ABSTRACT:
A positioning mechanism for a traveling automatic maintenance unit for a textile ring spinning machine or the like, which unit includes a carriage movable on spaced tracks along the spinning stations of the machine for automatically stopping at spinning stations that are determined to require maintenance. The mechanism includes a frame that is transversely pivotally mounted on the carriage on a longitudinally extending shaft. The frame carries an automatically operable maintenance mechanism that pivots with the frame transversely into operating position at a spinning station. Transverse movement of the frame is accomplished by a pneumatic piston-cylinder mechanism that manipulates a sliding element on a transversely extending rod of a slide guide with the frame connected to the sliding element by a connecting linkage. An aligning device in the form of a bifurcated member is also movable with the sliding element to move into straddling engagement with the vertically depending spindle bearing of the spinning station to guide the carriage, frame and maintenance unit into proper alignment. The bifurcated member has an aligning slot with an opening wider than the engaging extent of the spindle bearing for initial engagement therewith and tapering to an aligning width at which the slot extends with generally parallel inner walls to maintain the maintenance unit in proper alignment during movement into operating position. The aligning slot has an inner end that serves as a stop for maintaining the maintenance unit in operating position, and a latched element releasably engages the spindle bearing and maintains the inner end of the aligning slot against the spindle bearing to maintain the maintenance unit in proper operating position.
