Description

Technical Field

[0001] This invention relates to the field of filling technology, specifically to a visual, high-precision isobaric beer filling machine. Background Technology

[0002] As living standards improve, people are seeking fresher and better-tasting drinking experiences. Beer, as one of the most popular beverages, has a large customer base. To meet customers' higher drinking requirements, freshly brewed beer is gradually entering commercial operation. To realize freshly brewed beer, automatic bottling equipment for freshly brewed beer has emerged.

[0003] Patent application number CN202121000759.1 discloses an integrated isobaric beer filling machine. This machine employs an automatic bottle dropping, manual bottle placement, and automatic filling mode, allowing users to conveniently and quickly obtain a rich and unique-tasting fresh beer. However, during the filling process, when venting carbon dioxide gas, the emitted carbon dioxide gas contains beer mist. This beer mist is very viscous, causing the exhaust valve to easily become stuck. Furthermore, the exhaust port at the end of the exhaust pipe has a very small diameter, making it prone to blockage. Consequently, after prolonged use, the equipment cannot properly exhaust gas, and it cannot dispense beer. Summary of the Invention

[0004] In order to overcome the problems of the exhaust valve being easily stuck and the exhaust hole being easily blocked after long-term use in the existing isobaric beer filling machine, which leads to the inability to properly exhaust and dispense beer, the present invention provides a visualized high-precision isobaric beer filling machine.

[0005] The technical solution of this invention is as follows:

[0006] A high-precision, visually-oriented isobaric beer filling machine includes several isobaric filling mechanisms housed within a cabinet for filling beer. Each isobaric filling mechanism includes a filling head, a lifting assembly fixed to the filling head, and a moving assembly located below the filling head. A cup is placed on or fitted onto the moving assembly. The lifting end of the lifting assembly is connected to the moving assembly and drives the moving assembly to rise and fall.

[0007] The isobaric filling mechanism further includes a dual waste liquid venting assembly, which includes a primary waste liquid tank for gas-liquid separation and a secondary waste liquid tank for gas filtration.

[0010] According to the above-described visualization high-precision isobaric beer filling machine, the air inlet and exhaust outlet of the secondary waste liquid tank are both located at its top. The secondary waste liquid tank is equipped with a secondary waste liquid tank pipe inside. The upper end of the secondary waste liquid tank pipe is connected to the air inlet of the secondary waste liquid tank, and the lower end of the secondary waste liquid tank pipe extends into the lower end of the interior of the secondary waste liquid tank pipe. The bottom of the secondary waste liquid tank is equipped with a drain outlet, which is connected to a secondary drain valve.

[0011] According to the above-described visualization high-precision isobaric beer filling machine, a waste liquid tank connecting valve is installed on the pipe connecting the exhaust port of the primary waste liquid tank and the air inlet of the secondary waste liquid tank.

[0012] According to the above-described visualization high-precision isobaric beer filling machine, the dual waste liquid exhaust assembly also includes a waste liquid tank bracket and a waste liquid weighing sensor. The primary waste liquid tank and the secondary waste liquid tank are both fixed on the waste liquid tank bracket. The fixed end of the waste liquid weighing sensor is fixed to the waste liquid tank bracket and the fixed end of the waste liquid weighing sensor is fixed to the cabinet.

[0013] Furthermore, the waste liquid weighing sensor is a cantilever beam weighing sensor.

[0014] Furthermore, the waste liquid tank support includes a first fixing ring fixed to the primary waste liquid tank, a second fixing ring fixed to the secondary waste liquid tank, and a fixing plate fixed to the fixing end of the waste liquid weighing sensor. A first connecting plate is provided between the first fixing ring and the second fixing ring, and a second connecting plate is provided between the second fixing ring and the fixing plate.

[0015] According to the above-described visualization high-precision isobaric beer filling machine, the upper end of the filling head is provided with a first interface for connecting to a primary waste liquid tank and a second interface for connecting a beer tank, a carbon dioxide tank, and a clear water tank. The lower end of the filling head is provided with an exhaust and liquid discharge port and a liquid outlet. The exhaust and liquid discharge port of the filling head is connected to the first interface, and the liquid outlet of the filling head is connected to the second interface.

[0016] Furthermore, a pre-pressure solenoid valve and a pressure sensor are installed on the pipe connecting the second interface and the carbon dioxide tank, a wine inlet solenoid valve is installed on the pipe connecting the second interface and the wine tank, and a water inlet solenoid valve is installed on the pipe connecting the second interface and the clear water tank.

The lower part of the cabinet is equipped with a cooling cabinet, which contains beer tanks and water barrels.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] The high-precision, visually-oriented isobaric beer filling machine provided by this invention features a primary waste liquid tank for gas-liquid separation and a secondary waste liquid tank for gas filtration. The secondary waste liquid tank stores clean water, allowing carbon dioxide gas discharged from the primary waste liquid tank to pass through the clean water before exiting through the exhaust port of the secondary waste liquid tank. The clean water in the secondary waste liquid tank filters the incoming carbon dioxide gas, dissolving the beer mist within it. This prevents the discharged carbon dioxide gas from carrying beer mist through the exhaust valve and the exhaust port at the end of the exhaust pipe, ensuring normal exhaust and beer dispensing even after prolonged use. The primary waste liquid tank also prevents spilled beer from entering the secondary waste liquid tank, thus avoiding interference with the filtration function of the clean water within the secondary waste liquid tank.

[0033] Please see Figures 1 to 7This embodiment provides a visual high-precision isobaric beer filling machine, including several isobaric filling mechanisms 2 set in the cabinet 1 for filling beer. The isobaric filling mechanism 2 includes a filling head 21, a lifting component 22 fixed on the filling head 21, a moving component 23 located below the filling head 21, and a dual waste liquid exhaust component 24. The cup 3 is placed on or fitted on the moving component 23. The lifting end of the lifting component 22 is connected to the moving component 23 and drives the moving component 23 to rise and fall. The dual waste liquid exhaust assembly 24 includes a primary waste liquid tank 241 for gas-liquid separation and a secondary waste liquid tank 242 for gas filtration. The air and liquid inlets of the primary waste liquid tank 241 are connected to the exhaust and liquid outlets of the filling head 21. The exhaust outlet of the primary waste liquid tank 241 is connected to the air inlet of the secondary waste liquid tank 242. The exhaust outlet of the secondary waste liquid tank 242 is connected to the exhaust valve 243. The secondary waste liquid tank 242 contains clean water. The gas (carbon dioxide) discharged from the primary waste liquid tank 241 passes through the clean water and is discharged from the exhaust outlet of the secondary waste liquid tank 242. The clean water in the secondary waste liquid tank 242 can filter the incoming gas, dissolving impurities (such as alcohol mist) in the gas. This prevents the discharged carbon dioxide gas from carrying alcohol mist through the exhaust valve 243 and the exhaust outlet at the end of the exhaust pipe, ensuring that the equipment can still exhaust and dispense alcohol normally after long-term use. Since the overflowing wine may enter the exhaust and drainage port of the filling head 21 after filling, in order to prevent the wine from entering the secondary waste liquid tank 242 and affecting the filtration of the clean water, a primary waste liquid tank 241 needs to be set up before the secondary waste liquid tank 242 for gas-liquid separation.

[0034] Please see Figure 3 , Figure 5 , Figure 6The air inlet and liquid inlet, as well as the exhaust outlet, of the primary waste liquid tank 241 are both located at its top. Inside the primary waste liquid tank 241, there is a primary waste liquid tank pipe 2411. The upper end of the primary waste liquid tank pipe 2411 is connected to the air inlet and liquid inlet of the primary waste liquid tank 241, and the lower end of the primary waste liquid tank pipe 2411 extends into its lower interior, so that the gas and liquid entering from the air inlet and liquid inlet of the primary waste liquid tank 241 are separated within the primary waste liquid tank pipe 2411. The separated gas enters the air inlet of the secondary waste liquid tank 242 through the exhaust outlet at its top. A drain outlet is also provided at the bottom of the primary waste liquid tank 241, which is connected to a primary drain valve 244. The primary drain valve 244 is used to control the discharge of the liquid from the primary waste liquid tank 241. The air inlet and exhaust outlet of the secondary waste liquid tank 242 are both located at its top. A secondary waste liquid tank pipe 2421 is installed inside the secondary waste liquid tank 242. The upper end of the secondary waste liquid tank pipe 2421 is connected to the air inlet of the secondary waste liquid tank 242, and the lower end of the secondary waste liquid tank pipe 2421 extends into the lower part of the secondary waste liquid tank pipe 2421. The water level is higher than the air outlet of the secondary waste liquid tank pipe 2421, so that the gas entering the secondary waste liquid tank pipe 2421 is passed through the clean water, dissolving impurities (such as alcohol mist) in the gas. A drain outlet is also provided at the bottom of the secondary waste liquid tank 242, which is connected to a secondary drain valve 245. The secondary drain valve 245 is used to control the discharge of clean water from the secondary waste liquid tank 242. In addition, a waste liquid tank connecting valve 246 is installed on the pipe connecting the exhaust port of the primary waste liquid tank 241 and the air inlet of the secondary waste liquid tank 242 to control the connection between the primary waste liquid tank 241 and the secondary waste liquid tank 242.

[0035] Please see Figure 5 The dual waste liquid venting assembly 24 also includes a waste liquid tank bracket 247 and a waste liquid weighing sensor 248. The waste liquid weighing sensor 248 is a cantilever beam weighing sensor, which has high detection accuracy and is not affected by the external environment. The primary waste liquid tank 241 and the secondary waste liquid tank 242 are both fixed on the waste liquid tank bracket 247. The fixed end of the waste liquid weighing sensor 248 is fixed to the waste liquid tank bracket 247 and the cabinet 1. The waste liquid weighing sensor 248 is used to collect the weight of the primary waste liquid tank 241 and the secondary waste liquid tank 242 in real time, and to determine the weight of the waste liquid in the primary waste liquid tank 241 based on the weight. When the weight of the waste liquid reaches the set value, the primary drain valve 244 is opened to drain the waste liquid in the primary waste liquid tank 241, preventing the waste liquid in the primary waste liquid tank 241 from overflowing and entering the secondary waste liquid tank 242.

[0036] Please see Figure 7Specifically, the waste liquid tank bracket 247 includes a first fixing ring 2471 fixed to the primary waste liquid tank 241, a second fixing ring 2472 fixed to the secondary waste liquid tank 242, and a fixing plate 2473 fixed to the fixing end of the waste liquid weighing sensor 248. A first connecting plate 2474 is provided between the first fixing ring 2471 and the second fixing ring 2472, and a second connecting plate 2475 is provided between the second fixing ring 2472 and the fixing plate 2473. The first fixing ring 2471 is fixed to the edge of the tank cover of the primary waste liquid tank 241 by a fastener (such as a screw), the second fixing ring 2472 is fixed to the edge of the tank cover of the secondary waste liquid tank 242 by a fastener (such as a screw), and the fixing plate 2473 is fixed to the fixing end of the waste liquid weighing sensor 248 by a fastener (such as a screw).

[0037] Please see Figure 3 , Figure 4 The upper end of the filling head 21 is provided with a first interface 211 for connecting to the primary waste liquid tank 241 and a second interface 212 for connecting the wine tank 4, the carbon dioxide tank, and the clear water tank 5. The lower end of the filling head 21 is provided with an exhaust port and a liquid outlet. The exhaust port of the filling head 21 is connected to the first interface 211, and the liquid outlet of the filling head 21 is connected to the second interface 212. When the mouth of the cup 3 is pushed against the filling sealing plate of the filling head 21 by the lifting component 22, it can surround the exhaust port and the liquid outlet of the filling head 21 inside the mouth of the cup to prevent air leakage at the bottle mouth during the filling process and generate a large amount of foam. The pipe connecting the second interface 212 and the carbon dioxide tank is provided with a pre-pressure solenoid valve 25 and a pressure sensor. The pre-pressure solenoid valve 25 is used to control the opening and closing of the pipe between the second interface 212 and the carbon dioxide tank to control the filling of carbon dioxide gas into the cup 3; the pressure sensor is used to detect the pressure of the carbon dioxide gas filling the cup 3. A wine inlet solenoid valve 26 is installed on the pipe connecting the second interface 212 and the wine tank 4. The wine inlet solenoid valve 26 is used to control the opening and closing of the pipe between the second interface 212 and the wine tank 4, so that the wine can enter the cup 3. A water inlet solenoid valve 27 is installed on the pipe connecting the second interface 212 and the clean water tank 5. The water inlet solenoid valve 27 is used to control the opening and closing of the pipe between the second interface 212 and the clean water tank 5, so as to clean the filling pipe.

[0038] Please see Figure 3 , Figure 4The isobaric filling mechanism 2 also includes a weighing base plate 28 and a filling weighing sensor 29. The force-bearing ends of the lifting assembly 22 and the filling weighing sensor 29 are both fixed to the weighing base plate 28, and the fixed end of the filling weighing sensor 29 is fixed to the cabinet 1. By suspending the entire isobaric filling mechanism 2 on the filling weighing sensor 29, during use, the cup 3 is placed on the moving assembly 23, and the cup mouth of the cup 3 is connected to the filling head 21 through the lifting assembly 22, thereby achieving the purpose of synchronous weighing of the cup 3 during filling. In addition, since the filling weighing sensor 29 adopts a cantilever beam weighing sensor with high detection accuracy and is not affected by the external environment, it achieves precise control of the liquid flow rate and velocity, avoiding the problem of wasting a large amount of wine during the machine debugging stage.

[0039] Please see Figure 1 , Figure 2 The upper part of cabinet 1 is equipped with a filling cabinet 11 and a cup cabinet 12. The isobaric filling mechanism 2 is located inside the filling cabinet 11. The front of the filling cabinet 11 is also equipped with an operation display screen 111 for customers to order and pay. The cup cabinet 12 is equipped with several shelves 121 for storing cups 3. Both the filling cabinet 11 and the cup cabinet 12 have separate transparent cabinet doors 112, allowing customers to see the remaining empty cups 3 and the filling process without opening the cabinet doors. The lower part of cabinet 1 is equipped with a cooling cabinet 13, which stores wine tanks 4 and water tanks 5. The cooling cabinet 13 is equipped with a cooling system 6 to maintain the internal temperature of the cooling cabinet 13 at 0-5 degrees Celsius.

[0040] In this embodiment, an Android system is also included. The Android system is connected to the control system of the filling machine, and it is also connected to a payment system, an advertising system, and a back-end management system. The payment system provides consumers with various payment methods; the advertising system displays and disseminates image or video advertisements to users; and the back-end management system supports back-end management, such as payment management, equipment management, personnel management, and log management. The Android system sends signals to the control system, which then controls the operation of each mechanism, enabling them to cooperate and produce fresh, chilled beverages.

[0041] Working principle:

[0042] 1. When dispensing wine, take out a cup 3 from the cup cabinet 12 and place or put the cup 3 on the moving component 23. When the mouth of the cup 3 is pushed against the filling sealing plate of the filling head 21 by the lifting component 22, the cup 3 is sealed.

[0043] 2. Open the pre-pressure solenoid valve 25 and fill the cup 3 with carbon dioxide gas at a pressure of 0.15MPa. After the pressure sensor detects that the pressure value has reached the working pressure, close the pre-pressure solenoid valve 25.

[0044] 3. Open one of the wine inlet solenoid valves 26, and the wine flows from the top connector of the distributor of wine tank 4 into the corresponding wine inlet solenoid valve 26.

[0045] 4. Open the waste liquid tank connecting valve 246 and the exhaust valve 243. The carbon dioxide gas in cup 3 enters the primary waste liquid tank 241, and then enters the secondary waste liquid tank 242 containing clean water through the waste liquid tank connecting valve 246. Since there is clean water in the secondary waste liquid tank 242, it can filter the incoming carbon dioxide gas, dissolving impurities (such as alcohol mist) in the carbon dioxide gas in the water. The filtered carbon dioxide gas is then discharged from the exhaust valve 243 at the top of the secondary waste liquid tank 242. After the carbon dioxide gas is discharged, the air pressure in cup 3 drops. Due to the air pressure difference between the wine tank 4 and cup 3, the wine flows out through the distributor and flows through the corresponding wine inlet solenoid valve 26 and filling head 21 into cup 3.

[0046] 5. After the weight of the wine reaches the set value by the weight collected by the filling weighing sensor 29, close the corresponding wine inlet solenoid valve 26 and wait for the pressure to be released.

[0047] 6. After the pressure is released, the lifting component 22 lowers the cup 3, and the wine is poured.
