Technical Field

[0001] The embodiments of the present invention relate to the technical field of filling equipment, and in particular to a filling system and a filling method. Background Art

[0002] Existing filling methods are limited to filling empty bottles of the same type and similar capacity.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It will be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all structures.

[0036] An embodiment of the present invention provides a filling system. Figure 1 FIG. 1 is a structural diagram of a filling system provided by an embodiment of the present invention. Figure 1 As shown, the filling system 10 includes a control module 110 , a filling switching module 120 and a filling module 130 ;

[0037] The control module 110 includes a control information output terminal A, the filling switching module 120 includes a control information receiving terminal B and a switching information output terminal C, and the filling module 130 includes a switching information receiving terminal D;

[0038] The control information output terminal A is electrically connected to the control information receiving terminal B, and the switching information output terminal C is electrically connected to the switching information receiving terminal D; the filling switching module 120 is used to control the filling module 130 to operate in the first filling mode or the second filling mode according to the control information output by the control module 110;

[0039] Among them, the first filling mode includes a coarse filling mode and a fine filling mode, which are used to fill the first container; the second filling mode includes a fine filling mode, which is used to fill the second container; the filling flow rate of the coarse filling mode is greater than the filling flow rate of the fine filling mode, and the capacity of the first container is greater than the capacity of the second container.

[0040] The filling system 10 provided by the embodiment of the present invention includes a control module 110, a filling switching module 120, and a filling module 130. Specifically, the control module 110 includes a control information output terminal A, the filling switching module 120 includes a control information receiving terminal B and a switching information output terminal C, and the filling module 130 includes a switching information receiving terminal D. The control information output terminal A is electrically connected to the control information receiving terminal B for transmitting control signals between the control module 110 and the filling switching module 120. The switching information output terminal C is electrically connected to the switching information receiving terminal D for transmitting switching information between the filling switching module 120 and the filling module 130, enabling the filling switching module 120 to adjust the operating mode of the filling module 130. The filling module 130 can provide two operating modes for the filling system 10, including a first filling mode and a second filling mode. The filling switching module 120 is configured to control the filling module 130 to operate in either the first filling mode or the second filling mode based on the control information output by the control module 110.

[0041] Specifically, the first filling mode includes a coarse filling mode and a fine filling mode, and the second filling mode includes a fine filling mode. Specifically, the coarse filling mode provides a high flow rate when filling a container, while the fine filling mode provides a low flow rate when filling a container. The filling flow rate in the coarse filling mode is greater than that in the fine filling mode. For example, if a container to be filled is N liters, the coarse filling mode can complete the filling in 1 minute, while the fine filling mode requires 5 minutes to complete the filling.

[0042] Furthermore, the first filling mode is used to fill the first container M1 (not shown in the figure), and adopts a working mode that combines the coarse filling mode and the fine filling mode. The second filling mode is used to fill the second container M2 (not shown in the figure), and adopts a working mode that combines the coarse filling mode and the fine filling mode. Among them, the capacity of the first container M1 is greater than the capacity of the second container M2. Exemplarily, when the container capacity is small, the filling can be completed by only adopting the working mode of the fine filling mode, and the accuracy and speed of the filling can be guaranteed; when the container capacity is large, the working mode that combines the coarse filling mode and the fine filling mode is adopted, which can improve the filling speed while ensuring the accuracy of the filling. The installation method of the filling system 10 provided in the embodiment of the present invention adopts the guide rail installation method of the prior art. This embodiment maximizes the function with minimal adjustment, and the guide rail installation method can be a 35mm guide rail installation method.

[0043] In summary, the filling system provided by the embodiment of the present invention controls the filling module to operate in the first filling mode or the second filling mode according to the control information output by the control module through the filling switching module, wherein the first filling mode includes a coarse filling mode and a fine filling mode, which are used to fill the first container; the second filling mode includes a fine filling mode, which is used to fill the second container, and the filling flow rate of the coarse filling mode is greater than the filling flow rate of the fine filling mode, and the capacity of the first container is greater than the capacity of the second container. Different containers are controlled by the filling switching module to quickly switch the working mode of the filling module, which solves the problem of a single working mode and realizes that containers of different capacities have suitable filling working modes. At the same time, when the capacity difference between containers is large, the appropriate filling working mode can be switched to ensure the speed and accuracy of filling, thereby improving the efficiency of filling.

[0044] Based on the above embodiment, the capacity of the first container M1 is greater than 1200 ml, and the capacity of the second container M2 is less than or equal to 350 ml.

[0045] The capacity of the first container M1 and the second container M2 differ significantly. The capacity of the first container M1 is greater than 1200 ml. For example, the capacity of the first container M1 may be 1200 ml, 1300 ml, or even greater. The capacity of the second container M2 is less than or equal to 350 ml. For example, the capacity of the second container M2 may be 350 ml, 250 ml, or even less. This allows the filling system 10 to be suitable for filling containers with significantly different capacities, thereby improving the universality of the filling system 10.

[0046] Figure 2 FIG. 1 is a structural diagram of another filling system provided by an embodiment of the present invention. Figure 2 As shown, the filling module 130 includes a filling main circuit 135 and n filling branches 136, where n is a positive integer;

[0048] The first switching control unit 121 includes a control information receiving terminal B and a first control information transmitting terminal B1, and the second switching control unit 122 includes a second control information transmitting terminal B2 and a switching information output terminal C; the first control information transmitting terminal B1 is electrically connected to the second control information transmitting terminal B2.

[0049] Specifically, the filling module 130 includes a filling main circuit 135 and n filling branches 136, where n is a positive integer. The filling switching module 120 includes a first switching control unit 121 and n second switching control units 122. Figure 2 As shown, the first switching control units 121 are arranged in series in the filling main circuit 135, and any second switching control unit 122 is arranged in series in a filling branch circuit 136. Here, n can be 2, 4, 7, 9, etc. The specific number of filling branches 136 and the number of second switching control units 122 are not limited in this embodiment of the present invention. However, there is a one-to-one correspondence between the second switching control units 122 and the filling branches 136, ensuring that each second switching control unit 122 is arranged in series in a filling branch 136.

[0050] Furthermore, the first switching control unit 121 includes a control information receiving terminal B and a first control information transmission terminal B1, and the second switching control unit 122 includes a second control information transmission terminal B2 and a switching information output terminal C. The first control information transmission terminal B1 is electrically connected to the second control information transmission terminal B2 to enable transmission of switching information between the first switching control unit 121 and the second control information transmission terminal B2. For example, the first switching control unit 121 and the second switching control unit 122 can be switch control elements. By turning the switch control elements on and off, the switching information is controlled step by step, thereby switching the operating mode of the filling system 10 and improving the filling accuracy of the filling system 10.

[0051] The following description will be made by taking as an example that the first switching control unit and the second switching control unit are both relays.

The second normally open contact 1221B includes a switching information output terminal C for transmitting switching information. This layer-by-layer transmission of control information ensures the switching of operating modes of the filling system 10 and improves the filling accuracy of the filling system 10.

[0056] Continue to refer Figure 2 As shown, any filling branch 136 includes a coarse filling solenoid valve 137 and a fine filling solenoid valve 138;

[0057] The control information includes first control information and second control information;

[0058] The first coil 1211A is configured to be energized according to the first control information, and the first normally open contact 1211B is configured to be closed according to the first control information. The second coil 1221A is configured to be energized according to the first control information, and the second normally open contact 1221B is configured to output first switching information according to the first control information, so as to operate the coarse filling solenoid valve 137 and the fine filling solenoid valve 138.

[0059] The first coil 1211A is also used to lose power according to the second control information, the first normally open contact 1211B is also used to disconnect according to the second control information, the second coil 1221A is also used to lose power according to the second control information, and the second normally open contact 1221B is also used to output second switching information according to the second control information to enable the fine filling solenoid valve 138 to work.

[0060] Each filling branch 136 includes a coarse filling solenoid valve 137 and a fine filling solenoid valve 138. Solenoid valves are electromagnetically controlled industrial devices and are fundamental automation components used to control fluids. The coarse filling solenoid valve 137 controls the opening and closing of the coarse filling mode, while the fine filling solenoid valve 138 controls the opening and closing of the fine filling mode.

[0061] The control information includes first control information and second control information. The first control information controls the filling switching module 120 to output first switching information, further controlling the filling module 130 to execute the coarse filling mode and the fine filling mode; the second control information controls the filling switching module 120 to output second switching information, further controlling the filling module 130 to execute the fine filling mode.

[0062] Specifically, the first coil 1211A is energized according to the first control information, the first normally open contact 1211B is closed according to the first control information, and the first switching control unit 121 transmits the first control information to the second switching control unit 122. The second coil 1221A is energized according to the first control information, the second normally open contact 1221B is output first switching information according to the first control information, the second switching control unit 122 transmits the first switching information, the coarse filling solenoid valve 137 and the fine filling solenoid valve 138 operate, and the filling system 10 executes the coarse filling mode and the fine filling mode.

The first switching control unit 121 transmits the second control information to the second switching control unit 122. The second coil 1221A is configured to de-energize based on the second control information, and the second normally open contact 1221B is configured to output second switching information based on the second control information. The second switching control unit 122 transmits the second switching information, causing the fine filling solenoid valve 138 to operate, and the filling system 10 to enter the fine filling mode. The filling system provided in this embodiment of the present invention generates different switching information based on the transmission of the first and second control information, controlling the opening and closing of the coarse filling solenoid valve 137 and the fine filling solenoid valve 138, and thus controlling the execution of different operating modes.

[0064] Based on the above embodiment, the first relay 1211 includes a terminal-type relay; the second relay 1221 includes a terminal-type relay.

[0065] The first relay 1211 comprises a terminal-type relay, and the second relay 1221 comprises a terminal-type relay. Terminal-type relays can save space in the filling system 10. Considering space and cost considerations in the filling system 10, the first relay 1211 and the second relay 1221 can be ultra-thin terminal-type relays. Ultra-thin terminal-type relays are thin, require smaller mounting components, can handle higher currents, and are less susceptible to burnout.

[0066] Based on the above embodiment, the terminal size of the terminal-type relay is 1-10 mm.

[0067] The size of the terminal type relay is 1-10 mm, and may be 5 mm. The embodiment of the present invention does not impose any specific limitation on the size of the terminal type relay. The use of the terminal type relay can save space in the filling system 10.

Adding a touch button on the touch screen simplifies the operation process, reduces the workload of the operator, and better realizes production automation. The control unit 112 includes a programmable logic controller. A programmable logic controller (PLC) is a digital operation controller with a microprocessor for automatic control.
