The specific embodiment
As shown in Figure 1, be electromagnetism wefting insertion weft carrier of the present invention, comprise shuttle box 1 and the yarn storage device 2 that is positioned at shuttle box 1, shuttle box 1 two corresponding sidewalls are provided with permanent magnet 5 and two locating holes 4 that are respectively equipped with for the electromagnetism wefting insertion.The inwall of locating hole 4 is provided with copper sheathing, is used for preventing the locating hole wearing and tearing, affects locating effect, and the cross section of locating hole 4 is circular.Be respectively equipped with an inside counterbore 3 on corresponding two sidewalls of shuttle box 1, permanent magnet 5 is fixed in the described counterbore 3.The end face of permanent magnet 5 is lower than the outer surface of the sidewall of shuttle box 1.When the cross section of locating hole 4 when being circular, two locating holes need to be set, by 2 points (locating hole 4) simultaneously (end face of permanent magnet 5) fix weft carrier.
In addition, the locating hole 4 on corresponding two sidewalls of shuttle box 1 also can only have one, and the cross section of locating hole 4 can be the polygons such as triangle, quadrangle, pentagon, also can be other shape of avoiding the shuttle box to rotate.When the cross section of locating hole 4 when being non-circular, only need a bit (locating hole 4) simultaneously (end face of permanent magnet 5) fixing weft carrier.
As shown in Figure 2, electromagnetism wefting insertion of the present invention is used arrow shaft, comprise body 11, body 11 1 ends are provided with iron core 13, the free end of iron core 13 is equipped with sword head 12, is tied with coil 14 on the iron core 13, and sword head 12 is provided with two alignment pins 15, the cross section of alignment pin 15 is circular, and the free end end face of iron core 13 is higher than the outer face of sword head 12.
In addition, the alignment pin 15 on the sword head also can be one, and the cross section of alignment pin 15 can be the polygons such as triangle, quadrangle, pentagon, also can be other shape of avoiding the shuttle box to rotate, need to be consistent with the locating hole 4 on the shuttle box 1.
The free end end face of iron core 13 also can be lower than the outer face of sword head 12, and the end face of the permanent magnet of corresponding weft carrier then is higher than the outer surface of weft carrier sidewall, to guarantee the permanent magnetism iron phase adhesive of iron core 13 and weft carrier.
Electromagnetism Weft insertion method of the present invention comprises the steps:
As shown in Figure 3, add the forward electricity for the coil 14 of the first arrow shaft 10, hold weft carrier 20 1 end permanent magnets 5 by iron core 13, and by alignment pin 15 location, the first arrow shaft 10 is moved together with weft carrier 20, simultaneously, the second arrow shaft 30 is from other end relative motion.
As shown in Figure 4, the first arrow shaft 10 and the second arrow shaft 30 are converged in the centre, and the alignment pin 15 of the second arrow shaft 30 injects in the weft carriers 20; At this moment, the coil of the first arrow shaft 10 adds reverse electricity, and the coil of the second arrow shaft 30 powers up, and holds the permanent magnet 5 of weft carrier 20 other ends by iron core 13.
As shown in Figure 5, the first arrow shaft 10 is returned and is cut off the power supply, and simultaneously, the second arrow shaft 30 is together returned with weft carrier 20.Finish wefting insertion one time, during wefting insertion, two arrow shafts actions are exchanged, and repeat the action of last wefting insertion next time.
In addition, the iron core 13 of the first arrow shaft 10 and the second arrow shaft 30 and the permanent magnet 5 of weft carrier 20 be mutually during adhesive, between leave the slit, avoid permanent magnet 5 to be impacted.
During the shuttleless loom wefting insertion, Yi Bian after always from guiding another side into, whenever drawing a latitude, weft yarn all needs weft yarn is cut off, otherwise can't carry out the wefting insertion of next latitude; Because every latitude all will cut off, so selvedge is burr, needs serging device that weft yarn is enwinded, and prevents that the warp thread on the limit from escaping, and forms bad cloth.Shuttle does not allow between two latitudes to cut off with the weft yarn reciprocating motion during electromagnetism Weft insertion method wefting insertion of the present invention, fabric self-assembling formation plain edge, and adjacent two weft yarns are " U " at the selvedge place, the warp thread on the limit can be pinned, and therefore do not need special serging device; Fabric does not have burr, and does not need lock seaming, can improve the utilization rate of weft yarn yet; Especially be fit to be applied in and weave on the more stereo fabric of Weft layers, can cancel loaded down with trivial details serging device and weft accumulator, improve woven efficient and fabric quality.
