Fig. 1 represents that loom when running weft yarn Y's gives the yarn path.Weft yarn cheese 1 and wear weft yarn with between the main burner 13 give that weft yarn Y is cut off by mistake on the yarn path time, by yarn break sensor 5, the weft detector (not shown) relative with main burner 13 that be clipped in the middle of maybe will weaving cotton cloth detects this broken yarn (step 1 of Fig. 7 is hereinafter to be referred as S1.Other step is analogized).Computer C was according to sending the base stop signal to the loom control computer to the yarn fault detection signal, and the loom control computer sends the base halt instruction according to this signal.According to this instruction, the weft yarn of wearing on the fuse stops on the position before the reed action with main burner 13.
After base stops, this base specified amount that falls back, the weft yarn of wearing on the fuse stops (S2) with main burner 13 on the position of falling back at last (position of entrying) of shaking the zone.In addition, after base fell back, electromagnetic valve V3 and solenoid 7 were by excitation, and air sprays from discharge nozzle 15.Simultaneously, arresting lever 7a is from separating (S3, S4) around yarn face 66.Then, electromagnetic valve V2 is by excitation, air from yarn-feeding guiding nozzle 4, be blown into nozzle 9 and extradition nozzle 17 sprays (S5).
Below, as shown in Figure 2, the yarn treatment state of weft yarn Y under quilt mistake cut-out situation between weft yarn cheese 1 and the Weft yarn clock measuring 6 is described.
Weft yarn Y cuts off head (residual yarn) Y ' and is wound on yarn face 6b under situation about cutting off between weft yarn cheese 1 and the Weft yarn clock measuring 6, and, under the state before weft yarn usefulness main burner 13 is worn in arrival, remain in on the yarn path.At this moment, as previously mentioned, because arresting lever 7a is from separating around yarn face 6b, so the residual yarn on yarn face 6b discharges from arresting lever 7a and comes.So, when air sprays from discharge nozzle 15, cut off a Y ' and just be rejected in the disposal box 14 with this air.
In addition, as shown in Figure 2, because yarn does not have break-through yarn-feeding guiding nozzle 4, so yarn break sensor 5 detects no yarn (S6).Detect according to this, electromagnetic valve V1 by excitation the time of appointment, air has sprayed the time (S7) of appointment from exchange nozzle 3.Utilize this aerojet effect, be blown into the top loose thread Y1 of preparation cheese 2 in the yarn-feeding guiding nozzle 4 after, utilize yarn-feeding guiding nozzle 4 and be blown into the aerojet effect of nozzle 9, weft end Y1 is inserted in the bobbin 6a.The top loose thread Y1 that inserts in the bobbin 6a utilizes the aerojet effect of extradition nozzle 17 to be blown in the importing seat 11, and then, as shown in Figure 3, the jet action that utilizes discharge nozzle 15 again is to disposal box 14 guiding.
After electromagnetic valve V1 is encouraged the time of having leveled appointment with a roller, electromagnetic valve V2 demagnetization, yarn-feeding guiding nozzle 4, be blown into nozzle 9 and the extradition nozzle 17 stop injection air (S8).The top loose thread Y1 of preparation cheese 2 imports in the disposal box 14 as shown in Figure 3 with being bent, and, owing to air sprays from discharge nozzle 15, so, make top loose thread Y1 have suitable tension force.Under this state, electromagnetic cutting knife 10 actions, as shown in Figure 4, top loose thread Y1 is cut off (S9) between yarn-feeding guiding nozzle 4 and weft yarn ingress pipe 8.
After top loose thread Y1 is cut off, electromagnetic valve V3 demagnetization, discharge nozzle 15 stops injection air (S10).After stopping injection air, electromagnetic valve V4, V5, V6, V7 be by excitation, air from middle nozzle 12, wear weft yarn and spray (S11) with main burner 13, wind pushing nozzle 18,22.Then, electromagnetic valve V2 is by the time of excitation appointment, air from yarn-feeding guiding nozzle 4, be blown into the time (S12) that nozzle 9 and extradition nozzle 17 spray appointments.
The air that sprays from yarn-feeding guiding nozzle 4, the new cut-out loose thread Y2(of the weft yarn that cuts off facing to electromagnetic cutting knife 10 along the direction of giving the yarn path is referring to Fig. 4) blow.Therefore, cutting off loose thread Y2 can not be bent to the U word shape and wear and see off.Therefore, cut off loose thread Y2 and be subjected to yarn-feeding guiding nozzle 4 in proper order, be blown into the effect of nozzle 9 and extradition nozzle 17, the loose thread break-through intermediate noxzzle 12 of this linearity.Then, cut-out loose thread Y2 begins directive from loose thread and wears weft yarn main burner 13, and enters its inside.Therefore, from preparation cheese 2 weft yarn of drawing reliably break-through wear weft yarn and improved significantly with the ratio existing apparatus of main burner 13.
Break-through is worn weft yarn with the aerojet effect that the cut-out loose thread Y2 of main burner 13 utilizes wind pushing nozzle 18, is blown into weft yarn and imports in the ventilating duct 19, and pass through between driving wheel 24 and the follower 26 and weft detector 20, in the arrival suction tube 21.
Air from yarn-feeding guiding nozzle 4, be blown into nozzle 9 and extradition nozzle 17 and spray the time of appointments after, electromagnetic valve V1, V4～V7 demagnetization (S13).Thereupon, come self-supporting yarn exchange nozzle 3, intermediate noxzzle 12, wear weft yarn and also stop injection with the air of main burner 13, wind pushing nozzle 18,22.
Arriving suction tube 21 interior cut-out loose thread Y2 becomes the detected object of weft detector 20.When weft detector 20 detected weft yarn, electromagnetic valve V7, V8 were by excitation (S14, S15).Thereupon, air sprays from wind pushing nozzle 22.In addition, cylinder 25 begins action, and follower 26 is pressed on the driving wheel 24.Be used to aerojet, in suction tube 21, produce attraction, as shown in Figure 5, cut off loose thread Y2 and in ventilating duct 19, be tightened up from wind pushing nozzle 22.Therefore, under this state, weft yarn is clamped between roller 24 and 26.
Through time of appointment, weft detector 20 detects under the situation about existing less than weft yarn (S14, S16), solenoid 7 demagnetizations, arresting lever 7a with contact (S17) around yarn face 6b.After this, warning device 27 actions (S18).
As previously mentioned, after roller 24 and 26 is bonded together, solenoid 7 demagnetizations, arresting lever 7a with contact (S19) around yarn face 6b, after the contact, motor M is rotated specified amount, makes bobbin 6a around rotating specified amount (S20) around yarn face 6b.Thereby make weft yarn on yarn face 6b, refund to preparation specified amount.
After weft yarn was refunded, weft yarn was drawn motor 23 and is driven, and utilized roller 24 and 26 that weft yarn is cut off loose thread Y2 tension and sends into suction tube 21 interior (S21).At this moment,, utilize and to wear weft yarn and weft yarn Y is cut off with the fixed blade 13a on the main burner 13 according to the tension force that produces among the weft yarn Y, weft yarn Y with wear weft yarn and separate with main burner 13.This cut-out head is rotated further by roller 24 and 26, is admitted in the suction tube 21, simultaneously, utilizes the aerojet effect of wind pushing nozzle 22 to arrange in the into not shown disposal box.Therefore, can be for knitting a circulation from the front end of main burner 13 to the weft yarn Y on the weft path of arresting lever 7a.
When the whole cut-out head of weft yarn passed through weft detector 20, weft detector 20 just detected and does not have weft yarn (S22) in the ventilating duct 19.So the action that weft yarn is drawn motor 23 stops (S23).Then, electromagnetic valve V7, V8 demagnetization, follower 26 separates with driving wheel 24, simultaneously, stops to spray (S24) from the air of wind pushing nozzle 22.After this, base moves on the start position, the base starting.
More than, illustrated that broken yarn occurs in the situation between weft yarn cheese 1 and the Weft yarn clock measuring 6.In addition, under the situation when broken yarn occurs in Weft yarn clock measuring 6 and wears between the weft yarn usefulness main burner 13, handling the action of not carrying out S7 shown in Figure 8 in the action to yarn.Promptly at this moment pass through yarn break sensor 5, so electromagnetic valve V1 is excitation not by weft yarn.Therefore, in order to exchange the cheese of use, be failure to actuate to yarn exchange nozzle 3.
At Weft yarn clock measuring 6 with wear weft yarn with after broken yarn taking place between the main burner 13, weft yarn is by under the situation of intermediate noxzzle 12, and the residual yarn on yarn face 6b utilizes the effect of discharge nozzle 15 to arrange in the disposal box 14.Weft yarn is by under the situation of intermediate noxzzle 12, utilize the air that blows out from bobbin 6a with residual yarn from getting rid of around yarn face 6b.Utilize the aerojet effect of extradition nozzle 17 that residual yarn is blown into again and import in the seat 11, utilize the aerojet effect of discharge nozzle 15 to arrange in the disposal box 14.After discharging the residual yarn of this coiling, electromagnetic cutting knife 10 actions.Therefore, though broken yarn occur in Weft yarn clock measuring 6 and wear weft yarn with between the main burner 13 where, weft yarn can utilize electromagnetic cutting knife 10 to trim, the loose thread that trims feeds intermediate noxzzle 12 and wears weft yarn with in the main burner 13.
Above a series ofly handle action,, can both arrange in the disposal box 14 by importing seat 11 and discharge pipe 11a go up the residual yarn of reeling around yarn face 6b no matter broken yarn occurs in to where the going up of yarn path to yarn.Promptly, the reel eliminating of residual yarn, normally be used to aerojet from discharge nozzle 15, arresting lever 7a and separating around yarn face 6b, and, be equal to from yarn-feeding guiding nozzle 4, the aerojet that is blown into nozzle 9 and extradition nozzle 17 that a kind of treatment process carries out for 11 extraditions that weft yarn guide is taken a seat.Therefore, compare with determine whether the situation of getting rid of residual yarn according to break point of thread, handling procedure can be simplified.In addition, determine the weft detector of whether getting rid of residual yarn to become unwanted.And the residual yarn that will not reel is backed on the weft yarn cheese 1 from Weft yarn clock measuring 6, perhaps needn't get rid of with main burner 13 by wearing weft yarn.Therefore, with weft yarn again to Weft yarn clock measuring 6 or wear that weft yarn causes with main burner 13 break-through handle failure to yarn and will reduce, make the success rate raising of handling to yarn.
As mentioned above, no matter broken yarn occurs in weft yarn cheese 1 and wears weft yarn with where going up between the main burner 13, can both reliably the weft yarn break-through be worn weft yarn main burner 13.
The present invention is not limited to the foregoing description certainly, for example, omits the extradition nozzle 17 and the guide plate 16 of the foregoing description, and is provided with the front end of bobbin 6a to such an extent that point to the inlet that imports seat 11 and also be fine.If utilize this structure, make the injection air that is blown into nozzle 9 directly blow into the inlet that imports seat 11 from bobbin 6a, weft yarn is penetrated from Weft yarn clock measuring 6, pierce in the importing seat 11.
In addition, omit the aerojet effect that is blown into nozzle 9 and only depends on yarn-feeding guiding nozzle 4, also be fine in the top loose thread insertion Weft yarn clock measuring 6 with preparation cheese 2.
And then, can also import seat 11 porch at Fig. 1 yarn break sensor is set.At this moment, according to signal, can judge that the weft yarn broken yarn is to occur between Weft yarn clock measuring 6 and the intermediate noxzzle 12, still occur in intermediate noxzzle 12 and wear weft yarn with between the main burner 13 from yarn break sensor.In other words, sent under the situation that the weft yarn signal is arranged, can judge that weft yarn is at intermediate noxzzle 12 and wears weft yarn with cut between the main burner 13 from above-mentioned yarn break sensor.And, only can carry out weft yarn and handle from discharge nozzle 15 jet airstreams.
