Abstract
Description
Technical Field
[0001] This utility model relates to food and pharmaceutical production equipment, and more particularly to a soft bag filling and sealing device. Background Technology
[0002] Existing infusion bag production lines typically involve continuous bag making, filling, and sealing in a sterile environment. However, for non-terminally sterilized soft bag products (i.e., soft bags are not sterilized after packaging), the soft bags need to be placed inside outer packaging bags after bag making. Therefore, during filling, the outer packaging bag must be removed first, then the soft bag filled with the medication, and finally sealed. Maintaining a sterile environment during filling and sealing to prevent contamination of the medication is crucial during production. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a soft bag filling and sealing device with a simple and reasonable structure that helps reduce the risk of pollution.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A soft bag filling and sealing device includes an isolator. The isolator contains, in sequence, an outer packaging bag sterilization area, an outer packaging bag unpacking area, a soft bag feeding area, a separator, and a filling and sealing area. The soft bag feeding area has a first clamping conveyor line, and the filling and sealing area has a second clamping conveyor line. A soft bag transfer mechanism is provided between the first and second clamping conveyor lines. The separator has a channel for the soft bag transfer mechanism to pass through. The first and second clamping conveyor lines are arranged in a ring and have multiple soft bag positioning clamps evenly distributed circumferentially. The soft bag transfer mechanism includes a swing arm and an arc-shaped transfer component located at the swing end of the swing arm. Multiple soft bag positioning clamps are evenly distributed around the swing center of the swing arm on the arc-shaped transfer component. The swing center of the swing arm is located in the soft bag feeding area.
[0006] As a further improvement to the above technical solution: the second clamping conveyor line is provided with a first weighing station, a filling station, a second weighing station, a plugging station and a heat sealing station in sequence along the conveying direction.
[0007] As a further improvement to the above technical solution, a detection and rejection station is also provided downstream of the heat sealing station.
[0008] As a further improvement to the above technical solution: a nitrogen filling station is provided between the first weighing station and the filling station.
[0009] As a further improvement to the above technical solution: a temporary storage area for unpacking is provided between the sterilization area of the outer packaging bag and the area for unpacking the outer packaging bag.
[0010] As a further improvement to the above technical solution: an upper bag temporary storage area is provided upstream of the sterilization area of the outer packaging bag.
[0011] As a further improvement to the above technical solution: the upper bag storage area, the outer packaging bag sterilization area and the outer packaging bag unpacking area are provided with a first soft bag conveyor line.
[0012] As a further improvement to the above technical solution: the outer packaging bag removal area and the soft bag feeding area are connected by a second soft bag conveyor line, and the soft bag feeding area is equipped with a feeding robot for feeding soft bags from the second soft bag conveyor line to the first clamping conveyor line.
[0013] As a further improvement to the above technical solution: there are two or more feeding robots, and the two or more feeding robots are distributed at intervals along the conveying direction of the second soft bag conveying line.
[0014] Compared with the prior art, the advantages of this utility model are:
[0015] The flexible bag filling and sealing equipment disclosed in this utility model involves the following steps: In operation, the flexible bag, along with its outer packaging bag, is first fed into the outer packaging bag sterilization area for sterilization to prevent contamination of the downstream outer packaging bag removal area, flexible bag feeding area, and filling and sealing area. After the flexible bag and its outer packaging bag are transferred to the outer packaging bag removal area, the outer packaging bag is removed, and the flexible bag continues to be transferred to the flexible bag feeding area. A first clamping conveyor line clamps the opening tube of the flexible bag and transports it to a flexible bag transfer mechanism. The flexible bag transfer mechanism receives the flexible bag from the first clamping conveyor line and transfers it through a separator to the filling and sealing area. A second clamping conveyor line clamps the flexible bag transfer mechanism. The structure conveys the soft bags through its opening tube, and drives the soft bags to complete filling and sealing processes. Because a separator is further set between the soft bag feeding area and the filling and sealing area, it helps to ensure a high cleanliness level in the filling and sealing area, thereby reducing the risk of contamination. The overall structure is simple and reasonable. The swing-type soft bag transfer mechanism facilitates the transfer of soft bags with the first clamping conveyor line and the second clamping conveyor line arranged in a ring, and requires little space. Correspondingly, the channel size on the separator is small, which helps to improve the separation effect between the soft bag feeding area and the filling and sealing area. Furthermore, the swing center of the swing arm is set in the soft bag feeding area, which helps to ensure a clean environment in the filling and sealing area.
[0016] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0025] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0027] Figures 1 to 3 This illustration shows an embodiment of the flexible bag filling and sealing equipment of this utility model. The flexible bag filling and sealing equipment of this embodiment includes an isolator 1, within which are sequentially arranged an outer packaging bag sterilization area 2, an outer packaging bag unpacking area 3, a flexible bag feeding area 4, a separator 5 (e.g., a partition), and a filling and sealing area 6. The flexible bag feeding area 4 is equipped with a first clamping conveyor line 41, and the filling and sealing area 6 is equipped with a second clamping conveyor line 61. A flexible bag transfer mechanism 7 is provided between the first clamping conveyor line 41 and the second clamping conveyor line 61. The separator 5 has a channel for the flexible bag transfer mechanism 7 to pass through. Preferably, the outer packaging bag sterilization area 2 uses VHP sterilization (i.e., using high-concentration hydrogen peroxide vapor to rapidly kill microorganisms), resulting in good sterilization effect.
[0028] In this embodiment of the soft bag filling and sealing equipment, during use, the soft bag 100, together with the outer packaging bag 400, is first fed to the outer packaging bag sterilization area 2 for sterilization to prevent contamination of the outer packaging bag removal area 3, the soft bag feeding area 4, and the filling and sealing area 6 located downstream. After the soft bag 100, together with the outer packaging bag 400, is transferred to the outer packaging bag removal area 3, the outer packaging bag 400 is removed, and the soft bag 100 continues to be transferred to the soft bag feeding area 4. The first clamping conveyor line 41 clamps the mouth tube of the soft bag 100 and conveys the soft bag 100 to the filling and sealing area 6. The soft bag transfer mechanism 7 receives soft bags 100 from the first clamping conveyor line 41 and transfers them through the separator 5 to the filling and sealing area 6. The second clamping conveyor line 61 clamps the opening of the soft bag 100 from the soft bag transfer mechanism 7 and drives the soft bag 100 to complete the filling and sealing processes. Since the soft bag feeding area 4 and the filling and sealing area 6 are further separated by the separator 5, it helps to ensure the high cleanliness level of the filling and sealing area 6, thereby reducing the risk of contamination. The overall structure is simple and reasonable. Preferably, the feeding of the soft bag 100 along with the outer packaging bag 400 and the removal of the packaging bag 400 can be completed by the operator using the operating gloves on the isolator 1. Manual operation helps to reduce equipment costs and is far from the filling and sealing area 6, so it will not cause contamination to the filling and sealing area 6. Furthermore, the first clamping conveyor line 41 and the second clamping conveyor line 61 are arranged in a ring and a plurality of soft bag positioning clamps 8 are evenly provided along the circumference, which can realize the recycling of the soft bag positioning clamps 8 and occupy less space in the isolator 1. The soft bag transfer mechanism 7 includes a swing arm 71 and an arc-shaped transfer component 72 located at the swing end of the swing arm 71. A plurality of soft bag positioning clamps 8 are evenly provided on the arc-shaped transfer component 72 around the swing center of the swing arm 71. The swing center of the swing arm 71 is located in the soft bag feeding area 4. When the soft bags 100 are conveyed one by one to the left end of the first clamping conveyor line 41, the soft bags 100 are transferred to the soft bag positioning clamps 8 on the arc-shaped transfer member 72. The swing arm 71 drives the arc-shaped transfer member 72 to rotate counterclockwise, so that each soft bag positioning clamp 8 on the arc-shaped transfer member 72 clamps one soft bag 100. Then the soft bags 100 are transferred one by one to the soft bag positioning clamps 8 on the second clamping conveyor line 61. The second clamping conveyor line 61 drives the soft bags 100 to continue to be conveyed to the right.
[0029] The swing-type soft bag transfer mechanism 7 facilitates the transfer of soft bags 100 with the first clamping conveyor line 41 and the second clamping conveyor line 61 arranged in a ring, and requires little space. Correspondingly, the channel size on the separator 5 is small, which helps to improve the separation effect between the soft bag feeding area 4 and the filling and sealing area 6. Furthermore, the swing center of the swing arm 71 is located in the soft bag feeding area 4, which helps to ensure a clean environment in the filling and sealing area 6 (friction exists at the swing center when the swing arm 71 moves, which may generate particles).
[0030] See details Figure 1In a preferred embodiment, the second clamping conveyor line 61 is provided with a first weighing station 62, a filling station 63, a second weighing station 64, a stoppering station 65, and a heat sealing station 66 in sequence along the conveying direction. When the soft bag 100 passes through the first weighing station 62, it is weighed before filling. When it passes through the filling station 63, it is filled with the medicine liquid 200. When it passes through the second weighing station 64, it is weighed after filling (this can be sampling weighing, partial weighing, or full weighing) to calibrate the filling accuracy. When it passes through the stoppering station 65, the sealing plug 300 is pressed into the opening tube of the soft bag 100. Finally, when it passes through the heat sealing station 66, the sealing plug 300 is welded and sealed.
[0031] Furthermore, in this embodiment, a rejection inspection station 67 is provided downstream of the heat sealing station 66. The rejection inspection station 67 can inspect whether the filling, capping, heat sealing and other processes of the soft bag 100 are qualified. For qualified good products 101, they are discharged to the next process, and for defective products 102, they are rejected and recycled.
[0032] Furthermore, in this embodiment, a nitrogen-filling station 68 is provided between the first weighing station 62 and the filling station 63. Before the soft bag 100 is filled with the medicine liquid 200, nitrogen is filled at the nitrogen-filling station 68 to expel the air inside the soft bag 100, which helps to control the residual oxygen level inside the soft bag 100 and extend the shelf life of the medicine liquid 200.
[0033] Furthermore, in this embodiment, a temporary storage area 21 for unpacking is provided between the outer packaging bag sterilization area 2 and the outer packaging bag unpacking area 3. After the outer packaging bag 400 is sterilized in the outer packaging bag sterilization area 2, it can be temporarily stored in the temporary storage area 21. The operator can retrieve the temporarily stored outer packaging bag 400 for unpacking according to the speed of the back-end equipment. The structure is simple and reasonable.
[0034] Furthermore, in this embodiment, an upper bag storage area 22 is provided upstream of the outer packaging bag sterilization area 2. The operator feeds the soft bag 100 together with the outer packaging bag 400 to the upper bag storage area 22 for temporary storage until the feeding is completed, and then gradually conveys it to the outer packaging bag sterilization area 2 for sterilization. The structure is simple and the layout is reasonable.
[0035] In a preferred embodiment, the upper bag storage area 22, the outer packaging bag sterilization area 2, and the outer packaging bag removal area 3 are provided with a first soft bag conveyor line 23 (e.g., a conveyor mesh belt) to facilitate the transfer of the outer packaging bag 400 between the upper bag storage area 22, the outer packaging bag sterilization area 2, and the outer packaging bag removal area 3.
[0036] Furthermore, in this embodiment, the outer packaging bag removal area 3 and the soft bag loading area 4 are connected by a second soft bag conveyor line 9 (e.g., a conveyor belt). The soft bag loading area 4 is equipped with a loading robot 42 for loading soft bags 100 from the second soft bag conveyor line 9 onto the first clamping conveyor line 41. After the outer packaging bag 400 is manually removed, the soft bag 100 is taken out and loaded onto the second soft bag conveyor line 9. When the soft bag 100 is conveyed to the loading robot 42, the loading robot 42 grabs the soft bag 100 and loads it onto the soft bag positioning fixture 8 of the first clamping conveyor line 41. The structure is reasonable and the loading efficiency is high.
[0037] In a preferred embodiment, there are two or more feeding robots 42, which are spaced apart along the conveying direction of the second soft bag conveyor line 9. Having two or more feeding robots 42 helps to further improve the efficiency of feeding the soft bags 100 to the soft bag positioning fixture 8 of the first clamping conveyor line 41, ensuring that the production cycle time of each process in the equipment remains consistent.
[0038] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it 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 content of the present invention, should fall within the protection scope of the present invention.
