あり、これが誤動作の要因となつていた。"Conventional technology" Conventional fluid jet type shuttleless loom (jet loom)
In order to detect whether the weft ejected together with the fluid into the warp opening has been completely inserted over the entire cloth, the received light is determined by whether or not the weft crosses the thin line-shaped light beam emitted from the projector. There is an optical weft detection device that detects whether weft insertion has been performed normally by looking for a difference in the amount. Among these, 1. When using a reflective weft detection device, yarn detection is performed by a change in the amount of reflection when a light beam hits the yarn and is reflected. However, when the loom is operating, the reed blades vibrate due to the rocking motion of the reed and the accompanying fluid jetted from the auxiliary injection nozzle, and in that case, the amount of reflection from the reed blades changes, making it appear as if it were from a thread. Changes may occur, which can lead to malfunctions.

た。2 When using a transmission type weft detection device, a signal similar to a signal from yarn may be generated due to projection due to reed blade vibration, positional shift of the light receiving element, shielding of light by the reed blade itself, or changes in the amount of surrounding reflection. This caused the malfunction.
