Embodiment

Fig. 1 is the right side view of showing in the partial cutaway of an embodiment of automatic coil winding machine of the present invention, and Fig. 2 is the front view of its major part.Among the figure, the 10th, utilize the bobbin of the coil that this automatic coil winding machine winds the line, on two opposite sides of the end of bobbin 10, a plurality of binding posts 12 in single file are installed respectively.In bobbin 10, be formed with the flange 16 shown in the dotted line among incorporate cylinder coiling position 14 and the figure.Flange 16 is clamped on the chuck 20 that rotates around the trunnion axis center of can doing, thereby bobbin 10 is supported.Doing on the nozzle holder 30 that horizontal direction and above-below direction that is three-dimensional move, be fixed with the directional nozzle 32 and the cylinder 35 that are provided with the wire rod supply hole.The 40th, the moving slider that is connected with the piston 38 (Fig. 2) of cylinder 35.And, omitted piston 38 among Fig. 1.

In order to utilize this automatic coil winding machine wound skein product 5 on bobbin 10, at first make directional nozzle 32 rotate several weeks around binding post 12, wire rod 5 is wound on binding post 12.Then, directional nozzle 32 being moved on to the top at the coiling position 14 of bobbin 10, is center high speed rotary chuck 20 with the horizontal direction axle afterwards, at coiling position 14 wound wires 5.At this moment, at the axially mobile guide nozzle 32 inchmeal of bobbin 10.

In moving slider 40, fixed outer nozzle 60 with through hole 62, and make directional nozzle 32 insert through hole 62, utilize the driving of 35 pairs of moving sliders 40 of cylinder, it is moved at illustrated above-below direction with respect to nozzle holder 30, when moving slider 40 is in the top position, the front end of directional nozzle 32 is outstanding from the diagram lower ends downward of outer nozzle 60, and when being in lower position, the front end of directional nozzle 32 is also upwards withdrawn from the lower end of outer nozzle 60.In order not make the wire rod of carrying from the front end of directional nozzle 32 5 injured, make the directional nozzle 32 that contact with wire rod 5 and the lower end formation fillet of outer nozzle 60.

As shown in Figure 2, on moving slider 40 also by Screw 52 rotatable supportings be equipped with the rotation pull 50, thus, connect the direction of arrow by spring 54 and rotation is pulled 50 bestow revolving force, rotation pull 50 be installed on the moving slider 40 block 42 collisions and by stop.Be formed with downward thrust 44 on moving slider 40, the protruding part forms recess 46 with the bottom of swivel plate 50 at the downside of moving slider 40 thus.Constitute a side 47 of recess 46 and under the effect of spring 54, make the interior side direction of side 47 oriented recesses 46 lean trend by being limited to the rotation swivel plate 50 that can rotate in the certain limit.

Return Fig. 1 again and illustrate, the 70th, be used for fixing the tension disk of wire rod 5.Tension disk 70 comprises cylindrical shell 72 and have the compressing member 74 of the axle that connects in cylindrical shell 72, wire rod 5 is clamped between the compressing member 74 and cylindrical shell 72 that can move up and down.Because moving slider 40 is supported on the nozzle holder 30, so can move in all directions with nozzle holder 30.Tightening the cut-out of the wire rod 5 that frame crosses between binding post 12 and tension disk 70, is like that moving slider 40 to be moved near the bobbin 10 as described below, carries out under by Fig. 1 state among the recess 46 at wire rod 5.Like this, pin 80 is set, when making it among wire rod 5 passes through recess 46, wire rod 5 is pressed to from side direction in the position between moving slider 40 and tension disk 70.

Fig. 3 is the view of the automatic coil winding machine of Fig. 1 state of looking down from the top.Pin 80 is fixed on by spring 82 and pushes to by the power of spring 82 wire rod 5 flexibly be pushed down on the pin pressure pin 84 of a side.The direction that pin 80 is pushed to by spring 82 is identical with the direction that a side of recess 46 (Fig. 2) is pushed to by spring 54, is exactly right in Fig. 3.And, in Fig. 3, the 85th, block comes off so that wire rod 5 is unlikely above pin 80, and the 86th, be fixed in the flange of pin pressure pin 84, the 88th, support unit is supported the pin pressure pin 84 that passes movably in through hole.Support unit 88 and chuck 20, nozzle holder 30, cylindrical shell 72 grades of tension disk 70 are fixed on the not shown common base together.

Below the automatic coil winding machine that so constitutes of explanation be operated in Fig. 1 and state shown in Figure 3 is, make directional nozzle 32 with 12 rotations of nozzle holder 30 solderless wrapped connection terminals, after being wrapped on the binding post 12, fall moving slider 40 among wire rod 5 enters recess 46 to wire rod 5.The wire rod 5 that twines at binding post 12 becomes the lead-in wire of the winding origination side of coil, and directional nozzle 32 is in the inside of the outer nozzle 60 that descends with moving slider 40., the end of wire rod 5 is by tension disk 70 clampings, and as shown in Figure 3, by the power of spring 82, pin 80 compresses wire rod 5.Thereby the wire rod 5 between binding post 12 and the tension disk 70 is in unflagging tensioned state.

After the coiling of the binding post 12 of coiling initial side conductor wire finished, unwanted wire rod, promptly the wire rod 5 that extends to tension disk 70 from binding post 12 cut off removals by following mode.Under the state of Fig. 3, make moving slider 40 thresh back and forth movement by left and right directions among the figure with nozzle holder 30, shake wire rod 5 with recess 46.The position of wire rod 5 when the double dot dash line among the figure has been represented to shake.Thus, the angular position by the big binding post 12 of curvature makes wire rod 5 produce metal fatigue, to ten shaking for several times, the part of reeling to binding post 12 is cut off by for several times.At this moment, when moving slider 40 is done the large amplitude back and forth movement from initial position, owing on binding post 12 and bobbin 10, having applied excessive power, Yi Bian increasing mobile range inchmeal, do on one side after the several back and forth movement, back and forth movement gets final product for several times under certain amplitude.And fall owing to the little outer nozzle 60 of front end curvature this moment, so can not cut off wire rod 5 at the front end of directional nozzle 32.

Utilize the back and forth movement of moving slider 40, on wire rod 5, produce the effect of metal fatigue, must make wire rod 5 remain on unflagging tensioned state.Utilize spring 82 to force in pin 80, it is pressed to the right of Fig. 3, thereby realize tightening of wire rod 5.Along with shaking of moving slider 40, wire rod 5 produces and stretches, and this stretched portion is also absorbed by spring 82, thereby makes wire rod 5 keep tensioned state.When keeping often tightening with wire rod 5, wire rod 5 applied excessive power in order to prevent moving slider 40 direction to move left, the spring 82 of giving pin 80 potential energy plays cushioning effect.On the other hand, when Fig. 3 right moved, for preventing sharply to apply brute force to wire rod 5, the spring 54 of giving flap 50 potential energy played the effect of buffer unit at moving slider 40.

As mentioned above, after the root of binding post 12 cuts off wire rod 5, unclamp the end that tension disk 70 is removed unnecessary wire rod 5, promote moving slider 40 simultaneously, make the front end of directional nozzle 32 outstanding from the lower ends downward of outer nozzle 60.Then, after directional nozzle 32 moves on to precalculated position on the bobbin 10, rotary chuck 20, wound skein product 5 on bobbin 10, form coil.After bobbin 10 coilings finished, directional nozzle 32 was around another binding post 12 rotations, and the lead-in wire that making thus reels stops side is on binding post 12.

Subsequently, as shown in Figure 4, make nozzle holder 30 roughly behind the circle, close tension disk 70 and clamp wire rod 5 in rotation around the tension disk that unclamps 70.In the rotation, wire rod 5 is pressed to pin 80 around directional nozzle 32 tension disks 70, makes spring 82 (Fig. 3) compression, thereby the wire rod 5 between binding post 12 and the tension disk 70 is fully tightened.

Then, as shown in Figure 5, nozzle holder 30 is the position among wire rod 5 passes through recess 46 near bobbin 10 and decline moving slider 40.Then, with above-mentioned situation in the same manner, make recess 46 back and forth movements of moving slider 40, by shaking wire rod 5, cutting off in the part of reeling to binding post 12.Afterwards, when secondary coil winds the line, at first, promote moving slider 40, moving nozzle support 30 simultaneously, make wire rod 5 between tension disk 70 and the directional nozzle 32 shift to pin 80 in face of.Then, make from outer nozzle 60 outstanding directional nozzles 32 and rotate around predetermined binding post 12, after the wound wire 5, fall moving slider 40 with nozzle holder 30.So, owing to return to the state of Fig. 1, thereby can repeat above operation.

After having finished whole coilings, take off bobbin 10, change new bobbin 10, repeat a series of operation from chuck 20.Face and, when adopting tractive cutting-off method cutting diameter to be the following thin wire of 0.12mm, needn't shake moving slider 40.At this moment, as shown in Figure 6, the mode that makes moving slider 40 touch wire rod 5 according to its front end position advances along the direction of arrow, can finish cut-out by a tractive cut-out thus shown in double dot dash line.

In addition,, but also can constitute as follows by a side 47 of the recess 46 in swivel plate 50 pie graphs 2, with at the interior side direction of recess 46 by spring energized parts as a side 47, do straight line and move.

According to the present invention,, also can easily cut off, and it is damaged that binding post distortion or bobbin are taken place in the part of reeling to binding post even wire rod is thicker.

And, can compress with bringing in before the swing part for fine rule, cut off by existing tractive cutting-off method, so realized being used for the automatic coil winding machine of the various wire rods from the fine rule to the thick line.
