1. A computer-implemented method for the partial emptying of buoyant objects, which are stored in a loading aid having at least one opening, via controls output by a control computer, the method comprising:
establishing, by the control computer, a processing weight that is a weight of objects that is intended to be emptied out of the loading aid;
determining, in a first weighing, a fill weight of the objects in the loading aid via at least one weighing cell;
at least partially immersing the loading aid in water in a bath via a computer-controlled lifting carriage;
positioning or moving the loading aid in the bath via the computer-controlled lifting carriage for a retention time, the retention time predefined as a function of the fill weight and of the processing weight, the positioning or moving of the loading aid in the bath performed such that there is an on-average constant flow of the water in the bath relative to the loading aid and such that the opening of the loading aid is disposed at least partially below a fill level surface of the water in the bath, wherein the positioning or moving of the loading aid in the bath during the retention time causes a portion of the objects to empty out of the loading aid and to be taken along by the flow of the water, the portion of the objects being an actually emptied emptying weight that was emptied out of the loading aid during the retention time; and
lifting the at least partially emptied loading aid out of the bath via the computer-controlled lifting carriage after the retention time has elapsed.
