Turn back to Fig. 1, movable table 77 is can be arranged at pallet 19 along the mode of three direction of principal axis movements.This movable table 77 is arranged at pallet 19 via movable table travel mechanism 78, and the movable table travel mechanism 78 of present embodiment is combined by X-axis, Y-axis and Z-direction expansion actuator 79 ~ 81 and forms.Because this movable table travel mechanism 78 and aforesaid Xian Zui travel mechanism 52 are same structure, therefore the repetitive description thereof will be omitted.
As shown in Figures 4 and 5, this movable table 77 is provided with tension applying device 91, this tension applying device 91 by make from be wound around fixture 21 take off after the line bobbin 70 that stores move relative to this winding fixture 21, thus to from this store line bobbin 70 derive wire rod 11 give constant tension force.Tension applying device 91 in present embodiment possesses fluid-pressure cylinder 92, and this fluid-pressure cylinder 92 is arranged at movable table 77 and makes to store line bobbin 70 and moves to leaving the direction being wound around fixture 21.Fluid-pressure cylinder 92 has: extend along X-direction and be in fact installed on the cylinder main body 92b of movable table 77 and utilize and supply the fluid pressure and the sliding part 92a that can reciprocate in the X-axis direction along this cylinder main body 92b of discharging to this cylinder main body 92b.And be installed on this sliding part 92a as the servomotor of drive source 75.This servomotor 75 is installed on sliding part 92a via mounting panel 94, on this mounting panel 94, behaviour's acting cylinder 95 is also provided with, for second locking mechanism (Figure 10) of operation setting in the rotating shaft 75a (Figure 10) of this servomotor 75 except servomotor 75.
As shown in Figure 10, the engaging part 96 engaged with the functional unit 76c of the second locking mechanism 76 is installed on to be grasped on the bar 95a of acting cylinder 95.And be configured to: when this behaviour's acting cylinder 95 makes this bar 95a enter as shown in solid arrow, then functional unit 76c resists the active force of spring 76d and retreats, thus inner couplings axle 70e can be inserted the coupling aperture 76b on cylindrical shell 76a.And be configured to: when making bar 95a give prominence to as the dotted line arrows under the state that inner couplings axle 70e is inserted into coupling aperture 76b, then functional unit 76c again advances Lock Part is pressed on endless groove 70g, and the axle 70e that is coupled thus can not depart from from this coupling aperture 76b.
On the other hand, be configured to: under the state that inner couplings axle 70e is inserted into coupling aperture 76b, when grasping acting cylinder 95 and making this bar 95a again enter as shown in solid arrow, then the inner couplings axle 70e inserted can be extracted from this coupling aperture 76b.Be configured to like this: store line bobbin 70 by this second locking mechanism 76 can dismounting in the rotating shaft 75a of the servomotor 75 as drive source.What link with the rotating shaft 75a of servomotor 75 stores line bobbin 70 and can carry out around Y-axis the both sides that rotate forward and reverse by this servomotor 75.And this is stored line bobbin 70 and is accumulated by the wire rod 11 just transferring winding and derive from wire rod exporter 50, after accumulation wire rod, unclamp by carrying out reversing the wire rod 11 be wound and wire rod 11 is stored line bobbin 70 derive from this.
As shown in Figures 4 and 5, fluid-pressure cylinder 92 is the sliding part 92a that makes to be provided with this servomotor 75 parts along X-direction movement.Therefore storing under the state of rotating shaft 75a (Figure 10) that line bobbin 70 is installed on servomotor 75, when this servomotor 75 moves to the direction leaving winding fixture 21, then store line bobbin 70 also to move to leaving the direction being wound around fixture, thus give constant tension force to the wire rod 11 storing line bobbin 70 derivation from this.In addition, do not drive servomotor 75 when giving this tension force, thus can not make to store line bobbin 70 and rotate.
Further, movable table 77 is arranged: proximity transducer 97, it detects this sliding part 92a close to the situation being wound around fixture 21; Separation sensor 98, it detects this sliding part 92a from the situation that winding fixture 21 leaves.Each transducer 97,98 is the transducers exporting connection signal when opposed with the first projection 92d being arranged at sliding part 92a, as shown in Figure 3, arranging proximity transducer 97 with sliding part 92a close to the position that the first projection 92d when being wound around fixture 21 is opposite, as shown in Figure 2, arranging separation sensor 98 with this sliding part 92a from the position that the first projection 92d be wound around when fixture 21 leaves is opposite.The detection of each transducer 97,98 exports and is connected with the control device of the servomotor 75 as drive source that is not shown controller.And this controller is configured to: as shown in Figure 3 when proximity transducer 97 exports connection signal because storing line bobbin 70 close to being wound around fixture 21, then drive servomotor 75, as shown in Figure 2 when separation sensor 98 because of store line bobbin 70 leave be wound around fixture 21 and export connection signal time, then make the servomotor 75 carrying out driving stop.Controlling servomotor 75 in like fashion by controller, thus when storing line bobbin 70 close to when being wound around fixture 21, then deriving wire rod 11 from storing line bobbin 70, when storing line bobbin 70 and leaving winding fixture 21, forbidding deriving wire rod 11 from storing line bobbin 70.
Further, this movable table 77 also arranges moving-limiting cylinder 93, the movement of the sliding part 92a in fluid-pressure cylinder 92 can be forbidden or allow to this moving-limiting cylinder 93.This moving-limiting cylinder 93 is arranged at movable table 77 with extending in the mode orthogonal with fluid-pressure cylinder 92 along Z-direction.On the other hand, as shown in Figure 4 when storing line bobbin 70 and leaving winding fixture 21, in the face of the second projection 92c of moving-limiting cylinder 93 is installed on the sliding part 92a of fluid-pressure cylinder 92.The sliding part 93a of moving-limiting cylinder 93 is provided with snap-latch piece 93c, and this snap-latch piece 93c engages with the second projection 92c according to the presence or absence of fluid pressure supply or departs from from this second projection 92c.And be configured to: make when the main body 93b delivering fluids to moving-limiting cylinder 93 sliding part 93a as shown in the solid arrow of Fig. 4 movement, when the snap-latch piece 93c be arranged at herein is engaged with the second projection 92c, then forbid the movement of the sliding part 92a of fluid-pressure cylinder 92, and when the supply of fluid stops sliding part 93a as shown in the dotted arrow of Fig. 4 restore thus snap-latch piece 93c is departed from from the second projection 92c time, then allow the movement of the sliding part 92a of fluid-pressure cylinder 92.
In addition, although not shown, the heat blower of its heat bonding is made to be arranged at pallet 19 by heating the wire rod 11 be wound on the core 22 being wound around fixture 21.
Next, the method for winding of the present invention employing above-mentioned Winder is described.
Method for winding of the present invention is following method: be wound in by the wire rod 11 of deriving from wire rod exporter 50 and store line bobbin 70, winding fixture 21 is stored together with line bobbin 70 with this and carries out rotary actuation, the wire rod 11 of deriving from wire rod exporter 50 is wound in and is wound around fixture 21 and after forming the first coil 12, by store line bobbin 70 from be wound around fixture 21 take off after state rotary actuation be wound around fixture 21, by the wire rod 11 of deriving is wound in and is wound around fixture 21 from storing that line bobbin 70 unclamps, thus form the second coil 13.Below, each operation is described in detail.
< stores line procedures >
In this operation, the wire rod 11 of deriving from wire rod exporter 50 is wound in and stores line bobbin 70.This winding is undertaken by drive source 75, stores line bobbin 70 is installed on the servomotor 75 as drive source in not revolvable mode rotating shaft 75a by the second locking mechanism 76.This is fitted through and carries out with under type: the bar 95a of the behaviour's acting cylinder 95 shown in Figure 10 is entered as represented in solid arrow, functional unit 76 is made to resist the active force of spring 76d and retreat, and in this condition inner couplings axle 70e is inserted coupling aperture 76b, then make bar 95a outstanding as represented in dotted arrow.Now utilize the moving-limiting cylinder 93 shown in Fig. 4 that this snap-latch piece 93c is engaged with the second projection 92c, forbidding the movement of the sliding part 92a of the fluid-pressure cylinder 92 being provided with servomotor 75, can forbid the useless movement of servomotor 75, is therefore preferred.
And drive servomotor 75 that its rotating shaft 75a is rotated with storing together with line bobbin 70, the wire rod 11 of deriving from wire rod exporter 50 is wound in stores line bobbin 70 thus.Its detailed order is: first cutter sweep 59 is remained on position of readiness.Then utilize the holding sheet 60a of grasping device 60 to hold wire rod 11, and making to make this line mouth 51 move by Xian Zui travel mechanism 52 wire rod 11 state outstanding from line mouth 51, as shown in figure 11 the ora terminalis of this wire rod 11 is inserted slit 70d.Make to store line bobbin 70 from this state-driven servomotor 75 slightly to rotate forward (such as, rotate 45 degree ~ about 90 degree), store by this rotating forward the ora terminalis bending of wire rod 11 that line bobbin 70 will be inserted in slit 70d, make the end of this wire rod 11 be locked to this slit 70d thus.Like this, after the end of wire rod 11 is locked to slit 70d, as shown in Figure 1, grasping device 60 is removed by the holding holding the wire rod 11 that sheet 60a carries out, thus allows to derive wire rod 11 from wire rod exporter 50.Then, rotating forward further by making to store line bobbin 70, thus the wire rod 11 of after this deriving from wire rod exporter 50 being wound in the rolling piece 70a between pair of flanges 70b, 70c.And after the wire rod 11 of ormal weight that reeled, servomotor 75 is stopped, thus stop the rotating forward storing line bobbin 70.
< first stores line bobbin mobile process >
In this operation, the line bobbin 70 that stores of the rotating shaft 75a of the servomotor 75 be installed on as drive source is fixed on winding fixture 21.This is fixing is undertaken by connect mechanism 71, now drives servomotor 27 that arm 72 is rotated together with the first rotary body 23, and makes the first locking mechanism 73 of being installed on herein opposite with storing line bobbin 70 as shown in Figure 10.Then utilize movable table travel mechanism 78 to make to store line bobbin 70 to move together with servomotor 75, thus its coupled outside axle 70f is inserted into coupling aperture 73b and line bobbin 70 will be stored and be installed on this first locking mechanism 73.
Then, make the bar 95a of behaviour's acting cylinder 95 enter and functional unit 76c is retreated, thus the second locking mechanism 76 is removed.Movable table travel mechanism 78 is utilized to make servomotor 75 away from the first locking mechanism 73 in this condition.Utilize connect mechanism 71 that the line bobbin 70 that stores departed from from servomotor 75 is fixed on winding fixture 21 thus.Now, as shown in figure 12, the mode that the wire rod 11 that extends with the tangential direction made along core 22 of Xian Zui travel mechanism 52 is orthogonal with core 22 is located line mouth 51.Then as shown in figure 14, be received into from wire rod exporter 50 in the groove 23a being formed at the first rotary body 23 to storing the wire rod 11 that line bobbin 70 extends.
< First Line circle formation process >
In this operation, carry out rotary actuation and the wire rod 11 of deriving from wire rod exporter 50 be wound in being wound around fixture 21 with storing together with line bobbin 70 to winding fixture 21, thus formation the first coil.Specifically, synchronous rotary drives servomotor 27,38, as shown in the solid arrow of Figure 15, make first and second rotary body rotate together with core 22, the core 22 clamped by first and second rotary body 23,24 will be wound in via the wire rod 11 that line mouth 51 is derived from wire rod exporter 50.
When starting to reel, then whenever this core 22 revolve turn around and reel an astragal material 11 time, Xian Zui travel mechanism 52 just makes line mouth 51 along axially only mobile equal with the wire diameter of this wire rod 11 amount of core 22.And the length L (Fig. 8) of the core 22 of the wound skein product 11 between first and second rotary body 23,24 is set to the size slightly larger than the wire diameter of wire rod 11 at the winding beginning initial stage and starts winding by variable spaced mechanism 41, whenever this core 22 revolve turn around and reel an astragal material 11 time, just the length L of the core 22 between first and second rotary body 23,24 is only expanded the amount equal with the wire diameter of this wire rod 11.Thus, as shown in figure 15, wire rod 11 can reel in the mode abutted against each other at the length direction of core 22.
In the present embodiment, the first coil 12 that the coiling of wire rod 11 along the over-end winding curl of core 22 is provided with multilayer in the radial direction of core 22 is illustrated.Therefore by the wire rod 11 of the length being previously determined regulation is wound in core 22, the ground floor coiling 12a shown in Figure 15 can be obtained thus.Obtaining the stage of this ground floor coiling 12a, the length L of the core 22 between first and second rotary body 23,24, than coiling width, is namely multiplied by than the number of turns of wire rod 11 length that wire diameter obtains slightly long.After this ground floor coiling of acquisition 12a, again the original length is returned to after utilizing variable spaced mechanism 41 that the length L of the core 22 between first and second rotary body 23,24 is temporarily shortened a little, be wound in core 22 with aligning thus and wire rod 11 along the axially-aligned of core 22 compresses along the axis of core 22, thus the wire rod 11 of ground floor coiling 12a is abutted against each other.And the mutual heat bonding of wire rod 11 that not shown heat blower heats to make to be adjacent to the wire rod 11 be wound on the core 22 being wound around fixture 21.
As shown in figure 15, when wire rod 11 being wound in core 22 after forming ground floor coiling, then on this ground floor coiling 12a further wound skein product 11 as second layer coiling 12b.When reeling the winding of the wire rod 11 forming this second layer coiling 12b, variable spaced mechanism 41 (Fig. 7) does not drive.That is, the change of the length L (Fig. 7) of the core 22 between first and second rotary body 23,24 is not carried out.On the other hand, as shown in the solid arrow of Figure 16, when carrying out this second layer coiling 12b, whenever this core 22 revolve turn around and reel an astragal material 11 time, Xian Zui travel mechanism 52 (Fig. 7) just make line mouth 51 to the direction contrary with moving direction when carrying out ground floor coiling 12a the only mobile amount equal with the wire diameter of this wire rod 11.Then, when carrying out second layer coiling 12b, only wire rod 11 is wound in core 22 with the number of turns of regulation, thus on ground floor coiling 12a, the whole coiling width spreading all over this ground floor coiling 12 carrys out wound skein product 11.
As shown in figure 16, under the state of the wire rod 11 of the ormal weight forming second layer coiling 12b that ground floor coiling 12a has fitly reeled, this second layer coiling 12b is terminated.Like this, after second layer coiling completes, again return to the original length after temporarily utilizing variable spaced mechanism 41 (Fig. 7) again to make the length L of the core 22 between first and second rotary body 23,24 shorten a little, the wire rod 11 of this second layer coiling of formation 12b can be made thus to abut against each other.Carry out such action by alternate repetition and the coiling that formed successively on second layer coiling 12b after third layer, first coil 12 with the expection number of plies can be obtained thus as shown in figure 17.
Like this, in the present invention, utilize connect mechanism 71 will store line bobbin 70 and be fixed on winding fixture, winding fixture 21 is stored together with line bobbin 70 with this and carries out rotary actuation.And because winding forms the first coil 12 from the wire rod 11 of wire rod exporter 50 derivation, being therefore wound around the rotation number of fixture 21 by changing adjustment, just freely can adjusting the number of turns of this first coil 12.
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 imparting of this tension force is undertaken by the tensioning apparatus 53 of wire rod exporter 50, in this tensioning apparatus 53, utilizes spring 66 and gives tension force via nutted rod 63 pairs of wire rods 11.Therefore in the process forming this first coil 12, the tension force of wire rod 11 is remained the value of regulation, thus can prevent the tightening degree of the interlayer of the wire rod 11 of the first coil 12 from producing difference.
In addition, after acquisition first coil 12, as shown in figure 13, utilize the holding sheet 60a of grasping device 60 to hold wire rod 11, and preventing from deriving the basis of wire rod 11 from wire rod exporter 50, utilize cylinder 59a that cutter sweep 59 (Fig. 6) is moved to off-position, thus the wire rod 11 extended from this first coil 12 to wire rod exporter 50 is cut off.Thus, as shown in Figure 19 (a), the first coil 12 that the leading part 15 that can obtain being made up of this wire rod extends diametrically from periphery.
< second stores line bobbin mobile process >
In this operation, make to store line bobbin 70 and depart from from winding fixture 21, this is stored the rotating shaft 75a that line bobbin 70 is installed on the servomotor 75 as drive source.Specifically, first drive servomotor 27 and arm 72 is rotated together with the first rotary body 23, and make to install via the first locking mechanism 73 to store line bobbin 70 opposed with servomotor 75 as shown in Figure 10.Then the bar 95a of behaviour's acting cylinder 95 is made to enter as represented in solid arrow and be removed by the second locking mechanism 76, utilize movable table travel mechanism 78 that servomotor 75 is moved in this condition, make the inner couplings axle 70e storing line bobbin 70 embed the coupling aperture 76b of the second locking mechanism 76.Then, make the bar 95a of behaviour's acting cylinder 95 give prominence to as the dotted line arrows, and by the second locking mechanism 76, this is stored the rotating shaft 75a that line bobbin 70 is installed on servomotor 75.Utilize movable table travel mechanism 78 to make servomotor 75 away from the first locking mechanism 73 in this condition, thus make to store line bobbin 70 and depart from from winding fixture 31.Then, as shown in figure 13, locate to make will to store line bobbin 70 from the mode that the first coil 12 is orthogonal with core 22 to the wire rod 11 storing line bobbin 70 extension.
< second coil formation process >
In this operation, rotary actuation is wound around fixture 21 and reels from the wire rod 11 storing line bobbin 70 derivation, thus forms the second coil 13.When carrying out this winding, as shown in the solid arrow of Figure 18, core 22 is made to be equivalent to the amount more bigger than the wire diameter of wire rod 11 from the first rotary body 23 is outstanding by moving machine 31, meanwhile, the length L of the core 22 between first and second rotary body 23,24 expands by variable spaced mechanism 41, makes it more bigger than the wire diameter of wire rod 11.Like this, between the first coil 12 be made up of the wire rod 11 being wound in this core 22 and the first rotary body 23, the gap more bigger than the wire diameter of wire rod 11 is produced.Then the wire rod 11 being contained in groove 23a is made to depart from from this groove 23a.
Then synchronous rotary drives servomotor 27,38, as shown in the dotted arrow of Figure 18, first and second rotary body and core 22 are rotated to the direction contrary with during formation the first coil 12 together, is wound in from the wire rod 11 storing line bobbin 70 and derive on the core 22 adjacent with the first coil 12.Now, movable table travel mechanism 78 does not drive, thus movable table 77 can not be made to move.Then to unclamp from storing line bobbin 70 and the wire rod 11 of deriving is wound in core 22 between this first coil 12 and first rotary body 23.Wherein, pair of flanges portion 70b, 70c of storing line bobbin 70 separate the gap 70n (Figure 10) slightly wider than the wire diameter of wire rod 11 and mutually opposing, because wire rod 11 is wound in rolling piece 70a therebetween, the wire rod therefore storing line bobbin 70 derivation from this there will not be the situation departing from the axis storing line bobbin 70.Therefore to unclamp and the wire rod 11 of deriving is properly directed to the part of the core 22 orthogonal with this wire rod 11 from storing line bobbin 70, namely the core 22 between the first coil 12 and the first rotary body 23 is directed to, and be wound in this core 22, thus form the second coil 13.
In the process forming this second coil 13, the line bobbin 70 that stores after taking off is moved relative to winding fixture 21, thus give constant tension force to from the wire rod 11 storing line bobbin 70 derivation from winding fixture 21.In the present embodiment, the movement storing line bobbin 70 is undertaken by the fluid-pressure cylinder 92 making to store line bobbin 70 and leave the direction force being wound around fixture 21.That is, make the sliding part 93a of cylinder 93 of the moving-limiting shown in Fig. 5 restore as represented in solid arrow, thus the snap-latch piece 93c be arranged at herein is departed from from the second projection 92c.The sliding part 92a be provided with in the fluid-pressure cylinder 92 of servomotor 75 can be made thus to move.On the other hand, the servomotor 75 as drive source is stopped, thus forbid that store line bobbin 70 rotates and again derived by wire rod 11 together with its rotating shaft 75a.And this fluid-pressure cylinder 92 is supplied to the fluid of authorized pressure, in the present embodiment, being the compressed air that supply is adjusted to authorized pressure, as shown in the dotted arrow of Fig. 2, exerting a force to away from the direction being wound around fixture 21 together with this sliding part 92a to storing line bobbin 70 self.To extend and constant tension force given by the wire rod 11 being wound in core 22 from storing line bobbin 70 thus.
Like this, make to store line bobbin 70 and move to leaving the direction being wound around fixture 21, and give constant tension force to the wire rod 11 storing line bobbin 70 derivation from this, the tension force change of imparting wire rod 11 can not be made thus.That is, also non-used makes the back tension stored when line bobbin 70 rotates give constant tension force to wire rod 11 in the present invention.In the present invention, not make to store line bobbin 70 to rotate, but with constant power, line bobbin 70 self is stored to leaving the direction force being wound around fixture 21 to this, give constant tension force to the wire rod 11 storing line bobbin 70 derivation from this thus.Even if therefore unclamp accumulating the wire rod 11 storing line bobbin 70 in this and derive and reduce by the external diameter being wound in this wire rod 11 storing line bobbin 70 and forming, the tension force change of imparting wire rod 11 also can not be made.Therefore, even if in the process forming this second coil 13, the tension force of wire rod 11 also can be retained as the value of regulation, thus avoids the tightening degree of the wire rod 11 of the second coil 13 to produce difference, therefore, it is possible to improve the occupation efficiency of the wire rod 11 forming coil 10.And carrying out exerting a force to storing line bobbin 70 to the fluid-pressure cylinder 92 leaving the direction movement being wound around fixture 21 because utilization makes to store line bobbin 70, therefore just easily can adjust by this fluid pressure of adjustment the tension force giving wire rod 11.
On the other hand, when not making to store line bobbin 70 and rotating and wire rod 11 is wound in core 22, then store line bobbin 70 can resist fluid-pressure cylinder 92 active force and close to core 22 together with sliding part 92a.Then as shown in Figure 3, sliding part 92a, close to being wound around fixture 21, makes the first projection 92d opposite with proximity transducer 97.Like this when proximity transducer 97 detect store line bobbin 70 close to core 22 time, then not shown controller drives the servomotor 75 as drive source thus makes to store line bobbin 70 and reverses as represented in solid arrow together with its rotating shaft 75a, and the wire rod 11 more than the amount being wound in core 22 is stored line bobbin 70 and unclamp from this and again derive.When making to store line bobbin 70 like this and reversing and derive wire rod 11, then store line bobbin 70 by the active force of fluid-pressure cylinder 92 moves as represented in the solid arrow of Fig. 3 together with sliding part 92a, thus leaves core 22.Even if when deriving this new wire rod 11, because fluid-pressure cylinder 92 stores line bobbin 70 to leaving the direction force being wound around fixture 21, therefore, it is possible to give the wire rod 11 storing line bobbin 70 derivation from this and keep constant tension force with constant power to what reverse.
When again being derived by wire rod 11 when storing line bobbin 70 and reversing, then above-mentioned sliding part 92a leaves gradually because of the active force of fluid-pressure cylinder 92 and is wound around fixture 21, then as shown in Figure 2, makes the first projection 92d opposite with separation sensor 98.So separation sensor 98 detects that storing line bobbin 70 has left core 22, not shown controller makes to stop as the servomotor 75 of drive source again, thus again stops deriving wire rod 11 from storing line bobbin 70.By repeatedly carrying out such derive wire rod 11 from storing line bobbin 70 and stop the action of derivation, even if thus the wire rod 11 exceeding the length at the interval of proximity transducer 97 and separation sensor 98 be wound in store line bobbin 70, also under the state of giving constant tension force to the wire rod 11 be exported, this wire rod 11 can be derived successively.And due to drive source be servomotor 75, and store line bobbin 70 dismounting freely in the rotating shaft 75a of servomotor 75, therefore rotate forward as making to store line bobbin 70 and reel from the drive source of the wire rod 11 of wire rod exporter 50 derivation, also can use this servomotor 75.Arrange for the wire rod of deriving from wire rod exporter 50 11 being wound in other the drive source storing line bobbin 70 therefore, it is possible to save.
