Description

【0001】
【発明が属する技術分野】
本発明は、織機の電動耳組装置の制御方法に関する。
【0002】
【従来の技術】
特許第2933889号公報の技術は、ひねり耳形成装置を用いたひねり耳形成方法を開示している。そのひねり耳形成方法は、図1に示すように、2本のひねり糸(耳糸)2、3を導く2つの目孔(案内部)5、6を有する、ひねりディスク(回転部材)4を備えたひねり耳形成装置1において、ひねりディスク4を一方向に回転させ、ついで、ひねりディスク4を反対方向に回転させることによって、一方向の回転によって引き起こされるひねり糸2、3のひねり、あるいは絡みつきを反対方向の回転によって相殺するようにしている。このようにして、緯糸7は、2本のひねり糸(耳糸)2、3のひねりの間で保持される。
【0003】
また、特表平11−501999号公報の技術は、回転子(回転部材)に2つのからみ糸を通す腕を設けたレノ耳を形成する装置において、回転子を一方向へ特定数の回転をさせた後に、回転子の回転方向を反転され、逆の回転方向へ回転することによって、からみ糸の撚りを解消できるようにしている。
【0004】
【発明が解決しようとする課題】
上記の従来の技術によると、ひねりディスクあるいは回転子などの回転部材の反転直前に挿入された耳部分の緯糸と、それに隣り合う耳部分の緯糸との間に、耳糸によるねじれがなく、単に交差している状態になっていた。このため耳部分の緯糸の緩みが発生しやすく、これが織物の品質に悪影響を及ぼす、という欠点がある。
【0005】
図2は、一例として、前記の特許第2933889号公報の耳形成方法によって、100ピック目に反対方向の回転として、右方向に1回転反転させるときの上記の欠点の状況を示している。
【0006】
図2の(1)で、ひねりディスク4が左方向に半回転回転し終わった状態(100ピック目)で、ひねりディスク4を右方向に半回転反転させる。図2の(2)で、さらに、ひねりディスク4を右方向に半回転回転させる。図2の(1)および(2)の回転は、連続で行われる。図2の(3)で、つぎの緯糸7がひねり糸2、3の開口内に向かって飛走する。
【0007】
図2の(4)で、緯糸7がひねり糸2、3の開口内を通過した後、ひねりディスク4を右方向に半回転回転させる。ここからひねりディスク4を常に右方向に回転させる。図2の(5)以降に、(3)(4)を繰り返す。この図2の(5)において、100ピックの前後(円の内部)で、ひねり糸2、3が互いに絡んでおらず、緯糸7が緩みやすくなり、これが織物の品質に悪影響を及ぼすことになる。
【0008】
したがって、本発明の目的は、この種の耳組装置で、耳形成を行う際に、耳部分の緯糸の緩みを防止できるようにすることである。
【0009】
【課題を解決するための手段】
上記目的のもとに、本発明は、電動耳組装置において、耳糸を案内する回転部材の反転によって、耳部分の隣り合う緯糸の間に、緯糸が挿入されていないねじれを形成することにより緯糸の緩みを防止している。
【0010】
具体的に記載すれば、請求項1の電動耳組装置の制御方法は、少なくとも2本の耳糸が通過する一対の案内部を有した回転部材を一方向に回転させ、続いて他方向に回転させることにより耳形成を行う電動耳組装置において、回転部材が一方向から他方向に反転する際に、その反転動作によって緯糸が挿入されていないねじれを形成するようにしている。
【0011】
また、請求項2で、回転部材の反転時の回転回数を任意に設定可能とし、さらに、請求項3で、回転部材の反転時の回転回数と反転速度とを相対的に変化させている。
【0012】
【発明の実施の形態】
図3は、本発明の制御方法を実施するための電動耳組装置10を示す。この電動耳組装置10は、回転部材8、駆動装置9および制御装置11を具備する。
【0013】
回転部材8は、2本の耳糸12、13を導く2つの目孔による案内部14、15を有している。2本の耳糸12、13は、それぞれボビン16、17から引き出され、ガイド18を経て、回転部材8の案内部14、15を通り、互いに絡みあって、緯糸7の端部を保持する。
【0014】
回転部材8は、2本の耳糸12、13のひねり運動を妨げないように、回転部材8の外周側から駆動装置9のローラやベルトなどの回転伝達手段19により駆動される。駆動装置9は、回転方向、回転回数および回転速度の転換可能な駆動モータ20を含み、制御装置11により制御される。制御装置11は、入力器22からの設定データをもとに織機の主軸21と同期した状態で、本発明の電動耳組装置の制御方法にもとづいて、駆動装置9内の駆動モータ20の回転方向、回転回数および回転速度を制御する。
【0015】
制御装置11は、複数ピックにおいて回転部材8を一方向に所定の回転回数ずつ回転させ緯糸を把持し、一旦反転し続いて複数ピックにおいて回転部材8を他方向に所定の回転回数ずつ回転させ緯糸を把持することを繰り返すことを行う。詳細には、本発明の電動耳組装置の制御方法により、駆動装置9の内の駆動モータ20を駆動し、各ピックで回転部材8を一方向に所定の回転回数ずつ回転させ緯糸を把持し、一旦反転して、続いて所定のピック数ごとに、回転部材8を他方向に所定の回転回数ずつ回転させ緯糸を把持することを繰り返すことにより、耳形成を行う過程で、回転方向の反転する際に、その反転動作によって、緯糸7が挿入されていないねじれを形成する。
【0016】
つぎに、図4は、本発明の電動耳組装置の制御方法による耳形成過程、および耳形成過程でのピック数と回転回数との対応関係の表を示す。図4で、耳形成の制御は、回転部材8の反転時の回転回数を1回転に設定し、100ピック目の緯糸7が耳糸12、13の開口内を通過した直後に、回転部材8の回転方向の反転を行う。この図4の表で、回転部材8の回転方向は、100ピック単位で反転するものとし、回転部材8の回転の左方向は+、右方向は−とする。なお、この例で製繊中に、回転部材8の回転速度(回転数)は、一定(固定)とする。
【0017】
図4の表において、1〜99ピックの期間で、回転部材8は、ピック間毎に左方向(+)に半回転回転するから、2本の耳糸12、13は、ねじれを形成しながら、緯糸7の端部を保持する。100ピック目に緯糸7が耳糸12、13と交差した後に、回転部材8は、右方向(−)に1回転回転するから、100ピック目と101ピック目との間で、2本の耳糸12、13は、円内のように、緯糸7が挿入されていない−1回転のねじれを形成する。これにより、100ピック目の緯糸7のゆるみが防止できる。
【0018】
このあと、101〜199ピックの期間で、回転部材8は、ピック間毎に右方向(−)に半回転回転するから、2本の耳糸12、13は、ねじれを形成しながら、緯糸7の端部を保持する。200ピック目に緯糸7が耳糸12、13と交差した後に、回転部材8は、左方向(+)に1回転回転するから、200ピック目と201ピック目との間で、2本の耳糸12、13は、緯糸7が挿入されていない+1回転のねじれを形成する。これによって、200ピック目の緯糸のゆるみが防止できる。このように、回転部材8の回転方向は、100ピック単位で反転し、1回転のねじれを形成する。
【0019】
図5は、本発明の電動耳組装置の制御方法による耳形成過程、および耳形成過程でのピック数と回転回数との対応関係の表を示す。図5で、耳形成の制御は、回転部材8の反転時の回転回数を1回転半に設定し、100ピック目で緯糸7が耳糸12、13の開口内を通過し、回転部材8の回転が終了した後に、反転を行う。この図5の表でも、回転部材8の回転方向は、100ピック単位で反転するものとし、回転の左方向は+、右方向は−とする。なお、この例で製繊中に、回転速度(回転数)は、一定(固定)とする。
【0020】
図5の表において、1〜99ピックの期間で、回転部材8は、ピック間毎に左方向(+)に半回転回転するから、2本の耳糸12、13は、ねじれを形成しながら、緯糸7の端部を保持する。100ピック目に緯糸7が耳糸12、13と交差した後に、回転部材8は、左方向(+)に半回転回転した後、右方向(−)に1回転半回転するから、100ピック目と101ピック目との間で、2本の耳糸12、13は、緯糸7が挿入されていない(−1回転半+半回転)=−1回転のねじれを形成する。これによって、100ピック目の緯糸7のゆるみが防止できる。
【0021】
このあと、101〜199ピックの期間で、回転部材8は、ピック間毎に右方向(−)に半回転回転するから、2本の耳糸12、13は、ねじれを形成しながら、緯糸7の端部を保持する。200ピック目に緯糸7が耳糸12、13と交差した後に、回転部材8は、左方向(−)に半回転回転した後、左方向(+)に1回転半回転するから、200ピック目と201ピック目との間で、2本の耳糸12、13は、緯糸7が挿入されていない+1回転のねじれを形成する。これにより、200ピック目の緯糸7のゆるみが防止できる。このように、回転部材8の回転方向は、100ピック単位の周期で反転し、1回転のねじれを形成する。
【0022】
この場合緯糸7が挿入されていないねじれは、反転する過程において一旦口出し状態(ねじれがない状態)を経て、さらに少なくとも1回転させて開口状態とすることにより形成される。
【0023】
以上のように、図4および図5の例によれば、回転部材8の反転動作によって緯糸7が挿入されていないねじれを形成することにより、耳糸12、13が互いに絡まり、耳部分で隣り合う緯糸7の間に緯糸7が挿入されていないねじれが形成される。このため、緯糸7に絡んでいる互いの耳糸12、13を締める効果が向上する。よって緯糸7の緩みを防止することができ、織物の品質向上に大きく頁献することができる。
【0024】
また、図4の例によれば、図5の例に比べて半回転小さい回転回数でねじれを形成できるため、回転部材8の回転時の時間短縮など製織に対する効率が良くなる。
【0025】
さらに、図6は、記憶機能を備えた制御装置11を用いて、回転部材8の反転時の回転回数を任意に設定可能とする例を示す。制御装置11は、内部メモリの記憶機能により、織機の主軸21の回転数(織機の回転速度)と回転部材8の反転時の回転回数との対応関係を記憶できるようになっている。
【0026】
そこで、作業員は、入力器22を操作して、例えば主軸21の回転数=800rpmの時、反転時の回転回数=1回転半、また、主軸21の回転数=1000rpmの時、反転時の回転回数=1回転と設定する。
【0027】
このように設定すると、製織中に織機の主軸21の回転数が800rpmから1000rpmに変更されると、回転部材8の反転時の回転回数は、1回転半から1回転に変更される。この結果、主軸回転数800rpmのとき、締め具合の強化のために、ねじれは円内に見られるように2回形成される。
【0028】
回転部材8の反転時の回転回数の制御には、下記の2通りがある。(1)反転時の回転回数を任意に設定し、製織中はその回転回数に固定とする。これは、前記の図4および図5の例である。(2)糸種、織機の主軸21の回転数などの少なくとも1つの条件に対して、複数の回転回数を任意に設定し、製織中に糸種、織機の主軸21の回転数などが変更されたときは、その都度、条件に対応した回転回数に随時変更される。これは、前記の図6の例である。
【0029】
このように、回転部材8の反転時の回転回数を任意に設定可能とすることにより、耳糸のねじれの絡み具合を調整することができ、また、糸種、織機の主軸21の回転数などの少なくとも1つの条件ごとに、複数の回転回数を任意に設定可能とすれば、条件に対応する的確なねじれを形成することができる。
【0030】
回転部材8の反転時の回転回数を半回転の整数倍単位とし、n×半回転に設定可能としてもよい。もちろん、2本の耳糸12、13のあいだで、ねじれが形成可能な最小回転回数を設定可能な最小値とする。設定可能な最小値は、図4の制御では1回転(半回転+半回転)とし、また図5の制御では、1回転半(1回転+半回転)とする。通常、電動耳組装置10の回転部材8は半回転単位で回転するため、半回転単位で設定できれば、設定自体が簡素化される。例えば反転時の回転回数設定用として、入力器22に「▲」「▼」ボタンを設け、一方の「▲」ボタンを押すと、反転時の回転回数が半回転単位で増加し、他方の「▼」ボタンを押すと反転時の回転回数が半回転単位で減少するようなボタンを追加してもよい。
【0031】
さらに、制御装置11は、必要に応じて、回転部材8の反転時の回転回数と反転速度とを相対的に変化させる。反転時の回転回数が大きくなるにつれて、反転速度を速くすることで、反転時の時間短縮が可能であり、また、織機の主軸21との同期が可能となる。なお、一方向または他方向に回転した時の回転時間と、反転時の回転時間がほば同じになるのが望ましい。もちろん、回転部材8は、プロペラ型式のものとして構成することができる。
【0032】
【発明の効果】
本発明によれば、少なくとも2本の耳糸が通過する一対の案内部を有した回転部材を一方向に回転させ、続いて他方向に回転させることにより耳形成を行う電動耳組装置において、回転部材が一方向から他方向に反転する際に、その反転動作によって、耳糸が互いに絡まり、耳部分で隣り合う緯糸の間に緯糸が挿入されていないねじれが形成されるため、緯糸に絡んでいる互いの耳糸を締める効果が向上し、これよって緯糸の緩みを防止することができ、織物の品質向上に大きく頁献することができる。
【0033】
回転部材の反転時の回転回数を任意に設定可能とすることにより、耳糸のねじれの絡み具合が調整でき、また糸種、織機の主軸回転数などの少なくとも1つの条件ごとに、複数の回転回数を任意に設定可能とすれば、条件に対応する的確なねじれが形成できる。
【0034】
回転部材の反転時の回転回数と反転速度とを相対的に変化させると、反転時の回転回数が大きくなるにつれて反転速度が速くなるため、反転時の時間短縮が可能であり、また織機の主軸との同期が可能となる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for controlling an electric ear assembly device of a loom.
[0002]
[Prior art]
Japanese Patent No. 2933889 discloses a twist ear forming method using a twist ear forming apparatus. As shown in FIG. 1, the twist ear forming method includes a twist disk (rotating member) 4 having two eye holes (guide portions) 5 and 6 for guiding two twist yarns (ear yarns) 2 and 3. In the twist ear forming apparatus 1 provided, the twist disk 4 is rotated in one direction, and then the twist disk 4 is rotated in the opposite direction, thereby twisting or tangling the twist yarns 2 and 3 caused by the rotation in one direction. Are offset by rotation in the opposite direction. In this way, the weft 7 is held between the twists of the two twisting threads (ear threads) 2, 3.
[0003]
The technique disclosed in Japanese Patent Application Laid-Open No. 11-501999 discloses a device for forming a Reno ear in which a rotor (rotating member) is provided with an arm through which two twine threads are passed. After the rotation, the rotation direction of the rotor is reversed, and by rotating the rotor in the opposite rotation direction, twisting of the twine can be eliminated.
[0004]
[Problems to be solved by the invention]
According to the above-mentioned conventional technology, between the weft of the ear part inserted just before the reversal of the rotating member such as the twist disk or the rotor and the weft of the adjacent ear part, there is no twist due to the ear thread, They were crossing. For this reason, there is a disadvantage that looseness of the weft at the ear portion is apt to occur, which adversely affects the quality of the woven fabric.
[0005]
FIG. 2 shows, as an example, the situation of the above-mentioned drawback when the ear is formed in the direction opposite to the 100th pick by the ear forming method disclosed in the above-mentioned Japanese Patent No. 2933889, and is turned one turn to the right.
[0006]
In (1) of FIG. 2, the twist disc 4 is turned half a clockwise in a state in which the twist disc 4 has completed the half turn to the left (100th pick). In FIG. 2B, the twist disk 4 is further rotated rightward by a half turn. The rotations of (1) and (2) in FIG. 2 are performed continuously. In (3) of FIG. 2, the next weft yarn 7 flies toward the opening of the twist yarns 2 and 3.
[0007]
In (4) of FIG. 2, after the weft thread 7 has passed through the openings of the twist threads 2 and 3, the twist disc 4 is rotated half a clockwise direction. From here, the twist disk 4 is always rotated clockwise. After (5) in FIG. 2, (3) and (4) are repeated. In (5) of FIG. 2, before and after 100 picks (inside the circle), the twist yarns 2 and 3 are not entangled with each other, and the weft yarn 7 is easily loosened, which adversely affects the quality of the woven fabric. .
[0008]
Therefore, an object of the present invention is to make it possible to prevent the weft of the ear portion from being loosened when the ear is formed by using this type of ear assembly device.
[0009]
[Means for Solving the Problems]
With the above object, the present invention provides an electric ear assembly device in which, by inverting a rotating member that guides an ear thread, a twist in which no weft is inserted between adjacent wefts of an ear part is provided. Prevents weft loosening.
[0010]
More specifically, the control method of the electric ear assembly device according to claim 1 rotates a rotating member having a pair of guide portions through which at least two ear threads pass, in one direction, and then in the other direction. In an electric ear assembling apparatus that forms ears by rotating, when a rotating member is reversed from one direction to another, a twist in which a weft is not inserted is formed by the reversing operation.
[0011]
According to the second aspect, the number of rotations at the time of reversal of the rotating member can be arbitrarily set, and the number of rotations at the time of reversal of the rotating member and the reversing speed are relatively changed.
[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 3 shows an electric ear assembly device 10 for implementing the control method of the present invention. The electric ear assembly device 10 includes a rotating member 8, a driving device 9, and a control device 11.
[0013]
The rotating member 8 has guide portions 14 and 15 with two eye holes for guiding the two ear threads 12 and 13. The two ear yarns 12 and 13 are pulled out from the bobbins 16 and 17, respectively, pass through the guides 18, pass through the guide portions 14 and 15 of the rotating member 8, are entangled with each other, and hold the end of the weft yarn 7.
[0014]
The rotating member 8 is driven from the outer peripheral side of the rotating member 8 by a rotation transmitting means 19 such as a roller or a belt of a driving device 9 so as not to hinder the twisting movement of the two ear threads 12 and 13. The drive device 9 includes a drive motor 20 that can change the rotation direction, the number of rotations, and the rotation speed, and is controlled by the control device 11. The control device 11 rotates the drive motor 20 in the drive device 9 in synchronization with the main shaft 21 of the loom based on the setting data from the input device 22 based on the control method of the electric ear assembly device of the present invention. Control the direction, number of rotations and rotation speed.
[0015]
The control device 11 holds the weft by rotating the rotating member 8 in one direction by a predetermined number of rotations in a plurality of picks, temporarily reverses the rotation, and then rotates the rotating member 8 by a predetermined number of rotations in the other direction in a plurality of picks. Is performed repeatedly. In detail, according to the control method of the electric ear assembling device of the present invention, the driving motor 20 in the driving device 9 is driven, and the rotating member 8 is rotated in one direction a predetermined number of times by each pick to grip the weft. In the process of forming the ears, by repeatedly turning the rotating member 8 in the other direction for a predetermined number of rotations and holding the weft by repeating the rotation once and then for each predetermined number of picks, the rotation direction is reversed. In doing so, a twist in which the weft 7 is not inserted is formed by the reversing operation.
[0016]
Next, FIG. 4 shows a table of an ear formation process by the control method of the electric ear assembly device of the present invention, and a correspondence relationship between the number of picks and the number of rotations in the ear formation process. In FIG. 4, the ear formation is controlled by setting the number of rotations of the rotating member 8 at the time of reversal to one rotation, and immediately after the weft 7 at the 100th pick passes through the openings of the ear yarns 12 and 13, Of the rotation direction of. In the table of FIG. 4, the rotation direction of the rotating member 8 is assumed to be reversed in units of 100 picks, the left direction of rotation of the rotating member 8 is +, and the right direction is-. In this example, the rotation speed (the number of rotations) of the rotating member 8 is constant (fixed) during the fiber production.
[0017]
In the table of FIG. 4, in the period of 1 to 99 picks, the rotating member 8 rotates half a turn in the left direction (+) for each pick, so that the two ear threads 12 and 13 form a twist. , The end of the weft 7 is held. After the weft 7 crosses the ear yarns 12 and 13 at the 100th pick, the rotating member 8 rotates one turn to the right (-), so that the two ears are located between the 100th pick and the 101st pick. The yarns 12 and 13 form, as in a circle, a -1 turn twist in which the weft 7 is not inserted. Thereby, the loosening of the weft 7 at the 100th pick can be prevented.
[0018]
Thereafter, during the period of 101 to 199 picks, the rotating member 8 rotates half a clockwise (-) between picks, so that the two ear yarns 12 and 13 are twisted while forming the weft 7 Hold the end of After the weft 7 crosses the ear yarns 12 and 13 at the 200th pick, the rotating member 8 rotates one turn to the left (+), so that the two ears are located between the 200th pick and the 201st pick. The yarns 12 and 13 form a +1 turn twist with no weft 7 inserted. Thereby, the loosening of the weft at the 200th pick can be prevented. As described above, the rotation direction of the rotating member 8 is reversed in units of 100 picks, and forms a single twist.
[0019]
FIG. 5 is a table showing the ear forming process according to the control method of the electric ear assembling device of the present invention, and the correspondence between the number of picks and the number of rotations in the ear forming process. In FIG. 5, the ear formation is controlled by setting the number of rotations of the rotating member 8 at the time of reversal to one and a half rotations, the weft 7 passing through the openings of the ear yarns 12 and 13 at the 100th pick, and After the rotation is completed, the reversal is performed. Also in the table of FIG. 5, the rotation direction of the rotating member 8 is assumed to be reversed in units of 100 picks, and the left direction of rotation is + and the right direction is-. In this example, the rotation speed (the number of rotations) is constant (fixed) during the fiber production.
[0020]
In the table of FIG. 5, during the period of 1 to 99 picks, the rotating member 8 rotates a half turn in the left direction (+) for each pick, so that the two ear threads 12 and 13 form a twist. , The end of the weft 7 is held. After the weft 7 crosses the ear yarns 12 and 13 at the 100th pick, the rotating member 8 rotates half a turn in the left direction (+), and then rotates one and a half turn in the right direction (-). Between the pick 101 and the 101st pick, the two ear yarns 12 and 13 form a twist of (−1 rotation half + half rotation) = − 1 rotation in which the weft 7 is not inserted. Thereby, the loosening of the weft 7 at the 100th pick can be prevented.
[0021]
Thereafter, during the period of 101 to 199 picks, the rotating member 8 rotates half a clockwise (-) between picks, so that the two ear yarns 12 and 13 are twisted while forming the weft 7 Hold the end of After the weft 7 crosses the ear yarns 12 and 13 at the 200th pick, the rotating member 8 rotates half a turn in the left direction (-), and then rotates one and a half turn in the left direction (+). Between the and the 201st pick, the two ear yarns 12 and 13 form a + 1-turn twist in which the weft 7 is not inserted. Thereby, the loosening of the weft 7 at the 200th pick can be prevented. In this manner, the rotation direction of the rotating member 8 is reversed at a cycle of 100 picks, and forms a single twist.
[0022]
In this case, the twist in which the weft 7 is not inserted is formed by once passing through a spouting state (a state without twisting) in the reversing process, and further performing at least one rotation to make the opening state.
[0023]
As described above, according to the examples of FIGS. 4 and 5, by forming a twist in which the weft 7 is not inserted by the reversing operation of the rotating member 8, the ear yarns 12 and 13 are entangled with each other, and are adjacent to each other at the ear portion. A twist in which the weft 7 is not inserted between the matching wefts 7 is formed. For this reason, the effect of tightening the ear yarns 12 and 13 entangled with the weft 7 is improved. Therefore, it is possible to prevent the weft 7 from being loosened and to greatly contribute to improving the quality of the woven fabric.
[0024]
Further, according to the example of FIG. 4, since the twist can be formed with a smaller number of rotations by half a turn than the example of FIG. 5, the efficiency for weaving such as shortening of the time when the rotating member 8 rotates can be improved.
[0025]
FIG. 6 shows an example in which the number of rotations of the rotating member 8 at the time of reversal can be arbitrarily set using the control device 11 having a storage function. The control device 11 can store the correspondence between the number of rotations of the main shaft 21 of the loom (the rotation speed of the loom) and the number of rotations of the rotating member 8 at the time of reversing, by the storage function of the internal memory.
[0026]
Therefore, the operator operates the input device 22 and, for example, when the number of rotations of the main shaft 21 is 800 rpm, the number of rotations at the time of inversion = 1 and a half, and when the number of rotations of the main shaft 21 is 1000 rpm, the number of rotations at the time of the The number of rotations is set to one rotation.
[0027]
With this setting, when the number of rotations of the main shaft 21 of the loom is changed from 800 rpm to 1000 rpm during weaving, the number of rotations of the rotating member 8 at the time of inversion is changed from one and a half rotations to one rotation. As a result, when the spindle rotation speed is 800 rpm, the torsion is formed twice as seen in the circle in order to strengthen the tightness.
[0028]
There are the following two types of control of the number of rotations when the rotating member 8 is inverted. (1) The number of rotations at the time of inversion is set arbitrarily, and is fixed to the number of rotations during weaving. This is the example of FIGS. 4 and 5 described above. (2) A plurality of rotations are arbitrarily set for at least one condition such as the yarn type and the rotation speed of the main shaft 21 of the loom, and the yarn type and the rotation speed of the main shaft 21 of the loom are changed during weaving. In each case, the number of rotations is changed at any time to the number of rotations corresponding to the condition. This is the example of FIG. 6 described above.
[0029]
As described above, the number of rotations of the rotating member 8 at the time of reversing can be set arbitrarily, whereby the degree of entanglement of the torsion of the ear thread can be adjusted, and the thread type, the number of rotations of the main shaft 21 of the loom, and the like can be adjusted. If it is possible to arbitrarily set a plurality of rotation times for at least one of the conditions, an accurate twist corresponding to the conditions can be formed.
[0030]
The number of rotations of the rotating member 8 at the time of inversion may be set to an integral multiple of half a rotation, and may be set to n × half a rotation. Of course, the minimum number of rotations at which the twist can be formed between the two ear threads 12 and 13 is set to a settable minimum value. The settable minimum value is one rotation (half rotation + half rotation) in the control of FIG. 4, and one rotation and half (1 rotation + half rotation) in the control of FIG. Normally, since the rotating member 8 of the electric ear assembly device 10 rotates in units of half rotation, if the setting can be performed in units of half rotation, the setting itself is simplified. For example, for setting the number of rotations at the time of inversion, the input device 22 is provided with “▲” and “▼” buttons, and when one of the “▲” buttons is pressed, the number of rotations at the time of inversion increases by a half rotation, and the other “ A button may be added such that when the "▼" button is pressed, the number of rotations at the time of inversion is reduced by a half rotation unit.
[0031]
Further, the control device 11 relatively changes the number of rotations and the reversing speed of the rotating member 8 at the time of reversing, as necessary. By increasing the reversal speed as the number of rotations during reversal increases, the time during reversal can be reduced, and synchronization with the main shaft 21 of the loom becomes possible. It is preferable that the rotation time when rotating in one direction or the other direction is almost the same as the rotation time when reversing. Of course, the rotating member 8 can be configured as a propeller type.
[0032]
【The invention's effect】
According to the present invention, there is provided an electric ear assembly device for forming an ear by rotating a rotating member having a pair of guide portions through which at least two ear yarns pass in one direction, and then rotating the rotating member in the other direction. When the rotating member is reversed from one direction to the other direction, the reversing operation causes the ear yarn to be entangled with each other, and a twist in which no weft is inserted between the adjacent wefts at the ear portion is formed. This improves the effect of tightening each other's ear thread, thereby preventing the loosening of the weft thread and greatly contributing to the improvement of the quality of the woven fabric.
[0033]
By making it possible to arbitrarily set the number of rotations at the time of reversal of the rotating member, the degree of entanglement of the twist of the ear thread can be adjusted, and a plurality of rotations can be made for at least one condition such as a thread type and a main shaft rotation number of a loom. If the number of times can be set arbitrarily, an accurate twist corresponding to the condition can be formed.
[0034]
If the number of rotations and the reversing speed at the time of reversal of the rotating member are relatively changed, the reversing speed increases as the number of rotations at the time of reversal increases, so that the time at the time of reversing can be reduced, and the main shaft of the loom can be reduced. Can be synchronized.
