Abstract
A conveyor, which has an area in its conveyor line and for adjusting intervals between articles, includes (1) a plurality of zones constituting the area and each having at least one driving motor and an article sensor, (2) structure for measuring either an interval between adjacent articles in the conveying direction or a difference of time points when adjacent articles in the conveying direction pass the sensor, and (3) a motor controller for each of the zones and for varying a rotational speed of the driving motor. When the measuring structure measures either the interval or the difference upon reception of signals from the sensor, the motor controller either accelerates or slows down the rotational speed of the driving motor in a zone where the article is placed.
