<p>A control system is provided for a vibratory conveyor. The system comprises a detector operable to detect when the depth of product on the conveyor is at a determined minimum value. The product-conveying rate of the conveyor is adjusted so that the said depth is maintained at or around the said minimum value. This is done by logging the total time, during a given period, for which the depth of the product exceeds, or falls below, the determined minimum value, and varying the product-conveying rate depending on whether the total time is more or less than a given percentage of the period. <IMAGE></p> |
