## Abstract

An article sorting and conveying device that conveys articles by the vibrations of a movable body provided through an elastic support unit, includes a first vibration unit that imparts a periodic vibration force to the movable body in a direction inclined from a vertical direction; a second vibration unit that imparts a periodic vibration force in a direction crossing the periodic vibration force by the first vibration unit; and a vibration control unit that causes a periodic vibration force imparted by each vibration unit to have a phase difference and occur simultaneously at the same frequency, and that creates an elliptical vibration trajectory in the movable body. 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.

## Claims

### Claim 1

An article sorting and conveying device that is provided with a movable body provided on a substrate through an elastic support unit and that conveys the articles loaded on the movable body by the vibrations of the movable body, comprising:
a first vibration unit that imparts a periodic vibration force to the movable body in a direction inclined from a vertical direction;
a second vibration unit that imparts a periodic vibration force to the movable body in a direction crossing the periodic vibration force by the first vibration unit;
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
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.

### Claim 2 (depends on 1)

The article sorting and conveying device according to claim 1, wherein
a guide that moves the sorted articles along a predetermined trajectory is provided on the movable body.

### Claim 3 (depends on 1)

The article sorting and conveying device according to claim 1, wherein
a vibration switching unit that switches the vibration trajectory of the movable body with a different vibration trajectory is provided such that the vibration switching unit internally stores data of a phase difference according to which articles having a different coefficient of friction are conveyed in a different direction, and data of a phase difference according to which articles having a different coefficient of friction are conveyed in the same direction, which constitutes the phase difference of the periodic vibration force by each of the vibration unit, and also switches the phase difference in accordance with a signal input from outside.

### Claim 4 (depends on 2)

The article sorting and conveying device according to claim 2, wherein
a vibration switching unit that switches the vibration trajectory of the movable body with a different vibration trajectory is provided such that the vibration switching unit internally stores data of a phase difference according to which articles having a different coefficient of friction are conveyed in a different direction, and data of a phase difference according to which articles having a different coefficient of friction are conveyed in the same direction, which constitutes the phase difference of the periodic vibration force by each of the vibration unit, and also switches the phase difference in accordance with a signal input from outside.

### Claim 5

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.

### Claim 6 (depends on 5)

The article sorting and conveying device according to claim 5, wherein
the movable body is configured by:
a lower movable bench arranged downward of the intermediate bench;
a conveyance bench arranged upward of the intermediate bench and including the conveyance surface; and
a connecting member that connects the lower movable bench and the conveyance bench.
