Spool is provided with platform 55 to have rotation and spool SP is set freely, transmits the mechanism that the rotation from coiling rotary driving part 56 drives.In addition, coiling rotary driving part 56 is to make spool SP with driver elements such as the Spindle Motor of specified speed rotation, vector motor, general motor, servomotors.
Welding wire reeling device 1 as the above explanation that physical construction is done; On dance roller equipment 10, be situated between and move wheel 12 by driving cylinder mechanism 25 up and down supports freely; It is constant that control mechanism 26 control loaded of explanation below using are simultaneously given the tension force of welding wire W, therefore can grant constant tension force to welding wire W all the time and welding wire W is recoiled on spool SP from winder BW.Also having, in the welding wire rewind 1, is that the reel of the reel footpath that makes reel 31, tight pulley 11 directly reaches the reel that the reel that moves wheel 12 directly is equal to or greater than spool SP and directly forms at this.Constitute according to this, can make the load that welding wire W is granted unnecessary plastic deformation is irreducible minimum.
Next, describe about control mechanism 26.As shown in Figure 3, control mechanism 26 possesses according to mobile wheel 12 positions of being detected by sensor 19 to the rotative speed control mechanism 26A that extracts rotary driving part 4 out and control with according to the driving cylinder control mechanism of driving cylinder mechanism 25 being controlled from the signal of the member 40 that traverses 27.Also have, control mechanism 26 is that the form of the composition that also possesses display unit 28 is described at this, and display unit 28 is inputs from the signal of the expression speed of wire speed testing agency 30 and is presented on the display monitor 29.
Rotative speed control mechanism 26A is detection position when being in than desired location near the position side of tight pulley 11 in the result of detection position and the desired location comparison of setting of the mobile wheel 12 of input, and the control of carrying out is to slow down from the present speed of extracting rotary driving part 4 out.In addition, rotative speed control mechanism 26A is detection position when being in than desired location away from the position side of tight pulley in the result of detection position and the desired location comparison of input, and the control of carrying out is to quicken from the present speed of extracting rotary driving part 4 out.
This rotative speed control mechanism 26A possesses input block 26a, memory cell 26b, identifying unit 26c and output unit 26d.
What memory cell 26b stored is to become the predetermined desired location (threshold value) that the benchmark of wheel 12 is moved in control.This memory cell 26b is made up of certain the common memory cell such as simulation basal disc with settings such as hard disk, memory device, mediums.
Identifying unit 26c is being that threshold ratio result is that the detection position is when being in than desired location near the position of said tight pulley side from the value of the detection position of input block 26c output with being stored in desired location the memory cell 26b; The Feeding speed of judging welding wire W is fast; In addition; In the value of detection position and threshold ratio result is detection position when being in than desired location away from the position of said tight pulley side, judges that the Feeding speed of welding wire W is slow.And identifying unit 26c exports to output unit 26d with the result of its judgement.
Because rotative speed control mechanism 26A such as above formation; Therefore via the detection position of input block 26a input with the mobile wheel 12 of sensor 19 detections; Utilize identifying unit 26c that the detection position of input is compared, judges with the desired location (threshold value) that is stored among the memory cell 26b in advance; Signal according to its result of determination of exporting from output unit 26d is controlled extracting rotary driving part 4 out; Thereby it is constant that the plastic deformation that is wound on tight pulley 11 and moves the welding wire of 12 on wheel is remained, and can grant constant tension force all the time.
Next, describe about driving cylinder control mechanism 27.Driving cylinder control mechanism 27 is control driving cylinder mechanisms 25 when coiling welding wire W on spool SP.This driving cylinder control mechanism 27 possesses welding wire detection position input block 27a, memory cell 27b, welding wire detection position identifying unit 27c and driving cylinder control signal output unit 27d.Also have, this driving cylinder control mechanism 27 in this formation is, position signal (position that welding wire W is horizontally slipped) the controlling and driving cylinder mechanism 25 that sends according to the sensor (not have to illustrate) from the member 40 that traverses.
What welding wire detection position input block 27a imported is the position signal that the member 40 that traverses that distributes about welding wire W is sent from the width range of spool SP.Also having, for example is the signal with the shift position of the portion that moves back and forth 42 of sensor (not diagram) detection sway welding wire W from the position signal of the member 40 that traverses.
Also have, switching position can change arbitrarily from its first switching position to the, four switching positions, and the member 40 that traverses will be reversed becomes high pressure before soon in sometime after counter-rotating, thereby, have and suppress the effect that vibration takes place welding wire.In addition, when switching position was left-right symmetric, it was just much of that to store 2 switching positions.
There was hysteresis in the switching position that is stored among the memory cell 27b before driving cylinder mechanism 25 switches to base pressure or high pressure according to signal, calculate this hysteresis through the actual measurement exclusive disjunction, can consider in advance, set.
Welding wire detection position identifying unit 27c compares, judges the shift position of the input block 27a input from the welding wire detection position and the switching position of memory cell 27b.Shift position on the represented direction of slip of the signal that receives from this welding wire detection position input block 27a and the switching position that is stored in the memory cell 27b are compared; When the shift position surpasses first switching position or the 3rd switching position; Being judged to be needs output to apply the high pressure switching signal that the pressure that makes driving cylinder mechanism 25 becomes this pressure of predefined high pressure; When the shift position surpassed second switching position and the 4th switching position, being judged to be needed output to change into the base pressure switching signal of predefined base pressure from high pressure.Just; This welding wire detection position identifying unit 27c judges that the position (two ends) that becomes winding layer rising one deck on the spool SP of welding wire W applies predefined high pressure to driving cylinder mechanism 25 and switches like this, and driving cylinder mechanism 25 is applied predefined base pressure in same winding layer the time.The result that this welding wire detection position identifying unit 27c judges exports to driving cylinder control signal output unit 27d.
Driving cylinder control signal output unit 27d is that output is in order to switch to driving cylinder mechanism 25 any one signal of base pressure or high pressure at this.The decision signal (base pressure decision signal or high pressure decision signal) that this driving cylinder control signal output unit 27d receives according to the identifying unit 27c from the welding wire detection position, to 25 outputs of driving cylinder mechanism make driving cylinder mechanism 25 switch to predefined base pressure switching signal, or make driving cylinder mechanism 25 switch to the switching signal of the high pressure of setting.
Driving cylinder control mechanism 27 possesses like formation discussed above; Therefore the control of carrying out is via the signal of input block 27a input in welding wire detection position from the member 40 that traverses; Utilize welding wire detection position identifying unit 27b to judge that driving cylinder mechanism 25 becomes base pressure or high pressure, according to the pressure that switches driving cylinder mechanism 25 from the switching signal of driving cylinder control signal output unit 27c.
Have, control mechanism 26 possesses in the future that the detection speed of the wire speed testing agency 30 of Self-adjusting dancer rools equipment 10 is presented at the display unit 28 in the display monitor 29 again.Display unit 28 inputs utilize numeral or chart to show on display monitor 29 so that the operator can discern from the speed signal that wire speed testing agency 30 sends.This display unit 28 also can show the signal that is input to control mechanism 26 to display monitor 29 outputs, so that the operator can discern it.Also have, except speed shows, can also apply to the actuating speed control (the maintenance welding wire is a constant speed) of spool SP, the various situation such as moving velocity control of the member that traverses from the signal of wire speed testing agency 30.
Next, the action about welding wire rewind 1 describes.
At first; Welding wire rewind 1 is extracted being provided with of equipment 2 out at welding wire winder BW is set on the platform 3; Be provided with simultaneously spool SP is set on the platform 55 at the spool of welding wire reeling equipment 50; Welding wire W is pulled out from winder BW, and tight pulley 11 and 12 coilings of mobile wheel to dance roller equipment 10 become a kind of state that welding wire W is engaged via this dance roller equipment 10 with spool SP.Also have, on each is taken turns, set in the situation of welding wire W, the setting of coiling direction be with this welding wire W that extracts out from winder BW be oriented the abdomen direction time, welding wire W according to the abdomen direction be wound up into tight pulley 11, move wheel 12, reel 31 also has spool SP.Consistent through the direction that makes welding wire W like this, can the reason that make welding wire W that plastic deformation take place be suppressed to irreducible minimum thus.
And; Welding wire rewind 1 is that the driven in synchronism welding wire is extracted the extraction rotary driving part 4 of equipment 2 and the coiling rotary driving part 56 of welding wire reeling equipment 50 out; Extract the winder BW extraction welding wire W of equipment 2 thus from welding wire out, utilize loose dancer rools machine 10 to make the tension force of welding wire W keep being wound on consistently on the spool SP.
Welding wire W is during via dance roller equipment 10; Take turns this mode of second wheel 11a of 12a, tight pulley 11 according to take turns 11a from first of tight pulley 11 to first that moves wheel 12 to second the wheel 12a that moves wheel 12; Via tight pulley 11 respectively take turns 11a and move wheel 12 respectively take turns 12a, be wound up into welding wire reeling equipment 50 sides from reel.
Utilize dance roller equipment 10 to keep welding wire W when to keep tension force be constant state; Detect the position of moving wheel 12 with sensor 19; According to the detection position of the mobile wheel of its detection, utilize the rotative speed control mechanism 26A of control mechanism 26 to control to extracting rotary driving part 4 out.
Promptly; Rotative speed control mechanism 26A utilizes identifying unit 26c that the mobile wheel 12 that is stored in the desired location among the memory cell 26b and detect with sensor 19 is compared; When the detection position of the mobile wheel 12 that judge to detect is in than desired location near the position of tight pulley 11 sides; Transmit signal from output unit 26d to extracting rotary driving part 4 out, the control of carrying out is to slow down from present speed.In addition; Rotative speed control mechanism 26A utilizes identifying unit 26c that the detection position of the mobile wheel 12 that is stored in the desired location among the memory cell 26b and detects with sensor 19 is compared; When the detection position of judge moving wheel 12 is in than desired location away from the position of tight pulley 11 sides; Transmit signal from output unit 26d to extracting rotary driving part 4 out, the control of carrying out is to quicken from present speed.
Thereby; Through the rotative speed of extracting rotary driving part 4 out is slowed down; Thus; Rotation be supported on freely on the bracing frame 17 mobile wheel 12 with set up the state that member 23 engage under, mobile wheel 16,16,16,16 rotated and move along moving guide rail 15,15 to the direction of leaving gradually from tight pulley 11 sides.Through the rotative speed of extracting rotary driving part 4 out is quickened, thus, move wheel 12 with set up the state that member 23 engage under, to tight pulley 11 sides gradually near direction mobile wheel 16,16,16,16 rotated and move along moving guide rail 15,15.
Like this, detect the position of moving wheel with sensor 19 all the time, control its to suitable desired location near, therefore, applied constant tension force equably via the welding wire W of dance roller equipment 10.
And, be wound onto on the set spool SP of welding wire reeling equipment 50 via the welding wire W of dance roller equipment 10.Welding wire reeling equipment 50 set spool SP can one section one section (in layer) arrange coiling welding wire W through the action of the member 40 that traverses.Also have, in the welding wire rewind, the control that this rotative speed control mechanism 26A carries out is the adjustment operation.
Also have; Driving cylinder control mechanism 27 is according to the signal that sends from the sensor (not having diagram) that is arranged on the member 40 that traverses; The pressure of controlling and driving cylinder mechanism 25, thus, can keeping more uniformly, tension force involves in the row coiling to the arrangement that is wound on the welding wire W on the spool SP.Promptly as shown in Figure 4, in welding wire reeling equipment 50, traverse member 40 from the end of spool SP to the other end or from the other end to laterally the slide position of welding wire W of an end.And shown in Fig. 4 (a), when spool SP coiling ground floor, driving cylinder mechanism 25 sets up member 23 with base pressure (normal pressure) extruding, keeps the position of moving wheel 12.At this moment; The signal input block 27a input that welding wire W is divided the shift position that timing representes to slide from the member 40 that traverses from the welding wire detection position; And judge by welding wire detection position identifying unit 27c; According to its result, be situated between by the signal from driving cylinder control signal output unit 27d output, 25 one-tenth base pressures of driving cylinder control mechanism 27 controlling and driving cylinder mechanisms.
And; Shown in Fig. 4 (a) and (b); To compare from the signal of shift position on the expression direction of slip of the member 40 that traverses and the switching position (first switching position) of memory cell 27b; When judging that it surpasses first switching position, just at welding wire W when spool other end W1 arrives the position of W2, driving cylinder mechanism 25 is switched.Promptly; Welding wire detection position identifying unit 27c compares with the switching position (first switching position) that is stored in memory cell 27b the shift position of the input block 27a input from the welding wire detection position; When judging that the shift position surpasses first switching position; The pressure that is judged to be driving cylinder mechanism 25 switches to high-voltage timing, the pressure of driving cylinder mechanism 25 is switched to the signal of high pressure from driving cylinder control signal output unit 27d output from base pressure.Also have, in driving cylinder control mechanism 27, when according to the pressure of driving cylinder control signal output unit 27d controlling and driving cylinder mechanism 25, need to consider output signal, the hysteresis that pressure is changed.Thereby; Driving cylinder control mechanism 27 preferably calculates the slide block moving velocity of the member 40 that traverses and the relation of switching position in advance; In being wound up into the layer of spool SP; Pressure to which shift position could in time switch driving cylinder mechanism 25 in the position from W1 to W2 is investigated, and sets switching position.The setting of switching position preferably first switching position to the, four switching positions will preestablish all.
If driving cylinder mechanism 25 switches to high pressure with its pressure from base pressure, then can on the direction that makes the pressure moment enhancing of setting up member 23 that promotes engaging, apply power.At this moment, move wheel 12 and be applied in power in the direction of leaving from tight pulley, moment is improved the tension force of the welding wire W that is wound on the spool SP thus.
When being wound on welding wire W on the spool SP, in the moment of number of plies increase one deck, the spool rotative speed has the tendency of deceleration.That is to say that the rotative speed of welding wire rewind 1 adjustment spool SP is so that wire speed is constant, thereby in the position of welding wire W increase one deck, the spool rotative speed slows down.Therefore, for the moment of slowing down at spool SP, the feeding of welding wire W can not lag behind and can not take place and loosely reel, and the driving cylinder mechanism 25 on the dance roller equipment 10 is switched to high pressure, is pressed into welding wire W by force, suppresses the vibration of welding wire W.
Then, as Fig. 4 (b) (c) shown in, welding wire W relies on the position of member 40 from W2 toward W3 of traversing laterally to slide when moving, and carries out driving cylinder mechanism 25 is switched to from high pressure the action of base pressure.At this moment, import the shift position on the direction of slip from the member 40 that traverses to welding wire detection position input block 27a, and input block 27a transmits to welding wire detection position identifying unit 27c from its welding wire detection position.
So; Utilize welding wire detection position identifying unit 27c; Switching position (second switching position) and shift position to memory cell 27b compare; When the shift position surpassed switching position (second switching position), judgement was the timing that the pressure of driving cylinder mechanism 25 is switched to base pressure, the pressure of driving cylinder mechanism 25 was switched to the signal of base pressure from driving cylinder control signal output unit 27d output from high pressure.Thereby, getting back to the state that promotes with base pressure during to the position of W3 from the position of W2 with the member 23 that sets up of driving cylinder mechanism 25 pushing.As shown in Figure 4 equally in the welding wire rewind 1, also carry out comparison, the judgement of shift position and switching position (the 3rd switching position and the 4th switching position) in the left side of spool SP, carry out the pressure adjustment same with the right side.
Like this shown in Fig. 4 (a)～(d); Welding wire rewind 1; Utilize the driving cylinder control mechanism 27 of control mechanism 26 to carry out the control of driving cylinder mechanism 25, the position that can change at the winding layer of spool SP both end sides thus suppresses the lax reason of welding wire W; Can go up coiling welding wire W toward spool SP with uniform tension force, recoil effect.
Also have, even if make the pressure instantaneous variation of utilizing 25 pushings of driving cylinder mechanism to set up member 23 like this, the position of moving wheel 12 also can change hardly.
In addition, in the welding wire rewind 1, if will realize improving through the speed of change welding wire W, then along with the change of speed, the welding wire W on the dance roller equipment 10 vibrates.Thereby; In welding wire rewind 1 at the two ends of spool SP when winding layer changes; Pressure to utilizing driving cylinder mechanism 25 to impose on welding wire is adjusted, so that the tension force that imposes on welding wire W is controlled, thus; Can make the not change of speed of welding wire W, the vibration of inhibition welding wire W, can welding wire W arrangement be wound on the spool SP with uniform tension force.
If the control mechanism 26 of welding wire rewind 1 possesses rotative speed control mechanism 26A; Then basically; The tension force that can keep welding wire W is for recoil welding wire W on spool SP from winder BW consistently; And, then can keep the tension force of welding wire to reel more reliably for going up toward spool SP consistently through making control mechanism 26 possess driving cylinder control mechanism 27.Thereby welding wire W can guarantee the welding operation of rectilinear propagation.
Also have; Detection position about basis in the welding wire rewind 1 and the mobile wheel that detects with sensor 19 changes corresponding linear output signal; The rotative speed of rotative speed control mechanism 26A slowed down or quicken control to be illustrated, and but, also can adopt following formation.
That is, rotative speed control mechanism 26A utilizes identifying unit 26c whether to form base pressure or is higher than the judgement of the high pressure of base pressure.That is to say that whether identifying unit 26c surpasses position (threshold value) scope that is provided with that is stored in memory cell 26b to the detection position that inputs to input block 26a compares, judges, and output forms the signal that base pressure still forms high pressure.
And when judging that with identifying unit 26c the detection position surpasses desired location, output unit 26d is the speed of extracting rotary driving part 4 out to be slowed down be the slow pre-set velocity of datum velocity than setting to the signal of extraction rotary driving part 4 outputs.In addition, when judge with identifying unit 26c the detection position surpass desired location, just in the scope in threshold value the time, output unit 26d is to extracting the signal that rotary driving part 4 outputs become datum velocity out.
Like this; Utilize drive controlling that rotative speed control mechanism 26A judge to extract rotary driving part 4 out whether in the scope of threshold value; Control is extracted rotary driving part 4 out and is formed datum velocity and the geard-down speed slower than its datum velocity, and the tension force that can remain the welding wire W that is produced by tight pulley 11 and mobile wheel 12 thus is constant.
Also have, when the recoil work of the welding wire W when the welding wire retension job finishes, when welding wire cuts off stopped, the Clamping force of 9 couples of welding wire W of killer was so long as get final product more than the Clamping force that the slip when allowing the pleat phenomenon of the welding wire W that eliminates operation is gone.
In addition, in welding wire rewind 1, the mode of recoiling flux-cored wire W is illustrated, but the mode of other welding wires such as solid wire that can be applied to equally to reel.
Have, the signal that position 27c receives is judged so long as can represent the signal of welding wire W position in the welding wire detection position again, can be via after state the signal of the moving velocity of the welding wire W that the member 40 that traverses distributes.The formation that welding wire detection position identifying unit 27c adopts when the signal of expression welding wire W moving velocity is judged is; The data storage that to represent moving velocity in advance compares the moving velocity signal of its canned data and input, judge in memory device.
