ABSTRACT:
An automatic conveying apparatus has a lower conveyor, an upper conveyor, and a distribution conveyor. The upper conveyor is associated with a first photoelectric sensor, and the lower conveyor is associated with a second photoelectric sensor. A workpiece delivered from a transfer press at a first speed V.sub.1 is fed onto the distribution conveyor which is actuated also at the first speed V.sub.1. After the first photoelectric sensor or the second photoelectric sensor is turned on by the workpiece until it is turned off, the workpiece is conveyed at a second speed V.sub.2 greater than the first speed V.sub.1 by the distribution conveyor. The workpiece is transferred from the distribution conveyor to the lower conveyor or the upper conveyor which is actuated at the second speed V.sub.2.
