When it is carried in by the pawl 17 of the backboard lateral feed pawl conveyor 16 and reaches a predetermined position, the backboard lateral feed pawl conveyor 16 is temporarily stopped by a limiting switch (not shown), and at the same time as shown in FIG. The back plate thickness detecting plate 3 integrated with the rod 29 of the pressure cylinder 28 is operated by operating the electromagnetic circuit of the pressure cylinder 28 shown in FIG.
0 is lowered and at the left end of the back plate thickness detection plate 30, the back plate 23
The left end of the sloped sawn timber surface is first pressed to start leveling of the lumber sawed surface of the backboard 23, the backboard thickness detection plate 30 further descends, and at the position indicated by the dashed line of the stroke S1. , The sawn surface becomes horizontal, and the backboard thickness B is correctly detected.

図に示す底ゲート１１上に落下する。Even when the back plate is in the state of the back plate 22 shown in FIG. 3, that is, when the sawn surface is carried downward, if the back plate thickness detection plate 30 descends,
Since the back plate thickness detection plate 30 extends in parallel to the upper surface of the back plate receiving arm 4 in the direction of the fixed point of the rod 32, the back plate thickness B is correctly detected. At that time, if the claw 33 of the rod 32 comes into contact with the operating arm 37 of the limit switch 36 and the position of the limit switch 36 is set to S1, the limit switch operates and a pressure cylinder (not shown) is activated. Drive
The back plate receiving arm 4 is rotated counterclockwise so that the back plate 23 moves to the first position.
It falls on the bottom gate 11 shown in the figure.

る。When the thickness of the back plate 23 shown in FIG. 3 is larger than the first-stage sorting back plate thickness dimension B, and the back plate B + b is loaded,
Since the range of the back plate thickness detection plate 30 is S1-b, the limiting switch is not activated and the back plate receiving arm 4 does not rotate, and the back plate side feed claw conveyor 16 performs the next operation. Once started, the backboard 23 is conveyed to the top of the backboard receiving arm 6 and stopped.

Setting position S1 of the limit switch 36 of the plate thickness detection device
Is set to different operating values S2, S3, S4 for each sorting to detect the back plate thickness, and the corresponding back plate receiving arms 4, 6, 8,
Rotate any of 10 to drop the back plate on the bottom gate for sorting.
