Description

Technical Field

[0001] This application relates to the field of pharmaceutical equipment technology, specifically to a high-speed soft bag large-volume infusion production line. Background Technology

[0002] The existing soft bag large-volume parenteral solution production line can be found in the technical solution disclosed in publication number CN101417712A, such as... Figure 28 As shown: The soft bag large-volume parenteral solution production line includes a bag-making section, a filling section, a frame 13, and a control system 19; it also includes a bag transfer mechanism 8 located between the bag-making section and the filling section; the bag-making section and the filling section are arranged in parallel and staggered, and the center lines of the bag-out mechanism 7 and the bag-in mechanism 9 coincide; the bag-making section mainly consists of a film feeding mechanism 1, a printing mechanism 2, a film pulling mechanism 3, a forming mechanism 4, an interface welding mechanism 5, an interface cooling mechanism 6, a bag-out mechanism 7, an automatic interface feeding mechanism 16, an interface conveying mechanism 17, and an interface preheating mechanism 18, etc.; the filling section mainly consists of a bag-in mechanism 9, a filling mechanism 10, a cap welding mechanism 11, a bag unloading mechanism 12, a bag conveying mechanism 14, and an automatic cap feeding mechanism 15, etc. Its working process is as follows: the film feeding mechanism 1 and the film pulling mechanism 3 feed the film 2111 into the printing mechanism 2 and the forming mechanism 4. The printing mechanism prints information such as production batch number, production date, and product registration information onto the membrane 2111. The forming mechanism 4 processes the interface 2112, which is fed by the automatic interface feeding mechanism 16 and the interface conveying mechanism 17 and heated by the interface preheating mechanism 18, into a bag 211. The bag 211 is fed into the bag transfer mechanism 8 through the interface welding mechanism 5, the interface cooling mechanism 6 and the bag exit mechanism 7. The bag transfer mechanism 8 flips the bag 211 90 degrees and then sends it into the bag inlet mechanism 9. The bag conveying mechanism 14 sends the bag 211 sequentially into the filling mechanism 10 (where the medicine is filled) and the cap welding mechanism 11 (where the cap 212 sent by the automatic cap feeding mechanism 15 is welded to the bag 211). The bag unloading mechanism 12 takes the soft bag large-volume infusion 21 out of the bag conveying mechanism 14, completing the production of the soft bag large-volume infusion 21.

[0003] In actual production, it was found that the filling section took approximately 1.2 to 1.4 times longer than the bag-making section. Figure 28 As can be seen, the bag-making section and the filling section produce the same number of bags at a time, namely 6. Therefore, the production speed of the filling section is the same as the speed of the entire production line. This means that after the bag-making section finishes making bags, it must wait for the filling section to finish filling before it can start making bags again. This results in the bag-making section's production capacity not being fully utilized. To address this issue, this application proposes a high-speed soft bag large-volume infusion production line. Utility Model Content

[0004] The purpose of the present application is: to solve the problem that the filling section takes about 1.2-1.4 times of the bag making section in the actual production process of the prior art, from Figure 28 It can be seen that the bag making section and the filling section complete one bag at a time, i.e. 6, so the production speed of the filling section is the speed of the whole production line, i.e. after the bag making section completes bag making, it needs to wait for the filling section to complete filling before it can make bags again, which leads to the technical problem that the production capacity of the bag making section is not fully utilized, and the present application provides a high-speed soft bag large infusion production line.

[0005] In order to achieve the above purpose, the present application specifically adopts the following technical scheme:

[0006] A high-speed soft bag large infusion production line, comprising a rack, an upper bag making section, a bag transfer mechanism, a filling section, and a control system, characterized in that the number of working units in each mechanism in the filling section is 1.5 times the number of working units in each mechanism in the bag making section.

[0007] A bag storage mechanism is additionally provided, the number of working units on the bag storage mechanism is greater than or equal to twice the number of working units in each mechanism in the bag making section, and the bag storage mechanism can send a number of bags equal to the number of working units in each mechanism in the filling section to the bag transfer mechanism.

[0008] Further, the bag storage mechanism comprises a fixed frame provided on the rack, the fixed frame is provided with a driving synchronous wheel and a driven synchronous wheel, the two are connected through a synchronous belt transmission, and is provided with a servo drive unit for driving the driving synchronous wheel to rotate, the fixed frame is provided with a guide rail, the guide rail is slidably connected with a plurality of positioning sliding blocks, and the plurality of positioning sliding blocks are connected with the synchronous belt, and the positioning sliding blocks are provided with bag clamps.

[0009] Further, the bag storage mechanism comprises a fixed frame provided on the rack, the fixed frame is provided with a linear actuator, and is provided with a servo drive unit for driving the linear actuator to act, the fixed frame is slidably connected with a connecting piece, and the connecting piece is connected with the output end of the linear actuator, and the connecting piece is linearly provided with a plurality of bag clamps.

[0010] Further, the bag transfer mechanism has a turnover beam, and the fixed frame is mounted on the turnover beam.

[0011] The beneficial effects of this application are as follows: This application solves the problem of inconsistent processing times between the bag making and filling sections by increasing the number of bags processed in each mechanism of the filling section to 1.5 times the number of bags processed in each mechanism of the bag making section, and by setting up a bag storage mechanism to store the bags processed in the bag making section. This ensures that the bag making section is continuous and uninterrupted, and makes the production line speed the same as the production speed of the bag making section. Thus, without changing the bag making section, the production line speed can be increased by 1.2-1.4 times, so as to fully utilize the production capacity of the bag making section.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figures 1-28As shown, the embodiment one of the application proposes a high-speed soft bag large infusion production line, the rack 13 is provided with a bag making section, a bag transfer mechanism 8, a filling section, and a control system 19;

[0034] The bag making section includes a film feeding mechanism 1, a film pulling mechanism 3, a character pulling mechanism 2, a forming mechanism 4, an automatic interface feeding mechanism 16, an interface conveying mechanism 17, an interface welding mechanism 5, an interface cooling mechanism 6, and a bag output mechanism 7. The filling section includes a bag feeding mechanism 9, a filling mechanism 10, a sealing mechanism 11, a soft bag output mechanism 12, a bag conveying mechanism 14, and an automatic cover feeding mechanism 15. The specific process is as follows: the film feeding mechanism 1 and the film pulling mechanism 3 send the film 2111 to the character pulling mechanism 2 and the forming mechanism 4. The character pulling mechanism 2 prints the passing film 2111 with contents such as production batch number, production date, and product registration information. The forming mechanism 4 processes the interface sent by the automatic interface feeding mechanism 16 and the interface conveying mechanism 17 and heated by the interface preheating mechanism 18 into a bag 211. Then the bag 211 passes through the interface welding mechanism 5, the interface cooling mechanism 6, and the bag output mechanism 7, and is sent to the bag transfer mechanism 8. The bag transfer mechanism 8 sends the bag 211 to the bag feeding mechanism 9 after turning it over. The bag conveying mechanism 14 sends the bag 211 to the filling mechanism 10 one by one, and fills the liquid medicine into it through the filling mechanism 10. Then the cover 212 can be moved to the interface through the automatic cover feeding mechanism 15, and is sealed by the sealing mechanism 11 through heating and welding to complete the sealing work. Finally, the processed soft bag large infusion 21 is output through the soft bag output mechanism 12 to complete the processing. The above structure and working principle are disclosed in the prior art (utility model with publication number CN101417712A). The technical features of the application further include:

[0035] The number of working units in each mechanism in the filling section is 1.5 times the number of working units in each mechanism in the bag making section. The working unit is the smallest station in each mechanism, such as Figure 1 As shown, the number of bags 211 completed by the filling section at one time is 1.5 times that of the bag making section, i.e. 9 (it can also be 12, 6, and the corresponding bag making section is 8, 4). The bag making section remains unchanged at 6.

[0036] The bag storage mechanism 20 is arranged above the bag making section, and the bag storage mechanism 20 is located above the bag discharging mechanism 7. The bag storage mechanism 20 can store the bags 211 processed by the bag making section. The number of working units on the bag storage mechanism 20 is twice the number of working units of the bag making section. The bag storage mechanism 20 can continuously receive and store the bags 211 sent by the bag making section twice, that is, (2X6=12 bags). The bag transfer mechanism 8 can take out 9 bags 211 (the same as the number of bags 211 processed by the filling section each time) and send them into the bag feeding mechanism 9. Then, under the conveying of the bag conveying mechanism 14, the bags 211 enter the filling mechanism 10 to fill the infusion. At this time, there are still 3 bags 211 in the bag storage mechanism 20. As shown in Figure 7 , then the bag storage mechanism 20 can again receive and store 6 bags 211 processed by the bag making section. Finally, the bag transfer mechanism 8 takes out 9 bags 211 again (3 bags 211 left + 6 bags 211) and sends them into the bag feeding mechanism 9. In this way, the bag making section can continuously work without interruption.

[0037] The present application increases the number of bags 211 processed by each mechanism of the filling section each time to 1.5 times the number of bags 211 processed by each mechanism of the bag making section, and cooperates with the bag storage mechanism 20 to store the bags 211 processed by the bag making section, so as to solve the problem that the processing time of the bag making section is inconsistent with the processing time of the filling section. The bag making section can continuously work without interruption, the speed of the production line is the same as the production speed of the bag making section, so that the speed of the production line can be increased by 1.2-1.4 times without changing the bag making section, so as to fully exert the production capacity of the bag making section.

[0038] In the first embodiment, the bag storage mechanism 20 includes a fixed frame 2004 arranged on the rack 13. The fixed frame 2004 is provided with a driving synchronous wheel 2002 and a driven synchronous wheel 2008. Both the driving synchronous wheel 2002 and the driven synchronous wheel 2008 are rotatably arranged on the fixed frame 2004 and are connected by a synchronous belt 2003. The driving synchronous wheel 2002 is driven to rotate by a servo driving unit 2001. The servo driving unit 2001 controls the servo motor to rotate forward and reverse. The fixed frame 2004 is provided with a guide rail 2007. A plurality of positioning sliding blocks 2006 are slidingly connected to the guide rail 2007. The positioning sliding blocks 2006 are connected to the synchronous belt 2003. The bag clamps 2005 are arranged on the positioning sliding blocks 2006. The working process is as shown in Figures 5 to 10 , that is, the bags 211 from the bag discharging mechanism 7 of the bag making section are pushed into the bag clamps 2005 of the bag storage mechanism 20 by the bag pushing mechanism 82. As shown in Figure 5As shown, at this time, the servo drive unit 2001 drives the driving sprocket 2003 to rotate counterclockwise, driving the synchronous belt 2003, the positioning slider 2006 and the bag gripper 2005 to move left by one group (6 bags 211), and after the next bag 211 made in the bag making section enters the bag pushing-out mechanism 7, the bag 211 is pushed into the bag gripper 2005 in the bag storage mechanism 20 by the bag pushing-out mechanism 82, as shown in Figure 6 As shown, after 2 groups of bags 211 (2X6=12) are stored in the bag storage mechanism 20, 9 bags 211 (same as the number of bags 211 completed in the filling section each time) are taken out by the bag transfer mechanism 8 and sent into the bag feeding mechanism 9, and then the bags 211 enter the filling mechanism 10 under the conveying of the bag conveying mechanism 14, and at this time, there are still 3 bags 211 left in the bag storage mechanism 20, as shown in Figure 7 As shown, then the servo drive unit 2001 drives the driving sprocket 2003 to rotate clockwise, driving the synchronous belt 2003, the positioning slider 2006 and the bag gripper 2005 to move right by half a group (3 bags 211), as shown in Figure 8 As shown, after the next bag 211 made in the bag making section enters the bag pushing-out mechanism 7, the bag 211 is pushed into the bag gripper 2005 in the bag storage mechanism 20 by the bag pushing-out mechanism 82, as shown in Figure 9 As shown, at this time, the bag storage mechanism 20 stores 1.5 groups of bags 211 (1.5X6=9), the bag transfer mechanism 8 takes out 9 bags 211 and sends them into the bag feeding mechanism 9, and at the same time, the servo drive unit 2001 drives the driving sprocket 2003 to rotate clockwise (if the bag gripper 2005 on the bag storage mechanism is full, i.e., the bag gripper 2005 is evenly arranged in 4 groups or more, this step can be omitted), driving the synchronous belt 2003, the positioning slider 2006 and the bag gripper 2005 to move right by half a group (3 bags 211), as shown in Figure 10 As shown, return to the starting point, and after the next bag 211 made in the bag making section enters the bag pushing-out mechanism 7, the bag storage mechanism 20 works in this way, ensuring that the bags 211 completed in the bag making section are sent into the bag transfer mechanism 8 in time, and since the number of bags 211 completed in the filling section each time is 1.5 times that of the bag making section, and the time is only 1.2 times that of the bag making section, the production capacity of the filling section is larger than that of the bag making section, thereby ensuring that the speed of the production line is the same as that of the bag making section.
