Description

The present invention relates to a method for cutting an artificial laying material, which is performed when an artificial turf laid on a baseball field, a schoolyard, or the like, or an artificial laying material such as a carpet is removed for replacement, and the like. cutting apparatus and belongs to the technical field of the jig to, and more, the artificial laying thereof can speed cutting by adopting a forklift as traveling means, a very excellent workability and economy The present invention relates to a high-speed cutting method, a high-speed cutting device, and a jig for an artificial laying object such as artificial turf.

Artificial turf is more demanding in recent years because it is maintenance-free and superior in durability and aesthetics compared to natural turf, and is often used in various athletic stadiums such as baseball fields, school grounds, field stadiums, and ball game courts. in use.
However, although artificial turf is excellent in durability, damage due to natural deterioration or wear is inevitable, and it is necessary to replace it with a period of about 5 to 10 years. Even if it is not damaged, it is necessary to frequently replace artificial turf in dome-like facilities according to various athletics and concerts.

In this artificial turf replacement work, conventionally, the most labor-intensive and time-consuming work is the artificial turf cutting work. Conventionally, an operator operates a so-called concrete cutter to cut the artificial turf into a size suitable for removal and collection work.
However, in the cutting work using the concrete cutter, the artificial turf can only be cut at a low speed traveling capacity suitable for cutting concrete, for example, at a speed of about 1 to 2 m per minute, and the workability is very poor. There was a problem. Moreover, since the artificial turf on the laying surface such as a concrete floor, a wooden floor or the like on which the artificial turf is laid is directly cut with a concrete cutter, there is a problem that the laying surface is damaged. Furthermore, since the concrete cutter simply cuts the artificial turf on the laying surface, there are few clues for the work of peeling off the artificial turf that is bonded to the laying surface, which makes it difficult to remove.

By the way, in Patent Document 1, when cutting (cutting) the artificial turf in the laid state, after floating the cut portion of the artificial turf from the floor (laying surface), the floating portion is cut using a cutter. An artificial turf cutting method is disclosed (see claim 1 of the document 1). In addition, it has a mechanism for slightly lifting the laid artificial turf, a disk cutter, and a self-propelled mechanism that can move forward while cutting, and these mechanisms are provided on one side of the main body having a drive mechanism, and cut artificial turf An apparatus is disclosed (see claim 5 of the document 1).
According to the technique according to Patent Document 1, since the artificial turf raised from the laying surface is cut using a cutter, the problem of damaging the laying surface of the artificial turf has been solved.

Japanese Patent Laid-Open No. 7-158209

According to the technique according to Patent Document 1, there are the following problems.
(1) From the description of FIG. 1 of the document 1, the self-propelled function is assumed to be a commercially available large cutter device such as a concrete cutter. Further, since the gripping portion is provided above the rear portion of the self-propelled mechanism, it is recognized that the operator performs the cutting operation by maneuvering while following the walking. As a result, the artificial turf can only be cut at a speed of about 1 to 2 meters per minute, and the problem of poor workability remains. On the left of the proof, in the 7th to 8th lines of paragraph [0013] of the document 1, a description “cut into about 1 m square at a speed of 2 m / min” is recognized.
(2) Due to the problem of (1), the process of replacing the vast artificial turf laid in a baseball field, a field stadium, etc. depends on the slow progress of the artificial turf cutting operation, There was a problem that it was not uncommon for the cutting work to take several days. On the left side of the document, in paragraphs 8 to 9 of paragraph [0013] of the document 1, it is recognized that “cutting was performed over 2 days with a total length of about 1,000 m”.
(3) Next, since the technique of the literature 1 must firmly and accurately fix the artificial turf lifting mechanism 2 to the cutter device, the artificial turf lifting mechanism 2 is surely attached to the cutter device every time a cutting operation is performed. There is a problem that it is necessary to perform a process of attaching to the head, and this work is troublesome and the cost is increased.
(4) Furthermore, in the apparatus of the literature 1, the tip of the artificial turf lifting mechanism 2 is positioned behind the front wheel 3 of the self-propelled mechanism (see FIG. 1 of the literature 1), so that it is pressed by the wheels 3. Since the artificial turf lifting mechanism 2 forcibly removes the nearby artificial turf from the laying surface, the artificial turf lifting mechanism 2 is forced to perform an unreasonable operation, so that there is a problem that resistance during forward traveling is large and high-speed cutting is difficult.
