US 4,231,460 A · System for transferring wane-edged boards

Abstract

System of transferring wane-edged boards through a control station for edging to detect the wane consistent and possibly other characteristics of the board automatically. The board is first aligned automatically by transporting each board separately and sequentially against a first group of fixed transversal stops to provide the same sawing line for each sequentially fed board; then each is moved sequentially from the transversal stops to and through a control station where the wane consistent and other features may be detected. The information is recorded in a data processing unit memory, and then the board is transferred to an edging station and aligned against a second group of transversely positioned adjustable stops. The movable stops are optimized on the basis of information supplied by the data processing unit based on quantities measured at the control station and other information so that each of the boards is transferred to the same sawing line. The aligned board is then charged into an edging machine along a sawing line which is predetermined at the control station.

Dependent claims

A system for continuously transferring wane-edged boards through a control station prior to edging to measure the wane edge for a controlled positioning of the board prior to the continuous sequential edging thereof in an edge saw mechanism, comprising:

first conveyor means to continuously align while supplying a plurality of boards sequentially both longitudinally and transversely prior to feeding of the board through the control station to provide an output indicative of the orientation of each board,
data processing means coupled with said control station and responsive to information output thereof to store information characteristic of the wane consistent of the boards and the orientation thereof, and
second conveyor means adapted separately to receive the boards from the control station to align the boards in sequence transversely and longitudinally for continously feeding thereof to said edge saw mechanism, said second conveyor means including adjustable positioning means responsive to the output of said data processing means for controlling the optimum alignment of the boards prior to the feeding thereof to said edge saw mechanism.
