Description

[0001] APPARATUS AND METHOD FOR TRASH SEPARATING [0002]

The following description relates to a separate collection device and a separate collection method.

In Korea, the amount of waste generated per unit area is very high at 3 OECD. 70% of the landfill wastes can be recycled as paper, plastic, and food, but in reality, these wastes are simply landfilled and resources are wasted. In addition, soil, groundwater, etc. are polluted due to various plastics and vinyls that are discarded indiscriminately.

In the conventional waste separation and collection system, the garbage is separated and discharged at home, the manpower directly separates the garbage from the garbage field, or the garbage is put into the machine and the garbage is collected through various processes. Because of these various processes, garbage disposal is very troublesome, and since the garbage separation and collection machine digests various processes, its size is very large as a small factory. If the manpower is directly separated (eg, the garbage bag is torn and put into the machine), there will be a lot of errors in the collection.

In order to reduce such inconvenience and error, it is necessary to worry about the technology that can separate garbage from home easily.

Hereinafter, specific embodiments will be described in detail with reference to the accompanying drawings. In addition, if it is determined that a detailed description of a related known configuration or a known function can obscure the gist of the embodiments, a detailed description thereof will be omitted.

On the other hand, the singular expressions include plural expressions unless the context clearly indicates singular value. And, when a particular section is referred to as "comprising ", it means that the particular section may include other configurations other than the specific configuration, as long as there is no specially contradictory description.

FIG. 1 is a view schematically showing the configuration of the separated collection apparatus 100 according to one embodiment. The separation and collection apparatus 100 according to the present embodiment includes a frame 110, a first classification unit 120, a metal detection sensor 125, a second classification unit 140, a sound sensor 145, (150, 160, 170, 180), and the like.

A slot 115 may be formed at one side of the frame 110. In this embodiment, the injection port 115 is formed on the upper surface of the frame 110. Alternatively, a slot 115 may be formed in the side surface of the frame 110. The trash is inserted into the frame 110 through the inlet 115 by the user. At this time, the infrared sensor 119 provided adjacent to the inlet 115 can detect whether or not the trash is inserted.

The inside of the frame 110 can be largely divided into three spaces. An upper space of the first rail 10, a space between the first rail 10 and the second rail 20, and a space below the second rail 20. A first sorting unit 120 can be connected to the first rail 10 and the first sorting unit 120 can run the first rail 10 by a known method. The second rail 20 may be provided below the first rail 10 and the second sorting unit 140 may run through the second rail 20. A plurality of garbage storage units 150, 160, 170, and 180 may be provided under the second rail 20. The charged garbage can be classified according to the material and accommodated in the garbage storage units 150, 160, 170, and 180.

The trash inserted into the frame 110 can be received in the first sorting unit 120 whose initial position is set below the inlet 115. A metal sensing sensor 125 may be provided inside or adjacent to the first sorting unit 120. In this embodiment, it is assumed that the metal detection sensor 125 is provided inside the first sorting unit 120. [ Alternatively, the metal detection sensor 125 may be provided outside the first sorting unit 120, for example, at a position corresponding to the initial position of the first sorting unit 120 in the first rail 10. In this case, the metal detection sensor 125 may be installed on the lower side of the first rail 10. The garbage contained in the first sorting unit 120 can be detected by the metal detection sensor 125, which may be exemplified by a proximity sensor or the like, whether the material is metal or non-metal.

FIG. 2 is a view showing the sorting of metal garbage of the separate collection and collection device 100 of FIG. Referring to FIG. 2, a description will be made of a process of the case where the input garbage is made of a metal material.

The control unit (not shown) may move the first sorting unit 120 to the first position if it is determined by the metal detecting sensor 125 that the waste contained in the first sorting unit 120 is made of metal such as a can . In FIG. 2, it is illustrated that the first position is the reference left side of the initial position of the first sorting unit 120. The running of the first sorting unit 120 on the first rail 10 by the control unit can be implemented by various known means, and thus a detailed description thereof will be omitted here.

Then, the control unit may open the first bottom plate (not shown) of the first sorting unit 120. The first bottom plate may selectively open and close the lower side of the first sorting unit 120, and the specific operation may be various, such as a sliding method, a rotating method by hinge coupling, and the like. As the first bottom plate of the first sorting unit 120 is opened, the garbage of the metal contained in the first sorting unit 120 can fall from the first sorting unit 120.

The dropped metal material waste can be guided to the metal garbage storage unit 150 side provided below the second rail 20 by the guide unit 130 having an oblique inclination. The metal garbage can be received and stored in the metal garbage storage unit 150.

Here, the compression bonding device 30 may reduce the volume of the metal garbage by compressing the metal garbage before the metal garbage is received in the metal garbage storage unit 150. In this embodiment, the compression device 30 is exemplified as including a pair of compression gears which are opposed to each other and rotate in opposite directions. The pair of presser shafts are rotated by a DC motor or the like, so that the waste of metal passing between them can be pressed.

FIG. 3 is a view showing a non-metal garbage sorting state of the separation and collection apparatus 100 of FIG. If the garbage received in the first sorting unit 120 by the metal detection sensor 125 is determined to be a non-metallic material other than metal, the process described below may be performed.

If the waste contained in the first sorting unit 120 is of a non-metallic material, the control unit may move the first sorting unit 120 to the second position and then open the first bottom plate. Here, the second position is exemplified as being the reference right side than the initial position of the first sorting unit 120. The non-metallic waste contained in the first sorting unit 120 can be dropped and accommodated in the second sorting unit 140 provided below the first rail 10.

The second sorting unit 140 can classify the received non-metallic waste into glass, plastic, and paper. For example, the impact sound generated when the non-metallic trash falls from the first sorting unit 120 and reaches the second bottom plate (not shown) of the second sorting unit 140 is detected by the second sorting unit 140, The sound sensor 145 provided adjacent to the sound sensor 145 can acquire the sound. The controller analyzes the obtained frequency of the impact sound to determine whether the received non-metallic waste is a glass material, a plastic material, or a paper material.

In this embodiment, it is assumed that the sound sensor 145 is provided on one side of the inside of the second sorting unit 140. Alternatively, however, the sound sensor 145 may be provided outside the second classification unit 140, for example at a point corresponding to the initial position of the second classification unit 140 in the second rail 20 . In this case, the sound sensor 145 may be installed on the lower side of the second rail 20.

For example, glass, plastic, and paper can be dropped in advance on a metal plate, and the frequency of the impact sound generated at that time can be analyzed. By repeating such preliminary work several times, the impact sound frequency band for each of glass, plastic and paper can be stored in a database in a form of a database. The control unit can determine the detailed material of the non-metallic waste by analyzing the frequency of the impact sound obtained by the sound sensor 145 and comparing the result with the stored frequency band.

As another example, glass in glass, plastic, and paper generates the hardest and largest impact sound, and through repetitive experiments, the boundary between impact sound frequency band for "glass" and impact sound frequency band for "plastic and paper" Can be calculated. The controller analyzes the frequency of the impact sound obtained by the sound sensor 145, compares the result with the boundary value, and determines whether the non-metallic waste is glass material or glass material. Also, it is also possible to obtain the impact sound frequency for the plastic by repeated experiment, store the lower limit value thereof, analyze the frequency of the impact sound obtained by the sound sensor 145, and compare the result with the lower limit value. The control unit can judge that the non-metallic waste is plastic material when the frequency analysis result value is lower than the lower limit value, and can judge that it is the paper material when the frequency analysis result value is lower than the lower limit value. This process can be useful when distinguishing lightweight papers from plastics with relatively low impact sounds.

For reference, the frequency analysis of the impact sound may be performed by a Fast Fourier Transform (FFT), and the separate collection apparatus 100 may include an FFT analyzer (not shown). The FFT analyzer may be provided as a separate device connected to the control unit, or may be in the form of an algorithm connected to or included in the control unit internal circuit and the processor.

FIG. 4 is a view showing a non-metal garbage classification of the separation and collection apparatus 100 of FIG. When the frequency of the impact sound between the non-metal garbage and the second classification unit 140 is analyzed, if it is determined that the non-metal garbage is made of glass, the control unit moves the second classification unit 140 to the third position, The glass waste can be stored in the glass waste storage part 160 by opening the plate. If it is determined that the non-metallic waste is plastic, the control unit moves the second sorting unit 140 to the fourth position and then opens the second bottom plate so that the plastic waste is accommodated in the plastic waste storage unit 170 . If it is determined that the non-metallic waste is paper, the control unit moves the second sorting unit 140 to the fifth position and then opens the second bottom plate so that the paper waste is accommodated in the paper waste storage unit 180 can do. FIG. 4 shows a situation where the non-metallic waste is plastic.

5 is a flow chart of the separate collection method according to one embodiment. Hereinafter, the separated collection method according to the present embodiment will be described with reference to FIG. Here, the separation and collection method may be performed in hardware in conjunction with the separation and collection apparatus 100 described above.

When garbage is charged through the charging port 115 of the frame 110 (S100), it can be determined whether or not the garbage is primarily made of metal (S200). To this end, the first sorting unit 120 in which the trash is received may be provided with a metal detection sensor 125.

If it is determined that the refuse is a metal material, the refuse of the metal material may be received and stored in the metal refuse storage through the pressing process (S210) (S220).

Alternatively, if it is determined that the garbage is a non-metallic material, a step of determining and classifying the detailed material of the non-metallic garbage may be performed (S300). As a specific example, garbage of a non-metallic material can be classified into any one of glass, plastic, and paper.

In order to classify non-metallic refuse, the non-metallic refuse is dropped (S310), and an impact sound generated upon falling can be obtained (S320). For example, non-metallic waste can be dropped from the first sorting unit 120 to the second sorting unit 140, and the non-metallic waste and the second bottom plate of the second sorting unit 140 may collide with each other The impact sound generated by the sound sensor 145 can be acquired. Subsequently, a frequency analysis for the obtained impact sound can be performed (S330). The frequency analysis can use Fast Fourier Transform (FFT) as described above. The detailed material of non-metallic waste can be judged by comparing frequency band of impact sound of glass, frequency band of impact sound of plastic, frequency band of impact sound of paper, and the result of frequency analysis.

Alternatively, in general, the size of the impact sound is glass-plastic-paper order, but a method of sorting the plastic after classifying the glass may be used. As a concrete example, it is possible to determine whether the non-metallic waste is a glass material by comparing the impact sound frequency for the previously stored "glass" with the impact sound frequency for the "plastic and paper" If it is a glass material, glass waste can be received and stored in the glass waste storage (S350).

If it is determined that the garbage of a non-metallic material is not a glass material, it may be determined whether the garbage is a plastic material (S360). It is possible to judge whether or not the non-metallic material is plastic by comparing the lower limit of the frequency with respect to the impact sound of the plastic obtained by the repeated experiment to the obtained impact sound. If it is a plastic material, plastic waste can be received and stored in the plastic waste storage (S370). If it is determined that the material is not a plastic material, it is recognized that the material is paper, and the non-metallic waste can be received and stored in the paper waste storage unit (S380).

Then, the residual capacity of the garbage storage unit of each material can be determined using an infrared sensor provided in the garbage storage unit of each material (S400), and the remaining capacity of the garbage storage unit can be transmitted to the user terminal through a wired or wireless communication method (S500). The user can adjust the processing schedule of the garbage storage unit while checking the remaining capacity information.

For example, the configurations or features described together in the specific embodiments may be implemented in a distributed manner, and the configurations or features described in each of the different embodiments may be implemented in a combined manner.
