Abstract
A shaker conveyor assembly for moving objects includes a conveying element adapted for movement in first and second directions in repeated rectilinear fashion so as to convey items placed on the conveying element in one of the directions. The assembly includes an electric drive assembly having an output, a control assembly, and at least one sensor adapted to sense movement of the output. The control assembly provides a first level of electrical power to the electric drive assembly during a first portion of reciprocal movement and a second level of power to the electric drive assembly during a second portion of reciprocal movement. In addition, the control assembly provides selective control over the duration of the first and second portions of the reciprocal movement thereby controlling the speed of each of the directions of reciprocal movement of the conveying element.
