Description

  The present invention relates to an unbalance correction system for correcting an unbalance of a rotating body.

  In the conventional unbalance correction system, first, the first measurement unit B that measures the unbalance amount and position of the rotating body, the correction unit C that corrects the unbalance amount, and the second that checks the unbalance amount after correction. As shown in FIG. 2, these are arranged on the circumference, and a transport loader E that rotates in one direction (clockwise) has a rotating body as a part of these parts B and C. , D in order, the unbalance amount of the rotating body is corrected.

  That is, in FIG. 2, the worker sets the rotating body that has been transported by the conveyor or the like in the loading unit A to the transport loader E. The transport loader E rotates clockwise by approximately 90 degrees. In the first measuring unit B, the rotating body is taken out from the transport loader E, unbalance measurement of the rotating body is performed, and the measured rotating body is returned to the transport loader E. In the correction unit C, the rotating body that needs to be unbalanced is taken out from the transport loader E and returned to the transport loader E after correction. In addition, correction is not performed about the rotating body whose imbalance measurement result in the 1st measurement part B is below a predetermined value. In the second measurement unit D, only the rotating body corrected by the correcting unit C is taken out from the transport loader E, and the unbalance measurement of the rotating body is performed again. In this case, since the unbalance correction is not performed for the rotating body whose unbalance measurement result in the first measurement unit B is a predetermined value or less, the measurement in the second measurement unit D is not performed.
