Abstract
A material handling methodology for forming cells of material includes a series of mobile telescoping conveyors feeding a mobile bridge conveyor and mobile radial stacker using a set of mobile bridge transfer conveyors. The method involves transferring material from an infeed point to a cell area in a systematic manner that allows for stacking each cell continuously with no interruption to material flow.
Claims19
A system for uninterrupted flow stacking, comprising:
- a first cell area;
- a mobile radial stacker;
- a mobile bridge conveyor having a fore load limit area and an aft load limit area;
- a plurality of mobile telescoping conveyors, each having a head end;
- a first mobile bridge transfer conveyor having a flow output end;
- a second mobile bridge transfer conveyor having a flow output end;
- a first discharge configuration in which the first mobile bridge transfer conveyor is active and the second mobile bridge transfer conveyor is inactive;
- and
- a second discharge configuration in which the first mobile bridge transfer conveyor is inactive and the second mobile bridge transfer conveyor is active,
- wherein the active mobile bridge transfer conveyor is positioned such that material for stacking is conveyed to the mobile bridge conveyor between the fore load limit area and the aft load limit area,
- wherein the system is configured such that the material for stacking is conveyed through the plurality of mobile telescoping conveyors to the active mobile bridge transfer conveyor,
- wherein the system is configured to alternate between the first discharge configuration and the second discharge configuration without interruption to flow of the material for stacking, and
- wherein the system is configured for a first bridge transfer maneuver in which the system is changed from the first discharge configuration to the second discharge configuration, the first mobile bridge transfer conveyor is moved to a position adjacent to the second mobile bridge transfer conveyor, and a last mobile telescoping conveyor of the plurality of mobile telescoping conveyors is removed becoming a removed mobile telescoping conveyor, resulting in a penultimate mobile telescoping conveyor of the plurality of mobile telescoping conveyors becoming a new last telescoping conveyor and an antepenultimate mobile telescoping conveyer of the plurality of mobile telescoping conveyors becoming a new penultimate mobile telescoping conveyor.

A method for forming cells of bulk material with uninterrupted flow comprising:
- locating a system of mobile conveyors along a corridor where the cell is to be created;
- transporting material via the mobile conveyor system to a mobile radial stacker conveyor;
- feeding the mobile radial stacker conveyor with a mobile bridge conveyor;
- diverting flow of the material from a first mobile bridge transfer conveyor positioned at a first end of the mobile bridge conveyor to a second mobile bridge transfer conveyor positioned at a second end of the mobile bridge conveyor such that system material flow is uninterrupted for the duration of the cell creation process;
- positioning the first mobile bridge transfer conveyor adjacent to the second mobile bridge transfer conveyor;
- removing mobile telescoping conveyors from the system as the mobile stacker conveyor retreats and relocating them to a next cell to be stacked;
- and
- diverting flow of the material from the second mobile bride transfer conveyor to the first mobile bridge transfer conveyor as each mobile telescoping conveyor is removed.
