Abstract

Process and apparatus for introducing compressible packs, especially bundles (10) or bundle groups (16, 17) comprised of small packs (11) of paper tissues into a carton (15). Articles or packs or pack groups of cellulose products are difficult to handle from the point of view of packaging technology. For the introduction into a carton (15) open at the top, bundle groups (16, 17) consisting of a multitude of small packs (11) of paper tissues are mechanically compressed, especially into a V-shaped form, then grasped on the top side by a lifting head (23) with suction holders (24 to 27) and held by suction. The lifting head (23) conveys a complete layer of bundle groups (16, 17) into the carton (15) from above, the compressed, reduced formation of the bundles (10) being maintained until they are deposited in the carton (15).

Claims12

Dependent claims

Process for introducing packs made of compressible, air-permeable material into large containers characterized by the following features:

a) providing each pack with contents and a wrapper which completely covers the contents of the pack,
b) providing each wrapper with an air-permeable closure seam located in a region of a top side of the respective pack,
c) grasping each pack by a lifting member with a suction head having suction holders which operate by applying vacuum pressure to each pack,
d) wherein the suction head grasps each pack on its top side, at least in the region of the closure seam,
e) reducing the volume of each pack by suction applied by the lifting member,
f) transporting each pack to a large container, in the volume-reduced form, while each pack is grasped by the vacuum force of the lifting member applied to each top side, and stacking each pack in the large container,
g) after each pack has been stacked in the large container, releasing the suction head from each pack by ventilation,
h) wherein, after the suction head has been released from each pack and thus also after the vacuum force has been removed, each pack substantially regains its original volume by the uptake of air.
