Abstract

PURPOSE:To rapidly and efficiently perform cutting work by providing a controlling means by which this position of the part necessary for cutting is properly moved in a calculated range on the traveling line of a rotary cutting edge in relation to the detection information in height of the surface of stone and the outer shape thereof due to a sensor. CONSTITUTION:When stone (w) is placed on a supporting base 13 and initial setting information is inputted to an operation board 15, the supporting base 13 is displaced to the specified position along a track 14. Then a saddle 5 is horizontally displaced along a beam member 3 by actuation of a motor 6. In this stage, a sensor 12 detects the vertical distance from the upper surface of the part becoming the cutting intended face of stone (w). This detection information is properly calculated and memoried in an instrument in a controlling means. At this time, the distance deviation between the position of the sensor 12 and the cutting point of a rotary cutting edge 8 is properly corrected, calculated and inputted. Then the rotary cutting edge 8 is accurately moved to the specified position in the vicinity of the upper surface becoming the cutting intended face of stone (w) by both the lower displacement of the beam member 3 due to rotation of a motor 4 and the horizontal displacement of the saddle 5 due to a motor 6. Thereafter the rotary cutting edge 8 is lowered and completely cuts the part of the cutting intended face of stone (w).

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an automatic cutting machine for stone, in which a rotary cutting blade is automatically moved across the stone to automatically cut the intended cutting area.

(Prior Art) There are two types of automatic cutting machines for stone, such as the following.

That is, one of them is capable of displacing the main cutting part equipped with a rotary cutting blade along a vertical plane in vertical and horizontal directions along the plane of rotation of the rotary cutting blade, and the other is capable of displacing the main cutting part equipped with a rotary cutting blade in vertical and horizontal directions along the rotation plane of the rotary cutting blade. In this case, a supporting stand for the stone to be cut by the rotary cutting blade is provided, and the supporting stand can be displaced in a direction perpendicular to the plane of rotation of the rotating cutting blade.

Another method is to make the above-mentioned cutting main part movable not only in the vertical and horizontal directions along the rotating surface of the rotary cutting blade, but also in the direction perpendicular to the said direction, and the support for the stone is fixed. Things and nothing.

Therefore, in these cutting machines, the rotary cutting blade is automatically displaced relative to the stone material in the vertical, horizontal, and front-back directions, so that the stone material can be automatically cut at any arbitrary position.

(Problem to be solved by the invention) When cutting stones, long pieces with uneven surfaces or polygonal pieces are often cut.
When this is done using conventional equipment, the rotary cutting blade will operate based on the initial setting information by the operator, regardless of the relative position of the stone and the rotary cutting blade, the external shape of the stone, the height of the stone surface, etc. Moreover, the cutting process is carried out by constantly moving and displacing a certain distance in the left and right direction, which is longer than the external dimensions, and for this reason, the rotating cutting blade selects a specific area of the stone surface, for example, a high part first. There are no measures taken to ensure that the cutting line is not run at the cutting line, or to avoid running the part that deviates from the cutting line as much as possible, which impairs the efficiency of work. .

An object of the present invention is to provide an automatic stone cutting machine that eliminates such problems and enables efficient work.

(Means for Solving the Problems) In order to achieve the above object, the present invention detects the distance from the upper surface of the material to be cut at a position in the vicinity of the rotary cutting blade at a location integral with the main cutting part of the stone cutting machine. control means for appropriately moving the position of the main cutting part on the traveling line of the rotary cutting blade to a range calculated in relation to the height of the stone surface and the stone external shape detected by the sensor; It is characterized by having the following.

(Function) Since the rotary cutting blade is moved appropriately to the range calculated in relation to the sensor detection information, unnecessary movement in the range not necessary for cutting is eliminated, and the area to be cut can be efficiently cut. Become something.

(Example) Hereinafter, specific examples of the present invention will be described with reference to the accompanying drawings.

Reference numeral 3 denotes a beam member installed between each of the pillars 2 and 2 so as to be movable up and down, which fixes the motor 4 at a proper position on the coupling member 2a, and is optionally moved up and down by the rotation of the motor 4.

Reference numeral 5 denotes a saddle attached to the beam member 3, which can be horizontally displaced along the member 3 by rotation of a motor 6 fixed to the saddle.

Reference numeral 7 denotes a main cutting part equipped with a rotary cutting blade 8 along a plane including the support columns 2 and 2, and is installed on the saddle 5. The main part 7 transmits the rotation of the motor 9 fixed to the saddle 5 to the cutting rotary blade 8 through an appropriate transmission mechanism 10 such as a belt transmission means, and the upper half of the cutting rotary blade 8 is It is covered with a safety cover 11 which is the same body as the saddle 5.

A sensor 12 is provided on the safety cover 11 of the rotary cutting blade 7 so as to coincide with the traveling line of the rotary cutting blade 8, and is used to detect the distance from the upper surface of the stone W to be cut. In this example, a sonic sensor is used as the sensor 12.

On the other hand, reference numeral 13 denotes a support base on which the stone material W to be cut is placed, and may or may not be movable in a direction perpendicular to the rotation plane of the cutting blade 8. That is, a track 14 is laid in a direction perpendicular to the rotating surface of the rotary cutting blade 8, and the support base 13 is guided by the track 14, and the support base 13 can be freely driven and driven by an appropriate motor provided on the support base 13.

Reference numeral 15 denotes an operation panel into which necessary initial setting information can be input, and this includes a mechanism for controlling each motor 4, 6, 9, and a system for calculating and temporarily storing information detected by the sensor 12. Based on the stored information, the motor 4.6.9
Control means are incorporated for proper operation.

Next, an example of the use of the device of the present invention will be described. First, a stone material W to be cut is placed on the support base 13, and the relative position of the surface to be cut and the device is appropriately adjusted and fixed.

Thereafter, appropriate initial setting information is input to the operation panel 15 to put the device into operation. As a result, the support stand 13 is displaced to a certain position along the track 14 while the rotary cutting blade 8 is positioned upwardly from the stone W, and then the saddle 5 is moved along the beam member 3 by the operation of the motor 6. For example, the sensor 12 detects the vertical distance from the upper surface of the part of the stone W that is to be cut during the horizontal displacement by a reciprocating distance, and the detected information is appropriately calculated and applied to an appropriate device within the control means. will be remembered. At this time, the distance deviation between the position of the sensor 12 and the cutting point of the rotary cutting blade 8 is appropriately corrected and input.

Next, each part of the device is operated based on the stored information, that is, the rotary cutting blade 8 first moves the beam member 3 downwardly due to the 40 rotations of the motor, and horizontally displaces the saddle 5 due to the rotation of the other motor 6. , a certain position near the upper surface of the stone W which is to be cut, that is, the position p shown in FIG.
1, the rotation of the motor 6 is changed to an extremely slow displacement speed (feeding speed during cutting), and the rotation of the motor 6 is changed to an extremely slow displacement speed (feeding speed during cutting), and the rotation is made horizontally with the saddle 5 for the required distance as shown by the dashed line g. Displaced by traveling to stone W
The planned cutting surface is cut with a cutting depth of several mm (the cutting depth S at this time is predetermined depending on the type of stone, etc.). As soon as the required distance has been cut, the rotary cutting blade 8 is moved downward by a certain amount of cutting S along with the beam member 3 by the rotation of the motor 4, and then the motor 6 is rotated in the opposite direction so that the saddle 5 is moved in the opposite direction. Since it is displaced in the horizontal direction at the feed rate during cutting, it travels and is displaced at the same time as this to cut the intended cutting surface of the stone W with a constant depth of cut S as described above. Thereafter, by repeating the same process, the rotary cutting blade 8 sequentially descends following the path indicated by the dotted chain '41Ag, and completely cuts the area of the stone W to be cut.

Now, if the stone material W shown in Fig. 4 is to be cut using a conventional device, the rotating cutting blade will always cut a distance longer than the total horizontal length 11 of the stone material W from the start of cutting to the end of cutting at the cutting feed rate. However, in the device of the present invention, as described above, the rotary cutting blade 8 moves only within the actually necessary range detected and calculated by the sensor 12. Therefore, the traveling displacement of the rotary cutting blade 8 within the range A indicated by the two-dot chain diagonal line in FIG. 4 is omitted, which improves the efficiency of the work.

6a and 16a, the beam member 3 can be displaced in a direction perpendicular to the rotating surface of the rotary cutting blade 8, and the saddle 5 has a main shaft that can be moved up and down by the rotation of a motor (not shown). One is that a lift 17 is provided, and the other is that the main cutting portion 7 is provided on the elevating body 17a of the lift 17, and the other is not provided.
