The invention relates to an entanglement device for entangling synthetic multifilament yarns by means of a pre-pressurized working medium fluid, wherein the entanglement device has a yarn treatment channel which is configured for the transport through and entanglement of the multifilament yarns, wherein the yarn treatment channel is defined by a wall having nozzle walls in which nozzle through-openings for the supply of the pre-pressurized fluid working medium are formed and baffle walls to which the working medium is distributed, wherein in the wall defining the yarn treatment channel there are arranged discharge means through which the used working medium and/or entrained air can be discharged.
Description
Technical Field
The invention relates to an entangling device (entangling device) for entangling a synthetic multifilament yarn by means of a fluid-like pre-pressurized working medium.
Background
Entanglement devices are known from the prior art.
DE102008018079a1, for example, discloses a device for entangling multifilament yarns, in which a pre-pressurized working medium, such as, for example, compressed air, is supplied via nozzle through-openings into a yarn treatment channel to induce the multifilament yarns guided therein to interlace and form intertwining knots of their filaments forming the multifilament yarns.
A disadvantage of this entangling device is that the supplied and used pre-pressurized compressed air may escape from the yarn treatment channel only by the input opening through which the yarn enters the yarn treatment channel or by the output opening through which the yarn of the entangling device leaves the yarn treatment channel, which may counteract the filament entangling process to form intertwined knots.
Disclosure of Invention
The object of the invention is therefore to provide an entanglement unit where the compressed air supplied and used for entanglement does not adversely affect entanglement knot formation.
According to the invention, this object is achieved by a twisting device.
The entanglement device according to the invention allows a more active discharge of the supplied pre-pressurized fluid working medium, for example pre-pressurized compressed air, without the used (used) fluid working medium or the used compressed air or air entrained by the yarn as it is guided through the yarn treatment channel adversely affecting the kink formation.
With the entangling apparatus of the invention, the diverted compressed air at the baffle is not blocked by the already existing compressed air used and thereby prevents entanglement formation. Otherwise, the compressed air used must escape at the input and output of the entangling apparatus, which may interfere with and disturb the entangling process.
With the entangling apparatus of the invention additional deflection and drainage possibilities are provided for the used fluid working medium or the used compressed air stream, so that e.g. a retardation loss of the used working medium generating the stream does not affect the efficiency of the entangling apparatus. The working medium shall here mean a supply of compressed air which has for example entangled the multifilament yarn.
Since the efficiency of the entangling apparatus is increased by means of the discharge device, compressed air which is less pre-pressurized is advantageously required, since there is substantially no need to exert a counter force on the amount of compressed air used. This results overall in less compressed air consumption, whereby compressed air production requires little energy, which can be saved.
According to an exemplary embodiment of the entanglement unit, the discharge device (displacing device) is arranged substantially transversely, obliquely, parallel and/or perpendicularly with respect to the course of the nozzle through-opening and is laterally delimited on both sides by wall portions in the direction of extension of the yarn treatment channel. Double-sided delimitation of the discharge device shall mean that the discharge device forms through-openings in the wall defining the yarn treatment channel, which through-openings are brought into fluid contact only in the direction towards the yarn treatment channel, in particular transversely to the yarn guiding direction. In addition, the discharge device is surrounded by the wall of the yarn treatment channel and is arranged at a distance from the yarn insertion gap, which merely has the function of inserting the yarn into the entanglement device. This has the advantage that the working medium used can be better guided out of the entanglement zone of the yarn treatment channel and that the working medium used does not hinder the entanglement process of the multifilament yarns.
According to an exemplary embodiment of the entangling apparatus the discharge means are arranged adjacent, adjacent and/or at a predetermined distance with respect to the nozzle through-opening. Depending on the positioning of the discharge device relative to the nozzle through-opening, it is possible to actively or passively control when and when a small amount of the used working medium should be discharged.
According to an exemplary embodiment of the entanglement unit, the discharge device is arranged in a wall of the yarn treatment channel, which is arranged opposite, in or remote from the wall, said wall corresponding to a nozzle wall and/or a baffle wall (barrier wall). For optimum discharge, the discharge device can be arranged in the wall of the yarn processing channel of the entangling device at a predetermined optimum position. The disturbances and slugging flow conditions caused by the discharge means can then be eliminated to obtain and maintain optimum entanglement of the multifilament yarns.
According to an exemplary embodiment of the entangling apparatus the discharge device has a discharge through-opening having a discharge inlet and a discharge outlet, wherein the discharge inlet and the discharge outlet are arranged relative to each other such that the discharge inlet and the discharge outlet are concentric with each other, eccentric to each other and/or laterally offset from each other. Since the outlet inlet and outlet openings are arranged concentrically, eccentrically or offset laterally, respectively, an undesired return flow of the working medium into the thread treatment channel can be prevented. The discharge outlet may also be defined by additional attachment to the entangling apparatus, wherein appropriate elbows and discharge lines may be provided.
According to an exemplary embodiment of the entanglement unit, the discharge inlet is located at the same level as, above and/or below the nozzle through-opening and/or at the same level as, above and/or below the yarn guide zone of the yarn processing channel.
Since the discharge inlets are arranged at the same or different level with respect to the nozzle through-openings and/or the yarn guiding zone and the yarn winding zone of the yarn treatment channel, an optimum discharge is produced in the twisting device. Based on the characteristics of the supplied working medium, the positioning of the discharge inlet relative to the nozzle through opening is determined.
According to an exemplary embodiment of the entangling apparatus the discharge inlet has a predetermined opening width, wherein the discharge inlet has an opening width with a cross-sectional area larger than the cross-sectional area of the opening width of the nozzle through-opening.
In the entanglement device according to the invention, the total opening width of the discharge inlet of the discharge device is preferably greater than the opening width of the nozzle through-opening for the supply of pressurized working medium, so that it is ensured that the working medium used is discharged via the discharge inlet and not via the nozzle through-opening, the yarn insertion gap, the yarn inlet opening and/or the yarn outlet opening of the yarn treatment channel.
According to an exemplary embodiment of the entangling apparatus, the discharge apparatus has a plurality of discharge through-openings which are arranged linearly, undulated and/or offset from each other and each have a discharge inlet having a predetermined constant or variable opening width and/or the sum of the cross-sectional areas of the opening widths of the discharge inlets is larger than the sum of the cross-sectional areas of the opening widths of the nozzle through-openings, wherein:
the ratio is

ADkthe opening width cross-sectional area of a nozzle through opening leading into the yarn processing channel;
n 1-the number of discharge inlets; and
n 2-the number of nozzle through openings.
Depending on the shape of the cross-section of the mouth of the discharge inlet and the mouth of the nozzle through-opening, such as for example square, rectangle, trapezoid, parallelogram, etc., a suitable mathematical fit area calculation formula should be used.
According to an exemplary embodiment of the entangling apparatus the discharge zone of the discharge through-opening is centered, staggered, flanked, symmetrically and/or asymmetrically arranged with respect to the nozzle through-opening. The discharge zone shall be understood here as a zone or region from which the working medium used in the yarn treatment channel is discharged. The discharge zone can extend in its longitudinal and transverse directions over a predetermined cross section in the yarn treatment channel.
According to an exemplary embodiment of the entangling device the discharge through-opening has a discharge valve and/or a discharge flap. The outlet device may have a plurality of outlet through-openings with outlet valves and/or outlet flaps, which can be arranged optimally in the nozzle through-openings, so that the working medium used can escape via a plurality of outlet inlets. The controllable discharge can be achieved by means of a discharge valve or by means of a discharge flap.

Detailed Description
Fig. 1A and 1B show an entanglement unit 10 for entangling a synthetic multifilament yarn 2 in a longitudinal cross-sectional view or a cross-sectional view according to cross-sectional lines B-B and a-a, respectively.
The entangling device 10 has a substantially cylindrical cross-section and defines a yarn processing channel 6 having an inlet and an outlet through which the multifilament yarn 2 is fed into and out of the yarn processing channel 6.
The yarn treatment channel 6 is defined by a baffle wall 5 and a nozzle wall 1 opposite the baffle wall 5.
The nozzle wall 1 defines a nozzle through opening 3 having a predetermined opening width DW.
Via the nozzle through-openings 3, a pre-pressurized fluid working medium 4 is fed to entangle the multifilament yarn 2, which is held above and below the entangling device 10 by yarn guides 7.1 and 7.2. Ideally, the pre-pressurized fluid working medium 4 is reflected back by the baffle wall 5 of the entangling apparatus 10 and swirls, so that the individual filaments of the multifilament yarn 2 are entangled, the individual filaments being intertwined with each other and forming so-called intertwining knots. The entanglement is represented by arrow 14 in FIG. 1B.
The pre-pressurized fluid working medium 4 is preferably formed by compressed air, which is fed under constant pressure via the nozzle through-openings 3 into the yarn treatment channel 6.
A disadvantage of the entangling apparatus shown in fig. 1A is that the pre-pressurized fluid working medium 4 tries to escape via the inlet and outlet openings of the entangling apparatus 10 and here in particular may block and disturb the filament entangling process. The outflow of the supplied fluid working medium 4 from the supply and discharge openings can lead to undesirable turbulence in the yarn treatment channel 6, which prevents the formation of regular intertwining knots.
In order to dispose of the quantity of the working medium 4 which may possibly disturb the formation of intertwining knots, it is proposed according to the invention to equip the intertwining means 10 with discharge means 11.
A first exemplary embodiment of an entanglement device 100 for entangling a synthetic yarn 2 with a discharge device 11 is shown in a schematic perspective view in fig. 2.
The entangling apparatus 100 for entangling synthetic multifilament yarns 2 according to the invention has a yarn processing passage 6 through which the multifilament yarns 2 may be conveyed.
The treatment channel 6 is defined by wall sections 1,3, 8 and 9, so that a substantially cylindrical yarn treatment channel 6 is formed.
In a wall called nozzle wall 1, a nozzle through-opening 3 is arranged on one side, through which a pre-pressurized fluid working medium 4 can be fed into the yarn treatment channel. The nozzle through opening 3 is in fluid contact with the yarn treatment channel 6.
The nozzle through openings 3 are preferably capillary openings. The nozzle through-opening 3 has a capillary opening adjoining the yarn treatment channel 3 and an inlet channel 33 adjoining the capillary opening and having a larger diameter than the capillary opening.
The nozzle through-openings 3 are shown in the figures on a larger scale than their usual configuration for better understanding.
In order to introduce the synthetic multifilament yarn 2 into the entangling apparatus 100, a continuous yarn insertion gap 70 is provided in the lateral direction of the nozzle wall 1, which extends substantially parallel to the yarn fluid treatment channel 6 and through which the multifilament yarn 2 can be inserted into the yarn treatment channel 6 for subsequent treatment in the yarn treatment channel 6 to form intertwining knots.
On the other side, the yarn treatment channel 6 adjoins a baffle wall 5, at which the pre-pressurized fluid working medium 4 bounces and forms a vortex which is intended to cause entanglement and interlacing of the individual filaments of the multifilament yarn 2 and at the same time the formation of intertwining knots.
In order to allow the used or consumed working medium 4 to escape, a discharge device 11 is also provided in the entangling apparatus.
The discharge device 11 has at least one discharge through-opening 11.1 which is in fluid contact with the yarn treatment channel 6 on the one hand and with the ambient air of the entanglement unit 100 on the other hand, so that the used working medium 4 supplied via the nozzle through-opening 3 can escape via the discharge device 11 without forming turbulence which could hinder or hinder the entanglement process in the yarn treatment channel 6.
In a preferred embodiment, the discharge means 11 have discharge through openings 11.1, 11.2-11.n, which are arranged at regular intervals in the wall parts 8,9 on both sides.
It is extremely important here that the sum of the cross-sectional areas of the inlet opening widths DE of the discharge through openings 11.1, 11.2-11.n in fluid contact with the yarn treatment channel 6 is designed to be greater than the sum of the cross-sectional areas of the opening widths DW of the nozzle through openings 6 in fluid contact with the yarn treatment channel 6.
The ratio Q of the cross-sectional area AE occupied by the mouth width of the at least one discharge through opening 11.1 or of the plurality of discharge through openings 11.1-11.n to the cross-sectional width orifice AD of the nozzle through opening 3 is preferably about 1.1 to 1.8.
For example, when only one discharge inlet 110 and one nozzle through-opening 3 are provided and have a substantially circular cross-section and circumference, respectively, the ratio Q can be calculated, for example, according to the formula [1 ]:
