System and method for electronic type automatic latitude seeking

Abstract

The invention discloses an electronic automatic weft locating system and a method thereof which are capable of solving above problems. According to first aspect, the invention provides a method for automatically locating the weft on a shuttleless loom. The shuttleless loom comprises a weft inductive sensor, a coiling mechanism, a warp feeding mechanism and an electronic weft feeding mechanism. The method includes the following steps: according to the weft breakage signal from the weft inductive sensor which indicates that the weft is broken, recording the number of the broken weft ; stopping the work of the coiling mechanism and the warp feeding mechanism; retreating the current weft to the prior weft of the broken weft; starting the electronic weft feeding mechanism and checking whether the loom runs to the position of the broken weft; when the broken weft is located, pausing the loom for the convenience of removing the broken weft; and starting up the loom, including the coiling mechanism and the warp feeding mechanism. The electronic automatic weft locating system and the method have high automatization degree and are simple and easy to operate, greatly reduce work intensity of the spinners and lower quality requirement on the spinners, effectively eliminate stop marks and improve the quality of the product.

Description

technical field [0001] The invention relates to a shuttleless loom, in particular to a weft finding system and method in the shuttleless loom. Background technique [0002] At present, after the weft is broken on the popular shuttleless loom, there are two ways to deal with it when the locomotive shifts the stalls: [0003] 1. Rewind the textured paper by hand→jog to find the broken weft shed→remove the broken weft→then manually find the next shed→connect the weft thread→loosen the coiling, manually reverse the woven fabric surface through the gear→tighten the warp yarn → drive normally; [0004] 2. Go forward for a process organization→jog to find the broken weft shed→remove the broken weft→then manually find the next shed→connect the weft thread→loosen the coiling→manually reverse the woven fabric through the gear→close Tight warp → drive normally. [0005] These two methods take a long time, require high quality of the driver, are prone to block errors, leave parking m...

AI Technical Summary

Problems solved by technology

[0005] These two methods take a long time, require high quality of the driver, are prone to block errors, leave parking marks, and have a high rate of defective products.

At present, there are mechanical automatic weft-seeking systems at home and abroad, but their installation is troublesome and costly, which is not conducive to popularization
