BoardProfiler 3D-T
BoardProfiler 3D-T - high density tranverse conveyor board scanning
Overview
The BoardProfiler 3D-T provides very high-density board scanning on transverse conveyors for grading, sorting or optimisation of the trim saw process. This high definition scanning ensures that the true shape is accurately captured and means that the best possible yield can be achieved. The system uses the latest high-resolution 2D laser technology developed by LIMAB which scans every millimetre of the board. The system can easily be retrofitted on an existing line or can be specified for equipping a new process line.
Quick Spec
| Scan density | Scan area per sensor | Scan rate | Thickness accuracy |
| 0.94 x 1 mm (at 1m/sec) | ±0.2 mm | 1000 profiles per second per sensor | <±0.2 mm (±2 Sigma) |
Operating principle
The boards are scanned using a number of our ProfiCura-600 sensors using a technique known as 2D laser triangulation. The sensors mounted every 600 mm and capture a complete cross section every millimetre along the board length. The scanning process enables the computer to generate a very detailed 3D model of each board.
Applications
- Wane and other defect optimisation of the trim saw process
- Deformation measurement, twist, flatness and other shape classifications
- Thickness and width sorting, for dimension and quality grading
ProfiCura technology
The BoardProfiler 3D-T uses LIMAB’s ProfiCura-2D laser triangulation sensors which are a product of 30 years experience of producing precision laser sensors. The sensors very accurate and stable yet suitable for use is a rugged sawmill environment.
Non-contact measurement
The laser measuring principle means that the boards are measured without contact. This means that it can operate on the fastest conveyors and still provide reliable results.
Automated inspection
The BoardProfiler 3D-T will accurately determine the shape characteristics of each board and calculate a cutting proposal based on the customers quality grades. Automating the sawing or trimming operation, reducing manpower and increasing yield.
Automated sorting
The width, thickness and length of each board is measured and compared with predetermined quality grades providing the signals to the drop sorter for automatic sorting of the timber into the correct bins.
Integration with existing sawmill equipment
LIMAB’s long experience in supplying the sawmill industry means that the equipment can be easily be retrofitted to existing lines or fully integrated with new ones. Interfaces available to many of today’s OEM sawmill equipment suppliers.
