Description

Technical Field

[0001] This application relates to the field of medical supplies production equipment technology, and more specifically, to an automatic feeding system for barrelled aseptic powder. Background Technology

[0002] Sterile powder refers to a dry powder or lumpy substance made from raw materials or excipients under strict aseptic conditions, intended for injection after being dissolved or suspended in a suitable solvent before use.

[0003] Currently, the feeding and transfer of aseptic active pharmaceutical ingredients (APIs) typically takes place in sealed aseptic aluminum drums. The drums require sterilization and laminar flow transfer to the powder injection filling room for feeding. Existing operations mostly involve manual assistance for unloading, transfer to the filling room via laminar flow trolleys, and manual removal of the outer and inner caps and rubber stoppers under partial laminar flow protection in the filling room, followed by docking and inversion for feeding. Alternatively, the removal of the inner cap and docking / inversion for feeding can be partially automated within the filling room. These manual or semi-automatic methods require personnel to perform numerous operations in the filling room, and may even necessitate personnel entering the laminar flow area during production, introducing significant human interference and a certain risk of contamination.

[0004] In conclusion, how to improve the level of unmanned and automated operation in the aseptic powder feeding and transfer process is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0011] The feeding and docking device is located near the end of the feeding track and the beginning of the discharging track. The feeding and docking device includes a flipping mechanism and a receiving mechanism. The flipping mechanism is used to clamp the material bucket on the feeding track and bring the material bucket close to the receiving mechanism. The receiving mechanism includes a receiving pipe.

[0013] Preferably, the pick-and-place cap assembly further includes a displacement actuator, which is connected to the frame and located between the feed track and the discharge track. The displacement actuator is used to control the movement of the adsorbent and the adsorption drive source above the discharge track and above the feed track.

The valve core of the sealing valve controls the opening or closing of the opening of the material bucket. The receiving mechanism includes a valve opener. When the opening of the material bucket is sealed to the receiving pipe, the valve opener can control the valve core of the sealing valve to move and open the opening of the material bucket.

Upon passing the lid removal assembly, the lid of the drum is removed, leaving the drum open. A tilting mechanism then moves the drum to a receiving mechanism and tilts it. When the drum opening aligns with the receiving pipe, the powder inside is poured into the receiving pipe. After feeding is complete, the drum is emptied. The tilting mechanism then moves the empty drum back to the conveyor and places it on the discharge track. The lid removal assembly places the lid back into the drum opening, and the discharge track moves the empty drum away from the feeding docking device. The automatic feeding process for a single drum is then complete. The entire process of conveying, opening, tilting, feeding, closing, and removing is automated by individual devices or equipment, without human intervention or contact.

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.

This application discloses an automatic feeding system for aseptic powder in drums.

[0038] The core of this application is to provide an automatic feeding system for aseptic powder in drums, which can realize fully automated feeding of aseptic powder in drums, and has a high degree of automation and cleanliness.

[0039] Please refer to Figure 1 and Figure 2 .

[0040] The automatic feeding system for aseptic powder in drums provided in this application includes a frame 6, a conveying device 4, and a feeding docking device 12. The frame 6 serves as the overall load-bearing foundation and is a steel frame structure composed of several steel pipes, which has the characteristics of corrosion resistance and strong structural stability.

[0041] The conveying device 4 includes a feeding track 41 and a discharging track 42, both of which are fixedly installed at corresponding positions on the frame 6. The material bucket 7 can be directly placed on the surface of the feeding track 41 or the discharging track 42 and moves smoothly along the preset track trajectory to complete the material feeding and empty bucket discharging conveying. In specific implementation, the conveying device 4 is a conveying platform consisting of several rotating rollers arranged in an array along a set direction.

[0042] The feeding docking device 12 is located near the end of the feeding track 41 and the beginning of the discharging track 42. As the core feeding execution structure, it includes a flipping mechanism 1 and a receiving mechanism 3. The flipping mechanism 1 can independently clamp the fully loaded material bucket 7 that has been delivered to the feeding track 41 and drive the material bucket 7 to move closer to the receiving mechanism 3.

[0043] The receiving mechanism 3 includes a receiving pipe 31 for receiving the sterile powder poured from the material container 7. The tilting mechanism 1 can move and rotate the material container 7, so that the opening of the material container 7 and the end of the receiving pipe 31 are sealed together, thereby minimizing the leakage of powder and the entry of external air impurities into the joint gap during the feeding process. After the powder is fed into the material container 7, the tilting mechanism 1 reverses its movement, moving the empty material container 7 from the receiving mechanism 3 to the surface of the discharge track 42, completing the feeding and transfer connection of a single container of material. Then, the discharge track 42 carries the empty material container 7 away from the feeding and docking device 12.

[0044] The material hopper 7 has a lid, and a lid-removing assembly 5 is fixedly mounted on the frame 6. The lid-removing assembly 5 is arranged above the feeding track 41 and / or the discharging track 42. During the conveying of the material hopper 7 along the feeding track 41, the lid-removing assembly 5 can automatically remove the lid from the material hopper 7 on the feeding track 41, so that the opening of the material hopper 7 is completely open, meeting the conditions for subsequent feeding. After the material hopper 7 has been fed, turned into an empty hopper, and conveyed to the discharging track 42, the lid-removing assembly 5 can connect and close the removed lid to the opening of the empty material hopper 7 on the discharging track 42, realizing automatic sealing of the empty hopper.

[0045] The entire process of feeding and dispensing materials into the hopper 7, including transportation, opening, flipping, feeding, closing, and removal, is automated by various equipment or devices without human intervention or contact, thus achieving a high level of hygiene and cleanliness as well as high operational efficiency.

[0046] The automatic feeding system for aseptic powder in drums provided in this application will be described in more detail below with reference to the accompanying drawings and specific embodiments.

[0047] In one specific implementation, reference is made to... Figures 1-3 The lid-taking and placing assembly 5 is equipped with an adsorbent 51 and an adsorption drive source 52. The adsorbent 51 is movably mounted on the frame 6, and the adsorption drive source 52 can control the adsorbent 51 to move closer to or further away from the material tank 7. After the adsorbent 51 contacts the lid of the material tank 7, it can form a relatively fixed state with the lid through negative pressure adsorption, magnetic attraction, or mechanical locking, allowing the lid to move with the adsorbent 51. In this embodiment, the lid has an approximately disc-like structure (not shown in the figure), and the adsorbent 51 is a suction cup. After the suction cup and the top surface of the lid are attached, the lid can be fixed by negative pressure adsorption.

[0048] Based on this, a displacement actuator 54 is added to the pick-and-place cover assembly 5. The displacement actuator 54 is fixedly installed on the frame 6 and arranged between the feed track 41 and the discharge track 42. The displacement actuator 54 can drive the adsorbent 51 and the adsorption drive source 52 to move as a whole, so that the adsorbent 51 can switch back and forth between the working area above the feed track 41 and the working area above the discharge track 42. The two-stage operation of opening the cover at the feed end and sealing the cover at the discharge end can be completed with only one set of pick-and-place cover structure, simplifying the overall structure of the equipment.

[0049] In one specific implementation, such as Figures 1-3 As shown, the end of the feeding track 41 and the beginning of the discharging track 42 are arranged in parallel, and the installation height of the two tracks is consistent, that is, the height of the material buckets 7 on the two tracks is the same at this point. The position drive 54 is a rotary motor, which is fixedly installed on the frame 6 and located above the area between the feeding track 41 and the discharging track 42. The rotation axis of the rotary motor's output shaft is vertical. The position drive 54 is equipped with a connecting rod 53, which is fixedly connected to the output shaft of the rotary motor. The length direction of the connecting rod 53 is transverse, and the adsorption drive source 52 is fixedly assembled at the end of the connecting rod 53.

[0050] The rotator drives the connecting rod 53 to rotate horizontally through the output shaft, thereby causing the adsorbent 51 at the end and the adsorption drive source 52 to switch positions between above the feed track 41 and above the discharge track 42, meeting the needs of high-speed automated production.

[0051] Based on any of the above embodiments, refer to Figure 1 and Figure 3Since the process of pouring powder from the material hopper 7 takes a certain amount of time, multiple receiving mechanisms 3 are set up. These multiple receiving mechanisms 3 can be arranged in parallel, allowing multiple material hoppers 7 to be fed at the same time. The number of adsorption drive sources 52 and adsorbents 51 are matched with the number of receiving mechanisms 3 that can be used simultaneously, so that the lid of each material hopper 7 entering the feeding process can be temporarily stored by the lid pick-and-place assembly 5, realizing multi-station synchronous automated operation and improving the overall production efficiency of aseptic powder feeding.

[0052] In this embodiment, the feeding and docking device 12 has two receiving mechanisms 3, and two adsorption drive sources 52 are also provided. The connecting rod 53 is a long straight rod, and the output shaft of the rotator is connected to the midpoint of the connecting rod 53. The two adsorption drive sources 52 are respectively connected to the lower ends of the connecting rod 53. The adsorption drive source 52 is an adsorption cylinder, and the suction cup is fixedly connected to the end of the piston rod of the adsorption cylinder. The extension and retraction direction of the piston rod of the adsorption cylinder is vertical. When the material barrel 7 is conveyed to the end of the feeding track 41 or the beginning of the discharge track 42, the piston rod of the adsorption cylinder can be coaxial with the material barrel 7.

[0053] Based on the above embodiments, such as Figure 1 , Figures 4-7 As shown, the flipping mechanism 1 is equipped with a movable actuator end, which is fitted with a clamp 2. The clamp 2 can stably clamp and fix the aluminum material bucket 7. The actuator end has multi-dimensional movement and flipping capabilities, and can carry the clamped and fixed material bucket 7 to complete translation, lifting, flipping and other actions.

[0054] In the specific implementation process, the flipping mechanism 1 can be a multi-axis robot. The receiving mechanism 3 includes a support frame 36, and a receiving pipe 31 is fixedly mounted on the support frame 36. The support frame 36 is fixedly mounted on one side of the multi-axis robot. The top of the receiving pipe 31 has a receiving port for material docking and introduction, and the receiving port faces upwards. The bottom of the receiving pipe 31 will be equipped with a dispensing container (not shown in the figure) for batch transfer and storage.

[0055] In actual operation, the opening of the material bucket 7 on the feeding track 41 is originally facing upward. The flipping mechanism 1 clamps the material bucket 7 containing sterile powder through the clamp 2, and drives the material bucket 7 to move from the feeding track 41 to the receiving mechanism 3. Then, the flipping action of the actuator drives the material bucket 7 to flip, so that the opening of the material bucket 7 faces downward and is precisely attached and sealed with the receiving port at the top of the receiving pipe 31.

[0056] like Figure 4 and Figure 5 As shown, the clamp 2 adopts a pneumatic clamping structure, which includes a gripper cylinder 24 and two symmetrically arranged clamping plates 21. The two clamping plates 21 are respectively fixedly connected to the two telescopic ends of the gripper cylinder 24, and can be opened and closed synchronously with the telescopic movement of the gripper cylinder 24.

[0057] Two clamping plates 21 are respectively attached to the outer walls of the two sides of the material barrel 7. The clamping plates 21 are bent to form clamping grooves on the inner side of the material barrel 7. For the cylindrical material barrel 7, the clamping grooves can make the clamping plates 21 and the side walls of the material barrel 7 have more contact points, thereby realizing the centered positioning and stable clamping of the material barrel 7.

[0058] Furthermore, a flexible contact pad 22 is fixedly installed inside the clamping groove. The contact pad 22 is made of food-grade sterile silicone and directly contacts the side wall surface of the material barrel 7. The flexible contact pad 22 can increase the coefficient of friction with the material barrel 7, improve the clamping stability, and at the same time avoid the rigid clamping plate 21 directly squeezing the material barrel 7, causing barrel deformation and surface scratches. It can adapt to material barrels 7 with slight dimensional deviations, improving the equipment's adaptability.

[0059] In one specific implementation, reference is made to... Figure 5 The clamp 2 also includes a sealing valve 23, which is located next to the gripper cylinder 24. While the clamping plate 21 clamps and fixes the material bucket 7, the sealing valve 23 is matched with the material bucket 7. The valve core structure of the sealing valve 23 can be controlled to switch the opening and closing of the material bucket 7. During the transfer and docking of the material bucket 7, the bucket opening is kept closed to prevent external impurities and bacteria from entering the material bucket 7 and contaminating the sterile powder, and also to prevent the powder from spilling during the turning process. After the bucket opening and the receiving port are sealed and docked, the bucket opening is opened by the valve core to allow the material to be discharged, ensuring the sterility and safety of the feeding process.

[0060] Specifically, the sealing valve 23 includes a valve body and a valve plate. When the sealing valve 23 is assembled with the opening of the material tank 7, the end face of the valve body and the end face of the opening of the material tank 7 are coaxially fitted and abutted together to form an annular sealing contact surface. The sealing valve 23 can be a butterfly valve, in which the valve plate is rotatably installed inside the valve body, the rotating shaft of the valve plate passes through the side wall of the valve body, and the operating block 231 is fixedly installed at the outer end of the rotating shaft. The operating block 231 is arranged on the outside of the valve body. Without disassembling the structure, the rotating shaft can be driven to rotate through the operating block 231, thereby driving the valve plate inside the valve body to rotate, realizing the opening and closing switching of the sealing valve 23, which is suitable for aseptic and closed operation scenarios.

[0061] Based on the above embodiments, such as Figure 6As shown, the receiving mechanism 3 is equipped with a valve opener 32. The core structure of the valve opener 32 is the valve opening sleeve 321, which is connected to the support frame 36 and is rotatable. When the opening of the material bucket 7 and the receiving port are sealed together, the valve opening sleeve 321 needs to cooperate with the operating block 231, that is, the valve opening sleeve 321 is exactly fitted outside the operating block 231 on the outside of the valve body. In the specific implementation process, the valve opener 32 also includes a valve opening cylinder 322 and a valve opening motor 323. The cylinder body of the valve opening cylinder 322 is connected to the support frame 36, and its piston rod extends and retracts horizontally. The valve opening motor 323 is connected to the end of the piston rod of the valve opening cylinder 322, and its output shaft axis is horizontal. The valve opening sleeve 321 is coaxially fixedly connected to the end of the output shaft of the valve opening motor 323, so that the valve opening sleeve 321 can move horizontally and rotate around its own axis.

[0062] When the opening of the material hopper 7 is sealed and connected to the receiving port, the rotation axis of the valve opening sleeve 321 coincides with the rotation axis of the operating block 231, and the piston rod of the valve opening cylinder 322 extends, allowing the end of the valve opening sleeve 321 to be fitted over the operating block 231. The projection of the operating block 231 along the axis of rotation of the valve plate is set as a non-circular structure such as square or rhombus, so that a circumferential limiting fit relationship is formed between the valve opening sleeve 321 and the operating block 231, and the inner contour of the valve opening sleeve 321 matches the shape of the operating block 231. After the two are fitted together, the valve opening sleeve 321 rotates, which can drive the operating block 231 to rotate synchronously, indirectly driving the valve plate to rotate and open the sealing valve 23, realizing automated valve opening and feeding. The valve opening and closing process also realizes unmanned operation, further reducing the aseptic risk caused by human intervention.

[0063] Based on any of the above embodiments, such as Figure 6 and Figure 7 As shown, the receiving mechanism 3 also includes a vibrator 33, which consists of a collision body 331 and a vibration source 332. The vibration source 332 is mounted on the support frame 36, and the collision body 331 is fixedly connected to the power output end of the vibration source 332. In specific implementation, the support frame 36 is equipped with a telescopic cylinder 333, and the piston rod of the telescopic cylinder 333 extends and retracts in the radial direction of the receiving port. The vibrator 33 is mounted on the end of the piston rod of the telescopic cylinder 333. The vibrator 33 can be a vibration motor, and the collision body 331 can be a plastic block or a rubber block.

[0064] During the process of sealing and connecting the opening of the material hopper 7 with the receiving port and opening the sealing valve 23 to feed material, the piston rod of the telescopic cylinder 333 extends forward, allowing the impactor 331 to contact the side wall of the material hopper 7. Then, the vibration source 332 is activated, driving the impactor 331 to perform high-frequency reciprocating motion, causing the impactor 331 to continuously and intermittently impact the wall of the material hopper 7. The frequent vibration causes the sterile powder inside the material hopper 7 to loosen and fall, effectively avoiding problems such as powder agglomeration and adhesion to the hopper wall, resulting in feeding residue and improving powder feeding efficiency.

[0065] Based on the above embodiment, a pressure barrel body 34 is movably disposed above the material receiving port on the support frame 36. The support frame 36 is also provided with a reinforcement controller 341, which is an electric telescopic control component or a cylinder, etc., and can control the reciprocating movement of the pressure barrel body 34 towards or away from the material receiving port. In this embodiment, the movement direction of the pressure barrel body 34 is vertical. When the material barrel 7 is inverted and the barrel opening and the material receiving port are sealed and connected, the pressure barrel body 34 is located above the material barrel 7.

[0066] The reinforcement controller 341 drives the pressure barrel body 34 to move downward, so that the bottom surface of the pressure barrel body 34 tightly abuts against the end face of the material barrel 7 away from the material inlet, forming an axial pressing and fixing effect on the material barrel 7. This can effectively counteract the tendency of the material barrel 7 to shift or loosen during the operation of the vibrator 33, and ensure the stability of the sealing connection between the barrel opening and the material inlet.

[0067] In the specific implementation process, the flipping mechanism 1 contains only one multi-axis manipulator and has only one actuator. Since the material in the hopper 7 takes a long time to fall, the clamp 2 and the actuator of the flipping mechanism 1 can be connected by a quick-change plate 11. The clamp 2 and the actuator of the flipping mechanism 1 are respectively fixed with quick-change plates 11, and the quick-change plates 11 of the two can be quickly docked and fixed after contact. A placement platform for placing multiple clamps 2 is also provided next to the flipping mechanism 1.

[0068] Multiple receiving mechanisms 3 can be arranged around a flipping mechanism 1, or multiple parallel receiving pipes 31 can be arranged around the receiving mechanism 3, so that a flipping mechanism 1 can transfer powder to multiple material buckets 7 at the same time. When a material bucket 7 is placed on the receiving mechanism 3 for static unloading, the actuating end of the flipping mechanism 1 can be temporarily separated from the clamp 2 of the material bucket 7. The clamp 2 and the sealing valve 23 remain on the material bucket 7. At this time, the stability of the material bucket 7 is entirely guaranteed by the pressure bucket body 34.

[0069] Based on any of the above embodiments, the support frame 36 is equipped with a closing controller 351 and a movably mounted closing plate 35. The closing controller 351 adopts an electric drive structure, which can precisely control the closing plate 35 to perform translational or flipping movements to achieve the switching of closing and opening of the receiving port. During equipment standby, the early stage of docking with the material tank 7, and the process of the material tank 7 being disengaged after feeding, the closing controller 351 drives the closing plate 35 to cover and block the receiving port, blocking the connection between the receiving pipe 31 and the external space, and preventing external dust and microorganisms from entering the interior of the receiving pipe 31; only when the material tank 7 is about to dock and is ready to feed, the closing plate 35 is driven to move away and open the receiving port.

[0070] Specifically, the closing controller 351 is a motor, which is fixedly installed on the support frame 36 and located next to the receiving port. Its output shaft axis is vertical. The closing plate 35 is fixedly connected to the output shaft of the motor and its surface is horizontal. The closing controller 351 can control the closing plate 35 to rotate horizontally. When the closing plate 35 rotates to above the receiving port, the lower surface of the closing plate 35 contacts the top surface of the receiving pipe 31, thereby achieving a seal at the receiving port.

[0071] Based on any of the above embodiments, such as Figure 1 and Figure 8 As shown, the entire system spans three rooms. The automatic feeding system also includes a sterilization chamber 62, which is one of the rooms. A buffer platform track 621 is installed inside the sterilization chamber 62 to store the sterilization buckets 7 to be fed, achieving buffering and static placement of the materials after sterilization. The buffer platform track 621 has a similar structure to the conveyor track. The feed track 41 extends into the sterilization chamber 62 and connects with the buffer platform track 621. The sterilized buckets 7 can be directly transferred from the buffer platform track 621 to the feed track 41.

[0072] The other two rooms are the operation room 64 and the feeding room 65. The feeding docking device 12, the pick-and-place cover assembly 5, the end of the feeding track 41, and the beginning of the discharge track 42 are all located in the feeding room 65. The operation room 64 is located between the feeding room 65 and the sterilization room 62.

[0073] like Figure 1 and Figure 11 As shown, the end of the discharge track 42 is located outside the sterilization chamber 62. Empty containers that have been filled can be directly transported to the collection area outside the sterilization chamber 62 via the discharge track 42, effectively separating the clean operating area from the external collection area and preventing contamination of the sterile feeding area by the external environment. In specific implementation, the end of the discharge track 42 is located inside the operating room 64, allowing operators to retrieve the empty container 7 that has been moved to the end of the discharge track 42 from within the operating room 64. Figure 1 The right arrow in room 64 of the middle work area and Figure 11 The right arrows in the diagram all point in the direction to remove the empty bucket.

[0074] Based on this, such as Figure 1 and Figure 9 As shown, the feeding track 41 also passes through the working room 64. Inside the working room 64, transparent partitions are installed on both sides of the feeding track 41 to separate the feeding track 41 from the spatial environment inside the working room 64, thereby reducing contamination of the material bucket 7.

[0075] The frame 6 has a manual cap loosening station 61 set up in the working room 64. The manual cap loosening station 61 is arranged on the feeding track 41 and is located between the cap picking and placing assembly 5 and the sterilization chamber 62. An isolation operation plate 66 is fixedly installed on the frame 6 at the manual cap loosening station 61. The isolation operation plate 66 has a special operation hole 661 on its surface, and a sealed operation glove is fixedly installed at the operation hole 661.

[0076] In actual implementation, the lid of the material hopper 7 has two layers: an inner lid and an outer lid. The inner lid and the material hopper 7 are pre-tightened by friction, and the outer lid and the inner lid are detachably connected. The manual lid loosening station 61 is set as a two-person operation station. The first operator can remove the outer lid at the manual lid loosening station 61, and the second operator can then loosen the inner lid without opening the mouth of the material hopper 7, so that the inner lid remains in the state of the mouth of the hopper.

[0077] Based on the above embodiments, such as Figure 1 and Figure 8 As shown, the buffer platform track 621 is set as a multi-layer structure along the vertical height direction, which can buffer and store a large number of sterilization material barrels 7 in layers, thereby increasing the material buffering capacity in a limited space and adapting to continuous uninterrupted production.

[0078] like Figure 10 As shown, the feeding track 41 has only one layer of height. A lifting track platform 63 is installed between the buffer platform track 621 and the feeding track 41. The lifting track platform 63 and the frame 6 form a vertical sliding fit structure. It can be driven by a motor with chain drive to move up and down vertically along the frame 6. By adjusting the height of the lifting track platform 63, the material buckets 7 on the multi-layer buffer platform track 621 can be sequentially connected and transferred to the feeding track 41, realizing the orderly discharge of multi-layer buffered materials.

[0079] In the specific implementation process, such as Figure 10 and Figure 11 As shown, the height of the rear section of the discharge track 42 is reduced, so that the rear half of the discharge track 42 can pass through the bottom of the feed track 41 and be arranged vertically stacked with the feed track 41 to reach the working room 64 together. Therefore, a lifting track platform 63 is also provided in the middle section of the discharge track 42.

[0080] Based on any of the above embodiments, such as Figure 2 As shown, the feeding room 65 is also equipped with an isolation operation panel 66 with an operation hole 661 at the cover picking and placing assembly 5. When the automatic cover picking or placing operation of the cover picking and placing assembly 5 fails or is misoperated, the system will issue an alarm and stop running. Relevant personnel can make timely adjustments here so that the automatic feeding system can continue to operate.
