Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a structure for laying artificial grass.
[0002]
[Prior art]
The conventional artificial turf laying structure employs a configuration as shown in FIG.
That is, a structure is adopted in which an air supply hole b is provided in the floor surface a where the artificial turf d is to be laid, and a blower c is installed inside the air supply hole b.
Or as shown in FIG. 9, the structure which opens the compressed air manufactured with the large sized fan c through several pipes e under the floor is employ | adopted.
When the artificial turf d is unfolded and stored, the air generated by the blower c is blown to the back of the artificial turf d to be lifted from the floor a by a certain distance, and the artificial turf d is pulled by a winch or the like.
In addition, the artificial turf is wound up by directly winding it around the winding drum f as shown in the figure.
[0003]
[Problems to be solved by the present invention]
The above-described conventional artificial grass laying structure has the following problems.
<I> It is difficult for compressed air to be supplied in a well-balanced manner to the entire back surface of the artificial turf. For this reason, the entire surface could not be lifted smoothly, and a large traction force was required for the development of the artificial turf.
<B> After supplying compressed air, the air on the back side of the artificial turf could not be completely removed, and some air pockets were generated, resulting in irregularities on the surface of the turf.
<C> Since the air blower is installed for each air supply hole, the air blower and the artificial turf are close to each other. If the air blower is heated for some reason, the artificial turf may be damaged. .
<D> Since the artificial turf is directly wound around the drum, compression deformation is likely to occur due to the concentrated load generated on the bearing as the winding thickness increases.
As a result, winding slack may occur and smooth winding may be difficult.
<E> In the process of winding up artificial turf with a width of several tens of meters, a difference in the amount of winding may occur depending on the position. Then, it was impossible to form an orderly winding cylinder, and the position shifted to the shape of a bamboo shoot for each turn, which required a great deal of labor for correction.
[0004]
The present invention has been made to solve the above-described conventional problems, and can smoothly float the entire surface of the artificial turf, enabling smooth and accurate deployment and take-up and storage without requiring a large traction force. An object is to provide a structure for laying artificial turf that is possible.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, the artificial grass laying structure of the present invention is configured by opening air supply holes on the floor surface and laying artificial grass on the floor surface. An artificial turf winding drum is provided on a part of the floor surface, and a winding receiving belt is disposed below the winding drum. The winding receiving belt includes a plurality of rollers arranged in parallel with the winding drum. One of the rollers that are wound around the belt and configured at a predetermined interval and wound around the take-up receiving belt is characterized by an artificial grass laying structure that is connected to a rotational drive source.
[0006]
[Embodiments of the present invention]
Embodiments of an artificial grass laying structure according to the present invention will be described below with reference to the drawings.
[0007]
<I> Levitation device.
A large number of air supply holes 3 are opened on the floor surface 2 on which the artificial turf 1 is to be laid in an average dispersed state. Instead of installing a blower directly in the air supply hole 3 as in the prior art, the exhaust pipe of the air supply pipe 4 is opened. Each exhaust pipe is connected to, for example, an air supply pipe 4 piped below the floor surface 2, and the other end of the air supply pipe 4 is connected to the compressor C. (Figure 1)
[0008]
Alternatively, without using the air supply pipe 4, the air supply holes 3 can be opened by using a part of the floor as a double floor and using the space between them as an air passage. (Figure 2)
If the artificial turf 1 is laid on the floor 2 in this state, compressed air can be ejected from the numerous air supply holes 3 dispersed on the average toward the back of the artificial turf 1.
Alternatively, if the compressor C is set to a negative pressure, the laying state in which the air remaining on the floor 2 and the back of the artificial turf 1 is sucked using a large number of air distribution holes 3 dispersed on average so that no air pool remains. It can also be formed.
[0009]
<B> Winding device. (Figure 3)
A lawn storage chamber 5 is provided at the end of the floor 2 on which the artificial turf 1 is laid.
A winding drum 6 of the artificial turf 1 is installed inside the storage chamber 5. The winding drum 6 is supported by the lifting unit so that the position of the winding drum 6 increases as the diameter of the wound artificial turf 1 increases. The elevating unit can employ a configuration in which an increase in the weight of the take-up drum 6 is detected and the drum 6 is raised and lowered by expansion and contraction of a jack.
A take-up receiving belt 7 is disposed below the take-up drum 6. The take-up receiving belt 7 is wound around a plurality of rollers 8 arranged in parallel with the take-up drum 6 and configured at a predetermined interval.
[0010]
The winding roller 8 is arranged in parallel on both sides of the winding drum 6 in a plane. Further, a tension roller 9 is disposed inside the winding receiving belt 7 in order to give a certain tension to the winding receiving belt 7.
One of the rollers around which the take-up receiving belt 7 is wound is connected to a rotational drive source via a chain or a gear.
The rotation of the take-up drum 6 and the amount of movement of the take-up receiving belt 7 are synchronized via a gear or the like. As the take-up diameter increases, the amount of movement of the take-up receiving belt 7 increases, It is set so that the amount of movement of the take-up receiving belt 7 decreases with the decrease.
[0011]
<C> Adjustment mechanism for the amount of winding.
A guide roller 10 is provided between the laying portion of the artificial turf 1 and the winding drum 6 of the artificial turf 1. The guide roller 10 is a roller having a horizontal rotation axis.
The guide roller 10 can be configured by giving a function of adjusting the amount of movement of the artificial turf 1.
In that case, for example, as shown in FIG. 4, the guide roller 10 is formed by projecting a spiral strip 12 wound in the opposite direction with the center as a boundary. Then, when the artificial turf 1 is wound, a tensile force is applied to both sides of the artificial turf 1 by the spiral strip of the guide roller 10, and a uniform amount can be wound in a state where the artificial turf 1 is always tightly pinched.
[0012]
Alternatively, as shown in FIG. 5, an adjustment roller having a function of adjusting the amount of movement of the artificial turf 1 can be arranged close to the guide roller 10.
This adjusting roller is constituted by a divided roller 11 obtained by dividing one roller into a plurality of rollers. A direction control device such as a jack is attached to the vertical shaft that supports the horizontal rotation shaft of each divided roller 11.
Usually, the division roller 11 is set with its rotation axis directed in a direction orthogonal to the moving direction of the artificial turf 1. If eccentricity of the entire turf occurs during winding of the artificial turf 1, a part of the divided rollers 11 is rotated at an angle that is not perpendicular to the moving direction of the artificial turf by the direction control device. Then, the amount of movement in the direction orthogonal to the winding direction of the artificial turf 1 changes when the divided roller 11 hits.
By adjusting the angle of the dividing roller 11, the amount of change in movement can be adjusted, and the overall eccentricity of the artificial turf 1 can be corrected.
[0013]
Or the some division | segmentation roller 11 is set toward the direction which cross | intersects the moving direction of the artificial grass 1 from the beginning. And this division | segmentation roller 11 is set so that raising / lowering is possible. Usually, the dividing rollers 11 are lowered, and when some eccentricity occurs when the artificial turf 1 is wound, some of the dividing rollers 11 are raised.
Then, the moving amount of the artificial turf 1 is changed by hitting the raised divided roller 11, and the entire eccentricity of the artificial turf 1 can be corrected.
[0014]
Or as shown in FIG. 6, as a roller for adjusting the amount of eccentricity of the artificial turf 1, sandwiching rollers 13 are installed at positions on both sides of the artificial turf 1 with the artificial turf 1 sandwiched from above and below. Since the sandwiching roller 13 is arranged so as to hold the artificial turf 1 from both the upper and lower sides, the artificial turf 1 can freely move in the moving direction, but the movement in the direction orthogonal to the moving direction is restricted. To do.
Therefore, when the winding state of the artificial turf 1 becomes uneven, the artificial turf 1 can be forcibly pushed out or pulled in a direction perpendicular to the moving direction by expansion / contraction of the jack, so that the normal winding state is obtained. It can be corrected.
[0015]
Alternatively, as shown in FIG. 7, a plurality of winches 15 are arranged on the artificial turf 1 from the side opposite to the installation position of the winding drum 6 of the artificial turf 1. The winch 15 gives the artificial turf 1 a tensile force smaller than the winding force of the winding drum 6. If the winding state of the artificial turf 1 becomes non-uniform, it can be corrected to a normal winding state by adjusting the tensile force for each winch 15 according to the state. Alternatively, if the plurality of winch 15 groups are divided into two groups on the left and right, and a tensile force is applied to the artificial turf 1 by the winch 15 group of any group during winding, the winding state of the turf 1 can be corrected. it can.
[0016]
<D> How to raise the turf.
When the artificial turf 1 is pulled out and laid, or when the laid artificial turf 1 is stored, compressed air is supplied from the compressor. Then, the compressed air can be supplied from the air supply hole 3 to the back surface of the artificial turf 1 through the air supply pipe 4.
By appropriately adjusting the distribution of positions where the air supply holes 3 group are installed and the supply pressure of the compressed air, the entire surface of the artificial turf 1 can be floated in an appropriate state.
As a result, the artificial turf 1 can be laid and stored with a slight traction force. If the air remains between the floor surface 2 and the back surface of the artificial turf 1 after the artificial turf 1 is laid, irregularities are generated. In such a case, negative pressure is supplied from the compressor C. That is, by sucking and exhausting, the residual air is sucked smoothly, and the artificial turf 1 can be brought into close contact with the floor surface 2 to form a laying state in which no air pool remains.
[0017]
<E> Winding and unwinding artificial turf 1
When the artificial turf 1 is wound up, the artificial turf 1 is lifted and the winding drum 6 in the storage chamber 5 provided at the end of the floor surface 2 is rotated.
A take-up receiving belt 7 is disposed below the take-up drum 6, and the take-up receiving belt 7 is wound around a plurality of rollers 8 arranged in parallel with the take-up drum 6 and configured at a predetermined interval. It is. Further, the rotation of the winding drum 6 and the movement of the winding receiving belt 7 are synchronized.
Therefore, the cylindrical body of the artificial turf 1 wound around the winding drum 6 increases in diameter in a state where the lower surface is supported by the belt 7, and the belt 7 moves at high speed as the diameter increases, and the winding is performed. The position of the take-up drum 6 gradually rises.
As a result, the wound artificial turf 1 continues to rotate in a state where the lower surface in the cylindrical state is always supported by the belt 7, and there is no occurrence of partial loosening.
When unwinding the artificial turf 1, the artificial turf 1 is lifted and one end of the artificial turf 1 is pulled out with a winch or the like.
[0018]
[Effect of the present invention]
Since the construction of the artificial turf 1 according to the present invention is as described above, the following effects can be obtained.
<I> Supply of compressed air is different from the conventional configuration in which a blower is provided in each air supply hole 3 and is a structure in which the air is blown from the air supply holes 3 by a small number of compressors. Can be distributed.
Therefore, the compressed air can be supplied to the entire back surface of the artificial turf 1 in a well-balanced manner, and the whole can be floated smoothly. Therefore, when the artificial turf 1 is deployed and stored, it can be smoothly performed with a small traction force and driving force.
<B> After the artificial turf 1 is laid, the air on the back surface cannot be completely removed, and an air pocket may be generated in part. At that time, by supplying negative pressure from the air supply hole 3 to the back surface of the artificial turf 1, the residual air is sucked smoothly, and the artificial turf 1 is brought into close contact with the floor 2 to form a laying state in which no air pool remains. be able to.
<C> Each air supply hole 3 is simply opened by an exhaust port. Thus, since the supply source of pressurized air and the artificial turf 1 are not close to each other, the artificial turf 1 is not affected even if a part of the apparatus or device is heated for some reason.
<D> When the artificial turf 1 is wound around the drum 6, the artificial turf 1 whose diameter increases from the lower surface thereof is supported by the belt 7. Therefore, even if the winding thickness is increased, no concentrated load is applied to the cylindrical body of the artificial turf 1, and it is possible to perform smooth winding without causing compression deformation.
<E> Since the artificial turf 1 moves in a well-floating state, the frictional resistance can be remarkably reduced, and the durable life of the artificial turf 1 itself can be improved.
<F> Since the amount of winding of the artificial turf can be adjusted, the winding position can always be kept constant. Therefore, it is possible to prevent the occurrence of bamboo shoot-like random winding and to wind up into an orderly and accurate cylinder.
