Waste silk box

Abstract

The present invention addresses the problem of suppressing noise. In the waste yarn box (40), a partition wall (50) with a ventilation hole (50A) is arranged in a box body (42), and the interior of the box body (42) is divided into a waste yarn collecting chamber (52) and an outlet chamber (54) through the partition wall (50). The box body (42) forming the waste yarn collecting chamber (52) is provided with an inflow cylinder part (56) for enabling the waste yarn (Y2) to flow into the waste yarn collecting chamber (52), and the box body (42) forming the outlet chamber (54) is provided with an exhaust port (58) for enabling compressed air separated from the waste yarn (Y2) to flow out. In addition, the exhaust port (58) is arranged on a wall part different from a left wall (42L) forming the outlet chamber (54), and the inflow cylinder part (56) is arranged on a wall part different from a right wall (42R) forming the waste yarn collecting chamber (52). Therefore, the sound caused by the sound absorption is repeatedly reflected in the waste silk box (40), so that the intensity of the sound leaked from the exhaust port (58) to the outside of the waste silk box (40) can be reduced. Therefore, the noise of the waste silk box (40) can be suppressed.

Description

Technical Field

[0001] The invention relates to a waste silk box. Background Art

[0002] In the spinning device described in Patent Document 1 below, an operator uses a suction device (suction gun) to guide the traveling yarn to the godet roller and the bobbin at the winding location. Specifically, the suction device is connected to a compressed air line for generating a suction flow. While the yarn is being sucked into the suction device, the yarn is guided to the godet roller and the bobbin. When the spinning device is operating, the spun yarn is pulled out by the godet roller and, after being stretched, is wound onto the bobbin at the winding location. Furthermore, a waste line is connected to the suction device, which is connected to a waste container (waste box) via the waste line. Thus, the waste yarn in the suction device is transported to the waste container along with the compressed air.

[0003] Prior art literature Patent Literature Patent Document 1: Japanese Patent Application No. 2020-502381 Summary of the Invention

[0004] Problems to be solved by the invention In the spinning device described above, as described above, the waste yarns in the suction device are conveyed to a disposal container along with compressed air and collected there. This creates a problem in that the sound generated by the suction operation of the suction device propagates to the disposal container, generating noise there. Therefore, it is desirable to have a structure that suppresses noise in the disposal container (waste box) that collects the waste yarns.

[0005] The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a waste box capable of suppressing noise.

[0006] Technical solutions to problems One or more embodiments of the present invention is a waste silk box that collects waste silk sucked by a suction part, and the waste silk box comprises: a box body, which is formed in a hollow box shape; a partition wall, which divides the interior of the box body into an inlet chamber and an outlet chamber, and has a plurality of ventilation holes that penetrate in the plate thickness direction and inhibit the passage of the waste silk; an inflow part, which is arranged in the box body constituting the inlet chamber and flows the waste silk into the interior of the inlet chamber; and an outflow part, which is arranged in the box body constituting the outlet chamber and allows the air separated from the waste silk to flow out from the outlet chamber, the inflow part and the outflow part are arranged on a wall part different from a wall part of the box body that is opposite to the partition wall in the plate thickness direction, and the interior of the box body is a space in which parts other than the inflow part and the outflow part are enclosed.

[0007] In the waste box structure described above, a partition with ventilation holes is provided inside the box, dividing the box into an inlet chamber and an outlet chamber. The box forming the inlet chamber is provided with an inlet portion for allowing waste to flow into the inlet chamber, and the box forming the outlet chamber is provided with an outflow portion for allowing air separated from the waste to flow out. Furthermore, the inflow and outflow portions are provided on separate walls of the box that are opposed to the partition in the thickness direction. This allows sound transmitted from the suction section into the waste box to be repeatedly reflected within the waste box, thereby reducing the intensity of sound leaking from the outflow portion to the outside of the waste box. Consequently, noise from the waste box can be suppressed.

[0008] One or more embodiments of the present invention provide a waste fiber box, wherein the partition walls are arranged with a direction perpendicular to a vertical direction serving as a plate thickness direction.

[0009] In the waste box structure described above, the partition walls are arranged with the thickness direction perpendicular to the vertical direction. Thus, the partition walls divide the interior of the box body perpendicular to the vertical direction. As a result, the lower wall of the box body forms the lower wall of the inlet chamber. For example, waste silk flowing into the inlet chamber can be effectively stored on the lower wall of the box body. Consequently, the partition walls can be installed within the waste box without hindering its waste collection function.

[0010] One or more embodiments of the present invention is a waste silk box, wherein the outflow portion is provided on a lower wall of the box body.

[0011] In the waste box structure described above, the outflow portion is located on the bottom wall of the box. This allows the sound inside the outlet chamber to escape from the outflow portion toward the space below the waste box. Consequently, when the box is placed on the floor, for example, the sound inside the outlet chamber can escape from the bottom wall of the waste box, which is typically located below the operator's head, toward the side opposite the operator's head. This further reduces noise from the waste box.

[0012] One or more embodiments of the present invention provide a waste silk box, wherein an opening area of ​​the outflow portion is set to be larger than an opening area of ​​the inflow portion.

[0013] In the waste box structured as described above, the opening area of ​​the outflow portion is set larger than the opening area of ​​the inflow portion. Therefore, compared to, for example, a case where the opening area of ​​the outflow portion is set smaller than the opening area of ​​the inflow portion, an increase in air resistance of air flowing from the inflow portion into the waste box and discharged from the outflow portion can be suppressed. Consequently, air separated from the waste by the partition wall can be discharged smoothly from the outflow portion.

[0014] One or more embodiments of the present invention is a waste silk box, wherein the box body is formed in a rectangular box shape, the partition wall is formed in a rectangular plate shape, and inside the box body, a pair of the partition walls are separately arranged in the plate thickness direction, and the interior of the box body is divided into the entrance chamber and a pair of the exit chambers by the pair of the partition walls, and the entrance chamber is arranged between the pair of the exit chambers.

[0015] In the waste box structure described above, a pair of partitions are provided within the box body, dividing the box body into an inlet chamber and a pair of outlet chambers. The inlet chamber is positioned between the pair of outlet chambers. This disperses sound leaking from the outlet of the outlet chambers, thereby further effectively suppressing noise from the waste box.

[0016] One or more embodiments of the present invention provide a waste silk box, wherein a sound absorbing member is provided in at least one of the inlet chamber and the outlet chamber.

[0017] In the waste box structured as described above, the sound absorbing member is provided in at least one of the inlet chamber and the outlet chamber, so that the sound inside the box can be absorbed by the sound absorbing member. This further reduces the intensity of the sound leaking from the outflow portion to the outside of the waste box.

[0018] One or more embodiments of the present invention provide a waste silk box, wherein the sound absorbing member is disposed at a position that does not block the inflow portion and the outflow portion.

[0019] In the waste box with the above structure, the sound absorbing member is arranged at a position that does not block the inlet and outlet parts, thereby preventing the waste from flowing from the inlet into the inlet chamber from being blocked and preventing the discharge of air from the outlet from being blocked.

[0020] One or more embodiments of the present invention provide a waste box, wherein the sound absorbing member covers an inner peripheral surface of a wall portion of the box body that faces the partition wall in a thickness direction, and is disposed adjacent to the inner peripheral surface.

[0021] In the waste box having the above structure, the sound absorbing member is disposed adjacent to the inner peripheral surface of the wall portion of the box body that faces the partition wall in the plate thickness direction. This can suppress a reduction in the volume of the inlet chamber or the outlet chamber.

[0022] One or more embodiments of the present invention provide a waste box, wherein the sound absorbing member covers an inner peripheral surface of a wall portion of the box body that faces the partition wall in a thickness direction and is disposed apart from the inner peripheral surface.

[0023] In one or more embodiments of the present invention, the sound-absorbing member is disposed separately from the inner circumferential surface of a wall portion of the box body that opposes the partition wall in the thickness direction. This creates an air layer between the wall portion and the sound-absorbing member. This allows the sound-absorbing band of the sound-absorbing member to be extended to lower frequencies relative to sounds generated within the waste box. This further enhances the sound-absorbing effect of the sound-absorbing member.

[0024] Effects of the Invention According to one or more embodiments of the present invention, noise can be suppressed. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] (First embodiment) Below, use Figures 1 to 3The waste box 40 according to the first embodiment will be described. The waste box 40 constitutes a portion of the spinning draw-off device 22 in the spinning system 10. Hereinafter, the spinning system 10 will be described first, and then the waste box 40 will be described.

[0034] (About Spinning System 10) like Figure 1 As shown, the spinning system 10 is a system for producing fully drawn yarn (FDY). The spinning system 10 includes a spinning device 12 and a spinning draw device 22. In the spinning device 12, melted raw material is fed from an extruder 14 to a gear pump 16. The raw material, pressure-fed by the gear pump 16, is extruded from a head 18, whereupon multiple spun yarns Y1 emerge from the spinning device 12. The multiple spun yarns Y1 emerging from the spinning device 12 are stretched by a stretching device 20 and then conveyed to the spinning draw device 22.

[0035] The spinning draw-off device 22 includes a guide mechanism 24 and a winding unit 26, with a bobbin 28 mounted on the winding unit 26. The spun yarn Y1 extending from the drawing device 20 is wound around the guide mechanism 24 and the bobbin 28 by a suction gun 30 serving as a suction unit. The spinning draw-off device 22 is operated, and the spun yarn Y1 passing through the guide mechanism 24 is wound around the bobbin 28.

[0036] The suction gun 30 is a well-known yarn suction unit that sucks and holds the spun yarn Y1 during the yarn-hanging operation (winding the spun yarn Y1 around the guide mechanism 24 and the bobbin 28). Specifically, a compressed air supply unit 32 is connected to the suction gun 30. Compressed air is supplied from the compressed air supply unit 32 to the suction gun 30, thereby sucking and holding the spun yarn Y1 through an air intake port provided at the front end of the suction gun 30. Furthermore, the suction gun 30 is connected to a waste yarn box 40 via a hose 34. After the yarn-hanging operation by the suction gun 30 is completed, the spun yarn Y1 is cut by a cutter, and the spun yarn Y1 in the suction gun 30 is conveyed to the waste yarn box 40 as waste yarn Y2 using compressed air and collected there.

[0037] (About waste box 40) Next, use Figure 2 and Figure 3 The waste box 40 will be described. Figure 2 and Figure 3 The arrows UP, FR, and RH shown appropriately in the figure respectively indicate the upper side, the front side, and the right side of the waste box 40. In the following description, when the up-down, front-back, and left-right directions are used for description, the up-down, front-back, and left-right directions of the waste box 40 are indicated unless otherwise specified.

[0038] The waste box 40 includes a box body 42 constituting an outer shell of the waste box 40 and a partition wall 50 provided inside the box body 42 .

[0039] The box 42 is shaped like a hollow, roughly rectangular parallelepiped. Four casters 44 are installed on the bottom surface of the box 42, near the four corners of the bottom wall 42D of the box 42. Each caster 44 has a roller 46 that is rotatable with the left and right axis as its axis. The casters 44 are placed on a floor or other installation surface to support the box 42 (waste box 40).

[0040] The partition wall 50 is formed into a generally rectangular plate with its thickness extending in the left-right direction. The partition wall 50 is located on the left end of the housing 42, with its outer periphery fixed to the inner periphery of the housing 42. Thus, the partition wall 50 divides the interior of the housing 42 into two sections, one on the left and the other on the right. Specifically, the portion of the housing 42 to the right of the partition wall 50 serves as the waste collection chamber 52, which serves as the entrance chamber, while the portion of the housing 42 to the left of the partition wall 50 serves as the exit chamber 54.

[0041] An inflow tube 56, serving as an inlet, is provided on the upper wall 42U of the housing 42, which forms the waste yarn collection chamber 52. Specifically, the inflow tube 56 is located on a wall portion different from the right wall 42R of the housing 42, which faces the partition wall 50 in the left-right direction (the thickness direction of the partition wall 50). The inflow tube 56 is formed into a generally cylindrical shape with the vertical direction as its axial direction, and protrudes upward from the upper wall 42U. The distal end of the hose 34 extending from the suction gun 30 is connected to the inflow tube 56. This allows the waste yarn Y2 conveyed from the suction gun 30 to flow into the waste yarn collection chamber 52 along with the compressed air.

[0042] The partition wall 50 has multiple circular ventilation holes 50A extending through it. The interior of the waste collection chamber 52 and the interior of the outlet chamber 54 are connected via the ventilation holes 50A. The ventilation holes 50A are arranged at predetermined intervals in the vertical and front-to-back directions of the partition wall 50. The diameters of the ventilation holes 50A are set so that the waste yarn Y2 flowing into the waste collection chamber 52 does not flow out toward the outlet chamber 54. In other words, the partition wall 50 serves as a wall portion that separates the compressed air flowing into the waste collection chamber 52 from the waste yarn Y2 and allows the separated air to pass toward the outlet chamber 54.

[0043] An exhaust port 58, serving as an outlet, is formed through the lower wall 42D of the housing 42, which forms the outlet chamber 54. Specifically, the exhaust port 58 is provided on a wall portion different from the left wall 42L of the housing 42, which faces the bulkhead 50 in the left-right direction (the thickness direction of the bulkhead 50). The opening area of ​​the exhaust port 58 is set to be larger than the opening area of ​​the inlet tube 56. Compressed air flowing out of the outlet chamber 54 is discharged from the exhaust port 58 to the exterior of the housing 42.

[0044] In addition, no openings other than the inflow tube 56 and the exhaust port 58 are formed in the box body 42. That is, the interior of the box body 42 is a closed space except for the inflow tube 56 and the exhaust port 58.

[0045] (Effect) Next, the operation and effects of this embodiment will be described.

[0046] In the waste yarn box 40 constructed as described above, the front end portion of the hose 34 extending from the suction gun 30 is connected to the inflow cylinder 56. As a result, the waste yarn Y2 sucked by the suction gun 30 flows into the waste yarn collection chamber 52 of the waste yarn box 40 together with the compressed air and is collected in the waste yarn collection chamber 52 (see Figure 3 ). Furthermore, the compressed air flowing into the waste yarn collection chamber 52 flows through the vent 50A in the partition wall 50 and into the outlet chamber 54. Furthermore, the size of the vent 50A prevents the waste yarn Y2 from passing through the vent 50A. The compressed air flowing into the outlet chamber 54 flows out of the waste yarn box 40 through the exhaust port 58. As a result, the compressed air flowing into the waste yarn box 40 and the waste yarn Y2 are separated by the waste yarn box 40, allowing the waste yarn Y2 to be collected in the waste yarn box 40.

[0047] However, the suction gun 30 uses the supplied compressed air to suck the waste yarn Y2, and the sucked waste yarn Y2 is conveyed to the inlet cylinder 56 of the waste box 40 via the hose 34. The waste yarn Y2 then flows from the inlet cylinder 56 into the waste box 40. As a result, the sound generated by the suction operation of the suction gun 30 (hereinafter referred to as suction sound) propagates from the inlet cylinder 56 into the waste box 40, potentially generating sound (noise) within the waste box 40 due to the suction sound.

[0048] In the waste box 40, a partition wall 50 having a vent hole 50A is provided within the box body 42. The partition wall 50 divides the interior of the box body 42 into a waste collection chamber 52 and an outlet chamber 54. Furthermore, the box body 42, which constitutes the waste collection chamber 52, is provided with an inlet tube 56 for allowing the waste yarn Y2 to flow into the waste collection chamber 52. The box body 42, which constitutes the outlet chamber 54, is formed with an exhaust port 58 for allowing compressed air separated from the waste yarn Y2 to flow out. Furthermore, the exhaust port 58 is provided on a wall portion of the box body 42 that is different from the left wall 42L that constitutes the outlet chamber 54, and the inlet tube 56 is provided on a wall portion of the box body 42 that is different from the right wall 42R that constitutes the waste collection chamber 52. This allows the sound caused by suction to be repeatedly reflected within the waste box 40, thereby reducing the intensity of the sound leaking from the exhaust port 58 to the outside of the waste box 40. Consequently, noise from the waste box 40 can be suppressed.

[0049] Below, on this point, Figure 4The waste yarn box 100 of the comparative example shown in FIG. 1 is described below. The waste yarn box 100 is constructed in the same manner as the waste yarn box 40 of the first embodiment except for the following points. Figure 4 In the figure, the same reference numerals are given to the parts having the same structure as the waste box 40 of the first embodiment. In the waste box 100 of the present embodiment, the partition wall 50 of the waste box 40 is omitted, and the interior of the box body 42 is composed only of the waste collection chamber 52. In addition, in the waste box 100 of the comparative example, the exhaust port 58 is omitted in the box body 42, and vent holes 50A are formed in the right wall 42R and the left wall 42L of the box body 42. The vent holes 50A are used to separate the waste yarn Y2 from the compressed air and discharge the compressed air to the outside of the waste box 100. Therefore, in the waste box 100 of the comparative example, the sound caused by the suction sound generated in the waste box 100 directly leaks to the outside of the waste box 100 through the vent holes 50A formed in the box body 42 (see Figure 4 As a result, the intensity of the sound leaking to the outside of the waste box 100 becomes relatively high, and there is a possibility that noise due to the suction sound will be generated in the waste box 100.

[0050] In contrast, in the waste box 40 of the first embodiment, a partition wall 50 having a vent hole 50A is provided within the box body 42. The partition wall 50 divides the interior of the box body 42 into a waste collection chamber 52 and an outlet chamber 54. Thus, the partition wall 50 can separate the compressed air from the waste yarn Y2, allowing the waste yarn Y2 to be collected in the waste collection chamber 52 while the compressed air flows toward the outlet chamber 54. Furthermore, the air flowing into the outlet chamber 54 can be discharged through the exhaust port 58.

[0051] In addition, in the waste box 40, the sound caused by the suction sound generated in the waste collection chamber 52 leaks out from the vent hole 50A of the adjacent wall 50 to the outlet chamber 54, and the sound leaked into the outlet chamber 54 is reflected by the inner peripheral surface of the outlet chamber 54. In particular, the sound reflected by the left wall 42L of the outlet chamber 54 leaks out from the vent hole 50A of the adjacent wall 50 to the waste collection chamber 52, and the sound leaked into the waste collection chamber 52 is reflected by the inner peripheral surface of the waste collection chamber 52. Furthermore, the sound reflected by the right wall 42R of the outlet chamber 54 leaks out from the vent hole 50A of the adjacent wall 50 to the outlet chamber 54. In this way, in the waste box 40, when the sound caused by the suction sound propagating from the suction gun 30 to the inflow cylinder 56 is generated in the waste box 40, the sound is repeatedly reflected between the left wall 42L and the right wall 42R in the waste box 40 (see Figure 3(as indicated by the arrows). Consequently, the distance that sound generated within the waste box 40 reaches the exhaust port 58 is increased. Furthermore, the sound within the waste box 40 is repeatedly reflected by the left and right walls 42L, 42R of the waste box 40, thereby increasing the amount of sound transmitted through the box body 42. As a result, the intensity of sound leaking from the exhaust port 58 to the outside of the waste box 40 can be reduced compared to the waste box 100 of the comparative example described above. Therefore, the waste box 40 of the first embodiment can suppress noise caused by suction sound.

[0052] As described above, the exhaust port 58 and the inlet tube 56 are located in a wall portion of the waste box 40 that is different from the wall portions located on both sides of the partition wall 50 in the plate thickness direction. In other words, the exhaust port 58 and the inlet tube 56 are located in a wall portion that is different from the left wall 42L and the right wall 42R, which function as reflective walls that primarily reflect sound toward the waste collection chamber 52 or the outlet chamber 54. This effectively reflects sound generated within the waste box 40 by the left wall 42L and the right wall 42R, and prevents sound that has passed through the vent hole 50A of the partition wall 50 from escaping directly from the exhaust port 58.

[0053] Furthermore, the partition wall 50 is formed into a generally rectangular plate with its thickness in the horizontal direction, and the partition wall 50 divides the interior of the box body 42 in the horizontal direction. Thus, the lower wall 42D of the box body 42 constitutes the lower wall of the waste yarn collection chamber 52. For example, waste yarn Y2 flowing into the waste yarn collection chamber 52 can be well stored on the lower wall 42D. Therefore, the partition wall 50 can be installed in the waste yarn box 40 without hindering the waste yarn Y2 collection function of the waste yarn box 40.

[0054] Furthermore, the exhaust port 58 is provided on the lower wall 42D of the box body 42, which forms the outlet chamber 54. Therefore, the sound within the outlet chamber 54 can escape from the exhaust port 58 toward the space below (on the installation surface side) the waste box 40. Consequently, the sound within the outlet chamber 54 can escape from the lower wall 42D of the waste box 40, which is generally located below the operator's head, toward the side opposite the operator's head. This further reduces noise from the waste box 40.

[0055] Furthermore, the opening area of ​​the exhaust port 58 is set to be larger than the opening area of ​​the inlet cylinder 56. Therefore, compared to, for example, a case where the opening area of ​​the exhaust port 58 is set to be smaller than the opening area of ​​the inlet cylinder 56, it is possible to suppress an increase in the air resistance of the compressed air flowing from the inlet cylinder 56 into the waste box 40 and discharged from the exhaust port 58. Consequently, the compressed air separated from the waste yarn Y2 by the partition wall 50 can be discharged smoothly from the exhaust port 58.

[0056] (Second embodiment) Next, use Figure 5 and Figure 6The waste yarn box 200 of the second embodiment will be described. The waste yarn box 200 of the second embodiment is configured similarly to the waste yarn box 40 of the first embodiment except for the following points. Figure 5 and Figure 6 In the drawings, the same reference numerals are given to the parts having the same configuration as those of the waste box 40 of the first embodiment.

[0057] Specifically, in the waste box 200, sound-absorbing members 202 are provided in the waste collection chamber 52 and the outlet chamber 54 of the box body 42. The sound-absorbing members 202 are formed into a generally rectangular plate shape, with the left-right direction being the plate thickness direction. The sound-absorbing members 202 in the waste collection chamber 52 are positioned adjacent to the right wall 42R of the box body 42, while the sound-absorbing members 202 in the outlet chamber 54 are positioned adjacent to the left wall 42L of the box body 42. This configuration prevents excessive reduction in the volume of the waste collection chamber 52 and the outlet chamber 54, even when the sound-absorbing members 202 are provided in the waste collection chamber 52 and the outlet chamber 54. Furthermore, the size of the sound-absorbing members 202, as viewed from the left-right direction, is set so that they cover substantially the entire inner circumference of the right wall 42R and the left wall 42L. Furthermore, in the outlet chamber 54, the exhaust port 58 is located to the right of the sound-absorbing member 202 within the outlet chamber 54 so that the sound-absorbing member 202 does not block the exhaust port 58. This configuration ensures that even if the sound-absorbing member 202 is located in the outlet chamber 54, the discharge of compressed air from the exhaust port 58 is not impeded. Furthermore, in the waste yarn collection chamber 52, the sound-absorbing member 202 is positioned so as not to block the inflow cylinder 56. This configuration ensures that even if the sound-absorbing member 202 is located in the waste yarn collection chamber 52, the inflow of waste yarn Y2 from the inflow cylinder 56 is not impeded.

[0058] The sound absorbing member 202 is made of a porous material having open cells, such as glass wool or rock wool, so that the vibration of the sound waves entering the sound absorbing member 202 is converted into heat energy by the sound absorbing member 202, thereby attenuating the sound inside the box 42.

[0059] Furthermore, in the waste box 200 of the second embodiment, as in the first embodiment, the partition wall 50 divides the interior of the box body 42 into a waste collection chamber 52 and an outlet chamber 54. Therefore, as in the first embodiment, in the waste box 200, the suction sound propagating from the suction gun 30 to the inlet cylinder 56 is repeatedly reflected between the left wall 42L and the right wall 42R within the waste box 40. This increases the distance that sound generated within the waste box 40 travels to the exhaust port 58, and increases the amount of sound transmitted through the box body 42. Therefore, in the second embodiment, the noise in the waste box 200 caused by suction sound can also be suppressed.

[0060] Furthermore, in the second embodiment, as described above, sound-absorbing members 202 are provided in each of the waste collection chamber 52 and the outlet chamber 54 of the waste box 200. Specifically, the sound-absorbing members 202 are arranged adjacent to the right and left walls 42R, 42L of the box body 42, covering the inner circumferential surfaces of the right and left walls 42R, 42L. Consequently, the sound within the box body 42 caused by the suction sound propagating from the suction gun 30 to the inflow tube 56 is absorbed by the sound-absorbing members 202. Consequently, the intensity of the sound escaping from the exhaust port 58 to the outside of the waste box 200 can be further reduced. Consequently, the noise in the waste box 200 caused by the suction sound can be effectively suppressed.

[0061] In the second embodiment, the sound-absorbing member 202 is disposed in both the waste collection chamber 52 and the outlet chamber 54 of the waste box 200. However, the sound-absorbing member 202 may be disposed in either the waste collection chamber 52 or the outlet chamber 54. In this case, the sound-absorbing member 202 can absorb the sound caused by the suction sound in the waste box 200. Furthermore, by disposing the sound-absorbing member 202 in either the waste collection chamber 52 or the outlet chamber 54, the cost of the waste box 200 can be reduced.

[0062] In the second embodiment, the sound-absorbing member 202 is positioned adjacent to the inner circumferential surfaces of the right and left walls 42R, 42L of the box body 42. However, the sound-absorbing member 202 may be positioned separately from the right and left walls 42R, 42L. Specifically, the position of the sound-absorbing member 202 may be modified to form an air layer between the right and left walls 42R, 42L and the sound-absorbing member 202. This allows the sound-absorbing band of the sound-absorbing member 202, which absorbs sound generated within the waste box 200 due to suction noise, to be expanded to a lower frequency band. Consequently, the sound-absorbing effect of the sound-absorbing member 202 can be further enhanced.

[0063] In addition, in the waste yarn box 40 and 200 of the first and second embodiments, a partition wall 50 is provided in the box body 42 to divide the box body 42 into the waste yarn collection chamber 52 and the outlet chamber 54. However, a pair of partition walls 50 may be provided in the box body 42 to divide the box body 42 by a pair of partition walls 50. Figure 7 An example in which a pair of partition walls 50 are provided in the waste box 40 of the first embodiment will be described as a modified example of the waste box 40 .

[0064] As shown in the figure, in this modified example of the waste box 40, partitions 50 are provided on the left and right sides of the box body 42. The area between the pair of partitions 50 in the box body 42 forms a waste collection chamber 52, and the areas on either side of the waste collection chamber 52 in the box body 42 form outlet chambers 54. Exhaust ports 58 are formed in the lower wall 42D of the box body 42, which constitute the outlet chambers 54. Specifically, two exhaust ports 58 are formed in the lower wall 42D of the waste box 40. The total opening area of ​​the two exhaust ports 58 is set to be greater than the opening area of ​​the inlet tube 56.

[0065] Furthermore, in the modified example of the waste box 40, the suction sound propagating from the suction gun 30 to the inlet tube 56 is repeatedly reflected between the left wall 42L and the right wall 42R within the waste box 40. This increases the distance that the sound generated within the waste box 40 reaches the exhaust port 58, thereby increasing the amount of sound transmitted through the box body 42. Consequently, in the modified example of the waste box 40, the intensity of sound leaking from the exhaust port 58 to the outside of the waste box 40 can also be reduced.

[0066] Furthermore, in this modified example of the waste box 40, two exhaust ports 58 are formed on the lower wall 42D of the box body 42. The combined opening area of ​​these two exhaust ports 58 is set to be larger than the opening area of ​​the inlet tube 56. Therefore, in this modified example of the waste box 40, the opening area of ​​the exhaust ports 58 can be set smaller than that of the first embodiment, and the exhaust ports 58 can be dispersed. This disperses sound escaping from the lower wall 42D of the box body 42 into the space below the waste box 40. Consequently, noise from the waste box 40 can be further effectively suppressed.

[0067] In the waste silk boxes 40 and 200 of the first and second embodiments, the inlet cylinder 56 is provided on the upper wall 42U of the box body 42, and the exhaust port 58 is provided on the lower wall 42D of the box body 42. However, the positions of the inlet cylinder 56 and the exhaust port 58 are not limited thereto. For example, the inlet cylinder 56 and the exhaust port 58 may be provided on the front wall or the rear wall of the box body 42. In other words, the inlet cylinder 56 and the exhaust port 58 may be provided on a wall portion of the box body 42 different from the left wall 42L and the right wall 42R.

[0068] In the waste yarn box 40 and 200 of the first and second embodiments, the partition wall 50 is formed into a substantially rectangular plate with the left-right direction as the plate thickness direction, dividing the box body 42 into the waste yarn collection chamber 52 and the outlet chamber 54, but the shape of the partition wall 50 is not limited thereto. Figure 8 As shown in (A), the partition wall 50 may be formed into a rectangular cylindrical shape with the vertical direction as the axial direction, and the box body 42 may be divided into a waste yarn collection chamber 52 and an outlet chamber 54. In addition, when the partition wall 50 is formed into a cylindrical shape, for example, Figure 8 As shown in FIG. 5B , the housing 42 may be formed into a hollow cylindrical box shape, and the partition wall 50 may be formed into a cylindrical shape with the vertical direction as the axial direction. Even with this configuration of the housing 42 and partition wall 50, as in the first and second embodiments, the waste yarn Y2 can be collected in the waste yarn collection chamber 52, and the inner circumferential surface of the outer wall of the housing 42 can reflect sound within the housing 42, thereby extending the propagation distance of sound within the housing 42.

[0069] Furthermore, the waste boxes 40 and 200 of the first and second embodiments are applied to a system for producing FDY. However, the waste boxes 40 and 200 may also be applied to a system for producing partially oriented yarn (POY) or a system for producing drawn textured yarn (DTY) by false twisting POY.

[0070] Furthermore, the suction guns 30 used in the spinning system 10 include not only the suction gun operated by the operator but also the suction gun constituting the yarn hanging robot.
