ものではなかったのである。Detailed Description of the Invention (Object of the Invention) The present invention targets a veneer dried by a roller type veneer dryer and carried out in the direction of the fibers.
High moisture content veneers that tend to remain on the back side of the boards are reliably detected by inverting them, and before being fed to the side-seaming machine, workers sort and eliminate them to produce high-moisture content veneers as side-seamed products. The aim is to establish a new method for treating veneer in the plywood manufacturing process using a roller-type veneer dryer that prevents the contamination of veneer. There are methods and equipment for treating veneers in the plywood manufacturing process, and methods and equipment for selecting high moisture content #AFfi in the manufacturing of veneers for plywood (Japanese Patent Publication No. 55-45002). The veneer, which has been dried and is carried out in the fiber direction, is transferred in the direction orthogonal to the carrying direction at the front position of the carrying unit, and then it is turned upside down or downward and carried upside down. A method and apparatus for processing veneers in a plywood manufacturing process that centrally and automatically perform various operations such as cutting, stripping, and stacking the veneers, the method and device including inverting the veneers upward or downward. Conveying the veneer upside down is only significant because it makes efficient use of a narrow space, and therefore drying the veneer with this type of roller-type veneer dryer is carried out inside the oven. Due to the slow bending wind and cracks on the back side during cutting, the upper surface is difficult to dry, and a high moisture content portion remains on the lower surface, which is rough.In order to detect this, we carried out the reversal conveyance as described in @. It wasn't what I was used to.

式である。The latter is achieved by installing a moisture meter in a continuous drying device such as a net-type veneer dryer, and in conjunction with this, a rate meter, marking identification device, and speed control computer to obtain high moisture content of dried veneer. A method and apparatus for sorting moisture content veneers in the production of plywood veneers, which detects moisture content and distinguishes its color, the veneer being separated from the front and back without being turned over. In order to detect the residual moisture in the dry veneer, both sides turned it over and brought the moisture meter directly into contact with the residual moisture to ensure that this was detected. Therefore, in order to eliminate the drawbacks of these conventional methods, the present invention directly detects moisture from the top surface of the dry veneer that is carried out from the roller type veneer dryer after it is conveyed in reverse. In addition, this is a new processing method that allows workers to sort and eliminate veneers containing moisture that exceeds the control value by reversing the conveyance and returning it to its original state, and then painting an identification mark on the top surface.

の処理装置である。(Structure of the Invention) The first method of the present invention is to transport the veneer 2 dried by the roller type veneer dryer 1 and transported in the fiber direction at a position in front of the collection conveyor 5 constituting the transport section. While being transferred by the carry-in conveyor 4 in the direction perpendicular to the , the moisture is detected by the moisture meter 6 from the upper surface while being inverted upward by the reversing conveyor 5, and the detected moisture control value, for example, 15%. Once the detection signal exceeding the control value of The memory of the detection signal is synchronously reproduced in accordance with the conveyance speed, and an identification mark such as ink is applied to the upper surface using the spray 8 using the reproduced detection signal to contain moisture exceeding the control value. This is a method for processing veneers in a plywood manufacturing process that enables sorting and exclusion of veneers and continuously supplies them to a cross-cutting machine 9, and also the second device invention of the present invention (d-roller type veneer dryer 1). A carry-in conveyor 4 for transferring the veneers 2 perpendicular to the carry-out direction is provided at the front upper stage of the collection conveyor 6 constituting the carry-out section of A series of symmetrical reversing conveyors 5 are provided, which invert the veneer 2 horizontally and then revert it downward again at the conveying tip, and the horizontal part of the reversing conveyor 5 is in contact with the upper surface of the veneer 2. A moisture meter 6 is provided to detect the moisture content in the veneer dryer 1, and a cross-cutting machine 9 is installed at the front lower stage of the collection conveyor 6 that constitutes the unloading section of the veneer dryer 1. A spray 8 is provided on the discharge conveyor 10 to apply an identification mark to the upper surface of the veneer containing moisture exceeding the control value. This is a veneer processing device in a plywood manufacturing process, which is equipped with a memory device 7 that is activated in synchronization with the veneer conveyance speed when a detection signal from a moisture meter 6 exceeds a control value.

出コンベア10を経て横はぎ機9に受渡すものである。That is, as shown in the figure, one example of the present invention is that a load of dried veneer 2, which is sequentially delivered from unloaders 1a and 1b of a roller-type veneer dryer 1 onto a collection conveyor 6, is installed in the upper front stage thereof. The conveyor 4 is then delivered to the reversing conveyor 5 connected to the conveyance tip of the conveyor 4. The reversing conveyor 5 has a large radius of curvature (boo')-5a and 5b arranged symmetrically, and first turns the veneer 2 upside down on day IJ-5a, and then turns it upside down again to return to its original conveying state. It is then transferred to the horizontal stripping machine 9 via the carry-out conveyor 10.

除が可能になるように構成されているものである。Therefore, when the dry veneer 2 is first turned over, its upper and lower sides are turned over, and the lower side, where the high moisture content part tends to remain, becomes the L side, which comes into direct contact with the electrode i6a of the moisture meter 6, and the remaining moisture can be accurately measured. It is something that can be detected. On the other hand, if the detected residual moisture exceeds the control value for the veneer, the detection signal is stored in the storage device 7, for example, a magnetic memory synchronized with the conveyance speed of the reversing conveyor 5 and the unloading conveyor 10, a shift register, or a substitute for this. The veneer is sent to a storage device 7 consisting of a timer, etc., where it is temporarily stored, and then the veneer is reversed again on the reversing conveyor 5 1-'J-5b and returned to its original conveying state. The stored detection signal is reproduced and activated in the sprayer 8 equipped with the sprayer 8, and the sprayer 8 is configured to be able to sort and eliminate the upper surface of the veneer being conveyed directly below.

るものである。(Effects of the Invention) The present invention provides a roller type veneer dryer 1 as shown in E.
Once the dried veneer 2 is conveyed in reverse, its moisture is directly detected from the top surface, and after the reverse conveyance is returned to its original state, an identification mark is painted on the top surface to ensure that the moisture exceeds the control value. This is a new processing method that allows workers to sort and eliminate veneers that contain moisture, so unlike conventional methods, high moisture content areas remaining on the bottom surface of the veneer cannot be detected by simply detecting the top surface. It is possible to completely avoid unforeseen situations such as contamination in horizontally spliced products and causing punctures during plywood manufacturing, and the space can also be taken up by the reversing conveyor 5. By reversing it twice, it is possible to achieve excellent implementation effects such as being able to occupy only the minimum plane in front of the unloading section of the roller type veneer dryer 1.
