糸を手掛りとしてミス糸の引き出し除去が行われる。A weft processing device for removing the above-mentioned miss yarn, which becomes a weaving mark of the woven cloth, from the woven cloth is disclosed in Japanese Patent Publication No. 56-27621 and JP-A No. 61-24533.
No. 9 and JP-A-62-21843.
In the processing means disclosed in Japanese Examined Patent Publication No. 56-27621, the miss yarn is separated from the outside of the warp opening by the jet fluid from the outside of the warp into the inside of the warp opening by the suction pipe which can enter from the side into the warp opening. The method of sucking and removing the miss yarn is adopted. In the processing means disclosed in Japanese Patent Laid-Open No. 61-245339, when the machine is stopped due to the occurrence of a weft insertion error, the following weft yarn is connected to the miss yarn while preventing the weft insertion, and is delivered to the winding device for pulling out the miss yarn. With this winding operation, the miss yarn is pulled out from the cloth fell to the side and removed.
In the processing means disclosed in Japanese Patent Laid-Open No. 62-21843, when the machine is stopped due to the occurrence of a weft insertion error, the following weft yarn is inserted into the weft yarn while being connected, and the miss yarn is removed by the jet fluid acting from outside the warp opening. The weft is separated from the weft into the warp shed, and the trailing weft is used as a clue to remove the miss yarn.

要な時間が大幅に増え、処理効率の低下を招く。(Problems to be solved by the invention) However, in the processing means disclosed in JP-A-61-245339, the miss yarn is directly pulled out and separated from the cloth fell sideways while receiving the gripping action of the upper and lower warp groups. The separation force from the cloth fell to the inside of the warp opening becomes smaller as the miss yarn separation proceeds to the weft insertion side, and the yarn tension due to the lateral pulling out increases and the yarn is easily cut. Therefore, there is a drawback that the drawing speed cannot be increased and the drawing processing time becomes long when the weaving width is wide. Although there is no risk of yarn breakage with the processing means disclosed in Japanese Patent Publication No. 56-27621 and Japanese Patent Laid-Open No. 62-21843, which separate the Musi yarn on the cloth by the fluid jetted from the cloth fell side to the inside of the warp opening, It is difficult for the miss yarn on the cloth fell which is being held by the warp group to slip through the warp group from outside the warp opening and to effectively act the jet fluid. Moreover, if the miss yarn is separated by the jetting fluid over the entire weaving width, the time required for separating the miss yarn is significantly increased, and the processing efficiency is reduced.

から除去される。(Operation) That is, when the weft following the weft insertion failure is connected to the defective weft, the weft insertion main nozzle retracts due to the reverse rotation of the machine, the jetting action of the jet fluid, or the mechanical action. The trailing weft is set in the jetting area of the auxiliary nozzle by the hook action or the like. Next, fluid injection in the auxiliary nozzle for weft insertion is performed sequentially or all simultaneously from the main nozzle side for weft insertion. As a result, the jet fluid in the weft-insertion auxiliary nozzle on the weft-insertion main nozzle acts on the succeeding weft, and the defective weft on the cloth fell is separated from the cloth fell side to the inside of the warp opening via the succeeding weft. Due to the jetting direction of the auxiliary nozzle for weft insertion, there is a separating action force from the cloth fell side to the inside of the warp opening, but this action force is connected to the defective weft yarn and the weft yarn on the main nozzle side is fixed for weft insertion. Since it is large, the defective weft yarn, which is large and is gripped by the upper and lower warp groups, is easily separated from the cloth fell to the inside of the warp opening. As the defective weft yarn is separated from the cloth fell, the defective weft yarn sequentially moves into the injection region of the downstream weft insertion auxiliary nozzle, and the separation action of the defective weft yarn becomes the ejection action of the downstream weft insertion auxiliary nozzle. It will be inherited. The defective weft yarn thus separated from the cloth fell into the warp shed is removed from the warp shed by the suction means.

織前上の不良緯糸が経糸開口内へ分離される。When the succeeding weft is not connected to the defective weft, the defective weft end on the side of the main weft inserting nozzle is arranged from the cloth fell to the injection region of the auxiliary weft inserting nozzle by the mechanical gripping action, and the same as above. The defective weft yarn on the cloth is separated into the warp shed by the jetting action of the auxiliary weft insertion nozzle.

配置保持される。Then, by opening the electromagnetic valve 23A, the weft-insertion main nozzle 2 communicates with the fine-injection circuit, and fine injection is performed from the weft-insertion main nozzle 2. At the same time as the electromagnetic solenoid
10 is excited and the weft thread locking body 10a is separated from the thread winding surface 4a. Fine injection of main nozzle 2 for weft insertion and weft lock body 10
When the locking action of a is released, the winding yarn on the yarn winding surface 4a is pulled out and ejected from the weft insertion main nozzle 2 into the warp yarn opening. When this unwinding of yarn is detected by the weft detector 11,
Immediately, the electromagnetic solenoid 10 is demagnetized to prevent the subsequent unwinding of the wound yarn. Therefore, the trailing weft Y1 corresponding to one winding is inserted in the warp opening, and the trailing weft Y1 inserted in the weft inserting main nozzle 2 is as shown in FIGS. 1 and 2 (a). Due to the slight jetting action, it is arranged and held in the jetting region of the weft inserting auxiliary nozzle 12A on the weft inserting main nozzle 2 side in a bent state.

滑かつ迅速に分離される。After demagnetizing the electromagnetic solenoid 10, the electromagnetic valves 13A, 13 are relay-opened and closed. First, the electromagnetic valve 13A on the weft-insertion main nozzle 2 side is opened to open the weft-insertion auxiliary nozzle 12A on the weft-insertion main nozzle 2 side. Fluid ejection is performed. As a result, the bent portion of the succeeding weft Y1 arranged and held in the jetting area of the weft-inserting auxiliary nozzle 12A receives the jetting action of the weft-inserting auxiliary nozzle 12A and is pulled in the weft-inserting direction. This pulling action acts on the miss yarn Y'on the cloth fell W1 as a separating force from the cloth fell W1 side to the inside of the warp opening, and the separating direction is the miss yarn Y which is subjected to the gripping action of the upper and lower warp groups T. This is a direction in which a small force is required to separate ′ from the cloth fell W1. The direction of the jetted air is as described above, and the miss yarn Y '
Since the weft yarn Y1 on the side of the main nozzle 2 which is continuous with the main nozzle 2 cannot be pulled out on the side of the same nozzle 2, even a small force acts on the miss yarn Y'as a strong separating force. Therefore, the miss yarn Y'part on the weft inserting main nozzle 2 side is smoothly and quickly separated into the inside of the warp yarn opening.

This weft insertion auxiliary nozzle is placed in the area
Receives 12 injections. As a result, the miss yarn Y'on the cloth fell W1 receives the separating action similar to the above, and is separated inside the warp shed. After that, the same separation is performed, and all the miss yarns Y'on the cloth fell W1 are smoothly and quickly separated into the inside of the warp shed without cutting, regardless of the width of the cloth.
