Configuration and Features
ScanHeads: we use proven scanning technology by JoeScan Inc.:
-With the binocular JS-50 WX-100 as the standard model, chain flights don’t obscure the log (on 3D and 4D)
-For large log diameters, JS-50 MX can be substituted
-Budget systems with JS-50 WSC (only 1D and 2D)
Cabling: all scanners are PoE powered – a single cable per head provides power and data.
JoeScan ScanSync Module: synchronizes all devices for high scanning speed (up to 2 kHz) and crosstalk prevention
Standard Scan Frame: stable, space-efficient frame that can be installed over your chain without modification. We will work with you to determine the optimal location.
Standard Cabinet: all electronics in one place, dust-proof. You just supply power.
Gigabit PoE Switch: we use an industrial grade PoE switch to connect scanners, ScanSync and processing computer.
Encoder: Differential incremental quadrature encoder, to be mounted on your chain. We will work with you to find the optimal location, or re-use existing, compatible encoders.
Processing computer set (PC, monitor, keyboard and mouse)
Alignment Fixture: check your scan accuracy in minutes.
Software
ExNovo LogScanner Base Version:
Full 3D log modeling with up to 1 mm profile density
Measures basic set of log properties: Length, Top and Bottom End Diameters, Conicity/Taper, Sweep/Curvature, Min/Max Diameters, Envelope, Volume, Root Flare
Robust filtering algorithms for debris, hanging bark and other obstructions
Additional Modules:
-Fitter: create optimized cylinder fits
-Sorter: sorting line driver via PLC
-Database: keep all scanned logs for accounting and analysis
-Peeler: maximize recovery with optimized chucking points
-Custom: get access to the API and write your own modules

Environment, Speed and Accuracy
LogScanner is designed for the harsh conditions in the sawmill.
Operating temperature: -20°C to +50°C.
Light shielding:
-Indoors: no shielding necessary. You may need to block direct view of light sources.
-Outdoors: only with tunnel or other light-blocking structure
Laser Class: 3R, pulsed
Accuracy (depending on configuration):
-Length: +/- 10 mm or better, depending on chain speed
-Diameters: +/- 1 mm or better
