Inline weight inspection of running tread profiles for passenger and truck tires

The dimensionCONTROL TMWI 8302.LC system is suitable for the inline weight inspection of continuous running rubber profiles (tread pattern or sidewalls) for passenger and truck tires. Based on the force measurement principle, the inspection system uses two load cells which measure the deflection of the measurement conveyor. These sensor elements are attached to a massive construction, which ensures a long-term mechanical stability of the system. The measurement conveyor uses precise and balanced aluminum rollers with special surface treatment. This ensures a low deadweight, avoids influence of unbalance and eliminates material sticking. Data obtained from the load cells are processed in the implemented PLC cards which determine the measured weight mathematically.The software included offers a variety of measurement data processing, definition of design profiles, statistical analysis of measured profiles and diagnostic tools.

Advantages

•  Ideal for precise inline weight inspection of running tread profiles for passenger and truck tires
•  Adjustable extrusion head/controllable extruder
•  Automatic profile sorting and remote access
•  Ideal for harsh environments prevailing in the preparation area due to its robust design

Technical parameters

•  Measuring range: weight up to 10 kg/m
•  Weight accuracy < ±1 g (static); < ±5 g (dynamic)
•  Length of the weighing conveyor: 500 m

Measuring the tire profile width in extrusion lines

The dimensionCONTROL TWI 7303.I tire width inspection system is designed for profile width measurement in extrusion lines. This measuring system is based on camera vision technology involving two cameras inside one measurement box. These cameras are angle mounted to each other and operate according to stereo vision technology which enables high precision measurements in the whole calibration range.

Advantages

•  Precise measurements in harsh environmental conditions (e.g. vibrations, unpredictable material movements on conveyor in material flow direction, in vertical directions or even combined)
•  Simultaneous measurement of two produced profiles
•  Automatic detection, measurement and profile evaluation
•  Visualization software offers database containing the measured profiles, recipes, tools for static processing and for export of different output formats

Material parameter

•  Tire width from 350mm to 550mm

Service centers and cutting lines

In cutting lines such as slitting shears and cut-to-length shears, final quality control of the material to be supplied is an advantage. In addition to deciding whether the cut sheet or cut ring meets the requirements, the measuring systems from Micro-Epsilon also allow complete documentation and logging of the production.

One of the advantages of the C- and O-frame measuring systems of the thicknessCONTROL MTS 8201/8202 series becomes particularly clear in this area. The high lateral resolution of discrete laser lines enables both thickness measurements as well as width and cambering detection.

Thanks to a flexible mechanical concept, O-frames can be equipped with a different number of thickness measurement channels. This allows a wide variety of measurement modes to be implemented.

•  Traversing thickness profile measurement with one measuring channel and virtual longitudinal profiles
•  Thickness measurement at the edge and in the center along the sheet with 3 thickness measurement channels
•  Thickness measurement at the edge and in the center of the sheet and additional thickness profile measurement with 4 thickness measurement channels
•  Up to 3000 mm with O-frame
•  Independent of surface, material and alloy

Long products

Long products such as profiles, billets, etc., which are produced by rolling, drawing or forging, often have complex cross-sectional geometries. DimensionCONTROL measuring systems are used for geometrical inspection of long products. Depending on the application, these can be equipped with ThruBeam sensors, red and blue laser profile scanners to provide the optimal solution for the application. The systems operate with impressive precision even under the toughest hot rolling conditions. Integrated, fully automatic calibration compensates for the temperature-related, potential long-term drift of the mechanical structure.

The dimensionCONTROL MPG 8208 and MPG 9208 systems are designed as horseshoe frames and generate real 3D data with which the target values are calculated.

Thanks to Micro-Epsilon's broad sensor portfolio, the thickness measuring systems can be customized for further measurement tasks or to compensate for influences on the mechanics due to temperature or mounting tolerances.

•  Measuring range up to 500 mm
•  Real 3D measurement with axis correction of potentially curved targets
•  Compact design for easy integration into the line
•  Comprehensive software package for monitoring and optimizing production
•  Can be equipped with ThruBeam sensors, red or blue laser line profile sensors
•  Pneumatic protection of sensor optics, optional water cooling
•  Flexible interface for communication with production
