Description

[Technical field]

[0001] The present invention relates to a yarn take-off device that takes up yarn spun from a spinning machine. [Background technology]

[0002] For example, Patent Document 1 discloses a spinning winder including a godet roller rotated by a motor and a winding device disposed below the godet roller. The godet roller takes up multiple yarns spun from the spinning machine and sends them downstream in the yarn running direction. When the winding process starts, the winding device winds the multiple yarns sent from the godet roller onto bobbins to form a package.

[0003] Before the winding process in the winding device starts, a winding operation is performed in which the yarn is wound around a godet roller by an operator holding a plurality of yarns by suction with a suction gun and winding the yarn around a godet roller or the like. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2021-050440 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, the suction gun is not only heavy for the operator, but also has a force that sucks the yarn. Therefore, it is difficult to wind the yarn without the suction gun touching the godet roller. If the suction gun touches the godet roller during winding, there is a risk of damaging the surface of the godet roller. In addition, the winding operation is not necessarily safe.

[0006] The present invention has been made in consideration of the above problems, and aims to provide a yarn take-up device that makes it easy to wind yarn, prevents damage to the godet roller, and improves safety. [Means for solving the problem]

[0007] (1) The spinning take-up device of the present invention is A support member; One end of the fiber spun from the fiber spinning device is supported by the support member, and the one end of the fiber spun from the fiber spinning device is supported by the support member. The plurality of threads are wound at a winding angle of less than 360 degrees, a godet roller which sends the wound yarns downstream in a yarn running direction; a winding assist member that assists in winding the plurality of yarns around the godet roller, The winding auxiliary member is a winding guide portion disposed radially outward from a roller surface of the godet roller; A fixing portion that fixes the wrapping guide portion to the support member, Among the regions in the axial direction of the godet roller, a region around which the plurality of yarns are wound is defined as a first axial region, a region closer to the one end side than the first axial region is defined as a second axial region, and a region closer to the other end side, which is opposite to the one end side than the first axial region is defined as a third axial region, Among the regions in the circumferential direction of the godet roller, a region between an introduction portion where the plurality of yarns are introduced into the godet roller and an outlet portion where the plurality of yarns are outlet from the godet roller and on a side where the plurality of yarns are wound around the godet roller is defined as a circumferential first region, and a region on a side where the plurality of yarns are not wound around the godet roller is defined as a circumferential second region. The wrapping guide portion has a side portion facing the support member in at least the circumferential first region in the circumferential direction of the wrapping guide portion, and is provided in at least the axial third region, The fixing portion is provided such that at least a portion of the axial first region is provided in the circumferential second region in the axial direction of the fixing portion.

[0008] According to the spinning take-off device described in (1) above, by pressing the tip of the suction gun against the winding guide part from the axial third region side, and then moving the suction gun along the winding guide part, it is possible to introduce multiple yarns and wind them around the godet roller so that the suction gun does not come into contact with the godet roller. Moreover, since the winding guide part has a side part facing the support member, there is nothing between the winding guide part and the support member to block the winding of the yarns, and further, the part of the axial first region of the fixed part is provided in the circumferential second region in the axial direction. Therefore, by moving the suction gun along the winding guide part, it is possible to easily wind the yarns around the godet roller without the suction gun coming into contact with the fixed part, and a spinning take-off device with excellent workability and safety can be provided.

[0009] In addition, if at least the first circumferential region of the winding guide portion is provided in the third axial region, the yarns can be wound around the godet roller so that the suction gun does not contact the godet roller. However, the second circumferential region of the winding guide portion may be provided in the third axial region.

[0010] In addition, if at least a portion of the first axial region of the fixed part is provided in the second circumferential region in the axial direction, the fixed part can be prevented from coming into contact with a plurality of threads. Therefore, the portion of the second region and the portion of the third region of the fixed part in the axial direction may be provided in either the first circumferential region or the second circumferential region.

[0011] (2) In the spinning take-up device of the present invention, the winding guide portion includes a second extending surface extending from the axial third region toward the axial first region radially outward of a roller surface of the godet roller, It is preferable that the side portion is a side portion of the other-side extending surface and forms a gap through which the plurality of yarns are introduced into the godet roller.

[0012] According to the spinning take-up device described above in (2), the strength of the winding guide portion can be increased by including the other-side extension surface, and stability can be maintained when the tip of the suction gun is pressed against the winding guide portion to move the suction gun.

[0013] In addition, the gap may be formed between the side of the other-side extending surface and the support member, or if there is another member between the other-side extending surface and the support member, the gap may be formed between the side of the other-side extending surface and the other member.

[0014] (3) In the spinning take-up device of the present invention, the fixing portion includes a one-side extending surface extending from the axial second region toward the axial first region radially outward of a roller surface of the godet roller, The one-side extending surface has a side portion facing away from the support member, It is preferable that a side portion of the one-side extending surface forms a gap through which the plurality of yarns are introduced into the godet roller.

[0015] According to the spinning take-up device described in (3) above, since the fixing part includes the one-side extending surface, the fixing part can be stably fixed to the support member.

[0016] The gap may be formed between the side of the one-side extending surface and the winding introduction portion, or, if there is another member between the one-side extending surface and the winding introduction portion, between the side of the one-side extending surface and the other member. Also, if the winding guide portion includes the other-side extending surface, a gap may be formed between the side of the one-side extending surface and the side of the other-side extending surface.

[0017] Furthermore, when the winding guide portion includes a other-side extending surface and the fixed portion includes a one-side extending surface, it is preferable that the one-side extending surface and the other-side extending surface are on the same plane, but it is not essential that the one-side extending surface and the other-side extending surface are on the same plane, and for example, there may be a step between the one-side extending surface and the other-side extending surface.

[0018] (4) In the spinning take-up device of the present invention, it is preferable that the winding guide portion and the fixed portion are formed in an annular shape, and the annular fixed portion and the annular winding guide portion form a tubular member for inserting the godet roller therearound.

[0019] (4) In the spinning take-up device of the present invention, It is preferable that the winding guide portion and the fixed portion are formed in an annular shape, and the annular fixed portion and the annular winding guide portion form a tubular member for inserting the godet roller therearound.

[0020] According to the spinning take-up device of (4) above, the winding guide part and the fixing part are integrated to form a cylindrical member, so that the robustness of the winding guide part and the fixing part can be ensured. Moreover, by moving the suction gun along the outer periphery of the cylindrical member while ensuring the robustness of the winding guide part and the fixing part, the suction gun can wind multiple yarns around the godet roller through the gap without contacting the godet roller.

[0021] (5) In the spinning take-up device of the present invention, It is preferable that the fixed portion and the winding guide portion are formed into a bottomless tubular member having an open end on the axial third region side with the godet roller fitted thereon.

[0022] According to the spinning take-up device of (5) above, since the fixing part and the winding guide part are bottomless tubular members whose ends on the axial third region side are open, it is possible to easily wind the yarn around the godet roller. That is, if the end on the axial third region side of the tubular member that fits the godet roller is closed, the airflow may be disturbed between the godet roller and the tubular member, i.e., radially outside the roller surface of the godet roller, making it difficult to wind the yarn around the godet roller. In this regard, by making the tubular member a tubular member whose end on the axial third region side is open, it is possible to suppress the disturbance of the airflow radially outside the roller surface of the godet roller, and it is possible to easily wind the yarn around the godet roller.

[0023] (6) In the spinning take-up device of the present invention, It is preferable that the gap has a first gap formed at a location where the multiple yarns are introduced to the godet roller, and a second gap formed downstream of the first gap in the yarn running direction of the multiple yarns and having an axial size smaller than that of the first gap.

[0024] According to the spinning take-up device described in (6) above, multiple yarns can be easily introduced from the first gap to the godet roller, while the second gap is smaller in the axial direction than the first gap, so that the suction gun can be prevented from coming into contact with the godet roller after the multiple yarns have been introduced.

[0025] (7) In the spinning take-up device of the present invention, The godet roller includes a first godet roller that sends the plurality of yarns spun from the spinning device downstream in the yarn running direction; A second godet roller is disposed downstream of the first godet roller in a yarn running direction and sends the yarns sent from the first godet roller downstream in the yarn running direction. the support member is a guide rail that supports the first godet roller and the second godet roller, At a winding position where the first godet roller and the second godet roller are close to each other, winding is performed in the order of the first godet roller and the second godet roller, When the plurality of yarns are wound, the second godet roller is moved along the support member to a winding position away from the first godet roller, The winding auxiliary member is At least one of the first godet roller and the second godet roller is provided. It is preferred.

[0026] According to the spinning take-up device described in (7) above, the winding assist member may be provided only to the first godet roller, only to the second godet roller, or both to the first godet roller and the second godet roller. In any case, the same effects as those of (1) to (6) above can be achieved.

[0027] The spinning take-up device according to the present invention does not necessarily have to include all of the configurations described in (1) to (7) above. For example, the spinning take-up device according to the present invention may be configured only with the configurations described in the spinning take-up device described in (1) above, or may be configured by arbitrarily combining the configuration described in (1) above with any of the configurations described in (2) to (7) above within a range in which consistency can be achieved. Effect of the Invention

[0028] According to the present invention, a yarn take-up device can be provided that facilitates winding, prevents damage to the godet roller, and improves safety. [Brief description of the drawings]

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] (Outline of spinning take-off device 1) Hereinafter, a preferred embodiment of the present invention (hereinafter, referred to as the present embodiment) will be described with reference to the drawings. Fig. 1 is a schematic diagram showing an example of a yarn take-up device 1 according to the present embodiment.

[0031] As shown in FIG. 1, the yarn take-up device 1 mainly includes a spinning device 2, an oil guide 4, a yarn drawing device 6, a first godet roller 10, a second godet roller 12, an intertwining device (not shown), and a yarn winding device 8.

[0032] In this specification, the up-down direction of the paper surface of Fig. 1 is the up-down direction, and the left-right direction of the paper surface of Fig. 1 is the front-rear direction. The direction perpendicular to the paper surface of Fig. 1 is the left-right direction, and the front side (near side) of the paper surface is the right side. The tip side of the bobbin holder 34 described later is the side where an operator operates the yarn take-up device 1, and this is the front side.

[0033] The spinning take-up device 1 is configured such that multiple yarns Y formed by solidifying molten fiber material such as polyester continuously spun from the spinning device 2 are stretched in the spinning stretching device 6, and then the yarns pass through a first godet roller 10 and a second godet roller 12 and are wound up by the yarn winding device 8.

[0034] The spinning device 2 continuously spins a molten fiber material such as polyester downward as a plurality of filaments F. The oil guide 4 combines the plurality of filaments F spun from the spinning device 2 into a single thread Y, and applies an oil to the thread Y (the plurality of filaments F). The plurality of threads Y to which the oil has been applied are sent to a spinning and drawing device 6.

[0035] The spinning and drawing device 6 is a device that heats and draws a plurality of yarns Y, and is disposed below the spinning device 2. The spinning and drawing device 6 has a heat-insulating box 14 and a plurality of heating rollers (not shown) housed inside the heat-insulating box 14.

[0036] The multiple yarns Y drawn by the spinning and drawing device 6 are taken up by a first godet roller 10 and further sent to the yarn winding device 8 by a second godet roller 12 provided downstream of the first godet roller 10 in the yarn running direction.

[0037] The first godet roller 10 is disposed below the spinning and drawing device 6 so that its axial direction is the left-right direction horizontally perpendicular to the spinning direction of the multiple yarns Y spun from the spinning device 2. The axial direction of the first godet roller 10 is also horizontally perpendicular to the longitudinal direction of a guide rail 26 described later. The second godet roller 12 is disposed downstream of the first godet roller 10 in the yarn running direction, at the rear upper part of the first godet roller 10, so that its axial direction is parallel to that of the first godet roller 10. The first godet roller 10 and the second godet roller 12 are supported by a roller lifting mechanism 20. The first godet roller 10 is rotated, for example, by a motor (not shown) as a driving source, but is not limited thereto, and may be a free roller that rotates without a motor.

[0038] The roller lifting mechanism 20 includes a bracket 22 that rotatably supports the first godet roller 10, a lifting bracket 24 that rotatably supports the second godet roller 12, a fixed frame (not shown), a guide rail 26, and a motor (not shown).

[0039] The guide rail 26 is a longitudinal member extending from one end to the other end. The guide rail 26 is disposed at an angle to the front-rear direction so that one end in the length direction (the front side in FIG. 1) is downward and the rear end (the rear side in FIG. 1) is upward. The guide rail 26 is supported by a fixed frame (not shown) extending in the horizontal direction. The above-mentioned "guide rail 26" corresponds to the "support member" of the present invention.

[0040] The bracket 22 rotatably supports the first godet roller 10 at one end of the guide rail 26 such that the rotation axis of the first godet roller 10 is perpendicular to the axial direction of a bobbin holder 34 described later. The lifting bracket 24 rotatably supports the second godet roller 12 such that the rotation axis of the second godet roller 12 is perpendicular to the axial direction of the bobbin holder 34. The lifting bracket 24 is movable along the length of the guide rail 26 by being driven by a motor (not shown). The second godet roller 12 moves along the length of the guide rail 26 as the lifting bracket 24 moves.

[0041] When the yarn Y is wound by the yarn winding device 8, the second godet roller 12 is located at a winding position indicated by a solid line in FIG. 1, i.e., at the other end of the guide rail 26, and is located approximately above the center in the axial direction of the bobbin holder 34. When the yarn Y is wound around the second godet roller 12, the second godet roller 12 is located at a winding position indicated by a broken line in FIG. 1, i.e., at one end of the guide rail 26, and is located close to the first godet roller 10. In this way, the second godet roller 12 can move between a winding position where it is close to the first godet roller 10 and a winding position where the distance from the first godet roller 10 is greater than that of the winding position. The second godet roller 12 is rotated, for example, by a motor (not shown) as a driving source, but is not limited thereto, and may be a free roller that rotates without a motor.

[0042] The intertwining device (not shown) is disposed between the first godet roller 10 and the second godet roller 12, and intertwines the filaments F that constitute one yarn Y to impart intertwining thereto.

[0043] The yarn winding device 8 is disposed below the first godet roller 10 and the second godet roller 12, and is configured to wind a plurality of yarns Y onto a plurality of bobbins B to form a package P. The yarn winding device 8 includes a plurality of swing support guides 31, a plurality of traverse guides 32, a turret 33, for example, two bobbin holders 34, a contact roller 35, and a yarn detection unit 36.

[0044] (Peripheral configuration of the first godet roller 10 and the second godet roller 12) Fig. 2 is an example of a schematic diagram of the periphery of the first godet roller 10 and the second godet roller 12 when the second godet roller 12 is disposed in the winding position, as viewed from the same direction as Fig. 1. Fig. 3 is an example of a perspective view of the periphery of the first godet roller 10 and the second godet roller 12 when the second godet roller 12 is disposed in the winding position, as viewed from the front right side.

[0045] 2 and 3, a cover member 50 is disposed radially outward of the first godet roller 10, and a cover member 70 is disposed radially outward of the second godet roller 12. Both the cover member 50 and the cover member 70 correspond to the "winding auxiliary member" of the present invention.

[0046] The cover member 50 ensures the safety of the operator when the yarn is wound around the first godet roller 10, and has a function of assisting in winding the yarn around the first godet roller 10 and preventing a suction gun (see FIGS. 7 and 8 described below) from contacting the first godet roller 10. The cover member 70, like the cover member 50, ensures the safety of the operator when the yarn is wound around the second godet roller 12, and has a function of assisting in winding the yarn around the second godet roller 12 and preventing a suction gun from contacting the second godet roller 12.

[0047] Hereinafter, in this specification, "winding the yarn" around the first godet roller 10 or the second godet roller 12 may be simply referred to as "winding".

[0048] (Cover member 50) The cover member 50 will be described in detail with reference to Figs. 4 to 6. Fig. 4 is a diagram for explaining the regions defined in this specification, and includes (A) an example of the first godet roller 10 as viewed from the front, (B) an example of the first godet roller 10 as viewed from the right, and (C) an example of the second godet roller 12 as viewed from the right. Fig. 5 is an example of a perspective view of the cover member 50 as viewed from above on the front right side. Fig. 6 shows (A) an example of a view of the cover member 50 as viewed from the front, and (B) an example of a view of the cover member 50 as viewed from the rear. The directions shown in Figs. 5 and 6 indicate the direction when the cover member 50 is disposed radially outward of the first godet roller 10.

[0049] First, referring to Fig. 4(A), the axial region (left-right direction shown in Fig. 4(A)) of the first godet roller 10 defined in this specification will be described. Region C shown in Fig. 4(A) is a region where multiple yarns Y are wound around the first godet roller 10 in the axial direction, and is referred to as the "first axial region C". Region L shown in Fig. 4(A) is a region closer to the base end (guide rail 26 side (left side)) than the first axial region, and is referred to as the "second axial region L". Region R shown in Fig. 4(A) is a region closer to the tip end (right side) than the first axial region, and is referred to as the "third axial region R".

[0050] Similarly, with regard to the second godet roller 12, the region where the multiple yarns Y are wound around the second godet roller 12 in the axial direction is referred to as the "first axial region C," the region closer to the base end (the guide rail 26 side (left side)) than the first axial region is referred to as the "second axial region L," and the region closer to the tip end (right side) than the first axial region is referred to as the "third axial region R."

[0051] With reference to FIG. 4(B), the circumferential regions of the first godet roller 10 defined in this specification will be described. E shown in FIG. 4(B) is a portion where the multiple yarns Y are introduced into the first godet roller 10 (hereinafter referred to as "introduction portion E"). F shown in FIG. 4(B) is a portion where the multiple yarns Y are led out from the first godet roller 10 (hereinafter referred to as "lead-out portion F"). Of the 360-degree circumferential direction, the region α shown in FIG. 4(B) is a region from the introduction portion E to the lead-out portion F facing the yarn running direction of the multiple yarns Y (counterclockwise in FIG. 4(B)), and is referred to as the "circumferential first region α". Of the 360-degree circumferential direction, the region β shown in FIG. 4(B) is a region from the introduction portion E to the lead-out portion F facing the opposite direction to the yarn running direction of the multiple yarns Y (clockwise in FIG. 4(B)), and is referred to as the "circumferential second region β". That is, the first circumferential region α is a region between the inlet section E and the outlet section F in the 360-degree circumferential direction of the first godet roller 10, where the multiple yarns Y are wound around the first godet roller 10. The second circumferential region β is a region between the inlet section E and the outlet section F in the 360-degree circumferential direction of the first godet roller 10, where the multiple yarns are not wound around the first godet roller 10. The inlet section E corresponds to the "inlet portion" of the present invention, and the outlet section F corresponds to the "outlet section" of the present invention.

[0052] As shown in FIG. 4C, the second godet roller 12 is also defined as having a "first circumferential region α" and a "second circumferential region β" in the same manner as the first godet roller 10. G shown in FIG. 4C is a region where the multiple yarns Y are introduced into the second godet roller 12 (hereinafter referred to as "introduction section G"). H shown in FIG. 4C is a region where the multiple yarns Y are led out from the second godet roller 12 (hereinafter referred to as "lead-out section H"). In addition, the region between the introduction section G and the lead-out section H in the 360-degree circumferential direction of the second godet roller 12, where the multiple yarns Y are wound around the second godet roller 12, is referred to as the "first circumferential region α." In addition, in the 360-degree circumferential direction of the second godet roller 12, a region between the inlet section G and the outlet section H, where multiple yarns are not wound around the second godet roller 12, is referred to as a "second circumferential region β." The inlet section G also corresponds to the "inlet portion" of the present invention, and the outlet section H also corresponds to the "outlet section" of the present invention.

[0053] As shown in FIG. 5, the cover member 50 in this embodiment is configured as a cylindrical member, and has a wrapping guide portion 52, a fixing portion 54, and a gap 60.

[0054] The winding guide portion 52 is a portion that allows winding of the material around the first godet roller 10 by simply bringing the tip of the suction gun into contact with the winding guide portion 52 and moving it along the winding guide portion 52 when using a suction gun (see Figs. 7 and 8 described later) to wind the material around the first godet roller 10. The winding guide portion 52 has a larger diameter than the roller diameter of the first godet roller 10 and is disposed radially outward of the first godet roller 10 so as to extrapolate the first godet roller 10.

[0055] In addition, it is sufficient that the wrapping guide portion 52 has at least a portion in the circumferential first region α (see Figure 4) in the circumferential direction, and is sufficient that it is disposed in at least the axial third region R (see Figure 4) in the axial direction.

[0056] The fixing portion 54 is a portion supported by the guide rail 26 (see FIG. 1) at the base end (left end) of the cover member 50. The fixing portion 54 has a function of fixing the winding guide portion 52 to the guide rail 26 and supporting the winding guide portion 52 on the guide rail 26. The axial direction of the cover member 50, which is made of a cylindrical member, is the same as the axial direction of the first godet roller 10. The winding guide portion 52 covers the entire width direction (left-right direction) of the roller surface of the first godet roller 10 when the fixing portion 54 is supported by the guide rail 26, i.e., when the fixing portion 54 is disposed radially outside the first godet roller 10. The winding guide portion 52 and the fixing portion 54 are preferably made of a rigid material, such as a metal.

[0057] In this embodiment, the cover member 50 is a bottomless cylindrical member, and the right end of the first godet roller 10 is open when the winding guide portion 52 is disposed on the radial outside of the first godet roller 10. If the other end (right end) of the first godet roller 10 in the axial direction is closed when the first godet roller 10 is inserted on the winding guide portion 52, the first godet roller 10 and the winding guide portion 52 may disturb the airflow on the radial outside of the first godet roller 10, making it difficult to wind the first godet roller 10. Therefore, by making the cover member 50 a bottomless cylindrical member, it is possible to suppress the disturbance of the airflow on the radial outside of the first godet roller 10, and it is possible to easily wind the first godet roller 10. However, it is not essential that the cover member 50 be a bottomless cylindrical member, and it is not intended to exclude the cover member 50 from being a bottomed cylindrical member.

[0058] The wrapping guide portion 52 of the cover member 50 includes a wrapping-side extending surface 53 that extends from the third axial region R toward the first axial region C (see FIG. 4 for both) radially outside the first godet roller 10. Including the wrapping-side extending surface 53 of the wrapping guide portion 52 can increase the strength of the wrapping guide portion 52, and can maintain stability when the tip of a suction gun (see FIGS. 7 and 8 described later) is pressed against the wrapping guide portion 52 to move the suction gun.

[0059] The winding-side extending surface 53 has a side surface 53a facing the guide rail 26 (leftward as shown in FIG. 5). A gap 60 is formed between this side surface 53a and a side surface 58a of a fixed-side extending surface 58 described below. The above-mentioned "winding-side extending surface 53" corresponds to the "other-side extending surface" of the present invention. Also, the above-mentioned "side surface 53a" corresponds to the "side portion" of the present invention.

[0060] The fixing portion 54 of the cover member 50 includes at least a connecting portion 55 that connects the guide rail 26 and the wrapping guide portion 52 , and a specific fixing portion 56 that is supported by the guide rail 26 .

[0061] The connecting portion 55 is disposed in the second circumferential region β. Therefore, the connecting portion 55 can be prevented from coming into contact with a plurality of threads Y.

[0062] The specific fixing portion 56 may be provided in the first circumferential region α without being provided in the second circumferential region β, may be provided in the second circumferential region β without being provided in the first circumferential region α, or may be provided in both the first circumferential region α and the second circumferential region β. In this embodiment, since the cover member 50 is a cylindrical member, the fixing portion 54 is provided in both the first circumferential region α and the second circumferential region β.

[0063] The fixed portion 54 includes a fixed-side extending surface 58 extending from the specific fixed portion 56 toward the first axial region (see FIG. 4) radially outward of the first godet roller 10. Since the fixed portion 54 includes the fixed-side extending surface 58, the fixed portion 54 can be stably fixed to the guide rail 26. The fixed-side extending surface 58 has a side surface 58a facing in the direction opposite to the guide rail 26 (to the right in FIG. 5). The above-mentioned "fixed-side extending surface 58" corresponds to the "one-side extending surface" of the present invention.

[0064] It is not essential that the wrapping guide portion 52 includes the wrapping-side extending surface 53 and the fixed portion 54 includes the fixed-side extending surface 58. For example, either of a mode in which the wrapping guide portion 52 includes the wrapping-side extending surface 53 and the fixed portion 54 does not include the fixed-side extending surface 58, or a mode in which the wrapping guide portion 52 does not include the wrapping-side extending surface 53 and the fixed portion 54 includes the fixed-side extending surface 58, may be used.

[0065] In addition, although it is preferable that the winding-side extending surface 53 and the fixed-side extending surface 58 are on the same plane, it is not essential that the winding-side extending surface 53 and the fixed-side extending surface 58 are on the same plane. For example, there may be a step between the winding-side extending surface 53 and the fixed-side extending surface 58.

[0066] The gap 60 is formed in the circumferential direction between the winding-side extending surface 53 and the fixed-side extending surface 58 in the axial direction of the first godet roller 10, i.e., on the side of the first axial region C from the winding guide portion 52. The gap 60 includes a first gap 62 formed in an introduction portion E (see FIG. 4) where the multiple yarns Y are introduced to the first godet roller 10, a second gap 64 formed in an outlet portion F (see FIG. 4) where the multiple yarns Y are outlet from the first godet roller 10, and a third gap 66 formed between the first gap 62 and the second gap 64 and downstream of the first gap 62 in the yarn running direction of the multiple yarns. The third gap 66 is formed continuously from the first gap 62, which is the introduction portion E, to the second gap 64, which is the outlet portion F, over at least the entire region of the first circumferential region α (see FIG. 4).

[0067] The first gap 62 is an opening through which the multiple yarns Y pass in order to wind the multiple yarns around the first godet roller 10, and is provided in an inverted triangular shape having an apex 63 below along the circumferential direction of the winding guide part 52. By making the first gap 62 in an inverted triangular shape in this way, the opening of the introduction part E of the multiple yarns to the first godet roller 10 can be made larger, and the yarns Y can be prevented from coming into contact with the cover member 50 when winding them around the first godet roller 10.

[0068] Moreover, the size (opening width) of the apex corner 63 below the first gap 62 in the axial direction (horizontal left-right direction) is smaller than that of the tip of the suction gun 80 (see Figs. 7 and 8 described later). Therefore, the tip of the suction gun 80 can be prevented from contacting the roller surface of the first godet roller 10.

[0069] The second gap 64 is an opening for leading out the multiple yarns from the first godet roller 10, and is provided in a rectangular shape along the circumferential direction. The opening width of the second gap 64 in the axial direction (horizontal left-right direction) is preferably larger than the opening width at the apex corner 63 of the first gap 62, and further larger than the yarn running width of the multiple yarns Y (the size in the direction perpendicular to the yarn running direction (i.e., the horizontal left-right direction)). In this way, when the yarn Y leaves the roller surface of the first godet roller 10, the separated yarn Y can be sent to the second godet roller 12 without coming into contact with the cover member 50.

[0070] The third gap 66 is an opening that is provided in a slit shape along the circumferential direction of the wrapping guide portion 52 so that the opening width is smaller than both the first gap 62 and the second gap 64 and the first gap 62 and the second gap 64 are connected. The opening width of the third gap 66 in the axial direction (horizontal left-right direction) is smaller than the tip of the suction gun 80 (see Figs. 7 and 8 described later). Therefore, even if the suction gun 80 is moved along the outer periphery of the wrapping guide portion 52, the tip of the suction gun 80 can be prevented from contacting the first godet roller 10.

[0071] It is preferable that the third gap 66 is provided so that the suction gun 80 can be wound around the first godet roller 10 simply by moving the suction gun 80 within the range of the third gap 66 provided in the circumferential direction of the winding guide portion 52. This makes it possible to more reliably prevent the tip of the suction gun 80 from coming into contact with the first godet roller 10 when winding the first godet roller 10.

[0072] (Wrapping on the first godet roller 10) Fig. 7 is a diagram showing the state when winding around the first godet roller 10 starts, and is an example of a diagram of the periphery of the first godet roller 10 as viewed from the front side. For convenience, Fig. 7 shows only the cover member 50, the first godet roller 10, and the suction gun 80, and does not show the guide rail 26, etc. Fig. 8 is a diagram showing the state during winding around the first godet roller 10, and is an example of a perspective view of the periphery of the first godet roller 10 and the second godet roller 12 as viewed from the front right side.

[0073] As shown in FIG. 7, the yarn Y is wound around the first godet roller 10 by moving the suction gun 80 from the axial third region R toward the winding guide portion 52 below the first gap 62. Then, as shown in FIG. 8, the suction gun 80 is moved counterclockwise along the circumferential direction while in contact with the outer periphery of the winding guide portion 52, so that the winding angle around the first godet roller 10 is less than 360 degrees. In this way, the suction gun 80 is moved along the circumferential direction while in contact with the outer periphery of the winding guide portion 52, so that a plurality of yarns Y can be wound around the first godet roller 10. In particular, it is preferable that the range in which the suction gun 80 is moved along the circumferential direction while in contact with the outer periphery of the winding guide portion 52 is approximately the range in which the third gap 66 is provided.

[0074] Furthermore, by adopting a cylindrical member in which the winding guide portion 52 and the fixing portion 54 are integrated as the cover member 50, it is possible to ensure the robustness of the cover member 50. Therefore, while moving the suction gun along the outer periphery of the cylindrical member, the yarns Y can be passed through the gaps 60 provided in the cylindrical member and wound around the first godet roller 10, so that the yarns can be easily wound around the first godet roller 10.

[0075] The wrapping guide portion 52 is preferably in the shape of a perfect circle when viewed from the right side as shown in FIG. 8. This is because the wrapping around the first godet roller 10, i.e., the suction gun 80 can be easily moved in the circumferential direction while being in contact with the outer periphery of the wrapping guide portion 52. However, the shape of the wrapping guide portion 52 when viewed from the right side is preferably in the shape of a perfect circle, but it is sufficient if it does not have any corners, and may be in the shape of an ellipse, for example. Furthermore, it is sufficient that the wrapping guide portion 52 is present at least in the first circumferential region α, and it is not necessary that it is present in the second circumferential region β.

[0076] (Cover member 70) The cover member 70 will be described in detail with reference to Fig. 9. Fig. 9 is an example of a perspective view of the cover member 70 as viewed from above on the front right side. Note that the direction shown in Fig. 9 indicates the direction when the cover member 70 is disposed radially outside the second godet roller 12.

[0077] The cover member 70 has a wrapping guide portion 72 and a fixed portion 74. The wrapping guide portion 72 has a side surface 72a facing the guide rail 26 (to the left as shown in FIG. 9), and the fixed portion 74 has a side surface 74a facing the opposite side to the guide rail 26 (to the right as shown in FIG. 9). A gap 76 is formed between the side surface 72a of the wrapping guide portion 72 and the side surface 74a of the fixed portion 74. The above-mentioned "side surface 72a" also corresponds to the "side portion" of the present invention.

[0078] The winding guide portion 72 is a portion that allows winding of the material around the second godet roller 12 by simply bringing the tip of the suction gun into contact with the winding guide portion 72 and moving it along the winding guide portion 72 when using a suction gun (see Figs. 7 and 8 described later) to wind the material around the second godet roller 12. The winding guide portion 72 has a larger diameter than the roller diameter of the second godet roller 12 and is disposed radially outward of the second godet roller 10 at least in a third axial region R.

[0079] In addition, it is sufficient that the wrapping guide portion 72 has at least a portion in the circumferential first region α (see Figure 4) in the circumferential direction, and is sufficient that it is disposed in at least the axial third region R (see Figure 4) in the axial direction.

[0080] The fixing portion 74 is a portion supported by the guide rail 26 (see FIG. 1) at the base end (left end) of the cover member 70. This fixing portion 74 has a function of fixing the winding guide portion 72 to the guide rail 26 and supporting the winding guide portion 72 on the guide rail 26. The axial direction of the cover member 70 is the same as the axial direction of the second godet roller 12. When the fixing portion 74 is supported by the guide rail 26, i.e., when the fixing portion 74 is disposed radially outside the second godet roller 12, the winding guide portion 72 covers the entire width direction (left-right direction) of the roller surface of the second godet roller 12. The winding guide portion 72 and the fixing portion 74 are preferably made of a rigid material, for example, a metal.

[0081] The gap 76 is formed between the winding guide portion 72 and the fixed portion 74, i.e., on the axial first region C side of the winding guide portion 72, along the circumferential direction. The opening width of the gap 76 is preferably larger than the yarn running width of the multiple yarns Y. In this manner, the yarn Y sent to the second godet roller 12 can be brought into contact with the roller surface of the second godet roller 12 without coming into contact with the cover member 70. The gap 76 is formed continuously from the introduction portion G to the discharge portion H, over at least the entire circumferential first region α (see FIG. 4).

[0082] In addition, since the second godet roller 12 is farther from the operator than the first godet roller 10, winding the yarn around the second godet roller 12 is more difficult than winding the yarn around the first godet roller 10. However, by making the opening width of the gap 76 larger than the yarn running width of the multiple yarns Y, it is possible to easily wind the multiple yarns around the second godet roller 12.

[0083] Furthermore, the wrapping around the second godet roller 12 is performed from the lower right side of the second godet roller 12, but since the wrapping guide portion 72 is provided on the right end side of the axial direction (horizontal left-right direction) of the second godet roller 12, the suction gun 80 can be prevented from contacting the roller surface of the second godet roller 12.

[0084] (Wrapping on the second godet roller 12) 10 is a diagram showing the state when winding around the second godet roller 12 starts, and is an example of a perspective view of the periphery of the first godet roller 10 and the second godet roller 12 as seen from the front right side. As described above, when winding around the second godet roller 12, the second godet roller 12 is located at the winding position (the position indicated by the dashed line in FIG. 1).

[0085] As shown in FIG. 10, the yarns are wound around the second godet roller 12 by moving the suction gun 80 from the axial third region R toward the winding guide portion 72 below the gap 76. The suction gun 80 is then moved clockwise along the circumferential direction while in contact with the outer periphery of the winding guide portion 72, so that the winding angle around the second godet roller 12 is less than 360 degrees. In this way, the suction gun 80 is moved along the circumferential direction while in contact with the outer periphery of the winding guide portion 72, so that the yarns Y pass through the gap 76 and come into contact with the roller surface of the second godet roller 12, and are wound around the second godet roller 12. When the yarns are wound around the second godet roller 12, the second godet roller 12 moves along the length of the guide rail 26 toward the winding position (the position indicated by the solid line in FIG. 1).

[0086] It is preferable that the shape of the wrapping guide portion 72 is a perfect circular arc when viewed from the right side as shown in FIG. 10. This is because the wrapping around the second godet roller 12, i.e., the suction gun 80 can be easily moved in the circumferential direction while being in contact with the outer periphery of the wrapping guide portion 72. However, the shape of the wrapping guide portion 72 when viewed from the right side is preferably a perfect circular arc, but it is sufficient if it does not have any corners, and may be, for example, an elliptical arc. It is sufficient that the wrapping guide portion 72 is present at least in the first circumferential region α, and it is not necessary that it is present in the second circumferential region β.

[0087] (Action and effect) According to the spinning take-up device 1 of the present embodiment, the cover member 50 is provided on the radially outer side of the first godet roller 10, so that the operator can be prevented from contacting the first godet roller 10, and the winding of the yarn around the first godet roller 10 can be assisted, thereby improving safety during winding. In particular, when the first godet roller 10 is rotating, it is dangerous for the operator, but by providing the cover member 50 on the radially outer side of the first godet roller 10, the safety of the operator can be ensured. Moreover, by pressing the tip of the suction gun 80 against the winding guide portion 52 from the side of the third axial region R, and then moving the suction gun 80 along the winding guide portion 52, it is possible to wind a plurality of yarns around the first godet roller 10 so that the suction gun 80 does not come into contact with the first godet roller 10. Therefore, winding around the first godet roller 10 can be performed with a simple operation, and further, damage to the first godet roller 10 can be prevented.

[0088] In addition, since the cover member 70 is provided on the radial outside of the second godet roller 12, it is possible to prevent the operator from coming into contact with the second godet roller 12, and it is possible to assist in winding the yarn around the second godet roller 12 and improve safety during winding. In particular, when the second godet roller 12 is rotating, it is dangerous for the operator, but by providing the cover member 70 on the radial outside of the second godet roller 12, it is possible to ensure the safety of the operator. Moreover, by pressing the tip of the suction gun 80 against the winding guide portion 72 from the side of the third axial region R, and then moving the suction gun 80 along the winding guide portion 72, it is possible to wind multiple yarns around the second godet roller 12 so that the suction gun 80 does not come into contact with the second godet roller 12. Therefore, it is possible to wind the yarn around the second godet roller 12 with a simple operation, and further, it is possible to prevent the second godet roller 12 from being damaged.

[0089] In addition, the cover member 50 is composed of a bottomless cylindrical member whose right end in the axial direction (horizontal left-right direction) is open when the first godet roller 10 is inserted therearound, thereby suppressing airflow turbulence radially outside the first godet roller 10 and making it easy to wrap the cover member 50 around the first godet roller 10.

[0090] The cover member 50 has a first gap 62 having an inverted triangular shape with an apex corner 63 at a lower side at an introduction section E where the yarns Y are introduced to the first godet roller 10. The opening width of the apex corner 63 is smaller than the tip of the suction gun 80. Similarly, the opening width of the third gap 66 is smaller than the tip of the suction gun 80. This prevents the tip of the suction gun 80 from coming into contact with the roller surface of the first godet roller 10 when the yarns Y are wound around the first godet roller 10.

[0091] The cover member 50 also has a rectangular second gap 64 at the lead-out section F where the multiple yarns Y are led out from the first godet roller 10. The opening width of the second gap 64 is larger than the opening width at the lower apex corner 63 of the first gap 62, so that when the yarns Y leave the roller surface of the first godet roller 10, the separated yarns Y can be prevented from coming into contact with the cover member 50.

[0092] Furthermore, the cover member 50 has a slit-like third gap 66 between the first gap 62 and the second gap 64, the opening width of which is smaller than the tip of the suction gun. This makes it possible to wrap the first godet roller 10 with a simple operation while ensuring the safety of the operator over the entire range from the start to the end of wrapping the first godet roller 10, and prevents the first godet roller 10 from being scratched due to contact with the suction gun 80.

[0093] (Modification) Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these examples, and various modifications are possible within the scope of the claims. For example, in the above-mentioned embodiment, the cover member 50 is provided on the radial outside of the first godet roller 10, and the cover member 70 is provided on the radial outside of the second godet roller 12, but the present invention is not limited to this. In other words, a cover member (cover member 50 or cover member 70) may be provided on the radial outside of at least one of the first godet roller 10 and the second godet roller 12.

[0094] Even if the cover member 50 is replaced with the cover member 50A, the cover member 50A can have a function of assisting in winding the yarn around the first godet roller 10. Similarly, even if the cover member 70 is replaced with the cover member 70A, the cover member 70A can have a function of assisting in winding the yarn around the second godet roller 12. In other words, both the cover member 50A and the cover member 70A can be said to correspond to the "winding assist member" of the present invention.

[0095] In the above-described embodiment, the cover member 50 is a cylindrical member, but as long as the first godet roller 10 can be wrapped around it with a simple operation while ensuring the safety of the operator, the cover member 50 does not necessarily have to be a cylindrical member. For example, the cover member 50 may be configured with a ring-shaped winding guide portion and a fixing portion that fixes the ring-shaped winding guide portion to the guide rail 26, instead of a cylindrical member. The same applies to the cover member 70. Below, a modified example in which the cover member 50, which is a cylindrical member, is changed to a cover member 50A having a ring-shaped winding guide portion 52A and a connecting fixing portion 54A, and the cover member 70, which is a cylindrical member, is changed to a cover member 70A having a ring-shaped winding guide portion 72A and a fixing portion 74A will be described with reference to FIG. 11.

[0096] Fig. 11 is a modified example showing a perspective view of the periphery of the first godet roller 10 and the second godet roller 12 when the second godet roller 12 is disposed in the winding position. In Fig. 11, a cover member 50A is provided instead of the cover member 50, and a cover member 70A is provided instead of the cover member 70.

[0097] The cover member 50A has a ring-shaped winding guide portion 52A having a diameter larger than the roller diameter of the first godet roller 10, and a connecting and fixing portion 54A.

[0098] The wrapping guide portion 52A has a side surface 52Aa facing the guide rail 26 (leftward as shown in FIG. 9), and a space 60A is formed between the side surface 52Aa and the guide rail 26. The space 60A is formed in the first axial region C from the wrapping guide portion 52A. The above-mentioned "side surface 52Aa" also corresponds to the "side portion" of the present invention.

[0099] The connecting and fixing part 54A is a rod-shaped member extending leftward from the winding guide part 52A, and its left end is supported by the guide rail 26. The connecting and fixing part 54A has a function of connecting the winding guide part 52A and the guide rail 26, and a function of being supported by the guide rail 26. The connecting and fixing part 54A is disposed in the axial direction in the second circumferential region β (see FIG. 4(B)). This makes it possible to prevent the connecting and fixing part 54A from coming into contact with multiple yarns Y.

[0100] Even when the cover member 50A is configured as shown in FIG. 11, by moving the suction gun along the winding guide portion 52A, multiple yarns can be wound around the first godet roller 10 from the space portion 60A without the suction gun coming into contact with the first godet roller 10.

[0101] The cover member 50A has the connecting and fixing portion 54A having both the function of connecting the winding guide portion 52A and the guide rail 26 and the function of being supported by the guide rail 26. Alternatively, the cover member 50A may have a connecting portion having the function of connecting the winding guide portion 52A and the guide rail 26 and a specific fixing portion having the function of being supported by the guide rail 26. In this case, the connecting portion can be prevented from coming into contact with the multiple yarns Y as long as it is disposed in the circumferential second region β at least in the axial first region C. That is, the connecting portion may be disposed in the circumferential first region α (see FIG. 4 for both) in the axial second region L and the axial third region R. The specific fixing portion may be disposed in either the circumferential first region α or the circumferential second region β.

[0102] Similarly, the cover member 70A has a ring-shaped winding guide portion 72A having a diameter larger than the roller diameter of the second godet roller 12, and a connecting and fixing portion 74A.

[0103] The wrapping guide portion 72A has a side surface 72Aa facing the guide rail 26 (to the left in FIG. 9), and a space portion 76A is formed between the side surface 72Aa and the guide rail 26. The space portion 76A is formed in the first axial region C from the wrapping guide portion 72A. The above-mentioned "side surface 72Aa" also corresponds to the "side portion" of the present invention.

[0104] The connecting and fixing part 74A is a rod-shaped member extending leftward from the winding guide part 72A, and is supported at its left end by the guide rail 26. The connecting and fixing part 74A has a function of connecting the winding guide part 72A and the guide rail 26, and a function of being supported by the guide rail 26. The connecting and fixing part 74A is disposed in the axial direction in the second circumferential region β (see FIG. 4(C)). This makes it possible to prevent the connecting and fixing part 54A from coming into contact with multiple yarns Y.

[0105] Even when the cover member 70A is configured as shown in FIG. 11, by moving the suction gun along the winding guide portion 72A, multiple yarns can be wound around the second godet roller 12 from the space portion 76A without the suction gun coming into contact with the second godet roller 12.

[0106] The cover member 70A also has a connecting and fixing part 74A having both a function of connecting the winding guide part 72A and the guide rail 26 and a function of being supported by the guide rail 26, as in the cover member 50A. Alternatively, the cover member 70A may have a connecting part having a function of connecting the winding guide part 72A and the guide rail 26 and a specific fixing part having a function of being supported by the guide rail 26. In this case, if the connecting part is disposed in the circumferential second region β at least in the axial first region C, it is possible to prevent the connecting part from coming into contact with the multiple yarns Y. That is, the connecting part may be disposed in the circumferential first region α (see FIG. 4 for both) in the axial second region L and the axial third region R. Moreover, the specific fixing part may be disposed in either the circumferential first region α or the circumferential second region β.

[0107] In this way, even if the cover member 50A is provided instead of the cover member 50 on the radial outside of the first godet roller 10, it is possible to prevent the operator from coming into contact with the first godet roller 10, assist in winding the yarn around the first godet roller 10, and improve safety during winding, as in the case where the cover member 50 is provided. In addition, winding around the first godet roller 10 can be performed by a simple operation of moving the suction gun 80 in the circumferential direction while abutting against the outer periphery of the winding guide portion 52A, and damage to the first godet roller 10 can also be prevented.

[0108] Similarly, even if a cover member 70A is provided on the radially outer side of the second godet roller 12 instead of the cover member 70, it is possible to prevent the operator from contacting the second godet roller 12, assist in winding the yarn around the second godet roller 12, and improve safety during winding, as in the case where the cover member 70 is provided. In addition, winding the yarn around the second godet roller 12 can be performed by a simple operation of moving the suction gun 80 in the circumferential direction while abutting against the outer periphery of the winding guide portion 72A, and damage to the second godet roller 12 can also be prevented.

[0109] The cover member 50A has a ring-shaped winding guide portion 52A. That is, the cover member 50A has the winding guide portion 52A in the entire circumferential region, but is not limited to this. The winding guide portion may be, for example, a ring-shaped portion with a part cut out. If at least a portion of the first circumferential region α of the winding guide portion is provided in the third axial region R (see FIG. 4), the multiple yarns can be wound around the godet roller so that the suction gun 80 (see FIG. 7 and FIG. 8) does not come into contact with the godet roller.

[0110] Similarly, the cover member 70A has a ring-shaped winding guide portion 72A. That is, the cover member 70A has the winding guide portion 72A in the entire circumferential region, but is not limited to this. The winding guide portion may be, for example, a ring-shaped portion with a part cut out. If at least a portion of the winding guide portion in the circumferential direction, which is the first circumferential region α, is provided in the third axial region R (see FIG. 4), the multiple yarns can be wound around the godet roller so that the suction gun 80 (see FIG. 7 and FIG. 8) does not come into contact with the godet roller.

[0111] That is, each of the wrapping guide portions 52A and 72A may be in a range necessary for wrapping the yarn Y around the godet rollers 10, 12 using at least the suction gun 80 (see Figs. 7 and 8).

[0112] Moreover, both the wrapping guide portion 52A and the wrapping guide portion 72A preferably have a shape of a perfect circle when viewed from the right direction shown in Fig. 11, similar to the wrapping guide portion 52 and the wrapping guide portion 72. However, this is not limited thereto, and the wrapping guide portion 52A and the wrapping guide portion 72A may have, for example, an elliptical arc shape as long as they do not have any corners when viewed from the right direction shown in Fig. 11.

[0113] 11, both the cover member 50 and the cover member 70 are changed to the cover member 50A and the cover member 70A, respectively. However, this is not limited thereto, and only one of the cover member 50 and the cover member 70 may be changed to the cover member 50A or the cover member 70A.
