According to the present invention, the concrete is cured in the manufacture of concrete boundary stones, and then cut and polished to produce a plurality of concrete boundary stones, thereby enabling efficient mass production and contributing to the dimensional accuracy of the boundary stones and expressing surface patterns. It relates to a boundary stone manufacturing apparatus.

In general, boundary stones, which are widely used in the construction field, can be divided into concrete boundary stones, artificial granite boundary stones, and granite boundary stones according to materials. Natural stone such as granite boundary stone shows excellent characteristics in durability, fire resistance, and compressive strength, but recently, it is increasingly difficult to secure high quality gemstones due to indiscriminate quarrying and protection of natural environment. to be. In line with this phenomenon, the unit price of the product is also rising.

Artificial granite boundary stone is attached to mortar layer including calcite in general concrete, and its shape is similar to granite, but there is a problem that the mortar layer is separated due to the deterioration of adhesion strength between mortar and concrete, which may cause a sudden drop in product performance. . In addition, there is a problem that mass production is difficult because one mold per product is required. This problem leads to an increase in unit price.

Concrete boundary stone is the most advantageous in terms of product cost because of low raw material cost, but there is a problem that there is a high possibility of unit price increase because it requires one molding mold per product, which makes it difficult to mass-produce. There is a problem that can not express the surface patterns such as granite boundary stone or artificial granite boundary stone in the shape of, there is a problem that the performance such as compressive strength is very poor. In addition, there is a burden that must be precisely the amount of the concrete material mixture to be put into the mold.

Therefore, the present invention is to solve the conventional problems as described above, by curing the concrete in one large forming mold of the size including a plurality of boundary stones and then cutting them to produce a plurality of boundary stones more efficiently and more accurately It is an object of the present invention to provide a concrete boundary stone manufacturing apparatus that can express the surface pattern through the cutting or polishing process at the same time manufacturing.

In the present invention, the concrete ore is taken out from the mold and has not yet undergone the cutting or polishing process, and the concrete molding is to refer to the concrete ore which has been subjected to at least one cutting or polishing process.

In order to achieve the above object, the concrete boundary stone manufacturing apparatus of the present invention,

It is possible to produce a number of concrete boundary stones expressed in the surface pattern from the raw concrete cured by one mold.

Here, the concrete material may include aggregate, cement, water and pigments. Bottom ash can be used to contribute to eco-friendliness, and the coloring allows for beautiful colors and efficient patterns.

Here, the molding frame is a rectangular shape in which the front, rear, left and right sides are blocked, and the front, rear, left and right sides can be opened and closed based on the side of the lower side. Therefore, it is easy to extract from the mold after curing concrete ore.

Here, the concrete gemstone manufacturing apparatus may further include a vibrator for compact concrete molding.

Here, the conveying device may be made of a conveying belt and a conveying vehicle.

Here, the concrete boundary stone dimensions and surface treatment apparatus may include one or more top surface carburizing machine for the top surface polishing process based on the curing process of the concrete ore.

In addition, the concrete boundary stone dimensions and surface treatment apparatus is a top and bottom converter for overturning the concrete molding polished in the top surface carbrating machine, and one or more for the top surface of the inverted concrete molding (based on the curing process of the concrete molding) The carrier may further include a carburetor.

Here, the cutter may include a terminal cutter for cutting the concrete gemstone in the longitudinal direction, a chamfering machine for chamfering the upper surface of one side of the longitudinally cut surface, and a transverse cutter for cutting the concrete gemstone in the transverse direction. By this cutting process, a number of boundary stones can be manufactured from one concrete raw material together with the expression of the surface pattern, thereby improving productivity.

The concrete boundary stone produced by the above-described concrete boundary stone manufacturing apparatus is a surface pattern that was a disadvantage of the existing concrete boundary stone is expressed.

Hereinafter, an embodiment of a concrete boundary stone manufacturing apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a side cross-sectional view showing a device for producing concrete ore. On the upper part of the left tower, a cement loading input unit 121 and a dye loading input unit 131 are installed. In the cement loading input unit 121 and the dye loading input unit 131, input devices 122 and 132 are respectively installed to discharge a fixed amount of cement and pigment. The discharged cement and the dye is added to the mixer 140. Adding color to concrete has the advantage of expressing colors that cannot be expressed in natural stone.

The small bottom ash loading and pouring portion 111, the large bottom ash loading and dropping portion 112, and the stone powder loading and dropping portion 113 are installed side by side at the right ground level. In the embodiment of the present invention, the bottom ash and stone powder is added as an example, but is not necessarily limited thereto. Stone powder may not be added or aggregates other than bottom ash may be added. In each of the loading inputs (111, 112, 113) it is provided with the input device (114, 115, 116) for injecting each material down to control the proportion of the material. The lower portion of the loading input portion (111, 112, 113) is provided with a conveying belt and a conveying vehicle 117 for transferring the material discharged through the input device to the left. The materials transported by the transport belt and the transport vehicle 117 are loaded into the transport container 118. The loading transfer container 118, into which the material is conveyed, is lifted by the rail 119 to inject the material loaded into the mixer 140.

As in the present embodiment, when cement, pigment, stone powder, etc. are adjusted to an appropriate ratio and added to the mixer 140, the mixer 140 uniformly mixes these materials with an appropriate ratio of water. The mixed concrete material is discharged by the mixture ejector 141 into the lower mold 151 by a predetermined amount. In the embodiment of the present invention, the size of the mold 151 is not limited to 210 cm x 106 cm x 46 cm (length x width x height) and dimensions.

As described above, when the concrete material mixture is filled in the mold 151 by a predetermined amount, the vibrator 153 located below the mold 151 vibrates the mold 151 so that the concrete material mixture may have a tighter structure. Let's do it. Vibration allows the concrete material mixture to be firmly located in the mold 151, but the vibration amount should be made to an appropriate level. If too much vibration is applied, separation of the concrete material mixture may occur.

In the embodiment of the present invention, the vibrator 153 is used, but other means for forming (compacting) tight concrete, for example, press molding (compacting), vibration pressing (compacting), centrifugal molding (compacting), etc. Various methods commonly used for the compact shaping (compacting) of can be used.

After the operation of the vibrator 153, the conveyance belt and the conveying vehicle 152 transfers the molding die 151 to a curing chamber (not shown). Curing takes place until the concrete ore is finished in the curing room.

Figure 2a is a perspective view showing a molding die in the concrete raw stone manufacturing apparatus of Figure 1, Figure 2b is a perspective view showing an open state of the molding die of Figure 2a. When curing is completed, the concrete raw material 4 (see FIG. 4A) is completed. A tong (not shown) as a takeout member is used to extract the finished concrete raw material 4 and transfer it to the concrete boundary stone cutting and polishing apparatus 3. First it is confirmed that the concrete curing is completed, as shown in Figure 2b opens the side of the mold 151. Then, the concrete raw material 4 is placed on the forming mold 151 (the concrete raw material 4 is not shown in FIG. 2B), and lifted it with tongs to transfer the cutting polishing device 3 (see FIG. 3). It is placed on the belt and the carriage 21 (upper right side in FIG. 3). Here, it is preferable that a shock absorber is installed on the transport belt and the transport vehicle to absorb the impact when the concrete gemstone 4 is raised. As a result, one concrete raw material 4 is introduced into the cutting polishing apparatus 3.

Figure 3 is a plan view showing a concrete boundary stone cutting and polishing apparatus according to the present invention, Figure 4a is a perspective view showing the concrete ore cured by the molding frame, Figure 4b is a top surface of the concrete ore of Figure 4a (based on the curing process of the concrete molding) 4C is a perspective view showing a state of carburizing the lower surface (based on curing process of the concrete molding) of the concrete molding of FIG. 4B, and FIG. 4D is a longitudinal cut of the concrete molding of FIG. 4C. 4E is a perspective view showing a state in which the concrete molding of FIG. 4D is chamfered, and FIG. 4F is a perspective view showing a state in which the concrete molding of FIG. 4E is cross-cut.

First, the raw concrete 4 is aligned with the upper cylinder carburetor 31 after the alignment is made by the air cylinder 23. In this case, the carburizing machine may generally be used in the stone processing industry, and may be used in the art of polishing the natural stone carburizing machine. In the exemplary embodiment of the present invention, one cup wheel 311 polishing machine having a diameter of 1200 mm is used, but the size and grain size of the polishing machine may be suited according to the state of the concrete boundary stone or concrete stone to be manufactured. The process of caribrating the upper surface by the rotation of the cup wheel 311 is shown in Figure 4b. The upper surface caribrating process is a process required for neat surface treatment because the upper surface of the concrete gemstone 4 has a large surface roughness and curvature unlike the lower surface during concrete curing. The process may be performed twice, three times, four or more times to fit the dimensions.

The concrete molding having the upper surface carburizing is reached by the transfer belt and the conveying vehicle 21 to reach the upper and lower diverters 32, and is turned over by the upper and lower diverters 32. In an embodiment of the invention a turn over roller conveyor is used. When overturning, it is desirable to equip it so that it does not have a big impact. When turned upside down, the surface polished by the upper surface caribrating machine 31 is now located at the lower portion, and the surface that was the lower surface at the time of curing is positioned at the upper portion.

The inverted concrete molding is aligned by the air cylinder 23 and then transferred to the lower surface of the carburetor 33 by the conveying belt and the conveying vehicle 21. The surface of the upper portion of the transferred concrete molding (lower surface as a basis for curing) is trimmed by two cup wheel 331 polishers. At this time, it is preferable that the particle size of the second cup wheel is thinner. The shape of the concrete molding by the polishing process sequentially made by the two cup wheels is shown in FIG. 4C.

If the upper surface at the time of curing is to be used as the upper surface of the boundary stone after carburizing, it is not necessary to add the process by the upper and lower converter 32 and the lower surface carburizing machine 33. These processes are inserts that can be inserted if needed for dimensioning or surface refinement.

When the top and bottom trimming is completed, the height dimension of the boundary stone is completed, and the remaining thing is to match the width and length dimension of the boundary stone. This is done by cutting the boundary stone. The lower surface of the concrete molding after the process by the carburetor 33 is transferred to the terminal cutter 34 by the conveying belt and the conveying vehicle (21). In the conveying process, the direction change conveying belt and the conveying vehicle 22 are added, which may be added as necessary to change the direction of the line when the length of the process where the process is long is insufficient. . In the embodiment of the present invention, a turn table roller conveyor is used. In the above process, it is preferable to install a shock absorber to absorb the shock generated during rotation.

After the change of direction is made material alignment is made by the air cylinder (23). As the end cutter, a cutter generally used in the stone processing industry may be used, and a cutter used in the art may be used when grinding natural stone. An example of such a cutter is described in Korean Utility Model Registration No. 231371. Six terminal cutting edges 341 are provided in the terminal cutter 34 so as to be parallel to the advancing direction of the concrete molding in two rows. In the embodiment of the present invention, the cutting edges of the first row are 28 inches long and 36 inches of the second row. The number and dimensions of the cutting edges 341 may vary depending on the dimensions of the boundary stone. After the material alignment, the concrete molding introduced into the terminal cutter 34 is separated into seven longitudinal materials by two cutting blades 341 in two rows. This state is shown in FIG. 4D. Five concrete moldings 43 are used to make boundary stones. The remaining material 43 'is left on both sides, so that the material remains on both sides, firstly, the width dimension of the concrete boundary stone is correct, and second, the surface of the boundary stone exposed when the boundary stone is installed is cut or polished. This is to allow the surface pattern to be expressed. If the surface does not need to express the surface pattern or the material can be more precisely aligned, it is not necessary to cut so that the remaining material 43 'on both sides occurs.

Subsequently, chamfering of one side of the upper surface is performed. In this embodiment, five 4-inch cup wheels 351 installed in the chamfering machine 35 chamfer the upper one side of the concrete molding 43. This result is shown in FIG. 4E. Chamfering is a process to prevent the edges of one surface protruding when the boundary stone is installed.

The concrete molding 44 of FIG. 4e is transferred to the transversal cutter 36 by means of a transfer belt and a carriage 21. The cross cutter 36 has three cross cutting edges 361 having a 36 inch dimension and the spacing of the cutting edges 361 is equal to the length dimension of the boundary stone. Moreover, the air cylinder 23 for aligning a raw material at the time of cross cutting is provided. When the concrete molding 44 is positioned in place by the air cylinder, cutting is performed. After cutting, ten boundary stones 45 are completed as shown in FIG. 4F. The remaining material (45 ') of the front and back is to accurately express the length dimension of the concrete boundary stone and express the surface pattern as in the case of the longitudinal cutting. If the surface does not need to express the surface pattern, or if the material alignment can be more precise, it is not necessary to cut so that the remaining material 45 'in front and back occurs.

The finished concrete boundary stone 45 is discharged by the transport belt and the transport vehicle 21.

In the embodiment of the present invention, the end cutting, the chamfering, and the cross-cutting are performed after the calibration, but the order of the end cutting, the cross cutting, the chamfering and the calibrating is not necessarily the same as the embodiment of the present invention. However, it is preferable to follow the embodiment of the present invention.

As a result, in the embodiment of the present invention, as described above, ten boundary stones can be produced in one mold. In addition, the surface pattern can be expressed by grinding or cutting on all exposed surfaces when installing the boundary stone.

As described above, the large-crete boundary stone manufacturing apparatus of the present invention can produce a large number of boundary stones from one molding frame, which enables more efficient production of concrete boundary stones, and can be manufactured with more accurate dimensions by cutting and polishing. At the same time, surface patterns can be expressed.

The present invention is not limited to the described embodiments, and various modifications and changes can be made to those skilled in the art without departing from the spirit and scope of the present invention. Such modifications or modifications may be made to the present invention. It belongs to the claims of the.
