Description

  The present invention relates to a braiding machine for composing braids and a composition method thereof, and particularly relates to the composition of a braided braid.

  Conventionally, in this seed braiding machine, as shown in Patent Document 1 below, a plurality of horn disks that rotate in opposite directions are arranged circumferentially, and a plurality of carriers including a thread bobbin and a buffer are provided. Passing between horn discs. In addition, the braiding machine body is provided with a substantially horizontal plate. In the plate, annular grooves are formed along the outer periphery of each horn disk, and a closed path is formed in which the grooves communicate with each other. A supply section for supplying an inner core wire from the inner side of the closed path is provided inside the closed path. When a pair of carriers moving along the closed path is transferred between the horn disks, the yarn is crossed on the outer periphery of the inner core line. The crossed yarn is wound up together with the inner core wire to form a braid with the inner core wire.

  In the braiding machine, the closed path can be switched between a single closed path and two closed paths obtained by dividing the single closed path into left and right. Inside the left and right closed paths, there are two left and right supply units that supply the inner core wire for each of the left and right closed paths, and the yarns from each carrier moving along a single closed path are combined into one. One braid passing through the two internal core wires is formed by crossing the outer periphery of the internal core wires. On the other hand, two braids that individually pass through the inner core wire are formed by individually crossing the yarns from the carriers that move every two closed paths on the outer periphery of the inner core wire. In other words, by switching a single closed path to the left and right closed paths, one braid can be branched into two braids, or two braids can be combined into one braid. .

By the way, in the said conventional thing, when switching to a single closed path | route and composing one braid, the state which put together the two internal core wires, ie, the state which the outer periphery of each other internal core wire contact | connected And the thread crosses the outer periphery. For this reason, when switching to a single closed path or two closed paths and branching from one braid to two braids, or when combining two braids into a single braid, A hole is opened between the two braids and the two braids, that is, in the branch portion, and the inner core wire is exposed from the hole.
In addition, since the two internal cores passed through one braid run parallel to each other inside the braid without being individually restrained, the internal cores are likely to be misaligned inside the braid. .

  The present invention has been made in view of such a point, and the object of the present invention is that even if the closed path is switched, it can be reliably closed without making a hole in the branch portion, and the inside of one braid An object of the present invention is to provide a braiding machine and a composition method thereof that can reliably prevent displacement between internal core wires.

  In order to achieve the above object, the present invention comprises a plurality of carriers for feeding out a yarn and a plurality of horn disks for rotating the respective carriers, and each of the carriers is delivered by passing the carriers between the horn disks. Assuming a braiding machine that crosses the yarn from each carrier at the outer periphery of the inner core wire and winds the crossed yarns together with the inner core wire to form a braid, the outer periphery of each horn disk is provided on a plate provided on the braiding machine body. A plurality of closed paths are formed by connecting the grooves to each other. Further, each carrier is moved along each closed path for each closed path, while each of the menopauses crossing from one closed path to the other closed path at the intersection of the closed paths intersecting each other. It is configured to move across the road. Furthermore, a switching means is provided at the intersection of each closed path, and a plurality of single braids separated for each closed path by restricting the movement of each carrier from the one closed path to the other closed path. By combining the regulated position and the movement of each carrier from one closed path that intersects at the intersection to the other closed path, a plurality of braids are combined while being separated by the intersection at the intersection Switch to an allowable position for composing a single united braid. And, the switching means is characterized in that it switches to an allowable position when each single braid is composed to a required length, and to a restricting position when the united braid is composed to a necessary length. .

  Further, a winding speed at which the yarn from each carrier is wound together with the inner core wire when the switching means is switched to the restriction position, and a yarn from each carrier when the switching means is switched to the allowable position. It is preferable to change at least one of the winding speeds to be wound together so as to change the yarn density on the outer periphery of the inner core wire.

  In addition, at the intersection of each closed path, an intersection path is formed in which two grooves for each closed path intersect each other, and between each groove of the intersection path and the groove of each closed path communicating therewith In addition, there is provided restriction means for restricting carrier movement between each closed path and the intersection path when the switching means switches to the allowable position. Preferably, at the time of restriction by the restriction means, each carrier is caused to make at least a half turn in the intersection path in a state where movement of each carrier in the closed path is stopped.

  Further, when regulating by the regulating means, the winding speed for winding the yarn from each carrier moving along the crossing path together with the inner core wire is zero or a reverse direction in which the yarn is wound together with the inner core wire at a very low speed close to zero. It is preferable to set so as to act on.

  On the other hand, a plurality of carriers for feeding out the yarn and a plurality of horn disks for rotating the respective carriers, and by passing each of the carriers between the respective horn disks, the yarns from the respective carriers are internally As a composition method of the braiding machine that crosses the outer periphery of the core wire and winds the crossed yarns together with the inner core wire to compose the braid, the annular grooves along the outer peripheral portion of each horn disk in the plate of the braiding machine body are formed. A single braid composition step of composing a plurality of single braids each having an inner core by moving each carrier along each of the closed paths communicated with each other, and between the closed paths Crossing each closed path while crossing each carrier from one closed path to the other closed path A combined braid composition step of composing a single united braid united into a plurality of single braids having the inner core wire by moving them, and a length required for each single braid by the single braid composition step A switching step of switching to the single braid composition step when the combined braid composition step is composed to a required length by the combined braid composition step. It is characterized by that.

  Further, at least one of a winding speed for winding the yarn from each carrier together with the inner core wire in the single braid composition step and a winding speed for winding the yarn from each carrier together with the internal core wire in the combined braid composition step. It is preferable that the yarn density on the outer periphery of the inner core wire is changed.

  In addition, when the single braid composition step or the combined braid composition step is switched in the switching step, each menopause is performed at the intersection of each closed path prior to the execution of the single braid composition step or the combined braid composition step. A crossing step of causing each carrier on the crossing path where two grooves for each road cross each other to travel at least 1/2 in the crossing path in a state where movement of each carrier on each closed path adjacent to the crossing path is regulated Is preferably performed.

  Further, in the crossing step, the winding speed for winding the yarn from each carrier moving along the crossing path together with the inner core wire is set in the reverse direction so that the yarn is rewound together with the inner core wire at zero or a very low speed near zero. It is preferable to do.

According to the braiding machine according to the present invention, the switching means provided at the intersection of each closed path includes a restricting position for composing a plurality of single braids separated for each closed path, and from one closed path to the other menopause. By switching each braid to a permissible position that composes a single united braid united while merging multiple braids while allowing movement of each carrier to the road, The branch part of one united braid and a plurality of single braids is closed by the thread | cross which cross | intersects in an intersection part, and exposure of the internal core wire in a branch part can be prevented reliably.
Moreover, the composition of the single united braid united into a single united united braid while being divided into a plurality of single braids can reliably prevent the positional deviation between the inner core wires within the united braid.

  Further, by changing at least one of the winding speed when the switching means is switched to the restriction position and the winding speed when the switching means is switched to the allowable position, the yarn density on the outer periphery of the inner core wire is changed. The yarn density can be increased and strengthened according to the usage pattern of the united braid and each single braid, and the yarn density can be increased near the branching portion to strengthen the branching portion.

  In addition, by moving each carrier of the crossing path so that the movement of each carrier in each closed path is stopped at least 1/2 turn in the crossing path, a single united braid and a plurality of The branch portion with the single braid is reinforced by the yarn intersecting in the crossing path, and the branch portion can be effectively strengthened.

  Furthermore, when regulating by the regulating means, that is, when each carrier is moved only on the crossing path, the winding speed is set to act in the reverse direction of rewinding at zero or a very low speed close to zero. And the yarn density at the branch portion between each individual braid increases and the branch portion can be effectively strengthened.

  On the other hand, according to the composition method of the braiding machine according to the present invention, when each single braid is composed to the required length by the single braid composition step, the combined braid composition step is combined with the combined braid composition step. By switching to the single braid composition process when it is composed to the required length, the branch part of each single braid and the combined braid is closed with the yarn that intersects at the intersection, ensuring the internal core wire is exposed at the branch It is possible to form a braid that can prevent the positional deviation of the inner core wires in the single united braid united together while being separated into a plurality of single braids.

  Further, by changing at least one of the winding speed in the single braid composition step and the winding speed in the combined braid composition step, and changing the yarn density on the outer periphery of the inner core wire, the combined braid and each single braid , And a united braid that can be strengthened near the branch portion and each individual braid.

  In addition, prior to the execution of the single braid composition process or the combined braid composition process switched in the switching process, each carrier of the cross path, in a state where the movement of each carrier in each closed path is stopped, in the cross path By executing the crossing process of moving each carrier so as to make at least a 1/2 turn, it is effective to reinforce the branch part of a single united braid and a plurality of single braids with a thread that crosses the crossing path. A braid that can be reinforced can be formed.

  Furthermore, by setting the winding speed in the crossing process to be applied in the reverse direction of rewinding at zero or a very low speed close to zero, the branch portion is increased by the yarn density increased at the branch portion of the combined braid and each individual braid. The braid which can reinforce effectively can be composed.

At this time, the base ends of the second and third levers 536a and 536b rotate around the center of the driven gear 531 to displace the tip positions of the second and third levers 536a and 536b, and swing the second arms 538a. The upper and lower first arms 537a are rotated together with the left and right penetrating shafts 537L and 537R, whereby the pair of upper and lower second advancing / retreating members 52 are retracted from the respective through grooves 31 of the intersecting portions 35 and 36.
As a result, the carriers 2 move along the left and right closed paths 33L, 33R, 34L, 34R without intersecting at the intersecting portions 35, 36, and the outer periphery of the inner core wire 20 is individually crossed and covered on the left and right. Two single braids A are composed.

Next, in the united braid composition step of composing a single united braid B that combines the two single braids A having the inner core wire 20, the closed paths 33 and 34 of the upper and lower plates 3A and 3B are combined. The switching means 5 is switched to the allowable position so as to allow communication between the through grooves 31 at the intersections 35 and 36.
That is, the pulse motor 530 is rotated to rotate the driven shaft 531 a by 180 °, and the first lever 532 is rotated together with the driven gear 531. By this rotation, the upper and lower first advance / retreat members 51 are retracted to the retracted position (position shown in FIG. 8). This allows communication between the through grooves 31 of the left closed paths 33L and 34L and the through grooves 31 of the right closed paths 33R and 34R that are adjacent to each other at the intersections 35 and 36. At this time, the tip positions of the second and third levers 536a and 536b are displaced by the rotation of the second and third levers 536a and 536b, and the upper and lower first arms 537a are passed through the left and right first arms 538a by swinging the second arms 538a. By rotating together with the shafts 537L and 537R, a pair of upper and lower second advancing and retracting members 52 are advanced into the respective through grooves 31 of the intersecting portions 35 and 36.
As a result, the carriers 2 cross each other at the intersecting portions 35 and 36 and move along the long closed paths 33 and 34 in the shape of a figure 8, and the figure 22 is crossed on the outer periphery of the inner core wire 20 on the left and right. A single united braid B coated in a shape is formed.

  In the switching process of switching from the single braid composition process to the combined braid composition process or from the combined braid composition process to the single braid composition process, as shown in FIG. 13 (a), each single braid A has a required length by the single braid composition process. As shown in FIG. 13B, the combined braid composition process is switched to the single braid composition process when the combined braid B is formed to a required length by the combined braid composition process. Switching by this switching process is executed by switching to the restricted position or the allowable position by the switching means 5. At this time, the winding speed for winding the yarn 22 from the carrier 2 moving along the respective closed paths 33 and 34 by the winding pulley 6 together with the inner core wire 20 is higher than the winding speed of the winding pulley 6 in the single braid composition step. Also, the yarn density at the outer periphery of the inner core wire 20 is changed so as to be slower.

Furthermore, when switching to the single braid composition process or the combined braid composition process in the switching process, the crossing process is executed prior to the execution of the single braid composition process or the combined braid composition process.
In this intersecting step, the means for restricting the communication between the respective through grooves 31 at the intersecting portions 32 between the respective through grooves 31 of the intersecting paths 37 and 38 and the respective through grooves 31 of the left and right closed paths 33 and 34 intersecting with the above. It is regulated by 8. That is, the first lever 532 is rotated together with the driven gear 531 by the rotation of the pulse motor 530 of each regulating means 8 and the upper and lower first advancing / retracting members 51 are advanced to the advanced position, so that they are adjacent to the intersection paths 37 and 38. The communication between the respective through grooves 31 at the intersection 32 is restricted.

  In the crossing step, each horn disk 4a, 4h, 4i, 4p in the crossing paths 37, 38 is replaced with another horn disk 4b, 4c, 4d, 4e, 4f, in which each closed path 33L, 33R, 34L, 34R remains. With the rotations of 4g, 4j, 4k, 4l, 4m, 4n, and 4o stopped, the carriers 2 are rotated in the crossing paths 37 and 38 so as to make a half turn in the crossing paths 37 and 38. The yarn 22 from each carrier 2 moving on the cross paths 37 and 38 is composed of two single braids A composed in the single braid composition step and a single united braid B composed in the combined braid composition step. Cross at the bifurcation 27 of. At this time, the winding speed at which the yarn 22 from each carrier 2 is wound together with the inner core wire 20 by the winding pulley 6 is zero or a very low speed close to zero, and the yarn 22 is wound back together with the inner core wire 20 in the reverse direction. It is set to be.

  In this embodiment, when each single braid A is composed to the required length by the single braid composition step, when the combined braid composition step is composed to the necessary length by the combined braid composition step By switching to the single braid composition step by the switching means 5 respectively, the branch portion 27 between the single united braid B and the two single braids A is closed by the yarn 22 intersecting at the intersecting portions 35 and 36, and branched. The exposure of the inner core wire 20 at the portion 27 can be reliably prevented.

  In addition, since the single single braid A is combined into a single united braid B that is united while being separated, positional displacement of the inner core wires 20 in the united braid B can be reliably prevented.

  Moreover, the winding speed by the winding pulley 6 in the combined braid composition process is more dependent on the difference in the winding length of the closed path in each process than the winding speed by the winding pulley 6 in the single braid composition process. The yarn density of the combined braid B can be increased and strengthened by changing the yarn density at the outer periphery of the inner core wire 20 by changing the yarn density so as to be slower.

  Further, prior to the execution of the single braid composition process or the combined braid composition process switched in the switching process, by executing the crossing process in which each carrier 2 is circulated 1/2 in the crossing paths 37 and 38, a single unity The branch portion 27 between the braid B and the two single braids A is reinforced by the yarns 22 that intersect at the intersection paths 37 and 38, and the branch portion 27 can be effectively strengthened.

  Furthermore, by setting the winding speed by the winding pulley 6 in the crossing step to zero or a very low speed close to zero in the reverse direction, the yarn density at the branching portion 27 increases, and the branching portion 27 becomes more effective. Can be strengthened.

  The present invention is not limited to the above-described embodiment, and can be implemented without departing from the gist of the present invention. For example, in the above-described embodiment, the left and right closed paths 33L, 33R, 34L, and 34R that alternately repeat the inner and outer turns of each through groove 31 at the left and right positions of the upper plate 3A and the lower plate 3B are provided. Although formed, as shown in FIG. 14 (a), each of the left and right positions of the upper plate 3A and the lower plate (not shown) has two types of left and right that alternately repeat the inner and outer turns of each through groove 31 respectively. Two or more closed paths (not shown) may be formed on each of the left and right sides.

(Not shown) may be formed two or more before and after. In this case, of the two closed paths formed before and after, the switching means 5 is provided at the intersections 35 and 36 between the front closed path and the rear closed path, and the intersections 35 and 36 intersect. A restricting means (not shown) is provided at the intersection 32 of each through groove 31 of the path (not shown) and each through groove 31 intersecting with this.

  Moreover, in the said embodiment, although the winding speed of the winding pulley 6 in a united braid composition process was changed so that it might become slower than the winding speed of the winding pulley 6 in a single braid composition process, single braid composition Similarly, the winding speed of the winding pulley in the process is changed so as to be slowed to increase the yarn density at the outer periphery of the inner core wire of each single braid, or in the vicinity of the branch portion in the combined braid composition process and the single braid composition process When approaching, the winding speed of the winding pulley 6 may be changed so as to be slower than when it is not near the branch portion, and the yarn density at the outer periphery of the inner core wire near the branch portion may be increased. In this case, the yarn density of each single braid can be increased and strengthened, while reinforcement in the vicinity of the branch portion can be performed.

  Further, in the above-described embodiment, the closed paths 33L, 33R, 34L, and 34R are formed in the upper plate 3A and the lower plate 3B, respectively, but the closed path may be formed only in the upper plate. A single guiding portion for guiding the carrier along each closed path of the upper plate is provided on the lower surface of the slide base of the carrier.

  In the embodiment, the through groove 31 penetrating the upper and lower plates 3A and 3B is provided. However, a groove recessed downward may be formed only in the lower plate. A carrier moves by being guided by a single guiding portion in a closed path communicating with each other.
