The specific embodiment
Secondly, with reference to Fig. 1～Fig. 7, embodiments of the invention are described.
[the 1st embodiment]
Possessing according to the wind2 in the wire drawing machine of the present invention shown in Figure 1 the 1st embodiment: as the metal wool 1 of long materials; Be used to supply with the supply side spool 2 of this line 1; Roller 3 as the supply side swivel; With roller 3 bonded assembly motors 4, as the inverter 5 of the actuating device of this motor 4; Drawing-die portion is hot candied portion 6; The regulating control tension detector 7 of holding concurrently; Spool 8 as the winding side swivel; With winding side spool 8 bonded assembly winding side motors 9; Inverter 10 as the actuating device of this motor 9; Dispose a plurality of rollers 11～18 on online 1 path; Transverse arm 19; The control setup 20 of supply side inverter 5; And the control setup 21 of winding side inverter 10.
With motor 4 bonded assembly inverters 5 dc voltage conversion of direct supply 5a is become for example sine wave AC voltage of 50Hz.If make the rotation of roller 3 constant speed, then send line 1 with constant linear velocity.
Supply side control device for inverter 20 is used for the frequency instruction f0 of the frequency of control inverter 5, control setup 20 control inverters 5, when beginning the output frequency of inverter 5 is slowly improved with the coiling of convenient line 1, when normal winding, make the output frequency of inverter 5 keep constant, when finishing the output frequency of inverter 5 is slowly reduced when reeling.The rotating speed of motor 4 is directly proportional with the output frequency of inverter 5.In this concrete example, supply side control device for inverter 20 is connected with winding side control device for inverter 21 by line 22.This line 22 is as the speed value feedway of winding side motor 9 and work.
Regulating control and tension detector 7 by: contact with line 1b, as the cylindric press body 7a of regulating control; Evolution on the vertical direction of this press body 7a is become the tension pick-up 7b of electric signal; Guiding device 7c; And extension spring 7d formation, it is configured between roller 3 and the winding side spool 8.Have, line 1b is anti-U word sigmoid between pair of rolls 16,17 again, with the last side contacts of press body 7a.Because the axle of press body 7a is inserted in the groove 24 that extends on the vertical direction as the mounted panel 23 of guiding device 7c, so press body 7a can move up and down in the scope of groove 24.In order to provide tension force for line 1b, press body 7a always is partial to towards the top by extension spring 7d.If the tension force grow of line 1b, then regulating control is that press body 7a moves towards the below, and on the contrary, if tension force dies down, then press body 7a moves towards the top.In this concrete example, the intensity adjustment of spring 7d is become the centre that when optimum tension press body 7a is positioned at groove 24.
Link, also can be described as the tension pick-up 7b of position transduser with press body 7a, as shown in Figure 2, for example be made of variable resistance 25, travelling contact 26 and low-pass filter 27, the voltage Vt that the position with press body 7a is directly proportional detects voltage output as tension force.Variable resistance 25 is connected between terminals for power supplies 28 and the ground, and travelling contact 26 is subjected to displacement with the position of press body 7a with being directly proportional, and it is tension force detection signal Vp that the output body has the position detection signal of short vibration of cycle shown in Figure 3.Low-pass filter 27 is removed high fdrequency component from the output signal Vp of variable resistance 25, level and smooth tension force detection signal Vt shown in broken lines in the output map 3 (A).Have, in this concrete example, tension force detection signal Vt has the value that the tension force with line 1b is inversely proportional to again, and tension force detected value Vt becomes big along with the tension force of line 1b and reduces.
In order to reduce control lag, it is short that the time constant of low-pass filter 27 is set poling, and for example 20～30ms is such.
Winding side spool 8 has the cylindric winding part of radius R, can support spool 8 to get up with rotating freely.With spool 8 bonded assembly motors 9 for example be alternating current dynamos such as induction motor (IM), it is connected with inverter 10.Inverter 10 as motor driver becomes alternating-current voltage/AC voltage to the dc voltage conversion of direct supply 10a, and it is constituted the frequency that can change the alternating-current voltage/AC voltage that motor 9 is supplied with.
Known transverse arm (trarerser) 19 is configured near the winding side spool 8.For line 1b is wound on the spool 8 equably, transverse arm 19 make line 1b from spool 8 axially on an end move to the other end and move in contrast.
Thereby, it is connected with line 22 and tension pick-up 7b as the speed value feedway with the rotating speed of the output voltage of inverter 10 bonded assembly control setups 21 control inverters 10 and frequency control motor 9 and spool 8.This control setup 21 based on the speed command f0 of the synchronous line 22 of supply side inverter 5 and the tension force detected value Vt that obtains from tension pick-up 7b, the output frequency f10 of decision inverter 10.
As Fig. 2 roughly illustrates, winding side control setup 21 by: as the reference voltage source 30 of tension force a reference value generating means; Error amplifier 31 as error signal or deviation signal formation device; Tension force level decision maker 32; Also can be described as the operational ton implementing device 33 of compensation value implementing device; Coefficient multiplier 34; And arithmetic and logic unit 35 constitutes.
The reference voltage V r of the consistent tension force a reference value of the center of expression and press body 7a or original position takes place in reference voltage source 30.An input terminal of error amplifier 31 is connected with tension pick-up 7b, and another input terminal is connected with reference voltage source 30.Thereby the error signal Δ Vt=Vt-Vr of tension force detected value Vt and reference voltage V r takes place in error amplifier 31.
The relation of tension force detected value Vt and the 1st, the 2nd, the 3rd and the 4th tension value Vt1, Vt2, Vt3 and Vt4 shown in tension force level decision maker 32 process decision charts 3 (A), device 32 is by the 2nd, the 3rd and the 4th comparator 36,37,38 and 39 1st; The the 1st, the 2nd, the 3rd and the 4th benchmark voltage source 40,41,42 and 43 as the 1st, the 2nd, the 3rd and the 4th tension value generating means; AND gate 44; And the 1st and the 2nd NOT circuit 45 and 46 constitute.1st, the negative input end of the positive input terminal of the 2nd, the 4th comparator 36,37,39 and the 3rd comparator 38 is connected with error amplifier 31.Cooresponding the 1st benchmark voltage of Vt1-Vr=-V1 with Fig. 3 (A) takes place in the 1st benchmark voltage source 40.Because the negative input end of the 1st comparator 36 is connected with the 1st benchmark voltage source 40, so the output of high level takes place in the 1st comparator 36 when error signal Δ Vt is higher than the 1st benchmark voltage-V1, on the contrary, low level output takes place in the 1st comparator 36 when Δ Vt ratio-V1 is low.Equally, cooresponding the 2nd, the 3rd and the 4th benchmark voltage of the 2nd, the 3rd and the 4th benchmark voltage source 41,42 and 43 generations and Vt2-Vr=+V1, Vt3-Vr=-V2 and Vt4-Vr=+V2.Because negative input end of the 2nd and the 4th comparator 37 and 39 is connected with the 2nd and the 4th benchmark voltage source 41 and 43 respectively, so the output of high level takes place when the voltage of voltage ratio negative input end of separately positive input terminal is high, on the contrary, low level output takes place when the voltage of voltage ratio negative input end of positive input terminal is low.In addition, because the positive input terminal of the 3rd comparator 38 is connected with the 3rd benchmark voltage source 42, so become when hanging down the output of generation high level as tension force detected value Vt than the 3rd benchmark voltage-V2.
From as can be known above-mentioned, the 1st comparator 36 judges that whether tension force detected value Vt is than the 1st tension value Vt1 height shown in Fig. 3 (A).The 2nd comparator 37 judges that whether tension force detected value Vt is than the 2nd tension value Vt2 height.In addition, the 3rd comparator 38 judges that whether tension force detected value Vt is than the 3rd tension value Vt3 height.In addition, the 4th comparator 39 judges that whether tension force detected value Vt is than the 4th tension value Vt4 height.
For judge whether tension force detected value Vt is among the 1st regional Z1 between the 1st tension value Vt1 and the 2nd tension value Vt2, and an input terminal of AND gate 44 is connected with the 1st comparator 36, another input terminal is connected with the 2nd comparator 37 by the 1st NOT circuit 45.Thereby, when the 1st comparator 36 is output as high level, the output of AND gate 44 became high level when the 2nd comparator 37 was output as low level, be judged to be tension force detected value Vt and be among the 1st regional Z1.When tension force detected value Vt leaves the 1st regional Z1, with AND gate 44 bonded assembly NOT circuits 46 high level output takes place.
The 1st operational ton implementing device 33 also can be described as the compensation value implementing device, and the 1st operational ton fa is exported in the processing that the output of error amplifier 31 puts rules into practice.The 1st operational ton implementing device 33 switches the speed of response in the servo loop for the size of relating to tension force detected value Vt and has: 1st, the 2nd and the 3rd switch 47,48 and 49; Integrating circuit 50; Proportional integral (PI) circuit 51; And lock-out circuit 52.
Proportional integral (PI) circuit (PI circuit) 51 as the 2nd time constant circuit is connected with error amplifier 31 by the 2nd switch 48.By the output of the high level of NOT circuit 46 the 2nd switch 48 is carried out conducting control, as the 2nd switch 48 conductings when tension force detected value Vt leaves among the 1st regional Z1 of Vt1～Vt2 as shown in during t1～t3 of Fig. 3 (A).Thereby, during t1～t3 of Fig. 3 (B) in proportional integral (PI) circuit 51 have the 2nd timeconstant 2, error signal Δ Ve is carried out proportional integral (PI) handles, export the 1st operational ton fa.Have, 51 frequency values that are directly proportional with the proportional integral value of error signal Δ Ve of proportional integral (PI) circuit are exported as the 1st operational ton fa again.Owing to set the 2nd timeconstant 2 of proportional integral (PI) circuit 51 forr a short time, so the speed of response the when speed of response when proportional integral (PI) circuit 51 is connected with servo loop is connected with servo loop than integrating circuit 50 is fast than the 1st timeconstant 1 of integrating circuit 50.Thereby as shown in during t1～t2 of Fig. 3 (C), the 1st operational ton fa responds rapidly the variation of the tension force detected value of Fig. 3 (A).
The 3rd switch 49 and lock-out circuit 52 are connected between proportional integral (PI) circuit 51 and the arithmetic and logic unit 35.Control the 3rd switch 49 by the output of the 3rd and the 4th comparator 38 and 39.When this two side of output of the 3rd and the 4th comparator 38 and 39 was low level, the 1st contact a of the 3rd switch 49 connected, the 2nd contact b turn-offs, and proportional integral (PI) circuit 51 is connected with arithmetic and logic unit 35.When a certain side of the output of the 3rd and the 4th comparator 38 and 39 was high level, the 1st contact a turn-offed, the 2nd contact b conducting, and proportional integral (PI) circuit 51 is connected with lock-out circuit 52, gives arithmetic and logic unit 35 output of lock-out circuit 52.Lock-out circuit 52 is connected with proportional integral (PI) circuit 51 by the 3rd switch 49, as shown in during t2～t3 of Fig. 3 (A), when tension force detected value Vt is bigger than the 4th tension force detected value Vt4, and than the 3rd tension force detected value Vt3 hour, the output of lock-out circuit 52 withdrawal ratio integrating circuits 51 is also kept, and gives arithmetic and logic unit 35 the 1st constant operational ton.Have, lock-out circuit 52 is formed, cancellation keeps content when the contact b of the 3rd switch 49 turn-offs.
In this concrete example, arithmetic and logic unit 35 is adders, on the 1st operational ton fa and the 2nd operational ton fb, and the operational ton that output is made of fc=fb+fa.
The 1st operational ton fa is for just when tension force detected value Vt is higher than the reference voltage V r of expression benchmark tension force, and is bigger than the 2nd operational ton fb by the operational ton fc of arithmetic and logic unit 35 outputs, and winding side motor 9 is quickened to control.In contrast, the 1st operational ton fa is negative when tension force detected value Vt is lower than the reference voltage V r that represents benchmark tension force, and is bigger than the 2nd operational ton fb by the operational ton fc of arithmetic and logic unit 35 outputs, and winding side motor 9 is carried out deceleration control.
The output of arithmetic and logic unit 35 is given the inverter 10 of Fig. 1.Inverter 10 is made of the known DC-AC translation circuit and the control circuit of this translation circuit.The control circuit of inverter 10 is controlled inverter 10, so that the output frequency that the operational ton fc that obtains constituting with the frequency instruction of being supplied with by the arithmetic and logic unit 35 of Fig. 2 is directly proportional.In addition, constitute inverter 10, so that this output voltage is directly proportional with output frequency and changes.Be directly proportional with the output frequency of inverter 10 with the rotating speed of inverter 10 bonded assembly winding side motors 9.
Fig. 4 roughly illustrates line 1b to begin to the supply side motor 4 that finishes and the rotating speed F1 and the F2 of winding side motor 9 from coiling.When the to of Fig. 4, slowly improve the output frequency of supply side inverter 5, when t1, make supply side motor 4 become the regulation rotating speed.The rotating speed F2 of the winding side motor 9 shown in Fig. 4 (B) has the relation that is directly proportional with the rotating speed F1 of the supply side motor 4 of Fig. 4 (A) and rises to specified speed FS, thereafter, and along with line 1b is the increase of winding diameter and slowly descending to the coiling amount of spool 8.T2 moment when the coiling that makes line 1 finishes, slowly reduce the speed F1 of supply side motor 4, simultaneously, also slowly reduce the speed F2 of winding side motor 9 from coiling end speed Fe.
Because the coiling of line 1b is undertaken by the tension force of feedback line 1b, so can make the tension force of line 1b roughly keep constant.
, be not limited to always carry out ideally the coiling of line 1b.Sometimes, when the coiling of line 1b begins, when reel finishing and since line 1b to the cinch of spool 8 etc., the tension force abnormal ascending of line 1b or unusual the reduction.If always only connect integrating circuit 50, then the long time constant of Fig. 2 steep variation that can not follow the tracks of tension force changes operational ton fc, might cut off line 1b.Different therewith, in concrete example shown in Figure 2, if tension force detected value Vt leaves from the 1st regional Z1 of the 1st tension value Vt1 to the 2 tension value Vt2, then this routine integrating circuit 51 is connected with servo loop.Because proportional integral (PI) circuit 51 has the timeconstant 2 littler than integrating circuit 50,, can prevent the broken string of principal vertical line 1b so the generation of the tension variation of the rapid line of response 1b of operational ton fc makes tension force return the action of a reference value.
If when tension force detected value Vt steep variation more than the 4th tension value Vt4 of Fig. 3 or the 3rd tension value Vt3 cooresponding with it operational ton fa is taken place, then tension force might exceed or not enough a reference value Vr significantly.In addition, if the output frequency that makes winding side inverter 10 when line 1b breaks sharp, change significantly, then inverter 10 becomes halted state owing to excess current or over voltage sometimes.Therefore, in concrete example shown in Figure 2, if tension force detected value Vt becomes below the 3rd tension value Vt3 or more than the 4th tension value Vt4, then the 1st operational ton fa remains lower limit Lmin or higher limit Lmax shown in Fig. 3 (C).That is, keep becoming the 3rd tension value Vt3 when following or become the output of the proportional integral (PI) circuit 51 of the 4th tension value Vt4 when above, it is exported as the 1st operational ton fa by the 3rd switch 49 when the tension force detected value by lock-out circuit 52.Thereby, can prevent the variation significantly of the 1st operational ton fa, can prevent the cut-out of principal vertical line 1b.In addition, can prevent the excess current or the over voltage of inverter 10.
[the 2nd embodiment]

+V1′＝Vt2′-Vr′
-V2′＝Vt3′-Vr′

In the 2nd embodiment, if tension force detected value Vt steep variation, then the 2nd switch 48 is also connected, and obtains the effect same with the 1st embodiment.
[the 3rd embodiment]
Form the 3rd embodiment wind2, the control setup 21b of control setup 21 distortion becoming Fig. 7 of Fig. 1 and Fig. 2, other is identical with Fig. 1.
Form the control setup 21b of Fig. 7, change connecting portion and the 1st～the 4th benchmark voltage source 40～43 of the 1st～the 4th comparator 36～39 of Fig. 2, other is identical with Fig. 2.Thereby, in Fig. 7,, omit its explanation for being marked with identical symbol with the same section of Fig. 2.
