[0047] 5. Dinner bowl. Detailed Implementation

[0048] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0049] This technical solution provides a food tray conveying device for a robotic smart restaurant, including a cover 1, a food tray lowering mechanism 2, a horizontal conveying mechanism 3, and a food tray lifting mechanism 4. The food tray lowering mechanism 2, the horizontal conveying mechanism 3, and the food tray lifting mechanism 4 are sequentially connected end to end inside the cover 1, and the top of the cover 1 is provided with an opening 101, which is used to avoid the upper end of the food tray lowering mechanism 2 and the lower end of the food tray lifting mechanism 4. The side wall of the cover 1 is provided with a tableware recycling window 102, and the tableware recycling window 102 is located in the same position as the horizontal conveying mechanism 3.

[0050] The structure of the bowl lowering mechanism 2 and the bowl lifting mechanism 4 is the same;

[0051] Both the bowl lowering mechanism 2 and the bowl lifting mechanism 4 include two conveying components 21 arranged opposite each other in the vertical direction, and a conveying gap is left between the two conveying components 21. The upper bowl end of the horizontal conveying mechanism 3 is located at the lower part of the conveying gap of the bowl lowering mechanism 2, and the lower bowl end of the horizontal conveying mechanism 3 is located at the lower part of the conveying gap of the bowl lifting mechanism 4.

[0052] The conveying assembly 21 includes a conveyor frame 211, a conveyor belt 212, and pallets 213. The conveyor belt 212 is arranged around the conveyor frame 211 and rotates relative to the conveyor frame 211. Multiple pallets 213 are provided and are spaced apart on the outside of the conveyor belt 212. The pallets 213 rotate with the conveyor belt 212.

[0053] The inner conveying sections of the conveyor belts 212 of the two conveying components 21 have the same conveying direction and are synchronized. The trays 213 of the two conveying components 21 are used together to support the dinner bowl 5. The lower limit of the conveying range of the conveying component 21 is located below the conveying surface of the horizontal conveying mechanism 3.

[0054] Currently, the common tableware recycling mode in smart restaurants is manual transportation. That is, the bowls full of tableware to be washed are manually collected from the tableware recycling area to the kitchen dishwashing room for cleaning. However, the manual transportation mode is very inefficient and it is difficult to collect tableware in a timely manner, thus affecting the dining experience of consumers in the dining area.

[0055] To achieve automated delivery of food bowls and improve the efficiency of tableware recycling, this technical solution proposes a food bowl delivery device for a robotic smart restaurant, which is used for tableware recycling. Specifically, as follows... Figure 1-8 As shown, the dinner bowl conveying device of this solution includes a cover 1, a dinner bowl lowering mechanism 2, a horizontal conveying mechanism 3, and a dinner bowl lifting mechanism 4. The top of the cover 1 is provided with an opening 101, which is used to avoid the upper end of the dinner bowl lowering mechanism 2 (i.e., the feeding end of the dinner bowl 5) and the lower end of the dinner bowl lifting mechanism 4 (i.e., the unloading end of the dinner bowl 5). The side wall of the cover 1 is provided with a tableware recycling window 102, which is located in the same position as the horizontal conveying mechanism 3.

[0056] The working process of the dinner bowl conveying device in this scheme is as follows: The empty dinner bowl 5 is conveyed to the dinner bowl lowering mechanism 2 by the cloud rail conveying device (such as cloud rail trolley), and the empty dinner bowl 5 is conveyed downward by the dinner bowl lowering mechanism 2 and loaded onto the upper end of the horizontal conveying mechanism 3; then, the empty dinner bowl 5 is used for tableware collection in the horizontal conveying mechanism 3 (that is, the consumer opens the tableware recycling window 102 and puts the tableware to be cleaned into the empty dinner bowl 5 at the top of the horizontal conveying mechanism 3 for collection); when the dinner bowl 5 is full of tableware, the horizontal conveying mechanism 3 continues to convey the full dinner bowl 5 to its lower end, and the dinner bowl lifting mechanism 4 conveys the full dinner bowl 5 upward, and finally the cloud rail conveying device moves it to the dishwashing room for tableware cleaning.

[0057] The dish tray conveying device in this solution can automatically transport dish trays 5. When dish tray 5 is full of tableware, it can be promptly transported away via the existing cloud rail conveyor. Simultaneously, empty dish trays 5 are quickly replenished to accommodate tableware, preventing tableware with food residue from accumulating in the dining area for extended periods and negatively impacting the dining experience. Furthermore, the combination of this dish tray conveying device and the existing cloud rail conveyor can completely replace manual transport, significantly reducing labor costs and improving the operational efficiency of the smart restaurant. In addition, the dish tray lowering mechanism 2, the horizontal conveying mechanism 3, and the dish tray lifting mechanism 4 are all installed inside the machine cover 1, effectively isolating odors. The tableware recycling window 102 within the machine cover 1 further helps to isolate odors, thereby enhancing the dining experience for consumers.

[0058] Furthermore, both the bowl lowering mechanism 2 and the bowl lifting mechanism 4 of this solution include two vertically oriented opposite conveying components 21, with a conveying gap between them to allow the bowl 5 to descend and rise within the conveying gap. Specifically, the conveying component 21 of this solution includes a conveyor frame 211, a conveyor belt 212, and a pallet 213, and the pallet 213 for supporting the bowl 5 rotates along with the rotation of the conveyor belt 212. When the inner conveying sections of the conveyor belts 212 of the two conveying components 21 in the bowl lowering mechanism 2 are simultaneously conveyed downwards, the bowl 5 can descend within the conveying gap when placed on the pallet 213 of the two conveying components 21; when the inner conveying sections of the conveyor belts 212 of the two conveying components 21 in the bowl lifting mechanism 4 are simultaneously conveyed upwards, the bowl 5 can rise within the conveying gap when placed on the pallet 213 of the two conveying components 21.

[0059] The dinner bowl lowering mechanism 2 and the dinner bowl lifting mechanism 4 in this design have simple structures and reliable performance, and can stably lower and raise the dinner bowl 5 in the vertical direction. Furthermore, the identical structures of the dinner bowl lowering mechanism 2 and the dinner bowl lifting mechanism 4 help reduce the design cost of the dinner bowl conveying device while ensuring stable performance.

[0060] To further explain, the horizontal conveying mechanism 3 includes a feeding conveying roller 31, a multi-station conveying roller 32 and a recycling conveying roller 33 connected end to end in sequence, and the conveying surfaces of the feeding conveying roller 31, the multi-station conveying roller 32 and the recycling conveying roller 33 are flush with each other. The multi-station conveying roller 32 is used to simultaneously accommodate and convey multiple bowls 5.

[0061] The feeding conveyor roller 31 is located at the lower part of the conveying gap of the bowl lowering mechanism 2, and the recycling conveyor roller 33 is located at the lower part of the conveying gap of the bowl lifting mechanism 4.

[0062] Specifically, the horizontal conveying mechanism 3 of this scheme includes three independently operating horizontal conveying sections: a feeding conveying roller 31, a multi-station conveying roller 32, and a recovery conveying roller 33, which are connected end to end in sequence, and the conveying surfaces of the three horizontal conveying sections are flush with each other. Among them, the feeding conveying roller 31 serves as a transfer device for the bowl 5 from the bowl lowering mechanism 2 to the multi-station conveying roller 32, and the recovery conveying roller 33 serves as a transfer device for the bowl 5 from the multi-station conveying roller 32 to the bowl lifting mechanism 4. This helps to ensure the smooth transfer of the bowl 5 between the bowl lowering mechanism 2, the horizontal conveying mechanism 3, and the bowl lifting mechanism 4, while reducing the maintenance cost and difficulty of the horizontal conveying mechanism 3.

[0063] To further explain, the multi-station conveying roller 32 includes a conveying bracket 321 and a rotating roller 322. Multiple rotating rollers 322 are provided, and the multiple rotating rollers 322 are rotatably spaced inside the conveying bracket 321.

[0064] The horizontal conveying mechanism 3 also includes a weighing component 34, which is installed at the bottom of the multi-station conveying roller 32, and the weighing end 341 of the weighing component 34 can protrude and retract on the conveying surface of the multi-station conveying roller 32.

[0065] In a preferred embodiment of this technical solution, the horizontal conveying mechanism 3 is further provided with a weighing component 34 for weighing the bowl 5. During the tableware collection process, the weight of the bowl 5 located at the top of the multi-station conveying roller 32 is detected, which can quickly determine the fullness of the tableware in the bowl 5. Thus, the bowl 5 filled with tableware can be quickly conveyed to the unloading conveying roller 31 through the multi-station conveying roller 32, and then carried away from the bowl conveying device by the bowl lifting mechanism 4, so as to clean the tableware in a timely manner.

[0066] Specifically, the horizontal conveying mechanism 3 operates as follows: When an empty bowl 5 is conveyed to the top of the weighing component 34 by the bowl lowering mechanism 2, the weighing end 341 of the weighing component 34 protrudes beyond the conveying surface of the multi-station conveying roller 32, and the empty bowl 5 is pushed away from the multi-station conveying roller 32, awaiting the placement of tableware. When the bowl 5 is filled with tableware (i.e., the weight of the bowl 5 reaches the preset weight), the weighing end 341 of the weighing component 34 retracts to the conveying surface of the multi-station conveying roller 32, and the bowl 5 filled with tableware falls back to the top of the multi-station conveying roller 32, where it continues to be conveyed.

[0067] It should be noted that the weighing component 34 in this solution is a weighing meter.

[0068] Furthermore, the horizontal conveying mechanism 3 also includes a waste collection tray 35, which is disposed below the weighing component 34;

[0069] Multiple weighing components 34 and multiple waste collection trays 35 are provided, and each waste collection tray 35 is correspondingly located below a weighing component 34.

[0070] As a preferred embodiment of the above, the horizontal conveying mechanism 3 of this solution also includes a waste collection tray 35, which is used to collect food residues left on the tableware in the serving dish 5, so as to facilitate the cleaning of the smart restaurant.

[0071] Furthermore, the horizontal conveying mechanism 3 also includes an upper basin positioning sensor 36 and a lower basin positioning sensor 37. Both the upper basin positioning sensor 36 and the lower basin positioning sensor 37 are protruding from the top of the conveying bracket 321. The upper basin positioning sensor 36 is located near the unloading conveying roller 31, and the lower basin positioning sensor 37 is located near the recycling conveying roller 33.

[0072] As another preferred embodiment, the horizontal conveying mechanism 3 of this solution also includes an upper basin positioning sensor 36 and a lower basin positioning sensor 37 to detect the upper and lower basins of the bowl 5 on the multi-station conveying roller 32, so as to facilitate the smooth operation of the bowl 5 between the bowl lowering mechanism 2, the horizontal conveying mechanism 3 and the bowl lifting mechanism 4, and improve the automation level of the bowl conveying device.

[0073] It should be noted that both the upper pot positioning sensor 36 and the lower pot positioning sensor 37 in this solution can be photoelectric switches.

[0074] Furthermore, the conveying assembly 21 also includes a drive sprocket assembly 214 and a driven sprocket assembly 215. The drive sprocket assembly 214 is rotatably disposed at the end of the conveyor frame 211, and the driven sprocket assembly 215 is rotatably disposed at the top of the conveyor frame 211.

[0075] The conveyor belt 212 is a conveyor chain. The conveyor belt 212 is engaged with the outer side of the drive sprocket group 214 and the driven sprocket group 215. The rotation of the drive sprocket group 214 and the driven sprocket group 215 drives the rotation of the conveyor belt 212.

[0076] In another preferred embodiment of this technical solution, the transmission method of the conveying component 21 is preferably chain drive. On the one hand, since chain drive has no elastic slippage or slippage, it is beneficial to improve its transmission efficiency. On the other hand, it can transmit greater power and has strong overload capacity, thus effectively improving the support capacity of the conveying component 21 for the dinner bowl 5.

[0077] To further explain, the tray lowering mechanism 2 also includes a drive motor 22 and a synchronization component 23, both of which are located near the end of the conveyor frame 211;

[0078] The output end of the drive motor 22 is connected to one end of the drive sprocket group 214 of the conveying assembly 21, and the drive motor 22 is used to drive the rotation of the drive sprocket group 214.

[0079] The other end of the active sprocket set 214 is connected to the active sprocket set 214 of another conveying component 21 via the synchronization component 23. The drive motor 22 drives the active sprocket sets 214 of the two conveying components 21 to rotate simultaneously via the synchronization component 23.

[0080] Furthermore, the tray lowering mechanism 2 of this solution also includes a drive motor 22 and a synchronization component 23, which are connected end to end by the drive motor 22, the drive sprocket set 214 of one conveying component 21, the synchronization component 23 and the drive sprocket set 214 of the other conveying component 21, which helps to ensure the synchronous operation of the two conveying components 21.

[0081] It should be noted that the drive motor 22 of this solution can achieve forward and reverse rotation in opposite directions, so as to be suitable for both the bowl lowering mechanism 2 for lowering the bowl 5 and the bowl lifting mechanism 4 for raising the bowl 5.

[0082] To further explain, the synchronization component 23 includes a driving gear 231, a gear set 232, a driven gear 233, and a transmission chain 234;

[0083] The driving gear 231, the gear set 232, and the driven gear 233 are rotatably mounted sequentially on the same side of the end of the conveyor frame 211;

[0084] The drive gear 231 is connected to one end of the drive sprocket group 214 of the conveying assembly 21, and the drive gear 231 and the drive sprocket group 214 rotate synchronously.

[0085] The driven gear 233 is connected to one end of the drive sprocket group 214 of another conveying component 21, and the driven gear 233 rotates synchronously with the drive sprocket group 214;

[0086] The gear set 232 includes a first transmission gear 2321 and a second transmission gear 2322 coaxially arranged, and the diameter of the first transmission gear 2321 is larger than the diameter of the second transmission gear 2322; the first transmission gear 2321 meshes with the driving gear 231, and the second transmission gear 2322 is connected to the driven gear 233 through the transmission chain 234, and the rotation of the second transmission gear 2322 drives the driven gear 233 to rotate through the transmission chain 234.

[0087] Furthermore, the synchronization component 23 of this solution includes a driving gear 231, a gear set 232, a driven gear 233, and a transmission chain 234, which is simple in performance and reliable in transmission.

[0088] Specifically, when the conveying component 21 of this solution is running, the drive motor 22 is first turned on, causing the drive motor 22 to directly drive the rotation of the drive sprocket set 214 of one conveying component 21. Since the drive gear 231 and the aforementioned drive sprocket set 214 rotate synchronously, and the driven gear 233 rotates synchronously with the drive sprocket set 214 of another conveying component 21, when the drive gear 231 rotates, it can be transmitted to the driven gear 233 in sequence through the gear set 232 and the transmission chain 234, thereby causing the drive sprocket set 214 of the other conveying component 21 to rotate. Moreover, the rotation of the drive sprocket sets 214 of the two conveying components 21 is opposite, so that the conveying direction of the inner conveying section of the conveyor belt 212 of the two conveying components 21 is the same and synchronous.

[0089] To further explain, the pallet 213 includes a mounting plate 2131 and a support plate 2132; the mounting plate 2131 is mounted on the outside of the conveyor belt 212, the long side of the support plate 2132 is connected to the long side of the mounting plate 2131, and the mounting plate 2131 and the support plate 2132 are perpendicular to each other;

[0090] When the pallet 213 is located inside the conveying gap, the support plate 2132 is located at the bottom of the mounting plate 2131.

[0091] In addition, the pallet 213 of this solution includes a mounting plate 2131 and a support plate 2132. The mounting plate 2131 is used to connect with the conveyor belt 212, and the support plate 2132 is used to support the dinner bowl 5 so as to achieve stable transportation of the dinner bowl 5.

[0092] To further explain, the support plate 2132 has baffles 2133 protruding from both ends along its length, and the support plate 2132 and the baffles 2133 are integrally formed.

[0093] When the pallet 213 is located inside the conveying gap, the baffle 2133 tilts upward.

[0094] Furthermore, in the pallet 213 of this solution, the support plate 2132 is provided with baffles 2133 protruding from both ends along the length direction. The baffles 2133 can limit the position of the bowl 5 to prevent the bowl 5 from falling off the pallet 213 during transportation, thereby improving the safety of transportation.

[0095] Preferably, the tray lowering mechanism 2 further includes a positioning detector 24, and multiple positioning detectors 24 are provided, with the multiple positioning detectors 24 being installed at intervals along the vertical direction on the conveyor frame 211. This is beneficial to the controllability of the structure.
