Is engaged with the cutter cover 21. The cutter cover 21 moves up when the X-axis frame 11 moves down and comes into contact with the upper surface of the wood 50. By providing the thickness detection switch 22 above the cutter cover 21, the Y-axis motor 6 is driven to lower the Y-axis frame 8.
Rises in contact with the wood 50 and operates the thickness detection switch 22. Thereby, the height of the wood 50 is detected, and the reference position in the Y direction at which cutting by the cutter 15 is started is set.

In a normal operation, processing is performed on the basis of a black line (generally referred to as a black ink) marked on the center of the wood 50. The center of the processing is set in advance to the center of the vise, and since the vertical vice 2 and the horizontal vise 3 and 4 generally use the centripetal vise, the center of the processing is fixed to the vice 2 to 4 by fixing the wood 50 to the vice 2 to 4. If the woods 50 are fixed to the vice 2 to 4, the processing can be performed as it is.

FIG. 9 shows an example in which the center of the wood 50 is aligned with the center of the wood in the width direction.
The female processing of the stool, the male processing of the stool, the female processing of the stool, and the female processing of the large ant which is the side processing of the wood 50 are shown.

When processing the end face of the wood 50, an indicator 23 is provided below the front face 21a of the cutter cover 21 as shown in FIG.
The center position of the processing is determined by matching the values.

In the case of a mortise, the left and right sides 26 and 26 of the operation panel 24 are operated to move the cutter 15 by several tens of mm in the X direction by the X-axis motor 12.
The center position of the processing is determined by matching 2a with the indicator 23.

The home position return 27 is a switch for performing home position return so that the position of the cutter 15 can be recognized after the power switch is turned on.
The origin is returned in the order of the axes to determine the coordinates. Processing shape 2
At 8, the processing shape shown in FIG. 9 is selected, at the processing depth 29, the processing depth Hf from the upper surface of the wood 50 is selected, and at the wood width 30, the width of the wood 50 is specified. The automatic / manual 31 is a switch for switching between an automatic mode and a manual mode. When the manual mode is set, upper 32, lower 33, left 25, right 26, front 34, rear 35
The switches 15 can move the cutter 15 in the X, Y, and Z directions.

The tenon mortise 36 is used for tenoning a wood 50 at a position shifted from the center in the width direction. A switch for recognizing the processing center at a position where the cutter 15 has been moved left and right with the left 25 and right 26 switches except for the female processing of the large ant. Also, if the wood 50 is bent during the processing of a large ant scalpel, it is necessary to align the reference position of the cutter 15 with the black line attached to the surface of the wood 50. In this case, the front 34 and rear 35 switches are switches for recognizing the distance Zm of the cutter 15 moved in the front-rear direction. In operation 37, predetermined processing is started based on the selection conditions of the switches of the processing shape 28, the processing depth 29, the wood width 30, and the side tenon 36.

For cutting in each processing shape, the operation panel 2
4 and the thickness detection switch 22
Is received by the arithmetic processing unit 38, and after the coordinate values of the machining path are edited, the coordinate values are transferred to the numerical control unit 39. From the numerical controller 39, each X-axis driver 40,
The X-axis motor 12, the Y-axis motor 6, and the Z-axis motor 18 are controlled via a Y-axis driver 41 and a Z-axis driver 42, respectively. The amount of movement is coordinated by inputting a signal from the encoder of each axis to the numerical control unit 39 and counting it. The arithmetic processing unit 38 also performs control to stop the rotation of the cutter driving motor 16 via the relay 43.

Next, a procedure for cutting will be described with reference to FIGS. FIG. 7 is a flow chart in the case of the mortise “None”. After returning to the home position after turning on the power, selecting the processing shape, the processing depth, and the width of the wood, and turning on the operation 37, the upper surface of the wood 50 is detected by the board thickness detection switch 22. The position is read, and a processing path based on a processing shape, a processing depth, and a wood width is calculated by the arithmetic processing unit 38 and transferred to the numerical control unit 39 to perform cutting.

FIG. 6 is a flow chart in the case of the presence of a shift tenon. After returning to the home position after turning on the power, selecting the processing shape, the processing depth, and the wood width, the automatic / manual 31 is switched to manual, and the shift tenon 36 Turn on. Next, "Processing shape"
Is branched depending on whether it is other than a large ant (female) or a large ant (female). If it is not a large ant (female), the left 25 or the right 26 is turned on, and the black line 52 and the indicator 23 are turned on.
To match. The movement amount Lx at this time is -Xm ≦ Lx ≦ X
m, the warning device 44 is activated,
The movement of the X-axis frame 11 to the left or right is prohibited.

For example, in the case of performing a male processing of a stool (a stool portion width of 70 mm) with a width of wood of 50 mm (121 mm), if the movement amount Lx is 25.5 mm or more, the tenon shape of the stool portion is missing. , X coordinate Xm is 20 mm
Is set to When the movement amount Lx is within the above range,
When the automatic / manual 31 is switched to the automatic mode and the operation 37 is turned on, the upper surface coordinates of the wood 50 are read by the board thickness detection switch 22, and then the processing shape, the processing depth, the wood width and the X coordinate Xm are read.
Is read, and the processing path is edited by the calculation processing section 38 and transferred to the numerical calculation processing section 39 to perform predetermined cutting. In this case, if the movement in the Z direction is made by mistake, Zm is not edited.

In the case of a large ant (female), the front 34 or the rear 35 is turned on, and the black line 51 and the indicator 45 are aligned. If the Z coordinate Zm at this time exceeds the range of −Zm ≦ Lz ≦ Zm, the warning device 44 is operated to prohibit the Z-axis frame 17 from moving forward or backward.

The Z coordinate Zm is determined by the amount of bending of the wood 50 and varies depending on the horizontal vise 3 and the horizontal vise 4.
Since the maximum value is about 3 mm, Zm is set to 5 mm. When the Z coordinate Zm is within the above range, the automatic / manual 31 is switched to automatic and the operation 37 is turned on, and after reading the upper surface coordinates of the wood 50 with the plate thickness detection switch 22,
The processing shape, the processing depth, the wood width, and the Z coordinate Zm are read, the processing path is edited by the processing section 38, and the processing path is transferred to the numerical processing section 39 to perform predetermined cutting. In this case, Xm is not edited when the right-left movement is performed by mistake.

[0023]

According to the present invention, when the side mortise switch is instructed, only the left-right coordinates are used in the case of end processing from the "machining shape", and only the front-rear coordinates are used in the case of side processing. In addition, the amount of displacement between the left-right coordinate and the forward-backward coordinate is compared, and the amount of movement of the head portion is regulated. Therefore, erroneous processing is performed, and waste of wood is prevented.
