Abstract

A production process control system, which includes a production process control server controlling production process information of a product and a control terminal controlling production operation of a production facility connected with the production process control server via a network, is equipped with a production process information data base being a data base of the production process information of the product; an information recording means in interruption receiving the production process information data base in interrupting production operation on the way of a production process of the product, and storing the production process information data base; and a search means searching production process information stored by the information recording means in interruption from the production process information data base in restarting interrupted production operation.

Claims

1. A production process control system which includes a production process control server controlling production process information of a product and a control terminal controlling production operation of a production facility connected with said production process control server via a network, the system comprising:

a production process information data base being a data base of the production process information of said product;

an information recording means in interruption which when interrupting production operation on the way of a production process of said product, receives production process information in interruption from said control terminal and stores the production process information in said production process information data base; and

a search means searching the production process information stored by said information recording means in interruption from said production process information data base in restarting interrupted production operation,

wherein said control terminal comprises a production process restarting means controlling said production facility so as to perform the production operation based on said production process information in interruption searched by said search means in restarting the interrupted production operation when a production process taken charge by the control terminal is not completed.

2. A production process control system according to claim 1, wherein when a defect occurs on the way of production, production operation is interrupted.

3. A production process control system according to claim 1, wherein when a change of a production plan of said product occurs on the way of production, production operation is interrupted.

4. A production process control system according to claim 1, wherein when a change of a production scheduling of said product occurs on the way of production, production operation is interrupted.

5. A production process control system according to claim 1, wherein when a change of production control of said product occurs on the way of production, production operation is interrupted.

6. A production process control system according to claim 1, wherein when a change of production control of said product occurs on the way of production, production operation is interrupted.

12. A production process control system according to claim 1, wherein when a defect occurs on the way of production, production operation is interrupted.

15. A production process control method according to claim 1, wherein when a change of a production scheduling of said product occurs on the way of production, production operation is interrupted.

16. A production process control method according to claim 1, wherein when a change of production control of said product occurs on the way of production, production operation is interrupted.

7. A production process control method which controls a production process by a production process control server controlling production process information of a product and a control terminal controlling production operation of a production facility connected with said production process control server via a network, the method comprising the steps of:

an information recording step in interruption in which when interrupting production operation on the way of the production process of the product, said production process control server receives production process information in interruption from said control terminal and stores the production process information in a production process information data base;

a search step in which when restarting interrupted production operation, said production process control server searches said production process information stored by said information recording step in interruption from said production process information data base; and

a production process restarting step in which when restarting the interrupted production operation, a control terminal controls the production facility so as to perform the production operation based on said production process information in interruption stored by said search step in the case that a production process taken charge by the control terminal is not completed.

8. A production process control method according to claim 7, wherein when interrupting production operation on the way of a production process of a magnetic tape cartridge, for a work having entered a servo write process in interruption, operation is performed till an impress process, and in completion of the impress process, the work is removed from a line and kept;

and for a work finished till the servo write process, after a finish of a process in interruption the work is removed from said line and kept.

9. A production process control method according to claim 8, wherein when a defect occurs on the way of production, production operation is interrupted.

10. A production process control method according to claim 8, wherein when a change of a production plan of said product occurs on the way of production, production operation is interrupted.

11. A production process control method according to claim 8, wherein when a change of a production scheduling of said product occurs on the way of production, production operation is interrupted.

13. A production process control method according to claim 7, wherein when a defect occurs on the way of production, production operation is interrupted.

14. A production process control method according to claim 7, wherein when a change of a production plan of said product occurs on the way of production, production operation is interrupted.

17. A production process control method according to claim 7, wherein when a change of design of said product occurs on the way of production, production operation is interrupted.

18. A production process control method according to claim 7, wherein when a change of design of said product occurs on the way of production, production operation is interrupted.
