Abstract

Ferrite cores are fed from vibratory feed bowl 10, drawing A, onto probes 12, mounted on the periphery of revolving probe wheel 14. Air retention system 16 maintains the cores on probes 12 and includes an upper air brush 18 and a lower air brush 20. A cross-section of air brush 18 is shown in B. Brush 18 includes air supply tube 22 feeding air to a first expansion chamber 24 and then in turn to a second expansion chamber 26. Continuous slot 28 leading from chamber 26 lies radially outwardly of the path of travel of probes 12 providing a continuous air stream onto the cores to overcome the centrifugal force that tends to throw the cores off such probes. At test 30, lower air brush 20 is reduced in diameter as in B. Otherwise, brush 20 is similar in cross-section to 18 and includes its own air supply tube 32.

Ferrite Core Air Retention System

Ferrite cores are fed from vibratory feed bowl 10, drawing A, onto probes 12, mounted on the periphery of revolving probe wheel 14. Air retention system 16 maintains the cores on probes 12 and includes an upper air brush 18 and a lower air brush 20. A cross-section of air brush 18 is shown in B. Brush 18 includes air supply tube 22 feeding air to a first expansion chamber 24 and then in turn to a second expansion chamber 26. Continuous slot 28 leading from chamber 26 lies radially outwardly of the path of travel of probes 12 providing a continuous air stream onto the cores to overcome the centrifugal force that tends to throw the cores off such probes. At test 30, lower air brush 20 is reduced in diameter as in
B. Otherwise, brush 20 is similar in cross-section to 18 and includes its own air supply tube 32. When a probe 12 carrying a ferrite core passes the end of brush 20, the core falls from the probe into an accept or reject slot in accordance with the test performed at station 30.
