Description

Technical Field

[0010]

[0001] The present invention relates to the technical field of automated filling, and particularly to an isobaric automatic filling device for canned beer with miniaturization and high precision. Background Art

[0002] Beer is one of the oldest alcoholic beverages of mankind and is the third most consumed beverage in the world after water and tea. Beer was introduced into China in the early 20th century and is an imported liquor type. Beer is translated into Chinese as "啤" according to the English word "Beer" and has been called "beer" ever since. Beer is a low-alcohol beverage containing carbon dioxide brewed mainly from malt, hops, and water through yeast fermentation and is known as "liquid bread".

[0003] Existing canned beer production lines are mainly designed for large breweries, requiring a very high filling speed. Therefore, the structural design is complex and the floor area is very large; and it is non-isobaric filling. Each production requires trial runs, and it needs to be adjusted to appropriate temperatures, speeds, and beer discharging times to achieve normal filling effects. This process will result in a large amount of wasted beer liquid, leading to high usage costs. The amount of beer liquid filled in a single large-scale beer filling is over a hundred tons, and the consumption of one or half a ton of beer liquid during trial runs can be ignored when averaged over the total filling volume. However, the total amount of beer filled by small and medium-sized breweries may only be half a ton or one ton each time. Therefore, small and medium-sized beer factories cannot use such filling equipment. Summary of the Invention

[0079] Please see Figure 1This embodiment provides a miniaturized, high-precision, isobaric automatic beer filling equipment, including a frame 1, an upper conveyor belt 2, a carbon dioxide blowing mechanism 3, a first transfer mechanism, a filling mechanism 4, a second transfer mechanism, a can cap dispensing mechanism 5, a sealing machine 6, and a cleaning mechanism 7. The frame 1 is equipped with a feeding station, a blowing station, a filling station, a transfer station, a capping station, a sealing station, a cleaning station, and a discharging station. The upper conveyor belt 2 is installed at the feeding station and is used to receive unsealed beer cans and transport them to the blowing station. Unsealed beer cans can be placed onto the upper conveyor belt 2 manually or by a robotic arm. The carbon dioxide blowing mechanism 3 is installed at the blowing station and is used to blow carbon dioxide gas into the beer cans at the blowing station to remove oxygen from the cans, ensuring minimal contact between the beer and oxygen during filling. The first transfer mechanism is installed on the frame 1. This mechanism moves the blown beer cans to the filling station and the filled beer cans to the transfer station. The filling mechanism 4 is installed at the filling station. It performs isobaric filling of the beer cans at the filling station. This isobaric filling method not only speeds up the filling process but also ensures product quality, resulting in a better taste, and avoids excessive foaming during filling. The second transfer mechanism is installed at the transfer station. It sequentially transports the filled beer cans at the transfer station to the capping station, sealing station, and unloading station. The cap dispensing mechanism 5 is installed at the capping station. It dispenses stored caps and presses them onto the mouths of the beer cans at the capping station, allowing both cap dispensing and pressing to be completed in one station. This reduces space requirements and effectively increases production speed. A sealing machine 6 is installed at the sealing station and is used to seal beer cans located at the sealing station. A cleaning mechanism 7 is installed at the cleaning station and is used to rinse the sealed beer cans located at the cleaning station. Since beer may overflow from the can opening during filling, post-filling movement, capping, and sealing, it is necessary to rinse the sealed beer cans to remove the overflowing beer and keep the product clean.

[0080] Please see Figure 2In one embodiment, the first transfer mechanism includes a transfer platform 8, left and right push plate mechanisms 9, and front and rear push plate mechanisms 10. The transfer platform 8 is installed behind the filling station, and the transfer station is installed in front of the filling station. The left and right push plate mechanisms 9 are installed on the side of the transfer platform 8 near the carbon dioxide blowing mechanism 3, and are used to push the blown beer cans onto the transfer platform 8. The front and rear push plate mechanisms 10 are installed behind the transfer platform 8, and are used to push the beer cans on the transfer platform 8 to the filling station and to push the filled beer cans to the transfer station. The first transfer mechanism described above has a reasonable and compact structural design, and can stably and quickly move the blown beer cans to the filling station and the filled beer cans to the transfer station.

[0081] Please see Figure 2 Specifically, the left and right push plate mechanism 9 includes left and right push plates 901 and left and right moving modules 902 for driving the left and right push plates 901 to move left and right. The left and right push plates 901 are provided with multiple first arc-shaped limiting grooves 9011 arranged side by side and matching the side contour of the beer can. The depth of the first arc-shaped limiting grooves 9011 is greater than the radius of the beer can, so as to ensure that when the left and right push plates 901 drive the beer can to move left and right, the beer can will not be dislodged from the first arc-shaped limiting grooves 9011, and multiple beer cans can be moved left and right at the same time to speed up the production speed.

[0082] Please see Figure 2 Specifically, the front and rear push plate mechanism 10 includes a front and rear push plate 1001 and a front and rear moving module 1002 for driving the front and rear push plate 1001 to move back and forth. The front and rear push plate 1001 is provided with a plurality of second arc-shaped limiting grooves 10011 arranged side by side and matching the side contour of the beer can. The depth of the second arc-shaped limiting grooves 10011 is less than the radius of the beer can, so as to ensure that the front and rear push plate 1001 can stably drive the beer can to move back and forth.

[0083] Please see Figure 1 In one embodiment, the second transfer mechanism includes a transfer conveyor belt 11, a turntable mechanism 12, and a can unloading conveyor belt 13. The transfer conveyor belt 11 is installed on a transfer station and is used to transport the filled beer cans located at the transfer station to the capping station. The turntable mechanism 12 is installed on a frame 1, and the capping station, sealing station, cleaning station, and unloading station are arranged around the turntable mechanism 12. The turntable mechanism 12 is used to sequentially transport the beer cans located at the capping station to the sealing station, cleaning station, and unloading station. The can unloading conveyor belt 13 is installed on the unloading station and is used to transport the beer cans located at the unloading station out. The second transfer mechanism described above has a reasonable and compact structural design and can stably and quickly transport the filled beer cans located at the transfer station to the capping station, sealing station, and unloading station sequentially.

[0084] Furthermore, the upper tank conveyor belt 2, the intermediate conveyor belt 11, and the lower tank conveyor belt 13 are all stainless steel chain conveyor belts, and their bearings are equipped with oil seal structures. The carbon dioxide blowing mechanism 3, the left and right push plate mechanism 9, the front and rear push plate mechanism 10, the filling mechanism 4, the can lid dispensing mechanism 5, and the sealing machine 6 are all located above the upper tank conveyor belt 2, the intermediate conveyor belt 11, and the lower tank conveyor belt 13, which facilitates workers to directly wash and clean the upper tank conveyor belt 2, the intermediate conveyor belt 11, and the lower tank conveyor belt 13.

[0085] Please see Figure 3 Specifically, the turntable mechanism 12 includes an arc-shaped platform 1201, a turntable 1202 disposed above the arc-shaped platform 1201, and a rotating module 1203 for driving the turntable 1202 to rotate. The center of the turntable 1202 and the center of the arc-shaped platform 1201 are located on the same vertical line, and the diameter of the turntable 1202 is smaller than the diameter of the arc-shaped platform 1201. One end of the arc-shaped platform 1201 is connected to the transfer conveyor belt 11, and the other end of the arc-shaped platform 1201 is connected to the lower... The can conveyor belt 13 is connected to the can. An arc-shaped guide bar 1204 is provided on the outer side of the arc-shaped platform 1201. Multiple evenly distributed third arc-shaped limiting grooves 12021, matching the side contours of the beer cans, are provided on the outer side of the turntable 1202. These third arc-shaped limiting grooves 12021 cooperate with the arc-shaped guide bar 1204 to move the beer cans along the arc-shaped platform 1201, thereby sequentially conveying the beer cans located at the capping station to the sealing station, cleaning station, and unloading station. The rotating module 1203 rotates the turntable 1202 at a constant angle each time. Each time the rotating module 1203 rotates the turntable 1202, a third arc-shaped limiting groove 12021 corresponds to each of the capping, sealing, and unloading stations on the turntable 1202. The aforementioned turntable mechanism 12 has a simple and compact structure, and can stably and quickly transport the filled beer cans located at the transfer station to the capping station, sealing station, cleaning station, and unloading station in sequence.

[0086] Please see Figure 1 In one embodiment, a temporary storage platform 14 is provided on the outer side of the lower can conveyor belt 13. Since the lower can conveyor belt 13 can only hold a limited number of finished bottled beer, the temporary storage platform 14 facilitates workers to temporarily store the finished bottled beer for better unloading operations.

[0087] Please see Figure 4In one embodiment, the upper conveyor belt 2 is equipped with multiple parallel conveyor chains 201 for transporting beer cans. Each conveyor chain 201 has limit guide strips 202 on both sides to facilitate workers in accurately placing beer cans onto each conveyor chain 201 for loading, effectively improving the loading speed. Each conveyor chain 201 has a position sensor 203 at its end to sense whether the beer can has reached the blowing station. The carbon dioxide blowing mechanism 3 includes multiple blowing components 301 and a lifting module 302 for driving the blowing components 301 up and down. Each blowing component 301 corresponds to one conveyor chain 201. When any position sensor 203 senses that a beer can has arrived at the blowing station, the lifting module 302 is activated, driving the blowing pipe of the blowing component 301 down into the beer can to blow carbon dioxide gas into the beer can, thus blowing out the oxygen inside the can.

[0088] Please see Figures 5 to 7 In one embodiment, the filling mechanism 4 includes a plurality of parallel and independent isobaric filling components 401. The number of isobaric filling components 401 is the same as the number of conveyor chains 201 of the upper can conveyor belt 2, and the isobaric filling components 401 correspond one-to-one with the conveyor chains 201 of the upper can conveyor belt 2. At the same time, when one or more positioning sensors 203 do not detect a beer can, but other positioning sensors 203 detect a beer can, the isobaric filling component 401 corresponding to the beer can that was not detected will not perform the filling operation. Only the isobaric filling component 401 corresponding to the beer can that was detected will perform the filling operation.

[0089] Each isobaric filling assembly 401 is connected to a waste liquid venting assembly 402 for gas-liquid separation and gas filtration. The isobaric filling assembly 401 includes a filling head 4011, a lifting assembly fixed to the filling head 4011, and a moving assembly located below the filling head 4011. The lifting end of the lifting assembly is connected to the moving assembly and drives the moving assembly to rise and fall. The waste liquid venting assembly 402 includes a primary waste liquid tank 4021 for gas-liquid separation and a secondary waste liquid tank 4022 for gas filtration. The air and liquid inlet of the primary waste liquid tank 4021 is connected to the exhaust and discharge outlet of the filling head 4011, and the exhaust outlet of the primary waste liquid tank 4021 is connected to the exhaust outlet of the secondary waste liquid tank 4022. The air inlet is connected, and the exhaust port of the secondary waste liquid tank 4022 is connected to the exhaust valve. The secondary waste liquid tank 4022 stores clean water. The gas (carbon dioxide) discharged from the primary waste liquid tank 4021 passes through the clean water and is discharged from the exhaust port of the secondary waste liquid tank 4022. The clean water in the secondary waste liquid tank 4022 can filter the incoming gas, dissolving impurities (such as alcohol mist) in the water. This prevents the discharged carbon dioxide gas from carrying alcohol mist through the exhaust valve and the exhaust port at the end of the exhaust pipe, allowing the equipment to continue to exhaust and dispense alcohol normally even after long-term use. Since the overflowing alcohol may enter the exhaust and liquid outlet of the filling head 4011 after filling, to prevent alcohol from entering the secondary waste liquid tank 4022 and affecting the filtration effect of the clean water, a primary waste liquid tank 4021 needs to be set up before the secondary waste liquid tank 4022 for gas-liquid separation.

[0090] Please see Figure 5 , Figure 6 In one embodiment, the lifting assembly includes a servo drive assembly, a guide assembly, and a guide shaft 4012. The top of the guide shaft 4012 is fixed to both ends of the guide assembly, and its bottom is fixed to both ends of the moving assembly. The servo drive assembly and the filling head 4011 are fixed to the upper and lower sides of a fixed plate 4013, respectively. The two ends of the fixed plate 4013 are respectively fitted onto the guide shaft 4012. If the accuracy of the lifting assembly is not high enough, after repeated use, the moving assembly may become 1-2 mm higher than the transfer platform 8, as is the case with traditional cylinder / electric cylinder driven lifting assemblies. If the moving assembly is 1-2 mm higher than the transfer platform 8, the front and rear push plate mechanism 10 cannot smoothly push the inflated beer can from the transfer platform 8 onto the moving assembly that has descended to the filling station. To avoid this situation, the present invention uses a lifting assembly composed of the aforementioned servo drive assembly, guide assembly, and guide shaft 4012, which can still accurately drive the moving assembly to rise and fall after long-term use.

[0091] Please see Figure 5 , Figure 6Specifically, the servo drive assembly includes a servo motor 4014, a lead screw 4015, a lead screw slider 4016, a motor push rod 4017, and a push rod guide seat 4018. The servo motor 4014 is preferably a motor with a brake. The drive shaft of the servo motor 4014 is connected to the lead screw 4015. The lead screw slider 4016 is threaded onto the lead screw 4015. The bottom of the motor push rod 4017 is fitted onto the lead screw slider 4016 and fixed thereto. Guide sliders 40171 are provided on opposite sides of the motor push rod 4017. The push rod guide seat 4018 is fitted over the lead screw slider 4016 and the motor push rod 4017 and fixed to the servo motor 4014. The top of the motor push rod 4017 passes through the push rod guide seat 4018 and connects to the guide assembly. Guide grooves 40181 for the guide slider 40171 to slide up and down are provided on opposite sides of the push rod guide seat 4018. After the servo motor 4014 starts, its drive shaft drives the lead screw 4015 to rotate. Since the motor push rod 4017 is fixed to the lead screw slider 4016, and the guide sliders 40171 on both sides of the push rod guide seat 4018 are located within the guide grooves 40181 of the push rod guide seat 4018, when the lead screw 4015 rotates, the motor push rod 4017 moves up and down relative to the push rod guide seat 4018, thereby driving the moving component to move up and down through the guide assembly. Using the servo motor 4014 for driving has a long service life, exceeding 10 years, and requires no frequent maintenance. In contrast, using a pneumatic / electric cylinder drive has a service life of only 2-3 years and requires frequent maintenance.

[0092] Please see Figure 5 Furthermore, the guide assembly includes a guide shaft fixing plate 4019 and a movable top plate 40110. Both ends of the guide shaft fixing plate 4019 are fixed to the top of the guide shaft 4012. The movable top plate 40110 is fixed to the guide shaft fixing plate 4019 around its perimeter via connectors 40111. A compression spring 40112 is fitted onto the connectors 40111 located below the guide shaft fixing plate 4019. The compression spring 40112 acts as a buffer during the upward movement of the moving assembly. It is worth noting that the connectors 40111 are not limited to fasteners such as screws or bolts. Preferably, the outer side of the push rod guide seat 4018 is provided with an clearance opening 40182 corresponding to the position of each compression spring 40112, to make the structure of the isobaric filling assembly 401 more compact.

[0093] Please see Figure 5Furthermore, a sensing plate 40113 is provided on one side of the guide shaft fixing plate 4019, and a reference point sensor 40114 that cooperates with the sensing plate 40113 is provided on the side of the servo motor 4014 near the sensing plate 40113. The reference point sensor 40114 is fixed to the servo motor 4014 by a sensor bracket. By setting the sensing plate 40113 and the reference point sensor 40114, the servo motor 4014 can accurately return to the initial position after each up-and-down movement of the moving component, thereby ensuring the accuracy of the lifting component.

[0094] Please see Figure 5 In one embodiment, the moving component includes a tray 40115 for holding beer cans. The left and right ends of the tray 40115 are respectively fixed to the bottom of the guide shaft 4012, so that the tray 40115 can hold beer cans without affecting the front and rear push plate mechanism 10 to push beer cans onto the tray 40115 and push beer cans on the tray 40115 to the transfer station.

[0095] Please see Figure 5 In one embodiment, the isobaric filling assembly 401 further includes a cantilever beam load cell 40116 and a weighing bracket 40117. The cantilever beam load cell 40116 is model DYX-306. The lifting assembly and the force-bearing end of the cantilever beam load cell 40116 are fixed on the fixed plate 4013, and the fixed end of the cantilever beam load cell 40116 is fixed on the weighing bracket 40117. The weighing bracket 40117 is fixed to the frame 1. By suspending the isobaric filling assembly 401 entirely on the cantilever beam load cell 40116, the beer can is placed on the moving assembly during use, and the opening of the beer can is connected to the filling head 4011 by the lifting assembly, thereby achieving the purpose of synchronous weighing during beer can filling. In addition, because the cantilever beam load cell 40116 has high detection accuracy and is not affected by the external environment, it can accurately control the liquid flow rate and velocity, avoiding the problem of wasting a lot of liquid during the machine debugging stage.

[0096] In one embodiment, the filling head 4011 includes a filling body and a filling sealing plate disposed around the filling body. The bottom of the filling sealing plate is provided with a food-grade silicone sealing gasket surrounding the filling head 4011. The upper end of the filling body is provided with a first interface for connecting an exhaust and liquid drain pipe and a second interface for connecting a beer storage tank and a gas source. The lower end of the filling body is provided with an exhaust and liquid drain outlet and a liquid outlet. The exhaust and liquid drain outlet communicates with the first interface, and the liquid outlet communicates with the second interface. When the mouth of the beer tank is pushed against the food-grade silicone sealing gasket by the lifting assembly, the exhaust and liquid drain outlet and the liquid outlet are enclosed within the mouth of the tank to prevent air leakage at the bottle mouth during the filling process, thus preventing the generation of excessive foam.

[0097] Please see Figure 8In one embodiment, the can cap dispensing mechanism 5 includes a fixed support 501, a material rack 502, a dispensing mechanism 503, and a capping mechanism 504. The material rack 502 is mounted on the fixed support 501 and is used to stack can caps, enabling the storage of multiple can caps at once. The dispensing mechanism 503 is mounted on the fixed support 501 and located on the bottom side of the material rack 502. The dispensing mechanism 503 is used to distribute the bottommost can cap in the material rack 502 to the mouth of the beer can located at the capping station. The capping mechanism 504 is mounted on the fixed support 501 and located directly above the capping station. The capping mechanism 504 is used to press the can cap tightly onto the mouth of the beer can. The can cap dispensing mechanism 5 described above enables the can cap dispensing and pressing operations to be completed at one station, eliminating the need for additional capping equipment, reducing space requirements, lowering costs, and effectively improving production speed.

[0098] Please see Figure 5 In one embodiment, the material rack 502 includes a can lid guide sleeve 5021 and multiple can lid support rods 5022 uniformly arranged circumferentially on the top of the can lid guide sleeve 5021. The can lid guide sleeve 5021 is fixed to the fixed bracket 501. The top of the multiple can lid support rods 5022 forms a feeding port, and the bottom opening of the can lid guide sleeve 5021 is a discharging port. The shapes of the feeding port and the discharging port are matched with the shape of the can lid, so that the can lids can be neatly stacked in the multiple can lid support rods 5022 and the can lid guide sleeve 5021 in the same direction.

[0099] Please see Figures 9 to 12In one embodiment, the material distribution mechanism 503 includes a can lid separator 5031 and a transverse drive assembly for driving the can lid separator 5031 to move back and forth towards the can lid dropping station. The can lid separator 5031 is provided with two opposing separation plates 5032 at one end near the capping mechanism 504. The distance between the two separation plates 5032 is smaller than the diameter of the can lid. The upper part of the can lid separator 5031 away from the capping mechanism 504 is provided with two opposing can lid dropping steps 5033. The distance between the two can lid dropping steps 5033 is smaller than the diameter of the can lid. The distance between the can lid dropping steps 5033 and the separation plates 5032 is equal to the edge thickness of the can lid. The lower part of the can lid separator 5031 away from the capping mechanism 504 is provided with a pusher plate 5034. Initially, the bottom can lid in the material rack 502 is supported by two separating plates 5032. When the material distribution mechanism 503 distributes the material, the lateral drive assembly drives the can lid separator 5031 to move towards the can lid dropping station. The two can lid dropping steps 5033 move directly below the material rack 502 to support the bottom can lid. At this time, the can lids stacked in the material rack 502 move downwards by a distance equal to the edge thickness of one can lid. When the lateral drive assembly drives the can lid separator 5031 to move back, the two separating plates 5032 insert into the bottom can lid and... Between the edges of the can lids above, the second to last can lid is supported, and the bottom can lid falls on the fixed base plate 5011 of the fixed bracket 501 and is located on the movement path of the pusher plate 5034; when the lateral drive assembly drives the can lid separator 5031 to move towards the can lid dropping station again, the pusher plate 5034 pushes the can lid on the fixed base plate 5011 onto the mouth of the beer can located at the can lid dropping station. At this time, the second to last can lid falls on the two can lid dropping steps 5033, and this cycle continues until all the can lids in the material rack 502 are distributed.

[0100] Please see Figure 12 Furthermore, the bottom of the fixed bracket 501 is provided with a Z-shaped fixed base plate 5011. The lower part of the fixed base plate 5011, corresponding to the position of the pusher plate 5034, is provided with a clearance groove 50111 for the pusher plate 5034 to move back and forth towards the cap-dropping station. The width of the clearance groove 50111 is smaller than the diameter of the can cap. A cap-dropping opening 50112 is provided in the middle of the fixed base plate 5011, and the cap-dropping opening 50112 communicates with the clearance groove 50111. The clearance groove 50111 is designed to be smaller than the diameter of the can cap so that when the can cap falls from the cap-dropping step 5033, it lands on the fixed base plate 5011 and is positioned above the clearance groove 50111. This allows the pusher plate 5034 to smoothly push the can cap that has landed on the fixed base plate 5011 out of the cap-dropping opening 50112 and onto the mouth of the beer can located at the cap-dropping station.

[0101] Please see Figure 8Furthermore, the separating plate 5032 is provided with material distribution guide slopes 50321 on both the upper and lower sides of the end away from the capping mechanism 504, so that when the transverse drive assembly drives the can cap separator 5031 to move back, it can easily insert between the bottom can cap and the edge of the can cap above it, supporting the second to last can cap.

[0102] Please see Figure 8 Furthermore, the lateral drive assembly includes a material distribution drive motor 5035, a first rotating shaft plate 5036, a second rotating shaft plate 5037, a linear slide rail 5038, and a linear slider 5039. The material distribution drive motor 5035 is vertically fixed to the fixed bracket 501. The output shaft of the material distribution drive motor 5035 is connected to one end of the first rotating shaft plate 5036. The other end of the first rotating shaft plate 5036 is rotatably connected to one end of the second rotating shaft plate 5037. The other end of the second rotating shaft plate 5037 is rotatably connected to the end of the can lid separator 5031 away from the capping mechanism 504. The upper side of the linear slide rail 5038 is fixed to the fixed bracket 501. The lower side of the linear slide rail 5038 is slidably connected to the upper side of the linear slider 5039. The lower side of the linear slider 5039 is fixed to the can lid separator 5031. Preferably, two linear guide rails 5038 and two linear sliders 5039 are provided. One linear guide rail 5038 and one corresponding linear slider 5039 constitute a set of right-angle guide components. The two sets of right-angle guide components are respectively set on the top two sides of the can lid separator 5031, so that the material distribution drive motor 5035 can stably drive the can lid separator 5031 to move back and forth towards the lid dropping station. The above-mentioned transverse drive component has an ingenious structure, high precision, and small horizontal area, making the overall structure of the material distribution mechanism 503 more compact.

[0103] Please see Figure 13 In one embodiment, the capping mechanism 504 includes an electromagnet bracket 5041, an electromagnet body 5042, and an electromagnet core 5043. The electromagnet body 5042 is fixed to a fixed bracket 501 via the electromagnet bracket 5041. The electromagnet body 5042 is connected to the electromagnet core 5043 and drives the electromagnet core 5043 to press against the can lid located at the cap-dropping station. When the can lid falls onto the mouth of the beer can, the electromagnet body 5042 is activated, controlling the electromagnet core 5043 to press against the can lid located at the cap-dropping station, thus pressing the can lid tightly against the mouth of the beer can. The capping mechanism 504 described above has a simple structure, stable operation, low cost, and long service life.

[0104] Please see Figure 8 In one embodiment, a material shortage sensor 505 is provided on one side of the lower end of the material rack 502. The sensing end of the material shortage sensor 505 faces the can lid inside the material rack 502. The material shortage sensor 505 can identify whether the can lid inside the material rack 502 is almost used up, thereby reminding the worker to replenish the material in time.

[0105] Please see Figure 1 In one embodiment, the miniaturized, high-precision, isobaric automatic beer filling equipment also includes a control display screen 15. The display screen is mounted on the frame 1 and is electrically connected to the upper can conveyor belt 2, the carbon dioxide blowing mechanism 3, the first transfer mechanism, the filling mechanism 4, the second transfer mechanism, the can cap dispensing mechanism 5, the sealing machine 6, and the cleaning mechanism 7. The control display screen 15 is used to control the operation of each mechanism to realize a series of actions such as feeding, blowing, can transfer, filling, capping, sealing, cleaning, and unloading.

[0106] In one embodiment, the miniaturized, high-precision isobaric automatic beer filling equipment also includes a host computer control system. This system, developed using Android, can collect all sensor data from the equipment, monitor equipment status, record filling data, and upload it to a backend database in real time. This enables remote monitoring of the equipment and automatic data processing and analysis of the brewery's filling data.
