DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION This invention is, measure the shape of the tile
On the equipment. More, the invention relates to measuring apparatus for measuring the measurement of the outer shape of the tile accurately and simple and convenient.

[0002] In this specification, the following defined terms are used in the following sense. The "front-back direction" means the direction of the head side and the butt side of the roof tile, for example, and the "left-right direction" means the direction of the roof side and the collar side of the roof tile, respectively.

[0003] In the art, the layered portion of a tile during roofing work is referred to as the "overlapping surface" of the tile. To be precise, the layered portion of the tile does not come into surface contact with each other, and is placed on the tile surface on one front side. On the other hand, the end of the back side of the other tile, for example, the part end from the crosspiece side to the collar side on the head side comes into contact as a line, so it should be originally called "overlapping line part", but in the industry, The term "surface" is commonly used, and the term "overlapping surface" is used.

[0004] Further, the term "overlapping surface" refers to four laminated portions of four tiles adjacent to the periphery of one tile when a substantially rectangular tile having four sides is laid on the roof. ,
A strip-shaped part and a line-shaped part which are symmetrically addressed to two places as L-shaped parts near the front and back contours of one roof tile. Although the upper end portion of the side is not laminated on the tiles arranged vertically, its height occupies an important factor in the roofing, so that its height is also measured according to the overlapping surface.

On the front side, a portion that appears in a band shape with a constant width from the crosspiece side to the collar side on the butt side is denoted by a reference numeral for convenience of description, and is referred to as a "butt side overlapping surface E". Also,
On the collar side, a portion that appears in a band shape with a constant width from the butt side to the head side is denoted by a reference numeral for convenience of description, and is referred to as a “collar side overlapping surface G”. On the back side, a portion that appears linearly from the crosspiece side to the collar side at the head side end is denoted by a reference numeral for convenience of description, and is referred to as “head side lower end portion F”. Further, a portion appearing linearly from the butt side to the head side at the cross-side end is denoted by a reference numeral for convenience of description, and is referred to as a "cross-side lower end portion H" (see FIGS. 10, 11, and 12).

[0006] Although not a laminated portion as described above, a linear portion extending from the butt side to the head side at the collar side end of the front tile W is referred to as a "collar side upper end portion I" for convenience of description below. The height also has a significant effect on the roofing, and the specification also refers to this point as a measurement target portion (see FIG. 12).

However, in this specification, unless otherwise noted, for convenience of explanation, a “butt side overlapping surface”, a “collar side overlapping surface”, a “head side lower end portion”, a “cross side lower end portion” and a “collar side” Each part to be measured at the upper side portion is collectively referred to as an "overlap surface".

Needless to say, other measurement points defined in the so-called JIS standard are also measured. Incidentally, the width and length of the tile is W, the it to the width and length and valleys of the working dimensions are subject to the measurement, is equipment that can perform measurements also for the portion other than the above if necessary precaution Reveal for.

2. Description of the Related Art In the manufacture of tiles, clay is kneaded, and so-called tile wasteland extruded from a clay kneading machine is press-molded.
It is known that a press-molded tile base is dried, glazed if necessary, and further manufactured through various steps such as firing.

In recent years, tile production equipment has been automated by mechanization. However, as described above, many steps are required for commercialization, and strict control of each step is required to improve tile quality. I have.

In particular, the production of tiles is based on the property of using clay containing water as a raw material, so that it is inevitable that distortions are generated in the shape of the tiles by a drying treatment and a firing treatment.

[0012] In addition, distortion occurs due to the inherent habit (physical properties) of the clay itself, causing variations in shape. When the tiles with variation were used as they were for roofing, gaps were generated at the tiled portions of adjacent tiles.

As a result, not only is the appearance of the roof impaired, but also rainfall enters through the gaps between the tiles to cause water leakage, and the roofing work is complicated. In addition, a tile manufacturer, which is a Japanese industrial standard display factory, must constantly measure and record measurement data of the shape and dimensions of the tile based on the JIS standard.

Therefore, at the production site by the conventional automation, the sampling inspection is performed to maintain the quality of the tile, and based on the inspection result, the equipment and the equipment are adjusted and optimized to improve the quality. We have tried (Tokuhei 2-2
1725 publication).

Is measured.

[0015] However, in the equipment conventional for this kind, a number of sensors provided in the slider, is where a structure is a problem in operability and measurement accuracy as well as a complex.

06 to the arithmetic processing mechanism 12
Is provided.

Next will be described the operation of the embodiment of the apparatus of the invention below. Prior to measuring the shape of each part of the tile W, a preparation process is performed to obtain the measurement accuracy of the shape of the tile W.
The tile W is placed horizontally on the support members 36, 36, 38, 38 of the turntable 22.

At this time, the tile W is placed so that the side surface on the side of the beam is parallel to the side surface on one side of the base 18. Whether tile W is placed horizontally in a given position is possible by utilizing a measuring instrument such as an appropriate jig, thus Preparation before measurement is to be ended.

Next, in order to set a reference value (origin) in the horizontal direction of the tile W, the main measuring unit 78 and the auxiliary measuring unit 74 are slid, and the measuring surface 120 of the main measuring element 122 of the main measuring unit 78 is moved.
Then, the measuring surface 86 of the auxiliary tracing stylus 84 of the auxiliary measuring section 74 is brought into contact with the switch, and the switch 144 provided in the main measuring section 78 is operated (see FIG. 8).

When the switch 144 is operated, the position data is read by the encoder 88 for measuring the horizontal direction, transmitted to the arithmetic processing mechanism 12 through electric wiring, arithmetically processed and stored as the reference value 0. . Therefore, this contact state becomes the reference value 0 in the left-right direction of the tile W.

Next, the positioning bar 52 is rotated so that a predetermined surface thereof faces the upper surface. In the case of this embodiment, the guide rail 48 of the portal 50 for measuring the width and length of the roof tile W, the width and length of the working dimension, and the depth of the valley specified in JIS standards is provided on this surface. A positioning hole is provided so as to perform positioning with respect to.

Then, in order to measure the width and working dimensions of the tile W, the portal 50 is run on the guide rail 48, and the portal 50 is inserted into a positioning hole indicating the position where the width of the tile W is measured. The positioning lever 68 is fitted. The measurement surface 86 of the auxiliary tracing stylus 84 is brought into contact with the auxiliary measurement unit 74 by moving the auxiliary measurement unit 74 to the beam side surface of the tile W placed with the gate 50 in this position, and the measurement switch 144 is operated. .

When the measuring switch 144 is operated, the encoder 88 for measuring the horizontal direction reads the position of the wire 90, and this position data is transmitted through the electric wiring to the arithmetic processing mechanism 1.
2, and are subjected to arithmetic processing and stored as measurement data. Therefore, the width dimension of the tile W can be obtained as measurement data.

Similarly, the measurement is performed by fitting the positioning lever 68 into the positioning hole indicating the position where the width of the dimension is measured by operating the portal 50 and bringing the main measuring element 122 and the auxiliary measuring element 84 into contact with the tile W. The switch 144 is operated. The position data at this time is processed in the same manner as described above, and the width of the working dimension is stored as measurement data.

Next, the gate-shaped portion 50 is placed in the above-described position and the tile W
Measure the depth of the valley. The measuring switch provided on the lower end of the measuring plate 114 of the main measuring unit 78 is brought into contact with the upper surface near one side surface of the tile W to operate the measuring switch 144. After operating the measuring switch 144, the roller 136 of the tracing stylus 128 is rolled from the crosspiece to the valley and the collar.

When the roller 136 is rolled so as to always contact, the main measuring unit 78 changes due to a change in the vertical position of the contact point.
When the measuring plate 114 and the elevating body 100 cross the surface of the roof tile W, the vertical position is read at a constant gap. That is, the tracing stylus 128 crosses the surface of the tile W
, The vertical position data is measured at a fixed interval of the trajectory of the tracing stylus 128.

The mechanism for reading the position data from the roller 136 will be described with reference to FIG. 9. When the contact between the roller 136 and the tile W is taken as a point, the contact point is referred to as the roller. When the tangent of the circle represented by 136 is drawn, the intersection between the line segment perpendicular to the tangent and the center of the roller 136 is the measurement point.

In the case of this embodiment, the measuring points are kept at an arbitrary interval of about 1 mm. Therefore, when the roller 136 of the tracing stylus 128 rolls on the surface of the tile W, the interval is about 1 mm. The vertical measurement of the tile is performed. The position data at each measurement point is processed by the processing unit 12 and stored as measurement data. The display mechanism 14 or the printer 16 can connect these measurement points with a straight line and display them approximately on the surface of the tile W.

The depth of the valley can be obtained by connecting the cross section of the tile W and the highest part of the collar with a straight line, and subtracting the deepest part of the valley of the tile W. This also applies to the arithmetic processing unit 12.
Is calculated and stored.

Next, the length of the tile W and the length of the working dimension are measured. The rotating table 22 on which the tile W is placed is released by releasing the stopper 24 provided on the base 18 and rotated counterclockwise 90 degrees horizontally. When rotated, the bottom side of the tile W is the base 18
And the head side is located on the other side on the base 18, and the turntable 22 is fixed by the stopper 24.

Then, the positioning bar 52 is switched to another surface. This surface is provided with a positioning hole indicating a measurement position for the length of the roof tile W and the width of the working dimension specified in the JIS standard. The gate 50 is moved again, and the positioning lever is provided in the positioning hole indicating the position where the length of the tile W is measured.
68 is fitted.

As described above, the main tracing stylus 12 of the main measuring section 78
The measurement data 120 is placed on the head side of the tile W and the measurement surface 86 of the auxiliary tracing stylus 84 of the auxiliary measurement unit 74 is brought into contact with the side of the tail of the tile W, and the position data is measured by the measurement switch 144. Is operated, and the arithmetic processing mechanism 12 performs arithmetic processing to store the measurement data.

When the measurement of the length of the tile W is completed, the length of the working dimension is measured. However, since the length is basically the same as the length of the tile W , the description is omitted.

In this way, measurement data can be obtained for the width and length of the roof tile W defined by the JIS standard, the width and length of the working dimension, and the depth of the valley. If necessary, the measurement data is displayed on the display mechanism 14 as a numerical value, and the printer 1
6 can be printed.

Next, the overlapping surface of the tile W is measured. The stopper 24 on the base 18 is released again, and the turntable 22 is moved 90 degrees.
Rotate clockwise clockwise and return to the
To fix the turntable 22.

Then, the positioning lever 68 of the portal section 50 is used.
Is released and the positioning bar 52 is rotated so that a predetermined surface thereof faces upward. In the case of this embodiment, a positioning hole 50 for measuring the tail-side overlapping surface and the head-side lower end is provided on this surface.

First, measurement is performed on the buttocks side overlapping surface. The portal 50 is moved to the positioning hole 56 for measuring the buttocks side overlapping surface, and the portal 50 is fixed by the positioning lever 68. In this state, the main measuring section 78 is moved to the vicinity of the side surface of the butt side overlapping surface on the side of the beam, and is brought into contact therewith.

After the contact, the measuring switch 144 is operated to roll the roller 136 of the tracing stylus 128 to the side of the collar toward the collar. If the roller 136 is rolled so as to always contact, the main measuring unit 78 changes due to a change in the vertical position of the contact point.
When the measuring plate 114 and the elevating body 100 cross the surface of the roof tile W, the vertical position is read at a constant gap. That is, the tracing stylus 128 crosses the surface of the tile W
, The vertical position data is measured at a fixed interval of the trajectory of the tracing stylus 128.

This is the same as the method of measuring the valley of the roof tile W first. However, if it is described again, the mechanism for reading the position data from the roller 136 will be described with reference to FIG. To explain, assuming that the contact between the roller 136 and the roof tile W is a point, if a tangent of a circle represented by the roller 136 is drawn at the contact point, a line segment in a direction perpendicular to the tangent and the tangent are drawn. -The intersection with the center of the line 136 is the measurement point.

In this embodiment, the measuring points are kept at an arbitrary interval of about 1 mm. Therefore, when the roller of the tracing stylus 136 rolls on the surface of the tile W, the measuring point is spaced at an interval of about 1 mm. The vertical measurement of W is performed. The position data at each measurement point is processed by the processing unit 12 and stored as measurement data.

The display mechanism 14 or the printer 16 can connect each measurement point with a straight line and display it approximately on the surface of the tile W. Of course, measurement data based on measurement points at intervals of about 1 mm can be obtained.

Next, the head lower end is measured. The positioning lever 68 of the portal 50 is released again, the portal 50 is moved to the positioning hole 56 indicating the position where the lower end of the head is measured, and the portal 50 is fixed by the positioning lever 68.

The roller 140 of the tracing stylus 132 provided toward the portal 50 of the main measuring section 78 is brought into contact with the beam side at the lower end of the head side, and in the state of being brought into contact therewith, to the collar side. Roll. As described above, position data obtained at measurement points at regular intervals
Is processed by the arithmetic processing unit 12 in the same manner as described above.
Measurement data is obtained and stored.

Next, measurements are made on the collar-side overlapping surface, the lower end of the crosspiece, and the upper end of the collar. For this purpose, the stopper 24 on the base 18 is released, rotated 90 degrees horizontally counterclockwise again to return, and fixed by the stopper 24.

First, the collar side overlapping surface is measured. Release the positioning lever 68 of the portal 50 and release the positioning bar.
Switch so that another side of 52 faces upward.

In the case of this embodiment, a positioning hole 56 for measuring the collar side overlapping surface, the crosspiece lower end and the collar side upper end is provided on this surface.

The portal 50 is moved to the positioning hole 56 indicating the position where the collar side overlapping surface is measured, and the positioning lever 68 is moved.
To fix the portal 50.

The main measuring unit 78 is moved to the vicinity of the tail side of the overlapping surface on the collar side, and the roller 136 of the tracing stylus 128 provided at the lower end of the main measuring unit 78 is brought into contact with the surface of the tile W. After the contact, the measurement switch 144 is operated, and then the main measuring section 78 is run with the roller 136 contacted toward the head.
