Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste sorter for sorting various wastes and composts from construction wastes to leftover food in restaurants according to size.

[0002]

2. Description of the Related Art Conventionally, as a waste sorter of this type, there is a sorter of the present applicant (see Japanese Patent Laid-Open No. 4-176374). As shown in FIG. 6, a plurality of spiral bodies 63 are arranged in a plane in a frame opening 62 having a screen 61 for sorting small waste W1 stretched on the bottom surface, and driven to rotate toward the discharge side of large waste W3. The medium-sized waste W2 into the spiral body 6
It is dropped between Nos. 3 and 63 to send out what is on the screen 61 in the spiral advancing direction, which has been well received by construction waste processing companies.

[0003]

A rope, various cords, and tapes are mixed in the waste, and the spirals are wound around the spiral during the sorting operation, and the operation must be interrupted for removal. In addition, the screen may become clogged if leftover food or compost that is damp or wet is mixed in, and it may become impossible to separate fine particles such as earth and sand. The present invention solves the above-mentioned problems of the prior art, whether it is mixed with a wide range of waste materials from construction waste materials to leftover food from restaurants or compost from farmers, or is wet or wet. It is a large amount of material that is continuously sorted into two sizes without clogging, and if it is light, it can be fed in the direction of rotation of the rotor so that ropes, strings, or tape are not wrapped around it.
The purpose is to provide a sorting machine.

[0004]

To achieve the above object, according to the solution to ## selected by machine, mutual parallel and are substantially horizontally arranged toward the discharge side of the sorted large object from the input side, discharged from the supplying side It consists of multiple rotors that are driven to rotate in the same direction from side to side.Each rotor has irregularities on the peripheral surface and side surfaces so that adjacent ones are intertwined with each other.
In a sorting machine comprising a plurality of wheels with protrusions,
The unevenness of the peripheral surface of the ring body is different from the rotation direction of the rotor.
Formed from a number of fingers shaped projecting member which is curved in the rearward direction Te <br/> is, and each finger-like projecting member is less on one side <br/> surface thereof even so as not to interfere with the adjacent ones above It is characterized in that a plurality of protrusions are formed.

Further, if the rotor is composed of a square shaft and a plurality of ring bodies having square holes for fitting the square shaft and finger-like projections projecting from the periphery, the key can be omitted and the manufacturing cost can be reduced. , Easy to maintain. In addition, when the rotation of the rotor on the half of the charging side is made faster and the rotation of the remaining rotor on the discharging side is made slower, the particle size of the substance falling from between the finger-shaped projections is further divided into two types, that is, the particle size on the charging side. It can be divided into small ones and ones having a large particle size on the discharge side, and if air is blown from the lower side to the upper side of the rotor, the sheet and tape-like light ones can be more reliably separated and conveyed to the discharge side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A waste sorter as a representative embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a vertical sectional view of a waste sorter of the present invention, and FIG.
Fig. 3 is a partial horizontal sectional view taken along line II-II, Fig. 3 is an elevational view of the rotor body, Fig. 4 is a sectional view taken along line IV-IV in Fig. 3, and Fig. 5 is a finger of another embodiment. FIG. 3 is an explanatory view of a protruding member.

1 to 4, a waste sorter 1
Is a rectangular frame 10 erected on a belt conveyor C2 for carrying out small and medium-sized wastes W1 and W2, and the frame 1
4 parallel to each other in the same plane horizontally from the waste input side to the discharge side of the selected large waste W3 in four rows rotatably supported in the same direction (indicated by arrow A). .., a rotary drive device 30 for the rotors 20, ..., And a discharge part 16 for the large waste W3 in the rotation direction A.

Each rotor 20 has a square cross-section angular shaft 21 having a gear 33 fixed at one end and a square hole 25a fitted into the angular shaft 21 so that the rotor 20 and the adjacent ones interlock with each other. A ring body 25 made of hard rubber or soft plastic in which twelve finger-shaped projecting bodies 26 projecting backward on the peripheral surface are provided, and a spacing piece 2 provided between the ring bodies 25, 25.
And 8. The projecting body 26 has two hemispherical projections 26a,... Protruding on one surface, and the other surface is a flat surface. When the thickness of the spacing piece 28 is changed, the protrusion 26a,
... and the distance between the adjacent protrusions 26 are changed to obtain the same effect as just changing the size of the mesh of the sieve.

A conveyor C1 for introducing waste such as construction waste is connected to the input side of the frame 10, and a ramp way 16 for discharging large waste W3 is connected to the discharge side. The rotor 20 is supported by the bearing 11a on the outer side of the side wall 11, and the rotary drive device 3 is provided outside the side wall 11.
0 is set. The rotation driving device 30 includes a motor 31.
And a pinion gear 32 with an output shaft thereof, a rotor-equipped gear 33 meshing with the pinion gear 32, and an idler gear 34 between the adjacent rotor-equipped gears 33, 33. The four rotors 20, ...・ All are rotated in the direction of arrow A.

In the waste sorter 1 of the present embodiment, the air flowing to the discharge side is generated during operation, and if it is a light cassette such as a radio cassette tape, a video cassette tape, or a nylon string, it does not completely wrap around. It can be floated and discharged, and the bundle of ropes and wires can also be finger-like protrusions 26 and their protrusions 26.
It is inherited one after another and discharged. Further, even if wastes or other substances having a high water content are mixed in the waste W, they can be dropped downward without causing clogging, and this can be used for sieving compost. When the rotation of the rotor 20 is increased, the protrusion 26a and the protrusion 2 are relatively moved.
The sieve mesh formed by 6 and 6 becomes fine, and the mesh mesh becomes relatively coarse when the rotation is lowered. Furthermore, it is possible to continuously sort large amounts of construction waste, household waste, office waste, restaurant leftovers, etc. into two types of sizes with a structure that does not easily cause clogging or breakage. If the crushing process is performed before the waste is put into the sorting machine 1, the processing after sorting can be performed immediately.

In addition to the above embodiment, as shown in FIG. 5, protrusions 26'a and 26 "a are formed so as to be intertwined with each other on both side surfaces of the protrusions 26 'and 26" and to face each other. Alternatively, a trapezoidal key or a truncated cone projection can be formed instead of the hemispherical projection. In addition, the one in which the wheel body and the spacing piece are integrated is also used. In addition, the rotor 20 in the representative embodiment,
If the rotational speed of the two rows on the input side of ... is rotationally driven faster than the rotational speed of the two rows on the discharge side, the faster the rotation, the finer the gap between the finger-like protrusions becomes, and the more accurate the size of the sieve. The effect of making the eyes smaller can be obtained, and it is possible to separate into those having a small particle size on the input side and those having a large particle size on the discharge side. This is because of the high water content that could not be separated by a screen sieve (sand is usually difficult to sort if 10 to 15% or more), compost, food-related residues, and stones subjected to rainfall and dust-prevention watering. It is particularly effective for building material mixed waste such as bulk board powder. Furthermore, the rotor 20,
When air is blown upward from below under the air duct, it is possible to reliably send out paper scraps, plastic sheets, films, tapes, and other lightweight items to the unloading side.

[0012]

As described above, according to the waste sorter of the present invention, even if a wide range of wastes such as construction wastes, leftover foods of restaurants and composts of farmers are mixed, the wastes can get wet. Prevents clogging even if it is wet
It can be continuously sorted into a large amount of two sizes without arousal, and is floated by the wind generated by the finger-like protrusions that rotate so that light ropes, cords, and tapes do not wind around the rotor. Ru can be delivered.
