Conventionally, when cutting and separating defective parts of a veneer, it has been difficult to detect defective parts such as rotten parts and knots of the veneer using a normal detector. For this reason, workers visually identify the parts and break the parts by hand or partially break and separate the end of the veneer, making it detectable with normal detectors. This required time and complexity.

る。 In addition, a veneer processing machine that marks defective parts of veneer with a marker that can be detected by a detector and treats them has been proposed, such as the device described in Japanese Patent Application Laid-Open No. 144862/1983, but this has not been put into practical use. The reality is that it has not been done.

In order to solve these problems, the present invention includes a conveyor that conveys the veneer in a direction perpendicular to the fibers,
A veneer detector is provided with a thickness reduction device that moves up and down in response to an input signal from a switch on the conveyor conveyor, and detects a defective part of the veneer in a direction perpendicular to the conveyance direction on the downstream side of the thickness step reduction device in the conveyance direction. Furthermore, a cutting blade operated by a detection signal from the detector is provided on the downstream side of the veneer detector in the conveyance direction.

備えた単板処理機１０を配置する。 On the downstream side of the conveyor 3, there are a plurality of known veneer detectors 7 for detecting defective parts of the veneers at positions orthogonal to the conveyance direction, and a control device that issues an activation signal based on the detection signal of the veneer detector 7. A veneer processing machine 10 equipped with a mechanism 8 and a cutting blade 9 that reciprocates as shown by the arrow in response to the activation signal is arranged.

It is provided on the line so that the step loss portion 2' can be detected.

せられ行なわれる。 On the other hand, a thickness reduction device 4 is provided on the conveyor 3 to reduce the thickness of the veneer in the thickness direction at the end of the veneer 2 corresponding to defective parts such as rotten parts and knots. As shown in FIG. 2, the thickness reduction device 4 includes an air cylinder 12 equipped with a roll 13 that can move up and down and whose tip can be driven by the end of the veneer 2 on the conveyor 3. . The air cylinder 12 can be moved up and down using the button switch 1.
An activation signal is issued from the control mechanism 8 in response to a signal when 1 is pressed, and the operation is performed.

る。 Next, the action will be explained in detail. Defects such as knots and rot in the veneer 2 excluding the front and rear ends of the veneer 2 transported by the conveyor 3 shown in FIGS. Then press switch 11. Thereupon, the cylinder 12 is moved downward, the roll 13 is pressed against the veneer 2, and the vicinity of the end of the veneer 2 corresponding to the defective part is compressed and deformed, resulting in a partially reduced step part 2 in the thickness direction.

と有効な単板２″とに切断分離されるのである。 When the veneer 2 is further conveyed and the reduced step portion 2' reaches the location of the veneer detector 7, the reduced step portion 2'
is detected by the corresponding single plate detector 7. Therefore, the detection signal of the veneer detector 7 is input to the control mechanism 8, and the cutting blade 9 is controlled by the output signal from the control mechanism 8.
moves back and forth, and the veneer 2 is cut and separated into a veneer with a reduced yield portion 2' and an effective veneer 2''.

で歩減りさせてもよいのである。 In the above embodiment, the yield was reduced by compressing the veneer 2 with the roll 13, but as shown in FIG. 3, a cutter or grindstone 15 capable of cutting and polishing is attached to the servo motor 14, and the illustration is omitted. However, the entire servo motor 14 may be moved up and down by an air cylinder, and the steps may be reduced by cutting off the corresponding portions.
