Abstract

The invention concerns a rack serving unit (1) for a high-bay racking facility comprising at least one pole (2), which is mounted on a driven ground cross member (4) that is supported on the ground and can be displaced by means of displacing elements. The aim of the invention is to obtain a rack serving unit (1), which is hard wearing, can be displaced with a relatively high speed, and which has a small displacing resistance and a low starting mass. To this end, the invention provides that the displacing elements consist of air cushions (5) that are subjected to the action of a pressurized gas. The gas exiting from the air cushion (5) forms, between the ground (6) and the air cushion (5), an air film on which the ground cross member (4) can be displaced.

Description

Beschreibungdescription
Regalbediengerat für ein RegallagerStorage and retrieval machine for a shelf warehouse
Die Erfindung betrifft ein Regalbediengerat für eine Regallager gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a storage and retrieval unit for a rack storage according to the preamble of claim 1.
Es ist allgemein bekannt, dass Regalbediengeräte in Regallagern eingesetzt werden, um die verschiedensten Güter ein- und auszulagern. Hierzu weisen die Regalbediengeräte einen vertikalen Mast auf, an dem eine Ein- und Auslagerungsvorrichtung höhenverfahrbar ist. Der Mast ist meist an einer Bodentraverse befestigt, die quer zum Mast verläuft. An der Bodentraverse sind in Verfahrrichtung beabstandete Räder angeordnet, über die das Regalbediengerat einer Fahrschiene oder direkt am Boden abgestützt ist. Die Räder sind häufig zumindest teilweise aus Plastikmaterialien hergestellt. Zum Verfahren des Bediengerätes werden die Räder beispielsweise mittels eines elektrischen Antriebsmotors angetrieben.It is generally known that storage and retrieval machines are used in rack stores to store and remove a wide variety of goods. For this purpose, the storage and retrieval machines have a vertical mast on which a storage and retrieval device can be moved in height. The mast is usually attached to a floor traverse that runs across the mast. Wheels are arranged on the floor traverse in the direction of travel, by means of which the storage and retrieval unit of a travel rail or directly on the floor is supported. The wheels are often made at least partially of plastic materials. To move the control unit, the wheels are driven, for example, by means of an electric drive motor.
Nachteilig ist bei den bekannten Regalbediengeräten, dass die Laufräder einem relativ hohen Verschleiß unterliegen. Zur Verringerung des Verschleißes wird die Laufgeschwindigkeit der Räder relativ klein gewählt; zumindest wird die Laufge- schwindigkeit der Räder regelmäßig begrenzt. Darüber hinaus ist das Anfahrmaß der bekannten Regalbediengeräte relativ groß .A disadvantage of the known storage and retrieval machines is that the wheels are subject to relatively high wear. To reduce wear, the running speed of the wheels is chosen to be relatively low; at least the running speed of the wheels is limited regularly. In addition, the approach dimension of the known storage and retrieval machines is relatively large.
Die Aufgabe der Erfindung ist es, ein Regalbediengerat vorzu- schlagen, das verschleißarm und mit relativ hoher Geschwindigkeit verfahrbar ist. Außerdem soll dieses Regalbediengerat einen geringen Verfahrwiderstand aufweisen und ein tiefes Anfahrmaß ermöglichen. Die Lösung dieser Aufgabe ist durch die im Anspruch 1 angegebenen Merkmale gegeben. Die kennzeichnenden Merkmale der Unteransprüche enthalten vorteilhafte Ausgestaltungen.The object of the invention is to propose a storage and retrieval unit that can be moved with little wear and at a relatively high speed. In addition, this storage and retrieval machine should have a low travel resistance and enable a low approach dimension. The solution to this problem is given by the features specified in claim 1. The characterizing features of the subclaims contain advantageous refinements.
Die Lösung sieht vor, dass die Verfahrelemente aus Luftkissen gebildet sind, welche mit einem unter Druck stehenden Gas beaufschlagt werden, wobei das aus dem Luftkissen jeweils austretende Gas zwischen dem Boden und dem Luftkissen einen Luftfilm bildet, auf dem die Bodentraverse verfahrbar ist.The solution provides that the traversing elements are formed from air cushions which are pressurized with a gas under pressure, the gas emerging from the air cushion forming an air film between the floor and the air cushion on which the floor crossmember can be moved.
Die Luftkissen sind geräuscharm und setzen dem Verfahren des Regalbediengeräts nur einen geringen Reibungswiderstand entgegen. Darüber hinaus ist die Bodenbelastung aufgrund der größeren Auflagefläche geringer und eine höhere Verfahrge- schwindigkeit möglich. Die Luftkissen sind relativ flachbauend, so dass ein tieferes Anfahrmaß problemlos erreichbar ist, wodurch die Kosten reduziert werden. Da das Regalbediengerat ohne Bodenfahrschiene auskommt, erreicht es grundsätzlich ein geringeres unteres Anfahrmaß. Das gesamte Gerät kann also in Y-Richtung (Mastlängserstreckungsrichtung) um einen Verfahrweg Y verfahren und somit der Aushub der Ladung aus dem Regal bewerkstelligt werden. Darüber hinaus ist das Regalbediengerat für Kurvenfahrten nicht an eine Schienenführung gebunden. Auch ist ein Umsetzbrückenbetrieb auf Luftkis- senbasis einfacher möglich (leichtes Verfahren der Umsetzbrücke in den Bereich außerhalb des Regalganges, da es schienenunabhängig ist) .The air cushions are low-noise and only counter the movement of the storage and retrieval machine with low frictional resistance. In addition, due to the larger contact area, the floor load is lower and a higher travel speed is possible. The air cushions are relatively flat, so that a lower approach dimension can be reached easily, which reduces costs. Since the storage and retrieval machine does not need a floor track, it generally has a lower lower approach dimension. The entire device can thus be moved in the Y direction (longitudinal direction of the mast) by a travel path Y and the load can thus be excavated from the rack. In addition, the storage and retrieval unit for cornering is not bound to a rail guide. Air cushion-based transfer bridge operation is also easier (easy movement of the transfer bridge into the area outside the rack aisle, since it is rail-independent).
Kostengünstig ist es, wenn als Gas Luft verwendet wird.It is inexpensive if air is used as the gas.
Bei einer einfachen Ausführung ist das Luftkissen aus einer Tragplatte mit einem Pressluftanschluss, einer Membran und einer Stützplatte gebildet. Zweckmäßigerweise ist der Pressluftanschluss als Schnellkupplung ausgebildet.In a simple version, the air cushion is formed from a support plate with a compressed air connection, a membrane and a support plate. The compressed air connection is expediently designed as a quick coupling.
Eine wirksame und kostengünstige Führung wird erreicht, wenn die Bodenführung längs des Verfahrweges eine ebene glatte Bodenfläche und rechtwinklig ausgebildete Seitenführungselemente umfasst, die eine vertikale Geräteführung und Umsturzsicherung aufweisen.Effective and cost-effective guidance is achieved if the floor guide along the travel path comprises a flat, smooth floor surface and right-angled side guide elements which have vertical implement guidance and fall protection.
Reibungskräfte können reduziert werden, wenn die Seitenführungselemente mit vertikalen und horizontalen Rollen oder Rädern zusammenwirken.Frictional forces can be reduced if the side guide elements interact with vertical and horizontal rollers or wheels.
Technisch einfach ist es, wenn die Bodentraverse mittels eines stationär am Gangende angeordneten Verfahrantriebs mit einer Kette, einem Zahnriemen oder einem Seil als Zugmittel oder einem an der Bodentraverse drehgelagerten Motor angetriebenen Reibrad verfahrbar ist.It is technically simple if the floor cross-member can be moved by means of a traversing drive that is stationary at the end of the aisle, with a chain, a toothed belt or a rope as a traction device, or a friction wheel driven on the floor cross-member.
Zur Erhöhung der Stabilität der Führung wird vorgeschlagen, dass der Mast an seinem oberen Ende an einer Trag- und Führungsschiene abgestützt ist.To increase the stability of the guide, it is proposed that the mast at its upper end be supported on a support and guide rail.
Die Erfindung wird nachfolgend anhand einer Zeichnung näher beschrieben. Es zeigen:The invention is described below with reference to a drawing. Show it:
Fig. 1 ein Regalbediengerat mit Luftkissen,1 a stacker crane with air cushions,
Fig. 2 eine Ausführung einer am Boden angeordneten Seiten- führung und2 shows an embodiment of a side guide arranged on the floor and
Fig. 3 eine Seitenansicht der Seitenführung gemäß Fig. 1. Fig. 1 zeigt ein Regalbediengerat 1 für ein Regallager (nicht dargestellt) . Das Regalbediengerat weist einen vertikalen Mast 2 in Form von zwei beabstandeten parallelen Vertikalträgern 2a auf, deren obere freie Enden mittels eines Verbin- dungsträgers 3 miteinander verbunden sind. Selbstverständlich kann der Mast 2 auch aus einem einzigen Vertikalträger 2a gebildet sein. Im Bodenbereich sind die beiden Vertikalträger 2a durch eine quer zu den Vertikalträgern 2a verlaufenden Bodentraverse 4 verbunden. Mittels Luftkissen 5 als Verfahrele- mente ist die Bodentraverse 4 am Boden 6 abgestützt. In Fig. 1 sind die Luftkissen 5 direkt unterhalb der Vertikalträger 2a angeordnet. Auf dem Boden befinden sich zwei beabstandete Seitenführungselemente 7 in Form von Schienen, an denen Seitenführungsräder 8 zur seitlichen Führung der Bodentraverse 7 vorgesehen sind. Die Seitenführungselemente 7 dienen gleichzeitig als Umsturzsicherung, wozu sie an ihrem oberen Ende einen horizontalen Steg 7a aufweisen, an dem innenseitig (auf der dem Boden 6 zugewandten Seite) an der Bodentraverse 4 drehgelagerte Rollen 8a abrollen.3 shows a side view of the lateral guide according to FIG. 1. Fig. 1 shows a storage and retrieval unit 1 for a shelf storage (not shown). The storage and retrieval unit has a vertical mast 2 in the form of two spaced-apart parallel vertical supports 2a, the upper free ends of which are connected to one another by means of a connecting support 3. Of course, the mast 2 can also be formed from a single vertical support 2a. In the floor area, the two vertical beams 2a are connected by a floor cross member 4 running transversely to the vertical beams 2a. The floor cross-member 4 is supported on the floor 6 by means of air cushions 5 as travel elements. In Fig. 1, the air cushions 5 are arranged directly below the vertical support 2a. On the floor there are two spaced side guide elements 7 in the form of rails, on which side guide wheels 8 are provided for lateral guidance of the floor cross member 7. The side guide elements 7 serve at the same time as fall protection, for which purpose they have a horizontal web 7a at their upper end, on which rollers 8a, which are rotatably mounted, roll on the inside (on the side facing the floor 6) on the floor cross member 4.
Oberhalb des Regalbediengerätes 1 befindet sich eine Führungsschiene 9, an der das Regalbediengerat 1 mittels oberen Führungsrollen 10 abgestützt ist.Above the storage and retrieval unit 1 there is a guide rail 9 on which the storage and retrieval unit 1 is supported by means of upper guide rollers 10.
Ein Hubwagen 11 ist längs der Vertikalträger 2a verfahrbar, wobei der Antrieb mittels Seilen 12 erfolgt, die mittels eines Antriebsmotors 13 von einer Seiltrommel (nicht gezeigt) abwickelbar bzw. auf diese aufwickelbar sind. Dabei werden die Seile 12 am Verbindungsträger 3 mittels frei drehbarer Rollen 14 umgelenkt. Die Stromversorgung erfolgt über einen in Fig. 1 rechts unten schematisch gezeigten Schaltkasten 15. Es ist auch möglich den Hubwagen über einen Zahnriemen oder einer Kette längs der Vertikalträger zu verfahren Die ein- und auszulagernden Güter, von denen in Fig. 1 ein quaderförmiges Gut 16 gezeigt ist, werden mittels einer schematisch dargestellten Ein- und Auslagerungsvorrichtung 17 ein- und ausgelagert.A lifting truck 11 can be moved along the vertical supports 2a, the drive being effected by means of ropes 12 which can be unwound from a rope drum (not shown) by means of a drive motor 13 or wound thereon. The ropes 12 are deflected on the connecting support 3 by means of freely rotatable rollers 14. The power supply takes place via a switch box 15 shown schematically in the lower right-hand corner of FIG The goods to be put in and out, of which a cuboid good 16 is shown in FIG. 1, are put in and out by means of a schematically illustrated storage and retrieval device 17.
Der Antrieb der Bodentraverse 4 kann mittels eines stationär am Gangende angeordneten Fahrantriebs mit einer Kette, einem Zahnriemen oder einem Seil als Zugmittels erfolgen. Alterna- tiv ist es auch möglich, dass hierzu ein motorangetriebenes Reibrad verwendet wird, welches an der Bodentraverse 4 drehgelagert ist (beides nicht gezeigt) .The floor traverse 4 can be driven by means of a traction drive arranged stationary at the end of the aisle with a chain, a toothed belt or a rope as a traction device. Alternatively, it is also possible for this purpose to use a motor-driven friction wheel which is rotatably mounted on the floor cross member 4 (neither of which is shown).
Die Luftkissen 5 können eine Tragplatte mit einem Pressluft- anschluss (zum schnellen Anschließen der Pressluftzufuhr), eine Membran und eine Stützplatte aufweisen. Sie werden mit einem unter Druck stehenden Gas, vorzugsweise Druckluft, beaufschlagt, wobei aus dem Luftkissen 5 auf der dem Boden 6 jeweils zugewandten Seite jeweils Druckluft austritt, die einen dünnen Luftfilm zwischen dem Luftkissen 5 und dem Boden 6 erzeugt. Dieser Luftfilm sorgt dafür, dass das Regalbediengerat 1 beim Verfahren über den Boden 6 nahezu reibungslos gleitet .The air cushions 5 can have a support plate with a compressed air connection (for quick connection of the compressed air supply), a membrane and a support plate. They are pressurized with a pressurized gas, preferably compressed air, with compressed air emerging from the air cushion 5 on the side facing the base 6, which produces a thin air film between the air cushion 5 and the base 6. This air film ensures that the storage and retrieval unit 1 glides almost smoothly over the floor 6 when it is being moved.
Die Bodenführung des Regalbediengerätes 1 wird durch eine ebene glatte Bodenfläche 18 des Bodens 6 gebildet. Die Bodenfläche 18 kann auch durch eine separate Bodenschicht gebildet sein (wie Fig. 3 schematisch zeigt).The floor guide of the storage and retrieval unit 1 is formed by a flat, smooth floor surface 18 of the floor 6. The bottom surface 18 can also be formed by a separate bottom layer (as schematically shown in FIG. 3).
Fig. 2 zeigt eine einfache Ausführung der Seitenelemente 7 zur Seitenführung, wobei vom Regalbediengerat 1 nur die Bodentraverse 4 mit den Seitenführungsrädern 8 gezeigt ist. Die Seitenführungselemente 7 sind bei dieser Ausführung als rechtwinklige Profilträger ausgebildet, die einander gegenüberliegend angeordnet sind. An den dadurch einander gegenüberliegenden vertikalen Seitenflächen rollen die Seitenführungsräder 8 innenseitig ab.Fig. 2 shows a simple embodiment of the side elements 7 for lateral guidance, only the floor cross member 4 with the lateral guide wheels 8 being shown from the storage and retrieval unit 1. The side guide elements 7 are as in this embodiment rectangular profile beams are formed, which are arranged opposite one another. The lateral guide wheels 8 roll on the inside on the vertical side surfaces which are thereby opposite one another.
Fig. 3 zeigt die Seitenführung gemäß Fig. 1 in einer Seitenansicht. Die Seitenführungselemente 7 weisen - im Unterschied zu Fig. 2 - an ihrem oberen Ende die zur Bodentraverse 4 hin gerichteten Stege 7a auf. Fig. 3 shows the side guide of FIG. 1 in a side view. In contrast to FIG. 2, the side guide elements 7 have, at their upper end, the webs 7a directed towards the floor cross member 4.
