A line production management system is provided. In the line production management system, a primary computer, a primary controller, a secondary controller, a tertiary controller and a number of processing machines are provided. The primary controller maintains work files containing work sequence data defining the classification, work priority and quantity of the work objects to be processed, and transmits the work file information through a communication network. The secondary controller generates and maintains correlation files to correlate each work sequence data included in the work files information with the codes which determine each processing to be applied to each work object in each work station, and transmits the correlation files through the communication network. The tertiary controller generates step files based on the work files and correlation files received through the communication network. The step files contain processing instruction data for each work station. In each work station, the processing machines are automatically controlled according to the processing instruction data received from the tertiary controller.

Line production management system

An automated production line monitoring system is presented to provide; setting and control of process parameters necessary to operate the various automated processing machine units installed on the line; and surveillance of abnormalities which may occur in the line. The line operator, working in a centralized CRT display and control center, monitors CRT screens showing: an operational preparation display consisting mostly of output signals from various sensors; an operational mode display showing a table of control switches; an interlock display showing various interlocked machine units; a product-type display showing processing steps to be performed on current product; an abnormality list display showing causes of various abnormalities on the line; a status display showing the operating conditions of various machine units; step monitor display showing the sequential step numbers of a production cycle; unit stepping display showing the details of the respective steps shown in the unit stepping display. The operator is able to control the operation of the entire line from the monitoring center by examining relevant displays and rapidly identifying causes of problems on the CRT screen.

Monitoring system for automated assemblies

An automated system of managing a group of frame numbers to identify each vehicle in different vehicle model groups is provided. This system comprises a first computer which creates frame number groups and a production ratios of various model vehicles to be produced according to an assigned production schedule; a second computer which takes these frame numbers and organizes them according to the production ratio and serialized numbers to be stamped; and a stamping machine to display and stamp the serialized frame numbers automatically on frame components. Accordingly, the operator is able to check the frame numbers easily with minimum human errors so as to preserve data integrity and stamping errors. This system is also applicable to mixed production of large number of models using a common assembly line.
