現象は緯入れ時の緯糸張力が大きいレピア織機において
顕著である。However, in the case of this prior art, there is a disadvantage that the defective weft easily jumps up during the work of removing the defective weft and is easily entangled with the warp and peripheral members. That is, the defective weft yarn is beaten in front of the weaving fabric with the tension being held internally. Therefore, when the defective weft is pulled out and a part of the defective weft is pulled away from the cloth cloth, particularly in the case of a strongly twisted yarn, the defective weft shrinks by jumping to the yarn supplying side by the action of the tension contained in itself. Sometimes. At this time, the defective weft itself contracted may be entangled at the end of the yarn on the yarn feeding side or entangled with the warp or the yarn guide, which may make it difficult or impossible to remove the defective weft after the operation. Such a phenomenon is remarkable in the rapier loom where the weft tension during weft insertion is large.

The support member 1 has a tip curved slightly upward to support the woven fabric F from below in the vicinity of the cloth fell. A bracket 3 is engaged with two grooves 1a in the weft direction formed on the front surface of the support member 1 by bolts 4 and nuts 6, and the bracket 3 has a rotary output shaft in the weft direction. The actuator 5 is assembled. Further, a rod-like splashing prevention member 9 extending in the warp direction is attached to the output shaft of the rotary actuator 5 via a holder 7. Therefore, by loosening the nut 6, the rotary actuator 5 can move in the weaving width direction together with the bracket 3, and accordingly, the blocking member 9 can freely select its installation position in the weaving width direction. As this position, for example, the inner side is selected from the non-feeding side by 1/3 of the weaving width.

At this time, the movement guide member 22 forming one component of the defective weft separating mechanism is in the position shown in FIG. For example, weft Y
When 4 is wefted, the corresponding selection finger F4 descends to the selected position, and the weft Y4 is captured between the fixed guide member 21 and the selection finger F4 by a rapier (not shown) that moves toward the warp shed. . As the rapier advances, the weft Y4 captured by the rapier is bent by the yarn guide 32 in the lowered position, guided between the fixed blade 33a and the movable blade 33b of the weft cutter 33, and then cut. As shown in FIG. 8, the weft Y4 put in the weft is guided by the lower side of the fixed guide member 21 in accordance with the beating, and joins with the other wefts Y1, Y2, Y3. In this way, a predetermined weft yarn is selected and weft-inserted by the rapier. When a weft insertion failure occurs during weaving, a weft corresponding to a defective weft among the weft feelers provided for each weft between a known weft feeler, that is, the selection fingers F1 to F4 and a weft storage device (not shown). The feeler outputs a weft insertion failure signal. In conjunction with the output of the weft insertion failure signal,
A loom stop signal is output. At this time, the selected finger stops operating and remains stationary in the non-selected position.
Before the defective weft is beaten by receiving the weft insertion failure signal, the movement guide member 22 constituting the separating mechanism of the defective weft removing device is moved to the separating position shown in FIG. 9 by the driving mechanism (not shown). Along with the beating, the defective weft slides on the lower side of the fixed guide member 21 and is guided to the recess formed by the moving guide member 22 and the fixed guide member 21. This separates the defective weft from the other wefts.

As shown in (4), the fixed guide member 21 is moved into another concave portion formed in the fixed guide member 21. In this state, an unillustrated shedding device is reversed to eject the defective weft. At the same time, the selection finger corresponding to the defective weft is forcibly driven to the selection position as shown in FIG.

Further, the hook 31 catches the defective weft thread upward in a mountain shape. This state is shown in FIG.

4に示す。Thereafter, the defective weft is wound by the lever 41a of the winding drum 41 of the winding mechanism of the defective weft removing device to lock the defective weft. Since the defective weft thread is passed through the concave portion of the fixed guide member 21 which is separated from the cloth fell, it is separated from the cloth fell 13 with the winding. This state is shown in FIG.

す。During weaving, the weft yarn is pulled while being pulled by the rapier, so that the defective weft yarn is also beaten with the built-in tension as described above. Therefore, particularly when the weft yarn is a strong twist yarn, when the weft yarn is pulled apart to some extent from the cloth fell, the defective weft yarn jumps toward the shrinking direction, that is, toward the yarn supplying side due to the tension contained therein. However, by contacting the blocking member 9 already in the working position, the blocking weft is once blocked by the blocking member 9 during the bouncing motion of the defective weft. Immediately after this state is shown in FIG. 5, the energy loss due to this collision causes the tension of the entire defective weft to decrease, resulting in a loose state. This state is shown in FIG.

の除去に対して重大な影響はないのである。In this slack state, the defective weft is regularly taken out of the shed by the defective weft removing device.
At this time, there occurs a phenomenon that defective wefts gather on the blocking member 9, but the weft insertion side is farther from the blocking member 9 (left side in the figure).
Since the length of the defective weft is very short, it does not have a significant effect on the removal of the defective weft after that.

る必要があるということである。The range of "near the cloth fell" in the present invention is considered as follows. The blocking member needs to be close to the cloth fell so as to come into contact with the defective weft that jumps in the shrinking direction. However, if the blocking member is strongly brought into contact with the cloth fell, there is a risk that resistance may occur when removing the defective weft thread or that a weave defect may occur. Therefore, it is necessary to position the blocking member close to the cloth fell to such an extent that such inconvenience does not occur.

限定されない。The range of the "predetermined position in the weft width direction" in the present invention is considered as follows. This basically indicates the range in which the defective weft yarn exists in the weft width direction. If the position of the blocking member is too close to the tip of the defective weft in the weft width direction, the defective weft may slip through the blocking member when the defective weft is contracted by the built-in tension. On the other hand, if the weft yarn is too close to the yarn supplying side, the defective weft yarn that jumps and jumps increases in length, which may cause the warp yarn and the guide member to be entangled. Therefore, it is preferable that both conditions are satisfied, and specifically, the position inside 1/3 to 1/2 of the weaving width from the anti-feeding side is preferable. Also,
The defective yarn removing device is not limited to that of the embodiment, and may be, for example, the defective yarn removing device of the fluid jet loom mechanism disclosed in JP-A-61-245339. Further, the present invention is not limited to the device provided on the yarn supplying side, and for example, may be applied to a defective yarn removing device provided on the opposite yarn supplying side and removing so-called cut yarn which is cut midway during weft insertion. .
At this time, the blocking member is provided at the "predetermined position in the weaving width direction" so as to satisfy the above condition for the bobbin cut yarn on the non-feeding side. That is, the defective yarn removing device that is a target in the present invention is not limited in its configuration as long as it is a device that is provided on the weave end side and pulls the defective yarn while separating it from the cloth fell.

のような現象の発生を防止できる。Although the rod-shaped blocking member is used in the above example,
Instead of this, a plate-shaped blocking member that is thin in the weft width direction may be used. In the case of a rod-shaped blocking member, a phenomenon in which a defective weft that has jumped over is bent into a U shape over the blocking member (Fig. 5)
(Indicated by the one-dot chain line), and becomes a resistance when removing defective wefts. If the blocking member is formed in a plate shape as shown in FIG. 11, the occurrence of such a phenomenon can be prevented.

Since the range of existence of defective wefts usually varies, if a single blocking member cannot find an arrangement position that satisfies the above-mentioned "predetermined position in the weaving width direction", a plurality of blocking members must be provided. It is desirable to provide it along the weft width direction. Further, the drive mechanism may be one that linearly reciprocates the blocking member. The blocking member and the drive mechanism may be provided above the woven cloth.

不都合も起こらない。According to the present invention, as a result of providing the blocking member, the defective weft collides with the blocking member in the course of jumping and the splashing energy is absorbed and does not bounce back to the yarn supplying side. Therefore, the defective weft yarn itself is not entangled with itself, and the warp yarn and the peripheral members are hardly entangled. As a result, there is no inconvenience that it becomes difficult or impossible to remove the defective weft thread after that.
