Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to an analysis and control method and system based on oral solution monitoring data. Background Technology

[0002] The overall production process of oral solutions typically employs an assembly line operation to ensure efficiency, precision, and standardization at every stage. The first stage is bottle preparation, which includes cleaning, sterilizing, and pre-inspecting the bottles to ensure they are free of defects and meet filling requirements. Next comes the cap preparation stage, where caps undergo quality inspection and pretreatment to ensure smooth capping in subsequent steps. The next stage is filling, where the oral solution is accurately filled into the prepared bottles under strict dosage control and aseptic conditions. Finally, the automatic capping and packaging stage begins.

[0003] Currently, in the production of oral solutions, capping is a key process, and its quality directly affects the product's sealing and safety. Traditional automatic capping equipment mainly relies on preset torque and force parameters to complete the capping. However, due to multiple factors during the packaging process, such as cap flatness, deformation, damage, and overall height, setting a single parameter cannot fully reflect the actual packaging quality, easily leading to uneven product quality and the production of defective products. Furthermore, traditional processes lack a real-time feedback mechanism, making it difficult to adjust and control abnormalities that occur during packaging in a timely manner, thus affecting overall production efficiency and product consistency.

Figure 2 This is a structural framework diagram of an analysis and control system based on oral solution monitoring data according to the present invention. Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1 Please see Figure 1 The present invention provides an analysis and control method based on oral solution monitoring data, comprising: Step 1: Cap the positioned oral solution using the torque and force preset by the automatic capping machine; It should be noted that before the automatic capping machine packages the oral solution, it generally goes through bottle preparation, cap preparation, and filling processes. After these preliminary steps are completed, the final process is usually to use the automatic capping machine to seal and package the oral solution. This integrated process is generally carried out in a complete packaging process in the form of an assembly line. Step 2: After the oral solution is capped using an automatic capping machine, several capping packaging evaluations are conducted. The overall capping packaging evaluation value is determined by combining the results of these evaluations. The aforementioned assessments of screw cap packaging include cap flatness assessment, cap deformation assessment, and overall cap height monitoring assessment. The specific content of conducting several evaluations of screw-cap packaging and determining the overall evaluation value of screw-cap packaging by combining the results of these evaluations includes: The specific method for assessing the flatness of the bottle cap is as follows: AS1: Establish a reference plane on the horizontal plane where the bottle cap's flat end is located, and set a height of [missing information] above the reference plane. Establish the first calibration plane at the location; AS2: Next, determine the area of ​​the flat end of the bottle cap, and confirm its detection surface based on the area of ​​the flat end of the bottle cap. Generally, the bottle cap is round, and the confirmed detection surface is round. Then, draw c vertical line segments from each area unit of the calibration surface to reach the detection surface. AS3: Get the height of each vertical line segment, denoted as Gi, where 1 ≤ i ≤ n, and n is the total number of vertical line segments. The area of ​​the flat end of the bottle cap; Next, calculate the absolute Hi of Gi and height d: Compare Hi with the preset value Y1 to identify abnormal vertical line segments: If Hi > Y1, mark the vertical line segment as an abnormal vertical line segment; otherwise, do not perform any processing. Based on the above judgment, statistics were then compiled. The total number of all abnormal vertical segments in the vertical line segment, and marked as Sz; The preset value Y1 is the allowable error value, which is set by professional staff. AS4: Obtain Sz, calculate the ratio of Sz to n, and obtain the bottle cap flatness evaluation value P1: ; The specific method for evaluating bottle cap deformation is as follows: BS1: Obtain the height D of the bottle cap, and establish a second calibration surface at a height D below the reference surface; BS2: Identify whether the second calibration surface intersects with one end of the bottle cap: If there is no contact or intersection, it indicates that the bottle cap was not properly capped during the automatic capping machine's packaging process, or that the bottle cap itself has defects such as not meeting the standards. In this case, the bottle cap deformation assessment value P2 is determined: P2=R; where R is a preset value, specifically set by professional staff. In this case, the bottle cap deformation is most obvious, and the obtained bottle cap deformation assessment value P2 is sufficient to cause this capping result to be unqualified in the subsequent result judgment. If there is contact or intersection, proceed with the following steps to determine the cap deformation assessment value: BS21: Obtain the intersection line between the second calibration surface and one end of the bottle cap: Identify whether the intersection line is a closed shape. If the shape is not closed, in this embodiment it is an arc-shaped line segment: obtain and measure the length of the intersecting line, denoted as L1, and at the same time obtain the circumference Ls of the bottle cap. Determine the bottle cap deformation evaluation value P2 using the following formula: ; It should be noted that the bottle caps for oral solutions of the same standard are all designed in a uniform manner, so the circumference and radius of the bottle cap are a preset fixed value that can be measured in advance. If the shape is closed, in this embodiment it is either circular or arc-shaped: Identify the integrity of the closed shape, and determine the bottle cap deformation assessment value based on the integrity of the closed shape: The method for determining the bottle cap deformation assessment value based on the integrity of the identified graphic is as follows: Obtain a circle intersecting the outer surface of the oral solution bottle on the second calibration surface, denoted as the reference circle, and display it on the second calibration surface. Determine the center O of the reference circle, and simultaneously obtain the circular radius of the bottle cap. ; Starting from the center O, extend a line towards the closed figure at every 15-degree rotation, until the extension reaches the boundary of the closed figure. Obtain the length of the extension, denoted as Xj. Calculate the absolute value of Xj and the radius r, denoted as Bj. ,in Next, the bottle cap deformation assessment value P2 is calculated using the following formula: in, Represented as The largest With radius The absolute value; The specific method for monitoring and evaluating the overall height of the bottle cap is as follows: The overall height of the oral solution after being capped by the automatic capping machine is recorded as h1; calculate With preset threshold The absolute value determines the overall height of the bottle cap for monitoring and evaluation (P3). The preset threshold HB is the allowable height error value. These are weighting coefficients, specifically determined by professional staff. Based on the aforementioned determined bottle cap flatness assessment value 1. Bottle cap deformation assessment value 2. Overall height monitoring and evaluation of bottle caps 3. Based on the combined results of the three assessments, the overall capping packaging assessment value ZP is determined using the following weighted formula: in, , These are weighting coefficients, specifically determined by professional staff based on experience. After the capping packaging is completed, this step involves multi-dimensional and detailed inspection of the cap's flatness, deformation, and overall height. Quantitative analysis is conducted using methods such as vertical line segment detection, calibration surface establishment, and graphic integrity recognition. After synthesizing all the inspection data, a weighted calculation is used to determine the overall packaging evaluation value. This not only comprehensively and objectively reflects the actual effect of the capping process but also promptly identifies and locates potential anomalies, ensuring that product quality meets stringent standard requirements, thereby improving the inspection accuracy and stability of the entire production process. Step 3: Based on the overall capping packaging evaluation value, classify the capping packaging inspection into three categories: standard qualified, basically qualified, and basically qualified; and take corresponding follow-up inspection measures based on the classification results. The capping packaging is classified according to the overall assessment value into three categories: standard qualified, basically qualified, and unqualified. Based on the classification results, the specific methods for taking corresponding follow-up inspection measures are as follows: Obtain the overall capping packaging evaluation value ZP, and perform the following judgments to classify the capping packaging inspection: like It is classified as a standard qualified category for screw-cap packaging and is directly judged as qualified without the need for subsequent manual inspection. like The products are classified as basically qualified for screw-cap packaging. The screw-cap oral solution bottles are marked with a yellow mark and require subsequent manual inspection to pass the inspection. like The items were classified as non-compliant due to screw-cap packaging. Oral solution bottles with screw-cap packaging were marked in red and automatically rejected in the future. K1 and K2 are preset values, which will be determined by professional staff, and K2>K1; Based on the aforementioned comprehensive evaluation values, this step categorizes the capping packaging results into three types: standard qualified, basically qualified, and unqualified. Different colors are used to mark the products (e.g., yellow indicates manual re-inspection, red indicates automatic rejection) to achieve rapid differentiation and processing. This not only significantly improves testing efficiency and reduces the burden of manual inspection, but also allows for immediate response to abnormal products, effectively preventing unqualified products from entering the market and ensuring the overall quality and safety of the final product. Furthermore, it provides a clear reference for subsequent process adjustments. Step 4: Based on the results of capping packaging inspection and classification, after each capping packaging inspection and classification, obtain the previous... The results of the previous capping packaging inspection and classification were analyzed. The results of the inspection and classification of screw cap packaging were used to determine the defect rate of screw cap packaging in this inspection and classification. Based on the results of capping packaging inspection and classification, the previous data is acquired in real time after each capping packaging inspection and classification. The results of the previous capping packaging inspection and classification were analyzed. The specific method for determining the defect rate of screw-cap packaging in this inspection and classification process is as follows: Obtain the classification results of the first m capping packaging inspections: If the classification result of the vth screw cap packaging inspection is that the screw cap packaging meets the standard, then assign a value of 0; If the classification result of the vth screw-cap packaging inspection is basically qualified, then assign a value of 0.5; If the classification result of the vth screw cap packaging inspection is screw cap packaging non-conforming, then assign the value 1; Where m is a preset value, specifically set by professional personnel; in this embodiment, m is 30, and ; Next, the sum of the values ​​assigned in the previous m assignments and the values ​​assigned in this completed capping packaging inspection and classification is recorded as follows: And through the formula The defect rate of the screw cap packaging was determined in this inspection and classification. This step involves acquiring previous data in real time. The results of the current and next capping packaging inspections are compared and classified. Preset values ​​are assigned to different categories for statistical processing to calculate the current capping packaging defect rate. In this way, not only can quality fluctuations in the production process be dynamically monitored, but also the equipment operating status and process stability can be reflected through quantitative data. This provides scientific data support for timely detection of production anomalies and the formulation of improvement plans, effectively ensuring the consistency and stability of products. Step 5: Based on the defect rate of each completed capping packaging inspection and classification, establish a defect rate curve. Based on the analysis results of the defect rate curve, take corresponding actions to stop the automatic capping machine, fine-tune the torque and torque, and maintain operation. Example 2 In this embodiment, based on Embodiment 1, but differing from Embodiment 1 in that step five is further explained: The specific methods for establishing a defect rate curve based on the defect rate of each completed capping packaging inspection and classification, and for making corresponding automatic capping machine shutdown, torque fine-tuning, and operation maintenance actions based on the defect rate curve analysis results are as follows: CS1: Create a defect rate curve, with the horizontal axis representing time and the vertical axis representing the defect rate value. CS2: Real-time acquisition of the latest defect rate value from the defect rate curve, and recording it as... ,Will Compare with thresholds Q1 and Q2: like At that time, identify the first Do all defect rate values ​​exceed Q1? (When the first...) If all defect rates exceed Q1, the automatic capping machine will be stopped; otherwise, the automatic capping machine's fine-tuning torque and torque settings will be adjusted. The specific settings are determined by professional staff based on their experience. like At the same time, the automatic capping machine is fine-tuned in terms of torque and torque. like At that time, the automatic capping machine was kept running. It should be noted that the fine-tuning torque of the automatic capping machine is handled by experienced personnel or programming engineers who fine-tune the torque and torque according to the pre-set program before the process. In this step, a curve is constructed based on the defect rate data obtained from each inspection. By monitoring the change trend of the defect rate in real time, it is automatically determined whether it exceeds the preset threshold, and corresponding feedback control measures are triggered accordingly, such as automatic shutdown, fine adjustment of torque and force, or continued normal operation. This not only enables timely response to abnormal fluctuations in the production process, but also allows for continuous self-adjustment and optimization during equipment operation, thereby significantly reducing the defect rate and improving the automation level and economic benefits of the entire production line.

The packaging evaluation module is used to perform several evaluations of screw-cap packaging, and to determine the overall evaluation value of screw-cap packaging by combining the results of these evaluations. The aforementioned assessments of screw cap packaging include cap flatness assessment, cap deformation assessment, and overall cap height monitoring assessment. The inspection and classification module is used to classify screw cap packaging according to the overall evaluation value, into three categories: standard qualified screw cap packaging, basically qualified screw cap packaging, and basically qualified screw cap packaging. Based on the classification results, corresponding manual inspection and automatic rejection operations are carried out.

9. An analysis and control system based on oral solution monitoring data, implemented in any one of claims 1-8, characterized in that, include: The preset capping module is used by the automatic capping machine to cap and package the positioned oral solutions using pre-set torque and force. The packaging evaluation module is used to perform several evaluations of screw-cap packaging, and to determine the overall evaluation value of screw-cap packaging by combining the results of these evaluations. The aforementioned assessments of screw cap packaging include cap flatness assessment, cap deformation assessment, and overall cap height monitoring assessment. The inspection and classification module is used to classify screw cap packaging inspection based on the overall screw cap packaging evaluation value, into three categories: standard qualified screw cap packaging, basically qualified screw cap packaging, and unqualified screw cap packaging. Based on the classification results, corresponding manual checks for over-inspection and automatic rejection operations are carried out. The defect analysis module is used to obtain the previous results in real time after each capping packaging inspection and classification, based on the results of the capping packaging inspection and classification. The results of the previous capping packaging inspection and classification were analyzed. The results of the inspection and classification of screw cap packaging were used to determine the defect rate of screw cap packaging in this inspection and classification. The feedback control module is used to establish a defect rate curve based on the defect rate of each completed capping packaging inspection and classification. Based on the analysis results of the defect rate curve, the module will take corresponding actions to stop the automatic capping machine, fine-tune the torque, or maintain operation.
