The rotational force of the motor 7 is transmitted to the support shaft of the roller 3 at the left end in FIG. 1 via the sprocket and the chain, and then to the central roller support shaft via the sprocket and the chain, and then to the roller support shaft at the right end. Is done.

The table 1 is formed with a plurality of (four in the figure) grooves 10 extending from the left end to the right end in the figure and provided at appropriate intervals. An endless chain 11 is fitted in the groove 10, and constitutes a second plywood transfer device 12 for feeding the plywood 4 on the table 1 forward in the traveling direction. The second plywood transfer device 12 includes the chain 11 whose upper part is fitted at a position slightly lower than the upper surface of the table 1, and an end of the plywood 4 which is formed to protrude radially outward from the chain 11. And a driving means such as a motor for rotating the chain 11 clockwise.

A plurality of rollers 15 are provided at a front portion of the table 1 so as to be parallel and vertically opposed to each other at intervals in the short direction of the table 1, and as shown in FIG. 15 is rotated clockwise by the motor 14, so that the first and second plywood transfer devices 5,
A third plywood transfer device 16 configured to further transfer the plywood 4 transferred by the ply 12 forward. An opening 17 is formed in a portion where the upper and lower rollers 15 face each other.

In front of the third plywood transfer device 16,
Two cutting machines 20 for cutting the plywood 4 in the longitudinal direction are supported in each frame 19 and provided in series in the short direction of the table 1. The cutting machine 20 includes a cutter 21 supported on a shaft and a motor 22 for rotating the cutter 21.
And a cutter cover 2 provided to surround the cutter 21.
3 and a fan (not shown) which is provided on a shaft supporting the cutter 21 and discharges chips discharged at the time of cutting upward. The cutter 21 has a lower part protruding downward from a lateral groove 25 formed in the table 1. Further, as shown in FIG. 4 , the cutting machine 20 is provided movably in the short direction of the table 1 by being guided by a guide rail 27 extending from a frame 30 described later, and is provided above the cutting machine 20. When the cylinder 28 is pushed upward by the cylinder 29, the cylinder 28 engages with the pins 31 of the frame 30 so that the table 1 can be positioned in the short direction. In addition, one of the two cutting machines 20 (the left cutting machine 20 in FIG. 4) is vertically movable. It is raised upward and becomes a rest state.

Further, the frame 30 is erected in front of the table 1, and a plurality of rollers 35 are arranged on the frame 30 so as to face in parallel with each other at intervals in the short direction of the table 1. As shown in FIG. 2, the lower roller 35 is rotated clockwise by the common motor 14 via a power transmission member such as a chien or a sprocket, so that the cut mixture 4 is cut. Is transported further forward.

Between the cutter 21 of the left and right cutters 20 and the upper and lower rollers 35, 35 in front of the cutter 21, a plate 39 for fitting into the cutting groove 38 of the plywood 4 cut by the cutter 21 is provided. And the lower end thereof is provided to protrude downward from the groove 20aa of the plywood holder 20a attached to the cutting machine 2. The plate 39 is a frame 19 supporting the cutting machine 20.
The thickness thereof is set to a value slightly smaller than the width of the cutting groove 38 of the plywood 4 cut by the cutter 21.

Next, a case where the plywood 4 is cut by the plywood cutting device having the above-described configuration will be described. The first plywood transfer device 5, the second plywood transfer device 12, and the third plywood transfer device 16 are each operated, and the cutter 21 of the cutting machine 20 is turned. When the plywood 4 is placed on the table 1 in this state, when the plywood 4 is engaged with the rollers 3 of the first plywood transfer device 5, the plywood 4 is pulled back by the rollers 3 and is It is pressed against the plate 2. Since the rollers 3 are arranged at an angle, the plywood 4 is simultaneously transported forward in the traveling direction.

Next, the claws 13 provided on the chain 11 of the second plywood transfer device 12 engage with the ends of the plywood 4 and are pushed by the claws 13 so that the plywood 4 is transferred forward in the traveling direction. You. And the plywood 4 being transferred is the cutting machine 2
When it reaches zero, it is cut in the longitudinal direction by the rotating cutter 21, and is then discharged by being sandwiched between the front rollers.

When the plywood 4 is cut by the cutter and sandwiched by the rollers 15, the plate material fits into the cutting grooves 38 of the plywood 4, thereby restricting the movement of the plywood 4 in a direction perpendicular to the direction of travel. Therefore, the plywood 4 does not move right and left even when it receives forces from the cutter 21 in various directions. For this reason, the cut surface of the plywood 4 is kept flat.

In order to obtain a plywood 4 having a different width, for example, when changing the cutting position of the plywood 4, the cylinder 29 is actuated to lower the piston rod as shown in FIG. Then, the cutting machine 20 is moved right and left along the guide rail 27, and when it comes to an appropriate position, the cylinder is operated again to move the cylinder 28 upward and fit into the pin 31. In this manner, cutting may be performed again with the cutting machine 20 set at an appropriate position.
