3. Operating
Principle
NTN bowl feeder
is designed to magnetically vibrate a bowl and a lower vibrator coupled to each other
with a leaf spring set at a certain angle of inclination. As a result of this rotary vibration, works are aslant in
the upward direction in the bowl to go forward little by little. The relationship between the bowl and the
leaf spring is so set that the vibration may be nearly resonant to the suction frequency of the vibration
magnet. Accordingly, a large vibration can be put forth with small exciting force.

(Note)
The actual structure may be different from the illustration shown above because of reasons such
as different shapes of bowl and controller and absence of the bowl internal aux. hopper.
