Definitions

  • the present invention relates to the field of manufacturing packaging, in particular packaging which is at least partially made from a material that is essentially non-thermoplastically deformable.
  • a device for deep-drawing a cardboard blank into a bowl-shaped or cup-shaped object is known.
  • Individual blanks are completely punched out of a cardboard web by means of a punching device.
  • the punched-out individual blanks are then fed to a forming station for forming.
  • the molding station comprises a molding die and a molding die that can be lowered into it.
  • a fold holder is provided which can be acted upon by the molding die, so that the individual blank to be formed is clamped between the molding die and the fold holder. This is intended to ensure that the material slips in a controlled manner during deep drawing.
  • a counter-piston which is able to press against the underside of the individual blank, is arranged opposite the forming die.
  • the DE 10 2014 106 427 A1 describes a method for producing three-dimensional molded parts from a sheet of a flat, plastically deformable fiber material with a deep-drawing device which comprises a punch and an associated die. Before reaching the deep-drawing device, a relief cut is made so that a blank for the molded part is connected to the web via at least one web and is otherwise detached from the web. In the deep-drawing device, the punch is lowered and presses the blank into a drawing sleeve. A counter holder pushes the molded part out of the draw sleeve.
  • the DE 2 226 222 A1 describes a method for erecting cardboard blanks, which consist of a bottom field and a number of side wall fields and possibly joint fields.
  • a stack of such cardboard blanks is made available in a magazine.
  • Under the magazine there is a mold with a puller located under the open bottom. This has suction holes on its surface that are connected to a vacuum source. The puller can be passed up through the open bottom of the mold to grab a carton blank and then pull it down into the mold.
  • the DE 2 008 313 A1 describes a method of folding a scored blank of paperboard into a container.
  • a blank which has an approximately rectangular shape, is moved downwards by means of a vacuum plate with a number of suction cups along an arrangement of folding elements which have rods and stops.
  • the object of the present invention is to provide a method which allows packaging to be produced from a non-thermoplastic or only slightly thermoplastic material and which can be efficiently integrated into a higher-level work process.
  • a corresponding molding tool should be specified.
  • a pre-cut sheet of material is first provided.
  • a partial area of the material sheet is incompletely punched out of the prepunched material sheet, so that the partial area is connected to a remaining area of the material sheet via a plurality of retaining lugs.
  • the incompletely punched-out part of the area should later be used for the packaging, or a part of it, form and can be shaped accordingly.
  • the packaging is to be produced, for example, as a packaging tray with a rectangular base area, the partial area can be punched out as a substantially rectangular area.
  • the packaging could be designed as a packaging tray with a round or elliptical base.
  • the retaining lugs are preferably positioned in such a way that the incompletely punched-out partial surface is held in several directions on the remaining surface of the sheet of material. In this way, the punched-out partial area remains in a defined orientation and position relative to the remaining area of the sheet of material.
  • the pre-punched sheet of material is positioned over a molding die of a molding tool, so that the incompletely punched-out partial surface of the sheet of material at least partially covers an opening of a molding recess in the molding die.
  • the recess of the molding die is designed according to the desired shape of the packaging to be produced.
  • the remaining surface of the material sheet is clamped against a contact surface of the forming die.
  • a clamping device can act on the remaining surface of the sheet of material against the contact surface of the molding die. It is possible, but not absolutely necessary, for the remaining surface of the sheet of material to actually come into contact with the forming die. It would also be conceivable that one or more intermediate elements are provided between the contact surface of the molding die and the remaining surface of the sheet of material, as long as the remaining surface of the sheet of material is immobilized at least in some areas by the clamping relative to the contact surface.
  • the incompletely punched-out partial area of the sheet of material is sucked by means of negative pressure onto an insert that can be moved vertically in the molding cavity of the molding die.
  • the height-adjustable insert is in a starting position. From the starting position, the height-adjustable insert is moved further into the mold cavity along one direction of movement. This can be done with continued suction of the partial area of the sheet of material to the height-adjustable insert.
  • the partial surface of the sheet of material is drawn into the mold recess and thus shaped into a packaging tray.
  • a sheet of material is used from which the partial area which is then used to shape the packaging is only partially made from the sheet of material is punched out. Therefore, the partial area can be fed to the molding tool together with the remaining area of the material sheet. This facilitates correct positioning over the molding die of the molding tool, even with a complicated shape of the punched-out partial surface. In particular, automated positioning over the molding die is simplified, since the remaining area of the sheet of material is available as a contact surface for holding or gripping elements.
  • the molded packaging tray in the die is more easily accessible from above and can be subjected to further processing steps directly in the die.
  • additional devices can be provided above the die, for example.
  • the retaining lugs When the height-adjustable insert is moved from the starting position further into the mold recess, the retaining lugs preferably tear off, as a result of which the partial area is separated from the remaining area of the sheet of material. Since the remaining surface of the sheet of material is clamped against the contact surface of the molding die and the partial surface of the sheet of material is sucked onto the height-adjustable insert by means of negative pressure, the retaining lugs are torn off in a controlled manner. It is generally not possible to twist the surface or the sheet of material when the retaining lugs are torn off.
  • the recess in the mold has a bevel that widens in the direction of the opening.
  • packaging trays can be formed, the side walls of which are inclined outwards in the direction of an opening in the packaging tray.
  • the draft also makes it easier for the partial surface of the sheet of material to be drawn into the depression in the shape.
  • the sheet of material it is possible for the sheet of material to be already pre-cut.
  • pre-cut sheets of material could have been obtained from a supplier or previously produced in a separate process.
  • Pre-cut sheets of material can be available separately.
  • a multiplicity of pre-punched sheets of material are present in an interconnected state, for example as a supply roll.
  • the pre-cut sheets of material could then be separated from one another before being positioned above the forming die, or a pre-cut sheet of material could be positioned above the die without prior separation from the other sheets of material.
  • the method according to the invention comprises prepunching the sheet of material.
  • the step of providing the prepunched sheet of material could then include the prepunching of the sheet of material, preferably by a punching station.
  • the partial area of the sheet of material can be punched out incompletely from the sheet of material, so that the partial area remains connected to the remaining area of the sheet of material via the multiple retaining lugs.
  • the sheet of material is already present as a separate sheet of material before the pre-punching. This could be positioned manually or automatically over the forming die after the pre-punching. However, it would also be conceivable that the sheet of material is part of a longer material web that is unrolled from a supply roll, for example. In this case, the sheet of material could first be fed to a punching station for pre-punching the sheet of material and then, for positioning the pre-punched sheet of material, be positioned by advancing the material web over the molding die of the molding tool. It would also be conceivable that a material web is fed to the punching station and the punching station separates the sheet of material from the rest of the material web at the same time as the partial area is punched out or in an additional step
  • the material of the sheet of material is preferably essentially non-thermoplastically deformable.
  • the sheet of material consists of a material which comprises components which, taken by themselves, are thermoplastically deformable. If the material of the sheet of material is not thermoplastically deformable, the tearing off of the retaining lugs can take place in a particularly controlled manner.
  • the material of the sheet of material preferably comprises natural fiber, cardboard and / or paper. In this way, inexpensive, environmentally friendly and stable packaging can be produced.
  • thermoplastic film layer is positioned over the sheet of material over the molding die.
  • the thermoplastic film layer can be molded into the packaging tray formed from the partial surface of the material sheet, so that there is no direct contact between a product to be packaged and the packaging tray later. This is particularly advantageous if the product to be packaged has moisture which would be absorbed by the packaging tray on contact.
  • the thermoplastic film layer is positioned over the sheet of material while the sheet of material is over the forming die.
  • the thermoplastic film layer can be positioned over the sheet of material before the partial surface of the sheet of material is drawn into the mold recess by moving the height-adjustable insert and the packaging tray is thus formed.
  • the packaging tray is first formed and the thermoplastic film layer is only then positioned over the sheet of material over the forming die.
  • the film layer can be positioned over the sheet of material as long as it is still on the forming die. It is therefore not necessary to move the packaging tray to a further work station before the thermoplastic film layer is applied.
  • the thermoplastic film layer is preferably formed into the packaging tray from the side of the film layer facing away from the sheet of material by using compressed air.
  • the thermoplastic film layer is acted upon by the compressed air into the packaging tray and can lie against the interior of the packaging tray.
  • the thermoplastic film layer is preferably held by the clamping device.
  • the thermoplastic film layer can already be acted upon with compressed air while the partial surface of the sheet of material is drawn into the mold recess to form the packaging tray, so that the thermoplastic film layer is shaped together with the packaging tray.
  • the film layer can be heated after positioning over the sheet of material over the forming die by means of a heating device located on the side of the film layer facing away from the forming die.
