Significant Increases in Production
and Quality using ScanMeg Sensors
The ScanMeg Team has prepared a number of reports and
presentations that enable the Sawmiller to see how the sensors that
we manufactured are specifically engineered for Sawmills, Plywood Mills,
Board Plants and Log-handling Operations.
ScanMeg, with input from some of its good customers, has
developed a secret weapon againstdowntime on canter lines that you can employ to increase
throughput by 3 to 5% by spendingpocket change. You don’t have to send budgets to the Board of
Directors for approval to get aninstant payback simply for redeploying your maintenance dollar
allocation.

Roseburg ForestProducts,
Weyerhaeuser, Tolko, Interfor, Dunkley Limber, Interfor and Abitibi have
increasedthe number of logs per
shift through their primary and secondary breakdown lines through
theuse of some simple

This PowerPoint presentation
will show the specifics of the highly popular BBS+ Single-point, laser
used in combination with a DIFF or differential module, that is used to
monitor board thickness and cant widths. This simple, unique setup can be
placed after all machine centres for a very reasonable cost to check
each and every board or cant at the outfeed. In board plants it can be
used to monitor veneer and plywood thickness. In Reman plants
it can be used to measure wood components.
Used as a single sensor the BBS can
be used for fence verification systems as well as log diameter
determination on Step-feeders to aid in gap control. o More

ScanMeg has
designed a specialized scanner, the Type S, that has a software program
installed in the on-board CPU that recognises wane on a board, and
then outputs a signal to the board turner to turn the board wane
up. The Type S scanner is installed underneath a transfer deck and
monitors all the boards on lugs passing above. It ignores
boards with square edges.
This is ideal
for turning boards in front of the Coe/Newnes/McGehee edger with
their patented "Robo-Guide" mechanism whose scanner requires
all boards be turned wane up. Other uses are just before the
planer infeed to eliminate carpel tunnel syndrome experienced by workers
manually turning boards.

New Backlog-Pressure Scanner to regulate the advance of all transfer
decks between the lug loader, all the way back, and including, the board
unscrambler. With LEDs and phototransistors mounted on the same
board, the diffuse scanner can be mounted above or below the transfer
deck depending upon ambient light conditions. The units come in
8-inch increments from 8" to 64" long. Discreet I/O sent to a
remote I/O block. I/O can be combined in groups according to individual
requirements. For a PowerPoint presentation (note 7 MB file) of an

An installation feeding a high-speed
planer was so successful it resulted in a 24-day payback at a savings of
over $180,000 per year! To view a video of this installation

ScanMeg has a few systems that can provide board length measurement
on a transfer deck. This is often important in planer mills where
there is no trimmer optimizer to provide this information.
Typically mechanical wands were used but these were often unreliable and
require maintenance.
The Type L Light-curtain Scanner is one method to provide
board length. The advantage of this unit is that it spans the
whole distance across the deck and has no problem with badly bowed
boards (although bowed boards are usually not a problem after drying).
This scanner has a 1/8-inch (3mm) length resolution. It comes in
2-foot sections that plug into connecting bridges to provide a daisy
chain from one sensor to the next. Scanning frequency is 1000
scans/sec. For Specification Sheet see: o More>>

The Type SE Long-range, Single Point Laser Scanner is another method
to determine board's length on a transfer deck. The scanner is
located on the far clear lumber line and picks up the far end of the
board as it passes the laser. Resolution is 0.100" (2mm) at 14
feet. The backset is 4-inches (100mm). In some cases, with
bowed lumber, as second unit is ganged together with the first to
provide adequate coverage. The advantage of this unit is that it
is not influenced by chainways. This has become a very popular
scanner for this purpose as it is simple to install and is very
accurate. For Specification Sheet see:

Only the SE scanner is required as long as there is an established near
lumber line. If not then a BBS48 Single-Point Laser will be
required. Plugging both laser scanners into a DIFF module will
provide the lumber length in inches or mm as the math will be done in the
on-board CPU. For a PowerPoint presentation see:
