Theory About Design And Experimental Study Of Inspecting Machine Of Log's Shape

In our country, the wood manufacture industry inspect the shape and the volume of the log by manual work: through a worker's eyes to estimate log's outer shape and then label them before throwing into the process;people use the tape measure or the caliper to confirm a log's length and diameter of the section and look for it in the manual to obtain one log's volume. By accumulating all the volume of the log the number of the stock can be got. The work of inspecting the log by manual work is very heavy and hard.In this paper the theory of the eight point's inspection and the four point's compounding simulation is presented. So the system can quickly measure and get the log's external shape parameter accurately on-line with the automatic inspecting technique and computer stimulating technique. System adopt on-line quick measure and realize log's inspection by using computer. So the equipment can enhance work efficiency.In this paper, the eight point's inspection and the four point's compounding simulation is discussed detailedly. All of the equipment's capabilities are validated through contrasting between trim size and simulation.At the same time,drawing and design work are completed. The auther of this paper is in for the equipment's manufacture and debugging.Log inspection technique is recognized increasingly by lumbering. The equipment designed in this paper is a sort of experiment facility and also there are many question and juvenility. Things upwords will accelerate researching work for the future.
