Description

Technical Field

[0001] This utility model relates to the technical field of diversion and anti-jamming devices, specifically a diversion and anti-jamming device for cigarette packing machines. Background Technology

[0002] In automated cigarette production lines, efficient diversion is a core element in ensuring the continuous and stable operation of the production line, particularly in the final processing stage of cigarette cartons. With increasing automation, modern production lines now operate at speeds of 300-600 cartons per minute, placing extremely high demands on the accuracy and smoothness of diversion. Currently, after cartons of cigarettes are conveyed to the diversion area via the main conveyor line, they are distributed to multiple branch lines by the diversion mechanism. However, high-speed conveying can easily lead to jams due to various factors. This manifests as cartons of cigarettes accumulating, jamming, or being squeezed at the intersection of the main and branch lines, causing production line shutdowns, loss of diversion efficiency, and damage to cigarette packaging and equipment wear. The core causes of jamming include: uneven arrangement of cartons of cigarettes due to conveying fluctuations, excessively small spacing, and the diversion mechanism not having enough time to complete its action before the next carton arrives, resulting in multiple cartons of cigarettes entering the branch line simultaneously and causing jamming.

[0003] Therefore, this utility model provides a cigarette packing machine cigarette diversion and anti-jamming device. Utility Model Content

Two anti-jamming levers are provided between the main conveyor and the connecting conveyor. A fixed guide plate is provided on one side of the connecting conveyor, with one end of the fixed guide plate installed inside the main conveyor to guide the cigarette packs into the connecting conveyor. Both the main conveyor and the fixed guide plate have clearance slots on their side walls, located at the intersection of the main conveyor and the connecting conveyor. Anti-jamming levers are rotatably connected to the inner walls of both clearance slots. The two anti-jamming levers rotate alternately without contacting each other.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 The cigarette packaging machine includes a cigarette diversion and anti-jamming device, comprising a main conveyor 1, a connecting conveyor 11, and a diversion conveyor 12. Two anti-jamming levers 2 are provided between the main conveyor 1 and the connecting conveyor 11. A fixed guide plate 13 is provided on one side of the connecting conveyor 11. One end of the fixed guide plate 13 is installed inside the main conveyor 1 to guide the cigarette packs into the connecting conveyor 11. Both the main conveyor 1 and the fixed guide plate 13 have clearance strip holes 14 on one side and the side wall of the fixed guide plate 13. The two clearance strip holes 14 are located at the intersection between the main conveyor 1 and the connecting conveyor 11. The inner walls of the two clearance strip holes 14 are rotatably connected to the anti-jamming levers 2. The two anti-jamming levers 2 rotate alternately without contacting each other. The main conveyor 1 and the diversion conveyor 12 have the same conveying speed, and the conveying speed of the connecting conveyor 11 is 1.5 times that of the main conveyor 1.

[0016] It should be noted that, as described in this embodiment, the speed difference between the connecting conveyor 11 and the main conveyor 1 facilitates the separation of two cigarette packs that are relatively close to each other at the intersection of the connecting conveyor 11 and the main conveyor 1, thereby increasing the distance between them.

[0017] Specifically, the main conveyor 1 is responsible for transporting the cigarette packs to the diversion area. A fixed guide plate 13 is installed at one end inside the main conveyor 1 and extends to the connecting conveyor 11 at the other end, precisely guiding the cigarette packs from the main conveyor 1 to the connecting conveyor 11. Two anti-jamming levers 2, rotatably connected within the two clearance slots 14 at the intersection of the main conveyor 1 and the connecting conveyor 11, operate when cigarette packs overlap, but do not activate when a single cigarette pack passes through. The two anti-jamming levers 2 dynamically sort the cigarette packs entering the intersection by alternating rotation without contacting each other, preventing the cigarette packs from overlapping at this point. Simultaneously, the device employs a differentiated speed design: the main conveyor 1 and the diversion conveyor 12 maintain the same conveying speed, while the connecting conveyor 11's conveying speed is 1.5 times that of the main conveyor 1. When cigarette packs pass from the main conveyor 1... When the cigarette packs enter the connecting conveyor 11, the speed difference quickly separates the packs that were originally too close together, allowing sufficient time for the subsequent diversion mechanism to operate. This effectively solves the problem of uneven arrangement and jamming caused by uneven spacing of cigarette packs due to fluctuations in the conveying process. The speed difference between the connecting conveyor 11 and the main conveyor 1 can effectively separate closely spaced cigarette packs, preventing multiple cigarette packs from entering the branch line at the same time and causing compression. The alternating action of the anti-jamming lever 2 actively intervenes in any jamming that may occur at the junction, and with the precise guidance of the fixed guide plate 13, it prevents cigarette packs from accumulating or getting stuck at the junction of the main and branch lines. By reducing jamming, the probability of production line downtime is reduced, the diversion efficiency is improved, and damage to cigarette pack packaging due to compression is avoided. At the same time, wear and tear on the equipment caused by jamming is reduced, ensuring the continuous and stable operation of the high-speed production line.

[0018] In one embodiment of this utility model, such as Figures 1-4 As shown, a connecting plate 3 is installed inside the diversion conveyor 12. The top of the connecting plate 3 is flush with the upper surface of the conveyor belt in the connecting conveyor 11 and the diversion conveyor 12. A movable diversion guide mechanism 31 is installed on the top of the connecting plate 3. The movable diversion guide mechanism 31 swings back and forth in the horizontal direction at the top of the connecting plate 3.

[0019] It should be noted that the bottom of the connecting plate 3 described in this embodiment is equipped with a motor that drives the movable diversion guide mechanism 31.

[0020] Specifically, the top of the connecting plate 3 installed inside the diversion conveyor 12 is flush with the upper surface of the conveyor belt in the connecting conveyor 11 and the diversion conveyor 12, ensuring a smooth transition of the cigarette packs from the connecting conveyor 11 to the diversion conveyor 12 and avoiding jamming of the cigarette packs due to height difference; the movable diversion guide mechanism 31 at the top of the connecting plate 3 swings back and forth in the horizontal direction at its top, driven by the motor installed at the bottom of the connecting plate 3, and can adjust the guide direction in real time according to the diversion requirements, accurately guiding the cigarette packs into the corresponding channel of the diversion conveyor 12.

[0021] In one embodiment of this utility model, such as Figures 1-4As shown, a U-shaped support frame 4 is installed on the top of the main conveyor 1, and a movable industrial camera 41 is installed on the side wall of the U-shaped support frame 4. The movable industrial camera 41 is located above the two anti-jamming levers 2.

[0022] It should be noted that the U-shaped support frame 4 described in this embodiment is used to adjust the angle of the movable industrial camera 41 by a motor on one side.

[0023] Specifically, the U-shaped support frame 4 installed on top of the main conveyor 1 provides stable support for the movable industrial camera 41. The movable industrial camera 41 is positioned above the two anti-jamming levers 2, and the U-shaped support frame 4 drives the movable industrial camera 41 to adjust its angle via a motor on one side, enabling it to accurately capture the state of the cigarette strips passing below. During operation, the movable industrial camera 41 collects image information in real time, such as the spacing, arrangement posture, and whether the cigarette strips are skewed or overlapping, providing a basis for subsequent control. Through the dynamic angle adjustment and precise shooting of the movable industrial camera 41, it is possible to promptly detect... Issues such as insufficient spacing or abnormal arrangement of cigarette packs before they reach the anti-jamming lever 2 are addressed by providing signal support in advance for the action of the anti-jamming lever 2 and the speed control of the connecting conveyor 11, enabling the equipment to more proactively address potential jamming risks. Compared to traditional sensors, industrial cameras offer more accurate image recognition, capable of identifying more complex cigarette pack states, reducing jamming caused by detection errors, improving the ability to predict cigarette pack states, further reducing the probability of cigarette packs accumulating or being squeezed during the diversion process, reducing production line downtime, lowering the risk of packaging damage and equipment wear, and ensuring the efficient and stable operation of the production line.

[0024] In one embodiment of this utility model, such as Figures 1-4 As shown, both ends of the two anti-jamming levers 2 are provided with notches 21, and rollers 22 are rotatably connected to the inner wall of the notches 21.

[0025] Specifically, when the anti-jamming lever 2 rotates alternately to adjust the cigarette pack, the roller 22 directly contacts the surface of the cigarette pack. Through its own rotation, the sliding friction between the lever and the cigarette pack is converted into rolling friction, reducing frictional damage to the cigarette pack packaging. At the same time, the rotation of the roller 22 can push or guide the cigarette pack more smoothly, avoiding the cigarette pack from tilting or getting stuck due to excessive friction between the lever and the cigarette pack, ensuring that the lever is more efficient and stable when adjusting the position and posture of the cigarette pack.

[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, each of the two anti-jamming levers 2 has a drive unit 23 at its top, and the two drive units 23 are respectively installed on the top of the main conveyor 1 and the fixed guide plate 13.

[0027] It should be noted that the drive unit 23 described in this embodiment is a drive motor.

[0028] Specifically, the drive unit 23 provides power for the rotation of the anti-jamming lever 2. During operation, the two drive units 23 independently drive the corresponding anti-jamming lever 2. The rotation angle, speed and timing of the lever are precisely controlled according to the cigarette conveying status. Through active and controllable lever power and action rhythm, the cigarettes at the junction of the main conveyor 1 and the connecting conveyor 11 are effectively sorted and adjusted to ensure that the cigarettes enter the connecting conveyor 11 smoothly. This avoids sorting failure caused by insufficient lever power or poor action coordination, and further ensures the anti-jamming effect.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] Working principle: The main conveyor 1 transports cigarette packs to the diversion area. The fixed guide plate 13 guides the cigarette packs to the connecting conveyor 11. The main conveyor 1 and the diversion conveyor 12 have the same speed, while the connecting conveyor 11 has a speed 1.5 times that of the main conveyor 1. The speed difference is used to separate cigarette packs with too small a gap. The anti-jamming lever 2 at the intersection of the main conveyor 1 and the connecting conveyor 11 is driven by the drive unit 23. It rotates alternately only when the cigarette packs overlap, so that the cigarette packs in front pass first, and the cigarette packs behind pass slightly later after being intercepted. The rollers 22 in the notches 21 at both ends reduce the damage to the cigarette packs through rolling friction. The movable industrial camera 41 on the U-shaped support frame 4 can be adjusted in angle to collect the status of the cigarette packs in real time, providing signals for the lever action and speed control. The top of the connecting plate 3 inside the diversion conveyor 12 is flush with the conveyor belt. The movable diversion guide mechanism 31 at the top is driven by a motor to swing horizontally, accurately guiding the cigarette packs into the corresponding channels. The whole process achieves smooth diversion of cigarette packs and prevents jamming.
