Real-time collection of control data for various types of press-in devices through the MES interface.
Solution 1 Increase productivity by multi-variable response of programmable controller and RFID
The programmable controller can change the pressing force of the servo press according to the vehicle information read in the RFID, and only one pressing device can cope with the pressing of a variety of parts, thereby increasing productivity.
It is changed to a servo press that can be easily controlled from the hydraulic press of the press-in device, and after changing the press-in thrust based on the model information read in the RFID, only one press-in device can be used to press in multiple models .
If both RFID and servo presses are Mitsubishi Electric programmable controllers in partner products, a high-affinity system can be constructed.
Solution 2 Use the example ladder diagram to shorten the development man-hours of the communication program for the servo press
For the development of ladder diagram programs related to servo presses and RFID communications, sample ladder diagrams and FB program libraries that can be downloaded for free from the Web can be used to shorten the man-hours for system development.
In the MELSOFT Library on the Mitsubishi Electric FA website, an example ladder diagram of a system that communicates with a servo press made by Daiichi Dentsu, as well as an example ladder diagram and FB library of a system connected to RFID made by BALLUFF, are available for free. download.
By using this example ladder diagram, the development man-hours for the program connecting the programmable controller and each device can be greatly reduced.
Solution 3 Use MES interface to collect data in real time
After using the MES interface, the measurement information of the press-in device can be sent to the production management system in real time without the need for a gateway computer.
If the MES interface is used, the measurement information can be directly sent to the production management system in real time without the need for a gateway computer to realize the visualization of the press-in device.
Automatically generate SQL with simple settings without programs, and simply connect production equipment and MES database.
Use the event sending function of equipment information to reduce the load of the information system.
Can accept production instructions, send and receive data with time information.
Use the data buffer function when communication is abnormal to ensure data reliability.
