Like Fig. 6～shown in Figure 9, silk handle sturcture 40 have be located at the fixedly introducer 41 (fixed part) that anti-silk drops on the thread-carrier 31, can not move along its axis with respect to bare bobbin 20b integratedly and be located at integratedly silk near on the thread-carrier 30, can with silk near thread-carrier 30 with respect to bare bobbin 20b and fixedly introducer 41 along the axially movable movable part 42 of bare bobbin 20b.Fixedly introducer 41 is same near a plurality of engagement section 30a of thread-carrier 30 with a plurality of notch 31a and the silk of the anti-thread-carrier 31 that drops with movable part 42, is provided with a plurality of corresponding to a plurality of bobbins 20.
Fixedly introducer 41 has along drop base portion 41a that thread-carrier 31 extends and be divided into two strands of shapes and with respect to the base portion 41a guiding part 41b of diagonally extending downwards from the end of this base portion 41a of anti-silk.And; Fixedly introducer 41 drops under the state of the notch 31a on the thread-carrier 31 towards being formed at anti-silk at the guiding part 41b of two strands of shapes, base portion 41a through two screw retention on tabular anti-silk drops the back side (with the opposed faces of silk near thread-carrier 30) of leading section of thread-carrier 31.
Shown in Fig. 8 (a), Fig. 8 (b); Silk drops the state of thread-carrier 31 after entering into bare bobbin 20b and the full silk road Y2 between the package 21 (thread near preceding state) near thread-carrier 30 and anti-silk under; Silk is on the axial position about equally of bobbin 20 near the engagement section 30a of thread-carrier 30 and the notch 31a of the anti-thread-carrier 31 that drops, and the silk Y that is fastened on engagement section 30a and notch 31a becomes the axial roughly state of quadrature with respect to bobbin 20.In addition, be located at silk near the movable part on the thread-carrier 30 42 be located at the fixedly introducer 41 that anti-silk drops on the thread-carrier 31 and be positioned at opposition side each other across engagement section 30a and notch 31a.
Begin from this state; As shown in Figure 9; If silk is driven near axial (direction of the arrow B of Fig. 9) of thread-carrier 30 along bobbin 20 through fluid pressure cylinder 33 (with reference to Fig. 2); Then be fastened on silk and drop under the state among the notch 31a of thread-carrier 31 being fastened on anti-silk near the silk Y on the engagement section 30a of thread-carrier 30, silk near the effect of thread-carrier 30 under near underwinding position to the bobbin end.At this moment, be located at integratedly silk near the movable part on the thread-carrier 30 42 also with respect to fixing introducer 41 moving axially along bobbin 20.And the movable part 42 that is made up of leaf spring pushes the silk Y between engagement section 30a and the notch 31a on one side to the fixing guiding part 41b of two strands of shapes of introducer 41, on one side through its spring energized pushing Y, and assists with guiding part 41b and to control (clamping) Y movingly.
Here because silk Y is by being supplied with from spinning machine continuously, so if at movable part 42 with fixedly control a Y between the introducer 41b, the tension force of silk Y of then controlling the upstream side of position reduces sharp, silk Y moment relaxes.Therefore, silk Y is wrapped on the bare bobbin 20b, and begins the formation of the underwinding 22 of bare bobbin 20b through the rotation of spool stand 13b.Like this, if owing to control a Y then a silk Y is wrapped on the bare bobbin 20b at once, so the timing that the timing of controlling a Y and underwinding begin about equally.Therefore, only begin just can correctly manage the underwinding amount near state to keeping a time of silk near thread-carrier 30 through setting from controlling a Y.
Then, the electric of wire coilling device 1 described simple in structurely.As shown in Figure 1, in frame 10, be provided with the control setup 50 of molar behavior of control wire coilling device 1.This control setup 50 by as the CPU (Central Processing Unit) of arithmetic processing apparatus, store the ROM (Read-Only Memory) of program that CPU carries out and the data of in program, using and be used for the RAM formations such as (Random Access Memory) of when program is carried out temporary storaging data.And; This control setup 50 based on by the operator from being located at the instruction of operating case 51 input on the frame 10, the control rotation drives the action of each one of the motor of turntable 12, the fluid pressure cylinder 33 of motor, traverse gear 14, touch roll 15 and guide wire apparatus 16 that rotation drives spool stand 13 etc., wire coilling device 1.
Then, a series of action when switching the bobbin of wire coilling device 1 describes.
Shown in Fig. 7 (a); If be in completely package 21 of formation on the bobbin 20a of the spool stand 13a that batches position P1; Then shown in Fig. 7 (b); Make turntable 12 to the direction of arrow (anticlockwise direction) Rotate 180 degree, make the spool stand 13b that is in position of readiness P2 move to silk and batch position P1, make a Y contact on the bare bobbin 20b that is installed on this spool stand 13b.
And then, turntable 12 is revolved to the direction of arrow turn 90 degrees, shown in Fig. 7 (c), make the spool stand 13 that bare bobbin 20b is installed move to a delivery position P3.Then; Make the silk of guide wire apparatus 16 move to the in-position of representing by solid line from the retreating position of representing by long and two-short dash line, make the leading section of two introducers 30,31 enter into the silk road Y2 that arrives completely package 21 via bare bobbin 20b near thread-carrier 30 and the anti-thread-carrier 31 that drops.So; Being fastened on silk in the silk part of silk road Y2 drops near the engagement section 30a of thread-carrier 30 and anti-silk under the state in the notch 31 of thread-carrier 31; This part is boosted, and the silk part of silk road Y2 approaches near the silk road Y1 from touch roll 15 to bare bobbin 20b.Thus, the roughly complete cycle of the outer peripheral face of bare bobbin 20b is touched in wire connection.In addition, this moment is as shown in Figure 3, and in the engagement section 30 of silk near thread-carrier 30, the silk part of silk road Y2 is fastened on its deep, and contains the silk part of a road Y1.
This near preceding state under; As shown in Figure 8; Silk is in axially about equally the position of bobbin 20 near the drop notch 31a of thread-carrier 31 of the engagement section 30a of thread-carrier 30 and anti-silk, advances with the axial roughly direction of quadrature of bobbin 20 in the silk Y edge that engage with engagement section 30a and notch 31a.Begin from this state, through fluid pressure cylinder 33 with silk near thread-carrier 30 with respect to thread-carrier 31 axial (the arrow B direction of Fig. 9) driving of dropping of anti-silk along bobbin 20.So; Shown in Fig. 9 (a), Fig. 9 (b);, make the silk part of the silk road Y2 that is fastened among the 30a of engagement section and be housed in the underwinding position of the silk part of the silk road Y1 in the 30a of engagement section near thread-carrier 30 through silk near the axial end portion outside, bobbin 20 of the scope of the traversing T of traverse gear 14 (introducer 14a traverses).
At this moment, being located at silk moves with respect to being located at axial (the arrow B direction of Fig. 9) of anti-fixedly introducer 41 on the thread-carrier 31 that drops along bobbin 20 near the movable part 42 that is made up of leaf spring on the thread-carrier 30 simultaneously.Then, movable part 42 is pushed into silk among the guiding part 41b of fixing two strands of shapes of introducer 41 near drop silk Y between the notch 31a of thread-carrier 31 of the engagement section 30a of thread-carrier 30 and anti-silk, assists with guiding part 41b and controls a Y movingly.
If control a Y through movable part 42 and fixing introducer 41 like this, then thread tension reduces sharp, and a silk Y promptly is wrapped on the underwinding position of bare bobbin 20b, and begins to form underwinding 22 to bare bobbin 20b through the rotation of spool stand 13.In addition, owing to side by side silk Y is wrapped on the bare bobbin 20b with controlling roughly of silk Y, the amount of underwinding 22 (volume number) roughly exists with ... from controlling the time length near state near thread-carrier 30 that a Y begins.So,, can correctly manage the amount of underwinding 22 through will this silk maintaining predefined specified time near state near the silk of thread-carrier 30.Particularly, silk is stored in the storage part of control setup 50 near the time length of state in advance, through the time control fluid pressure cylinder 33 of control setup 50 according to this storage, makes a silk near thread-carrier 30 only continue the time of setting near state.
In addition, if begin to form underwinding 22 to bare bobbin 20b, the bigger tension force of effect on the silk part of bare bobbin 20b and the full silk road Y2 between the package 21 then, the mode of under the effect of this tension force, being broken with quilt is cut off a Y.As a result, with silk from full package 21 guiding bare bobbin 20b.
In addition; If control a Y through silk handle sturcture 40; Then a silk Y promptly is wrapped on the bare bobbin 20b, if formation then the bare bobbin 20b of beginning underwinding 22 are cut off with the full silk Y between the package 21 immediately, so keeping silk near thread-carrier 30 thread near state during; Even through silk handle sturcture 40 controlling the silk Y state, also obstacle can't take place.
If control the underwinding 22 that a Y begins to form through predefined specific time, at bare bobbin 20b desired amount from silk handle sturcture 40 (movable part 42 reaches fixedly introducer 41); Then through silk being driven near the axial opposed side (with the arrow B opposition side of Fig. 9) of thread-carrier 30 to bobbin 20 by fluid pressure cylinder 33; As shown in Figure 8, make silk get back to original position near thread-carrier 30.At this moment, silk handle sturcture 40 (movable part 42 reaches fixedly introducer 41) also is disengaged the gripping state of silk Y.And then, make silk keep out of the way the retreating position of the long and two-short dash line of Fig. 7 (c) near thread-carrier 30 and the anti-thread-carrier 31 that drops.So, since silk carry out near the engagement section 30a of thread-carrier 30, silk Y bobbin 20 axially on mobile restriction be disengaged, so a silk Y is traversed in the scope T that traverses by the introducer 14a that traverses of traverse gear 14 vertically.
And then, rotate to direction of arrow opposite sense (clockwise direction) through making turntable 12 with Fig. 7, make the spool stand 13 that bare bobbin 20b is installed move to silk and batch position P1 from silk delivery position P3, the outer peripheral face contact that makes bare bobbin 20b is on touch roll 15.Thus, applying under the state of contact pressure, silk Y is being traversed in the scope T that traverses through the introducer 14a that traverses on one side batch on one side, formation package 21 on bobbin 20 through 15 pairs of silk layers of touch roll.
In the wire coilling device of above explanation; Make near thread-carrier 30 through silk from bare bobbin 20b after the silk Y of full package 21 is near the underwinding position; Control this Y through silk handle sturcture 40; Silk Y promptly is wrapped on the bare bobbin 20b so thread tension sharply reduces, and is difficult for taking place silk and twines bad.And then if carry out controlling of 40 couples of silk Y of a handle sturcture, then silk Y is wrapped on the bare bobbin 20b immediately, so can grasp the timing that underwinding begins.Therefore; After controlling a Y through silk handle sturcture 40; Only, just can correctly manage the amount of underwinding 22, can prevent easily that the underwinding amount is inhomogeneous between package 21 through making silk keep predefined specific time near state near the silk of thread-carrier 30.
In addition, a silk handle sturcture 40 constitutes, through fixing introducer 41 and can with respect to this fixedly introducer 41 move to the association of the axially movable movable part 42 of bobbin 20 and control a Y.And then fixedly introducer 41 is located on the anti-thread-carrier 31 that drops integratedly, and movable part 42 is located at silk integratedly near on the thread-carrier 30.Therefore; Under the state that the thread-carrier 31 that drops through anti-silk prevents to drop from the silk of completely package 21; Through silk near thread-carrier 30 moving axially along bobbin 20; Make a Y near the underwinding position by silk near thread-carrier 30, and through be located at silk near the movable part on the thread-carrier 30 42 be located at the fixedly introducer 41 that anti-silk drops on the thread-carrier 31 and control a Y.According to this structure, the movable part 42 through making a handle sturcture 40 moves near thread-carrier 30 with silk integratedly, can carry out simultaneously to the silk of underwinding position near with the controlling of thereafter silk Y, simplify the structure so can make.
In addition, in the scope that does not break away from purport of the present invention, various changes that can be following in addition to above-mentioned embodiment.In addition, in following explanation, give identical label and suitably omit its explanation for the part that has with the same structure of above-mentioned embodiment.
In the above-described embodiment; The fixedly introducer 41 of silk handle sturcture 40 and movable part 42 are located at anti-silk respectively integratedly and drop thread-carrier 31 and silk near on the thread-carrier 30; But also can constitute; Drop thread-carrier 31 or silk of introducer 41 and movable part 42 and anti-silk is provided with near thread-carrier 30 individually, and movable part 42 can move moving axially along bobbin 20 independently near the slip of thread-carrier 30 with silk.
In the above-described embodiment, in order to increase the winding angle of a Y, be positioned at bare bobbin 20b and batch from silk under the state that position P1 revolves the silk delivery position P3 after turning 90 degrees again, carry out from full package 21 to the silk handing-over of bare bobbin 20b to bare bobbin 20b.But; Various conditions according to kind and the thread tension etc. of the silk Y that batches; Silk relatively be difficult for taking place to bare bobbin 20b twines under the situation of failure, also can bare bobbin 20b be positioned at silk batch position P1 and completely package 21 be positioned at and carry out silk under the state of position of readiness P2 and join.
