ABSTRACT:
An area measuring attachment for a linear conveyor is disclosed. The device is particularly adapted for area measurement of long, narrow objects having an irregular height and angular orientation, for example lumber, and particularly rough-cut lumber. The device includes an array of independently suspended, generally vertically oriented, freely rotating wheels. The wheels are equally spaced in a direction transverse to the direction of travel of the conveyor. Frictional contact between the wheels and the objects passing on the conveyor define the width and length of the objects. The wheels are pivotable about a first axis, generally transverse to the direction of travel of the conveyor, for accommodating objects having a warp or an irregular height. The wheels are also pivotable about a second axis, generally parallel to the direction of travel of the conveyor, for accommodating objects having irregular angular orientations. The wheels, in conjunction with their suspension apparatus, are adapted to produce electrical pulses representative of wheel rotation, and digital electronics are included for counting such pulses and generating an output in terms representative of the area or board footage of the objects passing on the conveyor.
