By engaging 74, the center position of the jig 10 with respect to the chuck 13 is uniquely determined.

Instead of the work holding part 12 shown in FIG. 6, a work holding part 75 eccentric from the axis is formed at the tip of the jig 10 'as shown in FIG. The central axis W of the workpiece W in the direction orthogonal to the tool axis
It is also possible to employ a jig provided with an insertion hole 75a for inserting a. In this case, the jig 10 'in which the central axis Wa of the work W is inserted into the insertion hole 75a of the work holding portion 75
By the chuck 13 of the turntable 16
Connected to the spindle 3. The work W is located substantially in the center of the jig 10 ', and while the work W is continuously rotated in one direction by the continuous rotation of the spindle 3, the wire Wi supplied from the nozzle N is attached to an arbitrary pole of the work W, a so-called spindle. It is wound by winding. The rotation phase of the work W relative to the jig 10 'is that the stopper 75b having a convex curved surface is the spring 75
It is pressed and fixed between the polar gaps of the work W by c.
When the winding of a certain pole is completed, the feed member 75d for indexing and rotating the work W pushes and moves the work W so as to rotate the work W by a predetermined angle in the pole gap, and the spindle can be wound around another pole. At this time, the stopper 75b is the spring 7
The workpiece W is retracted against the biasing force of 5c, and the index rotation of the work W is allowed.

As described above, the work W is attached to the jig 10 shown in FIG. 6 and the flyer winding is performed on the work W, or the jig 1 shown in FIG.
The work W can be attached to 0'and the work can be spindle-wound. Which of these winding methods is selected can be determined by appropriately selecting a work holding jig according to the purpose of the work.

First, in FIG. 1, the jig 10 is held on each chuck 13 of the turntable 16. The jig 10 to be used has a common connecting portion 11 and chuck holding portion 14, and the work holding portion 12 is used properly according to the type of the work W. When the jig 10 is mounted on the spindle 3 of the winding portion 2 as shown in FIG. 1 and winding is performed, the chuck release cylinders 40 and 41 shown in FIG. 3 extend to each other and keep the chuck 13 open. Then, the chuck 13 is prevented from interfering with the indexing rotation of the jig 10. The fryer 1 shown in FIG. 1 has a flyer winding for each pole of the work W,
The jig 10 is sequentially indexed and rotated through the motor 6, the timing belt 8 and the spindle 3 to complete the fryer winding.

After that, as shown in FIG. 3, the chuck release cylinders 40 and 41 are retracted, and the chuck 13 is moved to the winding portion 2.
The jig 10 is held. In this state, the lifting cylinder 25 contracts as shown in FIG.
Raise 6 As a result, the connecting portion 11 of the jig 10 is separated from the spindle 3. In this state, the rotary actuator 22 operates and the turntable 16 rotates 180 degrees. As a result, the work W after winding, which is held by the jig 10 in the winding part 2, moves to the idle part 15 on the opposite side, and conversely, the work W before winding, which is held by the jig 10 in the idle part 15 is reversed. W turns 180 degrees and reaches the winding part 2. Then the turntable 16 is lifted by the lifting cylinder 25.
Is lowered and the jig 10 of the winding part 2 is connected to the spindle 3. After that, the chuck 13 is opened, and the fryer 1 winds a new work W as described above.

In the idle portion 15 on the opposite side of the winding, for example, an operator removes the work W after winding from the jig 10 and mounts a new work W before winding on the jig 10. You can wait. Then turntable 16
The work W that has been wound and the work W that has not yet been wound are exchanged with the rotation of 180 degrees. When a conveyor is provided adjacent to the idle section 15, a load / unload device (for example, a robot) that transfers the work holding jig 10 between the idle section 15 and the conveyor is provided to allow the idle conveyor to operate. In the section 12, the work after winding and the work not yet winding can be delivered together with the jig 10. In this case, the chuck opening cylinder 40 and the like are also installed in the idle section 12.

Next, another embodiment of the present invention will be described with reference to FIG. In this embodiment, the turntable 78
On the other hand, the four chucks 13 are evenly arranged at the center O thereof.
Is provided, and the jig 10 is held on each chuck 13.
It is a shaft type. The turntable 78 has a rectangular shape, and the two chucks 13 provided on one long side of the turntable 78 correspond to the winding portions 2, respectively. In other words, it corresponds to each flyer 1. The two chucks 13 located on the opposite long sides correspond to the idle portions 15, respectively. That is, in this example, two of the chucks 13 are simultaneously positioned in the winding portion 2, and the chucks 13 on the opposite side are simultaneously positioned in the idle portion 15, respectively. Then, a spindle 3 such as an index is fixedly mounted on each winding portion 2 so as to correspond to each fryer 1 on a one-to-one basis. In addition, chuck opening cylinders 40 and 41 are fixedly provided on both sides of the winding portion 2 sandwiching the winding portion 2.

As shown in FIG. 26, the two chucks on one side are supported by two support shafts 80 and 81 slidably mounted on the revolving frame 79. Each support shaft 80, 81
Penetrates the clamp pieces 30, 31 of each chuck 13. The clamp piece 30 of each chuck 13 is fixed to the support shaft 80, but is slidable with respect to the support shaft 81. While the other clamp piece 31 is fixed to the support shaft 81, it can slide on the support shaft 80. The compression spring 35 similar to that described above is inserted between the swivel frame 79 and the clamp pieces 30 and 31 on both sides in a pre-compressed state. 37 and 38 are provided in the form of flanges on the respective support shafts 80 and 81, and are provided in the middle of the revolving frame 79.

As shown in FIG. 19, each rotation guide shaft 84
Is adapted to be relatively non-rotatably fitted from above into a work holding portion 12 (a portion which penetrates the work W and projects upward) located on the upper end side of the jig 10.
4 is rotatably attached to the elevating frame 85. Therefore, when the rotation guide shaft 84 is coaxially coupled to the jig 10 from above, the rotation guide shaft 84 also rotates integrally with the jig 10 as the jig 10 is index-rotated by the spindle 3. Jig 1
Prevents misalignment due to 0 rotation. It should be noted that a diametrical engagement groove 64a is formed at the upper end of the jig 10 as shown in FIG. 6, and a not-shown engagement fitting into the engagement groove 64a at the lower end of the rotation guide shaft 84 of FIG. Mating protrusions are formed, and by combining these engaging grooves 64a with the engaging protrusions,
The rotation guide shaft 84 and the jig 10 are provided with coaxiality, and relative rotation is prevented.

Further, as shown in FIG. 18, a winding guide 87 is provided corresponding to the work W of each jig 10 in the winding portion 2. Each winding guide 87 advances from the retracted position only when the work W is wound by the flyer 1 to reach the vicinity of the work W, and when the flyer 1 winds one pole of the work W, the wire rod Prevent the wire from interfering with the adjacent pole and guide the wire into the pole so that it can be easily dropped. When the winding is completed, each winding guide 87
Moves back to the retracted position (direction perpendicular to the plane of FIG. 18).
As a result, the jig 10 of the revolving frame 79 and the winding guide 87 do not interfere with each other.

Next, the operation of the winding machine including the above-described work changing device having a four-axis structure will be described. First, in the configuration shown in FIG. 17, in a state where the winding is performed by each flyer 1 in the winding portion 2, the turntable 78 is in a lowered state as shown in FIGS. 20 and 22, and FIG.
As shown in (2), both of the two chucks 13 on the winding portion 2 side are opened. Further, as shown in FIG. 24, when the rotation guide shaft 84 is lowered, the rotation guide shaft 84 is fitted into the tip portion of each jig 10 to guide the index rotation of the jig 10. A winding process is simultaneously performed on two workpieces by each fryer 1 in FIG. 17, and the jig 10 is used in the winding process.
As a result, the work W is index-rotated.

When the winding of the two works W is completed, as shown in FIG. 25, the rotation guide shaft 84 is lifted by the operation of the lifting cylinder 86 and separated from each jig 10. Further, as shown in FIG. 26, the two chucks 13 on the winding portion 2 side are synchronously closed, and the jig 10 holding the workpiece W whose winding is completed is clamped. Further, as shown in FIGS. 21 and 23, the lifting cylinder 25 operates,
The turntable 78 moves up together with the chuck 13 and the jig 10. As a result, the jig 10 of the winding part 2 is separated from the spindle 3. After that, the rotary actuator 22 of FIGS. 21 and 23 is operated, the turntable 78 is rotated 180 degrees, and in FIG. 17, the jig 10 for holding the work after winding is swung to the idle portion 15 and moved. In the idle part 15, the jig 10 holding the unwound work is replaced with the jig 10 and positioned in the winding part 2.

28 and 29 show the above steps with time. The winding operation is performed as shown in FIG. 28 (a), and the winding mechanism (flyer 1) as shown in FIG. 28 (b).
Moves backward, and the rotation guide shaft 84 rises as shown in (c). Further, as shown in FIG. 29 (a), the turntable 78 is raised, and the work after winding is exchanged with the work before winding by the rotation of 180 degrees, and as shown in FIG. The table 78 is lowered (the jig 10 and the spindle 3 are connected), and further, the rotation guide shaft 84 is lowered (the fryer 1 is advanced), the chuck 13 is opened, and the winding is started, as shown in FIG. .

As described above, in order to simultaneously wind two or more workpieces in the winding portion 2 and replace two or more unwound workpieces with the winding portion 2, as shown in FIG. As shown in the drawings, it is also possible to provide two biaxial work exchanging devices having the turntable 16 shown in FIGS. However, in that case, the lateral dimension L2 becomes large. In other words, the pitch Pb of the flyer
Will grow to some extent. On the other hand, as shown in FIG. 30A, in the case of a four-axis work exchanging device having a turntable 78, the lateral dimension L1 can be made considerably smaller than L2, and the pitch between the fryer (in other words, the winding portion). Pitch Pa) can be reduced, and more winding parts can be set in a limited space.

Further, it is also possible to connect the four-axis work changing device shown in FIG. 30 (a) laterally (FIG. 3).
1). At that time, the maximum rotation loci S of the four-axis turntable 78 can be laterally connected with a predetermined gap between the loci S so as not to interfere with each other. That is, when the turntables 78 are simultaneously rotated, if the maximum rotation loci S overlap each other, they may interfere with each other to make it difficult to rotate.
First, it is conceivable to arrange them so that they do not overlap. However, with such an arrangement, the chuck 13
In some cases, it is difficult to set the interval between them, in other words, the pitch L3 of the winding portion, to be the same in each of the turntables extending in the horizontal direction. For example, if the chuck spacing L3 between one turntable 78 and the chuck spacing between adjacent turntables 78 are different, it may not be possible to deal with the case where the winding portions, and thus the flyers, are arranged at equal intervals.

Therefore, the maximum rotation loci S of the respective turntables 78 are arranged so as to be the same so that the chuck intervals L3 are all equal among the plurality of turntables 78. In the case of overlapping in this way, if the turntables 78 are rotated in synchronization, there is a risk of collision of members between the adjacent turntables 78. It is possible to shift the rotation timings from each other or to reverse the rotation direction. For example, the first, second, and third turntables 78 start rotating one after another,
Further, the respective turning mechanisms are controlled in association with each other so as to end the rotation of 180 degrees. Alternatively, the rotation directions of the adjacent turntables 78 are controlled so as to be opposite to each other. As a result, even if the maximum rotation loci S of the turntables 78 overlap, it is possible to avoid the collision of members and to make the pitches between the chucks continuous in the lateral direction the same. Note that this is substantially the same even when the maximum rotation trajectories S of the two-axis, two-turn turntables 16 overlap each other, as shown in FIG.

Like the turntable 88 shown in FIG. 32, for example, a six-axis chuck 13 is provided, and this chuck 13
It can also be rotated 80 degrees. In this case, since the maximum rotation locus S'is somewhat larger than that of the case of four axes, it is necessary to secure a space in consideration of it. Further, as shown in FIG. 32, for example, a 6-axis turntable 8
It is also possible to connect 8 in the horizontal direction.
