<p>2.1. In installation systems with automatic screw connection, satisfactory screw hardware is needed. In the past, defective screws have usually been eliminated manually or by costly optical sorting devices. The new sorting device is intended to single out defective fixing components reliably and economically.
<??>2.2. Defective components are sorted out from the dimensionally accurate fixing components by a consecutive arrangement of mechanical measuring stations (10, 13) and electrical measuring stations (21, 22, 25) which operate by the eddy current principle, and by ejector devices (10, 12, 3). The mechanical pre-sorting largely prevents dimensional errors from being compensated at the electrical measuring stations. As a result, very high reliability of the overall installation is achieved.
<??>2.3. The sorting device is suitable for automatic installation systems for feeding screws to screw pumps. It can also be used, for example, by screw manufacturers for the provision of satisfactory screw hardware.
