Further, in order to move the mandrel support moving member b26 upward from the lowermost position shown by the chain double-dashed line, the forward / reverse rotatable motor b9 is reversely rotated and the pinion b10 is rotated clockwise in FIG. Let

Next, referring to FIGS. 21 to 23, which are schematic plan views showing the composition process, the braider BR of the present invention is used, and as an example, a T-shaped mask as shown in FIG. The sequence of steps for forming the braid on the ndrel m will be described.

(A) First, in a state where the drive of the braider body Bb is stopped and the traveling of the bobbin carrier C 1 is stopped, the horizontal moving frame b1 is moved rightward in FIG. )), One end of a T-shaped mandrel m (hereinafter, simply referred to as "mandrel m". A short portion m1 orthogonal to a long portion of the T-shaped mandrel m is referred to as a "branch portion"). (1) is attached to the mandrel mounting plate b34 'shown in FIG. After that, the horizontal moving frame b1 is moved to the left in FIG. 2 and the fan-shaped moving member b17 is appropriately moved to set the composition point P to one end (1) of the mandrel m as shown in FIG. 21 (a). (For convenience of explanation, the end of the mandrel m attached to the mandrel mounting plate b34 ′ is marked with an inverted triangle (∇).).

(B) From this state, the drive device D is driven to drive the bobbin carrier C along the track to start composition, and the horizontal moving frame b1 is gradually moved to the right in FIG. 21 (b), the composition is performed toward the joint j of the mandrel m.

(C) After composition to the joint j of the mandrel m, the movement of the horizontal moving frame b1 is stopped, and then the fan-shaped moving member b17 is moved upward in FIG. 18 to obtain the state shown in FIG. 21 (c). The mandrel m is rotated as shown to bring it into the state shown in FIG. From this state, the horizontal moving frame b1 is moved further to the right in FIG. 2 to form the branch portion m1 of the mandrel m as shown in FIG. It is also possible to slow down the moving speed without stopping the movement of the horizontal moving frame b 1 and simultaneously move the fan-shaped moving member b 17.

(D) As shown in FIG. 21 (e), when the composition reaches the end of the branching portion m1 of the mandrel m, the movement of the horizontal moving frame b1 is stopped and the driving device D is stopped to stop the bobbin. Stop traveling of the carrier C. Then, as shown in FIG. 21 (f), one end (1) of the mandrel m is detached from the mandrel mounting plate b34 ′, the mandrel m is rotated 180 degrees, and the side opposite to the one end (1) of the mandrel m. One end (2) is attached to the mandrel mounting plate b34 '.

(E) After attaching one end (2) of the mandrel m to the mandrel mounting plate b34 ', the drive of the drive device D is restarted to start the traveling of the bobbin carrier C and the horizontal moving frame b1 is shown in FIG. In FIG. 22 (a), the branch portion m1 of the mandrel m is recomposed as shown in FIG. 22 (a).

(F) After composition to the joint j of the mandrel m, the drive unit D is stopped to stop the bobbin carrier C from traveling and the horizontal moving frame b1 to stop moving, so that the fan-shaped moving member b17 is illustrated. At 18, the mandrel m is rotated to the position shown in FIG. 22 (b). In this state, the driving device D is driven to resume the traveling of the bobbin carrier C to start the composition, and the fan-shaped moving member b17 is moved further downward to the state shown in FIG. , The horizontal moving frame b1 is moved to the left in FIG. 2 to form the composition up to the end of the mandrel m, as shown in FIG. 22 (d).

(G) As shown in FIG. 22 (d), after composition to the end of the mandrel m, the horizontal moving frame b1 is moved to the right in FIG. As shown, the composition is directed towards the junction j of the mandrel m.

(H) While the composition has advanced to the vicinity of the joint j of the mandrel m, the fan-shaped moving member b17 is moved upward while moving the horizontal moving frame b1 to the right in FIG. In the state shown in b), the movement of the horizontal moving frame b1 is stopped and the drive unit D is stopped to stop the traveling of the bin carrier C in this state.

(I) Next, the fan-shaped moving member b17 is moved downward to bring the mandrel m into the state shown in FIG. 23 (c). After that, the drive of the drive device D is restarted, the traveling of the bobbin carrier C is started, and the horizontal moving frame b1 is moved to the right in FIG. 2 to move the mandrel m of the mandrel m as shown in FIG. The joint j is assembled.

(E) Next, the fan-shaped moving member b17 is moved upward to bring the mandrel m into the state as shown in FIG. 23 (e) and to move the horizontal moving frame b1 in FIG. 23F, the composition is performed up to the end of the mandrel m, and the composition to the mandrel m is completed.

(L) After the composition of the mandrel m is completed, the drive unit D is stopped and the traveling of the bin carrier C is stopped.

(E) Next, the horizontal moving frame b1 is largely moved rightward in FIG. 2 to move the mandrel m to a position beyond the disc cutter s12 of the cutting device S. From this state, the motor s3 is rotated to rotate the disk cutter s12 at high speed as described above. On the other hand, with the rotation of the output shaft s6 rotated at a low speed by the motor s3 via the speed reducer s2, the lever s17 is moved from the standby position shown by the two-dot chain line in FIG. 16 to the operating position shown by the solid line. To rotate. Along with the clockwise rotation of the lever s17 in FIG. 16, the lever s9 also rotates toward the operating position similarly to the lever s17. By the rotation of the lever s9, the braid that is bent and converged by the second composition position stabilizing guide member g2 is connected to the horizontal guide groove s14 ′ of the guide member s14 attached to the tip of the lever s9. The large number of yarns Y 1 are guided and brought into contact with the disk cutter s 12 attached to the pulley s 13 and rotating at a high speed to cut the large number of yarns Y 1 connected to the braid.

With the above, all steps of the composition step are completed. The composition steps of (a) to (nu) described above are examples, and are T-shaped by various steps including the moving / stopping order of the horizontal moving frame b1 and the fan-shaped moving member b17. The composition can be performed on the mandrel m, and is not limited to the above-described composition process.

In the above step (d), one end (1) of the mandrel m is removed from the mandrel mounting plate b34 ′, the mandrel m is rotated 180 degrees, and the other end (2) of the mandrel m is attached to the mandrel mounting plate b34 ′. The mandrel m can be easily attached to the mandrel mounting plate b34 'by the means for attaching the mandrel m to the mandrel mounting plate b34' described with reference to FIGS. 19 and 20. This process can be performed quickly.

Further, by disposing another mandrel device on the opposite side of the mandrel device Bm with the curved upper plate U interposed therebetween, it is possible to remove the mandrel m from the mandrel mounting plate b34 ′ of the mandrel device Bm. At the same time, it is also possible to attach the mandrel m to the mandrel mounting plate b34 'of the other mandrel device and continue the composition. By arranging two mandrel devices in this way, the mandrel m used in the next composition step can be attached to the mandrel device and prepared in advance.

In the above embodiments, the case where the composition is performed on the T-shaped mandrel m has been described, but the composition can be performed not only on the T-shaped mandrel m but also on the mandrel m having various shapes. It is a thing. When the rod-shaped mandrel m is used, a plurality of braider main bodies Bb may be arranged and multiple braids may be formed on the rod-shaped mandrel m.

The following is a list of operational effects achieved by the above-described embodiments of the present invention.

Since the composition point on the mandrel is located at a position where the axis of the bobbin placed on the bobbin carrier and the axis of the mandrel on which the composition is performed intersect, the yarn unwound from the bobbin bends. Therefore, the yarn can be smoothly unwound and the yarn is not subjected to excessive tension, so that the braid can be properly composed.

Since the composition point on the mandrel is located at the position where the axis of the bobbin placed on the bobbin carrier and the axis of the mandrel on which the composition is performed intersect, the braider is downsized, so that the operability of the braider is improved. It will improve and the installation area of the braider will decrease.

The curved orbit is arranged in a substantially cylindrical machine base with an axis horizontal and an opening on the side, and the composition point on the mandrel is substantially at the center of curvature of the curved orbit. Since it is positioned, it is possible to prevent the braider from becoming high, and it is possible to reduce the size of the braider.

Since the yarn unwound from the bobbin placed on the bobbin carrier and the middle yarn or the reinforcing yarn are both configured to be guided to the composition point on the mandrel, the bobbin An appropriate composition of the braid can be obtained because excessive tension is not applied to the yarn unwound from the bobbin placed on the carrier and the middle yarn or the reinforcing yarn.

Since the amount of yarn wound on the bobbin can be increased, the number of bobbin replacements can be reduced, and thus the productivity of the braider can be improved.

Since the bobbin carrier is configured to travel by the friction roller and the sliding friction roller, it is possible to prevent the generation of noise due to the backlash of the gear teeth.

By arranging the composition position stabilizing guide member, it is possible to regulate the swaying of the yarn swaying along with the lateral movement of the bobbin carrier traveling meandering along the track formed in the upper plate. In addition, the fluctuation of the composition point due to the movement of the mandrel can be suppressed, so that a stable composition can be realized without entanglement of the yarn to be composed in an irregular state near the composition point. It is possible to manufacture a braid in which the shape of the braid is uniform and stable. Further, by arranging the composition position stabilizing guide member, when the mandrel is moved after the composition is completed, a large number of yarns linked to the braid composed by the second composition position stabilizing guide member are bundled. Since this is possible, the yarn can be effectively cut by the cutting device.

Since the mandrel can be easily and quickly attached to the mandrel mounting plate, the productivity of the braider can be improved.

Since the cylindrical bobbin cover or the elastic plate is provided, when the bobbin carrier is inclined or positioned upside down, the yarn wound around the bobbin is pulled out or droops to be adjacent. Problems such as being entangled with the yarn wound around the bobbin or entangled with other members of the braider can be prevented.

Since the bobbin placed on the bobbin carrier and the bobbin wound with the middle yarn or the reinforcing yarn are shared, the bobbin and the bobbin wound with the middle yarn or the reinforcing yarn are used. It is not necessary to distinguish it from the bobbin that is mounted on the carrier.

Since the cutting device having the disc cutter for cutting the braid or the yarn connected to the braid which has been finished is provided, the braid or the yarn connected to the braid can be surely cut and the cutting time is shortened. be able to. Further, since the tension applied to the braid when the braid or the yarn connected to the braid is cut can be reduced, it is possible to prevent the shape of the braid from collapsing.

It is possible to suppress the increase of the braider and to reduce the size of the braider. Therefore, the operability of the braider is improved and the installation area of the braider is reduced.

By arranging the substantially cylindrical orbit so that its axis is horizontal and by arranging the mandrel inside the orbit, when starting the composition of the braid on the mandrel, the substantially cylindrical orbit is formed. The operation of bundling the ends of the yarns drawn out from the bobbins on the bobbin carriers arranged in the above position at a position outside the mandrel placement position and setting the mandrel between the yarns with the bundled ends. , It can be done in a comfortable posture with the worker standing.
