The work aims to design and implement an automatic bobbin bagging system for bobbin bag package with Siemens PLC S7-1200 as controller according to the technological requirements of bobbin bag package in textile enterprises, so as to improve the packaging efficiency. In terms of the mechanical structure design of the system, the subsystems of bag-feeding and bagging were designed, and each subsystem was composed of several mechanical devices. In terms of the control system, the hardware and software of the control system were designed, which were controlled by programmable logic controller (PLC), and actuated by DC motor, cylinder solenoid valve and vacuum sucker, etc., and configured by Siemens touch screen to realize the monitoring of the production process and the switch of manual automatic mode. The prototype stability test was carried out in 10 groups for 100 times in each group. The results showed that the operation was relatively stable and the success rate reached 99.3%. The overall operation of the system is stable, and the packaging efficiency has been greatly improved compared with manual operation.
