Double Length Infeed Optimiser

Double length infeed optimiser

Features:

• Scanning of logs by C1-Scan True Shape/Full profile scanner to optimise both positioning and cutting of the logs
• Automatic log turner utilising four (4) spiked rolls, controlled by servo positioners
• Self-centering of logs by means of a step flight chain
• Multiple overhead press rolls spaced at 36" intervals to maintain perfect positioning of logs
• Lateral shifting of the double length infeed by means of servo positioners providing perfect centering of logs at the primary breakdown machine
• Recovery improvement approximately of 10% as compared to conventional sharp chain type infeeds

"V" Type Conveyor

Specially designed chain and flights to prevent slippage of the log during both scanning and feeding of the log into the log turner Specially designed V type guide rail to avoid any lateral movement Specially designed for feed speeds up to 600 ft. per min. Full profile C1-Scan provides the log data to allow the high capacity computer to determine the optimised rotation according to the cutting solutions at each 5 degree

SDLI Step Chain Principle

• Positive centering of a wide range of log diameter;
• Better productivity versus sharp chain system that has a small width of contact with the log;
• Top pressroll geometry adapted to control very small logs.

SDLI Side Shift & Skew

According to the reading of the C1-Scan and to the optimised solution of the computer, the double lenght infeed table is side-shifted by means of two servo positioners to provide perfect positioning of the log in the primary breakdown machine or to provide an offset pattern to maximise production. Double length infeed table side shifts on two chromed arbors mounted on SKF Glycodur bushings. • SDLI is supported on two pedestals; • A hydrostatic cushion allows movement in the horizontal plane; • Movement could be a simple Side Shift; • The movement could also be a skewed correction; • Skew is dynamic with log flow
