(winding process)
In this operation, thereby wire rod 13 is wound into the circle acquisition is drawn lead-out wire 13a, 13b from the position of regulation circular coil 11.Like Fig. 3 and shown in Figure 4; This coiling utilizes coil winding machine 20 to carry out; Papery bobbin 14 is embedded in its spools 24, and the end of the wire rod 13 that will derive from line mouth 26 is as the end of a thread wire rod 13, is the grips 28 that is arranged on the side around the disk 23 is controlled it.And, after this end of a thread wire rod 13 is directed to the groove 24c of the upper limb that is formed at large-diameter portion 24b, drives coiling and make its spool 24 rotations with motor 21, the wire rod 13 of deriving from the top of line mouth 26 is wound on the papery bobbin 14.And, when carrying out this coiling, through line mouth travel mechanism 27 line mouth 26 is moved back and forth along Z-direction, thereby wire rod 13 fitly is wrapped on this papery bobbin 14.After making the wire rod 13 coiling regulation number of turns; To be directed to the groove 24c of the upper limb that is formed at large-diameter portion 24b from the wire rod 13 that line mouth 26 is derived; Then, as the wire rod 13 of line tail, be that the grips 29 that is arranged on the opposing party around the disk 23 is controlled it.So wire rod 13 is wound on the papery bobbin 14 of tubular, thereby around papery bobbin 14, forms circular coil 11.
Wherein, When the insulating coating of wire rod 13 for through the bonding material in heating fusion and cooling back the time; Utilize 81 pairs of circular coils of air-heater 11 to spray hot blast; Thereby the insulating coating that makes this wire rod 13 is melt bonded wire rod 13 is bonded together each other, and this circular coil 11 is bonded on the papery bobbin 14, the shape of the circular coil 11 that constitutes with the wire rod 13 that prevents by proper alignment after scatter.Then, the end of a thread wire rod 13 is taken off from grips 28, and near grips 29, line buttock line material 13 is cut off.So the lead-out wire 13a, the 13b that are made up of this end of a thread wire rod 13 and line buttock line material 13 are housed among the groove 24c, thereby obtain the circular coil shown in Figure 4 11 that lead- out wire 13a, 13b always draw from certain assigned position.
(conveying operation)
In this operation, circular coil 11 is transported to make-up machine 30 from coil winding machine 20.The conveying of this circular coil 11 is undertaken by supply unit 60, and driving is carried with motor 64 and operated with motor 71, makes to carry and moves along X axle and Z axle with cylinder 72, and make this conveying be positioned at the top of coil winding machine 20 with cylinder 72.And; Widen carry with the mutual interval of a pair of front and back movable member 72a, the 72a of cylinder 72 after; This conveying is descended with cylinder 72, make like Fig. 4 and shown in Figure 11 to be arranged on last a pair of of this a pair of movable member 72a, 72a and to control the both sides that sheet 74,74 is positioned at the X-direction of circular coil 11.And, thus a pair of sheet 74, the 74 mutual intervals of controlling are narrowed down through dwindling a pair of front and back movable member 72a, the mutual interval of 72a.And in order not damage papery bobbin 14; And a pair of sheet 74, the 74 mutual intervals of controlling are narrowed down to the degree that contact-making surface 74a that a pair of outer peripheral face with circular coil 11 of controlling sheet 74,74 contacts is slightly less than the external diameter of this circular coil 11; Shown in figure 12 thus, from the both sides of X-direction therebetween circular coil 11 is controlled from its outside.At this moment; The lead-out wire 13a of circular coil 11,13b are contained in the groove 24c on the spool 24 (Fig. 4); Therefore can this lead-out wire 13a, 13b always be remained on certain assigned position, and control from the outside to circular coil 11 through a pair of sheet 74,74 of controlling.
And; When controlling this circular coil 11; Not shown air attractor; Attract air via an end at a pair of airport 77 of controlling the contact-making surface 74a upper shed that sheet 74,74 contacts with the outer peripheral face of circular coil 11, circular coil 11 is adsorbed on this circular coil 11 is carried out a pair of of clamping and controls on the sheet 74,74.Even a pair of thus to control sheet 74,74 mutual opposed contact-making surface 74a be the degree that is slightly less than the external diameter of this circular coil 11, also can control this circular coil 11 effectively through a pair of sheet 74,74 of controlling.Then, driving operations is with motor 71, makes to carry with cylinder 72 with circular coil 11 risings, will controlled the circular coil 11 that sheet 74,74 controls and extracted from spool 24 by a pair of.Then, driving is carried with motor 64 and is operated with motor 71 both sides, makes to carry with cylinder 72 and circular coil 11 and moves towards make-up machine 30 together, makes this circular coil 11 be arranged in the below of a pair of extension part spare 31,31 of make-up machine 30.
(forming process)
In this operation, the interval that in make-up machine 30, will enter at least one pair of extension part spare 31,31 of these circular coil 11 inboards is widened, and circular coil 11 is configured as non-circular coil 12.Circular coil 11 is arranged in the below of make-up machine 30 a pair of extension part spares 31,31; When therefore a pair of extension part spare 31,31 gets into circular coil 11 inboards; Carry out through following method:, above-below direction movable plate 35 is descended by like Fig. 5 with shown in Figure 6 make 34 rotations of above-below direction rotating shaft with motor 36 up and down.At this moment, movable member 44 rises to utilize up-down as shown in Figure 7 to make up and down with motor 45, opens the active force with spring 43 by expansion, and a pair of parts 41, the 41 mutual intervals that move forward and backward are dwindled.When a pair of parts 41,41 mutual intervals that move forward and backward when dwindling; The interval that a pair of extension part spare 31,31 also dwindles each other; When a pair of extension part spare that has dwindled mutual interval 31,31 descends with above-below direction movable plate 35; As shown in Figure 8, these a pair of extension part spare 31,31 its both sides enter into the inboard of circular coil 11.
Then, the interval of a pair of extension part spare 31,31 is widened, circular coil 11 is configured as non-circular coil 12.This is through carrying out movable member 44 declines up and down by going up and down with motor 45; When movable member 44 descends up and down; A pair ofly move forward and backward parts 41,41 opposing and expand to open with the active force of spring 43 and widen mutual interval, a pair of extension part spare 31,31 is also widened mutual interval with these a pair of parts 41,41 that move forward and backward.As shown in Figure 9; When the interval of a pair of extension part spare 31,31 is widened; Circular coil 11 by should be a pair of extension part spare 31,31 widen in X-direction from the inboard, this circular coil 11 is shaped as by arc sections 12a that forms semicircle shape and the non-circular coil 12 (Figure 19) with oval shape cross section that respectively the line part 12b of the end binding of this arc sections 12a constituted.
When the interval that will enter into the inboard extension part spare 31 of this circular coil 11 is widened, by extension part spare 31 with control the wire rod 13 that 74 pairs of sheets constitute circular coil 11 and carry out clamping.Like Figure 11 and shown in Figure 12, the supply unit 60 in this execution mode is provided with between front and back movable member 72a and slide block 73a and controls with spring 76, this control with spring 76 so that a pair of sheet 74,74 of controlling with this slide block 73a approaching mode application of force each other.Therefore as shown in Figure 9; When enter into the inboard a pair of extension part spares 31,31 of circular coil 11 widen therebetween at a distance from and with this circular coil 11 from the inboard when X-direction is widened, a pair of sheet 74,74 of controlling also resist to control with the active force of spring 76 and is expanded with mutual with the outer peripheral face state of contact of this circular coil 11.Therefore only through widening the interval of extension part spare 31, this controls sheet 74 just can carry out clamping to the wire rod 13 that constitutes circular coil 11 with extension part spare 31.
Wherein, Circular coil 11 is transported to a pair of sheet 74,74 of controlling of this make-up machine 30; With the lead-out wire 13a of circular coil 11, the position that 13a always remains on regulation; And control from the outside to circular coil 11; When being shaped, also the wire rod 13 that constitutes circular coil 11 is carried out clamping, so wire rod 13 can not control sheet 74 with respect to this and move with extension part spare 31, in this forming process with this control the lead-out wire 13a in the circular coil 11 that sheet 74 is a benchmark, the position of 13b can not change.So like Fig. 9, Figure 15 and shown in Figure 19, even at this circular coil 11 through being shaped and becoming under the situation of oblong non-circular coil 12, with this control the lead-out wire 13a that sheet 74 is a benchmark, the position of 13b can not change yet.Therefore in the manufacturing installation and manufacturing approach thereof of non-circular coil 12 of the present invention, always can obtain the non-circular coil 12 that lead- out wire 13a, 13b draw from the position of regulation.
When being configured as non-circular coil 12 at the interval of widening a pair of extension part spare 31,31 and with circular coil 11 or after, contact component 86 intersected with the moving direction of extension part spare 31 and contact with non-circular coil 12 from the outside of non-circular coil 12.The contact of this contact component 86 in this execution mode, is explained the situation that after being configured as non-circular coil 12, contact component 86 is contacted with it through carrying out like Figure 13 and contact mechanism 85 shown in Figure 14.Therefore after being configured as non-circular coil 12 at the interval of widening a pair of extension part spare 31,31 and with circular coil 11; Conveying in the supply unit 60 is widened with a pair of sheet 74,74 of controlling with the mutual interval of a pair of front and back movable member 72a, the 72a of cylinder 72; Shown in figure 11, remove this and a pair ofly control controlling of 74,74 pairs of non-circular coils 12 of sheet.At this moment, stop the air attractor, remove non-circular coil 12 to the absorption of controlling sheet 74.Keep circular coil 11 is configured as the interval of a pair of extension part spare 31,31 of non-circular coil 12 then, and, make 34 rotations of above-below direction rotating shaft, and above-below direction movable plate 35 is risen with this non-circular coil 12 through using motor 36 up and down.Then, a pair of sheet of having removed non-circular coil 12 74,74 of controlling of controlling moves towards coil winding machine 20, gets into the SBR that the next circular coil of being made by this coil winding machine 20 11 is controlled.
Make non-circular coil 12 after a pair of extension part spare 31,31 rises; The turnover axle 92a that pushes with cylinder 92 in the contact mechanism 85 is given prominence to; Level board 91 is moved, and the jag of the level board 91 after this is moved is positioned at the below of a pair of extension part spare 31,31.In two movable table 93,93 of the jag that is arranged on level board 91, a pair of extension part spare from Y direction clamping make-up machine 30.And, shown in figure 16, outstanding through the turnover axle 94a that makes miniature cylinder 94, thus the contact component 86 and the moving direction of extension part spare 31 are intersected, and contact with this non-circular coil 12 from the outside of non-circular coil 12.Wherein, the amount of its contact is adjusted through mircrometer gauge 96 (Figure 13 and Figure 14) in advance.
Wherein, When the insulating coating of wire rod 13 for through the bonding material in heating fusion and cooling back the time; When circular coil 11 being configured as non-circular coil 12 and when the non-circular coil 12 of contact component 86 and this is contacted, spray hot blasts to this non-circular coil 12, make the insulating coating of this wire rod 13 melt bonded once more through air-heater 81; The wire rod 13 that constitutes non-circular coil 12 is bonding each other again, and should be bonded on the papery bobbin 14 by non-circular coil 12.Like this through contact component 86 is contacted with non-circular coil 12; The wire rod 13 of line part 12b in this non-circular coil 12 is alignd as the crow flies; The wire rod 13 of this straight alignment is bonding each other, thus crooked situation prevented like the line part 12b in the non-circular coil 12.Therefore contact component 86 can not make the line part 12b in the non-circular coil 12 crooked to the inside.
Then, the amount of these contact component 86 contacts can be adjusted through mircrometer gauge 96, therefore just can access line part 12b with anticipated shape through the amount of adjusting this contact.In addition; Under the situation that this non-circular coil 12 is made up of the wire rod 13 that is wound on the papery bobbin 14; The non-circular coil 12 that can the wire rod 13 by this straight alignment be constituted is bonded on this papery bobbin 14; Therefore can eliminate the papery bobbin 14 and the dislocation between the non-circular coil 12 that produce because of shaping, so can prevent that this non-circular coil 12 from peeling off from papery bobbin 14.The shape that can prevent non-circular coil 12 thus after the situation of scattering, obtain the lead-out wire 13a that constitutes by the end of a thread wire rod 13 and line buttock line material 13 as Figure 19 (b) shown in, the non-circular coil 12 that 13b always draws from certain assigned position.
Resulting non-circular coil 12 descends with a pair of extension part spare 31,31 (Fig. 5 and Fig. 6) afterwards, dwindles the interval of this a pair of extension part spare 31,31, and non-circular coil 12 is taken off from this make-up machine 30.At this moment,, make to take out and move, make this taking-up be positioned at the upside of non-circular coil 12 with pawl 97 with the non-circular coil 12 of pawl 97 after descending by taking out with cylinder 98.Under this state, dwindle the interval of a pair of extension part spare 31,31, a pair of extension part spare 31,31 is further risen.At this moment, even non-circular coil 12 cards hang on a pair of extension part spare 31,31, this non-circular coil 12 also can contact with pawl 97 with taking-up, thereby prevents that it from rising with a pair of extension part spare 31,31.Can effectively non-circular coil 12 be extracted from a pair of extension part spare 31 thus.Be pulled out and the non-circular coil 12 that falls is transferred the outside of catching and be discharged to this device 10 with 99 from a pair of extension part spare 31 then, take out to take out with pawl 97 and be withdrawn into again near the mounting panel 32 with cylinder 98.Finish a series of manufacturings of a non-circular coil 12 thus, and begin the manufacturing of next non-circular coil.
Wherein, In the above-described embodiment; Situation when the non-circular coil 12 of contact component 86 and this is contacted is illustrated; But also can form: shown in figure 18, when circular coil 11 is configured as non-circular coil 12, the non-circular coil 12 of contact component 86 and this is contacted.Even in this case, contact component 86 also can make this non-circular coil 12 contact with papery bobbin 14 and be bonding, thereby prevents that this non-circular coil 12 from peeling off from papery bobbin 14.
In addition; In the above-described embodiment; Coil winding machine 20 to obtain circular coil 11 through wound skein product 13 on papery bobbin 14 is illustrated; But circular coil 11 is not limited to be made up of the wire rod 13 that is wound on the papery bobbin 14, also can be the so-called exoskeletal coil that does not use papery bobbin 14.In addition, even when using bobbin 14, this bobbin 14 also is not limited to the papery bobbin, and can be resinous bobbin, obtain the bobbin that constitutes by nonmagnetic film.Wherein, as the resinite bobbin, the resinite bobbin 14 of preference as constituting by polyimide film (trade name: Kapp is logical).
