Shaker conveyor assembly having an electronically controllable stroke speed
First Claim
1. A shaker conveyor assembly for moving objects, said assembly comprising:
- a conveying element adapted for movement in first and second directions in repeated rectilinear fashion so as to convey items placed on said conveying element in one of said directions;
an electric drive assembly having an output operatively interconnected between said electric drive assembly and said conveying element;
a control assembly and at least one sensor operatively connected in electrical communication with said control assembly, said sensor adapted to sense movement of said output; and
said control assembly in electrical communication with said electric drive assembly and adapted to selectively provide a first level of electrical power to said electric drive assembly during a first portion of said reciprocal movement of said conveying element and a second level of power to said electric drive assembly during a second portion of said reciprocal movement of said conveying element, said control assembly further adapted to provide selective control over the duration of said first and said second portions of said reciprocal movement thereby controlling the speed of each of said directions of reciprocal movement of said conveying element.

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.
