ものである。BACKGROUND TECHNOLOGY As a method for manufacturing this type of three-dimensional fabric,
For example, the one described in Japanese Patent Publication No. 61-1538 is known. In this device, a large number of carriers are arranged on a carrier fixed plate, a shaft thread is inserted through the central shaft of the carriers, a bobbin containing a entangled thread is arranged between the carriers, and the carrier receives the bobbin. A carrier arm that can be opened and closed for transferring the bobbin is provided, and the carrier arm is rotated around the carrier shaft to transfer the bobbin to an adjacent carrier, thereby moving the bobbin along an arbitrary path.
しかしながらこの発明においては、各キヤリヤ

ヤとの間でボビンの受渡しを行うことができる。
従つてボビンを受取るキヤリヤは、その受取りに
先立つてキヤリヤ腕をボビンの受取り位置に配置
しておかなければならない。 However, in this invention, each carrier can transfer bobbins to and from an adjacent carrier only at the position of the carrier arm.
Therefore, the carrier receiving the bobbin must have its carrier arm in the bobbin receiving position prior to receiving the bobbin.

ヤリヤ腕に衝突し、適正に作動させることができ
ない。 In addition, one carrier must rotate a predetermined angle from the time it receives the bobbin until it passes the bobbin to the next carrier, and in that rotation path, the carrier arm of the adjacent carrier is rotated toward the first carrier. Otherwise, the bobbin will collide with the carrier arm and cannot operate properly.

では足りず、当面の作動に全く関係のないキヤリ
ヤについてまで適切に制御しなければならず、プ
ログラムが極めて繁雑になる。 In this type of device, the moving path of the carrier is stored in advance in a computer, etc., and the bobbin is transferred and the carrier arm is rotated according to the program.In this program, the bobbin is transferred between specific carriers. It is not enough to control only the rotation of the carrier that grips the bobbin; it is also necessary to appropriately control the carrier, which is completely unrelated to the current operation, making the program extremely complicated.

ヤリヤの把持手段の開閉と、当面ボビンを把持し
ているキヤリヤの回転とのみを制御すればよく、
構造が簡単でしかもその制御プログラムが単純な
ものとなり、極めて好都合である。 Therefore, it has been devised that the gripping means in the carrier is made up of two disks that can be opened and closed in the vertical direction, and a gripping disk provided on the bobbin is held between the disks by pressure. According to this, the carrier has no directionality, and it is only necessary to control the opening and closing of the carrier gripping means involved in bobbin delivery and the rotation of the carrier that grips the bobbin for the time being.
The structure is simple and the control program is simple, which is extremely convenient.
発明が解決しようとする問題点
しかしながらこの種の把持手段を設けたもので

点がある。すなわちボビンの通過経路に沿つたキ
ヤリヤが閉じていると、ボビンがそのキヤリヤに
衝突して通過することができない。Problems to be Solved by the Invention However, in a device equipped with this type of gripping means, the gripping means has no directionality and can grip the bobbin in any direction, so the advantage is that the gripping means can be easily controlled. However, there is a drawback in that all carriers other than the carrier gripping the bobbin must have their gripping means in a released state. That is, if the carrier along the bobbin passage path is closed, the bobbin will collide with the carrier and cannot pass.
ところでこの種の装置を使用する場合、全ての
キヤリヤの把持手段を連動して、各キヤリヤにお
ける一の隣接するキヤリヤから次の隣接するキヤ
リヤまでの角度に相当する角度に亙つて往復して
回動せしめ、ボビンを移動せしめるべきキヤリヤ

回転させることを繰返し、ボビンを所望の経路に
沿つて移動させることが考えられている。この方
法によれば、把持手段の開閉のみを制御すれば足
りるので、制御手段をさらに簡単なものとするこ
とができる。 By the way, when this type of device is used, the gripping means of all the carriers are interlocked and each carrier is rotated back and forth through an angle corresponding to the angle from one adjacent carrier to the next adjacent carrier. Then, only the gripping means of the carrier that is to move the bobbin is in a gripping state only when the gripping means rotates in the direction in which the bobbin is to be moved, and in this gripping state, the carrier is rotated together with the bobbin gripping means repeatedly, and the bobbin is It is considered to move along a desired route. According to this method, since it is sufficient to control only the opening and closing of the gripping means, the control means can be further simplified.
しかしながらこの方法においては、把持手段が
ボビンの進行方向に回転するときにはそのボビン
を把持しているが、それが逆方向に回転するとき

ヤリヤの振動等によつて転倒し易く、織成を続け
ることができない。 However, in this method, when the gripping means rotates in the direction of movement of the bobbin, it grips the bobbin, but when it rotates in the opposite direction, the gripping means is in a released state, and the bobbin is not gripped by either carrier. Not done. Therefore, there is nothing to support the bobbin, and the bobbin falls off the gripping means, making it impossible to weave. Furthermore, even if the released bobbin is placed on a carrier support plate, it is likely to topple over due to the tension of the entangled yarn being pulled out from the bobbin, the vibration of the carrier, etc., and weaving cannot be continued.
また他の織成方法として、装置上に二以上の複
数のボビンを配置し、各ボビンをそれぞれ同一又
は異なる経路を辿つてキヤリヤの把持手段により
移動せしめ、三次元織物の織成速度を高めること
が考えられている。 Another weaving method involves arranging two or more bobbins on the device and moving each bobbin along the same or different paths by a carrier gripping means to increase the weaving speed of the three-dimensional fabric. is considered.
しかしながらこの場合、二以上のボビンがその
経路に従つて移動したとき、単一のキヤリヤの近
傍に集まることがある。例えばこの状態を第3図
に示す。 However, in this case, two or more bobbins may converge in the vicinity of a single carrier as they move along their path. For example, this state is shown in FIG.
第3図においてAはキヤリヤであつて、たて・
よこにマトリツクス状に配置されている。このマ
トリツクスにおけるX段Y列のキヤリヤAをAXY

ボビンCa,Cbの経路である。 In Figure 3, A is the carrier, and
They are arranged horizontally in a matrix. In this matrix, carrier A of X stage and Y column is A XY
It shall be displayed as . Curves Ba and Bb are the paths of the two bobbins Ca and Cb.
ある瞬間においてボビンCa,Cbは図示の位置
にあるとする。すなわちボビンCaはキヤリヤA31
に把持されて第一列のキヤリヤAを蛇行してお
り、ボビンCbはキヤリヤA42に把持されていて第
二列のキヤリヤAに沿つてボビンCaの後を追つ
て蛇行している。 Assume that bobbins Ca and Cb are at the positions shown in the figure at a certain moment. In other words, bobbin Ca is carrier A 31
The bobbin Cb is held by the carrier A 42 and is meandering along the carrier A of the second line, following the bobbin Ca.
この状態から続いてボビンCaはキヤリヤA31に
より、ボビンCbはキヤリヤA42によりそれぞれさ

ボビンCa,CbはキヤリヤA21及びキヤリヤA32に
より180゜回転せしめられた後、それぞれキヤリヤ
A11及びキヤリヤA22に受渡される。 Continuing from this state, the bobbin Ca is further rotated by 90 degrees by the carrier A 31 and the bobbin Cb by the carrier A 42 , and then delivered to the carriers A 21 and A 32 , respectively. Further, each bobbin Ca, Cb is rotated 180° by carrier A 21 and carrier A 32 , and then rotated by carrier A 21 and carrier A 32.
A 11 and delivered to carrier A 22 .
その後キヤリヤA11に把持されたボビンCaは
90゜回転せしめられた後キヤリヤA12に受渡される
が、ボビンCbはキヤリヤA22に把持されたままで
270゜回転せしめられる。そして当該ボビンCbが
キヤリヤA22の回転に伴つて当該キヤリヤA22と
キヤリヤA12との間を通過する頃にはキヤリヤ
A12の把持手段はボビンCaを把持して閉じてお
り、ボビンCbがここを通過することができない。 After that, the bobbin Ca held by carrier A 11 is
After being rotated 90 degrees, the bobbin Cb is transferred to carrier A 12 , but the bobbin Cb remains held by carrier A 22 .
It can be rotated 270°. By the time the bobbin Cb passes between the carrier A 22 and the carrier A 12 as the carrier A 22 rotates, the carrier
The gripping means A12 grips and closes the bobbin Ca, and the bobbin Cb cannot pass therethrough.
またボビンCbがキヤリヤA12とキヤリヤA22と
の間を通過しているときにキヤリヤA12の把持手
段が閉じると、当該把持手段によりボビンCbが
当該キヤリヤA12に把持されてしまい、動くこと
ができなくなる。 Furthermore, if the gripping means of the carrier A 12 closes while the bobbin Cb is passing between the carriers A 12 and A 22 , the bobbin Cb will be gripped by the carrier A 12 by the gripping means and will not move. become unable to do so.
このようなとき、本来ボビンを把持しているべ
きキヤリヤを一時的に解放して他のボビンの通過
を許さなければならないのであるが、前述のよう
にボビンを把持すべきキヤリヤをすべて解放する
と、前述のようにボビンが転落したり転倒して織
成を続けることができなくなる。 In such a case, it is necessary to temporarily release the carrier that should be holding the bobbin to allow another bobbin to pass, but as mentioned above, if all the carriers that should be holding the bobbin are released, As mentioned above, the bobbin falls or falls, making it impossible to continue weaving.
