The specific embodiment of invention
Fig. 1,2 illustrates crimping unit 2 of the present invention is disposed at example on the loom (shuttleless loom) 1.Weaving end and weft yarn that crimping unit 2 is located at the wefting insertion side arrive the weaving end of side, and then under several woven situations, also can be located between fabric and the fabric, and Fig. 1 only illustrates the crimping unit 2 that weft yarn arrives side.This crimping unit 2 be furnished with block 3, with this block 3 for the gripping nozzle 12 of one, to the first flanging nozzle 18, the air-supplied feeder 4 of the second flanging nozzle 19, wherein block 3 is arranged between the fabric end 31 of the cutter 7 that is used to cut off weft yarn 16 and fabric 5.In addition, be provided with injector (エ ジ エ Network ) 39, so that suck the cut-out end of the weft yarn 16 that cuts off by cutter 7 across cutter 7 and at the opposition side of block 3.
Have, aforementioned slots 9 wall 17 within it has the first flanging nozzle 18 again.In addition, be positioned at the block 3 of fabric end 31 sides outer wall, clip and have two second flanging nozzles 19 on the slit 9.These two second flanging nozzles 19 clip slit 9 from reed 8 sides, and are splayed ground perforation block 3, and the center line of its nozzle bore prolongs also reports to the leadship after accomplishing a task in opening 34.And one first flanging nozzle 18 and two second nozzles 19 are accepted the supply of air respectively from feeder 4 through the first flanging pipeline 26, the second flanging pipeline 27.
Fig. 3 illustrates the jet control system of crimping unit 2.Among Fig. 3, feeder 4 is made of pressure air source 20, pressure regulator 21a, 21b, switch valve 22,23,24, switch valve control device 25.Pressure air source 20 is connected to through pressure regulator 21a, switch valve 22, gripping pipeline 15 and grips on the nozzle 12, simultaneously, through pressure regulator 21b branch, be connected on the first flanging nozzle 18 by switch valve 23, the first flanging pipeline 26, also be connected respectively on the second flanging nozzle 19 by the second flanging pipeline 27.Switch valve control device 25 comes switch switch valve 22,23,24 according to being connected to loom main shaft angular signal that the encoder 29 on the loom main shaft 28 sends and the injecting time of being set by main control unit 35, and then control grips the jet of nozzle 12, the first flanging nozzle 18 and the second flanging nozzle 19.
During wefting insertion, weft yarn 16 is introduced in the opening 34 of warp thread 33 formation, and the weft yarn 16 that is introduced into is beaten up by reed 8, squeezes into the fell 6 of fabric 5.At this moment, weft yarn 16 has entered in the slit 9, and its front end is cut off device 7 and cuts off.The yarn end of cut weft yarn 16 is attracted by injector 39, to carry out waste disposal.After this, during next wefting insertion, crimping unit 2 is jet successively by gripping nozzle 12, the first flanging nozzle 18, second crimping unit 19, and makes it carry out the flanging action by this air flow, in the opening 34 when the weft yarn termination 37 and the air flow of the weft yarn 16 that is introduced into together folds into next wefting insertion.
Fig. 4 be when the action of normal flanging is shown each nozzle corresponding to the time diagram of the jet time of loom main shaft corner.When normal flanging moves, it is jet to air flow hand-hole 14 at preset time to grip nozzle 12, form first air flow 30, thus, behind the wefting insertion, introduce in the air flow hand-hole 14 the weft yarn termination 37 of the weft yarn 16 that is cut off by cutter 7 in slit 9, thereby grip on the position of slit 9, air flow hand-hole 14.
Then, from gripping the injection (forming first air flow 30) of nozzle 12, through behind the preset time, the first flanging nozzle 18 is jet to reed 8 sides, formation is as the second air flow 32a of second air flow, 32 parts, and then since the injection (forming the second air flow 32a) of the first flanging nozzle 18, through behind the preset time, the second flanging nozzle 19 is jet in the opening 34 of warp thread 33, formation folds into weft yarn termination 37 in the opening 34 of warp thread 33 thus as the second air flow 32b of second air flow, 32 parts.So crimping unit 2 is by carrying out flanging in the opening 34 that weft yarn termination 37 is folded into warp thread 33.
The formation of first air flow 30 is except from gripping the air flow that nozzle 12 sprays, also except the air flow that can attract by the attraction mouth of air flow hand-hole 14 form, also can form by a plurality of different air flows.
In addition, second air flow 32 is removed the attraction form and the air flow that only sprayed by jet forms.Be preferably, second air flow 32 is formed by air flow 32a, the 32b of the different a plurality of injections of direction as this embodiment, its flanging efficient height, but also can form by an air flow.Further, even a plurality of in this embodiment air flow makes the injecting time difference, also can make up.
Fig. 5 be when flanging former by staplings thereby that cause being shown being failure to actuate each nozzle corresponding to the time diagram of the aerojet time of loom main shaft corner.Because wefting insertion is bad as short latitude, when weft yarn 16 did not arrive the position of weft yarn detecting sensor 36, weft yarn detecting sensor 36 failed to detect weft yarn 16, and staplings sends the Weft stop signal as stop reason to main control unit 35.Main control unit 35 1 receives filling broken signal, just switch control valve device 25 is sent the switch motion inhibit signal of switch valve 23,24.Switch valve control this moment device 25 grips the injection of nozzle 12, but allows switch valve 23,24 keep closed condition, and forbids the aerojet of the first flanging nozzle 18 and the second flanging nozzle 19.In addition, the injection that grips nozzle 12 is longer than common period, when for example the injection when the second flanging nozzle 19 is common is over.The same during with normal wefting insertion, cutter 7 cuts off the weft yarn in the slit 9 16 after beating up.
The action of weft yarn 16 in the slit 9 of block 3 when Fig. 6 shows flanging and is failure to actuate.By reed 8 beat up enter weft yarn terminations 37 in the slit 9 and cut off by cutter 7 after, be inserted in the air flow hand-hole 14 by effect from first air flow 30 that grips nozzle 12, be pulled simultaneously and be held in the air flow hand-hole 14.After this, switch valve control device 35 allows gripping nozzle 12 stop jet.
Like this, switch valve control device 25 is according to the instruction from loom 1, Weft stop corresponding to the stop reason that becomes loom 1, end the opening of switch valve 24 of the switch valve 23 of the first flanging nozzle 18 and the second flanging nozzle 19, do not form second air flow 32 (32a, 32b), thereby weft yarn termination 37 is stayed in the air flow hand-hole 14, does not carry out flanging.Even stop from first air flow 30 that grips nozzle 12, weft yarn termination 37 yet remains in the air flow hand-hole 14.
Like this, by second air flow 32 (32a, 32b) is failure to actuate fully flanging is failure to actuate, but when this flanging was failure to actuate, second air flow 32 (32a, 32b) both sides or either party can exist in fact and can not exist by air flow flanging, that degree is more weak.Therefore, the meaning of " second air flow 32 (32a, 32b) is failure to actuate " must be interpreted as, and except that being failure to actuate fully, in fact also containing and can not cause flanging, the more weak air flow existence of degree.In addition, as this embodiment, under the situation that second air flow 32 is formed by a plurality of air flows, only the injection of a side second air flow (as 32b) is failure to actuate to forbid its injection, and only the opposing party's second air flow 32 (as 32a) can not allow weft yarn termination 37 fold in the openings 34, and second air flow, 32 integral body become and are failure to actuate in fact.Therefore, the meaning of " second air flow 32 (32a, 32b) is failure to actuate " is, under the situation that second air flow 32 is formed by a plurality of air flows, except that whole second air flows are failure to actuate fully, also contains the situation that portion of air stream only is failure to actuate.
Because this flanging is failure to actuate, the operator allows loom 1 reverse after loom 1 stops, and in fell 6 pick findings (mouth goes out), will not extracted from the fell 6 of fabric 5 by the defect latitude 16 of flanging.
Though not shown, when defect latitude removal device was located at the wefting insertion side, this defect latitude removal device was accepted from operator's the indication or the instruction of loom 1, defect latitude 16 is introduced in this device, and defect latitude 16 is automatically removed from the fell 6 of fabric 5.Owing to can easily remove defect latitude 16 by this device, thereby defect latitude 16 moves to cutter by the effect from the air flow of special nozzle and cuts off outside the zone between the fabric 5 of unshowned Weft insertion nozzle and wefting insertion side, or by cutter is failure to actuate, it is motionless to be retained as the former state that links to each other with weft yarn 16 in the Weft insertion nozzle.
In addition; under the situation of this embodiment; owing to other shut down reason; as warp stop motion, manually stop etc.; crimping unit 2 sprays first air flow 30 according to the injecting time that Fig. 4 is scheduled to by gripping nozzle 12 usually; spray second air flow 32 (32a, 32b) by the first flanging nozzle 18 and the second flanging nozzle 19, thereby carry out the flanging action.
Each nozzle jet time corresponding when then, Fig. 7 flanging that another embodiment of the present invention is shown is failure to actuate with the loom main shaft corner.The method that the shuttleless loom flanging is failure to actuate among the embodiment shown in Figure 7 is; according to instruction from loom 1; the shutdown reason of corresponding loom 1; at least spraying in second air flow 32 (32a, 32b) by the first flanging nozzle 18 and the second flanging nozzle 19; spray first air flow 30 by gripping nozzle 12, the weft yarn termination in the slit 9 37 is not folded in the opening 34 of warp thread 33.
When main control unit 35 is accepted the Weft stop signal, open valve signal to switch valve control device 25 output resumes, switch valve control device 25 makes switch valve 22 keep open mode in the time when being longer than regular event, at least spraying in second air flow 32 (32a, 32b) by the first flanging nozzle 18 and the second flanging nozzle 19, spraying first air flow 30 by gripping nozzle 12.In addition, the valve of opening of the switch valve 24 of opening the valve and the second flanging nozzle 19 of the switch valve 23 of the first flanging nozzle 18 carries out in same time with the action of common flanging the time, thereby forms second air flow 32 (32a, 32b).
The state of weft yarn 16 in the slit 9 of block 3 when Fig. 8 is illustrated in embodiment flanging shown in Figure 7 and is failure to actuate.Beat up by reed 8, weft yarn termination 37 is entered in the slit 9, after this weft yarn termination 37 is cut off device 7 cut-outs, by effect from first air flow 30 that grips nozzle 12, enter in the air flow hand-hole 14, simultaneously with its traction, be held in the air flow hand-hole 14.Last till always that from first air flow 30 that grips nozzle 12 second air flow 32 (32a, 32b) from the first flanging nozzle 18 and the second flanging nozzle 19 finishes, thereby, weft yarn termination 37 can be by flanging even form second air flow 32 (32a, 32b) owing to being subjected to 30 tractions of first air flow, gripping and stay in the air flow hand-hole 14 yet.
At this moment, the effect of expulsion pressure that is subjected to second air flow 32 (32a, 32b) for weft yarn termination 37 is not by flanging, be preferably, expulsion pressure from first air flow 30 that grips nozzle 12 is higher than usually, perhaps, weaken the expulsion pressure of second air flow 32 (among 32a, the 32b particularly 32a), weft yarn termination 37 can more firmly be stayed in air flow hand-hole 14, thereby prevents by flanging.In addition, if shorten the injecting time of second air flow 32 (32a, 32b), the duration of first air flow 30 also can shorten, thereby just can prevent the temporary reduction of pressure air source 20 air pressure.
Like this; according to instruction from loom 1; shutdown reason (Weft stop) corresponding to loom 1; switch valve control device 25; at least the opening in the valve of the switch valve 23,24 of the first flanging nozzle 18 and the second flanging nozzle 19, allow the switch valve 22 that grips nozzle 12 drive valve, so even form second air flow 32 (32a, 32b); weft yarn termination 37 also can be stayed in the air flow hand-hole 14, and can be by flanging.Therefore, the operator allows loom 1 counter-rotating come pick finding (mouth goes out), thereby can will easily not pulled out from fabric 5 by the defect latitude 16 of flanging.
In this embodiment, because first air flow 30 continues gripping weft yarn termination 37, stop the action of the flanging due to the injection of second air flow 32 (32a, 32b), the operating state of first air flow 30 by making when common is proceeded to realize, action itself does not change, thereby, can be owing to the slow movement of control system by flanging.
In addition, grip weft yarn termination 37 by first air flow 30, prevention is by the action of the flanging due to the injection of second air flow 32 (32a, 32b), needn't be with weft yarn termination 37 introducing air flow hand-holes 14 are interior so that the action that grips is mutually continuous, first air flow 30 that is later than when common at second air flow 32 (32a, 32b) finishes under the inchoate situation, perhaps under temporary transient situation of interrupting, stop the action of flanging also can interrupt midway.And embodiment as shown in Figure 7 continue to form first air flow 30 up to second air flow 32 (32a, 32b) preferred example when being over.In this case, grip weft yarn termination 37 by first air flow 30, hinder the action of the flanging due to the injection of second air flow 32 (32a, 32b), continue to be realized by the operating state that makes common air flow, can not allow switch valve 22 move midway, thereby having can be owing to slow movement by the advantage of flanging.
The effect of invention
According to technical scheme 1, if shut down reason Weft stop etc., need to be with the defect latitude from fabric Fell when pulling out, according to the instruction from loom, can not spray for folding into the weft yarn termination Air stream, and make the weft yarn termination not by flanging, thereby can easily the defect latitude be removed from fabric. Particularly, (1) owing to be failure to actuate the action that the weft yarn termination is folded in the Warp opening, thereby, Do not worry that the weft yarn termination is by the mistake flanging; (2) injection of air stream is because after weft yarn grips, Can there be the sufficient time to be tackled for the instruction from loom; (3) jet be failure to actuate logical Cross the non-action state that makes injection and proceed to realize, can not change this state therebetween, thereby, Can be owing to change slow movement and by flanging, thus the weft yarn termination conscientiously can be by flanging.
