US 6,725,116 B2 · Production management system

Abstract

In production management system of a vehicle, at a parts assembling step, a computer terminal 12 reads the product-specific information and the parts-specific information from an information storage medium 2 through an information read/write unit 3. On the other hand, a bar-code reader 5 reads the product-specific information (e.g., the vehicle code) from the completion check indicator 4 of a vehicle body 1 and the parts-specific information and the parts-intrinsic information from parts 6. And, the computer terminal 12 compares the product-specific information with each other and the parts-specific information with each other and writes, when both the individual comparisons are coincident, the parts-intrinsic information in the information storage medium 2 through the information read/write unit 3 to allow the parts 6 to be assembled in the vehicle body 1. When either of the comparisons results in incoincidence, on the other hand, a warning of incoincidence is issued from a warning unit 7 to avoid the assembly of the parts 6.

Dependent claims

A production management system for a vehicle for assembling parts in a target product on the basis of an information storage medium recording the product-specific information of said product and the parts-specific information of said parts, comprising:

medium information reading unit for reading said product-specific information and said parts-specific information from said information storage medium;
product-specific information reading unit for reading the product-specific information from an actual product;
parts-specific information reading unit for reading the parts-specific information from the parts to be actually assembled, and for reading the parts-intrinsic information intrinsic to individual parts;
and
comparison output unit for recording said parts-intrinsic information in said information storage medium when the information read by said product-specific information reading unit and the information read by said parts-specific information reading unit are coincident to the information read by said medium information reading unit, and for comparing the information read by said product-specific information reading unit and the information read by said parts-specific information reading unit, with the information read by said medium information reading unit, to output the comparison result.
