Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a work management device for presses and other automatic machines.

For example, when automatic press processing is performed, once operation has started, the operator is free to perform other tasks.
Of course, during normal operation, the line will continue to operate automatically even if there is no worker, and if the line needs to be stopped, the worker can stop it at his/her discretion. Also, during Private Luck Δ, it is possible to detect some kind of abnormality and stop driving. In this case, the operator can continue automatic operation by correcting the abnormal part and restarting the machine. As described above, the method of detecting abnormality and stopping the line is well known and has been used in the past. However, if such an abnormality occurs only once or twice, the operating efficiency of the line is not a problem, and the operator can memorize it to some extent. However, such abnormalities may occur several times a day, and in addition, even if the operating conditions are normal, the fins may stop due to setup changes, etc. In such cases, the overall operating rate is significantly reduced, and it is also very difficult for workers to remember the reasons for line stoppages. Moreover, even if it were possible to memorize it, it would be quickly forgotten unless it was preserved as data. This is the reason why it is extremely difficult to manage and increase the operating rate (operating efficiency) of the line per second when performing automatic press processing.

The present invention solves the above-mentioned problems, and when press working or other various types of work are performed automatically, it checks and judges each part of the equipment and starts and stops the work. The purpose of the present invention is to provide a device that records various data such as work status, reason for stoppage, and production quantity on a printed tape over time.
