る。The photoelectric weft detection feeler is a control means for monitoring the weft insertion state during operation of the loom by utilizing the photoelectric effect of the light receiving element, and stopping the loom when an abnormality is detected. And the reflected light receiving type
It has been put to practical use. By the way, the reflected light receiving type is
There is an advantage that the illumination light source and the light receiving element are integrated into a single unit so that the installation space can be reduced and the aiming of the photoelectric can be set relatively easily. When such a type of weft detection feeler is used, the light receiving element is illuminated by illuminating the weft flight path on which the weft should fly and changing the amount of reflected light that changes depending on the presence or absence of the weft on the flight path under illumination. To obtain a detection signal.
It has a thickness of about 0.1 mm to 1.0 mm, is an extremely thin piece, and is attached to a sley that performs rocking motion of the reed wing, so that the reed always vibrates. Due to this vibration, the amount of light reflected from the photoelectric weft detection feeler and reflected by the reed wing changes. Here, it is difficult to electrically distinguish and detect the change in the amount of light reflected from the weft and the change in the amount of reflected light caused by the reed wing vibration. To be detected.
Therefore, even when there is no weft due to a weft insertion error, a so-called overlook phenomenon occurs in which the change in the light amount due to the reed wing vibration indicates that the weft is present.
さらに、前記した筬羽が薄いことによる振動の増幅が
大きいため、織機回転数が高いことと、相乗してその見
逃し傾向が多くなる。Further, since the vibration is greatly amplified due to the thin reed wing described above, it tends to be overlooked in synergy with the high loom rotational speed.
上記問題を解決するため、実開昭62-129085号公報に

の背面に係止している。In order to solve the above problems, a mounting structure of a reflecting plate for a weft detection feeler, which is disclosed in Japanese Utility Model Laid-Open No. 62-129085, has been proposed. As shown in FIG. 5, this is a thin piece, and the surface under the irradiation light of the weft detection feeler 22 corresponds to the shape of the weft flight path 4 of the reed wing 3 and the left and right ends of the reflection plate 21 which is closely attached to the reed wing 3. The bent portion is bent toward the back side of the reed wing, and the hook-shaped portion 21a is formed at the tip of the bent portion.
Is locked to the back of the.

ができないという問題があった。However, in the reflection plate 21 described above, the hook-shaped portion 21a is locked to the reed blade 3 formed in a thin piece shape only at two positions. Therefore, when the reed blade 3 vibrates, the reflection plate 21
The whole is apt to vibrate, and therefore, there is a problem that the detection operation of the presence or absence of the weft cannot be reliably performed due to the disturbance of the reflection signal due to the vibration of the reflector.

Is a reflective plate that reflects the detection signal output from the weft detection feeler, adheres closely along the shape of the weft flight path,
A weaving machine configured to detect the presence or absence of wefts by a reflected signal that changes depending on the presence or absence of wefts on a weft flight path. A pressing plate to be pressed by the reed wing is attached to the leg plate, and pressing means for pressing the pressing plate to the back of the reed wing is provided between the leg plate and the pressing plate. I am taking means.
