Research On Automatic Stacking And Packaging Production Line Of Aluminum Profile

As an important basic material in the building material industry,aluminum profiles are widely used in the construction and decoration industries due to their excellent properties that many other materials do not possess.The packaging of aluminum profiles is an essential part of the sales and transportation process.At present,most of aluminum manufacturers in China are still using manual ways to complete the stacking,wrapping and packaging of aluminum profiles.This kind of packing way has low efficiency and high labor intensity,and it is difficult to guarantee the quality and stability of packaging.With the rapid increase in the domestic demand for aluminum profiles,labor cost and the intensification of the survival of the fittest in the packaging industry,many enterprises need automatic packaging lines urgently,which can improve efficiency,quality and reduce labor cost.In this paper,under the full research and analysis of existing aluminum packaging process and industrial chain of an enterprise in Eastern China,and based on the enterprise's process requirements and technical indicators,an automatic stacking and packaging production line of aluminum profile was designed to realize automatic packaging of aluminum profiles.According to the requirements of the automation process and the characteristics of the existing industrial chain,the overall scheme and module layout of packaging production line were devised by the principle of modular design.Packaging production line includes two parts,mechanical structure design and control system design.The mechanical structure design part realizes the function of feeding of aluminum profiles,feeding and cutting of wrapping paper,wrapping and stacking of aluminum profiles,longitudinal packaging and discharging of aluminum profiles' stacking by designing corresponding functional modules.At the same time,detailed selection and verification of the actuators and standard parts of each module motor,cylinder,ball screw,etc.have been completed.For the control difficulties that the packaging production line has many power elements such as asynchronous motors and servo motors,the control system designed a PLC master-slave station control scheme based on PROFIBUS-DP for communication.At the same time,the controllers,pneumatic components,execution equipment,interactive equipment,position control equipment and communication equipment of the monitoring system were selected,and the pneumatic circuit,main circuit,signal circuit,communication configuration and control process were completed.Through the above methods,a control system is established in which the master-slave PLC station at various levels are used as a core controller,the touch screen is used as an interactive interface,cylinders and motors are used as actuator elements,and sensors are used as detection elements.In addition,this paper uses CAE simulation technology to simulate the mechanical system.Static and prestressed modal analysis of key components and potentially dangerous components are performed through ANSYS Workbench,and optimized solutions for individual hazardous areas are given.Moreover,the kinematics simulation analysis of the main functional modules is performed through Solidworks Motion.Through the above two methods,the mechanical performance and rationality of the structure are verified on the theoretical level.It also provides theoretical reference for prototype assembly and optimization of the mechanism.In addition,this paper carries out a confirmatory experiment on the packaging method,and further verifies the feasibility of the core process of the packaging production line from the actual production point of view.Finally,the paper summarizes the work of this project and puts forward the prospect of further optimization for the packaging production line.
