Self-contained multi-mode vibratory feeder control with unitary delay adjustment

摘要

A vibratory power control having all of the electronics for feedback control of a vibratory parts feeder in a single unit with a fiber-optic cable for remote sensing of parts feeding and a single control adjusting both on delay and off delay of the feeder. A mode switch for selecting on delay, off delay, or dual delay; a sensor polarity switch, and a wired-OR sensor input are provided so that the improved electromagnetic noise immunity of the self-contained design is obtained with a coincident increase rather than decrease in system flexibility.
