Design and realization of unmanned vending machine for fresh fruits and vegetables

Design and implementation of unmanned vending machines for fresh fruits and vegetables. Guangdong unmanned vending machines have two door control parts, which are mainly placed on the outer frame of the first door. Displays, coin-operated machines, reclaiming doors, etc. are placed inside the unmanned vending machines. Set up an insulation door. The interior of the vending machine is generally divided into upper and lower parts. The upper part is mainly used for storing fresh fruits and vegetables. The lower part is mainly used for storing fresh fruits and vegetables. The upper and lower parts are separated by partitions. The entire box body is made of materials with good heat preservation performance, together with the heat preservation door and the partition to form a closed space, so that the storage system can play a good role in keeping fresh. Weigh the vegetables and fruits in advance, put them in the fresh-keeping box, spray them with a QR code and put them into the vending machine's material channel. After the consumer pays, the control system issues an instruction to the motor to rotate the designated fruit and vegetable feeder to the blanking position. The blanking device will fall into the blanking box and the consumer will take it away through the reclaiming door. The fresh fruit and vegetable unmanned vending machine is equipped with a supporting mechanism at the bottom of each layer of the material channel (Figure 1 is a schematic diagram of the supporting mechanism). The supporting mechanism mainly includes an upper rotating arm, a lower rotating arm and a rotating shaft. The upper and lower rotating arms have the same structure. Connect when installed The two ends of the shaft are embedded in the material channel frame and the flange part directly supports the fruit and vegetable preservation box. In order to store fresh fruits and vegetables, the lowermost part of the material channel is guaranteed to be blank. During the blanking process, the flange of the lower boom is turned and tilted. The fruits and vegetables at the bottom of the designated material channel are dropped. In order to be able to sell a variety of fruits and vegetables, the unmanned vending machine material channel can be designed as multiple rows. There are 1 to 4 layers in each column, and 1 to 6 fresh-keeping boxes are placed on each layer in turn. The frame of the multi-row material channel is fixed on a turntable by bolts at the upper and lower positions to facilitate the overall removal of fruits and vegetables or to replace the material channel. The turntable is connected to the motor through a coupling at the top. It can be driven by the motor through the thrust bearing at the bottom to rotate on the partition. The weight of the turntable together with the material channel, fruits and vegetables is borne by the partition below. When the supporting mechanism is installed to the material channel frame The rotating shaft needs to pass through the lifting rod. Therefore, the lifting rod must be combined with the diameter of the rotating shaft to machine a specific shape of the sliding groove so that the lifting rod will force the rotating shaft to move up and down along the slide rail of the material channel frame under the push of the incomplete cylindrical cam. The unmanned vending machine based on the material channel frame originated in the western developed countries. Now this fast and convenient sales method has been accepted and recognized by more and more people [2'. At present, unmanned vending machines have been widely used in many aspects such as selling candy, beverages, cigarettes, newspapers, etc. However, unmanned vending machines that require refrigerated and fresh-keeping products such as fresh fruits and vegetables are still rare in China. The above is the whole content of the article introduced by the unmanned vending machine in Dongguan. If there are any shortcomings, please forgive me! For reference and learning purposes only!
