The present invention relates to a sorting apparatus for sorting and separating recycled products by type using wind power, in particular, the recycled products are classified into lightweight recycled products and heavy-weight recycled products using wind power, and are again included in the lightweight recycled products using frictional force of the wind power and the conveyor. The present invention relates to a recyclables sorting device using a two-stage conveyor that can sort plastic bottles more reliably.

In general, among the garbage generated at home or industrial sites, recycled materials such as paper, vinyl, plastic bottles, and glass bottles are sorted and collected, and then recycled for recycling through reprocessing. To prevent environmental pollution caused by garbage.

As described above, in order to recycle recycled materials and use them as resources, it is important to separate and collect the recycled materials accurately by type. However, in reality, the separate collection of recycled materials is not made correctly, and the recycled products are sorted by type using various sorting devices.

Meanwhile, conventionally used sorting apparatus is a windscreen sorting apparatus for sorting relatively light papers or vinyls using wind power, putting garbage into a drum having a plurality of perforated holes, and then using a centrifugal force by rotating the drum. Various sorting devices such as centrifugal force sorting device for sorting small waste and floating sorting device for sorting waste using the specific gravity difference of the waste by putting the waste in the water tank are used.

However, in the case of the conventional wind sorting device, it is simply a method of sorting the recycled products by the wind, so the relatively light plastic bottles are classified into the same type together with the vinyl or paper, so the accuracy of classification is not suitable. I have a problem.

In addition, in the case of the centrifugal force sorter, since the garbage is entangled in the drum, vinyl or the like is wound on the outside of the plastic bottle, and this also has a problem that is not suitable for sorting the plastic bottle.

In addition, the floating sorting device generates a difference in the sorting result according to the state of the plastic bottle discarded as waste. That is, when the air is filled in the plastic bottle, the plastic bottle is suspended in the water, while the water is filled in the plastic bottle sinks in the water has a problem that is not suitable for sorting the plastic bottle.

Due to the problems as described above, there is a problem in that the conventional sorting result is mixed with vinyl and plastic bottles together, so that a rework for reclassifying them is required.

The present invention has been made in consideration of the above problems, and an object of the present invention is to classify recycled products into light-weight recycled products and heavy-weight recycled products by using wind power, and again use plastic frictional streams included in light-weight recycled products by using friction force of wind power and conveyor. It is to provide a recycling sorting device using a two-stage conveyor to sort more reliably.

Another object of the present invention is to provide a recyclables sorting apparatus using a two-stage conveyor, which makes it possible to accurately sort the plastic bottles included in the recycled product.

Another object of the present invention is to provide a recyclables sorting apparatus using a two-stage conveyor to facilitate the sorting of the recycled products by type.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram of a sorting apparatus according to a preferred embodiment of the present invention.

Recycling material sorting apparatus of the present invention classifies the light recycled and heavy recycled by using the blower 110, and the plastic contained in the light recycled by using the upper conveyor 120 installed to have an inclination angle (A: shown in Figure 2) In order to reliably sort bottled water, it is comprised by the blower 110, the upper conveyor 120, and the lower conveyor 130. As shown in FIG.

The blower 110 is to provide a wind power for sorting and separating relatively lightweight recycled materials, such as paper, vinyl and plastic bottles included in the recycled products. On the other hand, in order to effectively sort the lightweight recycled products contained in the recycled products by wind power, it is preferable to apply the wind power in the state of free fall of the recycled goods, and the blower 110 is transported by the transport means 150 to freely fall recycled goods. It is disposed under the vehicle 150 to apply wind power. In this case, a known belt conveyor may be used as the transport means 150.

On the other hand, heavy recycled materials such as glass bottles or cans that are not affected by the wind power of the blower 110 are dropped as they are and are loaded in a separate place.

Figure 2 shows the configuration of the top conveyor according to the present invention.

The upper conveyor 120 is to sort the plastic bottle of the lightweight recycled goods blown by the wind, is disposed to be located in the front of the neighboring blower 110, the plastic bottle included in the lightweight recycled product is the direction of the rest of the lightweight recycled product It is provided in the structure which has inclination-angle A so that it may roll down in the opposite direction D` from (D). The upper conveyor 120 may be configured by a known belt conveyor, of course, it is operated by a drive motor not shown.

According to the structure of the upper conveyor 120 as described above, the lightweight recycled goods flying by the wind is blown away by a certain distance by the wind and inertia fall on the upper conveyor (120). At this time, the paper or vinyl with light and wide ground area with the upper conveyor 120 is carried over the upper conveyor 120 by the friction force between the wind and the upper conveyor 120, and is loaded in a separate storage, and is heavier and has a larger ground area than the paper or vinyl. This small plastic bottled stream is rolled down by the inclination angle A of the upper conveyor 120 in a direction D ′ opposite to the traveling direction D of the remaining lightweight recycled product, thereby sorting the plastic bottled bottle.

On the other hand, in order to enable the plastic bottle to roll down in the opposite direction (D ′) by the inclination angle (A) of the upper conveyor 120, the belt surface of the upper conveyor 120 is smoothly constructed or the PVC has a low coefficient of friction. By using a resin belt, the plastic bottle can be configured to roll down or slide down by the inclination angle (A).

In addition, the inlet side (120a) of the upper conveyor 120 is disposed close to the blower 110, to prevent the plastic bottled to roll back to the inlet side (120a) of the upper conveyor 120 to rise again by the wind. For this purpose, the inlet side 120a of the upper conveyor 120 is preferably disposed so as to be located away from the wind influence range R. The inlet side 120a of the upper conveyor 120 according to the present embodiment is disposed to be located at the lower end of the wind power range (R). According to this structure, the wind power generated from the blower 110 is injected in a direction that does not directly affect the upper conveyor 120, so that the plastic cocurrent flow down the upper conveyor 120 is not affected by the wind and the lower conveyor 130 ) Can be dropped.

On the other hand, the inclination angle (A) of the upper conveyor 120 is preferably to be adjusted by the user according to the sorting work object or sorting work volume. The inclination angle A of the upper conveyor 120 may be adjusted by installing the hydraulic cylinder 161 at the lower end of the upper conveyor 120. Of course, the end side of the inlet side 120a of the upper conveyor 120 which is not supported by the hydraulic cylinder 161 is hinged to the structure 160 installed to support the case 140 or the lower conveyor 130 which will be described later. Is installed to enable this.

Figure 3 shows a block diagram showing another structure of the upper conveyor according to the present invention.

The upper conveyor 120 may be configured by a combination of the first conveyor 121 and the second conveyor 122. At this time, the first conveyor 121 is disposed on the inlet side where the light recycled material is introduced, and the second conveyor 122 is disposed at a position adjacent to the first conveyor 121, and the first conveyor 121 and the second The conveyor 122 is provided so that the inclination angles A1 and A2 may be provided.

The first and second conveyors 121 and 122 allow papers and vinyls to pass over the first and second conveyors 121 and 122 of the lightweight recycled products blown by the wind, while the plastic bottles are rolled down on the second conveyor 122. Selecting the plastic bottle by means of the same function as the upper conveyor 120 described above.

However, when the upper conveyor 120 is constituted by the first and second conveyors 121 and 122, a faster sorting of the plastic bottle flow is formed by forming a gap 123 for discharging the plastic bottle flow between the first and second conveyors 121 and 122. There is an advantage that the processing becomes possible.

That is, the gap 123 formed between the first conveyor 121 and the second conveyor 122 provides a function of a passage through which the plastic bottle flow is supplied to the lower conveyor 130, and is light weight flying by wind power. It is formed so as to be located in a non-contact area where no contact with the recycled product is made. The non-contact area referred to herein means a portion where the light recycled goods moved by the wind and the conveyor are not in contact. In the case of the light recycled goods moved by the wind, they move a certain distance by the wind and the inertia. Therefore, a region is generated in which the conveyor and the light recycled material are not in contact, and the present invention defines this region as a non-contact region.

According to the first conveyor 121 and the second conveyor 122 having the structure as described above, the plastic bottle flow included in the lightweight recycled goods blown by the wind is a gap 123 formed between the first and second conveyors 121 and 122. The plastic bottle is dropped on the second conveyor 122, and the plastic bottle dropped on the second conveyor 122 is rolled down by the inclination angle A2 of the second conveyor 122, between the first and second conveyors 121 and 122. It is supplied to the lower conveyor 130 through the gap 123 formed in the. Of course, in the case of vinyl or paper, it is loaded in a predetermined place beyond the second conveyor 122.

Hydraulic cylinders (162, 163, 164) can be further installed at the bottom of the.

More specifically, in the case of the first conveyor 121, since the position of the inlet side should not be changed, the inlet side is hinged to the structure 160 supporting the case 140 or the lower conveyor 130 which will be described later. Installed in a rotatable structure, the hydraulic cylinder 162 is installed at the lower end of the opposite side of the inlet side can be configured to be able to adjust the inclination angle (A1) of the first conveyor (121).

In the case of the second conveyor 122, one or two hydraulic cylinders 163 and 164 may be installed at lower ends of both ends, respectively, to adjust the inclination angle A2.

Referring back to FIG. 1, the lower conveyor 130 receives and transports a plastic bottle that rolls down by the inclination angle A of the upper conveyor 120, and is installed at a vertical lower portion of the upper conveyor 120. The lower conveyor 130 is also composed of a belt conveyor, and is operated by a separate drive motor to carry the sorted plastic bottle.

On the other hand, since the sorting apparatus of the present invention classifies by type by applying wind power to the recycled product, it is preferable that the sorting process of the recycled product is made in the case 140 to prevent the recycled product from flying unexpectedly.

The lightweight recyclables sorting passage 143 is combined with the upper conveyor 120 to provide a passage through which lightweight recyclables blown by wind power are transported. This lightweight recycled sorting passage 143 is a corrugated pipe at both ends so that when the upper conveyor 120 is rotated to adjust the inclination angle (A) of the upper conveyor 120, the position can be moved together with the upper conveyor 120 ( 143a, 143b).

The conveying passage 144 is combined with the lower conveyor 130 to form a passage for conveying the sorted plastic bottle. The conveying passage 144 is formed in a structure in which the upper end of the inlet-side partial region is opened so that the plastic bottle flowing down the upper conveyor 120 can be supplied to the lower conveyor 130. Of course, when the upper conveyor 120 is composed of the first and second conveyors 121 and 122, the inlet-side partial region of the transport passage 144 and the upper portion of the partial region corresponding to the position of the gap 123 are opened. Is formed.

The weight recyclables sorting passage 145 is to provide a passage through which relatively heavy weight recycled products which are not affected by wind among free-fall recyclables are dropped as they are and loaded into a separate storage.
