Description

The present disclosure relates to a mobile shelving assembly having a plurality of mobile shelving. The disclosure also relates to a method for operating such a mobile shelving arrangement. Finally, the disclosure also relates to an intralogistic distribution center with such a mobile racking arrangement.

Different storage systems are used in intralogistics. Previously known exemplary storage systems include, for example, floor storage (shelf-less), satellite rack storage, and mobile rack storage.

In a floor storage facility, the goods (with or without load carriers) are stored directly on the floor. This type of storage is associated with a high consumption of space. The storage units can be stacked several times and arranged in a compact block (with or without intermediate aisles), for example. No shelves are used in the floor storage.

Alternatively or in addition, shelves can be used to store the stored goods. The stored goods are stored in fixed shelves and are no longer moved until a retrieval process. In this case, it is a static shelf storage.

A special type of static rack storage is the satellite rack storage system. In a satellite rack storage system, the rack levels are designed as storage channels in which the goods are stored several times deep and are retrieved again according to the LIFO principle (LIFO = last in first out). In the 4A (Source: Handbuch Logistik, Springer Verlag, 3rd edition, 2008, p. 651) an exemplary satellite shelf warehouse is shown in perspective. The 4B (Source: see above) shows a schematic front view of some of the storage channels of the 4A .

The storage channels are accessed via rail-guided storage and retrieval vehicles (cf. 4B) also known as satellite vehicles. One or more satellite vehicles can be used at the same time. These satellite vehicles run on rails attached to the side, which are arranged in a lower area of the storage channels. The satellite vehicles can remain permanently in the storage channel or by means of a storage and retrieval unit that can be moved outside the channels (cf. 4A) can be implemented between different storage channels and shelves.

The satellite vehicle represents an autonomous vehicle with a low overall height that can be moved freely along the storage channel in the storage channel below the stored goods. The satellite vehicle is equipped with a lifting device and can load and unload the stored goods independently.

Cross member of the shelf (cf. 4A) have two horizontally oriented surfaces (cf. 4B) . The upper surface serves as a standing area for the stored goods (e.g. pallets). The lower surface serves as a running surface for the satellite vehicles. The satellite vehicles are inserted into the storage channels at the front. The satellite vehicles can move the stored goods in the longitudinal direction (of the channel) within the storage channel.

Another type of storage is the mobile racking system mentioned above. An exemplary mobile racking system is in the EP 1 447 354 A1 disclosed.

The document DE 94 06 352 U1 reveals a sliding shelf.

The document DE 198 46 783 A1 relates to a storage rack for the sorted storage of long materials.

According to the "Logistics Manual" mentioned above, mobile racking systems are generally characterized by the fact that the racks are mounted on a (rail-guided) trolley (sliding carriages) with which the racks can be moved transversely to the racking direction (i.e. transversely to the longitudinal direction of the racks) see. 5A (Source: Logistics Manual). The transfer carriages are usually driven individually. The racks mounted on it are designed according to the respective requirements (of the operator), e.g. as shelf racks, pallet racks or cantilever racks.

The volume is used to the maximum because the shelves can be arranged directly adjacent to one another due to their relative mobility. Before accessing a certain storage location (e.g. a shelf), the neighboring shelves must first be moved in the transverse direction so that a sufficiently wide (shelf) lane is created into which a conveyor (e.g. a forklift, crane or hand truck) drives can. The time for moving the rack blocks essentially determines the storage / retrieval time. With an increasing number of shelf blocks, the amount of movement also increases, so that the access time increases. To avoid uneconomical waiting times, it is therefore advisable to plan several aisles that can be opened dynamically.

In practice, a ratio of approx. 8 to 10 shelves per shelf aisle has proven itself. Usually the two outer shelves are permanently installed, ie the outer shelves cannot be moved. At Larger shelving systems also have additional shelf blocks permanently installed in order to enable the warehouse to be divided up and safe parallel operation of the storage areas created (cf. 5B , Source: Handbuch Logistik).

The overall height of the mobile racking system is limited by the load capacity of the (hall) floor, the design of the sliding carriages and safety regulations. The overall height of the shelf is usually not greater than four times the width of the shelf in order to reduce the risk of tipping over.

Despite the positive volume utilization rate, the storage times (incoming goods) and retrieval times (outgoing goods) are high, so that throughput (number of storage / retrieval per unit of time) in mobile racking systems is relatively low.

The throughput is reduced in particular in cases where there are no areas for interim storage of the goods on the floor in the goods-in area, in the storage area or in the goods-out area. In incoming goods, for example, the stored goods must all be transferred from a delivery vehicle directly to the storage area, for which purpose the one or more rack aisles must be opened for storage. During this time, the aisles cannot be opened for other purposes, for example to remove stored goods for order picking.

The same goes for outsourcing. While goods that have already been stored are being removed, the rack aisles cannot be opened for storage.

It is therefore an object of the present disclosure to provide an improved mobile shelving assembly, an improved system for operating a mobile shelving assembly, and an improved distribution center having such a mobile shelving assembly.

This object is achieved by a mobile shelving arrangement with several shelves, which are arranged parallel to one another along a longitudinal direction, in particular their longitudinal direction, each of the shelves for storing and retrieving stored goods in a transverse direction, which is oriented perpendicular to the longitudinal direction, via a shelf aisle, which is formed by moving two directly adjacent shelves apart in the transverse direction, wherein at least one of the adjacently disposed shelves is movable in the transverse direction, and wherein at least one of the shelves has a buffer channel which is oriented along the longitudinal direction and which is set up to receive a satellite vehicle, which is set up to move the stored goods in the longitudinal direction, within the buffer channel and to store and remove the stored goods in the longitudinal direction via an end face of the at least one shelf.

In the present case, a conventional mobile racking arrangement is expanded to include the functionality of a satellite racking system, by replacing a conventional racking level with at least one storage channel (buffer channel) or adding the buffer channel in at least one of the shelves. It does not matter whether the shelf of the mobile shelving arrangement is a fixed shelf or a movable shelf.

The buffer channels are preferably installed in fixed shelves, because the addition of additional components (more massive beams, accumulation conveyors, gravity trains, satellite vehicles, etc.) increases the load.

The storage in the buffer channels and the removal from the buffer channels is preferably carried out via the front side of the corresponding shelves, so that it is not necessary to open a laterally adjacent shelf aisle. The stored goods can thus be stored and retrieved while the mobile racking arrangement continues to operate normally. The mobile shelving arrangement can, for example, continue to open any aisles in order to process removal orders (picking orders). The goods to be stored or removed from storage temporarily buffered in the buffer channels can be finally stored or removed if no other action is currently to be carried out in the mobile racking arrangement. The traffic within the shelf arrangement can be leveled over time.

This makes it possible, for example, for delivery vehicles to be unloaded immediately in the incoming goods area and for the goods to be stored to be stored temporarily in the mobile racking arrangement. Floor storage areas between the incoming goods area and the mobile racking arrangement are omitted, so that building costs are reduced due to less space being used.

The same applies, of course, to outsourcing in the direction of goods issue. Goods to be retrieved can be collected in advance in a buffer channel and then finally retrieved via its front side.

The at least one shelf that has the buffer channel is preferably a fixed, immovable shelf that is arranged in particular in the transverse direction on the outside in relation to the remaining shelves.

The integration of the buffer channel in a fixed shelf enables the subsequent installation of a buffer channel in an existing system. The buffer channel can therefore be retrofitted.

Since the buffer channel places higher demands on load capacity and stability, the fixed shelves are preferred because they do not have any sliding carriages that additionally limit the load capacity and stability.

The fixed shelves are preferably arranged in the outer areas of the mobile shelving arrangement, because the shelves usually do not have to be moved there in order to open an access alley (shelf alley).

In a particular embodiment, the mobile shelving arrangement comprises at least one satellite vehicle.

The satellite vehicle is then an integral part of the mobile racking arrangement, so that the additional function (temporary storage in the buffer channel) is ensured at all times.

A single satellite vehicle can be sufficient to service multiple buffer channels by moving the vehicle. The storage from an incoming goods department and the retrieval into an outgoing goods department are often separated in time, so that only a few satellite vehicles are sufficient to ensure the desired additional functionality. This particularly reduces the acquisition costs.

Each of the shelves preferably has a plurality of shelf levels one above the other, the buffer channel in particular being arranged in a highest shelf level.

The arrangement of the buffer channel in the highest shelf level has the advantage that no components relevant to the shelf statics impede the continuous use of the buffer channel. Otherwise these have to be replaced by alternative, more complex designs.

It is also advantageous if the at least one of the shelves has a plurality of buffer channels one above the other.

This increases the interim storage capacity.

In particular, several of the shelves each have at least one buffer channel.

This measure also increases the capacity for temporary storage. Path optimization is also possible in this way.

Furthermore, several buffer channels can be operated at the same time, which enables the simultaneous use of several vehicles or operators. This in turn increases flexibility and reduces storage / retrieval times.

In a further special embodiment, two of the shelves each have a buffer channel, the buffer channel of one of the two shelves being used exclusively for the temporary storage of delivered goods and the buffer channel of the other of the two shelves being used exclusively for the consolidation and temporary storage of goods to be delivered.

With this measure, incoming and outgoing goods processes are clearly separated from each other. The processing of the goods receipt and the processing of the goods issue is possible simultaneously and independently of each other.

The stored goods are preferably provided, in particular exclusively, on pallets and stored and retrieved.

The above-mentioned object is also achieved by a method for operating a mobile rack arrangement, the mobile rack arrangement comprising a plurality of racks arranged parallel to one another in a longitudinal direction and the method comprising the steps of: transferring a stored item, in particular directly from an incoming goods area, to a first of the Shelf, which has a buffer channel oriented in the longitudinal direction, in that the delivered storage goods are introduced into the buffer channel in the longitudinal direction via an end face of the first shelf and converted in the longitudinal direction within the buffer channel by a satellite vehicle which can be moved within the buffer channel; Removing the transferred storage goods from the buffer channel in the longitudinal direction over the front side or in the transverse direction over an aisle between the first shelf and a shelf directly adjacent to the first shelf, which is achieved by moving one or more of the shelves in a transverse direction that is perpendicular to Is oriented longitudinally, is opened; Moving the removed storage goods into a second of the shelves by opening a shelf aisle between the second shelf and a shelf directly adjacent to the second shelf and by storing the removed storage goods in the transverse direction in the second shelf via the shelf aisle; Storing the stored goods in the second shelf; Removal of the stored goods from the second shelf in the transverse direction via a shelf aisle between the second shelf and a shelf directly adjacent to it; and delivering the stored goods, in particular directly, to a goods issue.

Here, too, it becomes clear again that a rack aisle does not necessarily have to be opened for temporary storage of goods to be stored and retrieved. The goods to be stored and retrieved can be stored and retrieved via the front side (s) of the shelves, which are provided with the buffer channels. This results in a corresponding time saving.

It is therefore advantageous that the delivered storage goods are transferred without opening a rack aisle.

The object is also achieved by a distribution center with a mobile racking arrangement, the distribution center furthermore having: a goods receiving area, where goods to be stored are delivered; an outgoing goods department, where stored goods are delivered; and a warehouse where the mobile shelving assembly is located; Incoming goods, outgoing goods and the warehouse are free of floor storage.

The distribution center requires little space, since in particular there is no need for the floor storage facility for interim storage of goods to be stored and retrieved. Thus, the building costs are reduced. The operating costs of the building are also reduced accordingly.

It is also advantageous if the distribution center is used for handling frozen goods, because only the warehouse is to be arranged in a deep-freeze area.

This measure also reduces the operating costs and the investment costs. The parts of the distribution center that need to be cooled, i.e. the warehouse, are only cooled. A cooling of the incoming and outgoing goods is not necessary, since the frozen stored goods can be transported directly from the warehouse to the incoming and outgoing goods or the delivery vehicles waiting there without interrupting the cold chain and being parked in the incoming / outgoing goods area.

It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively specified combination, but also in other combinations or alone, without departing from the scope of the present invention.

Exemplary embodiments of the invention are shown in the drawings and are explained in more detail in the following description. Show it:

• 1 a schematic layout (top view) of a distribution center with a mobile shelving arrangement according to the present disclosure;
• 2 a schematic view of a shelf shown in isolation according to the mobile shelving arrangement 1 ;
• 3 a flow diagram of a method for operating a mobile shelving arrangement;

1 shows a layout (top view) of a general intralogistic storage and picking system, which is specially designed as a distribution center. There are various stored goods 24 delivered, stored and put together according to picking orders and then delivered.

The distribution center 10 assigns a warehouse 12 , a goods receipt (WE) 14th and a goods issue (WA) 16 on. The warehouse 12 , the incoming goods 14th and the goods issue 16 provide (spatial) areas within the distribution center 10 that are equipped with suitable facilities (e.g. loading ramps, gates, etc.) that enable the corresponding intralogistic function (storage, goods receipt, goods issue, order picking, etc.) to be carried out.

In the 1 these three functional areas are exemplarily separated from one another by dashed lines, with the bearing 12 is shown on the left and the incoming goods 14th and the goods issue 16 right (one above the other) in the 1 are shown. It goes without saying that this separation, in particular with regard to dimensioning, can be changed as desired.

The warehouse 12 is usually much larger than incoming goods 14th and the goods issue 16 dimensioned. The incoming goods 14th and the goods issue 16 could for example also be implemented in the same area. Furthermore, it goes without saying that further intralogistic functional areas (not shown here) can be provided, such as, for example, picking stations, receipt stations, control stations and the like (not shown).

The spatial boundaries between the camp 12 , the incoming goods department 14th and outgoing goods 16 are only defined by a building, not specified here, in which the distribution center 10 is realized. It goes without saying that incoming goods 14th eg also in the longitudinal direction X opposite the goods issue 16 can be arranged with the bearing 12 would be arranged in between.

The warehouse 12 essentially has a mobile shelving arrangement 18th on that in the 1 is outlined with a dash-dotted auxiliary line for illustration. The mobile shelving arrangement 18th has several shelves 20th on. In the 1 are exemplary seven shelves 20th shown. More or fewer shelves can be provided. The shelves 20th are in their longitudinal direction X, those with the longitudinal direction of the distribution center 10 coincides, arranged parallel to each other. At least some of the shelves 20th are movable in their transverse direction Z, which is oriented perpendicular to the longitudinal direction X. Preferably all shelves are 20th Movable in the transverse direction Z (motorized and autonomous).

Between the shelves 20th can have one or more (shelf) aisles in the Z direction 22nd be formed by at least some of the shelves 20th are moved apart in the transverse direction Z. In the 1 are two alleys as an example 22-1 and 22-2 shown.

2 Figure 11 shows a perspective view of a shelf shown in isolation 20th the 1 . The shelve 20th the 2 is illustrated schematically as a shelf block, which is divided in the vertical Y direction into, for example, three shelf levels RE1-RE3. It goes without saying that more or less shelf levels RE can be provided. The shelving levels RE are used to store goods (not shown) 24 (see. 1 ). The following are examples of stored goods 24 considered the (single type) on pallets 25th (see. 1 ) are stacked. The shelves are accordingly 20th , in particular their longitudinal and transverse beams (not shown) for storing pallets 25th furnished. It goes without saying that other load carriers (e.g. containers, trays, cardboard boxes or the like) can also be used.

Returning to 2 it concerns the shelves 20th around storage facilities that extend essentially in the longitudinal direction X. The shelves 20th have a width in the transverse direction Z that is suitable for single-deep or multiple-deep storage of the stored goods 24 is set up. In the example of 1 and 2 become the pallets 26th simply stored deep.

The shelves 20th can be designed to be fixed or movable by a motor. In the 2 is a solid shelf 20th shown because a (unspecified) transfer car in the 2 not shown is that of movable shelves 20th is provided below the lowest shelf level RE1 and includes all components (such as motors, chassis, wheels, controls, etc.) that are used to move the movable shelves 20th required are.

At least one of the shelves 20th the mobile shelving arrangement 18th assigns a buffer channel 26th on. In the 2 is the buffer channel 26th arranged in the lowest shelf level RE1. It goes without saying that the buffer channel 26th on any shelf level RE can be arranged. It is also understood that each of the shelves 20th one or more of the buffer channels 26th (vertically one above the other and / or horizontally next to one another). However, it can be for the distribution center 10 the 1 be sufficient if only one of the shelves 20th a single buffer channel 26th (on any shelf level RE ) having.

The arrangement of the buffer channel 26th takes place preferably in the top shelf level RE3, because no components relevant to the shelf statics hinder the continuous use of the buffer channel. The stored goods 24 are made by a simple movement in the longitudinal direction X over one of the (narrow) end faces 28 on the appropriate shelf 20th transferred.

The front sides 28 represent end faces that are in the YZ plane at the ends in the longitudinal direction X of the shelves 20th extend. Each of the buffer channels 26th is generally set up on the front side 28 of its corresponding shelf 20th with the stored goods 24 to be taken care of. For this purpose it is not necessary to have the shelves 20th to open an alley 22nd are moved apart in the transverse direction Z. The supply of the buffer channels 26th can be done solely on the front sides 28 be done without the shelves 20th be moved in the transverse direction Z.

In the 1 can use the buffer channels 26th only on the end faces on the right 28 operated from the front (LIFO principle). It goes without saying that with appropriate relative positioning of the shelf arrangement 18th also a frontal supply over the left frontal sides 28 (LIFO principle) or via the left and right front sides 28 can take place simultaneously (FIFO principle).

The buffer channels 26th are set up one or more satellite vehicles 30th with lifting function for lifting and lowering the pallets 26th record in the Y direction. In particular, several satellite vehicles can 30th within the same buffer channel 36 can be used. The satellite vehicles 30th are known. A satellite vehicle 30th is exemplary in the 4B shown. The Satellite vehicles 30th are lengthways in the buffer channels 26th movable on rails, as in the prior art.

The buffer channels 26th in particular have longitudinal members with corresponding cross-sections that enable storage of the pallets 25th on their top and a driving satellite vehicles 30th enable on their underside, as is already known from the prior art.

It goes without saying that (from the outside) also in the transverse direction Z on the buffer channels 26th can be accessed, in which case an adjacent lane 22nd must be open.

In the 1 there are also two exemplary conveyors (e.g. forklifts) 32 shown the stored goods 24 between the camp 12 , the incoming goods department 14th and outgoing goods 16 move automatically. The conveyors 32 move the stored goods 24 also within the warehouse 12 . Alternatively or in addition, you can also edit manually.

It goes without saying that more or less conveyors 32 can be used. The conveyors 32 can be operated without a driver.

The conveyors 32 are set up, the stored goods 24 from incoming goods 14th into the warehouse 12 and vice versa from stock 12 to goods issue 16 to transfer. The conveyors 32 are also set up, the stored goods 24 and the satellite vehicles 30th over the front sides 28 into the buffer channels 26th to be stored in the longitudinal direction X and out of the buffer channels 26th swap out in the longitudinal direction X. The conveyors 32 are also set up the stored goods 24 in the transverse direction Z over the alleys 22nd on the shelves 20th , and especially in the buffer channels 26th , store and outsource.

In the 1 is the conveyor 32-2 inside the alley 22-2 shown to stored goods 24 in the transverse direction Z with one of the shelves 20th to exchange the one directly adjacent to the open alley 22-2 is arranged.

In the 1 are exemplary the two outer shelves 20th the mobile shelving arrangement 18th each with a buffer channel 26th Mistake. The conveyor 32-1 has the buffer channel 26th of the upper, external shelf 20th already completely over its (not specified here) end face 28 with stored goods 24 filled.

The conveyor 32-2 is in an outsourcing situation for the lower outer shelf 20th shown. The alley 22-2 it is open. The conveyor 32-2 has stored goods 24 from the lower buffer channel 26th taken. The lower buffer channel 26th is not completely filled. The conveyor 32-2 brings the removed stored goods 24 in the goods issue 16 to get there (preferably directly) in a waiting truck 34 to be loaded.

Both the incoming goods 14th as well as the goods issue 16 are set up several trucks 34 to supply, ie to load and unload at the same time. Loading docks, gates and the like are in the 1 Not shown.

Preferably the two outer shelves 20th that are the buffer channels 26th in the 1 have fixed shelves 20th that are immobile. The rest of the shelves 20th between these two outer shelves 20th can all be designed to be movable. The ones in the 1 Exemplary mobile shelving arrangement shown 18th is designed so that the two shelf aisles 22-1 and 22-2 can be opened at the same time.

Although the alley to the upper buffer channel 26th is not open, the conveyors can 32 nevertheless over the front side 28 in the upper shelf 20th storage and retrieval. Thus, in the open streets 22-1 and 22-2 can be worked in parallel to the storage process. The same is of course true for an outsourcing process, assuming that at least one of the buffer channels 26th in advance (e.g. at times of low utilization) with such stored goods 24 which belong to a delivery order.

In both cases (storage and retrieval) the buffer channels 26th parallel to regular work in the warehouse 12 filled or emptied. In the case of an outsourcing process, the corresponding buffer channel 26th for example in advance with such stored goods 24 via a neighboring alley 22nd in the transverse direction Z or over the corresponding face 28 be filled in the longitudinal direction, which were previously removed from the other (storage) shelves 20 by a corresponding aisle 22nd opened. Of course, this also applies to the storage process in which the stored goods are to be stored 24 on the (storage) buffer channel 26 either in the longitudinal direction X over its end face 28 or via an adjacent open alley 22nd stored in the cross direction Z and in a final storage rack 20th be moved.

A particularly advantageous application relates to the handling of frozen goods 24 . Frozen stored goods 24 are to be handled in areas that are frozen. In particular, the camp must 12 be frozen.

Since deep freezing is extremely costly and energy-intensive, the corresponding Freezer areas geometrically dimensioned as small as possible.

This means that the goods receipt 14th and the goods issue 16 and the camp 12 merge smoothly, so that the frozen stored goods 24 straight off the shelves 20th according to a picking order or a removal order directly into the corresponding truck without intermediate storage in a floor storage facility 34 can be transferred. The same applies of course to frozen goods to be stored 24 straight from the truck 34 into the assigned buffer channel 26th be transferred.

The warehouse is special for deep-freeze applications 12 , the incoming goods 14th and the goods issue 16 floor storage free. This means that the surfaces of the warehouse 12 , the goods receipt 14th and the goods issue 16 are chosen so small that the frozen goods to be stored and retrieved 24 not on the ground on their way between the trucks 34 and the shelves 20th can be turned off.

The building in which the deep-freeze warehouse 12 is provided, so can be designed smaller. The operating costs (for example for cooling) are drastically reduced.

The buffer channels 26th for the satellite vehicles 30th can be retrofitted in existing shelf arrangements, especially in fixed shelves 20th which in turn is part of an existing mobile shelving arrangement 18th could be. No floor space is required.

3 FIG. 3 shows a flow diagram of a method for operating a mobile shelving arrangement 18th as exemplified in the 1 is shown.

In a first step S10, the stored goods 24 in a first of the shelves 20th , which has a buffer channel oriented in the longitudinal direction X. 26th has, transferred by the delivered goods 24 in the longitudinal direction X over the face 28 of the first shelf 20th into the buffer channel 26th introduced and from one inside the buffer channel 26th movable satellite vehicle 30th in the longitudinal direction X within the buffer channel 26th is implemented. The stored goods 24 are especially taken directly from the incoming goods department 14th provided.

In a further step S12, the transferred storage goods 24 in the longitudinal direction X over the face 28 , or alternatively in the transverse direction Z via a rack aisle 22nd between the first shelf 20th and one to the first shelf 20th directly adjacent shelf 20th by adding one or more of the shelves 20th in the transverse direction Z to the opening of the shelf aisle 22nd are proceeded.

In a step S14, the stored goods are removed 24 on a second shelf 20th moved by a shelf aisle 22nd between the second shelf 20th and one to the second shelf 20th directly adjacent shelf 20th is opened and the removed stored goods in the transverse direction Z in the second shelf 20th across the Regalgasse 22nd is stored.

In a further step S16, the stored goods 24 on the second shelf 20th stored.

In a step S18, the stored goods 24 from the second shelf 20th in the transverse direction Z over one of the shelf aisles 22nd between the second shelf 20th and the directly adjacent shelf 20th outsourced. After that, the stored goods are stored 24 especially directly to the goods issue 16 submitted.

It goes without saying that the transferring, removing, moving, retrieving and / or dispensing can be carried out automatically or manually. In the case of an automated implementation, industrial trucks (forklifts, autonomous driverless transport vehicles, etc.) are used in particular.

As an alternative or in addition to the satellite vehicle buffer channels described above 26th could use the buffer channels 26th be equipped with actively driven accumulation conveyors and / or with passive gravity conveyors. It is important that the temporarily stored goods 24 stay at a controlled distance to allow individual access to the temporarily stored goods (via the aisle 22nd and also over the front side (s) 28 ) to enable.
