れ、滴下ノズル１５から含浸ワニス１６が滴下される。FIG. 3 is an explanatory diagram showing in detail the operation in the above four stations. As shown in the figure, a taper is formed on the entrance side between the first station 11 and the second station 12 and between the second station 12 and the third station 13 only for the positioning pin 9. Guide rails 21 are respectively arranged, and in the second station 12 and the third station 13, there are π-shaped positioning means 22 for sandwiching the positioning pin 9 between two legs, one from above and the other from above. It is arranged to be vertically movable from below. The white arrow in the figure indicates the traveling direction of the conveyor. As shown in FIG. 2, the stator 1 and the rotor 2 mounted on the conveyor 5 reach the first station 11 after being preheated in the preheating chamber A. The positioning pin 9 protruding from the positioning plate 8 is in a rotatable state as shown in FIG. In this state, when the conveyor 5 advances in the direction of the arrow, the positioning pin 9 moves to the guide rail 21.
The pin 9 enters a narrow guide path along the taper and the turning position of the pin 9 is restricted to a horizontal neutral position in the advancing direction or the retreating direction. Eventually, when the positioning pin 9 exits the gap of the guide rail 21 and reaches the second station 12 or the first dropping position, the first positioning means 22a descends with the π-shaped foot facing downward. Then, the positioning pin 9 is pressed downward, so that the positioning pin 9 comes to the lower side. After that, the positioning pin 9 is sandwiched between the π-shaped legs of the positioning means 22a, and the positioning plate 8 is stopped in the state shown in the figure. FIG. 4 is an explanatory view showing an example of the postures of the stator 1 and the rotor 2 corresponding to this state. The desired surfaces 1a and 2a of the coils are fixed upward for a predetermined time, and the impregnating varnish 16 is dropped from the dropping nozzle 15. To be done.

１６が滴下される。Similarly, the second station 12 to the third station 1
Even when moving to 3, the positioning pin 9 does not move to the guide rail 2
When it is brought to the neutral state by 1 and reaches the third station 13, that is, the second dropping position, the second positioning means 2
2b is a π-shaped leg, and now it's going up
The positioning pin 9 is pushed upward to rotate the positioning plate 8 180 degrees opposite to the position of the first station, and the stator 1 and the rotor 2 are moved to the desired surface 1 of the coil shown in FIG.
The impregnating varnish 16 is dripped from the dropping nozzle 15 while the surfaces 1b and 2b on the opposite side of a and 2a are fixed upward for a predetermined time.

加熱されて、硬化が進行する。After the impregnating varnish of the coil has been dropped from both sides in this way, the conveyor moves to the fourth station 14, that is, to the drying position, and as described above, the rotating sprocket 7 is driven by the drive roller 17 to drive the stator 1. The rotor 2 is heated while rotating so that the impregnated varnish does not drop, and the hardening proceeds.
