【発明の詳細な説明】 （産業上の利用分野） 本発明は、支持床部から人工芝を除去する方法に関する
ものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method for removing artificial turf from a supporting floor.

（従来の技術およびその問題点） 競技場を覆うのに人工芝を用いることが知られている。(Conventional technology and its problems) It is known to use artificial turf to cover stadiums.

一般に、人工芝は、適当な基礎の上に取付けられ、取り

人工芝を除去していた。Recently, it has become desirable to use artificial turf as a surface on which one or more types of sports are played. For example, it may be desirable to quickly change the surface from a field suitable for football to a field suitable for basketball. In this case, to play football, artificial turf was spread over a wooden basketball floor, while to play basketball, the artificial turf was removed to expose the wooden floor. In other cases, it is desirable to quickly convert a field suitable for football into one suitable for rodeo competitions. In this case, artificial turf was spread over a mud foundation for football, and the artificial turf was removed for rodeo competitions.

動させることが困難であると言う問題である。Several difficulties arise when converting a field from one sport to another by expanding or removing artificial turf. One of the main problems is that artificial turf is very heavy, large, and bulky, making it difficult to place or move around the playing field.

のであった。US Pat. No. 4,399,954 discloses a method for removing or installing artificial turf from a playing field. This method was accomplished by supporting the artificial turf on an air cushion, which substantially reduces the force required to pull or pull the artificial turf onto the playing field.

An air cushion with an operating pressure corresponding to the water head of the table is generally sufficient to support an expanded artificial turf with a standard weight of 2.4 to 12.2 kg/mm2 (0.5 to 2.5 ρb/ft2). . One drawback of the system shown in this US patent is that it must be used in a closed stadium. This means that over a period of time, dirt and dust in the air will accumulate in and on the artificial turf in areas where it cannot be moved.
It could not be used, especially in the western United States. For example, density 1200kg/m3 (76I!, h/ft3
) corresponding to dust having a specific gravity of at least 1.2, for example consisting of dry and friable soil. It is assumed that part of the artificial turf that has spread as a result of the dust storm is 4.8
Assuming that it is covered with dust to a depth of mm (3/16″),
The standard weight of artificial turf supported by air cushions is approximately 5.8 kg/c! (1,2421) / f
t2). For this reason, it is difficult to use a pneumatic cushion to cover a part of the artificial turf that is deeply covered with dust, and an excessive tensile force is applied to the artificial turf. This excessive pulling force may tear the artificial turf or produce adverse results.

In one part of the path, the artificial turf is pulled from the playing field to the take-up roll along the path where the artificial turf turns over.This method allows the mud, etc. contained in the artificial turf to be removed from the artificial turf into the collection area. Preferably, a force is applied to the artificial turf at a portion thereof to remove mud etc. from the artificial turf.This force is applied by means of an air jet, a swatting stick, or a carpet cleaner. It can be given by the Haku equipment.

〈実施例） 以下図面を参照して本発明について詳述する。<Example) The present invention will be described in detail below with reference to the drawings.

Artificial turf is often bonded to a shock absorbing pad (not shown) attached to the bottom. The artificial turf is attached to the floor 12,
or removed, it is preferable to support the floor portion 12-H via an air cushion, as disclosed in U.S. Pat. No. 4,399,954.

The artificial grass 11 passes through an idle roller 21 attached to the opposite side of the wall of the bit, and then passes through a second idle roller 22 supported by an idle roller 23. The artificial grass then passes over the second roller 22, ie between rollers 22 and 23. The path of the artificial grass 11 from the rollers 22 passes under a take-up roll supported by rollers 27.

From the figure, this part regarding the path of the artificial grass is the roller 22
from approximately the 8 o'clock position to approximately the 4 o'clock position of the take-up roll 26. By arranging the artificial turf 11 in this manner, mud and dust accumulated thereon can be removed. If necessary, a chute 33 and a belt conveyor 34 (as well as a vacuum dust collector) can be used to remove the dirt that has fallen from the artificial turf 11. Further, a nozzle 37 may be provided which faces the artificial turf 11 at a distance and injects air directly onto the turf material 14 to remove mud from the artificial turf.

Here, "no contact" means that the remaining part of the artificial turf
Indicates that there is no lower part of the artificial turf that has been inverted to capture or collect mud that falls from the artificial turf.

The equipment e is shown. In this embodiment, the artificial turf 11 is
2 and then passes through an idle roller 21 and is wound around a take-up roll 26. In this embodiment, the portion of the path of the artificial turf 11 in which the turf material projects downwardly from the backing layer 13 extends from approximately the 8 o'clock position of the take-up roll 26 to approximately the 4 o'clock position of the take-up roll 26. Exists. Artificial grass 1 is placed on a rotating drum 46 disposed below the winding roll 26.
A tapping rod 47 is provided which engages with 1 and removes mud from there. In addition, in order to carry out the mud removed from the artificial turf 11,
It is preferable to use a chute 33 and a belt conveyor 34.
