  • Automated machine installation and method
    Patent number: 4621410
    Abstract: A system comprising a plurality of complementary numerically controlled machine tools in which different work-pieces are each subjected to appropriate selected machining operations on selected machine tools in a selected order by appropriate delivery of common form pallets loaded with the workpieces. Transporters deliver pallets between the machine tools, a storage rack, and work-setting stations where work-pieces, automatically delivered in bins from a bin store, are loaded on pallets. Tool magazines are delivered between a rack and the machine tools by a transporter. Transport and machining operations are computer controled, and monitors feed back signals indicative of location of pallets, tool magazines, and bins in the system.
