Contact free conveying apparatus for transporting items

摘要

The bed of the conveyer consists of a porous board with air or a suitable gas flowing through the pores (3). The air forms a cushion which supports the component (1) to be transported. Transverse strip electrodes (2) are positioned at intervals along the length of the board. The spacing of the electrodes is suitable for the size of the components being transported. A high voltage, e.g. 3 kv is applied to pairs of electrodes to form a traveling wave which draws a component along the conveyer.
