Figure 10 and Figure 11 are the flow charts that joint is handled control program, and control computer C handles control program according to this joint and implements the joint processing.Below, handle to describe in conjunction with the flow chart butt joint of Figure 10 and Figure 11.
Under the state of weaving cotton cloth, switching valve 33 is in the 1st channel status shown in Figure 1, and the swabbing action of suction machine 34 is prolonged and at suction tube 36.In addition, electromagnetic switch valve 29 is in demagnetizing state, has only the water of water tank 25 to be sent to wefting insertion nozzle 24 by pump 26 pressurizations.
When the parallel Y1 on the parallel bobbin 11 uses up, joint Y3 will pass through from the surveyed area of connecting sensor 13, and connecting sensor 13 detects pass through (being moving of joint Y3) of joint Y3.Fig. 4 illustrates the state after joint Y3 passes through from the surveyed area of connecting sensor 13.This joint Y3 moves detection information, is sent to control computer C.
Control computer C carries out joint Y3 and has or not mobile judgement (step S1).(be "Yes" in step S) when detecting joint Y3 mobile, control computer C stops the action of loom CD-ROM drive motor M, the excitation degaussing control of o 15, the excitation degaussing control of parallel clamper 27, the action of suction machine 34.They stop action will making loom stop (step S2).After loom stops, will be as shown in Figure 4, be in the state that stretches out with the jet 241 of nozzle 24 from wefting insertion with the front end Y11 of the parallel Y1 that passes the nozzle 24 from wefting insertion.
The anglec of rotation of loom for example was 180 ° when in the present embodiment, loom stopped.Though the anglec of rotation of loom is uncertain during the mobile detection information of connecting sensor 13 output, the anglec of rotation of loom for example is made as 320 ° in the time of will controlling computer C and read the mobile detection information of joint Y3.If connecting sensor 13 is when having exported mobile detection information before 320 ° in the loom anglec of rotation, then loom will stop when 180 ° of the next loom anglecs of rotation.If connecting sensor 13 is when also having exported mobile detection information 320 ° after in the loom anglec of rotation, to control computer C and when 320 ° of the next loom anglecs of rotation, read mobile detection information, loom then stops when 180 ° of its next loom anglecs of rotation.In addition, in the present embodiment, when loom stopped owing to detecting moving of joint Y3, joint Y3 was the upstream side that is positioned on the coiling face 142 or is positioned at coiling face 142 on the parallel path.
After loom stopped, control computer C made switching valve 33 be converted to the 2nd channel status, and made suction machine 34 actions (step S3).So, produce suction streams at the tube end of suction cylinder 31 inside of utensil 46 (promptly in conjunction with), be inhaled in the suction cylinder 31 with the parallel front end Y11 that the jet 241 of nozzle 24 stretches out from wefting insertion.In addition, control computer C makes parallel clamper 27 excitations, and makes o 15 excitations (step S4).The excitation of parallel clamper 27 makes parallel clamper 27 be converted to release conditions from clamp position, and parallel Y1 obtains discharging under the clamping action of parallel clamper 27.O 15 excitations make card shotpin 151 break away from from coiling face 142, and the line that is wound on the coiling face 142 obtains discharging under the jam effect of card shotpin 151.That is, become and the line on the coiling face of being wound on 142 can be pulled out from coiling face 142.Parallel Y1 from the card shotpin discharged for 151 times, parallel Y1 from the parallel clamper discharged for 27 times and suction cylinder 31 the swabbing action line that will be wound on the coiling face 142 pull out from coiling face 142.
Secondly, control computer C makes o 45 excitations (step S5).The excitation of o 45 makes clamping wheel 42 leave from clamping wheel 43, obtains discharging under the clamping action of clamping wheel 42,43 at the parallel between clamping wheel 42 and the clamping wheel 43.Fig. 5 and Fig. 6 illustrate the state after clamping wheel 42 leaves from clamping wheel 43.
After clamping wheel 43 left, control computer C made parallel clamper 27 and o 15 degaussings (step S6) at clamping wheel 42.The degaussing of parallel clamper 27 makes parallel clamper 27 be converted to clamp position from release conditions, at storage Weft handling device 14 to wefting insertion with the parallel between the nozzle 24 by parallel clamper 27 clampings.The degaussing of o 15 makes card shotpin 151 be fastened on the coiling face 142.
When being in parallel and being fastened on state on the coiling face 142 by 27 clampings of parallel clamper and card shotpin 151, control computer C makes loom CD-ROM drive motor M carry out both quantitative low speed and reverse (step S7).The low speed and reverse of loom CD-ROM drive motor M makes driving shaft 17 to the opposite spin of arrow R (with reference to Fig. 2), makes the opposite spin of the direction of rotation of bobbin 141 when weaving cotton cloth.Though the 43 also opposite spins of the direction of rotation when weaving cotton cloth of clamping wheel are left because clamping wheel 42 takes turns 43 from clamping, thereby the parallel between the clamping wheel 42,43 can not be pulled parallel bobbin 11,12 1 sides.The parallel that passes from bobbin 141 and arrive parallel clamper 27 ends on card shotpin 151 and being wound up on the coiling face 142 on one side in one checkpost along with bobbin 141 counter-rotatings.So the part of parallel that is positioned at the upstream side of bobbin 141 will be wound up on the coiling face 142.When because loom CD-ROM drive motor M carries out both quantitative low speed and reverse parallel when being wound on the coiling face 142, joint Y3 will store on coiling face 142.Fig. 5 illustrates joint Y3 and stores state on coiling face 142.
In the present embodiment, the both quantitative low speed and reverse of loom CD-ROM drive motor M is the anti-amount that circles of loom.That is be the length of carrying out a wefting insertion, owing to loom CD-ROM drive motor M carries out the length that both quantitative low speed and reverse is wound up into the parallel on the coiling face 142.And, parallel bobbin 11,12, storage Weft handling device 14, storage Weft handling device 14 and wefting insertion are to set like this with the configuration relation of nozzle 24, that is, always the length than the parallel path the heating wire 313 in from the front end of bobbin 141 to suction cylinder 31 is long to the line length bobbin 141 front ends from storing joint Y3 on coiling face 142.
After loom CD-ROM drive motor M carried out both quantitative low speed and reverse, control computer C made parallel clamper 27 and o 15 excitations (step S8).The excitation of parallel clamper 27 makes parallel clamper 27 be converted to release conditions, and the parallel that passes through from parallel clamper 27 obtains discharging under the clamping action of parallel clamper 27.The excitation of o 15 makes card shotpin 151 break away from from coiling face 142, and the line that is wound on the coiling face 142 only obtains discharging under the effect from the card that blocks shotpin 151.Because therefore suction machine 34, will be inhaled in the suction cylinder 31 with the parallel that nozzle 24 extends to suction cylinder 31 from wefting insertion continuing action.So the line that is wound on the coiling face 142 is drawn out from coiling face 142, the joint Y3 that stores on coiling face 142 is inhaled in the suction cylinder 31.State when Fig. 8 illustrates joint Y3 and is inhaled in the suction cylinder 31.As previously mentioned, always the length than the parallel path the heating wire 313 in from the front end of bobbin 141 to suction cylinder 31 is long to the line length bobbin 141 front ends from storing joint Y3 on coiling face 142.Therefore, with respect to the suction streams in the suction path 311 of suction cylinder 31, joint Y3 always is positioned at the downstream of heating wire 313.
The excitation of step S8 equator clamper 27 and o 15 continues the set time.Through during given time, control computer C makes parallel clamper 27 and o 15,45 degaussings (step S9) after this excitation begins.The degaussing of parallel clamper 27 makes parallel clamper 27 be converted to clamp position, and the parallel that passes through from parallel clamper 27 is by parallel clamper 27 clampings.The degaussing of o 15 makes card shotpin 151 be fastened on the coiling face 142.O 45 degaussings make clamping wheel 42 elastic reactions in extension spring 44 press down and touch on clamping wheel 43.When clamping wheel 42 pressures were touched on clamping wheel 43, parallel Y2 just was clamped between the side face of clamping wheel 42,43.
Extend to the parallel Y2 of suction cylinder 31 via wefting insertion with nozzle 24 from parallel clamper 27, be subjected to the swabbing action of suction cylinder 31.State when Fig. 7 (a) and (b) illustrate parallel Y2 be subjected to swabbing action in suction cylinder 31.Suction cylinder 31 is formed with the suction path 311 that is curved shape, and heating wire 313 is arranged on obtuse angle bend 312 places, and therefore, shown in Fig. 7 (b), the parallel Y2 in the suction cylinder 31 contact with heating wire 313 when being subjected to swabbing action.
Carry out after the processing of step S9, control computer C sends the power supply instruction to power supply circuits 38, and making in the heating wire 313 has electric current to flow through.That is, control computer C makes hot knife 39 actions (step S10).So heating wire 313 produces very high heat, the parallel Y2 that will contact with heating wire 313 cuts off.(being positioned at the parallel of downstream one side of heating wire 313 in the suction streams in suction path 311) on the parallel Y2 that separates being cut off has joint Y3, and the parallel that joint Y3 separates with being cut off is got rid of to suction machine 34 sides.
The action of hot knife 39 continues the set time among the step S10.Through during given time, control computer C stops to send the power supply instruction to power supply circuits 38, stops to supply with electric currents to heating wire 313 after this action beginning.That is, control computer C makes hot knife 39 stop action (step S11).
Carry out after the processing of step S11, control computer C makes switching valve 33 be converted to the 1st channel status, and makes suction machine 34 stop action (step S12).
Afterwards, control computer C makes electromagnetic switch valve 29 excitations (step S13), makes electromagnetic switch valve 29 degaussings (step S14) through behind the given time.That is, make the open mode of electromagnetic switch valve 29 only keep the set time, the water of water-supply source 30 is supplied with nozzle 24 to wefting insertion via pump 26.State when Fig. 9 illustrates electromagnetic switch valve 29 by excitation.So, with nozzle 24 water spray, make the front end of the parallel Y2 that is arranged in suction cylinder 31 withdraw from and point to the wefting insertion direction from suction cylinder 31 as shown in Figure 9 from wefting insertion.
Afterwards, control computer C begins the action of loom CD-ROM drive motor M, the excitation degaussing control of o 15, the excitation degaussing control of parallel clamper 27, the action of suction machine 34, and (step S15) begins to weave cotton cloth.The rotation in junior one week of loom is not carried out wefting insertion and is dallied.Carry out at loom during the rotation in this junior one week, parallel is wound up on the coiling face 142.
The control computer C that carries out above-mentioned control is when connecting sensor 13 detects joint Y3 mobile, makes loom out of service and make bobbin 141 actions and make joint Y3 store the controlling organization on the coiling face 142 of storage Weft handling device 14.
Present embodiment can obtain following effect.
(1-1) when parallel bobbin 11 uses up, the joint Y3 of parallel Y1 and parallel Y2 moves to storage Weft handling device 14, by mobile detection of 13 pairs of these joints of connecting sensor Y3.And, when detecting joint Y3 mobile, making loom (stopping to weave cotton cloth) out of service, and make bobbin 141 carry out both quantitative counter-rotating so that joint Y3 stores on coiling face 142, joint Y3 will temporarily store on the coiling face 142 of storage Weft handling device 14.The effect that rotation produced draws in parallel in the bobbin 141 from parallel bobbin 11,12 of bobbin 141 is powerful, and the parallel that is positioned at bobbin 141 upstream sides is wound up on the coiling face 142 reliably.Promptly, make after loom CD-ROM drive motor M carries out both quantitative low speed and reverse, joint Y3 will be present on the coiling face 142 conscientiously, therefore, get rid of to the opening of warp T from coiling face 142 by storing at the parallel on the coiling face 142, just head Y3 reliably can be got rid of to shedding with joint Y3.
(1-2) in storage Weft handling device 14 with clamping wheel 42,43, when weaving cotton cloth, be wound on after line on the coiling face 142 all pulled out, to be the limit extract the parallel limit out among the clamping wheel 42,43 carries out wefting insertion.That is, spiral formula storage Weft handling device 14 is a kind of advance storage Weft handling devices of function of the constraint that not only parallel is retrained but also can make it to advance at a high speed that have, wefting insertion near the wefting insertion process that ends in, parallel was advanced at a high speed in the bound while.Using the occasion of this storage Weft handling device 14, when stopping to weave cotton cloth, joint Y3 rests on sometimes, when weaving cotton cloth final wefting insertion before stopping more next time during wefting insertion on the corresponding parallel path.That is joint Y3 rests on upstream one side of bobbin 141 sometimes when, stopping to weave cotton cloth.
And in the present embodiment, make counter the circling of loom and parallel is wound up on the coiling face 142, therefore, joint Y3 is stored reliably on coiling face 142.
(1-3) in the present embodiment, be that the parallel front end Y11 that stretches out from the jet 241 of wefting insertion with nozzle 24 is aspirated, with the parallel front end Y11 that aspirated make as introduction store joint Y3 on coiling face 142 from wefting insertion with passing the nozzle 24.Therefore, the parallel Y2 of joint Y3 back can penetrate wefting insertion automatically with in the nozzle 24, thereby does not need to carry out parallel is penetrated wefting insertion again with the operation in the nozzle 24.
(1-4) can wefting insertion becomes less bending to the parallel path design of wefting insertion till with the place ahead of the jet 241 of nozzle 24 with nozzle 24 path will be passed from coiling face 142.Therefore, as introduction parallel being sucked the processing of suction cylinder 31 with the parallel front end that stretches out with the jet 241 of nozzle 24 from wefting insertion, is effective being wound on that line on the coiling face 142 pulls out and carry out reliably that joint gets rid of.
(1-5) can be drawn into downstream one side of heating wire 313 reliably by the swabbing action of suction cylinder 31 with storing joint Y3 on coiling face 142.Therefore, for the joint Y3 that in the suction path 311 of suction cylinder 31, is positioned at the downstream of heating wire 313,, it is separated with the parallel of nozzle 24 from extending to wefting insertion by the parallel that is inhaled into being cut off with heating wire 313.That is, joint Y3 can be got rid of to shedding reliably.
