  For example, in Patent Document 1, a plurality of entangled pieces in which yarn traveling spaces are formed are arranged side by side in the arrangement direction, and fluid is injected into each yarn traveling space, thereby providing entanglement to yarns traveling in each yarn traveling space. A confounding device is disclosed. According to this entanglement device, entanglement can be simultaneously given to a plurality of yarns running side by side in the arrangement direction, so that the production efficiency of the yarn can be improved.

JP 2009-108441 A

  However, in the entanglement device in which a plurality of entanglement pieces are arranged in this way, the entanglement performance may be reduced (decrease in the number of entanglement) as compared with the case where the entanglement pieces are provided alone. This phenomenon is considered due to the following reasons. The fluid injected into each yarn traveling space is discharged from the upstream and downstream ends of the entangled pieces in the yarn traveling direction of the yarn traveling space. At that time, if the fluids discharged from the respective yarn traveling spaces interfere with each other, the traveling of the yarn becomes unstable. As a result, it is considered that the yarn is detached from the original yarn path and proper entanglement is not performed.

  In view of the above problems, an object of the present invention is to improve entanglement performance in an entanglement imparting mechanism that imparts entanglement to a plurality of yarns traveling along a yarn traveling direction in a state of being arranged in an arrangement direction.

  The present invention provides an entanglement imparting mechanism that imparts entanglement to a plurality of yarns traveling along a yarn traveling direction in a state of being arranged in an arrangement direction, and is one of a plurality of yarn traveling spaces in which the plurality of yarns travel. A plurality of entanglement devices that provide entanglement to some of the plurality of yarns by injecting a fluid into the yarn traveling space of the plurality of yarns are provided along the yarn traveling direction. The two adjacent yarns are entangled by different entanglement devices.

  According to the present invention, among a plurality of yarns that run side by side in the arrangement direction, two adjacent yarns are entangled by different entanglement devices. That is, paying attention to one entanglement device, when fluid is jetted into a yarn running space where a certain yarn is running, no fluid is jetted into the yarn running space where a yarn adjacent to this yarn is running. For this reason, the fluid is not discharged from at least one of the yarn traveling spaces adjacent to each other, and mutual interference of the fluid discharged from each yarn traveling space can be suppressed. Therefore, the traveling of the yarn can be stabilized, and consequently the entanglement performance can be improved.

  For example, the two entanglement devices are provided, and the odd-numbered yarns counted from one side in the arrangement direction among the plurality of yarns are entangled by one of the entanglement devices, and the plurality of yarns Of these, even-numbered yarns counted from one side may be entangled by the other entanglement device.

  In this way, by providing a minimum of two entanglement devices, entanglement can be imparted to the two yarns adjacent to each other in the arrangement direction by different entanglement devices, as described above. Mutual interference of fluid discharged from each yarn traveling space can be suppressed.

  Specifically, the entanglement device is configured such that a plurality of entanglement pieces in which fluid supply passages for supplying the fluid to the yarn traveling space and the yarn traveling space are formed are arranged in the arrangement direction, In one entanglement device among the plurality of entanglement devices, the fluid is supplied via the fluid supply channel only to the yarn traveling space in which the yarn that is entangled by the one entanglement device travels. You can do so.

  Furthermore, in one entanglement device among the plurality of entanglement devices, the fluid supply flow path is provided only for the yarn traveling space in which the yarn to which entanglement is applied by the one entanglement device travels. It is preferable that

  In this way, when the fluid supply flow path is provided only for the yarn traveling space in which the yarn to which the entanglement is applied travels, in other words, the fluid for the yarn traveling space in which the yarn to which the entanglement is not applied travels. There is no need to provide a supply channel. In other words, the number of fluid supply channels formed in the entangled pieces can be reduced, and the yarn traveling space formed in the entangled pieces can be widened accordingly. It can be properly entangled.

  In the present invention, by interlacing two yarns that are adjacent to each other in the arrangement direction by using different entanglement devices, mutual interference of fluid discharged from each yarn traveling space can be suppressed. The performance can be improved.

(Schematic configuration of the spinning take-up device)
An embodiment of the present invention will be described. FIG. 1 is a schematic diagram illustrating an example of a spinning take-up device including the confounding imparting mechanism of the present embodiment. The spinning take-up device 1 takes up a plurality of synthetic fiber yarns Y spun from the spinning device 2 and winds them around a plurality of bobbins B to form a plurality of packages P.

It is also possible to eliminate the drawing section 3 and take up the plurality of spun yarns Y as they are with the take-up rollers 4 and 5.

  The plurality of yarns Y drawn by the drawing unit 3 are sent to the winding device 7 by the take-up rollers 4 and 5. In addition, between the take-up rollers 4 and 5, an entanglement imparting mechanism 6 that entangles many filaments constituting one yarn Y and imparts entanglement is disposed.

[First Embodiment]
(Configuration of entanglement device)
The details of the entanglement imparting mechanism 6 and the entanglement device 60 of the first embodiment will be described. FIG. 2 is a perspective view showing the entanglement device 60 of the first embodiment. As shown in FIG. 2, the entanglement device 60 supports the entanglement portion 20 that provides entanglement to the yarn Y, the restriction portions 40 that are disposed on both sides of the entanglement portion 20 in the yarn traveling direction, and the entanglement portion 20 and the restriction portion 40. The base 50 is provided.

  Here, the “arrangement direction” shown in FIG. 2 indicates a direction in which a plurality of yarns Y are arranged. The “yarn traveling direction” refers to the traveling direction of the yarn Y, and in this embodiment is a direction orthogonal to the arrangement direction. Further, the “height direction” refers to a direction in which the entangled pieces 21 constituting the entangled portion 20 are erected from the base body 50, and is a direction orthogonal to the arrangement direction and the yarn traveling direction in this embodiment. The height direction may coincide with the vertical direction, but may not necessarily coincide with the vertical direction.

  The entangled portion 20 is configured by arranging a plurality of entangled pieces 21 extending along the yarn traveling direction in a row in the arrangement direction. FIG. 3 is a cross-sectional view showing a part of the entanglement device 60 of the first embodiment, and more specifically, shows a cross section at the center in the yarn traveling direction of the four entanglement pieces 21 arranged in the arrangement direction. .

  Each entangled piece 21 is formed with one yarn running space 22 penetrating in the yarn running direction. The width of the entangled pieces 21 in the arrangement direction is the arrangement pitch of the yarns Y (two adjacent to each other in the arrangement direction). This is substantially the same as the thread interval). The cross-sectional shape of the yarn traveling space 22 in the cross section orthogonal to the yarn traveling direction is an oval shape having a major axis in the height direction, and the yarn Y travels along the yarn traveling direction at substantially the center thereof. Then, the fluid is injected into the yarn traveling space 22 so that the yarn Y traveling in the yarn traveling space 22 is entangled. The cross-sectional shape of the yarn traveling space 22 is not limited to an oval shape, and may be other shapes such as a circle or a triangle.

  In FIG. 3, a thread insertion space 24 connected to the thread traveling space 22 in the arrangement direction is formed on the thread insertion surface 23 corresponding to the left surface of the entangled piece 21. The yarn insertion space 24 is located at the center of the yarn traveling space 22 in the height direction, and is formed over the entire yarn traveling direction of the entangled piece 21.

  In FIG. 3, a fluid ejection hole 26 is formed in the fluid ejection surface 25 corresponding to the right surface of the entangled piece 21 at substantially the same position as the yarn insertion space 24 in the height direction. The fluid ejection hole 26 is provided at the center of the entangled piece 21 in the yarn traveling direction, and communicates with a fluid supply path 27 formed inside the entangled piece 21. As will be described in detail later, only the fluid supply path 27 selected every other fluid supply path 27 formed in each entanglement piece 21 is fluidized from the fluid supply source 61 via the fluid supply path 62. Is supplied. The fluid ejection hole 26 and the fluid supply path 27 correspond to the “fluid supply path” of the present invention.

  Two entangled pieces 21 adjacent to each other in the arrangement direction are arranged in a state where the yarn insertion surface 23 of one entangled piece 21 and the fluid ejection surface 25 of the other entangled piece 21 are in contact with each other. By being arranged in this way, the yarn insertion space 24 of one entangled piece 21 and the fluid ejection hole 26 of the other entangled piece 21 communicate with each other.

  Here, a portion of the yarn insertion surface 23 that is above the yarn insertion space 24 is slightly retreated inward in the arrangement direction from a portion that is below the yarn insertion space 24. For this reason, when the two entangled pieces 21 are in contact with each other as described above, a slit 28 is formed between the two entangled pieces 21 above the yarn insertion space 24. The yarn Y can be disposed in the yarn traveling space 22 through the slit 28 and the yarn insertion space 24.

  A first inclined surface 30 that extends obliquely downward from the top portion 29 toward the yarn insertion surface 23 and a second inclined surface 31 that extends obliquely downward from the top portion 29 toward the fluid ejection surface 25 are provided at the upper end portion of the entangled piece 21. Is formed. As a result, an inverted triangular space is formed in the upper part of the slit 28 by the two entangled pieces 21 adjacent to each other in the arrangement direction, and the yarn Y can be easily guided to the slit 28.

  Returning to FIG. 2, the restriction unit 40 will be described. The restricting portion 40 is a portion that defines the yarn paths of the plurality of yarns Y, and is provided on both sides of the entangled portion 20 in the yarn traveling direction, in other words, on the upstream side and the downstream side in the yarn traveling direction. The restricting portion 40 has a plurality of restricting guides 41 arranged in the arrangement direction. The regulation guide 41 is a columnar shape extending in the height direction.

  By passing the yarn Y between the two regulating guides 41 adjacent to each other in the arrangement direction, the yarn path is defined. More specifically, by passing the yarn Y through the space between two adjacent restriction guides 41 of one restriction portion 40 and between the two adjacent restriction guides 41 of the other restriction portion 40 corresponding thereto. The yarn Y is configured to travel substantially in the center of the cross section of the yarn traveling space 22. In addition, although illustration is abbreviate | omitted, the regulation part 40 is also provided with the vertical regulation part which regulates the thread | yarn Y in an up-down direction. This vertical restriction part may be provided as a member different from the restriction guide 41, or a part of the restriction guide 41 may function as the vertical restriction part.

(Granting confounding)
In order to confound the yarn Y traveling in the yarn traveling space 22, a fluid is supplied from the fluid supply source 61 to the fluid supply path 27 via the fluid supply path 62. For example, compressed air or the like is used as the fluid. The fluid supplied to the fluid supply path 27 is ejected from the fluid ejection hole 26, and the ejected fluid is supplied to the yarn traveling space 22 through the yarn insertion space 24.

  FIG. 4 is a diagram schematically showing the flow of fluid. As shown by the arrows in FIG. 4, when the fluid jetted into the yarn traveling space 22 collides with the inner wall of the yarn traveling space 22, the fluid branches to both the upper and lower sides in the height direction, and a swirling flow is generated. Entangling is imparted to the yarn Y traveling in the yarn traveling space 22 by the fluid flow at that time. Thereafter, the fluid is divided into an upstream side and a downstream side in the yarn traveling direction, and flows in the yarn traveling space 22 in parallel with the yarn Y.

  The fluid flowing in the yarn traveling space 22 toward the upstream side and the downstream side in the yarn traveling direction is eventually discharged from the end of the yarn traveling space 22 to the outside of the entangled piece 21. At this time, when the fluids discharged from the yarn traveling space 22 of the entangled pieces 21 arranged in the arrangement direction interfere with each other, the traveling of the yarn Y becomes unstable, and as a result, the yarn Y comes off from the original yarn path, Proper confounding may not be performed. Therefore, in the entanglement imparting mechanism 6 of the present embodiment, the entanglement is imparted as follows in order to prevent the fluids discharged from the yarn traveling spaces 22 from interfering with each other.

  FIG. 5 is a diagram schematically illustrating the provision of confounding by the confounding imparting mechanism 6 of the first embodiment. In addition, illustration of the control part 40 is abbreviate | omitted in FIG. Here, out of the plurality of yarns Y arranged in the arrangement direction, the odd-numbered yarn Y1 counted from the left side of FIG. 5 is defined as the yarn Y1, and the even-numbered yarn Y2 is defined as the yarn Y2. And the entanglement piece 21 which gives the entanglement to the yarn Y1 is defined as the entanglement piece 21A, and the entanglement piece 21 which gives the entanglement to the yarn Y2 is defined as the entanglement piece 21B.

  Of the two entanglement devices 60 constituting the entanglement imparting mechanism 6, in the entanglement device 60A located on the upstream side in the yarn traveling direction, the yarn Y1 traveling in the yarn traveling space 22 of the entangled piece 21A (hatched). Is entangled. On the other hand, in the entanglement device 60B located on the downstream side in the yarn traveling direction, the entanglement is applied to the yarn Y2 traveling in the yarn traveling space 22 of the entangled piece 21B (hatched). The entangled piece 21B located on the leftmost side only supplies fluid to the adjacent entangled piece 21A, and no entanglement is imparted in the yarn traveling space 22 of the entangled piece 21B.

  That is, in the entanglement device 60 </ b> A on the upstream side in the yarn traveling direction, the fluid supply path 62 (see FIG. 3) is connected to the fluid supply path 27 of the entanglement piece 21 </ b> B, and from the fluid supply source 61 via the fluid supply path 62. Fluid is supplied to the fluid supply path 27 of the entanglement piece 21B. As a result, fluid is injected into the yarn traveling space 22 of the entanglement piece 21A, and entanglement is imparted to the yarn Y1. On the other hand, in the entanglement device 60B on the downstream side in the yarn traveling direction, the fluid supply path 62 is connected to the fluid supply path 27 of the entanglement piece 21A, and the fluid of the entanglement piece 21A from the fluid supply source 61 through the fluid supply path 62 is connected. A fluid is supplied to the supply path 27. As a result, fluid is injected into the yarn traveling space 22 of the entanglement piece 21B, and entanglement is imparted to the yarn Y2.

  Thus, in the entanglement imparting mechanism 6 of the present embodiment, entanglement is imparted to the two yarns Y adjacent to each other in the arrangement direction by different entanglement devices 60. At this time, focusing on one entanglement device 60A or 60B, when fluid is injected into the yarn traveling space 22 in which a certain yarn Y is traveling, the yarn traveling space in which the yarn Y adjacent to this yarn Y is traveling. No fluid is ejected to 22. For this reason, fluid is not discharged from one yarn traveling space 22 among the yarn traveling spaces 22 adjacent to each other, and interference between fluids discharged from each yarn traveling space 22 can be suppressed. . Therefore, the traveling of the yarn Y can be stabilized, and as a result, the entanglement performance can be improved. For example, according to an experiment conducted by the present applicants (used product type: FDY SD 83 dtex / 36f, set elongation of 39.0%), entanglement is provided by every other entanglement piece 21. The confounding performance improved by about 47% from 8.3 / m to 12.2 / m.

[Second Embodiment]
FIG. 6 is a cross-sectional view showing a part of the entanglement device 60 of the second embodiment. The entanglement device 60 of the second embodiment has a configuration in which a plurality of entanglement pieces 71 are arranged in the arrangement direction. Among the entanglement pieces 71, the same reference numerals as those of the entanglement pieces 21 are given to the configurations common to the entanglement pieces 21 of the first embodiment. In the following description, the description of the configuration common to the first embodiment is omitted as appropriate, but it goes without saying that the same effect can be achieved by providing the configuration common to the first embodiment.

  As shown in FIG. 6, the entangled pieces 71 have a width that is about twice the arrangement pitch of the yarns Y (about twice the width of the entangled pieces 21 of the first embodiment) in the arrangement direction. The entangled piece 71 is formed with a yarn traveling space 22 in which the yarn Y to which the entanglement is applied travels and a yarn traveling space 72 in which the yarn Y to which the entanglement is not applied travels. That is, in the yarn traveling space 22, fluid is ejected from the fluid ejection holes 26 of the adjacent entangled pieces 71, but the fluid traveling channel for supplying fluid to the yarn traveling space 72 is provided. Absent. The yarn traveling space 72 is a U-shaped space having an opening on the upper surface of the entangled piece 71, and is formed over the entire region of the entangled piece 71 in the yarn traveling direction.

  FIG. 7 is a diagram schematically illustrating the provision of confounding by the confounding imparting mechanism 6 of the second embodiment. In FIG. 7, the illustration of the entangled piece 71 itself is omitted and only the yarn traveling spaces 22 and 72 formed in the entangled piece 71 are illustrated in order to prevent the drawing from being complicated. Here, as in the first embodiment, among the plurality of yarns Y arranged in the arrangement direction, the odd-numbered yarns Y1 from the left side in FIG. 7 are defined as the yarn Y1, and the even-numbered yarns are defined as the yarn Y2.

  Of the two entanglement devices 60 constituting the entanglement imparting mechanism 6, in the entanglement device 60A located upstream in the yarn traveling direction, the yarn Y1 travels in the yarn traveling space 22 (hatched) of the entanglement piece 71. Then, confounding is applied to the yarn Y1. On the other hand, in the entanglement device 60B located on the downstream side in the yarn traveling direction, the yarn Y2 travels in the yarn traveling space 22 (hatched) of the entanglement piece 71, and entanglement is applied to the yarn Y2. .

  Thus, in the entanglement imparting mechanism 6 of the present embodiment, entanglement is imparted to the two yarns Y adjacent to each other in the arrangement direction by different entanglement devices 60. At this time, focusing on one entanglement device 60A or 60B, when fluid is injected into the yarn traveling space 22 in which a certain yarn Y is traveling, the yarn traveling space in which the yarn Y adjacent to this yarn Y is traveling. No fluid is ejected to 72. For this reason, fluid is not discharged from one yarn traveling space 72 among the yarn traveling spaces 22 and 72 adjacent to each other, and interference between the fluids discharged from each yarn traveling space 22 is suppressed. Can do. Therefore, the traveling of the yarn Y can be stabilized, and as a result, the entanglement performance can be improved.

  In the present embodiment, the fluid supply flow path including the fluid ejection hole 26 and the fluid supply path 27 is provided only for the yarn traveling space 22 in which the yarn Y to which the confounding is applied travels. A fluid supply channel is not provided for the yarn traveling space 72 in which the yarn Y that is not traveled travels. For this reason, the entanglement piece 71 has substantially the same width as the two entanglement pieces 21 of FIG. 3, but compared to a combination of the two entanglement pieces 21, the fluid supply flow path to the yarn traveling space 72. As much as is not provided, an empty portion is generated inside the entanglement piece 71 (between the yarn traveling space 22 and the yarn traveling space 72). By using this empty portion, it is possible to widen the yarn traveling spaces 22 and 72 as indicated by broken lines in FIG. Therefore, the entanglement can be appropriately imparted to the relatively thick yarn Y while maintaining the arrangement pitch of the yarn Y as it is.

  Moreover, according to this embodiment, the number of the entanglement pieces 71 is about half that of the entanglement pieces 21 of the first embodiment, and the number of parts can be reduced.

(Modification)
In the second embodiment, the yarn running space 72 in which the yarn Y to which no entanglement is applied travels is formed in the entangled piece 71. However, it is not essential to form such a yarn traveling space 72 in the entangled piece 71, and it can be provided outside the entangled piece 71. FIG. 8 is a cross-sectional view showing a part of a modification of the confounding device 60 of the second embodiment.

  The entangled piece 81 shown in FIG. 8 is a yarn in which the yarn traveling space 22 is formed after part of the portion between the yarn traveling space 22 and the fluid supply path 27 is deleted from the entangled piece 71 shown in FIG. The traveling part 81a is combined with a fluid supply part 81b in which the fluid ejection hole 26 and the fluid supply path 27 are formed. One entanglement piece 81 is provided for every two pitches of the arrangement pitch of the yarns Y, and is arranged in a state of being separated in the arrangement direction. A space 82 sandwiched between two entanglement pieces 81 adjacent to each other in the arrangement direction functions as a yarn traveling space 82 in which the yarn Y to which no entanglement is applied travels.

  A spacer 83 is provided on the base body 50 (see FIG. 2) between the entanglement pieces 81 adjacent to each other in the arrangement direction. By providing the spacer 83, the entanglement piece 81 can be positioned accurately and easily. However, the spacer 83 can be omitted.

  Also in this modified example, the fluid supply flow path including the fluid ejection hole 26 and the fluid supply path 27 is provided only for the yarn traveling space 22 in which the yarn Y to which the entanglement is applied travels, and the entanglement is not applied. No fluid supply channel is provided for the yarn traveling space 82 in which the yarn Y travels. For this reason, the yarn traveling space 82 is wide enough to prevent the yarn Y from traveling even if the width in the arrangement direction is somewhat narrowed. Therefore, it is possible to widen the width of the yarn traveling portion 81a in the arrangement direction so that the yarn traveling space 82 is somewhat narrowed and the yarn traveling space 22 formed in the entangled piece 81 is expanded accordingly. Therefore, the entanglement can be appropriately imparted to the relatively thick yarn Y while maintaining the arrangement pitch of the yarn Y as it is.

  Moreover, according to this modification, compared with the entanglement piece 71 shown in FIG. 6, the volume of the entanglement piece 81 is increased by the amount of the yarn traveling space 82 formed between the entanglement pieces 81 adjacent to each other in the arrangement direction. It is possible to reduce the amount of raw materials necessary for producing the entangled piece 81.

[Other Embodiments]
The embodiment of the present invention has been described above. However, the form to which the present invention can be applied is not limited to the above-described embodiment, and may be changed as appropriate without departing from the spirit of the present invention, as exemplified below. Can be added.

  For example, in the above-described embodiments, the number of entanglement devices 60 provided along the yarn traveling direction is two. However, the number of entanglement devices 60 provided along the yarn traveling direction may be three or more.

  Further, in each of the above-described embodiments, the yarn Y travels between the plurality of regulation guides 41 arranged in the arrangement direction, but the form of the guide that defines the yarn path of the yarn Y is not limited to this. For example, it is also possible to employ a guide in which one or a plurality of yarn traveling portions for guiding the yarn Y are provided on one guide member, such as a U-shaped guide or a comb guide.

  Moreover, in the above-mentioned embodiment, although the control part 40 arrange | positioned at the thread | yarn running direction both sides of the entanglement part 20 of the entanglement apparatus 60 demonstrated as a structure which supports all the thread | yarns Y which pass the entanglement apparatus 60, respectively, It is good also as a structure which regulates only the thread | yarn Y to which entanglement is provided with this entanglement apparatus 60. In addition, since the restriction portion 40 disposed on the downstream side of the entanglement device 60A on the upstream side in the yarn traveling direction and the restriction portion 40 disposed on the upstream side of the entanglement device 60B on the downstream side in the yarn traveling direction are close to each other, either One may be omitted.
