Abstract

PURPOSE:To classify and treat the sawed material by arranging a plurality of elevating/lowering tables for positioning so as to be orthogonally crossed to a carrier belt, forming a material feeding path, individually or simultaneously raising the elevating/lowering tables in accordance with the size of width of lumber, classifying and carrying lumber. CONSTITUTION:Sawed lumber 17 is carried on the elevating/lowering tables 4 5 by a carrier belt 2 and a width narrowing belt 3. When sawed lumber 17 is brought into contact with a detector 6 provided on the table 4, the belt 2 is stopped and the table 4 is raised to the prescribed position. When dimension of width is large, sawed lumber is tilted from the table 4 by gravity and separated from the detector 6 anal the table 4 is lowered. Sawed lumber is recarried by the belt 2 and raised to the prescribed position by simultaneously raising the tables 4, 5. Picture treatment is performed by a measuring camera provided in the side face and carrier position and loading height are decided by a controller. A loading table 16 is moved to the position of a loading arrangement on the basis thereof. Sawed lumber 17 held by the piercing jig 14 of a horizontally moving device 8 is moved to the loading position and loaded on a table 16.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood sorting and loading apparatus.

[0002]

2. Description of the Related Art A standard material obtained by sawing a log of raw wood with a sawing machine has a high water content, for example, a pine material having a size of 120 mm × 3.
Since the size is 00 mm × 4000 mm and the weight is as heavy as 110 kg, a group of two people is currently sorting and conveying by visual measurement to carry out the loading process. As an improvement of this, for example, Japanese Patent Publication No. 59-30521 and Japanese Patent Publication No. 3-16
However, these are merely sorting devices for the product material and the residual material sawn by a sawmill, and have different cutting dimensions depending on the highly automated sawmill. It is impossible to handle sorting work in which sawdust is discharged at high speed. Further, as a loading processing device, there is Japanese Patent Publication No. 2-13602, but this is only suitable for stacking veneer plates having the same standard size, and 4 to 5 different sawing materials depending on the size of the lumber. It was impossible to measure, sort, and load each of the cross-section dimensions.

[0003]

[Problems to be Solved by the Invention] In order to save labor in a sawmill, automatically measure the cross-sectional dimensions of each sawmill of four to five different sizes that are simultaneously delivered by a sawmill. Then, there has been a demand for a wood assortment loading processing device capable of sorting and loading according to standard dimensions.

[0004]

In order to achieve the above object, the wood sorting and loading apparatus of the present invention has a plurality of positioning lifting tables arranged orthogonal to the wood conveying belt driven by the motor. The sawing material that forms the material feeding path and performs the sorting and loading process contacts the wood detector to stop the conveyor belt, and raises the sawing material to a predetermined position on the first lifting table. When the width is large, the sawing material tilts due to the weight of the sawing material and moves away from the wood detector, and the first lifting table is automatically lowered. The sawing material is again conveyed by the conveyor belt and contacts the wood detector. Then, the first elevating table and the second elevating table are simultaneously raised to predetermined positions, the width dimension and the thickness dimension of the sawing material are measured, the process is controlled, and the sawing material is standardized by the horizontal moving device. By size A mechanism for loading processing to the loading table is transported to the designated stacking table is made is constituted by truck to take out from the stacking table.

[0005]

The apparatus of the present invention constructed as described above is provided with a positioning elevating table orthogonal to the sawing material conveying belt and the width-shifting belt which are driven by two sets of electric motors for the right and left sides of the feeding path. In the case where the sawing material is larger than the first lifting table, the conveyor belt is stopped by the wood detectors provided on the two sets of positioning lifting tables, and the sawing material is simultaneously lifted to the predetermined measurement position on the first lifting table. Is tilted due to the unbalance of wood weight, and the wood is separated from the wood detector, the two sets of lifting tables are lowered, the sawing material is moved again by the wood transport belt, and stopped by the wood detector.
This time, two sets of the first lifting table and the second lifting table are simultaneously raised to the predetermined measurement position, the width and thickness dimensions of the wood are input by the wood measuring camera, and the image-processed output signal is the main signal of the control panel. By the process control by the controller and the sorting signal for each standard dimension, the sawdust material is horizontally moved to the predetermined loading position by the horizontal movement device and conveyed.
At the same time, it is possible to perform the loading process of sawing material by operating the predetermined loading and unloading table for each standard size by the loading signal and moving it up and down, and also to extend and contract the vertical support arm of the horizontal moving device. You can also control the amount of vertical movement.

[0007]

[Effect of the Invention] Even in the current rationalized new lumber mill, no rationalization has been made regarding the selection and loading processing of sawdust, and two men's work eyes form one group. As an example, a pine wood material having a high water content and a weight of 90 kg was required to be loaded at a specified number by visual judgment and manual conveyance at a work speed of 5 pieces per minute. Since it has been difficult to automate the wood sorting and loading process in the sawmill, it was caused by the worker being forced to engage in dangerous work and work under adverse conditions such as high noise and saw dust. It was possible to prevent various occupational diseases such as occupational accidents and low back pain and arm and elbow pain, and workers were released from severe and heavy labor, so workers could be established and rationalization of the sawmill was completed. In addition, we can contribute to labor welfare.
