DETAILED DESCRIPTION

[0031] It is necessary to point out here that the following detailed description is only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application, and the skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0032] As shown in Figure 1 , Figure 2 and Figure 3 , the present application provides a capsule filling and packaging machine, which comprises:

[0033] The center rotating disc 7 is provided with the feeding mechanism 1, the make-up mechanism 2, the filling mechanism 3, the closing mechanism 4, the discharging mechanism 5 and the cleaning mechanism 6 in sequence along the circumferential side of the center rotating disc 7 in the rotating direction of the center rotating disc 7, and a plurality of capsule fixtures are uniformly distributed and arranged along the circumferential side of the center rotating disc 7, wherein the capsule fixture comprises an upper capsule plate 71 and a lower capsule plate 72, the upper capsule plate 71 is used for placing a capsule cap 81 of a capsule, and the lower capsule plate 72 is used for placing a capsule body 82 of the capsule, the make-up mechanism 2 comprises a capsule separation detection assembly and a separation assembly, the capsule separation detection assembly is used for detecting the separation state of the capsule in the capsule fixture shifted to the make-up station, and the separation assembly is used for separating the capsule which is not separated.

[0034] The capsule is sequentially placed in the capsule fixture through the feeding mechanism 1, and the capsule is separated by means of the vacuum air extraction method, if the capsules are all separated, that is, the capsule separation detection assembly detects that the separation state of the capsule is yes, the separation assembly does not need to work, if the capsule separation detection assembly detects that the separation state of part of the capsules is no, the separation assembly is started to separate the corresponding capsules, so that the capsules on the capsule fixture can be completely separated for filling of the medicine powder before filling, instead of removing the waste capsules before closing, so that the capsules are 100% filled, and the waste capsule situation is avoided, and the waste medicine filling situation at the position corresponding to the waste capsule is avoided.

[0035] It should be noted that the feeding mechanism 1, the filling mechanism 3, the closing mechanism 4, the discharging mechanism 5 and the cleaning mechanism 6 mentioned in the present application are all prior art, and the specific structure and working principle thereof are not described in detail. Figure 2The feeding mechanism 1 is arranged on one side of the feeding station 1, and the feeding mechanism 1 includes a conveying seat, a feeding groove and a lower pressing plate. The capsules are sequentially conveyed in a unified direction (i.e., along the conveying direction, the capsule body 82 is located in front of the capsule cap 81) into the feeding groove, and when the cleaned capsule is displaced to the outlet of the feeding groove, the lower pressing plate is used to press the capsule into the capsule seat groove of the upper capsule plate 71, and the vacuum suction method is used to separate the capsule, 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 arranged on one side of the filling station 4, and at this time, the upper capsule plate 71 and the lower capsule plate 72 have been separated. The filling mechanism 3 is used to quantitatively inject the medicine powder into the capsule body 82. Exemplarily, common filling methods include screw filling and plunger filling. The screw filling pushes the medicine powder into the capsule body 82 through the rotation of the screw, and the filling amount can be controlled by controlling the rotation speed and rotation time of the screw. The plunger filling uses the reciprocating motion of the plunger to quantitatively fill the medicine powder into the capsule body 82, and the filling precision is relatively high. The closing mechanism 4 is used to close the capsule body 82 filled with the medicine powder and the capsule cap 81. The closing mechanism 4 is arranged on one side of the closing station 7, and at this time, the upper capsule plate 71 and the lower capsule plate 72 have been abutted together again. Exemplarily, the closing mechanism 4 includes an upper pressing plate and a lower abutting column. When the abutted upper capsule plate 71 and the lower capsule plate 72 are displaced between the upper pressing plate and the lower abutting column, the abutting driving member drives the lower abutting column to move upward, pushes the capsule body 82 filled with the medicine powder, and tightly presses the capsule body 82 and the capsule cap 81 together, thereby completing the filling and packaging of the capsule. The discharging mechanism 5 pushes the capsule filled with the medicine powder out of the capsule to be collected. The discharging mechanism 5 is arranged on one side of the discharging station 9. Exemplarily, the discharging mechanism 5 includes a lifting rod and a sliding groove. When the capsule is displaced above the lifting rod with the capsule, the lifting rod penetrates through the capsule to push the capsule out, and the capsule falls into a collection box or a collection conveying belt under the action of gravity. The cleaning mechanism 6 is used to blow air to the capsule. The cleaning mechanism 6 is arranged on one side of the cleaning station 10. Exemplarily, the cleaning mechanism 6 uses the air blowing method, and a high-pressure gas jet head is used to spray gas into the capsule to blow out the residual medicine powder. Some also combine cleaning tools such as brushes to mechanically clean some parts that are difficult to blow, so as to ensure the cleanliness of the equipment, clean the medicine powder falling in the capsule, and ensure the cleanliness of the capsule in subsequent re-feeding. Those skilled in the art know the specific structure and working principle of the feeding mechanism 1, the filling mechanism 3, the closing mechanism 4, the discharging mechanism 5 and the cleaning mechanism 6, and details are not repeated here.

[0036] As shown in Figure 2 The center rotating disc 7 moves one station per rotation, wherein, as shown in Figure 2As shown, the center turntable 7 rotates clockwise, ① corresponds to the feeding station, ② corresponds to the supplement station, ③ corresponds to the separation station, ④ corresponds to the filling station, ⑤ corresponds to the transition station, that is, the capsule does not change from ④ to ⑤, ⑥ corresponds to the horizontal reset station, at this time, the lower capsule plate 72 is reset to below the upper capsule plate 71, ⑦ corresponds to the vertical reset station, at this time, the lower capsule plate 72 re-contacts with the upper capsule plate 71, for example, continue to refer to Figure 2 、 Figure 3 and Figure 4 , the lower capsule plate 72 is fixedly arranged at the output end of the second displacement driving member 722, the second displacement driving member 722 is arranged at the output end of the first displacement driving member 721, and the first displacement driving member 721 is arranged on the center turntable 7, the first displacement driving member 721 is used to drive the second displacement driving member 722 to move horizontally along the radial direction of the center turntable 7, and the second displacement driving member 722 is used to drive the lower capsule plate 72 to move reciprocatingly along the vertical direction, ⑧ corresponds to the closing station, ⑨ corresponds to the discharging station, and ⑩ corresponds to the cleaning station.

[0037] It should be noted that the upper capsule plate 71, the lower capsule plate 72, the first displacement driving member 721 and the second displacement driving member 722 are arranged in groups, that is, the present application Figure 2The number of the upper and lower capsule plates and the driving members is 10, which is consistent with the number of the stations. Under the rotation of the center disc 7, the upper and lower capsule plates and the driving members pass through the stations ① to ⑩ in sequence. Specifically, the center disc 7 rotates clockwise, and one of the capsule holders is taken as a target. When the capsule holder is moved to the station ①, the upper capsule plate 71 and the lower capsule plate 72 abut, and the first displacement driving member 721 and the second displacement driving member 722 are both located at the initial position. When the capsule holder is moved to the station ②, the positions of the upper capsule plate 71, the lower capsule plate 72, the first displacement driving member 721 and the second displacement driving member 722 relative to the center disc remain unchanged. When the capsule holder is moved to the station ③, the second displacement driving member 722 is first driven to move the lower capsule plate 72 downward, so that the upper capsule plate 71 and the lower capsule plate 72 are vertically separated. Then, the driving end of the first displacement driving member 721 is extended outward, and the lower capsule plate 72 is moved along the horizontal direction away from the center disc 7, so that the upper capsule plate 71 and the lower capsule plate 72 are horizontally misaligned. When the capsule holder is moved to the station ④, the misaligned lower capsule plate 72 exposes the capsule body 82 at the outlet of the medicine powder injection device, and the medicine filling is performed. When the capsule holder is moved to the station ⑤, the positions of the upper capsule plate 71, the lower capsule plate 72, the first displacement driving member 721 and the second displacement driving member 722 relative to the center disc remain unchanged. When the capsule holder is moved to the station ⑥, the first displacement driving member 721 is first reset to move the lower capsule plate 72 toward the center disc 7 to be directly below the upper capsule plate 71. When the capsule holder is moved to the station ⑦, the second displacement driving member 722 is reset to move the lower capsule plate 72 upward to abut the upper capsule plate 71. When the capsule holder is moved to the stations ⑧, ⑨ and ⑩ in sequence, the positions of the upper capsule plate 71, the lower capsule plate 72, the first displacement driving member 721 and the second displacement driving member 722 relative to the center disc remain unchanged. When the capsule holder is moved to the station ① again, the above-mentioned actions can be repeated.

[0038] For example, the first displacement driving member 721 is an electric telescopic cylinder or a hydraulic telescopic cylinder, which is not limited here. The second displacement driving member 722 is an electric telescopic cylinder or a hydraulic telescopic cylinder, which is not limited here.

[0039] For example, continuing to refer to Figure 4 , Figure 5 and Figure 6The lower capsule plate 72 is provided with a plurality of capsule holes 724 and a plurality of stepped holes 723, the capsule holes 724 and the stepped holes 723 are correspondingly communicated, the capsule hole 724 is located above the stepped hole 723, the aperture size of the capsule hole 724 is larger than that of the stepped hole 723, the capsule separation and detection assembly comprises a supporting plate 725 and a pressure sensor 726, the supporting plate 725 is fixedly arranged in each capsule hole 724, the side of the supporting plate 725 away from the stepped hole 723 is provided with a circular arc concave supporting surface, the radius of the circular arc concave supporting surface is consistent with that of the circular arc convex surface of the capsule body 82, and the edge of the circular arc concave supporting surface of the supporting plate 725 is embedded with the pressure sensor 726. After the loading and separation of the capsules are completed in the loading station, for the separated capsules, the capsule body 82 falls on the supporting plate 725 under the action of gravity, at this time, the pressure sensor 726 is extruded, that is, the pressure sensor 726 detects the signal of the separation of the capsule body 82, and then the separation assembly is not needed 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 indicates that the capsule at this position is not successfully separated, and then the separation assembly needs to perform the separation operation on the capsule.

[0040] It should be noted that the stepped hole 723 is used for connecting the air outlet of the vacuumizing device, so that the vacuumizing device can perform the vacuumizing action on the capsule hole 724 through the stepped hole 723, and when the closing mechanism 4 performs the closing operation, the top rod in the closing mechanism 4 pushes the capsule body 82 filled with the medicine powder in the capsule hole 724 into the capsule cap 81 through the stepped hole 723 to complete the closing.

[0041] For example, continuing to refer to Figure 4 and Figure 5 The upper capsule plate 71 and the lower capsule plate 72 are sealingly abutted between the replacement stations. By correspondingly embedding the sealing rings on the end faces of the upper capsule plate 71 and the lower capsule plate 72, when the two abut, the abutting position of the upper capsule plate 71 and the lower capsule plate 72 is sealed and air-tight by the abutting of the sealing rings, so that the vacuumizing force on the capsule body 82 is ensured.

[0042] For example, continuing to refer to Figure 4 and Figure 5 The separation assembly comprises a rotating assembly and a pulling-down assembly, the rotating assembly is arranged in the upper capsule plate 71, and the pulling-down assembly is arranged in the lower capsule plate 72, the rotating assembly is used for clamping and rotating the capsule cap 81 of the capsule which is not separated in the circumferential direction, and the pulling-down assembly is used for applying a pulling force to the capsule body 82 of the capsule which is not separated in the direction away from the capsule cap 81. Through the circumferential rotation of the capsule cap 81 and the pulling-down of the capsule body 82, the cooperative action of the rotation and the pulling-down can destroy the static friction force between the capsule cap 81 and the capsule body 82, reduce the separation resistance, overcome the occlusion resistance between the capsule cap 81 and the capsule body 82, and make the capsule body 82 pull down and separate the capsule cap 81 smoothly.

[0043] With reference to the accompanying drawings, the present application will be described in detail. Figure 4 、 Figure 5 、 Figure 7 and Figure 8 The indexing assembly comprises a rotating drum 711, an indexing seat 715, a motor 75 and a third displacement drive 73. The rotating drum 711 is rotatably installed in the upper capsule plate 71. A flange is arranged at the lower edge of the inner drum wall of the rotating drum 711. The capsule cap 81 is located in the cavity of the rotating drum 711 and overlaps the flange. The output end of the third displacement drive 73 is drivingly connected with a support frame 74. A plurality of motors 75 are arranged on the support frame 74. The motors 75 are arranged in correspondence with the rotating drum 711. The output end of the motor 75 is drivingly connected with the indexing seat 715. The lower end of the indexing seat 715 is provided with a clamping column 713. A clamping groove 712 is formed in the rotating drum 711. The clamping column 713 and the clamping groove 712 are arranged in correspondence with each other. The lower end of the indexing seat 715 is further provided with an abutting pad 714. The abutting pad 714 is used for abutting and fixing the capsule cap 81 to be rotated.

[0044] When the pressure sensor 726 detects that the capsule is not separated, the third displacement drive 73 is started. The third displacement drive 73 is exemplarily a hydraulic telescopic cylinder or an electric telescopic cylinder, which is not limited herein. The clamping column 713 is clamped in the clamping groove 712. The abutting pad 714 abuts on the arc convex surface of the capsule cap 81. The capsule cap 81 is fixed in the rotating drum 711. The motor 75 drives the indexing seat 715 to rotate. The indexing seat 715 drives the rotating drum 711 to rotate through the clamping column 713, so as to realize the rotation of the capsule cap 81.

[0045] As shown in Figure 8 and Figure 9 The lower pulling assembly comprises a fourth displacement drive 727, an upper bracket 729, a lower bracket 733, a conveying belt 732 and air bags 731. The output end of the fourth displacement drive 727 is drivingly connected with a support 728. The upper bracket 729 and the lower bracket 733 are rotatably connected with the support 728, respectively. The input end of the lower bracket 733 is drivingly connected with a motor. The upper bracket 729 and the lower bracket 733 are drivingly connected through the conveying belt 732. The air bags 731 are uniformly arranged on the conveying belt 732. When the capsule is not separated, the air bags 731 are in frictional abutment with the side wall of the capsule body 82 under the driving of the fourth displacement drive 727. Before the motor 75 is started, the fourth displacement drive 727 is started to drive the support 728 to move towards the capsule body 82 until the air bags 731 abut on the capsule body 82. Then, the motor 75 is started at the same time. The motor is started to drive the conveying belt 732 to rotate. Figure 9As shown, the conveying belt 732 rotates clockwise, the air bags 731 are abutted on the capsule body 82 one by one and drag the capsule body 82 to move downward, so as to realize the pulling operation of the capsule body 82, and the conveying belt 732 symmetrically arranged on the other side of the capsule body 82 rotates counterclockwise, so as to realize the multi-point abutting and dragging of the capsule body 82.

[0046] For example, continuing to refer to Figure 9 and Figure 11 The upper bracket 729 is provided with a baffle 734 on the two axial sides, the baffle 734 is fixedly arranged on the support 728, the baffle 734 is fixedly provided with an extrusion plate 730, the side of the extrusion plate 730 facing the capsule body 82 is a vertical surface, and the length of the vertical surface of the extrusion plate 730 is greater than the distance between the two air bags 731. So that at least two air bags 731 abut on the capsule body 82 at the same time, so as to increase the pulling abutting friction force of the capsule body 82.

[0047] For example, continuing to refer to Figure 9 In the initial state, the air bag 731 protrudes symmetrically towards the two sides of the conveying belt 732. When the conveying belt 732 is wound on the upper bracket 729, the side of the air bag 731 facing the upper bracket 729 is extruded, so that the air bag 731 is extruded to bulge away from the upper bracket 729, so that the abutting force on the capsule body 82 is enhanced when the air bag 731 abuts on the capsule body 82, and the air bag 731 returns to the initial state when it is extruded.

[0048] The lower bracket 733 is a waist drum structure, so that when the conveying belt 732 is wound on the lower bracket 733, the waist drum region of the waist drum structure is used to accommodate the air bag 731, so as to avoid the additional extrusion deformation of the air bag 731 which is not in the abutting position of the capsule body 82, and ensure the service life of the air bag 731.

[0049] It should be noted that, in use, the center rotating disc 7 rotates, so that the capsule passes through the feeding station, the supplement station, the separation station, the filling station, the transition station, the horizontal reset station, the vertical reset station, the closing station, the discharging station and the cleaning station in sequence, so as to complete the complete filling and packaging of the capsule. Wherein, after the capsule is transferred to the supplement station, if there is a capsule that is not separated, the capsule body 82 is not supported on the corresponding supporting plate 725, at this time, the pressure sensor 726 is not extruded by the capsule body 82, the third displacement driving part 73 is started according to the signal that the pressure sensor 726 is not extruded by the capsule body 82, the supporting frame 74 is moved downward to be clamped with the clamping column 713 and the clamping groove 712, the abutting pad 714 abuts and fixes the cap 81, and the fourth displacement driving part 727 is started, the bracket 728 moves rightward, so that the air bag 731 abuts and rubs with the capsule body 82.

[0050] The starting motor 75 drives the indexing seat 715 to rotate the rotating drum 711, and the cap 81 rotates with the rotating drum 711. Meanwhile, the motor is started, the lower bracket 733 rotates, and drives the conveying belt 732 to rotate, so that the plurality of air bags 731 abut against the capsule body 82 in sequence to move downward, thereby realizing the rotation of the cap 81 and the downward movement of the capsule body 82, which is helpful to the smooth separation of the cap 81 and the capsule body 82, thereby ensuring that each capsule is filled with drugs during subsequent drug filling, avoiding the occurrence of waste capsules and invalid drug filling, and saving raw materials.

[0051] The above-described embodiments only express several embodiments of the present application, which are described in detail and specifically, but cannot be understood as a limitation on the scope of the patent of the present application. It should be noted that, for ordinary skilled persons in the art, several modifications and improvements can be made without departing from the concept of the present application, which are within the protection scope of the present application.
