Description

Technical Field

[0001] The present invention relates to the technical field of food processing, and in particular to a grading and screening device and method for intelligently adjusting sauerkraut. Background Art

[0002] Grading and screening are crucial steps in sauerkraut processing. Traditional grading and screening methods, which mostly rely on manual labor, are inefficient and inaccurate. Furthermore, as market demands for sauerkraut quality increase, so too do weight-based grading requirements.

[0003] The existing use of automated mechanical equipment to intelligently sort, transport and store sauerkraut can improve the processing efficiency of sauerkraut and thus enable large-scale processing of sauerkraut.

[0004] However, the weight of sauerkraut varies greatly. When mechanically grading and screening sauerkraut, it is difficult to grade and screen sauerkraut of different weights. As a result, when packaging, the same amount of water is filled in, which affects the shelf life and taste of the sauerkraut. Summary of the Invention

[0005] The purpose of the present invention is to provide a grading and screening device and method with intelligent adjustment of sauerkraut, which solves the problem that it is difficult to grade and screen sauerkraut of different weights during mechanized grading and screening of sauerkraut, and then fills the same amount of water during packaging, which affects the shelf life and taste of the sauerkraut.

[0006] To achieve the above object, the present invention provides a sauerkraut intelligently regulated grading and screening device and method, comprising the following steps:

[0007] The sauerkraut is transported to the grading and screening mechanism through the conveying device and evenly distributed on the screen;

[0008] The weight sensor detects the weight of the sauerkraut on each layer of the screen in real time and transmits the data to the intelligent control system;

[0009] The intelligent control system determines the weight class of the sauerkraut based on six preset weight classification standards;

[0010] According to the judgment results, the intelligent control system controls the conveying device and the grading and screening mechanism to transport the sauerkraut to the corresponding collection device;

[0011] The collecting device transports the graded and screened sauerkraut to the packaging station, where it packages the sauerkraut in six different weight grades and pours the corresponding volume of water into it.

[0012] Among them, in the step of “transporting the sauerkraut to a grading and screening mechanism through a conveying device and evenly distributing the sauerkraut on the screen”, the method includes the following steps:

[0013] Put the sauerkraut into the cleaning tank and stir and clean it;

[0014] The robotic gripper scoops out the sauerkraut and places it on the draining platform for draining. The vibration of the draining platform removes impurities and large foreign objects mixed in the sauerkraut.

[0015] The sauerkraut is continuously placed on the conveying equipment, and the sauerkraut on the conveyor belt is evenly distributed through the vibrating feeder and transported to the grading and screening station;

[0016] Monitor the accumulation of sauerkraut during transport to the grading and screening station, and control the robotic arm to push the accumulated sauerkraut onto the screen of the grading and screening station

[0017] Among them, in the step of “monitoring the accumulation of sauerkraut when it is transported to the grading and screening station, and controlling the robotic arm to push the accumulated sauerkraut onto the screen of the grading and screening station”, the method includes the following steps:

[0018] Install cameras and infrared sensors near the transition between the conveying equipment and the grading and screening stations to monitor the accumulation of sauerkraut during transportation in real time;

[0019] Connect the monitoring equipment to the monitoring system to ensure real-time data transmission, and set accumulation judgment thresholds in the monitoring system, including accumulation height, area, and volume;

[0020] Configure the alarm function. When the monitoring system detects that the accumulation situation reaches the threshold, it will automatically issue an alarm.

[0021] The control program receives the alarm signal from the monitoring system, determines the stacking location, and controls the robotic arm to move to the sauerkraut stacking location, starts the monitoring system and the robotic arm, and the robotic arm uses a pushing tool to push sauerkraut of various shapes and sizes onto the screen of the grading and screening station.

[0022] Among them, in the process of “the weight sensor detects the weight of the sauerkraut on each layer of the screen in real time and transmits the data to the intelligent control system”, the process includes the following steps:

[0023] A weight sensor is installed at a suitable position below each layer of screen. The sensor measures the weight of the sauerkraut on the screen. After installation, the weight sensor is calibrated.

[0024] The weight sensor detects the weight of the sauerkraut on the screen in real time and transmits the detected data to the intelligent control system. During the data collection process, a filtering algorithm is used to process the raw data to remove noise and interference;

[0025] The communication protocol is used to realize data transmission between the weight sensor and the intelligent control system. The intelligent control system receives the data transmitted by the weight sensor and performs verification;

[0026] The intelligent control system stores the received data in a database for analysis. Based on the analysis results, the intelligent control system generates corresponding control instructions to adjust the speed of the conveying device and control the action of the grading and screening mechanism.

[0027] In the step of "the intelligent control system determines the weight class of the sauerkraut according to a preset weight classification standard", the method further includes the following steps:

[0028] According to production needs and quality requirements, six weight grading standards for sauerkraut are determined: less than 200g, 201-250g, 251-300g, 300-350g, 351-400g, and more than 400g;

[0029] The intelligent control system receives real-time data from the weight sensor, i.e., the weight of the sauerkraut on each layer of the screen, and pre-processes the received data, including data cleaning, format conversion, and outlier processing;

[0030] The pre-processed data is compared and matched with the preset weight classification standards. Based on the matching results, the intelligent control system determines the weight class to which the sauerkraut belongs.

[0031] The intelligent control system outputs the judgment result to the execution module of the intelligent control system.

[0032] Among them, in the step “according to the judgment result, the intelligent control system controls the operation of the conveying device and the grading and screening mechanism to convey the sauerkraut to the corresponding collection device”, the method includes the following steps:

[0033] The system uses the sauerkraut weight classification results obtained by the execution module to determine the target collection device to which each sauerkraut should be transported;

[0034] The intelligent control system generates corresponding control signals based on the analytical judgment results. The intelligent control system adjusts the speed of the conveying device, and the sauerkraut is smoothly and continuously conveyed to the grading and screening mechanism.

[0035] The intelligent control system activates the grading and screening mechanism, causing it to act according to the control signal. The grading and screening mechanism adjusts the vibration frequency of the screen and opens or closes specific screening channels.

[0036] After the sauerkraut is graded and screened, the intelligent control system adjusts the path of the conveying device so that the sauerkraut falls accurately into the corresponding collection device.

[0037] The method of "the collecting device transports the graded and screened sauerkraut to the packaging station, packages the sauerkraut of six different weight grades, and pours corresponding volumes of water" includes the following steps:

[0038] The intelligent control system plans the conveying path from the collection device to the packaging station;

[0039] Prepare packaging materials of different specifications and materials according to the weight level of sauerkraut;

[0040] The sauerkraut is conveyed into the packaging material and sealed by the sealing machine and labeled by the labeling machine;

[0041] The intelligent control system controls the water injection machine to inject a certain volume of water into the package according to the weight level and packaging requirements of the sauerkraut;

[0042] Check the appearance, weight and seal of the packaged sauerkraut.

[0055] A grading and screening method for intelligently adjusting sauerkraut comprises the following steps:

[0056] S1: transporting the sauerkraut to the grading and screening mechanism through a conveying device and evenly distributing it on the screen;

[0057] S11: putting the sauerkraut into a washing tank and stirring and washing the sauerkraut;

[0058] S12: The robotic arm gripper scoops out the sauerkraut and places it on a draining platform for draining. The platform vibrates to remove impurities and large foreign objects mixed in the sauerkraut.

[0059] S13: Continuously placing the sauerkraut on the conveyor, evenly distributing the sauerkraut on the conveyor belt through a vibrating feeder, and transferring the sauerkraut to a grading and screening station;

[0060] S14: Monitor the accumulation of sauerkraut being transported to the grading and screening station, and control the robotic arm to push the accumulated sauerkraut onto the screen of the grading and screening station:

[0061] S141: Install cameras and infrared sensors near the transition between the conveying equipment and the grading and screening stations to monitor the accumulation of sauerkraut during transportation in real time;

[0062] S142: Connect the monitoring equipment to the monitoring system to ensure real-time data transmission, and set accumulation judgment thresholds in the monitoring system. The thresholds include accumulation height, area, and volume.

[0064] S144: The control program receives an alarm signal from the monitoring system, determines the stacking position, and controls the robotic arm to move to the sauerkraut stacking position, starts the monitoring system and the robotic arm, and the robotic arm pushes the sauerkraut of various shapes and sizes onto the screen of the grading and screening station through a pushing tool.

[0065] In this embodiment:

[0066] Sauerkraut pretreatment: Ensure that the sauerkraut is in a suitable state before entering the conveying device to facilitate subsequent uniform distribution and grading screening. By checking the state of the sauerkraut, impurities, large foreign objects or unqualified products are removed; as needed, the sauerkraut is properly washed, drained or cut.

[0067] Start the conveyor: transport the pre-treated sauerkraut from the storage or processing area to the grading and screening mechanism; check the operating status of the conveyor to ensure it is in good working condition; adjust the speed and direction of the conveyor according to production needs; start the conveyor and prepare to receive the pre-treated sauerkraut.

[0068] Sauerkraut loading: Place the sauerkraut onto the conveyor continuously and stably. Use appropriate loading equipment (such as a vibrating feeder, screw conveyor, etc.) to feed the sauerkraut onto the conveyor. Control the loading speed to ensure the sauerkraut maintains proper spacing and distribution on the conveyor.

[0069] Adjustments during conveying: Fine-tune the distribution of the sauerkraut during conveying to ensure it is evenly distributed on the screen; observe the distribution of the sauerkraut on the conveyor and, if necessary, adjust the loading speed or the angle of the conveyor; use auxiliary means such as vibration, stirring, or airflow to help disperse the sauerkraut more evenly during conveying.

[0070] The sauerkraut enters the grading and screening mechanism: the sauerkraut is smoothly transferred from the conveying device to the screen of the grading and screening mechanism; the connection part between the conveying device and the grading and screening mechanism is adjusted to ensure that the sauerkraut can slide smoothly onto the screen; the process of the sauerkraut entering the screen is monitored, and if there is blockage or accumulation, the speed or angle of the conveying device is adjusted in time.

[0071] Even distribution on the sieve: Ensure that the sauerkraut is evenly distributed on the sieve so that the weight sensor can accurately measure the weight of the sauerkraut on each layer of the sieve; observe the distribution of the sauerkraut on the sieve and make slight adjustments using manual or mechanical means if necessary; ensure that the vibration or stirring device of the sieve (if any) is in proper working condition to promote even distribution of the sauerkraut.

[0072] Monitoring and feedback: Real-time monitoring of the status of sauerkraut during transportation, grading and screening to ensure smooth operations; use cameras, sensors and other monitoring equipment to observe the status and distribution of sauerkraut in real time; if any abnormal situation is found (such as blockage, accumulation, uneven weight distribution, etc.), timely alarm is issued and corresponding corrective measures are taken.

[0073] S2: The weight sensor detects the weight of the sauerkraut on each layer of the screen in real time and transmits the data to the intelligent control system:

[0074] S21: Install a weight sensor at a suitable position below each layer of screen. The sensor measures the weight of the sauerkraut on the screen. After installation, calibrate the weight sensor.

[0075] S22: The weight sensor detects the weight of the pickled cabbage on the screen in real time and transmits the detected data to the intelligent control system. During the data collection process, a filtering algorithm is used to process the raw data to remove noise and interference;

[0076] S23: Using a communication protocol to realize data transmission between the weight sensor and the intelligent control system, the intelligent control system receives the data transmitted by the weight sensor and performs verification;

[0077] S24: The intelligent control system stores the received data in a database for analysis. Based on the analysis results, the intelligent control system generates corresponding control instructions to adjust the speed of the conveying device and control the action of the grading and screening mechanism.

[0078] In this embodiment, to accurately monitor and manage weight information during the sauerkraut grading and screening process, we employ the following comprehensive measures: First, weight sensors are installed appropriately beneath each layer of screens. These sensors are specifically designed to measure the real-time weight of the sauerkraut accumulated on the screens. Following installation, all weight sensors undergo rigorous calibration to ensure accurate measurement data. The weight sensors then operate continuously, monitoring the weight changes of the sauerkraut on the screens in real time. This valuable data is then processed using advanced filtering algorithms. This process effectively removes noise and interference from the raw data, improving its accuracy and reliability. To ensure efficient communication between the sensors and the intelligent control system, a specific communication protocol is employed to ensure smooth and error-free data transmission. Once the intelligent control system receives the verified weight data, it immediately stores it in a database for further analysis. Based on this data analysis, the intelligent control system intelligently generates corresponding control instructions, such as adjusting the conveyor speed or precisely controlling the operation of the grading and screening mechanism, thereby enabling refined management of the sauerkraut grading and screening process.

[0079] S3: The intelligent control system determines the weight class of the sauerkraut according to the six preset weight classification standards;

[0080] S31: Based on production needs and quality requirements, six weight grading standards for sauerkraut are determined: less than 200g, 201-250g, 251-300g, 300-350g, 351-400g, and greater than 400g;

[0081] S32: The intelligent control system receives real-time data from the weight sensor, i.e., the weight of the sauerkraut on each layer of the screen, and pre-processes the received data, including data cleaning, format conversion, and outlier processing;

[0083] S34: The intelligent control system outputs the judgment result to the execution module of the intelligent control system.

[0084] In this embodiment:

[0085] 1. Establish weight grading standards for sauerkraut

[0086] Based on production needs and quality requirements, we have determined six weight grading standards for sauerkraut, as follows:
