Summary of the invention

Problems to be solved by the invention

As described above, in a false twist processing machine in which a plurality of twisting devices are arranged in a plurality of layers, for example, when a lower layer twisting device is used to twist a yarn, the yarn may pass through a position very close to an upper layer twisting device. At this time, if the rotating member (roller, disc, endless belt, etc.) of the upper layer twisting device is already rotating, the yarn is swung by the influence of the wind generated by the rotating member, and the yarn hanging work may become difficult or may fail. Further, if a yarn breakage occurs during the operation of the false twist texturing machine, the broken yarn may be wound around the rotating member.

Disclosure of Invention

The present invention has been made in view of the above problems, and an object thereof is to: in a false twist processing machine with a plurality of twisting devices arranged in a multi-layer manner, the first yarn hanging operation can be easily carried out, and the yarn is prevented from winding on a rotating component when the second yarn is broken.

Means for solving the problems

The invention relates to a false twist processing machine, which is provided with a plurality of twisting devices of a rotating component rotating when twisting yarn, wherein the twisting devices are arranged along a preset arrangement direction and are arranged in a plurality of layers, and is characterized in that: a partition member is provided between a yarn path of the yarn passing through a certain layer of the twisting device and the rotating member of the twisting device of the other layer adjacent to the yarn path.

According to the present invention, since the partition member is provided between the yarn path and the rotating member of the twisting device, the influence of wind generated by the rotation of the rotating member on the yarn can be suppressed. As a result, yarn hunting can be suppressed, and yarn hanging operation can be easily performed. Further, the presence of the partition member can suppress the yarn from being wound around the rotating member when the yarn is broken.

In the present invention, the plurality of twisting devices may be arranged in 2 layers of an upper layer and a lower layer.

By setting the number of layers of the twisting device to 2, the space in the vertical direction required for arranging the twisting device can be reduced.

In the present invention, the upper layer twisting devices and the lower layer twisting devices may be arranged in the arrangement direction in a staggered manner, the yarn twisted by the upper layer twisting devices may pass through the space between 2 lower layer twisting devices adjacent to each other, the yarn twisted by the lower layer twisting devices may pass through the space between 2 upper layer twisting devices adjacent to each other, and the partition member may be arranged between the 2 adjacent upper layer twisting devices and the lower layer twisting devices, respectively.

In the case where the yarn is configured to pass between the twisting devices, the distance between the yarn and the twisting devices becomes short, and yarn sway due to wind from the rotating member and yarn winding around the rotating member are likely to occur. Thus, the effect of providing the partition member is more remarkable.

In the present invention, the partition member may have a wall portion surrounding at least a part of the periphery of the yarn.

By surrounding the yarn with the wall portion in this manner, yarn fluttering and yarn entanglement on the rotating member due to wind from the rotating member can be more effectively suppressed.

In the present invention, the wall portion may have a shape that surrounds only a part of the periphery of the yarn.

If the wall portion is formed in a tubular shape surrounding the entire circumference of the yarn, the effect of suppressing the yarn from being swayed by the wind from the rotating member and the yarn from being entangled with the rotating member can be improved. If the wall portion is shaped to surround only a part of the periphery of the yarn, the yarn can be easily inserted into the inside of the wall portion by the opening portion where the wall portion is not formed.

In the present invention, the wall portion may extend across a range in which the rotating member is disposed in the yarn running direction.

By configuring the partition member in this manner, yarn sway caused by wind from the rotating member and yarn entanglement into the rotating member can be more effectively suppressed.

In the present invention, a yarn guide may be integrally formed in the partition member.

In order to define the yarn path, it is possible to provide yarn guides in the vicinity of the twisting device. If the yarn carrier is integrally formed on the partition member, the labor and time for setting the yarn carrier can be saved.

In the present invention, the yarn guide may be inserted into the partition member by insert molding.

By inserting the yarn carrier by insert molding, the separation member and the yarn carrier can be easily and reliably integrated even when they are made of different materials.

In the present invention, the partition member may have a flexible engaging portion engageable with an attached portion to which the partition member is attached, and the engaging portion may be deformable between an engaged state engageable with the attached portion and a released state released from engagement with the attached portion.

With such a configuration, the operator can easily attach and detach the partition member to and from the attached portion only by deforming the engaging portion.

In the present invention, the twisting device may be a needle twisting device as follows: the yarn twisting device includes a plurality of rollers as the rotating member and a cylindrical needle in contact with the peripheral surface of the plurality of rollers, and twists a yarn running inside the needle by rotating the plurality of rollers to rotate the needle.

ADVANTAGEOUS EFFECTS OF INVENTION

As will be described in detail later, in the case of the needle type twisting device, since the tension of the yarn is almost zero during the yarn hanging operation and the yarn is liable to swing, it is particularly effective to provide the partition member.

Detailed Description

(integral Structure of false twist processing machine)

Fig. 1 is an overall configuration diagram of a false twist processing machine 1 according to the present embodiment. As shown in fig. 1, the false twist processing machine 1 includes a yarn feeding section 2 for feeding a plurality of yarns Y, a processing section 3 for performing false twist processing on the plurality of yarns Y fed from the yarn feeding section 2, and a winding section 4 for winding the plurality of yarns Y false-twisted by the processing section 3 to form a plurality of packages P.

The yarn feeding section 2 has a creel 10 that holds a plurality of yarn feeding packages Q, and feeds a plurality of yarns Y to the processing section 3. The processing section 3 is configured by arranging a 1 st yarn feeding roller 11, a twist stop guide 12, a 1 st heating device 13, twisting devices 14(14A, 14B), a 2 nd yarn feeding roller 15, a doubling device 16, a 3 rd yarn feeding roller 17, a 2 nd heating device 18, and a 4 th yarn feeding roller 19 in this order from the upstream side in the yarn advancing direction along the yarn path. The winding section 4 winds the plurality of yarns Y false-twisted by the processing section 3 by the plurality of winding devices 20 to form a plurality of packages P.

In the false twist texturing machine 1, a plurality of yarns Y travel while being aligned in a direction perpendicular to the paper surface of fig. 1 (hereinafter referred to as an alignment direction). A plurality of devices 11-19 are arranged in the arrangement direction corresponding to the plurality of yarns Y. With such a configuration, the false twisting processing machine 1 can simultaneously false twist a plurality of yarns Y.

The false twist processing machine 1 has a main body 5 and a take-up table 6 which are disposed facing each other with a space therebetween in the left-right direction of fig. 1. The main body 5 and the winding table 6 extend in the arrangement direction. A support frame 7 is disposed across the upper part of the main body 5 and the upper part of the winding table 6. The devices 11 to 19 constituting the processing section 3 are mainly mounted on the main body 5 and the support frame 7. The yarn Y mainly runs around a working space 8 surrounded by the main body 5, the winding table 6, and the support frame 7. The operator performs various operations such as a yarn hanging operation in the working space 8.

(construction of processing section)

The structure of the processing section 3 will be explained. The 1 st yarn feeding roller 11 feeds the yarn Y supplied from the yarn supplying section 2 toward the 1 st heating device 13. The 1 st yarn feeding roller 11 is disposed below the support frame 7. The 1 st feed roller 11 has a drive roller and a driven roller, and conveys the yarn Y in a state where the yarn Y is sandwiched by the drive roller and the driven roller. The 2 nd feed roller 15, the 3 rd feed roller 17 and the 4 th feed roller 19 are also configured in the same manner.

The twist stop guide 12 prevents the twist applied to the yarn Y by the twisting device 14 from propagating upstream of the twist stop guide 12 in the yarn advancing direction. The yarn stop guide 12 is disposed between the 1 st yarn feeding roller 11 and the 1 st heating device 13 in the yarn running direction. The twist stop yarn guide 12 is attached to a shifter 22 that can move along a substantially vertically long guide rail 21. The shifter 22 is movable between a yarn hanging position (dashed line in fig. 1) near the 1 st feeding roller 11 and an operating position (solid line in fig. 1) directly above the 1 st heating device 13. The operator hangs the yarn on the yarn stop guide 12 while moving the shifter 22 to the yarn hanging position, and after the yarn hanging operation is completed, the shifter 22 is moved to the operating position. Therefore, when the false twist texturing machine 1 is in operation, the yarn carrier 12 is positioned directly above the 1 st heating device 13.

The 1 st heating device 13 heats the yarn Y twisted by the twisting device 14. The 1 st heating device 13 is disposed at the upper end of the main body 5 and extends in the vertical direction.

The twisting device 14 twists the yarn Y. The twisting device 14 is disposed in the main body 5 directly below the 1 st heating device 13. Therefore, the yarn path from the yarn stop guide 12 to the twisting device 14 through the 1 st heating device 13 is in the vertical direction. The twisting device 14 is arranged in upper and lower 2 layers. Hereinafter, the upper layer twisting device 14 is appropriately referred to as a twisting device 14A, and the lower layer twisting device 14 is appropriately referred to as a twisting device 14B. The twisting device 14 will be described in detail later.

The 2 nd feed roller 15 feeds the yarn Y twisted by the twisting device 14 toward the doubling device 16. The 2 nd yarn feeding roller 15 is disposed below the twisting device 14 in the main body 5. The feed speed of the 2 nd feed roller 15 for feeding the yarn Y is faster than the feed speed of the 1 st feed roller 11 for feeding the yarn Y. Accordingly, the yarn Y is drawn between the 1 st yarn feeding roller 11 and the 2 nd yarn feeding roller 15.

The doubling device 16 is a interlacing device (interlacing device) that performs doubling of 2 yarns Y by injecting air to the 2 yarns Y. As will be described in detail later, the yarn Y twisted by the upper layer twisting device 14A and the yarn Y twisted by the lower layer twisting device 14B are doubled by the doubling device 16. The yarn doubling device 16 is disposed below the 2 nd yarn supplying roller 15 in the main body 5.

The 3 rd feed roller 17 feeds the yarn Y doubled by the doubling device 16 toward the 2 nd heating device 18. The 3 rd feeding roller 17 is disposed below the doubling device 16 in the main body 5. The feed speed of the 3 rd feed roller 17 for feeding the yarn Y is slower than the feed speed of the 2 nd feed roller 15 for feeding the yarn Y. Therefore, the yarn Y is slackened between the 2 nd yarn feeding roller 15 and the 3 rd yarn feeding roller 17.

The 2 nd heating device 18 heats the yarn Y fed from the 3 rd yarn feeding roller 17. The 2 nd heating device 18 is disposed below the 3 rd yarn feeding roller 17 in the main body 5 and extends in the vertical direction.

The 4 th feeding roller 19 feeds the yarn Y heat-treated by the 2 nd heating device 18 toward the take-up device 20. The 4 th feed roller 19 is disposed in the vicinity of the lower portion of the winding table 6. The feeding speed of the 4 th feeding roller 19 for feeding the yarn Y is slower than that of the 3 rd feeding roller 17 for feeding the yarn Y. Therefore, the yarn Y is slackened between the 3 rd yarn feeding roller 17 and the 4 th yarn feeding roller 19.

In the processing section 3 configured as described above, the yarn Y drawn between the 1 st feed roller 11 and the 2 nd feed roller 15 is twisted by the twisting device 14. The twist applied by the twisting device 14 is prevented from propagating to the upstream side in the yarn advancing direction by the twist stop guide 12, and is heat-set by the 1 st heating device 13. The yarn Y in a relaxed state is treated by the doubling device 16 and the 2 nd heating device 18.

In the main body 5, a suction portion 23 is disposed below the 3 rd yarn feeding roller 17 and at a position facing the working space 8. The suction section 23 is used to temporarily hold the yarn Y during the yarn hanging operation.

(Structure of twisting device)

The structure of the twisting device 14 will be explained. As described above, the twisting device 14 has the upper layer twisting device 14A and the lower layer twisting device 14B, which are the same structure. Fig. 2 is a front view of the twisting device 14, in detail, a view of the twisting device 14 from the working space 8. Fig. 3 is a view of the twisting device 14 as viewed from above. The twisting device 14 is a needle twisting device that twists the yarn Y running inside the needle 41 by rotating the cylindrical needle 41 around the shaft.

The twisting device 14 has 2

rotating shafts

43, 44 extending in the vertical direction and arranged in the arrangement direction. The

rotary shafts

43 and 44 are rotatably supported by the base 42 via bearings, not shown. The rotating shaft 43 is fixed with upper and lower 2

rollers

45, 46. The upper and lower 2

rollers

47 and 48 are fixed to the rotary shaft 44. The

rollers

45 and 47 are disposed at the same position in the vertical direction and are separated from each other at one point without contact. The

rollers

46 and 48 are disposed at the same position in the vertical direction, and are separated from each other at one point without contact. The rotary shaft 43 is rotationally driven around the shaft by a motor 54.

The needle 41 is a cylindrical member extending in the vertical direction, and the yarn Y runs inside the needle 41. A large-diameter magnetic portion 41a is formed in the middle portion of the needle 41 so as to face the

magnets

49 and 50 described later. A hook 41b extending in a direction orthogonal to the axial direction is fixed to the lower end portion (the end portion on the downstream side in the yarn running direction) of the needle 41. The yarn Y is wound around the winding portion 41b for 1 turn. Thus, when the needle 41 rotates around the shaft, the yarn Y is twisted.

The

magnets

49 and 50 are fixed to the base 42 via a bracket 51. The magnet 49 is disposed between the

rollers

45 and 46. The magnet 50 is disposed between the

rollers

47 and 48. The needle 41 is inserted between the rollers 45 and 47 (between the rollers 46 and 48) with the magnetic portion 41a of the needle 41 facing the

magnets

49 and 50. The needles 41 are held by the

magnets

49 and 50 in contact with the peripheral surfaces of the rollers 45 to 48. The needle 41 is not fixed to another member, but is held by the magnetic force of the

magnets

49, 50.

A ring-shaped guide member 52 is disposed directly above the needle 41. The guide member 52 is fixed to the base 42 via a bracket, not shown. A tubular guide member 53 extending in the vertical direction is disposed immediately below the needle 41. The guide member 53 is fixed to the base 42.

When the rotary shaft 43 is rotated in the direction indicated by the arrow in fig. 3 by the motor 54, the

rollers

45, 46 fixed to the rotary shaft 43 rotate in the same direction. Then, the needles 41 in contact with the peripheral surfaces of the

rollers

45 and 46 are driven to rotate in the direction opposite to the rotation direction of the

rollers

45 and 46 by the frictional force. Further, the

rollers

47 and 48 in contact with the circumferential surface of the needle 41 are driven to rotate in the direction opposite to the rotational direction of the needle 41 by the frictional force. The yarn Y running inside the needle 41 is twisted by the needle 41 rotating while being sandwiched between the

rollers

45 and 46 and the

rollers

47 and 48.

(configuration of twisting device)

The configuration of the twisting device 14 will be explained. Fig. 4 is a view of the upper layer twisting device 14A and the lower layer twisting device 14B as viewed from the working space 8. Fig. 5a is a view of the upper layer twisting device 14A as viewed from above, and fig. 5B is a view of the lower layer twisting device 14B as viewed from above. The diagrams a and b in fig. 5 match the positions in the arrangement direction. A direction orthogonal to both the vertical direction and the arrangement direction is defined as a depth direction, a side of the working space 8 in the depth direction is defined as a near side, and a side opposite to the near side is defined as a rear side.

In the false twist processing machine 1 of the present embodiment, for example, the yarn Y to which S twist is applied by the upper layer twisting device 14A and the yarn Y to which Z twist is applied by the lower layer twisting device 14B on the lower left side are doubled by the doubling device 16 to become 1 yarn. Therefore, the number of the twisting devices 14 is 2 times as large as that of the winding device 20, and if the twisting devices 14 are arranged in a row in the arrangement direction, the size of the false twist texturing machine 1 in the arrangement direction becomes large. Therefore, by dividing the twisting device 14 into 2 layers of the upper layer and the lower layer, the upper layer twisting device 14A and the lower layer twisting device 14B are partially overlapped in the arrangement direction, and the twisting devices 14 are arranged at high density in the arrangement direction. This suppresses the increase in the dimension of the false twist processing machine 1 in the arrangement direction.

The upper twist devices 14A are fixed to the support member 25 in a state of being arranged at equal intervals (pitch a) in the arrangement direction. The lower layer twisting devices 14B are also fixed to the support member 26 in a state of being arranged at equal intervals (pitch a) in the arrangement direction. The upper layer twisting device 14A and the lower layer twisting device 14B are arranged with a half pitch (a/2) offset in the arrangement direction, and staggered in the arrangement direction. The upper layer twisting device 14A and the lower layer twisting device 14B are arranged at the same position in the depth direction.

The upper layer twisting device 14A is disposed at the center of 2 lower layer twisting devices 14B adjacent to each other in the arrangement direction. The lower layer twisting device 14B is disposed at the center of 2 upper layer twisting devices 14A adjacent to each other in the arrangement direction. Accordingly, the yarn Y twisted by the upper layer twisting device 14A passes between 2 lower layer twisting devices 14B adjacent to each other. And, the yarn Y twisted by the lower layer twisting device 14B passes between 2 upper layer twisting devices 14A adjacent to each other. That is, the yarn Y passes through a narrow space (for example, 50mm or less) between 2 twisting devices 14 adjacent to each other in the arrangement direction.

(yarn swing during hanging operation to twisting device)

The yarn hanging operation of the 2 yarns Y doubled by the doubling device 16 to the twisting device 14 is performed simultaneously. That is, in fig. 4, the yarn hooking operation of the set of the upper layer twisting device 14A and the lower layer twisting device 14B located at the lower left thereof is performed simultaneously. Alternatively, the yarn Y over-twisted by the upper layer twisting device 14A may be doubled with the yarn Y over-twisted by the lower layer twisting device 14B on the right lower side. In this case, the yarn hanging operation of the set of the upper layer twisting device 14A and the lower layer twisting device 14B located right below it is performed simultaneously. After the yarn hanging operation to a certain pair of twisting

devices

14A and 14B is completed, the yarn Y is sucked and held by the suction part 23, and then the

twisting devices

14A and 14B are operated. Subsequently, the operation of hanging the yarn to the

twisters

14A and 14B of the right adjacent group is performed. Further, the yarn winding operation may be performed sequentially from the pair of twisting

devices

14A and 14B on the right side.

In the case where the yarn hanging work is performed in this order, when the yarn hanging work is performed on a certain group of twisting

devices

14A and 14B, the

twisting devices

14A and 14B of the adjacent group on the left side thereof are already in an operating state. Therefore, the yarn Y in the yarn hanging operation to the upper layer twisting device 14A (or the lower layer twisting device 14B) may be swung by wind generated by the rotation of the rollers 45 to 48 of the lower layer twisting device 14B (or the upper layer twisting device 14A) adjacent to the left side thereof.

In particular, in the needle twist device 14, the yarn oscillation tends to become large for the following reason. That is, the suction force of the suction part 23 hardly reaches the upstream side in the yarn running direction from the end of the yarn hooking operation to the twisting device 14 to the operation of the twisting device 14, compared with the winding part 41b of the needle 41. Therefore, the tension of the yarn Y on the upstream side of the twisting device 14 during the yarn hanging operation is almost zero, and the yarn Y is likely to swing under the influence of wind. When the lower layer twister 14B is twisted, the yarn Y on the upstream side of the twister 14B passes between the upper 2 twisters 14A, and therefore the problem of yarn sway is particularly remarkable.

The yarn swing may cause problems such as difficulty in the yarn hanging work, failure in the yarn hanging work, and winding of the yarn Y in the yarn hanging work around the rotating rollers 45 to 48. Such a problem may occur not only when the first yarn-hanging operation for preparing the operation of the false twist processing machine 1 is performed, but also when the yarn Y is hung with the operation of the false twist processing machine 1 interrupted. Further, if yarn breakage occurs during the operation of the false twist texturing machine 1, there is another problem that the broken yarn Y may be wound around the rotating rollers 45 to 48.

(partition member)

In the present embodiment, in order to solve the above-described problem, the partition member 60 is provided. As shown in fig. 4 and 5, the partition member 60 is disposed in the upper and lower layers at intermediate positions of 2 twisting devices 14 adjacent to each other in the arrangement direction, respectively.

Fig. 6 is a perspective view of the partition member 60. Fig. 7 is a cross-sectional view of the partition member 60 taken along a horizontal plane, and in detail, a cross-sectional view taken along a horizontal plane passing through a yarn guide 62 described later. Fig. 8 is a sectional view of the partition member 60 taken along a vertical plane, in detail on the plane viii-viii of fig. 7. Fig. 8 shows a state in which the partition member 60 is attached to the upper support member 25, but it is also attached to the lower support member 26 in the same manner.

As shown in fig. 6, the partition member 60 includes a main body 61 made of resin and a yarn guide 62 made of ceramic insert-molded to the main body 61. The main body 61 is integrally formed with a wall 63, a carrier support portion 64, an engagement portion 65, and a pressing portion 66 by resin molding.

The wall portion 63 extends along the yarn running direction (approximately in line with the vertical direction in the present embodiment). In the yarn running direction, the wall 63 extends at least over the range of the twisting device 14 where the rollers 45 to 48 are arranged, that is, at least over the range from the upper end of the roller 45(47) to the lower end of the rollers 46 (48). The wall 63 has a U-shaped cross section perpendicular to the yarn running direction. The partition member 60 is disposed so that a part of the periphery of the yarn Y is surrounded by the wall portion 63. In other words, the wall 63 of the partition member 60 is disposed between the yarn path of the yarn Y passing through the upper layer twisting device 14A (or the lower layer twisting device 14B) and the rollers 45 to 48 of the lower layer twisting device 14B (or the upper layer twisting device) closest to the yarn path.

The portion where wall 63 is not formed is an opening 67. The opening 67 faces the working space 8, and the operator can easily thread the yarn guide 62 from the working space 8 through the opening 67.

The carrier support portion 64 is formed at the lower end of the wall portion 63 and inside the wall portion 63, and is a portion into which the carrier 62 is fitted. As shown in fig. 7, the carrier support portion 64 is C-shaped when viewed from above, and has an inlet 64 a. The introduction port 64a functions as a passage for introducing the yarn Y inserted from the opening 67 into the yarn guide 62.

As shown in fig. 8, the engaging portion 65 protrudes below the lower end of the wall portion 63 and can be engaged with the mounting hole 25a formed in the support member 25. The engaging portion 65 has a U-shaped cross section perpendicular to the vertical direction and is flexible. On the outer peripheral surface of the engaging portion 65, 2 hook portions 65a are formed at positions facing each other in the arrangement direction. In a state where no urging force is applied to the hook portion 65a, the hook portion 65a protrudes outward beyond the edge of the mounting hole 25a, and the engagement portion 65 and the mounting hole 25a are in an engaged state. On the other hand, in a state where the hook portion 65a is pushed inward, the engagement portion 65 is deformed to become a released state in which the engagement with the mounting hole 25a is released.

When the partition member 60 is mounted in the mounting hole 25a, the operator pushes the engaging portion 65 into the mounting hole 25a from above. Then, the inclined portion 65b of the hook portion 65a is pushed by the edge of the mounting hole 25a, and the engagement portion 65 is deformed and inserted into the mounting hole 25 a. When the engaging portion 65 returns to the original shape, the hook portion 65a protrudes outward beyond the edge of the mounting hole 25a, and becomes engaged. When removing the partition member 60 from the mounting hole 25a, the operator may push the 2 hook portions 65a inward. Then, the engaging portion 65 is released, and the partition member 60 can be pulled out upward from the mounting hole 25 a. The attachment hole 25a is connected to a notch 25b (see fig. 5) formed in the depth direction from the near side of the support member 25. During the yarn hooking operation to the partition member 60, the yarn Y is inserted from the notch 25b by the operator standing in the operation space 8.

As shown in fig. 8, 2 pressing portions 66 are formed at positions facing each other in the arrangement direction, and protrude outward from the outer peripheral surface of the lower end portion of the wall portion 63. The pressing portion 66 has a shape bent downward. Therefore, when the partition member 60 is attached to the attachment hole 25a, the partition member 60 is biased upward by the pressing portion 66. As a result, the hook 65a is pressed by the lower surface of the support member 25, and the looseness of the partition member 60 can be suppressed.

As shown in fig. 7, the yarn guide 62 is C-shaped when viewed from above, and has an inlet 62 a. The inlet 62a of the yarn guide 62 communicates with the inlet 64a of the yarn guide support 64. The yarn Y is hooked on the yarn guide 62 through the

introduction ports

64a and 62 a. The yarn carrier 62 is disposed inside the wall portion 63, i.e., on the back side of the near-end of the wall portion 63. Therefore, by hooking the yarn Y to the carrier 62, the yarn Y can be reliably arranged inside the wall portion 63.

For example, when the yarn hooking operation is performed for the lower layer twisting device 14B, the yarn Y is passed through the yarn guide 62 of the partition member 60 located immediately above the twisting device 14B, and then the yarn hooking operation is performed. In this case, even if wind is generated by the rotation of the rollers 45 to 48 of the upper layer twisting device 14A adjacent to the yarn path of the yarn Y, the wall 63 of the partition member 60 can suppress the wind from reaching the yarn Y. Even if the wind enters the inside of the wall 63 from the opening 67, the yarn Y is caught by the yarn guide 62, and therefore, the yarn swing that hinders the yarn catching operation can be avoided. Further, the presence of the wall 63 can prevent the yarn Y from being wound around the rollers 45 to 48 during yarn breakage.

(Effect)

In the false twist processing machine 1 of the present embodiment, a plurality of twisting devices 14 having rollers 45 to 48 (corresponding to a rotating member of the present invention) rotating when twisting a yarn Y are arranged in a predetermined arrangement direction and arranged in multiple stages. Further, a partition member 60 is provided between the yarn path of the yarn Y passing through the twisting device 14 of a certain layer and the rollers 45 to 48 of the twisting devices 14 of other layers adjacent to the yarn path. Therefore, the influence of wind waves and the yarn Y generated by the rotation of the rollers 45 to 48 can be suppressed. As a result, yarn hunting can be suppressed, and yarn hanging operation can be easily performed. Further, since the partition member 60 is present, the yarn Y can be prevented from being wound around the rollers 45 to 48 at the time of yarn breakage.

In the present embodiment, the plurality of twisting devices 14 are disposed in 2 layers of an upper layer and a lower layer. By setting the number of layers of the twisting device 14 to 2, the space in the vertical direction required for disposing the twisting device 14 can be reduced.

In the present embodiment, the upper layer twisting devices 14A and the lower layer twisting devices 14B are arranged alternately in the arrangement direction, the yarn Y twisted by the upper layer twisting device 14A passes between 2 lower layer twisting devices 14B adjacent to each other, the yarn Y twisted by the lower layer twisting device 14B passes between 2 upper layer twisting devices 14A adjacent to each other, and the partition member 60 is arranged between the 2 twisting devices 14 adjacent to each other in the upper layer and the lower layer, respectively. In the case where the yarn Y is configured to pass between the twisting devices 14, the distance between the yarn Y and the twisting devices 14 becomes short, and yarn sway due to wind from the rollers 45 to 48 and winding of the yarn Y around the rollers 45 to 48 are likely to occur. Thus, the effect of providing the partition member 60 is more remarkable.

In the present embodiment, the partition member 60 has a wall portion 63 surrounding at least a part of the periphery of the yarn Y. By surrounding the yarn Y with the wall 63 in this way, yarn sway caused by wind from the rollers 45 to 48 and winding of the yarn Y around the rollers 45 to 48 can be more effectively suppressed.

In the present embodiment, the wall 63 has a shape that surrounds only a part of the periphery of the yarn Y. If the wall 63 is formed in a tubular shape surrounding the entire circumference of the yarn Y, the effect of suppressing the yarn Y from being wound around the rollers 45 to 48 by the yarn Y being swayed by the wind from the rollers 45 to 48 can be enhanced, but it is troublesome to thread the yarn Y inside the tubular wall 63. If the wall 63 is shaped to surround only a part of the periphery of the yarn Y, the yarn Y can be easily inserted into the wall 63 through the opening 67 where the wall 63 is not formed.

In the present embodiment, the wall 63 extends across the range where the rollers 45 to 48 are arranged in the yarn running direction. By configuring the partition member 60 in this way, the yarn sway caused by the wind from the rollers 45 to 48 and the winding of the yarn Y around the rollers 45 to 48 can be more effectively suppressed.

In the present embodiment, the yarn carrier 62 is integrally formed on the partition member 60. In order to define the yarn path, it is possible to provide a yarn guide 62 near the twisting device 14. If the yarn carrier 62 is integrally formed on the partition member 60, the labor and time for providing the yarn carrier 62 can be saved.

In the present embodiment, the partition member 60 is a member into which the yarn carrier 62 is fitted by insert molding. By inserting the yarn carrier 62 by insert molding, even when the partition member 60 and the yarn carrier 62 are formed of different materials, they can be easily and reliably integrated.

In the present embodiment, the partition member 60 has a flexible engaging portion 65 engageable with the mounting hole 25a (corresponding to the mounted portion of the present invention) of the mounting partition member 60, and the engaging portion 65 is deformable between an engaged state engageable with the mounting hole 25a and a released state released from engagement with the mounting hole 25 a. With such a configuration, the operator can easily attach and detach the partition member 60 to and from the attachment hole 25a by simply deforming the engagement portion 65.

In the present embodiment, the twisting device 14 is a needle twisting device 14 having rollers 45 to 48 and cylindrical needles 41 in contact with the circumferential surfaces of the rollers 45 to 48, and twisting the yarn Y running inside the needles 41 by rotating the rollers 45 to 48 to rotate the needles 41. As described above, in the case of the needle twist device 14, since the tension of the yarn Y is almost zero during the yarn hanging operation and the yarn sway is likely to occur, it is particularly effective to provide the partition member 60.

(other embodiments)

A modification to the above embodiment will be described.

In the above embodiment, a case where the present invention is applied to the false twist working machine 1 having the needle twisting device 14 is explained. However, the invention can also be applied to a false twist processing machine having a friction type or belt type twisting device. In the friction type twisting device, the yarn travels while contacting the circumferential surfaces of the plurality of spirally arranged disks, and the plurality of disks are rotated to twist the yarn. In this case, the plurality of disks correspond to the rotating member of the present invention. The belt twisting device twists the yarn by sandwiching the yarn by 2 endless belts, rotating each endless belt. In this case, 2 endless belts correspond to the rotating member of the present invention.

In the above embodiment, the plurality of twisting devices 14 are arranged in 2 layers of the upper layer and the lower layer. However, the plurality of twisting devices 14 may be arranged in 3 or more layers.

In the above embodiment, the upper layer twisting device 14A and the lower layer twisting device 14B are arranged at the same position in the depth direction and are arranged alternately in the array direction. However, the upper layer twisting device 14A and the lower layer twisting device 14B may be disposed at different positions in the depth direction. In this case, if the yarn path passing through the upper layer twisting device 14A and the yarn path passing through the lower layer twisting device 14B can be shifted in the depth direction to avoid interference of the yarn Y, the upper layer twisting device 14A and the lower layer twisting device 14B may be arranged at the same position in the arrangement direction.

The specific structure of the partition member 60 is not limited to the form described in the above embodiment. For example, a plate-like member substantially perpendicular to the horizontal plane may be disposed between the yarn Y and the twisting device 14 closest to the yarn Y, and the plate-like member may be used as the partition member. Alternatively, the wall 63 of the partition member 60 may be cylindrical. The partition member 60 may be fixed to the

support members

25 and 26 by using bolts or the like.

In the above embodiment, the yarn carrier 62 is integrally formed in the partition member 60 by insert molding. However, the yarn carrier 62 may be integrally obtained by a method other than insert molding. Further, the yarn guide may be provided separately from the partition member.

The specific structure of the yarn guide 62 is not limited to the embodiment described above. That is, the yarn guide 62 is not limited to the C-shaped configuration, and may be a tubular, vortex, dock, hook, or the like. The shape of the carrier support portion 64 may be appropriately changed according to the specific shape of the carrier 62.

In the false twist texturing machine 1 of the above embodiment, 2 yarns Y are doubled to produce 1 yarn Y, but doubling is not essential.
