  The multi-thread entanglement device 100 according to the present embodiment imparts entanglement to a plurality of multifilament yarns Y. As shown in FIGS. 1 and 2, the multi-thread interlacing device 100 includes a first member 2 (first member) in which a yarn traveling space 1 is formed as a space in which each multifilament yarn Y travels. And a second member 4 (second member) in which a fluid ejection hole 3 is formed as a flow path through which the fluid ejected into each yarn traveling space 1 flows. The first member 2 and the second member 4 are fixed to each other with a yarn insertion gap 5 into which each multifilament yarn Y can be inserted. As shown in the figure, a plurality of yarn traveling spaces 1 are arranged in parallel at predetermined intervals.

  Hereinafter, the “parallel arrangement direction” refers to the parallel arrangement direction of the yarn traveling space 1. Similarly, the “opposite direction” simply refers to the direction in which the first member 2 and the second member 4 face each other. The direction orthogonal to both the juxtaposed direction and the facing direction is defined as the “yarn traveling direction”. The yarn traveling direction is a direction perpendicular to the paper surface of FIG. 1 and the same direction as the extending direction of the yarn traveling space 1, and further, the multifilament yarn Y traveling in the yarn traveling space 1 is used. The traveling direction is the same direction.

  The first member 2 and the second member 4 are fixed to each other on the opposite side of the second member 4 and the first member 2. The third member 6 that supports the first member 2, and the first member 2 and the 4th member 7 which is provided in the other side on both sides of the 2nd member 4, and supports the 2nd member 4 bears. The third member 6 similarly extends along the first member 2 extending in the juxtaposition direction. The 4th member 7 is comprised from the support part 7a extended along the 2nd member 4 extended in the juxtaposition direction, and the connection part 7b extended perpendicularly | vertically toward the 3rd member 6 from the end of this support part 7a. Is done. The third member 6 is connected to the connecting portion 7b of the fourth member 7 by a fixing means such as bolt fastening, for example, and as described above, the third member 6 and the fourth member 7 are fixed to each other as described above. The first member 2 and the second member 4 are fixed to each other.

  With the above configuration, the plurality of multifilament yarns Y move along the juxtaposed direction as shown by the thick arrows in FIG. 1 and pass through the yarn insertion gaps 5 formed between the first member 2 and the second member 4. Are inserted into each yarn traveling space 1. In short, each multifilament yarn Y is inserted into each yarn traveling space 1 from the second member 4 side. In order to facilitate this insertion operation, the first member 2 and the second member 4 are formed with a slight taper surface for guiding the multifilament yarn Y to the yarn insertion gap 5.

  Please refer to FIG. This figure is a front sectional view of FIG. 1 as described above, and more specifically, is a view obtained by cutting the multi-thread interlacing device 100 perpendicularly to the yarn traveling direction at the center in the yarn traveling direction. As shown in the figure, the fluid injection hole 3 is formed in the second member 4 so as to have a one-to-one relationship with each yarn traveling space 1, and the juxtaposed direction is at the center in the yarn traveling direction. Are formed side by side. And in order to supply a fluid uniformly with respect to these several fluid injection holes 3, while the 1st flow path 8 connected to all the fluid injection holes 3 is formed in the inside of the 2nd member 4, A second flow path 9 communicating with the outside is formed in the support portion 7a. With this configuration, when a compressor (not shown) is connected to the second flow path 9 and a fluid such as compressed air is supplied to the second flow path 9, the fluid flows through the first flow path 8 and each fluid injection hole 3. Are sequentially supplied to each yarn traveling space 1 at a predetermined flow rate. Then, the fluid supplied to the yarn traveling space 1 is branched into two in the yarn traveling direction, and flows in the yarn traveling space 1 along the extending direction of the yarn traveling space 1. Blows out from both ends.

  Next, the shape of the yarn traveling space 1 will be described in detail. Please refer to FIG. 3A corresponds to the partially enlarged view of FIG. FIG. 3B shows another cross section that does not include the fluid ejection hole 3 in the cut surface.

  As shown in FIG. 3B, the first surface 10 as the surface of the first member 2 facing the second member 4 and the second surface as the surface of the second member 4 facing the first member 2. 11, a slight yarn insertion gap 5 is formed so that the multifilament yarn Y can be inserted. A groove 12 extending along the yarn traveling direction is formed on the first surface 10 of the first member 2, and the yarn traveling space 1 includes a groove 12 formed in the first member 2 and a second of the second member 4. It is constituted by a combination with the surface 11. Further, as shown in FIG. 3A, the yarn traveling space 1 extends in a line C (large C) indicating the flow direction of the fluid injected into the yarn traveling space 1, and this line. Formed symmetrically with respect to C.

  In the present embodiment, the cross-sectional contour of the groove 12 has a straight line portion a that extends perpendicularly from the first surface 10 in a direction away from the second surface 11, and a tip that is connected to the tip of the straight line portion a. An arc part b that draws a semicircle so as to bulge, and a bottom part c that is connected to the tip of the arc part b and extends in a direction perpendicular to the line C longer than the diameter of the fluid ejection hole 3 having a circular cross section; An arc part d connected to the tip of the bottom part c and forming a semicircle line-symmetric with respect to the arc part b and the line C; and connected to both the tip of the arc part d and the first surface 10; A straight line portion e that is a straight line that is symmetric with respect to the line C. Therefore, the cross-sectional shape of the groove 12 is a widened combination of a rectangle wider than the diameter of the fluid ejection holes 3 in the juxtaposed direction and an oval that is wider than the rectangle and is a combination of an arc and a straight line. It can be said that.

  In the above configuration, in order to start giving entanglement to a plurality of multifilament yarns Y, (1) First, a plurality of multifilament yarns Y are sucked and captured while maintaining a predetermined distance from each other. A so-called suction gun is used to insert a plurality of multifilament yarns Y into the yarn insertion gap 5 at a time in the direction indicated by the thick arrows in FIG. (2) Next, after confirming that each multifilament yarn Y inserted into the yarn insertion gap 5 is opposed to the opening of each groove 12 formed in the first member 2, the above suction is performed. Using a gun, a plurality of multifilament yarns Y are simultaneously threaded on a guide roller (not shown) provided on the downstream side of the multi-thread interlacing device 100. In addition, the guide rollers on the upstream side and the downstream side of the multi-thread interlacing device 100 so that each multifilament yarn Y travels substantially in the center of the yarn traveling space 1 in FIG. The relative position with respect to the multiple yarn interlacing device 100 is adjusted in advance. (3) Then, by introducing the compressed air into the second flow path 9 shown in FIG. 2 using the above-described compressor, as shown in FIG. The fluid starts to be ejected to the multifilament yarn Y and starts to be entangled.

  Next, the flow of the fluid injected into the yarn traveling space 1 as described above will be described in detail with reference to FIGS. 3 (a) and 3 (b). That is, as shown in FIG. 3 (a), the fluid ejected from the fluid ejection hole 3 into the yarn traveling space 1 collides with the groove bottom 13 of the groove 12 indicated by symbol c along the line C. It branches as two flows in the installation direction. The flow of the fluid branched in the juxtaposed direction draws an arc by flowing along the curved surface 14 whose contour is indicated by reference signs b and d. As shown in FIG. 3B, the fluid branched in the juxtaposed direction becomes a swirl flow that mainly draws a spiral along the curved surface 14 and blows out from both ends of the groove 12. In FIG. 3, the yarn insertion gap 5 is drawn thicker than the actual thickness in order to facilitate the understanding of the structure of the multi-thread interlacing device 100. This is only for introduction into the yarn traveling space 1 from the outside. Therefore, the thickness of the yarn insertion gap 5 is set very thin. For example, it is about 0.1 mm. Accordingly, most of the fluid injected into the yarn traveling space 1 can be blown out from both ends of the groove 12 without blowing out through the yarn insertion gap 5 to the outside. Furthermore, since the plurality of yarn traveling spaces 1 are adjacent to each other, there is almost no pressure difference between the adjacent yarn traveling spaces 1, and the yarn insertion gaps 5 between the adjacent yarn traveling spaces 1 are moved back and forth. There is almost no fluid flow. In this sense, it can be said that most of the fluid injected into the yarn traveling space 1 can be blown from both ends of the groove 12 without blowing to the outside through the yarn insertion gap 5.

  As described above, in the present embodiment, the multi-thread interlacing device 100 for confounding a plurality of multifilament yarns Y is configured as follows. A plurality of first member 2 formed with a plurality of yarn traveling spaces 1 as a space in which each multifilament yarn Y travels and a plurality of fluid injection holes 3 through which fluid to be injected into each yarn traveling space 1 flows are formed. A second member 4. According to the above structure, the structure which provides an entanglement with respect to several multifilament yarn Y is implement | achieved inexpensively with a small number of parts. Further, compared to the configuration of Patent Document 1, the pitch of the plurality of multifilament yarns Y can be narrowed.

  The multi-thread interlacing device 100 is further configured as follows. That is, each yarn traveling space 1 is configured by a combination of a groove 12 formed in the first member 2 and a second surface 11 formed in the second member 4. According to the above configuration, the processing cost can be reduced as compared with the case where each yarn traveling space 1 is configured by a combination of grooves.

  The multi-thread interlacing device 100 is further configured as follows. That is, each yarn traveling space 1 is deeper in the direction of the flow of fluid injected into the yarn traveling space 1. According to the above configuration, a swirl flow of fluid is efficiently formed in each yarn traveling space 1. The inventors of the present invention consider that this swirling flow greatly contributes to the provision of entanglement to the multifilament yarn Y.

  The multi-thread interlacing device 100 is further configured as follows. That is, each yarn traveling space 1 is axisymmetric with respect to the direction of the flow of fluid injected into the yarn traveling space 1. According to the above configuration, the mode of the flow of the fluid injected into each yarn traveling space 1 is axisymmetric. Similarly, the inventors of the present application consider that this line symmetry greatly contributes to the provision of entanglement to the multifilament yarn Y.

  The multi-thread interlacing device 100 is further configured as follows. That is, the first member 2 and the second member 4 are fixed to each other with a yarn insertion gap 5 into which each multifilament yarn Y can be inserted. Each multifilament yarn Y is inserted into each yarn traveling space 1 through this yarn insertion gap 5. According to the above configuration, a configuration in which each multifilament yarn Y can be inserted into each yarn traveling space 1 can be realized without including a movable portion.

For example, 0.1 mm. The through hole 16 corresponds to the yarn traveling space 1 in the first embodiment. On the other hand, a part of the fluid injection hole 3 through which the fluid flows is formed in the first member 2 as indicated by reference numeral 18. In other words, it is a mold in which only a part of the fluid ejection hole 3 is formed in the second member 4.
