Abstract
Description
Die Erfindung bezieht sich auf ein Flurförderzeug zum Transport von Sonderpaletten nach Anspruch 1.The invention relates to an industrial truck for transporting special pallets according to
In der weltweiten Logistik haben sich Paletten als Ladehilfsmittel durchgesetzt. Eine Standardpalette (Europalette) hat eine Abmessung von 800 x 1200 Millimeter. Es sind auch andere Größen bekannt. Die Paletten werden vornehmlich von Flurförderzeugen transportiert und gestapelt, die mit Gabelzinken beziehungsweise Gabelarmen ausgelegt sind. Die übliche Ausführung ermöglicht lediglich den Transport einer Palette.In global logistics, pallets have become accepted as loading aids. A standard pallet (Euro pallet) has a dimension of 800 x 1200 millimeters. There are also other sizes known. The pallets are transported and stacked mainly by industrial trucks, which are designed with forks or fork arms. The usual design allows only the transport of a pallet.
In Einzelfällen (zum Beispiel im Einzelhandel) werden Lasten auf kleineren Paletten gestapelt und transportiert, die zum Beispiel die Abmessung von einem Viertel einer Europalette aufweisen. Die Waren werden, auf den Paletten stehend, direkt im Verkaufsraum aufgestellt. Um derartige Paletten zu handhaben, hat sich durchgesetzt, die kleineren Paletten so zu gestalten, dass sie jeweils die Hälfte, ein Drittel oder ein Viertel einer Standardpalette in Anspruch nehmen. Für die Lagerung in Regalen und den Transport werden Standardflurförderzeuge verwendet. Die kleineren Paletten sind auf Standardpaletten aufgestellt. Beim Einzelhändler müssen dann die kleineren Paletten von den großen heruntergenommen und in den Verkaufsraum gebracht werden.In isolated cases (for example in retail), loads are stacked and transported on smaller pallets, for example measuring one quarter of a Euro pallet. The goods are placed on the pallets, directly in the sales room. In order to handle such pallets, it has been accepted to make the smaller pallets so that they each occupy half, a third or a quarter of a standard pallet. For storage on shelves and transport standard trucks are used. The smaller pallets are set up on standard pallets. At the retailer, the smaller pallets must then be taken down by the big ones and taken to the showroom.
Für das Herunternehmen der kleinen Paletten von den großen und den Transport in den Verkaufsraum sind Spezialflurförderzeuge erforderlich. Sie müssen in der Lage sein, eine Stapelfunktion auszuführen, um die kleinen Paletten von den großen herunterzunehmen. Sie müssen außerdem in der Lage sein, die kleinen Paletten in den Verkaufsraum zu transportieren. Standardflurförderzeuge nehmen die kleinen Paletten jeweils auf einzelne Gabelzinken auf, was entsprechend unsicher ist. Außerdem benötigt ein Standardflurförderzeug zum Manövrieren viel Platz, der häufig nicht zur Verfügung steht.For the removal of the small pallets from the large ones and the transport to the sales area, special industrial trucks are required. she must be able to perform a stacking function to take down the small pallets from the big ones. You also need to be able to transport the small pallets into the sales room. Standard trucks take the small pallets on each individual forks, which is correspondingly uncertain. In addition, a standard truck for maneuvering requires a lot of space, which is often not available.
Es ist auch bereits bekannt, Kleinfahrzeuge vorzusehen, die mit einem mittigen Radarm und einem mittigen Lastarm versehen sind, um derartige Paletten zu transportieren und zu stapeln. Da die kleinen Paletten oftmals in Relation zu ihrer Grundfläche hoch beladen sind, ist es sinnvoll, die Unterstützung der Palette durch die einzelne Gabelzinke um weitere Elemente zu ergänzen. Es sind Haltewinkel bekannt, die am Gabelrücken so befestigt sind, dass sie die auf der Gabelzinke liegende Palette an den beiden, dem Gabelrücken zugewandten Ecken unterstützen. Dies setzt jedoch eine spezielle Ausführung der kleinen Paletten voraus, die meist nicht gegeben ist. In diesem Fall muss der Bediener die Handhabung der kleinen Paletten vorsichtig durchführen und gegebenenfalls die Last von Hand zusätzlich abstützen.It is also already known to provide small vehicles which are provided with a central wheel arm and a central load arm to transport and stack such pallets. Since the small pallets are often heavily loaded in relation to their base area, it makes sense to supplement the support of the pallet by the single fork to further elements. There are known brackets that are attached to the fork back so that they support the lying on the fork tine pallet at the two, the fork back facing corners. However, this requires a special design of the small pallets, which is usually not given. In this case, the operator must carefully handle the handling of the small pallets and optionally additionally support the load by hand.
Der Erfindung liegt die Aufgabe zugrunde, ein Flurförderzeug zum Transport von Sonderpaletten zu schaffen, das Stapel- und Transportvorgänge schnell und sicher mit wenig Platzbedarf und ohne große körperliche Anstrengung durchrühren kann.The invention has for its object to provide a truck for transporting special pallets that can quickly and safely stir stacking and transport operations with little space and without great physical effort.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of
Bei dem erfindungsgemäßen Flurförderzeug sind zwei parallel beabstandete Hubgerüstprofile seitlich am mittigen Radarm angeschweißt, vorzugsweise über Distanzklötze. Der Lastarmrücken ist in den Hubgerüstprofilen geführt, vorzugsweise über Rollen. Ein Lagerbauteil für einen Fahrantrieb mit einem schwenkbaren beziehungsweise lenkbaren Antriebsrad ist über gefederte Arme an den Hubgerüstprofilen angelenkt. Die Anlenkung erfolgt vorzugsweise an der Rückseite der Hubgerüstprofile.In the truck according to the invention two parallel spaced mast profiles are laterally welded to the central arm, preferably via spacer blocks. The load arm back is guided in the mast profiles, preferably via rollers. A bearing component for a traction drive with a pivotable or steerable drive wheel is articulated via sprung arms to the mast profiles. The articulation is preferably at the back of the mast profiles.
Das erfindungsgemäße Flurförderzeug weist mithin eine selbsttragende Konstruktion auf, die einfach herstellbar ist und zu einem leichten Gerät führt.The truck according to the invention thus has a self-supporting construction, which is easy to manufacture and leads to a lightweight device.
Vorteilhafte Ausgestaltungen des Anspruchs 1 sind in Unteransprüchen angegeben.Advantageous embodiments of
Nach einer Ausgestaltung der Erfindung sind an der Rückseite des Lastarmrückens parallel beabstandete Laschen angebracht für die Lagerung von Führungsrollen.According to one embodiment of the invention parallel spaced tabs are attached to the back of the Lastarmrückens for the storage of guide rollers.
Nach einer weiteren Ausgestaltung der Erfindung sind an einem an den Hubgerüstprofilen befestigten Haltebauteil beabstandet zwei Gummifederelementepaare eingebracht, die über Lenker mit Gummifederelementen am Lagerbauteil des Fahrantriebs gekoppelt sind. Ein Elementpaar kann jedoch auch durch ein einzelnes Element ersetzt werden, um eine Parallelführung zu erhalten. Derartige Gummifederelemente sind an sich bekannt. Sie bestehen aus einer äußeren und einer inneren Hülse, beispielsweise in Vierkantform wobei zwischen den Hülsen elastomeres Material eingebracht ist. Mit Hilfe einer derartigen Federanordnung wird für das Antriebsrad ein gewisser Bodenandruck erzeugt, der nach einer weiteren Ausgestaltung der Erfindung dadurch variabel ist, dass die Anbringung der ersten Federelemente in der Höhe an unterschiedlichen Orten gewählt werden kann.According to a further embodiment of the invention spaced two rubber spring element pairs are placed on a fixed to the mast profiles holding member, which are coupled via links with rubber spring elements on the bearing component of the traction drive. However, an element pair can also be replaced by a single element to obtain a parallel guide. Such rubber spring elements are known per se. They consist of an outer and an inner sleeve, for example in square shape with elastomeric between the sleeves Material is introduced. With the aid of such a spring arrangement, a certain Bodenandruck is generated for the drive wheel, which is variable according to a further embodiment of the invention characterized in that the attachment of the first spring elements in height can be selected at different locations.
Nach einer weiteren Ausgestaltung der Erfindung sind auf beiden Seiten der Hubgerüstprofile Lagerplatten an diesen angebracht, die an der Unterseite Lenkrollen lagern. Die Lagerplatten können nach einer weiteren Ausgestaltung der Erfindung Verbindungsstreben aufweisen, die ihrerseits mit den Hubprofilen verschweißt sein können. Die Lagerplatten dienen auch zur Abstützung von Batterien, vorzugsweise Lithiumzellen. Lithiumzellen beanspruchen bei gleichem nutzbarem Energieinhalt in Relation zu bisher üblichen Bleisäurebatterien wesentlich weniger Bauraum und sind außerdem leichter. Sie haben weiterhin den Vorteil, dass sie in einer kürzeren Zeit wieder geladen werden können als Bleisäurebatterien und im Gegensatz zu diesen wartungsfrei sind. Nach einer weiteren Ausgestaltung der Erfindung in diesem Zusammenhang ist vorgesehen, dass oberhalb der Lithiumzellen auf den Tragplatten weitere Lithiumzellen angeordnet sind, die mit einer Lithiumzelle oberhalb der Federanordnung für den Fahrantrieb ausgerichtet sind. Zum Erreichen einer Gesamtspannung von etwa 24 Volt sind daher vorzugsweise sieben dieser Zellen vorgesehen.According to a further embodiment of the invention bearing plates are attached to these on both sides of the mast profiles, which store at the bottom of castors. The bearing plates may comprise connecting struts according to a further embodiment of the invention, which in turn may be welded to the Hubprofilen. The bearing plates also serve to support batteries, preferably lithium cells. Lithium cells require much less space with the same useful energy content in relation to conventional lead-acid batteries and are also lighter. They also have the advantage that they can be recharged in a shorter time than lead-acid batteries and in contrast to these are maintenance-free. According to a further embodiment of the invention in this context, it is provided that above the lithium cells on the support plates further lithium cells are arranged, which are aligned with a lithium cell above the spring arrangement for the traction drive. To achieve a total voltage of about 24 volts, therefore, preferably seven of these cells are provided.
Das erfindungsgemäße Flurförderzeug weist auch eine Hubvorrichtung auf, um den Lastarm in der Höhe zu bewegen. Hierzu kann ein herkömmlicher Hydraulikantrieb genommen werden. Nach einer Ausgestaltung der Erfindung ist ein Spindelantrieb vorgesehen, dessen Elektromotor vorzugsweise parallel zur Spindel angeordnet ist und dessen Spindelmutter mit der Spindel zusammenwirkt, die mit zwei parallel beabstandeten weiteren Laschen an der Rückseite des Lastarmrückens in Wirkverbindung steht. Die Spindel ist vorzugsweise drehfest an den Laschen befestigt und der Motor treibt die Spindelmutter an. Ein Elektrospindelantrieb hat den Vorteil, dass dadurch ein "ölfreies" Fahrzeug erhalten wird, was insbesondere für einen Einsatz im Lebensmittelbereich von Vorteil ist. Vorzugsweise wird für den Fahrantrieb ein Direktantrieb vorgesehen. Ein Direktantrieb benötigt nur einen kleinen Bauraum und ist durch einen leisen Betrieb gekennzeichnet. Es kann jedoch auch ein Antrieb mit Getriebe, vorzugsweise bei ebenfalls liegendem Motor, vorgesehen werden.The truck according to the invention also has a lifting device to move the load arm in height. For this purpose, a conventional hydraulic drive can be taken. According to one embodiment of the invention, a spindle drive is provided, the electric motor preferably parallel is arranged to the spindle and the spindle nut cooperates with the spindle, which is in operative connection with two parallel spaced further tabs on the back of Lastarmrückens. The spindle is preferably rotatably attached to the tabs and the motor drives the spindle nut. An electric spindle drive has the advantage that an "oil-free" vehicle is thereby obtained, which is advantageous in particular for use in the food sector. Preferably, a direct drive is provided for the traction drive. A direct drive requires only a small space and is characterized by quiet operation. However, it can also be a drive with gear, preferably with also lying engine, are provided.
Die Lenkung des erfindungsgemäßen Flurförderzeugs kann über eine Deichsel erfolgen, wodurch das Fahrzeug als Mitgängerfahrzeug gekennzeichnet ist. Die Deichsel ist so gelagert, dass sie um mindestens +/-90° schwenkbar ist. Ihre Verbindung mit einer vorzugsweise vertikalen Lenkachse erfolgt vorzugsweise oberhalb von Fahrantrieb und Batterien. Alternativ kann auch eine Stehplattform mit dem Fahrzeug verbunden werden, die gegebenenfalls klappbar ist. Bei feststehender Stehplattform kann ein Lenkgeber von geringen Ausmaßen in Griffnähe angebracht sein, der über eine elektrische Lenkung das Antriebsrad lenkt.The steering of the truck according to the invention can take place via a drawbar, whereby the vehicle is characterized as a pedestrian vehicle. The drawbar is mounted so that it can be swiveled by at least +/- 90 °. Their connection with a preferably vertical steering axle is preferably carried out above the drive and batteries. Alternatively, a standing platform can be connected to the vehicle, which can be folded if necessary. In a fixed standing platform, a steering transmitter of small dimensions can be mounted close to the handle, which steers the drive wheel via an electric steering.
Nach einer anderen Ausgestaltung der Erfindung ist seitlich am Lastarmrücken jeweils ein Lasthalteelement angelenkt, das um eine annähernd vertikale Achse schwenkbar seitlich gegen eine von Lastarm aufgenommene Last anlegbar ist. Dadurch wird die Last auf der aufgenommenen Palette seitlich abgestützt. Die Lasthalteelemente werden nach dem Aufnehmen der kleinen Palette seitlich an diese herangeklappt, so dass der dem Antriebsteil zugewandte Teil der kleinen Palette und auch die darauf befindliche Ware seitlich zur Fahrtrichtung sicher gestützt werden kann. Höhe und Länge der Lasthalteelemente werden so gewählt, dass sie in der Ruheposition im Wesentlichen nicht über die Außenkontur des Fahrzeuges hinausragen.According to another embodiment of the invention, a load-holding element is articulated laterally on the load arm back, which can be applied laterally about an approximately vertical axis against a load received by the load arm. As a result, the load on the recorded pallet is supported laterally. The load-retaining elements become after receiving the small pallet folded laterally to this, so that the drive part facing part of the small range and also the goods located thereon can be safely supported laterally to the direction of travel. Height and length of the load-holding elements are chosen so that they do not protrude in the rest position substantially over the outer contour of the vehicle.
