In this case, the rotary blade used for unloading is continuously rotated while being pressed with a constant pressure while rotating, so depending on the surface condition of the veneers, they may get tangled and come out in twos or threes, or the veneers may slip out. When there are uneven undulations in the rotating material, there is a drawback that the part that first comes into contact with the rotating material blade is transported quickly, moves backwards, and is carried out to the next process in an unaligned state.

れるものである。In order to solve the above technical problems, this invention has the following points:
Predetermined value INL% of veneer! The power of the rotary blades to be applied is made independent of each other, and the rotary blades are crimped to the veneer with a predetermined pressure in a stationary state. Immediately after the first crimping, the predetermined pressure is instantly released and the highest fz layer is crimped. A gap is created between the laminated veneers to minimize the sliding resistance between the veneers, and the rotary blades do not rotate continuously but instead rotate for a limited period of time (within 1 revolution), allowing for unbalanced alignment during transport. Confirm the method 17. We have developed an unloading device using this method. There are various types of laminated veneers, including those that contain a lot of moisture and those that are dry, and those that contain a lot of moisture are pressed. If it is pressed, it becomes sticky and tends to stick together, and if it is dry, the surface becomes rough and fluffy, and when it is pressed, the sliding resistance is large and it tends to get tangled. By applying a breathing motion between the veneer and the next lower veneer to create a layer of air, that is, a gap, the sliding resistance between the veneers will be reduced and tangles will disappear. Next, the rotary blade is rotated by a rotary actuator, which is an independent drive source, at an angle of rotation within 3/3 rotations (in the embodiment according to this method, 3/3 rotations).
11 revolutions), and the rotary blade is in a stationary state and after the predetermined stroke descent crimping, after a delay time determined from the descent speed at the maximum unevenness difference that occurs in the veneer, the multiple rows The rotary blades are operated synchronously at the same time to ensure that the blades are aligned and transported to the conveyance line (auto feeder) for the next process.

装着されている。Hereinafter, an example of the laminated veneer unloading device fff (hereinafter referred to as the present device) according to the present method will be described. In FIG. A required number of hydraulic cylinders are suspended from the beam 3 so as to be able to freely slide in the horizontal direction, and a rotary actuator B, which is an independent drive source, is fixed to the tip of the rod 5. It is equipped with two rows of rotary blades with serrated blades. The rotary actuator B has an L-shaped guide plate protruding from its top that is slidably engaged with a guide plate 10 fixed to the fluid pressure cylinder L, so that it is positioned and moves up and down, and rotates. As shown in the cross section shown in Fig. 4, the blade is attached to the sleeve /2 which is secured to the rotating shaft 7 of the rotary actuator by a key // and is secured in double rows with the central disk /3 in between. , are fixed from the left and right sides by nuts 15 by clamping with presser plates/4', and are mounted symmetrically on the left and right sides of the rotary actuator B.

ものである。Next, to explain the unloading operation of the veneers, the veneers/7 stacked on the elevator/B are pressed with a predetermined pressure by the rotary blade that descends at a predetermined temperature of I°C, and the saw blade is crimped. However, the next moment, the pressure on the rod extrusion side of the fluid pressure cylinder was rapidly removed, and the rod was raised slightly (at a speed faster than the restoring speed of the laminated veneer), and the saw blade of the top layer was driven into the veneer. A gap is created between one plate and the next veneer, and then the rotary blade is rotated by 3/It in the unloading direction to transport veneer /7 a predetermined distance to the auto feeder. After alignment and unloading, the rod is raised to separate the veneer/7 from the rotary blade, and then the rotary actuator O is reversed to set the rotary blade to the starting position.Recovery 17.The veneer/7 is transported by the auto feeder 7K. According to this method, the p-atoyo is lowered again and the next cycle operation is started to feed the gap veneer /7 to the auto feeder /f. On the other hand, after crimping the rotary blade placed at a predetermined position with a predetermined pressure in a stationary state, the pressure is instantly released, creating a gap between the top layer veneers and reducing the sliding resistance between the veneers. , only the veneer /7 restrained by the rotary blade g is reliably carried out, and there is no "slippage" due to tangles as seen in the past, and all of the rotary blade edges in a stationary state are driven into the veneer /7. After completion, it is rotated in a limited, positive manner, so even if the veneer/7 has uneven undulations or there is some uneven synchronization in the rotary blade, the unloading can be reliably aligned at the final unloading position. This guarantees that the objective will be achieved and the veneer will be smoothly supplied to the next process.
