When a problem occurs in the filling machine 31, the stop cylinder 12 drives the stop plate to be placed on the conveying path of the loading conveyor belt 11, and stops further conveying the bottles to the conveying assembly 2.

[0024] like Figure 1~Figure 2 As shown, the conveying assembly 2 includes: a conveying turntable 21 and a conveying guard plate 22; A bottle groove 23 is formed on the edge of the conveying turntable 21 for placing bottles. The bottle groove 23 is configured to correspond to the shape of the bottles. The conveying guard plate 22 is annular and is sleeved on the outer side of the conveying turntable 21. The conveying guard plate 22 is configured to prevent the bottles from escaping from the bottle groove 23.

[0028] When the conveying assembly 2 conveys the bottle body to the bottom of the filling nozzle 32, the filling machine 31 provides the filling nozzle 32 with liquid for filling, and the synchronous motor 34 drives the filling nozzle 32 to rotate, and the filling nozzle 32 is directed toward the bottle mouth of the bottle body to fill the liquid into the bottle body. The synchronous column 33 moves synchronously with the bottle body to make the relative position of the filling nozzle 32 and the bottle body inconvenient, thereby ensuring that the filling nozzle 32 continues to fill the liquid into the bottle body.

[0029] In this embodiment, a total of eight filling nozzles 32 are provided, and each filling nozzle 32 is provided with a synchronous motor 34. When eight bottles to be filled move to the filling assembly 3, the filling machine 31 simultaneously provides filling liquid to the eight filling nozzles 32, and the synchronous motor 34 drives the filling nozzles 32 to rotate to fill the bottles. The synchronous column 33 drives the filling nozzles 32 to move synchronously with the bottles. When the bottles move to the positions of six bottle slots 23, the filling of the eight filling nozzles 32 is completed, and the bottles filled in the first filling part enter the second filling part 4.

[0032] In this embodiment, there are three filling tubes 42, and the liquid storage tank 41 outputs liquid to the three filling tubes 42 at the same time. The driving member 44 can be a motor, a hydraulic cylinder or a cylinder, as long as it can drive the piston 43 to move in the filling tube 42. According to the needs, the filling component 3 also includes a third filling part, which is a quantitative filling device to realize the gradual filling of multiple liquids.

[0033] like Figure 7 As shown, the positioning mechanism includes: a bottle mouth clamping cylinder, a servo motor, a positioning drive mechanism 52, a positioning slot 53 and a top cover block 54; The positioning slot 53 is connected to the driving mechanism, and the top cover block 54 is arranged above the positioning slot 53. Under the drive of the driving mechanism, the top cover block 54 is suitable for removing the bottle cap on the loader 51.

[0036] like Figure 8 As shown, the capping mechanism comprises: a mechanical clamp 55, a capping motor 56 and a capping linear mechanism 57; The capping motor 56 is arranged at the output end of the capping linear mechanism 57, and the output end of the capping motor 56 is connected to the mechanical gripper 55, and the mechanical gripper 55 is used to grab the bottle cap on the top cover block 54, and the capping motor 56 is used to drive the mechanical gripper 55 to screw the bottle cap onto the bottle mouth.

[0038] like Figure 9~Figure 10 As shown, the detection assembly 7 includes: a filling detection mechanism 71 and a bottle cap detection mechanism 72; The filling detection mechanism 71 is arranged between the filling assembly 3 and the capping assembly 5, and is used to detect the filling status of the bottle body. The bottle cap detection mechanism 72 is arranged between the capping assembly 5 and the blanking assembly 6, and is used to detect the bottle cap on the bottle body.

[0039] After the filling assembly 3 completes filling of the bottle body, the filling detection mechanism 71 detects the filling status of the bottle body and records the detection result. After the capping assembly 5 screws the bottle cap onto the bottle body, the bottle cap detection mechanism 72 can detect whether there is a bottle cap on the bottle body.

[0040] In this embodiment, both the filling detection mechanism 71 and the bottle cap detection mechanism 72 are visual detection mechanisms, which can quickly detect defective products due to unqualified filling and defective products due to unsuccessful screwing of the bottle cap.

[0041] like Figure 11~Figure 13As shown, the blanking assembly 6 includes: a defective product blanking mechanism 61 and a good product blanking mechanism 62; When any one of the filling detection mechanism 71 and the bottle cap detection mechanism 72 detects that the bottle body is defective, the defective product unloading mechanism 61 unloads the bottle body; when the filling detection mechanism 71 and the bottle cap detection mechanism 72 detect that both the bottle bodies are good, the good product unloading mechanism 62 unloads the bottle body.

When the capping detection mechanism 622 detects that the bottle cap is not tightened, the dividing cylinder 623 pushes the bottle body onto the dividing conveyor belt 624, and the bottles in a normal tightening state continue to be conveyed by the good product conveyor belt 621 for collection.

[0044] In this embodiment, the defective product unloading mechanism 61 is a belt transmission device, and the capping detection mechanism 622 takes pictures of the bottle caps through a 360° camera and determines the tightening condition of the bottle caps through visual detection.
