Definitions

  • the present invention relates to the field of producing packaging, in particular packaging, which are at least partially made of a substantially non-thermoplastically deformable material.
  • a device for deep drawing a carton blank is known in a cup or cup-shaped object.
  • a punching device individual blanks are completely punched out of a board web.
  • the punched individual blanks are then fed to forming a forming station.
  • the forming station comprises a forming die and a mold die which can be lowered into it.
  • a pleat holder is provided, which can be acted upon on the forming die, so that the individual blank to be formed is clamped between the forming die and the pleat holder. This is to ensure a controlled slipping of the material during deep drawing.
  • an opposing piston is arranged, which is able to press against the underside of the single blank.
  • a corresponding mold should be specified.
  • a pre-cut sheet of material is first provided. From the pre-cut material sheet, a partial surface of the material sheet is incompletely punched, so that the partial surface is connected via a plurality of retaining lugs with a residual surface of the material sheet.
  • the incompletely punched part surface is later the packaging, or a part thereof, form and can be shaped accordingly.
  • the packaging is to be produced, for example, as a packaging tray having a rectangular base area, the partial area can be punched out as a substantially rectangular area. But there are also other shapes conceivable.
  • the package could be formed as a packaging tray having a round or elliptical base.
  • the retaining lugs are positioned so that the incompletely punched part surface is held in several directions on the remaining surface of the sheet of material.
  • the punched-out part surface remains in a defined orientation and position relative to the remaining surface of the material sheet.
  • the pre-cut material sheet is positioned over a forming die of a forming tool so that the incompletely punched-out part surface of the material sheet at least partially covers an opening of a forming recess of the forming die.
  • the mold cavity of the forming die is designed according to the desired shape of the packaging to be produced.
  • the remainder of the sheet of material is clamped against an abutment surface of the forming die.
  • a clamping device act on the remaining surface of the sheet of material against the contact surface of the forming die. It is possible, but not essential, that the remainder of the sheet of material actually comes into contact with the forming die. It would also be conceivable for one or more intermediate elements to be provided between the contact surface of the forming die and the remaining surface of the material sheet as long as the remaining surface of the material sheet is at least partially immobilized relative to the contact surface by clamping.
  • the incompletely punched-out part surface of the sheet of material is sucked by means of negative pressure to a height-movable in the mold cavity of the mold cavity insert.
  • the height-adjustable insert is in a starting position. From the start position, the height-adjustable insert is moved further along the direction of travel into the mold cavity. This can be done with continued suction of the partial surface of the sheet of material to the height-adjustable insert.
  • the partial surface of the material sheet is hereby drawn into the mold cavity and thus formed into a packaging tray.
  • a sheet of material is used from which the partial surface, which is subsequently used to form the packaging, only incompletely from the sheet of material punched out. Therefore, the partial surface can be supplied to the mold together with the remaining surface of the sheet of material. This facilitates correct positioning over the forming die of the molding tool, even with complicated shaping of the punched out face. In particular, an automated positioning over the forming die is simplified, since the remaining surface of the material sheet 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. For this purpose, for example, additional devices may be provided above the die.
  • the retaining lugs in the process of height-adjustable insert from the starting position further into the mold cavity tear the retaining lugs, whereby the partial surface is separated from the remaining surface of the material sheet. Since the remaining surface of the material sheet is clamped against the contact surface of the forming die and the partial surface of the sheet of material is sucked by vacuum to the height-adjustable insert, the tearing of the retaining lugs takes place in a controlled manner. Twisting the partial surface or the material sheet when tearing off the retaining lugs is generally not possible.
  • the molding recess of the molding die preferably has a draft which widens in the direction of the opening.
  • the side walls are inclined in the direction of an opening of the packaging shell outwards. Due to the draft, the pulling in of the partial surface of the material sheet into the mold cavity is also facilitated.
  • pre-cut sheets of material could be sourced from a supplier or previously manufactured in a separate process. Pre-cut sheets of material can each be available separately. However, it would also be conceivable, for example, for a multiplicity of pre-cut material sheets to be in an interconnected state, for example as a supply roll. The pre-cut sheets of material could then be separated from one another prior to positioning over the forming die, or a pre-cut sheet of material could be positioned over the die without prior separation from the remaining sheets of material.
  • the method according to the invention comprises the pre-punching of the material sheet.
  • the step of providing the pre-cut sheet of material could then include pre-punching the sheet of material, preferably by a stamping station.
  • the partial surface of the material sheet can be incompletely punched out of the material sheet, so that the partial surface remains connected via the plurality of retaining lugs with the remaining surface of the material sheet.
  • the material sheet is already present as a separate material plate before the pre-punching. This could be positioned manually or automatically above the forming die after pre-punching. It would also be conceivable that the material sheet is part of a longer material web, which is for example unrolled from a supply roll. In this case, the material sheet could first be fed to a stamping station for pre-piercing the sheet of material and then positioned to position the pre-cut sheet of material by advancing the web over the forming die of the forming tool. It would also be conceivable for the stamping station to be fed with a material web and for the stamping station to separate the material sheet from the remainder of the material web at the same time as the blank surface is blanked out or in an additional step
  • the material of the material sheet is substantially not thermoplastically deformable.
  • the material sheet consists of a material which comprises constituents which, taken alone, are thermoplastically deformable. If the material of the material sheet is not thermoplastically deformable, the tearing of the retaining lugs can be carried out in a particularly controlled manner.
  • the material of the material sheet preferably comprises natural fiber, cardboard and / or paper. This allows cost-effective, environmentally friendly and stable packaging to be produced.
  • thermoplastic film layer is positioned over the material sheet over the molding die.
  • the thermoplastic film layer can be molded into the packaging tray formed from the partial surface of the sheet of material so that later there is no direct contact between a product to be packaged and the packaging tray. This is particularly advantageous when the product to be packaged has moisture which would be absorbed by the packaging tray upon 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 attracted by moving the height-adjustable insert into the mold cavity, thus forming the packaging shell.
  • the packaging shell to first be formed, and for the thermoplastic film layer to be positioned above the material sheet above the molding 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 spend the packaging tray in another workstation before the thermoplastic film layer is applied.
  • the thermoplastic film layer is preferably shaped into the packaging shell by means of an application of compressed air from the side of the film layer facing away from the material sheet.
  • the thermoplastic film layer is acted upon in the packaging shell and can invest in the interior of the packaging tray.
  • the thermoplastic film layer is held by the clamping device.
  • the thermoplastic film layer can already be acted upon with compressed air, while the part surface of the sheet of material is drawn into the mold cavity for forming the packaging shell, so that the thermoplastic film layer is brought into the same shape together with the packaging shell.
  • the film layer can be heated after being positioned above the material sheet above the molding die by means of a heating device located on the side of the film layer facing away from the molding die.
  • the heating device can in particular be movable parallel to the direction of travel of the height-adjustable insert.
  • the heater can be moved away from the forming die to a stowed position. After positioning the thermoplastic Film layer, the heater can be moved from the stowed position in the direction of the forming die out in a heating position to heat the thermoplastic film layer.
  • the invention further relates to a molding tool for producing a packaging from a material sheet which has been pre-punched by incomplete punching a partial surface of the material sheet such that the partial surface remains connected to a residual surface of the material sheet via a plurality of retaining lugs.

  • the molding tool comprises a clamping device, which is designed to clamp the remaining surface of the material sheet against the contact surface of the forming die, when the pre-cut material sheet is positioned over form die so that the partial surface of the material sheet at least partially covers the opening of the mold cavity of the forming die.
  • a height-adjustable insert is provided, which can be moved further out of a starting position along a direction of travel into the mold cavity.
  • the mold also comprises a vacuum device, to which e.g.
  • a vacuum pump can be applied by means of a vacuum pump and which is designed to suck the partial surface of the sheet of material by means of negative pressure to the height-adjustable insert.
