Description

Silk thread processing device

Technical Field

The present invention relates to a yarn processing device for performing a predetermined process on a yarn.

Background

Conventionally, a spinning production facility configured to take up a plurality of filaments spun from a spinning device by a take-up device is known. For example, patent document 1 discloses a spinning production facility (a spinning winding device of patent document 1) including a spinning device that spins a plurality of filaments downward, and a yarn feeding roller that is disposed below the spinning device and that conveys the plurality of filaments.

In such a spinning production facility, a yarn processing device having a yarn processing section such as a moving nozzle may be disposed in a yarn path between the spinning device and the yarn feeding roller. The moving nozzle is a device for applying bundling property to the yarn by using a jet action of compressed air. The moving nozzle has the same configuration as that of the interlacing unit of the interlacing device described in patent document 2, for example. The moving nozzle is formed with a plurality of wire traveling spaces extending along a wire traveling direction. The yarn running spaces are arranged at a predetermined pitch in the direction of arrangement of the plurality of yarns. The moving nozzle performs a process of applying bundling to a plurality of threads disposed in each thread traveling space.

Patent document 2: japanese patent laid-open No. 2019-105007

The plurality of filaments spun from the spinning device are disposed in the plurality of filament traveling spaces in a state of being collected in a collecting part for collecting the plurality of filaments, such as a suction gun. However, the pitch of the plurality of wires in the arrangement direction gradually narrows toward the converging portion, and the plurality of wires must be arranged in the wire travel space in a state in which the pitch of the plurality of wires in the arrangement direction is different on the upstream side and the downstream side in the wire travel direction. Thus, the following problems arise.

As described above, the pitch of the plurality of wires gradually narrows toward the converging portion, and therefore the pitch of the plurality of wires in the arrangement direction differs on the upstream side and downstream side in the wire traveling direction. On the other hand, the yarn running spaces extending along the yarn running direction are arranged at a predetermined pitch in the arrangement direction. Therefore, even if the position of the converging portion is adjusted, for example, the pitch of the plurality of wires is made to coincide with the pitch of the upstream ends of the plurality of wire travel spaces in the wire travel direction, there is a case where the pitch of the downstream ends of the plurality of wire travel spaces is not made to coincide with each other. Accordingly, a plurality of wires having different pitches in the arrangement direction on the upstream side and the downstream side in the wire traveling direction cannot be appropriately arranged in each wire traveling space. Therefore, in the current situation, when a plurality of wires having different pitches in the arrangement direction between the upstream side and the downstream side in the wire traveling direction are arranged in each wire traveling space, an operator needs to arrange the wires one at a time in each wire traveling space, which is a problem in that time is required.

Such a problem occurs not only in a yarn processing device having a moving nozzle as a yarn processing section, but also in a yarn processing device described below. That is, the same problem occurs in a yarn processing device (for example, an oil nozzle that applies oil to a plurality of yarns, a tension sensor that detects tension of a plurality of yarns, and the like) that performs a predetermined process on a plurality of yarns traveling in a plurality of yarn traveling spaces that are aligned at a predetermined pitch in an alignment direction.

Disclosure of Invention

The present invention is to easily arrange a plurality of wires having different pitches on the upstream side and the downstream side in the wire traveling direction in a plurality of wire traveling spaces formed in a wire processing unit.

The yarn processing device of the present invention is characterized by comprising: a yarn processing unit having a plurality of yarn running spaces extending in a yarn running direction and arranged at predetermined intervals in an arrangement direction intersecting the yarn running direction, and performing predetermined processing on a plurality of yarns running in the plurality of yarn running spaces; and a yarn arrangement unit for arranging a plurality of yarns in the plurality of yarn travel spaces, the yarn arrangement unit including: a 1 st holding portion having a plurality of 1 st holding grooves aligned in the alignment direction; and a 2 nd holding portion which is disposed downstream of the 1 st holding portion in the yarn running direction and holds the plurality of yarns while maintaining a pitch of the plurality of yarns held by the 1 st holding grooves, wherein the 1 st holding portion is capable of obtaining a 1 st yarn hanging position at which the 1 st holding portion is caught by the plurality of yarns and a 1 st yarn arrangement completion position at which the arrangement of the plurality of yarns in the yarn running direction is completed at a position upstream of the yarn running space in the yarn running direction, and wherein the 2 nd holding portion is capable of obtaining a 2 nd yarn hanging position at which the 2 nd holding portion is caught by the plurality of yarns and a 2 nd arrangement completion position at which the arrangement of the plurality of yarns in the yarn running space is completed at a position downstream of the yarn running direction in the yarn running space, and wherein the 1 st holding portion at the 1 st yarn hanging position and the 2 nd holding portion at the 2 nd yarn hanging position are adjacent to each other in the yarn running direction.

It is difficult to arrange a plurality of wires having different pitches in the arrangement direction on the upstream side and the downstream side in the wire traveling direction in a plurality of wire traveling spaces extending along the wire traveling direction and arranged at a predetermined pitch in the arrangement direction. In the present invention, since the 1 st holding portion at the 1 st yarn-hanging position and the 2 nd holding portion at the 2 nd yarn-hanging position are adjacent to each other in the yarn traveling direction, a plurality of yarns can be collectively caught at the same interval in the arrangement direction with respect to the 1 st holding portion and the 2 nd holding portion. Then, the 1 st holding portion having the plurality of wires hooked thereon obtains the 1 st arrangement completion position, and the 2 nd holding portion having the plurality of wires hooked thereon obtains the 2 nd arrangement completion position, whereby the plurality of wires can be arranged in the plurality of wire travel spaces in a state where the pitch in the arrangement direction of the plurality of wires and the plurality of wire travel spaces is identical. Therefore, a plurality of wires having different upstream-side and downstream-side pitches in the wire traveling direction can be easily arranged in the plurality of wire traveling spaces arranged at a predetermined pitch in the arrangement direction.

The yarn processing device according to the present invention preferably further comprises: a 1 st limit yarn guide having a plurality of 1 st groove portions having the same pitch in the arrangement direction as the plurality of 1 st holding grooves, the 1 st limit yarn guide being disposed upstream of the yarn travel space in the yarn travel direction and capable of disposing a plurality of yarns caught by the 1 st groove portions in the plurality of yarn travel spaces; and a 2 nd restriction yarn guide having a plurality of 2 nd groove portions having the same pitch as the plurality of 1 st groove portions in the arrangement direction, the 2 nd restriction yarn guide being disposed downstream of the yarn advancing space in the yarn advancing direction and being capable of disposing the plurality of yarns caught in the plurality of 2 nd groove portions in the plurality of yarn advancing space, the 1 st disposition completion position being a position at which the 1 st holding portion withdraws from a yarn path when the plurality of yarns are caught by the 1 st restriction yarn guide and the 2 nd restriction yarn guide, the 2 nd disposition completion position being a position at which the 2 nd holding portion withdraws from a yarn path when the plurality of yarns are caught by the 1 st restriction yarn guide and the 2 nd restriction yarn guide, the 1 st holding portion being connected to the 1 st restriction yarn guide in the middle of moving from the 1 st disposition completion position to the 1 st disposition completion position, the 2 nd holding portion being connected to the 2 nd restriction yarn guide in the middle of moving from the 2 nd disposition completion position to the 2 nd restriction yarn guide.

The following constitution exists: the plurality of wires are placed in the plurality of wire travel spaces by hooking the plurality of wires to a 1 st restriction wire guide placed on the upstream side of the wire travel space in the wire travel direction and a 2 nd restriction wire guide placed on the downstream side. In such a configuration, when a plurality of wires having different pitches on the upstream side and the downstream side in the wire traveling direction are to be hooked on the 1 st limit wire guide and the 2 nd limit wire guide, the following problems occur. That is, even if the pitch of the plurality of wires is made to coincide with the pitch of one of the 1 st limit guide and the 2 nd limit guide, the pitch of the plurality of wires differs between the upstream side and the downstream side in the wire traveling direction, and thus the pitch of the other limit guide does not coincide with the pitch of the other limit guide. Therefore, it is difficult to intensively hook a plurality of wires having different pitches on the upstream side and the downstream side in the wire traveling direction on the 1 st limit wire guide disposed on the upstream side of the wire traveling space and the 2 nd limit wire guide disposed on the downstream side. In the present invention, after the plurality of wires are collectively hooked to the 1 st holding portion at the 1 st thread-hanging position and the 2 nd holding portion at the 2 nd thread-hanging position, the 1 st holding portion is moved to the 1 st arrangement completion position, and the 2 nd holding portion is moved to the 2 nd arrangement completion position, whereby the plurality of wires are easily collectively hooked to the 1 st limit thread guide and the 2 nd limit thread guide. As a result, a plurality of wires having different upstream-side and downstream-side pitches in the wire traveling direction can be easily arranged in the plurality of wire traveling spaces arranged at a predetermined pitch in the arrangement direction.

In the yarn processing device according to the present invention, it is preferable that the 2 nd holding portion has a plurality of 2 nd holding grooves having the same pitch in the arrangement direction as the plurality of 2 nd groove portions.

According to the present invention, since the pitch of the plurality of wires hooked to the 2 nd holding groove of the 2 nd holding portion is the same as the pitch in the arrangement direction of the plurality of 2 nd groove portions, the plurality of wires can be reliably delivered to the corresponding 2 nd groove portions, respectively. Thus, the 2 nd limiting yarn guide can be accurately fed, and the plurality of yarns can be accurately arranged in the plurality of yarn running spaces aligned in the alignment direction.

In the yarn processing device according to the present invention, the 2 nd holding portion is preferably a rotating roller rotatable about a rotation axis along the arrangement direction.

According to the present invention, the plurality of wires hooked to the 2 nd holding portion of the rotating roller are brought into contact with the circumferential surface of the rotating roller in an orthogonal manner by friction force between the circumferential surface of the rotating roller and each wire. Therefore, the pitch of the plurality of wires hooked to the 2 nd holding portion matches the pitch of the plurality of wires hooked to the 1 st groove portion of the 1 st holding portion disposed upstream of the 2 nd holding portion in the wire traveling direction. Further, even if the pitch of the plurality of wires traveling downstream of the 2 nd holding portion in the wire traveling direction is different from the pitch of the wires on the 2 nd holding portion, the pitch of the plurality of wires caught by the 2 nd holding portion can be maintained without being shifted by the frictional force between the circumferential surface of the rotating roller and each wire. Therefore, the pitch of the plurality of wires hooked to the 2 nd holding portion is the same as the pitch of the plurality of 1 st holding grooves in the arrangement direction, and further the pitch of the plurality of 1 st groove portions and the plurality of 2 nd groove portions in the arrangement direction. Therefore, the plurality of wires can be more reliably delivered to the corresponding 2 nd groove portions. Thus, the 2 nd restriction yarn guide can be accurately fed, and the plurality of yarns can be accurately arranged in the plurality of yarn travel spaces aligned in the alignment direction.

In the yarn processing device according to the present invention, it is preferable that the yarn arranging section has a linking mechanism for linking movement of the 1 st holding section between the 1 st yarn hanging position and the 1 st arrangement completion position and movement of the 2 nd holding section between the 2 nd yarn hanging position and the 2 nd arrangement completion position.

When the wire is transferred from only one holding portion to the limiting guide, the wire may be lifted from the limiting guide after the wire is transferred from the other holding portion to the limiting guide, and may be separated from the limiting guide after the wire is transferred from the other holding portion. According to the present invention, the wire can be transferred from the 1 st holding portion to the 1 st limit wire guide and the wire can be transferred from the 2 nd holding portion to the 2 nd limit wire guide at the same timing. Therefore, the threading operation to the two restriction guides can be performed more reliably.

In the yarn processing device according to the present invention, the interlocking mechanism preferably includes: a 1 st swing arm rotatable about a 1 st swing axis extending along the arrangement direction, the 1 st holding portion being swingably supported; and a 2 nd swing arm rotatable about a 2 nd swing axis extending along the arrangement direction, the 2 nd holding portion being swingably supported, the 1 st swing arm including a 1 st gear, the 2 nd swing arm including a 2 nd gear, the interlocking mechanism interlocking the 1 st swing arm and the 2 nd swing arm by meshing the 1 st gear and the 2 nd gear, and thereby interlocking movement of the 1 st holding portion and movement of the 2 nd holding portion.

According to the present invention, the 1 st swing arm and the 2 nd swing arm are rotated in conjunction with each other by meshing the 1 st gear and the 2 nd gear, whereby the 1 st holding portion and the 2 nd holding portion can be swung in conjunction with each other. Therefore, complicated configuration and control are not required to move the 1 st holding portion and the 2 nd holding portion in conjunction with each other.

In the yarn processing device according to the present invention, the 1 st yarn hanging position is preferably the following position: when viewed from the arrangement direction, the 1 st holding portion is located at a position offset from a yarn path in which a plurality of yarns are caught by the 1 st limit yarn guide and the 2 nd limit yarn guide in an opening direction of the 1 st slot portion opening, and the 2 nd yarn catching position is the following position: the 2 nd holding portion is offset from a thread path in which the plurality of threads are caught by the 1 st limit thread guide and the 2 nd limit thread guide in an opening direction of the 2 nd slot portion opening, when viewed from the arrangement direction.

According to the present invention, when a plurality of wires are caught by the 1 st holding portion located at the 1 st yarn hanging position and the 2 nd holding portion located at the 2 nd yarn hanging position, the wires can be prevented from being caught by the groove portions of the 1 st groove portions and the 2 nd groove portions, which should not be caught by the wires. Further, by moving the 1 st holding portion to the 1 st arrangement completion position in a state in which the 1 st holding portion holds the yarn and the yarn is not hooked to the 1 st limit yarn guide, the yarn can be hooked to the 1 st groove portion of the plurality of 1 st groove portions more reliably. Similarly, by moving the 2 nd holding portion to the 2 nd arrangement completion position in a state in which the 2 nd holding portion holds the yarn and the yarn is not hooked to the 2 nd limit yarn guide, the yarn can be hooked to the 2 nd groove portion of the plurality of 2 nd groove portions more reliably.

In the yarn processing device according to the present invention, the 1 st limit yarn guide is preferably disposed at the following position: and a position which is not overlapped with the yarn paths of the plurality of yarns hooked to the 1 st holding portion at the 1 st yarn hooking position when viewed from the arrangement direction.

According to the present invention, when the 1 st holding portion at the 1 st thread hanging position is hooked with the thread, the thread can be further prevented from being accidentally hooked to the 1 st groove portion of the plurality of 1 st groove portions, which should not be hooked with the thread. Further, by moving the 1 st holding portion to the 1 st arrangement completion position in a state in which the 1 st holding portion holds the yarn and the yarn is not hooked to the 1 st limit yarn guide, the yarn can be hooked to the 1 st groove portion to which the yarn should be hooked among the plurality of 1 st groove portions more reliably.

In the yarn processing device according to the present invention, it is preferable that the 1 st holding portion is located upstream of the yarn running space in the yarn running direction and is capable of placing the plurality of yarns held in the 1 st holding grooves in the plurality of yarn running spaces when it is located at the 1 st arrangement completion position, and the 2 nd holding portion is located downstream of the yarn running space in the yarn running direction and is capable of placing the plurality of yarns held in the 2 nd holding portion in the plurality of yarn running spaces when it is located at the 2 nd arrangement completion position.

In the present invention, after a plurality of wires having different pitches on the upstream side and downstream side in the wire traveling direction are collectively caught by a 1 st holding portion at a 1 st yarn catching position and a 2 nd holding portion at a 2 nd yarn catching position, the 1 st holding portion is moved to a 1 st arrangement completion position and the 2 nd holding portion is moved to a 2 nd arrangement completion position. Thus, even if the 1 st limit yarn guide and the 2 nd limit yarn guide described above are not arranged, a plurality of yarns having different pitches on the upstream side and the downstream side in the yarn traveling direction can be arranged in a plurality of yarn traveling spaces arranged at a predetermined pitch in the arrangement direction. Therefore, the number of components for disposing the plurality of wires in the plurality of wire travel spaces can be reduced.

In the yarn processing device according to the present invention, it is preferable that the yarn placement unit further includes a restriction member capable of switching between a restriction state in which the plurality of yarns suspended in the 1 st holding unit and the 2 nd holding unit are restricted from being placed in the yarn running space and a release state in which the restriction is released, the restriction member is configured to obtain the restriction state during a period in which the 1 st holding unit is moved from the 1 st yarn suspending position to the 1 st placement completion position and during a period in which the 2 nd holding unit is moved from the 2 nd yarn suspending position to the 2 nd placement completion position, and the restriction member is configured to obtain the release state when the 1 st holding unit is moved to the 1 st placement completion position and the 2 nd holding unit is moved to the 2 nd placement completion position.

The plurality of wires hooked to the 1 st holding portion and the 2 nd holding portion may be disposed in the plurality of wire travel spaces before each holding portion moves to the disposing completion position. However, in this case, since each holding portion is not moved to the arrangement completion position, there is a possibility that the plurality of wires cannot be appropriately arranged in the corresponding wire travel space. According to the present invention, the plurality of wires can be prevented from being arranged in the plurality of wire travel spaces before the 1 st holding portion and the 2 nd holding portion are moved to the arrangement completion position. Therefore, the plurality of wires can be appropriately arranged in the corresponding plurality of wire travel spaces.

In the yarn processing device according to the present invention, the 2 nd holding portion preferably has a plurality of 2 nd holding grooves having the same pitch in the arrangement direction as the plurality of 1 st holding grooves.

According to the present invention, the 1 st holding portion can be moved to the 1 st arrangement completion position and the 2 nd holding portion can be moved to the 2 nd arrangement completion position while maintaining the pitch of the plurality of wires hooked to the 2 nd holding groove of the 2 nd holding portion to be the same as the pitch in the arrangement direction of the plurality of 1 st holding grooves. Therefore, the plurality of wires having different pitches on the upstream side and the downstream side in the wire traveling direction can be more reliably arranged in the plurality of wire traveling spaces arranged at a predetermined pitch in the arrangement direction.

In the yarn processing device according to the present invention, the 2 nd holding portion is preferably a rotating roller rotatable about a rotation axis along the arrangement direction.

According to the present invention, the plurality of wires hooked to the 2 nd holding portion of the rotating roller are brought into contact with the circumferential surface of the rotating roller in an orthogonal manner by friction force between the circumferential surface of the rotating roller and each wire. Therefore, the pitch of the plurality of wires hooked to the 2 nd holding portion matches the pitch of the plurality of wires hooked to the 1 st groove portion of the 1 st holding portion disposed upstream of the 2 nd holding portion in the wire traveling direction. Further, even if the pitch of the plurality of wires traveling downstream of the 2 nd holding portion in the wire traveling direction is different from the pitch of the wires on the 2 nd holding portion, the pitch of the plurality of wires caught by the 2 nd holding portion can be maintained without being shifted by the frictional force between the circumferential surface of the rotating roller and each wire. In this state, by moving the 1 st holding portion to the 1 st arrangement completion position and moving the 2 nd holding portion to the 2 nd arrangement completion position, a plurality of wires having different pitches on the upstream side and the downstream side in the wire traveling direction can be more reliably arranged in a plurality of wire traveling spaces arranged at a predetermined pitch in the arrangement direction.

Hereinafter, the vertical direction of the paper surface in fig. 1 is referred to as the vertical direction, and the horizontal direction of the paper surface is referred to as the horizontal direction. The direction perpendicular to the paper surface of fig. 1 is referred to as the front-back direction, and the front side of the paper surface is referred to as the front side. Hereinafter, the above directional terms will be appropriately used for explanation.

The spinning production device 1 is configured to take up a plurality of filaments Y spun from the spinning device 2 by a take-up device 4. The spinning device 2 is a device for spinning the molten polymer downward as a yarn Y. As shown in fig. 1, the spinning production apparatus 1 includes a plurality of finish yarn guides 5 each having a finish nozzle, a plurality of guide yarn guides 6, a yarn processing device 7, two yarn guide rollers 11 and 12, a spinning drawing device 3, and a winding device 4. The spinning device 2 and the plurality of oiling agent yarn guides 5 and 6 disposed below the spinning device are disposed at the upper layer (2 layers). The yarn processing device 7, the two godet rolls 11 and 12, the spin-drawing device 3, and the winding device 4 are disposed in the lower layer (layer 1).

The plurality of oiling agent yarn guides 5 are disposed below the spinning device 2, and each of the plurality of yarns Y spun downward from the spinning device 2 is oiled. The plurality of guide yarn guides 6 are disposed at equal intervals in the left-right direction below each of the plurality of oiling agent yarn guides 5, and independently guide the plurality of yarns Y to which the oiling agent is applied.

The yarn processing device 7 is disposed below the plurality of guide yarn guides 6, and applies bundling to the plurality of yarns Y independently guided by the plurality of guide yarn guides 6 by the jet action of compressed air. The yarn processing device 7 includes a 1 st restriction yarn guide 22 and a 2 nd restriction yarn guide 23 (see fig. 2). The plurality of wires Y hooked to the 1 st limit wire guide 22 and the 2 nd limit wire guide 23 run substantially parallel to each other and substantially at equal intervals in the left-right direction. The details of the yarn processing device 7 will be described later.

As shown in fig. 1, the godet rollers 11 and 12 are disposed downstream of the yarn processing device 7 in the yarn traveling direction and are driven to rotate by a motor, not shown. The plurality of filaments Y spun from the spinning device 2 are wound around a godet 11 via a finish yarn guide 5, a guide yarn guide 6, and a filament processing device 7, and are transported to the spin draw device 3 by the godet 11. The plurality of filaments Y heated and stretched by the spin-stretching device 3 are wound around a godet 12, and are transported to the winding device 4 by the godet 12. In addition, in practice, a winding device and other godet are disposed downstream of the godet 12 and upstream of the winding device 4 in the yarn traveling direction, but the description thereof is omitted in fig. 1.

The spin-drawing device 3 is a device for heating and drawing the plurality of filaments Y, and is disposed below the spinning device 2. The spinning and drawing device 3 includes an incubator 60 and 5 godet rolls 91 to 95 housed in the incubator 60. A yarn inlet 60a for introducing the plurality of yarns Y into the incubator 60 is formed at the lower portion of the right side surface portion of the incubator 60, and a yarn outlet 60b for introducing the plurality of yarns Y out of the incubator 60 is formed at the upper portion of the right side surface portion of the incubator 60.

The lower 3 godet rolls 91 to 93 are preheating rolls for preheating the plurality of filaments Y before they are drawn, and the upper two godet rolls 94 and 95 are tempering rolls for heat-setting the plurality of drawn filaments Y. The roller surface temperatures of the upper two godet rollers 94 and 95 are set to be higher than the roller surface temperatures of the lower 3 godet rollers 91 to 93. The wire feeding speed of the upper two godet rollers 94 and 95 is faster than the wire feeding speed of the lower 3 godet rollers 91 to 93.

The plurality of filaments Y introduced into the incubator 60 through the filament introduction port 60a are first preheated to a stretchable temperature while being conveyed by the godet rollers 91 to 93. The preheated plurality of filaments Y are stretched due to the difference in filament conveying speed between the godet 93 and the godet 94. Further, the plurality of filaments Y are heated to a higher temperature during the conveyance by the godet rolls 94 and 95, and then are heat-set in a stretched state. The plurality of filaments Y thus drawn are led out of the incubator 60 through the filament outlet 60b.

The winding device 4 is a device for winding a plurality of yarns Y, and is disposed below the spin-drawing device 3. The winding device 4 has a bobbin holder 13, a contact roller 14, and the like. The bobbin holder 13 has a cylindrical shape extending in the front-rear direction, and is rotationally driven by a motor not shown. The plurality of bobbins B are mounted to the bobbin holder 13 in a state of being aligned in the axial direction of the bobbin holder 13. The winding device 4 simultaneously winds a plurality of wires Y on a plurality of bobbins B by rotating the bobbin holder 13, thereby producing a plurality of packages P. The contact roller 14 contacts the surfaces of the plurality of packages P to apply a predetermined contact pressure, thereby adjusting the shape of the packages P.

(yarn processing device 7)

Next, the yarn processing device 7 will be described in detail with reference to fig. 2 to 8. In fig. 2 and 3, some of the plurality of threads Y are omitted for the sake of explanation. In fig. 7 and 8, the description of the yarn Y is omitted for the sake of explanation. The yarn processing device 7 includes a base 20, a yarn processing section 21, a 1 st limit yarn guide 22, a 2 nd limit yarn guide 23, and a yarn arrangement section 50.

The base material 20 is a member having a substantially rectangular parallelepiped shape. The yarn processing section 21 is a device for applying bundling to the plurality of yarns Y by the jet action of compressed air. As shown in fig. 3 and 4, the thread processing section 21 is formed by arranging a plurality of intersecting pieces 26 in the left-right direction on the front surface of the base material 20 in the front-rear direction. As shown in fig. 1, the yarn processing section 21 is disposed below the plurality of guide yarn guides 6 and above the yarn guide roller 11.

As shown in fig. 4, the yarn processing section 21 has a plurality of yarn travel spaces 31, a plurality of yarn introduction paths 32, and a plurality of jet channels 33. The plurality of yarn running spaces 31 extend along the yarn running direction and are arranged at substantially equal intervals in the arrangement direction (left-right direction in fig. 4) intersecting the yarn running direction. The pitch of the yarn running spaces 31 refers to the distance between centers of the adjacent yarn running spaces 31. In addition, 1 yarn running space 31 is formed in each of the intersecting pieces 26. The yarn running space 31 is formed in a substantially elliptical shape with the left-right direction as the major axis direction as viewed from the yarn running direction. In the yarn advancing direction, the yarn advancing space 31 extends over the entire length of the intersecting piece 26 and is open at both ends.

The plurality of yarn introducing paths 32 are paths for introducing the yarn Y into the yarn advancing space 31, which are provided independently of the plurality of yarn advancing spaces 31, respectively. The thread introduction path 32 extends over the entire length of the intersection 26 in the thread traveling direction and is open at both ends. The yarn introduction path 32 has a 1 st yarn path 36, a 2 nd yarn path 37, and a 3 rd yarn path 38.

The 1 st thread path 36 is a gap formed between two adjacent intersecting pieces 26, and extends in the front-rear direction at substantially the front half of the intersecting piece 26, and the front end in the front-rear direction is an insertion port 36a for the thread Y.

The 2 nd wire path 37 is connected to the end portion of the 1 st wire path 36 on the rear side in the front-rear direction, and extends rightward from the portion connected to the 1 st wire path 36. The 3 rd wire path 38 is connected to the right end of the 2 nd wire path 37, and extends from a portion connected to the 2 nd wire path 37 toward the front side in the front-rear direction. The front end of the 3 rd yarn path 38 in the front-rear direction is connected to the yarn running space 31.

As shown in fig. 4, a substantially half of the front surface of the intersection 26 on the left side of the substantially central portion in the front-rear direction is an inclined surface 26a, and the inclined surface 26a is inclined with respect to the left-right direction so that the left end is on the rear side of the substantially central portion. In the present embodiment, the substantially central portion of the front surface of the cross piece 26 is a portion on the right side of the actual central portion. Further, a substantially half of the front surface of the vein passing sheet 26 on the right side of the substantially central portion in the front-rear direction is an inclined surface 26b, and the inclined surface 26b is inclined with respect to the left-right direction so that the right end is on the rear side of the substantially central portion. Accordingly, the inclined surfaces 26a, 26b are located on both sides of the 1 st wire path 36 in the left-right direction. Thus, the 1 st thread path 36 is guided by the inclined surfaces 26a and 26b to be inserted by the threads Y which are caught by the 1 st limit thread guide 22 and the 2 nd limit thread guide 23, which will be described later, and travel substantially parallel to each other.

A plurality of jet channels 33 are provided independently of the plurality of yarn running spaces 31. The ejection channels 33 are formed in 1 in each of the intersecting pieces 26, extend in the front-rear direction, and have front ends (front end portions) that are ejection openings 33a that open on the front-rear side wall surfaces of the connection portions of the 2 nd wire path 37 and the 3 rd wire path 38. Thus, the ejection port 33a faces the wire running space 31 in the front-rear direction via the 3 rd wire path 38. The rear end portion of the injection flow path 33 is connected to the fluid supply source 40 via the fluid supply flow path 43. The fluid supply passage 43 is provided with a valve 39. When the valve 39 is opened, a fluid such as air supplied from the fluid supply source 40 is supplied to the ejection flow path 33 through the fluid supply flow path 43, and ejected from the ejection port 33a of the ejection flow path 33 into the yarn running space 31. Thereby, a twisting back flow is generated in the yarn running space 31, and bundling property is applied to the filaments forming the yarn Y running in the yarn running space 31.

As shown in fig. 2, 5, and the like, the 1 st limit wire guide 22 is disposed at a portion of the front surface of the base material 20 on the upstream side of the wire processing unit 21 in the wire traveling direction. As shown in fig. 2, the 1 st limit yarn guide 22 includes a plurality of 1 st groove portions 22a arranged at equal intervals in the left-right direction, which is the arrangement direction of the plurality of yarns Y. The pitch of the 1 st groove 22a refers to the distance between centers of the adjacent 1 st grooves 22a. The pitch of the 1 st groove portions 22a is the same as the pitch of the thread running spaces 31. The 1 st groove 22a opens toward the front side in the front-rear direction. The front direction in the front-rear direction corresponds to the opening direction in which the 1 st groove 22a of the present invention opens. As shown in fig. 5, the 1 st limit yarn guide 22 is arranged at a position not overlapping with yarn paths of the plurality of yarns Y caught by the 1 st holding yarn guide 24 (described later) at the 1 st yarn hanging position when viewed from the left-right direction. In other words, the 1 st limit yarn guide 22 is disposed at a position on the rear side of the yarn path of the plurality of yarns Y hooked on the 1 st holding yarn guide 24 in the 1 st yarn hanging position in the front-rear direction.

As shown in fig. 2, 5, and the like, the 2 nd limit wire guide 23 is disposed at a portion of the front surface of the base material 20 on the downstream side of the wire processing unit 21 in the wire traveling direction. As shown in fig. 2, the 2 nd limit wire guide 23 has a plurality of 2 nd groove portions 23a arranged in the left-right direction at the same pitch as the plurality of 1 st groove portions 22 a. The pitch of the 2 nd groove portions 23a refers to the distance between the centers of the adjacent 2 nd groove portions 23a. The 2 nd groove portion 23a is opened toward the front side in the front-rear direction. The direction toward the front side in the front-rear direction corresponds to the opening direction in which the 2 nd groove portion 23a of the present invention is opened.

The 1 st groove 22a and the 2 nd groove 23a are located at substantially the same positions in the lateral direction. Then, the yarn Y traveling in the yarn traveling direction passes between the adjacent 1 st groove portions 22a and between the adjacent 2 nd groove portions 23a, and thereby the movement of the yarn Y in the right-left direction is restricted, and the yarn path is defined. The 1 st limit yarn guide 22 and the 2 nd limit yarn guide 23 have a function of supporting the yarn Y when bundling is applied to the yarn Y in the yarn processing section 21.

The yarn arrangement section 50 is configured to arrange the plurality of yarns Y in the plurality of yarn running spaces 31. The thread arrangement portion 50 includes the 1 st holding wire guide 24 (the 1 st holding portion of the present invention), the 2 nd holding wire guide 25 (the 2 nd holding portion of the present invention), and the interlocking mechanism 30.

The 1 st holding wire guide 24 is a wire guide capable of holding the plurality of wires Y hooked to the 1 st limiting wire guide 22. The 1 st holding wire guide 24 is a cylindrical member extending in the left-right direction, and has a plurality of 1 st holding grooves 24a having the same pitch in the left-right direction as the 1 st groove portions 22a. The pitch of the 1 st holding groove 24a refers to the distance between centers of the adjacent 1 st holding grooves 24a. The movement of the plurality of wires Y hooked in the 1 st holding groove 24a in the lateral direction is restricted. The 1 st groove portions 22a are positioned substantially at the same positions as the 1 st holding grooves 24a in the lateral direction. The 1 st holding guide 24 is movable between a 1 st thread hanging position (see fig. 2 and 5) at which the plurality of threads Y are caught by the 1 st holding guide 24, and a 1 st arrangement completion position (see fig. 3 and 6) at which the plurality of threads Y are retracted from the thread path when the 1 st limit guide 22 and the 2 nd limit guide 23 are caught by the threads. The yarn path in the case where the 1 st limit yarn guide 22 and the 2 nd limit yarn guide 23 hook the plurality of yarns Y is the yarn path of the yarn Y shown in fig. 6.

As shown in fig. 2 and 5, the 1 st holding yarn guide 24 is located downstream of the 1 st limiting yarn guide 22 in the yarn traveling direction and is a position on the front side of the yarn processing section 21 in the front-rear direction when in the 1 st yarn hanging position. Further, as shown in fig. 5, when the 1 st holding yarn guide 24 is at the 1 st yarn hanging position, the yarn path is shifted to the front side in the front-rear direction from the yarn path when the 1 st limiting yarn guide 22 and the 2 nd limiting yarn guide 23 are hooked with the plurality of yarns Y when viewed from the left-right direction. Further, as shown in fig. 3 and 6, the 1 st holding wire guide 24 is located upstream of the 1 st limit wire guide 22 in the wire traveling direction and is a position on the rear side of the 1 st limit wire guide 22 in the front-rear direction when in the 1 st arrangement completion position. The 1 st holding yarn guide 24 is configured to cross the plurality of yarns Y to the corresponding 1 st groove portions 22a while moving from the 1 st yarn hanging position to the 1 st arrangement completion position.

The 2 nd holding wire guide 25 is a wire guide capable of holding the plurality of wires Y hooked to the 1 st limiting wire guide 22. The 2 nd holding wire guide 25 is disposed on the downstream side of the 1 st holding wire guide 24 in the wire traveling direction. The 2 nd holding wire guide 25 is a cylindrical member extending in the left-right direction, and has a plurality of 2 nd holding grooves 25a having the same pitch in the left-right direction as the plurality of 2 nd groove portions 23a. The pitch of the 2 nd groove portions 25a refers to the distance between the centers of the adjacent 2 nd groove portions 25a. The movement of the plurality of wires Y hooked in the 2 nd holding groove 25a in the lateral direction is restricted. The positions of the 2 nd groove portions 23a in the left-right direction are substantially the same as the positions of the 2 nd holding grooves 25a. The 2 nd holding guide 25 is movable between a 2 nd thread hanging position (see fig. 2 and 5) at which the plurality of threads Y are caught by the 2 nd holding guide 25, and a 2 nd arrangement completion position (see fig. 3 and 6) at which the plurality of threads Y are retracted from the thread path when the 1 st limit guide 22 and the 2 nd limit guide 23 are caught by the threads Y.

As shown in fig. 2 and 5, the 2 nd holding wire guide 25 is located at a position upstream of the 2 nd limiting wire guide 23 in the wire traveling direction, downstream of the 1 st holding wire guide 24, and forward of the wire processing unit 21 in the front-rear direction when in the 2 nd wire hanging position. Further, as shown in fig. 5, when the 2 nd holding yarn guide 25 is at the 2 nd yarn hanging position, it is offset from the front side in the front-rear direction when the 1 st limit yarn guide 22 and the 2 nd limit yarn guide 23 are hooked with the plurality of yarns Y, when viewed from the left-right direction. Further, as shown in fig. 3 and 6, when the 2 nd holding wire guide 25 is in the 2 nd arrangement completion position, the position is located downstream of the 2 nd limiting wire guide 23 in the wire traveling direction and is the rear side of the 2 nd limiting wire guide 23 in the front-rear direction. The 2 nd holding yarn guide 25 is configured to cross the plurality of yarns Y to the corresponding plurality of 2 nd groove portions 23a while moving from the 2 nd yarn hanging position to the 2 nd placement completion position.

As shown in fig. 2 and 5, the 1 st holding wire guide 24 in the 1 st wire-hanging position and the 2 nd holding wire guide 25 in the 2 nd wire-hanging position are adjacent to each other in the wire traveling direction. Here, the mutually adjacent means that the distance between the 1 st holding wire guide 24 and the 2 nd holding wire guide 25 is 0 to 10mm.

The interlocking mechanism 30 interlocks the movement of the 1 st holding wire guide 24 between the 1 st wire-hanging position and the 1 st arrangement completion position with the movement of the 2 nd holding wire guide 25 between the 2 nd wire-hanging position and the 2 nd arrangement completion position. As shown in fig. 7, the interlocking mechanism 30 includes a 1 st swing arm 41 rotatable about a 1 st swing axis 51 in the left-right direction and a 2 nd swing arm 42 rotatable about a 2 nd swing axis 52 in the left-right direction.

As shown in fig. 2, the 1 st swing arm 41 supports the left end of the 1 st holding wire guide 24 by its front end portion cantilever. The 1 st swinging arm 41 is rotated about the 1 st swinging shaft 51, whereby the 1 st holding wire guide 24 can swing between the 1 st wire hanging position and the 1 st arrangement completion position. When the 1 st holding wire guide 24 is at the 1 st threading position, the 1 st swing arm 41 is extended in the front-rear direction (see fig. 7). When the 1 st holding wire guide 24 is at the 1 st arrangement completion position, the 1 st swing arm 41 extends obliquely upward and forward (see fig. 8).

Further, as shown in fig. 2, the 2 nd swing arm 42 cantilever-supports the left end of the 2 nd holding wire guide 25 by its front end portion. The 2 nd swinging arm 42 is pivoted about the 2 nd swinging shaft 52, whereby the 2 nd holding wire guide 25 can swing between the 2 nd wire hanging position and the 2 nd arrangement completion position. When the 2 nd holding wire guide 25 is at the 2 nd wire hanging position, the 2 nd swinging arm 42 is extended in the front-rear direction (see fig. 7). When the 2 nd holding wire guide 25 is at the 2 nd arrangement completion position, the 2 nd swinging arm 42 is extended obliquely downward and forward (see fig. 8).

Further, as shown in fig. 7, the 1 st swing arm 41 includes a 1 st gear 53 having 4 tooth shapes, and the 2 nd swing arm 42 includes a 2 nd gear 54 having 5 tooth shapes. The 1 st gear 53 is intermeshed with the 2 nd gear 54. The number of tooth forms constituting the 1 st gear 53 may be other than 4. The number of tooth forms constituting the 2 nd gear 54 may be other than 5.

The interlocking mechanism 30 rotates the 1 st swing arm 41 and the 2 nd swing arm 42 in interlocking with each other by meshing the 1 st gear 53 and the 2 nd gear 54. The interlocking mechanism 30 includes, for example, a motor, not shown, that rotationally drives either one of the 1 st swing shaft 51 and the 2 nd swing shaft 52. However, the interlocking mechanism 30 is not limited to having a motor, and may have a lever (not shown) attached to any one of the 1 st swing arm 41 and the 2 nd swing arm 42, for example. In this case, the operator starts rotation of either one of the 1 st swing arm 41 and the 2 nd swing arm 42 by pulling the lever. Then, the 1 st gear 53 meshes with the 2 nd gear 54, and thus the other of the 1 st swing arm 41 and the 2 nd swing arm 42 rotates in conjunction with each other.

(hanging yarn to yarn processing device 7)

Next, a specific procedure for hooking the 1 st limit yarn guide 22 and the 2 nd limit yarn guide 23 of the plurality of yarns Y to the yarn processing device 7 will be described. In the spinning production equipment 1, after yarn is hung on the guide yarn guide 6, yarn is hung on both limit yarn guides of the yarn processing device 7. The 1 st limit wire guide 22 and the 2 nd limit wire guide 23 of the wire processing apparatus 7 are threaded by using, for example, a suction gun 80 (a winding section of the present invention). The suction gun 80 sucks the plurality of threads Y and gathers the plurality of threads Y.

Before threading the yarn to the yarn processing device 7, the interlocking mechanism 30 moves the 1 st holding yarn guide 24 to the 1 st threading position and moves the 2 nd holding yarn guide 25 to the 2 nd threading position (see fig. 2). Then, as shown in fig. 5, the operator hooks the plurality of wires Y collectively sucked by the suction gun 80 to the 1 st holding groove 24a of the 1 st holding wire guide 24 and the 2 nd holding groove 25a of the 2 nd holding wire guide 25. At this time, the worker performs yarn hanging while adjusting the position of the suction gun 80 so that the interval between the plurality of yarns Y sucked by the suction port 81 of the suction gun 80 coincides with the interval between the 1 st holding grooves 24a of the 1 st holding yarn guide 24 at the 1 st yarn hanging position and the interval between the 2 nd holding grooves 25a of the 2 nd holding yarn guide 25 at the 2 nd yarn hanging position.

Next, the 1 st holding wire guide 24 at the 1 st wire-hanging position is moved toward the 1 st arrangement completion position by the interlocking mechanism 30, and the 2 nd holding wire guide 25 at the 2 nd wire-hanging position is moved toward the 2 nd arrangement completion position in conjunction with this. Specifically, when viewed from the right side in the left-right direction, the 1 st swinging arm 41 is rotated counterclockwise (solid arrow in fig. 7) about the 1 st swinging shaft 51, whereby the 1 st holding wire guide 24 swings from the 1 st wire-hanging position toward the 1 st arrangement completion position. Further, when viewed from the right side in the left-right direction, the 2 nd holding wire guide 25 swings from the 2 nd wire hanging position toward the 2 nd arrangement completion position by the 2 nd swinging arm 42 rotating clockwise (solid arrow in fig. 7) about the 2 nd swinging shaft 52.

The plurality of wires Y held by the 1 st holding wire guide 24 are delivered to the 1 st groove portions 22a of the 1 st limiting wire guide 22 while the 1 st holding wire guide 24 is moving from the 1 st wire-hanging position to the 1 st arrangement completion position. Specifically, after the yarn Y hooked to the 1 st holding groove 24a contacts the bottom of the 1 st groove 22a of the 1 st limit yarn guide 22, the 1 st holding yarn guide 24 is further moved toward the 1 st arrangement completion position, whereby the yarn Y hooked to the 1 st holding groove 24a is delivered to the 1 st groove 22a. Thus, the yarn hanging operation on the 1 st limit yarn guide 22 is completed.

The plurality of wires Y held by the 2 nd holding guide 25 are delivered to the 2 nd groove portions 23a of the 2 nd restricting guide 23 while the 2 nd holding guide 25 is moving from the 2 nd threading position to the 2 nd arrangement completion position. Specifically, after the yarn Y hooked in the 2 nd holding groove 25a contacts the bottom of the 2 nd groove portion 23a of the 2 nd restriction yarn guide 23, the 2 nd holding yarn guide 25 is further moved toward the 2 nd arrangement completion position, whereby the yarn Y hooked in the 2 nd holding groove 25a is delivered to the 2 nd groove portion 23a. Thereby, the yarn hanging operation on the 2 nd limit yarn guide 23 is completed.

The plurality of wires Y hooked on the 1 st limit wire guide 22 and the 2 nd limit wire guide 23 are guided by the inclined surfaces 26a and 26b of the wire processing unit 21 and inserted into the 1 st wire path 36.

(Effect)

The yarn processing device 7 of the present embodiment includes a 1 st holding yarn guide 24 capable of acquiring the 1 st yarn hanging position and the 1 st arrangement completion position, and a 2 nd holding yarn guide 25 capable of acquiring the 2 nd yarn hanging position and the 2 nd arrangement completion position. The 1 st holding wire guide 24 in the 1 st wire-hanging position and the 2 nd holding wire guide 25 in the 2 nd wire-hanging position are adjacent to each other in the wire traveling direction. It is difficult to arrange the plurality of wires Y converging toward the suction gun 80 and having different pitches in the left-right direction (arrangement direction) in the upstream side and the downstream side of the wire advancing direction in the plurality of wire advancing spaces 31 extending along the wire advancing direction and arranged at a predetermined pitch in the left-right direction. In the present embodiment, since the 1 st holding wire guide 24 at the 1 st wire-hanging position and the 2 nd holding wire guide 25 at the 2 nd wire-hanging position are adjacent to each other in the wire traveling direction, the plurality of wires Y can be caught in the 1 st holding wire guide 24 and the 2 nd holding wire guide 25 at the same interval in the left-right direction. Then, the 1 st holding yarn guide 24 having the plurality of yarns Y caught therein obtains the 1 st arrangement completion position, and the 2 nd holding yarn guide 25 having the plurality of yarns Y caught therein obtains the 2 nd arrangement completion position, whereby the plurality of yarns Y can be arranged in the plurality of yarn travelling spaces 31 in a state where the plurality of yarns Y are aligned with the pitches in the left-right direction of the plurality of yarn travelling spaces 31. Therefore, the plurality of wires Y having different upstream-side and downstream-side pitches in the wire traveling direction can be easily arranged in the plurality of wire traveling spaces 31 arranged at a predetermined pitch in the left-right direction.

The yarn processing device 7 of the present embodiment includes the 1 st limit yarn guide 22 disposed upstream of the yarn travel space 31 in the yarn travel direction and the 2 nd limit yarn guide 23 disposed downstream. The 1 st arrangement completion position is a position where the 1 st holding wire guide 24 retreats from the wire passage when the 1 st limit wire guide 22 and the 2 nd limit wire guide 23 hook the plurality of wires Y, and the 2 nd arrangement completion position is a position where the 2 nd holding wire guide 25 retreats from the wire passage when the 1 st limit wire guide 22 and the 2 nd limit wire guide 23 hook the plurality of wires Y. The 1 st holding yarn guide 24 connects the plurality of yarns Y to the 1 st limiting yarn guide 22 while moving from the 1 st yarn hanging position to the 1 st arrangement completion position. The 2 nd holding yarn guide 25 delivers the plurality of yarns Y to the 2 nd limiting yarn guide 23 while moving from the 2 nd yarn hanging position to the 2 nd arrangement completion position. When a plurality of wires Y having different pitches on the upstream side and the downstream side in the wire traveling direction are to be hooked on the 1 st limit wire guide 22 and the 2 nd limit wire guide 23, the following problems occur. That is, even if the pitch of the plurality of wires Y is made to coincide with the pitch of one of the 1 st limit wire guide 22 and the 2 nd limit wire guide 23, the pitch of the plurality of wires Y is different between the upstream side and the downstream side in the wire traveling direction, and thus the pitch of the other limit wire guide is also made to coincide with the pitch of the other limit wire guide. In the present embodiment, after the plurality of wires Y are collectively hooked to the 1 st holding wire guide 24 at the 1 st wire-hanging position and the 2 nd holding wire guide 25 at the 2 nd wire-hanging position, the 1 st holding wire guide 24 is moved to the 1 st arrangement completion position, and the 2 nd holding wire guide 25 is moved to the 2 nd arrangement completion position, whereby the plurality of wires Y are easily collectively hooked to the 1 st limit wire guide 22 and the 2 nd limit wire guide 23. As a result, the plurality of wires Y having different upstream-side and downstream-side pitches in the wire traveling direction can be easily arranged in the plurality of wire traveling spaces 31 arranged at a predetermined pitch in the left-right direction.

In the present embodiment, the 2 nd holding wire guide 25 has a plurality of 2 nd holding grooves 25a having the same pitch in the lateral direction as the intervals in the lateral direction of the plurality of 2 nd groove portions 23a. Accordingly, since the intervals of the plurality of wires Y caught in the 2 nd holding groove 25a of the 2 nd holding wire guide 25 are the same as the intervals in the lateral direction of the plurality of 2 nd groove portions 23a, the plurality of wires Y can be more reliably delivered to the corresponding 2 nd groove portions 23a, respectively. This makes it possible to accurately hang the 2 nd limit yarn guide 23, and to accurately dispose the plurality of yarns Y in the plurality of yarn travel spaces 31 aligned in the left-right direction.

Further, in the present embodiment, the thread placement unit 50 includes a linking mechanism 30, and the linking mechanism 30 links the movement of the 1 st holding thread guide 24 between the 1 st thread-hanging position and the 1 st placement completion position and the movement of the 2 nd holding thread guide 25 between the 2 nd thread-hanging position and the 2 nd placement completion position. When only the wire Y is transferred from one holding guide to the limiting guide, the wire Y may float from the limiting guide after the transfer of the wire Y from the other holding guide to the limiting guide, and may be separated. According to the present embodiment, the wire Y can be delivered from the 1 st holding guide 24 to the 1 st limiting guide 22 and the wire Y can be delivered from the 2 nd holding guide 25 to the 2 nd limiting guide 23 at the same timing. Therefore, the threading operation to the 1 st limit wire guide 22 and the 2 nd limit wire guide 23 can be performed more reliably.

In the present embodiment, the interlocking mechanism 30 includes: the 1 st swinging arm 41 is rotatable about a 1 st swinging shaft 51 extending in the left-right direction, and supports the 1 st holding wire guide 24 so as to be swingable; and a 2 nd swinging arm 42 which can rotate around a 2 nd swinging shaft 52 along the left-right direction and supports the 2 nd holding wire guide 25 so as to be swingable. The 1 st swing arm 41 includes a 1 st gear 53, and the 2 nd swing arm 42 includes a 2 nd gear 54. The interlocking mechanism 30 rotates the 1 st swing arm 41 and the 2 nd swing arm 42 in interlocking with each other by meshing the 1 st gear 53 and the 2 nd gear 54, and thereby can interlock the movement of the 1 st holding wire guide 24 with the movement of the 2 nd holding wire guide 25. Accordingly, the 1 st swing arm 41 and the 2 nd swing arm 42 are rotated in conjunction with each other by the meshing of the 1 st gear 53 and the 2 nd gear 54, and thereby the 1 st holding wire guide 24 and the 2 nd holding wire guide 25 can be swung in conjunction with each other. Therefore, complicated structure and control are not required to move the 1 st holding wire guide 24 and the 2 nd holding wire guide 25 in conjunction with each other.

In the present embodiment, the 1 st yarn hanging position is the following position: when viewed from the left-right direction, the 1 st holding guide 24 is positioned at a position offset from the front side in the front-rear direction of the yarn path, i.e., the opening direction in which the 1 st groove 22a opens, when the 1 st limiting guide 22 and the 2 nd limiting guide 23 hold the plurality of yarns Y. The 2 nd wire hanging position is as follows: when viewed from the left-right direction, the 2 nd holding guide 25 is positioned at a position offset from the front side in the front-rear direction of the yarn path, i.e., the opening direction in which the 2 nd groove portion 23a opens, when the 1 st limit guide 22 and the 2 nd limit guide 23 hold the plurality of yarns Y. Accordingly, when the plurality of wires Y are caught by the 1 st holding wire guide 24 at the 1 st wire-hanging position and the 2 nd holding wire guide 25 at the 2 nd wire-hanging position, the wires Y can be prevented from being accidentally caught by the groove portions of the 1 st groove portions 22a and the 2 nd groove portions 23a, which should not be caught by the wires Y. Further, by moving the 1 st holding wire guide 24 to the 1 st arrangement completion position in a state in which the 1 st holding wire guide 24 holds the wire Y and the wire Y is not hooked to the 1 st limiting wire guide 22, the wire Y can be hooked to the 1 st groove 22a of the 1 st groove 22a to be hooked to the wire Y more reliably. Similarly, by moving the 2 nd holding wire guide 25 to the 2 nd arrangement completion position in a state in which the 2 nd holding wire guide 25 holds the wire Y and the wire Y is not hooked to the 2 nd limiting wire guide 23, the wire Y can be hooked to the 2 nd groove portion 23a to which the wire Y should be hooked among the plurality of 2 nd groove portions 23a more reliably.

Further, in the present embodiment, the 1 st limit wire guide 22 is disposed at the following positions: and is not overlapped with the yarn paths of the plurality of yarns Y hooked to the 1 st holding yarn guide 24 at the 1 st yarn hooking position when viewed from the left-right direction. Accordingly, when the 1 st holding yarn guide 24 at the 1 st yarn hanging position is hooked with the yarn Y, the yarn Y can be further prevented from being accidentally hooked with the 1 st groove 22a of the plurality of 1 st groove 22a, which should not be hooked with the yarn Y. Further, by moving the 1 st holding wire guide 24 to the 1 st arrangement completion position in a state in which the 1 st holding wire guide 24 holds the wire Y and the wire Y is not hooked to the 1 st limiting wire guide 22, the wire Y can be hooked to the 1 st groove 22a of the 1 st groove 22a to be hooked to the wire Y more reliably.

(modification)

A modified example in which the above-described embodiment is modified will be described below. However, the same reference numerals are given to the components having the same configuration as those of the above-described embodiment, and the description thereof will be omitted as appropriate.

(modification 1)

In the above embodiment, the 2 nd holding wire guide 25 has the plurality of 2 nd holding grooves 25a having the same interval in the left-right direction as the interval in the left-right direction of the plurality of 2 nd groove portions 23a. However, the 2 nd holding wire guide may be configured without a groove. For example, as shown in fig. 9, the 2 nd holding wire guide 125 of the 1 st modification is a rotating roller rotatable about a rotation axis extending in the left-right direction. The rotating roller may be a driving roller that is rotated by a motor (not shown), or may be a free roller (driven roller) that does not have a driving force. In this case, the 1 st holding yarn guide 24 included in the yarn processing device 107 has the same structure as in the above embodiment. Fig. 9 shows the 1 st holding wire guide 24 in the 1 st wire-hanging position and the 2 nd holding wire guide 125 in the 2 nd wire-hanging position. According to this configuration, the plurality of wires Y hooked to the 2 nd holding yarn guide 125 as the rotating roller are in contact with the circumferential surface of the rotating roller in an orthogonal manner due to the frictional force between the circumferential surface of the rotating roller and each wire Y. Therefore, the interval between the plurality of wires Y hooked to the 2 nd holding guide 125 matches the interval between the plurality of wires Y hooked to the 1 st holding groove 24a of the 1 st holding guide 24 arranged on the upstream side of the 2 nd holding guide 125 in the wire advancing direction. Further, due to the friction force between the peripheral surface of the rotating roller and each wire Y, even if the interval between the plurality of wires Y traveling downstream of the 2 nd holding wire guide 125 in the wire traveling direction is narrowed by using the suction gun 80, the interval between the plurality of wires Y hooked to the 2 nd holding wire guide 125 can be maintained without being deviated. Therefore, the intervals of the plurality of wires Y hooked on the 2 nd holding wire guide 125 are the same as the intervals of the 1 st holding grooves 24a in the lateral direction, and further the intervals of the 1 st groove 22a and the 2 nd groove 23a in the lateral direction. Therefore, the plurality of wires Y can be more reliably delivered to the corresponding 2 nd groove portions 23a. This makes it possible to more accurately perform the yarn threading operation on the yarn processing device 107.

In the yarn processing device 107 according to the modification 1, the posture of the 2 nd holding yarn guide 125 as the rotating roller is appropriately adjusted in consideration of the frictional force between the peripheral surface of the rotating roller and the plurality of yarns Y. In the modification 1, the timing of hooking the plurality of wires Y to the 1 st holding guide 24 at the 1 st yarn hooking position and the 2 nd holding guide 125 at the 2 nd yarn hooking position is not necessarily the same. Specifically, after the plurality of wires Y are hooked to the 1 st holding wire guide 24 positioned at the 1 st wire-hanging position, the plurality of wires Y may be hooked to the 2 nd holding wire guide 125 positioned at the 2 nd wire-hanging position immediately after the hooking.

(modification 2)

In the above embodiment, the yarn processing device 7 is configured to dispose the plurality of yarns Y in the plurality of yarn travel spaces 31 by transferring the plurality of yarns Y from the 1 st holding yarn guide 24 to the 1 st limiting yarn guide 22 and transferring the plurality of yarns Y from the 2 nd holding yarn guide 25 to the 2 nd limiting yarn guide 23. However, the yarn processing device of the present invention may not have the 1 st limit yarn guide 22 and the 2 nd limit yarn guide 23. For example, as shown in fig. 10, the wire processing device 207 includes a wire arrangement portion 150 having a 1 st holding wire guide 224 and a 2 nd holding wire guide 225.

The 1 st holding guide 224 has a plurality of 1 st holding grooves (not shown) having the same pitch in the left-right direction as the pitch in the left-right direction of the plurality of wire advancing spaces 31. The 1 st holding wire guide 224 can obtain a 1 st wire-hanging position (position of fig. 10) and a 1 st arrangement completion position (position of fig. 11). The 1 st thread-hanging position is a position where the plurality of threads Y are hooked to the 1 st holding thread guide 224. As shown in fig. 10, the 1 st holding yarn guide 224 is located upstream of the yarn advancing space 31 in the yarn advancing direction when it is located at the 1 st yarn hanging position. As shown in fig. 11, when the 1 st holding yarn guide 224 is in the 1 st arrangement completion position, it is located upstream of the yarn running space 31 in the yarn running direction, and the plurality of yarns Y held by the 1 st holding grooves can be arranged in the plurality of yarn running spaces 31. In modification 2, the 1 st thread-hanging position of the 1 st holding thread guide 224 and the 1 st arrangement completion position are the same.

The 2 nd holding guide 225 has a plurality of 2 nd holding grooves (not shown) having the same pitch in the left-right direction as the pitch in the left-right direction of the plurality of wire travel spaces 31. The 2 nd holding wire guide 225 can obtain the 2 nd wire hanging position (position of fig. 10) and the 2 nd arrangement completion position (position of fig. 11). The 2 nd thread hanging position is a position where the plurality of threads Y are hooked to the 2 nd holding thread guide 225. As shown in fig. 10, the 2 nd holding yarn guide 225 is located upstream of the yarn advancing space 31 in the yarn advancing direction when it is located at the 2 nd yarn hanging position. As shown in fig. 11, when the 2 nd holding yarn guide 225 is in the 2 nd arrangement completion position, it is located downstream of the yarn running space 31 in the yarn running direction, and the plurality of yarns Y held in the 2 nd holding grooves can be arranged in the plurality of yarn running spaces 31. Further, the 1 st holding wire guide 224 in the 1 st wire-hanging position and the 2 nd holding wire guide 225 in the 2 nd wire-hanging position are adjacent to each other in the wire traveling direction.

The movement of the 2 nd holding wire guide 225 between the 2 nd wire-hanging position and the 2 nd arrangement completion position may be performed by a motor-driven movement mechanism (not shown), for example, or may be performed manually by an operator.

The yarn arrangement portion 150 according to modification 2 further includes a restricting member 231, a supporting member 232, and a rotation shaft 233. The restricting member 231 is a member that can be switched between a restricting state and a releasing state. In the restricting state, the restricting member 231 restricts the plurality of wires Y hooked to the 1 st holding wire guide 224 and the 2 nd holding wire guide 225 from being placed in the wire advancing space 31 (see fig. 10). When the restricting member 231 is in the released state, the restriction is released (see fig. 11). The regulating member 231 is disposed downstream of the yarn advancing space 31 in the yarn advancing direction. The rotation shaft 233 is a rotation shaft extending in the lateral direction, and is formed in the base material 20. The base end portion of the support member 232 is connected to the rotation shaft 233, and the tip end portion is connected to the regulating member 231. In other words, the restricting member 231 is connected to the rotation shaft 233 via the supporting member 232. The restricting member 231 can be switched between the restricting state and the releasing state by swinging about the rotation shaft 233.

Next, the steps when a plurality of threads Y are arranged in the thread advancing space 31 of the thread processing unit 21 will be described below. The threading to the 1 st holding wire guide 224 and the 2 nd holding wire guide 225 is performed using, for example, the suction gun 80. First, as shown in fig. 10, the 1 st holding wire guide 224 is moved to the 1 st wire hanging position, and the 2 nd holding wire guide 225 is moved to the 2 nd wire hanging position. At this time, the restricting member 231 is in the restricting state. Then, the operator hooks the plurality of wires Y collectively sucked by the suction gun 80 to the 1 st holding groove of the 1 st holding wire guide 224 and the 2 nd holding groove of the 2 nd holding wire guide 225.

Next, as shown in fig. 11, the 2 nd holding wire guide 225 is moved to the 2 nd deployment completion position. The restricting member 231 takes a restricting state while the 2 nd holding wire guide 225 reaches the 2 nd arrangement completion position from the 2 nd wire hanging position. When the 2 nd holding wire guide 225 is moved to the 2 nd arrangement completion position, the restricting member 231 rotates downward in the vertical direction around the rotation shaft 233, and is released as shown in fig. 11. Thus, the plurality of wires Y hooked to the 1 st holding wire guide 224 and the 2 nd holding wire guide 225 are arranged in the plurality of wire advancing spaces 31.

In modification 2, after a plurality of wires Y having different upstream and downstream side pitches in the wire traveling direction are collectively caught by the 1 st holding wire guide 224 at the 1 st yarn-catching position and the 2 nd holding wire guide 225 at the 2 nd yarn-catching position, the 1 st holding wire guide 224 is moved to the 1 st arrangement completion position and the 2 nd holding wire guide 225 is moved to the 2 nd arrangement completion position. Accordingly, even if the 1 st limit yarn guide 22 and the 2 nd limit yarn guide 23 described above are not arranged, the plurality of yarns Y having different pitches on the upstream side and the downstream side in the yarn traveling direction can be arranged in the plurality of yarn traveling spaces 31 arranged at a predetermined pitch in the arrangement direction. Therefore, the number of members for disposing the plurality of wires Y in the plurality of wire travel spaces can be reduced.

On the other hand, the plurality of wires Y hooked to the 1 st holding wire guide 224 and the 2 nd holding wire guide 225 may be placed in the plurality of wire travel spaces 31 before each holding wire guide is moved to the placement completion position. However, in this case, since each holding yarn guide is not moved to the arrangement completion position, the plurality of yarns Y may not be appropriately arranged in the corresponding yarn running space 31. According to modification 2, the plurality of wires Y can be prevented from being placed in the plurality of wire advancing spaces 31 before the 1 st holding wire guide 224 and the 2 nd holding wire guide 225 are moved to the placement completion position. Therefore, the plurality of wires Y can be appropriately arranged in the corresponding plurality of wire travel spaces 31.

In the modification 2, the 1 st thread-hanging position of the 1 st holding thread guide 224 is the same as the 1 st arrangement completion position, but the 1 st holding thread guide 224 may be moved between the 1 st thread-hanging position and the 1 st arrangement completion position. In this case, for example, the 1 st holding wire guide 224 can move between the 1 st wire-hanging position and the 1 st arrangement completion position. The 1 st yarn hanging position is located downstream of the yarn running space 31 in the yarn running direction, and the 1 st yarn arrangement completion position is located upstream of the yarn running space 31 in the yarn running direction. In this case, for example, the 2 nd thread hanging position and the 2 nd arrangement completion position of the 2 nd holding thread guide 225 are both the same positions on the downstream side of the thread advancing space 31 in the thread advancing direction. In the modification 2, the 1 st holding wire guide 224 and the 2 nd holding wire guide 225 may be both moved.

In the modification 2, the 2 nd holding wire guide 225 has a configuration including a plurality of 2 nd holding grooves. However, the 2 nd holding wire guide 225 may be configured without a plurality of 2 nd holding grooves. For example, the 2 nd holding wire guide 225 may be a rotating roller rotatable about a rotation axis extending in the lateral direction, as in the 1 st modification.

(other modifications)

In the above embodiment, the yarn processing device 7 is a device for applying bundling properties to the plurality of yarns Y by the jet action of compressed air. However, the yarn processing device is not limited thereto. The yarn processing device also includes other devices in which a limiting yarn guide (1 st limiting yarn guide and 2 nd limiting yarn guide) is provided on the upstream side and the downstream side of the yarn processing section in order to perform a predetermined process on a plurality of yarns Y traveling substantially parallel to each other and at substantially equal intervals by the yarn processing section. For example, the yarn processing device includes a yarn processing section including an oil nozzle for applying oil to the plurality of yarns Y, a tension sensor for detecting tension of the plurality of yarns Y, and the like.

In the above embodiment, the 1 st holding wire guide 24 swings the 1 st swing arm 41, and the 2 nd holding wire guide 25 swings the 2 nd swing arm 42. However, the 1 st holding wire guide 24 and the 2 nd holding wire guide 25 are not limited to the swing type. For example, the 1 st holding wire guide 24 may be movable between the 1 st wire-hanging position and the 1 st arrangement completion position by a vertical movement and a longitudinal movement. Similarly, the 2 nd holding wire guide 25 can be moved between the 2 nd wire-hanging position and the 2 nd arrangement completion position by moving in the up-down direction and moving in the front-back direction. Specifically, the 1 st holding wire guide 24 in the 1 st wire hanging position moves backward after moving upward, thereby moving to the 1 st arrangement completion position. Further, the 2 nd holding wire guide 25 at the 2 nd wire hanging position moves to the rear side after moving downward, thereby moving to the 2 nd arrangement completion position. The 1 st holding wire guide 24 may be movable between the 1 st wire-hanging position and the 1 st arrangement completion position by being moved obliquely. Similarly, the 2 nd holding wire guide 25 can be moved between the 2 nd wire-hanging position and the 2 nd arrangement completion position by being moved obliquely.

In the above embodiment, the yarn processing device 7 has the interlocking mechanism 30 that interlocking the movement of the 1 st holding yarn guide 24 and the 2 nd holding yarn guide 25. However, the yarn processing device 7 may not have the interlocking mechanism 30. In this case, the movement of the 1 st holding wire guide 24 between the 1 st wire-hanging position and the 1 st arrangement completion position and the movement of the 2 nd holding wire guide 25 between the 2 nd wire-hanging position and the 2 nd arrangement completion position are performed independently, respectively.

In the above embodiment, the yarn is suspended from the yarn processing device 7 by using the suction gun 80. However, the yarn may be hung using a hook yarn guide that gathers the plurality of yarns Y together.

In the above embodiment, the 1 st holding wire guide 24 at the 1 st wire-hanging position and the 2 nd holding wire guide 25 at the 2 nd wire-hanging position are disposed at positions downstream of the 1 st limit wire guide 22 and upstream of the 2 nd limit wire guide 23 in the wire traveling direction. However, the 1 st holding guide 24 at the 1 st thread-hanging position and the 2 nd holding guide 25 at the 2 nd thread-hanging position may be disposed at a position upstream of the 1 st limiting guide 22 in the thread traveling direction or may be disposed at a position downstream of the 2 nd limiting guide 23 in the thread traveling direction.

In the above embodiment, the 1 st holding wire guide 24 that moves from the 1 st wire-hanging position toward the 1 st arrangement completion position is stopped when the 1 st arrangement completion position is reached. However, the 1 st holding wire guide 24 may be moved further beyond the 1 st arrangement completion position after reaching the 1 st arrangement completion position. For example, the 1 st holding yarn guide 24 may be moved beyond the 1 st arrangement completion position to the rear side of the yarn processing section 21. The same holds for the guide 25 of the 2 nd. That is, in the above embodiment, the 2 nd holding wire guide 25 that moves from the 2 nd wire-hanging position toward the 2 nd arrangement completion position is stopped when the 2 nd arrangement completion position is reached. However, the 2 nd holding wire guide 25 may be moved further beyond the 2 nd arrangement completion position after reaching the 2 nd arrangement completion position. For example, the 2 nd holding yarn guide 25 may be moved beyond the 2 nd arrangement completion position to the rear side of the yarn processing section 21.

In the above embodiment, the 1 st holding groove 24a may be formed over the entire circumference of the 1 st holding wire guide 24, or may be formed only in a part of the circumferential surface of the 1 st holding wire guide 24. However, the 1 st holding groove 24a needs to be configured so that each wire Y does not come out of the 1 st holding groove 24a during the movement of the 1 st holding guide 24 from the 1 st threading position to the 1 st arrangement completion position. Similarly, the 2 nd holding groove 25a may be formed over the entire circumference of the 2 nd holding wire guide 25, or may be formed only in a part of the circumferential surface of the 2 nd holding wire guide 25. However, the 2 nd holding groove 25a needs to be configured so that each wire Y does not come out of the 2 nd holding groove 25a during the movement of the 2 nd holding guide 25 from the 2 nd threading position to the 2 nd arrangement completion position.

In the above embodiment, the yarn processing device 7 is disposed below the plurality of guide yarn guides 6 in the spinning production facility 1 and above the godet roller 11. However, the position where the yarn processing device 7 is disposed is not limited to this. When the spacing between the plurality of wires on the upstream side and the downstream side in the wire traveling direction is different due to the wire-hanging operation using the suction gun 80 or the like, the configuration of the present invention can be effective when the wire Y is to be caught by two restriction guides (1 st restriction guide and 2 nd restriction guide) which are arranged separately in the wire traveling direction and have a plurality of grooves (1 st groove and 2 nd groove) having the same spacing in the arrangement direction.

In the above embodiment, the plurality of wires Y bundled toward the suction gun 80 as the bundling section are arranged in the plurality of wire travel spaces 31 formed in the wire processing section 21. That is, regarding the pitch of the plurality of wires Y in the arrangement direction, the pitch on the upstream side in the wire traveling direction is wider than the pitch on the downstream side. However, the pitch of the plurality of wires Y arranged in the plurality of wire travel spaces 31 in the arrangement direction may be narrower on the upstream side than on the downstream side in the wire travel direction.
