Title:
METHOD AND DEVICE FOR DETECTING OPERATIONAL FAILURE IN CASTING LINE
Document Type and Number:
WIPO Patent Application WO/2019/064726
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a detecting method and device with which it is possible to detect the location of an operational failure in a casting line using a minimal impact sensor, in a casting line for castings. An impact sensor (42) is attached to at least one molding flask (14) or surface plate truck (16), an impact value is measured while the casting line is operating, the measured impact value and the measuring position thereof are stored in association with one another and are compared with past impact values at the same measuring position, and a position at which a unique impact value is detected is identified as an operational failure location. Alternatively, impact sensors (41), (49) are attached respectively to a roller conveyor and to a surface plate truck transporting frame (27), the measured impact values are stored in association with the molding flask or the surface plate truck passing by the attachment position of the impact sensor, and are compared with past impact values to detect an operational failure.
