Description

Entanglement device for entangling synthetic multifilament yarns
Technical Field
The invention relates to a device (entanglement device) for entangling synthetic multifilament yarns by fluid-like pre-pressurized working medium.
Background
Entanglement devices are known from the prior art.
For example, DE102008018079A1 discloses a device for entangling multifilament yarns, wherein a pre-pressurized working medium, such as for example compressed air, is supplied into a yarn treatment channel via a nozzle through-opening to initiate the multifilament yarn guided therein so that it forms filament interlacing of the multifilament yarn and forms a intertwining knot.
The disadvantage of this entanglement unit is that the supplied and used pre-pressurized compressed air may escape from the yarn processing channel solely by means of the input opening for the yarn into the yarn processing channel or by means of the output opening through which the yarn of the entanglement unit leaves the yarn processing channel, which may counteract the filament entanglement process to form a entanglement.
Disclosure of Invention
The object of the present invention is therefore to provide a entanglement device in which the compressed air supplied and used for entanglement does not adversely affect the formation of the entanglement.
According to the invention, this object is achieved by means of a entanglement device.
The entangling apparatus according to the present invention allows a more active evacuation of supplied pre-pressurized fluid working medium, such as pre-pressurized compressed air, without the use of either used fluid working medium or used compressed air or air entrained by the yarn as it is directed through the yarn processing channel adversely affecting the formation of the entanglements.
With the entanglement device according to the invention, the compressed air diverted at the baffle is not retarded by the already existing compressed air used and is prevented from forming a entanglement. Otherwise, the compressed air used must escape at the input and output of the entanglement device, which may interfere with and disrupt the entanglement process.
With the entanglement device according to the invention, additional deflection and evacuation possibilities are provided to the fluid working medium used or to the compressed air flow used, so that, for example, a retarding loss of the working medium used generates a flow which does not affect the entanglement device efficiency. The working medium shall here mean, for example, a supply of compressed air which has entangled the multifilament yarn.
Since the entanglement unit efficiency is increased by means of the discharge unit, compressed air which is less pre-pressurized is advantageously required, since essentially no reaction force is required for the amount of compressed air used. This overall results in less compressed air consumption, whereby the compressed air production again requires little energy, which can be saved.
According to an exemplary embodiment of the entanglement device, the drainage means (drainage device) are arranged substantially transversely, obliquely, parallel and/or vertically with respect to the nozzle through opening run and laterally delimited by wall portions on both sides in the direction of extension of the yarn processing channel. The double-sided definition of the discharge means shall mean that the discharge means forms a through opening in the wall defining the yarn processing channel, which through opening forms a fluid contact only in the direction towards the yarn processing channel, in particular transversely to the yarn guiding direction. In addition, the discharge device is surrounded by the wall portion of the yarn processing passage and is arranged at a distance from the yarn insertion gap, which only has the function of inserting the yarn into the entanglement device. This gives the advantage that the working medium used can be better guided out of the entanglement region of the yarn processing channel and that the working medium used does not retard the entanglement process of the multifilament yarn.
According to an exemplary embodiment of the entanglement device, the drainage device is arranged adjacently, adjacently 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 a small amount of the working medium used should be discharged.
According to one exemplary embodiment of the entanglement device, the drainage device is arranged in a wall of the yarn processing channel, which is arranged opposite, in or remote from the wall, said wall corresponding to the nozzle wall and/or the baffle wall (baffle wall portion). For optimal discharge, the discharge device may be arranged in a wall of the yarn processing channel of the entanglement device at a predetermined optimal position. The disturbances and sluggish flow conditions caused by the discharge device can then be eliminated to obtain and maintain optimal entanglement of the multifilament yarns.
According to an exemplary embodiment of the entanglement device, the drainage device has a drainage through opening with a drainage inlet and a drainage outlet, wherein the drainage inlet and the drainage outlet are arranged opposite to each other in such a way that they are concentric to each other, eccentric to each other and/or laterally offset from each other. Because the discharge inlet and the discharge outlet are arranged concentrically, eccentrically or laterally offset, respectively, an undesired backflow of working medium into the yarn processing channel can be prevented. The discharge outlet may also be defined by an additional attachment to the entanglement device, wherein suitable elbows and discharge lines may be specified.
According to an exemplary embodiment of the entanglement device, the discharge inlet is arranged 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 guiding zone of the yarn processing channel.
Since the discharge inlets are arranged at the same or different levels with respect to the nozzle through openings and/or the yarn guiding zone and the yarn entanglement zone of the yarn processing channel, an optimal discharge is produced in the entanglement 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 entanglement device, the discharge inlet has a predetermined opening width, wherein the cross-sectional area of the opening width of the discharge inlet is 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 larger than the opening width of the nozzle through opening for the pressurized working medium supply, so that it is ensured that the working medium used is discharged via the discharge inlet instead of via the nozzle through opening, the yarn insertion gap, the yarn inlet opening and/or the yarn outlet opening of the yarn processing channel.
According to an exemplary embodiment of the entanglement device, the discharge device has a plurality of discharge through openings which are arranged linearly, in a wave shape and/or offset to each other and which each have a discharge inlet having a predetermined constant opening width or variable opening width, and/or the sum of the cross-sectional areas of the opening widths of the discharge inlets is greater than the sum of the cross-sectional areas of the opening widths of the nozzle through openings, wherein:
the ratio is thatIn the range of 1.1<Q<1.8, wherein,
AE k cross-sectional area of the opening width of the discharge inlet into the yarn processing channel;
AD k opening width cross-sectional area of nozzle through opening into yarn processing channel;
n1=number of discharge inlets; and
n2=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 entanglement device, the discharge zone of the discharge through-openings is centered, staggered, on both sides, symmetrically and/or asymmetrically arranged with respect to the nozzle through-openings. The discharge zone shall be understood here as the zone or area from which the working medium used in the yarn processing channel is discharged. The discharge zone can here extend in its longitudinal and transverse direction through a predetermined cross section in the yarn processing channel.
According to an exemplary embodiment of the entanglement device, the discharge through opening has a discharge valve and/or a discharge flap. The discharge device can have a plurality of discharge openings with discharge valves and/or discharge flaps, which can be optimally arranged in the nozzle openings, so that the working medium used can escape via a plurality of discharge 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 the synthetic multifilament yarn 2 according to cut lines B-B and A-A in a schematic longitudinal section view or a schematic transverse section view, respectively.
The entanglement device 10 has a substantially cylindrical cross section and defines a yarn processing channel 6 having an input and an output through which the multifilament yarn 2 is input to and output from the yarn processing channel 6.
The yarn processing passage 6 is defined by the baffle wall portion 5 and the nozzle wall portion 1 opposed to the baffle wall portion 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 yarns 2, which are held above and below the entangling device 10 by means of yarn guides 7.1 and 7.2. Ideally, the pre-pressurized fluid working medium 4 is reflected back and swirled by the baffle wall 5 of the entangling apparatus 10, whereby the individual filaments of the multifilament yarn 2 are entangled, the individual filaments being intertwined with each other and forming a so-called intertwining knot. The entanglement is indicated by arrow 14 in fig. 1B.
The pre-pressurized fluid working medium 4 is preferably constituted by compressed air, which is fed under constant pressure via the nozzle through opening 3 into the yarn processing 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 input and output ports of the entangling apparatus 10 and may here inter alia retard and disturb the filament entangling process. The outflow of the fed fluid working medium 4 from the inlet and outlet openings may lead to undesired turbulence in the yarn processing channel 6, which may prevent regular intertwining.
In order to dispose of or permit an amount of said working medium 4 which may interfere with the formation of the intertwining knots, it is proposed according to the invention to equip the entangling device 10 with a discharge device 11.
A first exemplary embodiment of an entanglement unit 100 for winding up synthetic yarns 2 with a discharge device 11 is shown in a perspective schematic view in fig. 2.
The entangling apparatus 100 according to the present invention for entangling synthetic multifilament yarns 2 has a yarn-treating passage 6 through which the multifilament yarns 2 may be conveyed.
The treatment channel 6 is defined by wall portions 1,3, 8 and 9, thereby forming a substantially cylindrical yarn treatment channel 6.
In the wall part called nozzle wall part 1, a nozzle through opening 3 is arranged at one side, through which a pre-pressurized fluid working medium 4 can be fed into the yarn processing channel. The nozzle through opening 3 is in fluid contact with the yarn processing channel 6.
The nozzle through openings 3 are preferably capillary holes. The nozzle through opening 3 has capillary holes adjacent to the yarn processing channel 6 and an inlet channel 33 adjacent to the capillary holes and having a diameter larger than the capillary holes.
The nozzle through opening 3 is shown in the figures to a larger scale than its usual structure for better understanding.
For introducing the synthetic multifilament yarn 2 into the entanglement device 100, a continuous yarn insertion gap 70 is arranged laterally of the nozzle wall portion 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 a entangled knot.
On the other side, the yarn processing channel 6 adjoins the 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 a intertwining knot.
In order to allow the used or consumed working medium 4 to escape, a discharge device 11 is also provided in the entanglement device.
The discharge means 11 have at least one discharge through-opening 11.1 which is in fluid contact with the yarn processing channel 6 on the one hand and the ambient air of the entanglement device 100 on the other hand, so that the working medium 4 used supplied via the nozzle through-opening 3 can escape via the discharge means 11 without creating turbulence which would retard or hinder the entanglement process in the yarn processing channel 6.
In a preferred embodiment, the discharge means 11 has discharge through openings 11.1, 11.2-11.N, which are arranged in the wall portions 8,9 at regular intervals on both sides.
It is of great importance here that the sum of the cross-sectional areas of the inlet opening widths DE of the outlet through openings 11.1, 11.2-11.N in fluid contact with the yarn processing 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 3 in fluid contact with the yarn processing 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 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 each has a substantially circular cross section and circumference, the ratio Q can be calculated, for example, according to the formula [1 ]:
[1]within the range of 1.1.ltoreq.Q.ltoreq.1.8, wherein:
AE is the cross-sectional area AE of the opening width DE of the mouthpiece of the discharge inlet 110; and
AD is the cross-sectional area AD of the opening width DW of the mouth of the nozzle through opening 3, where AE can be calculated according to equation [2], and AD can be calculated according to equation [3 ].
[2]AE＝DE 2 X pi, and
[3]AD＝DW 2 x pi, wherein,
DE is the opening width of the mouth of the discharge inlet 110 into the yarn processing channel 6;
DW is the opening width of the mouth of the nozzle through opening 3 into the yarn processing channel 6;
fig. 3 and 4 show a sectional view of the discharge device 11, respectively.
The discharge device 11 has a discharge inlet 110 and a discharge outlet 111. The discharge inlet 110 is in fluid contact with the yarn processing channel 6.
In fig. 3 a schematic cross-sectional view of a section line C-C according to fig. 2 is shown. From which the feed gap 70 of the yarn, the trend of the nozzle through opening 3 and the discharge through opening 11.1 and the placement of the discharge inlet 110 and the discharge outlet 111 can be seen.
In an embodiment of the entanglement device, which is not shown, the discharge inlet 110 and the discharge outlet 111 can also be arranged eccentrically or laterally offset from one another, in order to prevent backflow or backflow of the fluid working medium 4 used. Such additional eccentric or lateral misalignment of the discharge inlet 110 with respect to the discharge outlet 111 may also be achieved by an additional mount attached to the entanglement device.
Fig. 4 shows the entanglement unit of fig. 2 in a schematic longitudinal section according to the section line D-D of fig. 3, here showing a double-sided arrangement of the plurality of discharge through openings 11.1, 11.2-11.N, the nozzle through openings 3 being arranged eccentrically or offset with respect to the discharge zones 112 of the plurality of discharge through openings 11.1, 11.2-11. N.
In an embodiment of the entanglement device (not shown), the nozzle through-opening 3 may also be arranged centrally in the discharge zone 112 formed by the discharge through-openings 11.1-11. N.
Fig. 5 shows a schematic perspective view of a second exemplary embodiment of an entanglement device 100 with a plurality of drainage devices 11,11.I,11. Ii. The second and third discharge means 11.i and 11.ii have, in addition to the aligned discharge through-openings 11.1, 11.2-11.N of the first discharge means 11, discharge through-openings arranged offset from the discharge through-openings 11.1-11.N of the first discharge means 11.
As shown in fig. 5, on the yarn processing zone 6, a further row of discharge through openings is provided in the two wall portions 8 and 5. In addition, additional rows of discharge through openings may be provided in the baffle wall 9.
Fig. 6 is a schematic cross-sectional view according to section line C2-C2 of fig. 5.
The relative positioning of the additional discharge through openings of the discharge devices 11,11.I and 11.Ii extending diagonally or vertically is schematically indicated in fig. 6.
Fig. 7 shows a third exemplary embodiment of an entanglement device 100 for at least two multifilament yarns 2 according to the invention. For each multifilament yarn 2, a separate yarn treatment channel 6.1, 6.2 is provided, which can be arranged in an axially symmetrical manner to each other as shown in fig. 8.

The yarn processing channels 6.1, 6.2 are separated from each other by a discharge gap 12, through which the used working medium can be discharged to the outside towards the discharge through openings 11.1-11.N of the discharge gap 12.
Fig. 8 and 9 show the respective relative positions of the discharge through openings 11.1-11.2, the discharge gap 12 and the yarn feed gaps 70.1, 70.2 of the nozzle through openings 3.1,3.2 in the respective sectional views according to the sectional lines E-E and F-F.

[5]AE k ＝DE 2 x pi, and
[6]AD k ＝DW 2 x pi, wherein,
