Abstract

A texturising nozzle for synthetic filaments is openable and closable to facilitate lacing up. The nozzle comprises a two-part carrier structure with the parts (10, 12) movable towards and away from each other to open and close the nozzle. The thread path through the nozzle is defined by means of insert elements (18, 20) releasably mounted on the carrier structure at least in that region of the path in which the main texturising step is performed. A thread infeed passage (24) and a (preferably single) fluid infeed passage bring thread and treatment fluid together at a junction location, and a guide passage (26) (which preferably widens in the downstream direction) leads the thread and fluid from the junction location to the texturising region (28).

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a yarn textured processing machine equipped with a textured processing nozzle. The yarn passes through the texturing nozzle and travels substantially along a predetermined yarn path. During passage through the texturing nozzle, the yarn is subjected to the action of a yarn treatment fluid, typically a gas or steam. "Yarn" as used herein refers to all continuous fiber elements, in particular, but not exclusively, whether monofilament or multifilament;
Figure 3 shows a filamentary synthetic fiber material.

[Conventional technology]

The invention relates more particularly to a texturing nozzle of the generally known type for use in the general process of texturing yarn by the action of a treatment fluid, the nozzle being provided with a texturing chamber. , within this chamber the textyard action takes place. This chamber has an elongated shape;
It forms part of the thread path that passes through the nozzle. The chamber wall is perforated through which the processing fluid is discharged, usually in a direction transverse to the yarn path. The nozzle is equipped with a device for combining the fluid and the thread and directing it into the chamber. Before entering the texturing chamber, the fluid may be configured to advance the yarn and force the yarn into the chamber, but after the fluid enters the chamber, the fluid may be pumped through holes in the chamber wall. The action of escaping and advancing this thread is at least substantially reduced. The chamber is designed to generate intense turbulence and/or vibrations of the fluid within the chamber, possibly at a resonant frequency. The fluid may be hot steam or gas, preferably hot air, but steam may also be used. The temperature of the fluid after the yarn and fluid are combined and before entering the textyard processing chamber and the time that the fluid and yarn are in the nozzle are such that the yarn is preferably brought close to a predetermined temperature that varies depending on the yarn material. It is preferable that the temperature is such that it can be heated very close to the temperature at which it becomes plasticized. The holes in the chamber wall are preferably in the form of long slits distributed equally in the direction of the yarn path around the yarn path.

An example of a textured nozzle of the general type described above, with a preferred axially elongated slit in the chamber wall, is disclosed in U.S. Pat.

[Problem to be solved by the invention]

There are particular concerns regarding the nozzles required for processes such as texturing. That is, the texture yarding process is relatively complex, and it has a large effect on the physical properties of the yarn material itself, such as dyeability. In such nozzles, slight variations in the morphology between nozzles or over time of a single nozzle will cause significant variations in the physical properties of the yarn. At the very least, this will cause difficulties for the end users of yarn.
Such yarns result in products of inferior quality. For example, a fabric with streaks will be produced based on the dye spots of the yarn used. Also, creating a series of textured nozzles and uniformly controlling their operating characteristics presents a very demanding problem of accurate manufacturing within acceptable manufacturing costs.

The present invention aims to provide a particular type of textured nozzle that allows precise manufacturing in order to impart well-controlled and reproducible, i.e. stable, properties to the textured yarn.

[Means to solve the problem]

An object of the present invention is to provide a texturing nozzle for texturing yarn while the yarn moves through a generally straight path of a yarn processing nozzle, the object of which is to provide a textured processing nozzle for texturing a yarn while the yarn moves through a generally straight path of a yarn processing nozzle. means for merging the yarn and the processing fluid; and a wall located on a passage downstream of the merging position as seen in the direction of yarn movement and provided with a hole for discharging the treatment fluid in a direction transverse to the passage. and a guide path constituting a portion of the passageway between the merging position and the textured processing chamber, the means for merging the yarn and the processing fluid in the merging It is composed of a yarn feed path that opens at the yarn feed path, and a single fluid supply path that has an axis inclined at a small angle with respect to the yarn feed path and projects to the merging position, The fluid supply path is provided with a tube having a through hole and means for fixing this tube in a replaceable manner in the passage so that all the processing fluid flowing into the guide path is necessarily sent through the tube, and the The replaceable tube comprises a plurality of tubes having through-holes with different hole configurations such as hole cross-sectional dimensions and/or tube lengths and/or hole shapes selected depending on the properties of the textured yarn to be produced. This is achieved by means of a yarn texturing nozzle, which is characterized by being one of them.

〔Example〕

As an example of the invention, a two-part retractable nozzle according to the invention and modifications thereof will be described in detail below with reference to the accompanying drawings.

The nozzle body shown generally in FIGS. 2 and 3 includes a first metal member 10A shown in FIG. 2 in an axial cross-sectional view and a cross-sectional view in FIG. It is composed of a second metal member 12A which is shown as 10A and has a complementary relationship with the first metal member 10A. Each member has a pair of planar surfaces 16A, the pair of surfaces 16A having a central longitudinal direction comprising a first hole 15 (FIG. 2), a second hole 17 (FIG. 3) and a groove 60 (FIG. 2). placed on both sides of the recess. Each sealing surface 16A has a recess 61 for accommodating a guide member provided on the other member.

The respective members are complementary to each other, and the surface 16A on the member 10A is sealed to the other member 12.
A tubular body is provided which is capable of engaging the upper surface of A and has a through hole formed by hole 15, hole 17 and groove 60. In use, the thread runs along a defined thread path that includes the axis of the through hole.
Viewed in the direction of thread travel, two holes 15 join together to form a chamber at the upstream end of the yarn path, and two holes 17 join together to form a chamber at the downstream end of the yarn path. Each member 10A, 12A constitutes a holding member for a plurality of insert members which, in use, are placed in the chambers formed by the two holes 15, 17, respectively.
These plurality of insert members define the yarn path within each chamber.

In FIGS. 2 and 3, only the insert 22 in the downstream chamber is shown. The two insert members 22 together define a texturing chamber at the downstream end of the threadway. Another insert member is arranged in the chamber at the upstream end for feeding the thread, and if necessary, a thread guiding insert is arranged between the upstream insert member and the downstream insert member 22 (not shown). figure).

Each insert member 22 is comprised of a wall portion 40 (FIG. 2) and flanges 41, 43.
Each flange has a hole 1 in the member 10A or 12A in which the respective insert member 22 is fitted.
7, as shown in FIG. 3, and fixed with screws 42. Both wall portions 40 constitute the walls of the textured processing chamber and are securely supported by flanges 41 and 43 at both ends. The tubular wall formed by the wall portion 40 has 12 parts extending in the longitudinal direction.
A book slot 44 is provided. As shown in FIG. 3, each insert member 22 has five perfectly shaped slots formed on the joining surface of both insert members 22, and when both insert members 22 are joined, a perfectly shaped slot is formed. Two radial slots are formed. Each slot 44 extends from one end of the respective insert member 22 to the other, i.e. between the flanges, so that in the wall in the area between the flanges:
radially penetrating (not shown). These slots 44 thus communicate the textured processing chamber 28 with an exhaust chamber 46 formed by the holes 17 around the wall 40. Fluid exits the exhaust chamber 46 via an exhaust passageway 50 in each member 10A, 12A.

Each member is also provided with a stud (not shown) that mounts the nozzle to a suitable support structure (not shown) of the texturing equipment. The stud support members of the support structure are configured to be relatively movable so that the nozzle can be opened and closed. Each main body part is also partially housed in a casing 54 (FIG. 3) made of a material with low thermal conductivity, and when in use, the main body members 10A, 12A
designed to protect the operator from hot metal parts.

FIG. 1 is an axial cross section of the infeed portion of the nozzle, and is a cross section at a phase angle of 90° with respect to the cross section of FIG. Therefore,
A joining line 76 between main body members 10A and 12A is visible.
Each groove 60 has a triangular cross section, and the guide path 26A formed between both grooves 60 has a quadrangular cross section. The yarn feeding path 64A is formed simply by a groove having a triangular cross-sectional shape formed in an insert member 78 attached to the hole 15 of the main body member 12A.
That is, the surface of the insert member 80 attached to the hole 15 of the main body member 10A that faces the yarn feeding path 64A is a flat surface.

Insert member 80 has a recess 82 into which is fitted an O-ring 84 disposed about the air inlet of hole 86. Recess 82 is fully integrated with fluid supply channel 88 . The fluid supply path 88 is arranged in the main body member 10A by an appropriate method (details of the arrangement method are not shown). The fluid supplied from the fluid supply path 88 is guided to the hole 86 and flows into the hole 87 . Hole 87 located downstream of hole 86
In the upper part there is a closing screw 8 which is open at the end face of the insert member 80 and is provided with a sealing washer 91.
A thread is cut in order to screw in 9. hole 87
This opening is a working opening and is provided solely for the purpose of processing the lower part of the hole 87 for the purpose described below, and is not intended for normal use of the nozzle.
9 or other conventional closure means.

The lower part of the hole 87 located downstream of the hole 86 is
It consists of a threaded part 90 and a smooth part 92 beyond which the thread is not cut. Hole 94 of relatively small cross section allows smooth portion 92 and insert member 8 to
It communicates with a recess 98 formed on the bottom surface of 0. Further, the lower end of the hole 94 opens into an enlarged portion 72 formed at the upper end of the guide path 26A. The axis of the hole 94 and the insert member 80 adjacent the hole 94
The angle X between the side surface and the side surface is made as small as possible.

A tube 100 is fitted within the hole 94 and secured in place by any suitable method. In the illustrated example, this method involves sandwiching a compressible elastic washer 102 between the annular end face of the cavity 87 and the bush 104. The hollow cylindrical nut 106 screwed into the threaded portion 90 is further screwed to push the bush 104 toward the bottom of the cavity 87 to compress the elastic washer 102 .
2 to tighten the outer surface of the tube 100.
00 is fixed. Hole 86 and tube 100 are communicated by an inner bore of nut 106. tube 10
0 is held in relation to insert member 80 such that the distal end of tube 100 slightly protrudes into enlarged portion 72 . Of course, in order to reliably determine the relative position of the tube 100 with respect to the insert member 80, the tube 100 may be formed of a tube of a predetermined length, and the tube may be provided with means for positive and positive positioning. can. In this example, tube 10
Hole 96 at 0 is the only fluid passageway. Moreover, the insert member 80 in this case additionally has the function of a support member for the tube 100, to which the tube 100 is removably fixed by the above-mentioned fixing means. This fixing means is a sealing member, in this case a washer 102, which is designed to ensure that all the supplied fluid passes through the tube 100 without leaking.

In the embodiment of FIG. 1, the pipe 1 which is the fluid passage
The shape of the 00 hole 96, particularly its cross-sectional dimension, is selected so that the flow rate of the processing fluid at a predetermined pressure is a required flow rate. By replacing the tube 100 with a hole 96 having a different effective cross section, the flow rate of the process fluid can be changed. The closure screw 89 is removed and the tube 100 can be replaced through the working opening in the upper end of the hole 87. The ability of such a pipe to adjust the flow rate of the process fluid supply is very large, and an external flow rate adjustment device such as a throttle valve in the fluid supply path 88 is not required. However, the present invention does not limit the adjustment of the processing fluid supply amount by a combination of the flow rate adjustment tube 100 and other external flow rate adjustment devices. It is preferable that each nozzle is provided with several flow control tubes 100 having different hole shapes, that is, a set of flow control tubes having different hole cross-sectional dimensions, pipe lengths, and/or hole shapes.

The cross section of the hole 96, which is the fluid passageway of the tube 100, is preferably circular. Although the illustrated example tube 100 has the same cross-sectional shape over its entire length, this need not be the case. The length of the tube 100 is
It is preferable to consider other operating conditions, such as the type of fluid to be treated, the supply pressure, etc., and select such a method that the fluid is blown out from the outlet end of the pipe in a straight line with as little turbulence as possible. For this purpose,
Adjustment with relatively short orifices is inadequate. A short orifice will create uncontrollable turbulence at the upstream and downstream ends of the orifice, and such turbulence will disturb the uniform textured process.
There is a risk that the textured processing state may vary from time to time and from nozzle to nozzle. Furthermore, in order to avoid unforeseen disturbances when the fluid is sent from the tube 100 to the guide path formed by the groove 60, the tube 100 is aligned as much as possible with the axis of the guide path. In other words, the angle X is made as small as possible, and at the same time, the yarn feed path 64A is provided only in the insert member 78. or,
In order to send fluid to the guide path without causing turbulence, the shape of the merging area formed by the enlarged portion 72 is tapered toward the guide path as shown. However, the enlarged portion formed on the main body member 12A may be omitted as shown by the chain line in the figure.

An example of the dimensions of each component of the embodiment shown in FIG. 1 is shown below.

Processing fluid Hot air (air) Supply fluid pressure in cavity 87 6 bar Length ^of pipe 100 12 mm Angle It is desirable that the angle is 30° or less, and it is very good if it is 20° or less. As a manufacturing problem, it is usually considered impossible to reduce the angle X to less than 10 to 12 degrees. The length of the tube 100 is preferably at least 4 mm, preferably in the range of 6 to 30 mm.

The lower end of the tube 100 is preferably placed as close as possible to the line of thread passage through the nozzle without risking contact with the thread. In order to reliably control the relative position of the lower end of the tube 100 with respect to the yarn path, for example, a flange may be provided at a portion away from both ends of the tube, or a bush 104 may be placed between the tube 100 and the lower end.
It may be fixed to the pipe 100 or formed integrally with the pipe 100.

Although it is possible to pass a passage through the closing screw 89 and use this passage to send the processing fluid into the pipe 100, it is better to use the method shown in the figure, and it is better not to use the closing screw 89 to send the processing fluid. Good.
If a method is adopted in which the processing fluid is sent into the tube 100 through the closure screw 89, replacing the tube 100 becomes complicated. That is, it may be necessary to remove the fluid supply tube from the closure screw in order to remove the closure screw and allow replacement of the tube 100, and/or
Alternatively, flexible fluid supply tubing may have to be used. Furthermore, another method for replacing the tube 100 is to remove the insert member 80 and replace the tube from the lower end (downstream portion) of the hole 94, but this method is more complicated. Furthermore, it is also possible to use various insert members 80 with holes 94 of different diameters instead of using the pipe 100, but it is possible to use various insert members 80 with various holes 94 for each nozzle. Having only one set is disadvantageous in terms of cost.

The thread path passing through the nozzle is preferably straight, and the processing fluid sent through the fluid supply path may join the thread path at a small angle.

A configuration in which this relative relationship between the yarn path and the fluid supply path is reversed is disclosed in U.S. Pat. is highly complex, the nozzle is susceptible to damage, and the system is disturbed at locations where the yarn path is bent to join the straight fluid supply path.

Replaceable telescoping tubes, such as tube 100 shown in FIG. 1, can of course be used with both integral and segmented texturing nozzles. In the latter case, there is no insert assembly at the infeed and/or outfeed end.

Various modifications can be made within the scope of the claims of this invention. For example, instead of having a constant cross-sectional shape as shown in the illustrated example, the bore of a replaceable tube such as tube 100 may be slightly tapered and conical. In this case, the holes are tapered in the direction of fluid flow. In other words,
The cross-section of the downstream end of the hole is minimized, with a small angle between the axis of the hole and a straight line contained in the wall of the hole. The maximum practical angle on one side of this taper would be about 5°. By forming the fluid supply path into a tapered shape in this manner, the fluid flow velocity at the upstream end of the pipe can be reduced while maintaining the fluid flow velocity at the downstream end of the pipe at an appropriate value, thereby reducing friction loss. Still other modified embodiments will be described with reference to FIGS. 4 and 5.

FIG. 4 shows an embodiment in which the thread feeding end of the nozzle shown in FIG. 1 is modified. The method of illustration in FIG. 4 corresponds to that in FIG. That is, it is an axial sectional view of a state in which the main body members 10D and 12D are assembled together at the joint surface 76 to form a nozzle. In this case too, the principle of identical reference numerals and identical parts has been used to the extent possible. In the case of Fig. 4, there is no thread feeding insert assembly. The thread feeding path 64B is formed directly in the main body member 12D. That is, the hole 15 shown in FIG. 2 is omitted. Even in this case, the single tubular flow rate adjustment member 124 is configured to adjust the flow rate of the processing fluid. The structure of this flow rate adjustment member 124 is based on the simple pipe 10 in FIG.
It is relatively more complex than that of 0. The structure will be explained below.

Adjustment member 124 is mounted in a hole 87A similar to hole 87 in FIG. Hole 87A is formed directly in main body member 10D. Adjustment member 124 projects into hole 94A. Hole 94A is hole 87
It comes out from the lower end of A and opens into the groove 60A, making the two communicate. The cross section of hole 94A is relatively small compared to that of hole 87A, creating an annular surface 126 at the bottom of hole 87A. Processing fluid is fed into the holes 87A through fluid supply passages 86A suitably formed in the body member 10D. The upper end of the hole 87A opens into the end surface of the main body member 10D to form a working opening. The working opening is threaded for screwing in a closing screw 89A. Therefore, in this embodiment, the main body member 10D itself is used as a holding member for holding the flow rate adjusting member 124.

The flow rate adjusting member 124 (FIG. 5) is composed of a tubular main body portion 128 having an enlarged portion 130 at the upstream end, and a flange 132 formed close to the enlarged portion 130 at a constant interval. As shown, enlarged portion 130 and flange 132 are connected to tubular body portion 128.
Although they are formed integrally with the main body portion 128, they may be formed separately and fixed to the main body portion 128. The outer diameter of the enlarged portion 130 is equal to that of the spiral spring 134 (Fig. 4).
It is sized so that it can be inserted into one end of the holder and held by a spiral spring 134. The adjustment member 124 is the spring 1
34 is pushed into the helical line of spring 134 until it abuts the top surface of flange 132. spring 134
The upper end of the hole 87A engages the spring receiving projection 136 of the closing screw 89A. The free length of spring 134 is greater than the length of hole 87A, so spring 13
4 is compressed and its repulsive force presses the flange 132 against the annular surface 126. In this case flange 1
An edge 138 projects axially from 32 and joins annular surface 126 . If the surface shape of the annular surface 126 is not uniform, the flange 132
It has flexibility to the extent that it can be deformed according to the surface shape of the annular surface 126 by the pressing force of 34. The flange 132 deforms according to the surface shape of the annular surface 126 such that the annular surface 126 and the edge 138 join in a sealing manner to completely encircle the entrance of the hole 94A. The flange 132 and the spring 134 constitute an elastic fixing device that fixes the flow rate adjusting member 124 in a fixed position.

The through hole of the flow rate adjusting member 124 is composed of a hole 140 having a uniform circular cross section in the longitudinal direction and a tapered hole 142 smoothly connected to the hole 140.
The through-hole should be shaped like this, at least the entrance of the through-hole,
By forming it in a tapered shape, even if the inlet part is damaged or the inlet part is poorly machined, the influence of such defects on the performance of the flow rate adjusting member 124 can be reduced. It is the holes 140 of uniform circular cross section that actually regulate the flow rate of the processing fluid. In order to exhibit the flow rate adjustment function, the length of the hole 140 is preferably equal to the diameter of the hole 140 in the minimum case, and preferably up to three times the diameter of the hole 140. tube 12
The conditions regarding the angle between the axes of the pipe 100 and the yarn feeding path 64B are as follows:
The conditions are the same as those for the relationship. Flow rate adjustment member 12
4 can of course also be used with appropriate modifications of the embodiment of FIG.

Since the end of the spring 134 grips the head 130 of the flow rate adjustment member 124, the flow rate adjustment member 124 and the spring 134 can be removed together by removing the closing screw 89A. The spring 134 and the closure screw 89A may be connected in any suitable manner so that the spring 134 and the closure screw 89A can be removed at the same time, but in this case, the flow rate adjustment cannot be performed when the closure screw 89A is turned for installation and removal. The coupling method must not allow the member 124 to rotate.

〔Effect of the invention〕

The texturing nozzle according to the invention is constructed as described above so that all fluids supplied flow through a single fluid supply channel or tube that can be precisely manufactured and used in combination. It turns out. Therefore, high-quality textured yarn can be produced simply by accurately arranging this single fluid supply path with respect to the guide path and yarn feeding path between the confluence point of the yarn and processing fluid and the textured processing chamber. be able to.

Furthermore, the fluid supply path can be formed by preparing tubes with different cross-sectional areas and replacing the tubes as appropriate, so that the characteristics of the resulting textured yarn can be easily adjusted. This ability to precisely shape the fluid supply path ensures precise control of the process fluid supply without the need for complex control devices external to the nozzle. Can be done.
