Technical Field

[0001] The invention relates to the field of pressure relief detection of wine filling machines, and in particular to a pressure relief detection method for wine filling machines. Background Art

[0002] During the canned beer filling process, if beer is bubbling out of the valve, the liquid level is unstable, or TPO (the sum of the oxygen content in the beer liquid and the oxygen content in the headspace) is unstable, the machine needs to be stopped every time to check the level gauge, control solenoid valve, and seal of the valve. If the fault point cannot be determined, the spare parts must be replaced in order and checked one by one. Such troubleshooting leads to long equipment downtime, serious efficiency loss, high spare parts replacement cost, and serious waste. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a pressure relief detection method for a wine filling machine to solve the problems of high cost of troubleshooting and replacement of spare parts.

[0004] The present invention provides a pressure relief detection method for a wine filling machine, comprising the following steps:

[0005] Installing a pressure relief detection device on the filling valve of the wine filling machine, wherein the pressure relief detection device includes a pressure gauge;

[0006] Inching control of the wine filling machine so that the wine filling machine executes different working areas in batches, and observing the pressure gauge value of the pressure relief detection device;

[0007] If the value of the pressure gauge of the pressure relief detection device fluctuates within the currently executed working area, the pressure relief module of the wine filling machine is determined according to the control parameters of the wine filling machine and the currently executed working area; wherein the currently executed working area is determined by the time comparison parameter table of the wine filling machine executing different working areas in batches.

[0008] In an optional implementation, the currently executed working area is determined by a time comparison parameter table of the wine filling machine executing different working areas in batches, including:

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

[0010] In an optional implementation, if the value of the pressure gauge of the pressure relief detection device fluctuates during the carbon dioxide flushing time, it is determined that at least one of the fast filling valve, the CO2 replacement exhaust valve, or the liquid inlet valve is a pressure relief module.

[0011] In an optional implementation, if the value of the pressure gauge of the pressure relief detection device fluctuates during the time when the carbon dioxide enters the tank, it is determined that the CO2 replacement exhaust valve or the liquid inlet valve is a pressure relief module.

[0012] In an optional embodiment, if the value of the pressure gauge of the pressure relief detection device fluctuates within the maximum drinking time, it is determined that at least one of the liquid level meter, electromagnetic flow meter valve, slow filling valve, fast filling valve or liquid inlet valve is a pressure relief module.

[0013] In an optional implementation, if the value of the pressure gauge of the pressure relief detection device in the currently executed working area fluctuates compared with the control parameter of the wine filling machine, it is determined that a pressure relief module exists in the currently executed working area.

[0014] In an optional embodiment, the control parameter of the wine filling machine is the pressure value of carbon dioxide, and the pressure value of carbon dioxide is a fixed value. If the value of the pressure gauge 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.

If there is a difference between the pressure gauge value and the pressure parameter displayed on the screen of the wine filling machine, it is determined that a pressure relief module exists in the seal associated with the currently executed working area.

[0017] In an optional implementation, the pressure relief detection device further includes a test tank, and the pressure gauge is fixed on a side wall of the test tank.

[0018] In an optional implementation, the pressure setting range of the pressure relief detection device is 0.18 MPa to 0.2 MPa.

[0019] The present invention installs a pressure relief detection device on a wine filling machine. The pressure data corresponding to the execution action of each station of the wine filling machine can be detected by inching control of the wine filling machine. When the pressure data changes, it indicates that a fault exists.

DETAILED DESCRIPTION

[0026] 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 those skilled in the art without creative work are within the scope of protection of the present invention. It should be noted that the following embodiments can be combined without conflict.

[0027] The general beer production process is: bottle cleaning, drying with CO2, primary vacuuming, secondary vacuuming, bottle filling, pressure relief, capping, labeling. In beer production, beer filling is the most important part of the entire production process.

[0028] like Figure 2 As shown, the wine filling machine includes a wine tank 1 at the top, an electromagnetic flowmeter valve 2 is provided on the output pipe of the wine tank 1, and a CO2 air inlet chamber 3 used in conjunction with the wine tank 1; the wine filling is controlled by a slow filling valve 4, a fast filling valve 5, and a liquid inlet valve 6; during the CO2 flushing process, the air intake is controlled by the fast filling valve 5 and the CO2 replacement exhaust valve. When the pressure is released, it is controlled by the pressure relief valve 8. The wine filling machine also includes a centering device 7, which includes a cylinder, a roller, and a centering sleeve, etc., which can fix the wine bottle or the pressure relief detection device.

[0029] During the CO2 flushing process, the liquid inlet valve 6 is opened so that CO2 enters the wine bottle through the CO2 inlet chamber to perform carbon dioxide flushing. At the same time, the CO2 replacement exhaust valve 9 at the bottom of the liquid inlet valve 6 is opened, and the mixed gas of carbon dioxide and air enters the discharge chamber 10 through the CO2 replacement exhaust valve 9, and then is discharged to the outside of the machine through the pipeline. During the pressure preparation process: the CO2 replacement exhaust valve 9 at the bottom of the liquid inlet valve 6 is closed, the discharge channel is cut off, the pressure in the wine bottle gradually increases, and finally equals the filling pressure to reach an isobaric state, which is controlled by time.

[0030] During the filling process, when the internal pressure of the wine bottle is close to the pressure of the wine storage tank 1 of the filling machine, the liquid inlet valve 6 opens, and the beer liquid is filled into the wine bottle under the action of gravity. The beer liquid naturally flows down to the bottle mouth and flows to the bottom of the bottle along the bottle wall; at this time, the beer liquid in the wine tank 1 flows into the wine bottle, and the carbon dioxide in the wine bottle rises to the wine tank 1 to balance the pressure. The beer liquid in the wine tank 1 and the carbon dioxide in the wine bottle are replaced with each other. When the pressure in the bottle is equal to the pressure in the wine tank 1, the beer filling stops automatically, and the filling liquid level of the finished beer is formed.

[0031] Bottled beer filling machines are the main equipment for beer packaging. A common problem is that the sealing valve is not sealed enough, resulting in the vacuum and CO2 replenishment processes failing to meet the requirements during the filling process. This causes air to enter the bottle, and the oxygen in the air dissolves into the beer, affecting the flavor of the beer. It is necessary to completely replace the sealing valves at multiple workstations.

[0032] It can be seen from the above beer production process that the process that affects the quality of beer is mainly the CO2 flushing process, pressure preparation, slow filling and fast filling process. Therefore, the process can be graded and tested to quickly locate the fault point. The graded detection may involve multiple valve bodies, so the specific pressure relief module can be determined based on the display screen parameters of the beer filling machine. Therefore, the present invention provides a pressure relief detection method for a beer filling machine, which specifically includes the following steps.

[0033] See also Figure 1 As shown, the pressure relief detection method for a wine filling machine includes:

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

[0035] See also Figure 2As shown, the pressure relief detection device 13 provided in the present invention includes a test tank 11 and a pressure gauge 12, and the pressure gauge 12 is fixed on the side wall of the test tank 11. The material of the test tank 11 is stainless steel 316, and the bottom seal is welded. The pressure gauge 12 should be selected as 1.0MPa and is installed at a position away 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 wine filling machine. The pressure setting range of the pressure relief detection device 13 is 0.18MPa to 0.2Mpa, matching the operating pressure setting of the wine filling machine.

[0036] S200: Inching control of the wine filling machine so that the wine filling machine executes different working areas in batches, and observing the pressure gauge value of the pressure relief detection device.

[0037] As mentioned above, the main process of the wine filling machine involves CO2 flushing and wine filling, so the execution actions of the above wine filling machine can be decomposed into different working areas.

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

[0039] For example, the working process of the wine filling machine is divided into six working areas according to the carbon dioxide flushing time, carbon dioxide tank entry time, maximum wine filling time, pressure relief time, residual liquid spraying time, and segmented cleaning time. For details, please refer to the following Table 1.

[0040] Table 1

[0041] Operation parameter setting unit value <![CDATA[CO2 flushing time setting (ms)]]> time 1100 <![CDATA[CO2 inlet tank time setting (ms)]]> time 1800 Maximum time setting for serving wine (ms) time 15000 Pressure relief time setting (ms) time 5000 Residual liquid spraying time setting (ms) time 100 Segment cleaning interval setting (ms) time 2000

[0042] By comparing Table 1, the working area of ​​the inching control wine filling machine can be known. The wine filling machine is executed according to the parameters set in Table 1 in sequence, so the currently executed working area can be determined by the time comparison parameter table of the wine filling machine executing different working areas in batches.

[0043] The CO2 flushing time corresponds to the CO2 flushing working area, the CO2 tank entering time corresponds to the CO2 tank entering working area, the maximum wine serving time corresponds to the wine serving working area, and so on. It can be divided into six working areas.

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

[0045] Therefore, the wine filling machine can be controlled to execute different working areas by inching, and whether a pressure relief failure occurs in a certain working area can be judged according to whether the pressure gauge of the pressure relief detection device fluctuates (i.e., whether the pressure value changes). If a pressure relief failure occurs in the working area, it can be judged that there is a fault in the components involved in the working area.

[0046] S300: If the value of the pressure gauge of the pressure relief detection device fluctuates in the currently executed working area, the pressure relief module of the wine filling machine is determined according to the control parameters of the wine filling machine and the currently executed working area.

[0047] In some embodiments, if the value of the pressure gauge of the pressure relief detection device in the currently executed working area fluctuates compared with the control parameters of the wine filling machine, it is determined that there is a pressure relief module in the currently executed working area. The control parameters displayed on the screen of the wine filling machine generally include CO2 pressure, wine inlet pressure, wine inlet volume, wine tank liquid level and other parameters, such as Figure 3 shown.

[0048] As an implementation mode, the control parameter of the wine filling machine is the pressure value of carbon dioxide (the CO2 pressure in the wine tank is consistent and can be checked through the display screen of the wine filling machine), and the pressure value of carbon dioxide is a fixed value. Usually, the CO2 pressure setting range of the wine filling machine is 0.18MPa to 0.2MPa. The value of the pressure gauge of the pressure relief detection device should be equivalent to the CO2 pressure of the wine filling machine. That is, if the CO2 pressure is set to 0.18MPa, the value of the pressure gauge of the pressure relief detection device should also be 0.18MPa.

[0049] If the value of the pressure gauge of the pressure relief detection device is less than the pressure value of the carbon dioxide, it is determined that there is a pressure relief module in the carbon dioxide flushing work area. For example, the pressure relief station involved in the currently executed work area is determined based on the low liquid level statistics of the wine filling machine. If there is a difference between the value of the pressure gauge and the pressure parameter displayed on the screen of the wine filling machine, it is determined that there is a pressure relief module in the pressure relief station.

[0050] For example, start the filling machine and observe that the wine valve of the filling machine runs to the corresponding working area, and the pressure gauge will change. For example, if the currently executed working area is the tank inlet area, and the pressure is set at 1.8 Bar, but when it runs to the CO2 tank inlet area, the pressure changes to 1.2 Bar, then it is determined that there is a pressure relief module in the carbon dioxide tank inlet working area. After determining that the seal of the CO2 tank inlet area may be damaged, immediately replace the seal of the CO2 flushing station and use spare parts to replace the damaged seal; the seals of other working areas do not need to be replaced, saving maintenance time and maintenance costs.

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

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

[0053] For example, if the value of the pressure gauge of the pressure relief detection device fluctuates during the time when carbon dioxide enters the tank, it is determined that the CO2 replacement exhaust valve or the liquid inlet valve is the pressure relief module; the liquid inlet valve is usually replaced first.

[0054] For example, if the value of the pressure gauge of the pressure relief detection device fluctuates within the maximum drinking time, it is determined that at least one of the liquid level meter, electromagnetic flow meter valve, slow filling valve, fast filling valve or liquid inlet valve is a pressure relief module; the liquid inlet valve is usually replaced first.

[0055] For example, if the value of the pressure gauge of the pressure relief detection device fluctuates during the pressure relief time, it is determined that the pressure relief valve is a pressure relief module.

[0056] Furthermore, since the wine filling machine can control dozens or hundreds of wine filling stations at the same time, when pressure relief occurs, it is necessary to determine which one or several stations have pressure relief problems from the numerous wine filling stations. After the pressure relief station is determined, the pressure relief detection device is installed on the pressure relief station, and then the pressure relief detection method is performed. The wine filling station can be understood as corresponding to the filling of a wine bottle; the working area can be understood as multiple control processes for filling a wine 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 statistical data of the wine filling machine. If there is a difference between the pressure gauge value of the pressure relief detection device and the pressure parameter displayed on the screen of the wine filling machine, it is determined that a pressure relief module exists in the seal associated with the currently executed work area.

[0058] Among them, the pressure relief stations involved in the currently executed work area are determined based on the low liquid level statistics of the wine filling machine. The liquid level statistics of each wine filling station are obtained through the filling machine, and the wine filling stations with liquid levels below the threshold or frequently below the threshold are screened out. The liquid level below the threshold indicates that there is a pressure relief problem, so the pressure relief test can be performed based on the wine filling stations screened by the wine filling machine. Compared with screening one by one on the production line, it is more efficient.

[0059] like Figure 4 As shown, the data of abnormal liquid level at the filling station can be viewed on the control interface of the wine filling machine. It can be seen from the data that the liquid level of valve No. 34 (wine filling station) is frequently abnormal, and there may be a pressure relief problem. The pressure relief detection device is used to detect whether there is a pressure relief problem. If there is a pressure relief problem, the pressure relief module is determined in the pressure relief working area and the spare parts can be replaced in time.

[0060] Therefore, the present invention installs a pressure relief detection device on the wine filling machine. By inching control of the wine filling machine, the pressure data corresponding to the execution action of each station of the wine filling machine can be detected. When the pressure data changes, it means that there is a fault. Then, the pressure relief module that exists in the current execution action can be determined based on the control parameters of the wine filling machine and the data of the pressure gauge, thereby achieving the purpose of quickly finding the fault and replacing spare parts, reducing the cost of troubleshooting.
