Conveyor system for high production laser cutting automated system

A conveyor system for use in a laser cutting system for rapidly moving first and second material sheets through a plurality of processing stations, the conveyor system comprising:

• a material storage device having shelves for storing said first and second material sheets;
• a first, a second and a third processing station arranged in this order;
• an endless conveyor that indexes one position at a time through the first, second and third processing stations, the endless conveyor being configured such that at each stop the conveyor has a first section associated with the first processing station, a second section associated with the second processing station and a third section associated with the third processing station, wherein the first, second and third processing stations operate simultaneously on the first, second and third sections of the conveyor, respectively, during a same time period when the conveyor is stopped;
• a loading cart movably attached to the material storage device adapted to load said first material sheet on the first section of the conveyor at said first processing station;
• a drive shaft that moves the conveyor one position at a time forward;
• wherein the endless conveyor comprises a chain member that moves in an endless loop and a plurality of chain covers that are attached to the chain member to protect the chain member from residue generated during a laser cutting process, and that move with the chain member in the endless loop;
• a laser cutting station at said second processing station whereby parts are formed in said first material sheet and leaving a remainder of material;
• and
• a part unloading robot at said third processing station whereby said parts are removed from said first material sheet after it exits said laser cutting station and arrives at the third processing station.
