Send motor 34 and carry out the corresponding driving of revolution with loom main shaft (not shown) by the warp thread carrying device with warp thread transfer device function, coiler motor 38 carries out the driving corresponding with the revolution of loom main shaft by the batching apparatus of weaving cotton cloth.
Each heddle (heald) 18 moves back and forth up and down by the motion changing mechanism of the not shown gyration of accepting spindle drive motor or definite-purpose motor, makes warp thread 12 upper and lower openings.The motion changing mechanism of the gyration of reed 20 by accepting spindle drive motor or definite-purpose motor is swung, and will drop into fell 22 to the weft yarn of the opening picking of warp thread 12.
Loom 10 can be by sending the forward or reverse of motor 34, with warp thread 12 from send through axle 14 send or package in sending through axle 14, warp thread 12 is moved to the place ahead or the rear of its moving direction.The tension force of warp thread 12 weakens from sending when axle 14 is sent at warp thread 12, and package increases when sending through axle 14.
The warp thread carrying device that motor 34 is sent in driving comprises: the operation control section 40 of motor 34 rotating speeds is sent in (when weaving running) control when turning round usually; Usually send the manual operation unit 42 of motor 34 in the time of beyond the running with manual operation; And the driving loop 44 of motor 34 is sent in driving.
CRANK PULSES S1 is the signal whether expression loom 10 is working, and connects when loom 10 is being worked, and cuts off when stopping.The never illustrated main control unit of this CRANK PULSES S1 is supplied with to operation control section 40.
The tension force that acts on warp thread 12 is detected by tension pick-up 46 as a kind of load that acts on jockey pulley 16, supplies with to operation control section 40 as tension signal S2.
The coil diameter of sending through axle 14 that reduces gradually along with sending of warp thread 12 is detected by coil diameter sensor 48, supplies with to operation control section 40 and manual operation unit 42 as coil diameter signal S3.The revolution amount of sending motor 34 is detected by encoder 50, supplies with to driving loop 44 as revolution amount signal θ.
Stop signal S4 is a kind of signal that makes loom 10 stop usefulness when shutdown reasons such as picking mistake and cracked ends yarn take place, is to export the signal of connecting during loom is in halted state, supplies with to manual operation unit 42 from main control unit.
Operation control section 40 is connected with setting value device 52, and this setting value device 52 preestablishes the necessary data of Tension Control of the warp thread such as rotating speed of target 12 of target warp tension, target picking density, loom.
Operation control section 40 is (during importing the CRANK PULSES S1 of connection) between the common on-stream period of loom, the root a tree name is set in various data, tension signal S2 and the coil diameter signal S3 in the setting value device 52, command signal (speed command signal) S5 of the speed value of the deviation of output expression elimination target warp tension and tension signal S2, control model signal (speed control mode signal) S6 of the speed control usefulness of motor 34 is sent in output simultaneously.
For the occasion (during importing the stop signal S4 of connection) beyond can be when the common running of loom is sent motor 34 with manual operation, manual operation unit 42 with just change button 54 and invert button 56 is connected, the while is connected with setting value device 52 again,
Just changeing button 54 and invert button 56 all is to be made of press button, during machine, on during machine, when knotting, in the time of need sending motor 34 (, warp shaft 14) forward or reverse when passing etc., press by the operator.
Press when just changeing button 54, at this moment send motor 34 and should just change, just changeing button signal S54 and connecting.When pressing invert button 56, at this moment send motor 34 and should reverse, invert button signal S56 connects.
Command signal S5 and S7 supply with to driving loop 44 by the portion 58 that adds, and control model signal S6 and S8 supply with to driving loop 44.But in fact, command signal S5 and control model signal S6 only just supply with to driving loop 44 when common running, and command signal S7 and the control model signal S8 occasion beyond only when loom turns round is usually just supplied with to driving loop 44.The speed value of manual operation unit 42 usefulness and torque instruction value are pre-set in manual operation unit 42 in illustrated embodiment, but also can be pre-set in setting value device 52.
Driving loop 44 has: receive the motor controller 60 that motor 34 is sent in command signal S5, S7, control model signal S6, S8 and angle of revolution signal θ rear drive; And the current sensor 62 that detect to flow to the electric current of sending motor 34, detection signal S9 is supplied with to motor controller 60.
60 various input signals of a tree name of motor controller will make by the control model corresponding with control model signal S6 or S8, according to command signal S5 or S7 and send the electric current that motor 34 forward or reverse are used, to sending motor 34 outputs.This motor controller 60 adopts the structure of servo control loop, carries out drive controlling to sending motor 34.
In the common running of loom, control model signal (speed control mode signal) S6 of command signal (speed command signal) S5 of expression speed value and expression speed control mode supplies with to motor controller 60 from operation control section 40.Thus, motor controller 60 just changes while carry out speed control by speed control mode, according to the command signal S5 from operation control section 40.
In case in loom stops, pressing and just changeing button 54, then during it, make and send motor 34 and just changeing (promptly, weaken towards the tension force that acts on warp thread 12 direction revolution), the control model signal S8 of the command signal S7 of expression speed value and expression speed control mode supplies with to motor controller 60 from manual operation unit 42.Thus, motor controller 60 press just change button 54 during, carry out just changeing while send motor 34 corresponding to the control of the speed of command signal S7.The result is that warp thread 12 is sent from warp shaft 14.In case ending is just changeing pressing of button, sends motor 34 and stops.
Otherwise, in case in loom stops, pressing invert button 56, then during it, send motor 34 counter-rotatings (promptly, turn round towards the direction that the tension force that acts on warp thread 12 increases), at first supply with the command signal S7 of expression speed value and the control model signal S8 of expression speed control mode to motor controller 60 from manual operation unit 42, secondly, supply with command signal (torque instruction signal) S7 of expression torque instruction and control model signal (the torque control model signal) S8 of expression torque control model from manual operation unit 42 to motor controller 60, to replace speed command signal and speed control mode signal.
Thus, motor controller 60 press invert button 56 during, make and send the speed value of motor 34 according to and instruction signal S7 correspondence, reverse while carrying out speed control, then, make and send the torque instruction value of motor 34, reverse while carry out torque control according to and instruction signal S7 correspondence.The result is that warp thread 12 is wrapped on the warp shaft 14.In case end pressing of invert button 56, send motor 34 and stop.
As mentioned above, by the control in the common running or the manual operation in stopping to carry out weakening the control of direction (positive veer) towards warp tension, this control is by speed command signal is supplied with to motor controller 60, is made by speed control mode and sends motor 34 and just changeing.
Otherwise, undertaken towards the control of warp tension augment direction (reverse directions) by the manual operation in stopping, this control is by speed command signal is supplied with to motor controller 60, make by speed control mode and to send motor 34 counter-rotating, and then by torque instruction signal is supplied with to motor controller 60, make by the torque control model and to send motor 34 and reverse.
Above-mentioned this relation to motor controller 60 command signal of importing and the control model of being carried out by motor controller 60 of sending motor 34 sees table 1 for details.
Below, further describe loom in stopping by the action of just changeing the manual operation unit 42 that button 54 or invert button 56 carry out.
In loom 10 stopped, operation control section 40 is output signal S5 and signal S6 not.Like this, drive 44 a tree names in loop, drive and send motor 34, if not output signal S7 and S8, then make and send motor 34 and stop by stopping control model from manual operation unit 42 signal supplied S7, S8.
In loom stops, just changeing button 54 in case press, then during it, manual operation unit 42 is exported speed command signal and speed control mode signal respectively as command signal S7 and control model signal S8.The speed command signal of this moment is determined by the various data and the coil diameter signal S3 of setting value device 52, so that the translational speed of warp thread 12 becomes predefined value.Thus, driving loop 44 on one side makes and sends motor 34 and carry out speed and control and just change.
In case press invert button 56, then during it, manual operation unit 42 is at first exported fixing time speed command signal and speed control mode signal respectively as command signal S7 and control model signal S8, then, torque instruction signal and torque control model signal are exported as command signal S7 and control model signal S8 respectively.
Speed command signal when pressing invert button 56 is determined by the various data and the coil diameter signal S3 of setting value device 52, so that the translational speed of warp thread 12 becomes predefined value.Again, torque instruction signal is determined by the various data and the coil diameter signal S3 of setting value device 52, so that the tension force of warp thread 12 is no more than the feasible value of the upper limit.
Thus,, then drive loop 44 and at first make and send motor 34 counter-rotatings, passed through institute and made its counter-rotating by torque control after fixing time by speed control in case press invert button 56.
Press just change button 54 and invert button 56 after, press in case end it because the input of the button of manual operation unit 42 becomes cut-out, stop the control model signal so control model signal S8 switches to from speed control mode signal or torque control model signal.Thus, driving loop 44 will send motor 34 and stop.
Can make as a kind of consideration and send motor 34 and begin after the input of invert button signal to turn round, switch to that torque is controlled and during fixed, can be set in advance in the manual operation unit 42 period that switches to torque control usefulness from speed control.
But during this both the root a tree name decide from the elapsed time of speed control beginning, but also the root a tree name is sent the revolution amount of motor 34 or the actual value of rotating speed decides.Again, the value of torque instruction signal (torque instruction value) is set in the scope that cracked ends yarn accident can not take place.
Motor normally can not turn round when detent torque is not enough.Therefore, torque instruction value (warp tension value) too hour is sent motor 34 and still is in halted state.Otherwise, when torque instruction value is too big, can not control the rotating speed of sending motor 34, exist because of the moment of inertia of drive system rotating danger out of control.
Yet, as mentioned above, when pressing invert button 56, switch to torque control in case will send the control of motor 34 after the speed control, send motor 34 and start reliably by speed control.In case travel to torque control, then send motor 34 and be controlled so as to the state that can not surmount torque instruction value by the torque of its generation.
Torque instruction value is set to not the appropriate value in can the scope of cracked ends yarn, thus, can prevent to proceed mistakenly warp thread and batch caused cracked ends yarn accident under the state of high-tension.
Fig. 2 is the program 1 of expression invert button 56 during being pressed to t2 since moment t1, the program 2 during being pressed to t4 since moment t1 and be pressed to t5 since moment t1 during program 3 in, set the speed of sending motor when making the torque mode signal be changed to on-state and the variation example of warp tension for by moment t3.
In program 1, because of removed pressing of invert button 56 before early than moment t3, sending motor becomes counter-rotating by speed control, stops control since moment t2.In program 2 and 3, because of after moment t3, removing pressing of invert button 56 respectively, switch to torque control since moment t3 and reverse so send motor.Since moment t4 and t5 stop control thereafter.Specifically, in program 3, after moment t4, warp tension rises gradually, and warp tension and the output torque of sending motor are coincide, and the result sends motor to become halted state, thereafter, stops control since moment t5.
That Fig. 3 represents is aforesaid, begin when pressing invert button 56 to switching to an embodiment of the manual operation unit 42 of torque control through performed behind the certain hour from speed control, and Fig. 4 is illustrated in the waveform example of each signal in this manual operation unit 42.
Stop signal S4 be to " with " loop 70 and a side's of 72 input terminal supplies with, just changeing button signal S54 and be to " with " the opposing party's in loop 70 input terminal supplies with, invert button signal S56 be to " with " the opposing party's in loop 72 input terminal, " with " loop 74 1 sides' input terminal and nondisjunction loop 76 1 sides' input terminal supply with.
The speed value V1 that uses when sending the motor counter-rotating is set in respectively in the setting apparatus 80 and 82 that is connected with the instruction efferent 78 that reverses with torque instruction value Tq1.Sending the speed value V2 that is using when motor is just changeing is set in and just changes the setting apparatus 86 that is connected of instruction efferent 84.
" with " output signal in loop 70 is to nondisjunction loop 76 the opposing party's input terminal and just changeing instruction efferent 84 and supplying with.On the other hand, the speed control mode signal S84 when just changeing button 54 and press is from manual operation unit 42 outputs." with " output signal in loop 72 supplies with to switching signal generating unit 88.
Switching signal generating unit 88 has connects positive delay timer 92, this connect positive delay timer 92 from " with " after the output signal in loop 72 begun to pass through the time T of setting the setting apparatus 90 1 when rising, the signal that output is connected.The output signal of connecting positive delay timer 92 by logic inversion device 94 to " with " loop 74 the opposing party's input terminal supplies with.
From " with " loop 74, when connecting the connection signal that obtains the output in positive delay timer 92 and nondisjunction loop 76 and pressing as invert button respectively speed control mode signal S81, torque control model signal S82 and stop control model signal S83 when not pressing the button, from manual operation unit 42 outputs.Speed control mode signal S81 and torque control model signal S82 also supply with to counter-rotating instruction efferent 78.
In loom stops, in case just changeing button signal S54 connects, then manual operation unit 42 with speed value V2 as command signal S7, from just changeing the output of instruction efferent 84, simultaneously will from " with " the speed control mode signal S84 of loop 70 outputs exports as the control model signal.
In loom stops, in case invert button signal S56 connects, then manual operation unit 42 is during time T 1 thereafter, cut off from the output signal of connecting positive delay timer 92, will from " with " the speed control mode signal S81 that exports of loop 74 exports as the control model signal.During this period, manual operation unit 42 as command signal S7, is exported speed value V1 from counter-rotating instruction efferent 78.
In case invert button signal S56 begins to have passed through time T 1 after connecting, then connect, so the torque control model signal S82 that manual operation unit 42 will obtain from connect positive delay timer 92 outputs exports as the control model signal because of the output signal of connecting positive delay timer 92.During this period, manual operation unit 42 as command signal S7, is exported torque instruction value Tq1 from counter-rotating instruction efferent 78.
When just changeing button signal S54 and after connection, being cut off and invert button signal S56 when after torque control, cutting off, because of the output signal in nondisjunction loop 76 is connected, so the control model signal S83 that stops that manual operation unit 42 will obtain from 76 outputs of nondisjunction loop exports as the control model signal.During this period, manual operation unit 42 output instruction signal S7 not.
Fig. 5 represents that the root a tree name sends the actual value of the revolution amount of motor, the decision embodiment from the switching signal generating unit 88 of the speed control occasion between the transfer period of torque control.
In switching signal generating unit 88 shown in Figure 5, in the stopping of loom, in case press invert button, then according to " with " output signal in loop 72 makes integrating instrument 100 starts, the revolution amount signal θ that sends motor is added up, and comparison loop 102 is made comparisons aggregate-value and the revolution amount threshold value that is pre-set in threshold setting device 104.
Revolution amount threshold value be a kind of with from speed control corresponding value between the transfer period of torque control.Thus, whether comparison loop 102 arrives under the corresponding state of revolution amount threshold value with aggregate-value, the signal output that switches on or off.
Specifically, the output signal of comparison loop 102 is kept dissengaged positions when aggregate-value no show revolution amount threshold value.Thus, manual operation unit 42 output speed control model signals.But in case aggregate-value arrives revolution amount threshold value, then the output signal of comparison loop 102 is connected.Thus, manual operation unit 42 output torque control model signal S82.
Fig. 6 represents that the root a tree name sends the actual value of the speed of gyration of motor, the decision embodiment from the switching signal generating unit 88 of the speed control occasion between the transfer period of torque control.
Switching signal generating unit 88 shown in Figure 6 is transformed to the rotating speed of sending motor with the revolution amount signal θ that sends motor in F/V converter 110, the rotating speed after the conversion is supplied with to shutter 112.In this switching signal generating unit 88, in the stopping of loom, in case press invert button, then according to " with " output signal in loop 72 makes shutter 112 starts, will be from the rotating speed input comparison loop 114 of F/V converter 110, in comparison loop 114, make comparisons with the speed of gyration threshold value that is pre-set in threshold setting device 116.
Rotary speed threshold value be a kind of with from speed control corresponding value between the transfer period of torque control.Thus, whether comparison loop 114 arrives under the corresponding state of speed of gyration threshold value with the rotating speed of sending motor, the signal output that switches on or off.
Specifically, the output signal of comparison loop 114 is kept dissengaged positions when sending the rotating speed no show rotary speed threshold value of motor.Thus, manual operation unit 42 output speed control model signals.Arrive rotary speed threshold value in case send the rotating speed of motor, then the output signal of comparison loop 114 is connected.Thus, the torque control model signal S82 of manual operation unit 42 output connections.
In the above-described embodiment, press just change button or invert button during, send and just change button signal or invert button signal, but just change button or invert button by pressing, also can send institute and fix time and just change button signal or invert button signal.
Again, be not to send by just changeing the operation instruction signal that button signal or invert button signal are formed with button yet, but use instead by the instruction of not shown controller for example, automatically take place and above-mentioned button signal or the invert button signal instruction corresponding signal of just changeing by passing command device, drive sending motor.
