In each drive circuit 21～24, to each motor M1～M4 input speed command signal of connecting or become its based signal.More specifically, in the drive circuit 24 that the variable speed driver M4 that is connected with the 2nd feed roller F4 uses, input is from the linear velocity command signal SL of linear velocity signal generation 30 outputs, and the drive circuit of using at the variable speed driver M3 that is connected with roller drier F3 23, the drive circuit 22 that the variable speed driver M2 that is connected with sizing roller F2 uses, in the drive circuit 21 that the variable speed driver M1 that is connected with the 1st feed roller F1 uses, as the based signal that becomes speed command signal, import respectively and more leaning on the downstream and the variable speed driver M4 of adjacency than it, M3, each tach signal sg4 of M2, sg3, sg2.Drive circuit 21, drive circuit 22 and drive circuit 23 are imported stretched operation value signal SR01, stretched operation value signal SR02 and the stretched operation value signal SR03 that comes since stretch control part 40 respectively in addition.
Stretching control part 40 is connected with change-over switch SW1 in the signal T1～T3 of input from each force cell LD1～LD3.In addition, this change-over switch SW1 has when the transtension state of a control function as manual station, and this external signal T1～T3 is using when detecting tension force correction stretched operation value, and its details remains aftermentioned.
On on-line velocity signal generation 30 and the stretching control part 40, by data/address bus bs can to the twocouese mail message be connected with setting apparatus 32.The so-called touch panel of the Presentation Function of numerical value input function and demonstration numerical information or Word message etc. constitutes setting apparatus 32 by for example possessing, on setting apparatus 32, as one of operating condition, yarn speed setting value VL (several meters/minutes specifically) when yarn speed setting value VH except as the running up of two grades of yarn speeds time the (tens of specifically～hundreds of rice/minute) and low-speed running, set tension values VSL1～VSL3 for two of the driving circumferential speed ratio of the rollers at different levels that the conduct that each speed of above-mentioned each yarn speed of two grades is set respectively is adjacent, VSH1～VSH3 (specifically+number %～-number % scope) in addition, also preestablished the target warp tension value TS of each grade, the squeeze pressure of sizing roller F2, a plurality of setting values of the design temperature of roller drier F3 etc.And setting apparatus 32 has by data/address bus bs to the linear velocity signal generation 30 as suitable controller, stretching control part 40 and master controller 34 these setting values of conveying of controlling the squeeze pressure of above-mentioned sizing roller F2 or the temperature of roller drier F3 etc. by not shown actuator, and read by stretching control part 40 and data/address bus bs warp tension signal T1～T3 value function and arrange function on the picture be shown in setting apparatus, also have by data/address bus bs and from master controller 34 and not shown controller, read and show control information except that above-mentioned, the parking reason, what fault message or current warp thread batched length etc. produces the function of relevant information through axle.
In on-line velocity signal generation 30 and the stretching control part 40, input has the speed of autonomous controller 34 to select signal S2 and CRANK PULSES S3.In master controller 34 except there not being the various action buttons of diacritic, promptly repairing the low-speed running button of operating when the broken yarn specifically, continuously beyond the action buttons such as button and stop button that run up of operating when the running device of sizing machine for warp yarn 1, also input has the yarn signal from various sensors, master controller 34 can be according to the disconnection output CRANK PULSES S3 such as input of broken yarn signal or stop button operation signal, output it to linear velocity signal generation 30, or, select signal S2 corresponding to the speed of the speed of selection to linear velocity signal generation 30 and 40 outputs of stretching control part according to operation signal from the low-speed running button and the button that runs up.In addition, it at length is the signal that remains connection output when running up described later that speed is selected signal S2, CRANK PULSES S3 be when running device of sizing machine for warp yarn 1, promptly no matter run up and low-speed running and comprise between on-stream period in the time connect the signal of output, and connect the signal of exporting when also being the stopping period that comprises when stopping quetsch 1.
Therefore, when starting quetsch 1, when the operator operated the low-speed running button, master controller 34 was connected output speed selection signal S2 to linear velocity signal generation 30 and stretching control part 40, and connects output CRANK PULSES S3 to linear velocity signal generation 30.Therefore, linear velocity signal generation 30 is by the CRANK PULSES S3 under the state of connecting input speed selection signal S2, be judged as and sent the low-speed running instruction, the linear velocity command signal SL of the yarn speed setting value VL that uses corresponding to predefined low-speed running by setting apparatus 32 output, consequently variable speed driver M4 is activated and with the speed rotation corresponding to the value VL of linear velocity command signal SL.
On the other hand, as the based signal of speed command signal, imported tach signal sg4 from the speed detector TG4 that is connected with variable speed driver M4 to the drive circuit 23 that drives variable speed driver M3.Therefore, the calculator 25 of drive circuit 23 is seized back confiscated property from the tach signal sg4 of input and is obtained yarn speed value as actual linear velocity, for the linear velocity command value of obtaining, carry out except the value of each stretched operation value signal SR03 of input, also the regulation of speed reducing ratio etc. is calculated and is calculated speed value according to the rules, and rotation drives variable speed driver M3 in view of the above.Thus, adding that with the rotating speed for variable speed driver M4 the velocity rate rotation of the value of stretched operation value signal SR03 drives variable speed driver M3, in other words is the circumferential speed with respect to the 2nd feed roller F4, with the circumferential speed rotation head roll drying machine F3 of correspondence.
Equally, as the based signal that becomes speed command signal, to the tach signal sg3 of drive circuit 22 inputs that drive variable speed driver M2 from the speed detector TG3 that is connected with variable speed driver M3.Therefore, the calculator 25 of drive circuit 22 is seized back confiscated property from the tach signal sg3 of input and is obtained yarn speed value as actual linear velocity, for the linear velocity command value of obtaining, carry out except the value of each stretched operation value signal SR02 of input, also according to the rules the regulation of speed reducing ratio etc. is calculated and is calculated speed value, and rotation drives variable speed driver M2 in view of the above.Thus, adding that with the rotating speed for variable speed driver M3 the velocity rate rotation of the value of stretched operation value signal SR02 drives variable speed driver M2, in other words is the circumferential speed with respect to roller drier F3, with the circumferential speed rotation driving sizing roller F2 of correspondence.
Equally, to the drive circuit 21 that drives variable speed driver M1, as the based signal that becomes speed command signal, input is from the tach signal sg2 of the speed detector TG2 that is connected with variable speed driver M2.Therefore, the calculator 25 of drive circuit 21 is seized back confiscated property from the tach signal sg2 of input and is obtained yarn speed value as actual linear velocity, for the linear velocity command value of obtaining, the regulation of carrying out except the value of stretched operation value signal SR01 of input, also considering the speed reducing ratio etc. of not shown mechanical reduction gear etc. is calculated and is calculated speed command, and rotation drives variable speed driver M1 in view of the above.Thus, adding that with the rotating speed for variable speed driver M2 the velocity rate of the value of stretched operation value signal SR01 drives variable speed driver M1, in other words is the circumferential speed with respect to sizing roller F2, rotates the 1st feed roller F1 with the circumferential speed of correspondence.
Like this, when low-speed running, can make the 2nd feed roller F4 rotation with the circumferential speed of yarn speed setting value VL to be equivalent to low-speed running, and similarly with corresponding to the circumferential speed (velocity rate) of each stretched operation value signal SR03, SR02 and SR01 in addition roller of driven at low speed, i.e. driven at low speed roller drier F3, sizing roller F2 and the 1st feed roller F1 respectively respectively.
Below, with reference to inside calcspar shown in Figure 2, specify the stretching control part 40 of this each stretched operation value signal SR01, SR02 of output and SR03.Stretching control part 40 has substantially: to interval at different levels as the control that stretches export respectively stretched operation value signal SR03, SR02 and SR01 the 1st stretching control part the 42, the 2nd stretching control part 44 and the 3rd stretching control part 46, be connected as with the data/address bus bs of the order wire of setting apparatus 32 on signal converter 48.In addition, on the 1st stretching control part 42～the 3rd stretching control part 46, have respectively as corresponding to two stretching control parts of selecteed two yarn speeds, low-speed tensile operating portion 50 and high-speed stretch operating portion 52, and select their converter 58.As an example, use the 3rd stretching control part 46 inner calcspars of the example in detail output of Fig. 2 as the stretched operation value signal SR03 of the tension values between roller drier F3～the 2nd feed roller F4.Other stretching control part 42,44 is diagram not, but identical with the 3rd stretching control part 46 structures.
Low-speed tensile operating portion 50 and high-speed stretch operating portion 52 have correction calculator 53, adder 54 and converter 56 respectively.Low-speed tensile operating portion 50 about the 3rd stretching control part 46, in more detail, to a side's of correction calculator 53 the input terminal input tension signal T3 from force cell LD3, to the opposing party's input terminal, input is from the target warp tension signal TS3 of signal converter 48.Correction calculator 53 is according to the deviation delta T of two input signals, the deviation delta T of the average warp tension of obtaining according to per cycle stipulated time or every regulation yarn length of travel carries out that PID calculates wait and backward a side's of the adder 54 of one-level input terminal export correction amount SL.In addition, the setting tension values signal SRL31 that uses during from the low-speed running of signal converter 48 is transfused to the other input terminal of adder 54, and by input back one-level converter 56 1 sides' input terminal along separate routes.And adder 54 be will input two signal plus and output corresponding to the device of the signal of addition result, setting tension values VSL3 that specifically low-speed running is used and the addition result of above-mentioned correction amount SL (being the value of VSL3+ Δ SL) are input to the opposing party's of converter 56 input terminal as signal SRL32.And to the switching signal S1 of converter 56 input, to side's input terminal input of converter 58 output signal SRL33 from converter 58 from change-over switch SW1.
High-speed stretch operating portion 52 its structures and above-mentioned low-speed tensile operating portion 50 are roughly the same, and the setting tension values signal that inputs to adder 54 in the high-speed stretch operating portion 52 and converter 56 is running up with setting difference on this aspect of tension values signal SRH31 from signal converter 48 outputs.Also inequality on the opposing party's input terminal this point that is transfused to as signal SRH33 to converter 58 from the output signal of the converter 56 of high-speed stretch operating portion 52 in addition.
On the converter of having imported from the output signal SRL33 of the output signal SRH33 of high-speed stretch operating portion 52 and low-speed tensile operating portion 50 58, as switching signal more along separate routes input come the speed of autonomous controller 34 to select signal S2, and its output is transfused to calculator 25 to drive circuit 23 as stretched operation value signal SR03.
In addition, signal converter 48 has: understand the data signal that transports by data/address bus bs from setting apparatus 32, be converted to corresponding to the analog signal of understanding the result and the function of supplying with to the internal circuit of stretching control part 40, and according to being the data signal and the function of carrying with the analog signal conversion of input to data/address bus bs from the requirement of setting apparatus 32, as and setting apparatus 32 between the function of so-called COM1.In more detail, signal converter 48 is exported the analog signal corresponding to the value of carrying from setting apparatus 32 respectively, promptly sets tension values signal SRH31 corresponding to goal tension signal TS3, the low-speed running of target warp tension value TS3 with setting tension values signal SRL31 and running up to use.In addition, the tension signal T3 that signal converter 48 is accepted as the analog signal input according to the requirement of setting apparatus 32 1 sides, can carry actual warp tension value to setting apparatus 32 by data/address bus bs.
Secondly, be to be set under the state of the suitableeest state, the situation at default operating condition for running continuously, change-over switch SW1 is switched to and connects side and connect output signal S1.Therefore input signal from adder 54 is selected and exported to the converter 56 of importing this signal from two input signals.Therefore, as mentioned above, operate the operator under the low-speed running state of low-speed running button, adder 54 is exported in the running beginning originally corresponding to the value of low-speed running with setting tension values VSL3.But, in running subsequently, actual warp tension value T3 produces deviation delta T with respect to goal tension value TS3, the PID that correction calculator 53 is stipulated calculates and waits and input correction amount SL, adder 54 outputs are delivered to the converter 58 of next stage again corresponding to the signal SRL32 in the value of setting the correction tension values (being VSL3+ Δ SL) that adds correction amount SL on the tension values VSL3 and revise through converter 56 thus.In addition, the correction amount SL of correction calculator 53 outputs is the values of calculating of the correction on the direction of eliminating variation in warp tension, for example when warp tension T3 is bigger than goal tension value TS3, export the correction amount SL that reduces in negative direction, on the contrary when than goal tension value TS3 hour, the correction amount SL that output increases in positive direction.
On the other hand, because converter 58 import the speed of coming autonomous controller 34 and is selected signal S2 under off-state, converter 58 from as select signal SRL33, the SRH33 of input signal from the signal of low-speed tensile operating portion 50 and as stretched operation value signal SR03 backward the drive circuit 23 of one-level export.
At this moment, stretching control part 40 is transformed under the state of connecting a side at change-over switch SW1 as mentioned above, the control model of setting tension values according to detected warp tension correction is effective, owing to be in the low-speed running state, the signal SRL33 of converter 58 1 sides is effective, so the setting tension values VSL3 that output is used for low-speed running is eliminating the stretched operation value signal SR03 that revises on the tension force bias direction, and carry out based on the driving that is accompanied by the tension values that detects tension force and revise for the setting tension values, wherein the tension force deviation is based on the tension force deviation with the detected warp tension T3 of jockey pulley R3.So, because drive circuit 23 is with based on driving variable speed driver M3 and roller drier F3 for linear velocity signal SL, the velocity rate of eliminating the value of the stretched operation value signal SR03 that revises on above-mentioned deviation ground, so even warp tension T3 changes, also can realize of the stretching control roller drier F3～2nd feed roller F4 between of warp tension value T3 long term maintenance by the correction of above-mentioned stretched operation value in goal tension value TS3.
The operator is by the operation button that runs up then, and master controller 34 is connected output speeds and selected signal S2.Thereby, linear velocity signal generation 30 is under the state of connecting input speed selection signal S2 and by input CRANK PULSES S3, be judged as and send the instruction that runs up, to quickening and finally export linear velocity command signal SL at leisure with yarn speed setting value VH corresponding to setting value VH by predefined the running up of setting apparatus 32.Therefore variable speed driver M4 is to quickening corresponding to the speed of yarn speed setting value VH, finally with the high speed rotation corresponding to setting value VH.
On the other hand, come the speed of autonomous controller 34 to select signal S2 to be converted into on-state, export thereby converter 58 converts to from the signal of high-speed stretch operating portion 52 and as stretched operation value signal SR03.As above narrate in addition, because signal S1 is in the connection output state, so the setting apparatus 56 of high-speed stretch operating portion 52 is selected signal that is transfused to and output from adder 54 from two input signals.High-speed stretch operating portion 52 is used the value of setting tension values VSH3 in the output of running beginning initial stage corresponding to running up.But, when deviation delta T takes place with respect to goal tension value TS3 in actual warp tension value T3 in running subsequently, the PID that correction calculator 53 is stipulated calculates and output correction amount SH, thereby adder 54 outputs are exported to the converter 58 of next stage through converter 56 corresponding to the signal SRH32 in the value of setting the correction tension values (being VSH3+ Δ SH) that adds correction amount SH on the tension values VSH3 and revise again.In addition, the correction amount SH of correction calculator 53 outputs is also the same with above-mentioned correction amount SL, it is the calculated value of the correction on the direction of eliminating variation in warp tension, for example when warp tension value T3 is bigger than goal tension value TS3, the correction amount SH that output reduces in negative direction, on the contrary when than goal tension value TS3 hour, the correction amount SH that output increases in positive direction.
Converter 58 selects signal S2 to be transformed into on-state by the speed of coming autonomous controller 34, selects from the signal SRH33 of high-speed stretch operating portion 52 and as stretched operation value signal SR03 drive circuit 23 outputs of one-level backward.At this moment, 40 outputs of stretching control part are being eliminated the stretched operation value signal SR03 that revises on the tension force bias direction for the setting tension values VSL3 of the usefulness that runs up, and wherein the tension force deviation is based on the tension force deviation with the detected warp tension T3 of jockey pulley R3.
On the other hand, above-mentioned variable speed driver M4 quickens to the speed that sets value VH corresponding to yarn speed, and on the drive circuit 23 of the tach signal sg4 that accepts such variable speed driver M4 that quickens, imports above-mentioned stretched operation value signal SR03 again.Therefore, drive circuit 23 based on the speed value that adds the stretched operation value for the speed command that increases with lasting, order is quickened variable speed driver M3, finally with the high speed rotation of the speed value of the stretched operation value signal SR03 of value add to(for) yarn speed setting value VH.And, in this running up when variation in warp tension takes place when, by eliminating the stretched operation value that the tension force deviation is exported, change the actuating speed of variable speed driver M3, consequently, for the setting tension values VSH3 of the usefulness that runs up, carry out the stretched control of revising the stretched operation value, so that detected warp tension value T3 always is maintained in goal tension value TS3.Thus, can run up always stably keeping under the situation of the warp tension between roller drier F3 to the 2 feed roller F4.
In addition, in this embodiment, the stretching control that is based on detected warp tension value T3 between roller drier F3 to the 2 feed roller F4 that describes in detail, but in other intervals of implementing to stretch control, be between sizing roller F2～roller drier F3 or the control of the stretching between the 1st feed roller F1～sizing roller F2 also identical.
By running up of this device of sizing machine for warp yarn 1, the constipation bundle should be through the batch process of axle soon.Then, the production new varieties when axle, set the operating condition of temperature etc. of squeeze pressure, yarn gait of march and the roller drier of above-mentioned setting tension values, sizing roller corresponding to the batch of this production, adjust the degree of drying of running and affirmation warp tension state and yarn then, and adjust operating condition once more.On this basis, device of sizing machine for warp yarn is turned round continuously.The a series of processing sequences of this production new varieties when axle describe with reference to Fig. 3.
Setting in the process of new operating condition according to the guiding book of making according to experience in the past etc., the operator at first sets each tension values as setting tension values input setting apparatus 32, and the change-over switch SW1 that will be used for transtension control is transformed into and disconnects side (ST001).The operator operates the low-speed running button as the running button then, makes device of sizing machine for warp yarn 1 low-speed running (ST002).
At this moment turn back to Fig. 2,, set tension values signal SRL31 as output signal, backward converter 58 outputs of one-level so converter 56 converts to because converter 56 has been imported the signal S1 that disconnects output.Consequently exported corresponding to predefined low-speed running with the stretched operation signal SR03 that sets tension values VSL3, with based on for the circumferential speed of the setting tension values of the yarn speed of selecting than driving variable speed driver M3.In addition, about this point, other variable speed drivers M1～M2 that controls for stretching too.
At this moment, according under the low-speed running situation by each shown warp tension value T1～T3 of the situation that is shown in the warp tension value on the setting apparatus, the operator is to every grade of the control that stretches, judge warp tension state (warp tension value) whether suitable (ST003), when the operator is judged as judged result and is " NO ", by setting apparatus 32, except as and the squeeze pressure of the sizing roller of the strong operating condition of warp tension relevance, the yarn gait of march, beyond the temperature of roller drier, also adjust (ST004) to setting tension values and setting value in addition thereof, return the step (ST003) of the judgment processing of judging warp tension once more, continue to adjust.In addition, because setting apparatus 32 is read each warp tension value by data/address bus bs from signal converter 48, and on same picture, showing side by side, so a series of adjustment operations such as the affirmation of the change that the operator can successfully set value, warp tension value with the setting value of each operating condition.
When being in suitable situation by such adjustment warp tension value, when promptly operator's judged result is " YES " in judgment processing steps ST003, enter next procedure, judge whether to finish to adjust running (ST005).Because the adjustment that run up this moment does not finish, so the operator judges " NO ", return treatment step ST002, press the button that runs up specifically, judge that from the tension force that so far carries out (ST003) carries out the adjustment (ST004) of operating condition repeatedly and finally return treatment step ST005 at the low-speed running state.A series of like this adjustment, judge to finish, final treatment step ST005 be judged as " YES " time, enter next procedure.And the operator sets subsequently continuous running institute indispensability respectively, be shown in the goal tension value TS1～TS3 (ST006) of each the warp tension value T1～T3 conduct of reality in the display frame of setting apparatus 32.Then, the operator is transformed into change-over switch SW and connects a side (ST007), makes device of sizing machine for warp yarn 1 begin running continuously with remaining unchanged, finishes the handling process of a series of adjustment.
When before so continuous running begins, adjusting running, by at first carrying out above-mentioned set-up procedure, do not follow the correction that detects tension force at the stretching control part, carry out the 2nd function and adjust running, so the operator needn't be as in the past based on the correction of the setting tension values of tension force wait by the time warp tension stable till, can easily obtain the relation of the actual warp tension of the operating condition set and demonstration.Even suppose the operating condition big to the warp tension influence degree, also can the limit seeing that the shown warp tension value limit of setting apparatus easily adjusts these operating conditions, with the warp tension that obtains to wish, so can be than shortened the needed time of running of adjusting significantly in the past.And, can with based on the adjustment of the operating condition in the previous steps the value of obtainable actual warp tension be set at subsequently used goal tension value when the running continuously.Then, by selecting above-mentioned the 1st function of execution and begin continuous running, can after turning round continuously, also warp tension stably be maintained in the goal tension value, so can produce colory effectively through axle at the stretching control part.
Among the treatment step ST006 formerly, with manual input target warp tension value TS1～TS3, but also can be by carrying out the operation of this purpose, thereby automatically set each value based on the warp tension value T1～T3 of actual measurement (for example the mean value of warp tension etc.) at setting apparatus 32.
About the above embodiments, can carry out following distortion.About employed target warp tension value TS1～TS3 when carrying out the 2nd function, in circuit shown in Figure 2, can constitute at low-speed running and all use the structure of identical value, but also can be the structure of setting mutually different warp tension with running up.
In the device of Fig. 1, can utilize the tach signal of variable speed driver M4 to drive variable speed driver M3, similarly also can utilize the tach signal of variable speed driver M3, M2 to drive variable speed driver M2, M1 respectively,, drive the opposing party's roller of the control that is stretched with respect to a side roller.About the speed command of such variable speed driver, also can replace tach signal, and based on the speed value that has added from the linear velocity command signal SL of linear velocity signal generation 30 and stretched operation value signal at different levels, control stretches based on reality.(for example, with reference to the flat 2-80658 of Japan's publication number the 1st figure.)
About setting tension values by each setting of two yarn speeds, also can set different values because of the difference of yarn speed, also can set identical value.In addition, when low-speed running, it is longer to batch the time required till on the axle, and the warp thread of having gone up slurry is trapped in the drying section that is used to be dried for a long time and strengthened amount of contraction, also high when consequently the warp tension ratio runs up.About this warp thread shrinkage degree, also because of the difference of yarn kind is different, but compare the tendency that increasing is arranged when running up, so in fact, the setting tension values during low-speed running is set to value also little when running up mostly.
In addition in the above embodiments, about in running continuously, based on detected warp tension to setting the corrective action of tension values, can run up and the both sides of low-speed running carry out, also can be applicable to the form of only carrying out a side.
About the yarn speed of device of sizing machine for warp yarn 1, low-speed running is arranged, run up these two kinds, but also can be to have third gear or above yarn speed, under this occasion, when each yarn speed is set tension values, also can be suitable for the present invention.
In the example of Fig. 1～shown in Figure 2, the linear velocity signal generation 30 and the stretching control part 40 of pulling control 10 have been realized constituting with a plurality of circuit, but also can constitute, also can realize with a controller of each function of intensive master controller 34 or not shown controller with circuit.About sort controller, be not limited to the processing of only using hardware, can also handle by microcomputer and software and realize.
About the structure of device of sizing machine for warp yarn 1, above-mentioned Fig. 1 (Fig. 4) is the device of sizing machine for warp yarn that mainly uses staple fibre, but also is applicable to the device of sizing machine for warp yarn of corresponding filament yarn certainly.Under the situation of filament yarn corresponding intrument, compare with the short fibre yarn corresponding intrument, consider for example between sizing roller F2 and roller drier F3, newly to establish hot-air drying device etc. and appended this structure of change etc., but also can consider by changing the configuration of active type driven roller and roller drier, maybe will change to above-mentioned the 2nd feed roller F4 roller in addition by the roller that the yarn speed setting value drives (for example, owing to constitute the structure of omitting the 2nd feed roller, change to roller drier F3), the form of the internal structure of change pulling control 10.But the same with the above embodiments (invention), so long as in batching running, can revise the control of tension values, just can be applicable to any device based on detected warp tension between two rollers.
