Work on sawing machine realizes in the following manner.When beginning, connects the work period personal computer, the starting optimization procedure, provide the sawn timber kind of needs and the criterion of a possible optimization sawing, such as: the maximum output capacity of the sawn timber of given kind, the maximum cost of the sawn timber that obtains, radially radially maximum cost or other standard of the sawn timber of sawing during the maximum output capacity of the sawn timber of sawing.
After this, on the screen of computer, select corresponding menu item, set up and being connected of controller 36, and program jump to listen mode, wait for and importing and the relevant data of being used by the sawing of saw cutting log 9 of optimization region parameter.After this, the operator of sawing machine might enter the optimization pattern.
Be loaded into saw blade 1 at log 9,2 before the planker 8 of log 9 relative moving mechanism, indicate the geometric parameter in optimization zone in the one or both ends of log 9 according to the true form of log 9, for example, the diameter of the inscribed circle on the top of input length of log 9 and log 9 when the shape on top and circumference are more or less the same (if), perhaps import the minor radius oval in the top inscribed circle of log 9 and the value of long radius (when the shape on top when oval), also input sign predetermined optimization zone at least borderline on the one or both ends that are located at log 9 on the end of log 9 at least.Under the situation of the top of log 9 inscribed circle, for example, import the last point of above-mentioned circumference.Under the situation of oval top inscribed circle, import an outermost point of its semiaxis line.
After log 9 loaded and is fixed on movable carriage 8, for example, the top that makes log was towards the operator, and the operator presses the corresponding button on the console:
-open the screen of parameter in the optimization zone on the top of input log 9;
-planker 8 that guiding subsequently has a log 9 almost contacts a plane to the top of log 9, this plane perpendicular to the moving direction of movable carriage 8 and advance by saw blade 1 or 2 the most approaching above-mentioned tops a bit;
-guide at least one saw blade subsequently, the for example vertical saw blade of arranging 1 is to the given top of descending most point and log 9 of saw blade 1 and be labeled in that (projection of going up point most in Fig. 4 inscribed circle week a) overlaps on the top of log 9, wherein the point that descends most of saw blade 1 is positioned on the plane, and this plane is perpendicular to the plane of saw blade 1 and the moving direction of movable carriage 8.
Its interior diameter value of pressing circumference of-terminal 38 input indications by console 37 on the top.
After this, terminal 38 is converted to the screen of the optimization region parameter of the butt of importing log 9, and the operator moves movable carriage 8 and almost contacts a plane to the butt of log 9, this plane perpendicular to the moving direction of movable carriage 8 and advance by saw blade 1 or 2 the most approaching above-mentioned butts a bit, guide a saw blade after this, the following point of for example vertical saw blade of arranging 1 and the given butt of log 9 also are labeled in the projection of going up point in the inscribed circle week of (Fig. 4 b) on the butt of log 9 and overlap, wherein the following point of saw blade 1 is positioned on the plane, and this plane is perpendicular to the plane of saw blade and the moving direction of movable carriage 8.Terminal by console 37 38 inputs subsequently it inscribed circles week diameter value the length value of log 9.
So, the sawing optimization zone of given log 9 and getting in touch of sawing machine coordinate have been realized.After this, controller 36 is transmitted the parameter in relevant optimization zone to personal computer, for given sawn timber kind and optimized criterion, personal computer carries out the calculating of sawing scheme by optimization procedure and selects the sawing scheme of the best of log 9 and the order of the step that the saw blade 1,2 corresponding with it moves along the reference axis of sawing machine.
In determining given optimization zone after the preferred plan of sawing, the image and the information board of the optimal scheme of output sawing on the monitor screen of personal computer, information board has the parameter in the given optimization zone of log 9, the size of saw blade, the criterion that best sawing is used, the quantity of part in the kind, the sum of part in the sawing optimal scheme, the sum of sawing step in the optimal scheme of sawing, the number of existing sawing step, the output capacity of final products, the percentage of sawdust and hair plates, whether the current regulations of sawing machine work exist to get in touch and hand over controller 36 to increase the relevant information of error in data and other, and terminal 38 automations of console 37 be converted to the optimization screen.In such cases, the order of subsequent working becomes as follows:
The operator presses corresponding button, accesses the optimal scheme according to the sawing of the log of selecting 9 on the terminal 38 of console 37, and saw blade 1,2 is along the movement value of sawing machine reference axis in existing sawing step.
The operator is according to the calculated value that moves on the rapid remainder of the previous step of log 9 at each saw blade of importing on the terminal 38 of console 37 subsequently, and consider by the particularity of log 9 shape of cross sections of sawing, there is the internal flaw of the log of opening 9 when warpage properties in the vertical or sawing, estimates the possibility of finishing next sawing step.
And if the saw blade 1 that faces, 2 mobile step allows to obtain the sawn timber of high-quality, then the operator presses " entering " button of terminal 38 on the console 37, affirmation is at this step inner circle saw blade 1,2 move, move along the automation that the movement value of the reference axis of sawing machine carries out each saw blade according to each saw blade on the terminal 38 that outputs to console 37 after this, and the operator controls the motion of movable carriage 8, according to the optimal scheme of selected sawing in the given optimization zone, realize the sawing of log 9 in the existing step of the order of the calculating of step.
If sawing scheme according to the best of selected log 9, the saw blade 1 that faces, 2 mobile step does not allow to obtain the sawn timber of the high-quality of given kind according to the order of the calculating of step, its reason is along the big scrambling of the length shape of cross section of log 9, the perhaps big warpage properties of log 9 in the vertical, or in the internal flaw of the log 9 that exists previous step to open during sawing in rapid, then the operator stops at the order of the calculating of the step in the given optimization zone, and take decision according to above-mentioned one or several reasons, perhaps proofread and correct the optimization zone and the sawing scheme of selecting new log 9 of sawing, perhaps in step subsequently, proofread and correct saw blade 1,2 movement value, and according to the saw blade 1 that is different from calculating, after 2 the mobile step, be back to order according to the calculating of the step of the optimal scheme of selected sawing.
So, the operator is according to by the characteristics of the reality of the log 9 of sawing, can use any combination of the sawing measure shown in above to realize the sawing completely of log 9.
In such cases, in the sawing process of log 9, on the screen of personal computer, mirror saw blade 1 continuously, the shape in remaining optimization zone after 2 the whole mobile and sawing in previous step is rapid, and in the hard disk of personal computer the quantity of log of the relevant sawing of record and the information of geometric parameter, the amount of the sawn timber that obtains, sawdust and plate, the information such as diagnosis of the control system of sawing machine downtime and sawing machine.
And the operator can press the corresponding combination of the keyboard on the terminal 38 of sawing machine console 37 at any time, obtains the quantity of saw cutting log when the work period begins, the quantity of the sawn timber that obtains at this moment, and in the information such as output capacity of present moment sawn timber.
