Title:
金属中空体の個別追跡方法
Document Type and Number:
Japanese Patent JP5618996
Kind Code:
B2
Abstract:
The invention relates to a method for the individual tracking of metallic hollow bodies, in particular hot-fabricated steel tubes, wherein following a final step of hot-work the individual tube is provided with a distinctive identification on the tube circumference, which is read in the feed region to the subsequent manufacturing or test stations automatically as a video image during transport and independently from the direction of transport. According to the invention, the labeling of the tube circumference is carried out in at least two segment-like sections, the tube circumference being divided, wherein the labeling is carried out in segments with a rotation of less than 360 DEG of the numbering unit and the segments comprise an axial offset relative to the longitudinal axis of the tube, which is greater than the width of the data matrix code.
