Claim of US Patent No. 10,919,706

1. A conveyor apparatus comprising:a conveying unit which conveys an article supplied from the outside;
a detection unit which detects an amount of an article loaded on the conveying unit; and
a control unit which sets a force of conveying the article in the conveying unit on the basis of a detection result of the detection unit and controls an operation of the conveying unit,
wherein the control unit sets the conveying force of the conveying unit to be smaller than a current conveying force when a state in which a change amount of the article loading amount on the conveying unit is smaller than a threshold value is maintained for a predetermined time or more in the detection result of the detection unit, and
the control unit sets the conveying force of the conveying unit to be larger than the current conveying force when a state in which the change amount is smaller than the threshold value is maintained for a first predetermined time or more and sets the conveying force of the conveying unit to be smaller than the current conveying force when a state in which the change amount is smaller than the threshold value is maintained for a second predetermined time or more which is the predetermined time and is equal to or longer than the first predetermined time.
