Definitions

  • the invention relates to a packaging made of thin cardboard with a projection formed in a wall of the same from the cardboard by deformation, in particular folding boxes (hinge-lid pack) for cigarettes with projections on the inside of side walls for supporting a collar, the projection being supported by at least a punch cut in the carton, in particular directed transversely to the longitudinal direction of the wall, is limited and consists of a deformation of the carton limited by the punch cut or a cutting edge thereof.
  • the invention further relates to a method and an apparatus for producing projections in the walls of packaging.
  • Hinged boxes of cigarettes or the like may be mentioned as an example.
  • This type of pack is with a collar equipped, which dips with a section into a box part of the hinged box.
  • inward-facing stops are attached to the side walls thereof, on which lower edges of the collar are placed.
  • a packaging with stops for this purpose is the subject of (post-published) DE-A-41 22 900. The production of this stop in the ongoing manufacturing process is difficult.
  • US 4 216 898 also shows inwardly directed stops (corresponds to the preamble as claim 1). More precisely, they are inwardly curved, partially cut out and L-shaped wall sections.
  • US Pat. No. 4,629,447 shows a device and a method for punching and deforming tabs in cartons. A knife acting perpendicular to the carton plane is simultaneously moved in the opposite direction to the folding members that bend open the tabs. Due to the various organs and the required sequence of steps, the method and the device are very complex.
  • US 4,725,261 deals with an apparatus and a method for punching out a tab from a blank for a packaging. A punch is made with the tool used and at the same time a part of the punched section is bent downwards. The preamble of claims 4 and 5 corresponds to this prior art.
  • the invention has for its object to achieve by constructive design of projections or stops formed by deformation and procedural and device engineering measures that these projections or stops can be attached in the ongoing manufacturing process for packaging, especially hinged boxes.
  • the packaging according to the invention is characterized in that the deformation is designed as a curvature with a straight-line punch cut to limit the same, and that the curvature merges into the wall on all sides outside the area of the punch cut.
  • the method according to the invention for producing protrusions in the walls of cardboard packaging, in particular folding boxes for cigarettes, a protrusion being produced by simultaneously punching and deforming the cardboard is characterized in that the protrusion is formed by a cylindrical workpiece with a circular cutting edge and a subsequent cylindrical one Shell surface is formed so that a stamped cut and a limited by this, acting as a protrusion are produced.
  • the device according to the invention for producing projections in the walls of packaging made of cardboard, in particular hinged boxes for cigarettes, with a tool which can be pressed against the cardboard or against the wall of the packaging and has a stamping piece by means of which a stamped cut can be produced is characterized in that Punching piece is a cylindrical workpiece with a circular end face and a circular punching edge, a part of a cylindrical outer surface of the punching piece adjoining the latter being used to form a curvature in the box delimited by the punching cut.
  • Tool and a corresponding counter tool are preferably arranged on the circumference of rotating organs, in particular rollers, between which blanks for the packaging or a web of packaging material are passed. At least once with each revolution of the two opposing rollers, the tool and counter tool come into engagement in such a way that a projection is created in the blank.
  • the invention is particularly suitable for the attachment of projections for supporting collars in hinged boxes.
  • the projection is attached in the region of side walls or inner side flaps thereof during the ongoing transport of the blank for the hinged box or a material web made of packaging material.
  • the projections or stops can also be of interest in another context.
  • FIG. 1 a folding box shown in FIG. 1 consists of a lower box part 11 and a cover 12 connected to it in the region of a rear wall.
  • a collar 13 formed from a separate blank.
  • This consists of a collar front wall 14 and collar side walls 15, 16. The latter lie on the inside of box side walls 17, 18, to be precise on inner side tabs 19, 20 of these box side walls.
  • inwardly projecting projections 10 or stops are provided on the inside of the box side walls 17, 18, namely on the inner side tabs 19, 20 thereof. On this the collar 13 is supported with the lower edges of the collar side walls 15, 16.
  • the projections 10 are formed by deforming the material of a wall of the hinged box, namely the side tabs 19, 20.
  • a transverse or horizontal punch cut 21 is made.
  • a region adjoining this - in the present exemplary embodiment below the punch cut 21 - is deformed inward to form the projection 10.
  • the deformation is designed here in such a way that an arch-shaped, in particular circular arch-shaped curvature 22 arises from the packaging material. Outside the area of the punch cut 21, this gradually runs out into the wall, that is to say into the side tabs 19, 20.
  • An edge 23 of the punch cut 21 forms the support or support surface for the part to be supported (collar 13).
  • the projection 10 formed in this way is produced completely in one operation.
  • a special punching and embossing tool is used for this purpose, which at the same time makes the punch cut 21 and causes the deformation of the material, that is to say the side tabs 19, 20 here.
  • the punching and embossing tool consists of a cylindrical punching piece 24. This has the shape of a bolt.
  • a transverse end face 25 creates a circular edge, which at the same time forms a cutting edge 26.
  • a section thereof is pressed against the blank, namely here against the side tabs 19, 20.
  • the straight cutting punch 21 is carried out by the punch cutting edge 26.
  • One adjacent to the cutting edge 26 The cylindrical region of the punch 24 causes the deformation to form the curvature 22.
  • the manufacture or attachment of the projections 10 is integrated into the continuous manufacturing process of the packaging.
  • the projections 10 are attached during the continuous conveyance of the blanks or the material web.
  • the punching tool namely the punching piece 24
  • the punching piece 24 is also arranged on a rotating element, namely on a punching roll 30.
  • This is provided with a cutout 31 and a recess 32 in the area where the punching piece 24 is attached.
  • a projection 33 protruding in the radial direction remains between these. This has the outside of the circumferential surface of the punching roller 30.
  • the bolt-like punching piece 24 is fastened in the region of the projection 33 parallel to a tangential (imaginary) plane, that is to say transversely to the axis of the punching roller 30.
  • the projection 33 is provided with a transverse axial bore 34. In this, the punch 24 is seated against a collar 35.
  • a fastening bolt 36 holds the punch 24 in this position.
  • the projection 33 is designed so that a radially outer area at the free end of the punch 24 on the radially outer side of the punch roller 30 is exposed.
  • a radially outer area of the cutting edge 26 lies in the movement path of the counter-roller 28, which is also driven in rotation.
  • the distance between the counter-roller 28 and the punching roller 30 is such that an outer edge region of the cutting edge 26 into the recess 29 of the counter-roller 28, which is moved exactly synchronously with the punching roller 30 entry.
  • the counter roller 28 is also provided with a recess 37.
  • Counter roll 28 and punch roll 30 are formed from two roll halves in the present case.
  • the parts or halves of the rollers serving as tools can thus be easily replaced.
  • counter roller 28 and punch roller 30 are complex organs.
  • Counter roll 28 and punch roll 30 are designed as disks which are essentially only effective in the area of the projections 10 to be attached.
  • the disks are seated on rotatably driven shafts 45, 46. Additional tool disks are mounted on these, which assume shaping functions for the cutting.
  • a coding roller 47 is located on the upper shaft 45 in the middle between the counter-rollers 28 and punching rollers 30 mounted on the side. This has the task of embossing (numerical) embossing on the blank.
  • transport disks 48, 49 on the shafts 45 and 46. These serve for the exact conveying of the blank. The distance between the lateral surfaces of these transport disks 48, 49 is therefore precisely matched to the thickness of the blank.
  • side flanges 50, 51 are arranged on the shafts 45, 46, which act as a support.
  • FIG. 2 shows schematically the one of interest Part of such a packaging machine.
  • the blanks are removed from a blank magazine 38 individually by means of a removal device (so-called dispenser).
  • the blanks are then conveyed along an obliquely downwardly inclined transport path 40 into an insertion station above a plate-shaped folding turret 42 which runs in the horizontal plane.
  • the blanks are introduced into pockets of the folding turret 42 by means of a plunger 43 which can be moved downward.
  • the unit for attaching the projection 10 is integrated in the transport track 40.
  • Counter roller 28 and punch roller 30 are upstream of a glue unit 44 in the conveying direction.
  • the glue unit 44 applies glue spots to the side tabs 19, 20 of the blank.
