On the other hand, constitute: be inserted under the state of coupling aperture 76b at inner couplings axle 70e, when behaviour's acting cylinder 95 makes this bar 95a get into once more shown in the solid line arrow, then can the inner couplings axle 70e that has inserted be extracted from this coupling aperture 76b.Constitute like this: hold line bobbin 70 by this second locking mechanism 76 can dismounting in rotating shaft 75a as the servomotor 75 of drive source.Hold the both sides that line bobbin 70 can just change and reverse by this servomotor 75 around the Y axle with the rotating shaft 75a of servomotor 75 links.And this holds line bobbin 70 and accumulates through the wire rod 11 that just transfers coiling and derive from wire rod exporter 50, after accumulating wire rod, unclamps the wire rod 11 of being reeled through reversing and wire rod 11 is held line bobbin 70 from this derive.
Like Fig. 4 and shown in Figure 5, fluid-pressure cylinder 92 is parts that sliding part 92a that this servomotor 75 is installed is moved along X-direction.Therefore holding under the state of rotating shaft 75a (Figure 10) that line bobbin 70 is installed on servomotor 75; When this servomotor 75 when leaving the direction of twining anchor clamps 21 and move; Then hold line bobbin 70 and also move, thereby give constant tension force the wire rod 11 that holds 70 derivation of line bobbin from this to leaving the direction of twining anchor clamps.In addition, when giving this tension force, do not drive servomotor 75, do not hold 70 rotations of line bobbin thereby can not make.
And, on movable table 77, be provided with: proximity transducer 97, it detects this sliding part 92a near the situation of twining anchor clamps 21; Separation sensor 98, it detects this sliding part 92a from twining the situation that anchor clamps 21 leave.Each transducer the 97, the 98th is when the transducer of the opposed time output connection signal with the first projection 92d that is arranged at sliding part 92a; As shown in Figure 3; The opposed position of the first projection 92d when twining anchor clamps 21 with sliding part 92a is approaching is provided with proximity transducer 97; As shown in Figure 2, the opposed position of the first projection 92d when leaving from twining anchor clamps 21 with this sliding part 92a is provided with separation sensor 98.The detection of each transducer 97,98 output be connected as the control device of the servomotor 75 of drive source that is not shown controller.And this controller constitutes: as shown in Figure 3 when proximity transducer 97 is exported connection signal because of holding line bobbin 70 near winding anchor clamps 21; Then drive servomotor 75; As shown in Figure 2ly leave when twining anchor clamps 21 and exporting connection signal because of holding line bobbin 70 when separation sensor 98, the servomotor 75 that is driving is stopped.Control servomotor 75 through controller with this mode, when holding line bobbin 70 when twining anchor clamps 21, then derive wire rods 11 thus, leave when twining anchor clamps 21, forbid deriving wire rods 11 from holding line bobbin 70 when holding line bobbin 70 from holding line bobbin 70.
And, restriction also being set on this movable table 77 moving with cylinder 93, this restriction is mobile can forbid or allow sliding part 92a mobile in the fluid-pressure cylinder 92 with cylinder 93.This restriction is moved with cylinder 93 be arranged at movable table 77 with the mode with fluid-pressure cylinder 92 quadratures along Z-direction with being extended.On the other hand, as shown in Figure 4ly leave when twining anchor clamps 21 holding line bobbin 70, face limitations moves the sliding part 92a that is installed on fluid-pressure cylinder 92 with the second projection 92c of cylinder 93.The sliding part 93a that restriction is moved with cylinder 93 is provided with snap-latch piece 93c, and this snap-latch piece 93c engages with the second projection 92c according to having or not of fluid pressure supply or breaks away from from this second projection 92c.And constitute: when the main body 93b that moves to restriction with cylinder 93 supplies with fluid and that kind of sliding part 93a shown in the solid arrow of Fig. 4 moved; When the snap-latch piece 93c that is arranged at is here engaged with the second projection 92c; The moving of sliding part 92a of then forbidding fluid-pressure cylinder 92; And thereby that kind of sliding part 93a shown in the dotted arrow of Fig. 4 restored and to be made snap-latch piece 93c when the second projection 92c breaks away from when the supply of fluid stops, and then allows sliding part 92a mobile of fluid-pressure cylinder 92.
In addition, though not shown, will heat and make the heat blower of its heat bonding be arranged at pallet 19 being wound in wire rod 11 on the core 22 that twines anchor clamps 21.
Next, the method for winding of the present invention that has used above-mentioned Winder is described.
Method for winding of the present invention is following method: will be wound in from the wire rod 11 that wire rod exporter 50 is derived and hold line bobbin 70; Winding anchor clamps 21 are held line bobbin 70 with this be rotated driving; To be wound in from the wire rod 11 that wire rod exporter 50 is derived and twine anchor clamps 21 and after forming first coil 12; Rotation will drive winding anchor clamps 21 under the state after anchor clamps 21 take off from twining holding line bobbin 70; Will be from holding that line bobbin 70 unclamps and the wire rod 11 of deriving is wound in and twines anchor clamps 21, thus second coil 13 formed.Below, each operation is detailed.
< holding line procedures >
In this operation, will be wound in from the wire rod 11 that wire rod exporter 50 is derived and hold line bobbin 70.This coiling carries out through drive source 75, holds line bobbin 70 and is installed on the rotating shaft 75a as the servomotor 75 of drive source by second locking mechanism 76 with the mode that can not rotate.This installation is carried out in the following manner: the bar 95a of behaviour's acting cylinder 95 shown in Figure 10 is got into as the solid line arrow is represented; Make the active force of functional unit 76 antagonistic spring 76d and retreat; And under this state, inner couplings axle 70e is inserted coupling aperture 76b, make bar 95a outstanding as dotted arrow is represented then.Utilize restriction shown in Figure 4 to move with cylinder 93 this snap-latch piece 93c engage with the second projection 92c this moment, forbids being provided with sliding part 92a mobile of the fluid-pressure cylinder 92 of servomotor 75, can forbid the useless mobile of servomotor 75, so be preferred.
And drive servomotor 75 and make its rotating shaft 75a, will be wound in from the wire rod 11 that wire rod exporter 50 is derived thus and hold line bobbin 70 with holding 70 rotations of line bobbin.Its detailed order is: at first cutter sweep 59 is remained on position of readiness.Utilize the sheet 60a that controls of grasping device 60 to control wire rod 11 then, and under the state that wire rod 11 is given prominence to from line mouth 51, by line mouth travel mechanism 52 this line mouth 51 is moved, the ora terminalis with this wire rod 11 shown in figure 11 inserts slit 70d.Make from this state-driven servomotor 75 and to hold line bobbin 70 and (for example slightly just changeing; About rotation 45 degree～90 degree); Hold the ora terminalis bending that line bobbin 70 will be inserted into the wire rod 11 among the slit 70d by what this was just changeing, make the end of this wire rod 11 be limited to this slit 70d thus.Like this, as shown in Figure 1 after the end with wire rod 11 is limited to slit 70d, grasping device 60 will be by the releasing of controlling of controlling wire rod 11 that sheet 60a carries out, thereby allows to derive wire rods 11 from wire rod exporter 50.Then, hold line bobbin 70 and further just change through making, the wire rod 11 that will after this derive from wire rod exporter 50 thus is wound in the rolling piece 70a between pair of flanges 70b, the 70c.And behind the wire rod 11 of ormal weight of having reeled, servomotor 75 is stopped, thereby stop to hold the just commentaries on classics of line bobbin 70.
< first holds line bobbin mobile process >
In this operation, the line bobbin 70 that holds that is installed on as the rotating shaft 75a of the servomotor 75 of drive source is fixed in and twines anchor clamps 21.Should fixing be undertaken, drive servomotor 27 this moment and make arm 72, and make first locking mechanism 73 that is installed on here shown in figure 10 with to hold line bobbin 70 mutually opposed with 23 rotations of first rotary body by connect mechanism 71.Utilize movable table travel mechanism 78 to make then to hold line bobbin 70 to move, thereby its coupled outside axle 70f is inserted into coupling aperture 73b and will holds line bobbin 70 and be installed on this first locking mechanism 73 with servomotor 75.
Then, make the bar 95a entering of behaviour's acting cylinder 95 and functional unit 76c is retreated, thereby second locking mechanism 76 is removed.Under this state, utilize movable table travel mechanism 78 to make servomotor 75 away from first locking mechanism 73.Utilize connect mechanism 71 to be fixed in winding anchor clamps 21 thus from the line bobbin 70 that holds that servomotor 75 breaks away from.At this moment, shown in figure 12, line mouth travel mechanism 52 so that the mode of the wire rod 11 that extends along the tangential direction of core 22 and core 22 quadratures to line mouth 51 location.Shown in figure 14 then, will be received into the groove 23a that is formed at first rotary body 23 to the wire rod 11 that holds 70 extensions of line bobbin from wire rod exporter 50.
< first coil forms operation >
In this operation, be rotated driving and will be wound in winding anchor clamps 21 with holding line bobbin 70 twining anchor clamps 21, thereby form first coil from the wire rod 11 that wire rod exporter 50 is derived.Particularly; Rotation synchronously drives servomotor 27,38; Shown in the solid arrow of Figure 15, make first and second rotary body with core 22 rotations, will be wound in by the core 22 of first and second rotary body 23,24 clampings from the wire rod 11 that wire rod exporter 50 is derived via line mouth 51.
When beginning to reel, then, this core 22 turns around and when reeling an astragal material 11 whenever revolving, and line mouth travel mechanism 52 just makes line mouth 51 axially only move the amount that directly equates with the line of this wire rod 11 along core 22.And variable spaced mechanism 41 is made as first and second rotary body 23, the length L (Fig. 8) of core 22 of wound skein product 11 between 24 than the line big slightly size in footpath of wire rod 11 at the coiling beginning initial stage and begins to reel; Turn around and when reeling an astragal material 11 whenever this core 22 revolves, just first and second rotary body 23, the length L of core 22 between 24 are only enlarged the amount that directly equates with the line of this wire rod 11.Thus, shown in figure 15, the mode that wire rod 11 can abut against each other with the length direction at core 22 is reeled.
In this execution mode, represented first coil 12 that radially be provided with multilayer of wire rod 11 along the coiling core 22 of the over-end winding curl of core 22.Therefore the wire rod 11 of the length through will having confirmed regulation in advance is wound in core 22, can obtain ground floor coiling 12a shown in Figure 15 thus.In the stage that obtains this ground floor coiling 12a, the length L of first and second rotary body 23, the core between 24 22 is than the coiling width, and it is slightly long promptly to multiply by the resulting length in line footpath than the number of turns of wire rod 11.After obtaining this ground floor coiling 12a; Return to the original length once more after utilizing variable spaced mechanism 41 that the length L of first and second rotary body 23, the core between 24 22 is temporarily shortened a little; Be wound in core 22 and axially compressing with aligning thus, thereby the wire rod 11 of ground floor coiling 12a is abutted against each other along the wire rod 11 of the axially-aligned of core 22 along core 22.And not shown heat blower heats so that the wire rod 11 mutual heat bondings that are adjacent to the wire rod 11 that is wound on the core 22 that twines anchor clamps 21.
Shown in figure 15, form the ground floor coiling when wire rod 11 is wound in core 22 after, then on this ground floor coiling 12a further wound skein product 11 as second layer coiling 12b.When the coiling of the wire rod 11 that reel to constitute this second layer coiling 12b, variable spaced mechanism 41 (Fig. 7) does not drive.That is, do not carry out the change of the length L (Fig. 7) of first and second rotary body 23, the core between 24 22.On the other hand; Shown in the solid arrow of Figure 16; When carrying out this second layer coiling 12b; Turn around and when reeling an astragal material 11 whenever this core 22 revolves, line mouth travel mechanism 52 (Fig. 7) just makes line mouth 51 only move the amount that directly equates with the line of this wire rod 11 to the opposite direction of moving direction when carrying out ground floor coiling 12a.When carrying out second layer coiling 12b, only wire rod 11 is wound in core 22 with the number of turns of stipulating then, thereby on ground floor coiling 12a, the whole coiling width that spreads all over this ground floor coiling 12 comes wound skein product 11.
Shown in figure 16, under the state of the wire rod 11 of the ormal weight of the formation second layer coiling 12b that on ground floor winds the line 12a, fitly reeled, this second layer coiling 12b is finished.Like this; After second layer coiling is accomplished; Temporarily utilize variable spaced mechanism 41 (Fig. 7) to make the length L of first and second rotary body 23, the core between 24 22 shorten the back a little once more and return to the original length once more, the wire rod 11 that constitutes this second layer coiling 12b is abutted against each other.Carry out such action and on second layer coiling 12b, form the 3rd layer of later coiling successively through alternate repetition, shown in figure 17ly thus can access first coil 12 with expection number of plies.
Like this, in the present invention, utilize connect mechanism 71 will hold line bobbin 70 and be fixed in the winding anchor clamps, winding anchor clamps 21 are held line bobbin 70 with this be rotated driving.And owing to the wire rod 11 of deriving from wire rod exporter 50 of reeling forms first coil 12, therefore twine the rotation number of anchor clamps 21, just can freely adjust the number of turns of this first coil 12 through changing adjustment.
In the forming process of this first coil 12, in wire rod exporter 50, give constant tension force to the wire rod 11 of deriving from wire rod exporter 50.As shown in Figure 6, the tensioning apparatus of giving by wire rod exporter 50 53 of this tension force carries out, and in this tensioning apparatus 53, utilizes spring 66 and gives tension force via 63 pairs of wire rods 11 of nutted rod.Therefore in the process that forms this first coil 12, the tension force of wire rod 11 is remained the value of regulation, thereby the tightening degree of interlayer that can prevent the wire rod 11 of first coil 12 produces difference.
In addition; After obtaining first coil 12; Shown in figure 13, utilize the sheet 60a that controls of grasping device 60 to control wire rod 11, and preventing from the basis of wire rod exporter 50 derivation wire rods 11; Utilize cylinder 59a that cutter sweep 59 (Fig. 6) is moved to off-position, thereby will cut off to the wire rod 11 that wire rod exporter 50 extends from this first coil 12.Thus, shown in Figure 19 (a), can access first coil 12 that the leading part 15 that is made up of this wire rod begins to extend diametrically from periphery.
< second holds line bobbin mobile process >
In this operation, make and hold line bobbin 70 from twining anchor clamps 21 disengagings, this is held line bobbin 70 be installed on rotating shaft 75a as the servomotor 75 of drive source.Particularly, at first drive servomotor 27 and make arm 72 with the rotation of first rotary body 23, and make install via first locking mechanism 73 to hold line bobbin 70 shown in figure 10 opposed with servomotor 75.Make the bar 95a of behaviour's acting cylinder 95 as the solid line arrow is represented, get into and second locking mechanism 76 is removed then; Under this state, utilize movable table travel mechanism 78 that servomotor 75 is moved, make the inner couplings axle 70e that holds line bobbin 70 embed the coupling aperture 76b of second locking mechanism 76.Then, shown in dotted arrow, make the bar 95a of behaviour's acting cylinder 95 outstanding, and this is held the rotating shaft 75a that line bobbin 70 is installed on servomotor 75 by second locking mechanism 76.Under this state, utilize movable table travel mechanism 78 to make servomotor 75, hold line bobbin 70 from twining anchor clamps 31 disengagings thereby make away from first locking mechanism 73.Then, shown in figure 13, so that will hold line bobbin 70 location to the wire rod 11 that holds 70 extensions of line bobbin and the mode of core 22 quadratures from first coil 12.
< second coil forms operation >
In this operation, rotation drive to be twined anchor clamps 21 and is reeled from holding the wire rod 11 that line bobbin 70 is derived, thereby forms second coil 13.When carrying out this coiling; Shown in the solid arrow of Figure 18; Make core 22 from first rotary body, the 23 outstanding bigger amounts in line footpath that are equivalent to than wire rod 11 by moving machine 31; Meanwhile, variable spaced mechanism 41 enlarges first and second rotary body 23, the length L of core 22 between 24, makes its line footpath than wire rod 11 bigger.Like this, between first coil 12 that constitutes by the wire rod that is wound in this core 22 11 and first rotary body 23, produce bigger gap, line footpath than wire rod 11.The wire rod 11 that is contained in groove 23a is broken away from from this groove 23a.
Rotation drives servomotor 27,38 synchronously then; Shown in the dotted arrow of Figure 18; Make first and second rotary body with core 22 to direction rotation opposite when forming first coil 12, will be wound in from the wire rod 11 that holds line bobbin 70 and derive on the core 22 adjacent with first coil 12.At this moment, movable table travel mechanism 78 does not drive, thereby movable table 77 is moved.Then will line bobbin 70 unclamps and the wire rod 11 of deriving is wound in the core 22 between this first coil 12 and first rotary body 23 from holding.Wherein, The 70b of pair of flanges portion, the 70c that holds line bobbin 70 separates than the slightly wide gap 70n (Figure 10) in the line footpath of wire rod 11 and opposed each other; Because wire rod 11 is wound in rolling piece 70a therebetween, therefore from this wire rod that holds 70 derivation of line bobbin the axial situation of holding line bobbin 70 can not appear departing from.Therefore from holding that line bobbin 70 unclamps and the wire rod 11 of deriving correctly is directed to the part with the core 22 of this wire rod 11 quadratures; Promptly be directed to the core 22 between first coil 12 and first rotary body 23; And be wound in this core 22, thereby form second coil 13.
In forming the process of this second coil 13, make holding line bobbin 70 and move after twine anchor clamps 21 and take off with respect to twining anchor clamps 21, thereby to giving constant tension force from the wire rod 11 that holds line bobbin 70 and derive.In this execution mode, hold the moving of line bobbin 70 by holding the fluid-pressure cylinder 92 that line bobbin 70 leaves the direction application of force of twining anchor clamps 21 and carry out to making.That is, the sliding part 93a that the restriction shown in Fig. 5 is moved with cylinder 93 restores as the solid line arrow is represented, thereby the snap-latch piece 93c that is arranged at is here broken away from from the second projection 92c.Sliding part 92a in the fluid-pressure cylinder 92 that is provided with servomotor 75 is moved.On the other hand, the servomotor 75 as drive source is stopped, line bobbin 70 rotates with its rotating shaft 75a and again wire rod 11 is derived thereby forbid holding.And this fluid-pressure cylinder 92 supplied with the fluid of authorized pressures; In this execution mode; Be to supply with the compressed air be adjusted to authorized pressure, shown in the dotted arrow of Fig. 2, to hold line bobbin 70 self with this sliding part 92a to away from the direction application of force of twining anchor clamps 21.Thus to line bobbin 70 extends and the wire rod 11 that is wound in core 22 is given constant tension force from holding.
Like this, make and hold line bobbin 70 and move, and give constant tension force, can not make the tension force change of giving wire rod 11 thus the wire rod 11 that holds line bobbin 70 from this and derive to leaving the direction of twining anchor clamps 21.That is be not to utilize the back tension that makes when holding 70 rotations of line bobbin to give constant tension force in the present invention, to wire rod 11.In the present invention, not to make to hold line bobbin 70 rotation, but this is held line bobbin 70 self to leaving the direction application of force of twining anchor clamps 21, give constant tension force to the wire rod 11 that holds line bobbin 70 from this and derive thus with constant power.Therefore unclamp and derive and reduced even will accumulate, also can not make the tension force change of giving wire rod 11 by being wound in the external diameter that this wire rod that holds line bobbin 70 11 constitutes in this wire rod 11 that holds line bobbin 70.Therefore, even in the process that forms this second coil 13, the tension force of wire rod 11 also can be retained as the value of regulation, thereby avoids the tightening degree of the wire rod 11 of second coil 13 to produce difference, therefore can improve the occupation efficiency of the wire rod 11 that forms coil 10.And hold line bobbin 70 and carry out therefore just can easily adjusting the tension force of giving wire rod 11 through adjusting this fluid pressure to holding line bobbin 70 application of forces to leaving the fluid-pressure cylinder 92 that the direction of twining anchor clamps 21 moves owing to utilize to make.
On the other hand, hold line bobbin 70 rotation and when wire rod 11 is wound in core 22 when not making, then hold active force that line bobbin 70 can opposing fluid-pressure cylinders 92 and with sliding part 92a near core 22.As shown in Figure 3 then, sliding part 92a makes the projection 92d that wins mutually opposed with proximity transducer 97 near twining anchor clamps 21.Detect when holding line bobbin 70 when proximity transducer 97 so near core 22; Hold line bobbin 70 and as the solid line arrow is represented, reverse thereby then not shown controller drives makes as the servomotor 75 of drive source, and the wire rod 11 that will Duo than the amount that is wound in core 22 hold that line bobbin 70 unclamps and derive again from this with its rotating shaft 75a.Hold that line bobbin 70 reverses and when deriving wire rod 11 when making like this, then hold line bobbin 70 by the active force of fluid-pressure cylinder 92 and mobile with sliding part 92a as the solid arrow of Fig. 3 is represented, thereby leave core 22.Even when deriving this new wire rod 11,, therefore can give and keep constant tension force the wire rod 11 that holds line bobbin 70 from this and derive because fluid-pressure cylinder 92 holds line bobbin 70 to leaving the direction application of force of twining anchor clamps 21 with constant power to what reverse.
When deriving again when holding that line bobbin 70 reverses and with wire rod 11, then above-mentioned sliding part 92a twines anchor clamps 21 because of the active force of fluid-pressure cylinder 92 leaves gradually, and is as shown in Figure 2 then, makes the first projection 92d mutually opposed with separation sensor 98.So separation sensor 98 detects and holds line bobbin 70 and left core 22, not shown controller makes the servomotor 75 as drive source stop once more, thereby stops once more deriving wire rods 11 from holding line bobbin 70.Through carrying out such action repeatedly from holding line bobbin 70 derivation wire rods 11 and stopping to derive; Even hold line bobbin 70 thereby will be wound in above the wire rod 11 of proximity transducer 97 and the length at the interval of separation sensor 98; Also can derive this wire rod 11 successively in that the wire rod 11 of being derived is given under the state of constant tension force.And because drive source is a servomotor 75; And hold the rotating shaft 75a of line bobbin 70 dismounting freely in servomotor 75; Therefore hold line bobbin 70 and just changeing and reels as making, also can use this servomotor 75 from the drive source of the wire rod 11 of wire rod exporter 50 derivation.Therefore can save and be provided for the wire rod 11 of deriving from wire rod exporter 50 is wound in other the drive source that holds line bobbin 70.
