Description

{Apparatus sorting Cushioning of Artificial Turf}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cushioning material sorting apparatus for artificial turf, and more particularly, to a cushioning material sorting apparatus for artificial turf that can easily separate chips and sand from cushioning materials of artificial turf.

Artificial turf is one of the specially used landscaping materials, and it is a substitute for artificial grass with lawn shape. It can be used in indoor gardens that have been used primarily for sports grounds since the first production in the United States and where the grass can not grow, or in outdoor areas such as the north side of tall buildings with limited sunshine hours.

Such artificial turf is always kept green and is not restricted by environmental conditions, so it is easy to manage after construction. The artificial turf field with artificial turf construction has a higher initial construction cost than general natural turf but is highly preferred due to its semi-permanent use, convenience of maintenance, and uniformity of surfaces for exercise. In artificial turf for sports, artificial turf was used as a means to absorb athlete's impact and to secure a series of appropriate playability, such as ball rolling, frying of the ball, speed change of the ball after the ball was bound to the ground .

Such artificial turf has evolved through various stages along with the development of the customer's demand and material technology. Especially, in the case of artificial turf for soccer field, the FIFA standard, which is a quality authentication system for artificial turf called 'FIFA quality concept' since 1990, has been introduced, and the demand for standardized competition has been increased. It is being tried.

FIG. 1 shows artificial turf for soccer field as an example of artificial turf. As shown in the figure, the artificial turf is composed of a fibrous bubble 1 laid on the ground 6 and a cushioning material filled between piles and piles formed on the fibrous bubble 1, A cushioning material consisting of a sand 5 and a rubber chip 4 is alternately formed between the piles 2 and 3 and the long piles 2 made of polypropylene and the short piles 3 made of polyamide are alternately formed It has a filled structure.

Typically, the cushioning material is a mixture of rubber chips 4 and sand 5 in a mass ratio of 40 to 50%: 60 to 50%. In general, synthetic grass is replaced after about 7 to 8 years. At this time, the cushioning material is buried or processed, or the rubber chip 4 is separated and recycled from the sand 5, but the recovery rate of the rubber chip 4 is low There is a problem that recycling is not efficiently performed because the recycling degree is low.

FIG. 2 is an elevation view showing an apparatus for sorting cushioning materials for artificial turf according to an embodiment of the present invention, and FIG. 3 is a side view of FIG. 2. The artificial turf cushioning material sorting apparatus 100 according to the embodiment of the present invention includes a support 110, a screening cylinder 120, a water supply unit 130, a vibrator 140, 150).

The support frame 110 is a frame for supporting the screening container 120 and includes a base frame 111 and vertical frames provided vertically upward in the middle of the base frame 111 for installing the water supply part 130 112). The base frame 111 is provided with a motor 161 for driving the vibrator 140.

The screening cylinder 120 is disposed on the upper side of the support frame 110 and is hinged to the support frame 110 through the swing connection part 150. [ The screening container 120 is in the form of a rectangular barrel having an upper edge and is made of stainless steel and is divided into a chip discharging portion 121, a sand discharging portion 122 and a separating portion 123. As shown in FIG. 3, the upper end of the screening tube 120 is bent inward to face each other to prevent water from splashing .

The chip discharging portion 121 is formed at one end (left side in FIG. 2) of the screening tube 120 and is a discharging portion of the chip. The discharging main body 121a is connected to the end of the separating portion 123, The discharge main body 121a is formed to protrude downward from an end of the separating portion 123. [ A guide passage 121b, through which chips are gathered and guided and discharged, is connected to the side of the chip discharging portion 121. A filter screen 121c for filtering and separating the chips from the water is installed in the lower side of the chip discharging unit 121.

The sand discharge portion 122 is formed at the other end (right side in FIG. 2) of the screening cylinder 120 and is a portion where the sand is discharged. The separating portion 123 is formed between the chip discharging portion 121 and the sand discharging portion 122 and is a portion where chips and sand are separated while moving in opposite directions. The bottom surface of the separating part 123 forms a separating slope 123a which is increased from the chip discharging part 121 to the sand discharging part 122. [

The bottom surface of the sand discharge portion 122 forms a discharge slope 122a having an inclination angle? 2 larger than the inclination angle? 1 of the separation slope 123a at the upper end of the separation slope 123a. The difference between the inclination angle 1 of the separation slope 123a and the inclination angle 2 of the discharge slope 122a is preferably 1 to 4 degrees.

The protruding protrusion 123b is formed at an end of the separator 123 on the side of the chip discharging portion so that the chip is transferred to the chip discharging portion 121 but the sand is not transferred to the chip discharging portion 121.

The water supply unit 130 is installed at the upper end of the vertical frame 112 of the support table 110 to supply water into the screening tube 120 in the middle of the screening tube 120. The water supply unit 130 is provided with a plurality of pipes 131 arranged along the longitudinal direction of the screening tube 120 so as to be adjustable in position, and has a control valve. The pipe 131 is made of a flexible hose, a metal pipe, or the like. The amount of water supplied according to the position of the pipe 131 is controlled by the control valve.

The vibrator 140 receives the rotational force from the motor 161 via the pulley and the belt and converts the rotational force into a linear motion through the hinge arm 142 to rotate the vibratory follower 120 attached to the bottom of the screen 120. [ And transmits the light to the screening unit 144 to vibrate the screening container 120. The hinge arm 142 is an arm of a crank mechanism that swings the hinge arm 142 once in forward and backward directions when the pivotal driving member 141 makes one rotation to move the screen 200 through the oscillating follower 144 . It is preferable that the vibration oscillation number (Hz) of the hinge arm 142 is adjusted to be 30 to 60 Hz. On the other hand, a separate vibrator may be attached to the bottom surface of the screen 200.

The first and second flanges 151 and 151 'protrude from both sides of the upper end of the base frame 111 and the links 152 and 152' are connected to the first flanges 151 and 151 ' 154 'are protrudingly formed on the bottom surface of the screen 120 and the second flanges 154, 154' are hinged by the first flanges 154, 153 ' The links 152 and 152 'are hinged by the hinge shafts 155 and 155'.

4 is a view showing a cushioning material sorting system in which the cushioning material sorting device of FIG. 2 is arranged. As shown in the figure, the raw material (cushioning material) in which the rubber chips and the sand are mixed is conveyed through the feed hopper 10 through the conveyor 20 (screw conveyor, etc.), on the upper side of the middle of the screening cylinder 120 of the cushioning material sorting apparatus 100 Water is supplied into the screening container 120 while water is supplied into the screening container 120 through the water supply unit 130. [

The screen 120 is vibrated to the left and right in accordance with the vibration of the vibrator 140 installed on the lower side of the screen tube 120 so that the sand having a larger specific gravity moves toward the sand discharge portion 122, The chip moves along with the water to the chip discharging portion 121 side. Since the sand is gray and the rubber chip is black, the sand and rubber chips move to form a different color band. As you see this colored band moving, you adjust the supply and frequency of the water.

The rubber chip moving along with the water toward the chip discharging portion 121 passes over the protruding protrusion 123b provided at the end of the separating portion 123 on the chip discharging portion 121 side, As shown in FIG. At this time, a part of the sand can move to the end (left end) of the separating part 123 but can not exceed the protruding step 123b, so that the rubber chip can be completely separated from the sand. The rubber chip moved into the chip discharging portion 121 is filtered by the filter screen 121c and discharged through the guide passage 121b to be collected in a chip container (not shown). The water is discharged to the lower end of the chip discharging portion 121 and stored in a water container (not shown), and the water in the water container is pumped by a pump (not shown) and recirculated to the water supply portion 130.

The sand moving from the separating section 123 to the sand discharge section 122 advances to the inclined angle? 1 of the separating section 123a of the separating section 123 and then the inclination angle? 1 of the discharge inclining section 122a of the sand discharge section 122 the inclination angle 2 of the discharge slope 122a is larger than the inclination angle 1 of the separation slope 123a so that the sand moves more slowly in the sand discharge portion 122 so that the rubber chip is sandwiched with the sand There is no case of being discharged. The difference between the inclination angle? 1 of the separation slope and the inclination angle? 2 of the discharge slope is preferably 1 to 4 degrees, Most preferred for separation.

The sand discharged through the sand discharge unit 122 is transferred to the discharge hopper 40 through the conveyor 30 (screw conveyor, etc.) and is stored or transported in the sand trap 50.

The amount of water supplied through the water supply unit 130 and the frequency of the vibrator 140 are controlled by the control unit 60. The inclination angle of the screen 120 can be adjusted through a slope adjusting mechanism (not shown).

The cushioning material discriminating apparatus 100 according to the present invention corresponds to a wet density sorter using water, and the yield of a rubber chip is improved by about 20% as compared with a conventional dry density sorter. A cushioning material having a mixing ratio of rubber chip and sand of 40 mass%: 60 mass% was used to perform screening tests at a vibrator frequency of 45 Hz. As a result, the yield of rubber chip in the dry mass sorter was only 80% According to the cushioning material sorting device (wet type sorter), the yield of the rubber chip was improved to 99.5%, and it was found that it was almost perfectly selected.

Fig. 5 is a photograph of a cushioning material sorting device of the present invention, which is used in the screening test of rubber chips, as seen from the rear side, of a manufactured sample for the cushioning material discriminating device 100 of Fig.
