The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0049] The present technical solution provides a meal bowl conveying device for a robot smart restaurant, comprising a machine cover 1, a meal bowl lowering mechanism 2, a horizontal conveying mechanism 3 and a meal bowl lifting mechanism 4, wherein the meal bowl lowering mechanism 2, the horizontal conveying mechanism 3 and the meal bowl lifting mechanism 4 are sequentially installed end to end inside the machine cover 1, and an opening 101 is provided on the top of the machine cover 1, wherein the opening 101 is used to avoid the upper basin end of the meal bowl lowering mechanism 2 and the lower basin end of the meal bowl lifting mechanism 4; a tableware recovery window 102 is provided on the side wall of the machine cover 1, and the setting position of the tableware recovery window 102 is the same as the setting position of the horizontal conveying mechanism 3;

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

[0051] The bowl lowering mechanism 2 and the bowl lifting mechanism 4 each include two conveying assemblies 21 arranged opposite to each other in the vertical direction, and a conveying gap is left between the two conveying assemblies 21, and the upper basin 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 basin 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 conveyor assembly 21 includes a conveyor frame 211, a conveyor belt 212 and a support plate 213. The conveyor belt 212 is arranged around the conveyor frame 211 and rotates relative to the conveyor frame 211. A plurality of support plates 213 are provided. The plurality of support plates 213 are installed at intervals on the outside of the conveyor belt 212 and the support plates 213 rotate along with the rotation of the conveyor belt 212.

[0053] The conveying directions of the inner conveying sections of the conveyor belts 212 of the two conveying assemblies 21 are the same and synchronous, and the support plates 213 of the two conveying assemblies 21 are used together to support the dining basin 5; the lower limit of the conveying range of the conveying assembly 21 is located below the conveying surface of the horizontal conveying mechanism 3.

[0054] At present, 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 back kitchen dishwasher to wait for cleaning. However, the manual recycling transportation mode is very inefficient and it is difficult to recycle the tableware in a timely manner, thus affecting the dining experience of consumers in the dining area.

[0055] In order to realize the automatic conveyance of tableware and improve the efficiency of tableware recycling, this technical solution proposes a tableware conveying device for a robot smart restaurant, which is used for the recycling of tableware. Figure 1-8 As shown, the meal bowl conveying device of the present scheme includes a machine cover 1, a meal bowl lowering mechanism 2, a horizontal conveying mechanism 3 and a meal bowl lifting mechanism 4, and an opening 101 is provided on the top of the machine cover 1, which is used to avoid the upper basin end of the meal bowl lowering mechanism 2 (i.e., the loading end of the meal bowl 5) and the lower basin end of the meal bowl lifting mechanism 4 (i.e., the unloading end of the meal bowl 5); and a tableware recovery window 102 is provided on the side wall of the machine cover 1, and its setting position is the same as that of the horizontal conveying mechanism 3.

[0056] The working process of the meal bowl conveying device of the present scheme is as follows: the empty meal bowl 5 is conveyed to the meal bowl descending mechanism 2 by a cloud rail conveying device (such as a cloud rail trolley, etc.), and the empty meal bowl 5 is conveyed downward by the meal bowl descending mechanism 2 and loaded to the upper basin end of the horizontal conveying mechanism 3; then, the empty meal bowl 5 is used to collect tableware in the horizontal conveying mechanism 3 (that is, the consumer opens the tableware recovery window 102 and puts the tableware to be cleaned into the empty meal bowl 5 at the top of the horizontal conveying mechanism 3 for collection); when the meal bowl 5 is full of tableware, the horizontal conveying mechanism 3 conveys the meal bowl 5 full of tableware to its lower basin end, and the meal bowl 5 full of tableware is conveyed upward by the meal bowl lifting mechanism 4, and finally moved to the dishwashing room by the cloud rail conveying device for cleaning the tableware.

[0057] The meal bowl conveying device of the present solution can realize the automatic conveying of the meal bowl 5. When the meal bowl 5 is full of tableware, the meal bowl 5 full of tableware can be promptly transported away through the existing cloud rail conveying device, and at the same time, the empty meal bowl 5 can be quickly replenished to wait for the tableware to be put in, which is conducive to avoiding the tableware with food residues remaining on it from piling up in the dining area for a long time, affecting the dining experience of consumers. And the combination of the meal bowl conveying device of the present solution and the existing cloud rail conveying device can completely replace manual conveying, greatly reducing labor costs and improving the operating efficiency of smart restaurants. In addition, the meal bowl lowering mechanism 2, the horizontal conveying mechanism 3 and the meal bowl lifting mechanism 4 of the present solution are all installed inside the machine cover 1, which can effectively isolate odors; at the same time, the setting of the tableware recovery window 102 in the machine cover 1 is also conducive to further isolating odors, thereby improving the dining experience of consumers.

[0058] Furthermore, the meal bowl lowering mechanism 2 and the meal bowl lifting mechanism 4 of the present solution both include two conveying components 21 arranged opposite to each other in the vertical direction, and a conveying gap is left between the conveying components 21 to realize the lowering and rising of the meal bowl 5 in the conveying gap. Specifically, the conveying component 21 of the present solution includes a conveying frame 211, a conveyor belt 212 and a support plate 213, and the support plate 213 for supporting the meal bowl 5 rotates following the rotation of the conveyor belt 212. When the conveying direction of the inner conveying section of the conveyor belt 212 of the two conveyor components 21 in the meal bowl lowering mechanism 2 is synchronously downward, when the meal bowl 5 is placed on the support plates 213 of the two conveyor components 21, it can be lowered in the conveying gap in the meal bowl lowering mechanism 2; when the conveying direction of the inner conveying section of the conveyor belt 212 of the two conveyor components 21 in the meal bowl lifting mechanism 4 is synchronously upward, when the meal bowl 5 is placed on the support plates 213 of the two conveyor components 21, it can be raised in the conveying gap in the meal bowl lifting mechanism 4.

[0059] The bowl lowering mechanism 2 and the bowl lifting mechanism 4 of the present invention have simple structures and reliable performance, and can stably realize the vertical descent and ascent of the bowl 5. Moreover, the bowl lowering mechanism 2 and the bowl lifting mechanism 4 have the same structure, which is conducive to reducing the design cost of the bowl conveying device while ensuring stable performance.

[0060] Further, the horizontal conveying mechanism 3 includes a feed conveying roller 31, a multi-station conveying roller 32 and a recovery conveying roller 33 which are sequentially connected end to end, and the conveying surfaces of the feed conveying roller 31, the multi-station conveying roller 32 and the recovery conveying roller 33 are flush with each other, and the multi-station conveying roller 32 is used to simultaneously accommodate and convey multiple dining bowls 5;

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

[0062] Specifically, the horizontal conveying mechanism 3 of the present solution includes three independently operated horizontal conveying sections, namely, the unloading conveying roller 31, the multi-station conveying roller 32 and the 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 unloading conveying roller 31 serves as a transfer device for the dining bowl 5 from the dining bowl lowering mechanism 2 to the multi-station conveying roller 32, and the recovery conveying roller 33 serves as a transfer device for the dining bowl 5 from the multi-station conveying roller 32 to the dining bowl lifting mechanism 4, which is conducive to ensuring the smooth transfer of the dining bowl 5 between the dining bowl lowering mechanism 2, the horizontal conveying mechanism 3 and the dining bowl lifting mechanism 4, while reducing the maintenance cost and difficulty of the horizontal conveying mechanism 3.

[0063] Further, the multi-station conveying roller 32 includes a conveying bracket 321 and a rotating roller 322. The rotating roller 322 is provided with a plurality of rollers, and the plurality of rotating rollers 322 are rotatably arranged at intervals inside the conveying bracket 321.

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

[0065] In a preferred embodiment of the present technical solution, the horizontal conveying mechanism 3 is further provided with a weighing assembly 34 for weighing the tableware bowl 5. During the tableware collection process, the weight of the tableware bowl 5 located on the top of the multi-station conveying roller 32 is detected, and the fullness of the tableware in the tableware bowl 5 can be quickly known, so that the tableware bowl 5 filled with tableware can be quickly conveyed to the unloading conveying roller 31 through the multi-station conveying roller 32, and taken away from the tableware bowl conveying device by the tableware bowl lifting mechanism 4, so that the tableware can be cleaned in time.

[0066] Specifically, the working process of the horizontal conveying mechanism 3 in this solution is as follows: when the empty tableware 5 is conveyed to the top of the weighing assembly 34 by the tableware lowering mechanism 2, the weighing end 341 of the weighing assembly 34 is made to protrude from the conveying surface of the multi-station conveying roller 32, and the empty tableware 5 is pushed away from the multi-station conveying roller 32, waiting for the tableware to be put in. When the tableware 5 is filled with tableware (that is, the weight of the tableware 5 reaches the preset weight at this time), the weighing end 341 of the weighing assembly 34 is retracted to the conveying surface of the multi-station conveying roller 32, and the tableware 5 filled with tableware is dropped back to the top of the multi-station conveying roller 32, and the multi-station conveying roller 32 continues to convey it.

[0068] Further, the horizontal conveying mechanism 3 further includes a dirt receiving pan 35, and the dirt receiving pan 35 is arranged below the weighing assembly 34;

[0069] The weighing assembly 34 and the dirt receiving pan 35 are both provided in plurality, and one dirt receiving pan 35 is correspondingly provided below one weighing assembly 34 .

[0070] As a preferred embodiment of the above embodiment, the horizontal conveying mechanism 3 of the present solution also includes a dirt receiving tray 35, so as to receive the food residues left by the tableware in the dining bowl 5, so as to facilitate the cleaning of the smart restaurant.

[0071] Further, the horizontal conveying mechanism 3 also includes an upper basin in place sensor 36 and a lower basin in place sensor 37, and the upper basin in place sensor 36 and the lower basin in place sensor 37 are both protruding from the top of the conveying bracket 321, and the upper basin in place sensor 36 is arranged close to the unloading conveying roller 31, and the lower basin in place sensor 37 is arranged close to the recovery conveying roller 33.

[0072] As another preference of the above embodiment, the horizontal conveying mechanism 3 of the present scheme also includes an upper basin in place sensor 36 and a lower basin in place sensor 37 to detect the upper basin and the lower basin of the dining bowl 5 on the multi-station conveying roller 32, so as to facilitate the smooth operation of the dining bowl 5 between the dining bowl lowering mechanism 2, the horizontal conveying mechanism 3 and the dining bowl lifting mechanism 4, thereby improving the degree of automation of the dining bowl conveying device.

[0073] It should be noted that the upper basin in place sensor 36 and the lower basin in place sensor 37 of the present solution can both be photoelectric switches.

[0074] Further, the conveying assembly 21 further includes a driving sprocket group 214 and a driven sprocket group 215, wherein the driving sprocket group 214 is rotatably disposed at the end of the conveying frame 211, and the driven sprocket group 215 is rotatably disposed at the top of the conveying frame 211;

[0075] The conveyor belt 212 is a conveyor chain, and the conveyor belt 212 is meshed with the outer sides of the driving sprocket set 214 and the driven sprocket set 215 . The rotation of the driving sprocket set 214 and the driven sprocket set 215 drives the rotation of the conveyor belt 212 .

[0076] In another preferred embodiment of the present technical solution, the transmission mode of the conveying component 21 is preferably chain drive. On the one hand, since the chain drive has no elastic sliding and slipping phenomenon, it is beneficial to improve its transmission efficiency. On the other hand, it can transmit greater power and has a strong overload capacity, thereby effectively improving the conveying component 21's supporting capacity for the dining basin 5.

[0077] Further, the bowl lowering mechanism 2 further includes a driving machine 22 and a synchronization component 23, and the driving machine 22 and the synchronization component 23 are both arranged near the end of the conveying frame 211;

[0078] The output end of the driving machine 22 is connected to one end of a driving sprocket set 214 of the conveying assembly 21, and the driving machine 22 is used to drive the rotation of the driving sprocket set 214;

[0079] The other end of the driving sprocket set 214 is connected to the driving sprocket set 214 of another conveying assembly 21 through the synchronization assembly 23 , and the driving machine 22 drives the driving sprocket sets 214 of the two conveying assemblies 21 to rotate simultaneously through the synchronization assembly 23 .

[0080] Furthermore, the dinner bowl lowering mechanism 2 of the present scheme also includes a driving machine 22 and a synchronization component 23, and is connected end to end in sequence through the driving machine 22, the active sprocket group 214 of one conveying component 21, the synchronization component 23 and the active sprocket group 214 of another conveying component 21, which helps to ensure the synchronous operation of the two conveying components 21.

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

[0082] To further illustrate, the synchronization assembly 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 on the same side of the end of the conveying frame 211 in sequence;

[0084] The driving gear 231 is connected to one end of a driving sprocket set 214 of the conveying assembly 21, and the driving gear 231 and the driving sprocket set 214 rotate synchronously;

[0085] The driven gear 233 is connected to one end of the driving sprocket set 214 of the other conveying assembly 21, and the driven gear 233 rotates synchronously with the driving sprocket set 214;

[0086] The gear set 232 includes a first transmission gear 2321 and a second transmission gear 2322 which are 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 is meshed 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 structure of the synchronization component 23 of the present solution includes a driving gear 231, a gear set 232, a driven gear 233 and a transmission chain 234, and has simple performance and reliable transmission.

[0088] Specifically, when the conveying assembly 21 of the present scheme is in operation, the driving machine 22 is first turned on, so that the driving machine 22 directly drives the rotation of the driving sprocket group 214 of one conveying assembly 21; since the driving gear 231 and the above-mentioned driving sprocket group 214 rotate synchronously, the driven gear 233 rotates synchronously with the driving sprocket group 214 of the other conveying assembly 21. Therefore, when the driving gear 231 rotates, it can be transmitted to the driven gear 233 through the gear group 232 and the transmission chain 234 in sequence, thereby causing the driving sprocket group 214 of the other conveying assembly 21 to rotate, and the driving sprocket groups 214 of the two conveying assemblies 21 rotate in the opposite direction, so that the conveying directions of the inner conveying sections of the conveyor belts 212 of the two conveying assemblies 21 are the same and synchronous.

The technology, method and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0098] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0099] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0100] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0101] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0102] The technical principle of the present invention is described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanations herein, those skilled in the art can associate other specific implementations of the present invention without paying creative labor, and these methods will fall within the scope of protection of the present invention.
