In the actual manufacturing process, a plurality of pallets 64 are placed on the conveyor 62 as shown in FIG. 4 around the armature attaching / detaching / reproducing apparatus 120 as an example. The process is performed continuously. Thus, a large number of motors 10 are manufactured continuously.

(Motor Disassembly Step) For example, the used motor 10 is disassembled and separated for each part for disposal or recycling. In disassembling the motor 10, the motor manufacturing and disassembling apparatus 60 is operated as follows. At this time, the conveyor 62 sequentially moves the pallets 64 in the direction of arrow B in FIG.

Thus, the disassembly of one motor 10 and the separation of the components are completed. As in the case of manufacturing the motor 10, the plurality of motors 10 are sequentially disassembled by sequentially transporting the plurality of pallets 64.

On the other hand, when a predetermined amount of the motor 10 is disassembled as described above and a predetermined amount of the armature 124 is placed on the tray 124 of the armature attaching / detaching / reproducing apparatus 120, the tray 124 is transferred to the reproducing apparatus 130 by the transport conveyor 126. Transport to The playback device 130 checks whether the transported armature 26 is reusable and checks whether the reusable armature 2 is reusable.
Play 6. That is, the commutator 28 that has been soiled by contact with the brush is ground or cut, the washer 32 that has deteriorated by contact with the bearing metal 18 is replaced by a washer attaching / detaching device, and finally, the dirt and dust attached to the armature 26 are cleaned. Eliminate (wash) with the device. Also, the playback device 13
0 transfers the reproduced armature 26 to the stocker 132, and the stocker 132 transfers the transferred armature 2 to the stocker 132.
Store 6.

The motor manufacturing and disassembling apparatus 60 performs the step of regenerating the armature 26 and the step of disassembling the motor 10 in parallel. Thus, in the motor manufacturing / disassembling apparatus 60, for example, the motor 10 can be manufactured in the daytime, and the motor 10 can be disassembled and the armature 26 can be regenerated and stored at night.

The stored armature 26 is used as the armature 26 for manufacturing when the motor manufacturing and disassembling apparatus 60 performs the above manufacturing process (for example, during the daytime).
2 and used to manufacture a new motor 10.

As described above, in the motor manufacturing / disassembling apparatus 60, the yoke supply / discharge device 70, the frame end supply / discharge device 80, the bearing metal attaching / detaching device 90, the magnet attaching / detaching device 100, the brush attaching / detaching device 110, the armature attaching / detaching / reproducing device 120, the frame The bearing metal 18, 38, magnets 22A, 22B (spring 24), power supply terminal 52 (brush 50), armature 26 (washer 32), and frame end The motor 10 assembled in this order is disassembled by removing the above components in an order reverse to this order.

That is, when disassembling the motor 10, the motor 10 is caused to flow on the motor manufacturing and disassembling apparatus 60 (conveyor 62) in the direction opposite to the direction of manufacture (the direction of arrow B in FIG. 3), and the frame end 34, the armature 2
6, power supply terminal 52 (brush 50), magnet 22A,
22B, the bearing metal 18 is removed from the yoke 12 in this order, and finally the frame end 34 and the yoke 12 are discharged from the assembly line to complete the disassembly.

As a result, the motor manufacturing and disassembling apparatus 60
The motor 1 is installed in the reverse order to the assembly order at the time of manufacturing the motor 10.
Since the components that make up the motor 0 are removed and disassembled, they can be used as they are when disassembling the motor 10, and there is no need to separately provide a dedicated device (disassembly line) for disassembly of the motor 10 as in the related art. Further, the disassembling step (work) by the motor manufacturing and disassembling apparatus 60 is efficient because it does not depend on humans.

In disassembling the above parts, the device used for assembling the parts is used. That is, the yoke supply / discharge device 70 for supplying the yoke 12 is used.
The frame end 34 is discharged by the frame end supply / discharge device 80 for supplying the frame end 34, and the bearing metals 18 and 38 are pressed by the bearing metal attaching / detaching device 90 for press-fitting the bearing metals 18 and 38.
8, magnets 22A, 22B are attached by a magnet attaching / detaching device 100 for assembling the magnets 22A, 22B.
22B is removed, the power supply terminal 52 (brush 50) is removed by the brush attachment / detachment device 110 for attaching the power supply terminal 52 (brush 50), the armature 26 is removed by the armature attachment / detachment / regeneration device 120 for attaching the armature 26, and the frame end 34 is attached to the frame end. Since the frame end 34 is removed by the attachment / detachment device 140, it is necessary to newly provide a dedicated disassembly device (for example, a dedicated device only for removing the bearing metal 18) in each step of the motor manufacturing disassembly device 60 for removing each component of the motor 10. Cost is further reduced.

Further, in order to regenerate and reuse the armature 26 which has been disassembled and removed in the manufacture of a new motor 10, the armature 2 which is discarded with the disassembly of the motor 10 is used.
6, the number of new armatures 26 to be manufactured is reduced, and the cost is reduced. In particular, armature 26
Is a composite of an iron-based material and a copper-based material, and has a structure in which a winding of the copper-based material is wound around a laminated core of the iron-based material. The merits of reuse are great. That is, the cost is further reduced by reusing the armature 26, which is difficult to recycle as a material or simply discard.

As described above, in the method of manufacturing the motor 10 by the motor manufacturing and disassembling apparatus 60, the motor 10 can be disassembled without newly providing a dedicated apparatus for disassembling the motor 10, and the number of parts to be discarded due to the disassembly of the motor 10 is reduced. Reduction is achieved and cost is reduced.

In the above embodiment, the armature 26 is used as a component to be reused for manufacturing a new motor 10. However, the present invention is not limited to this, and all reusable components are reused. Is also good. Therefore, for example, the yoke 1
2, bearing metals 18, 38, magnets 22A, 22
It goes without saying that some or all of B, the spring 24, the power supply terminal 52 (brush 50), and the frame end 34 may be reused together with the armature 26 or in place of the armature 26. Further, when the motor 10 has a configuration including components other than the above, it is needless to say that the components other than the above may be reused. In these cases, in the regenerating step, grinding, cutting, cleaning, partial replacement of component parts, and the like are appropriately performed according to the part to be regenerated.

In the above-described embodiment, the regeneration step of the armature 26 includes grinding or cutting of the commutator 28,
The replacement of the washer 32 and the cleaning of the armature 26 have been described. However, the present invention is not limited to this, and the regeneration step only needs to include the minimum steps required for reuse. Alternatively, other necessary regeneration steps (for example, cutting or polishing) may be performed together with these. Further, only the necessary regeneration process may be selectively performed according to the inspection result of the armature 26. Furthermore, it goes without saying that the regeneration step including this inspection may be performed manually without depending on the reproduction apparatus 130. Furthermore, in the above-described embodiment, the armature 26 placed on the tray 124 by a predetermined amount is transported to the reproducing device 130. However, the present invention is not limited to this. Armature 1
It is needless to say that 26 may be transferred to the reproducing apparatus 130 one by one.

Further, in the above embodiment, the yoke 1
Although the process (apparatus) for assembling each component and the process (apparatus) for assembling each component on the frame end 34 are appropriately mixed, the present invention is not limited to this, and the components are assembled on the frame end 34. The process (apparatus) may be arranged anywhere before the process of assembling the frame end 34 to the yoke 12. Therefore, for example, the bearing metal 38 and the power supply terminal 52 (brush 50) may be assembled to the frame end 34 in a pre-process (upstream process during manufacturing) of the yoke supply / discharge device 70 or in another line. In this case, the disassembling step is also changed so as to be the reverse of the manufacturing step.

Furthermore, in the above-described embodiment, the components constituting the motor manufacturing and disassembling device are connected by the conveyor 62. However, the present invention is not limited to this. Pallet 64 by carrier or moving cart
May be transported, and the robot (Robot 7
6) may directly convey the yoke 12 and the like to the next step.

Further, in the above-described embodiment, a preferable configuration is adopted in which all the steps of manufacturing and disassembling are automated. However, the present invention is not limited to this, and manual operations may be performed in some of the steps.
This configuration is effective when the method for manufacturing a rotating electrical machine according to the present embodiment is applied to a manufacturing line including a manufacturing process using existing manual operations.

Further, the number of devices (for example, the brush attaching / detaching device 110) constituting the motor manufacturing / disassembling device 60 or the number of robots constituting the respective devices is not limited to the above-described embodiment. It can be appropriately determined according to the processing time of the process (apparatus) and the like.

In the above embodiment, the motor 10 is a DC motor having the magnets 22A and 22B and the brush 50. However, the present invention is not limited to this. It may be a motor or a brushless motor. Needless to say, the configuration of the motor 10 which is a DC motor is not limited to the configuration of the above embodiment. Therefore, for example, the yoke 1
2 and the holding structure of the brush holding portion 42 holding the power supply terminal 52 (brush 50) and the magnets 22A and 22B can be appropriately changed. For example, the power supply terminal 52 may be held in an elastically deformed state. A pair of springs 24 is provided on the inner surface of the substantially cylindrical yoke, and a pair of engagement portions are provided to engage with one circumferential end surfaces of the magnets 22A and 22B.
May hold the magnets 22A and 22B. Further, the present invention is not limited to a configuration in which the frame end 34 is fitted into the opening of the yoke 12. For example, a claw provided on the yoke 12 in a state where the end surface of the frame end 34 is engaged with the opening end of the yoke 12. The frame end 34 may be held by the yoke 12 by being caulked.
