Description

Technical Field

[0001] The present application relates to the technical field of pharmaceutical packaging production, and in particular to a double-cavity pre-filled product production line. Background Art

[0002] Most powder products on the market cannot be simply combined with standard syringes because they require a reconstitution step before administration. However, for home care and emergency use, people still hope to reduce the number of operation steps and the requirements for professional use. In response to this demand, the dual chamber system can provide a better option, which allows for on-site reconstitution and administration. The dual chamber container has two chambers: one chamber stores the powdered active ingredient, and the other chamber is filled with a matching diluent solution, separated by a rubber piston.

[0003] Since lyophilized dosage forms, three-in-one powders, and other powders account for a high proportion of approved biopharmaceutical products, dual-chamber systems are expected to show an upward trend and may become the preferred product in the emergency and home care markets.

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0038] In the description of the present invention, it should be understood that the terms "upper" and "lower" etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the position or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation of the present invention.

[0039] The purpose of this application is to provide a double-chamber pre-filled product production line to avoid the problem of low efficiency in double-chamber drug assembly.

[0040] It should be noted that in this embodiment, the X direction in the accompanying drawings is defined as the first direction, and the Y direction is defined as the second direction, and the first direction and the second direction are perpendicular to each other. To achieve the above purpose, the present invention provides the following technical solutions:

[0041] See also Figure 1 and Figure 2 This embodiment provides a double-chamber pre-filled product production line, including a nest box 100, a transfer conveyor line 200, a grabbing device 400, a powder filling device 500, a dissolving liquid filling device 600 and a sealing assembly 700.

[0042] The nest box 100 includes a nest plate and a dual-cavity container 110. Multiple dual-cavity containers 110 are placed on the nest plate. The dual-cavity container 110 includes a powder cavity 120 and a liquid cavity 130. The powder cavity 120 and the liquid cavity 130 are used to load powder and dissolving liquid respectively. The dual-cavity container 110 is provided with a bypass passage 111 for mixing powder and dissolving liquid.

[0043] It should be noted that the dual-chamber container 110 inside the nest box 100 in this example is of the wash-free and sterilization-free type. Other types of containers, such as containers that are washed and sterilized on the equipment or terminally sterilized, or other containers that are integrally packaged in the form of boxes, trays, plates, etc., or single containers that are pre-integrated, are also applicable to the production process provided in this embodiment. In addition, the specific shapes and structures of the nest box 100 and the nest plate used to place the dual-chamber container 110 can be adjusted according to actual needs as long as they can meet the above-mentioned purpose.

[0044] It can be understood that using a whole box of dual-cavity containers 110 as an operating unit can increase production speed and facilitate product quality control.

[0045] The transfer conveyor line 200 is used to drive the nest box 100 to move along the first direction. A grabbing station 210 is provided on the transfer conveyor line 200. A pallet moving station 300 is provided at one end of the grabbing station 210 along the second direction. The pallet moving station 300 is provided with a pallet moving device 310. The pallet moving device 310 is used to drive the nest plate and the double-cavity container 110 to move. The first direction and the second direction are perpendicular to each other.

[0046] It should be noted that the pallet moving device 310 set at the pallet moving station 300 is currently disclosed and belongs to the existing technology. You can refer to the material pallet moving device 310 described in Chinese patent CN202111645903.1 to move the nest plate and the injection container thereon to the specified position. This article will not go into details.

[0047] The gripping device 400 is located between the gripping station 210 and the tray moving station 300 . The gripping device 400 can drive the nest plate and the double-cavity container 110 to move.

[0048] It can be understood that the grabbing device 400 is used to grab the nest plate and the dual-cavity container 110, so that the nest plate and the dual-cavity container 110 before dosing can be transferred from the grabbing station 210 to the pallet moving station 300, and the nest plate and the dual-cavity container 110 after dosing can be transferred from the pallet moving station 300 to the grabbing station 210 to enter the subsequent process.

[0049] The powder packaging device 500 is disposed at one end of the tray moving station 300 along the first direction. The powder packaging device 500 is used to add powder into the powder chamber 120 .

[0050] The dissolving liquid filling device 600 is located on a side of the tray moving station 300 away from the grabbing station 210 . The dissolving liquid filling device 600 is used to add dissolving liquid to the double-chamber container 110 that has completed powder packaging.

[0051] The sealing assembly 700 includes a stopper hopper 710, a turning mechanism 720 and a stoppering station 730. The stoppering station 730 is used to add a stopper 711 to the double-chamber container 110 filled with powder and / or solvent. A filling station 610 is provided between the solvent filling device 600 and the stoppering station 730.

[0052] It can be understood that the powder filling device 500 and the dissolving liquid filling device 600 respectively fill the powder cavity 120 and the liquid cavity 130, and the stoppering station 730, the stopper hopper 710 and the turning mechanism 720 are shared by the two dosing systems. It should be noted that in this embodiment, the stoppers 711 added to the powder cavity 120 and the liquid cavity 130 are the same type of stoppers 711. If different types of stoppers 711 are required, it is only necessary to add the required sealing components 700.

[0053] Specifically, the double-chamber container 110 is provided with a powder chamber 120 and a liquid chamber 130. The tray moving device 310 drives the double-chamber container 110 to add powder to the powder chamber 120 in the powder filling device 500, and then the tray moving device 310 drives the double-chamber container 110 to the stoppering station 730 for the first stoppering, and then the double-chamber container 110 is moved to the filling station 610 to add the dissolving liquid through the dissolving liquid filling device 600, and then the double-chamber container 110 is moved to the stoppering station 730 again for the second stoppering, and then the gripping device 400 transfers the double-chamber container 110 to the nest box 100. At this point, the double-chamber container 110 completes the powder-liquid double stoppering after two dosings and two stoppers. Cavity pre-filled product, at this time, the powder cavity 120 and the liquid cavity 130 are separated by the rubber plug 711, and the powder and the dissolved liquid do not contact each other. When a powder-liquid dual-cavity pre-filled product is needed, it is only necessary to apply external force to move the rubber plug 711 between the powder cavity 120 and the liquid cavity 130 to the bypass passage 111, so that the dissolved liquid can flow into the powder cavity 120 where the powder is located, and then be mixed and used. In the entire production process, the powder and the dissolved liquid are filled in sequence from the same opening of the container, the opening direction and height of the container are consistent, the equipment structure is simple and compact, and it has strong versatility for different containers. Such a setting can improve the efficiency of dual-cavity drug assembly, thereby avoiding the problem of low efficiency of dual-cavity drug assembly.

[0054] It is understandable that since the method of filling powder and liquid from the same opening is adopted, the relevant equipment only needs to control the height difference between the outlet of the powder and liquid filling mechanism and the container opening, and the differences in material, shape, size, etc. of the dual-chamber container 110 can be ignored, which greatly improves the universal applicability of the relevant equipment.

[0055] Preferably, the powder filling device 500 includes a powder filling station, a powder bin 510, and a suction device 520. The powder filling station is used to place the double-chamber container 110, the powder bin 510 stores the powder, and the suction device 520 can be moved relative to the powder bin 510 and the powder filling station. The suction device 520 is used to transfer the powder to the double-chamber container 110.

[0056] It can be understood that the suction device 520 can quantitatively absorb the powder in the powder bin 510 according to the setting. After completing the powder absorption, the suction device 520 loads the powder into the double-chamber container 110 located at the powder loading station, completing the process of loading the powder into the powder chamber 120.

[0057] It should be noted that the powder packaging device 500 can use airflow packaging to specifically achieve the goal of preventing powder from adhering to the wall and not flying, so that after the rubber plug 711 is added to the powder chamber 120, it can be completely isolated from the dissolving liquid, and the problem of premature dissolution causing deterioration will not occur. The powder filling method can be adjusted according to actual needs as long as the above-mentioned purpose can be achieved.

[0058] Preferably, the filling station 610 includes a filling bracket and a filling needle, the filling needle is connected to the dissolving liquid filling device 600, and the filling needle is used to add the dissolving liquid to the dual-chamber container 110.

[0059] It is understandable that the filling needles located on the filling bracket are used to add the dissolving liquid to the dual-chamber container 110. In addition, the number and position of the filling needles located on the filling station 610 can be adjusted according to actual conditions as long as the above purpose can be achieved.

[0060] Preferably, the grabbing device 400 includes a telescopic shaft 410 and a grabbing arm 420. The grabbing arm 420 is rotatably connected to the telescopic shaft 410. The telescopic shaft 410 can drive the grabbing arm 420 to move along the extension direction of the double-chamber container 110. The grabbing arm 420 is provided with a vacuum suction cup, which is used to grab the nest plate.

[0061] The flexibly rotatable grabbing arm 420 grabs the nest plate through the vacuum suction cup, thereby moving the dual-cavity container 110 located on the nest plate, thereby preventing the dual-cavity container 110 from being contacted and contaminated before adding medicine.

[0062] Preferably, the stopper hopper 710 and the stoppering station 730 are respectively located at two ends of the turnover mechanism 720 in the first direction. A conveying path 712 is provided between the stopper hopper 710 and the turnover mechanism 720 , and the conveying path 712 is used to convey the stoppers 711 .

[0063] It can be understood that the plug 711 of the plug hopper 710 is transported to the flip mechanism 720 via the conveying path 712, and then the flip mechanism 720 rotates to move the plug 711 to the plugging station 730, and then the double-chamber container 110 filled with powder and / or dissolved liquid is plugged and sealed. The number of conveying paths 712 can be adjusted according to actual needs as long as the above purpose can be achieved.

[0064] Preferably, there are two powder packaging devices 500.

[0065] It can be understood that in this embodiment, there are two powder packaging devices 500, and the two powder packaging devices 500 can be used simultaneously to increase the efficiency of powder packaging. In addition, when one powder packaging device 500 fails, the other can be used immediately to avoid production interruption.

[0066] Preferably, the two powder packaging devices 500 are adjacently arranged along the second direction.

[0067] Such an arrangement can reasonably control the distance between each device, which is beneficial to simplifying the production process and increasing the production speed.

[0068] Preferably, the dissolving liquid filling device 600 includes a plurality of dissolving liquid filling pump groups 620 , and the plurality of dissolving liquid filling pump groups 620 are evenly arranged along the first direction.

[0069] It is understandable that the filling process of the dissolving liquid is completed by the dissolving liquid filling pump group 620 that controls the filling amount of the dissolving liquid and the dissolving liquid filling station 610 that performs the dissolving liquid filling action.

[0070] Preferably, the dissolving liquid filling pump group 620 adopts a ceramic plunger pump.

[0071] It should be noted that the dissolving liquid filling pump group 620 can also use a peristaltic pump, a stainless steel pump, a time pressure method, etc. to add the dissolving liquid, as long as the above-mentioned purpose can be achieved.

[0072] Preferably, the powder filling device 500 , the dissolving liquid filling device 600 and the sealing assembly 700 are arranged on the same side relative to the transfer conveying line 200 .

[0073] It can be understood that when the powder filling device 500, the dissolving liquid filling device 600 and the sealing assembly 700 are arranged on the same side of the transfer conveyor line 200, the production process can be optimized, the equipment structure can be simplified, and the versatility can be improved, making it better compatible with double-chamber container 110 products of different materials and specifications.

[0074] It should be noted that the specific positions of various devices, workstations, etc. in this embodiment can be adjusted according to actual needs as long as the above-mentioned purpose can be achieved.

[0075] In summary, the present invention provides a production line for dual-cavity pre-filled products. A transfer conveyor line 200 for nested boxes 100 moves in a first direction. Unpacked and opened nested boxes 100 are placed along the first direction and transported to a gripping station 210 via the transfer conveyor line 200. A gripping device 400 swings from its original position to the location of the nested boxes 100 and descends via a telescopic shaft 410. The vacuum suction cups on the gripping arms 420 grip the nesting plates in the nested boxes 100. The plates and the dual-cavity containers 110 thereon are then placed on a tray moving station 300 through a lifting and swinging motion. The empty nested boxes 100 remain on standby. The tray moving device 310 moves the dual-cavity containers 110 to a powder dispensing device 500 for powder dispensing. After dispensing is complete, the dual-cavity containers 110 are moved to a plugging station 730. A feeding station delivers a rubber plug 711 to a flipping mechanism 720, after which the powder cavities 120 are plugged. After the powder cavities 120 of all the double-cavity containers 110 are plugged, the double-cavity containers 110 are moved to the filling station 610. At this time, the solvent filling pump group 620 starts working, and the ceramic plunger pump is actuated to fill the solvent into the double-cavity container 110 on the nest plate. After filling, the liquid cavity 130 is plugged. The filling station 610 and the plugging station 730 are arranged adjacent to each other, which can shorten the exposure time of the liquid cavity 130. After the liquid cavity 130 is plugged, the nest plate is moved to the tray moving station 300, the grabbing device 400 sucks up the nest plate, and then places it into the empty nest box 100 waiting on the transfer conveyor line 200. After the filling and plugging is completed, the nest box 100 can be sent out of the equipment via the transfer conveyor line 200, and the entire filling and plugging production process of the powder-liquid dual-cavity pre-filled product is completed. With this arrangement, the production process is simple, the equipment structure is simple, and it is conducive to production environment control and stable production. It can improve the efficiency of dual-cavity drug assembly, thereby avoiding the problem of low efficiency of dual-cavity drug assembly.
