<p>Process and unit, whereby component parts may be withdrawn from a magazine, transported up to the area of the work-piece and laid on the latter, respectively inserted therein at a predetermined location and with accuracy. The component part held by a transport member will normally take an excentric respectively twisted position with respect to a theoretical axis. In order to determine the instantaneous effective position of the component part, the latter is brought during its transport from the magazine to the work-piece in a position sensing unit which determines the effective position of the component part, for example by scanning the component part by means of a laser beam according to the reflexion or shadow principle, and which produces one or a plurality of correction signals. These signals are evaluated for effecting a correction to the displacement path of the transport member and/or to the position of the work-piece.</p> |
