ABSTRACT:
Each of the operating stations is provided with a locating element while the service tender carries a sensor for aligning the service tender with a selected operating stations. The sensor includes a rotatable member on which a pair of rollers is mounted and from which a leaf extends to cooperate with various photodetectors. With the sensor in an operative position, the rollers sequentially contact the locating element of a selected operating station and by pivoting cause the leaf to cooperate with the photodetectors to generate a sequence of signals. This sequence of signals is used to slow the service tender and to thereafter brake the service tender to a halt in alignment with the selected operating station.
Should the service tender overrun the locating element, signals are also generated to reverse the direction of movement of the service tender in order to effect alignment.
