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 flat structures, which is folded and deformed by tools, possibly in one at least one intermediate layer is to be folded and the folded top layer together with any intermediate layer of the narrow sides are deformed by means of at least one shaping 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.Gears have so far been used to deform such cushion packs at the same time the feed of the paper or the like. during the forming process cause. 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 very effective deformation is feasible, but the deformation is very done 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 an intermittent feed through the forming tool to the one that is still lying flat but folded position acts, which causes deformation in the longitudinal direction causes.

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.This causes both a deformation from the side edges and a Compression of the position in the longitudinal direction is achieved, so that both deformation processes can be carried out with less intensity and therefore accordingly gently.

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 loosely folded, whereby one Overlap of the two edges has been found to be 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 is that the two Margins of the top layer only overlap to a slight extent folded and 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 marginal strips, the first initiated longitudinal compression a flawless cushion pack can be produced; by a however, additional gluing can be even greater in the case of higher-level deformations Stability of the cushion pack can be achieved.

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.Another advantageous embodiment of the invention is given when the two Edge strips of the top layer do not overlap and possibly both with one each adjacent liner are connected 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 Invention the intermediate layer at most the width of the folded top layer having.

Hierdurch ist sowohl ein einfaches Zusammenfalten als auch eine leichte Verformbarkeit gegeben. This is both a simple folding and an easy one 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 areas of the top layer on the top or bottom of the cushion pack be arranged while the forming tools on the side edges of the Attack 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 given in that in Direction of conveyance of the cushion pack behind the forming tools a cross cutter it is provided which sections of the cushion pack transverse to the conveying direction from Pad pack strand separates.

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

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.Because the feed caused by the side forming tools at this moment does not take place and therefore the cushion pack is at most insignificant is transported, is a perfect separation by the cross cutter 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 lies in that the intermittently applied feed rate of the still lying flat is higher than the transport speed of the Shaping tools.

Dadurch wird bei wirksamer Vorschubgeschwindigkeit ein Zusammenstauchen der Lage in Längsrichtung erzielt, an welches sich die Querverformung anschließt.As a result, the effective feed rate will compress the Position achieved 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, possibly at least one Liner wrapped, and that the cushion pack on at least one of them Longitudinal edges are provided with inward impressions, and that in Longitudinal direction of the cushion pack deformations in the form of transverse to the longitudinal direction extending compressions 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 been used to support packaged items Objects have proven to be excellent, at least for the liner inexpensive paper or the like. can be used. But also the Top layer can be made of little tear-resistant paper or the like. exist as separated by the manufactured impressions and longitudinal compression a high material protection given is.

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.A further embodiment of the invention can be used for special purposes Upholstery pack can be very beneficial when the two edge strips of the topsheet fixed by gluing together or with an adjacent intermediate layer are, the adhesive seam is arranged on a broad side, while the Deformations are provided on the narrow sides.

The top layer 2 is around the two Intermediate layers 3 and 4 folded around, the two edge strips 5 and 6 of the Cover layer are arranged on the top of the paper layer 1 and overlap each other.

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

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 with one Distance from each other.

Wird in den beiden letzten Fällen eine höhere Festigkeit gewünscht, so können die beiden Randstreifen mit der benachbarten Zwischenlage verklebt werden.If a higher strength is required in the last two cases, the two edge strips are 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, both for the top layer 2 and for the intermediate layer 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 have only one intermediate layer or several provide; 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.This paper layer 1 can be rolled up after its production and a separate one Forming station or directly to a molding device. there a cushion pack 7 is then created, which is approximately the one shown in FIG Has shape and is very well suited 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 shown. For this purpose there are two shaping tools 10 and 11 driven in opposite directions provided, which are synchronized via a gear pair, not shown. The Both deformation tools 10, 11 are designed with two arms and both have either two fingers 13, as shown in the forming tool 10 or three fingers 14, as shown using the shaping tool 11. In any case but both forming tools are designed the same. It is also possible for the two Form deformation tools rounded at their free end. Beyond that it is possible to design the forming tools with more than two arms. The two forming tools are arranged within a mold shaft, which in the essentially consists of two lateral guide plates 15 and 16. At the end of Shaped shaft, a cross cutter 17 is arranged, which the cushion pack 7 in divided 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 forming tools - as in Fig. 4 emerges - a feed device immediately in front of the shaping tools 10, 11 18 arranged, which consists of two conveyor belts 19 and 20. The two Conveyor belts are so far apart that the flat paper layer 1 is not currently recorded. One of the two conveyor belts has a support 21 provided which occupies only a length of the conveyor belt. As soon as this support is located between the two conveyor belts, the paper layer transported. This feed device 18 or the pad 21 work intermittently and essentially independently of the forming tools 10 and 11. That means between the side shaping tools and the feed device gear connections with so-called prime gears are provided, whereby a largely independent drive is reached. Because the feeder faster runs as the forming tools, there is a longitudinal compression of the paper layer 1, such as this is marked with 22.

Der am Ende angeordnete Querschneider 17 arbeitet erst dann, wenn die Verformwerkzeuge 10 und 11 nicht im Eingriff sind und damit kein wesentlicher Vorschub der Polsterpackung stattfindet.The cross cutter 17 arranged at the end only works when the Deforming tools 10 and 11 are not in engagement and therefore not essential Advance of the cushion pack takes place.
