Coe Newnes/
McGehee

The Coe Newnes/McGehee (CNM) Double Length Infeed (DLI) system offers the latest technological advances in primary log breakdown. Knowledge gained from delivering 700+ optimizers has been applied to the log optimizer decisions. High scan density and the unique positioning of laser profile sensors greatly enhance the quality of the optimizer’s decisions.

Among the many features offered is dynamic chip head control that allows the heads to follow the mid-point of the log (regardless of sweep or diameter) independently for both faces, so that the chip heads are always in the best position for quality chips and surface finish. The use of motion control ensures superior turning, skewing and positioning accuracy.

The system includes an Auto-Rotation conveyor that accommodates side or end loading from the log decks. The rotated log is re-scanned to ensure cutting tools are set to achieve the highest possible recovery. The scanning software incorporates a complete solution for all products that can be produced downstream. CNM provides complete systems— mechanical, controls and optimization.

Comact Inc

Comact OLI-CS3 is the newest way to optimize more. The rotation tracking of the infeed systems assures an ultra precision log rotation, confirmation and continuous correction of the log. The conventional concepts disappear after the log turner, giving way to revolutionary “optimized length” technology. While the log is in the turner, a true-shape “confirmation scanner” located immediately downstream of the turning rolls continuously monitors the outside profile of the log to confirm its position and make the correction required, and the log is perfectly fed to the infeed where true shape scanners re-scan the log and optimize it for maximum recovery over a full rage of type combinations.

Porter Engineering

RT3, Real Time for Real Trees with Real Shape, is Porter Engineering’s newest generation primary log breakdown system. RT3 incorporates higher definition scan data, using multi-point laser modules and the latest VMEbus processors to provide accurate true shape log profiling for increased recovery and value from each log over earlier X-Y scanning systems.

Just a few of the features include: a full profile laser camera co-planar scanner; full cant, sideboard and top board combinations using Real Log shape; the flexibility to enter lumber sizes in US, metric, or a combination of both; and many more.

RT3 allows “single log” and “complete shift” simulation, using Real Log measurements captured to disk. Simulations can occur at any time, even as logs are being processed, to determine the effect of changing any parameter (price, target size, kerf, product mix, etc) without affecting the actual logs.

USNR

USNR’s innovative Knuckle Turner Infeed combines the functions of a log turner and a double length infeed into a single compact machine. Because the turning mechanism is integrated into the feed system, the Knuckle Turner Infeed is capable of rotating, slewing, and skewing logs, reducing real estate and capital requirements, while providing outstanding throughput and recovery.

The guts of the Knuckle Turner Infeed are seven pairs of spike-rolls and fluted rolls, three of which pivot. Acting in unison, the rolls rotate, slew, and skew logs as specified by USNR’s Mill-Wide optimization software, insuring that logs are oriented so that downstream machine centers extract the maximum value from the resource.

The Knuckle Turner Infeed is particularly well-suited to small log applications where speed is essential to attain sufficient throughput, but the technology is applicable to any high volume operation.

Sawquip

Sawquip’s CCO Log Infeed is said to be unique to the industry. Top and bottom spiked horizontal rolls are mounted on sideways and positioned by servo-cylinders controlled by the optimizer.

Scanners located inside the infeed transmit live data of a log’s position, and corrections are made instantaneously until the optimized longitudinal sawing axis is attained before the log reaches the chipping heads.

Coupled to this is an extremely fast quad roll log turner that has been rated by Forintek Canada as having the lowest turning error of all units they have evaluated.

Other major advantages include compactness (17.5’ for 16’ logs), total log control by the rolls as it enters the chipping heads and the “chainless” benefits such as low maintenance, less wear and no misalignment.

The end result has been four units sold and value recovery improvements of 10 to 15 per cent.

Rockwell Industries Ltd

Feed speed and lumber recovery are the life and death functions of primary breakdown equipment. However, ease of maintenance, which minimizes downtime, is just as important. Breakdown positioning is a result of accurate scanning, and a log or cant that is bouncing, rocking or surging during scanning will result in misleading information being given to the PLC and the set works.

Rockwell Industries has put special emphasis on the log and/or cant control during this process, both in the initial design of a new machine and the upgrade addition to an existing canter line. The best way to gain control is to add control, i.e. additional feed rolls and/or press rolls. Remember, speed means nothing without control.

MPM

MPM Engineering is developing a rotation verification system, which will check the accuracy of the turning solution in an auto rotation installation. If the log has been over-turned or under turned, the MPM software will correct the rotation before the log exits the log turner. Accuracy is within +/- 5 degrees.

MPM Engineering has received an order for bucking software from Microtec, a scanning manufacturer based in Brixen, Italy for a project with Arauco in Chile.

The order has been taken with profile scanning but is to be upgraded with x-ray scanning in the future. MPM will also upgrade their software when the x-ray scanner is installed. Microtec has already installed several x-ray scanners into sawmills in Europe for testing and development. A commercial model will be available soon.
