７３５１号公報に開示されているようなミス糸除去処理
装置に用いられるものである。(Prior Art) As shown in Japanese Patent Publication No. 39-29654, the yarn end catching device has a plurality of catching yarns arranged on the opposite weft entry side of the warp series (opposite the weft entry nozzle). is inserted into a twister placed on the side of the loom, and while being pulled toward the front of the loom (toward the woven fabric side), the caught yarn is inserted between the twister and the heddle at almost the same timing as the warp series. The weft insertion ends when the weft ejected from the weft insertion nozzle passes through the warp opening and the catching yarn opening, and then the catching yarn closes together with the warp. The yarn end of the inserted weft yarn is woven into the weft, and the yarn end is captured by twisting the weft yarn.
This is used in a mis-thread removal processing device such as that disclosed in Japanese Patent No. 7351.

動作の一部または全部を自動的におこなわせる。This error yarn removal processing device abnormally stops the loom when a weft insertion error occurs during weaving, and then reverses the rotation to approximately the maximum opening phase angle of the warp just before the error yarn was beaten, and removes the error yarn. The loom is exposed on the front of the weave, the exposed mis-thread is pulled out and removed by a traction device, and then the main shaft of the loom is adjusted to a predetermined phase angle and restarted. Some or all of these operations can be performed automatically. Let them do it.

引することでミス糸の引剥機能にすぐれている。Furthermore, the applicant has previously proposed the following error yarn removal processing device (Japanese Patent Application No. 60-141570). This device removes weaving from a fluid jet nozzle when the abnormal stop occurs due to a weft insertion error. The preceding weft yarns are stopped without being cut, and then the missed yarns are exposed on the fabric front, and more than 2 wefts worth of weft yarns are injected from the weft insertion nozzle. Therefore, this weft thread is turned over from the fabric front while being connected to the miss thread, forms a U-shape between the weft thread and the fluid jet nozzle, and is inserted into the opening between the warp thread and the catching thread. The top of this U-shape is then pulled by a mis-thread pulling/removal device disposed on the side opposite to the weft entry side of the caught yarn. Due to this traction, the misplaced yarns that have been driven into the woven fabric are sequentially pulled off from the above-mentioned reversal section and removed, and as a result, the inserted weft yarns are stretched straight between the weft insertion nozzle and the misplaced yarn traction device. . When this stretched weft is cut near the weft insertion nozzle, the inserted weft is pulled and removed together with the missed yarn. This device has an excellent ability to peel off misplaced threads by pulling them from the above-mentioned reversing section.
ところで、このような糸端捕捉装置とミス糸牽引除去装
置とをそなえる流体噴射式織機にあっては、緯糸検知器
の検知ミスなどにより緯入が正常におこなわれたにもか
かわらず織機が異常停止するという、いわゆる空止りが
発生すると、再始動後に捕捉糸が切断してしまうという
問題があった。By the way, in a fluid injection type loom equipped with such a yarn end catching device and a mis-thread traction removal device, the loom may malfunction even though weft insertion has been performed normally due to a detection error in the weft yarn detector. If a so-called idle stop occurs, there is a problem in that the catching thread will break after restarting.
それは、上記空止りが発生すると、前記ミス糸除去処理
装置が自動的に作動して当該緯糸（擬似ミス糸）の除去
処理をおこなうが、この際擬似ミス糸は正常に緯入され

撚回運動により当該緯糸がミス糸牽引除去装置から引出
されつつ捕捉糸に巻付いて塊状となり、この塊が撚回器
を通過し得ないままで捕捉糸が牽引されると、これが遂
には切断してしまうのである。This is because when the above-mentioned idle stop occurs, the above-mentioned error yarn removal processing device automatically operates to remove the relevant weft yarn (pseudo-error yarn), but at this time, the pseudo-error yarn has been inserted normally. The end of the thread is woven into the catching thread and is in a state where it is difficult to separate. Therefore, there may be a case where this pseudo-mistake yarn is connected to the mis-thread pulling and removing device while being tethered to the caught yarn. If the loom is restarted in this state, the twisting movement of the twister causes the weft yarn to be transferred to the mis-thread traction removing device. As it is being pulled out, it winds around the catching thread and forms a lump, and if the catching thread is pulled while the lump cannot pass through the twister, it will eventually break.
尚捕捉糸が切断するとその自動修復ができないので、作
業員が到来するまで織機を停台させなければならず、こ
れによって稼動効率が低下してしまう。If the captured thread is cut, it cannot be automatically repaired, so the loom must be stopped until a worker arrives, which reduces operating efficiency.
そこで本発明の課題は上述のような塊が形成されないよ
うにする点にある。Therefore, an object of the present invention is to prevent the formation of lumps as described above.
前記課題を解決した本発明の手段は、糸端捕捉装置から
ミス糸牽引除去装置へ至る糸道に臨ませて糸カッタを配
設したものである。The means of the present invention which solves the above problem is that a yarn cutter is disposed facing the yarn path leading from the yarn end catching device to the mis-thread pulling and removing device.
前記手段によれば、緯糸が前述したように糸端捕捉装置

た場合、当該糸道に配設した糸カッタがこれを切断する
ので、この緯糸はミス糸牽引除去装置からそれ以上引出
されることなく、したがって塊状に巻付くという事態が
回避される。According to the above-mentioned means, when the weft yarn is connected to the mistaken yarn traction removal device while being tethered to the yarn end catching device as described above, the yarn cutter disposed in the yarn path cuts it. The weft yarn is no longer pulled out of the erroneous yarn traction and removal device, so that winding in a lump is avoided.

It is assumed that the weft cutting timing by the cutter 45 is set to lθ''. Also, during the error thread removal process, the loom control device (not shown) controls the phase angle sensor 5 such as an encoder provided on the main shaft 1. Upon receiving the signal, as will be described later, a corresponding operation instruction is given at a corresponding time.

At the same time, the gripper 41 releases the weft W. As a result, the weft corresponding to one pick, which has been wound and stored on the drum 31 of the weft length measuring and storage device 30, is ejected from the weft insertion nozzle 2o, and passes through the opening between the warp Y and the catching yarn 51.

緯糸を切離す。Here, the gripper 41 grips and brakes the weft yarn, and at the same time or slightly prior to this, the discharge stroke of the weft insertion pump 17 ends, and weft insertion is completed. In this process, the reed 7 moves past the warp maximum opening phase of 180 degrees and moves forward, and on the way, the weft detector 48 comes into contact with the weft at the 330'' point and detects the presence of the weft.The reed 7 moves forward. Subsequently, the weft yarn is driven into the fabric front F at 0°, and immediately after that, at 10°, the cutting cutter 45 operates to separate the weft threads connected to the weft insertion nozzle 20.

It is being towed at high speed. As a result, tension is applied to the weft yarn, and after several picks of the beating, the yarn end cutter 47 is operated to cut off the captured yarn end from the weft matrix.

順次おこなわれる。If a weft insertion error occurs during the above operation, the above 330
', the weft detector 48 detects the absence of yarn, and in response to this detection signal, the weft detector 48 detects the absence of yarn, and upon receiving this detection signal, the cut prevention means 46
is operated for a predetermined period of time. This prevents the cutting movement of the cutter 4'5. Further, the cutoff valve 25 is closed to stop the weft insertion function, and the stop phase angle is set to 300° to instruct the main motor 2 to stop abnormally. As a result, reed 7 reeds the erroneous yarn related to the weft insertion error, and then reeds 1
It passes the phase position of 80' and stops at the next 300° [Figure 2 (A)]. Reference numeral M in the figure indicates a miss yarn, and by preventing the above-mentioned cut, the next operation is sequentially performed in accordance with instructions from the zero-thread control device connected from the fabric front F to the weft insertion nozzle 20.

先部に臨み、ここで切断される。After that, the phase position is reversed to 180'' and the pseudo-mistake thread M'
is exposed on the fabric front [Fig. 3 (B)), and after generating a suction airflow in the suction head 61, the weft stored on the drum 31 is inserted in a U-shape, and the folded part A from the fabric fabric is exposed. Pull it off by pulling it off [Figure 3 (C)]. Therefore, the insertion system extends between the weft insertion nozzle 20 and the suction head 61. If the pseudo-mistake yarn ``M'' is not peeled off from the captured yarn 51 during this process,
This is drawn into the rad 61 by suction while being tethered to the catching thread [FIG. 3(D)]. After that, the inserted weft is cut off [Fig. 3 (E)), the inserted weft is exposed to the fabric front and removed by suction [Fig. 3 (F)], and the position is adjusted to the restart position of 300° [Fig. 3 ( G)], restart preparation and restart [FIG. 3(H)] proceed with the pseudo-mistake yarn M' being tethered. After the restart, as the captured thread 51 is pulled forward as described above, the above-mentioned mooring section also moves forward, and the thread path is moved forward as shown by the two-dot chain line in FIG. 3(H). Wa faces the cutting edge of the razor-shaped thread cutter 7o and is cut there.

In this case, if the error thread traction removal device 60 is left in operation for a predetermined time after restarting, the tethered pseudo error thread will come into contact with the cutting edge while being applied with tension.
There is no need to worry about cutting mistakes. [In addition, a heat cutter can also be used as the above-mentioned contact cutting type thread cutter, and a chain type cutter can be used to carry out the pulling and peeling stage [Figure 2 (D) or Figure 3 (D)] It can also be configured to operate at a later time.
