2. Description of the Related Art In recent years, machining of stone materials has been automated and it has become possible to easily process square or round shapes.
Especially after the automatic stone processing machine using the copyboard was developed,
Complex shapes can now be processed easily. However, the automatic stone machine using only one copying plate requires a concave curved surface or cannot perform complicated three-dimensional machining combining a concave curved surface and a convex curved surface.

For this reason, conventionally, there are two types of a horizontal copying plate and a vertical copying plate.
An automatic stone processing machine has also been developed that combines complicated three-dimensional plates and performs complicated three-dimensional processing such as the cap of the Olympic tower shown in FIG.
However, since this automatic stone processing machine uses a copying plate, the processing of the copying plate is troublesome, and the wear of the horizontal copying plate to which a large force is applied due to the constant contact with the dolly on which the stone is placed is greater than that of the vertical copying plate. Much faster. For this reason, the horizontal copying plate must be frequently manufactured, which increases the manufacturing cost and takes time to manufacture.

And then connected,
Following the movement of the cutter support 2 in the Y direction, the copy plate support

Reference numeral 50 is a control panel, which has a diameter setting device 51 for setting the radius of the curved surface R of the stone material 13 to be machined as shown in FIG. 5, and a radius setting device 51 for setting the radius. Calculating device 52 for calculating the positional relationship in the XY direction, a position detector 53 for detecting the position of the rotary cutter 3 in the Y direction, and the calculating device based on the position in the Y direction detected by the position detector 53. A signal output device 54 for calculating a position in the X direction at 52 and outputting a driving signal to the servo motor 8 attached to the moving mechanism of the carriage 1 is provided.

Next, the stone material is processed by the automatic stone processing machine having the above structure.
A case of processing 13 to form an Olympic tower will be described.
First, as shown in FIG. 2, the stone 13 is placed on the turntable 11 of the carriage 1 and the arm attached to the center support 14 is attached.
15 is lowered, and the center presser 16 at the tip is lowered to the center of the stone 13 and fixed. Separately from this, the vertical copying plate 45 formed in the finished vertical half-section shape is mounted on the copying plate mounting plate 44 to adjust the position.

After that, the control panel 50 is operated to adjust the center of the carriage 1 to set the reference in the X direction. Further, the Y direction slide frame 27 and the X direction slide frame 28 are driven to align the rotary cutter 3 to set the reference in the Y direction, and the guide rail 25 is adjusted to the width of the stone material 13 so that a limit switch (not shown) is provided. Adjust the position. Next, when the radius of the curved surface to be processed is set by the diameter setting device 51 of the control panel 50, the arithmetic unit 52 calculates the positional relationship in the XY directions based on the set radius.

After that, when the start switch of the control panel 50 is turned on, the motor 30 is driven and the rotary cutter 3 starts to rotate, and the motor 33 rotates, and the pinion gear 34 attached to the tip of the motor 33 is attached to the guide rail 25. The cutter support base 2 moves on the guide rail 25 by meshing with the formed rack 32. At this time, the position detector attached to the cutter support base 2
The position of the rotary cutter 3 in the Y direction is detected by 53,
This detected signal is output to the arithmetic unit 52 shown in FIG. 5, and the position in the X direction is calculated from the XY positional relationship determined from the preset radius.

This position signal in the X direction is output from the signal output device 54 to the servo motor 8 on the side of the carriage support 4 and rotated by a predetermined number. As a result, as shown in FIG.
The screw rod 7 is rotated via the boss 10, and the trolley 1 screwed with the boss 10 is moved by the action of the feed screw.
The upper stone material 13 moves to a predetermined X direction position.

When the cutter support base 2 further moves on the guide rail 25, the position change in the Y direction is sequentially detected by the position detector 53, and the change in the X direction is calculated based on this detection signal. The position signal causes the servo motor 8 to rotate a predetermined number of times to sequentially change the position of the stone material 13 in the X direction, and the upper surface of the stone material 13 is cut into a concave curved surface with a predetermined radius as shown in FIG.

At this time, since the X-direction slide frame 28 of the cutter support base 2 is constantly pressed against the carriage 1 by the cylinder 38 connected to the Y-direction slide frame 27, the rotary cutter 3 is made of stone material. It rotates by being pressed against 13, and the rotary cutter 3 escapes when a large force is applied.

When the cutter support base 2 moves on the guide rail 25 in this manner, the copy plate support base 42 connected by the connecting rod 46 also moves on the rail 41. When the cutter support base 2 reaches the limit switch and the switch is actuated, the motor 23 rotates a predetermined number of times, the screw rod 21a rotates via the bevel gear 22, and the screw rod 21b rotates via the shaft 24.

As a result, the left and right bosses 26, 26 threadedly engaged with the threaded rods 21a, 21b move by the action of the feed screw, and are guided by the guide stands 20a, 20b, and the guide rail 25 is moved to Z.
Descend in the direction. At this time, since the copying rod 39 is in sliding contact with the vertical copying plate 45 as shown in FIG. 4, the X-direction slide frame 28 of the cutter support base 2 moves in the X-direction following this,
The rotary cutter 3 at the tip moves backward to move the center of the radius.

In this state, the motor 33 reverses and the cutter support base 2 returns to the guide rail 25 in the opposite direction, and the position is detected while moving on the guide rail 25 in the Y direction. The position of 13 in the X direction moves and forms a curve of a concave curved surface while controlling the positional relationship in the X and Y directions relatively.

In this way, the cutter support base 2 reciprocates on the guide rail 25 and sequentially descends, and at the same time, the center of the radius is moved by the vertical copying plate 45, while the rotary cutter 3 and the stone material 13 are relatively moved. A concave curved surface curve is formed from the upper side of the stone material 13 while controlling the positional relationship in the XY directions to form one side surface of the five-wheel tower. After this, the carriage 1 and the cutter support base 2
To the initial reference position, then turn the turntable 11
The next side surface is processed by rotating once, and thereafter, concave curved surfaces are sequentially formed on the four side surfaces in the same manner to complete the Olympic tower shown in FIG.

Since the automatic stone processing machine provided with the vertical copying plate 45 causes the position change of the radius of the curved surface according to the height to be performed by the vertical copying plate 45 manufactured in the vertical half-section shape of the actual size, Since the arithmetic unit 52 of the control mechanism only has to calculate the XY relationship according to the radius of the curved surface, the structure is simple, complicated numerical value setting is not required, and the operation at the site is easy. Particularly, complicated three-dimensional processing in which a concave curved surface and a convex curved surface having a constriction are combined can be easily performed.

In the above embodiment, the cutter support base 2 is moved in the X direction by the copy plate mounting plate 44, moved in the Y direction by the guide rail 25, and moved in the Z direction by the guide stands 20a, 20b. Although the moving structure is used and the carriage 1 is configured to move on the rail 5 in the X direction, a combination thereof is shown, but the cutter support base 2 is moved in the X direction by the vertical copying plate 45 and the guide stands 20a, 20b. A two-dimensional moving structure that moves in the Z direction is adopted, and the carriage 1 is mounted on the rail 5 in the X direction and the Y on the rail orthogonal to the X direction.
A combination of two-dimensional moving structures that move in any direction may be used.

FIG. 7 shows another embodiment of the present invention.

The calculation device 52 for calculating the positional relationship in the XYZ direction based on the radius R set by the device 51 and the height Z of the curved surface part set by the height setting device 56, and the Y of the rotary cutter 3. A position detector 53 for detecting the directional position and a height detector 55 for detecting the height of the cutter support base 2 in the Z direction are provided. Further, the arithmetic unit 52 calculates a position in the X direction from the position in the Y direction detected by the position detector 53 and the height Z in the Z direction detected by the height detector 55, and the calculated position is calculated in the X direction. Servo motor 8
And a signal output device 54 that outputs a drive signal to the.

In this structure, the stone material processed by the diameter setting device 51
By setting the radius R of the curved surface portion of 13 and the height Z of the curved surface portion of the stone material to be processed by the height setting device 56, the three-dimensional positional relationship in the X, Y, Z directions is calculated by the arithmetic unit 52. Calculate With the height detector 55, the height Z of the cutter support base 2 in the Z direction
When the rotary cutter 3 moves on the guide rail 25 along the Y direction,
This position change is detected by the position detector 53 and the arithmetic unit 52
Output to.

The arithmetic unit 52 calculates X from the preset three-dimensional positional relationship in the XYZ directions based on the input YZ signal, and outputs this to the servomotor 8 of the carriage 1. A drive signal is output to move the carriage 1 for a predetermined distance to process a concave curved surface. In this way, the cutter support base 2 reciprocates on the guide rails 25 and sequentially descends to perform three-dimensional processing.

Therefore, the vertical copying plate 45, the copying plate supporting base 42 for supporting the vertical copying plate 45, the rail 41 on which the vertical copying plate 45 travels, the X-direction slide frame 28 of the cutter supporting base 2 and the like can be omitted to miniaturize the apparatus. In this case, as the moving mechanism, the cutter support base 2 is supported so as to be vertically movable in the Z direction,
The structure may be such that the dolly 1 is movably supported in the XY2 directions.
