5. The waste silicone cartridge recovery device of claim 1, further comprising a second return unit configured to return the waste item A determined not to correspond to the target for recovery by the second evaluation unit.
6. The waste silicone cartridge recovery device of claim 1, further comprising: a third evaluation unit configured to evaluate a quality of the waste item A based on the weight measured by the second evaluation unit when it is determined by the second evaluation unit that the waste item A is a material corresponding to a target for recovery; and a display unit configured to quantify and display the evaluation by the third evaluation unit into a score.
7. A waste silicone cartridge recovery method comprising: inputting a waste item A into a waste silicone cartridge recovery device; performing a first evaluation of determining whether the waste item A corresponds to a waste silicone cartridge, in the waste silicone cartridge recovery device; performing a second evaluation of measuring a weight of the waste item A determined to correspond to a waste silicone cartridge and determining whether the waste item A is a target for recovery; and evaluating a quality of the waste item A based on the measured weight of the waste item A, wherein the waste silicone cartridge comprises a high-density polyethylene (HDPE) and a silicon sealant, and wherein the performing the second evaluation comprises performing second machine learning of increasing accuracy of weight measurement of the waste item A through machine learning.
8. The waste silicone cartridge recovery method of claim 7, further comprising cutting the waste item A determined to be a target for recovery.
9. The waste silicone cartridge recovery method of claim 7, wherein the performing the first evaluation comprises: capturing an image of the waste item A using an optical camera; and performing first machine learning on the captured image to increase accuracy of the performing the first evaluation.
10. The waste silicone cartridge recovery method of claim 7, further comprising performing a first return of returning the waste item A determined not to correspond to the waste silicone cartridge in the performing the first evaluation.
11. The waste silicone cartridge recovery method of claim 7, further comprising performing a second return of returning the waste item A determined not to correspond to the target for recovery in the performing the second evaluation.
12. The waste silicone cartridge recovery method of claim 7, further comprising: performing a third evaluation of evaluating a quality of the waste item A based on the weight measured in the performing the second evaluation when it is determined in the performing second evaluation that the waste item A is a material corresponding to a target for recovery; quantifying the evaluation from the performing the third evaluation into a score; and providing a reward according to the score.

Description

[Technical Field] This application claims priority to and the benefit of Korean Patent Application No. 10-2023-0085892 filed in the Korean Intellectual Property Office on July 3, 2023 and Korean Patent Application No. 10-2024-0086646 filed in the Korean Intellectual Property Office on July 2, 2024, the entire contents of which are incorporated herein by reference. The present invention relates to a waste silicone cartridge recovery device and a waste silicone cartridge recovery method. [Background Art] Waste silicone cartridges are generated at construction sites. The waste silicone cartridge includes a high-density polyethylene (HDPE) and a silicone sealant, and the high-density polyethylene (HDPE) is a highly valuable material that can be used for various applications. However, there is a problem in recycling high-density polyethylene (HDPE) due to the silicone sealant with adhesiveness in the waste silicone cartridge. As a result, the waste silicone cartridges have been landfilled or incinerated rather than recycled. Therefore, after separately recovering the waste silicone cartridge, a process of removing the silicone sealant is required. That is, in recycling waste silicone cartridges, it is crucial to recover the waste silicone cartridges, and it is necessary to research methods for recovery. [Citation List] Korean Utility Model Application Publication No. 20-1995-022896 [Detailed Description of the Invention] [Technical Problem] The present invention is to provide a waste silicone cartridge recovery device and a waste silicone cartridge recovery method for increasing a recovery rate of a waste silicone cartridge.
