Definitions

  • the present invention relates to a false-wire texturing machine in which the devices required for each texturing point, such as supply spool, delivery unit, texturing heater, cooling zone, swirl generator, take-off delivery unit, optionally SetHeizer and second take-off delivery unit and winding device have been arranged in a novel manner.
  • devices required for each texturing point such as supply spool, delivery unit, texturing heater, cooling zone, swirl generator, take-off delivery unit, optionally SetHeizer and second take-off delivery unit and winding device have been arranged in a novel manner.
  • the spatial arrangement of one texturing point is not to differ from the other, the individual texturing points with all the associated machine elements are inevitable; the length of the machine is determined by the absolutely necessary width of the machine parts, whereby usually the swirl generator driven by a flat belt determines the width of a texturing point, also called machine division.
  • the texturing heaters and any set or fixing heaters that may be present extend in a mirror image on both sides of the machine over the entire length of the machine. They therefore have very large heat-emitting surfaces. With the usual wall thickness of the thermal insulation, this leads to the unfortunate fact that only about 2 to 12% of the heating energy supplied is used to heat the thread, while the rest has to be destroyed by the air conditioning system which is usually present. According to the prior art, each machine has 2 gate parts that are relatively far apart and lead to long distances for the operating personnel. If several such texturing machines constructed in mirror image are arranged, there is also the risk of confusing the supply yarns, since the creel part of one machine then comes to rest next to the creel part of the next machine.
  • the texturing machine according to the invention for false wire texturing optionally under Simultaneous stretching of multifilament threads like the device according to the prior art, consists of a plurality of adjacent, similar sections, each of which has approximately 10 to 30 adjacent working positions.
  • this texturing machine is not a mirror image, it only has delivery units, texturing heaters and set heaters, which are each arranged in a row.
  • the texturing machine according to the invention is thus constructed asymmetrically with only one operating aisle and only one gate system.
  • Such an asymmetrically arranged texturing machine does not require more space than the previously known mirror-image devices, provided that the thread path of the threads in the individual working positions of a section can differ in angle and / or length from that of the neighboring position.
  • the thread courses of the working positions of a section converge from the first delivery unit to a compact texturing heater and diverge in the cooling zone from the texturing heater to the swirl generator.
  • the threads of a section can then preferably be passed through a common set heater.
  • a particularly narrow machine division does not result from the arrangement of the swirl encoders, as was previously the case, but spatially offset from one another in several rows.
  • the thread course of the individual working positions is not only defined in the texturing heater but also in the cooling zone or from the creel to the first delivery unit and from the first delivery unit to the texturing heater and through this heater and in the cooling zone by pipelines for the individual threads.
  • These pipelines can e.g. B. are stainless steel pipes with a small diameter. Pipes with an inner diameter of z. B. 6-10 mm, which are equipped at their ends, but possibly also at deflection points, with thread guide devices, for example made of sintered ceramic or the like.
  • pipelines for thread guidance can also be used in the later thread run. For example, this is the case for guiding the textured threads from the last delivery plant to winding them up under the work platform.
  • the device according to the invention has an asymmetrical structure, the gates 1 and 2 are combined side by side to form a gate system and the delivery mechanisms 3, 4 and 5 are only present once.
  • the swirl sensors 8 and 9 are arranged in two rows one below the other and spatially offset.
  • the device has only one working platform 10, from which all important parts of the device can be monitored and reached when the device is attached. This applies in particular to the first delivery unit 3, the swirl units 9 and 9, the second delivery unit 4 and the winding units 11-16.
  • the starting material e.g. B. multifilament threads 17 are drawn from stretch cops or as partially stretched thread material from spinning bobbins 18 overhead and guided via thread guide devices 19, 20 to the first delivery unit 3.
  • This delivery mechanism usually consists of a continuous shaft 21 and belt drives 22 which can be swiveled in.
  • a belt drive 22 which can be swiveled in separately is provided for each working position.
  • the threads 17 to be treated are then each guided in separate thread guiding devices. For the sake of clarity, only two of these thread guiding devices are shown in FIG. 1, they have the designations 23 and 24.
  • These thread guiding devices which preferably have the form of thin-walled tubes, then run through the texturing heater 6 and the further distance from the outlet of the texturing heater 6 to to the swirlers 8, 9, this latter distance representing the cooling zone for the threads 17 to be treated in the individual working positions.
  • the individual thread guiding devices are expediently provided with pipe connections which lead to suction. With the help of this known measure, it is possible to extract vapors occurring in the individual pipes as they run through the texturing heater 6.
  • These pipe connections 25, 26 usually have valves or flaps, which, for. B. with suction pistols can be closed. These switching elements are not shown in FIG. 1.
  • the actual Lichen swirler 8, 9 in two rows one above the other and laterally offset. In the embodiment according to FIG. 1, they are located above the head of the condition man standing on the platform 10.
  • Single or multi-disc friction swirlers are preferably provided as swirl transmitters, since only these devices have previously been able to maintain working speeds of 1,000 m / min or more.
  • the threads run from the twist sensors 8, 9 back to a common delivery unit 4, which has the same basic structure as the delivery unit 3 and then, if desired, through a set heater 7 and a further delivery unit 5 to the winding devices 11-16.
  • FIG. 1 A section at the point II -.- II through the texturing heater 6 is shown in FIG.
  • 18 thread guiding devices in the form of tubes are combined to form a tight bundle.
  • the tube bundle is surrounded by a heating chamber 27 which is closed off from the outside by the jacket 28.
  • the boiler room 27 can, for. B. be an empty room, which may be flowed through with diphyl vapor or another heating medium with condensation, but it can also contain electrical heating devices or the like.
  • a thermal insulation 29 is arranged, which is dimensioned so that the heat losses in the room are as small as possible.
  • this texturing heater is a device with an extremely small surface area. The heat transfer to the running threads is possible with the lowest heat loss and the lowest load on the room air conditioning system.
  • the course of the threads from the first delivery unit 3 to the texturing heater 6 is shown as a supervision for the section A-B according to FIG. 1 in FIG.
  • 18 working positions are included per machine section, i. that is, 18 threads 17 can be processed simultaneously.
  • the delivery mechanism 3 is shown with the continuous shaft 21 and with 18 belt drives 22.
  • the thread run to the heater 6 is passed through tubes which at the beginning have attachments made of sintered ceramic.
  • the tubes 23, 24 run in a star shape in the direction of the inlet to the texturing heater 6.
  • the individual tubes 23, 24 can run in one plane, as indicated in FIG. However, it is also conceivable that the tubes, in adaptation to the closely summarized course by the texturing heater 6, leave this level before the inlet.
  • the number of working positions per section is usually between 10 and 30 and depends essentially on design features such as.
  • a set of 3 winding devices one above the other are arranged on both sides of the operation.
  • a section consists of three such sentences next to each other, i.e. contains 18 working positions. If the winding devices are divided differently, different numbers of working positions per section are of course possible. It has been shown that the slanting of the threads to the heater as shown in Figure 3, and also the slanting from the heater 6 to the swirlers 8, 9 no impairment in the textile values and z.
  • B. the dyeability of the treated threads results when the number of individual thread guiding devices combined in the texturing heater 6 is limited to approximately 30.
  • FIG. 1 The course of the thread within the area CD according to FIG. 1 of the 18 working positions of a section is shown in FIG.
  • the tubes, which were combined to form a narrow bundle in the texturing heater 6, are pulled apart in a star shape in the cooling zone and lead to the twist generators 8, 9.
  • the numbers 23 and 24 which were selected in FIG. 1 to characterize the thread guiding devices were again chosen .
  • the swirl sensors 8, 9 are arranged in two planes, as can be seen from FIG. 1.
  • These swirlers e.g. B. uniaxial or triaxial friction swirlers generate the desired swirl, which runs in the running threads 17 through the cooling zone, the heater and the thread guide elements 23, 24 back to the feed unit 3.
  • the device according to the invention only has half the number of delivery units, i. H. if a set heater is used, only 3 continuous supply unit shafts are required, compared to 6 shafts of this type.
  • a further simplification of the device and, in particular, easier repairs and maintenance is possible if the three remaining supply unit shafts of supply units 3, 4 and 5 are driven by frequency-controlled individual motors will. In this case, the entire gearbox otherwise required is omitted.
  • Such a measure also leads to a significant reduction in the noise level.
  • the use of frequency-controlled single motors also enables the entire machine to be set using pre-programmed data carriers, for example by inserting a punch card.
  • a particularly simple design of the swirl drive is also achieved at this point by using frequency-controlled individual drives. This measure allows the machine division to be further reduced, i. H. So the space required per work position in a section.
