In SC series PLC application in the enema machine control system

Pick to: SC series PLC is a newly launched a series of PLC controller S, main is to increase the total bandwidth is 130 k of high-speed pulse output and high-speed count function suitable for control of servo system, this project use SC series PLC for the customer to develop a set of system, system of DOP - for touch screen DVP - A57GSTD + programmable controller Sc11t + servo ASD - 12 A021LA, the whole system because of high control precision, thus involving debugging precision measures described in this paper. Key words: food machinery sausage filler touch screen PLC servo 1 introduction sausage filler project belongs to the food machine control system. System consists of touch screen, PLC controller, servo, etc. Sausage filler are the main functions of the intestinal material accurate quantitative pouring into the casing, and then around the bowel in accordance with requirements. The whole equipment control are the main requirements to perfusion is accurate. The intestine is mixed with air bubbles in the material, and there is no way to remove temporarily, so finally the equipment is by setting deviation methods to adjust deviation, but because of mechanical institutions match problem, when debugging after many software and hardware improvement finally reached the requirements of reach the use requirement. System design 2. 1 process control principle of the design project belongs to the system of mechanical equipment, require high precision, the technological process is relatively complicated. Main requirements are as follows: by setting different class of bowel, can processing three kinds of specifications of the products; Request the actual deviation shall not be more than + / - 5 g; Requirements can be set manually and automatically run to run; For servo speed can be adjust continuously; Deviation adjustment function, and display the fine-tuning value; Equipment work indicated in figure 1. Touch screen is mainly used to display and control, set the weight and gathering data fine-tuning, production records, etc. ; PLC is mainly to collect data and calculate, control the servo motor and rotary motor actions; The role of the servo motor is used to make rotation feeder accurate quantitative. （ 1) The function of the system requirements: servo speed can be set, so that you can adjust the product processing speed; Can set the output to control the production of the specifications of the products; Set reverse motor turns; With functions of deviation fine-tuning, and display the fine-tuning value; According to the different intestinal material set processing different class sausage; Can achieve continuous operation and some functions. （ 2) The key technology. One of the most important functions in the above functions implementation is different grades of control of the sausage, which is the most difficult part, because of the different grade of the sausage intestines material is different, the proportion of different intestinal material is different, so the equipment to the output of the same weight of product rotary feeder turn laps is different, through the study of the experiment of different intestinal material, statistics of different bowel corresponding servo revolution, finally got through several rounds of test technology needed for quantitative data, but also to find the general test measurement data error correction. Figure 1 sign for 2 equipment work. Two systems of size: 6 digital quantity input; Three digital output; A servo control. Control system configuration: touch screen: DOPA57GSTD; PLC：DVP12SC11T； Servo: ASD - A021LA； Position detection: proximity switch. 2. 3 software architecture system software is divided into two parts: the part HMI and PLC. （ 1) HMI is part of the main frame: home page; Control the picture; Parameter Settings. （ 2) The PLC controller part main frame: servo speed setting; Operation mode control; The distinction between the different product process data. 2. 4 system debugging debugging steps and matters needing attention include: through repeated trials get value: determine the three grade product unit weight of the required number of pulses; About of the deviation value is obtained by trial and error; In the debugging of the need to pay attention to the speed of the enema, because different speed may have different amount of air into the influence the accuracy of the weight of the intestine; 3 conclusion system used in the SC series of PLC to the console of servo system, achieved the use requirement. Project USES a series of mechanical and electronic products, system integration performance reflects the overall cost of a single automation platform optimization efficiency advantages.
