The ProGrader is a complete optimization system for automated lumber grading. It is positioned just after the planer and allows replacing a part or all of the positions of the traditional graders. This equipment is reliable, constant and fast, allowing many of our clients to benefit from a return on investment in less than a year.

Tracheid Sensor Double Laser - TBS-2
  • New knot identification technology based on the detection of the wood fiber orientation
  • New TBS-2 sensor uses a dual laser technology to maximize tracheid data collection for high accuracy knot detection
  • The first laser emits a series of dots which are spaced at ¼"
  • The second laser emits a solid line spaced at ½" from the dotted line
  • The first laser line provides information on the direction of the fiber
  • The second laser line provides information on the tracheid effect in the fiber
  • By combining this data,  we are able to identify knots with a very high level of accuracy and with virtually no false detection
  • This new sensor is the first in our new series that can operate up to 4000 ft./min.
  • The operating speed of our sensor allows us to take readings at 1/8" (0.125") at 4000 ft./min.
  • We can also operate at a speed of 1/10" (0.100") at 3000 ft./min.
2D / Vision Sensors
  • Width resolution: 0.012” (0.31 mm)
  • Length resolution: 0.025” (0.63 mm)
  • Tri-linear CCD technology (100% color resolution)
  • Line rate: 24,000 images / second
  • High power white LED lighting (100,000 hours life expectancy)
  • Color calibrated at the factory
  • Low maintenance
  • Low white balance calibration cycle
  • Same technology as our previous version, using the same micro valves for the print nozzles
  • Each triple-nozzle high-speed head, prints 3 identical codes to ensure accurate reading at the UV code reader
  • Same shape and dimensions as our previous version so no modification required for installation
  • Assembled in 2 parts making it easier and faster to replace:
    • fixed part connected to the printer
    • mobile part can be removed and sent to Autolog for service

New UV quick connect printer head

Board Tracking System
  • The Autolog ProGSP prints a unique ID number on every single board
  • Up to 150,000 boards can be stored in a Microsoft SQL Server database which makes possible and easy to retrieve all optimizer data, board pictures, analysis and more
  • Powerful tool when inspecting boards for QC purposes
Remote Interface Tablet Option
  • The remote wireless interface tablet lets your QC personnel take control of the optimizer interface and allows getting direct info on each of the boards
  • A Wi-Fi network and a protective case are included
  • Autolog supplies an interface tablet (iPad or others)
Check Grader for QC Analysis (Option)
  • The Check Grader Dynamic Grading Zone system consists of an industrial light bar made of powerful LEDs at 1” spacing which light up and travel with the boards for the length of the bar
  • The light bar replaces the optimizer spraying system by showing the optimizer grade solution to the Check Grader by means of different colors; each color representing a specific grade. The light bar can be installed on a flat chain thus allowing more time to change a grading decision.
  • The LEDs are connected 2 by 2 to increase system reliability
  • The Check Grader Dynamic Grading Zone system can display near and/or far end info
Bow Detection System (Option)

To measure the extreme bow of a board with better accuracy:

  • Industrial sensors
  • Industrial computer system
  • Measures surface deviation (bow) of a board
  • Sends data to the optimizer
  • Reading every 0.250" along the length
  • Static precision of 0.150"
  • Presently tested up to 180 lugs/min.

Under these conditions, a human grader is not as accurate as the machinery that never gets tired and works in fractions of a second. The Autolog tracheid system reads the actual pores of the wood and records up to 27,000 frames per second. For us, it combines to make the difference between a mill that will turn a profit or post a loss.
