Description

Die Erfindung betrifft ein Lastaufnahmemittel zur ein- und mehrfachtiefen Ein- und Auslagerung von Gegenständen in ein Regal mit mindestens zweifachtiefer Lagerungsmöglichkeit mit den Merkmalen des Oberbegriffs des Patentanspruchs 1 sowie ein Verfahren zur ein- und mehrfachtiefen Einlagerung von Gegenständen mit einer Vorrichtung nach Anspruch 1.The invention relates to a load handling device for single and multi-depth storage and retrieval of objects in a rack with at least two-deep storage option with the features of the preamble of claim 1 and a method for one and multi-depth storage of objects with a device according to claim 1.

Bei doppeltiefer bzw. mehrfachtiefer Lagerung von Gegenständen, in der Regel Ladeeinheiten, in Regalen ist es bekannt, Regalbediengeräte mit Lastaufnahmemitteln zu verwenden, die mit teleskopisch ausfahrbaren Gabeln in die Regale hineingreifen und die Ladeeinheit aufnehmen oder absetzen. Die Ladeeinheiten werden üblicher Weise mit Hilfe geeigneter Aufsatzelemente so hoch positioniert, dass ein Lastaufnahmemittel sie untergreifen kann. Bekannt sind Hutprofile aus Stahl, die den Abstand zwischen Ladeeinheit und Auflage herstellen und den notwendigen Raum für den Durchgriff des Teleskoplastaufnahmemittels schaffen. Diese verwendeten Hutprofile sind aber nachteilig, weil sie einerseits wertvollen Lagerraum belegen, der nicht anderweitig genutzt werden kann und andererseits als Stahlbauelemente schwer und teuer sind.In double-deep or multi-deep storage of items, usually loading units in shelves, it is known to use stacker cranes with lifting devices that reach into the shelves with telescopically extendable forks and pick up or drop the load unit. The loading units are usually positioned so high by means of suitable attachment elements that a load-receiving means can reach under them. Are known hat profiles made of steel, which produce the distance between the loading unit and support and create the necessary space for the penetration of the telescopic load receiving means. These hat profiles used are disadvantageous because on the one hand occupy valuable storage space that can not be used elsewhere and on the other hand are difficult and expensive as steel components.

Um diese Stahlbauelemente einzusparen hat man Teleskoplastaufnahmemittel eingesetzt, deren vorzugsweise drei Teleskopabschnitte sich unabhängig voneinander verfahren lassen und somit relativ wenig Raum beim Ein- und Auslagern einnehmen. Teleskoplastaufnahmemittel werden deshalb, vorteilhafterweise in Verbindung mit sog. "versetzten Riegeln", bevorzugt im Regalbau eingesetzt, was durch den Verzicht auf Hutprofile zur Kosteneinsparung führt.To save these steel components has been used telescopic load receiving means, preferably three telescopic sections can be moved independently and thus occupy relatively little space during storage and retrieval. Telescopic load receiving means are therefore, advantageously used in conjunction with so-called "staggered bars", preferably in the rack construction, resulting in the absence of hat profiles for cost savings.

Bekannte Lastaufnahmemittel mit drei unabhängig voneinander ausfahrbaren Teleskoparmen werden gewöhnlich mit zwei Antrieben ausgestattet, wie dies in der gattungsbildenden DE 195 49 288 C1 beschrieben ist. Das dort gezeigte Lastaufnahmemittel zeigt einen Grundrahmen mit einem darauf angeordneten Teleskoparm, der drei ausfahrbare Teleskopabschnitte aufweist. Als Ausfahrantrieb werden zwei Umschlingungsantriebe verwendet, die am Grundrahmen angeordnet sind. Durch unterschiedliche Betätigung der Antriebe lassen sich über Antriebsketten die einzelnen Teleskopabschnitte aus- und einfahren; die Steuerung erfolgt über ein Wegmesssystem, z. B. über die Erfassung der Anzahl der Umdrehungen der Motorwellen der Umschlingungsantriebe. Beide Antriebe müssen exakt aufeinander abgestimmt gesteuert bzw. gebremst werden.Known load-carrying means with three independently extendable telescopic arms are usually equipped with two drives, as described in the generic DE 195 49 288 C1. The load receiving means shown there shows a base frame with a telescopic arm arranged thereon, which has three extendable telescopic sections. As an extension drive two wrapping drives are used, which are arranged on the base frame. By varying the actuation of the drives can be on drive chains, the individual telescope sections extend and retract; the control takes place via a distance measuring system, z. B. on the detection of the number of revolutions of the motor shafts of the belt drives. Both drives must be controlled or braked with precision.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, das bekannte Lastaufnahmemittel zu vereinfachen und damit kostengünstig herzustellen.The present invention has for its object to simplify the known load-handling means and thus produce cost.

Zur Lösung der Aufgabe wird erfindungsgemäß vorgeschlagen, dass zwischen dem Grundrahmen und dem ersten Teleskopabschnitt eine Verriegelungseinheit zum zeitweisen Verriegeln des ersten Teleskopabschnittes gegenüber dem Grundrahmen vorgesehen ist. Durch diese Verriegelungseinheit lässt sich einer der Antriebe einsparen, ohne die Funktionalität der Vorrichtung und die Unabhängigkeit der Aus- und Einfahrbewegungen der Teleskopabschnitte negativ zu beeinflussen. Mit dem eingesparten Antrieb entfällt auch das Zugmittel, mit dem beim Stand der Technik die Verbindung zwischen dem zweiten Antrieb und dem ersten Teleskopabschnitt herstellbar war.To achieve the object, the invention proposes that between the base frame and the first telescopic section a locking unit is provided for temporarily locking the first telescopic section relative to the base frame. By means of this locking unit, one of the drives can be saved without adversely affecting the functionality of the device and the independence of the extension and retraction movements of the telescopic sections. With the saved drive also eliminates the traction means with which in the prior art, the connection between the second drive and the first telescopic section was produced.

Durch geschickte Seilführung und Kombination der Verriegelung von Grundrahmen und erstem Teleskopabschnitt mit der erfindungsgemäßen Fixierung der an den Enden des ersten Teleskopabschnitts angeordneten Umlenkräder und/oder des ersten Zugmittels wird es ermöglicht, durch wechselweises geschicktes Blockieren von Zugmitteln und Teleskopabschnitten ein Ausfahren einzelner Teleskopabschnitte herbeizuführen oder zu verhindern.By clever cable guide and combination of the locking of the base frame and the first telescopic section with the fixation according to the invention at the ends of the first Telescopic section disposed deflecting wheels and / or the first traction means, it is made possible by alternately clever blocking of traction means and telescopic sections to bring about extension of individual telescopic sections or to prevent.

Wenn nach einem weiteren Merkmal der Erfindung vorgesehen ist, dass der erste und der zweite Teleskopabschnitt im ausgefahrenen Zustand des zweiten und dritten Teleskopabschnittes gegeneinander verriegelbar sind, so kann durch Entriegeln des ersten Teleskopabschnittes vom Grundrahmen und Drehrichtungsumkehr des Antriebsmotors der erste Teleskopabschnitt zusammen mit den bereits ausgefahrenen zweiten und dritten Teleskopabschnitten weiter ausgefahren werden.If it is provided according to a further feature of the invention that the first and the second telescopic section in the extended state of the second and third telescope section are locked against each other, so by unlocking the first telescopic section from the base frame and reversing direction of the drive motor of the first telescopic section together with the already extended second and third telescopic sections are extended further.

Selbstverständlich lässt sich die Erfindung auch bei Lastaufnahmemitteln anwenden, die mehr als drei Teleskopabschnitte aufweisen, wenn nur die Zugmittelführung in äquivalenter Weise erfolgt.Of course, the invention can also be applied to load-carrying means which have more than three telescopic sections, if only the Zugmittelführung takes place in an equivalent manner.

Ein Verfahren zur ein- und mehrfachtiefen Einlagerung von Gegenständen in einem Regal mit mindestens zweifachtiefer Lagerungsmöglichkeit mit einer vorstehend beschriebenen Vorrichtung ist durch die Merkmale a) bis e) des Patentanspruchs 5 gekennzeichnet.A method for storing one or more depths of articles in a rack with at least twice the storage possibility with a device described above is characterized by the features a) to e) of claim 5.

Durch die Vorrichtung und das Verfahren nach der Erfindung ergeben sich wesentliche Vorteile gegenüber dem Stand der Technik. Durch die Einsparung eines Antriebes mit zugehörigem Zugmittel bei Gewährleistung von unabhängiger Bewegbarkeit der einzelnen Teleskopabschnitte lassen sich Gewichtsreduzierungen des Teleskoparmes erzielen. Die mechanischen Bauteile der Verriegelungs- bzw. Fixiereinrichtungen sind um ein Vielfaches leichter als ein zweiter Antrieb. Mit den Gewichtseinsparungen gehen Einsparungen an Herstellkosten einher. Des Weiteren erhöht sich die Leistungsfähigkeit des Lastaufnahmemittels und des Bediengerätes, da die reduzierte Masse des Teleskoparmes entweder eine höhere Nutzlast zulässt und/oder höhere Beschleunigungen und Geschwindigkeiten ermöglicht. Das Schwingungsverhalten des Bediengerätes wird so günstig beeinflusst, dass auch bei kritischen Toleranzen ein einfaches Einfahren der Teleskopabschnitte möglich ist.By the apparatus and the method according to the invention, there are significant advantages over the prior art. By saving a drive with associated traction means while ensuring independent mobility of the individual telescopic sections can be achieved weight reductions of the telescopic arm. The mechanical components of the locking or fixing devices are many times lighter than a second drive. The weight savings are accompanied by savings in manufacturing costs. Furthermore, increased the performance of the load handler and the operator panel, as the reduced mass of the telescopic arm either allows a higher payload and / or allows higher accelerations and speeds. The vibration behavior of the control unit is so favorably influenced that a simple retraction of the telescopic sections is possible even with critical tolerances.

An embodiment of the invention will be described and explained below with reference to a schematic diagram. Show it:

In der grobschematischen Darstellung ist mit 1 der Grundrahmen des Lastaufnahmemittels bezeichnet, auf dem die Teleskopabschnitte 2, 3 und 4 vorzugsweise nach beiden Seiten ausfahrbar angeordnet sind. Mit 5 ist der Antrieb bezeichnet, der im Beispiel aus einem Umschlingungsantrieb mit einem Kettenrad besteht, das das Zugmittel, hier eine Antriebskette 6 teilweise umschlingt. Die Antriebskette 6 wird über die an beiden Seiten des Grundrahmens 1 angeordneten Umlenkkettenräder 9a geführt, wird dort in entgegengesetzter Richtung umgeleitet und überkreuz zu den an beiden Enden des erstem Teleskopabschnittes 2 angeordneten Umlenkkettenräder 9b geleitet, wo sie erneut umgelenkt und überkreuz zu Befestigungspunkten an beiden Enden des zweiten Teleskopabschnittes 3 geführt und dort befestigt wird.In the rough schematic representation, the base frame of the load-carrying means is denoted by 1, on which the telescopic sections 2, 3 and 4 are preferably arranged extendable to both sides. 5, the drive is designated, which consists in the example of a belt drive with a sprocket, which wraps around the traction means, here a drive chain 6 partially. The drive chain 6 is guided over the disposed on both sides of the base frame 1 Umlenkkettenräder 9a, where it is redirected in the opposite direction and crossed over to the arranged at both ends of the first telescopic section 2 Umlenkkettenräder 9b, where they again deflected and crossed to attachment points at both ends the second telescopic section 3 is guided and fastened there.

Wie bei 7 angedeutet, ist zwischen dem Grundrahmen 1 und dem ersten Teleskopabschnitt 2 eine Verriegelungseinrichtung vorgesehen, die die Ausfahrbarkeit des ersten Teleskopabschnittes 2 gegenüber dem Grundrahmen 1 zeitweise blockiert. Die Verriegelungseinrichtung 7 kann in herkömmlicher Weise mechanisch oder druckmittelbetrieben ausgeführt sein, im einfachsten Fall wird ein Bolzen in eine entsprechende Ausnehmung des gegenüberliegenden Teiles eingefahren und dort fixiert.As indicated at 7, between the base frame 1 and the first telescopic section 2, a locking device is provided which the extensibility of the first Telescope section 2 with respect to the base frame 1 temporarily blocked. The locking device 7 may be performed in a conventional manner mechanically or pressure fluid operated, in the simplest case, a bolt is retracted into a corresponding recess of the opposite part and fixed there.

An der Oberseite des ersten Teleskopabschnittes 2 ist an beiden Enden als Zugmittelpaar 10a und 10b eine sog. Flyerkette jeweils an den Endbereichen des Teleskopabschnittes 2 befestigt, die über die Umlenkräder 9c überkreuz zu Befestigungspunkten 11 an beiden Enden des letzten (dritten) Teleskopabschnittes 4 geführt ist.At the upper side of the first telescopic section 2, a so-called leaflet chain is fastened at both ends as traction means pair 10a and 10b to the end regions of the telescope section 2, which are guided over the deflection wheels 9c crosswise to attachment points 11 at both ends of the last (third) telescope section 4 ,

Eine zweite Fixiereinrichtung 8 ist am ersten Teleskopabschnitt 2 vorgesehen. Mit ihr sind entweder die Umlenkräder 9b auf dem ersten Teleskopabschnitt 2 oder die Kette 6 am ersten Teleskopabschnitt blockierbar. Die Fixiereinrichtung 8 ist fernbetätigt lösbar und verriegelbar.A second fixing device 8 is provided on the first telescopic section 2. With her either the deflecting wheels 9b on the first telescopic section 2 or the chain 6 on the first telescopic section can be blocked. The fixing device 8 is remote-controlled releasable and lockable.

Im Folgenden wird die Funktion des Lastaufnahmemittels der Erfindung beschrieben:The following describes the function of the load-carrying device of the invention:

Aus der in Figur 1 dargestellten Ausgangslage heraus soll das Lastaufnahmemittel in die in Figur 2 dargestellte Stellung verfahren werden. Die Teleskopabschnitte 3 und 4 sollen dabei unabhängig vom Teleskopabschnitt 2 ausgefahren werden. Der Antrieb 5 wird in Pfeilrichtung (Fig.2) betätigt und zieht über die Antriebskette 6, die am zweiten Teleskopabschnitt 3 bei 12 befestigt ist, den Teleskopabschnitt 3 (in der Zeichnung) nach rechts. Über das weitere Zugmittelpaar, die Flyerkette 10a, 10b, welche ihre Festpunkte an den Teleskopabschnitten 2 und 4 (bei 11) hat, wird bei der dargestellten Umlenkung und Führung der Flyerkette über die Umlenkräder 9c simultan zum Teleskopabschnitt 3 auch der Teleskopabschnitt 4 ausgefahren. Ein Ausfahren des ersten Teleskopabschnittes 2 ist unerwünscht und wird von der Verriegelungseinrichtung 7 verhindert, die die Relativbewegung zwischen dem Grundrahmen 1 und dem ersten Teleskopabschnitt 2 verhindert.From the starting position shown in Figure 1, the load receiving means is to be moved to the position shown in Figure 2. The telescopic sections 3 and 4 should be extended independently of the telescopic section 2. The drive 5 is actuated in the arrow direction (Figure 2) and pulls the drive chain 6, which is attached to the second telescopic section 3 at 12, the telescopic section 3 (in the drawing) to the right. Via the further pair of traction means, the leaf chain 10a, 10b, which has its fixed points on the telescopic sections 2 and 4 (at 11), the telescopic section 4 is extended simultaneously with the telescope section 3 in the illustrated deflection and guidance of the leaf chain over the guide wheels 9c. An extension of the first telescopic section 2 is undesirable and is of the Locking device 7 prevents, which prevents the relative movement between the base frame 1 and the first telescopic section 2.

Soll das Lastaufnahmemittel zur zweifachtiefen Ein- und Auslagerung voll ausgefahren werden, so wird, nachdem die Teleskopabschnitte 3 und 4 ihre Endstellung erreicht haben, die Verbindung zwischen Grundrahmen 1 und dem ersten Teleskopabschnitt 2 durch Entriegeln der Verriegelungseinrichtung 7 aufgehoben. Gleichzeitig wird über die Fixiereinrichtung 8 die Antriebskette 6 bzw. werden deren Kettenräder im Bereich des ersten Teleskopabschnittes 2 so fixiert, dass sich dadurch an dem ersten Teleskopabschnitt 2 quasi vorübergehend zwei Festpunkte für die Antriebskette 6 geschaffen werden. Diese "Festpunkte" bewirken bei einer Drehrichtungsumkehr des Antriebes 5 nun auch ein Ausfahren des ersten Teleskopabschnittes 2 mit den darauf angeordneten bereits ausgefahrenen zweiten und dritten Teleskopabschnitten 3 und 4 in Pfeilrichtung bis in eine Stellung, in der alle drei Teleskopabschnitte 2, 3 und 4 voll ausgefahren sind Figur 3.If the load-carrying means are to be fully extended for double-deep infeed and removal, then, after the telescopic sections 3 and 4 have reached their end position, the connection between the base frame 1 and the first telescopic section 2 is released by unlocking the locking device 7. At the same time, the drive chain 6 or its sprockets are fixed in the region of the first telescopic section 2 by way of the fixing device 8, so that two fixed points for the drive chain 6 are quasi temporarily created on the first telescopic section 2. These "fixed points" effect at a reversal of the drive 5 now also an extension of the first telescopic section 2 arranged thereon already extended second and third telescopic sections 3 and 4 in the arrow direction to a position in which all three telescopic sections 2, 3 and 4 full are extended Figure 3.

Die dargestellte Fixiereinrichtung 8 kann nach einem anderen Gedanken der Erfindung auch dadurch ersetzt werden, dass man vorübergehend eine feste Verbindung zwischen dem ersten Teleskopabschnitt 2 und dem zweiten Teleskopabschnitt 3 herstellt und dadurch die Fixierung schafft.According to another aspect of the invention, the illustrated fixing device 8 can also be replaced by temporarily establishing a firm connection between the first telescopic section 2 and the second telescopic section 3, thereby creating the fixation.
