The intelligent and network-ready ultrasonic generator: Ready for Industrie 4.0
With the new automation ultrasonic generator AMG, machine builder Herrmann Ultraschall takes the next step in digital manufacturing and towards the smart factory of the future. Product launch at the K 2016
The new ULTRAPLAST AMG ultrasonic generator from Herrmann Ultraschall is a product line specially developed for automation environments. It is particularly aimed at customized machine builders, who specialize in building large multi-head ultrasonic welding systems. These are mostly suppliers for the automotive industry, but industries such as medical, electronics and packaging technology will also benefit from this new development. The AMG meets important conditions for Industrie 4.0: suitable interfaces for secure communication, network-ready with intelligent sensor signals and device replaceability without data loss.
Integrated into complex control processes, the AMG is no longer a simple ultrasonic source, but instead a central, intelligent network participant within the ultrasonic welding machine. By means of control algorithms, the generator adjusts its welding parameters to the changes in the environmental conditions, allowing it to influence the weld process in a self-optimizing manner and achieve consistent product quality. Critical process states can be recognized and dealt with individually. The information is reported to the machine controllers and used for sorting out defective parts. This increasestheproductionsafety.
The ULTRAPLAST AMG offers a product platform with modular hardware versions in the ultrasonic frequencies 35, 30 and 20 kHz with a power range of 700 to 2000 Watt. It fits in all standard electrical cabinets with a depth of 300 mm. Via the new programming modules, the customer can quickly and independently use the full functional scope of the ultrasonic generator – in other words optimally control and monitor the weld process. This reduces engineering and start-up times.
For simple communication between generator and machine controller, an Ethernet communication interface (HCI Herrmann Communication Interface) is implemented in the device. This allows a fast and interference-free data and signal exchange with a manufacturer-independent PLC, i.e. a problem-fee exchange of the most important weld process data and status information. Thus advanced settings and control commandos can also be processed. If further process data and measured values are required, the ULTRAPLAST AMG can optionally be equipped with a real-time fieldbus interface. Seven of the most common fieldbus formats are supported, from Profibus and Profinet up to DeviceNet and EtherNet/IP.
Diagnostics and process optimization
As a further tool, the diagnostics and operating software AMGsim is available, with which all process data can be accessed via the Ethernet network during production. The process optimization is supported by a graphical display of the most important welding parameters and makes the weld process easy to understand.
