Description

Technical Field

[0001] This utility model relates to restaurant food delivery systems, and in particular to an automatic food delivery system that combines interior facade and floor plan. Background Technology

[0002] In the catering industry, there are two main methods for indoor food delivery: manual delivery and delivery robots. Manual delivery suffers from high labor costs; unstable staffing, high turnover, and increased management costs due to frequent recruitment and training; delivery delays during peak hours due to large customer volumes; and the need to handle multiple tasks such as seating, order collection, and order fulfillment; fluctuating service quality due to individual mood and experience, leading to poor service attitude and high error rates, negatively impacting customer experience. Delivery robots require high-precision biomimetic design and multimodal sensor configuration, resulting in high maintenance costs due to high reliance on specialized teams for troubleshooting. Due to their biomimetic structure and complex movements, delivery robots consume significantly more power, with a single battery life of only 2-4 hours, requiring frequent charging or battery replacements, affecting operational continuity; limited operating space and their larger size make them prone to obstacle avoidance failures in restaurants, leading to delivery failures; during peak hours with high customer traffic, the complex path planning of robots, requiring real-time adjustments to gait and posture for obstacle avoidance, makes them more susceptible to obstruction and delays in delivery efficiency.

[0003] It should be noted that the information disclosed in the background section above is only for understanding the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] The main purpose of this utility model is to overcome the defects existing in the above-mentioned background technology and provide an automatic food delivery system that combines indoor facade and floor plan.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automated food delivery system combining interior facade and floor plan, comprising:

[0007] The facade delivery module is installed on the restaurant facade and is used to transport food in a vertical plane;

[0008] A planar transport module, which is installed on the restaurant floor, includes a transport channel and a transport trolley running in the transport channel, for transporting food in a horizontal plane and transporting the food to the table via the transport channel;

[0009] The path module forms the food delivery path, including the starting point, food placement point on the facade, connection point, delivery path, return path, and the common area between the passage and the dining table;

[0010] The scheduling system, connected to the facade transport module and the planar transport module, is used for overall control and task distribution to the facade transport module and the planar transport module.

[0011] in,

[0012] The facade delivery module includes a food delivery device;

[0013] The transport trolley of the planar transport module includes a lifting mechanism;

[0014] The facade transport module transports the food delivery device to the facade food placement point, and through the cooperation of the lifting mechanism and the food delivery device, transfers the food delivery device to the transport trolley of the planar transport module;

[0015] The delivery trolley uses the lifting mechanism to transport the food delivery device to the designated table.

[0016] Furthermore, the facade transport module includes:

[0017] The facade glass is opaque, back-coated glass.

[0018] A facade operating mechanism is located on the back of the facade glass;

[0019] The food delivery device is located in front of the facade glass.

[0020] Furthermore, the food delivery device includes:

[0021] The magnet is attracted to the magnet assembly of the inner food delivery device in the facade operating mechanism;

[0022] Structural component, connected to the magnet;

[0023] A food container, mounted on the structural component, is used to hold the food.

[0024] The magnet is connected to the magnet group of the inner food delivery device through magnetic attraction, so that the food delivery device moves with the facade running mechanism.

[0025] Furthermore, in the planar transport module:

[0026] The transport channel consists of glass panels and channel walls, forming the operating space for the vehicle.

[0027] Furthermore, the lifting mechanism of the transport trolley is equipped with a magnetic component, which interacts with the magnet of the food transport device to drive the food transport device to move.

[0028] Furthermore, the facade delivery module includes at least two independent facade operating mechanisms, each of which includes a multi-axis drive mechanism for driving the food delivery device to move along a predetermined trajectory to the facade food placement point.

[0029] Furthermore, the facade delivery module includes a first action group and a second action group, each with its own independent activity trajectory and waiting point.

[0030] Furthermore, both the first action group and the second action group include a multi-axis drive mechanism, which includes an X-axis motor and a Y-axis motor;

[0031] The inner food delivery device and the food transport device corresponding to the first action group and the second action group are attracted by a magnet group to drive the food transport device to move.

[0032] The first action group has an independent first activity trajectory and a first waiting point, and the second action group has an independent second activity trajectory and a second waiting point. When the first action group moves to the first waiting point, it triggers the first action group and the second action group to automatically return to their respective starting positions.

[0033] Furthermore, the delivery channel includes a main road and a branch road connecting the dining table, and the connection point is located at the intersection of the main road and the branch road; the planar delivery module includes a main road trolley and a branch road trolley, the main road trolley is used to run on the main road and transport the food delivery device to the connection point, and the branch road trolley is used to run on the branch road and transport the food delivery device from the connection point to the dining table.

[0034] Furthermore, it also includes a light indicator component, which is installed on the delivery trolley, food delivery device and / or table to indicate the food delivery status through changes in light.

[0035] This utility model has the following beneficial effects:

[0036] This invention's automated food delivery system combines vertical and horizontal transport modules to achieve continuous transportation of food in both vertical and horizontal spaces, expanding the delivery coverage area. The complete path formed by the path module and the overall control of the scheduling system ensure efficient flow of food along preset paths. The coordination between the lifting mechanism and the food transport device ensures a smooth handover, guaranteeing safe food transport and facilitating final delivery. The overall system reduces human intervention, improves delivery efficiency and stability, and optimizes restaurant operations and the customer dining experience. Therefore, this invention effectively reduces the drawbacks of manual transport while addressing the pain points of traditional robotic transport, allowing food to be delivered to customers' tables via the optimal path, at the fastest speed, and with a more experiential feel.

[0037] This system significantly reduces labor costs. The entire process, from food preparation to delivery to the customer's table, requires no human intervention, making it much simpler. Furthermore, robotic delivery avoids the impact on service quality caused by human emotional fluctuations and high error rates. The system's overall structure is simple, eliminating the need for high-precision bionic design and multimodal sensors required by ordinary delivery robots, and battery life is not a major concern. The enclosed passageway prevents contact with people, eliminating worries about collisions or delivery failures. Even during peak hours with high foot traffic, it avoids obstacle avoidance issues that could hinder delivery.

[0038] Furthermore, the system significantly improves overall operational efficiency through the collaborative operation of multiple AGVs in different areas. The AGVs operate in a relatively fixed environment, unaffected by changes in customers or the ground conditions, greatly reducing obstacle avoidance requirements. This eliminates the need for high-precision sensors and high-performance processors, reducing system complexity and cost while enabling miniaturization of the AGVs, simplifying their structure, reducing weight, lowering energy consumption, and extending their range. Simultaneously, the AGVs follow fixed paths to the tables, traveling along preset routes, and each vehicle possesses obstacle avoidance capabilities, ensuring operational safety. The system can also monitor the AGVs' operational status in real time, facilitating timely understanding of food delivery progress and optimizing the service process. Additionally, from a user experience perspective, since the AGVs are not visible, only the plates moving above the aisle, combined with lighting effects, creates a mysterious visual effect, making the system more attractive.

[0039] In the preferred design, the system features two sets of motion groups that can operate in parallel via independent trajectories, improving the efficiency of vertical delivery. A multi-axis drive mechanism, such as an X-axis motor and a Y-axis motor, precisely controls the movement trajectory of the food delivery device, ensuring stable food delivery. The inner food delivery device and the food transport device are connected by magnetic adsorption, ensuring reliable connection during movement and preventing food from falling off. The design of automatically returning to the starting point after the first motion group reaches the waiting point enables cyclical operation of the motion groups, reducing manual intervention, improving system continuity and automation, and thus enhancing overall delivery efficiency. Furthermore, the partitioning of main and branch roads and the collaborative operation of main road and branch road vehicles allows for precise regional scheduling of food delivery, reducing path intersections. The main road vehicle focuses on long-distance transport, while the branch road vehicles handle end-of-line delivery, this division of labor improves the overall efficiency of horizontal delivery and facilitates precise system control of each stage, optimizing the delivery process.

[0040] Other beneficial effects of the embodiments of this utility model will be further described below. Attached Figure Description

[0054] This design, through the combination of facade and planar transport modules, enables continuous transportation of food in both vertical and horizontal spaces, expanding the delivery coverage area.

[0057] like Figure 4 , Figure 5 As shown, in some embodiments, in the planar transport module: the transport channel is composed of a glass panel 21 and a channel wall 22, forming the operating space of the trolley. The transport trolley 25 includes a control board 17, a navigation magnetic strip 18, a motor 19, and a battery 20; wherein, the control board 17, as the core control component, coordinates the operation of the motor 19, the battery 20, and the navigation magnetic strip 18; the navigation magnetic strip 18 provides path guidance for the trolley's operation, and the control board 17 plans the driving path based on the information from the navigation magnetic strip 18; the motor 19 provides power for the trolley's operation, and its operating status is controlled by the control board 17; the battery 20 provides power support for the control board 17, the motor 19, and other components, ensuring the normal operation of the trolley.

[0058] In some embodiments, a magnetic component is installed on the lifting mechanism 16 of the transport trolley 25 to interact with the magnet 13 of the food transport device 3 to drive the food transport device 3 to move.

[0059] like Figure 2 , Figure 7 , Figure 8 As shown, in some embodiments, the facade delivery module includes at least two independent facade operating mechanisms 2. Each facade operating mechanism 2 includes a multi-axis drive mechanism for driving the food delivery device 3 to move along a predetermined trajectory to the facade food placement point (such as facade food placement point 29 in area D, facade food placement point 33 in area C, facade food placement point 34 in area B, facade food placement point 35 in area A, and facade placement point 42).

[0060] like Figure 2 , Figure 8As shown, in some embodiments, the facade delivery module includes a first action group 11 and a second action group 10, the first action group 11 and the second action group 10 having independent activity trajectories (such as the activity trajectory 40 of the first action group 11 and the activity trajectory 41 of the second action group 10) and waiting points (such as the waiting point 44 of the first action group and the waiting point 43 of the second action group).

[0061] like Figure 2 , Figure 8 As shown, in some embodiments, both the first action group 11 and the second action group 10 include a multi-axis drive mechanism, which includes an X-axis motor 4 and a Y-axis motor 5; the inner motion device 9 corresponding to the first action group 11 and the second action group 10 is attracted to the food delivery device 3 by a magnet group to drive the food delivery device 3 to move; the first action group 11 has an independent first activity trajectory 40 and a first waiting point 44, and the second action group 10 has an independent second activity trajectory 41 and a second waiting point 43; wherein, when the first action group 11 moves to the first waiting point 44, it triggers the first action group 11 and the second action group 10 to automatically return to their respective starting positions. This design allows two sets of motion groups to operate in parallel via independent trajectories, improving the efficiency of facade delivery. A multi-axis drive mechanism consisting of X-axis and Y-axis motors precisely controls the movement trajectory of the food delivery device, ensuring the stability of food delivery. The inner food delivery device and the food delivery device are connected by magnetic adsorption, ensuring reliable connection during movement and preventing food from falling off. The design that triggers both sets to automatically return to the starting point after the first motion group reaches the waiting point enables cyclical operation of the motion groups, reducing manual intervention, improving the continuity and automation of system operation, and ultimately enhancing overall food delivery efficiency.

[0062] like Figure 7As shown, in some embodiments, the transport channel includes a main road and branch roads connecting to the dining tables. The connection points (connection point 28 in area C, connection point 36 in area D, connection point 37 in area B, and connection point 38 in area A) are located at the intersection of the main road and the branch roads. The planar transport module includes a main road trolley and a branch road trolley. The main road trolley is used to run on the main road and transport the food transport device 3 to the connection points (such as connection point 28 in area C, connection point 36 in area D, connection point 37 in area B, and connection point 38 in area A). The branch road trolley is used to run on the branch roads and transport the food transport device 3 from the connection points (such as connection point 28 in area C, connection point 36 in area D, connection point 37 in area B, and connection point 38 in area A) to the dining table. This design, through the partitioning of main roads and branch roads and the cooperation between main road vehicles and branch road vehicles, enables precise regional scheduling of food delivery and reduces path intersection interference. The main road vehicles focus on long-distance transportation, while the branch road vehicles are responsible for last-mile delivery to the dining table. This division of labor and cooperation improves the overall efficiency of surface transportation and facilitates precise control of each link by the system, thus optimizing the food delivery process.

[0063] In some embodiments, the automated food delivery system also includes a light indicator component disposed on the delivery trolley 25, the food delivery device 3, and / or the table, for indicating the food delivery status through changes in light.

[0064] In some embodiments, the upper surface of the glass panel 21 of the conveying channel and the lower surface of the food delivery device 3 are both made of materials with a low coefficient of friction to reduce friction.

[0065] The following further describes specific embodiments of this utility model and its working method.

[0066] The restaurant's overall automated food delivery system includes a facade delivery module, a horizontal delivery module, a path module, and a scheduling system. The facade delivery module comprises facade glass 1, two sets of facade operating mechanisms 2, and a food delivery device 3. Facade glass 1 is opaque back-coated glass; the facade operating mechanism 2 is located on the back of the glass, and the food delivery device 3 is located in front of the glass. Figure 1 As shown. The facade operating mechanism includes an X-axis motor 4, a Y-axis motor 5, a linear slider 6, a lead screw 7, a linear guide rail 8, an inner food delivery device 9, a second action group 10, a first action group 11, and an aluminum frame 12, as shown. Figure 2 As shown. The food delivery device includes a magnet 13, a structural component 14, and a food delivery container 15, as shown. Figure 3 As shown. The planar transport module includes a transport channel, a transport trolley 25, and a food transport device (which transitions from the vertical transport stage to the planar transport stage). The transport trolley 25 includes a lifting mechanism 16, a control board 17, a navigation magnetic strip 18, a motor 19, and a battery 20, as shown. Figure 4 As shown. The transport channel is the space for the trolley to operate. The channel height is the same as the table height. The transport channel includes a glass panel 21 and a channel wall 22, as shown. Figure 5As shown. The food delivery device operates above the glass panel 21. The food container 15 contains the food 24, and a delivery trolley 25 is provided. Figure 6 As shown. The path module includes the starting point 27, the C-zone connection point 28, the D-zone facade food placement point 29, the delivery path 30, the return path 31, the C-zone facade food placement point 33, the B-zone facade food placement point 34, the A-zone facade food placement point 35, the D-zone connection point 36, the B-zone connection point 37, the A-zone connection point 38, and the passageway and common area for tables 39, as shown. Figure 7 As shown, both facade transportation and floor-level transportation are controlled and distributed among various subsystems by a unified scheduling system. For example... Figure 8 The diagram shows the facade operation mechanism, the movement trajectory 40 of the first action group 11, the movement trajectory 41 of the second action group 10, the glass panel 21, the facade placement point 42, the waiting point 43 of the second action group, and the waiting point 44 of the first action group. The specific operation is as follows:

[0067] Surface Delivery Process: After guests enter the restaurant and are seated, they place their orders. The kitchen receives the order information, prepares the food, and places it on the delivery device. Based on the table number, a task is assigned to the system. Once the task is assigned, the lifting mechanism of the trolley at the starting point will rise, carrying the delivery device and food to the corresponding branch connection point on the table. After the main route trolley reaches the connection point, the lifting mechanism lowers to place the delivery device at the connection point and returns to the main route to await subsequent tasks. After the main route trolley leaves the connection point, the branch route trolley will enter the connection point. Upon arrival, the lifting mechanism of the trolley rises to carry the delivery device to the guest's table (the table is the raised position on the branch route). After arriving at the table, the trolley lowers to place the food on the table, and the trolley returns to the waiting area. The guest picks up the food, and the delivery is complete.

[0068] There are two methods for facade delivery. The first method is as follows: After guests enter the restaurant and are seated, they order food. The kitchen receives the food information and prepares the food. After preparation, the food is placed on the facade delivery device. The system issues a task based on the table number. After the task is issued, the second action group moves according to its trajectory. When the facade starts moving, the flat trolley starts moving to the lower part of the corresponding facade placement point and waits. When the facade is delivered to the upper part of the facade placement point, the X-axis motor stops and the Y-axis motor moves downward, causing the facade delivery device to land above the flat delivery glass. The trolley lifting mechanism rises and takes the facade delivery device away and delivers it to the branch connection point. The second action group moves according to its trajectory to the waiting point of the second action group. When the trolley arrives at the pick-up point, the lifting mechanism lowers to place the facade food delivery device at the pick-up point location. It then returns to the main road via the return path to await subsequent tasks. After the trolley leaves the pick-up point on the main road, the branch road trolley will enter the pick-up point. Upon arrival at the pick-up point, the trolley's lifting mechanism rises to deliver the facade food delivery device to the guest's table (the table is the raised position on the branch road). After arriving at the table, the trolley lowers its lifting mechanism to place the food on the table. The trolley then returns to the waiting area, and the guest takes the food, completing the food delivery.

[0069] Secondly, the operation process of the facade is as follows: After guests enter the restaurant and are seated, they place their orders. The kitchen receives the food information and prepares the food. After preparation, the food is placed on the facade food delivery device. The system issues a task according to the table number. After the task is issued, the first action group moves according to the first action group's activity trajectory to deliver the food. When the facade starts to move, the flat trolley starts to move to the lower part of the facade placement point and waits. When the facade is delivered to the upper part of the facade placement point, the X-axis motor stops running, and the Y-axis motor moves downward to make the facade food delivery device land above the flat transport glass. The trolley lifting mechanism rises and takes the facade food delivery device away and delivers it to the branch connection point. The first action group moves to the first action group waiting point according to the first action group's activity trajectory. When the trolley arrives at the pick-up point, the lifting mechanism lowers to place the facade food delivery device at the pick-up point location. It then returns to the main road via the return path to await subsequent tasks. After the trolley leaves the pick-up point on the main road, the branch road trolley will enter the pick-up point. Upon arrival at the pick-up point, the trolley's lifting mechanism rises to deliver the facade food delivery device to the guest's table (the table is the raised position on the branch road). After arriving at the table, the trolley lowers its lifting mechanism to place the food on the table. The trolley then returns to the waiting area, and the guest takes the food, completing the food delivery.

[0070] When the first motion group (facade movement group) reaches its waiting point, the automatic return procedure for both the first and second motion groups will be triggered. The first motion group will return to its starting position, and the second motion group will return to its starting position. The facade transport can be repeated in this manner.

[0071] As a specific implementation of the aforementioned automated food delivery system, and considering the operational logic of the facade and horizontal transport modules, facade transport and horizontal transport can also be implemented according to the following technical details:

[0072] Facade Delivery: The inner food delivery device and the food transport device are equipped with magnets, which attract and fix the two structures together. When the facade running mechanism on the inner side of the glass moves, the magnets attract and drive the outer food transport device to move synchronously. Each facade running mechanism is equipped with two stepper motors, and the motor operating parameters are uniformly adjusted by the control board, thereby driving the food transport device to move precisely along a preset curved trajectory. At the same time, to reduce the frictional resistance between the food transport device and the facade glass, the food transport device is made of a low-friction coefficient and lightweight material, ensuring smooth and efficient movement.

[0073] Surface transport: The lifting mechanism of the transport trolley is equipped with magnetic components that interact with the magnetic components on the food transport device, attracting and moving the device to transport the food to the designated table. To reduce friction between the food transport device and the upper surface of the transport channel, the upper surface of the channel is made of glass, while the lower surface of the food transport device is made of a low-friction material. The magnetic components on the trolley have a lifting function; they rise to connect with the food transport device when picking up food and lower to detach from the device after reaching the table, completing the food placement.

[0074] In addition, the planar delivery system connects the tables in specific areas into a whole through channels, with each area assigned a branch line trolley responsible for delivering meals; the main line trolley on the main channel transports the prepared meals to the corresponding area's pick-up point, and then the branch line trolley of that area delivers the meals from the pick-up point to the designated table, realizing collaborative meal delivery by area.

[0075] Meanwhile, the delivery carts, food delivery devices, and tables are all equipped with lighting indicators that provide real-time feedback on the food's delivery status (e.g., in transit, arrived) through changes in light color or flashing patterns. A protective cover is also installed above the food delivery device to effectively prevent food contamination during transport. The system is equipped with software that can monitor the AGV's location, status, and battery level in real time. Delivery tasks can be issued via the user interface, and intelligent allocation of right-of-way and traffic control at intersections ensure order and safety during multi-vehicle collaborative operation.

[0076] In the planar transport module, the lifting mechanism of the transport trolley preferably uses neodymium iron boron strong magnets, and the magnets of the lifting mechanism and the food transport device correspond to form strong magnetic lines of force, thereby ensuring that the overall magnetism reaches the required magnetic attraction strength. The food transport device is provided with mounting holes for securely mounting protruding components that contact the glass surface. The protruding components are located on the side of the food transport device facing the glass surface, and can specifically be a micro-protrusion array structure. Each protrusion has a diameter of, for example, 5mm and an arc length of, for example, 1.25mm. Through the design of the curved surface of the protrusion contacting the glass, it forms a near-point contact with the glass surface, achieving a smooth and fluid operation. Multiple micro-protrusions can be configured on the contact surface between the food transport device and the glass, and these protrusions can be symmetrically distributed, for example, in a square. Through geometric center-of-gravity balance, the food transport device maintains a minimal contact area between the protrusions and the glass surface when moving in a straight line, a curve, or at any angle, ensuring the stability of the operation.

[0077] The automated food delivery system of this utility model has several advantages. The delivery method effectively reduces manual delivery costs. The entire process from food preparation to delivery to the customer's table requires no human intervention, making it simpler. Furthermore, machine delivery avoids the impact on service quality caused by human emotional fluctuations and high error rates. The overall system structure is simple, eliminating the need for high-precision bionic design and multimodal sensor configurations required for ordinary delivery robots, and also alleviating concerns about battery life. Simultaneously, the enclosed channel design prevents contact with people, eliminating worries about robot-human collisions and delivery failures. Even during peak hours with high foot traffic, it avoids delivery obstructions due to obstacle avoidance issues. In addition, the system significantly improves overall operational efficiency through the collaborative operation of multiple AGVs in designated areas. The relatively fixed operating environment of the AGVs is unaffected by changes in customers or the ground environment, greatly reducing obstacle avoidance requirements. The system eliminates the need for high-precision sensors and high-performance processors, which not only reduces system complexity and cost but also enables AGV miniaturization, simplified structure, weight reduction, energy consumption reduction, and extended battery life. Furthermore, the carts follow a relatively fixed path to the tables, traveling along preset routes, and each cart is equipped with obstacle avoidance capabilities to ensure operational safety. The system can also monitor the carts' operational status in real time, allowing for timely understanding of food delivery progress and thus optimizing the service process. Additionally, from a user experience perspective, since the carts are not visible, only the plates moving above the aisle, combined with lighting effects, it creates a mysterious visual effect, making it more attractive.

[0078] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various equivalent substitutions or obvious modifications can be made without departing from the concept of the present invention, and all such modifications, achieving the same performance or purpose, should be considered within the protection scope of the present invention.
