Production management system
First Claim
1. A production management system for controlling a production line having a plurality of assembling/machining stations including pieces of production equipment, comprising:
- a computer for supply control information to control the pieces of production equipment;
a first information network for transmitting the control information from said computer to the assembling/machining stations, wherein said first information network comprises a plurality of separate networks associated respectively with divided portions of said production line, each of said separate networks including a plurality of assembling/machining stations; and
a second information network for transmitting information indicating results of a completed operation in the assembling/machining stations to downstream assembling/machining stations to allow defective portions of workpieces to be repaired in the subsequent assembling/machining stations.

Abstract
A production management system controls a production line having a plurality of assembling/machining stations including pieces of production equipment such as nut runners. The production management system includes a computer for supplying control information to control the pieces of production equipment, a first information network for transmitting the control information from the computer to the assembling/machining stations, and a second information network for transmitting information indicating results of operation in the assembling/machining stations to downstream assembling/machining stations to allow defective portions of workpieces to be repaired in the subsequent assembling/machining stations. The first information network comprises a plurality of separate networks associated respectively with divided portions of the production line.

2. A production management system for controlling a production line having a plurality of assembling/machining stations including pieces of production equipment, comprising:
-
an information network for interconnecting the assembling/machining stations; display means in the assembling/machining stations, for displaying results of a completed operation in the assembling/machining stations; detecting means associated with the pieces of production equipment, for detecting proper and improper completed operations on workpieces in the assembling/machining stations and transmitting data on the detected proper and improper completed operations from upstream assembling/machining stations to the display means in downstream assembling/machining stations through said information network; and control means for controlling said display means in the downstream assembling/machining stations to successively display the data on the detected proper and improper completed operations from the detecting means in the upstream assembling/machining stations in synchronism with arrival of the workpieces at the downstream assembling/machining stations. - View Dependent Claims (3, 4)

5. A production management system for controlling a production line having a plurality of assembling/machining stations including pieces of production equipment, comprising:
-
an information network for interconnecting the assembling/machining stations; display means in the assembling/machining stations, for displaying results of a completed operation in the assembling/machining stations; detecting means associated with the pieces of production equipment, for detecting proper and improper completed operations on workpieces in the assembling/machining stations and transmitting data on the detected proper and improper completed operations from upstream assembling/machining stations to the display means in downstream assembling/machining stations through said information network; entering means associated with said display means, respectively, for entering chronological data on repairs effected on workpieces based on the data displayed by said display means; and control means for controlling said display means in the downstream assembling/machining stations to successively display the data on the detected proper and improper completed operations from the detecting means in the upstream assembling/machining stations and the chronological data from said entering means in synchronism with arrival of the workpieces at the downstream assembling/machining stations. - View Dependent Claims (6)

7. A production management system for displaying results of a completed operation effected by pieces of production equipment, comprising:
-
detecting means associated with the pieces of production equipment, for detecting results of a completed operation on workpieces by the pieces of production equipment and transmitting data on proper completed operation when it is effected on the workpieces within a predetermined period of time and data on improper completed operation otherwise; and display means for displaying configurations of the workpieces and locations on the workpieces in different colors depending on the data on proper and improper completed operations on the workpieces. - View Dependent Claims (8)

9. A production management system for controlling a production line having a piece of production equipment to operate on a workpiece based on operation pattern data, comprising:
-
detecting means associated with the piece of production equipment, for detecting data on a result of a completed operation on the workpiece by the piece of production equipment; and control means for producing the operation pattern data, said control means comprising comparing monitor means for comparing a time-dependent change in the data from said detecting means with a predetermined value, and means responsive to an output signal from said comparing monitor means, for producing a signal indicative of an inspection or a repair to be made with respect to the piece of production equipment. - View Dependent Claims (10)
