The front frame n8 'is pivotally supported by an axis n30 that extends through the front end of the rear frame n8 ". Further, a semicircular tooth n31 is engraved on a side portion of the front frame n8 ′ on the rear frame n8 ″ side.
A gear n32 screwed with 31 is attached to a shaft n33 provided on the rear frame n8 ″. A gear n34 is further attached to the shaft n33, and the gear n34 has a rear frame n8 ″. A gear n36 attached to an output shaft n35 'of a motor n35 capable of normal and reverse rotation arranged on the upper surface is screwed. In addition, in FIG. 5 and FIG.
The cylinder member n16 is arranged on the horizontal frame n8, but in the present embodiment, the piston / cylinder member n16 is arranged on the front frame n8 '.

With the above-described structure, the output shaft n35 ', the gear n36, and the gear n36 are appropriately driven by driving the motor n35 disposed on the upper surface of the rear frame n8 ".
By rotating the semicircular tooth n31 engraved on the side portion of the front frame n8 ′ via the gears n34 and n32, the front frame n8 ′ is vertically swung about the axis n30. Is configured to be able to. Therefore, since the upper plate U is curved, the bobbin carrier C
Even if the mast c4 is inclined, the front frame n8 ′ can be swung to position the front frame n8 ′ substantially at right angles to the mast c4 in accordance with the inclination of the mast c4. The mast c4 can be more reliably gripped by the gripping arms n19 and n20.

It should be noted that the present invention is not limited to the braider B having the curved upper plate U arranged in the machine base Fb having the horizontal axis and the substantially cylindrical shape, which is used in the above-mentioned embodiments, and various types are usable. The above-mentioned exchanging device N, yarn conveying device T, etc. can be applied to the braider, and the above-mentioned clamper device is provided so that the horizontal frame n8 of the exchanging device N does not interfere with the movement of the bobbin carrier C. With the same structure as the structure in which T ′ is slid horizontally,
The gripping arms n19 and n20 arranged at the tip of the horizontal frame n8 can be configured to be slidable in the longitudinal direction of the horizontal frame n8.

As described above, it is detected that the bobbin c6 mounted on the bobbin carrier C traveling along the track u1 formed in the upper plate U has become an empty bobbin, and the full bobbin is mounted. The bobbin carrier C can be automatically replaced, and the yarns Y of the full bobbin can be attached to the braid B in the composition by the clamper device T ′ of the yarn conveying device T.
Since it can be incorporated, the worker does not have to move to the bobbin carrier C stopped at various positions on the track u1 to perform the replacement work as in the conventional case, and the productivity of the braider B is improved. At the same time, automation of Braider B can be achieved.

[0051]

Since the present invention is constructed as described above, it has the following effects. The worker does not have to move to the bobbin carrier stopped at various positions on the track to perform the replacement work, so that the productivity of the braider can be improved and the braider can be automated.
