Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to weft length measurement storage and the above-mentioned bobbin winding by engagement and disengagement of a bobbin winding surface formed by a plurality of bobbin winding surface forming bodies and a weft locking body. The present invention relates to a weft measuring and storing device in a jet loom for controlling the pulling out of the weft from the attached surface.

[0002]

2. Description of the Related Art The storage posture of wefts wound and stored on a yarn winding surface, that is, the arrangement posture of the wound yarns affects the quality of the weft insertion state. Since the attitude of the wound yarn is influenced by the type of weft, the oil agent attached to the weft, and the like, it is necessary to select a yarn winding surface forming body suitable for the weft used.

In the apparatus disclosed in Japanese Patent Laid-Open No. 63-35855, a plurality of annularly arranged divided bodies form a length measuring drum, and the length measuring drum is held stationary by the magnetic action of a plurality of magnet pairs. . The thread winding surface on each of the divided bodies has a different friction coefficient surface, and one of the divided bodies is selectively arranged at a position having an engagement / disengagement relationship with the weft engaging body. This selective arrangement is performed by manually rotating the length measuring drum.

[0004]

Although the above arrangement can be performed very easily, the only divisional body suitable for the weft thread to be used is the divisional body in a position in which the weft thread locking body is in the engagement / disengagement relationship. Therefore, the entire wound surface does not have a friction coefficient surface suitable for the weft used, and the arranging posture of the wound thread cannot be said to be optimum.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a weft measuring and storing device capable of easily exchanging a member forming a winding surface while ensuring an optimal arrangement posture of winding threads.

According to the second aspect of the present invention, the sliding contact surface of the thread winding surface forming body is arranged at a rotationally symmetrical position about the mounting center position of the thread winding surface forming body on the support base. In the invention of claim 3, the replacement support mechanism is a screw for fastening and fixing the thread winding surface forming body to the support base, and the screwing position of this screw is the mounting center position.

According to the invention of claim 4, the mounting position of the supporting base can be adjusted in the radial direction of the bobbin winding surface.

[0009]

The sliding contact surface on the bobbin winding surface forming body is replaced with the bobbin winding surface forming position according to the weft used. This replacement arrangement is performed with the replacement support mechanism in a replaceable state.

According to the second aspect of the present invention, when the thread winding surface forming body is rotated about the mounting central position of the thread winding surface forming body on the support base, a plurality of sliding contact surfaces are centered on the mounting position central position. And shift to rotation. The sliding contact surface is replaced by rotating the bobbin winding surface forming body.
