[0002] Liquid filling is a key step in the production process in industries such as pharmaceuticals, food and cosmetics. Traditional BFS (Blow-Fill-Seal) aseptic filling machines are widely used in these industries to accurately fill liquid products into containers and ensure that the entire process meets aseptic requirements.

[0003] In existing BFS aseptic filling machines, a single liquid filling path or a fixed multi-path design is usually adopted.

The filling switching movable housing 17 drives the filling pipe component to switch the connection with the interface at the top of the filling needle 9. The bottom end of the filling liquid box 3 is fixedly connected to the filling platform 1 through two supporting columns 2.

[0024] In this embodiment, a rectangular opening is provided on one side of the filling switching movable housing 17 and on the top surface of the L-support vertical plate 7, and the filling lifting plate 12 is adapted to be disposed in the rectangular opening.

[0025] In this embodiment, an inverted L bracket 10 is welded on one side of the filling lifting plate 12 and on the top surface of the L supporting vertical plate 7. An electric lifting column 11 is fixedly installed in the middle position of the inner top wall of the L bracket 10. The bottom lifting end of the electric lifting column 11 is connected to the top surface of the filling lifting plate 12 by bolts.

[0026] In this embodiment, when the electric lifting column 11 drives the filling lifting plate 12 to descend, the filling lifting plate 12 drives the plurality of filling needles 9 to descend, so that the filling needles 9 are inserted into the containers to be filled.

[0027] In this embodiment, a first fixed plate 14 is welded to the top surface of the L-support vertical plate 7 and close to one side of the filling switching movable shell 17. The top end of each filling needle 9 longitudinally penetrates to the outside above the filling lifting plate 12 and is connected to a second branch hose 13.

[0031] In this embodiment, a limiting rod 30 is welded on one side of the L movable plate 15 and located on the outer wall of the L supporting vertical plate 7 . A first positioning rod 21 is welded on the outer wall of one side of the L movable plate 15 , and the first positioning rod 21 passes through the limiting rod 30 . When it is necessary to switch the path, the cylinder member 20 first pulls the filling switching movable housing 17 backward and disengages from the first fixed plate 14. When the filling switching movable housing 17 retreats, it drives the L movable plate 15 to slide and rub against the outer wall of the L supporting vertical plate 7 and retreat. At this time, the first positioning rod 21 telescopically moves in the limiting rod 30 to support and position the L movable plate 15. When the filling switching movable housing 17 is separated from the first fixed plate 14, the electric push-pull rod 22 is opened to push and pull the filling switching movable housing 17, so that the filling switching movable housing 17 moves along the telescopic direction of the electric push-pull rod 22. When the plug-in pipe connector 25 is aligned with the interface of the second branch hose component 13 on the first fixed plate 14 to be docked, the push-pull action of the electric push-pull rod 22 is stopped. At this time, the cylinder member 20 pushes the filling switching movable housing 17 to fit onto the outer wall of the first fixed plate 14, so that the plug-in pipe connector 25 is clamped to the interface of the second branch hose component 13 on the first fixed plate 14 of the desired docking switching path, thereby completing the switching path.

[0032] In this embodiment, a plug-in positioning rod 23 is welded on one side of the electric push-pull rod 22 and located on the inner wall of the L movable plate 15, and a positioning hole 27 is opened on the inner wall of the filling switching movable housing 17, and the plug-in positioning rod 23 is inserted into the positioning hole 27. When the electric push-pull rod 22 drives the filling switching movable housing 17 to move, the plug-in positioning rod 23 can position the movement of the filling switching movable housing 17 to prevent the movement from tilting. A plurality of upper joints 24 are equidistantly embedded in the top surface of the filling switching movable housing 17, and a plurality of plug-in pipe joints 25 are equidistantly embedded in the outer wall of the filling switching movable housing 17 on one side facing the first fixed plate 14, each plug-in pipe joint 25 is connected through the corresponding upper joint 24 above, and the filling pipe component includes a first branch hose component 6 sealedly connected to each upper joint 24, and each first branch hose component 6 is sealedly connected to the corresponding branch valve tube 5, so that when the solenoid valve inside each branch valve tube 5 is opened by the PLC, the filling liquid in each corresponding liquid cavity in the filling liquid box 3 flows into the corresponding upper joint 24 through the corresponding first branch hose component 6, and then flows from the upper joint 24 into the plug-in pipe joint 25, and through the moving switching path of the filling switching movable housing 17, the filling liquid in the plug-in pipe joint 25 flows into the interface of the second branch hose component 13 on the first fixed plate 14 of the required switching path, thereby completing the switching of filling paths of different filling liquids, and a sealing gasket 26 is provided at the free end of each plug-in pipe joint 25.

[0033] Working principle: The BFS aseptic filling machine device with a mechanism for switching the filling path, the operator starts the BFS aseptic filling machine device, all control systems such as PLC are initialized, and all components are checked to see if they are working properly. The flip cover 4 is opened, and different types of filling liquids are poured into the respective liquid cavities in the filling liquid box 3. The containers to be filled are placed on the conveyor 8, ready for automatic filling. The conveyor 8 is started, and the containers to be filled are conveyed to the predetermined filling positions in sequence. When the container reaches the filling position, the conveyor 8 stops to ensure that the container is accurately aligned with the filling needle 9.

[0034] According to the type of liquid to be filled, the operator or the control system selects the corresponding branch valve tube 5. At this time, the oil cylinder 20 pulls the filling switching movable housing 17 to retreat along the Y-axis direction and detach from the first fixed plate 14. As the filling switching movable housing 17 retreats, the L movable plate 15 slides and rubs on the outer wall of the L support vertical plate 7 and retreats. At the same time, the first positioning rod 21 telescopically moves in the limit rod 30 to provide support and positioning. The electric push-pull rod 22 drives the filling switching movable housing 17 to move along the X-axis direction, so that the plug-in pipe connector 25 is aligned with the interface of the second branch hose component 13 on the first fixed plate 14 to be docked.

[0035] When the plug-in tube connector 25 is aligned with the interface of the second branch hose 13, the cylinder 20 pushes the filling switching movable housing 17 to fit the outer wall of the first fixed plate 14, so that the plug-in tube connector 25 is snapped onto the corresponding interface to complete the path switching. The PLC control system opens the solenoid valve inside the selected branch valve tube 5, allowing the liquid to flow out of the corresponding liquid cavity. The liquid enters the upper connector 24 through the first branch hose 6, and then flows into the filling needle 9 through the plug-in tube connector 25. The electric lifting column 11 drives the filling lifting plate 12 to descend, driving multiple filling needles 9 to be inserted into the container. The liquid is accurately injected into the container through the filling needle 9, and the filling amount is strictly monitored by the control system to ensure that the filling amount of each container is consistent.

[0036] When the liquid in the container reaches a predetermined amount, the PLC control system closes the solenoid valve to stop the liquid flow. The electric lifting column 11 drives the filling lifting plate 12 to rise, and pulls the filling needle 9 out of the container to prevent liquid dripping.

[0037] The conveyor 8 restarts, moves the filled containers out of the filling area, and the new containers to be filled are sent to the filling position. The whole process is repeated until all containers are filled. When running for a long time or changing different types of filling liquids, the operator can open the flap 4 to clean the filling liquid box 3 and related pipes to prevent cross contamination. Regularly check the working status of each component, such as the sealing of the sealing gasket 26 and the lubrication of the electric lifting column 11, to ensure long-term and stable operation of the equipment.
