The Control System Design Of Corrugated Box Production Line Based On S7-1500 PLC

With the rapid development of China's express package industry,the use rate of corrugated carton packing is getting higher and higher.Traditional corrugated carton production equipment is mainly suitable for mass production.It is necessary to adjust the equipment in advance when changing the box shape and size,and the production of cardboard corners waste more.It is imperative to improve the performance of corrugated box production equipment from the aspects of saving production resources and improving production efficiency.According to the current market corrugated box production can not achieve small batch flexible customization.This paper designs and develops a set of automatic production line control system of corrugated carton based on PLC.The designed production line system has excellent performance,which can flexibly realize the customization of large and small batches of single carton.Moreover,the utilization ratio of corrugated cardboard materials has also been improved,which improves the production efficiency and reduces the labor cost.The thesis mainly completes the following parts of work:(1)The problems of corrugated carton production equipment are analyzed.A new processing technology is designed,and the overall structure of corrugated carton production equipment is improved.Higher precision components are selected in the hardware configuration of the equipment.On the system control,the programming method is more reliable in practice.The designed production line to a certain extent solves the contradiction between the production equipment of corrugated carton and the actual demand.(2)Lower computer control and upper computer monitoring are the core parts of the production line control system.The actuator part of the lower machine adopts Siemens new generation s7-1500 PLC controller as the control core.ET200 MP is used as distributed I/O,and Siemens servo is used as the driving unit.TIA Portal V15 was selected as the unified software development platform designed by the upper computer.WinCC which is integrated in TIA Portal V15 is sued to design the human-computer interaction interface.(3)Tests on the actual system of the device.The equipment runs stably,the size of the production carton is relatively accurate,the incision is neat,the indentation is clear and the line does not collapse.The operation stability of corrugated carton automaticproduction equipment can meet the requirements.Increased production efficiency,and reduce the waste of production materials,and can achieve small quantities of flexible customization carton demand.
