Haichen Industrial Control——Fully Automatic Centrifugal Casting of Nylon Tubes

Mainly composed of robots and their track systems, nylon tube centrifugal mold frames and molds, circulating oven conveyor systems, casting feeding systems, demolding unloading systems, and automation control systems.

The linear production line is arranged in a horizontal ground linear structure. The robot moves back and forth along the track in a linear motion, controlled by a PLC program for precise positioning to ensure accurate robot operation.

The electrical control system consists of Siemens PLC1513+V90+G120+1200+TP900. The main CPU, controlled by Siemens 1513, manages four sets of V90 servo motors. The track system schedules the robot track V90 motor using position control mode and configures the 105 message to the TO process object; the casting feeding system and demolding unloading system's cap screwing function use torque control, speed control, and position control to complete the entire cap screwing process, configured with 105 message plus 750 additional message to the T0 process object.

The main PLC1513 communicates unilaterally with the slave station 1200 using the Siemens S7 protocol. The host intelligently cycles to schedule the processing tasks of each mold frame; the slave station 1200 controls the speed of the V90 centrifugal motor using message 1 for precise speed control; the integrated PID automatic adjustment function of the 1200 controls the temperature of each mold frame.

The entire production line can operate fully automatically, unattended, and intelligently. Products can be recorded, quality can be traced, and data visualized, which not only improves production efficiency but also ensures more stable product performance.
