✦ Synopsis
In many areas of the food manufacturing industry use of contacting mechanical devices to manipulate the products frequently causes damage to the products and/or gives rise to system jamming particularly at higher feed flow rates. Techniques for manipulating objects by non-contacting means, namely by power air-jets, have been under development at Birmingham University. The advantage of non-contacting technology is the increase of flow rates of manufactured products beyond that currently sustainable by mechanical means without causing damage and system hold-ups. In the present paper, a technique for motion control of objects is presented which utilizes pulse width modulated fast acting power air-jets with piezotranslator drive stages, a transputer based digital image processor for position feedback and fuzzy logic techniques for the control algorithm.
