Definitions
- the invention relates to a device for shaping the gable surfaces of
- Angled gable packaging comprising: a conveyor having cells attached thereto for receiving the packages, at least one gable folder for folding a fin seam in the gable area of the packages, and at least two earmolds for folding ears in the gable area of the packages.
- the invention also relates to a method for forming the gable surfaces of oblique gable packages, comprising the following steps: a) providing packages with sloping gables, b) folding the fin seam in the gable area of the packages through a gable folder, and c) folding the ears in the Gable area of the packaging by two ear-butterflies.
- Packaging can be done in different ways and in different ways
- Packages which are produced from blanks are known, for example, from WO 2009/141389 A2 and DE 38 35 390 A1. These packages have predominantly gable surfaces which rise on both sides at an identical angle to the center and are thus symmetrically shaped. Therefore, the fin seam forms - at least before it is folded - the highest point of the packaging.
- Cuttings can also be used to produce packages with asymmetrical gables - in other words oblique gables.
- packages are known, for example, from WO 2009/030910 A2 and from EP 2 468 641 B1.
- the creation of protruding areas is particularly difficult, since in such inclined gable packaging often not the fin seam, but the trailing edge of the gable forms the highest point of the package. As a result, the fin seam is more difficult to access for tools.
- the fin seam in such packaging can not be created by a fixed tool on which the packaging is passed.
- the packaging is formed on a rotatable mandrel wheel with several stations.
- the folding of the ears takes place initially by fixed rails, past which the packages are passed, and then by means of movable folding tools.
- the fin seam in the gable area of the packaging is folded over by pushing the packaging with the gable ahead between two fixed supports until the fin seam abuts against a likewise fixed and oblique stop and is folded over (paragraph [0068]).
- a disadvantage of this procedure lies in the high
- the invention is based on the object, also in
- Packaging with sloping gables to allow fast and reliable shaping of the gable This object is achieved in a device according to the preamble of patent claim 1, characterized in that both the gable and the ear moth are movably mounted relative to the conveyor and the packaging transported therewith.
- the device is a device for molding the
- the packaging is preferably a food packaging made from a composite material.
- the composite material may comprise a plurality of thin layers of paper, cardboard, plastic or metal.
- the device initially comprises a conveyor with cells attached thereto for receiving the packages.
- Conveyor for example, a conveyor belt, a conveyor belt or a transport chain
- high tensile forces can be transmitted, which allow a plurality of packing coats at constant intervals to each other
- the cells serve to accommodate the packaging coats.
- Packungsmäntel can be held both by a positive connection and by a non-positive connection in the cells.
- Conveyor is preferably arranged in a horizontal plane.
- the device also comprises at least one gable folder for folding a
- the gable folder centrally above the conveyor and the packages transported thereon.
- the device comprises at least two earflaps for folding ears in the gable area of the packages.
- the two are
- Packaging arranged on both sides next to the pediment.
- Packaging are movably mounted.
- the pediment and the ear-butterfly should be rotatable, pivotable, displaceable or otherwise movably mounted.
- Another advantage is that can be formed by movably mounted folding tools and packaging, where not the fin seal, but the rear edge of the gable form the highest point of the packaging.
- the folding tools can also be used to form other areas of the gable, such as the curved leading edge of the gable, in addition to flipping the fin seam and engaging the ears.
- the gable folder is movably mounted in a plane, in particular in a plane through the
- the gable-hair folder should not be able to be displaced linearly, but should have an at least two-dimensional mobility.
- the giebelfalter perform translation movements, rotational movements or combinations of both (superimposition of translational and rotational movements).
- Another embodiment of the device provides that the ear moths are movably mounted in a plane, in particular in a plane through the
- the moths should not be able to be moved linearly, but have an at least two-dimensional mobility.
- the earflaps can perform translational movements, rotational movements, or combinations of both (superposition of translation and translation)
- the plane of movement of the earflaps is formed by the vertical direction and the transverse direction of the packages.
- the gable folder is arranged between the two ear folds.
- the gable folder and the ear folders are arranged above the conveyor and the packages transported thereon.
- a particularly compact design is achieved. This is particularly advantageous in installations where multiple parallel rows of packages are processed simultaneously.
- the gable can reliably transfer the fin seam even if it does not cover the entire width of the fin seam, but about the width of the packaging (without protruding ears) covers.
- Floss seam in the gable area of the packaging can move in the direction of the transport direction of the packaging. This should also be possible if the sloping gables of the packaging increase in the direction of transport; the This is achieved constructively in that the gable folder is not only movable in the vertical direction, but is also movably mounted in the direction of transport of the packages Movement component in the direction of the transport direction of the packaging have to be able to move the fin seam in this direction.
- a further embodiment of the device is characterized by at least two, in particular at least four gable folders for folding a fin seam in the gable area of the packages, and at least four, in particular at least eight, ear folds for folding ears in the gable area of the packages, wherein one gable folder and two ear folders each form a unit to form a packaging.
- a plurality of packages can be processed simultaneously.
- a plurality of parallel conveyor belts may be provided.
- each row of packages to be processed is associated with a gable-folder and two ear-trap unit.
- a unit is meant a group of folding tools arranged to handle the same package.
- All gables should therefore be connected to each other, for example by a common rail, to which all gables are attached. Likewise, everyone should
- Earflaps be interconnected; This can also be done by attachment to a common rail.
- the connection of the gables has the advantage that all gables can be moved synchronously by a common drive. Likewise, all earflaps can be moved synchronously due to their connection by a common drive.
- the object described at the beginning is also achieved by a method for shaping the gable surfaces of packages with an inclined gable. The method comprises the following steps: a) providing packages with sloping gables, b) folding the fin seam in the gable area of the packages through a gable folder, and c) folding the ears in the gable area of the packages by two ear moths.
- the method is characterized in that in steps b) and c) both the gable folder and the ear folders are moved relative to the conveyor and the packages transported therewith.
- the provision of the packages can be carried out in particular by a conveyor in the form of a conveyor belt or a conveyor belt or a transport chain with cells attached thereto for receiving the packages.
- Transport belt or the transport chain is preferably arranged in a horizontal plane. As already described in connection with the device, the required relative to the shaping relative movement between the
- Folding tools ie the gable and the earfolds
- the packaging by a movement of the folding tools and not by a movement of the
- Packaging can be achieved. This has the consequence that the packaging does not need to be moved during the shaping, which enables an intermittent, cyclic operation of the conveyor. Shaping at rest
- Packaging has the advantage that the filling can be carried out at a standstill packaging and also allows the processing of packaging, where not the fin seam, but the rear edge of the pediment, the highest point of the
- Form packaging Preferably, the method is carried out with a device according to one of claims 1 to 7.
- the packages are moved by a conveyor with cells attached thereto.
- a conveyor for example, a conveyor belt, a
- Conveyor belt or a transport chain high tensile forces are transmitted, which allow a plurality of packing coats at constant intervals to each other transport.
- the cells serve to accommodate the packaging coats.
- Packungsmäntel can be held both by a positive connection and by a non-positive connection in the cells.
- Conveyor is preferably arranged in a horizontal plane.
- the packages are moved intermittently.
- An intermittent, that is, tact-wise operation has the advantage that the packaging is temporarily stopped and can be processed more precisely in this phase.
- Another advantage is that the tools that handle the packages do not need to be moved along with the packages.
- a further embodiment of the method provides that the packages stand still during step b) and during step c).
- the steps b) and c) are used to flip the fin seam and create the protruding ears. These steps should be carried out as precisely and quickly as possible without damaging or deforming the packaging. These requirements can be included
- step b) provision is made for step b) to be carried out before step c).
- step b) and step c) overlap in time.
- the fin seam is folded over (step b) before the ears are applied to the package (step c).
- Movement component in the direction of the transport direction of the packaging have to be able to move the fin seam in this direction.
- the gable surfaces of at least two, in particular of at least four packages are formed simultaneously.
- a plurality of parallel conveyor belts may be provided.
- each row of packages to be processed is associated with a gable-folder and two ear-trap unit.
- Under a unit is a group of
- Folding tools understood that are arranged so that they can handle the same packaging.

Description
Vorrichtung und Verfahren zum Formen der Giebelflächen von Verpackungen mit schrägem Giebel Apparatus and method for forming the gable surfaces of packages with sloping gables
Die Erfindung betrifft eine Vorrichtung zum Formen der Giebelflächen von The invention relates to a device for shaping the gable surfaces of
Verpackungen mit schrägem Giebel, umfassend: eine Fördereinrichtung mit daran befestigten Zellen zur Aufnahme der Verpackungen, wenigstens einen Giebelfalter zum Falten einer Flossennaht im Giebelbereich der Verpackungen, und wenigstens zwei Ohrenfalter zum Falten von Ohren im Giebelbereich der Verpackungen. Angled gable packaging comprising: a conveyor having cells attached thereto for receiving the packages, at least one gable folder for folding a fin seam in the gable area of the packages, and at least two earmolds for folding ears in the gable area of the packages.
Die Erfindung betrifft zudem ein Verfahren zum Formen der Giebelflächen von Verpackungen mit schrägem Giebel, umfassend die folgenden Schritte: a) Bereitstellen von Verpackungen mit schrägen Giebeln, b) Falten der Flossennaht im Giebelbereich der Verpackungen durch einen Giebelfalter, und c) Falten der Ohren im Giebelbereich der Verpackungen durch zwei Ohrenfalter. Verpackungen können auf unterschiedliche Weisen und aus verschiedensten The invention also relates to a method for forming the gable surfaces of oblique gable packages, comprising the following steps: a) providing packages with sloping gables, b) folding the fin seam in the gable area of the packages through a gable folder, and c) folding the ears in the Gable area of the packaging by two ear-butterflies. Packaging can be done in different ways and in different ways
Materialien hergestellt werden. Eine weit verbreitete Möglichkeit der Herstellung besteht darin, aus dem Verpackungsmaterial einen üblicherweise Faltlinien (auch „Rilllinien" genannt) aufweisenden Zuschnitt herzustellen, aus dem durch Falten und weitere Schritte zunächst ein Packungsmantel und schließlich eine Verpackung entsteht. Diese Variante hat unter anderem den Vorteil, dass die Zuschnitte sehr flach sind und somit platzsparend gestapelt werden können. Auf diese Weise können die Zuschnitte bzw. Packungsmäntel an einem anderen Ort hergestellt werden als die Faltung und Befüllung der Packungsmäntel erfolgt. Als Material werden häufig Verbundstoffe eingesetzt, beispielsweise ein Verbund aus mehreren dünnen Lagen aus Papier, Pappe, Kunststoff oder Metall. Derartige Verpackungen finden Materials are produced. A widespread possibility of production consists in producing from the packaging material a blank usually having fold lines (also called "creasing lines"), from which, by folding and further steps, first a packing jacket and finally a packaging is produced. In this way, the blanks or packing shells can be produced in a different location than the folding and filling of the packaging shells takes place.As a material often composites are used, for example, a composite of several thin Layers of paper, cardboard, plastic or metal
insbesondere in der Lebensmittelindustrie große Verbreitung. Verpackungen, die aus Zuschnitten hergestellt werden, sind beispielsweise aus der WO 2009/141389 A2 und der DE 38 35 390 AI bekannt. Diese Verpackungen weisen überwiegend Giebelflächen auf, die beidseitig unter einem identischen Winkel zur Mitte hin ansteigen und somit symmetrisch geformt sind. Die Flossennaht bildet daher - jedenfalls bevor sie umgeklappt wird - die höchste Stelle der Verpackung. especially in the food industry. Packages which are produced from blanks are known, for example, from WO 2009/141389 A2 and DE 38 35 390 A1. These packages have predominantly gable surfaces which rise on both sides at an identical angle to the center and are thus symmetrically shaped. Therefore, the fin seam forms - at least before it is folded - the highest point of the packaging.
Bei der Herstellung derartiger Verpackungen liegt eine Herausforderung darin, abstehende Bereiche wie Nähte oder„Ohren" an die Verpackung anzulegen. Bei quaderförmigen Verpackungen ist dies noch recht einfach möglich; eine Maschine hierzu ist beispielsweise aus der EP 0 061 663 A2 bekannt. One challenge in the production of such packages is to apply protruding areas such as seams or "ears" to the packaging, which is still quite possible with parallelepiped packages, a machine for which is known, for example, from EP 0 061 663 A2.
Aus Zuschnitten können auch Verpackungen mit asymmetrischem - also insgesamt schrägem - Giebel hergestellt werden. Derartige Verpackungen sind beispielsweise aus der WO 2009/030910 A2 und aus der EP 2 468 641 Bl bekannt. Bei diesen Verpackungen gestaltet sich das Anlegen von abstehenden Bereichen besonders schwierig, da bei derartigen Schräggiebelverpackungen oft nicht die Flossennaht, sondern die hintere Kante des Giebels die höchste Stelle der Verpackung bildet. Dies führt dazu, dass die Flossennaht für Werkzeuge schwieriger zugänglich ist. Cuttings can also be used to produce packages with asymmetrical gables - in other words oblique gables. Such packages are known, for example, from WO 2009/030910 A2 and from EP 2 468 641 B1. In these packages, the creation of protruding areas is particularly difficult, since in such inclined gable packaging often not the fin seam, but the trailing edge of the gable forms the highest point of the package. As a result, the fin seam is more difficult to access for tools.
Insbesondere kann die Flossennaht bei derartigen Verpackungen nicht durch ein feststehendes Werkzeug angelegt werden, an dem die Verpackung vorbeigeführt wird. In particular, the fin seam in such packaging can not be created by a fixed tool on which the packaging is passed.
In der EP 2 468 641 Bl erfolgt die Formgebung der Verpackung auf einem drehbaren Dornrad mit mehreren Stationen. Die Faltung der Ohren erfolgt zunächst durch feststehende Schienen, an denen die Verpackungen vorbeigeführt werden und anschließend durch bewegliche Faltwerkzeuge. Die Flossennaht im Giebelbereich der Verpackung wird dadurch umgelegt, dass die Verpackung mit dem Giebel voran zwischen zwei feststehende Stützen geschoben wird, bis die Flossennaht an einen ebenfalls feststehenden und schräg verlaufenden Anschlag stößt und dabei umgefaltet wird (Abs. [0068]). Ein Nachteil dieser Vorgehensweise liegt in dem hohen In EP 2 468 641 B1, the packaging is formed on a rotatable mandrel wheel with several stations. The folding of the ears takes place initially by fixed rails, past which the packages are passed, and then by means of movable folding tools. The fin seam in the gable area of the packaging is folded over by pushing the packaging with the gable ahead between two fixed supports until the fin seam abuts against a likewise fixed and oblique stop and is folded over (paragraph [0068]). A disadvantage of this procedure lies in the high
konstruktiven Aufwand. Denn die bereits befüllten und verschlossenen Verpackungen müssen allein zum Zwecke der Formgebung von einem speziell zu diesem Zweck vorgesehenen Dornrad befördert werden. Ein weiterer Nachteil liegt darin, dass die meisten Faltvorgänge an feststehenden Faltwerkzeugen stattfinden, an denen die Verpackung vorbeigeführt wird. Dies führt zu ungewünschten Beschleunigungen der Verpackung und ihres empfindlichen Inhalts. constructive effort. Because the already filled and sealed packaging must be solely for the purpose of shaping of a specially for this purpose be provided mandrel wheel. Another disadvantage is that most folding operations take place on fixed folding tools, where the packaging is passed. This leads to unwanted accelerations of the packaging and its delicate content.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, auch bei Against this background, the invention is based on the object, also in
Verpackungen mit schrägem Giebel eine schnelle und zuverlässige Formung des Giebels zu ermöglichen. Diese Aufgabe wird bei einer Vorrichtung nach dem Oberbegriff von Patentanspruch 1 dadurch gelöst, dass sowohl der Giebelfalter als auch die Ohrenfalter relativ zu der Fördereinrichtung und den damit transportierten Verpackungen beweglich gelagert sind. Bei der Vorrichtung handelt es sich um eine Vorrichtung zum Formen der Packaging with sloping gables to allow fast and reliable shaping of the gable. This object is achieved in a device according to the preamble of patent claim 1, characterized in that both the gable and the ear moth are movably mounted relative to the conveyor and the packaging transported therewith. The device is a device for molding the
Giebelflächen von Verpackungen mit schrägem Giebel, insbesondere mit durchgehend schrägem Giebel. (Um-) Geformt werden insbesondere die Flossennaht und die Ohren im Giebelbereich der Verpackung. Bei der Verpackung handelt es sich vorzugsweise um eine Verpackung für Nahrungsmittel, die aus einem Verbundmaterial hergestellt ist. Das Verbundmaterial kann mehrere dünne Lagen aus Papier, Pappe, Kunststoff oder Metall aufweisen. Die Vorrichtung umfasst zunächst eine Fördereinrichtung mit daran befestigten Zellen zur Aufnahme der Verpackungen. Durch eine Gable surfaces of packaging with sloping gable, in particular with continuous sloping gable. In particular, the fin seam and the ears in the gable area of the packaging are (re-) formed. The packaging is preferably a food packaging made from a composite material. The composite material may comprise a plurality of thin layers of paper, cardboard, plastic or metal. The device initially comprises a conveyor with cells attached thereto for receiving the packages. By a
Fördereinrichtung (beispielsweise ein Transportriemen, ein Transportband oder eine Transportkette) können hohe Zugkräfte übertragen werden, die es erlauben, eine Vielzahl von Packungsmänteln in konstanten Abständen zueinander zu Conveyor (for example, a conveyor belt, a conveyor belt or a transport chain) high tensile forces can be transmitted, which allow a plurality of packing coats at constant intervals to each other
transportieren. Die Zellen dienen der Aufnahme der Packungsmäntel. Die transport. The cells serve to accommodate the packaging coats. The
Packungsmäntel können sowohl durch eine formschlüssige Verbindung als auch durch eine kraftschlüssige Verbindung in den Zellen gehalten werden. Die Packungsmäntel can be held both by a positive connection and by a non-positive connection in the cells. The
Fördereinrichtung ist vorzugsweise in einer horizontalen Ebene angeordnet. Die Vorrichtung umfasst zudem wenigstens einen Giebelfalter zum Falten einer Conveyor is preferably arranged in a horizontal plane. The device also comprises at least one gable folder for folding a
Flossennaht im Giebelbereich der Verpackungen. Vorzugsweise ist der Giebelfalter zentral oberhalb der Fördereinrichtung und der darauf transportierten Verpackungen angeordnet. Zudem umfasst die Vorrichtung wenigstens zwei Ohrenfalter zum Falten von Ohren im Giebelbereich der Verpackungen. Vorzugsweise sind die beiden Fin seam in the gable area of the packaging. Preferably, the gable folder centrally above the conveyor and the packages transported thereon. In addition, the device comprises at least two earflaps for folding ears in the gable area of the packages. Preferably, the two are
Ohrenfalter oberhalb der Fördereinrichtung und der darauf transportierten Moth above the conveyor and transported thereon
Verpackungen beidseitig neben dem Giebelfalter angeordnet. Packaging arranged on both sides next to the pediment.
Erfindungsgemäß ist vorgesehen, dass sowohl der Giebelfalter als auch die According to the invention, it is provided that both the gable folder and the
Ohrenfalter relativ zu der Fördereinrichtung und den damit transportierten Upright relative to the conveyor and thus transported
Verpackungen beweglich gelagert sind. Mit anderen Worten sollen der Giebelfalter und die Ohrenfalter drehbar, schwenkbar, verschiebbar oder auf andere Weise beweglich gelagert sein. Durch diese konstruktive Maßnahme ist es möglich, dass die für die Formung erforderliche Relativbewegung zwischen den Faltwerkzeugen (also dem Giebelfalter und den Ohrenfaltern) und der Verpackung durch eine Bewegung der Faltwerkzeuge und nicht durch eine Bewegung der Verpackung erreicht wird. Dies hat zur Folge, dass die Verpackung während der Formgebung nicht bewegt werden braucht, so dass die Fördereinrichtung stillstehen kann. Es ist daher ein intermittierender, taktweise Betrieb der Fördereinrichtung möglich. Die Formgebung bei stillstehender Verpackung hat den Vorteil einer besonders einfachen Befüllung der Verpackungen, da die Befülleinrichtung nicht mitbewegt werden braucht. Ein weiterer Vorteil liegt darin, dass durch beweglich gelagerte Faltwerkzeuge auch Verpackungen geformt werden können, bei denen nicht die Flossennaht, sondern die hintere Kante des Giebels die höchste Stelle der Verpackungen bilden. Die Faltwerkzeuge können neben dem Umlegen der Flossennaht und dem Anlegen der Ohren auch dazu genutzt werden, andere Bereiche des Giebels zu formen, beispielsweise die gekrümmte vordere Kante des Giebels. Packaging are movably mounted. In other words, the pediment and the ear-butterfly should be rotatable, pivotable, displaceable or otherwise movably mounted. By this constructive measure, it is possible that the required relative to the shaping relative movement between the folding tools (ie the gable and the ear folds) and the packaging is achieved by a movement of the folding tools and not by a movement of the packaging. This has the consequence that the packaging does not need to be moved during shaping, so that the conveyor can stand still. It is therefore an intermittent, intermittent operation of the conveyor possible. The design with stationary packaging has the advantage of a particularly simple filling of the packaging, since the filling does not need to be moved. Another advantage is that can be formed by movably mounted folding tools and packaging, where not the fin seal, but the rear edge of the gable form the highest point of the packaging. The folding tools can also be used to form other areas of the gable, such as the curved leading edge of the gable, in addition to flipping the fin seam and engaging the ears.
Nach einer Ausgestaltung der Vorrichtung ist vorgesehen, dass der Giebelfalter in einer Ebene beweglich gelagert ist, insbesondere in einer Ebene die durch die According to one embodiment of the device, it is provided that the gable folder is movably mounted in a plane, in particular in a plane through the
Transportrichtung und die Hochrichtung der Verpackungen gebildet wird. Der Giebelfalter soll also nicht lediglich linear verschoben werden können, sondern eine wenigstens zweidimensionale Beweglichkeit aufweisen. In der Bewegungsebene kann der Giebelfalter Translationsbewegungen, Rotationsbewegungen oder Kombinationen aus beidem ausführen (Überlagerung aus Translations- und Rotationsbewegungen). Vorzugsweise wird die Bewegungsebene des Giebelfalters durch die Transport direction and the direction of the packaging is formed. Thus, the gable-hair folder should not be able to be displaced linearly, but should have an at least two-dimensional mobility. In the movement plane can the giebelfalter perform translation movements, rotational movements or combinations of both (superimposition of translational and rotational movements). Preferably, the plane of movement of the pediment by the age
Transportrichtung und die Hochrichtung der Verpackungen gebildet. Transport direction and the direction of the packaging formed.
Eine weitere Ausgestaltung der Vorrichtung sieht vor, dass die Ohrenfalter in einer Ebene beweglich gelagert sind, insbesondere in einer Ebene die durch die Another embodiment of the device provides that the ear moths are movably mounted in a plane, in particular in a plane through the
Hochrichtung und die Querrichtung der Verpackungen gebildet wird. Auch die Ohrenfalter sollen nicht lediglich linear verschoben werden können, sondern eine wenigstens zweidimensionale Beweglichkeit aufweisen. In der Bewegungsebene können die Ohrenfalter Translationsbewegungen, Rotationsbewegungen oder Kombinationen aus beidem ausführen (Überlagerung aus Translations- und High direction and the transverse direction of the packaging is formed. The moths should not be able to be moved linearly, but have an at least two-dimensional mobility. In the plane of movement, the earflaps can perform translational movements, rotational movements, or combinations of both (superposition of translation and translation)
Rotationsbewegungen). Vorzugsweise wird die Bewegungsebene der Ohrenfalter durch die Hochrichtung und die Querrichtung der Verpackungen gebildet. Rotational movements). Preferably, the plane of movement of the earflaps is formed by the vertical direction and the transverse direction of the packages.
Nach einer Weiterbildung der Vorrichtung wird vorgeschlagen, dass der Giebelfalter zwischen den beiden Ohrenfaltern angeordnet ist. Vorzugsweise sind der Giebelfalter und die Ohrenfalter oberhalb der Fördereinrichtung und der darauf transportierten Verpackungen angeordnet. Indem der Giebelfalter zwischen den beiden Ohrenfaltern angeordnet ist, wird eine besonders kompakte Bauweise erreicht. Dies ist besonders vorteilhaft bei Anlagen, in denen mehrere parallele Reihen von Verpackungen gleichzeitig bearbeitet werden. Zudem hat sich bei Versuchen herausgestellt, dass der Giebelfalter die Flossennaht auch dann zuverlässig umlegen kann, wenn er nicht die gesamte Breite der Flossennaht abdeckt, sondern etwa die Breite der Verpackung (ohne abstehende Ohren) abdeckt. According to a development of the device, it is proposed that the gable folder is arranged between the two ear folds. Preferably, the gable folder and the ear folders are arranged above the conveyor and the packages transported thereon. By arranging the gable folder between the two ear folds, a particularly compact design is achieved. This is particularly advantageous in installations where multiple parallel rows of packages are processed simultaneously. In addition, it has been found in experiments that the gable can reliably transfer the fin seam even if it does not cover the entire width of the fin seam, but about the width of the packaging (without protruding ears) covers.
Im Hinblick auf den Giebelfalter ist bei einer weiteren Ausgestaltung der Vorrichtung vorgesehen, dass der Giebelfalter derart beweglich gelagert ist, dass er die With regard to the gable folder is provided in a further embodiment of the device that the gable folder is mounted so movable that he
Flossennaht im Giebelbereich der Verpackungen in Richtung der Transportrichtung der Verpackungen umlegen kann. Dies soll auch dann möglich sein, wenn die schrägen Giebel der Verpackungen in Richtung der Transportrichtung ansteigen; die Flossennaht soll also„nach oben" umgelegt werden. Dies wird konstruktiv dadurch erreicht, dass der Giebelfalter nicht allein in vertikaler Richtung beweglich ist, sondern auch in Richtung der Transportrichtung der Verpackungen beweglich gelagert ist. Die Bewegungsrichtung des Giebelfalters soll also (jedenfalls auch) eine Bewegungskomponente in Richtung der Transportrichtung der Verpackungen aufweisen, um die Flossennaht in diese Richtung umlegen zu können. Floss seam in the gable area of the packaging can move in the direction of the transport direction of the packaging. This should also be possible if the sloping gables of the packaging increase in the direction of transport; the This is achieved constructively in that the gable folder is not only movable in the vertical direction, but is also movably mounted in the direction of transport of the packages Movement component in the direction of the transport direction of the packaging have to be able to move the fin seam in this direction.
Eine weitere Ausgestaltung der Vorrichtung ist gekennzeichnet durch wenigstens zwei, insbesondere wenigstens vier Giebelfalter zum Falten einer Flossennaht im Giebelbereich der Verpackungen, und wenigstens vier, insbesondere wenigstens acht Ohrenfalter zum Falten von Ohren im Giebelbereich der Verpackungen, wobei jeweils ein Giebelfalter und zwei Ohrenfalter eine Einheit zur Bearbeitung einer Verpackung bilden. Durch diese Ausgestaltung wird erreicht, dass mehrere Verpackungen gleichzeitig bearbeitet werden können. Hierzu können beispielsweise mehrere parallel verlaufende Transportbänder vorgesehen sein. Vorzugsweise ist jeder Reihe von zu bearbeitenden Verpackungen eine Einheit aus einem Giebelfalter und zwei Ohrenfaltern zugeordnet. Unter einer Einheit wird eine Gruppe von Faltwerkzeugen verstanden, die derart angeordnet sind, dass sie dieselbe Verpackung bearbeiten können. A further embodiment of the device is characterized by at least two, in particular at least four gable folders for folding a fin seam in the gable area of the packages, and at least four, in particular at least eight, ear folds for folding ears in the gable area of the packages, wherein one gable folder and two ear folders each form a unit to form a packaging. By this configuration it is achieved that a plurality of packages can be processed simultaneously. For this purpose, for example, a plurality of parallel conveyor belts may be provided. Preferably, each row of packages to be processed is associated with a gable-folder and two ear-trap unit. By a unit is meant a group of folding tools arranged to handle the same package.
Zu dieser Ausgestaltung wird weiter vorgeschlagen, dass alle Giebelfalter To this embodiment is further proposed that all gables
nebeneinander angeordnet sind und miteinander verbunden sind, und dass alle Ohrenfalter nebeneinander angeordnet sind und miteinander verbunden sind. Alle Giebelfalter sollen also miteinander verbunden sein, beispielsweise durch eine gemeinsame Schiene, an der alle Giebelfalter befestigt sind. Ebenso sollen alle are arranged side by side and connected to each other, and that all earflaps are arranged side by side and connected to each other. All gables should therefore be connected to each other, for example by a common rail, to which all gables are attached. Likewise, everyone should
Ohrenfalter miteinander verbunden sein; auch dies kann durch die Befestigung an einer gemeinsamen Schiene erfolgen. Die Verbindung der Giebelfalter hat den Vorteil, dass alle Giebelfalter durch einen gemeinsamen Antrieb synchron bewegt werden können. Ebenso können alle Ohrenfalter aufgrund ihrer Verbindung durch einen gemeinsamen Antrieb synchron bewegt werden. Die eingangs beschriebene Aufgabe wird auch gelöst durch ein Verfahren zum Formen der Giebelflächen von Verpackungen mit schrägem Giebel. Das Verfahren umfasst die folgenden Schritte: a) Bereitstellen von Verpackungen mit schrägen Giebeln, b) Falten der Flossennaht im Giebelbereich der Verpackungen durch einen Giebelfalter, und c) Falten der Ohren im Giebelbereich der Verpackungen durch zwei Ohrenfalter. Das Verfahren ist dadurch gekennzeichnet, dass bei den Schritten b) und c) sowohl der Giebelfalter als auch die Ohrenfalter relativ zu der Fördereinrichtung und den damit transportierten Verpackungen bewegt werden. Das Bereitstellen der Verpackungen kann insbesondere durch eine Fördereinrichtung in Gestalt eines Transportbandes oder eines Transportriemens oder einer Transportkette mit daran befestigten Zellen zur Aufnahme der Verpackungen erfolgen. Das Transportband bzw. der Earflaps be interconnected; This can also be done by attachment to a common rail. The connection of the gables has the advantage that all gables can be moved synchronously by a common drive. Likewise, all earflaps can be moved synchronously due to their connection by a common drive. The object described at the beginning is also achieved by a method for shaping the gable surfaces of packages with an inclined gable. The method comprises the following steps: a) providing packages with sloping gables, b) folding the fin seam in the gable area of the packages through a gable folder, and c) folding the ears in the gable area of the packages by two ear moths. The method is characterized in that in steps b) and c) both the gable folder and the ear folders are moved relative to the conveyor and the packages transported therewith. The provision of the packages can be carried out in particular by a conveyor in the form of a conveyor belt or a conveyor belt or a transport chain with cells attached thereto for receiving the packages. The conveyor belt or the
Transportriemen bzw. die Transportkette ist vorzugsweise in einer horizontalen Ebene angeordnet. Wie bereits im Zusammenhang mit der Vorrichtung beschrieben wurde, soll die für die Formung erforderliche Relativbewegung zwischen den Transport belt or the transport chain is preferably arranged in a horizontal plane. As already described in connection with the device, the required relative to the shaping relative movement between the
Faltwerkzeugen (also dem Giebelfalter und den Ohrenfaltern) und der Verpackung durch eine Bewegung der Faltwerkzeuge und nicht durch eine Bewegung der Folding tools (ie the gable and the earfolds) and the packaging by a movement of the folding tools and not by a movement of the
Verpackung erreicht werden. Dies hat zur Folge, dass die Verpackung während der Formgebung nicht bewegt werden braucht, was einen intermittierenden, taktweisen Betrieb der Fördereinrichtung ermöglicht. Die Formgebung bei stillstehender Packaging can be achieved. This has the consequence that the packaging does not need to be moved during the shaping, which enables an intermittent, cyclic operation of the conveyor. Shaping at rest
Verpackung hat den Vorteil, dass auch die Befüllung bei stillstehender Verpackung erfolgen kann und erlaubt zudem die Bearbeitung von Verpackungen, bei denen nicht die Flossennaht, sondern die hintere Kante des Giebels die höchste Stelle der Packaging has the advantage that the filling can be carried out at a standstill packaging and also allows the processing of packaging, where not the fin seam, but the rear edge of the pediment, the highest point of the
Verpackungen bilden. Vorzugsweise wird das Verfahren mit einer Vorrichtung nach einem der Ansprüche 1 bis 7 durchgeführt. Form packaging. Preferably, the method is carried out with a device according to one of claims 1 to 7.
Nach einer Ausgestaltung des Verfahrens ist vorgesehen, dass die Verpackungen durch eine Fördereinrichtung mit daran befestigten Zellen bewegt werden. Wie bereits zuvor im Zusammenhang mit der Vorrichtung beschrieben wurde, können durch eine Fördereinrichtung (beispielsweise ein Transportriemen, ein According to one embodiment of the method it is provided that the packages are moved by a conveyor with cells attached thereto. As has already been described in connection with the device, can by a conveyor (for example, a conveyor belt, a
Transportband oder eine Transportkette) hohe Zugkräfte übertragen werden, die es erlauben, eine Vielzahl von Packungsmänteln in konstanten Abständen zueinander zu transportieren. Die Zellen dienen der Aufnahme der Packungsmäntel. Die Conveyor belt or a transport chain) high tensile forces are transmitted, which allow a plurality of packing coats at constant intervals to each other transport. The cells serve to accommodate the packaging coats. The
Packungsmäntel können sowohl durch eine formschlüssige Verbindung als auch durch eine kraftschlüssige Verbindung in den Zellen gehalten werden. Die Packungsmäntel can be held both by a positive connection and by a non-positive connection in the cells. The
Fördereinrichtung ist vorzugsweise in einer horizontalen Ebene angeordnet. Conveyor is preferably arranged in a horizontal plane.
Gemäß einer Weiterbildung des Verfahrens ist vorgesehen, dass die Verpackungen intermittierend bewegt werden. Ein intermittierender, also taktweiser Betrieb hat den Vorteil, dass die Verpackungen kurzzeitig stillstehen und in dieser Phase präziser bearbeitet werden können. Ein weiterer Vorteil liegt darin, dass die Werkzeuge, welche die Verpackungen bearbeiten, nicht mit den Verpackungen mitbewegt werden brauchen. According to a development of the method, it is provided that the packages are moved intermittently. An intermittent, that is, tact-wise operation has the advantage that the packaging is temporarily stopped and can be processed more precisely in this phase. Another advantage is that the tools that handle the packages do not need to be moved along with the packages.
Eine weitere Ausgestaltung des Verfahrens sieht vor, dass die Verpackungen während Schritt b) und während Schritt c) stillstehen. Die Schritte b) und c) dienen dazu, die Flossennaht umzulegen und die abstehenden Ohren anzulegen. Diese Schritte sollen möglichst präzise und schnell durchgeführt werden, ohne die Verpackungen hierbei zu beschädigen oder zu deformieren. Diese Anforderungen lassen sich bei A further embodiment of the method provides that the packages stand still during step b) and during step c). The steps b) and c) are used to flip the fin seam and create the protruding ears. These steps should be carried out as precisely and quickly as possible without damaging or deforming the packaging. These requirements can be included
stillstehenden Verpackungen einfacher erfüllen als bei sich kontinuierlich stationary packaging easier than continuously
bewegenden Verpackungen. moving packaging.
Gemäß einer Weiterbildung des Verfahrens ist vorgesehen, dass Schritt b) vor Schritt c) ausgeführt wird. Alternativ oder zusätzlich ist vorgesehen, dass Schritt b) und Schritt c) sich zeitlich überschneiden. Vorzugsweise wird die Flossennaht umgelegt (Schritt b), bevor die Ohren an die Verpackung angelegt werden (Schritt c). Ein Vorteil dieser Schrittfolge liegt darin, dass die Ohren leichter angelegt werden können, wenn die Flossennaht bereits umgelegt ist. Dies liegt daran, dass sich die Flossennaht auch bis in den Bereich der Ohren erstreckt. Gleichwohl kann eine zeitliche According to a development of the method, provision is made for step b) to be carried out before step c). Alternatively or additionally, it is provided that step b) and step c) overlap in time. Preferably, the fin seam is folded over (step b) before the ears are applied to the package (step c). An advantage of this step sequence is that the ears can be applied more easily when the fin seam is already folded. This is because the fin seam also extends to the area of the ears. Nevertheless, a temporal
Überschneidung beider Schritte vorgesehen sein. Insbesondere kann mit dem Anlegen der Ohren bereits begonnen werden, bevor das Umlegen der Flossennaht vollständig beendet ist. Dies ermöglicht eine möglichst schnelle Giebelformung und somit kurze Taktzeiten. Nach einer weiteren Ausgestaltung des Verfahrens ist vorgesehen, dass der Intersection of both steps may be provided. In particular, the application of the ears can already be started before the folding of the fin seam is completely completed. This allows the fastest possible gable formation and thus short cycle times. According to a further embodiment of the method it is provided that the
Giebelfalter die Flossennaht im Giebelbereich der Verpackungen in Richtung der Transportrichtung der Verpackungen umlegt. Dies soll auch dann möglich sein, wenn die schrägen Giebel der Verpackungen in Richtung der Transportrichtung ansteigen; die Flossennaht soll also„nach oben" umgelegt werden. Ermöglicht wird dies dadurch, dass der Giebelfalter nicht allein in vertikaler Richtung bewegt wird, sondern auch in Richtung der Transportrichtung der Verpackungen bewegt wird. Die Giebelfalter folds the fin seam in the gable area of the packaging in the direction of the transport direction of the packaging. This should also be possible if the sloping gables of the packaging increase in the direction of transport; The fin seam should therefore be turned "upwards." This is made possible by the fact that the gable folder is not moved in the vertical direction alone but is also moved in the direction of the transport direction of the packaging
Bewegungsrichtung des Giebelfalters soll also (jedenfalls auch) eine Direction of movement of the gable-folding should therefore (at least also) one
Bewegungskomponente in Richtung der Transportrichtung der Verpackungen aufweisen, um die Flossennaht in diese Richtung umlegen zu können. Movement component in the direction of the transport direction of the packaging have to be able to move the fin seam in this direction.
Gemäß einer Weiterbildung des Verfahrens ist schließlich vorgesehen, dass die Giebelflächen von wenigstens zwei, insbesondere von wenigstens vier Verpackungen gleichzeitig geformt werden. Durch diese Weiterbildung wird erreicht, dass mehrere Verpackungen gleichzeitig bearbeitet werden können. Hierzu können beispielsweise mehrere parallel verlaufende Transportbänder vorgesehen sein. Vorzugsweise ist jeder Reihe von zu bearbeitenden Verpackungen eine Einheit aus einem Giebelfalter und zwei Ohrenfaltern zugeordnet. Unter einer Einheit wird eine Gruppe von According to a development of the method, it is finally provided that the gable surfaces of at least two, in particular of at least four packages are formed simultaneously. Through this development it is achieved that several packages can be processed simultaneously. For this purpose, for example, a plurality of parallel conveyor belts may be provided. Preferably, each row of packages to be processed is associated with a gable-folder and two ear-trap unit. Under a unit is a group of
Faltwerkzeugen verstanden, die derart angeordnet sind, dass sie dieselbe Verpackung bearbeiten können. Folding tools understood that are arranged so that they can handle the same packaging.

Fig. 1A zeigt einen Zuschnitt 1 zum Falten eines Packungsmantels. Der Zuschnitt 1 kann mehrere Lagen unterschiedlicher Materialien umfassen, beispielsweise Papier, Pappe, Kunststoff oder Metall, insbesondere Aluminium. Der Zuschnitt 1 weist mehrere Faltlinien 2 auf, die das Falten des Zuschnitts 1 erleichtern sollen und den Zuschnitt 1 in mehrere Flächen aufteilen. Der Zuschnitt 1 kann in eine Mantelfläche 3, Bodenflächen 4, Giebelflächen 5 und eine Siegelfläche 6 unterteilt werden. Die Bodenflächen 4 und die Giebelflächen 5 umfassen jeweils Rechtecksflächen 7, 7B, 7G und Dreiecksflächen 8. Die Giebelflächen 5 umfassen zudem eine zentral angeordnete Giebelhauptfläche 9. Die Mantelfläche 3 erstreckt sich - abgesehen von der Fig. 1A shows a blank 1 for folding a packing jacket. The blank 1 may comprise a plurality of 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 several areas. The blank 1 can be divided into a lateral surface 3, bottom surfaces 4, gable surfaces 5 and a sealing surface 6. The bottom surfaces 4 and the gable surfaces 5 each comprise rectangular surfaces 7, 7B, 7G and triangular surfaces 8. The gable surfaces 5 also comprise a centrally arranged gable main surface 9. The lateral surface 3 extends, with the exception of FIG
Siegelfläche 6 - über die gesamte Breite des Zuschnitts 1. Aus dem Zuschnitt 1 kann ein Packungsmantel gebildet werden, indem der Zuschnitt 1 derart gefaltet wird, dass die Siegelfläche 6 mit dem gegenüberliegenden Ende der Mantelfläche 3 verbunden, insbesondere verschweißt wird. Sealing surface 6 - over the entire width of the blank 1. From the blank 1, a packing jacket can be formed by the blank 1 is folded such that the sealing surface 6 is connected to the opposite end of the lateral surface 3, in particular welded.
Der in Fig. 1A gezeigte Zuschnitt 1 weist im Bereich der Mantelfläche 3 zwei The blank 1 shown in FIG. 1A has two in the area of the lateral surface 3
Scheinfaltlinien 10 auf. Die beiden Scheinfaltlinien 10 verlaufen parallel zueinander und verlaufen durch einen Berührungspunkt SB von drei benachbarten Fake fold lines 10 on. The two dummy fold lines 10 run parallel to one another and extend through a contact point SB of three adjacent ones
Dreiecksflächen 8 der Bodenfläche 4 und durch einen Berührungspunkt SG von drei benachbarten Dreiecksflächen 8 der Giebelflächen 5. Durch die Scheinfaltlinien 10 wird die Mantelfläche 3 in einen inneren Teilbereich 3A und in zwei äußere Triangular surfaces 8 of the bottom surface 4 and by a contact point SG of three adjacent triangular faces 8 of the gable surfaces 5. By the Scheinfaltlinien 10, the lateral surface 3 in an inner portion 3A and in two outer
Teilbereiche 3B geteilt. Der innere Teilbereich 3A liegt zwischen beiden Divisions 3B shared. The inner portion 3A lies between the two
Scheinfaltlinien 10 und die äußeren Teilbereiche 3B liegen außerhalb der beiden Scheinfaltlinien 10. Während die Bodenfläche 4 eine Länge L4 aufweist, die über die gesamte Breite des Zuschnitts 1 konstant ist, nimmt die Länge der Giebelfläche 5 unterschiedliche Werte ein. Angrenzend an die äußeren Teilbereiche 3B der Mantelfläche 3 weist die Apparent fold lines 10 and the outer portions 3B are outside the two dummy fold lines 10th While the bottom surface 4 has a length L4 which is constant over the entire width of the blank 1, the length of the gable surface 5 assumes different values. Adjacent to the outer portions 3 B of the lateral surface 3, the
Giebelfläche 5 eine verringerte Länge L5min auf. Angrenzend an den inneren Gable surface 5 a reduced length L5 m in on. Adjacent to the inner
Teilbereich 3A der Mantelfläche 3 (also im Bereich der Giebelhauptfläche 9) weist die Giebelfläche 5 hingegen eine vergrößerte Länge L5max auf. Diese Gestaltung führt dazu, dass der innere Teilbereich 3A eine geringere Höhe aufweist als die äußeren Partial area 3A of the lateral surface 3 (ie in the region of the main gable surface 9), the gable surface 5, however, an enlarged length L5 ma x on. This configuration results in that the inner portion 3A has a lower height than the outer portion
Teilbereiche 3B. Für die herzustellende Packung ergibt sich daraus ein geneigter, schräg nach vorn abfallender Giebelbereich. Subareas 3B. For the pack to be produced, this results in an inclined gable area sloping diagonally forward.
Die Rechtecksflächen 7B im Bodenbereich des Zuschnitts sind rechteckig. Die beiden äußeren Rechtecksflächen 7G im Giebelbereich des Zuschnitts sind ebenfalls rechteckig. Die mittlere Giebelhauptfläche 9 ist hingegen nicht exakt rechteckig; sie ist stattdessen mit einer wenigstens abschnittsweise konvex gebogenen Vorderkante 11 gebildet. In den oberen Eckbereichen der Giebelhauptfläche 9 erkennt man zwei gebogene Prägelinien 12, die der Giebelhaupfläche 9 eine an eine Ellipse erinnernde Gestaltung verleihen. Zentral innerhalb der Giebelhaupfläche 9 ist eine kreisförmige Schwächungslinie S gezeigt. Dabei handelt es sich bevorzugt um eine kreisrunde Aussparung im Trägermaterial, welche mit den übrigen Kunststoff- und ggf. Al- Schichten des Verbundmaterials überspannt ist, ein sog.„überbeschichtetes Loch". Dessen Durchmesser kann an die Größe des Schneidelements eines dort The rectangular areas 7B in the bottom area of the blank are rectangular. The two outer rectangular surfaces 7G in the gable area of the blank are also rectangular. The central gable main surface 9, however, is not exactly rectangular; Instead, it is formed with an at least partially convexly curved front edge 11. In the upper corner regions of the main gable surface 9, two curved embossed lines 12 are visible, which give the gable main surface 9 a design reminiscent of an ellipse. Centrally within the gable main surface 9 a circular weakening line S is shown. This is preferably a circular recess in the carrier material, which is covered with the remaining plastic and possibly Al layers of the composite material, a so-called "over-coated hole." Its diameter can correspond to the size of the cutting element of one there
anzubringenden Ausgießelementes angepasst sein oder relativ klein ausgeführt sein, um das Eindringen eines Trinkhalms zu ermöglichen. Die Bodenflächen 4 weisen zwei Eckpunkte E4 und die Giebelflächen 5 weisen zwei Eckpunkte E5 auf. Die Eckpunkte E4, E5 stellen Eckpunkte der aus dem Zuschnitt 1 herzustellenden Verpackung dar. Jedem Eckpunkt E4 einer Bodenfläche 4 ist ein entsprechender Eckpunkt E5 einer Giebelfläche 5 zugeordnet, bei dem es sich jeweils um denjenigen Eckpunkt E5 handelt, der bei stehender Verpackung oberhalb dieses Eckpunktes E4 angeordnet ist. Durch jeweils zwei korrespondierende Eckpunkte E4, E5 verläuft je eine Faltlinie 2', die jeweils zur Bildung einer hinteren (vertikal verlaufenden) Kante der herzustellenden Verpackung dient. Bei dem in Fig. 1A gezeigten Zuschnitt 1 sind jedoch - ebenso wie bei dem daraus hergestellten be adapted to be attached pouring or be made relatively small to allow the penetration of a drinking straw. The bottom surfaces 4 have two corner points E4 and the gable surfaces 5 have two corner points E5. The corner points E4, E5 represent corner points of the packaging to be produced from the blank 1. Each vertex E4 of a bottom surface 4 is assigned a corresponding vertex E5 of a gable surface 5, which in each case is that vertex E5 which, when the packaging is stationary, above this vertex E4 is arranged. By a respective two Corner vertices E4, E5 each have a fold line 2 ', each for forming a rear (vertical extending) edge of the packaging to be produced. In the blank 1 shown in Fig. 1A, however, as well as the one made therefrom
Packungsmantel und der daraus hergestellten Verpackung - nur zwei durchgehende Faltlinien 2' vorhanden. Zwischen den weiteren Eckpunkten der Bodenflächen 4 und den korrespondierenden Eckpunkten der Giebelflächen 5 - also auf der vorderen Mantelfläche 3A hingegen keine Faltlinien vorgesehen. Packing jacket and the packaging produced therefrom - only two continuous fold lines 2 'present. In contrast, no fold lines are provided between the further corner points of the bottom surfaces 4 and the corresponding corner points of the gable surfaces 5 - that is, on the front lateral surface 3A.
Fig. 1B zeigt einen Packungsmantel 13, der aus dem in Fig. 1A gezeigten Zuschnitt 1 gebildet ist, im flach gefalteten Zustand in einer Vorderansicht. Die bereits im Fig. 1B shows a packing jacket 13, which is formed from the blank 1 shown in Fig. 1A, in the flat folded state in a front view. The already in the
Zusammenhang mit Fig. 1A beschriebenen Bereiche des Packungsmantels sind in Fig. 1B mit entsprechenden Bezugszeichen versehen. Der Packungsmantel 13 ist durch zwei Schritte aus dem Zuschnitt 1 entstanden: Zunächst wird der Zuschnitt 1 entlang der beiden Scheinfaltlinien 10 gefaltet. Anschließend werden die beiden Teilbereiche 3B (links) und 3B (rechts) der Mantelfläche 3 im Bereich der Siegelfläche 6 Portions of the packing jacket described in connection with FIG. 1A are provided with corresponding reference symbols in FIG. 1B. The packing jacket 13 has been formed from the blank 1 by two steps. First, the blank 1 is folded along the two dummy fold lines 10. Subsequently, the two partial areas 3B (left) and 3B (right) of the lateral surface 3 in the area of the sealing surface 6
miteinander verbunden, insbesondere verschweißt, wodurch eine (in Fig. 1B verdeckte) Längsnaht 14 entsteht. Der Packungsmantel 1 hat also eine umlaufende, in Umfangsrichtung geschlossene Struktur mit einer Öffnung im Bereich der connected together, in particular welded, whereby a (in Fig. 1B hidden) longitudinal seam 14 is formed. The packing jacket 1 thus has a circumferential, circumferentially closed structure with an opening in the region of
Bodenflächen 4 und mit einer Öffnung im Bereich der Giebelflächen 5. In der Bottom surfaces 4 and with an opening in the area of the gable surfaces 5. In the
Vorderansicht ist der innere Teilbereich 3A der Mantelfläche 3 sichtbar, der beidseitig von den Scheinfaltlinien 10 begrenzt wird. Die übrigen Teilbereiche 3B der Front view, the inner portion 3A of the lateral surface 3 is visible, which is bounded on both sides by the dummy fold lines 10. The remaining sections 3B of
Mantelfläche 3 sind auf der Rückseite des Packungsmantels 13 und daher in Fig. 1B verdeckt. The lateral surface 3 are concealed on the rear side of the packing jacket 13 and therefore in FIG. 1B.
In Fig. IC ist der Packungsmantel 13 aus Fig. 1B in einer Rückansicht dargestellt. Die bereits im Zusammenhang mit Fig. 1A und Fig. 1B beschriebenen Bereiche desFIG. 1C shows the packaging jacket 13 from FIG. 1B in a rear view. The areas of the already described in connection with FIGS. 1A and 1B
Packungsmantels sind in Fig. IC mit entsprechenden Bezugszeichen versehen. In der Rückansicht sind die beiden äußeren Teilbereiche 3B der Mantelfläche 3 sichtbar, die durch die Längsnaht 14 miteinander verbunden sind und die beidseitig von den Scheinfaltlinien 10 begrenzt wird. Der vordere Teilbereich 3A der Mantelfläche 3 ist auf der Vorderseite des Packungsmantels 13 und daher in Fig. IC verdeckt. Fig. 1D zeigt den Packungsmantel 13 aus Fig. 1B und Fig. IC im aufgefalteten Zustand. Die bereits im Zusammenhang mit Fig. 1A bis Fig. IC beschriebenen Bereiche des Packungsmantels sind in Fig. 1D mit entsprechenden Bezugszeichen versehen. Der aufgefaltete Zustand wird durch eine Rückfaltung des Packungsmantels 13 entlang der durch die Mantelfläche 3 verlaufenden Scheinfaltlinien 10 erreicht. Die Packungsmantels are provided in Fig. IC with corresponding reference numerals. In the rear view, the two outer portions 3 B of the lateral surface 3 are visible, which are interconnected by the longitudinal seam 14 and which is bounded on both sides by the dummy fold lines 10. The front portion 3A of the lateral surface 3 is concealed on the front side of the package shell 13 and therefore in Fig. IC. Fig. 1D shows the packing jacket 13 of Fig. 1B and Fig. IC in the unfolded state. The regions of the packing jacket which have already been described in connection with FIGS. 1A to 1C are provided with corresponding reference symbols in FIG. 1D. The unfolded state is achieved by a folding back of the packing jacket 13 along the dummy fold lines 10 passing through the lateral surface 3. The
Rückfaltung erfolgt um etwa 180°. Die Rückfaltung entlang der Scheinfaltlinien 10 hat zur Folge, dass die beiden an die Scheinfaltlinie 10 angrenzenden Teilbereiche 3A, 3B der Mantelfläche 3 nicht mehr flach aufeinander liegen, sondern in derselben Ebene angeordnet sind. Der Packungsmantel 13 ist daher nur in seinem flachen Zustand (Fig. 1B, Fig. IC) entlang der Scheinfaltlinien 10 gefaltet; im aufgefalteten Zustand (Fig. 1D) ist der Packungsmantel 13 (ebenso wie die daraus herzustellende Verpackung) hingegen nicht mehr entlang der Scheinfaltlinien 10 gefaltet. Daher die Bezeichnung „Schein"-Faltlinien 10. In Fig. IE ist der Packungsmantel aus Fig. 1B bis Fig. 1D mit geschlossenem Boden dargestellt. Die bereits im Zusammenhang mit Fig. 1A bis Fig. 1D beschriebenen Bereiche des Packungsmantels sind in Fig. 1D mit entsprechenden Bezugszeichen versehen. Der Boden kann beispielsweise verschlossen werden, während der aufgefaltete Packungsmantel 13 auf einen Dorn eines Dornrades aufgeschoben ist. Zum Verschließen des Bodens werden beispielsweise zunächst die unteren Refolding occurs about 180 °. The refolding along the dummy fold lines 10 has the consequence that the two partial regions 3A, 3B of the lateral surface 3 adjoining the dummy fold line 10 no longer lie flat on one another, but are arranged in the same plane. The packing jacket 13 is therefore folded along the apparent fold lines 10 only in its flat state (FIG. 1B, FIG. 1C); In the unfolded state (FIG. 1D), the packing jacket 13 (as well as the packaging to be produced therefrom) is no longer folded along the apparent fold lines 10. Therefore, the term "sham" fold lines 10. In Fig. IE, the packing sheath of Fig. 1B to Fig. 1D is shown with closed bottom. The areas of the packing sheath already described in connection with Fig. 1A to Fig. 1D are shown in FIG. For example, the bottom may be closed while the unfolded packing jacket 13 is pushed onto a mandrel of a mandrel wheel
Dreiecksflächen 8 nach innen gefaltet, bevor die unteren Rechtecksflächen 7B nach innen gefaltet werden. Die zusammengefalteten Flächen werden anschließend durch Einwirkung von Druck und Temperatur verschweißt. Fig. 1F zeigt den Packungsmantel aus Fig. 1B bis Fig. IE mit vorgefalteten Triangular surfaces 8 folded inwards before the lower rectangular surfaces 7B are folded inwards. The folded surfaces are then welded by the action of pressure and temperature. FIG. 1F shows the packing jacket from FIGS. 1B to IE with pre-folded. FIG
Giebelflächen. Die bereits im Zusammenhang mit Fig. 1A bis Fig. IE beschriebenen Bereiche des Packungsmantels sind in Fig. 1F mit entsprechenden Bezugszeichen versehen. Der vorgefalteten Zustand bezeichnet einen Zustand, in dem die Faltlinien 2 im Bereich der Giebelflächen 5 vorgefaltet worden sind. Die Rechtecksfläche 7G und die Giebelhauptfläche 9 werden bei der Vorfaltung nach innen gefaltet und bilden später den Giebel der Verpackung. Die Dreiecksflächen 8 werden bei der Vorfaltung hingegen nach außen gefaltet und bilden abstehende Bereiche aus überschüssigem Material, die auch als„Ohren" 15 bezeichnet werden und in einem späteren Gables. The regions of the packing jacket already described in connection with FIGS. 1A to IE are provided with corresponding reference symbols in FIG. 1F. The pre-folded state denotes a state in which the fold lines 2 have been prefolded in the region of the gable surfaces 5. The rectangular area 7G and the main gable surface 9 are folded inward during the prefolding and later form the gable of the packaging. The triangular faces 8 are at the pre-fold on the other hand folded outwards and form protruding areas of excess material, which are also referred to as "ears" 15 and in a later
Herstellungsschritt - etwa durch Klebverfahren - an die Mantelfläche 3 der Manufacturing step - for example by gluing - to the lateral surface 3 of the
Verpackung angelegt werden. Packaging to be created.
Fig. IG zeigt eine Verpackung 16, die aus dem in Fig. 1B bis Fig. 1F gezeigten Fig. IG shows a package 16 which is shown in Fig. 1B to Fig. 1F
Packungsmantel 13 hergestellt ist, mit ungeformtem Giebel. Die bereits im Packing jacket 13 is made, with unformed gable. The already in the
Zusammenhang mit Fig. 1A bis Fig. 1F beschriebenen Bereiche der Verpackung sind in Fig. IG mit entsprechenden Bezugszeichen versehen. Die Verpackung 16 ist nach dem Verschweißen, also im befüllten und verschlossenen Zustand gezeigt. Aufgrund der vergrößerten Länge L5max der Giebelhauptfläche 9 in ihrem an den inneren Teilbereich 3A der Mantelfläche 3 angrenzenden Bereich sowie der verringerten Länge L5min der Giebelfläche 5 in ihrem an die äußeren Teilbereiche 3B der In connection with FIG. 1A to FIG. 1F described areas of the packaging are provided in Fig. IG with corresponding reference numerals. The packaging 16 is shown after welding, ie in the filled and closed state. Due to the increased length L5 ma x of the main gable surface 9 in its adjacent to the inner portion 3A of the lateral surface 3 region and the reduced length L5 m in the gable surface 5 in their to the outer portions 3B of
Mantelfläche 3 angrenzenden Bereich entsteht eine vergrößerte Giebelhauptfläche 9. Auf dieser Giebelhauptfläche 9 kann die Verpackung 16 mit einem Ausgießelement versehen werden, welches fast bis zur nach vorne gewölbten Vorderkante 11 heranreicht. Im Bereich der Giebelflächen 5 entsteht nach dem Verschließen eine Flossennaht 17. In Fig. IG stehen die Ohren 15 und die Flossennaht 17 ab. Die Ohren 15 werden in einem späteren Herstellungsschritt, etwa durch Klebverfahren, angelegt, wodurch auch die Flossennaht 17 automatisch in einer flachen Stellung verbleibt. On this gable main surface 9, the package 16 may be provided with a pouring element which extends almost to the forward curved leading edge 11. In the area of the gable surfaces 5, a fin seam 17 is produced after closure. In FIG. 1G, the ears 15 and the fin seam 17 are protruded. The ears 15 are applied in a later manufacturing step, such as by adhesive bonding, whereby the fin seam 17 automatically remains in a flat position.
In Fig. 1H ist die Verpackung 16 aus Fig. IG mit geformtem Giebel, insbesondere mit angelegten Ohren 15 dargestellt. Die bereits im Zusammenhang mit Fig. 1A bis Fig. 2G beschriebenen Bereiche der Verpackung sind in Fig. 1H mit entsprechenden In Fig. 1H, the package 16 of FIG. IG with a shaped pediment, in particular with applied ears 15 is shown. The areas of the packaging already described in connection with FIGS. 1A to 2G are shown in FIG. 1H with corresponding ones
Bezugszeichen versehen. Neben den Ohren 15 ist auch die Flossennaht 17 an die Verpackung 16 angelegt. Die oberen, im Bereich der Giebelfläche 5 angeordneten Ohren 15 sind nach unten umgeklappt und flach an die Mantelfläche 3 angelegt. Provided with reference numerals. In addition to the ears 15, the fin seam 17 is also applied to the packaging 16. The upper, arranged in the region of the gable surface 5 ears 15 are folded down and placed flat against the lateral surface 3.
Vorzugsweise sind die Ohren 15 mit der Mantelfläche 3 verklebt oder verschweißt. Die in Fig. 1H dargestellte Verpackung 16 weist im Bereich der vorderen Mantelfläche 3A keine Faltkanten auf. Die nach vorne gewölbte Vorderseite der Verpackung lässt sich im rechts dargestellten Horizontalschnitt durch die Ebene E der Verpackung deutlich erkennen. Die geraden Faltlinien 2' an den hinteren Packungskanten verlaufen von den unteren Eckpunkten E4 bis zu den oberen Eckpunkten E5. Preferably, the ears 15 are glued or welded to the lateral surface 3. The packaging 16 shown in FIG. 1H has no folded edges in the area of the front lateral surface 3A. The forwardly curved front of the packaging can be in the horizontal section shown on the right by the plane E of the packaging clearly recognize. The straight fold lines 2 'at the rear packing edges extend from the lower corner points E4 to the upper corners E5.
Fig. 2 zeigt eine Anlage 18 zum Befüllen und Verschließen von Verpackungen in einer Seitenansicht. Die Anlage 18 umfasst eine umlaufende Fördereinrichtung 19 mit daran befestigten Zellen 20 zur Aufnahme von Packungsmänteln 13. Die Packungsmäntel 13 werden in dem in Fig. IE dargestellten Zustand, also mit bereits verschlossenen Bodenflächen, in die Zellen 20 eingeschoben. Die Anlage 18 umfasst eine Vorrichtung 21 zur Vorfaltung der Giebelflächen, eine Vorrichtung 22 zum Befüllen der Fig. 2 shows a system 18 for filling and closing of packages in a side view. The system 18 comprises a circulating conveyor 19 with cells 20 attached thereto for receiving packaging sheaths 13. The packaging shells 13 are inserted into the cells 20 in the state shown in FIG. 1 IE, that is to say with already closed bottom surfaces. The system 18 comprises a device 21 for prefolding the gable surfaces, a device 22 for filling the gable surfaces
Packungsmäntel, eine Vorrichtung 23 zum Verschließen der Packungsmäntel und eine Vorrichtung 24 zum Formen der Giebel der Verpackungen 16. In der Vorrichtung 21 zur Vorfaltung der Giebelflächen werden die Giebelflächen in der bereits zuvor beschriebenen Weise vorgefaltet, wobei die Packungsmäntel 13 die in Fig. 1F gezeigte Form einnehmen. In der Vorrichtung 22 zum Befüllen der Packungsmäntel werden die Packungsmäntel 13 mit Inhalten befüllt. Anschließend werden die Packungsmäntel 13 in der Vorrichtung 23 zum Verschließen der Packungsmäntel verschlossen, wobei sie die in Fig. IG gezeigte Form einnehmen. Nach dem Verschließen werden die Packing shells, a device 23 for closing the packaging shells and a device 24 for forming the gables of the packages 16. In the gable surface folding device 21, the gable surfaces are prefolded in the manner already described, the packing shells 13 being those shown in Fig. 1F Take shape. In the apparatus 22 for filling the packaging coats, the packaging coats 13 are filled with contents. Subsequently, the packing shells 13 are closed in the device 23 for closing the packing shells, taking the shape shown in Fig. IG. After closing, the
Packungsmäntel 13 als Verpackungen 16 bezeichnet. Danach werden die Packungsmäntel 13 referred to as packaging 16. After that, the
Verpackungen 16 in der Vorrichtung 24 zum Formen der Giebel der Verpackungen derart bearbeitet, dass sie die in Fig. 1H gezeigte Form einnehmen. Die Bearbeitung umfasst ein Umlegen der Flossennaht 17 sowie ein Anlegen der Ohren 15. Im Packages 16 are processed in the device 24 for forming the gables of the packaging so that they assume the shape shown in Fig. 1H. The processing includes a folding of the fin seam 17 and an application of the ears 15. Im
Anschluss daran werden die Verpackungen 16 aus den Zellen 20 der Following this, the packaging 16 from the cells 20 of
Fördereinrichtung 19 entnommen. In Fig. 3A ist eine erfindungsgemäße Vorrichtung 24 zum Formen der Giebelflächen von Verpackungen mit schrägem Giebel in einer offenen Stellung in Seitenansicht gezeigt. Fig. 3B zeigt die Vorrichtung 24 aus Fig. 3A in einer Vorderansicht. Die Vorrichtung 24 umfasst drei Faltwerkzeuge: einen zentral angeordneten Giebelfalter 25 und zwei daneben angeordnete Ohrenfalter 26A, 26B. Der Giebelfalter 25 ist beweglich gelagert und dient dazu, die Flossennaht 17 umzulegen. Die beiden Conveyor 19 taken. Referring now to Fig. 3A, there is shown a side view of an apparatus 24 for forming the gable surfaces of oblique gable packages in an open position. Fig. 3B shows the device 24 of Fig. 3A in a front view. The device 24 comprises three folding tools: a centrally located gable folder 25 and two adjacent moth flaps 26A, 26B. The gable folder 25 is movably mounted and serves to flip the fin seam 17. The two
Ohrenfalter 26A, 26B sind ebenfalls beweglich gelagert und dienen dazu, die beiden Ohren 15 umzulegen. Die bewegliche Lagerung des Giebelfalters 25 hat den Vorteil, dass die Flossennaht 17 gut erreicht werden kann, obgleich sie niedriger angeordnet sein kann als die höchste Kante der Verpackung 16. Der Giebelfalter 25 ist derart gelagert, dass er in einer Ebene bewegt werden kann, die durch die der Earsheets 26A, 26B are also movably mounted and serve the two Turn down ears 15. The moveable support of the gable retardant 25 has the advantage that the fin seam 17 can be easily reached, although it may be located lower than the highest edge of the package 16.
