Description

The invention relates to a paternoster lift for pallets in a high-bay warehouse, wherein the high-bay warehouse has several floors, with a plurality of support means, which are adapted to receive the pallets, wherein the Paternoster lift for circumferential conveyance of the support means to the plurality of floors and formed with at least one turning area and with a pallet lock for loading and / or unloading pallets into the carrier devices. The invention also relates to a high-bay warehouse with at least one such Paternoster lift.

Paternoster lifts are special forms of elevator systems that transport individual cabins of the elevator system in a circulation principle. For this purpose, the paternoster lifts usually have a revolving drag connection, which is deflected at a lower and an upper inflection point. At the towing connection, the individual cabins are arranged at a distance from one another. The special feature of the paternoster lifts is that the individual cabins are constantly in circulation and that the paternoster lift can also be operated continuously. Comparing this form of lift with a conventional elevator with only one cabin, it can be seen that although the loading and unloading of individual cabins, especially in continuous operation, is much more difficult, the capacity due to the large number of individual cabins, however, significantly larger than that of conventional elevator is. Because of this advantage, the paternoster lift is also used as a goods lift and in particular for the supply of high-bay warehouses with general cargo.

The publication EP 0531669 B1 , which probably forms the closest stand, describes a storage arrangement for stored goods with at least one paternoster bearing, which has a plurality of bearing sets for stored goods, which are arranged as parts of a circumferentially movable paternoster and at a loading or unloading point of the paternoster camp reachable by circulation of the paternoster. or are loadable.

The invention has for its object to propose a Paternoster lift for pallets in a high-bay warehouse, which allows a further increase in the effectiveness of the high-bay warehouse. Furthermore, the invention has the object to design a corresponding high-bay warehouse.

These objects are achieved by a Paternoster lift with the features of claim 1 and by a high-bay warehouse with the features of claim 13. 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 paternoster lift is proposed, that is to say an elevator which is suitable and / or designed for transporting pallets in a vertical direction in particular in the circulation principle. Pallets are understood in particular to be palletized general cargo, general cargo with pallet sections, lattice box pallets and / or general cargo on pallets, in particular so-called Euro pallets. Preferably, the pallets have a weight of more than 100 kg, in particular more than 300 kg, in particular more than 1000 kg.

The paternoster lift is suitable and / or designed for interaction with a high-bay warehouse, wherein the high-rack warehouse has several floors in the vertical direction. In particular, the high-bay warehouse is designed for storage of the pallets. The paternoster lift conveys the pallets to the different floors where the pallets are stored or retrieved.

In addition, the paternoster lift comprises a plurality of support means, which can be loaded with the pallets. The carrier devices can be designed, for example, as cabins, carrier racks or other mechanical interfaces for the pallets.

The paternoster lift is designed for the circulating conveyance of the support devices, possibly with recorded pallets, to the several floors. The paternoster lift comprises at least one turning region in which the direction of movement of the carrier devices is changed, in particular reversed. In one possible embodiment, the paternoster lift comprises two vertical conveying sections and in each case a turning section, which in particular form an upper and a lower dead center for the circulating conveyance of the carrier devices.

Particularly preferably, the paternoster lift comprises a circulating drag connection for the purpose of conveying the carrier devices, which may be designed, for example, as one or two circulating carrier chains or carrier belts.

For a loading and / or unloading of pallets in the carrier devices, the paternoster lift comprises a pallet lock.

In the context of the invention it is proposed that the pallet lock is arranged in the turning area of the paternoster lift and the paternoster lift is formed, the carrier devices through the pallet lock with a continuous speed, in particular a uniform and / or constant speed in a direction of movement to perform. The pallet lock is structurally designed so that the pallets are inserted or removed in or against the direction of movement of the support means. In particular, the locks, so the input and / or removal, automated.

It is a consideration of the invention that a continuously conveying paternoster lift would have a very high conveying capacity. However, paternoster lifts for goods often have to be operated intermittently or intermittently, with the paternoster lift being stopped for loading and / or unloading in the floors or infeed and / or outfeed in the pallet lock. This interruption of the movement requires increased energy consumption and also reduces the delivery rate. In contrast, the invention proposes to remove or load the pallets in a turning region of the paternoster elevator from the active movement of the carrier devices in or against the direction of movement. As a result, the conveying speed of the paternoster elevator does not have to be reduced or even stopped, at least for the entry and / or exit, so that a significantly higher delivery rate results.

In a preferred embodiment, the pallet lock is arranged at the lower turning area of the paternoster lift. This is recommended because high-bay warehouses are usually loaded from the base area. Particularly preferably, the turning area extends over a horizontal area, wherein the carrier devices are moved in the direction of movement parallel to the ground or to the base area.

With the aim that sufficient time is created for the sluice of the pallets, it is preferred that the run length of the horizontal area and / or the run length of the pallet lock extend over at least 3, preferably over at least 4 pallet lengths.

In one possible embodiment, for example, the pallets are deflected coming out of the vertical direction during discharge and conveyed horizontally in the pallet lock, the horizontal run length extending over the at least 3 or 4 pallet lengths.

In a preferred embodiment of the invention, the pallet lock is designed to load the pallets in the direction of movement in the carrier device and / or unload from the carrier device. To achieve this, a pallet to be inserted or a pallet to be rejected must have a higher, absolute pallet speed than the conveying speed of the carrier device in the direction of movement.

In an alternative embodiment of the invention, the locks are respectively in the opposite direction, so that the pallets to be inserted and the auszuschleusenden pallets are inserted or extended against the direction of movement of the carrier device in the carrier device.

Figuratively speaking, for the first embodiment, the pallets to be rejected are brought to a speed such that they overtake the carrier device in the direction of movement and in the second embodiment reduce the speed of the pallet to be rejected relative to the carrier device, so that the pallet to be rejected is unloaded against the direction of movement becomes. In particular, the second embodiment has the advantage that the absolute pallet speed of the pallets is at most as large as the conveying speed of the carrier devices in the direction of movement. On the other hand, the first embodiment has the advantage that the risk of collision of the pallets to be rejected with subsequent carrier devices is reduced.

In a possible structural realization of the invention, the pallet lock on a conveyor, which is designed to convey the support means and the pallets to be inserted and / or the auszuschleusenden pallets along the direction of movement. In particular, the conveyor is designed to convey the carrier devices and the pallets at different speeds in order to enable the locks in the manner described.

In a possible concretization of the invention, the conveyor has a main circuit conveyor, which is designed for conveying or at least guiding the carrier device. The conveying speed of the main circuit conveyor corresponds to the speed of the carrier device in the direction of movement of the paternoster lift. A circular conveyor is understood in particular to mean a conveyor system which uses a circulating conveyor belt or a circulating conveyor chain. It can be provided that the carrier device is placed on the main circuit conveyor and is moved by this in the direction of movement. Alternatively, the carrier device is moved in the direction of movement by the drag connection of the paternoster lift and only guided or stabilized by the main circuit conveyor. It is also possible for the main circuit conveyor and towing connection to interact, so that the carrier device is moved by the main circuit conveyor and the towing connection.

In a preferred embodiment of the invention, at least one loading circle conveyor is arranged on the main circuit conveyor, which is designed to convey the pallets. The loading circle conveyor is thus moved with the main circle conveyor, but allows to set a different speed for the pallets than for the carrier device.

In a specific embodiment of the invention, the main circuit conveyor has a main chain with at least one transport space for the carrier device and a loading chain for transporting the pallet, wherein the loading chain is transported through the main chain in the direction of rotation of the main chain. The transport space may be formed as a gap in the direction of rotation of the main circuit conveyor between two end portions of the loading circle conveyor. When using more than one loading circle conveyor, preferably two loading circle conveyors, in the conveying device, the transport places, in particular the gaps, and the loading circle conveyors are arranged alternately in the direction of rotation of the main circle conveyor.

It is particularly preferred that the main circuit conveyor and the at least one loading circle conveyor each have their own drive assigned. While the drive of the main circuit conveyor is preferably arranged stationary, it can be provided that the drive for the at least one loading circle conveyor is also moved on the carrier chain of the main circuit conveyor. The power supply of the drives for the at least one loading circle conveyor can be done via a sliding connection or a sliding contact. However, particularly preferably, the drive of the charging circuit conveyor is assigned a supercap (capacitor) or another energy storage device, which is also moved in the direction of rotation with the main circuit conveyor and which are charged or recharged contactless, in particular inductively.

Furthermore, it is particularly preferred if the carrier device has an autonomous transport device, in particular a chain conveyor, for loading and unloading the pallet, in particular in or against the direction of movement. Due to the autonomous Transportverrichtung the carrier device when it is set to the transport location of the main circuit conveyor, the pallet loading or unloading and handed over to the loading circle conveyor. The energy supply of the transport device can take place via a supercap (capacitor) or another energy storage device, which is moved along with the carrier device, so that it is also available in the other floors. The supercap or the energy storage device can be charged in preferred embodiments contactless, in particular inductive or sliding contacts in the range of the pallet lock. In particular, it is provided that the charging takes place when the carrier device is on the transport location.

For example, the transport device is designed as a conveyor belt, roller conveyor or chain conveyor, which conveys the pallet in or out of the carrier device. Particularly preferably, the transport device has a self-sufficient power supply, in particular a battery or a supercap (capacitor), so that the cabling effort can be kept low.

Another object of the invention relates to a high-bay warehouse for pallets, wherein the high-bay warehouse has several floors. According to the invention, the high-bay warehouse comprises the paternoster lift according to one of the preceding claims or as has just been described, wherein the paternoster lift for the supply and disposal of the different floors of the high-bay warehouse is arranged and / or formed with pallets. In particular, the paternoster lift is designed to bring the pallets from the pallet lock to a predetermined floor or from a predetermined floor to the pallet lock or from one floor to another floor.

In a preferred embodiment of the invention, the high-bay warehouse comprises a plurality of high racks which are arranged in rows so that aisles result between the rows. In the high shelves bearing channels are formed in which at least one pallet can be stored, wherein in one of the high shelves at least two bearing channels are arranged in different planes one above the other. Usually, at least five levels, preferably at least ten levels and in particular at least 15 levels are provided in a high bay, which have storage channels with at least two storage spaces for pallets, preferably at least five storage spaces and in particular at least ten storage spaces. In a high bay preferably at least five bearing channels, preferably at least ten bearing channels and in particular at least 15 bearing channels are arranged in the horizontal direction next to each other. The high-bay warehouse has a rail system comprising a channel rail area in the storage channels and a gangway area in the aisles and has at least one so-called tandem shuttle, which comprises a gang carriage and a channel cart, wherein the gang carriage for driving on the gangway area and the channel carriage for a Driving on the channel rail area is formed. The channel cart is optional for transporting a pallet in the channel rail area and the gang carriage for transporting the channel car with the pallet in the Gangway area formed. The channel trolley transports the gang car piggyback. In particular, a tandem shuttle is arranged in each level of the high rack. In the high-bay warehouse it is provided that the paternoster lift for distributing the pallets on the different floors and the tandem shuttle for distribution of the pallets is formed within a floor. Preferably, at least one high rack, some of the high shelves or all of the high shelves of the high-bay warehouse on such a paternoster lift on.

Particularly preferably, the paternoster lift is integrated or arranged in the high-level rack, so that the direction of movement in the pallet lock runs parallel to the storage channels of the high rack.

In a particularly preferred embodiment, loading channels are provided in the floors of the high rack, which serve for dispensing or receiving the pallets from the carrier devices. The charging channels are similar to the storage channels formed. In particular, the charging channels are aligned parallel to the bearing channels. It should be emphasized that in this constructive embodiment, the loading channels are arranged congruent to the pallet lock viewed from above in plan view. In particular, the charging channels and / or the bearing channels are formed multiple deep, d. H. In channel direction at least two, three, four or more pallets can be arranged

In a possible embodiment of the invention, the Paternoster lift is designed to supply two high shelves, the Paternoster lift is arranged on the front side of the two high shelves and wherein between the two high shelves a gangway area is arranged. The log shelves, which are logistically interconnected by a common gear rail area, are also referred to as double blocks or high-shelf pairs and form a common storage area. The paternoster lift is preferably designed such that the run length of the pallet lock or the pallet lock itself is arranged parallel to the bearing channels. The loading channels in the different floors are also aligned parallel to the storage channels and open to each other so that the loading channels can be supplied with pallets via the gangway area. Overall, the high-bay warehouse is designed so that pallets can be brought with the tandem shuttle on the gangway area to the loading channels and can be retracted via a channel rail area with the channel cars in the loading channels to be transported from there via the Paternoster lift.

In one possible development of the invention, the high-bay warehouse has a Zuatzlift, which is designed to transport the Tandemshuttles between the floors. In particular, the additional lift is arranged in a head region of the gear rail area. In particular, in this embodiment may be assigned to a tandem shuttle more than one floor, in particular, the number of Tandemshuttles may be smaller than the number of levels.

Through the use of the paternoster lift with at least one tandem shuttle, preferably at least one tandem shuttle per high bay, in particular at least or exactly one tandem shuttle per level to be supplied in the high bay, the entire high bay warehouse can be optimized in terms of conveying speed. Since the paternoster lift already ensures a higher throughput of pallets, a suitable number of tandem shuttles can be used to adjust the distribution rate of the pallets in one floor so that the paternoster lift can always be utilized. Thus, the two components paternoster lift and Tandemshuttle form the building blocks for a high-speed bearing that enables high throughput.

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

1 a schematic plan view of a high-bay warehouse with paternoster lift as a first embodiment of the invention with two different alternatives;

2 a schematic frontal view of the high-bay warehouse in the 1 ;

3a to f in a schematic lateral plan view, the removal and introduction of pallets in the Paternoster lift in a pallet lock at the lower turning point in a cartoon-like representation;

4 a schematic three-dimensional representation of the conveyor in the pallet lock.

The 1 shows a schematic plan view of a high-bay warehouse 1 , which has several high shelves 2a , b, c, d includes, in multiple, vertical planes storage channels 3 each have five storage bins 4 for pallets 5 exhibit. In the illustrated schematic plan view are the storage bins 4 partly with pallets 5 occupied, which is indicated graphically by a hatched box. One such high-bay warehouse 1 is z. B. used in transport logistics to temporarily store pallets. The pallets are in particular so-called europallets.

The high rack pairs 2a , Federation 2c , d form each as a double block a common loading area and are each with one of the paternoster lifts 6 operated, leaving one of the paternoster lifts 6 two high shelves each 2a , b or 2c , d is assigned. The paternoster lifts are used to distribute pallets 5 on the different levels of the assigned high-bay warehouse 2a , b or 2c , d. For the supply and disposal of pallets 5 has the high-bay warehouse 1 a conveyor technology 7 , for example, a conveyor belt, which, on the one hand the paternoster lift 6 according to arrow 8a with pallets 5 supplied or according to arrow 8b pallets 5 from the paternosters 6 disposed of. The conveyor technology 7 is with the Hochregalpaaren 2a , Federation 2c , d formed differently, as will be explained later.

The 2 shows a schematic frontal plan view of the high shelves 2a , b, being different floors 9 the high shelves 2a , b are recognizable. The paternoster lift 6 has a variety of carrier devices 10 on top of each other via two towed connections 11 or chains are connected. The towing connection 11 is formed circumferentially and / or endless, so that the carrier devices 10 are transported upwards in an upward direction U, are moved horizontally in the upper turning area OW, are moved downwards in a downward direction D and return to their initial situation in the lower turning area UW again in a horizontal movement. The carrier devices 10 are insoluble or permanent with the towing connection 11 connected.

The transfer or delivery of pallets 5 for feeding into and out of the paternoster lift 6 takes place in a pallet lock 12 through the materials handling 7 supplied with pallets. The pallet lock 12 is arranged in the illustrated view between an elevator shaft section for the upward direction U and a winding shaft section for the downward direction D in the lower turning area UW.

In operation, for example, new pallets 5 in the pallet lock 12 introduced and subsequently transported in the upward direction U upwards. In the desired floor 9 become the pallets 5 then from the paternoster lift 6 in the high rack 2 B , d at input buffer locations E in a charging channel 17 stored. In a similar way, pallets 5 of paging buffer locations A of loading channels 17 to the moving in the downward direction D support means 10 pass and in this way from the high bay 2a outsourced, b, c, d.

Between the high shelves 2a and 2 B respectively. 2c and 2d are in every floor 9 transition rails 13 ( 1 ) provided by a tandem shuttle 14 are drivable and form a gangway area. The tandem shuttle 14 has a gear cart 15 on, which over the gear rails 13 drives as well as one on the gang carriage 15 mounted sewer car 16 , which of the gaiter 14 piggyback is transported and is trained in the storage channels 3 and optionally in the charging channels 17 to drive in to pallets 5 to pick up or shut down. These are in the storage channels 3 or charging channels 17 , especially in all storage channels 3 or charging channels 17 , Bearing rails 18 introduced, which form a channel rail area.

The from the paternoster lift 6 transported pallets 5 , which are provided for storage at the storage buffers E, are from the tandem shuttle 14 picked up, over the gear rails 13 transported until the desired warehouse channel 3 is reached and then from the sewer truck 16 to the desired storage location 4 posed.

Outsourcing is done in reverse order, with the tandem shuttle 14 to the warehouse channel 3 the pallet to be picked up 5 drives, there the channel car 16 in the warehouse channel 3 retracts, the desired pallet 5 charges and then with the charged range 5 on the gang carriage 14 parked. The gang car 14 subsequently moves to the charging channel 17 the paging buffer A, where the channel trolley 15 then the pallet 5 on a paging space A provides. From there, the palette becomes 5 the paternoster lift 6 pass from this to the pallet lock 12 brought and about the conveyor technology 7 disposed of. If the pallet to be picked up in its warehouse channel 3 not at the front but behind other pallets 5 , stores the tandem shuttle 14 first the pallets in front of it 5 on free bins 4 in adjacent storage channels 3 or in storage channels 3 the same level around.

The paternoster lift 6 is at the front of the high rack pairs 2a , b (resp. 2c , d, 1 ), wherein the elevator sections U for upward direction and for the downward direction D, the loading channels 17 clasp or embrace, so that the lift sections for the upward and downward direction U, D in the same vertical plane as the loading channels 17 are arranged. Here are the elevator sections for the upward and downward direction U, D instead of the outer storage bins 4 in the charging channels 17 provided so that the charging channels 17 instead of the usual five bins 4 in this example, have only two input buffer locations E or only two output buffer locations A. This structure has the advantage that the paternoster lift 6 in frontal plan view as in the 2 shown not protruding laterally so that adjacent High-speed pairing (eg 2c , d, 1 ) Another paternoster lift 6 can be installed without the distance between the Hochregalpaaren 2a , Federation 2c to have to enlarge d. The charging channels 17 are parallel to the storage channels 3 arranged and used by the paternoster lift 6 in the vertical plane starting from the elevator sections for the upward direction U and for the downward direction D in the direction of the gear rails 13 with the pallets 5 provided. The movement of the pallets 5 in the floors 9 thus takes place in the direction or opposite direction to the longitudinal extension of the loading channels 17 ,

The upper turning area OW is above the highest floor 9 arranged so that these with pallets 5 can be supplied. The lower turning area UW, on the other hand, passes through the pallet lock 12 educated.

It is particularly advantageous that in the paternoster lift 6 the towing connection 11 in the upward direction U and downstream direction D is operated at a constant or continuous conveying speed, since this optimum performance and minimum energy consumption is achieved. Also during piling and storage operations, the towing connection 11 not delayed or stopped. In order now to safely unload or store the pallets 5 to enable, by a provisioning device, the up-moving range 5 or the descending pallet 5 despite continuously moving towing connection 11 briefly stopped for the storage and removal process, as explained below and in the 2 is indicated by drawing:
In a first step, the carrier device 10 with the same conveying speed as the towing connection 11 moved in the upward direction U. In the desired level 9 becomes the carrier device 10 stopped by a braking device, which z. B. is designed as a brake shoes, the carrier device 10 fixed. In this case, the carrier device 10 slowed down by gravity. After the tow connection 11 is moved further with continuous conveying speed, the relative position between the carrier device must inevitably 10 and the tow connection 11 to change. This is done by a misalignment device 19 , which is designed as a telescopic device, achieved as a connection between the towing connection 11 and the carrier device 10 is trained. The offset device 19 is designed to change in the conveying direction F, the length, so that a relative distance between a connection point of the displacing device 19 at the tow connection 11 and the carrier device 10 can be changed. By extending the offset device 24 in the conveying direction F, it is possible for the carrier device 10 to temporarily stop for the storage process.

In this stopped or stationary state, the pallet is now 5 retracted into the pallet buffer space E. After the pallet 5 is retracted into the pallet buffer space E, the braking device 23 released again and the empty carrier device 10 is accelerated again in the conveying direction F without load and thus with low energy consumption. In the 2 is also shown as the support means in the area U with extended offset device 19 after unloading the pallet 5 continues to drive.

The outsourcing of pallets 5 , where pallets 5 from the high rack 2a , b, c, d to the paternoster lift 6 be passed, takes place during the downward movement of the carrier devices 10 in the direction of D instead. The carrier device 10 moves with extended offset device 19 in the downward direction D and will be on the desired floor 9 again fixed by a braking device. In order to change the relative position between the fixed carrier device 10 and the trailing link moving at the conveying speed 11 To compensate, is the offset device in the outsourcing 19 reduced in length. During this time, the palette becomes 5 from the pallet buffer space A to the carrier device 10 hazards. After the pallet 5 completely on the carrier device 10 is positioned, the carrier device 10 by releasing the brake device 23 released again and together with the carrier device 10 in the downward direction D, wherein the acceleration of the loaded carrier device 10 supported in the downward direction by gravity.

The change in the length of the offset device 19 is in the 2 represented, wherein in the upward direction U, the empty carrier means 10 an extended misalignment device 24 and backward filled carrier means 10 retracted displacement devices 24 exhibit.

In order to be able to maintain the constant conveying speed also when entering and / or discharging - hereinafter referred to as "locks" - allows the pallet lock 12 the sluice of the pallets 5 during a movement of the carrier devices 10 with a continuous speed.

The 3a shows a schematic representation of the paternoster lift 6 in the area of the pallet lock 12 , The pallet lock 12 includes a conveyor 20 which promote the support facilities 10 in a direction of movement B along the course of the towing connection 11 is formed in a horizontal plane. In particular, the conveyor transports 20 the carrier devices 10 parallel and / or concurrent with the towing connection 11 in the direction of movement B at a continuous speed.

In addition, the pallet lock includes 12 a first roller lifting table 21a and a second roller lifting table 21b , which are used to take over or hand over the pallets 5 from the conveyor technology 7 and for the transfer or delivery of the pallet 5 on the conveyor 20 are formed and / or arranged.

The conveyor 20 is designed as a double conveyor in the circular circulation principle, wherein a main circuit conveyor 22 and a loading circle conveyor 23 are provided. On the main circle conveyor 22 becomes the carrier device 10 immediately attached. The loading circle conveyor 23 is, however, by the main circuit conveyor 22 transported circumferentially, with an input or auszulagernde pallet 5 directly on the loading circle conveyor 23 is put on, the pallet 5 on the loading circle conveyor 23 can be transported at a different absolute speed than the carrier device 10 on the main circuit conveyor 22 , The operation of the pallet lock 12 will be sent to the following 3a - 3e explains the structural design of the conveyor 20 arises from the 4 ,

In the 3a is the pallet lock 12 represented at a process time of, for example, 0 seconds, with a pallet 5 (A) on the roller lifting table 20b during cross transport to conveyor technology 7 is shown. A palette 5 (D) is in a carrier device 10 (PT1) just before lifting off the conveyor 20 shown. On the other hand is a palette 5 (B) in a carrier device 10 (PT2) shown just before putting on the conveyor 20 is.

In the 3b is the pallet lock 12 shown at a process time of, for example, 1.5 seconds, with the pallet 5 (A) has already been rejected and for this reason is no longer shown. The pallet 5 (D) is with the carrier device 10 (PT1) during transport in upward direction U for storing the pallet 5 (D) in the high-bay warehouse 1 ,

The carrier device 10 (PT2) with the palette 5 (B) is on the conveyor 20 on a parking space of the main circuit conveyor 22 mounted, which is in the direction of movement B at the same speed as the towing connection 11 moves, so the carrier device 10 (PT2) parallel to the towing connection 11 to be led. The pallet 5 (E) sits on the roller lifting table 20a and is provided for entry.

In the 3c is the pallet lock 12 at a process time of exemplarily 3 seconds shown. The pallet 5 (D) in the carrier device 10 (PT1) is further transported in the U direction. The pallet 5 (B) will be on the conveyor 20 from the carrier device 10 (PT2) on the loading circle conveyor 23 the conveyor 20 hazards. For this process is in each carrier device 10 a chain conveyor 24 arranged, which is supplied with power autonomously, and which is a handover of the pallet 5 (B) in the direction of movement B allows. The pallet to be rejected 5 (B) is on the loading circle conveyor 23 set which the pallet 5 (B) in the direction of movement B and with an absolute speed greater than the transport speed of the carrier device 10 (PT2). Thus, the auszuschleusende pallet 5 (B) in the direction B of the carrier device 10 moved away. For example, the palette 5 (B) at twice the absolute speed as the carrier 10 be moved in the direction of movement B. The pallet 5 (E) is from the roller lifting table 21a on the same or another loading circle conveyor 23 been set, the pallet 5 (E) is moved at a speed which is greater than the speed of the carrier device 10 (PT2) is in direction B, so the palette 5 (E) in the carrier device 10 (PT2) can be retracted.

The 3d shows the process lock 12 at a process time of, for example, 4.5 seconds. At this time, the palette is 5 (B) from the carrier device 10 (PT2) completely discharged and becomes straight to the Rollenhubtisch 20b transported. The pallet 5 On the other hand, (E) is on the carrier device 10 (PT2) and for transport to the upper floors 9 of the high-bay warehouse 1 ready.

The 3e shows the process lock 12 at a process time of exemplarily 6.0 seconds. The pallet 5 (B) is meanwhile on the Rollenhubtisch 21b arrived and ready for transport via the conveyor system 7 , The carrier device 10 (PT2) with the palette 5 (E) is ready for promotion to the upper floors 9 , In the area of the elevator shaft for the downward movement D is another support means 10 (PT3) with a palette 5 (C) retracted and is about to be placed on the conveyor 20 ,

The 4 shows in a schematic three-dimensional representation of the conveyor 20 from the pallet lock 12 , The conveyor 20 is designed as a double conveyor in the circulation principle. The length of the conveyor 20 in direction of movement B corresponds to more than five or six pallet widths. On the one hand, this run length is necessary to ensure sufficient process time for the infeed and outfeed of the pallets 5 On the other hand, the run length makes sense, as in the other floors 9 the charging channels 17 congruently or in flight to the pallet lock 12 are arranged.

The conveyor 20 has a main chain 25 at a rotational speed equal to the revolution speed of the towed connection 11 the paternoster lift 6 is. The main chain 25 is about a main drive 26 driven and allowed in one or more transport sections 27 the placement of the carrier devices 10 so this on the main chain 25 or at the main chain 25 mounted guide devices rest and is transported by this in the direction of movement B. This forms the main chain 25 the main circle conveyor 22 ,

On the main chain 25 are between the transport sections 27 two side chains 28 arranged, which the loading circle conveyors 23 form. The side chain 28 is on the main chain 25 arranged such that the side chain 28 in the direction of rotation with the main chain 25 is moved. A PTO 29 for driving the side chain 28 is also from the main chain 25 carried in the direction of rotation and allows an independent drive of the secondary chain 29 and thus the loading circle conveyor 23 , The side chain 28 or the loading circle conveyor 23 allow thus over the auxiliary drive 29 to superimpose an additional speed in or against the direction of movement B. The side chain 28 is on the main chain 25 arranged so that the top of the side chain 28 at the same height as the chain conveyor 24 the carrier device 10 is, so the carrier device 10 the pallet 5 on the side chain 28 or the loading circle conveyor 23 can pass and this the pallet 5 then can carry away in the described way. Analogously, via the side chain 28 or the loading circle conveyor 23 a pallet 5 on the carrier device 10 be driven.

The power supply of the auxiliary drive or drives 29 for the loading circle conveyor 23 is contactless, in particular inductive, so that it is possible to dispense with wear-prone slip connections. Likewise, self-sufficient energy storage devices, eg. As supercaps, in the carrier devices 10 in the pallet lock 12 be charged so that the chain conveyor 24 the carrier device 10 both in the pallet lock 12 as well as in the other floors is energy self-sufficient operable.

The conveyor technology 7 can - as in the 1 on the left side - shown formed as two mutually parallel conveyor belts, which are the Rollenhubtische 20a , b with pallets 5 serve. Alternatively, the conveyor technology 7 about steering shuttles 30 be served, which z. B. similar to the Tandemshuttles 14 can be trained and transport the pallets in the warehouse Vorzone.
