An airflow‐induced separation method for stacked paper labels is proposed with a stream of compressed air used to jet vertically onto the side of the stacked labels and force constraints applied to the two ends of the labels. Its mechanism is revealed that the viscous force caused by airflow is the main driving force for the initial separation of labels and the vertical force is the main factor for the formation of successive separation channels. Theoretical and experimental analyses are implemented to ensure the effects of airflow velocity, label characteristics, label stress, and other factors on label separation and show that a stable separation gap can be generated with separation efficiency of more than 3600 sheets per minute and reliability of 99.99%. A complete airflow‐induced label separation device is designed, which can be integrated into the existing packaging machine, and the physical feasibility of the stack label separation method is verified by experiments.

Laser printer internal parts are prone to deformation when they are working in high temperature environment for a long time, resulting in machine faults such as paper jam and angle folding. In order to predict the deformation of parts in thermal environment and further determine their initial allowable deformation, so as to guide the structural design and production process of parts, and to reasonably determine the stress mode of parts in the working process, the structural deformation of the complex injection part-fuser upper cover in a laser printer after long-term operation in thermal environment is studied. First, on the basis of fusing temperature control technology and heat exchange analysis of the whole machine, the internal temperature field of a laser printer is numerically simulated by using the flow and heat transfer analysis software, and the temperature data of the key parts inside the machine are obtained more accurately. Then, the sequential coupling method is used to apply the results of thermal analysis of the whole machine as the external loads of static stress analysis to the fuser upper cover model, and the structural thermal deformation data of the fuser upper cover are obtained.

Purpose The purpose of this paper is to investigate the mechanism of sheets ply separation induced by air flow through numerical simulation with two-way FSI (fluid-structure interaction) simulation using ANSYS and theoretical speculation. Design/methodology/approach The paper primarily establishes a simplified physical model of the sheets ply separation induced by air flow. Then, the force of the air flow acting on the sheet has been analyzed based on the model, and the main factor leading to separation was obtained. Furthermore, the parameter analysis was investigated based on linear stability analysis, from which the factors that affect stable separation are obtained. Finally, a series of numerical simulations are performed to verify the conclusions. Findings This study shows that the main separation factor is the variable air pressure in the gap between the sheets caused by the dynamic pressure air flow. Increasing the inlet velocity of the flow field will increase the separation distance but excessive velocity will lead to instability. The viscous resistance acting on the sheet and the bending stiffness of the sheet are factors that stabilize the system, and the sheet density and the restoring force can lead to instability. Originality/value The paper is one of the first in the literature that investigates the problem of sheets ply separation induced by air flow, which is the primary method for multi-layer separation in sheets de-stacking operations, especially for the high-speed occasion.
