摘要:
The invention relates to a method and an arrangement for feeding packaging blanks (1) erected in an erecting machine from an ejection position (2) under a form chamber (3) in the machine, where an erecting plunger (4) inside the erected blank relinquishes it for transfer to an underlying delivery conveyor (5) for further horizontal conveyance to a filling and sealing station. Substantially simultaneously as it is relinquished, the erected blank (1) is captured by a vacuum conveyor (8), known per se, which includes at least one vertically moving belt (9). One side wall (6), and possibly a lid (7) attached in an upstanding attitude to the wall of the erected blank are urged against the belt for controlled movement downwards until the bottom (11) of the erected blank comes into contact with the upper surface (12) of the delivery conveyor (5) substantially simultaneously as the erected blank is automatically released from the vacuum conveyor (8) for further horizontal conveyance by the delivery conveyor to a filling and sealing station.

The present invention relates to a method and a machine for forming a box (C) from a blank (1), in which the blank is removed from a storage magazine (30) by suction, the blank is fed horizontally above a support (43) having an upper edge with a V-shaped cross section and faces that correspond to the main walls and are inclined with respect to the horizontal by a given angle α, such that the central folding line, known as the reference folding line, is next to the edge, the blank (1) is placed on the support (43), the blank is then pressed against a polygonal mandrel (47), the upper edge of which coincides with and/or is in line with the upper edge of the support, said mandrel having a shape complementary to that of the box, so as to form a tubular box body at an angle to the horizontal, the bottom of the box is formed by folding and pressing together flaps after application of glue, and the inclined box thus formed is ejected, is positioned upright and then is transferred to a filling station.

The invention relates to such a manufacturing machine in which the pressing means (20) for rolling the strips of material (2) against the forming mandrel (3) and the traction means (10) for moving said shaped strips of material along said forming mandrel (3) are separate in order to separate these two functions. The pressing means (20) comprise a plurality of press rollers (21), mounted with the freedom to rotate about their axis, deformable and distributed radially around said forming mandrel (3) so as to hug the periphery of said mandrel. The traction means (10) are multiple: traction belts (11) borne by drive rollers (12) positioned downstream of said pressing means (20).

The object of the invention is a method for a packaging machine, in the container-forming unit of which the casing is formed to be substantially ready, whereby the sidewall blank (O) of the casing is placed on at least one mandrel or the like, preferably on the outer surface (2a) of a wrapping mandrel in the container-forming unit. The first end member (P) of the casing is placed on the end face of the mandrel, and the end member is joined to the bottom portion of the sidewall blank. The casing formed on the mandrel is removed from the mandrel to be advanced to the next process stage to be carried out in the packaging machine. In order to remove the casing (OP) from the mandrel (2), axial transfer energy is directed towards the inner surface of the end member (P) of the casing (OP). To facilitate the removal, the contact between the iner surface of the sidewall blank (O) and the outer surface (2a) of the mandrel (2) is released in radial direction. It is possible to utilise a gaseous pressure medium brought from the inside of the mandrel (2) to generate the axial transfer energy and to release the contact in radial direction.

There is described a method for producing a container (1) comprising a sleeve-like main portion (5) and an end piece (12) attached to the main portion (5); the method comprises the steps of: - advancing, along a given path (P), at least one forming member (38) having an axis (E) transversal to the path (P), and delimited by a top surface (33) and by a lateral surface (34) extending around said axis (E); - feeding the end piece (12) on the top surface (33) of the forming member (38); - wrapping a sheet (2) of packaging material around the lateral surface (34) of the forming member (38) such that the opposite side edges (4a, 4b) of the sheet (2) parallel to the axis (E) overlap one another; - joining the overlapped edges (4a, 4b) of the sheet (2) by a longitudinal seal (7) so as to form the sleeve-like main portion (5) of the container (1); and - joining a peripheral edge (13) of the end piece (12) to an upper end (6) of the sleeve-like main portion (5) by a transversal seal (52) extending around the axis (E).

The present invention relates to a box, to a blank or blank assembly, and to a method and device for forming a box made of a corrugated cardboard sheet material having a polygonal cross-section. Said box includes a strap comprising at least four main rectangular panels, provided with at least one series of flaps suitable for at least partially forming the bottom and/or the top of the box, at least two of said main side panels being connected to a main central panel via intermediate panels forming cut corners without flaps. At least two of the cut corners are formed by at least two rectangular cut side portions which are connected together or to the adjacent main panel by a folding line, said cut side portions having a width of between 3 mm and 20 mm.
