この発明は流体噴射式織機における給糸科の結び［１除
去方法、更に詳しくは給糸替の際の結び目を含む緯糸が
織布に織り込まれるのを防止するための方法に関する。Detailed Description of the Invention (Field of Industrial Application) This invention relates to a method for removing yarn feeding knots [1] in fluid jet looms, more specifically, a method for removing knots from yarn feeding in a fluid jet loom, and more specifically, a method for removing weft yarns containing knots during yarn feeding change. Concerning methods to prevent this from occurring.

続運転を行っている。(Prior art) In a fluid jet loom, the rope production speed is high, so several yarn feeders are prepared in advance on the yarn feeder stand, and the tail end of the yarn feeder is connected to the yarn end of the next yarn feeder. By tying them together, yarn feeding and beating are performed automatically, allowing continuous operation of the loom.

はこの結び［１の影響は［１：＆上火きなものでないの
で、この結び［Ｉの存在が致命的な織物欠陥となること
は多くはない。When such an operation method is adopted, a knot]-1 is woven into the woven fabric each time the yarn is fed. In general textiles, the effect of this knot [1 is not [1:&], so the presence of this knot [I does not often cause a fatal textile defect.

ければならないことは良く知られているところである。However, in the case of special fabrics such as glass cloth used as the base material for printing plates for mounting parts, localized I bulges in the weft cross section at the knots can cause prints (
It is well known that it is necessary to completely eliminate knots from being included in the weft threads and woven into the fabric, as this is directly linked to irregularities in the thickness of the insulating layer of the board.

転してやろうとするものである。From this point of view, methods such as Japanese Patent Publication No. 14137/1980, Japanese Patent Publication No. 50895/1982, and 50896/1988 have been proposed. In other words, when the remaining amount of the yarn feeder currently being inserted is low and the time to weave the knot approaches, the loom is stopped in the open state and the weft insertion nozzle is used to insert the weft by a predetermined amount. The idea is to remove the knots by blowing away the weft to the opposite side of the fabric, and then restart the loom.

び目を有する緯糸の排出が確実ではない。However, in such a conventional method, the Mars thread is blown away before and after the knot, which is undesirable because it wastes a lot of thread and fluid for blowing waves. Since the weft threads are blown between the opened warp threads, the weft threads and warp threads are easily damaged, and the knots may get caught in the middle, making it difficult to discharge the knotted weft threads.
更には１反緯入側に吹き流された糸の処理が確実性に欠
け、しかもこれを実施するための装置の構造が複雑とな
るといった欠点があった。Furthermore, there is a drawback that the treatment of the yarn blown away to the weft entry side is not reliable, and the structure of the device for carrying out this process is complicated.

After detecting that the yarn has been unwound from the yarn feeder, the loom is stopped until the knot opening advances to the position immediately before weft insertion, and then the knot removing device located between the main nozzle and the woven fabric The loom is operated to remove the knot, and then restart the loom at a predetermined timing.
（実施例） 以下、この発明の実施例について現用する。(Example) Hereinafter, embodiments of this invention will be used.
この発明の方法を実施するための装置としては、例えば
第１図に示すように、センサｌと制御回路１０とからな
る。An apparatus for implementing the method of the present invention includes, for example, a sensor 1 and a control circuit 10, as shown in FIG.
センサｌは例えば馬蹄形をしたフレーム１ａの先端部に
投光器１ｂと受光器１ｃを有する光電スイッチであって
、フレーム１ａの内奥部にある糸Ｘが光軸１ｄを横切っ
て繰り出されるとき受光′ｋｉｌ Ｃがそれを検知して
電気信号として出力する。The sensor 1 is, for example, a photoelectric switch having a light emitter 1b and a light receiver 1c at the tip of a horseshoe-shaped frame 1a, and receives light when the thread X located deep inside the frame 1a is unwound across the optical axis 1d. C detects it and outputs it as an electrical signal.

ドＬの給糸体３１ａのテールエンドと給糸体３１ｂの糸
端との結び目Ｘａの縁り出しタイミングを検出する如く
セットされている。即ち。As shown in FIG. 2, the sensor l is set to detect the timing of the edge of the knot Xa between the tail end of the yarn feeder 31a of the yarn feeder stand L (not shown) and the yarn end of the yarn feeder 31b. . That is.
給糸体３１ａはドラム式緯糸測長貯留装置３２及び緯入

Ｗとして給糸スタンドに仕掛けられており、この給糸体
３１ａの糸Ｘがすべて消費されると結び目Ｘａを介して
次の給糸体３１ｂの糸Ｘが連続的に緯糸Ｗとして繰り出
され、センサ１はこの結び目の通過を検出する。The yarn feeder 31a is installed in a yarn feeder stand so that the yarn X passes through a drum-type weft length measurement and storage device 32 and a weft insertion nozzle 33, and serves as a weft W for weaving a woven fabric C. When all of the yarn X is consumed, the yarn X of the next yarn supplying body 31b is continuously let out as a weft W through the knot Xa, and the sensor 1 detects the passage of this knot.
一方、緯入れノズル３３と織布Ｃの緯入れ側端部との間
には緯糸飛走路に対向して噴気ノズル４１と、カッタ４
２と吸引ノズル４３とを主要構成要素とする糸除去装置
が設けられている。On the other hand, between the weft insertion nozzle 33 and the weft insertion side end of the woven fabric C, there is a blow nozzle 41 and a cutter 4 facing the weft flight path.
2 and a suction nozzle 43 are provided as main components.

てアントゲ−）１３に入力している。Next, explaining the control circuit 1O, the output of the sensor 1 is connected to the set terminal of the flip-flop 12 via the amplifier 11, and the output is connected to the AND gate 13 together with the pick signal 21 from the pick sensor (not shown). has been done. Here, the pick sensor is, for example, a proximity sensor that detects the rotation of the main shaft of the loom, and generates one pulse signal corresponding to each pick operation of the 1F & loom. This pulse signal is then inputted to the computer gamer 13 as a big signal 21.

The output of the comparator 15 is connected as a command signal 22 via an amplifier 17 to a loom control device and a control circuit for a yarn removing device (not shown). Furthermore, a loom operating signal 23 is inputted to the control circuit 10 from the f17 control device of the loom (not shown), and is sent to the reset terminal of the flip-flop 12 and the counter 14 via an amplifier 18 and a one-shot mono multivibrator 19.
Clear terminal and connected to.

ク動作回数である。As a result, the thread X crosses the optical axis 1d of the sensor l, νJ,
The sensor l outputs a signal. Then, this signal passes through an amplifier 11 and sets a flip-flop 12, and the number of subsequent pick operations of the loom (weft insertion operation of the loom) is counted by a counter 14 via an AND gate 13. Since the flip-flop 12 and the counter 14 are reset and cleared by the 11&a operation signal 23, the number of pick operations counted by the counter 14 accurately corresponds to the pick operation of the loom after the end time T of the yarn supply body 31a. It is the number of times.

、糸除去装置が起動せしめられる。The content of the counter 14 is compared with the setting content of the setter 16 in the comparator 15, so after the sensor 1 operates and the pick operation is performed a predetermined number of times set by the setter 16, the comparator 15 A signal is output which is used as a command signal 22 via amplifier 17 to stop the #& machine and to start the thread removal device. That is, the yarn supply body 3
When the yarn X of 1a is completely consumed, the loom is stopped after a predetermined number of pick operations set by the setting device 16, and the yarn removing device is activated.

断されている。In this case, when the command signal 22 is issued, the loom starts to stop in response, but during the weft insertion period that occurs during this braking, the locking pin 32a is in the locked state. By keeping it on an island, weft insertion is prevented. Further, the weft yarn W is cut at the tip of the weft insertion nozzle 33 by the normal operation of the yarn feeding cutter 42.
そして織機完全停止後、織機逆転操作による、いわゆる
ピックファインディング動作を経て織機は経糸閉口状態
となって、この後の所定のタイミングで糸除去装置が起
動せしめられる。After the loom has completely stopped, the loom enters a warp-closed state through a so-called pick-finding operation by reversing the loom, and the thread removing device is then activated at a predetermined timing.

到達しており、後述の緯糸Ｗの排出礒を少なくできる。By the way, the number of picks set in the setting device 16 is 11.
It is sufficient to set the number of picks where X a is included in the weft W and woven into the woven fabric C, but it is most preferable to set the number to one bit less. Then, the knot Xa will be By the pick operation, the weft yarn has reached the position where it is woven into the woven fabric AiC, that is, the position immediately before being woven into the woven fabric C, and the amount of discharge of the weft yarn W, which will be described later, can be reduced.

れが行われる。In this way, Il&n is stopped at an angle where the warp shedding is almost closed, and the yarn removal device is activated. During the operation with this yarn removal bag, the weft length measuring and storage device 32 is engaged (F pin 3
2a to release the weft yarn lock +L at the drum H. Then, the operation of the yarn removing device, i.e., the jet nozzle 4
1 and the suction nozzle 43 to pull out the weft W protruding from the tip of the Korean insertion nozzle 33, and forcibly remove the next big weft W including the knot rl X a stored in the weft length measurement storage device 32. to be discharged. and,
At a predetermined timing after this discharge, the weft locking pin 32a is activated to the weft locking state yE', preliminary winding is performed by the rotating yarn guide YG, and the loom is automatically operated at a predetermined timing thereafter. I will restart it. With this restart, the weft yarn W being drawn into the suction nozzle 43 from the weft insertion nozzle 33 is guided to the operating range of the yarn feeding cutter 42 by the action of the guide 47 during the beating process. After beating, the weft yarn W continuing from the weft insertion nozzle 33 to the suction nozzle 43 is cut by the yarn supply cutter 42, and the next weft insertion is performed.

はいうまでもない。Furthermore, in the apparatus used to carry out the above-mentioned present invention,
At the time of knot removal, the weft W on the weft length measuring and storage device 32 is brought into the unlocked state by the locking pin 32a, and the locking pin is brought into the locked state after a predetermined period of time has elapsed. An unwinding sensor is provided to detect the unwinding of each winding from the weft length measuring storage device 32, and the unwinding signal from this unwinding sensor is counted, and when a predetermined number of windings have been unwound, the locking pin is activated. It goes without saying that 32a may be kept in a locked state.
上記実施例では、一般に経糸開口が開いた状態で織機を

経糸を傷付けることもない。(Effects of the Invention) According to the method of the present invention, knots are captured and removed between the cotton insertion nozzle and the end of the woven fabric, so the knots do not enter the warp opening, so unlike the conventional method, knots are removed when the knots are removed. It does not damage the warp threads.
また結び目除去に当たってエアの吹き流しによって緯糸
を吹き流さないので、緯糸及び流体の無駄な消費がなく
省資源の見地及び織布のコストの点から非常に右利であ
る。Furthermore, since the weft yarns are not blown away by the air stream when removing knots, there is no wasted consumption of the weft yarns and fluid, which is very advantageous from the standpoint of resource saving and the cost of the woven fabric.
