Description

Segregated Collection Apparatus of Recycled Product

The present invention relates to an apparatus for separating and collecting recyclables, and more particularly, in the process of automatically classifying the types of recyclables by recognizing recyclable resources as images, etc. It relates to a recyclable product separation and collection device capable of discharging foreign substances such as defective resources by rotating the pulverizing unit in reverse.

Various industrial products are being produced through mass production according to industrialization, and through the mass consumption of such industrial products, the discharge of household and industrial waste is explosive, and the amount of such waste is increasing every year. The amount of garbage in modern society is too large to be treated by nature's self-cleaning action. In particular, garbage that has undergone industrial processing such as cans and plastics takes a considerable amount of time to degrade naturally. Efficient disposal of substances, such as generation, is being discussed as a major environmental problem around the world.

In order to reduce the amount of waste and virtuous cycle limited resources, countries and local governments around the world encourage and make recycling mandatory. In particular, plastics and cans can be reused through a certain treatment process, and are representative recyclables. Recyclables are generally separated by recyclables by a self-management network at home, transferred to an intermediate sorting center through vehicles, etc.

However, if recyclables are separated and managed through a self-management network at home, recyclables collection containers are not managed, and there are problems such as mixing of general waste other than recyclables. However, the conventionally developed recycling collection device has a large volume, and when foreign substances are caught due to a malfunction during the collection process, they must be directly removed through manpower. There are various risks, such as the occurrence of various industrial accidents.

The present invention is to provide a recycling product separation and collection device for automatically sorting and storing resources to be recycled. , a crushing unit 60 , a storage unit 70 and a control unit 80 .

As described in the background art, recyclables refer to plastics, cans, and the like, which can be virtuously cycled among resources that are used and discarded in order to reduce the amount of waste and circulate resources. The term "resource" used in this specification refers to being a candidate for recycling because it is determined that a virtuous cycle is possible among wastes that are used and thrown away. Resources are recyclables such as plastics or cans if the user accurately judges them. However, there is an error in human judgment, and not everyone is aware of the standards for recyclables. Resources can be mixed. In particular, even in recyclable plastic or can containers, depending on use, defective resources that cannot be recycled may be mixed therein. Hereinafter, how to classify and pulverize plastics and cans, which are representative objects of recyclables, and defective resources that cannot be recycled are described.

As shown in FIG. 1 , the main body 10 has an inlet 11 formed at the upper portion so that resources are put in, so that it becomes a case of a recycling equipment separation and collection device. The main body 10 protects the device and the main body 10 ), different components of the device can be installed, so that the separation and collection device can be installed efficiently in a limited space. It may be generally formed in a rectangular parallelepiped shape, and may be installed in a place where many people come and go or a lot of resources that are candidates for recycling are generated. Specifically, it may be installed in the form of a vending machine in an apartment house, a large mart, or a government office. The inlet 11 formed on the upper portion of the main body 10 is a place to put the resource, and may be formed in a circular shape to correspond to the general shape of the resource. In addition, a door 12 may be formed in the inlet 11 to prevent an accident from occurring due to the user's hand, etc., while sorting the resource through the separation and collection device, and the door 12 When the input unit 20 is rotated through the classification unit 40 to be described later, the rotated input unit 20 may be formed to be opened only in a pushing manner so that the door 12 is not opened by blocking it. In addition, the upper end of the main body 10 may be formed in a structure that opens and closes to manage internal components, and the lower end of the main body 10 is formed in a structure that can withdraw the storage unit 70 to be described later for storing the classified resources. can

The input unit 20 moves the resource that has entered through the inlet 11 of the main body 10 to a predetermined position so that the recognition unit 30 to be described later can recognize it, and then uses the force applied by the classification unit 40 to apply the resource. is configured to pass to the moving unit 50 . To this end, the input unit 20 is extended to the inlet 11 of the main body 10 and is inclined to the other end so that the recognition unit 30 can accurately recognize the resource, and transfers the inputted resource to the other end, which is a predetermined position. make it And, the input unit 20 is rotated through the classification unit 40 to be described later to pass the resource to the moving unit 50, so that only the resource falls downward during rotation, in a U-shape or V-shaped upper part open. can be formed. In this case, the open top may be covered with a corresponding fixed cover 21 .

Although the specific shape of the recognition unit 30 is not shown in FIG. 2 , it is formed on the top cover 21 of the other end of the input unit 20 , and recognizes the type of resource seated at the other end of the input unit 20 . The recognition unit 30 may include, for example, a camera including an image sensor, and may acquire information such as an image of a resource in order to recognize the type of resource. As such, the information on the resource obtained by the recognition unit 30 is transmitted to the controller 80 to be described later to determine the type of the resource, which will be described later when described with reference to FIG. 5 . On the other hand, the recognition unit 30 is formed on the other end of the input unit 20, which is inside the body 10, and blocks light coming from the outside in the process of recognizing a resource, so the recognition accuracy is improved. have.

The classification unit 40 is recognized through the recognition unit 30, and rotates the input unit 20 to the left or right according to the type of resource determined through the control unit 80 to be described later. Classify the resources that are settled on the other end. For example, if the identified resource type is plastic, the input unit 20 is rotated to the right, and if the can is the input unit 20 rotated to the left, etc. self-evident In addition, if the identified resource type is a poor resource that cannot be recycled, the input unit 20 is rotated randomly among the left or right side, and the input unit 20 is rotated in any one direction, such as sorting through reverse rotation of the crushing unit 60 to be described later. Classification may be deferred without classification. Alternatively, the input unit 20 may be rotated to one side only for the defective resource, or an approximation to plastic or a can is set in the defective resource, and the defective resource close to the plastic rotates the input unit 20 to the right, Defective resources close to cans may rotate the input unit 20 to the left. The operation of the classification unit 40 is controlled through the control unit 80 to be described later, and the classification unit 40 is specifically configured with a chain including a motor (not shown) to rotate the input unit 20 . can

The moving unit 50 is configured to move the resources classified by the rotation of the input unit 20 through the classifying unit 40 to the crushing unit 60 to be described later. That is, it is formed on the lower left and right sides of the input unit 20 , receives resources classified by the rotation of the input unit 20 , and is inclined to the front or rear of the main body 10 to the front or rear of the main body 10 . The resource is moved to the located grinding unit 60 to be described later. In the present invention, although FIGS. 1 and 2 are illustrated and described based on the fact that the crushing unit is formed at the rear of the main body, the crushing unit may be formed in the front of the main body. As described above, the present invention transfers resources only with the inclined input unit 20 and the moving unit 50, and there is no need for a conveyor belt or a separate motor for driving the conveyor belt, thereby simplifying the apparatus. Rather, it is possible to classify resources with minimal configuration and operation, thereby reducing operating costs and maintenance costs.

The pulverizing unit 60 is configured to pulverize the resources moved through the moving unit 50 , and is formed in the front or rear of the powder unit. In particular, the pulverizing unit 60 pulverizes plastics or cans, which are resources, which are moved to the pulverizing blades 62 formed in the pulverizing zones 60a on the left and right during the forward rotation. Conversely, in the case of reverse rotation, the defective resource, which is a resource, is moved to the non-grinding zone 60b in which the central grinding blade 62 is not formed and classified. In this way, the reverse rotation of the crushing unit 60 makes it possible to easily discharge defective resources such as foreign substances that are not recycled or that are not crushed. no risk for A detailed configuration and function of the crushing unit 60 will be described later with reference to FIGS. 3 and 4 .

The storage unit 70 is formed at the lower end of the crushing unit 60 and is configured to store classified or crushed resources. Specifically, the first and second recyclables storage areas 71a and 71b and the defective resource storage 72 are divided into three zones. The first and second recyclable storage areas 71a and 71b are located at the bottom of the crushing zone 60a formed at both ends on the left and right sides of the crushing unit 60 where recycled resources such as plastics and cans are crushed. Through this, for example, pulverized plastic may be stored in the first recyclables storage 71a, and pulverized cans may be stored in the second recyclables storage 71b. In addition, the storage unit 70 of the present invention includes a storage for defective resources 72, located at the bottom of the non-grinding zone 60b located in the center of the crushing unit 60, and is not plastic or cans, but defective resources or plastics. Defective resources that cannot be crushed by foreign substances inside the can are filtered and stored. As described above, the storage unit 70 of the present invention classifies and stores resources as any one of plastics, cans, and defective resources, so that defective resources that are not recycled can be quickly filtered out. On the other hand, such a storage unit 70 may be configured to be withdrawn through the lower end of the main body 10, and the area of each storage within the storage unit 70 considers the recyclables composition ratio of the area where the device is installed. can be appropriately adjusted.

The control unit 80 will be described later with reference to FIG. 5, but briefly described first, information of the resource recognized by the recognition unit 30, for example, image information of the resource, etc. It can be determined by any one of, for example, can be determined as any one of plastic, cans, or defective resources. Then, the rotation of the input unit 20 or the rotation of the crushing unit 60 through the classification unit 40 is controlled according to the determined type of resource.

Recyclables separation and collection apparatus according to the present invention, including the above-described configuration, is not recycled due to the reverse rotation of the pulverizing unit 60, or defective resources that are not crushed by foreign substances, etc. Defects located at the bottom of the non-pulverizing section 60b Since it can be quickly discharged to the resource storage 72 , there is no need to remove foreign substances from the crushing unit 60 by a separate manpower, thereby reducing the cost for maintenance and reducing the risk.

3 is a perspective view of the crushing unit 60 in the recycling apparatus of the present invention, and FIG. 4 is a side view of the crushing blade 62 in the recycling apparatus of the present invention. The configuration and function of the crushing unit 60 in the apparatus for separating and collecting recyclables according to the present invention will be described in more detail with reference to FIGS. 3 and 4 .

The crushing unit 60 of the present invention includes first and second crushing rods 61a and 61b arranged side by side, and the left and right sides of each of the first and second crushing rods 61a and 61b are crushed into a crushing zone 60a The blade 62 is coupled, and the grinding blade 62 is not coupled to the center, thereby forming a non-grinding zone 60b in which defective resources are discharged as described above. Such first and second grinding rods (61a, 61b) rotate in the inner direction with respect to the upper surface on which the resource is seated during forward rotation, and the resource on the upper surface is moved between the first and second grinding rods (61a, 61b). will be pulled in. On the other hand, when the crushing unit 60 is rotated in reverse, the first and second crushing rods 61a and 61b rotate in an outward direction with respect to the upper surface on which the resource is seated, and the resource on the upper surface is the first, 2 Without being pulled between the grinding rods 61a and 61b, it moves along or discharged along the grinding rods 61a and 61b.

The grinding blade 62 coupled to the grinding rods 61a and 61b may be inclined in the forward rotation direction so as to attract the resource during forward rotation and push the resource during reverse rotation. And, it may be composed of a mixture of a long blade and a short blade so that various resources can be crushed regardless of the shape and size of the resource. More specifically, it may be formed in a side shape as shown in FIG. 4 , and the blade of the crushing blade 62 may be formed only in the forward rotation direction.

And, for the combination of the grinding rods 61a and 61b and the grinding blade 62, a plurality of grinding blades 62 may be formed to cross the first and second grinding rods 61a and 61b. In this case, the grinding blade 62 coupled to the grinding rods 61a and 61b for the movement of the resource may be gradually twisted to form a screw along the first and second grinding rods 61a and 61b. Such a screw may be symmetrically formed on the first and second grinding rods 61a and 61b to move the resource in one direction. And the screw may be formed not only symmetrically to the first and second grinding rods 61a and 61b, but also symmetrically to the left and right of each grinding rod 61a, 61b. Through such a screw, the grinding unit 60 may pull the left and right ends of the resource in the forward rotation, and push the resource to the non-grinding zone 60b in the center in the reverse rotation.

As described above, through the grinding blade 62 inclined in the forward rotation direction and composed of a detailed blade of a mixture of long and short blades, the device of the present invention can attract resources better, and resources of various shapes and sizes can be crushed. In addition, a non-grinding zone 60b is formed in the crushing unit 60, and defective resources such as bad resources can be discharged to the non-grinding zone 60b with a screw through the crushing blade 62, and defective resources such as foreign substances can be removed by itself. can be removed, reducing maintenance costs and reducing risk.

5 is a schematic view for explaining a process in which the control unit 80 controls the classifying unit 40 and the crushing unit 60 in the recycling apparatus of the present invention. With reference to FIG. 5, in the apparatus for separating and collecting recyclables according to the present invention, the operating principle of the present invention through the control unit 80 will be described in detail.

As shown in FIG. 5 , the controller 80 first determines the type of resource through information about the resource received from the recognition unit 30 , for example, image information. Such determination of the type of resource may be an artificial neural network analysis based on image recognition, and may specifically refer to Korean Patent Registration Publication No. 10-1779782. Referring to No. 10-1779782, the controller 80 may be configured to determine the type of resource based on the artificial neural network analysis of the image information recognized by the recognition unit 30 .

Then, the controller 80 controls the rotation of the classifying unit 40 and the crushing unit 60 as shown in FIG. 5 according to the determined resource type. When the determined type of resource is a recyclable plastic or can, the control unit 80 rotates the classification unit 40 to the left or right to classify the resource, and rotates the crusher 60 in the forward direction to crush the resource. On the other hand, if the determined type of resource is a poor resource that cannot be recycled, the control unit 80 rotates the classification unit 40 to either side to move the resource, and rotates the crusher 60 in the reverse direction to reduce the resource. It is classified and moved to the bad resource storage 72 .

Meanwhile, although not shown, a motor is coupled to the crushing unit 60 , and the control unit 80 may determine whether the crushing unit 60 is normally operated through a change in current driven by the motor. Alternatively, a force sensor may be coupled to the crushing unit, and the control unit 80 may determine whether the crushing unit 60 operates normally through the force sensor. As a result, when the pulverizing unit 60 does not operate normally and thus the resource cannot be pulverized, the pulverizing unit 60 may be reversely rotated to push the resource to the non-pulverized zone 60b.

From the above description, those skilled in the art to which the present invention pertains will understand that the present invention may be implemented in other specific forms without changing the technical spirit or essential characteristics thereof. In this regard, it should be understood that the embodiments described above are illustrative in all respects and not restrictive.
