Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a new floor paving device, and more specifically, the present invention relates to a new floor paving device, and more specifically, the present invention relates to a new floor paving device, and more specifically, a resin mortar layer formed on a floor surface regardless of the presence or absence of unevenness on the floor surface, the degree of height difference, etc. The present invention relates to a floor paving device that can make the surface (hereinafter referred to as paved surface) a flat surface.

Conventionally, there have been floor paving devices with various configurations, but
In either case, paving materials (concrete, asphalt, etc.) are laid down on the floor at a constant thickness, and if the floor is paved using a floor paving device with this configuration, the paved surface will almost follow the floor surface. It happens. That is, if there is an unevenness on the floor surface, the paved surface will also have unevenness that is almost the same as the unevenness on the floor surface.

Such irregularities on the pavement surface are not much of a problem when workers are walking or manned machines are running and carrying out the work, but when automatic machines such as industrial robots are running and carrying out the work. If you do,
This is extremely disadvantageous, as explained below.

In other words, automatic machines are usually configured to run, stop, perform necessary work, etc. by reading markers etc. drawn on the pavement surface, or they are configured to run, stop, perform necessary work, etc. based on control signals given from the outside. By setting the size of the automatic machine, the stroke of the work part, and the position of the automatic machine and the workpiece in advance,
The structure is such that gripping, lifting, insertion, etc. can be carried out accurately.

Therefore, if the pavement surface is uneven, the relative position between the automatic machine and the workpiece will deviate from the preset optimal relative position due to the influence of the unevenness, making it difficult to grasp, lift, insert, etc. There is a risk that you will not be able to do it accurately.

For example, when a forklift is set to operate automatically, the vertical position of the forklift's lifting claws may deviate from the vertical position of the claw insertion part of the pallet on which the workpiece is placed, and in extreme cases, lifting There is a risk that the claws may hit the object to be worked on, causing problems such as damage to the object.

The above-mentioned drawbacks could be overcome by equipping automatic machines with the function of detecting and correcting relative positional deviations, for example, but this would make automatic machines more complex and expensive, and furthermore, it would be difficult for automatic machines to perform correction operations. This results in new drawbacks such as increased work time.

An object of the present invention is to eliminate the above-mentioned drawbacks by making it possible to reliably form a paved surface into a flat surface, regardless of the presence or absence of unevenness on the floor surface, the degree of height difference, etc.

In order to achieve this object, the floor paving device of the present invention is supported by a rail extending in a substantially horizontal direction, and is connected to a hopper for supplying resin mortar that is movable in parallel to the rail above the floor surface. The upper surface of the resin mortar supplied from the hopper to the floor surface is made into a flat surface parallel to the rail. A second leveling member provided slightly apart from each other and a third leveling member provided further apart in the horizontal direction are provided, and the first leveling member is the uppermost one and the third leveling member is the uppermost leveling member. This is done by setting the vertical position of the leveling member so that it is at the lowest level.

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings showing examples.

FIG. 1 is a side view showing the floor paving device of the present invention;
Figure 2 is a rear view of the same, in which rails 3, 3 are installed between the upper horizontal rods of the front-shaped gate-shaped support frames 2, 2 erected on the floor 1, and the paving device main body 4 can be moved back and forth. It is suspended from rails 3 and 3.

The support frame 2 has conventionally known height adjustment mechanisms 5, 5 at its lower end, and by operating the height adjustment mechanisms 5, 5... of each support frame 2, 2..., the floor surface can be adjusted. The vertical positions of the upper horizontal rods 6, 6, . . . of the support frames 2, 2, .

By installing the rails 3, 3 between predetermined positions on the lower surfaces of the upper transverse rods 6, 6, . . ., the rails 3, 3 can be made into a straight line extending substantially horizontally.

FIG. 3 is a simplified central vertical sectional side view showing the main body 4 of the paving device, in which a frame 7 made of a plurality of rods is connected to height-adjustable suspension members 8, 8... and rails 3, 3. It is suspended below the rails 3, 3 with rollers 9, 9 rolling on the top. and,
A hopper 10 with an open lower part for charging resin mortar is provided near the forward end of the frame 7, and a diaphragm 10 that is vibrated by a vibrator 12 made of a vibration motor or the like is provided near the return end. A third leveling member 11 is provided, and a hopper 1 is further provided.
A first leveling member 13 made of a wooden rod or the like (hereinafter referred to as a shutter) whose vertical position can be adjusted by contacting the outer edge of the reciprocating side of the lower opening edge of 0
In addition, a second leveling member 14 made of a shutter is provided close to the forward end edge of the third leveling member 11.

Resin mortar regulating sleds 15, 15 are provided near the outside of the left and right edges of the lower opening edge of the hopper 10 and hang down to the floor surface so as to be movable up and down, and are constantly supported by springs 16, 16. It is biased downward.

The first leveling member 13, the second leveling member 14
And regarding the horizontal position of the third leveling member 11,
Although it is possible to set the vertical position as appropriate, it is necessary to set the vertical position so that the first leveling member 13 is the highest and the third leveling member 11 is the lowest. By doing so, the upper surface of the resin mortar supplied from the hopper 10 onto the floor surface is roughly finished with the first leveling member 13, then a medium level finish is performed with the second leveling member 14, and the upper surface of the resin mortar supplied onto the floor surface from the hopper 10 is roughly finished. A final finish is performed using the baffle member 11, and the upper surface of the resin mortar layer can be finished flat.

Note that the first leveling member 13 and the second leveling member 14 are not limited to shutters made of wooden rods; for example, they can be made by applying a satin finish or the like to the lower surface of metal rods. It is possible to use a shutter with a rough surface, a roller that rotates at a circumferential speed faster than the running speed of the frame 7, or a fixed tree shear that reciprocates in a direction perpendicular to the running direction of the frame 7. be.

Also, for the third leveling member 11, a heating iron may be used instead of the diaphragm, or a diaphragm and a heating trowel may be used together.

The operation of the floor paving device having the above configuration is as follows.

Support frames 2, 2 are placed at predetermined positions on the floor 1 to be paved.
After erecting......, operate the height adjustment mechanisms 5, 5... to align the vertical positions of the upper horizontal bars 6, 6..., and then adjust the rail 3 installed below the upper horizontal bars 6, 6... ,3
The paving device body 4 is suspended from the rails 3, 3, and preparation for paving operation is completed.

Therefore, it is only necessary to charge the resin mortar 17 into the hopper 10 and move the frame 7 forward, and the floor surface can be paved in the following manner.

That is, the resin mortar 17 that has fallen onto the floor through the lower end opening of the hopper 10 first touches the floor and the first
The first layer thickness is regulated by the gap with the leveling member 13 and is formed to have a relatively large first layer thickness. At this time, the resin mortar, which has a relatively large lump shape, is only regulated at its highest position by the first leveling member 13, and forms quite large recesses 17' at positions where the lump parts touch each other. (See Figure 4).

Next, the resin mortar 1 is leveled by the second leveling member 14 provided at a lower position than the first leveling member 13.
7 is formed to have a second layer thickness that is thinner than the first layer thickness. At this time, the highest position is scraped off by the second leveling member 14 and the scraped resin mortar is filled into the recess, so that the difference in vertical position between the highest position and the recess 17'' is small. Corrected (see Figure 5).

Thereafter, an intermittent pressing force is applied to the resin mortar layer by a diaphragm provided at a lower position than the second leveling member 14, or a continuous heating pressing force is applied to the resin mortar layer by a heating trowel. , it is possible to form a flat surface with an extremely small difference in vertical position between the highest position and the recess (see FIG. 6).

While performing the above paving operation, the first leveling member 13, second leveling member 14, and third leveling member 11 continue to maintain a constant relative position with respect to the rails 3, 3. The upper surface of the resin mortar layer can be made flat without being affected by the presence or absence of unevenness on the floor surface.

If the floor is paved in the manner described above, the paved surface will become a completely flat surface, and when working with automatic machinery, the automatic machine and the work object can be easily controlled by simply controlling the automatic machine's running and stopping position. The relative position with respect to the object can be set to the optimum relative position, and operations such as gripping, lifting, and insertion can be performed reliably without fear of damaging the object.

Furthermore, since the paved surface made of resin mortar has a non-slip property, the running and stopping positions of automatic machines can be controlled more accurately.

The present invention is not limited to the above-described embodiments. For example, the rails 3, 3 are provided on the floor via a height adjustment mechanism, and the paving device main body 4 is mounted and supported on the rails 3, 3. It is also possible to configure it to do so.

It goes without saying that various other design changes may be made without departing from the gist of the present invention.

As described above, the present invention supplies resin mortar to the floor surface and smoothes the upper surface of the resin mortar layer. This has the unique effect of ensuring that the paved surface is a flat surface parallel to the rails without being affected by the presence or absence of unevenness on the floor surface.
