Description

DESCRIPTION

Packaging typology detection system

Object of the invention

The present invention pertains to the technical field of waste collection systems. In particular, the invention describes systems for providing collection capacity and selective detection of containers in recycling containers located on urban streets.

Background of the invention

Recycling, or separate waste collection, allows for the recovery and reintegration of used materials into the production cycles of new products, resulting in a significant and valuable reduction in the raw materials and energy required to produce these new products. This, in turn, brings with it a series of benefits, including a reduction in pollution generated, the elimination or improved sustainability of existing landfills, and an overall improvement in environmental health and well-being.

For years, there has been growing international concern about the management of waste generated by a society with increasingly accelerated consumption habits. In this regard, over the last century, a series of international conferences and treaties have been held to raise global awareness about the role that resource management plays in issues as critical to sustainability as climate change, as well as to seek to harmonize the actions of different jurisdictions, both national and regional. In this regard, the United Nations itself, through the United Nations Environment Programme (UNEP), has developed a guide for the Development of National Waste Management Strategies. All of this has led to the development and implementation of various recycling plans at the regional or local level.

The various local selective collection strategies and plans essentially consist of separating solid urban waste prior to its disposal at collection points, usually located on public roads and generally in the form of various types of containers, classified according to the waste category. These containers store a specific volume of waste so that it can be collected by local teams and subsequently recycled.

Among all the waste products generated by the population, lightweight packaging occupies a special place. Specifically, this category includes packaging made of different types of materials, including: plastic containers (water bottles, milk bottles, hygiene product bottles, yogurt bottles, etc.), cartons (for beverages such as juice, wine, milk, etc.), plastic bags, aluminum cans (for soft drinks, canned goods, etc.), polystyrene trays, and aluminum foil.

Due to this diverse nature, prior to the specific recycling process for each product based on its composition, lightweight packaging must be sorted and selected in the waste reception areas of treatment plants. Specifically, the collected waste is transported to the separation facilities, where the waste mass is sorted through a combination of mechanical or automated separation processes and manual processes to separate and recover the different recoverable fractions and prepare them for subsequent recycling in the corresponding facilities according to the type of material. During these screening and selection processes for recyclable material, a certain volume of rejects is generated, which results in a reduction in the efficiency of the overall selective collection and subsequent treatment process. These rejects will be destined for final disposal in a landfill or incineration for energy recovery.

In view of all the above, it is clear that the first link in the chain, that is, citizen collaboration and involvement, carrying out the initial stage of waste sorting and selection, and particularly lightweight packaging, is essential to ensuring the efficiency of the entire network of stages and intermediaries involved in the recycling chain downstream. Therefore, a crucial section for ensuring the effectiveness of plans for the selective collection and treatment of urban solid waste is the section dedicated to raising awareness and motivating the public through various environmental education strategies and campaigns to achieve their active participation in these plans.

In this context, one of the distinguishing features of the various waste treatment plans developed locally by cities or even municipalities is the characteristics (size, morphology, operating mechanisms, etc.) of the containers. This can lead to significant differences in the optimization and effectiveness of these plans between different localities within the same territory, due to the difficulties or obstacles that the configuration of the containers may pose to citizens in their proper use. Therefore, the role played by containers installed in public spaces is of great importance.

Document CN112110089A describes an intelligent device for collecting packaging material from commodities.

Description of the invention

The present invention provides a container typology detection system attachable to a container according to claim 1, and a container according to claim 15. Preferred embodiments of the invention are defined in the dependent claims.

The container typology detection system attachable to a container of the invention comprises:

- a mechanical module comprising:

a docking interface configured to be releasably attached to an opening of the container, the docking interface further comprising an opening configured to allow access of containers to the interior of the container type detection system; and

a main body integrally connected via a proximal end to the coupling interface, projecting toward the interior of the container, defining a receiving chamber configured to temporarily house containers that enter the interior of the system through the opening in the coupling interface; the main body further comprising an opening at a distal end facing toward the interior of the container to allow containers leaving the system to be released into the interior of the container;

- a detection module comprising at least one of the following sensor means:

first sensor means configured to detect at least one product identification code arranged on a package;

second sensor means configured to detect a metallic composition of a container; third sensor means configured to detect a polymeric composition of a container; and - an electronic module comprising data processing means;

wherein the first, second and/or third sensor means are configured to generate a data signal with detected information relating to the type of container when it is temporarily housed in the receiving chamber; and to transmit said data signal to the data processing means; and

wherein the data processing means are configured to determine at least one type of packaging based on: at least one product identification code and/or metallic composition of the packaging and/or polymeric composition of the packaging; and

- a power module configured to provide power to the elements comprised in the detection module and in the electronics module.

The system of the invention is a system that can be inserted into containers through an opening and coupled to said opening for attachment to the containers. Said containers are preferably containers for selective collection of lightweight packaging that can be placed, for example, on urban roads. Thus, the system of the invention provides the containers with the ability to identify the nature and type of packaging introduced inside, based on measurements and/or captures taken by a series of detection and sensing elements that extract information from the lightweight packaging once introduced. Based on said analysis, the system can determine, for example, whether the deposited container is a PET soft drink bottle, an aluminum soft drink can, a steel soft drink can, or another type of container.

In this way, the system coupled to the container provides early, on-site sorting of waste deposited in suitable containers, facilitating subsequent sorting at separation and treatment plants. Furthermore, in advantageous embodiments, the invention allows tracking of those containers deposited in specific containers by specific users and prevents tampering or fraud in the counting and traceability of said deposits.

At the user level, a container-assisted disposal process is provided, making recycling easier and less vulnerable, and ensuring a clear understanding of the relationship between the container the user intends to dispose of and the type of container selected.

In this way, the system of the invention helps to increase the overall efficiency of selective waste collection plans by contributing to greater efficiency in the phase corresponding to the initial sorting or screening of lightweight packaging, minimizing the multiplying impact, in successive stages of the recycling chain, of the introduction of incorrect packaging.

In addition, public awareness can be strengthened with discount schemes by counting the number of containers deposited by a specific user. This system is implemented with traceability technology and prevents fraudulent schemes seeking multiple discounts for the same container deposited.

In one embodiment, the detection module comprises:

the first sensor means configured to detect the at least one product identification code arranged on the packaging;

the second sensor means configured to detect the metallic composition of the container; and the third sensor means configured to detect the polymeric composition of the container.

In other embodiments, the detection module comprises one of the first sensor means, the second sensor means or third sensor means or two of the first sensor means, the second sensor means and the third sensor means in any of the possible combinations.

In one embodiment, the detection module further comprises image capture means configured to generate a data signal with information detected by the image capture means, and to transmit said data signal to the data processing means.

In a preferred embodiment, the image capture means comprise a wide-angle camera.

Advantageously, the use of a wide-angle camera optimizes image capture capacity. In particular, the use of this technology allows for a reduction in the volume of the receiving chamber and, therefore, of the main body of the mechanical module, since these cameras have a larger field of view (FOV) than conventional cameras. This allows the camera to be positioned closer to the location the containers will occupy inside the receiving chamber, i.e., inside the system.

In one embodiment, the image capture means comprise artificial lighting means.

The ability to capture images in a closed, dark environment is significantly improved by implementing artificial lighting technology, such as flash lighting. More specifically, in an embodiment in which the system wirelessly transmits the images captured by the wide-angle camera to a remote server, allowing the remote server to process the images using deep learning methods, the artificial lighting optimizes the recognition of the shapes and appearance of the photographed container.

In one embodiment, the detection module additionally comprises at least two motion detection sensors configured to detect the passage of a container through two different locations in the receiving chamber, one location closest to the proximal end of the main body and the other location closest to the distal end of the main body. According to this embodiment, the data processing means are configured to receive a signal from the at least two sensors and determine, based on said signal, the direction of movement of the container.

Advantageously, the presence of said sensors will allow the detection of an attempt at fraudulent deposit within the system. In particular, fraudulent deposit of a container will be understood to involve the movement of said container from a distal position, i.e., close to the interior of the container, to a proximal position, i.e., close to the opening through which the container entered. That is, said movement will be assumed to be contrary to the natural direction of introduction of a lightweight container into a container: from the outside, through an opening in a proximal area, to the interior of the container, through a distal area of the main body of the invention after traveling a certain length along the receiving chamber. Therefore, said movement in the opposite direction will be associated with an irregular extraction operation of the lightweight container.

In particular, the motion detection sensors are arranged so that their detection fields cover different locations on the internal surface of the main body, i.e., different sections of the receiving chamber. Each of the motion detection sensors will communicate, by generating and sending corresponding signals, with the data processing means responsible for processing said signals to finally determine, based on the information provided by the sensors, the direction of movement of the container. In a particular embodiment, the at least two motion detection sensors are optical sensors oriented towards the interior of the receiving chamber.

In a particular embodiment, each of said motion detection sensors is located in a different section of the receiving chamber and/or is oriented to detect the passage of a container through at least one plane substantially transverse to the main body, said planes being located in different sections of the receiving chamber.

In a particular embodiment, the data processing means process the information received from the motion detection sensors to determine any of the following scenarios:

i) If a motion detection sensor detects the passage of an object through a location closer to the proximal end of the main body, sending the corresponding signal to the data processing means, and subsequently a motion detection sensor detects the passage of an object through a location closer to the distal end of the main body, sending the corresponding signal to the data processing means, the data processing means will determine that the container is moving through the interior of the system in the correct direction, therefore being a legitimate deposit.

ii) If a motion detection sensor detects the passage of an object through a location closer to the distal end of the main body, sending the corresponding signal to the data processing means, and subsequently a motion detection sensor detects the passage of an object through a location closer to the proximal end of the main body, sending the corresponding signal to the data processing means, the data processing means will determine that the container is advancing through the interior of the system in the opposite direction to the correct direction, thus identifying a fraudulent deposit.

In one embodiment, the system further comprises a user interaction module, which in turn comprises a user interaction interface facing away from the container opening; and user authentication means configured to recognize a user.

In one embodiment, the user authentication means are configured to wirelessly interrogate a user identifier that may be a portable device with NFC and/or Bluetooth® technology, such as a card or a smart mobile phone.

In one embodiment, said identifier is general or common and is not associated with specific users; it simply meets a specific criterion to be identifiable or recognizable by the user authentication means. In another embodiment, said identifier is associated with a specific user previously registered on a web platform accessible by the user, e.g., through a web application. Thus, once said users are registered on the web application, they are registered in a database of registered users along with their identifiers so that interrogation of said identifiers by the authentication means allows the association of a deposit action with a specific user.

In one embodiment, the user authentication means are configured to detect the user ID via an interrupt pin of the data processing means, which reacts and alerts upon detection of proximity of a user ID. In particular, said interruption is achieved by preparing the operating code of the authentication process to be pending an external signal. Upon detection of a user ID, via, for example, communication with a portable device using NFC and/or Bluetooth® technology, or a countdown, said external signal is generated, triggering the execution of the code, which interrupts the current work cycle without waiting for its completion.

In one embodiment, the user interaction module additionally comprises information presentation means configured to provide information relating to the determination of the type of container introduced into the system by means of data processing means.

Advantageously, the information display will serve as a guide so that the user undergoing the packaging disposal process understands the sequence of steps and, at the end, ensures that the packaging they wish to dispose of matches the container they selected.

Specifically, if the container entered into the system meets the established criteria for that deposit, for example, a PET plastic bottle or an aluminum soda can, the user will be informed of the success of the operation. Otherwise, if the deposit is not completed as expected (e.g., due to the wrong type of container, etc.), the user will also be duly informed.

In one embodiment, the information display means comprise at least one of: LED type light indicators, and/or acoustic signal emitters and/or a screen.

In one embodiment, the electronic module comprises wireless communication means configured to transmit to a remote server information relating to determining the type of container introduced into the system, wherein said information is at least one of:

- product identification code;

- metallic composition of the container;

- polymeric composition of the packaging;

- captured image of the packaging

- identified user registration;

- temporary mark of deposit of the container.

In a more particular embodiment, the wireless communication means comprise a modem of the GSM, or GPRS, or LORA type, etc.

The remote server can correlate the information received with packaging typology data to determine whether the packaging entered into the system is, in fact, a lightweight packaging that meets the requirements for placement in the container in question.

Advantageously, in addition to confirming and recording that a specific user has successfully deposited a container into a container, the remote server can process all the information through the system of the invention to update the profile of the registered user who performed the action. This way, it will be possible, for example, to reward said user through an online computer application or one installed on their own mobile device, based on a reward system defined to encourage citizen participation in selective waste collection plans.

Using these wireless communication devices configured to communicate with a remote server, the authentication devices can send the result of the query to the remote server, which houses the database of registered users. The information is then remotely processed to determine the user's authentication, that is, to verify whether they are registered in the web application.

In one embodiment, the electronics module further comprises data storage means comprising a database of packaging types classified based on at least one of: product identification codes, metallic composition of the packaging, and polymeric composition of the packaging; and wherein the data processing means are configured to determine at least one packaging type by comparing the information received from the sensor means in the form of a signal with the database of packaging types stored in the data storage means.

In one embodiment, a list of registered users is stored locally in these data storage media, such that the result of the query is processed locally to determine whether the user is registered in the web application.

In a preferred embodiment, the composition detection carried out by the second and third sensor means is performed in situ, i.e., locally. In particular, the second sensor means are calibrated around a value that provides adequate sensitivity to detect the metallic composition of the container, and the third sensor means collect chemical information about the container, which is compared to a library of spectral signatures stored in the data storage means to select the pattern corresponding to said collected information. The detection of the product identification code by the first sensor means and the image recognition are performed remotely on a server to which the related information is transmitted wirelessly.

In one embodiment, the data storage means stores information relating to at least one determination of the type of container introduced into the system, wherein said information is at least one of:

- product identification code;

- metallic composition of the container;

- polymeric composition of the packaging;

- captured image of the packaging

- identified user registration;

- time stamp of receipt of the package.

After completing the detection and analysis of a container, the system will be able to locally record all relevant information about its characteristics, as well as assign a time stamp and a profile to a specific user, thus providing valuable feedback on system usage that can be used to extract statistical information regarding the level of participation and efficiency of recycling programs.

Storing information locally is advantageous in the case where, in an implementation involving wireless communication media, there are, for reasons beyond the control of the system itself, problems with connectivity to the wireless network.

According to the invention, the mechanical module comprises:

a first lockable gate configured to prevent or allow the passage of containers through the opening of the coupling interface of the mechanical module; and

first actuating means controlled by the data processing means for locking or unlocking the first gate;

wherein the data processing means are further configured to control the first actuating means according to the following instruction:

If a container is inside the receiving chamber being analyzed by the detection module, block the first gate to prevent the passage of containers into the system.

In one embodiment, the data processing means are further configured to control the first actuating means according to one of the following instructions:

- if no container is detected inside the receiving chamber, unlock the first hatch to allow a container to pass into the system; and/or

- If a user registration is detected using the user identification means, unlock the first gate to allow containers to pass into the system.

In a particular embodiment, the first lockable gate is shaped like a flat disc and is configured to move in a plane perpendicular to the input direction, describing a circular path pivoting around a point, to slide from a rest position in which it prevents the passage of containers through the opening of the coupling interface of the mechanical module to a displaced position in which it allows it.

In one embodiment, the mechanical module comprises:

a second hinged gate configured to retain and release a container upon exiting the system through the opening at the distal end of the main body; and

second actuating means controlled by the data processing means for controlling the lowering of the second gate;

wherein the data processing means are further configured to control the second actuating means according to any of the following instructions:

- If a container is inside the receiving chamber and is being analyzed by the detection module, retain it with the second gate, preventing it from being collapsed; and/or

- If a container is inside the receiving chamber and the determination of the type of container introduced has been completed, fold down the second door to allow the container to be released from inside the system into the container.

In a particular embodiment, the second folding gate, i.e., the exit gate of the system into the container, comprises a frame assembly with a spring-loaded trapdoor, wherein the assembly moves relative to a horizontal axis as a hinge for its folding. The second actuating means act on the assembly, allowing the trapdoor to move freely, depending on the force of the spring, upon impact with an object with a mass greater than a certain threshold so that, in a second gate position closing the opening at the distal end of the body, the system is prevented from being damaged.

Advantageously, an embodiment comprising a first lockable door and a second hinged door allows for differentiated control of the intermediate steps in the analysis process of a container.

In one embodiment, the operation of both gates is independent, providing greater versatility in the configurations that the system can adopt. Preferably, during the analysis process performed by the detection module, both gates would remain fixed or locked, closing both openings: the one at the docking interface and the distal end of the receiving chamber.

In one embodiment, the first and second actuating means are coupled to act together by a rocker-type element.

In a more particular embodiment, the first and second actuating means are coupled by a rocker system driven by a single motor, thus allowing the movement of the first and second gate to be controlled synchronously.

In one embodiment, the mechanical module comprises a frame and an ejector mechanism. The frame is coupled to the main body and configured to provide support.

The ejector mechanism comprises first actuating means and second actuating means, wherein said first actuating means comprise a first arm, and wherein said second actuating means comprise a second arm, said first and second arms being articulated by means of a connecting rod.

The second arm is integrally connected to the second gate, which acts as a container-retaining element inside the receiving chamber. Said second arm will reversibly move the second gate from an initial position where it blocks the opening at the distal end of the receiving chamber to a final position where it unblocks said opening, allowing passage through the opening to be cleared.

In this embodiment, the main body additionally comprises a slot arranged along a predetermined length in a lower section thereof, according to the direction of gravity, which connects the interior of the receiving chamber with the ejector mechanism. The ejector mechanism additionally comprises a blade, preferably in the form of a paddle or rib, configured to pass through said slot arranged in the main body, to access the interior of the receiving chamber and push a container housed therein toward the opening at the distal end. The movement of the second folding gate by means of the second arm toward its final position is coordinated with the movement of the blade, such that after actuating the ejector mechanism, the blade facilitates the release of the container into the container.

Advantageously, the frame and ejector mechanism comprising the first and second actuator means and the connecting rod provide support, structural coupling, and mechanical interaction capability to the user. In particular, the first arm of the first actuator means extends toward a proximal end such that, in an operative configuration, it projects a distance toward the exterior of the system and the container through the coupling interface. Said proximal end of the first arm forms a lever that allows the ejector mechanism to be actuated, the first arm being connected at its opposite end to a proximal end of the connecting rod.

In one embodiment, the lever segment exposed to the user through the docking interface describes a downward linear pull path or travel defined by a guide slot or groove located in the docking interface of the system.

In order to communicate the actuation movement of the first arm to the second arm by means of the connecting rod, the second arm is articulated to a distal end of the connecting rod by means of the end of the second arm opposite to the end by which it is integrally connected to the second folding gate. In particular, one of the two ends of the connecting rod is configured to move along a guide arranged in the frame by means of the actuation of the lever, and thus, the displacement exerted by a user on the first arm through the lever segment is transferred to the second arm through its connection with the distal end of the connecting rod, in such a way that it allows the second folding gate to be moved from the initial position where it blocks the opening of the distal end of the receiving chamber to the final position in which it allows the passage of a container through said opening.

At the same time, this opening movement of the receiving chamber by means of the movement of the second folding gate causes the rotation and consequent sweeping movement of the leaf, which is integrally connected to the second arm, inside the receiving chamber, through the slot provided in the main body.

In one embodiment, the coupling interface of the mechanical module comprises a plate that is attached to the opening of the container by means of detachable fixing means, such as by means of screws.

In one embodiment, the plate additionally comprises at least one locking tab arranged on the perimeter edge configured to project a distance from said perimeter edge, preventing the main body of the mechanical module from sliding through the opening of the container.

In one embodiment, the receiving chamber defined by the main body of the mechanical module has a substantially cylindrical structure extending along a longitudinal direction and inclined to promote falling under the action of gravity along the cylindrical receiving chamber and along the system.

In one embodiment, the main body comprises a ridged region at its distal end.

Advantageously, the presence of said grooved area helps prevent vandalism and negligent use of the detection system. In particular, said grooved area prevents an attempt to unlawfully remove a container from inside the container to the outside by placing said grooved area in the path of the container's return from inside the container, for example, by using a rope attached to the container.

In a particular embodiment, the grooved area of the main body is a serrated edge.

In one embodiment, the distance between incisions of the serrated edge is smaller than a characteristic dimension of a lightweight package to be deposited in the container.

In a particular embodiment, the serrated edge is formed by alternating projections with incisions, both substantially V-shaped.

According to this embodiment, this geometry will provide an abrupt and tortuous profile, making it difficult for a lightweight container to return from the inside of the container to the inlet opening, by any means, especially if the container is tied to some type of rope-like element. In this case, in an attempt to carry out an illicit extraction operation in which a container is being extracted from the inside of the container, said rope would be inserted into one of the recesses of the serrated edge, and the container would be caught in the body of the grooved area.

In a particular embodiment, the striated area covers only a portion of the lower half of the distal end of the main body, the lower half being that intended to substantially come into contact, by gravity, with the container as it passes through.

According to this embodiment, said ridged area, like the main body, has a substantially cylindrical structure projecting a certain length from the distal end of the main body, but encompassing only a certain circular sector around the point of lowest height according to the direction of gravity. Thanks to this structure and arrangement of the ridged area, contact of the free container with the ridged area is ensured as it falls along the main body, and, at the same time, obstruction is ensured by the interposition of said ridged area, preventing upward movement or extraction from the interior of the container, for example, by using a string tied to the container.

Advantageously, a system configuration where the grooved area is designed considering only the portion of the main body that will be in contact with the container as it falls into the container allows for optimization of the system's mechanical structure. This means reducing the overall weight, providing a more compact geometry, and saving on manufacturing materials.

In one embodiment, the cylindrical section of the receiving chamber is 140mm in diameter.

In one embodiment, the main body comprises a transparent section configured to allow the first sensor means to view a container disposed inside the receiving chamber.

In one embodiment, the transparent section is composed of methacrylate.

In one embodiment, the transparent section is arranged along a portion of the uppermost part of the receiving chamber, according to the direction of gravity.

In one embodiment, the main body of the mechanical module comprises a housing configured to house the elements of the electronics module and the power module.

In one embodiment, the second sensor means configured to detect a metallic composition of a container comprises a coil wound around the main body of the mechanical module along at least a cross-sectional portion thereof.

In one embodiment, the wound coil is made of copper and is powered to generate a magnetic field oscillating around 6kHz, which makes it possible to differentiate between aluminum (field disturbance above 6kHz) and ferromagnetic steel (field disturbance below 6kHz).

In one embodiment, the section comprising the wound coil is a section proximate the distal end of the main body of the mechanical module.

In one embodiment, the third sensor means configured to detect a polymeric composition of a container comprise a NIR type infrared sensor.

In one embodiment, the NIR type infrared sensor is located in a section close to the distal end of the main body of the mechanical module, facing towards the interior of the receiving chamber.

In one embodiment, the power module comprises at least one battery. The battery is preferably a LiFePO4 battery.

In one embodiment, the power module comprises at least one solar panel, preferably a flexible solar panel.

Flexible solar panels, unlike conventional rigid panels, use materials that withstand some deformation to allow them to adapt to surfaces with certain curvatures. This way, the solar panels will have greater adaptability and can be integrated directly into the container, on virtually any of its exterior surfaces (and even on the user interaction interface), thus avoiding damage by occupying certain spaces that may be subject to manipulation, for example, during waste collection processes by local work teams. In these cases, the container is lifted and subsequently emptied, generally by mechanisms implemented in large collection trucks, which poses a risk of impacts or jolts that could cause the rigid panels to break.

Furthermore, flexible panels can incorporate a regulator that facilitates the integration of the assembly and its subsequent handling for repairs and maintenance. Furthermore, the appearance and structure of the integrated assembly will be more compact, improving the aesthetic perception of the assembly and potentially acting as a deterrent to misuse.

In an embodiment where there are at least one battery and at least one solar panel in the power module, the energy obtained by the solar panel may be used to recharge the battery.

Advantageously, the system according to this embodiment will have improved autonomy and greater flexibility for urban deployment in remote areas, as it will remain properly powered to perform all functions requiring electricity without needing to be connected to the power grid.

In a second inventive aspect, a container is defined that comprises a container typology detection system attachable to a container according to any of the embodiments of the first inventive aspect.

In a particular embodiment, the container is a selective collection container for light packaging located on an urban road.

In a particular embodiment, the container to which the detection system is attached is a reverse vending machine.

All features and/or method steps described herein (including the claims, description and drawings) may be combined in any combination, except for combinations of such mutually exclusive features, provided that it is within the scope of the appended claims.

Figure 4 This figure shows an example of a packaging typology detection system coupled to a container.

Detailed exposition of the invention

Figures 1a and 1b show a perspective view of the front and rear parts, respectively, of an example of an embodiment of a system (100) for detecting packaging typology that can be attached to a container (200) according to the invention. The front part is defined as the part of the system (100) that is accessible to a user for inserting a package and that will coincide with the proximal end (114) of the main body (113) of the mechanical module of the system (100). The rear part corresponds to the distal end (117) of said main body (113).

Said mechanical module of the system (100) is introduced, together with all the mechanical elements of the system (100) into the interior of a container (>200<) through an opening thereof, which opening may be the same to which the>system (100) is subsequently coupled for its fixation with respect to the container (200). To be fixed to said opening,<the mechanical module comprises a coupling interface (not shown in figures>1<a and>1<b) configured to> be fixed in a detachable manner to the opening of the container (200). The mechanical module comprises, in turn, an <opening (>112<) configured to allow access of containers to the interior of the system (>100<) to proceed with their analysis and subsequent release into the interior of the container (>200<) to which the system (>100<) is coupled in operational configuration.

A main body (113) can be seen which, in the final assembly configuration, would be integrally connected via its proximal end (114) to said coupling interface. The main body (113) contributes to giving <shape to the system (> 100 <) and, in a preferred embodiment, is completely inserted through the opening of the container (> 200 <), projecting into the interior of the same from the opening (> 112 <) of the coupling interface,> thus defining a receiving chamber (115). Said receiving chamber (115) configures the housing where a <user deposits the containers, which are temporarily retained after accessing the interior of the system (> 100 <) through the opening (> 112 <) while the detection and classification actions are carried out.>

For the release of the containers into the container (200), in figure 1b an opening (116) is observed located at the distal end (117) of the main body, said opening (116) being oriented towards the interior of the <container (>200<) in operational configuration, that is, with the system (>100<) coupled to a container (>200<).>

In addition to the elements of the mechanical module, which give shape to the system (100) and serve as a physical interface for the coupling of the system (>100<) to the container (>200<) and for the accommodation and support of the containers, it can be observed that the system (100) comprises a plurality of sensor elements (121, 122, 123) that make up the detection module.

In particular, in Figure 1a, first sensor means (121) are observed mounted on a support structure coupled to the upper part of the main body (113). Said first sensor means (121) are configured to detect at least one product identification code arranged on a package, such as a barcode or a QR code. In addition, it is observed that the main body (113) comprises a transparent section located immediately below the first sensor means (121). Said transparent section is mainly composed of methacrylate, and is configured to visually communicate the first sensor means (131) with the interior of the receiving chamber (115).

In both Figure 1a and Figure 1b, second sensor means (122) are also observed, configured to detect a metallic composition of a container. In particular, the second sensor means (122) of the embodiment shown comprise a copper coil wound around the main body (133) of the mechanical module along a cross-sectional portion thereof. As can be seen, said cross-section corresponds to the section close to the distal end (117), where the container will be housed and kept at rest, once it is inside the system (100), for analysis. More particularly, the wound coil is powered to generate <a magnetic field oscillating around> 6 <kHz, which allows differentiating aluminum (field alteration above> 6 <kHz) from ferromagnetic steel (field alteration below> 6 <kHz).>

Finally, also in Figure 1a and Figure 1b third sensor means (123) are observed coupled to a lower part of the main body (113). Said third sensor means (123) are configured to detect a polymeric composition of a container, such as PET. In particular, the third sensor means (123) of the embodiment shown comprise an NIR type infrared sensor, located in the same manner as the second sensor means (122), that is, in a cross section close to the distal end (117), where the container will be housed and kept at rest, once it is inside the system (100), for its analysis. Additionally, in the same manner as occurred with the first sensor means (121), it is observed that the main body (113) comprises an opening, or transparent portion, that allows access and communicates the third sensor means (123) with the interior of the receiving chamber (115) to analyze the polymeric composition of a deposited or received container.

Finally, in Figure 1a a second opening is observed in the upper part of the main body (113) of the mechanical module that gives access to the interior of the receiving chamber (115). In particular, in this embodiment the detection module additionally comprises image capture means (not shown), which preferably comprise a wide-angle camera with artificial lighting, such as a flash type, to obtain photographs of the containers inside the receiving chamber (115).

Said image capture means may be coupled together with the first sensor means (121) to the support structure. Said support structure on which the first sensor means <(>121<) are mounted is foldable, such that it allows the first sensor means (>121<) and the image capture means to be located close to the distal end (117), orienting at the same time the detection area of the first sensor means (121) and the image capture means towards the opening (112) of the receiving chamber (115). In this way, a user can manually present the container in the vicinity of said opening (112) for a first recognition stage, both of code and container geometry, to subsequently release the container into the interior of the system (100) for the detection of its metallic and polymeric composition. In relation to said <first recognition stage in the vicinity of the opening (>112<), in a modified embodiment, alternative to that shown in figures>1<a and>1<b, the detection area of the first sensor means (>121<) is oriented towards>the outside of the container in which the system (100) is installed. In particular, the first sensor means (>121<) communicate, from their location, with the outside of the container through a transparent section located in a coupling interface such as that shown in figure>2<a.>

In addition to the elements comprised in the mechanical and detection modules, respectively, in Figure 1b it can be seen that the system (>100<) comprises an electronics module which, in turn, comprises data processing means (131) in the form of a printed circuit board (PCB) coupled to the main body (113) next to the coil that forms part of the second detection means (122). In particular, the elements of the detection module, that is, the first (121), second (122) and/or third (123) sensor means are configured to generate a data signal with the detected information relating to the type of container introduced inside the system (100). Said signal is sent to said data processing means (131) for subsequent processing.

In the exemplary embodiment shown in Figures 1a and 1b, the data processing means (131) are in communication with storage means that also form part of the electronics module, and that comprise a database of packaging typology, classified based on: product identification codes, and/or the metallic composition of the packaging, and/or the polymeric composition of the packaging; and wherein the data processing means are configured to determine at least one packaging typology by comparing the information received from at least one of the sensor means in the form of a signal with the database of packaging types stored in the data storage means.

On the other hand, the electronic module of the embodiment shown in Figures 1a and 1b comprises wireless communication means integrated in the printed circuit board (PCB) configured to establish wireless communication between the system (100) and a remote server. In this way, the system (100) has the capacity to share information related to the parameters of the different container analyses carried out within the system (100). In particular, the system (100) shown in Figures 1a and 1b provides the remote server with the following information on the typology of the containers:

- product identification code;

- metallic composition of the container;

- polymeric composition of the container.

More specifically, the system (100) also wirelessly transmits images captured by the wide-angle camera to the remote server. This enables the remote server to process the images using “Deep learning” machine learning methods.

Finally, in both figures 1a and 1b a power supply module (140) is observed, arranged in the same section in which the data processing means (131) are located, that is, on the coil of the second sensor means (122) wound on the main body (113), but with another angular position. In particular, the power supply module shown comprises a battery configured to provide power to the elements comprised in the detection module and in the electronics module.

Although in the embodiment shown in Figures 1a and 1b three different sensor means are included, in other <embodiments the system (>100<) may include a different number of sensor means.>

Figures 2a and 2b show a perspective view of the front and rear, respectively, of an exemplary embodiment of a container typology detection system (100) coupled to a container (200). In the exemplary embodiment shown, unlike what occurred with the example shown in Figures 1 a and 1 b, the mechanical module of the system (100) shows details of a coupling interface (111) configured to be detachably fixed to an opening of the container (200). Said coupling interface (111) is coupled to the container (200) by means of screws, is integrally connected to the proximal end (114) of the main body (113), and comprises an opening (112) for inserting containers into the system (100). In particular, <the coupling interface (>111<) has an essentially rectangular structure, with rounded edges, the perimeter of which defines an interface area sufficient to overcover the contour of the container opening<(>200<), such that the excess portion of the coupling interface (>111<) extending from the contour of the container opening (>200<) allows the coupling interface (>111<) to be correctly framed over said>opening by contacting the surface surrounding the opening of the container (200). In this way, <access to the interior of the container (>200<) through said opening is prevented in any way other than through the opening (>112<) of the coupling interface (>111<) itself.>

In Figure 2b it can be seen that, on the inside of the coupling between the coupling interface (111) and <the container opening (>200<) there are locking tabs arranged on the inside face of the rectangular plate in>the perimeter of contact with the original opening of the container, preferably separated at the upper and lower edges of said perimeter. Said tabs project a distance to prevent the extraction, by sliding, of the main body (113) through the container opening (200).

In both Figure 2a and Figure 2b, the receiving chamber (115) defined within the system (100) has a substantially cylindrical structure along the longitudinal direction of the main body (113). In particular, in the example shown, the receiving chamber (115) has a cylindrical section of 140 mm in diameter, which is sufficient to ensure the passage of light containers.

Additionally, it is observed that, in the configuration coupled to the container (200), the main body (113) and, therefore, the receiving chamber (115), has a downward inclination with respect to the plane defined by the coupling interface plate (111) coupled to the opening of the container (200). This inclination favors the natural fall of the containers introduced into the interior of the system (>100<), under the action of gravity, along the> receiving chamber (115).

In both Figure 2a and Figure 2b it can be seen that the main body (113) of the mechanical module comprises a housing in the form of a trapezoidal protuberance. Said housing protects all the sensitive elements of the detection module, the electronics module and the power supply module.

In Figure 2b it can be seen that the mechanical module comprises a folding gate (119) configured to retain a container inside the receiving chamber (115) in order to facilitate its analysis by the elements of the detection module. In the same way, under certain conditions, said folding gate (119) will release said container allowing its exit from the system (100) through the opening (116) of the distal end (117) of the main body (113). The operation of the gate (119) is controlled by actuating means (not shown in the image) controlled in turn by the data processing means. In particular, the data processing means are configured to control said actuating means according to any of the following instructions.

On the one hand, if a container is inside the receiving chamber (115) being analyzed by the elements of the detection module, the data processing means will prevent the closing of the gate (119) in such a way that the container is retained inside the receiving chamber (115) until its analysis is completed.

On the other hand, if a container is inside the receiving chamber (115), having completed its analysis, that is, having completed the determination of the typology of the introduced container, the data processing means will order the actuating means to fold down the gate (119) to allow the release of the <container from the inside of the system (>100<) to the inside of the container (>200<).>

Although no graphic details are shown, the system (100) of the example of Figures 2a and 2b also comprises a user interaction module. Said user interaction module comprises a user interaction interface located on the docking interface plate (> 111 <), and facing away from the opening of the container (200), to facilitate access to users. The user interaction module also comprises user authentication means configured to wirelessly recognize a user. In particular, in one embodiment, a user identifier will be interrogated wirelessly, which may be a portable device with NFC and/or Bluetooth® technology, such as a card or a smart mobile phone. Preferably, the user interaction module also comprises information presentation means to provide the user with information related to the process of identifying, receiving and analyzing the container that is introduced into the interior of the system (100). In addition, there may be labeling on said interface that indicates to the user where to bring their identifier.

Although no graphic details are shown in Figures 2a and 2b, in a preferred embodiment, the information presentation means comprise a touch interaction screen, as well as LED type light indicators and/or speakers for the emission of acoustic signals.

In Figure 3, in a complementary manner to the example shown in Figures 2a and 2b, details of a lockable gate (118) arranged in the opening (112) that gives access to the interior of the receiving chamber (115) of the system (100) are shown. In particular, the lockable gate (118) is shaped like a flat disc, made of polymeric material, and is configured to move in a plane perpendicular to the direction of entry of containers, describing a circular path pivoting around a point, to slide from a rest position in <which it prevents the passage of containers through the opening (>112<) of the coupling interface (>111<) of the mechanical module to the interior of the system (>100<), to a displaced position in which it allows said passage of containers to the interior of the system (>100<).>

Also in this case, the operation of the lockable gate (118) is controlled by actuating means (not shown in the image) which are in turn controlled by the data processing means. In particular, the data processing means are configured to control said actuating means according to one of the following instructions.

If a container is inside the receiving chamber (115) being analyzed by the elements of the detection module, the actuating means will keep the gate (118) blocked, preventing it from sliding out of its resting position, in such a way that the opening (112) is completely blocked and the passage of containers into the receiving chamber (115) is prevented.

If the presence of a container is not detected inside the receiving chamber (115), the actuating means will unlock the gate (118), causing it to slide out of its resting position, describing a circular path, in the same way as a peephole, to allow the passage of a container into the system<(>100<).>

If a user's registration is detected by the user identification means, the actuating means will unlock the gate (118) to allow the passage of containers into the receiving chamber (115).

Figure 4 shows a perspective view of a container typology detection system (100) coupled to a selective collection container (>200<) of the type located on the street, more particularly a container (200) for recycling containers. It can be seen that said container (200) comprises an additional opening apart from the opening (>112<) arranged in the coupling interface (>111<) of the system (>100<), such that the conventional deposit of containers is facilitated, in the event of not wishing to introduce the container into the container (>200<) through the system (>100<).

Additionally, the presence of solar panels (201) can be observed at the top of the container. These solar panels are flexible solar panels and are connected to the power supply module of the system (100).
