The central conveying system is an efficient and intelligent material transmission equipment, which is widely used in injection molding, extrusion, blow molding and other plastic production industries. It can automatically transfer raw materials from the storage warehouse to the production line, avoiding the problems of manual intervention and material waste, and improving production efficiency and quality. The control mode and control process of the Centralized feeding system are the key parts.
Control mode of central feeding system
The control mode of the Injection molding centralized feeding system is mainly divided into two types, one is PLC control mode, and the other is PC control mode. The PLC control method is to pre-program the control program and then execute it automatically through the PLC program. The PC control method is to write the control program on the computer and control it through software.
For the PLC control method, it can realize the automatic control of the system and improve the production efficiency and quality. At the same time, the programming method of the PLC control system is simple, easy to learn and understand, and can reduce maintenance costs. In the PLC control system, there are two main parts: the program and the controller. The program is the instruction set in the control system, and the controller is the device that executes the program. Usually, the PLC controller uses digital input and output to realize the control of the control system, and controls the various equipment of the Injection molding central feeding system through the output signal in the controller.
In the PC control mode, the connection between the computer and the central feeding system is realized through the Ethernet protocol. When connecting we need to make sure that the IP address is configured correctly. In addition, in the PC control system, the programming language used is very diverse and can be selected according to the actual application. On this basis, we can adopt various control algorithms to optimize the control system.
