EDGER OPTIMIZER TECHNOLOGY OPTIDRIVE

HIGH PERFORMANCE EDGER OPTIMIZER TECHNOLOGY

Optidrive from EWD is the fastest edger in its class. The optimisation determines
the best edging solution, by volume or value, using the stored product dimensions,
qualities and prices and optionally by product priorities.en.

The OptiDrive infeed table uses driven positioning heads and pressure rollers to
achieve previously unattainable high-availability acceleration values.

The feed speed of the system is set automatically at maximum according to the load.

Unscrambling

The supplied boards are singulated in an S-shaped chain transverse transport. Adjustable
ejector cams automatically kick out the leading board when it is double-occupied so that
it slips off.

Sensors for monitoring and automatic control of the unscrambler guarantee high availability
and effectiveness. After unscrambling, a cascade system with toothed chains and patented
EWD stop hooks follows.

For troubleshooting, the feeding conveyors can reverse and transport products back to the
unscrambler.

The board measurement

The board profile is scanned in linear or transverse transport by an optical measuring system.
Both sides of a board are automatically scanned and the length and position of the wane is
analysed. A wane allowance can be entered as percent or absolute value, separately for the
left and right side.

Option: top and bottom mounted quality scanner.

The functionality

The supplied boards are singulated in an S-shaped chain transverse transport. Adjustable
ejector cams automatically kick out the leading board when it is double-occupied so that
it slips off.

Sensors for monitoring and automatic control of the unscrambler guarantee high availability
and effectiveness.

After unscrambling, a cascade system with toothed chains and patented EWD stop hooks
follows.

For troubleshooting, the feeding conveyors can reverse and transport products back to the
unscrambler.

For transverse-scanning systems, board scanners of different designs can be implemented
in this area. Their data can then be entered into optimization systems with customer-specific
targets.

The OptiDrive infeed table uses driven positioning heads and pressure rollers to achieve
previously unattainable high-availability acceleration values.

The main functions of edging optimization

• Choice of lumber species and quality
• Input qualities
• Thicknesses with qualities

Input of allowed wane per quality possible.

The optimization determines the best edging solution, by volume or value, using the
stored product dimensions, qualities and prices, and optionally by product priorities.

All parameters can be modified while the machine is operating.

The feed speed of the system is set automatically at maximum according to the load
or can be limited if desired.

An integrated diagnostic software with VPN access enables quick assistance for service
calls and troubleshooting.

eWood

eWood is a comprehensive optimisation and application software from EWD. All modern
EWD sawlines and machines share the same eWood user interface.

The interface man – machine offers an intuitive and consistent user concept, allowing
effective use of the functions after just a short training period.
