Abstract
A natural frequency vibratory conveyor which substantially improves upon the slow starting and stopping times and the power requirements associated with prior art natural systems is disclosed. The conveyor employs a drive member reciprocatively connected at one end to a drive motor assembly and resiliently connected at the opposite end to the conveyor platform. The conveyor can be operated at unusually high natural frequencies of vibration, thereby achieving high production rates, by employing opposed, adjustable springs to establish a high bidirectional spring rate between the conveyor platform and the base. Undesirable vertical components of vibration can thus be reduced without sacrificing productivity due to the high natural frequency.
