記糸巻付面上の巻付貯留糸の緯入れを制御する無杼織機
における緯糸測長貯留装置に関するものである。Detailed Description of the Invention Object of the Invention (Industrial Application Field) The present invention provides a weft locking body that winds a weft supplied from a weft supply source onto a yarn winding surface and engages and disengages from a similar winding surface. The present invention relates to a weft length measurement and storage device for a shuttleless loom that controls weft insertion of the wound storage yarn on the yarn winding surface.

従来の緯糸係止体は糸巻付面を形成するドラムの中心軸
線と直交する方向へ往復動されるようになっている。The weft insertion control of the weft locking body releases the stored yarn on the thread winding surface in synchronization with the weft insertion start timing, and the stored yarn necessary for weft insertion moves from the weft locking position to the weft insertion side. After the weft transfer, the weft thread locking body engages with the thread winding surface again to lock the weft on the thread winding surface. Conventional weft thread locking bodies that perform such weft insertion control engage the thread winding surface again. It is designed to be reciprocated in a direction perpendicular to the central axis of the drum being formed.

まで巻糸の追随現象が続く。In other words, the appearance of the winding yarn, such as the winding yarn going back and forth or the yarns becoming entangled with each other due to yarn fuzz, has an adverse effect on the insertion state of the weft yarns, which greatly affects the quality of the woven fabric. Therefore, the above-mentioned winding pattern should be avoided as much as possible. However, in the conventional weft insertion control of the weft locking body, the first winding of the wound storage yarn that is locked on the weft locking body moves the weft in the direction in which the first winding yarn of the wound storage yarn is released. Following the movement of the body, the first winding thread intersects with the following winding thread. Such a phenomenon makes it difficult for winding yarns to separate from each other, especially in the case of a weft yarn with a lot of fuzz, which hinders achieving proper weft insertion. The first one is locked in contact with the weft locking body.
The reason why the second winding thread follows the interlocking movement of the weft thread locking body is that the weft thread locking body moves in a direction perpendicular to the central axis of the thread winding surface, and the weft thread locks while being pulled in the weft insertion direction. The following phenomenon of the winding yarn continues until the component of the weft tension in the interlocking direction of the weft yarn anchoring body becomes larger than the frictional force between the weft yarn anchored to the body and the weft yarn anchoring body.

前記軸線に対して傾斜させた。Structure of the Invention (Means for Solving the Problem) In order to avoid the following phenomenon of the winding yarn as described above, the present invention focuses on the yarn locking part of the weft locking body, The weft locking body is linked to a reciprocating drive mechanism for reciprocating the weft locking body in a plane where the weft locking body is moved back and forth in a reciprocating state of the weft locking body to release the wound stored yarn. The yarn locking portion of the weft locking body is inclined with respect to the axis so that the wound storage yarn is held in the same position or guided while being locked in the weft insertion direction.

される。(Function) That is, when the weft locking body engages with and disengages from the yarn winding surface from the outside of the yarn winding surface, the yarn locking portion of the weft yarn locking body moves to the side opposite to the weft insertion side with respect to the central axis. It's leaning. When the weft thread locking body moves back in the direction of releasing the wound stored yarn, that is, when it detaches outward from the yarn winding surface, the friction between the weft thread locked in the yarn locking part and the same type of locking part occurs. The force is smaller than that in the conventional orthogonal state, and the first winding thread that is locked to the weft locking body is suppressed from following the interlocking movement of the weft locking body.

制される。When the weft thread locking body engages with and disengages from the thread winding surface from inside the thread winding surface, the thread locking portion of the weft thread locking body is inclined toward the weft insertion side with respect to the central axis. When the weft locking body moves back in the direction of releasing the wound stored yarn, that is, when it separates inward from the yarn winding surface, the frictional force between the weft and the yarn locking portion is changed from the conventional orthogonal state as described above. As a result, the first winding yarn that is locked to the weft locking body is suppressed from following the weft locking body.

て係止されながら緯入れ側へ移行する。Now, as shown in FIG. 2, the cam follower 15a is connected to the cam 1.
1, and the weft locking body 17 is spaced apart from the yarn winding surface as shown in FIG. 1.2.3. Therefore,
The wound storage yarn Y1 on the straight circumferential surface 8b of the yarn winding surface is pulled out. When all of the wound stored yarn Y1 moves from the locking position with the weft locking body 17 to the weft insertion side, the cam follower 15a moves to the crest of the cam 11, and the tip of the weft locking body 17 touches the thread winding surface. intersect. The movement of the weft thread locking body 17 is performed in the swinging direction of the swinging lever 15, that is, within a plane perpendicular to the central axis C. As shown in FIG. 4, while the weft thread stopper 17 intersects with the yarn winding surface, the weft Y, which is wound and supplied from the thread winding tube 6 onto the Taber peripheral surface 8a, is wrapped around the weft thread stopper 1.
7 and is wound and stored on the tapered peripheral surface 8a. When the weft yarn Y is wound and stored three and a half times on the tapered circumferential surface 8a, the cam follower 15a begins to move from the peak part of the cam 11 to the trough part, and the weft yarn stopper 17 is wound and stored as shown in FIG. As soon as the weft starts to separate from the surface, the main weft insertion nozzle is activated. Since the weft locking body 17, which is inclined toward the weft insertion side and the opposite side with respect to the center axis C, is removed within the plane perpendicular to the center axis C, the weft lock that locks the wound storage yarn Y1 is removed. The intersection between the yarn locking portion 17a of the body 17 and the yarn winding surface moves toward the weft insertion side. Therefore, the wound stored yarn Y1 on the tapered circumferential surface 8a moves to the weft insertion side while being locked at the yarn locking portion 17a of the weft locking body 17.

緯入れ状態を得ることができる。The first winding yarn of the wound stored yarn Y1 is pulled toward the weft insertion side by the operation of the weft insertion main nozzle, and the yarn is stopped by the weft locking body 17 that is moving in the detachment direction from the yarn winding surface. It is pressed against the portion 17c. Therefore, a frictional force is generated between the weft locking body 17 moving in the detachment direction from the yarn winding surface and the first wound yarn, but the yarn locking portion 17a is
1, that is, since the weft yarn Y is inclined toward the side opposite to the weft insertion side with respect to the drawing direction, the component of the tension of the first wound yarn toward the yarn winding surface side exceeds the frictional force, and the first The winding yarn does not follow the movement of the weft locking body 17. Therefore, as shown in FIG. 6, when the weft locking body 17 is separated from the yarn winding surface, the wound yarns do not intersect with each other.
Thread layering of the weft yarns during weft insertion is performed well, and an appropriate weft insertion state can be obtained.

According to the structure of the present invention in which the yarn locking portion is tilted to either side with respect to the central axis of the yarn winding surface, the yarn locking portion is tilted to either side with respect to the central axis of the yarn winding surface, so that the yarn locking portion is tilted in either direction when the weft yarn locking portion is moved in the direction of releasing the wound stored yarn on the drum. It is possible to suppress the frictional force between the stopper and the weft to avoid the phenomenon of the weft following the weft stopper, and it has the excellent effect of preventing weft insertion failures due to interlacing of the winding yarns. .

In the storage device, the weft locking body is linked to a reciprocating drive mechanism to reciprocate the weft locking body within a plane intersecting the axis of the yarn winding surface, and the weft locking body is coupled to a reciprocating drive mechanism to release the wound stored yarn. The yarn locking portion of the weft locking body is aligned with the axis so that the weft locking body locks and holds the wound stored yarn at the same position or guides the wound storage yarn while locking it in the weft insertion direction in the backward movement state of the stopper body. A weft length measuring and storage device for a shuttleless loom tilted against the ground.
