Description

Technical Field

[0001] This invention relates to the field of filling technology, specifically to a filling device and a method for controlling the filling sealing force. Background Technology

[0002] From brewing to sales, beer undergoes numerous bottling processes. The brewing process takes place in a closed environment, where fermentation continuously produces carbon dioxide. This process increases the pressure within the closed space, causing more carbon dioxide to dissolve into the beer. During bottling, pressure changes, friction between the beer and pipes, and temperature variations between the two containers all release carbon dioxide from the beer, resulting in a large amount of foam. Pressure changes are the primary cause of foam generation; therefore, the industry largely uses isobaric bottling technology to address the foam problem.

[0003] Chinese invention patent document CN117658040A discloses an isobaric filling machine, comprising several filling mechanisms installed inside a cabinet for filling beer. Each filling mechanism includes a filling head, a lifting assembly fixed to the filling head, a moving assembly located below the filling head, and a dual waste liquid venting assembly. 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. This filling mechanism can perform isobaric filling of beer containers to reduce foam generated during the beer filling process.

[0004] However, in the aforementioned isobaric filling machine, because the diameter of the liquid outlet section of its filling head is fixed, the isobaric filling machine is only suitable for containers with an opening diameter larger than the liquid outlet section of the filling head, and cannot be compatible with small-diameter containers, resulting in poor versatility. Summary of the Invention

[0005] In order to overcome the problem of poor versatility in existing filling mechanisms due to the fixed diameter of the liquid outlet portion of the filling head, this invention provides a filling device and a method for controlling the filling sealing force.

The first bottle stopper is provided with a second screw hole that runs vertically through it. The bottle stopper screw is provided with a second vent and liquid outlet that runs vertically through it. The bottle stopper screw passes through the second screw hole from bottom to top, and the upper end of the bottle stopper screw extends upward out of the second screw hole. When the bottle stopper is installed in the mounting cavity, the outer wall of the second bottle stopper blocks several of the first liquid outlets. The upper end of the bottle stopper screw is threadedly connected to the lower end of the venting and draining channel. The venting and draining connector communicates with the second venting and draining port through the venting and draining channel. Several of the second liquid outlets communicate with the inlet and outlet connector through the second inlet and outlet chamber.

[0010] In a preferred embodiment of the present invention, the filling mechanism is installed on a filling fixing plate inside the cabinet. The filling mechanism further includes a lifting component, a moving component, a weighing base plate, a cantilever beam load cell, a weighing bracket, and a soft rubber seal.

[0020] Please see Figures 1 to 14 This embodiment provides a filling device, including a cabinet 1, a filling mechanism 2 and a dual waste liquid exhaust mechanism 3 disposed in the cabinet 1.

[0021] The filling mechanism 2 is specifically installed on the filling fixing plate 101 inside the cabinet 1. The filling mechanism 2 includes a filling head 201, a lifting component 202, a moving component 203, a weighing base plate 204, a cantilever beam load cell 205, a weighing bracket 206, and a soft rubber seal 207. The moving component 203 is located below the filling head 201. The lifting end of the lifting component 202 passes through the opening of the filling fixing plate 101 and is connected to the moving component 203. The force-bearing ends of the filling head 201, the lifting component 202, and the cantilever beam load cell 205 are all fixed on the weighing base plate 204. The fixed end of the cantilever beam load cell 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 base plate 204. The soft rubber seal 207 is located at the bottom of the weighing base plate 204 and seals the gap.

[0022] By suspending the filling mechanism 2 entirely on the cantilever beam load cell 205, during use, the filling head 201 is connected to the dual waste liquid exhaust mechanism 3 and external wine tanks, carbon dioxide tanks, and water tanks. Containers are placed or hung on the moving component 203, and the opening of the container is connected to the filling head 201 via the lifting component 202, thus achieving simultaneous weighing during container filling. Due to the high detection accuracy of the cantilever beam load cell 205 and its immunity to external environmental influences, precise control of the liquid flow rate and velocity is achieved, avoiding the waste of large quantities of beverage during machine debugging. Furthermore, by using a soft rubber seal 207 to seal the gap between the filling fixing plate 101 and the weighing base plate 204, not only is normal filling and weighing not affected, but the sealing performance of the cabinet 1 is significantly improved, preventing external dust, moisture, and other adverse factors from affecting the filling equipment and process. This makes cleaning the filling head 201 more convenient and efficient, ensuring the cleanliness of the filling environment and the hygienic quality of the product.

[0023] Please see Figures 4 to 11 The filling head 201 includes a filling body 2011, a cup stopper 2012, a bottle stopper 2013, a first filling sealing gasket 2014, and a second filling sealing gasket 2015. The first filling sealing gasket 2014 is located around the filling body 2011, and the second filling sealing gasket 2015 is located around the bottle stopper 2013. The upper end of the filling body 2011 is provided with an exhaust and liquid discharge connector 2016 for connecting the dual waste liquid exhaust mechanism 3 and an air and liquid inlet connector 2017 for connecting the wine tank and the carbon dioxide tank. The bottom center of the filling body 2011 is provided with an installation cavity 20111. The bottom outer wall of the filling body 2011 is provided with several circumferentially distributed first liquid outlets 20112. The installation cavity 20111 is connected to the exhaust and liquid discharge connector 2016, the air and liquid inlet connector 2017, and the first liquid outlets 20112, respectively.

[0024] The stopper 2012 is provided with a first vent and drain port 201221 that runs vertically through the container. When the stopper 2012 is installed in the mounting cavity 20111, the first vent and drain port 201221 is connected to the vent and drain connector 2016. The outer wall of the stopper 2012 and the inner wall of the mounting cavity 20111 form a first liquid and air inlet chamber 2018 that connects several first liquid outlets 20112 and air and liquid inlet connectors 2017. When the opening of the container is pushed against the first filling sealing gasket 2014 by the lifting assembly 202, the first vent and drain port 201221 and the first liquid outlet 20112 can be surrounded in the opening to prevent air leakage at the opening during the filling process and the generation of a large amount of foam.

[0025] The bottle stopper 2013 is provided with a second vent and drain port 201331 that runs vertically through the bottle. The bottom outer wall of the bottle stopper 2013 is provided with several circumferentially distributed second outlets 20134. When the bottle stopper 2013 is installed in the mounting cavity 20111, the outer wall of the bottle stopper 2013 blocks several first outlets 20112. The second vent and drain port 201331 is connected to the vent and drain connector 2016, and the several second outlets 20134 are connected to the air and liquid inlet connector 2017. The second filling sealing gasket 2015 is located at the bottom of the filling body 2011. When the container opening is pushed against the second filling sealing gasket 2015 by the lifting assembly 202, the second vent and drain port 201331 and the second outlets 20134 are enclosed within the opening to prevent air leakage during filling and the generation of excessive foam.

[0026] The filling head 201 is equipped with replaceable cup stopper 2012 and bottle stopper 2013, which allows the filling head 201 to be adapted to containers of different diameters. Whether it is a large-diameter cup-shaped container or a small-diameter bottle-shaped container, filling can be achieved by replacing the corresponding parts, which greatly improves the versatility and flexibility of the filling mechanism 2. For example, when the opening diameter of the container (such as a cup-shaped container) is large, the cup stopper 2012 is installed on the mounting cavity 20111 of the filling body 2011, and filling is performed using the first liquid outlet 20112 on the filling body 2011 and the first venting and draining port 201221 on the cup stopper 2012; when the opening diameter of the container (such as a bottle-shaped container) is small, the bottle stopper 2013 is installed on the mounting cavity 20111 of the filling body 2011, and filling is performed using the second liquid outlet 20134 and the second venting and draining port 201331 of the bottle stopper 2013, and the diameter of the bottle stopper 2013 is smaller than the diameter of the filling body 2011.

[0027] It should be noted that although a smaller diameter stopper 2013 can be used to fill cup-shaped containers, the greater distance between the second outlet 20134 of the stopper 2013 and the inner wall of the cup-shaped container causes the liquid sprayed from the second outlet 20134 to slide down a certain distance before contacting the inner wall. This results in the liquid spraying directly onto the surface of the liquid in the container before it is fully filled, thus creating foam. Therefore, the stopper 2012 needs to be replaced, and the first outlet 20112 on the filling body 2011 and the first vent and drain outlet 201221 on the stopper 2012 should be used to fill the cup-shaped containers to avoid foam generation.

[0028] Please see Figures 6 to 8In one embodiment, the top of the mounting cavity 20111 is provided with a vertically penetrating venting and draining channel 20113. The cup stopper 2012 includes a cup stopper body 20121 and a cup stopper screw 20122. The cup stopper body 20121 is provided with a vertically penetrating first screw hole 201211, and the cup stopper screw 20122 is provided with a vertically penetrating first venting and draining port 201221. The cup stopper screw 20122 is inserted into the first screw hole 201211 from bottom to top, and the upper end of the cup stopper screw 20122 extends upward out of the first screw hole 201211. When installing the cup stopper 2012, first insert the cup stopper body 20121 into the installation cavity 20111, then insert the cup stopper screw 20122 along the first screw through hole 201211 of the cup stopper body 20121, so that the upper end of the cup stopper screw 20122 is threadedly connected to the lower end of the vent and drain channel 20113. After tightening, the installation of the cup stopper 2012 is completed. After the cup stopper 2012 is installed in the installation cavity 20111, the vent and drain connector 2016 is connected to the first vent and drain port 201221 through the vent and drain channel 20113. The outer wall of the cup stopper body 20121 and the inner wall of the installation cavity 20111 form a first liquid and air inlet cavity 2018. The air and liquid inlet connector 2017 is connected to several first liquid outlets 20112 through the first liquid and air inlet cavity 2018. The aforementioned cup stopper 2012 uses a combination structure of cup stopper body 20121 and cup stopper screw 20122, and is fixed by threaded connection, which makes the installation and removal of cup stopper 2012 simple and quick, facilitates daily maintenance and replacement of equipment, and reduces maintenance costs and time.

[0029] Please see Figures 6 to 8 In one embodiment, a first sealing element 20123 is fitted onto the lower outer wall of the cup stopper body 20121, and a second sealing element 20124 is provided on the top of the cup stopper body 20121 to surround the first screw hole 201211. After the cup stopper 2012 is installed into the mounting cavity 20111, the first sealing element 20123 can effectively fill the gap between the cup stopper body 20121 and the inner wall of the mounting cavity 20111, preventing liquid or gas from leaking from the gap. The second sealing element 20124 can further prevent liquid or gas from leaking from the screw hole, thereby ensuring the sealing performance during the filling process.

[0030] Please see Figures 9 to 11In one embodiment, the bottle stopper 2013 includes a first bottle stopper 20131, a second bottle stopper 20132, and a bottle stopper screw 20133. A second filling sealing gasket 2015 is sleeved on the outside of the second bottle stopper 20132, and the second bottle stopper 20132 is sleeved on the outside of the first bottle stopper 20131. A plurality of second liquid outlets 20134 are formed between the bottom of the second bottle stopper 20132 and the lower outer wall of the first bottle stopper 20131. The inner wall of the second bottle stopper 20132 is connected to the first bottle stopper 20131. A second liquid inlet and air inlet chamber 20135 is formed between the upper outer walls of the bottle stopper 20131 and several second liquid outlets 20134. The first bottle stopper 20131 is provided with a second screw hole 201311 that runs vertically through it. The bottle stopper screw 20133 is provided with a second vent and liquid outlet 201331 that runs vertically through it. The bottle stopper screw 20133 is inserted into the second screw hole 201311 from bottom to top, and the upper end of the bottle stopper screw 20133 extends upward out of the second screw hole 201311. When installing bottle stopper 2013, first insert the second bottle stopper 20132 into the installation cavity 20111, then fit the first bottle stopper 20131 into the second bottle stopper 20132. Next, insert the bottle stopper screw 20133 along the second screw hole 201311 of the first bottle stopper 20131, so that the upper end of the bottle stopper screw 20133 is threadedly connected to the lower end of the venting and draining channel 20113. Tighten the screw to complete the installation of bottle stopper 2013. After installation, the outer wall of the second bottle stopper 20132 blocks several first liquid outlets 20112. The venting and draining connector 2016 connects to the second venting and draining port 201331 through the venting and draining channel 20113. Several second liquid outlets 20134 connect to the air and liquid inlet connector 2017 through the second liquid and air inlet chamber 20135. The aforementioned bottle stopper 2013 is constructed through a combination of a first bottle stopper 20131, a second bottle stopper 20132, and a bottle stopper screw 20133, and is fixed by a threaded connection. This makes the installation and removal of the bottle stopper 2013 simple and quick, facilitating daily maintenance and replacement of the equipment and reducing maintenance costs and time. The second bottle stopper 20132 not only seals the first liquid outlet 20112 to prevent liquid or gas from escaping from the first liquid outlet 20112, but also provides an installation position for the second filling sealing gasket 2015. At the same time, it can also work with the first bottle stopper 20131 to form a second liquid outlet 20134 and a second liquid inlet and air inlet chamber 20135 to achieve the filling of bottled containers.

[0031] Please see Figures 9 to 11In one embodiment, the outer wall of the second bottle stopper 20132 is provided with annular sealing protrusions 201321 for sealing a plurality of first liquid outlets 20112. The outer wall of the second bottle stopper 20132 is also fitted with a third sealing member 20136 and a fourth sealing member 20137. The third sealing member 20136 is located above the annular sealing protrusions 201321, and the fourth sealing member 20137 is located below the annular sealing protrusions 201321. The top of the first bottle stopper 20131 is provided with a fifth sealing member 20138 surrounding the second screw hole 201311. After the stopper 2012 is installed into the mounting cavity 20111, the third seal 20136 and the fourth seal 20137 can effectively fill the gap between the second stopper 20132 and the inner wall of the mounting cavity 20111, preventing liquid or gas from leaking out of the gap. The fifth seal 20138 can further prevent liquid or gas from leaking out of the screw hole, thereby ensuring the sealing during the filling process.

[0032] Please see 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 disposed 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 base plate 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 base plate 204, together form a sealed boundary. This boundary, through the elastic properties of the soft rubber seal 207, is tightly fitted between the two fixed surfaces, thereby effectively preventing liquids, dust, or other contaminants from penetrating into the gap.

[0033] Specifically, a support frame 208 is provided at the bottom of the weighing bracket 206. The support frame 208 is fixed to the filling fixing plate 101. An outer ring fixing member 209 surrounding the weighing base plate 204 is provided at the bottom of the support frame 208. A fixing outer ring 2071 is fixed to the bottom of the outer ring fixing member 209, and the bottom surface of the fixing outer ring 2071 presses against the top surface of the filling fixing plate 101 to seal the gap between the filling fixing plate 101 and the weighing base plate 204. With the above-mentioned support frame 208 and outer ring fixing member 209, the filling seat (lifting component 202, moving component 203, weighing base plate 204, cantilever beam load cell 205, weighing bracket 206 and soft rubber seal 207, etc.) can be removed from the filling fixing plate 101 as a whole. Only the connection between the support frame 208 and the filling fixing plate 101 needs to be removed, making the maintenance, cleaning, replacement or upgrading of the equipment more convenient and quick, and reducing maintenance costs and time costs.

[0034] Please see Figure 14In one embodiment, the top circumferential surface of the fixed outer ring 2071 is provided with a plurality of first fixing posts 20711, and the bottom circumferential surface of the outer ring fastener 209 is provided with a plurality of first fixing holes 2091 that mate with the first fixing posts 20711. 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 fastener 209 is achieved, simplifying the installation process, improving assembly efficiency, and ensuring the firmness of the connection.

[0035] Please see Figure 12 , Figure 13 In one embodiment, the four corners of the support frame 208 are fixed to the filling fixing plate 101 by wing screws 210. The wing screws 210 are easy to tighten and loosen manually, and can be installed and adjusted without special tools, which greatly facilitates the maintenance and upgrading of the equipment.

[0036] Please see Figure 3 , Figure 4 , Figures 12 to 14 In one embodiment, a filling sealing disc 211 is provided around the filling head 201. The filling sealing disc 211 is fixed to the bottom of the weighing base plate 204. A first filling sealing gasket 2014 surrounds the bottom of the filling sealing disc 211. A fixing inner ring 2072 is fixed to the bottom of the filling sealing disc 211 by an inner ring silicone pressure plate 212. The combination of the filling sealing disc 211 and the first filling sealing gasket 2014 ensures a good seal between the filling head 201 and the wine tank, preventing leakage and contamination during the filling process.

[0037] Specifically, the inner ring silicone pressure plate 212 has multiple second fixing posts 2121 arranged circumferentially on its top, and the inner ring 2072 has multiple openings 20721 circumferentially for the second fixing posts 2121 to pass through. The bottom of the filling sealing plate 211 has multiple second fixing holes 2111 that mate with the second fixing posts 2121. The inner ring silicone pressure plate 212 is firmly fixed to the bottom of the filling sealing plate 211 through the cooperation of the second fixing posts 2121 and the second fixing holes 2111, while pressing and fixing the inner ring 2072. This ensures a tight connection between the soft rubber seal 207 and the weighing base plate 204, and facilitates easy installation and disassembly, simplifying the installation process and improving assembly efficiency.

[0038] In one embodiment, the deformation groove 2073 has a U-shaped cross-section. This deformation groove 2073 allows the soft rubber seal 207 to have a certain deformation space when subjected to pressure, thereby better adapting to minor displacements and weight during the filling process, maintaining the sealing effect while also increasing the durability and lifespan of the seal.

[0039] Please see Figure 3 , Figure 4 , Figure 12 , Figure 13 In one embodiment, the lifting assembly 202 includes a power source 2021, a guide assembly 2022, and two guide shafts 2023. The power source 2021 is fixed to the weighing base plate 204. The driving end of the power source 2021 is connected to the guide assembly 2022 and drives the guide assembly 2022 to rise and fall. The tops of the two guide shafts 2023 are respectively fixed to both ends of the guide assembly 2022, and their bottoms are respectively fixed to both ends of the moving assembly 203. Simultaneously, the weighing base plate 204, the fixing inner ring 2072 of the soft rubber seal 207, the filling sealing plate 211, and the inner ring silicone pressure plate 212 are respectively fitted onto the two guide shafts 2023, which can further enhance the stability of the movement of the guide shafts 2023. In this embodiment, the power source 2021 is driven by an electric cylinder, but a cylinder or other mechanism capable of providing power can also be used. Driven by the electric cylinder, the guide assembly 2022 moves upward, which in turn drives the guide shaft 2023 and the moving assembly 203 containing or fitted with the container to move upward until the opening of the container reaches the filling sealing disc 211, which then seals the opening of the container.

[0040] Please see Figure 4 , Figure 5 In one embodiment, the moving assembly 203 includes a support plate 2031, with both ends of the support plate 2031 fixed to the bottom of two guide shafts 2023. The support plate 2031 is used to support the cup container and ensure that the cup container is aligned with the center of the filling head 201 during filling. The dimensions of the support plate 2031 are designed according to the specifications of the cup container. In addition, to be compatible with both cup and bottle containers, the lower middle ends of the two guide shafts 2023 are provided with hanging plate grooves 20231. The moving assembly 203 also includes a bottle mouth hanging plate 2032 and two separate clamping sleeves 2033. The bottle mouth hanging plate 2032 has a U-shaped opening 20321 in the center of its front side, which is used to clamp the bottle mouth of the bottle container. Both ends of the bottle mouth hanging plate 2032 are provided with U-shaped mounting grooves 20322 that cooperate with the hanging plate grooves 20231. When filling cup containers, it is not necessary to install the bottle mouth hanging plate 2032. When filling bottled containers, hang the two ends of the bottle mouth hanging plate 2032 on the hanging plate grooves 20231 of the two guide shafts 2023 through the U-shaped mounting grooves 20322, and lock them on the two guide shafts 2023 respectively through the two separation clamping sleeves 2033.

[0041] Please see Figure 12In one embodiment, the guide component 2022 is equipped with a sensor 213 for detecting whether a container is placed on the moving component 203 and for identifying the container type. This allows the power source 2021 to adjust the filling and sealing force according to the container type identified by the sensor 213, ensuring that each type of container receives a suitable seal, thereby guaranteeing filling quality and avoiding problems such as leakage due to insufficient sealing or container deformation due to excessive sealing. Due to the differences in the opening diameter and shape of cup containers and bottle containers, different filling and sealing forces are required, with cup containers requiring a greater sealing force than bottle containers. Using the same filling and sealing force for both can easily lead to insufficient sealing for cup containers, resulting in inability to fill properly, or excessive sealing force for bottle containers, causing deformation.

[0042] Please see Figure 3 In one embodiment, the dual waste liquid exhaust assembly includes a primary waste liquid tank 301 for gas-liquid separation and a secondary waste liquid tank 302 for gas filtration. The air and liquid inlet of the primary waste liquid tank 301 is connected to the exhaust and liquid outlet connector 2016 of the filling head 201. The exhaust port of the primary waste liquid tank 301 is connected to the air inlet of the secondary waste liquid tank 302. The exhaust port of the secondary waste liquid tank 302 is connected to an exhaust valve. The secondary waste liquid tank 302 stores clean water. The gas (carbon dioxide) discharged from the primary waste liquid tank 301 passes through the clean water and is discharged from the exhaust port of the secondary waste liquid tank 302. The clean water in the secondary waste liquid tank 302 can filter the incoming gas, dissolving impurities (such as alcohol mist) in the gas 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 wine may enter the vent and drain connector 2016 of the filling head 201 after filling, in order to prevent the wine from entering the secondary waste liquid tank 302 and affecting the filtration of the clean water, a primary waste liquid tank 301 needs to be set up before the secondary waste liquid tank 302 for gas-liquid separation.

[0043] Please see Figure 1 , Figure 2 In one embodiment, the front of the cabinet 1 is provided with a transparent cabinet door 102 and an operation display screen 103. The transparent cabinet door 102 is provided corresponding 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 order food and make payments.

[0044] In one embodiment, the present invention also provides a filling sealing force control method, applied to the filling apparatus of any of the above embodiments, comprising: The sensor 213 determines whether a cup or bottle container is placed on the moving component 203 based on the detection result of the sensor 213. The sensor 213 detects the movement distance of the moving component 203 based on the time of receiving the feedback signal. If sensor 213 receives a feedback signal within the first preset time period, it determines that a cup container is placed on the moving component 203, and seals the opening of the cup container with the first filling sealing force. If sensor 213 receives a feedback signal within the second preset time period, it determines that a bottled container is placed on the moving component 203, and seals the opening of the bottled container with the second filling sealing force. If the sensor 213 does not receive a feedback signal within the third preset time period, it is determined that no cup or bottle container is placed on the moving component 203, and the user is reminded that no cup or bottle container has been placed or has not been placed correctly.

[0045] Since the speed at which the power source 2021 drives the moving component 203 is constant, and the time it takes for the power source 2021 to drive different types of containers (the distance between the opening of different types of containers and the filling head 201 is different when they are placed or hung on the moving component 203) to the filling head 201 is different, it is possible to determine whether there is a cup container or a bottle container on the moving component 203, and whether there is no cup container or bottle container on the moving component 203, based on the time when the sensor 213 receives the feedback signal.

[0046] By employing the aforementioned filling and sealing force control method, the automatic identification of container type (cup or bottle) and corresponding adjustment of the filling and sealing force reduces the time spent on manual adjustments, thereby improving overall filling efficiency. Automatic sealing force adjustment ensures a suitable sealing effect for each container, guaranteeing filling quality and preventing problems such as leakage due to insufficient sealing or container deformation due to excessive sealing. In traditional filling processes, operators need to manually determine the container type and adjust the sealing force, which is prone to errors. This control method, through automatic detection and judgment by sensor 213, significantly reduces the possibility of human error and enhances the level of intelligence. Furthermore, when sensor 213 detects an unplaced or incorrectly placed container, it alerts the user, helping them correct errors promptly and preventing filling failures due to improper operation, thus improving the user experience.

[0047] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0048] The present invention has been described above with reference to the accompanying drawings. Obviously, the implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other situations without modification, are all within the protection scope of the present invention.
