles 12.1 to 12.5. In this embodiment, five mono filaments are combined to form a fiber bundle. Each of the fiber bundles 12.1 and 12.5 is removed separately by a respective godet unit 15 from the last godet 8 of the godet delivery unit 7.2. The godet units 15 are directly associated with the Umwindestationen 13.1 to 13.5, so that each of the fiber bundles are guided on different lengths of guidance between the godet units 15th and the last godet 8. The godet units 15 are driven independently of each other, so that each of the fiber bundles under constant conditions the respective Umwindestationen can be fed.

In order to obtain a cohesion of the individual mono filaments in the respective fiber bundles 12.1 to 12.5, each of the fiber bundles 12.1 to 12.5 in the wrapping device 13 is wrapped with a composite thread 21. For this purpose, the composite thread 21 is drawn off continuously from a supply spool 20 and wound around one of the fiber bundles 12.1 to 12.5 with approximately 20 to 70 turns per meter of fiber length. The supply of the fiber bundle to the respective Umwindungsstation takes place at a constant speed, which is determined by the godet unit 15. By a multiple wrapping of the fiber bundle around the godet unit 15, the fiber bundle is guided substantially without slip, so that possible thread tension fluctuations in the upstream process steps without affecting the Umwindevorgang remain.

As composite yarn 21, a crimped multifilament yarn is preferably used, which was produced in a melt-spinning process from a colored polymer melt and was textured in a subsequent process. Such crimped multi-filament yarns have a grip and residual elasticity which provides a secure hold and bond of the mono filaments within the fiber bundle form. In this case, the composite thread 21 is preferably likewise produced with a green coloring, so that the fine multifilament yarn adapts to the color of the fiber bundle and does not appear in subsequent processing processes, and in particular in artificial turf.

It should be noted, however, that depending on the application and yarn type, non-crimped composite yarns, non-dyed composite yarns or monofilament composite yarns could be used to wind up.

After the fiber bundle has been wound, it is wound up directly in the winding station into a coil 33. The withdrawal of the fiber bundle from the wrapping station thus takes place directly through the driven bobbin 32. The bobbin is driven at a winding speed in the range of 50 to 500 m / min. The respectively set winding speed of the spool carrier 32 is kept constant by the dancer arm control 35 during the entire winding cycle. The fiber bundle is wound as a grass yarn to the coil 33 and can be processed directly in a follow-up process, for example in a tufting process to an artificial turf. The bond between the monofilaments within the fiber bundle is ensured by the composite thread 21.

In the illustrated embodiment, the family of monofilaments is divided into a total of five fiber bundles. The number of fiber bundles and the number of monofϊ parliamentes forming a fiber bundle is exemplary. In principle, a multiplicity of fiber bundles can be produced simultaneously with such a device and with such a method. After separating the fiber bundles, each of the fiber bundles is wrapped in a separate winding station with a composite thread and then wound in a winding station to form a coil. In that regard, can be arranged side by side on a rack wall, a plurality of Umwindungsstationen and Aufspulstationen. Furthermore, the illustrated and described treatment steps for the treatment of the monofilaments and the fiber bundle are exemplary. In principle, additional treatment steps for the treatment of the monofilaments, for example a relaxation treatment between further godet delivery devices or further treatment steps for the treatment of the fiber bundle, may be provided. Thus, in principle, it is possible to supply the fiber bundles to a crimping process before winding and winding.

The exemplary embodiment of the device according to the invention shown in FIG. 1 can alternatively also be carried out with a melt spinning device for extruding a film in order to form the plurality of fiber bundles from a group of foil strips. In this case, the spinning head shown in Fig. 1 would extrude a flat sheet of a thermoplastic material. The film would be cooled in the cooling bath and, after being withdrawn from the cooling bath, split into a crowd of film strips. The embodiment in Fig. 1 would then be supplemented for example by a cutting device which could be arranged between the pulleys and the godet delivery. The remaining devices of the embodiment according to FIG. 1 remained completely identical, so that no further explanation of this alternative is required and reference can be made to the aforementioned description. Instead of the monofilaments then the film strips would be performed.

The method according to the invention and the device according to the invention have the particular advantage that a grass yarn which can be used for the production of artificial turf can be produced directly in the extrusion process. There are no further intermediate processes that require rewinding necessary. The coils with the wound grass yarn can be submitted directly to a tufting process. LIST OF REFERENCE NUMBERS
