By the way, when producing a plate-shaped molded product such as a tile by firing a plate made of clay, firing the plate in a self-supporting state, compared with the case where the plate is laid flat. It is generally known that the combustion efficiency and loading efficiency can be improved. However, in the technique described in Patent Document 1, the upper and lower edges of the outer wall material cannot be fired in a self-supporting state so that the plate material formed of clay can be engaged with each other. There was a problem.
The present invention has been devised to solve the above problems. That is, the problem to be solved by the present invention is that the above-mentioned plate material is self-supported by providing an auxiliary leg that can be removed at a position corresponding to the concave portion of the plate-shaped molded product fired from this plate material. It is to improve the efficiency of manufacturing a plate-shaped molded product so that it can be fired in a state.

In order to solve the above-mentioned problems, the plate-shaped molded product manufacturing method and plate material molding apparatus of the present invention take the following means.
First, the first invention is a method for manufacturing a plate-shaped molded product, in which a viscous material is molded and baked to produce a plate-shaped molded product having unevenness that can be engaged with each other at a pair of opposing edges. It is. This plate-shaped molded product manufacturing method allows the main body to be self-supporting on the main body having a shape corresponding to the plate-shaped molded product by extruding the viscous material from the die of the plate material forming apparatus and cutting it at a predetermined length. A first procedure for forming a plate material having a shape to which auxiliary legs are added, a second procedure for firing the plate material in a state where the main body portion is self-supported by the auxiliary leg, and the main body portion is self-supported, and And a third procedure for removing the auxiliary legs from the plate material and processing the plate material into a plate-like molded product. In the first procedure, the main body part is formed in a shape in which both end edges along the extrusion direction of the viscous material from the base correspond to one set of edges of the plate-shaped molded product, and the auxiliary leg is the main body. Of the both end edges of the part, the concave part of the main body part corresponding to the concave and convex parts of the plate-shaped molded product is added at a position where the concave part is to be disposed.
According to the first invention, the plate material is fired in a state in which the main body portion is made self-supporting in the second procedure by forming the plate material in a shape in which the auxiliary leg is added to the main body portion in the first procedure, Combustion efficiency and loading efficiency at the time of firing can be improved. Moreover, the plate-shaped molded product of a desired shape can be manufactured from the baked board | plate material by the 3rd procedure which removes an auxiliary leg from the baked board | plate material. In addition, since the plate material is formed by extruding the viscous material from the die of the plate material forming device and cutting it, the shape of the plate material corresponds to the plate-shaped molded product with irregularities, and the main body portion is added Although it is more complicated with the auxiliary legs, the plate material can be easily formed. Further, in the plate material, by adding an auxiliary leg to a position where a concave portion corresponding to the depression of the plate-shaped molded product is to be disposed, this space is utilized for the auxiliary leg while utilizing the space necessary for the concave portion. The independent legs of the plate material can be realized by the auxiliary legs.

Next, the second invention is the above-described first invention, wherein in the first procedure, the viscous material is extruded from the die by rotation of a screw provided in the plate material forming apparatus, and in the third procedure, the plate material These auxiliary legs are removed from the main body of the plate material by an impact force applied in a direction parallel to the pushing direction of the viscous material.
The inventor, when firing a plate material formed by extruding a viscous body from a base by rotating a screw, easily breaks in an impact force in a direction parallel to the extrusion direction of the viscous body, and an impact force in a direction perpendicular to this direction. The inventors have found that a plate material that is difficult to break can be obtained, and have reached the present invention. That is, according to the second invention, the viscous material is extruded by rotating the screw in the first procedure to form the plate material, and in the third procedure, the auxiliary leg of the plate material is parallel to the extrusion direction of the viscous material. The workability of the work of removing the auxiliary leg can be improved by applying the impact force and breaking the auxiliary leg.

Furthermore, the third invention is the first or second invention described above, wherein in the first procedure, the plate material is formed with a hollow structure that opens at the surface of the plate material, and in the second procedure, the plate material A support member for assisting independence of the main body of the plate material is engaged with the hollow structure.
If another member is in contact with the viscous body when the viscous body is baked, uneven color of the baked color occurs at the contact portion. Here, according to the fifth aspect, the support member supports the self-supporting of the main body portion of the plate material, so that the main body portion of the plate material is more stably self-supported in the second procedure, and the main body portion falls down. Thus, it is possible to suppress the deterioration of the yield due to the cracking of the plate material. In addition, since the support member is engaged with the hollow structure opened on the surface of the plate material, the contact portion between the support member and the plate material that generates the uneven color of the fired color can be positioned in the hollow structure of the plate material. . Thereby, the uneven color of the baked color is placed in the hollow structure of the plate material so that it is not noticeable, and deterioration of the appearance of the plate-like molded product manufactured by processing from the plate material can be suppressed.

Furthermore, in a fourth invention according to any one of the first to third inventions described above, in the first procedure, the auxiliary leg of the plate material protrudes in the plate thickness direction of the main body portion with respect to the main body portion of the plate material. It is molded so that it does not.
According to the fourth aspect of the invention, the space required in the plate thickness direction of the plate material can be further reduced. For this reason, in the 2nd procedure of baking a board | plate material in the state which made the main-body part of the board | plate material self-supported, the loading efficiency of a board | plate material can be improved.

Further, the fifth invention is the above-described fourth invention, wherein in the first procedure, the auxiliary leg of the plate material is molded so as to be flush with the plate surface on one side of the main body portion of the plate material, and The self-supporting of the plate material is supported by sharing and supporting the weight of the plate material between the edge of the main body portion that extends flush with the other plate surface of the main body portion on the opposite side of the plate surface. It is shaped to make it possible.
According to the fifth aspect of the present invention, the space between the auxiliary leg of the plate material supporting the weight of the plate material and supporting it is possible while the space in the plate thickness direction of the plate material is restricted. Can be as wide as possible. Thereby, in the 2nd procedure which bakes a board | plate material in the state which made the main body part self-supporting, the effect which improves the loading efficiency of a board | plate material, and the effect which makes a main body part stand more stably can be acquired simultaneously.

Furthermore, a sixth invention is a plate material forming apparatus for forming a plate material to be fired for manufacturing a plate-shaped molded product by extruding a viscous body from a die and cutting it at a predetermined length. The base includes an upper and lower top dies fixed with a predetermined gap between the upper and lower sides, and a side die arranged so as to close both sides of the gap to form one passage. At least one of the side dies is formed of a partition blade portion provided along the extrusion direction of the viscous body, and the main passage portion for forming the one passage into a main body portion having a shape corresponding to a plate-shaped molded product. And a sub-passage portion that is formed in a shape corresponding to an auxiliary leg that allows the main body portion to be self-supporting and that communicates with the main passage portion in a direction perpendicular to the pushing direction of the viscous material.
According to the sixth aspect of the invention, the plate material forming apparatus pushes the viscous body through the main passage portion for forming the main body portion having a shape corresponding to the plate-shaped molded product. For this reason, even if the extrusion shape of the plate material is complicated, it is possible to easily cope with the change in the shape of the plate-shaped molded product by changing the shape of the main passage portion. The main passage portion communicates with the auxiliary passage portion in a direction perpendicular to the direction in which the viscous material is pushed out, and the auxiliary passage portion is formed in a shape corresponding to an auxiliary leg that allows the plate material to stand on its own. For this reason, a board | plate material can be shape | molded in the shape which added the said auxiliary leg to the place which should become a recessed part of this board | plate material. Thereby, in manufacture of a plate-shaped molded product, a board | plate material can be baked in the state which made the main-body part self-supported, and the combustion efficiency and loading efficiency in the case of this baking can be improved.

Yes. The plate material C formed by the plate material forming apparatus 1 is dried and then fired and finally processed into a housing outer wall material B (see FIG. 8). The outer wall material B corresponds to the “plate-shaped molded product” in the present invention.
As shown in FIG. 8, the outer wall material B is formed in a flat plate shape, and the lower end edge B1 and the upper end edge B2 are provided with irregularities B1A and B2A that can be engaged with each other via a metal fitting (not shown). It is formed into a shape. Here, the lower end edge B1 and the upper end edge B2 respectively correspond to “end edges” in the present invention.

As shown in FIGS. 2 and 3, the base 10 is fixed to the base 15 connected to the above-described extrusion portion 1 </ b> A (see FIG. 2), and passes through one passage 13 of the viscous body V. Upper and lower top dies 11 and left and right side dies 12 to be formed are provided. An opening 15A is formed in the base metal 15 corresponding to the passage 13. The opening of the opening 15 A includes the opening of the passage 13 and has an opening area larger than the passage 13. .
Further, to the base metal 15, columns 14 </ b> B extending from the position corresponding to the left and right side dies 12 to the upstream side (right side in FIG. 2) when viewed in the pushing direction of the viscous body V are fixed. Each ball 14 </ b> B is attached with a center ball 14 provided with a rod-like portion 14 </ b> A for forming a hollow structure C <b> 1 </ b> C (see FIG. 5) opened on the surface of the plate material C.

As shown in FIG. 3, split blades 12A and 12B are detachably attached to the left and right side dies 12, respectively, so as to follow the extrusion direction of the viscous body V (the direction perpendicular to the paper surface in FIG. 3). Yes. The dividing blade 12A is formed as a ring, and divides the dividing passage portion 13D from the passage 13 described above. The divided blade 12B is formed as a ring having a partition blade portion 12C, and divides the divided passage portion 13C from the passage 13. The partition blade portion 12C partitions the sub-passage portion 13B from the passage 13 by protruding outward from the ring of the divided blade 12B.
In the passage 13, the divided passage portions 13D and 13C are divided by the divided blades 12A and 12B, and the sub passage portion 13B is partitioned by the partition blade portion 12C, so that the main body C1 having a shape corresponding to the outer wall material B is obtained. A main passage portion 13A for forming (see FIG. 5) is formed.
Note that the viscous body recovery unit prevents the viscous body V pushed out through the divided passage portions 13D and 13C from coming into contact with the viscous body V pushed out through the main passage portion 13A and the auxiliary passage portion 13B. It is collected in (not shown) and re-introduced into the inlet 1A1 (see FIG. 2) of the extruding portion 1A.

According to the said structure, the board | plate material shaping | molding apparatus 1 pushes out the viscous body V through the main channel | path part 13A for shape | molding the main-body part C1 of the shape corresponding to the outer wall material B (refer FIG. 8) provided with unevenness | corrugation B1A, B2A. . For this reason, although the extrusion shape of the board | plate material C becomes complicated by the said main-body part C1 and the auxiliary leg C2 mentioned later (refer FIG. 5), the board | plate material C can be shape | molded easily.
In addition, since the main passage portion 13A is formed by dividing one passage 13 by the divided blades 12A and 12B and partitioning by the partition blade portion 12C, the shape of the main passage portion 13A can be changed by replacing the divided blades 12A and 12B. Can be changed. For this reason, even when the extrusion shape (refer FIG. 5) of the outer wall material B is complicated, it can respond easily to the change of the shape of the outer wall material B. FIG.

Here, as shown in FIG. 4, the sub-passage portion 12B is perpendicular to the pushing-out direction of the viscous body V with respect to the main passage portion 13A described above (in this embodiment, the width direction of the main passage portion 13A). Communication is made in the left-right direction as viewed in FIG. For this reason, the board | plate material C extruded from the nozzle | cap | die 10, and is cut | disconnected by the cutting part 1C and shape | molded corresponds to the outer wall material B by being extruded through the main channel | path part 13A, as shown in FIG. It becomes the shape which added the auxiliary leg C2 which enables self-support of the board | plate material C (refer FIG. 6) in the place which should become the recessed part of the main-body part C1 formed in the shape.
Moreover, as shown in FIG. 4, the front-end | tip of the partition blade part 12C is bent toward the top die 11 on the upper side in the drawing. The upper top die 11 has a grooving blade 11A for forming a groove C2A in the plate material C along the boundary between the auxiliary leg C2 and the main body C1 so as to face the tip of the partition blade 12C. It is detachably bolted. As a result, as shown in FIGS. 5 to 8, the boundary between the auxiliary leg C2 and the main body C1 in the plate member C can be clearly seen by the groove C2A, and the boundary between the auxiliary leg C2 and the main body C1. Becomes brittle due to the groove C2A. Further, since the grooving blade 11A is detachable, the shape of the groove C2A can be changed by replacing the grooving blade 11A.

Next, a method for manufacturing the plate-shaped molded product according to the first embodiment (that is, the outer wall material B shown in FIG. 8) will be described mainly with reference to FIGS. In addition, in the following, illustration and detailed description of an incidental procedure such as a procedure for drying the formed plate material C (see FIG. 5) and a procedure for firing the plate material C are omitted.
In the manufacturing method of the outer wall material B, first, as shown in FIG. 1, the viscous material V (clay) is extruded from the base 10 using the plate material forming apparatus 1 described above, and cut by the cutting portion 1C to a predetermined length. Thus, the plate material C is formed. The step of forming the plate material C corresponds to the “first procedure” in the present invention.

As shown in FIGS. 5 to 7, the plate material C formed as described above is formed with a through-hole-shaped hollow structure C <b> 1 </ b> C that is open on both facets of the plate material C. The hollow structure C1C extends over the entire length of the plate member C in a direction parallel to the extrusion direction of the viscous body V (left and right direction as viewed in FIG. 7).
In the present embodiment, as shown in FIG. 5, the plate member C has an upper edge C1A having an unevenness corresponding to the unevenness B1A of the lower edge B1 of the outer wall material B on one side (the left side in the drawing). Is formed. In addition, at the edge of the other side (right side in the figure) of the plate material C, there is a lower end edge C1B formed in a shape corresponding to the protruding portion of the unevenness B2A of the upper end edge B2 of the outer wall material B, and An auxiliary leg C2 is formed at a position where a corresponding recess is to be disposed.

In addition, the board | plate material C replaces each division | segmentation blade 12A, 12B (refer FIG. 3) in the right and left side die 12 of the board | plate material shaping | molding apparatus 1, and as shown in FIG. It can be formed in a shape corresponding to the upper edge B2. In this case, the lower end edge C1B of the plate material C is formed in a shape corresponding to the protruding portion of the unevenness B1A of the lower end edge B1 of the outer wall material B, and the auxiliary leg C2 of the plate material C is a recess corresponding to the recess in the unevenness B1A. Is added to the position to be disposed.
In each said structure, the auxiliary leg C2 is added to the position where the recessed part of the board | plate material C should be arrange | positioned. Thereby, the auxiliary leg C2 can be added using the space for making the said recessed part in the board | plate material C. FIG.

In each of the plate members C, the lower end edge C1B and the auxiliary leg C2 face each other, and the amount of protrusion in the plate width direction (left-right direction as viewed in FIG. 5 and up-down direction as viewed in FIG. 11) is almost equal. It is set to be equal.
Further, the auxiliary leg C2 of the plate material C is formed so as not to protrude in the plate thickness direction (left and right direction as viewed in FIG. 6) of the main body portion C1 with respect to the main body portion C1 of the plate material C. Furthermore, the auxiliary leg C2 is flush with one side plate surface (the right side plate surface in FIG. 6) of the main body C1, and the lower edge C1B is the other side plate of the main body C1. It is flush with the surface (left plate surface as viewed in FIG. 6).

As shown in FIG. 6, the plate member C formed through the first procedure described above is dried so that the main body C1 is self-supported by the auxiliary legs C2 on the flat mounting surface S1 of the baking shelf S. Are fired in this state. By arranging and firing the main body C1 of the plate material C so as to be self-supporting by the auxiliary legs C2, it is possible to improve the combustion efficiency and the loading efficiency during the firing. The step of firing the plate material C in a state where the main body C1 is self-supporting corresponds to the “second procedure” in the present invention.
Here, the plate material C is necessary in the plate thickness direction of the main body portion C1 by preventing the auxiliary legs C2 from protruding in the plate thickness direction (the left-right direction in the drawing) of the main body portion C1 relative to the main body portion C1 of the plate material C. Space is narrowed. Thereby, the effect which improves the loading efficiency of the board | plate material C in the case of the said baking can be improved.

As shown in FIG. 6, the auxiliary leg C <b> 2 is added to the main body C <b> 1 of the plate material C, thereby enabling the main body C <b> 1 to be independent. That is, the main body portion C1 of the plate material C shares and supports its own weight at the two positions of the lower end edge portion C1B and the auxiliary leg C2 of the plate material C, thereby maintaining the balance on the mounting surface S1 of the baking shelf S. You can become independent.
Here, the plate material C has the auxiliary leg C2 flush with the plate surface on one side (right side in the figure), and the lower edge C1B is flush with the plate surface on the other side (left side in the figure). While preventing the lower end edge C1B and the auxiliary leg C2 from protruding from each plate surface of the plate material C, the gap between the lower end edge C1B and the auxiliary leg C2 is ensured as wide as possible. Thereby, at the time of baking of the board | plate material C mentioned above, the effect which improves the loading efficiency of this board | plate material C, and the effect which makes the main-body part C1 of the board | plate material C stand more stably can be acquired simultaneously.

When acceleration such as vibration is applied to the baking shelf S and the plate material C arranged on the mounting surface S1 of the baking shelf S is assumed to fall down, it is supported by the hollow structure C1C of the plate material C. The member S2 can be engaged to assist the self-supporting of the main body C1 of the plate material C. That is, as shown in FIG. 7, a support column S21 is provided to face the opening of the hollow structure C1C of the plate material C arranged on the baking shelf S, and the support member S2 attached to the support column S21 is attached to the hollow structure C1C of the plate material C. Can be inserted and engaged.
According to the above configuration, the support member S2 assists the self-supporting of the main body C1 of the plate material C, so that the main body C1 of the plate C can be more stably self-supported, the main body C1 falls down and the plate material C breaks. The deterioration of the yield due to this can be suppressed. Further, by engaging the support member S2 with the hollow structure C1C opened in the plate material C, a contact portion between the support member S2 and the plate material C that generates uneven color of the firing color at the time of firing is formed in the hollow of the plate material C. It can be located in structure C1C. Thereby, the uneven color of the baked color is placed in the hollow structure C1C of the plate material C so as to be inconspicuous, and deterioration of the appearance of the outer wall material B processed and manufactured from the plate material C can be suppressed.

The plate material C fired as described above is processed into the outer wall material B by removing the auxiliary legs C2 from the main body C1, as shown in FIG. Thereby, the outer wall material B of a desired shape can be processed and manufactured from the plate material C. The process of manufacturing the outer wall material B from the plate material C corresponds to the “third procedure” in the present invention.
The removal of the auxiliary leg C2 in the third procedure is performed by cracking using the hammer H and the chisel H1. That is, the plate material C fired in the second procedure is first oriented in the direction parallel to the extrusion direction of the viscous body V in the plate material C along the boundary between the auxiliary leg C2 and the main body C1 (rightward in FIG. 8). ) Hagane's blade is assigned. Next, by applying an impact force in the direction of the blade of the chisel H1 (rightward in FIG. 8) to the chisel H1 by the hammer H, the auxiliary leg C2 is cut off from the main body C1, and the outer wall material B is cut. Processed. By removing the auxiliary leg C2 by cutting, the workability of the work of removing the auxiliary leg C2 can be improved.

Here, as shown in FIGS. 5 to 8, a groove C2A is formed in the plate C described above along the boundary between the auxiliary leg C2 and the main body C1. As a result, the position and direction to which the blade of the chisel H1 is applied can be clearly understood, and the boundary portion between the auxiliary leg C2 and the main body C1 becomes weak, so the auxiliary leg C2 is cut off and removed. The workability of the work to be performed can be improved.
The direction of the impact force from the chisel H1 and the hammer H described above is set to any direction as long as it is a direction parallel to the pushing direction of the viscous body V in the plate material C (left-right direction in FIG. 8). Even if it is done, the auxiliary leg C2 can be cut off smoothly. On the other hand, when the direction of the impact force from the chisel H1 and the hammer H is set in a direction perpendicular to the pushing direction of the viscous body V, the auxiliary leg C2 cannot be cut off well. This is because when the viscous material V is extruded from the base 10 by the rotation of the screw 1A2 (see FIG. 2) to form the plate material C in the first procedure described above, a concentric cylindrical layer is formed on the plate material C. This is considered to be because the fired plate material C is easily broken along the concentric cylindrical layer.

Then, the manufacturing method of the plate-shaped molded product which concerns on 2nd Embodiment is demonstrated using FIG. 9 and FIG. The manufacturing method of the plate-shaped molded product according to the second embodiment is an embodiment in which only the third procedure is changed in the manufacturing method of the plate-shaped molded product according to the first embodiment. Accordingly, the same reference numerals as those in the method for manufacturing the plate-shaped molded product according to the first embodiment are assigned to the components common to the components in the method for manufacturing the plate-shaped molded product according to the first embodiment. Therefore, detailed description thereof is omitted.
The manufacturing method of the plate-shaped molded product according to the second embodiment includes cutting in the third procedure in which the auxiliary leg C2 is removed from the plate material C fired in the second procedure and the plate material C is processed into the outer wall material B. The auxiliary leg C2 is cut and removed from the main body C1 of the plate material C using the device D. In addition, in the following, illustration and description of the incidental members such as the electric wiring of the cutting device D are omitted.

The cutting device D includes a chain conveyor D3 that conveys the fired plate material C in a certain direction (rightward as viewed in FIG. 9), and a disk-shaped diamond blade that is arranged in parallel with the conveying direction of the chain conveyor D3. D1 and D2.
As shown in FIG. 10, the diamond blade D1 is arranged on the upper right side (upper right side in the figure) as viewed from the direction of conveyance of the chain conveyor D3, and from above the plate material C conveyed by the chain conveyor D3. It has come to hit. The diamond blade D2 is arranged on the lower left side (lower left side in the figure) when viewed from the direction of conveyance of the chain conveyor D3, and comes into contact with the plate material C conveyed by the chain conveyor D3 from below. ing.

The diamond blades D1 and D2 are attached to the rotation shafts of the motors D11 and D21, and are rotated by the motors D11 and D21, so that the plate material C of the portion that the diamond blades D1 and D2 hit is cut. It has become.
Here, the motors D11 and D21 are respectively attached to sliders D12 and D22 that are slidable in the vertical and horizontal directions as seen in FIG. Therefore, by sliding the sliders D12 and D22 together with the motors D11 and D21 and the diamond blades D1 and D2, the positions of the diamond blades D1 and D2 can be adjusted to adjust the cutting position of the plate material C. It is like that.

When the auxiliary leg C2 is removed from the plate material C by the cutting device D described above, first, the plate material C is placed on the upstream portion of conveyance in the chain conveyor D3, and the arrangement of the plate material C and each diamond blade D1, D2 is arranged. Adjust.
The plate C has an upper edge C1A on the left side (left side as viewed in FIG. 10) as viewed from the direction of conveyance, and an auxiliary leg C2 on the right side and upper side (as viewed in FIG. 10) as viewed from the direction of conveyance. It is arranged to be on the right side and the upper side. The diamond blade D2 is disposed at a position where the plate material C hits the end surface of the upper edge C1A when the plate material C is conveyed by the chain conveyor D3. The diamond blade D1 is disposed at a position corresponding to the boundary between the auxiliary leg C2 and the main body C1 in the plate material C when the plate material C is conveyed by the chain conveyor D3. Here, since the groove C2A is formed at the boundary between the auxiliary leg C2 and the main body C1, it is possible to clearly identify the boundary and arrange the diamond blade D1.

Next, the motors D11 and D12 and the chain conveyor D3 of the cutting device D are driven to cut and remove the auxiliary legs C2 from the plate material C, and the end surface of the upper edge C1A of the plate material C is cut, thereby removing the plate material. C is processed into an outer wall material B.
That is, the above-described diamond blade D1 is rotated by the motor D11 and hits the boundary portion between the auxiliary leg C2 and the main body C1 in the plate material C conveyed by the chain conveyor D3. The main body C1 is separated. Moreover, the diamond blade D2 mentioned above cuts this end surface by hitting the end surface of the upper edge C1A of the board | plate material C conveyed by the said chain conveyor D3 in the state rotated by the said motor D21.

Here, the diamond blade D1 is applied from the upper side of the plate material C as shown in FIG. For this reason, the cutting device D can separate the auxiliary leg C2 without cutting the lower end edge C1B of the main body C1. Further, the separated auxiliary leg C2 does not fall and hit the motor D11.
Moreover, as shown in FIG. 9, each diamond blade D1 and D2 is arrange | positioned so that it may become in parallel with the conveyance direction of the chain conveyor D3 mentioned above, respectively. Thereby, in the outer wall material B manufactured by processing the plate material C with the cutting device D, planar cut edges parallel to each other can be formed on the lower end edge B1 side and the upper end edge B2 side. Here, by forming each cut end of the outer wall material B after firing the plate material C, deformation of the plate material C caused by the firing when firing the plate material C formed from the viscous material V from each cut end. The influence of can be eliminated.

For example, the following various forms can be implemented.
(1) In FIG. 7, the support member S2 is inserted into and engaged with the hollow structure C1C of the plate material C from both left and right sides of the drawing. However, the configuration in which the support member S2 is engaged with the hollow structure C1C of the plate material C is not limited to this. That is, for example, a configuration in which the support member S2 is inserted into and engaged with the hollow structure C1C of the plate material C only from one side can be used. Further, for example, a configuration in which the support member S2 is a long member such as a rod, string, chain, or the like, and the support member S2 is inserted into the hollow structure C1C of the plate material C and engaged can be used.
(2) The hollow structure of the plate material with which the support member is engaged is not limited to a through-hole shape that is open on both small edge surfaces of the plate material. That is, for example, a movable grooving blade is provided in a plate material forming apparatus, and a groove that is partially deepened is formed in the plate material being formed by the grooving blade, whereby a support member is provided in a deepened portion of the groove. A configuration to be engaged can be used.
(3) The supporting member that assists the self-supporting of the main body of the plate material is not limited to that engaged with the hollow structure of the plate material. That is, by engaging the support member with a portion that is not exposed to the outside when the outer wall material is used, such as a dent formed on the upper edge or the lower edge of the plate material, the uneven color of the fired color is made inconspicuous. It can suppress that the appearance of the outer wall material manufactured by processing from a plate material deteriorates. Further, the support member is manufactured by being processed from the plate material, for example, by engaging with a portion of the plate material which is removed after firing the plate material, such as an auxiliary leg of the plate material and an end surface of the upper edge of the plate material (see FIG. 10). The influence of uneven color of the fired color can be eliminated in the outer wall material.
(4) The method of removing the auxiliary legs from the plate material in the third procedure is not limited to the above embodiments. That is, the auxiliary legs of the plate material can be removed from the plate material using any method such as cutting with a cutting grindstone or cutting with a grinder.
(5) The plate-like molded product to which the present invention can be applied is not limited to a housing outer wall material. That is, the method for manufacturing a plate-shaped molded article according to the present invention is an arbitrary one having a pair of concavities and convexities that can be engaged with each other, such as a ceramic plate tile used in a house roof or indoors. It can be used when producing a plate-shaped molded article by firing a viscous body.
(6) As a viscous material that is a raw material for a plate-shaped molded product, any viscous material that can be molded and fired, such as a kneaded ceramic powder or a fine ceramic raw material powder, can be used.
