Description

In this book for the optimisation of assembly conveyor lines we are dealing with series part production featured by a medium complexity degree and a medium number of individual components and assembly technique alternatives. Modern production techniques for medium to large series products or mass production usually involve assembly conveyor lines. The aim is to have monotonous and similar in type operations or such causing fatigue, stress and production traumas, gradually replaced by automated assembly cycles, means and techniques. Assembly alternatives involving automation, and mechanisation, programmable and adaptive control have been in addition analyzed.

Preface

In this book for the optimisation of assembly conveyor lines we are dealing with series part production featured by a medium complexity degree and a medium number of individual components and assembly technique alternatives. Modern production techniques for medium to large series products or mass production usually involve assembly conveyor lines. They still use hand labour more or less automated. The aim is to have monotonous and similar in type operations or such causing fatigue, stress and production traumas, gradually replaced by automated assembly cycles, means and techniques. This usually widely involves industrial robots and handlers. Higher productivity, lower cost and higher quality of assembled products are usually required.

Recently, latest assembly techniques for simpler or more complicated products in engineering, device manufacturing and electronics involve computer-aided automated assembly means in Flexible Automated Production Lines or other types of automated conveyor lines, which provide full automation and human labour replacement. Assembly alternatives involving automation, and mechanisation, programmable and adaptive control have been analyzed in Chapters 3-5. Practically, this means no large investment in the modernisation and expansion of the production capacity and the product’s nomenclature.
