BACKGROUND OF THE INVENTION
The present invention relates to a method for forming a main artificial grass and a method for winding the main artificial grass .
[0002]
[Prior art]
In general, an artificial lawn ground is constructed by laying an artificial lawn directly on a ground layer such as asphalt or concrete or through a cushion layer, and is used in many indoor and outdoor facilities. Here, the artificial lawn is made by planting synthetic resin pile yarns such as nylon and polypropylene to a set length on a synthetic resin base fabric such as polyester and polypropylene, and forming the grass. Due to equipment limitations, it cannot be manufactured beyond a certain width. Therefore, when forming a vast artificial lawn ground, it is necessary to lay several artificial lawns with a certain width in order in the width direction.
[0003]
At this time, simply laying the artificial lawn on the ground surface will move the artificial lawn when a load is applied, so connect a plurality of long artificial lawns in the width direction to form a main artificial lawn with a large width. The ground surface is covered with this artificial grass. For example, as described in Japanese Utility Model Publication No. SHO 59-31763, a pair of adjacent artificial grasses are connected via hook-and-loop fasteners, or as described in Japanese Utility Model Publication No. 1-44562, a welding film is heated. A pair of adjacent artificial grasses can be connected by welding, or the side edges of a pair of adjacent artificial grasses can be sewn as described in the prior art column of Japanese Utility Model Laid-Open No. 60-96403. I try to connect.
[0004]
On the other hand, in order to use the artificial lawn ground for multiple purposes, it is necessary to remove and lay the artificial lawn according to the purpose. Here, in the main body artificial lawn connected by the fastener, each artificial lawn constituting the main body artificial lawn is wound up and removed, or it is drawn out and laid, which requires a lot of work time. is there. Therefore, a method of winding up and removing the main body artificial lawn as it is without separating the artificial lawn, or drawing it out and laying it is preferable in order to shorten the working time. In this case, since winding and unwinding of the main body artificial lawn must be performed using mechanical force, the pulling force acting on the main body artificial lawn is large based on its weight.
[0005]
For this reason, a pressure air outlet connected to an air source is formed on the ground, and when the main body artificial lawn is wound up, the pressure air is ejected from the outlet toward the back of the main body artificial lawn. It has been proposed to reduce the friction and reduce the pulling force (see, for example, Japanese Patent Publication No. 4-17244 and US Pat. No. 4,399,954).
[0006]
[Problems to be solved by the invention]
However, as described above, the method in which the pressure air is ejected from the ground toward the back of the main artificial grass may not be adopted depending on the ground. For example, when the ground is used as a pool in the summer or as a skating rink in the winter, a pressure air outlet cannot be formed in the ground because of the water drainage.
[0007]
This invention is made | formed in view of such a problem, and provides the formation method of the main body artificial lawn which can reduce friction with a ground irrespective of the kind of ground.
[0008]
Moreover, this invention provides the winding method of the main body artificial lawn which can reduce a friction with a ground and can wind up a main body artificial lawn irrespective of the kind of ground.
[0009]
[Means for Solving the Problems]
The method for forming a main body artificial lawn according to the present invention is such that a synthetic resin pile yarn is planted on a synthetic resin base fabric so as to have a set length to form turf leaves, and a cushion is formed on the back surface of the synthetic resin base fabric. A method of forming a main body artificial lawn by connecting a plurality of long artificial lawns with layers of underpads attached in the width direction, and the side edge of each artificial lawn underpad is fixed. A reinforcing tape is adhered to the back side edge of the synthetic resin base fabric of each artificial turf from which the underpad has been peeled off, and then the synthetic resin of a pair of adjacent artificial turf After the side edge of the base fabric is sewed through a reinforcing tape, an air passage and a number of jets that open to the back surface of the air passage are connected to the rear side edge of the underpad. Underpad formed Adhesive, and an air pipe is disposed on the feeding side edge or at least one side edge of the artificial lawn, and the pressure air supplied to the air pipe is reduced by communicating the air pipe with the air passage. It is characterized by being ejected from an ejection port through an air passage.
[0010]
In addition, the method for winding the main artificial grass of the present invention includes connecting an air source to the air piping of the main artificial grass formed by the method for forming the main artificial grass, and underpressure air from the air source from the air piping. It is ejected from the ejection port through the air passage of the pad, and the main body artificial lawn is wound while reducing friction with the ground.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a main body artificial lawn 10 formed according to the present invention. The main body artificial lawn 10 has a set width obtained by sequentially sewing and connecting side edges of a plurality of long artificial lawns 1. It is formed. Then, each artificial lawn 1 constituting the main body artificial lawn 10 is planted on a synthetic resin base fabric 11 such as polyester or polypropylene so that a pile yarn made of synthetic resin such as nylon or polypropylene has a set length. The leaf 12 is formed, and an under pad 13 as a cushion layer is thermally fused to the back surface of the synthetic resin base fabric 11.
[0012]
In order to connect the artificial lawn 1 and form the main body artificial lawn 10, first, the side edge of the under pad 13 of each artificial lawn 1 is peeled over a certain width (see FIG. 2), and then the underglow is removed. An adhesive is applied to the back side edge of the synthetic resin base fabric 11 of each artificial lawn 1 from which the pad 13 has been peeled off to adhere the reinforcing tape T (see FIG. 3), and then a pair of adjacent artificial After the side edges of the synthetic resin base fabrics 11 and 11 of the lawns 1 and 1 are sewed through the reinforcing tape T (see FIG. 4), the synthetic resin base fabrics 11 and 11 of the pair of adjacent artificial lawns 1 and 1 are sewn. An adhesive is applied to the back surface of the side edge portion from which the underpad 13 has been peeled to bond the underpad 131 (see FIG. 5).
[0013]
In this way, the reinforcing tape T is bonded to the back side edge of the synthetic resin base fabric 11 of each artificial lawn 1 through the adhesive, and the synthetic resin of the adjacent artificial lawns 1 and 1 through the reinforcing tape T. Since the side edges of the base fabrics 11 and 11 are sewn with the sewing thread S, the reinforcing tape T itself can support the sewing thread S, and the cured adhesive is used for the synthetic resin base fabric 11. The weave structure of the side edge portion can be reinforced, and a large connection strength can be secured. Therefore, even if a load acts on the sewing connection portion of the artificial lawn 1, 1, the load can be reliably supported, and the woven structure of the side edge of the synthetic resin base fabric 11 of the artificial lawn 1 can be reduced. It is possible to reliably prevent the occurrence of a gap in the connecting portion due to disturbance.
[0014]
Here, the adhesive is preferably a flexible adhesive such as a urethane-based adhesive or a rubber-based adhesive in consideration of a sense of incongruity at the time of competition, a bending action at the time of winding the main body artificial lawn 10 or sewing workability. .
[0015]
Incidentally, as shown in FIG. 6, an air pipe 2 is disposed at the feeding-side edge of the main body artificial lawn 10, and this air pipe 2 can be connected to an air source (not shown) via a coupler 21. Is. Then, as shown in detail in FIG. 7, when forming the main body artificial lawn 10, the underside bonded across the back side edge of the synthetic resin base fabric 11, 11 of the pair of adjacent artificial lawns 1, 1. An air passage 131 a having one end communicating with the air pipe 2 is formed in the pad 131 in the longitudinal direction of the pad 131, and the air passage 131 a opens at an interval toward the back surface of the underpad 131. The large number of jet outlets 131b communicated with each other. As a result, when an air source (not shown) is connected to the coupler 21 and driven, the pressure air from the air source is supplied from the air pipe 2 to the air passage 131a and further ejected from the ejection port 131b.
[0016]
Therefore, when winding up the main body artificial lawn 10, as described above, the coupler 21 and the air source are connected to drive the air source, and the compressed air is ejected from the ejection port 131b through the air pipe 2 and the air passage 131a. If the winding device R (see FIG. 6) is driven in a state in which the main body artificial lawn 10 is lifted from the ground, the friction can be reduced. it can. For this reason, the main body artificial lawn 10 can be wound with a small pulling force, can be wound with a small amount of power, and the pulling force acting on the main body artificial lawn 10 can be reduced. In addition, by forming a passage of pressurized air in the main body artificial lawn 10, it can be used regardless of the type of ground.
[0017]
In addition, since the underpad 131 in which the air passage 131a and the spout 131b are formed in advance may be bonded to the back side edge of the synthetic resin base fabrics 11 and 11 of the adjacent pair of artificial lawns 1 and 1, There is an advantage that it is possible to work using one process when connecting a pair of adjacent artificial grasses 1, 1 and that it can be easily constructed.
[0018]
In the above-described embodiment, the underpad 131 in which the air passage 131a and the jet outlet 131b are formed is used. However, as shown in FIG. 8, the small underpad 132 in which the air passage 132a and the jet outlet 132b are formed. The underpad 131 may be bonded to the underpad 131 and the bonded underpads 131 and 132 may be bonded to the back surfaces of the synthetic resin base fabrics 11 and 11.
[0019]
Further, as shown in FIG. 9, a flexible pipe 3 in which an outlet 3 a is formed as an air passage may be disposed on the back surface of the underpad 131 so as to eject pressure air.
[0020]
Furthermore, in the above-described embodiment, the air passage 131a and the flexible pipe 3 are formed in the longitudinal direction of the main body artificial lawn 10; You may make it form in the width direction of the main body artificial lawn 10 by arrange | positioning in one side edge part over a longitudinal direction, and one end being connected to the air piping 2.
