Int J Adv Manuf Technol (2005) 25: 551–559 DOI 10.1007/s00170-003-1843-3 ORIGINAL ARTICLE S.H. Masood · B. Abbas · E. Shayan · A. Kara An investigation into design and manufacturing of mechanical conveyors systems for food processing Received: 29 March 2003 / Accepted: 21 June 2003 / Published online: 23 June 2004  Springer-Verlag London Limited 2004 Abstract This paper presents the results of a research investi- gation undertaken to develop methodologies and techniques that will reduce the cost and time of the design, manufacturing and assembly of mechanical conveyor systems used in the food and beverage industry. The improved methodology for design and production of conveyor components is based on the minimisa- tion of materials, parts and costs, using the rules of design for manufacture and design for assembly. Results obtained on a test conveyor system verify the benefits of using the improved tech- niques. The overall material cost was reduced by 19% and the overall assembly cost was reduced by 20% compared to conven- tional methods.

Most of the processing and packaging of food and drink in- volve continuous operations where cartons, bottles or cans are re- quired to move at a controlled speed for filling or assembly oper- ations. Their operations require highly efficient and reliable me- chanical conveyors, which range from overhead types to floor- mounted types of chain, roller or belt driven conveyor systems. In recent years, immense pressure from clients for low cost but efficient mechanical conveyor systems has pushed con- veyor manufacturers to review their current design and assembly methods and look at an alternative means to manufacture more economical and reliable conveyors for their clients. At present, S.H. Masood (u) · B. Abbas · E. Shayan · A. Kara Industrial Research Institute Swinburne, Swinburne University of Technology, Hawthorn, Melbourne 3122, Australia E-mail: smasood@swin.edu.au most material handling devices, both hardware and software, are highly specialised, inflexible and costly to configure, install and maintain [1]. Conveyors are fixed in terms of their locations and the conveyor belts according to their synchronised speeds, mak- ing any changeover of the conveyor system very difficult and ex- pensive. In today’s radically changing industrial markets, there is a need to implement a new manufacturing strategy, a new system operational concept and a new system control software and hard- ware development concept, that can be applied to the design of a new generation of open, flexible material handling systems [2]. Ho and Ranky [3] proposed a new modular and reconfigurable 2D and 3D conve
