Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an alarm management device for a sheet metal working machine, which is applied to a sheet metal working machine including an NC device, for example.

[0002]

2. Description of the Related Art Generally, an alarm generated by a cause during operation of a sheet metal working machine equipped with an NC device is generated by an NC device, a servo system of a sheet metal working machine body, and a sequencer ( Ladder) that occurs in the. Further, regardless of whether the alarm is generated by the NC device, the servo system, or the sequencer, the alarms are classified into EM, alarms (in a narrow sense), warnings, interlocks, etc. in descending order of urgency.

A sheet metal working machine equipped with a conventional NC device is provided with appropriate alarm detecting means for detecting various alarms when these alarms occur, and when the alarm detecting means detects an alarm, the alarm is detected. The contents are displayed in a message.

[0004]

However, in such a conventional device, when the alarm detecting means detects an alarm and displays the content of the alarm by a message, in that state,
The alarm detection operation by the alarm detection means stops. For example, if any one alarm is detected and its content is displayed as a message, no other alarm is detected unless the state is terminated.

Therefore, for example, when a machine stops due to several causes, even if an alarm message is displayed, the message is intended for only one alarm included in the cause, and the one Alarms are not always the primary cause of machine downtime. As a result, the machine may not be able to resume operation because the root cause has not been resolved even if the prescribed action is taken for the alarm for which the message is displayed. There were many problems, such as another alarm message being displayed.

An object of the present invention is to eliminate the problems of the above-mentioned conventional ones, to monitor various alarms generated in a sheet metal working machine, and to display a message for any number of generated alarms. An object of the present invention is to provide an alarm management device for a sheet metal processing machine.

[0007]

SUMMARY OF THE INVENTION The present invention is to solve the above problems. The invention according to claim 1 is to provide an alarm monitoring means for constantly monitoring various alarms of a sheet metal working machine, and the alarm monitoring means. When the alarm monitoring means detects the occurrence of an alarm, it stores the message data for each of the various alarms monitored by the A message processing unit that selects message data corresponding to the alarm from the various message data stored in the message storage unit and displays the message data on a screen, and a predetermined message on the screen on which the message data is displayed. Until the termination operation is performed, the alarm monitoring means monitors the alarm and the message is displayed. An alarm management unit for sheet metal processing machine to continue the display of the message data corresponding to the generated alarms di processing means.

According to a second aspect of the present invention, there is provided alarm monitoring means for constantly monitoring various alarms of the sheet metal working machine, and various alarms monitored by the alarm monitoring means.
Message storage means for storing various predetermined message data for explaining each content, cause of occurrence, and coping method, and when the alarm monitoring means detects an alarm, the message storage means stores the message data in the message storage means. Message processing means for selecting and displaying on the screen the message data corresponding to the alarm from among the various message data described above, and alarm history saving means for saving the occurrence history data of the alarm detected by the alarm monitoring means. And continuing to display the alarm data by the alarm monitoring means and the message data corresponding to the generated alarm by the message processing means until a predetermined ending operation of the screen on which the message data is displayed, Switch off this message data display screen By obtaining an alarm management apparatus for sheet metal processing machinery was capable of displaying occurrence history data of alarms stored by the alarm history storage unit.
