Definitions

  • the invention relates to a method for erecting a package from a one-piece cardboard blank or the like, with a bottom portion and two side walls, which are connected to one another by sealing edge strips, and to an apparatus for carrying out the method.
  • the invention is based on the object of proposing a method and a device with which the packaging can be produced efficiently and in large numbers.
  • This object is achieved in that in a first stage the bottom section is clamped between two molds and the side walls are bent upwards by approximately 90 °, that end walls are then folded out from the side walls and connected by means of the sealing edge strips, that subsequently the are joined together sealed sealing edge strips are placed on the end walls and fixed there, and that the gusset areas separated from the end walls and the bottom section during erection are placed on the outside of the bottom section and fixed there.
  • An advantageous device for performing this method is characterized according to the invention in that a plurality of shaping mandrels (2) are provided on a carousel (1), each of which is assigned to a processing station, the carton blank being fed from a stack of stocks in the first processing station and between the shaping mandrel and a die arranged underneath is provided with a hollow bottom and at the same time the two side walls are folded upwards by 90 °, that four rotatably mounted flaps are provided in the second processing station, which fold the end walls off the side walls and thereby place the sealing edge strips on top of each other in that third processing station sealing tools are provided which seal the sealing edge strips together that spray nozzles or the like in the fourth processing station for applying hot melt.
  • FIG. 1 in FIG. 1 denotes a carousel, which is equipped with eight completely identical mandrels 2, each of which is assigned to a processing station I to VII.
  • the processing station I is assigned a feed device 3, via which flat cardboard blanks 4 are fed.
  • a cardboard blank is sucked out of a stack of stock 5 and placed on the feed device. This transports the cardboard blank 4 to such an extent that it lies centrally under the mandrel 2.
  • a shaping punch 6 is arranged under the shaping mandrel 2, which can be raised and presses the carton blank against the shaping mandrel 2 during this raising.
  • the bottom section 7 of the cardboard blank 4 is bent upwards, as can be seen in FIG. 2.
  • two flaps 8 and 9 ripen on the cardboard blank, which fold its side walls upwards by 90 °, as can also be seen in FIG. 2.
  • the cardboard blank so erected is then transported together with the shaping mandrel to the processing station II, in which four rotatably mounted flaps 10, 11 are provided, which move the end walls of the packaging from the side walls Unfold 90 °, the sealing edge strips protruding vertically from the end walls.
  • the processing station III contains — as shown in FIG. 3 — on the underside two flaps 16 which place the gusset surfaces projecting downward on the underside of the bottom section of the packaging.
  • the finished packaging is pushed off the mandrel 2 and transported away on a conveyor belt 17, not shown.
  • Station VIII only functions as an intermediate station in which no processing takes place.
