[Effect of idea]

As described above, the present invention provides a ceramic material fixing table a having a rectangular storage and fixing recess 3 for storing and fixing a plurality of rectangular plate-shaped ceramic materials 2 in a stacked manner, and surrounds this storage and fixing recess 3. A sliding wall 4 that slides on at least two adjacent walls 4 among the four surrounding walls 4, at least one in front and one in the left and right directions.
b, and a pressing body 22 for sliding this sliding wall 4b is provided near the sliding wall 4b, and a grid-shaped cutter guide groove in the vertical and horizontal directions is formed in the bottom surface 3a of the storage fixing recess 3 and extends to the surrounding wall 4. 5, the ceramic material fixing base a is fixed on a workpiece mounting base 7 which is slidably provided in the front-rear direction and the left-right direction, and the ceramic material fixing base a is fixed on the workpiece mounting base 7 provided so as to be slidable in the front-rear direction and the left-right direction. A vertical cutting cutter member b in which cutters 9 are arranged in parallel in accordance with the longitudinal groove spacing of the cutter guide groove 5 is provided so as to be able to rise and fall freely, and the cutter 9 is guided in the axial direction of the rotary shaft 8 on the left or right side of the workpiece mounting table 7. Horizontal cutting cutter members c are arranged in parallel according to the horizontal groove spacing of the grooves 5, and the holding plate 10 that holds the uppermost plate-shaped ceramic material 2 which is stored and fixed on the ceramic material fixing table a is vertically cut by cutting cutter members b and transverse cutting cutter members c. Part c
The ceramic material fixing table a is installed in a horizontal state.
When a plurality of plate-shaped ceramic materials 2 are stacked and stored and fixed in the storing and fixing recess 3 at a time, and the workpiece mounting table 7 is slid in the front and back direction, the plate-shaped ceramic materials 2 are removed by the vertical cutting cutter member b. is cut into a predetermined width to produce a plurality of narrow ceramic plates 2a.In this state, when the workpiece mounting table 7 is returned to its original position and then slid in the left and right direction, the narrow width ceramic plate 2a is cut with the cross cutter member c. A plurality of rectangular ceramic plates 2b are completed by cutting the plate 2a into a predetermined width.

In this case, the cutters 9 of the vertical cutter member b and the horizontal cutter member c cut while moving using the cutter guide grooves 5 formed in the bottom surface 3a of the housing and fixing recess 3 of the ceramic material fixing base a and the surrounding wall 4 as guides. Since the cutter 9 does not vibrate, the plate-shaped ceramic material 2 is cut with an accurate width.
can be cut vertically and horizontally, making it possible to mass-produce rectangular ceramic plates 2b with high precision.

In this case, if the narrow ceramic board 2a is used,
Since a gap is created between the narrow ceramic plates by the blade thickness of the cutter 9, if the narrow width ceramic plate 2a is not pressed sufficiently, the narrow width ceramic plate 2a is crossed and cut by the cutter member c to form a rectangular ceramic plate 2b. When cutting, the rectangular ceramic plate 2b receives cutting resistance from the cutter 9, causing it to fall apart and scattering around, and also moving by the blade thickness gap, making it impossible to cut accurately. .

In this respect, in this proposal, since at least two of the surrounding walls 4 that are adjacent to each other are provided so as to slide, the narrow ceramic board produced after cutting the plate-shaped ceramic material 2 into the narrow ceramic board 2a. 2a
The gap between them can be eliminated by moving the surrounding wall 4, and since the uppermost narrow ceramic board 2a is held down by the holding plate 10 while being cut, even if it receives cutting resistance from the cutter 9, the narrow width ceramic board 2a is cut. Ceramic board 2
Since a does not move, it can be cut accurately, and the thin ceramic board 2a is cut into thin pieces.
Since they are pressed from above by the pressing plate 10, they do not scatter, and they can be cut into highly accurate rectangular ceramic plates 2b of the same size while being neatly arranged vertically and horizontally.

Further, in the present invention, since two of the four surrounding walls 4 slide, even if the size of the plate-shaped ceramic material 2 changes somewhat, it is possible to securely fit it into the storage fixing recess 3. .

As described above, the present invention has excellent practical effects such as being able to cut a plurality of rectangular ceramic plates 2b into the same size vertically and horizontally at the same time, greatly improving work efficiency and reducing product costs accordingly. It has the following.
