Operating device for placing or retrieving bottle-like piece goods

A method of moving cylindrical piece goods, the method comprising:

• moving a gripping jaw assembly comprising first and second gripping jaws disposed opposed to each other along a lengthwise axis, the first and second gripping jaws having inner surfaces, wherein a distance between upper portions of the inner surfaces is greater than a distance between lower portions of the opposed inner surfaces in a first position of the first and second gripping jaws, wherein the moving comprises moving, by a first actuation unit, the gripping jaw assembly along the lengthwise axis toward a storage place having one or more piece goods;
• lifting, by the first and second gripping jaws, a first cylindrical piece good from below;
• catching, by a catching section at an end of the first gripping jaw, the first cylindrical piece good between the first and second gripping jaws;
• moving, by the first actuation unit, the first and second gripping jaws to move the first cylindrical piece good to a different location;
• and
• pulling the first cylindrical piece good onto a tray disposed below the first and second gripping jaws.

• moving, by the first actuation unit, the first and second gripping jaws adjacent a first piece good disposed in a first location of the storage place;
• engaging, by the first and second gripping jaws, the first piece good;
• catching, by a catching section at an end of the first gripping jaw, the first piece good between the first and second gripping jaws;
• moving, by the first actuation unit, the first and second gripping jaws away from the first location of the storage place to remove the first piece good from the first location of the storage place;
• and
• pulling the first piece good from the storage place onto a tray disposed below the first and second gripping jaws.
