Definitions

  • the invention relates to a method for forming closed packages, comprising the following steps: a) providing a closed package, b) providing a device for forming packages with at least two support elements and with at least two sliding elements, c) introducing the package into the room between the support elements, d) moving the slide elements from an open position to a closed position to form the packaging, e) moving the slide elements from a closed position to an open position, and f) removing the packaging from the space between the support elements.
  • an apparatus for forming closed packages comprising: a base plate for supporting the bottom or gable of the packages, at least two support elements for supporting the side surfaces or the front surface and the rear surface of the packages, and at least two sliding elements for Forming the side surfaces or the front surface and the rear surface of the packaging, the support elements and the sliding elements having at least one molding surface on their side assigned to the packaging.
  • Packaging can be made in different ways and from a wide variety of materials.
  • a widespread possibility of production consists in producing a blank that usually has fold lines (also called “crease lines”) from the packaging material, from which a packing jacket and finally a packaging is produced by folding and further steps.
  • fold lines also called “crease lines”
  • One of the advantages of this variant is that the blanks are very flat and can therefore be stacked to save space. In this way, the blanks or packaging sleeves can be produced in a different location than that The packaging sleeves are folded and filled.
  • Composites are often used as the material, for example a composite of several thin layers of paper, cardboard, plastic or metal. Such packaging is particularly popular in the food industry.
  • Packages with partially curved fold lines are, for example, from the WO 2009/141389 A2 known.
  • Devices and methods for producing such packaging are, for example, from the DE 1 187 178 A , of the EP 2 586 718 A1 , of the EP 2 586 718 A1 or the DE 10 2006 042 506 A1 known.
  • a disadvantage of these devices and methods is that only packaging with straight folded edges can be produced.
  • some of these documents provide for horizontal processing of the packaging, so that the packaging that is typically standing during filling must be rotated after closing. Occasionally, the packaging is only filled and closed in the molding device during or after the forming ( DE 10 2006 042 506 A1 ). However, this is structurally complex to implement, since aseptic or sterile conditions must often prevail when filling and closing the packaging.
  • the object of the invention is to enable the packaging to be shaped precisely, even in the case of closed packaging with complex geometry.
  • This object is achieved in a device in that at least one of the shaped surfaces is curved at least in sections.
  • a device for shaping or reshaping closed packages is shown and described.
  • This can be, for example, a food-filled packaging made of a composite material.
  • the composite material can comprise several thin layers of paper, cardboard, plastic or metal, in particular aluminum.
  • the device initially has a base plate for supporting the bottom or the gable of the packaging.
  • the packaging should therefore be able to be placed on the base plate with its base or with its gable and thus stand vertically on the base plate.
  • the device also comprises at least two support elements for supporting the side surfaces or the front surface and the rear surface of the packaging.
  • the support elements are preferably arranged at a distance from one another which corresponds approximately to the width or depth of the packaging to be supported by them.
  • the device comprises at least two sliding elements for shaping the side surfaces or the front surface and the rear surface of the packaging.
  • Sliding elements are understood to mean elements which can be moved, in particular shifted, relative to one another.
  • the support elements and the sliding elements have at least one molding surface on their side assigned to the packaging.
  • the shaped surface is understood to mean that surface which is in contact with the packaging when the packaging is formed.
  • At least one of the shaped surfaces is curved at least in sections. At least one of the shaped surfaces is preferably continuously curved.
  • the curvature can be concave or convex, for example.
  • the curvature of one or more shaped surfaces can also be both concave and convex, so that, for example, the concave and convex regions of a shaped surface are arranged side by side or adjacent.
  • the curved shaped surfaces can be shaped surfaces of the support elements and / or shaped surfaces of the sliding elements. Due to the curvature of the shaped surfaces, packaging with complex geometry can also be formed. These are especially packaging where not all of the folding lines are straight. In front All such folding lines often do not get their final, ready-to-sell shape through a single fold, but require a new shaping.
  • all the shaped surfaces of the support elements and / or all the shaped surfaces of the sliding elements are curved at least in sections. Since not only one molded surface, but all molded surfaces of the support elements and / or the sliding elements are curved at least in sections, packaging with a particularly complex geometry can also be reliably molded. In particular, packaging can be formed in which complex shapes are to be achieved on several sides of the packaging.
  • the support elements are rigidly connected to the base plate.
  • the distance between the two support elements can be set particularly precisely by connecting both support elements to the same base plate.
  • the support elements can be detachably connected to the base plate so that they can be replaced. This has the advantage that different packages can be formed on the same device.
  • a rigid connection is therefore understood to mean a connection which is immobile in the undissolved state, that is to say in the operating state.
  • the sliding elements are movably connected to the base plate.
  • the direction of movement and the movement path of both sliding elements can be set particularly precisely. It can also be ensured that the two sliding elements run approximately at right angles to the base plate.
  • the sliding elements can be detachably connected to the base plate so that they can be replaced. This has the advantage that different packages can be formed on the same device.
  • the sliding elements are movably mounted in guides which are provided in the base plate.
  • a particularly precise movement can be achieved by mounting the sliding elements in guides.
  • the guides are preferably linear. It can be provided that the guides of two opposite sliding elements are arranged on the same axis, that is to say they run collinearly. In this way, the opposing compressive forces compensate each other when the packaging is formed, so that no torques arise.
  • a further embodiment of the device is characterized by at least four support elements for supporting the side surfaces or the front surface and the rear surface of the packaging. Thanks to an increased number of support elements, the packaging can be held in its position even more precisely during molding. For example, an edge or a side surface of the packaging can be assigned to each of the four support elements.
  • a further embodiment of the device is characterized by at least four sliding elements for shaping the side surfaces or the front surface and the rear surface of the packaging.
  • the packaging can be shaped even more precisely by an increased number of sliding elements. For example, an edge or a side surface of the packaging can be assigned to each of the four sliding elements.
  • it makes sense if at least one section (area) of an edge and at least one section (area) of a side face of the packaging are assigned to a sliding element.
  • two support elements are arranged on opposite sides of the packaging.
  • the opposite arrangement of the support elements ensures that the packaging is fixed on both sides, which enables the packaging to be positioned precisely.
  • Two support elements arranged opposite one another can thus fix the packaging in one direction of movement.
  • Four support elements arranged opposite one another can thus fix the packaging in two directions of movement. If four support elements are provided, these are preferably aligned at an angle of approximately 90 ° to one another, so that they surround the packaging evenly.
  • Another embodiment of the device provides that two sliding elements are arranged on opposite sides of the packaging. Due to the opposite arrangement of the sliding elements, the packaging can be pressurized on both sides. Preferably, two of the sliding elements are oriented in opposite directions and are arranged on the same axis; so they are collinear. In this way, the opposing compressive forces compensate each other when the packaging is formed, so that no torques arise.
  • a stop surface is provided on at least one support element and / or on at least one sliding element, which is arranged such that it serves as a stop for the sliding elements.
  • the stop surfaces are intended to prevent the sliding elements from being pushed too far between the supporting elements and thereby damaging or crushing the packaging.
  • the stop surfaces therefore serve to precisely limit the path of the sliding elements. Stop surfaces can be achieved, for example, in that the sliding elements are at least at one point somewhat wider than the gap between the two adjacent support elements. The provision of stop surfaces also simplifies the drive of the sliding elements.
  • the object described above is achieved according to the invention by a method for forming closed packages.
  • the method comprises the following steps: a) providing a closed package, b) providing a device for forming packages with at least two support elements and with at least two slide elements, c) inserting the package into the space between the support elements, d) moving the slide elements from an open position to a closed position for forming the packaging, e) moving the sliding elements from a closed position to an open position, and f) removing the packaging from the space between the support elements.
  • the packaging formed by the method can, for example, be packaging made of a composite material and filled with food.
  • the composite material can comprise several thin layers of paper, cardboard, plastic or metal, in particular aluminum.
  • the method is characterized in that the packaging is formed by shaped surfaces, at least one of which is curved at least in sections. At least one of the shaped surfaces is preferably continuously curved.
  • the curvature can be concave or convex, for example.
  • the curvature of one or more shaped surfaces can also be both concave and convex, so that, for example, the concave and convex regions of a shaped surface are arranged side by side or adjacent.
  • the curved shaped surfaces can be shaped surfaces of the support elements and / or shaped surfaces of the sliding elements.
  • packaging with complex geometry can also be shaped by the curvature of the shaped surfaces. These are especially packaging where not all of the folding lines are straight. Such folding lines in particular often do not get their final, ready-to-sell shape from a single fold, but rather need to be shaped again.
  • step b) a device according to one of the previously described configurations or developments is provided. Due to the at least sectionally curved shaped surfaces, the device described above is particularly suitable in all the illustrated embodiments for carrying out the method.
  • a further embodiment of the method provides that the packaging in steps d) and e) stand vertically on its base area or on its gable area.
  • the vertical orientation of the packaging has the advantage that the packaging no longer has to be rotated - for example put on its side - after filling and closing. This is because most packaging is filled either through the (still unsealed) bottom area or through the (still unsealed) gable area. Due to the omitted rotary movements, the contents of the packaging are protected, which is particularly desirable for sensitive contents.
  • the sliding elements are shifted from an open position into a closed position until they collide with the support elements on the stop surfaces.
  • Limiting the displacement by a stop is a structurally simple way to prevent damage to the packaging.
  • a particular advantage is that the drive of the sliding elements is simplified by the stop surfaces. This is because the displacement of the sliding elements is limited by the stop surfaces, so that the (for example electrical or hydraulic or pneumatic) drive of the sliding elements itself does not have to have a path limitation. This has the advantage that the same drive can be used with different packaging (and with different sliding elements and / or support elements) without having to be exchanged or adjusted.
  • the packaging in particular the gable area of the packaging, is arched outwards in the closed position of the sliding elements.
  • the volume remaining in the closed position between the sliding elements should be somewhat less than the volume of the closed packaging.
  • the packaging of the compression must be able to "dodge" the sliding elements, which is why one side of the packaging - preferably the upper side, that is to say the gable area - should not be touched and deformed by the sliding elements. Instead, there should be a free space on this side of the packaging that allows the packaging to curve outwards - that is, a convex curvature. The packaging should therefore be deformed beyond its ready-to-sell shape. This measure compensates for the resetting behavior of the packaging material.
  • Fig. 1A shows a blank 1 for folding a packaging jacket.
  • the blank 1 can comprise several layers of different materials, for example paper, cardboard, plastic or metal, in particular aluminum.
  • the blank 1 has a plurality of fold lines 2, which are intended to facilitate the folding of the blank 1 and divide the blank 1 into a plurality of areas.
  • the blank 1 can be divided into a first side surface 3, a second side surface 4, a front surface 5, a rear surface 6, a sealing surface 7, floor surfaces 8 and gable surfaces 9.
  • the bottom surfaces 8 and the gable surfaces 9 each comprise rectangular surfaces 10 and triangular surfaces 11.
  • a packing jacket can be formed from the blank 1 by folding the blank 1 in such a way that the sealing surface 7 can be connected, in particular welded, to the front surface 5.
  • the four large surfaces (ie the two side surfaces 3, 4, the front surface 5 and the rear surface 6) of the in Fig. 1 blank 1 shown are not separated from each other by a straight fold line 2; instead, the four large surfaces 3, 4, 5, 6 are separated from one another by two curved fold lines 2 ', between each of which a free-form surface 12 is arranged.
  • the two side surfaces 3, 4 of the blank 1 each have a false fold line 13.
  • the two false fold lines 13 are straight and run parallel to one another.
  • the false fold lines 13 run through a contact point SB of three adjacent triangular surfaces 11 of the base surface 8 and through a contact point SG of three adjacent triangular surfaces 11 of the gable surfaces 9.
  • the bottom surfaces 8 of the in Fig. 1A blank 1 shown have four corner points E8 and the gable surfaces 9 have four corner points E9.
  • the corner points E8, E9 represent corner points of the packaging to be produced from the blank 1.
  • Each corner point E8 of a floor surface 8 is assigned a corresponding corner point E9 of a gable surface 9, which is the corner point E9 which is above this corner point when the packaging is standing E8 is arranged.
  • Divided by two Corner points E8, E9 assigned to one another run a corner axis EA, which would correspond to a vertical packaging edge in the case of conventional cuboid packaging.
  • Figure 1B is a packing jacket 14, which from the in Fig. 1A shown blank 1 is formed, shown in a flat view in a front view.
  • the already related to Fig. 1A Areas of the packaging jacket described are in Figure 1B provided with corresponding reference numerals.
  • the packaging jacket 14 is produced from the blank 1 in two steps: First, the blank 1 is folded along the two false fold lines 13. The two partial areas 6A, 6B of the divided rear surface 6 are then connected to one another in the area of the sealing surface 7, in particular welded, as a result of which a (in Figure 1B hidden) longitudinal seam 15 arises.
  • the packing jacket 14 thus has a circumferential, closed structure in the circumferential direction with an opening in the region of the bottom surface 8 and with an opening in the region of the gable surface 9.
  • the edge of the longitudinal seam 15 running within the packaging jacket 14 is covered.
  • the purpose of covering the open cut edge of the composite is to avoid contact between the contents of the packaging and this layer, in particular the paper or cardboard layer contained therein.
  • the cutting edge is covered here by folding over the composite layer after previous peeling.

  • the already related to 1A to 1C Areas of the packaging jacket described are in Figure 1D provided with corresponding reference numerals.
  • the unfolded state can be achieved by several folding steps: First, the packaging jacket 14 is folded along the fold lines 2 ′, which are arranged between the four large areas 3, 4, 5, 6 and the four open areas 12. Secondly, the packing jacket 14 is refolded along the false fold lines 13 running through the side surfaces 3, 4. The refolding takes place by approximately 180 °.
  • the refolding along the false fold lines 13 has the result that the two partial regions 3A, 3B of the first side surface 3 adjoining the false fold line 13 no longer lie on one another, but are at least arranged approximately in the same plane.
  • the refolding along the dummy fold lines 13 has the result that the two subregions 4A, 4B of the second side face 4 adjoining the dummy fold line 13 no longer lie on one another, but are at least approximately in the same plane.
  • the packing jacket 14 is therefore only in its flat state ( 1B, 1C ) folded along the false fold lines 13; when unfolded ( Figure 1D ) the packing jacket 14 (as well as the packaging to be produced therefrom) is no longer folded along the false fold lines 13. Hence the designation "Schein" fold lines 13.

  • FIG. 1F also shows a package 17, which from the in Figure 1B Packing jacket 14 shown is formed after welding. Corresponding reference numerals are therefore also used here.
  • the difference to Figure 1F lies in the fact that the triangular surfaces 11 in the bottom area of the packaging were not folded outwards before welding, but inwards. Therefore, the "ears" 14 in the bottom area of the packaging do not protrude outwards, but extend inwards. This leads to a shorter fin seam 18.
