[0012] S6. Capping: The capping component moves back to the top of the medicine bottle and caps it onto the bottle body;

[0013] S7. Capping: The capping component moves to the top of the medicine bottle to cap it.

[0014] As a further improvement to the above technical solution: the cap-removing and cap-fastening component, the filling component, the stopper-removing and stopper-placing component, and the cap-pressing component are all located on the same driving component.

[0015] As a further improvement to the above technical solution, the following steps are also included:

[0016] S8. Light inspection: The robotic arm transfers the medicine bottle to the light inspection station for light inspection;

[0017] S9. Labeling: The robotic arm transfers the medicine bottles to the bottle transfer mechanism, which then transfers the medicine bottles to the labeling station for labeling.

[0018] S10, Discharge: The medicine bottle falls into the discharge station to complete the discharge.

[0019] As a further improvement to the above technical solution, the detailed steps of step S4 are as follows:

[0020] S4.1 Empty bottle weighing: The medicine bottle is placed completely on the weighing platform and supported by the platform, and the weighing sensor weighs it.

[0021] S4.2 Online filling and weighing: The filling component moves above the medicine bottle to fill the medicine, and the weighing sensor weighs the contents until the filling amount reaches the set value.

[0022] S4.3 Medicine bottle transfer: Separate the medicine bottle from the weighing stand.

[0023] A filling and capping integrated device includes a support component, a medicine bottle clamping and positioning mechanism, and a rotatable and liftable drive component. The medicine bottle clamping and positioning mechanism and the drive component are both located on the support component. The medicine bottle clamping and positioning mechanism is located below the drive component. The drive component is provided with a filling component, a stopper removal and placement component, a cap removal and cap fastening component, and a capping component.

[0024] As a further improvement to the above technical solution, a weighing component is also included, which is located below the medicine bottle clamping and positioning mechanism.

[0025] As a further improvement to the above technical solution: the supporting component is provided with a liftable support component, the medicine bottle clamping and positioning mechanism is provided on the support component, the weighing component includes a weighing sensor and a scale support provided on the weighing sensor, and the support component is provided with a channel for the scale support to pass through.

[0026] As a further improvement to the above technical solution: the support component is a sealed chamber structure, and the support component is provided with a first power source for driving the drive component to rise and rotate, and a second power source for driving the support component to rise and rotate.

[0029] Compared with the prior art, the advantages of the present invention are as follows: In the filling method disclosed in the present invention, the medicine bottle remains stationary throughout the entire process from cap removal to cap crimping after it is in place. The corresponding processes are completed by the actions of the cap removal and cap crimping component, the stopper removal and stopper placement component, the filling component, and the cap crimping component. Therefore, there is no need to set up a medicine bottle transport mechanism, which helps to simplify the structure and reduce costs. Furthermore, the stationary medicine bottle is easy to weigh and fill simultaneously, ensuring filling accuracy. Compared with the solution where the medicine bottle moves while the cap removal and cap crimping component remains stationary, the present invention is not limited by the medicine bottle transport speed (the transport speed of the medicine bottle after filling should not be too fast), which helps to improve production efficiency.

[0030] The filling and capping integrated device disclosed in this invention integrates the filling component, the stopper picking and placing component, the cap picking and capping component, and the capping component on the driving component. The overall structure is more compact, occupies less space, and is convenient for protection. The driving component drives each execution component to complete the corresponding process. The medicine bottle does not need to be moved. Therefore, there is no need to set up a medicine bottle transfer mechanism, the structure is simpler, and the cost is lower.

[0040] Example 1

[0041] Figures 1 to 2 An embodiment of the filling method of the present invention is shown. The filling method of this embodiment includes the following steps:

[0042] S1. Medicine bottle 300 in place: The robot arm 200 transfers the medicine bottle 300 with the stopper 302 and the cap 303 to the filling and capping station 101;

[0043] S2. Remove cap: The cap removal and buckle component 6 moves to above the medicine bottle 300 and removes the bottle cap 303;

[0044] S3, Stopper Removal: The stopper removal and placement component 5 moves to above the medicine bottle 300 and removes the stopper 302;

[0045] S4. Filling: The filling component 4 moves to above the medicine bottle 300 to perform filling;

[0046] S5, Stopper Placement: The stopper removal and placement component 5 moves again above the medicine bottle 300 and places the stopper 302 on the bottle body 301;

[0047] S6. Capping: The capping component 6 moves again to above the medicine bottle 300 and caps the bottle cap 303 onto the bottle body 301;

[0048] S7, Capping: The capping component 7 moves to above the medicine bottle 300 to cap it.

[0049] In this embodiment of the filling method, after the medicine bottle 300 with stopper 302 and cap 303 is in place, it remains stationary throughout the entire process from cap removal to cap crimping. The corresponding processes are completed by the actions of the cap removal and cap crimping component 6, the stopper removal and placement component 5, the filling component 4, and the cap crimping component 7. Therefore, there is no need to set up a medicine bottle transport mechanism, which helps to simplify the structure and reduce costs. Furthermore, the stationary medicine bottle 300 is easy to weigh and fill simultaneously, ensuring filling accuracy. Compared with the solution where the medicine bottle 300 moves while the cap removal and cap crimping component 6 remains stationary, this invention is not limited by the transport speed of the medicine bottle 300 (the transport speed of the medicine bottle 300 after filling should not be too fast, otherwise it will easily cause the medicine to shake), which helps to improve production efficiency.

[0050] Furthermore, in this embodiment, the cap-removing and cap-fastening component 6, the filling component 4, the stopper-removing and stopper-placing component 5, and the cap-pressing component 7 are all mounted on the same driving component 3. Concentrating these components on the same driving component 3 improves integration and makes the overall structure simpler and more compact. In this embodiment, the driving component 3 is a liftable and rotatable turntable. However, in other embodiments, the driving component 3 can also be a linear component that can be lifted and reciprocated, with the cap-removing and cap-fastening component 6, the filling component 4, the stopper-removing and stopper-placing component 5, and the cap-pressing component 7 arranged in a straight line at intervals.

[0051] Furthermore, in this embodiment, the filling method further includes the following steps:

[0052] S8. Light inspection: Robotic arm 200 transfers medicine bottle 300 to light inspection station 104 for light inspection;

[0053] S9. Labeling: The robot arm 200 transfers the medicine bottle 300 to the bottle transfer mechanism 105, and the bottle transfer mechanism 105 transfers the medicine bottle 300 to the labeling station 106 for labeling. Preferably, the filling and capping station 101 and the light inspection station 104 are located in the upper area of ​​the filling chamber 100, while the labeling station 106 and the discharging station 107 are located in the lower area of ​​the filling chamber 100. This helps to prevent the micro-dust generated during labeling and discharging from spreading to the upper area and causing pollution risk, thus ensuring the high cleanliness of the upper area.

[0054] S10, Discharge: Medicine bottle 300 falls into discharge station 107 to complete discharge.

[0055] Furthermore, in this embodiment, the detailed steps of step S4 are as follows:

[0056] S4.1 Empty bottle weighing: The medicine bottle 300 is completely placed on the weighing support 82 and supported by the weighing support 82. The weighing sensor 81 performs the weighing, which can avoid interference and ensure the accuracy of empty bottle weighing.

[0057] S4.2 Online filling and weighing: The filling component 4 moves above the medicine bottle 300 for filling, and the weighing sensor 81 weighs it until the filling amount reaches the set value. This realizes pre-filling and weighing, which helps to ensure the accuracy of the filling amount.

[0058] S4.3, Transfer of medicine bottle 300: The medicine bottle 300 is separated from the weighing tray 82. Except for the filling process, the medicine bottle 300 does not come into contact with the weighing tray 82 in other processes, or in other words, other processes are not carried out on the weighing tray 82, which helps to prevent affecting the accuracy of the weighing component 8 or even causing damage (the weighing sensor 81 in the weighing component 8 is a precision component).

[0059] Example 2

[0060] Figures 3 to 7 An embodiment of the filling and capping integrated device of the present invention is shown. The filling and capping integrated device of this embodiment includes a support component 1, a medicine bottle clamping and positioning mechanism 2, and a rotatable and liftable drive component 3. The medicine bottle clamping and positioning mechanism 2 and the drive component 3 are both disposed on the support component 1. The medicine bottle clamping and positioning mechanism 2 is located below the drive component 3. The drive component 3 is provided with a filling component 4, a stopper removal and placement component 5, a cap removal and cap fastening component 6, and a capping component 7.

[0061] In this embodiment, the integrated filling and capping device integrates the filling component 4, the stopper removal and placement component 5, the cap removal and capping component 6, and the capping component 7 onto the driving component 3. This results in a more compact overall structure, occupies less space, and facilitates protection. The driving component 3 drives each executing component (filling component 4, stopper removal and placement component 5, etc.) to complete the corresponding processes. The medicine bottle 300 does not need to move, thus eliminating the need for a medicine bottle 300 transport mechanism, leading to a simpler structure and lower cost. In this embodiment, the driving component 3 is a turntable. However, in other embodiments, the driving component 3 can also be a linear component capable of lifting, lowering, and reciprocating. The cap removal and capping component 6, the filling component 4, the stopper removal and placement component 5, and the capping component 7 are arranged in a straight line at intervals.

[0062] Furthermore, in this embodiment, the filling and capping integrated device also includes a weighing component 8, which is located below the bottle clamping and positioning mechanism 2. Except for the filling process, the bottles 300 are held and positioned by the bottle clamping and positioning mechanism 2 in all other processes, preventing the bottles 300 from contacting the weighing support 82. This helps prevent affecting the accuracy of the weighing component 8 or even causing damage. During the filling process, the bottle clamping and positioning mechanism 2 releases the bottle 300, allowing it to be easily transferred to the weighing component 8 for weighing. The structure is simple and effective.

[0063] Furthermore, in this embodiment, the support component 1 is provided with a liftable support component 9, the medicine bottle clamping and positioning mechanism 2 is provided on the support component 9, the weighing component 8 includes a weighing sensor 81 and a scale support 82 provided on the weighing sensor 81, and the support component 9 is provided with a channel 91 for the scale support 82 to pass through. Before the filling process, the supporting component 9 is in a high position, and correspondingly, the medicine bottle clamping and positioning mechanism 2 is also in a high position, with the medicine bottle 300 clamped and positioned by the medicine bottle clamping and positioning mechanism 2. During the filling process, the supporting component 9 drives the medicine bottle clamping and positioning mechanism 2 to descend to a low position, and the weighing support 82 passes through the channel 91 to support the medicine bottle 300. At this time, the medicine bottle clamping and positioning mechanism 2 completely releases the medicine bottle 300, and the weighing support 82 independently supports the medicine bottle 300, ensuring weighing accuracy and filling accuracy. After the filling process, the medicine bottle clamping and positioning mechanism 2 clamps the medicine bottle 300 again, and the supporting component 9 drives the medicine bottle clamping and positioning mechanism 2 to rise to a high position, separating the medicine bottle 300 from the weighing support 82 to avoid damaging the weighing sensor 81.

[0064] Furthermore, in this embodiment, the support component 1 is a sealed chamber structure. The support component 1 contains a first power source 11 for driving the drive component 3 to rise and rotate, and a second power source 12 for driving the support component 9 to rise and fall. The drive component 3 is connected to the first power source 11 via a first transmission shaft 31, and the support component 9 is connected to the second power source 12 via a second transmission shaft 92. The weighing sensor 81 is located inside the support component 1. The power source can be, for example, a common cylinder or motor. The support component 1 itself can provide protection for its internal components.

[0065] In a preferred embodiment, a first sealing seat 13 is provided between the first drive shaft 31 and the support component 1, a second sealing seat 14 is provided between the second drive shaft 92 and the support component 1, and a third sealing seat 15 is provided between the weighing support 82 and the support component 1, which helps to ensure the sealing of the inside of the support component 1.

[0066] In a preferred embodiment, the medicine bottle clamping and positioning mechanism 2 includes a pair of clamping plates 21 and a clamping drive component 22 (e.g., a cylinder) for driving the opening and closing of the pair of clamping plates 21. The clamping plates 21 are provided with medicine bottle positioning grooves 23 on their inner sides. The structure is simple and effective, and can conveniently clamp the medicine bottle 300. Furthermore, the clamping plates 21 and the clamping drive component 22 are detachably connected by bolts or the like, making it convenient to replace the clamping plates 21 to adapt to medicine bottles 300 of different sizes.

[0067] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
