よび糸の切断を行うを一般とする。(Prior Art) As a turret type winding machine, a winding machine in which a winding ball moves in a separating direction with respect to a traverse device with an increase in the diameter of the winding ball in a winding operation, or a winding ball which performs winding at a fixed position. On the other hand, in some cases, the traverse position moves away from the traverse position.However, in either case, the conventional yarn is separated from the traverse guide as a means for switching the yarn when the winding is full, and the yarn is moved by a separate guide to the normal traverse position. In general, the yarn is wound around an empty bobbin and cut while holding the yarn by a yarn holding means or the like provided at the base of the bobbin holder or the like.

障とその保全補修等が面倒となる問題があった。However, in the case of using a dedicated thread switching guide other than the traverse guide as described above, a mechanism for driving the guide is required, and the operation becomes inevitably impossible because the apparatus becomes complicated and the number of times of thread transfer increases. There is a problem that it becomes accurate, and trouble of the mechanism and maintenance and repair thereof become troublesome.

元の綾振り状態位置に復帰させる構成のタレット型巻糸
機を先に提案した(特願平1-249191号参照)。For this reason, the inventor of the present invention eliminates the above-mentioned conventional inconveniences, simplifies the means for switching the yarn at the time of full winding, and engages the yarn guide in an endless form provided on the outer periphery for the purpose of accurate operation. By shifting the traverse cam constantly traversed by a required distance, the turning point of the yarn guide is deviated to a position beyond the yarn holding means provided at the end of the bobbin holder, and the traverse operation of the yarn guide is used. A turret type winder was proposed in which the traverse cam was forcibly guided to the yarn end holding means, and after completion of the yarn end holding, the traverse cam was returned to the original traverse state of the yarn guide. -249191).

の点について更に改善すべき余地が残されていった。(Problems to be Solved by the Invention) However, in the yarn end holding means of the turret type winder according to the above proposal, the annular gripping member is pressed against the holding surface formed at the end of each bobbin holder by a spring. In the case where the yarn end is fixed to the bobbin holder on the empty bobbin side at the time of yarn switching, the yarn is wound between the two through a V-shaped opening formed in the mating surface of the holding surface and the gripping member. Since the yarn end is digged in using tension, there is a concern that the yarn end cannot be reliably held, and there is room for further improvement in this regard.

By operating the means (43), the traverse cam (4a) is displaced by a predetermined stroke from a normal traverse operation position shown by a solid line in FIG. 3 to a position shown by a two-dot chain line in FIG. Then, along with this, the traversing operation range of the yarn guide (5) is shifted toward the base end side of the bobbin by a length corresponding to the shift distance of the traverse cam (4a),
On the way, the yarn Y on the supply side is forcibly carried to the yarn holding means (38) at the base end of the holder (1b) of the empty bobbin. At this time, the yarn holding means (38) separates the gripping member (33) from the end face of the holder (1b) with the operation of the shift means (43), and a gap is generated between the two, so that the yarn holding means (38) (38)

ビン(3b)への糸の切替えが完了する。As described above, the thread guide (5) folded back from the tip of the empty bobbin (3b) is biased toward the base end side of the bobbin holder by a length corresponding to the shift distance of the traverse cam (4a). And traverses to the yarn holding means (38) outside the base end of the empty bobbin (3b) to forcibly supply the supply yarn Y to the yarn holding means (38). (33) and the friction member (36), and when the yarn guide (5) turns around at the base end of the holder and changes direction, the limit switch (53) acts to reverse the air cylinder (43). The contact piece (48) moves away from the cam follower (40) to return the traverse cam (4a) to the normal traverse motion position, and the gripping member (33) is pushed back by the elastic force of the compression spring (37). As a result, the yarn end is securely sandwiched between the friction member (36) and the gripping member (33). Thus, the winding yarn is wound on the bobbin (3b) with the sandwiched portion sandwiched between the friction member (36) and the gripping member (33) as the winding yarn starting end, and this portion is separated from the normal winding position. Since the bobbin is lifted in the rotating direction, the continuous yarn Y 'extending from the full bobbin (3a) to the empty bobbin (3b) is given an appropriate tension, and is pressed against the thread cutting blade (51) provided on the path. The yarn is cut, and as a result, the switching of the yarn from the full bobbin (3a) to the empty bobbin (3b) is completed.

When this reaches the doffing start position C shown in FIG. 2, the abutting of the cam follower (40) and the arcuate plate cam (41) causes the annular gripping member (33) to be separated from the end surface of the bobbin and pinched as described above. Release the end of the wound thread.

来るという効果を発揮する。(Effects of the Invention) As described above, the yarn end holding device of the present invention shifts the traverse cam when the bobbin holder holding the empty bobbin reaches the winding start position during the yarn switching operation, and simultaneously shifts the traverse cam. Using the shift operation, the yarn gripping part of the yarn holding means provided at the end of the bobbin holder is opened, and the yarn is forcibly moved to the yarn gripping part of the yarn holding means by the traverse movement of the yarn guide by the rotation of the traverse cam. The traverse cam is moved to the normal position, and then the traverse cam is shifted to the normal position to close the yarn gripping part. This has the effect that the operation can be performed reliably.

を抑制し得るという効果も期待できる。In addition, according to the present invention, since the opening and closing of the yarn holding means is performed by utilizing the function of the shifting means of the traverse cam, it is easy to synchronize the reciprocating operation of the yarn guide with the opening and closing operation timing of the yarn holding means. In addition, there is no need to separately provide a drive source for opening and closing the yarn holding means, and an effect of suppressing a rise in apparatus cost can be expected.
