Definitions
- the invention relates to a pallet for the transport of loads, consisting of two layers produced by suction molding, with cup-like open-top feet made of pulp-washed paper, cardboard and / or cellulose fiber waste, the two layers with their rough surfaces being sealed when wet are joined together and connected to each other.
- Pallets of this type are known, for example, from DE-U-94 13 164.3, for which it is also intended to form them from more than one suction mold layer. Even with training with two layers, however, the load capacity of such pallets is limited, and the object of the invention is to further improve the load capacity of a pallet of the type mentioned at the beginning.
- longitudinal and transverse ribs are arranged, for example, as a square or rectangular grid, there is also the possibility of arranging these grids diagonally in one and the other position.
- the lower layer has, for example, parallel longitudinal ribs which only extend in the longitudinal direction of the pallet and the other layer only has parallel transverse ribs.
- the upper layer is also formed with ribs, which will be the rule, it is advantageously provided to arrange a flat top layer of material that can also be recycled on this layer, ie its ribs.
- This top layer can of course only be applied and fastened in a suitable manner when the pallet has been formed from two layers, joined together and dried.
- such a top layer also contributes to increasing the stability of the pallet. For the rest, there would be nothing to also cover the ribbing of the lower layer with such a cover layer, which practically represented a pallet in sandwich construction.
- FIG. 2 shows two short sections of the two layers 1, 2 before the assembly.
- the pallet consists of the two layers 1, 2, on which in the corner regions the cup-like upright feet 3 are also formed.
- longitudinal and transverse ribs 6, 7 which intersect at both layers 1, 2 are present.
- This rib structure shown is only an example, ie significantly more ribs can be provided in close association with one another, it also being possible to occupy only selected areas with a denser rib arrangement. Ribs can also be arranged along the edges of the pallets. The above-mentioned design option of the rib or rib grid offset to one another is not shown, since it is readily conceivable.
- the upper layer 2 is provided with longitudinal and transverse ribs 6 ', 7', these or the pallet are covered with a cover layer 8, which is firmly connected to the pallet in a suitable manner, for example by gluing, Crimping or the like.
- the top layer 8 is provided with cutouts 9 so that the feet 3 of the subsequent pallet into the openings 10 of the pallet below can intervene.
- the size relationships of the sectional illustration in FIG. 3 correspond approximately to the actual conditions, i.e. the wall thicknesses of the layers 1, 2 which can be achieved by the suction molding process are approximately 5 to 10 mm.
- the shaping of the above-mentioned pallets already leads to a very substantial stabilization, this is additionally increased considerably according to the embodiments according to FIGS. 4 to 8 and also makes them more suitable for being able to be transported over bumpy conveyor lines.
- the feet 3 are well connected or anchored to the longitudinal or transverse strips 11, taking into account that the pallet material itself is at risk of tearing.
- the skids can be made of different materials, ie wood, sheet metal, multi-layer cardboard or the same material as the pallet itself (see in particular Fig. 7,8).
- the embodiment according to FIGS. 5, 6 is preferred with regard to the reusability of the skids or the longitudinal or transverse strips 11.
- FIG. 4 is intended for higher loads or stresses, in which the longitudinal or transverse strips 11 and also the pin 12 are made of wood, wherein the pin 12 can be nailed, screwed or glued to the strips 11.
- the embodiment according to FIG. 7 is of a special kind insofar as the longitudinal or transverse strips 11, like the pallet itself, are formed with their feet 3 made of suction-molded material and on which the pins 12 engaging in holes 13 are integrally formed.
- the longitudinal or transverse strips 11, as shown can have at least two layers, the base-side layer L being provided with the pins 12 engaging in the holes. Both layers L, L 'are also provided with stiffening ribs R each directed towards the other layer.
- Such longitudinal and transverse strips 11 can be produced in one piece, on which both the pins 12 and the ribs R are formed.
- FIGS. 5, 6 Because of their simplicity, but in particular also the ease with which the sliding curves or the longitudinal or transverse strips 11 can be detached from the pallet and thus reusable, the embodiment according to FIGS. 5, 6 is preferred, which also has the advantage of protecting the support feet 3 on the flanks and also that practically the entire bottom of the feet 3 can be braced with the respective longitudinal or transverse bar 11. 5, 6 show, the longitudinal or transverse strips 11 are formed from a with its legs 15 'in the direction of the feet 3 oriented u-sheet profile 15 with attached threaded pins 16 which reach through the bottoms 3''of the feet 3 and on which 17 screw connections 18 are fitted with the interposition of sufficiently large washers.
- the washers 17 advantageously correspond in diameter to the inner surface F of the bottoms 3 ′′, and the screw connections 18 are designed in the form of wing nuts.
- the threaded pins 16 can advantageously be designed to be insertable at their free ends, so that no holes have to be provided in the bottoms 3 ′′, but rather the threaded pins 16 can simply be inserted.
- FIGS. 5, 6 FIGS. 5, 6 (FIG. 6 shows the pallet in a view from below), as said, is preferred because it ensures maximum stability, the skids have a lower weight than correspondingly massive wooden runners and because this type of skids are most easily recyclable for re-equipped pallets made of pulp material, which of course only have a limited lifespan.

Abstract
Description
Die Erfindung betrifft eine Palette zum Transport von Lasten, bestehend aus zwei im Saugformverfahren hergestellten, mit napfartig nach oben offenen Aufstellfüßen versehenen Lagen aus als Pulpe aufgeschwemmten Papier-, Kartonage- und/oder Zellulosefaserabfällen, wobei die beiden Lagen mit ihren rauhen Flächen im Naßzustand dicht zusammengefügt und miteinander verbunden sind.The invention relates to a pallet for the transport of loads, consisting of two layers produced by suction molding, with cup-like open-top feet made of pulp-washed paper, cardboard and / or cellulose fiber waste, the two layers with their rough surfaces being sealed when wet are joined together and connected to each other.
Paletten dieser Art sind bspw. nach dem DE-U-94 13 164.3 bekannt, für die auch vorgesehen ist, diese aus mehr als einer Saugformlage zu bilden. Selbst bei Ausbildung mit zwei Lagen ist jedoch die Belastbarkeit solcher Paletten begrenzt, und der Erfindung liegt die Aufgabe zugrunde, eine Palette der eingangs genannten Art hinsichtlich ihrer Belastbarkeit weiter zu verbessern.Pallets of this type are known, for example, from DE-U-94 13 164.3, for which it is also intended to form them from more than one suction mold layer. Even with training with two layers, however, the load capacity of such pallets is limited, and the object of the invention is to further improve the load capacity of a pallet of the type mentioned at the beginning.
Diese Aufgabe ist mit einer Palette nach der Erfindung dadurch gelöst, daß an der unteren und/oder der oberen Lage zur die Saugsiebstruktur aufweisenden Fläche hin Längs- und/oder Querippen ausgeformt sind, deren Dicke die Größenordnung der Stärke der beiden Lagen hat und deren Höhe dem Zwei- bis Vierfachen ihrer Dicke entspricht.This object is achieved with a pallet according to the invention in that longitudinal and / or transverse ribs are formed on the lower and / or the upper layer towards the surface having the suction screen structure, the thickness of which has the order of magnitude of the thickness of the two layers and the height thereof corresponds to two to four times its thickness.
Paletten mit Längs- und Querrippen auszustatten, ist zwar nach der DE-A-29 18 573 bekannt, bei dieser Palette handelt es sich aber einerseits um ein Formpreßteil aus nur einer Lage und andererseits sind die zur Versteifung dienen sollenden Ausformungen Rinnen, die keine Lagenmaterialverstärkungen darstellen. Solche Rinnen würden, da relativ querschnittsgroß, bei im Saugformverfahren hergestellten Paletten der eingangs genannten Art zu keiner wesentlichen Verbesserung der Belastbarkeit führen. Demgegenüber stellen die Längs- und Querrippen der erfindungsgemäßen Palette Lagenverstärkungen dar, da es sich aufgrund der Maßgaben von Dicke, Lagenstärke und Höhe nicht um Hohlrippen handelt, sondern um Rippen aus "Vollmaterial".Equipping pallets with longitudinal and transverse ribs is known from DE-A-29 18 573, but this pallet is, on the one hand, a molded part made from only one layer and, on the other hand, the formations to be used for stiffening are grooves that do not reinforce the layer material represent. Such channels, since they are relatively large in cross section, would not lead to any significant improvement in the load-bearing capacity of pallets of the type mentioned at the outset. In contrast, the longitudinal and transverse ribs of the pallet according to the invention are layer reinforcements, since, due to the requirements of thickness, layer thickness and height, the ribs are not made of hollow ribs, but ribs made of "solid material".
Ausgehend von grundsätzlich zwei Lagen besteht für eine solche Palettenausbildung die Möglichkeit, deren Belastbarkeit, ggf. auf besondere Bedarfsfälle abstellen zu können, wofür natürlich immer entsprechende Saugformen vorliegen müssen.Starting from basically two layers, there is the possibility for such a pallet formation to be able to adjust its resilience, if necessary to special needs, for which of course appropriate suction forms must always be available.
So ist es möglich, bspw. nur die untere Lage mit Längs- und Querrippen zu versehen, wobei die Rippen mehr oder weniger dicht zueinander angeordnet werden können, was ebenfalls eine Einflußnahme auf die Belastbarkeit darstellt.It is thus possible, for example, to provide only the lower layer with longitudinal and transverse ribs, the ribs being able to be arranged more or less close to one another, which also influences the load-bearing capacity.
Gleiches gilt natürlich auch für die obere Lage. Weitere Maßnahmen, die zur Belastbarkeitsverbesserung führen, bestehen darin, daß man die Rippen in der einen Lage versetzt zu den Rippen der anderen Lage anordnet.The same naturally applies to the upper layer. Further measures which lead to an improvement in the load capacity consist in arranging the ribs in one layer offset from the ribs in the other layer.
Wenn Längs- und Querrippen bspw. als Quadrat- oder Rechteckraster angeordnet sind, besteht auch die Möglichkeit, diese Raster in der einen und anderen Lage diagonal zueinander anzuordnen.If longitudinal and transverse ribs are arranged, for example, as a square or rectangular grid, there is also the possibility of arranging these grids diagonally in one and the other position.
Möglich ist auch eine Ausführungsform, bei der die untere Lage bspw. sich nur in Palettenlängsrichtung erstreckende parallele Längsrippen aufweist und die andere Lage nur parallele Querrippen.An embodiment is also possible in which the lower layer has, for example, parallel longitudinal ribs which only extend in the longitudinal direction of the pallet and the other layer only has parallel transverse ribs.
Insbesondere für den Fall, daß auch die obere Lage mit Rippen ausgeformt ist, was die Regel sein wird, ist vorteilhaft vorgesehen, auf dieser Lage, d.h. deren Rippen, eine ebenflächige Decklage aus ebenfalls recyclebarem Material anzuordnen. Diese Decklage kann natürlich erst aufgebracht und in geeigneter Weise befestigt werden, wenn die Palette aus zwei Lagen ausgeformt, zusammengefügt und getrocknet ist. Abgesehen davon, daß damit die Verrippungsstruktur abgedeckt wird, trägt eine solche Decklage ebenfalls zur Stabilitätssteigerung der Palette bei. Im übrigen stünde nichts entgegen, auch die Verrippung der unteren Lage mit einer solchen Decklage abzudecken, was praktisch eine Palette in Sandwichbauweise darstellte.In particular in the event that the upper layer is also formed with ribs, which will be the rule, it is advantageously provided to arrange a flat top layer of material that can also be recycled on this layer, ie its ribs. This top layer can of course only be applied and fastened in a suitable manner when the pallet has been formed from two layers, joined together and dried. In addition to covering the rib structure, such a top layer also contributes to increasing the stability of the pallet. For the rest, there would be nothing to also cover the ribbing of the lower layer with such a cover layer, which practically represented a pallet in sandwich construction.
Eine besonders vorteilhafte und die Stabilität und Belastbarkeit der Palette erhöhende Weiterbildungsform ergibt sich nach den abhängigen Ansprüchen 6 bis 9.A particularly advantageous form of further training, which increases the stability and resilience of the pallet, results from the
Die erfindungsgemäße Palette wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The palette according to the invention is explained in more detail below with reference to the drawing of exemplary embodiments.

Die Saugausformung der beiden Lagen und auch deren Zusammenfügung im Naßzustand ist hinlänglich bekannt und bedarf keiner näheren Erläuterung. Zur Verdeutlichung dessen, was unter rauher Fläche 4 und die Saugsiebstruktur wiedergebenden Fläche 5 zu verstehen ist, wird auf Fig. 2 verwiesen, die zwei kurze Abschnitte der beiden Lagen 1, 2 vor dem Zusammenfügen darstellt.The suction molding of the two layers and also their assembly in the wet state is well known and requires no further explanation. In order to clarify what is to be understood by
Beim in Fig. 1 dargestellten Ausführungsbeispiel besteht die Palette aus den beiden Lagen 1, 2, an denen in den Eckbereichen die napfartig nach oben offenen Aufstellfüße 3 mit ausgeformt sind. Außerdem sind hierbei an beiden Lagen 1, 2 sich kreuzende Längs- und Querrippen 6, 7 vorhanden. Diese dargestellte Rippenstruktur ist nur beispielhaft, d.h., es können wesentlich mehr Rippen in dichter Zuordnung zueinander vorgesehen sein, wobei es auch möglich ist, nur ausgewählte Bereiche mit einer dichteren Rippenanordnung zu besetzen. Auch längs der Palettenränder können Rippen angeordnet werden. Nicht dargestellt ist die einleitend erwähnte Gestaltungsmöglichkeit des Rippen- bzw. Rippenrasterversatzes zueinander, da ohne weiteres vorstellbar.In the embodiment shown in Fig. 1, the pallet consists of the two
Sofern und wie dargestellt, die obere Lage 2 mit Längs- und Querrippen 6', 7' versehen ist, werden diese bzw. die Palette mit einer Decklage 8 abgedeckt, die in geeigneter Weise fest mit der Palette verbunden wird, bspw. durch Kleben, Verkrampen o. dgl. Um die Stapelbarkeit solcher Paletten zu erhalten, was in der Regel aus Lager- und Transportgründen häufig gefordert wird, ist die Decklage 8 mit Ausschnitten 9 versehen, so daß die Aufstellfüße 3 der Folgepalette in die Öffnungen 10 der darunter befindlichen Palette eingreifen können.If and as shown, the
Die Größenverhältnisse der Schnittdarstellung in Fig. 3 entsprechen in etwa den tatsächlichen Verhältnissen, d.h., die im Saugformverfahren erzielbaren Wandstärken der Lagen 1, 2 betragen etwa 5 bis 10 mm.The size relationships of the sectional illustration in FIG. 3 correspond approximately to the actual conditions, i.e. the wall thicknesses of the
Wesentlich ist nun, daß die Längs- und Querrippen 6, 7 bzw. 6', 7' keine Hohlrippen HR sind, wie dies nur zum Vergleiuch gestrichelt in Fig. 3 mit angedeutet ist, da solche Rippen, obgleich auch anwendbar, nicht so stabil sind, wie die hier tatsächlich vorgesehenen "Massivrippen", die bei entsprechender Gestaltung des Saugsiebes entstehen, d.h., die Nuten im Saugsieb müssen sowohl in der Breite als auch in der Höhe so bemessen sein, daß sich beim Saugformvorgang die Nuten voll ausfüllen können.It is now essential that the longitudinal and
Abgesehen davon, daß die Ausformung der vorbeschriebenen Paletten schon zu einer ganz wesentlichen Stabilisierung führt, wird diese nach den Ausführungsformen nach den Fig. 4 bis 8 zusätzlich beträchtlich erhöht und macht diese zudem besser geeignet, um über holperige Förderstrecken transportiert werden zu können. Wesentlich ist dabei, daß die Aufstellfüße 3 gut mit den Längs- oder Querleisten 11 verbunden bzw. verankert werden, wobei zu berücksichtigen ist, daß das Palettenmaterial an sich ausreißgefährdet ist. Je nach erwartbarer Beanspruchung können die Gleitkufen aus unterschiedlichem Material bestehen, d.h. aus Holz, Blech, mehrlagigen Kartonagen oder aber auch aus dem gleichen Material wie die Palette selbst (siehe hierzu insbesondere Fig.7,8). Bevorzugt mit Rücksicht auf die Wiederverwendbarkeit der Gleitkufen bzw. der Längs- oder Querleisten 11 wird die Ausführungsform nach den Fig. 5, 6.Apart from the fact that the shaping of the above-mentioned pallets already leads to a very substantial stabilization, this is additionally increased considerably according to the embodiments according to FIGS. 4 to 8 and also makes them more suitable for being able to be transported over bumpy conveyor lines. It is essential that the
Für höhere Belastungen bzw. Beanspruchungen ist das Ausführungsbeispiel nach Fig. 4 bestimmt, bei dem die Längs- oder Querleisten 11 und auch Zapfen 12 aus Holz bestehen, wobei die Zapfen 12 mit den Leisten 11 vernagelt, verschraubt oder aber auch verleimt sein können.The embodiment according to FIG. 4 is intended for higher loads or stresses, in which the longitudinal or
Das Ausführungsbeispiel gemäß Fig. 7 ist insofern von besonderer Art, als die Längs- oder Querleisten 11 wie die Palette selbst mit ihren Aufstellfüßen 3 aus sauggeformtem Material gebildet sind und an diesen die in Löcher 13 eingreifenden Zapfen 12 mit angeformt sind. Außerdem können die Längs- oder Querleisten 11, wie dargestellt, mindestens zweilagig ausgebildet sein, wobei die fußseitige Lage L mit den in die Löcher eingreifenden Zapfen 12 versehen sind. Beide Lagen L, L' sind hierbei zudem mit jeweils gegen die andere Lage gerichteten Versteifungsrippen R versehen. Die Herstellung solcher Längs- und Querleisten 11 kann dabei in einem Stück erfolgen, an dem sowohl die Zapfen 12 als auch die Rippen R ausgeformt sind.The embodiment according to FIG. 7 is of a special kind insofar as the longitudinal or
Was die Ausführungsform nach den Fig. 8 betrifft, so hat diese den Vorteil, daß an verfügbaren Saugformen und damit an den Paletten selbst nichts verändert werden muß (es müssen keine Durchgriffsöffnungen für die Zapfen 12 vorgesehen werden), sondern hierbei sind die Längs- bzw. Querleisten 11, egal aus welchem der vorgenannten Materialien diese gebildet sind, mit Eintiefungen 14 versehen, die dem bodenseitigen Querschnitt der Aufstellfüße 3 entsprechen, und in die die Aufstellfüße 3 in geeigneter Weise fixiert, vorzugsweise durch Klebung, eingesetzt sind. Handelt es sich dabei um Längs- bzw. Querleisten 11 aus dickem Karton oder Holz, so werden die Eintiefungen 14 bspw. eingefräst, und wenn es sich um Leisten aus Pulpmaterial oder aus dünnem Blech handelt, werden die Eintiefungen 14 mit eingeformt bzw. bei Blech eingeprägt.As far as the embodiment according to FIG. 8 is concerned, this has the advantage that nothing needs to be changed in the available suction molds and thus on the pallets themselves (no through openings for the
Wegen ihrer Einfachheit, insbesondere aber auch einfachen Lösbarkeit der Gleitkuven bzw. der Längs- oder Querleisten 11 von der Palette und damit Wiederverwendbarkeit wird die Ausführungsform nach den Fig. 5, 6 bevorzugt, die zudem noch den Vorteil eines flankenseitigen Schutzes der Aufstellfüße 3 hat und auch den, daß praktisch der ganze Boden der Füße 3 mit der jeweiligen Längs- bzw. Querleiste 11 verspannt werden kann. Wie dies Fig. 5, 6 zeigen, sind die Längs- oder Querleisten 11 aus einem mit seinen Schenkeln 15' in Richtung der Aufstellfüße 3 orientierten u-Blechprofil 15 mit aufgesetzten Gewindezapfen 16 gebildet, die die Böden 3'' der Aufstellfüße 3 durchgreifen und auf denen unter Zwischenlage von ausreichend großen Unterlegscheiben 17 Verschraubungen 18 aufgezogen sind. Vorteilhaft entsprechen dabei die Unterlegscheiben 17 im Durchmesser im wesentlichen der inneren Fläche F der Böden 3'', und die Verschraubungen 18 sind in Form von Flügelmuttern ausgebildet. Außerdem können vorteilhaft die Gewindezapfen 16 an ihren freien Enden einsteckbar spitz ausgebildet sein, so daß keine Löcher in den Böden 3'' vorgesehen werden müssen, sondern die Gewindezapfen 16 einfach eingestochen werden können.Because of their simplicity, but in particular also the ease with which the sliding curves or the longitudinal or
Die Ausführungsform nach Fig. 5, 6 (Fig. 6 stellt die Palette in Ansicht von unten dar) wird, wie gesagt, bevorzugt, weil diese ein Höchstmaß an Stabilität gewährleistet, die Gleitkufen ein geringeres Gewicht als entsprechend massive Holzkufen haben und weil diese Art von Gleitkufen am problemlosesten wiederverwertbar für erneut damit auszustattende Paletten aus Pulpmaterial sind, die natürlich nur eine begrenzte Lebensdauer haben.The embodiment according to FIGS. 5, 6 (FIG. 6 shows the pallet in a view from below), as said, is preferred because it ensures maximum stability, the skids have a lower weight than correspondingly massive wooden runners and because this type of skids are most easily recyclable for re-equipped pallets made of pulp material, which of course only have a limited lifespan.
Sofern solche Paletten per se nur als Einwegpaletten in Benutzung genommen werden und dies die erwartbare Belastung zuläßt, werden für solche Fälle Ausführungsformen bspw. gemäß Fig.7,8 verwendet, die insgesamt, d.h. mit den Gleitkufen recycelt werden können.If such pallets per se are only used as one-way pallets and this allows the expected load, embodiments are used for such cases, e.g. according to Fig. can be recycled with the skids.
Im übrigen sind in den Fig. 4 bis 8 alle an der Verbindung von Aufstellfüßen 3 und Gleitkufen beteiligten Elemente, d.h. als Kragen 3' ausgeformte Öffnungsbegrenzungen, die Zapfen 12 , Unterlegscheiben 17, Verschraubungen 18 zusätzlich mit VA bezeichnet, und zwar einschließlich der Eintiefungen 14.4 to 8 are all elements involved in the connection of
