Abstract:

According to the requirements of the feature and the measurement accuracy in roller shape detection process, a roller shape detection method is proposed, which uses reflective optical fiber sensor to do nontouch photo electricity detection for roller shape. By detecting the changes of the reflective ray position on roller’s surface accurately, the tiny changes of the radius of the roller can be magnified and converted to some beeline displacement. And by measuring the beeline displacement, which is proportion to the radius of the roller, the roller shape can be measured in a nontouch distance detection method precisely. A simulationsoftware program is compiled with Microsoft Visual Basic 6.0 based on this principle. By using this simulationsoftware, the date of output signals of this system can be gained in time. And the curve of detection signals of the roller shape can be drawn automatically by this software. Our proposal is a nontouch high precision detection method for roller shape, providing high magnification, low cost and easy realization.
