DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete material leveling device for filling a mold with concrete material and leveling the top surface of the filled concrete material.

[0002]

2. Description of the Related Art A concrete flat plate, for example, a concrete molded product whose filling side of a molding die is a flat surface, has been manufactured by pouring concrete material into a molding die, pressing the upper surface of the poured concrete material, and then curing it. It is made by removing it. When the molded product is a flat plate, the pressing process has a very important meaning. That is, the density of the concrete material in the molding die is extremely uneven just by filling the molding die with the concrete material, and even if it is cured as it is, it is easily broken at the time of die cutting and the productivity is remarkably lowered. If pressure is applied with a press before curing, the density of the concrete material in the mold will be uniform, and it will not break even during mold removal, improving both productivity and quality.

[0003]

Although many attempts have been made to mechanize the above-mentioned conventional method for forming concrete molded products such as concrete flat plates, the press process has been an obstacle to automation, and full automation has been realized. Absent.

That is, there are various types of molding dies, and it is very difficult to uniformly apply the mechanical force by the press to the filled fluid-like raw concrete material, and even under the present circumstances, the die cutting caused by the pressing process is caused. About 20% of the time is broken.

The present invention has been made to solve the above-mentioned conventional problems, and its object is to realize the automation of the molding of concrete molded products such as concrete flat plates, and the concrete material having high productivity. To provide a leveling device.

An embodiment of the present invention will be described below with reference to the drawings. 2 is a front view of a concrete leveling apparatus according to an embodiment of the present invention, and FIG. 3 is a right side view of FIG. This concrete material leveling device is a device for automatically molding a concrete molded product in which the filling side of the molding die 1 is a flat surface. In this embodiment, it is an automatic molding device for obtaining a concrete flat plate. It is characterized in that the pressure vessel 2 to which pressure (wind pressure) is applied is provided.

The pressure vessel 2 is provided with an open bottom portion which is substantially aligned with the upper surface of the molding die 1 and a charging port 5 with a lid 4 for charging the kneaded concrete material 3. The lid 4 is hinged on the upper surface of the container body and is opened and closed by a fluid pressure cylinder 6.
The lid 4 is provided with an air supply port 7 that can be connected to a duct via a connection conduit 7A, and an air flow from a blower or a compressor is pressure-fed via the duct. A sealing material 8 as an airtight holding member is provided on the contact surfaces of the lid 4 and the container body.

One end of a movable arm 9 as a sliding means for horizontally reciprocating horizontally in FIG. 2 is fixed to one side of the pressure vessel 2 and is supported by the movable arm 9. Reference numeral 9A is a guide roller for smoothly reciprocating the movable arm 9, and is supported by a support member (not shown). On both sides of the bottom of the pressure vessel 2, leveling rollers 10 are axially supported in a direction orthogonal to the moving direction (the left-right direction in FIG. 2). As shown in FIG. 4, these leveling rollers 10 have the width of the side surface of the pressure vessel 2 and are borne by the bearings 2B of the side plates 2A and covered by the cover 11 attached to the outer wall of the pressure vessel 2. It is being appreciated. One shaft 10A is projected to the outside of the cover 11 and a drive chain wheel 10B is attached. Each leveling roller 10 is rotated in the same direction via a chain 12A by a drive device 12 mounted on one side of the pressure vessel 2. In addition, 1
2B is a tension roller for the chain 12A. At least the rotating surface of each leveling roller 10 is made of an elastic body 13 such as rubber, and the lower ends of these rotating surfaces are located substantially on the same surface as the lower end of the pressure vessel 2.

The molding die 1 is installed at a position where its upper surface is substantially aligned with the bottom of the pressure vessel 2, and a flat plate-shaped slit plate 14 is provided on the outer side corresponding to the moving direction of the movable arm 9 so as to be flush with the upper surface. It is set up. The spill board 14 prevents the concrete material 3 from spilling. A seal plate 15 made of urethane is provided on the outside of the cover 11 to prevent concrete from leaking between the pick-up plate 14 and the lower end of the cover 11.

In the leveling device having the above-mentioned structure, the concrete material 3 is put into the molding die 1, and the concrete material 3 is put into the molding die 1.
It is possible to automatically carry out the pressure filling and the flat finishing by leveling the upper surface of the filled concrete material 3. That is,
As shown in FIG. 1, when the kneaded concrete material 3 is put into a pressure vessel 2 whose bottom portion is substantially aligned with the upper surface of the mold 1, and the air flow is sent from the air supply port 7, the pressure vessel 2
The internal pressure of the inside rises, a substantially uniform pressure is applied to the entire concrete material 3 in the pressure vessel 2, and the concrete material 3 flows downward and can enter the molding die 1 in a pressurized state.

Subsequently, the horizontal movement of the movable arm 9 causes the pressure vessel 2 to horizontally reciprocate on the upper surface of the molding die 1 and on the pick-up plate 14, so that the concrete material 3 is filled in the molding die 1 at a substantially uniform density. Go. At this time, the leveling roller 10 rotates the upper surface of the pressure vessel 2 along the moving direction thereof, and the concrete material 3 in the pressure vessel 2 and the concrete material 3 in the molding die 1 are caused by the horizontal reciprocating movement of the pressure vessel 2. The unevenness of the concrete material 3 caused by the friction is avoided, and the concrete material 3 on the upper surface of the molding die 1 is flattened. After that, the concrete material 3 is cured together with the molding die 1, and the concrete flat plate S shown in FIG. Since the concrete material 3 filled in the molding die 1 is pressed by air pressure, rocked by the reciprocating movement of the movable arm 9, and leveled by the leveling roller 10, there is no variation in the density throughout, so it breaks at the time of die cutting. It rarely happens. Further, even if the depth or size of the molding die 1 changes, it can be dealt with only by changing the installation of the picking plate 14. The upper surface S1 of the obtained concrete flat plate S was a good flat surface.

The leveling roller 10 can be set only on one side by setting the moving range of the movable arm 9 to a large range, but it is effective to prevent unevenness of the concrete 3 due to friction when it is provided on both left and right sides. And the filling time can be shortened. Further, the movable arm 9 may be configured as a swing arm that reciprocates in a circular arc on a plane.
