<p>The invention relates to a method for unloading a container, said container (K) including an elastic bag (2) containing granular material (M). According to the invention, in the method:
- the container (K) complete with the bag (2) is arranged on an unloading surface (10), provided with unloading means (3);
- the first end (Ka) of the container, and the outlet aperture (22; 221) provided at the second end of the bag (2) , i.e. its discharge end, are opened;
- the employed unloading element (3) is a spiral conveyor (30) comprising a conveyor pipe (31) and a conveyor screw (32) arranged therein, said spiral conveyor being fitted, before the unloading step proper, in the outlet aperture (22) provided at the other end of the bag (2), so that the spiral conveyor extends to the interior (2a) of the bag, and to the material (M) contained therein;
- whereafter the material (M) is conveyed out of the bag along the conveyor pipe (31) by using the spiral conveyor (30); and where
- as the unloading proceeds and the bag is emptied, the unloading surface (10) together with the container attached thereto and provided with the bag (2) and the unloading element (3) can be lifted to an inclined position (C) with respect to the longitudinal direction of the container, so that the first end (Ka) of the container and the discharge end of the bag are positioned lower than the other end of the container, in which case material contained in the bag can be transferred, by means of gravity, to the discharge end of the bag and unloaded by the unloading element. The invention also relates to an arrangement for unloading a container suited for the method.</p> |
