Description

The invention relates to the Weaving device twin-rapier loom and on twin-rapier loom, carry out non-technology through the pile fabrics two-layer weave, it is characterized in that on loom, being equipped with simultaneously two-layer or two pairs of weft insertion rapier up and down, be furnished with and form the shedding mechanism of two-layer shed open up and down, and " fore-telling " shape profiled steel reed is housed, it is characterized in that on the reed face of reed, there are the bearing-surface shuttle race or the flexible rapier of the last sword operation of a double-deck arrow shaft of confession to walk the sword track, so that last sword steadily and successfully drew the upper strata shed open to weft yarn in weaving process, all twin-rapier loom or duplex twin-rapier looms with eigen all can adopt the two-layer weave technology to carry out double width or several are weaved.Adopt technical solution of the present invention, can be on the basis of existing any type fly-shuttle loom and Rapier looms, by former machine or old machine are transformed, be transformed into twin-rapier loom, also can on the basis that existing any type loom is made, pass through Transform Type design, manufacture the new machine of double-deck arrow shaft, be used for two-layer weave, can on a loom, be made into two width of cloth or the identical or different solid coloured cloth of four width of cloth color and luster quality up and down simultaneously, stamp blank fabric, multicolour cloth and jacquard fabric.All according to the old machine of feature transformation of the present invention or the new machine of manufacturing, all can utilize the two-layer weave technology to make the efficient or the output of original loom, double on the original basis, do not increase floor space and factory building, do not increasing operation and administrative staff, only dropping under the situation of a small amount of transformation funds thereby reach, obtaining being doubled and redoubled of economic benefit.

Textile industry and textile technology are sciemtifec and technical spheres with long history, textile technology is by leaps and bounds developing always for many years, for improving the production efficiency of loom, be the way of taking to improve the speed of a motor vehicle mostly, each state all drops into substantial contribution development high-speed weaving machine, the efficient loom of novel high speed constantly occurs, broken the speed envelope of fly-shuttle loom, the speed of a motor vehicle reaches more than 400 rev/mins, go into the latitude rate and reach 1000 meters/minute, particularly flexible rapier loom is simple in structure owing to Rapier looms, and floor space is little, is suitable for polychrome to change latitude, applicability is wide, production efficiency is high and be convenient to fly-shuttle loom and carry out characteristics such as improving old machine, so become in the new loom with fastest developing speed, most widely used a kind of type has formed global " arrow shaft heat " upsurge at present.Yet, this in the past good type, only limit to single shed open single layer of woven, though rigid rapier weaving machine has had the double-deck rapier type of double shed, but can only be used for warp thread fluffing through pile fabrics, and being used for non-ly through pile fabrics, Rapier looms particularly flexible rapier loom and jacquard weaving machine and two-layer weave technology thereof with feature of the present invention, the past is beyond example.

Past weaving weft yarn colour changing jacquard fabric, woollen blanket as jacquard weave, sofa cloth, bunting, sheetings, Curtains Fabrics, silks and satins etc., all be to use single shed open fly-shuttle loom or Rapier looms to join the full-jacquard mechanism weaving, because full-jacquard mechanism and weight return comprehensive, limited the raising of the speed of a motor vehicle, the speed of a motor vehicle is slow, efficient is low, because the member of numerous and jumbled full-jacquard mechanism is (as card, cylindrical fireworks, eedles, griffe, lifting-hook etc.), not only move slow, also be easy to generate unhook, malfunctioning, faults such as failed part, huge harness threading weight is subjected to the influence of acceleration of gravity under the gravity effect, during decline, lifting-hook can not break away from griffing actively to descend, and causes weight to wave and impacts, and causes heald and warp thread lifting untimely and disturb, problems such as the not cleer and peaceful running shakiness of opening appear, so for a long time, the jacquard weaving machine speed of a motor vehicle can not improve always, is in low speed poor efficiency operating condition, this is that the itself condition limits, and depends merely on that to improve that the speed of a motor vehicle raises the efficiency be difficult.In the last few years, advanced country has invented weaving jacquard fabric on the not too high rigidity twin-rapier loom of the speed of a motor vehicle, make into latitude rate or efficient and double, because itself has stiffness rigid rapier, can adapt in the bigger warp thread shed open of tension force and pass through, thus be used for more warp thread fluffing through pile fabrics, and utilize flexible rapier loom weaving weft yarn colour changing jacquard fabric more widely, increase substantially the research of loom efficiency, still do not have breakthrough so far.

The technical development of external non-jacquard weave flexible rapier loom is very fast, be the efficient loom of development novel high speed, the input substantial contribution is not stinted by various countries, Switzerland's salad 500 types, the light research expense is just spent more than 3,500 ten thousand dollars, Belgium Bi Kanuo GTM type, the Italy TP 500 type speed of a motor vehicle all reach 400 rev/mins, yet these advanced looms can't be popularized and be promoted in China in a short time, because this class loom costs an arm and a leg, one of import will be spent tens thousand of U.S. dollar exchanges, it is exactly the TP500 type that Shanghai produces, every price is also up to 16～180,000 yuan, this is that general producer is difficult to purchase, moreover this class loom mostly is the electronics technology that adds at a high speed, the skill level height, general spinning technique of China and yarn qualities, also incompatible high speed more than 300 rev/mins, operating personnel and administrative staff's technical merit and quality, also difficult in a short time the adaptation, moreover, the present situation of China's loom manufacturing equipment and technical conditions, still can not extensively make the very high critical component of precision, therefore, under China's existence conditions, can only make a small amount of state-of-the-art loom, and the work that has a large capacity and a wide range should be placed on the motor reconstruct of keep off a car in the manufacturing speed and the new machine of technology and existing equipment, twin-rapier loom and weaving technology that especially suitable employing has feature of the present invention, it promptly has the not too high speed of a motor vehicle, can adapt to any cotton that any spinning equipment spun, hair, silk, fiber crops, chemical fiber yarn, have again than original surpass one times go into the latitude rate, efficient and output meet or exceed the level of production of present advanced Rapier looms, product is doubled, can also adapt to present appointed condition, operating technology and managerial skills, low cost of manufacture, low price, be beneficial to penetration and promotion, the advantage of the technical program that Here it is.Moreover, for quickening building of the four modernizations, produce and to quadruple to the weaving end of this century, there is a very big equipment rehabilitation problem, have only partly to upgrade and partly transform the way that progressively solves, fly-shuttle loom is transformed to arrow shaft and twin-rapier loom, be only a shortcut of textile industry technological progress.

Purpose of the present invention, be to adapting to China's national situation, introduce overseas equipment less as far as possible, walk to spend less, the efficient height, on the road of fast, adaptable reform, develop the middling speed high-efficiency double-layer Rapier looms and the two-layer weave technology of unique China characteristic, make into latitude rate and output to be multiplied, economic benefit is doubled and redoubled, and catches up with and surpass the international high standards.

Illustrate, to knit the acrylic fibers jacquard blanket is example, no matter use homemade at present or any type flexible rapier loom of import is joined full-jacquard mechanism, it all is single shed open individual layer rapier weft inserting, the speed of a motor vehicle is all about in the of 120～130 rev/mins, go into about 260 meters/minute of latitude rates, as carry out two-layer weave, under the constant situation of former technical conditions, going into the latitude rate can reach about 520 meters/minute, as adopt in this programme and return comprehensive with spring flowing heald replacement weight, or knit plain color fabric or drapery with the heald frame harness threading, the speed of a motor vehicle can be brought up to more than 160～200 rev/mins, going into the latitude rate can be up to more than 640～800 meter/minute, as with two-layer weave technology popularization to adapting to the woven fabric of high-speed weaving machine, the speed of a motor vehicle is more than 250 rev/mins, go into the latitude rate promptly up to more than 1000 meters/minute, and accommodation is wider, as long as can adapt to woven raw material of individual layer Rapier looms and yarn count, garment fabric and drapery, jacquard fabric and non-jacquard fabric, solid coloured cloth and multicolour cloth, also can adapt to twin-rapier loom, it has all advantages of individual layer Rapier looms, as promoting in the whole country, to save a large amount of foreign exchanges and fund for country, create great economic benefit and wealth, to promoting the technological progress of China's textile industry, also be of great importance.

Feature according to equipped " fore-telling " shape profiled steel reed of the present invention, can be on any double-deck fly-shuttle loom and Rapier looms, carry out non-two-layer weave through nap fabric, also can be on existing individual layer fly-shuttle loom and Rapier looms basis, change into the individual layer shed open double-layer shed, individual layer throwed a spear change bilayer into and throw a spear, or change individual layer arrow shaft into double-deck arrow shaft, carry out non-two-layer weave through nap fabric, reversing over double shed fly-shuttle loom and Rapier looms can only be used for limitation through nap fabric, double shed is weaved be widely used in any fabric, when promptly not being equipped with " fore-telling " type profiled steel reed, can carry out two-layer weave through nap fabric, be equipped with when going up " fore-telling " type profiled steel reed, can carry out all non-two-layer weaves through nap fabric.

For ease of implementing, with the technical scheme of feature of the present invention,, be example now with the flexible rapier jacquard weaving machine in conjunction with each transformation partly, be illustrated with embodiment and accompanying drawing.

The transformation of shedding mechanism and feature are that single shed open is changed into double shed, promptly transform heald and harness threading mode, and heald can adopt special eyes heald, also can adopt inclined to one side eye heald, and two inclined to one side eye healds replace an eyes heald.Two harness eyes up and down of eyes heald, penetrate bilevel warp thread respectively, the eye heald then is upward inclined to one side eye and inclined to one side down warp thread that penetrates levels separately partially, use the eyes heald can reduce the heald use amount of half, the distance of two harness eyes of eyes heald is decided on open height, generally should be greater than 5～10 millimeters of open heights, make through the following warp thread of close big upper strata opening and the last slice warp thread of lower floor's opening and keep some distances, but for through close little warp thread as blanket fabric, two harness eyes distance can be littler, and 80 millimeter get final product.Therefore, the harness eye distance of the harness eye distance of eyes heald and inclined to one side eye heald should become seriation, and 80,90,100,110 millimeters etc., to adapt to different shedding mechanisms.The eyes heald of present embodiment and harness threading mode are seen accompanying drawing 1,2, and double-layer shed formation is seen shown in the accompanying drawing 3.
