PURPOSE:To accurately classify objects to be screened to prescribed classifying places by beforehand storing empty cup load and cup numbers, and subtracting the empty cup load from the cup load of the time when an object to be screened is placed on the cup. CONSTITUTION:When a driving part 2 operates, a cup 1 is conveyed, and in the position of the part 2, it goes to the lower side and in the position of a driven part 3, it again goes to the upper side. At the placement point A near the part 3, an object to be screened is placed on the cup 1, and its weight is measured by a weighing device 7. This measured value is sent to a data processor, by which the empty cup load of that cup is subtracted, and the position of the classifier 4 of a receiving box 4 to be classified by the weight of the measured object is determined. At the timing when the cup 1 carrying the object is conveyed up to the position of the prescribed classifier 6, the object is dropped into the receiving box 4. |
