As described above, a recycling sorting operation of the recycling sorting system according to an exemplary embodiment of the present invention will be described with reference to FIGS. 1 to 4.

First, the waste paper, bottles, iron flakes, fibers, plastics, styrofoam, cans, and large plastics brought in from the recyclable waste collection station are mixed in the recycled product hopper 130 of the storage unit 100. .

At this time, the large plastics are put into the crushed state in the plastic crusher 120 to facilitate the transfer and sorting operation.

Recycled products introduced into the recycled hopper 130 are mixed to the preliminary selection unit 300 by the transfer conveyor 200, and each of the recycled products transported on the preliminary selection unit 300. Convection, waste paper, fabrics, large waste, styrofoam are each sorted by the workers in each of the sorting storage tank (310).

At this time, the waste paper, styrofoam, and large waste contained in each sorting storage tank 310 are taken out to the outside in a compressed or crushed state by a waste paper compressor, a styrofoam container, and a large crusher, respectively.

In this way, the recycled products primarily selected in the preliminary selection unit 300 is transported by the conveying conveyor 200, the iron cans and iron pieces are sorted by the magnetic force of the iron can sorter 400 and the iron can compressor 410 Outside to be compressed.

After that, the iron cans and the iron pieces sorted by the iron can sorter 400 are introduced into the blower weight sorter 510 by a conveying conveyor 200, and the glass bottle and the small household electric current are sorted by the blowing, and the remaining recycled products. Are transferred to the wind selector 700.

The glass bottle and the small household electric current selected by the blower weight sorter 510 are introduced into the storage hopper 520 by the transfer conveyor 200, and the glass bottle and the compressed air are injected from the storage hopper 520. The small household current is transferred to the small household crusher 530 with foreign matters removed.

The glass bottle and the small household current transferred to the small household crusher 530 are transferred to the blown glass bottle sorter 540 through the conveying conveyor 200 in a state where only the small household current passes through the glass bottle.

The glass bottle transferred to the blown glass bottle sorter 540 and the small household current in the crushed state are sorted only by the glass bottle by the blowing, and the small household current is transferred to the recycling product hopper 130 of the storage tank by the conveying conveyor 200. And then re-screening.

In this way, the glass bottle selected by the blown glass bottle sorter 540 is introduced into the residual metal sorter 610 and is transported in a state in which the residual iron and aluminum attached to the glass bottle are removed as eddy currents, and the washing machine 620. After passing through the dryer 630, the color separator 650 is sequentially passed through the dryer 630 without being overlapped by the vibration feeder.

At this time, the air ejector 657 is operated in accordance with the color set in the vision controller 656 of each of the color sorter 650 while spraying compressed air to the glass bottle of the corresponding color glass on the alignment conveyor 651 The bottle is discharged to perform a glass bottle sorting operation for each color.

Thus, the glass bottles discharged for each color by the air ejector 657 of the color sorter 650 are stored in the glass bottle storage hopper 660 to be taken out to the outside.

On the other hand, the glass bottle and the small household current are introduced into the blower weight sorter 510 by blowing and the remaining recycled products transferred to the wind separator 700 are sorted by packaging films and vinyls by cyclone suction.

In addition, the recycled products in which packaging films and vinyls are sorted by the wind separator 700 are transferred to the eddy current sorter 800 by a transfer conveyor 200, and the plastics in the state where the residual iron and aluminum cans are sorted by eddy currents. The rotary separator 910 of the sorting unit 900 is transferred.

Here, the remaining iron cans and aluminum cans selected by the eddy current selector 800 are compressed by the iron can compressor 810 and the aluminum compressor 820, respectively, and then carried out to the outside.

The recycled products transferred to the rotary sorter 910 are sorted into small plastics such as light yogurt bottles and other large plastics by high-speed rotation.

The small and large plastics selected by the rotary separator 910 are transferred to the plastic electric feeder in a state of being compressed by the plastic press 920, respectively, to each plastic separator 940 in an unfolded state without overlap. Transferred.

When the plastic is transferred to the plastic separator 940 by the transfer conveyor 200, the sorting conveyor 941 connected thereto is transferred, and when the near infrared emitter 942 emits near infrared rays to the plastic, the reflected light is analyzed ( 943).

Then, the analyzer 943 operates the air ejector 944 so as to sort only the plastic of the corresponding input component, and discharges only the plastic, and sequentially transfers another plastic to the next plastic separator 940. .

In this way, the plastic selected by each component by the plastic separator 940 is stored in the plastic storage hopper 950 by a transfer conveyor 200 and then carried out in a compressed state by the plastic compression binder 960. do.

As such, the sorting of recycled products is easily performed by automatically selecting the color of the glass bottle and the sorting of plastic components.

As described above, the recycled product sorting system of the present invention provides an effect of shortening the recycled product sorting time by automatically sorting by color of the glass bottle and sorting of the plastic components by the color sorter and the plastic sorter.

As mentioned above, although this invention was demonstrated by the limited embodiment and drawing, this invention is not limited by this, The person of ordinary skill in the art to which this invention belongs, Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
