Definitions
- Inferior wooden pallets usually also have relatively large deviations of their geometry from the specified dimensions in standards, which can also make disturbing noticeable.
- Plastic pallets with runners which are not equipped with special equipment, such as Steel reinforcement, are equipped, also can not be used in automated storage systems in the rule, since the caused essentially by creep of the plastic material deformation can lead to malfunction.
- auxiliary carriers which additionally support the pallets on the spanned length, the problem of deformation can be solved.
- plastic pallets with skids are estimated to be fundamentally more reliable than wooden pallets due to their geometric integrity and dimensional accuracy. Occasionally Therefore, high-quality plastic pallets are used in automated high-bay warehouses. But these expensive pallets are also subject to considerable wear.
- the invention is based on the object to avoid the malfunction caused by wooden pallets in automated storage systems, and to allow the use of damaged pallets and the storage of half or quarter pallets.
- nestable transport pallets which usually have no skids to be made possible in storage systems of the type mentioned.
- an additional shuttle pallet eliminates "inadequacies" of the pallets to be stored.
- transport pallets made of wood whose dimensions no longer comply with the prescribed standard dimensions or in which smaller parts are chipped off, are placed on the shuttle pallet according to the invention.
- the transport pallet with the goods stored on it becomes then moved together with the shuttle pallet in the automated storage system, for example by roller conveyors, chain conveyors, stacker cranes and other more, and finally stored in a storage bin and removed again when needed.
- Only the shuttle pallet according to the invention has contact with the roller conveyors, chain conveyors, stacker cranes and the storage bins of the storage system, the transport pallet has no direct contact with the storage system, so that inadequacies of the transport pallets, not affect the storage system.
- inadequacies of the transport pallets can be eliminated and the shuttle pallet according to the invention can be fully optimized to the requirements within the storage system.
- the feet of the load receiving bridges are inventively designed so that the side members can move to each other in the XZ plane, wherein the movement is impressed by unevenness of the roller conveyor. Therefore, the feet are advantageous as resilient joints, in particular as a leaf spring-like joints executed, which allow small movements.
- the side members are made in particular of a pipe section of structural steel or aluminum and more preferably of a tube with annular cross-section with or without flattening.
- the contact between the roller conveyors and chain conveyors can be limited to the longitudinal beams of structural steel or a material with a smaller modulus of elasticity.
- These side rails are because of their Materials are naturally very wear-resistant and can therefore be used for a long time without significant wear.
- Other longitudinal members according to the invention consist of profiles with rigid cross-section, which have on the tread a larger contact area than a tube with annular cross-section to the conveyor (roller conveyors, etc.) to reduce the surface pressure and the resulting stresses.
- this may be, for example, a flattened to the tread, but otherwise substantially circular tube.
- this can also be achieved by other profiles with rigid cross-section, which have a larger contact area to the conveyor on the tread.
- the surface pressure (Hertzian pressure) is reduced between longitudinal members and, for example, the rollers of a roller conveyor and thus reduces the stresses occurring thereby.
- the Hertzian pressure can be further reduced if a material with a small modulus of elasticity is used as steel. This can be aluminum, for example.
- feet are formed on each load-bearing bridge.
- the longitudinal members are connected by a snap connection or a clip connection with the load receptacles for bridges. If the connection is made detachable, it is also possible to exchange individual longitudinal members or even individual load-bearing bridges in the event of damage, so that the cost-effectiveness of the shuttle pallets according to the invention is further improved.
- the load receiving bridges are formed rigid in a direction orthogonal to the longitudinal members.
- the load receiving bridges are provided between two load-receiving bridges in the direction of the longitudinal members extending spacers. This ensures that the load-carrying bridges can not move relative to each other. As a result, the dimensions of the shuttle pallet according to the invention do not change even with heavy and multiple stress and it is a trouble-free operation in the automated storage system guaranteed.
- the spacers and the load receiving bridges may be integrally formed.
- the longitudinal beams which preferably consist of a tube with annular cross-section consclipsen.
- the load-bearing bridges may be preferred made of plastic, in particular HDPE and / or recycled plastic. As a result, even complicated geometries and a weight-optimized design can be easily realized.
- the shuttle pallet according to the invention can also be raised and transported with rack feeders, forklifts and others, it is provided that two recesses extending in the longitudinal direction are present between the longitudinal carriers on the underside of the shuttle pallet.
- the distance between the center axes of the recesses is between 340 mm and 400 mm, and particularly preferably 370 mm.
- the height of the recess is advantageously greater than 85 mm and the width of the recesses is greater than 160 mm.
- the dimensions of the shuttle pallet in particular its length and width correspond to at least the standard dimensions of so-called transport pallets, in particular Euro pallets.
- the invention is provided in a further advantageous embodiment at an upper side of the shuttle pallet Form load receiving points, wherein the distances of the load receiving points from one another correspond to the distances of the feet of a standard range, in particular a euro pallet.
- these load-receiving points are arranged vertically above the feet of the shuttle pallet. As a result, the bending stresses due to weight forces between transport pallet and shuttle pallet are minimized.
- the shuttle pallet can be provided in the region of the load receiving points, in particular by shells made of a wear-resistant material, such as sheet steel, in a further advantageous embodiment. to reinforce.
- FIG. 1 is a first embodiment of a shuttle pallet 1 according to the invention with a total of three load-bearing bridges 3 shown in an isometric view.
- the load-bearing bridges 3 are designed rigid in the direction of a Y-axis and have a plurality of ribs 5, which extend substantially in the direction of the Y-axis.
- the ribs 5, which have not all been provided with reference numerals for reasons of clarity, ensure the desired flexural rigidity in the direction of the Y-axis, while maintaining a low dead weight.
- the ribs 5 are reinforced by transverse ribs 9.
- load receiving points 7 which correspond to the load loading points conventional transport pallets in terms of arrangement and distance. If, for example, a Euro pallet (not shown) is placed as a typical representative of a transport pallet on the shuttle pallet according to the invention, the feet of the Euro pallet in the area of the load receiving points 7 on the shuttle pallet 1 and the weight of the transport pallet or the on it goods is introduced via the load receiving points 7 in the shuttle pallet 1.
- an edge 11 of the shuttle pallet 1 is slightly raised relative to the inner region, so that a remote on the shuttle pallet transport pallet (not shown) is secured laterally and in all directions against slipping.
- spacers 15 are provided between the arranged in the direction of an X-axis, corresponding to the longitudinal axis of the shuttle pallet 1, 13 feet spacers 15 are provided, which ensure that the load-bearing bridges 3 are fixed relative to each other in the direction of the X-axis.
- the spacers 15 and the load receiving bridges 3 are integrally formed.
- the load receiving bridges 3 are designed so that they can be well undercut by the fork of a stacker crane (not shown). For this purpose, 3 recesses 18 are formed between the feet 13 of a load-receiving bridge.
- the storage and retrieval unit moves its fork down the shuttle pallet 1 and sets the loaded shuttle pallet 1 in the parking space.
- FIG. 2 are three load-carrying bridges 3 shown without spacers. It is clear that the shuttle pallet 1 according to the invention is torsionally soft, so that the shuttle pallet 1 can twist when it is parked, for example, on an uneven shelf, or via a roller conveyor, in which not all rollers are arranged exactly in one plane. Even with the spacers 15, the shuttle pallet 1 is torsionally soft.
- 3 snap connections 17 are formed with a circular segment-shaped cross section in the feet 13 of the load receiving bridges. These snap connections 17 extend in the direction of the X-axis and serve to receive a longitudinal carrier (not shown), which preferably consists of a steel tube with a circular cross-section. At the ends of the shuttle pallet 1, the snap connections 17 are closed, so that the side member can not move in the direction of the X axis relative to the load receiving bridges 3.
- FIG. 3a is the shuttle pallet 1 according to FIG. 1 isometric shown from below. It is clear that the snap connections 17 extend over the entire length of the shuttle pallet 1 and are also formed in the spacers 15.
- longitudinal members 19 are introduced into the snap connection 17. Thereby, a positive and simultaneously releasable connection between the side rails 19 and the feet 13 and the spacers 15 of the shuttle pallet 1 is produced.
- the longitudinal members 19 may consist of commercially available steel tube with an annular cross-section and are firstly cost-effective, Second, wear-resistant and, thirdly, rigid. As a result, the shuttle pallet 1 according to the invention can be loaded with large weights without the shuttle pallet sagging even in the case of long dwell times in a storage location.
- FIG. 4 is a cross section through a foot 13 with inserted longitudinal member 19 is shown.
- the longitudinal member 19 as in the other embodiments, also formed as a pipe with an annular cutout.
- the snap connection 17 consists of a circular segment-shaped portion which comprises more than 180 ° and is open at the bottom. This makes it possible to introduce the longitudinal member 19 in the snap device 17 from below. In this case, the snap device 17 or the foot 13 is expanded laterally and springs back to its original position, as soon as the longitudinal member 19 in the in FIG. 4 shown position within the foot 13 has arrived.
- FIG. 5 is shown part of a shuttle pallet according to the invention, as it slides over a roller conveyor.
- a side view is shown in the right part of the FIG. 5 . It is clear that the longitudinal members 19 are in direct contact with the rollers 21 of the roller conveyor. This greatly reduces the wear on the shuttle pallet.
- one of the longitudinal members 19 should be worn or damaged by frequent use, it can be replaced without tools and in the shortest possible time on site.
- FIG. 6 a further embodiment of a shuttle pallet according to the invention.
- the shuttle pallet is located on two spars 23 of a high-bay warehouse.
- the distance between the spars 23 to each other corresponds to the distance that such spars have 23 in conventional high-bay warehouses and is naturally tuned to the length of the Euro pallets or the shuttle range.
- reinforcements 25 are provided at the load receiving points, which prevent the wear of the shuttle pallets in this area. These reinforcements may be formed as shells 25 or metal strips. Again, not all shells 25 are provided with reference numerals for reasons of clarity.
- the shuttle-pallet according to the invention does not bend even if it rests for a long time and loaded with high weight on the spars 23. This makes it possible to store plastic pallets or nestable plastic pallets in a high-bay warehouse, which bend without the additional reinforcement by the longitudinal members 19 according to the invention over time under the load and thereby cause disturbances in the high-bay warehouse.
- FIG. 7 a shuttle pallet according to the invention is shown, with two transport pallets 27.1 and 27.2 loaded in half format. This is readily possible because the load receiving points 7 have a corresponding size.
- a dividing line between the two transport pallets in half format is provided with the reference numeral 29.
- FIG. 8 a plurality of stacked pallets are shown, which are located in a free space of a high-bay warehouse and the lowest rests on two bars 23.
- FIG. 9a a longitudinal member 19 is shown in cross section.
- the annular cross section has a flattening 31.
- the flattening 31 points downwards and thereby increases the contact area between the longitudinal members 19 and the rollers 21 of a roller conveyor (see Fig. 5 )
- FIG. 9b a longitudinal member 19 is shown in cross-section, which does not form part of the claimed invention.
- a longitudinal member 19 is shown in cross section.
- a T-section and a circular section are combined.
- the annular portion serves to attach the longitudinal member 19 to the load receiving bridges 3 while the T-profile 33 forms the contact surface between the longitudinal member 19 and the conveyor and bearing technology (21, 23).

Abstract
Description
In automatisierten Lagersystemen, wie zum Beispiel Hochregallagern, werden Transportpaletten, vorzugsweise Euro-Holzpaletten, durch Rollenbahnen, Kettenförderer, Regalbediengeräte und/oder andere Einrichtungen automatisch befördert, an den gewünschten Lagerplatz des Lagersystem gebracht und bei Bedarf wieder entnommen.In automated storage systems, such as high-bay warehouses, transport pallets, preferably Euro-wooden pallets, automatically conveyed by roller conveyors, chain conveyors, stacker cranes and / or other devices, brought to the desired storage space of the storage system and removed again when needed.
Es ist bekannt, dass die eingesetzten Holzpaletten teilweise zu erheblichen Betriebsstörungen führen; insbesondere durch die Verwendung von schlechtem Holzmaterial bei von außen dem Lagersystem zugeführten Holzpaletten scheinen die Anzahl und der Umfang der Betriebsstörungen zuzunehmen.It is known that the wooden pallets used sometimes lead to considerable disruption of operations; in particular by the use of bad wood material in supplied from the outside of the storage system wooden pallets seem to increase the number and extent of malfunction.
Auch wenn unbeschädigte Holzpaletten in das Lagersystem eingegeben werden, kann die Belastung der Kufen durch die Fördertechnik zu Beschädigungen an den Holzpaletten und damit zu Betriebsstörungen führen.Even if undamaged wooden pallets are entered into the storage system, the loading of the skids by the conveyor system can lead to damage to the wooden pallets and thus to malfunctions.
Minderwertige Holzpaletten weisen in der Regel auch relativ starke Abweichungen ihrer Geometrie von den in Normen festgelegten Sollabmessungen auf, was sich ebenfalls störend bemerkbar machen kann.Inferior wooden pallets usually also have relatively large deviations of their geometry from the specified dimensions in standards, which can also make disturbing noticeable.
Dies führt dazu, dass beispielsweise bei Lagersystemen, welche nur eigene Holzpaletten lagern, besonders teure Holzpaletten aus ausgesuchten Hölzern verwendet werden. Diese Lösung kann bei Lagersystemen, welche überwiegend von Dritten angelieferte Paletten lagern, nicht gewählt werden.As a result, for example, in storage systems which store only their own wooden pallets, particularly expensive wooden pallets made of selected woods are used. This solution can not be selected for storage systems which mainly store pallets delivered by third parties.
Weiter besteht in vielen Lagersystemen die Notwendigkeit, auch Paletten mit kleineren Hauptabmessungen als die Standardpalette (Halbpalette, Viertelpalette) gemischt mit Standardpaletten zu lagern.Further, in many storage systems there is a need to also store pallets with smaller main dimensions than the standard pallet (half pallet, quarter pallet) mixed with standard pallets.
Um diese Probleme zu vermeiden ist aus der
Bekannte automatisierte Lagersysteme erfordern üblicherweise den Einsatz von Paletten mit Kufen, u.a. wegen der verwendeten Rollenbahnen. Die Verwendung von preiswerten nestbaren Paletten, welche in der Regel nicht über Kufen verfügen und deshalb nicht rollenbahngängig sind, ist dadurch verwehrt.Known automated storage systems usually require the use of pallets with runners, i.a. because of the roller conveyors used. The use of inexpensive nestable pallets, which usually do not have skids and therefore are not roller-path, is denied.
Kunststoffpaletten mit Kufen, welche nicht mit besonderen Einrichtungen, wie z.B. Stahlverstärkung, ausgerüstet sind, können in der Regel in automatisierten Lagersystemen auch nicht verwendet werden, da die im wesentlichen durch Kriechen des Kunststoffwerkstoffes hervorgerufene Verformung zu Betriebsstörungen führen kann. Mit aufwändigen Hilfsträgern, welche die Paletten auf der überspannten Länge zusätzlich stützen, kann das Problem der Verformung gelöst werden.Plastic pallets with runners, which are not equipped with special equipment, such as Steel reinforcement, are equipped, also can not be used in automated storage systems in the rule, since the caused essentially by creep of the plastic material deformation can lead to malfunction. With elaborate auxiliary carriers, which additionally support the pallets on the spanned length, the problem of deformation can be solved.
Gleichzeitig werden Kunststoffpaletten mit Kufen dahin gehend eingeschätzt, dass sie durch ihre geometrische Integrität und Maßhaltigkeit grundsätzlich betriebssicherer sind als Holzpaletten. Gelegentlich werden deshalb hochwertige Kunststoffpaletten in automatisierten Hochregallagern eingesetzt. Diese teuren Paletten unterliegen aber auch einem erheblichen Verschleiß.At the same time plastic pallets with skids are estimated to be fundamentally more reliable than wooden pallets due to their geometric integrity and dimensional accuracy. Occasionally Therefore, high-quality plastic pallets are used in automated high-bay warehouses. But these expensive pallets are also subject to considerable wear.

Der Erfindung liegt die Aufgabe zu Grunde, die von Holzpaletten verursachten Betriebsstörungen in automatisierten Lagersystemen zu vermeiden, und die Verwendung auch von beschädigten Paletten und das Einlagern von Halb- oder Viertel-Paletten zu ermöglichen. Darüber hinaus soll auch der Einsatz von nestbaren Transportpaletten, die üblicherweise keine Kufen aufweisen, in Lagersystemen der eingangs genannten Art ermöglicht werden.The invention is based on the object to avoid the malfunction caused by wooden pallets in automated storage systems, and to allow the use of damaged pallets and the storage of half or quarter pallets. In addition, the use of nestable transport pallets, which usually have no skids to be made possible in storage systems of the type mentioned.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Shuttle-Palette für ein Hochregallager, welches für die Lagerung von auf Paletten befindlichen Waren eingerichtete Lagerplätze aufweist, mit den Merkmalen des unabhängigen Anspruchs 1.This object is achieved by a shuttle pallet for a high-bay warehouse, which has arranged for the storage of goods located on pallets storage bins, with the features of independent claim 1.
Durch den Einsatz einer zusätzlichen Shuttle-Palette werden "Unzulänglichkeiten" der einzulagernden Paletten eliminiert. So können beispielsweise Transportpaletten aus Holz, deren Abmessungen nicht mehr den vorgeschriebenen Normmaßen entsprechen oder bei denen kleinere Teile abgesplittert sind, auf die erfindungsgemäße Shuttle-Palette aufgesetzt werden. Die Transportpalette mit den auf ihr gelagerten Waren wird dann zusammen mit der Shuttle-Palette im automatisierten Lagersystem, beispielsweise durch Rollenbänder, Kettenförderer, Regalbediengeräte und anderes mehr bewegt, und schließlich in einem Lagerplatz eingelagert und bei Bedarf wieder entnommen. Dabei hat nur die erfindungsgemäße Shuttle-Palette Kontakt zu den Rollenbahnen, Kettenförderern, Regalbediengeräten und den Lagerplätzen des Lagersystems, die Transportpalette hat keinen direkten Kontakt mit dem Lagersystem, so dass Unzulänglichkeiten der Transportpaletten, das Lagersystem nicht beeinflussen. Infolgedessen können Unzulänglichkeiten der Transportpaletten eliminiert werden und die erfindungsgemäße Shuttle-Palette kann vollständig auf die Anforderungen innerhalb des Lagersystems optimiert werden.The use of an additional shuttle pallet eliminates "inadequacies" of the pallets to be stored. Thus, for example, transport pallets made of wood whose dimensions no longer comply with the prescribed standard dimensions or in which smaller parts are chipped off, are placed on the shuttle pallet according to the invention. The transport pallet with the goods stored on it becomes then moved together with the shuttle pallet in the automated storage system, for example by roller conveyors, chain conveyors, stacker cranes and other more, and finally stored in a storage bin and removed again when needed. Only the shuttle pallet according to the invention has contact with the roller conveyors, chain conveyors, stacker cranes and the storage bins of the storage system, the transport pallet has no direct contact with the storage system, so that inadequacies of the transport pallets, not affect the storage system. As a result, inadequacies of the transport pallets can be eliminated and the shuttle pallet according to the invention can be fully optimized to the requirements within the storage system.
Um ein möglichst verschleißarmes Gleiten der Shuttlepalette auf insbesondere der Rollenbahn zu ermöglichen, sind die Füße der Lastaufnahmebrücken erfindungsgemäß so gestaltet, dass die Längsträger sich zueinander in der XZ-Ebene bewegen können, wobei die Bewegung durch Unebenheiten der Rollenbahn eingeprägt wird. Deshalb sind die Füße vorteilhaft als federnde Gelenke, insbesondere als blattfederartige Gelenke, ausgeführt, welche kleine Bewegungen zulassen.In order to enable a possible low-wear sliding of the shuttle pallet in particular the roller conveyor, the feet of the load receiving bridges are inventively designed so that the side members can move to each other in the XZ plane, wherein the movement is impressed by unevenness of the roller conveyor. Therefore, the feet are advantageous as resilient joints, in particular as a leaf spring-like joints executed, which allow small movements.
Es wird in vorteilhafter Ausgestaltung der Erfindung vorgesehen, dass die Längsträger insbesondere aus einem Rohrabschnitt aus Baustahl oder Aluminium und besonders bevorzugt aus einem Rohr mit kreisringförmigen Querschnitt mit oder ohne Abflachung hergestellt werden. Dadurch kann der Kontakt zwischen den Rollenbahnen und Kettenförderern auf die Längsträger aus Baustahl oder einem Material mit kleinerem Elastizitäts-Modul beschränkt werden. Diese Längsträger sind wegen ihres Materials naturgemäß sehr verschleißfest und können daher lange Zeit ohne nennenswerten Verschleiß eingesetzt werden.It is provided in an advantageous embodiment of the invention that the side members are made in particular of a pipe section of structural steel or aluminum and more preferably of a tube with annular cross-section with or without flattening. Thereby, the contact between the roller conveyors and chain conveyors can be limited to the longitudinal beams of structural steel or a material with a smaller modulus of elasticity. These side rails are because of their Materials are naturally very wear-resistant and can therefore be used for a long time without significant wear.
Andere erfindungsgemäßen Längsträger bestehen aus Profilen mit biegesteifem Querschnitt, welche auf der Lauffläche einen größeren Kontaktbereich als ein Rohr mit kreisringförmigem Querschnitt zur Fördertechnik (Rollenbahnen etc.) aufweisen, um die Flächenpressung und die dadurch auftretenden Spannungen zu verkleinern. Erfindungsgemäß kann dies beispielsweise ein zur Lauffläche abgeflachtes, ansonsten aber im wesentliches kreisförmiges Rohr sein. Selbstverständlich kann dies auch durch andere Profile mit biegesteifem Querschnitt erreicht werden, welche auf der Lauffläche einen größeren Kontaktbereich zur Fördertechnik aufweisen. Dadurch wird die Flächenpressung (Hertz'sche Pressung) zwischen Längsträgern und beispielsweise den Rollen einer Rollenbahn verringert und so die dadurch auftretenden Spannungen verringert.Other longitudinal members according to the invention consist of profiles with rigid cross-section, which have on the tread a larger contact area than a tube with annular cross-section to the conveyor (roller conveyors, etc.) to reduce the surface pressure and the resulting stresses. According to the invention, this may be, for example, a flattened to the tread, but otherwise substantially circular tube. Of course, this can also be achieved by other profiles with rigid cross-section, which have a larger contact area to the conveyor on the tread. As a result, the surface pressure (Hertzian pressure) is reduced between longitudinal members and, for example, the rollers of a roller conveyor and thus reduces the stresses occurring thereby.
Die Hertz'sche Pressung kann weiter verringert werden, wenn ein Werkstoff mit kleinem Elastizitäts-Modul als Stahl eingesetzt wird. Dies kann beispielsweise Aluminium sein.The Hertzian pressure can be further reduced if a material with a small modulus of elasticity is used as steel. This can be aluminum, for example.
Des weiteren ist es durch die erfindungsgemäßen Längsträgern aus einem biegesteifen Profil möglich, auch schwer beladene Transportpaletten in den Lagerplätzen des Hochregallagers auf Querholmen zu lagern, da die erfindungsgemäßen Längsträger eine ausreichende Biegesteifigkeit aufweisen.Furthermore, it is possible by the inventive longitudinal members of a rigid profile to store even heavily loaded transport pallets in the storage bins of the high-bay warehouse on crossbars, since the longitudinal beams according to the invention have sufficient flexural rigidity.
Um sicherzustellen, dass von den Lastaufnahmebrücken die Gewichtskraft der darauf gelagerten Waren sicher in die Längsträger eingeleitet wird, sind an jeder Lastaufnahmebrücke Füße ausgebildet.To ensure that the weight of the goods stored thereon is securely introduced into the side members of the load-carrying bridges, feet are formed on each load-bearing bridge.
Die Längsträger sind durch eine Schnappverbindung oder eine Clipsverbindung mit den Lastaufnahmen für Brücken verbunden. Wird die Verbindung lösbar gestaltet, ist es auch möglich, einzelne Längsträger oder sogar einzelne Lastaufnahmebrücken im Fall von Beschädigungen auszutauschen, so dass die Wirtschaftlichkeit der erfindungsgemäßen Shuttle-Paletten weiter verbessert wird.The longitudinal members are connected by a snap connection or a clip connection with the load receptacles for bridges. If the connection is made detachable, it is also possible to exchange individual longitudinal members or even individual load-bearing bridges in the event of damage, so that the cost-effectiveness of the shuttle pallets according to the invention is further improved.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass die Lastaufnahmebrücken in einer Richtung orthogonal zu den Längsträgern biegesteif ausgebildet sind. In weiterer vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass zwischen zwei Lastaufnahmebrücken in Richtung der Längsträger erstreckende Abstandshalter vorgesehen sind. Dadurch ist sichergestellt, dass die Lastaufnahmebrücken sich nicht relativ zueinander verschieben können. Infolgedessen verändern sich die Abmessungen der erfindungsgemäßen Shuttle-Palette auch bei starker und mehrfacher Beanspruchung nicht und es wird ein problemloser störungsfreier Betrieb im automatisierten Lagersystem gewährleistet.In a further advantageous embodiment of the invention, it is provided that the load receiving bridges are formed rigid in a direction orthogonal to the longitudinal members. In a further advantageous embodiment of the invention it is provided that are provided between two load-receiving bridges in the direction of the longitudinal members extending spacers. This ensures that the load-carrying bridges can not move relative to each other. As a result, the dimensions of the shuttle pallet according to the invention do not change even with heavy and multiple stress and it is a trouble-free operation in the automated storage system guaranteed.
Die Abstandshalter und die Lastaufnahmebrücken können einstückig ausgebildet sein. Infolgedessen ist es zur Komplettierung der erfindungsgemäßen Shuttle-Palette lediglich erforderlich, an der Unterseite der Lastaufnahmebrücken die Längsträger, die vorzugsweise aus einem Rohr mit kreisringförmigem Querschnitt bestehen einzuclipsen. Die Lastaufnahmebrücken können bevorzugt aus Kunststoff, insbesondere HDPE und/oder recyceltem Kunststoff hergestellt werden. Dadurch können auch komplizierte Geometrien und eine gewichtsoptimierte Bauweise ohne weiteres realisiert werden.The spacers and the load receiving bridges may be integrally formed. As a result, it is only necessary to complete the shuttle pallet according to the invention, on the underside of the load receiving bridges the longitudinal beams, which preferably consist of a tube with annular cross-section einzuclipsen. The load-bearing bridges may be preferred made of plastic, in particular HDPE and / or recycled plastic. As a result, even complicated geometries and a weight-optimized design can be easily realized.
Damit die erfindungsgemäße Shuttle-Palette auch mit Regalbediengeräten, Gabelstaplern und anderem mehr angehoben und transportiert werden kann, ist vorgesehen, dass zwischen den Längsträgern an der Unterseite der Shuttle-Palette zwei in Längsrichtung verlaufende Ausnehmungen vorhanden sind. Vorteilhafterweise beträgt der Abstand der Mittelachsen der Ausnehmungen zwischen 340 mm und 400mm und besonders bevorzugt 370 mm.So that the shuttle pallet according to the invention can also be raised and transported with rack feeders, forklifts and others, it is provided that two recesses extending in the longitudinal direction are present between the longitudinal carriers on the underside of the shuttle pallet. Advantageously, the distance between the center axes of the recesses is between 340 mm and 400 mm, and particularly preferably 370 mm.
Die Höhe der Ausnehmung ist Vorteilhafterweise größer als 85 mm und die Breite der Ausnehmungen ist größer als 160 mm.The height of the recess is advantageously greater than 85 mm and the width of the recesses is greater than 160 mm.
In weiterer vorteilhafter Ausgestaltung der Erfindung ist vorgesehen, dass die Abmessungen der Shuttle-Palette, insbesondere deren Länge und Breite mindestens den genormten Maßen von sogenannten Transportpaletten, insbesondere Euro-Paletten entsprechen. Dadurch ist es erstens möglich, die genormten Transportpaletten auf die Shuttle-Paletten abzusetzen und es können die erfindungsgemäßen Shuttle-Paletten in bereits vorhandenen Hochregallagern eingesetzt werden. Dazu ist es gegebenenfalls lediglich erforderlich, die Höhe der Lagerplätze etwas zu vergrößern, und zwar um die Höhe der erfindungsgemäßen Shuttle-Palette.In a further advantageous embodiment of the invention, it is provided that the dimensions of the shuttle pallet, in particular its length and width correspond to at least the standard dimensions of so-called transport pallets, in particular Euro pallets. As a result, it is firstly possible to place the standardized transport pallets on the shuttle pallets and the shuttle pallets according to the invention can be used in already existing high-bay warehouses. For this it may only be necessary to slightly increase the height of the storage bins, namely by the height of the shuttle pallet according to the invention.
Um die Krafteinleitung zwischen der auf die erfindungsgemäßen Shuttle-Paletten aufgesetzten Transportpaletten und den Längsträgern weiter zu verbessern, ist in weiterer vorteilhaften Ausgestaltung der Erfindung vorgesehen, an einer Oberseite der Shuttle-Palette Lastaufnahmepunkte auszubilden, wobei die Abstände der Lastaufnahmepunkte voneinander den Abständen der Füße einer genormten Palette, insbesondere einer Euro-Palette entspricht. Dadurch wird die Krafteinleitung von der Transportpalette in die Shuttle-Palette an definierten Lastaufnahmepunkten konzentriert. Besonders vorteilhaft sind diese Lastaufnahmepunkte vertikal oberhalb der Füße der Shuttle-Palette angeordnet. Dadurch werden die Biegebeanspruchungen auf Grund von Gewichtskräften zwischen Transportpalette und Shuttle-Palette minimiert.In order to further improve the introduction of force between the transport pallets placed on the shuttle pallets according to the invention and the longitudinal carriers, the invention is provided in a further advantageous embodiment at an upper side of the shuttle pallet Form load receiving points, wherein the distances of the load receiving points from one another correspond to the distances of the feet of a standard range, in particular a euro pallet. This concentrates the introduction of force from the transport pallet into the shuttle pallet at defined load pick-up points. Particularly advantageously, these load-receiving points are arranged vertically above the feet of the shuttle pallet. As a result, the bending stresses due to weight forces between transport pallet and shuttle pallet are minimized.
Um den Verschleiß der erfindungsgemäßen Shuttle-Palette an der Oberseite im Bereich der Lastaufnahmepunkte zu verringern, kann in weiterer vorteilhafter Ausgestaltung der Erfindung vorgesehen sein, die Shuttle-Palette im Bereich der Lastaufnahmepunkte, insbesondere durch Schalen aus einem verschleißfesten Material, wie zum Beispiel Stahlblech, zu verstärken.In order to reduce the wear of the shuttle pallet according to the invention at the top in the region of the load receiving points, the shuttle pallet can be provided in the region of the load receiving points, in particular by shells made of a wear-resistant material, such as sheet steel, in a further advantageous embodiment. to reinforce.
