Abstract

The invention relates to the technical field of air jet looms, discloses a weft yarn detection device on an air jet loom, and particularly relates to the weft yarn detection device and a use method thereof. The weft yarn detection device comprises an edge folding jet tube, a circuit board assembly and a weft detection device. The weft detection device comprises a long weft detection photoelectric assembly and a short weft detection photoelectric assembly, the long weft detection photoelectric assembly comprises a photoelectric transmitting tube and a photoelectric receiving tube, and the short weft detection photoelectric assembly comprises a second photoelectric transmitting tube and a second photoelectric receiving tube. The structural design is reasonable, the weft detection device is placed outside a tunnel reed or a weft insertion confuser and moves along with the edge folding jet tube together, a weft suction channel and a weft insertion channel are narrow, and the movement range of weft yarn is controlled, so that the detection of photoelectric elements on the weft yarn becomes easy and reliable; moreover, the waste of edge folding weft yarn is also reduced, the quality of cloth cover and the accuracy of weft detection are improved, and the defect that a jet and suction tube edge folding device cannot detect the weft yarn is overcome.

Description

technical field [0001] The invention relates to the technical field of air-jet looms, in particular to a weft yarn detection device and a use method thereof. Background technique [0002] At present, the weft detecting device of the air-jet loom is divided into three types according to the installation method: the front type, the buckle type and the embedded type. The three methods are to install the weft detector on the steel buckle and move together with the steel buckle. The weft detection device uses the infrared reflection of the weft itself to detect the infrared light, so the technical requirements for the accuracy of the weft detection head are relatively high. In addition to the background interference of the special-shaped button, complex signal processing circuits are required to obtain useful weft signals. The buckle type and embedded weft detection both use photoelectric tube to detect, and use the weft yarn to block the photoelectric signal to obtain an effecti...
