Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in figure 1, the invention relates to an intelligent vegetable vending machine which comprises a shell 1, a vegetable storage box 2, a conveying belt 6, a vegetable taking weighing platform 7 and a vegetable returning weighing platform 11. The dish taking window 10 and the intelligent operation panel device 8 are positioned at the front part of the machine shell 1, and the dish returning window 13 and the vegetable filling window 15 are positioned at the top part of the machine shell 1. The rear part of the dish returning weighing platform 11 is provided with a dish returning slide way 14 so that the vegetables 3 can slide back to the dish storing box 2.

Filling vegetables 3 by a merchant as shown in figure 1, opening the filling window lock 16, turning over the vegetable filling window 15, and pouring the vegetables 3 into the vegetable storage box 2. The vegetable filling window 15 and the filling window lock 16 are closed, and the corresponding vegetable 3 price is set on the intelligent operation panel device 8.

As shown in figure 1, when a customer purchases vegetables 3, the weight of the vegetables 3 to be purchased is set on the intelligent operation panel device 8, the driving motor 5 is started to drive the driving wheel 4 to rotate, the conveying belt 6 drives the vegetables 3 to slide forwards from the outlet of the vegetable storage box 2 and fall into the vegetable taking weighing platform 7, and when the weighing mass of the vegetable taking weighing platform 7 is close to the input mass of the customer, the driving motor 5 is turned off. After the customer pays the corresponding payment through the code scanning, the dish taking window lock 9 is opened, the customer takes the vegetables 3 out of the dish taking window 10, and the dish taking window lock 9 is closed automatically after the numerical value of the dish taking weighing platform 7 returns to zero, so that the transaction is completed.

As shown in fig. 2, when the customer wants to return vegetables 3, the customer clicks a dish return button on the smart operation panel device 8. After the customer pays the corresponding payment of the existing vegetables by scanning the code, the dish taking window lock 9 and the dish returning window lock 12 are opened simultaneously. The customer takes the vegetables 3 out of the vegetable taking window 10 and puts the vegetables into the vegetable returning weighing platform 11 through the vegetable returning window 13. The system automatically compares the number of the dish taking weighing platform 7 to be reduced with the number of the dish returning weighing platform 11 to be increased, and checks whether the quality of each dish returning is completely equal. After the operation is finished, the customer clicks a dish returning completion button on the intelligent operation panel device 8 to close the dish returning window lock 12, and money to be returned is automatically returned to the customer account. The returned vegetables 3 return to the vegetable storage box 2 through the vegetable return slide way 14, and the customer takes the needed vegetables 3 out of the vegetable taking window 10.

As shown in fig. 2, when a customer needs to replace a vegetable 3, a replacement button is clicked on the smart operation panel device 8. After the customer pays the corresponding payment of the existing vegetables by scanning the code, the dish taking window lock 9 and the dish returning window lock 12 are opened simultaneously. The customer takes the vegetables 3 out of the vegetable taking window 10, puts the vegetables 3 into the vegetable returning weighing platform 11 through the vegetable returning window 13, and simultaneously the conveyor belt 6 starts to supplement the vegetables 3 with the same quality as the vegetable returning weighing platform 11. After the customer is satisfied with all the vegetables 3, the dish returning window lock 12 is closed by clicking the replacement completion button on the intelligent operation panel device 8. The replaced vegetables 3 are returned to the vegetable storage box 2 through the vegetable return slide way 14, and the customer takes the needed vegetables 3 out of the vegetable taking window 10.

The opening at the bottom end of the vegetable storage box 2 corresponds to the other transmission end of the transmission belt 6. The vegetable 3 in the vegetable storage box 2 can accurately and quickly fall into the top end of the conveying belt 6, and the working efficiency of the belt conveying device is effectively improved.

As shown in fig. 3, the smart operation panel device 8 includes a control panel 801, a smart display 802, and a PLC controller 803, and the control panel 801 and the smart display 802 are electrically connected to the PLC controller 803. The control panel 801 can facilitate a customer or a user to send instructions to the PLC controller 803, and facilitate acquisition of signals external to the PLC controller 803; the intelligent display 802 can display the payment code or the dish information, so that the user can complete the transaction smoothly; the PLC controller 803 is a micro intelligent controller, which can perform a plurality of intelligent controls by instructions, effectively improving the work efficiency during transactions.

The PLC controller 803 is programmed using a ladder diagram. The arrangement can facilitate the programming control of a user and effectively improve the programming efficiency of the user.

The dish returning slide way 14 is in an inclined state. The arrangement can ensure that the vegetables 3 in the dish returning weighing platform 11 slide into the dish storage box 2 along the inclined plane rapidly, thereby effectively improving the recovery efficiency of the vegetables 3.

The dish taking window lock 9, the dish returning window lock 12 and the filling window lock 16 are respectively electric control locks. The electric control lock is simple in structure, convenient to use, high in safety level and capable of effectively facilitating control of the PLC 803.

The present invention is illustrated by way of example and not by way of limitation. Other variants and modifications will be apparent to those skilled in the art in light of the foregoing description, and it is not necessary or exhaustive to have all embodiments disclosed, and obvious variations and modifications are possible within the scope of the invention.
