切断できる。Further, in the apparatus according to the second aspect, the yarn is hooked on the bobbin-side yarn hooking portion and the outer yarn hooking portion, and the bobbin-side yarn is held between the bobbin side collar and the bobbin end face.
Next, the yarn between the yarn hooking portions is cut by the fixed blade. In this case, if the outer yarn hooking portion is arranged rearward in the bin rotation direction as described in claim 3, even if the notch of the outer yarn hooking portion is made shallow, the yarn will surely reach the deepest portion of the bobbin-side yarn hooking portion. As it is pulled in, the yarn on the bobbin side can be securely clamped
Since the outer thread hooking portion is shallow, the thread is located at the shallow portion of the circumferential groove, and the thread reliably contacts the fixed blade. Further, since the yarn abuts on the fixed blade obliquely, the impact of the yarn cutting is small and the yarn can be cut cleanly.

By the rotation of the thread hook arm, the outer thread locking portion locks the yarn captured by the suction member or the like and guides the yarn to the outside of the bobbin holder. From the yarn supply side, is guided to the bobbin side of the bobbin holder, and the thread that is slantly stretched between these thread locking portions is looped over the thread hooking portion of the bobbin holder. At this time, since the yarn continuing on the yarn supply side is guided by the yarn engaging portion on the bobbin side, the hung yarn is securely clamped between the bobbin end face and the collar. Further, the thread hook arm is stopped at that position for a while, and performs the bunch winding by the bobbin-side thread locking portion.

に切除可能となる。The cradle arm is rotatably supported,
Respectively, and the convex portion to be fitted to the bobbin to wind the yarn, to form a flange for supporting the by bobbin end surface rising from the convex portion peripheral surface, e Bei the contracture Jisuru pair of bobbin holders to the bobbin from both sides, at least one A part of the outer periphery of the collar of the bobbin holder is cut out to form a yarn hooking part;
The deepest part of the hanging part will exceed the part that contacts the bobbin end face
As a result , the yarn passed over the yarn hooking section is clamped between the collar and the bobbin end surface, so that the yarn is securely wound around the bobbin. Become.

クション部材で吸引し除去できる。Further, an outer collar is provided on the side opposite to the bobbin of the collar supporting the bobbin end face, a circumferential groove is formed between them on the entire circumference of the bobbin holder, and a thread hooking portion is also formed on the outer collar. In addition, since the fixed blade is provided in the circumferential groove, the end of the yarn hung on the bobbin can be reliably cut in the vicinity of the position where the yarn is hung. For this reason, the end of the yarn hung on the bobbin is the shortest, and the yarn end does not get entangled with the bobbin holder or slip off during doffing. In addition, since the yarn end is cut immediately after the yarn is wound, if the yarn end has been previously suctioned and captured by the suction member, the captured yarn end will be cut before being pulled out from the suction member, The cut yarn end can be sucked and removed by the suction member as it is.

業者に対して安全である。Further, since the yarn hooking portion of the outer collar is arranged with a phase difference rearward in the bobbin rotation direction with respect to the yarn hooking portion of the bobbin-side collar, the yarn is wound by the bobbin-side yarn hooking portion. The notch on the outer thread hook can be made shallower while firmly clamping, and the thread can be cut more reliably, and the deep notch on the bobbin side thread hook is safe for workers without being exposed to the outside. is there.

き用の糸ガイドを廃止できる。As a yarn hooking device for the yarn winding device, a bobbin holder and a tip of a yarn hooking arm rotatable from a standby position toward a bobbin holder in a virtual plane substantially parallel to the bobbin rotation axis direction are provided. A turning radius protrudingly provided at a turning radius position that does not intersect, the turning radius being located rearward in the turning direction with respect to the outer thread holding portion, and intersecting with the bobbin holder on an extension of the turning locus. Since the bobbin-side thread locking portion is protruded at the position, the thread can be wound around the bobbin holder by a simple operation of rotating the thread hook arm, and the automatic doffer can be easily configured. In addition, by guiding the yarn at the bobbin-side yarn locking portion, the yarn can be securely clamped between the bobbin end face and the brim. A predetermined bunch winding can be formed, and a bunch winding slit on the bobbin peripheral surface and a bunch winding thread guide can be eliminated.
