[0001] The present invention relates to a robot restaurant system, and more specifically, to an unmanned restaurant system using a robot, by improving the means for supplying meal kit ingredients and plain rice for cooking and the means for supplying a tray for holding cooked food, so that the system can be operated efficiently. Background Technology

[0002] Recently, robot restaurant systems based on IT and robots are being developed to enable unmanned operation of restaurants or non-face-to-face operation with users, and some are being operated on a trial basis, although not in large numbers.

[0003] Although there is not much prior art related to the robot restaurant system described above, the technical details are as follows when examining the patent documents through the prior application of the present invention.

[0004] Patent Document 1 comprises a server unit (110) configured to manage and control order data, cooking data, and member data, and

[0011] Patent Application No. 10 - 2022 - 0146822

[0012] doesn't exist. The problem to be solved

[0013] The prior art described above relates to the overall configuration and control relationships of a robotic restaurant system, and focuses on enabling a series of operations, including ordering and payment for various types of convenience food menus, cooking, and serving to customers, to be performed non-face-to-face.

[0014] Since these prior art technologies lack specific technical details regarding what food to provide and how to store and retrieve the food to be cooked, and are based on the premise that food can be cooked and supplied to users, there are significant difficulties in actually operating them commercially.

[0015] In the conventional method, since the operator places food to be cooked in cooking containers, such as pots, and simply stacks them before moving them to the cooking counter by a robot, the stacked containers often collapse during the robot's handling process. This not only requires a significant amount of time to clean up the mess but also makes it difficult to continuously maintain a clean state.

[0016] Due to these issues, the operator has to help with surrounding tasks and, instead of stacking cooking containers in multiple layers, places them on the table in a single layer and refills them when they run out. This increases the operator's workload, leading to a problem where the purpose of operating unmanned or robotically becomes unclear.

[0017] Furthermore, in the case of plain rice served with cooked food, there is an inefficient aspect because, as mentioned earlier, operators place the required amount on specific tables due to the difficulty for robots to retrieve it from a simple thermos.

[0018] Furthermore, the current situation makes efficient and hygienic control and management difficult due to various inconveniences, such as the high risk of spoilage caused by the lack of refrigeration and heat retention for cooked food and plain rice, as well as increasing dissatisfaction among users due to cold rice. means of solving the problem

[0019] Accordingly, the present invention is designed to solve the above-mentioned problems and comprises: a kiosk (102) for ordering; a cooking space (104) on one side of a conveyor belt (103) installed in a long length; a consumption space (107) installed on the other side of the cooking space (104) so ​​that a user can consume food; a water purification unit (108) installed in the cooking space (104) to supply water to food to be cooked; and a cooking table (109) for heating food;

[0020] The apparatus comprises a meal kit supply means (120) installed to store a cooking container (110) containing cooked food, a rice supply means (140) installed to receive and discharge rice (111) on the side of the meal kit supply means (120), a robot (115) for moving the cooking container (110) and the rice (111), a tray supply means (160) installed at the starting position of a conveyor (103) to supply a tray (116) for carrying food and moving it, and a tray discharge means (180) installed at the position of the consumption space (107) to discharge the tray (116) to each seat where a user is located.

[0021] It is possible to achieve the goal of enabling store management close to unmanned operation with minimal effort by the manager to prepare food necessary for sale and to manage only the level of washing containers used for consumption and disposal. Effects of the invention

[0022] The present invention has the effect of enabling efficient operation and hygienic management by storing a cooking container containing meal kit-type cooked food so that a robot can easily pull it out and move it to a cooking counter, while also enabling refrigerated storage so that the cooked food inside the container does not spoil.

[0023] The present invention has the effect of increasing user convenience and reducing the workload of operators by providing rice that is always warm, by keeping the rice served with cooked food warm and discharging it along with cooking so that a robot can supply it to a serving tray.

[0024] The present invention has various effects, such as enabling a step forward in fully unmanned operation by mechanically performing the discharge of a tray capable of holding and serving cooked food and supplying the tray containing the food to the user. Brief explanation of the drawing

[0036] It is obvious that the above storage stand (130) is configured to have a multi-tiered tray (135) and a container jig (136) mounted on each layer to stably maintain the cooking container (110), and to allow the paper jig (132) to stop at the outlet (122) position by means of a sensor, etc.

[0037] The above-mentioned air rice supply means (140) is provided with an air rice supply body (141) in the shape of a cuboid on the upper part of a frame (141) provided in a grid shape, and an opening / closing door (142) is installed in front of the air rice supply body (141) while maintaining airtightness.

[0038] A plurality of rice magazines (143) are installed in the longitudinal direction inside the above-mentioned rice supply body (141) so that the rice (111) can be stacked in multiple layers, and the rice magazines (143) are configured to wrap about 2 / 3 of the rice (111), and the front part of the rice (111) is blocked by an opening / closing door (142).

[0039] A heat source (144), such as a heater, is installed at the rear of the above-mentioned rice magazine (143) to keep the rice (111) warm, and a plurality of ventilation holes (145) are formed in the rice magazine (143) so that the heat source of the heat source (144) can be transferred to the rice (111).

[0040] A discharge hole (146) is formed at the same location as the rice magazine (143) at the bottom of the above-mentioned opening / closing door (142), and a withdrawal tray (147) is extended so as to protrude forward from the discharge hole (146) so that the discharged rice (111) is completely exposed to the outside and there is no hindrance to the robot (115) picking it up.

[0041] A discharge cylinder (150) is installed at the rear of each of the above-mentioned rice magazines (143), and a discharge tip (151) is fixed to the loader tip of the discharge cylinder (150) so that the rice (111) located at the very bottom can be pushed and discharged.

[0042] It is obvious that the above-mentioned rice supply body (141) should be finished with an insulating material to prevent heat loss and not be exposed, and the quantity of rice (111) contained in each rice magazine (143) can be determined through a sensor, or a viewing window can be installed in the longitudinal direction on the opening / closing door (142) at the location of each rice magazine (143) to allow visual verification.

[0043] The above tray supply means (160) is composed of a lift (161) installed on the lower side of the conveyor (103) to raise the trays (116) stacked on the conveyor (103), and clampers (162) installed on both upper sides of the conveyor (103) to temporarily hold the trays (116) raised by the lift (161), excluding the lowest tray, so that they do not descend.

[0044] The above lift (161) has a lift frame (164) installed horizontally on the bottom surface of a sliding plate (163) located between the chains of a conveyor (103), and a lift cylinder (165) installed in the center of the lift frame (164).

[0045] A lift plate (167) is fixed to the rod (166) of the lift cylinder (165), and a lift guide (168) is installed around the lift cylinder (165) to raise and lower the lift plate (167) together with the lift cylinder (165).

[0046] At the location where the tray (116) is stacked, a tray tray (169) is installed on the front and both sides of the conveyor (103) to stably stack and maintain the tray (116).

[0047] The clamper (162) is configured such that a clamping cylinder (170) is mounted on both sides of the frame of the conveyor (103), and a clamping finger (173) is mounted on the rod (171) of the clamping cylinder (170) to lift the edges of the trays (116) raised by the lift (161), excluding the lowest tray, so as not to fall.

[0048] The above tray discharge means (180) secures a discharge space (181) on a sliding plate (163) located between the chains of a conveyor (103) at the table (105) of the intake space (107).

[0049] A lifting means (185) consisting of a lifting cylinder (183) and a guide rod (184) is installed on the discharge frame (182) installed on the bottom surface of the discharge space (181), and a discharge unit (190) is installed on the lifting means (185) to discharge the supplied tray (116) to the left or right table (105) of the transfer conveyor (103).

[0050] The above discharge unit (190) forms a unit frame (194) by connecting the lower plate (191) and the upper plate (192) with a vertical bar (193) to maintain a predetermined spacing, and the bottom surface of the lower plate (191) is connected to a lifting cylinder (183) and a guide rod (184).

[0051] A forward / reverse motor (195) is installed in the center of the unit frame (194), and a right discharge shaft (196) and a left discharge shaft (197) are installed in the right and left directions of the transfer conveyor (103), and a chain gear (198) is installed at both ends of the right and left discharge shafts (196, 197) and connected by a chain (200).

[0052] A driving bevel gear (201) is mounted on the output shaft of the above forward / reverse motor (195) to mesh with a driving bevel gear (202) mounted on either the right or left discharge shaft (196, 197), so that the transported tray (116) can be discharged to the right or left table (105).

[0053] The upper surface of the frame of the conveyor (103) is configured with a guide roller (205) to help discharge more than 2 / 3 of the discharged tray (116) onto the table (105).

[0054] The usage state of the robot restaurant system (100) to which the technology of the present invention as described above is applied is as follows.

[0055] The preparation is completed when the manager places the cooked food in the cooking container (110) and supplies it to the meal kit supply means (120), and the plain rice (111) is supplied to the plain rice supply means (140).

[0056] In this state, when a user places an order through the kiosk (102), the control unit retrieves the cooking container (110) from the meal kit supply means (120) via the robot (115), moves it to the water purification unit (108) to receive water, and then moves it to the cooking unit (109) to heat it so that cooking is performed.

[0057] During the cooking process, the tray supply means (160) transports the tray to the side of the cooking table (109), and the robot (115) places the rice (111) that is received and withdrawn from the rice supply means (140) onto the tray (116). When cooking is completed while this operation is being performed, the robot (115) places the cooking container (110) onto the tray (116).

[0058] Then, when the tray (116) is transported by the conveyor (103) to the table (105) where the ordering user is seated and stops, the tray discharge means (180) is operated so that the tray (116) containing the rice (111) and cooking container (110) is discharged to the table (105) where the user is seated.

[0059] After the user consumes the food, the tray (116) is placed on the dish disposal unit (300), and the manager collects it, washes it, and repeats the process of preparing it again.

[0060] When looking at the operation of the above meal kit supply means (120), the manager supplies a cooking container (110) containing food to be cooked to a storage stand (130) through the supply port (123) and places it in a standby state by pressing the cooking container (110) against a container jig (136) provided on each tray (135) constituting the supply stand (130).

[0061] When the robot (115) wants to retrieve the cooking container (110) while it is stored in this manner, the robot (115)’s arm approaches the extraction port (122) and opens it, and when the robot moves to the required position and retrieves the cooking container (110), the extraction port (122) closes again.

[0062] A cooler (126) is installed on the upper part of the meal kit supply body (121) to evenly spread cold air throughout, thereby maintaining the cooking container (110) containing the meal kit food at a constant temperature to prevent spoilage, and an insulating material (124) is interposed on the wall of the meal kit supply body (121) to maintain an even more uniform temperature.

[0063] The tray (135) constituting the storage rack (130) is configured to rotate by mounting a pinion gear (131) connected to the drive gear (133) of the drive motor (132) on the bottom surface, thereby ensuring that the cooking container (110) is always positioned at the outlet (122), which helps the robot (115) to easily extract it.

[0064] The operation of the above-mentioned rice supply means (140) involves opening the opening / closing door (142) provided at the front of the rice supply body (141), sequentially stacking the rice (111) into the rice magazine (143), and then closing the opening / closing door (142).

[0065] Then, the heat source (144) installed inside operates to maintain a constant temperature so that the rice (111) does not cool down, and the heat from the heat source (144) is transferred through the ventilation holes (145) formed in the rice magazine (143) to perform the heat retention operation.

[0066] When a signal for the extraction of the rice (111) is received, the extraction cylinder (150) installed at the rear lower side of the rice magazine (143) operates, and the extraction chip (151) pushes the rice (111) at the lowest side through the discharge hole (146) and positions it in the extraction tray (147), so that the robot (115) clamps and moves it.

[0067] Since the above-mentioned rice magazines (1432) are provided in multiple numbers, they operate sequentially so that when the rice in one rice magazine (143) is depleted, the rice magazine (143) at the next position operates to discharge the rice (111).

[0068] The operation of the above tray supply means (160) is such that first, the lift (161) operates to raise the entire tray (116) stacked on the tray tray (169), and the clamper (162) operates to lift and hold the upper trays, excluding the tray located at the bottom.

[0069] Then, the lift (161) is lowered again to place the tray located at the lowest position onto the conveyor (103), and at the same time, the conveyor (103) is operated to supply the tray to the side of the cooking table (109), and then the lift (161) is raised again and the clamp (162) is released to lower the entire tray.

[0070] The operation of the above lift (161) is such that a lift cylinder (165) is installed on a lift frame (164) installed below the transfer cup (103), connecting to a lift plate (167) on which a tray (116) is placed, and an auxiliary lift guide (168) also assists in safe raising and lowering.

[0071] The operation of the clamper (162) is such that a clamping cylinder (170) is mounted on both sides of the frame of the conveyor (103), and a clamping finger (173) is connected to the rod (171) of the clamping cylinder (170) to separate the trays other than the tray located at the bottom among the trays raised by the lift (161).

[0072] The operation of the above tray discharge means (180) is such that when a tray (116) containing a cooking container (110) and rice (111) is supplied to a user's location via a conveyor belt (103), the tray discharge means (180) located at that location operates to discharge the tray (116) to the user's location.

[0073] When the tray (116) arrives, a lifting means (185) consisting of a lifting cylinder (183) and a guide rod (184) installed on a discharge frame (182) installed below the discharge space (181) operates to raise the discharge unit (190) on which the tray is placed on the upper surface.

[0074] The height of the discharge unit (190) is higher than that of the conveyor (103), so that it rises to the same height as the table (105) on which the user is seated, and at the same time, the forward / reverse motor (195) installed on the unit frame (194) operates to operate in the forward or reverse direction depending on the user's position.

[0075] The operation of the above-mentioned forward / reverse motor (195) causes the driving bevel gear (201) to operate, thereby operating the driving bevel gear (202) mounted on the right or left discharge shaft (196, 197) to rotate the right or left discharge side (196, 197) in forward or reverse direction.

[0076] Then, the chain (200) connecting the chain gears (198) mounted on both ends of the right and left discharge shafts (196, 197) rotates to discharge the tray (116) to the table (105) at the required position, and in this process, the guide roller (205) installed on the upper part of the frame of the conveyor (103) helps to safely discharge the tray (116) to the table (105).

[0077] The present invention, as described above, has the advantage of allowing a manager to prepare food necessary for sale without exerting much effort, and enabling store management close to unmanned operation with only the level of management of washing containers used for consumption and disposal.
