ABSTRACT:
An orientation system forms part of a magnetic core handling system using an oscillating feed cup causing magnetic cores to roll across an arcuate surface into a tapered slot and communicate with an index feed wheel. The index feed wheel has 50 slots formed around the edge thereof, each slot being in communication with a vacuum line to engage and hold the edge of the cores with the open center portion being exposed for testing. The index wheel is controlled without bounce through the use of a permanent magnetic stepping motor. The motor is controlled through four series of pulses for different field phases of the motor to control its movement. A single standard split pin probe is used for testing the magnetic cores and the probe does not come in contact with the core. A storage memory system is used to determine whether the core tested previously a plurality of slots from the accept or reject sorter determines the reservoir into which the cores will be collected. A detector is used on the probe drive mechanism to control the position of the index wheel.
