[0022] Example 1

[0023] refer to Figure 1One embodiment of the present invention provides a pre-cleaning and disinfection process for empty barrels of bottled water, comprising the following steps: Appearance inspection: Real-time inspection and identification of damage and dirtiness of empty barrels of bottled water through online visual inspection equipment, the inspection equipment comprising a high-resolution camera and an image recognition unit, when the empty barrel of bottled water moves on the transmission system, the camera captures the image of the empty barrel, the image processing unit analyzes the image to identify the degree of damage and dirtiness, and transmits the data to the control system, the control system transmits the damaged and dirty empty barrels of bottled water to the transmission system for separation and scheduling according to the inspection results, the control system analyzes and identifies the damage and removes the damaged empty barrels. The control system analyzes and identifies the dirtiness data of the empty barrel and adjusts the preset cleaning parameters; flushing: flushing is performed according to the preset cleaning parameter data, and the flushing steps include low-pressure water washing, medium-pressure alkaline washing and high-pressure water washing. The low-pressure water washing includes transferring the empty barrel of bottled water that has passed the appearance inspection to the direct spray nozzle assembly, using the first nozzle to flush the inner wall of the empty barrel of bottled water, moistening the inside of the empty barrel, and removing stains on the inner surface of the barrel. The medium-pressure alkaline washing includes applying an alkaline cleaning agent according to the three-head water jet nozzle assembly to remove grease stains in the barrel. The high-pressure water washing includes further flushing the barrel using the three-head water jet nozzle assembly. Empty barrels of bottled water can be cleaned to remove stubborn stains, impurities and foreign objects in the barrels, and the alkaline cleaning agent remaining in the medium-pressure alkaline cleaning can be removed; low-pressure disinfection: the inner wall of the empty barrels of bottled water can be disinfected at low pressure using a disinfectant; secondary appearance inspection: the online visual inspection equipment can conduct a secondary appearance inspection on the empty barrels of bottled water after disinfection, detect the uncleaned areas of the empty barrels of bottled water, and redispatch them back to the flushing area through the transmission system; the secondary appearance inspection control system can dynamically adjust the cleaning parameters based on real-time feedback, and transmit the analysis data results to the control system; data recording: the control system can record the parameters and results of each cleaning.

[0024] In some embodiments, appearance detection sensors are generally integrated into the barrel water empty barrel cleaning system by being installed at key locations of the production line, such as before the empty barrel enters the cleaning area. They can be non-contact, such as photoelectric sensors, visual sensors, or 3D scanning sensors, and the sensors are connected to the automation control cabinet, which is equipped with a programmable logic controller (PLC) or industrial PC. Through these controllers, the data collected by the sensors is processed and analyzed.

[0025] After the appearance inspection, the following inspection steps are carried out for the empty barrels of bottled water: Defect inspection: Cracks and dents: Check whether there are cracks, dents or other physical damage on the barrel body; Stains and foreign matter: Identify stains, label residues or other foreign matter on the outer wall of the barrel. Shape and size verification: Confirm whether the shape and size of the empty barrel meet the standards to ensure the efficiency of the subsequent cleaning and disinfection process; Automatic sorting: According to the test results, the system automatically sorts out unqualified empty barrels from the production line; qualified empty barrels continue to enter the next step of the cleaning process.

[0026] In one embodiment, the appearance detection step also includes an image detection step, which identifies the damage of the empty barrel of bottled water by edge detection, marks the damage position, and transmits the damage position information to the control system, which sends the damaged empty barrel of bottled water to the maintenance area. Use a high-resolution camera to capture the outer surface image of the empty barrel of bottled water. Preprocess the collected image, such as denoising, contrast enhancement, etc., to improve the image quality. Apply edge detection algorithms (such as Canny edge detection, Sobel operator, etc.) to identify edges in the image, which usually mark the boundaries of damage. Extract damaged features such as cracks, holes, depressions, etc. from the processed image. Use machine learning algorithms or preset rules to identify whether these features represent damage. Mark the identified damaged position on the image with color or symbol, and generate coordinate information or other descriptive data of the damaged position. Transmit the damaged position information to the control system; the control system receives the damaged position information. Based on the received data, the control system makes a decision to separate the damaged empty barrel of bottled water from the production line. The control system directs the robot arm or conveyor belt to send the damaged empty barrels to the processing area. Through image detection, the damaged position can be identified and located very accurately. This reduces manual involvement and improves the automation of the production line. Quickly identifying damaged barrels reduces the possibility of unqualified products entering the subsequent process and improves overall efficiency.

[0027] In this implementation, online visual inspection is used. The empty barrels of bottled water move continuously on the conveying system, and the high-resolution camera is triggered at a preset time interval or position to capture the surface image of the empty barrel. The image is transmitted in real time to the image processing unit, which uses advanced image recognition algorithms to analyze the image to identify the damage and dirtiness of the empty barrel. Image capture provides the necessary data input for image analysis, and the accuracy of image analysis directly affects the decision of the subsequent control system. The image processing unit transmits the damage and dirtiness data of the empty barrel to the control system by wire or wireless means. After receiving the data, the control system conducts a quick analysis and determines whether the empty barrel is damaged and how dirty it is according to the preset logic. The decision of the control system is based on the data provided by the image processing unit, which determines the processing flow of the empty barrel. The control system adjusts the preset parameters of the cleaning system, such as flushing pressure, flow, time, cleaning agent concentration, etc., according to the dirtiness data of the empty barrel. The control system contains a machine learning algorithm, which continuously optimizes the parameter settings based on the historical cleaning effect, and the parameter adjustment ensures that the cleaning process can be personalized for empty barrels with different degrees of dirtiness. The decision of the control system directly affects the cleaning effect and efficiency. Low-pressure water washing: First, use low-pressure water to rinse the empty barrel, moisten the inside of the empty barrel, and remove loose dirt on the surface; Medium-pressure alkaline washing: Then, use medium-pressure water and alkaline detergent to rinse, break down stubborn stains, and remove grease stains in the barrel; High-pressure water washing: Finally, use high-pressure water to thoroughly rinse the empty barrel to remove stubborn stains, impurities, and foreign matter in the barrel, and at the same time remove the alkaline detergent remaining in the medium-pressure alkaline washing to ensure the cleaning effect. The rinsing step is a direct application of the cleaning parameter adjustment. Each rinsing stage is a supplement to the previous stage, which together ensures the cleaning quality. Broken empty barrel processing process, separation scheduling: After the control system identifies the broken empty barrel, it is separated from the main cleaning process by the robotic arm or other device of the transmission system; Processing or disposal: The broken empty barrel is guided to a separate processing area for re-inspection or direct disposal.

[0028] In this implementation, the cleaning parameter data during the flushing process is adjusted and preset by the control system. According to the preset cleaning parameter data, the low-pressure water washing parameter control includes flushing pressure, and the system pressure is set in the low-pressure range (for example, 3-5bar) by adjusting the pressure control valve; flow rate, the water flow rate is controlled by the flow meter and the regulating valve to ensure sufficient coverage area and flushing effect; time, the PLC controls the duration of low-pressure water washing according to the preset time program or dirtiness data; cleaning agent, cleaning agent is usually not used at this stage. Medium-pressure alkali washing parameter control includes flushing pressure, increasing the pressure to the medium-pressure range (for example, 25-30bar), which is achieved by adjusting the pressure control valve; flow rate, adjusting the flow rate to ensure that the cleaning agent is in full contact with the stain, and the flow rate is usually adjusted according to the pressure; time, the PLC sets the time of medium-pressure alkali washing according to the type and degree of stains; cleaning agent concentration: the concentration of the cleaning agent is adjusted by the proportional mixing pump and the control valve to ensure effective chemical cleaning. High-pressure water washing parameter control includes flushing pressure, which is to increase the pressure to the high-pressure range (such as 60 bar or higher) through a high-pressure pump and a pressure regulating valve; flow rate, which is to adjust the flow rate to provide sufficient water for strong flushing, while considering the capacity of the pump and the bearing capacity of the system; time: PLC controls the time of high-pressure water washing to ensure thorough flushing without damaging the empty barrel; cleaning agent: cleaning agent is usually not used in the high-pressure water washing stage, and it mainly relies on the high-pressure hydraulic effect.

[0029] The cleaning effect is monitored in real time through sensors. Based on the real-time monitoring data, the PLC can automatically adjust the parameters to optimize the cleaning effect. Using the accumulated historical data, the cleaning parameters are optimized through algorithms to improve efficiency and quality. The operator can manually adjust the cleaning parameters through the HMI to deal with special situations or perform system debugging.

[0030] In some embodiments, low-pressure water washing includes a low-pressure water pump, a water storage tank, and a pipeline system. The low-pressure water pump is used to generate a low-pressure water flow. The water storage tank stores a clean water source. The pipeline system is used to connect the water pump, the water storage tank and the nozzle, and a low-pressure nozzle suitable for the inner wall of the empty barrel is selected, such as a fan nozzle or a rotating nozzle. Check to ensure that all empty barrels are operating normally and there is no leakage. Check whether the nozzle is clean and not blocked, and ensure that the water source is clean and free of impurities. The operating steps of low-pressure water washing generally include the following steps: Step 1: Start the low-pressure water pump. Step 2: Low-pressure water washing Aim the nozzle at the inner wall of the empty barrel and start low-pressure water washing. Parameter setting: The water pressure is usually between 3-5bar, which is enough to remove loose sediment and dirt, but will not damage the inner wall of the empty barrel. Water flow rate: adjusted according to the type of nozzle and the size of the empty barrel, usually 15-20L / min. Start from the top of the empty bucket and slowly move the nozzle downwards to ensure even coverage of the entire inner wall. For corners and hard-to-reach areas, you can adjust the nozzle angle or use a different nozzle, and move the nozzle up and down. Step 3: Monitor and adjust During the cleaning process, monitor the cleaning effect and adjust the water pressure and nozzle distance if necessary. Make sure the water flow does not cause damage to the empty bucket.

[0031] In this embodiment, the medium-pressure alkaline cleaning step includes: checking the three-head water jet nozzle assembly to ensure that the three-head water jet nozzle, rotating arm and drive motor and other components are intact. Prepare an alkaline cleaning agent solution of appropriate concentration and deliver it to the feed port of the medium-pressure pump. Start the drive motor to start the rotating arm, and move the three-head water jet nozzle to the bottom of the empty barrel mouth, with the nozzle aligned with the center of the empty barrel for uniform cleaning. Turn on the medium-pressure pump and spray the prepared alkaline cleaning agent solution into the empty barrel through the three-head water jet nozzle. Driven by the rotating arm, the empty barrel rotates at a predetermined speed, and the nozzle sprays a medium-pressure alkaline cleaning agent solution. The design of the nozzle ensures that the alkaline cleaning agent can cover all parts of the barrel wall, and during the flushing process, the nozzle moves up and down so that the cleaning agent sprayed by the nozzle can reach all corners of the empty barrel. Keep spraying for a while to allow the alkaline cleaning agent to fully contact the stubborn stains, impurities and foreign objects in the barrel to soften the dirt. According to the condition of the dirt in the barrel, the data is transmitted to the control system to adjust the parameter data of the spray pressure and rotation speed of the nozzle for deep alkaline cleaning.

[0032] In this embodiment, the three-head water jet nozzle assembly in the high-pressure water washing step includes a three-head water jet nozzle, and the empty barrel of bottled water keeps rotating to rinse out the stubborn stains, impurities, and foreign matter in the empty barrel, and brush off the cleaning agent and dirt remaining after alkali washing. The high-pressure water washing step includes step 1: starting the high-pressure water pump. Step 2: adjusting the parameters, water pressure, according to the type of dirt and the material of the empty barrel, adjust the water pressure to about 60bar. Water flow rate, adjust the water flow rate to 15-20L / min to obtain sufficient cleaning force. Step 3: high-pressure water washing, after aligning the three-head water jet nozzle with the empty barrel of bottled water, start the equipment to rotate the empty barrel of bottled water at an appropriate speed. Turn on the high-pressure water pump and start high-pressure water washing. Starting from the neck of the empty barrel, slowly move the nozzle upward, and reciprocate up and down to ensure that the high-pressure water flow evenly covers the inner wall of the empty barrel. The design of the three-head water jet nozzle allows the water flow to spray at multiple angles, thereby more effectively brushing off impurities, foreign matter and cleaning agents and dirt remaining after alkali washing. Step 4: Monitor and adjust. During the cleaning process, monitor the cleaning effect and, if necessary, adjust the water pressure, flushing time, and rotation speed of the empty barrel of water.

[0033] In this embodiment, the low-pressure disinfection step includes: moving the pre-cleaned empty barrel of bottled water to the nozzle of the disinfection system, and spraying the diluted disinfectant onto the inner wall of the empty barrel through the nozzle. The low-pressure spraying can ensure that the disinfectant evenly covers the barrel wall, while avoiding splashing caused by high-pressure spraying. By increasing the action time of the disinfectant on the inner wall of the barrel, the disinfectant can more effectively kill bacteria, viruses and other microorganisms. The contact time of the disinfectant is crucial to the disinfection effect. Therefore, appropriately extending the length of the chain path is the key to improving the disinfection effect. After rinsing, the empty barrel is removed from the disinfection system for subsequent inspection or use. Use disinfectant to perform low-pressure disinfection on the inner wall of the empty barrel of bottled water, and by extending the length of the rear section of the chain path as much as possible, increase the operation time of the empty barrel, thereby increasing the action time of the disinfectant on the inner wall of the barrel and enhancing the disinfection effect.

[0034] In this embodiment, the three-head water jet nozzle includes a nozzle body, a nozzle, a lifting chain and a drive motor. The three-head water jet nozzle body is designed, and the nozzle body includes three independent nozzles. These nozzles are arranged at a certain angle to cover a wider area while providing concentrated water flow. The material is usually made of high-pressure resistant and wear-resistant metal materials to withstand the impact of high-pressure water flow. The nozzle material is usually made of cemented carbide or other wear-resistant and corrosion-resistant materials to extend the service life. The nozzle shape is designed to be a slit or a cone to produce water flows of different shapes, which are suitable for different cleaning tasks. The lifting chain connects the nozzle bracket and the drive motor, allowing the nozzle bracket to drive the nozzle to move up and down on the fixed axis. The lifting chain and bracket material are usually made of metal to ensure strength and stability. Drive motor type: It can be an AC motor or a DC motor to provide lifting power.

[0035] In this embodiment, the device includes an empty barrel pressing module, a rotating arm and a driving motor. The empty barrel pressing module is connected to the rotating arm and driven by the driving motor to drive the empty barrel of bottled water to rotate. Barrel pressing module: used to fix the empty barrel to ensure that it remains stable during the cleaning process. Rotating shaft: connected to the empty barrel so that it can rotate around the axis. Motor: drives the rotating shaft to make the empty barrel rotate. Press the barrel pressing module onto the empty barrel and fix it, ensure that the three-head water jet nozzle is aligned with the entrance of the empty barrel, start the motor, and make the rotating shaft drive the empty barrel to start rotating. At the same time, turn on the three-head water jet nozzle, so that the water flow is sprayed to the inner wall of the rotating empty barrel at a certain pressure and angle. The water flow of the three-head water jet nozzle will form a uniform coverage on the inner wall of the empty barrel to clean the dirt in the barrel. Since the empty barrel is rotating, the water flow of the nozzle can cover every corner of the barrel to ensure that there is no dead angle in the cleaning. The rotation speed and the spray pressure of the nozzle need to be adjusted according to the size of the barrel and the degree of pollution. After the cleaning is completed, turn off the motor and the nozzle, and the empty barrel stops rotating.

[0036] In this embodiment, the detailed steps of the nozzle operation include: Install the nozzle: Install the three-head water jet nozzle on the nozzle bracket, and ensure that the nozzle is firmly fixed. The bracket is connected to the drive motor through a chain: Connect the chain to the output shaft of the drive motor. If a gear box is used, ensure that the gear box is properly installed and lubricated. Electrical connection: Connect the drive motor to the power supply and ensure that all electrical connections are safe and reliable.

[0037] Control system: Install a control system so that the operator can start and stop the drive motor, as well as adjust the rotation speed and direction. Operation steps: Start the drive motor, the rotating arm begins to drive the nozzle to rotate, turn on the high-pressure water supply, and the water flows through the nozzle of the three-head water jet nozzle to perform the cleaning operation. The operator can use the control system to adjust the water flow, pressure, time and the up and down position of the nozzle to adapt to different cleaning needs. Safety measures: Ensure that all operations are carried out under safe conditions, including wearing appropriate personal protective equipment and ensuring safe isolation of the work area. With this connection and operation method, the three-head water jet nozzle can work efficiently during the cleaning and disinfection process of barreled water, empty barrels or other containers, providing uniform and thorough cleaning results.

[0038] In this embodiment, the empty barrel reaches the secondary appearance inspection station through the transmission system. The high-resolution camera captures the image of the empty barrel under appropriate lighting conditions, usually including multiple angles to ensure comprehensive inspection. The collected image is transmitted to the image processing unit for a series of processing, such as denoising, contrast enhancement, edge detection, etc. The image is analyzed using an image recognition algorithm to identify the uncleaned area or residual stains. The detected uncleaned area is compared with the preset cleaning standard. If the detected uncleaned area exceeds the range allowed by the standard, it is judged as unqualified. After receiving the unqualified signal, the control system sends an instruction to the transmission system. The transmission system re-dispatches the unqualified empty barrel back to the flushing area according to the instruction of the control system. The unqualified empty barrel is located at a specific flushing position. According to the specific situation of the uncleaned area, the control system adjusts the flushing parameters, such as increasing the flushing pressure, extending the flushing time, etc. The empty barrel is rinsed again in a targeted manner to remove the uncleaned area. After the empty barrel is rinsed again, it will return to the secondary appearance inspection station for repeated secondary appearance inspection to ensure that all uncleaned areas have been effectively removed.

[0039] In some embodiments, a disinfection characteristic database is also set in the control system to automatically adjust the cleaning and disinfection parameters to adapt to the working mode of different disinfection requirements. The control system also includes an automatic control start-stop drive motor and water pump to control the rotation of the nozzle and the water jet. The disinfection parameter characteristic database is used to store different types of disinfection parameter data, such as automatically adjusting the cleaning and disinfection parameters, and automatically adjusting the parameters in the cleaning and disinfection process, such as water pressure, flow, nozzle angle, etc. according to the information in the characteristic database. Parameter adjustment is intended to ensure that the cleaning and disinfection process can achieve the best cleaning effect. Automatically control the start and stop of the drive motor and water pump to control the start and stop of the drive motor and water pump to achieve the rotation of the nozzle and the spray of water. Real-time control of the motor and pump is achieved through sensors and actuators to ensure the accuracy and consistency of the cleaning and disinfection process. In actual operation, the database stores preset values ​​of various disinfection parameters, including but not limited to water pressure, flow, nozzle up and down position, cleaning time, disinfectant concentration, etc. Physical parameters such as water pressure, flow, temperature, etc. Chemical parameters such as disinfectant type and concentration, etc. Time parameters such as cleaning cycle, disinfection time, etc. The database supports adding, editing, deleting and querying parameter data. Parameters can be optimized based on actual cleaning results and historical data. Automatically adjust cleaning and disinfection parameters. The system automatically selects appropriate parameter configurations by obtaining real-time data through sensors. Based on the information in the database, the system automatically adjusts parameters such as water pressure, flow, and nozzle angle to adapt to different working methods. The system has learning capabilities and can adjust parameters based on cleaning effect feedback to achieve self-optimization. Automatically control the start and stop of drive motors and water pumps. The system automatically starts and stops drive motors and water pumps according to the needs of the cleaning and disinfection processes. The operating status of motors and pumps is monitored in real time through sensors to ensure that the equipment works within a safe range. When an abnormal situation is detected, the system can automatically stop the motor and pump and sound an alarm.

[0040] In some embodiments, the process of matching disinfection parameters in the control system involves multiple steps to ensure that the cleaning and disinfection parameters can adapt to different types of cleaning and disinfection requirements. The performance data of disinfection is mapped with the cleaning and disinfection parameters to form a reference table for parameter adjustment. Real-time monitoring, the control system monitors the key parameters in the cleaning and disinfection process in real time, such as water pressure, flow, temperature, etc. According to the real-time monitoring data, the control system automatically matches the parameter adjustment reference table in the characteristic database to calculate the optimal cleaning and disinfection parameters. The control system adjusts the relevant parameters of the cleaning and disinfection empty barrel through the actuator, such as the speed of the water pump, the upper and lower positions of the nozzles, the flow rate of the disinfectant, etc. A feedback mechanism is established.
