Improvement Of YP13 Palletizer Structure And Dynamics Simulation Analysis Of Cam Mechanism

Palletizer is the core of cigarette packaging equipment,its performance determines the capacity of cigarette packaging.With the continuous development of industrial technology,enterprise equipment also needs to be constantly improved and upgraded to ensure the competitiveness of enterprises.Due to the expansion of the production scale of enterprises,new packaging process production lines need to be added on the basis of retaining the original production lines.Enterprises need to improve the structure of existing YP13 palletizer,and then apply it to the new production line.The new technological requirements are as follows: 1)simplify the original structure of palletizer as much as possible and make it easy for palletizer to process,manufacture and maintain;2)change the number of cigarettes lifted once from 6 to 5,and keep the maximum number of palletizer layers unchanged;3)ensure the original lifting height of the palletizer is 65 mm,the opening and closing angle is 4.6 degrees;4)under the premise of 5 cigarettes being transported to the position time is 1.74s;It can meet the stacking capacity of at least 120 bars/min.Firstly,the structure of palletizer is improved.This paper analyses the structure and principle of YP13 stacker,determines the parts that need to be improved,and then designs the parts that need to be improved.Finally,the three-dimensional structure of palletizer is modeled by Solid Edge ST8.Secondly,the dynamic simulation analysis software ADAMS is used to simulate and analyze the cam mechanism of the palletizer to verify whether the working performance of the palletizer meets the improvement requirements;verify whether the core working mechanism of the palletizer,the cam mechanism,meets the working intensity,and provide reference for the optimization of the cam.In order to facilitate the installation and transportation of equipment,the base with the largest mass and volume of parts is selected for lightweight design.The strength of the base is verified by static analysis in ANSYS/workbench,the natural frequency of the base is obtained by modal analysis,and the resonance with the working frequency of the spindle is verified to prepare for the optimization of the base.Using the topology optimization module to lighten the base,the model of the base is reconstructed according to the results of optimization,and then the reconstructed model is validated.Finally,the prototype is manufactured.The improved palletizer is used to generate engineering drawings by three-dimensional software,and each part is processed and manufactured according to the drawings.After manufacturing,the parts are assembled,and finally the palletizer is tested.
