Fastening Technology 2002

A system of versatility – intelligent basic functions as a key for success of the Building Kit

Where the task is to create special purpose machinery and workplaces, System Building Kits represent the state-of-the-art, all-round solution. Sophisticated modular designs of standard elements combine with a wide range of accessories to produce exactly the right tailor-made solution for a particular application. It is the fastener technology that provides the user with this tremendous versatility in implementing his design.

The objective of a Building Kit System is to make it possible to create as many applications as possible using standard components. These components must be applicable to a wide range of functions and, at the same time, be so versatile that they can be combined with other components to enable special solutions to be implemented. This apparent paradox is often difficult to put into practice. In order to be both functional and economical, such Building Kits have to provide not only a range of universally applicable components but also some special-purpose units with dedicated functions.

One crucial feature of a Building Kit System are the basic elements. These form the basis of every construction and determine the versatility of the possible applications. In this respect, the fastening elements are of key importance. They decide how quickly and how securely the application is constructed and how sturdy the overall construction is. One of the first companies to notice this was item Industrietechnik und Maschinenbau GmbH in Solingen, Germany, and it became a fundamental basis of the MB System. As a result, item's MB Building Kit System is based around fastener technology whose physical properties and broad spectrum of applications leave nothing to be desired.

The basic elements: fundamental to machines

As a rule, the tasks expected of a machine construction are defined in advance and recorded in the specifications. Although the individual machine elements may be able to perform numerous functions, the designer must be able to compile the functions required to meet the specifications for that application – irrespective of how complex the machine is and in the shortest possible time. The machine's basic framework has to be able to absorb the loads generated and incorporate the required machine functions. At the same time, it is important to reduce the required planning time by the designer to a minimum and present him with all the options for possible design modifications at a later date. The result: the basic framework has to be designed to be adaptable for preferences and adaptations that may only become apparent later. The basic requirements expected of such a framework are rigidity, versatility, rapid (and as a result, time and cost saving) construction and, finally, the overall visual appearance of the machine were the starting points of the development of a modular building kit. The item MB Building Kit System was developed according to these guidelines.

Frameworks made of aluminium system profiles are most suited to meet the requirements of such a framework. This principal of "open architecture" is, on the one hand, in keeping with the essential principal of attachability of as many different functional units (e.g. linear guides, drives, pneumatic devices etc.) as possible and on the other hand guarantees tremendous versatility in integrating the machine in the work flow of a process, for instance in the material handling. Additionally the framework, made up of basic elements, needs an easy way to be adapted to suit the foundations or other components of existing production machinery. Where the rapid erection of sturdy and load-resistant constructions using profiles is required, the fastener technology plays a crucial role.Where the rapid erection of sturdy and load-resistant constructions using profiles is required, the fastener technology plays a crucial role. Its functionality, i.e. reliable physical operation of the components, coupled with simple assembly and minimum machining, will determine in the end how successful the entire construction is, that is, how efficiently and economically the machine or workplace functions. A "successful" construction is one in which the user learns quickly and easily to make use of the functions he needs but where he is unaware of the complexity and sophistication of the technology. The main thing is that the construction holds firm. Aluminium Building Kits, although already proved, still have to fight against an old prejudice: the screwed fastening of two profiles might not have the same stability and durability like weld joints. It is true that there exist systems of fastening for aluminium profiles which are only determined by the postulation of time-saving assembly but not by a safe active principle for strong fastening.
