PREVENTIVE MEINTENANCE METHOD FOR CARRYING SYSTEM

摘要

PURPOSE: To collect failure information of a carrying system and allow performing the quantitative grasp and preliminary countermeasure. CONSTITUTION: Production devices are synthetically controlled by a managerial computer 3, and a transport system 2 consists of a high speed transport device 4. inter-process transport device 5, and a stocket 6 having termorary storing function, wherein error information is recorded in the control device terminal parts 41, 51, 61 of the devices 4, 5, 6. A database 7 is prepared concerning the error information for the overall transport system from the error information records 42, 52, 62 of each device 4-6. Quantitative grasp of the failure situation. extraction of problem point, and inspection and eventual repair are performed based upon the information acquired by the database 7. From the error information accumulated in the database 7, it is practicable to make prediction of error occurrence and its location, cause of the error, quantitative grasp of secular change, grasp of the rate of error occurrence, etc.
