Abstract
Description
Technical Field
[0001] This application relates to the technical field of medical product manufacturing, and more specifically, to a filling device and control method for tubular infusion products. Background Technology
[0002] Non-PVC series tubular infusion products are generally produced by a linear staggered fully automatic bag making and sealing machine. Its main process includes film feeding, tubing feeding, bag making, tube heat sealing, waste edge removal, bag transfer, filling, stoppering, and bag output. The clamp transfers the unfilled soft bag to the filling station, initiating the filling process. First, the filling nozzle is inserted into the tubing opening on the soft bag, and then filling begins. The quick-fill valve opens, and the liquid flows from the filling nozzle, along the tubing, into the filling chamber. Once the set volume is reached, the quick-fill valve closes, the filling nozzle leaves the tubing, and the filling process ends.
[0003] Currently, during the production and filling process of tubular infusion products, it is easy for the soft bag to fall and cause the medicine to splash. According to the Good Manufacturing Practice for Pharmaceuticals, after the medicine splashing causes pollution to the site environment, the production environment must be restored before production can continue.
[0004] The splashing of tubular infusion products during filling is influenced by multiple factors, including high temperatures of the filling solution making the tubing flexible and difficult to clamp, and excessive filling pressure causing the bag to detach. If there are no flexible bags on the clamps at the filling station, or if a flexible bag falls off during filling, the filling nozzle will continue to fill the solution, resulting in splashing and waste of the solution.
[0005] In conclusion, how to reduce splashing waste during the filling of soft bag products with liquid medicine is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0006] In view of this, the purpose of this application is to provide a filling device and control method for tubular infusion products, which can effectively reduce splashing waste during the filling process of soft bag products.
[0007] To achieve the above objectives, this application provides the following technical solution:
[0008] A tubular infusion product filling device includes a frame, a conveying clamp, and a filling nozzle. The conveying clamp and the filling nozzle are both slidably connected to the frame. The conveying clamp is used to hold the tubing on the soft bag, and the filling nozzle is used to coaxially insert into the tubing on the soft bag. It also includes a detection component, which is electrically connected to the control system of the filling nozzle. The detection component is used to detect whether the filling nozzle has successfully docked with the tubing on the soft bag.
[0009] Preferably, the conveying clamp includes a sliding block and an opening and closing gripper, the opening and closing gripper is located on one side of the sliding block, the frame is provided with a conveying slide for the sliding block to slide and engage, and the axis of the hose on the soft bag is perpendicular to the length direction of the conveying slide.
[0010] Preferably, the sliding direction of the filling nozzle is parallel to and vertical to the axis of the hose on the soft bag, and the nozzle tip end face edge is provided with a chamfer.
[0011] Preferably, the opening and closing direction of the opening and closing gripper is parallel to the moving direction of the conveying clamp, an auxiliary support platform is fixedly provided on the frame, the auxiliary support platform and the conveying slide are respectively located on opposite sides of the flexible tube of the soft bag, and the table surface of the auxiliary support platform is in contact with the lower side of the opening and closing gripper.
[0012] Preferably, the detection component includes a contact block, a first control element, and a second control element. The first control element and the second control element are used to move the contact block and the frame relative to each other. The control direction of the first control element and the control direction of the second control element are both horizontal and perpendicular to each other. The control direction of the first control element or the second control element is parallel to the movement direction of the conveying fixture.
[0013] Preferably, the first control component is a gripper power cylinder, and there are two contact blocks respectively connected to the two output ends of the gripper power cylinder. The relative movement direction of the two contact blocks is parallel to the movement direction of the conveying fixture. The second control component is used to control the movement of the gripper power cylinder.
[0014] Preferably, the contact block has a mating groove, the bottom of which is used to abut against the outer wall of the flexible tube of the soft bag.
[0015] Preferably, a force sensor is provided inside the contact block, and the force sensor is electrically connected to the control system of the filling nozzle.
[0016] Preferably, the second control component is a push-pull power cylinder, which is connected to the frame, and the output end of the push-pull power cylinder is connected to the gripper power cylinder.
[0017] A method for controlling the filling of a tubular infusion product, using the aforementioned tubular infusion product filling device, includes:
[0018] The conveying clamp transports the soft bag to the filling station and stops moving, so that the nozzle of the filling nozzle is aligned with the tube opening on the soft bag;
[0019] The filling nozzle moves closer to the hose, the nozzle is inserted into the hose, and the first control and the second control control move the two contact blocks to both sides of the hose and move towards the filling nozzle.
[0020] The contact blocks are located above the conveying clamp. When the two contact blocks abut against the hose, the conveying clamp releases the hose, and the force sensor sends a working signal to the control system of the filling nozzle, and the filling nozzle begins to spray the liquid medicine.
[0021] If the contact block does not come into contact with any object, the filling nozzle will not spray the liquid, and the detection component will issue an alarm signal.
[0022] After the liquid spraying is completed, the delivery clamp clamps the hose again, and then the filling nozzle exits from the hose, while the contact block and the hose disengage.
[0023] The tubular infusion product filling device provided in this application uses a conveying clamp to sequentially transport multiple soft bags to be filled to the filling station, i.e., the filling nozzle. Then, the filling nozzle moves toward the tubular opening of the soft bag and inserts into it. The detection component detects whether a tubular tube is present outside the filling nozzle. If it is, the filling nozzle and the tubular tube are in a docking state, and a working signal is sent to the control system of the filling nozzle to spray the medicine. If it is not present, it indicates that the two have not successfully docked, and the filling nozzle cannot spray the medicine into the soft bag. Regardless of whether there is a soft bag at this point, no working signal is sent, reducing the occurrence of filling failures and thus reducing the waste of medicine splashing.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

The terms "first," "second," and similar words used in this application do not indicate any order, quantity, or importance. Terms such as "connection" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly. This application discloses a tubular infusion product filling device and control method.
[0032] The core of this application is to provide a filling device and control method for tubular infusion products.
[0033] Please refer to Figures 1-3 .
[0034] The tubular infusion product filling device provided in this application includes a frame 1, a conveying clamp 3, a filling nozzle 4, and a detection component 5. The conveying clamp 3 is used to convey the soft bag 2. Both the conveying clamp 3 and the filling nozzle 4 are slidably connected to the frame 1. Multiple conveying clamps 3 are arranged horizontally, and the arrangement direction of the conveying clamps 3 is their moving direction. All conveying clamps 3 move synchronously. The filling nozzle 4 is located at the spraying station. Each conveying clamp 3 takes turns passing through the spraying station, delivering the soft bag 2 it carries to the spraying station for liquid filling.
[0035] The soft bag 2 has two independent cavities and two fixed hoses 21. Each hose 21 is connected to one cavity, and the axes of the two hoses 21 are parallel to each other. Two conveying clamps 3 form a group, and each clamp applies a clamping force to the two hoses 21 of the soft bag 2. Correspondingly, the filling nozzle 4 also has two nozzles, each corresponding to a hose 21. When the soft bag 2 moves to the correct position at the filling station, the conveying clamps 3 remain stationary, and the filling nozzle 4 moves closer to the soft bag 2, with the two nozzles respectively inserted into the openings of the hoses 21.
[0036] The spraying of the medicine does not begin immediately after the nozzle is inserted into the hose 21. The detection component 5 is used to detect whether the nozzle of the filling nozzle 4 has successfully connected with the hose 21. The detection component 5 is electrically connected to the control system of the filling nozzle 4, and the detection result of the detection component 5 determines whether to spray the medicine. In order to improve the sealing at the medicine spraying interface, in the case of successful connection, the nozzle of the filling nozzle 4 should have an axially overlapping part with the hose 21, that is, the end of the nozzle of the filling nozzle 4 needs to be inserted into the hose 21 for a certain distance.
[0037] Therefore, the detection component 5 is used to detect whether there is a hose 21 outside the filling nozzle 4. If it exists, it means that the filling nozzle 4 and the hose 21 are in a docking state and are well sealed, thereby sending a working signal to the control system of the filling nozzle 4 to spray the medicine. If it does not exist, it means that the two have not been successfully docked, and the filling nozzle 4 cannot spray the medicine into the soft bag 2. Regardless of whether there is a soft bag 2 here, no working signal is sent, reducing the occurrence of filling failure and thus reducing the waste of medicine splashing.
[0038] The following description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed account of the tubing 21 infusion product filling device and control method provided in this application.
[0039] In one specific implementation, reference is made to... Figure 1 .
[0040] Specifically, the conveying clamp 3 includes a sliding block 31 and opening / closing grippers 32. The opening / closing grippers 32 are located on one side of the sliding block 31, and the sliding block 31 has a built-in gripper cylinder (not shown in the figure) for controlling the opening and closing movement of the opening / closing grippers 32. The opening / closing grippers 32 have semi-circular clamping grooves 321. When the soft bag 2 is clamped and fixed, the bottom of the clamping grooves 321 of the two opening / closing grippers 32 respectively abut against the opposite sides of the hose 21, and at this time the axis of the hose 21 is perpendicular to the moving direction of the conveying clamp 3.
[0041] The frame 1 is provided with a conveyor slide 11 for sliding cooperation of the sliding block 31. The conveyor slide 11 has a built-in drive mechanism that drives each conveyor clamp 3 to move synchronously through chain transmission. The direction of movement is horizontal.
[0042] Based on the above embodiments, refer to Figures 1-3 .
[0043] Specifically, the sliding direction of the filling nozzle 4 is parallel to and vertical to the axis of the hose 21 on the soft bag 2, that is, the filling nozzle 4 moves downward so that its nozzle head is inserted into the hose 21. In order to improve the success rate of insertion, the lower end face edge of the filling nozzle 4 is provided with an insertion chamfer 41. The insertion chamfer 41 reduces the radial dimension of the lower end of the nozzle, increases the dimensional allowance relative to the shaft, and facilitates smooth entry into the opening of the hose 21.
[0044] Based on the above embodiments, refer to Figure 1 .
[0045] Specifically, the opening and closing direction of the opening and closing gripper 32 is parallel to the moving direction of the conveying clamp 3. An auxiliary support platform 12 is fixedly installed on the frame 1. The auxiliary support platform 12 is a long and slender platform with its length direction parallel to the conveying slide 11.
[0046] The auxiliary support platform 12 has a polished smooth surface. The auxiliary support platform 12 and the conveying slide 11 are located on opposite sides of the flexible tube 21 of the soft bag 2. The platform of the auxiliary support platform 12 is in contact with the lower side of the opening and closing gripper 32. For the conveying clamp 3, its connection point with the frame 1 is the conveying slide 11. When the opening and closing gripper 32 bears the weight, its force structure is not stable. Therefore, the platform of the auxiliary support platform 12 supports and abuts it on the other side. Thus, vertical support points are formed on both sides of the flexible tube 21 on the conveying clamp 3, which improves the force stability of the conveying clamp 3 and the posture stability of the conveying clamp 3.
[0047] Based on the above embodiments, refer to Figure 1 .
[0048] Specifically, the detection component 5 includes a contact block 51, a first control element 52, and a second control element 53. The first control element 52 and the second control element 53 are used to move the contact block 51 relative to the frame 1. The control direction of the first control element 52 and the control direction of the second control element 53 are both horizontal and perpendicular to each other. If the control direction of one of the two control elements is parallel to the movement direction of the conveying clamp 3, then the control direction of the other control element is perpendicular to the movement direction of the conveying clamp 3. The two cooperate with each other so that the contact block 51 can move laterally closer to or further away from the filling station. It can approach the hose 21 for contact detection, or it can create space for the conveying clamp 3 to continue moving with the soft bag 2.
[0049] Based on the above embodiments, refer to Figure 1 .
[0050] Specifically, the first control element 52 is an electric gripper power cylinder, and there are two contact blocks 51 connected to the two output ends of the gripper power cylinder respectively. The relative movement direction of the two contact blocks 51 is parallel to the movement direction of the conveying fixture 3.
[0051] The second control element 53 is used to control the movement of the gripper power cylinder. The movement direction is perpendicular to the length direction of the conveying slide 11. Under the control of the second control element 53, the first control element 52 moves to the position where the two contact blocks 51 are located on the front and rear sides of the hose 21 respectively. Then the gripper power cylinder can be activated to make the contact blocks 51 abut against the hose 21.
[0052] Based on the above embodiments, refer to Figure 1 .
[0053] Specifically, a mating groove 511 is provided on the side of the contact block 51 facing the hose 21. The mating groove 511 is a semi-circular groove. When the two contact blocks 51 abut against the hose 21, the bottom of the mating groove 511 is used to abut against the outer wall of the hose 21 of the soft bag 2. That is, the mating groove 511 improves the degree of contact and fit between the two and also reduces the excessive concentration of the abutment force.
[0054] Based on the above embodiments, refer to Figure 1 and Figure 3 .
[0055] Specifically, a force sensor is installed inside the contact block 51, and the force sensor is electrically connected to the control system of the filling nozzle 4. In this embodiment, as the two contact blocks 51 move close to the hose 21, the diameter of the circular space formed by the two mating grooves 511 at the end of their stroke is smaller than the outer diameter of the hose 21 and larger than the nozzle diameter of the filling nozzle 4. Therefore, after the contact block 51 touches the hose 21, it will be subjected to an abutting force from the side wall of the hose 21. Then, the force sensor transmits the force signal to the control system of the filling nozzle 4 as a working signal.
[0056] Based on the above embodiments, refer to Figure 1 .
[0057] Specifically, the second control component 53 is a push-pull power cylinder, which is connected to the frame 1, and its output end is connected to the rod of the gripper power cylinder. In this embodiment, the push-pull power cylinder is a pneumatic cylinder, and its piston rod extends and retracts in a horizontal direction and is perpendicular to the length direction of the conveying slide 11.
[0058] The tubular infusion product filling control method provided in this application is based on the aforementioned tubular infusion product filling device, with reference to... Figure 3 The steps are as follows:
[0059] S1: The conveying clamp 3 transports the soft bag 2 to the filling station and is directly below the filling nozzle 4 and stops moving, so that the two nozzles of the filling nozzle 4 are coaxially aligned with the openings of the two hoses 21 on the soft bag 2.
[0060] S2: The filling nozzle 4 moves closer to the hose 21 and the nozzle is inserted into the corresponding hose 21, but the lower end of the filling nozzle 4 does not reach the opening and closing claw 32. The second control unit 53 controls the contact block 51 to move to both sides of the hose 21, and the first control unit 52 causes the two contact blocks 51 to move towards the filling nozzle 4.
[0061] S3: Contact block 51 is located above conveying clamp 3. In this embodiment, the outer diameter of hose 21 is 8.2mm, the nozzle diameter of filling nozzle 4 and the inner diameter of hose 21 are both 6.2mm. When the two contact blocks 51 move close to each other to the end of their stroke, the diameter of the circular space formed by the two mating grooves 511 is 7mm. When the two contact blocks 51 abut against hose 21, the contact blocks 51 are also subjected to abutting force from the side wall of hose 21. The force sensor can detect the force state of the contact blocks 51. At this time, the conveying clamp 3 releases hose 21, and the force sensor sends a working signal to the control system of filling nozzle 4, and filling nozzle 4 begins to spray liquid medicine. If the contact block 51 does not abut against any object when it moves to the end of its stroke, it indicates that hose 21 and filling nozzle 4 have not successfully docked. Filling nozzle 4 does not spray liquid medicine because it has not received a working signal from detection component 5. At the same time, detection component 5 issues an alarm signal to remind the staff to check.
[0062] S4: After the liquid spraying is completed, the conveying clamp 3 clamps the hose 21 again, the filling nozzle 4 exits from the hose 21, and at the same time the contact block 51 and the hose 21 are separated, the filling process ends, and the conveying clamp 3 carries the hose 21 and the soft bag 2 to the subsequent work station.
[0063] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
[0064] The foregoing has provided a detailed description of a tubular infusion product filling device and control method. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.
