Description

Technical Field

[0001] The present application relates to the field of unmanned vending technology, and in particular to an unmanned vending machine. Background Art

[0002] Current unmanned vending machines, especially those that offer lunch boxes, require users to wait on-site for the meal to be heated before picking it up. During peak meal times, users can wait for a long time, which not only wastes a significant amount of time but also reduces the user experience with the unmanned vending machine. To address this issue, many manufacturers have begun researching meal storage solutions. For example, users can remotely reserve a lunch box, which, after automatically heating, is automatically moved by a robotic arm to a storage cabinet for temporary storage. Upon arrival, users can simply scan the QR code in the storage cabinet to pick up their meal, allowing them to pick it up anytime, without having to wait in line.

[0003] The above-mentioned meal storage plan is specifically as follows: a grid cabinet is placed next to the unmanned lunch box vending machine. A set of robotic arms, many independent grids and corresponding small doors are set on the grid cabinet. Each grid can accommodate at least one lunch box. After the lunch box is heated in the vending machine, the robotic arm in the grid cabinet will move the heated lunch box to the grid cabinet for storage, and the lunch box order number information in each grid will be recorded in the control system. When the user picks up the meal, the meal collection system is triggered by scanning the code or entering the order number. At this time, the corresponding grid door will be opened, and the small door will be closed after the user takes it away.

[0004] However, the above-mentioned food storage solution still has the following problems, including: the lattice cabinet can only be used to place and take out food on the front and sides where people can access it, and the space in the depth direction cannot be used for storage, resulting in too low space utilization; and the lattice cabinet has many small doors, each of which requires a lock, making the overall cost too high.

[0049] The meal storage solution for existing unmanned lunch box vending machines includes placing a grid cabinet next to it, which is equipped with a set of robotic arms, many independent grids and corresponding small doors. Each grid can accommodate at least one lunch box. After the lunch box is heated in the vending machine, the robotic arm in the grid cabinet will move the heated lunch box to the grid cabinet for storage, and the lunch box order number information in each grid will be recorded in the control system. When the user picks up the meal, the meal collection system is triggered by scanning the code or entering the order number. At this time, the corresponding grid door will be opened, and the small door will be closed after the user takes it away.

[0050] However, the above-mentioned unmanned lunch box vending machines still have the following problems: first, the grid cabinet can only be used to place and take out food on the front and sides where people can access it, and the space in the depth direction cannot be used to store food, resulting in low space utilization; second, the hot lunch boxes are transported by a robotic arm, that is, the lunch boxes are transported between the cooking cabinet and the storage cabinet by a robotic arm. This robotic arm is too complex and has low reliability, and is prone to damage and difficult to replace; third, the grid cabinet has many small doors, and each small door must be equipped with a lock, and the overall cost is too high; fourth, the robotic arm of the existing technology has up, down, left and right movements for transportation, which takes a long time to transport. The heated lunch box is soft, and this transportation method can easily cause the lunch box to fall; fifth, the grid cabinet door of the existing technology needs to be manually closed by people (similar to the cabinet door of the supermarket locker). If it is not closed, it will cause waste of grids and reduce the utilization efficiency.

[0051] In view of the above problems, the present invention provides an unmanned vending machine with a small footprint, simple structure and low cost. Figure 1 is a schematic diagram of the overall structure of an unmanned vending machine provided according to some embodiments of the present application; Figure 2 This is one of the cross-sectional structural diagrams of an unmanned vending machine provided according to some embodiments of the present application; Figure 3 This is a second schematic diagram of the cross-sectional structure of an unmanned vending machine provided according to some embodiments of the present application. Figure 1-Figure 3As shown, the unmanned vending machine 100 may include a vending machine 100, a cooking cabinet 200 and a food storage cabinet 300 arranged in sequence; wherein, the front panel of the food storage cabinet 300 is constructed with at least one food outlet 310; a transmission channel 210 is arranged between the cooking cabinet 200 and the food storage cabinet 300; a circulation mechanism 320 is arranged in the food storage cabinet 300, and a plurality of carriers 330 are arranged on the circulation mechanism 320. The circulation mechanism 320 can drive the plurality of carriers 330 to circulate in the food storage cabinet 300, and the circulation mechanism 320 is configured to move any one of the carriers 330 to the food outlet 310, or to move any one of the carriers 330 to the transmission channel 210 to receive the goods transmitted from the cooking cabinet 200.

[0052] It will be appreciated that in this example, the cooking cabinet 200 is placed between the vending cabinet 100 and the food storage cabinet 300, facilitating the direct delivery of goods (e.g., lunch boxes) from the vending cabinet 100 to the cooking cabinet 200, and also facilitating the direct delivery of heated lunch boxes from the cooking cabinet 200 to the food storage cabinet 300. To facilitate the transfer and transportation of goods between the cooking cabinet 200 and the food storage cabinet 300, a transfer channel 210 is formed between the cooking cabinet 200 and the food storage cabinet 300. To conserve space within the unmanned vending machine, the cooking cabinet 200 and the food storage cabinet 300 are typically positioned adjacent to each other. For example, the cooking cabinet 200 and the food storage cabinet 300 share a common panel, and the transfer channel 210 is a hole formed in this panel to facilitate the direct transfer of goods from the cooking cabinet 200 to the storage rack 330 within the food storage cabinet 300.

[0053] To save space within the food storage cabinet 300, goods can be transported from the cooking cabinet 200 to the loading rack 330 by designing the mobile tray 201 within the cooking cabinet 200 as a conveyor belt. This mobile tray 201 can not only receive goods transferred from the vending cabinet 100, but also move the goods within the cooking cabinet 200 for heating. The mobile tray 201 can move to the transmission channel 210 and then activate its own conveyor belt, allowing the goods placed on the conveyor belt to pass through the transmission channel 210 and move to the loading rack 330. It should be noted that to ensure that the goods on the mobile tray 201 can fall onto the loading rack 330 after passing through the transmission channel 210, both the mobile tray 201 and the loading rack 330 need to be located adjacent to the transmission channel 210, that is, they need to be located adjacent to the panel.

[0054] In addition to the above method, another way to move goods from the cooking cabinet 200 to the loading rack 330 is to set a pushing mechanism 110 on the side of the vending cabinet 100. When the goods are aligned with the transmission channel 210, the pushing mechanism 110 pushes the goods to the loading rack 330 on the other side of the transmission channel 210. The specific setting position and setting form of the pushing mechanism 110 can be understood by referring to the following example.

[0055] To increase the storage capacity of the food storage cabinet 300, a circulation mechanism 320 is provided within the food storage cabinet 300, and multiple racks 330 are connected to the circulation mechanism 320. If the user's food access direction is defined as forward, the circulation mechanism 320 drives the multiple racks 330 to move in a forward-downward-backward-upward-front or forward-upward-backward-downward-front manner. This method fully utilizes the space behind the food storage cabinet 300, allowing more racks 330 to be installed within the food storage cabinet 300 to carry goods.

[0056] In order to facilitate the transfer of goods to the rack 330 and the user to take the goods, the circulation mechanism 320 can drive the rack 330 to move in a manner that receives a signal for placing goods, drives any empty rack 330 among the multiple racks 330 to move to the transmission channel 210, and records the information of the goods corresponding to the rack 330; receives a signal for the user to take the goods, drives the rack 330 where the corresponding goods are located to move in a circular manner until the rack 330 moves to the food outlet 310 on the front panel of the food storage cabinet 300, and the goods can be pushed to the food outlet 310 by the built-in ejection rod, or the user can manually take the goods away. The specific method of taking the goods is not limited here.

[0057] Since the circulation mechanism 320 of this example can drive any one of the multiple carriers 330 to move to the food outlet 310, the number of food outlets 310 can be set to one or two according to the height of the user, thereby greatly reducing the number of food outlets 310 and corresponding opening and closing doors 311, making the structure simpler and reducing manufacturing costs. In one example, the front panel of the food storage cabinet 300 is movably connected to at least one opening and closing door 311, and the opening and closing door 311 is correspondingly provided to cover the food outlet 310. Specifically, the opening and closing door 311 can be electrically controlled and can slide (upward or downward) to open so as to expose the food outlet 310 and facilitate the user to take away the goods.

[0058] In the present application, by placing the food storage cabinet 300 on one side of the cooking cabinet 200 and forming a transmission channel 210 between the food storage cabinet 300 and the cooking cabinet 200, combined with a circulation mechanism 320 and multiple racks 330 provided within the food storage cabinet 300, it is convenient to transfer the goods processed in the cooking cabinet 200 to the racks 330 via the transmission channel 210, and the circulation mechanism 320 can move the goods to the depth of the food storage cabinet 300, thereby achieving the purpose of rationally utilizing the space within the food storage cabinet 300 and increasing the number of goods that can be placed. In addition, the circulation mechanism 320 can move the predetermined goods to the food outlet 310, eliminating the need to set up too many food outlets 310, simplifying the structure of the food outlet 310, reducing costs, and improving the user experience.

[0059] Below, we will combine the Figure 1 -Attached Figure 10 The structure of the unmanned vending machine provided in the embodiment of the present application is introduced in detail.

[0060] Figure 4 This is one of the position diagrams between the ejection mechanism 110, the movable tray 201 and the circulation mechanism 320 provided according to some embodiments of the present application; Figure 5 This is a second schematic diagram of the positions of the ejection mechanism 110, the moving tray 201 and the circulation mechanism 320 according to some embodiments of the present application. Figure 4 and Figure 5 As shown, in some embodiments, the adjacent panels of the vending cabinet 100 and the cooking cabinet 200 are constructed with openings, and the openings are arranged corresponding to the transmission channel 210; a pushing mechanism 110 is provided in the vending cabinet 100, and the end of the pushing mechanism 110 is used to extend from the opening and push the goods in the cooking cabinet 200 through the transmission channel 210 to the loading rack 330.

[0061] Specifically, the method for transferring goods from the vending cabinet 100 to the cooking cabinet 200 includes installing a conveyor belt in front of the freezer of the vending cabinet 100. When goods are transferred from the freezer to the conveyor belt, the conveyor belt is activated until the goods are moved into the cooking cabinet 200. The space above or below the conveyor belt can be reasonably utilized, for example, by installing a push-out mechanism 110. In one example, the push-out mechanism 110 is a telescopic rod.

[0062] The telescopic rod can be positioned above or below the conveyor belt. To push the goods from the cooking cabinet 200 onto the storage rack 330, an opening is constructed on the panel between the vending cabinet 100 and the cooking cabinet 200. This opening is compatible with the shape and size of the telescopic rod. To facilitate the telescopic rod in directly pushing the goods through the transmission channel 210 onto the storage rack 330, the opening can be positioned to correspond to the transmission channel 210. Specifically, the telescopic rod pushes the goods horizontally and is located on the same level as the transmission channel 210. When the goods reach this level, the telescopic rod is activated to push the goods into the transmission channel 210. Furthermore, the telescopic rod has a simple structure and low cost. It does not damage the heated lunch boxes, which are relatively soft. It also easily moves the soft lunch boxes, preventing them from falling off when the robotic arm grabs them.

[0063] like Figure 3 As shown, in some embodiments, the cooking cabinet 200 includes a processing area 220 and a transfer area 230. A heating device is provided in the processing area 220, and a mobile tray 201 is provided in the transfer area 230. The mobile tray 201 is configured to receive goods transferred from the vending machine 100 and move the goods to the processing area 220.

[0064] Specifically, to reduce the floor space of the cooking cabinet 200, the space within the cooking cabinet 200 must be rationally arranged. Consequently, the cooking cabinet 200 is divided into a processing area 220 and a transfer area 230. The heating device within the processing area 220 can be considered the upper half of an induction cooker, while the mobile tray 201 serves as the bottom plate of the induction cooker. The mobile tray 201 receives goods transferred from the vending machine 100. Therefore, during this process, the mobile tray 201 is positioned away from the processing area 220. Upon receiving the goods, it is moved to the processing area 220 for heating. The heated goods can be transferred directly to the carrier 330, or they can be transported by the mobile tray 201 to the transfer area 230 and then transferred to the carrier 330.

[0065] The moving mode of the mobile tray 201 can be as follows: Figure 4 and Figure 5 As shown, in some embodiments, a vertical guide rail is provided in the cooking cabinet 200, and the mobile tray 201 is connected to the vertical guide rail and can move up and down along the vertical guide rail. The mobile tray 201 is configured to connect the opening and the transmission channel 210 so that the ejection mechanism 110 pushes the goods on the mobile tray 201 to the loading rack 330.

[0066] Specifically, to reduce the footprint of the cooking cabinet 200, the mobile tray 201 can move along vertical guide rails, i.e., it can move up and down. Regardless of where the mobile tray 201 moves the processed goods (the processing area 220 or the transfer area 230), the mobile tray 201 can connect the opening and the transfer channel 210. That is, when the mobile tray 201 is located between the opening and the transfer channel 210, the telescopic rod can extend from the opening into the cooking cabinet 200 and push the goods on the mobile tray 201 toward the transfer channel 210 until they move to the carrier 330 on one side of the transfer channel 210.

[0067] like Figure 3 As shown, in some embodiments, the processing area 220 is located above the transfer area 230; the opening and the transfer channel 210 are formed in the transfer area 230; or, the opening and the transfer channel 210 are formed in the processing area 220.

[0068] Specifically, the processing area 220 is located above the transfer area 230. When goods need to be processed, the mobile pallet 201 drives the goods upward to the processing area 220. That is, at this time, the mobile pallet 201 and the processing area 220 form an induction cooker structure. When the opening and the transmission channel 210 are formed in the processing area 220, the mobile pallet 201 does not need to be moved after the goods are processed, and can be pushed onto the carrier 330 by the telescopic rod. Of course, in addition to the above method, the opening and the transmission channel 210 can also be set in the transfer area 230 to avoid affecting the processing quality and efficiency of the processing area 220. After the goods are processed, the mobile pallet 201 needs to drive the goods downward to the transmission channel 210, and then be pushed onto the carrier 330 by the telescopic rod.

[0069] In some embodiments, the panels at the opening and the transmission channel 210 are each provided with movable opening and closing covers to cover or open the opening and the transmission channel 210. Specifically, to prevent the opening and the transmission channel 210 from affecting the temperature between the vending cabinet 100, the cooking cabinet 200, and the food storage cabinet 300, the opening and closing covers between the three can be controlled to open during the transmission process, and can be controlled to close after the transmission is completed. To avoid affecting the internal space between the three, the opening and closing covers can be slidably provided on the panels, for example, they can be slid upward or downward to open. In particular, when the opening and the transmission channel 210 are formed in the processing area 220, to reduce the impact of the heating process of the heating device, opening and closing covers can be provided on opposite sides of the heating area to timely close the processing area 220 to facilitate the processing of goods.

[0070] In some embodiments, a constant temperature device is provided in the food storage cabinet 300 to keep the food storage cabinet 300 in a heat-insulating state.

[0071] Specifically, the constant temperature device is a heating element. Placing the heating element in the food storage cabinet 300 can ensure that the food storage cabinet 300 is in a heat-insulating state, thereby preventing the temperature of the processed goods from decreasing, which in turn affects the user's eating experience.

[0072] Figure 6 is a schematic diagram of the connection structure between the circulation mechanism 320 and the carrier 330 according to some embodiments of the present application; Figure 7 is a schematic diagram of the connection between the carrier 330 and the limiting plate 325 according to some embodiments of the present application; Figure 8 This is one of the schematic diagrams of the connection structure between the carrier 330 and the circulation mechanism 320 according to some embodiments of the present application; Figure 9 This is a second schematic diagram of the connection structure of the object carrier 330 and the circulation mechanism 320 provided according to some embodiments of the present application; Figure 10 3 is a schematic diagram of the structure of the object carrier 330 provided according to some embodiments of the present application. Figures 6-10As shown, in some embodiments, a support frame 340 is provided in the food storage cabinet 300, and a circulation mechanism 320 is provided on the support frame 340. The circulation mechanism 320 may include a drive motor 321, at least two sets of drive wheels 322, and at least two drive bars 323. The at least two sets of drive wheels 322 are connected to the output shaft of the drive motor 321; the at least two drive bars 323 are respectively wound around each set of drive wheels 322, and the drive bars 323 are connected to the carrier 330 via a connecting arm 331.

[0073] Specifically, the support frame 340 can effectively support the installation of the circulation mechanism 320. Drive wheels 322 and drive bars 323 wound around the drive wheels 322 can be provided on opposite sides of the support frame 340. The drive bars 323 are specifically drive chains, and the drive wheels 322 are specifically drive gears, with the drive chains wound around the drive gears. At least one of the drive wheels 322 can be connected to the output end of the drive motor 321, so that the drive motor 321 drives the drive wheel 322 to rotate, which in turn drives the drive bar 323 to rotate. The drive bar 323 drives the connecting arm 331 and the carrier 330 to move, thereby achieving the purpose of the circulation mechanism 320 driving the multiple carriers 330 to circulate within the locker.

[0074] like Figure 7-Figure 9 As shown, in some embodiments, the carrier rack 330 includes at least a bottom plate and side plates connected to both sides of the bottom plate, wherein one of the side plates is configured with a notch 3301, and the notch 3301 is used to correspond to the transmission channel 210; the outer wall of the side plate is installed with a connecting shaft 333, and the connecting shaft 333 is used to be rotatably connected to the connecting arm 331.

[0075] Specifically, the luggage rack 330 consists of a bottom plate, two side plates (left and right), an upper plate, and a rear plate. Because the front plate is used to deliver goods from the food outlet 310, there is no front plate. One of the side plates, which corresponds to the transport channel 210 to receive goods, is provided with a notch 3301. The notch 3301 is larger than the size of the goods, facilitating smooth loading of the goods onto the luggage rack 330. Connecting shafts 333 are mounted on the outer walls of both side plates. These are rotatably connected to connecting arms 331, which can drive the luggage rack 330 to move along with the drive bar 323.

[0076] However, in order to prevent the cargo from falling due to the shaking of the cargo carrier 330 during the rotation, in some embodiments, the circulation mechanism 320 further includes a limit plate 325, which is located between the drive bar 323 and the cargo carrier 330; the limit plate 325 is constructed with an annular channel 3251 and at least one annular guide rail 3252, the annular channel 3251 and the at least one annular guide rail 3252 being of the same size and staggered, and the annular channel 3251 is arranged to pass through the limit plate 325, and the connecting shaft 333 and / or the connecting arm 331 are arranged to pass through the annular channel 3251; the outer wall of the side plate opposite to the notch 3301 is provided with a plurality of guide wheels 332, which are distributed on the outer circumference of the connecting shaft 333, and are configured to be embedded in the annular guide rail 3252 to limit the shape of the cargo carrier 330 during the movement.

[0077] Specifically, since the side of the circulation mechanism 320 close to the cooking cabinet 200 needs to transport goods, a limit plate 325 is set on the side away from the cooking cabinet 200 and between the drive bar 323 and the cargo rack 330. The limit plate 325 is constructed with an annular channel 3251 passing through it. The annular channel 3251 is used for the connecting shaft 333 or the connecting arm 331, or part of the connecting shaft 333 and part of the connecting arm 331 to ensure the transmission of the driving bar 323, the connecting arm 331, the connecting shaft 333 and the cargo rack 330 on this side. An annular guide rail 3252 is also provided on the limiting plate 325. The annular guide rail 3252 does not need to be set through the limiting plate 325. The annular guide rail 3252 and the annular channel 3251 have the same shape and size, but different positions. That is, the annular guide rail 3252 and the annular channel 3251 need to be staggered, and the guidance of the annular guide rail 3252 needs to be adapted to the motion trajectory of at least one guide wheel 332 set on the outer wall of the side plate.

[0078] For example, four guide wheels 332 are evenly distributed on the outer wall of the side panel. When the side panel moves along the normal trajectory (when the luggage carrier 330 is not tilted) with the driving bar 323, the movement trajectory of the guide wheels 332 is the trajectory of the circular guide rails 3252. By embedding the guide wheels 332 in the corresponding circular guide rails 3252, the position of the luggage carrier 330 during movement can be effectively controlled, preventing the luggage carrier 330 from tilting and causing the cargo on it to slip.

[0079] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be encompassed by the claims of the present application.
