Abstract
The invention relates to a method for weft insertion driving of double-layer hard rapier loom. Based on the foundation of original weft insertion mechanism in single flexible rapier loom, original guide wheel maintained; rigid rapier on the lower layer, which is made of alloy with gear-strip on the up-and-down surfaces or strengthened composite material with carbon fiber takes the place of original flexible rapier. So lower rigid rapier accomplishes weft insertion motion in linear reciprocation when the rack on the lower surface is driven by guide wheel, which is reciprocating, while the upper rigid rapier accomplishes the same weft insertion motion as the lower rigid rapier by the rack on the upper surface of lower rigid rapier and two transitional gears so that it is satisfied that double-layer hard rapier with certain distance in up-and-down arrangement accomplishes linear weft insertion motion in horizontal-transverse direction of loom machine synchronously.
Description
Affiliated technical field
The present invention relates to a kind of Weft insertion method of Rapier looms, especially a kind of method of wefting insertion transmission of double-layer rigid Rapier looms.
Background technology
Woven mode, when especially comparing with knitting type, because filling yarn presents more straight state in fabric, use more with in the weaving of the TECHNICAL FABRIC of glass fibre or aramid fiber, the contour performance fibers of carbon fiber, with the advantage of the high-strength and high-modulus that makes full use of these fibers and avoid the shortcoming of easy lousiness, broken yarn as much as possible.
If weaving of enterprising oozy glass fiber of fly-shuttle loom or carbon fiber, the operation of shuttle produces stronger abrasive action to not wear-resisting glass fiber warps, makes the warp thread fluffing, influences product quality.
If weaving of enterprising oozy glass fiber of flexible rapier loom or carbon fiber, then must install run through the view picture loom lead the guide rail of sword sheet as flexible sword belt weft guiding operation.Have the operation of the sword belt of leading the sword hole and lead the sword sheet the interspersed effect of lower layer warp yarns is produced stronger abrasive action to not wear-resisting glass fiber warps, make the warp thread fluffing, had a strong impact on product quality.
Just the part Rapier looms should be glass fibre or the optimum type of carbon fiber weaving.Just part arrow shaft is to be made of a bigger elongate rod and a sword head of composite bending modulus, and arrow shaft is generally made with alloy in lightweight or carbon fibre composite.The gripper head sectional dimension is little, has created condition for reducing the Warp opening height, and is very favourable to the glass fibre processing of low elongation.In addition, arrow shaft is suspended in the shed open and moves in the wefting insertion process, does not need to be provided with specially the device of guiding arrow shaft in the shed open, does not rub with warp thread.This just can play a good protection to warp thread.But in the market, because the rigid rapier mechanism complexity that specialized designs is made, price is higher, for example the rigid rapier weaving machine of road Neil (DORNIER).
A developing direction of the woven fabric of the high-performance fiber that industry is used is to weave complex organization, for example double-deck or integrated spaced woven fabric.This kind fabric effective and high-quality weaves machine on weaving principle and efficient, product quality, should be the double-layer rigid Rapier looms.Such loom adopts double-layer shed opening mode, and each wefting insertion is introduced each weft yarn up and down simultaneously.But, existing specialized designs is made the double-layer rigid Rapier looms, and the double-layer rigid Rapier looms of Van Der Veer (VAN DE WIELE) for example is though satisfied the requirement of double-layer rigid wefting insertion well, but machine manufacturing and acquisition cost are more higher than the loom of single secondary rigid rapier.
Summary of the invention
In order to overcome above-mentioned Flexible Rapier in Inserting Weft in the deficiency of weaving on the high-performance fiber; and the too high deficiency of cost of purchasing the double-layer rigid Rapier looms; the invention provides and a kind ofly on the flexible rapier loom that generally uses, can utilize existing rapier transmission mechanism to carry out the implementation of double-layer rigid rapier weft insertion mechanism as much as possible; this mode has not only been cancelled and has been led the sword hook and to the friction of warp thread; wefting insertion when having realized two secondary arrow shafts; and on existing flexible rapier loom, realize simple; reduced production cost, be convenient to popularize and promote.
The technical solution adopted for the present invention to solve the technical problems is: at first, on the basis of original weft insertion device of single secondary flexible rapier loom, keep original guide wheel; The flexible sword belt of former machine use is used lower plane all be the alloy of spline-simulating or the rigid rapier replacement that is in the lower floor position that the carbon fiber reinforced composite is made; Like this, when following rigid rapier is subjected to the transmission of the reciprocal guide wheel that rotates at the tooth bar of its lower plane, carry out back and forth motion of weft-insertion of linearity; Simultaneously, by last plane tooth bar and two transition gear transmissions of rigid rapier down, the rigid rapier that is in the position, upper strata is obtained and the identical wefting insertion of the following rigid rapier characteristics of motion, so satisfied the requirement of the double-layer rigid arrow shaft that is arranged above and below into certain distance at the synchronous linear motion of weft-insertion of loom horizontal cross.
The invention has the beneficial effects as follows, can utilize the weft insertion device of the secondary flexible rapier loom of existing list higher degree, repack the transmission of double-layer rigid arrow shaft as far as possible easily into, satisfy some product at low cost, for example double-deck glass fabric at interval when weaving to the wefting insertion requirement of double-layer rigid arrow shaft.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the mechanism driving schematic diagram of embodiments of the invention.
1. guide wheels among the figure 2. descend rigid rapier, 3. first transition gear, and 4. second transition gear is 5. gone up rigid rapier, 6. guide wheel axle, the 7. first transition gear axle, the 8. second transition gear axle.
The specific embodiment
Fig. 1 is the mechanism driving schematic diagram of embodiments of the invention, has represented transmission principle and process.On the basis of original weft insertion device of single secondary flexible rapier loom, keep original guide wheel 1, replace the flexible sword belt that former machine uses with rigid rapier 2 down; Following rigid rapier 2 is made by the carbon fiber reinforced composite, and lower plane all is spline-simulating on it; The tooth bar a of the lower plane of following rigid rapier 2 is subjected to the transmission of guide wheel 1, tooth bar b transmission first transition gear 3 on last plane, again by first transition gear, 3 transmissions, second transition gear 4, rigid rapier 5 in the final transmission, the relative position of the mandrel 7,8 of the mandrel 6 of guide wheel 1 and transition gear 3,4 remains unchanged; Last rigid rapier 5 is also made by the carbon fiber reinforced composite, but just lower plane is spline-simulating; Because two transition gears the 3, the 4th are isotype with tooth, rotation direction is opposite all the time, so, when original guide wheel 1 back and forth rotates, just make the following rigid rapier 2 and the last rigid rapier 5 of tooth bar form in shed open, realize linear synchronously back and forth motion of weft-insertion, shown in arrow among the figure in unsettled mode.
