Control method for electromagnetic iron nail packaging equipment

The invention relates to a control method of electromagnetic nail packing complete equipment, which consists of a control principle, a parallel logic control and a control sub-process, wherein, magnetized nail sorting is used as a main control sub-process and a feeding and weighing sub-process is an independent closed loop sub-process and a condition parallel sub-process which has logical associations in time sequence, and comprises a large hopper independent closed loop parallel control sub-process, a third class feeding independent closed loop parallel control sub-process, a baiting condition parallel control sub-process, an aneroid capsule positioning condition parallel control sub-process, a parallel control sub-process for the positioning condition of the aneroid capsule to a magnetized position, a hoisting hopper ascending condition parallel control sub-process, a hoisting hopper descending condition parallel control sub-process and a magnetized nail sorting body parallel control sub-process, etc. The control method ensures that packing time is shortened essentially equal to the time consumed by the magnetized nail sorting, thus improving the work efficiency and the reliability as well as being easy for programming and having simple maintenance.
