System and method for breaking through limitation on single weft insertion quantity of rapier loom

Abstract

The invention belongs to the technical field of textiles, and relates to a system and method for breaking through limitation on a single weft insertion quantity of a rapier loom. The system comprisesa weft stop device, a weft selection mechanism, a weft insertion sword, a guide rail and a holding device, wherein the weft stop device is electrically connected with the weft stop system, the weft selection mechanism is arranged at a station behind the weft stop device, the weft selection mechanism, the weft insertion sword, the guide rail and the holding device work cooperatively, first yarn guide holes are formed in the weft stop device, a plurality of weft selection fingers are arranged on the weft selection mechanism, second yarn guide holes are formed in one ends of the weft selection fingers working in cooperation with the weft insertion sword, a weft stop station is additionally arranged in front of the weft selection mechanism, a weft stop detection mechanism is arranged on the weft stop station and electrically connected with the weft stop system, the plurality of weft selection fingers of the weft selection mechanism comprise single-hole type weft selection fingers and a double-hole type weft selection fingers, and the second yarn guide holes of the double-hole type weft selecting finger comprise a left yarn guide hole and a right yarn guide hole. The system is reasonable in structural design, can enable a rapier loom to insert four or more pieces of weft at the same time for weaving, and thus improves yield in unit time.

Description

technical field [0001] The invention relates to a system and a method for breaking through the limitation on the quantity of weft insertion in a single time of a rapier loom, and belongs to the technical field of textiles. Background technique [0002] At present, the technology of drawing double wefts and three wefts on rapier looms is becoming mature gradually. Said double wefts and three wefts refer to the introduction of two or three weft yarns after weaving to form a shed, and then tighten the weft yarns to form a fabric. For example, the utility model patent No. CN204780065U introduces a double-weft method. This method is to fix one end of the weft yarn, pull the weft yarn through the weft insertion device to form double weft, and then tighten it to form a fabric, while the rapier loom is simultaneously Extend two weft selection fingers to hold the sword head to insert weft to form double weft. This method can also achieve three weft insertion at most. With the develo...

Problems solved by technology

With the development of the textile industry at any time, rapier looms can no longer meet the current demand for weft insertion efficiency by inserting three wefts at a time
