For example, the published patent application DE 32 07 860 A1 , which is probably the closest prior art, a conveyor for a warehouse facility comprising a plurality of high shelves, which are set up in rows. Between the rows, a undercarriage, which carries a carrier piggyback, move and send the carrier car on channels of the shelves in the shelves to fetch cargo from the shelves. The undercarriage can be driven together with the carrier car and the piece goods in an elevator and transported by this between the floors and a transfer station.

The invention has for its object to propose a high-bay warehouse and components thereof and a corresponding method, which allows an automated and / or efficient storage of cargo.

This object is achieved by a high-bay warehouse with the features of claim 1, by a stacker crane with the features of claim 9, by a tandem shuttle with the features of claim 11, by a transfer shelf with the features of claim 15 and by a method with the features of Claim 18 solved. Preferred or advantageous embodiments of the invention will become apparent from the dependent claims, the following description and the accompanying drawings.

In the context of the invention, a high-bay warehouse is proposed, which is suitable for storage of pallets and / or formed. The pallets can in principle have any shape, thus z. B. as loaded pallets, general cargo on pallets, pallet container with pallet sections or pallet cargo with pallet sections or pallet lattice boxes with pallet sections. The pallet section of the pallet permits automated picking and / or automated manipulation, for example by a forklift or by an automated system, such as a robot or a stacker crane device.

The high-bay warehouse has a plurality of high shelves, which are set up in rows, so that arise between the rows of aisles. These can be separate high shelves, interconnected high shelves or a superstructure with several shelves as sections. The rows are preferably formed parallel to each other, in modified embodiments, other configurations, such as star-shaped alignments, can be realized.

In the high shelves bearing channels are formed in each of which at least one pallet can be stored. Usually, a plurality of pallets, for example 3, 4, 5, 6 or more pallets, can be stored in a storage channel in a storage direction. The bearing channels can also be referred to as multi-deep. Preferably, the bearing channels extend perpendicular to the orientation of the gears and / or the alignment of the rows. In the high shelves at least two storage channels are arranged in different levels one above the other. Preferably, more than three storage channels, in particular more than 5 and in particular more than 8 storage channels in different levels one above the other, in particular vertically above one another, arranged.

The high-bay warehouse includes a rail system having a channel rail area extending in the storage channels and, as will be introduced later, in buffer channels, and having a gangway area extending in the corridors. Preferably, the rail system runs in the various, especially in all levels of the high-bay warehouse.

The high-bay warehouse further comprises at least one tandem shuttle, which can be divided into two components. A gang carriage is designed to travel on the gang rail area, a channel car is designed to travel on the channel rail area. The task of the channel wagon is to store and / or outsource a pallet in a channel, in particular a bearing channel or buffer channel. The task of the gang carriage is to optionally carry the channel cart with the loaded pallet in the gangway area. For this, the gang carriage preferably piggybacks the channel car.

A vertical transport device is configured to allow transport of the tandem shuttle and / or the pallet from a first level to another, second level. Preferably, the tandem shuttle may optionally be transported with a loaded pallet or without a loaded pallet. In particular, the high-bay warehouse, in particular the vertical transport device, is designed to transport the pallet without the tandem shuttle.

In the context of the invention, it is proposed that the vertical transport device is designed to be movable along one end side of the rows and / or along the front side of one or more of the aisles. Thus, the vertical transport device is designed to transport at least one pallet and / or at least one of the tandem shuttle in a direction perpendicular to the longitudinal extension of the aisles and / or the rows.

This expansion of freedom of movement for the vertical transport equipment in connection with the concept of a tandem shuttle in a high-bay warehouse opens up new possibilities for strategies for storing and retrieving pallets in high-bay warehouses:
In a first possible embodiment of the invention, the vertical transport device allows the transport of the at least one tandem shuttle and / or the at least one pallet from a first gear or gear range to a second gear or gear range. The gangway is understood in particular to mean the gangway with the adjacent rows of high-level shelves and / or open in the direction of the aisle.

In this first and possibly simplest embodiment, a vertical transport device and a single tandem shuttle are sufficient for a high-bay warehouse to be able to store and remove all storage bins. In order to increase the capacity and the storage speed, further tandem shuttles or vertical transport equipment can be added depending on the requirements. In exemplary constellations only one vertical transport device and several Tandemshuttles be used in a high-bay warehouse. Also, any other number ratio between vertical transport facilities and Tandemshuttles is possible.

In particular, this embodiment has the advantage that the high-bay warehouse is scalable, so that initially only a few vertical transport facilities or tandem bays are used in the case of a low capacity requirement and further facilities can be added with increasing capacity requirements.

In a preferred embodiment of the invention, the high-bay warehouse comprises at least one transfer shelf, wherein the transfer shelf is arranged as a buffer storage between the high shelves and / or the storage channels on the one hand and the vertical transport device on the other hand logistically and spatially. The transfer shelf has buffer channels, which are preferably aligned parallel to the storage channels, and in each of which at least one pallet can be stored in a buffer position. Again, it is preferred that at least 3, 4, 5, 6 or more pallets are successively storable in buffer positions in a buffer channel. Preferably, the transfer shelf has buffer channels in each plane, which also includes storage channels. The buffer channels serve in their respective level as buffer storage for pallets, which are to be stored or which are to be outsourced. Particularly preferably, at least two buffer positions for storage pallets and at least two buffer positions for removal pallets per level are reserved.

In a preferred embodiment of the invention, the vertical transport device is designed for a transport and / or transfer of the at least one pallet to at least one, preferably to a plurality, any buffer positions in a plane. The vertical transport device thus uses the degree of freedom with respect to the movement along the end face, to store pallets randomly in buffer positions and / or pick up from buffer positions.

Thus, the possible functional width of the vertical transport device is extensive, since pallets and optionally tandem buses can be transported from one gear or gear range to another gear or gear range and / or to any buffer positions in a plane of a gear or aisle area.

It is preferred that the high-bay warehouse is designed so that the at least one pallet can be transported through the channel trolley and through the vertical transport device into the buffer position of the transfer rack. Thus, the buffer position represents a transfer position, wherein the pallet can be delivered by the vertical transport to the buffer position and picked up and can also be delivered or picked up by one or the channel carriage to the buffer position. With this configuration, it is thus possible for a storage that a pallet is stored by the vertical transport to an arbitrary buffer position in the transfer shelf, is picked up from there by the channel carriage, the channel car is transported to the pallet by means of the gang carriage along the aisle and then is stored again by means of the channel wagon in a storage channel in the same plane. The collection or removal of a pallet can be done in reverse order.

In a practical development of the invention, the high-bay warehouse on a conveyor, for example a conveyor belt, a conveyor cross, etc., wherein the vertical transport device is designed for transferring pallets to the conveyor and / or for accepting pallets from the conveyor. In this constructive configuration, the vertical transport device can thus pick up a pallet to be stored from the conveyor and store it via the tandem shuttle or pick up a stored pallet with the aid of the tandem shuttle and transfer it to the conveyor.

In a very simple embodiment of the invention, the vertical transport device is designed as a forklift and / or a rail-free and / or wegebundenes device. In this case, the high-bay warehouse is realized as a semi-automatic high-bay warehouse. In a preferred embodiment of the invention, however, the high-bay warehouse is embodied as an automatic high-bay warehouse, wherein the vertical transport device is designed as a stacker crane. The storage and retrieval unit is preferably tied away, in particular rail-bound, with the rails or the path definition running along one or more end faces of the rows. The storage and retrieval unit is designed as a robot device which z. B. is controlled via a central host, which preferably also controls the or the Tandemshuttles.

Thus, the high-bay warehouse represents as an automated device, which is controlled by a host computer or a host computer system that controls the conveyor, the or the stacker cranes and the tandemshuttles or the.

Due to the possibility that the stacker cranes move on the front sides of the rows of shelves and possibly change from one aisle area to a next aisle area, the number of stacker cranes is independent of the number of aisles. Likewise, the number of Tandemshuttles is independent of the number of stacker cranes and the aisles. As already explained, the smallest configuration is provided by at least one storage and retrieval unit and at least one tandem shuttle, which can jointly serve all rows of shelves of the high-bay warehouse.

Another object of the invention or a development of high-bay warehouse relates to one or the stacker crane, which is suitable and / or designed for the high-bay warehouse described above. In particular, the high-bay warehouse may have at least one of the stacker cranes described below.

In this subject matter, it is provided that the storage and retrieval unit has an actuator system for taking over and / or transferring pallets and / or tandem shuttles from a buffer or storage position. The special feature of the storage and retrieval unit with the actuator system is that it can be moved along an end face of the rows and / or the aisles and / or that it is designed to transport the tandem shuttle.

The possible functions of the stacker crane are thus to transport the tandem shuttle and / or the at least one pallet in the vertical direction, that is to say from a first plane to a second plane, and / or in a horizontal direction from a first gear or gangway to transport a second gear or gear range and / or to transport from a first to a second buffer position of the same gear range or another gear range and / or to transport to the conveyor or in the opposite direction.

Another object of the invention or a development of the invention relates to a tandem shuttle, which is suitable and / or designed for the high-bay warehouse, as described above. The tandem shuttle thus forms an independent subject of the invention or a Development of the invention. Thus, the tandem shuttle can also be used for other high-bay warehouse.

It is envisaged that the gang carriage and / or the channel carriage together or in each case has or have a self-sufficient and / or entrained energy source. As a result of this configuration, it is possible to dispense with an extensive energy supply, which otherwise would have to be routed parallel to the rail system, in the rail system and thus simplifies the construction of the high-bay warehouse.

Particularly preferably, the energy source of the gantry is designed as a short-term energy source, which is designed so that it is sufficient for less than 10 minutes, preferably less than 8 minutes, in particular less than 5 minutes travel time at a travel speed of 3 m / s. Alternatively or additionally, the energy source of the channel trolley is designed as a long-term energy source, which allows more than 7 hours of driving time, preferably more than 10 hours of driving time and in particular more than 17 hours driving time of the canal trolley.

This embodiment is based on the idea that the short-time energy source is charged every time or as needed when the gang carriage is turned off in the transfer shelf at short notice. During the waiting period required by the channel wagon to load or unload a pallet, the gang carriage is charged. In contrast, the energy source of the channel car is preferably designed as a long-term energy source, which, for example, only once per layer, per double layer or per day must be loaded.

In a practical embodiment of the invention, the energy source of the gang carriage as at least one SuperCap (capacitor) and / or the power source of the channel trolley is formed as an accumulator. The SuperCap is characterized by a very short loading time, so that the waiting time in the transfer rack is sufficient for a loading process, without hindering the transport flow. Preferably, the total capacity of the or the super cap of the gang carriage is greater than 1 Farad, in particular greater than 3 Farad formed.

So that the tandem shuttle can be transported by the vertical transport device, it is preferred if this has a mechanical interface, in particular longitudinal ribs, which is designed such that the vertical transport device can receive the tandem shuttle from the gear rail area in a gear direction and / or a retraction of lifting devices in the direction of travel of the gang car is possible. The mechanical interface thus allows the vertical transport device to pick up the tandem shuttle and transfer it to another plane or another gear. Preferably, the mechanical interface is designed like a pallet section.

Another object of the invention or a further embodiment of the invention relates to the transfer shelf, wherein this is formed so that the buffer positions represent transfer areas, which can be supplied by both the vertical transport device and by the channel carriage with pallets. Practically implemented can be provided that in the bearing channels for guiding the wheels of the channel car C-profiles are provided, which surround the wheels above, below and laterally. In addition, the pallets are deposited on top of the C-profiles. However, these C rails would form an interference contour when taking over the pallets by the vertical transport device, so that instead L-profiles, which support the wheels from below and to the side, are preferred instead.

In a further development or an alternative of the transfer rack is provided to arrange a charging station for the power source of the gangway at a parking position of the gangway area, a charging station for the energy source of the gangway and / or at a parking position of the channel rail area a charging station for the energy source of the channel car. Particularly preferably, one or both of the charging stations is designed for contactless charging of the energy source of the channel wagon or gang carriage.

In one possible embodiment of the invention, the parking position is arranged in each case at one end of the gear rail area or of the channel rail area.

Another object of the invention relates to a method for storing and / or retrieval of pallets in a high-bay warehouse, preferably the high-bay warehouse, as described above, wherein during storage, the vertical transport means transfers the pallet to the tandem shuttle, optionally with the interposition of the transfer shelf and the tandem shuttle the Storing pallet in a pre-tuned storage channel and / or outsourcing the pallet shuttle from the high bay during removal and then optionally the vertical transport device is transferred with the interposition of the transfer rack, wherein the vertical transport device is formed, the pallet and / or the tandem shuttle along an end face of the rows method.

Further features, advantages and effects of the invention will become apparent from the following description of preferred embodiments of the invention and the accompanying drawings. Showing:

The 1 shows in a highly schematic plan view from above a high-bay warehouse 1 which has a plurality of rows 2 with shelves 3 includes. The rows 2 are through passages 4 separated from each other. In every shelf 3 For example, there are four or five bins 6 arranged, the storage channels 7 form, which are perpendicular to the corridors 4 are arranged. In the presentation in the 1 is only one level of the high-bay warehouse 1 shown every shelf 3 However, it has several levels, with the storage channels 7 and / or the storage bins 6 are arranged one above the other in the horizontal direction.

Such a high-bay warehouse 1 serves to pallets 8th on the storage areas 6 to put in, off or intermediately. In the presentation in the 1 are the empty bins 6 through empty squares and with pallets 8th occupied bins are shown as shaded squares. At the pallets 8th For example, they can be Euro pallets or other palletized piece goods, it is also possible that the piece goods, for example containers, each have a pallet section.

During storage, the pallets are 8th in the warehouse channels 7 introduced, which usually from the end with the pallets 8th be filled. Outsourcing takes place from the side of the aisles 4 the foremost palette 8th one of the storage channels 7 is outsourced.

The high-bay warehouse 1 in the 1 is partially automated and has a tandem shuttle 9 which is on a rail system 10 on the one hand in a corridor area 11 and second, in a canal area 12 is automatically and / or automatically movable. More specifically, the tandem shuttle includes 9 a gang carriage 13 which is in the corridor area 11 and a canal wagon 14 which is in the channel area 12 can proceed. For clarity, the rail system is only in one gear 4 indicated schematically.

The channel cart 14 is designed as a lift truck, which of the gang carriage 13 Piggyback to any warehouse 7 is moved from there, separated from the gangway 13 in the warehouse channel 7 enters, a desired range 8th picks up and together with the palette 8th on the gang car 13 returns. The gang car 13 then moves the loaded channel car 14 to a front side 15 of the high-bay warehouse 1 or the gears 4 or the rows 2 , Here is the palette 8th from a vertical transport device 16 in the 1 is designed as a forklift, taken and driven to a dispensing point, not shown.

In addition, the vertical transport device 16 trained to the tandem shuttle 9 from a first course 4 to a second course 4 to transport. After every level of the high bay warehouse 1 the rail system 10 both in the aisle area 14 as well as in the canal area 12 can be formed with the combination of a tandem shuttle 9 and the vertical transport device 16 any storage bin 6 in the high-bay warehouse 1 with a pallet 8th be supplied.

At a higher throughput it is possible to have several tandem shuttle 9 or more vertical transport devices 16 use.

The 2 shows a development of the high-bay warehouse 1 in the 1 , wherein like reference numerals again designate the same areas or parts. In the embodiment in the 2 is the high-bay warehouse 1 around a delivery shelf 17 added, which instead of stock channels 7 rectified buffer channels 18 each having multiple buffer positions for pallets 8th in an extension perpendicular to the corridors 4 demonstrate. Just like the warehouse channels 7 are the buffer channels 18 on both sides of the adjacent corridor 4 open. In the embodiment in the 2 are the bins 6 on the left side of the assigned corridor 4 used as a buffer for storage and on the right as a buffer for paging. The delivery shelf 17 is designed so that on the one hand the storage bins 6 in the buffer channels 18 through the channel cart 14 with pallets 8th can be operated and the other by the vertical transport device 16 ,

The storage concept thus provides that when storing the vertical transport device 16 pallets 8th in one of the buffer channels 18 stored and the sewer truck 14 this stored pallet 8th picked up and assigned to the storage area 6 in the shelf 3 brings. It must have vertical transport device 16 and tandem shuttle 9 do not work synchronously, but can completely independent of each other, in particular temporally decoupled, the pallets 8th transport. This concept allows, depending on the size of the warehouse, for example, with a vertical transport device 16 two or three tandem shuttle 9 to supply. The tandem shuttle 9 can in this case again by the vertical transport device 16 from a first course 4 to another gear 4 to be brought. Again, as an important concept share provided that the vertical transport device 16 on a front side 15 of the ranks 3 or the handover rule 17 procedures and pallets 8th and / or the tandem shuttle 9 can transport.

The 3 shows a development of the embodiment in the 2 , where the high-bay warehouse 1 now as a fully automated high bay warehouse 1 is trained. Compared to the embodiment in the 2 Instead of the forklift, several storage and retrieval machines are now available as vertical transport facilities 16 provided, for example, on rails along the front side 15 of the handover shelf 17 can proceed. The stacker cranes 16 are trained to use the pallets 8th and if necessary, the tandem shuttle 9 to a conveyor 20 , for example, designed as a conveyor to pass.

In the different gears 4 Different states of storage and retrieval are shown. In the corridor 4 I supplies one of the stacker cranes 16 the delivery shelf 17 with two new pallets 8th for storage, the tandem shuttle 9 transports another pallet 8th for their storage. In the corridor 4 II has the stacker crane 16 the two pallets 8th in the storage area into one of the buffer channels 18 the delivery shelf 17 parked and the tandem shuttle 9 is in the delivery shelf 17 retracted, with the gang carriage 13 standing in a parking position and the channel wagon 14 into one of the buffer channels 18 retracted and there is a pallet 8th to pick up for the storage and retrieval unit 16 settles.

In the corridor 4 III gets the stacker crane 16 two pallets 8th from the buffer channel 18 off, while the channel wagon 14 a pallet from a storage bin 6 in a warehouse channel 7 picks up and with the pallet 8th to the gearbox 13 withdrawal begins.

In the corridor 4 IV drives the freed channel wagon 14 to the gong car 13 back and the stacker crane 16 hands over two pallets 8th to the conveyor 20 ,

While in the embodiment in the 3 every gear 4 its own storage and retrieval unit 16 It is also sufficient if the number of storage and retrieval machines 16 smaller than the number of aisles, so that a storage and retrieval machine several courses 4 must serve.

An extreme case is in the 4 shown, with the fully automatic high bay warehouse 1 only a single tandem shuttle 9 and a single stacker crane 16 having. Also in this embodiment of the invention, the storage and retrieval device takes over 16 the task, the pallets 8th from the conveyor 20 to the delivery shelf 17 to transport, with the stacker crane 16 on the front side over several buffer locations or storage bins in the buffer channels 18 or even over several courses 4 is movable. The tandem shuttle 9 assumes the task of transporting the pallets 8th from the bins into the delivery shelf 17 ,

In the 5 is a schematic side view of a storage and retrieval unit 16 shown, which in front of the front of the transfer shelf 17 stands. The stacker crane 16 has two extension devices 21 on, which allow a palette 8th and / or a tandem shuttle 9 optionally on the conveyor 20 or in the delivery shelf 17 store. In addition, the Ausfahreinrichtungen 21 together with pallets 8th be moved in height, so that the stacker crane 16 every level 1 - 10 of the high-bay warehouse 1 or the handover rule 17 can reach. In the corridor 4 are schematically three tandem shuttle 9 shown in the levels 8th . 9 , and 10 the current transport of the pallets 8th in the corridor 4 take. After processing the orders in the levels 8th - 10 be the tandem shuttle 9 moved to other levels to process further jobs. For example, after processing, that is, the removal of the pallets 8th in the plane 10 , the top tandem shuttle 9 into the plane 1 through the stacker crane 16 be offset. Alternatively or additionally, it is also possible that the tandem shuttle 9 in another gear 4 or moved to another level.

The 6 shows a detail from the high-bay warehouse 1 in the area of the transfer shelf 17 in a highly schematic representation. In the corridor 4 are two L-rails 22 of the rail system 10 in the corridor area 11 to recognize, on which the Gangwagen 13 can proceed. At the end of the corridor area 11 are buffer stops 23 pictured, which is a retraction of the gantry car 13 or the tandem shuttle 9 prevent.

In the warehouse channels 7 are C-rails 24 for the rail system 10 in the canal area 12 provided in which the wheels of the canal wagon 14 to run. In the area of the transfer shelf 17 but are only L-rails 25 in the channel area 12 provided to a penetration of the extension devices 21 into the buffer channels 18 from the front of the transfer shelf 17 to enable. The pallets 8th be in the warehouse canals 7 deposited on top of the C-rails, in the buffer channels 18 are on the other hand support blocks 26 arranged on which the pallets 8th can be turned off.

In the 7 is the same detail area as in the 6 shown but with one in the buffer channel 18 stored pallet 8th , the tandem shuttle 9 as well as a pallet 8th in the warehouse canal 7 ,

The 8th shows a storage process of pallets 8th through the stacker crane 16 in the buffer channel 18 , where the stacker crane 16 with the extension devices 21 the pallets 8th in the buffer channel 18 lifts. On the other side of the aisle 4 is through the channel carriage 13 just a palette 8th stored, the storage and retrieval system 16 to pick up at a later date. The 9 shows the same area in a schematic bottom view, so that the support blocks 26 are covered. In the 10 the relationships are shown in a schematic view from the front. The 11 shows a view from the front of a storage channel 7 , where the C-rails 24 shown from the inside.

The 12 shows a view into the channels 7 . 18 , where on the right side storage channels 7 and on the left side buffer channels 18 are shown. Here are the different rails for the channel areas 12 C rails are used on the right side and L rails on the left side.

The 13 shows a three-dimensional representation of the tandem shuttle 9 , where the gang carriage 13 on the rail system 10 in the corridor area 11 is shown. On the gangway 13 is the channel car 14 piggyback loaded, taking the wheels 30 from the gang carriage 13 and the wheels 31 from the sewer truck 14 are arranged perpendicular to each other.

On the bottom, the gang carriage points 13 L and C profiles 32 on, so that a mechanical interface is formed, over which the Gangwagen 13 with charged channel cart 14 through the stacker crane 16 or the truck 16 can be included. For a transfer of the canal wagon 14 into a canal area 12 shows the gantry 13 two sliding rails 33 which z. B. by means of a toothed shaft in the direction of the channel regions 12 can be moved. The track width of the rails 33 is chosen so that this the track width of the rails in the channel area 12 equivalent. In operation, the rails are 33 proceed so that the channel carriage 14 without annoying gap from the gantry car 13 in the canal area 12 can retract. Furthermore, the channel trolley includes 14 a lifting device that allows a lifting plate 34 to move in a vertical direction, so pallets 8th from the storage areas 6 taken or on the storage bins 6 can be turned off.

The power supply of the gang car 13 takes place by a supercap, which comprises several capacitors as energy storage. The power supply of the canal wagon 14 on the other hand takes place via a battery pack. The tandem shuttle 9 thus indicates the channel carriage 14 and for the gong car 13 each a self-sufficient energy source.

The energy source of the gantry car 13 is designed so that this only for a multiple procedure in the aisles 4 sufficient.

It is intended that the gang carriage 13 in the delivery shelf 17 every time or frequently charged. The 14 shows charging points 35 in the header area of the transfer shelf 17 about which the gantry car 13 is charged as soon as it is parked and on the channel wagon 14 waiting. The charging points 35 are for example via track cable 36 supplied, which are also shown in the previous pictures. In particular, the charging points 35 provided in each level.
