However, in the prior art shown in FIG.
need to be formed to match the slot of the core 51, which complicates the device and cannot be used with cores of different sizes.

Further, when inserting the coil 53 into the slit of the blade 54, manual work by the operator is essential, so it cannot be automated.
It is necessary to finish the blade, and dimensional accuracy of the blade is required. - On the other hand, in the prior art shown in FIG. 7, the nozzle 55 rotates through the narrow opening of the slot 52, so it is restricted by the opening, and the area ratio of the electric wire, so-called space factor, is reduced, and the electrical characteristics are improved.

Furthermore, in any of the conventional techniques, the wires intersect with each other and the coil is disturbed, resulting in deterioration of characteristics and cannot be applied to detection stators, etc., which require high electrical characteristics. , has some problems.

The present invention has been made in consideration of the problems of the prior art, and an object of the present invention is to provide a winding device that can reliably form a coil with a simple structure.

[Means for solving problems]

In order to achieve the above object, the present invention is such that a coil is formed in advance by winding an electric wire around a winding core, and the coil is inserted directly from the winding core into a slot of an iron core. Therefore, the winding device according to the present invention includes a winding core around which an electric wire is wound to form a coil, and a winder arm that winds the electric wire around the winding core while rotating around the winding core layer. winder means that moves forward and backward with respect to the core; positioning means that supports the winding core so as to move the coil to a position where it can be inserted into the slot of the iron core; and a slider that slides in the axial direction of the winding core to push out the coil. and a slider means for sliding the slider.

FIG. 4 is a perspective view showing the operation, and FIG. 5 is a plan view showing the same operation. Support stands 17 and 18 are disposed at the upper and lower parts of the left and right columns 21° 218, and the slide means 1 is attached to the upper support stand 17, and the winding core 13 is supported on the lower support stand 18. A 5 yen lowering device 20 is attached. Further, a rotation support device 8 for supporting an iron core 4 such as a stator is attached to the intermediate portion of the support column 21.218. The core 4 is supported by the rotary support device 8 by being placed on a rotary plate 7 extracted from the rotary support device 8, and the outer peripheral surface of the core 4 is chucked by the rotary plate 7. Such a rotation support device 8, which may be configured to rotate the core 4 intermittently by a constant angle, positions the winding core 13 and the slot 5 of the core 4 in the horizontal direction, which will be described later. The lifting device 20 consists of a cylinder 19 and a rod 19a of the cylinder 19, and a winding core 13 is attached to the upper end of the rod 19a. Therefore, when the cylinder 19 is driven, the winding core 13 moves up and down, and the winding core 13 is inserted into the iron core 4 at the upper end. As a result, the winding core 13 is positioned relative to the iron core 4 in the vertical direction. Therefore, in this embodiment, the rotation support device 8 and the R1 device 20
A positioning means for positioning the winding core 13 relative to the winding core 13 is configured.

As shown in FIGS. 2 and 3, the winding core 13 is formed in a predetermined outer shape to form a coil, and is attached to the rod 19a of the lifting device 20 so as to form an ITJ shape. winder means 22. on both sides thereof.
22a is provided. Further, a pair of left and right sliders 9°9a are extrapolated to the winding core 13, and the sliders 9, 9a
By sliding the coil in the axial direction of the winding core 13, the coil is pushed out, which will be described later. In this case, each slider 9.
An inclined surface 23.23a is formed on the corresponding surface of 9a, and the above-mentioned sliding is performed by driving a sliding means 1, which will be described later. Reference numeral 10 denotes a return spring that is hooked onto the projections 11 and 118 of each slider 9 and 9a.

The winder means 22.228 are disposed in a symmetrical position with respect to the winding core 13, and have a pedestal 16.16a and a pedestal 16.16 that advance and retreat in a linear direction with respect to the winding core 13, respectively.
a rotating device 15.158 mounted on the rotating device 15.15a and a winder arm 14.158 mounted on the rotating device 15.15a.
It consists of 148. Each winder arm 14, 14
In a, an electric wire 12.12a is unwound from a bobbin (not shown), and as the winder arms 14, 14a rotate around the winding core 13, the pedestal 16.16a retreats, so that the wire 12.12a is wound on the outer peripheral surface of both ends of the winding core 13. The wires 12.12a are wound in alignment to form a coil 24.degree. 248. The sliding means 1 consists of a cylinder 2 mounted on an upper support 17 and a wedge 3 mounted on a rod 2a of the cylinder 2. The wedge 3 has an inclined surface 23°238 formed on the slider 9, 9a.
It is formed into an isosceles triangle having the same slope as , and its position is located in the middle of the inclined surface 2j3.23a. Therefore, when the cylinder 2 is driven, the wedge 3 is lowered and the inclined surface 23,
238 and comes into contact with the inclined surface 23.23a. As a result, a surrounding force acts on the sliders 9, 9a, and the sliders 9.9a slide outward in the axial direction of the winding core 13. Due to this sliding, the coils 24.24a are pushed out from the winding core 13 while maintaining their alignment. In addition, the tip surface of each slider 9, 9a has a second
As shown in the figure, a rib 25 is formed, and the coil 24.degree. 24a formed on the winding core 13 is pressed by the rib 25 and is housed in the slot 5 of the iron core 4.

Next, the operation will be explained. First, in the state shown in FIGS. 1 and 2, the winder means 22.22a is driven to form coils 24.degree. 24a on the outer peripheral surface of both ends of the winding core 13. In this case, the iron core 4 is supported above the winding core 13 by the rotary plate 7 of the rotary support device 8 . After the coil 24° 24a is formed on the winding core 13, the lifting device 20 is driven to move the winding core 13 upward so that it is flush with the iron core 4, and stops at that position. In this state, as shown in FIG. 3, coils 24, 248 are formed on the outer peripheral surface of the winding core 13.

In this state, the rotation support device 8 rotates to rotate the iron core 4 so that the coils 24, 24a of the winding core 13 are aligned with the openings of the slots 5 of the iron core 4. Next, the sliding means 1 is driven and the wedge 3 is lowered. As a result, the wedge 3 is inserted between the sliders 9.9a and comes into contact with each inclined surface 23.238, as shown in FIG.
slides axially outward of the winding core 13 against the return spring 10. Figure 5 shows such a situation,
The coils 24,248 formed on the winding core 13 are pushed into the corresponding slots 5 and removed from the winding core 13. After the coil 24.degree. 248 is inserted, the wedge 3 rises and the sliders 9, 9a are returned to their original positions by the return spring 10. Then, the winding core 13 is lowered to the winder hand &22.228 by driving the lifting device 20, and the next winding is performed. Therefore, the coil can be automatically applied to the slot 5 of the iron core 4, and since only the coil is inserted through the opening of the slot 5, the space factor can be increased.

Note that various modifications can be made to the present invention.

The winder means may be disposed only on one side of the winding core, or a slider may be attached to the cylinder and the slider may be slid by the cylinder. In this case, the wedge 3 is not required, making processing easier. Alternatively, the elevating device that supports the winding core may be made rotatable with respect to the iron core to serve as a positioning means.

〔Effect of the invention〕

As described above, according to the present invention, the electric wires are wound in alignment around the winding core to form a coil, and only this coil is pushed into the slot of the iron core, so that the winding around the iron core can be performed automatically. , the space factor also improves. In addition, the coil can be formed accurately and can be applied as is to iron cores of different sizes, increasing versatility.
