Article sorting and conveying device

An article sorting and conveying device, comprising:

• a substrate;
• an intermediate bench that is elastically supported relative to the substrate by a plurality of first rod-shaped springs provided almost parallel and at an inclination with respect to a vertical direction;
• a movable body that is elastically supported relative to the intermediate bench by second rod-shaped springs provided almost parallel to the first rod-shaped springs, and on top of which is formed a conveyance surface on which the articles are loaded and conveyed;
• a first vibration unit and a second vibration unit each of which imparts a periodic vibration force from the intermediate bench side to the movable body in a first direction and a second direction that cross each other and are perpendicular to a longitudinal direction of the second rod-shaped springs;
• and
• a vibration control unit that controls each vibration unit to cause a periodic vibration force imparted by each vibration unit to have a phase difference and occur simultaneously at the same frequency, and to create an elliptical vibration trajectory in the movable body, wherein
• a center of gravity of the movable body is configured to almost match the center of gravity of the intermediate bench, and
• the articles are sorted and conveyed on the movable body by setting the vibration trajectory of the movable body by the vibration control unit such that articles having a different coefficient of friction are conveyed in different directions.
