Abstract
An elevated grade station drive system includes a plurality of conveyor sections for conveying workpieces downstream at a variable transfer speed along and between the plurality of sections according to control instructions provided by a control system. The output from at least one workpiece position sensor cooperates with corresponding upstream conveyor sections and provides workpiece position data to the control system. Each conveyor section has a corresponding variable frequency drive cooperating in variable speed driving engagement therewith. The control system controls each variable frequency drive so as to interlock adjacent conveyor sections for smooth translation of the workpieces between adjacent conveyor sections without crushing or binding the workpieces. The plurality of conveyor sections may include a plurality of lugged conveyors, which may be lugged chains.
