Description
Technical field
The present invention relates to a kind of Winder of wire rod, will be wound in from the wire rod that derive on the top of line mouth on the outstanding magnetic pole that forms of the radial direction of stator.
Background technology
In the past, the stator of internal gear type motor is wire rod is wrapped on the interior week of stator core side-prominent a plurality of magnetic poles and forms, wherein stator core is formed by a plurality of endless member laminations, and the stator of external-rotor motor is that wire rod is wrapped in from the outer circumferential side of this stator core with on radial outstanding a plurality of magnetic poles and form.In the past, be by making the line mouth that is installed on the main shaft along with the rotation of main shaft for example revolves round the sun to carry out with circular trace around each magnetic pole in each the magnetic pole coiling to this stator core.By the coiling of such king post system, can make the winding operation high speed.
But, in the coiling of such king post system, interval to a certain degree need to be set between the top of the line mouth of deriving end as wire rod and magnetic pole, the problem that can not critically control the position on line mouth top when therefore having coiling.Therefore exist for example can't make the line mouth around the revolution of magnetic pole with critically cooperate to the axial conveying of magnetic pole, and in coiling, occur unrest around problem.And in the situation of the stator core of the type that has protuberance between magnetic pole and the magnetic pole, also there is the such problem of track of this protuberance interfering line mouth.
In order to address the above problem, the applicant has proposed to have and has made the line mouth respectively at the Winder (for example, with reference to patent documentation 1) of three mobile table transferring mechanisms of the direction of three axles.Namely, this Winder supports left/right movement device by moving forward and backward mechanism, left/right movement device can be moved forward and backward, and by this left/right movement device reciprocating mechanism is supported, make the reciprocating mechanism can move left and right, and then by this reciprocating mechanism traveling table is supported, traveling table can be moved up and down, and the line mouth is installed on this traveling table.Be the combination by the action of above-mentioned three table transferring mechanisms in this Winder, make the traveling table that wired mouth is installed mobile at three-dimensional, thereby can critically control wire rod derivation end that is the apical position of this line mouth.Do not occur thus disorderly to wind the line around ground, therefore can expect to improve by the stator that the high neat coiling of the occupation efficiency of wire rod forms the characteristic of motor.
Patent documentation 1: Japanese kokai publication hei 10-271774 communique
But, in above-mentioned Winder in the past, make the line mouth respectively in the mobile travel mechanism of the direction of three axles by with all around, each travel mechanism carries out successively lamination and consists of up and down, therefore move forward and backward mechanism left/right movement device and reciprocating mechanism are moved with the line mouth, left/right movement device must make reciprocating mechanism and line mouth mobile together in addition.Like this, the part mobile with the line mouth is larger, thus the line mouth based on the front and back action that moves forward and backward mechanism, line mouth based on left/right movement device about action can't realize high speed, its result has hindered the high speed of winding operation.
In addition, owing to the reciprocating mechanism in the above-mentioned Winder in the past uses ball-screw, therefore use servomotor to make this lead screw shaft rotation, the traveling table that wired mouth is installed is moved.For this ball-screw, when servomotor made this lead screw shaft rotate one time, the amount that the line mouth moves up and down was equivalent to be formed on the spacing of helicla flute on long axis direction on this lead screw shaft.And when the magnetic pole of stator winds the line, usually must make the line mouth move the several times of this helicla flute spacing to decades of times, therefore in order to make this line mouth come and go mobile the coiling, servomotor must after making this lead screw shaft forward arrive for several times tens of times, make its counter-rotating for several times to tens of times again.Therefore have in the above-mentioned Winder in the past of ball-screw in use, in that the line mouth is moved in the situation about winding the line with speed faster, need to make lead screw shaft with High Rotation Speed by servomotor, and this lead screw shaft is carried out anxious acceleration and deceleration.Therefore in the Winder in the past that uses ball-screw to wind the line, as the drive source that makes this lead screw shaft rotation, need the servomotor of so-called high torque (HT) and high response.Because such servomotor price is very expensive and maximization, therefore when pursuing high-speed winding, then can produce the problem that unit price rises and this device maximizes of this device.
Summary of the invention
The present invention is conceived to the problems referred to above make, purpose be to provide a kind of can be on the magnetic pole of stator the Winder of high accuracy and the wire rod that twines at high speed.
The present invention is the improvement that will be wrapped in from the wire rod of line mouth derivation the Winder on the magnetic pole of stator.
Its constitutive characteristic is, has to make the line mouth in the mobile line mouth travel mechanism of the direction vertical with the axle of magnetic pole, and this line mouth travel mechanism possesses: pedestal; Traveling table, it to be can being arranged on the pedestal in the mobile mode of the direction vertical with the axle center of magnetic pole, and fixes wired mouth thereon; Drive source, it constitutes and is arranged on the pedestal and can makes rotating parts rotation; Connecting member, the one end is supported on the position of the pivot that departs from rotating parts by axle, and the other end is supported on traveling table by axle.
Preferably, the Winder of this wire rod possesses the stator core actuating mechanism, this stator core actuating mechanism makes stator core action so that magnetic pole shakes, and line mouth travel mechanism constitutes: make the line mouth from the direction of the axle approximate vertical of magnetic pole on and with magnetic pole to shake the different direction of direction mobile.
In the Winder of wire rod of the present invention, it is mobile by line mouth travel mechanism the line mouth to be come and gone, and by other travel mechanism make the line mouth with the direction of the axle approximate vertical of magnetic pole on and mobile in the direction vertical with the round moving direction of this line mouth travel mechanism, by the combination of these actions, make line mouth rotary moving around magnetic pole.The wire rod of deriving from the line mouth can be wrapped on the magnetic pole of stator thus.Namely, words take the magnetic pole that is wound with wire rod as benchmark, be rotated movement at its circumferential wire mouth with the runway shape, become the movement of line mouth of the straight line portion of this runway, rectilinear motion for the slit of line mouth between magnetic pole and magnetic pole, the wire rod that can reduce thus the line mouth is derived the gap that produces between end and the magnetic pole, avoid in coiling, occuring disorderly around situation.
In addition, round movement by the line mouth of line mouth travel mechanism, by drive source the rotating parts rotation is carried out, when making the rotating parts rotation, depart from an end of the connecting member that its pivot supported by axle and draw out circular motion, the traveling table that makes axle support this connecting member other end comes and goes mobile with the line mouth.Therefore when rotating parts rotates one time, the line mouth carries out back and forth movement one time, the amount of a back and forth movement equals the value of the twice of the amount that departs from from the pivot of rotating parts, drive source just can make line mouth back and forth movement and the corresponding number of times of this number of revolutions only by making rotating parts to same direction rotation.Therefore need not that in the past the servomotor that makes the lead screw shaft rotation in the ball-screw must carry out from beginning anxious acceleration and deceleration at a high speed, thereby can make with comparalive ease the coiling high speed.In addition, need not to begin to carry out the high torque (HT) of anxious acceleration and deceleration, the servomotor of high response from high speed, so the unit price of Winder can not rise yet in the past yet.
In addition, as making the line mouth in vertical another the mobile travel mechanism of direction of the round moving direction that carries out with this line mouth travel mechanism, make the stator core action so that the stator core actuating mechanism that magnetic pole shakes as long as possess, just can be in this stator core actuating mechanism, wind the line by stator core is rotated and reverse with following angle, described angle is equivalent to as the magnetic pole of coiling object and the magnetic pole angulation adjacent with this magnetic pole.At this, because less as magnetic pole and the magnetic pole angulation adjacent with this magnetic pole of coiling object, the shaking of magnetic pole when therefore winding the line can promptly be carried out, and can make effectively the threading speed high speed thus.

Bar-shaped core 18a is because its lower end is installed on the rotating shaft 19a that shakes with servomotor 19, therefore when the rotating shaft 19a of servomotor 19 rotation, bar-shaped core 18a rotates with this rotating shaft 19a, by the stator core 13 of bar-shaped core 18a and pressing component 18b clamping, centered by the central shaft of the supporting member 18 that consisted of by bar-shaped core 18a and pressing component 18b, rotate.And stator core 13 constitutes: be positioned in the upper ora terminalis of bar-shaped core 18a, its center is consistent with the central shaft of supporting member 18, and the magnetic pole 13b around the stator core 13 constitutes: the rotation by stator core 13 can be shaken.Therefore, this shakes with servomotor 19 and constitutes: play a role as the stator core actuating mechanism that makes stator core 13 actions, so that magnetic pole 13b shakes.And the mounting panel 21 above its Lift Part 22 arranges the lifting cylinder 24 that makes this Lift Part 22 and pressing component 18b one lifting.
In addition, setting makes line mouth 11 in the mobile line mouth travel mechanism 30 of the direction vertical with the axle of magnetic pole 13b in this Winder 10.This line mouth travel mechanism 30 has: pedestal 31, and it is directly fixed on board 14 in vertically extending mode; Traveling table 32, it is arranged on facing on the face of stator core 13 of this pedestal 31 in the mode that can move in vertical direction; Drive source 33, it constitutes the top that is arranged on pedestal 31, can make rotating parts 34 rotations; Connecting member 36, it links above-mentioned rotating parts 34 and traveling table 32.The face in the face of stator core 13 at pedestal 31 is provided with linear motion guide rail 37, and this linear motion guide rail 37 vertically extends, and traveling table 32 is being arranged on along the mode that Z-direction moves on this guide rail 37.In addition, the drive source of present embodiment is lifting with servomotor 33, and axle is supported on the extended line of rotating shaft 33a of servomotor 33 and above traveling table 32 rotating parts 34 via shaft supporting part 38.The central shaft 34a of rotating parts 34 and lifting are linked by Hooks coupling universal coupling 39 with the rotating shaft 33a of servomotor 33, and constitute by the rotation of lifting with the rotating shaft 33a of servomotor 33, and directly make rotating parts 34 rotations.On the other hand, an end of connecting member 36 is supported on the position of the pivot that departs from rotating parts 34 by axle, and the other end is supported on traveling table 32 by axle, and this traveling table 32 is installed in the below of rotating parts 34 in the mode that can move up and down.And, prolonging platform 41 and extend and be fixed on this traveling table 32 along Y direction, line mouth 11 extends and is fixed on the jag of this prolongation platform 41 and is the part that is positioned at the X-direction of stator core 13 along X-direction.
Below, the winding operation that uses such wire rod coiling device is described.
In the winding operation that uses this Winder 10, at first, by supporting member 18 supporting stator cores 13.When carrying out this supporting, fore-and-aft direction drive division 17 drives its fore-and-aft direction servomotor 17c, makes fore-and-aft direction rotating shaft 17b rotation, shown in the solid arrow of Fig. 1, make thus fore-and-aft direction moving-member 17d with workbench 16 away from pedestal 31.Under this state, the lifting that is arranged at mounting panel 21 is entered with the bar 24a of cylinder 24 and Lift Part 22 is risen, make such rise of pressing component 18b shown in single-point line arrow that is installed on this Lift Part 22, thereby thereunder and between the bar-shaped core 18a form the space.And stator core 13 flatly is positioned in the upper limb of bar-shaped core 18a via this space.Then, make lifting outstanding with the bar 24a of cylinder 24, make such descend of Lift Part 22 shown in the double dot dash line arrow, and by the pressing component 18b that descends with this Lift Part 22, as shown in Figure 1, the stator core 13 to the upper limb that is positioned in bar-shaped core 18a is pressed from the top.
Then, fore-and-aft direction drive division 17 drives its fore-and-aft direction servomotor 17c, makes fore-and-aft direction rotating shaft 17b to opposite spin, makes fore-and-aft direction moving-member 17d with workbench 16 close pedestal 31 shown in the dotted arrow of Fig. 1.Then, when the actual coiling of beginning, fore-and-aft direction drive division 17 by stator core 13 is moved along X-direction, make line mouth 11 along line mouth travel mechanism 30 that Z-direction moves and as making stator core 13 actions so that shaking with servomotor 19 of playing a role of the stator core actuating mechanism that magnetic pole 13b shakes, make line mouth 11 mobile at three-dimensional with respect to stator core 13, and the end of the wire rod 12 that will derive from the top of this line mouth 11 in advance is fixed around anchor line (string) pin or thread-clamping device.Then, carry out actual coiling, yet when this actual coiling, by line mouth travel mechanism 30 line mouth 11 is come and gone along Z-direction mobile, and by shaking positive rotation and the despining of alternately carrying out stator core 13 with servomotor 19, so that the magnetic pole 13b that is wound the line shakes.By the combination of these actions, make line mouth 11 along the cross sectional shape of magnetic pole 13b around this magnetic pole 13b with runway shape rotary moving.
Rotary moving to this runway shape specifically describes, as shown in Figure 4 and Figure 5, the round movement that line mouth 11 carries out based on line mouth travel mechanism 30, be on the top that makes line mouth 11, namely deriving as wire rod of minor diameter part 11b carried out under the state of the slit 13c that forms between magnetic pole 13b that the top of end enters at stator core 13 and the magnetic pole 13b.And as shown in Figure 6, be positioned at when the top of line mouth 11 in the situation of the slit 13c that the magnetic pole 13b that is carried out coiling and the magnetic pole 13b adjacent with the side of this magnetic pole 13b clip, do not carry out by shaking with the shaking of the magnetic pole 13b of servomotor 19, and this line mouth 11 is descended.Then, when extract from this slit 13c on the top of this line mouth 11, beginning magnetic pole 13b shakes, and between the magnetic pole 13b that is winding the line on the top of this line mouth 11 and the magnetic pole 13b adjacent with the side of this magnetic pole 13b adjacent slit 13c below stage stop it and shake.That is, begin the shaking of magnetic pole 13b in the moment of extracting from initial slit 13c downwards, and the top of the line mouth 11 that rises the turning back a conversion direction of lower end enters next adjacent slit 13c and stopped in the past it and shake.When line mouth 11 tops of observing this moment centered by magnetic pole 13b mobile, the arc track below Fig. 6 is drawn out on the top of this line mouth 11.
And, the top of online mouth 11 from the adjacent slit 13c that is clipped by this magnetic pole 13b and another magnetic pole 13b rise during, only make these line mouth 11 risings and this magnetic pole 13b is shaken, when extract upward from this adjacent slit 13c on the top of this line mouth 11, magnetic pole 13b is shaken to opposite direction, and the stage above the top of this line mouth 11 is positioned at initial slit 13c stop it and shake.That is, this shakes is moment extracting upward from adjacent slit 13c to begin shaking of magnetic pole 13b, and the top of the line mouth 11 that descends the turning back a conversion direction of upper end enters initial slit 13c and stopped in the past it and shake.When observing line mouth 11 top this moment mobile centered by magnetic pole 13b, the arc track above Fig. 6 is drawn out on the top of this line mouth 11.Thereby, can make line mouth 11 along the cross sectional shape of magnetic pole 13b around magnetic pole 13b with runway shape rotary moving.
At this, by the round movement along Z-direction of the line mouth 11 of line mouth travel mechanism 30, be with servomotor 33 rotating parts 34 rotations to be carried out by the lifting as drive source.As shown in Figure 3, when making rotating parts 34 rotation, depart from an end of the connecting member 36 that its pivot supported by axle and draw out circular motion according to the order of Fig. 3 (a)～(d).On the other hand, the other end of this connecting member 36 is by traveling table 32 axles supporting that can lifting, therefore the other end of this connecting member 36 becomes moving up and down of Z-direction with traveling table 32, when rotating parts 34 rotates one time, then traveling table 32 carries out back and forth movement one time, and the amount of this back and forth movement equals the value of the twice of the amount R that departs from from the pivot of rotating parts 34.Therefore lifting by making rotating parts 34 to same direction rotation, just can make traveling table 32 back and forth movements and the corresponding number of times of its number of revolutions with 33 of servomotors.
On the other hand, by shaking of the magnetic pole 13b that wound the line, undertaken by making stator core 13 come and go rotation, this rotation makes bar-shaped core 18a (Fig. 1) rotate take its central shaft as pivot with servomotor 19 to carry out by shaking.Because this bar-shaped core 18a is installed on the rotating shaft 19a that shakes with servomotor 19, therefore as shown in Figure 4 and Figure 5, this rotation is by making the rotating shaft 19a that shakes with servomotor 19 carry out to rotate and reverse such as lower angle, and described angle is equivalent to as the magnetic pole 13b of coiling object and the magnetic pole 13b angulation adjacent with this magnetic pole 13b.Therefore, only make rotating parts 34 rotations once by lifting with servomotor 33, and the rotating shaft 19a that shakes with servomotor 19 rotated and reverse with small angle, just can make line mouth 11 magnetic pole 13b on every side with runway shape rotary moving once.Therefore if for example lifting is used the servomotor that can make its rotating shaft 33a per minute rotation 3000 times with servomotor 33, just become and to make line mouth 11 at the Winder of the per minute rotary moving on every side of magnetic pole 13b 3000 times.Therefore, and must make servomotor rotation for several times or tens of times line mouth rotary moving device is in the past once compared, can make significantly the threading speed high speed.
In addition, in Winder 10 of the present invention, wind the line and do not use over employed ball screw type device in order to make line mouth 11 rotary moving around magnetic pole 13b.What the servomotor that therefore need not in the past to make the lead screw shaft in this ball-screw to rotate will carry out begins anxious acceleration and deceleration from high speed.For the lifting servomotor 33 as drive source of the present invention, as long as its rotating shaft 33a is rotated with same speed to same direction, just can make this line mouth 11 along the Z-direction back and forth movement, for shaking with servomotor 19, by repeatedly rotating and reverse with small angle magnetic pole 13b is shaken.Therefore, need not in the past for the required high torque (HT) of the high speed of realizing winding the line, the high servomotor that responds.Therefore, by will as standard items the servomotor of market sale as the present invention in the lifting of Winder 10 with servomotor 33 with shake with servomotor 19 and use, can not increase the unit price of Winder 10 thus and realize the high speed of threading speed, and threading speed can be brought up to this lifting with servomotor 33 and shake with till the capacity limit of servomotor 19.
In addition, for wire rod 12 fitly is wrapped on the magnetic pole 13b, must make line mouth 11 rotary moving around magnetic pole 13b, and wire rod 12 whenever must make stator core 13 move the distance of the amount of the diameter that is equivalent to wire rod 12 along X-direction by fore-and-aft direction drive division 17 around a circle.And when stator core 13 is moved along X-direction, although the fore-and-aft direction servomotor 17c by fore-and-aft direction drive division 17 makes fore-and-aft direction rotating shaft 17b rotate to carry out, it is minimum that yet this amount of movement is that wire rod 12 whenever is equivalent to amount thereby the amount of movement of diameter of wire rod 12 around a circle, thereby need not to make this fore-and-aft direction rotating shaft 17b with High Rotation Speed.Even therefore for the fore-and-aft direction servomotor 17c that makes fore-and-aft direction rotating shaft 17b rotation, therefore also can use as the servomotor of standard items in market sale, can not increase the unit price of Winder 10 and realize the high speed of the threading speed of neat kinking.
And, as shown in Figure 6, because the cross sectional shape of magnetic pole 13b is rectangle, therefore the track by with 11 coiling of line mouth the time is set for: online mouth 11 does not contact that the as close as possible magnetic pole 13b that is wound the line passes through in the scope of the wire rod 12 that is wrapped on the magnetic pole 13b, and the wire rod that therefore can reduce line mouth 11 is derived the gap that produces between end and the quilt magnetic pole 13b that winds the line.Can avoid thus as when coiling occur disorderly around situation, thereby can effectively wire rod 12 neatly be wrapped on the magnetic pole 13b.
In addition, whole magnetic pole 13b are carried out such coiling, and after the coiling to whole magnetic pole 13b finishes, take off stator core 13 from supporting member 18.Carrying out this when taking off, fore-and-aft direction drive division 17 drives its fore-and-aft direction servomotor 17c, makes fore-and-aft direction rotating shaft 17b rotation, shown in the solid arrow of Fig. 1, make supporting member 18 with workbench 16 away from pedestal 31.Under this state, the lifting that is arranged at mounting panel 21 is entered with the bar 24a of cylinder 24, make pressing component 18b with such rise of Lift Part 22 shown in single-point line arrow, remove this pressing component 18b to the pressing of stator core 13, and above this stator core 13, form the space.Then, the stator core 13 that loads in bar-shaped core 18a upper end is taken off from bar-shaped core 18a via this space, thereby finish a series of winding operation.
Another execution mode of expression the present invention in Fig. 8～Figure 12.In this another execution mode, the label identical with device in the previous execution mode represents same parts, and omits repeat specification.
As shown in figure 12, the stator core 63 of this another execution mode is to use internal gear type stator core, has circular annulus 63a and a plurality of magnetic pole 63b, and these a plurality of magnetic pole 63b are outstanding towards the center of this annulus 63a from the inner peripheral surface of this annulus 63a.As shown in Figure 8, has the supporting arrangement 68 that carries such stator core 63 at board 14.This supporting arrangement 68 possesses: be configured in the fixed station 68a on the board 14; Rotating platform 68b, it is installed on this fixed station 68a in the mode that can rotate in horizontal plane, and side is carried fixed stator core 63 thereon; Servomotor is used in not shown shaking, and it makes above-mentioned rotating platform 68b rotation.
The Winder 60 of this another execution mode possesses: board 14, and it has above-mentioned supporting arrangement 68 and is arranged on the place is set; Driver element 70, it is arranged on this board 14, is used for above-mentioned line mouth travel mechanism 30 is driven along the direction of three axles.Driver element 70 is combined by the drive division 71,72,73 of the direction of three axles, possesses fore-and-aft direction drive division 71, left and right directions drive division 72, above-below direction drive division 73.Above-mentioned drive division 71,72,73 is along driving direction X, Y, the roughly the same driving mechanism of Z-shaped one-tenth.
At first, above-below direction drive division 73 is described, this above-below direction drive division 73 disposes: above-below direction guide portion 73a, and it disposes along driving direction Z; Above-below direction rotating shaft 73b, itself and this above-below direction guide portion 73a disposes abreast and in surface configuration pin thread is arranged; Above-below direction moving part 73c, it screws up by ball-screw and this above-below direction rotating shaft 73b, and can move along above-below direction guide portion 73a; Above-below direction connecting portion 73d, it is connected with this above-below direction moving part 73c; Above-below direction drive source 73e, its rotary actuation above-below direction rotating shaft 73b.Above-below direction rotating shaft 73b is connected with above-below direction drive source 73e by Hooks coupling universal coupling 73f.Above-below direction moving part 73c sets it in the moving range of driving direction Z by the scope that is configured in the pin thread on the above-below direction rotating shaft 73b.
Fore-and-aft direction drive division 71 and left and right directions drive division 72 are the structure same with above-below direction drive division 73, along driving direction X, Y configuration as shown in Figure 8.Fore-and-aft direction drive division 71 is fixed on the board 14, has fore-and-aft direction drive source 71e, and is configured to: left and right directions drive division 72 can move along fore-and-aft direction with respect to fore-and-aft direction drive division 71 via fore-and-aft direction connecting portion 71d.Left and right directions drive division 72 has left and right directions drive source 72e, and is configured to: above-below direction drive division 73 can move along left and right directions with respect to left and right directions drive division 72 via left and right directions connecting portion 72d.And as each drive source 71e, 72e, 73e, for example use can high accuracy control servomotor.And at the above-below direction connecting portion 73d of above-below direction drive division 73 line mouth travel mechanism 30 being set, this line mouth travel mechanism 30 makes line mouth 11 move along direction that is the Z-direction vertical with the axle of the magnetic pole 63b that winds the line.
The mechanism that illustrates in this line mouth travel mechanism 30 and formerly the execution mode is same configuration, such as Fig. 8～shown in Figure 10, has: pedestal 31, and it is fixed in the above-below direction connecting portion 73d of above-below direction drive division 73; Traveling table 32, it is arranged at the face in the face of stator core 63 of this pedestal 31 in the mode that can move in the vertical direction; Drive source 33, it constitutes the top that is arranged on pedestal 31, can make rotating parts 34 rotations; Connecting member 36, it links above-mentioned rotating parts 34 and traveling table 32.The face in the face of stator core 63 at pedestal 31 arranges linear motion guide rail 37, and this linear motion guide rail 37 vertically extends, and traveling table 32 is being arranged on along the mode that Z-direction moves on this guide rail 37.In addition, the drive source in the present embodiment is lifting servomotor 33, and rotating parts 34 is directly installed on its rotating shaft.On the other hand, connecting member 36 one ends are supported on the position of the pivot that departs from rotating parts 34 by axle, and the other end is supported on traveling table 32 by axle, and this traveling table 32 is installed in the below of rotating parts 34 in the mode that can move up and down.And, fix wired mouth 11 in the part of the X-direction that is positioned at stator core 63 in the mode of extending along X-direction in the bottom of this traveling table 32.As shown in Figure 9, at traveling table 32 the first pulley 76 is set, this first pulley 76 turns to the wire rod 12 that runs through line mouth 11, at pedestal 31 the second pulley 77 is set, this second pulley 77 makes the wire rod 12 that runs through line mouth 11 and undertaken turning to by the first pulley 76 further turn to towards above-below direction connecting portion 73d.
Below, the method for winding of the wire rod that uses such Winder is described.
At first, make wire rod 12 run through line mouth 11 and derive from the top of line mouth 11.And when beginning to wind the line, driver element 70 make line mouth 11 with line mouth travel mechanism 30 along three-dimensional direction moving, the end of wire rod 12 be wrapped on not shown anchor line (string) pin or the thread-clamping device be fixed.Then, driver element 70 is driven, as shown in Figure 9, among the slit 63c between the magnetic pole 63b that line mouth 11 at horizontal level is moved to be about to wind the line in the stator core 63 and the magnetic pole 63b adjacent with this magnetic pole 63b.Then, then carry out actual coiling, yet when carrying out this actual coiling, by line mouth travel mechanism 30 line mouth 11 is come and gone along Z-direction mobile, and make rotating platform 68b carry out positive rotation and despining with stator core 63 by not shown shaking with servomotor in the supporting arrangement 68, so that the magnetic pole 63b that is wound the line shakes.By the combination of above-mentioned action, make line mouth 11 along the cross sectional shape of magnetic pole 63b around this magnetic pole 63b with runway shape rotary moving.
As shown in figure 11, the rotary moving of this runway shape is: be arranged in when the top of line mouth 11 in the situation of the slit 63c that the magnetic pole 63b that winds the line and the magnetic pole 63b adjacent with the side of this magnetic pole 63b clip, only make this line mouth 11 descend or rise and do not carry out in the supporting arrangement 68 shaking shaking of the magnetic pole 63b that carries out with servomotor by not shown.Then, when extract from this groove 63c on the top of this line mouth 11, beginning magnetic pole 63b shakes, and the adjacent slit 63c between the magnetic pole 63b that is winding the line on the top of this line mouth 11 and the magnetic pole 63b adjacent with the opposing party of this magnetic pole 63b below or above stage, stop it and shake.That is, from initial slit 63c downwards or above moment of extracting begin shaking of magnetic pole 63b, and the top of the line mouth 11 that rises or descend the turning back a conversion direction of lower end or upper end enters before the next adjacent slit 63c, stops it and shakes.Can make thus line mouth 11 along the cross sectional shape of magnetic pole 63b around this magnetic pole 63b with runway shape rotary moving.
As shown in figure 10, line mouth 11 is with servomotor 33 rotating parts 34 rotations to be carried out by the lifting as drive source based on the round movement of line mouth travel mechanism 30.When making rotating parts 34 rotation, an end that departs from the connecting member 36 that its pivot supported by axle carries out circular motion, and according to the order of Figure 10 (a)～(d), the other end of this connecting member 36 carries out back and forth movement with traveling table 32, and the amount of this back and forth movement equals the value of the twice of the amount R that departs from from the pivot of rotating parts 34.Therefore the lifting of line mouth travel mechanism 30 only by making rotating parts 34 to same direction rotation, just can make traveling table 32 back and forth movements and the corresponding number of times of its number of revolutions with servomotor 33.
On the other hand, shaking by making stator core 63 come and go rotation of the magnetic pole 63b that is wound the line undertaken, and this rotation is undertaken by not shown shaking with servomotor in the supporting arrangement 68.The round rotation of this stator core 63 be by make not shown shake to rotate and reverse with following angle with servomotor carry out, described angle is equivalent to as the magnetic pole 63b of coiling object and the magnetic pole 63b angulation adjacent with this magnetic pole 63b.Therefore, only make rotating parts 34 rotation once by lifting with servomotor 33, and not shown shaking with servomotor rotated and reverse with small angle, just can make line mouth 11 magnetic pole 63b on every side with runway shape rotary moving once.Its result must make the lead screw shaft rotation that line mouth rotary moving around magnetic pole is once compared with the past, can realize the high speed of threading speed.
In addition, in the Winder 60 of this another execution mode, make line mouth 11 with the driver element 70 of line mouth travel mechanism 30 along three-dimensional direction moving although have, yet this driver element 70 is using in the following situation: as in the situation of the magnetic pole 63b that changes coiling, the end of the wire rod 12 that maybe will derive from the top of line mouth 11 is wrapped in the inferior line mouth 11 that makes like that of situation that not shown anchor line (string) pin or thread-clamping device be fixed and carries out using when mobile greatlyr.Although therefore this driver element 70 possesses the above-below direction drive division 73 that line mouth 11 is moved up and down along Z axis with line mouth travel mechanism 30, making line mouth 11 when rotary moving winds the line around the magnetic pole 63b, do not use this above-below direction drive division 73.Therefore as the above-below direction drive source 73e of this above-below direction drive division 73, need not to use can be from the high torque (HT) of carrying out at a high speed anxious acceleration and deceleration, the servomotor of high response.And for lifting servomotor 33, as long as be rotated with same speed to same direction, just can make this line mouth 11 along the Z-direction back and forth movement, for not shown shaking servomotor, by repeatedly rotating and reverse with small angle magnetic pole 63b is shaken.Therefore by using with servomotor 33, not shown shaking with servomotor as above-below direction drive source 73e, the lifting of this another Winder 60 as the servomotor of standard items in market sale, can not increase the unit price of Winder 60 thus and realize the high speed of threading speed.
In addition, for wire rod 12 fitly is wrapped on the magnetic pole 63b, must make line mouth 11 rotary moving around magnetic pole 63b, and wire rod 12 must make line mouth 11 move the distance of the amount of the diameter that is equivalent to wire rod 12 along X-direction with line mouth travel mechanism 30 by fore-and-aft direction drive division 71 whenever around a circle.When this line mouth 11 is moved along X-direction, to make fore-and-aft direction connecting portion 71d move to carry out along X-direction by the fore-and-aft direction drive source 71e that drives fore-and-aft direction drive division 71, yet this amount of movement is wire rod 12 whenever only is equivalent to the diameter of wire rod 12 around a circle amount, thereby amount of movement is few, thereby need not to make fore-and-aft direction drive source 71e with high-speed driving.Even therefore using in the situation of servomotor as this fore-and-aft direction drive source 71e, also can use as the product of standard items in market sale, thereby the unit price that can not increase Winder 60 can obtain the Winder 60 that neatly twines with at a high speed.
In addition, in the above-described embodiment, illustrated and used servomotor as the situation of drive source, yet also can use stepping motor as drive source.
In addition, following situation has been described in the above-described embodiment: by line mouth travel mechanism 30 line mouth 11 is come and gone along Z-direction mobile, and make stator core 13,63 carry out positive rotation and despining, so that the magnetic pole 13b that is wound the line, 63b shakes, and make line mouth 11 come wound wire 12 with runway shape rotary moving by the combination of these actions, yet when being moved up and down, also moves to Y direction in online mouth 11, combination by these actions makes line mouth 11 rotary movings, also can be by making synchronously stator core 13 with moving up and down of line mouth 11,63 itself move to Y direction is round, thus wire rod 12 are wrapped in magnetic pole 13b, on the 63b.Even also can effectively wire rod 12 be wrapped on magnetic pole 13b, the 63b in this case.
In addition, in above-mentioned another execution mode, the driver element 70 that line mouth travel mechanism 30 is driven along the direction of three axles has been described, yet this driver element being not limited to three direction of principal axis, also can be an axle or two axles among X, Y, the Z.For example, also can workbench 16 be installed on board 14 such as Figure 13 and shown in Figure 14, and via the fore-and-aft direction drive division 87 that line mouth travel mechanism 30 is moved along X-axis, this line mouth travel mechanism 30 be installed on board 14.Fore-and-aft direction drive division 87 among Figure 13 and Figure 14 disposes: fore-and-aft direction guide portion 87a, and it is configured on the board 14 along the X-axis as driving direction; Fore-and-aft direction rotating shaft 87b, itself and this fore-and-aft direction guide portion 87a disposes abreast, and surface configuration has spiral helicine pin thread; Fore-and-aft direction drive source 87c, its rotary actuation fore-and-aft direction rotating shaft 87b.Winder 10 if so, then can reduce the width of Y direction, as shown in figure 14, if on prolongation platform 41, along Y direction a plurality of line mouths 11 are installed side by side, just can enough line mouth travel mechanisms 30 simultaneously a plurality of stator cores 13 (Fig. 1) be wound the line.
