Patent ID: 7793772

Claim:
A conveyor line segment having a predetermined length for accumulating several conveyed goods thereon comprising: a conveying means for moving the conveyed goods thereon at a substantially constant speed along the segment in a conveying direction oriented parallel to a longitudinal direction of the segment; a sensor to detect conveyed goods transported onto the segment; and a controlling unit coupled to the sensor in order to move and stop the conveying means, dependent on the detection signal of the sensor, and which is adapted to determine a geometrical length of incoming conveyed goods in the conveying direction, and to not move the conveying means further, dependent on the respectively determined length, if the segment cannot take additional conveyed goods any more, wherein the controlling unit comprises a calculation unit which sums the lengths of all the conveyed goods conveyed onto the segment and a predetermined minimum distance in order to determine whether the segment can receive other conveyed goods.
