According to the invention of No. 1, a slider is slidably mounted perpendicular to the rails on rails installed parallel to both sides of a reference stand on which the tile to be measured is set, and the slider is provided with sliders that are attached to the center and end portions of the tile. A sensor that continuously detects the top height,
A sensor is installed at the end of the tile and continuously detects the height of the overlapping surface of the tile from below, and an X-coordinate sensor is mounted on the rail to measure the outside shape of the tile with a Y-coordinate detection mechanism. This invention is characterized in that a second slider with a detection mechanism is attached parallel to the slider.

(Embodiments) The present invention will be described in detail below with reference to illustrated embodiments.

Reference numeral 1 denotes a reference base having a smooth surface such as a surface plate on which the tile 50 to be measured is set, 2 and 2' a pair of rails provided in parallel on both sides of the reference base 1, and 3 a rail with wheels 4. This is a slider that is orthogonal to the rails 2, 2' that are slidably mounted on the rails 2, 2'.
The slider 3 has sensors 5, 5 that continuously detect the top surface height of the center and ends of the tile, and sensors 5, 5 that are located at the ends of the tile and continuously detect the height of the overlapping surface of the tiles from the bottom. A sensor 6 is provided whose position can be adjusted freely by holders 7 and 8. Each sensor 5, 6 has a detection rod 9, 10 that protrudes downward by a built-in spring, and at its tip there is a detection roller 11, 12 that contacts the upper and lower surfaces of the tile 50, respectively.
is provided. One of the sensors 5 and sensor 6 are located at the end of the tile as shown in FIG. 3 and detect the overlap height of the tile. The detection rods 9, A spring 13 is stretched between 10 and 10. 14 is slider 3
A rack is mounted on one side parallel to the rail 2, and 15 is a rack feeding motor equipped with a pinion that meshes with the rack 14. When this motor 15 is rotated, the slider 3 moves along the rail 2. , 2'. Further, a second slider 16 is slidably mounted on the rails 2, 2' in parallel with the slider 3 with wheels 17. The position of this second slider 16 is on rail 2'.
It can be electrically read by an X coordinate detection mechanism 18 attached to the lower side of the. Further, a tile outer shape measuring tool 19 is slidably mounted on the second slider 16, and its position on the second slider 16 is electrically determined by a Y coordinate detection mechanism 20 built into the second slider 16. can be read accurately. The tile outer shape measuring tool 19 supports a measuring rod 21 that is in contact with the outer peripheral surface of the tile 50 so as to be movable up and down. Note that 22 and 23 are the slider 3 and the second slider 16.
This is an engaging member protruding from the measuring rod 21, and then the second slider 16 is inserted into the engaging members 22, 2.
If the slider 3 and the second slider 16 are moved toward the slider 3 until they come into contact with each other, the slider 3 and the second slider 16 can be slid together on the rails 2 and 2'.
The sensor 5, the sensor 6, the X coordinate detection mechanism 18, and the Y coordinate detection mechanism 20 described above are each connected to a digital display device 24 as shown in FIG. 4, so that the measured values can be read. Each measured value is input to the arithmetic processing unit 25 using a microcomputer, and then input to the printer 26 or
It is also possible to configure a measurement system by outputting it to the CRT 27.

In order to measure the shape of the upper surface and overlapping surface 51 of the tile 50 with the above-described configuration, the tile 50
is set on the reference stand 1 with a pillow 60 interposed so that its length direction is parallel to the rails 2, 2' provided parallel to both sides of the reference stand 1, and the rails 2, 2'
Sensors 5, 5 continuously detect the top surface height of the tile 50 vertically installed on the slider 3 perpendicular to the slider 3, and sensors 5, 5 located at the end of the tile continuously detect the height of the overlapping surface of the tiles from the bottom side. After the sensors 6 to be detected are brought into contact with the top surface of the center, the top surface of the ends, and the overlapping surface 51 of the tile 50, the motor 15 moves the slider 3, which is slidably mounted on the rails 2 and 2', to the tile 50. from the right end position to the left end position in one X direction at a constant speed. During this movement, each sensor 5, 6 continuously measures the height of the top surface and overlapping surface 51 of the tile 50 on the moving path, so each sensor 5,
By reading the measured values of No. 6 into the arithmetic processing unit 25, the curved shape of the tile 50 can be measured at intervals of, for example, 1 mm. In addition, the second slider 16 with the X-coordinate detection mechanism 18 mounted on the rails 2, 2' is integrated with the slider 3 using the engaging members 22, 23 as described above, so that the X-coordinate of the slider 3 can be detected. It can also be read using the X coordinate detection mechanism 18 of the second slider 16. These measured values can be read by the measurer from the display device 24, and can also be printed out in numerical form from the printer 26, or can be displayed in an appropriate graph on the CRT 27. Therefore, the shape of the upper surface and overlapping surface 51 of the roof tile 50, which could not be measured accurately in the past, can be accurately measured in a short time. Next, to measure the outer shape of the tile, move the slider 3 to the right end of the rails 2, 2', and then move the second slider 16 with the X coordinate detection mechanism 18 mounted on the rails 2, 2'. The tile outer shape measuring tool 19 with the Y coordinate detection mechanism 20 mounted on the tile is manually moved to measure the tile outer shape on each end face of A, B, C, D, E, F, and G shown in FIG. The measuring rod 21 of the shape measuring tool 19 is brought into contact with the shape measuring tool 19 to measure the X coordinate or Y coordinate of each of these end faces. These measured values are read into the arithmetic processing unit 25 in the same way as above, and for example, the length of the tile 50 is determined from the measured values of A and E, the width of the tile 50 is determined from the measured values of D and G, and the width of the tile 50 is determined from the measured values of B and G. The working width of tile 50 is determined from the value, the machine length of tile 50 is determined from the measured values of E and F, and the working width of tile 50 is determined from the measured values of A and C.
The working length of the tile 50 is calculated from the measured values of C and F, and is digitized and displayed on the printer 26 or CRT 27, and therefore,
According to the present invention, the outer shape of the roof tile 50, which could not be measured accurately in the past, can be accurately measured in a short time. Note that it is preferable to measure the external shape prior to measuring the shape of the top surface and overlapping surface of the tiles.
Since the slider 3 and the second slider 16 are mounted on the top, it is convenient to perform these two types of measurements continuously.

(Effects of the Invention) As is clear from the above description, the present invention is capable of accurately measuring the shape of the top surface and overlapping surface of a tile and the outer shape of a tile in a short time, and is capable of measuring the shape of a tile in a short time. This tile shape measuring device that solves the above problems will greatly contribute to the industry.
