【産業上の利用分野】本発明は、緯入れ不良が発生して不良緯糸を自動で修 復し、再始動させる装置に関し、特に織段を防止するための装置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for automatically repairing and restarting a defective weft yarn when a weft insertion defect occurs, and more particularly to a device for preventing weft.

【0002】[0002]

【従来の技術】緯入れ不良が発生してこれを修復する装置としては、特開平 4−257348号に記載されているものが知られている。これは、反緯入れ側 に設けた緯糸センサが緯入れ不良を検知すると、停止信号が出力され、織機が更 に回転して筬打ちを行った後、次の緯入れサイクルで織機を停止する。これは、 織機が高速で回転していることから、急激に停止すると、筬や開口装置に負担が かかり、耐久性が低下するからである。織機停止後に、織機の主軸を逆転させて 開口装置を開閉口動作させ、これにより不良緯糸を織り前に露出させ、その後緯 糸除去装置を作動させて不良緯糸を除去して再始動するようにしている。2. Description of the Related Art As a device for remedying a weft insertion defect, a device described in Japanese Patent Laid-Open No. 4-257348 is known. This is because when a weft sensor provided on the reverse weft insertion side detects a weft insertion failure, a stop signal is output, the loom further rotates and performs beating, and then the loom is stopped in the next weft insertion cycle. . This is because the loom is rotating at a high speed, and if it suddenly stops, the reed and shedding device will be overloaded and durability will be reduced. After stopping the loom, the main shaft of the loom is reversed to open and close the shedding device to expose the defective weft yarns before weaving, and then the weft removing device is operated to remove the defective weft yarns and restart. ing.

【考案が解決しようとする課題】緯入れ不良糸を除去する際に、織機主軸を 逆転させて不良緯糸を織り前に露出させる必要があるが、この逆転動作時に筬が 筬打ち運動することになる。すると、織り前位置にある緯糸が布側へ押しやられ 、織前部の布の緯糸どうしの間隔が微小量異なり、織り前部の布の風合いが異な ってしまう、いわゆる織り段が発生する恐れがある。また、不良緯糸は開口状態 で除去されるのであるが、除去した後に織機を始動する際には、一旦筬打ちを行 った後に次の緯入れサイクルで緯入れされて始動するので、これによっても緯入 れされないまま筬打ちを行うようにしているので、前記と同様に織り段が発生す る恐れがある。本案はこのような問題を解決するため、不良緯糸を除去して再始 動する際に、不要に筬打ち動作をさせないことで、織り段を防止することを目的 とする。[Problems to be Solved by the Invention] When removing defective weft insertion yarns, it is necessary to reverse the weaving machine spindle to expose the defective weft yarns before weaving. However, during this reverse movement, the reeds make a beating motion. Become. Then, the weft thread at the cloth fell position is pushed toward the cloth side, and the distance between the weft threads of the cloth cloth at the cloth cloth part is slightly different, resulting in a different texture of cloth at the cloth cloth part. There is. In addition, defective wefts are removed in the open state.When the loom is started after removing it, it is beaten once and then wefted and started in the next weft insertion cycle. Also, since the reed is performed without being wefted, there is a possibility that a weaving step may be generated as in the above case. In order to solve such a problem, the purpose of the present invention is to prevent weaving steps by removing unnecessary defective weft yarns and restarting the weft yarns.

【0004】[0004]

【課題を解決するための手段】このため、本案は第1に緯入れ不良が発生し て織機を停止した後、不良緯糸を織り前に露出させ、不良緯糸を除去した後再始 動するようにした織機の緯糸修復装置において、前記織機停止後に織機の開口装 置と主軸の連結部を断つ断接手段と、該手段の断動作後に開口駆動装置装置を駆 動させて開閉口運動を行わせる手段と、該手段の作動後に不良緯糸を露出させる 手段と、該露出された不良緯糸を除去させる手段と、該除去手段にて緯糸が除去 された後、前記断接手段により断たれた連結部を接合させて再始動させる手段を 設けた。そして第2に、前記連結部を接合した後、再始動する以前に、緯糸を経 糸開口列内に挿入させる手段を設けた。[Means for Solving the Problems] Therefore, in the first aspect of the present invention, after the weft insertion failure occurs and the loom is stopped, the defective weft yarn is exposed before weaving, and the defective weft yarn is removed and restarted. In the weft restoration device of the loom, after the loom is stopped, the connecting / disconnecting means for disconnecting the connecting portion between the opening device of the loom and the main shaft, and the opening drive device device is driven after the cutting operation of the device to perform opening / closing movement. Means, a means for exposing the defective weft after the operation of the means, a means for removing the exposed defective weft, and a connection broken by the connecting / disconnecting means after the weft is removed by the removing means. A means for joining the parts and restarting was provided. Secondly, a means for inserting the weft yarns into the warp shed row is provided after joining the connecting portions and before restarting.

【作用】この構成にあっては、不良緯糸を織り前に露出させる際に、不要に 筬打ち動作を行わないので、織り段の発生が防止できる。また、不良緯糸を除去 した後、再始動する際に、緯糸を経糸列内に挿入した後、筬打ちするので、緯糸 が空のまま筬打ちれず、更に確実に織り段が防止できる。In this structure, when the defective weft yarn is exposed before the weaving, the beating operation is not unnecessarily performed, so that the occurrence of the weft can be prevented. Further, after the defective weft yarn is removed and when restarting, the weft yarn is inserted into the warp row and then beaten, so that the weft yarn cannot be beaten in an empty state, and the weft can be prevented more reliably.

【実施例】第1図を参照しつつ本発明を説明する。1は織機本体、2はヘル ドフレーム、3はヘルドフレームを駆動する開口駆動装置、4は開口駆動装置3 を駆動させる手段としてのモータ、5は織機本体の図示しない主軸と開口駆動装 置の連結部を断接させる手段としてのクラッチ、そして6は制御装置で、これら 織機本体1の図示しない緯入れ装置や、布巻取り・送り出し装置のモータ、更に は開口駆動装置3のモータ4、及びクラッチ5が接続され、これらの作動を制御 する。なお、織機本体1には緯入れ不良検知センサーや緯入れ不良糸除去装置が 設けてあるが、公知の装置でもあるので、説明を省略する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIG. 1 is a loom main body, 2 is a heald frame, 3 is a shedding drive device for driving the heald frame, 4 is a motor as means for driving the shedding drive device 3, 5 is a main shaft of the weaving machine main body and the shedding drive device (not shown). A clutch serving as a means for connecting and disconnecting the connecting portion, and 6 is a control device, which includes a weft inserting device (not shown) of the loom body 1, a motor of the cloth winding / feeding device, a motor 4 of the shedding drive device 3, and a clutch. 5 are connected and control their operation. Although the weaving machine main body 1 is provided with a weft insertion defect detection sensor and a weft insertion defect yarn removing device, the description thereof is omitted because it is a known device.

【0007】 次に図2のタイムチャートにしたがって作動を説明する。なお、横軸は織機主 軸角度、そして縦軸は下方に向かって時間の経過を示す。ここで、織機の主軸角 度300近辺で図外の緯入れ不良検知センサが緯糸無しを検知して制御装置6は 織機本体1を停止させる。その後、制御装置6はクラッチ5を断動作させる。な お、織機の停止原因が緯入れ不良以外、例えば経糸切れなどが発生した際には、 即座に修復して始動できないので、前記クラッチ5を作動させず、例えば特開昭 59ー36739に開示されているようなレベリング装置を作動させて、経糸を 揃え、経糸張力を均等にし、且つ緩和して織段を防止する。緯入れ不良で停止し た際には、クラッチ5を断動作させるが、これにより織機本体1の主軸と開口駆 動装置との連結が断たれる。次いで、制御装置6は特開平4ー257348に開 示されている不良緯糸除去装置を作動させ、不良緯糸を除去させる。このとき、 点線で示すような従来では、織機の主軸を逆転させ、一旦筬打動作させて経糸を 交差させて開口状態にし、その後不良緯糸を除去した後、主軸角度を位置合わせ して始動していたが、本案の実施例では逆転動作が行われない。これにより不要 な筬打動作による織段の発生が防止できるのである。その後、Dにて一本の緯糸 を経糸開口列内に挿入するよう、制御装置6から図外の緯入れ装置に指令を行い 、その後Eにて始動する。この始動前に一本の緯糸を経糸開口列内に挿入するこ とで、いわゆる空打ちをせずにそのまま製織動作が開始されるので、これによっ ても不良な筬打動作がおこなわれないことから、更に確実に織段が防止できるこ とになる。Next, the operation will be described with reference to the time chart of FIG. The horizontal axis shows the main shaft angle of the loom, and the vertical axis shows the passage of time downward. Here, when the weft insertion defect detection sensor (not shown) detects the absence of the weft yarn near the spindle angle 300 of the loom, the control device 6 stops the loom body 1. After that, the control device 6 disengages the clutch 5. However, if the cause of the loom stop is something other than weft insertion failure, such as warp breakage, the loom cannot be immediately repaired and started. Therefore, the clutch 5 is not actuated. By operating the leveling device as described above, the warp yarns are aligned, the warp yarn tensions are made uniform, and the warp yarns are relaxed to prevent the weft bar. When stopping due to weft insertion failure, the clutch 5 is disengaged, which disconnects the main shaft of the loom body 1 from the shedding drive device. Next, the control device 6 operates the defective weft removing device disclosed in JP-A-4-257348 to remove the defective weft. At this time, in the conventional case as shown by the dotted line, the main shaft of the loom is reversed, the beating operation is performed once to cross the warp yarns into the open state, then the defective weft yarns are removed, and then the main shaft angle is aligned and started. However, the reverse operation is not performed in the embodiment of the present invention. As a result, it is possible to prevent the occurrence of a weaving bar due to unnecessary beating operation. Then, at D, the control device 6 issues a command to the weft insertion device (not shown) to insert one weft yarn into the warp shed row, and then at E, the operation is started. By inserting a single weft thread into the warp shed row before this start, the weaving operation is started as it is without so-called blanking, so that no bad beating operation is performed. Therefore, the weft bar can be prevented more reliably.

【0009】 なお、始動に際しては、制御装置6より、織機本体1に設けた図外の布巻取り ・経糸送り出し装置のモータの回転制御を行って、織前位置や経糸張力を通常運 転時と同等になるように回転制御する。At the time of starting, the control device 6 controls the rotation of the motor of the cloth winding and warp yarn feeding device (not shown) provided in the loom body 1 to control the cloth fell position and the warp tension during normal operation. Rotation is controlled so that they are equal.

【考案の効果】本案は、第1に織機停止後、織機の開口装置と主軸の連結部 を断接手段により断ち、筬を停止した状態で開口駆動装置を駆動して開閉口運動 を行わせて経糸を交差させ、これにより不良緯糸を露出させ、該露出された不良 緯糸を除去するようにしたので、不要に筬打運動がなされないことから織段が防 止できる。また、第2にクラッチにて連結部を接合した後、再始動する以前に、 緯糸を経糸開口列内に挿入させるようにしたから、いわゆる空打動作しないこと から、更に確実に織段が防止できるという効果がある。EFFECTS OF THE INVENTION In the first aspect of the present invention, after the loom is stopped, the connecting portion between the shedding device of the weaving machine and the main shaft is cut by the connecting / disconnecting means, and the shed drive device is driven to perform the opening / closing movement while the reed is stopped. Since the warp yarns are crossed with each other to expose the defective weft yarns and remove the exposed defective weft yarns, the beating motion is not unnecessarily performed, and thus the weft can be prevented. Secondly, since the weft thread is inserted into the warp opening row after restarting after connecting the connecting portion with the clutch, the so-called idle operation does not occur, so that the weft is prevented more reliably. The effect is that you can do it.
