Be divided into two kinds between the on-stream period after the startup of loom 10: the one, begin this section till detected warp tension value stabilization is when being same numerical value with normal operation goal tension value from startup during, promptly the what is called during this section till the deviation of calculating is eliminated starts during the change, the one, start during the normal operation later during changing, the warp tension value stabilization that promptly is detected is on normal operation goal tension value, and during the normal operation eliminated of deviation.
The 1st embodiment
When the rotational angle of main shaft 44, for example during 10 ° of revolutions, warp tension control part 58 will be remembered detected warp tension value T (tension force detection step) in the memory 54.
Arithmetic unit 50 is according to the warp tension value T of input, and is every through Tu during the detection unit, will calculate the typical value (typical value calculation step) of warp tension value T.In the present embodiment, with typical value as average warp tension value.
Tu comprises during the cycle period Ts during detecting unit.In other words, detect Tu during the unit with cycle period Ts be unit, by 1 above cycle period Ts form during.In the present embodiment, Tu is same as cycle period Ts during the detection unit.
Cycle period Ts for example is that rotational angle from main shaft is 50 ° 360 ° altogether to changeing angle behind 1 circle when being 50 °.But the elementary period of cycle period Ts and amortization period are same rotational angle θ, cycle period corresponding to main shaft just change during 1 circle can, for example from 0 ° to change behind 1 circle 0 ° have 360 ° altogether just.
Memory 54 be responsible for memory after loom starts to comprise detect Tu during the unit during the end of a period moment till supervision during the average warp tension value (typical value memory step) of Tm.Tm during the supervision, for example after loom 10 starts to the 10th throw a spear a little be till 10 cycle period Ts during.
Like this, Tm was made of continuous a plurality of cycle periods during the supervision, and also can be during monitoring being provided with cycle period Ts between the side's of Tm cycle period Ts and the opposing party's the cycle period Ts is the tempus intercalare more than 1 of unit.
When producing thick and thin places after loom 10 starts, the operator presses the button of stipulating on the picture of display 56.Thus, the average warp tension value of Tm during the supervision that memory 54 is remembered is presented at (typical value step display) on the display 56 by display controller 55, and therefore, the operator just can hold the variation of the average warp tension value of Tm during the inspection easily.
At this, because Tm is equivalent to begin Tu during the detection unit till several the 10th during monitoring after loom 10 starts, so display 56 demonstrations is average warp tension value till from the 1st to the 10th.
The operator according to changing from 10 average warp tension values of the 1st average warp tension value to the and these time serieses, infers the generation reason of thick and thin places, and carries out the adjustment of loom.
Specifically, when the 1st average warp tension value bigger differentiated the time than normal operation target warp tension value, set, so that tension force is replied the loom 10 startups level before of moving, perhaps, the ride gain of control output motor 32 is turned down for the rapid variation of the velocity of rotation that reduces the output shaft that suppresses to export motor 32 by the warp tension after starting.
Like this, because thick and thin places is easy to generate after starting, the operator changes by the time series of observing the average warp tension value after starting, and just can easily infer the reason that thick and thin places produces.
And, showing that by display 56 1 average warp tension value during the detection unit is a typical value, the operator just can hold the warp tension value in this moment, thereby carries out the adjustment of loom easily.
The variation 1 of the 1st embodiment
Tu and cycle period Ts are used as same the explanation during the detection unit, and can certainly be set as Tu during the detection unit is the integral multiple of cycle period Ts.For example, detect Tu during the unit can be by a plurality of circulations constitute make the pattern of knitting during.
Memory 54 is responsible for memory warp let-off speed and the two corresponding typical value of coiling speed when the rotational angle θ of main shaft 44 passes through the angle (for example 0 °) of regulation, and the two corresponding typical value of warp let-off speed and coiling speed also may be displayed on the display 56.And at this moment, memory 54 can not show typical value, only shows in warp let-off speed or the coiling speed any one on display 56.
The variation 2 of the 1st embodiment
The average warp tension value that Tm during monitoring can be calculated shows the coordinate figure as transverse axis during monitoring as the longitudinal axis in display 56.Perhaps, can poor variation between variation that shows each average warp tension value of representing with the coordinate table on the display 56 and normal operation target warp tension value.
Like this, the operator just can hold the variation of average warp tension value by visual observation.
The variation 3 of the 1st embodiment
Among the embodiment 1, the mean value that detects the warp tension value of Tu during the unit is shown that in display 56 just the minimum of a value at least of the warp tension value T of Tu or maximum show during the unit of detection in display 56.
Fig. 3 is a coordinate of using curve L1 to show in display 56 the time series variation of warp tension value T.
Stain C1 and C2 detect during unit maximum and the minimum of a value of Tu and represent as the typical value relevant with the tension force of warp thread 12 each.But, in display 56, can only show the stain of maximum or minimum of a value.
Fig. 4 is a coordinate of 2 continuous cycle period Ts being used as the warp tension value T when detecting Tu during the unit.In the illustrated example, each is detected the maximum of Tu during unit and minimum of a value as the typical value relevant with the tension force of warp thread 12, and represent with stain C1 and C2.Maximum and the minimum of a value of each cycle period Ts beyond stain C1 and the C2 then do not show.
Fig. 5 be 2 continuous cycle period Ts are used as peaked mean value when detecting Tu during the unit, each cycle period Ts and each cycle period Ts the mean value of minimum of a value as the typical value relevant with the tension force of warp thread, and the coordinate of demonstration on display 56.
Fig. 6 be monitor during in the Tm, during the unit of detection and then, in 1 cycle period Ts after the Tu, that do not detect warp tension, maximum and minimum of a value are used as the typical value relevant with warp tension, and with its coordinate that on display 56, shows.
Fig. 7 be with each mean value that detects the maximum of Tu during unit and minimum of a value as the typical value relevant with the tension force of warp thread, and the coordinate of demonstration on display 56.And in variation 3, what expression controller 55 showed on display 56 can not be coordinate but the pairing typical value of each stain.
The variation 4 of the 1st embodiment
The foregoing description shows is the mean value that detects the warp tension value T of Tu during the unit, the warp tension value T in the time of also can showing the rotational angle θ of main shaft 44.For example, can be with 1 cycle period Ts as detecting Tu during the unit, and expression detects the warp tension value T of the rotational angle θ of the regulation of Tu during the unit.And, can also be with a plurality of cycle period Ts as detecting Tu during the unit, and the warp tension value T of expression when detecting the rotational angle θ of the regulation of Tu during the unit.
During the supervision Tm by a plurality of detection units during Tu form the mean value of the warp tension value T when typical value can be shown as the rotational angle θ of regulation on display 54.At this moment, the rotational angle θ of this regulation preferably avoids harness motion or the rotational angle of the main shaft that the influence of beating up occurs easily as warp tension value T.
The 2nd embodiment
The warp let-off control model of the warp thread of the foregoing description often is taken as same describing in the running of loom, yet present embodiment will be showed the example of warp let-off control model change in the loom running.Promptly, after starting for example according to arbitrary speed control, when suppressing the order change warp let-off control model of control, control usually, describe about the example of remembering front and back when warp let-off control model separately changes to other warp let-off control model about the resume of the typical value of warp thread.
Arbitrary speed control is arranged in the present embodiment, suppress control and control this 3 kinds of warp let-off control models usually.
So-called arbitrary speed control is the such control of output shaft rotation that irrelevantly makes the output motor with the variation of the warp tension value that is detected.The velocity mode of the warp let-off speed of warp thread is set in setting apparatus 52.
Specifically, by setting apparatus 52 setting speed patterns (the warp thread warp let-off speed of regulation and specified time limit, for example number of pick), and according to the velocity mode that configures, loom control device control output motor.
The so-called inhibition controlled, and is the ride gain in controlling is usually diminished the such control of change of the velocity of rotation of the output shaft of inhibition output motor.
Specifically, arithmetic unit 50 configures the ride gains when suppressing control in advance on setting apparatus 52, and after loom started, arithmetic unit 50 can calculate the average warp tension value of Tu during the unit of detection respectively.Ride gain when the ride gain ratio when suppressing control is controlled usually is little.
And arithmetic unit 50 can be calculated average warp tension value that computing obtains and the deviation between the normal operation target warp tension value.Arithmetic unit 50 according to make calculate deviation eliminate inhibition control the time ride gain calculate correction.Warp tension controller 58 according to calculate the rotation of output shaft of correction control output motor 32.
Thus, because the ride gain of the ride gain when suppressing control during than common control is little, so correction of calculating, under same warp tension value, obtain when suppressing control than common control the time obtain little, the change of the velocity of rotation of the output shaft of output motor 32 be inhibited more during also than common control (inhibition calculation step).
More particularly, the numerical value of the average warp tension value of on setting apparatus 52, being remembered before and after the pre-set warp let-off control model change.In other words, the number of Tu during the detection unit during setting monitors on setting apparatus 52 in advance in the Tm.
For example, Tm is before and after the change of warp let-off control model during the supervision, and the number of Tu is 2 during the detection unit.That is, Tm is 4 and detects Tu during the units during the supervision.And Tu is 1 cycle period Ts during the detection unit.
CRANK PULSES S1 one is input to the loom control device, after loom 10 begins to start, in the time of loom 10 beginning arbitrary speed controls, warp tension control part 58 calculates the average warp tension value (typical value calculation step) of each warp tension value T that throws a spear.The warp tension mean value that calculates is remembered (typical value memory step) in the memory 54 at any time.
Loom is at first made with arbitrary speed control and is knitted.Arbitrary speed control is made according to predefined velocity mode and is knitted.
Loom is after arbitrary speed ends, then to suppress to control to make knitting (warp thread Status Change step).When suppressing to be controlled at warp tension and reaching stable state, stop after promptly satisfying predefined end condition.End condition is, for example at any time the memory average warp tension value and the difference between the normal operation target warp tension value enter regulation scope in the time, perhaps during the continuous detection unit of regulation in the Tu, the difference between average warp tension value and the normal operation target warp tension value just stops when entering in the scope of regulation.Or in during regulation, the situation that above-mentioned end condition has satisfied the number of times of regulation also is same.
Then, the loom control device changes to warp let-off control model to make after the common control and knits (warp thread Status Change step) from suppressing control.
When producing thick and thin places when changing warp let-off control model as described above, the typical value of Tm during comprising during arbitrary speed control is altered to supervision when suppressing control Tm or comprising supervision when suppressing control and be altered to common control, promptly warp thread mean tension value is shown to the operator in display 56.The operator just can hold the warp thread mean tension value of Tm during the shown supervision thus easily.
Specific again, will show on the display controller 55 from arbitrary speed control to be altered to any inhibition change button and show that inhibition when suppressing control and be altered to common control changes constantly any button labels usually on display 56 constantly when suppressing control.The operator can select by any inhibition change moment button or suppress the button constantly of change usually.
Display controller 55 reads the average warp tension value of Tm during the pairing supervision of selecteed button from memory 54, the average warp tension value that reads is presented at (typical value step display) on the display 56.
Thick and thin places is easy to generate the front and back in the change of warp let-off control model.So no matter whether thick and thin places produces, the operator just can suitably revise the setting value of each warp let-off control model, and the operator can also infer the reason of thick and thin places generation by observing the variation of above-mentioned average warp tension value after before changing.
And, display controller 55 can be by utilizing the warp let-off control of let-off motion, but by utilizing the control of batching of batching apparatus, the average warp tension value of control model after before changing is presented on the display 56.At this moment, with use the warp tension sensor different with the warp tension sensor to the warp tension value also can apply in the calculating of average warp tension value.
The variation 1 of the 2nd embodiment
Be to carry out the change of warp let-off control model among the embodiment 2, yet also can dispense the warp let-off control model of arbitrary speed control or inhibition control according to the order of arbitrary speed control, inhibition control, control usually.
Specifically, the control model of carrying out after the startup can be common control, also can be to suppress control and control usually, arbitrary speed control and control usually.
In order to suppress the generation of thick and thin places, generally can reach usually the warp let-off control that the order of the control model of control is carried out warp thread according to suppressing control.But, even carried out such control, still produce thick and thin places, just also carry out the warp let-off control of warp thread according to the order of arbitrary speed control, inhibition control, the common control model of controlling.
The variation 2 of the 2nd embodiment
Among the embodiment 2, the warp let-off control according to the warp tension value has been described.But embodiment 2 can also distortion as following.For example, the normal speed of warp thread, can only advance batching apparatus is arbitrary speed control.
And, batch motor and output motor, for according to the enterprise schema's change weft count that configures in advance, can carry out the control (weft count control) of these base speed changes.
In the loom running,, change the loom rotation numerical control system of desired value of the normal rotation number of main shaft according to making the i.e. variation of the enterprise schema etc. of the fabric of knitting of making of the condition of knitting.When carrying out these controls, can show on the display that the speed that comprises above-mentioned warp thread is the normal speed average warp tension value of Tm during the supervision of back before changing.
The variation 3 of the 2nd embodiment
In the time of will changing textiles energetically and organize, can on setting apparatus, set for example opening pattern of warp thread of specific enterprise schema, calculate each average warp tension value then corresponding to the warp tension value of Tu during a plurality of detection units of the enterprise schema that sets.
For example, in advance by setting apparatus 52, make the respectively pairing enterprise schema of Tu " AAABB " during the unit of detection of memory 54 prior memories, and, the average warp tension value T of the enterprise schema of 54 of memories memory B, only so just can on display, show enterprise schema " BB " promptly the the the 4th, the 5th, the 9th, the 10th ... detection unit during the average warp tension value of Tu.
The 3rd embodiment
Fig. 8 is with the resume of the average warp tension value example in the screen displayed of display 56.In the illustrated example, be will from memory 54, be remembered inhibition control (insensitiveness control) be altered to the average warp tension value of Tu during the respectively unit of detection of front and back of common control, show in display 56 as the resume of typical value.
Specifically, the left-half of Fig. 8 in suppressing control, is showing respectively during the unit of detection detected average warp tension value among the Tu.In the illustrated example, shown warp let-off control model after before changing, the pairing average warp tension value of Tu during continuous 10 the detection unit separately.
Equally, at the right half part of picture, in common control, showing the pairing average warp tension value of Tu during 10 the continuous detection unit after warp let-off control model before changing.
Like this, the operator just can hold the variation that is altered to the pairing average warp tension value of Tu during the detection unit of " control usually " such warp let-off control model after before changing from " insensitiveness control " (suppress control), therefore, the operator just can judge that whether reason that thick and thin places produces is because the variation of warp tension, and perhaps whether the setting value of each control model is suitable.
And, because the operation operator can hold the reduction amount with respect to the average warp tension value of normal operation target warp tension value, so just can judge the reduction of the ride gain of output motor.
In the illustrated example, be the state of having selected " usually " button on top, the operator is by pressing " normal speed " button, and the resume of the average warp tension value after the control of beginning arbitrary speed just are revealed; By pressing " insensitiveness " button, the resume that are altered to the average warp tension value of insensitiveness control front and back from arbitrary speed control just are revealed.
The 4th embodiment
The warp thread control device of present embodiment, in the normal operation of loom 10, according to detected warp tension value and normal operation target warp tension value, control the warp thread let-off motion, make the warp tension value near normal operation target warp tension value (warp tension control step).The warp thread control device detects the stable state (steady state detection step) that the difference that shows between warp tension value and the normal operation target warp tension value enters prescribed limit.
Fig. 9 is after the loom of demonstration on display 56 starts, and the warp let-off control model of warp thread is in the velocity of rotation variation of the variation of the average warp tension value under the common control, output motor, the weft count variation of fabric (step display during the startup change).
Certainly, the variation of Fig. 9 that shows below (a) and Fig. 9 (b) can show with numerical value, also can be with the coordinate demonstration as each figure.
In the illustrated example, after loom started, the output shaft that batches motor often was controlled as coiling speed and keeps certain.The rotation control of the output shaft of output motor is that so-called PID controls and carries out (warp tension control step) according to warp tension.Thus, the output shaft of output motor is controlled for the deviation between the average warp tension value of eliminating normal operation target warp tension value and detection.
Fig. 9 (a) is the coordinate that shows the average warp tension value variation the when ride gain will export motor becomes a big value.In the illustrated example, the ride gain of output motor is 50.
With reference to diagram, normal operation target warp tension value is set to 200kg.And average warp tension value is after loom starts beginning, and is lower than normal operation target warp tension value.During the startup change after starting beginning from loom till the moment of regulation, after loom started, average warp tension value increased at once, and once above normal operation target warp tension value.In the present embodiment, starting during the change is 10 to throw a spear a little, i.e. 10 cycle period Ts.
After this, average warp tension value reduces, and beginning is to passing near normal operation target warp tension value.Afterwards, average warp tension value just is stabilized in normal operation target warp tension value, and the operating condition of loom also becomes normal condition.
This shows the coordinate that the velocity of rotation of output motor changes with reference to Fig. 9 (b), after loom starts, before deviation calculation is come out, once is being increased to normal rotation speed.
Deviation for example is to detect Tu calculates during the unit typical value and the back to back the 2nd from the 1st to detect between the typical value that Tu calculates during the unit and calculate, but, because after loom starts, the 1st detects during the unit before the Tu not Tu during the unit of detection, so can't calculate the typical value that Tu obtains during the detection unit before.
Loom control device 40, one obtains from the 2nd detecting the typical value that Tu calculates during the unit, by big gain, the velocity of rotation of the output shaft of output motor can significantly reduce, in order to eliminate deviation, velocity of rotation rises gradually afterwards, and the excessive evaluation of deviation also can be eliminated like this.And, warp tension control part 58, when the deviation that calculates entered in the scope of predefined permissible value, judgement was that normal condition is that warp tension reaches stable state (steady state detection step).In other words, during in a single day average warp tension value moves on to and the target warp tension value that runs well is approximately approaching value, the velocity of rotation of the output shaft of output motor reaches normal rotation speed, and settles out.
Specifically, after loom starts, batch motor and rotate according to normal rotation speed, slower than the velocity of rotation of batching motor by the velocity of rotation that makes the output motor, warp thread is just pullled like this, and warp tension value and even average warp tension value can increase.And when average warp tension value is passed and normal operation target warp tension value is roughly the same value, the velocity of rotation of output motor can be passed to normal speed.
On the other hand, when average warp tension value was bigger than normal operation target warp tension value, by the velocity of rotation that the fast mistake of velocity of rotation that makes the output motor is batched motor, warp thread was just at the output motor with batch and obtain mitigation between the motor.Its result is exactly to reduce warp tension value and even average warp tension value.
Shown in Fig. 9 (b), after ride gain arrived to a certain degree greatly, the amplitude that the velocity of rotation of the output motor 32 during startup changes just became greatly, and the velocity of rotation of the output shaft of output motor 32 accelerates slack-off at short notice.Like this, warp thread just can not constant speed ground output, the big ride gain of therefore exporting motor 32 becomes the reason that thick and thin places such as thick section and light filling bar produce.
With reference to Fig. 9 (c), the weft count that therefrom can read as follows changes: if the weft count of the fabric during normal condition is 50 pieces/cun, after loom starts so, weft count just rises, weft count reaches 55 pieces/cun when the peak, after this, weft count reduces gradually, in the time of till average warp tension value stabilization arrives normal operation target warp tension value, weft count is got back to normal weft count.
Like this, when weft count is bigger than normal weft count, just occur thick section in the fabric.On the other hand, when weft count than normal weft count hour, light filling bar just appears in the fabric.
In above-mentioned so common control, during that section of normal operation target warp tension value, for example, can be presented on the display 56 with number of pick up to average warp tension value stabilization.In the illustrated example, start during the change and be 10 and detect Tu (10 cycle period Ts) during the units, promptly 10 throw a spear.
Owing to can calculate the length size of fabric from shown number of pick, the operator just can observe the fabric portions of knitting of making during starting change.According to the observation, the operator just can determine to be formed on the length size of the thick and thin places on the fabric and the variation of weft count.
The operator suppresses thick and thin places for the ride gain by adjustment output motor 32, thereby loom is adjusted.Turn down by the ride gain that will export motor 32, the velocity of rotation of the output motor 32 when suppressing to start changes, thereby presses down the generation of thick and thin places, and such control is exactly following inhibition shown in Figure 10 control.
The length that starts during changing is represented with number of pick, and warp tension control part 58 uses predefined weft count, calculate the length size that starts the fabric during changing, the length size that calculates can be shown in display 56, also can with start change during the relevant information of length size of fabric, for example will start change during demonstration in display 56.
The 5th embodiment
Figure 10 be show that on display 56 loom starts after, the warp let-off control model of warp thread is the coordinate that the velocity of rotation at the variation that suppresses the average warp tension value under the control, output motor 32 changes, the weft count of fabric changes.
And, about Figure 10 (a) shown in following and the variation of Figure 10 (b), can show with numerical value, also can be with the coordinate demonstration as each figure.
In the illustrated example, shown that loom begins to start after, carry out warp thread warp let-off control model, change and weft count changes to the velocity of rotation of the variation of the change time of common control, average warp tension value, output motor 32 from suppressing control.The ride gain of output motor 32 is little values, when for example being 10.And, batch motor after loom starts, rotate with normal rotation speed often.
Because the ride gain of the control of the inhibition shown in Figure 10 (a) is littler than the ride gain of the common control shown in Fig. 9 (a),, continues at leisure to rise, and reach target warp tension value so average warp tension value T compares with Fig. 9 (a).That is, the amplitude of variation of the average warp tension value of the inhibition of Figure 10 (a) control, and the amplitude of variation of the average warp tension value of the common control of Fig. 9 (a) is little.And, owing to suppress the ride gain of control, and littler than the ride gain of common control, so arriving the time of normal operation target warp tension value, average warp tension value to grow.
Figure 10 (b) shows is the variation of velocity of rotation of the output shaft of output motor 32.Because it is littler than the ride gain of control usually to suppress the ride gain of control, so the amplitude that the velocity of rotation of the output shaft of the output motor 32 in the inhibition shown in Figure 10 (b) control changes, the amplitude that changes than the velocity of rotation of the output shaft of the output motor 32 in the common control shown in Fig. 9 (b) is little.And the average warp tension value that suppresses control reaches the time of normal operation target warp tension value, and the average warp tension value of comparing common control reaches the time of normal operation target warp tension value and will grow.
Like this, when being suitable for ride gain than the little inhibition control of control usually, suppress so that control is suitable for during than common control be suitable for during long.But, owing to be suitable for the amplitude that the velocity of rotation of the output motor 32 when suppressing control changes, it is little to compare the amplitude that the velocity of rotation of the output shaft that is suitable for the output motor 32 in the control usually changes, so the amplitude of variation of the weft count of fabric can be done for a short time when being suitable for common control.
Suppressing the termination of control can set by end condition constantly.As end condition, as mentioned above, for example can be the situation that average warp tension value arrives normal operation target warp tension value, perhaps average warp tension value several the throwing a spear that link to each other with normal operation target warp tension value, and situation such as reach unanimity.
The amplitude of variation of the weft count of inhibition shown in Figure 10 (c) control, the amplitude of variation of weft count of comparing the common control shown in Fig. 9 (c) is little.And the weft count the when weft count that be suitable for to suppress be at the highest notch (during the peak) of control period is the normal operation of 51 pieces/cun and loom is much the same.
The operator when producing thick and thin places, confirm from suppress control be carved into when loom starts down be stabilized in till the normal operation target warp tension value during, be about to be suitable for suppress control during in display part, show, confirm pairing number of pick during this period.The operator is according to the number of pick of confirming, the thick and thin places of observing the actual fabric part produces situation, adjusts with this ride gain to output motor 32.
This situation, the operator is not that to dwindle ride gain just passable, is suitable for the length size that suppresses the pairing fabric of control period but will try to achieve.And the operator makes the amplitude of variation, unequal of weft count of the part of the fabric of knitting by confirm to be suitable for suppressing control period on the spot, by rule of thumb the ride gain of output motor 32 is adjusted, thereby is suppressed the generation of thick and thin places.
Like this, inhibition is controlled at when the main cause of thick and thin places generation is relevant with warp tension just effective.When the suitable thick and thin places that suppresses control can't be eliminated, the reduction amount of perhaps judging the average warp tension value on the resume of warp tension value few (perhaps the number of pick that shows of number of pick is few), when warp tension reduction etc. is not main cause, carry out arbitrary speed control shown in Figure 11.
The variation of the 5th embodiment
According to be suitable for to suppress control during, in next loom starts, can judge whether to be suitable for constantly and suppress to control from this startups.In short-term, the reduction amount that just can judge warp tension value T during this period is few during suitable inhibition control.
For example, the operator sets the boundary value of regulation in advance on setting apparatus.When loom control device 40 is judged the warp tension value T of inhibition control before this or average warp tension value big than this boundary value the time, will adopt inhibition to control in knitting making next time.When the loom control device is judged the warp tension value T of inhibition control before this or average warp tension value little than this boundary value the time, just can not suppress to control in knitting making next time.
And, illustrated above to judge whether the situation that suppresses to control in knitting make next time automatically, can certainly judge whether to suppress control again by the operator by observing warp tension value T or average warp tension value.Even the operator can set and suppress optimal ride gain in the control, also can loom control device 40 calculates optimal ride gain automatically and sets.
The 6th embodiment
Figure 11 be on display 56 show that looms start after, the variation of the velocity of rotation of batching motor 46 of the warp let-off control model of warp thread under arbitrary speed control, the velocity of rotation of output motor 32 change, the coordinate of the variation of average warp tension value.And, about Figure 11 (a), Figure 11 (b) shown in following and the variation of Figure 11 (c), can show with numerical value, also can be with the coordinate demonstration as each figure.
In the illustrated example, after having shown that loom starts, carry out warp thread warp let-off control model, from arbitrary speed control change to the velocity of rotation of the time of common change, the variation of batching the velocity of rotation of motor, output motor 32, the variation of average warp tension value.So-called arbitrary speed control is meant by operator's command speed pattern, under the velocity mode of, appointment incoherent with the warp tension value that is detected, and the output shaft rotation of control output motor 32.As the project of command speed pattern, mainly contain velocity of rotation, number of pick.
For example, after loom starts, when producing thick section, the resume of the average warp tension value after the operator confirms to start.If it is that average warp tension value after loom starts has decline that the operator judges, make when knitting next time, after starting, suppress by loom to control so.But, if being suitable for when suppressing control, the thick section warp let-off control model at warp thread still can't eliminate, the operator will replace suppressing control with arbitrary speed control in the warp let-off control model of warp thread so.
Specify, the operator judges: the type section of the thickness of generation is thick section, and average warp tension value has reduction.So the operator sets by setting apparatus 52, make the output motor 32 in loom when running and the velocity of rotation of batching the output shaft of motor 46 become faster.And it is fast that the velocity of rotation of the output shaft of the velocity of rotation specific output motor 32 of operator by making the output shaft that batches motor 46 is also wanted, and improve warp tension value T with this.
Figure 11 (a) shows the variation of the velocity of rotation of the output shaft that batches motor 46.In the illustrated example, 120% of the speed under the setting value of the velocity of rotation of the output shaft that batches motor 46 under the arbitrary speed control is equivalent to control usually.
Figure 11 (b) shows the variation of the velocity of rotation of the output shaft of exporting motor 32.In the illustrated example, 110% of the velocity of rotation under the setting value of the velocity of rotation of the output shaft of the output motor 32 under the arbitrary speed control is equivalent to control usually.
What Figure 11 (c) showed is the variation of the average warp tension value when the velocity of rotation pattern of the output shaft that batches motor 46 and output motor 32 in the loom running is set as described above.In the illustrated example, because the velocity of rotation of batching the output shaft of motor 46 wants the velocity of rotation of output shaft of specific output motor 32 fast, so As time goes on increase gradually of the average warp tension value under the arbitrary speed control.Therefore, the weft count of fabric diminishes gradually.
Like this, shown in Fig. 9 (c) like that after loom starts, in fabric, produce thick section (produce in big thick section) than normal weft count, and, when loom starts, even use to be suitable for suppress control, in the time of still can't eliminating thick section of fabric, by after startup, being suitable for above-mentioned arbitrary speed control, just can press down the generation of thick and thin places.
And, even carried out above-mentioned arbitrary speed control, but from loom start to reach till the normal operation target warp tension value during long, and the average warp tension value of front and back that is altered to the change time of common control from the arbitrary speed control target warp tension value that runs well relatively reduces, and makes the velocity of rotation of output shaft of the velocity of rotation specific output motor 32 of the output shaft that batches motor 46 want fast again.For example, the velocity of rotation that makes the output shaft that batches motor 46 be when controlling usually velocity of rotation 125%, the velocity of rotation of the output shaft of output motor 32 be when controlling usually velocity of rotation 105%.
In addition and since be suitable for arbitrary speed control during be that number of pick by velocity mode decides, so the operator can know in advance be suitable for arbitrary speed control during.When the change that controls to common control from arbitrary speed is carried out continuously as described above, to during the suitable arbitrary speed control (for example 10 throwing a spear), with begin from common control to average warp tension value reach till the normal operation target warp tension value during (for example 5 throwing a spear) add up to, (15 throw a spear) is presented on the display part 56 during this total.But, also can during these two, be presented at respectively on the display 56.With being suitable for the situation that suppresses control replacement arbitrary speed control or be used also is same.
In the illustrated example, be suitable for arbitrary speed control during in, what be suitable for is 1 velocity mode, also can be suitable for arbitrary speed control during in a plurality of velocity modes of continuance of application.
Each numerical value shown in the foregoing description all is an example of supposing for this embodiment is described, actual making has difference when knitting.
The 7th embodiment
Different with the 1st to the 6th embodiment, can be in memory 54 with the average warp tension value memory during any in the loom running, and be presented on the display 56 as resume.
For example, can at any time the average warp tension value in the loom running be remembered in memory 54.This situation, consider the capacity of memory 54, what remember is the average warp tension value that comprises the part past of up-to-date average warp tension value Tu during interior predefined detection unit, can erase at any time and go back Zao average warp tension value than this.
And if the operator presses specific button in the loom running, by that button of pressing, a plurality of average warp tension values in the past of the regulation in being engraved in when comprising this will be remembered in memory 54.
In general, need the huge memory capacity that to remember all average warp tension values in the loom running.But when for example producing thick and thin places in the loom running, the operator just can remember a plurality of average warp tension value of the regulation that begins by pressing the button when thick and thin places produces.
The memory 54 that uses in the memory 54 that uses when pressing specific button and the common running can be different.But, in the memory 54 that the average warp tension value memory that also can should remember when pressing specific button is used in running usually.As long as the content of these memories 54 is not upgraded, will the interior content of persistent memory memory.
When the CRANK PULSES that stops in expression running is input to loom control device 40, can remember the CRANK PULSES input time that comprising that the expression running stops of the average warp tension value before interior regulation several.
As above-mentioned, in the running of loom, produced thick and thin places, when having produced weft crackiness specifically, the operator at least will with on fabric, can confirm thick and thin places during in average warp tension value remember in the memory 54, and the size of the variation by confirming this average warp tension value and having or not of changing, the reason that just can judge the thick and thin places generation still is that yarn (so-called yarn because of, tension force because of) causes by machinery.
At this, so-called weft crackiness is meant with stop segment a kind of thick and thin places different, that produce in the loom running.The reason that weft crackiness takes place is divided into: by (yarn because of) that variation caused of warp tension in inconsistent that cause, the loom running of the volume tension force that is wrapped in many warp thread on the output shaft, and the machinery of the resonance section that causes of the vibration of bad thick and thin places that causes of the maintenance of the let-off motion of warp thread and batching apparatus or loom self etc. because of.
Each above-mentioned embodiment, be to have utilized between the warp tension detection period that is used for calculating under the output control (FEEDBACK CONTROL) and the detection warp tension value of deviation, and used in order to reach the example of the typical value of warp tension during the warp tension monitoring that monitors the warp thread state.But, between the warp tension detection period and during the warp tension monitoring, and the typical value that detects warp tension value and warp tension, can use different separately numerical value, different computational methods and different detection methods.
The present invention is defined in the foregoing description, only otherwise break away from its aim, can carry out various distortion.
