Self-adaptive weft catching device

Abstract

The invention provides a self-adaptive weft catching device which comprises an infrared positioning frame arranged at a weft catching end opposite to a loom nozzle, a loom weft catching component and a control module. The infrared positioning frame is arranged in front of the loom weft catching component, an infrared emitting head and an infrared receiving head which are in opposite injection are arranged in the infrared positioning frame, the loom weft catching component is arranged on a two-dimensional moving component, and the control module is electrically connected with the infrared positioning frame and the two-dimensional moving component. The control module transmits position data, of weft, acquired by the infrared positioning frame to the two-dimensional moving component, and the two-dimensional moving component moves the loom weft catching component to the position of the weft for accurate weft catching.

Description

technical field [0001] The invention relates to the field of shuttleless looms, in particular to an adaptive weft catching device for shuttleless looms. Background technique [0002] The common basic feature of shuttleless looms is to separate the weft yarn package from the shuttle, or to carry only a small amount of weft yarn to replace the large and heavy shuttle with a small and light weft insertion device, which provides favorable conditions for high-speed weft insertion . In the supply of weft yarn, the bobbin package is directly used, and it enters the weft insertion mechanism through the weft storage device, so that the loom gets rid of the frequent weft filling action. Therefore, the use of shuttleless looms is of great significance for increasing fabric varieties, adjusting fabric structure, reducing fabric defects, improving fabric quality, reducing noise, and improving working conditions. The speed of shuttleless looms is high, and the efficiency is usually 4-8 ...

AI Technical Summary

Problems solved by technology

[0003] Since the shuttleless loom does not have a shuttle to guide the weft yarn to fly in the shed, and the weight of the weft yarn itself is very light, the weft yarn is easily disturbed by air resistance, impurities or gravity during the transmission process. The predetermined weft insertion coordinates are relatively inaccurate during installation. Once the allowable error range of the weft catcher is exceeded, it is easy to cause weft detachment accidents.
