Example 1:

this embodiment provides an automatic device of beating dishes in dining room. As shown in fig. 1, the diner selects dishes from the dish taking window, then the dish supplying mechanism 4 pushes out a dish 7 to fall on the dish receiving platform 22, the dish receiving platform 22 starts from the starting point, and sequentially passes through all the dish taking mechanisms 1 under the cooperation control of the controller 6 and the positioning assembly 3, the dishes selected by the diner are received on the dish, finally, the dish receiving platform 22 runs to the end point, and the diner takes the dish away and then the dish receiving platform 22 returns to the starting point, so that one movement is completed. And if the staff have subsequent meals, repeating the actions.

Fig. 2 shows the structure of the serving basket 5, and the serving basket 5 should be filled with enough dishes before the system is used for serving, and then the serving basket 5 can be mounted on the serving mechanism 1. Firstly, a switch sliding plate 51 at the bottom of the vegetable containing barrel is closed, the vegetable containing barrel 5 is vertically placed, then vegetables can be loaded into the vegetable containing barrel 5, when enough amount of vegetables in the vegetable containing barrel 5 is reached, a round vegetable pushing plate 52 with certain elasticity at the periphery is firstly placed, then the top end of the vegetable containing barrel 5 is covered by a vegetable containing barrel cover 53, and finally screws are screwed in to ensure that no gap exists between the vegetable containing barrel cover 53 and the top end of the vegetable containing barrel 5.

Fig. 7 shows the structure of the vegetable beating mechanism 1 when the vegetable containing barrel is not installed. After the vegetables in the vegetable containing barrel 5 are placed and the barrel cover is closed, the vegetable containing barrel 5 is laid on the vegetable containing barrel bearing frame 11, the convex part on the vegetable containing barrel 5 corresponds to the corresponding concave pit of the barrel frame 11 to realize angle positioning, the air pipe 131 is inserted into the hole in the middle of the barrel cover 53, the switch sliding plate 51 carried by the vegetable containing barrel 5 is shifted to an opening state, before the angle correction is finished, the sealing component 12 needs to finish the angle correction, namely the rotating motor 121 can rotate a given angle to enable the opening of the bottom end baffle plate 122 to be superposed with the vegetable outlet at the bottom end of the vegetable containing barrel 5, so that the vegetables fall out; two containing vegetable buckets 5 on the left and right can be arranged on one bucket rack 11, and in order to ensure that different vegetables cannot be stacked at the same position, the vegetables in the two containing vegetable buckets 5 on the left and right on the bucket rack 11 are the same, so that the same vegetable can fall out from a selected one of 4 openings of the two containing vegetable buckets on the left and right.

Fig. 8 shows the structure of the disc supply mechanism 4. When a diner uses APP to order a meal, the dish supply mechanism 4 starts to work, firstly, the rope motor 43 controls the dish storage box 411 to ascend through the lifting rope 44, so that the openings at the other sides of the dishes in the dish pushing assembly 42 and the dish storage box 411 and the dish storage rack 412 are completely corresponding, and then the dish pushing assembly 42 pushes the dish 7 out of the dish storage box 411 and falls onto the dish receiving table 22 as shown in FIG. 9. Dish storage box 411 is the design of laminar, and every layer all can be deposited a dish, and rope motor 43 control dish storage box 411 rises the height of one deck each time can.

Fig. 10 shows the structure of the meal dispensing assembly 2, the positioning assembly 3 and the controller 6. The tray 7 is pushed out of tray storage bin 411 and falls into tray receiving station 22, and then lead screw motor 24 is operated to move tray receiving station 22 forward. Because the lead screw motor 24 can precisely control the movement of the plate receiving platform, and the controller can receive the information of the dishes selected by the diner and control the sensor set 31, the plate receiving platform 22 only stops at the dish placing mechanism 1 corresponding to the selected dishes, if the dishes are not selected, the plate receiving platform 22 can pass through at a higher speed, the time can be saved, and the positioning component 3 can precisely position the position where the plate receiving platform 22 needs to stay, thereby reducing the loss caused by the dishes not falling into the plate to the maximum extent.

As shown in fig. 11, when the dish receiving platform 22 stops at the corresponding dish serving mechanism 1, the dish serving mechanism 1 determines which opening the dish should be poured from according to the logic control, and once the previous dish serving mechanism has poured the dish at a certain position, the subsequent mechanism will automatically change the opening and fall out from the other openings. Fig. 12 illustrates the movement of the closure assembly 12 when dishes fall out of one of the openings. When pouring dishes, firstly, the motor controls the sealing component 12 to rotate towards a certain direction, so that the opening of the baffle 122 at the bottom end of the dish containing barrel of the sealing component 12 is opposite to the opening at the bottom of the dish containing barrel 5, the dishes can fall out, the quantity of the poured dishes is determined by controlling the opening time, and a user of the device can adjust the quantity of the poured dishes according to the self condition; when the vegetable is opened, the vegetable pushing air pump 132 starts to pump air through the air pipe 131, the vegetable pushing plate 52 moves through the air pressure effect, and enough vegetables can fall out from the opening each time the vegetable is opened.

Fig. 13 shows a block diagram of the control process of the controller 6 for controlling the movement of the dish receiving station 22 and the corresponding action of the automatic dish serving mechanism 1. After the diner uses the APP to order the dishes, the program controller immediately acquires the type information of the dishes and initializes a global variable i to 1, and the global variable determines the action execution condition of the automatic dish ordering mechanism 1. After the tray receiving station 22 has moved, the system determines whether the dish has been selected before each pass through an automatic serving mechanism. If not, directly passing through; if the dish receiving table 22 is selected, the dish receiving table stays at the corresponding position under the control of the sensor group 31, and then the controller 6 checks the value of the global variable i, wherein the corresponding i is 1, 2, 3, or 4, and the controller determines which rotating motor in the automatic dish serving mechanism 1 moves in which direction, so that the corresponding opening is opened to facilitate the falling of dishes. In order to avoid the dish from being mixed when the dishes fall to the same position, the program controller controls the value of i to be added by 1 after each dish-serving action is executed, so that the value of i is different when the dish-receiving table 22 stays at the corresponding position every time, and the execution action of the automatic dish-serving mechanism is different.

The tray receiving station 22 will travel to the end point after all of the automated dish placement mechanisms, and when the diner removes the tray, the tray receiving station 22 will return to the start point under the control of the lead screw motor 24.

The tray storage box 411 can store 20 to 30 trays at a time, when the trays are to be used up, the limit switch on the tray storage rack 412 is triggered to remind the worker, the worker controls the rope motor 43 to enable the tray storage box 411 to fall back, then the trays are inserted into each layer of the tray storage box 411, and then the rope motor 43 is started to enable the tray storage box to work again.

If the dishes in one of the dish containing barrels 5 are used up, the limit switch on the dish containing barrel 5 is triggered to remind a worker, the worker firstly unloads the air pipe 131 from the barrel cover 53, closes the switch sliding plate 51, takes down the dish containing barrel 5 from the barrel frame 11, and installs the dish again after the dishes are loaded.

The height difference between the dish serving mechanism 1 and the dish receiving table 22 is proper, so that the dish can not be splashed out, and the dish can fall down at a sufficient distance, and the height difference is 10-15 cm.

Because the device is a dish serving device and has high requirement on sanitation, the parts of the dish containing barrel 5, the dish pushing plate 52, the baffle plate 122 at the bottom end of the dish containing barrel and the like which are directly contacted with dishes are cleaned after the device is used every time.
