BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing a first embodiment of the present invention. (First Embodiment) FIG. 1 is a perspective view showing an entire configuration of a core material winding apparatus for a stator core according to the present invention, FIG. 2 is a view showing a state in which a strip-shaped thin plate is rolled by a rolling roll, and FIG. FIG. 4 is a perspective view of the attached rolling roll, and FIG.

The belt-like thin plate 1 supplied to the core material winding device of the stator core is processed by a belt-like body and fed out by a feeder 30.
It is formed by stamping a steel plate of silicon or the like with a press. The strip-shaped thin plate 1 is provided with an inner notch 2 serving as a slot of a stator core at one end side in the width direction, so that a tooth 3 that partitions the adjacent inner notch 2 and a core that connects the adjacent inner notch 2 are provided. A back 4 is formed. Also,
An outer notch 5 serving as a through bolt passage for fixing the stator core to the stator housing is formed in the core back 4 opposite to the inner notch 2. The outer peripheral notch 5 is a semicircular notch having a shorter depth than the inner peripheral notch 2. The stator manufactured in the present embodiment has 36
The outer peripheral notch 5 is for the stator core 1
Four are formed per circumference. That is, one outer peripheral notch 5 is formed for every nine teeth 3.

The core material winding device for the stator core includes a pair of rolling rolls 10, 11, a rolling roll biasing cylinder 31 for adjusting the pressure of the rolling rolls 10, 11, a side regulating guide 12, a positioning guide 13, a winding guide, and the like. It is composed of a roller 14, a cutter 15, and the like.

The pressure of the rolling rolls 10 and 11 is adjusted by a rolling roll biasing cylinder 31, and applies pressure in a direction approaching each other. These rolling rolls 10, 1
Reference numeral 1 denotes a columnar shape, and its tip end is formed with inclined portions 10b and 11b which are inclined so as to have a small diameter as shown in FIG. Further, the inclined portion 1 of one of the rolling rolls 10
Roller teeth 10a that engage with the inner peripheral notch 2 of the strip-shaped thin plate 1 protrude from the inclined portion 10b at the tip of 0b.

The air cylinder 18 presses the rolling roll 11 against the core back 4 of the strip 1. This allows
The core back 4 is provided with the inclined portions 10 of the rolling rolls 10 and 11.
b, 11b. Each of the cylindrical portions 10c, 11c of the rolling rolls 10, 11 has a flange 10
d and 11d are provided. These flanges 10d,
11d restricts the movement of the rolling rolls 10, 11 in the direction approaching each other. For this reason, as shown in FIG. 2, even when the portion where the outer peripheral notch 5 is provided in the core back 4 passes between the rolling rolls 10 and 11, the flanges 10 and 11 d contact each other. Can be prevented from being rolled too much.

The inclined portions 10b, 1 of the rolling rolls 10, 11
The gap between 1b becomes wider toward the leading ends of the rolling rolls 10 and 11. Therefore, when the rolling rolls 10 and 11 are rotationally driven by the rotary driving device 32, the cores are formed such that the plate thickness decreases toward the edge of the core back 4, that is, the plate thickness decreases toward the edge. The back 4 is rolled. Then, the strip-shaped thin plate 1 is forcibly sent out while being rolled by the rotation of the rolling rolls 10 and 11.

At the end of the inclined portion 10b of the rolling roll 10, a rolling roll tooth 10a is formed to protrude. The rolling roll teeth 10a are provided corresponding to the intervals between the inner peripheral notches 2. Therefore, when the rolling rolls 10 and 11 are rotationally driven by the driving device, the rolling roll teeth 1
0a sequentially engages with all the inner notches 2. The rolling roll teeth 10 a push the side surfaces of the teeth 3 to assist in discharging the strip-shaped thin plate 1 from the rolling rolls 10 and 11.

The band-shaped thin plate 1 rolled by the rolling rolls 10 and 11 is reduced in thickness by deforming the edge on the core back 4 side, so that the core back 4 side is more inward than the inner peripheral notch 2 side. It becomes longer in the length direction of the strip-shaped thin plate 1. as a result,
The belt-like thin plate 1 has a round and curved shape. By continuously thinning the edge on the core back 4 side in this manner, the strip-shaped thin plate 1 is bent substantially in a spiral shape.

The strip-shaped thin plate 1 extruded from the rolling rolls 10 and 11 and bent in a spiral shape is taken up by a take-up roller 14. The take-up roller 14 is held on a pedestal 20, and is driven by a rotary drive device 33 to reduce the rolls 10, 11
It is rotated in synchronization with the rotation of. That is, the rolling roll 10,
The speed at which the belt 11 extrudes the thin strip 1 and the speed at which the winding roller 14 winds the thin strip 1 are set to be equal. The winding roller 14 has a cylindrical shape, and the diameter thereof corresponds to the inner diameter of the manufactured stator core.

A positioning guide 13 is provided on the circumferential surface of the winding roller 14 so as to protrude in the axial direction. The positioning guide 13 is used for positioning the inner peripheral notch 2 in the axial direction when winding the belt-shaped thin plate 1. The alignment guide 13 rotates together with the winding roller 14, and engages with the inner peripheral notch 2 when the winding roller 14 winds the thin strip 1. Also, the alignment guide 14
Pushes the side surface of the teeth 3 to assist the movement of the strip-shaped thin plate 1.

On the outlet side of the strip 1 from the rolling rolls 10 and 11, a side regulating guide 12 is provided. A plurality of the side surface regulating guides 12 are provided on each of the two bar-shaped members 21a and 21b fixed to the pedestal 20, and each has a comb-like shape arranged at predetermined intervals.
The two rod-shaped members 21a and 21b are symmetrically arranged with respect to the center of the winding roller 14, and are arranged such that the comb teeth of the side surface regulating guide 12 face each other. Each of the side regulating guides 12 provided on the rod 21b is opposed to each of the side regulating guides 12 provided on the rod 21a.
Are shifted by a predetermined pitch. These side regulation guides 12 regulate only the side faces of the strip-shaped thin plate 1,
Does not regulate the end. The side regulating guide 12 prevents the thin strip 1 from inclining with respect to the winding rotor 14.

In such a configuration, the winding roller 1
When the belt-like thin plate 1 is wound up by the rotation of 4, the side regulating guide 12 plays the same role as the screw groove, and the belt-like thin plate 1 wound up by the winding roller 14 is pushed out to the tip side of the winding roller 14. , Accumulate in layers.

When the winding roller 14 winds the strip-shaped thin plate 1 by a predetermined amount, the cutter 15 is operated by the driving device 34, and the strip-shaped thin plate 1 is cut by the cutter 15. Then, the strip-shaped thin plate 1 spirally wound by a predetermined amount is transferred to the next step, where it becomes a stator core.

In this embodiment, the flanges 10d, 11d
This restricts the movement of the rolling rollers 10 and 11 in directions approaching each other. Thereby, the gap between the inclined portions 10b, 11b of the rolling rolls 10, 11 is kept constant. As described above, the gap between the inclined portions 10b and 11b to be rolled while the strip-shaped thin plate 1 is sandwiched therebetween is maintained at a fixed size, so that the strip-shaped thin plate 1 is rolled at a position where the outer peripheral notch 5 is present and at a position where it is not. Can suppress the variation in the plate thickness. Then, by suppressing the variation in the rolling, the curvature when the belt-shaped thin plate 1 is formed into a spiral shape can be kept constant.

In the present embodiment, the feeding of the thin strip 1 is performed not only by the rolling rolls 10 and 11 but also by the rolling roll 1.
0 is also performed by the rolling roll teeth 10a. Therefore, the strip-shaped thin plate 1 by the rolling rolls 10 and 11
In the case of sending out, even if a slip occurs between the strip-shaped thin plate 1 and the inclined portions 10b, 11b, the strip-shaped thin plate 1 can be sent out by the rolling roll teeth 10a. It can be done reliably.

In this embodiment, when the number of slots of the stator core to be manufactured is changed, the rolling roll 1
The interval between the rolling roll teeth 10a provided at 0 may be changed in accordance with the slot interval. This change can be made only for the roll 10 or the roll 10 and the roll 11
Can be replaced, and no major modification of the device is required. Therefore, even for the production of stator cores with different numbers of slots,
Can be handled relatively easily.

In the present embodiment, the side regulation guide 1
2 regulates only the side surface of the strip-shaped thin plate 1 and does not regulate the end. Therefore, regardless of the presence or absence of the outer peripheral notch 5 of the band-shaped thin plate 1, the side surface of the band-shaped thin plate 1 can be guided without the outer peripheral notch 5 being caught by the side surface regulating guide 12.

In this embodiment, a positioning guide 14 is provided on the circumferential surface of the take-up roller 14. Then, the positioning guide 14 engages with the inner peripheral notch 2 when the belt-shaped thin plate 1 is wound up. Therefore, the axial position of the inner peripheral notch 2 of the helically wound strip-shaped thin plate 1 can be aligned. In addition, the positioning guide 14 presses the side surface of the teeth 3 to assist the movement of the strip-shaped thin plate 1.

The outer peripheral notches 5 formed on the outer periphery of the strip-shaped thin plates 1 of the respective layers constituting the stator core overlap with each other, and are arranged in a groove shape on the outer periphery of the stator core to form four grooves. Bolts (not shown) are arranged in the four grooves formed by the notches 5 so that the bolts can be attached to a frame (not shown). For this reason, the outer peripheral notch 5 is formed intermittently and periodically on the outer periphery of the strip-shaped thin plate 1. However, the number of the notches 5 may not be four per one circumference of the stator, and may be four or more, for example. In this case, for example, the outer peripheral notch 5 may be formed in synchronization with the inner peripheral unevenness of the strip-shaped thin plate 1. Second Embodiment FIG. 5 is a front view of a core material winding device for a stator core according to a second embodiment. The second embodiment differs from the first embodiment only in the structure of the rolling rolls, and is otherwise the same as the first embodiment.

In the first embodiment, the strip-shaped thin plate 1 is rolled and fed by the rolling roll 10 provided at the tip of the rolling roll teeth 10a. However, the rolling and feeding of the thin strip 1 may be performed as in the second embodiment described below.

The rolling roll 10 'used in the second embodiment,
11 'is not provided with rolling roll teeth. Therefore, the rolling rolls 10 ′ and 11 ′ roll the core back 4 of the strip-shaped thin plate 1 and send it out by friction. On the outlet side of the strip 1 from the rolling rolls 10 ′ and 11 ′, a cylindrical transfer roll 16 for moving the strip 1 is provided. At the tip of the transfer roll 16, transfer teeth 16 a are provided corresponding to the interval of the inner peripheral notch 2. The transfer teeth 16 a are provided on the circumference of the leading end of the transfer roll 16 so as to correspond to the interval of the inner peripheral notch 2. When the transfer roll 16 is rotated by a drive mechanism (not shown), the transfer teeth 16a are sequentially engaged with all the inner notches 2. Then, the transfer teeth 16a push the side surfaces of the teeth 3 to assist in discharging the thin strip 1 from the rolling rolls 10 'and 11'.

Also in the second embodiment, since the belt-like thin plate 1 is transferred by the transfer teeth 16a, the transfer by friction of the rolling rolls 10 'and 11' can be supplemented. Further, since the transfer teeth 16a are provided on the transfer roll 16 separate from the rolling roll 10 ', there is no need to provide transfer teeth on the rolling roll 10', and the structure of the rolling roll 10 'is simplified.

(Third Embodiment) FIG. 6 shows rolling rolls 50 and 51 according to a third embodiment. FIG. 6A shows a case where the outer peripheral notch 5 is located between the rolling rolls 50 and 51.
(B) has shown the case where the outer periphery notch 5 is not located between the rolling rolls 50 and 51. FIG. The rolling rolls 50 and 51
Other than that, the configuration of the core material winding device is the same as that of the first embodiment.

In the first embodiment, the rolling rolls 10
11 are provided with flanges 10d, 11d, but in this embodiment, only the rolling roll 51 is provided with the flange 51a. Further, in the present embodiment, the formation position of the flange 51a is just above the inclined portion 51b, that is, the lowest position of the cylindrical portion 51c.

Thus, the two rolling rolls 50, 51
Even if the flange 51a is provided on only one of the
a can contact the cylindrical part 50a of the rolling roll 50, and can restrict that the rolling rolls 50 and 51 move toward each other. Thereby, the rolling rolls 50, 51
The gap between the inclined portions 50b and 51b is kept constant, and it is possible to suppress the occurrence of variations in the thickness of the strip-shaped thin plate 1 due to the rolling at the portion where the outer peripheral notch 5 is provided and at the portion where it is not. Then, by suppressing the variation in the rolling, the curvature when the belt-shaped thin plate 1 is formed into a spiral shape can be kept constant.

Further, by forming the flange 51a at the above-mentioned position, it is possible to regulate the movement of the strip 1 in the axial direction of the rolling rolls 50 and 51.

(Fourth Embodiment) FIG. 7 shows rolling rolls 60 and 61 according to a fourth embodiment. The configuration of the core material winding device other than the rolling rolls 60 and 61 is the same as in the first embodiment.

In this embodiment, a mechanism for restricting the movement of the rolling roll 61 in the axial direction is provided. As shown in FIG. 7, the cylindrical portion 61 c of the roll 61 has a flange 61.
a is provided. The engagement of the flange 61a with the mechanical stopper 19 restricts the axial movement of the rolling roll 61. When the rolling roll 61 can move downward in the axial direction (downward in the drawing), the inclined portion 61b is lowered downward in the axial direction. The distance to the portion 61b is reduced. However, the roll 6
1 by restricting the axial movement of the rolling roll 6.
It is set so that it does not approach 0 or more than a predetermined distance. Thereby, the inclined portions 60b, 61b of the rolling rolls 60, 61
The gap between them is kept constant. The flange 61a and the mechanical stopper 19 constitute a sizing mechanism for keeping the thickness of the strip-shaped thin plate 1 constant.

As described above, the movement of the rolling roll 61 in the axial direction is restricted by the mechanical stopper 19,
The gap between the 0, 61 inclined portions 60a, 61b can be kept constant. For this reason, the gap between the inclined portions 60b and 61a where the strip-shaped thin plate 1 is sandwiched and rolled is maintained at a fixed size, and the thickness of the strip-shaped thin plate 1 is reduced by the rolling at the portion where the outer peripheral notch 5 is provided and the portion where it is not. Variation can be suppressed. Then, by suppressing the variation in the rolling, the curvature when the belt-shaped thin plate 1 is formed into a spiral shape can be kept constant. (Other Embodiments) In each of the above embodiments, both of the rolls 10 and 11 (50, 51, 60 and 61) were rolled while being inclined with respect to the strip-shaped thin plate 1. However, rolling roll 1
Rolling may be performed while only one of 0 and 11 is inclined. Even in that case, the thickness of the end of the core back 4 of the strip-shaped thin plate 1 may be set to be equal to the thickness of the end of the core back 4 in the first embodiment. That is, one surface of the core back 4 of the strip-shaped thin plate 1 is not inclined, and the other surface may be inclined twice as much as the first embodiment. Even in the rolling as described above, the strip-shaped thin plate 1 is bent substantially helically as in the first embodiment.

In the first and second embodiments, the rolling roll teeth 10a and the transfer teeth 16a are provided so as to correspond to the intervals between the inner notches 2, and are engaged with all the inner notches 2. I made it. However, the rolling roll teeth 10a and the transfer teeth 16a may be engaged with the inner peripheral notch 2 for each of the plurality. Even in that case, it is possible to assist the transfer of the strip-shaped thin plate 1.
