Description

Technical Field

[0001] The invention relates to the technical field of filling and sealing machines, and in particular to a filling and sealing machine sealing quality optimization evaluation system and equipment. Background Art

[0002] Filling and sealing machines are widely used in the food, beverage, cosmetic and pharmaceutical industries. Their main function is to accurately fill liquid or fluid products into various containers and then effectively seal them to prevent leakage and contamination. According to different needs, these machines can be divided into liquid, paste or powder filling machines, and the sealing methods include heat sealing, capping and pressing capping. According to the degree of automation, they can be divided into fully automatic and semi-automatic types.

[0003] Heat-sealing filling and sealing machines are suitable for most products whose containers are made of plastic, such as disposable tubes, cosmetic tubes, etc. When heat-sealing, a hot air gun is used to blow hot air on both sides of the tube mouth. The heat softens and melts the sealing area of ​​the material, and then pressure is applied through the clamp to ensure that the two material surfaces are in close contact.

[0004] The sealing quality of the sealing machine can be directly reflected by checking the airtightness of the product after sealing. However, the product needs to go through the unloading process before it can be checked after being sealed by the sealing machine. During the unloading process, the sealing of the product may be affected by vibration, falling, etc. Therefore, it is not accurate to reflect the sealing quality of the sealing machine by the sealing quality of the product. Summary of the invention

[0005] In view of the problems existing in the above-mentioned prior art, the object of the present invention is to provide a filling and sealing machine sealing quality optimization evaluation system and equipment, so as to judge the sealing quality of the sealing machine.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a filling and sealing machine sealing quality optimization and evaluation system, comprising: a parameter acquisition module: used to obtain the flatness of the clip of the clamp in the sealing machine under standard pressure, and record the data of the clip flatness; at the same time, set the clip flatness threshold, and input the clip flatness threshold and the clip flatness together into the parameter comparison module; parameter comparison module: used to compare the clip flatness and the clip flatness threshold, and input the comparison result into the operation corresponding module; operation corresponding module: used to make different responses according to the comparison result, wherein, when the clip flatness is greater than the clip flatness threshold, the system shuts down and prompts the staff to replace the clip; when the clip flatness is less than or equal to the clip flatness threshold, the system operates normally.

[0007] In some embodiments, a pressurized flatness threshold is set, and the pressurized flatness threshold is less than the flatness threshold. When the flatness of the clip reaches the pressurized flatness threshold, the standard pressure is pressurized to improve the sealing quality.

[0008] In some embodiments, the theoretical working hours of the sealing machine clip under the standard pressure are obtained, and after the standard pressure is pressurized, it is determined whether the theoretical working hours can still be achieved. The specific method is as follows: Step 1: Obtain theoretical remaining working hours and elapsed working hours based on theoretical working hours; Step 2, obtaining the average daily increase of the flatness of the clip according to the flatness of the clip and the elapsed working hours; Step 3, obtaining the pressure growth rate according to the pressurization pressure, and obtaining the daily average growth of the pressurization flatness according to the pressure growth rate; Step 4: Obtain the remaining theoretical working hours after pressurization based on the average daily increase in pressurized flatness. Compare the remaining theoretical working hours after pressurization with the theoretical remaining working hours to determine whether it can be achieved.

[0009] In some embodiments, the specific method for obtaining the theoretical remaining working hours and the elapsed working hours based on the theoretical working hours is: the flatness of the clip on the sealing machine clamp is monitored in real time, and when the flatness of the clip reaches the pressurized flatness threshold, the number of days currently worked is obtained and recorded as the elapsed working hours, and the theoretical working hours minus the elapsed working hours equals the theoretical remaining working hours.

[0010] In some embodiments, a specific method for obtaining the average daily increase in clip flatness based on the clip flatness and the elapsed working hours is: the clip flatness is divided by the elapsed working hours to obtain the average daily increase in clip flatness.

[0011] In some embodiments, the pressure growth rate is obtained based on the pressurized pressure, and the specific method for obtaining the daily average increase of the pressurized flatness based on the pressure growth rate is: the pressure growth rate is equal to the pressurized pressure minus the standard pressure divided by the percentage of the standard pressure. As the pressure increases, the flatness of the clip also increases, so the daily average increase of the pressurized flatness is equal to the pressure growth rate plus one multiplied by the daily average increase of the flatness multiplied by the proportional factor.

[0012] In some embodiments, a specific method for obtaining the remaining theoretical working hours after pressurization based on the average daily increase in pressurized flatness is: the flatness threshold minus the clip flatness divided by the average daily increase in pressurized flatness.

[0013] In some embodiments, after determining that the sealing machine clip can run to the theoretical working hours, different response strategies are made according to different judgment results. When it can run to the theoretical working hours, it runs normally. When it cannot run to the theoretical working hours, it is determined whether the remaining working hours after pressurization can reach half of the theoretical remaining working hours. If it cannot reach it, pressurization is stopped. If it can reach it, pressurization is maintained.

[0014] The present invention also provides the following technical solutions: The present invention further provides a filling and sealing machine sealing quality optimization and evaluation device, comprising a memory and a processor coupled to the memory, wherein the processor is configured to execute the above-mentioned filling and sealing machine sealing quality optimization and evaluation system based on instructions stored in the memory.

[0015] The present invention further provides a computer-readable storage medium, wherein the computer-readable storage medium stores a computer program, and the computer program is executed by a processor to implement the above-mentioned filling and sealing machine sealing quality optimization evaluation system.

[0016] Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: First, in the present invention, a flatness threshold is set for the clip, and the flatness actually measured is compared with the flatness threshold, and the sealing quality of the sealing machine can be judged according to the comparison result. Because if the flatness is less than or equal to the flatness threshold, it means that the flatness of the clip is within the qualified range, and the sealing quality of the product sealed by the sealing machine is also within the qualified range. If the flatness is greater than the flatness threshold, it means that the flatness of the clip exceeds the qualified range, and the sealing quality of the product sealed by the sealing machine using this clip is also not within the qualified range.

[0017] Secondly, in the present invention, after it is determined that the clamp of the sealing machine is within the qualified range, the standard pressure can be pressurized to ensure the production quality. Because although it is within the qualified range, the flatness has been increasing. When the flatness gradually approaches the flatness threshold, the sealing quality is closer to the qualified bottom line, so a pressurized flatness threshold can be set. When the flatness reaches the pressurized flatness threshold, pressurization is performed to ensure the sealing quality. In addition, after pressurization, the increase in flatness will be accelerated to determine whether it can still run to the original time after pressurization. First, the theoretical working hours and pressurized flatness threshold of the sealing machine under standard pressure are preset. When the flatness of the clamp of the sealing machine clamp reaches the pressurized flatness threshold, the time that the clamp has worked at this time is obtained, and the theoretical working hours minus the time that has worked are obtained. The theoretical remaining working hours are obtained. Secondly, the average daily increase in flatness was obtained using the flatness of the clamp and the elapsed working hours, and the pressure growth rate was obtained using the pressurization pressure. Because the pressure growth rate and the average daily increase in flatness are in the same proportion, the theoretical remaining working hours after pressurization can be obtained based on these two parameters. By comparing the theoretical remaining working hours after pressurization with the theoretical remaining working hours, it can be determined whether the clamp on the sealing machine fixture can still work up to the theoretical working hours after the standard pressure is applied.

[0018] Third, after determining whether the clamps on the sealing machine clamp can still work to the theoretical working hours, determine whether the theoretical remaining working hours after pressurization are half of the theoretical remaining working hours. If it cannot reach half of the theoretical remaining working hours, it means that pressurization has greatly shortened the working hours of the clamps of the sealing machine clamp. At this time, to avoid this situation, pressurization can be stopped. If it reaches half of the theoretical remaining working hours, it means that the working hours of the clamps of the sealing machine clamps shortened by pressurization are within an acceptable range. At this time, in order to ensure the sealing quality, pressurization can be maintained. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a schematic diagram of the system module of the present invention; Figure 2 It is a schematic diagram of the judgment logic that the clamp in the present invention can run to the theoretical working hours after being pressurized. DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0022] The filling and sealing machine sealing quality optimization evaluation system provided by the present invention is as follows: Figure 1 and Figure 2 As shown, including: Parameter acquisition module: This module uses sensors to measure the flatness of the clips in the current sealing machine in real time under standard pressure, and records the specific values ​​of the clip flatness for subsequent comparison and reference. At the same time, the clip flatness threshold is set according to the actual production situation. This clip flatness threshold represents the minimum limit. Under this clip flatness threshold, the product seal processed by the sealing machine meets the minimum quality standard.

[0023] Parameter comparison module: This module compares the flatness of the clip and the clip flatness threshold, and determines whether the clip flatness is within the qualified range based on the comparison result, and then makes different operation modes based on whether the clip flatness is within the qualified range or not. Because, although for a sealing machine, the parameters affecting the sealing quality mainly include factors such as melting temperature, clamping time, and clip flatness. However, on the one hand, the melting temperature is usually set to a reasonable temperature based on the material, and this temperature will not change when the sealing machine is working; on the other hand, the clamping time is also set according to the production line conditions and production experience, and this clamping time will not change. However, the flatness of the clip will gradually wear and change with the increase of use time. Therefore, compared with the flatness of the clip, these two factors are unlikely to affect the sealing quality. Therefore, the present invention mainly judges the sealing quality of the sealing machine by detecting the flatness of the clip.

[0024] Operation response module: In this module, when the flatness of the clip is greater than the flatness threshold of the clip, it means that the flatness of the clip exceeds the minimum standard of the sealing quality of the sealing machine. Therefore, when this happens, the operation required is to stop the machine and immediately replace the clip of the clamp. When the flatness of the clip is less than or equal to the flatness threshold of the clip, it means that the flatness of the clip is within the qualified standard sealing range that the sealing machine can seal, and the sealing machine can work normally. In this case, although the sealing machine can work normally, the closer the flatness of the clip is to the flatness threshold, the more likely it is that the sealing quality of the product sealed by the sealing machine will be unqualified. Because, in order to ensure production quality, the pressure of the clamp clip can be increased when it approaches the flatness threshold to ensure the sealing quality. The specific method is as follows: First, obtain the time that the sealing machine clip can work under standard pressure, which is recorded as the theoretical working hours. At the same time, set a pressure flatness threshold that is less than the flatness threshold. Monitor the flatness of the clip on the sealing machine fixture in real time. When the flatness of the clip reaches the pressure flatness threshold, obtain the number of days that have been working, which is recorded as the elapsed working hours. The theoretical working hours minus the elapsed working hours equals the theoretical remaining working hours. The clip flatness is divided by the elapsed working hours to get the average daily increase in clip flatness.

[0025] Secondly, when the flatness of the clip reaches the flatness threshold of pressurization, the clip is pressurized, the pressurization pressure is set, and the pressure growth rate is obtained according to the pressurization pressure. The pressure growth rate is equal to the percentage of the pressurization pressure minus the standard pressure divided by the standard pressure. Because the pressure increases, the flatness of the clip also increases. Therefore, according to the pressure growth rate, it can be obtained that the average daily increase of pressurized flatness is equal to the pressure growth rate plus one multiplied by the average daily increase of flatness multiplied by the proportional factor k. According to the average daily increase of pressurized flatness, the remaining theoretical working hours after pressurization are obtained. The remaining theoretical working hours after pressurization are equal to the flatness threshold minus the clip flatness divided by the average daily increase of pressurized flatness. Compare the remaining theoretical working hours after pressurization with the theoretical remaining working hours to determine whether it can still operate normally to the theoretical working hours after pressurization. For example, assume that the theoretical working hours are 100 days, the flatness threshold is 1, and the proportional factor is 1. The pressurized flatness threshold is 0.8. When the measured flatness reaches 0.8, assuming that the current working hours are 85 days, the remaining theoretical working hours are 15 days, and the average daily increase in the flatness of the clip is 0.8÷85=0.0094. Assuming that the theoretical pressure is 10kgf and the pressurization pressure is 12kgf, the pressure growth rate is (12-10)÷10=20%, and the average daily increase in the pressurized flatness is Zb=(1+20%)×0.0094=0.01128, so the theoretical remaining working hours after pressurization = (1-0.8)÷0.01128=17. The 17 obtained is the theoretical remaining working hours after pressurization, 17 days. Because 17 days is greater than 15 days, the remaining working hours after pressurization are sufficient, indicating that it can also operate normally under the theoretical working hours after pressurization. If the remaining working hours after pressurization are insufficient, for example, the remaining working hours are 5 days, which cannot even reach half of the theoretical remaining working hours, then stop pressurization. If the remaining working time is 10 days, which is more than half of the theoretical remaining working time of 15 days, then in order to ensure the sealing quality, the pressure can be maintained.

[0026] In addition, on the one hand, the present invention provides a filling and sealing machine sealing quality optimization and evaluation device, including a memory and a processor coupled to the memory, the processor being configured to execute the above-mentioned filling and sealing machine sealing quality optimization and evaluation system based on instructions stored in the memory; on the other hand, the present invention provides a computer-readable storage medium, the computer-readable storage medium storing a computer program, the computer program being executed by the processor to implement the above-mentioned filling and sealing machine sealing quality optimization and evaluation system.

[0027] In general, the present invention sets a flatness threshold for the clip, compares the flatness actually measured with the flatness threshold, and judges the sealing quality of the sealing machine according to the comparison result. Because if the flatness is less than or equal to the flatness threshold, it means that the flatness of the clip is within the qualified range, and the sealing quality of the product sealed by the sealing machine is also within the qualified range. If the flatness is greater than the flatness threshold, it means that the flatness of the clip exceeds the qualified range, and the sealing quality of the product sealed by the sealing machine using this clip is also not within the qualified range. After judging that the clip of the sealing machine clamp is within the qualified range, in order to ensure the production quality, the standard pressure can be pressurized. Because although it is within the qualified range, the flatness is already increasing. When the flatness gradually approaches the flatness threshold, the sealing quality is closer to the qualified bottom line, so the pressure flatness threshold can be set. When the flatness reaches the pressure flatness threshold, pressurization is performed to ensure the sealing quality. In addition, after pressurization, the increase of flatness will be accelerated to judge whether it can still run to the original time after pressurization. First, the theoretical working hours and pressurized flatness threshold of the sealing machine under standard pressure are preset. When the flatness of the clamp of the sealing machine fixture reaches the pressurized flatness threshold, the time that the clamp has worked is obtained. The theoretical working hours minus the time that has worked is the theoretical remaining working hours. Secondly, the flatness of the clamp and the time that has worked are used to obtain the average daily increase in flatness, and the pressure growth rate is obtained using the pressurized pressure. Because the pressure growth rate and the average daily increase in flatness are in the same proportion, the theoretical remaining working hours after pressurization can be obtained based on these two parameters. By comparing the theoretical remaining working hours after pressurization with the theoretical remaining working hours, it can be judged whether the clamp on the sealing machine fixture can still work to the theoretical working hours after pressurization of the standard pressure. After judging whether the clamp on the sealing machine fixture can still work to the theoretical working hours, it is judged whether the theoretical remaining working hours after pressurization are half of the theoretical remaining working hours. If it cannot reach half of the theoretical remaining working hours, it means that pressurization has greatly shortened the working time of the clamp of the sealing machine fixture. At this time, to avoid this situation, pressurization can be stopped. If it reaches half of the theoretical remaining working time, it means that the working time of the clamp of the compression short sealing machine is within an acceptable range. At this time, in order to ensure the sealing quality, the pressurization can be maintained.
