[0014] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.
[0015] See Figures 1 to 3 This embodiment discloses a cigarette pack missing pack removal device. The frame 1 of the cigarette elevator is provided with a vertical lifting channel 2, and the cigarette pack missing pack removal device is provided in front of the vertical lifting channel 2. The cigarette pack missing pack removal device includes a cigarette baffle structure 3 and a cigarette suction structure 4.
[0016] The cigarette bar baffle structure 3 includes two baffle strips 5 positioned on the left and right sides in front of the vertical lifting channel 2. Each baffle strip 5 is a vertically extending strip-shaped structure. A baffle drive mechanism drives the two baffle strips 5 to move simultaneously in opposite directions in the left and right directions, so that the two baffle strips 5 correspond to or are offset from the vertical lifting channel 2. The baffle drive mechanism is a baffle cylinder 6. The left and right output ends of the baffle cylinder 6 are connected to the two baffle strips 5 respectively via connectors 7. The baffle cylinder 6 is mounted on a baffle cylinder fixing component 8. A fixing plate 9 is provided on one side of the frame 1 of the cigarette bar elevator, and the baffle cylinder fixing component 8 is mounted on the fixing plate 9.
[0017] The baffle cylinder fixing component 8 is an L-shaped plate composed of plate one and plate two. Plate one of the baffle cylinder fixing component 8 is attached to the front side of the baffle cylinder 6 and has a first oblong hole 10 extending in the left and right directions. Plate two of the baffle cylinder fixing component 8 is attached to the left side of the fixing plate 9 and has a second oblong hole 11 extending in the front and back directions. The baffle cylinder fixing component 8 is locked and installed with the baffle cylinder 6 and the fixing plate 9 by passing a bolt through the first oblong hole 10 and tightening it. Loosening the bolts allows for fine-tuning of the front-back and left-right positions of the baffle cylinder 6 due to the first oblong hole 10 and the second oblong hole 11. This enables fine-tuning of the front-back and left-right positions of the two baffle strips 5 installed on the baffle cylinder 6, ensuring they are in the correct positions. When the cigarette bar elevator is working normally, these baffle strips can support the front of the cigarette bar 16 in the vertical lifting channel 2, preventing the cigarette bar 16 from falling.
[0018] The cigarette suction structure 4 includes a suction cup plate 12 disposed on the front side of the vertical lifting channel 2 and a suction cup assembly 13 disposed on the suction cup plate 12. In this embodiment, the suction cup plate 12 is provided with two suction cup assemblies 13, one above the other, to achieve stable adsorption of the cigarette packs 16. The suction cup assembly 13 is located between the two left and right baffle strips 5. The suction cup plate 12 is driven to move back and forth by the suction driving mechanism to adsorb and remove the missing cigarette packs 16 in the vertical lifting channel 2.
[0019] The suction drive mechanism includes a suction cylinder 14. The output end of the suction cylinder 14 is connected to the front end of the suction plate 12. The suction cylinder 14 is mounted on the suction cylinder fixing part 15, which is fixedly mounted on the fixing plate 9.
[0020] When the cigarette lifting machine is working, the cigarette conveying chain of the vertical lifting channel 2 starts, conveying the cigarettes 16 from bottom to top. At this time, the left and right output ends of the baffle cylinder 6 in the cigarette baffle structure 3 are in a retracted state, and the two baffle bars 5 are located in front of the vertical lifting channel 2, supporting the front of the cigarettes 16 being conveyed upward, so that the cigarettes 16 are conveyed smoothly; at the same time, the suction plate 12 in the cigarette suction structure 4 is in a forward retracted state, away from the vertical lifting channel 2, so as not to affect the smooth conveying of the cigarettes 16.
[0021] When the cigarette pack missing detection device on the cigarette lifting machine detects a missing pack of cigarettes 16, the left and right output ends of the baffle cylinder 6 immediately extend, driving the two baffle strips 5 to move to the left and right sides of the vertical lifting channel 2, exposing the front of the missing pack of cigarettes 16. The output end of the suction cylinder 14 also immediately extends backward, driving the suction plate 12 and its two suction cup assemblies 13 to move backward and approach the missing pack of cigarettes 16, using the two suction cup assemblies 13 to hold the missing pack of cigarettes 16. Then, the output end of the suction cylinder 14 retracts forward, promptly removing the adsorbed missing pack of cigarettes 16 from the vertical lifting channel 2. After the missing pack of cigarettes 16 is removed, the left and right output ends of the baffle cylinder 6 retract again, driving the two baffle strips 5 back to their original positions, continuing to support the conveyed packs. The entire process does not affect the normal conveying of cigarettes 16, achieving online removal of the missing pack of cigarettes 16.
[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
