Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, and more specifically to a grooving error-proofing device. Background Art

[0002] Automated loading and unloading systems for liquid materials are widely used in fields such as chemical processing and food processing. These systems typically consist of several tanks storing different types of liquids, connected to various points of use via a network of pipes. To prevent accidents caused by misoperation resulting from the mixing of different liquids, a number of safety measures and technologies are currently available, such as color coding, tag recognition, and RFID. While these technologies have improved operational safety and accuracy to a certain extent, they still have limitations and room for improvement.

[0003] Currently, the industry's commonly adopted methods for preventing incorrect material loading include: physical isolation—isolating different material delivery routes through physical barriers. This method is simple and reliable, but lacks flexibility and has limited adaptability to complex and changing production lines; manual inspection—relying on workers' experience and visual judgment to confirm the correct material flow. While this method can handle some special situations, it is susceptible to human factors and is costly; and automatic control systems—using intelligent devices such as sensors and PLC controllers to achieve automatic monitoring and adjustment. These systems offer high accuracy and stability, but require large initial investments and relatively high maintenance costs. Each of these methods has its advantages, but they also present certain challenges in practical applications, such as poor cost-effectiveness, insufficient reliability, and inconvenient operation. While existing technical means of preventing incorrect material loading can reduce the incidence of errors to a certain extent, they each have inherent challenges, such as high cost, low flexibility, and excessive reliance on manual labor, making them difficult to fully meet the efficiency, safety, and economic needs of modern industry.

Otherwise, it will remain closed until a new legal command is received.

[0016] Furthermore, a display screen is fixedly mounted on the lower front side of the device outer shell, and an indicator light is fixedly mounted on the side of the device outer shell located at the RFID reader.

[0027] A lower mounting member 11 is fixedly installed below the connecting pipe 6, and an upper mounting member 10 is fixedly installed at the lower end of the solenoid valve 9. The lower mounting member 11 and the upper mounting member 10 are fixedly connected by bolts. The operator can fix the solenoid valve 9 on the connecting pipe 6 through the upper mounting member 10 and the lower mounting member 11. The solenoid valve 9 can control the opening or closing of the connecting pipe 6. At the same time, the outer shell 3 of the device and the solenoid valve 9 can be removed as a whole by simply removing the bolts of the upper mounting member 10 and the lower mounting member 11, which is convenient for maintenance.

[0028] A sealing cover 7 is rotatably mounted on the upper front side of the connecting pipe 6, and an induction switch 19 is fixedly mounted on the lower front side of the connecting pipe 6. The sealing cover 7 can be flipped over to expose the connection port of the connecting pipe 6. When the sealing cover 7 is in a closed state, the induction switch 19 contacts the sealing cover 7 and no signal is transmitted. When the sealing cover 7 is flipped and separated from the connecting pipe 6, the induction switch 19 detects a separation signal and sends a signal to the central control system, making it convenient for management personnel to monitor and control the connecting pipe 6.

[0029] A pressure sensing element 14 is fixedly installed in the middle of the rear side of the connecting pipe 6. The pressure sensing element 14 can continuously monitor the pressure difference between the two ends of the valve. If there is any abnormality, the alarm information will be immediately uploaded to the superior management platform.

A lithium battery 17 is located inside the device housing 3 at the position of the battery cover 4. The lithium battery 17 can power the internal components. The wireless antenna 2 can increase the signal strength and can communicate with the central control system via a wireless network, thereby controlling the internal components.

[0031] A square slot is provided on the front side of the RFID reader 18, and the RFID tag 13 is attached to the front side of the RFID reader 18. When the central control system sends an opening signal to the solenoid valve 9, the RFID reader 18 is activated to scan the RFID tag 13 set on the front side. If the information of the RFID tag 13 matches the expected information, the main control chip 16 will allow the solenoid valve 9 to open for loading. Otherwise, it will remain closed until a new legal command is received.

[0032] A display screen 5 is fixedly installed at the lower front side of the device outer shell 3, and an indicator light 1 is fixedly installed on the side of the device outer shell 3 located at the RFID reader 18.

During production activities, the feed pipe and the processing device can be connected in advance through the connecting pipe 6. At the same time, according to the information of the liquid inside the feed pipe, the corresponding RFID tag 13 is attached to the front side of the RFID reader 18. When loading starts, the operator first selects the target liquid material type through the handheld terminal and sends an instruction to the central control system. When the central control system sends an open signal to the solenoid valve 9, it activates the RFID reader 18 to scan the RFID tag 13 set on the front side. If the information of the RFID tag 13 matches the expected one, the main control chip 16 will allow the solenoid valve 9 to open for loading, otherwise it will remain closed until a new legal command is received. This design not only ensures the safety of operation, but also simplifies the traditional manual verification procedure and reduces the probability of error. In addition, each device is equipped with a pressure sensing element 14 to detect the change of pipeline pressure in time. Once an abnormality is found, it can be immediately fed back to the control system for timely processing.

[0034] The model of the RFID reader 18 is TRF7960, the model of the main control chip 16 is STM32F103RCT6, and the specification of the solenoid valve 9 is DN50PN16. The RFID reader 18, the main control chip 16, the solenoid valve 9, and the pressure sensing element 14 are all common standardized products on the market. Different brands or models of products can be replaced according to actual needs without affecting the compatibility and performance of the overall system.
