Title:
STATUS DIAGNOSING SYSTEM FOR ROLLING GUIDE DEVICE, AND STATUS DIAGNOSING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/155136
Kind Code:
A1
Abstract:
Provided is a status diagnosing system which can suitably ascertain the status of a rolling surface of a track member or a load rolling surface of a moving member in a rolling guide device, the system comprising: a sensor (35) that detects a physical quantity when a moving member (2) is moving along a track member (1); and a diagnosis processing unit (39) that takes in an output signal of the sensor and generates analytical data, compares the analytical data with threshold data, determines the presence/absence of an abnormality in the rolling guide device on the basis of the comparison result, and then outputs the result. The diagnosis processing unit includes a first processing mode in which the output signal of the sensor is taken in during a data collection time T1 and then the analytical data is generated, and a second processing mode in which the output signal from the sensor is taken in during a data collection time T2 which is longer than the data collection time T1 and then the analytical data is generated. The diagnosis processing unit outputs the determination result from a combination of the comparison result from the first processing mode and the comparison result from the second processing mode.
