[0020] The top of each layer of the goods channel 5 is provided with an adjusting rod 6, and the distance between the upper and lower goods channels 5 can be adjusted by the length of the adjusting rod, thereby improving the variety of goods. Small items can use three, four, five or more layers of goods channels, while large objects can use single or double layers of goods channels. The connecting plate 7 is fixedly connected to the connecting position of the long conveying belt 51 and the short conveying belt 52, and the upper end of the connecting plate 7 is provided with a photoelectric sensor 8. Through the design of double-flow pipeline parallel processing and multi-layer commodity storage and the cooperation of the photoelectric sensor 8, the processing efficiency and commodity storage capacity of the vending machine are significantly improved. Moreover, each layer of the goods channel 5 is an independent individual, and the conveying of goods in each layer can be adjusted according to the needs of the user. Therefore, the number of layers of the automatic code scanning vending machine can be increased or reduced according to the demand, thereby improving the flexibility of the automatic code scanning vending machine during installation.

[0021] In practical applications, four, five, six or more layers or one or two layers can be achieved. Because each layer of the goods channel 5 can independently complete the conveying adjustment of the goods.

[0022] Further comprising a frame 3, which is arranged at the outer end of the goods channel 5, and a transparent protective cover 4 is arranged on the frame 3. The transparent protective cover 4 is provided with a goods taking port near the position where the goods are taken. The frame 3 provides support for the transparent protective cover 4, effectively preventing dust, dirt and other pollutants from entering the goods channel 5, keeping the goods clean. The goods taking port is arranged near the position where the goods are taken, which is convenient for the buyer to quickly take the goods and operate more conveniently.

[0023] The driving mechanism 53 comprises a plurality of stepping motors 531, each of which is correspondingly installed at the lower end of the long conveying belt 51 and the short conveying belt 52. The output shaft of the stepping motor 531 is fixedly connected with a driving wheel 532. The surface of the driving wheel 532 is drivingly connected with a synchronous belt 533. One end of the synchronous belt 533 is drivingly connected with a driven wheel 534. The inner cavity of the driven wheel 534 is fixedly connected with a roller (not shown in the figure). The long conveying belt 51 and the short conveying belt 52 are arranged on the surface of the roller. The driving mechanism 53 serves as the power source of each layer of the goods channel 5, converts electric energy into mechanical energy, and controls the synchronous driving of the two stepping motors 531 of each layer through the electric control box 2. Then the output shaft of the stepping motor 531 is connected with the driving wheel 532. The rotation of the stepping motor 531 is transmitted to the driving wheel 532 through the output shaft, driving the driving wheel 532 to rotate. Then the long conveying belt 51 and the short conveying belt 52 are matched with the roller. Therefore, each stepping motor 531 can drive the long conveying belt 51 and the short conveying belt 52 to rotate, thereby driving the position of the goods to move. At the same time, during the purchase of goods, when the goods pass through the photoelectric sensor 8, the PLC module receives the signal according to the set time or conveying distance to start and stop the two stepping motors 531. The stepping motor 531 of the long conveying belt 51 will stop first, generally taking 0.5 to 1 seconds to stop. The stepping motor 531 of the short conveying belt 52 will stop operating later, because the short conveying belt 52 needs to take the purchased goods to the position where the purchaser can conveniently take the goods. The purchaser will take a longer step from the position of scanning the code and paying to the position of taking the goods, and will take more time, generally 2 to 5 seconds, until the purchaser moves to the position of taking the goods. Then the stepping motor 531 on the short conveying belt 52 will stop driving.

[0024] The lower surface of each layer of the goods channel 5 is symmetrically provided with a first illuminating lamp 9. The first illuminating lamp 9 is located above the bottom layer of the goods channel 5. The top of the adjusting rod 6 is fixedly connected with a cross rod 10. The lower surface of the cross rod 10 is provided with a second illuminating lamp 11 for providing illumination for the top layer of the goods channel 5. The first illuminating lamp 9 is symmetrically installed on the lower surface of each layer of the support frame 1, which can provide uniform illumination for each layer of the goods storage area, ensuring that the goods are clearly visible. The second illuminating lamp 11 is installed on the lower surface of the cross rod 10, which is specially designed to provide illumination for the top layer of the goods channel 5, making up for the insufficient illumination of the top layer due to the height problem. Adequate lighting conditions can improve the recognition rate of each layer of goods.

[0025] In specific use, after the power is turned on, the power switch of the electric control box 2 is turned on, then the PLC module receives the signal, and the working of each layer of the goods channel 5, the driving mechanism 53, the photoelectric sensor 8, the first illuminating lamp 9 and the second illuminating lamp 11 can be controlled, then according to the selected goods position of the user, the corresponding level of the long conveying belt 51 and the short conveying belt 52 is started, the driving force is provided by the step motor 531, then through the matching of the driving wheel 532, the synchronous belt 533 and the driven wheel 534, the step motor 531 drives the long conveying belt 51 and the short conveying belt 52 to operate, the long conveying belt 51 is used for storing goods, the longer the synchronous belt 533 is, the more goods are stored, and the short conveying belt 52 is used for driving the goods purchased by the purchaser to the position where the goods are taken by the purchaser, so that the goods can be quickly and accurately conveyed from the storage area to the goods outlet through the cooperation of the long conveying belt 51 and the short conveying belt 52, the waiting time of the user is shortened, and the photoelectric sensor 8 can detect the conveying state of the goods in real time, so that the goods are ensured to be smoothly conveyed to the goods outlet.

[0026] It is explained that in the embodiment, the long conveying belt 51 and the short conveying belt 52 constitute double-pipeline conveying goods, and the driving structure of the double-pipeline has various modes, which can be a belt wheel driving or a chain wheel driving or a screw guide rail driving or a gear rack driving. In the embodiment, the driving mechanism 53 is a speed-regulating motor or a step motor or a servo motor.

[0027] The driving of the driving mechanism 53 of each layer is that after the consumer scans the code and pays, the PLC module receives the signal, the speeds of the two driving mechanisms 53 are synchronous, but the two driving mechanisms 53 stop in sequence, the driving mechanism 53 driving the long conveying belt 51 stops operating after 0.5 to 1 seconds, which is just enough to convey the goods on the long conveying belt 51 to the short conveying belt 52, then the driving mechanism 53 driving the short conveying belt stops operating after 2 to 5 seconds, and the goods purchased by the purchaser are driven to the position where the purchaser can conveniently take the goods. At the same time, the purchaser also moves to the position of the goods outlet.

[0028] It is explained that in the embodiment, three goods channels are designed and applied, and each goods channel can sell hundreds or thousands of goods because the design is large. For example, after a large watermelon is sold out, the program parameters can be changed to sell mineral water, after the mineral water is sold out, the parameters can be changed to sell milk tea, after the milk tea is sold out, the parameters can be changed to sell cooling sugar water. In addition to selling single goods, several kinds of goods can be mixed and sold together, for example, beer and peanuts, and cold pig ear are placed in the same dish to become a group of goods and are conveyed to the consumer. The price set by the program is the sum of the prices of the several kinds of goods.

[0029] Figure 5 The functions of the modules are as follows:

[0030] The mobile phone code scanning module

[0031] Function: Consumers use their mobile phones to scan the QR code posted on the protective cover, select the desired goods through the relevant program, and transmit the goods information to the PLC.

[0032] Technical Implementation: A special QR code scanning application needs to be developed on the mobile phone. This application should be able to identify the QR code information and send it to the PLC through appropriate communication methods (such as Bluetooth, Wi-Fi, etc.). Meanwhile, the QR code encoding needs to include detailed information about the goods, such as the product number, name, specifications, etc.

[0033] Application Scenario Example: In the automatic vending machine scenario, consumers use their mobile phones to scan the QR code to select the beverages, snacks, or other goods they want to purchase. The mobile phone sends the goods information to the PLC for subsequent processing.

[0034] PLC (Programmable Logic Controller) Module

[0035] Function: Receives goods information from mobile phone scanning and detection signals from photoelectric sensors, performs logical operations and processing on these input signals according to pre-written programs, and then outputs control signals to control the running state of motors and other execution devices.

[0036] Technical Implementation: PLC needs to have corresponding communication interfaces (such as RS-232, RS-485, Ethernet interface, etc.) to receive signals from mobile phone scanning and photoelectric sensors. Programmers need to use specific programming languages (such as ladder diagram, instruction table, etc.) to write control programs to implement the processing of input signals and the control logic of motors.

[0037] Application Scenario Example: When a consumer selects a certain goods through mobile phone scanning, the PLC receives the goods information and waits for feedback from the photoelectric sensor. When the photoelectric sensor detects that the goods start to move or reach the designated position, the PLC controls the operation of the motor according to the preset process, such as controlling the rotation direction, speed, and stopping time of the motor.

[0038] Motor Module

[0039] Function: Receives control signals from PLC and performs start, stop, speed adjustment, etc. operations according to instructions.

[0040] Technical Implementation: The motor needs to be electrically connected with the PLC, usually through relays, contactors, etc. electrical components to realize the control of the motor by the PLC. The type of motor (such as DC motor, AC motor, etc.) and the control method (such as variable frequency control, servo control, etc.) need to be selected according to the specific requirements of the system.

[0041] Application scenario example: In the vending machine, when the PLC receives the information that the consumer selects the goods, the motor is started to drive the double pipeline to send the goods to the delivery port. When the photoelectric sensor detects that the goods have arrived, the PLC controls the motor to stop running after a certain time or after the double pipeline runs a certain distance.

[0042] Photoelectric sensor module

[0043] Function: Use the principle of light emission and reception to detect the existence, position, shape, etc. of objects, and feed back the detected signal to the PLC. In the system, it is used to detect the state of goods, such as whether the goods pass, whether they reach the designated position, etc. so that the PLC adjusts the control strategy for the motor.

[0044] Technical implementation: There are many types of photoelectric sensors, such as the opposite type and the reflective type, which need to be selected according to the specific application scenario. The sensor needs to be connected with the PLC to transmit the detected electrical signal to the PLC.

[0045] Application scenario example: Install a photoelectric sensor in the delivery channel of the vending machine. When the photoelectric sensor detects the passing of the goods and feeds back the signal to the PLC, the PLC controls the motor to stop after N seconds according to the preset process, ensuring that the goods accurately reach the delivery port.

[0046] The present application acquires information by scanning the code with a mobile phone, and the logic is processed by the PLC, and the motor action is controlled by combining the feedback signal of the photoelectric sensor, which is the prior art.

[0047] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
