As shown in FIGS. 1 to 3, a support member 12 for placing and supporting a wood plate is provided at one end of the mount 11 of the scarf cutter 1 on the side of the carry-in roller conveyor 2. Reference numeral 12 denotes a fixed support 13 at one end, and a movable support 14 which can be tilted with respect to the fixed support 13 in a vertical plane.

One end of the movable support 14 is connected to and supported by the other end of the fixed support 13 by a horizontal connecting pin 15.
A turnbuckle type tilt angle adjuster (not shown) is provided. With this tilt angle adjuster, the movable support 14
Fine adjustment of the tilt angle is made to match the warpage of the wood plate to be cut.

On the fixed support 13 side, there are provided a first clamp device 21 for fixing the vertical position of the wood plate placed on the upper surface thereof and a second clamp device 22 for fixing the side surface thereof. Are located.

As shown in FIG. 4, the first clamp device 21 is sized so as to cover the upper surface of the fixed-side support table 13 and has a plurality of rubber band-shaped plates 23a on the lower surface thereof at predetermined intervals. And a plurality of (for example, four, four, front, rear, right and left) clamping cylinder devices 24 connected to both ends of the holding plate 23, and a second clamp. Device 22
As shown in FIG. 5, a positioning plate (also serving as a ruler for providing a right angle) 25 is disposed along one side edge of the pressing plate 23 of the first clamping device 21.
And a pressing cylinder device 26 which is disposed at the front and rear positions on the other side of the holding plate 23 and presses the wood plate toward the positioning plate 25 side.

Further, as shown in FIGS. 1 and 6, a large number of suction holes 31 are formed at the other end of the movable support table 14 over the entire surface thereof. Is connected at one end to the exhaust fan 32 and at the other end of a suction duct 34 in which a damper 33 is interposed. Due to the suction from the suction duct 34, the end of the wood plate body is forced to follow the surface of the movable support 14.

Further, a stopper device 35 for positioning the end of the wood plate is provided at the other end of the movable side support 14. That is, as shown in FIG. 7, the stopper device 35
At the other end of the swing lever 4, a swing lever 37 provided swingably via a horizontal support shaft 36 provided in a direction orthogonal to the transport direction, and is attached to a tip end of the swing lever 37. The stopper plate 38 and the stopper plate 38
A swinging device that swings the horizontal shaft 36 between a vertical position (a) as a stopper position thereof and a horizontal position (b) as a retreat position through which the electric cutting tool can pass. (Although not shown, for example, a hydraulic cylinder or a motor configured to be linked to an end of a horizontal support shaft by a sprocket, a chain, or the like).

Next, the cutting section 4 arranged above the support member 12 will be described. That is, the gantry 11
A support 41 erected on both sides of the central part of the body via a horizontal support shaft 42 arranged in a direction orthogonal to the transport direction,
In the vertical plane along the transport direction of the wood plate, the intermediate portion of the tilting frame 43 having a predetermined length is supported so as to be tiltable,
Both ends are fixed to the support 11a on the gantry 11 side by connection bolts 44 via connection fixing portions 43a.

A slide rail 45 having a predetermined length is disposed on the upper surface of the tilting frame 43. The movable body 4 is provided on the slide rail 45 via a slide member 46.
7 is slidably guided, and a sliding cylinder device 48 for sliding the moving body 47 is disposed on the tilting frame 43 side. For example, at the front, rear, left and right positions of the moving body 47, a guide rail
Is provided, and the elevating body 5 is guided by the elevating guide rail 49 via a slide member (not shown).
0, and the tilting frame 43 has
An elevating cylinder device 51 for elevating and lowering 0 is provided. Further, a rotary blade 52 for obliquely cutting the end of the wood plate is provided on the elevating body 50 via a bearing 53 so as to be rotatable. V pulleys 54 and 55 and V belt 56
An electric motor 57 is provided for rotating the motor through the motor. The electric motor 57, the V pulleys 54 and 55, the V belt 56, the rotary blade 52 and the like constitute an electric cutting tool.

The tilting frame 43 can freely adjust its tilting angle. That is,
A turnbuckle-type tilt angle adjuster 61 is provided between the tilt frame 43 and the gantry 11, as in the case of the movable support table 14, and the tilt frame 43 is
The hole of the connection bolt 44 for connecting the connection fixing portion 43a of the support 11 and the support 11a of the gantry 11 is formed into a long diameter.
Therefore, if these connecting bolts 44 are loosened and the turnbuckle as the tilt angle adjusting tool 61 is rotated,
A predetermined angle of the tilting frame 43 can be freely adjusted. That is, for example, it is possible to match the angle of the joining surface of the wood plate A for cutting.

Note that a hydraulic cylinder is used as each cylinder device in the above embodiment, and the hydraulic unit 73 is installed, for example, below the transport roller conveyor 2.

Next, the cutting operation of the joining surface of the wood plate will be described. First, the first and second clamp devices 21,
22 is in an unclamped state and the positioning plate 2
In a state where the plate 5 and the stopper plate 38 are set at predetermined positions, the wood plate A is moved toward the support member 11 by the carry-in roller conveyor 2. Then, after the wood plate A comes into contact with the stopper plate 38 and stops, the second
By the pressing cylinder device 26 of the clamp device 22,
The wooden plate A is positioned by being pressed against the positioning plate 25. Further, the holding plate 23 is fixed downward by the clamping cylinder device 24 of the first clamping device 21 to clamp one end of the wood plate A, and the air blower 32 is operated to operate the wood plate A. A is fixed by suction at the other end, and then the stopper plate 38 is moved to the retracted position (b).
Rock it.

Next, the electric motor 57 is operated to rotate the rotary blade 5.
2 and the cylinder device 4 for sliding.
8, the movable body 47 is reciprocated along the slide guide rail 45 of the tilting frame 43, and the support member 12
The end of the wooden plate A clamped to the side is cut diagonally. When the elevating body 50 on which the rotary blade 52 is disposed is sequentially lowered by the elevating cylinder device 51 at the same time as the start of cutting, the end of the wood plate A is cut at a predetermined angle.

As shown in FIG. 5, when the width of the timber plate A is small, between the side of the timber plate A and the positioning plate 25, and between the timber plate A and the pressing cylinder device 26
The adjusting plate 71 is inserted between the suction holes 31 and, when a gap is formed in the suction hole 31 as shown in FIG. 6, the gap is formed by a closing plate (for example, a rubber mat) 72. Will be blocked.

[0022]

As described above, according to the structure of the present invention, after the wood work is placed on the support member, and the positioning and fixing are performed by the stopper device and the clamp device, the electric cutting tool is operated. , And the moving body is reciprocated by the slide cylinder device,
If the elevating body is gradually lowered by the elevating cylinder device, without burdening the work as in the past,
In addition, even unskilled workers can automatically and quickly cut the end of the wood workpiece diagonally, and since there are many suction holes at the end of the support member,
The end of the wood workpiece can be forced to follow the surface of the support member, so that even if the wood workpiece is slightly deformed, cutting can be reliably performed.
