Device for shaping a flat blank into a container

摘要

In a device for shaping a flat blank (46) made of cardboard into a container (48), comprising a shaping tool (50) and a ram (10) which can be moved in a primary shaping direction (z) into the shaping tool (50) so as to erect the flat blank by means of the shaping tool (50), at least two lateral walls (18) which can be pivoted about a respective pivot axis (s) located transversely relative to the primary shaping direction (z) are hinged to the ram (10), whereby a main surface defined by the free end edges (19) of the lateral walls (18) can be adjusted. In order to carry out a pivoting motion, the lateral walls (18) are seated in a non-positively sliding manner against wedge elements (28) by means of pretensioned spring elements (22, 24), the wedge elements being displaceable in the primary shaping direction (z).

1. A device for shaping a cardboard flat blank (46) into a container (48), comprising a shaping tool (50) and a ram (10) which is movable in a principal shaping direction (z) into the shaping tool (50) so as to erect the flat blank (46) via the shaping tool (50), wherein a base area of the ram (10) is adjustable in at least one shape-shaping direction (x, y) lying transversely to the principal shaping direction (z), characterized in that at least two side walls (18) pivotable about, respectively, a pivot axis (s) lying transversely to the principal shaping direction (z) are articulately attached to the ram (10), whereby a base area delimited by free end edges (19) of the side walls (18) is adjustable, the side walls (18) bearing in a frictionally sliding manner by means of pretensioned spring elements (22, 24), for the execution of a pivot motion, against wedge elements (28) which are displaceable in the principal shaping direction (z), wherein the ram (10) has a lower base plate (14) and the wedge elements (28) are disposed between the lower base plate (14) and the side walls (18), wherein the wedge elements (28) bear against the side walls (18).
