Article classification method and article classification device

When an article (A) is made to travel in an inclined conveying direction (C), an article transverse pushing body (4) that moves in a main conveying direction (T) and that is provided so as to be movable freely in a width direction (W) orthogonal to the main conveying direction (T) is used, the article transverse pushing body (4) is accelerated in the width direction (W) in a distribution region (B) and then is moved inertially, and the article transverse pushing body (4) that is moved inertially is brought into contact with the article (A). 使用沿主输送方向(T)移动并且沿与主输送方向(T)正交的宽度方向(W)移动自如地设置的物品横推体(4)，在使物品(A)沿着倾斜输送方向(C)行进的情况下，使物品横推体(4)在分配区域(B)沿宽度方向(W)加速之后惯性移动，使该惯性移动中的物品横推体(4)与物品(A)接触。
