BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial grass laying device laid on a large-area floor.

[0002]

2. Description of the Related Art Laying artificial turf on large-scale floors of sports facilities has become popular. Since these facilities are used for multiple purposes, it is necessary to lay or remove artificial turf according to the purpose, and therefore artificial turf is often wound or laid. Conventionally, this artificial grass has been wrapped around (1) as much as possible at once by blowing air from the air outlet provided on the floor to reduce the frictional resistance between the floor surface and the artificial grass. A method of laying and (2) a method of winding artificial turf divided into a width of 4 m and a length of about 40 m by a self-propelled machine such as a forklift are known.

[0003]

In the above method (1), since a wide artificial grass is laid all together, a small number of people can perform laying work in a short time. The equipment cost becomes high because it is necessary to provide an air outlet. Further, there is a drawback that it is not easy to repair wrinkles and misalignment of the laid artificial grass. In the method (2), the apparatus is small and the cost is low, but since the divided artificial grass is laid, a large amount of work is required and a large number of workers and a long working time are required. Technically, it is not easy to eliminate the displacement of the joint.

[0004]

The present invention follows the method of (1) above and allows a small number of people to carry out laying work in a short time, and
The present invention relates to a laying device for artificial turf that can be laid without generating wrinkles on the artificial turf, and has a large number of roller receiving rollers provided in parallel along the rotation axis direction and placed on the roller receiving rollers. A plurality of sets of rotating rollers, a trolley provided with one artificial turf roll and one wrinkle removing roller placed on the plurality of sets of rotating rollers, and connected to the trolley via an arm, It is a laying device for artificial turf which is composed of another wrinkle-removing roller and one pressing roll that are provided in parallel along the rotation axis direction.

The first gist of the present invention is that a large number of roller receiving rollers and a plurality of sets of rotating rollers are provided from below to rotate a large weight artificial turf roll having a length of several tens of meters without bending. It is the point of supporting and driving the rotating roller to rotate the artificial turf roll by friction.

The second gist of the present invention is to provide two wrinkle removing rollers, and when the artificial turf is laid, the force for spreading the artificial turf laterally by bringing the respective wrinkle removing rollers into contact with the front and back of the artificial turf. This is to prevent the generation of wrinkles by acting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.

FIG. 1 shows an example of the winding device of the present invention.
(A) is a longitudinal sectional view at the time of laying, (b) is a side view at the time of winding, and (c) is a surface view of a wrinkle removing roller.

The artificial turf 1 is wound into a roll on a take-up roller 2A and stored in the form of an artificial turf roll 3. A large number of roller receiving rollers 5 are installed on the carriage 7, and the rotating rollers 4A and 4B are placed at a ratio of one to four to five pairs of the roller receiving rollers 5. The rotating rollers 4A and 4B are about 2 m long and are installed at a ratio of one set every 4 to 5 m along the rotation axis direction. Therefore, it is necessary to install several to more than ten sets of rotating rollers 4A and 4B according to the length of the artificial turf roll 3. Each pair of rotating rollers 4A and 4B is driven by an electric motor 6. In addition to these roller groups, a wrinkle removing roller 8A fixed to the carriage 7 is provided, and another wrinkle removing roller 8B and a pressing roll 9 are connected to the carriage 7 via an arm 10. The dolly 7 may be self-propelled with an engine or electric motor mounted, or may be pulled by a winch via a wire to be moved. On the other hand, artificial grass 1
Is wound around the winding roller 2A and stored in the form of an artificial turf roll 3. This artificial turf roll 3 is placed on a plurality of sets of rotating rollers 4A, 4B. Move the cart 7 in the laying direction of the artificial turf 1 to rotate the rollers 4A, 4B.
To rotate the artificial turf 1. Artificial turf roll 3
Is rotated by friction with the rotating rollers 4A and 4B, and the artificial grass 1 is sent out. The artificial turf 1 is fed out with an appropriate degree of slack by adjusting the moving speed of the carriage 7 and the rotating speeds of the rotating rollers 4A and 4B, and the artificial turf 1 is tense due to the weight of the wrinkle removing roller 8B and the pressing roll 9. While contacting the front wrinkle removing roller 8B and the back wrinkle removing roller 8A, they reach the floor surface and are pressed against the floor surface by the pressing roll 9 to proceed with the laying. As shown in (c), spiral wrinkles 11 are provided on the surfaces of the wrinkle removing rollers 8A and 8B, and the wrinkle removing rollers 8A and 8B serve to laterally spread the contacting artificial turf 1. The winding roller 2A gradually approaches the position of the winding roller 2B as the laying progresses, and stops at the position of the winding roller 2B when the laying is completed.

At the time of winding, as shown in FIG. 1B, the wrinkle removing roller 8B attached to the arm 10 is rotated so as not to come into contact with the artificial turf 1. The carriage 7 is moved in the winding direction of the artificial turf 1, and the rotating roller 4
Rotate A and 4B in the direction in which the artificial grass 1 is wound up. The take-up roller 2B is rotated by friction with the rotating rollers 4A and 4B to start winding the artificial grass 1, and then the artificial grass roll 3 around which the artificial grass 1 is wound is rotated by the rotating rollers 4A and 4B. The turf roll 3 is rolled up with little slack, and the diameter of the artificial turf roll 3 is increased. Since the weight of the wrinkle removing roller 8B attached to the arm 10 is not applied to the artificial turf 1, the artificial turf 1 does not come into contact with the wrinkle removing roller 8A fixed to the carriage 7 and is wound directly on the artificial turf roll 3 from the pressing roller 9. Taken.

[0011] During winding, there may be a case where the artificial grass 1 is fed at both sides in the width direction or the speed of winding is inconsistent. To cope with this, the moving speeds on both sides of the carriage 7 may be adjusted to achieve harmony, but as an alternative method, the rotation speeds of several to ten or more pairs of rotary rollers 4A, 4B installed on the carriage 7 may be respectively adjusted. It can be adjusted independently, and artificial turf 1
It is preferable that the feeding or winding speed can be independently adjusted in each of the widthwise sections.

2A and 2B show an example of laying artificial turf by using the winding device of the present invention. FIG. 2A is a plan view and FIG. 2B is an elevation view.

The winding device 12 is connected to a winch 14 via a wire rope 13 and moves in the laying direction. One end of the artificial turf 1 is fixed to a fixed portion 15 in the pit. The artificial turf roll 3 is placed on the wrapping device 12, and the artificial turf 1 is laid on the floor surface 17 as the wrapping device 12 moves.

In the case of winding, the wire rope 13 is once connected to the winch 14 via a pulley (not shown) attached to the hook 16 so that the winding device 12 moves in the winding direction with the moving direction reversed. To do.
