要求されていた。B. Prior Art In order to wind a filament (hereinafter referred to as a yarn) such as yarn or fiber onto a rotating body, the end of the yarn must be grasped at the beginning of the winding, and when the winding is finished, the end of the yarn must be grasped. In order to cut the end, it is necessary to grasp the thread end. When the rotation of the winding body stops, the grip on the thread must be released, which requires a fairly complicated function.

接可能な抜止めピンとを含むことである。D. Means for solving the problems In order to achieve the above object, the structure of the present invention is as follows. That is, the claw member includes a claw member provided near the outer periphery of the distal end surface of the rotary body for winding the thread, and a mounting rod protruding from the distal end surface of the rotary body and penetrating the claw member. a rod hole that is long along the radial direction of the rotating body; and a slope that approaches the tip surface of the rotating body as it reaches the outer side in the radial direction of the rotating body, on a surface opposite to the surface facing the rotating body. A cutout portion having a surface formed thereon, and a chamfered portion formed on a front outer edge along the rotational direction of the rotating body on the surface facing the rotating body,
The mounting rod includes a rod main body that can be inserted into the rotating body by passing through the rod hole of the claw member, and a retaining pin that is fixed to the tip of the rod main body and can slide on the inclined surface of the claw member. It is to include.

回転体との隙間を生じて、糸を解放する。E Effect: Under the influence of centrifugal force when the rotating body rotates, the pawl member, while being supported by the mounting rod, slides into contact with the tip surface of the rotating body and moves radially outward. As the claw member moves, the inclined surface of the cut-out portion comes into sliding contact with the retaining pin of the attachment rod, so that the claw member is forced onto the distal end surface of the rotating body. Then, the claw member pinches and grips the thread between the claw member and the distal end surface of the rotating body. Similarly, at the end of winding, the end portion of the winding yarn pushed out to the vicinity of the tip of the rotating body is gripped by the claw member. When the rotating body stops, the centrifugal force of the claw member disappears, and the member moves toward the center of the rotating body,
Create a gap with the rotating body to release the thread.

されたボビンCの表面に巻きとられる。 As shown in FIG. 1, prior to the start of winding, the piston cylinder mechanism 15a operates and the thread D is pushed out to the front of the bobbin holder 10 by the thread guide rod 15, and the thread end is placed above the waist processing machine B. It is hanging down. When the air valve 21a is opened and compressed air is introduced into the processing machine main body 20, the air draws in the yarn D and is discharged from the exhaust pipe 22. In this state, the bobbin holder 10 has not yet reached a predetermined rotation and the centrifugal force is not sufficiently applied, so the claw member 30 is closer to the center of the bobbin holder 10 as shown in FIG. When the bobbin holder 10 reaches a predetermined rotation, the claw members 30 move radially outward of the bobbin holder 10 as shown in the third figure due to the action of centrifugal force. As a result of this movement, each claw member 30 is pressed against the distal end surface 10a of the bobbin holder 10 with the inclined surface 32a being held by the retaining pin 42. Here, when the thread guide 15 retreats, the thread D is drawn toward the proximal end of the bobbin holder 10 due to tension,
It enters between the bobbin holder 10 and the claw member 30 through the chamfered portion 33 of one of the claw members 30, is firmly gripped between them, and is cut by touching the cutter 25. The end portion of the cut yarn D is shaken down into the waist box 24, but the original portion is held by the claw member 30 as the yarn end D1 at the beginning of winding, as shown in the second figure, so that the following The portion is guided to a traverse mechanism (not shown) and wound onto the surface of the bobbin C attached to the bobbin holder 10.

ビンホルダ10に残ることがない。 When the winding is completed, the thread guide rod 15 moves forward again, and the bobbin holder 10 stops while maintaining the same relative position as at the beginning of the winding. 1
5 touches the tip of the cutter 25 and is cut. When the bobbin holder 10 stops, the claw member 30, which has lost its centrifugal force, moves toward the center of the holder and releases the end of the winding yarn from the gripping state.
The winding end yarn end D2 is easily removed together with the winding bobbin without getting in the way at all, and no waist yarn remains in the bobbin holder 10.
