[0033] The lunch box introduction port of the round soup and noodle box sorter D2 is a round shape 291, and the other structures and working steps are the same as those of the square lunch box sorter C2, and will not be described repeatedly here to save space.

[0034] In order to quickly take out the leftovers in the food storage bucket, a leftover food taking-out port 224 is provided at the base 202 of the bottom placing seat A2. A special leftover food tray is put into the food taking-out port onto the food conveyor belt, and the bucket position switch 14 is operated to discharge the leftovers. Another method is to take out the food bucket from the unit, discharge the leftovers in a special food bucket cleaning machine and wash them.

[0035] The three tableware sorters are respectively installed on the bottom delivery seat A2 to form a multi-meal box delivery device 2. The multi-meal box delivery device 2 is placed on the conveyor belt of the meal delivery machine and is synchronously controlled by the meal delivery machine unit.

[0036] Attached Figure 7 It is a schematic diagram of placing a multi-meal box dispenser on the meal transport conveyor belt 295 of the meal dispensing machine.

[0037] Attached Figure 8 This is a schematic diagram of a multi-meal box dispenser and a meal dispenser being matched together.

[0038] Attached Fig. 9 This is a schematic diagram of the lunch box style. A combination dinner plate 294 is used for on-site lunch and dinner, a disposable square fast food box 293 is used for take-away lunch and dinner, and a disposable soup and powder box 292 is used for breakfast and supper.

[0039] The three types of tableware sorters are respectively installed on the bottom placement seat A2 to form a multi-meal box dispenser 2. The multi-meal box dispenser is placed on the conveyor belt of the meal dispenser and is controlled by the meal dispenser to work synchronously. It can separate rice, vegetables, soup, porridge, etc. It can also separate breakfast, lunch, dinner and supper. One machine has multiple uses, realizing the multi-functional meal dispensing function of the meal dispenser.

[0040] The functions of each mechanism of the present invention have been introduced one by one above. Now, the use of the multi-meal box dispenser is systematically described:

[0041] First, connect the power supply and signal lines of the multi-meal box dispenser to the meal dispenser, open the covers of each sorter, and put the corresponding tableware into each sorter unit: there are combined meal boxes, disposable square fast food boxes and disposable round soup and powder boxes, then close the covers of each machine, press the start button on each control panel, and each sorter will be in standby mode; when the signal reaches the combined meal box sorter B2, the signal starts the plate picking motor to drive the guide plate spiral wheel to rotate and directly drop the meal plate onto the conveyor belt 295 below. When the signal reaches the square lunch box sorter C2, the square lunch box delivery device starts immediately and runs towards the airdrop area 209. When the manipulator opening device 222 is near the airdrop area and hits the conical stopper 223 set on the reinforcing bar, the box transport slider 211 moves to both sides. At the same time, the manipulator rotator 217 rotates under the action of the rack box transport slide rail 210, and the mechanical finger 212 rotates synchronously to drop the lunch box onto the conveyor belt 295 below, and then returns to its position. After the delivery device 207 returns to its position, the box picking drive motor 280 immediately continues to work and drives the box picking cam 279 to rotate to guide the lunch box onto the square mechanical finger 212 for standby, waiting for the next work instruction, and a workflow ends.

[0042] When the signal is sent to the round soup powder box sorter D2, the working steps are the same as those of the square sorter.

[0043] A low-box sensor is provided on the inner plate of the lunch box storage box. When there are not enough lunch boxes and plates in the storage box, the low-box and low-plate sensor activates the alarm on the control panel to sound an alarm, indicating that tableware needs to be added.

[0044] This unit can work synchronously with the automatic meal dispensing machine. There is no need for staff to guard the machine for a long time, which saves labor intensity. It has the characteristics of small body, large box storage capacity, low failure rate and easy operation.

[0045] The above is a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
