Tire geometry inspection system
The systems belonging to the TGI 8302.LLT family 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 reliability and quality during the production of the tire, one component of the vehicle which is relevant to high safety in the automotive and commercial 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 radial and lateral unbalance of the tire subject for inspection is detected. This value is evaluated as average value, peak-to-peak value. Furthermore, 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 according to the tire size due to full-automatic controlling methods. The actuators can be alternatively operated by servo or step motors. The controlling 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 various existing TU machines. Due to the special arrangement of optics, they have an excellent ratio of line length and measurement range to installation space.
