KR101665913B1 - Sable based the outside of the sanctions to improve yield solid wood timber cutting position automatically turn - Google Patents

Abstract

The present invention relates to automatic setting of a cutting position of a first skin based on the outside of solid wood timber to improve a yield of the solid wood timber. The purpose of the present invention is to automatically set the cutting position of the first skin to improve the yield of the solid wood timber when sawing logged solid wood timber, which has a standard length, has respective diameters, and is not classified. In an attachment conveyor, an upper loading body of a common sawing machine, a sensor and an encoder are installed at both points at which top and bottom faceplates are positioned to detect an entrance time and a passage time, detect a pulse to the encoder in a rotary section until the detection of the sensor to separate the top and bottom faceplates and transmit the separated information to a computer. The computer computes a cutting point of a first skin of solid wood timber, based on the outside of the solid wood timber on the top and bottom faceplates, not based on the center of the solid wood timber. The computer detects an optimal cutting point of the first skin of the solid wood timber, and sends the detected optimal cutting point to a hydraulic digital automatic cart. A head block of the hydraulic digital automatic cart entirely or partially operates its front and rear positions depending on an execution instruction to detect the optimal cutting point of the first skin of the solid wood timber, thereby being automatically set such that the sawing machine can saw the solid wood timber. The present invention can improve a yield of solid wood timber by using the sawing machine being in use and complementing the function thereof, and can enable a worker, not a skilled worker, to efficiently perform sawing work.

Description

Technical Field [0001] The present invention relates to a method for automatically setting a cutting position of a hippocampus based on the outside of a wood for improving the yield of a wood material,

The present invention relates to a method of automatically setting a cutting position of a cutting point based on the outside of a log for improving the yield of a log, and more particularly, to a method of automatically setting a cutting position of a log, And a method of automatically setting a hippocampal cutting position on the basis of the outside of the log.

Trees cut from the mountains are sorted by use and length, and the materials selected as lumber are transferred to the sawmill and the logs of each length are transferred to a predetermined standard.

In this case, the wood should be processed considering the diameter of the original (thick part) and the end part (thin part). Especially, the first position of the cutting of the wood is the sanction of determining the yield of the wood. And the amount of discarded waste wood will vary.

In addition, yields vary depending on width and thickness, but considering the amount of sawdust to be produced when the material is used, 50 to 60% of the wood is commodity and the remainder is waste wood.

Therefore, when the output of the product is higher than that of the pulp, the cost of the lumber is reduced. Therefore, many studies and efforts are being made to improve the yield.

In the case of domestic, the method of catching the cutting position (first position) to cut the raw material is determined by the visual judgment of the skilled worker according to the skill and experience, so that the cutting yield is low, The worker is aged and the number of skillful workers is reduced, and the difficulty of the raw material is accompanied by many difficulties.

In addition, there is known a high-priced material equipment in which a CCD camera (Charge-Coupled Device Camera) capable of detecting a raw wood is installed in the process of setting the first material position. However, since there are many small- It is less economical than sanctions and is not spreading.

In the 1970s, advanced countries that produced many kinds of wood such as USA, Canada, Chile, and Russia used BDF (Best Opening Face) Optild modeled as a process (Rip-first Process) was applied. In the 1990s, GR-1ST model development (Hoff) was applied.

In the above, there is a drawback that the equipment price is high in the method of inspecting and calculating by the application of the CCD camera which is known to have a high optimum yield, and the set program has a drawback that the equipment cost is low in the domestic wood material, .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will now be described in detail with reference to the drawings.

1 and 2, when a log 100 is loaded on a conveyor 1 as a log stack, the log 100 is conveyed to the agitant conveyor 2 as a stand-up carriage and the log 100 is placed on the chain saw 2a 1, 3 (a), 3 (b), and 3 (c), in a conventional log maker 4, which is moved to a hydraulic digital automatic truck 3 and an operator fixes the log 100 with a bracket, And the diameter of the grooves and the corners of the log 100 as shown in FIG. 4 and calculates the information about the cutting position 3b of the wood material at the optimum yield based on the outside, and sends it to the hydraulic digital automatic truck 3 The sensor 10 and the encoder 11 are installed on both sides of the above-mentioned abdomen conveyor 2 so as to adjust the position 3b of the cutting point of the pellet, (Bold point) and a passing point (passing point) are detected, and the encoder 11 until detection of the sensor 10 is detected, The computer 20 receives the information and detects the pulsing of the rotation section and transmits the detected information to the computer 20. The computer 20 receives the information and determines the optimum cutting position 3b And an execution command is sent to the hydraulic automatic teller 3 and the head block 3a of the hydraulic automatic automatic teller 3 adjusts the positions before and after the execution command in whole or in part in accordance with the execution command, The automatic bogie 3 repeats left and right traveling on the rail with reference to the top of the sawing machine 4 that is rotating in advance, I will perform the work

The computer 20 for calculating the information detected by the sensor 10 and the encoder 11 does not refer to the center of the log 100 but refers to the log 100 on the basis of the outside of the log 100 The cutting position 3b of the cutting edge 3b is found.

In addition, according to the present invention, the log 100 loaded on the hydraulic digital automatic truck 3 is automatically executed at the optimal hippocampal cutting position in order to improve the yield in accordance with the information transmitted to the hydraulic automatic lorry 3, It is possible to easily and precisely carry out the sanitizing operation and to easily acquire the above-mentioned sanitary technology.

The present invention can calculate the diameter of the circle and the tail of the log 100, mathematically calculates and combines the sizes of the logs, finds the optimum yield, and performs the retention.
In addition, the hydraulic digital automatic bogie in use can be used without replacement.

For example, if a plate material having a thickness of 40 mm and a width of 75 mm is produced by using a log 100 having a diameter of 200 mm and a diameter of a circle of a circle of 280 mm, the optimal outer reference square cut position based on the outside of the log is calculated by the computer 20 The information is located 272.7mm from the top (280mm in the circumference - 200mm in the circumference = 80mm in the deviation) and 27mm in the case of the barrel diameter of 80mm. (272.7mm - 80mm = 192.7mm) and stops at 192.7mm from the top, it becomes the optimum cutting position of the outside of the log.

1. The first position where the cutting saw cuts into the wood during the cutting process has an absolute effect on the yield
2. Disadvantages in adopting the first position of the optimum cutting top relative to the center of the wood
- Limit the diameter of the logs because it is necessary to classify the optimal diameter of the logs for production products (equivalent to mass production of the same product)
3. Advantages of adopting the first position of the optimum cutting top
- Suitable for various production products
- Optimal material yield can be obtained irrespective of the diameter of the sawing logs
(Corresponding to large-volume mass production)
