hook and eject it from the E-shaped ejection port 22.

At the same time, the EI type claw portion 49 projects the bottom ■-shaped iron plate 14 from the ■-shaped projection opening 25.

As soon as both ends of the ■ mold iron plate 14 come out of the ■ mold ejection opening 25, they pass under the check brake plate 34 while pushing up the front end thereof, so that they are braked, and the central part is braked by the ■ mold holding member 42. Being held down.

Therefore, the I-shaped iron plate 14 is held down at three points, and both ends advance at the same time, preventing it from becoming oblique.

Since the E-type iron plate 13 carried by the previous stroke of the feed claw 47 is placed at the position where the ■-type iron plate 14 comes off the ■-type receiving plate 23, the I-type iron plate 14 is placed on top of the E-type iron plate 13. The two iron plates 13 and 14 stacked in this way are guided to the side frame 5 and guide rail 18 by the EI type claw part 49, and are sent under the E type iron plate 13 inserted into the coil bobbin 7. It is inserted into the coil bobbin 7 from there.

On the other hand, the E-type iron plate 13 sent by the E-type claw portion 48 is carried to an intermediate position between the case 15 and the coil bobbin 7.

At this time, the tip of the E-type iron plate 13 is connected to the check brake plate 3.
The slide base 45 starts to return when it enters the E-type holding part 51 (FIG. 3) of No. 4, but the E-type iron plate 13
Since the tip of the E-type iron plate 13 is held down by the E-type holding part 51, the E-type iron plate 13 does not move backward.

When the EI type pawl 49 passes under the rear end of the E type iron plate 13, the rear end of the E type iron plate 13 is pushed up and caught on the check part 39 of the check brake plate 34. Retrograde is prevented.

When the EI type claw part 49 has completely passed, the E type iron plate 13
falls onto the guide rail 18.

The above operation is similarly performed on the left side of the coil holding claw 8.8', and the left and right sides are repeated alternately, and the E-type iron plate 13 and I
The iron plate 14 is inserted into the coil bobbin 7.

In addition, when the center leg of the E-type iron plate 13 is bent upward, the E-type holding roller 40 holds it down and prevents it from being inserted on top of the E-type iron plate 13 inserted in the previous stroke. It is something to prevent.

The present invention is not limited to the iron core insertion machine of the type in which the ■-shaped iron plate 14 is inserted into the coil 50 at once after being pushed out of the case as shown in the illustrated embodiment. It can also be applied to a type of iron core insertion machine in which the core is reverse-stopped at an intermediate position by a plate and inserted into the fill by the next stroke of the feed claw.
