Propanol filling machine is driven by stepping motor to drop down to reach the lower limit position, the well is signaled by the travel switch, and the PLC controls the filling valve to open fully for filling. The use of local area network realizes the communication between the field computer and the equipment, through the RS485 network can communicate with the filling machine each other. The use of multiple filling machines can easily constitute a RS485 distributed control system network.
020-34563445Liquid Filling machine carries out image processing such as image filtering and edge detection through computer, and finally rejects unqualified products by controlling the actuator through programmable controller. Through the photoelectric sensor triggers the camera to collect, the collected information will be transmitted to the image processing module, the image processing module through the image denoising, image enhancement, image segmentation and other algorithms to process the collected images, and finally according to the judgment results of the signals will be transmitted to the PLC, the PLC according to the information on the rejection mechanism for control.
Filling system mainly includes image acquisition module, image processing module, computer system intelligent processing module and control output of four major components. Analog-to-digital converter (ADC) converts the image information output from the camera into a digital image and stores the image in the SRAM by the CPLD, the SRAM is linked to the DSP, and the image is processed by the DSP in the later stage; after the DSP finishes processing the image, the final result is outputted through the serial port and the general-purpose input and output port.
Image acquisition module: the selection of optical equipment needs to consider the transparency of the target performance, production line vibration and background environmental changes and other issues, the choice of image acquisition equipment should be able to adapt to changes in the light of the production environment and production line speed adjustment. Light source selection of long life, low power consumption, radiation-free LED light source image processing module: image processing module is the use of one or more digital signal processor DSP for high-speed computing, the collected images for denoising, edging, and a series of complex processing such as image enhancement.
