Conveying system

1. A conveying system comprising:

a robot apparatus having a holding portion configured to hold a package, and an arm configured to move the holding portion, wherein the robot apparatus is located next to a first conveyor extending in a first direction, in a second direction, which is different from the first direction;

a second conveyor located next to the robot apparatus, in the first direction, and configured to convey the package in the second direction toward the first conveyor, the second conveyor being located between a first accumulation portion and the robot apparatus in the first direction;

a third conveyor located next to the robot apparatus, on an opposite side of the second conveyor with respect to the robot apparatus, and configured to convey the package in the second direction toward the first conveyor; and

a controller configured to control the robot apparatus so as to retrieve the package from the first accumulation portion for the package and place the retrieved package on the second conveyor, wherein

the controller controls the robot apparatus so as to retrieve the package from a second accumulation portion for the package and place the retrieved package on the third conveyor,

the third conveyor is located between the second accumulation portion and the robot apparatus in the first direction,

in a case in which the package does not satisfy a first condition, the controller controls the robot apparatus so as to place the package on a package recovery portion, and

in a case in which the package does not satisfy the first condition, the controller controls the robot apparatus so as to place the package on a fourth conveyor extending toward a package recovery portion.

2. The conveying system according to claim 1 , wherein, in a case in which the package does not satisfy the first condition, the controller controls the second conveyor such that the second conveyor is rotated in reverse, so that the package placed on the second conveyor is conveyed to a package recovery portion.

3. The conveying system according to claim 1 , wherein, in a case in which the package does not satisfy the first condition, the controller controls the second conveyor such that the second conveyor is rotated in reverse, so that the package placed on the second conveyor is conveyed to a fourth conveyor extending toward a package recovery portion.

4. The conveying system according to claim 3 , wherein the fourth conveyor is located next to the second conveyor, on an opposite side of the first conveyor with respect to the second conveyor.

5. The conveying system according to claim 1 , further comprising:

an inclined table located next to the first conveyor, inclined such that a height thereof decreases toward the first conveyor, and configured such that the package that is to be supplied to the first conveyor is placed on the inclined table.

6. The conveying system according to claim 5 , wherein

the inclined table has a first portion and a second portion that is farther from the first conveyor than the first portion is, and

an inclination of the second portion relative to a horizontal plane is greater than an inclination of the first portion relative to the horizontal plane.

7. The conveying system according to claim 5 , wherein the inclined table comprises an arc portion projecting diagonally downward.

8. The conveying system according to claim 5 , wherein, in a case in which the package satisfies a second condition, the controller controls the robot apparatus so as to cancel holding of the package in a state in which the package is inclined toward a direction that extends along the inclined table, above the inclined table.

9. A conveying system comprising:

a robot apparatus having a holding portion configured to hold a package, and an arm configured to move the holding portion, wherein the robot apparatus is located next to a first conveyor;

a second conveyor configured to convey the package toward the first conveyor; and

a controller configured to control the robot apparatus so as to retrieve the package from an accumulation portion for the package and place the retrieved package on the second conveyor, and to control the second conveyor such that, in a case in which a package satisfies a first condition, the second conveyor is rotated forward, so that the package is conveyed to the first conveyor, and, in a case in which a package does not satisfy the first condition, the second conveyor is rotated in reverse, so that the package is conveyed to a package recovery portion.

10. A conveying system comprising:

a robot apparatus having a holding portion configured to hold a package, and an arm configured to move the holding portion, wherein the robot apparatus is located next to a first conveyor;

a second conveyor configured to convey the package toward the first conveyor; and

a controller configured to control the robot apparatus so as to retrieve the package from an accumulation portion for the package and place the retrieved package on the second conveyor, and to control the second conveyor such that, in a case in which a package satisfies a first condition, the second conveyor is rotated forward, so that the package is conveyed to the first conveyor, and, in a case in which a package does not satisfy the first condition, the second conveyor is rotated in reverse, so that the package is conveyed to a third conveyor extending toward a package recovery portion.

11. A conveying system comprising:

a robot apparatus having a holding portion configured to hold a package, and an arm configured to move the holding portion, wherein the robot apparatus is located next to a first conveyor extending in a first direction, in a second direction, which is different from the first direction;

a second conveyor located next to the robot apparatus, in the first direction, and configured to convey the package received from the conveyor, in a direction away from the first conveyor; and

a controller configured to control the robot apparatus so as to convey the package conveyed by the second conveyor, to an accumulation portion for the package.
