Rapier loom and wefting insertion method thereof

Abstract

The invention discloses a rapier loom and a wefting insertion method thereof. The rapier loom comprises a rack, a battening mechanism, multiple shuttle boxes and left and right wefting insertion mechanisms located on two sides of the rack respectively, the shuttle boxes are located above the battening mechanism, each shuttle box is internally provided with a shuttle, the left wefting insertion mechanism comprises a left rapier and a left driving unit which are connected, the right wefting insertion mechanism comprises a right rapier and a right driving unit which are connected, the left driving unit is used for driving the left rapier to move to grab the shuttle from the shuttle box, put the shuttle back to the shuttle box, extend the shuttle into a shuttle port and exchange the shuttle with the right rapier, and the right driving unit is used for driving the right rapier to move to grab the shuttle from the shuttle box, put the shuttle back to the shuttle box, extend the shuttle intoa shuttle port and exchange the shuttle with the left rapier. By means of the method, automatic wefting insertion of section wefts can be achieved, and the problems of excessively long weft dragging length caused by the section weft insertion of a weft insertion manner and tangling wefts are prevented.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a rapier loom and a weft insertion method thereof. Background technique [0002] The weaving of Kesi, makeup flowers, brocade, bifurcated pipes and related restoration of cultural relics requires the use of weft insertion technology. At present, the weft insertion technology adopted by all kinds of modern looms is the traditional "weft-through" method, that is, when the weft is inserted at the opening of the loom, the weft yarn is drawn from one end of the loom to the other end and runs through the entire width of the fabric. . However, this weft insertion method brings difficulties to the weaving of fabrics that need segmented weft (commonly known as broken weft), and can cause a lot of waste of weft yarn raw materials and energy. [0003] The patent number is ZL200710042827.9, and the Chinese patent titled "Rigid Rapier Loom 1×4 Multi-shuttle Box Mechanism" discloses a rigid...

AI Technical Summary

Problems solved by technology

However, this weft insertion method brings difficulties to the weaving of fabrics that require segmented wefts (commonly known as broken wefts), and will cause a lot of waste of weft yarn raw materials and energy.

[0003] The patent number is ZL200710042827.9, and the Chinese patent titled "Rigid Rapier Loom 1×4 Multi-shuttle Box Mechanism" discloses a rigid rapier loom 1×4 Multi-shuttle box mechanism. When wefting, since the shuttle box is set on the outside (left side) of the loom, it belongs to the "through weft" weft insertion, and the length of the weft yarn dragged out is too long, only double weft can be inserted, the weft yarns are entangled with each other, and the weft yarn raw materials are wasted.
