Description

Verfahren zum Befördern von Paletten im Niederhub- und im angrenzenden Stapelbereich Process for conveying pallets in the low-lift and adjacent stacking area
Im Patentantrag P3120 883.5 ist von mir ein Verfahren für das Fördern von Paletten vorgeschlagen morden, daß dank der Verwendung eines neuar tigen Palett-Hand-Gabelhubwagens das Fördern von Paletten nicht nur im Niederhubbereich in Längs- und Queraufnahme ermöglicht, sondern sogar im darüber hinausgehenden Hubbereich, der bereits Stapeleigenschaften des Fördermittels bedingt. Die erreichbare Stapelhöhe ist etwa die Pritschen höhe eines Kombiwagens.In patent application P3120 883.5 a method for conveying pallets is proposed by me that thanks to the use of a new pallet hand pallet truck enables the conveyance of pallets not only in the low-stroke range in longitudinal and transverse pick-up, but even in the stroke range beyond that , which already causes stacking properties of the conveyor. The stack height that can be achieved is roughly the platform height of a station wagon.
Gegenstand eines Zusatzpatentantrages (P 31 35 852.7) ist eine Variante des Verfahrens, die sich daraus ergibt, daß für einen nicht geringen Teil möglicher Anwender - hinsichtlich des Förderns im Niederhubbereich - es ausreichend ist, wenn Paletten mit Bodenbrettern nur in Längsrichtung aufgenommen werden können, und - hinsichtlich des Förderns im Stapler- Hubbereich es ausreichend ist, wenn Paletten nur etwa bis zur Pritschenhöhe von Kombiwagen befördert werden können.The subject of an additional patent application (P 31 35 852.7) is a variant of the process, which results from the fact that for a not insignificant number of possible users - with regard to conveying in the low-lift area - it is sufficient if pallets with floor boards can only be picked up in the longitudinal direction, and - with regard to conveying in the forklift lifting area, it is sufficient if pallets can only be transported by station wagons up to the platform height.
Die bekannten im Wiederhub eingesetzten handbewegten Fördermittel lassen sich entweder gar nicht im Stapelhubbereich einsetzen, oder sie sind aufwendige Konstruktionen. Die gebräuchlichen Gabelhochhubwagen (HV) (Hand- gabelstapler wie Handwindenstapler, Pedalstapler, Hydraulikstapler oder durch Muskelkraft bewegte Elektrostapler) sind mindestens für Stapelhöhen über 1,50m konzipiert. Wegen der erforderlichen Standsicherheit besitzen sie gabelförmige Vierrad- (oder Fünfrad) Fahrgestelle mit breitspurig angeordneten Lauf- oder Tandemlaufrädern an den Gabelausläuferenden und mit mindestens zwei breitspurig angeordneten Lenkrädern oder Hilfslenkrädern am Lenkende und sind schon deshalb unnötig schwierig und unnötig unhandlich, und dies trifft erst recht im Einsatz im Nieder hubbereich zu.The known hand-operated conveyors used in the repetition either cannot be used at all in the stacking stroke area, or they are complex constructions. The standard high-lift pallet trucks (hand pallet trucks such as hand winch trucks, pedal stackers, hydraulic forklifts or electric forklifts moved by muscle power) are designed for stack heights of more than 1.50m. Because of the necessary stability, they have fork-shaped four-wheel (or five-wheel) chassis with wide-lane running or tandem running wheels at the fork ends and with at least two wide-running steering wheels or auxiliary steering wheels at the steering end and are therefore unnecessarily difficult and unnecessarily unwieldy, and this is especially true when used in the low-lift range.
Das Verfahren zum Fördern von Paletten im Niederhubbereich und im angrenzenden Stapelbereich besteht darin, daß so placierte Paletten mit neuartigen Fördermitteln bewegt werden. Entweder geschieht dies unter Verwendung eines neuartigen Palett-Hand-Gabelhubwagens, der im Niederhubbereich auf dem Boden placierte Paletten längs- und queraufnehmen kann und auch im Stapelbereich, oder es geschieht unter Verwendung des vorgeschlagenen Gabelhochhubwagens, der im Niederhubbereich Paletten nur längs aufnehmen kann, der aber in beiden Bereichen besonders wendig ist. Das Befördern selbst geschieht in an sich bekannter lileise (Unterfahren, Aufnehmen der Last, Absenken, Transportieren u. dgl.). In den Gebrauchsmusteranmeldungen G 81 33 460.5 und G 8133500.8 sind von mir diese neuartigen Fördermittel schon beschrieben worden.The method for conveying pallets in the low-lift area and in the adjacent stacking area is that pallets placed in this way are moved with novel conveying means. Either this is done using a new type of pallet hand pallet truck that can pick up pallets placed on the floor in the low-lift area along and across and also in the stacking area, or it is done using the proposed high-lift truck that can only take pallets lengthways in the low-lift area but is particularly agile in both areas. The transport itself takes place in a lileise known per se (driving under, lifting the load, lowering, transporting and the like). In the utility model applications G 81 33 460.5 and G 8133500.8 I have already described these new types of funding.
Der für die Anwendung des neuartigen Verfahrens vorgeschlagene Palett- Hand-Gabelhubwagen ist im Grunde genoninen ein gebräuchlicher handbewegter Gabelhubwagen, auf dem ein zweites Hubwerk aufgebaut ist. Die Hydraulik des üblichen Gabelhubwagens wird zusätzlich zur Betätigung des aufgebauten Hubwerks benutzt und besitzt die entsprechende Verbindung zun aufgesetzten Hubwerk. Das gebräuchliche Fahrwerk (Fahrgestell) besitzt nur eine Lenkachse am Lenkende (in an sich bekannter bleise) und Stützräder, die mit dem Gestänge des bekannten integrierten Hubwerks eines gebräuchlichen Gabelhubwagens verbunden sind.The pallet hand pallet truck proposed for the use of the novel method is basically genonine a common hand-operated pallet truck on which a second lifting mechanism is built. The hydraulic system of the conventional pallet truck is also used to actuate the built-in hoist and has the corresponding connection to the hoist. The usual chassis (chassis) has only one steering axle at the steering end (in lead known per se) and support wheels which are connected to the linkage of the known integrated lifting mechanism of a conventional pallet truck.
Der für die Anwendung des neuartigen Verfahrens vorgeschlagene Gabel- Hochhubwagen besitzt ein Gabelfahrwerk (Fahrgestell) mit nur einer Lenkachse am Lenkende und zwei Rollen oder Tandemrollen an den Gabelausläufern. Dies ist ein Fahrwerk, das erst durch den Aufbau eines an sich bekannten Hubwerkes seine Funktion erhält.The fork-lift truck proposed for the application of the new method has a fork carriage (chassis) with only one steering axle at the steering end and two rollers or tandem rollers on the fork extensions. This is a trolley that only functions after the construction of a hoist known per se.
Die aufgebauten Hubwerke beider vorgeschlagener Fördermittel besitzen vertikal geführte Lastschlitten mit daran befestigten zweizinkigen Lastgabeln, die parallel zur Fahrzeunlängsachse placiert sind. Die Lenk Achsen sind Achsen einer Schemellenkung. Sowohl für den Palett- Hand- Gabelhubwagen als auch für den Gabel-Hochhubwagen ist die Anwendung des Verfahrens im Stapelbereich allerdings nur in einer Höhe möglich, die etwa der Pritschenhöhe einer Kombiwagenpritsche entspricht. Die Standfestigkeit dieser Fördermittel ist trotz der geringen Spurweite (Zwillingsrad) groß genug, um allen Anforderungen der vorgeschriebenen Sicherheitsnormen zu erfüllen.The lifting mechanisms of both proposed conveyors have vertically guided load carriages with attached two-pronged load forks, which are placed parallel to the longitudinal axis of the vehicle. The steering Axes are axes of a steering control. However, for the pallet hand pallet truck as well as for the pallet truck, the use of the method in the stacking area is only possible at a height that corresponds approximately to the platform height of a combination truck platform. Despite the small track width (twin wheel), the stability of this funding is large enough to meet all the requirements of the prescribed safety standards.
Die beigegebene Abbildung 1 stellt das Ausführungsbeispiel des vorgeschlagenen Palett-Hand-Gabelhubwagens dar. 1.1 ist das integrierte Hubwerk, 1.2 das aufgebaute Hubwerk.The attached Figure 1 shows the embodiment of the proposed pallet hand pallet truck. 1.1 is the integrated hoist, 1.2 the assembled hoist.
Die Anwendung des vorgeschlagenen Verfahrens bietet deutliche Vorteile. Dort, wo schwere Stapler nicht eingesetzt werden können (Platzmangel), ermöglicht ein Befördern nach dem vorgeschlagenen Verfahren die Herabsetzung von Lohn- und Anschaffungskosten. Die Möglichkeit des Be- und Entladens von Rollwagen mit kommissionierten Paletten, die wiederum auf Lastwagen transportiert und gegebenenfalls mit einem mitgeführten Palett-Hand-Gabelhubwagen an Ort und Stelle (Einzelhandel) befördert werden können, bietet einen weiteren Vorteil. Für den Einsatz der vorgeschlagenen Fördermittel im Stapelbereich bedeutet die erstmalige Verwendung eines Gabelfahrwerks (Fahrgestells) mit nur einer Lenkachse eine bisher unbekannte Beweglichkeit in der Handhabung des Fördermittels. The use of the proposed method offers clear advantages. Where heavy forklifts cannot be used (lack of space), transport according to the proposed procedure enables wages and acquisition costs to be reduced. The possibility of loading and unloading trolleys with picked pallets, which in turn can be transported on trucks and, if necessary, transported on site (retail) with a pallet hand pallet truck that is carried along, offers another advantage. For the use of the proposed funds in the stacking area, the first use of a fork carriage (chassis) with only one steering axis means a previously unknown mobility in the handling of the funds.
