Description

Technical Field

[0001] The utility model relates to the technical field of medical packaging production equipment, and more specifically, to an infusion soft bag production line. Background Art

[0002] The infusion packaged in a non-PVC film soft bag has the characteristics of being non-toxic, having good environmental protection, low absorption of the injection solution, light weight, no additive dissolution, strong compatibility with the pharmaceutical industry, being able to automatically retract during infusion, not requiring air injection, good low-temperature resistance, and convenient transportation, etc., and has become the development trend of the international infusion industry.

[0003] The currently widely used non-PVC film full-automatic soft bag making and sealing production line in the market generally includes a bag making section and a sealing section; the main function of the bag making section is to produce empty bags by processes such as peripheral welding and blanking of non-PVC film materials and plastic interfaces; the main function of the sealing section is to fill and seal the qualified empty bags made in the bag making section, and finally produce finished bags.

[0004] The number of bags that can be operated simultaneously in the bag making section and the sealing section is the same, that is, the number of bags made in each cycle action of the bag making section is the same as the number of bags sealed in each cycle operation of the sealing section.

[0005] However, the existing non-PVC film full-automatic soft bag making and sealing production line has the following deficiencies:

[0006] The cycle time of each process in the bag making section is shorter than the cycle time of each process in the sealing section. Especially for the cycle time of the filling process, when producing products with a volume specification of 500 ml or more, the time of the filling process is much longer than the cycle time of the bag making section. Similarly, for products with a volume specification of less than 500 ml, the time of the sealing process is also longer than the cycle time of the bag making section; this will cause the following problems:

[0007] On the one hand, the made empty bags stay in the forming and bag making molds for a long time, and the film materials are affected by high temperature and the double-layer films are bonded together, resulting in filling overflow and defective bags.

[0008] On the other hand, due to the prolonged cycle time of the filling process, the cycle time of the entire automatic production line is correspondingly lengthened, and the production capacity of the production line cannot be fully utilized, resulting in the occupation and waste of resources.

[0009] In summary, how to provide an infusion soft bag production line that can reduce the rejection rate and fully utilize the production capacity of the production line is an urgent problem to be solved by those skilled in the art at present. Summary of the Utility Model

That is, one cycle of the filling section can consume the infusion soft bags produced by X cycles of the bag-making section. Even if the production speeds of the filling section and the bag-making section are the same, the waiting time of the infusion soft bags in the forming mold is reduced, the scrap rate of the infusion soft bags is reduced, and the production efficiency of the entire production line is improved.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0041] The core of the present invention is to provide an infusion soft bag production line, which improves the workpiece processing volume of a single cycle in the potting section by increasing the workstations of each process in the potting section, so that the production speed of the potting section is close to that of the bag-making section, thereby reducing the waiting time of empty bags in the forming die, and releasing the production capacity and speed of the production line, and improving production efficiency.

[0042] Please refer to Figures 1 - 4, a soft infusion bag production line, comprising:

[0043] The bag making section 1 comprises a first circulating conveyor belt 13 for transferring workpieces, and a forming process 11 and a welding process 12 arranged in sequence along the feeding direction of the first circulating conveyor belt 13; N groups of workstations are respectively arranged in the forming process 11 and the welding process 12;

[0044] The filling and sealing section 2 includes a second circulating conveyor belt 23 for workpiece transmission, and a filling process 21 and a sealing process 22 arranged in sequence along the feeding direction of the second circulating conveyor belt 23; the filling process 21 and the sealing process 22 are respectively provided with M groups of workstations, M = X * N, X is a natural number, and X ≥ 2;

[0045] The soft bag transfer and handover mechanism 3 is used to transfer the workpieces in the first circulating conveyor belt 13 to the second circulating conveyor belt 23 . M groups of workstations are arranged in the soft bag transfer and handover mechanism 3 .

[0046] In the actual production of infusion soft bags, there are mainly two processes: bag making and filling. Among them, bag making has a relatively fixed process, and its own specifications and sizes have little impact on the working hours. During filling, the outer cover and the soft bag interface need to be hot-melted during the capping process, and welding and stabilization welding are required after hot melting. The required working hours are much longer than the bag making working hours. In addition, during filling, the working hours required for soft bags of different specifications and sizes are also different. The working hours required for filling large-capacity soft bags are significantly longer than those for small-capacity soft bags. Therefore, there is a huge difference between filling and bag making. There is a large difference in working hours. Therefore, the number of workstations in each process in the filling section 2 is increased, and this number is a multiple of the number of workstations in each process in the bag-making section 1. For example, the multiple is X, so that the filling section 2 is executed once, and the soft bags produced by the bag-making section 1 executed X times can be consumed, thereby making the overall production speed of the filling section 2 consistent with the overall production speed of the bag-making section 1, reducing the downtime waiting time of the bag-making section 1, and reducing the residence time of the infusion soft bag in the forming process 11, thereby reducing the defective rate of the infusion soft bag.

[0047] The value of X is related to the working hours of each process in bag making section 1 and filling section 2. Taking the production of 500ml finished bags as an example, the working hours of filling process 21 are close to sealing process 22, which is about 5s, and the working hours of welding process 12 and forming process 11 are about 2.5s. Therefore, the value of X is the maximum working hours in filling section 2 divided by the maximum working hours in bag making section 1, and rounded. For example, X=2 here, the production speed of bag making section 1 and filling section 2 can be kept consistent, which can release the production line capacity, improve production efficiency, and reduce defective products.

[0048] When the specifications of the infusion soft bag increase, the working hours of the filling process 21 increase, while the working hours of the other processes remain basically unchanged, that is, the maximum working time in the filling section 2 becomes longer, while the maximum working time in the bag making section 1 remains unchanged, and the value of X increases, and its value set is {3, 4, 5...} to meet the consistent production speed of the bag making section 1 and the filling section 2.

[0049] In some embodiments, Figure 3 As shown, a plurality of groups of bag making fixtures 14 are arranged in the first circulating conveyor belt 13, and the bag making fixtures 14 are arranged at equal intervals;

[0050] With this arrangement, the spacing between the bag-making clamps 14 is fixed, which facilitates the installation and fixation of the bag-making clamps 14 and the first circulating conveyor belt 13, and the single feed amount of the first circulating conveyor belt 13 can be one station interval or N station intervals, wherein N is the number of stations in the forming process 11 or the welding process 12, and the overall flexibility is relatively high. The single feed amount of N station intervals is the normal working feed amount of the bag-making section 1, while the single feed amount of one station interval is mainly used for equipment debugging.

[0051] Correspondingly, a plurality of groups of potting fixtures 25 are arranged in the second circulating conveyor belt 23, and the potting fixtures 25 are arranged at equal intervals, and the arrangement interval of the potting fixtures 25 is equal to the arrangement interval of the bag making fixtures 14;

[0052] When the spacing of the filling and sealing clamps 25 in the second circulating conveyor belt 23 is equal to the spacing of the bag making clamps 14 in the first circulating conveyor belt 13, the soft bag transfer and handover mechanism 3 does not need to adjust the spacing of the infusion soft bags when transferring the infusion soft bags from the first circulating conveyor belt 13 to the second circulating conveyor belt 23. N infusion soft bags can be transferred synchronously, which improves the transfer efficiency and facilitates the control of the action speed of the soft bag transfer and handover mechanism 3, so that its working hours are consistent with those of the bag making section 1 and the filling and sealing section 2, thereby improving the production efficiency of the entire production line;

[0053] like Figure 2 As shown, the arrangement spacing of the bag making fixture 14 is the same as the arrangement spacing of the filling fixture 25, and adopts the design of N=3, X=2, M=6, that is, the single feeding amount of the first circulating conveyor belt 13 is three station intervals, and the single feeding amount of the second circulating conveyor belt 23 is six station intervals.

[0054] In other embodiments, such as Figure 4 As shown, a plurality of groups of potting fixtures 25 are arranged in the second circulating conveyor belt 23, M groups of potting fixtures 25 constitute a potting circulation group, the arrangement spacing of the potting fixtures 25 in the same potting circulation group is equal to the arrangement spacing of the bag making fixtures 14, and the potting circulation groups are arranged at equal intervals;

[0055] Regarding the encapsulation fixtures 25 included in one cycle in the encapsulation section 2 as an encapsulation cycle group, the layout spacing of the encapsulation cycle group may not be equal to the layout spacing of the bag-making fixtures 14, so as to have an obvious demarcation line between different encapsulation cycle groups, reducing the influence between the workpieces in the processing state and the workpieces in the non-processing state. This influence is mainly the influence in aspects such as thermal radiation;

[0056] The feeding amount of the second circulation conveyor belt 23 each time is the interval amount of one encapsulation cycle group, such as Figure 1 As shown, with N = 2, X = 2, M = 4, that is, four groups of encapsulation fixtures 25 are arranged in the encapsulation cycle group. The single feeding amount of the first circulation conveyor belt 13 is the interval of two workstations, and the single feeding amount of the second circulation conveyor belt 23 is the interval of one encapsulation cycle group.

[0057] In some other embodiments, several groups of bag-making fixtures 14 are arranged in the first circulation conveyor belt 13. N groups of bag-making fixtures 14 form a bag-making cycle group. The bag-making fixtures 14 within the same bag-making cycle group are arranged at equal intervals, and the bag-making cycle groups are arranged at equal intervals;

[0058] The single feeding amount of the first circulation conveyor belt 13 is the layout interval of one bag-making cycle group. The layout spacing of the bag-making cycle group can also be unequal to the layout spacing of the bag-making fixtures 14. The purpose is also to reduce the influence between the workpieces in the processing state and the workpieces in the non-processing state.

[0059] Correspondingly, several groups of encapsulation fixtures 25 are arranged in the second circulation conveyor belt 23. N groups of encapsulation fixtures 25 form a sub-encapsulation cycle group, and X groups of sub-encapsulation cycle groups form an encapsulation cycle group;

[0060] The layout spacing of the encapsulation fixtures 25 within the same sub-encapsulation cycle group is equal to the layout spacing of the bag-making fixtures 14 within the same bag-making cycle group. The layout spacing of the sub-encapsulation cycle groups within the same encapsulation cycle group is the same as the layout spacing of the bag-making cycle group, and the encapsulation cycle groups are arranged at equal intervals;

[0061] Taking N = 2, X = 2, M = 4 as an example, one bag-making cycle group contains two bag-making fixtures 14, one sub-encapsulation cycle group includes two encapsulation fixtures 25, and one encapsulation cycle group includes two sub-encapsulation cycle groups, that is, one encapsulation cycle group includes four encapsulation fixtures 25. The single feeding amount of the first circulation conveyor belt 13 is the interval of one bag-making cycle group, while the single feeding amount of the second circulation conveyor belt 23 is the interval of two bag-making cycle groups. An obvious demarcation line will appear every two workstation intervals, which helps to separate the workpieces in the processing state from the workpieces in the non-processing state, so that the workpieces in the non-processing state reduce the amount of thermal radiation absorbed from the processing workstations.

[0062] In addition, both the first circulating conveyor belt 13 and the second circulating conveyor belt 23 adopt annular conveyor belts and are driven by servo motors to ensure high motion control accuracy.

[0063] As Figure 1 and Figure 2 shown, the bag-making section 1 further includes:

[0064] A film feeding mechanism 7, a printing mechanism 8, and a film pulling mechanism 9 that are arranged in sequence upstream of the forming process 11;

[0065] An automatic upper interface mechanism 5 for automatically feeding the interfaces of soft bags, and is arranged in parallel with the welding process 12;

[0066] The film feeding mechanism 7 is mainly used for transporting the raw materials of infusion soft bags, the printing mechanism 8 is mainly used for printing relevant text labels or information on the outer wall of the infusion soft bags, the film pulling mechanism 9 is mainly used for the flat traction of the film raw materials, and the automatic upper interface mechanism 5 is mainly used for feeding the soft bag interfaces, so that they are welded into one body with the soft bags produced by the forming process 11 at the welding process 12. The film feeding mechanism 7, the printing mechanism 8, the film pulling mechanism 9, and the automatic upper interface mechanism 5 are all prior arts and will not be elaborated here.

[0067] The filling and sealing section 2 further includes:

[0068] A finished product bag conveying mechanism 6 for conveying the finished product bags, and is arranged in the downstream section of the sealing process 22;

[0069] A finished product bag pushing mechanism 24 for transferring the finished product bags into the finished product bag conveying mechanism 6, and is arranged downstream of the sealing process 22, or is arranged in parallel with the sealing process 22;

[0070] An automatic lid supplying mechanism 4 for automatically feeding the outer lids of the soft bags, and is arranged in parallel with the sealing process 22;

[0071] The finished product bag conveying mechanism 6 is mainly used to transport the filled finished product bags away from the production line. It mainly relies on the finished product bag pushing mechanism 24 to peel the infusion soft bags with the outer lids welded from the filling and sealing fixture 25 and naturally drop them onto the conveyor belt of the finished product bag conveying mechanism 6. The automatic lid supplying mechanism 4 is mainly used for automatically feeding the outer lids, so that the outer lids are sealed with the filled infusion soft bags in the sealing process 22. Among them, the finished product bag conveying mechanism 6, the finished product bag pushing mechanism 24, and the automatic lid supplying mechanism 4 are all prior arts and will not be elaborated here.

[0072] Among them, both the bag-making fixture 14 and the filling and sealing fixture 25 are combined fixtures, including a connecting plate and a bag clamp. The connecting plate is used for connecting the bag clamp and the conveyor belt. The bag clamp is a fixture with a driving opening positioning groove, and they are all prior arts and will not be elaborated here.

[0073] In some embodiments, such as Figure 1As shown in the figure, the first circulating conveyor belt 13 and the second circulating conveyor belt 23 are arranged in parallel and partially overlapped, and the soft bag transfer and handover mechanism 3 is arranged at the overlapping position of the first circulating conveyor belt 13 and the second circulating conveyor belt 23;

[0074] Limited by the production site, the bag-making section 1 and the filling and sealing section 2 can be partially overlapped to save floor space. At this time, the soft bag transfer and handover mechanism 3 can adopt a flipping mechanism to realize the transfer of the infusion soft bag from the bag-making section 1 to the filling and sealing section 2. The soft bag transfer and handover mechanism 3 and its flipping mechanism are both prior arts and will not be elaborated here.

[0075] In some other embodiments, such as Figure 2 As shown in the figure, the first circulating conveyor belt 13 and the second circulating conveyor belt 23 are arranged in a straight line, and the soft bag transfer and handover mechanism 3 partially overlaps with the first circulating conveyor belt 13 and the second circulating conveyor belt 23 respectively;

[0076] For some production lines not limited by the site, a straight-line arrangement can be adopted, and the soft bag transfer and handover mechanism 3 adopts a linear slide rail design, that is, the infusion soft bag is obtained at the overlapping position with the first circulating conveyor belt 13, and the infusion soft bag is released at the overlapping position with the second circulating conveyor belt 23, so as to realize the transfer of the infusion soft bag from the bag-making section 1 to the filling and sealing section 2. The soft bag transfer and handover mechanism 3 and its linear slide rail design are both prior arts and will not be elaborated here.

[0077] Such as Figure 1 As shown in the figure, the welding process 12 includes a first hot welding process 121, a second hot welding process 122 and a cold welding process 123 arranged in sequence, and N groups of workstations are respectively arranged in the first hot welding process 121, the second hot welding process 122 and the cold welding process 123;

[0078] In the bag-making section 1, the working hours of the welding process 12 are longer than those of the forming process 11, resulting in a large difference in the working hours of adjacent processes, which is not conducive to improving the production efficiency of the bag-making section 1. Therefore, the welding process 12 is divided into three processes, namely the first hot welding process 121, the second hot welding process 122 and the cold welding process 123. Moreover, the first hot welding process 121 and the second hot welding process 122 are mainly used for material preheating and hot melt connection. Therefore, the welding temperature of the first hot welding process 121 is higher than that of the second hot welding process 122, while the cold welding process 123 is mainly used for the cooling and forming of the welding position, and the welding temperature is normal temperature. Dividing the welding process 12 into three independent processes helps to extend the welding and holding time of each infusion soft bag, ensure the welding quality, and make the working hours of each individual process consistent with those of the forming process 11, thereby improving the production efficiency of the bag-making section 1.

[0079] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the various embodiments, reference can be made to each other.

[0080] The above has introduced the infusion soft bag production line provided by the present utility model in detail. Specific examples are used herein to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
