Problems solved by technology

For large and medium-sized injection molding machines, the transmission distance between the analog signal acquisition point and the controller is relatively long, and the long-distance transmission of analog signals is extremely susceptible to interference. In the injection molding machine control system, the electronic ruler and temperature signal collected by the controller have large errors, and the control accuracy of the injection molding machine is difficult to guarantee

Abstract

The invention discloses an injection moulding machine control system based on function adapter line boxes with CPUs (central processing units). The control system comprises the plurality of function adapter line boxes with the CPUs, wherein the adapter line boxes are mounted in different places far away from a central main controller of an injection moulding machine and form the injection moulding machine control system together with the central main controller; and the function adapter line boxes with the CPUs comprise an analog signal collection adapter line box, an analog signal output adapter line box, a temperature signal collection adapter line box, a heating output adapter line box and a digital signal input and output adapter line box. According to the control system, different signals are regionally and intensively collected and output, so that the quantity of cables connected among sensors, actuators and the main controller can be greatly reduced. Meanwhile, as the adapter line boxes communicate with the main controller by adopting a serial bus, the IO (input output) expansion is easy.

Description

technical field [0001] The invention belongs to the technical field of injection molding machine controllers, and in particular relates to a function transfer junction box with a CPU and a main controller to form an injection molding machine control system. Background technique [0002] Traditional injection molding machine controllers adopt centralized control and distributed wiring. The electrical signals from all parts of the body are connected to the controller one by one through cables, such as image 3 shown. According to the physical location of the signal distribution, considering the length limit of the sensor leads and the convenience of installation and repair, most of the signals will be connected to the controller through the terminal box, as shown in the terminal box in the figure, and some signals that are closer to the controller are directly connected to the controller. To the controller, the number of cables used corresponds to the number of signals. The c...
