A Plastic Flakes Collection Compensation Device and Recycling Collection Compensation Method Using The Same}

The present invention relates to a plastic flake collection compensation apparatus and a method for collecting and compensating recycled products using the same, and more particularly, by crushing plastic waste including a waste PET bottle, which is a crushed object, to have a predetermined shape, thereby generating tradable plastic flakes, At the same time, it is a plastic flake collection compensation device capable of providing a predetermined compensation to the shredding object providing destination that provided the waste PET bottle, and a recycling product collection compensation method using the same.

Items that can be used among household wastes are mainly waste paper, glass bottles, cans, plastics, metals, clothes and other materials. Looking at the general route of collection of recyclables, recyclables separated and discharged from home by their own management network are transferred to the intermediate sorting center through vehicles, and the recyclables collected at the intermediate sorting center are sorted by item and then handed over to the recycling plant of the item for recycling. . Bottles are regenerated and made into bottles, plastics are produced as new products through a recycling process, and paper is used in different ways depending on the quality.

In particular, in the case of the plastic, in order to ensure the convenience of transportation, the plastic flakes flaked by crushing the plastic are transported to the recycling plant, and when the recycling process in the recycling plant is in progress, the plastic flakes are washed. .

At this time, there is a problem in that the efficiency of the regeneration process is slightly lowered as a large amount of plastic flakes having a specific gravity lower than that of water are lost during the cleaning process for the plastic flakes.

Meanwhile, as a way to improve the recycling rate of waste plastic resources such as PET bottles, a reverse bending machine (RVM) has been developed to compensate for the crushed object. In order to recognize various types of PET bottles, the barcode printed on the PET bottle is recognized to check the capacity, and according to the confirmed capacity of the PET bottle, a predetermined compensation is provided to the provider who provided the PET bottle. have.

However, in the case of the conventional RVM, which recognizes the above-described barcode to determine the capacity of a PET bottle, a vast amount of data on the barcode must be collected in advance, and if the barcode is damaged, it is difficult to check the capacity for the PET bottle. There was still a problem in that adequate compensation for providers was not performed smoothly.

In addition, the step of estimating the size of the object to be shredded (S500) is a step of estimating the size of the object to be shredded based on the point of the pixel change after the step of determining whether the pixel is changed (S400).

In particular, in the step of estimating the size of the object to be shredded (S500), an outline of the object to be shredded on the image to be analyzed is extracted based on a pixel change point of the image to be analyzed, and an estimated region ( It proceeds to generate the estimated target image I4 edited to hold S).

In this case, the estimation target image I4 is generated by deleting a predetermined range of the analysis target image I3, and the size of the estimation target image I4 is smaller than the size of the analysis target image I3. It is done.

In addition, by performing an operation on the number or size of pixels constituting the estimation target image, it is possible to grasp the capacity of the analysis target corresponding to the estimation target image.

In particular, by allowing the pixel change determination step (S400) and the shredding object size estimation step (S500) to be sequentially performed, the By detecting only the pixel change in the image of the object to be shredded, it is possible to estimate the size of the object to be shredded, so that the capacity of the object to be shredded can be quickly identified without pre-collecting a vast amount of information related to the object to be shredded corresponding to the barcode. do.

In particular, in the conventional case, in order to proceed with the analysis of one type of crushed object, at least 1,000 or more reference images were required, and thus a high-spec processor and a high-resolution photographing apparatus were required. However, in the case of the present invention, the outline of the input By acquiring only the information on the crushed object so that the capacity of the crushed object can be grasped, a high-spec processor and a high-resolution photographing device are not required, and thus, the cost required for size estimation of the crushed object can be significantly reduced.

In addition, the compensation step (S600) is a step of proceeding to provide a reward having a monetary value corresponding to the capacity of the shredding object according to the size of the shredding object after the estimating the size of the shredding object (S500).

In this case, the reward may include a voucher including at least one selected from a certificate, a coupon, a discount coupon, and a gift certificate, as well as points that can be exchanged for cash.

Each of the steps according to the present invention described above may be executed in a different order as necessary, and even in the case of an embodiment executed in such a way that the order is changed, it is natural that they belong to the scope of the present invention.

As described above, the present invention has been described with reference to the embodiments shown in the drawings, but this is only for explaining the invention, and for those of ordinary skill in the art to which the present invention belongs, various modifications or equivalents from the detailed description of the invention It will be appreciated that one embodiment is possible.

Therefore, the true scope of the present invention should be determined by the technical idea of the claims.
