Description

Technical Field

[0001] The present invention relates to the technical field of filling machines, and particularly to a method and device for monitoring the consumption of disinfectant liquid by a filling machine and a filling machine. Background Art

[0002] Under the existing dairy production conditions, the sterilization methods of the filling machine for raw and auxiliary materials and packaging materials are different. Usually, disinfectant liquid needs to be injected into the filling machine to achieve the sterilization of raw and auxiliary materials and packaging materials. Currently, hydrogen peroxide is mostly used as a disinfectant to carry out sterilization through the oxidation reaction of H 2 O 2 It can be seen that hydrogen peroxide is the most fundamental factor to ensure the complete sterilization of raw and auxiliary material equipment and the most important guarantee for product quality.

[0003] However, the existing filling machines can only monitor the concentration and temperature of the disinfectant liquid. For the monitoring of the consumption of disinfectant liquid, the current measures are achieved by manually monitoring the weight each time hydrogen peroxide is replaced or supplemented. However, since the time interval for manually supplementing hydrogen peroxide is relatively long, real-time monitoring of the consumption of hydrogen peroxide cannot be achieved, and the timeliness is poor and the measurement accuracy is low. In addition, for production products with high requirements for sterile environments such as dairy products, it is also impossible to monitor the consumption of disinfectant liquid by introducing a monitoring device such as a flow meter inside the filling machine that may affect the sterile environment. Moreover, after the reaction of disinfectant liquids such as hydrogen peroxide, waste water will flow back into the device for holding the disinfectant liquid in the filling machine, thus affecting the accuracy of the measurement results of the flow meter. Therefore, how to accurately monitor the consumption of disinfectant liquid by a filling machine is of great significance for ensuring the production quality of products such as dairy products.

[0045] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0046] The technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0047] Under the existing dairy production conditions, the sterilization methods of the filling machine for the raw and auxiliary material packaging materials are different. Usually, it is necessary to inject disinfectant into the filling machine to achieve the sterilization of the raw and auxiliary material packaging materials. Currently, hydrogen peroxide is mostly used as a disinfectant to carry out sterilization through the oxidation reaction of H 2 O 2 . It can be seen that hydrogen peroxide is the most fundamental factor to ensure the complete sterilization of the raw and auxiliary material equipment and the most important guarantee for the actual product quality.

[0048] However, the existing filling machines can only monitor the concentration and temperature of the disinfectant. For the monitoring of the consumption of the disinfectant, the current measures are achieved by manually monitoring the weight each time the hydrogen peroxide is replaced and supplemented. However, since the time interval for manually supplementing hydrogen peroxide is relatively long, the real-time monitoring of the consumption of hydrogen peroxide cannot be achieved, and the timeliness is poor and the measurement accuracy is low. In addition, for production products with high requirements for aseptic environment such as dairy products, it is also impossible to monitor the consumption of the disinfectant by introducing monitoring devices such as flow meters inside the filling machine that will affect the aseptic environment. Moreover, after the reaction of disinfectants such as hydrogen peroxide, wastewater will flow back into the device for storing the disinfectant in the filling machine, thus affecting the accuracy of the measurement results of the flow meter. Therefore, how to achieve accurate monitoring of the consumption of the disinfectant in the filling machine is of great significance for ensuring the production quality of products such as dairy products.

[0049] Based on the above problems, the embodiments of the present invention provide a method for monitoring the consumption of the disinfectant in a filling machine. As Figure 1 shown, the filling machine includes: a filling machine body 1 and a controller 2. Among them, a peristaltic pump 3 is arranged at the disinfectant supplement end of the filling machine body 1. The peristaltic pump 3 supplements the external disinfectant into the interior of the filling machine, and the peristaltic pump 3 is a constant-frequency peristaltic pump.

[0050] As Figure 2 shown, the method for monitoring the consumption of the disinfectant in the filling machine provided by the embodiments of the present invention is applied to the controller 2 as Figure 1 shown, and specifically includes the following steps:

[0051] Step S101: Monitor the disinfectant replenishment signal sent by the filling machine and the corresponding time.

[0052] Specifically, in order to avoid system alarms, the embodiments of the present invention do not modify the original system of the filling machine, and provide an automatic control system independent of the system. For example, an external PLC is built. By connecting the PLC to the contactor of the existing filling machine system and judging the operating state of the filling machine through the action of the contactor. Among them, when the hydrogen peroxide concentration is low, the contactor will be triggered to close. The PLC receives the closing situation of the contactor to obtain the disinfectant replenishment signal sent by the filling machine and records the closing time. In addition, when the PLC monitors that the contactor is in the closed state, it will control the peristaltic pump to operate, so as to supplement external disinfectant such as hydrogen peroxide into the filling machine until the contactor changes from the closed state to the open state, which indicates that the hydrogen peroxide concentration meets the preset concentration requirement of the filling machine, and the replenishment of hydrogen peroxide stops. Specifically, the PLC program detects the closing situation of the contactor in each cycle period, and controls the industrial frequency pump to operate once in each program scan period until the low hydrogen peroxide concentration signal is restored, and the system stops injecting hydrogen peroxide. During the operation, the operating state of the filling machine is judged in real time, and the delay of the program is increased to avoid false signals, etc.

[0053] Step S102: Obtain the start times of the peristaltic pump between the previous disinfectant replenishment signal and the current disinfectant replenishment signal.

[0054] Specifically, when the filling machine sends two consecutive disinfectant replenishment signals, the consumption of the disinfectant during the period between the two disinfectant replenishment signals is the amount of hydrogen peroxide replenished from the outside to the filling machine by the peristaltic pump. Therefore, the hydrogen peroxide consumption can be determined by obtaining the start times of the peristaltic pump during this period.

[0055] Step S103: Determine the current time period based on the first time corresponding to the previous disinfectant replenishment signal and the second time corresponding to the current disinfectant replenishment signal.

[0056] Specifically, the current time period is the time difference between the times corresponding to the occurrence times of two consecutive disinfectant replenishment signals. In practical applications, when the hydrogen peroxide consumption of the filling machine in the current working state increases, the current time period will be shortened; conversely, the current time period will be extended. Thus, the real-time consumption can be monitored according to the actual working state of the filling machine, which is more in line with the production reality and improves the accuracy of the real-time consumption.

[0057] Step S104: Calculate the real-time disinfectant consumption of the filling machine in the current time period based on the single injection volume of the peristaltic pump and the start times.

[0058] Specifically, since the peristaltic pump is a fixed-frequency peristaltic pump, the single injection volume of hydrogen peroxide is fixed and can be obtained in advance according to the current actual production conditions. Exemplarily, the peristaltic pump is driven to operate by a hydrogen peroxide replenishment signal (contactor closing) (after the cycle ends, if there is a replenishment signal, the peristaltic pump operates again once), the cumulative replenishment time is measured, and the register accumulates the differential replenishment time of the hydrogen peroxide consumption to calculate the real-time hydrogen peroxide consumption.

[0059] In addition, based on the dairy production conditions (the flow monitoring in dairy production is rough and has a fluctuation range, without the need to be accurate to the second or milliliter level), the signal delay can be used to process the abnormalities that occur during the addition process of the hydrogen peroxide system and perform filtering, so as to further improve the accuracy of the real-time consumption result of the disinfectant.

[0060] By performing the above steps, the method for monitoring the disinfectant consumption of the filling machine provided by the embodiment of the present invention sets a fixed-frequency peristaltic pump at the disinfectant replenishment end of the filling machine, uses the peristaltic pump to supplement the external disinfectant into the filling machine, and then determines the total injection volume of the disinfectant in the current time period by monitoring the number of times the peristaltic pump works between two consecutive disinfectant replenishment signals of the filling machine, and further determines the real-time disinfectant consumption in the current time period, thereby realizing the accurate monitoring of the disinfectant consumption of the filling machine. The real-time performance and accuracy meet the actual product production requirements and are beneficial to the monitoring of product quality.

[0061] Specifically, in one embodiment, step S104 described above specifically includes the following steps:

[0062] Step S201: Obtain the historical monitoring data of the peristaltic pump injecting disinfectant into the filling machine.

[0063] Step S202: Determine the single injection volume based on the historical monitoring data.

[0064] Specifically, the proportionality coefficient of the peristaltic pump pumping is calculated in combination with the operation of the dairy production conditions (that is, the amount of hydrogen peroxide replenished each time the peristaltic pump starts, and this proportionality coefficient is the amount of liquid injected each time the pump starts). Through actual measurement and repeated verification, the standard proportionality coefficient is obtained, and the hydrogen peroxide replenishment amount is calculated by counting the action frequency of the pump.

[0065] Furthermore, in combination with the current situation of the dairy production conditions, on the basis of not changing the current situation of the filling machine equipment, the embodiment of the present invention adds a power-frequency peristaltic pump to the pipeline from the hydrogen peroxide bucket to the hydrogen peroxide tank to fix the operation time of each pump. In this way, the influence of whether the pipe is full on the measurement of the pumped liquid volume can be ignored. At the same time, the power-frequency pump with a fixed start time has a stable pumping volume each time, reducing the frequency error during each replenishment to further improve the accuracy of the real-time disinfectant consumption of the filling machine.

[0066] Specifically, in one embodiment, before performing the above step S102, the above method for monitoring the consumption of disinfectant solution by the filling machine further includes the following steps:

[0067] Step S301: Obtain the first working state of the filling machine corresponding to the first time and the second working state corresponding to the second time.

[0068] Specifically, taking dairy product production as an example, during the product production process of the filling machine, there are: startup process, heating process, production process, etc. Exemplarily, the above PLC can be connected to the filling machine to monitor the signals of different contactors, and then the PLC processes the corresponding signals to judge the working state of the filling machine.

[0069] Step S302: Determine whether the first working state and the second working state are in the same working stage; when the first working state and the second working state are in the same working stage, perform step S102. When the first working state and the second working state are in different working stages, return to step S101.

[0070] Specifically, due to the large differences in the supplementary amount and consumption amount of hydrogen peroxide when the filling machine is in different working states, during the first startup, i.e., during the startup process, the measured liquid volume is the supplementary amount of the hydrogen peroxide tank; during the heating process, the measured liquid volume is the consumption amount of hydrogen peroxide for environmental sterilization; during the production process, the measured liquid volume is the consumption amount of hydrogen peroxide for package sterilization. Thus, by ensuring that the filling machine is in the same working state during two consecutive disinfection rate supplementary signal emissions, the influence of different working states on the real-time consumption result of the disinfectant solution is avoided, so as to further improve the accuracy of the real-time consumption of the disinfectant solution by the filling machine.

[0071] Specifically, in one embodiment, the above method for monitoring the consumption of disinfectant solution by the filling machine further specifically includes the following steps:

[0072] Step S401: Obtain the target monitoring requirement.

[0073] Step S402: Based on the target monitoring requirement, determine the target monitoring time of the filling machine; within the target monitoring time, perform step S101.

[0074] Specifically, the target monitoring requirement can be a requirement determined according to the working state of the filling machine. For example, the monitoring requirement is the monitoring of the production stage, or it can also be the monitoring of a specific time period within the production stage, such as: from 8:00 to 10:00 every day, etc. The present invention only takes this as an example and is not limited thereto. Thus, by setting the target monitoring requirement, the real-time consumption of the disinfectant solution of the filling machine in different working states and different working times can be monitored flexibly, which is beneficial to providing accurate data support for the product disinfection situation and is beneficial to the monitoring of product quality.

[0075] The following will combine specific application examples to provide a detailed description of the method for monitoring the consumption of disinfectant liquid by the filling machine provided by the embodiments of the present invention.

[0076] Due to the particularity of the dairy production working conditions, the existing filling machine automatically extracts hydrogen peroxide from the hydrogen peroxide bucket to supplement the hydrogen peroxide tank. In the actual use process, the measurement by the flow meter may cause errors due to the non-full pipe of the product hose pipeline, the measurement by weighing the hydrogen peroxide bucket will cause errors due to insufficient accuracy (the hydrogen peroxide is in a circulating state and the weight of the iron bucket itself is relatively high), and the measurement by the liquid level change of the liquid level probe will cause errors due to the irregular shape of the hydrogen peroxide bucket program. The embodiments of the present invention build a fully automated real-time consumption platform for hydrogen peroxide. An external PLC and a peristaltic pump are provided, and the proportional coefficient of the action frequency of the peristaltic pump and the hydrogen peroxide injection amount is counted. The system automatically converts the real-time consumption of hydrogen peroxide, obtains the real-time curve of the hydrogen peroxide consumption amount, and then retrieves the real-time curve of the hydrogen peroxide consumption amount and sets the upper and lower limits, and can display the consumption situation in real time. The working process of the method for monitoring the consumption of disinfectant liquid by the filling machine provided by the embodiments of the present invention is as Figure 3 shown.

[0077] This method builds a completely independent set of consumption monitoring system on the basis of the original functions of the filling machine equipment, without changing the components in the original system structure. During the system construction process, additional hard wiring is added to the original contactor, and signals are connected through the connected contactor hard wiring to judge the operating state of the corresponding filling machine (for example, during the heating process, judge the heating state by monitoring the suction of contactors such as blowing and lubricating oil injection). At the same time, for the hardware system of the equipment, an additional Siemens S7-200 PLC and corresponding IO modules are configured to form an independent lower computer control system. In order to better control the lower computer, an upper computer control system is built and combined with a touch screen for control, and finally a complete closed-loop system is formed.

[0078] In order to more intuitively observe the operating state of the equipment and the consumption amount during the production process, by writing a touch screen program, the consumption data of the equipment, the operating state of the equipment, and the consumption curve of each period of the equipment are all fully displayed on the touch screen, and at the same time, a historical data group is added to facilitate the query of the historical data of the equipment.

[0079] The upper computer system has the function of intuitively displaying all process data, which is convenient for monitoring the consumption state of hydrogen peroxide and operating key data. At the same time, parameter alarm values are set, that is, when the consumption amount is too high or too low, the system has an alarm function;

[0080] The host computer system has permission management. The highest permission can retrieve the specific values of each segment of historical data, and the relevant parameter values (parameter values within the standard limit range) can be exported. The real-time operating conditions of the equipment can be judged through linear regression analysis, that is, integrating the time and the parameter values of historical real-time consumption to fit the data into a parameter equation, and calculating the regression coefficient. Analyze the real-time situation of the equipment through the directivity of parameters such as the regression coefficient and the uncertainty slope. When the general trend of the consumption data points upward, there may be an excessive demand for the hydrogen peroxide system, and the corresponding packaging materials and system leakage problems are analyzed; vice versa. Under specific dairy production conditions, warn the equipment status in specific production steps, and conduct real-time monitoring of the equipment conditions in a targeted manner to perform preventive maintenance on the equipment. This system can realize the real-time monitoring of the hydrogen peroxide consumption, and at the same time has the functions of product quality guarantee traceability and permission management. The accuracy of the automatic production consumption monitoring and manual weighing of the system can reach more than 98%, which can completely replace the original manual records and realize automatic supervision.

[0081] By performing the above steps, the method for monitoring the consumption of the disinfectant of the filling machine provided by the embodiment of the present invention sets a constant-frequency peristaltic pump at the disinfectant replenishment end of the filling machine, uses the peristaltic pump to replenish the external disinfectant into the interior of the filling machine, and then determines the total injection amount of the disinfectant in the current time period by monitoring the number of times the peristaltic pump works between two consecutive disinfectant replenishment signals of the filling machine, and further determines the real-time consumption of the disinfectant in the current time period, thereby realizing the accurate monitoring of the consumption of the disinfectant of the filling machine, and the real-time performance and accuracy meet the actual product production requirements, which is beneficial to the monitoring of product quality.
