Abstract

A maintenance management system for a press line which enables even one person to carry out efficient maintenance operations. For this purpose, in the maintenance management system, a communication cable for a network is laid inside the press line with a management computer being the starting point, and a connector capable of being connected to a communicable device is placed in at least one predetermined location on the communication cable. A portable input/output terminal, which is connected to the connector, incorporates software for optionally detecting and displaying maintenance information in the management computer, and which allows an operator to operate the software, is included. In response to a request command for detection and display from the portable input/output terminal, the management computer provides the corresponding information from the maintenance information to the portable input/output terminal

Claims

1. A maintenance management system for a press line including a management computer having maintenance information of the press line therein and producing a display of said maintenance information in response to a request of maintenance personnel to thereby control maintenance management,

wherein a communication cable for a network is laid on each peripheral device, control device and driving device which are installed inside said press line in a way that said management computer is the starting point of the communication cable and a production management computer is at the end of the communication cable;

and

wherein a connector capable of being connected to a device communicable via said communication cable is placed in at least one predetermined location on said communication cable,

said maintenance management system further comprising a portable input/output terminal, which is connected to said connector, incorporates software for optionally detecting and displaying said maintenance information in said management computer by communications via said communication cable, and which allows an operator to operate said software, and

in response to a request command for detection and display from said portable input/output terminal, said management computer providing the corresponding information from said maintenance information to said portable input/out terminal which outputs the request command,

wherein said management computer installs a web server.

2. The maintenance management system for the press line in accordance with claim 1,

wherein said connectors are placed at a plurality of predetermined locations on said communication cable.

3. The maintenance management system for the press line in accordance with claim 2,

wherein each of said portable input/output terminals is connected to each of said plurality of connectors.

4. The maintenance management system for the press line in accordance with claim 2,

wherein said portable input/output terminals are connected to said plurality of connectors when necessary.
