Description

Technical Field

[0001] The present invention relates to a spinning and drawing device for drawing a silk thread spun from a spinning machine to form a wound package, and particularly relates to a spinning and drawing device for silk threads for industrial materials having a relatively large fineness and requiring a relatively long heating length. Background Art

[0002] In a spinning and drawing device for drawing a silk thread spun from a spinning machine to form a wound package, at the start of production, a threading operation of hooking the silk thread spun from the spinning machine along a silk thread passage to a winding part is required.

[0003] In a general spinning and drawing device, as disclosed in Patent Document 1 (particularly referring to Fig. 1), a processing component including a plurality of rollers etc. is arranged below the spinning machine, and the winding part is arranged below the processing component. When performing the threading operation in such a spinning and drawing device, as an operator on one floor, there are threading workers (workers on the mezzanine (a floor between the first floor and the second floor)) who thread the silk thread to each roller etc., and threading workers who thread the silk thread to the winding part arranged below each roller etc.

[0004] Patent Document 1: U.S. Patent Application Publication No. 2009 / 0049669

[0005] However, in recent years, labor saving of equipment has been required. However, when performing the threading operation in the conventional spinning and drawing device described in Patent Document 1, at least two operators are required, namely, mezzanine workers who thread the silk thread to each roller etc. and threading workers who thread the silk thread to the winding part. In addition, when the threading operation is performed by these two operators, namely, mezzanine workers who thread the silk thread to each roller etc. and threading workers who thread the silk thread to the winding part, when threading the silk thread to each roller and the winding part, the transfer of a suction gun that sucks the silk thread is required, so the threading operation time increases. Assuming that even if one operator performs the threading to each roller and the winding part, since the threading operation at the mezzanine where each roller is arranged becomes a high-altitude operation, it is necessary to ride on a working platform for ascending and descending, not only does the time required for threading become longer, but the operation burden on the operator also increases. Therefore, it has become an urgent issue to reduce the height of the spinning and drawing device to achieve a low height, shorten the threading time, and save labor. Summary of the Invention

[0006] The present invention has been made in view of the above problems, and its object is to make the spinning and drawing device lower in height (Japanese: lower floor) compared with the prior art, and to shorten the threading time and save labor.

[0007] (1) The spinning and drawing device of the present invention is

[0008] The spinning drawing device is characterized by comprising a spinning drawing section for drawing and at least stretching multiple filaments spun from a spinning machine, and a take-up section for winding the multiple filaments fed from the spinning drawing section into a take-up package.

[0009] The above-mentioned spinning drawing section includes:

[0010] The first guide section guides the multiple filaments spun from the spinning machine to the downstream side in the direction of filament travel.

[0011] The stretching section includes a plurality of rollers, at least one of which is used to stretch the plurality of filaments guided from the first guide section; and

[0012] The second guide section guides the plurality of filaments from the stretching section to the winding section.

[0013] The aforementioned winding section and stretching section are arranged horizontally.

[0014] The second guide section has a guide roller disposed downstream of the yarn travel direction of the stretching section, and a plurality of distribution rollers disposed at a position downstream of the guide roller in the yarn travel direction and having a drive section disposed above the winding section. The plurality of yarns from the stretching section are fed to the winding section via the guide roller and the plurality of distribution rollers.

[0015] According to the spinning traction device described in (1) above, multiple filaments from the stretching section are fed to the winding section via guide rollers and distribution rollers. Therefore, by horizontally arranging the winding section and the stretching section, the height of the spinning traction device can be reduced, thus achieving a lower height. As a result, it is not necessary to separate the working area of ​​one layer vertically and assign operators to each working area separately as in the past, and one operator can perform the filament hanging operation. Therefore, the filament hanging operation time can be shortened, and labor saving can be achieved.

[0016] (2) In the spinning traction device described in (1) above, the characteristic is that,

[0017] The aforementioned multiple distribution rollers are configured such that the acute angle formed between the direction of the filament travel from the aforementioned guide rollers and the horizontal plane is greater than 0 degrees and less than 20 degrees.

[0018] According to the spinning traction device described in (2) above, the height of the guide roller can be suppressed, and the height of the spinning traction device can be reduced. That is, the lower limit of the height direction of the distribution roller is determined by other components such as the take-up section. Therefore, by arranging the guide roller and the distribution roller such that the acute angle formed by the direction of the yarn travel from the guide roller to each distribution roller and the horizontal plane is 0 degrees or more and 20 degrees or less, the guide roller and the distribution roller can be lowered, thereby reducing the height of the spinning traction device.

[0019] (3) In the spinning traction device described in (1) or (2) above, the characteristic is that,

[0020] The aforementioned distribution rollers are arranged in a straight line along the yarn path from the aforementioned guide rollers to their respective distribution rollers in a top view.

[0021] The thread channels from the guide rollers to the distribution rollers are such that, corresponding to the distribution rollers, multiple thread channels are formed that are separated in a direction orthogonal to the thread channels in a top view.

[0022] The aforementioned multiple distribution rollers are configured to avoid the thread channels corresponding to other distribution rollers.

[0023] According to the spinning traction device described in (3) above, the multiple distribution rollers are configured to avoid the yarn channels corresponding to other distribution rollers. As a result, the yarn delivered from the guide roller does not come into contact with the roller surfaces of other distribution rollers.

[0024] (4) In the spinning traction device described in (3) above, the characteristic is that,

[0025] The aforementioned multiple distribution rollers have different roller surface heights depending on their positions relative to the direction orthogonal to both the yarn path from the guide roller to the distribution roller and the vertical direction.

[0026] According to the spinning traction device described in (4) above, the height of the roller surface varies depending on the position of the direction orthogonal to both the yarn path from the guide roller to the distribution roller and the vertical direction, thus ensuring the yarn path for each yarn being fed to the multiple distribution rollers. As a result, the yarn fed from the guide roller does not come into contact with the roller surfaces of other distribution rollers.

[0027] (5) In the spinning traction device described in (3) or (4) above, the characteristic is that,

[0028] At least one of the aforementioned distribution rollers has its axial direction inclined relative to the horizontal direction.

[0029] According to the spinning traction device described in (5) above, by simply making the axial direction of the distribution roller tilted relative to the horizontal direction, it is possible to prevent the yarn fed from the guide roller from contacting the roller surface of other distribution rollers.

[0030] (6) In any of the spinning drawing devices described in (3) to (5) above, the characteristic is that,

[0031] At least one of the aforementioned distribution rollers is a conical or stepped roller with a different diameter depending on its position relative to both the direction orthogonal to the direction of the wire channel from the guide roller to the distribution roller and the vertical direction.

[0032] According to the spinning traction device described in (6) above, by simply changing the distribution roller to a conical or stepped roller with a different diameter depending on the position of the direction orthogonal to both the yarn channel and the vertical direction, it is possible to prevent the yarn fed from the guide roller from contacting the roller surface of other distribution rollers.

[0033] (7) In the spinning traction device described in (3) above, the characteristic is that,

[0034] The aforementioned distribution rollers are configured such that the roller surface of the distribution roller closest to the guide roller has the lowest height position, and the roller surface of the distribution roller increases as it moves away from the guide roller.

[0035] According to the spinning traction device described in (7) above, the height position of the distribution roller surface closest to the guide roller is the lowest, and the height position of the distribution roller surface increases as it moves away from the guide roller. Therefore, by simply staggering the installation height positions of multiple distribution rollers, it is possible to prevent the yarn fed from the guide roller from contacting the roller surfaces of other distribution rollers.

[0036] (8) In any of the spinning drawing devices described in (1) to (7) above, the characteristic is that,

[0037] It further includes multiple drive units corresponding to the aforementioned multiple distribution rollers.

[0038] According to the spinning traction device described in (8) above, multiple distribution rollers can be driven independently, thereby reducing the tension difference between multiple filaments downstream of the multiple distribution rollers. As a result, the quality of the winding and packaging can be stabilized.

[0039] The effects of the invention

[0040] According to the present invention, the height of the spinning traction device is reduced to a lower height compared to the past, which can shorten the yarn hanging time and save manpower. Attached Figure Description

[0059] Hereinafter, the spinning traction device 1 of the present invention will be described with reference to the accompanying drawings. The spinning traction device 1 of the present invention is a device for drawing industrial material yarns, for example, with a denier of 300 or higher. Figure 1 This is an example of a schematic perspective view of the spinning traction device 1. Figure 2 This is an example of a schematic side view showing the spinning traction device 1.

[0060] Furthermore, in this embodiment, such as Figure 1 as well as Figure 2 The X and Y directions are defined as shown. Both the X and Y directions are horizontal and orthogonal to each other. The X direction is... Figure 1 as well as Figure 2 The direction indicated by the arrow. Therefore, in the case of "the opposite direction of the X direction" referred to in this specification, it means... Figure 1 as well as Figure 2 The arrows shown are in the opposite direction. On the other hand, the Y direction is... Figure 1 as well as Figure 2 The two directions indicated by the arrows.

[0061] [1. Overall Structure of the Spinning Traction Device]

[0062] Reference Figure 1 as well as Figure 2 A general description of the overall structure of the spinning traction device 1 is provided. For example... Figure 1 as well as Figure 2 As shown, the spinning traction device 1 mainly comprises an oil supply unit 2, a yarn attraction unit 4, a spinning traction unit 6, and a winding unit 8, starting from the upstream side of the yarn travel direction.

[0063] The oil supply unit 2 has multiple oil supply units 2. These multiple oil supply units 2 are configured to... Figure 2 Arranged in a column along the left-right direction on the paper. Here, the phrase "arranged in a column along the X direction" is used instead of "arranged in a column". Figure 2 The reason for "arranging them in a single column along the left and right sides on the paper" will be referred to Figure 4 To be discussed later.

[0064] In addition, although Figure 1 as well as Figure 2 Although not shown in the figure, a spinning machine is arranged above multiple oil supply units 2. The multiple oil supply units 2 apply oil to the bundles of yarn 100 spun from the spinning machine to form filaments. In this embodiment, the spinning traction device 1 includes oil supply units 2, but it is not limited to this, and the spinning machine may also include oil supply units 2.

[0065] The yarn attraction section 4 has multiple yarn attraction sections 4, which are generally referred to as vacuum generators. When the spinning traction device 1 is equipped with an oil supply section 2, these multiple yarn attraction sections 4 are respectively arranged directly below the corresponding oil supply section 2, and temporarily attract and hold the yarn 100 when it is wound onto each roller or when a yarn breaks. The yarn 100, coated with oil by the oil supply section 2, passes directly downward in front of the yarn attraction section 4 and travels toward the first guide section 10 described later. The multiple yarn attraction sections 4 are mainly configured to generate an attraction force at the attraction port by the flow of compressed fluid.

[0066] The spinning traction unit 6, starting from the upstream side in the direction of yarn travel, mainly comprises a first guide unit 10, a first yarn conveying roller 20, a stretching unit 28, a buffering unit 60, and a distribution unit 70. Details regarding the first guide unit 10, the first yarn conveying roller 20, the stretching unit 28, the buffering unit 60, and the distribution unit 70 will be described later.

[0067] The take-up unit 8 mainly includes a main frame 80, a first take-up device 81, and a second take-up device 91. The first take-up device 81 and the second take-up device 91 are arranged along the Y direction. The first take-up device 81 and the second take-up device 91 have the same structure, so the first take-up device 81 will be described below, and the description of the second take-up device 91 will be omitted. In this embodiment, the take-up unit 8 includes two units, the first take-up device 81 and the second take-up device 91, but it is not limited to this and may also include one take-up device.

[0068] The first winding device 81 mainly includes: a circular plate-shaped turntable 82 that is rotatably mounted on the main frame 80; two winding shafts 84 that are cantilevered on the turntable 82 and take the X direction as the axis; and multiple traversing devices 85 for traversing the yarn 100.

[0069] A plurality of bobbins 86 are mounted in a straight line on a take-up shaft 84. The take-up shaft 84 is rotated by a motor (not shown), thereby rotating the plurality of bobbins 86 mounted on the take-up shaft 84, and winding yarn 100 onto the rotating plurality of bobbins 86. The yarn 100 wound onto the bobbins 86 forms a take-up package.

[0070] Here, we will continue to refer to Figure 1 as well as Figure 2 The positional relationship between the stretching section 28 and the winding section 8 of the spinning traction unit 6 will be explained. The stretching section 28 is positioned upstream of the winding section 8 in the direction of yarn travel and opposite to the winding section 8 in the X direction. Specifically, the stretching section 28 and the winding section 8 are arranged horizontally on the same floor, such that the axial direction of the winding shaft 84 is parallel to the direction of yarn travel of the yarn 100 in the stretching section 28 when viewed from above. That is, in this embodiment, the stretching section 28 is arranged at almost the same height as the winding section 8, which is different from conventional spinning traction devices that separate the working areas of the first floor vertically, arranging the winding section in the lower working area of ​​the first floor and the stretching section in the upper working area. As a result, the stretching section 28 can be configured such that a single operator can perform the yarn-hanging operation of the stretching section and the winding section without using a work trolley or the like. As a result, the yarn-hanging operation time can be shortened, and labor saving can be achieved.

[0071] Furthermore, a first guide section 10 is disposed near the upper part of the stretching section 28. Additionally, a yarn suction section 4 is disposed directly above the first guide section 10, and an oil supply section 2 is disposed directly above the yarn suction section 4. The effects of arranging these components in such a proximity will be described later, including their positional relationship with the first yarn conveying roller 20.

[0072] [2. Spinning drawing section]

[0073] The first guide section 10, the first yarn conveying roller 20, the stretching section 28, the easing section 60, and the distribution section 70 of the spinning traction section 6 will be described below.

[0074] [2-1. First guide section, first wire conveyor roller]

[0075] Figure 3 This is an example of a side view showing the periphery of the first guide section 10. For example... Figure 3 As shown, the first guide section 10 is mainly composed of a plurality of (e.g., 12) direction-changing rollers 10A to 10L. The plurality of direction-changing rollers 10A to 10L are arranged in a manner that... Figure 3 The paper is arranged in a row along the left-right direction. Specifically, the direction-changing rollers 10A to 10F... Figure 3 The direction-changing rollers 10G to 10L are arranged from left to right on the paper surface. Figure 3 The arrangement on the paper is from right to left. Here, it is noted that it is not written as "arranged in a column along the X direction" but rather as "in..." Figure 3 The reason given for "arranging them in a column along the left and right direction on the paper" is the same as the record stating "in..." Figure 2 The multiple oil supply units 2, arranged in a row along the left and right direction on the paper, will be referenced. Figure 4 To be discussed later.

[0076] Furthermore, in this embodiment, it is described that multiple direction-changing rollers 10A to 10L are configured to... Figure 3 The main elements are arranged in a row along the left and right direction on the paper surface, but multiple direction changing rollers 10A to 10L can also be arranged horizontally or staggered in the up and down direction.

[0077] The multiple direction-changing rollers 10A to 10L are rollers used to convey multiple (e.g., 12) filaments 100, spun downwards from the spinning machine and coated with an oil, to a first filament conveying roller 20, which is positioned slightly lower than the horizontal direction for each of the multiple filaments 100. Furthermore, "slightly lower than the horizontal direction" is preferably slightly lower than the horizontal direction. For example, the acute angle formed by the direction of the filaments 100 conveyed from the direction-changing rollers 10A to 10L to the first filament conveying roller 20 and the horizontal plane is preferably greater than 5 degrees and less than 30 degrees. "The acute angle formed by the direction of the filaments 100 conveyed from the direction-changing rollers 10A to 10L to the first filament conveying roller 20 and the horizontal plane" is equivalent to... Figure 3 The angle α shown.

[0078] The yarn 100, whose direction of travel has been changed by the direction-changing rollers 10A to 10F, is wound onto the first take-up device 81 (see reference). Figure 1The yarn 100, whose direction of travel has been changed by the direction-changing rollers 10G to 10L, is fed to the second take-up device 91 (see reference). Figure 1 Convey and wind up.

[0079] The first thread conveying roller 20 is a roller disposed on the thread channel from the first guide section 10 to the stretching section 28, and is a roller with its axial direction being approximately orthogonal to both the thread travel direction and the vertical direction (i.e., the Y direction). The first thread conveying roller 20 is disposed vertically between the first guide section 10 (i.e., the plurality of direction-changing rollers 10A to 10L) and the stretching section 28, and horizontally disposed at a position opposite to the X direction of both the first guide section 10 (more specifically, the direction-changing roller 10G) and the stretching section 28. That is, the first guide section 10 and the stretching section 28 are disposed vertically in a position where they overlap when viewed from above, while the first thread conveying roller 20 is disposed at a position that does not overlap with either the first guide section 10 or the stretching section 28 when viewed from above, and is offset horizontally. However, from the viewpoint of saving space, the first thread conveying roller 20 is preferably located near the first guide section 10 and the stretching section 28 in the horizontal direction.

[0080] Thus, by arranging the first guide section 10 near the upper part of the stretching section 28, and arranging the first yarn conveying roller 20 at a position offset from both the first guide section 10 and the stretching section 28 in the opposite direction of the X direction, the vertical distance between the first guide section 10 and the stretching section 28 can be reduced. Furthermore, by reducing the vertical distance between the first guide section 10 and the stretching section 28, the height of the first guide section 10, the yarn suction section 4 located directly above the first guide section 10, and the oil supply section 2 located directly above the yarn suction section 4 can also be suppressed, resulting in a lower overall height for the spinning traction device 1. As a result, it is no longer necessary to separate the single-layer working area vertically and vertically, and to assign operators to each working area separately, as in the past. One operator can perform the yarn hanging operation, thus shortening the yarn hanging operation time and saving manpower.

[0081] The filament 100 fed from the first filament feed roller 20 travels toward the stretching section 28. The winding angle of the filament 100 toward the first filament feed roller 20 is less than 360 degrees.

[0082] Multiple yarns 100 spun downwards from the spinning machine not only contact the individual roller surfaces of the multiple direction-changing rollers 10A to 10L, but are also wound at a winding angle of, for example, 45 degrees or more and less than 90 degrees. In particular, by positioning the first yarn feed roller 20 in the opposite direction to the direction-changing roller 10G in the X direction and minimizing the angle α, the winding angle of the yarns toward each direction-changing roller 10A to 10L can be increased, thereby increasing the gripping force between the yarns 100 and each direction-changing roller 10A to 10L. Therefore, tension can be applied to the yarns 100 between the multiple direction-changing rollers 10A to 10L and the first yarn feed roller 20, stabilizing the travel of the yarns 100 downstream of the multiple direction-changing rollers 10A to 10L. Furthermore, since the conventional yarn guide for fine-tuning the yarn tension is unnecessary, the oil supply unit 2 and the yarn attraction unit 4 can be positioned lower than the spinning traction device equipped with the yarn guide. Furthermore, the direction of travel of the yarn 100 can be changed by the rollers, thus minimizing the burden on the yarn 100. In addition, when the yarn separation position on the circumferential surface of the multiple direction-changing rollers 10A to 10L is lower in the vertical direction than the yarn entry position on the circumferential surface of the first yarn conveying roller 20, the winding angle that contacts the roller surface of each of the multiple direction-changing rollers 10A to 10L exceeds 90 degrees.

[0083] The multi-directional changing rollers 10A to 10L are equipped with multiple motors corresponding to each roller (described later). Figure 10 (Motor 76 shown). When the first thread conveying roller 20 is positioned at an offset position relative to the first guide section 10 and the tensioning section 28 in the opposite direction to the X direction, the distance (i.e., thread length) from each direction changing roller 10A to 10L to the first thread conveying roller 20 is different, and the tension of each of the multiple threads 100 may be different. Therefore, by enabling the multiple direction changing rollers 10A to 10L to be driven independently, the thread conveying speed is stabilized, and even when the thread lengths are different, deviations in thread tension can be suppressed.

[0084] Next, refer to Figure 4 The positional relationships between the multiple oil supply units 2, the multiple wire attraction units 4, and the multiple direction changing rollers 10A to 10L are explained. Figure 4 This is an example of a top view showing multiple oil supply sections 2, multiple wire suction sections 4, and a first wire conveying roller 20.

[0085] like Figure 4 As shown, the oil supply unit 2 consists of multiple oil supply units 2A to 2L. Figure 4 On the paper surface, along the left-right direction and in the Y direction (i.e., with the take-up axis 84 (refer to) Figure 1 (and the two orthogonal directions in the vertical direction) are arranged in a row at equal intervals and staggered. Furthermore, although in Figure 4 As shown in the middle, each of the oil supply sections 2A to 2L has a wire suction section 4A to 4L located directly below it (see reference). Figure 3 In addition, similar to the direction-changing rollers 10A to 10L, the oil supply sections 2A to 2F are also... Figure 4 The oil supply units are arranged from left to right on the paper, with oil supply sections ranging from 2G to 2L. Figure 4 The paper is arranged from right to left.

[0086] In addition, although Figure 4 The first guide section 10 (multiple direction-changing rollers 10A-10L) is not shown, but each direction-changing roller 10A-10L is arranged directly below each of the yarn attraction sections 4A-4L. Therefore, the multiple direction-changing rollers 10A-10L are also arranged in a row at equal intervals along the Y direction. As a result, the multiple yarns 100 spun from the spinning machine are staggered relative to each other in the Y direction in a parallel manner when viewed from above, preventing the yarns from interfering with or tangling. In particular, in this embodiment, the vertical distance between the first guide section 10 and the stretching section 28 is reduced, but even in this case, the multiple yarns 100 can travel in parallel, preventing them from interfering with or tangling. Furthermore, yarn feeding can be easily performed on the yarn guide (not shown) and winding device (not shown) arranged in the yarn channel between the multiple direction-changing rollers 10A-10L and the distribution rollers 70A-70L to maintain the yarn spacing. However, this is not a limitation. Between the multiple-direction changing rollers 10A to 10L and the distribution rollers 70A to 70L, it is not necessary to have a guide or winding device to maintain the yarn spacing.

[0087] Furthermore, the arrangement of the multiple oil supply sections 2A to 2L and the multiple wire suction sections 4A to 4L is not described as "arranged staggered along the X direction and Y direction" but rather as "in..." Figure 4 The reason for stating that the paper shows the arrangement "along the left and right directions and offset in the Y direction" is that the X direction refers to a single direction. That is, this avoids a mismatch between the description of "offset in the Y direction" and the statement "along the X direction" if "along the X direction" is interpreted as arranged vertically along that single direction. (Refer to...) Figure 2 as well as Figure 3 The description does not state "arranged in a column along the X direction" but instead states "in Figure 2 Arranged in a column along the left and right direction on the paper" or "on Figure 3 The reason for "arranging them in a column along the left and right directions on the paper" is the same. That is, it is to avoid being interpreted as not being separated in the Y direction when it is written as "arranged in a column along the X direction".

[0088] Furthermore, the number of multiple oil supply units 2, multiple wire suction units 4, multiple direction changing rollers 10A to 10L, multiple traverse devices 85, and multiple bobbins 86 is not particularly limited.

[0089] [2-2. Tensioning section]

[0090] Figure 5 This is an example of a side view showing the periphery of the stretching section 28. For example... Figure 5 As shown, the stretching section 28 mainly includes: a plurality of preheating rollers 31 for heating the yarn 100 before stretching; a plurality of stretching rollers 41 disposed downstream of the plurality of preheating rollers 31; and a plurality of heat setting rollers 51 disposed downstream of the plurality of stretching rollers 41 for conditioning the yarn 100 after stretching.

[0091] In addition, multiple preheating rollers 31, multiple stretching rollers 41 and multiple heat setting rollers 51 are respectively housed in an insulated box (without reference symbols), which would not normally appear in the accompanying drawings, but are appropriately illustrated in the various figures referenced in this specification.

[0092] However, conventionally, heating length is ensured by winding the yarn multiple times on a long roller with a relatively large roller width. In the spinning traction device 1 of this embodiment, a short roller with a smaller roller width than conventionally is used, and the winding of the guiding roller is less than one turn. However, in order to ensure heating length while the winding of the guiding roller is less than one turn, a larger number of rollers is required than before. In particular, for example, in spinning traction devices for producing industrial materials with a denier of 300 or higher, a greater heating length is required compared to spinning traction devices for clothing yarns. Therefore, in the spinning traction device 1 of this embodiment, by arranging multiple preheating rollers 31, multiple stretching rollers 41, and multiple heat-setting rollers 51 horizontally in a straight line along the X direction on the same floor, it is possible to ensure heating length while the winding of the guiding roller is less than one turn (the winding angle of the guiding roller is less than 360 degrees), and to reduce the height of the stretching section 28. Furthermore, the multiple preheating rollers 31, multiple stretching rollers 41, and multiple heat-setting rollers 51 correspond to the "multiple rollers" of the present invention.

[0093] The yarn conveying speed of at least the upstream stretching roller 41 among the plurality of stretching rollers 41 is greater than the yarn conveying speed of the downstream preheating roller 31 among the plurality of preheating rollers 31. Therefore, the yarn 100 is stretched between the downstream preheating roller 31 among the plurality of preheating rollers 31 and the upstream stretching roller 41 among the plurality of stretching rollers 41.

[0094] The surface temperature of the plurality of preheating rollers 31 is set to a temperature above the glass transition point of the filament 100 (e.g., 90°C). The surface temperature of the plurality of first stretching rollers 41 is set to a temperature higher than the surface temperature of the preheating rollers 31 (e.g., 110°C). The surface temperature of the plurality of heat setting rollers 51 is set to a temperature higher than the surface temperature of the stretching rollers 41 (e.g., 130°C).

[0095] Furthermore, in this embodiment, the surface temperature of all the rolls of the plurality of preheating rolls 31 is raised, but this is not a limitation; at least one roll may be raised while the surface temperature of the remaining rolls is not raised. Similarly, in this embodiment, the surface temperature of all the rolls of the plurality of stretching rolls 41 and the plurality of heat-setting rolls 51 is raised, but this is not a limitation; at least one roll of each may be raised while the surface temperature of the remaining rolls is not raised. Furthermore, the plurality of preheating rolls 31 are not necessarily set to the same surface temperature. The plurality of preheating rolls 31 may also be set to different surface temperatures. Similarly, the plurality of stretching rolls 41 and the plurality of heat-setting rolls 51 may be set to the same surface temperature or different surface temperatures.

[0096] [2-3. Softening Section]

[0097] Figure 6 This is an example of a side view showing the periphery of the buffer section 60, the distribution section 70, and the winding section 8. For example... Figure 6 As shown, the easing section 60 is positioned directly above the heat setting roller 51.

[0098] The easing section 60 has a first easing roller 61 and a second easing roller 62 disposed downstream of the first easing roller 61 in the direction of yarn travel. Both the first easing roller 61 and the second easing roller 62 are rollers whose axial direction is approximately orthogonal to the direction of yarn travel in the yarn channel when viewed from above (i.e., the Y direction).

[0099] The yarn 100 fed from the downstream heat setting roller 51 of the plurality of heat setting rollers 51 travels in the order of the first easing roller 61 and the second easing roller 62. Furthermore, the second easing roller 62 corresponds to the "guide roller" of the present invention.

[0100] The first softening roller 61 and the second softening roller 62 are staggered in the vertical direction. Furthermore, the first softening roller 61 and the second softening roller 62 are staggered in the X direction, with the first softening roller 61 positioned on the X-direction side and the second softening roller 62 positioned on the opposite side of the X-direction. By arranging the first softening roller 61 and the second softening roller 62 in this way, the height of the second softening roller 62 can be suppressed, and the wire-coating operation onto the second softening roller 62 can be facilitated.

[0101] The winding angles of the yarn 100 toward the first softening roller 61 and the second softening roller 62 are both less than 360 degrees. The surface temperatures of the softening rollers 61 and 62 are set lower than the temperature of the heat-setting roller 51 (e.g., 100°C) to mitigate the internal deformation of the yarn 100. However, the first softening roller 61 and the second softening roller 62 do not necessarily have to be set to the same surface temperature; different surface temperatures can be set for each softening roller 61 and 62.

[0102] Furthermore, in this embodiment, both the first softening roller 61 and the second softening roller 62 raise the surface temperature of the rollers, but this is not a limitation. For example, at least one of the first softening roller 61 and the second softening roller 62 may raise the surface temperature while the surface temperatures of the other rollers remain unchanged.

[0103] The yarn 100 fed from the second easing roller 62, which is located downstream of the yarn travel direction in the easing section 60, is guided toward the distribution section 70. The easing section 60 and the distribution section 70 correspond to the "second guide section" of the present invention.

[0104] [2-4. Distribution Department]

[0105] like Figure 6 As shown, the distribution section 70 includes a plurality of distribution rollers 70A to 70F. The plurality of distribution rollers 70A to 70F are arranged horizontally in a straight line in the X direction in the order of distribution roller 70A, distribution roller 70B, distribution roller 70C, distribution roller 70D, distribution roller 70E, and distribution roller 70F.

[0106] Furthermore, multiple bobbins 86A to 86F can be mounted on one winding shaft 84 of the first winding device 81. In this embodiment, the multiple bobbins 86A to 86F are mounted on the winding shaft 84 of the first winding device 81 in the X direction in the order of bobbins 86A, 86B, 86C, 86D, 86E, and 86F.

[0107] Multiple distribution rollers 70A to 70F correspond to multiple bobbins 86A to 86F. Each distribution roller 70A to 70F changes the direction of travel of the yarn 100 fed from the second buffer roller 62 to a downward direction. In this way, multiple yarns 100 are fed from each distribution roller 70A to 70F to the corresponding bobbins 86A to 86F for each yarn 100.

[0108] Multiple bobbins 86A to 86F respectively wind up the yarn 100, whose travel direction has been changed by the corresponding distribution rollers 70A to 70F, to form a winding package. Furthermore, above each of the multiple bobbins 86A to 86F, multiple traversing devices 85A to 85F corresponding to each bobbin 86A to 86F are arranged. However, in Figure 6In this document, reference symbols are appropriately added only to the traversing devices 85A and 85F, while reference symbols for the traversing devices 85B to 85E are omitted. Furthermore, above each of the traversing devices 85A to 85F, there are multiple distribution rollers 70A to 70F corresponding to the multiple traversing devices 85A to 85F, i.e., the multiple bobbins 86A to 86F.

[0109] Figure 7 This is an example of a top view showing the perimeter of the distribution section 70. For example... Figure 7 As shown, the distribution section 70 includes multiple distribution rollers 70G to 70L in addition to the aforementioned multiple distribution rollers 70A to 70F. Multiple filaments 100 fed from the second softening roller 62 are conveyed toward the distribution rollers 70A to 70F and toward the distribution rollers 70G to 70L.

[0110] As described above, the plurality of distribution rollers 70A to 70F correspond to the plurality of bobbins 86A to 86F mounted on the winding shaft 84 of the first winding device 81. Conversely, the plurality of distribution rollers 70G to 70L correspond to the plurality of bobbins 86A to 86F mounted on the second winding device 91 (see reference 86F). Figure 1 The multiple bobbins (not shown) of the take-up shaft 84 correspond to each other. Therefore, each distribution roller 70G to 70L, like each distribution roller 70A to 70F, changes the direction of travel of the yarn 100 fed from the second softening roller 62 to downward.

[0111] Thus, from the stretching part 28 (refer to) Figure 6 The downstream heat setting roller 51 (refer to) Figure 6 The yarn 100 fed from the heat-setting roller 51 is conveyed to the take-up section 8 via the easing section 60 and the distribution section 70. That is, the yarn 10 fed from the downstream heat-setting roller 51 travels temporarily upward above the stretching section 28 and is wound into the take-up section 8 via the easing section 60 and the distribution section 70. Therefore, even when the take-up section 8 and the stretching section 28 are arranged horizontally on the same floor, the yarn 100 fed from the stretching section 28, i.e., the downstream heat-setting roller 51, can be wound into the take-up section 8. In other words, by winding the yarn 100 fed from the downstream heat-setting roller 51 into the take-up section 8 via the easing section 60 and the distribution section 70, which are arranged at a position higher than the take-up section 8, it is possible to facilitate the horizontal arrangement of the stretching section 28 and the take-up section 8 on the same floor. As a result, the height of the stretching section 28 can be suppressed to achieve a low height, and in turn, the height of the spinning traction device 1 can be suppressed to achieve a low height.

[0112] [2-5. Thread channel from the buffer section to the distribution section]

[0113] Next, refer to Figure 7 The thread channel from the buffer section 60 to the distribution section 70 will be described. For example... Figure 7As shown, multiple (e.g., 12) threads 100 fed from the second softening roller 62 travel along any one of multiple thread channels 96A to 96L that are separated in a direction orthogonal to the thread channels when viewed from above.

[0114] Thread path 96A is the path of thread 100 traveling toward distribution roller 70A. Thread 100 traveling in thread path 96A is thread 100 fed from direction-changing roller 10A. Similarly, thread paths 96B to 96L are the paths of thread 100 traveling toward distribution rollers 70B to 70L, respectively. Thread 100 traveling in thread paths 96B to 96L are thread 100 fed from direction-changing rollers 10B to 10L, respectively.

[0115] Silk channels 96A to 96F are separated from each other in the Y direction. Similarly, silk channels 96G to 96L are separated from each other in the Y direction. Furthermore, as shown in reference... Figure 4 As described, multiple directional changing rollers 10A to 10L (refer to...) Figure 3 The multiple threads 100 are staggered in the Y direction. Furthermore, multiple threads 100 originate from the first guide portion 10 (see reference 10). Figure 2 Between the first guide section 10 and the second buffer roller 62, the travel direction is such that while maintaining parallelism, the travel direction when viewed from above is only the X direction. Therefore, from the first guide section 10 (see reference 10) Figure 2 ) to the stretching section 28 (refer to) Figure 2 Between the rollers, the yarn 100 can travel in a manner in which the yarn passage is not separated in the axial direction of each roller (direction changing rollers 10A to 10L, first yarn conveying roller 20, multiple preheating rollers 31, multiple first stretching rollers 41, multiple heat setting rollers 51, multiple softening rollers 61, 62).

[0116] [2-6. Positional relationship between the buffer section and the distribution section]

[0117] Next, the positional relationship between the buffer section 60 and the distribution section 70 will be explained when the multiple distribution rollers 70A to 70F are arranged horizontally in a straight line in the X direction. More specifically, the height positional relationship between the second buffer roller 62 on the downstream side of the buffer section 60 and each distribution roller 70A to 70F will be explained.

[0118] Figure 8 This is an example of a side view of the second easing roller 62 and each of the distribution rollers 70A to 70F. As with the spinning traction device 1 of this embodiment, from the stretching section 28 (see reference...) Figure 6 When multiple (e.g., 12 in this embodiment) threads 100 are wound onto the take-up section 8 via the buffer section 60 and the distribution section 70, the following requirement must be met. For example, it is necessary to ensure that the distribution rollers 70F and 70L (refer to...) furthest from the second buffer roller 62... Figure 7The yarn 100, up to the contact point, is connected to other distribution rollers 70A-70E, 70G-70K (refer to...). Figure 7 Other rolls upstream of the second buffer roll 62 (e.g., the first buffer roll 61 (e.g., refer to...) Figure 6 The roller surfaces do not contact each other. Therefore, it is necessary to configure the buffer section 60 (first buffer roller 61, second buffer roller 62) and the distribution rollers 70A to 70L within the range that meets this requirement.

[0119] However, the lower limit of the height direction of the distribution rollers 70A to 70F can be configured, for example, according to the traverse device 85A to 85F and the bobbin 86A to 86F (all refer to Figure 8 The relative positional relationship between the distribution rollers 70A to 70F and the distribution rollers 70A to 70F is used to determine the height position of the second softening roller 62. Therefore, in order to suppress the height of the second softening roller 62, it is preferable to determine the height position of the second softening roller 62 within the range that satisfies the above requirements, based on the arrangement of the distribution rollers 70A to 70F at the lower limit or near the lower limit in the height direction. Although it is also based on the distance from the second softening roller 62 to each distribution roller 70A to 70L (see reference...) Figure 7 The distance from the contact point varies, but in this embodiment, the second softening roller 62 is configured such that the acute angle formed by the direction of the yarn travel of the yarn 100 fed from the second softening roller 62 to each distribution roller 70A-70F and the horizontal plane is, for example, greater than 0 degrees and less than 20 degrees. Thus, by positioning the second softening roller 62 at a position as low as possible, the yarn loading operation onto the second softening roller 62 can be prevented from becoming a high-altitude operation. "The acute angle formed by the direction of the yarn travel of the yarn 100 fed from the second softening roller 62 to each distribution roller 70A-70F and the horizontal plane" is equivalent to... Figure 9 The angle β shown. Furthermore... Figure 9 This is an example of a schematic diagram showing the acute angle β formed by the direction of travel of the yarn 100 fed from the second buffer roller 62 to the distribution roller 70A and the horizontal plane. Figure 9 As an example, the diagram shows distribution roller 70A among a plurality of distribution rollers 70A to 70F. In this embodiment, the second softening roller 62 is configured such that the acute angle β formed by the direction of the yarn 100 fed from the second softening roller 62 to each distribution roller 70A to 70F and the horizontal plane is, for example, greater than 0 degrees and less than 20 degrees.

[0120] However, as described above, the distribution rollers 70A to 70F are arranged horizontally in a straight line facing the X direction. Therefore, the angle β of the acute angle formed by the direction of the yarn 100 fed from the second softening roller 62 to each distribution roller 70A to 70F and the horizontal plane varies depending on the distance from the second softening roller 62 to each distribution roller 70A to 70F. Specifically, the closer the distance to the second softening roller 62, the larger the angle β. That is, the angle β is the largest when the acute angle formed by the direction of the yarn 100 fed from the second softening roller 62 to the distribution roller 70A and the horizontal plane is the same as the angle β of the acute angle formed by the direction of the yarn 100 fed from the second softening roller 62 to the distribution roller 70F and the horizontal plane. Therefore, when the angle β is set to be greater than 0 degrees and less than 20 degrees, the second softening roller 62 can be configured such that the angle β formed by the direction of the yarn 100 fed from the second softening roller 62 to the distribution roller 70F and the horizontal plane is greater than 0 degrees, and the acute angle β formed by the direction of the yarn 100 fed from the second softening roller 62 to the distribution roller 70A and the horizontal plane is less than 20 degrees.

[0121] In addition, each distribution roller 70A~70F and each distribution roller 70G~70L (refer to) Figure 7 They are in a paired relationship. Therefore, the angle β formed by the direction of the silk thread 100 fed from the second softening roller 62 to each distribution roller 70G to 70L and the horizontal plane is almost the same as the angle β formed by the direction of the silk thread 100 fed from the second softening roller 62 to each distribution roller 70A to 70F and the horizontal plane.

[0122] [2-7. Installation method of distribution roller]

[0123] Next, refer to Figure 10 The installation method of each distribution roller 70A to 70L is explained. Figure 10 This is an example of a cross-sectional view taken at a position closer to the X-direction than each distribution roller 70A-70L, along a direction orthogonal to the X-direction. More specifically, Figure 10 (A) is Figure 8 The cross-sectional view along line A-A is shown. Figure 10 (B) is Figure 8 The cross-sectional view of line B-B is shown. Figure 10 (C) is Figure 8 The cross-sectional view along the C-C line is shown. Figure 10 (D) is Figure 8 The cross-sectional view of the D-D line is shown.

[0124] Figure 10 (E) is Figure 8 The cross-sectional view along the E-E line is shown. Figure 10 (F) is Figure 8 The cross-sectional view of the F-F line is shown.

[0125] like Figure 10 As shown in (A) to (F), the axial directions of the distribution rollers 70A to 70L are all inclined relative to the horizontal direction. The reason for inclining the axial directions of the distribution rollers 70A to 70L relative to the horizontal direction is that each of the multiple distribution rollers 70A to 70L can avoid the yarn 100 traveling along the yarn channels 96A to 96L corresponding to the other distribution rollers 70A to 70L. Furthermore, even with this simple configuration of inclining the axial directions of the distribution rollers 70A to 70L relative to the horizontal direction, contact between the yarn and the roller surface can be avoided.

[0126] Furthermore, if the purpose is to prevent the yarn 100 from contacting the roller surfaces of other distribution rollers 70A-70E, 70G-70K from the contact point with the furthest distribution rollers 70F and 70L, then the axial direction of distribution rollers 70F and 70L must be tilted relative to the horizontal direction.

[0127] When the installation method of the distribution rollers 70A to 70L is described in detail, the distribution rollers 70A to 70F are installed on one side of the mounting frame 72. Figure 10 Mounting surface 72a (right side of the paper), distribution rollers 70G to 70L are mounted on the other side of mounting frame 72. Figure 10 The mounting surface 72b (on the left side of the paper). The mounting frame 72 is, in Figure 10 In the paper, one mounting surface 72a is configured to descend to the right from top to bottom, and the other mounting surface 72b is configured to descend to the left from top to bottom. Distributor rollers 70A to 70F are mounted axially orthogonal to the mounting surface 72a on one side, so the axial direction of distributor rollers 70A to 70F is an upward direction from the base end of one side of the mounting surface 72a to the front end opposite the base end. Similarly, distributor rollers 70G to 70L are mounted axially orthogonal to the mounting surface 72b on the other side, so the axial direction of distributor rollers 70G to 70L is an upward direction from the base end to the front end. In this embodiment, distributor rollers 70A to 70F are mounted on the mounting surface 72a on one side at an angle of approximately 30 degrees to the acute angle formed by the axial direction and the horizontal direction. On the other hand, the distribution rollers 70G to 70L are mounted on the mounting surface 72b on the other side in such a way that the angle between the acute angle formed by the axial direction and the horizontal direction is approximately 30 degrees.

[0128] Thus, by tilting the distribution rollers 70A to 70L upwards from the base end to the front end, it is possible to prevent the surface of other distribution rollers from contacting the yarn 100 until it reaches the corresponding distribution roller. As a result, multiple yarns 100 can enter the distribution rollers 70A to 70F and the distribution rollers 70G to 70L in parallel, and the height of the first buffer roller 61 and each distribution roller 70A to 70L can be suppressed.

[0129] Furthermore, when the distribution rollers 70A to 70L are horizontally arranged along the thread channels (i.e., the X direction) of the multiple threads 100, at the same distance from the second buffer roller 62, the thread 100 traveling along the thread channels of the distribution rollers that are further away from the second buffer roller 62 travels at a higher position. Therefore, according to textbook theory, even without tilting the distribution rollers 70A to 70L, it can be considered that the threads 100 do not contact the surfaces of other distribution rollers. However, in reality, due to the bending and vibration of the threads 100, the threads 100 may come into contact with the surfaces or other parts of other distribution rollers even without tilting the distribution rollers 70A to 70L. Therefore, in this embodiment, the distribution rollers 70A to 70L are installed with the axial direction pointing upwards from the base end to the front end. Therefore, in the thread path from the thread 100 to the corresponding distribution roller, the thread paths 96B to 96F and 96H to L of each thread can be ensured, thereby ensuring space for the thread 100 to travel even if it flexes or vibrates. In particular, the thread 100 can travel in a manner that does not come into contact with the roller surfaces of the other distribution rollers 70A to 70E and 70G to 70K up to the contact point of the distribution rollers 70F and 70L, which are the furthest from the second buffer roller 62.

[0130] Furthermore, the distribution rollers 70A to 70L are equipped with motors 76 corresponding to each roller. In the spinning traction device 1 of this embodiment, since the distance from the second easing roller 62 to each distribution roller 70A to 70L is different, the tension may vary for each of the multiple filaments 100 at a position downstream of each distribution roller 70A to 70L. When the tension varies for each of the multiple filaments 100, it is difficult to maintain a constant quality of the winding and packaging based on the wound bobbin. Therefore, by enabling the multiple distribution rollers 70A to 70L to be driven independently, the tension difference of the multiple filaments 100 downstream of each distribution roller 70A to 70L can be reduced, thereby stabilizing the quality of the winding and packaging.

[0131] [3. Effects]

[0132] According to the spinning traction device 1 of this embodiment described above, multiple filaments 100 from the stretching section 28 are conveyed to the winding section via the second softening roller 62 and the distribution section 70. Therefore, the stretching section 28 and the winding section 8 can be horizontally arranged on the same floor, with the axial direction of the winding shaft 84 parallel to the direction of travel of the filaments 100 in the stretching section 28 when viewed from above. As a result, it is not necessary to separate the work area on one floor vertically and assign operators to each work area as in the past; the filament hanging operation can be performed by a single operator, thus shortening the filament hanging operation time and saving manpower.

[0133] Furthermore, the second softening roller 62 and the distribution rollers 70A to 70L are configured such that the angle β formed by the direction of the yarn travel of the yarn 100 fed from the second softening roller 62 and the horizontal plane is 0 degrees or more and within 20 degrees. However, the lower limit of the height direction of the distribution rollers 70A to 70L is determined, for example, by their relative positional relationship with the plurality of traversing devices 85A to 85F, bobbins 86A to 86F, etc. Therefore, by configuring the second softening roller 62 and the distribution rollers 70A to 70L such that the angle β formed by the direction of the yarn travel of the yarn 100 fed from the second softening roller 62 and the horizontal plane is 0 degrees or more and within 20 degrees, the height of the second softening roller 62 and the distribution rollers 70A to 70L can be suppressed.

[0134] Furthermore, the distribution rollers are arranged in a row along the yarn path from the second softening roller 62 to the distribution rollers. Additionally, the yarn path from the second softening roller 62 to the distribution rollers 70A-70L has multiple yarn paths 96A-96L formed corresponding to the distribution rollers 70A-70L, separated in a direction orthogonal to the yarn path when viewed from above. The distribution rollers 70A-70L are then configured to avoid the yarn paths 96A-96L corresponding to other distribution rollers 70A-70L. Specifically, the axial direction of the distribution rollers 70A-70L is inclined relative to the horizontal direction. Therefore, the yarn 100 fed from the second softening roller 62 can be prevented from contacting the roller surfaces of other distribution rollers 70A-70L.

[0135] Furthermore, multiple motors 76 are provided, each corresponding to one of the multiple distribution rollers 70A to 70L. Therefore, each of the multiple distribution rollers 70A to 70L can be driven independently, reducing the tension difference among the multiple filaments 100 downstream of the multiple distribution rollers 70A to 70L. As a result, the quality of the winding and packaging can be stabilized. In particular, since the distances of each of the multiple distribution rollers 70A to 70L from the second buffer roller 62 are different, tension differences are easily generated. However, since multiple motors 76 are provided, each corresponding to one of the multiple distribution rollers 70A to 70L, the tension difference among the multiple filaments 100 downstream of the multiple distribution rollers 70A to 70L can be reduced and stabilized.

[0136] [4. Variations]

[0137] Next, various modifications to the spinning traction device 1 of this embodiment will be described. When describing these modifications, cases having the same configuration as the above embodiment will be given the same reference numerals, and their descriptions will be omitted as appropriate.

[0138] [4-1. First Variation]

[0139] In the above embodiments, for example Figure 2 As shown, the stretching section 28 is horizontally arranged on the same floor as the winding section 8. The yarn 100 fed from the stretching section 28 is conveyed to the winding section 8 via the easing section 60 and the distribution section 70 arranged above the stretching section 28, but this is not a limitation. That is, the easing section 60 is not necessarily arranged above the stretching section 28.

[0140] Figure 11 This is an example of a schematic side view showing the spinning drawing device 1A of the first modified example. Figure 11 In the spinning traction device 1A shown, a easing section 60 is arranged downstream of the stretching section 28. Furthermore, second yarn feed rollers 94 and 95 are arranged above the easing section 60. The yarn 100 fed from the easing section 60 is then fed to the winding section 8 via the second yarn feed rollers 94 and 95 and the distribution section 70. Even in this case, the yarn 100 fed from the easing section 60 can temporarily travel in a direction above the stretching section 28 and the easing section 60, and be fed to the winding section 8 via the second yarn feed rollers 94 and 95 and the distribution section 70. Therefore, even if the winding section 8 and the stretching section 28 are arranged horizontally on the same floor, the yarn 100 fed from the stretching section 28 can be wound into the winding section 8. Furthermore, the number of second yarn feed rollers is not limited to two. It can be one or more. The number of second thread conveying rollers can be appropriately selected based on the contact angle and contact area of ​​the thread 100 fed from the easing section 60 wound around the circumference of the second thread conveying roller. In the spinning traction device 1A of the first modified example, the second thread conveying roller corresponds to the "guide roller" of the present invention.

[0141] [4-2. Second variation]

[0142] In the above embodiments, for example Figure 10As shown, the distribution rollers 70A to 70L are mounted with their axial direction pointing upwards from the base end to the front end. By mounting the distribution rollers 70A to 70L in this way, for example, it is possible to prevent the yarn 100 from contacting the contact point of the second buffer roller 62 to the furthest distribution rollers 70F and 70L with the roller surfaces of other distribution rollers 70A to 70E and 70G to 70K. However, the shape of the distribution rollers 70A to 70L and the mounting method of the distribution rollers 70A to 70L are not necessarily... Figure 10 The shape and installation method shown can also be, for example, Figure 12 The shape and installation method are shown.

[0143] Figure 12 This is a diagram illustrating a second variation where deformations were applied to the shape and mounting method of the distribution roller. Figure 12 In this process, by changing the shape of the distribution rollers, for example, the yarn 100 from the contact point of the second buffer roller 62 to the farthest distribution rollers 77F and 77L does not contact the roller surfaces of other distribution rollers 77A to 77E and 77G to 77K.

[0144] Specifically, Figure 12 The distribution rollers 77A to 77L shown are distribution rollers with a tapered cross-section that increase in diameter from the base end to the front end, and are mounted on one side of the mounting frame 72 with their axial direction aligned with the Y direction. Figure 12 Mounting surface 72a (right side of the paper) or the other side ( Figure 12 The mounting surface 72b (on the left side of the paper). Even in this case, the height of the roller surface can be changed according to the position in the Y direction, ensuring that there is enough space for the yarn 100 to travel in the yarn path where the yarn 100 reaches the corresponding distribution roller. As a result, the yarn 100 from the second buffer roller 62 to the contact point of the furthest distribution rollers 77F and 77L can be kept away from the roller surfaces of other distribution rollers 77A to 77E and 77G to 77K.

[0145] Furthermore, regarding the distribution rollers 77F and 77L, similar to the distribution rollers that are mounted axially at an angle, they do not necessarily have to be distribution rollers with a conical cross-section.

[0146] [4-3. Third variation]

[0147] Figure 13 This diagram illustrates a third modification, in which the shape and mounting method of the distribution roller are modified according to the same principle as the second modification. Figure 13 In this way, for example, the yarn 100 from the contact point of the second easing roller 62 to the farthest distribution rollers 78F and 78L is also prevented from contacting the roller surfaces of other distribution rollers 78A to 78E and 78G to 78K.

[0148] Specifically, Figure 13 The distribution rollers 78A to 78L shown are stepped distribution rollers whose diameter increases in a stepped manner from the base end to the front end, and are mounted on one side of the mounting frame 72 with the axial direction in the Y direction. Figure 13 Mounting surface 72a (right side of the paper) or the other side ( Figure 13 The mounting surface 72b (on the left side of the paper). Even in this case, the height of the roller surface can be changed according to the position in the Y direction, ensuring that there is enough space for the yarn 100 to travel in the yarn path until the yarn 100 reaches the corresponding distribution roller. As a result, for example, the yarn 100 can be prevented from contacting the roller surfaces of other distribution rollers 78A to 78E, 78G to 78K from the contact point of the second buffer roller 62 to the furthest distribution rollers 78F and 78L.

[0149] Furthermore, regarding the distribution rollers 78F and 78L, similar to the distribution rollers that are mounted axially at an angle, they do not necessarily have to be stepped distribution rollers.

[0150] Furthermore, the shape and installation method of the distribution rollers do not all have to be the same. For example, they may include a distribution roller that is installed axially at an angle as described in this embodiment, a distribution roller with a conical cross-section as described in Modified Example 2, and a distribution roller with steps as described in Modified Example 3.

[0151] [4-4. Fourth variation]

[0152] In the above embodiments, for example Figure 8 As shown, the distribution rollers 70A to 70F are arranged horizontally in a straight line facing the X direction, but this is not a limitation; they can also be... Figure 14 As shown in the diagram. Figure 14 This is a diagram illustrating a fourth variation in which the configuration of the distribution rollers 70A to 70F has been altered. For example, as shown... Figure 14 As shown, the distribution rollers 70A to 70F can also be arranged along the X direction by changing their respective height positions. That is, for example, as long as the yarn 100 traveling along the yarn path 96F from the second buffer roller 62 to the contact point of the furthest distribution roller 70F does not come into contact with the roller surfaces of the other distribution rollers 70A to 70E, the height position of the distribution rollers 70A to 70F may not be horizontal. Furthermore, in Figure 14 Although not shown in the diagram, the same applies to the distribution rollers 70G to 70L. Thus, according to... Figure 14 The configuration shown is simple, which only involves changing the height position of the multiple distribution rollers 70A to 70F. This configuration ensures that the yarns 100 fed from the second buffer roller 62 do not come into contact with the roller surfaces of the other distribution rollers.

[0153] When the distribution rollers 70A to 70F are as follows Figure 14 When the height positions of the yarns are changed as shown and they are arranged along the X direction, the acute angle β formed by the direction of yarn travel of the yarn 100 fed from the second buffer roller 62 to each distribution roller 70A to 70F and the horizontal plane can be 0 degrees or less.

[0154] Figure 15 This is a schematic diagram illustrating an example of the positional relationship between the first buffer roller 61, the second buffer roller 62, and the distribution rollers 70A to 70F when the height positions of the distribution rollers 70A to 70F are changed. Figure 15 (A) is a schematic diagram representing the first configuration mode. Figure 15 (B) is a schematic diagram representing the second configuration mode. Figure 15 (C) is a schematic diagram representing the third configuration mode.

[0155] Figure 15 In all configurations shown in (A) to (C), from the first to the third configuration, the yarn 100 from the contact point of the second softening roller 62 to the distribution roller 70F does not contact the roller surfaces of the other distribution rollers 70A to 70E and the first softening roller 61. Regardless of... Figure 15 In all three configuration modes (A) to (C), the first to third configuration modes ensure sufficient space for the yarn 100 to travel along the yarn path up to the corresponding distribution roller. Therefore, the yarn 100 from the contact point between the second softening roller 62 and the distribution roller 70F can be kept away from the surfaces of the other distribution rollers 70A to 70E and the first softening roller 61. Furthermore, in Figure 15 The first configuration mode shown in (A) and Figure 15 In the third configuration mode shown in (C), the angle β formed by the acute angle between the direction of the yarn 100 fed from the second buffer roller 62 to each distribution roller 70A to 70F and the horizontal plane is made to be less than 0 degrees.

[0156] Figure 16 This is a schematic diagram illustrating another example of the positional relationship between the first buffer roller 61, the second buffer roller 62, and the distribution rollers 70A to 70F when the height positions of the distribution rollers 70A to 70F are changed. Figure 16 (A) is a schematic diagram representing the fourth configuration mode. Figure 16 (B) is a schematic diagram representing the 5th configuration mode.

[0157] Figure 16 The fourth configuration shown in (A) involves the yarn 100, from the contact point of the second buffer roller 62 to the distribution roller 70F, contacting the roller surfaces of the other distribution rollers 70A to 70E. Furthermore, Figure 16In the fifth configuration shown in (B), the yarn 100 from the contact point of the second softening roller 62 to the distribution roller 70F is in contact with the roller surface of the first softening roller 61. Therefore, the positional relationship of the first softening roller 61, the second softening roller 62, and the distribution rollers 70A to 70F cannot be adopted for such fourth and fifth configurations.
