Description

Technical Field

[0001] This invention belongs to the field of capsule filling technology, and specifically relates to a capsule filling and packaging machine. Background Technology

[0002] Capsules are widely used as a common medication in the treatment of diseases. A capsule mainly consists of a cap with a larger diameter and a body with a smaller diameter. The inner wall of the cap is tightly fitted with the outer wall of the body to form a complete capsule, which is used to fill the cavity with medicinal powder. A capsule filling and packaging machine is used to fill the cavity with medicinal powder.

[0003] The capsule filling process mainly involves several steps, including directional loading of capsules, separation of capsule body and cap, misalignment of capsule body and cap, metering and filling, removal of waste capsules, closure of capsule body and cap, and unloading. After unloading, the inner cavity of the capsule-bearing area is cleaned by blowing. The separation of capsule body and cap is often achieved using vacuum suction, also known as capsule removal. However, for interlocking capsules (capsule interfaces with interlocking structures), the static friction between the cap and body is significant. Relying solely on vacuum suction often results in capsules not being separated, preventing them from being filled in the next stage. This necessitates the removal of waste capsules during the filling process, leading to capsule waste and reduced production costs. Summary of the Invention

[0004] The purpose of this invention is to provide a capsule filling and packaging machine with a simple structure and reasonable design in order to solve the above problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] A capsule filling and packaging machine, comprising:

[0007] A central turntable, along its rotation direction, has a feeding mechanism, a replenishment mechanism, a filling mechanism, a closing mechanism, a discharging mechanism, and a cleaning mechanism arranged sequentially around its periphery. Multiple capsules are evenly distributed along the periphery of the central turntable. Each capsule includes an upper capsule plate and a lower capsule plate. The upper capsule plate holds the capsule cap, and the lower capsule plate holds the capsule body. The replenishment mechanism includes a capsule body separation detection component and a separation component. The capsule body separation detection component detects the separation status of the capsules in the capsules moved to the replenishment station, and the separation component separates any capsules that have not yet separated.

[0008] As a further optimization of the present invention, the upper and lower bladder plates located at the replacement station are sealed and abutted together.

[0009] As a further optimization of the present invention, the lower capsule plate is provided with multiple capsule holes and multiple stepped holes, the capsule holes and stepped holes are corresponding and communicating with each other, and the capsule holes are located above the stepped holes. The diameter of the capsule holes is larger than the diameter of the stepped holes. The capsule separation detection component includes a support plate and a pressure sensor. A support plate is fixedly installed in each capsule hole. The side of the support plate away from the stepped hole has a concave arc support surface, and the radius of the concave arc support surface is consistent with the radius of the convex arc surface of the capsule. A pressure sensor is embedded in the edge of the concave arc support surface of the support plate.

[0010] As a further optimization of the present invention, the separation component includes a transposition component and a pull-down component. The transposition component is disposed in the upper capsule plate, and the pull-down component is disposed in the lower capsule plate. The transposition component is used to clamp and rotate the capsule cap of the unseparated capsule in a circumferential direction, and the pull-down component is used to apply a traction force to the capsule body of the unseparated capsule in a direction away from the capsule cap.

[0011] As a further optimization of the present invention, the indexing assembly includes a rotating cylinder, an indexing seat, a motor, and a third shifting drive. The rotating cylinder is rotatably mounted in the upper bladder plate. A flange is provided on the lower edge of the inner wall of the rotating cylinder. The bladder cap is located in the cavity of the rotating cylinder and overlaps the flange. The output end of the third shifting drive is drivenly connected to a support frame. Multiple motors are provided on the support frame, and the motors are correspondingly arranged with the rotating cylinder. The output end of the motor is drivenly connected to the indexing seat. A locking pin is provided at the lower end of the indexing seat. A locking groove is opened on the rotating cylinder, and the locking pin is correspondingly arranged with the locking groove. An abutment pad is also provided at the lower end of the indexing seat. The abutment pad is used to abut and fix the bladder cap to be rotated.

[0012] As a further optimization of the present invention, the lowering assembly includes a fourth shifting drive, an upper bracket, a lower bracket, a conveyor belt, and an airbag. The output end of the fourth shifting drive is driven by a bracket. The upper bracket and the lower bracket are rotatably connected to the bracket, and the input end of the lower bracket is driven by a motor. The upper bracket and the lower bracket are driven by a conveyor belt. Airbags are evenly arranged on the conveyor belt. When the capsule is not separated, the airbags rub against the side wall of the capsule body under the drive of the fourth shifting drive.

[0013] As a further optimization of the present invention, baffles are provided on both axial sides of the upper bracket, the baffles are fixedly mounted on the support, and a compression plate is fixedly mounted on the baffle. The side of the compression plate facing the airbag is a vertical plane, and the length of the vertical plane of the compression plate is greater than the distance between the two airbags.

[0014] As a further optimization of the present invention, the airbag protrudes symmetrically on both sides of the conveyor belt in the initial state.

[0015] As a further optimization of the present invention, the lower bracket has a waist-drum shaped structure.

[0016] As a further optimization of the present invention, the lower bladder plate is fixedly disposed at the output end of the second displacement driving member, the second displacement driving member is disposed at the output end of the first displacement driving member, the first displacement driving member is disposed on the central turntable, the first displacement driving member is used to drive the second displacement driving member to reciprocate along the radial direction of the central turntable, and the second displacement driving member is used to drive the lower bladder plate to reciprocate along the vertical direction.

[0017] The present invention has at least the following beneficial effects: The capsule filling and packaging machine provided by the present invention includes a central turntable. Along the rotation direction of the central turntable, a feeding mechanism, a replenishing mechanism, a filling mechanism, a closing mechanism, a discharging mechanism, and a cleaning mechanism are sequentially arranged on the periphery of the central turntable. Multiple capsules are evenly distributed along the periphery of the central turntable. Each capsule includes an upper capsule plate and a lower capsule plate. The upper capsule plate is used to place the capsule cap, and the lower capsule plate is used to place the capsule body. The replenishing mechanism includes a capsule body separation detection component and a separation component. The capsule body separation detection component is used to detect the separation status of the capsules in the capsules moved to the replenishing station. The separation component is used to separate the unseparated capsules to achieve the synergistic effect of the rotation of the capsule cap and the downward pull of the capsule body, reduce the static friction between the capsule cap and the capsule body, ensure that all capsules are separated, avoid waste capsules, reduce ineffective filling of drugs, save raw materials, and reduce costs.

[0018] Furthermore, when the airbag in the separation assembly pulls the bladder downwards, the airbag is first squeezed by the upper bracket, causing it to bulge towards the side away from the upper bracket, thereby increasing the frictional contact force on the bladder. Moreover, the lower bracket is provided with a waist drum shape, so that when the conveyor belt passes around the lower bracket, the airbag will not be squeezed by the lower bracket. That is, it is ensured that the airbag only bulges and is compressed when it comes into contact with the bladder, thus ensuring the service life of the airbag. Attached Figure Description

Detailed Implementation

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a capsule filling and packaging machine, comprising:

[0033] A central turntable 7 has a feeding mechanism 1, a replenishment mechanism 2, a filling mechanism 3, a closing mechanism 4, a discharging mechanism 5, and a cleaning mechanism 6 arranged sequentially around its periphery. Multiple capsules are evenly distributed around the central turntable 7. Each capsule includes an upper capsule plate 71 and a lower capsule plate 72. The upper capsule plate 71 holds the capsule cap 81, and the lower capsule plate 72 holds the capsule body 82. The replenishment mechanism 2 includes a capsule separation detection component and a separation component. The capsule separation detection component detects the separation status of capsules moved to the replenishment station, and the separation component separates any unseparated capsules.

[0034] The capsules are placed into the capsule container in an orderly manner by the feeding mechanism 1, and the capsules are separated by vacuum pumping. If all the capsules are separated, that is, the capsule separation detection component detects that the separation status of the capsules is yes, then no separation component needs to operate. If the capsule separation detection component detects that the separation status of some capsules is no, then the separation component is activated to separate the corresponding capsules. This ensures that all the capsules on the container can be separated and filled with powder before filling, instead of removing waste capsules before closing. This ensures that 100% of the capsules are filled and avoids the waste of medicine filling at the corresponding waste capsule position in the case of waste capsules.

[0035] It should be noted that the feeding mechanism 1, filling mechanism 3, closing mechanism 4, unloading mechanism 5, and cleaning mechanism 6 mentioned in this application are all prior art, combined with the appendix Figure 2The feeding mechanism 1 is located on one side of the feeding station ①. For example, the feeding mechanism 1 includes a conveying seat, a conveying trough, and a lower pressure plate. It orderly conveys capsules in a uniform direction (i.e., along the conveying direction, with the capsule body 82 located in front of the capsule cap 81) into the conveying trough. When the cleaned capsules are moved to the outlet of the conveying trough, the lower pressure plate presses the capsules into the corresponding capsule seat grooves of the upper capsule plate 71. A vacuum extraction method is used to separate the capsules, so that the capsule body 82 is located in the lower capsule plate 72, and the capsule cap 81 is located in the upper capsule plate 71. The filling mechanism 3 is located on one side of the filling station ④. At this time, the upper capsule plate 71 and the lower capsule plate 72 have been separated. The filling mechanism 3 is used to fill the capsules with the contents of the upper capsule plate 71. The powder is quantitatively injected into the capsule body 82. For example, common filling methods include screw filling and plunger filling. Screw filling uses the rotation of a screw to push the powder into the capsule body 82, and the filling amount can be controlled by adjusting the screw's rotation speed and rotation time. Plunger filling utilizes the reciprocating motion of a plunger to quantitatively fill the capsule body 82 with powder, offering relatively high filling accuracy. The closing mechanism 4 is used to close the powder-filled capsule body 82 with the capsule cap 81. The closing mechanism 4 is located on one side of the closing position ⑧. At this time, the upper capsule plate 71 and the lower capsule plate 72 have re-aggregated together. For example, the closing mechanism 4 includes an upper pressing plate and a lower pressing plate. When the upper capsule plate 71 and lower capsule plate 72, which are joined together, move to the space between the upper pressing plate and the lower abutment post, the abutment drive drives the lower abutment post to move upward. This pushes the capsule body 82, which is filled with medicine powder, upward, so that the capsule body 82 and the capsule cap 81 are tightly pressed together, completing the capsule filling and packaging. The unloading mechanism 5 pushes the capsules filled with medicine powder out of the capsule for collection. The unloading mechanism 5 is located on one side of the unloading station ⑨. For example, the unloading mechanism 5 includes a top rod and a sliding groove. When the capsule moves with the capsule to above the top rod, the top rod passes through the capsule, pushing the capsule out. Under the action of gravity, the capsule falls into the collection box or collection conveyor along the sliding groove. The feeding mechanism 6 is used to blow air through the capsules. The cleaning mechanism 6 is located on one side of the cleaning station ⑩. For example, the cleaning mechanism 6 uses airflow to blow air into the capsules through a high-pressure gas nozzle to blow out residual powder. Some may also be combined with cleaning tools such as brushes to mechanically clean some hard-to-reach areas to ensure the cleanliness of the equipment and clean up any powder that has fallen into the capsules, ensuring that the capsules are clean when they are refilled. Those skilled in the art know the specific structure and working principle of the feeding mechanism 1, filling mechanism 3, closing mechanism 4, unloading mechanism 5 and cleaning mechanism 6, which will not be described in detail here.

[0036] like Figure 2 As shown, each rotation of the central turntable 7 moves the capsule one station, where, as... Figure 2As shown, the central turntable 7 rotates clockwise. Position ① corresponds to the loading station, position ② corresponds to the supplementary position, position ③ corresponds to the separation station, position ④ corresponds to the filling station, position ⑤ corresponds to the transition station (the capsule remains unchanged from ④ to ⑤), position ⑥ corresponds to the horizontal reset station (at this time, the lower capsule plate 72 resets to below the upper capsule plate 71), and position ⑦ corresponds to the vertical reset station (at this time, the lower capsule plate 72 re-abuts against the upper capsule plate 71). For further examples, please refer to the following documentation. Figure 2 , Figure 3 and Figure 4 The lower bladder plate 72 is fixedly disposed at the output end of the second shift drive 722, which is disposed at the output end of the first shift drive 721. The first shift drive 721 is disposed on the central turntable 7. The first shift drive 721 is used to drive the second shift drive 722 to move horizontally and reciprocally along the radial direction of the central turntable 7. The second shift drive 722 is used to drive the lower bladder plate 72 to move reciprocally along the vertical direction. Position ⑧ corresponds to the closing station, position ⑨ corresponds to the unloading station, and position ⑩ corresponds to the cleaning station.

[0037] It should be noted that the upper capsule plate 71, the lower capsule plate 72, the first shifting drive member 721, and the second shifting drive member 722 are arranged in a group, that is, in this application Figure 2The diagram shows 10 workstations, meaning there are 10 sets of upper and lower pouch plates and driving components, consistent with the number of workstations. Under the rotation of the central turntable 7, the upper and lower pouch plates and driving components sequentially pass through positions ① to ⑩. Specifically, the central turntable 7 rotates clockwise, targeting one of the pouches. When the pouch moves to position ①, the upper pouch plate 71 and lower pouch plate 72 abut, and the first and second shifting driving components 721 and 722 are both in their initial positions. When it moves to position ②, the positions of the upper pouch plate 71, lower pouch plate 72, first shifting driving component 721, and second shifting driving component 722 relative to the central turntable remain unchanged. During the movement to position ③, the second shifting driving component 722 drives first, causing the lower pouch plate 72 to move downwards, vertically separating the upper and lower pouch plates 71 and 72. Then, the driving end of the first shifting driving component 721 extends outwards, causing the lower pouch plate 72 to move horizontally away from the central turntable 7. The upper capsule plate 71 and the lower capsule plate 72 are horizontally misaligned. At position ④, the misaligned lower capsule plate 72 exposes the capsule body 82 to the outlet of the injection powder for drug filling. At position ⑤, the positions of the upper capsule plate 71, lower capsule plate 72, first shifting drive 721, and second shifting drive 722 relative to the central turntable remain unchanged. During the shift to position ⑥, the first shifting drive 721 first performs a reset movement, causing the lower capsule plate 72 to move towards the central turntable 7 and directly below the upper capsule plate 71. During the shift to position ⑦, the second shifting drive 722 performs a reset movement again, causing the lower capsule plate 72 to move upwards to abut against the upper capsule plate 71. During the sequential shift to positions ⑧, ⑨, and ⑩, the positions of the upper capsule plate 71, lower capsule plate 72, first shifting drive 721, and second shifting drive 722 relative to the central turntable remain unchanged. When shifting back to position ①, the above actions can be repeated.

[0038] For example, the first shifting drive 721 is an electric telescopic cylinder or a hydraulic telescopic cylinder, which is not limited here, and the second shifting drive 722 is an electric telescopic cylinder or a hydraulic telescopic cylinder, which is not limited here.

[0039] For example, see [link to relevant documentation]. Figure 4 , Figure 5 and Figure 6The lower capsule plate 72 has multiple capsule holes 724 and multiple stepped holes 723. The capsule holes 724 and stepped holes 723 are connected and correspond to each other. The capsule holes 724 are located above the stepped holes 723. The diameter of the capsule holes 724 is larger than that of the stepped holes 723. The capsule separation detection component includes a support plate 725 and a pressure sensor 726. A support plate 725 is fixedly installed in each capsule hole 724. The side of the support plate 725 away from the stepped hole 723 has an arc concave support surface. The radius of the arc concave support surface is the same as the radius of the arc convex surface of the capsule body 82. The pressure sensor 726 is embedded in the edge of the arc concave support surface of the support plate 725. After the capsules are loaded and separated at the loading station, the separated capsules 82 will fall onto the tray 725 under gravity. At this time, the pressure sensor 726 is squeezed, that is, the pressure sensor 726 detects the signal of the separation of the capsule 82, and the separation component does not need to perform the separation operation. If the pressure sensor 726 does not sense the pressure signal when the capsule leaves the loading station ① to the replacement station ②, it means that the capsule at that position has not been successfully separated, and the separation component needs to perform the separation operation on the capsule.

[0040] It should be noted that the stepped hole 723 is used to connect the air extraction port of the vacuum device so that when vacuuming, the vacuum is drawn into the capsule hole 724 through the stepped hole 723. Also, when the closing mechanism 4 is performing the closing operation, the push rod in the closing mechanism 4 passes through the stepped hole 723 to push the capsule body 82 filled with medicine powder in the capsule hole 724 into the capsule cap 81 to complete the closure.

[0041] For example, see [link to relevant documentation]. Figure 4 and Figure 5 The upper capsule plate 71 and the lower capsule plate 72 located at the filling station are sealed and abutted together. By embedding sealing rings on the facing end faces of the upper capsule plate 71 and the lower capsule plate 72 respectively, when the two abut, the abutting surface of the upper capsule plate 71 and the lower capsule plate 72 is sealed and leak-proof when the capsule is vacuumed and separated, thus ensuring the vacuuming force on the capsule body 82.

[0042] For example, see [link to relevant documentation]. Figure 4 and Figure 5 The separation assembly includes a rotation component and a pull-down component. The rotation component is disposed in the upper capsule plate 71, and the pull-down component is disposed in the lower capsule plate 72. The rotation component is used to clamp and rotate the capsule cap 81 of the unseparated capsule. The pull-down component is used to apply a traction force to the capsule body 82 of the unseparated capsule in a direction away from the capsule cap 81. Through the circumferential rotation of the capsule cap 81 and the pull-down of the capsule body 82, the coordinated action of rotation and pull-down breaks the static friction between the capsule cap 81 and the capsule body 82, reduces the separation resistance, and overcomes the biting resistance between the capsule cap 81 and the capsule body 82, allowing the capsule body 82 to be smoothly pulled down to separate the capsule cap 81.

[0043] For example, see [link to relevant documentation]. Figure 4 , Figure 5 , Figure 7 and Figure 8 The indexing assembly includes a rotating cylinder 711, an indexing seat 715, a motor 75, and a third shifting drive 73. The rotating cylinder 711 is rotatably mounted in the upper bladder plate 71. A flange is provided on the lower edge of the inner wall of the rotating cylinder 711. The bladder cap 81 is located in the cavity of the rotating cylinder 711 and overlaps the flange. The output end of the third shifting drive 73 is drivenly connected to a support frame 74. Multiple motors 75 are provided on the support frame 74. The motors 75 are correspondingly arranged with the rotating cylinder 711. The output end of the motors 75 is drivenly connected to the indexing seat 715. A locking post 713 is provided at the lower end of the indexing seat 715. A locking groove 712 is provided on the rotating cylinder 711. The locking post 713 is correspondingly arranged with the locking groove 712. An abutment pad 714 is also provided at the lower end of the indexing seat 715. The abutment pad 714 is used to abut and fix the bladder cap 81 to be rotated.

[0044] When the pressure sensor 726 detects that the capsule has not separated, the third shifting drive 73 is activated. For example, the third shifting drive 73 is a hydraulic telescopic cylinder or an electric telescopic cylinder, which is not limited here. The locking pin 713 is locked in the locking groove 712, and the abutment pad 714 abuts against the arcuate convex surface of the capsule cap 81, so that the capsule cap 81 is fixed in the rotating cylinder 711. The motor 75 drives the rotating seat 715 to rotate, and the rotating seat 715 drives the rotating cylinder 711 to rotate through the locking pin 713, so as to realize the rotation of the capsule cap 81.

[0045] like Figure 8 and Figure 9 As shown, the lowering assembly includes a fourth shifting drive 727, an upper bracket 729, a lower bracket 733, a conveyor belt 732, and an airbag 731. The output end of the fourth shifting drive 727 is drivenly connected to a bracket 728. The upper bracket 729 and lower bracket 733 are rotatably connected to the bracket 728, and the input end of the lower bracket 733 is drivenly connected to a motor. The upper bracket 729 and lower bracket 733 are connected via the conveyor belt 732, on which airbags 731 are evenly distributed. When the capsule is not separated, under the drive of the fourth shifting drive 727, the airbags 731 rub against the side wall of the capsule body 82. Before the motor 75 starts, the fourth shifting drive 727 is first started to drive the bracket 728 to move towards the capsule body 82 until the airbags 731 abut against the capsule body 82. Then, simultaneously with starting the motor 75, the motor is also started, causing the conveyor belt 732 to rotate. Figure 9As shown, the conveyor belt 732 rotates clockwise, and the airbags 731 are abutted against the airbag body 82 one by one, dragging the airbag body 82 downward to realize the downward pulling operation of the airbag body 82. Similarly, the conveyor belt 732, which is symmetrically arranged on the other side of the airbag body 82, rotates counterclockwise to realize multi-point abutment and downward dragging of the airbag body 82.

[0046] For example, see [link to relevant documentation]. Figure 9 and Figure 11 The upper bracket 729 has baffles 734 on both axial sides, which are fixedly mounted on the support 728. A compression plate 730 is fixedly mounted on the baffles 734. The side of the compression plate 730 facing the bladder 82 is vertical, and the length of the vertical surface of the compression plate 730 is greater than the distance between the two airbags 731. This ensures that at least two airbags 731 simultaneously abut against the bladder 82, increasing the downward pulling friction force on the bladder 82.

[0047] For example, see [link to relevant documentation]. Figure 9 In its initial state, the airbag 731 protrudes symmetrically on both sides of the conveyor belt 732. When the conveyor belt 732 is rotated around the upper bracket 729, the side of the airbag facing the upper bracket 729 is compressed, causing the airbag 731 to bulge completely away from the upper bracket 729. This increases the contact force between the airbag 731 and the bladder body 82. When the airbag 731 rotates away from the compression plate 730, it returns to its initial state as the compression stops.

[0048] The lower support 733 has a waist-drum shaped structure, so that when the conveyor belt 732 rotates around the lower support 733, the waist-drum area of ​​the waist-drum shaped structure is used to make way for the airbag 731, so as to avoid additional compression and deformation of the airbag 731 which is not in the position of abutting against the airbag body 82, thus ensuring the service life of the airbag 731.

[0049] It should be noted that, during use, the central turntable 7 of this capsule filling and packaging machine rotates, causing the capsules to pass through the feeding station, the replenishment station, the separation station, the filling station, the transition station, the horizontal reset station, the vertical reset station, the closing station, the unloading station, and the cleaning station in sequence to complete the complete filling and packaging of the capsules. If there are capsules that have not been separated after the capsules are rotated to the replenishment station, the corresponding tray 725 will not support the capsule body 82. At this time, the pressure sensor 726 will not be squeezed by the capsule body 82. The third shift drive 73 will start the operation based on the signal that the pressure sensor 726 is not squeezed by the capsule body 82, move the support frame 74 down to the locking post 713 and engage with the locking slot 712, and the abutment pad 714 abuts against and fixes the capsule cap 81. The fourth shift drive 727 will be activated, and the bracket 728 will move to the right, so that the air bag 731 rubs against the capsule body 82.

[0050] The motor 75 is started, causing the indexing seat 715 to drive the rotating drum 711 to rotate. The capsule cap 81 rotates with the rotating drum 711. At the same time, the motor is started, and the lower support 733 rotates, driving the conveyor belt 732 to rotate. This causes multiple airbags 731 to sequentially abut against the capsule body 82 and move downwards. This achieves the synergistic effect of the capsule cap 81 rotating and the capsule body 82 moving downwards, which helps the capsule cap 81 and capsule body 82 to separate smoothly. This ensures that each capsule body 82 is filled with medicine during subsequent drug filling, avoiding waste capsules and ineffective drug filling, and saving raw materials.

[0051] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
