[0002] In the automated processing process of tobacco products, after cigarette rods complete processes such as filter tip attaching and weight detection, continuous cigarette rod segments often need to be cut into unit segments of specific lengths according to subsequent process requirements (such as packaging specifications, quality sorting, etc.). The cut cigarette rod segments need to enter the next process in an orderly single-cigarette posture to avoid equipment jams, detection errors or packaging defects caused by multi-cigarette stacking, tilting or disorderly arrangement.

[0003] Currently, cigarette rod conveying devices mainly rely on negative pressure adsorption or mechanical grippers to achieve the grasping and releasing of workpieces. The negative pressure system controls the opening and closing of the negative pressure source through solenoid valves, and the mechanical grippers rely on cylinders or servo motors to drive the clamping and releasing actions. In the above methods, dedicated driving components and sensors need to be configured to achieve precise control, which not only increases the cost, but also the control algorithm needs to coordinate the timing of grasping and releasing, resulting in complex control.

[0057] Further, this embodiment also provides a cigarette conveying method, which is applied to the input drum device. Referring to Figure 5 , it includes the following steps:

[0058] S1. The radial projection area of the first air hole 2111 overlaps or is misaligned with the radial projection area of the second air hole 2121 to form a ventilation range. The first mounting hole 2311 is located within the ventilation range, and the input suction nozzle 232 adsorbs the workpiece at the input station;

[0059] S2. The driving assembly 30 drives the mounting disk 231 to rotate. The mounting disk 231 drives the input suction nozzle 232 to gradually approach the handover station.

[0060] S3. The first mounting hole 2311 is completely misaligned with the ventilation range, and the input suction nozzle 232 releases the workpiece at the handover station.

[0061] By rotating the mounting disk 231, the first mounting hole 2311 is controlled to enter or leave the ventilation range, so that the input suction nozzle 232 can adsorb and release the workpiece at different stations, avoiding the need to additionally set control components, improving the simplicity of cigarette conveying, and reducing the cost of cigarette conveying.
