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
The present invention relates to a kind of sectional area is the automatic gauge method of the timber measurement of rectangle.Can be accurate by the method, add up reliably, adjust, objectively reflect its volume.
Background technology
Along with the development of industries such as building, finishing and wood working, the lumber market has obtained development rapidly, just is being subjected to people's growing interest.At present, the goods that timber processing factory (timber floor factory, furniture factory etc.) advances all is that the sectional area of process preliminary working is the timber of rectangle, and traditional measuring method mainly is by manual measurement, and survey instrument is a ruler.The personnel that manual measurement needs on the one hand are many, and labour intensity is big, efficient is low, and the flexibility of the sum of errors timber of ruler self itself all can be brought error, on the other hand, because whole measuring process all is the people for carrying out, measuring speed is slow, and human factor can be brought certain error.Therefore, finding one, accurately, reliably, objectively to measure sectional area be that the method for rectangular timber becomes key.
Summary of the invention
The purpose of this invention is to provide a kind of sectional area is the automatic gauge method of the timber measurement of rectangle, and the sectional area that travels at the uniform speed on conveyer with sensor measurement, the measurement of computing machine display technique is the timber of rectangle.The utilization of this method can reduce manual measurement intensity, improves the accuracy of measuring, objectivity.
The technical scheme that the present invention is taked for achieving the above object is: this sectional area is that the automatic gauge method of rectangular timber volume may further comprise the steps (key step comprises :): sectional area is that the timber of rectangle at the uniform velocity passes through conveyer, when entering the optoelectronic switch detection zone, the transmitter and the light between the receiver of optoelectronic switch will be blocked, begin to produce switching signal, leave detection zone until timber, switching signal stops to produce, how many computational length Y by the counter switch signal, the baffle plate that then will promote the place ahead produces an angle [alpha] in the horizontal direction, after this angle is amplified by reductor, be input to absolute type encoder angular displacement is converted to displacement of the lines, calculate its width X, another baffle plate that then promotes the place ahead again produces an angle beta at vertical direction, same this angle is amplified by reductor, be input to absolute type encoder angular displacement is converted to displacement of the lines, calculate its height Z, to grow by conversion equipment, wide, high signal passes to host computer, and V=X*Y*Z calculates by cubature formula, show its volume.Promptly when sectional area be that the timber 4 of rectangle is when sending into measuring apparatus by conveyer, be vertically mounted on the optoelectronic switch 5 of conveyer the right and left, 6 measure its length X, during by horizontal direction baffle plate 2, to produce an angle [alpha], when promoting vertical direction baffle plate 3, to produce an angle beta, the angle that horizontal direction baffle plate 2 and vertical direction baffle plate 3 produce is sent to reductor and carries out the signal amplification, then signal conveys is arrived absolute type encoder, absolute type encoder is converted to displacement of the lines to angular displacement, again with width, altitude signal passes to host computer and handles by cubature formula V=X*Y*Z, shows its volume.
Beneficial effect of the present invention: it is simple that this invention has metering method, is easy to advantages such as realization.The most basic purpose is to realize that sectional area is the automatic gauge of rectangular timber volume, not only save human and material resources, also improved the speed of measuring, precision, guaranteed that sectional area is the objectivity of rectangular timber metering, more can embody the fairness of timber supplier and processing side transaction.
Below in conjunction with accompanying drawing this automatic gauge method is further specified.
Description of drawings:
Fig. 1 is that sectional area is the structure principle chart of the timber measurement of rectangle;
Fig. 2 is that optoelectronic switch measurement sectional area is the synoptic diagram of the timber length of rectangle;
Fig. 3 is that sectional area is the width and the altitude signal processing connection diagram of the timber of rectangle.
Fig. 4 be pair cross-section long-pending be the width of timber of rectangle and the connection diagram that altitude signal is handled.
Embodiment:
Among Fig. 1, conveyer 1 is installed in vertical direction 2 and horizontal vertical direction 3 baffle plates, and vertical fixing is installed in the optoelectronic switch 5 and 6 of conveyer 1 the right and left, and optoelectronic switch supports by support 7.The baffle plate of vertical direction 2 and horizontal direction 3 need be installed on the rotation axis.
Among Fig. 2, Fig. 3, the transmitter 8 of conveyer 1, optoelectronic switch, receiver 9.Block transmitting of optoelectronic switch for fear of dust or other foreign material, effectively prevent the false triggering optoelectronic switch, with optoelectronic switch 8,9 closely vertical fixing be installed in vertical direction, support by support 7, the length signals that optoelectronic switch is measured compares by comparer, removes irrational measurement data, and rational data are averaged, obtain its length, reduce measuring error.
When sectional area is the timber 4 of the rectangle angle [alpha] that promotes baffle plates 2,3 and produce, β, because of the angle of its generation less relatively, the signal that is delivered directly to absolute type encoder can be very weak, can bring error to measurement,, will carry out signal to angle [alpha], β and amplify in order to reduce error, among Fig. 4, comprise baffle plate rotation axis 10, reductor 11, reductor input/ output port 12 and 13, absolute type encoder 14, the input/ output port 15 and 16 of absolute type encoder.When rotation axis 10 produces angle [alpha], being input to reductor 11 by chromacoder amplifies, reductor afterwards is transported to absolute type encoder 14 by output port 13 through corresponding amplifications angular displacement is converted to displacement of the lines, and the output port 16 by absolute type encoder is sent to host computer and calculates, shows again.
