Harmonized interfaces and intelligent line management enable up to 10% higher efficiency in packaging machines
Global branded goods manufacturers expect concepts from their machine suppliers to increase their process efficiency. The specialist for end-of-line packaging ETT Verpackungstechnik has integrated standardized solutions and systems into its machines for these requirements.
ETT has been a first supplier to well-known manufacturers in the consumer goods and pharmaceutical sectors for more than three decades. The medium-sized company and Siemens have been working together as partners since the 1990s. This is highly appreciated by both sides and has already resulted in several joint innovations.
As an innovative end-of-line packer, ETT sees it as its duty to continuously improve its own products, processes and structures. Thus, the decision to switch to the OMAC PackML standard, which is widely used and accepted by the market, was also a decision with perspective! And a development that has paid off: Time savings in project planning, flexibility through modularization, as well as technical readiness for the future. “We, ETT, offer flexible, customer-oriented solutions with a high level of standardization at the same time,” Oliver Bergmann, Head of Electrical Engineering at ETT.
ETT, as a secondary packer, also attaches great importance to the integration into plant systems horizontally, but especially vertically. Here, ETT is not only continuously expanding its know-how with the OMAC PackML and OPC UA standards – they are also deepening their offering for the vertical integration of their machines. The goal: All plant components receive an identical structure in language and code in order to further optimize integration, diagnostics and availability – allowing the plant to be operated around the clock with maximum productivity. For example, a well-known detergent manufacturer succeeded in increasing efficiency in its production plants by 10% with harmonized interfaces and intelligent line management from Siemens.
With the Brownfield Connection Concept from Siemens, older existing machines can be upgraded, even without changing the existing machine control, and thus productivity increases can also be realized for these machines. ETT offers this concept for upgrading older machines. Process-relevant variables such as operating states, machine speed, piece counts and other signals are made available for further visualization and analysis. This allows OEE evaluations both – near the machine and also across locations with the IoT-as-a-Service solution MindSphere. In addition to maximum production efficiency, energy efficiency is also addressed right from the design stage of the machines. For example, the consistent DC link circuits in the SINAMICS S120 drive systems enable energy savings and visibly reduce operating costs. With this drive system, even old production lines can be upgraded in an energy-efficient way.
