But, loom is provided with elements such as menopause tablet, reed, harness cord between generally all can and weaving cotton cloth at warp shaft, can produce friction inevitably between these elements and the warp thread.Consequently the rotation of warp shaft is difficult to correctly be sent to cloth fell, and cloth fell can not correctly move.
Thus, can replace the driving of warp let-off side (warp shaft) and drive and batch side (winding roller).But, though the rotation of winding roller is easy to be sent to cloth fell, can be because the effect highly significant makes drive amount adjust difficulty.
Based on the problems referred to above, the operator is with reference to the strut rail situation (strut rail kind, power etc.) of reality in the reality, and set driving winding roller, still to drive warp let-off axle still be the two switching (selection) and drive amount that driven element such as drives simultaneously.
But, drive amount must be set according to different dwell times, so the data of setting are more.In addition, the setting operation of the anti-locking apparatus of strut rail is not once just to finish, and before strut rail is eliminated, carry out many times.
For example, according to the strut rail situation, drive spinner member from one when another switches, perhaps from a single driving when both drive switching, these drive amount also will change according to switching.In addition, when the strong and weak degree of strut rail changes, also to reset the drive amount of setting according to stop reason.
Above-mentioned technology must have huge quantity data, when setting these huge quantity data, be easy to produce input error, and setting work is loaded down with trivial details.
Summary of the invention

The anglec of rotation of main shaft 46 and coiler motor 54 utilizes encoder 58 and 60 to detect respectively.What detected main axis rotation angle signal S2 and coiler motor rotary angle signal S3 supplied with control coiler motor 54 batches control device 62.In addition, main axis rotation angle signal S2 also is supplied to warp let-off control device 40.
For make by batching axle 32 batch to weave cotton cloth 24 circular velocity faster than 24 the transporting velocity of weaving cotton cloth, batching axle 32 utilizes and receives the torque adjustment mechanism 64 of batching that main shafts 46 rotatablely move and be rotated by slippage bearing (not shown), keeps 24 the coiling tension of weaving cotton cloth.
Before loom starts, control device 40 and 62 is rotated according to the predefined winding roller 28 and the coiler motor 54 of warp shaft 14 rotations and each drive amount of warp let-off motor 34 of making respectively, thereby makes the cloth fell revisal of revisal cloth fell act on the loom 10.
Cloth fell revisal operation is achieved in that multiply by another drive amount with the drive amount of any one in control device 40 and 62 determines another drive amount with respect to the ratio of this drive amount, makes warp let-off motor 34 and coiler motor 54 forward or reverse according to corresponding respectively drive amount.
If arbitrary driving value is X, another drives value is Y, and then the drive amount ratio is the calculated value of mathematical expression Y/X just for another drives value Y and the ratio that drives value X here saidly.In addition, respectively drive value X, the Y that constitute the drive amount ratio are 1 pair 1,2 pair 1 or 1 pair 0 so positive or negative real number value, and the operator can freely set.
In this embodiment, the driving value that batches side and be winding roller (volume clothes roller) is X, and warp let-off side is that the driving value of warp shaft is Y.Driving direction is determined according to the sign symbol of motivation value.The drive amount of winding roller 28 and warp shaft 14 can be regarded the length or the circular velocity of the outer peripheral face of winding roller 28 and the outer layer surface of warp shaft 14 (outer peripheral face of the warp thread of being rolled up) respectively as.
The warp tension T1 of warp thread 12 reality and poor (Tension Difference) Δ T of goal tension T0 when warp let-off control device 40 runs well in order to eliminate, according to speed command V2, drive warp let-off motor 34 and further drive warp shaft 14 rotations corresponding to warp shaft 14 rotary speeies.
Warp let-off control device 40 carries out above-mentioned cloth fell revisal operation according to the drive amount of setting in a period of time before the loom running.
Warp let-off control device 40 according to the drive amount of determining, drives warp let-off motor 34 when starting preparation, when normal operation thereafter, drive 34 rotations of warp let-off motor according to the speed command V3 that carries out revisal by coil diameter signal D.
When batching control device 62 normal operations, drive coiler motor 54 according to the rotate instruction R2 that determines by loom rotation number and weft count etc. and further drive winding roller 28 speed changes.
But when starting preparation,, drive coiler motor 54 according to the drive amount of determining.
As shown in Figure 2, the anti-locking apparatus 70 of strut rail contains the warp let-off control device 40 that constitutes drive circuit and batches control device 62.
The anti-locking apparatus 70 of strut rail that prevents the strut rail generation is indicated the CRANK PULSES S0 of running and is indicated the startup ready signal S4 that starts preparation from main control unit 72 receptions of loom, and the startup preparation end signal S5 and the S6 of end are prepared in the 72 expression startups of supply main control unit.
Starting ready signal S4 is to press running button 74, and the running button signal inputs to that main control unit 72 backs produce, batch thereafter control 62 or warp let-off control device 40 to main control unit 72 inputs start prepare end signal S5, S6 after its output be closed.CRANK PULSES S0 produces when end signal S5, S6 input main control unit 72 is prepared in not shown startup.
In detail, start when preparing, the startup ready signal S4 of ON exports to and batches control 62 and warp let-off control device 40, simultaneously carry out cloth fell revisal operation on control 62 and the warp let-off control device 40 batching, the two starts when preparing end signal S5, S6 to main control unit 72 inputs when batching control 62 and warp let-off control device 40, starting ready signal S4 is OFF, ends cloth fell revisal operation simultaneously.
Start to prepare end signal S5, S6 respectively after starting beamhouse operation and finishing, batch control 62 and 40 outputs of warp let-off control device certainly.
The various data in advance of the drive amount L2 of warp let-off axle 14 are set in setting apparatus 76 when being used for the driving value X of drive amount L1, winding roller 28 and the warp let-off axle 14 of winding roller 28 when determine starting and Y, startup.Warp thread goal tension T0 when being used for the loom normal operation also can be pre-set in setting apparatus 76.Drive such data such as value X and Y for example can be set at 2 pairs 1.
Setting apparatus 76 is when starting preparation, being set as the coiler motor 54 of a drive amount according to factors such as dwell times by the operator is exactly driving value LI and the ratio of driving X, the Y of winding roller 28 furtherly, drive value L1 and corresponding to driving value X, the Y of dwell time, the warp let-off motor 34 of calculating as another drive amount is exactly the drive amount L2 of warp shaft 14 furtherly based on this.
Drive amount L1 and L2 supply with respectively and batch control device 62 and warp let-off control device 40.The driving direction of drive amount L1 and L2 is by its numerical value sign symbol decision.
Drive division 80 and 82 during the CRANK PULSES S0 of ON input, based on various input instructions and signal, is supplied with the addition portion 88 corresponding with rotate instruction R2 that drives respective electrical motivation 54 and 34 and speed command V2 and some input terminals of 90 respectively during running.
Warp thread becomes the value of goal tension T0 with the value output warp tension T1 of the speed command V2 of when running drive division 82 outputs.This speed command V2 carries out revisal by coil diameter signal D.Also and instruction V2 was the same for the value of the revisal work order V3 of drive division 86 outputs when warp thread was used startup, carried out revisal by the coil diameter signal D that imports.
The output signal of addition portion 88 is supplied with counter 92.The addition side input terminal of counter 92 receives the output signal of addition portion 88, simultaneously, and at the coiler motor rotary angle signal S3 of addition side input terminal reception from encoder 60.
The output signal of addition portion 90 is supplied with the addition side input terminal of subtraction portion 96.Rotational speed signal is supplied with the subtraction side input terminal of subtraction portion 96, and this rotational speed signal is detected, pulse-like signal S1 is carried out conversion with frequency/voltage converter (F/V) 98 by tachomotor 42.
The electric current that driver 100 produces corresponding to speed value V1 uses as the amplification circuit that drives warp let-off motor 34.Particularly, driver 100 is the amplification circuit that make warp let-off motor 34 rotation according to the speed value V1 of input, if from the speed value V1 of subtraction portion 96 for just, warp let-off motor 34 just just changes, if for negative, warp let-off motor 34 just reverses.
According to above-mentioned situation, motor 54 and 34 is driven by instruction R2 and V2 respectively when running well, and when starting preparation, is driven by instruction R3 and V3.
After starting preparation (cloth fell revisal work) end, batch control device 62 and warp let-off control device 40 and will start preparation end signal S5 and S6 self-starting preparation drive division 84 and 86 outputs respectively.Start and prepare end signal S5 and not necessarily generation simultaneously of S6.
As shown in Figure 3, (A), (B), (C), (D), (E), (F) and (G) respectively expression carry out cloth fell revisal operation and be the running button signal of strut rail when preventing to operate, start ready signal S4, CRANK PULSES S0, start and prepare end signal, coiler motor speed, warp let-off electromotor velocity and loom rotation number.
As shown in Figure 3, for make weave cotton cloth 24 and warp thread 12 move forward 2mm and 1mm respectively, and make coiler motor 54 and warp let-off motor 34 to the positive direction rotation, two motor 54 and 34 all stop the rotation thereafter, the running of beginning loom.
When loom start to be prepared, drive winding roller 28 and warp thread 14 simultaneously and through same time ground with speed corresponding to predefined driving value, so also can make weave cotton cloth 24 and warp thread 12 with this speed through same time and side by side move.
Consequently, the active force of winding roller 28 and warp thread 14 is applied to the front and back of fell simultaneously, can not produce the confusion of cloth fell like this.In addition, because can make cloth fell always stably move to certain position, so can prevent to produce strut rail.
But, not necessarily leave no choice but do like that.For example, can make winding roller and warp shaft begin rotation simultaneously, make the two one of stop the rotation earlier, so just can make strut rail prevent to operate in the different time periods and carry out.In addition, but also winding roller rotation back warp shaft rotates again, so just can make strut rail prevent to operate and carry out in turn.
In addition, can before startup, import drive amount L1 and drive value X, Y, also can preestablish and drive value and the drive amount L1 corresponding, when starting the preparation beginning, select drive amount L1, calculate another drive amount L2 input then according to dwell time with dwell time.
Also have, also can preestablish the drive amount L1 corresponding and drive value X, Y, calculate drive amount L2 in advance by above-mentioned relation simultaneously, store in advance, start when preparing beginning, can read drive amount L1, L2 according to dwell time corresponding to dwell time with dwell time.
Drive amount L1, L2 or drive value X, Y and also can set and definite according to other key elements that influences strut rail beyond the stop reason.Other will have and stop reason (Weft stop etc.) in advance, factor that warp thread extension etc. when stopping is relevant etc.
For example because of the reason (staplings etc.) beyond the Weft stop when stopping, when not removing weft yarn and starting, the cloth fell state during entry into service is just different with the state that Weft stop and other reasons cause.Also the warp tension when stopping, Warp opening state (degree in crank angle of loom), Warp opening amount are different in the extension of warp thread when stopping in addition.
Therefore, also can set and determine that the driving ratio also can be set by other key elements corresponding to the drive amount of dwell time by other key element.
To shown in Figure 6, is an embodiment of setting apparatus 76 as Fig. 4.
Handling part 110 is connected to memory 116 with central processing unit (CPU) 114, is connected to input part 112 and controller 40,62,72 shown in Figure 2 by input/output port (I/O port) 118 simultaneously.
Drive value X, Y and drive amount L1, L2 and utilize loader 120 to the CPU114 input value, driving value X, Y and drive amount L1, the L2 of input are presented at display 120.Card processor 124 can utilize the card 126 that stores other various information to import to CPU114, on the contrary in order to transmit various information, also can write various information to card 126.
The following describes with the drive amount L1 conduct of batching side and batch the side drive amount, the driving value X of side and the driving value Y of warp let-off side are batched in input, multiply by this situation of drive amount L2 that drive amount ratio Y/X determines warp let-off side with the drive amount L1 that batches side.Certainly the drive amount L2 of also available warp let-off side is as warp let-off side drive amount, the driving value Y of input warp let-off side with batch the driving value X of side, multiply by drive amount ratio X/Y with the drive amount L2 of warp let-off side and determine to batch the drive amount L1 of side.
At first, as shown in Figure 5, entr screen is presented on the display 122, and operator's utilization contains the numerical value of loader 112 inputs of keyboard corresponding to the drive amount L1 of each dwell time section.CPU114 writes memory 116 with the drive amount of input as batching the side drive amount after numerical value input, the while input value is also shown in each hurdle of display screen of display 122.With this state, wait for the ratio setting the Show Button portion 130 of pressing.
In example shown in Figure 5, drive amount L1 dwell time be 0～2 timesharing be 1.0mm ..., dwell time be 22 minutes be 8.0mm when above, drive amount L1 imports by dwell time.In Fig. 5, for more apparent, show the drive amount L1 corresponding promptly just commentaries on classics amount the time with dwell time, also showing each time period drive amount line of expression at upper area with dotted line is the line 134 of the intensity of variation of drive amount model 132.
Among Fig. 5, the longitudinal axis is just commentaries on classics amount (mm), and transverse axis is dwell time (branch).Batch side drive amount model 132 by the stepped variation of dwell time.
The ratio of pressing is set the Show Button portion 130, and CPU114 determines the drive amount L1 of input, writes memory 116, will batch side drive amount model 132 accordingly with dwell time simultaneously and be presented at display 122 like that with solid line shown in Figure 5.With this state, CPU114 waits for the input of batching side and warp let-off side drive value (drive amount ratio) corresponding with dwell time.
Particularly, CPU114 shows the input picture shown in Fig. 6 lower area in order to reach the input of drive amount ratio on the screen of display 122.The operator utilizes the loader 112 that keyboard is arranged, and the driving value of side and the driving value of warp let-off side are batched in input.This driving value batches side and is shown as a reference value 1, can import warp let-off side numerical value, and in Fig. 6 demonstration is that the warp let-off side drive value that the operator imports is 1.5.
At Fig. 6, can independently import by dwell time and drive value, but also can be made as and the irrelevant same numerical value of dwell time.In addition, also can be other numerical value beyond 1 (be not limited on the occasion of, also can be negative value) as the side drive amount of batching of reference side, batch side and warp let-off side respectively drive value also be not limited on the occasion of, also can be negative value or 0.
If the drive amount L1, the L2 that set or determine be negative value, the drive amount of setting with respect to winding roller or warp shaft just is not the amount of commentaries on classics and be the counter-rotating amount just, and the result of winding roller or warp shaft inversion driving was that cloth fell retreats when loom started preparation.
The operator according to dwell time from input part 112 input warp let-off side drive values to CPU114, CPU114 writes memory 116 with the driving value of the input shown in Fig. 6 lower area, is simultaneously displayed in each hurdle of screen of display 122.With this state, CPU114 waits for that pressing drive amount sets the Show Button 136.
Among Fig. 6, the warp let-off side drive value that batched the side drive value and be 1 o'clock is 1.5 when dwell time is 0～2 minute ..., be to be 1.5 more than 22 minutes the time in dwell time.
At the upper area of Fig. 6, show and multiply by 1.5 times of warp let-off side drive amount models 140 of representing with inclined dashed line that obtain batching side drive amount model 134.Among Fig. 6, the longitudinal axis is just commentaries on classics amount (mm), and transverse axis is dwell time (branch).
Press drive amount and set the Show Button 136, the driving value that CPU114 will import is as the drive amount ratio of batching side and warp let-off side, write memory 116, the warp let-off side drive amount model 140 with corresponding dwell time is presented at display 122 simultaneously, shown in the inclined dashed line of Fig. 6 upper area.With this state, CPU114 waits for and presses automatic setting the Show Button 142.
Among Fig. 6, the longitudinal axis is just commentaries on classics amount (mm), and transverse axis is dwell time (branch).The upper area of Fig. 6 also shows and batches side drive amount model 132 and intensity of variation 134 thereof.
Press automatic setting the Show Button 142, CPU114 is based on the side drive amount of setting in dwell time of batching and batch side and each drive amount ratio of warp let-off side, corresponding dwell time is calculated warp let-off side drive amount, the warp let-off side drive amount of calculating writes memory 116, with such shown in warp let-off side drive amount model 138 image patterns 7 upper areas, be presented at display 122.
When batching the side drive amount is L1, and batching the side drive value is X, and when warp let-off side drive value was Y, warp let-off side drive amount was Y/X with respect to the drive amount ratio of batching the side drive amount, and it is that L2=L1Y/X calculates that warp let-off side drive amount L2 just can be multiplied each other by two formulas.CPU114 reads every value (parameter) according to the dwell time section from memory 116 and calculates, and determines warp let-off side drive amount L2.
Among Fig. 7, the longitudinal axis is just commentaries on classics amount (mm), and transverse axis is dwell time (branch).In Fig. 7, warp let-off side drive amount model 138 is by the stepped variation of dwell time.
Batch side and the warp let-off side drive amount having set and determined are read out to controller 40,62,72 etc. starting when preparing.
Loom when running, in the startup set-up procedure of before the running beginning, carrying out, utilize winding roller and warp shaft to carry out strut rail to prevent operation based on batch side drive amount L1 and the warp let-off side drive amount L2 that determine.The operator will prevent that the setting of operating from being confirmed according to the strut rail situation of reality about strut rail, proceed simultaneously, finish if set, and just begin real loom running.
Strut rail prevents to operate relevant setting, considers following situation.For example, with the irrelevant certain proportion change warp let-off side drive amount of dwell time the time, variable warp let-off side drive amount ratio based on batching the relation of side drive amount with each driving value ratio, is calculated warp let-off side drive amount again.
In addition, with same ratio change certain specific dwell time batch side and the warp let-off side drive amount time, the drive amount of the corresponding dwell time of variable reference side based on the drive amount of change and the relation of each driving value ratio, is calculated warp let-off side drive amount again.
The foregoing description is to be benchmark to batch the side drive amount, has determined warp let-off side drive amount, can warp let-off side drive amount be benchmark also on the contrary, based on warp let-off side and batch the driving value ratio of side, determines to batch the side drive amount.
To batch the side drive amount is that the warp let-off side drive amount that benchmark is determined can be used as a reference value when the anti-locking apparatus of strut rail is thereafter set.For example, loom was set by batching side setting strut rail and is prevented to operate originally, can be as background technology discloses, prevent operation by the strut rail that batches the side setting, drive amount is sent to cloth fell, because fabric can make drive amount be difficult to adjust, so, must set strut rail by effect warp let-off side more slowly separately again and prevent operation.
Like this, as benchmark, be set at 0, batch side and all be made as 0, can have only warp let-off side to act on separately corresponding to the drive amount of dwell time with respect to the side drive value that batches of warp let-off side with warp let-off side drive amount.In addition because warp let-off side separately effect is insufficient, and the strut rail that needs uncoiling again to get side is when preventing to operate, the driving value of side is batched in input, is benchmark with warp let-off side, calculates the drive amount of batching side again.
Each drives value (each drive amount ratio) and can set and determine by whole dwell times, also can All Time be divided into several time periods as embodiment, sets and definite by each time period.The latter's situation, driven element can be identical in the direction of rotation of adjacent time period, also can be opposite.
Utilize the strut rail of winding roller and warp shaft to prevent operation, be not limited to operation once, also can carry out the operation more than 2 times.The 2nd later strut rail prevents operation, is not limited to the driving with for the first time same direction, also rightabout driving or based on the driving of different driving amount.This situation can be operated corresponding to each, in the ratio of a drive amount of operating and setting and each drive amount.
About setting the method for more simplifying is to be benchmark with primary drive amount, set for the second time later drive amount ratio with respect to this, only set primary drive amount, for the second time later drive amount with the first time drive amount multiply by corresponding driving amount ratio and calculate.
Equally, batch the direction of rotation of the driven element of side and warp let-off side can be identical also can be opposite.
The present invention also is applicable to loom when stopping or when start preparing, carry out shedding motion corrective operations, superly start, the back starts (idle running) and waits other strut rails to prevent the situation of operating.
In the foregoing description, detect the tension force of all warp thread pieces, also can only detect the tension force of a part of warp thread.Can detect the inclined degree of rear roller 16 as warp tension, also can detect the displacement of rear roller 16, also can detect rear roller 16 in addition: the inclination of the contact warp thread or the element of weaving cotton cloth and displacement etc. with external component, for example.
Each machine as setting apparatus or controller can be used the machine that is made of separate hardware, the also available general-purpose machinerys such as computer that its function is handled with software.Particularly, warp let-off control device 40 and batch the alternative independently circuit of control device 62 and constitute, and adopt the universal circuits such as computer that its function is handled with software.
The invention is not restricted to above-mentioned embodiment, only otherwise break away from purport, can do numerous variations.
