Rice cake continuous vacuum
packaging machine programmable control programming method.
Rice cake for vacuum
packing machine is a automatic vacuum packaging machine, also known as rice cakes stretch film packaging machine, its operating system is controlled by programmable control system, the same hardware system, if designed by different people, can design the different application, some design program simple, and reliable, and design program, although some people can complete the task, but more complex and PLC program design is to have rules to follow, the following will introduce two methods: the experience design method and the flow chart design method.
a flowchart design method,
rice cakes continuous vacuum packaging machine programmable control programming method.
Flow chart of stretch film packaging machine is sequence function diagram, flowchart design method is to draw the flow chart according to the requirements of the system control, according to cheng pictures ladder diagram, ladder diagram can be basic instructions ladder diagram, can also be a step ladder diagram and the function instructions ladder diagram as a result, the design flow chart is the key to the whole process.
1, according to the basic method of ladder diagram process picture
rice cakes continuous vacuum packaging machine programmable control programming method.
Stretch film vacuum packaging machine ladder diagram need to design proper flow chart according to control requirements, and then write the correct Boolean expression, and then draw basic instructions ladder diagram.
2, according to the process drawing step ladder diagram method
rice cakes continuous vacuum packaging machine programmable control programming method.
Stretch film vacuum packaging machine order flow chart and step ladder diagram has a one-to-one relationship.
3, according to the flow chart of use function instruction of ladder diagram method
rice cakes continuous vacuum packaging machine programmable control programming method.
The succession of the tensile membrane vacuum packaging machine instruction shift instruction & other;
SFTL”
And & other
SFTR”
Very suitable for sequence control.
2, experience design method
rice cakes continuous vacuum packaging machine programmable control programming method.
Rice cake continuous stretch film packaging machine experience design method is based on some typical ladder diagram, according to the specific object of the control system of the specific requirements, to modify and improve the original ladder diagram.
This method is suitable for the people has the work experience, these people have a ready-made material, particularly in product upgrades, save time by using this method.
it introduces two common rice cake continuous vacuum packaging machine of programmable control programming method, and in the process of programming, need according to the customer the product packaging and the actual experience of programming, rice cake continuous vacuum
packing machine is a large fully automatic vacuum packaging machine, on the choice of the early, need to all-round, choose experienced enterprise, so the late late in both the use and maintenance, not only will enhance the effect and cost savings for the enterprise!
