[Figure 9] FIG. 13 is a perspective view of an infill material treatment device for artificial turf in another embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The details of the infill treatment device 10 for artificial turf according to the present invention will be described below with reference to the accompanying drawings.

[0016] As shown in Figures 1 and 2, the infill processing device 10 for artificial turf has a machine direction MD and a cross direction CD perpendicular to the machine direction MD, and has a scraping-out process S1 for removing infill 2 consisting of sand 3, rubber chips 4, etc. from the artificial turf 1, and a sorting process S2 located downstream of the scraping-out process S1 for sorting the sand 3 and the rubber chips 4.

[0017] The "artificial turf" in the present invention is not necessarily limited, but may be, for example, a synthetic resin base fabric having a thickness of 0.1 to 2 mm, on the surface of which piles having a height of 10 to 80 mm are planted, and the back surface of the synthetic resin base fabric is coated with a rubber layer having a thickness of 0.1 to 3 mm, and the pile surface is subjected to a load of 10 to 30 kg / m. 2 This includes sand-filled artificial turf filled with sand with a particle size of 0.1 to 1.0 mm.

[0018] A pile having a height of 10 to 80 mm is planted on the surface of a synthetic resin base fabric having a thickness of 0.1 to 2 mm, and a rubber layer having a thickness of 0.1 to 3 mm is coated on the back surface of the synthetic resin base fabric, and the pile surface is subjected to a load of 20 to 35 kg / m 2 The sand is filled in the range of 5 to 15 kg / m2 and rubber chips with a particle size of 1.0 to 3.0 mm are filled in at a rate of 5 to 15 kg / m2. 2 The artificial turf may be filled with rubber chips and sand in the range of 100 to 200 mm.

[0019] The relationship between the sand 3 and rubber chips 4 that make up the filler 2 can be in various forms, such as a rubber chip layer layered on a sand layer, a sand layer layered on a rubber chip layer, sand layers and rubber chip layers layered alternately, or a mixed layer of sand 3 and rubber chips 4.

[0020] <Scraping process> Referring to Figures 3 to 6, the scraping process S1 includes a roller stand 20 for placing the artificial turf roll 1a that has been wound up in roll form from a sports field or the like, and a scraping device 30 located downstream of the roller stand 20 for scraping out the infill material 2 from the artificial turf 1.

[0021] 3 and 4, the roller stand 20 has legs 21 having wheels 21a, and a roller support 22 located above the legs 21. The roller support 22 has a plurality of rollers 25 extending in the cross direction CD and spaced apart from each other in the machine direction MD.

[0022] The roller 25 of the roller support 22 has a pair of upper rollers 25a, 25b and a plurality of lower rollers 25c arranged between the upper rollers 25a, 25b. Between the upper rollers 25a, 25b and the lower roller 25c, an arrangement space 8 is formed for arranging the rolled up artificial turf.

[0023] 3 and 5, the scraping device 30 has a leg frame 31 having wheels 31a, and a scraping mechanism 32 located above the leg frame. The scraping mechanism 32 has a rotating brush 33, a pair of upper and lower retraction tooth rollers 34, 35 for retracting the artificial turf 1 toward the rotating brush 33, and drive means 36, 37 consisting of a motor and a belt for rotating and driving the rotating brush 33 and the retraction tooth rollers 34, 35.

[0024] In addition, below the scraping mechanism 32, a first conveyor belt (conveyor means) 71 is positioned for conveying the sand 3 and rubber chips 4 scraped out from the artificial turf 1 by the rotating brush 33 in the machine direction MD. The conveyor belt 71 optionally has wheels 71a.

[0025] The scraping device 30 is equipped with guide means 60 for guiding the artificial turf 1. The guide means 60 has a guide plate 61 for guiding the artificial turf 1 from the roller stand 20, a guide and hold-down roll 62 located above and facing the guide plate 61, and a guide rod 63 extending in the cross direction CD parallel to the rotating brush 33 for guiding the artificial turf 1 that has passed between the retraction tooth rollers 34, 35 and the rotating brush 33.

[0026] The operation of the scraping process S1 will be described with reference to FIG. 6. First, a worker winds up the artificial turf 1 collected from a sports field or the like into a roll, places it on the forks 6 of a forklift 5, and moves it in front of the roller stand 20.

[0027] Next, with the power to the scraping device 30 turned off, the worker grasps the end of the artificial turf roll 1a and, guided by the guide plate 61 and the guide and holding roll 62, inserts it between the retractable tooth rollers 34, 35 and the rotating brush 33 with the pile surface of the artificial turf 1 facing the rotating brush 33.

[0028] Furthermore, the end of the artificial turf 1 is turned over and pulled upstream while being guided by the guide rod 63 , and passed through the legs 21 of the roller base 20 as it is, and then pulled out of the roller base 20 .

[0029] Next, the artificial turf 1 that has been pulled out of the roller stand 20 is wound around an electric winding roller 7 with a rotary motor that is disposed on the forks 6 of a forklift 5 .

[0030] In this state, by turning on the power to the scraping device 30, a force is applied to the artificial turf 1 by the electric winding roller 7, pulling it in the direction of arrow P1, so that the unprocessed artificial turf roll 1a located in the placement space 8 of the roller stand 20 is unfolded and the artificial turf 1 is unwound by the rotating roller 25.

[0031] The artificial turf 1 moves in the machine direction MD, and the brush of the rotating brush 33 penetrates into the pile surface of the artificial turf 1 between the retraction tooth rollers 34, 35 and the rotating brush 33. The rotating brush 33 rotates in the opposite direction to the rotation direction of the retraction tooth rollers 34, 35, and the brush penetrates into the pile surface of the artificial turf 1 and scrapes out the infill material 2 made of sand and rubber chips. The scraped out infill material 2 falls onto the first conveyor belt 71 located below the rotating brush 33.

[0032] The rotating brush 33 rotates at 300 to 600 revolutions per minute, and the brushes 33a of the rotating brush 33 preferably have a length dimension greater than the thickness dimension of the pile surface of the artificial turf 1, and may be composed of a plurality of comb-shaped portions with different lengths. In order to make it easier to scrape out the infill material 2, the brushes 33a may be provided with a plurality of protrusions, and the tips may be radial.

[0033] <Separation process> 7 and 8, the sorting step S2 includes a sorting device 40 having a mesh-like rotating drum 50. The sorting device 40 has legs 41 and 42 having wheels 41a and 42a, the rotating drum 50 that is rotated by a driving means 44 consisting of a motor and a driving belt, and a drum support frame 43 that supports the rotating drum 50.

[0034] The rotating drum 50 is hollow and has a first opening 51 located on the upstream side and a second opening 52 located on the downstream side, and an end 71b of the first conveyor belt 71 enters the rotating drum 50 through the first opening 51.

[0035] In the separating device 40, the leg 41 located on the upstream side is designed to be longer than the leg 42 located on the downstream side, and the separating device 40 has a shape that is inclined downward toward the downstream side. As a result, the rotating drum 50 is also arranged in a manner that is inclined downward toward the downstream side.

[0036] The mesh of the rotating drum 50 is large enough to allow sand with a particle size of 0.1 to 1.0 mm to pass through, but not rubber chips with a particle size of 1.0 to 3.0 mm. Therefore, as the rotating drum 50 rotates, only the sand 3 of the filler 2 passes through the mesh and is shaken down. Meanwhile, the rubber chips 4 are left inside the rotating drum 50.

[0037] Below the rotating drum 50 is a second conveyor belt (conveyor means) 72 extending at an upward gradient from the upstream side to the downstream side, and above the second conveyor belt 72 is a third conveyor belt (conveyor means) 73 positioned opposite the second opening 52 of the rotating drum 50 and extending at an upward gradient from the upstream side to the downstream side like the second conveyor belt 72.

[0038] A lower opening 46 is located on the lower surface of the drum support frame 43 facing the rotating drum 50. The second conveyor belt 72 has wheels 72a as an option. The third conveyor belt 73 is detachably fastened to the drum support frame 43 via a hook, but may have wheels like the first and second conveyor belts 71, 72.

[0039] The filler 2 transported by the first transport belt 71 moves into the rotating drum 50, where it is separated into sand 3 and rubber chips 4. Specifically, the sand 3 having a particle size smaller than the mesh of the rotating drum 50 is shaken off so as to pass through the mesh, passes through the lower opening 46 of the drum support frame 43, and falls onto the second transport belt 72.

[0040] Since the rotating drum 50 has a downward gradient toward the downstream side, the rubber chips 4 left inside the rotating drum 50 move downstream and onto the third conveyor belt 73 through the second opening 52 .

[0041] The sand 3 that has fallen onto the second conveyor belt 72 is transported in the machine direction MD by the second conveyor belt 72 and stored in a first storage bag 81. On the other hand, the rubber chips 4 that have been transported in the machine direction MD by the third conveyor belt 73 are stored in a second storage bag 82 placed on a placement table 83.

[0042] In this way, according to the infill processing device 10 for artificial turf of the present invention, the roller stand 20 and scraping device 30 that constitute the scraping process S1, and the sorting device 40 and transport means 71, 72, 73 that constitute the sorting process S2 are each configured as separate entities, so that these devices can be loaded onto a large truck or trailer, etc., and taken directly to locations where artificial turf is laid, such as tennis courts or soccer fields, to scrape out and sort the infill 2.

[0043] Therefore, compared to using built-in equipment installed at waste disposal sites, etc., the effort and cost of transporting the artificial turf by vehicle can be significantly reduced.

[0044] Furthermore, compared to running a conventional cleaning vehicle with the function of removing the filler 2, the treatment can be completed in a short time, and the filler 2 can be separated on-site, which is not possible with conventional cleaning vehicles, so that the separated sand 3 and rubber chips 4 can be immediately transported to separate treatment plants.

[0045] In addition, since the roller stand 20, scraping device 30, sorting device 40, and first and second conveying belts 71, 72 each have wheels as an option, the artificial turf filling material processing device 10 can be easily set up and removed.

[0046] 9 is a perspective view of an infill treatment device 10 for artificial turf in one example of the embodiment, and in this embodiment, the treatment operation is performed with the scraping device 30 constituting the scraping process S1 placed on the loading platform 91 of a truck 90. ​​In addition, an electric winding roller 92 for winding up the artificial turf 1 after the infill 2 has been scraped out is located below the roller stand 20.

[0047] In this embodiment, the scraping device 30 can be operated without having to be removed from the bed 91 of the truck 90, eliminating the need for laborious installation and removal and improving workability.

[0048] In the illustrated example, only the scraping device 30 is placed on the bed 91 of the truck 90, but the entire scraping process S1 including the roller stand 20, or the entire artificial turf infill processing device 10, can also be carried out while being placed on the bed of a large truck.

[0049] Unless otherwise specified, each of the constituent materials constituting the artificial turf filling material processing device 10 in the storage shelf 1 of the present invention can be any of various well-known materials commonly used in this type of field without any restrictions.
