Based on the embodiments in the utility model, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model. Please refer to Figures 1-6 .

[0024] As Figure 1As shown, a cigarette buffer vertical warehouse includes a tower rack 1, a vertical lifting storage system 2, a cigarette lifting mechanism 3, and a cigarette conveyor 4. The vertical lifting storage system 2, the cigarette lifting mechanism 3, and the cigarette conveyor 4 are arranged in the tower rack 1. The vertical lifting storage system 2 has a left-right symmetrical structure, and the cigarette conveyor 4 is arranged in the middle. The cigarette lifting mechanism 3 is arranged below the cigarette conveyor 4. The vertical lifting storage system 2 and the cigarette lifting mechanism 3 are controlled by a sensor 36 on the cigarette lifting mechanism 3. The utility model can effectively avoid the accumulation and loss of cigarettes. In the tobacco production, the "roll and pack" process speed is continuously improved. When the automatic packing machine suddenly stops, if the subsequent automatic conveying line cannot stop in time, a large amount of finished cigarettes will be squeezed and stacked on the conveying line. The cigarette buffer vertical warehouse of the utility model is arranged on the conveying line in front of the packing machine, and can be quickly started when the packing machine fails to receive the cigarettes. After the vertical lifting storage system and the cigarette lifting mechanism cooperate, the cigarettes are stored in time, the wear and loss caused by long-time squeezing and friction are avoided, and the product quality is ensured.

[0025] As shown in Figure 2 , 3 , 4, further, the vertical lifting storage system 2 includes a main transmission shaft system 21, a double-sided plate chain 22, a C-shaped limiting block 23, a C-shaped guide rail 24, a right-angle bracket strip 25, and a driven wheel 26. The main transmission shaft system 21 has two groups of left-right symmetrical structures. The main transmission shaft system includes a main transmission shaft 211, a transmission motor 212, and two main transmission wheels 213. The transmission motor 212 is located on one side of any main transmission wheel 213, and the two main transmission wheels 213 are connected by the main transmission shaft 211. The main transmission shaft system is vertically hung below the rack beam of the tower rack 1. The double-sided plate chain 22 is fixed on the double C-shaped guide rail 24. The C-shaped limiting block 23 is fixed outside the double-sided plate chain 22 in sequence. The right-angle bracket strip 25 is horizontally installed on the C-shaped limiting block 23. The driven wheel 26 is arranged on the top of the tower rack 1.

[0026] Further, the distance between the two right-angle bracket strips 25 is smaller than the length of the cigarette by 20-30 mm.

[0027] As shown in Figure 5 and Figure 6 , further, the cigarette lifting mechanism 3 includes a U-shaped lifting frame 31, a horizontal cross plate 32, a cylinder 33, a support beam 34, a conveying motor 35, and a sensor 36. The U-shaped lifting frame 31, the horizontal cross plate 32, the cylinder 33, and the support beam 34 are arranged below the cigarette conveyor 4 in sequence. The conveying motor 35 is fixed on one side of the cigarette conveyor 4. The sensor 36 is fixed on the conveying motor 35.

[0028] Further, the distance between the U-shaped lifting frame 31 on both sides of the lifting block is less than the distance between the two straight angle bracket strips 25 of the vertical lifting storage system 2, and is greater than the cross-sectional dimension of the cigarette conveyor 4.

[0029] The vertical lifting storage system of the utility model adopts two active transmission shaft systems, double-sided plate chains, C-shaped limiting blocks, double C-shaped guide rails, straight angle bracket strips and driven wheels and other components to cooperate, ensures the stable lifting and storage of the cigarettes in the vertical direction, and the U-shaped lifting frame, horizontal cross plate, cylinder, support beam, transmission motor and sensor of the cigarette lifting mechanism ensure the safety and smoothness of the cigarettes in the lifting process.

[0030] The utility model works as follows: when normally operating, the U-shaped lifting frame 31 of the cigarette lifting mechanism 3 is lower than the top of the cigarette conveyor 4, and the cigarettes are normally conveyed to the automatic cartoning machine.

[0031] When the automatic cartoning machine fails to receive the cigarettes, the cigarettes are horizontally squeezed and queued on the cigarette conveyor 4, and stay on the jacking mechanism for a long time, triggering the sensor to control the main transmission shaft system 21 to work, and the two transmission motors 212 of the vertical lifting storage system 2 drive the double-sided plate chains 22 and C-shaped limiting blocks 23 to move on the double C-shaped guide rails 24, and drive the straight angle bracket strips 25 to be lifted in turn; at the same time, the cylinder 33 works, and the U-shaped lifting frame 31 drives the horizontal cross plate 32 to lift the cigarettes to a certain height away from the working surface of the cigarette conveyor 4, avoiding the friction between the cigarette conveyor 4 and the cigarettes. After the U-shaped lifting frame 31 is lifted, it returns to the original position below the working surface of the cigarette conveyor 4, and the subsequent arriving cigarettes repeat the lifting and lifting actions, realizing the storage of the cigarettes.

[0032] When the straight angle bracket strips 25 of the same vertical height are full of cigarettes, the two transmission motors 212 of the vertical lifting storage system 2 work to lift the straight angle bracket strips 25 to a certain height.

[0033] After the front end fault is eliminated, the cylinder 33 works, the U-shaped lifting frame 31 drives the horizontal cross plate 32 to rise synchronously, the two transmission motors 212 of the vertical lifting storage system 2 work to make the straight angle bracket strips 25 move downward once, and the whole layer of cigarettes is placed on the horizontal cross plate 32, and the cigarettes are placed on the conveyor belt in the order from front to back, and the cigarettes are normally conveyed to the automatic cartoning machine.

[0034] The running process of the cigarette strip buffer vertical warehouse is highly automated. When the automatic cartoning machine fails, the sensor can timely sense the state change of the cigarette strip and automatically trigger the vertical lifting storage system and the cigarette strip lifting mechanism to work; after the front-end fault is eliminated, the device can automatically put the stored cigarette strip back to the conveying belt to continue the normal cartoning process. The whole process does not need too much manual intervention, reduces the complexity and labor intensity of manual operation, and improves the production efficiency and the reliability of the equipment operation.
