[0003] Pharmaceutical enterprises need to set up different filling lines for different types of products during pilot production and production, and cannot use the same line, which greatly increases the cost of pharmaceutical enterprises. Chinese patent document CN116715179A discloses a filling machine, including a feeding module, a main filling module, a discharging module, a mold module, an inner cap feeding module and an outer cap feeding module. The discharging module and the mold module are arranged on a working line in sequence from left to right; the inner cap feeding module and the outer cap feeding module are connected to the main filling module, which can solve the problem that nasal sprays and eye drops cannot share the same line. The defect of this technical solution is that some modules need to be moved and docked, so the positioning accuracy requirement is relatively high. Otherwise, it is easy to cause broken bottles or equipment jams, and the structure is also relatively complex. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a filling and sealing production line with a simple structure, good reliability and capable of realizing co-line production of different types of products.

[0009] As a further improvement of the above technical solution: The filling device includes a walking beam, a rotatable fan-shaped bottle inlet block arranged upstream of the walking beam, and a rotatable fan-shaped bottle outlet block arranged downstream of the walking beam. There are bottle body positioning grooves on the walking beam, the fan-shaped bottle inlet block, and the fan-shaped bottle outlet block. The capping device is arranged on the side of the walking beam, and the screwing device is docked with the fan-shaped bottle outlet block.

[0010] As a further improvement of the above technical solution: The filling device further includes a first weighing component, a filling component, and a second weighing component arranged in sequence along the bottle conveying direction of the walking beam.

[0011] As a further improvement of the above technical solution: There is also an air washing component between the first weighing component and the filling component.

[0012] As a further improvement of the above technical solution: There is also a first nitrogen filling component between the air washing component and the filling component, and a second nitrogen filling component is arranged downstream of the second weighing component.

[0016] Compared with the prior art, the advantages of the present utility model are as follows: In the filling and capping production line disclosed by the present utility model, glass bottles and plastic bottles can be fed from the glass bottle feeding assembly and the plastic bottle feeding assembly respectively. After the filling device completes the filling of the bottle body, the inner cap component arranges the inner caps into columns and conveys them to the capping device. The first outer cap component arranges the press-in type outer caps into columns and conveys them to the capping device. The capping device presses the inner cap and / or the press-in type outer cap onto the bottle body. For the bottle bodies that need to be screwed with caps, the second outer cap component arranges the externally threaded outer caps into columns and conveys them to the capping device.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0031] Figures 2 to 6An embodiment of the filling and capping production line of the present utility model is shown. The filling and capping production line of this embodiment includes a filling device 2. Upstream of the filling device 2, there are a glass bottle feeding assembly 3 and a plastic bottle feeding assembly 4 connected. Downstream of the filling device 2, there are a capping device 5 and a screwing device 6 connected. There is an inner lid sorting component 51 and a first outer lid sorting component 52 on the side of the capping device 5, and a second outer lid sorting component 61 on the side of the screwing device 6. There is a variable pitch bottle discharging component 82 between the capping device 5 and the screwing device 6. The pitch of the end of the variable pitch bottle discharging component 82 close to the screwing device 6 is greater than the pitch of the end close to the capping device 5. Among them, the inner lid sorting component 51, the first outer lid sorting component 52, and the second outer lid sorting component 61 can be a plug sorting hopper, a cap sorting hopper, etc.

[0032] In the filling and capping production line of this embodiment, the glass bottles 12 and plastic bottles 15 can be fed from the glass bottle feeding assembly 3 and the plastic bottle feeding assembly 4 respectively. After the filling device 2 completes the filling of the glass bottles 12 and plastic bottles 15, the inner lid sorting component 51 sorts the inner lids (such as rubber plugs 14) into columns and conveys them to the capping device 5. The first outer lid sorting component 52 sorts the press-in type outer lids (such as press-in type pump heads 11 or bottle caps 13) into columns and conveys them to the capping device 5. The capping device 5 presses the inner lids and / or the press-in type outer lids onto the bottle body. For the bottle bodies that need to be screwed, the second outer lid sorting component 61 sorts the externally threaded outer lids (such as externally threaded pump heads 11 or bottle caps 13) into columns and conveys them to the screwing device 6. The screwing device 6 screws the outer lids onto the bottle body, which can realize the co-line production of products with multiple different capping types (products with different capping types are produced in batches, not mixed together). Moreover, the glass bottle feeding assembly 3 and the plastic bottle feeding assembly 4 are directly connected to the filling device 2 for feeding without moving for docking, with a simpler structure and better reliability, avoiding problems such as broken bottles and equipment jams. Since the cycle time of the screwing device 6 is generally slower than that of the capping device 5, the variable pitch bottle discharging component 82 can coordinate the cycle times of the two to keep the whole line running continuously and stably. Preferably, the capping device 5 is located upstream of the screwing device 6, which is beneficial to ensuring the production efficiency of most products with a capping type. For details, see Figure 5 ., and the variable pitch bottle discharging component 82 uses a bottle discharging auger. The pitch of the end of the auger close to the capping device 5 is smaller than the pitch of the end close to the screwing device 6. Of course, in other embodiments, the capping device 5 can also be arranged downstream of the screwing device 6.

[0033] For details, see Figure 2, Further, in this embodiment, the glass bottle feeding assembly 3 includes a bottle washer 31, a dryer 32, and a first bottle arranging component 33 that are connected in sequence. The bottle washer 31 cleans the glass bottles 12, and after the cleaning is completed, they are transported to the dryer 32 for drying and sterilization. After the glass bottles 12 are dried, they are transported to the first bottle arranging component 33 for buffering and sorting, and then are transported to the filling device 2 by means of a bottle conveying mesh belt or the like.

[0034] Even further, in this embodiment, the glass bottle feeding assembly 3 further includes a flipping air washing device 34, which is arranged between the first bottle arranging component 33 and the filling device 2. During the drying process of the glass bottles 12, there may be cases of bottle explosion or other reasons resulting in broken bottles. The flipping air washing device 34 can flip the glass bottles 12 so that the bottle mouths face downward and use high-speed air flow to blow out the glass residues inside the glass bottles 12, and finally flip the bottle bodies back to the upright state, thereby ensuring the cleanliness inside the glass bottles 12. Among them, the flipping air washing device 34 is an existing device and is mostly used for the cleaning of plastic bottles 15 (plastic bottles 15 cannot be dried at high temperatures, so water washing is not suitable).

[0035] Specifically refer to Figure 2 and Figure 4 , Further, in this embodiment, the filling device 2 includes a walking beam 21, a rotatable sector-shaped bottle inlet block 22 arranged upstream of the walking beam 21, and a rotatable sector-shaped bottle outlet block 23 arranged downstream of the walking beam 21. Bottle body positioning grooves are provided on the walking beam 21, the sector-shaped bottle inlet block 22, and the sector-shaped bottle outlet block 23. The capping device 5 is arranged on the side of the walking beam 21, and the cap screwing device 6 is docked with the sector-shaped bottle outlet block 23. The walking beam 21 cooperates with the sector-shaped bottle inlet block 22 and the sector-shaped bottle outlet block 23 upstream and downstream to stably and intermittently transport the bottle bodies, thereby realizing the high-speed cap screwing function.

[0036] Even further, in this embodiment, the filling device 2 further includes a first weighing component 24, a filling component 25, and a second weighing component 26 arranged in sequence along the bottle conveying direction of the walking beam 21. The first weighing component 24 can weigh the empty glass bottles 12 or plastic bottles 15 (i.e., weighing before filling). After the filling component 25 completes filling, the second weighing component 26 can weigh the filled bottle bodies. By calculating the difference between the two weighings before and after, the accurate filling volume can be obtained, and the structure is simple and effective.

[0037] Even further, in this embodiment, an air washing component 27 is further arranged between the first weighing component 24 and the filling component 25. The high-speed air flow generated by the air washing component 27 is used to blow out the possible impurities inside the plastic bottles 15, thereby ensuring the cleanliness inside the plastic bottles 15 before filling, and the structure is simple and reliable.

[0038] Furthermore, in this embodiment, a first nitrogen filling component 28 is also provided between the air washing component 27 and the filling component 25, and a second nitrogen filling component 29 is provided downstream of the second weighing component 26. The first nitrogen filling component 28 can be used to fill nitrogen before filling to displace the air inside the bottle, and the second nitrogen filling component 29 can be used to fill nitrogen after filling, thereby effectively controlling the residual oxygen content in the bottle and extending the storage time of the medicine.

[0039] Further, in this embodiment, a bottle inlet dial 7 is provided upstream of the sector-shaped bottle inlet block 22. The glass bottle feeding assembly 3 is connected to the bottle inlet dial 7 through a first bottle conveying channel 35, and the plastic bottle feeding assembly 4 is connected to the bottle inlet dial 7 through a second bottle conveying channel 41. By using the bottle inlet dial 7, it is convenient for the first bottle conveying channel 35 and the second bottle conveying channel 41 to be directly docked with it, simplifying the feeding structure of the glass bottles 12 and plastic bottles 15, which is beneficial to further improving the reliability and reducing the equipment cost.

[0040] Further, in this embodiment, the plastic bottle feeding assembly 4 includes two second bottle arranging components 42, and each second bottle arranging component 42 is respectively connected to the bottle inlet dial 7 through a second bottle conveying channel 41. Since the plastic bottles 15 are lighter in weight, the feeding speed is slower. By using two second bottle arranging components 42 and the corresponding second bottle conveying channels 41 for bottle feeding, it is beneficial to improve the feeding speed of the plastic bottles 15 and keep the production rhythm of the whole line consistent. Of course, in other embodiments, the number of the second bottle arranging components 42 can also be appropriately adjusted.

[0041] As a preferred embodiment, the second bottle arranging component 42 is an oscillating bottle arranging component (such as an oscillating bottle arranging hopper, etc.). The oscillating bottle arranging component is beneficial to improving the bottle arranging efficiency of the plastic bottles 15 and thus improving the feeding speed.

[0042] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make many possible changes and modifications to the technical solution of the present utility model by using the disclosed technical content without departing from the scope of the technical solution of the present utility model, or modify it into equivalent embodiments with equivalent changes. Therefore, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model without departing from the content of the technical solution of the present utility model shall fall within the scope of protection of the technical solution of the present utility model.
