Description

Field of the invention

The invention relates to a method for operating a hanging bag warehouse with stored goods held in hanging bags and to a hanging bag warehouse according to the method.

State of the art

In automated warehouses, production facilities and when transporting goods, such as in mail order, it is necessary to load goods into and unload them from containers as automatically as possible. The goods can be stored in these containers before they are delivered and then reach the station where they are packaged for further transport to the customer. Transport within the warehouse is usually carried out using overhead conveyors. The containers are usually bags that are made like fabric bags and are hung on a rail system with a kind of wire hanger at the top. Such a container is available from the WO 2014/012965 A1 known. Its side wall elements are controlled via a rod so that the side wall elements, which are connected to one another via a connecting area, can be opened up. In the area of a loading station, the containers are also transferred to a horizontal or inclined position.

Comparable containers for conveying goods and associated overhead conveyor systems are known, for example, from EN 10 2004 018 569 A1 , EP 2 130 968 A1 or EP 2 196 415 A The transport bags described there are made of flexible materials in the form of a loop in which the goods to be conveyed are held. For loading, these transport bags are opened from above in order to be able to place the goods to be conveyed into the loop. Unloading is carried out by either removing the goods from the side of the loop or ejecting them or, for example, according to the EP 2 130 968 A1 the loop is opened downwards. Furthermore, the DE 103 54 419 A1 A conveyor carrier is known which has a relatively rigid and flat plastic wall with a cutout for loading and unloading with conveyor material. Other conveyor containers are made like hanging flat plastic tubs which are covered on one side with elastic materials, which clamps the conveyor material.

It is known to load such containers mechanically and unload them manually. A transport cycle is based on the slowest process, which also depends on the amount of transported goods. In particular, a large number of individual goods can slow down loading and/or unloading. For example, unloading and/or assembling disassembled transport containers can determine the maximum possible transport cycle. The EP 2 686 258 B1 relates to a suspended conveyor system with a transport bag for automatically unloading a loaded piece of goods and with an unloading station. The transport bag has a horizontal base on which the piece of goods can be stored for transport purposes. The base interacts with a lifting device which is designed to raise the base of the transport bag loaded with at least one piece of goods in a vertical direction when the transport bag is in an unloading position in such a way that the at least one piece of goods can be pushed out centrally by means of a pushing device through a front side of a base body of the transport bag, wherein the pushing device has a slide which engages through another front side of the base body into an interior of the base body where the at least one piece of goods is located when the base is raised. For unloading, the two opposite open front sides, the base which can be raised in the vertical direction and the slide of the pushing device which reaches through one of the front sides are therefore required. From the EN 20 2017 100 206 U1 A conveying material container for a suspended conveyor system for transporting conveying material is known, which can be adjusted between an open position and a closed position. The conveying material container has a base that is mechanically associated with an ejection device. By means of the ejection device, the base can be adjusted between a transport position in which the conveying material can be stored within the conveying material container, and an ejection position in which the conveying material can be ejected from the conveying material container.

From the EN 10 2018 105 795 A1 A method for loading or unloading a conveyed material held on a flexible material of a conveyed material container by means of a station such as an unloading station and/or a loading station of an overhead conveyor system, as well as a conveyed material container, unloading station and overhead conveyor system according to the method, are known. The conveyed material container is brought closer to the station, where an attractive force is then created between the station and the conveyed material container to couple the flexible material of the conveyed material container. The conveyed material container coupled in this way is tilted and the conveyed material is ejected from the conveyed material container in a sliding movement.

The EN 10 2018 128 417 A1 describes a method for transporting and sorting a sorting bag suspended from a rolling adapter rolling on a rail network of a sorting system for transporting a piece of goods, characterized characterized by: providing the rail network of the sorting system, providing the rolling adapter of the sorter bag that rolls on the rail network, providing electrical drive energy for the rolling adapter, converting the electrical drive energy provided by means of the rolling adapter itself into kinetic energy for transporting the sorter bag, and devices according to the method. The rolling adapters are used to hang and move the sorter bags. For this purpose, they each have a chassis with two coaxially rotating wheels, a suspension arranged between the wheels and carried by them, on which the sorter bag is suspended, an electric drive for driving the wheels and a control device or partial control device for autonomously or at least partially autonomously controlling the rolling adapter along a route selected from a multitude of routes.

It is also known that industrial objects communicate with each other according to a network standard, which is also referred to as the Industrial Internet of Things (IIoT).

Summary of the invention

Based on this prior art, the present invention is based on the object of enabling retrieval processes and/or sorting processes, in particular up to 30,000 per hour, at a particularly high storage density in a hanging bag warehouse with a large number of autonomously or at least partially autonomously movable hanging bags, in particular with over a million individual hanging bags.

The task is solved in a method for controlling a hanging bag warehouse with goods stored in hanging bags by storing the goods stored in the hanging bags in a row on a storage line of the hanging bag warehouse, scheduling one of the goods in the row for retrieval, clearing a retrieval path for the planned goods by moving further goods in the row to a shunting line and/or a highway of the hanging bag warehouse by means of circling or oscillating the further goods in the row over the storage line and another storage line arranged parallel and adjacent to it in a direction of rotation, and retrieving the planned goods along the cleared retrieval path on both sides of the storage lines. Because the retrieval takes place on both sides, faster retrieval can take place, whereby an optimized path can be selected depending on the destination.

Preferably, the other stored goods can rotate in a first direction of rotation in a block of the hanging bag storage, with the storage lines being arranged adjacent to one another. By rotating, all of the stored hanging bags can be gradually brought to an edge of the storage lines in a cyclical manner and retrieved when required.

In a preferred embodiment, the other stored goods are rotated in a plurality of adjacent storage lines in the direction of rotation. All hanging bags can be moved in the same direction of rotation, which causes movements in the same direction at the ends of the storage lines. This can speed up the removal from storage.

Alternatively or additionally, the other stored goods are rotated in an opposite direction and in a plurality of adjacent storage lines in another block arranged adjacent to the block. This allows movement in the same direction to be achieved between the blocks, whereby removal of the hanging bags between the blocks is simplified.

Preferably, there is exactly one shunting lane and one expressway between the block and the next block. This means that when several blocks are arranged, one-sided removal can be carried out via the shunting lane and particularly rapid removal via the expressway. Storage space can be saved.

Another advantageous option is to arrange just one expressway between the block and the next block. In this case, the expressway is also used as a shunting lane, which also saves storage space. The circling can continue until the goods to be removed have reached one of the two edges of the corresponding storage lane, and then stop again immediately. This means that the single route between the blocks, which can be used jointly as a shunting lane and a storage lane, or at least reduced to two roads, is free again and can be used to transport the planned goods or hanging bags, i.e. as an expressway. In this way, the resources of routes required for movements between the storage areas and the unloading station can be reduced to a minimum.

Furthermore, the process can be carried out by driving the machine in a direction-specific manner and adapted to the direction of rotation and the further direction of rotation. This will allow a consistent and optimized flow of traffic on the expressway.

A further preferred embodiment of the method is carried out with direction-bound driving on the expressway and the shunting lane, adapted to the direction of rotation and the further direction of rotation. This makes it possible to achieve a uniform and thus optimized flow of traffic on the expressway and the shunting lane.

The task is also solved by a hanging pocket storage system for carrying out a previously described method. This results in the advantages described above.

Finally, the task is solved in a hanging bag warehouse for storing and sorting goods that can be accommodated in hanging bags by a large number of levels, each with: a network on which the hanging bags can be moved autonomously or at least partially autonomously, a large number of storage lanes of the network arranged parallel to one another for storing the goods accommodated in the hanging bags, a block and at least one further block arranged adjacent to it in which the storage lanes are arranged, at least one shunting lane into which the large number of storage lanes flow and/or at least one expressway that is connected downstream of the large number of storage lanes and/or the at least one shunting lane, with exactly one of the expressways or exactly one expressway and exactly one of the storage lanes being arranged between the blocks. Traffic for retrievals can take place in the same direction between the blocks. This can speed up retrieval processes. Only two or only one lane is arranged between the blocks, so that a comparatively large amount of storage space is available.

Further advantages emerge from the subclaims and the following description of a preferred embodiment.

Description of preferred embodiments

Before the invention is described in detail, it should be noted that it is not limited to the particular components of the device and the particular method steps, since these components and methods may vary. The terms used herein are intended only to describe particular embodiments and are not used in a limiting sense. In addition, when the singular or indefinite articles are used in the description or in the claims, this also refers to the plural of these elements, unless the overall context clearly indicates otherwise.

1 shows a schematic three-dimensional view from the side at the front and top of a hanging pocket storage unit 1.

The hanging pocket storage 1 has at least two levels 9, 13, here a total of four, with a first level 9 and a second level 13 being provided with reference symbols by way of example. More or fewer levels are conceivable, for example 10 levels or more, which are arranged vertically one above the other.

Each of the levels 9, 13 of the hanging pocket storage 1 has a transfer buffer 7, 11, of which only a first transfer buffer 7 and a second transfer buffer 11 are provided with reference symbols.

The hanging bag storage 1 is used for receiving, storing, sorting and/or retrieving stored goods 3. Optionally as a pure storage or sorting device. The transfer buffers 7, 11 are preferably arranged vertically one above the other, which is symbolized by a line 27. However, it is also conceivable to arrange at least two of the transfer buffers 7, 11 one above the other and/or to arrange them at an angle to a vertical spatial direction along the line 27.

A ring conveyor system 23, preferably a plurality of such, also runs along the imaginary line 27 along which the transfer buffers 7, 11 are arranged. The transfer buffers 7, 11 are arranged adjacent to the ring conveyor system 23 in such a way that the stored goods 3 are transferred from them into the ring conveyor system 23 and/or can be stored from there in levels 9,13 or the transfer buffers 7, 11 of levels 9, 13.

In one embodiment, the stored goods 3 are transferred directly to the ring conveyor system 23. Preferably, the stored goods 3 are transferred to the ring conveyor system 23 in a hanging pocket 5. Particularly preferably, the entire hanging pocket 5 is driven, controlled and/or moved autonomously before it is made available, when the hanging pocket 5 is made available and/or transferred. The process is carried out in particular without drag chains. For this purpose, the hanging pocket warehouse 1 is, for example, constructed without drag chains at least in some areas or entirely, preferably at least within the levels 9, 13.

For this purpose, the hanging pocket storage 1 has a network 49, for example a rail network with connecting sections and branches such as crossings and/or switches. Preferably, this is a grid with straight rails connected to one another by the crossings and/or switches. For example, with rectangular meshes.

In order to store the storage goods 3 in the hanging bag warehouse, this has a transfer point 53, via which the individual storage goods are transferred into individual hanging bags 5. Preferably, only one of the storage goods 3 is transferred per hanging bag 5. However, several are also conceivable, provided that they can be accommodated in the corresponding hanging bag 5. In the transfer point, the storage goods 3 can optionally be buffered and transferred directly into the hanging bags 5, which head for the transfer point 53 and then drive autonomously to a storage location in the hanging bag warehouse 1.

At an unloading station 55 of the hanging bag warehouse 1, the stored goods 3 are removed from the ring conveyor system 23 and are preferably available there in a predetermined or predeterminable order 15. It is conceivable that a column of hanging bags 5 in the desired order 15 from the ring conveyor system 23 enters the unloading station 55 or is transferred from the ring conveyor system 23 to it, unloaded there and then returned for further loading. The unloading station 55 can be arranged inside or outside one of the levels 9, 13, preferably in a lowest level. Alternatively, however, it is also conceivable that the hanging bags 5 are conveyed by means of the ring conveyor system 23 and unloaded at the unloading station 55 in the desired order and immediately transported back empty to the hanging bag warehouse 1, i.e. without the respective hanging bags 5 being directly available there, for example to be transported further to the transfer point 53 after unloading.

Particularly preferably, the hanging pockets 5 are designed so that they travel autonomously along the network 49. Hanging pocket warehouses 1 with autonomously moving hanging pockets 5 are known and, for example, in the DE10 2018 128 417 A1 described, so that a more detailed description is omitted here. Preferably, a control device 25 is provided for monitoring and controlling the hanging pocket storage 1, in particular for specifying the desired sequence 15 and controlling the ring conveyor system 23, which exchanges information with the functional units of the hanging pocket storage 1.

2 shows a schematic side view of such a hanging pocket 5 for the 1 shown hanging pocket bearings 1 and 3 a schematic side view of several of the 2 shown hanging bags 5, suspended in the network 49, which is designed as a rail network, for example. For this purpose, these have wheels 57 and can be driven by means of a drive energy, which is only indicated by the reference number 59, and a drive that uses this. The hanging bags 5 have a rolling adapter 61 and a bag material suspended or suspended thereon, in particular a sagging and/or foldable material, in which a stored item 3 can be accommodated. In 3 A possible direction of movement of the hanging pockets 5 in the network 49 is indicated by means of a double arrow 51. The hanging pockets 5, in particular their rolling adapters 61, are set up, programmed and/or designed for autonomous or semi-autonomous driving on the network 49. For this purpose, they, in particular the rolling adapters 61, can have their own drive and their own longitudinal and transverse dynamics control.

In 2 the hanging pocket 5 is shown with the stored goods 3 held in it. The stored goods 3 are located within a U-shaped hanging material, in particular a flexible material. Loading and unloading can take place in particular from above or from the side.

4 shows a schematic view of a level of a hanging pocket storage, for example level 9 of the hanging pocket storage 1 described above. Level 9 is only partially shown, whereby the dimensions and number of individual elements of level 9 described here can be varied depending on the requirements of the hanging pocket storage 1. The number of levels themselves can also be varied.

Unless explicitly mentioned, reference is also made to the following figures. Level 9, which is only partially shown, has the network 49 with a large number of rails. The network 49 has, for example, rectangular meshes formed by the rails and crossings, whereby corresponding four-way switches can be provided at mesh nodes. The wheels 57 of the hanging pockets 5 can roll on the rails of the network 49. The hanging pockets 1 can move autonomously or at least partially autonomously. For this purpose, each of the hanging pockets 5 can have its own drive acting on the wheels 57 and a corresponding control system.

The network 49 can basically be driven over in any way by the hanging pockets 5, whereby the switches are preferably designed to be passive and the hanging pockets 5 interact with the switches by means of corresponding steering devices (not shown in detail) so that the desired change of direction can be achieved. Movements of the hanging pockets 5 are shown in bold dashed lines in the figure.

Preferably, however, the network 49 is used and driven by the hanging bags 5 - regardless of the previously described free driving and usage options - according to predetermined or predeterminable rules. For this purpose, certain sections of the network 5 can be specified, for example, directions, speeds and preferably types of use. In the present case, the network 49 can have at least one storage line 62 for storing the hanging bags 5. In the storage lines 62, one or more of the hanging bags 5 can be stored in a row 60, symbolized by a curved bracket, for example. For this purpose, they remain at rest, preferably in an energy-saving idle state, parked one behind the other in the row 60 of the corresponding storage lines 62.

For retrieval, all of the hanging pockets 5 that need to be moved can be woken up and moved again accordingly.

In this embodiment, storage lines 62 are all arranged parallel to one another throughout level 9 and are shown horizontally and as solid lines in the figure. The rules and the arrangement offer the advantage that material flows during storage and retrieval can be standardized and thus run faster, easier and free of resource conflicts on the network 49.

The hanging bags 5 are symbolized in the figure by rectangles. In comparison to other areas of the hanging bag warehouse 1, in particular highways and/or shunting roads, the storage streets 62 of the hanging bag warehouse 1 have a length without crossings, in particular one by a factor of at least 1.5, preferably of at least 3, in particular of at least 10, for example between 3 and 25, preferably of approximately 20. The length without crossings can be, for example, between 3 and 20 meters, preferably approximately 15 meters. The length of the storage streets 62 can be made dependent on the use or optimization of the hanging bag warehouse 1, for example rather shorter for quick access and short dwell times of the stored goods 3 and longer for comparatively low handling frequencies.

The hanging bag warehouse 1 also has shunting lines 66, preferably at least one shunting line 66. The shunting lines 66 are arranged at an angle to the storage lines 62, preferably orthogonal to them. In the figure, the shunting lines 66 are shown vertically and also as a solid line. Preferably, at least one of the storage lines 62 opens into at least one of the shunting lines 66 at the angle, preferably orthogonal. In comparison to the storage lines 62, it is not permitted to stop on the shunting lines 66 for storage purposes. A reversal of the direction of movement is optionally possible. In the present case, the storage lines 62, which are combined in blocks 76, open into two of the shunting lines 66 at least on one side, preferably on both sides and at the angle, in particular orthogonal. The blocks 76 each have a plurality of storage lines 62 arranged parallel to one another. In this case, 5 in each case. The number can vary, for example between 2 and 30, preferably between 5 and 20, in particular approximately 15. The number can also be adapted to a task of the hanging bag storage 1.

It is optionally conceivable that the blocks 76 are surrounded by a ring of shunting roads 66. However, expressways 72 are provided at an upper and/or lower end of the respective blocks 76 and parallel to the storage roads 62, preferably directly adjacent to each other.

In order to achieve a good and quick flow of the stored goods 3 or hanging bags 5, a comparatively high speed can be driven on the expressways 72 and in particular a continuous journey is provided, i.e. stopping without reason is not provided or should be avoided. Reasons for stopping can therefore preferably be limited to collision avoidance. Particularly preferably, the expressways 72 can have a direction-bound movement of the hanging bags 5 as a rule. Furthermore, it is optionally possible to that the expressways 72 are arranged parallel to one another at a certain distance, with the blocks 76 arranged in between. It is conceivable that the expressways 72 arranged parallel to one another have opposite specifications for the direction of movement, i.e. at least one pair of expressways 72 arranged parallel to one another with opposite specifications for the direction of movement is provided. In addition, the expressways 72 can be arranged at an angle to one another, preferably intersecting at the angle. For example, they can be arranged orthogonally to one another. In this case, the expressways 72 can be arranged in a grid and preferably with alternating specifications for the direction of movement to one another. In this way, ring roads can be formed which surround at least one or more of the blocks 76 and can be driven on particularly quickly in one direction. The optional alternating directions are shown in the figure by arrows 78 and the expressways 72 are shown in dashed lines.

It can be seen in the figure that the storage roads 62 are particularly preferably crossed at least on one side by one of the shunting roads 66 and one of the expressways 72 arranged at an angle to the storage roads 62 runs parallel to the respective shunting road 66. As shown in the figure, it is possible for one of the shunting roads 66 to be arranged parallel to both sides of each of the expressways 72, with one of the blocks 76 adjacent to each of them, with a large number of connections and junctions connecting one of the shunting roads 66 to the respective expressway 72 and in turn to the storage roads 62 of the respective blocks 76. A grid-like arrangement of at least two, preferably three rails of the network 49 running parallel to one another is thus formed, which has switches or crossings that can be driven over at least partially autonomously or autonomously at a distance of the storage roads 62 from the hanging pockets 5 and limits the trestles 76 orthogonally to the orientation of the storage roads 62 or connects them to the rest of the network 49 of the hanging pocket storage 1. The arrangement is divided by the traffic regulations into the shunting roads 66 and the expressways 72, whereby a physical structure can have identical parts of switches and rail sections in order to enable a cost-effective and easily assembled structure.

In the following, the possible uses of this grid-like arrangement of the storage roads 62, shunting roads 66 and expressways 72 are explained in more detail using the example of a relocation. One of the storage goods 3 stored in the hanging bag warehouse 1 is planned for relocation, for example a removal, preferably initially to the unloading station 55. The hanging bag 5 with the planned storage goods 3 is shown in dotted lines in the figure, whereby the storage goods 3 accommodated in the hanging bag 5 itself is not visible. The planned storage goods 3 can be identical in one or more locations in the hanging bag warehouse 1, whereby a selection can be made based on a criterion before planning.

As can be seen in the figure, the hanging pockets 5 shown in dotted lines are relocated, which are symbolized by dashed and bold arrows 74.

Before this can take place, however, the storage goods 3 shown in dotted lines are first scheduled for removal. This can be done using the control device 25.

In order to free up a retrieval path 70 on which the planned storage goods 3 can leave the row 60, further storage goods 3 are relocated to a shunting line 66, 68 of the hanging bag warehouse 1, shown in solid lines. The shunting line 66 is arranged orthogonally to the storage line 62 and intersects it at a four-way switch at one end of the storage line 62. As soon as the retrieval path 70 is free, the relocation or retrieval of the planned storage goods 3 can take place along it, which is symbolized in the figure by the bold and dashed arrow 74. The planned storage goods 3 can then optionally be temporarily stored or, if necessary, travel directly to or be conveyed to the unloading station 55, preferably drive into the ring conveyor system 23 and be conveyed to the unloading station by means of this.

4 shows a possibility for clearing the retrieval path 70 and moving the planned storage goods 3 on it. To do this, the other storage goods 3 are moved in a ring shape, which is symbolized by the arrow 80. The storage line 62 and another storage line 64 of the corresponding block 76 are used for circling, as shown by the dashed and bold arrow 80 in 4 marked.

When using the additional storage road 64, the shunting roads 66,68 are used on a particularly short section. This means that a comparatively large number of these processes can run in parallel and sorting and/or access times can be further shortened. As soon as the planned storage goods 3 have arrived at one end of the storage road 62, the retrieval path 70 is free and it can be relocated by crossing the shunting road 66 and over the expressway(s) 72, in particular outsourced, which is in 4 symbolized by the dashed and bold arrow 74.

Preferably, the hanging bags 5 or the stored goods 3 are rotated by a maximum of 180 degrees per removal. Preferably with an adjacent one of the storage lines 62. The stored goods 3 are therefore swapped between the storage lines 62, preferably between the two storage lines 62 arranged adjacent to one another, with the sequence of the stored goods 3 being reversed or mirrored and the removal taking place at the same time. This simplifies the management of the inventory, since the contents of the respective storage lines 62 are mirrored, but remain intact in their entirety except for the planned storage goods. The arrangement of the individual stored goods 3 within the storage lines 62 also plays no role. The planned storage goods 3 can move out autonomously and independently of the non-planned storage goods 3. It also does not matter which of the storage lines 62 also takes part in the rotation. It is only important that the planned one of the storage goods 3 is addressed and that the storage line 62 with this planned one of the storage goods 3 as well as any other, in particular directly adjacent, one of the storage lines 62 takes part in the rotation.

It is clear that half a rotation is sufficient for each of the storage goods 3 moved in this way on the two storage roads 62 to pass exactly once on one of the shunting roads 66, 68, which are arranged on both sides of the front sides of the storage roads 62. At this moment, the planned storage goods 3 leave the circular movement, in particular onto the corresponding shunting road 66, 68 or by crossing directly onto the adjacent or parallel expressway 72. In this application, circular movement or rotation can also be understood as a movement on a closed track that deviates from a pure circular shape.

The shunting roads 66 can be used in the same direction and are comparatively lightly congested due to the roundabout, which allows for more fluid traffic overall.

In a preferred option, the roundabout only takes place when a removal is taking place. Furthermore, the roundabout can only take place until the goods 3 to be removed from storage have left the roundabout. A decision can be made beforehand as to which of the shunting roads 66 and 68 they should leave the roundabout. Preferably in such a way that the roundabout movement is as small as possible and/or the route to the unloading station 55 is as short as possible. The roundabout can be left in the closer shunting road 66, 68 or expressway 72. In this case, the roundabout is basically left on both sides after a route optimization decision. This means that there is comparatively little traffic outside the storage roads 62 and 64.

Within block 76, two of the storage lines are preferably combined to form a roundabout, which have the same direction of rotation. These can be operated independently of one another. This makes it possible to dispense with at least one, preferably both, shunting lines 66 and 68, i.e. to provide only one of the shunting lines on one side or only one of the expressways 72 on both sides adjacent to the storage lines of block 76. This allows additional storage space to be freed up. A further block 77 of similar design is arranged adjacent to block 76. Such adjacent blocks 76, 77 can have opposite directions of rotation of the roundabouts, which in 4 is indicated by way of example by means of four curved arrows. This means that the then exclusively available expressways 72 or pairs consisting of one of the storage roads and one of the expressways can each be driven in one direction, which is symbolized by arrows 88.
