Method for automatically counting volume of wood with rectangular sectional area

Abstract

The invention relates to a method for automatically counting the volume of a wood with a rectangular sectional area. The wood with the rectangular sectional area moves forward at a constant speed on a conveying device; photoelectric switches fixed on the left and the right of the conveying device are used for measuring the length of the wood with the rectangular sectional area; the wood with the rectangular sectional area pushes baffles which are arranged in the horizontal direction and the vertical direction so as to produce angles alpha and beta in the horizontal direction and the vertical direction respectively; the angles produced by the baffles are amplified by a speed reducer in a signal way and transmitted to an absolute encoder; the absolute encoder transforms an angular displacement into a linear displacement, and transmits a width signal and a height signal to an upper computer; and the width signal and the height signal are processed by the upper computer according to a volume formula V=X*Y*Z so as to display the volume of the wood. By adoption of the method for automatically counting the volume of the wood with the rectangular sectional area, the counting method is simple, finished automatically, and high in speed and precision; moreover , labors and resources are saved, the speed and the precision of measurement are increased, the accuracy and the objectivity of automatically counting the volume of the wood with the rectangular sectional area are guaranteed, and the transaction fairness between a wood supplier and a manufacturer is embodied. By application of the method, the manual measurement intensity is reduced, and the accuracy and the objectivity of measurement can be improved.

Description

Technical field [0001] The invention relates to a method for automatically measuring the volume of wood whose cross-sectional area is rectangular. Through this method, accurate and reliable statistics and accounting can be used to objectively reflect its volume. Background technique [0002] With the development of construction, decoration and wood processing industries, the wood market has developed rapidly and is receiving increasing attention. At present, the goods imported by wood processing plants (wood floor manufacturing plants, furniture manufacturing plants, etc.) are all pre-processed wood with a rectangular cross-sectional area. The traditional measurement method is mainly through manual measurement, and the measuring tool is a ruler. On the one hand, manual measurement requires a lot of personnel, labor intensity, and low efficiency. The error of the ruler itself and the curvature of the wood itself will bring errors. On the other hand, because the entire measurement...
