Description
Technical Field
The present invention relates to an interlacing device for imparting interlacing to a plurality of yarns running in a yarn running direction in a state of being aligned in an alignment direction.
Background
For example, patent document 1 discloses a crossroad apparatus as follows: a plurality of interlacing sheets having thread running spaces formed therein are arranged in an array direction, and fluid is ejected to each thread running space, thereby imparting interlacing to the thread running in each thread running space. According to this interlacing device, since interlacing can be simultaneously applied to a plurality of yarns that are aligned and advanced in the alignment direction, the productivity of the yarns can be improved.
Patent document 1: japanese patent laid-open publication No. 2009-108441
However, in the case of the cross-machine apparatus in which a plurality of cross-machine segments are arranged in this manner, cross-machine performance may be degraded (the number of cross-machines may be reduced) as compared with the case where the cross-machine segments are provided as a single body. This phenomenon is considered to be based on the following reason. The fluid ejected into each of the filament running spaces is discharged from the upstream end and the downstream end of the filament running space in the running direction of the filament. At this time, if the fluids discharged from the respective yarn running spaces interfere with each other, the running of the yarn becomes unstable, and as a result, the yarn is considered to be separated from the original yarn passage, and proper crossing cannot be performed.
Disclosure of Invention
In view of the above problems, an object of the present invention is to improve interlacing performance in an interlacing device that imparts interlacing to a plurality of yarns running in a yarn running direction while being aligned in an alignment direction.
The present invention is a crosser for applying crossovers to a plurality of yarns running in a running direction of the yarns while being aligned in an alignment direction, the crosser comprising: a crossing section in which a plurality of yarn running spaces through which the plurality of yarns run are formed in the arrangement direction; a fluid supply unit configured to inject a fluid into the plurality of yarn running spaces to thereby apply crossovers to the plurality of yarns running in the plurality of yarn running spaces, respectively; and an interference suppression mechanism configured to suppress interference between the fluids ejected from the fluid supply unit into the plurality of filament running spaces after the fluids are discharged from upstream ends or downstream ends of the plurality of filament running spaces in the filament running direction.
According to the present invention, the interference suppression means can suppress the mutual interference of the fluids discharged from the upstream side end or the downstream side end of the plurality of filament running spaces in the running direction of the filament. Therefore, the running of the yarn can be stabilized, and the interlacing performance can be improved.
For example, it can be formed as: the interference suppressing means is provided with a plurality of partition walls, and each of the plurality of partition walls is disposed between two extension spaces adjacent to each other in the arrangement direction among a plurality of extension spaces extending the plurality of filament running spaces in the filament running direction.
By providing the partition wall between the two extension spaces adjacent to each other in the arrangement direction in this manner, the fluid discharged from each of the filament running spaces is suppressed from flowing into the adjacent extension space, and therefore, the fluid discharged from each of the filament running spaces can be suppressed from interfering with each other. Therefore, the running of the yarn can be stabilized, and the interlacing performance can be improved.
Here, it is preferable that the plurality of partition walls are provided on an upstream side and a downstream side of the yarn winding portion in the yarn running direction.
By providing the plurality of partition walls on the upstream side and the downstream side of the interlacing portion, the running of the yarn can be stabilized both before the yarn enters the interlacing portion and after the yarn exits from the interlacing portion, and therefore the interlacing performance can be further improved.
Preferably, the partition wall is disposed at the center of two of the elongated spaces adjacent to each other in the arrangement direction.
When a partition wall is disposed at the center of two extension spaces adjacent to each other in the arrangement direction, the string passage is present at substantially the center of two partition walls adjacent to each other in the arrangement direction, when viewed in a different manner. Therefore, the flow of the fluid acting from both sides in the arrangement direction can be substantially equalized with respect to the yarn running through the yarn passage, and the yarn can be effectively suppressed from swinging in the arrangement direction. As a result, the running of the yarn can be further stabilized, and the interlacing performance can be further improved.
Preferably, the partition wall is provided over a range that includes a range of formation of the yarn running space and is wider than the range of formation in a height direction orthogonal to the arrangement direction and the yarn running direction.
By providing the partition walls in such a range, it is possible to more reliably prevent the fluid discharged from each filament running space from passing over the partition walls and entering the running spaces of the adjacent filaments. Therefore, the fluid discharged from each of the filament running spaces can be effectively inhibited from interfering with each other. As a result, the running of the yarn can be further stabilized, and the interlacing performance can be further improved.
It is preferable that a partition body having the plurality of partition walls and a support portion integrally supporting the plurality of partition walls is provided.
By providing a plurality of partition walls as a part of the partition body integrally configured in this manner, the number of components can be reduced, and the installation of the plurality of partition walls becomes easy.
In this case, it is preferable that a fitting portion is formed on a base body supporting the entanglement portion, and a fitting portion capable of fitting with the fitting portion is formed on the partition body, and the partition body is positioned with respect to the base body by fitting the fitting portion with the fitting portion.
In this way, the positioning of the division body can be performed easily and with high accuracy by positioning the division body with respect to the base body by fitting the fitting portion formed on the division body and the fitted portion formed on the base body.
Further, it is preferable that the separator is detachable from the base.
In the interlacing portion, there are cases where maintenance is required such as yarn waste accumulating in the yarn running space. In this case, if the partition body is detachable from the base body, the maintenance work of the winding portion can be easily performed by detaching the partition body from the base body.
Effects of the invention
In the present invention, the entanglement suppressing means for suppressing the interference between the fluids ejected from the fluid supply unit into the plurality of filament traveling spaces after the fluids are discharged from the ends of the plurality of filament traveling spaces in the filament traveling direction is provided, whereby the entanglement performance can be improved.

Detailed Description
(schematic structure of spinning draft device)
Embodiments of the present invention will be explained. Fig. 1 is a schematic diagram showing an example of a spinning draft device provided with a crosswinding device. The spinning traction device 1 draws each of the plurality of synthetic fiber yarns Y spun from the spinning device 2, and winds each of the plurality of synthetic fiber yarns Y around each of the plurality of bobbins B to form a plurality of packages P. The vertical and longitudinal directions shown in fig. 1 are defined as vertical and longitudinal directions of the spinning draft device 1.
The spinning draft device 1 includes a stretching section 3, draft rollers 4 and 5, a crosser 6, a winding device 7, and the like. First, in the spinning device 2, a polymer supplied from a polymer supply device (not shown) including a gear pump or the like is extruded downward from a spinneret, and a plurality of yarns Y are spun in a state of being arranged in the depth direction of the paper surface of fig. 1.
The plurality of yarns Y spun from the spinning device 2 travel in a yarn path along the stretching section 3, the drawing roller 4, the crosser 6, and the drawing roller 5 in a state of being arranged in the depth direction of the drawing sheet of fig. 1. The plurality of yarns Y are distributed in the forward and backward directions from the drawing roller 5, and are wound around the plurality of bobbins B by the winding device 7.
The stretching section 3 is disposed below the spinning device 2. The stretching unit 3 includes a heat-insulating box 10 and a plurality of heating rollers (not shown) housed in the heat-insulating box 10. The stretching section 3 stretches the plurality of yarns Y spun from the spinning device 2 by a plurality of heating rollers while heating the yarns, respectively.
The plurality of yarns Y stretched by the stretching unit 3 are sent to the winding device 7 by the drawing rolls 4 and 5. Further, between the drawing rolls 4 and 5, a crosser 6 for twisting a plurality of single fibers constituting one yarn Y to impart crossovers is disposed. The crosser 6 will be described later in detail.
The winding device 7 includes a body 11, a turn table 12, two bobbin holders 13, a support frame 14, a contact roller 15, a traverse device 16, and the like. The winding device 7 rotates the bobbin holder 13 to simultaneously wind the plurality of yarns Y fed from the drawing roller 5 around the plurality of bobbins B to form a plurality of packages P.
A disc-shaped turntable 12 is attached to the machine body 11. The turntable 12 is rotationally driven by a motor not shown. Two long cylindrical bobbin holders 13 are supported by the turntable 12 in a cantilever manner in a posture extending in the front-rear direction. A plurality of bobbins B are mounted on each bobbin holder 13 in an aligned state along the axial direction thereof. The two bobbin holders 13 can be switched between an upper winding position and a lower retracted position by the rotation of the turntable 12.
The support frame 14 is an elongated frame-like member extending in the front-rear direction. The support frame 14 is fixedly attached to the machine body 11. At the lower portion of the support frame 14, a roller support member 17 long in the front-rear direction is attached to the support frame 14 so as to be movable up and down. The roller support member 17 is rotatably supported by the contact roller 15 extending in the axial direction of the bobbin holder 13. The contact roller 15 comes into contact with the package P being formed, and applies a predetermined contact pressure to the package P, thereby adjusting the shape of the package P.
The traverse device 16 includes a plurality of traverse guides 16a arranged in the front-rear direction. The traverse guides 16a are driven by a motor, not shown, and reciprocate in the front-rear direction. By reciprocating the traverse yarn guide 16a in a state where the yarn Y is hung, the yarn Y is wound around the corresponding bobbin B while traversing in the front-rear direction around the fulcrum yarn guide 18.
(Structure of interlacing device)
Next, the details of the scheduler 6 will be described. Fig. 2 is a perspective view showing the crosser 6. As shown in fig. 2, the crossroad apparatus 6 includes: a crossing section 20 for providing crossing to the yarn Y; a restricting section 40 disposed on both sides of the yarn running direction of the yarn winding section 20; a partition body 50 disposed between the crosswinding portion 20 and the regulating portion 40; and a base 60 that supports the entanglement 20, the restriction 40, and the separator 50.
Here, the "arrangement direction" shown in fig. 2 refers to a direction in which the plurality of threads Y are arranged. The "yarn running direction" refers to a running direction of the yarn Y, and is also a direction orthogonal to the arrangement direction in the present embodiment. The "height direction" refers to a direction in which the partition walls 51 of the partition body 50 stand up, and is a direction orthogonal to the arrangement direction and the running direction of the yarn. The height direction may coincide with the vertical direction, but may not coincide with the vertical direction.
(Trace crossing part)
The interlacing unit 20 is configured by arranging a plurality of interlacing members 21 extending in the yarn running direction in the arrangement direction. Fig. 3 is a cross-sectional view showing details of the crosswinding pieces 21, and shows a cross-section of the center in the running direction of the yarn for two crosswinding pieces 21 adjacent to each other in the arrangement direction.
The crosswind 21 has a yarn running space 22 formed therein and penetrating in the yarn running direction. The cross-sectional shape of the yarn running space 22 is an oblong shape having a long axis in the height direction, and the yarn Y runs in the yarn running direction at substantially the center thereof. Then, by ejecting the fluid toward the yarn running space 22, crossovers are given to the yarns Y running in the yarn running space 22.
In fig. 3, a yarn insertion space 24 connected to the yarn running space 22 in the arrangement direction is formed on the yarn insertion surface 23 corresponding to the left surface of the crosswinding sheet 21. The thread insertion space 24 is located at the center of the thread running space 22 in the height direction and is formed over the entire region of the interlacing sheet 21 in the thread running direction.
In fig. 3, a fluid ejection hole 26 is formed in a position substantially equal to the yarn insertion space 24 in the height direction on a fluid ejection surface 25 corresponding to the right side of the crosswinding sheet 21. The fluid ejection hole 26 is provided in the center of the crosswinding sheet 21 in the yarn running direction, and communicates with a fluid supply path 27 formed inside the crosswinding sheet 21.
Two interlace sheets 21 adjacent to each other in the arrangement direction are disposed in a state where the yarn insertion surface 23 of the right interlace sheet 21 is in contact with the fluid ejection surface 25 of the left interlace sheet 21 in fig. 3. By arranging in this way, the fluid ejection hole 26 of the left interlacing member 21 and the thread insertion space 24 of the right interlacing member 21 communicate with each other.
A fluid supply channel 61 is provided inside the base 60 that supports the interlace sheet 21, and a fluid supply port 62 is formed on one surface (upper surface) that supports the interlace sheet 21. The upper end of the fluid supply port 62 is connected to the fluid supply path 27 inside the interlace sheet 21, and the lower end of the fluid supply port 62 is connected to the fluid supply passage 61 inside the base 60.
Here, the portion of the yarn insertion surface 23 above the yarn insertion space 24 is slightly receded inward in the arrangement direction from the portion below the yarn insertion space 24. Therefore, in a state where the thread insertion surface 23 of the right interlacing member 21 and the fluid ejection surface 25 of the left interlacing member 21 are in contact with each other, a slit 28 is formed between two interlacing members 21 adjacent to each other above the thread insertion space 24. The yarn Y can be arranged in the yarn advancing space 22 through the slit 28 and the yarn insertion space 24.
The upper end portion of the interlace sheet 21 is formed with: a 1 st inclined surface 30 extending obliquely downward from the top 29 toward the yarn insertion surface 23; and a 2 nd inclined surface 31 extending obliquely downward from the top portion 29 toward the fluid ejection surface 25. As a result, an inverted triangular space is formed above the slit 28 by the two crossovers 21 adjacent to each other in the arrangement direction, and the yarn Y can be easily guided to the slit 28.
(regulating section)
Referring back to fig. 2, the restricting unit 40 will be described. The restricting portions 40 define the yarn paths of the plurality of yarns Y, and are provided on both sides of the interlacing portion 20 in the yarn running direction, in other words, on the upstream side and the downstream side in the yarn running direction. The restricting section 40 has a plurality of restricting guides 41 arranged in the arrangement direction. The restricting guide 41 is a columnar member extending in the height direction.
The yarn Y is passed between two restricting guides 41 adjacent to each other in the arrangement direction, thereby defining a yarn passage. More specifically, the yarn Y is configured to run substantially at the cross-sectional center of the yarn running space 22 by passing the yarn Y between two adjacent limiting guides 41 of one limiting section 40 and between two adjacent limiting guides 41 of the other limiting section 40 corresponding thereto. Although not shown, the regulating portion 40 is also provided with a vertical regulating portion for regulating the yarn Y in the vertical direction. The upper and lower restricting portions may be provided as a separate member from the restricting wire guide 41, or a part of the restricting wire guide 41 may function as the upper and lower restricting portions.
(partition body)
The partition body 50 has a plurality of partition walls 51 arranged in the arrangement direction, and the partition walls 51 block the fluid discharged from the yarn running space 22 and prevent the fluid from passing therethrough, thereby functioning as the "interference suppression mechanism" of the present invention. The specific structure of the separator 50 will be described with reference to fig. 4 and 5. Fig. 4 is a perspective view of the partition body 50, and fig. 5 is a plan view schematically showing the arrangement of the partition wall 51.
As shown in fig. 4, the partition body 50 is formed in a structure in which a plurality of partition walls 51 arrayed in the array direction are integrally supported by a bottom portion 52. Since the oil contained in the yarn Y may be scattered into the separator 50, it is preferable to use a material having oil resistance at least in a portion of the separator 50 where the scattered oil is likely to adhere, for example, a side surface of the partition wall 51 and an upper surface of the bottom portion 52.
Notched portions 52a are formed at both end corner portions of bottom portion 52 in the arrangement direction in partition body 50, and a part of bottom portion 52 other than notched portions 52a is formed with a convex portion 52b protruding in the downward direction. The convex portion 52b has a shape that can be fitted into a concave portion 63 (see fig. 6) formed on the surface of the base 60, which will be described later.
Next, the arrangement of the partition walls 51 will be described with reference to fig. 5. When a space in which the thread running space 22 formed in the crossweb 21 is extended in the thread running direction is defined as an extended space S (a region indicated by hatching), each partition wall 51 is disposed at the center of two extended spaces S adjacent to each other in the arrangement direction.
The partition wall 51 is provided over a range from the end surface of the crosswinding sheet 21 to the restricting guide 41 in the yarn running direction. In the height direction, as shown in fig. 2, the partition wall 51 is formed over a range from the upper surface of the bottom portion 52 to the upper end portion of the cross piece 21. That is, the partition wall 51 is provided over a range from a position below the lower end of the thread running space 22 to a position above the upper end of the thread running space 22 in the height direction, in other words, over a range that includes the formation range of the thread running space 22 and is wider than the formation range.
(base)
Fig. 6 is a perspective view of the base 60. As described above, the base 60 is a member that supports the intersection portion 20, the regulating portion 40, and the partition body 50, and has a substantially rectangular parallelepiped shape. Two recesses 63 capable of fitting into the projections 52b of the partition body 50 are formed on the upper surface of the base 60 supporting the interlaced part 20 and the like. The base body 60 is also provided with a fluid supply port 62, an attachment hole for attaching the restriction wire guide 41, and the like, but these are not shown.
The protruding portion 52b is fitted into the recessed portion 63, whereby the division body 50 can be positioned and attached to the base 60. On the other hand, the fitting between the convex portion 52b and the concave portion 63 is released by lifting the division body 50, and the division body 50 can be detached from the base 60. That is, the partition body 50 is detachably mounted to the base body 60.
(assignment of Cross-over)
In order to provide crossovers to the yarn Y running in the yarn running space 22, a fluid is supplied from a fluid supply device (not shown) to a fluid supply channel 61 (see fig. 3) of the base 60. As the fluid, for example, compressed air or the like is used. The fluid supplied to the fluid supply channel 61 is ejected from the fluid ejection hole 26 via the fluid supply port 62 and the fluid supply path 27, and the ejected fluid is supplied to the filament travel space 22 via the filament insertion space 24. That is, the fluid supply device, the fluid supply channel 61, the fluid supply port 62, the fluid supply channel 27, and the fluid ejection port 26 function as a "fluid supply portion" of the present invention.
Fig. 7 is a diagram schematically showing the flow of fluid. As shown by the arrows in fig. 7, the fluid ejected from the fluid supply unit into the yarn running space 22 is branched at both upper and lower sides to generate a swirling flow when it collides with the inner wall of the yarn running space 22. The yarn Y running in the yarn running space 22 is provided with crossovers by the flow of the fluid at this time. Subsequently, the fluid is separated toward the upstream side and the downstream side in the yarn running direction, and flows in the yarn running space 22 in parallel with the yarn Y.
The fluid flowing through the yarn running space 22 on the upstream side and the downstream side in the yarn running direction is discharged from the yarn running space 22 in a short time. At this time, if the fluids discharged from the respective yarn running spaces 22 arranged in the arrangement direction interfere with each other, the running of the yarn Y becomes unstable, and as a result, the yarn Y may be separated from the original yarn passage and not appropriately crosshatched. Therefore, in the present embodiment, the partition wall 51 is provided as an interference suppression means for suppressing interference between such fluids.
(Effect)
In the present embodiment, as shown in fig. 5, since the partition wall 51 is provided between two extension spaces S adjacent to each other in the arrangement direction, the fluid discharged from each of the filament running spaces 22 can be prevented from flowing into the adjacent extension space S, and therefore, the fluid discharged from each of the filament running spaces 22 can be prevented from interfering with each other. Therefore, the running of the yarn Y can be stabilized, and the interlacing performance can be improved. For example, according to the experiment conducted by the present applicant (using the FDY SD 83dtex/72f, set elongation 39.0%), the number of crossovers was increased from 15.0/m to 18.9/m by providing the partition wall 51, and the crosslinkability was improved by about 26%.
In the present embodiment, the plurality of partition walls 51 are provided on both the upstream side and the downstream side of the yarn running direction in the yarn winding section 20. Therefore, the running of the yarn Y can be stabilized both before the yarn Y enters the interlacing unit 20 and after the yarn Y exits from the interlacing unit 20, and thus the interlacing performance can be further improved.
In the present embodiment, as shown in fig. 5, the partition wall 51 is disposed at the center of two extension spaces S adjacent to each other in the arrangement direction. When the partition walls 51 are disposed at the centers of two elongated spaces S adjacent to each other in the arrangement direction, the filament passage is present substantially at the center of two partition walls 51 adjacent to each other in the arrangement direction, when viewed in a different manner. Therefore, the flow of the fluid acting from both sides in the arrangement direction can be substantially equalized with respect to the yarn Y running through the yarn passage, and the yarn Y can be effectively suppressed from swinging in the arrangement direction. As a result, the running of the yarn Y can be further stabilized, and the interlacing performance can be further improved.
In the present embodiment, the partition walls 51 are provided over a range that includes the formation range of the yarn running spaces 22 and is wider than the formation range in the height direction, and therefore, the fluid discharged from each yarn running space 22 can be more reliably prevented from passing over the partition walls 51 and entering the running space of the adjacent yarn Y. Therefore, the fluid discharged from each of the thread running spaces 22 can be effectively suppressed from interfering with each other. As a result, the running of the yarn Y can be further stabilized, and the interlacing performance can be further improved.
In the present embodiment, a partition body 50 having a plurality of partition walls 51 and a support portion (bottom portion) 52 that integrally supports the plurality of partition walls 51 is provided. By providing the plurality of partition walls 51 as a part of the partition body 50 integrally configured in this manner, the number of components can be reduced, and the installation of the plurality of partition walls 51 can be facilitated.
In the present embodiment, the fitting receiving portion (concave portion) 63 is formed in the base 60 that supports the winding portion 20, the fitting portion (convex portion) 52b that can be fitted to the fitting receiving portion 63 is formed in the partition body 50, and the partition body 50 is positioned with respect to the base 60 by fitting the fitting portion 52b to the fitting receiving portion 63. In this way, when the division body 50 is positioned with respect to the base body 60 by fitting between the fitting portion 52b formed on the division body 50 and the fitted portion 63 formed on the base body 60, the division body 50 can be positioned easily and with high accuracy.
In the present embodiment, the partition body 50 is detachable from the base body 60. In the interlacing unit 20, there are cases where maintenance is required such as yarn waste accumulating in the yarn running space 22. At this time, if the partition body 50 is detachable from the base body 60, the maintenance work of the interlace unit 20 can be easily performed by detaching the partition body 50 from the base body 60.
[ other embodiments ]
While the embodiments of the present invention have been described above, the embodiments to which the present invention can be applied are not limited to the above-described embodiments, and modifications can be appropriately made without departing from the spirit of the present invention as exemplified below.
For example, in the above embodiment, the partition wall 51 is provided as a member different from the sheet 21 constituting the sheet portion 20. However, the partition wall 51 may be provided integrally with the interlace sheet 21.
In the above embodiment, the plurality of partition walls 51 are provided as a part of the partition body 50 integrally configured, but the plurality of partition walls 51 may be provided as separate members.
In the above embodiment, the partition walls 51, that is, the partition bodies 50 are provided on both sides of the interlacing portion 20 in the yarn running direction. However, the plurality of partition walls 51 may be provided only on one side of the intersection 20.
In the above embodiment, the partition wall 51 is disposed at the center of the two elongated spaces S adjacent to each other in the arrangement direction, but may be disposed at a position other than the center.
In the above embodiment, the partition wall 51 is provided over the range from the end surface of the crosswinding sheet 21 to the restricting guide 41, but this need not be the case. For example, as long as the crosslinkability is not particularly affected, the partition wall 51 may be slightly separated from the end surface of the crosslinkability sheet 21, and the partition wall 51 may not be provided to the restricting guide 41.
In the above embodiment, the concave portion 63 is formed in the base 60 as the "fitted portion" of the present invention and the convex portion 52b is formed in the partition body 50 as the "fitting portion" of the present invention, however, the convex portion may be formed in the base 60 as the fitted portion and the concave portion may be formed in the partition body 50 as the fitting portion. The shapes and the number of the concave portions 63 and the convex portions 52b can be changed as appropriate.
In the above embodiment, the yarn Y runs between the plurality of restricting yarn guides 41 arranged in the arrangement direction, but the form of the yarn guide defining the yarn passage of the yarn Y is not limited to this. For example, a guide in which one or more yarn advancing portions for guiding the yarn Y are provided in one guide member, such as a U-shaped guide or a comb guide, may be used.
In the "interference suppressing mechanism" according to the present invention, a rectifying portion defined to flow the fluid discharged from the filament running spaces 22 in a predetermined direction may be provided instead of the partition wall 51 as in the above-described embodiment so as to suppress interference between the fluids discharged from the filament running spaces 22. For example, as such a rectifying portion, an inclined surface or a curved surface can be provided which allows the fluid discharged from each of the yarn running spaces 22 to escape upward (on the opposite side of the base 60). Such a rectifying portion may be provided together with the partition wall 51.
