Summary of the Invention

Problems to be Solved by the Invention

[0005] When hanging a plurality of yarns spun from a spinning device on a spinning take-up device, a suction gun that sucks the plurality of yarns together is used. Therefore, when hanging the yarns on the yarn path regulating guide as described above, a suction gun that sucks the plurality of yarns together is naturally used. Conventionally, the operation of hanging the yarns on the yarn path regulating guide has been performed manually while the operator holds the yarn suction port of the suction gun at an appropriate working position.

[0006] <000003,However, positioning the suction gun's nozzle in the correct working location is time-consuming, and maintaining that position throughout the threading process is difficult. The longer the threading process takes, the more thread is wasted, increasing production costs.

[0007] The object of the present invention is to provide a spinning and drawing device that can easily perform the yarn threading operation on a yarn path regulating guide. [Means for solving the problem]

[0008] The first spinning take-up device is a spinning take-up device configured to wind up a plurality of yarns spun from a spinning device with a yarn winding device, and is characterized by comprising: a yarn path restricting guide having a plurality of grooves arranged in an arrangement direction perpendicular to the yarn running direction on which the plurality of yarns travel, and which restricts the movement of the plurality of yarns arranged in the arrangement direction as the plurality of yarns travel within the plurality of grooves; and a positioning unit that positions the suction port of a suction gun at a predetermined position downstream of the yarn path restricting guide in the yarn running direction, where it is possible to thread the yarn onto the yarn path restricting guide.

[0009] According to the present invention, when threading onto a thread guide, the suction nozzle of the suction gun can be positioned by the positioning unit to a predetermined position that allows threading onto the thread guide. Therefore, it does not take time to position the suction nozzle of the suction gun in the appropriate working position. Furthermore, since it is only necessary to hold the suction gun while positioning the suction nozzle on the positioning unit, the difficulty of continuously holding the suction gun during threading is also eliminated. As a result, threading onto the thread guide can be performed easily.

[0010] The spinning take-up device of the second invention is characterized in that, in the first invention, the predetermined position is determined such that, when viewed from an orthogonal direction perpendicular to both the yarn running direction and the arrangement direction, the plurality of yarns being sucked into the suction port of the suction gun positioned in the positioning part and the plurality of grooves overlap.

[0011] According to the present invention, the suction port of the suction gun is positioned by the positioning part, so that when viewed from a perpendicular direction, the multiple threads being sucked into the suction port of the suction gun positioned by the positioning part and the multiple grooves overlap. As a result, it becomes unnecessary to adjust the position of each of the multiple threads in the arrangement direction when threading the thread onto the thread guide, making the threading operation on the thread guide even easier.

[0012] The third spinning take-up device of the invention is characterized in that, in the first or second invention, a yarn sway suppression member is arranged between the yarn path regulating guide and the positioning unit in the yarn running direction, and the plurality of yarns that are sucked into the suction port of the suction gun positioned in the positioning unit come into contact with the member.

[0013] A swirling flow is generated inside the suction gun. If the thread oscillation caused by the swirling flow is transmitted to the threads running near the thread guide upstream of the positioning unit in the thread travel direction, it becomes difficult to thread the threads onto the thread guide. According to the present invention, by arranging a thread oscillation suppression member that contacts multiple threads between the thread guide and the positioning unit, it is possible to suppress the transmission of thread oscillation caused by the swirling flow generated inside the suction gun to the multiple threads running near the thread guide. This makes it even easier to thread the threads onto the thread guide.

[0014] The spinning take-up device of the fourth invention is characterized in that, in the third invention, when the suction port of the suction gun is positioned in the positioning part, when viewed from the arrangement direction, the angle formed by the plurality of yarns running upstream of the yarn sway suppressing member in the yarn running direction and the plurality of yarns running downstream of the yarn sway suppressing member in the yarn running direction is 165 degrees or less on the side where the yarn sway suppressing member is located.

[0015] According to the present invention, when viewed from the direction of arrangement, the angle between the multiple threads running upstream of the thread sway suppressing member in the thread running direction and the multiple threads running downstream of the thread sway suppressing member in the thread running direction, compared to the case where the angle on the side where the thread sway suppressing member is located is greater than 165 degrees, allows the thread sway suppressing member to be pressed more strongly against the multiple threads. As a result, thread sway caused by the swirling flow generated inside the suction gun can be more reliably suppressed from being transmitted to the multiple threads running near the thread path regulating guide.

[0016] The spinning and drawing device of the fifth invention is characterized in that, in the third or fourth invention, the yarn sway suppressing member can be retracted from the yarn paths of the plurality of yarns when the yarn is being wound by the yarn winding device.

[0017] According to the present invention, when the thread winding device winds the thread after the thread has been threaded onto the thread guide, it is possible to avoid the thread sway suppression member coming into contact with the moving thread. This prevents the quality of the thread from deteriorating due to contact with the thread sway suppression member.

[0018] The sixth invention, a spinning and drawing device, is characterized in that, in the first to fifth inventions, the positioning unit can be retracted from the thread paths of the plurality of threads when the thread is being wound by the thread winding device.

[0019] According to the present invention, when the thread is wound by the thread winding device after the thread threading operation on the thread guide has been completed, it is possible to avoid the positioning part coming into contact with the moving thread. This prevents the quality of the thread from deteriorating due to contact with the positioning part.

[0020] The spinning take-up device of the seventh invention is characterized in that, in the third or fourth invention, the positioning unit and the yarn sway suppression member are positioned so as not to overlap with the yarn paths of the plurality of yarns when the yarn is being wound by the yarn winding device.

[0021] According to the present invention, when the thread is wound by the thread winding device after the thread threading operation on the thread guide has been completed, contact between the positioning unit and the thread sway suppression member and the moving thread can be avoided. This prevents a deterioration in the quality of the thread due to contact with the positioning unit and the thread sway suppression member.

[0022] The eighth spinning take-up device of the eighth invention further comprises a plurality of guide guides arranged at equal intervals in the arrangement direction below the spinning device and guiding the plurality of yarns spun from the spinning device individually, wherein the yarn path regulating guide is arranged below the plurality of guide guides and converges the plurality of yarns guided individually by the plurality of guide guides so that they are at equal intervals in the arrangement direction.

[0023] In the present invention, a plurality of yarns spun from a spinning device are arranged at equal intervals in the arrangement direction by being guided by a plurality of guide guides. And since the plurality of yarns guided by the plurality of guide guides head toward the suction port of the suction gun at the shortest distance, they are also at equal intervals on the yarn path regulating guide even during the operation of hanging the yarns on the yarn path regulating guide. For this reason, the operation of hanging the yarns can be easily performed with respect to the yarn path regulating guide. On the other hand, the plurality of yarns guided by the guide guide converge at the suction port, and the interval between the plurality of yarns becomes narrower from the upstream side to the downstream side in the yarn running direction. The yarn path regulating guide arranged in the region where the interval between adjacent yarns becomes narrower from the upstream side to the downstream side in the yarn running direction is more difficult to perform the operation of hanging the yarns than the yarn path regulating guide arranged in the region where the adjacent yarns run substantially parallel to each other. According to the present invention, even in a region where the operation of hanging the yarns has been difficult conventionally, the operation of hanging the yarns can be performed more easily by providing the positioning portion.

[0024] The spinning take-up device of the ninth invention is characterized in that, in the eighth invention, the positioning portion is movable in the vertical direction.

[0025] Generally, the vertical position of the guide guide in the spinning take-up device is appropriately adjusted according to the type of yarn spun from the spinning device and the like. When the vertical position of the guide guide changes, it is necessary to change the vertical position of the positioning portion that defines the predetermined position for positioning the suction port of the suction gun. According to the present invention, the vertical position of the positioning portion can be appropriately adjusted corresponding to the vertical position of the guide guide. Thereby, even if the position of the guide guide changes, the positioning portion can be arranged at an appropriate position, and the operation of hanging the yarns can be performed more easily with respect to the yarn path regulating guide.

[0026] The spinning take-up device of the tenth invention is characterized in that, in the first to ninth inventions, the positioning portion is inclined with respect to the horizontal plane.

[0027] According to the present invention, by arranging the suction gun from below so that the suction port faces obliquely upward with respect to the positioning portion inclined with respect to the horizontal plane, the suction gun can be supported from below along the inclination, making it easier to support a heavy suction gun. As a result, the threading operation can be performed more easily.

[0028] The spinning take-up device of the eleventh invention is characterized in that, in the first to tenth inventions, the positioning portion is movable in the arrangement direction.

[0029] According to the present invention, the position of the positioning portion in the arrangement direction can be adjusted as appropriate. For this reason, when viewed from the orthogonal direction, the position of the positioning portion can be adjusted so as to define a predetermined position determined such that a plurality of yarns sucked into the suction port of the suction gun positioned by the positioning portion and a plurality of groove portions overlap. As a result, the threading operation can be performed even more easily with respect to the yarn path regulating guide.

[0030] The spinning take-up device of the twelfth invention is characterized in that, in the first to eleventh inventions, the positioning portion has a V-shaped cross-sectional shape.

[0031] According to the present invention, by disposing the tip portion including the suction port of the suction gun at the portion having the V-shaped cross-sectional shape of the positioning portion, it is possible to suppress the tip portion including the suction port of the suction gun from moving during the threading operation. For this reason, the suction gun can be easily held continuously during the threading operation, and the threading operation can be performed more easily with respect to the yarn path regulating guide.

Effect of the Invention

[0032] By facilitating the threading operation, the threading operation time can be shortened and the amount of yarn to be discarded can also be reduced, so it is also possible to reduce the production cost.

[0034] (Overall configuration of spinning take-up device 1) Preferred embodiments of the present invention will be described below with reference to the drawings. Figure 1 is a diagram showing the schematic configuration of the spinning and drawing apparatus 1. Hereinafter, the vertical direction on the paper in Figure 1 will be referred to as the vertical direction, and the horizontal direction on the paper will be referred to as the horizontal direction. Also, the direction perpendicular to the paper in Figure 1 will be referred to as the front-to-back direction, and the front of the paper will be referred to as the front. Hereafter, the above directional terms will be used as appropriate in the explanation.

[0035] The spinning take-up device 1 is configured to wind up multiple yarns Y spun from the spinning device 2 using a yarn winding device 4. The spinning device 2 is a device that spins molten polymer downward as yarn Y. As shown in Figure 1, the spinning take-up device 1 includes multiple oil guides 5, each equipped with an oil nozzle, multiple guide guides 6, a yarn path restricting guide 7, a positioning unit 31, a yarn sway suppressing member 32, two godette rollers 11 and 12, a spinning and drawing device 3, and a yarn winding device 4. The spinning device 2, the multiple oil guides 5 and multiple guide guides 6 located below it are located on the upper floor (second floor). The yarn path restricting guide 7, the two godette rollers 11 and 12, the spinning and drawing device 3, and the yarn winding device 4 are located on the lower floor (first floor).

[0036] Multiple oil guides 5 are positioned below the spinning apparatus 2 and apply oil to each of the multiple yarns Y spun downward from the spinning apparatus 2. Multiple guide 6 are positioned at equal intervals in the left-right direction below each of the multiple oil guides 5 and individually guide the multiple yarns Y to which the oil has been applied.

[0037] The thread path regulating guide 7 is positioned below the multiple guide 6 and converges the multiple threads Y, which are individually guided by the multiple guide 6, so that they are at equal intervals in the left-right direction. The thread path regulating guide 7 has multiple grooves 71 (see Figure 4) arranged in an alignment direction perpendicular to the thread travel direction in which the multiple threads Y travel, i.e., in the left-right direction. The grooves 71 are open at the front. As the multiple threads Y each travel within the multiple grooves 71, the spacing in the left-right direction is determined, and the left-right movement of the multiple threads Y arranged in the left-right direction is restricted.

[0038] As shown in Figure 2, the yarn guide 7 is attached to the front side of the machine body 17 of the spinning take-up device 1 via a connecting member 18. A yarn restricting bar 72 is also attached to the yarn guide 7. As shown in Figure 2, the yarn restricting bar 72 guides multiple yarns Y into the yarn guide 7 when threading yarn onto the yarn guide 7, and prevents the multiple yarns Y from coming off the yarn guide 7 after threading. As shown in Figure 4, the yarn restricting bar 72 extends in the left-right direction across multiple grooves 71. At its left end, the yarn restricting bar 72 is cantilevered to the tip of a lever 73. The lever 73 is rotatable around an axis 74 that extends in the left-right direction. When threading yarn onto the yarn guide 7, the yarn restricting bar 72 is positioned in a restricting position in front of the multiple yarns Y, as shown in Figure 2. Furthermore, when the yarn Y is being wound by the yarn winding device 4, as shown in Figure 3, the yarn restriction bar 72 is positioned lower and further back than the position of the yarn restriction bar 72 in the restriction position, as the lever 73 rotates clockwise around the axis 74 when viewed from the left and right directions. When the yarn restriction bar 72 is in the release position, the yarn restriction bar 72 does not interfere with the yarn Y and does not restrict the introduction of the yarn Y into the groove 71 of the yarn path restriction guide 7.

[0039] The positioning unit 31 is located downstream of the thread guide 7 in the thread travel direction. Multiple threads Y are threaded onto the thread guide 7 by an operator while the threads Y are held in place by a suction gun 40 (see Figure 3). The positioning unit 31 positions the suction port 40a of the suction gun 40 at a position that allows threading onto the thread guide 7. The thread sway suppression member 32 is located between the thread guide 7 and the positioning unit 31 in the thread travel direction. The positioning unit 31 and the thread sway suppression member 32 will be described in detail later.

[0040] As shown in Figure 1, the godette rollers 11 and 12 are positioned downstream of the yarn path regulating guide 7 and the positioning unit 31 in the yarn travel direction, and are rotationally driven by a motor (not shown). Multiple yarns Y spun from the spinning device 2 are wound onto the godette roller 11 via the oil guide 5, guide guide 6, and yarn path regulating guide 7, and are sent by the godette roller 11 to the spinning and drawing device 3. Multiple yarns Y that have been heated and drawn by the spinning and drawing device 3 are wound onto the godette roller 12, and are sent by the godette roller 12 to the yarn winding device 4.

[0041] The spinning and drawing device 3 is a device for heating and drawing multiple yarns Y, and is located below the spinning device 2. The spinning and drawing device 3 has a heat-insulating box 20 and five godet rollers 91 to 95 housed inside the heat-insulating box 20. A yarn inlet 20a for introducing multiple yarns Y into the heat-insulating box 20 is formed at the lower part of the right side of the heat-insulating box 20, and a yarn outlet 20b for leading multiple yarns Y out of the heat-insulating box 20 is formed at the upper part of the right side of the heat-insulating box 20.

[0042] The three lower godet rollers 91-93 are preheating rollers for preheating multiple threads Y before stretching, while the two upper godet rollers 94 and 95 are tempering rollers for heat-setting the stretched threads Y. The roller surface temperature of the two upper godet rollers 94 and 95 is set higher than that of the three lower godet rollers 91-93. Also, the thread feeding speed of the two upper godet rollers 94 and 95 is faster than that of the three lower godet rollers 91-93.

[0043] Multiple threads Y introduced into the insulated box 20 via the thread inlet 20a are first preheated to a stretchable temperature while being fed by godet rollers 91-93. The preheated threads Y are then stretched by the difference in thread feeding speed between godet roller 93 and godet roller 94. Furthermore, the threads Y are heated to an even higher temperature while being fed by godet rollers 94 and 95, and the stretched state is heat-set. The stretched threads Y are then led out of the insulated box 20 via the thread outlet 20b.

[0044] The yarn winding device 4 is a device for winding multiple yarns Y and is located below the spinning and drawing device 3. The yarn winding device 4 includes a bobbin holder 13 and contact rollers 14, etc. The bobbin holder 13 has a cylindrical shape extending in the front-rear direction and is rotationally driven by a motor (not shown). Multiple bobbins B are mounted on the bobbin holder 13 in an orderly fashion along its axial direction. By rotating the bobbin holder 13, the yarn winding device 4 simultaneously winds multiple yarns Y onto multiple bobbins B, producing multiple packages P. The contact rollers 14 contact the surfaces of the multiple packages P, applying a predetermined contact pressure to shape the packages P.

[0045] (Positioning section 31) Next, the positioning section 31 will be described in detail. The positioning section 31 positions the suction port 40a of the suction gun 40 at a predetermined position downstream of the thread guide 7, where thread can be threaded onto the thread guide 7. The predetermined position is, as shown in Figure 4, a position determined such that, when viewed from the front-to-back direction (the direction orthogonal to the present invention), the multiple threads Y that are sucked into the suction port 40a of the suction gun 40 positioned at the positioning section 31 and the multiple grooves 71 overlap.

[0046] As shown in Figure 5, the positioning unit 31 is attached to the tip of the arm portion 51 which extends in the front-rear direction. The rear end of the arm portion 51 is rotatably cantilevered to the lifting plate 53 via a rotation axis 52 whose axis is oriented in the left-right direction. When threading the thread onto the thread guide 7, the arm portion 51 extends forward from the lifting plate 53, as shown in Figures 2 and 5. At this time, the positioning unit 31 attached to the tip of the arm portion 51 can position the suction port 40a of the suction gun 40 to the predetermined position described above. When the thread Y is being wound by the thread winding device 4, the arm portion 51 rotates around the rotation axis 52 so that its tip is facing downwards, as shown in Figure 3. At this time, the positioning unit 31 retracts from the thread paths of the multiple threads Y when the thread Y is being wound by the thread winding device 4.

[0047] The lifting plate 53 is fixed to the fixing plate 54 by a fixing member 55. More specifically, the fixing plate 54 has a lifting groove 57 that extends in the vertical direction. The lifting plate 53 is positioned behind the fixing plate 54, and the second lifting plate 56 is positioned in front of the fixing plate 54, so that the fixing plate 54 is sandwiched between the lifting plate 53 and the second lifting plate 56. The fixing member 55 penetrates the second lifting plate 56, the lifting groove 57, and the lifting plate 53 in the front-to-back direction, thereby fixing the lifting plate 53 to the fixing plate 54. The fixing member 55 is, for example, a screw. The fixing plate 54 is attached to the machine base body 17.

[0048] Furthermore, by loosening the fixing of the lifting plate 53 to the fixing plate 54 by the fixing member 55, the lifting plate 53 and the second lifting plate 56 can move vertically by moving the fixing member 55 up and down along the lifting groove 57. As the lifting plate 53 moves vertically, the arm portion 51 and the positioning portion 31 also move vertically. In other words, in this embodiment, the positioning portion 31 is movable vertically. By moving the positioning portion 31 vertically, when threading the thread onto the thread guide 7, the multiple grooves 71 on the thread guide 7 and the multiple threads Y can be aligned horizontally.

[0049] Furthermore, as shown in Figure 2, the positioning section 31 is configured to be inclined with respect to the horizontal plane when threading onto the thread guide 7. In detail, the positioning section 31 has a shape that extends in the front-rear direction, and is inclined so that its front end is located below its rear end. In this embodiment, when threading onto the thread guide 7, as shown in Figure 2, the suction gun 40 is positioned from below with the suction port 40a facing diagonally upward relative to the inclined positioning section 31. Furthermore, as shown in Figure 4, the positioning section 31 has a V-shaped cross-section when viewed from the front-rear direction. In this embodiment, when threading onto the thread guide 7, the tip portion of the suction gun 40, including the suction port 40a, is positioned on the V-shaped cross-sectional portion of the positioning section 31.

[0050] (Thread sway suppression member 32) Next, the yarn sway suppression member 32 will be described in detail. As shown in Figures 2 and 4, the yarn sway suppression member 32 is positioned between the yarn path regulating guide 7 and the positioning unit 31 in the yarn travel direction. Multiple yarns Y that are sucked into the suction port 40a of the suction gun 40 positioned in the positioning unit 31 come into contact with the yarn sway suppression member 32.

[0051] In this embodiment, the yarn sway suppression member 32 is attached to the rear part of the positioning unit 31 and moves integrally with the positioning unit 31. As described above, the positioning unit 31 can be moved away from the thread paths of the multiple threads Y when the yarn Y is being wound by the yarn winding device 4. Therefore, the yarn sway suppression member 32, which moves integrally with the positioning unit 31, can also be moved away from the thread paths of the multiple threads Y when the yarn Y is being wound by the yarn winding device 4, as shown in Figure 3. Furthermore, as described above, the positioning unit 31 is movable in the vertical direction. Therefore, the yarn sway suppression member 32, which moves integrally with the positioning unit 31, is also movable in the vertical direction.

[0052] The thread sway suppression member 32 has a cylindrical shape with its axis in the left-right direction. Multiple threads Y that are sucked into the suction port 40a of the suction gun 40 positioned in the positioning unit 31 come into contact with the circumferential surface of the thread sway suppression member 32.

[0053] Furthermore, as shown in Figure 2, when the suction port 40a of the suction gun 40 is positioned on the positioning unit 31, the angle θ on the side where the thread sway suppression member 32 is located is 165 degrees or less, when viewed from the left and right directions, and is the angle formed by the multiple threads Y running upstream of the thread sway suppression member 32 in the thread travel direction and the multiple threads Y running downstream of the thread sway suppression member 32 in the thread travel direction. In this embodiment, the angle on the side where the thread sway suppression member 32 is located when viewed from the left and right directions is the angle closer to the machine base body 17 in the front-rear direction, i.e., the rear angle, assuming that the multiple threads Y appear as one when viewed from the left and right directions, and is formed by the multiple threads Y running upstream of the thread sway suppression member 32 in the thread travel direction and the multiple threads Y running downstream of the thread sway suppression member 32 in the thread travel direction.

[0054] (Examples) Next, the average yarn threading time (seconds) on the yarn path regulating guide 7 of Comparative Example 1, Comparative Example 2, Comparative Example 3, and the Example were compared. For Comparative Examples 1 to 3, the average yarn threading time was measured when an operator performed yarn threading on the yarn path regulating guide 7 of a spinning take-up device 1 that did not have the positioning unit 31 and yarn sway suppression member 32 of the above embodiment. For the Example, the average yarn threading time was measured when an operator performed yarn threading on the yarn path regulating guide 7 of a spinning take-up device 1 that was similar to the above embodiment, i.e., a spinning take-up device 1 that had the positioning unit 31 and yarn sway suppression member 32.

[0055] Comparative Example 1 is the average threading time when a skilled threader performs the threading operation on the thread guide 7. Comparative Example 2 is the average threading time when an experienced threader with some experience in threading the thread guide 7 performs the threading operation. Comparative Example 3 is the average threading time when a novice with no experience in threading the thread guide 7 performs the threading operation. The Example shows the average threading time when an experienced threader and a novice perform the threading operation, respectively. A skilled threader is defined as someone who can perform threading and does so every day. An experienced threader is defined as someone who can perform threading but does not do so every day. A novice is defined as someone who has never performed threading operation before. In addition, the average threading time in Comparative Example 1 is the average of the threading times taken when one skilled threader A performed the threading operation 7 times. In Comparative Example 2, the average threading time is the average of the threading time taken by experienced person A when they performed the threading process twice, and the average of the threading time taken by experienced person B when they performed the threading process once. In Comparative Example 3, the average threading time is the average of the threading time taken by beginner person A when they performed the threading process twice, and the average of the threading time taken by beginner person B when they performed the threading process once. In the Example, the average threading time is the average of the threading time taken by experienced person A and beginner person A when they each performed the threading process twice.

[0056] As shown in Figure 6, the average threading time in Comparative Example 1 was 12 seconds, compared to 20 seconds in Comparative Example 2 and 56 seconds in Comparative Example 3. In other words, it was found that the less experience a person had with threading, the longer it took to thread the yarn onto the thread guide 7. On the other hand, the average threading time in the Example was 10 seconds. Therefore, it was found that the time required to thread the yarn onto the thread guide 7 was reduced regardless of the level of proficiency in threading.

[0057] (effect) The spinning take-up device 1 of this embodiment includes a yarn path regulating guide 7 having a plurality of grooves 71 arranged in the left-right direction, and a positioning unit 31 that positions the suction port 40a of the suction gun 40 at a predetermined position downstream of the yarn path regulating guide 7 in the yarn travel direction, where yarn can be threaded onto the yarn path regulating guide 7. According to this embodiment, when threading yarn onto the yarn path regulating guide 7, the suction port 40a of the suction gun 40 can be positioned by the positioning unit 31 at a predetermined position where yarn can be threaded onto the yarn path regulating guide 7. Therefore, it does not take time to position the suction port 40a of the suction gun 40 at the appropriate working position. Furthermore, since it is only necessary to hold the suction gun 40 while positioning the suction port 40a at the positioning unit 31, the difficulty of continuously holding the suction gun 40 during the threading operation is also eliminated. As a result, threading operations can be easily performed on the yarn path regulating guide 7.

[0058] Furthermore, in this embodiment, the predetermined position is determined such that, when viewed from the front-to-back direction, the multiple threads Y that are sucked into the suction port 40a of the suction gun 40 positioned on the positioning unit 31 and the multiple grooves 71 overlap. According to this embodiment, since the suction port 40a of the suction gun 40 is positioned by the positioning unit 31, when viewed from the front-to-back direction, the multiple threads Y that are sucked into the suction port 40a of the suction gun 40 positioned on the positioning unit 31 and the multiple grooves 71 overlap. As a result, when threading the thread onto the thread guide 7, it becomes unnecessary to adjust the left-to-right position of each of the multiple threads Y, making the threading operation on the thread guide 7 even easier.

[0059] Furthermore, in this embodiment, the spinning take-up device 1 has a yarn sway suppression member 32 positioned between the yarn path regulating guide 7 and the positioning unit 31 in the yarn travel direction, which comes into contact with the multiple yarns Y that are sucked into the suction port 40a positioned in the positioning unit 31. A swirling flow is generated inside the suction gun 40. If the yarn sway caused by the swirling flow is transmitted to the yarn Y traveling near the yarn path regulating guide 7 upstream of the positioning unit 31 in the yarn travel direction, it becomes difficult to thread the yarn onto the yarn path regulating guide 7. According to this embodiment, by positioning the yarn sway suppression member 32, which comes into contact with the multiple yarns Y, between the yarn path regulating guide 7 and the positioning unit 31, it is possible to suppress the transmission of yarn sway caused by the swirling flow generated inside the suction gun 40 to the multiple yarns Y traveling near the yarn path regulating guide 7. This makes it even easier to thread the yarn onto the yarn path regulating guide 7.

[0060] Furthermore, in this embodiment, when the suction port 40a of the suction gun 40 is positioned on the positioning unit 31, when viewed from the left and right directions, the angle θ on the side where the thread sway suppression member 32 is located is 165 degrees or less, between the multiple threads Y traveling upstream of the thread sway suppression member 32 in the thread travel direction and the multiple threads Y traveling downstream of the thread sway suppression member 32 in the thread travel direction. According to this embodiment, when viewed from the left and right directions, the thread sway suppression member 32 can be pressed more strongly against the multiple threads Y compared to the case where the angle θ is greater than 165 degrees. This makes it possible to more reliably suppress the transmission of thread sway caused by the swirling flow generated inside the suction gun 40 to the multiple threads Y traveling near the thread path regulating guide 7.

[0061] Furthermore, in this embodiment, the yarn sway suppression member 32 can be retracted from the yarn paths of multiple yarns Y when the yarn winding device 4 is winding the yarn Y. According to this embodiment, when the yarn winding device 4 is winding the yarn Y after the yarn threading operation on the yarn path regulating guide 7 is completed, the yarn sway suppression member 32 can avoid contact with the running yarn Y. This prevents the quality of the yarn Y from degrading due to contact with the yarn sway suppression member 32.

[0062] Furthermore, in this embodiment, the positioning unit 31 can be retracted from the thread paths of multiple threads Y when the thread winding device 4 is winding the threads Y. According to this embodiment, when the thread winding device 4 is winding the threads Y after the thread threading operation on the thread path regulating guide 7 is completed, the positioning unit 31 can avoid contact with the running threads Y. This prevents the quality of the threads Y from degrading due to contact with the positioning unit 31.

[0063] Furthermore, the spinning take-up device 1 of this embodiment further includes a plurality of guide guides 6 arranged at equal intervals in the left-right direction below the spinning device 2, which individually guide a plurality of yarns Y spun from the spinning device 2. The yarn path restricting guide 7 is positioned below the plurality of guide guides 6 and converges the plurality of yarns Y guided individually by the plurality of guide guides 6 so that they are at equal intervals in the left-right direction. In this embodiment, the plurality of yarns Y spun from the spinning device 2 are guided by the plurality of guide guides 6 and arranged at equal intervals in the left-right direction. The plurality of yarns Y guided by the plurality of guide guides 6 then move towards the suction port 40a of the suction gun 40 along the shortest distance, so they are also at equal intervals on the yarn path restricting guide 7 when the yarn is threaded onto the yarn path restricting guide 7. Therefore, the yarn threading operation on the yarn path restricting guide 7 can be easily performed. On the other hand, the plurality of yarns Y guided by the guide guides 6 converge at the suction port 40a, and the spacing between the plurality of yarns Y narrows as you move from the upstream side to the downstream side in the yarn travel direction. A thread guide 7 positioned in a region where the spacing between adjacent threads Y narrows as the thread travels from upstream to downstream is more difficult to thread than a thread guide 7 positioned in a region where adjacent threads Y travel approximately parallel to each other. According to this embodiment, even in regions where thread threading was previously difficult, the positioning unit 31 makes thread threading easier.

[0064] Furthermore, in this embodiment, the positioning unit 31 is movable in the vertical direction. Generally, the vertical position of the guide 6 in the spinning take-up device 1 is adjusted as appropriate depending on the type of yarn Y spun from the spinning device 2. When the vertical position of the guide 6 changes, it becomes necessary to change the vertical position of the positioning unit 31, which defines the predetermined position for positioning the suction port 40a of the suction gun 40. According to this embodiment, the vertical position of the positioning unit 31 can be adjusted as appropriate in accordance with the vertical position of the guide 6. As a result, even if the position of the guide 6 changes, the positioning unit 31 can be positioned in an appropriate location, making the yarn threading operation on the yarn path regulating guide 7 even easier.

[0065] Furthermore, in this embodiment, the positioning section 31 is inclined with respect to the horizontal plane. According to this embodiment, by positioning the suction gun 40 from below with respect to the positioning section 31 which is inclined with respect to the horizontal plane, the suction port 40a faces diagonally upward, the suction gun 40 can be supported from below along the inclination, making it easier to support the heavy suction gun 40. This makes the threading work easier.

[0066] Furthermore, in this embodiment, the positioning section 31 has a V-shaped cross-section. According to this embodiment, by positioning the tip portion of the suction gun 40, including the suction port 40a, on the V-shaped cross-section portion of the positioning section 31, it is possible to suppress the movement of the tip portion of the suction gun 40, including the suction port 40a, during threading. Therefore, the suction gun 40 can be easily held during threading, and threading can be performed more easily against the thread guide 7.

[0067] (modified version) The following describes modified versions of the above embodiment. However, components having the same configuration as the above embodiment are denoted by the same reference numerals and their descriptions are omitted as appropriate.

[0068] (First variation) In the above embodiment, the positioning unit 31 can be moved away from the thread paths of the multiple threads Y when the thread winding device 4 is winding the threads Y. However, the positioning unit 31 may be positioned in a location that does not overlap with the thread paths of the multiple threads Y when the thread winding device 4 is winding the threads Y. For example, in the first modified example shown in Figures 7 to 9, the positioning unit 131 is attached to the lifting plate 153 and is positioned in a location that does not overlap with the thread paths of the multiple threads Y when the thread winding device 4 is winding the threads Y.

[0069] As shown in Figure 9, the lifting plate 153 is fixed to the fixing plate 154 by a fixing member 155. More specifically, as shown in Figure 9, the fixing plate 154 has a lifting groove 157 that extends in the vertical direction. The lifting plate 153 is positioned behind the fixing plate 154, and the second lifting plate 156 is positioned in front of the fixing plate 154, so that the fixing plate 154 is sandwiched between the lifting plate 153 and the second lifting plate 156. The fixing member 155 penetrates the second lifting plate 156, the lifting groove 157, and the lifting plate 153 in the front-to-back direction, thereby fixing the lifting plate 153 to the fixing plate 154. The fixing member 155 is, for example, a screw. The fixing plate 154 is attached to the machine base body 17.

[0070] Furthermore, by loosening the fixing of the lifting plate 153 to the fixing plate 154 by the fixing member 155, the lifting plate 153 and the second lifting plate 156 can move vertically by moving the fixing member 155 up and down along the lifting groove 157. As the lifting plate 153 moves vertically, the positioning part 131 also moves vertically. That is, in the first modified example, the positioning part 131 is movable vertically. By moving the positioning part 131 vertically, when threading the thread onto the thread guide 7, the multiple grooves 71 on the thread guide 7 and the multiple threads Y can be aligned horizontally. Note that in the first modified example, even when the positioning part 131 moves vertically, it takes a position that does not overlap with the thread paths of the multiple threads Y when the thread winding device 4 winds the threads Y.

[0071] Furthermore, as shown in Figure 7, the positioning section 131 is configured to be inclined with respect to the horizontal plane when threading onto the thread guide 7. In the first modified example, when threading onto the thread guide 7, as shown in Figure 7, the suction gun 40 is positioned from below with the suction port 40a facing diagonally upward relative to the positioning section 131, which is inclined with respect to the horizontal plane. Furthermore, as shown in Figure 9, the positioning section 131 has a V-shaped cross-section when viewed from the front or back. In the first modified example, when threading onto the thread guide 7, the tip portion of the suction gun 40, including the suction port 40a, is positioned on the V-shaped cross-sectional portion of the positioning section 131.

[0072] Furthermore, in the above embodiment, the yarn sway suppression member 32 is cylindrical in shape, but in the first modified example, the yarn sway suppression member 132 is a plate-shaped member. The plate-shaped member is processed and treated in a way that prevents yarn breakage from occurring due to contact with the multiple yarns Y at the contact portion with the multiple yarns Y. The rear end portion of the yarn sway suppression member 132 is rotatably cantilevered to the fixing plate 154 via a rotation axis 141 with the left-right direction as the axial direction. When threading the yarn onto the yarn path regulating guide 7, the yarn sway suppression member 132 extends forward from the fixing plate 154, as shown in Figure 7. At this time, the multiple yarns Y that are sucked into the suction port 40a of the suction gun 40 positioned on the positioning portion 131 come into contact with the front surface of the yarn sway suppression member 132. When the yarn Y is wound by the yarn winding device 4, the yarn sway suppression member 132 rotates around the rotation axis 141 so that its tip is downward, as shown in Figure 8. At this time, the yarn sway suppression member 132 moves out of the way of the multiple yarns Y when the yarn Y is being wound by the yarn winding device 4.

[0073] Furthermore, as shown in Figure 7, when the suction port 40a of the suction gun 40 is positioned on the positioning unit 131, the angle θ' on the side where the thread sway suppression member 132 is located is 165 degrees or less, when viewed from the left and right directions, and is the angle formed by the multiple threads Y running upstream of the thread sway suppression member 132 in the thread running direction and the multiple threads Y running downstream of the thread sway suppression member 132 in the thread running direction. In the first modified example, the angle on the side where the thread sway suppression member 132 is located when viewed from the left and right directions is the angle closer to the machine base body 17, i.e., the rear angle, when it is assumed that the multiple threads Y appear as one when viewed from the left and right directions.

[0074] In the above embodiment, the thread sway suppression member 32 moves integrally with the positioning unit 31, but in the first modified example, the thread sway suppression member 132 does not move integrally with the positioning unit 131. Therefore, the positioning unit 131 is movable in the vertical direction, but the thread sway suppression member 132 does not move in the vertical direction.

[0075] In the first modified example, the positioning unit 131 is positioned so as not to overlap with the thread paths of multiple threads Y when the thread winding device 4 is winding the thread Y. Furthermore, the thread sway suppression member 132 can be retracted from the thread paths of multiple threads Y when the thread winding device 4 is winding the thread Y. This makes it possible to avoid contact between the positioning unit 131 and the thread sway suppression member 132 and the running thread Y when the thread winding device 4 is winding the thread Y after the thread threading operation on the thread path regulating guide 7 is completed. This prevents the quality of the thread Y from degrading due to contact with the positioning unit 131 and the thread sway suppression member 132.

[0076] Furthermore, both the positioning unit 131 and the yarn sway suppression member 132 may be positioned in a location that does not overlap with the yarn paths of multiple yarns Y when the yarn Y is being wound by the yarn winding device 4.

[0077] (Second variation) Next, a second modified example will be described with reference to Figure 10. In the second modified example, the positioning portion 231 is fixed to the lifting plate 253 by two fixing members 262. More specifically, as shown in Figure 10, the lifting plate 253 has an inclined portion 253a that is inclined to be positioned upward as it moves forward, and left and right grooves 254 extending along the left and right direction are formed in the inclined portion 253a. The positioning portion 231 is fixed to the inclined portion 253a of the lifting plate 253 by the two fixing members 262 passing through the positioning portion 231 and the left and right grooves 254 in a direction perpendicular to the inclined portion 253a. The fixing members 262 are, for example, screws.

[0078] Furthermore, by loosening the fixing of the positioning section 231 to the lifting plate 253 by the fixing member 262 and moving the fixing member 262 along the left and right grooves 254, the positioning section 231 can be moved in the left and right directions (see the solid double arrows in Figure 10).

[0079] In the second modification, the positioning portion 231 has a V-shaped cross-section, and the inner surface of the V-shaped portion of the positioning portion 231 fixed to the inclined portion 253a is inclined with respect to the horizontal plane. In the second modification, when threading the thread onto the thread guide 7, the suction gun 40 is positioned from below so that the suction port 40a faces diagonally upward relative to the positioning portion 231 which is inclined with respect to the horizontal plane.

[0080] Furthermore, the lifting plate 253 is fixed to the fixing plate 255 by a fixing member 257. More specifically, as shown in Figure 10, the fixing plate 255 has a lifting groove 256 that extends in the vertical direction. The fixing member 257 penetrates the lifting plate 253 and the lifting groove 256 in the front-rear direction, thereby fixing the lifting plate 253 to the fixing plate 255. The fixing member 257 is, for example, a screw. The fixing plate 255 is attached to the machine base body 17.

[0081] Furthermore, by loosening the fixing of the lifting plate 253 to the fixing plate 255 by the fixing member 257, the lifting plate 253 can be moved vertically by moving the fixing member 257 up and down along the lifting groove 256. As the lifting plate 253 moves vertically, the positioning part 231 also moves vertically. In other words, in the second modified example, the positioning part 231 is movable vertically. Note that in the second modified example, even when the positioning part 231 moves vertically, it is positioned so as not to overlap with the thread paths of multiple threads Y when the thread winding device 4 winds the thread Y.

[0082] In the second modified example, the yarn sway suppression member 232 is a plate-shaped member. The plate-shaped member is processed and treated in a way that prevents yarn breakage from occurring due to contact with the multiple yarns Y at the contact point with the multiple yarns Y. The rear end portion of the yarn sway suppression member 232 is cantilevered to the upper end portion of the lifting plate 253 via a rotation axis 241 whose axis is oriented in the left-right direction. When threading yarn onto the yarn path regulating guide 7, the yarn sway suppression member 232 extends forward from the lifting plate 253, as shown in Figure 10. At this time, the multiple yarns Y that are sucked into the suction port 40a of the suction gun 40 positioned on the positioning unit 231 come into contact with the front surface of the yarn sway suppression member 232. When the yarn Y is wound by the yarn winding device 4, the yarn sway suppression member 232 rotates around the rotation axis 241 so that its tip is downward (see the solid arrow in Figure 10). At this time, the yarn sway suppression member 232 moves out of the way of the multiple yarns Y when the yarn Y is being wound by the yarn winding device 4.

[0083] Furthermore, the thread sway suppression member 232 is movable in the vertical direction as the lifting plate 253 moves vertically.

[0084] In the second modified example, the positioning unit 231 is movable in the left-right direction. This allows the left-right position of the positioning unit 231 to be adjusted as appropriate. Therefore, the position of the positioning unit 231 can be adjusted so that, when viewed from the front-rear direction, a predetermined position can be defined in which the multiple threads Y that are sucked into the suction port 40a of the suction gun 40 positioned on the positioning unit 231 and the multiple grooves 71 overlap. This makes the threading operation on the thread guide 7 even easier.

[0085] In the second modified example, both the positioning unit 231 and the yarn sway suppression member 232 may be positioned in a location that does not overlap with the thread paths of the multiple yarns Y when the yarn Y is being wound by the yarn winding device 4, and may be retractable from the thread paths of the multiple yarns Y when the yarn Y is being wound by the yarn winding device 4.

[0086] (Other variations) The spinning take-up device 1 of the present invention does not necessarily include a yarn sway suppression member 32. Furthermore, the yarn path regulating guide 7 of the present invention does not necessarily have to be a guide that converges multiple yarns Y that are individually guided by multiple guide guides 6. For example, the yarn path regulating guide 7 may be a guide positioned between two rollers (e.g., godet rollers) where adjacent yarns Y are running substantially parallel to each other.

[0087] Furthermore, the positioning portion of the present invention does not need to be inclined with respect to the horizontal plane, nor does it need to have a V-shaped cross-section. For example, the positioning portion may have a U-shaped cross-section or a U-shaped cross-section.

[0088] The thread guide 7 in the above embodiment has a groove 71 that opens to the front, and converges multiple threads Y running in front of the thread guide 7 so that they are equally spaced in the left-right direction. However, the thread guide 7 is not limited to this form. For example, as shown in Figure 11, the thread guide 107 may have a groove that opens to the rear, and converge multiple threads Y running in rear of the thread guide 107 so that they are equally spaced in the left-right direction. The thread guide 107 is attached to the front of the machine base body 17 via a connecting member 118 that extends in the front-rear direction to the right (towards the back of the page) of the multiple threads Y arranged in the left-right direction. In this case, as shown in Figure 11, when the suction port 40a of the suction gun 40 is positioned on the positioning unit 31, it is preferable that the angle θ'' on the side where the thread sway suppression member 32 is located, when viewed from the left and right directions, is 165 degrees or less, and is formed by the multiple threads Y running upstream of the thread sway suppression member 32 in the thread running direction and the multiple threads Y running downstream of the thread sway suppression member 32 in the thread running direction. The angle on the side where the thread sway suppression member 32 is located when viewed from the left and right directions is the angle closer to the machine base body 17, i.e., the rear angle, when it is assumed that the multiple threads Y appear as one when viewed from the left and right directions. The thread guide 107 may also be attached to the front of the machine base body 17 via a connecting member 118 that extends in the front-to-back direction, to the left of the multiple threads Y arranged in the left-to-right direction (towards the front of the page).

[0089] Furthermore, in the present invention, the thread guide 7 and the connecting member 18 may be integrated, and the thread guide 107 and the connecting member 118 may be integrated. [Explanation of symbols]
