  Next, an embodiment of the present invention will be described. FIG. 1 is a front view of a spinning winder. In the following description, as shown in FIG. 1, the front end side of the bobbin holder 7 described later is described as the front side on which the operator operates the spinning winder. As shown in FIG. 1, a spinning winder 1 is arranged in a direction orthogonal to the plane of FIG. 1 (horizontal direction as viewed from the front) in FIG. The yarn 10 is sent to the lower winding unit 3 by the two godet rollers 11 and 12, and taken up by the winding unit 3.

  First, the winding unit 3 will be described. The winding unit 3 is disposed below the spinning machine 2, and a plurality of yarns 10 supplied from the spinning machine 2 via two godet rollers 11 and 12 are wound around a plurality of bobbins B, respectively. A package P is formed.

At this time, the yarn 10 wound around the bobbin B is traversed in the axial direction of the bobbin B by a traverse guide 8 that can reciprocate in the axial direction of the bobbin B immediately before the bobbin B in the axial direction of the bobbin B. P is formed. Further, the contact roller 9 rotates while applying a predetermined contact pressure to the package P when winding the yarn around the bobbin B, thereby adjusting the shape of the package P.

  FIG. 2 is a perspective view of the godet roller and the fulcrum guide. As shown in FIG. 1, the take-up winder 1 takes up a frame-like frame 14 arranged in the depth direction in FIG. 1 from the take-up unit 3 and a plurality of yarns 10 supplied from the spinning machine 2. The two godet rollers 11 and 12 and the plurality of yarns 10 wound around the godet roller 12 on the downstream side are respectively distributed to the plurality of bobbins B mounted on the bobbin holder 7 of the winding unit 3 and are traversed by the traverse guide 8. A plurality of fulcrum guides 13a to 13d (distribution guides) serving as fulcrums during swinging, and a yarn hooking guide 20 (thread holding member) for threading the plurality of yarns 10 sent from the godet roller 12 onto the plurality of fulcrum guides 13a to 13d. ) Etc.

  As shown in FIGS. 1 and 2, the two godet rollers 11, 12 are arranged above the body frame 5 of the winding unit 3 so that the shaft cores 11 a, 12 a are orthogonal to the shaft core 7 a of the bobbin holder 7. A driving roller that is rotatably supported by the motor and is driven by a driving motor (not shown). The godet roller 11 is disposed immediately below the spinning machine 2, and the godet roller 12 is disposed on the upper rear side of the godet roller 11.

  The godet roller 12 is moved by a lifting mechanism 16 (see FIG. 1) such as a linear motor, for example, at a yarn winding position (shown by a solid line in FIGS. 1 and 2) located substantially above the center in the arrangement direction of the fulcrum guides 13a to 13d. And a yarn hooking position (a position indicated by a two-dot chain line in FIGS. 1 and 2) that is lower than the yarn winding position and close to the yarn hooking guide 20 located at the end of the plurality of fulcrum guides 13. It is movable.

  The plurality of fulcrum guides 13 a to 13 d are below the downstream godet roller 12 at the yarn winding position and above the plurality of traverse guides 8. The plurality of bobbins mounted on the plurality of traverse guides 8 and the bobbin holder 7. Directly above B, the bobbin holders 7 are arranged side by side along the axis 7a of the bobbin holder 7 at the same interval as the intervals between the plurality of bobbin holders 7.

  As shown in FIG. 3, the fulcrum guide 13 is fixedly supported by a support plate 15 installed in the frame 14, and an insertion slit 40 and a guide hole 41 are formed. The fulcrum guide 13 can hang the thread 10 sucked by a suction pipe (not shown) from behind to the guide hole 41 through the insertion slit 40.

  As shown in FIG. 1 and FIG. 2, the plurality of yarns 10 supplied from the spinning machine 2 are unloaded and first wound side by side along the shaft core 11 a of the godet roller 11. Thereafter, the plurality of yarns 10 wound around the godet roller 11 are wound around the godet roller 12 at the yarn winding position while running in parallel obliquely upward. Then, the plurality of yarns 10 wound around the godet roller 12 are respectively wound around the plurality of fulcrum guides 13 a to 13 d and conveyed to the lower winding unit 3. Since the godet roller 12 is arranged not on the side of the arrangement direction of the plurality of fulcrum guides 13a to 13d but on the upper side, the bending angle of the yarn 10 at the fulcrum guide 13 is reduced, and the traveling speed of the yarn 10 is increased. It becomes possible to make it.

  The yarn hooking guide 20 has a columnar shape extending in a direction orthogonal to the direction in which the plurality of fulcrum guides 13a to 13d are arranged, and the peripheral surface thereof extends in accordance with the number of the plurality of fulcrum guides 13a to 13d. A plurality of grooves 20a formed at equal intervals in the existing direction and formed over the entire circumference are provided. The yarn hooking guide 20 is connected to the bar 23. The bar 23 can advance and retreat in a direction perpendicular to the direction in which the plurality of fulcrum guides 13 a to 13 d are orthogonal to the slide member 21 that is slidable in the direction in which the plurality of fulcrum guides 13 a to 13 d are arranged. Along with the movement, the yarn hooking guide 20 is also moved in a direction perpendicular to the arrangement direction of the plurality of fulcrum guides 13a to 13d.

  An example of the advance / retreat mechanism of the thread hook guide 20 is shown in FIG. The bar 23 is biased by a spring 32, and the base end side is connected to a cam follower 31 that can move in the cam groove 30. The cam groove 30 is formed in a closed loop shape by a linear portion along the arrangement direction of the plurality of fulcrum guides 13a to 13d and an inclined portion inclined with respect to the linear portion. The cam follower 31 is guided along the cam groove 30 by a motor (not shown), so that the yarn hooking guide 20 has a plurality of fulcrum guides parallel to the arrangement direction of the fulcrum guides 13 a to 13 d and the support plate 15. Move diagonally across 13a-13d.

  Here, the yarn hooking operation to the plurality of fulcrum guides 13a to 13d will be described. FIG. 4 is a diagram for explaining the movement locus of the yarn hooking guide during yarn hooking, and is a schematic plan view of the yarn hooking guide and the fulcrum guide as viewed from above. 5 and 6 are diagrams for explaining the yarn hooking operation by the yarn hooking guide. In FIG. 4, the yarn hooking guide 20, the slide member 21, and the bar 23 are moved in the order of (1) to (6), and the movement trajectory is illustrated every predetermined time, which is the origin position. The position (1) is indicated by a solid line, and the positions moved in the order of (2) to (6) are indicated by a one-dot chain line.

  Since the plurality of yarns 10 wound around the godet roller 12 are arranged in a direction orthogonal to the direction in which the plurality of fulcrum guides 13a to 13d are arranged, the plurality of yarns 10 wound around the godet roller 12 around the plurality of fulcrum guides 13 are arranged. When threading, it is necessary to change the interval between the plurality of yarns 10 and the direction in which the plurality of yarns 10 are arranged.

  First, as shown in FIG. 5 (a), the yarn hooking guide 20 is moved to the origin position (position (1) in FIG. 4) in front of the fulcrum guide 13d at the foremost end, and the godet roller 12 is moved to the yarn hooking position. . Then, the plurality of yarns 10 sent from the godet roller 12 are sucked and captured by the suction pipe 25.

  5B, the operator separates the plurality of yarns 10 into the respective grooves 20a of the yarn hooking guide 20 by operating the suction pipe 25 while keeping the yarn hooking guide 20 at the origin position. Then hang it. At this time, by moving the godet roller 12 to a yarn hooking position closer to the yarn hooking guide 20 than to the yarn winding position, a plurality of yarns 10 can be hooked on the yarn hooking guide 20 at a position close to the godet roller 12. The posture of the thread 10 to be rotated is more stable than the position far from the godet roller 12, and threading becomes easy.

  Thereafter, as shown in FIG. 5C, the godet roller 12 is moved from the yarn hooking position to the yarn winding position while the yarn hooking guide 20 remains at the origin position. Then, as shown in FIG. 5D, the yarn hooking guide 20 is moved along the guide rail 22 to the rearmost position (position (2) in FIG. 4) further rearward than the rearmost fulcrum guide 13a. (See FIG. 4). Then, the plurality of yarns 10 hung on the yarn hooking guide 20 are moved further rearward than the fulcrum guide 13a at the rearmost end.

  Then, the yarn hooking guide 20 is moved along the arrangement direction of the plurality of fulcrum guides 13a to 13d while the bar 23 is retracted, and the yarn 10 is hung on the plurality of fulcrum guides 13a to 13d. As shown in FIG. 4, the yarn hooking guide 20 is moved from the rear of the fulcrum guide 13a to the front of the fulcrum guide 13d along the inclination direction inclined by the angle θ with respect to the arrangement direction of the plurality of fulcrum guides 13a to 13d. . This angle θ is determined from the interval l1 between the plurality of fulcrum guides 13a to 13d and the interval l2 between the plurality of grooves 20a of the yarn hooking guide 20.

  As shown in FIG. 5 (a), the yarn hooking guide 20 is set to the rearmost position in FIG. 4 (2), and the plurality of yarns 10 are moved further rearward than the fulcrum guide 13a at the rearmost end. The hanging guide 20 is moved along the tilt direction (direction B in FIG. 4).

  Then, first, when the yarn hooking guide 20 moves to the position (3) in FIG. 4, the fulcrum guide 13a at the rearmost side and the yarn 10a at the proximal end side of the yarn hooking guide 20 cross each other, As shown in FIG. 6B, the thread 10a is hung on the fulcrum guide 13a. Further, when the yarn hooking guide 20 is continuously moved along the above inclination direction, the yarn hooking guide 20 is moved in the order of (3) → (4) → (5) in FIG. 4, and FIG. 6 (c). As shown in FIG. 2, the yarn is hooked on the fulcrum guides 13a to 13d in order from the base end side yarn 10a hung on the yarn hooking guide 20.

  Thereafter, as shown in FIG. 6D, when the yarn hooking guide 20 is moved further forward than the foremost fulcrum guide 13d, all the yarns 10a to 10d hung on the yarn hooking guide 20 are all in turn. It is hung on the fulcrum guides 13a to 13d. The yarn hooking guide 20 that has finished threading to all the fulcrum guides 13a to 13d is located at the origin position ahead of the plurality of fulcrum guides 13a to 13d that does not hinder the traveling of the plurality of yarns 10 when winding the yarn. Evacuated.

  According to the yarn winding machine 1 in the present embodiment, the yarn hooking guide 20 holding the plurality of yarns 10 without moving the godet roller 12 and the plurality of fulcrum guides 13a to 13d is replaced with the plurality of fulcrum guides 13a to 13d and the bobbin holder. 7 is moved in the direction in which the plurality of fulcrum guides 13a to 13d are arranged, so that the plurality of yarns 10 can be conveyed to the corresponding fulcrum guides 13, respectively.

  The arrangement direction of the plurality of yarns 10 held by the yarn hooking guide 20 and the arrangement direction of the plurality of fulcrum guides 13a to 13d are orthogonal to each other, and each fulcrum guide 13 can be threaded from the rear. Since the thread 10 enters the groove 20a of the guide 20 from the same direction as the thread hook of the fulcrum guide 13, the thread hook guide 20 is held by the thread hook guide 20 by moving the thread hook guide 20 from the rear to the front in the above inclination direction. Further, the plurality of yarns 10 can be transferred to the plurality of fulcrum guides 13 in order from one side and threaded without interfering with the support plate 15.

  In this way, the yarn hooking guide 20 can be reduced in size because it only moves while holding the plurality of yarns 10, and the structure of the device including the yarn hooking guide 20 and its moving mechanism can be simplified. Can reduce failures and reduce manufacturing costs. The yarn hooking guide 20 is retracted because it is not used when winding the yarn onto the bobbin B. However, since the size thereof is small, the retracting area can be reduced, and the fulcrum guides 13a to 13d and the bobbin holder 7 are also retracted. Therefore, it is not necessary to newly secure a moving area of the yarn hooking guide 20, and the degree of freedom in installation can be increased.

  Next, modified embodiments in which various modifications are made to the above-described embodiment will be described. However, those having the same configuration as that of the above-described embodiment are denoted by the same reference numerals and description thereof is omitted as appropriate.

  In the present embodiment, after the yarn hooking guide 20 moves in the A direction along the direction in which the plurality of fulcrum guides 13a to 13d are arranged, the plurality of yarns 10 are moved rearward from the rearmost fulcrum guide 13a. The yarn hooking guide 20 is moved in the tilt direction (B direction) and threaded around the plurality of fulcrum guides 13a to 13d. It may be configured to only move in the arrangement direction. Even in this case, by moving the yarn hooking guide 20, the plurality of yarns 10 held by the yarn hooking guide 20 can be respectively carried to corresponding positions of the plurality of fulcrum guides 13a to 13d. If the thread 10 can be carried to the position of the corresponding fulcrum guide 13, threading by the operator becomes very easy.

  In the present embodiment, the godet roller 12 is disposed above the plurality of fulcrum guides 13a to 13d at the yarn winding position, but is disposed further forward or rearward in the arrangement direction of the plurality of fulcrum guides 13a to 13d. It may be.

  Further, in the present embodiment, the shaft core 12a of the godet roller 12 is orthogonal to the shaft core 7a of the bobbin holder 7, but may not be orthogonal, may intersect, or may be parallel. Good.

  In the present embodiment, the fulcrum guide 13 functions as a distribution guide that distributes the plurality of yarns 10 to the plurality of bobbins B in addition to the function as a guide serving as a fulcrum for traversing during traverse. The traversing fulcrum guide and the distribution guide may be provided separately.
