Accordingly, loading work is simplified by way of saving troubles and time for reshuffling of a large number of the supply means 1 to supply various kinds of the required articles 2 and for changing steps for the industrial robot 4. Additionally, direction of the articles 2 is changed as required by a reversing mechanism. Consequently, it its possible to improve loading work efficiency and to simplify article supply work.
