Description

Die Erfindung bezieht sich auf eine Vorrichtung zum Herstellen einer Polsterpackung aus einer oder mehreren Papierlagen mit einer zusammengefalteten Decklage, die wenigstens eine Zwischenlage umhüllen kann, wobei die Polsterpackung an wenigstens einem ihrer Längsränder mit nach innen gerichteten Einprägungen versehen ist, wobei die Papierlagen in ihrer Längsrichtung durch die Maschinenlängsrichtung laufen, wobei eine Formeinrichtung vorgesehen ist, in welcher wenigstens ein Verformwerkzeug angeordnet ist, das an einem Seitenrand der Decklage angreift und in Höhenrichtung der Vorrichtung schräg angeordneten Verformfinger aufweist, der eine Stauchung auszuführen vermag.The invention relates to an apparatus for producing a cushioning pack from one or more paper layers with a folded cover layer, which can wrap at least one intermediate layer, wherein the padding package is provided on at least one of its longitudinal edges with inwardly directed embossments, wherein the paper layers in their longitudinal direction run through the machine longitudinal direction, wherein a shaping device is provided, in which at least one deformation tool is arranged, which acts on a side edge of the cover layer and in the height direction of the device has obliquely arranged Verformfinger that is capable of performing a compression.

Zum Verformen derartiger Polsterpackungen werden meist Zahnräder eingesetzt, die gleichzeitig die Verformung und den Vorschub während des Verfomungsvorganges bewirken.To deform such cushioning packages usually gears are used, which simultaneously cause the deformation and the feed during Verfomungsvorganges.

Dabei besteht jedoch die Gefahr, dass zumindest die äußere Papierlage eingerissen wird.However, there is a risk that at least the outer paper layer is torn.

Aus der EP 1 497 049 A2 ist beispielsweise eine solche Vorrichtung bekannt, bei der gleichmäßig gerippte, zahnradartige Räder zum Stauchen der Papierlagen vorgesehen sind.From the EP 1 497 049 A2 For example, such a device is known, are provided in the evenly ribbed, gear-like wheels for upsetting the paper layers.

Aus der DE 196 24 164 A1 ist eine weitere Vorrichtung zum Herstellen von Polsterpackungen bekannt, welche anstelle von Zahnrädern mit Verformfingern arbeitet.From the DE 196 24 164 A1 Another device for producing upholstery packings is known, which works instead of gears with Verformfingern.

Hiervon ausgehend liegt der Erfindung die Aufgabe zugrunde, eine Polsterpackung vorzuschlagen, die weitgehend materialschonend hergestellt wird und damit keine Einrisse aufweist.Proceeding from this, the object of the invention is to propose a cushioning pack which is manufactured in a manner that is gentle on the material and thus has no tears.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die der Decklage zugewandte Fläche des Verformwerkzeuges stetig schräg ausgebildet ist.This object is achieved in that the cover layer facing surface of the forming tool is formed continuously sloping.

Dadurch sind die getrennt vom Vorschub erzeugten Querstauchungen, in ihrer Höhe unterschiedlich, wodurch eine sehr effektive Verformung erhalten wird und Papierbeschädigungen nicht zu befürchten sind.As a result, the transverse buckling generated separately from the feed, differing in height, whereby a very effective deformation is obtained and paper damage is not to be feared.

Darüber hinaus wird im Bereich der Stauchungen eine Verdrehung der Polsterpackung um die Längsachse erzeugt. Dadurch wird die Polsterpackung in einer sehr voluminösen Form hergestellt, was sich als sehr vorteilhaft erwiesen hat.In addition, in the area of the upsets, a twisting of the cushioning pack about the longitudinal axis is generated. As a result, the cushioning pack is produced in a very voluminous shape, which has proven to be very advantageous.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß zwei Verformwerkzeuge vorgesehen sind, die synchron zueinander angetrieben sind und die Polsterpackung zwischen sich einspannen und verformen.A further advantageous embodiment of the invention is characterized in that two Verformwerkzeuge are provided which are driven synchronously to each other and clamp the cushion pack between them and deform.

Hierdurch bleibt die Polsterpackung auch beim Einbringen der Querstauchungen weitgehend formstabil und die Polsterpackung muss beim Verformen nicht zusätzlich unterstützt werden.As a result, the cushioning pack remains largely dimensionally stable even when introducing the transverse compressions and the cushioning pack does not need to be additionally supported during deformation.

Sehr vorteilhaft ist es auch, wenn erfindungsgemäß die Verformfinger der Verformwerkzeuge wenigstens annähernd parallel zueinander ausgerichtet sind.It is also very advantageous if, according to the invention, the deforming fingers of the deforming tools are aligned at least approximately parallel to one another.

Diese bewirkt, dass die Verformkräfte ausschliesslich auf die Polsterpackung wirken.This causes the deformation forces to act exclusively on the cushioning pack.

Gemäß einer weiteren vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, daß die Verformwerkzeuge drehbar gelagert und gegenläufig angetrieben sind, und daß die Verformwerkzeuge jeweils wenigstens einen Verformarm aufweisen, an dem wenigstens ein Verformfinger vorgesehen ist.According to a further advantageous embodiment of the invention it is provided that the deformation tools are rotatably mounted and driven in opposite directions, and that the deformation tools each have at least one Verformarm on which at least one Verformfinger is provided.

Dabei hat es sich als besonders vorteilhaft erwiesen, wenn gemäß einer weiteren Ausgestaltung der Erfindung jedes Verformwerkzeug zwei einander diametral gegenüberliegende Verformarme aufweist.It has proved to be particularly advantageous if, according to a further embodiment of the invention, each forming tool has two diametrically opposed deformation arms.

Erfindungsgemäß ist es dabei möglich, daß jeder Verformarm an seinem freien Ende wenigstens zwei Verformfinger aufweist.According to the invention it is possible that each Verformarm has at least two Verformfinger at its free end.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, dass hinter den Verformwerkzeugen eine Abschneidvorrichtung angeordnet ist.A further advantageous embodiment of the invention is that behind the Verformwerkzeugen a cutting device is arranged.

Damit kann dann die Polsterpackung unmittelbar auf die vorgesehene Länge abgeschnitten werden.Thus, the cushioning pack can then be cut directly to the intended length.

Erfindungsgemäß kann die Abschneidvorrichtung am Ende der Formeinrichtung angeordnet sein.According to the invention, the cutting device can be arranged at the end of the molding device.

Bei einer vorteilhaften Ausgestaltung der Erfindung ist vorgesehen, dass die Abschneidvorrichtung ein hin und her bewegtes Schneidmesser aufweist, das gegen ein am Ende der Formeinrichtung angeordnetes Gegenwerkzeug arbeitet.In an advantageous embodiment of the invention it is provided that the cutting device has a reciprocating cutting blade which operates against a arranged at the end of the mold counter-tool.

Das Schneidmesser kann gemäß einer weiteren Ausgestaltung der Erfindung um einen Drehpunkt drehbar gelagert sein.The cutting blade can be rotatably mounted about a pivot point according to a further embodiment of the invention.

Darüber hinaus ist es möglich, daß das Schneidmesser mit der Schwerkraft wirkend ausgebildet ist.In addition, it is possible that the cutting blade is designed to act with gravity.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß in Bewegungsrichtung der Lage bzw. der Polsterpackung vor den Verformwerkzeugen eine intermittierend arbeitende Vorschubeinrichtung für die noch flachliegende Lage vorgesehen ist, deren Transportgeschwindigkeit höher ist als die der Verformwerkzeuge.A further advantageous embodiment of the invention is characterized in that an intermittently operating feed device is provided for the still flat lying position in the direction of movement of the layer or the cushioning pack before the Verformwerkzeugen whose transport speed is higher than that of the forming tools.

Dadurch wird bereits vor dem dem Verformen in Querrichtung eine Stauchung in Längsrichtung erzielt, so dass beim Querverformen keine Materialschädigung eintritt.As a result, a compression in the longitudinal direction is achieved even before the deformation in the transverse direction, so that no material damage occurs during transverse deformation.

Eine ebenfalls sehr vorteilhafte Ausgestaltung der Erfindung liegt darin, dass eine Falteinrichtung vorgesehen ist, in welcher eine Decklage der Polsterpackung so zusammengefaltet wird, daß sich eine wenigstens weitgehend geschlossene Hülle bildet.Another very advantageous embodiment of the invention is that a folding device is provided, in which a cover layer of the cushioning pack is folded so that forms an at least substantially closed shell.

Als sehr vorteilhaft hat es sich auch erwiesen, wenn gemäß einer weiteren Ausgestaltung der Erfindung eine Zuführvorrichtung vorgesehen ist, mit welcher wenigstens eine Zwischenlage in die Hülle eingebracht wird.It has also proven to be very advantageous if, according to a further embodiment of the invention, a feeding device is provided with which at least one intermediate layer is introduced into the casing.

Gemäß einer weiteren Ausgestaltung der Erfindung ist eine Klebeeinrichtung vorgesehen, in welcher die beiden Längsränder der Decklage miteinander bzw. mit der benachbarten Zwischenlage verklebt werden.According to a further embodiment of the invention, an adhesive device is provided, in which the two longitudinal edges of the cover layer are glued together or with the adjacent intermediate layer.

In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispiels veranschaulicht. Dabei zeigen:

  • Fig.2 eine schaubildliche Darstellung einer fertig verformten Polsterpackung,
  • Fig.3 eine schematische Darstellung einer Vorrichtung zum Herstellen der Polsterpackung nach Fig.2 in Draufsicht
  • Fig.4 eine schematische Darstellung der Vorrichtung nach Fig.3 im Querschnitt und

In the drawing, the invention is illustrated by means of an embodiment. Showing:
  • Fig.1 a section through a folded, still flat lying position,
  • Fig.2 a perspective view of a fully formed upholstery pack,
  • Figure 3 a schematic representation of an apparatus for producing the cushioning pack according to Fig.2 in plan view
  • Figure 4 a schematic representation of the device according to Figure 3 in cross-section and
  • Figure 5 a schematic side view of the device according to Figure 3 ,

Mit 1 ist in Fig.1 eine flachliegende Papierlage bezeichnet, die aus einer Decklage 2 und zwei Zwischenlagen 3 und 4 besteht. Die Decklage 2 ist um die beiden Zwischenlagen 3 und 4 herumgefaltet, wobei die beiden Randstreifen 5 und 6 der Decklage auf der Oberseite der Papierlage 1 angeordnet sind und einander überlappen.With 1 is in Fig.1 denotes a flat lying paper layer, which consists of a cover layer 2 and two intermediate layers 3 and 4. The cover layer 2 is folded around the two intermediate layers 3 and 4, wherein the two edge strips 5 and 6 of the cover layer are arranged on the upper side of the paper layer 1 and overlap each other.

Dabei können die beiden Randstreifen lose aufeinander liegen oder miteinander verklebt sein.In this case, the two edge strips may be loose or glued together.

Auch ist es möglich die beiden Randstreifen nur aneinander stoßen oder mit einem Abstand voneinander enden zu lassen.It is also possible the two edge strips only abut each other or end with a distance from each other.

Wird eine höhere Festigkeit gewünscht, so können die beiden Randstreifen untereinander bzw. mit der benachbarten Zwischenlage verklebt werden.If a higher strength is desired, the two edge strips can be glued together or with the adjacent intermediate layer.

Anstelle von Papier ist sowohl für die Decklage 2 als auch für die Zwischenlage jedes andere flächige Material wie z.B. Folie oder Vlies oder auch Karton einsetzbar.Instead of paper, for the cover layer 2 as well as for the intermediate layer any other sheet material such as e.g. Foil or fleece or cardboard can be used.

Je nach Anforderung ist es möglich nur eine Zwischenlage oder auch mehrere vorzusehen; darüber hinaus kann auch ganz ohne Zwischenlagen gearbeitet werden.Depending on the requirement, it is possible to provide only one intermediate layer or several; In addition, you can work without any intermediate layers.

Diese Papierlage 1 kann nach ihrer Herstellung aufgerollt und einer getrennten Umformstation oder auch unmittelbar einer Formeinrichtung zugeführt werden. Dabei wird dann eine Polsterpackung 7 geschaffen, welche etwa die in Fig.2 dargestellte Form aufweist und zum Abpolstern von Transportverpackungen sehr gut geeignet ist.This paper layer 1 can be rolled up after its production and fed to a separate forming station or also directly to a forming device. In this case, a cushion pack 7 is then created, which approximately in Fig.2 has shown shape and is very well suited for padding of transport packaging.

In Fig.3 ist eine Vorrichtung zum Umformen der Papierlage 1 in eine Polsterpackung 7 dargestellt. Dazu sind zwei gegenläufig angetriebene Verformwerkzeuge 10 und 11 vorgesehen, die über ein nicht dargestelltes Zahnradpaar synchronisiert sind. Die beiden Verformwerkzeuge 10,11 sind zweiarmig ausgebildet und weisen beide entweder einen Finger (nicht dargestellt), zwei Finger 13, wie dies beim Verformwerkzeug 10 dargestellt ist oder drei Finger 14, wie dies anhand des Verformwerkzeuges 11 gezeigt ist, auf.In Figure 3 a device for forming the paper layer 1 is shown in a cushioning pack 7. For this purpose, two counter-rotating deformation tools 10 and 11 are provided, which are synchronized via a gear pair, not shown. The two forming tools 10,11 are formed with two arms and both have either a finger (not shown), two fingers 13, as shown in the forming tool 10 or three fingers 14, as shown by the forming tool 11, on.

Wie Fig.4 ist die der Papierlage 1 bzw. der Polsterlage 7 zugewandte Fläche der Verformwerkzeuge 10,11 schräg ausgebildet. Dabei sind die beiden Verformwerkzeuge gleich angeordnet, so dass die beiden Arme bzw. Finger 13,14 der Verformwerkzeuge abwechsend oben und unten an der Papierlage 1 bzw. der Polsterlage 7 angreifen.As Figure 4 is the paper layer 1 and the cushion layer 7 facing surface of the forming tools 10,11 formed obliquely. In this case, the two forming tools are arranged the same, so that the two arms or fingers 13,14 of the deformation tools attack alternately at the top and bottom of the paper layer 1 and the cushion layer 7.

In jedem Fall sind aber beide Verformwerkzeuge gleich ausgebildet, so dass bei jeder Drehung der Verformwerkzeuge 10 und 11 einmal das eine oben und das andere unten und nach 180° Drehung der Verformwerkzeuge die Verformwerkzeuge jeweils umgekehrt an der Papierlage 1 bzw. der Polsterlage 7 angreift.In any case, however, both deformation tools are the same design, so that with each rotation of the forming tools 10 and 11 once the one above and the other below and after 180 ° rotation of the forming tools, the forming tools in each case reversely engage the paper layer 1 or the cushion layer 7.

Durch das abwechselnde Angreifen der Verformwerkzeuge wird die Polsterlage 7 sehr voluminös aufgebauscht und erfährt eine Verdrehung, die dazu führt, daß diese auch sehr gut zusammenhält und sehr elastisch ist.By alternately attacking the forming tools, the cushion layer 7 is very bulged voluminous and undergoes a twist, which causes them to hold together very well and is very elastic.

Es ist auch möglich, die beiden Verformwerkzeuge an ihrem freien Ende abgerundet auszubilden.It is also possible to make the two forming tools rounded at their free end.

Darüber hinaus ist es möglich, die Verformwerkzeuge mit mehr als zwei Armen auszugestalten. Die beiden Verformwerkzeuge können innerhalb eines Formschachtes angeordnet, der im wesentlichen aus zwei seitlichen Führungsblechen 15 und 16 besteht. Am Ende des Formschachtes ist eine Abschneidvorrichtung 17 angeordnet, welche die Polsterpackung 7 in einzelne Längenabschnitte unterteilt.In addition, it is possible to design the deformation tools with more than two arms. The two forming tools can be arranged within a mold shaft, which essentially consists of two lateral guide plates 15 and 16. At the end of the forming shaft, a cutting device 17 is arranged, which divides the cushion pack 7 into individual lengths.

Zusätzlich zu den seitlich angreifenden Verformwerkzeugen ist - wie aus Fig.5 hervorgeht - unmittelbar vor den Verformwerkzeugen 10,11 eine Vorschubeinrichtung 18 angeordnet, die aus zwei Förderbändern 19 und 20 besteht. Die beiden Förderbänder haben einen so großen Abstand, daß die flachliegende Papierlage 1 gerade nicht erfaßt wird. Das eine der beiden Förderbänder ist mit einer Auflage 21 versehen, welche nur einen Längenabschnitt des Förderbandes einnimmt. Sobald sich diese Auflage zwischen den beiden Förderbändern befindet wird die Papierlage transportiert. Diese Vorschubeinrichtung 18 bzw. die Auflage 21 arbeiten intermittierend und zwar im wesentlichen unabhängig von den Verformwerkzeugen 10 und 11. Da die Vorschubeinrichtung schneller läuft als die Verformwerkzeuge, erfolgt eine Längsstauchung der Papierlage 1, wie dies mit 22 gekennzeichnet ist.In addition to the laterally attacking deformation tools is - like out Figure 5 shows - arranged immediately before the forming tools 10,11 a feed device 18, which consists of two conveyor belts 19 and 20. The two conveyor belts have such a large distance that the flat lying paper layer 1 is just not detected. One of the two conveyor belts is provided with a support 21, which occupies only a longitudinal section of the conveyor belt. As soon as this support is located between the two conveyor belts, the paper layer is transported. This feed device 18 or the support 21 operate intermittently and that is essentially independent of the forming tools 10 and 11. Since the feed device runs faster than the forming tools, there is a longitudinal compression of the paper layer 1, as indicated at 22.

Die am Ende angeordnete Abschneidvorrichtung 17 arbeitet erst dann, wenn die Verformwerkzeuge 10 und 11 nicht im Eingriff sind und damit kein wesentlicher Vorschub der Polsterpackung stattfindet.The arranged at the end cutting device 17 only works when the forming tools 10 and 11 are not engaged and thus no substantial feed of the cushion pack takes place.
