It is proposed that the central region (24) have a width dimension (26) which corresponds to at least approximately three times the thickness (16) of the cushioning material (12) or at least approximately 25% of an outer diameter (28) of the cushioning product (10) .

Description

Die Erfindung betrifft ein spulenförmiges Polsterungsprodukt für Verpackungszwecke nach dem Oberbegriff des Anspruchs 1.The invention relates to a coil-shaped upholstery product for packaging purposes according to the preamble of claim 1.

Grundsätzlich ist es bekannt, ein bahnförmiges flaches und insoweit im Wesentlichen zweidimensionales Ausgangsmaterial, beispielsweise eine flache aufgerollte Papierbahn, durch maschinelles Knüllen bzw. Stauchen in Bahn-Längsrichtung zu einem insoweit im Wesentlichen dreidimensionalen länglichen Polstermaterial umzuformen.Basically, it is known to convert a sheet-like flat and in this respect essentially two-dimensional starting material, for example a flat rolled-up paper sheet, by machine crumpling or upsetting in the lengthwise direction of the web into an essentially three-dimensional elongate cushioning material.

Eine entsprechende Vorrichtung ist beispielsweise aus der DE 10 2012 218 679 A1 bekannt. Bekannt ist ferner, dieses geknüllte längliche Polstermaterial zu einem spulenförmigen bzw. spiralförmigen Polsterungsprodukt aufzurollen bzw. aufzuwickeln. Dieses spulenförmige Polsterungsprodukt verfügt über die Fähigkeit, auch vergleichsweise schwere Gegenstände tragen zu können. Zur Herstellung des spulenförmigen Polsterungsprodukts wird das längliche Polstermaterial üblicherweise auf einer sich drehenden Haspel aufgewickelt bzw. aufgerollt, welche nach dem Aufrollen wieder entfernt wird. Ein Beispiel hierfür ist in der EP 1 027 214 B1 angegeben. In der noch nicht veröffentlichten DE 10 2017 113 532 sind ein Verfahren und eine Vorrichtung beschrieben, mittels denen ein spulenförmiges Polsterungsprodukt auch ohne Haspel hergestellt werden kann.A corresponding device is for example from the DE 10 2012 218 679 A1 known. It is also known to roll up or wrap this crumpled elongated cushioning material into a coil-shaped or spiral-shaped cushioning product. This coil-shaped upholstery product has the ability to carry even relatively heavy objects. To produce the coil-shaped upholstery product, the elongate upholstery material is usually wound up or rolled up on a rotating reel, which is removed again after being rolled up. An example of this is in the EP 1 027 214 B1 specified. In the not yet published DE 10 2017 113 532 describes a method and a device by means of which a coil-shaped upholstery product can also be produced without a reel.

Die vorliegende Erfindung hat die Aufgabe, ein spulenförmiges Polsterungsprodukt zu schaffen, welches besonders effizient eingesetzt werden kann.The object of the present invention is to create a coil-shaped upholstery product which can be used particularly efficiently.

Die gestellte Aufgabe wird durch ein spulenförmiges Polsterungsprodukt für Verpackungszwecke mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in Unteransprüchen angegeben.The object is achieved by a coil-shaped upholstery product for packaging purposes with the features of claim 1. Advantageous developments of the invention are specified in the subclaims.

Das erfindungsgemäße spulenförmige Polsterungsprodukt für Verpackungszwecke umfasst ein spulenförmig aufgerolltes bzw. aufgewickeltes, dreidimensionales und längliches Polstermaterial. "Dreidimensional" bedeutet vorliegend, dass es, anders als eine flache und ebene Papierbahn oder eine Folie im Vergleich zu seiner Breite eine maßgebliche und physikalisch wirksame, beispielsweise elastisch oder plastisch verformbare Dicke aufweist. Das Polsterungsprodukt weist einen Mittenbereich auf, in dem kein Polstermaterial, wie es außerhalb von dem Mittenbereich durch Aufrollen bzw. Aufwickeln vorliegt, vorhanden ist. Dies kann bedeuten, dass in diesem Mittenbereich ein Leerraum ist, kann aber auch bedeuten, dass in diesem Mittenbereich ein anderes Material vorhanden ist.The coil-shaped upholstery product according to the invention for packaging purposes comprises a three-dimensional and elongated cushioning material that is rolled up or wound up in a coil. In the present case, “three-dimensional” means that, unlike a flat and flat paper web or a film, it has a significant and physically effective, for example elastically or plastically deformable, thickness compared to its width. The upholstery product has a central area in which there is no upholstery material, such as is present outside of the central area by rolling up or winding up. This can mean that there is an empty space in this central area, but can also mean that another material is present in this central area.

Erfindungsgemäß wird vorgeschlagen, dass der Mittenbereich des spulenförmigen Polsterungsprodukts eine Weitendimension aufweist, die mindestens in etwa dem Dreifachen der Dicke des bahnförmigen Polstermaterials oder mindestens in etwa 25% eines Außendurchmessers des Polsterungsprodukts entspricht. Etwas umgangssprachlicher ausgedrückt bedeutet dies, dass das Polsterungsprodukt in seiner Mitte ein deutliches Loch aufweist, in dem kein Polstermaterial, wie es außerhalb von dem Mittenbereich durch Aufrollen vorliegt, vorhanden ist. Hierdurch wird Material gespart, wodurch die Kosten reduziert werden. Darüber hinaus können von einem Vorrat an bahnförmigem und noch zweidimensionalen oder bereits länglichen dreidimensionalen Polstermaterial mehr spulenförmige Polsterungsprodukte hergestellt werden, wodurch die Effizienz gesteigert wird. Auch sinkt das Gewicht eines spulenförmigen Polsterungsprodukts, was dessen Handhabung erleichtert.It is proposed according to the invention that the central region of the coil-shaped upholstery product has a width dimension which corresponds to at least approximately three times the thickness of the web-shaped upholstery material or at least approximately 25% of an outer diameter of the upholstery product. To put it more colloquially, this means that the upholstery product has a clear hole in its center, in which there is no upholstery material, such as is available outside of the central area by rolling it up. This saves material, which reduces costs. In addition, more coil-shaped upholstery products can be produced from a stock of web-shaped and still two-dimensional or already elongated three-dimensional upholstery material, as a result of which the efficiency is increased. The weight of a coil-shaped upholstery product also decreases, which makes it easier to handle.

Dies alles wird ermöglicht, ohne dass der primäre Zweck des Polsterungsprodukts, nämlich die gepolsterte Lagerung eines Gegenstands auf dem Polsterungsprodukt, leidet. Überraschenderweise wurde nämlich festgestellt, dass viele Gegenstände, welche auf dem Polsterungsprodukt angeordnet und durch dieses gelagert werden sollen, im Zentrum des Polsterungsprodukts nicht oder nicht wesentlich aufliegen, dort also auch nicht oder zumindest nicht wesentlich gepolstert gelagert sind. Stattdessen wurde festgestellt, dass es eher die radial äußeren Randbereiche des Polsterungsprodukts sind, die den auf dem Polsterungsprodukt abgelegten Gegenstand tragen.All of this is possible without sacrificing the primary purpose of the cushioning product, namely the cushioned storage of an object on the cushioning product. Surprisingly, it has been found that many objects which are to be arranged on the upholstery product and are stored by the latter do not lie or do not lie substantially in the center of the upholstery product, that is to say there are no or at least not substantially upholstered there. Instead, it was found that it is rather the radially outer edge regions of the upholstery product that carry the object placed on the upholstery product.

Eine Weiterbildung der Erfindung sieht vor, dass das Polstermaterial ein geknülltes Papier umfasst, vorzugsweise aus geknülltem Papier hergestellt ist. Dies ist preiswert und umweltfreundlich, da recyceltes Papier verwendet werden kann und das Polsterungsprodukt nach der Verwendung ebenfalls recycelt werden kann.A further development of the invention provides that the cushion material comprises crumpled paper, preferably made from crumpled paper. This is inexpensive and environmentally friendly, as recycled paper can be used and the upholstery product can also be recycled after use.

Eine Weiterbildung der Erfindung sieht vor, dass das Polstermaterial ein in seiner Längsrichtung geknülltes Papier umfasst. Ein solches Polstermaterial hat besonders gute Polstereigenschaften, was wiederum zu sehr guten Polstereigenschaften des spulenförmigen Polsterungsprodukts führt.A further development of the invention provides that the cushioning material comprises paper crumpled in its longitudinal direction. Such an upholstery material has particularly good upholstery properties, which in turn leads to very good upholstery properties of the coil-shaped upholstery product.

Eine Weiterbildung der Erfindung sieht vor, dass das Polstermaterial einen insgesamt wenigstens in etwa rechteckigen Querschnitt aufweist mit einer Dicke bzw.A further development of the invention provides that the cushioning material has an overall at least approximately rectangular cross section with a thickness or

Höhe, die wesentlich geringer ist als eine Breite. Eine aus einem solchen Polstermaterial hergestellte Spule hat eine vergleichsweise ebene Oberfläche, was die Anwendung erleichtert.Height that is significantly less than a width. A coil made from such a cushioning material has a comparatively flat surface, which makes it easier to use.

Eine Weiterbildung der Erfindung sieht vor, dass das Polstermaterial einen schlauchförmigen Querschnitt aufweist. Ein solches Polstermaterial hat eine vergleichsweise geringe Dichte, wodurch das Gewicht des spulenförmigen Polsterungsprodukts reduziert wird, was wiederum die Handhabung erleichtert.A further development of the invention provides that the cushioning material has a tubular cross section. Such a cushioning material has a comparatively low density, which reduces the weight of the coil-shaped cushioning product, which in turn makes handling easier.

Eine Weiterbildung der Erfindung sieht vor, dass die Weitendimension des Mittenbereichs eine minimale Weite ist. Dies spielt insbesondere dann eine Rolle, wenn der Mittenbereich keine symmetrische, beispielsweise kreisförmige Kontur hat. Auf diese Weise wird sichergestellt, dass der Mittenbereich ausreichend groß ist, um die erfindungsgemäßen Vorteile zu erzielen.A further development of the invention provides that the width dimension of the central area is a minimal width. This is particularly important if the central area has no symmetrical, for example circular, contour. This ensures that the central area is sufficiently large to achieve the advantages according to the invention.

Eine Weiterbildung der Erfindung sieht vor, dass der Mittenbereich wenigstens in etwa kreisförmig ist. Dies erleichtert die Handhabung, da bei der Anwendung nicht auf die Orientierung des spulenförmigen Polsterungsprodukts geachtet werden muss.A further development of the invention provides that the central area is at least approximately circular. This facilitates handling, since the orientation of the coil-shaped upholstery product does not have to be taken into account during use.

Funktionsäquivalente Bereiche und Elemente sind in den Figuren mit den gleichen Bezugszeichen versehen.Functionally equivalent areas and elements are provided with the same reference symbols in the figures.

Ein spulenförmiges Polsterungsprodukt trägt in den Figuren insgesamt das Bezugszeichen 10. Es hat die Form einer flachen und auf der Seite liegenden Schnecke bzw. Spule und umfasst ein spulenförmig aufgerolltes bzw. aufgewickeltes, dreidimensionales und längliches Polstermaterial 12, wobei eine Aufroll- bzw. Wickelachse 13 in der dargestellten Betriebslage vertikal ist. Das Polstermaterial 12 hat eine Breite bzw. Höhe 14 und eine Dicke 16. Man erkennt aus der Darstellung in Figur 1, dass "dreidimensional" vorliegend bedeutet, dass das Polstermaterial 12, anders als eine flache und ebene Papierbahn oder eine flache und ebene Folie, im Vergleich zu seiner Breite 14 eine maßgebliche Dicke 16 aufweist. In Richtung der Dicke 16 ist das Polstermaterial 12 ohne weiteres verformbar.A coil-shaped upholstery product bears the overall reference number 10 in the figures. It has the shape of a flat screw or coil lying on the side and comprises a three-dimensional and elongated cushion material 12 rolled up or wound up, with a roll-up or winding axis 13 is vertical in the operating position shown. The cushion material 12 has a width or height 14 and a thickness 16. It can be seen from the illustration in FIG Figure 1 that "three-dimensional" here means that the cushioning material 12, unlike a flat and flat paper web or a flat and flat film, has a significant thickness 16 in comparison to its width 14. The cushioning material 12 is easily deformable in the direction of the thickness 16.

Wie aus den Figuren 7 und 8 ersichtlich ist, kann das Polstermaterial 12 aus zwei flachen und ebenen und mittig verbundenen Papierbahnen 18 hergestellt sein, die beispielsweise an den Rändern umgeschlagen und dann in einer Längsrichtung 20 durch kontinuierliches Stauchen geknüllt wurden (Pfeile 22). Ein solches Polstermaterial 12 zeigen die Figuren 7 und 8, wobei in Figur 8 das Polstermaterial 12 nach dem Umschlagen der Ränder aber noch vor dem Knüllen (Pfeile 22) in der Längsrichtung 20 dargestellt ist. Dabei ist aus Figur 7 ersichtlich, dass das dort gezeigte Polstermaterial 12 einen insgesamt noch als rechteckig zu bezeichnenden Querschnitt aufweist mit einer Dicke 16, die merklich geringer ist als die Breite bzw. Höhe 14. Figur 9 zeigt ein Polstermaterial 12, welches einen schlauchförmigen Querschnitt aufweist und ebenfalls aus Papier hergestellt ist und in der Längsrichtung 20 entsprechend den Pfeilen 22 durch Stauchen geknüllt wurde.Like from the Figures 7 and 8 As can be seen, the cushioning material 12 can be produced from two flat and flat and centrally connected paper webs 18 which, for example, were folded over at the edges and then crumpled in a longitudinal direction 20 by continuous upsetting (arrows 22). Such a cushion material 12 show the Figures 7 and 8 , where in Figure 8 the cushioning material 12 after the edges have been turned over before crumpling (arrows 22) is shown in the longitudinal direction 20. It is over Figure 7 It can be seen that the cushioning material 12 shown there has a cross-section that can still be described as rectangular, with a thickness 16 that is noticeably less than the width or height 14. Figure 9 shows a cushion material 12 which has a tubular cross section and is also made of paper and has been crumpled in the longitudinal direction 20 according to the arrows 22 by upsetting.

Das Polsterungsprodukt 10 umfasst einen vorliegend beispielhaft in Richtung der Wickelachse 13 gesehen in etwa kreisförmigen Mittenbereich 24, in dem weder Polstermaterial 12 noch ein anderes Material vorhanden ist. Der Mittenbereich 24 ist insoweit ein Leerraum bzw. ein Loch. Er weist eine Weitendimension - vorliegend entsprechend etwa einem Innendurchmesser 26 - auf, die vorliegend beispielhaft in etwa dem 10-fachen der Dicke 16 des Polstermaterials 12 entspricht.The upholstery product 10 comprises an approximately circular central region 24, as seen here in the direction of the winding axis 13, in which neither upholstery material 12 nor any other material is present. In this respect, the central area 24 is an empty space or a hole. It has a width dimension - in the present case corresponding to an inner diameter 26 - which in the present case corresponds approximately to 10 times the thickness 16 of the cushioning material 12.

Hierdurch werden Material und Gewicht gespart. Dieser Effekt tritt mit merkbarer Relevanz bereits dann auf, wenn die Weitendimension 26 mindestens ungefähr dem Dreifachen der Dicke 16 des Polstermaterials 12 entspricht. Außerdem entspricht vorliegend die Weitendimension 26 beispielhaft in etwa 35 % eines Außendurchmessers 28 des Polsterungsprodukts 10. Auch diesbezüglich tritt der oben erwähnte Effekt mit merkbarer Relevanz bereits dann auf, wenn die Weitendimension 26 mindestens ungefähr 25 % des Außendurchmessers 28 entspricht.This saves material and weight. This effect occurs with a noticeable relevance when the width dimension 26 corresponds to at least approximately three times the thickness 16 of the cushion material 12. In addition, the width dimension 26 corresponds here by way of example to approximately 35% of an outer diameter 28 of the upholstery product 10. In this regard, too, the above-mentioned effect occurs with a noticeable relevance when the width dimension 26 corresponds to at least approximately 25% of the outer diameter 28.

In Figur 2 ist ein Einsatzszenario des Polsterungsprodukts 10 schematisch dargestellt. Man erkennt einen kastenförmigen und in der Seitenansicht rechteckigen Behälter 30 mit einem Boden 32 und Seitenwänden 34. Bei dem Behälter 30 kann es sich beispielsweise um einen Behälter 30 aus Karton oder aus Holz handeln. Das spulenförmige Polsterungsprodukt 10 ist flach, also mit vertikaler Wickelachse 13, auf den Boden 32 des Behälters 30 aufgelegt. Ein in dem Behälter 30 gepolstert zu transportierender Gegenstand 36 ist auf das Polsterungsprodukt 10 aufgelegt. Gegebenenfalls kann das Polsterungsprodukt 10 in dem Behälter 30 unverrückbar befestigt sein. Auch können zwischen dem Gegenstand 36 und den Seitenwänden 34 weitere Polsterungsprodukte, beispielsweise in Form von Polstermaterial 12, vorhanden sein, was in Figur 2 jedoch nicht dargestellt ist.In Figure 2 An application scenario of the upholstery product 10 is shown schematically. One recognizes a box-shaped container 30, which is rectangular in side view, with a bottom 32 and side walls 34. The container 30 can be a container 30 made of cardboard or wood, for example. The coil-shaped upholstery product 10 is placed flat, that is to say with a vertical winding axis 13, on the bottom 32 of the container 30. An object 36 to be transported padded in the container 30 is placed on the padding product 10. Optionally, the padding product 10 can be immovably secured in the container 30. Further padding products, for example in the form of cushioning material 12, can also be present between the object 36 and the side walls 34, which is shown in FIG Figure 2 but is not shown.

Die Herstellung des spulenförmigen Polsterungsprodukts 10 wird nun unter Bezugnahme auf die Figuren 3-6 erläutert: zur Herstellung des spulenförmigen Polsterungsprodukts 10 dient eine Vorrichtung 38. Diese umfasst ein mittels einer Vielzahl von Rollen (ohne Bezugszeichen) geführtes Band 40, welches entsprechend einem Pfeil 42 angetrieben ist. Gespannt wird das Band 40 durch eine durch ein Gewicht 44 belastete Rolle 46.The manufacture of the coil-shaped cushioning product 10 will now be described with reference to FIG Figures 3-6 Explanation: A device 38 is used to manufacture the coil-shaped upholstery product 10. It comprises a belt 40 guided by means of a plurality of rollers (without reference numerals), which is driven according to an arrow 42. The band 40 is tensioned by a roller 46 loaded by a weight 44.

Das geknüllte Polstermaterial 12, welches die Form beispielsweise von einem der in den Figuren 7-9 gezeigten Polstermaterialien 12 haben kann, wird in einer Umformungseinrichtung 48 aus einem bahnförmigen flachen Papiermaterial (nicht dargestellt) hergestellt. Von der Umformungseinrichtung 48 wird das Polstermaterial 12 zwischen den beiden Rollen 50 und 52 gegen das sich in Richtung des Pfeiles 42 bewegende Band 40 geführt (Figuren 3 und 4), wodurch das Band 40 eingedrückt und ein temporär vorhandener Aufwickelraum 54 gebildet wird (Figur 4). Durch eine entsprechende Einstellung der drei Parameter (a) Zuführgeschwindigkeit des Polstermaterials 12, (b) Bewegungsgeschwindigkeit des Bands 40 und (c) Vorspannung des Bands 40 durch das Gewicht 44 wird erreicht, dass sich das Polstermaterial 12 in dem Aufwickelraum 54 spulenförmig aufgewickelt, wobei jedoch in dem Mittenbereich 24 des entstehenden Polsterungsprodukts 10 ein Leerraum verbleibt (Figur 5).The crumpled upholstery material 12, which has the shape of, for example, one of the in the Figures 7-9 upholstery materials 12 shown, is in a Forming device 48 made of a sheet-shaped flat paper material (not shown). The cushioning material 12 is guided by the shaping device 48 between the two rollers 50 and 52 against the belt 40 moving in the direction of the arrow 42 ( Figures 3 and 4 ), whereby the band 40 is pressed in and a temporarily available winding space 54 is formed ( Figure 4 ). A corresponding setting of the three parameters (a) feeding speed of the cushioning material 12, (b) moving speed of the belt 40 and (c) pretensioning of the belt 40 by the weight 44 ensures that the cushioning material 12 is wound in a coil shape in the winding space 54, whereby however, an empty space remains in the central region 24 of the resulting upholstery product 10 ( Figure 5 ).

Ist die gewünschte Größe (Außendurchmesser 28) des Polsterungsprodukts 10 erreicht bzw. gelangt ein Ende 56 des zugeführten Polstermaterials 10 in den Aufwickelraum 54, wird der Aufwickelraum 54 durch eine Verschiebung von Rollen 56 geöffnet, so dass das fertig gestellte Polsterungsprodukt 10 nach unten (Pfeil 60) fällt. Das Ende 56 des Polstermaterials 10 kann dabei durch eine Klebestelle 62 am Rest des Polstermaterials 12 gesichert werden.If the desired size (outer diameter 28) of the upholstery product 10 has been reached or if one end 56 of the supplied upholstery material 10 has entered the take-up space 54, the take-up space 54 is opened by moving rollers 56 so that the finished upholstery product 10 is downward (arrow 60) falls. The end 56 of the cushioning material 10 can be secured to the rest of the cushioning material 12 by an adhesive point 62.
