Optimising compressed air at assembly units

In the context of the technician´s training at the vocational school in Kirchhain a project is done for the company Druck- und Spritzgußwerk Hettich GmbH und Co. KG. The project work comprises 220 hours over a period of 8 months. All costs are covered by Hettich. With approximately 530 workers the company produces for example dampers for drawers for the furniture industry or systems for window regulators and locking systems for glove box departments for the automobile industry. Aim of the project is the economization and optimization of compressed air supplies at the assembly lines in the Center “Dämpfungssysteme”. For the production of damper-systems machines are used, which are mostly controlled by compressed air. Useful solutions are developed to reduce the consumption of compressed air and to save costs at Hettich because compressed air is one of the most expensive energy sources. Therefore, topic of this project is: Economization and optimization of compressed air at assembly lines.

Because of this topic there are the following central questions:

• How can costs and energy be saved?
• How can compressed air be saved?
• How can maintenance be improved?

Because of this the project gives an overview about the consumption of compressed air the assembly lines in the Center Dämpfungssysteme. The power station provides the Center Dämpfungssysteme with about 80 to 100 liter per minute. The company EGF keeps records of the consumption of compressed air at Hettich hourly.

The project covers the following topics: the economy of the installed parts, the feasibility of an elaborated comparison and the aim to save costs and energy.
The economization and optimization of compressed air at assembly lines should be reached while comparing different elements and drive variants. Furthermore the durability and the initial recognition costs of the different components are considered. The optimum-principe should be used ( minimal costs – maximal use ).

In cooperation with the companies Festo and Bosch Rexroth reasonable and assimilable building elements have to be found, which are applicable for economization and optimization. Because of a maximum project duration of 8 months, it is not possible to implement the work practically. The different solution proposals can only be elaborated theoretically, because Hettich produces 7 days a week in shift-work.
