The application of PLC in the vacuum packaging machine

The application of PLC in the vacuum packaging machine newmaker welcome to e hall hall 2 vacuum/air/shrinkable packaging machinery exhibition hall vacuum packaging machine, gas switch machine, blister packing machine, shrink packaging machines,. 。 。 Vacuum packaging machine, mainly used to make the packing bag of toys, hardware, instruments, and other products. The equipment control circuit adopts the traditional relay control, complex operation, finalize the design time, mold temperature is not stable, drift. Internal wiring of control cabinet is complex, equipment maintenance and troubleshooting to bring very great inconvenience. The factory to prepare for this to modify the equipment. Project is introduced in the production of packaging bags, molding temperature and heating, cooling time is a very important link, the calls from the stable temperature, heating, cooling, according to the time can be set and the forming time to be able to store a variety of different products. 1. One solution for this situation, the plant in the process of equipment modification using PLC and touch screen as the core controller. FBS series PLC with its small size, high reliability, NC precision positioning, communication characteristics such as powerful function, has been widely used in industrial control field. 2. 2 the hardware configuration of the FBS - in this paper 32 ma for molding machine in the process of heating plate of the heating time, forming time and cooling time setting and display monitor, and different mold production process time needed for storage and in the process of calls, automate the molding machine. Core of the operation of the control system adopts touch screen, the control part adopts FBS - 32 ma, the controlled object by tube, cylinder and the motor. Performance control system are as follows: 1. 3 general model 1. 4 process introduction part of the implementation of temperature control, forming machine of the heating system is composed of six groups of heating tube, by the thermostat and solid state relay to control. According to the needs of the control process of PLC, cooperate with other function modules, flexible combination, can achieve a variety of control requirements. Single host can realize 32 temperature measurement of the road, and there are the most commonly used thermocouple and 2 broad categories, a total of 5 kinds of platinum resistance temperature module, select eight eat transistor output of TC6 and temperature acquisition module, through temperature PID control command FUN: TPCTL machine to implement of the constant temperature control. PID temperature control module with temperature programming of the utilizing form will machine the current temperature of the heating disc comparing with set point, ON the basis of existing deviation, via software PID algorithm, mathematics, computing the results into a time scale ON/OFF ( Pulse width modulation) , driven by the transistor output point output control SSR heating loop, keeping the temperature of the heating disc in the SV + / - 1 ℃. 1. 5 the software design, 1) Temperature acquisition by the temperature of TC module to implement the plan form, the following figure: ( 2) Program by using TPCTL instructions to complete, temperature setting, various P, I, D are set: (through the screen 3) In the process of PLC to the internal P, I, D have default parameters, can according to need to modify: 4) Relevant time setting different model requires different molding time, so I need PLC modifications to the time of different models. Can I take a picture to set and call. For equipment braking time, aeration time, encapsulation and smoke heat sealing, etc.  Can be set according to the actual situation, make the application more flexible. The function by the internal registers with touch screen and PLC. Equipment debugging the equipment technical difficulties is to ensure that equipment, debugging, finalize the design time, and mold temperature precision, prevent drift. According to the actual situation of program fine tuning their value to compensate value, make temperature meet the requirements of accuracy, equipment action is more rigorous. 2. 1 effect after the complete system, which controls the equipment get more humanized operation, improves the automation. Figure 4 - 1 the whole equipment in figure 2. 2 application experience the equipment after the transformation, has been put into production. In the practical production shows that FBS affordable hosting FBS - series 32 ma has a good cost performance, powerful function, can fully meet the requirements of the original renovation. Temperature can maintain in the SV + / - 1 ℃, finalize the design time, and can store about 99 groups of different molding parameters of product, call convenient, greatly improving the product quality and production. Summarize all visible, FBS series host performance is remarkable, stable and reliable, easy to operate features in this case most profound experience. High performance to price ratio.  In this case reflect incisively and vividly, a convincing performance. Relying on its excellent quality and high cost performance, PLC controller has been more and more manufacturers in the industry recognition.
