[0034] The front end of the cigarette conveying mechanism in the conveying direction is connected to the rear end of the last layer of the first conveyor belt 1. The cigarette conveying mechanism includes a second conveyor belt 12 and a third conveyor belt 13. The second conveyor belt 12 has two layers, the upper and lower layers. The front end of the third conveyor belt 13 is connected to the rear end of the second conveyor belt 12.

[0035] In some embodiments, at least one group of support members 8 and first guide rods 9 are symmetrically provided on the left and right sides of the first conveyor belt 1, the bottom end of the support member 8 is connected to the frame of the first conveyor belt 1, and the upper end is connected to the first guide rod 9, and the length direction of the first guide rod 9 is consistent with the conveying direction of the first conveyor belt 1.

[0036] In some embodiments, five guide teeth 10 are evenly distributed on the periphery of the steering wheel 4 , and a side surface of each guide tooth 10 forms an angle of 72° with the same side surface of an adjacent guide tooth.

[0037] In some embodiments, the turning channel 5 includes a horizontal part and an arc-shaped part. The horizontal part is located at the rear end of the first conveyor belt 1 of the current layer, and the arc-shaped part surrounds the side of the turning wheel 4 away from the first conveyor belt 1. One end of the arc-shaped part is connected to the horizontal part, and the other end extends to the front end of the first conveyor belt 1 of the next layer.

[0038] In some embodiments, the first photoelectric sensor 6 is electrically connected to the controller of the second drive motor 3, and is used to start the second drive motor 3 when detecting the transported cigarette 16, so as to transfer the cigarette 16 to the first conveyor belt 1 of the next layer;

[0039] The second photoelectric sensor 7 is electrically connected to the controller of the first drive motor 2 and is used to start the first drive motor 2 when detecting the transported cigarette 16, so as to move the cigarette 16 along the transport direction of the first conveyor belt 1 on this layer.

[0040] In some embodiments, the first conveyor belt 1 includes at least two belt lines arranged side by side.

[0041] In some embodiments, a third photoelectric sensor 14 is provided between the rear end of the first conveyor belt 1 and the front end of the second conveyor belt 12 of the last layer, and a fourth photoelectric sensor 15 is provided between the rear end of the second conveyor belt 12 and the front end of the third conveyor belt 13.

[0042] In some embodiments, the cigarette conveying mechanism further includes a second guide rod and a third guide rod, the second guide rod is arranged on the left and right sides of the second conveyor belt 12 , and the third guide rod is arranged on the left and right sides of the third conveyor belt 13 .

[0043] In some embodiments, the third conveyor belt 13 is provided with a slope, and its rear end extends obliquely downward.

[0044] Specifically, the technical solution provided in the above embodiment utilizes the physical transmission principle to stack and convey the cigarette strips 16 by driving the conveyor belt through a motor. At the same time, the photoelectric sensor is combined to realize automatic control and monitoring to ensure the stability and accuracy of the whole process.

[0045] The operation process of the cigarette carton buffering equipment includes:

[0046] Cigarette stacking process:

[0047] The cigarette strip 16 is first placed on the first layer first conveyor belt 1. The first driving motor 2 of the first layer first conveyor belt 1 is started, and drives the first layer first conveyor belt 1 to move forward through the pulley block.

[0048] When the cigarette 16 reaches the rear end of the first conveyor belt 1 of the first layer, the steering mechanism starts to work. The second drive motor 3 of the first layer starts to drive the steering wheel 4 to rotate. The front of the cigarette 16 abuts against one side of the guide tooth 10, and the lower part of the cigarette 16 abuts against one side of the previous guide tooth 10. Under the rotation and guidance of the guide tooth 10, the cigarette 16 is transferred from the first conveyor belt 1 of the current layer to the first conveyor belt 1 of the next layer through the steering channel 5.

[0049] During the turning process, the first photoelectric sensor 6 detects the passing of the cigarette 16 and controls the second drive motor 3 of the current layer to start working until the cigarette 16 completely enters the conveyor belt of the next layer. At the same time, after the second photoelectric sensor 7 of the next layer detects that the cigarette 16 enters the first conveyor belt 1 of the next layer, it controls the first drive motor 2 of the previous layer to stop working and controls the first drive motor 2 of the current layer to start working.

[0050] In this way, the cigarette strips 16 are piled up layer by layer until the last layer of the first conveyor belt 1. The first conveyor belt can have three or more layers, and the more layers there are, the more cigarette strips 16 can be piled up and cached.

[0051] Cigarette conveying process:

[0052] When the cigarette cartons 16 on the last layer of the first conveyor belt 1 accumulate to a certain extent and need to be sorted, the cigarette cartons 16 begin to enter the cigarette carton conveying mechanism.

[0053] The cigarette strips 16 are first conveyed to the second conveyor belt 12, and then conveyed from the second conveyor belt 12 to the third conveyor belt 13. Since the third conveyor belt 13 is provided with a slope, the cigarette strips 16 can enter the next process more smoothly under the action of gravity.

[0054] During the entire conveying process, the second guide rod and the third guide rod play a guiding role to ensure that the cigarette strips 16 can be conveyed stably and accurately.

[0055] 3. Control and monitoring:

[0056] During the entire operation, the photoelectric sensor plays a key role. The first and second photoelectric sensors are used to control the turning and conveying of the cigarette strip 16, ensuring that the cigarette strip 16 can move along a preset path and speed.

[0057] The third and fourth photoelectric sensors are used to monitor the position and quantity of the cigarette strips 16 during the conveying process. Once an abnormality is detected, the machine can be immediately stopped for inspection to ensure the safe operation of the equipment.

[0058] 4. Security protection:

[0059] The equipment is also equipped with comprehensive safety protection devices, such as KEYENCE detection sensors, which are used to monitor the status of the equipment and cigarette cartons in real time. Once an abnormal situation is detected, such as a jam in the conveyor belt or excessive accumulation of cigarette cartons, the equipment will immediately stop and sound an alarm to ensure the safety of personnel and equipment.

[0060] In summary, compared with the existing technology, the cigarette strip caching equipment provided by the above technical solution, by setting up a multi-layer first conveyor belt, can temporarily cache the cigarette strips transported by the production and delivery ends on the first conveyor belt, and then transport them to the sorting line at the rear through the cigarette strip conveying mechanism when sorting is needed, avoiding the problem of interruption of the sorting line at the rear when the conveying flow rate of the cigarette strips is reduced.
