ProfiCura Cup

ProfiCura Cup - Sawmill cup detection

Overview

The ProfiCura Cup is the simplest and most reliable method of detecting cup in sawmills.  The profile of every board scanned using our latest generation 2D laser technology. The built-in microprocessor calculates the amount of cup and cup orientation and compares with a programmable limit. 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 orientation. The installation is very simple and the single sensor is easily retrofitted on existing lines keeping cost low.

Operating Principle

The ProfiCura Cup is our latest generation sensor that uses the principle of 2D laser triangulation to capture the actual profile of boards.  A laser line of length 300 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

  • Detection of cup orientation before planing.
  • Detection of cup orientation before sawing.

ProfiCura CUP sensor mounting

The sensor is mounted above the conveyor at a safe stand off distance of 950 mm. No other processor is required, the ProfiCura CUP 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.
