Abstract
The lifting and transportation of sensitive articles incapable of bearing a mechanical load, without manual involvement, presents special difficulties in packaging technology. This applies, above all, to tray packs in which articles are arranged standing on a bottom part (11) of small height, without any additional anchoring. For grasping and lifting articles of this type, there is provided a raisable and lowerable suction box (15) which, with suitable dimensions, is placed over the article in the manner of a bell. By the generation of a vacuum within the suction box (15), the article (tray pack 10) is held carefully and can be lifted by means of the suction box (15). Side walls (22) of the suction box (15) are arranged pivotably, to make it easier to place the suction box (15) onto the article.
