Description

Technical Field

[0001] This invention relates to the field of pressure relief detection for wine bottling machines, and more particularly to a method for pressure relief detection for wine bottling machines. Background Technology

[0002] During the bottling process of canned beer, issues such as beer overflowing from the valve, unstable liquid level, and unstable TPO (total oxygen content in beer and headspace oxygen content) may occur. Each time, the machine needs to be stopped to check the level gauge, control solenoid valve, and valve seals of the beer valve. If the fault cannot be determined, spare parts must be replaced in sequence, and the problem must be investigated step by step. This troubleshooting process results in long downtime, significant efficiency loss, high cost of spare parts replacement, and serious waste. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a pressure relief detection method for a wine bottling machine, thereby solving the problems of high costs in troubleshooting and replacing spare parts.

[0004] This invention provides a method for detecting pressure relief in a wine bottling machine, comprising the following steps:

[0005] A pressure relief detection device is installed on the filling valve of the wine filling machine, and the pressure relief detection device includes a pressure gauge;

[0006] The bottling machine is controlled by jogging, so that the bottling machine performs different working areas in batches, and the pressure gauge value of the pressure relief detection device is observed.

[0007] If the pressure gauge reading of the pressure relief detection device fluctuates within the currently executed work area, the pressure relief module of the bottling machine is determined based on the control parameters of the bottling machine and the currently executed work area; wherein the currently executed work area is determined by a time comparison parameter table of the bottling machine executing different work areas in stages.

[0008] In one optional implementation, the currently executed work area is determined by a time reference parameter table of the wine bottling machine executing different work areas in stages, including:

[0009] The current working area is determined by the carbon dioxide flushing time, carbon dioxide tank entry time, maximum dispensing time, pressure relief time, residual liquid spraying time, and segmented cleaning time set in the operating parameters of the bottling machine.

[0010] In one alternative embodiment, if the pressure gauge reading of the pressure relief detection device fluctuates during the carbon dioxide flushing time, then at least one of the quick filling valve, CO2 displacement exhaust valve, or liquid inlet valve is identified as a pressure relief module.

[0011] In one alternative implementation, if the pressure gauge reading of the pressure relief detection device fluctuates during the carbon dioxide inlet time, the CO2 replacement exhaust valve or liquid inlet valve is identified as the pressure relief module.

[0012] In one alternative embodiment, if the pressure gauge reading of the pressure relief detection device fluctuates during the maximum time of alcohol dispensing, then at least one of the level gauge, electromagnetic flow meter valve, slow filling valve, fast filling valve, or inlet valve is identified as a pressure relief module.

[0013] In one alternative implementation, if the pressure gauge value of the pressure relief detection device in the currently executed work area fluctuates compared with the control parameters of the wine bottling machine, it is determined that a pressure relief module exists in the currently executed work area.

[0014] In one optional embodiment, the control parameter of the bottling machine is the pressure value of carbon dioxide, which is a fixed value. If the pressure gauge value of the pressure relief detection device is less than the pressure value of carbon dioxide, it is determined that there is a pressure relief module in the carbon dioxide flushing working area.

[0015] In one optional embodiment, the step of determining the pressure relief module of the wine bottling machine based on the control parameters of the wine bottling machine and the currently executed working area includes:

[0016] Based on the low liquid level statistics of the bottling machine, the pressure relief station involved in the currently executed work area is determined. If there is a difference between the pressure gauge value and the pressure parameter displayed on the screen of the bottling machine, it is determined that the seal associated with the currently executed work area has a pressure relief module.

[0017] In one alternative embodiment, the pressure relief detection device further includes a test tank, and the pressure gauge is fixed to the side wall of the test tank.

[0018] In one alternative embodiment, the pressure setting range of the pressure relief detection device is 0.18 MPa to 0.2 MPa.

[0019] This invention installs a pressure relief detection device on a wine bottling machine. By jogging the wine bottling machine, the pressure data corresponding to the execution action of each station of the wine bottling machine can be detected. When the pressure data changes, it indicates that there is a fault. Then, based on the control parameters of the wine bottling machine and the data of the pressure gauge, the pressure relief module of the current execution action can be determined, thereby achieving the purpose of quickly finding faults and replacing spare parts, reducing the cost of fault diagnosis.

[0026] 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. It should be noted that, in the absence of conflict, the following embodiments can be combined.

[0027] The general beer production process is as follows: bottle cleaning, CO2 drying, primary vacuuming, secondary vacuuming, filling, depressurization, capping, and labeling. In beer production, bottling is the most crucial step in the entire process.

[0028] like Figure 2 As shown, the bottling machine includes a wine tank 1 at the top, an electromagnetic flowmeter valve 2 on the output pipe of the wine tank 1, and a CO2 inlet chamber 3 used in conjunction with the wine tank 1. During wine filling, the process is controlled by a slow filling valve 4, a fast filling valve 5, and a liquid inlet valve 6. During CO2 rinsing, the intake is controlled by the fast filling valve 5 and the CO2 displacement exhaust valve. Pressure relief is controlled by a pressure relief valve 8. The bottling machine also includes a centering device 7, which includes a cylinder, rollers, and a centering sleeve, capable of fixing the wine bottle or pressure relief detection device.

[0029] During the CO2 rinsing process, the inlet valve 6 is opened, allowing CO2 to enter the bottle through the CO2 inlet chamber for carbon dioxide rinsing. Simultaneously, the CO2 displacement exhaust valve 9 below the inlet valve 6 is opened, allowing the mixture of carbon dioxide and air to enter the exhaust chamber 10 and then be discharged outside the machine through a pipe. During the pressure preparation process: the CO2 displacement exhaust valve 9 below the inlet valve 6 is closed, cutting off the exhaust channel. The pressure inside the bottle gradually increases until it equals the filling pressure, reaching an isobaric state. This isobaric state is controlled by time.

[0030] During the filling process, when the internal pressure of the bottle is close to the pressure of the filling machine's storage tank 1, the inlet valve 6 opens, and the beer is filled into the bottle under gravity. The beer flows naturally down to the bottle neck and then down the bottle wall to the bottom. At this time, the beer in the storage tank 1 flows into the bottle, while the carbon dioxide in the bottle rises to the storage tank 1 to balance the pressure. The beer in the storage tank 1 and the carbon dioxide in the bottle exchange with each other. When the pressure inside the bottle equals the pressure inside the storage tank 1, filling automatically stops, thus establishing the finished beer filling level.

[0031] Bottled beer filling machines are the main equipment for beer packaging. A common problem is that the sealing valves are not sealing properly, which makes it impossible to achieve the required vacuuming and CO2 replenishment processes during the filling process. This allows air to enter the bottle, and the oxygen in the air dissolves into the beer, affecting the beer flavor. It is necessary to completely replace the sealing valves at multiple stations.

[0032] As can be seen from the above beer production process, the main processes affecting beer quality are the CO2 rinsing process, pressure preparation, slow filling, and fast filling. Therefore, the process can be graded for testing to quickly locate fault points. Since graded testing may involve multiple valves, the specific pressure relief module can be determined based on the parameters displayed on the beer bottling machine. Therefore, this invention provides a pressure relief detection method for beer bottling machines, specifically including the following steps.

[0033] Please see Figure 1 As shown, the pressure relief detection method for the wine bottling machine includes:

[0034] S100: Install the pressure relief detection device on the filling valve of the wine bottling machine.

[0035] See also Figure 2As shown, the pressure relief detection device 13 provided in this invention includes a test tank 11 and a pressure gauge 12, the pressure gauge 12 being fixed to the side wall of the test tank 11. The test tank 11 is made of 316 stainless steel, with a welded bottom seal. The pressure gauge 12 should be selected to be 1.0 MPa and installed at a distance from the bottom side wall of the test tank 11. The upper opening of the test tank 11 is fixedly connected to the filling position of the bottling machine. The pressure setting range of the pressure relief detection device 13 is 0.18 MPa to 0.2 MPa, matching the operating pressure setting of the bottling machine.

[0036] S200: The jogging control of the wine bottling machine enables the wine bottling machine to perform different working areas in stages, and observes the pressure gauge value of the pressure relief detection device.

[0037] As mentioned above, the main processes of the wine filling machine involve CO2 rinsing and wine filling, so the execution actions of the wine filling machine can be broken down into different working areas.

[0038] In one embodiment of the present invention, the current working area is determined by the operating parameters set by the wine bottling machine.

[0039] For example, the working process of the above-mentioned wine bottling machine is divided into six working areas based on carbon dioxide flushing time, carbon dioxide tank entry time, maximum wine dispensing time, pressure relief time, residual liquid spraying time, and segmented cleaning time. Please refer to Table 1 below for details.

[0040] Table 1

[0041] <![CDATA[CO2 purging time setting (ms)]]> time 1100 <![CDATA[CO2 tank entry time setting (ms)]]> time 1800 Maximum time to serve with alcohol (ms) time 15000 Depressurization time setting (ms) time 5000 Residual liquid flushing time setting (ms) time 100 Segmented cleaning interval setting (ms) time 2000

[0042] By referring to Table 1, the working area of ​​the jog-controlled wine bottling machine can be determined. The wine bottling machine executes according to the parameters set in Table 1 in sequence, so the currently executing working area can be determined by referring to the parameter table of the time for the wine bottling machine to execute different working areas in succession.

[0043] The CO2 rinsing time corresponds to the CO2 rinsing work area, the CO2 tank entry time corresponds to the CO2 tank entry work area, the maximum alcohol dispensing time corresponds to the alcohol dispensing work area, and so on, which can be divided into six work areas.

[0044] Based on the above description of the CO2 flushing and beer filling process, it can be seen that the liquid level gauge, electromagnetic flow meter valve, slow filling valve, fast filling valve, liquid inlet valve, pressure relief valve, and CO2 displacement exhaust valve of the beer filling machine may become points of failure. Each component, as a pressure relief module, will affect the beer quality due to pressure relief.

[0045] Therefore, the bottling machine can be jogged to operate in different work areas. The pressure gauge of the pressure relief detection device can be used to determine if a pressure relief fault has occurred in a particular work area based on whether the pressure fluctuates (i.e., whether the pressure value changes). If a pressure relief fault occurs in that work area, it can be determined that the components involved in that work area are faulty.

[0046] S300: If the pressure gauge value of the pressure relief detection device fluctuates within the currently executed work area, the pressure relief module of the wine bottling machine is determined based on the control parameters of the wine bottling machine and the currently executed work area.

[0047] In some embodiments, if the pressure gauge reading of the pressure relief detection device in the currently executed work area fluctuates compared to the control parameters of the bottling machine, it is determined that a pressure relief module exists in the currently executed work area. The control parameters displayed on the screen of the bottling machine typically include CO2 pressure, inlet pressure, inlet volume, and liquid level in the bottling tank, etc., specifically as follows: Figure 3 As shown.

[0048] In one implementation, the control parameter of the bottling machine is the carbon dioxide pressure (the CO2 pressure inside the bottling tank is consistent and can be viewed on the bottling machine's display screen), and this carbon dioxide pressure is a fixed value. Typically, the CO2 pressure setting range for the bottling machine is 0.18 MPa to 0.2 MPa. The pressure gauge reading of the pressure relief detection device should be equivalent to the CO2 pressure of the bottling machine. That is, if the CO2 pressure is set to 0.18 MPa, the pressure gauge reading of the pressure relief detection device should also be 0.18 MPa.

[0049] If the pressure gauge reading of the pressure relief detection device is less than the pressure value of the carbon dioxide, it is determined that a pressure relief module exists in the carbon dioxide flushing work area. For example, the pressure relief station involved in the currently executing work area is determined based on the low liquid level statistics of the bottling machine. If the pressure gauge reading differs from the pressure parameter displayed on the bottling machine's screen, it is determined that a pressure relief module exists at that pressure relief station.

[0050] For example, by jogging the filling machine and observing the pressure gauge change as the wine valve moves to the corresponding working area, if the current working area is the tank inlet area with a pressure set at 1.8 Bar, but the pressure drops to 1.2 Bar when moving to the CO2 tank inlet area, it indicates that a pressure relief module exists in the CO2 tank inlet area. Once it is determined that the seal in the CO2 tank inlet area may be damaged, the seal at the CO2 flushing station should be replaced immediately, using a spare part to replace the damaged seal; seals in other working areas do not need to be replaced, saving maintenance time and costs.

[0051] Furthermore, as can be seen from the above-described production process of the wine bottling machine, each working area may involve multiple pressure relief modules. The modules that can generate pressure relief in that working area can be directly replaced, or only individual sealing valves can be replaced. Usually, replacing the sealing valves can solve the pressure relief problem.

[0052] For example, in the carbon dioxide inlet working area, the pressure gauge value of the pressure relief detection device is lower than the pressure value set by the bottling machine. Fluctuations in the pressure gauge value of the pressure relief detection device are observed during the carbon dioxide flushing time. At least one of the fast filling valve, CO2 replacement exhaust valve, or liquid inlet valve involved in the carbon dioxide inlet process is a pressure relief module; the liquid inlet valve is usually replaced first.

[0053] For example, if the pressure gauge reading of the pressure relief detection device fluctuates during the carbon dioxide inlet time, the CO2 replacement exhaust valve or liquid inlet valve is identified as the pressure relief module; the liquid inlet valve is usually replaced first.

[0054] For example, if the pressure gauge reading of the pressure relief detection device fluctuates during the maximum time of alcohol dispensing, then at least one of the level gauge, electromagnetic flow meter valve, slow filling valve, fast filling valve, or inlet valve is identified as a pressure relief module; the inlet valve is usually replaced first.

[0055] For example, if the pressure gauge reading of the pressure relief detection device fluctuates during the pressure relief time, then the pressure relief valve is identified as a pressure relief module.

[0056] Furthermore, since the bottling machine can control dozens or even hundreds of bottling stations simultaneously, when a pressure leak occurs, it is necessary to identify one or more stations from among the many bottling stations where the pressure leak is occurring. After identifying the station, the pressure leak detection device is installed at that station, and then the aforementioned pressure leak detection method is executed. Here, a bottling station can be understood as corresponding to the filling of a single bottle; the work area can be understood as multiple control processes for filling a single bottle.

[0057] In an embodiment of the present invention, the pressure relief station involved in the currently executed work area is determined based on the low liquid level statistics of the bottling machine. If the pressure gauge value of the pressure relief detection device differs from the pressure parameters displayed on the screen of the bottling machine, it is determined that the seal associated with the currently executed work area has a pressure relief module.

[0058] The process of determining the pressure relief stations involved in the current work area based on low liquid level statistics from the filling machine involves obtaining liquid level statistics for each filling station from the filling machine and then screening out filling stations with liquid levels below or frequently below the threshold. Liquid levels below the threshold indicate a pressure relief problem, so pressure relief detection can be performed on the filling stations screened by the filling machine. This method is more efficient than screening each station individually on the production line.

[0059] like Figure 4 As shown, the control interface of the bottling machine can display data on abnormal liquid levels at the bottling station. The data indicates that the liquid level at valve number 34 (bottling station) is frequently abnormal, potentially indicating a pressure leak. The pressure leak detection device should be used to check for pressure leaks. If a pressure leak is found, the pressure leak module should be located in the affected area and replaced with a spare part promptly.

[0060] Therefore, this invention installs a pressure relief detection device on the bottling machine. By jogging the bottling machine, the pressure data corresponding to the execution action of each station of the bottling machine can be detected. When the pressure data changes, it indicates that there is a fault. Then, based on the control parameters of the bottling machine and the data of the pressure gauge, the pressure relief module of the current execution action can be determined, thereby achieving the purpose of quickly finding faults and replacing spare parts, reducing the cost of fault diagnosis.
