Abstract

The padded packing making process produces a packing (7) from paper or other sheet material, which is put together and deformed by tools. Eventually, a folded-together cover layer (2) is produced, into which at least one intermediate layer (2,3) is inserted. These layers are then acted on by a deforming tool (10,11) from the narrow side. In addition to this deformation, the base, which is folded but still flat, is pushed forward intermittently to produce a deformation in the longitudinal direction.

Description

Verfahren zum Herstellen einer Polsterpackung aus Papier od.dgl. flächigen Gebilden, die zusammengelegt und durch Werkzeuge verformt wird, wobei eventuell in eine zusammenzufaltende Decklage wenigstens eine Zwischenlage eingelegt wird und die zusammengelegte Decklage zusammen mit der ggf. vorhandenen Zwischenlage von den Schmalseiten her mittels wenigstens eines Verformungswerkzeuges verformt wird.Method for producing a cushion pack from paper or the like two-dimensional structures which are folded together and deformed by tools, at least one intermediate layer possibly being placed in a cover layer to be folded and the folded cover layer together with the intermediate layer which may be present is deformed from the narrow sides by means of at least one deformation tool.

Zum Verformen derartiger Polsterpackungen werden bisher Zahnräder eingesetzt, die gleichzeitig auch den Vorschub des Papiers od.dgl. während des Verformvorganges bewirken. Bei Verwendung von Zahnrädern besteht jedoch die Gefahr, daß das Papier od.dgl. eingerissen wird und dann bei Benutzung leicht weiterreißt.To deform such cushion packs, gears have been used so far, which at the same time also feed the paper or the like. cause during the molding process. When using gears, however, there is a risk that the paper or the like. is torn and then tears easily when used.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren vorzuschlagen, mit dem eine zwar sehr effektive Verformung durchführbar ist, bei dem die Verformung jedoch sehr materialschonend erfolgt.The invention has for its object to propose a method with which a very effective deformation can be carried out, but in which the deformation takes place very gently.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß zusätzlich zur Verformung durch das Verformwerkzeug ein intermittierender Vorschub auf die noch flachliegende aber zusammengefaltete Lage einwirkt, welcher eine Verformung in Längsrichtung bewirkt.This object is achieved in that, in addition to the deformation by the forming tool, an intermittent feed on the still lying but folded position acts, which causes a deformation in the longitudinal direction.

Dadurch wird sowohl eine Verformung von den Seitenrändern her und als auch ein Zusammenstauchen der Lage in Längsrichtung erzielt, so daß beide Verformvorgänge mit geringerer Intensität und damit entsprechend schonend ausgeführt werden können.As a result, both a deformation from the side edges and a compression of the layer in the longitudinal direction is achieved, so that both deformation processes can be carried out with less intensity and therefore correspondingly gentle.

Es genügt dabei auch, wenn die Lage nur lose zusammengefaltet ist, wobei sich eine Überlappung der beiden Ränder als vorteilhaft ergeben hat.It is also sufficient if the layer is only folded up loosely, an overlap of the two edges having proven advantageous.

Eine vorteilhafte Ausgestaltung der Erfindung liegt auch darin, daß die beiden Randstreifen der Decklage nur bis zu einer geringfügigen Überlappung übereinander gefaltet und eventuell durch Kleben oder dergleichen verbunden werden.An advantageous embodiment of the invention also lies in the fact that the two edge strips of the cover layer are folded over one another only to a slight overlap and are possibly connected by gluing or the like.

Auch bei einer nur geringfügigen Überlappung der Randstreifen ist durch die zuerst eingeleitete Längsstauchung eine einwandfreie Polsterpackung herstellbar; durch eine zusätzliche Klebung kann jedoch bei höhergradigen Verformungen eine noch größere Stabilität der Polsterpackung erzielt werden.Even if there is only a slight overlap of the edge strips, a perfect cushion pack can be produced by the longitudinal compression introduced first; with additional gluing, however, even greater stability of the cushion pack can be achieved in the case of higher-level deformations.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist gegeben, wenn die beiden Randstreifen der Decklage sich nicht überlappen und eventuell beide mit einer jeweils benachbarten Zwischenlage durch Kleben verbunden sind.A further advantageous embodiment of the invention is provided when the two edge strips of the cover layer do not overlap and possibly both are connected to an adjacent intermediate layer by gluing.

Als sehr vorteilhaft hat es sich erwiesen, wenn gemäß einer weiteren Ausgestaltung der Erfindung die Zwischenlage höchstens die Breite der zusammengefalteten Decklage aufweist.It has proven to be very advantageous if, according to a further embodiment of the invention, the intermediate layer has at most the width of the folded top layer.

Hierdurch ist sowohl ein einfaches Zusammenfalten als auch eine leichte Verformbarkeit gegeben.This results in both simple folding and easy deformability.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, daß die Randbereiche der Decklage auf der Ober- oder Unterseite der Polsterpackung angeordnet werden, während die Verformwerkzeuge an den Seitenrändern der Polsterpackung angreifen.Another advantageous embodiment of the invention is that the edge regions of the cover layer are arranged on the top or bottom of the cushion pack, while the shaping tools engage on the side edges of the cushion pack.

Eine vorteilhafte Ausgestaltung der Erfindung ist auch dadurch gegeben, daß in Förderrichtung der Polsterpackung hinter den Verformwerkzeugen ein Querschneider vorgesehen ist, welcher Abschnitte der Polsterpackung quer zur Förderrichtung vom Polsterpackungs-Strang abtrennt.An advantageous embodiment of the invention is also provided in that a cross cutter is provided in the conveying direction of the cushion pack behind the shaping tools, which cuts off sections of the cushion pack transversely to the conveying direction from the cushion pack strand.

Eine vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahrens ist dadurch gekennzeichnet, daß der Querschneider aktiviert wird, wahrend die Polsterpackung frei von den seitlichen Verformwerkzeugen ist.An advantageous embodiment of the method according to the invention is characterized in that the cross cutter is activated while the cushion pack is free of the lateral shaping tools.

Da der durch die seitlichen Verformwerkzeuge bewirkte Vorschub in diesem Moment nicht stattfindet und damit die Polsterpackung höchstens unwesentlich weitertransportiert wird, ist ein einwandfreies Abtrennen durch den Querschneider gewährleistet.Since the feed caused by the lateral shaping tools does not take place at this moment and the cushion pack is at most insignificantly transported on, a perfect separation by the cross cutter is guaranteed.

Eine äußerst vorteilhafte Ausgestaltung des erfindungsgemäßen Verfahren liegt darin, daß die intermittierend aufgebrachte Vorschubgeschwindigkeit der noch flachliegenden Lage höher ist als die Transportgeschwindigkeit der Verformwerkzeuge.An extremely advantageous embodiment of the method according to the invention is that the intermittently applied feed speed of the still flat layer is higher than the transport speed of the forming tools.

Dadurch wird bei wirksamer Vorschubgeschwindigkeit ein Zusammenstauchen der Lage in Längsrichtung erzielt, an welches sich die Querverformung anschließt.In this way, with effective feed speed, the position is compressed in the longitudinal direction, which is followed by the transverse deformation.

Eine vorteilhafte Ausgestaltung einer Polsterpackung ist dadurch gekennzeichnet, daß eine zusammengefaltete Decklage vorgesehen ist, die evtl. wenigstens eine Zwischenlage umhüllt, und daß die Polsterpackung an wenigstens einem ihrer Längsränder mit nach innen gerichteten Einprägungen versehen ist, und daß in Längsrichtung der Polsterpackung Verformungen in Form von quer zur Längsrichtung verlaufenden Stauchungen vorgesehen sind.An advantageous embodiment of a cushion pack is characterized in that a folded top layer is provided, which possibly covers at least one intermediate layer, and that the cushion pack is provided with inwardly directed embossments on at least one of its longitudinal edges, and that in Longitudinal direction of the upholstery pack Deformations in the form of compressions running transversely to the longitudinal direction are provided.

Eine derartige Polsterpackung hat sich zum Abstützen von zu verpackenden Gegenständen hervorragend bewährt, wobei zumindest für die Zwischenlage preisgünstig herzustellendes Papier od.dgl. eingesetzt werden kann. Aber auch die Decklage kann aus wenig reißfestem Papier od.dgl. bestehen, da durch die getrennt hergestellten Einprägungen und Längsstauchungen eine hohe Materialschonung gegeben ist.Such a cushion pack has proven to be excellent for supporting objects to be packaged, at least for the intermediate layer or the like inexpensively produced paper. can be used. But also the top layer can be made of little tear-resistant paper or the like. exist, because the separately manufactured embossings and longitudinal compressions are very gentle on the material.

Für besondere Einsatzzwecke kann eine weitere Ausgestaltung der erfindungsgemäßen Polsterpackung sehr vorteilhaft sein, bei der die beiden Randstreifen der Decklage durch Verkleben miteinander bzw. mit einer benachbarten Zwischenlage festgelegt sind, wobei die Klebenaht an einer Breitseite angeordnet ist, während die Verformungen an den Schmalseiten vorgesehen sind.For special purposes, a further embodiment of the cushion pack according to the invention can be very advantageous, in which the two edge strips of the cover layer are fixed by gluing together or with an adjacent intermediate layer, the adhesive seam being arranged on a broad side, while the deformations are provided on the narrow sides .

Eine vorteilhafte Vorrichtung ist erfindungsgemäß dadurch gekennzeichnet, daß eine Falteinrichtung vorgesehen ist, in welcher eine Decklage der Polsterpackung so zusammengefaltet wird, daß sich eine wenigstens weitgehend geschlossene Hülle bildet.An advantageous device according to the invention is characterized in that a folding device is provided in which a cover layer of the cushion pack is folded up in such a way that an at least largely closed envelope is formed.

Eine vorteilhafte weitere Ausgestaltung der Erfindung liegt darin, daß eine Zufuhrvorrichtung vorgesehen ist, mit welcher wenigstens eine Zwischenlage in die Hülle eingebracht wird.An advantageous further embodiment of the invention is that a feed device is provided with which at least one intermediate layer is introduced into the casing.

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

Erfindungsgemäß ist es auch möglich, einen Formschacht vorzusehen, in welchem wenigstens ein Verformwerkzeug angeordnet ist, das an einem Seitenrand der Decklage angreift.According to the invention, it is also possible to provide a molding shaft in which at least one shaping tool is arranged which engages on a side edge of the cover layer.

Eine weitere vorteilhafte Ausgestaltung der Erfindung liegt darin, daß zwei nebeneinander angeordnete Verformwerkzeuge vorgesehen sind, die synchron zueinander angetrieben sind und die Polsterpackung zwischen sich einspannen und verformen.A further advantageous embodiment of the invention resides in the fact that two shaping tools arranged next to one another are provided, which are driven synchronously with one another and clamp and deform the cushion pack between them.

Eine weitere vorteilhafte Ausgestaltung der Erfindung ist dadurch gekennzeichnet, daß die Verformwerkzeuge drehbar gelagert und gegenläufig angetrieben sind, und daß die Verformwerkzeuge jeweils wenigstens einen Verformarm aufweisen.A further advantageous embodiment of the invention is characterized in that the shaping tools are rotatably mounted and driven in opposite directions, and in that the shaping tools each have at least one shaping arm.

Damit ist eine einfache Herstellung der Verformwerkzeuge und deren sicherer Betrieb gewährleistet.This ensures simple manufacture of the forming tools and their safe operation.

Bei einer weiteren Ausgestaltung der Erfindung ist vorgesehen, daß jedes Verformwerkzeug zwei diametral gegenüberliegende Verformarme aufweist.In a further embodiment of the invention it is provided that each shaping tool has two diametrically opposed shaping arms.

Eine derartige Ausgestaltung mit zwei Verformarmen hat sich als besonders vorteilhaft ergeben, wobei allerdings auch mehr Verformarme denkbar sind.Such an embodiment with two deformation arms has proven to be particularly advantageous, although more deformation arms are also conceivable.

Ebenfalls sehr vorteilhaft ist es, wenn gemaß einer weiteren Ausgestaltung der Erfindung jeder Verformarm an seinem freien Ende wenigstens zwei Verformfinger aufweist.It is also very advantageous if, according to a further embodiment of the invention, each deforming arm has at least two deforming fingers at its free end.

Dadurch wird eine noch effektivere Verformung der Polsterpackung erzielt.This results in an even more effective deformation of the cushion pack.

Sehr vorteilhaft ist es auch, wenn gemäß einer weiteren Ausgestaltung der Erfindung hinter den Verformwerkzeugen ein Querschneider angeordnet ist.It is also very advantageous if, according to a further embodiment of the invention, a cross cutter is arranged behind the shaping tools.

Dabei ist es auch möglich, daß der Querschneider am Ende des Formschachtes angeordnet ist.It is also possible for the cross cutter to be arranged at the end of the molding shaft.

Als sehr vorteilhaft hat sich auch eine weitere Ausgestaltung der Erfindung erwiesen, bei welcher der Querschneider ein hin und her bewegtes Schneidmesser aufweist, das gegen ein am Ende des Formschachtes angeordnetes Gegenwerkzeug arbeitet.A further embodiment of the invention has also proven to be very advantageous, in which the cross cutter has a reciprocating cutting knife which works against a counter tool arranged at the end of the mold shaft.

Eine weitere, sehr 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, very advantageous embodiment of the invention is characterized in that in the direction of movement of the layer or the cushion pack in front of the shaping tools, an intermittently operating feed device is provided for the still lying position, the transport speed of which is higher than that of the shaping tools.

Mit dieser Vorrichtung läßt sich auf einfache und zuverlässige Weise eine Polsterpackung aus Papier od.dgl. flächigem Material herstellen.With this device, a cushion pack made of paper or the like can be easily and reliably. Produce flat material.

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.1 in FIG. 1 denotes a flat-lying paper layer, which consists of a cover layer 2 and two intermediate layers 3 and 4. The top layer 2 is around the two Intermediate layers 3 and 4 are folded around, the two edge strips 5 and 6 of the cover layer being arranged on the top of the paper layer 1 and overlapping one another.

Dabei können die beiden Randstreifen lose aufeinander liegen oder miteinander verklebt sein.The two edge strips can lie loosely on top of one another or can be glued together.

Auch ist es möglich die beiden Randstreifen nur aneinander stoßen oder mit einem Abstand voneinander enden zu lassen.It is also possible to only abut the two edge strips or to have them end at a distance from one another.

Wird in den beiden letzten Fällen eine höhere Festigkeit gewünscht, so können die beiden Randstreifen mit der benachbarten Zwischenlage verklebt werden.If greater strength is required in the last two cases, the two edge strips can be glued to 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 top layer 2 as well as for the intermediate layer, any other flat material, such as 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 even several; you can also work without 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.After its production, this paper layer 1 can be rolled up and fed to a separate forming station or directly to a shaping device. A cushion pack 7 is then created, which has approximately the shape shown in FIG. 2 and is very suitable for cushioning 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 zwei Finger 13 auf, wie dies beim Verformwerkzeug 10 dargestellt ist oder drei Finger 14, wie dies anhand des Verformwerkzeuges 11 gezeigt ist. In jedem Fall sind aber beide Verformwerkzeuge gleich ausgebildet. Es ist auch möglich, die beiden Verformwerkzeuge an ihrem freien Ende abgerundet auszubilden. Darüber hinaus ist es möglich, die Verformwerkzeuge mit mehr als zwei Armen auszugestalten. Die beiden Verformwerkzeuge sind innerhalb eines Formschachtes angeordnet, der im wesentlichen aus zwei seitlichen Führungsblechen 15 und 16 besteht. Am Ende des Formschachtes ist ein Querschneider 17 angeordnet, welcher die Polsterpackung 7 in einzelne Längenabschnitte unterteilt.3 shows a device for reshaping the paper layer 1 into a cushion pack 7. For this purpose, two oppositely driven forming tools 10 and 11 are provided, which are synchronized via a gear pair, not shown. The two shaping tools 10, 11 are designed with two arms and both have either two fingers 13, as is shown in the shaping tool 10, or three fingers 14, as is shown using the shaping tool 11. In any case, however, both shaping tools are of the same design. It is also possible to round the two shaping tools at their free end. Beyond that it is possible to design the forming tools with more than two arms. The two shaping tools are arranged within a molding shaft, which essentially consists of two lateral guide plates 15 and 16. At the end of the shaped shaft, a cross cutter 17 is arranged, which divides the cushion pack 7 into individual lengths.

Zusätzlich zu den seitlich angreifenden Verformwerkzeugen ist - wie aus Fig.4 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 den Verformwerkzeugen 10 und 11. D.h. zwischen den seitlichen Verformwerkzeugen und der Vorschubeinrichtung sind Zahnradverbindungen mit sogenannten Primzahnrädern vorgesehen, wodurch ein weitgehend unabhängiger Antrieb erreicht ist. 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 acting shaping tools - as can be seen in FIG. 4 - a feed device 18 is arranged directly in front of the shaping tools 10, 11 and consists of two conveyor belts 19 and 20. The two conveyor belts are so far apart that the flat paper layer 1 is just not being grasped. One of the two conveyor belts is provided with a support 21, which only occupies a longitudinal section of the conveyor belt. As soon as this support is between the two conveyor belts, the paper layer is transported. This feed device 18 or the support 21 work intermittently and essentially independently of the shaping tools 10 and 11. Gear connections with so-called prime gears are provided between the lateral shaping tools and the feed device, whereby a largely independent drive is achieved. Since the feed device runs faster than the shaping tools, there is a longitudinal compression of the paper layer 1, as indicated by 22.

Der am Ende angeordnete Querschneider 17 arbeitet erst dann, wenn die Verformwerkzeuge 10 und 11 nicht im Eingriff sind un damit kein wesentlicher Vorschub der Polsterpackung stattfindet.The cross cutter 17 arranged at the end only works when the shaping tools 10 and 11 are not in engagement and therefore no substantial advance of the cushion pack takes place.
