Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial turf laying device used to lay artificial turf on a ground of a stadium, a floor of an event hall or the like as needed.

[0002]

2. Description of the Related Art Artificial grass that substitutes natural lawn is made by planting grass material made of synthetic resin on a mat material.
Traditionally, as seen in some baseball fields,
It was used by sticking and fixing it on the ground such as soil or concrete, but recently, it is being used in various stadiums and event halls such as laying and removing as needed. is there.

When artificial turf is temporarily laid on a ground, floor or the like, conventionally, for example, artificial turf having a width of 3 to 4 m and a required length is preliminarily wound in a roll shape and the work is performed. A method is adopted in which a worker carries the artificial turf to an area where the artificial turf is laid, and unrolls and unrolls the turf to sequentially lay it down.

[0004]

However, in the case of the above-mentioned conventional method, a large number of artificial turf rolls are unwound by man-in-the-sea tactics. The seams must be treated so that there is no danger of players getting caught on their feet,
Therefore, there is a problem that a great amount of labor and time are required even in the laying work in a relatively narrow range. In some cases, the work of unrolling the artificial turf roll is performed by using a tractor or the like, but since the seam processing work is still manual work, there is a limit to the improvement in efficiency.

Therefore, the present invention is intended to provide an artificial grass laying apparatus which enables efficient laying of artificial grass by a small number of people without the need for a seam processing operation.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a long artificial turf whose length and width are increased so as to correspond to the artificial turf laying area. Both ends of the drum are rotatably supported between the left and right pedestals, and the left and right pedestals are fixed on the left and right carriages that can be driven to travel.

[0007]

[Operation] When laying artificial turf, after aligning the drum with one end of the artificial turf laying area, rotate the drum toward the other end of the artificial turf laying area while rotating the drum to the drum. Unwind the artificial grass that has been wrapped around. As a result, the artificial grass is spread over the entire artificial grass installation area when the cart arrives at the other end of the artificial grass installation area.

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1A and 1B and FIG. 2 show an embodiment of the present invention, in which a plurality of urethane rubber tires 2 are used.
A pedestal 5 is erected on each of the left and right carriages 4 that are driven by the traveling drive motor 3 and have a required diameter and width (axis) between the upper surfaces of the left and right pedestals 5. The long drums 6 each having a length (direction length) are rotatably supported by bearings 7, and a large-sized single piece of artificial grass 8 corresponding to the artificial grass installation area is wound around the drums 6. In addition, the internal gear 9 is provided on both end surfaces of the drum 6.
And the pinion gear 10 meshed with the internal gear 9 is attached to the shaft of the rotary drive motor 11 installed on the outer side of the pedestal 5, and the rotary drive motor 1
By rotating the pinion gear 10 with the drive of 1,
The drum 6 is rotated integrally with the internal gear 9 and the drum 6 is rotated.
The artificial turf laying device 1 is configured such that the artificial turf 8 wound around the unwinding reel is unwound and laid. Furthermore, the artificial grass 8 laid
One end of the artificial turf 8 when winding the drum 6 onto the drum 6.
As a mechanism for holding the drum 6, the electric jack 12 installed on the inner side of the drum 6 can be moved in and out from the outer peripheral surface of the drum 6 in the radial direction at required widthwise intervals of the peripheral wall of the drum 6. Clamp claw 1
3 is provided so that the tip end of the winding start of the artificial grass 8 can be clamped by the clamp claw 13.

In the present invention, a single artificial grass 8 is uniformly spread over a predetermined artificial grass laying area on the ground 14. Therefore, for example, the size of the artificial grass 8 is 50 mm wide. ˜70 m and length 90-100 m, the size of the drum 6 is 3 m in diameter and 70 in width.
It is set to m or more.

The artificial turf laying apparatus 1 of the present invention having such a structure is stored in an underground pit device 15 which is prevented from protruding above the ground 14 when not in use. That is, in the stadium, the pit device 15 is provided on the ground 1 at a position where it does not interfere with the competition.
4, pits 16 are dug with a required depth and width, lifters (indicated by a pantograph type lifter are shown in the figure) 17 are installed at both ends of the pits 16 in the width direction, and on each of the lifters 17, The left and right carriages 4 of the artificial grass laying device 1 can be placed and fixed, and the lifter 1
7 is contracted so that the entire artificial grass laying apparatus 1 can be housed in the pit 16, and
A lid plate 20 that can be vertically rotated (opened and closed) around a hinge 19 at one end as a fulcrum by the expansion and contraction operation of the opening and closing cylinder 18 is arranged at the upper end of the lid, and the upper surface of the lid plate 20 when closed is used as a floor. To be allowed to. In the figure, reference numeral 21 is a stopper portion for closing the cover plate 20, reference numeral 22 is placed on the stopper portion 21 when the cover plate 20 is opened, and the gland 14 and the lifter 1 are placed.
7 shows a spacer for closing a gap between the upper end edge of 7 and.

When laying the artificial turf 8 in a predetermined artificial turf laying area on the ground 14, first, the artificial turf laying device stored in the pit device 15 in a state in which the artificial turf 8 is wound around the drum 6. 1 is carried out from the pit device 15 and moved to the end of the laying area. That is, in this case, the cover plate 20 of the pit device 15 is opened upward by the extension operation of the opening / closing cylinder 18, and the entire device 1 is brought to the level of the ground 14 by the extension operation of the lifter 17, as shown in FIG. After being pushed up, the traveling drive motors 3 of the left and right carriages 4 are driven to drive the carriage 4 so that the drum 6 is aligned with one end point of the artificial grass installation area.

Thereafter, the left and right traveling drive motors 3 are synchronously driven to drive the carriage 4 toward the other end of the artificial grass installation area, and at the same time, the left and right rotation drive motors 1 are driven.
1 is synchronously driven to rotate the drum 6 in a required direction. At this time, by controlling the traveling speed of the carriage 4 to match the rotation speed of the drum 6, the artificial turf 8 is unwound from the drum 6 as the carriage 4 travels, and is laid sequentially. This allows
When the cart 4 travels linearly and reaches the other end of the artificial grass installation area, the artificial grass 8 is spread over the entire area of the artificial grass installation area. After the laying work is completed, the carriage 4 is run to the position of the pit device 15 so that the entire device 1 is stored in the pit 16.

In the above description, since the drum 6 is wound around the artificial grass 8 having a size corresponding to the area where the artificial grass is laid, the drum 6 is rewound and rotated as the carriage 4 travels. The artificial turf 8 can be laid all over the entire artificial turf installation area. Therefore, unlike the conventional method, the work of treating the seam is not necessary and the workers involved are also unnecessary, so that the artificial grass 8 can be laid in a short time by a small number of people. In addition, the device 1 after laying the artificial grass 8 is an underground pit device 15
It is possible to use it as a floor on the cover plate 20 of the pit device 15 during storage without causing any hindrance.

On the other hand, when removing the artificial grass 8,
As in the case of laying, the entire apparatus 1 is taken out of the pit device 15 and moved by the carriage 4 to the unwinding and final point which is the other end point of the artificial grass laying area. Next, after the end of the artificial turf 8 is clamped by the clamp claws 13 on the outer peripheral surface of the drum 6, the drum 4 is wound and rotated, and the carriage 4 is rotated.
To run backwards. As a result, the artificial grass 8 can be wound around the drum 6 while being removed. After the winding is completed, it is stored in the pit device 15.

The present invention is not limited to the above-described embodiment, and the rotation driving method of the drum 6 and the traveling driving method of the carriage 4 may be other than those shown and described, and other books. Needless to say, various changes can be made without departing from the scope of the invention.

[0017]

As described above, according to the artificial turf laying apparatus of the present invention, a long drum capable of winding a large size artificial turf corresponding to the artificial turf laying area is driven to run. Since it is configured to be supported by a trolley that enables it, after aligning the drum at one end of the artificial grass laying area, rotate the drum while running the dolly toward the other end of the artificial turf laying area. By unwinding the artificial grass that has been wrapped around the drum, the artificial grass can be spread over the artificial grass laying area without performing seam treatment, and conversely, the artificial grass can be placed around the drum. The artificial turf can be removed by reversing the bogie while it is being wound up. Therefore, a small number of people can lay and remove the artificial turf in a short time without requiring much labor. There is exhibited an excellent effect that.
