摘要:
The invention relates to a method for automatic replacement of the discharge shell on a sliding closure (3) by means of a robot (2) for manipulating the sliding closure with a suitable device, wherein the discharge shell can be clamped against the slide plate of the sliding closure by means of a carrier ring that can be detached by rotation. According to the invention, the carrier ring is rotated with a defined torque during the replacement process, whereby the new discharge shell is clamped against the slide plate with a likewise defined clamping force. Thereby the operational reliability of the sliding closure is guaranteed, regardless of any tolerances or other deviations. The device for performing the method includes a gripping lance (26) having clamping jaws (29) for manipulating the discharge shell, and a gripping ring (12) having snap elements (20) for manipulating the carrier ring. The gripping ring (12) can be operated by a hydraulic rotation cylinder (14). A pneumatic cylinder (31) is used for operating the gripping lance (26).
