Vibration conveyor and method for regulating a vibration drive of a vibration conveyor

Abstract

The vibration feeder has a drive unit comprising a vibration drive, a carrier arrangement comprising a feeding element for the material to be conveyed and a control for the vibration drive, wherein an acceleration sensor is arranged on the drive unit, which when the vibration feeder is operating, detects the actual acceleration of the drive unit, and wherein the control is configured to use the actual acceleration signal of the acceleration sensor for generating a regulating variable for the vibration drive such that the carrier arrangement vibrates essentially within its resonance frequency (fres). This makes it possible, during operation, to detect the acceleration of a drive unit of the vibration feeder and to generate therefrom a regulating variable for a vibration drive such that a carrier arrangement of the vibration feeder vibrates closer to its resonance frequency (fres) or is brought back again to the same. In addition the inventive control may be used to also regulate the amplitude of the carrier arrangement and the associated mass flow m to a required value.
