In FIG. 1, the reference numeral 1 designates a vibrating bowl feeder, which is known per se and has a spiral-shaped vibrating bowl 2, and inside the vibrating bowl 2 there is a vibrating bowl 2 which is disposed from the bottom toward the outer periphery. A spiral feed track 3 is formed. The lower surface of the vibrating bowl 2 is equipped with an electromagnet that generates electromagnetic vibrations for transporting parts, a vibrating plate spring that supports the bowl and converts the vibrations into transportable vibrations, and a controller. Therefore, when the electromagnet is energized, the capacitor 4 stored in the vibrating bowl 2 can be delivered along the feed track 3 from the inside to the outside.

Therefore, at the outlet end of the feed track 3,
A parts sorting device, generally designated by numeral 5, is arranged,
This parts sorting device 5 is equipped with a sorting ring 6 commonly called a cornice wheel, and a plurality of pocket grooves 7, 7, . There is. The size of these pocket grooves 7 is set to be large enough to accommodate the main body of an electronic component such as a capacitor 4 in a lying position. That is, the main body 8 of the capacitor 4 is accommodated in the pocket groove 7 in a horizontal position, and the anode lead 10a is
This is a posture in which the cathode lead 10b and the cathode lead 10b protrude outward in the radial direction. Incidentally, the anode lead 10a and the cathode lead 1 of the capacitor 4 treated according to the present invention
The lengths of the legs are different from that of the anode lead 10a, and the anode lead 10a is normally set to be longer than the cathode lead 10b.

The sending ring 6 is placed on a table 11 of a vibrating bowl feeder, and is given a rotational movement in the counterclockwise direction shown by the arrow when vibrating. As a result, a large number of capacitors 4 are stuck in the pocket grooves 7, 7, .
It will be rotated and transferred in a counterclockwise direction.

According to the present invention, the orientation of the polarities is adjusted by the posture correction device 12 disposed on one area of the feeding ring 6 so that the cathode lead 10b with the short leg length always leads in the direction of movement.

The posture correction device 12 has a hook rod 14 that acts only on the long anode lead 10a. A portion 14c is provided. The support part 14c
is fixed to the bottom surface of the tip of a bracket plate 15, and this bracket plate 15 is fixed so as to protrude outward from the upper end of a restraining plate 16. This holding plate 16
is a sector-shaped plate disposed in a predetermined area of the sending ring 6, and is provided to prevent the capacitors 4, 4, . . . , 4 passing through this area from floating upward.

A segment-shaped first magnet 17 is disposed on the path along which the short cathode lead 10b of the capacitor 4 moves and above the locking portion 14a of the hook rod 14.

This first magnet 17 acts on the short-legged cathode lead 10b to attract the cathode lead 10b upward, and in this embodiment, it is made of a permanent magnet such as magnetic rubber. There is.

On the other hand, the first magnet 17 and the hook rod 14
A second magnet 18 is disposed below the locking portion 14a and radially outward. This second magnet 18 attracts the long-legged anode lead 10a of the capacitor 14 downward to create an anode lead 1.
This is for applying braking force to 0a.
Further, a third magnet 19 is arranged near the outlet end of the second magnet 18 and at a position radially inward. This third magnet 19 is
The cathode lead 10b acts on the cathode lead 10b, which is disposed on the moving path of the cathode lead 10b of the capacitor 4 and passes through the outlet end of the first magnet 17.
The cathode lead 1 always works to attract 0b.
It functions to advance 0b.

Note that the capacitor leads 10a and 1 are attracted by the permanent magnets 17, 18, and 19.
It is very easy to move the condenser 4 in the direction perpendicular to the direction in which the shunt ring 6 attracts the condenser 0b.

A converting device 20 for converting the orientation of the capacitor 4 from the lying position to the standing position is disposed downstream of the posture correcting device 12. This conversion device 20 has a deflection plate 21, and a deflection surface 22 is formed on a part of the periphery of the table 11 from near the entrance to the center of the deflection plate 21, and the capacitor 4 has an anode lead 10a and a cathode lead 10b.

The polarities of the leads are uneven, and in some cases the anode lead 10a is ahead in the direction of movement, and in other cases the cathode lead 10b is ahead. In any case, as the transfer ring 6 rotates in the direction of the arrow, the long anode lead 10a of the capacitor 4 moves in the circumferential direction in the direction of the arrow while being hooked on the lower surface of the locking part 14a of the hook rod 14. be transported. During this time, the cathode lead 10b of the capacitor 4 moves upward while being attracted by the first magnet 17. At the moment when the cathode lead 10b comes off the first magnet 17, the third magnet 19 attracts the cathode lead 10b in the forward direction.On the other hand, the attraction force of the magnet 18 acts as a brake on the anode lead 10a. It acts like a multiplier.
