The filling station 13 is used to dislocate the upper mold assembly 2 and fill the opened empty capsules in the upper mold assembly 2 with materials. The blank station 14 is used to reset the upper mold assembly 2. The capsule closing station 15 is used to close the capsules 9 in the upper mold assembly 2. The second detection station 16 is used to detect whether the capsules 9 in the upper mold assembly 2 have been filled. The capsule demoulding and bottling station 17 is used to eject qualified capsules in the upper mold assembly 2 into the material bottle 93. The emptying station 18 is used to eject unqualified capsules in the upper mold assembly 2 into the emptying receiving tray 74.

[0034] During operation, the empty capsule is conveyed to the upper mold assembly 2 on the empty capsule opening station 11, the empty capsule is opened, the capsule cap 92 and the capsule body 91 are separated and the capsule cap 92 is supported in the upper mold assembly 2, and the capsule body 91 is supported on the turntable mechanism 1. Under the action of the turntable mechanism 1, the opened empty capsule is rotated to the first detection station 12 for empty capsule detection. If an empty capsule is detected, the turntable mechanism 1 continues to rotate and rotates the empty capsule to the filling station 13. In the filling station 13, the capsule cap 92 and the capsule body 91 are misaligned, and the material is filled into the capsule body 91. After the filling is completed, the turntable mechanism 1 continues to rotate. When passing through the blank station 14, the capsule cap 92 and the capsule body 91 are misaligned. The body 91 is reset, and the turntable mechanism 1 continues to rotate to rotate the capsule cap 92 and the filled capsule body 91 to the capsule closing station 15, and the capsule cap 92 and the filled capsule body 91 are closed, and then the turntable mechanism 1 continues to rotate to rotate the closed capsule 9 to the second detection station 16 to detect the closed capsule 9. If it is detected that the closed capsule 9 has been filled with material, it is determined to be a qualified capsule, otherwise it is an unqualified capsule. Finally, the turntable mechanism 1 continues to rotate to rotate the qualified capsule to the capsule demoulding and bottling station 17 to eject the qualified capsule from the upper mold assembly 2 into the material bottle 93, or rotate the unqualified capsule to the emptying station 18 to eject the unqualified capsule from the upper mold assembly 2 into the emptying receiving tray 74. In this way, the opening of empty capsules, the filling of empty capsules, the capsule packaging, and the demoulding and bottling of capsules can be fully automatically realized, which can maintain the cleanliness of capsule drug production and improve work efficiency.

[0035] The turntable mechanism 1 includes a servo motor 31, a main shaft 32, a base plate 33, a dividing plate 34, a cam 35, and a panel 36. The dividing plate 34 is fixedly mounted on the main shaft 32. The base plate 33 and the cam 35 are respectively connected to the main shaft 32 through a first bearing 37, and the dividing plate 34 is located between the base plate 33 and the cam 35. The upper mold assemblies 2 on the eight workstations are arranged on the dividing plate 34 and are distributed in a circle around the cam 35. The servo motor 31 is arranged on the base plate 33, and the output end of the servo motor 31 is connected to the main shaft 32. The panel 36 is located above the cam 35 and connected to the cam 35.

[0036] When the turntable mechanism 1 is working, the servo motor 31 drives the main shaft 32 to rotate, and the main shaft 32 drives the indexing plate 34 and the upper mold assembly 2 arranged on the indexing plate 34 to rotate, while the cam 35 and the bottom plate 33 do not rotate.

[0037] The upper mold assembly 2 includes a first fixed block 21, a second fixed block 22, a guide shaft 23, a guide sleeve 24, a movable platform 25, a roller assembly 26, a template 27, and a tension spring assembly 28.

When the upper mold assembly 2 rotates with the indexing plate 34, the outer wall edges of the roller 263 and the cam 35 rotate and contact, which can reduce the wear of the roller 263 and the cam 35. Then, when the upper mold assembly 2 rotates with the indexing plate 34 to the high position of the cam 35, the high position of the cam 35 pushes the movable platform 25 along the guide shaft 23 to move away from the first fixed block 21 through the roller 263, and the tension spring assembly 28 is deformed, so that the capsule cap 92 located in the empty capsule feeding channel 272 and the capsule body 91 located on the indexing plate 34 are misaligned, and the capsule body 91 and the filling channel 271 are located on the same straight line (such as Figure 8 As shown in FIG. 2 ), the material enters the capsule body 91 through the filling channel 271. After the filling is completed, the upper mold assembly 2 rotates with the indexing plate 34 to leave the high position of the cam 35 and arrive at the blank station 14. The tension spring assembly 28 recovers its deformation to reset the moving platform 25, so that the capsule cap 92 and the capsule body 91 filled with the material are located on the same straight line (as shown in FIG. 2 ). Fig. 9 Then, when the upper mold assembly 2 rotates with the indexing plate 34 to the capsule closing station 15, the capsule cap 92 is firmly covered on the capsule body 91 (as shown in FIG. Figure 6 As shown), finally, when the upper mold assembly 2 rotates with the indexing plate 34 to the capsule ejection and bottling station 17, the capsule 9 is ejected from the empty capsule discharge channel 272 into the bottle 93.
