PROBLEM TO BE SOLVED: To reduce a work load in fraction processing of a package body.SOLUTION: A stacking device comprises: a feed conveyor 4 for transporting package bodies 10 in which beverage containers are packed, and transporting a final package body 10A to which a fluorescent ink is applied as the final package body 10; a palletizer 2 for stacking the package bodies 10 transported by the feed conveyor 4; a control part 6 for controlling the palletizer 2; and a detection part 27 for radiating light to the package bodies 10 being transported by the feed conveyor 4, detecting fluorescence of the fluorescent ink by the radiated light, thereby detecting the final package body A. The control part 6 performs stacking processing for stacking the package bodies 10 per a unit of a predetermined number by the palletizer 2, until the detection part 27 detects the final package body 10A, and when the detection part 27 detects the final package body 10A, performs fraction processing for stacking the package bodies 10 to the final package body 10A by the palletizer 2. |
