The press die 14 is moved up and down by an expansion / contraction operation of a cylinder rod of a hydraulic cylinder device (not shown).
[Production method]
Next, the manufacturing method of the design block manufacturing apparatus 10 configured as in the above embodiment will be described.

  First, as shown in FIG. 1, the base layer material supply box 108 is positioned directly below the hopper HP (second position), and the base layer material Wa is supplied to the base layer material supply box 108 from the hopper HP.

  In addition, the surface layer material supply box 11 is positioned directly below the hopper 13 (third position), and the surface layer material Wb is supplied from the hopper 13 to the surface layer material supply box 11. Further, the pallet 23 is raised to the position shown in FIG. 1 by the hydraulic cylinder device 25, and the opening 20 b of the molding mold 20 is closed by the pallet 23.

  As shown in FIG. 4, the closing plate 42 of the spreading means 40 of the aggregate supply box 30 closes the hole 41a of the punching metal 41, and the aggregates K1 and K2 are supplied to the aggregate supply box 30 by a hopper (not shown). Keep it.

  Next, as shown in FIG. 3, the base layer material supply box 108 is moved to a position above the molding frame 20 by a hydraulic cylinder device (not shown), and the base layer material Wa of the base layer material supply box 108 is moved into the molding frame 20. The base layer material Wa is filled into the molding form 20 by dropping. When the filling of the base layer material Wa into the molding mold 20 is completed, the base layer material supply box 108 is retracted to the right by the hydraulic cylinder device 12.

  Thereafter, the press die 14 is lowered from the position of the chain line shown in FIG. 6 by a hydraulic cylinder device (not shown) to press the base layer material Wa in the molding die 20. By this pressing, the base layer 60Sa of the design block 60 shown in FIG. 12 is molded.

  After this molding, the press die 14 is raised to the chain line position shown in FIG. 6, and the surface material supply box 11 is moved to a position above the molding die 20 shown in FIG. Then, the surface layer material Wb of the surface layer material supply box 11 is dropped into the mold 20 and the surface layer Wb is filled on the base layer 60Sa (see FIG. 12) in the mold 20. In this filling, the surface material supply box 11 is moved left and right as necessary so that the molding mold 20 is filled almost uniformly.

  When the filling of the surface layer material Wb into the mold 20 is completed, the surface layer material supply box 11 is retracted leftward from the position shown in FIG.

  When the surface material supply box 11 is retracted, the closing plate 42 of the dispersion means 40 of the aggregate supply box 30 is moved to the solid line position in FIG. 8 by a hydraulic cylinder device (not shown) to open the hole 41a of the punching metal 41. As a result, the aggregates K1 and K2 are discharged from the hole 41a, fall downward from the tip end portion 43a of the inclined wall 43 as indicated by the arrow P, and are scattered randomly.

  This scattering is performed while the aggregate supply box 30 moves to the left as the surface layer supply box 11 is retracted, so that the upper surface of the surface layer material Wb in the mold 20 is formed as shown in FIG. It will be scattered randomly.

  When the tip 43a of the inclined wall 43 of the spreading means 40 is located at the left end of the molding die 20, the closing plate 42 of the spreading means 40 is moved to the solid line position as shown in FIG. The aggregates K1 and K2 are stopped by dropping and the aggregates K1 and K2 are stopped from being scattered.

  When the surface material supply box 11 is retracted to the position shown in FIG. 10, the surface material Wb is supplied from the hopper 13 to the surface material supply box 11.

  On the other hand, the press die 14 is lowered by the hydraulic cylinder device (not shown) from the chain line position shown in FIG. 10 and pushes the upper surface of the surface layer material Wb in the molding die 20. At this time, the aggregates K1 and K2 scattered on the upper surface of the surface layer material Wb bite into the upper surface.

  Then, as shown by the solid line in FIG. 10, the base layer 60Sa and the surface layer material Wb are inserted into the molding mold 20 and pressed further on the surface layer material Wb on the base layer 60Sa in the molding mold 20. Press molding is performed with the frame 20 and the press die 14. As a result, a plurality of design blocks 60, 60 (see FIG. 11) in which the surface layer 60Sb is formed on the base layer 60Sa are press-molded.

  When this press molding is completed, as shown in FIG. 11, the press die 14 is raised by the hydraulic cylinder device, and the pallet 23 and the lifting table 24 are lowered by the hydraulic cylinder device 25. As the pallet 23 and the lifting table 24 are lowered, the design blocks 60, 60 are removed from the mold 20.

  As shown in FIG. 12, white aggregate K1 and black aggregate K2 are randomly scattered on the upper surface 60A (surface layer 60Sb) of the design block 60, and the aggregates K1 and K2 are pressed by the press die 14. By doing so, as shown in FIG. 13, it will bite into the upper surface 60A of the design block 60, and a part of the aggregates K1 and K2 will be exposed, so that a natural texture can be sufficiently produced, resembling natural stone. It is possible to mold the design block 60 rich in design properties.

  Further, by forming moderate irregularities (predetermined pattern: natural pattern) on the lower surface of the press die 14, the upper surface 60A (surface layer 60Sb) of the design block 60 is formed with concave portions 60a and convex portions 60b as shown in FIG. 13A. Then, the aggregates K1 and K2 are in a state where the uneven portions 60a and 60b are bitten. For this reason, even if the base layer material Wa and the surface layer material Wb are concrete materials, a texture of natural stones can be obtained. That is, a design block resembling a natural object can be molded.

  In the above embodiment, the white aggregate K1 and the black aggregate K2 are dispersed. However, either one of the aggregates may be used as long as it can produce a natural stone texture. May be. Further, only one color aggregate may be used.

  The size of the aggregates K1 and K2 is set to the size of No. 3 to 5, but may be other sizes.

  Since the aggregates K1 and K2 are dropped through the hole 41a of the punching metal 41, the amount of the aggregates K1 and K2 dispersed on the upper surface of the surface layer material Wb can be stabilized to some extent, and the variation for each manufacturing rod becomes too large. Therefore, the design properties can be stabilized, and the variations can be made moderately, so that the natural texture can provide sufficient design properties.

[Second Embodiment]
FIG. 14 shows the configuration of the design block manufacturing apparatus 100 of the second embodiment. The design block manufacturing apparatus 100 includes a base material supply box 108 (see FIG. 15A) that stores the base material Wa, a surface material supply box 110 that stores the concrete materials W1 and W2, which are surface materials, and the concrete materials W1 and W2.

[Production method]
Next, a manufacturing method of the design block manufacturing apparatus 100 configured as in the second embodiment will be briefly described.

  First, as shown in FIG. 14, the surface layer material supply box 110 is moved directly below the hopper 130 (third position), and the concrete materials W1 and W2 mixed from the hopper 130 into the respective accommodating portions 11Va of the surface layer material supply box 110 are placed. Replenish (see FIG. 15). Similarly, the base layer material supply box 108 (see FIG. 1) is moved directly below the hopper (not shown) (first position), and the base layer material Wa is supplied from the hopper.

  Further, as in the first embodiment, the pallet 23 is raised to the position shown in FIG. 14 by the hydraulic cylinder device 25, and the opening 20b of the mold 20 is closed by the pallet 23, and the aggregate supply box The aggregate K is accommodated in 30 in advance.

Next, the base layer material supply box 108 is moved to the position shown in FIG. 15A by a hydraulic cylinder device (not shown), and the base layer material Wa of the base layer material supply box 108 is dropped into the molding mold 20 to enter the molding mold 20. The base layer material Wa is filled. When this filling is completed, the base material supply box 108 is retracted.
Thereafter, the press die 14 is lowered to press the base layer material Wa in the molding die 20 (see FIG. 6).

  By this pressing, the base layer 160Sa of the design block 160 (see FIG. 19) is molded as in the first embodiment.

  After this molding, the press die 14 is raised as shown in FIG. 14, and the surface material supply box 110 is moved to a position above the molding die 20 as shown in FIG. 15B. Then, the concrete materials W1 and W2 accommodated in the surface layer material supply box 110 are dropped into the molding mold 20, and the concrete materials W1 and W2 are filled on the base layer 160Sa filled in the molding mold 20. To go.

  When the filling of the concrete materials W1 and W2 into the molding form 20 is completed, the surface layer material supply box 110 is retracted.

  When the surface material supply box 110 is retracted, the aggregate K of the aggregate supply box 30 is dispersed on the upper surfaces of the concrete materials W1 and W2 as shown in FIGS. 16 and 17, as in the first embodiment.

  Thereafter, the press die 14 is lowered by a cylinder device (not shown) and pushes the upper surfaces of the concrete materials W1 and W2 in the molding die 20 (see FIG. 10). At this time, the aggregate K scattered on the upper surfaces of the concrete materials W1 and W2 bites into the upper surfaces.

  Then, as in the first embodiment, the press die 14 is fitted into the molding die 20 and the concrete materials W1 and W2 in the molding die 20 are press-molded. As a result, a plurality of design blocks 160, 160 (see FIG. 18) in which the surface layer 160Sb is formed on the base layer 160Sa (see FIG. 19) are press-molded.

  When this press molding is completed, the press die 14 is raised by the cylinder device as shown in FIG. 18, and the pallet 23 and the lifting table 24 are lowered by the hydraulic cylinder device 25. As the pallet 23 and the lifting table 24 are lowered, the design blocks 160 and 160 are removed from the mold 20.

  On the surface layer 160Sb of the design block 160, for example, as shown in FIG. 19, a dark gray portion 160a and a light gray portion 160b are formed to give a natural stone texture, and the aggregates are formed on the portions 160a to 160c. When K is biting in, a texture of natural stone can be obtained, and the design block 160 is rich in design.

  Further, by forming moderate irregularities (predetermined pattern: natural pattern) on the lower surface of the press die 14, the upper surface 160A of the surface layer 160Sb of the design block 160 is provided with a concave portion 161 and a convex portion 162 as shown in FIG.

  Further, the surface layer material is not limited to the two color concrete materials W1 and W2, and several kinds of different color concrete materials may be used and formed on the lower surface of the press die 14 with a natural pattern such as wood grain. Then, a design block that resembles a natural object such as wood grain may be molded. It is also possible to manufacture a design block that resembles a tile with the unevenness of the lower surface of the press die 14 as a tile pattern. That is, the present invention can also be applied to architectural design blocks.

  In addition, by firing the molded design block, it can be made into a design block resembling a brick, and the aggregate K is the size of No. 3 silica sand, and the seed stone is scattered, For this reason, it becomes a design block more similar to a brick. Furthermore, by baking one of the two concrete materials W1 and W2 and molding the molded design block, a design block resembling a brick is obtained.

  By making the lower surface of the press die 14 a brick pattern, the design block can be finished in a further brick style.

  Furthermore, the firing process is performed from the gas burner by using a gas burner in which propane gas is used by mixing the oxygen oxide pigment as the main raw material with the surface layer material Wb in advance and mixing compressed oxygen as appropriate. The flame to be produced is adjusted to fire power to be an oxidation flame and a reduction flame, and the distance between the surface layer material Wb of the design block and the gas burner is adjusted and fired. By this firing, color unevenness based on the change in the hue of the iron oxide pigment can be generated in the surface layer material Wb, and the surface of the surface layer material Wb can have a color pattern equivalent to that of an actual brick.

  Details of the firing process are described in Japanese Patent No. 438695, and therefore detailed description thereof is omitted.

  Further, the aggregate K may be made into a brick-like shape by firing it as described above by using two kinds of aggregates of different colors to give a natural stone texture in the same manner as in the first embodiment. .
