System for predicting life time of grinding roller of heddles polishing device

The present invention is always the material of the heald and then to be detected by using a proximity sensor formed the dalneun degree of abrasive grinding when the grinding rolls of a roll of heald polishing apparatus in multiple stages, automatically adjusting the position of the grinding rolls the state grinding in contact with the surface of a thin plate or a punching process heald to occur, and the polishing roll life prediction of the heald polishing apparatus to notify has rapidly outside the operator when to be replaced with all the service life of the grinding rolls It relates to the system. The invention Polishing roll which is driven by the rotating electrical machine grinding operation in order to achieve the above object; The grinding roll is formed on both sides of the sheet material of the heald is mounted, rotating roller to the sheet is rotated in contact with a polishing roll condition; Support springs for preventing and formed to support the lower side of the thin sheet metal is bent by roll grinding; Proximity sensor for detecting the respective spaced-apart location of the lower and the polishing is to form a multi-stage polishing of the rolls; Presented a grinding roll by controlling parts of the drive motor through the signal values ​​transmitted through the said proximity sensor operating lifting and grinding roll life predicting means for alarm lamp, causes warning sound output control according to the replacement timing, and the polishing amount of the polishing roll; It is coupled to the drive motor and the grinding rolls that are rotated by applying a control signal to the normal rotation or the reverse rotation drive motor unit consisting of a ball screw of the abrasive roll is operational, up and down lifting by the rotational force of the drive motor; consisting heald polishing apparatus in basically predicts the lifetime of the polishing roll when OFF signal value received from the last proximity sensor proximity sensor formed by the multi-stage portion alarm output to be set, but, by using the operation keys provided on the outside of the polishing roll life predicting means It relates to a grinding roll life predicting system of the heald polishing apparatus including a lifetime prediction steps according to the grinding roll life prediction set to set separate parts.
