The goods shelf 74 is fixedly arranged in the heat preservation cabinet body 71, the goods shelf 74 is provided with a plurality of goods channels for placing food, and 1 goods inlet 71-1 of the heat preservation cabinet body 71 is communicated with 1 goods channel of the goods shelf 74 and is arranged in a matching way. The number of the shelves 74 can be 1 or 2, preferably, in the embodiment, there are 2 shelves 74, 2 shelves 74 are oppositely arranged in the heat insulation cabinet 71 from left to right, and an empty space for installing the goods in and out device 76 is provided between the 2 shelves 74.

The lane tote 75 is used to transport meals from the lane to the tote 76 during use.

Referring to fig. 12, as a specific implementation manner, the cargo way discharging device 75 mainly comprises a mounting frame 75-1, a conveyor belt 75-2 disposed on the mounting frame 75-1, and a conveyor belt driving motor 75-3 disposed on the mounting frame 75-1 for driving the conveyor belt 75-2. The lane departure device 75 is provided with 1 set of its mounting bracket 75-1 in each lane of the shelf 74. In use, the conveyor belt 75-2 is driven by the conveyor belt driving motor 75-3 to move to push down the food placed thereon.

Referring to fig. 13, as another specific implementation manner, the cargo way delivery device 75 is composed of a support frame 75-4 and a three-axis movement mechanism disposed on the support frame 75-4. The three-axis movement mechanism consists of 2 sets of Z-axis lead screw motor components 75-5 which are arranged on a support frame 75-4 and can move up and down, a Y-axis lead screw motor component 75-6 which follows the 2 sets of Z-axis lead screw motor components 75-5 and can move up and down and back and forth, and an X-axis push screw motor component 75-7 which follows the Y-axis lead screw motor component 75-6 and can move left and right. Wherein the X-axis push bar motor assembly 75-7 comprises a push bar for pushing, in use, food on the lane of the shelf 74 to move to the in and out device 76, and a motor for driving the push bar to move. Preferably, the front end of the push rod of the X-axis push rod motor assembly 75-7 is also fixedly provided with a push plate 75-7-1 to facilitate the movement of pushing the food. The goods way discharging device 75 is arranged between the goods shelf 74 and the side wall of the heat preservation cabinet body 71, and is suitable for the preferred mode that 2 goods shelves 74 are oppositely arranged, 2 sets of goods way discharging devices 75 are arranged, and 1 set of goods shelves 74 and the corresponding side wall of the heat preservation cabinet body 71 are respectively arranged between the goods shelves 74 and the corresponding side wall.

The goods inlet and outlet device 76 is used for conveying heated food input from the goods inlet 71-1 of the insulated cabinet body 71 to each goods channel of the goods shelf 74 for insulated storage during use, and conveying the food pre-stored on the goods channel to the goods outlet 72-1 of the insulated cabinet door 72 for being taken by a paid customer by matching with the goods channel goods outlet device 75 during selling.

Referring to fig. 14, as a specific implementation manner, the cargo in-out device 76 mainly comprises an upper screw 76-1, a lower screw drive motor 76-2 for driving the upper screw 76-1 to move, a front screw 76-3 in transmission connection with the upper screw 76-1, a front screw drive motor 76-4 for driving the front screw 76-3 to move, a left and right transmission conveyor 76-5 in transmission connection with the front screw 76-3, and a left and right transmission conveyor drive motor 76-6 for driving the left and right transmission conveyor 76-5 to move. Preferably, the upper and lower lead screw driving motors 76-2 are fixedly arranged in a lower heat insulation area in the heat preservation cabinet body 71, so that the upper and lower lead screw driving motors 76-2 with relatively high power can avoid working at high temperature, the up and down movement lead screw driving motor 76-2 can work more reliably, and the service life is prolonged. In accordance with a preferred embodiment in which 2 shelves 74 are provided to face each other, the cargo loading/unloading device 76 is provided in an empty space between the 2 shelves 74.

The heating device 73 of the thermal insulation cabinet 7, the conveyer belt driving motor 75-3 of the goods outlet device 75 of the goods passage, the upper and lower screw rod driving motor 76-2 of the goods outlet device 76, the front and rear screw rod driving motor 76-4 and the left and right transmission conveyer belt driving motor 76-6 are all electrically connected with the electric cabinet 5.

The using method and process of the automatic meal vending machine for the railway passenger car of the embodiment are briefly described as follows:

the food is frozen and stored in the freezer 1, when the meal is not at the peak of eating, after the customer selects the food and finishes payment through the human-computer interaction device 4, under the control of the electric cabinet 5, the food pushing and dropping device 15 of the freezer 1 pushes the food appointed by the customer and stored on the food shelf 14 to drop onto the food conveying device 16, the food conveying device 16 transfers the food purchased by the customer to the microwave oven 3 through the delivery flange 11-2 and the automatic door 32 of the microwave oven 3 for heating, and the heated food is pushed to the goods taking port 21 of the microwave oven outer cover 2 through the automatic door 33 and taken away by the customer.

In a set period before a meal peak, the food is heated in advance by the microwave oven 3 and is sent to the heat preservation cabinet 7 for heat preservation and preservation, specifically, the food heated by the microwave oven 3 falls onto a goods channel of a goods shelf 74 matched with the goods inlet 71-1 through a food conveying automatic door 35 and a goods inlet 71-1 of the heat preservation cabinet 7 by a left and a right conveying devices 36 of the microwave oven 3, the food input to the goods channel is conveyed to a left and a right conveying belts 76-5 of a goods inlet and outlet device 76 by a goods channel goods outlet device 75, when the food is loaded, the left and the right conveying belts 76-5 of the goods inlet and outlet device 76 move, so that the input food is effectively transferred to the left and the right conveying belts 76-5 of the goods inlet and outlet device 76 on the goods channel corresponding to a goods shelf 4 matched with the goods inlet 71-1 of the heat preservation cabinet 71, then the goods outlet device 76 drives a screw rod 76-2 to drive a screw rod 76-1 to move up and down by an up and down screw rod drive motor 76-2, the front and rear screw rod driving motor 76-4 drives the front and rear screw rod 76-3 to move, so that the goods in and out device 76 moves to the corresponding goods channel of the shelf 74, then the food is conveyed to the goods channel set by the shelf 74 through the movement of the left and right conveying conveyer belts 76-5 to be stored, and the operation is repeated until the set number of heated food is stored in the heat preservation cabinet 7. The heating means 73 keeps the temperature inside the thermal container 7 substantially at the set temperature during the preservation of the meal. During the peak of eating, except that microwave oven 3 can directly output the heated food, the goods channel delivery device 75 in the thermal insulation cabinet 7 is movably matched with the delivery device 76, and the food stored in the thermal insulation cabinet can be quickly delivered out from the delivery port 72-1 on the thermal insulation cabinet door 72 for customers to take, so that the technical problems that the food speed is low, the waiting time of the customers is long and the use requirements cannot be effectively met due to the fact that the food heated by the microwave oven is output one by one when the peak of eating is carried out by the traditional similar vending machine can be effectively solved.

(example 2)

See fig. 15, the food vending machine for the passenger train of this embodiment is the same as embodiment 1 in other respects, and the difference lies in that a set of microwave oven housing 2, microwave oven 3 and freezer 1 is added on the right side of the thermal insulation cabinet 7 of embodiment 1, and the vending machine after cascading like this has a faster delivery speed in use and a larger storage and delivery amount, and can meet the needs of more customers for purchasing food.
