Definitions
- the invention relates to a texturing machine for false twist texturing of a thread according to the preamble of claim 1.
- a generic texturing machine is known from EP 0 853 150.
- a supplied plain yarn is textured by a false twist process.
- the false twist generated by a false twist unit is fixed in the thread by a heat treatment and a subsequent cooling.
- a cooling tube is used, on the surface of which the thread is helically guided.
- the known texturing machine has movable thread guides which change the point at which the thread runs up or down relative to the circumference of the cooling tube.
- changing the thread guide basically has the disadvantage that the treatment devices upstream or downstream in the thread path must be included in the changed thread guide.
- the cooling tube is designed to be movable, so that the length of the cooling section on the circumference of the cooling tube can be changed by a movement of the cooling tube.
- This makes it possible to adapt the thread guides to the special conditions of pre-treatment or post-treatment. In particular, this allows stronger deflections on the thread both when entering and leaving the cooling device. Avoid tion as well as within the cooling device.
- the cooling tube can be adjusted by rotating, swiveling or tumbling movements, so that the thread guided on the circumference can be guided with more or less looping.
- the cooling tube is held by an adjustable holding device, by means of which the relative position between the outlet end and the inlet end of the cooling tube can be changed.
- one of the ends of the cooling tube can be kept essentially unchanged in position, which particularly simplifies the connection of a cooling fluid supply.
- the movements required for changing the length of the cooling section are thus carried out essentially with the end of the cooling tube not connected to the cooling fluid supply.
- the holding device is equipped with a guide means through which the drain end of the tube can be guided and locked relative to the drain thread guide.
- the cooling pipe could be moved in a simple manner by pivoting the drain end relative to the drain thread guide.
- the drain thread guide is attached to the circumference of the cooling tube.
- the cooling pipe is guided through the guide means by rotation about the drain thread guide, which acts as a fulcrum.
- the movement of the cooling tube required for changing the length can also advantageously be formed by the inlet end of the cooling tube according to the developments according to claims 6 and 7.
- the movement of the cooling tube is preferably carried out by an actuator so that the length of the cooling path has the same setting in each processing point.
- the inlet thread guide and the outlet thread guide or only one of the thread guides can be designed to be adjustable.
- FIG. 1 shows a schematic structure of a texturing machine according to the invention
- FIG. 2 shows different views of the cooling device of the texturing machine from FIG. 1;
- Fig. 3 shows schematic views of another embodiment of the
- a processing point contains at least a first delivery mechanism 5, a heating device 6, a kuM device 7, a false twist unit 16, a second delivery mechanism 15 and a winding device 17, the process units being arranged one behind the other to form a thread path.
- a thread 1 is drawn from a supply spool 2 by the first delivery unit 5.
- the supply spool 2 is attached to a mandrel 3 of a gate (not shown here).
- the first Lie 1 ferwerk 5 guides the yarn 1 in the so-called false twist zone extending up to the. False twist assembly 16 extends.
- False twist assembly 16 extends.
- a false twist is generated in the 'yarn 1 running back within the false twist zone in the thread and is thereby fixed in the heater 6 and the subsequent cooling device.
- the thread is drawn off from the false twist unit 16 by the second delivery mechanism 15 and fed to the winding device 17. In the winding device 17, the thread 1 is wound into a bobbin 18.
- the cooling device 7 In order to cool the thread 1 within the false twist zone, the cooling device 7 consists of a cooling tube 8, which is connected via a line 10 to a coolant source 9.
- the cooling tube 8 is assigned an inlet thread guide 19 at one end, which guides the thread 1 to the cooling tube 8, and an outlet thread guide 20 at the opposite end.
- the end of the cooling tube 8 in the area of the inlet thread guide 19 is referred to here as the end 21 and the opposite end of the cooling tube 8 as the end 22.
- the coolant is supplied via the run-up end 21, which is connected to the coolant source 9 through the line 10.
- the inlet thread guide 19 and the drain thread guide 20 are attached separately from the cooling tube 8 in a fixed position on a machine frame, not shown here.
- the cooling tube 8 is held by the holding device 11 between the inlet thread guide 19 and the drain thread guide 20.
- the holding device 11 has a holder 12 in the region of the outlet end 21 and a guide means 13 in the region of the outlet end 22.
- the cooling tube 8 is held in the holding device 11 in such a way that the thread 1 is guided helically on the circumference of the cooling tube 8 from the run-up end 21 to the drain end 22.
- the degree of wrap or the pitch angle of the helix on the circumference of the cooling tube 8 determines the length of the cooling path in which there is contact between the thread 1 and the cooling tube 8. At constant thread speed; becomes a cooling effect determined by the length of the cooling section. Thread .1 produces.
- the cooling tube 8 can be released from a fixation in the holding device 11 and moved in such a way that the length of the cooling section becomes larger or smaller, ie the looping of the thread is increased on the circumference of the cooling tube 8 or vice versa, the holding device 11 and the cooling tube 8 are shown schematically in different views in Fig. 2.
- a top view is shown in Fig. 2.1
- a front view is shown in Fig. 2.2
- Components of the cooling tube 8 and the holding device 11 are shown, insofar as no express reference is made to one of the figures, the following description applies to both figures.
- the leading end 21 of the cooling tube 8 is held movably in the holder 12.
- the outlet end 22 of the cooling tube 8 is held in the guide means 13.
- the guide means 13 is formed with a holder 25 which receives the cooling tube 8.
- the holder 25 has a circular guide contour 26.
- the guide means 13 is aligned with the guide contour 26 to the drain thread guide 20 such that the drain thread guide 20 is aligned eccentrically to the guide contour 26.
- the position of the drain thread guide 20 always remains the same.
- the Cooling tube 8 can thus be turned conically around the drain thread guide 20.
- a plurality of fixing means 14 are provided on the guide means 13, by means of which the drain end 22 of the cooling tube 8 can be held in any position within the holder 25 on the guide contour 26.
- the cooling tube is shown in dashed lines in a second position with a larger thread wrap and thus a longer cooling section.
- the drain end 22 is brought around the drain thread guide 20 in the holding device 11.
- the opposite overflow end 21 of the cooling tube remains essentially unchanged in its position.
- the evasive movements are absorbed by the holder 12, *.
- the design of the holding device and in particular the design of the guide means 13 is exemplary.
- FIG. 3 shows a further exemplary embodiment of a cooling device 7.
- the kublrohr 8 is releasably held in the holding device 11.
- the drain thread guide 20 is attached at the drain end 22 to the circumference of the cooling tube 8.
- the inlet thread guide 19 is held stationary on a machine frame.
- the guide means 13 has a circular cutout 27 with a circular guide contour 26. Inside the cutout 27, the cooling tube 8 is arranged such that the drain thread guide 20 is aligned eccentrically to the guide contour 26.
- the cooling tube 8 is rotated about the drain thread guide 20, which acts as a fulcrum, until a desired position or a predetermined length of the cooling section is reached.
- the rotational movement of the cooling tube 8 is carried out within an imaginary envelope 24.
- the envelope curve 24 is conical, the cone tip of which is formed by a thread guide 23 at the outlet of the heating device 6. It is thereby achieved that the deflection at the run-up end 21 of the cooling tube 8 is small relative to the inlet thread guide 19, so that a tangential run-up of the thread on the circumference of the cooling tube 8 remains guaranteed.
- the cooling tube is fixed.
- the fixing means are not shown in Figure 3.
- the invention extends beyond the illustrated exemplary embodiments. So it is possible to carry out the movement of the cooling tube essentially with the inlet end. The end of the expiration would be kept essentially unchanged in the position. Likewise, the movement of the cooling tube could be controlled by actuators which, for example, move directly to a preselected position and hold the cooling tube in the approached position.
- the wrapping of the thread on the circumference of the cooling tube achieved by the adjustment of the cooling tube according to the invention is essentially in the range of 0 ° and 360 °. However, wrapping> 360 ° could be achieved in particular with the embodiment shown in FIG. 3.
