Abstract

PURPOSE:To obtain artificial lawn having improved drainage, fixing properties, and cushioning properties, by sticking a backing material on a belt-like mat having lawn pile, forming a great number of protrusions in one piece on the surface, and boring a great number of drainage holes passing through the mat. CONSTITUTION:The backing material 6 is stuck on the belt-like mat 5 having the lawn pile 51 by a backing mechanism, and a pasty resin solution having the same material as that of the backing material 6 (e.g., PVC) is dropped on the surface of the mat, so a great number of the protrusions 61 are formed in one piece at equal longitudinal and lateral intervals. Then, a large number of the drainage holes 7 passing through the mat are formed on the belt-like mat 5 by a boring mechanism, to give artificial lawn having improved drainage and fixing properties which have never existed hitherto.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a method and apparatus for producing artificial turf.

<Summary of the Invention> This invention applies a backing material to a belt-shaped mat having grass piles, drips a resin liquid onto the surface of the backing material to form a large number of protrusions in one, and The drainage performance of the artificial turf is improved by providing a large number of drainage holes that penetrate the front and back sides of the strip-shaped mat containing the artificial turf.

<Background of the Invention> Conventional artificial turf is usually constructed by pasting a strip-shaped backing material of the same width to a strip-shaped base material on which piles forming a grass surface are planted. When such artificial turf is installed outdoors, drainage is always a problem. It is also possible to install a perforation mechanism downstream of the artificial turf production equipment and sequentially drill drainage holes in the artificial turf that is being fed out, but in this case, there may be problems with drainage holes and the piles located around the holes. arise. Furthermore, since the lower opening of the drain hole is blocked by the floor or ground, drainage problems still remain in the case of concrete floors.

<Object of the Invention> In view of the above-mentioned problems, an object of the present invention is to provide a novel method and apparatus for producing artificial turf that has good drainage, improved adhesion to the floor surface, and improved cushioning properties.

<Structure and Effects of the Invention> In order to achieve the above object, the present invention attaches a backing material to a belt-shaped mat having a lawn vile, and drips a resin liquid onto the surface of the backing material to integrate a large number of protrusions. A large number of drain holes are formed and penetrate through the belt-shaped mat including the backing material from the front and back sides.

According to the above configuration, in this invention, a floating gap suitable for drainage is formed between the numerous protrusions of the backing material and the floor surface on which it is laid, and the water on the mat flows into the gap through the drainage holes, and immediately The invention has the effect of achieving the purpose of the invention, such as being able to eliminate the drainage problem of artificial turf all at once.

<Description of Examples> FIG. 1 shows an overall schematic diagram of an artificial turf manufacturing apparatus, showing a backing mechanism 1 for attaching a backing material 6 to a belt-shaped mat 5 having a grass pile 51, and a A plating mechanism 2 disposed on the feeding side and integrally forming a large number of protrusions 61 at appropriate intervals by dropping a paste resin liquid of the same material or the same type onto the surface of the backing material 6, and the plating mechanism 2 A perforation mechanism 4 is provided on the downstream side of the mat via a hot air processing unit 3, and forms a large number of drain holes 7 that are equally spaced and penetrate from the front and back sides of the belt-shaped mat 5 including the backing material 6. Equipped with

The lining mechanism 1 has a lining material 6 wound into a roll on the carry-in side, and a belt-shaped mat 5 folded in series downstream of the lining material 6, set in a pile-down state, and the lining material 6 and the belt-shaped mat 5 are The material is transported to a defined transport path by a transport means 11 such as a roller, a net conveyor, or a belt conveyor. Each conveyance path is equipped with a heating device 12 such as a plate heater to heat each to a predetermined temperature. The application roller 13 is provided to apply p, v,
A resin liquid such as c is applied and continuously adhered to the pile-down belt-shaped mat 5 at the confluence part.

The resin liquid plating mechanism has a plurality of pouring nozzles 22 attached to an arch-shaped support frame 21 arranged on the feeding side of the lining mechanism 1, and each nozzle 22 adjusts the amount of liquid supplied and the amount of air supplied. It is connected to a liquid supply pipe 24 via a dosing valve 23. The liquid supply pipe 24 is connected to a liquid tank (not shown) via a pressure feeding means such as a pump or a piston cylinder, and each valve is operated intermittently in conjunction with the feeding operation of the strip mat 5. , thermosetting resin liquids such as P, V, and C contained in the liquid tank are dripped onto the surface of the lining material 6 from the spout of each nozzle 23.

The hot air processing unit 3 applies hot air at a predetermined temperature to the belt-shaped mat 5 to form an integral bond between the mat 5 and the backing material 6 and to form an integrally bonded protrusion 61 on the surface of the backing material 6 in which the resin liquid is solidified. The protrusion 61 has a foam structure depending on the gas-liquid ratio determined by the dosing valve 23.

As shown in FIG. 4, the perforation mechanism 4 includes a perforation roller 41 having a large number of perforation pins 42 implanted on its outer circumferential surface and a support roller 43 movable up and down, which are arranged opposite to each other at the upper and lower parts of the mat conveyance path.

The perforation roller 41 is provided with a heat generating heater (not shown) therein to heat the perforation pin 42 (approximately 200° C. to 300° C.), and perforates the drain holes 7 in the mat 5 during transfer. At the same time as this drilling, the circumferential surface of the hole is immediately solidified by the thermosetting backing material 6, thereby preventing the pile 51 located in the hole from coming off.

As described above, the present invention attaches the backing material 6 to the belt-shaped mat 5 having the lawn vile 51, drips a resin liquid onto the surface of the backing material 6 to integrally form a large number of protrusions 61, and then Since a large number of drainage holes 7 penetrating the front and back surfaces of the mat 5 including the mat 6 are formed, the artificial turf of the present invention has floating gaps formed between the mat 5 and the floor surface 8 by the respective protrusions 61, and the drainage holes 7 Since the lower opening communicates with the gap, the conventional drainage problem can be completely solved. Moreover, the present invention has the advantages of
The desired artificial turf can be obtained by simply adding the plating structure 2 for dripping the resin liquid and the perforating mechanism 4, thus realizing mass production without the need for special equipment. Further, since the water drain hole 7 is formed using a heated drilling pin 42 so that the circumferential surface of the hole is immediately solidified during drilling, there is no problem in draining the bail 51, which has the effect of achieving the purpose of the invention.
