The horizontal movement of the horizontal movement frame b1 for moving the mandrel m horizontally toward and away from the curved upper plate U having the track arranged in the braider body Bb is described above. Thus, the pinion b7 is rotationally driven by driving the motor b6 that can rotate in the forward and reverse directions, and the rack b5 screwed to the pinion b7 is horizontally driven.

Next, the movement of the mandrel m in a direction substantially orthogonal to the movement in the horizontal direction approaching or moving away from the curved upper plate U will be described. When the pinion b10 is rotated counterclockwise in FIG. 10 from the state shown by the solid line in FIG. 10 by the rotation of the motor b9 that can rotate in the normal and reverse directions, the fan-shaped rack b22 screwed to the pinion b10 is driven.

When the fan-shaped moving member b17 moves downward and the pulley b23 attached to the fan-shaped moving member b17 also moves downward, the endless belt b24 is fixed to the tip of the horizontal moving frame b1 at the point X. Therefore, the endless belt b24 on the opposite side across the pulley b23 is pulled downward in FIG. 18 to rotate the endless belt b24 counterclockwise. Since the mandrel support moving member b26 is fixed to the endless belt b24 at the point Z, the mandrel support moving member b26 also moves downward in FIG. 9 when the endless belt b24 rotates counterclockwise. At this time, due to the above-mentioned configuration, the mandrel support moving member b26 moves twice with respect to the moving amount of the pulley b23, and the mandrel support moving member 26 can be moved quickly.

Next, the load detecting device T of the mandrel m will be described with reference to FIG. 11 which is a sectional view taken along the line II of FIG. A cylindrical recess t1 is bored at the end of the mandrel m on the side of the support plate b34 ′, while the support plate b34 ′ has a cylindrical shaft portion t2 having a diameter smaller than the inner diameter of the recess t1 of the mandrel m. It is projected. The piezoelectric element t3 is mounted in the gap generated when the cylindrical shaft portion t2 of the support plate b34 ′ is fitted into the recess t1 of the mandrel m. Via the piezoelectric element t3, the concave portion t of the mandrel m

Reference numerals t5 and t5 ′ are through holes formed in the support plate b34 ′, and the conductive lines t6 and t6 ′ of the piezoelectric element t3 are arranged at appropriate positions of the mandrel device Bm through the through holes t5 and t5 ′. Connected to the detector t7.

When the yarn Y unwound from a certain bobbin carrier C is subjected to an abnormal tension due to the inability to release the yarn Y from the bobbin c6 or the like in the composition, a load is applied to the mandrel m. . This load is detected by the detector t7 as a voltage change of the piezoelectric element t3, and a detection signal is sent to a braider drive control unit (not shown) to stop the drive of the braider BR or the mandrel device Bm.

FIG. 12 shows a load detecting device T for the mandrel m.
FIG. 12 is a cross-sectional view similar to FIG. 11 showing another embodiment of FIG.
In the embodiment shown in FIG. 2, the cylindrical magnet t8 is attached to the inner peripheral surface of the concave portion t1 of the mandrel m, and the coil t9 is arranged on the cylindrical shaft portion t2 of the opposing support plate b34 ′. There is. Therefore, when an abnormal tension acts on the yarn Y and the mandrel m moves with respect to the support plate b34 ', a current is generated in the coil t9. This current is detected by the detector t10, and the drive of the braider BR or the mandrel device Bm is stopped.

The above-mentioned piezoelectric element t3 or magnet t8
Need not necessarily be formed into a cylindrical shape, and the support plate b3
It is also possible to arrange a predetermined number of 4's and the mandrel m at equal intervals. Furthermore, the load detection device T is attached to the support plate b34 '

It is also possible to dispose between the support frames b26 and b26 'which are provided upright on the upper part of 6 and the support rod b34.

By disposing the load detecting device T as described above, not only the cutting of the yarn Y unwound from the bobbin carrier C or the detection of abnormal tension but also the failure of the mandrel device Bm itself, It is also possible to detect the load applied to the mandrel m when the mandrel m is not in the proper position. Further, the composition of the braid is completed on the mandrel m, and the motor b of the mandrel device Bm capable of rotating in the forward and reverse directions.
When the horizontal moving frame b1 is moved to the right in FIG. 2 by driving 6 and the second composition position stability guide member g2 of the composition position stability guide member G is used to focus the yarn Y connected to the braid, a bobbin carrier Even when a load is applied to the mandrel m due to an abnormal tension applied to the yarn Y from C, or when the yarn Y is caught by a component of the braider BR, this load is detected and the mandrel device Bm is detected. Can be stopped.

Since the present invention is constructed as described above, it has the following effects. Since the load on the mandrel or the mandrel support device is detected by the load detection device and the drive of the braider or the like is stopped, the mandrel is abnormally loaded, the mandrel support device is damaged, or the bobbin carrier is damaged. It is possible to prevent the other parts of the braider from being damaged.
