PURPOSE:To perform accurate measurement of weights inclusive of those below the prescribed by providing a free weighing device whereby measurement of the weight below the prescribed is conducted by lifting a corrugated cardboard case, in addition to a normal weighing device. CONSTITUTION:An oil-hydraulic device 7 is operated to rotate a feed-out lever 6 in the direction of an arrow (a) and thereby the corrugated cardboard case 1 is sent on to an elevating support 8. The elevating support 8 elevate so as to approach a supplying device 12 located above, with the link levers 10 being erected by the contracting operation of an oil-hydraulic device 11 corresponding to sending-in of the case 1. At the time of elevation of the elevating support 8, a supply-regulating plate 13 is rotated in the direction of an arrow (b) to supply fruit and the like from the supplying device 12 into the case 1. When a prescribed-quantity weighing device 2 on the lower side weighs the supply of a prescribed quantity, the oil-hydraulic device 11 is extended to lower the elevating support 8, while the corrugated cardboard case 1 is sent out by the action of the feed-out lever 6, and another corrugated cardboard case 1 is sent on to the elevating support 8, thus the operating being performed continuously. |
