Abstract

Magnetic cores are tested while carried on the end of a plurality of radial arms 9 attached to a rotary turret. After being tested, the cores are blown, by an air jet, into a sorting mechanism. The latter has oscillatory member 10 that carries tubes 11 ad 12. These receive cores from arms 9 and transfer them into bins 13 and 14. Armature 15 is carried by member 10 and it is attractable alternately to electromagnets 16 and 17 in accordance with which electromagnet is energized. Tubes 11 and 12 are shaped so that when either electromagnet 16 or 17 is energized, the cores are directed into bins 13 ad 14 respectively.

Sorting Mechanism for Magnetic Core Tester

Magnetic cores are tested while carried on the end of a plurality of radial arms 9 attached to a rotary turret. After being tested, the cores are blown, by an air jet, into a sorting mechanism.

The latter has oscillatory member 10 that carries tubes 11 ad 12. These receive cores from arms 9 and transfer them into bins 13 and
14. Armature 15 is carried by member 10 and it is attractable alternately to electromagnets 16 and 17 in accordance with which electromagnet is energized. Tubes 11 and 12 are shaped so that when either electromagnet 16 or 17 is energized, the cores are directed into bins 13 ad 14 respectively.

Electromagnets 16 ad 17 are energized in synchronism with movement of cores from the test station ad in accordance with whether or not each core passes the test. Each electromagnet is energized by a input signal which provides a current of a first relatively high magnitude sufficient to pull in the armature and transfer it from one electromagnet to the other. Then the input signal is decreased to a lower magnitude sufficient to hold the armature.

Due to one cause or another, such jamming of member 10 by a core, tubes 11 and 12 fail to move into the proper position for receiving cores from arms 9. In order to determine this lack of a transfer, the output of each electromagnet is fed to an interrogate circuit. Due to the dependency of the electromagnet energizing current on armature position, a dip 18 appears in...
