Arrangement for setting a constant vibration amplitude distribution in the longitudinal direction of the conveying trough or the like of a vibrating conveying device

摘要

Method for setting a constant vibration amplitude distribution in the longitudinal direction of the conveying trough or the like of a vibrating conveying device with an electromagnetic vibration exciter. A constant vibration amplitude distribution is ensured in that at least two vibration exciters (2, 2'), which are distributed in the longitudinal direction of the conveying trough and have in each case an assigned vibration pick-up (4, 4'), are used to operate the vibrating conveying device, in that a first vibration exciter (2) is operated with a specified desired amplitude value and in that the vibration amplitude of the further vibration exciter or exciters (2') is readjusted, by means of the difference between the predetermined desired amplitude value and the vibration amplitude determined by the assigned vibration pick-up (4'), in such a manner that a specified vibration amplitude distribution is maintained along the conveying trough (1). <IMAGE>
