Description

TECHNICAL FIELD The present invention relates to a packaging container separating apparatus for separating plastic packaging containers, particularly plastic packaging containers used as food packaging containers, for each material.

As modern people's consumer activities become more and more active, many critical situations of the global environment have been reported. One major aspect of environmental problems is global warming. The importance of the efforts of each individual consumer is screaming as international agreements on reducing carbon dioxide emissions are concluded. Laws to comprehensively promote the 3R (Reduce, Reuse, Recycle) efforts necessary to form a recycling-oriented society have been enforced, and social movements to curb power consumption such as Cool Biz and Warm Biz are widely conducted. It has been broken.

One typical approach to addressing individual consumers' environmental issues is the collection of waste. Paper resources such as newspapers, magazines, and milk cartons and containers such as empty bottles and empty cans are being used by local governments and local communities, which actually contributes to improving the collection rate.

As a technology that enables efficient separate collection and reuse after these paper resources, empty bottles, empty cans, and the like are collected, technologies relating to various container sorting apparatuses are disclosed. For example, Patent Document 1 discloses a technique related to a glass container sorting device, and according to this, it is possible to efficiently perform a sorting operation for each color of a glass bottle. Patent Document 2 discloses a technique related to a collection device that separates and collects empty cans and PET bottles according to materials. Patent Document 3 discloses a transfer means for continuously separating, cleaning, and dewatering paper containers.

Japanese Patent No. 30358803 JP 2000-172909 A JP 2004-323138 A

By the way, a wide variety of materials are used for various packaging containers such as meat, seafood, side dishes, lunch boxes and the like, mainly food containers. Most of them are plastic packaging containers, and it is indispensable to improve the reuse rate to collect such plastic containers for each material. From this point of view, the plastic packaging container is actually provided with marks indicating the respective materials.
However, even with such a mark, there is a fact that appropriate separate collection is not performed. In some municipalities, garbage collection and waste collection are also carried out even in garbage collection, but the fact is that packaging containers of different materials are mixed and discarded, which is not effective. This can be said to be a plastic packaging container in one bite, or it can take only the thermoplastic resin often used in food containers, PE (polyethylene), PP (polypropylene), PS (polystyrene), PVS (polyvinyl chloride) One of the reasons is that it is difficult to discriminate these in a general household, such as PET (polyethylene terephthalate).
In addition, resource recovery forms such as waste collection and periodic garbage collection have a negative impact on the improvement of the recovery rate and reuse rate. This is because the frequency of collection of individual garbage is reduced due to diversification of collection types, and the period in which the garbage must be stored at home is lengthened. Therefore, resources remain mixed (for example, “ This is because there are many cases of disposal (on the day of burning garbage).

Therefore, if an efficient collection device for each material can be installed at regular places such as supermarkets, shopping streets, and station premises, general consumers will put their household garbage in the collection cycle every time they go out, for example. Can be convenient. Therefore, the problem of the present invention is that plastic containers can be separately collected for each material, and can be compactly installed, for example, in a supermarket, a shopping street, a station premises, etc. Another object is to provide a plastic packaging container separation and recovery device that can be used together. Furthermore, when it is installed in a public place as described above, there is a possibility that foreign matter that should not be thrown in will be thrown in. It is to provide a recovery device.

In order to solve the above problems, the present invention has the following configuration.

That is, the container separation and recovery device according to the present invention is a container separation and recovery device for separating and collecting used plastic packaging containers, and includes an input port for loading used packaging containers, and the input port.

With such a configuration, the material discriminating means distinguishes and recognizes the container for each material, performs sorting of the input based on this recognition, and collects it in each container container provided for each type of material. it can. In addition, a determination area is provided, a flow path is provided that directly connects the determination area and the container container according to the determination result, and the input is distributed by a mechanism on or along the flow path. Therefore, it is possible to reduce the size of the entire apparatus, and no space is wasted when it is installed in a place such as a supermarket or a shopping street where there is a lot of traffic.

The foreign matter determination means includes a camera for photographing the determination area, shape recognition means for recognizing the shape of the input in the determination area from image information output from the camera, and the shape of the container to be collected. A shape threshold storage means for storing the threshold, and when the shape recognized by the shape recognition means is within the range of the previous shape threshold, the container may be determined to be a collection target container. (Claim 2).

With this configuration, it is possible to determine whether the input is a packaging container to be collected or other foreign matter based on the shape of the input, and quickly remove obstacles during container recovery. Is possible.

Further, the material discriminating means may be configured to discriminate the material by near infrared spectrum analysis. With this configuration, the material can be instantly identified without contacting the container or destroying the container, and the efficiency of the apparatus is improved.

Further, a color tone discrimination means may be further provided so that the color tone is taken into consideration in addition to the material when recognizing the properties of the input material. This improves the accuracy of container separation and contributes to further improvement in recycling efficiency.

Further, as a specific aspect of the input material distribution means, it is provided in a flow path arranged between the determination region and the plurality of container containers, and according to the determination result by the material determination means, A structure having a guide member that switches a flow channel, and an input material delivery mechanism that discharges the input material from the discrimination region and sends it to the flow channel using gravity after the flow channel is switched by the guide member. (Claim 5).

According to such a configuration, the properties of the packaging container to be collected are determined, and after the flow path is switched according to the properties, the packaging container is sent out to the flow path. It is securely stored in the corresponding container container.

Alternatively, it has a transfer means for transporting the input charged from the input port, the foreign matter determination means and the material determination means are arranged along the transfer means, the input distribution means, It is a member with an arm installed beside the transfer means, and is driven based on the determination result of the material determination means, and guides the input material conveyed by the transfer means to a corresponding container container.

Means may be provided (claim 9).

(Definition of terms)
Here, examples of the “plastic packaging container” and “collection target container” include PP (polypropylene), PE (polyethylene), PS (polystyrene), PVC (vinyl chloride), and PET (polyethylene terephthalate). Although the food container is mainly assumed of the thermoplastic resin material, it is not limited thereto, and may be a container of a thermosetting resin material such as PUR (polyurethane) or EP (epoxy resin). In addition, the purpose of the container itself is not limited as long as it is made of a material that can be discriminated, and it is a uniform shape and size that can be collected. It may be a container.

Further, the “input port” means an opening for putting a container to be collected into the apparatus, and does not need to be always opened, and for example, an openable / closable lid may be provided. In this case, it is possible to prevent the odor of the food remaining on the container from leaking out of the apparatus. “Detained for a predetermined period” means that the input is kept in the state necessary for foreign matter determination and material determination. It is not always necessary to keep the input stationary, but the input distribution means is appropriate based on the result of property determination. It is necessary to provide a time delay until a proper operation is performed, and it is necessary to provide a time buffer at the minimum and to perform property determination during that time.

“Characteristics of the input” means whether the input is a foreign substance and what the material is. Furthermore, the color tone of the outer surface of the input material (for example, it may be a specific individual color tone or a rough categorization, for example, classification according to the color tone such as “transparent”, “white”, “colored”, “pattern”). Can also be recognized as a property. “Near-infrared spectrum analysis” means that the material is irradiated with light in the near-infrared region, mainly in the wavelength range of 0.8 to 25 μm, and the absorption characteristics of the material's infrared light based on the spectrum obtained from the diffused light. It is a material property measurement technique that is obtained and used to infer components and materials. For example, a plastic identification device “sIRoLine” manufactured by German company IoSys can be applied.

The “flow path” means a moving path of the input material, for example, a space for allowing the input material to fall freely, or a slope for moving the input material using gravity. May be.
The “transfer means” may be any means for moving the input material from the input port to the discrimination area, and further to the part where the input material distribution means is located. For example, a belt conveyor is applicable.

With the container sorting and collecting apparatus according to the present invention, the general consumer himself can even insert the target plastic packaging container from the inlet without being particularly conscious of the packaging container material he / she intends to input. Therefore, it does not cause an excessive burden on general consumers and is expected to improve plastic resource recycling efficiency, which has not been realized in the prior art, and contributes to prevention of global warming and environmental protection. In addition, the general consumers themselves can feel the involvement in environmental problems by being involved in resource recovery, and a secondary effect of increasing awareness of environmental problems can be expected.

In addition, the provision of the foreign matter determination means and the provision of means for discharging or notifying the foreign matter based on the result of the determination result in the assumed mischief in the sorting and collecting apparatus according to the present invention assumed for a large number of users. There is a possibility that the operation stoppage of the apparatus can be prevented to a certain extent.

The best mode for carrying out the present invention will be described below with reference to the drawings.

FIG. 1 is a conceptual block configuration diagram of a container sorting and collecting apparatus 1 according to a first embodiment of the present invention. There are plastic packaging containers C made of various raw materials (raw materials), and there are various shapes. A general consumer throws in a used packaging container C through the slot 101. The insertion port 101 can be provided with a manual or automatic lid in order to prevent the odor inside from leaking out. Further, by setting the size or shape of the insertion port 101 to a specific size or shape, it is possible to prevent an article that should not be originally introduced from being erroneously introduced to some extent without depending on foreign matter determination described later. be able to. For example, among food packaging containers, when specializing in containers used for meat or fresh fish, etc., when trying to promote recovery, these shapes have a relative height ratio relative to the length and width. Since most of them have a low shape, an adapter (not shown) limited to the shape of the insertion port 101 may be provided.

In the indwelling area 102, an input recognition camera 103 for imaging the inside of the area and a plastic discrimination sensor 104 for discriminating the material of the packaging container C placed in the indwelling area are respectively provided with stages (opening / closing ports). ) It is arranged so that 105 is captured. Here, a CCD (Charge Coupled Device) camera is used as the input recognition camera 103. For more precise shape recognition, it is desirable to use imaging from a plurality of points. However, in this embodiment, it is possible to determine whether or not the input is a packaging container C to be separated and collected. There is no need to perform imaging processing from multiple viewpoints. The packaging container C that reaches the indwelling area 102 through the insertion port 101 is discriminated in its properties in the indwelling area 102.

The stage (opening / closing opening) 105 is a place where the input packaging container C is to be placed. The stage (opening / closing port) 105 is configured to be opened and closed by an actuator (not shown) that operates based on signals from the material determination processing unit 106 and the imaging determination processing unit 110. Thereby, the placed input is sent out to the flow path 107 at an appropriate timing. The stage (opening / closing port) 105 corresponds to an input material feeding mechanism, and the detention area 102 and the stage (opening / closing port) 105 retain the input material for a predetermined period, and determine the property of the input material by the foreign matter determining means and the material determining means. This corresponds to the determination area.

Each of the material determination processing unit 106 and the imaging determination processing unit 110 is a microcomputer including an arithmetic device, a storage unit, and an input / output port. The material discrimination processing means 106 is connected to the plastic discrimination sensor 104, processes information on the material output from the plastic discrimination sensor 104, and identifies the material. The imaging determination processing unit 110 is connected to the input recognition camera 103, determines whether the input is a collection target or a foreign object based on image output information from the camera, and changes the color tone of the packaging container C. Recognize and remember. In addition, although both are described as different in the configuration diagram, it does not preclude physically having the same configuration.

FIG. 2 is a flowchart showing a flow from when an input is input until it is separately collected. In the present embodiment, the separate collection of the packaging container C is started when the packaging container C is inserted by the general consumer and the collection switch S (not shown) is pressed as described above (step S201). ). First, the shape of the input is determined (step S202).

FIG. 3 is a subroutine showing the flow of shape determination. First, the input recognition camera 103 performs imaging recognition of the input placed on the stage 105 (step S301). At this stage, the presence or absence of an input is recognized (step S302). This is because it is conceivable that the general consumer depresses the input switch S without inputting the input material, or the image is not placed on the stage 105 so as to be imaged as a result of inappropriate input of the input material. If the input cannot be recognized (step S302: NO), the fact is notified to the general consumer (step S303).

When the input is recognized (step S302: YES), the shape of the input is measured (step S304). Specifically, the captured screen is divided into predetermined vertical and horizontal widths, the maximum values of the vertical and horizontal lengths of the input image are recognized, the aspect ratio is obtained, and temporarily stored in the imaging determination processing unit 110. Store in the area. Next, the above-described aspect ratio is compared with the shape threshold value stored in advance in the imaging determination processing unit 110 (step S305). Here, the shape threshold value defines an upper limit and a lower limit of the aspect ratio that can be captured when an image of the shape threshold is taken in consideration of the shape features that are generally provided in packaging containers. Here, it is assumed that the shape threshold value X is predetermined as 0.3 <X <1.8.

For example, in FIG. 4A, the ratio (M / N) of the vertically long M and the horizontally long N on the imaged screen is approximately 0.52, which is within a predetermined threshold range. On the other hand, in FIG. 4B, the ratio (M ′ / N ′) between the vertically long M ′ and the horizontally long N ′ in the captured image is approximately 0.18, which is outside the predetermined threshold range. If the ratio is within the threshold (step S305: YES), it is determined that the input is a collection target, and the process returns to the main flow. When the ratio is outside the threshold (step S305: NO), it is considered that the packaging container is outside the range of the shape that the packaging container normally has, and a signal indicating that the input is discharged from the imaging determination processing unit 110 is a stage (open / close port). ) 105 and the foreign matter discharge port 111, and the input is discharged from the foreign matter discharge port 111 through the flow path 107 by gravity (step S306). Thus, the input recognition camera 103 and the imaging determination processing unit 110 correspond to a foreign matter determination unit.

Returning to FIG. 2, next, the color tone discrimination of the packaging container C is performed (step S203). Data recognized by the input recognition camera 103 is output to the imaging determination processing unit 110 as image output information. The storage area in the imaging determination processing unit 110 stores a color recognition look-up table (not shown) in advance, and identifies which color tone it is by comparing with image output information. In this embodiment, four types of identification are performed: “transparent”, “white”, “colored”, and “pattern”. When the color tone is identified, the imaging determination processing unit 110 outputs an imaging identification signal to the guiding member control unit 112.

The guide member control unit 112 drives the guide member 108 to change its arrangement based on an imaging identification signal output from the imaging determination processing unit 110 and a material identification signal described later. Thus, in the present embodiment, the input recognition camera 103 and the imaging determination processing unit 110 also function as a color tone determination unit. Of course, you may provide the separate camera and processing mechanism (microcomputer) according to each determination means.

Next, the material discrimination of the packaging container C is performed (step S204). Specifically, this step is performed along the flow of a subroutine shown in FIG.

First, irradiation with near infrared light is performed (step S501), and diffused light reflected by the packaging container C is received (step S502). Based on the data thus obtained, the material is identified (step S503). Specifically, the horizontal axis is the wave number (a numerical value representing the frequency per unit length (1 cm) according to the calculation formula of 10,000 / wavelength (μm)), and the light transmittance (%) of each region is expressed as follows. A continuous curve (spectrum chart) having a vertical axis is obtained, and this is compared with the spectrum chart for each material stored in the material discrimination processing means 106 in advance, so that the most approximate chart shape is the material of the packaging container C. To identify.

When the material is identified as described above, the material discrimination processing unit 106 outputs a material identification signal to the guide member control unit 112 (step S504). The guide member control means 112 that has received the material identification signal drives to change the arrangement of the guide member 108 in order to guide the packaging container C that has fallen into the container container 109 of the material indicated by the received signal. Thus, the plastic discrimination sensor 104 and the material discrimination processing means 106 correspond to the material discrimination means.

Returning to FIG. 2 again, the input is sent out (step S205). In this embodiment, a signal indicating that the material has been identified is output from the material discrimination processing means to the stage (opening / closing port) 105. In response to this, the stage (opening / closing opening) 105 is driven to open. The packaging container C placed on the stage (opening / closing opening) 105 falls according to gravity, is guided by the guide member 108 through the flow path 107, and is provided for each property container container 109 ... 109. Of these, it is separated and collected into an appropriate container container 109 (step S206). Thus, the guide member control means 112 and the guide member 108 correspond to the input sorting means.

In this embodiment, it is assumed that the device is driven when the general consumer presses the collection switch S. However, the present invention is of course not limited to this, and for example, the input recognition camera 103 is always started and thus the input is performed. It can also be set as the structure which a collection | recovery apparatus drives by the presence of an object being recognized. Further, in the present embodiment, the flow path 107 is configured so that the packaging container C naturally falls, but instead, it may be configured to have an inclined slope and slide down the inclined surface.

Next, a second embodiment according to the present invention will be described with reference to the drawings. In addition, about the structure which is common in a 1st Example, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

FIG. 6 is a conceptual diagram of a container sorting and collecting apparatus according to the second embodiment. The upper part is a view of the device viewed from the side, and the lower part is a view of the device viewed from above. The input material input from the input port 101 is gradually conveyed by the conveyor 605. In this embodiment, the input recognition camera 103 and the plastic discrimination sensor 104 project from the upper surface side of the conveyor so that the input placed on the conveyor can be best imaged and recognized along the conveyor. Is arranged to be possible. As in the first embodiment, the input recognition camera 103 and the plastic discrimination sensor 104 perform imaging and analysis in order to determine the properties of the input flowing by the conveyor. In this embodiment, the illustrated discrimination area 602 corresponds to the discrimination area.

Here, when it is determined as a foreign object, the input material is repelled from the conveyor in the foreign object return mechanism 611. Specifically, a pop-up mechanism is provided on the roller in the conveyor of the part, and the foreign matter return mechanism 611 that has received an output signal indicating that it is a foreign matter from the imaging determination processing unit 110 drives the pop-up mechanism to convey the conveyor. It can be excluded from above.

In this embodiment, an armed member 608A and an air ejection device 608B are used as the input material distributing means for guiding the packaging container C to the container container 109 according to its properties. This is a configuration that can be taken from the fact that the input containers are sequentially conveyed by the conveyor, while the packaging containers C to be distributed are generally lightweight.

With respect to the member 608A with an arm, the packaging container C receives a color tone identification signal from the imaging determination processing unit 110 and a material identification signal from the material determination processing unit 106, and when the packaging container C passes a predetermined position, for example, the determination area 602. To drive. Here, a member 608A with an arm provided at the entrance of the container container 109 of the corresponding material extends obliquely in a direction reverse to the conveying direction of the conveyor toward the conveyor, and along the arm as the conveyor rotates. Thus, the packaging container C is accommodated in a predetermined container container 109. Here, the member with arm 608A corresponds to the input sorting means.

The air ejection device 608B receives the color tone identification signal from the imaging determination processing means 110 and the material identification signal from the material discrimination processing means 106, and the packaging container C is in a predetermined position, that is, a container containing the corresponding material. At the timing when the sheet is transported to the front of the body 109, the air ejection device 608B installed at a position facing the conveyor 109 is driven to eject the air AB, and the packaging container C is guided to the predetermined container container 109. To do. Here, the air ejection device 608B corresponds to the input distribution means.

In the second embodiment, as a specific configuration of the input distribution means, an apparatus in which the armed member 608A and the air ejection device 608B coexist has been described as an example. There is no such relevance, and only the input sorting means that can be applied in the conveyor transport type container sorting and collecting apparatus is illustrated. Therefore, for example, the specific structure of the input distribution means to be mounted may be only the armed member 608A or only the air ejection device 608B.

Further, in each of the above-described embodiments, the color tone discrimination in the imaging determination processing unit 110 is one element of the property discrimination. However, the present invention is not limited to this.

Moreover, each structure raised as an example illustrates this invention, and is not the meaning limited to the said structure only.

1 is a conceptual block diagram of a container sorting and collecting apparatus according to a first embodiment of the present invention. In the container fraction collection apparatus according to the first embodiment of the present invention, it is a main flow from when an input material is thrown into until fraction collection. This is a foreign matter determination subroutine. It is a conceptual diagram in which the shape of an input material is determined, and is an imaging image diagram when a container to be collected is input. Similarly, it is an imaging image figure when a foreign material is thrown in. This is a material discrimination subroutine. It is a conceptual diagram of the container classification collection apparatus which concerns on the 2nd Example of this invention.
