US 2004/0002788 A1 · Parts supplying system of assembling production line and supplying method of the same

Abstract

The invention makes it possible to efficiently and accurately supply parts to a work in an assembling production line structured as a mixed assembly line, and to improve a flexibility of changing the line. A parts supplying system of the assembling production line is provided with a working instruction server which takes in a production order information corresponding to an optional number of works, extracts the same type of works in a unit of a lot so as to sort in an order of a parts preparing work, and generates a working instruction information including a parts preparing work order, a number of the lots and an assembly parts information per the types, set containers which receive assembly parts sets to be assembled in one work, a parts setting area which has a working station provided with parts shelves for the assembly parts, and inputs the assembly parts set for the corresponding type of work to each of the set containers in the order of the parts preparing works by a unit of the same type lot, on the basis of the working instruction information, and a replacement buffer which returns each of the set containers from the parts setting area to an order of the type in accordance with the production order in the assembling production line so as to input to the assembling production line.
