Computer for controlling injection moulding system

Abstract

The invention provides an apparatus for controlling the injection moulding system having a plurality of devices executing injection moulding treatment and generating feedback signals, and a human machine interface having a display and at least one operator input device. The said apparatus comprises a first input / output for receiving command signals from said human machine interface manual input device, and for providing display signals to the human machine interface display; a second input / output for receiving the feedback signals directly from the plurality of injection moulding devices, and for providing real-time control signals directly to the plurality of injection moulding devices; and a CPU for generating the real-time control signals in accordance with said feedback signals and said command signals, said CPU performing multi-tasking processing of said command signals, said display signals, said feedback signals, and said control signals. A general purpose of the computer can resolve the problem of the real-time control of said injection moulding devices by plurality of processors.

Description

technical field [0001] The present invention relates generally to a computer for controlling an injection molding system, and more particularly to a computer for controlling a plurality of injection molding units having (i) performing an injection molding process and providing feedback signals, and (ii) having a display and at least one for The human-machine interface of the human-machine interface of the manual input device for inputting operator commands is controlled by the computer of the injection molding system. Background technique [0002] Injection molding systems are widely used to produce cheap plastic products such as plastic PET preforms that can be blown into various beverage containers that are common in daily life. Such injection molding systems typically include a variety of analog and digital components used to perform injection molding operations. For example, extruder drives, proportional flow control valves, electric drives, heating and cooling elements...

Problems solved by technology

In addition, the operating status of each injection molding system can only be confirmed through its HMI

Moreover, each injection molding machine manufacturer usually adopts its own patented design in its PLC, which will limit the application of various new processing technologies on such machines due to compatibility and other issues

In addition, the use of multi-layer structure of ASP and PLC processing control will have a negative impact on processing, and the resulting processing bottleneck will reduce the response speed of the machine to realize the corresponding state change
