<p>PURPOSE:To prevent the occurrence of a human work mistake by moving a defective work at the stage to a correcting loop outside the line without stopping the procession of the line when a work defect detection signal is generated, and returning the corrected work to the next stage of the proceeding line. CONSTITUTION:Correcting loops 11, 12 are provided near the outside of a main line 1, and correcting loops 13, 14 are provided on the outside of sub-lines 2, 3 respectively. When the defective assembling of a work w34 to a work W4 is detected at a stage S3, for example, the work W4 and work w34 are moved to the correcting loop 11, the work data of the next work W5 are set to the stage S3, and the work is performed when the work W5 proceeds. The work W4 corrected in the correcting loop 11 is returned to the next stage S4 which is vacant in the main line 1, and it proceeds to the following stages on the main line 1.</p> |
