Description

[Detailed explanation of the idea] [Technical field of invention] The present invention relates to a multi-filament fluid treatment device.

More specifically, the present invention relates to a multi-filament fluid processing device that allows each thread to be independently fluid-treated while maintaining the multi-filament threads at narrow pitch intervals.

[Prior art]

Pressurized fluid, typically compressed air, can be used for intertwining treatment between yarn and filament, crimping treatment such as false twisting, bulking treatment, etc.

On the other hand, in the filament yarn production process, it is common to process multiple yarns at the same time for production efficiency reasons.

In this case, it is very difficult to process multiple yarns at the same time while keeping the pitch between each yarn small due to ease of processing and space considerations;
The pitch up to TrrIR was considered to be the limit.

Therefore, it has been necessary to forcibly widen the pitch between adjacent yarns using a guide or the like.

As a result, unreasonable tension and friction are inevitably applied to the threads, causing fuzz, or the width of devices such as rollers that supply the threads to the fluid processing device must be adjusted to accommodate the wide pitch mentioned above. There was a problem with expanding the space.

On the other hand, in multi-filament fluid processing equipment, if the fluid injection holes become clogged, or damage such as wear or scratches occurs due to contact with the threads on the inner wall of the thread processing area, the entire equipment must be replaced. This not only resulted in extremely high costs, but also had the disadvantage of reducing productivity as it was necessary to stop yarns being processed in other yarn processing areas where there were no problems. .

Furthermore, since the pitch between adjacent thread processing areas is small, threading cannot be carried out easily.

[Purpose of invention]

The purpose of the present invention is to solve the above-mentioned problems in the conventional technology, to make it possible to process multi-filament yarns with fluid while keeping the pitch between each yarn small, and to avoid applying excessive tension and friction to the yarns. In addition, even if a problem occurs during yarn processing, only the yarn guide member where the problem occurred can be replaced, and it is possible to easily thread the yarn. It is an object of the present invention to provide a fluid treatment device for yarn.

[Structure of the idea]

The multi-filament fluid treatment device of the present invention, which is distantly related to the above object, comprises: (a) a housing member having an introduction path for pressurized fluid therein; at least three thread guide members arranged in a row at intervals along the direction of the pressurized fluid introduction path of the housing member; The yarn guide member is spaced apart so that a yarn handling area and a yarn guide slit that communicates the yarn handling area with the outside are interposed between the yarn handling area and the outside. A fluid injection hole is provided that opens toward the opposite direction, and a fluid passage that branches from the pressurized fluid introduction path of the housing member and communicates with the fluid injection hole is provided; Among the members, the thread guide members having other thread guide members on both sides each have a fluid injection hole that opens toward a thread processing area formed between the other thread guide members on both sides, and The fluid passage branching from the pressurized fluid is also configured to branch to the respective fluid injection holes.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained in detail below with reference to embodiments shown in the drawings.

FIG. 1 is a longitudinal cross-sectional view showing a multi-filament fluid treatment device for entangling treatment according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line -■ in FIG. 1.

In FIGS. 1 and 2, 1 is a single housing member, and on one side of the outer surface of this housing member 1, a plurality of thread guide members 2, 2' are arranged in a row, and bolts 3 are connected to each other. It is removably fixed.

A plurality of thread guide members 2, 2' and member 2 arranged in a row
A thread processing area 4 is formed between the adjacent members, and a thread guiding slit 5 communicating from the thread processing area 4 to the outside is interposed.

The yarn guide members 2.2' on both sides with the yarn processing area 4 and the yarn guide slit 5 interposed therebetween are provided with fluid injection holes 6, 6, respectively. The jetting direction is approximately V-shaped toward the inside of the yarn processing area 4.

A pressurized fluid introduction path 7 is provided in the housing member 1, and the pressurized fluid introduction path 7 is connected to the thread guide members 2, 2 on the outer surface thereof.
′ is branched into branch roads 8, 8′, and each branch road 8,
8' further includes a fluid passage 9 provided within the thread guide member 2°2';
9', respectively.

Among the plurality of thread guide members provided in a row, the fluid passage 9' of the outermost thread guide member 2' has one fluid injection hole 6.
However, the fluid passages 9 provided in each of the inner yarn path members 2 except for the outermost one are branched into three paths at their ends, and the yarn processing areas 4 located on the left and right sides respectively , 4 are connected to respective fluid injection holes 6, 6.

That is, the fluid passage 9 of the yarn guide member 2 is one passage that also serves as a fluid guiding path for the fluid injection holes 6, 6 provided in the left and right yarn processing areas 4, 4, respectively. Become.

Therefore, according to the above-mentioned apparatus, the guide path for the pressurized fluid to the fluid injection holes 6, 6 of the yarn processing area 4.4 located on both sides of the plurality of yarn guide members 2 is one fluid passage 9.
Since the configuration is such that the distance e between adjacent yarn processing areas can be substantially controlled by only the diameter of one fluid passage 9, multiple yarn processing areas can be arranged at a significantly small pitch. be able to place it.

In other words, it is possible to arrange at a pitch of 15 or less, which is considered difficult with conventional devices.

Therefore, according to the above-mentioned device, by forcibly widening the pitch between each yarn of a multi-filament yarn using a guide, etc., there is no damage to the yarn (and the installation space of the device can be made smaller and more compact). Become.

Furthermore, in the above-mentioned apparatus, since the fluid injection holes 6, 6 are arranged so as to sandwich the yarn guide slit 5 from both sides, the yarn may jump out from the yarn processing area 4 during fluid treatment. There is no possibility of the thread coming off like this.

Furthermore, since each yarn processing area has a yarn guide slit,
Threading is extremely easy.

On the other hand, in the present invention, since each thread guide member 2 is detachably attached to the housing member by the bolt 3, it is only necessary to replace the thread guide member in which a problem has occurred.

Furthermore, since it is only necessary to prepare three types of thread guide members, the thread guide members can be industrially mass-produced and the cost can be reduced.

3 and 4 show a fluid treatment device for multi-filament yarns for interlacing, which is another embodiment of the present invention. Instead of the outer surface of the other member 10 such as ceramics
It is designed to provide a.

According to the configuration of this embodiment, there is no need to process the outer surface of the housing member 1 into irregularities consisting of planar protrusions, so manufacturing and assembly are facilitated, and gaps are less likely to occur at the joints of each member when assembled. Therefore, it can be said that this is a more preferable configuration.

Although the above embodiments are all related to entangling processing devices, the present invention can also be used in similar fluid processing devices such as other false twisting processing, bulking processing, etc.

Further, the cross-sectional shape of the yarn processing area is not limited to the pentagonal shape in the embodiment, but may be circular, elliptical, or other polygonal shapes depending on its use and purpose.

[Effect of idea]

As described above, the multi-filament fluid treatment device of the present invention includes: (1) a housing member having an introduction passage for pressurized fluid therein; at least three thread guide members arranged in a row at intervals along the direction of the pressurized fluid introduction path of the housing member; are separated so that a yarn handling area and a yarn guide slit that communicates this yarn handling area with the outside are interposed between the yarn handling area and the outside, and A fluid injection hole is provided that opens from the pressurized fluid introduction path of the housing member, and a fluid passage that branches from the pressurized fluid introduction path of the housing member and communicates with the fluid injection hole is provided; Among the members, the thread guide members having other thread guide members on both sides each have a fluid injection hole that opens toward a thread processing area formed between the other thread guide members on both sides, and The present invention is characterized in that the fluid passages branching from the pressurized fluid are also configured to branch to the respective fluid injection holes.By adopting the above-mentioned configuration, the present invention achieves the following effects. It has excellent effects.

In other words, (1) the fluid passage in the yarn guide member also serves as a fluid guide path for the respective fluid injection holes for the left and right yarn processing areas; therefore, the pitch between the yarn handling areas is made as small as possible; It becomes possible to fluidly process multi-filament threads while maintaining a small pitch between each thread.

Therefore, unreasonable tension and friction are not applied to each yarn, and processing can be performed in a small installation space.

■ In the above-mentioned device, the two fluid injection holes are arranged to sandwich the yarn guide slit from both sides, so it is possible to prevent the yarn from coming off from the yarn processing area during fluid treatment. Nothing will happen.

(2) Furthermore, since each thread processing area has a thread guiding slit, threading can be carried out extremely easily despite the small pitch between adjacent thread processing areas.

■ In addition, even if the fluid injection hole becomes clogged, or if damage such as wear or scratches occurs due to contact with the yarn on the inner wall of the yarn processing area, there is no need to replace the entire device. Since it is only necessary to replace only one thread, the cost is not only extremely low, but also, since there is no need to stop threads being processed in other thread processing areas where there is no problem, productivity can be improved.

■Furthermore, since it is only necessary to prepare three types of thread guide members, the thread guide members can be industrially mass-produced and the cost can be reduced.
