In the automatic delivery system for dishes provided by the present invention, by setting an installation platform, preferably the space above the installation platform includes the meal preparation area, and the space below the installation platform includes the dining area, and the upper and lower transport modules are installed on the installation platform, and then pass through the first A lifting device transfers items between the food preparation area and the dining area. On the one hand, it does not occupy the floor space, which avoids the use of automatic food delivery vehicles in the related art. , If the upstairs is the meal preparation area and the downstairs is the dining area, the dishes can be delivered upstairs and downstairs through the first lifting device, eliminating the need to manually transport the dishes from the upstairs to the downstairs, or transfer the remaining dishes from the downstairs. Wait for the delivery to the upstairs to save manpower.

Among them, the first lifting device can realize the transfer of items from the meal preparation area to the dining area, and also realize the transfer of items from the dining area to the meal preparation area, which is not only convenient for serving dishes, but also convenient for recycling the remaining plates and dishes. Conducive to the realization of automated serving and recycling, further saving manpower. Optionally, the first lifting devices are correspondingly distributed above the dining table in the dining area, so that the first lifting device can directly transport the dishes to the dining table or one side of the dining table, and can avoid manually transporting the remaining dishes to a farther lift. After the device is installed, the plate can be recycled to the meal preparation area, which provides great convenience for the user.

Of course, when the number of dining areas is multiple, there may also be a situation where the dining area is located on one side of the horizontal direction of the meal preparation area. In this case, the installation platform may include a partition to separate the left and right meal preparation areas. And the dining area, the upper and lower transport modules are arranged on the part of the installation platform corresponding to the dining area.

When the first object carrier 124 is located on one side of the transition plate 228 , it is convenient to pick up and place items on the first object carrier 124 from that side. When the first object carrier 124 is located in the limiting hole of the transition plate 228, at this time, the transition plate 228 surrounds the first object carrier 124, which can limit the first object carrier 124 and avoid the first carrier The object 124 is shaken, which causes the object to fall, which is beneficial to pick and place the object on the first object carrier 124 from multiple directions.

Further, when the first object carrier 124 of the first lifting device 12 is moved to the preset position, the upper surface of the transition plate 228 , the transport surface of the horizontal transport module, and the first object carrier 124 of the first lifting device 12 . The upper surfaces are all in the same plane.

In this embodiment, by disposing the transition plate 228 and directly or indirectly disposing the transition plate 228 on the support portion 222, and ensuring that the first object carrier 124 is in a preset position, the upper surface of the transition plate 228 It is in the same plane as the upper surface of the first object carrier 124, which is conducive to picking and placing items on the first object carrier 124 stably. The first object carrier 124 is stably pushed to the transition plate 228 so as to facilitate the stable transportation of items out of the first object carrier 124, which greatly improves the convenience and stability of picking and placing items on the first object carrier 124, and avoids the use of intelligent manipulators Taking the article directly from the first object carrier 124 results in the need to extend into the accommodating space 226 without interfering with the mounting plate 224 , resulting in complicated operation and increased R&D cost, which improves the stability of article transportation. Moreover, by setting the upper surface of the transition plate 228 and the transport surface of the horizontal transport module to be on the same plane, it is conducive to smooth transfer of articles between the horizontal transport module and the transition plate 228, and further improves the stability of article transport.

In some embodiments, the support frame 22 further includes: a limiting column, the limiting column is provided with through holes penetrating through both end surfaces, and the first object carrier 124 can be moved to a preset position through the through holes.

In this embodiment, by disposing a limiting column and opening through holes through the upper and lower end surfaces on the limiting column, the first object carrier 124 will move to a preset position through the through holes during the ascending process. The existence of the through hole can effectively limit the position of the first object carrier 124 and prevent the first object carrier 124 from shaking greatly, thereby facilitating the first object carrier 124 to pass through the through hole to stabilize before reaching the preset position. Then, it rises to the preset position to further improve the movement stability of the first object carrier 124 .

In some embodiments, when a limit hole is provided in the middle of the transition plate 228, the limit post is disposed on the lower surface of the transition plate 228, and the through hole communicates with the limit hole.

Below, the working process of the automatic food delivery system of an embodiment of the present invention is described in detail:

When it is detected that there is an item on the horizontal transportation module, the control device can be directly triggered to control the horizontal transportation module to move to a specific position along the first preset path, that is, beside the first lifting device 12, and then directly control the vegetable pushing device to move in a predetermined direction Push the dish, when it is detected that there is an item on the first lifting device 12, it is determined that the pushing of the dish is completed, and the control device is directly triggered to control the first lifting device 12 to descend to the dining area 100. At this time, it is convenient for the user to take the dish. When it is detected that the first lifting device 12 descends to the first preset position, and it is detected that there is no article on the first lifting device 12, the first lifting device 12 is controlled to rise to the second preset position , it is convenient to pass the dishes again. When it is detected that there is an item on the second lifting device 16, the control device can be directly triggered to control the second lifting device 16 to rise, or when the weight of the item on the second lifting device 16 reaches a preset value, the trigger can be directly triggered The control device controls the second lifting device 16 to rise to a certain height, controls the vegetable pushing device to push the items from the second lifting device 16 to the horizontal transport module, and then controls the horizontal transport module to transport the items to the recycling area. Automatic serving and recycling can be realized.
