Definitions

  • the invention relates to a heating device for heating a running thread according to the preamble of claim 1.
  • the thread is guided at a distance from the surface by thread guides arranged at a distance from one another.
  • the fact that the thread guides are arranged on a convex curved line ensures that the thread abuts the thread guides and that the thread runs smoothly.
  • the thread is guided along a surface which has a temperature which is substantially above the target temperature of the thread.
  • the target temperature of the thread is the temperature to which the thread is to be heated.
  • the heating device is mainly used in false twist crimping machines for crimping synthetic threads.
  • the target temperature of the thread is in the range between 150 and 230 °.
  • the surface temperature is well above 300 °.
  • the object of the invention is to design the thread guide on the heating device according to the preamble of claim 1 so that the wrap angle on the thread guides and the total sum of the wrap angles on all thread guides can be freely selected without thereby also the distance of the thread path from the surface must be influenced.
  • the solution results from the characterizing part of claim 1.
  • the solution has the further advantage that the zigzag-shaped thread guide along the hot surface also extends the thread path or further shortens the length of the heater with the same length of stay of the thread on the heating surfaces .
  • the achievement of longer dwell times by zigzag-shaped guidance of fabric webs is known, e.g. from CA-PS 897 961.
  • CA-PS 897 961 is therefore not readily applicable to thread technology.
  • the thread guide along the radiator with changing spacing which is known from the St.dT, has the following disadvantage in particular:
  • the heat transfer between the heating element and the thread is dependent on the distance of the thread from the heating element.
  • this dependence is influenced by the temperature.
  • a different course of the distance between the thread and the radiator would therefore have to be set for each desired radiator temperature.
  • This disadvantage is avoided in the embodiment of the invention according to claim 2.
  • a precise setting of the distance of the thread running plane from the heating surface or heating plane of the radiator is achieved by the embodiment according to claim 3.
  • the heating surface is a level, in particular a flat plate.
  • the previously used curved heating rails can be dispensed with.
  • Favorable heat conduction can be achieved by the configuration according to claim 4.
  • a plurality of thread guides arranged one behind the other at a distance can be introduced into this groove.
  • the design of the groove and the thread guide results from claim 5 or 6.
  • Either the insert guides symmetrical to the central plane of the groove and the fork-shaped thread guide asymmetrical or the insert guides asymmetrical to the central plane of the groove and the thread guide can be constructed symmetrically. This results in an offset of the flanks of the fork-shaped thread guides guiding the thread relative to the central plane such that the thread is guided in a zigzag line penetrating the central plane.
  • the wrap angle on the individual thread guides and the sum of the wrap angles is of great importance for the quality of the textured thread.
  • a dimensioning rule is specified by claim 7 for the offset V between the thread guides.
  • the total length of the heating device can, however, be selected to be short in accordance with the lower heat requirement. Longer heating devices are required for synthetic threads in the titer range between 55 and 500 dtex, in particular polyester yarns and nylon medium-titer yarns.
  • the factor F is preferably between 0.8 and 0.15.
  • the total wrap angle is preferably greater than 7 ° and less than 40 °, preferably less than 30 °.
  • the design according to claim 8 serves this goal.
  • the heating device is composed of two or three radiators.
  • the bend angle between the individual radiators is small and can preferably be 1 ° to 10 °.
  • the embodiment according to claim 9 ensures good heat management and avoids heat loss.
  • the embodiment according to claim 10 facilitates thread insertion.
  • the fork-shaped thread guides form an open V on their open side - in the direction of view of the thread path - into which the thread can be inserted well.
  • the embodiment according to claim 11 ensures that the thread cannot climb out of the thread guides. This embodiment is particularly advantageous if the measure according to claim 8 is not used.
  • the radiator described so far can e.g. be made from a high-temperature steel. Because of the low manufacturing effort, a ceramic plate is also suitable (claim 12).
  • the embodiment of the invention according to claim 13 offers the advantage that the offset of the thread guides and thus the amplitude of the zigzag line can be adjusted at any time.
  • the tube can be closed and partially filled with a heat transfer fluid. The liquid will evaporate heated. This design ensures good temperature stability over the entire length of the radiator. Pressure control or temperature control of the heat transfer fluid can take place.
  • the heating device can be adapted to various process parameters, such as Thread speed, thread titer, desired target temperature, etc. adjust by simple maintenance work, without any intervention in the structure of the textile machine would be required.
  • Heating devices according to this invention are particularly suitable for heating the thread in the twisted zone of a false-wire texturing machine. It becomes possible to operate the false-wire texturing machine at high thread speeds with strong twisting and correspondingly strong crimping and to economically crimp even strong thread titers with good crimping.
  • the thread 7 is drawn off from the delivery spool 15 by the delivery mechanism 17 via thread guide 28.
  • the thread then passes to the heater 1, which consists of two pieces.
  • the first piece 19 is heated with the temperature T1.
  • the second part of the heater which is referred to as end piece 20, the thread is brought to the target temperature.
  • This end piece 20 is heated with a temperature T2.
  • a deflection thread guide 21 is provided behind the heater 1, via which the thread reaches the cooling rail 22 and the false twisting unit 23.
  • the thread is drawn out of the texturing zone by the delivery unit 24 and can then be guided via a second heater 25, deflection 26, delivery unit 27 for winding up with a bobbin 29, drive roller 30 and traverse 31.
  • the heating device consists of a heating element 1 on which thread guides 2 are arranged.
  • the thread guides 2 are webs which are arranged parallel to one another on the surface of the radiator 1.
  • the surface 3 forms the heating surface in the sense of this application.
  • the thread guides are in heat-conducting contact with the radiator 1.
  • the thread guides are arranged and dimensioned such that the thread is guided in a zigzag line over the heating surfaces 3 of the radiator. As a result, the thread comes into full contact with the thread guides.
  • Fig. 2 shows a schematic representation of the top view of a heating device in which a thread run in the form of a zigzag line is realized.
  • Thread guides 2 are screwed onto the radiator 1, which is heated in an analogous manner to that in FIG. 1.
  • the deflecting surfaces (heating surfaces) 35 of the thread guide 2 are arranged so that they deflect the thread 7 along a zigzag line 34, that is to say side-by-side and opposite deflecting surfaces mesh with one another and guide the thread so that it forms a zigzag line with the Thread guides 3 at the reversal points follows.
  • the length of the heater is shortened or shortened by the thread path along the zigzag line Length of stay of the thread on the heater increased.
  • the thread is fed to the first or last deflecting surface 34 by means of input and outlet thread guides 37.
  • the guiding of the thread in a zigzag line means that the thread is stretched in a surface and preferably in one plane (running surface or running plane). This running surface is at a distance from the surface 3 of the radiator 1 at all points of the thread run.
  • the thread guide 2, through which the zigzag line is spanned, have the most important feature, the deflection edge or deflection surface 35, which is shown and described in FIG. 2 and which penetrates the plane of the thread vertically.
  • the heating device consists of two individual radiator pieces 19, 20. These radiators are constructed essentially the same. The following description refers to both radiators. Every radiator is a cuboid, elongated body. In a longitudinal surface, two rectangular grooves are cut in the longitudinal direction and parallel to each other. The heating element is penetrated by a heating cartridge 10 in the center plane between the two grooves. It is a resistance heater. The resistance heater of each piece 19, 20 is connected to a regulator 18 - as shown and described in FIG. 1. In the grooves 8, 9 several thread guides are inserted with the same distance, namely in the first piece 19 four thread guides 2 and in the second piece 20 five thread guides 2. Each thread guide is located at the entrance and exit of each piece 19 or 20. Die Thread guides 2 are flat plates.
  • the grooves 8, 9 have insert guides for the thread guide 2, through which the thread guide 2 can be installed in planes transverse to the central plane 6.
  • the insert guides in the example shown are insert grooves 5 running around the walls, the width of which in the longitudinal direction essentially corresponds to the thickness of the thread guide plates.
  • cylindrical bores can also be made in the groove, the diameter of which corresponds to the width of the thread guide.
  • the depth of the insert grooves is symmetrical to the central plane 6 of the grooves. Therefore, the thread guides are constructed asymmetrically in their width. 5 for the grooves 8 and 9 differently designed thread guides are drawn. This is only used to describe various exemplary embodiments. In practice, one would probably only use one type of thread guide.
  • the thread guides shown on the right in FIG. 5 are each rectangular plates. In each of these plates, a slot 16 is made offset to the central plane 6. The slot extends parallel to the center plane 6 of the groove 9. However, it lies at a lateral distance from this center line. Successive thread guides 2 are each rotated about the central plane 6. Therefore, in the case of successive thread guides 2, the slot 16 alternately lies on one and the other side of the center plane 6.
  • the flanks of the slot 16 facing the center plane 6 each form the deflection surface 35 on which the thread is deflected in a zigzag shape.
  • the flanks of the slot 16 diverge in a V-shape on the open side of the slot.
  • the opening width of the V is so large that the flanks of successive thread guides 2 facing the central plane 6 intersect - in the direction of view of the thread path - and in turn form an alignment of V-shaped openings into which the thread can be inserted in a straight line.
  • the thread guides are again designed as flat, rectangular plates.
  • a slot is made in each of the plates from a broad side, asymmetrically to the center of the width.
  • the flank facing the center of the width or center plane 6 of the groove ends in a bulge 32 which at the same time forms the deflection surface 35.
  • the other side flank of the slot 16 runs more or less parallel to the central plane 6 of the groove.
  • the flank facing the central plane 6, penetrates the central plane 6 of the groove. It should be added that the bulge is laterally offset with respect to the central plane 6.
  • Successive thread guides 2 are each rotated about their axis during installation. For this reason, the bulges 32 of successive thread guides lie alternately on one and the other side of the central plane 6.
  • Each radiator 19, 20 is closed by a cover 13 and, moreover, each radiator is surrounded by suitable external insulation - which is not shown here. It is noteworthy that each groove 8, 9 is closed by its own cover. Therefore, only the affected groove needs to be opened for maintenance and operation.
  • the heating device consists of two pieces 19 and 20. As shown in FIG. 3, these radiators 19, 20 are bent at an angle alpha to one another. This measure is also sufficient when designing the thread guide slots 16 without climbing locks, that is to say as shown on the right in FIG. 5, in order to ensure a smooth thread run.
  • the angle alpha should be more than 1 ° and is preferably less than 10 °.
  • FIG. 6 shows a cross section through the heating device according to FIG. 5 on an enlarged scale.
  • the radiator 1 On a suitably beveled Carrier 36, the radiator 1 is screwed to the heaters 2 attached to it.
  • the heater 1 is designed with a cavity 8 and a heating cartridge similar to that in FIGS. 1 to 3 and arranged in an insulating box 12 with a cover 13.
  • the heating surface is formed in the heating element 2 as a V-shaped groove, which is off-center and into which the thread 7 can be inserted when the cover 13 is open.
  • the successive heating pieces 2 In the longitudinal direction of the heater 1, the successive heating pieces 2 can be arranged so that the thread 7 follows a zigzag line corresponding to FIG. 5.
