機械プレス制御における安全確保の論理と方法

概要

Standards have been established by the Japanese Ministry of Labor on the mechanical structure of the power press. These standards provide for the slide to the effect that the power press should be equipped with an overrun monitor function which enables the slide to be forcedly stopped in case the slide fails to stop within a specified allowable range around the upper dead point. This paper regards the press operation as a human-machine system in which both the operator and the machine may cause an error, and defines the overrun monitor function as a requirement for safety operation. Furthermore, this paper establishes a signal processing method for the infallible operation of the overrun monitor function and specifically shows a fail-safe overrun monitoring system based on this signal processing method.
