18 is rotated counterclockwise in FIG. 18, the fan-shaped rack b22 screwed to the pinion b10 is driven, and the fan-shaped moving member b17 moves downward in FIG.

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. As a result, the endless belt b24 on the opposite side of the pulley b23 is pulled downward in FIG. 18 to rotate the endless belt b24 counterclockwise. Since the mandrel supporting and moving member b26 is fixed to the endless belt b24 at the point Z, the mandrel supporting and moving member b26 also moves downward in FIG. 18 by rotating the endless belt b24 in the counterclockwise direction. At this time, with the above configuration, the mandrel support moving member b26 moves twice as much as the moving amount of the pulley b23, and the mandrel support moving member 26 can move quickly.

Further, when the pinion b10 is rotated counterclockwise in FIG. 18 by the rotation of the motor b9 which can rotate forward and reverse, the fan-shaped rack b screwed to the pinion b10 is rotated.
22 is driven, the fan-shaped moving member b17 moves further downward in FIG. 18, and the mandrel supporting moving member b26 is
It is configured to be able to rotate to the lowermost position shown by the two-dot chain line in FIG. In order to move the mandrel support moving member b26 upward from the lowermost position shown by the two-dot chain line, the motor b9 that can be rotated forward and backward is rotated in reverse to rotate the pinion b10 clockwise in FIG. .

As described above, the mandrel m can be freely and two-dimensionally controlled in attitude by the horizontal movement of the horizontal moving frame b1 and the movement of the mandrel supporting and moving member b26. By arranging an appropriate actuator or the like on the mandrel mounting plate b34 'attached to the tip of the mandrel and attaching the mandrel m to an output shaft of the actuator or the like, the mandrel m can be three-dimensionally controlled. .

On the other hand, in the vicinity of the open end of the hollow mandrel m, a circumferential groove b39 in which the balls b37 and b37 'provided on the peg b35 can be fitted is formed, and the open end of the hollow mandrel m is formed. Is provided with a groove b40 into which a knob b38 arranged at the base of the peg b35 can be inserted. Therefore, the hollow mandrel m is inserted into the peg b35, and the balls b37 and b37 ′ provided on the peg b35 are inserted.
The mandrel m can be easily attached to the mandrel mounting plate b34 'by fitting the knob into a circumferential groove b39 formed near the opening end of the hollow mandrel m, and the knob protruding from the base of the peg b35 By inserting the b38 into the groove b40 formed in the opening end of the hollow mandrel m, the rotation of the mandrel m with respect to the mandrel mounting plate b34 'can be prevented.

FIG. 20 is a plan view of another embodiment showing the means for attaching the mandrel m to the mandrel mounting plate b34 '. In the attachment means shown in FIG. 20, pegs b41, b42 having circumferential grooves b41 ′, b42 ′ are attached to the end side of the mandrel m, and pegs b41, b42 are attached to the mandrel mounting plate b34 ′.

The ball b46 can be freely retracted from the recess b44 by the compression coil spring b45. It is configured. Note that b47 and b47 ′ are
These are knobs protruding from the bases of the pegs b41 and b42, respectively, and grooves b48 formed in the opening of the female member b43.
To prevent the mandrel m from rotating with respect to the mandrel mounting plate b34 '. Accordingly, the pegs b41 and b42 of the mandrel m are connected to the female member b4.
3 and the compression coil spring b4 is inserted into the circumferential grooves b41 'and b42' of the pegs b41 and b42.
The mandrel m can be easily attached to the mandrel mounting plate b34 'by fitting the ball b46 urged by 5 with the ball.

Next, referring to FIGS. 21 to 23 which are schematic plan views showing the composition steps, the T-shaped mandrel as shown in FIG. 18 is used as an example using the blader BR of the present invention. The process sequence for forming the braid on m will be described.

(A) First, with the driving of the blader body Bb stopped and the bobbin carrier C stopped running, the horizontal moving frame b1 is moved rightward in FIG. ) (Hereinafter simply referred to as “mandrel m”, and 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. Thereafter, the horizontal moving frame b1 is moved to the left in FIG. 2 and the fan-shaped moving member b17 is moved appropriately, so that the composition point P is set at one end (1) of the mandrel m as shown in FIG. (Note that, for convenience of description, an inverted triangle (▽) is attached to an end of the mandrel m attached to the mandrel mounting plate b34 ′).

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

(C) After the composition up 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.
By rotating the mandrel m as shown in FIG.
The state shown in (d) is set. From this state, the horizontal moving frame b1 is further moved rightward in FIG.
As shown in (e), the branch part m1 of the mandrel m is composed. Note that the fan-shaped moving member b17 can be moved at the same time by lowering the moving speed without stopping the movement of the horizontal moving frame b1.

(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. The traveling of the carrier C is stopped.
Then, as shown in FIG. 21 (f), one end (1) of the mandrel m is detached from the mandrel mounting plate b34 ', and the mandrel m is rotated by 180 degrees to be on the opposite side to the one end (1) of the mandrel m. 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 driving of the driving device D is restarted, the traveling of the bobbin carrier C is started, and the horizontal moving frame b1 is moved in FIG. Move to the left,
As shown in FIG. 22 (a), the mandrel m
Is formed.

(F) After the composition up to the joint j of the mandrel m, the driving device D is stopped to stop the travel of the bobbin carrier C and the movement of the horizontal moving frame b1 to stop the fan-shaped moving member b17. The mandrel m is moved downward at 18 and the mandrel m is rotated to the state shown in FIG. In this state, the driving device D is driven to restart the running of the bobbin carrier C to start the composition, and the fan-shaped moving member b17 is further moved downward to the state shown in FIG. 22 (c). The moving frame b1 is moved leftward in FIG. 2 to form the composition up to the end of the mandrel m as shown in FIG.

(G) As shown in FIG. 22 (d), after the composition up to the end of the mandrel m, the horizontal moving frame b
2 is moved rightward in FIG. 2 to form a composition toward the joint j of the mandrel m, as shown in FIG.

(H) With the composition advanced to the vicinity of the joint j of the mandrel m, the fan-shaped moving member b17 is moved upward while the horizontal moving frame b1 is moved rightward in FIG. b), the movement of the horizontal moving frame b1 is stopped in this state, and the driving device D
To stop the travel of the bin carrier C.

Next, the fan-shaped moving member b17 is moved downward to bring the mandrel m to the state shown in FIG. Thereafter, the driving of the driving device D is resumed, the traveling of the bobbin carrier C is started, and the horizontal moving frame b1 is moved rightward in FIG.
The composition of the joint j of the mandrel m is performed as shown in FIG.

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

(L) After the composition of the mandrel m is completed, the driving device D is stopped to stop the travel of the bin carrier C.

(E) Next, the horizontal moving frame b1 is largely moved rightward in FIG. 2 to move the mandrel m to a position beyond the disk cutter s12 of the cutting device S.
From this state, the motor s3 is rotated as described above to rotate the disk cutter s12 at a high speed. On the other hand, the speed reducer s2
With the rotation of the output shaft s6, which is rotated at a low speed by the motor s3, the lever s17 is rotated from the standby position shown by the two-dot chain line in FIG. 16 to the operating position shown by the solid line. 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. With the rotation of the lever s9, a number of yarns continuous with the braid that is bent and bound by the second composition position stabilizing guide member g2 into the horizontal guide groove s14 ′ of the guide member s14 attached to the distal end of the lever s9. The yarn Y is guided, and is brought into contact with the disk cutter s12 attached to the pulley s13 and rotating at a high speed to cut a large number of yarns Y connected to the braid.

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

In the above step (d), the mandrel m
Is removed from the mandrel mounting plate b34 ', and the mandrel m is rotated by 180 degrees so that the mandrel m
When the other end (2) of the mandrel is attached to the mandrel attaching plate b34 ', the mandrel attaching plate b34' described with reference to FIGS. Since the mandrel m can be attached to b34 ', this step can be performed quickly.

Further, by disposing another mandrel device on the opposite side of the mandrel device Bm across the curved upper plate U, it is possible to remove the mandrel m from the mandrel mounting plate b34 'of the mandrel device Bm. At the same time, the mandrel m may be attached to the mandrel mounting plate b34 'of the other mandrel device to continue the composition. Thus, the mandrel device 2
The mandrel m to be used in the next composition step can be attached to the mandrel device and prepared in advance by arranging the mandrel m.

In the above embodiment, the case where the composition is performed on the T-shaped mandrel m has been described. However, the composition can be performed on the mandrel m having various shapes without being limited to the T-shaped mandrel m. is there. When the rod-shaped mandrel m is used, a plurality of braider bodies Bb may be arranged to form multiple braids on the rod-shaped mandrel m.

The operation and effect of the embodiment of the present invention will be described below.

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 where the composition is performed intersect, the yarn unwound from the bobbin may be bent. Therefore, the yarn can be smoothly unwound and no excessive tension is applied to the yarn, so that an appropriate composition of the braid can be achieved.

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 where the composition is performed intersect, the size of the blader is reduced, so that the operability of the blader is improved. The installation area of the blader is reduced with the improvement.

A curved orbit is arranged in a substantially cylindrical machine base having a horizontal axis and an opening at the side, and
Since the composition point on the mandrel is substantially located at the center of curvature of the curved orbit, it is possible to prevent the height of the blader from increasing, and to realize the downsizing of the blader.

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 points on the mandrel, the bobbin carrier is used. Since an excessive tension is not applied to the thread unwound from the bobbin placed on the inner thread and the middle thread or the reinforcing thread, an appropriate composition of the braid can be performed.

Since the amount of yarn wound on the bobbin can be increased, the number of times of bobbin replacement is reduced, and therefore,
The productivity of the blader can be improved.

Since the bobbin carrier is made to run 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 sway of the yarn swaying with the lateral movement of the bobbin carrier running meandering along the track formed on the upper plate. And fluctuation of the composition point due to the movement of the mandrel can be suppressed.
A stable composition can be realized without the yarn to be composed being entangled in an irregular state in the vicinity of the composition point, so that a braid having a uniform and stable shape can be manufactured. Further, by disposing the composition position stabilizing guide member, when the mandrel is moved after the composition is completed, it is possible to bundle a large number of yarns connected to the braid formed by the second composition position stabilizing guide member. Since it is possible, the cutting device can effectively cut the yarn.

Since the mandrel can be easily and quickly attached to the mandrel mounting plate, the productivity of the blader 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 on the bobbin is pulled out or hangs down and is adjacent to the bobbin carrier. It is possible to prevent troubles such as entanglement with the yarn wound on the bobbin or entanglement with other members of the blader.

Since the bobbin placed on the bobbin carrier and the bobbin around which the middle or reinforcing thread is wound are shared, the bobbin around which the middle or reinforcing thread is wound and the bobbin carrier are used. There is no need to distinguish the bobbin from being placed on the bobbin.

Since the cutting device having the disk cutter for cutting the braid or the thread connected to the braid having completed the composition is provided, the braid or the thread connected to the braid can be reliably cut and the cutting time can be shortened. Can be. In addition, since the tension applied to the yarn at the time of cutting the braid or the yarn connected to the braid can be reduced, it is possible to prevent the shape of the braid from collapsing.

[0099]

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

Since the yarn unwound from the bobbin does not bend, the yarn can be smoothly unwound, and excessive tension is not applied to the yarn. it can.

The height of the blade can be suppressed and the size of the blade can be reduced, so that the operability of the blade can be improved and the installation area of the blade can be reduced.

The substantially cylindrical orbit is arranged so that its axis is horizontal, and the mandrel is arranged inside the orbit, so that when the composition of the braid is started on the mandrel, the substantially cylindrical orbit is formed. The work of bundling the leading end of the thread pulled out from the bobbin on each placed bobbin carrier at a position deviating from the arrangement position of the mandrel, and setting the mandrel between the thread bundles with the leading end bundled, It can be performed in a comfortable posture with the worker standing.
