Definitions

  • the invention relates to a device for cooling a heated thread according to the preamble of claim 1.
  • a generic device is for example in the EP 0 403 098 A2 described.
  • a cooling body is provided with a cooling groove having a plurality of recessed Nuttaschen in the groove bottom of the cooling groove.
  • the cooling groove is coupled via a capillary with a coolant reservoir, so that a cooling liquid is kept continuously in the cooling groove.
  • the heated thread is guided by contact through the cooling groove and cooled by the cooling liquid. Subsequently, the thread is passed over a subsequent cooling rail.
  • the heat sink forms a relatively short cooling section, wherein the excess cooling liquid is collected at the end of the heat sink and returned to a tank.
  • texturing machines which consist of a plurality of such devices for cooling a heated thread, therefore facilities for collecting and processing the coolant liquid losses are required.
  • devices for cooling heated threads have not been able to prevail.
  • the preparation of the excess coolant is associated with a high expenditure on equipment.
  • the cooling groove has a plurality of guide portions with a grooved groove bottom and at least one guide portion with a smooth groove bottom, which are formed alternately one behind the other and that the metering one of the guide portions with grooved groove bottom in one Inlet region of the cooling groove is arranged upstream.
  • the invention has recognized that a corrugated groove bottom of the cooling groove considerably intensifies the wetting of the thread in the inlet region of the cooling groove.
  • a continuous looping of the yarn supplied to the cooling liquid is prevented by the corrugation in the groove bottom.
  • the corrugation in the groove base is suitable for stripping the adhering to the thread unevaporated coolant liquid residues and to keep in the cooling groove.
  • the thread can be evenly wetted over a longer distance, so that the generated cooling effects are intensified.
  • at least one guide section with a smooth groove base is provided, in which the thread is cooled by the previously supplied cooling liquid.
  • the different guide sections of the cooling groove therefore favor intensive cooling with minimal supply of cooling liquid.
  • the cooling effect within the cooling groove can be further improved by the guide section with the smooth groove bottom has a larger groove depth, as the guide sections with the corrugated groove bottom. This allows the thread to be guided through the cooling groove with and without contact. In the guide section with a smooth groove bottom, the thread receives no contact, so that only the cooling liquid acts to cool the thread.
  • the corrugated groove bottoms of the guide sections are each formed by a plurality of recessed groove pockets and a plurality of a plurality of guide webs lying between the nut pockets. The thread can thus pass through the cooling groove with contact on the guide webs.
  • the length of the cooling groove is generally selected depending on the respective thread to be cooled and its yarn denier. For example, threads with relatively large thread ends require relatively long cooling grooves.
  • the development of the invention is preferably carried out, in which the guide sections each have a longitudinal section of the cooling groove in the range from 10 mm to 60 mm.
  • the guide sections of the cooling groove in such a way that the groove bases in the thread running direction have a guide curvature with a radius in a range of 300 mm to 1000 mm ,
  • the groove bases in the thread running direction have a guide curvature with a radius in a range of 300 mm to 1000 mm .
  • the guide sections of the cooling groove can basically be formed in a one-piece heat sink.
  • the development of the invention is preferably carried out, in which the guide portions of the cooling groove are formed by a plurality of successively arranged segments of the heat sink, which are held by a carrier.
  • the composite segments thus provide the heat sink with the cooling groove required for the thread guide.
  • the development of the invention has proven particularly useful, in which the segments of the heat sink are formed with the guide portion with grooved groove bottom and the segments of the heat sink with the guide portion with smooth groove bottom of different materials.
  • the segments that are required for the thread contact in the cooling groove run with appropriate wear-resistant materials.
  • the inventive development of the invention is particularly advantageous in which the heat sink is disposed within a housing between a yarn inlet and a yarn outlet and formed in the region of the yarn outlet a suction opening on the housing, which is connectable to a suction device , This prevents any vapors from entering the environment when the thread cools.
  • the suction opening in a housing bottom between the heat sink and the yarn outlet.
  • the suction flow can be advantageously used to suck a freely guided thread section before exiting the housing.
  • the development of the invention is preferably carried out in which the thread inlet of the housing is assigned an inlet yarn guide and the yarn outlet of the housing an outlet yarn.
  • a reproducible thread guide can be set advantageously.
  • a special orientation of the heat sink within a textile machine is not required.
  • the device according to the invention is therefore particularly suitable for use in texturing machines with a large number of processing stations. Every processing point is an equal treatment and thus a uniform cooling by the device according to the invention executable.
  • FIGS. 1 . 2.1 and 2.2 a first embodiment of the inventive device for cooling a heated yarn is shown schematically in several views.
  • FIG. 1 shows the embodiment in a longitudinal sectional view and the Figures 2.1 and 2.2 Two cross-sectional views of the embodiment are shown. Unless an explicit reference is made to one of the figures, the following description applies to both figures.
  • the exemplary embodiment has an elongated heat sink 1.
  • the cooling groove 2 extends up to the front ends of the heat sink 1.
  • the cooling groove 2 thus forms a thread inlet 7 at the front ends and a thread outlet 8 at the opposite ends.
  • the cooling groove 2 has a plurality of guide sections 6.1 with a corrugated groove base 4.1 and a plurality of guide sections 6.2 with a smooth groove base 4.2.
  • the guide sections 6.1 and 6.2 are formed alternately in the direction of yarn travel in the cooling groove 2.
  • the thread inlet 7 is assigned a first guide section 6.1 with the corrugated groove bottom 4.1.
  • the ribbed groove bottom 4.1 of the first guide section 6.1 is preceded by a one-start region 20, in which a metering opening 3 opens.
  • the metering opening 3 is connected via a metering channel within the heat sink 1 with a fluid line 5.1.
  • the fluid line 5.1 is coupled to a metering device 5, which has a dosing 5.2 and a container 5.3.

  • the smooth groove bottom 4.2 has a groove depth, the in Figure 2.2 is designated by the reference symbol t 2 .
  • the groove depth t 2 of the smooth groove base 4.2 is made slightly larger than the groove depth t 1 of the corrugated groove base 4.1. Thus, t 1 > t 2
  • the guide sections 6.1 and 6.2 of the cooling groove 2 are arranged relative to one another such that the groove bases 4.1 and 4.2 form a guide curvature with a radius R in the thread running direction.
  • the radius R of the guide curvature is in the range of 300 mm to 1000 mm.
  • a cooling liquid is metered in small quantities fed to the guide section 6.1 in the region of the thread inlet 7 via the metering device 5. Due to the running thread, the cooling liquid is partly absorbed directly and distributed over the corrugated structure of the groove base 4.1. This achieves a relatively long contact zone for wetting the thread.
  • the guide section 6.1 has a longitudinal section L 1 which, depending on the thread titer, has a range of 20 mm to 60 mm.
  • the guide section 6.2 also has a longitudinal section of the cooling groove 2, which has an equal length depending on the thread titer.
  • the length section is in FIG. 1 denoted by the reference L 2 and is in the range of 10 mm to 60 mm.
  • the cooling groove 2 follows a contact zone with the corrugated groove bottom 4.1 and a non-contact zone with the smooth groove bottom 4.2 and another the thread outlet 8 associated guide section 6.1 with grooved groove bottom 4.1.
  • the middle guide section 6.1 with the corrugated groove base 4.1 removes the excess cooling fluid from the thread and at the same time leads to a homogenization of the wetting in order to obtain further cooling.
  • the thread is led out without substantially adhering excess coolant from the cooling groove 2.
  • the heat sink is usually encapsulated in a housing.
  • FIG. 3 a further embodiment of the inventive device for cooling a heated yarn in a longitudinal sectional view shown schematically.

  • Each of the segments 11.1 to 11.7 here forms a guide section 6.1 with a corrugated groove base 4.1 or a guide section 6.2 with a smooth groove base 4.2.
  • the guide sections 6.1 or 6.2 formed by the segments 11.1 to 11.7 are identical in their cross section to the exemplary embodiments according to FIGS. 2.1 and 2.2 executed. In that regard, a thread is guided with contact on the segments 11.1, 11.3, 11.5 and 11.7.
  • the segments 11.2, 11.4 and 11.6 have a smooth groove base 4.2, so that the thread is guided here without contact.
  • the heat sink 1 formed by the support 12 and the segments 11.1 to 11.7 is arranged inside a housing 13.
