[Conventional technology]

BACKGROUND ART Conventionally, when a monument with a curved surface in a desired shape was manufactured using stone such as marble, only a skilled stone sculptor or the like would cut the stone into the desired shape using a mallet, a hand grinder, or the like.

[Problem that the invention seeks to solve]

Therefore, conventionally, manufacturing monuments and the like using stone materials such as marble has been inconvenient and time consuming and requires skill.

In view of this, an object of the present invention is to make it possible to manufacture a monument or the like of a desired shape using stone materials such as marble in a relatively short time and without requiring skill.

[Means for solving problems]

As shown in FIG. 1, the stone cutting device of the present invention has a diamond blade 1 arranged so as to be movable in the horizontal and vertical directions, separated by a predetermined distance, and moved together with the diamond blade 1 in the horizontal and vertical directions. 1 and a copying wheel 2 having the same diameter as the model 3, and by placing the copying wheel 2 along the model 3, it is possible to cut stone 4 into the same shape as the model 3 with this diamond blade 1. be.

[Effect]

According to the present invention, the diamond blade 1 draws the same trajectory as the copying wheel 2, so by moving the copying wheel 2 along the model 3, the diamond blade 1 moves the stone 4 in the same shape as the model 3. Can be cut into shapes.

〔Example〕

Hereinafter, one embodiment of the stone cutting device of the present invention will be explained with reference to FIG.

In FIG. 1, reference numeral 1 indicates a diamond blade having a diameter of, for example, 60 cm and a thickness of 5 mm. It is configured to be rotatably driven by a rotary drive motor 6 fixedly provided at the top via gears or the like. An intermediate portion of the support tube 5 is supported movably in the vertical direction by a first sliding body 8 provided on the beam 7 so as to be slidable in the horizontal direction. Further, a copying hydraulic cylinder 9 is integrally fixed to this first sliding body 8, and the tip of a piston rod 10 of this copying hydraulic cylinder 9 is fixed to the lower end of this support tube 5. The vertical position of the diamond blade 1 is controlled by a piston rod 10 of a hydraulic cylinder 9.

Reference numeral 2 denotes a copying wheel, and this copying wheel 2 has the same diameter as the diamond blade 1, for example, 60 cm in diameter. The position detecting rod 11 is fixed in relation to the styler lath 12 of the
The second sliding body 13 is supported movably in the vertical direction on the sliding body 13, and the first sliding body 8 is supported on the beam 7.
It is provided integrally and slidably in the horizontal direction at a predetermined interval. In this case, since the copying wheel 2 is provided in conjunction with the styler 12 of the copying hydraulic cylinder 9, the vertical movement position of the diamond blade 1 is controlled to be the same as that of the copying wheel 2. In this case, the copying wheel 2 does not always move downward, and when it comes into contact with the model 3, the downward movement stops. Furthermore, since the copying wheel 2 and the diamond blade 1 are fixed at a predetermined distance apart in the horizontal direction via the first and second sliding bodies 8 and 13, the copying wheel 2 and the diamond blade 1 are Horizontal movement is the same. The first and second sliding bodies 8 and 13 are configured to repeatedly reciprocate horizontally along the beam 7 by a horizontal drive motor 14 provided in association with the beam 7.

Further, both ends of this beam 7 are vertically slidably supported by columns 15a and 15b fixed to the ground, and are screwed into screw rods 16a and 16b.
Due to the rotation of the threaded rods 16a and 16b, this beam 7
is made to move in the vertical direction. The screw rods 16a, 16b are rotated by a vertical drive motor 17 fixed to the upper part of the column 15a via gears or the like. Also, 18 is stone 4
The cart 18 is configured to move in a direction perpendicular to the beam 7. Reference numeral 19 denotes a model truck on which the model 3 is placed, and this model truck 19 is configured to move together with the stone truck 18. In this case, a motor 6 for driving the rotation of the diamond blade 1, a motor 14 for driving the horizontal direction, a motor 17 for driving the vertical direction, and a cart 18,
19 is driven in accordance with a predetermined control signal from a control device provided elsewhere. Further, in this example, a micro switch or the like is provided in connection with the position detection rod 11, so that when the copying wheel 2 is in contact with the model 3 from beginning to end when moving in the horizontal direction, a machining end signal is issued. .

Next, referring to FIGS. 3 and 4, we will explain the case where the stone 4 is cut into the same shape as the model 3 (the shape indicated by the dashed line in FIG. 3). is placed on the trolley 18, and the model 3 is placed on the model trolley 19. In this case, the model 3 is made of polystyrene foam, wood, or the like, which is relatively easy to process into a desired shape. Furthermore, this model 3 may be already formed. In this case, the positional relationship between the model 3 and the stones 4 is such that when the copying wheel 2 is moved along the outer shape of the model 3, the diamond blade 1 moves to a predetermined position in the space partitioned by the stones 4.
Further, the Z direction is the direction in which the cart 18 moves, the X direction is the direction in which the diamond blade 1 moves horizontally,
The Y direction is the direction in which the diamond blade 1 moves vertically.

First, referring to FIG. 3, the roughing process will be explained. At this time, the positions of the stoppers 20a and 20b provided on the beam 7 are determined based on the width of the stone 4, that is, the width of the model 3. At this time, when a detection device such as a micro switch provided on both sides of the second sliding body 13 comes into contact with the stoppers 20a and 20b, the direction of rotation of the horizontal drive motor 14 is reversed and the diamond blade 1 moves back and forth. Do as you would.

During this rough pulling, first the vertical drive motor 17
is driven to lower the beam 7 to a predetermined position, for example, a position sufficient to cut into the stone 4 considering the length of the piston rod 10, and then this diamond blade 1 is lowered.
Stone 4 is rotated and reciprocated in the horizontal direction
This is repeated until the copying wheel 2 moves downward and comes into contact with the model 3 from beginning to end in one horizontal direction. In this case, the diamond blade 1 is brought into alignment with the copying wheel 2 in the vertical direction by the copying hydraulic cylinder 9. Further, in this case, the depth into which the stone material 4 can be cut is determined by the diameter of the diamond blade 1, and is, for example, 20 cm in this example.

When this machining end signal is obtained, the vertical drive motor 17 is first reversed to raise the beam 7 sufficiently, then the carts 18 and 19 are moved by 15 mm, and then the above-described operations are repeated in sequence. In this case, since the thickness of the diamond blade 1 is 5 mm in the cut portion, the 10 mm stone 4a and the 5 mm groove 4b are repeated, but by removing the 10 mm stone 4a with a hammer etc. The shape is completed.

When finishing is to be performed next, the above-mentioned operation is repeated, but in this case, the moving pitch of the carts 18 and 19 is set to 5 mm, which is the thickness of the diamond blade 1.

Once this finishing is completed, the stone 4 can be cut into the same shape as the model 3, as shown in FIG.

As described above, according to this example, the stone material 4 such as marble can be cut into the same shape as the desired shape of the model 3 using the diamond blade 1. Therefore, according to this example, it is possible to manufacture a monument etc. in a desired shape in a very short time using stone materials such as marble, and since the model 3 is formed from Styrofoam, wood, etc. which are relatively easy to process, it requires a skilled mason, There is an advantage that a desired shape can be obtained without relying on a sculptor or the like, and a monument or the like made of stone such as marble can be relatively easily obtained in a desired shape.

In the above-mentioned embodiment, a stopper 20a is provided on the beam 7 to prevent the movement of the diamond blade 1 in the horizontal direction
and 20b are provided so that this movement width is repeated at regular intervals. However, when the model 3 has an inclination in the horizontal direction X as shown in FIG. For example, a micro switch may be provided to detect that the copying wheel 2 has come into contact with the model 3, and then the horizontal drive motor 1
4 is reversed and the trajectory of the diamond blade 1 relative to the stone 4 is as shown by the two-dot chain line 1a in FIG. You can cut into stone 4 with .

Furthermore, the present invention is not limited to the above-described embodiments, and it goes without saying that various other configurations may be adopted without departing from the gist of the present invention.

〔Effect of the invention〕

According to the present invention, it is possible to cut a stone material 4 such as marble into the same shape as the model 3 having a desired shape using the diamond blade 1, so according to the present invention, a stone material such as marble or the like having a desired shape can be cut into a monument in a very short time. Model 3 can be formed from styrofoam, wood, etc., which are relatively easy to process, so you can obtain the desired shape without relying on skilled stonemasons, sculptors, etc., and you can create stone materials such as marble in the desired shape. There is the benefit of being able to obtain monuments, etc. based on these relatively easily.
