Abstract: PURPOSE: To enable the automatic positioning of a container by a method wherein a supporting region of a rocker bearing in a supporting structure is displaced to the rear as the container travels forward and an advance in relation to the material-release mechanism is released by the displacement in the center of gravity when filling materials in a container and then, the container is controlled again. CONSTITUTION: A container 4 is moved in the direction of F and advanced until the excessive weight at the left side of a rocker bearing 10a becomes an adequate brake force in a brake 12. Since the rocker bearing 10a can be moved along tracks 14a and 14b, the rocker bearing 10a is moved along the tracks as the container 4 is advanced. When carrying out the filled container 4 by a belt conveyor 18, the movement of a container 4' is controlled according to an advance of the container 4 by the belt conveyor 18. If the container 4' which is not subject to the excessive weight and not press-fitted by a brake 12 is driven by its self-weight and if a folding cardboard box 8 is filled in the container 4', the excessive weight is tilted as if the container 4 were pressed to the brake 12.
