The numerical key 115 of input value and the return key hurdle 116 that returns a picture before the picture from current setting picture.

Can play moving, 60 ° of startings, picking from normal starting (with the anglec of rotation of main shaft from 300 ° of startings), reversing sky and with selection starting etc. in the loom starting method of setting hurdle 101 inputs.But in illustrated example, being chosen as is just changeing sky and is playing moving.

At this moment, describe simply following about starting method.Above-mentioned normal starting is from 300 ° of starting looms of the anglec of rotation main shaft as the loom main shaft of running operation starting position, simultaneously by beat up regularly (0 ° of angle), utilizes this picking circulation to begin the starting method of picking immediately thus.But on the loom main shaft, the machinery inertial of bringing into play function as the driving shaft of above-mentioned beating device or Warp opening device etc. has become very large load, so-calledly reaches normal running speed from starting loom main shaft and needs to throw a spear about several.According to fabric types, in such process, compare with normal condition that with the low power of beating up the weft yarn of picking to be beaten up be one of reason that produces thick and thin places.

In addition, playing moving as the reversing sky of one of selectable starting method is when loom main shaft during by current running operation position, the power of beating up returns to the starting method of normal operation substantially, is the method for eliminating the improper part of above-mentioned common starting method.Particularly, one carries out running operation, just makes the reversing of loom main shaft with ormal weight (change or more than) low speed, carries out the so-called empty running of beating without picking then in starting loom main shaft, pass through running operation position originally then, thereby be converted to normal operation with picking.But, when use has the weft yarn of retractility,, removed restraining force to weft yarn owing to warp thread or limit yarn opening along with above-mentioned reversing, the lax problem of weft yarn that produces is arranged.

To this, play moving to be to replace above-mentioned low speed reversing and carry out the method that low speed is just changeing, to be to eliminate the method for playing the moving improper part that produces because of above-mentioned reversing sky as the sky that just changeing of the present invention.Method as described below more specifically, promptly make the loom main shaft just change (low speed just changing a job preface) with ormal weight (change or more than) low speed once carrying out running operation, then in starting loom main shaft, till the rotation amount of loom main shaft reaches rotation amount corresponding to the multiple of the repeat number of weave patterns from the position of carrying out running operation originally, carry out playing running (the empty running operation of beating), be converted to normal operation then with picking without the sky of picking.In this external this starting method, from running operation position originally after main axis rotation corresponding to the multiple of the repeat number of weave patterns (promptly corresponding to just change empty play the rotation of number of pick n after), must be converted to the normal operation of beginning picking, its reason is narrated afterwards.

Then, can be from plain weave, twill (2/1,1/2,1/3,2/2,3/1,4/1,3/2 ... Deng), satin weave (5 satin, 7 satin ... Deng), select fabric tissue in the multi-arm line, jacquard weave line.But, in illustrated example, selected 3/1 TWILL CLOTH.

By selecting to set the above-mentioned fabrics tissue, setting apparatus 52 can be confirmed the base weight plural number n0 of weave patterns.The base weight plural number is the main axis rotation revolution (being number of pick) of circulation primary weave patterns, specifically, part as control program is stored corresponding informance as described below in advance, is that " 2 ", twill (2/1,1/2) are " 4 " for " 3 ", twill (1/3,2/2,3/1) as plain weave promptly ... such corresponding informance.Therefore, setting apparatus 52 can be carried out the empty false judgment of beating the input correctness of number of pick n of just changeing of setting and handle (explanation in the back).But, when being multi-arm line and jacquard weave line, because can not special datum repeat number n0, as long as above-mentioned false judgment processing is not just carried out in manually input reference repeat number.

Starting torque acts on the torque of Spindle Motor 40 when being the loom starting, can be converted to 40% and 1200% two grade.But in illustrated example, starting torque has been selected as 1200% high starting torque.

Usually when Spindle Motor 40 is the induction conductivity that constitutes with the super starter motor of what is called,, when running well, carries out the Y type and connect, carry out the △ type during starting and connect in order to change voltage to its coil power supply.Thereby carry out aforesaid two grades of conversions.With this, can improve starting torque.

But except above-mentioned gimmick, also can utilize will be to the known device as frequency converter of the variable more arbitrary value of curtage of motor power supply, can be multistage or infinitely change starting torque.

As just changeing empty number of pick (the empty running operation tail end of the beating) n that beats, setting from the running operation starting position (at this moment, sky is beaten the time started of running operation, is generally 300 °) beat the main axis rotation number of times (that is main axis rotation number) of running operation end as standard to sky.

As just changeing the number of pick tail end of preface (low speed just changing a job) F, setting from the running operation starting position (at this moment, just changeing sky plays moving and then low speed and is just changing a job beginning period of preface) just changing a job main axis rotation number of times (that is main axis rotation number) that preface finishes as standard to low speed.

Beat regularly (empty time started of beating the running operation) θ F of running beginning as sky, set to make and arrive above-mentioned just the changing a job anglec of rotation of the main shaft that preface finishes of the low speed of latitude when counting F of just moving on to and be used as standard.This timing θ F has been set to identical with the running operation starting position in illustrated example, but can change in 20 °～350 ° scope.

As conversion throw a spear n2 and θ G regularly, when making Spindle Motor 40 startings with 1200% torque, setting returns this torque to the anglec of rotation of the number of pick (that is main axis rotation number) of normal 400% torque and main shaft as standard.

As just changeing rotation amount F0, the main axis rotation angle when setting low speed and just changing a job the end of preface is as standard.

Beat running rotation amount Fb as sky, and the main axis rotation amount when using empty end of beating the operation that turns round (, the main axis rotation number) and as standard.

Beat number of pick k as sky, the main axis rotation number when using low speed just changing a job the end of preface is as standard.

So-called braking θ H, the anglec of rotation that setting should produce the main shaft of brake signal S4 is used as standard.

As reversing ON and OFF, set respectively reversing when making the loom action with manual reversing operation begin (ON) and finish (OFF) regularly (anglec of rotation of main shaft) as standard.

[the 1st embodiment of establishing method]

At this moment, calculate about setting apparatus 52 and to judge and control is played the moving relevant necessary value of setup parameter and these parameters are transported to controller a series of processing before with just changeing sky, describe with following accompanying drawing.With reference to shown in 5, the picture of operator's operating and setting device 52 at first, except starting method, fabric tissue, just change empty and beat number of pick n, just change number of pick F and emptyly play running and begin timing θ F etc. and play the moving setting value about just changeing sky, also set starting torque, conversion timing n2, regularly θ G, braking timing, reversing ON and OFF timing, setting apparatus 52 is at first selected its base weight plural number n0 and is temporarily stored this information according to the fabric tissue of setting from above-mentioned stored information, the value with above-mentioned setting is shown in the display frame 100 (step 120) simultaneously.

In Fig. 3 and Fig. 4, setting is just changeing sky and is playing moving and " 3/1 twill ", beats number of pick n as just changeing empty in addition, just changes number of pick F and emptyly play running and begin timing θ F, is set at " 4 ", " 2 ", " 300 " respectively.In addition, base weight plural number n0 and setting " 3/1 twill " corresponding " 4 ".

If all set relevant setting value, then setting apparatus 52 is judged is just changeing whether the empty number of pick n that beats is the multiple (n=n0) (step 121) of base weight plural number n0.At this moment, because the said reference repeat number is " 4 ", so the multiple of base weight plural number n0 is " 4 ", " 8 ", " 12 " ...

If the judged result in the step 121, just change the empty multiple that number of pick n is not a said n 0 of beating, then setting apparatus 52 is set in the methods such as parameter that n sets hurdle 102 by flicker, the empty state (step 122) that number of pick n sets mistake of beating is just being changeed in expression in display frame 100, returns step 120.

Shown in above-mentioned step 121, if just changeing in this a series of processing procedure whether the empty number of pick n that beats is the judgement of the multiple of base weight plural number n0, then can prevent so-called just changeing sky play when moving do not carry out during the picking the setting mistake (from low speed just changing a job preface when beginning to finishing empty setting mistake of beating the main axis rotation amount when turning round operation).

Judged result in step 121, just changeing empty when to beat number of pick n be the multiple of said n 0 (when having set correct setting value n), setting apparatus 52 enters next treatment step, based on the empty number of pick n that beats of the just commentaries on classics of above-mentioned setting, as just changing a job the just commentaries on classics number of pick F and the empty running beginning timing θ F that beats of parameter of preface tail end of relevant low speed, calculate the just commentaries on classics rotation amount F0 that is just transporting the main axis rotation amount of the preface of changing a job as low speed, beat the sky of the main axis rotation revolution of running operation beats number of pick k and beats running rotation amount Fb (step 123) as the sky of the main axis rotation amount in this operation as sky.

Just changeing rotation amount F0, empty beating running rotation amount Fb and the empty number of pick k that beats can reach (3) by following formula (1) (2) respectively and calculate, can correctly set with the value of such calculating.

F0＝F×360+(θF-θS)?……(1)

Fb＝k×360＝θ0 ……(2)

k＝n-F ……(3)

In formula (1), θ S can be position that the running button is operated in reparation that the operator carries out so-called picking mistake or warp thread broken string later on be the running operation angle (in fact, it is 300 °), in this external formula (2), from the running operation position (in fact θ 0 can be, be 300 °) to 60 ° of the anglecs of rotation of beat up regularly (0 °), these values are preestablished.

Then, setting apparatus 52 will calculate just changes rotation amount F0, emptyly beat running rotation amount Fb and sky is beaten parameter n, F and the θ F of number of pick k with setting, arrangement is presented in the display frame 100, simultaneously with the defeated main control unit 54 (step 124) that sends to as controller of these setting values.Utilize such demonstration, the operator can confirm whether the setting of relevant starting is desirable state.

In step 121, make just change empty beat number of pick n be the plural n0 of base weight multiple the reasons are as follows described.

Just changeing the empty number of pick n that beats is just changeing sky to play moving main axis rotation amount (main axis rotation amount in the low-speed running operation and empty main axis rotation amount sum of beating in the running operation), does not all carry out picking during this period.Therefore, begin to carry out from removing as previous circulation (numbering of throwing a spear) of shutting down the weft yarn of reason in order to make the normal operation with picking, must make is just changeing the empty multiple that number of pick n is the repeat number of weave patterns of beating.

For example, the base weight plural number is " 2 " when being plain weave, even but like this little occasion also makes empty setting value of beating the rotation amount Fb of running lathe turner preface be made as 2 times of the plural n0 of base weight or above value, " 4 " that promptly are made as the multiple of " 2 ", " 6 ", " 8 " in order to prevent thick and thin places mostly ...

Therefore, the rotation amount Fb that beats the running operation when sky is when " 3 ", and integral body is just being changeed empty and beaten number of pick n and be set to " 4 ", is just changeing number of pick F and is being set to " 1 ".Such processing can utilize the mistake in the step 122 to show and reset effectively.

In addition, about narrating particularly by following because of setting the wrong improper part that produces.For example, beat the multiple little " 1 " of number of pick n, then produce so-called same shed open (in same Warp opening, being dropped into 2 weft yarns) fault than the plural n0 of base weight if just changeing empty.

On the contrary, if just changeing the empty multiple big " 1 " of beating number of pick n than the plural n0 of base weight, then produce empty shuttle (also not having input) fault at weft yarn of certain Warp opening.

In addition, in step 123, setting apparatus 52 based on predefinedly just changeing empty and beating number of pick n, as just changing a job the just commentaries on classics number of pick F and the empty regularly θ F of running beginning that beats of parameter of preface tail end of relevant low speed, calculate automatically as just changeing sky and play the sky of other setup parameters when moving and beat number of pick k and beat running rotation amount Fb and just changeing sky and playing all rotation amounts (just changeing sky and beating number of pick n) of operation when moving as the sky of the main axis rotation amount in this operation.Thus, the same with above-mentioned steps 121, can prevent conscientiously with these values of manual individual settings the time recurrent set wrong (, the main axis rotation amount of starting operation in all should with corresponding to the rotation amount of the repeat number of weave patterns when consistent, mistake and setting mistake inconsistently) and the empty shuttle that causes or with fabric defects such as shed opens.

Just change the empty number of pick n that beats according to the plural n0 of base weight, be actually 2 values of multiple of throwing a spear the above tens said reference repeat numbers of throwing a spear following.In addition, the sky of the situation input that takes place according to thick and thin places is beaten number of pick K and is just being changeed number of pick F and is respectively the 1 above tens following values of throwing a spear of throwing a spear, and sets for respectively to make two value sums to beat number of pick n consistent with just changeing sky

There is not concrete expression on Fig. 5, but can add following steps, promptly behind parameter setting, judge whether beyond above-mentioned allowed band according to base weight plural number n0, when beyond the scope, setting apparatus 52 or main control unit 54 are carried out urged the fault processing that resets parameter n, F, so that can just change number of pick F and the empty number of pick K that beats as above-mentioned practical setting.

Replacement is carried out from the setting of step 120 to 124 setting apparatus 52 and is handled, and also can make the main control unit 54 that is connected with setting apparatus 52 carry out above-mentioned setting and handle.Reason is also thought: setting apparatus 52 constitutes former state not and shows the information that is subjected to from main control unit 54 side joints and do not judge the information that the operator imports, and intactly be transported to main control unit 54 sides, share the form of a processing part of the relevant setting of the whether good processing of the value of judging above-mentioned setting or the automatic calculating of residue setting value etc. in main control unit 54 sides.

[embodiment of method of operation]

Below, with reference to Fig. 6, be example the picking mistake to take place in the running of loom 10, export picking rub-out signal S7 from finding lost pick circuit 74, the action of the rotating device 50 when starting is described.In addition, the main control unit 54 of the controller that utilization is controlled movably to next operation, by based on rotation amount, and reach, realize this action as the above-mentioned determined rotation amount of each operation tail end as the main shaft of each operation of main shaft angle signal instrumentation of signal of telecommunication input.

Method of operation during starting when Fig. 6 has represented to set the various parameter with value shown in Figure 4.Therefore, throw a spear (in other words, being main shaft 42 rotations 4 circles) the harness motion circulation primary of warp thread with " 4 " as the n0 of the base weight plural number of " 3/1 " twill by loom.

Fig. 6 is also with 1 to 4 the numeral numbering of throwing a spear as the number of steps of weave patterns, is being the schematic diagram of example from removing a series of actions that wrong yarn when the numbering 4 of throwing a spear the picking mistake taking place is converted to normal operation.

With the Warp opening curve of having described briefly, Fig. 6 is with the weft yarn 130 of the correct picking of solid line circle symbolic representation, become weft yarn (the picking wrong yarn) 130a of picking mistake with the dashed circle symbolic representation, with solid line * symbolic representation not by the weft yarn 130b of picking.

When occurring in, the picking mistake throws a spear numbering 4 the time, then from finding lost pick circuit 74 output picking rub-out signal S7.Thus, main control unit 54 at first disconnects CRANK PULSES S1, connects brake signal S4.With this, stop power supply, and make electromagnetic brake 48 actions Spindle Motor 40, loom 10 stops rapidly.The main shaft 42 of loom 10 stops 250 ° of the next one of the circulation that for example picking mistake takes place circulation.

Then, main control unit 54 disconnects brake signal S4, connects reversing alarm S3.With this, loom 10 with the low speed automatic reverse winding to the position of readiness that is used to remove the wrong yarn 130a of picking.The position of readiness of loom 10 can be the anglec of rotation (for example, 300 °) that warp thread is in the main shaft 42 of the state of remaining silent.And on loom, the situation that makes loom be in halted state (holding state) is presented in the display frame 100 of setting apparatus 52, and not shown indicator lamp or the alarm of main control unit 54 drivings reported to the police to the operator.

After the operator arrived in, for the wrong yarn 130a of the picking of removing picking before just stopping loom 10, if this operator presses reversing order button 78, then main control unit 54 was connected reversing alarm S3.With this, loom 10 is with low speed reversing ormal weight and stop at the position of regulation.

The main shaft angle that manually stop loom 10 (being actually main shaft 42) during reversing the above-mentioned first time is that the wrong yarn 130a of picking is exposed to fell 22 and can removes the position of readiness (180 °) of this mistake yarn 130a.With this, finish the preparation that weft yarn is removed, under this state, carry out removing of the wrong yarn 130a of picking.For removing of the wrong yarn 130a of picking, operator self can carry out, and main control unit 52 is automatically carried out from the wrong yarn of picking taking place to a series of actions of removing wrong yarn of picking and then running.

Then, just change sky and play moving position (running operation position) for loom 10 is turned back to, if the operator presses reversing order button 78, main control unit 54 is connected reversing alarm S3 and is made after the loom 10 reversing ormal weights, disconnect reversing alarm S3, and the connection brake signal stops at loom 10 just to change sky and plays moving starting position.This is just changeing sky, and to play moving starting position be to be set in sky in the display frame 100 to beat regularly θ F (300 °) of running beginning.

Then, in order to start loom 10, when the operator pressed effective running button 76, main control unit 54 made loom begin 2 of following explanation by above-mentioned setting and throws a spear that low speed just changes, the 2 empty just commentaries on classics skies of beating of throwing a spear are played moving.

Play when moving just changeing sky, main control unit 54 at first before main shaft is just transferring to rotation amount F0 into its tail end of above-mentioned decision, when disconnecting brake signal S4, is connected positive rotaring signal S2.Thus, loom 10 is without picking, beats state and low speed with the sky that beats up and carries out the low speed preface of just changing a job.

Just changing a job rotation amount that preface carries out main shaft 42 always of above-mentioned low speed becomes the just commentaries on classics rotation amount F0 that is set in the display frame 100 promptly till 720 ° (main shaft take two turns from 300 ° till).

When carrying out just changing a job preface and when the main axis rotation amount that low speed is just changeing 42 beginnings of loom main shaft reaches 720 ° of low speed, main control unit 54 disconnects positive rotaring signal S2 to be made loom 10 stop and finishing above-mentioned low speed just to change, connect its starting ready signal S5 then.With this, loom 10 was carried out the cloth fell corrective action before the following sky that carries out is beaten the running operation.

The cloth fell corrective action is the known method that for example is called as recoil motion, more specifically, undertaken by following, even batch motor 46 or warp let-off motor 44 to positive veer or reverses direction rotation ormal weight, warp thread 26 and fabric 12 are moved to the fore-and-aft direction of their moving directions, and fell 22 is moved.Suitably set according to the state of actual thick and thin places by the operator, can carry out this cloth fell corrective action.

In addition, in illustrated embodiment, can not beat up in the low speed preface of just changing a job yet.More specifically also can be that the attaching parts of configuration clutch etc. between main shaft and beating device make the connection status releasing of beating device and main shaft in this operation.In addition,, also can omit the cloth fell corrective action, not stop loom, make loom carry out the next empty running operation of beating if there is no need.

When finishing the cloth fell corrective action, main control unit 54 when connecting CRANK PULSES, in main axis rotation before the rotation amount Fb as its tail end of above-mentioned decision, connect vacation and knit signal S6.Thus, loom 10 is in starting, and beginning is beaten up without picking ground, what is called is just being changeed the empty running operation of beating.

Thus, Spindle Motor 40 starts with the starting torque (1200%) shown in the torque settings hurdle 105 of display frame 100.Consequently, loom main shaft 42 is driven by high torque (HT).

Beat in the running operation just changeing empty, the rotation amount of main shaft 42 is beaten value on the rotation amount Fb as if reaching the sky that is set in display frame 100, then closes vacation and knits signal S6.Main control unit 54 is after beating up regularly by 0 ° thus, the normal operation operation that loom 10 is transformed into carry out picking.

On the other hand, main control unit 54 is based on the main shaft angle signal, the number of pass times of counting conversion timing θ G (30 °), when this reached the n2 that is shown in display frame 100 and sets conversion on the hurdle 106 and throw a spear the value of n2 by count value, the high torque (HT) (1200%) with starting torque during from starting was converted to the torque (400%) when running well.

As mentioned above, the sky of the reversing that replacement was carried out along be used to prevent thick and thin places is in the past beaten, carry out low speed just changing a job preface and empty these two operations of operation that turn round of beating by making loom, even when use has the weft yarn of retractility, because playing in the moving process at sky just changes, thus can not produce that the sky of following reversing plays in the braking technique to be produced yet " because of the main shaft reversing discharges the limit yarn beat strand be thereby on weft yarn generation relax " this improper part.Consequently, without detriment to the quality of fabric.And, because on setting apparatus, can manually set the tail end of the low-speed running operation in these two operations, so regulate this concluding time (just changeing number of pick F, the empty regularly θ F of running beginning that beats specifically) by the situation occurred ground that meets thick and thin places, thereby can regulate when starting power of beating up to fabric, consequently, compared with the past, can prevent thick and thin places more effectively.

Above-mentioned example is the example of the loom of the expression tail end (in other words being empty beating the beginning period of turning round) of setting the low-speed running operation, but also can be applicable to loom in addition.For example, in can only setting empty formation (promptly can not change the promptly empty loom of beating the beginning form in period that turns round of tail end of low-speed running operation) of beating the running tail end, repeat number by considering weave patterns also changes to its multiple with the concluding time that sky is played running, can change empty length of beating between on-stream period, consequently can regulate when starting the power of beating up fabric.Promptly, according to the present invention, make loom carry out low speed just changing a job preface and empty these two operations of operation and can be of turning round of beating by making with the structure of at least one side's of two operations of manual setting tail end, can meet the tail end that thick and thin places situation occurred ground changes side's operation, and can regulate when starting the power of beating up fabric.Consequently, compared with the past, can prevent thick and thin places more effectively.

In the above-described embodiments, just change sky and play each moving setting value about being set by setting apparatus 52, being used for, their determining method also can be for as described below.

1a: also can be for as follows: promptly replace input just changeing empty beat number of pick n, just change number of pick F and empty beat the running beginning regularly θ F calculate just change rotation amount F0, empty turn round rotation amount Fb and the sky beaten beaten number of pick k, but input just changeing rotation amount F0, empty beating running rotation amount Fb and emptyly beat number of pick k, calculate just change empty beat number of pick n, just change number of pick F and empty beat to turn round begin timing θ F.

2a: also can be for as follows: promptly all manually settings just changeing empty beat number of pick n, just change number of pick F, empty beat the running beginning regularly θ F, just change rotation amount F0, empty turn round rotation amount Fb and the sky beaten beaten number of pick k.

3a: also can be: replace and set the empty regularly θ F of running beginning that beats, even but when precision is not high also out of question, omission is with the function of main shaft angle initialization for as follows.At this moment, the empty running beginning timing θ F that beats is in the predefined value of internal processes, for example makes fixed value as 300 °, and the operator need set is just changeing number of pick F.

4a: also can be for as follows: when being substituted in the repeat number n0 that possesses weave patterns and being the shedding motion of choice menus scope of fabric tissue (, when possessing the plain weave special use or not having weave patterns as dobby device to compile the twill of function or satin weave or special-purpose cam opening device), manual setting is just being changeed empty and is being beaten number of pick n, and is based on the input of fabric tissue or the repeat number automatic setting that selection is derived.

5a: also can be: replace and set as just changing a job the just commentaries on classics number of pick F of preface tail end of low speed for as follows, and calculate clearancen according to the relation of this value and repeat number (just changeing the empty number of pick n that beats) and beat the rotation amount Fb of running, but set the empty rotation amount of beating the operation that turns round and calculate the tail end of low-speed running operation according to this value and repeat number.At this moment and since the operator can according to the strong and weak situation of the thick and thin places sky that directly input and the relation property of the power of beating up are stronger beat the running operation during, so that setting operation becomes is easy.

In the above-described embodiments, about from just change sky play low speed when moving just changing a job preface to sky beat the running operation, again to the transformation control (all being the detection of end of each operation) of thereafter normal operation, can also be by following change.

1b: also can be: replace main shaft signal θ based on continuous generation for as follows, rotation amount by the rotation of the main axis rotation amount in each operation regulation, thereby these operations are finished, but constitute controller (main control unit 54), make the counting main shaft whenever by the specific timing signal that produces when passing through angle, and reach setting by this count value these operations are finished.

Under above-mentioned occasion, also can constitute the control program of main control unit 54, make by importing the timing signal of counting usefulness in addition, and count the input number of times of this signal, thereby finish each operation, also can constitute the control program of main control unit 54, make and finish each operation by other timing signals that behind counting, produced in other main axis rotation angles.

2b: also can be: if the main axis rotation amount (spindle speed) of time per unit does not have deviation and main shaft can be stabilized driving in the main shaft drives of each operation for as follows, then replace rotation amount control, but will change to the form of controlling by the elapsed time to the control form that each operation changes, the form by each operation tail end of time standard setting is also contained among the present invention like this.Promptly the invention is not restricted to be converted to the control form of each operation by the main shaft angle.

[the 2nd embodiment of establishing method]

Fig. 7 be expression all manually input as the just commentaries on classics of setup parameter empty beat number of pick n, just change number of pick F, emptyly beat number of pick k, and judge whether the relation of these setting values unusual, in the time of unusually this situation is shown in the example on the setting picture 100.In this embodiment, beat number of pick n except just changeing empty, just change number of pick F and emptyly play the running beginning regularly the θ F, the operator also manually the setting sky beat number of pick k.

As shown in Figure 7, when having set starting method, fabric tissue, just change empty and beat number of pick n, just having changeed number of pick F, empty when beating running beginning timing θ F and sky and beating number of pick k, the same with the occasion of the foregoing description, setting apparatus 52 is at first selected the base weight plural number n0 corresponding with it from the fabric tissue of selecting, simultaneously parameter n, the F, θ F and the k that set and the base weight of selecting plural number n0 are shown in the display frame 100 (step 130).

Then, setting apparatus 52 is judged is just changeing whether the empty number of pick n that beats is the multiple (n=n0) (step 131) of base weight plural number n0.

If the judged result in the step 131 is not a multiple, then setting apparatus 52 is the same with the occasion of the foregoing description, by making the methods such as parameter flicker demonstration that are set on the n setting hurdle 102, show that in display frame 100 just changeing the empty number of pick n that beats is to return step 130 by the wrong state of setting.

For the judged result in the step 131, when just changeing empty when to beat number of pick n be the multiple of said n 0 (when having set correct setting value n), then setting apparatus 52 enters next treatment step, judge to set just change empty beat number of pick n whether with set just change the addition result consistent (step 135) that number of pick F and sky are beaten number of pick k.

As above-mentioned embodiment is illustrated, should set respectively just changes the empty sky of beating number of pick n and importing according to the thick and thin places situation occurred and beats number of pick K and just changeing number of pick F, wherein: just changeing the empty number of pick n that beats and be according to the plural n0 of base weight, be actually 2 multiples of throwing a spear the above tens said reference repeat numbers of throwing a spear following; Empty beat number of pick K and just changeing number of pick F be respectively the 1 above tens following values of throwing a spear of throwing a spear, and set for and make two value sums to beat number of pick n consistent with just changeing sky.At this moment, judged result for step 135, when sky is beaten number of pick K and just changeed the value of number of pick F sum and just changeing the empty number of pick n that beats when inconsistent, setting apparatus 52 is by making the methods of setting on the hurdle 102,103 and 111 such as parameter flicker demonstration that are set in, setting apparatus 52 is shown in state in the display frame 100 will setting error situation, returns step 130.Thus, because the operator finds to set mistake, so can more correctly set each parameter.

For the judged result in the step 135, to beat number of pick K and the value of just changeing number of pick F sum and just changeing the empty number of pick n that beats when consistent when sky, setting apparatus 52 can be proceeded following processing same as the previously described embodiments.Specifically, calculate as low speed just the changeing rotation amount F0 and beating running rotation amount Fb (step 133) of the main axis rotation angle of preface when finishing of just changing a job as the sky that sky is beaten the main axis rotation amount of running operation when finishing, on picture, show these values side by side, and send these values to controller (step 134).

For the judged result in the step 135, when sky is beaten number of pick K and just changeed the value of number of pick F sum and just changeing the empty demonstration example of playing the display frame 100 of number of pick n when inconsistent, as shown in Figure 8.

On Fig. 8, be that multirow has shown that " setting the wrong number of pick that just changeing beats the additive value of number of pick to beat number of pick inconsistent with just changeing sky with empty at display field 117.Please revise the mistake of setting value." literal.On Fig. 8, picture shows for convenience, has omitted θ F and has set hurdle 104.

Structure as the loom control device, can replace as main control unit 54, batch the control circuit that constitutes respectively by purpose other circuit arrangements such as control device 68, warp let-off control device 70, picking control apparatus, and be generalized into single or multiple universal circuit device.
