Description

Technical Field

[0001] The present application relates to the technical field of pharmaceutical equipment, and in particular to a high-speed soft bag large infusion production line. Background Art

[0002] The existing soft bag large infusion production line can be seen in the technical solution disclosed in publication number CN101417712A, such as Fig.28 As shown: the soft bag large infusion 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 arranged 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 discharging mechanism 7 and the bag feeding mechanism 9 coincide with each other; the bag making section is mainly composed 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 discharging mechanism 7, an automatic interface supply mechanism 16, an interface conveying mechanism 17 and an interface preheating mechanism 18, and the filling section is mainly composed of a bag feeding mechanism 9, a filling mechanism 10, a cap welding mechanism 11, a bag placing mechanism 12, a bag conveying mechanism 14 and an automatic cap feeding mechanism 15, and its working process is: 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 the production batch number, production date, product registration information and the like on the film 2111 passing through. The forming mechanism 4 processes the interface 2112 and the film 2111 sent by the automatic interface supply mechanism 16 and the interface conveying mechanism 17 and heated by the interface preheating mechanism 18 into a bag 211; the bag 211 is sent to the bag transfer mechanism 8 through the interface welding mechanism 5, the interface cooling mechanism 6 and the bag discharging mechanism 7. The bag transfer mechanism 8 turns the bag 211 90 degrees and then sends it to the bag feeding mechanism 9. The bag conveying mechanism 14 sends the bag 211 to the filling mechanism 10 (where the liquid medicine is poured in) and the cap welding mechanism 11 (where the cap 212 sent by the automatic cap feeding mechanism 15 is welded to the bag 211), and the bag unloading mechanism 12 takes the soft bag large infusion 21 out of the bag conveying mechanism 14 to complete the production of the soft bag large infusion 21.

[0003] In the actual production process, it is found that the filling process takes about 1.2-1.4 times the time of the bag making process. Fig.28 It can be seen that the bag making section and the filling section complete the same number of bags at a time, that is, 6. In this way, the production speed of the filling section is the speed of the entire production line. That is, after the bag making section completes the bag making, it needs to wait for the filling section to complete the filling before it can make bags again. This results in the production capacity of the bag making section not being fully utilized. In order to reasonably improve this problem, this application proposes a high-speed soft bag large infusion production line Summary of the invention

[0004] The purpose of this application is to solve the problem that in the actual production process of the prior art, the time taken in the filling section is about 1.2-1.4 times that taken in the bag making section. Fig.28 It can be seen that the number of bags completed at one time in the bag making section and the filling section is the same, that is, 6. In this way, the production speed of the filling section is the speed of the entire production line. That is, 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. This leads to the technical problem that the production capacity of the bag making section is not fully utilized. The present application provides a high-speed soft bag large infusion production line.

[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0008] Furthermore, the bag storage mechanism includes a fixed frame arranged on the frame, a driving synchronous wheel and a driven synchronous wheel are installed on the fixed frame, the two are connected by a synchronous belt transmission, and are equipped with a servo drive unit for driving the driving synchronous wheel to rotate, a guide rail is provided on the fixed frame, the guide rail is slidably matched with a plurality of positioning sliders, and the plurality of positioning sliders are all connected to the synchronous belt, and a bag clamp is provided on the positioning slider.

[0009] Furthermore, the bag storage mechanism includes a fixed frame arranged on the frame, a linear drive is installed on the fixed frame, and a servo drive unit is equipped to drive the linear drive to move. A connecting piece is slidably fitted on the fixed frame and connected to the output end of the linear drive, and a plurality of bag clamps are linearly distributed on the connecting piece.

[0010] Furthermore, the bag transfer mechanism has a turnover beam, and the fixing frame is installed on the turnover beam.

[0011] The beneficial effects of the present application are as follows: the present application solves the problem of inconsistent single processing time between the bag making section and the filling section by increasing the number of bags completed at a time in each mechanism of the filling section to 1.5 times the number of bags completed by each mechanism of the bag making section, and coordinating the provision of a bag storage mechanism to store bags processed in the bag making section, thereby ensuring that the bag making section is continuous and uninterrupted, and making the speed of the production line the same as the production speed of the bag making section, thereby increasing the speed of the production line 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.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0032] Embodiment 1

[0033] like Figure 1-Figure 28As shown, a high-speed soft bag large infusion production line proposed in the first embodiment of the present application includes a frame 13 on which a bag making section, a bag transfer mechanism 8, a filling section, and a control system 19 are provided;

[0034] The bag making section includes a film feeding mechanism 1, a film drawing mechanism 3, a printing mechanism 2, a forming mechanism 4, an automatic interface supply mechanism 16, an interface conveying mechanism 17, an interface welding mechanism 5, an interface cooling mechanism 6 and a bag discharging mechanism 7; the filling section includes a bag feeding mechanism 9, a filling mechanism 10, a sealing mechanism 11, a soft bag discharging mechanism 12, a bag conveying mechanism 14 and an automatic cover supplying mechanism 15. The specific process is as follows: the film feeding mechanism 1 and the film drawing mechanism 3 feed the film 2111 into the printing mechanism 2 and the forming mechanism 4; the printing mechanism 2 prints the contents such as the production batch number, the production date, and the product registration information on the film 2111; the forming mechanism 4 connects the interface sent by the automatic interface supply mechanism 16 and the interface conveying mechanism 17 and heated by the interface preheating mechanism 18 with the film 211 1 is processed into a bag 211, and then the bag 211 passes through the interface welding mechanism 5, the interface cooling mechanism 6 and the bag discharging mechanism 7, and is sent to the bag transfer mechanism 8. The bag transfer mechanism 8 flips the bag 211 and sends it to the bag feeding mechanism 9. The bag conveying mechanism 14 sends the bag 211 to the filling mechanism 10 in sequence, and the liquid medicine is poured into it through the filling mechanism 10. Then, the cover 212 can be moved to the interface by the automatic cover supply mechanism 15, and the sealing mechanism 11 heats and welds it to complete the sealing work. Finally, the soft bag large infusion 21 processed 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 (the invention of publication number CN101417712A). The distinguishing technical features of this application also 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 at one time in the filling section is 1.5 times that of the bag making section, that is, 9 (it can also be 12 or 6, and the corresponding number of bags in the bag making section is 8 or 4), while the number of bags in the bag making section remains unchanged at 6;

[0036] A bag storage mechanism 20 is added and arranged above the bag making section. The bag storage mechanism 20 is located above the bag discharging mechanism 7. The bags 211 processed in the bag making section can be stored through the bag storage mechanism 20. The number of working units on the bag storage mechanism 20 is twice the number of working units in the bag making section. The bags 211 sent from the bag making section can be received and stored twice in succession through the bag storage mechanism 20, that is, (2X6=12). 9 bags 211 (the same number as the number of bags 211 completed each time in the filling section) can be taken out through the bag transfer mechanism 8 and sent to the bag feeding mechanism 9. Then, the bags 211 are transported by the bag conveying mechanism 14 and enter the filling mechanism 10 for filling and infusion. At this time, there are 3 bags 211 left in the bag storage mechanism 20. Figure 7 As shown, the bag storage mechanism 20 can then receive and store the six bags 211 processed by the bag-making section, and finally take out nine bags 211 (three bags 211 + six bags 211 remaining) through the bag transfer mechanism 8 and send them to the bag feeding mechanism 9, thereby ensuring that the bag-making section is not interrupted in production.

[0037] The present application solves the problem of inconsistent single processing time between the bag making section and the filling section by increasing the number of bags 211 completed at a time by each mechanism in the filling section to 1.5 times the number of bags 211 completed at a time by each mechanism in the bag making section, and arranging a bag storage mechanism 20 to store the bags 211 processed in the bag making section, thereby ensuring that the bag making section is continuous and uninterrupted, and making the speed of the production line the same as the production speed of the bag making section. Therefore, without changing the bag making section, the speed of the production line can be increased by 1.2-1.4 times 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 frame 13, and an active synchronous wheel 2002 and a driven synchronous wheel 2008 are installed on the fixed frame 2004, both of which are rotatably installed on the fixed frame 2004, and the two are connected by a synchronous belt 2003, and are equipped with a servo drive unit 2001 for driving the active synchronous wheel 2002 to rotate. The active synchronous wheel 2002 is driven to rotate by a servo motor, and the servo drive unit 2001 controls the servo motor to rotate forward and reverse. A guide rail 2007 is provided on the fixed frame 2004, and the guide rail 2007 is slidably matched with a plurality of positioning sliders 2006, and the plurality of positioning sliders 2006 are connected to the synchronous belt 2003, and a bag clamp 2005 is provided on the positioning slider 2006. Its working process is as follows: Figures 5 to 10 As shown, the bag 211 from the bag discharging mechanism 7 of the bag making section is pushed into the bag clamp 2005 in the bag storage mechanism 20 by the bag pushing mechanism 82, as shown in FIG. Figure 5As shown, at this time, the servo drive unit 2001 drives the active synchronous belt 2003 to rotate counterclockwise, driving the synchronous belt 2003, the positioning slider 2006 and the bag clamp 2005 to move one group (6 bags 211) to the left. After the next bag 211 made in the bag making section enters the bag outlet mechanism 7, the bag 211 is pushed into the bag clamp 2005 in the bag storage mechanism 20 by the bag push-out mechanism 82 again, as shown in FIG. Figure 6 As shown, after two groups of bags 211 (2×6=12 bags) are stored in the bag storage mechanism 20, nine bags 211 (the same number as the number of bags 211 completed each time in the filling process) can be taken out by the bag transfer mechanism 8 and sent to the bag feeding mechanism 9. Then, the bags 211 are transported by the bag conveying mechanism 14 and enter the filling mechanism 10 for filling and infusion. At this time, there are still three bags 211 left in the bag storage mechanism 20. Figure 7 As shown, the servo drive unit 2001 then drives the active synchronous belt 2003 to rotate clockwise, driving the synchronous belt 2003, the positioning slider 2006 and the bag clamp 2005 to move half a group (3 bags 211) to the right, as shown in FIG. Figure 8 As shown, after the next bag 211 made in the bag making section enters the bag discharging mechanism 7, the bag 211 is pushed into the bag clamp 2005 in the bag storage mechanism 20 by the bag pushing mechanism 82 again, as shown in FIG. Fig. 9 As shown, at this time, 1.5 groups of bags 211 (1.5X6=9) are stored in the bag storage mechanism 20, and the bag transfer mechanism 8 takes out 9 bags 211 and feeds them into the bag feeding mechanism 9. At the same time, the servo drive unit 2001 drives the active synchronous belt 2003 to rotate clockwise (if the bag clamps 2005 on the bag storage mechanism are full, that is, more than 4 groups of bag clamps 2005 are evenly arranged, this step can be omitted), driving the synchronous belt 2003, the positioning slider 2006 and the bag clamps 2005 to move half a group (3 bags 211) to the right, as shown in FIG. Fig.10 As shown, it returns to the starting state and waits for the next bag 211 made in the bag-making section to enter the bag-discharging mechanism 7. In this way, the bag storage mechanism 20 works in this way in a cycle to ensure that the bags 211 completed in the bag-making section are immediately delivered to the bag transfer mechanism 8. 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 greater 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.

[0039] Embodiment 2

[0040] like Figure 1-Figure 23As shown, the second embodiment is another embodiment of the bag storage mechanism 20 in the first embodiment of the present application. The bag storage mechanism 20 includes a fixed frame 2004 arranged on the frame 13, and a linear drive 20010 is installed on the fixed frame 2004. The linear drive 20010 is a synchronous toothed belt or a screw rod, and is equipped with a servo drive unit 2001 for driving the linear drive 20010 to move. A connecting piece 2009 is slidably matched on the fixed frame 2004, and the connecting piece 2009 can be tubular or plate-shaped. And connected to the output end of the linear drive 20010, a plurality of bag clips 2005 are linearly distributed on the connecting piece 2009. It should be specifically explained here that if the linear drive 20010 is provided with a guide rail 2007, the connecting piece 2009 can be directly installed on the slider of the linear drive 20010. If the linear drive 20010 is not provided with a guide rail 2007, the connecting piece 2009 needs to be installed on the slider of the pair of linear guide rails 2007 fixed on the fixing frame 2004. The working process is as follows: Figures 14 to 19 As shown, the bag 211 from the bag discharging mechanism 7 of the bag making section is pushed into the bag clamp 2005 in the bag storage mechanism 20 by the bag pushing mechanism 82, as shown in FIG. Fig.14 As shown, at this time, the servo drive unit 2001 drives the linear drive 20010 to drive the connecting piece 2009 and the bag clamp 2005 to move one group (6 bags 211) to the left. After the next bag 211 made in the bag making section enters the bag discharging mechanism 7, the bag 211 is pushed into the bag clamp 2005 in the bag storage mechanism 20 by the bag pushing mechanism 82 again. Fig.15 As shown, at this time, two groups of bags 211 (2X6=12 bags) are stored in the bag storage mechanism 20, and the bag transfer mechanism 8 takes out 9 bags 211 (the same number of bags 211 completed each time in the filling section) and sends them to the bag feeding mechanism 9. The bags 211 are transported by the bag conveying mechanism 14 into the filling mechanism 10 for filling and infusion. At this time, there are 3 bags 211 left in the bag storage mechanism 20, and then the servo drive unit 2001 drives the linear drive 20010 to drive the connecting piece 2009 and the bag clamp 2005 to move half a group (3 bags 211) to the right, as shown in FIG. Fig.17 As shown, after the next bag 211 made in the bag making section enters the bag discharging mechanism 7, the bag 211 is pushed into the bag clamp 2005 in the bag storage mechanism 20 by the bag pushing mechanism 82 again. Fig.18 As shown, at this time, 1.5 groups of bags 211 (1.5X6=9 bags) are stored in the bag storage mechanism 20, and the bag transfer mechanism 8 takes out 9 bags 211 and feeds them into the bag feeding mechanism 9. At the same time, the servo drive unit 2001 drives the linear drive 20010 to drive the connecting member 2009 and the bag clamp 2005 to move half a group (3 bags 211) to the right. Fig.19As shown, it returns to the starting state and waits for the next bag 211 made in the bag making section to enter the bag discharging mechanism 7. In this way, the bag storage mechanism 20 works in a cycle to ensure that the bags 211 completed in the bag making section are immediately delivered to the bag transfer mechanism 8.

[0042] like Figure 20-23 As shown, the third embodiment further improves the present application on the basis of the first embodiment, the bag transfer mechanism 8 has a turning beam 801, and the fixing frame 2004 is installed on the turning beam 801. The specific structure of the third embodiment is the same as that of the first embodiment, and its working process is also the same as that of the first embodiment. The difference between the third embodiment and the first embodiment lies in that the fixing frame 2004 of the bag storage mechanism 20 of this scheme is installed on the turning beam 801 of the bag transfer mechanism 8, replacing the function of the clamping device in the bag transfer mechanism 8 of the prior art, that is, the bag storage mechanism 20 can store the bags 211 sent from the bag making section, and can also distribute the number of bags 211 completed in a single filling section, and send them to the filling section by the bag transfer mechanism 8 (the structure and working principle of the bag transfer mechanism 8 can refer to the fifth embodiment in the technical scheme disclosed in the publication number CN101417712A).

[0044] like Figure 1-Figure 23 As shown, the fourth embodiment further improves the present application on the basis of the second embodiment, the bag transfer mechanism 8 has a flip beam 801, and the fixing frame 2004 is installed on the flip beam 801. The specific structure of the fourth embodiment is the same as that of the second embodiment, and its working process is also the same as that of the second embodiment. The difference between the fourth embodiment and the second embodiment is that the fixing frame 2004 of the bag storage mechanism 20 of this scheme is installed on the flip beam 801 of the bag transfer mechanism 8, replacing the function of the clamping device in the bag transfer mechanism 8 of the prior art.
