Description

[Technical field]

[0001] The present invention relates to an autonomous vending system and components for transforming a refrigerator or cabinet into an autonomous Point Of Sales (POS) with artificial intelligence systems (machine learning and computer vision), including the placement and attachment of multiple video cameras with novel retractable mounts. More specifically, the present invention relates to a system that allows a customer to remove items from a refrigerator or cabinet without checking out, while automatically updating inventory and billing data. [Background technology]

[0002] There are several systems for the sale and provision of consumer products and goods, such as beverages and other foodstuffs, which include cabinets and / or refrigerators in which the products are stored in a conditioned state that makes them accessible to the consumer for immediate consumption upon purchase. To avoid the presence of operational or monitoring personnel, such systems are equipped with video cameras that film not only the cabinet or refrigerator at all times, but also all the goods contained therein. However, cameras added to the cabinet or refrigerator, whether external or internal, are an obstacle. The use of one or more chambers on the outside of the refrigerator creates a volume that cannot be adequately transported in containers from the factory, and if installed inside, they take up space that is useful for the storage of products.

[0003] As one type of camera-based vending machine or vending system, China Patent Application Publication No. 110136328 discloses an AI (artificial intelligence) intelligent vending cabinet based on dynamic visual recognition. The vending cabinet is communicatively connected to a cloud server. The vending cabinet is composed of a cabinet body with at least one shelf, a camera arranged on the cabinet body, and a control module connected with the camera and a wireless transmission module, the cloud server includes a dynamic visual recognition algorithm processing module and a storage area, the camera captures a video of the entire process of an object exiting the cabinet body, the video is uploaded to the cloud server via the wireless communication module, the video processing calculation recognition is performed by the dynamic visual recognition algorithm, and the recognized result is transmitted to a user payment terminal via a network for fee deduction.

[0004] There are also system solutions using refrigerator scales and RFID systems, but the operation, installation and maintenance costs are very high. There are also other solutions using cameras, such as the aforementioned CN110136328, but they are not more simplified and embedded systems like the present invention's system with compact hardware that can be embedded in the side, so such systems in the prior art are not at a higher level compared to the solution and novelty of the present invention. Furthermore, the prior art does not offer the low operation and installation costs that the present invention offers, due to the long life of the parts, with only corrective maintenance (if necessary). Summary of the Invention

[0005] It is therefore an object of the present invention to provide a new stand-alone, consumer-operable POS system that includes, among other advantages, a retractable arrangement of one or more video cameras that are mounted or embedded in the frame of a cabinet or refrigerator without occupying both the exterior and interior volume of the cabinet / refrigerator.

[0006] The invention also provides a fully autonomous system managed by artificial intelligence where the consumer can select the product they want, pay for it automatically, keep it and if they regret it they can return it and take something else instead, all their actions are recorded and the operation is completed successfully.

[0008] The present invention provides a system for the consumption, sale and supply of consumer products, which can be operated by the same consumer when purchasing a desired product or range of products, comprising one or more recessed video cameras for example in a cabinet system or refrigerators such as Grab & Go refrigerators.

[0009] According to figures 1 to 16, the invention consists of a cabinet / refrigerator 1 for the automatic sale or sale of various products, comprising side walls 2, a top cover 3, an internal housing 4 compartmentalized for the various products to be sold, a frame 5 defined by an opening periphery of said cabinet 1, and a pivotable closing door 6. Said cabinet 1 may be provided with means or power sources enabling the operation of the respective cooling means and all the systems or components that are part of it, which are widely known and will not be described in detail.

[0010] As mentioned in the prior art section, such cabinets can be equipped with RFID or dynamic vision technology. Unlike the prior art, particularly CN110136328, the present invention provides a retractable camera that is only activated when the user opens the door 6. That is, see Figs. 1-5, when the door is closed, the camera is retracted and "hidden" within the cabinet. Because the retractable camera is located inside each part of the cabinet, it does not take up external and internal physical space that could be used for storage, and does not interfere with movement or handling of the cabinet.

[0011] Here, the present invention provides at least one retractable side chamber 7 arranged on the side of said cabinet / refrigerator 1. According to Fig. 4, Fig. 8 and Fig. 9, said retractable side chamber 7 consists of an external metal plate or housing 8 fixed or embedded in a part 72 of the side wall of the cabinet / refrigerator 1 via respective fastening means such as screws, bolts, etc., and remains within the cross section or width bounded by the frame 5 so as not to generate protrusions that complicate transportation or occupy physical space that may be used for other purposes. Similarly, said side chamber 7 consists of an internal linear bearing 9 attached inside said external plate 8 via respective screws 10. Said internal linear bearing 9 may be a SCS10UU type bearing, but this is not a limitation of the present invention.

[0012] On the other hand, it comprises at least one external support 11 attached to the outer part of the external plate 8 via respective screws 12, said external support 11 comprising at least one external linear bearing 13, which may be a LM6UU type bearing, but this is not limiting for the invention. On the other hand, said retractable side chamber 7 comprises at least one rod 14 acting as a working piston in cooperation with a spring 15, one end of which is attached to the internal linear bearing 9 attached inside the external plate and held by an external lock 16, and the other end of which is connected to a linear rod support 17, which may be a SHF10 type rod support, but this is not limiting for the invention.

[0013] As mentioned above, the side chambers 7 are retractable and hidden within the "thickness" of the cabinet. To achieve this, at least one movable piston support 18 is provided, on which the linear rod supports 17 are attached via respective screws 19. Also, as best shown in FIG. 4, at least one secondary rod 20 is provided, attached between the external linear bearing 13 and an orifice 21 of the movable piston support 18, and has a surface 22 that contacts the inside of the door 6. Thus, when the door 6 is closed (see FIG. 4), the piston support 18 is retracted as is the rod 14, in conjunction with the spring 15, which is held in a compressed state, due to its contact against the surface 22. When the door 6 is opened (see FIG. 6), the spring 15 returns to its natural state, displacing the piston support 18 "outwards", the side chamber 7 is in its working position, and we start with the record of what happened. It is emphasized that both the rod 13 and the secondary (auxiliary) rod 20 move linearly in an internal linear bearing 9 -external linear bearing 13 respectively, and both perform the function of the "piston or drive shaft" of the piston support 18.

[0014] On the other hand, there is provided at least one chamber support 23 attached to the piston support 18 via respective screws 24, and at least one chamber 25 attached to the chamber support 23 via respective chamber nut assemblies 26 and screws 27. The chamber support 23 comprises a metal plate structure containing an orifice for the passage of the chamber 25 and bent in such a way as to create a certain inclination angle for the chamber 25. The piston support 18 is designed to contain and protect the chamber 25.

[0015] It is emphasized that the retractable side camera 7 is configured as a USB 3.0 side camera and is arranged at an angle of about 30° to 35° to its X-axis and about 110° to 130° to its Y-axis. Preferably, but not limiting to the invention, the retractable side camera 7 is arranged at an angle of 33° to the X-axis and 120° to the Y-axis. Thus, when a user opens the door 6, the bar 13-spring 14 "pushes" or displaces the piston support 18 outward to position the camera 25 in its operating position and start recording or filming the selling or replenishing operation. When the selling or replenishing operation is finished, the door closes and moves into the cabinet in contact with the piston support 18, hiding the camera.

[0016] The present invention further comprises a retractable upper central chamber 28, which is located within the upper central portion 73 of said cabinet / refrigerator 1 and is concealed within a space or width bounded by the frame 5 so as not to protrude beyond the height of the cabinet. According to Figs. 5, 7 and 10-12, said retractable upper central chamber 28 comprises an external metal plate or casing 29 fixed to the inside of the top cover 3 of the cabinet / refrigerator 1 via respective fastening means such as screws. Similarly, said upper central chamber 28 comprises an internal linear bearing 30 attached to the inside of said external plate 29 via respective screws 31. Said internal linear bearing 30 may be a SCS10UU type bearing, but this is not a limitation of the present invention.

[0017] On the other hand, it comprises at least one external support 32 attached to the outside of said external plate 29 via respective screws 33 and nuts 34, said external support 32 comprising at least one external linear bearing 35, which may be a LM6UU type bearing, but this is not limiting for the invention. On the other hand, said retractable upper central chamber 28 comprises at least one rod 36 cooperating with a spring 37, one end of which is attached to said internal linear bearing 30 attached to the inside of said external plate and held by an external lock 38, and the other end of which is connected to a linear rod support 39, which may be a SHF10 type rod support, but this is not limiting for the invention.

[0018] As mentioned above, the upper central chamber 28 is retractable and hidden, as are the side chambers 7. To achieve this, at least one movable piston support 40 is provided, on which the linear rod supports 39 are attached via respective screws 41. Also, at least one secondary rod 42 is provided, which is attached between the external linear bearing 35 and an orifice 43 of the movable piston support 40. To film or record what happens when the door 6 is opened, the invention provides at least one camera 44 attached to the piston support 40 via a respective support-nut-camera assembly 45 and screw 46. The piston support 40 comprises a metal plate structure bent to provide an inclination angle for the camera 44, with an orifice for the camera 44 to pass through.

[0019] Likewise, a chamber protector 47 is provided, attached to said piston support 40 by respective screws 48 and having a surface 49 in contact with the inside of the door 6. Thus, when the door 6 is closed (see FIG. 5), in contact with the surface 49, the piston support 40 is retracted as well as the rod 36 with the spring 37 kept in a compressed state. When the door 6 is opened (see FIG. 7), the spring 37 is released and returns to its natural state displacing the piston support 40 "outwards", positioning the camera 44 and starting to record what happens. The rod 36 - secondary rod 42 move linearly by the internal linear bearing 30 - external linear bearing 35 respectively, and perform the function of the "axis or driving piston" of the piston support 40.

[0020] Meanwhile, the retractable upper central compartment 28 contains a USB 3.0 side camera and is angularly positioned between about 20° and 30° relative to its X axis. Preferably, but not limiting to the invention, the upper central camera 28 is positioned at an angle of 26° relative to its axis X. Thus, when a user opens the door 6, the bar 36-spring 37 "pushes" or displaces the piston support 40 outward, placing the camera 44 in its operating position and beginning to record or film the vending or refilling operation. Once the vending or refilling operation is completed, the door 6 closes, contacting the face 49 of the camera protector 47 and displacing the assembly into the cabinet, hiding the camera.

[0021] In order to cover a wider field of view during recording and thus provide a better service and thus avoid possible accidents, the present invention further comprises a retractable upper chamber camera 50, which is located in the upper part 74 of the cabinet / refrigerator 1 and is hidden within the space or width defined by the frame 5 so as not to protrude beyond the height of the cabinet. According to Figs. 5, 7, 13 and 14, the retractable upper chamber 50 consists of an external metal plate or casing 51 fixed to the inside of the top cover 3 of the cabinet / refrigerator 1 via respective fixing means such as screws. Similarly, the upper chamber (upper side or upper lateral) 50 includes an internal linear bearing 52 attached to the inside of the external metal plate 51 via respective screws 53. The internal linear bearing 52 may be a SCS10UU type bearing, but this is not a limitation of the present invention.

[0022] On the other hand, it comprises at least one external support 54 attached to the outside of said external plate 51 via respective screws 55 and nuts 56, said external support 54 comprising at least one external linear bearing 57, which may be a LM6UU type bearing, but this is not limiting for the invention. On the other hand, said retractable upper chamber 50 comprises at least one bar 58 together with a spring 59, one end of which is attached to said internal linear bearing 52 attached to the inside of said external plate and held by an external lock 60, and the other end of which is connected to a linear bar support 61, which may be a SHF10 type bar support, but this is not limiting for the invention.

[0023] As mentioned above, the upper camera 50 is retractable and concealed, as are the upper camera 7 and the upper central camera 28. To achieve this, at least one movable piston support 62 is provided to which the linear rod support 61 is attached via respective screws 63. Also, at least one secondary (secondary) rod 64 is provided, which is attached between the external linear bearing 57 and an orifice (not shown) of the movable piston support 62. To perform the filming or recording of what happens when the door 6 is opened, the present invention provides at least one camera 65 attached to the piston support 62 via a respective assembly of a camera nut 66 and a screw 67. The piston support 62 includes an orifice for the camera 65 to pass through and includes a bent metal plate structure that determines a constant tilt angle for the camera 65.

[0024] Similarly, it comprises a chamber protector 68, attached to said piston support 62 via respective screws 69 and presenting a surface 70 in contact with the inside of the door 6. Thus, when the door 6 is closed (see FIG. 5), in contact with the surface 70, the piston support 62 is retracted as well as the rod 58 in conjunction with the spring 59, which is kept in a compressed state. When the door 6 is opened (see FIG. 7), the spring 59 returns to its natural state, displacing the piston support 62 "outwards", allowing the recording of an event. The rod 58 - secondary (secondary) rod 64 move linearly, respectively, in the internal linear bearing 52 - external linear bearing 57, and perform the function of the "axis or driving piston" of the piston support 62.

[0025] Meanwhile, the retractable upper camera 50 is composed of an upper USB 2.0 camera and is positioned at an angle of about 10° to 20° to its X-axis and about 70° to 80° to its Y-axis. Preferably, but not by way of limitation, the retractable upper camera 50 is positioned at an angle of 15° to its X-axis and 75° to its Y-axis. Thus, when a user opens the door 6, the bar 58-spring 59 "pushes" or displaces the piston support 62 outward, positioning the camera 65 in its operating position and starting to record or photograph the vending or restocking operation. When the vending or restocking operation is completed, the door 6 closes and contacts the surface 70 of the camera protector 68, moving the assembly into the cabinet and hiding the camera.

[0026] Thus, by strategically placing the three cameras 7, 28, 50 in different parts of the cabinet, it covers a greater visual width and height, not only providing a better shopping and restocking experience but also drawing attention to any incidents or altercations that may occur.

[0027] Thus, a retractable video camera system or arrangement is embedded in a frame within the wall of a refrigerator or cabinet. Each camera has a metal housing with a spring system to which a USB camera is attached. The system is attached with screws and its function is to capture images for settling transactions with the vending system of the present invention. Each camera is connected to a CPU via respective data and power cables. The CPU is connected to a server on the cloud. The server is controlled to generate various instructions to the CPU for opening the door, as well as for generating sales tickets, low stock alerts, refills, theft alerts, etc., as best shown in Figures 15 and 16.

[0028] Thus, the system of the present invention is activated when a user unlocks a cabinet or refrigerator door that has been closed by the intelligent lock system 71. When the door is opened, see Figs. 6 and 7, the rod-spring assembly of each camera pushes the piston support, which puts the camera at a specific angle. Each camera is in a protruding position relative to the refrigerator frame, allowing it to take images at a specific angle. When the refrigerator is closed, the door pushes the system back inwards, and it can only retract outwards relative to the refrigerator frame when the refrigerator door is open. In this way, the chambers do not take up any usable space when they are not in use, see Figs.

[0029] These metal housings and cameras are preferably positioned at three different points and angles, but more preferably, are positioned between the frame walls to cover a larger field of view, as previously described.

[0030] Thus, the present invention provides for the design and development of components that are installed to convert a refrigerator or cabinet into a self-contained outlet. As mentioned above, the present invention includes a CPU (not shown) to which the retractable side camera 7, the top center camera 28, the top side camera 50, and other systems such as an intelligent lock 71, which can be an electronic padlock on the door, as well as different universal plates (external embedded systems) that allow the operation of the refrigerator with the intelligent systems. All the electrical and electronic components are controlled by the CPU and driven by a power supply.

[0031] Equipment Installation Process To install the device, the firmware (specialized software that runs on the CPU) has a web interface that allows the installation technician to perform any necessary operational tests and test the connection to the installation site's WiFi network.

[0032] Purchase Process (Standalone POS Function) The system of the present invention allows a user to remove items from a refrigerator or cabinet and pay for them without going through a cash register. The transaction basically consists of a person (user) scanning a QR code with a web application (app) developed by the system provider and going through a registration process within the app. Once this registration is completed, the app unlocks the refrigerator or cabinet door and releases the electric lock provided by the system supplier and possibly the refrigerator manufacturer. This lock (see Figure 16) is commanded by a CPU (intuitive embedded system) that is connected to the Internet via WiFi and contains an interface board connected to the system provider's API (Application Program Interface) on the cloud via the Internet. When the refrigerator door is opened, the CPU automatically sends a signal for the camera to start recording the transaction and records on video the actions the user makes with the refrigerator or cabinet. After the user selects or does not select an item, he closes the door and, with the help of a proximity sensor that detects that the door is closed, sends a signal to the CPU to end the video recording. These videos are sent to the system provider's server and temporarily stored to be updated in the system's transaction software.

[0033] The program is based on computer vision and machine learning in the field of artificial intelligence, and processes the video and creates tickets to automatically charge the user with the credit / debit card initially registered in the web application, or generates warnings if, for example, there is an attempt to hide an item or the video does not show the item correctly. Later, an employee of the establishment reviews them and allows the transaction to be processed correctly. This review process is carried out in a web-based dashboard program(*) provided by the system provider, with different user levels: operator, customer and manager. In this “dashboard”, the customer can visualize the transaction and all the data that informs him about the user who made the purchase, the product purchased, the store where it was sold, as well as the real-time inventory of the machines (refrigerators, cabinets) and their various conditions. A dashboard is an information management tool that monitors, analyzes and visually displays key performance indicators (KPIs), metrics and key data to track the status of a company, a department, a campaign or a specific process.

[0034] Refrigerator and freezer restocking process In this process, through a web or native application, employees who wish to restock a refrigerator or cabinet can initiate this action, scan a QR code to manually insert the item to be added, take a full photo of the front of the refrigerator along with the item for records, and send them to the system server to update the dashboard data.

[0035] In this way, the purchasing user is provided with a shopping experience that does not require paying at a "cash register" or waiting in a long line. Similarly, the seller user can easily know the inventory of the product in real time. At the same time, since it is a retractable camera that does not occupy physical space that can be used for other purposes, it is easy to handle and move. Again, since the camera is hidden in the cabinet and retractable, it only works when the door is opened. When the door is opened (see Figures 6 to 7), the spring provided in each camera system pushes out the piston support, each camera is positioned at a predetermined angle, and recording of the sales transaction begins as described above. When the purchasing user closes the door (see Figure 5), the piston support is retracted at the same time as the spring is compressed, the camera recording ends, and this recording is uploaded to the server and stored.
