Description

Technical Field

[0001] This invention relates to a spinning production apparatus having a conduit surrounding a traveling filament. Background Technology

[0002] Previously, a spinning production apparatus was known, comprising a spinning device that spins high-temperature molten polymer as a filament downward from a spinning spinneret, a cooling device that supplies cooling air to the filament spun from the spinning device, and a winding device for winding the filament onto a bobbin support mounted below the cooling device. The spinning device and the cooling device are located in a spinning chamber, and the winding device is located on the floor of a winding chamber located below the spinning chamber.

[0003] The yarn traveling between the cooling device in the spinning chamber and the winding device in the winding chamber may wobble due to exposure to outside air. This leads to a deterioration in the yarn's ability to attach to the winding device and a reduction in the quality of the traveling yarn. Therefore, a conduit is provided between the cooling device in the spinning chamber and the winding device in the winding chamber to surround the traveling yarn and suppress its wobble.

[0004] Patent Document 1 discloses a spinning production apparatus in which a pipe is provided below a spinning bobbin (cooling device) connected to a pipe supplying cooling air. This pipe connects the spinning chamber and the winding chamber. The yarn spun from the spinning device, after being cooled by the cooling device, is introduced into the pipe from a yarn inlet at the upper end, travels within the pipe, and exits near the winding device from a yarn outlet at the lower end of the pipe. Furthermore, in addition to the aforementioned yarn inlet and yarn outlet, an exhaust port is provided on the pipe to discharge a portion of the air inside the pipe. Inside the pipe of the spinning production apparatus, air flows in from the yarn inlet along with the traveling yarn. When the amount of air flowing in is large, the airflow inside the pipe becomes turbulent, potentially causing the yarn to wobble. Therefore, it is highly necessary to provide an exhaust port on the pipe, in addition to the yarn inlet and yarn outlet, to discharge a portion of the air inside the pipe.

[0005] Patent Document 1: Japanese Patent Application Publication No. 50-118013

[0006] Here, a spinning chamber is provided in the spinning apparatus to convey and spin multiple filaments while maintaining the temperature of the high-temperature molten polymer. High-temperature air is generated in the spinning chamber due to heat dissipation from the spinning chamber. In addition, high-temperature air is generated due to heat exchange between the cooling air supplied to the filaments from the cooling device and the high-temperature molten polymer. This high-temperature air in the spinning chamber is conveyed downwards along with the filaments traveling inside the pipes and is discharged into the winding chamber from the filament outlet and the exhaust port.

[0007] In the spinning production equipment described in Patent Document 1, a work area is provided near the winding device located on the floor of the winding chamber for operators to perform various tasks such as yarn loading on the winding device. When the exhaust port of the pipeline is located close to the work area, high-temperature air flows into the work area from the exhaust port in addition to the yarn outlet. As a result, the temperature of the work area rises, leading to a deterioration of the operator's working environment. Summary of the Invention

[0008] The purpose of this invention is to prevent the deterioration of the working environment of the operator in the winding chamber due to the inflow of high-temperature air from the spinning chamber into the winding chamber through the inside of the pipe.

[0009] The spinning production equipment of the present invention is characterized by comprising: a spinning device disposed in a spinning chamber, which spins multiple filaments downward; a winding device disposed on the floor of a winding chamber located below the spinning chamber, which winds the multiple filaments spun by the spinning device into multiple bobbins mounted on a bobbin support; a partition plate, which is a component that separates the spinning chamber from the winding chamber and constitutes the floor of the spinning chamber and the ceiling of the winding chamber; and a conduit that connects the spinning chamber and the winding chamber to surround the multiple filaments. Extending downwards within the aforementioned winding chamber, a working area is provided below the lower end of the aforementioned pipe for an operator to perform prescribed operations on the aforementioned winding device. The aforementioned pipe has: a thread inlet at its upper end for guiding the aforementioned multiple threads inwards; a thread outlet at its lower end for guiding the aforementioned multiple threads outwards; and an exhaust port provided between the aforementioned thread inlet and the aforementioned thread outlet in such a way as to open into the aforementioned winding chamber. The lower end of the aforementioned exhaust port is positioned at a position more than 5m away from the aforementioned floor of the aforementioned winding chamber.

[0010] According to the present invention, the lower end of the exhaust port is positioned at a location more than 5 meters above the floor of the winding chamber. Therefore, a portion of the high-temperature air inside the pipe can be discharged at a position sufficiently separated from the floor of the winding chamber. This prevents high-temperature air from flowing into the work area located near the floor of the winding chamber, thus preventing the deterioration of the working environment for operators in the winding chamber.

[0011] Preferably, in this invention, the distance between the lower end of the exhaust port and the partition plate is within 1m.

[0012] According to the present invention, the distance between the lower end of the exhaust port and the partition plate constituting the ceiling of the winding chamber is within 1 meter. Therefore, a portion of the high-temperature air inside the pipe can be discharged near the ceiling of the winding chamber. This further suppresses the inflow of high-temperature air through the pipe into the work area, and prevents the deterioration of the working environment for operators in the winding chamber.

[0013] In this invention, it is preferable that the exhaust port is oriented in a direction orthogonal to the arrangement direction of the plurality of filaments.

[0014] The airflow generated when air is discharged from the vent affects the quality of the threads traveling inside the pipe. When the vent opens in a direction parallel to the arrangement direction of the multiple threads, the effect of the air discharged from the vent on the threads differs between the threads on one side of the arrangement direction and the threads on the other side. This can potentially cause quality differences among the multiple threads. According to the present invention, the vent opens in a direction orthogonal to the arrangement direction of the multiple threads. Therefore, the effect of the air discharged from the vent on the threads is approximately uniform between the threads on one side of the arrangement direction and the threads on the other side. This suppresses the possibility of quality differences among the multiple threads.

[0015] In this invention, it is preferred that, when viewed from a direction orthogonal to the above-mentioned arrangement direction, the exhaust port is formed to be a size that includes all of the above-mentioned multiple filaments along the above-mentioned arrangement direction.

[0016] According to the present invention, compared to the case where the exhaust port is formed to include only a portion of the multiple threads along the arrangement direction when viewed from a direction orthogonal to the arrangement direction, the effect of the air discharged from the exhaust port on the threads can be further uniform among the multiple threads. Therefore, it is possible to further suppress differences in the quality of the multiple threads.

[0017] Preferably, in this invention, the working area is located on one side of the pipe in the axial direction of the tube support, and the exhaust port opens towards the other side of the pipe in the axial direction of the tube support.

[0018] According to the present invention, a portion of the high-temperature air inside the pipe can be discharged through the exhaust port to the opposite side of the pipe, which is located in the work area where the operator is performing the prescribed work. Therefore, by discharging a portion of the high-temperature air to a location separate from the work area, the inflow of high-temperature air into the work area can be further suppressed.

[0019] Preferably, in this invention, the plurality of filaments are opened to the spinning chamber between the cooling device and the aforementioned pipe. The cooling device is disposed in the spinning chamber and supplies cooling air to the plurality of filaments spun from the spinning device below the spinning device.

[0020] In configurations where multiple filaments open into the spinning chamber between the cooling device and the pipes, more high-temperature air flows into the pipes from these open sections through the filament inlets. In this respect, in the configuration of the present invention, the exhaust port is located at a position separate from the floor of the winding chamber. Therefore, compared to a configuration where the exhaust port is located near the floor of the winding chamber, the resistance at the lower part of the pipe increases, and the static pressure inside the pipe rises. This helps to suppress the inflow of high-temperature air from the filament inlets into the pipes. Consequently, it further suppresses the inflow of high-temperature air into the working area through the pipes.

[0021] Preferably, in this invention, the pipe further includes an adjustment component capable of adjusting the opening area of ​​the exhaust port.

[0022] The larger the opening area of ​​the exhaust port, the greater the amount of high-temperature air that can be discharged from the exhaust port. On the other hand, when the opening area of ​​the exhaust port is large, the pressure inside the pipe decreases due to the air being discharged from the exhaust port, and the amount of high-temperature air flowing into the pipe from the yarn inlet also increases. Then, when the exhaust port has a specified opening area, the amount of high-temperature air flowing into the pipe from the yarn inlet and the amount of high-temperature air being discharged from the exhaust port are determined by the spinning speed, the type of yarn, etc. According to the present invention, the opening area of ​​the exhaust port can be adjusted. Therefore, it is possible to consider the balance between the high-temperature air flowing into the pipe from the yarn inlet and the high-temperature air discharged from the exhaust port into the winding chamber, and appropriately adjust the opening area of ​​the exhaust port to a value that can most effectively suppress the flow of high-temperature air into the working area based on the areas of the spinning chamber and the winding chamber.

[0048] (Spinning production equipment 1)

[0049] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a schematic side view of the spinning production equipment 1 according to this embodiment. Hereinafter, Figure 1 The front-back and up-down directions in the text are defined as the front-back and up-down directions of the spinning production equipment 1. Furthermore, the... Figure 1 The vertical direction of the paper surface is defined as the left-right direction of the spinning production equipment 1, and the surface of the paper surface is set as the right side.

[0050] like Figure 1As shown, the spinning production equipment 1 includes a spinning device 2, a cooling device 3, a spinning stretching device 4, a winding device 5, a pipe 6, multiple oil nozzles 7, multiple guide rollers 8, and guide rollers 9 and 10. The spinning device 2, cooling device 3, oil nozzles 7, and guide rollers 8 are disposed in the spinning chamber 101. The spinning stretching device 4, winding device 5, pipe 6, and guide rollers 9 and 10 are disposed in the winding chamber 102 located below the spinning chamber 101. Furthermore, the spinning production equipment 1 includes a partition plate 40 that separates the spinning chamber 101 from the winding chamber 102. The partition plate 40 constitutes part of the floor of the spinning chamber 101 and part of the ceiling 102b of the winding chamber 102. In this embodiment, the distance from the floor 102a of the winding chamber 102 to the ceiling 102b is approximately 6 to 7 meters.

[0051] The spinning apparatus 2 is a device that spins multiple filaments Y downwards. The spinning apparatus 2 includes a spinning box 21 for conveying molten polymer and a spinning spinneret 22 for spinning the molten polymer as filaments Y downwards. The spinning spinnerets 22 are arranged in a left-right direction. Therefore, the multiple filaments Y spun from the spinning spinnerets 22 are arranged in a left-right direction.

[0052] The cooling device 3 is located below the spinning device 2. The cooling device 3 is a device that cools the multiple filaments Y spun from the spinning device 2 by supplying cooling air to the filaments Y. The cooling device 3 has a generally cylindrical cooling cylinder 31 with openings at both ends in the vertical direction. Inside the cooling cylinder 31, the multiple filaments Y can travel from top to bottom, and the cooling device 3 supplies cooling air to the multiple filaments Y traveling inside the cooling cylinder 31.

[0053] Multiple oil nozzles 7 are arranged below the cooling device 3 to apply oil to the multiple filaments Y after they have been cooled by the cooling device 3. Multiple guides 8 are arranged at equal intervals in the left-right direction below each of the multiple oil nozzles 7 to guide the multiple filaments Y that have been coated with oil independently.

[0054] The conduit 6 connects the spinning chamber 101 and the winding chamber 102, extending downwards within the winding chamber 102 in a manner that surrounds multiple filaments Y. Details regarding the conduit 6 will be described later.

[0055] Furthermore, in this embodiment, the front sides of the plurality of filaments Y are open to the spinning chamber 101 between the cooling device 3 and the pipe 6. Additionally, a plate-shaped member 41 with multiple holes is disposed on the rear side of the plurality of filaments Y traveling between the cooling device 3 and the pipe 6. Therefore, the rear sides of the plurality of filaments Y are partially open to the spinning chamber 101 via the multiple holes formed in the plate-shaped member 41 between the cooling device 3 and the pipe 6. Also, although not shown, sidewalls are formed on the left and right sides of the plurality of filaments Y traveling between the cooling device 3 and the pipe 6. Therefore, the configuration between the cooling device 3 and the pipe 6 is such that the right and left sides of the plurality of filaments Y are not open to the spinning chamber 101.

[0056] Furthermore, similar to the multiple yarns Y, the front sides of the multiple oil nozzles 7 and multiple yarn guides 8 between the cooling device 3 and the pipe 6 open towards the spinning chamber 101. Additionally, the rear sides of the multiple oil nozzles 7 and multiple yarn guides 8 between the cooling device 3 and the pipe 6 partially open towards the spinning chamber 101 via multiple holes formed in the plate-shaped member 41. Moreover, the right and left sides of the multiple oil nozzles 7 and multiple yarn guides 8 between the cooling device 3 and the pipe 6 do not open towards the spinning chamber 101.

[0057] The spinning and stretching device 4 is located below the pipe 6. The spinning and stretching device 4 is a device that heats and stretches multiple filaments Y by means of multiple guide rollers (not shown) housed inside an insulated box (not shown).

[0058] Multiple filaments Y, stretched by the spinning and stretching device 4, are conveyed to the winding device 5 via guide rollers 9 and 10. The winding device 5 is a device for winding the multiple filaments Y and is located on the floor 102a of the winding chamber 102.

[0059] The winding device 5 winds multiple yarns Y onto multiple bobbins B held by the bobbin holders 11, forming multiple packages P. Two bobbin holders 11 are provided in the winding device 5. Each bobbin holder 11 is a shaft member extending in the front-to-back direction, its rear end cantilevered by a turntable 13 mounted on the machine body 12. The bobbin holders 11 can hold multiple bobbins B in an axial arrangement. For example, when eight yarns Y are fed from the spinning device 2, the eight yarns Y are wound onto eight bobbins B.

[0060] Furthermore, the take-up device 5 includes multiple support guides 14, multiple traverse devices 15, and contact rollers 16. The multiple support guides 14 and multiple traverse devices 15 are arranged in the front-to-back direction corresponding to the multiple bobbins B held by the bobbin support 11. Each traverse device 15 reciprocates the yarn Y in the front-to-back direction around its corresponding support guide 14. The contact rollers 16 contact the surfaces of the multiple packages P and apply a predetermined contact pressure to adjust the shape of the packages P.

[0061] In addition, such as Figure 1 As shown, a work area W is provided below the lower end of the pipe 6 for operator A to perform prescribed operations on the spinning and stretching device 4 and the winding device 5. Work area W is the area for operator A, standing on a worktable 51 located on the floor 102a of the winding chamber 102, to perform prescribed operations. Prescribed operations include, for example, the operation of attaching yarn to the multiple guide rollers (not shown) of the spinning and stretching device 4, and a yarn unwinding device (not shown).

[0062] The working area W is located on the front side of the pipe 6 (corresponding to "one side of the pipe" in this invention) in the axial direction (front-back direction) of the pipe support 11. In this embodiment, the winding device 5 is located on the rear side of the pipe 6. Thus, the working area W is positioned on the opposite side of the winding device 5, clamping the pipe 6.

[0063] (Pipe 6)

[0064] The following is a detailed description of the structure of pipe 6. Figure 1 as well as Figure 2 As shown, pipe 6 is a roughly rectangular parallelepiped-shaped component extending vertically. The cross-section of pipe 6, orthogonal to its extension direction, is rectangular, with the longer side extending horizontally and the shorter side extending vertically. The upper part of pipe 6 is fixed by a partition plate 40. Figure 1 as well as Figure 2 As shown, pipe 6 has a wire inlet 61, a wire outlet 62, and an exhaust port 63.

[0065] The thread inlet 61 is a part used to guide multiple threads Y into the interior of the pipe 6 from the upper end of the pipe 6. The thread inlet 61 of the pipe 6 is connected to the partition plate 40. The multiple threads Y traveling below the cooling device 3 in the spinning chamber 101 are guided into the interior of the pipe 6 through the thread inlet 61.

[0066] The thread outlet 62 is a portion used to guide multiple threads Y from inside the pipe 6 to the winding chamber 102 at the lower end of the pipe 6. The thread outlet 62 is located above the spinning and stretching device 4. The multiple threads Y traveling inside the pipe 6 are guided out of the pipe 6 through the thread outlet 62. The distance between the ground 102a of the winding chamber 102 and the thread outlet 62 is approximately 3m.

[0067] like Figure 1As shown, the vent 63 is configured to open into the winding chamber 102 between the wire inlet 61 and the wire outlet 62. The lower end of the vent 63 is positioned at a position more than 5m away from the ground 102a of the winding chamber 102. Furthermore, the distance between the lower end of the vent 63 and the partition plate 40 is less than 1m. In this embodiment, the distance between the lower end of the vent 63 and the partition plate 40 is 550mm. Then, the vent 63 opens in a direction orthogonal to the arrangement direction of the multiple wires Y traveling inside the pipe 6, i.e., the front-to-back direction. In addition, the vent 63 opens towards the rear side of the pipe 6 (corresponding to the "other side of the pipe" in this invention) in the axial direction of the bobbin support 11, i.e., the front-to-back direction.

[0068] Furthermore, the exhaust port 63 is sized such that, when viewed from a direction orthogonal to the arrangement direction of the multiple threads Y, i.e., the front-back direction, it encompasses all the multiple threads Y along the left-right direction. Specifically, the exhaust port 63 in this embodiment has a vertical length of 250 mm and a horizontal length of 1320 mm.

[0069] In addition, such as Figure 2 As shown, the exhaust port 63 has multiple small holes 63a. The diameter of the small holes 63a is 55 mm. Figure 2 As shown, the small holes 63a are arranged in a row of 22 in the left-right direction and in 4 segments in the top-bottom direction, for a total of 88 holes. Air inside the pipe 6 is discharged to the winding chamber 102 through each small hole 63a. Furthermore, in this embodiment, the size of the exhaust port 63, which includes all the small holes 63a, is such that, when viewed from the front-back direction, it is the size that completely encompasses multiple filaments Y along the left-right direction.

[0070] like Figure 2 As shown, the pipe 6 also has an adjusting member 64 capable of adjusting the opening area of ​​the exhaust port 63. The adjusting member 64 is disposed on the inner side of the pipe 6 and above the exhaust port 63. The adjusting member 64 is a sliding gate capable of moving vertically. The vertical and horizontal dimensions of the adjusting member 64 are slightly larger than the exhaust port 63. The adjusting member 64 is adjusted by... Figure 2 The state moves downward, thereby covering a portion of the exhaust port 63. Thus, the adjusting member 64 can adjust the opening area of ​​the exhaust port 63.

[0071] In this embodiment, no vent is formed at the lower part of the pipe 6. More specifically, the pipe 6, except for the yarn outlet 62 and the vent 63, does not have any portion opening into the winding chamber 102. That is, the high-temperature air inside the pipe 6 will not be discharged into the winding chamber 102 from any part other than the yarn outlet 62 and the vent 63. Therefore, it is possible to prevent the high-temperature air in the spinning chamber 101 from flowing into the working area W of the winding chamber 102 through the pipe 6. Furthermore, in this embodiment, the vent 63 is configured to discharge the air inside the pipe 6 without drawing the air inside the pipe 6 to the outside. That is, the vent 63 is configured to only open into the winding chamber 102. At the vent 63, the air inside the pipe 6 is not drawn to the outside, thus preventing the pipe 6 from becoming negatively pressured. As a result, it is possible to prevent the high-temperature air in the spinning chamber 101 from flowing into the pipe 6 from the yarn inlet 61.

[0072] (Example)

[0073] Next, in the spinning production equipment 1 of the embodiment and comparative example, the inflow rate (m) of air into the pipe is... 3 / min) and the air discharge rate (m) from inside the pipe to the winding chamber 102. 3 The airflow rate was compared with that of the spinneret ( / min). Regarding the airflow into the pipe, the amount of air flowing into the pipe through the yarn inlet at the portion open from the front of the multiple yarns Y towards the spinning chamber 101 between the cooling device 3 and the pipe was measured. Furthermore, regarding the airflow from the pipe to the winding chamber 102, the airflow from the yarn outlet to the winding chamber 102 and the airflow from the exhaust port to the winding chamber 102 were measured respectively. The measurement results are in... Figure 4 The Chinese side indicated that...

[0074] The spinning production equipment 1 in this embodiment has the same configuration as the one described in the above embodiment. In this embodiment, the adjusting member 64 is positioned so as not to cover the exhaust port 63. Figure 2 (State).

[0075] The comparative example spinning production equipment 1 is configured the same as the embodiment, except for the piping. Figure 3As shown, the comparative example pipe 106 has a wire inlet 161, a wire outlet 162, and an exhaust port 163. The wire inlet 161 and wire outlet 162 have the same configuration as the wire inlet 61 and wire outlet 62 of the pipe 6 in the embodiment. That is, the wire inlet 161 is connected to the partition plate 40, and the distance between the wire outlet 162 and the ground 102a is 3.5m. The exhaust port 163 is formed at the lower part of the pipe 106. The exhaust port 163 opens towards the rear side of the pipe 106. The vertical and horizontal dimensions of the exhaust port 163 are the same as those of the exhaust port 63 of the pipe 6. Furthermore, the exhaust port 163, like the exhaust port 63, has 88 small holes 163a with a diameter of 55mm.

[0076] like Figure 4 As shown, in the comparative example, the air inflow rate into the pipe 106 was 15.9 (m³). 3 / min), while in the embodiment, the air inflow rate into the pipe 6 is 8.3 (m³ / min). 3 / min). That is, in the embodiment, compared with the comparative example, the inflow of high-temperature air from the spinning chamber 101 into the pipe 6 can be suppressed. It can be assumed that the reason is that, in the embodiment, since the exhaust port 63 is located at a position far away from the ground 102a of the winding chamber 102, the static pressure inside the pipe 6 increases, which can suppress the inflow of air from the open portion of the multiple filaments Y into the pipe 6.

[0077] In addition, such as Figure 4 As shown, in both the embodiment and the comparative example, the amount of air discharged from the yarn outlet 62 (162) to the winding chamber 102 is almost the same. On the other hand, the amount of air discharged from the exhaust port 63 to the winding chamber 102 in the embodiment is lower than the amount of air discharged from the exhaust port 163 to the winding chamber 102 in the comparative example. Specifically, in the embodiment, the amount of air discharged from the exhaust port 63 to the winding chamber 102 is 6.2 (m³). 3 / min), in the comparative example, the air discharge rate from exhaust port 163 to entrainment chamber 102 is 13.1 (m³ / min). 3 / min). It can be assumed that the reason is that, in the embodiment, as described above, as the inflow of air from the wire inlet 61 into the interior of the pipe 6 is suppressed, the outflow of air from the exhaust port 63 is also reduced.

[0078] Furthermore, in the comparative example, the exhaust port 163 is located at the lower part of the pipe 106, so the air discharged from the exhaust port 163 into the winding chamber 102 flows into the working area W. In contrast, in the embodiment, the exhaust port 63 is located at a position far from the ground 102a, so the air discharged from the exhaust port 63 into the winding chamber 102 is less likely to flow into the working area W. Thus, in the embodiment, compared with the comparative example, it is possible to suppress the flow of high-temperature air from the spinning chamber 101 into the working area W.

[0079] (Effect)

[0080] The spinning production equipment 1 of this embodiment includes a spinning device 2 and a cooling device 3 installed in a spinning chamber 101, a winding device 5 installed on the floor 102a of a winding chamber 102, a partition plate 40, and a pipe 6. The pipe 6 connects the spinning chamber 101 and the winding chamber 102 and extends downward in the winding chamber 102 in a manner that surrounds multiple filaments Y. A working area W is provided below the lower end of the pipe 6. The pipe 6 has a filament inlet 61 at its upper end for guiding multiple filaments Y inward, a filament outlet 62 at its lower end for guiding multiple filaments Y outward, and an exhaust port 63 between the filament inlet 61 and the filament outlet 62 that opens into the winding chamber 102. The lower end of the exhaust port 63 is positioned at a position more than 5m away from the floor 102a of the winding chamber 102.

[0081] According to this embodiment, the lower end of the exhaust port 63 is located at a position more than 5m away from the ground 102a of the winding chamber 102. Therefore, a portion of the high-temperature air inside the pipe 6 can be discharged at a position sufficiently separated from the ground 102a of the winding chamber 102. As a result, the inflow of high-temperature air through the inside of the pipe 6 into the work area W located near the ground 102a of the winding chamber 102 can be suppressed, and the deterioration of the working environment of the operator A in the winding chamber 102 can be prevented.

[0082] Furthermore, in this embodiment, the distance between the lower end of the exhaust port 63 and the partition plate 40 constituting the ceiling 102b of the winding chamber 102 is within 1 meter. Therefore, a portion of the high-temperature air inside the pipe 6 can be discharged near the ceiling 102b of the winding chamber 102. As a result, the inflow of high-temperature air through the inside of the pipe 6 into the work area W can be further suppressed, and the deterioration of the working environment of the operator A in the winding chamber 102 can be prevented.

[0083] Furthermore, in this embodiment, the exhaust port 63 opens in a direction orthogonal to the arrangement direction (left-right direction) of the multiple filaments Y. The airflow generated when air is discharged from the exhaust port 63 affects the quality of the filaments Y traveling inside the pipe 6. When the exhaust port 63 opens in a direction parallel to the arrangement direction of the multiple filaments Y, the effect of the air discharged from the exhaust port 63 on the filaments Y becomes different between the filaments Y on one side (right) and the filaments Y on the other side (left). Thus, quality differences may occur among the multiple filaments Y. According to this embodiment, the exhaust port 63 opens in a direction orthogonal to the arrangement direction of the multiple filaments Y. Therefore, the effect of the air discharged from the exhaust port 63 on the filaments Y becomes approximately uniform between the filaments Y on one side (right) and the filaments Y on the other side (left). As a result, quality differences among the multiple filaments Y can be suppressed.

[0084] Furthermore, in this embodiment, the exhaust port 63 is sized such that, when viewed from a direction orthogonal to the arrangement direction (left-right direction) of the multiple threads Y, it completely encompasses all the multiple threads Y along the arrangement direction (left-right direction). According to this embodiment, compared to the case where the exhaust port 63 is sized to encompass only a portion of the multiple threads Y along the left-right direction when viewed from the front-back direction, the effect of the air discharged from the exhaust port 63 on the threads Y can be further made more uniform among the multiple threads Y. Therefore, it is possible to further suppress differences in the quality of the multiple threads Y.

[0085] Furthermore, in this embodiment, the working area W is located on the front side of the pipe 6 in the axial direction (front-back direction) of the pipe support 11, and the exhaust port 63 opens towards the rear side of the pipe 6 in the axial direction (front-back direction) of the pipe support 11. According to this embodiment, a portion of the high-temperature air inside the pipe 6 can be discharged through the exhaust port 63 to the side opposite to the working area W where the operator A performs the prescribed work. Therefore, a portion of the high-temperature air can be discharged away from the working area W, further suppressing the inflow of high-temperature air into the working area W.

[0086] Furthermore, in this embodiment, multiple yarns Y are open to the spinning chamber 101 between the cooling device 3 and the pipe 6. In this configuration, more high-temperature air flows into the pipe 6 from the open portion. Regarding this, in this embodiment, since the exhaust port 63 is located at a position separated from the floor 102a of the winding chamber 102, the static pressure inside the pipe 6 increases, which can suppress the inflow of high-temperature air into the pipe 6 from the open portion of the multiple yarns Y. Therefore, it is possible to further suppress the inflow of high-temperature air into the working area W through the inside of the pipe 6.

[0087] Furthermore, in this embodiment, the pipe 6 also includes an adjustment member 64 capable of adjusting the opening area of ​​the exhaust port 63. The larger the opening area of ​​the exhaust port 63, the greater the amount of high-temperature air that can be discharged from it. On the other hand, when the opening area of ​​the exhaust port 63 is large, the pressure inside the pipe 6 decreases due to the air being discharged from the exhaust port 63, and the amount of high-temperature air flowing into the pipe 6 from the yarn inlet 61 also increases. Then, when the exhaust port 63 has a predetermined opening area, the inflow amount of high-temperature air flowing into the pipe 6 from the yarn inlet 61 and the discharge amount of high-temperature air from the exhaust port 63 are determined by the areas of the spinning chamber 101 and the winding chamber 102, etc. According to this embodiment, the opening area of ​​the exhaust port 63 can be adjusted. Therefore, the balance between the high-temperature air flowing into the pipe 6 from the yarn inlet 61 and the high-temperature air discharged from the exhaust port 63 to the winding chamber 102 can be considered. Based on the area of ​​the spinning chamber 101 and the winding chamber 102, the opening area of ​​the exhaust port 63 can be appropriately adjusted to a value that can most effectively suppress the high-temperature air flowing into the working area W.

[0088] (Modified Example)

[0089] The following describes variations of the above-described embodiments. Wherein, parts having the same structure as the above-described embodiments are given the same reference numerals and their descriptions are omitted as appropriate.

[0090] The spinning production apparatus 1 of the above embodiment is configured such that the arrangement direction of the spinning spinnerets 22 is orthogonal to the axial direction of the bobbin support 11. Then, the exhaust port 63 opens in a direction orthogonal to the arrangement direction of the multiple filaments Y, and simultaneously opens in the axial direction of the bobbin support 11. However, the spinning production apparatus 1 may also be configured such that the arrangement direction of the spinning spinnerets 22 is parallel to the axial direction of the bobbin support 11. In this case, the exhaust port 63 may also open in a direction orthogonal to the arrangement direction of the multiple filaments Y, and simultaneously open in a direction orthogonal to the axial direction of the bobbin support 11. Alternatively, the exhaust port 63 may open in a direction parallel to the arrangement direction of the multiple filaments Y, and simultaneously open in the axial direction of the bobbin support 11.

[0091] In the above embodiment, the vent 63 opens toward the winding chamber 102 in a direction orthogonal to the arrangement direction of the plurality of filaments Y. That is, the vent 63 opens on the side surface of the rear side of the pipe 6. However, the vent 63 may open on any one side surface of the pipe 6, or it may open on two or more sides.

[0092] In the above embodiment, the distance between the lower end of the exhaust port 63 and the partition plate 40 is within 1m. However, the distance between the lower end of the exhaust port 63 and the partition plate 40 may also be greater than 1m. In this case, the lower end of the exhaust port 63 is positioned at a position more than 5m away from the ground 102a of the winding chamber 102.

[0093] Furthermore, in the above embodiment, the exhaust port 63 may not have multiple small holes 63a. In this case, for example, the exhaust port 63 may be a single opening. Additionally, in the above embodiment, an opening of a size that does not obstruct the air discharge from the exhaust port 63 may be provided at any location on the pipe 6.

[0094] In the above embodiment, the wire inlet 61 of the pipe 6 is connected to the partition plate 40. However, the wire inlet 61 may also be located above the partition plate 40.

[0095] In the above embodiments, the cross-section of the pipe 6 orthogonal to the extension direction can also be circular or elliptical. Furthermore, the pipe 6 can also be bent midway.

[0096] In the above embodiment, multiple filaments Y are open to the spinning chamber 101 between the cooling device 3 and the pipe 6. However, the multiple filaments Y may not be open to the spinning chamber 101 between the cooling device 3 and the pipe 6. In this case, for example, the lower end of the cooling device 3 may be directly connected to the upper end of the pipe 6.

[0097] Furthermore, between the cooling device 3 and the pipe 6, the right and left sides of the multiple filaments Y can be open to the spinning chamber 101. However, when the right and left sides of the multiple filaments Y are open to the spinning chamber 101, the effect of the air flowing into the spinning chamber 101 through the open portion on the multiple filaments Y may be uneven. Therefore, it is preferable to close the right and left sides in the direction parallel to the filament arrangement direction, i.e., the left-right direction, and leave the front or back side or both sides in the direction orthogonal to the filament arrangement direction, i.e., the front-back direction, open to the spinning chamber 101.

[0098] In the above embodiment, the adjusting member 64 is a sliding gate capable of moving in the vertical direction. However, the adjusting member 64 may also be a sliding gate capable of moving in the horizontal direction. Furthermore, the adjusting member 64 is not limited to a sliding gate; for example, it may be a component that can be detached from the exhaust port 63. Additionally, in the above embodiment, the adjusting member 64 may not be provided.

[0099] In the above embodiment, the work area W is located on the front side of the pipe 6. However, the work area W can also be located on any side of the pipe 6, such as the right side, left side, rear side, diagonally right front side, diagonally left front side, diagonally right rear side, or diagonally left rear side. Furthermore, the work area W can be located at multiple positions covering the front, rear, right, left, diagonally right front side, diagonally left front side, diagonally right rear side, or diagonally left rear side of the pipe 6. Also, in the above embodiment, the workbench 51 may not be provided. In this case, the work area W is defined as the area for the operator A, located on the ground 102a, to perform a specified task. In this case, the specified task may include threading multiple threads Y of the guide rollers 9 and 10, the guide roller 14 supporting the winding device 5, and replacing the bobbin B on the bobbin support 11 of the winding device 5. In summary, the work area W is not limited to the workbench 51, and can also be the ground 102a surrounding the pipe 6 when viewed from above or below, or the area surrounding the workbench 51.
