Description

Technical Field

[0001] This utility model relates to the technical field of filling equipment in pharmaceutical machinery, and in particular to a rotary filling, nitrogen filling and stoppering device. Background Technology

[0002] As people's living standards continue to improve, customers have increasingly higher requirements for nitrogen-filled products, thus demanding higher levels of residual oxygen and dissolved oxygen in the final product. High-value-added products such as glucose, antibiotics, amino acids, fat emulsions, oral liquids, nutrient solutions, and biological agents have nitrogen gas filled into the gaps inside the bottles to extend their shelf life. This minimizes contact between air and the liquid, preventing chemical reactions between oxygen in the air and some active molecules in the liquid, which could lead to deterioration or changes in the composition of the drug.

[0003] The existing nitrogen filling and purging methods and equipment mainly include the following:

[0004] One method is to directly fill the bottle with nitrogen using a nitrogen tube, resulting in a residual oxygen content of approximately 3%, without requiring a specific dissolved oxygen level.

[0005] Because this method involves filling the bottle with nitrogen, the liquid medicine comes into full contact with the air inside the bottle during the filling process, resulting in a high dissolved oxygen concentration. Therefore, it is suitable for filling and purging products with nitrogen where the residual oxygen content of the final product is not critical.

[0006] The second step is to fill the empty bottle with nitrogen, then fill it with the contents while simultaneously filling it with nitrogen. Then, vacuum the bottle, fill it with nitrogen, vacuum the bottle again, and fill it with nitrogen again. Adjust the number of repetitions according to the effect, and finally seal the bottle with a stopper.

[0007] This method is suitable for filling nitrogen-filled products that require high residual oxygen content and high dissolved oxygen content in the final product, with a residual oxygen content of ≤1%. It is also the mainstream production process for nitrogen-filled products at present.

[0008] Moreover, this method involves forming a sealed cavity between multiple moving parts and the container holding the medicine during the entire nitrogen-filling process. This sealed cavity is then repeatedly evacuated and filled with nitrogen to displace the air inside the bottle, ultimately replacing all the air in the sealed cavity with nitrogen, thus preventing oxygen from contacting the medicine. This nitrogen-filling process has the following main disadvantages:

[0009] First, the equipment has a complex structure, high precision requirements, is difficult to manufacture, has complex program control, and requires highly skilled operators.

[0010] Secondly, the vacuum control of the two vacuum systems, vacuum pumping and vacuum plugging, is very complicated, and plugs are prone to falling off, resulting in a low plugging success rate.

[0011] Third, during vacuuming, the vapor generated by the liquid medicine can easily be drawn into the vacuum pipe. After condensation, it remains in the vacuum pipe, which can lead to excessive particulate matter in the pipe. When filling with nitrogen, the particulate matter in the pipe may be blown back into the bottle, thus affecting the quality of the medicine.

[0012] Fourth, the liquid medicine inside the bottle is prone to shaking during transportation, which will increase the concentration of dissolved oxygen.

[0013] Third, the empty bottle is filled with nitrogen, then immediately filled, and then filled with nitrogen again.

[0014] If this method is used at the same workstation, filling with nitrogen before filling will prolong the entire filling process, resulting in a decrease in production capacity per unit time. If it is used at two workstations, air will intrude during the transfer process, leading to an increase in dissolved oxygen in the solution.

[0015] Fourth, the empty bottle is filled with nitrogen, and then filled with nitrogen at the same time.

[0016] If this method is used at the same workstation, filling with nitrogen before filling and simultaneously filling with nitrogen will also prolong the entire process time, resulting in a decrease in production capacity per unit time. Similarly, if it is used at two workstations, the dissolved oxygen content in the liquid will increase due to air intrusion during the transfer process.

[0017] Chinese Patent (Patent Application No. 202222936646.3) discloses a "Nitrogen Filling System for a Benchtop Machine," which uses nitrogen filling to protect the liquid medicine during the filling and capping processes. The system is simple and easy to use. It includes a benchtop machine body, on which a filling assembly and a capping assembly are sequentially arranged along the production line. The filling assembly includes a needle holder with a filling needle, and a nitrogen filling needle that works with the filling needle on the needle holder. The capping assembly has a nitrogen filler, and a nitrogen curtain injector is located on the benchtop machine body between the filling assembly and the capping assembly.

[0018] Another Chinese patent (patent application number 202223346530.0) discloses a "nitrogen filling device for bottles before and after filling," which includes: a vent pipe, a vent seat, a gas distribution plate, a nitrogen filling nozzle, and a bottle support plate. The vent seat and the gas distribution plate are respectively arranged around the vent pipe, and are positioned vertically. The vent seat has a nitrogen channel, and the gas distribution plate has a nitrogen channel. The nitrogen channel of the vent seat connects the nitrogen outlet of the vent pipe to one end of the nitrogen channel of the gas distribution plate, and the other end of the nitrogen channel of the gas distribution plate is connected to the nitrogen filling nozzle. The outlet of the nitrogen filling nozzle is positioned directly opposite the bottle support plate, and there is an adjustable bottle height space between the outlet of the nitrogen filling nozzle and the bottle support plate. Compared with the prior art, this utility model has a simple structure, low cost, and is very convenient to install, adjust, use, and maintain. It has stable and reliable performance and does not affect the filling efficiency. Using this utility model, the bottle can be filled with nitrogen multiple times before and after filling, which can prevent the drug from being excessively oxidized due to prolonged contact with air, thus affecting the quality of the drug.

[0019] Another Chinese patent (patent application number 201510607536.4) discloses a "vacuum-filling nitrogen-pressing device and production line," which includes a sleeve shaft comprising a coaxial outer shaft and an inner shaft that can slide relative to each other. The outer shaft is connected to a first lifting device, and a sealing joint for sealing with the bottle body is provided at the lower end of the outer shaft. The inner shaft is connected to a second lifting device, and an air passage is provided on the inner shaft, with a stopper seat communicating with the air passage at the lower end. A sealing assembly is provided between the inner and outer shafts, and a vacuum-filling nitrogen-pressing interface is provided on the side wall of the outer shaft between the sealing assembly and the sealing joint. Therefore, the aforementioned vacuum-filling nitrogen-pressing device can form a small sealed space at the bottle mouth. Through repeated vacuuming and nitrogen filling operations, the residual oxygen level can be precisely controlled. Furthermore, after nitrogen filling, the stoppering operation is immediately performed in this sealed space, avoiding the reintroduction of oxygen during bottle transportation, reducing the defect rate, lowering production costs, and improving production efficiency. This invention also discloses a vacuum-filling nitrogen-pressing production line. Summary of the Invention

[0020] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a method and equipment for filling and filling nitrogen gas that is simple in process, low in operating cost, requires relatively small equipment area, and can significantly improve the quality of filled medicines.

[0021] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is to design a rotary filling and nitrogen-filling stoppering device: including a frame 9 and a bottle feeding mechanism 2, and further including a bottle separating mechanism 3, a nitrogen-filling and stoppering mechanism 4, a stopper sorting mechanism 1, and a stopper-taking, nitrogen-filling, and stoppering mechanism 8; the bottle feeding mechanism 2 is arranged in a left-right direction on the front side of the upper part of the frame 9, and the bottle separating mechanism 3 is arranged on the front right side of the bottle feeding mechanism 2; the nitrogen-filling and stoppering mechanism 4 is arranged on the rear right side of the bottle feeding mechanism 2 on the frame 9, and the stopper sorting mechanism 1 is arranged on its right side; the stopper-taking, nitrogen-filling, and stoppering mechanism 8 is arranged in the middle left part of the upper part of the frame 9, and its right side is connected to the nitrogen-filling and stoppering mechanism 4, and its front right part is connected to the middle part of the bottle feeding mechanism 2.

[0022] The nitrogen filling and stoppering mechanism 4 includes a nitrogen filling component, a stoppering component, and a nitrogen filling, stoppering, and bottle transfer component; the nitrogen filling component and the stoppering component are located at the upper left rear and upper right of the nitrogen filling, stoppering, and bottle transfer component, and the stoppering component is connected to the stoppering mechanism 1.

[0023] The nitrogen-filling, stoppering, and bottle-transferring component is a rotary bottle-transferring component.

[0024] The stopper-removing, nitrogen-filling, and bottle-pressing mechanism 8 includes a stopper-removing and pressing component, a nitrogen-filling component, and a nitrogen-filling and bottle-transferring component. The stopper-removing and pressing component and the nitrogen-filling component are located at the upper left and upper right of the nitrogen-filling and bottle-transferring component, respectively. The front right and rear right parts of the nitrogen-filling and bottle-transferring component are connected to the middle part of the bottle-feeding mechanism 2 and the front left part of the nitrogen-filling, stoppering, and bottle-transferring component.

[0025] The filling and nitrogen-filling bottle transfer component is a rotary bottle transfer component.

[0026] A bottle-turning transition mechanism 6 is also provided between the nitrogen-filling and stoppering bottle-transferring component of the nitrogen-filling and stoppering mechanism 4 and the filling and nitrogen-filling bottle-transferring component of the stoppering, nitrogen-filling, and stoppering mechanism 8.

[0027] The bottle transfer mechanism 6 is a rotary bottle transfer mechanism.

[0028] A bottle outlet mechanism 7 is also provided between the filling, filling and transferring bottle component of the nitrogen-filling and sealing mechanism 8 and the bottle delivery mechanism 2.

[0029] The bottle dispensing mechanism 7 is a rotary bottle dispensing mechanism.

[0030] A pre-nitrogen filling mechanism 5 is also provided between the nitrogen filling and stoppering mechanism 4 and the bottle delivery mechanism 2. The pre-nitrogen filling mechanism 5 includes a pre-nitrogen filling component and a pre-nitrogen filling bottle transfer component. The pre-nitrogen filling bottle transfer component is a rotary bottle transfer component, which is provided between the nitrogen filling and stoppering rotary bottle transfer component of the nitrogen filling and stoppering mechanism 4 and the bottle delivery mechanism 2. The pre-nitrogen filling component is provided on the upper part of the pre-nitrogen filling rotary bottle transfer component.

[0031] Compared with existing similar technologies and equipment, the rotary filling, nitrogen-filling, and stoppering device of this utility model has the following technical advantages:

[0032] First, the process is simple, eliminating the vacuuming step and optimizing mechanical operations; it also reduces the floor space occupied by the machinery; at the same time, it saves on the air conditioning purification area and reduces operating costs.

[0033] Secondly, the absence of a vacuuming process avoids the risk of drawing vapors from the liquid into the vacuum pipe during vacuuming, which would then condense and remain inside the pipe, potentially causing excessive particulate matter. When filling with nitrogen, these particulates might be blown back into the bottle, thus affecting the quality of the medicine.

[0034] Third, it integrates filling, nitrogen filling, and stoppering into one unit. It uses a jacketed tube for filling and nitrogen protection during filling to keep the liquid medicine isolated from the air at all times. After filling, it is immediately stoppered, which reduces the time that the liquid medicine is exposed to the air, thereby effectively improving the pass rate and quality of the medicine.

Detailed Implementation

[0037] The present invention will be further described below with reference to the accompanying drawings and embodiments. The following description is by way of example, but the scope of protection of the present invention should not be limited thereto.

[0038] The orientations described in this specification and in the accompanying drawings are as follows:

[0040] Example 1:

[0041] The rotary filling and nitrogen-filling stoppering device of this embodiment consists of a frame 9, a bottle feeding mechanism 2, a bottle separating mechanism 3, a nitrogen-filling and stoppering mechanism 4, a stopper sorting mechanism 1, and a stopper taking, nitrogen-filling, filling, and pressing mechanism 8. The bottle feeding mechanism 2 is arranged in a left-right direction on the front of the upper part of the frame 9, and the bottle separating mechanism 3 is arranged on the front right side of the bottle feeding mechanism 2.

[0042] The nitrogen-filling and stoppering mechanism 4 is located on the right rear side of the bottle feeding mechanism 2 on the frame 9, and the stoppering mechanism 1 is located on its right side. The nitrogen-filling and stoppering mechanism 4 consists of a nitrogen-filling component, a stoppering component, and a nitrogen-filling, stoppering, and bottle-transferring component. The nitrogen-filling, stoppering, and bottle-transferring component is a rotary bottle-transferring component (i.e., a rotary dial). The nitrogen-filling component and the stoppering component are located on the upper left rear and upper right sides of the nitrogen-filling, stoppering, and bottle-transferring component. The stoppering mechanism 1 is connected to the stoppering component and provides it with a stopper.

[0043] The stopper-taking, nitrogen-filling, and stoppering mechanism 8 is located on the upper left side of the frame 9. Its right side is connected to the nitrogen-filling and stoppering mechanism 4, and its front right side is connected to the middle of the bottle feeding mechanism 2. The stopper-taking, nitrogen-filling, and stoppering mechanism 8 consists of a stopper-taking and stoppering component, a nitrogen-filling component, and a nitrogen-filling and bottle-transferring component. The nitrogen-filling and bottle-transferring component is a rotary bottle-transferring component (i.e., a rotary dial). The stopper-taking and stoppering component and the nitrogen-filling component are located on the upper left and upper right sides of the nitrogen-filling and bottle-transferring component, respectively. The front right and rear right parts of the nitrogen-filling and bottle-transferring component are connected to the middle of the bottle feeding mechanism 2 and the front left part of the nitrogen-filling and stoppering component.

[0044] The bottle feeding mechanism 2, bottle separating mechanism 3, nitrogen filling and stoppering mechanism 4, stopper sorting mechanism 1, and stopper removal, nitrogen filling, and stoppering mechanism 8 (including the various components that make up these mechanisms, such as nitrogen filling component, stoppering component, nitrogen filling, stoppering and bottle moving component, stopper removal and stoppering component, filling and nitrogen filling component, and filling and nitrogen filling and bottle moving component, etc.) used in this embodiment are all commonly used existing components.

[0045] In use, firstly, clean medicine bottles (not shown in the attached diagram) are conveyed from the right end of the bottle feeding mechanism 2 to the left to the bottle separating mechanism 3. The separating screw of the bottle separating mechanism 3 separates the conveyed medicine bottles at equal distances. Then, they enter the nitrogen filling and bottle-moving mechanism 4, and are carried by the semi-circular groove on the periphery of the rotary dial of the nitrogen filling and bottle-moving component of the nitrogen filling and bottle-moving mechanism 4 to rotate clockwise. During its rotation, on the one hand, the nitrogen filling component at the top of the nitrogen filling and bottle-moving component will inject nitrogen gas into the medicine bottle (the time is usually controlled within 1-10 seconds, and the nitrogen pressure is 5KPa-50KPa). On the other hand, the stopper mechanism 1 will stopper the bottle. The nitrogen filling and sealing mechanism feeds nitrogen into the bottle. Once the bottle is filled with nitrogen, the nitrogen filling component moves away. Then, the sealing component, located above the nitrogen filling and sealing bottle transfer mechanism, quickly presses the stopper provided by the sealing mechanism 1 into the mouth of the medicine bottle. At this point, the medicine bottle is filled with nitrogen. The rotary dial of the nitrogen filling and sealing bottle transfer mechanism continues to rotate, carrying the nitrogen-filled medicine bottle, until it is transferred to the filling and sealing nitrogen filling and sealing mechanism 8. During this transfer, because the mouth of the medicine bottle is sealed with a stopper, the nitrogen inside the bottle will not escape. The nitrogen-filled medicine bottle is then transferred to the filling and sealing nitrogen filling and transferring mechanism. The rotary dial, with its semi-circular grooves, rotates. During this rotation, the stopper-removing and stopper-pressing component, located above the nitrogen-filling and transferring component, first removes the stopper from the nitrogen-filled medicine bottle. Then, the nitrogen-filling component, also located above the nitrogen-filling and transferring component, fills the already nitrogen-filled medicine bottle with the removed stopper. Simultaneously, nitrogen is introduced into the bottle to prevent outside air from entering due to its greater density. Furthermore, because the bottle was already filled with nitrogen, and nitrogen is continuously introduced during filling, the filled medicine... Since there is no opportunity for it to come into contact with air, the residual oxygen content in the filled liquid is extremely low. When the liquid in the bottle reaches the set dosage, the filling and nitrogen filling component is immediately removed. At the same time, the stopper removal and pressing component quickly moves the originally removed stopper downwards and presses it back into the mouth of the liquid bottle, completing the filling and sealing. At this time, nitrogen gas is still retained in the upper cavity of the bottle to protect the liquid. Afterwards, the liquid bottle after filling and sealing is carried and rotated by the rotary dial of the filling and nitrogen filling bottle transfer component until it reaches the middle of the bottle delivery mechanism 2. Then it is handed over to the bottle delivery mechanism 2 and transported to the left by the bottle delivery mechanism 2.

[0046] Example 2:

[0047] The rotary filling and nitrogen-filling stoppering device of this embodiment is an improvement of Embodiment 1. The difference between it and Embodiment 1 is that a pre-nitrogen filling mechanism 5 is also provided between the bottle feeding mechanism 2 and the nitrogen-filling stoppering mechanism 4. The pre-nitrogen filling mechanism 5 is composed of a pre-nitrogen filling component and a pre-nitrogen filling bottle transfer component. The pre-nitrogen filling bottle transfer component adopts a rotary bottle transfer component (i.e., a rotary dial), which is set between the nitrogen-filling stoppering rotary bottle transfer component of the nitrogen-filling stoppering mechanism 4 and the bottle feeding mechanism 2. The pre-nitrogen filling component is set on the upper part of the pre-nitrogen filling rotary bottle transfer component.

[0048] In use, firstly, clean medicine bottles (not shown in the attached diagram) are conveyed from the right end of the bottle feeding mechanism 2 to the left to the bottle separating mechanism 3. At this time, the separating screw of the bottle separating mechanism 3 separates the conveyed medicine bottles at equal distances. Then, they enter the pre-nitrogen filling mechanism 5, and are rotated by the semi-circular groove on the periphery of the rotary dial of the pre-nitrogen filling bottle transfer component of the pre-nitrogen filling mechanism 5. During its rotation, the pre-nitrogen filling component at the top of the pre-nitrogen filling rotating bottle transfer component injects nitrogen gas into the bottle (the time is usually controlled within 1-5 seconds, and the nitrogen pressure is 5KPa-50). After the nitrogen in the bottle is basically filled (kPa), the pre-filling nitrogen component is removed. At this time, the medicine bottle is filled with nitrogen, which can prevent air from being trapped in the subsequent process of being transported to the nitrogen filling and stoppering mechanism 4. Afterwards, the medicine bottle that has been pre-filled with nitrogen continues to be carried by the rotary dial of the pre-filling nitrogen bottle transfer component. When it is rotated to the rotary dial of the nitrogen filling and stoppering bottle transfer component, it is immediately transferred to the rotary dial of the nitrogen filling and stoppering bottle transfer component and carried by it. The subsequent nitrogen filling and stoppering steps are basically the same as in Example 1, and will not be described again here.

[0049] Example 3:

[0050] The rotary filling, nitrogen filling and stoppering device of this embodiment is an improvement of embodiment 2. The difference between it and embodiment 2 is that a bottle transfer mechanism 6 is also provided between the nitrogen filling and stoppering mechanism 4 and the stopper taking, nitrogen filling and pressing mechanism 8. The bottle transfer mechanism 6 adopts a rotary bottle moving component (i.e., a rotary dial).

[0051] During use, when the rotary dial of the nitrogen filling and stoppering bottle transfer component carries the medicine bottle filled with nitrogen and already stopped, it continues to rotate to the rotary dial of the bottle transfer mechanism 6. Then, the medicine bottle filled with nitrogen and already stopped is transferred to the rotary dial of the filling and nitrogen filling bottle transfer component of the stopper taking, nitrogen filling and stoppering mechanism 8, and is carried by it to rotate. The subsequent steps of stopper taking, nitrogen filling, filling and re-stopping are basically the same as in Example 2, and will not be described again here.

[0052] Example 4:

[0053] The rotary filling, nitrogen filling and stoppering device of this embodiment is an improvement of embodiment 3. The difference between it and embodiment 3 is that a bottle outlet mechanism 7 is also provided between the middle of the stopper taking, nitrogen filling and stoppering mechanism 8 and the bottle feeding mechanism 2. The bottle outlet mechanism 7 also adopts a rotary bottle moving component (i.e., a rotary dial).

[0054] During use, when the rotary dial of the filling, filling and sealing mechanism 8 carries the filled, nitrogen-filled and capped medicine bottle to the rotary dial of the bottle dispensing mechanism 7, the bottle is transferred to the rotary dial of the bottle dispensing mechanism 7 and rotated until it reaches the middle of the bottle feeding mechanism 2. Then, the bottle is transferred to the bottle feeding mechanism 2 and conveyed to the left.

[0055] This utility model's rotary filling and nitrogen-filling stopper device can be used for nitrogen-filling of high-value-added products such as glucose, antibiotics, amino acids, fat emulsions, oral liquids, nutrient solutions, and biological agents.
