Touching. The biasing portion 32 is biased inward in the axial direction by a spring or the like (not shown), whereby the second winding tube 19A and the winding body 40 held by the cradle 20 are axially moved by the biasing portion 32. It is biased toward the inside.

Further, as shown in FIG. 5, the urging portion 32 has a notch 33 extending radially inward from the outer peripheral end thereof and penetrating the urging portion 32 in the axial direction of the bobbin holders 22a and 22b. Is formed. In addition, in order to make drawing easy to understand, in FIG. 5, the surface of the urging portion 32 on the insertion portion 31 side is hatched, and the position of the first winding tube 19B is indicated by a two-dot chain line.

  The cradle 20 is provided with a rotation speed sensor 35 for measuring the rotation speed of the bobbin holder 22b (or 22a). The rotation speed sensor 35 measures the rotation speed of the bobbin holder 22b so that the winding is performed. The number of rotations of the tubes 19A and 19B is measured.

Next, the winding body 40 will be described. The winding body 40 includes two first winding tubes 19B whose length in the axial direction is about half of the second winding tube 19A, and a connecting member 41 that connects the first winding tube 19B in a separable manner. ing.

As shown in FIGS. 6 and 7, the connecting member 41 is a substantially cylindrical member made of an elastic material such as synthetic resin and having an outer diameter substantially the same as the inner diameter of the first winding tube 19B. The portions located on both sides of the central portion of the connecting member 41 with respect to the axial direction are respectively inserted portions 42. In the connecting member 41, these two inserted portions 42 are respectively arranged from the tip side thereof . by inserting one winding tube 19B, the first take up tube 19B attached to the connecting member 41, thereby linking the two first take up tube 19B to each other.

Further, the length of the insertion portion 42 in the axial direction is shorter than that of the first winding tube 19B, and in the winding body 40, the first winding tube 19B is more outward in the axial direction than the connecting member 41. Jumping out. Thus, as described above, the insertion portion 31 of the bobbin holders 22a and 22b can be inserted through the portion of the first winding tube 19B that protrudes outward in the axial direction from the connecting member 41. .

  In addition, a protruding portion 44 is provided at the distal end portion of each insertion portion 42 so as to extend over the entire circumference of the outer peripheral surface and protrude radially outward from the other portions. In addition, a plurality of protrusions 45 arranged at substantially equal intervals in the circumferential direction are provided on the outer peripheral surface of the end of each insertion portion 42 opposite to the tip.

Thus, when the insertion portion 42 is inserted through the first winding tube 19B, the protrusion 44 and the plurality of protrusions 45 are brought into close contact with the inner peripheral surface of the first winding tube 19B due to the elasticity of the insertion portion 42, thereby The first winding tube 19B is fixed to the insertion portion 42.

Each insertion portion 42 is formed with a plurality of slits 46. The plurality of slits 46 are arranged along the circumferential direction of the connecting member 41, and each of the slits 46 extends along the axial direction of the connecting member 41 and opens at the tip of the insertion portion 42. Thus, the insertion portion 42 is inserted through the first winding tube 19B, when a force directed inward from radially outward from the first take up tube 19B is applied, its diameter is reduced, the the insertion portion 42 When the one take-up tube 19B is removed, the diameter returns to the original due to elasticity. That is, the diameter of the insertion part 42 can be expanded or reduced.

An O-ring 43 (annular member) made of an elastic material such as rubber is wound around a substantially central portion in the axial direction of the connecting member 41 located between the two insertion portions 42. In a state where the first winding tube 19B is attached to the insertion portion 42, the O-ring 43 and the inner end in the axial direction of the first winding tube 19B are in close contact with each other.

The traverse device 21 includes a belt body 26 that reciprocates by a motor (not shown), and two traverse guides 27a and 27b that are provided on the belt body 26 and guide yarns Ya and Yb. The belt body 26 is, for example, a toothed belt having a large number of teeth on the inner periphery, and is wound around a drive pulley 28 and a pair of driven pulleys 29 that are rotated forward and backward by a drive motor (not shown). The travel path of the belt body 26 between the pair of driven pulleys 29 is substantially parallel to the axis of the first winding tube 19B. The traverse guides 27 a and 27 b are provided on the belt body 26 with a predetermined interval between one and the other of the driven pulleys 29. In this embodiment, the “predetermined interval” is substantially the same interval as the distance between the centers of the two first winding tubes 19B in the axial direction. The two traverse guides 27a and 27b are detachable from the belt body 26, respectively.

  Further, on the upstream side of the traverse device 21, a yarn guide 30a for changing the yarn path of the yarn Ya sent from the third feed roller 9 to the front of the traverse center of the traverse guide 27a, and the third feed roller 9 Is provided with a yarn guide 30b for changing the yarn path of the yarn Yb fed from the front to the front of the traverse center of the traverse guide 27b. Further, a thread guide 30c is provided between the thread guides 30a and 30b. As shown in FIGS. 2 and 3, the yarn guide 30 c is arranged with respect to a direction (vertical direction in FIGS. 2 and 3) perpendicular to the central axis of the winding tubes 19 A and 19 B attached to the cradle 20. It is arranged at a position farther from the traverse guides 27a and 27b than 30b. Note that the yarn guides 30a to 30c may be configured so that they can be attached, removed, or changed in position according to the usage situation.

  The winding drum 23 is disposed so as to be in close contact with the outer peripheral surfaces of the winding tubes 19A and 19B held by the cradle 20. When the winding drum 23 is rotated by a motor (not shown), the winding tubes 19A and 19B that are in close contact with the winding drum 23 are rotated.

Next, a procedure for forming the package P in the false twisting weight 100 will be described. In the false twisting weight 100, two yarns Ya and Yb are wound around two first winding tubes 19B to form two packages P, and two yarns Ya and Yb are combined. Then, it is possible to switch between winding the combined yarn Yg around one second winding tube 19A and forming one package P.

  First, an operation for forming a plurality of packages P will be described. In this case, the two yarns Ya and Yb sent from the yarn supply packages 11a and 11b are respectively supplied to the pipes 12a and 12b, the first feed roller 6, the primary heater 13, and the cooling devices 14a and 14b. A false twisting device 15a, 15b, an upstream second feed roller 7, an interlace nozzle 16a, 16b, a downstream second feed roller 8, a secondary heater 17, and a third feed roller 9. To the winding device 18.

  More specifically, the yarn feed speed of the upstream second feed roller 7 is set to be larger than the yarn feed speed of the first feed roller 6. As a result, the yarns Ya and Yb are stretched between the first feed roller 6 and the upstream second feed roller 7, and in this state, the first feed roller 6 and the upstream first Twist between the two feed rollers 7. The yarns Ya and Yb twisted while being stretched are heat-set by the primary heater 13 and then cooled by the cooling devices 14a and 14b. The twisted and heat-set and cooled yarns Ya and Yb are untwisted after passing through the false twisting devices 15a and 15b until reaching the upstream second feed roller 7.

  The yarns Ya and Yb that have passed through the upstream second feed roller 7 are respectively guided to the interlace nozzles 16a and 16b, and after the interlaced portions are formed by the interlace nozzles 16a and 16b, the second downstream side It is sent to the feed roller 8.

  Usually, the yarn feeding speed of the downstream second feed roller 8 is set to a speed different from the yarn feeding speed of the third feed roller 9. As a result, the yarns Ya and Yb are relaxed between the second feed roller 8 and the third feed roller 9 on the downstream side, and in this state, the yarns Ya and Yb are subjected to relaxation heat treatment in the secondary heater 17, and the third It is sent to the feed roller 9. The ratio of the yarn feed speed of the downstream second feed roller 8 and the yarn feed speed of the third feed roller 9 is set according to the form of the yarn.

Two yarns Ya fed out from the third feed roller 9, Yb passes through the yarn guide 30c, thereafter, respectively, the yarn guide 30a, and passes through 30b, Volume 1 of 2 by the reciprocating movement of the belt 26 While traversing by traverse guides 27a and 27b that reciprocate in parallel with the axis of the take-up pipe 19B, they are wound around the two first take-up pipes 19B that come into contact with the rotating take-up drum 23 and thereby rotate. Two packages P are formed. At this time, the moving speed of the traverse guides 27a and 27b is controlled based on the measurement result of the rotational speed of the winding tubes 19A and 19B measured by the rotation sensor 35.

When the two packages P are fully wound, the yarns Ya and Yb are cut between the third feed roller 9 and the package P, and a doffing mechanism (not shown) rotates the cradle 20 so that the package P Is separated from the take-up drum 23 and doffed. When the winding body 40 including the two empty first winding tubes 19B is supplied to the cradle 20 and held by the bobbin holders 22a and 22b, the cradle 20 is rotated and the two first winding tubes 19B is brought into contact with the take-up drum 23. Then, the two first winding tubes 19 </ b> B start to rotate due to contact with the winding drum 23. Thereafter, the operator threads the yarn ends of the yarns Ya and Yb onto the first winding tube 19B, whereby the winding of the yarns Ya and Yb is resumed.

Here, in order to perform the yarn threading into the first take up tube 19B of the bobbin holder 22b side (left side in FIG. 3 (b)), as shown by a chain line in FIG. 4 (b), the yarn Yb, the The running direction is inclined with respect to the vertical direction of FIG. 4B so as to cross the boundary portion between the one winding tube 19B and the O-ring 43, and is brought into close contact with the outer peripheral surface of the winding body 40. Then, the yarn Yb is guided into the gap between the end and the O-ring 43 of the first winding tube 19B, by the elasticity of the O-ring 43, it is sandwiched between the end and the O-ring 43 of the first take up tube 19B to hold Is done. That is, in the present embodiment, the thread holding portion according to the present invention is formed by winding the O-ring 43 around the portion between the two insertion portions 42 of the connecting member 41. Then, when the first winding tube 19B rotates in this state, a bunch winding B is formed at the right end of the first winding tube 19B in FIG. 4B, and thereby the first winding tube 19B. The threading to is completed. At this time, as described above, instead of inclining the yarn Yb and bringing it into close contact with the outer peripheral surface of the winding tube 40, the yarn Yb is directly inserted into the boundary portion between the first winding tube 19B and the O-ring 43. May be.

On the other hand, in order to thread the first winding tube 19B on the bobbin holder 22a side (the right side in FIG. 3B), the thread Ya is urged by the bobbin holder 22a as shown by a one-dot chain line in FIG. It passes through a notch 33 formed in the portion 32. Then, the yarn Ya is guided into the gap between the end and the biasing portion 32 of the first winding tube 19B, it is held sandwiched between the end and the biasing portion 32 of the first take up tube 19B. Then, when the first winding tube 19B rotates in this state, a bunch winding B is formed at the right end of the first winding tube 19B in FIG. 3B, whereby the first winding tube 19B. The threading to is completed.

On the contrary, by guiding the yarn Yb to the gap between the end of the first winding tube 19B and the urging portion 32, the yarn Yb is connected to the end of the first winding tube 19B and the urging portion. 32, and the yarn Ya is guided to the gap between the end of the first winding tube 19B and the O-ring 43, so that the yarn Ya is connected to the end of the first winding tube 19B. It may be held between the O-ring 43 and held. In this case, the bunch winding B is formed at the left end of each first winding tube 19B in FIG. 3B.

Then, in the case of forming in this manner a plurality of packages P are the two first take up tube 19B, respectively, the yarn Ya, since the winding the Yb to form two package P, the package P After the formation, the two packages P can be separated by pulling out each first winding tube 19B from the connecting member 41 in the winding body 40 removed from the cradle 20. Therefore, unlike the above-mentioned patent document 1, in order to separate the two packages P, a complicated process of cutting the winding tube is not necessary, and the two packages P can be easily separated.

Moreover, the yarn Ya to the first take up tube 19B, when Yb is wound, the yarn Ya, by the tension of the Yb, first take up tube 19B is pushed radially inward, the case where the diameter decreases is there. However, in this embodiment, as described above, by a plurality of slits 46 into the insertion portion 42 is formed, since the diameter of the insertion portion 42 is made possible scaling, first take up tube 19B When the diameter decreases, the diameter of the insertion portion 42 decreases due to the force applied to the insertion portion 42 from the first winding tube 19B.

Therefore, it is possible to prevent the first winding tube 19B from being pulled out from the insertion portion 42 after the package P is formed. In addition, by forming the plurality of slits 46 in the insertion portion 42, the diameter of the insertion portion 42 can be easily expanded or reduced.

In this case, the first winding tube 19B on the bobbin holder 22a side is held by holding the yarn Ya introduced from the notch 33 between the urging portion 32 and the first winding tube 19B . and performing a yarn hooking to one winding tube 19B, for the first take up tube 19B of the bobbin holder 22b side, a yarn hooking by pinching and holding the yarn Yb between the O-ring and the first take up tube 19B Therefore, the two first winding tubes 19B can have a bunch winding B on the same side in the axial direction (the right side in FIG. 3). Thereby, the winding direction of the yarns Ya and Yb of the two first winding tubes 19B can be made the same.

Further, by winding the O-ring 43 around the portion between the two insertion portions 42 of the connecting member 41, a yarn holding portion for holding the yarn Yb with the first winding tube 19B can be provided with a simple configuration. Can be formed.

  Next, an operation for forming one package P will be described. In this case, in the same manner as described above, the two yarns Ya and Yb that are twisted while being stretched between the first feed roller 6 and the upstream second feed roller 7 are transferred to the upstream second feed roller 7. Are both guided to one interlace nozzle 16b, combined with the interlace nozzle 16b, and then fed to the second feed roller 8 on the downstream side.

  The yarn Yg formed by the combined yarn is relaxed between the second feed roller 8 and the third feed roller 9 on the downstream side, and in this state, the heat is relaxed in the secondary heater 17, and the third feed roller 9 is sent.

As shown in FIG. 3A, the yarn Yg fed from the third feed roller 9 passes through the yarn guide 30c that is further away from the traverse guide 27b than the yarn guides 30a and 30b, and directly from the yarn guide 30c. It is sent to the traverse guide 27b. Then, the belt body 26 abuts on the rotating winding drum 23 while traversing around the yarn guide 30c by a traverse guide 27b that reciprocates in parallel with the axis of one second winding tube 19A by reciprocating travel of the belt body 26. One package P is formed by being wound around one second winding tube 19A.

In the present embodiment, the travel width of the traverse guide 27b when winding the yarn Yg around one second winding tube 19A is the traverse guide when winding the yarns Ya and Yb around the two first winding tubes 19B. It is larger than the movement width of 27a, 27b. Therefore, in this way, by causing the yarn Yg to traverse around the yarn guide 30c that is further away from the traverse guide 27b than the yarn guides 30a and 30b, the bending angles of the yarns Ya and Yb in the yarn guides 30a and 30b, The bending angle of the yarn Yg in the yarn guide 30c is set to be approximately the same.

  Further, when forming one package in this way, the traverse guide 27a is removed from the belt body 26 in advance so that the traverse guide 27a does not interfere with the movement of the traverse guide 27b. The traverse guide 27b may be removed instead of the traverse guide 27a.

Even when a single package is formed, when the package P is fully wound, the package P is separated from the winding drum 23 and doffed as described above. After that, when the empty second winding tube 19A is supplied to the cradle 20 and held by the bobbin holders 22a and 22b, the cradle 20 is rotated, and the second winding tube 19A is moved with respect to the winding drum 23. The contact state is assumed. The second winding tube 19 </ b> A starts to rotate due to the contact with the winding drum 23. Thereafter, the operator places the yarn end of the yarn Yg on the second winding tube 19A, and thereby the winding of the yarn Yg is resumed.
