Description

Weft detection device for automatic tool corrector using direct sensing sensor made of semiconductor integrated sensor {{DIRECT SENSOR USING THE SEMICONDUCTOR FOR WEFT-STRAIGHTENER}

The present invention simplifies the sensing path in the weft detector in the wood cutter, which can simplify the manufacturing process and eliminate the detection error.

Conventional weft detection window is designed to transmit the light of the incandescent lamp lamp to the fabric to transmit the image through the sensor through the film to detect the twist angle of the fabric with a sensing sensor. In the conventional method, the image collected by the transmitted light is collected through the sensor and passes through several paths that are sensed through the film. It should be narrowed down, but it is difficult to convert the angle to the distance and hold it accurately. In addition, the distance is changed by the vibration during use of the machine, the accuracy may be lowered if the deviation is not corrected every time.

Existing method is to send light through one or many (9-11) detection ports and pass through a film with multiple angle markings centering on the reference angle. In general, it is designed to detect the distal angle as a ratio from 9 to 11).

The conventional method has a limitation in reducing the volume of one sensor, so when all the sensors are placed in one sensor, the size of the sensor becomes larger, and accordingly, when using a light source having a different brightness depending on the position, the detection error becomes large.

In addition, since the width of one yarn cannot be reduced, a film for blocking light must be used.
