[0037] Docking pick-up and delivery component embodiment:

[0038] See also Figure 1 and Figure 5 The docking and delivery assembly 10 provided in this embodiment includes a mounting base 1, a conveyor belt 2, a conveyor belt drive device 3, a push plate 4, and a push plate drive assembly 5. For ease of explanation, in this embodiment, the conveying direction of the conveyor belt 2 is defined as the Y direction, the direction perpendicular to the conveying direction is defined as the X direction, and the vertical direction is defined as the Z direction. Unless otherwise specified, the first direction in this embodiment is defined as the X direction, the second direction is defined as the Y direction, and the third direction is defined as the Z direction.

[0039] The mounting base 1 includes a base 11 and a rear seat 12, with the rear seat 12 being fixedly connected to the rear side of the base 11. A conveyor belt 2 is disposed on the upper portion of the base 11, and a conveyor belt drive device 3 is disposed on the base 11. The conveyor belt drive device 3 can drive the conveyor belt 2 to move backward in a second direction, that is, the conveyor belt 2 moves backward in the Y direction, so that food entering the front end of the conveyor belt 2 can be transported to the rear end of the conveyor belt 2, ensuring that the food is placed intact and stably on the conveyor belt 2, and also facilitating the subsequent push plate 4 to push the food to move.

[0040] The push plate 4 is arranged above the conveyor belt 2 and extends along the Y direction. The push plate driving assembly 5 can drive the push plate 4 to move along the first direction, which is perpendicular to the conveying direction of the conveyor belt 2, that is, drive the push plate 4 to move along the X direction to push the food away from the conveyor belt 2.

[0041] See also Figures 6 to 9 , and combined with Figure 1 The push plate driving assembly 5 is arranged on the rear seat 12 , and the push plate driving assembly 5 includes a first transmission assembly 51 , a first guide rail 52 , a first rack 53 , a gear 54 and a second transmission assembly 55 .

The docking and picking-up component 10 can move back and forth between the storage aisle 202 and the delivery channel 201, and is used to take away the food in the storage aisle 202 and move it to the supply cabinet through the cargo channel 201.

[0063] The storage cabinet 20 is equipped with a barrier seat 205, a driving wheel 203, a pusher transmission assembly 204, and a pusher plate (not shown) corresponding to each storage aisle 202. The barrier seat 205 is positioned on one side of the storage aisle 202 in its direction of extension and forms a sidewall of the storage aisle 202. The driving wheel 203 is positioned at one end of the barrier seat 205 near the entrance and exit of the storage aisle 202. The pusher transmission assembly 204 is positioned within the barrier seat 205 and is connected to the pusher plate and the driving wheel 203, respectively. The pusher plate is movably positioned within the storage aisle 202, extending perpendicularly to the width of the storage aisle 202.
