Abstract

The store has a warm zone (W) for storing un-refrigerated goods and a cold zone (K) for storing goods at a temperature of between +2 and +10 degrees C. The cold zone is provided by a storage layer extending beneath the warm zone and supplied with cold air at its base and at the interface between the cold zone and the warm zone. A thermal insulation layer is provided between the cold zone and the warm zone. The cold zone is placed below ground level.

Description

Die Erfindung bezieht sich auf ein Lager, insbesondere ein mit mehreren Regalbediengeräten ausgestattetes mehrgassiges Hochregallager, zur gemeinsamen Lagerung von ungekühlter Ware in einer Warmzone und typischerweise auf +2°C bis +10°C gekühlter Ware in einer Kaltzone.The invention relates to a warehouse, in particular a multi-aisle high-bay warehouse equipped with several storage and retrieval devices, for the common storage of uncooled goods in a warm zone and typically goods cooled to + 2 ° C. to + 10 ° C. in a cold zone.

Im Bereich der Nahrungs- und Genußmittelindustrie werden heutzutage immer mehr Waren ohne Konservierungsstoffe hergestellt. Diese Waren können nun nicht mehr einfach so wie Trockenwaren ohne besondere Berücksichtigung von Temperaturgrenzwerten gelagert werden, sondern hier ist wegen der Anforderung an die Haltbarkeit der Waren eine gekühlte Lagerung, typischerweise in einem Temperaturbereich von +2°C bis +10°C, erforderlich.In the food and beverage industry, more and more goods are being manufactured without preservatives. These goods can no longer simply be stored like dry goods without special consideration of temperature limit values, but because of the requirement for the shelf life of the goods, refrigerated storage, typically in a temperature range of + 2 ° C to + 10 ° C, is required.

Bei handelsüblichen Lagern wurden aus diesem Grund jeweils zwei nebeneinander angeordnete baulich getrennte Hochregallager gleicher Bauhöhe erstellt, von denen eins als Kühllager und das andere als Standardlager für Trockenwaren dient. Um während der Sommermonate hohe Strahlungsverluste des Kühllagers zu vermeiden, muß dieses relativ stark isoliert werden, damit aus ökonomischen und ökologischen Gründen Kühlaggregate geringer Leistung eingesetzt werden können.For this reason, in commercially available warehouses, two structurally separate high-bay warehouses of the same height, one next to the other, were created, one of which serves as a cold store and the other as a standard warehouse for dry goods. In order to avoid high radiation losses from the cold store during the summer months, the cold store must be insulated relatively strongly so that low-power cooling units can be used for economic and ecological reasons.

Im Regelfall erreicht die Kühlware nicht die Menge der Trockenware. Dies kann dazu führen, daß das Kühllager eingassig und das Standardlager mehrgassig ist. In einem eingassigen Lager kann jedoch der Ausfall eines Regalbediengerätes schwere Störungen des Betriebs nach sich ziehen. Bei einem mehrgassigen Lager, wie es für das Standardlager üblich ist, besteht dieses Problem jedoch nicht.As a rule, the chilled goods do not reach the amount of dry goods. This can lead to the cold store having one aisle and the standard warehouse having multiple aisles. In a single-aisle warehouse, however, the failure of a storage and retrieval machine can result in serious disruptions to operations. With a multi-aisle warehouse, as is common for the standard warehouse, this problem does not exist.

Aufgabe der Erfindung ist es, ein Lager der eingangs genannten Art so auszubilden, daß der Lagerbetrieb bei partiellem Ausfall von Transportmitteln möglichst weitgehend erhalten bleibt.The object of the invention is to design a warehouse of the type mentioned at the outset in such a way that warehouse operation is maintained as far as possible in the event of partial failure of the means of transport.

Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß die Kaltzone in einer Schicht unterhalb der Warmzone angeordnet ist und daß an der Basis der Kaltzone gekühlte Luft eingespeist und im Übergangsbereich zwischen Warm- und Kaltzone ausgespeist wird.According to the invention, this object is achieved in that the cold zone is arranged in a layer below the warm zone and in that cooled air is fed in at the base of the cold zone and is fed out in the transition region between the warm and cold zones.

Die Erfinder nutzen dabei die Erkenntnis aus, daß mit einer derartigen Kaltluftführung ein räumlich stabiler Übergangsbereich aufrecht erhalten werden kann, ohne daß dazu aufwendige bauliche Maßnahmen getroffen werden müssen.The inventors exploit the knowledge that a spatially stable transition area can be maintained with such a cold air duct without the need for complex structural measures.

Eine erste Ausbildung der Erfindung ist dadurch gekennzeichnet, daß die ausgespeiste Luft über eine Kühlanlage gekühlt und dann wieder in das Lager eingespeist wird. Dieses Vorgehen ist ausgesprochen energieökonomisch.A first embodiment of the invention is characterized in that the exhausted air is cooled by a cooling system and then fed back into the warehouse. This procedure is extremely energy-efficient.

Dadurch, daß zwischen der Warmzone und der Kaltzone im Regalbereich eine thermische Isolation vorgesehen ist, läßt sich der Übergangsbereich noch zusätzlich stabilisieren und thermisch optimieren.Because thermal insulation is provided in the shelf area between the warm zone and the cold zone, the transition area can be additionally stabilized and thermally optimized.

Besonders vorteilhaft ist es bei einem Lager gemäß der Erfindung, daß die Kühlzone unterhalb des Erdbodenniveaus angeordnet ist. Dabei wird der Effekt ausgenützt, daß im Erdboden zu jeder Jahreszeit eine etwa konstante Temperatur von +10°C vorliegt. Insofern bietet es sich auch an, im Boden- und Wandbereich des Lagers unterhalb des Erdoberflächenniveaus auf eine thermische Isolierung zu verzichten.It is particularly advantageous in a bearing according to the invention that the cooling zone is arranged below the ground level. The effect is exploited that the temperature of the earth is approximately constant at + 10 ° C in every season. In this respect, it makes sense to do without thermal insulation in the floor and wall area of the bearing below the earth's surface level.

Im Falle einer Erweiterung des Lagers kann selbstverständlich jeweils gassenweise angebaut werden. Bei einer Erhöhung des Volumens der Kaltzone, die auf Kosten des Volumens der Warmzone gehen kann, ist es beim erfindungsgemäßen Konzept leicht möglich, die Ausspeisestellen für die Kühlluft einfach höher anzubringen, wobei diese Höhendifferenz zweckmäßigerweise das n-fache der Höhe einer Lagerebene ausmacht. Sofern eine sehr schnelle Umstellung gewünscht sein sollte, ist es nach einer weiteren Ausbildung der Erfindung auch möglich, daß in mehreren Höhenstufen Mittel zur Ausspeisung der gekühlten Luft vorgesehen sind, wobei ein wahlweises Umschalten der Luftführung auf jeweils eine Höhenstufe erfolgt.In the event of an expansion of the warehouse, it is of course possible to add aisles in each case. If the Volume of the cold zone, which can be at the expense of the volume of the warm zone, it is easily possible with the concept according to the invention to simply place the exit points for the cooling air higher, this height difference expediently being n times the height of a storage level. If a very quick changeover should be desired, it is also possible according to a further embodiment of the invention that means for supplying the cooled air are provided in several height levels, the air duct being optionally switched to one height level.

Sofern Ein-, Aus- oder Umlagervorgänge zwischen Warm- und Kühlzone erfolgt, sollte gemäß einer weiteren vorteilhaften Ausbildung der Erfindung nicht unbedingt der kürzeste Verfahrweg für die Regalbediengeräte ausgewählt werden, sondern ohne Rücksichtnahme auf die Gesamtverfahrstrecke sollte die Verfahrbahn im Hinblick auf minimale Luftverwirbelungen in der Kaltzone ausgelegt werden. Damit wird ein unnötiges Aufheizen dieser Zone vermieden.If storage, removal or relocation processes take place between the warm and cooling zones, the shortest travel path for the storage and retrieval machines should not necessarily be selected according to a further advantageous embodiment of the invention, but the travel path should be taken into account with regard to minimal air turbulence in the, regardless of the total travel distance Cold zone can be designed. This avoids unnecessary heating of this zone.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher erläutert.An embodiment of the invention is shown in the drawing and is explained in more detail below.

In der Anlage ist in verkürzter Darstellung ein Hochregallager gezeigt, das auf eine Betonwanne B aufbauen möge, die in den Erdboden eingelassen ist. Dieses mehrgassige Hochregallager weist Regalreihen R1 bis Rn auf. Zwischen den Regalreihen R1 bis Rn befinden sich Gassen G1 bis Gn, in denen der Übersichtlichkeit halber nicht dargestellte Regalbediengeräte verfahren werden können.A shortened representation of a high-bay warehouse is shown in the system, which may be built on a concrete trough B, which is embedded in the ground. This multi-aisle high-bay warehouse has shelf rows R1 to Rn. Between the rows of racks R1 to Rn there are aisles G1 to Gn in which, for the sake of clarity, rack operating devices (not shown) can be moved.

Das gesamte Lager beinhaltet eine gekühlte Kaltzone K, bei der temperaturempfindliches Lagergut in einem Temperaturbereich von +2°C bis +10°C eingelagert wird und eine Warmzone W für temperaturunempfindliches Lagergut, das beispielsweise bei Raumtemperatur zwischen +15 und +30°C lager- und handhabbar ist. Zwischen der Kaltzone K und der Warmzone W befindet sich eine Übergangszone UE.The entire warehouse contains a cooled cold zone K, in which temperature-sensitive stored goods are stored in a temperature range of + 2 ° C to + 10 ° C, and a warm zone W for temperature-insensitive stored goods, which are stored, for example, at room temperature between +15 and + 30 ° C. and manageable is. There is a transition zone UE between the cold zone K and the warm zone W.

Allein die Tatsache, daß kalte Luft schwerer ist als warme Luft, reicht nun jedoch nicht aus, die Übergangszone UE so scharf als definierte Trennung der beiden Lagerbereiche festzuhalten, wie dies erforderlich ist, um das Lagergut nicht zu schädigen. Daher müssen besondere Maßnahmen getroffen werden, um die Übergangszone UE stabil und schmal zu halten.The mere fact that cold air is heavier than warm air is not enough to hold the transition zone UE as sharply as a defined separation of the two storage areas as is necessary in order not to damage the stored goods. Special measures must therefore be taken to keep the transition zone UE stable and narrow.

Dies geschieht dadurch, daß von einer der Übersichtlichkeit halber nicht dargestellten Kältemaschine Kaltluft über Einlässe E1 bis En am Fuße des Lagers eingeblasen wird, wie dies in der Darstellung durch kleine Pfeile angedeutet ist, und daß die Kaltluft über Auslässe A1 bis An aus dem Lagerbereich abgeführt wird, wobei sie dann über die Kältemaschine wieder gekühlt werden kann. Damit ergibt sich ein Kühlluftkreislauf. Die Einlässe E1 bis En und die Auslässe A1 bis An können jeweils im Regalbereich zwischen zwei Lagerebenen untergebracht sein.This is done in that cold air is blown in from a refrigeration machine (not shown for clarity) via inlets E1 to En at the foot of the bearing, as indicated by small arrows in the illustration, and that the cold air is discharged from the storage area via outlets A1 to An is, whereby it can then be cooled again via the refrigerator. This results in a cooling air circuit. Inlets E1 to En and outlets A1 to An can each be accommodated in the shelf area between two storage levels.

Sofern ein Lager als Stollenlager ausgebildet ist, sollte der Stollen mit den Kommissionierern sich oberhalb der Übergangszone befinden. Die gekühlte Ware würde dann jeweils über die Regalbediengeräte im Stollen temporär bereitgestellt.If a warehouse is designed as a gallery store, the gallery with the order pickers should be located above the transition zone. The cooled goods would then be temporarily made available via the storage and retrieval machines in the gallery.
