is formed and fixed in the recess 46. A proximity sensor 47 is provided on the other side of the support shaft 11 and the second movable portion 31, as shown in FIGS. 2, 7, and 8. The proximity sensor 47 is
It is of a type that utilizes optical fiber, and main body tip parts 48 to 50 provided with a light emitting end and a light receiving end are fixed to the support shaft 11 via a fixture 51. The main body tip portion 48 is for detecting the origin of movement of the second movable portion 31, and the main body tip portion 49 is for detecting the origin of movement of the second movable portion 31.
is for detecting the limit point of the left position of the movement, and the main body tip 50 is for detecting the limit point of the right position of the movement. A reflector 54 is attached to the second movable portion 31 via a fixture 52 and an arm 53. The proximity sensor 47 is not limited to the optical fiber type, and various types can be used. Moreover, the first and second guide nozzles 2
The centers of the holes 2 and 45 are arranged in a straight line when winding the coil core and when attaching the coil core to the connection terminal. In FIG. 1, reference numeral 70 denotes a support that supports the second movable portion 31 on the support shaft 11 in a movable manner.

For example, when a red wire is inserted into the first guide nozzle 22 and a blue wire is inserted into the second guide nozzle 45, and when they are attached to the connection terminal of the coil core, the colors of the wires are swapped left and right. Assume that it becomes necessary to switch the positions of the nozzles 22 and 45 from side to side, such as by attaching them to the connection terminals. At this time, from the state where each nozzle 22, 45 is positioned as shown in FIG.
To replace the cylinders 2 and 45, first stop the supply of air to the air cylinder 17 and open the inside. Accordingly, as shown in FIG. 10, the spring 2
The first movable portion 16 retreats with respect to the support shaft 11 due to the elastic biasing force of 0. As a result, the first guide nozzle 22 retreats to a position where it cannot collide with the second guide nozzle 45. Next, the stepping motor 36
The worm 42a and the worm gear 42 are driven.
The pinion 44 is rotated via b. Since the rack 34 is engaged with the pinion 44, the second movable portion 31 moves in the direction indicated by arrow A in FIG. Next, the first guide nozzle 22
When the distance between the guide nozzle 45 and the second guide nozzle 45 reaches a position corresponding to the distance between the connecting terminals of the coil core to which the wire is to be attached, the stepping motor 36 is stopped, and the air cylinder 1 is stopped.
7 to advance the first movable part 16 against the elastic bias of the spring 20, thereby moving the first guide nozzle 22 forward as shown in FIG.
and the second guide nozzle 45 are interchanged left and right. When changing the positional relationship shown in FIG. 12 to the positional relationship shown in FIG. 9, the same procedure as above may be used, except that the stepping motor 36 is reversed. Furthermore, the distance between the first guide nozzle 22 and the second guide nozzle 45 shown in FIGS. 10 and 12
In order to adjust only t ₁ and t ₂ to match the distance between the connection terminals of the coil core, the stepping motor 36 is rotated forward or reverse, and the second movable part 31 is rotated in the longitudinal direction of the support shaft 11. You can adjust the spacing as desired. The amount of movement of the second movable part 31 is controlled by detecting the distance from the origin between the main body tip 48 and the reflector 54.
When the movement limit point 50 is reached, the movement stops so that no further movement is possible. Wires are attached to each connection terminal by operating the column 12, that is, the support 11, by a power source (not shown), just as in the conventional case. This operation moves the first and second guide nozzles 22, 45 circularly around each connection terminal, and at the same time moves them in the axial direction of the connection terminal by the diameter of the wire, so that the wires do not overlap. The wire is wound at a predetermined pitch equal to, for example, the diameter of the wire.

When attaching to this connection terminal, the center of the winding motion of the coil core 56 P ₁ as shown in FIG.
In order to attach the wires 57 to the connecting terminals 55 provided perpendicularly to the wires, the guide nozzles 22 and 45 simultaneously attach the wires 57 to the connecting terminals 55 in the same posture as the bifilar winding around the coil core 56. Furthermore, as shown in FIG. 14, when attaching the starting and ending ends of the wire 60 to the connecting terminal 59 provided parallel to the center P ₂ of the winding motion of the coil core 58, an air cylinder (not shown) is driven to loosen the wire 60. 15 and rotates the pinion 14 that meshes with the rack 15. Since the support shaft 11 is fixed to the pinion 14, the support shaft 11 and the first and second movable parts 16, 31 are rotated. rotates 90 degrees. This rotation rotates 90 degrees around the tips of the first and second guide nozzles 22 and 45.

Then, the support shaft 11 is operated by a power source (not shown) in the same manner as described above, and each guide nozzle 22, 45 is moved in a circular motion around the connection terminal 59, and simultaneously moved in the axial direction of the connection terminal 59. The wire 60 is wound at a predetermined pitch. At this time, the wire 60 is received by the roller 29 and is guided to be unwound.

"Effects of the Invention" As described above, according to the wire guide device for an automatic winding machine according to the present invention, when performing bifilar winding using two wires on the coil core,
It is possible to connect the starting end or the terminal end of the wire to each connecting terminal of the coil core at the same time, and even if the distance between each connecting terminal changes depending on the type of coil core, the first and second movable The distance between the guide nozzles that guide each wire can be freely adjusted to match the distance between the connection terminals by simply operating the section, and when making adjustments, the guide nozzles must be moved manually using tools, etc. It is extremely convenient to use without the need for such complicated procedures.
