Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine production technology, and in particular to a method and system for venting exhaust from a traditional Chinese medicine liquid packaging bag. Background Technology

[0002] Traditional Chinese medicine liquid packaging refers to the containers and materials used to package traditional Chinese medicine liquid products. This form of packaging is crucial for the safe and hygienic storage and quality protection of traditional Chinese medicine liquids. Therefore, the design and application of traditional Chinese medicine liquid packaging bags play an important role in the modern traditional Chinese medicine industry.

[0003] After the traditional Chinese medicine is produced, the liquid medicine is filled into packaging bags using filling equipment, and then the packaging bags are sealed using plastic sealing equipment to ensure that the liquid medicine is not affected by external factors during storage and transportation.

[0004] In the aforementioned technologies, although the packaging bags are sealed during the production of traditional Chinese medicine, some air still remains inside. The presence of this air may affect the efficacy and shelf life of the traditional Chinese medicine, and there is still room for improvement. Summary of the Invention

[0005] To reduce the possibility that the efficacy and shelf life of traditional Chinese medicine are affected by air, this invention provides a method and system for venting air from packaging bags containing traditional Chinese medicine liquid.

[0006] In a first aspect, the present invention provides a method for venting air from a packaging bag for traditional Chinese medicine liquid, employing the following technical solution: A method for venting air from a traditional Chinese medicine liquid packaging bag, comprising: Obtain the filling status of the medicine solution; When the liquid filling state matches the preset completed filling state, control the through-beam devices on both sides of the packaging bag to move upward from the preset original position, and obtain the through-beam status and through-beam movement distance of the through-beam devices in real time. When the photoelectric state is consistent with the preset successful reception state, the exhaust point is determined based on the current photoelectric movement distance and the original position, and the exhaust movement distance is calculated based on the exhaust point and the preset overall packaging length. Control the preset exhaust device to move to the exhaust point and clamp the packaging bag, and control the exhaust device to move upward to exhaust the distance.

[0007] Optionally, when the photoelectric state matches the preset successful reception state and the venting point is determined, the venting method for the traditional Chinese medicine liquid packaging bag further includes: Determine the actual height of the liquid medicine based on the current venting point, and obtain the volume of the liquid medicine to be filled; The theoretical filling height corresponding to the volume of the filling liquid is determined based on the preset filling matching relationship; The filling deviation height is determined by calculating the difference between the theoretical filling height and the actual liquid height. Determine whether the filling deviation height is greater than the preset permissible deviation height; If the filling deviation height is not greater than the permissible deviation height, a normal filling signal is output and the exhaust device is moved. If the filling deviation height is greater than the permissible deviation height, an abnormal filling signal will be output.

[0008] Optionally, after the normal filling signal is output, the method for venting the traditional Chinese medicine liquid packaging bag also includes: A parallel detection path is established based on the exhaust point, and detection points are determined on the parallel detection path according to a preset unit distance. Control the through-beam device to move along a parallel detection path to obtain the through-beam status at the detection point; When the photo-transmitting state and the successful reception state are consistent, the corresponding detection point is defined as a success point, and the success points are counted to determine the number of successes, and the detection points are counted to determine the number of detections. The success rate is determined by calculating the number of successful tests and the number of tests conducted. Determine if the success rate is greater than the preset demand rate; If the success rate is greater than the demand rate, then control the movement of the exhaust device; If the success rate is not greater than the required rate, the exhaust point is updated based on the actual liquid height and the preset correction distance, and the success rate is judged again until the success rate is greater than the required rate.

[0009] Optionally, after an abnormal filling signal is output, the method for venting the traditional Chinese medicine liquid packaging bag also includes: A parallel detection path is established based on the exhaust point, and two boundary points are determined based on the parallel detection path, and the detection lateral width is determined based on the boundary points. The difference in horizontal width is determined by calculating the difference between the detected horizontal width and the preset horizontal width of the packaging. Determine whether the horizontal width of the difference is less than the preset baseline allowable width; If the difference in lateral width is not less than the baseline permissible width, then output a packaging tilt signal; If the difference in horizontal width is less than the baseline permissible width, then determine whether the filling deviation height is greater than the preset upper limit deviation height; If the filling deviation height is greater than the upper limit deviation height, a packaging bag damage signal will be output. If the filling deviation height is not greater than the upper limit deviation height, then an insufficient filling signal will be output.

[0010] Optionally, after the packaging tilt signal is output, the method for venting the herbal liquid packaging bag also includes: Obtain the liquid filling area; The internal volume of the packaging is determined based on the liquid filling area, and the difference between the internal volume of the packaging and the volume of the filled liquid is calculated to determine the filling deviation volume. Determine whether the filling deviation volume is less than the preset reasonable deviation volume; If the filling deviation volume is less than the reasonable deviation volume, then output a tilt normal signal; If the filling deviation volume is not less than the reasonable deviation volume, then a tilting abnormality signal will be output.

[0011] Optionally, the method also includes a step of determining the liquid-filled area, which includes: The two boundary points are taken as the original points, and the parallel detection paths corresponding to the two original points are defined as the original detection paths. The original detection paths are then adjusted downwards according to the preset adjustment height to reconstruct the parallel detection paths. The control device moves along a new parallel detection path to determine the boundary point, and the current boundary point is defined as the replacement point. The distance between points is determined by calculating the distance between the original point and the alternative point, and the distance between the points with the smallest value is determined according to the preset sorting rules. The alternative point corresponding to the distance between the points is defined as the binding point of the original point. Determine the extension direction based on the original point and the binding point, and establish a penetrating ray that extends towards the extension direction and passes through the binding point, starting from the original point. Determine whether two penetrating rays intersect; If the two penetrating rays do not intersect, the replacement point is updated to the new original point, and the original detection path is updated again until the two penetrating rays intersect. If the two penetrating rays intersect, the liquid filling area is determined based on the first determined parallel detection path and all penetrating rays.

[0012] Optionally, after the distance between the locations is determined, the method for venting the packaging bag of traditional Chinese medicine liquid also includes: Determine whether the distance between two points determined by a single original point is equal; If the distance between two points determined by a single origin point is not equal, then the binding point of the origin point is determined according to the distance between the points. If two points determined by a single original point are equidistant, then the first boundary segment is determined based on the original point and any alternative point, and the second boundary segment is determined based on another original point and another alternative point. When the first boundary segment and the second boundary segment do not intersect, the substitute point corresponding to the original point is determined as the binding point.

[0013] Secondly, the present invention provides a venting system for traditional Chinese medicine liquid packaging bags, which adopts the following technical solution: A degassing system for a traditional Chinese medicine liquid packaging bag, comprising: The acquisition module is used to acquire the filling status of the medicine solution; The processing module, connected to the acquisition and judgment modules, is used for information storage and processing; The judgment module, connected to the acquisition and processing modules, is used for judging information. When the judgment module determines that the filling status of the medicine liquid is consistent with the preset completed filling status, the processing module controls the through-beam device located on both sides of the packaging bag to move upward from the preset original position, and enables the acquisition module to acquire the through-beam status and through-beam movement distance of the through-beam device in real time. When the judgment module determines that the photoelectric state is consistent with the preset successful reception state, the processing module determines the exhaust point based on the current photoelectric movement distance and the original position, and calculates the exhaust movement distance based on the exhaust point and the preset overall packaging length. The processing module controls the preset exhaust device to move to the exhaust point and clamp the packaging bag, and controls the exhaust device to move upward to exhaust the distance.

[0014] In summary, the present invention has at least one of the following beneficial technical effects: 1. In the production process of traditional Chinese medicine, for the filled liquid packaging bags, the location of the liquid is determined according to the filling situation, and the exhaust device is controlled to remove the air in the remaining part, thereby reducing the air in the closed packaging bag and affecting the efficacy and shelf life of traditional Chinese medicine. 2. It can analyze the liquid residue on the packaging bag to improve the venting effect; 3. It can analyze situations such as tilting or damage to packaging bags to improve the stability of exhaust operations. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the following is combined with... Figures 1-9 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0025] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0026] This invention discloses a method for venting air from a traditional Chinese medicine liquid packaging bag. During the production of traditional Chinese medicine, the filling status of the liquid in the packaging bag can be analyzed to remove air from the unfilled portion, thereby reducing the amount of air remaining in the sealed packaging bag and affecting the efficacy and shelf life of the traditional Chinese medicine.

[0027] Reference Figure 1 The method for venting the packaging bag of traditional Chinese medicine liquid includes the following steps: Step S100: Obtain the filling status of the medicine solution.

[0028] The filling status of Chinese medicine refers to the filling status of Chinese medicine packaging bags, including three statuses: waiting to be filled, filling in progress, and filling completed.

[0029] Step S101: When the liquid filling state is consistent with the preset completed filling state, control the through-beam device located on both sides of the packaging bag to move upward from the preset original position, and obtain the through-beam status and through-beam movement distance of the through-beam device in real time.

[0030] The "Completed Filling State" refers to the state after the Chinese herbal medicine liquid to be filled has been filled into the packaging bag. When the filling state matches the "Completed Filling State," the packaging bag can be further processed. The "Through-Light Detector" is a device that includes an infrared transmitter and an infrared receiver, with the transmitter and receiver located on opposite sides of the packaging bag. When there is liquid between the Through-Light Detector and the Infrared Detector, the liquid will refract the infrared light, and the infrared receiver will not be able to receive the output signal from the infrared transmitter. The "Original Position" is the position set by the operator when the Through-Light Detector is not in operation. Controlling the Through-Light Detector to move upwards can distinguish the boundary between the liquid and liquid-free parts of the packaging bag, facilitating subsequent analysis. The "Through-Light Status" refers to whether the infrared receiver receives the infrared signal from the infrared transmitter. The "Through-Light Movement Distance" is the distance the Through-Light Detector moves upwards from its original position.

[0031] Step S102: When the photoelectric state is consistent with the preset successful reception state, determine the exhaust point based on the current photoelectric movement distance and the original position, and calculate the exhaust movement distance based on the exhaust point and the preset overall packaging length.

[0032] Successful reception status refers to the beam-through state when the infrared receiver receives the infrared signal from the infrared transmitter. When the beam-through state is consistent with the successful reception status, it means that no liquid is refracting the infrared light at that position, and the liquid in the packaging bag has been filled up to that position. The venting point is the point after moving the original position upwards along the current beam-through distance, which is also the initial point where venting is required. The overall length of the packaging bag is the overall length of the packaging bag in the height direction. The venting distance is the distance that needs to be vented in the packaging bag, which is determined by subtracting the venting point from the overall length of the packaging bag.

[0033] Step S103: Control the preset exhaust device to move to the exhaust point and clamp the packaging bag, and control the exhaust device to move upward to exhaust the distance.

[0034] An exhaust device is a device that clamps and moves a packaging bag. For example, it is composed of a stepper motor driver, a stepper motor, and a clamping assembly. The packaging bag can be clamped by the clamping assembly. At this time, controlling the entire exhaust device to move upward can remove the air from the part of the packaging bag that is not liquid. This results in less air content in the packaging bag after subsequent sealing, thereby reducing the impact of air on the efficacy and shelf life of traditional Chinese medicine.

[0035] Reference Figure 2 When the photoelectric state matches the preset successful reception state and the exhaust point is determined, the exhaust method for the traditional Chinese medicine liquid packaging bag also includes: Step S200: Determine the actual height of the liquid medicine based on the current venting point and obtain the volume of the liquid medicine to be filled.

[0036] The actual height of the liquid medicine is the total height of the liquid medicine filling the packaging bag, and the volume of the liquid medicine being filled is the volume of the liquid medicine being filled from the outside. This can be determined by installing a flow recording device at the outlet of the filling device.

[0037] Step S201: Determine the theoretical filling height corresponding to the filling liquid volume according to the preset filling matching relationship.

[0038] The theoretical filling height is the theoretical height that the liquid in the packaging bag should reach when the liquid volume is filled into the packaging bag. Different liquid volumes correspond to different theoretical filling heights, and the filling matching relationship between the two is determined by the staff in advance through multiple tests.

[0039] Step S202: Calculate the difference between the theoretical filling height and the actual liquid height to determine the filling deviation height.

[0040] The filling deviation height is the difference between the theoretical filling height and the actual liquid height, and this difference is an absolute value.

[0041] Step S203: Determine whether the filling deviation height is greater than the preset permissible deviation height.

[0042] The permissible deviation height is the maximum allowable filling deviation height set by the staff when they believe the medicine filling is normal and there are no issues such as damaged or tilted packaging bags. The purpose of this assessment is to determine whether the medicine filling is normal.

[0043] Step S2031: If the filling deviation height is not greater than the permissible deviation height, output a normal filling signal and control the movement of the exhaust device.

[0044] When the filling deviation height is not greater than the permissible deviation height, it indicates that there is no abnormality in the packaging bag. At this time, a normal filling signal can be output to control the exhaust device to perform exhaust operation.

[0045] Step S2032: If the filling deviation height is greater than the permissible deviation height, an abnormal filling signal is output.

[0046] When the filling deviation height is greater than the permissible deviation height, it indicates that there is an abnormal filling situation. At this time, an abnormal filling signal is output to identify the situation, so as to facilitate subsequent handling of the situation.

[0047] Reference Figure 3 After the normal filling signal is output, the methods for venting the packaging bag of traditional Chinese medicine liquid also include: Step S300: Establish a parallel detection path based on the exhaust point, and determine the detection point on the parallel detection path according to the preset unit distance.

[0048] After the normal filling signal is output, there may be residual liquid at other points on the packaging bag that are at the same level as the venting point, which requires further analysis; the parallel detection path is the device movement path that starts from the venting point and moves along the left or right until there are no obstacles between the two-way devices, and then turns around and moves to a point where there are no obstacles between the two-way devices; the unit distance is a fixed distance set by the staff, and the detection point can be marked at points that are at the same level as the venting point for easy subsequent analysis.

[0049] Step S301: Control the through-beam device to move along the parallel detection path to obtain the through-beam status at the detection point.

[0050] By controlling the movement of the photoelectric sensor, the photoelectric state at the detection point can be obtained, thereby revealing the liquid residue on the inner sidewall of the packaging bag.

[0051] Step S302: When the photoelectric state and the successful reception state are consistent, the corresponding detection point is defined as a success point, and the success points are counted to determine the number of successes, and the detection points are counted to determine the number of detections.

[0052] The detection points corresponding to the same photoelectric state and successful reception state are defined as success points to identify different detection points for subsequent analysis; the number of success points is the total number of determined success points, and the number of detection points is the total number of determined detection points.

[0053] Step S303: Calculate the success rate based on the number of successful tests and the number of tests.

[0054] The success rate is the ratio of successful points to all detection points, determined by dividing the number of successful points by the number of detection points.

[0055] Step S304: Determine whether the success rate is greater than the preset demand rate.

[0056] The demand percentage is the minimum success percentage that staff are required to ensure that the packaging bag can be properly vented without affecting the total amount of Chinese medicine. The purpose of this assessment is to determine whether the packaging bag can be properly vented.

[0057] Step S3041: If the success rate is greater than the demand rate, control the exhaust device to move.

[0058] When the success rate is greater than the demand rate, it indicates that the packaging bag can be properly vented. At this point, normal operation of the venting device is sufficient.

[0059] Step S3042: If the success rate is not greater than the required rate, calculate and update the exhaust point based on the actual liquid height and the preset correction distance, and then judge the success rate again until the success rate is greater than the required rate.

[0060] When the success rate is not greater than the demand rate, it indicates that when venting the packaging bag through the horizontal line of the venting point, there is a lot of liquid residue on the inner wall of the packaging bag, which will affect the total amount of Chinese medicine liquid during the venting process. Therefore, the venting point is raised by adding the correction distance to the actual liquid height, so that the actual working horizontal line of the venting device can be re-established to improve the overall venting operation effect; where the correction distance is the fixed distance set by the staff.

[0061] Reference Figure 4 After an abnormal filling signal is output, the method for venting the packaging bag of traditional Chinese medicine liquid also includes: Step S400: Establish a parallel detection path based on the exhaust point, determine two boundary points based on the parallel detection path, and determine the detection lateral width based on the boundary points.

[0062] Boundary points are the points on both sides where there are no obstacles when the through-beam device moves parallel to the parallel detection path. In other words, they are the two boundary points of the packaging bag in the width direction. The detection lateral width is the width of the packaging bag that the through-beam device can currently detect laterally. In other words, it is the straight-line distance between the two boundary points.

[0063] Step S401: Calculate the difference between the detected horizontal width and the preset packaging horizontal width to determine the difference horizontal width.

[0064] The horizontal width of the packaging is the width value of the packaging bag that the staff input in advance, that is, the width value that the packaging bag can reach after it is normally fixed and filled with liquid. The difference horizontal width is the difference between the detected horizontal width and the packaging horizontal width, and this difference is an absolute value.

[0065] Step S402: Determine whether the horizontal width of the difference is less than the preset baseline allowable width.

[0066] The baseline permissible width is the maximum allowable lateral width when the packaging bag is placed normally without significant tilting, as determined by the staff. The purpose of this determination is to determine whether the packaging bag is placed at an angle.

[0067] Step S4021: If the difference in lateral width is not less than the baseline permissible width, output a packaging tilt signal.

[0068] When the horizontal width of the difference is not less than the baseline permissible width, it indicates that the packaging bag is seriously tilted. At this time, a packaging tilt signal is output to identify the situation for subsequent analysis.

[0069] Step S4022: If the difference in horizontal width is less than the baseline allowable width, then determine whether the filling deviation height is greater than the preset upper limit deviation height.

[0070] When the horizontal width of the difference is less than the baseline permissible width, it indicates that the packaging bag is being placed normally. At this time, there may be a situation where the packaging bag is damaged and the liquid is leaking, which requires further analysis. The upper limit deviation height is the minimum filling deviation height that the staff sets when the volume of liquid in the packaging bag deviates significantly.

[0071] Step S40221: If the filling deviation height is greater than the upper limit deviation height, output a packaging bag damage signal.

[0072] When the filling deviation height is greater than the upper limit deviation height, it indicates that there is a large difference between the volume of liquid poured into the packaging bag and the existing volume of liquid in the packaging bag, that is, the packaging bag is damaged. Therefore, a packaging bag damage signal is output to identify the situation, so as to facilitate the intervention of staff.

[0073] Step S40222: If the filling deviation height is not greater than the upper limit deviation height, then output an insufficient filling signal.

[0074] When the filling deviation height is not greater than the upper limit deviation height, it indicates that there is no damage to the packaging bag. In this case, the insufficient liquid volume may be caused by the inaccurate counting of the liquid outlet flow device of the filling device. Therefore, an insufficient filling signal is output to identify this situation for subsequent analysis.

[0075] Reference Figure 5 After the packaging tilt signal is output, the method for venting the traditional Chinese medicine liquid packaging bag also includes: Step S500: Obtain the liquid filling area.

[0076] The liquid-filled area is the area in the packaging bag filled with traditional Chinese medicine liquid. It can be determined by acquiring images of the packaging bag and performing feature analysis, or by using the methods in steps S600-S6042.

[0077] Step S501: Determine the internal volume of the packaging based on the liquid filling area, and calculate the difference between the internal volume of the packaging and the volume of the filled liquid to determine the filling deviation volume.

[0078] The internal volume of the packaging is the volume of the Chinese medicine liquid that should be present in the liquid filling area. Different liquid filling areas should have different internal volumes of the packaging, which can be determined by multiplying the area by the set thickness parameter. This thickness parameter is the thickness value that the packaging bag will reach after liquid filling. The filling deviation volume is the difference between the internal volume of the packaging and the volume of the filled medicine liquid. This difference is an absolute value.

[0079] Step S502: Determine whether the filling deviation volume is less than the preset reasonable deviation volume.

[0080] The reasonable deviation volume is the maximum deviation volume that can be achieved when the liquid filling is considered to be normal, as set by the staff. The purpose of the judgment is to determine whether the current liquid filling is normal.

[0081] Step S5021: If the filling deviation volume is less than the reasonable deviation volume, output a tilt normal signal.

[0082] When the filling deviation volume is less than the reasonable deviation volume, it indicates that there is no problem with the internal liquid volume, that is, only the packaging bag is tilted. At this time, a tilt normal signal is output to mark the situation for subsequent analysis.

[0083] Step S5022: If the filling deviation volume is not less than the reasonable deviation volume, then output a tilting abnormality signal.

[0084] When the filling deviation volume is not less than the reasonable deviation volume, it indicates that there is not only a problem of the packaging bag being tilted, but also a problem of the packaging bag being damaged and leaking. At this time, a tilting abnormality signal is output to identify the situation, which is convenient for subsequent processing and analysis.

[0085] Reference Figure 6 It also includes a step of determining the liquid-filled area, which includes: Step S600: Take the two boundary points as the original points, define the parallel detection paths corresponding to the two original points as the original detection paths, and adjust the original detection paths downward according to the preset adjustment height to reconstruct the parallel detection paths.

[0086] Define the original point and the original detection path to facilitate the differentiation of different data and subsequent analysis; the height adjustment is the height value set by the staff to adjust the original detection path downwards. This value is fixed. By reconstructing the parallel detection path, the specific situation of the packaging bag can be known.

[0087] Step S601: Control the through-beam device to move on the new parallel detection path to determine the boundary point, and define the current boundary point as the replacement point.

[0088] Define alternative points to distinguish the current boundary points from the previous original points, which facilitates subsequent analysis.

[0089] Step S602: Calculate the distance between points based on the original point and the alternative point, determine the distance between points with the smallest value according to the preset sorting rules, and define the alternative point corresponding to the distance between the points as the binding point of the original point.

[0090] The distance between points is the straight-line distance between a single original point and a single replacement point. The sorting rule is a method set by the staff to sort the values, such as the bubble sort method. The sorting rule can determine the distance between points with the smallest value, that is, the replacement point at this distance is on the same side as the previous original point. At this time, it can be defined as the binding point.

[0091] Step S603: Determine the extension direction based on the original point and the binding point, and establish a penetrating ray that extends towards the extension direction and passes through the binding point, starting from the original point.

[0092] The extension direction is the direction from the original point to the binding point. A penetrating ray is established to determine the boundary line of the packaging bag, which facilitates subsequent analysis.

[0093] Step S604: Determine whether the two penetrating rays intersect.

[0094] The purpose of the judgment is to determine whether the lowest point of the packaging bag can be determined.

[0095] Step S6041: If the two penetrating rays do not intersect, update the replacement point to the new original point and update the original detection path again until the two penetrating rays intersect.

[0096] When the two penetrating rays do not intersect, it means that the lowest point of the packaging bag cannot be determined yet. In this case, continue to update the original detection path until the lowest point of the packaging bag can be determined.

[0097] Step S6042: If the two penetrating rays intersect, the liquid filling area is determined based on the first determined parallel detection path and all penetrating rays.

[0098] When two penetrating rays intersect, the lowest point of the packaging bag can be determined. At this point, the boundary line of the area with liquid on the packaging bag is determined. The liquid-filled area can then be determined based on all penetrating rays and parallel detection paths. The determination process is as follows: Figure 7 .

[0099] Reference Figure 8 After determining the distance between the locations, the methods for venting the packaging bags of traditional Chinese medicine liquid also include: Step S700: Determine whether the distance between two points determined by a single original point is equal.

[0100] The purpose of the judgment is to determine whether the binding point can be directly determined.

[0101] Step S7001: If the distance between two points determined by a single original point is not equal, then the binding point of the original point is determined according to the distance between the points.

[0102] When the distance between two points determined by a single origin point is not equal, it means that there is only one identifiable binding point. In this case, the binding point can be determined normally.

[0103] Step S7002: If the two points determined by a single original point are equidistant, then determine the first boundary segment based on the original point and any alternative point, and determine the second boundary segment based on another original point and another alternative point.

[0104] When two points determined by a single original point are equidistant, it indicates that both substitute points could potentially serve as binding points, requiring further analysis. Establishing a first boundary segment and a second boundary segment registers the binding status of the two original points and the two substitute points, facilitating subsequent analysis. Step S701: When the first boundary line segment and the second boundary line segment do not intersect, the substitute point corresponding to the original point is determined as the binding point.

[0105] When the first boundary line segment and the second boundary line segment do not intersect, it means that both line segments are on the boundary line of the packaging bag, that is, the current corresponding relationship is accurate, and the binding point of the original point can be determined based on the first boundary line segment and the second boundary line segment.
