The systems belonging to the TGI 8302.LLT fam- ily are equipped with three application-specific triangulation laser scanner. They reliably detect the radial and axial unbalance as well as bulges and constrictions on the tire. Therefore, they make an important contribution regarding reli- ability and quality during the production of the tire, one component of the vehicle which is rel- evant to high safety in the automotive and com- mercial vehicles production.
Three laser line scanner are integrated in the TGI 8302.LLT. Using those profile sensors, the whole surface is scanned, bulges and constrictions are detected in angles, lateral size and depth. Efficient signal processing algorithms ensure reliably letter elimination. Additionally, the ra- dial and lateral unbalance of the tire subject for inspection is detected. This value is evaluated as average value, peak-to-peak value. Further- more, the vibration behaviour is shown.
The mechanical basis of TGI 8302.LLT is a C- frame in which the upper and lower flange as well as the tread sensor are controlled accord- ing to the tire size due to full-automatic control- ling methods. The actuators can be alternatively operated by servo or step motors. The control- ling parameter can be stored in the database.
Using laser line triangulation sensors which are optimised regarding the installing situation for the application in measuring system for tire geometry, the systems can be applied in vari- ous existing TU machines. Due to the special arrangement of optics, they have an excellent ratio of line length and measurement range to installation space
