Timber Measuring System
for Band Saws

The application is designed to measure the number of pieces and cubature of logs during log processing on a band saw.

The measuring device is installed on a stationary part of the machine and the log is measured during cutting. The operator selects the tree species and the quality of the log before the processing is completed. Each measured piece is registered in a database.

Application Properties

  • measurement of logs during cutting
  • records of logs and cut-outs on delivery notes
  • automatic data transfer to the office

Measuring Properties

Diameter is measured in vertical axes in the full length of the log at least every 5 cm. Length is measured by the movement of the carriage.

  • vertical axis with an accuracy of ±1,0 cm
  • length with an accuracy of 2 %

Control Program Properties

  • support for fully automatic operation without operator intervention
  • touch screen control support
  • calculation of wood wolume, curvature, convergence and subtraction of the bark, etc. according to Czech standards
  • parameters recorded for each log
    • processing time, operator name
    • length, center diameter, pin diameter, quality etc.
    • curvature, convergence etc.
  • registration of each log in the database
  • remote data browsing

Use case

The measuring device is installed on a stationary part of the band saw and measures the log, which is caught on the carriage.

The measurement does not affect the cutting process. The production manager can browse the database of processed logs online to know the exact course of processing. The manager can monitor employee and band saw productivity.
