Vibratory feed method for transporting parts operated at energizing frequency within defined range above or below resonance frequency

摘要

The vibratory feed method as in 10005934.1 uses at least one piezoelectric transducer coupled to at least one electronically-controlled setting element determining the frequency and/or amplitude of the applied signal. The energizing frequency is between 2.5 and 3.5 % of the resonance frequency above the latter or between 4 and 6 % of the resonance frequency below the latter.
