PROBLEM TO BE SOLVED: To apply downward load to each part and prevent noise and vibration due to mutual clearance of respective parts by making the tilting angle of sorting plates in the transverse direction adjustable by vertical displacement of swing supporting rods with which the sorting plates are journalled and adding a mechanism to apply downward load to the lower end parts of the swing supporting rods. ;SOLUTION: Sorting plates 1 whose surfaces are roughened are layered in multi- stages, are journalled with swing supporting rods 2, 3 while being tilted in both vertical direction X and transverse direction Y and enabled to swing slantingly vertically to the transverse direction Y. A supporting axis 4 is projected from the lower end part of the swing supporting rod 3 in the higher position in the transverse direction Y of the sorting plate 1 and the supporting axis 4 is journalled with a bearing 6 fixed in a machine stand 5. Moreover, the swing supporting rod 2 in the lower position is displaced vertically by a tilting angle adjusting means S and the tilting angle of the sorting plate 1 is made adjustable in the transverse direction Y. That is, the swing supporting rod 2 is displaced vertically by fitting a coma 11 at the tip end part of an operation link 10 projected downward in a rotation axis 7 with a motor screw axis 12 by screwing.;COPYRIGHT: (C)1998,JPO
