This magnet 6 is a permanent magnet and exerts a magnetic force on the magnetic lead frame 7 made of a ferrous material that slides along the frame guide surface of the frame guide seat 5.
The lead frame 7 is braked by the resistance force against the inertial fly of the lead frame 7.

し、ｌピッチ分のフレーム送りが終了する。Next, book lI! The action of koji example will be explained. When transporting the lead frame 7v along the 7-frame guide surface of the frame guide sheet 5, the feed pawl 8 operates in a rectangular shape as shown by A1-A4 to perform pitch feeding. That is, A
, the feed pawl 8 moves horizontally within the groove 9 of the frame guide sheet 5 to a predetermined position below the lead frame 7. In operation A, the feed pawl 8 rises in the vertical direction and hooks the feed pawl 8 on the outer frame portion of the lead frame 7. After that, the feed claw 8 pulls the lead frame 7vA in the direction of the frame guide surface K with the action of
IB means sliding. When this frame feeding operation is performed by a predetermined pitch, the feeding claw 8 is lowered by the operation A4, and the frame feeding by l pitch is completed.

ていることにより、オーバーランを生じることはない。In this frame feed operation Haruka@, there is a risk that an overrun of 1 feed may occur at the end of the operation of A, but in this embodiment, the operation of A is neutralized by lead frame 7Y: below it. Since the feed pawl 8 feeds the lead while being attracted by the magnetic force of the magnet 6 on the side, even if the feed pawl 8 descends and separates from the lead frame 7, the lead 7 frame 7 is attracted by the magnet 6 and will not overrun. will not occur.
なお、磁石６ｔ−電磁石で構成し、送り爪８の矩形動作

よう忙しても、同様に良好な効果が得られる。It should be noted that even if the magnet 6t is composed of an electromagnet, the timing is matched with the rectangular movement of the feed pawl 8, and the magnetic force is applied only when necessary, a similar good effect can be obtained.

である。As described above, according to the present invention, the magnet is embedded within the transport surface of the transported article, so that the transported article will not be damaged by contact with the magnet, and the appearance will be improved.
It is possible to improve the quality without causing any problems, and it is possible to reliably prevent overruns of incoming goods. Furthermore, even if the article to be sent has some burrs, it can be stably fed without being affected by the burrs, and there is no need to replace the magnet.
