Abstract

PURPOSE:To prevent the residence of conveyed material and facilitate the maintenance by providing under a bin a cylindrical vibration table having a guide portion in the center, a discharge port at the periphery, and a bottom, and by applying up and down and twisting vibrations in combination to the table. CONSTITUTION:A vibration table 14 with the same diameter as that of a bind 10 is provided under it. When vibration motors 21, 21 are operated, the material in the bin 10 is vibrated and conveyed along a bottom plate 14a and is discharged outward through a discharge port 25 in sequence. The discharged quantity of the material is controlled by changing the frequency or amplitude of vibrations of motors 21. According to this device, the residence of the material in the bin is prevented and the material is prevented from being broken because no rotating mechanism exists in the table 14, and in addition, the maintenance is facilitated because no mechanical portion exists in the table 14.
