Description

TECHNICAL FIELD

[0001] The utility model belongs to the tobacco processing technical field, concretely relates to a carton cigarette conveying system convenient for unqualified product tracing. BACKGROUND

[0002] The existing carton cigarette conveying system is a conveying system conveying carton cigarettes produced by multiple packaging machines (generally 3 to 5 packaging machines) to a carton sealing machine for boxing, which comprises multiple conveying branch lines connected with the outlets of the multiple packaging machines and a conveying main line connected with the inlet of the carton sealing machine, and the multiple conveying branch lines are all converged to the conveying main line, so that the carton sealing machine boxes the carton cigarettes from the multiple packaging machines in one carton, and if a packaging machine malfunctions to produce unqualified carton cigarettes, it is difficult and cumbersome to find the carton cigarettes from the malfunctioning packaging machine in each carton. SUMMARY

[0003] In order to solve the problems of the prior art, the utility model provides a carton cigarette conveying system convenient for unqualified product tracing, which installs a carton cigarette buffering device in the conveying branch line, and when the carton sealing machine boxes, it only supplies the carton sealing machine with carton cigarettes through one conveying branch line, and the remaining conveying branch lines without supplying the carton sealing machine with carton cigarettes buffer the carton cigarettes, waiting for their turn to supply the carton sealing machine with carton cigarettes, and the buffered carton cigarettes and the carton cigarettes in the conveying branch line are supplied together, so that the carton cigarettes in one carton are only from the same packaging machine, and if the carton cigarettes produced by the malfunctioning packaging machine are unqualified, it is only necessary to find the cartons containing the carton cigarettes, without the need to find the carton cigarettes in each carton.

[0004] This utility model discloses a cigarette pack conveying system for easy traceability of defective products. It includes multiple conveyor branches connected to the outlets of multiple packaging machines and a main conveyor line connected to the inlet of a carton sealing machine. All the multiple conveyor branches converge onto the main conveyor line. The system also includes cigarette pack buffering devices, the same number as the conveyor branches, with one device installed on each conveyor branch. Each cigarette pack buffering device includes a frame, a small conveyor, a lifting storage platform, and a cigarette pack pushing mechanism. The small conveyor is mounted on the frame and inserted into its corresponding conveyor branch. The lifting storage platform is mounted on the frame and arranged parallel to the small conveyor, used for storing cigarette packs. The cigarette pack pushing mechanism is mounted on the frame and located above the small conveyor and the lifting storage platform, used to push cigarette packs from the small conveyor. The cigarette pushing mechanism includes a guide rail, a slide table, a slide table pushing mechanism, a pusher plate A, and a pusher plate B. The slide table reciprocates along the guide rail above the small conveyor and the lifting storage platform under the push of the slide table pushing mechanism. Pusher plate A is rotatably mounted on the slide table. When pusher plate A is rotated upwards to a high position, its bottom surface is higher than the cigarettes on the small conveyor. When pusher plate A is rotated downwards to a low position, it can push the cigarettes on the small conveyor onto the lifting storage platform along with the movement of the slide table. Pusher plate B is also rotatably mounted on the slide table. When pusher plate B is rotated upwards to a high position, its bottom surface is higher than the cigarettes on the lifting storage platform. When pusher plate B is rotated downwards to a low position, it can push the cigarettes on the lifting storage platform onto the small conveyor along with the movement of the slide table.

[0005] The working principle of this utility model's cigarette conveying system for easy traceability of defective products is as follows: First, each cigarette buffer device performs buffering operations. Each conveyor branch conveys the cigarettes to its corresponding small conveyor. The lifting storage platform rises to the same height as the small conveyor, and push plates A and B flip upwards to their high positions. In this state, the bottom surfaces of push plates A and B are higher than the cigarettes on the small conveyor and the lifting storage platform. In this way, push plates A and B can avoid the cigarettes during the movement of the slide table. Then, the slide table pushing mechanism pushes the slide table to move above the small conveyor, and push plate A moves downwards. When the slide is flipped to the low position, the slide pusher mechanism moves the slide to above the lifting storage platform. Pusher A moves with the slide and pushes the cigarette packs on the small conveyor onto the lifting storage platform. Pusher A flips upward to the high position, and the lifting storage platform moves downward by the height of one cigarette pack. At the same time, the slide pusher mechanism moves the slide back to above the small conveyor. Pusher A flips downward to the low position, and the slide pusher mechanism moves the slide to above the lifting storage platform. Pusher A moves with the slide and pushes the cigarette packs on the small conveyor onto the cigarette packs already stored on the lifting storage platform. This is how cigarette packs are stored. Then, a conveyor branch line is selected to supply material to the downstream carton sealing machine. The cigarette packing device installed on this conveyor branch line takes out the cigarette packs and transfers them to the small conveyor. The cigarette packs enter the carton sealing machine for packing via the conveyor branch line and the main conveyor line. When the buffered cigarette packs are taken out, push plates A and B flip upward to the high position. The slide table pushing mechanism pushes the slide table to move above the lifting storage platform. Push plate B flips downward to the low position. The slide table pushing mechanism pushes the slide table to move above the small conveyor. Push plate B, along with the slide table, pushes the top layer of cigarette packs on the lifting storage platform onto the small conveyor. The cigarette packs are then conveyed towards the carton sealing machine via the small conveyor. Push plate B flips upward. When the cigarette storage platform is moved to a higher position, it rises one pack height. At the same time, the sliding table pushing mechanism pushes the sliding table to move above the lifting storage platform. Push plate B flips down to a lower position, and the sliding table pushing mechanism pushes the sliding table to move above the small conveyor. Push plate B moves with the sliding table and pushes the top layer of cigarettes on the lifting storage platform onto the small conveyor. This process is used to remove cigarettes until the carton sealing machine is full. Then, the cigarette buffering device continues to buffer the cigarettes, while other conveyor branches feed the carton sealing machine. The cigarette buffering device installed on the conveyor branch uses the above method to remove the buffered cigarettes onto the small conveyor.

[0006] Furthermore, a cigarette bar front stop mechanism is installed on the frame. The cigarette bar front stop mechanism is used to block the cigarette bars on the small conveyor at the front end of the small conveyor, so that the cigarette bars are arranged statically on the small conveyor, making it convenient for the pusher plate A to push the cigarette bars to the lifting storage platform.

[0007] Furthermore, a cigarette pack back stop mechanism is installed on the frame. The cigarette pack back stop mechanism is used to block the cigarette packs from being transported on the small conveyor at the tail end of the small conveyor, so that no cigarette packs are transported on the small conveyor, making it convenient for the pusher plate B to push the cigarette packs onto the small conveyor.

[0008] This utility model discloses a cigarette pack conveying system for easy traceability of defective products. It includes multiple conveyor branches connected to the outlets of multiple packaging machines and a main conveyor bus connected to the inlet of a carton sealing machine. All conveyor branches converge onto the main conveyor bus. The system also includes cigarette pack buffering devices equal in number to the conveyor branches, with one buffering device installed on each conveyor branch. During carton sealing, each carton is fed to the sealing machine via only one conveyor branch. The remaining conveyor branches, when not feeding, buffer the cigarette packs, waiting for their turn to feed. The buffered cigarette packs are then fed together with the cigarette packs currently being conveyed. This ensures that the cigarette packs in each carton originate from only one packaging machine. If a defective pack of cigarettes is packaged by a fault, only the cartons containing the defective pack need to be located; it is not necessary to search each carton individually.
