Description

Technical Field

[0001] The present invention relates to a waste polysiloxane cartridge recycling device and a waste polysiloxane cartridge recycling method.

[0002] This application claims the priority and benefits of Korean Patent Application No. 10-2023-0085892 filed with the Korean Intellectual Property Office on July 3, 2023, and Korean Patent Application No. 10-2024-0086646 filed with the Korean Intellectual Property Office on July 2, 2024, the entire contents of which are incorporated herein by reference. Background Art

[0003] Waste polysiloxane cartridges are generated at construction sites. The waste polysiloxane cartridges include high-density polyethylene (HDPE) and a polysiloxane sealant, and the high-density polyethylene (HDPE) is a very valuable material that can be used in various applications.

[0004] However, due to the adhesive polysiloxane sealant in the waste polysiloxane cartridges, there are problems in the recycling of high-density polyethylene (HDPE). Therefore, the waste polysiloxane cartridges are landfilled or incinerated instead of being recycled.

[0005] Therefore, after separately recycling the waste polysiloxane cartridges, a process for removing the polysiloxane sealant is required.

[0006] That is, when recycling the waste polysiloxane cartridges, the recycling of the waste polysiloxane cartridges is crucial, and a method for recycling needs to be studied.

[0023] Hereinafter, exemplary embodiments of the present invention will be described in detail so that those skilled in the art to which the present invention pertains can easily implement the present invention. However, the present invention can be implemented in various different forms and is not limited to the configuration described herein.

[0026] In this specification, "waste A" means waste of a waste polysiloxane cartridge expected to include high-density polyethylene (HDPE) and a polysiloxane sealant. Waste A is determined to be a waste polysiloxane cartridge or a waste polysiloxane cartridge equivalent to the recycling target by the waste polysiloxane cartridge recycling device and method described below.

[0027] In this specification, a "unit" means an interface that performs a specific function in a specific device.

[0028] In this specification, "the nth" is arbitrarily used to distinguish components with the same name and does not mean a limitation on the order unless otherwise specified.

[0030] Waste polysiloxane cartridge recycling method

[0031] Exemplary embodiments of the present invention provide a method for recycling waste polysiloxane cartridges, which includes: determining whether waste A corresponds to a waste polysiloxane cartridge, and determining whether waste A is a recycling target based on the weight of waste A determined to correspond to a waste polysiloxane cartridge. That is, the method for recycling waste polysiloxane cartridges according to the embodiments of the present invention has the following characteristics: Even if the waste is determined to be a waste polysiloxane cartridge, when the waste does not meet a certain weight standard based on the measured weight, the waste is not determined to be a recycling target.

[0032] In addition, in the step of determining whether waste A is equivalent to a waste polysiloxane cartridge and the step of determining whether waste A is a recycling target based on the weight of waste A determined to be a waste polysiloxane cartridge, using machine learning can improve the accuracy of the weight measurement of waste A.

[0033] Specifically, even if the waste determined to be a waste polysiloxane cartridge has the same weight, the content of high-density polyethylene (HDPE) may vary. However, considering the general structure of the waste polysiloxane cartridge, if a certain weight standard is met, it can be determined that the cartridge contains a sufficient amount of high-density polyethylene (HDPE) and has recycling value.

[0034] If any one of performing the first evaluation, performing the second evaluation, and the second machine learning unit is omitted, there will be a problem that the foreign matter in the waste polysiloxane cartridge cannot be effectively extruded. Therefore, the method for recycling waste polysiloxane cartridges of the present invention enables the effective extrusion of the sealant through the interaction of performing the first evaluation, performing the second evaluation, and the second machine learning unit.

[0035] That is, the present invention precisely sets the weight condition of the waste polysiloxane cartridge determined to contain a sufficient amount of high-density polyethylene (HDPE) and have recycling value through machine learning, thereby further improving the recycling value of the recycling target.

[0036] The method for recycling waste polysiloxane cartridges according to the embodiments of the present invention may further include a step of cutting waste A determined to be a recycling target. This can further contribute to the recycling of waste polysiloxane cartridges from waste A, and mainly remove unnecessary pollutants from waste A during the cutting process.

[0037] In the exemplary embodiment of the present invention, the step of cutting waste A can be performed using a cutter described below.

[0038] In the exemplary embodiment of the present invention, the step of performing the first evaluation may include: a step of capturing an image of waste A using an optical camera; and a step of performing machine learning on the captured image to improve the accuracy of performing the first evaluation.

[0039] Thus, by cutting waste A, the early curing of the internal sealant can be promoted and the transportation burden can be reduced.

[0040] In an exemplary embodiment of the present invention, the step of performing the second evaluation may include performing machine learning on the captured image to determine whether the waste A is a recycling target based on the weight, thereby improving the accuracy.

[0041] In an exemplary embodiment of the present invention, machine learning may use K-means, Support Vector Machine, or Convolutional Neural Network, but is not limited thereto, and various methods capable of improving the accuracy of the weight measurement of waste A can be used. The method cited as an example is a good way of using the image data obtained by capturing an image of waste A expected to be a waste polysiloxane cartridge. By adopting this method, it is possible to more easily determine whether the waste is a waste polysiloxane cartridge and determine the specifications of the waste polysiloxane cartridge, thereby improving the accuracy of the weight measurement of waste A.

[0042] The waste polysiloxane cartridge recycling method according to an exemplary embodiment of the present invention may further include a first return step of returning the waste A determined not to correspond to the waste polysiloxane cartridge when performing the first evaluation step.

[0043] The waste polysiloxane cartridge recycling method according to an exemplary embodiment of the present invention may further include a second return step of returning the waste A determined not to correspond to the recycling target when performing the second evaluation step.

[0044] The waste polysiloxane cartridge recycling method according to an exemplary embodiment of the present invention may include both performing the first return step and performing the second return step.

[0045] The returned waste article A can be separately collected and disposed of by landfill or incineration as usual.

[0046] The waste polysiloxane cartridge recycling method according to an exemplary embodiment of the present invention may further include performing a third evaluation step of evaluating the quality of waste A based on the weight measured when waste A is determined to correspond to the material of the recycling target when performing the second evaluation step; quantifying the evaluation from the third evaluation step into a score; and providing a reward according to the score. One of the purposes of the present invention is to improve the recovery rate of waste polysiloxane cartridges by providing appropriate rewards.

[0047] In this case, the step of quantifying the evaluation from the third evaluation step into a score can be performed based on the following formula 1.

[0048] [Formula 1]

[0049] P = W A *F A *P A

[0050] In Equation 1,

[0051] P represents the reward (amount),

[0052] W A represents the measured weight of waste A,

[0053] F A represents the evaluation ratio, and

[0054] P A represents the reward unit price (amount) per weight.

[0055] In an exemplary embodiment of the present invention, the evaluation ratio can be calculated according to the following Equation 2.

[0056] [Equation 2]

[0057] F A = 1 - C * │W A - W S │ / W S

[0058] In Equation 2,

[0059] F A represents the evaluation ratio,

[0060] C represents the allowable quality constant,

[0061] W A represents the measured weight of waste A,

[0062] W S represents the standard weight, and

[0063] │ │ represents the absolute value.

[0064] In this specification, the evaluation ratio refers to the ratio that can determine that the cartridge contains a sufficient amount of high-density polyethylene (HDPE) with recycling value under the condition of meeting a certain weight standard, considering the general configuration of the waste polysiloxane cartridge.

[0065] In this specification, the allowable quality constant refers to the value calculated by the user according to the allowable degree of foreign matter in the waste. Specifically, it refers to the reciprocal of the allowable foreign matter ratio in the waste.

[0066] In this specification, the standard weight refers to the weight used as a standard for determining the recycling target. In this specification, when it is determined that the measured weight of waste A, which is a waste polysiloxane cartridge, is equal to or greater than the standard weight, the waste is judged as a recycling target. When the measured weight of waste A is less than the standard weight, the waste is excluded from the recycling target because it indicates that the proportion of high-density polyethylene (HDPE) of the material obtained by the waste polysiloxane cartridge recycling method is low and contains a large amount of unnecessary materials such as polysiloxane sealant.

[0067] In an exemplary embodiment of the present invention, the standard weight may be 50 g, but is not limited thereto, and may be adjusted as needed.

[0068] In this specification, the allowable level of foreign matter in waste that affects the allowable quality constant can be quantified as the allowable foreign matter ratio.

[0069] Specifically, in an exemplary embodiment of the present invention, the allowable foreign matter ratio may be 10% or less, preferably 5% or less, but is not limited thereto, and the allowable foreign matter ratio may vary according to the purpose.

[0070] In an exemplary embodiment of the present invention, the allowable foreign matter ratio may be 2% or more.

[0071] Therefore, in an exemplary embodiment of the present invention, the allowable quality constant may be 10 or more, preferably 20 or more, and 50 or less.

[0072] In an exemplary embodiment of the present invention, │W A -W S │ / W S may be 0.02 or less.

[0073] The waste polysiloxane cartridge recycling method according to an exemplary embodiment of the present invention may further include a step of displaying the score. For this purpose, the above display unit may be used.

[0074] Figure 1 Shows the sequence of the waste polysiloxane cartridge recycling method according to an exemplary embodiment of the present invention.

[0075] As Figure 1As shown, first, waste A is placed into the waste polysiloxane cartridge recycling device. Next, it is determined whether the input waste A corresponds to a waste polysiloxane cartridge (first evaluation). In this case, an image of waste A is obtained by photographing it with an optical camera, and based on this, it is determined whether waste A corresponds to a waste polysiloxane cartridge. If it is determined that waste A corresponds to a waste polysiloxane cartridge, then the weight of waste A is measured to determine whether it exceeds the standard weight to determine whether the waste is a recycling target (second evaluation). In the case where it is determined that the measured weight of waste A exceeds the standard weight, waste A is cut and processed into a form suitable for recycling, and the quality of waste A is evaluated using the above method (third evaluation). Then, a reward is given to the person who collects waste A according to the set standard. When cutting waste A, the cutting unit described later can be used.

[0076] In this case, if it is determined in the steps of performing the first evaluation and the second evaluation that the waste does not correspond to a waste polysiloxane cartridge or is not a recycling target (the measured weight of waste A < standard weight), then the input waste A is returned.

[0077] In addition, as Figure 1 shown, if there is additional waste A to be input, the waste can be additionally input before the reward is provided. The additionally input waste A can also be rewarded or returned through the evaluation as described above.

[0078] Waste polysiloxane cartridge recycling device

[0079] Exemplary embodiments of the present invention provide a waste polysiloxane cartridge recycling device, which includes an evaluation unit that determines whether the waste A is a recycling target based on the weight of waste A determined to correspond to a waste polysiloxane cartridge. That is, the waste polysiloxane cartridge recycling device according to the exemplary embodiments of the present invention has the following characteristics: Even if the waste is determined to be a waste polysiloxane cartridge, when the waste does not meet a certain weight standard based on the weight, the waste is not determined to be a recycling target. That is, the waste polysiloxane cartridge recycling device according to the exemplary embodiments of the present invention corresponds to a device capable of performing the above waste polysiloxane cartridge recycling method.

[0080] Therefore, for the waste polysiloxane cartridge recycling device according to the exemplary embodiments of the present invention, it is important to determine whether the input waste corresponds to a waste polysiloxane cartridge, and even when the waste corresponds to a waste polysiloxane cartridge, to determine whether the waste corresponds to a recycling target.

[0081] For this purpose, as described above, machine learning can be used to determine whether waste A corresponds to a waste polysiloxane cartridge and to improve the accuracy of the weight measurement of waste A.

[0082] As described above, in an exemplary embodiment of the present invention, machine learning may use K-means, support vector machines, or convolutional neural networks, but is not limited thereto.

[0083] The waste polysiloxane cartridge recycling device according to an exemplary embodiment of the present invention may further include a cutting unit for cutting waste A determined to be a recycling target.

[0084] In an exemplary embodiment of the present invention, the cutting unit may include: a waste receiving unit for receiving waste A; a cutting tool for cutting waste A stored in the waste receiving unit; and an insertion unit inserted into the waste receiving unit to move waste A toward the cutting tool.

[0085] Figure 2 Schematically shows a cutting unit according to an exemplary embodiment of the present invention. As Figure 2 shown, the cutter 100 includes: a waste receiving unit 30 for receiving waste A which is a waste polysiloxane cartridge and determined to be a recycling target; a cutting tool 10 capable of cutting waste A along one axis or two or more axes; and an insertion unit 20 for moving waste A toward the cutting tool 10.

[0086] That is, the insertion unit 20 may be provided in such a form that it can be inserted into the waste receiving unit 30 to assist in cutting waste A and discharging waste A after cutting waste A.

[0087] That is, the insertion unit 20 pushes waste A input to the waste receiving unit 30 toward the cutting tool 10, so that waste A is cut along one or two or more axes. When waste A is continuously pushed toward the cutting tool 10, the cut waste A is discharged from the waste receiving unit 30. In addition, in this process, contaminants present on the surface of waste A can also be removed.

[0088] In an exemplary embodiment of the present invention, the cutting tool may be a band saw, a wire saw, or a circular saw, but is not limited thereto, and any tool capable of cutting a waste polysiloxane cartridge can be used without limitation.

[0089] In an exemplary embodiment of the present invention, the first evaluation unit may include: an optical camera for capturing an image of the input waste A; and a first machine learning unit for performing machine learning on the captured image to improve the determination accuracy of the first evaluation unit. That is, machine learning of the first evaluation unit is performed through the image.

[0090] The waste polysiloxane cartridge recycling device according to an exemplary embodiment of the present invention may further include a first return unit that returns waste A determined by the first evaluation unit not to correspond to the waste polysiloxane cartridge. As described above, waste A is waste expected to be a waste polysiloxane cartridge containing high-density polyethylene (HDPE) and a polysiloxane sealant, and may be waste other than the waste polysiloxane cartridge. In this case, recycling the waste A exceeds the purpose of the present invention, and accordingly, the waste A is not recycled but returned.

[0091] The waste polysiloxane cartridge recycling device according to an exemplary embodiment of the present invention may further include a second return unit that returns waste A determined by the second evaluation unit not to correspond to the recycling target. Even when waste A is determined to be a waste polysiloxane cartridge, if the weight of the waste does not exceed a certain weight, the recycling value is very low. That is, since the content of high-density polyethylene (HDPE) substantially recovered from the waste polysiloxane cartridge is too small, it may be more economical not to recycle the waste.

[0092] In addition, the waste polysiloxane cartridge recycling device according to an exemplary embodiment of the present invention may include both a first return unit and a second return unit.

[0093] The waste polysiloxane cartridge recycling device according to an exemplary embodiment of the present invention may further include a third evaluation unit that evaluates the quality of waste A based on the weight measured by the second evaluation unit when waste A is determined by the second evaluation unit to be a material corresponding to the recycling target; and a display unit that quantifies and displays the evaluation of the third evaluation unit as a score.

[0094] In an exemplary embodiment of the present invention, the third evaluation unit performs the evaluation by multiplying the weight of waste A determined to be a waste polysiloxane cartridge by a prescribed ratio. Based on the evaluation of the third evaluation unit, an appropriate reward can be given to a person who wishes to recycle waste A. The reward can be executed based on the above formulas 1 and 2.

[0095] That is, in an exemplary embodiment of the present invention, the first evaluation unit performs the above first evaluation, the second evaluation unit performs the above second evaluation, and the third evaluation unit performs the above third evaluation.

[0096] The description of the waste polysiloxane cartridge recycling method according to the present invention can be applied to the waste polysiloxane cartridge recycling device according to the present invention, and vice versa.

[0099] Specifically, a method for regenerating a waste polysiloxane cartridge is provided, which removes a polysiloxane sealant from the waste polysiloxane cartridge and obtains high-density polyethylene (HDPE).

[0100] That is, exemplary embodiments of the present invention may use a typical method for regenerating a waste polysiloxane cartridge, except that a waste polysiloxane cartridge recovered by a waste polysiloxane cartridge recovery method or a waste polysiloxane cartridge recovery apparatus according to the present invention is used.
