ProfiCura Dim

ProfiCura Dim - cup, wane and width measurement in sawmills

Overview

The new LIMAB ProfiCura Dim is a smart sensor using our latest 2D laser technology that measures the geometrical dimension of a board in both transversal and linear processes. ProfiCura Dim measures the cup, wane and width of the board simultaneously.  All calculations are done within the sensor and measurement results are directly communicated from the sensor on Ethernet or a variety of Fieldbus interfaces. The sensor measures and calculates the cup or wane orientation and board width.  Board vibration, movement, colour and moisture do not influence the measurement. The system will provide a signal to the turn the board depending on the cup or wane orientation. The installation is very simple and the single sensor is easily retrofitted on existing lines keeping cost low.

Operating Principle

The ProfiCura Dim uses our latest generation laser sensor that uses the principle of 2D laser triangulation to capture the actual profile of boards.  A laser line of length 500 mm is projected onto the board this line is viewed with a matrix camera. This technique allows the entire board profile to be captured in a single shot.

Applications

  • Wane turning – Detection of cup orientation before planing.
  • Wane turning – Detection of wane orientation before nailing machine in pallet process.
  • Wane turning – Turning signal for wane orientation before edger or rip saw
  • Width measurement – in a sorting line

ProfiCura Dim sensor mounting

The sensor is mounted above the conveyor at a safe stand off distance of 750 mm. No other processor is required, the ProfiCura Dim will process the board profile and output directly the board cup status directly to the line PLC. This means installation is simple keeping costs low.
