計量器の寿命検出装置

Device for detecting lifetime of weighing instrument

Abstract

PROBLEM TO BE SOLVED: To estimate more accurately the lifetime of a part, by incorporating not only the conditions such as a rotational speed of a machine part, frequency, operation speed, and so forth, but also a weight detection function of a weighing instrument into a lifetime estimation calculation. SOLUTION: A load cell 4e for measuring the weight of a material to be weighed, an arithmetic processor 12 for calculating the lifetime of a bearing of a conveyor pulley 4f on the basis of a measured value by the load cell 4e, and an alarm device 14 for issuing an alarm when the calculated value by the arithmetic processor 12 reaches to a lifetime setting value are provided.
