Abstract
A method of sawing logs by using the combination of a plurality of square timber board specifications relates to a method of processing logs and sawn timber, and improving processing output rate of logs. The method solves the problems of low processing output rate of logs and swan timber, large waste of log resources. The processing method comprises the following steps: centrally summarizing and analyzing specification requirements of a plurality of customers, according to the required square timber board specifications of the customers; combining the analyzed content and formulating a plurality of sawing and processing plans; and drawing and formulating an operation table for a saw operator, namely comprehensive processing table of logs, according to the formulated sawing plans; sawing and processing in specified sawing sequence by the saw operator, according to the sawing position and the sawing size of each saw of each log of each diameter level in the operation table; and stacking and decking sawed square timber boards of different specifications according to specification classification. The method greatly improves the processing output rate of logs, increases output rate by 25%-35% per m<3> log and saves logs by 0.23m<3>-0.35m<3>.
Description
Technical field
The present invention relates to a kind of method of saw cutting log.
Background technology
Traditional log sawing processing, a log is only processed a kind of plate square bar of specification.Thickness by plate square bar to be processed during sawing is cut into lath, again lath is cut into required plate square bar by width.The lath and the super wide lath of not enough width are cut into the additional edge strip of plate square bar, all do waste material and abandon.Therefore, with traditional log saw cutting processing method, the processing volume recovery can only reach 30%～50%.
Summary of the invention
There is the problem that volume recovery is not high, the log resource wastage is big in the present invention in order to solve existing log sawing processing, and then a kind of method for saw cutting log that utilizes the combination of plurality of plate square bar specification is provided.
Technical scheme of the present invention: utilize the method for saw cutting log of plurality of plate square bar specification combination to realize: step 1, according to the required specifications of plate squares of client, with the concentrated Macro or mass analysis of how tame client's specification requirement according to following steps; Step 2, the content that step 1 is analyzed make up and work out multiple sawing processing scheme; Step 3, the sawing scheme that step 2 is formulated, the also establishment log comprehensive process table of drawing; Step 4, the strictness of sawing hand are set the sawing position and the sawing size of each saw by requirements of operation form to each root log of each footpath level, and sawing is in accordance with regulations carried out sawing in proper order and processed; Step 5, the different size plate square bar that sawing is shaped are placed by the specification classification.
The present invention has following beneficial effect: the inventive method has greatly improved log processing volume recovery.The plate square bar that utilizes the inventive method sawing to become effectively utilizes log resource, every M
3Log can improve volume recovery 25%～35%, saves log 0.25M
3～0.35M
3With yearly productive capacity is a ten thousand stere (M
3) product calculating, annual can the saving cut down log resource 2500～3500M

The specific embodiment
The specific embodiment one: present embodiment is described utilizes the method for saw cutting log of plurality of plate square bar specification combination to realize according to following steps: step 1, according to the required specifications of plate squares of client, with the concentrated Macro or mass analysis of how tame client's specification requirement; Step 2, the content that step 1 is analyzed make up and work out multiple sawing processing scheme; Step 3, the sawing scheme that step 2 is formulated, the also establishment log comprehensive process table (sawing hand operated form) of drawing; Step 4, the strictness of sawing hand are set the sawing position and the sawing size of each saw by requirements of operation form to each root log of each footpath level, and sawing is in accordance with regulations carried out sawing in proper order and processed; Step 5, the different size plate square bar that sawing is shaped are placed by the specification classification.
The specific embodiment two: as Fig. 1 and table 1, present embodiment serves as the main example that is combined as in conjunction with processing plate square bar with the processing sleeper, is realized by the following step:
Step 1, according to sleeper and the required specifications of plate squares of client, Macro or mass analysis is concentrated in how tame client's specification requirement, the sleeper specification is: the sleeper 3 of 16cm * 22cm; 16cm * 24cm; Specifications of plate squares is: the plate side 4 of the plate side 2 of the plate side of 1.5cm * 10cm 6,1.6cm * 10cm, 1.8cm * 10cm, 2.0cm * 10cm, 3.0cm * 4.0cm, 3.8cm * 8.8cm, 4.0cm * 9.0cm;
Step 2, the content that step 1 is analyzed make up, and work out multiple sawing processing scheme;
Step 3, the sawing scheme that step 2 is formulated are drawn (referring to Fig. 1) and establishment sawing hand operated form, title " log comprehensive process table " (referring to table 1);
The sawing position and the sawing size of each saw set in step 4, the strictness of sawing hand to each root log of each footpath level by the requirement of operation form, sawing processing is engaged in sawing in accordance with regulations in proper order, processing is the log of ￠ 24.5cm length 3m through level: the first step, log is fixed in the sawing platform after, edge 0.4cm saws down apart from peeling, sawing first saw; Sawing platform feeding 2.2cm is saw down, sawing second saw; Per two steps, with log along axial line Rotate 180 degree, the plane that goes out with sawing leans against on the sawing platform locating surface and after fixing, anomaly face (locating surface) 21.9cm is saw down, sawing the 3rd saw; Sawing platform feeding 1.8cm is saw down, sawing the 4th saw; Sawing platform feeding 4.3cm is saw down, sawing the 5th saw; The 3rd step, log revolved along axial line turn 90 degrees, the plane that goes out with sawing leans against on the sawing platform table top and after fixing, apart from peeling edge 0.9cm saw down, sawing the 6th saw; The 4th step, with log again along axial line Rotate 180 degree, the plane that goes out with sawing leans against on sawing platform table top and the locating surface and after fixing, 1, anomaly face (locating surface) 23.6cm saw down, sawing the 7th saw; 2, sawing platform feeding 1.8cm saws down, sawing the 8th saw; The 5th step, with second saw, the 4th saw, the 5th saw, the 8th plate that get off of saw sawing by corresponding specification sawing width, both finished the sawing processing of whole log.The volume of this root log is 0.161M
3, the plate square bar that sawing is finished is: 0.1056M of sleeper 16cm * 22cm
3Two 0.006M of plate side 1.5cm * 10cm
30.006M of plate side 2.0cm * 10cm
3Two 0.0216M of plate side 4cm * 9cm
3Add up to 0.1392M
3, volume recovery is 84.46%.The log of other each footpath utmost point is by the footpath utmost point corresponding in " log comprehensive process table ", with above-mentioned identical method processing;
Step 5, the different size plate square bar that sawing is shaped are piled up by the specification classification and to be banked up.
