Abstract
Abstract An automatic article working system particularly suitable for limited production of a variety of articles. The system comprises a plurality of pallets for loading articles to be worked, each of the pallets being used as a member for conveying the articles to be worked between machine, tools, pallet conveyor means, pallet storing means located on both sides of the pallet conveyor means, and pallet transfer means adapted to move a pallet in and out of the pallet storing means. A plurality of machine tools are adapted to work the articles, and manipulators are provided to convey the articles to be worked from a pallet which has been removed from the storage means to the machine tools and to return worked articles back to the pallet. A computer is operatively connected to all of the means to effect control thereof.
