Abstract
Method for automatically replacing the spout nozzle of a slide closure with a robot for manipulating the slide closure with an appropriate apparatus, the spout nozzle being able to be clamped against the slide plate of the slide closure by a carrying ring that can be released by turning. During the changing procedure, the carrying ring is turned with a defined torque, by means of which the new spout nozzle is clamped with a likewise defined tension force against the slide plate. In this way, operational reliability of the slide closure is guaranteed, independently of any tolerance and other deviations. The apparatus for implementing the method includes a gripping lance with clamping jaws for manipulating the spout nozzle and a gripping ring with catches for manipulating the carrying ring. The gripping ring can be actuated by a hydraulic rotation cylinder. A pneumatic cylinder is used to actuate the gripping lance.
