Then, describe adjusting roller 21 and the mechanism that wire rod emits in the machine 20 around the winding footpath of the wire rod 3 that is hung on roller 21.
In addition, below, the winding shape of so-called wire rod 3 is meant the annular shape that is wound in the wire rod 3 of rolling up core 11, roller 21, in addition, the winding of so-called wire rod 3 footpath is the internal diameter of finger ring.
It is that the roller footpath is along rotation direction continually varying taper to the size in the cross section of the similar and roller 21 of cross sectional shape of volume core 11 that roller 21 forms cross sectional shape.
The position around hanging wire material 3 of roller 21 can change by with roller footpath adjusting mechanism 50 roller 21 is moved along the rotation direction.Specifically, roller 21 forms along with becoming gradually greatly towards rotation rear sectional area, therefore, moves to rotation the place ahead by making roller 21, and the roller around the position of hanging wire material 3 of roller 21 directly becomes greatly, directly becomes big around the winding of the wire rod of hanging 3.
In addition, the cross sectional shape of roller 21 is similar to the cross sectional shape of volume core 11, thus even roller 21 is moved along the rotation direction, roller 21 around the cross sectional shape at the position of hanging wire material 3 and to roll up the cross sectional shape of core 11 also always identical.
By roller 21 is moved along the rotation direction, can make around the winding shape and the winding footpath of the wire rod 3 that is hung on roller 21 identical with the winding shape and the winding footpath of the wire rod 3 that is wound in volume core 11.
Roller footpath adjusting mechanism 50 comprises: mounting emit motor 25 electronic board 52, be configured on the pallet 19, the guide rail 53 that extends abreast with the rotation of emitting motor 25, combine with electronic board 52, and the driven member 51 that moves freely along guide rail 53, with driven member 51 threaded engagement, and the ball-screw 54 that extends abreast with the rotation of emitting motor 25, the roller travel motor 55 that drives ball-screw 54 rotations.
By driven roller travel motor 55, electronic board 52 moves along guide rail 53, so the emit motor 25 of mounting on electronic board 52 moves along this rotation direction.By driven roller travel motor 55 in this wise, roller 21 is moved along the rotation direction, roller footpath adjusting mechanism 50 can change the roller footpath around the position of hanging wire material 3 of roller 21.
In addition, roller footpath adjusting mechanism 50 also comprises and makes roller 21 be used to prevent the guiding mechanism (omitting diagram) that moves together around the wire rod 3 that is hung on roller 21 and roller 21 when the rotation direction moves.By using guiding mechanism, wire rod 3 is directed and route by regulation, thus roller 21 when the rotation direction moves, around the winding footpath of the wire rod 3 that is hung on roller 21 also along with this gliding smoothing ground change.
Be provided with the speed detector 60 that the speed that supplies to the wire rod 3 of rolling up core 11 from roller 21 is detected between the tension roller 33 of the rotation leading section of tension arm 32 and the volume core 11.
Speed detector 60 comprises the encoder 62 around the anglec of rotation of the pulley 61 of hanging wire material 3 and detection pulley 61.The anglec of rotation by encoder 62 detected pulleys 61 is imported in the controller 70, and controller 70 supplies to the speed of the wire rod 3 of volume core 11 based on this anglec of rotation computing that is transfused to.
At this, on volume core 11, repeat wound wire 3, thereby twine the number of plies when increasing, elongated around the length of the wire rod 3 in volume 11 1 weeks of core, so the speed of wire rod 3 rises.In controller 70, store the 1st reflection of the speed of having stipulated wire rod 3 and the relation of twining the number of plies, this reflection of controller 70 usefulness is judged the present winding number of plies of wire rod 3 according to the speed of the wire rod 3 that calculates, and is wrapped in present winding footpath on the volume core 11 according to the winding number of plies computing of this judgement.
In controller 70, store the 2nd reflection of having stipulated roller 21 around the relation in the roller footpath at the position of hanging wire material 3 along the amount of movement of rotation direction and roller 21.The coning angle of this reflection by roller 21 waits to be stipulated.The amount of movement along the rotation direction of this reflection control roll 21 of controller 70 usefulness makes that the winding around the roller footpath at the position of hanging wire material 3 and the volume core 11 that calculates of roller 21 is directly identical.
Then, the coiling action by the Winder 100 of controller 70 control is described.
(1) preparation before the coiling
The wire rod 3 that takes out from wire rod supply source 2 around hanging roller after 21 1 weeks, around being hung on pulley 16, tension roller 33 and the pulley 61, is bundled in the leading section of wire rod 3 by mechanical hand (omitting diagram) on the terminal of volume core 11 (omitting diagram).
In addition, adjust the initial position of the rotation direction of rollers 21, make that the cross-sectional sizes around the position of hanging wire material 3 of roller 21 is identical with the cross-sectional sizes of the stem portion 11a that rolls up core 11 by roller footpath adjusting mechanism 50.
(2) winding process
Identical with mutual rotating speed, and the identical mode driven in synchronism winding motors of mutual rotatable phase 13 and emit motor 25 rotations.So, by driven in synchronism winding motors 13 with emit motor 25 rotations, the position of rotation of volume core 11 and roller 21 remains on identical position.
By driving winding motors 13 and emit motor 25 rotations, the wire rod 3 of emitting successively from roller 21 fitly is wrapped in the periphery of the stem portion 11a of volume core 11.After the 1st layer the winding of stem portion 11a finished, carry out the 2nd layer winding, after the 2nd layer winding is finished, carry out the 3rd layer winding in the periphery of the 2nd layer wire rod 3 in the periphery of the 1st layer wire rod 3.So, be wrapped on the stem portion 11a to wire rod 3 multilayers, the winding footpath of the wire rod 3 on stem portion 11a that winds the line is along with the increase change of the number of plies is big.
Computing is directly carried out in winding with 70 pairs of wire rods 3 of controller.Specifically, according to judging the present winding number of plies, computing is directly carried out in the present winding that is wound on the volume core 11 according to this winding number of plies that is determined by the speed and above-mentioned the 1st reflection of speed detector 60 detected wire rods 3.
Then, controller 70 uses the amount of movement that advances along the rotation direction of above-mentioned the 2nd reflection control roll 21, makes when the winding of the wire rod 3 that is wound in stem portion 11a directly becomes big, and its roller around the position of hanging wire material 3 that twines footpath and roller 21 is directly identical.
So, the roller footpath around the position of hanging wire material 3 of roller 21 changes in the mode identical with the winding footpath of the wire rod 3 that is wound in stem portion 11a, and the cross sectional shape of roller 21 is similar with the cross sectional shape of rolling up core 11, so identical with the winding shape with the winding footpath of the wire rod 3 that is wound in stem portion 11a around the winding footpath and the winding shape of the wire rod 3 that is hung on roller 21.
In coiling, control like this so that identical with the winding shape with the winding shape with the winding footpath of the wire rod 3 that is wound in stem portion 11a around the winding footpath of the wire rod 3 that is hung on roller 21, and to winding motors 13 with emit motor 25 and carry out Synchronization Control, make that the mutual rotating speed of the two rotation is identical, and mutual rotatable phase is identical.Therefore, when the speed of wire rod 3 was changed, the speed of the wire rod 3 of emitting successively from roller 21 also changed in the same manner with this velocity variations.For this reason, the change of the tension force of the wire rod 3 between core 11 and the roller 21 can be suppressed to roll up, the deflection angle of tension arm 32 can be suppressed.
About this point, with reference to Fig. 2, explanation in further detail.Fig. 2 A is the cutaway view in the cross section of expression volume core 11, and Fig. 2 B is the performance plot of situation of the velocity variations of expression wire rod 3.
Shown in Fig. 2 A, in the cross section of the volume core 11 that is rectangle in the cross section, will length be made as a, the length from pivot O to minor face 11B is made as b, the distance from pivot O to bight 11C is made as c from pivot O to long limit 11A.At this moment, when the angular velocity of rotation of volume core 11 is retained as steady state value ω, shown in Fig. 2 B, be wound in volume core 11 wire rod 3 speed (longitudinal axis) with respect to the anglec of rotation (transverse axis) of volume core 11 produce a ω, c ω, b ω, c ω, a ω ... flex point ground change.
At this, the cross sectional shape of roller 21 is under the situation of circle as in the past, during to volume core 11 wound wires 3, because periodically deflection of tension arm 32, so the angular velocity of rotation of modified line electric motor with speed 17 and the speed of the wire rod 3 shown in Fig. 2 B need be controlled accordingly.Therefore, the Tension Control that is difficult to supply to the wire rod 3 of volume core 11 is constant, when using thin wire rod 3, has because the tension change of wire rod 3 causes the possibility of broken string.
To this, in the present embodiment, so that around the winding of the wire rod 3 that is hung on roller 21 footpath and the winding footpath and the identical mode of winding shape of twining shape and the wire rod 3 that is wound in stem portion 11a control, so by the angular velocity of rotation of roller 21 is kept identical steady state value ω with volume core 11, the speed of the wire rod 3 of emitting successively from roller 21 also changes shown in Fig. 2 B in the same manner with the speed that is wound in the wire rod 3 of rolling up core 11.Therefore, the change of the tension force of the wire rod 3 between core 11 and the roller 21 can be suppressed to roll up, the periodic deflection of tension arm 32 can be suppressed.Thus, the tension force that supplies to the wire rod 3 of volume core 11 can be kept constant accurately, can make high-quality coil.
In addition, as mentioned above, directly suppress to roll up the change of the tension force of the wire rod 3 between core 11 and the roller 21 by the roller that changes roller 21 around the position of hanging wire material 3, yet because roller directly changes the tension force that the delay etc. of control causes the wire rod 3 between volume core 11 and the roller 21 temporarily change takes place sometimes, tension arm 32 deflects.At this moment,, change the linear velocity of the wire rod 3 of emitting successively, with Tension Control (adjusting) the one-tenth desired value of wire rod 3 from pulley 16 by 17 work of modified line electric motor with speed.So, modified line electric motor with speed 17 directly changes the mode of controlling with help roll footpath adjusting mechanism 50 pair rollers and carries out work.
(3) operation after the coiling
The number of plies of wishing is cut off wire rod 3 by mechanical hand after twining and finishing, and the terminal part of wire rod 3 is bundled on the terminal (omitting diagram) of volume core 11.Then, take off volume core 11, new volume core 11 is installed on the main shaft 12 from main shaft 12.Make coil as described above.
In addition, in the present embodiment, roller 21 is formed bulk, but be not limited thereto, also the roller 21 around hanging wire material 3 can be formed the frame shape, change the size of frame by adjuster.That is to say, reach requirement, also can change the shape and the size around the position of hanging wire material 3 of roller 21 in order to make around the winding shape of the wire rod 3 that is hung on roller 21 and to twine the footpath.
Present embodiment shown in more than adopting reaches effect shown below.
When even pair cross-section is shaped as volume core 11 wound wires 3 of different-diameter, also can makes around winding shape and the winding footpath mode identical of the wire rod 3 that is hung on roller 21 and control with winding shape that is wound in the wire rod 3 of rolling up core 11 and winding footpath.Therefore, the tension force of the wire rod 3 that is wound in volume core 11 can be controlled accurately, the change of tension force can be suppressed.Thus, can improve the quality of the different-diameter coil of made.
In addition, roller 21 forms the similar and roller of the cross sectional shape footpath of cross sectional shape and volume core 11 along rotation direction continually varying taper.Therefore, by using roller footpath adjusting mechanism 50 to make roller 21 move and the roller around the position of hanging wire material 3 of roller 21 directly changed over wish the roller footpath along the rotation direction, even and roller 21 is moved along the rotation direction, the cross sectional shape around the position of hanging wire material 3 of roller 21 is always identical with the cross sectional shape of volume core 11.So, similar by the shape that makes roller 21 to the cross sectional shape of core 11, and form taper along the rotation direction, thereby only depend on roller 21 is moved along the rotation direction, just can make around the winding shape and the winding footpath of the wire rod 3 that is hung on roller 21 identical with the winding shape and the winding footpath of the wire rod 3 that is wound in volume core 11.
(the 2nd execution mode)
With reference to Fig. 3, the Winder 200 of the 2nd execution mode of the present invention is described.Fig. 3 is the stereogram of expression Winder 200.
Winder Winder 200 and above-mentioned the 1st execution mode 100 identical structures to present embodiment mark identical Reference numeral, omit explanation.Below, be that the center describes with difference with Winder 100.
The partial structurtes that difference with Winder 100 above-mentioned the 1st execution mode Winder 200 is a tensioning apparatus 15 are different.
In the tensioning apparatus 15 of the Winder 100 of above-mentioned the 1st execution mode, by the rotating speed of control modified line electric motor with speed 17, change the linear velocity of the wire rod 3 of emitting successively from pulley 16, regulate the tension force that supplies to the wire rod 3 of volume core 11 from roller 21.
Relative therewith, the tensioning apparatus 150 of Winder 200 does not comprise pulley 16 and modified line electric motor with speed 17, but regulates the tension force that supplies to the wire rod 3 of volume core 11 from roller 21 by the rotation speed change of emitting motor 25.
In Winder 200, identical with the 1st execution mode, directly suppress to roll up the change of the tension force of the wire rod 3 between core 11 and the roller 21 by the roller that changes roller 21 around the position of hanging wire material 3.But,, when tension arm 32 deflects, control the tension force of (adjusting) wire rod 3 by emitting motor 25 work because roller directly changes the tension force change that the delay etc. of control causes the wire rod 3 between volume core 11 and the roller 21.So, in Winder 200, emit motor 25 and directly change the mode of controlling with help roll footpath adjusting mechanism 50 pair rollers and carry out work.
Emit motor 25 when directly changing the mode of controlling and carry out work with help roll footpath adjusting mechanism 50 pair rollers, the increase and decrease of the rotating speed by emitting motor 25 departs from the rotatable phase of emitting motor 25 and winding motors 13.But this phase deviation is temporary, if the control stabilization that roller footpath adjusting mechanism 50 pair rollers directly change, it is identical once more with the rotating speed and the rotatable phase of winding motors 13 then to emit motor 25.
Present embodiment shown in more than adopting reaches effect shown below.
