Definitions
- the invention relates to a stacking device for pallets in order to be able to stack a second pallet on a first pallet.
- Pallets are used in freight transport for the transport and storage of goods of all kinds as disposable pallets or in exchange.
- the pallets are made of wood with two or three in one direction parallel and resting on the ground straps on which transverse strips and cover boards are arranged.
- the cover boards provide a loading area onto which a storage or transport goods, e.g. Cartons, can be provided.
- a storage or transport goods e.g. Cartons
- tapes or foils are used to secure the load.
- the arrangement of the resting on the ground carrier allows underrun with the fork of a material handling vehicle, such as a lift truck or a forklift.
- a material handling vehicle such as a lift truck or a forklift.
- Euro pallet has established a standardized pallet size, but pallets of different sizes are regularly in use.
- Pallets are versatile and inexpensive. In comparison to the much more expensive and complex lattice boxes, however, the lack of stackability is disadvantageous for loaded pallets.
- Another known way of stacking pallets is to provide bent sheet metal spacers available from the aftermarket. These are placed at the four corners on the first lower pallet, so that a second pallet can be placed on top of the spacers.
- This solution is only suitable for storage, but not for transport purposes.
- An advantage of this solution is that it can be used for different pallet sizes.
- the publication DE 1 481 381 A1 describes a framework for placement on a pallet having two parallel opposed rigid frames which are interconnected at their sides by two scissor mechanisms.
- the scaffolding can be pulled apart in a position of use up to stops and be placed with corner fittings on the lower of two pallets.
- the second pallet can be placed. Due to the rigid design of the parallel frame and the attacks on the scissors stability is achieved in the position of use, which also allows a transport of pallets stacked in this way. However, depending on the loading of the lower pallet, the rigid design possibly leads to empty spaces between the pallets, as a result of which the transport capacity remains unused. Due to the scissors, the scaffolding can be folded flat during the return transport without the pallets, whereby little space is required.
- a stacking device is characterized by four U-shaped profiled corner posts, wherein sections of the corner posts can rest in each case in a corner region of the first pallet on outer sides of the first pallet. Two of the adjacent corner posts are connected to each other via a side strut. Each corner post also has a support element which is supported in the respective corner region on an upper side of the pallet. In or on each corner post an upwardly extendable support is guided, wherein at an upper, free end of the support a receptacle is mounted for each corner of a second pallet.
- the Upwardly extendable support is preferably lockable in different positions. In this way, the stack height, ie the distance between the first and the second pallet, can be adjusted as needed.
- the stack height can also be increased deliberately to create a free space above the stored goods of the first range, which allows easier access to the stored goods.
- a perforated strip may be provided, in which a bolt or screw is pushed through to set the support at a suitable height in the corner post.
- the support element may be fixed, in particular e.g. be joined by welding material fit with the corner posts.
- the support element is height-adjustable relative to the corner post in order to be able to adapt the stacking device to pallets of different thickness by changing the position of the support element.
- the height-adjustable support element is connected to the upwardly extendable support.
- weight forces of the upper second pallet or all other pallets stacked thereon are transmitted directly via the extendable support and the support element to the lower, first pallet.
- the corner posts themselves do not need to absorb the weight forces, but serve to guide the supports and the absorption of lateral forces.
- An inevitable friction between the corner posts and the columns and the corner posts and the first pallet prevents slipping of the corner posts when lifting the first pallet.
- the connection between the support and support element can in turn be adjustable in each case, for example by means of a row of holes in the support in order to vary the stack height.
- the telescopic side struts are telescopic, whereby the stacking device can be used for pallets of different sizes.
- the telescopic side struts comprise two intermeshing and mutually displaceable sections (sections). These may e.g. be formed by rails with a u- or c-shaped and interlocking profile. It can turn rows of holes, possibly provided with slots to fix the telescopic side struts in appropriate lengths. Other locking or clamping means to fix the telescopic side struts in their length, can be used.
- At least one of the side struts is pivotally mounted at both ends via a respective pivot bearing about a horizontal axis to the associated corner post.
- the side strut can be folded away, in particular folded down, to see even with stacked pallet whose stored goods from the side and possibly also to remove or to be able to add stored goods.
- the side struts can be firmly connected to the side cheeks of the corner posts or designed to be removable. It is particularly advantageous if the side struts extending in one direction of the pallets are firmly connected to the two respective corner posts, whereas the lateral struts extending transversely thereto are detachably detachable, for example by means of a screwed or optionally secured hooking connection, so that these side struts can be removed .
- the stacker can then be separated into two elongated units (two each connected via the fixed side strut corner posts) and two separate side struts. These can be transported flat on top of each other without taking up a large transport volume.
- all or part of the side struts may be e.g. be attached by hinges to the corner posts, so that they are horizontally pivotable.
- An unused stacking device which is not arranged around a pallet, can be folded flat by the hinges for transport purposes.
- the corner posts and / or the supports and / or the side struts or the sections telescopic side struts wholly or partly made of a metal sheet, in particular in a stamping and bending process.
- the pallet 1 which is an example of a Euro pallet and is made in standardized dimensions of wooden blocks and wooden boards, has two outer support 2 and a center support 3. These are arranged so that in the longitudinal direction of the pallet 1, a fork of a lift truck or a forklift can be inserted to lift the pallet 1 and to be able to load.
- Outer support 2 and the center support 3 are interconnected via transverse strips 4, on which in turn cover boards 5 are fixed, which form a loading area of the pallet 1.
- the stacking device 10 has four corner posts 11, which are preferably made of folded sheet metal material and each have two substantially mutually perpendicular side cheeks 111.
- the corner posts 11 lie with the side walls 111 on the outside of the pallet 1, specifically in the area of Eckklötzen the outer support. 2
- Each adjacent corner posts 11 are connected by side struts 14, 15 with each other.
- side struts 14, 15 In the longitudinal direction of the pallet 1 longer and also in their cross-section wider side struts 14 are used and along the transverse side of the pallet 1 shorter and smaller in cross section side struts 15th
- the side struts 14, 15 are each advantageously telescopic, e.g. by inserting two telescoping sections (sections).
- the side struts 14, 15 may for example be constructed of two U-shaped or C-shaped sections which are slidable into one another.
- the two individual sections forming the side struts 14, 15 may be fixed or detachably connected to the respective side wall 111 of the corner post 11.
- a firm connection of the two individual sections of the side struts 14, 15 on the side walls 111 of the corner posts 11 may be given by a riveting or welding.
- a releasable connection can be given by a screw or plugging or the like.
- the longitudinal side struts 14 are fixedly connected to the side wall 111 of the respective corner post 11, whereas the shorter and less solid formed transverse side struts 15 are detachably connected to the respective corner post 11. In this way, the stacking device 10, when not in use can be disassembled and takes up little transport volume.
- a second pallet 1 ' can be placed, or even a unit of a second pallet 1' and another stacking device 10. Such an arrangement is in Fig. 2 shown.
- the inclination of the side walls of the receiving cups 121 facilitates the placement of the upper second pallet 1 'or the unit of the second pallet 1' and the other stacking device 10, while a lateral slippage of the second pallet 1 'is prevented.
- the supports 12 have a triangular profile and are guided vertically adjustable in the corner posts 11. To guide are at the in Fig. 1 paragraphs formed in the side walls 111 formed, preferably punched, so that the supports 12 are guided in the angular range of the corner posts 11 and the side walls 111 abut in its outer region on the pallet 1.
- Each support 12 is coupled to a support member 13 which rests on the top of the pallet 1.
- the support element 13 is formed in the example shown as a foot which rests on the pallet 1. In this way, weight forces of the upper second pallet or all other pallets stacked thereon are transmitted directly via the extendable support 12 and the support element 13 to the lower, first pallet 1.
- the corner posts 11 themselves do not need to absorb the weight forces, but serve to guide the supports 12 and the absorption of lateral forces.
- a row of holes 122 is formed with vertically spaced holes into which the support member 13 engages.
- the connection between the support 12 and the support element 13 is adjustable, so that it can be adjusted as far as the supports 12 protrude from the corner post 11. It can be varied as needed, the stack height, so the distance between two stacked pallets 1 and 1 '.
- the corner posts 11 may be closed at a lower end 112 with, for example, triangular shaped bottom plates.
- the pallet 1 is embraced in the corner not only outside, but also from above and below, whereby the stacking device 10 is more securely connected to the pallet.
- FIG. 3 shows the stacking device 10 according to Fig. 1 together with a pallet 1 of different dimensions than the pallet 1 of Fig. 1 ,
- the same reference numerals in this figure denote the same or equivalent elements as in FIG Fig. 1 ,
- pallet 1 has a different ratio of the length of the transverse or longitudinal side than in Fig. 1 shown.
- the lateral side being looked at is longer than the long side.
- the pallet 1 is the Fig. 3 a so-called "half euro pallet", which is also used in the industry.
- the stacking device 10 can also be adapted to this pallet size.
- Fig. 4 shows a second embodiment of an according to the application stacking device 10 in a second embodiment.
- the stacking device is in turn placed on a (Euro) pallet 10.
- Euro (Euro) pallet 10.
- the same reference numerals in this as the following figure identify the same or equivalent elements as in the first embodiment.
- the stacking device 10 corresponds to that described in the previous figures.
- the accompanying description is hereby incorporated by reference.
- the corner posts 11 are slightly offset inwards. They do not lie with their side walls 111 directly outside on the corners of the pallet 1, but have only at its lower end on the side walls 111 patch tabs 113 which abut laterally at the corners of the pallet 1.
- the tabs 113 fix the stacking device 10 with respect to its lateral position. They are not necessarily enough for this purpose to the bottom of the pallet 1.
- the stacking device 10 projects only slightly to the sides - namely with the material thickness of the tabs 113 of a few millimeters and the edge of the receiving trays 112 beyond the pallet 1 addition, whereby the pallet 1 with the stacking device 10 or even more stacked pallets 1 occupy approximately the same footprint as a pallet 1 without stacking device 10th
- Fig. 4 In the example of Fig. 4 are the reference numerals 141 and 151, the previously mentioned fixing means for determining the length of the side struts 14 and 15, respectively.
- the stacking device 10 can be folded flat when not needed and transported to save space.
- the side strut 14 is pivotally mounted at its lower edge about a horizontal axis to the corner posts 11 in a respective pivot bearing 143.
- the pivot bearings 143 have e.g. a pin with a thickening at the free end to be loaded on train.
- a latch 144 is provided on each side to fix the side strut 14 in the illustrated closed position.
- the side strut 14 can be folded down. Storage goods can thus be viewed and possibly taken to the side of the pallet 1.

Description
Die Erfindung betrifft eine Stapelvorrichtung für Paletten, um eine zweite Palette auf einer ersten Palette stapeln zu können.The invention relates to a stacking device for pallets in order to be able to stack a second pallet on a first pallet.
Paletten werden im Güterverkehr zum Transport und auch zur Lagerung von Waren aller Art als Einmal-Paletten oder auch im Tauschverfahren genutzt. In einer häufig benutzten Variante sind die Paletten aus Holz gefertigt mit zwei oder drei in einer Richtung parallel verlaufenden und auf dem Boden aufliegenden Trägern, auf denen Querleisten und Deckbretter angeordnet sind. Die Deckbretter stellen eine Ladefläche bereit, auf die eine Lager- bzw. Transportgut, z.B. Kartons, gestellt werden können. Zur Sicherung der Ladung werden in der Regel Bänder oder Folien eingesetzt.Pallets are used in freight transport for the transport and storage of goods of all kinds as disposable pallets or in exchange. In a frequently used variant, the pallets are made of wood with two or three in one direction parallel and resting on the ground straps on which transverse strips and cover boards are arranged. The cover boards provide a loading area onto which a storage or transport goods, e.g. Cartons, can be provided. As a rule, tapes or foils are used to secure the load.
Die Anordnung der auf dem Boden aufliegenden Träger ermöglicht ein Unterfahren mit der Gabel eines Flurförderfahrzeugs, beispielsweise eines Hubwagens oder eines Gabelstaplers. Neben der beschriebenen Konstruktion aus Holzbalkenstücken und Leisten sind auch Versionen aus einem geprägten oder gespritzten Kunststoff- oder Kunststoff-Komposit-Material in Verwendung. Mit der sogenannten "Europalette" hat sich eine genormte Palettengröße etabliert, es sind jedoch regelmäßig Paletten in unterschiedlichen Größen im Einsatz.The arrangement of the resting on the ground carrier allows underrun with the fork of a material handling vehicle, such as a lift truck or a forklift. In addition to the described construction of wooden beam pieces and strips versions of an embossed or molded plastic or plastic composite material in use. The so-called "Euro pallet" has established a standardized pallet size, but pallets of different sizes are regularly in use.
Paletten sind vielseitig einsetzbar und kostengünstig. Im Vergleich zu den allerdings sehr viel teureren und aufwändigeren Gitterboxen ist bei beladenen Paletten jedoch die fehlende Stapelbarkeit nachteilig.Pallets are versatile and inexpensive. In comparison to the much more expensive and complex lattice boxes, however, the lack of stackability is disadvantageous for loaded pallets.
Bekannt sind Aufsatzrahmen aus Holz, die Seitenwände für die Paletten bieten, so dass kleinere Kartons etc. eingestellt werden können, ohne Bänder oder Folie zum Sichern dieser Kartons zu verwenden. Die Seitenwände sind eigentlich nicht dazu gedacht, eine zweite Palette auf eine erste, die mit solchen Seitenwänden ausgestattet ist, zu stapeln. In der Praxis wird das jedoch durchaus so praktiziert. Allerdings ist die aufgesetzte zweite Palette nicht seitlich fixiert, so dass keine horizontal wirkenden Kräfte an die untere erste Palette weitergeleitet werden können. Das Stapeln von Paletten auf die aufgesetzten Seitenwände mag daher für Lagerzwecke verwendbar sein, ist für Transportzwecke jedoch ungeeignet, da beim Transport beim Beschleunigen, Bremsen und bei Kurvenfahrten derartige Seitenkräfte auftreten und aufgefangen werden müssen, um die Ladung gegen ein Verrutschen oder Umstürzen zu sichern. Zudem kann eine gegebene Seitenwand für nur eine Palettengröße eingesetzt werden.Known are wooden attachment frames that provide side panels for the pallets so that smaller boxes etc. can be set without using straps or foil to secure these boxes. The side walls are not actually intended to stack a second pallet onto a first one equipped with such side walls. In practice, however, this is quite the practice. However, the patch second pallet is not fixed laterally, so that no horizontally acting forces can be forwarded to the lower first pallet. The stacking of pallets on the mounted side walls may therefore be suitable for storage purposes, but is unsuitable for transport purposes, since during transport during acceleration, braking and cornering such lateral forces occur and must be collected to secure the load against slipping or overturning. In addition, a given sidewall can be used for only one pallet size.
Eine weitere bekannte Möglichkeit zum Stapeln von Paletten bieten Abstandshalter aus gebogenem Blechmaterial, die im Zubehörhandel erhältlich sind. Diese werden an den vier Ecken auf die erste untere Palette aufgesetzt, so dass eine zweite Palette oben auf die Abstandshalter abgesetzt werden kann. Auch diese Lösung ist nur für die Lagerung, nicht aber für Transportzwecke geeignet. Ein Vorteil dieser Lösung ist, dass sie für verschiedene Palettengrößen verwendet werden kann.Another known way of stacking pallets is to provide bent sheet metal spacers available from the aftermarket. These are placed at the four corners on the first lower pallet, so that a second pallet can be placed on top of the spacers. This solution is only suitable for storage, but not for transport purposes. An advantage of this solution is that it can be used for different pallet sizes.
Die Druckschrift
Es ist eine Aufgabe der vorliegenden Erfindung, eine Stapelvorrichtung für Paletten zu schaffen, mit der ein gesichertes Stapeln nicht nur zu Lagerungszwecken, sondern auch während eines Transports mit Flurförderzeugen oder Transportfahrzeugen der Logistik möglich ist, wobei Transportkapazitäten bestmöglich ausgenutzt werden können.It is an object of the present invention to provide a stacking device for pallets, with the secure stacking not only for storage purposes, but also during transport with trucks or transport vehicles logistics is possible, with transport capacities can be used as well as possible.
Eine erfindungsgemäße Stapelvorrichtung der eingangs genannten Art zeichnet sich durch vier u-förmige profilierte Eckpfosten aus, wobei Abschnitte der Eckpfosten in jeweils einem Eckbereich der ersten Palette an Außenseiten der ersten Palette anliegen können. Jeweils zwei der benachbarten Eckpfosten sind über eine Seitenstrebe miteinander verbunden. Jeder Eckpfosten weist zudem ein Abstützelement auf, das sich im jeweiligen Eckbereich auf einer Oberseite der Palette abstützt. In oder an jedem Eckpfosten ist eine nach oben ausfahrbare Stütze geführt, wobei an einem oberen, freien Ende der Stütze eine Aufnahme für jeweils eine Ecke einer zweiten Palette angebracht ist. Die nach oben ausfahrbare Stütze ist bevorzugt in verschiedenen Positionen arretierbar. Auf diese Weise kann die Stapelhöhe, d.h. der Abstand zwischen der ersten und der zweiten Palette, nach Bedarf eingestellt werden. So können Transportkapazitäten optimal ausgenutzt werden. Wird die Stapelvorrichtung in einer Lagerhaltung eingesetzt, kann die Stapelhöhe auch bewusst erhöht werden, um einen Freiraum oberhalb des Lagerguts der ersten Palette zu schaffen, der einen leichteren Zugang zum Lagergut ermöglicht. Zur Arretierung kann eine Lochleiste vorgesehen sein, in die ein Bolzen oder eine Schraube durchgesteckt wird, um die Stütze in geeigneter Höhe im Eckpfosten festzulegen.A stacking device according to the invention of the type mentioned above is characterized by four U-shaped profiled corner posts, wherein sections of the corner posts can rest in each case in a corner region of the first pallet on outer sides of the first pallet. Two of the adjacent corner posts are connected to each other via a side strut. Each corner post also has a support element which is supported in the respective corner region on an upper side of the pallet. In or on each corner post an upwardly extendable support is guided, wherein at an upper, free end of the support a receptacle is mounted for each corner of a second pallet. The Upwardly extendable support is preferably lockable in different positions. In this way, the stack height, ie the distance between the first and the second pallet, can be adjusted as needed. Thus, transport capacities can be optimally utilized. If the stacking device used in a storage, the stack height can also be increased deliberately to create a free space above the stored goods of the first range, which allows easier access to the stored goods. To lock a perforated strip may be provided, in which a bolt or screw is pushed through to set the support at a suitable height in the corner post.
Dadurch, dass die Eckpfosten die Ecken der unteren ersten Palette außen umgreifen und jeweils benachbarte Eckpfosten über die Seitenstreben miteinander verbunden sind, ist ein die Palette umgebender Rahmen gebildet, der Seitenkräfte und Kippmomente von der oberen, zweiten Palette auf die untere, erste Palette übertragen kann. Die Abstützelemente übertragen die Gewichtskraft oberen, zweiten Palette auf die untere, erste Palette, so dass der gesamte gebildete Palettenstapel durch Anheben der ersten Palette durch einen Stapler oder einen Hubwagen angehoben und z.B. verladen werden kann.Characterized in that the corner posts surround the corners of the lower first pallet on the outside and adjacent corner posts are connected to each other via the side struts, a frame surrounding the pallet is formed, the side forces and tilting moments of the upper, second pallet on the lower, first pallet can transfer , The support members transfer the weight of the upper, second pallet to the lower, first pallet so that the entire pallet stack formed is lifted by lifting the first pallet by a stacker or pallet truck, and e.g. can be loaded.
Das Abstützelement kann fest, insbesondere z.B. durch Schweißen stoffschlüssig mit dem Eckpfosten verbunden sein. In einer weiteren vorteilhaften Ausgestaltung der Stapelvorrichtung ist das Abstützelement gegenüber dem Eckpfosten höhenverstellbar, um die Stapelvorrichtung durch Verändern der Position des Abstützelements an Paletten verschiedener Dicke anpassen zu können.The support element may be fixed, in particular e.g. be joined by welding material fit with the corner posts. In a further advantageous embodiment of the stacking device, the support element is height-adjustable relative to the corner post in order to be able to adapt the stacking device to pallets of different thickness by changing the position of the support element.
In einer weiteren vorteilhaften Ausgestaltung der Stapelvorrichtung ist das höhenverstellbare Abstützelement mit der nach oben ausfahrbaren Stütze verbunden. Auf diese Weise werden Gewichtskräfte der oberen zweiten Palette bzw. aller weiteren darauf gestapelten Paletten unmittelbar über die ausfahrbare Stütze und das Abstützelement auf die untere, erste Palette übertragen. Die Eckpfosten selbst brauchen die Gewichtskräfte dann gar nicht aufnehmen, sondern dienen der Führung der Stützen und der Aufnahme von Seitenkräften. Eine unvermeidbare Reibung zwischen den Eckpfosten und den Stützen sowie den Eckpfosten und der ersten Palette verhindert dabei ein Verrutschen der Eckpfosten beim Anheben der ersten Palette. Die Verbindung zwischen Stütze und Abstützelement kann wiederum jeweils verstellbar sein, z.B. mittels einer Lochreihe in der Stütze, um die Stapelhöhe variieren zu können.In a further advantageous embodiment of the stacking device, the height-adjustable support element is connected to the upwardly extendable support. In this way, weight forces of the upper second pallet or all other pallets stacked thereon are transmitted directly via the extendable support and the support element to the lower, first pallet. The corner posts themselves do not need to absorb the weight forces, but serve to guide the supports and the absorption of lateral forces. An inevitable friction between the corner posts and the columns and the corner posts and the first pallet prevents slipping of the corner posts when lifting the first pallet. The connection between the support and support element can in turn be adjustable in each case, for example by means of a row of holes in the support in order to vary the stack height.
In einer weiteren vorteilhaften Ausgestaltung sind zumindest zwei gegenüberliegende Seitenstreben teleskopierbar, wodurch die Stapelvorrichtung für Paletten unterschiedlicher Größe einsetzbar ist. Bevorzugt umfassen die teleskopierbaren Seitenstreben zwei ineinander greifende und zueinander verschiebbare Abschnitte (Teilstücke). Diese können z.B. durch Schienen mit einem u- oder c-förmigen und ineinander greifenden Profil gebildet sein. Es können wiederum Lochreihen, gegebenenfalls mit Langlöchern vorgesehen sein, um die teleskopierbaren Seitenstreben in geeigneten Längen zu fixieren. Auch andere rastende oder klemmende Mittel, um die teleskopierbaren Seitenstreben in ihrer Länge zu fixieren, können eingesetzt werden.In a further advantageous embodiment, at least two opposing side struts are telescopic, whereby the stacking device can be used for pallets of different sizes. Preferably, the telescopic side struts comprise two intermeshing and mutually displaceable sections (sections). These may e.g. be formed by rails with a u- or c-shaped and interlocking profile. It can turn rows of holes, possibly provided with slots to fix the telescopic side struts in appropriate lengths. Other locking or clamping means to fix the telescopic side struts in their length, can be used.
In einer weiteren vorteilhaften Ausgestaltung der Stapelvorrichtung ist zumindest eine der Seitenstreben an beiden Enden über jeweils ein Schwenklager um eine horizontale Achse verschwenkbar an den zugeordneten Eckpfosten gelagert ist. Auf diese Weise kann die Seitenstrebe weggeklappt, insbesondere heruntergeklappt werden, um auch bei gestapelten Palette deren Lagergut von der Seite einsehen und ggf. auch entnehmen zu können bzw. Lagergut hinzufügen zu können.In a further advantageous embodiment of the stacking device at least one of the side struts is pivotally mounted at both ends via a respective pivot bearing about a horizontal axis to the associated corner post. In this way, the side strut can be folded away, in particular folded down, to see even with stacked pallet whose stored goods from the side and possibly also to remove or to be able to add stored goods.
Weiter bevorzugt können die Seitenstreben mit den Seitenwangen der Eckpfosten fest verbunden sein oder auch abnehmbar gestaltet sein. Besonders vorteilhaft ist es, wenn die in eine Richtung der Paletten verlaufenden Seitenstreben fest an den beiden jeweiligen Eckpfosten verbunden sind, wohingegen die quer dazu verlaufenden Seitenstreben lösbar, beispielsweise über eine Schraub- oder gegebenenfalls gesicherte Einhakverbindung lösbar sind, so dass diese Seitenstreben abgenommen werden können. Für Transportzwecke lässt sich die Stapelvorrichtung dann in zwei längliche Einheiten (jeweils zwei über die fest montierten Seitenstrebe verbundene Eckpfosten) und zwei separate Seitenstreben trennen. Diese können flach aufeinander liegend transportiert werden, ohne dass sie ein großes Transportvolumen einnehmen.More preferably, the side struts can be firmly connected to the side cheeks of the corner posts or designed to be removable. It is particularly advantageous if the side struts extending in one direction of the pallets are firmly connected to the two respective corner posts, whereas the lateral struts extending transversely thereto are detachably detachable, for example by means of a screwed or optionally secured hooking connection, so that these side struts can be removed , For transport purposes, the stacker can then be separated into two elongated units (two each connected via the fixed side strut corner posts) and two separate side struts. These can be transported flat on top of each other without taking up a large transport volume.
Alternativ oder zusätzlich können alle oder ein Teil der Seitenstreben z.B. mittels Scharnieren an den Eckpfosten befestigt sein, so dass sie horizontal schwenkbar sind. Eine nicht benutzte Stapelvorrichtung, die nicht um eine Palette herum angeordnet ist, kann durch die Scharniere zu Transportzwecken flach zusammengelegt werden.Alternatively or additionally, all or part of the side struts may be e.g. be attached by hinges to the corner posts, so that they are horizontally pivotable. An unused stacking device, which is not arranged around a pallet, can be folded flat by the hinges for transport purposes.
In einer weiteren vorteilhaften Ausgestaltung der Stapelvorrichtung sind die Eckpfosten und/oder die Stützen und/oder die Seitenstreben bzw. die Teilstücke teleskopierbarer Seitenstreben ganz oder teilweise aus einem Metallblech gefertigt, insbesondere in einem Stanz- und Biegeverfahren.In a further advantageous embodiment of the stacking device, the corner posts and / or the supports and / or the side struts or the sections telescopic side struts wholly or partly made of a metal sheet, in particular in a stamping and bending process.

Die Palette 1, die hier beispielhaft eine Europalette ist und in genormten Abmessungen aus Holzklötzen und Holzbrettern gefertigt ist, weist zwei Außenträger 2 und einen Mittelträger 3 auf. Diese sind so angeordnet, dass in Längsrichtung der Palette 1 eine Gabel eines Hubwagens oder eines Gabelstaplers eingeschoben werden kann, um die Palette 1 anzuheben und verladen zu können.The
Außenträger 2 und der Mittelträger 3 sind über Querleisten 4 miteinander verbunden, auf denen wiederum Deckbretter 5 befestigt sind, die eine Ladefläche der Palette 1 bilden.
Die Stapelvorrichtung 10 weist vier Eckpfosten 11 auf, die bevorzugt aus gekantetem Blechmaterial gefertigt sind und jeweils zwei im Wesentlichen rechtwinklig zueinander stehende Seitenwangen 111 aufweisen. Die Eckpfosten 11 liegen mit den Seitenwangen 111 außen an der Palette 1 an, konkret im Bereich von Eckklötzen der Außenträger 2.The stacking
Jeweils benachbarte Eckpfosten 11 sind über Seitenstreben 14, 15 miteinander verbunden. In Längsrichtung der Palette 1 sind längere und auch in ihrem Querschnitt breitere Seitenstreben 14 eingesetzt und entlang der Querseite der Palette 1 kürzere und in ihrem Querschnitt kleinere Seitenstreben 15.Each adjacent corner posts 11 are connected by side struts 14, 15 with each other. In the longitudinal direction of the
Die Seitenstreben 14, 15 sind vorteilhaft jeweils teleskopierbar, z.B. indem zwei ineinander schiebbare Abschnitte (Teilstücke) eingesetzt werden. Die Seitenstreben 14, 15 können beispielsweise aus zwei u-förmigen oder c-förmigen Teilstücken aufgebaut sein, die ineinander schiebbar sind.The side struts 14, 15 are each advantageously telescopic, e.g. by inserting two telescoping sections (sections). The side struts 14, 15 may for example be constructed of two U-shaped or C-shaped sections which are slidable into one another.
Die beiden einzelnen Teilstücke, die die Seitenstreben 14, 15 bilden, können fest oder lösbar mit der jeweiligen Seitenwange 111 des Eckpfostens 11 verbunden sein. Eine feste Verbindung der beiden einzelnen Teilstücke der Seitenstreben 14, 15 an den Seitenwangen 111 der Eckpfosten 11 kann durch eine Vernietung oder Verschweißung gegeben sein. Eine lösbare Verbindung kann durch eine Verschraubung oder ein Einstecken oder ähnliches gegeben sein.The two individual sections forming the side struts 14, 15 may be fixed or detachably connected to the
In einer bevorzugten Ausgestaltung sind die längs verlaufenden Seitenstreben 14 fest mit der Seitenwange 111 des jeweiligen Eckpfostens 11 verbunden, wohingegen die kürzeren und weniger solide ausgebildeten quer verlaufenden Seitenstreben 15 lösbar mit dem jeweiligen Eckpfosten 11 verbunden sind. Auf diese Weise kann die Stapelvorrichtung 10, wenn sie nicht in Verwendung ist zerlegt werden und nimmt wenig Transportvolumen ein.In a preferred embodiment, the longitudinal side struts 14 are fixedly connected to the
Auch ist es denkbar, jeweils zumindest eines der beiden an einen Eckpfosten 11 angrenzendes Teilstücke der Seitenstreben 14, 15 mittels eines Scharniers am Eckpfosten 11 zu befestigen. Die Stapelvorrichtung 10 kann dann ebenfalls flach zusammengelegt werden, wenn sie nicht benötigt wird.It is also conceivable to attach in each case at least one of the two sections of the side struts 14, 15 adjacent to a
Die teleskopierbaren Seitenstreben 14, 15 sind bevorzugt mit Rast- oder Fixiermitteln (vgl. Fixiermittel 141, 151 bei dem Ausführungsbeispiel der
Auf die Aufnahmeschalen 121 kann eine zweite Palette 1' aufgelegt werden, oder auch eine Einheit aus einer zweiten Palette 1' und einer weiteren Stapelvorrichtung 10. Eine solche Anordnung ist in
Die Schrägstellung der Seitenwände der Aufnahmeschalen 121 erleichtert das Aufsetzen der oberen zweiten Palette 1' oder der Einheit aus der zweiten Palette 1' und der weiteren Stapelvorrichtung 10, wobei gleichzeitig ein seitliches Verrutschen der zweiten Palette 1' verhindert wird.The inclination of the side walls of the receiving
Die Stützen 12 weisen ein dreieckiges Profil auf und sind in den Eckpfosten 11 höhenverstellbar geführt. Zur Führung sind bei dem in
Jede Stütze 12 ist mit einem Abstützelement 13 gekoppelt, das auf der Oberseite der Palette 1 aufliegt. Das Abstützelement 13 ist im dargestellten Beispiel wie ein Fuß ausgebildet, der auf der Palette 1 aufsitzt. Auf diese Weise werden Gewichtskräfte der oberen zweiten Palette bzw. aller weiteren darauf gestapelten Paletten unmittelbar über die ausfahrbare Stütze 12 und das Abstützelement 13 auf die untere, erste Palette 1 übertragen. Die Eckpfosten 11 selbst brauchen die Gewichtskräfte gar nicht aufnehmen, sondern dienen der Führung der Stützen 12 und der Aufnahme von Seitenkräften.Each
In der Stütze 12 ist eine Lochreihe 122 mit vertikal beabstandeten Löchern ausgebildet, in die das Abstützelement 13 eingreift. Auf diese Weise ist die Verbindung zwischen der Stütze 12 und dem Abstützelement 13 verstellbar, so dass eingestellt werden kann, wie weit die Stützen 12 aus dem Eckpfosten 11 herausragen. Es kann so die Stapelhöhe, also der Abstand zwischen zwei gestapelten Paletten 1 und 1', nach Bedarf variiert werden.In the
In einer alternativen Ausgestaltung der Stapelvorrichtung kann sowohl die Stütze, als auch das Abstützelement am Eckpfosten, ggf. jeweils höhenverstellbar, befestigt sein.In an alternative embodiment of the stacking device, both the support, as well as the support element on the corner posts, if necessary, each height adjustable, be attached.
In einer weiteren alternativen Ausgestaltung der Stapelvorrichtung können die Eckpfosten 11 an einem unteren Ende 112 mit beispielsweise dreieckig geformten Bodenplatten verschlossen sein. So wird die Palette 1 im Eckbereich nicht nur außen, sondern auch von oben und unten umgriffen, wodurch die Stapelvorrichtung 10 noch sicherer mit der Palette verbunden ist.In a further alternative embodiment of the stacking device, the corner posts 11 may be closed at a
Die in
In ihrem Grundaufbau entspricht die Stapelvorrichtung 10 der in den vorherigen Figuren beschriebenen. Auf die zugehörige Beschreibung wird hiermit verwiesen.In its basic structure, the stacking
Im Unterschied zum ersten Ausführungsbeispiel sind vorliegend die Eckpfosten 11 leicht nach innen versetzt. Sie liegen nicht mit ihren Seitenwangen 111 direkt außen an den Ecken der Palette 1 an, sondern weisen nur an ihrem unteren Ende auf die Seitenwangen 111 aufgesetzte Laschen 113 auf, die seitlich an den Ecken der Palette 1 anliegen. Die Laschen 113 fixieren die Stapelvorrichtung 10 bezüglich ihrer seitlichen Position. Sie reichen zu diesem Zweck nicht zwingend bis zum unteren Rand der Palette 1.In contrast to the first embodiment, in the present case, the corner posts 11 are slightly offset inwards. They do not lie with their
Durch die derart gekröpfte Bauweise der Eckpfosten 11 ragt die Stapelvorrichtung 10 zu den Seiten nur geringfügig - nämlich mit der Materialstärke der Laschen 113 von wenigen Millimetern und dem Rand der Aufnahmeschalen 112 über die Palette 1 hinaus, wodurch die Palette 1 mit der Stapelvorrichtung 10 bzw. auch mehrere gestapelte Paletten 1 annähernd die gleiche Grundfläche einnehmen wie eine Palette 1 ohne Stapelvorrichtung 10.By so cranked construction of the corner posts 11, the stacking
Bei dem Beispiel der
Weiterhin sind bei diesem Ausführungsbeispiel die längs und quer verlaufenden Seitenstreben 14, 15 mit Scharnieren 142 bzw. 152 an den Eckpfosten 11 anmontiert. Dadurch kann die Stapelvorrichtung 10 im nicht benötigten Zustand flach zusammengelegt werden und platzsparend transportiert werden.Furthermore, in this embodiment, the longitudinal and transverse side struts 14, 15 with
Ein weiterer Unterschied zu dem ersten Ausführungsbeispiel besteht darin, dass zumindest eine der Seitenstreben 14, 15, vorliegend beispielhaft die in der Figur vordere längsseitig verlaufende Seitenstrebe 14, herunter klappbar ist, um auch bei gestapelten Paletten 1 an deren Lager- bzw. Transportgut zu gelangen. Zu diesem Zweck ist die Seitenstrebe 14 an ihrer unteren Kante um eine horizontale Achse schwenkbar an den Eckpfosten 11 in jeweils einem Schwenklager 143 gelagert. Die Schwenklager 143 weisen z.B. einen Zapfen mit einer Verdickung am freien Ende auf, um auch auf Zug belastbar zu sein. Im Bereich der oberen Kante ist auf jeder Seite ein Riegel 144 vorgesehen, um die Seitenstrebe 14 in der dargestellten geschlossenen Position festzulegen.Another difference from the first embodiment is that at least one of the side struts 14, 15, in the present example, the front side extending in the
