PROBLEM TO BE SOLVED: To provide a method and a system in which a package can be inspected precisely without lowering the conveyance capacity of the package by a method wherein a package which is judged to be a defective by a first inspection method is inspected by a second inspection method and the package which is judged to be a defective even by the second inspection method is judged to be a defective package. SOLUTION: A stock line K2 as a stock line for a defective package P2 which is judged to be a defective is installed. A good package P1 which is judged to be a good item by a high-speed rotation inspection as a first ordinary inspection is conveyed as it is. The defective package P2 is stored in the branch line L2. The inspection part of a first inspection station S is divided into a high-speed-of-rotation part and a low-speed-of-rotation part. A package P which is conveyed at the beginning is inspected in the high-speed-of-rotation part. The defective package P2 which is judged to be the defective in a first inspection is inspected in the low-speed-of-rotation part. By this constitution, it is not required to arrange and install a new inspection station so as to be favorable in terms of costs. In addition, since the package P1 which is judged to be a good item is conveyed to a conveyance line L1, the production efficiency of a package is not lowered.
