Robot machining system having supply and discharge conveyor belts and pallets

A work forming apparatus comprising:

• a robot which is driven within a predetermined operational range;
• working means including a chuck located within said operational range;
• a supply loop constituted by a conveying closed loop including a work supplying section located within said operational range;
• a discharge loop constituted by a conveying closed loop including a work discharging section located within said operational range;
• a plurality of supply pallets disposed on said supply loop for accommodating different kinds of material works, said supply loop conveying said supply pallets to and from said work supplying section;
• a plurality of discharge pallets disposed on said discharge loop for accommodating different kinds of formed works, said discharge loop conveying said discharge pallets to and from said work discharging section;
• each of said supply pallets and said discharge pallets having information recording means thereon, each of said information recording means being arranged to record work information relative to a corresponding pallet including any latest work information;
• a first information processing head disposed at said work supplying section for reading required work information from the information recording means provided on a one of said supply pallets located at said work supplying section and writing the latest work information to said information recording means;
• a second information processing head disposed at said work discharging section for reading said work information from the information recording means provided on a one of said discharge pallets located at said work discharging section and writing the latest work information to said information recording means;
• and
• control means comprising means for inputting a production command, means for circulating said supply loop and said discharge loop so that a particular supply pallet which accommodates material works of a kind according to said production command and a particular discharge pallet which accommodates formed works of a kind according to said production command are located respectively at said work supplying section and said work discharging section on the basis of work information on said supply pallet read by said first information processing head and work information on said discharge pallet read by said second information processing head, means for driving said robot to take a required material work out of said supply pallet located at said work supplying section and attaching said material work to said chuck of said working means, means for causing said working means to form said attached material work, means for driving said robot to remove a formed work from said chuck of said working means, and means for positioning said removed work in said discharge pallet located at said work discharging section.
