A finger 21 for cleaning the cleaning unit 4 is mounted on a first guide unit 22, which can be driven by a servomotor 25 using a synchronizing pulley 24 and a synchronizing belt 23. The vial 17 for the infusion solution is installed on the finger 21 for cleaning for transfer to the cleaning point.

Figures 5 and 6 show a cleaning unit 4, which further comprises, in addition to the finger 21, mentioned above, a cleaning nozzle 31 for cleaning. The cleaning nozzle 31 is mounted on the second mounting plate 32 and can be extended by the cylinder 34 to move upward along the pair 33 of guide rails and insert into the vial 17 for the infusion solution to clean the inner cavity of the vial.

7 and 8 depict a flipping device 5 that includes a first gas gripper 41, a main rod 42 and a pair of rotating cylinders 43. A first gas gripper 41 is mounted on the main rod 42, and the main rod 42 is mounted on a pair of rotating cylinders 43. The rotating cylinders 43 this pair is respectively mounted on the servo mechanisms 44, and the servo mechanisms 44 can be driven to be moved in parallel by the servo motor 45 using the timing belt 46 and axles 47. After raising the drug vial 17 Islands with the pin 21 to clean the first gas grip 41 first moves slightly forward, then is inverted and then moves forward again and set to the finger 51 for filling fill assembly 7 thus completes inversion and transfer operation.

Fig.9 depicts a main conveyor guide device 6, which contains a second guide unit 52. A finger 51 for filling the filling unit 7 is mounted on a second guide unit 52, which can be driven to be moved by a servomotor 55 using a synchronization pulley 54 and a synchronization belt 53. The drug bottle 17 mounted on the finger 51 to fill the filling unit 7 is transferred to the filling point from the overturn point, then transferred to the blocking point after completion Nia filling and, as a result, is transmitted to the point of delivery of the vial.

10 shows a filling unit 7 and a clogging unit 8. The filling unit 7 further comprises, in addition to the filling finger 51, mentioned above, a filling head 61. The filling head 61 is mounted on the third mounting plate 62 and may be driven by a cylinder 64 to move downward along the pair 63 of guide rails for insertion into the neck of the filling bottle. After filling the bottle 17 for the drug is transferred to the clogging point. The cylinder 74 moves downward and the guide plate 73 opens the pivot plate 71 by means of the roller 72 and presses the combination cap 70 to connect it together with the drug bottle 17.

11 and 12 depict the bottle delivery unit 9, which contains the fourth gas capture 82. The fourth gas capture 82 is suspended under the rodless cylinder 81 on the mounting plate 83. After passing the filled drug bottle 17 to this point, the fourth gas capture 82 clamps the neck of the bottle 17 for the drug and removes the bottle 17 for the drug under the action of the traction force of the rodless cylinder 81.
