Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an apparatus for supplying a surface concrete material into a formwork of a block type block machine.

[0002]

[Prior art]

 In the immediate removal type bottom-drawing block machine, first, the base material is supplied into the formwork, the upper surface is pressed to the extent that it can be indented, and the surface concrete material is supplied on the upper surface and molded. Form a block. In the washing-out, a cement block is applied to the surface concrete material, dried and then the surface is washed with water to obtain a decorative block. This method is performed by a hydraulic press, but is inefficient and costly.

[0003] Contrary to the above, a cement setting retarder is applied to the bottom surface in a mold, a surface layer concrete material as a decorative material is supplied thereon, and a base material layer is further supplied thereon and molded. Although there is a method, it is necessary to first uniformly add the surface concrete material to the form with a thickness of 1/3 to 1/5, and this is difficult with the conventional supply box format. You. In other words, it is necessary to make the surface layer thick to some extent so that the base layer does not protrude into the surface layer, but the surface layer concrete material is relatively expensive, which increases the cost.

[0004]

[Problems to be solved by the invention]

 In the present invention, it is possible to reduce the cost by enabling the surface concrete material to be uniformly supplied to the lower part of the formwork, making it possible to reduce the thickness of the surface layer, and to reduce the cost. The surface layer of the molded block is kept to a certain degree of humidity, and if this is inverted and washed with water, a beautiful product can be obtained.

[0005]

Means for Solving the Problems According to the present invention, a feed box of a surface layer concrete material to be fed to a bottom portion of a mold is reciprocally slid on the mold in a bottom-type block machine. The inside of the supply box is divided by a partition plate into a passing portion and a non-passing portion of the surface concrete material, and a water wheel-shaped rotating body and a drop adjusting plate are arranged in the passing portion so that the flow rate of the surface concrete material can be adjusted. It is a material supply device for surface concrete characterized by the following.

[0006] That is, in the present invention, by adopting the above-described structure, the surface concrete material to be fed can be adjusted by a water wheel-shaped rotating body and a drop adjusting plate so that the falling amount thereof is adjusted as the feeding box moves. Thus, the material can be evenly and uniformly supplied to the bottom of the form. This is smoothed with a light press and vibration, and after the base concrete material is supplied on top of it, it is molded with a press and vibration. After molding, the surface is washed out to make the product smooth.

[0007]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing the main configuration of the present invention. A surface material box 1 slides on a form 6 by moving a cylinder 5 forward and backward. A partition plate 2 is disposed in the surface material supply box 1 with a slight inclination from one side to the other, and a surface concrete material 4 to be supplied into the formwork 6 slides thereon, and the partition plate 2 It falls down from between 2 and the box wall. A rotating body 3 having a windmill-like blade 7 and a flow control pipe 8 is disposed below the material dropping section, and the rotation of the rotating body 3 is adjusted between the rotating body 3 and a drop adjusting plate 9 to adjust the supply amount. And the surface concrete material 4 is supplied to the bottom of the formwork 6.

FIG. 2 to FIG. 5 are explanatory views of a process of manufacturing a decorative concrete block using the surface concrete feeding device of the present invention. In FIG. 2, reference numeral 6 denotes a formwork from which the surface material supply box 1 is projected from the upper left side by the action of the cylinder 5, and the base layer is supplied by the cylinder 11 from the right side. The material box 10 is projected. A pallet 12 is applied to the lower surface of the mold 6. A pallet 12 is provided with a cement setting retarder in advance.

FIG. 3 shows that the surface material supply box 1 is extruded onto the form 6 by the cylinder 5, and the surface concrete material 4 is supplied to the bottom of the form 6 from the space between the drop adjusting plate 9 and the rotating body 3 by the rotation of the rotating body 3. You. The supplied surface concrete material 4 is lightly pressed by a press device 13 as shown in FIG.

Next, as shown in FIG. 5, the surface material supply box 1 is retracted from the formwork, and the base material supply box 10 is projected from the right side onto the formwork 6 by the action of the cylinder 11 to form the mold. The substrate material 14 is supplied into the inside 6. It is molded by pressurizing it with a vibration by a press device 13, and is released in a down-drawing manner.

Thereafter, the pallet 12 is dried to separate the pallet 12, thereby obtaining a product shown in FIG. When this is reversed and washed with water, uncured cement is removed from the surface due to the effect of the cement setting retarder previously placed on the pallet, and this is removed, yielding a product with beautifully exposed decorative stones. FIG. 7 shows the appearance.

[0012]

[Effect of the invention]

 According to the present invention, it is now possible to mass-produce decorative concrete blocks with beautiful surfaces, which were difficult to mass-produce with a bottom-drawing, immediate-removal-type block machine, and its appearance is not inferior to conventional hydraulic press-type products. It will be. Therefore, non-defective products can be manufactured at a reduced cost.
