LT touch screen Pro-face integrated PLC function applications in injection molding machine

Children's toys, lego toy and what car radio LT screen injection applications Pro-face button LT screen injection applications Pro-face has a similar place? On the similarities in their production: model casting. Usually, we won't go to care about used in daily life is how to produce similar products. However, we will use these commodities countless times every day, whether we car remote control locks, mobile phone or a printed with company logo pencil, even some very old spring connector is cast into the model.

Erwin Quarder Werkzeug GmbH is a veteran in the field of the producers. The company producing all kinds of industrial plastic particular research material, to Espelkamp north bank of the Rhine river/Germany Westphalia area as the base, there are production in the United States. Quarder is a leading technology companies, particularly in 2 - hole casting and embedded technology.

The process begins with the granular plastic material with spiral cylinder barrel via jitter feeder in the casting mould. In the cylinder by friction and heating makes raw material availability, and under huge pressure by the mold inside. According to the complexity of the process, from the amount of material to get 1-16 plastic components. On the mold and sprue turned to sorting barrels, production process starts again. Sprue is classified, the finished product will be delivered to the parts in the container.

In the process of machine modification, Quarder decided to amend some production line control system. The main purpose is to promote the operation ability of the machine, simplify the production process, and thus to minimize downtime. Originally from an old computer, A display and A keyboard, 6 "DOS application system composed of A control system, be replaced for Pro - face of graphic logic controller Logi LT - A Touch line. This graphic logic controller has 6" Touch screen, integrating operation and control functions. It has the function of the 16 points of the input and output of 16 points instead of the normal small PLC.

Jurgen Reich, electrical engineer, it is the explanation of his plan: new Pro - face terminal considerably simplifies the monitoring function of the machine. The operator can set for all the parameters corresponding orbit. At the same time, compared than before keyboard input, graphic logic controller input more clearly. 32 points is enough I/O processing each function of the machine parameters. Output control of the products sent to the right or to left, just like a lamp control. Set, can put the mould of the state is entered. The first step, the operator input the number of parts to produce and the amount of feed at a time. "This control system is unique in it can automatically control the whole process of time", Jurgen Reich explanation.

Production line starts, the entire process to the finished product out depends on the material feeding time for 3 to 5 times before, is usually between 15 to 30 seconds. Once identified, these data will be saved to the screen. The next work, Logi Touch can intelligently to identification of control, and display the error link. If in the process of casting temperature on deviation or not, the whole process will be extended, once appear this kind of circumstance, Logi Touch will identify, signal control light will brighten. At the same time, the direction can change the finished product is exported, pick out the bad parts are. The operator troubleshooting process can start.

In addition, if the feed box material quantity as described in previous case, control light will on, system will stop working transfer machine and display the product quantity, at this time, the model casting machine is still running as usual. If the instruction cannot execute completely, the operator can prepare other feed box. Through Logi Touch, the operator can confirm the whole process, transfer machine to return to work, parts production quantity will be displayed on the screen. At the same time, all parts production to monitor and counting.

Casting process, production of components of noninterference, shunt transmission and packaging process to ensure the whole production line of continuous operation.

Just Logi Touch the picture editor, Quarder engineers from Pro - face for many years experience in the field of Touch screen technology. Logic programming tool for creating a brief and simple display provides a simple platform operation. It contains more than 1800 kinds of predefined components, such as buttons, lights, bar and trend chart the basic elements of programming required. Moreover, it can create original and each element can be stored in the image library, for later use. Has the function of these words switch, switch, switch, switch button, all kinds of lights and variables, etc., can be done on the mouse to click create any operating environment. Use these data resources, the user simply drag icon to LT logic programming logic programming, it will automatically create the corresponding parts, such as a lamp or a button. Correspond to a complete IEC611313 47 ladder that mark will be very useful.

Besides having the touch of digital I/O terminal LT - H, in order to meet the needs of users, Pro - face also developed other types, such as: remote I/O, digital and analog I/O and temperature input, etc.

After four weeks of the trial, the system didn't have any problem, the operator do not have any problem in use. By touch more clear than the keyboard input data, more sensitive. Now several machine installed LT series, Jurgen Reich said: "this control system requires little maintenance. On the screen for editing, and enables us to fully enjoy the flexibility of operation. Another advantage of this solution is greatly saves space. Pro - face this kind of control terminal Logi Touch is our ideal choice. At the same time we have another project in connector test installation by Logi machine hand Touch control."
