The guide rail 4 is provided on the front side of the base frame 1. A cutter 5 is attached to the guide rail 4 so as to be movable along the guide rail 4. The cutter 5 has two motors 6 and 7, a rotary blade (disc-shaped saw) 8 that is connected to the motor 6 and is rotated by the drive of the motor 6, and a pinion 9 that is connected to the motor 7. is doing. The rotary blade 8 is arranged in parallel with the vertical shaft 3, and the pinion 9 is adapted to rotate about an axis orthogonal to the vertical shaft 3. On the other hand, a rack 10 is fixed at a predetermined position on the guide rail side of the vertical shaft 3 so as to face the guide rail 4. The pinion 9 is meshed with the rack 10.

On the other hand, a holding mechanism 11 is provided on the side of the vertical shaft 3 opposite to the rack 10. The holding mechanism 11 is arranged in parallel with the vertical shaft 3 at a predetermined position on the opposite side of the vertical shaft 3 from the rack 10 and has a cylinder mechanism structure in which the base end is rotatably attached to the vertical shaft 3 via a horizontal shaft. 12, a lever 15 having a base end rotatably connected to the tip of a piston rod 13 of the cylinder mechanism 12 and an intermediate part rotatably supported by a support pin 14 at a predetermined position of the vertical shaft 3. A holding plate 16 made of an elongated rectangular plate that is provided along the vertical shaft 3 on the base frame 1 side of the cylinder mechanism 12 and the lever 15, and is rotatably attached to the tip end portion of the lever 15, and a diagram of the vertical shaft 3. The auxiliary pressing member 17 is attached below the tip of the lever 15 in FIG. The auxiliary presser 17 includes a U-shaped frame 18 fixed to the vertical shaft 3 and a push rod 19 provided in the U-shaped frame 18 so as to be capable of advancing and retreating with respect to the pressing plate 16 and fixed at a predetermined position. It consists of.

Further, a first limit switch 21 is fixed to a lower portion of the vertical shaft 3 (a lower portion of the horizontal shaft 2 in FIG. 1), and the first limit switch 21 has a cutter 5 down. After the rotary blade 8 has passed down the horizontal shaft 2 and the predetermined portion of the cutter 5 presses the contact of the first limit switch 21, the cutter 5 can be inverted and moved upward (to the cylinder mechanism 12 side). Has been done. Further, a second safety limit switch 22 is provided below the first limit switch 21. Further, the third and fourth limit switches 23 and 24 are provided above the cylinder mechanism 12 of the vertical shaft 3. In addition, 27 is a mounting plate for the vertical shaft 3 of the cylinder mechanism 12, and 28 is a set screw.

When the cutter 5 is at the uppermost position of its moving range, the cylinder mechanism 12 is in the contracted state, and the pressing plate 16 is separated from the front surfaces of the base frame 1 and the receiving rod 1b, the pressing plate 16 and the pressing plate 16 are separated from each other. When the edge of the plywood to be cut is inserted between 16 and 16, and a certain switch is turned on, the cylinder mechanism 12 is extended, the lever 15 rotates, and the pressing plate 16 advances to the base frame 1 side. The plywood 25 is pressed against the base frame 1 and the receiving rod 1b by the pressing plate 16. At this time, the push rod 19 is moved to the plywood 25 side and fixed by the set screw 28 so that the pressing plate 16 can be prevented from rising.

Next, when another switch is turned on, the rotary blade 8 rotates, and when another switch is turned on, the rotating rotary blade 8 descends and cuts the plywood 25. The cutter 5 that has cut the plywood 25 is further lowered, and a part thereof turns on the first limit switch 21. Then, the cutter 5 reversely moves, that is, rises and turns on the third limit switch 23 above it. This stops the cutter from rising and turning the switch stops the rotating blade. Here, when another switch is turned off, the cylinder mechanism 12 is contracted, the lever 15 is rotated accordingly, and the pressing plate 16 is retracted from the base frame 1 and the receiving rod 1b and separated from the plywood 25. Then, the plywood 25 is extracted from between the base frame 1 and the receiving rod 1b and the pressing plate 16.

In the above operation, if the cutter 5 descends beyond the first limit switch 21, the cutter 5 turns on the second limit switch 22 and the cutter 5 stops, which is safe. . In addition, if the cutter 5 rises and rises above the third limit switch 23, the cutter 5 turns on the fourth limit switch 24 and the cutter 5 stops, which is safe.

In the above embodiment, the push rod 19 is used to prevent the pressing plate 16 from rising, but the present invention is not limited to this, and a lever similar to the lever 15 is connected below the lever 15 in series. Alternatively, the lever may be linked to the lever 15 to perform the same operation.
