Feed4ward Control used their in-depth Siemens PLC knowledge and considerable automation design experience to bring significant improvements to production lines at specialist manufacturing company SI Protech (UK) Ltd in Littlehampton, UK.
The upgrade and enhancements to the valve assembly and test process has reduced the time needed to test the valves for leaks and enables accurately test results to be accurately recorded. Further improvements allow valves to be fed from either an automated machine or from an existing conveyor that is manually loaded by an operator, giving extra flexibility and less production downtime.
In response to SI Protech’s initial brief, Feed4ward’s Adriane Bestic analysed the existing Siemens control environment and designed a number of significant changes to improve the system:
- PLC software was implemented to allow a robot arm to place parts from two separate infeed conveyors onto a rotary table. This provides manufacturing flexibility as the assembly machine can now be either loaded manually or automatically without the need for reconfiguration.
- Further software modifications provide improvements to six valve leak testers. providing both individual and automated control. This was achieved by by integrating various control and status signals that were not previously available to the PLC.
- Additional screens were added to the Siemens KTP700 HMI to enable operators to manually control the leak testers and also to allow changeover between two different infeed conveyors without the need for manual intervention
- A Profinet-connected Siemens ET200SP distributed IO station was used to increase the number of digital inputs and outputs available for monitoring and control without the need to upgrade the existing PLC
All changes requested by SI Protech were documented, implemented, commissioned and tested by Feed4ward and followed our robust quality assurance and review processes.
Rhys Lewis, CEO at Feed4ward said “We were pleased to work with SI Protech on this interesting and challenging project. Our deep knowledge of Siemens control and automation products coupled with our collaborative approach meant that we were able to work together with SI Protech to achieve the improvements they needed.”
