Description

Technical Field

[0001] The utility model relates to the technical field of filling, and particularly relates to a filling device. Background Art

[0002] From brewing to sales, there are many filling processes for beer. The beer brewing process is always in a closed space, and carbon dioxide is continuously generated during the fermentation process. This process will increase the pressure in the closed space, thereby dissolving more carbon dioxide into the liquor. During the filling process, due to pressure changes, friction between the liquor and the pipeline, and temperature changes between two containers, the carbon dioxide in the liquor will be released, resulting in a large amount of foam. Pressure change is the biggest reason for foam generation. Therefore, isobaric filling technology is mostly used in the industry to solve the foam problem.

[0003] The Chinese utility model patent document with the publication number of CN117658040A discloses an isobaric filling machine, which includes several filling mechanisms arranged in a cabinet for filling beer. The filling mechanism includes a filling head, a lifting component fixed on the filling head, a moving component arranged below the filling head, and a double waste liquid exhaust component. The cup is placed on or sleeved on the moving component, and the lifting end of the lifting component is connected to the moving component and drives the moving component to lift. This filling mechanism can perform isobaric filling on beer containers to reduce the foam generated during the beer filling process.

[0004] However, in the above isobaric filling machine, since the diameter of the liquid outlet part of its filling head is fixed, the isobaric filling machine is only applicable to containers with an opening diameter larger than the liquid outlet part of the filling head, and cannot be compatible with small-diameter containers, resulting in poor versatility.

It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0048] Please refer to Figures 1 to 14 , this embodiment provides a filling device, including a cabinet 1, and a filling mechanism 2 and a double waste liquid exhaust mechanism 3 arranged in the cabinet 1.

[0049] The filling mechanism 2 is specifically installed on a filling fixing plate 101 inside the cabinet 1. Among them, the filling mechanism 2 includes a filling head 201, a lifting assembly 202, a moving assembly 203, a weighing substrate 204, a cantilever beam weighing sensor 205, a weighing bracket 206 and a soft rubber seal 207. The moving assembly 203 is arranged below the filling head 201. The lifting end of the lifting assembly 202 passes through the opening of the filling fixing plate 101 and is connected to the moving assembly 203. The filling head 201, the lifting assembly 202 and the force receiving end of the cantilever beam weighing sensor 205 are all fixed on the weighing substrate 204. The fixed end of the cantilever beam weighing sensor 205 is fixed on the filling fixing plate 101 through the weighing bracket 206. There is a gap between the filling fixing plate 101 and the weighing substrate 204. The soft rubber seal 207 is arranged at the bottom of the weighing substrate 204 and seals the gap.

[0050] By suspending the entire filling mechanism 2 on the cantilever beam load cell 205, during use, connect the filling head 201 to the double waste liquid exhaust mechanism 3, as well as external wine tanks, carbon dioxide tanks, and water buckets. Place or hang the container on the moving component 203, and connect the opening of the container to the filling head 201 through the lifting component 202, thereby achieving the purpose of synchronous weighing during container filling. Due to the high detection accuracy of the cantilever beam load cell 205 and its immunity to the external environment, precise control of the liquid discharge flow rate and velocity is achieved, avoiding the problem of wasting a large amount of beverages during the machine debugging stage. Additionally, by setting the soft rubber seal 207 to block the gap between the filling fixing plate 101 and the weighing substrate 204, not only does it not affect the normal filling and weighing processes, but it also significantly improves the sealing performance of the cabinet 1, preventing the influence of external dust, moisture, and other adverse factors on the filling equipment and the filling process, making the cleaning of the filling head 201 more convenient and thorough, and ensuring the cleanliness of the filling environment and the hygienic quality of the product.

[0051] Please refer to Figures 4 to 11 , the filling head 201 includes a filling main body 2011, a cup plug 2012, a bottle plug 2013, a first filling gasket 2014, and a second filling gasket 2015. The first filling gasket 2014 is provided on the periphery of the filling main body 2011, and the second filling gasket 2015 is provided on the periphery of the bottle plug 2013. The upper end of the filling main body 2011 is provided with an exhaust and liquid discharge joint 2016 for connecting to the double waste liquid exhaust mechanism 3 and an air and liquid inlet joint 2017 for connecting to the wine tank and the carbon dioxide tank. The middle of the bottom of the filling main body 2011 is provided with an installation cavity 20111, and a plurality of circumferentially distributed first liquid discharge ports 20112 are provided on the outer wall of the bottom of the filling main body 2011. The installation cavity 20111 is respectively communicated with the exhaust and liquid discharge joint 2016, the air and liquid inlet joint 2017, and the first liquid discharge ports 20112.

[0052] The cup plug 2012 is provided with a first exhaust and liquid discharge port 201221 that penetrates up and down. When the cup plug 2012 is installed in the installation cavity 20111, the first exhaust and liquid discharge port 201221 is communicated with the exhaust and liquid discharge joint 2016. The outer wall of the cup plug 2012 and the inner wall of the installation cavity 20111 form a first liquid and air inlet cavity 2018 that communicates the plurality of first liquid discharge ports 20112 with the air and liquid inlet joint 2017. When the opening of the container is pushed against the first filling gasket 2014 by the lifting component 202, the first exhaust and liquid discharge port 201221 and the first liquid discharge ports 20112 can be surrounded within the opening, preventing air leakage at the opening during the filling process and generating a large amount of foam.

[0053] The stopper 2013 is provided with a second exhaust and drainage port 201331 that penetrates up and down. A plurality of circumferentially distributed second liquid outlets 20134 are provided on the bottom outer wall of the stopper 2013. When the stopper 2013 is installed in the installation cavity 20111, the outer wall of the stopper 2013 blocks a plurality of first liquid outlets 20112. The second exhaust and drainage port 201331 is communicated with the exhaust and drainage joint 2016, and a plurality of second liquid outlets 20134 are communicated with the air inlet and liquid inlet joint 2017. Moreover, the second filling gasket 2015 is located at the bottom of the filling main body 2011. When the opening of the container is pushed against the second filling gasket 2015 driven by the lifting assembly 202, the second exhaust and drainage port 201331 and the second liquid outlets 20134 can be surrounded within the opening to prevent air leakage at the opening during the filling process, thus generating a large amount of foam.

[0054] By providing the replaceable cup stopper 2012 and the stopper 2013, the filling head 201 can adapt to containers with different caliber sizes. Whether it is a cup-shaped container with a large caliber or a bottle-shaped container with a small caliber, filling can be achieved by replacing the corresponding components, greatly improving the versatility and flexibility of the filling mechanism 2. For example, when the opening caliber of the container (such as a cup-shaped container) is large, the cup stopper 2012 is selected to be installed on the installation cavity 20111 of the filling main body 2011, and filling is carried out using the first liquid outlet 20112 on the filling main body 2011 and the first exhaust and drainage port 201221 on the cup stopper 2012; when the opening caliber of the container (such as a bottle-shaped container) is small, the stopper 2013 is selected to be installed on the installation cavity 20111 of the filling main body 2011, and filling is carried out using the second liquid outlet 20134 and the second exhaust and drainage port 201331 of the stopper 2013. The diameter of the stopper 2013 is smaller than the diameter of the filling main body 2011.

[0055] It should be noted that although the cup-shaped container can be filled using the stopper 2013 with a smaller diameter, since the distance between the second liquid outlet 20134 of the stopper 2013 and the inner wall of the cup-shaped container is large, the liquid ejected from the second liquid outlet 20134 will slide down a certain distance before contacting the inner wall of the cup-shaped container. This will cause the liquid ejected to directly hit the liquid surface in the container before the cup-shaped container is filled with liquid, thereby generating foam. Therefore, it is necessary to replace the cup stopper 2012 and use the first liquid outlet 20112 on the filling main body 2011 and the first exhaust and drainage port 201221 on the cup stopper 2012 to fill the cup-shaped container to avoid foam generation.

[0056] Please refer to Figures 6 to 8, in one embodiment, an exhaust and liquid discharge channel 20113 that penetrates up and down is provided at the top of the installation cavity 20111. The cup plug 2012 includes a cup plug body 20121 and a cup plug screw 20122. The cup plug body 20121 is provided with a first screw through hole 201211 that penetrates up and down. The cup plug screw 20122 is provided with a first exhaust and liquid discharge port 201221 that penetrates up and down. The cup plug screw 20122 penetrates into the first screw through hole 201211 from bottom to top, and the upper end of the cup plug screw 20122 extends upward out of the first screw through hole 201211. When installing the cup plug 2012, first insert the cup plug body 20121 into the installation cavity 20111, and then insert the cup plug screw 20122 along the first screw through hole 201211 of the cup plug body 20121, so that the upper end of the cup plug screw 20122 is threadedly connected to the lower end of the exhaust and liquid discharge channel 20113. After tightening, the installation of the cup plug 2012 is completed. After the cup plug 2012 is installed in the installation cavity 20111, the exhaust and liquid discharge joint 2016 is communicated with the first exhaust and liquid discharge port 201221 through the exhaust and liquid discharge channel 20113. The outer wall of the cup plug body 20121 and the inner wall of the installation cavity 20111 form a first liquid and gas inlet cavity 2018. The liquid and gas inlet joint 2017 is communicated with a plurality of first liquid discharge ports 20112 through the first liquid and gas inlet cavity 2018. The above cup plug 2012 is fixed by the combined structure of the cup plug body 20121 and the cup plug screw 20122 and uses threaded connection, making the installation and disassembly of the cup plug 2012 simple and fast, facilitating the daily maintenance and replacement of the equipment, and reducing the maintenance cost and time.

[0057] Please refer to Figures 6 to 8 , in one embodiment, a first seal 20123 is sleeved on the outer wall of the lower end of the cup plug body 20121, and a second seal 20124 surrounding the first screw through hole 201211 is provided at the top of the cup plug body 20121. After the cup plug 2012 is installed in the installation cavity 20111, the first seal 20123 can effectively fill the gap between the cup plug body 20121 and the inner wall of the installation cavity 20111, preventing liquid or gas from leaking from this gap. The second seal 20124 can further prevent liquid or gas from leaking from the screw through hole, thus ensuring the sealing performance during the filling process.

[0058] Please refer to Figures 9 to 11, in one embodiment, the bottle stopper 2013 includes a first bottle stopper member 20131, a second bottle stopper member 20132, and a bottle stopper screw 20133. The second filling gasket 2015 is sleeved outside the second bottle stopper member 20132. The second bottle stopper member 20132 is sleeved outside the first bottle stopper member 20131. A plurality of second liquid outlets 20134 are formed between the bottom of the second bottle stopper member 20132 and the outer wall of the lower end of the first bottle stopper member 20131. A second liquid inlet and air inlet cavity 20135 communicating with the plurality of second liquid outlets 20134 is formed between the inner wall of the second bottle stopper member 20132 and the outer wall of the upper end of the first bottle stopper member 20131. The first bottle stopper member 20131 is provided with a second screw through hole 201311 penetrating up and down. The bottle stopper screw 20133 is provided with a second exhaust and liquid discharge port 201331 penetrating up and down. The bottle stopper screw 20133 penetrates into the second screw through hole 201311 from bottom to top, and the upper end of the bottle stopper screw 20133 extends upward out of the second screw through hole 201311. When installing the bottle stopper 2013, first insert the second bottle stopper member 20132 into the installation cavity 20111, then sleeve the first bottle stopper member 20131 inside the second bottle stopper member 20132, and then insert the bottle stopper screw 20133 along the second screw through hole 201311 of the first bottle stopper member 20131, so that the upper end of the bottle stopper screw 20133 is threadedly connected to the lower end of the exhaust and liquid discharge channel 20113. After tightening, the installation of the bottle stopper 2013 is completed. After the bottle stopper 2013 is installed, the outer wall of the second bottle stopper member 20132 blocks a plurality of first liquid outlets 20112. The exhaust and liquid discharge joint 2016 is communicated with the second exhaust and liquid discharge port 201331 through the exhaust and liquid discharge channel 20113. The plurality of second liquid outlets 20134 are communicated with the exhaust and liquid discharge joint 2016 through the second liquid inlet and air inlet cavity 20135. The above bottle stopper 2013 is fixed by the combined structure of the first bottle stopper member 20131, the second bottle stopper member 20132, and the bottle stopper screw 20133, and is fixed by using threaded connection, making the installation and disassembly of the bottle stopper 2013 simple and fast, facilitating the daily maintenance and replacement of the equipment, and reducing the maintenance cost and time. The setting of the second bottle stopper member 20132 not only blocks the first liquid outlets 20112 to prevent liquid or gas from flowing out of the first liquid outlets 20112, but also provides an installation position for the second filling gasket 2015, and at the same time can cooperate with the first bottle stopper member 20131 to form the second liquid outlets 20134 and the second liquid inlet and air inlet cavity 20135 to realize the filling of the bottled container.

[0059] Please refer to Figures 9 to 11, in one embodiment, an annular sealing protrusion 201321 for blocking a plurality of first liquid outlets 20112 is provided on the outer wall of the second stopper member 20132.

[0060] Please refer to Figures 12 to 14 , in one embodiment, the soft rubber seal 207 includes a fixed outer ring 2071, a fixed inner ring 2072, and a deformation groove 2073 provided between the fixed outer ring 2071 and the fixed inner ring 2072. The fixed outer ring 2071 is fixed to the filling fixing plate 101, and the fixed inner ring 2072 is fixed to the weighing substrate 204. The fixed connection between the fixed outer ring 2071 and the filling fixing plate 101, and the fixed connection between the fixed inner ring 2072 and the weighing substrate 204 together form a sealed boundary. This boundary, through the elastic characteristics of the soft rubber seal 207, closely adheres between the two fixed surfaces, thus effectively preventing liquid, dust, or other contaminants from penetrating through the gap.

[0061] Specifically, a support frame 208 is provided at the bottom of the weighing support 206. The support frame 208 is fixed to the filling fixing plate 101. An outer ring fixing member 209 surrounding the weighing substrate 204 is provided at the bottom of the support frame 208. The fixed outer ring 2071 is fixed to the bottom of the outer ring fixing member 209, and the bottom surface of the fixed outer ring 2071 presses on the top surface of the filling fixing plate 101 to block the gap between the filling fixing plate 101 and the weighing substrate 204. Through the above settings of the support frame 208 and the outer ring fixing member 209, the filling seat (the lifting assembly 202, the moving assembly 203, the weighing substrate 204, the cantilever beam weighing sensor 205, the weighing support 206, the soft rubber seal 207, etc.) can be disassembled from the filling fixing plate 101 as a whole. It only needs to remove the connection between the support frame 208 and the filling fixing plate 101, making the maintenance, cleaning, replacement, or upgrade of the equipment more convenient and fast, and reducing the maintenance cost and time cost.

[0062] Please refer to Figure 14, in one embodiment, a plurality of first fixing posts 20711 are circumferentially arranged at the top of the fixed outer ring 2071, and a plurality of first fixing holes 2091 that cooperate with the first fixing posts 20711 are circumferentially arranged at the bottom of the outer ring fixing member 209. Through the cooperation of the first fixing posts 20711 and the first fixing holes 2091, a quick and accurate connection between the fixed outer ring 2071 and the outer ring fixing member 209 is achieved, simplifying the installation process, improving the assembly efficiency, and at the same time ensuring the firmness of the connection.

[0063] Please refer to Figure 12 , Figure 13 , in one embodiment, the four corners of the support frame 208 are fixed to the filling fixing plate 101 through wing nuts 210. The wing nuts 210 are easy to manually tighten and loosen, and installation and adjustment can be carried out without special tools, greatly facilitating the maintenance and upgrade of the equipment.

[0064] Please refer to Figure 3 , Figure 4 , Figures 12 to 14 , in one embodiment, a filling sealing disc 211 is arranged around the filling head 201. The filling sealing disc 211 is fixed to the bottom of the weighing substrate 204. A first filling sealing gasket 2014 surrounding the filling head 201 is provided at the bottom of the filling sealing disc 211. The fixed inner ring 2072 is fixed to the bottom of the filling sealing disc 211 through an inner ring silicone pressing plate 212. The combination of the filling sealing disc 211 and the first filling sealing gasket 2014 ensures good sealing between the filling head 201 and the wine tank, preventing leakage and contamination during the filling process.

[0065] Specifically, a plurality of second fixing posts 2121 are circumferentially arranged at the top of the inner ring silicone pressing plate 212. A plurality of openings 20721 for the second fixing posts 2121 to pass through are circumferentially arranged on the fixed inner ring 2072. A plurality of second fixing holes 2111 that cooperate with the second fixing posts 2121 are circumferentially arranged at the bottom of the filling sealing disc 211. The inner ring silicone pressing plate 212 is firmly fixed to the bottom of the filling sealing disc 211 through the cooperation of the second fixing posts 2121 and the second fixing holes 2111, while pressing and fixing the fixed inner ring 2072, ensuring a tight connection between the soft rubber seal 207 and the weighing substrate 204, and the installation and disassembly are convenient, simplifying the installation process and improving the assembly efficiency.

[0066] In one embodiment, the cross-sectional shape of the deformation groove 2073 is a U-shaped structure. This setting of the deformation groove 2073 allows the soft rubber seal 207 to have a certain deformation space when under pressure, so as to better adapt to the micro-displacements and weighing during the filling process, maintaining the sealing effect while also increasing the durability and lifespan of the seal.

[0067] Please refer to Figure 3 ,Figure 4 , Figure 12 , Figure 13 , in one embodiment, the lifting assembly 202 includes a power source 2021, a guiding assembly 2022 and two guiding shafts 2023. The power source 2021 is fixed on the weighing substrate 204. The driving end of the power source 2021 is connected to the guiding assembly 2022 and drives the guiding assembly 2022 to lift. The tops of the two guiding shafts 2023 are respectively fixed at both ends of the guiding assembly 2022, and the bottoms are respectively fixed at both ends of the moving assembly 203. At the same time, both ends of the weighing substrate 204, the fixed inner ring 2072 of the soft rubber seal 207, the filling seal disc 211 and the inner ring silica gel pressing plate 212 are respectively sleeved on the two guiding shafts 2023, which can further strengthen the stability of the movement of the guiding shaft 2023. In this embodiment, the power source 2021 is driven by an electric cylinder, and a mechanism capable of providing power such as a cylinder can also be used. Driven by the electric cylinder, the guiding assembly 2022 moves upward, further driving the guiding shaft 2023 and the moving assembly 203 with the container placed thereon or sleeved thereon to move upward until the opening of the container reaches the filling seal disc 211, and the filling seal disc 211 seals the opening of the container.

[0068] Please refer to Figure 4 , Figure 5 , in one embodiment, the moving assembly 203 includes a tray 2031, and both ends of the tray 2031 are respectively fixed at the bottoms of the two guiding shafts 2023. The tray 2031 is used to hold the cup-shaped container and ensure that the cup-shaped container is aligned with the center of the filling head 201 during filling. Among them, the size of the tray 2031 is designed according to the specifications of the cup-shaped container. In addition, in order to be compatible with cup-shaped containers and bottle-shaped containers, hanging plate grooves 20231 are provided at the middle and lower ends of the two guiding shafts 2023; the moving assembly 203 further includes a bottle mouth hanging plate 2032 and two separating clamping sleeves 2033. A U-shaped opening 20321 is provided in the middle of the front surface of the bottle mouth hanging plate 2032, and the U-shaped opening 20321 is used to clamp the bottle mouth of the bottle-shaped container. U-shaped mounting grooves 20322 matching the hanging plate grooves 20231 are provided at both ends of the bottle mouth hanging plate 2032. When filling a cup-shaped container, the bottle mouth hanging plate 2032 does not need to be installed. When filling a bottle-shaped container, both ends of the bottle mouth hanging plate 2032 are hung on the hanging plate grooves 20231 of the two guiding shafts 2023 through the U-shaped mounting grooves 20322, and are respectively locked on the two guiding shafts 2023 by the two separating clamping sleeves 2033.

[0069] Please refer to Figure 12, in one embodiment, a sensor 213 for detecting whether a container is placed on the moving component 203 and identifying the type of the container is provided on the guiding component 2022, so that the power source 2021 can adjust the filling and sealing force according to the type of the container identified by the sensor 213, ensuring that each container can obtain a proper sealing effect, thus guaranteeing the filling quality and avoiding problems such as liquid leakage caused by insufficient sealing or container deformation caused by over-tight sealing. Due to the differences in the opening diameters and shapes of cup-shaped containers and bottle-shaped containers, different filling and sealing forces are required for sealing them. The sealing force for cup-shaped containers is greater than that for bottle-shaped containers. If the same filling and sealing force is used for both, it is likely to result in insufficient sealing effect for cup-shaped containers, leading to abnormal filling, or excessive filling and sealing force for bottle-shaped containers, causing deformation of the bottle-shaped containers. Since the speed at which the power source 2021 drives the moving component 203 to move is constant, and the time for the power source 2021 to drive different types of containers (when different types of containers are placed on or hung on the moving component 203, the distances from their openings to the filling head 201 are different) to the filling head 201 is different, it is possible to judge whether a cup-shaped container or a bottle-shaped container is placed on the moving component 203 according to the time when the sensor 213 receives the feedback signal, and to judge whether no cup-shaped container or bottle-shaped container is placed on the moving component 203.

[0070] Please refer to Figure 3 , in one embodiment, the double waste liquid exhaust assembly includes a primary waste liquid tank 301 for gas-liquid separation and a secondary waste liquid tank 302 for filtering gas. The air inlet and liquid inlet of the primary waste liquid tank 301 is communicated with the exhaust and drainage joint 2016 of the filling head 201. The exhaust port of the primary waste liquid tank 301 is communicated with the air inlet of the secondary waste liquid tank 302. The exhaust port of the secondary waste liquid tank 302 is communicated with an exhaust valve. Clear water is stored in the secondary waste liquid tank 302. The gas (carbon dioxide) discharged from the primary waste liquid tank 301 is discharged from the exhaust port of the secondary waste liquid tank 302 after passing through the clear water. The clear water in the secondary waste liquid tank 302 can play a role in filtering the incoming gas, dissolving impurities (such as wine mist) in the gas in the water, so as to avoid the discharged carbon dioxide gas carrying wine mist through the exhaust valve and the exhaust port at the end of the exhaust pipe, enabling the equipment to exhaust and dispense wine normally after long-term use. Since after the wine is filled, the overflowing wine liquid may enter the exhaust and drainage joint 2016 of the filling head 201, in order to prevent the wine liquid from entering the secondary waste liquid tank 302 and affecting the filtering effect of the clear water, it is necessary to set a primary waste liquid tank 301 in front of the secondary waste liquid tank 302 for gas-liquid separation.

[0071] Please refer to Figure 1 , Figure 2, in one embodiment, a transparent cabinet door 102 and an operation display screen 103 are provided on the front of the cabinet 1. The transparent cabinet door 102 corresponds to the filling mechanism 2, so that customers can see the filling process without opening the cabinet door. The operation display screen 103 is used for customers to place orders and make payments.
