Globally competitive – Machine manufacturer relies on Siemens motion control system for new development on presses

The key factors for every development at Sankyo are the precision, speed and efficiency of the machines.  The company relies on Siemens Motion Control solutions to develop new servo-driven belt feeders and indexers for presses.  The Siemens technology allows Sankyo to combine two demanding technical systems, a feeder and an indexer.  The future-proof automation improves productivity and allows Sankyo to maintain its position in the global market and to remain competitive.

The new servo-driven belt feeders and indexers integrated into the press allow the motor core to be arranged at an angle during stacking and the angle of rotation can be freely selected by the operator. A special vibration damping system increases operational safety. The challenge of this new solution was that the motors are cooled with compressed air instead of water in the press area. In order to ensure that the system was no more complicated than it needed to be while still adhering to international standards, Sankyo turned to Siemens for the motion control. The global company met all the Japanese manufacturer’s essential expectations. On the one hand, the highly dynamic operation using cam disks, Sankyo’s core technology, is achieved using Siemens direct drive motors. On the other, Sankyo gains through the benefits offered by Siemens’ global service network and a product range which includes all the components for the feeders (a machine for loading and unloading individual presses) and the electrical parts required for the indexers. The system also supports several operating languages.

End-to-end solution

The Siemens solution is based on a direct drive system comprising Simotics T-1FW6 high-performance torque motors for the main drive and Simotics S-1FK7 servo motors for the auxiliary drive on the intermediate release. Sinamics S120 converters complete the drive. Control is provided by a Simotion D motion control system which is operated from a Simatic Comfort Panel TP1500 HMI (Human Machine Interface) supplemented by a local Simatic ET 200SP distributed I/O. Communication is via the open industrial ethernet standard Profinet.

Huge project success and plans for the future

The Siemens solution allowed Sankyo to integrate two demanding, technical systems – a feeder and an indexer. The Siemens automation solution coordinates the individual movements of both systems and synchronizes them with the main press. The new drive system optimizes the machine characteristics of the feeder which is one of the world’s fastest servo feeders with a maximum clock speed of 1,000 strokes per minute and a feed rate of up to 100 meters per minute. Spurred on by the success of this project, Sankyo is already planning the next steps. Together with Siemens, the company intends to develop an even more powerful servo-driven feed unit for presses. The drive will still be based on Simotics motors and a Simotion motion control system. The aim is to achieve shorter cycle times for material processing.
