Description

Technical Field

[0001] This invention relates to the field of filling equipment technology, specifically to an automated filling equipment for storage-type dry powder inhalers. Background Technology

[0002] Dry powder automated filling equipment is an automated packaging equipment designed for powdered materials. It integrates automatic feeding, accurate metering, filling, dust prevention, sealing and finished product conveying into one unit. The entire process is automated and mostly adopts servo screw or weighing metering, which can effectively prevent dust and pollution. Compared with manual labor, the efficiency is significantly improved. It is widely used in industries such as milk powder, pharmaceutical powder, seasoning, and dry powder coatings.

[0003] Before filling the bottles, a robotic arm is needed to clamp and place the bottles on top of the turntable to facilitate sequential filling. However, the filling nozzle of the bottle may not be in the exact center. If the bottle is not placed correctly on top of the turntable, it will cause inaccurate alignment between the filling nozzle of the bottle and the discharge port of the filling component. Therefore, a storage-type automated filling equipment for dry powder inhalers is needed to facilitate accurate alignment of the bottle with the discharge port of the filling component.

[0016] Working principle: When feeding bottles, the robotic arm grabs the bottles from the material tray and places them on top of the placement plate. A camera takes a picture of the bottles to identify whether the placement is correct. If the placement of the bottles is off, the electric push rod moves the moving frame to squeeze the bottles between the positioning wheel and the rotating wheel. The drive motor drives the rotating wheel to rotate through the track, adjusting the angle of the bottles until the position is correct. The robotic arm grabs the corrected bottles and places them into the placement seat on top of the turntable.

The filling component injects dry powder into the bottles to complete the filling.

[0017] When capping bottles, the turntable transports the filled bottles to the bottom of the capping assembly. Personnel stack the caps and place them into the injection tube. Drive motor two drives the lower chassis, injection tube, and upper top chassis to rotate, aligning the injection tube with the feed port of the rotating plate. Drive motor four drives the threaded sleeve to rotate via track two. The lead screw moves down and extends into the inside of the injection tube to squeeze the caps. The lead screw moves down a suitable distance so that a single cap is squeezed out from the discharge port and falls above the feed port of the rotating plate. Drive motor three drives the rotating plate to rotate 180 degrees, transporting the caps directly above the filled bottles. The telescopic cylinder is energized and extends its output shaft to squeeze the caps, squeezing them out from the feed port and pressing them against the bottle mouth, completing the capping process.

[0018] Camera 2 takes pictures of the capped bottles to check whether the sealing is in place. When a defective product is detected, robotic arm 2 picks it up and moves it to the defective product area. When the bottle is a qualified product, robotic arm 2 picks it up and places it in the collection tray. When a single filling tube cap is used up, the filling tube can be switched by drive motor 2. When all filling tube caps are used up, the spare lower base, filling tube and upper plate can be disassembled and replaced to continue the sealing operation and complete the entire filling and capping process.

[0032] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Please see the appendix Figure 1 -Appendix Figure 8This invention provides an automated filling device for dry powder inhalers, comprising a workbench 1, a frame 11 fixedly mounted on the top of the workbench 1, a mounting frame 12 mounted on the top of the frame 11, a support frame 101 fixedly mounted on the top of the mounting frame 12, a drive motor 102 mounted on the top of the support frame 101, the output shaft of the drive motor 102 penetrating into the mounting frame 12 and fitted with a track 103, a rotating rod 104 rotatably mounted inside the mounting frame 12, and a rotating wheel 105 fixedly fitted at the bottom of the rotating rod 104 into the mounting frame 12. One end of track 103, away from drive motor 102, is sleeved on the outer surface of rotating rod 104. A mounting plate 106 is fixedly installed on the top of frame 11, and an electric push rod 107 is mounted on the top of mounting plate 106. A movable frame 108 is fixedly installed on the output shaft of electric push rod 107, and a positioning wheel 109 is mounted on the top of movable frame 108. A placement plate 110 is fixedly installed on the outer wall of frame 11. A support rod 111 is provided on the top of workbench 1, and a camera 112 is fixedly sleeved on the outer surface of support rod 111. A rotating assembly and a sealing assembly are provided on the top of workbench 1. Two rotating wheels 105 and two positioning wheels 109 are provided, symmetrically distributed on both sides of placement plate 110. The camera 112 is located on the top of placement plate 110.

[0034] Specifically, the mounting frame 12 is positioned above the workbench 1 via the frame 11. The drive motor 102 is mounted on top of the mounting frame 12 via the support frame 101, allowing the output shaft of the drive motor 102 to extend through the bottom of the support frame 101. The bottom of the rotating rod 104 is inserted from the top of the mounting frame 12 to the bottom of the mounting frame 12, and the rotating rod 104 is rotatably connected to the mounting frame 12 via bearings. One end of each of the two tracks 103 is offset and mounted on the outer surface of the output shaft of the drive motor 102, while the other ends of the two tracks 103 are respectively mounted on the outer surfaces of the two rotating rods 104. The drive motor 102, after being powered on by the controller, can drive the two rotating rods 104 to rotate together. The rotation of the two rotating rods 104 can drive the two rotating wheels 105, which are fixedly sleeved on the outer surface, to rotate together. The mounting plate 106 is horizontally mounted on the top of the frame 11, and the electric push rod 107 is horizontally mounted on the top of the mounting plate 106. After the controller powers on the electric push rod 107, the extension and retraction of the output shaft of the electric push rod 107 can drive the moving frame 108 to move horizontally. The two positioning wheels 109 are mounted on the top of the moving frame 108 by rotating shafts. The placement plate 11 is then placed on top of the frame 108. The 0 is fixed to the outer wall of the frame 11, and the placement plate 110 is located between the two positioning wheels 109 and the two rotating wheels 105. The bottom of the placement plate 110 is lower than the bottom of the two positioning wheels 109 and the two rotating wheels 105. When the filling bottle is placed on top of the placement plate 110, the camera 112 is mounted above the placement plate 110 with the help of the support rod 111. It can take pictures and identify the filling bottle to determine whether the placement position of the filling bottle is correct. When the placement position of the filling bottle is incorrect, the electric push rod 107 is energized to drive the moving frame 108 to move towards the placement plate 110 and squeeze the filling bottle. The bottle is positioned between the two positioning wheels 109 until the other side of the outer surface of the bottle rests between the two rotating wheels 105. The drive motor 102 is powered on and starts to rotate the two tracks 103. The two tracks 103 drive the two rotating rods 104 and the two rotating wheels 105 to rotate together. The rotating wheels 105 rotate against the outer surface of the bottle, which can drive the bottle to rotate together and change the placement angle. The camera 112 takes pictures in real time to determine that the bottle is always placed correctly, so as to achieve the effect of adjusting the bottle to the predetermined position for feeding. This makes it easy for the filling port on the top of the bottle to connect with the filling component 21 for filling.

[0035] Please see the appendix Figure 1 With appendix Figure 6 A robotic arm 2 is mounted on the top of the workbench 1, and a filling component 21 is mounted on the top of the workbench 1.

[0036] The rotating assembly includes a servo motor 3 installed inside the worktable 1. The output shaft of the servo motor 3 extends through to the top of the worktable 1 and a turntable 31 is installed thereon. A placement seat 32 is fixedly installed on the top of the turntable 31.

[0037] Specifically, robotic arm 2 can grab the filling bottle placed on the top of the material tray and place the filling bottle on the top of the placement plate 110 for correction. After the filling bottle is corrected, robotic arm 2 grabs the corrected filling bottle again and places the corrected filling bottle into the placement seat 32 on the top of the turntable 31. Multiple placement seats 32 are arranged in a circle on the top of the turntable 31. The controller can control the servo motor 3 to drive the turntable 31 to rotate in sections, so as to move the filling bottles in the multiple placement seats 32 to different positions for filling operations. When the turntable 31 moves the corrected filling bottle in the placement seat 32 to below the filling component 21, the filling component 21 can complete the flow of dry powder material and inject the dry powder material into the filling bottle to complete the filling of dry powder material.

[0038] It should be noted that the internal structure connection and installation of the robotic arm 2 and the filling component 21 are existing technologies, and their working principle is common knowledge to those skilled in the art, and will not be elaborated here.

[0039] Please see the appendix Figure 6 -Appendix Figure 8 The sealing assembly includes a second drive motor 4 and a third drive motor 41 installed inside the workbench 1. A fixed sleeve 44 is fixedly installed on the top of the workbench 1. A fixed plate 42 is fixedly sleeved on the top of the outer surface of the fixed sleeve 44. The top of the output shaft of the second drive motor 4 passes through the workbench 1 and is inserted into the inside of the fixed sleeve 44. A feeding assembly is installed on the top of the fixed plate 42. A rotating plate 43 is installed on the top of the output shaft of the third drive motor 41.

[0040] The feeding assembly includes a lower chassis 5 and an upper top chassis 51. The top of the lower chassis 5 is equipped with multiple injection pipes 52 arranged in a circumferential array. The upper top chassis 51 has multiple feed inlets 53 arranged in a circumferential array inside. The lower chassis 5 has multiple discharge outlets 54 arranged in a circumferential array inside. The tops of the injection pipes 52 are installed at the bottom of the upper top chassis 51. The tops of the multiple injection pipes 52 correspond one-to-one with the bottoms of the multiple feed inlets 53, and the bottoms of the multiple injection pipes 52 correspond one-to-one with the tops of the multiple discharge outlets 54.

[0041] The upper plate 51 has a threaded post 6 inside, and the bottom of the threaded post 6 is threaded inside the lower plate 5. The top of the rotating plate 43 has two symmetrically distributed discharge ports 7, and the rotating plate 43 is located at the bottom of the lower plate 5.

[0042] A fixed rod 8 is fixedly installed on the top of the workbench 1. A fixed frame 81 is fixedly installed on the top of the fixed rod 8. A support frame 82 is fixedly installed on the bottom of the inner wall of the fixed frame 81. A drive motor 83 is installed on the top of the support frame 82. The output shaft of the drive motor 83 passes through the bottom of the support frame 82 and is sleeved with a track 84. A threaded sleeve 85 is sleeved on the end of the track 84 away from the drive motor 83. A lead screw 86 is connected to the internal thread of the threaded sleeve 85. A connecting frame 87 is installed on the outer wall of the fixed frame 81. A telescopic cylinder 88 is installed at the bottom of the connecting frame 87.

[0043] The threaded sleeve 85 is rotatably mounted on the bottom of the inner wall of the fixed frame 81, and the bottom of the lead screw 86 passes through the bottom of the fixed frame 81 and extends into the inlet 53 and the inside of the injection pipe 52.

[0044] Specifically, drive motor 4 is installed in a fixed position inside the worktable 1. The output shaft of drive motor 4 is connected to a shaft rod. The top of the shaft rod passes through the worktable 1 and is inserted into the interior of the fixed sleeve 44. The top of the shaft rod extends out to the outside of the fixed sleeve 44 and is threadedly connected to the bottom of the lower base plate 5. The lower base plate 5 and the upper top plate 51 are respectively installed at the bottom and top of multiple injection tubes 52. The bottom of the threaded column 6 passes through the middle thread of the upper top plate 51 and is threadedly connected to the interior of the lower base plate 5. The multiple injection tubes 52 are circumferentially distributed and limited between the lower base plate 5 and the upper top plate 51. The bottom and top of the multiple injection tubes 52 are respectively connected to the lower base plate 5. Multiple discharge ports 54 and multiple inlets 53 of the upper top plate 51 are connected one by one. After the controller powers on the second drive motor 4, it can drive the lower base plate 5, multiple injection pipes 52 and the upper top plate 51 to rotate on the top of the fixed plate 42. Personnel can stack the can lids from the inlets 53 into the inside of the multiple injection pipes 52 to complete the filling of the can lids. By twisting the lower base plate 5, the lower base plate 5, multiple injection pipes 52 and the upper top plate 51 can be removed from the top of the output shaft of the second drive motor 4, so that the lower base plate 5, multiple injection pipes 52 and the upper top plate 51 can be replaced after the can lids are used in the multiple injection pipes 52.

[0045] The drive motor 3 41 is also installed in a fixed position inside the workbench 1. The drive motor 3 41 is fixedly connected to the bottom of the rotating plate 43 via a shaft. The controller can control the drive motor 3 41 to drive the rotating plate 43 to rotate 180 degrees intermittently. The discharge port 7 at one end of the rotating plate 43 is located at the bottom of the discharge port 54 of the lower base 5. The discharge port 7 at the other end of the rotating plate 43 is located above the placement seat 32. A notch is provided on the side of the rotating plate 43 that contacts the fixed plate 42. Thus, the rotating plate 43 can be rotated to the bottom of the lower base 5 by the drive motor 3 41 to catch the can cap falling from the discharge port 54. When the filling bottle is placed inside the placement seat 32, the discharge port 7 is exactly above the filling port of the filling bottle.

[0046] The fixed frame 81 is mounted above the worktable 1 by means of the fixed rod 8. The drive motor 83 is mounted on the top of the support frame 82 at the bottom of the inner wall of the fixed frame 81, so that the output shaft of the drive motor 83 can pass through the hollow position at the bottom of the support frame 82. The output shaft of the drive motor 83 is connected to the threaded sleeve 85 rotatably mounted at the bottom of the inner wall of the fixed frame 81 through the crawler 84. The lead screw 86 is threaded into the inside of the threaded sleeve 85. The controller powers on the drive motor 83 to drive the crawler 84 and the threaded sleeve 85 to rotate together, which allows the lead screw 86 to move up and down inside the threaded sleeve 85. The bottom of the lead screw 86 is connected to the feed at the top. Inside the inlet 53 and the filling tube 52, when the screw 86 moves downward, it can squeeze the can cap placed inside the filling tube 52, squeezing the can cap from the outlet 54 of the lower base plate 5 to above the discharge port 7 of the rotating plate 43. The discharge port 7 is slightly smaller than the can cap. The controller powers the drive motor 3 41 to rotate the rotating plate 43 180 degrees, rotating the can cap above the filling bottle. The controller controls the output shaft of the telescopic cylinder 88 to extend downward, squeezing the can cap out from the discharge port 7, so that the can cap can close the filling port at the top of the filling bottle, achieving the effect of sealing the filling bottle. Repeating the above steps can continuously seal the filling bottle.

[0047] It should be noted that personnel can stack multiple can caps inside the filling tube 52. When the can caps inside one filling tube 52 are used up, the drive motor 4 83 is energized and reversed to move the lead screw 86 out of the filling tube 52 and the upper plate 51. Then, the drive motor 2 4 rotates the lower plate 5 to move the next filling tube 52 to the top of the rotating plate 43. The drive motor 4 83 then moves the lead screw 86 to re-insert it into the next filling tube 52 to continue dispensing can caps. When the can caps inside multiple filling tubes 52 are used up, personnel can disassemble the lower plate 5, multiple filling tubes 52 and the upper plate 51, and then install a spare lower plate 5, multiple filling tubes 52 and the upper plate 51 to continue dispensing can caps, sealing and filling bottles.

[0048] Please see the appendix Figure 1 A robotic arm 2 9 is installed on the top of the workbench 1, and a support rod 2 91 is installed on the top of the workbench 1. A camera 2 92 is fixedly sleeved on the outer surface of the support rod 2 91.

[0049] Specifically, camera 292 is mounted above workbench 1 with the help of support rod 291. It can take pictures and identify the capped bottles to determine whether the bottles are properly sealed. If a bottle is found to be improperly capped, robotic arm 29 can receive the signal to pick up the defective bottle and place it in the defective product area. For qualified bottles, robotic arm 29 can pick them up and place them in the collection tray, thus achieving the effect of filling the bottles.

[0050] Working principle:

[0051] When feeding the bottles, robotic arm 2 grabs the bottles from the material tray and places them on top of the placement plate 110. Camera 112 takes pictures of the bottles to identify whether the placement is correct. If the placement of the bottles is off, electric push rod 107 moves the moving frame 108 to squeeze the bottles between the positioning wheel 109 and the rotating wheel 105. Drive motor 102 drives the rotating wheel 105 to rotate through the track 103 to adjust the angle of the bottles until the position is correct. Robotic arm 2 grabs the corrected bottles and places them into the placement seat 32 on top of the turntable 31. Servo motor 3 drives the turntable 31 to rotate in sections, conveying the bottles to the bottom of the filling component 21. The filling component 21 injects dry powder into the bottles to complete the filling.

[0052] When capping the filled bottles, the turntable 31 transports the filled bottles to the bottom of the capping assembly. The personnel stack the caps and place them into the injection tube 52. The second drive motor 4 drives the lower chassis 5, the injection tube 52 and the upper top plate 51 to rotate, so that the injection tube 52 is aligned with the discharge port 7 of the rotating plate 43. The fourth drive motor 83 drives the threaded sleeve 85 to rotate through the second track 84. The lead screw 86 moves down and extends into the inside of the injection tube 52 to squeeze the cap. The lead screw 86 moves down a suitable distance so that a single cap is squeezed out from the discharge port 54 and falls above the discharge port 7 of the rotating plate 43. The third drive motor 41 drives the rotating plate 43 to rotate 180 degrees, transporting the cap to the top of the filled bottle. The telescopic cylinder 88 is energized and starts to extend the output shaft to squeeze the cap, squeezing the cap out from the discharge port 7 and pressing it onto the bottle mouth to complete the capping.

[0053] Camera 292 takes pictures of the capped bottles to check whether the sealing is in place. When a defective product is detected, robotic arm 29 picks it up and moves it to the defective product area. When the bottle is a qualified product, robotic arm 29 picks it up and places it in the collection tray. When a single filling tube 52 cap is used up, the filling tube 52 can be switched by drive motor 24. When all filling tubes 52 caps are used up, the spare lower base plate 5, filling tube 52 and upper top plate 51 can be disassembled and replaced to continue the sealing operation and complete the entire filling and capping process.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
